[0036] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] Please also read Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 It is a schematic structural diagram of an aerosol generating device provided in one embodiment of the utility model; Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure of the aerosol generating device; Figure 3 yes Figure 1 Schematic diagram of the explosion structure of the middle oil storage component and the first sealing component; Figure 4 yes Figure 3 Schematic diagram of the cross-sectional structure of the middle oil storage component and the first sealing component after explosion.

[0038] The aerosol generating device 100 provided in one embodiment of the utility model comprises an atomizing module 10, a sensing component 20 and a battery module 30. The atomizing module 10 comprises an oil storage part 11, an air guide channel 12 and an atomizing component 13. The air guide channel 12 runs through the oil storage part 11. The atomizing component 13 is accommodated in the oil storage part 11. The sensing component 20 is connected to the oil storage part 11. The sensing component 20 comprises a sensing microphone 21 and a first sealing component 22. The first sealing component 22 It includes a sensing chamber 221, in which the sensing microphone 21 is accommodated, the first sealing member 22 is snap-fitted with the oil storage member 11, and the first sealing member 22 and the oil storage member 11 enclose an air gathering chamber 40, the air gathering chamber 40 is connected to the air guide channel 12 and the sensing chamber 221, and the side wall of the air gathering chamber 40 is provided with an air hole 41, which is connected to the air gathering chamber 40 and the outside; the battery module 30 is electrically connected to the sensing microphone 21 and the atomization assembly 13 respectively.

[0039] It should be noted that the oil storage member 11 is a component for storing oil; the air guide channel 12 can be formed by a tubular component, or can be surrounded by the cavity wall of the oil storage member 11; the atomization component 13 is a component that can heat the oil to form smoke; and the first sealing member 22 can be made of silicone material.

[0040] Specifically, the atomization module 10, the sensing component 20 and the battery module 30 are assembled, wherein the oil storage component 11 is engaged with the first sealing component 22 and encloses to form a gas gathering chamber 40. By suctioning the air guide channel 12, the air pressure in the air guide channel 12, the gas gathering chamber 40 and the sensing chamber 221 is reduced, and the external gas enters the gas gathering chamber 40 through the air hole 41 and flows along the gas gathering chamber 40 to the air guide channel 12. The sensing microphone 21 receives the signal of gas flow, and then the atomization component 13 starts to heat the e-liquid to form smoke, and the smoke flows with the flow of external gas. It can be understood that in this solution, it is only necessary to assemble the atomization module 10, the sensing component 20 and the battery module 30 into a semi-finished component to detect whether the normal smoking function can be performed. By testing semi-finished components, defects or faults can be found in time. When a fault occurs during the detection process, the faulty component can be analyzed from the atomization module 10, the sensor component 20 and the battery module 30, so that the defective or faulty components can be repaired or replaced in time, making the detection process simple. Based on the above method, the detection cost of the aerosol generating device 100 is low, which can effectively reduce the product defect rate and improve product quality.

[0041] It should be noted that the battery module 30 includes parts such as a battery, a circuit board and electrical wiring. The battery is electrically connected to the circuit board. The battery is used to provide electrical energy. The circuit board is used to control the circuit. For example, when the induction microphone 21 receives a gas flow signal, the circuit board receives the signal sent by the induction microphone 21 and controls the battery module 30 to power the atomization module 10.

[0042] Optionally, the first sealing member 22 includes an enclosure portion 222, the enclosure portion 222 is extended toward the oil storage member 11, the enclosure portion 222 encloses a liquid storage tank 2221, the bottom of the oil storage member 11 extends into the liquid storage tank 2221 and abuts against the bottom of the liquid storage tank 2221 to enclose and form a gas gathering cavity 40, wherein the air hole 41 is provided on the side wall at the bottom of the oil storage member 11. In other embodiments, the first sealing member 22 and the oil storage member 11 may be connected in a manner other than limited thereto to form the gas gathering cavity 40; for example: the air hole 41 may also be provided on the enclosure portion 222; for another example: a card slot is provided at the bottom of the oil storage member 11, the first sealing member 22 extends into the card slot and together encloses and forms the gas gathering cavity 40.

[0043] In one embodiment, a first limiting ring 2211 and a second limiting ring 2212 are provided on the inner wall of the sensing cavity 221, the sensing microphone 21 is installed between the first limiting ring 2211 and the second limiting ring 2212, the surfaces on opposite sides of the sensing microphone 21 are respectively against the first limiting ring 2211 and the second limiting ring 2212, and the sensing cavity 221 passes through the first sealing member 22.

