The lower side of the peripheral wall 26 a of the heater holder 26 is exposed from the can body 21 . The lower side of the peripheral wall 26 a has substantially the same outer diameter as the outer peripheral wall 21 d of the can body 21 . In addition, two air intake holes 26c penetrating in the radial direction are formed on the lower side of the peripheral wall 26a. The two intake holes 26c are disposed opposite to each other on both sides of the peripheral wall 26a with the main shaft O interposed therebetween. The two air intake holes 26c communicate the outside of the cartridge 3 (the interior of the cartridge housing portion 10 ) with the atomization chamber 24c. In addition, the air intake hole 26e penetrating in the main axis direction may not be formed in the bottom wall 26d of the heater holder 26 . The air intake hole 26e also communicates the outside of the cartridge 3 (inside the cartridge housing portion 10 ) with the atomizing chamber 24c.

On the bottom wall 26d of the heater holder 26, a plate-shaped partition wall 26f is erected along the main axis direction. In addition, the partition wall 26f extends in the radial direction, and both ends thereof are connected to the inner surface of the peripheral wall 26a. Two slits 26g penetrating in the main axis direction are formed in the bottom wall 26d. The two slits 26g are disposed across the partition wall 26f. Bent portions of the two planar electrodes 26h are inserted into the two slits 26g. The partition wall 26f prevents a short circuit between the two planar electrodes 26h and both ends of the heating wire 25b connected to the two planar electrodes 26h.

Returning to FIG. 5 , an engagement groove portion 26i is formed on the bottom wall 26d of the heater holder 26 . The three engaging groove portions 26i are arranged at equal intervals in the circumferential direction (at intervals of 120° in the circumferential direction). The engagement groove portion 26i is formed so as to open on the radially outer side and the lower side in the axial direction. The engagement groove portion 26i is formed in an isosceles trapezoidal shape when viewed from the radial direction, and has tapered legs (slopes) whose circumferential width gradually increases toward the lower side in the main axis direction. In addition, the number of engaging groove parts 25i should just be two or more, and is not limited to three. For example, six engaging groove portions 25i may be used.

The first rib 42C and the second rib 42D extend parallel to the longitudinal direction (Z-axis direction) of the main board 41 and are arranged to face each other in the short-side direction (Y-axis direction) of the main board 41 . In addition, the sub-board 42 is the same as the first rib 42C and the second rib 42D in the meaning of the "main board intersection" extending from the end of the main board 41 in a direction intersecting with the board surface of the main board 41, but holds the input device. 15. Components such as the display device 33 are different from the first rib 42C and the second rib 42D.

As shown in FIG. 10 , on the main plate 41 , a plurality of substrate support pieces 41 d are formed along the periphery of the first plate surface 41 a. The substrate supporting piece 41d supports the peripheral edge of the main substrate 31 (see FIG. 7 ), and forms a space with the first plate surface 41a. Thus, the holder 30 can hold the main substrate 31 on which electronic components are mounted on both surfaces.

The main substrate supported by the substrate supporting piece 41d in the thickness direction (X-axis direction) is formed on the first rib 42C (not shown, but the second rib 42D is the same) surrounding the first plate surface 41a. 31 clamping piece 42a. Moreover, the board|substrate support piece 41d is formed in the vicinity of 2nd rib 42D also in the same arrangement as 1st rib 42C. In addition, a substrate support piece 43e for supporting the main substrate 31 and a clamping piece 43f for sandwiching the main substrate 31 in the thickness direction (X-axis direction) are also formed on the bottom wall 43b of the receiving portion 43 .

The two engaging claws 41f are arranged to face each other along the longitudinal direction (Z-axis direction) of the main plate 41 at the peripheral portion of the opening 41c. In addition, the tray 44 is formed in a rectangular shape extending in the Z-axis direction when viewed from the X-axis direction.

Fig. 12 is a sectional view taken along arrow BB shown in Fig. 3 . FIG. 12 shows a section through the two engaging claws 41 f and the tray 44 .

As shown in FIG. 12 , the two engaging claws 41 f are engaged with the peripheral edge portions of the upper side (+Z side) and the lower side (−Z side) of the tray 44 in the longitudinal direction. In addition, the peripheral edge portions of the right side (+Y side) and the left side (−Y side) in the short-side direction of the tray 44 that are not engaged with the two engaging claws 41 f are placed on the first plate surface 41 a.

The tray 44 is recessed toward the −X side with respect to the first plate surface 41 a of the main plate 41 so as to avoid the thickness of the oscillator 36 in the X-axis direction. The sub-board 32 is disposed on a recessed portion of the tray 44 . The sub-board 32 is electrically connected to an unillustrated connection terminal of the oscillator 36 . In addition, an opening 32 b for avoiding interference with the eccentric weight 36 a of the oscillator 36 is formed in the sub-board 32 . In addition, as shown in FIG. 12 , it is not necessary to bring the sub-substrate 32 into contact with the oscillator 36 , and only an unillustrated connection terminal of the oscillator 36 may be electrically connected to the sub-substrate 32 .

In addition, in order to facilitate the transmission of the vibration of the oscillator 36 to the first housing 13A, part or all of the main body of the oscillator 36 may be directly in contact with the first housing 13A.

Returning to FIG. 10 , the sub-plate 42 extends in a direction (X-axis direction) perpendicular to the plate surfaces (the first plate surface 41 a and the second plate surface 41 b ) of the main plate 41 . The sub-plate 42 of this embodiment extends to both sides (+X side and -X side) in the direction orthogonal to the board surface of the main board 41 (refer FIG. 12). Thereby, the cross section of the holder 30 becomes T-shape, and the rigidity of the holder 30 can be improved.

As shown in FIG. 10 , the sub-plate 42 has a first sub-plate 42A provided on the first end side 41h1 of the end of the main board 41 and a second end side adjacent to the first end side 41h1 provided on the end of the main board 41. 41h2 of the second sub-plate 42B.

As shown in FIG. 11 , the first sub-plate 42A disposed on the first end side 41h1 is connected to the second sub-plate 42B disposed on the second end side 41h2 . The rigidity of the holder 30 can be further improved by connecting the first sub-plate 42A and the second sub-plate 42B having a T-shaped cross section to each other. The first sub-plate 42A is connected to the second sub-plate 42B at an obtuse angle. Thereby, the input device 15 can be held by tilting the second sub-plate 42B so as to face the rounded first corner portion 12C1 .

In addition, the angle formed by the first sub-board 42A and the second sub-board 42B is the angle formed by the first end side 41h1 and the second end side 41h2 of the main board 41 . That is, the first sub-plate 42A and the second sub-plate 42B are connected at an obtuse angle of approximately 135°. In addition, as long as the first sub-plate 42A and the second sub-plate 42B are connected within a range larger than 90° and smaller than 180°, they are not limited to the structure connected at approximately 135°.

As shown in FIG. 11, the positioning convex part 42a1 is formed in 42 A of 1st sub-plates. The positioning convex part 42a1 is a protrusion part which positions the above-mentioned frame-shaped display device holder 33b (refer FIG. 7). As shown in FIG. 12, the positioning convex part 42a1 and the display device holder 33b form the same plane (XY plane). Thereby, the adhesive sheet 45 for bonding the display device main body 33a is easily pasted.

Moreover, as shown in FIG. 11, the sub-plate extension part 42a2 is formed in 42 A of 1st sub-plates. The sub-plate extension part 42a2 is arrange|positioned at the end part of the side opposite to the end part of the side connected to the 2nd sub-plate 42B of 42 A of 1st sub-plates. The sub-plate extension part 42a2 extends and protrudes to +Y side rather than the 2nd rib 42D. As shown in FIG. 8 , the engaging claws 14b1 of the display cover 14 are engaged with the sub-plate extending protrusion 42a2.

