The atomizer 1 is used for atomizing atomized liquid into aerosol after being electrified and outputting the aerosol for a user to inhale. In this embodiment, the electronic atomizing device is substantially rectangular and columnar. It will be appreciated that in other embodiments, the electronic atomizing device is not limited to being rectangular, but may be cylindrical, oval, flat, etc.

As shown in fig. 2-3, the reservoir unit 3 may be removably disposed in the housing 21 of the main unit 2 for replacement after the use of the atomized liquid.

The buffer chamber 110 has a smaller liquid storage capacity, and is mainly used for guiding the atomized liquid from the liquid supply pipe 25 to the atomization core 17, and the atomized liquid is heated and atomized by the atomization core 17. In this embodiment, the atomizing chamber 113 is cylindrical and may be formed in the middle of the atomizing housing 11, two buffer chambers 110 are respectively located at two opposite sides of the atomizing chamber 113 in the circumferential direction, and the two buffer chambers 110 may be respectively formed at two sides of the atomizing housing 11 along the length direction, and the two buffer chambers 110 are respectively in one-to-one correspondence with the two liquid supply pipes 25. Each of the buffer chambers 110 may include a first buffer chamber 111 at a lower portion and communicating with the liquid supply pipe 25, and a second buffer chamber 112 at an upper portion and communicating with the first buffer chamber 111.

In this embodiment, the cross-sectional shape of the first buffer cavity 111 is narrow and long, the cross-sectional area of the first buffer cavity 111 is smaller, and when the atomized liquid volume changes, the liquid level change is more obvious, and the liquid level detection is more sensitive. The cross-sectional area of the second buffer cavity 112 is larger, so that more atomized liquid can be buffered, and leakage of the atomized liquid from the pressure release hole 1771 and other parts caused by excessive liquid supply is avoided. The first liquid outlet 114 may be in communication with the bottom of the first buffer cavity 111. In other embodiments, the buffer chamber 110 may be provided with only one and located at one circumferential side of the atomizing chamber 113, or the buffer chamber 110 may be provided with only one and located around the atomizing chamber 113.

The suction nozzle cover 12 is arranged at the upper end opening of the atomization shell 11 to seal and cover the buffer cavity 110. An air outlet channel 120 is formed in the mouthpiece cover 12 for outputting aerosol for inhalation by a user. The mouthpiece cover 12 may include a mouthpiece portion 121 and a sealing portion 122 in some embodiments. The suction nozzle 121 is covered on the atomizing housing 11, and may be made of hard material such as plastic. The air outlet passage 120 may longitudinally penetrate the nozzle portion 121 and may be disposed coaxially with the nozzle portion 121. The sealing part 122 is embedded in the suction part 121, and may be made of soft material such as silica gel, for sealing the upper ends of the two buffer chambers 110.

The atomizing core 17 is disposed in the atomizing chamber 113 and is in fluid communication with the buffer chamber 110. The atomizing core 17 may include a liquid absorbing member 171 for absorbing the atomized liquid from the buffer chamber 110, a heat generating member 172 disposed on the liquid absorbing member 171, and two electrode leads 173 electrically connected to the positive and negative electrodes of the heat generating member 172, respectively. The liquid absorbing member 171 is a porous structure, which may be liquid absorbing cotton, for storing the atomized liquid and supplying the heating member 172 for heating and atomizing. In other embodiments, the liquid absorbing member 171 may be a sintered porous structure, which may be made of a hard capillary structure such as porous ceramics, porous glass, or the like.

The inner wall surface of the liquid absorbing member 171 defines a heat generating chamber 1710, and the heat generating chamber 1710 communicates with the air intake hole 210 for achieving mixing of aerosol and air. The heat generating member 172 may be a cylindrical metal heat generating sheet and may be provided on an inner wall surface of the liquid absorbing member 171, and may heat and atomize the atomized liquid absorbed in the liquid absorbing member 171 after the energization to generate aerosol. The liquid absorbing member 171 wraps the heat generating member 172, so that atomization can be more uniform. It is understood that in other embodiments, the heat generating element 172 may not be limited to a heat generating sheet, for example, it may be a heat generating wire or a heat generating film, and the shape of the heat generating element 172 is not limited to a cylinder, for example, it may be a spiral shape or a mesh shape. In other embodiments, heat-generating component 172 may also be disposed on the outer surface of liquid-absorbing component 171.

