[0066] Please refer to Figures 1 to 7, this application provides an aerosol generating device 1, which includes a housing 20, an oil supply component, an atomization component, a sensing component, a power supply component and a button switch 10. The housing 20 has a receiving cavity 22, and an air inlet hole 21 communicating with the receiving cavity 22 is formed on the housing 20. Among them, the air inlet hole 21 can be arranged on the bottom surface or the side surface of the housing 20. The oil supply component, the atomization component, the sensing component and the power supply component are all installed in the receiving cavity 22, and the button switch 10 is installed in the air inlet hole 21. The sensing component is used to sense the change of the air pressure in the housing 20 to open and close the power supply component. The power supply component is connected to the atomization component and is used to supply power to the atomization component. The oil supply component is used to provide a liquid aerosol generating matrix of flower and leaf type, herb type and synthetic type for the atomization component. The atomization component is used to heat and atomize the aerosol generating matrix to form an aerosol. The aerosol is mixed with the air entering from the air inlet hole 21 and forms an aerosol mist, which is then output for the user to inhale. The button switch 10 is used to adjust the opening degree of the air inlet hole 21 to adjust the air intake amount of the air entering the housing 20, and thus the output aerosol mist amount can be adjusted to meet the needs of different users.

[0067] Specifically, the housing 20, the oil supply component, the atomization component, the sensing component and the power supply component are all conventional means in the art, so they will not be elaborated here. Next, the specific structure and working principle of the button switch 10 will be described in detail.

[0068] Please refer to Figures 8 to 12, the push-button switch 15 includes a base 11, a shift bracket 12, a guide bracket 13, an elastic member 14, and a button 15. The shift bracket 12 is mounted on the base 11. A plurality of shift slots 1211 of different gears are formed in the inner wall of the shift bracket 12. The shift slots 1211 of different gears are arranged along the circumferential direction of the shift bracket 12 and are connected in sequence. The guide bracket 13 is sleeved and installed inside the shift bracket 12. Guide teeth 131 are formed on the guide bracket 13 and are continuously arranged along the circumferential direction of the guide bracket 13. The elastic member 14 abuts between the base 11 and the guide bracket 13. The button 15 is exposed outside the air inlet hole 21. The button 15 is sleeved outside the guide bracket 13. The button 15 includes a pressing body 155 and a shift portion 151 protruding from the outer peripheral side of the pressing body 155. The shift portion 151 abuts against the tooth surface 1311 of the guide teeth 131. Among them, during the process that the button 15 is pressed and drives the guide bracket 13 to move towards the base 11, the button 15 rotates along the circumferential direction of the guide bracket 13 under the guiding action of the tooth surface 1311 of the guide teeth 131, so that the button 15 can be aligned with the shift slots 1211 of different gears, and the shift portion 151 is limited in the shift slot 1211 aligned with it by the elastic force of the elastic member 14. Specifically in the aerosol generating device 1, during the process that the button 15 is pressed and moves from the outside to the inside, an air inlet gap is formed between the outer side wall of the button 15 and the hole wall of the air inlet hole 21. The base 11 is connected to the housing 20. Among them, the base 11 and the housing 20 can be integrally provided, or can be fixedly connected to the housing 20 by means such as gluing, or can be detachably connected by means such as buckling and screwing. It can be specifically set according to needs and is not limited here.

[0069] Similarly, the base 11 and the shift bracket 12 can also be integrally provided, fixedly connected or detachably connected. For example, the base 11 and the shift bracket 12 are detachably buckled. As an example, the base 11 has a plurality of first buckling portions 111 arranged at intervals along its circumferential direction, and the shift bracket 12 has a plurality of second buckling portions 123 arranged along its circumferential direction. The first buckling portions 111 and the second buckling portions 123 correspond one by one, and the first buckling portions 111 and the second buckling portions 123 are buckled.

[0070] Please combine Figure 12 , Figure 18 and Figure 21 , the push-button switch 10 has multiple gear states. For example, the push-button switch 10 includes a first gear state, a second gear state, and a closed state, or the push-button switch 10 includes a first gear state, a second gear state, and a third gear state, etc. The gear state of the push-button switch 10 can be set according to requirements and is not limited here. When the push-button switch 10 is in different gear states, the shift portion 151 is limited in the shift slots 1211 of different gears.