[0044] Specifically, the sensing cavity 221 runs through the first sealing member 22, and the first sealing member 22 is made of a flexible silicone material. The purpose of such a setting is that the first sealing member 22 will deform when under pressure. When the sensing microphone 21 needs to be installed in the sensing cavity 221, the first sealing member 22 can be pressed to enlarge the cavity opening of the sensing cavity 221 away from the oil storage member 11, so that the sensing microphone 21 can be installed in the sensing cavity 221, and the sensing microphone 21 is abutted between the first limiting ring 2211 and the second limiting ring 2212 to fix the sensing microphone 21. Compared with the glue attachment method, the above method can reduce the steps of applying glue. Moreover, the glue attachment method may cause the glue to block the cavity opening of the sensing cavity 221, resulting in poor sensing effect of the sensing microphone 21.

[0045] It is understandable that, see Appendix Figure 4 , the first limiting ring 2211 and the second limiting ring 2212 are respectively located at the upper and lower sides of the sensing microphone 21, and the circumferential outer side wall of the sensing microphone 21 abuts against the cavity wall of the sensing cavity 221. In other words, after the sensing microphone 21 is placed in the sensing cavity 221, the upper and lower sides of the sensing microphone 21 are respectively limited by the first limiting ring 2211 and the second limiting ring 2212, so that the sensing microphone 21 is difficult to move up and down; the circumferential outer side wall of the sensing microphone 21 abuts against the cavity wall of the sensing cavity 221, so that the sensing microphone 21 is difficult to move circumferentially, that is, the sensing microphone 21 is limited circumferentially. Compared with the method of gluing or welding, the limiting method by clamping can reduce the number of steps.

[0046] In this embodiment, the first limiting ring 2211 and the second limiting ring 2212 are manufactured integrally with the first sealing member 22 ; in other embodiments, the first limiting ring 2211 and the second limiting ring 2212 may be separate components.

[0047] See also Figure 5 and Figure 6 , Figure 5 yes Figure 1 The structural diagram of the first seal, Figure 6 yes Figure 3 Schematic diagram of the cross-sectional structure after the middle oil storage component and the first sealing component are matched.

[0048] In one embodiment, the first sealing member 22 further includes a seat portion 223 and a protrusion 224. The seat portion 223 is snap-fitted to the oil storage member 11. The protrusion 224 is connected to the seat portion 223. The protrusion 224 is protruded from the end surface of the seat portion 223 facing the oil storage member 11. The sensing cavity 221 passes through the protrusion 224.

[0049] Specifically, the atomizer assembly 13 generates a large amount of smoke during the process of heating the e-liquid, and a small amount of condensate will appear during the process of the smoke rising from the air guide channel 12, and the condensate will drip along the air guide channel 12 to the direction of the gas collection chamber 40. In addition, the protrusion 224 is connected to the seat body 223, and the protrusion 224 and the seat body 223 are manufactured as one piece. The protrusion 224 is convexly arranged on the end surface of the seat body 223 facing the oil storage member 11. The purpose of such arrangement is that when the condensate drips on the end surface of the seat body 223, the condensate will not fall into the protrusion 224 along the end surface of the seat body 223. In addition, the induction chamber 221 runs through the protrusion 224, so that the induction microphone 21 in the induction chamber 221 can be protected from being contaminated by the condensate.

[0050] In this embodiment, the enclosure 222 is connected to the base 223, and the enclosure 222 and the protrusion 224 are both located on one side of the base 223. The enclosure 222 is protruded from the end surface of the base 223. The enclosure 222 and the base 223 enclose the liquid storage tank 2221, and the protrusion 224 is located in the liquid storage tank 2221. The purpose of this arrangement is that the condensed liquid will drip into the liquid storage tank 2221 after dripping, so as to achieve the purpose of collecting the condensed liquid.

[0051] In one embodiment, the central axis of the air guide channel 12 and the central axis of the protrusion 224 are staggered.

[0052] It should be noted that the air guide channel 12 and the raised portion 224 are both roughly cylindrical, and the central axis of the air guide channel 12 and the central axis of the raised portion 224 are staggered, that is, the lower end of the air guide channel 12 is staggered with the raised portion 224. This arrangement makes it difficult for condensate dripping from the air guide channel 12 to directly drip into the raised portion 224, thereby protecting the sensing microphone 21 in the sensing cavity 221.

