Aerosol generation device

[0001] Priority information

[0002] This application claims priority and benefits to patent application No. 202423062298.7, filed with the China National Intellectual Property Administration on December 11, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of aerosol generation technology, and more specifically, to an aerosol generation apparatus. Background Technology

[0004] An aerosol generating device is a type of small electronic device that generates aerosols by heating an aerosol generating article using a non-combustible method. Aerosol generating devices typically have a loading port to accommodate the aerosol generating article inserted into the device. To close the loading port when the device is idle and prevent dust or foreign objects from entering, a closable dust cover is usually provided at the loading port. In related technologies, the dust cover automatically springs back as the aerosol generating article is removed using an elastic element, automatically closing the loading port. However, the elastic element and the moving structure of the dust cover are relatively complex and inconvenient to install, which remains a technical problem to be solved. Summary of the Invention

[0005] This application provides an aerosol generating apparatus.

[0006] The aerosol generating apparatus of this application includes a housing and a dust cover assembly. The housing has a loading hole for receiving an aerosol-generated article inserted into the housing. The dust cover assembly is disposed on the housing and includes a cover body, an elastic element, a first rotating shaft, and a second rotating shaft. The first rotating shaft is fixedly connected to the housing, and the second rotating shaft is rotatably mounted on the first rotating shaft. The cover body is rotatably mounted on the first rotating shaft, and the elastic element is mounted on the second rotating shaft and connected to the cover body. The elastic element is configured to undergo elastic deformation during the process of opening the loading hole as the cover body rotates relative to the housing under the action of an external force, and is configured to recover its elastic deformation when the external force is removed, so as to drive the cover body to rotate relative to the housing and close the loading hole.

[0007] In the installation process of the dust cover assembly, the aerosol generating device of this application can first assemble the second rotating shaft, the elastic element and the cover body, then pass the first rotating shaft through the second rotating shaft, and then install the dust cover assembly together on the housing, thereby improving the installation convenience of the dust cover assembly and helping to improve production efficiency.

[0008] In some embodiments, the housing includes a bracket having a first mounting hole and a cover having a second mounting hole. The first mounting hole and the second mounting hole are axially aligned with a first rotating shaft, which passes through the first mounting hole and the second mounting hole.

[0009] Thus, by having the first rotating shaft pass through the first mounting hole and the second mounting hole, the first rotating shaft can connect the bracket and the cover at the same time, thereby reducing assembly steps and simplifying the installation operation.

[0010] In some embodiments, the support includes a support portion having two first mounting holes axially opposite each other along a first pivot axis. The support portion encloses a support space, and the two ends of the first pivot axis pass through the two first mounting holes respectively to support the cover in the support space.

[0011] Thus, by passing through the two first mounting holes at both ends of the first rotating shaft, the cover is mounted in the bearing space, allowing the cover to rotate around the first rotating shaft in the bearing space, and the bearing part provides sufficient space for the cover to rotate.

[0012] In some embodiments, the elastic element includes a spiral portion and a movable end and a fixed end connected to the spiral portion. The spiral portion is sleeved on the second rotating shaft, the movable end is fixedly connected to the cover, and the fixed end abuts against the housing. The movable end is used to apply an elastic force to the cover to keep the cover in the closed loading hole position.

[0013] During the process of elastic deformation of the elastic element, the movable end rotates relative to the fixed end around the helical part. During the process of elastic element recovering elastic deformation, the movable end rotates in the opposite direction relative to the fixed end around the helical part.

[0014] In this way, the elastic element supports the cover and keeps the loading hole closed when no external force is applied. When the cover rotates relative to the shell under the action of external force, it drives the movable end to rotate, and the elastic element undergoes torsional elastic deformation. When the external force is removed, the elastic element returns to its deformation. Thus, the dust cover assembly can open the loading hole by the force of the aerosol generating device and realize that the cover automatically rebounds to close the loading hole when the aerosol generating device is removed, which improves the convenience of use and the degree of hygiene.

[0015] In some embodiments, when the loading hole is open, a first angle is formed between the movable end and the fixed end, and when the loading hole is closed, a second angle is formed between the movable end and the fixed end, wherein the first angle is smaller than the second angle.

[0016] Thus, the angle between the movable end and the fixed end increases as the movable end closes the loading hole with the rotation of the cover, and decreases as the movable end opens the loading hole with the rotation of the cover.

[0017] In some embodiments, the cover includes a first side and a second side facing away from each other. The first side faces the external environment of the housing when the loading hole is closed, and the second side has a perforation through which a movable end passes.

[0018] In this way, by passing the movable end through the perforation, the movable end is fixed to the second side of the cover, so that the movable end and the cover rotate synchronously with respect to the shell and the fixed end on the shell, and the cover can hide the elastic element, ensuring the aesthetic appearance.

[0019] In some embodiments, the movable end and the fixed end are respectively connected to the two ends of the spiral portion along the axial direction.