[0071] Taking the button switch 10 including a first gear state, a second gear state and a closed state as an example, the shifting slot 1211 includes a first gear shifting slot 1211a, a second gear shifting slot 1211b and a closed shifting slot 1211c. When the button switch 10 is in the first gear state, the shifting part 151 is limited within the first gear shifting slot 1211a. When the button switch 10 is in the second gear state, the shifting part 151 is limited within the second gear shifting slot 1211b. When the button switch 10 is in the closed state, the shifting part 151 is limited within the closed shifting slot 1211c.

[0072] In some embodiments, all the shifting slots 1211 are continuously arranged along the circumferential direction of the shifting bracket 12 and enclose a closed-loop structure, and every two adjacent shifting slots 1211 communicate with each other, and the gear states corresponding to any two shifting slots 1211 are different. For example, taking the button switch 10 including a first gear state, a second gear state and a closed state, and the shifting bracket 12 having three shifting slots 1211 as an example, one of the shifting slots 1211 corresponds to the closed state, another shifting slot 1211 corresponds to the first gear state, and the third shifting slot 1211 corresponds to the second gear state. When the button 15 rotates one week, the first gear state, the second gear state and the closed state of the button switch 10 are all switched once.

[0073] In some embodiments, all the shifting slots 1211 are continuously arranged along the circumferential direction of the shifting bracket 12 and enclose a non-closed-loop structure. Every two adjacent shifting slots 1211 communicate with each other, and the gear states corresponding to any two shifting slots 1211 are different. For example, taking the button switch 10 including a first gear state, a second gear state and a closed state, and the shifting bracket 12 having three shifting slots 1211 as an example, it is defined that one of the shifting slots 1211 corresponds to the first gear state, another shifting slot 1211 corresponds to the second gear state, and the third shifting slot 1211 corresponds to the closed state. In the first rotation direction of the button 15, the shifting slot 1211 corresponding to the closed state, the shifting slot 1211 corresponding to the first gear state and the shifting slot 1211 corresponding to the second gear state are arranged in sequence. The button 15 rotates successively along the first rotation direction and passes through the shifting slot 1211 corresponding to the closed state, the shifting slot 1211 corresponding to the first gear state and the shifting slot 1211 corresponding to the second gear state, so that the button switch 10 can be sequentially switched from the closed state to the first gear state and the second gear state. When the button switch 10 needs to return to the closed state again, the button 15 can only rotate along the second rotation direction opposite to the first rotation direction, and after passing through the shifting slot 1211 corresponding to the first gear state and returning to cooperate with the shifting slot 1211 corresponding to the closed state, it can return to the closed state. In this embodiment, the rotation angles of the button 15 along the first rotation direction and the second rotation direction are both less than 360°.

[0074] In some embodiments, a plurality of shift groove groups 121 are formed on the inner wall of the shift bracket 12. The plurality of shift groove groups 121 are continuously arranged and communicated along the circumferential direction of the shift bracket 12, and each shift groove group 121 has shift grooves 1211 of multiple gears. Specifically, all the shift groove groups 121 are continuously arranged along the circumferential direction of the shift bracket 12 to form a closed-loop structure, and every two adjacent shift grooves 1211 in the same shift groove group 121 are communicated, and the adjacent two shift grooves 1211 in every two adjacent shift groove groups 121 are also communicated. The shift grooves 1211 of multiple gears are provided in the same shift groove group 121, and the shift grooves 1211 in the same shift groove group 121 correspond one-to-one to the gear states of the button switch 10. For example, assuming that the button switch 10 includes a first-gear state, a second-gear state, and a closed state, and the same shift groove group 121 has three shift grooves 1211, one of the shift grooves 1211 corresponds to the closed state, another shift groove 1211 corresponds to the first-gear state, and the third shift groove 1211 corresponds to the second-gear state. When the button 15 rotates one week, the first-gear state, the second-gear state, and the closed state of the button switch 10 alternate and cycle multiple times. This design can achieve 360° rotation of the button 15, and when the button 15 rotates one week, the states of the button switch 10 can be switched multiple times. The shifting is smooth without jamming, and the operation is convenient and simple.