As shown in FIG. 11, the wiring groove 42b1 and the board|substrate holding piece 42b2 are formed in the 2nd sub-plate 42B. The substrate holding pieces 42b2 are four L-shaped protrusions that hold the four corners of the above-mentioned switch substrate 15b (see FIG. 7 ). The wiring groove 42b1 is a groove through which wiring connecting the switch substrate 15b and the main substrate 31 passes. The wiring groove 42b1 is formed across the area surrounded by the four substrate holding pieces 42b2.

In addition, the sub-plate extension part 42b3 is also formed in the 2nd sub-plate 42B. The sub-plate extension part 42b3 is arrange|positioned at the end part of the side opposite to the end part of the side connected to the 1st sub-plate 42A of the 2nd sub-plate 42B. The sub-plate extension part 42b3 extends and protrudes to -Y side rather than the 1st rib 42C. As shown in FIG. 8 , the other engaging claw 14b2 of the display cover 14 is engaged with the extension protrusion 42b3 of the sub-plate.

FIG. 14 is a perspective view showing an attachment structure of the monitor cover 14 according to one embodiment.

As shown in FIG. 14 , the display cover 14 has a curved shape convex upward (+Z side). The above-mentioned engaging claw 14b1 is arranged at the end portion on the right side (+Y side) of the monitor cover 14 . The above-mentioned engagement claw 14b2 is arrange|positioned at the edge part of the left side (-Y side) of the display cover 14 on the side opposite to the engagement claw 14b1.

The engaging claw 14b1 is engaged with the sub-plate extension protrusion 42a2 of the first sub-plate 42A. Moreover, the engaging claw 14b2 is engaged with the sub-plate extension protrusion part 42b3 of the 2nd sub-plate 42B. As shown in FIG. 8 , the display cover 14 in the assembled state is engaged with the holder 30 in a state spanning from end to end of the first sub-panel 42A and the second sub-panel 42B.

As shown in FIG. 14 , a through hole 14 a in which the switch button 15 a of the input device 15 is disposed is formed in the display cover 14 . The switch button 15a has a base portion 15a1 abutting on the switch substrate 15b, and a cylindrical button portion 15a2 protruding from the base portion 15a1. The button part 15a2 is inserted and arrange|positioned through the through-hole 14a.

The button portion 15a2 is formed of, for example, a hard resin material or the like. An elastic body (such as a spring) not shown is provided inside the button part 15a2, and when the button part 15a2 is released, it returns to the original position. In addition, the button portion 15a2 may be an elastic body that can be elastically deformed by pressing. In this case, a rigid body that can be displaced by pressing (a cylinder that is pressed into the auxiliary switch substrate 15b, etc.) may be contained inside the elastic body. The insertion hole 15a3 is formed in the peripheral surface of the button part 15a2. The insertion hole 15a3 is formed at the base of the button portion 15a2 (near the connection portion of the button portion 15a2 to the base portion 15a1).

The switch holder 15c is formed in an annular shape that can be fitted on the button portion 15a2. The switch holder 15c is formed of a flexible material deformable by pressing the button portion 15a2. In addition, the switch holder 15c may also be formed of an elastically deformable material. On the inner diameter side of the switch holder 15c, an inner diameter side protruding piece 15c1 capable of being inserted into the insertion hole 15a3 of the button portion 15a2 is formed. In addition, two radially outer projection pieces 15c2 protruding to both sides in the X-axis direction are formed on the radially outer side of the switch holder 15c. The radially inner projecting piece 15c1 and the two radially outer projecting pieces 15c2 are out of phase by 90° around the center axis of the switch holder 15c. The switch holder 15c covers the base portion 15a1 of the switch button 15a. Therefore, the base portion 15a1 can be prevented from being seen from the display cover 14 side.

Side walls 14 c are vertically provided on both sides in the X-axis direction in the vicinity of the through hole 14 a of the display cover 14 . Two insertion holes 14c1 into which the two radially outer protrusion pieces 15c2 of the switch holder 15c can be inserted are formed in the side wall 14c. The switch holder 15c and the switch button 15a, in other words, the components of the input device 15 other than the switch substrate 15b are assembled on the display cover 14 side. When the display cover 14 assembled with the switch holder 15c and the switch button 15a is engaged with the holder 30, the switch button 15a is placed on the switch substrate 15b, and the assembly of the input device 15 is completed.

Returning to FIG. 11 , the first rib 42C of the holder 30 extends in the longitudinal direction (Z-axis direction) along the end portion on the −Y side of the main plate 41 . The end portion on the upper side (+Z side) in the longitudinal direction of the first rib 42C is connected to the second sub-plate 42B. The rigidity of the holder 30 can be further increased by connecting the first rib 42C having a T-shaped cross section to the second sub-plate 42B together with the main plate 41 . A case fitting portion 42E protrudes from a side surface of the first rib 42C facing the side opposite to the main plate 41 (−Y side).

A first fitting hole 42e1 and a second fitting hole 42e2 are formed in the case fitting portion 42E. The 1st fitting hole 42e1 and the 2nd fitting hole 42e2 open to -Y side. The first fitting hole 42e1 is arranged on the +X side of the case fitting portion 42E. The above-mentioned first housing 13A is claw-fitted into the first fitting hole 42e1. The second fitting hole 42e2 is arranged on the -X side of the case fitting portion 42E. The above-mentioned second housing 13B is claw-fitted into the second fitting hole 42e2.

Two case fitting portions 42E are formed separately in the longitudinal direction of the first rib 42C. A set of first fitting holes 42e1 and second fitting holes 42e2 are formed in the case fitting portion 42E disposed on the lower side (−Z side) in the longitudinal direction of the first rib 42C. A plurality of sets of first fitting holes 42e1 and second fitting holes 42e2 are separately formed in the longitudinal direction in the case fitting portion 42E disposed on the longitudinal upper side (+Z side) of the first rib 42C. Moreover, the through-hole 30a for screwing the holder 30 is formed in the case fitting part 42E arrange|positioned at the +Z side.

A clamped piece 42e3 linearly partitioning between the first fitting hole 42e1 and the second fitting hole 42e2 is protrudingly provided on the housing fitting portion 42E disposed on the +Z side. The sandwiched piece 42e3 is sandwiched between the first peripheral wall portion 12B1 of the first housing 13A and the second peripheral wall portion 12B2 of the second housing 13B. In addition, as shown in FIG. 1 , the held piece 42 e 3 is not exposed on the outer surface 12 b 1 of the peripheral wall portion 12B of the exterior case 12 . That is, a step that sandwiches the held piece 42e3 is formed inside the first peripheral wall portion 12B1 and the second peripheral wall portion 12B2.

As shown in FIG. 11 , the second rib 42D of the holder 30 extends in the length direction (Z-axis direction) along the +Y-side end portion of the main plate 41 . The end of the second rib 42D on the upper side (+Z side) in the longitudinal direction is connected to the first sub-plate 42A. Together with the main plate 41 , the second rib 42D having a T-shaped cross section is connected to the first sub-plate 42A, whereby the rigidity of the retainer 30 can be further increased.

The second rib 42D has a branch portion 42D1 bent in an L-shape toward the side (+Y side) opposite to the main plate 41 . The branch portion 42D1 is connected to the peripheral wall 43 a of the receiving portion 43 . Thereby, the rigidity of the connection part of the main board 41 and the receiving part 43 can be improved. In addition, as shown in FIG. 10 , a through-hole 30 a for screwing the holder 30 is formed at a connection portion between the main plate 41 and the receiving portion 43 .

