[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and benefits from a patent application bearing application number 202211525063.X, filed with the State Intellectual Property Office of China on November 30, 2022, the entire text of which is incorporated herein by reference.

[0002] The present application relates to the technical field of atomization devices, and more particularly to aerosol generating devices. [Background technology]

[0003] Aerosol generating devices, such as electronic atomizers, are popular with many users due to their low health risks and cost-effectiveness. Conventional aerosol generating devices typically use a heating assembly to heat an aerosol-generating medium and generate an aerosol for inhalation. However, during heating, the aerosol-generating medium is maintained in a stationary state, and the heating assembly heats only the stationary region of the aerosol-generating medium. Repeated heating of the stationary region over a long period of time can result in the generation of interfering gases in the stationary region, which can affect the mouthfeel of the aerosol. Summary of the Invention [Problem to be solved by the invention]

[0004] An embodiment of the present application provides an aerosol generating device. [Means for solving the problem]

[0005] The aerosol generating device according to an embodiment of the present application includes a frame, a rotating assembly attached to the frame, a heating assembly, and a drive assembly. The rotating assembly is used to rotate an aerosol generation medium including a plurality of medium portions, and the heating assembly corresponds to at least one of the medium portions and is used to heat the corresponding medium portion to generate an aerosol. The drive assembly is used to drive the rotating assembly and / or the heating assembly to rotate relative to the frame so as to switch the at least one medium portion corresponding to the heating assembly. [Effects of the Invention]

[0006] In the aerosol generating device according to the embodiment of the present application, the drive assembly drives the rotating assembly and / or the heating assembly to rotate relative to the frame so as to switch the medium portion of at least one aerosol generating medium corresponding to the heating assembly. Compared to the heating assembly heating a fixed region of the aerosol generating medium, the provision of the rotating assembly prevents the heating assembly from repeatedly heating the fixed region, thereby preventing the generation of interfering gases in the aerosol generating medium in the fixed region and ensuring a pleasant mouthfeel when the user inhales.

[0007] Additional aspects and advantages of the present application will be set forth in part in the description that follows, and in part will be obvious from the description, or may be learned by practice of the present application.

[0008] The above and / or additional aspects and advantages of the present application will become apparent and be readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings. [Brief explanation of the drawings]

[0016] Aerosol generating devices, such as electronic atomizers, are popular among many users due to their low health risks and cost-effectiveness. Conventional aerosol generating devices typically use a heating assembly to heat an aerosol-generating medium and generate aerosol for inhalation. However, because the heating assembly must be operated at a fixed heating time and frequency and only heats a fixed area of ​​the aerosol-generating medium, if the aerosol-generating medium is heated and the amount of aerosol generated is excessive or insufficient, the aerosol-generating medium cannot be adjusted. This not only affects the mouthfeel of the user when inhaling, but also leads to problems such as insufficient liquid supply and dry-burning of the heating assembly. Referring to FIG. 1 , to solve this problem, the present application provides an aerosol generating device 100.

[0017] 1 and 2, an aerosol generating device 100 according to an embodiment of the present application includes a frame 10, a rotating assembly 20 attached to the frame 10, a heating assembly 30, and a driving assembly 40. The rotating assembly 20 is used to rotate an aerosol generation medium 110 including a plurality of medium portions 1101. The heating assembly 30 corresponds to at least one of the medium portions 1101 and is used to heat the corresponding medium portion 1101 to generate an aerosol. The driving assembly 40 is used to drive the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10 so as to switch the at least one medium portion 1101 corresponding to the heating assembly 30.

[0018] The aerosol-generating medium 110 is an element capable of generating an aerosol through the action of heat, ultrasound, or mechanical vibration. An aerosol is a multiphase fluid in which a gas phase is the continuous phase and a solid or liquid phase is the dispersed phase. In some embodiments, the aerosol-generating medium 110 is a carrier for an atomization medium loaded with liquid tobacco tar. The tobacco tar is a liquid mixture containing dissolved substances such as nicotine, and the solute is a common organic and / or inorganic solute, such as propylene glycol, vegetable glycerin, or pure water. After being heated by the heating assembly 30, the tobacco tar disperses into fine droplets and mixes with air to form an aerosol. In other embodiments, the aerosol-generating medium 110 is a leaf atomization medium. After being heated by the heating assembly 30, the leaf atomization medium 110 volatilizes fine solid particles, which mix with air to form an aerosol. The aerosol-generating medium 110 includes a medium portion 1101 at a position corresponding to the heating assembly 30. The medium portion 1101 corresponds to the heating assembly 30 in the aerosol-generating medium 110 and is a portion that can generate aerosol when heated by the heating assembly 30. The cross-sectional shape of the medium portion 1101 may be, but is not limited to, a circle, a square, a sector, or the like.

[0019] In some embodiments, the cross-sectional shape of the medium portion 1101 may be, but is not limited to, a circle, a square, a sector, or the like. The reason why the medium portion 1101 corresponds to the heating assembly 30 is that it is heated by the heating assembly 30 to generate an aerosol. In one embodiment, when multiple medium portions 1101 of the aerosol-generation medium 110 have similar areas and shapes, and the rotating assembly 20 rotates relative to the frame 10, the heating assembly 30 corresponds to different medium portions 1101. By providing multiple similar medium portions 1101, the angle at which the drive assembly 40 drives the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10 is the same each time, which simplifies the control program for the drive assembly 40.

[0020] In another embodiment, the areas or shapes of the multiple medium portions 1101 of the aerosol-generating medium 110 may be different. For example, by providing multiple different medium portions 1101, such that one medium portion 1101 has an area of ​​1, another medium portion 1101 has an area of ​​2, and yet another medium portion 1101 has an area of ​​3, the aerosol generating device 100 can assign the heating assembly 30 to different medium portions 1101 depending on the user's inhalation habits (e.g., preference for first inhaling a small amount of aerosol and then inhaling a larger amount of aerosol). This prevents the aerosol-generating medium 110 from being heated to generate too much or too little aerosol, and ensures a pleasant mouthfeel for the user when inhaling. Note that in some embodiments, the flavor types of the aerosol-generating medium 110 corresponding to the multiple medium portions 1101 may be the same or different. If the aerosol-generating medium 110 corresponding to multiple medium portions 1101 has different flavor types, for example, the type of aerosol-generating medium 110 corresponding to one medium portion 1101 is mint flavor and the type of aerosol-generating medium 110 corresponding to another medium portion 1101 is jasmine flavor, when the heating assembly 30 corresponds to different medium portions 1101, the user can experience various types of flavors, thereby improving the usage experience.

[0021] In the aerosol generating device 100 of the present application, the driving assembly 40 drives the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10 so as to switch the medium portion 1101 of at least one aerosol-generating medium 110 corresponding to the heating assembly 30. By providing the rotating assembly 20, it is possible to avoid the generation of interfering gases in the fixed region of the aerosol-generating medium 110 caused by the heating assembly 30 repeatedly heating the fixed region, as compared to when the heating assembly 30 heats a fixed region of the aerosol-generating medium 110, and ensure a pleasant mouthfeel when the user inhales.

[0022] The aerosol generating device 100 will now be further described with reference to the accompanying drawings.

[0023] 1 and 2, in some embodiments, an aerosol generating device 100 includes a frame 10, a rotating assembly 20, a heating assembly 30, and a driving assembly 40. The rotating assembly 20, the heating assembly 30, and the driving assembly 40 are all attached to the frame 10. The rotating assembly 20 is used to mount an aerosol-generating medium 110. The heating assembly 30 is used to heat a corresponding medium portion 1101 to generate an aerosol for a user to inhale. The driving assembly 40 is used to drive the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10 so as to switch at least one medium portion 1101 corresponding to the heating assembly 30.

[0024] In some embodiments, when the aerosol generating device 100 is inhaled, the heating assembly 30 heats the currently corresponding at least one medium portion 1101. When the aerosol generating device 100 stops inhaling, the heating assembly 30 stops heating the currently corresponding at least one medium portion 1101, and the drive assembly 40 drives the rotation assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10 so as to switch the at least one medium portion 1101 corresponding to the heating assembly 30.

