Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an aerosol generating device. Background Art

[0002] Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium. Aerosol can be absorbed by the human body through the respiratory system and provide users with a new alternative absorption method.

[0003] For example, an aerosol generating device that can bake and heat aerosol-generating matrices such as herbs, ointments, and liquids to produce aerosols can be used in different fields to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0004] Traditional aerosol generators adjust the airflow by rotating a component that controls the airflow, adjusting the airflow into and out of the device. However, because this component lacks a child-proof lock, it can easily be accidentally activated or inhaled by children, posing a significant safety hazard. Summary of the Invention

[0012] In one embodiment, the locking portions at different positions are spaced apart along the axial direction of the limiting channel; when the air regulating member slides relative to the housing along the axial direction of the limiting channel, the assembly portion is aligned with the locking portions at different positions in sequence.

[0013] In one embodiment, the locking portions at different positions are arranged at intervals along the circumference of the limiting channel; when the air regulating component rotates around its own axis relative to the housing, the assembly portion is aligned with the locking portions at different positions in sequence.

[0014] In one embodiment, the limiting channel has a first section (152) located inside the accommodating cavity and a second section located outside the accommodating cavity and connected to the first section, the channel wall structure of the first section is formed with the air inlet, and the locking parts at different positions are arranged at intervals along the circumference of the second section.

[0015] In one embodiment, the housing includes a housing body and a first annular limiting platform provided on the housing body, wherein the first limiting platform is located in the accommodating cavity and defines the first section;

[0016] The aerosol generating device further includes a sealing member, which is arranged in the first section and sealed between the gas regulating member and the first limiting platform.

[0017] In one embodiment, the housing includes a housing body and a second annular limiting platform provided on the housing body, the second limiting platform is located outside the accommodating cavity and defines the second section, and each of the locking portions is formed by a limiting recess provided along the radial direction of the second limiting platform.

[0018] The gas regulating member further includes a main body portion at least partially disposed in the second section, and the assembly portion is coupled to the main body portion and protrudes radially from the main body portion.

[0019] When the assembly part is inserted into any of the locking parts, the assembly part is locked with the locking part; when the assembly part is withdrawn from the locking part, the assembly part is unlocked from the locking part.

[0020] In one embodiment, the assembly portion is an elastic portion, and the assembly portion is withdrawn from the locking portion under the action of an external force and stores elastic potential energy;

[0021] When the air regulating member rotates until the assembling portion is aligned with the target locking portion, the assembling portion releases elastic potential energy and automatically inserts into the target locking portion.

[0022] In one embodiment, the gas regulating member further includes a main body and an elastic connecting portion, and the elastic connecting portion is assembled on the main body;

[0023] There are at least two assembling parts, and at least part of all the assembling parts are arranged at two opposite ends of the elastic connecting part.

[0024] In one embodiment, the main body has a bearing surface facing the accommodating cavity, the bearing surface includes a first sub-surface and a second sub-surface, there is a height difference between the first sub-surface and the second sub-surface, and the first sub-surface is closer to the accommodating cavity than the second sub-surface;

[0025] The elastic connecting portion and all the assembly portions are supported on the second sub-surface.

[0026] In one embodiment, the bearing surface further includes a connecting sub-surface connected between the first sub-surface and the second sub-surface, and each of the assembly portions provided at opposite ends of the elastic connecting portion rests on the connecting sub-surface.

[0030] When the air inlet is opened, the sensing air channel is connected to the air inlet; when the air inlet is closed, the sensing air channel is isolated from the air inlet.

[0031] In one embodiment, the locking portion that is locked with the assembly portion when the air inlet is closed is defined as a first locking portion;

[0032] When the assembling portion is locked with the first locking portion, the air regulating component closes the sensing air passage.

[0033] To activate the aerosol generating device, the assembly and locking parts must first be unlocked before the air-regulating element can be rotated relative to the housing to open the air inlet. In the present application, since the assembly and locking parts must be unlocked before the air-regulating element can be rotated, this arrangement increases the difficulty of adjusting the air-regulating element. This prevents children from accidentally activating or inhaling the aerosol, thereby adjusting the airflow while reducing safety risks associated with the aerosol generating device.