A stepped notch 42d is formed in the second rib 42D. The notch portion 42d has a first notch portion 42d1 and a second notch portion 42d2. The first notch portion 42d1 is formed in front of the main plate 41 from the end portion on the +X side of the second rib 42D toward the end portion on the −X side. The 2nd notch part 42d2 is arrange|positioned at the -Z side of the 1st notch part 42d1. The second notch 42d2 is formed from the +X side end toward the −X side end of the second rib 42D to the rear side of the main plate 41 (a position beyond the second plate surface 41b) (see FIG. 11 ).

The first notch portion 42d1 is formed to avoid interference with an optical path of a light source 52 (see FIG. 29 described later) provided on the main substrate 31 which will be described later. The light source 52 is, for example, an LED lamp or the like. As shown in FIG. 29 , the second notch 42 d 2 is formed to avoid interference with the sensor holder 35 mounted on the cartridge housing 10 and the sensor 34 held by the sensor holder 35 .

FIG. 15 is a plan view of a holder 30 according to one embodiment. Fig. 16 is a cross-sectional view taken along arrow CC shown in Fig. 15 .

As shown in FIG. 15 , the receiving portion 43 of the holder 30 is formed in a bottomed cylindrical shape. Two insertion holes 43 c for arranging two protruding electrodes 50 (see FIG. 7 ) in the cartridge housing portion 10 are formed on the bottom wall 43 b of the receiving portion 43 .

The two insertion holes 43c are arranged separated in the Y-axis direction with the main axis O interposed therebetween. The two insertion holes 43c penetrate the bottom wall 43b in the main axis direction (Z-axis direction). As shown in FIG. 10 , an annular wall 43 d protrudes from the lower surface side (−Z side) of the bottom wall 43 b. The annular wall 43d surrounds the two insertion holes 43c. The annular wall 43d is formed in the shape of a long hole connecting two ends of two parallel lines extending in the Y-axis direction in a circular arc when viewed from below.

As shown in FIG. 16 , a step 43g (ring-shaped receiving surface) abutting against the cartridge housing 10 in the main axis direction (Z-axis direction) is formed inside the peripheral wall 43a of the receiving portion 43 . The peripheral wall 43a on the lower side (−Z side) than the step 43g is smaller in diameter than the upper side (+Z side) of the step 43g. As shown in FIG. 15 , the peripheral wall 43a on the lower side than the step 43g has an inner diameter D1. The inner diameter D1 corresponds to the inner diameter of the cartridge housing portion 10 .

On the upper surface side (+Z side) of the bottom wall 43 b of the receiving portion 43 , an engaging protrusion 43 h that engages with the engaging groove portion 26 i (see FIG. 5 ) of the cartridge 3 described above is formed. The engaging groove portion 26i and the engaging protrusion portion 43h constitute a positioning mechanism 90 for positioning the cartridge 3 in the circumferential and radial directions. Three engaging protrusions 43h are formed at equal intervals in the circumferential direction (at intervals of 120° in the circumferential direction). In addition, the number of engagement protrusions 43h is not limited to the same number as the number of engagement grooves 26i. The number of engaging protrusions 43h may be equal to or less than the number of engaging grooves 26i.

As shown in FIG. 16 , the engaging protrusion 43h has a curved shape protruding upward in the main axis direction (+Z side). That is, the circumferential width of the engaging protrusion 43h becomes smaller toward the upper side in the main axis direction. In addition, the engagement protrusion 43h may be in the same shape as the engagement groove 26i, such as an isosceles trapezoid or an isosceles triangle, as long as the circumferential width becomes smaller toward the upper side in the main axis direction. In addition, the engaging protrusion 43h may have an asymmetric shape such as a right triangle. For example, when the engaging protrusion 43h is a right triangle, when the mouthpiece 11 is connected to the cartridge housing 10, the side opposite to the rotation direction of the mouthpiece 11 is preferably a right angle side. As a result, when the mouthpiece 11 is connected to the cartridge storage part 10, it is difficult for the cartridge storage part 10 to go over the engagement protrusion 43h.

As shown in FIG. 15 , the outer diameter D2 of the cartridge 3 accommodated in the cartridge housing portion 10 is smaller than the inner diameter D1 of the cartridge housing portion 10 . The gap generated between the inner diameter D1 of the cartridge receiving portion 10 (in other words, the inner diameter D1 on the lower side from the step 43g of the receiving portion 43 ) and the outer diameter D2 of the cartridge 3 is larger than the inner diameter D1 of the cartridge receiving portion 10 2.6% better. As a result, the gap between the pod storage portion 10 and the pod 3 becomes larger, and it is easy to introduce the engaging protrusion 43h into the engaging groove 26i when the pod 3 is installed later. The gap between the pod storage portion 10 and the pod 3 mentioned here is calculated according to the difference between the inner diameter D1 of the pod storage portion 10 and the outer diameter D2 of the pod 3 . For example, when the inner diameter D1 is 11.8 mm and the outer diameter D2 is 11.5 mm, the clearance is 0.3 mm. This gap corresponds to 2.54% of the inner diameter D1, which is excluded from the above conditions.

More preferably, the gap formed between the inner diameter D1 of the cartridge housing portion 10 and the outer diameter D2 of the cartridge 3 is larger than 7.0% of the inner diameter D1 of the cartridge housing portion 10 . As a result, the gap between the pod storage portion 10 and the pod 3 becomes larger, and it is easier to introduce the engaging protrusion 43h from the engaging groove 26i when the pod 3 is installed as described later. For example, when the inner diameter D1 is 12.4 mm and the outer diameter D2 is 11.5 mm, the gap is 0.9 mm. This gap corresponds to 7.26% of the inner diameter D1, and in this case, the above-mentioned conditions are met.

The radial dimension D3 of the engagement protrusion 43 h is preferably larger than the gap formed between the cartridge housing portion 10 and the cartridge 3 . In addition, when the above-mentioned two conditions are defined by the dimension D3 in the radial direction of the engagement protrusion 43h, it will be as follows. The engagement protrusion 43h is radially from the inner peripheral wall of the cartridge storage portion 10 (in other words, the inner peripheral wall of the peripheral wall 43a on the lower side than the step 43g) towards the inner side of the cartridge storage portion 10 to be larger than the cartridge storage portion 10 Dimension D3 extends better by 2.6% of inner diameter D1. More preferably, the engaging protrusion 43h extends radially from the inner peripheral wall of the cartridge housing 10 toward the inside of the cartridge housing 10 with a dimension D3 greater than 7.0% of the inner diameter D1 of the cartridge housing 10 .

As shown in FIG. 15 , an engagement protrusion 43i for positioning the cartridge storage portion 10 in the circumferential direction is formed on the step 43g of the receiving portion 43 . One engaging protrusion 43 i is formed on the inner wall surface on the front side (+X side) of the peripheral wall 43 a of the receiving portion 43 . The engagement protrusion 43i does not protrude radially inward from the step 43g of the receiving portion 43, but is formed to protrude to the same extent as the peripheral wall 43a below the step 43g. As shown in FIG. 16 , the engaging protrusion 43i has a curved surface shape protruding upward in the main axis direction (+Z side) like the engaging protrusion 43h. That is, the circumferential width of the engaging protrusion 43 i becomes smaller toward the upper side in the main axis direction.

FIG. 17 is a front view of the pod storage unit 10 according to one embodiment. Fig. 18 is a right side view of the pod housing 10 according to one embodiment. FIG. 19 is a left side view of the pod storage unit 10 according to one embodiment. Fig. 20 is a sectional view taken along arrow DD shown in Fig. 18 .

As shown in FIG. 17 , the cartridge housing portion 10 is a cylindrical member extending along the main axis direction (Z-axis direction). While the exterior case 12, the holder 30, and the like are made of resin, the pod storage portion 10 is formed of a metal cylindrical member.