[0025] Specifically, when the aerosol generating device 100 is inhaled, the heating assembly 30 is activated to heat the currently corresponding medium part 1101, thereby heating the corresponding medium part 1101 and generating aerosol for inhalation by the user. When the aerosol generating device 100 stops inhaling, the heating assembly 30 stops heating the currently corresponding medium part 1101, and the driving assembly 40 drives the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10 so as to switch at least one medium part 1101 corresponding to the heating assembly 30. When the aerosol generating device 100 is next inhaled, the heating assembly 30 is restarted to heat the corresponding medium part 1101 after the switch.

[0026] In one embodiment, the drive assembly 40 may drive only the rotating assembly 20 to rotate relative to the frame 10, so as to switch at least one medium unit 1101 corresponding to the heating assembly 30. Compared to the drive assembly 40 driving both the rotating assembly 20 and the heating assembly 30 to rotate relative to the frame 10, driving only the rotating assembly 20 by the drive assembly 40 to rotate reduces wear on the drive assembly 40 during operation and avoids the problem of wires getting tangled when the heating assembly 30 rotates. In another embodiment, the drive assembly 40 may drive the heating assembly 30 to rotate relative to the frame 10, so as to switch at least one medium unit 1101 corresponding to the heating assembly 30. When the drive assembly 40 directly drives the heating assembly 30 to rotate, it is possible to ensure accurate correspondence between the heating assembly 30 and different medium units 1101 and improve the operating efficiency of the aerosol generating device 100. In this case, the heating assembly 30 can be wirelessly controlled, or the driving assembly 40 can be driven to rotate in a forward and reverse direction, thereby avoiding the problem of tangled wires during rotation of the heating assembly 30. In a further embodiment, the driving assembly 40 can drive both the rotating assembly 20 and the heating assembly 30 to rotate relative to the frame 10, so as to switch at least one medium unit 1101 corresponding to the heating assembly 30. The rotating speeds or directions of the rotating assembly 20 and the heating assembly 30 can be made different to ensure that the heating assembly 30 can accommodate different medium units 1101.

[0027] In some embodiments, the aerosol generating device 100 may be manually driven to rotate the rotating assembly 20 and / or the heating assembly 30 relative to the frame 10. That is, when suction to the aerosol generating device 100 is stopped, the heating assembly 30 stops heating the at least one medium unit 1101 currently associated with the heating assembly 30 and manually drives the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10 so as to switch the at least one medium unit 1101 associated with the heating assembly 30. Adopting a manual driving method can reduce the power consumption of the aerosol generating device 100 and simplify the configuration of the aerosol generating device 100. Furthermore, manual driving can also improve the enjoyment and user experience of the aerosol generating device 100.

[0028] 2 and 3 , in some embodiments, the frame 10 includes a first subframe 11 and a second subframe 13 attached to the top 113 of the first subframe 11. The rotating assembly 20 is attached to the top 135 of the second subframe 13. The heating assembly 30 is located between the rotating assembly 20 and the bottom 115 of the first subframe 11. A portion of the drive assembly 40 is located between the heating assembly 30 and the bottom 115 of the first subframe 11, and another portion is drilled into the heating assembly 30 and connected to the rotating assembly 20. When the drive assembly 40 drives the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10, the heating assembly 30 can correspond to different medium portions 1101 of the aerosol-generation medium 110 within the rotating assembly 20. In one embodiment, the frame 10 can be made of a metal material such as aluminum alloy or stainless steel, i.e., both the first sub-frame 11 and the second sub-frame 13 can be made of a metal material such as aluminum alloy or stainless steel, thereby improving the heat dissipation effect of the aerosol generating device 100 and ensuring normal operation of the aerosol generating device 100. In another embodiment, the frame 10 can be made of a plastic material such as PC or PCTG, i.e., both the first sub-frame 11 and the second sub-frame 13 can be made of a plastic material such as PC or PCTG, thereby reducing the weight of the frame 10 and further reducing the weight of the aerosol generating device 100. Of course, in other embodiments, one of the first sub-frame 11 and the second sub-frame 13 can be made of a metal material such as aluminum alloy or stainless steel, and the other can be made of a plastic material such as PC or PCTG.

[0029] In some embodiments, the first sub-frame 11 and the second sub-frame 13 can be connected by a removable attachment method such as screws or engagement, which facilitates assembly of the aerosol generating device 100 and improves production efficiency, while also allowing easy removal and repair or replacement of any malfunctioning device within the frame 10 (e.g., the rotating assembly 20, the heating assembly 30, the drive assembly 40, etc.). In other embodiments, the first sub-frame 11 and the second sub-frame 13 can be connected by a permanent attachment method such as welding, caulking, or adhesive, which ensures stable attachment between the first sub-frame 11 and the second sub-frame 13 and prevents the frame 10 from breaking or falling off during use of the aerosol generating device 100.

[0030] 2 and 3, in some embodiments, the rotating assembly 20 includes a base plate 21 and a tank cover 23. The base plate 21 is attached to the top of the frame 10. The tank cover 23 is attached to the top of the base plate 21 and together with the base plate 21 forms a storage tank 210 for storing the aerosol-generating medium 110.

[0031] Specifically, the base plate 21 is rotatably mounted on the top 135 of the second sub-frame 13, and the tank cover 23 is fitted onto the top of the base plate 21. In some embodiments, the base plate 21 and the tank cover 23 can both be made of polyetheretherketone (PEEK), which prevents deformation or damage to the base plate 21 and the tank cover 23 caused by high temperatures generated when the heating assembly 30 heats the aerosol-generating medium 110, thereby ensuring the safety of use of the aerosol generating device 100. Of course, in other embodiments, the base plate 21 and the tank cover 23 can be made of other high-temperature resistant materials, but the present invention is not limited thereto.

[0032] In one embodiment, the base plate 21 and the tank cover 23 may be connected by a removable attachment method such as a screw connection, bolts, or snap fit to facilitate replacement when the aerosol-generating medium 110 is depleted. In another embodiment, the base plate 21 and the tank cover 23 may be connected by a non-removable attachment method such as welding, caulking, or adhesive, thereby ensuring the stability of the operation of the rotating assembly 20.

[0033] In some embodiments, the heating assembly 30 is used to irradiate the at least one medium portion 1101 corresponding thereto, and the laser is used to heat the at least one medium portion 1101 corresponding to the heating assembly 30. The area of ​​the mounting plate 21 corresponding to the medium portion 1101 is a light-transmitting area 217 for passing the laser.

[0034] Specifically, when the aerosol-generating device 100 is inhaled, the heating assembly 30 is activated to emit a laser beam to the at least one corresponding medium portion 1101, thereby heating the at least one corresponding medium portion 1101 and generating an aerosol for inhalation by the user. When inhalation of the aerosol-generating device 100 is stopped, the heating assembly 30 stops emitting the laser beam. Simultaneously or thereafter, the driving assembly 40 drives the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10 so as to switch the at least one medium portion 1101 corresponding to the heating assembly 30. When the aerosol-generating device 100 is next inhaled, the heating assembly 30 is restarted to heat the switched-over medium portion 1101. Compared to resistance heating and electromagnetic induction heating methods, the use of a laser heating method can shorten the preheating time required for the heating assembly 30 to heat the aerosol-generating medium 110, thereby improving the aerosol generation rate of the aerosol-generating medium 110. As a result, the aerosol generating device 100 can ensure the freshness of the aerosol generated each time the user inhales, improving the mouthfeel when the user inhales, while also achieving the effect of being able to suck freely and improving the user's inhalation experience.

[0035] In some embodiments, the light-transmitting region 217 may be a light-transmitting solid region. That is, the light-transmitting region 217 may be made of a light-transmitting material such as glass or resin, thereby ensuring that the laser emitted from the heating assembly 30 passes through the light-transmitting region 217 to heat the corresponding medium portion 1101 and reducing laser loss along the propagation path. In one embodiment, the light-transmitting region 217 of the mounting plate 21 is made of a light-transmitting material, and the remaining region is made of a light-non-light-transmitting material, thereby preventing the laser from irradiating other medium portions 1101 and ensuring the amount of aerosol generated during the next suction. In another embodiment, the mounting plate 21 is made entirely of a light-transmitting material, thereby ensuring normal passage of the laser while also allowing the user to observe the remaining amount of aerosol-generating medium 110 and the aerosol generation status through the mounting plate 21.