[0053] Please also refer to Figure 1 and Figure 2 The present application provides an aerosol generating device 1, which includes a housing 10, an air regulating component 20, a power supply component 30, and an atomizing assembly 40. The housing 10 is used to provide a mounting base for the air regulating component 20, the power supply component 30, and the atomizing assembly 40. The air regulating component 20 is used to adjust the air intake of the aerosol generating device 1, and the power supply component 30 is used to supply power to the atomizing assembly 40. The atomizing assembly 40 is used to atomize an aerosol-generating substrate therein to form an aerosol when powered.

[0054] Please also refer to Figure 3 、 Figure 4 and Figure 5, wherein the housing 10 has an accommodating cavity and an air inlet 151 and an air outlet 121 both of which are in communication with the accommodating cavity, and at least two locking portions 132 at different positions are formed on the housing 10. The power supply 30 and the atomizing assembly 40 are both arranged in the accommodating cavity, and the air regulating component 20 is matched with the housing 10, and an assembly portion 22 is also formed thereon. The air regulating component 20 is constructed to be able to move relative to the housing 10 so that the assembly portion 22 is locked or unlocked with the locking portions 132 at different positions, and when the assembly portion 22 is locked with the locking portions 132 at different positions, the air inlet 151 has different openings.

[0055] Optionally, the main body that controls the unlocking of the assembly portion 22 from the locking portion 132 at a different position and controls the movement of the air-regulating member 20 relative to the housing 10 can be a driving member. Preferably, the main body that controls the unlocking of the assembly portion 22 from the locking portion 132 at a different position and controls the movement of the air-regulating member 20 relative to the housing 10 is a user. This not only reduces the cost of the aerosol generating device 1, but also reduces the size of the aerosol generating device 1, thereby facilitating the miniaturization of the aerosol generating device 1. The following embodiments are all described using the example of a user controlling the movement of the air-regulating member 20.

[0056] The differently positioned locking portions 132 are different locking portions 132 that, when locked with the assembly portion 22, ensure that the air inlet 151 has different openings. Furthermore, when the differently positioned locking portions 132 are locked with the assembly portion 22, the relative positions of the air regulating element 20 and the housing 10 also differ. The number of differently positioned locking portions 132 can be two, three, or even more.

[0057] Taking the case 10 having two locking portions 132 in different positions as an example, when the assembly portion 22 is locked with one of the locking portions 132, the air inlet 151 is closed, and when the assembly portion 22 is locked with the other locking portion 132, the air inlet 151 is open. The opening degree of the air inlet 151 is defined as K. A closed air inlet 151 means that the opening degree K of the air inlet 151 is 0, and external air cannot enter the accommodating cavity through the air inlet 151. An open air inlet 151 means that the air inlet 151 is at least partially open, and its opening degree K may be 60%, 80%, or 100%, and can be set according to the user's needs.

[0058] Taking the case 10 as an example, the locking portion 132 formed with at least three different positions is defined as the first locking portion when the air inlet 151 is closed and the locking portion 132 locked with the assembly portion 22 when the air inlet 151 is open. The locking portion 132 with different positions includes a first locking portion and at least two second locking portions with different positions, and when the second locking portions with different positions are locked with the assembly portion 22, the air inlet 151 has different openings. For example, when the assembly portion 22 is locked with one of the second locking portions, the opening K of the air inlet 151 is 60%, and when the assembly portion 22 is matched with the other second locking portion, the opening K of the air inlet 151 is 100%. After the aerosol generating device 1 is started, the user can adjust the locking of the assembly portion 22 with the second locking portions with different positions according to their own needs.

