Detailed Description
Further advantages and effects of the present invention will become apparent to those skilled in the art from the disclosure of the present specification, by describing the embodiments of the present invention with specific examples. While the description of the invention will be described in connection with the preferred embodiments, it is not intended to limit the inventive features to the implementation. Rather, the purpose of the invention described in connection with the embodiments is to cover other alternatives or modifications, which may be extended by the claims based on the invention. The following description contains many specific details for the purpose of providing a thorough understanding of the present invention. The invention may be practiced without these specific details. Furthermore, some specific details are omitted from the description in order to avoid obscuring the invention. It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.
Referring to fig. 1 to 3, the present invention provides an aerosol-generating device 1 comprising an inner housing 10, a holder 20 and a heating body 11, wherein the holder 20 is provided on a body 30 of the aerosol-generating device 1, and the heating body 11 is adapted to be inserted into an aerosol-forming substrate (not shown) placed in the inner housing 10. Referring to fig. 3 and 4, a transition piece 40 is provided between the inner case 10 and the bracket 20, and the inner case 10 is rotatably connected to the bracket 20 between a first position and a second position through the transition piece 40, and the aerosol-forming substrate and the heating body 11 are capable of relative movement in a circumferential direction (shown in a Z direction in fig. 1 and 2) during a process from the first position to the second position. In both the first and second positions, the aerosol-forming substrate is in contact with the heating body 11.
When the user sucks, an aerosol-forming substrate is placed in the inner case 10, and the heating body 11 is inserted into the aerosol-forming substrate. At this time, the aerosol-forming substrate is brought into contact with the heating body 11, and the heating body 11 is controlled to heat the aerosol-forming substrate to generate aerosol for the user to suck. When the user completes the suction, the inner housing 10 is controlled to be rotationally shifted from the first position to the second position circumferentially with respect to the holder 20 before the aerosol-forming substrate is pulled out. Since the inner casing 10 is rotated with respect to the bracket 20 in the circumferential direction by the transition piece 40, the connection between the inner casing 10 and the bracket 20 is optimized, the rotating feel of the inner casing 10 is good, and the rotating effect of the inner casing 10 is optimized.
This is favorable to aerosol-forming substrate and heating member 11 to become loose from the adhesion, and after aerosol-forming substrate rotates enough distance along circumference along with inner shell 10 in step, namely aerosol-forming substrate is after enough distance is moved in circumference relative heating member 11 to the aerosol-forming substrate, when the aerosol-forming substrate is pulled out from heating member 11 along the axial again, the quantity of remaining aerosol-forming substrate on heating member 11 can be less, more is favorable to the cleanness of user to aerosol-generating device 1.
In the embodiment of the present invention, the inner housing 10 is rotationally switched from the first position to the second position relative to the aerosol-generating device 1 in the circumferential direction (shown in the Z direction in fig. 1 and 2), and the inner housing 10 may be rotated clockwise in the circumferential direction, rotated counterclockwise, or rotated alternately clockwise and counterclockwise. During the course of the inner housing 10 from the first position to the second position, the aerosol-forming substrate is in contact with the heating body 11 and remains connected, and the aerosol-forming substrate and the heating body 11 can be moved relative to each other in the circumferential direction.
In the first position, the aerosol-forming substrate has a first axial position relative to the heating body 11, and in the second position, the aerosol-forming substrate has a second axial position relative to the heating body 11, the first and second axial positions being the same. That is, in both the first position and the second position, the aerosol-forming substrate is in contact with the heating body 11, and there is no relative movement in the axial direction. Preferably, the aerosol-forming substrate moves axially without relative movement to the heating body 11 from the first position to the second position.
In other embodiments, the first axial position and the second axial position are different, and the aerosol-forming substrate is in contact with the heating body 11 during rotation of the inner housing 10 relative to the aerosol-generating device 1, and the aerosol-forming substrate and the heating body 11 can move axially as well as circumferentially, so long as the aerosol-forming substrate and the heating body 11 can move relatively in the circumferential direction during the rotation from the first position to the second position, and the aerosol-forming substrate is in contact with the heating body 11.