[0036] In one embodiment, the aerosol-generation medium 110 may be placed directly on the bottom of the support plate 21, with the plurality of medium portions 1101 of the aerosol-generation medium 110 each abutting the light-transmitting region 217, thereby shortening the distance between the heating assembly 30 and the corresponding medium portion 1101 and ensuring the heating efficiency of the heating assembly 30. Furthermore, placing the aerosol-generation medium 110 directly on the bottom of the support plate 21 facilitates the installation and replacement of the aerosol-generation medium 110, thereby improving the assembly efficiency of the aerosol generating device 100. In another embodiment, the aerosol-generation medium 110 may be attached to the side wall of the base plate 21 by a mounting member (not shown). In this case, the plurality of medium portions 1101 of the aerosol-generation medium 110 are spaced apart from the light-transmitting regions 217. This prevents the bottom of the base plate 21 from being burned when the heating assembly 30 heats the corresponding medium portions 1101, thereby ensuring the safety of the aerosol generating device 100. In some embodiments, the mounting member may be made of polyetheretherketone (PEEK) or other high-temperature resistant materials.

[0037] 2 , in some embodiments, the rotating assembly 20 may further include a carrier 25. The carrier 25 is housed in the storage tank 210 and fixed between the mounting base 21 and the tank cover 23. The carrier 25 is used to mount the aerosol-generating medium 110 so as to space the aerosol-generating medium 110 from the bottom of the mounting base 21, and the area of ​​the carrier 25 corresponding to the medium portion 1101 is a light-transmitting area 251 for passing a laser.

[0038] Specifically, the carrier 25 may be placed directly on the bottom of the carrier 25, or may be fixed between the base plate 21 and the tank cover 23 by an attachment member (not shown). The aerosol-generating medium 110 is placed on the side of the carrier 25 opposite the bottom of the base plate 21, thereby separating the aerosol-generating medium 110 from the bottom of the base plate 21. The area of ​​the carrier 25 corresponding to the medium portion 1101 is made into a light-transmitting area 251 for transmitting a laser, so that the laser can pass through the base plate 21 and the carrier 25 and heat the aerosol-generating medium 110. In some embodiments, the carrier 25 may be made of polyetheretherketone (PEEK) or other high-temperature resistant material.

[0039] In one embodiment, the light-transmitting region 251 on the carrier 25 is a light-transmitting solid region. That is, the light-transmitting region 251 may be made of a light-transmitting material such as glass or resin, thereby ensuring that the laser emitted from the heating assembly 30 passes through the light-transmitting region 251 to heat the corresponding medium portion 1101 and reducing laser loss along the propagation path. In one example, the light-transmitting region 251 of the carrier 25 is made of a light-transmitting material, and the remaining region is made of a non-light-transmitting material, thereby preventing the laser from irradiating other medium portions 1101 and ensuring the amount of aerosol generated during the next inhalation. In another example, the entire carrier 25 is made of a light-transmitting material, thereby ensuring normal passage of the laser. In another embodiment, the light-transmitting area 251 on the carrier 25 is a light-transmitting window area, i.e., the light-transmitting area 251 is a through-hole that penetrates the carrier 25, which can further reduce the loss of the laser while passing through the carrier 25 and ensure the heating efficiency of the heating assembly 30.

[0040] In some embodiments, the carrier 25 has multiple mounting areas 252, each corresponding to one medium portion 1101, and between each of the medium portions 1101 and the mounting plate 21, a chamber 220 (shown in FIG. 6) is formed for containing the aerosol generated by the medium portion 1101.

[0041] Specifically, the aerosol-generating medium 110 is placed on the carrier 25, and each medium portion 1101 corresponds to one of the placement areas 252. The medium portions 1101, the placement board 21, and the placement areas 252 corresponding to the medium portions 1101 together form a chamber 220. The aerosol generated when the corresponding medium portion 1101 is heated by the heating assembly 30 is all contained in the corresponding chamber 220. The peripheral walls of the chambers 220 prevent the aerosol from entering other chambers 220. This prevents the aerosol generated when the corresponding medium portion 1101 is heated by the heating assembly 30 from spreading throughout the storage tank 210 when the aerosol-generating device 100 is inhaled. This ensures a sufficient amount of aerosol for each inhalation, providing a satisfying inhalation experience for the user, while also ensuring freshness of the aerosol generated the next time the user inhales, improving the mouthfeel.

[0042] 2 and 6 , in some embodiments, the outer shape and size of the carrier 25 are the same as the inner shape and size of the mounting plate 21, and each mounting area 252 has the same shape and size as the corresponding medium portion 1101. This ensures the hermeticity of the chamber 220 formed by the medium portion 1101, the corresponding mounting area 252, and the mounting plate 21, and prevents aerosols generated when the medium portion 1101 is heated from entering or leaking into other chambers 220. Specifically, in this embodiment, the carrier 25 includes an inner ring 253, an outer ring 254, and a plurality of connecting arms 255 connecting the inner ring 253 and the outer ring 254. The plurality of connecting arms 255 divide the carrier 25 into a plurality of mounting areas 252, each corresponding to a medium portion 1101. A chamber 220 is formed between each medium portion 1101 and the mounting plate 21. Specifically, two adjacent connecting arms 255, an inner ring sidewall 2531 between the two adjacent connecting arms 255, an outer ring sidewall 2541 between the two adjacent connecting arms 255, and the medium 1101 surround one chamber 220. In addition, one chamber 220 can prevent aerosol from entering another chamber 220, thereby ensuring freshness of the aerosol generated with each inhalation and improving the mouthfeel when inhaling.

[0043] 2, in some embodiments, the mounting base 21 may further include a stopper block 218. The carrier 25 may further include a relief opening 256. When the carrier 25 is mounted on the mounting base 21, the stopper block 218 fits into the relief opening 256, thereby facilitating the positioning and mounting of the carrier 25.

[0044] 2, in some embodiments, the heating assembly 30 includes a support base 31, a circuit board 33, and a laser chip 35 attached to the circuit board 33. The support base 31 is housed within the frame 10. The circuit board 33 is connected to the support base 31. The laser chip 35 is used to emit a laser.

[0045] Specifically, the support base 31, circuit board 33, and laser chip 35 are all located between the rotating assembly 20 and the frame 10. The support base 31 may be housed in the frame 10 by means of adhesive bonding, welding, screw connection, interference fit, etc. The circuit board 33 is connected to the support base 31, and the laser chip 35 is attached to the side of the circuit board 33 facing the rotating assembly 20, with the radiating end facing the rotating assembly 20, thereby ensuring normal heating of the corresponding medium part 1101 by the heating assembly 30. The method of attaching the circuit board 33 and the laser chip 35 may be adhesive bonding, welding, screw connection, etc., but is not limited thereto.

[0046] In some embodiments, heating the corresponding medium portion 1101 with the laser chip 35 allows the aerosol-generating medium 110 to generate aerosol rapidly, thereby ensuring freshness of the aerosol with each inhalation by the user. In other embodiments, the heating assembly 30 may heat the medium portion 1101 using a rapid heating method such as plasma.

[0047] In some embodiments, the aerosol-generation medium 110 is in the form of a sheet and is housed within the rotating assembly 20 , and the direction of laser emission is substantially aligned with the rotation axis of the rotating assembly 20 .

[0048] Specifically, the sheet-shaped aerosol-generation medium 110 is stored in the storage tank 210 and includes multiple medium portions 1101. When the drive assembly 40 drives the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10, the heating assembly 30 can correspond to different medium portions 1101. In one embodiment, the laser emission direction and the rotation axis of the rotating assembly 20 are completely aligned, i.e., the laser emission direction is parallel to the rotation axis of the rotating assembly 20 or perpendicular to the upper or lower surface of the aerosol-generation medium 110. This ensures that the laser reaches the aerosol-generation medium 110 over the shortest distance, improving the heating efficiency of the heating assembly 30. This shortens the time required for the heating assembly 30 to heat the currently corresponding medium portion 1101 to generate aerosol when the aerosol-generating device 100 is inhaled, achieving a flexible inhalation effect and improving the user's inhalation experience. In another embodiment, the direction of the laser beam forms a small predetermined angle with the axis of rotation of the rotating assembly 20, where the small predetermined angle is 30° or less.