[0059] During actual operation, before starting, the assembly part 22 is always locked with the first locking part. At this time, the air inlet 151 is closed and the aerosol generating device 1 cannot perform the atomization operation. When the user needs to use the aerosol generating device 1 for atomization, the user controls the assembly part 22 to unlock the first locking part. Then, the user operates the air regulating part 20 relative to the housing 10 until the assembly part 22 is aligned with the target second locking part. Then, the assembly part 22 is controlled or automatically locked with the target second locking part. At this time, the air inlet 151 is opened, and the external air flow can flow into the accommodating cavity through the air inlet 151, and after mixing with the aerosol formed by atomization, it is output from the air outlet 121 and inhaled by the user. After the atomization is completed, the user operates the assembly part 22 to unlock the target second locking part, and then controls the air regulating part 20 to move in the opposite direction until the assembly part 22 can be re-aligned with the first locking part and locked. At this time, the air inlet 151 is closed again to prevent the outside from continuing to take in air.

[0060] The target second locking portion refers to the second locking portion that engages with the assembly portion 22 when the air inlet 151 reaches a desired opening. For example, if the user desires an opening K of 60% for the air inlet 151, the locking portion 132 that engages with the assembly portion 22 when the air inlet 151 is opened at 60% is the target second locking portion.

[0061] In the present application, since the aerosol generating device 1 in the air regulating part 20 needs to control the assembly part 22 to be unlocked from the locking part 132 currently locked with the assembly part 22 before the air regulating part 20 can be operated to rotate, this setting method increases the difficulty of adjusting the air regulating part 20, so it can prevent children from accidentally starting or inhaling, thereby reducing the safety hazards of the aerosol generating device 1.

[0062] It's worth noting that, in this application, to prevent the air inlet 151 from being blocked when the user operates the aerosol generating device 1, the air inlet 151 and the air outlet 121 are spaced apart at opposite ends of the housing 10. During normal use, the user typically holds the housing 10 in the middle between the two ends and inhales the aerosol through the air outlet 121. By designing the air inlet 151 and the air outlet 121 spaced apart at opposite ends of the housing 10, the aerosol generating device 1 is ensured to have free air intake.

[0063] Please also refer to Figure 6 In one embodiment, the housing 10 is provided with a limiting passage 17, the wall of which is formed with an air inlet 151 and locking portions 132 at different locations. The air regulating member 20 is disposed and constrained within the limiting passage 17. The air regulating member 20 includes an air inlet passage 25, which has an air outlet 253. When the assembly portion 22 is locked with the locking portions 132 at different locations, the air outlet 253 and the air inlet 151 have different overlapping areas.

[0064] Specifically, the air regulating member 20 includes a main body 21 and an air regulating portion 23 . The air regulating portion 23 and the assembly portion 22 are both connected to the main body 21 , and the air inlet passage 25 passes through the main body 21 and the air regulating portion 23 .

[0065] The overlapping area between the exhaust port 253 and the air inlet 151 refers to the area defined by the wall edge of the exhaust port 253 and the area defined by the edge of the air inlet 151, along the extension direction of the central axis of the air inlet 151. The larger the overlapping area, the wider the opening of the air inlet 151.

[0066] Optionally, there can be only one air inlet 151, and if the overlapping area of the exhaust port 253 with the air inlet 151 is different, the opening of the air inlet 151 will also be different. Alternatively, the air inlet 151 may also include a plurality of sub-air inlets, and the plurality of sub-air inlets may have the same or different calibers. Taking the example of the plurality of sub-air inlets having the same caliber, by controlling the exhaust port 253 to overlap with different numbers of sub-air inlets, the air inlet 151 can have different openings. Taking the example of the plurality of sub-air inlets having different calibers, by controlling the exhaust port 253 to overlap with sub-air inlets of different calibers, the air inlet 151 can have different openings.

[0067] By providing the limiting channel 17 , the limiting channel 17 has a limiting and guiding effect on the air regulating member 20 , so that the air regulating member 20 can stably move relative to the housing 10 , thereby helping to improve the accuracy of adjusting the opening of the air inlet 151 .

[0068] In one embodiment, all the locking portions 132 at different positions are spaced apart along the axial direction of the limiting passage 17. When the air regulating member 20 slides relative to the housing 10 along the axial direction of the limiting passage 17, the assembly portion 22 is sequentially aligned with the locking portions 132 at different positions. With this design, the air regulating member 20 is easy to operate and highly efficient.