In some embodiments, the atomizing core 17 may further include a fixing tube 175 sleeved outside the liquid absorbing member 171, and an atomizing base 174 embedded in the opening at the lower end of the fixing tube 175. The fixing tube 175 may have a circular tube shape and be made of a hard material such as metal, plastic, etc. for supporting the fixing liquid absorbing member 171. The fixed tube 175 is provided with at least one liquid inlet 1750 for conducting liquid between the liquid absorbing member 171 and the buffer chamber 110. In this embodiment, there are three liquid inlets 1750, and the three liquid inlets 1750 may be distributed at intervals along the circumferential direction of the fixed pipe 175. Further, the fixing tube 175 may further be formed with a slot 1751, and the slot 1751 may be formed by extending the upper end surface of the fixing tube 175 downward in the axial direction, so that the upper end opening of the fixing tube 175 has a certain elasticity, and the liquid absorbing member 171 may be conveniently inserted into the fixing tube 175 from the upper end opening of the fixing tube 175. In addition, the slot 1751 may also be used to place the wicking element 171 in fluid communication with the buffer chamber 110, and the slot 1751 and the three fluid intake holes 1750 may be evenly spaced apart along the circumference of the stationary tube 175.

The atomizing seat 174 is embedded in the opening at the lower end of the fixed tube 175, and the outer wall surface of the atomizing seat 174 is in sealing fit with the inner wall surface of the fixed tube 175. In some embodiments, the atomizing base 174 may be made of a soft material such as silicone. The atomizing base 174 may be formed with an air vent 1740 for communicating the heat generating chamber 1710 with the air inlet 210 and two lead holes 1741 for passing the two electrode leads 173 therethrough, respectively, in a longitudinal direction.

In some embodiments, the atomizing core 17 may further include a liquid guide 176 that is sleeved outside the fixed tube 175. The liquid guide member 176 is cylindrical and sleeved between the vent pipe 177 and the fixed pipe 175, and the outer wall surface and the inner wall surface of the liquid guide member are respectively contacted with the vent pipe 177 and the fixed pipe 175, so that the atomized liquid entering from the vent pipe 177 can be rapidly and uniformly conducted to the fixed pipe 175 through the infiltration and capillary effect of the micropores in the liquid guide member 176. The liquid guide 176 may be a porous structure, and may be liquid-guiding cotton, or may be a hard porous structure such as porous ceramic, porous glass ceramic, or porous glass in other embodiments.

The vent tube 177 may include a first tube segment 1772 at a lower portion and a second tube segment 1773 at an upper portion, and the first tube segment 1772 may have an inner diameter and an outer diameter that are greater than the inner diameter and the outer diameter of the second tube segment 1773, respectively. The fixed tube 175, the liquid guide 176, and the liquid suction member 171 can all be accommodated in the first tube section 1772. At least one liquid guiding hole 1770 is formed on the first pipe section 1772, so that atomized liquid in the buffer cavity 110 can enter the breather pipe 177 through the at least one liquid guiding hole 1770 and be absorbed by the liquid guiding member 176. In this embodiment, the number of the liquid guiding holes 1770 is four, the four liquid guiding holes 1770 can be uniformly distributed at intervals along the circumference of the first pipe segment 1772, and the four liquid guiding holes 1770 can be respectively in one-to-one correspondence with the slots 1751 and the three liquid inlet holes 1750.

The upper end of the second tube segment 1773 may be embedded in the outlet channel 120 and communicate with the outlet channel 120. The wall surface of the second pipe section 1773 may further be provided with at least one pressure relief hole 1771, and the buffer cavity 110 may be communicated with the outside through the pressure relief hole 1771, so as to implement pressure relief when the liquid supply pipe 25 supplies liquid to the buffer cavity 110, so that the liquid supply is smooth. In this embodiment, two liquid supply pipes 25 are respectively disposed at two circumferential sides of the vent pipe 177, the at least one pressure relief hole 1771 may be disposed at one side or two sides of the second pipe section 1773, for example, the at least one pressure relief hole 1771 may be disposed at one side of the second pipe section 1773 corresponding to one of the liquid supply pipes 25, or at least one pressure relief hole 1771 may be disposed at two circumferential sides of the second pipe section 1773 corresponding to the two liquid supply pipes 25. In other embodiments, when the number of the liquid supply pipes 25 is one and disposed at one circumferential side of the ventilation pipe 177, the at least one pressure relief hole 1771 may be opened at a side of the second pipe section 1773 corresponding to the one liquid supply pipe 25.