[0049] In some embodiments, each medium portion 1101 is a sheet-like configuration having a sector-shaped cross section. Note that in some embodiments, the areas of the medium portions 1101 may be the same or different, i.e., the sector angles of the cross sections of the medium portions 1101 may be the same or different.

[0050] In some embodiments, the aerosol-generation medium 110 is a cylindrical configuration drilled into the rotating assembly 20 , and the direction of laser emission is approximately perpendicular to the rotation axis of the rotating assembly 20 .

[0051] Specifically, the columnar aerosol-generation medium 110 includes multiple medium portions 1101, and at least a portion of the aerosol-generation medium 110 is stored in the storage tank 210. When the drive assembly 40 drives the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10, the heating assembly 30 can correspond to different medium portions 1101 of the aerosol-generation medium 110. In one embodiment, the laser emission direction is perpendicular to the rotation axis of the rotating assembly 20, ensuring that the laser reaches the aerosol-generation medium 110 in the shortest distance, improving the heating efficiency of the heating assembly 30. When the aerosol-generating device 100 is inhaled, the heating assembly 30 shortens the time required for the heating assembly 30 to heat the currently corresponding medium portion 1101 to generate an aerosol, achieving a suction-free effect and improving the user's inhalation experience. In another embodiment, the laser emission direction forms a predetermined small angle with the rotation axis of the rotating assembly 20. For example, the predetermined small angle is 30° or less.

[0052] In one embodiment, the support seat 31 may be made of a metal material such as aluminum alloy or stainless steel, which can avoid the problem of damage to the support seat 31 caused by heat generated during operation of the heating assembly 30 and ensure the normal operation of the aerosol generating device 100. In another embodiment, the support seat 31 may be made of a plastic material such as PC or PCTG, which can reduce the weight of the support seat 31 and make the aerosol generating device 100 lighter.

[0053] 1 and 3, in some embodiments, the heating assembly 30 may further include a heat dissipation member 37 mounted within the frame 10. The heat dissipation member 37 is used to dissipate heat from other elements within the heating assembly 30.

[0054] Specifically, the heat dissipation member 37 may be attached to the frame 10 by adhesive bonding, welding, engagement, or interference fit. At least a portion of the heat dissipation member 37 is mounted on the second sub-frame 13. The heat dissipation member 37 may be made of a high-temperature-resistant material with a fast heat conduction rate, such as, but not limited to, polyetheretherketone (PEEK), a high-melting-point metal, or a high-temperature-resistant ceramic. The heat dissipation member 37 can dissipate heat from the circuit board 33 and the laser chip 35, preventing them from overheating and causing damage during operation and ensuring the normal operation and safety of the aerosol generating device 100. In some embodiments, the heat dissipation member 37 may be one or more of a heat dissipation block 371, a heat dissipation fin, or the like. Of course, in other embodiments, the heat dissipation member 37 may be one or more of a heat dissipation fan, a heat dissipation pipe, or the like.

[0055] 4 and 5, in some embodiments, the heat dissipation member 37 includes a heat dissipation block 371, the circuit board 33 is connected to the support seat 31 via the heat dissipation block 371, and the heat dissipation block 371 is used to conduct heat generated by the laser chip 35 to the support seat 31 and the frame 10.

[0056] The heat dissipation block 371 includes a first side 3711 and a second side 3713, which face each other. The second side 3713 of the heat dissipation block 371 faces and can abut against the support seat 31. The circuit board 33 is mounted on the first side 3711 of the heat dissipation block 371. The cross-sectional shape and size of the heat dissipation block 371 are essentially the same as those of the second sub-frame 13. Therefore, when the heat dissipation block 371 is mounted in the second sub-frame 13, the side walls of the heat dissipation block 371 abut against the inner walls of the second sub-frame 13. This allows the heat generated by the laser chip 35 to be conducted to the frame 10 and the support seat 31 via the heat dissipation block 371 for dissipation. Furthermore, the cross-sectional shape and size of the heat dissipation block 371 are essentially the same as those of the second sub-frame 13, which increases the contact area between the heat dissipation block 371 and the second sub-frame 13 and improves the heat dissipation effect. In one embodiment, the heat dissipation block 371 and the support seat 31 may be connected by a removable attachment method such as a screw connection, a bolt, or a snap fit. In another embodiment, the heat dissipation block 371 and the support seat 31 may be connected by a non-removable attachment method such as welding, crimping, or adhesive.

[0057] In some embodiments, the circuit board 33 is directly placed on the first side 3711 of the heat dissipation block 371, and the second side 3713 of the heat dissipation block 371 abuts the frame 10, so that heat generated by the laser chip 35 is conducted to the support seat 31 and the frame 10 via the heat dissipation block 371. This mounting method also simplifies the assembly process of the heating assembly 30 and improves the assembly efficiency of the aerosol generation device 100. In another embodiment, the heat dissipation block 371 may include a recess 37111 recessed from the first side 3711 to the second side 3713 of the heat dissipation block 371. The circuit board 33 and the laser chip 35 are installed in the recess 37111. By installing the storage groove 37111, when the side walls of the circuit board 33 and / or the laser chip 35 are in contact with the side walls of the storage groove 37111, the contact area between the heat dissipation block 371 and the laser chip 35 is increased, the heat dissipation area is increased, and the heat dissipation effect of the heat dissipation block 371 is improved, while the focal length of the laser chip 35 can be easily adjusted and the heating efficiency of the laser chip 35 for the corresponding medium part 1101 can be improved.

[0058] In some embodiments, the heat dissipation member 37 may further include a heat dissipation boss 37131 disposed on the second side 3713 of the heat dissipation block 371 and capable of contacting the support seat 31. The heat dissipation boss 37131 extends from the second side 3713 of the heat dissipation block 371 in a direction opposite to the heat dissipation block 371 and is drilled into the bottom 133 of the second sub-frame 13 to contact the support seat 31. The heat dissipation boss 37131 increases the heat dissipation area of ​​the heat dissipation member 37, improving the heat dissipation effect and ensuring the normal operation of the circuit board 33 and the laser chip 35.

[0059] In one embodiment, the heat dissipation boss 37131 and the support seat 31 may be connected by a removable attachment method such as a screw connection, a bolt, or a snap fit. In another embodiment, the heat dissipation boss 37131 and the support seat 31 may be connected by a non-removable attachment method such as welding, caulking, or adhesive. Specifically, the heat dissipation boss 37131 has a threaded hole 37135, and the support seat 31 has a through hole 311 (shown in FIG. 3 ). A screw passes through the through hole 311 of the support seat and is then tightened into the threaded hole 37135 of the heat dissipation boss 37131, thereby fixedly connecting the heat dissipation block 371 and the support seat 31. When the aerosol generation device 100 is operating, rattle of the heat dissipation member 37 may cause noise in the aerosol generation device 100 or deviation of the laser direction of the laser chip 35. Therefore, the fixed connection between the heat dissipation member 37 and the support seat 31 ensures the stability of the heat dissipation member 37, prevents noise from occurring, and ensures the heating efficiency of the laser chip 35.

[0060] 2 and 3, the drive assembly 40 includes a drive member 41 and a connecting member 43. The drive member 41 is located between the heating assembly 30 and the bottom of the frame 10. The connecting member 43 is drilled into the heating assembly 30.

[0061] In one embodiment, the driving member 41 is used to drive the heating assembly 30 to rotate relative to the frame 10, and its output shaft 411 can be connected to the heating assembly 30 by a connecting member 43. Specifically, the driving member 41 is housed within the frame 10 and is located between the heating assembly 30 and the bottom 115 of the first sub-frame 11. When suction is applied to the aerosol generating device 100, the heating assembly 30 heats the currently corresponding medium part 1101. When suction to the aerosol generating device 100 is stopped, the output shaft 411 of the driving member 41 rotates, rotating the heating assembly 30 relative to the frame 10 and thereby switching the medium part 1101 corresponding to the heating assembly 30. In some embodiments, the driving member 41 can be a motor.