[0069] In another embodiment, locking portions 132 at different locations are spaced apart along the circumference of the limiting channel 17. As the air-regulating element 20 rotates about its axis relative to the housing 10, the assembly portion 22 aligns with the locking portions 132 at different locations. As the air-regulating element 20 rotates about its axis, the space it occupies remains fixed, thereby reducing the space required for its installation and contributing to the miniaturization of the aerosol generating device 1.

[0070] In one embodiment, the limiting channel 17 has a first section 152 located inside the accommodating cavity and a second section 141 located outside the accommodating cavity and connected to the first section 152. The channel wall structure of the first section 152 is formed with an air inlet 151, and the locking portions 132 at different positions are arranged at intervals along the circumference of the second section 141.

[0071] Specifically, the air regulating portion 23 is limited to the first section 152, and the main body 21 and the assembly portion 22 are both limited to the second section 141. In this way, the user can operate the main body 21 from the outside to drive the assembly portion 22 and the air regulating portion 23 to rotate to adjust the opening of the air inlet 151.

[0072] Please refer again Figure 3 , and see also Figure 8 In one embodiment, the housing 10 includes a housing body and an annular first stop 15 disposed on the housing body. The first stop 15 is located within the accommodating cavity and defines a first section 152. The aerosol generating device 1 also includes a sealing member 50 disposed within the first section 152 and sealing between the gas regulating member 20 and the first stop 15.

[0073] Among them, the sealing member 50 is annular and is arranged outside the air regulating part 23. The setting of the sealing member 50 can seal between the air regulating part 23 and the first limit platform 15 to prevent the external air flow from flowing into the accommodating cavity through the limit channel 17 and the air inlet 151, thereby ensuring the reliability of the external air flow input through the air inlet channel 25 and the air inlet 151.

[0074] Please refer again Figure 5 and Figure 6In one embodiment, the housing 10 includes a housing body and a second annular limiting platform 14 provided on the housing body. The second limiting platform 14 is located outside the accommodating cavity and defines a second section 141. Each locking portion 132 is formed by a limiting recessed portion provided along the radial direction of the second limiting platform 14. The air regulating member 20 also includes a main body 21 at least partially provided within the second section 141. The assembly portion 22 is coupled to the main body 21 and protrudes radially from the main body 21. When the assembly portion 22 is inserted into any locking portion 132, the assembly portion 22 is locked with the locking portion 132. When the assembly portion 22 is withdrawn from the locking portion 132, the assembly portion 22 is unlocked from the locking portion 132.

[0075] That is, the assembly portion 22 is a convex portion, and each locking portion 132 is a concave portion. The assembly portion 22 is inserted into the locking portion 132 to achieve locking, and the assembly portion 22 is removed from the locking portion 132 to achieve unlocking. The operation mode is simple and efficient, allowing the aerosol generating device 1 to be quickly started or closed.

[0076] Furthermore, the assembly portion 22 is an elastic portion, and when an external force is applied to the assembly portion 22 to withdraw from the locking portion 132 and store elastic potential energy. When the gas regulating member 20 rotates until the assembly portion 22 is aligned with the target locking portion 132, the assembly portion 22 releases the elastic potential energy and automatically inserts into the target locking portion 132.

[0077] The target locking portion 132 refers to the locking portion 132 that cooperates with the assembly portion 22 when the air inlet 151 reaches an opening that satisfies the user. It may be the first locking portion or any of the second locking portions mentioned above.

[0078] In actual operation, when the user wishes to adjust the opening of the air inlet 151, they squeeze the locking portion 132 currently engaged with the assembly portion 22, causing the assembly portion 22 to unlock from the currently engaged locking portion 132. During this process, the assembly portion 22 deforms and stores elastic potential energy. Subsequently, the user drives the air regulating member 20 to rotate relative to the housing 10 until it aligns with the desired locking portion 132. The user then releases the external force, at which point the assembly portion 22 releases its elastic potential energy and automatically inserts into the desired locking portion 132.

[0079] Because the assembly portion 22 is elastic, its deformation during unlocking increases the difficulty of unlocking, further preventing accidental activation and inhalation by children. Furthermore, the assembly portion 22 and the target locking portion 132 can be automatically locked without external manipulation, thus enhancing the ease of locking.