The pressure relief hole 1771 has a small cross-sectional dimension (e.g., aperture, length, width, or cross-sectional area, etc.) so as to create a surface tension that, due to the surface tension, the atomized liquid does not enter the vent tube 177 from the buffer chamber 110. It will be appreciated that the smaller the cross-sectional size of the relief hole 1771, the higher the cost of the opening. In general, the cross-sectional dimensions of the relief vent 1771 may be selected based on factors such as the material of the vent tube 177, the viscosity of the atomized liquid, the cost of the vent, etc. For example, when the viscosity of the atomized liquid is large, the cross-sectional size of the relief hole 1771 may be appropriately increased, and when the viscosity of the liquid is small, the cross-sectional size of the relief hole 1771 may be appropriately decreased. In this embodiment, the pressure relief hole 1771 is a circular hole, the aperture Φ of the pressure relief hole 1771 may be between 0.4 and 1.0mm, preferably between 0.6 and 0.8mm, and in this size interval, the pressure relief hole 1771 has good ventilation and liquid resistance, and the cost of opening the hole is moderate. In other embodiments, the pressure relief hole 1771 may be an oval hole, a square hole, or other shapes, and the length or width of the pressure relief hole 1771 may be between 0.4 mm and 1.0mm, preferably between 0.6 mm and 0.8mm.

The pressure relief hole 1771 is located higher than the atomizing core 17 to reduce leakage. Further, the pressure relief hole 1771 is located higher than the second buffer chamber 112, so that the leakage preventing effect is better. In other embodiments, the pressure relief hole 1771 may be located flush with the upper end surface of the atomizing core 17 or the upper end surface of the second buffer chamber 112. The atomization shell 11 may further be formed with a second liquid outlet 115 communicated with the second buffer cavity 112, and a pressure release channel 1774 for communicating the second buffer cavity 112 with the pressure release hole 1771 may be formed between the outer wall surface of the second pipe section 1773 and the inner wall surface of the atomization shell 11 and between the outer wall surface of the atomization shell 12, and the second buffer cavity 112 is sequentially communicated with the outside through the second liquid outlet 115, the pressure release channel 1774, the pressure release hole 1771, and the air outlet channel 120.

Further, the atomizer 1 may further include a liquid accumulation member 178 sleeved outside the first pipe section 1772. The effusion cell 178 is porous and stores a certain amount of atomized liquid, which in this embodiment may be liquid cotton. In other embodiments, the effusion cell 178 may have a hard porous structure such as porous ceramic, porous glass ceramic, or porous glass. The effusion cell 178 may rapidly and uniformly introduce the atomized liquid in the buffer chamber 110 into the first tube segment 1772 through the infiltration and capillary effect of the pores therein.

In addition, the lower end of the effusion member 178 may be communicated with the first buffer cavity 111 through the first liquid outlet 114, and the upper end of the effusion member 178 may be communicated with the second buffer cavity 112 through the second liquid outlet 115, so that the effusion member 178 may adsorb the atomized liquid in the second buffer cavity 112, and prevent the atomized liquid in the second buffer cavity 112 in a free state from leaking.

The base component 13 is embedded in the lower end opening of the atomization shell 11, and the atomizer 1 can be mounted on the host machine 2 through the base component 13. After the atomizer 1 is assembled with the main unit 2, an air flow gap 280 communicating with the air inlet hole 210 may be formed between the bottom surface of the base member 13 and the upper end surface of the bracket member 28. The base assembly 13 may have at least one fluid supply channel 1320 that communicates the at least one fluid supply tube 25 with the at least one first buffer chamber 111 and at least one vent 1310 that communicates the air flow gap 280 with the heat generating chamber 1710. In the present embodiment, two liquid supply passages 1320 are provided and are respectively located at both sides of the base member 13 in the longitudinal direction, and the upper ends of the two liquid supply pipes 25 are respectively inserted into the two liquid supply passages 1320.