In addition, in the present embodiment, the inner housing 10 is rotated in the circumferential direction during the process of switching the inner housing 10 from the first position to the second position, the heating body 11 is kept stationary, and in other embodiments, the heating body 11 is rotated in the circumferential direction, and the inner housing 10 is kept stationary as long as the aerosol-forming substrate and the heating body 11 generate relative movement in the circumferential direction in the second position. When the heating body 11 rotates in the circumferential direction, the heating body 11 may rotate synchronously with the aerosol generating device 1, or the heating body 11 may rotate, and the aerosol generating device 1 where the heating body 11 is located may remain stationary.
In addition, the specific type of the aerosol-forming substrate of the present invention is not limited as long as it can generate aerosol for the user to suck after being heated by the heating body 11. The heating body 11 heats the aerosol-forming substrate while the aerosol-forming substrate is heated but not combusted. For example, in this embodiment, the aerosol-forming substrate is a solid aerosol-forming substrate comprising the tobacco component, the aerosol-forming substrate being surrounded by an overwrap (e.g., an aluminum foil layer).
In addition, the specific shape of the heating body 11 is not limited, and the heating body 11 in this embodiment is columnar and has a circular cross section. In other embodiments, the cross section of the heating body 11 may be quadrangular, triangular or polygonal. As the number of sides of the cross section of the heating body 11 is larger, the heating body 11 and the aerosol-forming substrate are more easily loosened in the process of generating relative motion in the circumferential direction, and when the aerosol-forming substrate is pulled out of the heating body 11, the amount of the aerosol-forming substrate remained on the heating body 11 is smaller, so that the aerosol-generating device 1 is more convenient for a user to clean.
The specific material of the heating body 11 is not limited as long as it can generate heat after being energized to heat the aerosol-forming substrate to generate aerosol. For example, in the present embodiment, the material of the heating body 11 includes ceramic.
In this embodiment, the transition piece 40 is disposed circumferentially around the inner casing 10. For example, the transition piece 40 is circumferentially disposed 360 around the inner casing 10.
Referring to fig. 1 and 3, in the present embodiment, the transition piece 40 is a rolling piece. The type of rolling element is not limited, and in this embodiment, the rolling element is a bearing. An inner ring 41 of the bearing is connected with the inner shell 10, an outer ring 42 of the bearing is connected with the bracket 20, and balls 43 are arranged between the inner ring 41 and the outer ring 42. In other embodiments, other types of rolling elements are possible, such as balls, with balls replacing the bearings, and the bracket 20 and the inner housing 10 are connected by balls. In the present embodiment, the number of bearings is not limited. By arranging the bearing, on one hand, the connection between the inner shell 10 and the support 20 is optimized, and the rotation effect is optimized, on the other hand, the connection stability of the inner shell 10 and the support 20 can be improved, the axial offset of the inner shell 10 can be reduced, the inner shell 10 is prevented from shaking in the radial direction, the installation precision can be reduced, and in addition, the rolling contact can reduce the abrasion between the inner shell 10 and the support 20 due to the bearing.
In this embodiment, the portion of the inner shell 10 facing the body has an axial extension 11, the bracket 20 has a radial boss 21, the transition piece 40 is placed on the radial boss 21, and the axial extension 11 of the inner shell 10 and the bracket 20 sandwich the transition piece 40 in the radial direction. Preferably, and in the radial direction, the axial extension 11 of the inner shell 10, the outer shell 50, described below, and the bracket 20 sandwich the transition piece 40.
In other embodiments, referring to fig. 2 and 4, the transition piece 40 is a damping piece. The damping member is present, so that the damping hand feeling is generated during the rotation of the inner shell 10 from the first position to the second position in the circumferential direction. Then, when the inner casing 10 can be rotated to any position in the circumferential direction, the inner casing 10 can be held stationary at that position when a circumferential force is applied. When the rotation needs to be continued, circumferential force is applied again. And on the other hand, the connection stability of the inner shell 10 and the support 20 can be improved, the axial offset of the inner shell 10 is reduced, and the inner shell 10 is prevented from shaking in the radial direction.