[0080] Furthermore, the main body 21 is provided with a relief opening 211 corresponding to the assembly portion 22. During the squeezing process, the assembly portion 22 can partially extend into the relief opening 211. This allows the assembly portion 22 to exit the locking portion 132 with minimal deformation. Thus, the provision of the relief opening 211 can reduce the external force applied by the user to the assembly portion 22, thus making operation more labor-saving.

[0081] Furthermore, the assembly portion 22 extends away from the housing body and out of the second section 141. Thus, the user can squeeze the portion of the assembly portion 22 extending out of the second section 141 to drive the assembly portion 22 out of the locking portion 132. This operation method is simple and easy, and has high operational efficiency.

[0082] Please also refer to Figure 7 In one embodiment, the air regulating member 20 further includes an elastic connecting portion 24, which is assembled to the main body 21; and at least two assembly portions 22, with at least some of the assembly portions 22 being disposed at opposite ends of the elastic connecting portion 24. Preferably, there are two assembly portions 22, each disposed at opposite ends of the elastic connecting portion 24.

[0083] When the air regulating member 20 rotates to each position where it mates with the housing 10 and adjusts the opening of the air inlet 151, the multiple locking portions 132 in the same position can mate with all the assembly portions 22. Furthermore, it is worth mentioning that the main body 21 also has multiple avoidance openings 211, and all of the avoidance openings 211 also correspond one-to-one with the two assembly portions 22.

[0084] The locking portions 132 in the same position are all locking portions 132 that, when locked one-to-one with all the assembly portions 22, ensure that the air inlet 151 has the same opening. When all the locking portions 132 in the same position are locked one-to-one with all the assembly portions 22, the relative position of the air regulating element 20 and the housing 10 remains unchanged, and the opening of the air inlet 151 also remains unchanged.

[0085] To adjust the opening of the air inlet 151, pinch the portions of the assembly portions 22 at opposite ends of the elastic connection 24 that extend beyond the second section 141, forcing each assembly portion 22 to withdraw from its corresponding, identically positioned locking portion 132. Then, continue pinching the portions of the assembly portions 22 at opposite ends of the elastic connection 24 that extend beyond the second section 141 and rotate the air modulator 20 relative to the housing 10, aligning the two assembly portions 22 with the two identically positioned target locking portions 132. The external force is then released, and the two assembly portions 22 are inserted into their respective target locking portions 132, completing the adjustment of the air inlet 151 opening.

[0086] In some embodiments, all mounting portions 22 may be provided only at opposite ends of the elastic connection portion 24, or all mounting portions 22 may be provided at intervals along the circumference of the elastic connection portion 24. It is sufficient to ensure that mounting portions 22 are provided at opposite ends of the elastic connection portion 24. The following embodiments are described using an example in which two mounting portions 22 are provided, one at each of the opposite ends of the elastic connection portion 24.

[0087] In one embodiment, the main body 21 has a supporting surface 212 facing the accommodating cavity. The supporting surface 212 includes a first sub-surface 2121 and a second sub-surface 2122. There is a height difference between the first sub-surface 2121 and the second sub-surface 2122, and the first sub-surface 2121 is closer to the accommodating cavity than the second sub-surface 2122. The elastic connecting portion 24 and all the assembly portions 22 are supported on the second sub-surface 2122.

[0088] That is, there is a height difference between the first sub-surface 2121 and the second sub-surface 2122, and the elastic connection portion 24 and all the assembly portions 22 are supported on the second sub-surface 2122, which is lower than the first sub-surface 2121. This design facilitates the assembly of the elastic connection portion 24 and all the assembly portions 22 and reduces the occupied volume of the gas regulating member 20.

[0089] Furthermore, the bearing surface 212 further includes a connecting sub-surface 2123 connected between the first sub-surface 2121 and the second sub-surface 2122. Each assembly portion 22 provided at opposite ends of the elastic connecting portion 24 rests on the connecting sub-surface 2123. In other words, the first sub-surface 2121, the connecting sub-surface 2123, and the second sub-surface 2122 are connected to form a stepped surface.