[0075] For the convenience of description, the following embodiments will be described by taking the example that a plurality of shift groove groups 121 are formed on the inner wall of the shift bracket 12, the plurality of shift groove groups 121 are continuously arranged and communicated along the circumferential direction of the shift bracket 12, and each shift groove group 121 has shift grooves 1211 of multiple gears.

[0076] The wall surface of each shift groove 1211 facing the base 11 and farthest from the base 11 is defined as the groove top wall. There is a height difference in the axial direction of the shift bracket 12 between the shift grooves 1211 of different gears in the same shift groove group 121, which means that there is a height difference in the axial direction of the shift bracket 12 between the groove top walls of the shift grooves 1211 of different gears in the same shift groove 121. When the button switch 10 is in different gear states, the shifting part 151 is limited in the aligned shift groove 1211 by the elastic force of the elastic member 14 and abuts against the groove top wall of the shift groove 1211.

[0077] The guiding bracket 13 is used to guide the rotation of the button 15. Specifically, when the button 15 is pressed and drives the guiding bracket 13 to move towards the base 11, the tooth surface 1311 of the guiding bracket 13 guides the rotation of the button 15 so that the button 15 can be aligned with the shift grooves 1211 of different shift groove groups 121 or the shift grooves 1211 of different gears in the same shift groove group 121.

[0078] Combined with Figures 9 to 12, the guiding bracket 13 is movably connected to the shifting bracket 12. The guiding bracket 13 has freedom in the axial direction of the shifting bracket 12 relative to the shifting bracket 12, and the guiding bracket 13 may or may not have freedom in the circumferential direction of the shifting bracket 12 relative to the shifting bracket 12.

[0079] In some embodiments, a plurality of limiting grooves 122 are formed in the inner wall of the shifting bracket 12. All the limiting grooves 122 are arranged at intervals in the circumferential direction of the shifting bracket 12. The limiting grooves 122 are adjacent to the base 11 relative to the shifting groove group 121; a plurality of limiting portions 135 are formed on the guiding bracket 13. All the limiting portions 135 are arranged at intervals in the circumferential direction of the guiding bracket 13. The limiting portions 135 correspond to the limiting grooves 122 one by one, and the limiting portions 135 are limited in the corresponding limiting grooves 122.

[0080] When the limiting portion 135 is limited in the corresponding limiting groove 122, the detachable installation between the shifting bracket 12 and the guiding bracket 13 can be realized. And the limiting groove 122 is adjacent to the base 11 relative to the shifting groove group 121, which is beneficial to reducing the interference of the limiting portion 135 on the rotation of the button 15 during the rotation of the button 15, so that the button 15 can rotate smoothly.

[0081] Further, in some embodiments, the width of the limiting groove 122 in the circumferential direction of the shifting bracket 12 is slightly larger than the width of the limiting portion 135 in the circumferential direction of the shifting bracket 12. Therefore, in this embodiment, the guiding bracket 13 can rotate slightly in the circumferential direction of the shifting bracket 12 relative to the shifting bracket 12. Then, during the process that the button 15 is pressed and moves towards the base 11, the button 15 rotates under the guidance of the tooth surface 1311 of the guiding bracket 13. At the same time, under the reaction force of the guiding bracket 13, the guiding bracket 13 can be guided by the limiting groove 122 to rotate slightly, and the rotation direction of the guiding bracket 13 is opposite to the rotation direction of the button 15. In this case, a suitable gap can be formed between the groove wall of the shifting groove 1211 and the tooth surface 1311 of the guiding tooth 131 to facilitate the shifting portion 151. This method reduces the jamming feeling during the rotation of the button 15 and makes the rotation of the button 15 smoother.

[0082] Please refer to Figure 22As an example, the guide bracket 13 includes a first guide portion 132, a second guide portion 133 and a third guide portion 134. The first guide portion 132, the second guide portion 133 and the third guide portion 134 are all hollow cylindrical structures. The second guide portion 133 is sleeved outside the first guide portion 132 and connected to the first guide portion 132. The third guide portion 134 is sleeved outside the second guide portion 133 and connected to an end of the second guide portion 133 adjacent to the base 11. The limiting portion 135 protrudes from the side circumference of the third guide portion 134. The end surface of the third guide portion 134 facing away from the base 11 is structured to form a guide tooth 131. As an example, the guide bracket 13 may also include a first connecting portion and a second connecting portion. The first connecting portion is connected between the first guide portion 132 and the second guide portion 133, and the second connecting portion is connected between the second guide portion 133 and the third guide portion 134.