[0062] In another embodiment, the driving member 41 is used to drive the mounting plate 21 to rotate relative to the frame 10, and its output shaft 411 can be connected to the mounting plate 21 of the rotation assembly 20 by the connecting member 43. Specifically, when the aerosol generating device 100 is suctioned, the heating assembly 30 heats the currently corresponding medium unit 1101. When suction on the aerosol generating device 100 is stopped, the output shaft 411 of the driving member 41 rotates, rotating the mounting plate 21 relative to the frame 10 and switching the medium unit 1101 corresponding to the heating assembly 30. In one embodiment, when the mounting plate 21 rotates, the tank cover 23 and the mounting plate 21 both rotate relative to the frame 10. Compared to the mounting plate 21 rotating independently, the rotation of the tank cover 23 and the mounting plate 21 together can prevent friction between the tank cover 23 and the mounting plate 21 when the mounting plate 21 rotates independently, which can affect the sealing between the tank cover 23 and the mounting plate 21 over time. In another embodiment, when the base plate 21 rotates, the tank cover 23 is fixed relative to the base plate 21, and compared to when both the tank cover 23 and the base plate 21 rotate relative to the frame 10, the power consumption required for the drive member 41 to drive the rotating assembly 20 to rotate relative to the frame 10 is reduced, thereby extending the usage time of the aerosol generating device 100.

[0063] 2 and 3 , in some embodiments, the connecting member 43 includes a connecting shaft 431, a shaft sleeve 433, and a connecting element 435. The connecting shaft 431 is drilled through the second sub-frame 13 and the heat dissipation member 37, and one end thereof is connected to the output shaft 411 of the driving member 41. The shaft sleeve 433 is drilled through the mounting plate 21 and fitted onto the other end of the connecting shaft 431. The connecting element 435 fixedly connects the shaft sleeve 433 and the other end of the connecting shaft 431.

[0064] Specifically, the connecting shaft 431 is rotatably mounted in the second sub-frame 13 and the heat dissipation member 37, and the shaft sleeve 433 is mounted in the mounting plate 21 and fitted onto the other end of the connecting shaft 431. Thus, when the output shaft 411 of the driving member 41 rotates, the connecting shaft 431 rotates, causing the shaft sleeve 433 and the mounting plate 21 to rotate together relative to the frame 10, thereby switching the medium part 1101 corresponding to the heating assembly 30. Note that in some embodiments, the connecting element 435 may be a connecting member such as a screw or a bolt, but is not limited thereto.

[0065] In some embodiments, when the output shaft 411 of the driving member 41 is connected to the heating assembly 30 by the connecting member 43, the connecting shaft 431 is drilled through the second sub-frame 13 and the heat dissipation member 37, and one end of the connecting shaft 431 is connected to the output shaft 411 of the driving member 41, and the shaft sleeve 433 is drilled through the heat dissipation member 37 and fitted onto the other end of the connecting shaft 431. When the output shaft 411 of the driving member 41 rotates, the connecting shaft 431 rotates, causing the shaft sleeve 433 and the heat dissipation member 37 to rotate together with respect to the frame 10, thereby allowing the heating assembly 30 to correspond to different medium parts 1101.

[0066] 2 and 8 , in some embodiments, the aerosol generating device 100 may further include a suction nozzle 50 having one end inserted into the rotating assembly 20 and the other end exposed from the rotating assembly 20. The aerosol generating device 100 is provided with an intake passage 130, which is formed by the suction nozzle 50, the rotating assembly 20, a side wall 131 of the second sub-frame 13, and a medium part 1101 corresponding to the heating assembly 30. The intake passage 130 is used to allow the aerosol to flow out of the aerosol generating device 100.

[0067] Specifically, the end of the suction nozzle 50 inserted into the rotating assembly 20 communicates with the chamber 220 of the rotating assembly 20, allowing the aerosol in the chamber 220 to be inhaled by the user. An intake passage 130 is formed by the suction nozzle 50, the rotating assembly 20, the side wall 131 of the second sub-frame 13, and the medium part 1101 corresponding to the heating assembly 30. The intake passage 130 allows outside air to enter the rotating assembly 20, thereby balancing the air pressure inside and outside the rotating assembly 20 when the user inhales, and ensuring normal inhalation of the aerosol.

[0068] 6 and 7 , in some embodiments, the mounting board 21 includes a mounting plate 211, a first inner cylinder 212, a first outer cylinder 213, a second inner cylinder 214, and a second outer cylinder 215. The mounting plate 211 includes opposite first and second sides 2111 and 2113. The first inner cylinder 212 and the first outer cylinder 213 surrounding the first inner cylinder 212 extend from the first side 2111 of the mounting plate 211 in a direction away from the second side 2113 of the mounting plate 211. The second inner cylinder 214 and the second outer cylinder 215 surrounding the second inner cylinder 214 extend from the first side 2111 of the mounting plate 211 in a direction away from the first side 2111 of the mounting plate 211. The first inner cylinder 212 communicates with the second inner cylinder 214 via a through hole 2115 that penetrates the mounting plate, and also communicates with a through hole 231 in the tank cover. The first outer cylinder 213 is mounted on the top 135 of the second sub-frame 13. The outer size of the second outer cylinder 215 is smaller than the outer size of the first outer cylinder 213. The second outer cylinder 215 is inserted into the frame 10.

[0069] Specifically, the mounting plate 211 is located on the top 135 of the second sub-frame 13, the first inner cylinder 212 and the first outer cylinder 213 are located on a first side 2111 of the mounting plate 211, and the second inner cylinder 214 and the second outer cylinder 215 are located on a second side 2113 of the mounting plate 211. The aerosol-generating medium 110 is located between the first outer cylinder 213 and the first inner cylinder 212, and forms a plurality of chambers 220 together with the first outer cylinder 213 and the first inner cylinder 212. The first inner cylinder 212 and the second inner cylinder 214 communicate with each other via a through-hole 231 in the tank cover, and the second inner cylinder 214 is inserted into the second sub-frame 13. The shaft sleeve 433 is at least partially attached to the second inner cylinder 214 and connected to the connecting shaft 431. By making the outer size of the second outer cylinder 215 smaller than that of the first outer cylinder 213, the second outer cylinder 215 can be inserted into the second sub-frame 13, facilitating installation and positioning of the mounting plate 21. In some embodiments, the central axes of the first inner cylinder 212, the first outer cylinder 213, the second inner cylinder 214, and the second outer cylinder 215 may overlap. This ensures the stability of the mounting plate 21 when the drive assembly 40 drives the mounting plate 21 to rotate, preventing misalignment between the heating assembly 30 and the medium unit 1101 due to misalignment that occurs during rotation of the mounting plate 21, and ensuring normal operation of the aerosol generating device 100. In other embodiments, the central axes of the first inner cylinder 212, the first outer cylinder 213, the second inner cylinder 214, and the second outer cylinder 215 may not completely overlap. For example, the fact that the central axes of the first inner cylinder 212 and the second inner cylinder 214 do not overlap can prevent the first inner cylinder 212 or the second inner cylinder 214 from interfering with other components during assembly of the aerosol generating device 100, thereby ensuring normal assembly of the aerosol generating device 100. In some embodiments, the outer shapes of the first outer cylinder 213 and the second outer cylinder 215 may be circular, elliptical, rectangular, or the like, but are not limited thereto.

[0070] 2, 7 and 8, in some embodiments, the intake passage 130 includes the inner cavity 51 of the suction nozzle, the inner cavity 2121 of the first inner cylinder, a through hole 2123 on the side wall of the first inner cylinder 212, a chamber 220 corresponding to the heated medium portion 1101, a through hole 2151 extending from the outside of the second outer cylinder 215 to the first side 2111 of the mounting plate 211, and an intake hole 1311 on the side wall 131 of the second sub-frame 13. That is, when a user inhales, outside air enters the chamber 220 corresponding to the heated medium portion 1101 through the intake holes 1311 and through-holes 2151 on the side wall 131 of the second sub-frame 13, carrying the aerosol in the chamber 220 through the through-holes 2123 on the side wall of the first inner cylinder 212, the lumen 2121 of the first inner cylinder, and the lumen 51 of the suction nozzle, in that order, before being inhaled by the user. The side wall of the first inner cylinder 212 corresponding to each chamber 220 is provided with a through-hole 2123, and each chamber 220 is provided with a through-hole 2151. In some embodiments, the number of through-holes 2123 corresponding to each chamber 220 is one or more. Providing multiple through-holes 2123 can increase the amount of aerosol inhaled during inhalation and ensure a better inhalation experience for the user.