[0053] Re-reference Figure 4 and Figure 6 In one embodiment, the atomization module 10 further includes an air guide tube 131, the air guide channel 12 is opened in the air guide tube 131, the oil storage member 11 includes a base portion 111 and a mounting portion 112, the base portion 111 is snap-fitted with the first sealing member 22, the mounting portion 112 is connected to the base portion 111, the mounting portion 112 is extended from the first sealing member 22 to the oil storage member 11, the mounting portion 112 extends into the air guide channel 12 so that the air guide tube 131 is snap-fitted with the mounting portion 112, the mounting portion 112 is provided with a connecting channel 1121, and the connecting channel 1121 is connected to the air guide channel 12 and the gas gathering chamber 40.

[0054] Specifically, the air guide tube 131 is roughly cylindrical and is contained in the oil storage part 11. During the assembly of the aerosol generating device 100, the air guide tube 131 is placed in the oil storage part 11, and the mounting portion 112 is extended into the air guide tube 131, so that the air guide tube 131 is engaged with the oil storage part 11, to ensure the stability of the air guide tube 131 after installation. The mounting portion 112 is provided with a connecting channel 1121, which connects the air guide channel 12 and the gas collecting chamber 40, so as to ensure that the air guide channel 12 and the gas collecting chamber 40 are connected.

[0055] It should be noted that the mounting portion 112 and the base portion 111 are integrally manufactured, and the central axis of the mounting portion 112 is staggered from the central axis of the raised portion 224. This arrangement allows the air guide tube 131 to be installed without having to consider whether the central axis of the air guide tube 131 and the central axis of the raised portion 224 are in the same straight line, and can ensure that the condensate generated by the air guide channel 12 is difficult to drip directly into the sensing cavity 221.

[0056] In one embodiment, the base portion 111 is provided with a first communication hole 1111, the seat body portion 223 is provided with a second communication hole 2231, and the atomizer assembly 13 includes a pin 132, the pin 132 is inserted into the air guide channel 12, the pin 132 abuts against the side wall of the air guide channel 12, and the pin 132 abuts between the air guide tube 131 and the mounting portion 112;

[0057] See also Figure 7 , Figure 7 It is a structural diagram of the inductive microphone and adapter board.

[0058] The battery module 30 includes an adapter plate 31, which is connected to the first sealing member 22. The adapter plate 31 includes a welding portion 311, and the welding portion 311 is provided with a third connecting hole 3111. The pin 132 is sequentially inserted into the first connecting hole 1111, the second connecting hole 2231 and the third connecting hole 3111.

[0059] The sensing microphone 21 also includes a microphone line 211, which is electrically connected to the sensing microphone 21. The microphone line 211 includes a connecting line segment 2111 and a welding line segment 2112. The connecting line segment 2111 is electrically connected between the welding line segment 2112 and the sensing microphone 21. The welding line segment 2112 is placed flat on a side of the welding portion 311 away from the second connecting hole 2231, and the portion of the pin 132 passing through the third connecting hole 3111 is welded to the welding line segment 2112.

[0060] Specifically, the adapter plate 31 is roughly in the shape of a circular plate, and the welding portion 311 is a part of the adapter plate 31. For ease of understanding, the adapter plate 31 can be made of high-temperature resistant glass fiber material, and the welding portion 311 can be made of copper foil material, so that during the welding process, the welding portion 311 can be welded, and the adapter plate 31 can play a supporting role.

[0061] The microphone line 211 includes a connecting line segment 2111 and a welding line segment 2112, wherein the connecting line segment 2111 and the welding line segment 2112 are integrally manufactured, and the welding line segment 2112 is placed flat on the side of the welding portion 311 away from the second connecting hole 2231. In this embodiment, the welding line segment 2112 can be bent relative to the connecting line segment 2111 so that the length direction of the welding line segment 2112 is consistent with the length direction of the welding portion 311, and the connecting line segment 2111 is vertically arranged relative to the welding line segment 2112 so that the welding line segment 2112 and the welding portion 311 are abutted. The purpose of such arrangement is that before the welding line segment 2112 and the welding portion 311 are not welded, the welding line segment 2112 can be effectively supported by the connecting line segment 2111, thereby facilitating the subsequent welding of the welding line segment 2112 and the pin 132; this welding method has a fixed welding position and will not cause puncture, and such arrangement is also convenient for realizing automatic welding.