[0083] The elastic member 14 is used to provide elastic force, and the guide bracket 13 and the button 15 rebound with the help of the elastic force of the elastic member 14, so that the shifting part 151 is limited in the aligned shifting groove 1211.

[0084] The elastic member 14 may be elastic silicone, a spring or other components for providing elastic force. For example, the elastic member 14 is a compression spring, and the elastic member 14 is sleeved outside the first guide portion 132 and is located between the first guide portion 132 and the second guide portion 133.

[0085] The first guide portion 132 is used to support the elastic member 14 to reduce the risk of shaking during the deformation of the elastic member 14 and improve the reliability of the installation of the elastic member 14. In addition, the elastic member 14 is directly sleeved outside the first guide portion 132 and is located between the first guide portion 132 and the second guide portion 133, and abuts between the guide bracket 13 and the base 11 to complete the installation of the elastic member 14, which is convenient and reliable to install.

[0086] In some optional embodiments, for example, the air inlet 21 may be of an irregular shape. When the button 15 is pressed and rotated with the help of the guiding effect of the guide bracket 13, the gap between the button 15 and the hole wall of the air inlet 21 in the rotation direction gradually changes, so as to adjust the width of the air intake gap, thereby changing the air intake amount, and finally achieving the purpose of adjusting the air intake amount.

[0087] Combination Figures 1 to 7 , Figures 11 to 13 , and Figure 16, in some alternative embodiments, the button 15 is exposed outside the air inlet hole 21, and the aperture of the air inlet hole 21 gradually increases from outside to inside along the pressing direction of the button 15 (the axial direction of the shift bracket 12). During the process that the button 15 is pressed and moves from outside to inside, the gap between the outer sidewall of the button 15 and the hole wall of the air inlet hole 21 gradually increases. That is to say, when the button 15 is pressed and the moving distance along the pressing direction is different, the size of the gap between the button 15 and the hole wall of the air inlet hole 21 is different, and thus the air intake volume is also different. In this embodiment, there is a height difference in the axial direction of the shift bracket 12 between the shift slots 1211 of different gears in the same shift slot group 121. Therefore, the shift portion 151 needs to move different distances along the axial direction of the shift bracket 12 to abut against the top wall of the shift slots 1211 of different gears, so as to achieve gear shifting.

[0088] For the convenience of description, the following embodiments will be described by taking the example that there is a height difference in the axial direction of the shift bracket 12 between the shift slots 1211 of different gears in the same shift slot group 121.

[0089] It can be understood that the pressing body 155 is the main pressed part of the button 15, and the shift portion 151 is the main guided part of the button 15. When the pressing body 155 is pressed, it drives the shift portion 151 to move along the pressing direction, so that the shift portion 151 can be guided by the tooth surface 1311 of the guide tooth 131. Furthermore, the shift portion 151 can drive the pressing body 155 to rotate.

[0090] Combined with Figure 11 and Figure 12 , the button 15 may include one or more shift portions 151. For example, the button 15 has multiple shift portions 151, and all the shift portions 151 are arranged at intervals along the circumferential direction of the pressing body 155. It is worth mentioning that the number of the shift portions 151 should be less than or equal to the number of the shift slot groups 121. At the same time, different shift portions 151 on the button 15 cooperate with different shift slot groups 121. By setting multiple shift portions 151, it is beneficial to improve the stability and reliability of the cooperation between the shift bracket 12 and the button 15.

[0091] During actual operation, the position of the shift bracket 12 is fixed, and the button 15 is pressed to drive the guide bracket 13 to move towards the base 11 (this movement direction is the axial direction of the shift bracket 12), so as to increase the distance between the slot wall of the shift slot 1211 and the tooth surface 1311 of the guide tooth 131, so that the shift portion 151 can rotate under the guidance of the tooth surface 1311 of the guide tooth 131 through the gap between the slot wall of the shift slot 1211 and the tooth surface 1311 of the guide tooth 131. Furthermore, the shift portion 151 can be aligned with the shift slots 1211 of different gears.