[0071] Referring to FIG. 6 , in some embodiments, the rotating assembly 20 may further include a first seal member 27. The first seal member 27 is fitted onto the second external cylinder 215 and is located between the side wall 131 of the second sub-frame 13 and the second external cylinder 215. A ventilation gap 270 is provided between the first seal member 27 and the side wall 131 of the second sub-frame 13. The first seal member 27 is provided with a through hole 271, which corresponds to and communicates with the through hole 2151 and is offset from the intake hole 1311 in the circumferential direction of the frame 10. The through hole 271 communicates with the intake hole 1311 via the ventilation gap 270. In this case, the intake passage 130 further includes the ventilation gap 270.

[0072] Specifically, the first sealing member 27 is located between the inner side of the side wall 131 of the second sub-frame 13 and the second outer cylinder 215, and a ventilation gap 270 is provided between the first sealing member 27 and the inner side of the side wall 131 of the second sub-frame 13, and the intake hole 1311 communicates with the ventilation gap 270. In one embodiment, the inner side of the side wall 131 of the second sub-frame 13 is recessed in a direction away from the first sealing member 27 to form the ventilation gap 270, and a through hole 271 is provided in the first sealing member 27 at a position corresponding to the ventilation gap 270, and the through hole 271 communicates with the intake hole 1311 through the ventilation gap 270, but the corresponding position is offset from the intake hole 1311, i.e., not aligned with the intake hole 1311. In another embodiment, the outer side of the first seal member 27 is recessed in a direction away from the side wall 131 of the second sub-frame 13 to form a ventilation gap, and a through hole 271 is further provided in the first seal member 27 at a position corresponding to the ventilation gap, and the through hole 271 communicates with the intake hole 1311 via the ventilation gap, and similarly, the corresponding position is offset from the intake hole 1311, i.e., not aligned with the intake hole 1311. In a further embodiment, the inner side of the side wall 131 of the second sub-frame 13 is recessed in a direction away from the first seal member 27 to form a first groove (not shown), and the outer side of the first seal member 27 is recessed in a direction away from the side wall 131 of the second sub-frame 13 to form a second groove (not shown). The combination of the first groove and the second groove forms a ventilation gap, with the intake hole 1311 aligned with and communicating with one end of the ventilation gap, and the through hole 271 aligned with and communicating with the other end of the ventilation gap, so that the through hole 271 is offset from the intake hole 1311 and communicates with the intake hole 1311 via the ventilation gap 270.

[0073] The intake passage 130 further includes a ventilation gap 270, i.e., the intake passage 130 includes the cavity 51 of the suction nozzle, the cavity 2121 of the first inner cylinder, a through-hole 2123 on the side wall of the first inner cylinder 212, a chamber 220 corresponding to the heated medium portion 1101, a through-hole 2151 extending from the outside of the second outer cylinder 215 to the first side 2111 of the mounting plate 211, a through-hole 271 in the first sealing member 27, the ventilation gap 270, and an intake hole 1311 on the side wall 131 of the second sub-frame 13. The misalignment of the through-hole 271 and the intake hole 1311 reduces and ultimately avoids the appearance of gas leakage from the aerosol generating device 100 due to backflow from the intake hole 1311 via the intake passage 130 when the generated aerosol is not completely sucked up. The first seal member 27 is used to seal the gap between the mounting plate 21 and the side wall 131 of the second sub-frame 13 to prevent leakage of the aerosol.

[0074] 2, 6, and 7, in some embodiments, the rotating assembly 20 may further include a second sealing member 28. The second sealing member 28 is fitted onto the tank cover 23 and is located between the mounting base 21 and the tank cover 23, and is used to seal the gap between the mounting base 21 and the tank cover 23. The provision of the second sealing member 28 prevents leakage of the aerosol, ensures a smooth mouthfeel when the user inhales, and prevents impurities such as external dust from entering the storage tank 210, thereby ensuring the purity of the aerosol.

[0075] In some embodiments, the tank cover 23 includes a tank cover plate 232, a flange 233, and a socket portion 234. The tank cover plate 232 includes opposing first and second sides 2321 and 2323. The tank cover plate 232 is inserted into a first outer cylinder 213 of the mounting base 21, and the second seal member 28 is fitted onto the outside of the tank cover plate 232 and is located between the first outer cylinder 213 and the tank cover plate 232. The flange 233 has an annular configuration extending outward from the first side 2321 of the tank cover plate and is placed on top of the first outer cylinder 213. The socket portion 234 is drilled in the first side 2321 of the tank cover plate and the second side 2323 of the tank cover plate, and the flange 233 surrounds the socket portion 234. The first inner cylinder 212 of the mounting base 21 is inserted into the socket portion 234 from the second side 2323 of the tank cover plate. One end of the suction nozzle 50 is inserted into the socket portion 234 from the first side 2321 of the tank cover plate, and the other end is exposed from the socket portion 234. The inner cavity of the suction nozzle 50 and the inner cavity of the first inner cylinder 212 are connected. By providing the flange 233, the attachment between the tank cover 23 and the mounting base 21 can be further stabilized. In addition, by placing the flange 233 on the top of the first outer cylinder 213, the seal between the mounting base 21 and the tank cover 23 can be further ensured.

[0076] In some embodiments, the suction nozzle 50 and the socket portion 234 are attached by a tight fit, thereby ensuring a tight seal between the suction nozzle 50 and the tank cover 23 and preventing aerosol leakage, thereby ensuring the amount of aerosol inhaled by the user and ultimately ensuring a comfortable mouthfeel when inhaling.

[0077] In some embodiments, a portion of the first inner cylinder 212 may be inserted into the socket portion 234, and the first inner cylinder 212 and the socket portion 234 may be attached by an interference fit, thereby ensuring a tight seal between the first inner cylinder 212 and the socket portion 234, preventing a problem in which aerosol enters other positions except for the chamber 220 (shown in FIG. 8 ) of the storage tank 210, thereby reducing the amount of aerosol inhaled by the user, and ensuring a comfortable mouthfeel when inhaling. In other embodiments, a seal member (not shown) may be further installed between the first inner cylinder 212 and the socket portion 234, thereby ensuring a tight seal between the first inner cylinder 212 and the socket portion 234.

[0078] 2 and 8, in some embodiments, the aerosol generating device 100 may further include a protective cover 60. The protective cover 60 is attached to the mounting base 21 and is used to cover the connection element 435 so as to block the flow of aerosol from the intake passage 130 to the connection element 435.

[0079] 6 , the protective cover 60 is attached to the first inner cylinder 212 and is used to cover the connecting element 435. When a user inhales, the protective cover 60 blocks contact between the connecting element 435 and the aerosol as the aerosol passes through the through-hole 2123 on the sidewall of the first inner cylinder 212 and the inner cavity 2121 of the first inner cylinder 212 to flow into the suction nozzle 50. This prevents corrosion of the connecting element 435 and other functional components caused by the aerosol, or prevents charred material from condensing on the connecting element 435 and other functional components, which could affect their normal operation. Therefore, installing the protective cover 60 prevents damage to the connecting element 435 and other functional components and ensures the normal operation of the connecting element 435 and other functional components (e.g., the drive assembly 40). Furthermore, since all charred material condensed by the aerosol is formed on the surface of the protective cover 60, cleaning is easy.

[0080] In some embodiments, protective cover 60 is made of a high-temperature and corrosion-resistant material, which can enhance the protective effect of protective cover 60 on connection element 435 and other components. In some embodiments, protective cover 60 may be made of at least one of hard rubber, soft rubber, soft-hard bonded rubber, metal, ceramic, or glass.

[0081] In one embodiment, the protective cover 60 and the first inner cylinder 212 are tightly fitted together, i.e., the protective cover 60 may be abutted against the inner wall of the first inner cylinder 212 by an interference fit, thereby ensuring the airtightness of the space formed by the protective cover 60, the first inner cylinder 212, and other components.

[0082] In another embodiment, the protective cover 60 is connected to the inner wall of the first inner tube 212 by at least one of adhesive, ultrasonic welding, or laser welding, thereby further improving the sealing of the protective cover 60 and improving the protective effect of the protective cover 60 against the connecting element 435 and other components.

[0083] In a further embodiment, the protective cover 60 is connected to the top of the shaft sleeve 433 by at least one of adhesive bonding, ultrasonic welding, or laser welding, so that the protective cover 60 and the shaft sleeve 433 form an integrated structure, thereby ensuring the protective effect of the protective cover 60 on the connecting element 435 and other components, and also facilitating the installation of the protective cover 60, simplifying the assembly process, and improving the assembly efficiency of the aerosol generating device 100.