A cartridge insertion opening 10 a is formed at an end portion on the upper side (+Z side) of the cartridge receiving portion 10 in the main axis direction. On the other hand, an engaging groove portion 10 b that engages with the above-mentioned engaging protrusion 43 i is formed at an end portion on the lower side (−Z side) in the main axis direction of the cartridge housing portion 10 . One engaging groove portion 10 b is formed on the front side (+X side) of the lower end portion of the cartridge housing portion 10 .

As shown in FIG. 18 , a through hole 10 c and two air communication holes 10 e are formed on the right side (+Y side) of the peripheral surface of the cartridge housing portion 10 . A cartridge housing side protrusion 17C (see FIG. 29 to be described later) provided on the cover member 17 (see FIG. 7 ) described later is inserted into the through hole 10 c. The two air communication holes 10e communicate with the two air holes 19 provided in the cover member 17 (see FIG. 29 described later).

As shown in FIG. 18 , the through hole 10 c is a long hole extending in the main axis direction (Z-axis direction). A rectangular groove 10c1 is formed at the end edge on the −X side of the through hole 10c. The rectangular groove 10c1 makes the shape of the through hole 10c asymmetrical in the X-axis direction in order to prevent wrong assembly of the cover member 17 with respect to the cartridge housing portion 10 . The two air communication holes 10e are arranged to sandwich the through-hole 10c in the X-axis direction. The air communication hole 10 e is formed larger than the air hole 19 as shown in FIG. 29 described later. Thereby, the non-communication of the air hole 19 and the air communication hole 10e, and the positional displacement which narrows a flow path area can be prevented. That is, it is difficult for the air hole 19 to be blocked when the main body unit 2 is assembled.

As shown in FIG. 19 , another through hole 10 d is formed on the left side (−Y side) of the peripheral surface of the cartridge housing portion 10 . A cartridge housing side protrusion 35D (see FIG. 29 described later) provided on the sensor holder 35 (see FIG. 7 ) described later is inserted into the through hole 10 d. The through hole 10d is an elongated hole extending in the main axis direction (Z-axis direction). The through hole 10d is arranged on the obliquely left front side (+X side) of the cartridge housing portion 10. As shown in FIG. The positional relationship of the point symmetry of the center.

As shown in FIG. 20 , in the cartridge housing portion 10 , an insert ring 10A is press-fitted on the upper side (+Z side) of the through hole 10 c and the through hole 10 d in the main axis direction. The insert ring 10A is a cylindrical member made of resin. A mouthpiece connection portion 10B for connecting the mouthpiece portion 11 (see FIG. 5 ) to the cartridge insertion opening 10 a is formed on the insertion ring 10A. In addition, a recess 10f is formed on the inner wall surface of the pod storage portion 10 on the upper side (+Z side) in the main axis direction, so that the inner diameter will not be reduced due to the insertion of the insertion ring 10A.

Two suction port connection portions 10B are formed at equal intervals (180°) in the circumferential direction of the fitting ring 10A. The suction port connection portion 10B is a groove (notch) formed in the fitting ring 10A. The suction port connection part 10B has the 1st groove part 10b1, the 2nd groove part 10b2, and the 3rd groove part 10b3. The width of the first groove portion 10b1 in the circumferential direction increases toward the upper side (+Z side) in the main axis direction. The second groove portion 10b2 extends from the lower end of the first groove portion 10b1 to the lower side (−Z side) in the main axis direction with a constant width. The third groove portion 10b3 is bent at 90° in the circumferential direction from the lower end of the second groove portion 10b2 , and surrounds the fitting ring 10A approximately 1/4 turn with a constant width.

＜Suction part＞

Fig. 21 is a right side view of the mouthpiece 11 according to the embodiment. Fig. 22 is a sectional view taken along arrow EE shown in Fig. 21 .

As shown in FIG. 21 , the mouthpiece 11 has a protruding portion 11b1 that engages with the mouthpiece connection portion 10B of the pod housing 10 described above. The mouthpiece 11 includes a resin mouthpiece main body 11A and a metal cylinder 11B in which two protrusions 11b1 are formed as shown in FIG. 22 .

As shown in FIG. 22 , the mouthpiece main body 11A is formed in a bottomed cylindrical shape. The aforementioned flavor source container 4 is inserted into the inner side of the peripheral wall 11a1 of the mouthpiece body 11A (see FIG. 6 ). On the outer surface of the peripheral wall 11a1, a flange portion 11a2 extending radially outward is provided in an annular shape. As shown in FIG. 6 , the flange portion 11 a 2 abuts against the upper opening edge of the cartridge receiving portion 10 (the opening edge of the cartridge insertion opening 10 a ) in the main axis direction (Z-axis direction).

A through-hole 11a4 penetrating in the main axis direction is formed in the bottom wall 11a3 of the mouthpiece main body 11A. The cartridge abutting portion 60 is embedded in the through hole 11a4 (see FIG. 6 ). The pod abutting portion 60 is, for example, an elastic body formed of a resin material such as silicone resin. The cartridge abutting portion 60 includes a first ring portion 60a, a cylindrical portion 60b and a second ring portion 60c.

The 1st ring part 60a is arrange|positioned at the axial direction upper side (+Z side) of the bottom wall 11a3 of 11 A of nozzle part main bodies. The first ring portion 60a has an outer diameter larger than the through hole 11a4, and extends to the inner wall surface of the peripheral wall 11a1 of the mouthpiece body 11A. The first ring portion 60a is in contact with the bottom wall 27d of the flavor source container 4 inside the peripheral wall 11a1. The side facing the bottom wall 27d of the fragrance source container 4 of the first ring portion 60a may be a flat surface, or may have grooves formed to match the shape of the legs of the bottom wall 27d. The first ring portion 60a becomes the anti-slip member of the fragrance source container 4 in the circumferential direction and the sealing chamber of the fine holes 27e of the fragrance source container 4 . In addition, the first ring portion 60 a does not need to be in contact with the bottom wall 27 d of the fragrance source container 4 . In this case, a sealing portion that prevents the introduction of outside air can be formed at the contact portion between the flavor source container 4 and the mouthpiece 11 in the step 27b. The cylindrical part 60b is inserted in the through-hole 11a4 of the bottom wall 11a3, and is arrange|positioned. The cylindrical portion 60b connects the inner diameter side of the first ring portion 60a and the inner diameter side of the second ring portion 60c in the main axis direction.

The 2nd ring part 60c is arrange|positioned at the main-axis direction lower side (-Z side) of the bottom wall 11a3 of 11 A of nozzle part main bodies. The second ring portion 60c has a large outer diameter through hole 11a4 extending to the inner wall surface of the cylindrical body 11B. An annular protrusion 61 protruding downward in the main axis direction toward the cartridge 3 is formed on the second ring portion 60c. Through the annular protrusion 61, the contact between the second ring portion 60c and the pod 3 is no longer planar contact, the contact pressure relative to the pod 3 increases, and the friction force in the circumferential direction and the pressing force in the main axis direction described later are easy to appear. .

A communicating hole 62 is formed at the centers of the first ring portion 60a, the cylindrical portion 60b, and the second ring portion 60c. The communication hole 62 communicates the through hole 21 b of the tank body 21 of the above-mentioned cartridge 3 with the fine hole 27 e of the flavor source container 4 . The annular protrusion 61 of the second ring portion 60c is formed in a double ring shape. The annular protrusion 61 abuts against the top wall 21a of the can body 21 around the through hole 21b of the cartridge 3, thereby forming a double seal with high airtightness.