[0062] In addition, the pin 132 includes a first pin segment 1321, a second pin segment 1322 and a third pin segment 1323, which are connected in sequence and are integrally manufactured. The first pin segment 1321 abuts against the side wall of the air guide channel 12, and the second pin segment 1322 is clamped between the air guide tube 131 and the mounting portion 112. In other words, when the air guide tube 131 is clamped with the mounting portion 112, the air guide tube 131 abuts against the pin 132 and clamps toward the mounting portion 112, so that the second pin segment 1322 is clamped between the air guide tube 131 and the mounting portion 112 to ensure the stable installation of the pin 132. The third pin segment 1323 is sequentially penetrated through the first connecting hole 1111, the second connecting hole 2231 and the third connecting hole 3111. The above method can ensure that the second pin segment 1322 and the first pin segment 1321 are fixed before the third pin segment 1323 is welded, so as to ensure the stability of the third pin segment 1323 during the welding process.

[0063] Optionally, the third pin segment 1323 and the oil storage member 11 are sealed by gluing to prevent the tobacco oil in the oil storage member 11 from penetrating the first connecting hole 1111 and the second connecting hole 2231 to contaminate the battery module 30 .

[0065] In this embodiment, the atomizer assembly 13 further includes an oil guide member 133, a heating member 134 and a sleeve member 135. An installation port 1311 is provided on the air guide tube 131. Two installation ports 1311 are provided. The two installation ports 1311 are arranged opposite to each other. The opposite sides of the oil guide member 133 pass through the two installation ports 1311, and the oil guide member 133 is partially located in the oil storage member 11, so that the smoke oil in the oil storage member 11 can penetrate into the oil guide member 133. In this embodiment, the oil guide member 133 is made of a glass fiber tube, the heating member 134 is threadedly sleeved on the oil guide member 133, and the heating member 134 is located in the air guide channel 12. The heating member 134 is made of metal material, and the heating member 134 is electrically connected to the battery module 30 through the pin 132.

[0066] Furthermore, in order to facilitate the installation of the oil guide member 133 on the air guide tube 131, a cutout 1312 is provided on the air guide tube 131, and the cutout 1312 is connected to the installation opening 1311. The air guide tube 131 can be bent along the cutout 1312, and the oil guide member 133 is placed therein, and the opposite sides of the oil guide member 133 are respectively inserted into one installation opening 1311. Then, the sleeve member 135 is sleeved outside the air guide tube 131 to prevent the air guide tube 131 from bending.

[0067] See also Fig. 9 and Fig.10 , Fig. 9 yes Figure 1 Schematic diagram of the matching structure of the middle oil storage component and the second sealing component; Fig.10 yes Figure 1 Schematic diagram of the structure of the second seal.

[0068] In one embodiment, the aerosol generating device 100 also includes a second seal 50, which is sealingly connected to the end of the oil storage member 11 facing away from the first seal 22. The second seal 50 includes a positioning groove 51, and the air guide tube 131 extends into the positioning groove 51 and is clamped with the second seal 50. The second seal 50 is provided with a ventilation channel 52, and the ventilation channel 52 is connected to the air guide channel 12.

[0069] Specifically, the second seal 50 is made of silicone material. The second seal 50 is sealed and connected to the end of the oil storage member 11 away from the first seal 22, so that the second seal 50 and the oil storage member 11 are enclosed to form an oil storage bin, so as to achieve the sealing effect of the oil storage bin. The second seal 50 includes a sealing portion 53 and a positioning portion 54. The positioning portion 54 is connected to the sealing portion 53. The sealing portion 53 is sealed and connected to the end of the oil storage member 11. The positioning portion 54 extends into the air guide tube 131. The positioning groove 51 is located on the sealing portion 53, and the notch of the positioning groove 51 faces the first seal 22. When installing the air guide tube 131, the positioning groove 51 is aligned with the air guide tube 131, and the positioning portion 54 is extended into the air guide channel 12, so that the ventilation channel 52 and the air guide channel 12 are connected. It is understandable that during the installation of the air guide tube 131 , the opposite ends of the air guide tube 131 are respectively engaged with the oil storage member 11 and the second sealing member 50 , so that the installation of the air guide tube 131 is more stable.

[0070] In one embodiment, the second seal 50 includes a locking portion 55 and a locking portion 56. The locking portion 55 is inclined toward the end face of the first seal 22. The ventilation channel 52 runs through the locking portion 55. The locking portion 56 is sleeved outside the locking portion 55. The cross-sectional area of ​​the locking portion 56 gradually increases along the direction from the first seal 22 to the second seal 50, and the locking portion 56 abuts against the side wall of the air guide channel 12.