The damping member of the present invention is not limited in type, and damping materials are classified into 6 types, ① rubber and plastic damping plate, which are used as sandwich layer materials, according to characteristics. The polyurethane is prepared from butyl, acrylic ester, polysulfide, butyronitrile, silicone rubber, polyurethane, polyvinyl chloride, epoxy resin and the like. The material can meet the use requirement within the range of-50 ℃ to 200 ℃. ② Rubber and foam plastics are used as damping sound absorbing materials. The purpose of sound absorption is achieved by using more butyl rubber and polyurethane foam in a mode of controlling the size of cells, through holes or closed holes and the like. ③ Damping composite material for vibration and noise control. The first two kinds of materials are used as damping sandwich layer, and then combined with metal or non-metal structural material to form various sandwich structure plates, beams and other sectional materials, and the sectional materials are machined to produce various structural members. ④ High damping alloy, damping performance is substantially stable over a wide temperature and frequency range. Copper-zinc-aluminum alloys, iron-chromium-molybdenum alloys and manganese-copper alloys are used in many cases. ⑤ The damping paint is prepared with polymer resin, stuffing and supplementary material and may be painted onto the surface of various metal plate structure and has vibration damping, heat insulating and certain sealing performance. Including constrained damping coatings and aqueous damping coatings. ⑥ The high molecular vibration absorbing material can convert mechanical vibration energy or sound energy into heat energy to dissipate and prevent or reduce the damage of mechanical vibration to the parts. The high polymer material has one glass-to-high elastic transition region, and features that the shearing modulus of the high polymer is lowered by about three orders of magnitude and the internal consumption is raised to produce peak. The damping properties of the polymer therefore only have a maximum in the glass transition region. This means that this region is the optimal temperature region for the polymer to be used as damping material. The glass transition temperature of the polymer is also related to the frequency of the external force. Therefore, a proper polymer is selected as the vibration absorbing and damping material according to the requirements of vibration frequency and use temperature.
In other embodiments, referring to FIGS. 5 and 6, the transition piece 40 is an elastic piece, and the elastic piece includes a plurality of first protrusions 44, the plurality of first protrusions 44 are circumferentially spaced apart on the inner shell 10 (shown in the Z-direction in FIG. 6), and a plurality of first grooves 45, the plurality of first grooves 45 are circumferentially spaced apart on the support 20, and the first grooves 45 are matched with the first protrusions 44. In other embodiments, the plurality of first protrusions 44 are circumferentially spaced apart on the support 20, the plurality of first grooves 45 are circumferentially spaced apart on the inner shell 10, and the first grooves 45 cooperate with the first protrusions 44.
Preferably, the first protrusion 44 and the first groove 45 extend in the axial direction, respectively. Then, when the first protrusion 44 contacts with the first groove 45 during the rotation of the inner shell 10 in the circumferential direction, for example, the height of the first protrusion is between 0.1mm and 0.3mm, including between 0.1mm and 0.3mm, the first groove 45 will limit and generate a resistance, and the circumferential force applied to the inner shell 10 overcomes the resistance when the inner shell 10 continues to rotate due to the elastic material. When the first protrusions 44 and the first grooves 45 come into contact again, the first grooves 45 again generate resistance, so that the inner case 10 has periodic resistance during the circumferential rotation.
The arrangement optimizes the connection between the inner shell 10 and the support 20 and optimizes the rotation effect, and improves the connection stability between the inner shell 10 and the support 20, reduces the offset of the inner shell 10 in the axial direction, and prevents the inner shell 10 from shaking in the radial direction.

Thus, the aerosol-forming substrate is subjected to radial compressive forces when placed in the region surrounded by the plurality of second projections 12. In this embodiment, the second protrusions 12 extend in the axial direction, so that the second protrusions 12 are provided to better sandwich the aerosol-forming substrate.

The third protrusion 51 is provided in the first groove 45 so that the inner case 10 can be rotated in synchronization with the outer case 50 in the circumferential direction during the synchronous rotation of the inner case 10 from the first position to the second position.