Returning to FIG. 22 , the cylindrical body 11B is press-fitted onto the peripheral wall 11a1 of the mouthpiece main body 11A that is lower than the flange portion 11a2 . Two protrusions 11b1 are arranged at equal intervals (180°) in the circumferential direction on the peripheral surface of the cylindrical body 11B. The cylindrical body 11B extends toward the lower side (−Z side) in the main axis direction than the peripheral wall 11 a 1 of the mouthpiece body 11A. The second ring portion 60c described above is arranged in a space below the bottom wall 11a3 surrounded by the cylindrical body 11B. In addition, as shown in FIG. 6 , the inner diameter of the barrel 11B is larger than the outer diameter of the cartridge 3 . Therefore, even in a state shown in FIG. 37 to be described later, the mouthpiece 11 is strongly pressed toward the cartridge 3, and the second ring portion 60c is elastically deformed to be crushed in the main axis direction, and the cylindrical body 11B will not Interfere with pod 3.

＜Main PCB＞

FIG. 23 is a perspective view of a main substrate 31 according to one embodiment. FIG. 24 is a perspective view showing a state where the protruding electrode cover 51 is removed from the protruding electrode 50 of the main substrate 31 according to one embodiment.

As shown in FIG. 23, the main substrate 31 has a plate shape extending along the YZ plane, and has a first plate surface 31a facing the front side (+X side) and a second plate surface 31b facing the rear side (-X side). . On the second plate surface 31b of the main substrate 31, there are: a protruding electrode 50 inserted into the internal space formed by the above-mentioned cartridge storage part 10 and the receiving part 43, that is, the cartridge storage chamber; and the inside of the cartridge storage part 10 The light source 52 illuminates. In addition, the protruding electrode 50 can reach the inside of the cartridge storage part 10 in the cartridge storage chamber, or can only reach the inside of the receiving part 43 . In addition, when the receiving portion 43 is in the shape of a flat plate, the protruding electrodes 50 can easily reach the inside of the cartridge housing portion 10 .

Here, the “main substrate” refers to the largest substrate among the substrates accommodated inside the exterior case 12 . The main substrate 31 is larger than the aforementioned sub-substrate 32, the switch substrate 15b of the input device 15, and the like. In addition, when only one board|substrate is accommodated inside the exterior case 12, this board|substrate is a "main board|substrate". In addition, when two substrates of the same size are accommodated inside the exterior case 12, the substrate provided with an electronically controlled calculation unit such as a CPU or a microcomputer is referred to as a "main substrate".

The main substrate 31 has a first portion 31A extending in the main axis direction (Z-axis direction) and a second portion 31B extending in a direction intersecting the first portion 31A. The second portion 31B extends in the Y-axis direction orthogonal to the direction in which the first portion 31A extends. That is, the main substrate 31 is formed in an L-shape when viewed from the X-axis direction. In addition, as long as the second portion 31B can extend to the lower side (−Z side) of the receiving portion 43 shown in FIG. 10 , it does not necessarily have to be bent at a right angle with respect to the first portion 31A. That is, the shape of the main substrate 31 is not limited to the L-shape.

The first portion 31A is a portion overlapping the main plate 41 of the holder 30 shown in FIG. 10 . The first part 31A is held on the main plate 41 by the board support piece 41d and the holding piece 42a. The first portion 31A extends in the main axis direction along the main plate 41 . That is, the first portion 31A extends parallel to the cartridge housing portion 10 . The light source 52 is disposed on the cartridge housing portion 10 side (+Y side) of the first portion 31A (see FIG. 23 ).

The second portion 31B is a portion extending from the main plate 41 of the holder 30 shown in FIG. 10 toward the receiving portion 43 side (+Y side). The second portion 31B is held by the substrate supporting piece 43 e and the clamping piece 43 f of the bottom wall 43 b of the receiving portion 43 . The second portion 31B is arranged to face the receiving portion 43 (that is, the end portion of the cartridge housing portion 10 ) in the main axis direction (Z-axis direction). In other words, the second portion 31B and the receiving portion 43 are arranged to line up in the main axis direction. The protruding electrodes 50 are arranged on the side (+Z side) of the second portion 31B facing the receiving portion 43 (see FIG. 23 ).

As shown in FIG. 24 , the protruding electrodes 50 are supported by a seat portion 50A provided on the second plate surface 31 b of the main substrate 31 . The pedestal portion 50A supports the protruding electrodes 50 so as to be parallel to the plate surfaces (the first plate surface 31 a and the second plate surface 31 b , in other words, the YZ plane) of the main substrate 31 . That is, the two terminals + and − of the protruding electrode 50 supported by the pedestal portion 50A extend parallel to the YZ plane.

The main substrate 31 is provided with a protruding electrode cover 51 covering the portion where the protruding electrode 50 is provided. The portion where the protruding electrode 50 is provided includes the pedestal portion 50A. Specifically, the portion where the protruding electrode 50 is provided includes the pedestal portion 50A, the base of the protruding electrode 50 , and the peripheral region of the pedestal portion 50A in the second plate surface 31 b. The protruding electrode cover 51 is formed in a substantially box shape with an open side facing the second plate surface 31b. The protruding electrode cover 51 has a cover end wall 51 a disposed on the −X side of the base portion 50A, and cover peripheral walls 51 b surrounding the base portion 50A on both sides in the Y-axis direction and on both sides in the Z-axis direction.

Two through-holes 51c through which the protruding electrodes 50 are arranged to pass through are formed in the wall portion on the +Z side of the cover peripheral wall 51b. In addition, the tip portion of the protruding electrode 50 is biased toward the +Z side by a spring member (not shown) accommodated at the base of the protruding electrode 50 and is freely displaceable in the Z-axis direction. That is, the protruding electrodes 50 extend toward the cartridge 3 and are displaced in the -Z direction when the cartridge 3 is inserted. Also in this state, since the protruding electrode 50 is urged in the +Z direction, it can reliably contact the cartridge 3 . The inner wall surface of the through hole 51 c is in close contact with a portion that does not restrict the displacement of the tip portion of the protruding electrode 50 , for example, the outer periphery of the base of the protruding electrode 50 in this embodiment.

Fig. 25 is a sectional view taken along the line FF shown in Fig. 9 .

As shown in FIG. 25 , the protruding electrode cover 51 abuts against the receiving portion 43 of the holder 30 in which the insertion hole 43 c is formed. The protrusion electrode 50 is inserted into the insertion hole 43c. The wall portion on the +Z side of the cover peripheral wall 51 b of the protruding electrode cover 51 is in contact with the annular wall 43 d of the bottom wall 43 b of the receiving portion 43 in the axial direction. The protruding electrode cover 51 is formed of silicone resin. The wall portion on the +Z side of the cover peripheral wall 51b is elastically deformed by contact with the annular wall 43d.

The bottom wall 43 b of the receiving portion 43 is provided with a substrate abutting portion 43 j. The substrate contact portion 43j is arranged on the +X side of the annular wall 43d. The substrate abutting portion 43 j is provided to protrude toward the −Z side from the bottom wall 43 b of the receiving portion 43 , and abuts against the main substrate 31 in the axial direction. As shown in FIG. 10 , the substrate abutting portion 43j is arranged between the substrate supporting piece 43e and the clamping piece 43f provided on the bottom wall 43b, and extends linearly in the Y-axis direction.

As shown in FIG. 25 , the annular wall 43 d extends toward the −Z side beyond the substrate contact portion 43 j. Elastic deformation of the protruding electrode cover 51 by the annular wall 43d is limited to a constant amount by the abutment of the substrate abutting portion 43j on the main substrate 31 . That is, the contact pressure between the annular wall 43d and the protruding electrode cover 51 can be managed by the substrate contact portion 43j. Therefore, the protruding electrode cover 51 is not pressed excessively against the annular wall 43d, and the sealing performance between the annular wall 43d and the protruding electrode cover 51 can be ensured.