In some embodiments, the base assembly 13 may include a base 131 and a sealing seat 132 sleeved on an upper end of the base 131. The base 131 may be made of hard materials such as plastic. The vent 1310 may be formed on the base 131 in the longitudinal direction. In the present embodiment, there are two ventilation holes 1310 and may be respectively located at both sides of the base 131 in the width direction. The upper end surface of the vent hole 1310 may be higher than the surface of the base 131 of the circumference thereof, so that leakage of liquid through the vent hole 1310 may be reduced.

The sealing seat 132 may be made of soft material such as silica gel. The outer surface of the sealing seat 132 is in sealing engagement with the inner surface of the atomizing housing 11 to avoid leakage. The liquid supply channel 1320 may be formed on the sealing seat 132, and after the liquid supply pipe 25 is inserted into the liquid supply channel 1320, the soft sealing seat 132 wraps the liquid supply pipe 25, so that leakage of liquid can be reduced. In addition, a first blocking wall 1321 may be formed in the liquid supply channel 1320, the first blocking wall 1321 may be located at the bottom of the liquid supply channel 1320 and may be in a concave circular arc shape, a slot in a shape of a straight slot is formed on the first blocking wall 1321, when the atomizer 1 is inserted into the host 2, the liquid supply pipe 25 may pass through the slot on the first blocking wall 1321 to be communicated with the first buffer cavity 111, and after the atomizer 1 is pulled out from the host 2, the slot on the first blocking wall 1321 is closed and sealed to prevent the atomized liquid in the buffer cavity 110 from flowing out. It is understood that, in other embodiments, the slot formed on the first blocking wall 1321 may be a Y-slot, a cross slot, or other shapes.

The atomizer 1 may in some embodiments further comprise at least one support tube 15 embedded in the at least one liquid supply channel 1320 to communicate the liquid supply tube 25 with the first buffer chamber 111. The support tube 15 is a hard support tube, which may be made of hard materials such as metal. The support pipe 15 is embedded in the upper part of the liquid supply channel 1320, has a short axial length, and is used for supporting the soft liquid supply channel 1320, so that the problems of inconvenient assembly, poor appearance and reduced reliability caused by too long length of the liquid supply pipe 25 can be avoided, or the problem of insufficient support caused by too long length of the soft liquid supply channel 1320 can be avoided. The support tube 15 may not be in direct contact with the liquid supply tube 25, and damage caused by collision of the support tube 15 with the liquid supply tube 25 when the atomizer 1 is assembled with the main unit 2 may be avoided. Specifically, in the present embodiment, a certain interval is formed between the lower end surface of the support tube 15 and the upper end surface of the liquid supply tube 25, and the inner diameter of the support tube 15 may be larger than the outer diameter of the liquid supply tube 25.

The atomizer 1 may further comprise at least one second electrode column 16 longitudinally embedded on the base assembly 13. The upper end of the second electrode column 16 may be in communication with the heat generating cavity 1710 and proximate to the electrode lead 173. Typically, there are two second electrode posts 16, and the two second electrode posts 16 are electrically connected to two electrode leads 173, respectively. When the atomizer 1 is inserted into the main body 2, the lower ends (the ends toward the battery 22) of the two second electrode posts 16 are respectively brought into contact with the upper ends (the ends toward the mouthpiece cover 12) of the two first electrode posts 26. Each second electrode column 16 and the corresponding conductive first electrode column 26 form an electrode assembly 60, and the electrode assembly 60 is preferably an elastic electrode assembly.

Further, the electronic atomizing device may further include a liquid level detection system for detecting whether the atomized liquid in the buffer cavity 110 is sufficient, and the liquid transmission assembly 23 may start or stop supplying the liquid according to the detection result of the liquid level detection system, for example, start supplying the liquid when the detection result is lack of liquid, and stop supplying the liquid when the detection result is presence of liquid. The liquid level detection mode of the liquid level detection system is not limited, and various modes such as capacitance and resistance can be adopted as long as atomized liquid in a free state can be detected.