[0090] The assembly parts 22 provided at the opposite ends of the elastic connecting part 24 are supported by the connecting sub-surface 2123. In this way, when the assembly parts 22 at both ends are pinched toward each other and the entire air regulating part 20 is operated to rotate, the connecting sub-surface 2123 can provide force supporting points for the assembly parts 22 at both ends to prevent the elastic connecting part 24 and the assembly part 22 from sliding relative to the main body 21, thereby making the rotation of the air regulating part 20 smoother.

[0091] Furthermore, each assembly portion 22 includes a first sub-portion 221 and a second sub-portion 222 that are interconnected. The first sub-portion 221 overlaps the second sub-surface 2122 and is connected to the elastic connecting portion 24. The first sub-portion 221 rests on the connecting sub-surface 2123, and the second sub-portion 222 extends away from the shell body to the outside of the second section 141. For example, each assembly portion 22 can be 7-shaped or T-shaped.

[0092] When the assembly portions 22 at both ends of the elastic connection portion 24 are pinched toward each other and the entire air regulating member 20 is rotated, since the first sub-portions 221 of the two assembly portions 22 are both overlapped on the second sub-surface 2122, the two second sub-portions 222 of the two assembly portions 22 can be squeezed against each other and withdrawn from the corresponding locking portions 132. Moreover, after the two second sub-portions 222 withdraw from the corresponding locking portions 132, the two first sub-portions 221 can still bear on the connecting sub-surface 2123 and provide a force point for rotation.

[0093] In other embodiments, a limiting groove is provided on the bearing surface 212, and the elastic connecting portion 24 extends along the length of the limiting groove and is clamped between two opposing groove walls of the limiting groove, with all the assembly portions 22 disposed outside the limiting groove. The provision of the limiting groove also prevents the elastic connecting portion 24 and the assembly portion 22 from sliding relative to the main body 21, thereby helping to improve the smoothness of rotation of the gas regulating member 20.

[0094] Please refer again Figure 4 , and please also refer to Figure 9 and Figure 11 In one embodiment, the aerosol generating device 1 further includes a microphone 60 . An induction air passage is provided on the housing 10 , and the microphone 60 is disposed in the induction air passage.

[0095] When the air inlet 151 is open, the sensing airway is connected to the air inlet 151. In other words, when the air inlet 151 is open, the interior of the sensing airway is also open, and the sensing airway is in fluid communication with the air inlet 151. Therefore, when the user inhales, the airflow at the microphone 60 can be discharged to the outside through the sensing airway, the air inlet 151, the accommodating cavity, and the air outlet 121, thereby forming a negative pressure at the microphone 60 and achieving activation.

[0096] When the air inlet 151 is closed, the sensing airway is isolated from the air inlet 151. In other words, when the air inlet 151 is closed, the interior of the sensing airway itself acts as a barrier. When the sensing airway is isolated, even if the air inlet 151 is opened, airflow within the sensing airway cannot pass through the air inlet 151 and enter the accommodating chamber. Because the sensing airway is isolated from the air inlet 151 when the air inlet 151 is closed, even if the air inlet 151 is accidentally opened and remains slightly open, the microphone 60 cannot be activated when the user inhales through the air inlet 151, further preventing children from accidentally activating or inhaling the air.

[0097] In one embodiment, the locking portion 132 that engages with the assembly portion 22 when the air inlet 151 is closed is defined as a first locking portion. When the assembly portion 22 is locked with the first locking portion, the air regulating member 20 closes the sensing air passage. When the assembly portion 22 is locked with the second locking portion, the air regulating member 20 opens the sensing air passage.

[0098] There are many ways to open and close the induction air passageway of the air regulating member 20. For example, the air regulating member 20 may include an opening and closing portion that is coupled to the main body 21 and rotates with the main body 21. When the mounting portion 22 is locked with the first locking portion, the opening and closing portion closes the induction air passageway opening for air intake. When the mounting portion 22 is locked with the second locking portion, the opening and closing portion opens the induction air passageway opening for air intake.