The protruding electrode cover 51 is provided on the main substrate 31 together with the protruding electrode 50 . That is, the protruding electrode cover 51 is not held by a structure other than the main substrate 31 (for example, the exterior case 12 or the like). In addition, as shown in FIG. 25 , the protruding electrode cover 51 is assembled to the exterior case 12 in a non-contact state. Accordingly, it is possible to prevent the protruding electrode cover 51 from contacting with the outer case 12 to cause deformation or misalignment to impair the performance of the sheath.

＜Cover part＞

FIG. 26 is a view of the cover member 17 according to one embodiment viewed from the radially outer side. FIG. 27 is a view of the cover member 17 according to one embodiment viewed from the radially inner side. FIG. 28 is a perspective view of the cover member 17 according to one embodiment.

As shown in FIG. 26 , the cover member 17 includes a main body case side protrusion 17A on the radially outer side, in other words, toward the right side (+Y side) of the main body case 13 . The main body case side protrusion 17A is inserted into the opening 13 a of the main body case 13 as shown in FIG. 2 . The cover member 17 is translucent, and the liquid remaining amount of the aerosol source of the pod 3 accommodated in the pod storage portion 10 can be checked through the main body casing side protrusion 17A.

The main body case side protrusion 17A is formed in the same shape as the opening 13 a of the main body case 13 and extends in the main axis direction (Z-axis direction). The main body case side protrusion 17A is slightly smaller than the opening 13a. An air intake port 18 is formed in a gap between the main body case side protrusion 17A and the opening portion 13a. In addition, a part of the main body case side protrusion 17A may be in contact with the inner wall surface of the opening 13 a. The air intake port 18 is an inlet of an intake flow path that takes in external air into the interior of the exterior case 12 by user's suction.

The air intake port 18 is formed in a ring shape along the opening edge of the opening portion 13a of the main body case 13 (also referred to as the peripheral edge of the main body case side protrusion 17A). The size of the air inlet 18 is preferably such that it will not be completely blocked by the user's fingers. For example, the size of the air inlet 18 in the main axis direction (Z-axis direction) is preferably equal to or greater than the width of the first knuckle of the average thumb of an average adult (for example, greater than 2.0 cm). In addition, the distance between the two slits extending parallel to the main axis direction of the air intake port 18 in the X-axis direction may be equal to or greater than the width of the first knuckle of an average thumb of an average adult.

In addition, the air intake port 1 may be one or two slits extending parallel to the main axis direction as long as it is of a size not to be blocked by the user's fingers. That is, the air inlet 18 may be formed in a slit shape along the opening edge of the opening 13 a of the main body case 13 .

As shown in FIG. 28, the cover member 17 has the plate part 17B which supports the main body case side protrusion 17A. The plate portion 17B is arranged to overlap the inner side of the main body case 13 . The plate portion 17B is sandwiched between the main body case 13 and the cartridge receiving portion 10 . The cartridge storage part 10 side (−Y side) of the plate part 17B is curved along the peripheral surface of the cartridge storage part 10 . Moreover, the main body case 13 side (+Y side) of the plate part 17B is curved along the inner wall surface of the surrounding wall part 12B (refer FIG. 2). The curved shape (curvature, etc.) of the plate portion 17B is different between the cartridge housing portion 10 side (−Y side) and the main body case 13 side (+Y side).

Further, the main axis direction upper side (+Z) of the main body case 13 side of the plate portion 17B is curved along the inner wall surface of the second corner portion 12C2 of the peripheral wall portion 12B. That is, the thickness of the plate portion 17B decreases toward the upper side (+Z) in the main axis direction. The above-described air holes 19 , air grooves 70 , and case fitting holes 17 b 1 are formed in the plate portion 17B. Two air holes 19 are formed across the main body case side protrusion 17A in the X-axis direction.

Fig. 29 is a sectional view taken along arrow G-G shown in Fig. 3 .

As shown in FIG. 29 , the air hole 19 is arranged at a portion where the cover member 17 and the main body case 13 overlap. That is, the air hole 19 is arranged inside the main body case 13 and is covered by the main body case 13 . Therefore, the air holes 19 cannot be visually recognized from the outside of the main body case 13 . In addition, the air holes 19 cannot be directly blocked with fingers unless the main body case 13 is removed.

The air hole 19 fluidly communicates the air inlet 18 with the interior of the cartridge housing 10 . The air hole 19 is a main flow path of the intake flow path that takes outside air into the interior of the exterior case 12 . The air hole 19 in this embodiment communicates with the air communication hole 10 e formed in the cartridge storage portion 10 , so that the air inlet 18 communicates with the interior of the cartridge storage portion 10 in a short distance. In addition, when the air communication hole 10e is not formed, the air taken from the air hole 19 into the interior of the outer case 12 flows into the interior of the cartridge storage portion 10 through all gaps in the cartridge storage portion 10 .

Returning to FIG. 26 , two case fitting holes 17 b 1 are formed on the plate portion 17B on the upper side and lower side of the air hole 19 , and two sets are formed in the X-axis direction via the main case side protrusion 17A. The claws fit into the main body case 13 in a total of four case fitting holes 17b1. Specifically, fitting claws 13E of the first housing 13A are claw-fitted into two housing fitting holes 17b1 disposed on the +X side of the main body housing-side protrusion 17A (see FIG. 34 described later). In addition, fitting claws 13I of the second housing 13B are claw-fitted into the two housing fitting holes 17b1 disposed on the −X side of the main body housing-side protrusion 17A (see FIG. 35 described later).

The air groove 70 forms a space connecting the air intake port 18 and the air hole 19 . As shown in FIG. 28 , the air groove 70 has an annular groove portion 71 and two stepped groove portions 72 . The annular groove portion 71 is formed in an annular shape around the main body case side protrusion 17A in the plate portion 17B. The annular groove portion 71 is recessed on the −Y side from the outer surface of the plate portion 17B on the main body case 13 side (+Y) side. As shown in FIG. 29 , the width of the annular groove portion 71 is preferably larger than the width of the air intake port 18 (the distance from the inner peripheral edge to the outer peripheral edge).

The two stepped groove portions 72 are formed on the +X side end edge and the −X side end edge of the annular groove portion 71 . The stepped groove portion 72 has a lower bottom surface than the annular groove portion 71 . That is, the stepped groove portion 72 is recessed toward the −Y side relative to the annular groove portion 71 . Air holes 19 are formed in the bottom surface of the stepped groove portion 72 . The bottom surface of the stepped groove portion 72 is formed to be larger than the opening area of the air hole 19 .

As shown in FIG. 27 , the cover member 17 has a cartridge storing portion side protrusion 17C on the cartridge storing portion 10 side (−Y side) of the plate portion 17B. The cartridge storage portion side protrusion 17C is inserted into a through hole 10c formed on the peripheral surface of the cartridge storage portion 10 (see FIG. 18 ). Like the through-hole 10c of the cartridge housing 10, the protrusion 17C on the cartridge housing side is formed in the shape of a long hole extending along the main axis direction (Z-axis direction).

In addition, as shown in FIG. 27 , the cover member 17 has a cover positioning protrusion 17D on the cartridge housing portion 10 side (−Y side) of the plate portion 17B. The cover positioning protrusion 17D is disposed on the -X side of the cartridge housing side protrusion 17C. The cover positioning protrusion 17D is a rectangular protrusion extending in the X-axis direction. The cover positioning protrusion 17D is inserted into the rectangular groove 10c1 of the cartridge housing portion 10 shown in FIG. 18 . As a result, errors in assembly of the cover member 17 with respect to the cartridge housing portion 10 can be prevented.