[0071] Specifically, the locking portion 55 is connected to the sealing portion 53, and the locking portion 55 is inclined toward the end surface of the first sealing member 22, that is, the end of the locking portion 55 is roughly triangular, so that the second sealing member 50 can be inserted into the air guide channel 12. The locking portion 56 is sleeved outside the locking portion 55, and the cross-sectional area of ​​the locking portion 56 gradually increases from the first sealing member 22 to the second sealing member 50, so that the locking portion 55 can be locked in the air guide channel 12. It can be understood that the locking portion 55 facilitates the second sealing member 50 to extend into the air guide channel 12, and the locking portion 56 facilitates the second sealing member 50 to be locked in the air guide channel 12.

[0072] Moreover, the sealing portion 53 , the positioning portion 54 , the locking portion 55 and the locking portion 56 are manufactured in one piece, and in this embodiment, the second sealing member 50 is made of silicone material.

[0073] See also Fig.11 , Fig.11 yes Figure 1Schematic diagram of the cross-sectional structure after the middle oil storage part and the second sealing part cooperate. In one embodiment, the aerosol generating device 100 further includes a housing 60, which is sleeved outside the oil storage part 11, and the housing 60 is provided with an air inlet 61, and the air inlet 61 is respectively connected with the air hole 41 and the outside; a notch 225 is provided on the outer wall of the first sealing part 22, and the notch 225 corresponds to the position of the air inlet 61 and is connected, and the air hole 41 is located between the notch 225 and the air guide tube 131, and the air hole 41 is connected with the notch 225.

[0074] The atomization module 10, the induction component 20 and the battery module 30 are all arranged inside the housing 60. Specifically, when the user uses the aerosol generating device 100 to inhale, the external gas enters through the air inlet 61 and enters the gas collection chamber 40 along the path of the notch 225 and the air hole 41. Among them, the positions of the air inlet 61 and the notch 225 correspond to each other, and the air hole 41 is located between the notch 225 and the air guide tube 131, and the air hole 41 is connected to the notch 225. The purpose of this arrangement is that the external gas enters through the air inlet 61 and flows along the notch 225 to the air hole 41. For example: Figure 4 In the drawings shown, the gas will flow upward after entering from the notch 225 until the gas flows to the air hole 41, so that when the air is inhaled, the positive impact force of the airflow on the side wall of the notch 225 is reduced, thereby reducing the noise generated during the intake. Moreover, in this embodiment, the notch 225 is roughly in the shape of an inverted triangle, which further reduces the intake noise.

[0075] Here, it needs to be further explained that the aerosol generating device 100 also includes a nozzle, which cooperates with the shell 60 to form an external shell of the aerosol generating device 100; wherein the nozzle can be used for inhalation by the user, and the specific structure of the nozzle can be replaced according to actual needs, which will not be elaborated here.

[0076] Optionally, the first sealing member 22 is connected to the lower end of the oil storage member 11 and is sealed to the inner side wall of the housing 60, and the air inlet 61 is opened on the side wall of the housing 60 and is located above the first sealing member 22. When the user inhales through the mouthpiece, the external air passes through the air inlet 61, the air hole 41 and the air collection cavity in sequence, enters the air guide channel 12 and mixes with the smoke, and then flows upward into the mouthpiece and is inhaled by the user.

[0077] Compared with the bottom air intake solution in the prior art, the air flow channel in this embodiment is relatively independent and more stable, and the suction effect will not be affected when the housing 60 and the first seal 22 leak. In other words, the bottom air intake solution in the prior art will not produce smoke when there is an assembly gap between the housing and the seal inside it, which affects the suction effect.

[0078] In one embodiment, an annular channel 1112 is opened on the outer wall of the base portion 111, and the annular channel 1112 is respectively connected to the air inlet hole 61 and the air through hole 41. The gas enters the gas gathering chamber 40 through the air inlet hole 61, the annular channel 1112 and the air through hole 41 in sequence, and the air inlet hole 61 and the air through hole 41 are staggered.

[0079] Specifically, the annular channel 1112 is located between the notch 225 and the oil storage member 11, and the air hole 41 is provided on the side wall of the annular channel 1112. If the annular channel 1112 is provided on the first sealing member 22, when the first sealing member 22 is engaged with the oil storage member 11, deformation is likely to occur, resulting in deformation of the annular channel 1112. In other words, if the annular channel 1112 and the air hole 41 are provided on the first sealing member 22, they are likely to be blocked, resulting in poor air intake effect.