[0084] 2 and 9, in some embodiments, the aerosol generation device 100 may further include a gas flow detection assembly 70. The gas flow detection assembly 70 is attached to the heating assembly 30 and is used to detect whether or not the aerosol generation device 100 is being inhaled. A detection gas flow path 140 is formed by the suction nozzle 50, the rotation assembly 20, and the gas flow detection assembly 70. The gas flow detection assembly 70 determines whether or not the aerosol generation device 100 is being inhaled based on the air pressure in the detection gas flow path 140.

[0085] Specifically, referring to FIG. 8 , when a user inhales through the suction nozzle 50, the air pressure in the detection gas flow path 140 gradually decreases relative to the external air pressure, forming a negative pressure. The gas flow detection assembly 70 detects this change in air pressure in the detection gas flow path 140 and determines that the aerosol generation device 100 is in an inhalation state. Accordingly, the control assembly 90 of the aerosol generation device 100 controls the heating assembly 30 to heat the corresponding medium portion 1101 to generate an aerosol. The generated aerosol passes through the intake passage 130 and is inhaled by the user. When the user stops inhaling, external air passes through the intake passage 130 and enters the detection gas flow path 140, causing the air pressure in the detection gas flow path 140 to become equal to the external air pressure. The gas flow detection assembly 70 detects that the air pressure in the detection gas flow path 140 changes to or returns to a positive pressure, thereby determining that the aerosol generation device 100 is in an inhalation-free state. In this case, the control assembly 90 controls the heating assembly 30 to stop heating the corresponding medium portion 1101, and controls the drive assembly 40 to switch the medium portion 1101 corresponding to the heating assembly 30, thereby driving the rotation assembly 20 and / or the heating assembly 30 to rotate. This allows the aerosol generating device 100 to achieve a suction-free effect, improving the user's experience.

[0086] 4, 5, 10, and 11, in some embodiments, the gas flow detection assembly 70 includes a support seat 71, a microphone head cover 73, and a microphone head 75, and the gas flow detection assembly 70 further includes a microphone head passage 710. The support seat 71 is attached to a first side 3711 of the heat dissipation block 371 and includes an opposing first side 713 and a second side 715. The support seat 71 is provided with a first passage 711 that penetrates the first side 713 and the second side 715 of the support seat, and one end of the first passage 711 is an annular opening 7111. The microphone head cover 73 is connected to the other end of the first passage 711 and is drilled inside the heat dissipation block 371, and a second passage 731 is provided to penetrate the microphone head cover 73 and communicate with the first passage 711. The microphone head passage 710 includes a first passage 711 and a second passage 731 , and the microphone head 75 is attached to the end of the microphone head cover 73 away from the support seat 71 and corresponds to the second passage 731 .

[0087] Specifically, at least a portion of the annular opening 7111 communicates with one end of the first passage 711. The microphone head cover 73 is drilled in the heat dissipation block 371. An end of the microphone head cover 73 located on the first side 3711 of the heat dissipation block 371 communicates with the first passage 711, an end of the microphone head cover 73 located on the second side 3713 of the heat dissipation block 371 is connected to the microphone head 75, and a second passage 731 passes through the microphone head cover 73. One side of the microphone head 75 abuts against the end of the second passage 731 that faces away from the support seat 71, and the opposite side of the microphone head 75 faces the bottom 115 of the first sub-frame 11. When gas in the microphone head passage 710 flows through the annular opening 7111 at one end of the first passage 711 and into the rotating assembly 20, the air pressure in the microphone head passage 710 changes. In this case, because the air pressure on either side of the microphone head 75 is different, the microphone head 75 can send a signal to the control assembly 90 (shown in FIG. 3 ), which can then control the activation of the heating assembly 30. In some embodiments, the microphone head 75 can be an air pressure sensor or the like.

[0088] In some embodiments, the microphone head 75 includes a contact terminal portion 751 and a main body portion 753. The gas flow detection assembly 70 further includes a gasket 77. The gasket 77 is disposed between the microphone head 75 and the microphone head cover 73, surrounds the second passage 731, and is used to seal one end of the microphone head passage 710. Specifically, the gasket 77 is disposed between the main body portion 753 of the microphone head 75 and the microphone head cover 73 to seal the connection between the microphone head 75 and the microphone head cover 73, thereby preventing the microphone head 75 from being unable to accurately detect the air pressure in the microphone head passage 710 due to gas leakage in the microphone head passage 710 and ensuring normal operation of the aerosol generating device 100 (shown in FIG. 1 ).

[0089] In some embodiments, the second side 3713 of the heat dissipation block 371 is recessed toward the first side 3711 of the heat dissipation block 371 to form a recess 37133, and the end of the microphone head cover 73 away from the support seat 71 and the main body 753 of the microphone head 75 are received in the recess 37133. In one embodiment, the size and shape of the recess 37133 are matched to the size and shape of the main body 753, i.e., the main body 753 of the microphone head 75 can be received exactly within the recess 37133 and can abut against one end of the second passage 731 of the microphone head cover 73. This further improves the sealing effect between the microphone head 75 and the frame 10 of the microphone head cover 73, ensuring the accuracy of air pressure detection in the microphone head passage 710 by the microphone head 75, while reducing the space occupied by the gas flow detection assembly 70 and achieving a more compact aerosol generation device 100.

[0090] Referring to FIG. 2, in some embodiments, the bottom 133 of the second sub-frame 13 is further provided with an escape hole 1331, and at least a portion of the terminal portion 751 of the microphone head 75 is located within the escape hole 1331.

[0091] 2, 6, 7, 9, and 11, in some embodiments, the rotating assembly 20 may further include a seal ring 29 fixedly connected to the mounting plate 21. The suction nozzle 50 communicates with the first inner cylinder 212. The mounting plate 21 is further provided with a gas flow guide hole 216, which extends from the side wall of the first inner cylinder 212 to the stopper block 218 and reaches the second side 2113 of the mounting plate 211. A vent hole 291 is provided to pass through the seal ring 29 and communicates with the gas flow guide hole 216. The microphone head passage 710 includes a first end 7101 and a second end 7103, the first end 7101 of which is an annular opening 7111 that is always in communication with the vent hole 291, and the microphone head 75 is installed at the second end 7103 of the microphone head passage 710. The detection gas flow path 140 includes the microphone head passage 710, the vent hole 291, the gas flow guide hole 216, the lumen 2121 of the first inner cylinder, and the lumen 51 of the suction nozzle.

[0092] The sealing ring 29 is installed on the second side 213 of the mounting plate and fitted onto the second inner cylinder 214. When the drive assembly 40 drives the mounting plate 21 to rotate relative to the frame 10, the sealing ring 29 rotates together with the mounting plate 21. While the mounting plate 21 rotates together with the sealing ring 29, the vent hole 291 always communicates with the gas flow guide hole 216, and the annular opening 7111 always communicates with the vent hole 291. Therefore, when a user inhales through the suction nozzle 50, gas in the microphone head passage 710 can flow out of the aerosol generating device 100 by sequentially passing through the annular opening 7111, the vent hole 291, the gas flow guide hole 216, the lumen 2121 of the first inner cylinder, and the lumen 51 of the suction nozzle. That is, the microphone head passage 710, the vent hole 291, the gas flow guide hole 216, the cavity 2121 of the first inner cylinder, and the cavity 51 of the suction nozzle form the detection gas flow path 140. This changes the air pressure in the microphone head passage 710, making detection by the microphone head 75 easier.

[0093] In some embodiments, an annular gas groove 293 is provided on the side of the seal ring 29 opposite the mounting base 21, corresponding to and communicating with the annular opening 7111. The annular opening 7111 is constantly in communication with the vent hole 291 via the annular gas groove 293. One end of the vent hole 291 is in communication with the gas flow guide hole 216, and the other end is in communication with the annular gas groove 293. The provision of the annular gas groove 293 allows the seal ring 29 to fit tighter with the annular opening 7111 when the seal ring 29 rotates relative to the frame 10, improving the sealing effect of the detection gas flow path 140 and ensuring the accuracy of air pressure detection by the microphone head 75.