＜Sensor holder＞

FIG. 30 is a view of the sensor holder 35 according to one embodiment viewed from the radially outer side. FIG. 31 is a view of the sensor holder 35 according to one embodiment viewed from the radially inner side. FIG. 32 is a perspective view of a sensor holder 35 according to one embodiment.

As shown in FIG. 32 , the sensor holder 35 has a curved plate portion 35A having a shape along the peripheral surface of the cartridge housing portion 10 . As shown in FIG. 29 , the curved plate portion 35A is in airtight contact with the peripheral surface of the cartridge housing portion 10 via the adhesive sheet 48 . The curved plate portion 35A is disposed in a narrow gap between the cartridge housing portion 10 and the holder 30 .

As shown in FIG. 29 , on the sensor holder 35 , a holder-side protrusion 35B protruding toward the holder 30 is provided on the outer surface of the curved plate portion 35A opposite to the cartridge housing portion 10 . The holder-side protrusion 35B is formed in a cylindrical shape. The sensor 34 is held inside the holder-side protrusion 35B. The holder-side protrusion 35B (and the sensor 34 ) is arranged to be inserted into the second notch portion 42d2 of the second rib 42D of the holder 30 .

An air flow path 80 connecting the inside of the cartridge housing 10 and the sensor 34 is formed on the holder-side protrusion 35B. The air flow path 80 extends radially from the sensor 34 to the inner wall surface of the curved plate portion 35A. A holding portion 35C holding the sensor 34 is provided on the side of the cartridge housing portion 10 of the air flow path 80 . As shown in FIG. 31 , the holding portions 35C are disposed as a pair on the inner wall surface of the air flow path 80 radially inward of the sensor 34 . The sensor 34 abuts against the holding portion 35C, thereby preventing the sensor 34 from falling into the pod storage portion 10 .

The cartridge storage part 10 side of the sensor 34 becomes a detection part. The detection unit detects, for example, the movement of the diaphragm deformed by pressure fluctuations as a change in capacitance. The detection part is covered with a waterproof air-permeable member 81 . The waterproof and air-permeable member 81 is formed of a material having both waterproof and air-permeable properties.

In this way, the connection method of the fourth connection portion 94 includes claw fitting.

＜Appearance of main unit＞

Fig. 36 is a front view of the main body unit 2 in a state where the mouthpiece 11 of the embodiment is removed.

As shown in FIG. 36 , the main body unit 2 includes a cartridge receiving portion 10 having a cartridge insertion opening 10 a protruding from the outer casing 12 . That is, a part of the cartridge housing portion 10 including the cartridge insertion opening 10 a protrudes from the outer case 12 , and it is easy to visually confirm the position where the cartridge 3 is inserted and removed.

A part of the cartridge housing portion 10 protruding from the outer case 12 includes a mouthpiece connection portion 10B for connecting the mouthpiece 11 to the cartridge insertion opening 10a (see FIGS. 6 and 20 ). That is, at least a part of the mouthpiece connection portion 10B protrudes from the exterior case 12 . Thereby, the first groove portion 10b1 and the like of the mouthpiece connection portion 10B are easily recognized visually from the cartridge insertion opening 10a.

The exterior case 12 is provided with a raised portion 12D on the upper side (+Z side) in the axial direction. The cartridge receiving portion 10 protrudes upward in the main axis direction from the deformation transition portion 12D1 of the raised portion 12D. The deformed transition portion 12D1 is a portion from the second corner portion 12C2 to the top P of the raised portion 12D. The deformation transition portion 12D1 can also be said to be a portion where the dimension of the outer case 12 in the Z-axis direction increases from the second corner portion 12C2 to the top P of the raised portion 12D. In addition, the deformation transition portion 12D1 can also be said to be a portion inclined with respect to the main axis direction. In addition, the deformed transition portion 12D1 is not limited to a curved surface as shown in FIG. 36, but may be a slope.

By deforming the transition portion 12D1 , a portion largely exposed from the exterior case 12 (+Y side) and a portion slightly exposed (−Y side) are formed in the cartridge housing portion 10 . Visibility of the pod storage portion 10 can be ensured at the relatively exposed portion of the pod storage portion 10 . In the small exposed portion of the cartridge storage portion 10 , the outer casing 12 can ensure an area for protecting the cartridge storage portion 10 . In addition, since the contact length between the edge of the outer case 12 and the peripheral surface of the cartridge housing portion 10 becomes longer, it is easy to secure connection strength when both are bonded.

As shown in FIG. 36 , the pod insertion opening 10a is disposed below the top P of the protruding portion 12D in the main axis direction (Z-axis direction) in which the pod storage portion 10 extends. That is, the cartridge insertion opening 10 a descends toward the lower side (−Z side) in the main axis direction with respect to the top P of the raised portion 12D. For example, when the main body unit 2 falls upside down, etc., the raised portion 12D contacts the ground prior to the cartridge insertion opening 10 a to protect the cartridge insertion opening 10 a.

The raised portion 12D has a deformed transition portion 12D2 on which the input device 15 is disposed on the opposite side (−Y side) to the deformed transition portion 12D1 across the top P. The input device 15 is disposed at a position below the top P of the raised portion 12D in the main axis direction (Z-axis direction) in which the cartridge housing portion 10 extends. For example, when the main body unit 2 is dropped upside down, the raised portion 12D comes into contact with the ground or the like prior to the input device 15 to prevent malfunction of the input device 15 .

The input device 15 is disposed facing an acute angle direction with respect to the main axis O of the cartridge receiving portion 10 passing through the center of the cartridge insertion opening 10a. Specifically, the angle θ at which the main axis O intersects the diagonal line O1 connecting the first corner portion 12C1 (input device 15 ) and the third corner portion 12C3 is smaller than 90°. According to this configuration, the user can easily put his fingers on the input device 15 while gripping the mouthpiece 11 attached to the cartridge insertion opening 10a.

The main body unit 2 is provided with a movement restricting member (cover member 17 , sensor holder 35 ) that restricts the movement of the cartridge housing 10 as a measure for drawing out the cartridge housing 10 that partially protrudes from the exterior case 12 . The movement restricting member at least restricts the movement of the cartridge storage portion 10 in the pulling-out direction from the outer case 12 . Here, the "extraction direction" means a direction toward the upper side (+Z side) in the main axis direction (Z-axis direction).

As shown in FIG. 6, the exterior case 12 has the main body case 13 in which the opening part 13a was formed. The cover member 17 (movement restricting member) has a main body case side protrusion 17A inserted into the opening 13a. The main body case side protrusion 17A is locked to the outer case 12 at least in the pull-out direction, and restricts the movement of the pod storage portion 10 .

In addition, the cover member 17 has a cartridge storage portion side protrusion 17C inserted into the through hole 10 c of the cartridge storage portion 10 . Even if the side protrusion 17C of the cartridge storage part is pulled out by the user and causes the adhesion and peeling of the cover member 17 with respect to the peripheral surface of the cartridge storage part 10, it is hooked on the cartridge storage part 10 to prevent the cartridge from being stored. part 10 from the exterior case 12.

In addition, the cover member 17 has a plate portion 17B interposed between the cartridge housing portion 10 and the exterior case 12 . The thickness of the plate portion 17B decreases toward the pulling-out direction of the cartridge housing portion 10 (see FIG. 28 ). The plate part 17B is inserted into the wedge-shaped space between the cartridge storage part 10 and the outer casing 12 (in detail, the rounded inner wall surface of the second corner part 12C2 of the outer casing 12 gradually approaches the edge of the cartridge storage part 10 surrounding space). That is, the plate portion 17B serves as a wedge, preventing the cartridge storage portion 10 from being pulled out from the outer case 12 .