In this embodiment, the liquid supply tube 25 may be conductive, and may be made of a conductive material such as metal. The upper end of the liquid supply pipe 25 is communicated with the buffer cavity 110, and the lower end is communicated with the liquid transmission assembly 23. The end of the liquid supply tube 25 in communication with the liquid delivery assembly 23 may be electrically connected to the controller 24. The upper end of the electrode assembly 60 is electrically connected to the heat generating member 172, and the lower end is electrically connected to the controller 24. One end of the liquid supply pipe 25 connected with the controller 24 can be used as a detection anode of the liquid level detection system, one end of the electrode assembly 60 connected with the controller 24 can be used as a detection cathode of the liquid level detection system, and naturally, one end of the liquid supply pipe 25 connected with the controller 24 can be used as a detection cathode, and one end of the electrode assembly 60 connected with the controller 24 can be used as a detection anode. If the liquid supply pipe 25 and the heating element 172 are simultaneously contacted with the atomized liquid and conducted by the atomized liquid to form a passage, the controller 24, the liquid supply pipe 25, the atomized liquid in the buffer cavity 110, the heating element 172, the electrode assembly 60 and the controller 24 are sequentially conducted to form a liquid level detection circuit, which means that the atomized liquid in the buffer cavity 110 is sufficient, the liquid transmission assembly 23 can stop supplying the liquid to the buffer cavity 110, so as to avoid the leakage of the atomized liquid caused by excessive atomized liquid in the buffer cavity 110, the atomized liquid is gradually consumed along with the suction and the heating, and the atomized liquid in a free state in the buffer cavity 110 can be immediately supplemented to the effusion element 178, the liquid guide element 176 and the liquid suction element 171 until the interruption. When the gap between the liquid supply pipe 25 and the heating element 172 is open, it indicates that the atomized liquid in the buffer cavity 110 is insufficient, the liquid transmission assembly 23 can be started to supply liquid to the buffer cavity 110, the liquid accumulation member 178, the liquid guide member 176 and the liquid suction member 171 are filled with the supplied atomized liquid, and when a certain amount of atomized liquid in a free state is present in the buffer cavity 110, a passage is formed between the liquid supply pipe 25 and the heating element 172, and the liquid transmission assembly 23 stops supplying liquid.

In this embodiment, whether atomized liquid exists in the buffer cavity 110 is judged by the on-off of the circuit between the liquid supply pipe 25 and the electrode assembly 60, the structure is simple, the result is reliable, the automatic liquid injection response is fast, and dry burning and liquid leakage can be avoided. Specifically, whether a passage is formed between the liquid supply pipe 25 and the electrode assembly 60 is determined by the controller 24, if so, a closing signal for stopping the supply of liquid to the liquid transfer assembly 23 is output to the liquid transfer assembly 23, and if not, an opening signal for opening the liquid transfer assembly 23 is output to the liquid transfer assembly 23. The off signal and/or the on signal may be transmitted to the liquid delivery assembly 23 in real time, so that the liquid delivery assembly 23 stops supplying liquid and/or starts supplying liquid in real time. In other embodiments, the controller 24 may also include a delay module for delaying the start or stop of the liquid delivery assembly 23.

In another embodiment, the liquid level detection system can control the liquid transmission assembly 23 to start liquid supply when the circuit break between the liquid supply pipe 25 and the electrode assembly 60 is detected, and the liquid transmission assembly 23 stops pumping liquid after a certain period of time. The atomized liquid pumped by the liquid delivery assembly 23 can be stored in the liquid accumulation member 178, the liquid guide member 176 and the liquid suction member 171 for heating and atomizing by the heating member 172. When the atomized liquid is consumed, the system will again detect an open circuit between the liquid supply tube 25 and the electrode assembly 60, and then turn on the liquid delivery assembly 23 to continue pumping liquid. The primary pumping time and the pumping liquid amount can be determined according to parameters such as the liquid supply speed, the atomization speed, the capacity of the buffer cavity 110, and the like, for example, the primary pumping time can be 1-5 s, and the primary pumping liquid amount can be 15-50 mg.