[0094] 2, 12, and 13, in some embodiments, the aerosol generating device 100 may further include a decorative assembly 80. The decorative assembly 80 is attached to the rotating assembly 20. The decorative assembly 80 and the heating assembly 30 are located on opposite sides of the rotating assembly 20. The decorative assembly 80 is driven by an external force to rotate relative to the frame 10.

[0095] The decorative assembly 80 is attached to a first side 2111 of the mounting plate 211, the heating assembly 30 is attached to a second side 2113 of the mounting plate 211, and the decorative assembly 80 is rotatable relative to the frame 10 when driven by an external force. In one example, the decorative assembly 80 can be driven by a device such as an electric motor, a motor, or the like. In another example, the decorative assembly 80 is driven by a user applying a driving force to the decorative assembly 80.

[0096] In one embodiment, the decorative assembly 80 includes a decorative member 81. The decorative member 81 is fixedly connected to the socket portion 234. When the drive assembly 40 drives the rotating assembly 20 to rotate relative to the frame 10, the decorative member 81 rotates relative to the frame 10 in synchronization with the rotating assembly 20. Specifically, the decorative member 81 is located on the first side 2111 of the mounting plate 211 and fixedly fitted to the socket portion 234. When the drive assembly 40 drives the rotating assembly 20 to rotate relative to the frame 10, the decorative member 81 rotates relative to the frame 10 in synchronization with the rotating assembly 20. In other words, the decorative member 81 can rotate relative to the frame 10 when the user is not inhaling, which can increase the enjoyment of using the aerosol generating device 100.

[0097] In some embodiments, the decorative assembly 80 includes a decorative member 81 and a bearing 83. The decorative member 81 is attached to the socket portion 234 by the bearing 83 so as to fit over the socket portion 234. The decorative member 81 is secured to the outer ring of the bearing 83 by an interference fit, and the socket portion 234 is secured to the inner ring of the bearing 83 by an interference fit.

[0098] Specifically, the decorative element 81 is located on the first side 2111 of the mounting plate 211 and is rotatably fitted onto the socket 234 of the tank cover 23 by the shaft sleeve 433. The decorative element 81 is fastened to the outer ring of the bearing 83 by an interference fit, and the socket 234 is fastened to the inner ring of the bearing 83 by an interference fit, so that when the decorative assembly 80 is driven by an external force, the decorative element 81 can rotate relative to the socket 234.

[0099] In some embodiments, the one-sided interference between the decorative member 81 and the bearing 83 is 0.01 mm to 0.20 mm. The interference refers to the relationship between the tolerance range of a hole and a shaft that are the same basic size and fit together. The size of the interference determines the tightness of the fit. If the outer diameter of the bearing 83 is larger than the inner diameter of the decorative member 81, the difference between their maximum limit sizes is the maximum interference, and the difference between their minimum limit sizes is the minimum interference. The one-sided interference between the decorative member 81 and the bearing 83 is any one of 0.01 mm, 0.04 mm, 0.06 mm, 0.08 mm, 0.10 mm, 0.13 mm, 0.15 mm, 0.17 mm, 0.19 mm, and 0.20 mm, or any value between any two of these. If the one-sided interference between decorative member 81 and bearing 83 is less than 0.01 mm, the fit between decorative member 81 and bearing 83 will be insufficient, which could result in slippage between decorative member 81 and bearing 83 or the bearing 83 falling off from decorative member 81. If the one-sided interference between decorative member 81 and bearing 83 is 0.20 mm or more, it will be difficult or even impossible to attach decorative member 81 to bearing 83. Therefore, if the one-sided interference between decorative member 81 and bearing 83 is 0.01 mm to 0.20 mm, decorative member 81 will be properly attached to socket portion 234 and will rotate normally relative to socket portion 234, while preventing decorative member 81 from falling off during rotation and improving the stability of the entire structure. In some embodiments, the interference on one side between the socket portion 234 and the bearing 83 is set to 0.01 mm to 0.20 mm, and since the same effect as above can be obtained, it will not be described in detail in this specification.

[0100] In some embodiments, the decorative member is provided with a ringing ball cavity 810. The decorative assembly 80 further includes a ringing ball 85. The ringing ball 85 is housed in the ringing ball cavity 810. The ringing ball 85 is used to collide with the walls of the ringing ball cavity 810 to generate sound when the decorative member 81 rotates relative to the frame 10.

[0101] 1 and 3, in some embodiments, the aerosol generating device 100 may further include a control assembly 90. The control assembly 90 includes a motherboard 91, a power supply 93, and a button 95. The motherboard 91 and the power supply 93 are both installed in the first sub-frame 11 and located on the side of the support base 31 opposite the heat dissipation member 37. The power supply 93 can supply power to the motherboard 91 and other functional components. The motherboard 91 is used to control the operation of components such as the heating assembly 30 and the driving assembly 40. The button 95 is installed on the side wall 111 of the first sub-frame and is electrically connected to the motherboard 91. The button 95 is used to start and stop the aerosol generating device 100.

[0102] Specifically, the user presses the button 95 to activate the aerosol generating device 100. When the user starts inhaling, the gas flow detection assembly 70 detects a change in air pressure in the detection gas flow path 140 and sends a signal to the motherboard 91. The motherboard 91 controls the heating assembly 30 to heat the corresponding medium portion 1101 and generate an aerosol. When the user stops inhaling, the gas flow detection assembly 70 detects a change in air pressure in the detection gas flow path 140 and sends a signal to the motherboard 91. The motherboard 91 controls the heating assembly 30 to stop heating, while controlling the drive assembly 40 to drive the rotation assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10, thereby causing the heating assembly 30 to correspond to a different medium portion 1101. The cycle of the above steps continues until the user presses the button 95 again to stop the aerosol generating device 100.

[0103] 2 and 14, an embodiment of the present application further provides a control method for an aerosol generating device 100, which includes a frame 10, a rotating assembly 20 attached to the frame 10, a heating assembly 30, and a driving assembly 40. The control method includes: Step 01: When suction on the aerosol generating device 100 is detected, the heating assembly 30 heats the currently corresponding medium portion 1101; Step 03: when the suction stop of the aerosol generating device 100 is detected, the heating assembly 30 stops heating the currently corresponding medium portion 1101; Step 05 includes driving the driving assembly 40 to rotate the rotating assembly 20 and / or the heating assembly 30 relative to the frame 10 so as to switch the medium portion 1101 corresponding to the heating assembly 30.

[0104] The control method of the present embodiment can be realized by the aerosol generating device 100 of the present embodiment. Specifically, the heating assembly 30 can be used to realize the methods described in 01 and 03, and the driving assembly 40 can be used to realize the method described in 05. That is, as a heating device, when suction on the aerosol generating device 100 is detected, the heating assembly 30 can be used to heat the medium part 1101 currently corresponding to the heating assembly 30. Also, as a heating device, when suction on the aerosol generating device 100 is stopped, the heating assembly 30 can be used to stop heating the medium part 1101 currently corresponding to the heating assembly 30. The driving assembly 40 can be used to drive the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10 so as to switch the medium part 1101 corresponding to the heating assembly 30. The specific configuration of the aerosol generating device 100 has already been described in detail in the above embodiment, and will not be repeated here.

[0105] In the control method for the aerosol generating device 100 according to the embodiment of the present application, the driving assembly 40 drives the rotating assembly 20 and / or the heating assembly 30 to rotate relative to the frame 10, so as to switch the medium portion 1101 of at least one aerosol-generating medium 110 corresponding to the heating assembly 30. Compared to the heating assembly 30 heating a fixed region of the aerosol-generating medium 110, the installation of the rotating assembly 20 allows the heating assembly 30 to repeatedly heat the fixed region, which prevents the generation of stray gases in the aerosol-generating medium 110 in the fixed region and ensures a pleasant mouthfeel when the user inhales.

[0106] The technical features of the above-described embodiments may be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features of 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 to fall within the scope of the present disclosure. In addition, other embodiments may be obtained from the above-described embodiments, and structural and logical substitutions and changes may be made without departing from the scope of the present disclosure.

[0107] The above examples merely represent some embodiments of the present application described in more detail and should not be understood as limiting the scope of the patent. It should be noted that a person skilled in the art can make some modifications and improvements without departing from the concept of the present application, which also fall within the scope of protection of the present application. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