[0099] Specifically, the opening and closing portion can be a component provided on the gas regulating member 20 separately from the assembly portion 22. Alternatively, the opening and closing portion can also be formed by the assembly portion 22 extending along the radial direction of the main body 21.

[0100] Please refer again Figure 8 、 Figure 9 and Figure 11 , and also see Figure 10 In one embodiment, the housing 10 includes a microphone cover 16 having a cavity 161 and a first opening 162 and a second opening 163, both communicating with the cavity 161. The microphone 60 is disposed within the cavity 161. The inner wall of the housing body is recessed to form a retaining groove 131. A sensing hole 133 is defined at the bottom of the retaining groove 131. The microphone cover 16 is disposed within the retaining groove 131. The sensing hole 133, the first opening 162, the cavity 161, and the second opening 163 are sequentially connected to form a sensing airway. The sensing hole 133 is spaced away from the first opening 162, forming an air intake opening for the sensing airway, while the second opening 163 forms an air exhaust opening for the sensing airway. The microphone cover 16 protects and positions the microphone 60, ensuring stable installation and a long service life.

[0101] Furthermore, the air inlet channel 25 on the air regulating member 20 includes an air inlet section 251 extending axially along the limiting channel 17 and an air outlet section 252 extending radially along the limiting channel 17. The opening of the air outlet section 252 forms an exhaust port 253. The air regulating portion 23 is also provided with a connecting air channel 231 arranged in a straight line with and connected to the air outlet section 252. The connecting air channel 231 is located outside the air flow path of the air inlet channel 25. A socket 153 is provided radially through the first limiting platform 15. One end of the microphone cover 16 having a second opening 163 is inserted into the socket 153 and abuts against the air regulating portion 23.

[0102] When the air regulating component 20 rotates to the assembly part 22 and cooperates with the first locking part, the area of the overlapping area between the exhaust port 253 of the air outlet section 252 and the air inlet 151 is 0. At the same time, the opening of the connecting air duct 231 and the second opening 163 do not overlap at all. In this way, the air inlet 151 and the sensing air duct are both blocked by the air regulating component 20, and the air inlet 151 and the sensing air duct are closed. When the air regulating member 20 is rotated to the assembly portion 22 to cooperate with the second locking portion, the area of the overlapping region between the exhaust port 253 of the air outlet section 252 and the air inlet 151 is greater than 0. At the same time, the opening of the connecting air duct 231 overlaps with the second opening 163. In this way, the air inlet 151 and the sensing air duct are both opened, and the external air flow can flow into the accommodating cavity through the air inlet channel 25 and the air inlet 151. At the same time, the air flow at the microphone 60 can also flow into the accommodating cavity through the sensing air duct, the connecting air duct 231, the air outlet section 252 of the air inlet channel 25 and the air inlet 151, so that the aerosol generating device 1 can work normally.

[0103] It can be seen that in this embodiment, by operating the air regulating member 20 to rotate, the openings of the air inlet 151 and the sensing air channel can be controlled synchronously, thereby making the operation of the aerosol generating device 1 simpler.

[0104] In one embodiment, the housing body includes a shell 11, a base 13, and a nozzle 12. The shell 11 is a hollow structure with two open ends. The base 13 and nozzle 12 are respectively connected to opposite ends of the shell 11 and define a receiving cavity with the shell 11. The second stop 14 is provided on the outer surface of the base 13, the first stop 15 is provided on the inner surface of the base 13, and the microphone cover 16 is disposed in the stop slot 131 of the base 13.

[0105] When the aerosol generating device 1 is activated, the assembly portion 22 and the locking portion 133 must first be unlocked, and then the air regulating member 20 must be moved relative to the housing 10 until the assembly portion 22 is locked with the corresponding locking portion 132 and the air inlet 151 is opened, thereby enabling atomization and energy supply of the aerosol generating device 1. In the present application, since the assembly portion 22 and all locking portions 132 must be unlocked before the air regulating member 20 can be rotated, this arrangement increases the difficulty of adjusting the air regulating member 20, thereby preventing children from accidentally activating or inhaling the aerosol, thereby reducing the safety risks of the aerosol generating device 1.

[0106] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