The two end surfaces of the liquid supply pipe 25 can conduct electricity, and the liquid supply pipe 25 can be respectively communicated with the atomized liquid in the buffer cavity 110 and the controller 24 through the two end surfaces. The end surfaces of the first electrode column 26 and the second electrode column 16 can be conductive, the lower end surface of the first electrode column 26 is conductive with the controller 24, the upper end surface of the first electrode column 26 can be in contact conductive with the lower end surface of the second electrode column 16, and the upper end surface of the second electrode column 16 is conductive with the heating element 172. Specifically, the outer circumferences of the liquid supply tube 25, the first electrode column 26, and the second electrode column 16 are insulated, and for example, an insulating layer (such as an insulating sleeve, an insulating coating, a silicone flange, or the like) may be wrapped around the outer wall surfaces of the liquid supply tube 25 and/or the first electrode column 26, and/or the second electrode column 16 to insulate the outer circumferences thereof, so that the reliability of the circuit between the liquid supply tube 25 and the electrode assembly 60 can be improved, erroneous judgment of a passage between the liquid supply tube 25 and the electrode assembly 60 due to leakage of liquid can be prevented, and dry burning of the heat generating element 172 can be prevented. Specifically, the liquid supply tube 25 communicates at the upper end with the region other than the buffer chamber 110 and the lower end connection controller 24 and the electrode assembly 60 communicates at the upper end with the region other than the heat generating chamber 1710 and the lower end connection controller 24, and the outer circumferential surface of the liquid supply tube 25 is absolutely insulated from the outer circumferential surface of the electrode assembly 60. In the present embodiment, the outer wall surface of the liquid supply tube 25 is wrapped by the insulating sealing seat 132 and the first sealing sleeve 27, so that the liquid supply tube 25 and the electrode assembly 60 are insulated from each other at a predetermined region.

Further, in order to further improve the reliability of the circuit between the liquid supply pipe 25 and the electrode assembly 60, a disconnection detection module may be further provided to perform disconnection detection on the liquid supply pipe 25 and/or the electrode assembly 60. By detecting the disconnection of the liquid supply pipe 25 itself, the problem of serious liquid leakage due to continuous liquid supply caused by disconnection due to failure of the liquid supply pipe 25 itself can be prevented. By detecting the disconnection of the electrode assembly 60, if the electrode assembly 60 fails to cause the disconnection, it is determined that the second electrode column 16 and the first electrode column 26 are not turned on, and it is determined that the atomizer 1 is not connected to the main unit 2, and the system is not operated. In some embodiments, the open circuit detection may be implemented by a redundant design, for example, at least two parallel wires may be led from the controller 24 to connect to the liquid supply pipe 25, and if the open circuit is caused by failure of the liquid supply pipe 25, the controller 24 outputs a shut-off signal to stop the liquid supply to the liquid delivery assembly 23.

Further, each liquid supply pipe 25 and the electrode assembly 60 at the corresponding side form a liquid level detection circuit, so that double-side liquid level detection of the buffer cavities 110 at two sides is realized, and the inclined use of the electronic atomization device can be considered. In the detection process, if the liquid level detection on both sides is a passage, the liquid transmission assembly 23 stops supplying liquid, if one side of the passage is open, the liquid transmission assembly 23 stops supplying liquid, and if the liquid level detection on both sides is open, the liquid transmission assembly 23 starts supplying liquid. It will be appreciated that in other embodiments, the liquid level detection circuit may be provided on only one side.

It will be appreciated that in other embodiments, the atomizer 1 may be subjected to liquid level detection by other liquid level detection structures, for example, a liquid level detection member may be additionally disposed in the buffer cavity 110 for liquid level detection.

As shown in fig. 10, the liquid level detection circuit in this embodiment includes a MOS tube U1, a resistor R2, a resistor R3, and an operational amplifier Q1.

The controller 24 includes an MCU, an OIL_EN pin of the MCU is connected with a gate of the MOS tube U1, an AD_T pin of the MCU acquires sampling signals output by the operational amplifier Q1 in real time, a VCC pin of the MCU is connected with a power supply anode, and a GND pin of the MCU is grounded. Specifically, the MCU can sample the ad_t pin real-time ADC at a constant sampling frequency, and calculate the resistance Rs of the atomized liquid according to a proportional principle that the voltage ratio is equal to the resistance ratio.