[0092] Please refer to Figures 11 to 16, if the external force acting on the button 15 is relatively large, the guiding bracket 13 and the button 15 move a relatively large distance towards the base 11, resulting in a relatively large gap formed between the groove wall of the shifting groove 1211 and the tooth surface 1311 of the guiding tooth 131. During the rotation of the shifting portion 151, it only contacts the tooth surface 1311 of the guiding tooth 131 but does not contact the groove wall of the shifting groove 1211. In this case, when the external force is withdrawn, the guiding bracket 13 and the button 15 can rebound under the action of the elastic member 14, so that the shifting portion 151 can be limited within the aligned shifting groove 1211 and abut against the top wall of the aligned shifting groove 1211, thereby realizing the gear shift of the push button switch 10. In this operation mode, there is no wear between the shifting portion 151 and the groove wall of the shifting groove 1211 during the rotation process, which can extend the service life of the shifting bracket 12 and the button 15.

[0093] If the external force acting on the button 15 is relatively small, the guiding bracket 13 and the button 15 move a relatively small distance towards the base 11, resulting in a relatively small gap formed between the groove wall of the shifting groove 1211 and the tooth surface 1311 of the guiding tooth 131. During the rotation of the shifting portion 151, it contacts the tooth surface 1311 of the guiding tooth 131 and the groove wall of the shifting groove 1211. That is to say, during the rotation of the shifting portion 151, it is always clamped between the tooth surface 1311 of the guiding tooth 131 and the groove wall of the shifting groove 1211, and is limited within the aligned shifting groove 1211 and abuts against the groove wall of the aligned shifting groove 1211. In this case, when the external force is withdrawn, the guiding bracket 13 and the button 15 do not need to rebound to realize the gear shift of the push button switch 10. In this operation mode, under the combined action of the tooth surface 1311 of the guiding tooth 131 and the groove wall of the shifting groove 1211, the rotation of the shifting portion 151 is more stable.

[0094] Please refer to Figure 2 , Figure 9 and Figure 15 , in some embodiments, the external air can directly enter the accommodating cavity 22 through the gap between the outer side wall of the button 15 and the pore wall of the air inlet hole 21. In other embodiments, the side wall of the pressing body 155 is provided with a first through hole 152, the pressing body 155 has a ventilation cavity 153, the guiding bracket 13 has a second through hole 136, the shifting bracket 12 has a third through hole 124, and the base 11 is provided with a fourth through hole 112. The first through hole 152, the ventilation cavity 153, the second through hole 136, the third through hole 124 and the fourth through hole 112 are sequentially communicated to form an air inlet passage. The external air enters the accommodating cavity 22 through the gap between the outer side wall of the button 15 and the pore wall of the air inlet hole 21 and the air inlet passage in sequence.

[0095] It can be seen that by designing the button switch 10 in this application, when the button 15 is pressed, the button 15 is pressed down and can rotate under the guidance of the tooth surface 1311 of the guiding bracket 13, so as to realize the switching of different gears of the button switch 10, that is, the air intake of the aerosol generating device 1 can be adjusted. Compared with the sliding type, the pressing method is not easy to get stuck, and the operation is simple and convenient.

[0096] Please refer to Figures 11 to 23 In some alternative embodiments of the present application, the shift groove group 121 includes a closed shift groove 1211c, a first-gear shift groove 1211a, and a second-gear shift groove 1211b. During the rotation of the button 15, the shifting portion 151 is aligned with the closed shift groove 1211c, the first-gear shift groove 1211a, and the second-gear shift groove 1211b in sequence. The shift bracket 12 has a gear end face facing the base 11, and the shift groove 1211 has a groove top wall facing the base 11. Define the height from the groove top wall of the closed shift groove 1211c to the gear end face as H 0 , the height from the groove top wall of the first-gear shift groove 1211a to the gear end face is H 1 , the height from the groove top wall of the second-gear shift groove 1211b to the gear end face is H 2 , H 1 <H 2 <H 0 .