As shown in FIG. 29 , in the holder 30 fixed to the exterior case 12 , a second notch 42 d 2 is formed in the second rib 42D. The sensor holder 35 (movement limiting member) has a holder-side protrusion 35B inserted into the second notch portion 42d2. The holder-side protrusion 35B is locked to the holder 30 at least in the pull-out direction, and restricts the movement of the pod storage portion 10 .

In addition, the sensor holder 35 has a cartridge storage portion side protrusion 35D inserted into the through hole 10 d of the cartridge storage portion 10 . Even if the side protrusion 35D of the cartridge storage part is pulled out by the user and causes the sensor holder 35 to peel off from the surrounding surface of the cartridge storage part 10, it will be hooked on the cartridge storage part 10 to prevent the smoke from being released. The bullet storage unit 10 is pulled out from the exterior case 12 .

＜How to assemble the extractor＞

FIG. 37 is an explanatory diagram showing a situation in which a pod 3 is stored in the pod storage unit 10 according to one embodiment. FIG. 38 is an explanatory view showing a state in which the mouthpiece 11 is attached to the pod housing 10 according to the embodiment.

As shown in FIG. 37 , when the inhaler 1 is assembled, the cartridge 3 is accommodated in the cartridge housing portion 10 of the main unit 2 . As shown in FIG. 5 , the cartridge 3 is inserted through the cartridge insertion opening 10 a of the cartridge housing portion 10 protruding from the exterior case 12 with the planar electrode 26 h facing the main unit 2 side.

The pod 3 is shorter than the pod receiving portion 10, so it falls freely when inserted. At this time, around the pod 3, there is no component that hinders the movement of the pod 3 in the direction of rotation, and the pod 3 also falls with a corresponding momentum, so even if the engagement protrusion 43h of the positioning mechanism 90 and the pod When the circumferential positions of the engagement grooves 26i of the cartridge 3 are inconsistent, the cartridge 3 can be bounced and rotated by colliding with the engagement protrusion 43h, or the cartridge 3 can be rotated along the curved surface of the engagement protrusion 43h. It slides down so that the engagement protrusion 43h enters the engagement groove portion 26i.

Here, in this embodiment, the gap generated between the inner diameter D1 of the cartridge housing portion 10 and the outer diameter D2 of the cartridge 3 is greater than 2.6% of the inner diameter of the cartridge housing portion 10 . Therefore, the gap between the pod storage portion 10 and the pod 3 is relatively large, and it is easy to introduce the engaging protrusion 43h into the engaging groove 26i. That is, when the pod 3 is inserted, even if the circumferential positions of the engaging protrusion 43h and the engaging groove 26i do not match, the pod 3 is assembled in a normal position. Thus, the planar electrode 26h of the cartridge 3 is in contact with the protruding electrode 50 .

In addition, when the above-mentioned cartridge 3 is inserted, sometimes the cartridge 3 is not assembled in a regular position. In this case, the pod 3 is in a state of climbing on the engaging protrusion 43h (hereinafter, simply referred to as "climbing state"). In the climbing state of the pod 3 , the movement of the pod 3 in the direction of the lower side (-Z side) of the main axis is restricted. Therefore, the planar electrode 26h is separated from the protruding electrode 50 in the main axis direction, and the conduction between the cartridge 3 and the main body unit 2 cannot be ensured.

If the suction port 11 is mounted on the cartridge receiving portion 10 in the climbing state of the cartridge 3 , the cartridge abutting portion 60 abuts against the cartridge 3 before the installation of the cartridge 11 is completed. Specifically, when the protruding portion 11b1 of the mouthpiece 11 passes through the first groove portion 10b1 or the second groove portion 10b2 of the mouthpiece connection portion 10B, the cartridge abutting portion 60 abuts against the cartridge 3 . Then, the cartridge abutting portion 60 is compressed in the main axis direction, and the cartridge 3 is pressed against the engagement protrusion 43h. The engagement protrusion 43h has a curved shape, so even if the center of the engagement protrusion 43h does not coincide with the circumferential position of the center of the engagement groove 26i, as long as the engagement groove 26i is engaged with the front end of the engagement protrusion 43h, the smoke will The pod 3 slides obliquely along the curved surface of the engaging protrusion 43h, and the pod 3 is assembled in a regular position.

Moreover, when the above-mentioned cartridge 3 is pressed so that the cartridge 3 is still in the climbing state, as shown in FIG. . Therefore, during the period when the protruding portion 11b1 passes through the third groove portion 10b3 of the mouthpiece connecting portion 10B, the cartridge 3 rotates together. The cartridge 3 is rotated by the frictional force generated between the contact portion 60 and the cartridge. If the front end (apex) of the engagement protrusion 43h is opposed to the engagement groove 26i by the rotation of the cartridge 3, the cartridge 3 slides down along the curved surface of the engagement protrusion 43h, and the engagement protrusion 43h enters the engagement groove. within section 26i. As described above, in this embodiment, the cartridge 3 can be assembled in a normal position in three stages of free falling of the cartridge 3 , pressing of the cartridge 3 , and rotation of the cartridge 3 .

When the mouthpiece 11 is rotated to the end and the mouthpiece 11 is installed in the pod storage portion 10, the pod abutting portion 60 becomes compressed in the main axis direction, the planar electrode 26h is pressed against the protruding electrode 50, and Bullet 3 is positioned. In this way, through the installation of the mouthpiece 11 , the positioning of the cartridge 3 and further the electrical conduction between the cartridge 3 and the main unit 2 are performed. In addition, the annular protrusion 61 of the pod abutting portion 60 is compressed in the main axis direction, thereby sealing the gap between the pod 3 and the mouthpiece 11 .

Through the above, the assembly of the aspirator 1 is completed. In addition, as shown in Fig. 37 and Fig. 38, the fragrance source container 4 can also be inserted into the mouthpiece 11 in advance, but in this case, after the mouthpiece 11 is installed on the pod storage portion 10, insert the mouthpiece 11 The aroma source container 4 is inserted, thus completing the assembly of the inhaler 1 .

＜How to use the extractor＞

When using the inhaler 1 described above, the user first presses the input device 15 shown in FIG. 1 . At this time, it is also possible to program, for example, that the main body unit 2 is activated by pressing the input device 15 several times.

Next, the user inhales while holding the mouthpiece 11 or the flavor source container 4 . Then, the air inside the pod storage portion 10 flows, and the sensor 34 shown in FIG. 29 senses the puff. If the sensor 34 senses the puff, the heating wire 25b of the cartridge 3 shown in FIG. 6 is energized, and the heating wire 25b generates heat. When the heating wire 25b generates heat, the liquid aerosol source impregnated in the die 25a is heated and atomized. The atomized aerosol is sucked up together with the air (external air) taken in by inhalation.

As shown in FIG. 29 , air (outside air) is taken in from the air intake port 18 in the gap between the main body case 13 and the cover member 17 . The air obtained from the air inlet 18 flows into the inside of the pod housing 10 through the annular groove 71 , the stepped groove 72 , the air hole 19 , and the air communication hole 10 e of the air groove 70 . The air flowing into the pod housing 10 flows into the atomizing chamber 24c through the air inlet 26c and the opening 24e of the pod 3 as shown in FIG. 6 .

The atomized aerosol fills the atomizing chamber 24c, and together with the air flowing into the atomizing chamber 24c, is sucked to the mouthpiece 11 side through the flow pipe 21c, the through hole 21b, and the communication hole 62 of the pod abutting portion 60. Afterwards, the mixed gas of the atomized aerosol and air enters the user's mouth through the flavor source container 4 installed in the mouthpiece 11 . Thereby, the user can taste the fragrance.