[0097] For the convenience of labeling and description, define the groove top wall of the first-gear shift groove 1211a as the first groove top wall 1211d, the groove top wall of the second-gear shift groove 1211 as the second groove top wall 1211e, and the groove top wall of the closed shift groove 1211c as the third groove top wall 1211f. In this embodiment, the button switch 10 has a closed state, a first-gear state, and a second-gear state. When the button switch 10 is in the closed state, the shifting portion 151 is clamped between the third groove top wall 1211f of the closed shift groove 1211c and the tooth surface 1311 of the guiding tooth 131. When the button switch 10 is in the first-gear state, the shifting portion 151 is clamped between the first groove top wall 1211d of the first-gear shift groove 1211a and the tooth surface 1311 of the guiding tooth 131. When the button switch 10 is in the second-gear state, the shifting portion 151 is clamped between the second groove top wall 1211e of the second-gear shift groove 1211b and the tooth surface 1311 of the guiding tooth 131.

[0098] Taking Figure 11 , Figure 12 and Figure 16 as an example, initially, the button switch 10 is in the closed state, and the shifting portion 151 abuts against the third groove top wall 1211f of the closed shift groove 1211c. When the button 15 is pressed inward, under the action of the guiding tooth 131 and the elastic member 14, the button 15 rotates clockwise (such as Figure 11Rotate as shown by arrow W so that the shifting part 151 reaches the position of the first-gear shifting groove 1211a, and the button switch 10 switches to the first-gear state (as Figures 17 to 19 shown). When the button 15 is pressed inward again, under the action of the guiding teeth 131 and the elastic member 14, the button 15 continues to rotate clockwise, and the shifting part 151 reaches the position of the second-gear shifting groove 1211b, and the button switch 10 switches to the second-gear state (as Figures 20 to 23 shown). Similarly, when the button 15 is pressed inward for the third time, the shifting part 151 reaches the position of the closed shifting groove 1211c, and the button switch 10 returns to the closed gear, and so on to achieve 360° rotation.

[0099] In this embodiment, the air intake volume when the button switch 10 is in the first-gear state is greater than that when it is in the second-gear state.

[0100] H 1 <H 2 <H 0 , so when the button switch 10 is initially in the closed gear, the button 15 is closest to the air inlet directly communicating with the outside of the air intake hole 21, which is convenient for pressing the button 15 and switching to the first-gear state. When the button switch 10 is in the first-gear state, during the whole process of switching from the first-gear state to the second-gear state and from the second-gear state to the closed state, the button 15 is pressed inward, or the distance of outward rebound and movement under the elastic action of the elastic member 14 gradually changes, which can improve the stability of the movement of the button 15.

[0101] In addition, the button switch 10 in the present application also has a closed state. When the aerosol generating device 1 switches to the closed state and stops working, foreign matters can be prevented from entering the inside of the aerosol generating device 1 to prevent the air intake hole 21 from being blocked.

[0102] Please refer to again Figure 11 and Figure 12 and Figures 16 to 23, in some alternative embodiments of the present application, the shift slots 121 correspond to the guiding teeth 131 one by one. The tooth surface 1311 of the guiding tooth 131 includes a tooth top curved surface 1311a and a tooth root curved surface 1311b. When the shifting part 151 is limited within the closed shift slot 1211c, the shifting part 151 abuts between the third slot top wall 1211f of the closed shift slot 1211c and the tooth top curved surface 1311a of the guiding tooth 131 corresponding to the closed shift slot 1211c. When the shifting part 151 is limited within the first-gear shift slot 1211a, the shifting part 151 abuts between the first slot top wall 1211d of the first-gear shift slot 1211a and the tooth root curved surface 1311b of the guiding tooth 131 corresponding to the first-gear shift slot 1211a. When the shifting part 151 is limited within the second-gear shift slot 1211b, the shifting part 151 abuts between the second slot top wall 1211e of the second-gear shift slot 1211b and the tooth root curved surface 1311b of the guiding tooth 131 corresponding to the second-gear shift slot 1211b.

[0103] Since the width of the limiting slot 122 in the circumferential direction of the shift bracket 12 is slightly larger than the width of the limiting part 135 in the circumferential direction of the shift bracket 12, during the rotation of the button 15, the guiding bracket 13 can rotate slightly relative to the shift bracket 12 under the reaction force of the button 15, so that when the shifting part 151 is limited within the first-gear shift slot 1211a and the second-gear shift slot 1211, it can abut against the tooth root curved surface 1311b of the guiding tooth 131.

[0104] In this embodiment, during the process of the button switch 10 switching from the closed state to the first-gear state, the shifting part 151 of the button 15 moves along the tooth side surface between the tooth top curved surface 1311a and the tooth root curved surface 1311b of the guiding tooth 131, having better movement stability.

[0105] In some embodiments, the tooth surface 1311 of the guiding tooth 131 further includes a tooth side surface connected between the tooth top curved surface 1311a and the tooth root curved surface 1311b. The shifting part 151 is a triangular prism structure, and one prism side surface thereof is arranged substantially parallel to one tooth side surface of the guiding tooth 131.

[0106] Wherein, the guiding tooth 131 has tooth side surfaces on both sides of the tooth top curved surface 1311a, and one prism side surface of the shifting part 151 is substantially parallel to one of the tooth side surfaces. Define the two tooth side surfaces of the guiding tooth 131 as the first tooth side surface 1311c and the second tooth side surface 1311d respectively. The first tooth side surface 1311c and the second tooth side surface 1311d are arranged along the rotation direction of the button 15. The first tooth side surface 1311c guides the rotation of the button 15, so that the button switch 10 switches from the second-gear state to the closed state, and the second tooth side surface 1311d guides the rotation of the button 15, so that the button switch 10 switches from the closed state to the first-gear state.

[0107] If the prism side surface of the shifting portion 151 is roughly parallel to the first tooth side surface 1311c, when the push button switch 10 is switched from the second gear state to the closed state, the prism side surface of the shifting portion 151 can roughly fit with the first tooth side surface 1311c, and under the guidance of the first tooth side surface 1311c, the tooth root curved surface 1311b of the guide tooth 131 slides toward the tooth top curved surface 1311a, thereby improving the stability of the movement of the button 15.

[0108] If the prism side surface of the shifting portion 151 is roughly parallel to the second tooth side surface 1311d, when the button switch 10 is switched from the off state to the first gear state, the prism side surface can roughly fit the second tooth side surface 1311d, and under the guidance of the second tooth side surface 1311d, the tooth top curved surface 1311a of the guide tooth 131 slides toward the tooth root curved surface 1311b, thereby improving the stability of the button 15 movement.

[0109] Please refer to Figure 3 、 Figure 5 、 Figures 7 to 9 , in some optional embodiments, the button switch 10 further includes a seal 16, which is disposed at one end of the pressing body 155 away from the shifting portion 151 and is disposed around the circumference of the pressing body 155. The seal 16 is used to seal the gap between the outer wall of the button 15 and the hole wall of the air inlet 21 when the shifting portion 151 abuts against the top wall of the closed shifting groove 1211c.

[0110] Initially, the button switch 10 is in the closed state, and the seal 16 seals the gap between the outer wall of the button 15 and the wall of the air inlet 21. When the button switch 10 is switched from the closed state to the first gear state, or from the first gear state to the second gear state, the seal 16 moves inward with the button 15. Since the aperture of the air inlet 21 gradually increases from the outside to the inside, when the button switch 10 is switched to the first gear state or the second gear state, the seal 16 separates from the wall of the air inlet 21 to achieve air intake. When the button switch 10 is switched back to the closed state, the seal 16 moves outward with the button 15 and reseals the button 15 and the wall of the air inlet 21.

[0111] By providing the sealing member 16, when the button switch 10 is in the closed state, the gap between the button 15 and the hole wall of the air inlet 21 can be better sealed, and foreign matter can be better prevented from entering.

[0112] Please refer to Figure 9 and Figure 22 , in some optional embodiments, the button 15 is provided with a positioning groove 154 arranged around the circumference thereof at one end away from the shifting portion 151, and the seal 16 is confined in the positioning groove 154. The positioning groove 154 is provided to facilitate the installation and positioning of the seal 16.

[0113] The above-mentioned push-button switch 10 and the aerosol generating device 1 are designed with the push-button switch 10. When the button 15 is pressed, the button 15 is pressed down and can rotate under the guidance of the tooth surface 1311 of the guiding bracket 13, so as to realize the switching of different gears of the push-button switch 10, that is, the air intake of the aerosol generating device 1 can be adjusted. Compared with the sliding type, the pressing method is not easy to get stuck, and the operation is simple and convenient.

[0114] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0115] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