[0020] Thus, the axial distance between the movable end and the fixed end is relatively large, and the number of spring wire turns between the movable end and the fixed end of the helical part is relatively large, which is beneficial to improving the working load of the elastic element.

[0021] In some embodiments, the axial length of the helical portion is less than the axial length of the second shaft, and the axial length of the second shaft is less than the axial length of the first shaft.

[0022] In this way, since the axial length of the spiral part is less than the axial length of the second shaft, and the axial length of the second shaft is less than the axial length of the first shaft, structural interference is avoided, and the assembly of the first shaft, the second shaft and the elastic element is also facilitated.

[0023] In some embodiments, the cover includes a first cover and a second cover. The dust cover assembly also includes a first elastic element and a first pivot assembly connected to the first cover, and a second elastic element and a second pivot assembly connected to the second cover. Each of the first pivot assembly and the second pivot assembly includes a first pivot and a second pivot. The first pivot assembly and the second pivot assembly are spaced apart. The first cover and the second cover are used to fit together to jointly close the loading hole, and to rotate relative to the housing to move away from each other and open the loading hole.

[0024] Thus, by having the first and second covers rotate relative to the housing and open the loading hole under the actuation of the two rotating shaft groups and the two elastic elements respectively, the space required for the cover to move relative to the housing is reduced, making the structure more compact and improving space utilization.

[0025] In some embodiments, the aerosol generating device includes an adjustment assembly comprising a magnetic element and a sensing element. The magnetic element is disposed on a cover, and the sensing element is disposed on a housing. The sensing element is used to sense the magnetic field generated by the magnetic element. When the magnetic element rotates with the cover and closes the loading hole, the sensing element and the magnetic element cooperate to stop the aerosol generating device. When the magnetic element rotates with the cover and opens the loading hole, the sensing element and the magnetic element cooperate to turn the aerosol generating device on.

[0026] In this way, by rotating the magnetic component with the cover, the magnetic field generated by the magnetic component is changed. The sensing component senses the change in the magnetic field generated by the magnetic component, so that the aerosol generating device is in a stopped state when the cover closes the loading hole and in a turned-on state when the cover opens the loading hole. Thus, the aerosol generating device can automatically adjust to the state corresponding to the opening and closing state of the loading hole according to the magnetic field sensed by the sensing component, which improves the convenience of use.

[0027] In some embodiments, the housing includes a support, a first housing, and a second housing, the first housing and the second housing enclosing an internal space, the support being mounted in the internal space, a cover being mounted on the support, a sensor being mounted on the second housing, and a magnetic element being configured to approach the sensor when the loading hole is closed as the cover rotates, and to move away from the sensor when the loading hole is opened as the cover rotates.

[0028] In this way, the magnetic component rotates with the housing and forms a relatively fixed movement path relative to the sensing component, making the magnetic field signal sensed by the sensing component more stable when the loading hole is open and closed, thereby improving the reliability of the regulating component in regulating the state of the aerosol generating device.

[0029] In some embodiments, the aerosol generating apparatus includes a heating component electrically connected to an induction element, the heating component being used to heat the aerosol-generated product in the on state and to stop heating in the off state.

[0030] In this way, by electrically connecting the heating component and the sensing element, the aerosol generating product is heated when the machine is on and stopped when the machine is off. Thus, the aerosol generating device can start heating after the aerosol generating product is inserted into the loading hole and stop heating after the aerosol generating product is removed from the loading hole, which is convenient to use and has a high degree of safety.

[0053] Please refer to Figure 1. The aerosol generating device 100 is a structure capable of generating aerosols by applying resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, or mechanical vibration to the aerosol generating product 200. The aerosol generating product 200 is a plant leaf product that has been processed and heated to produce aerosols. The aerosol generating product 200 can be in a fully solid or semi-solid state. The aerosol generating product 200 can be prepared using processes such as rolling, slurry forming, die casting, or extrusion. The aerosol generating product 200 can be a cylindrical structure similar to a cigarette, or a sheet, strip, or block structure.

[0054] Aerosol generating article 200 is heated and atomized to form an aerosol. The aerosol can be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. Users can inhale the aerosol into their mouth, nasal cavity, or lungs through their mouth or nose. Aerosols inhaled into the user's respiratory system can be used for various purposes such as food, medicine, and health care.

[0055] Please refer to Figures 2-5. The aerosol generating apparatus 100 of this application embodiment includes a housing 10 and a dust cover assembly 20. The housing 10 has a loading hole 101 for receiving an aerosol generating article 200 inserted into the housing 10. The dust cover assembly 20 is disposed on the housing 10 and includes a cover body 21, an elastic element 22, a first rotating shaft 231, and a second rotating shaft 232. The first rotating shaft 231 is fixedly connected to the housing 10, and the second rotating shaft 232 is rotatably sleeved on the first rotating shaft 231. The cover body 21 is rotatably disposed on the first rotating shaft 231, and the elastic element 22 is disposed on the second rotating shaft 232 and connected to the cover body 21. The elastic element 22 is configured to generate elastic deformation during the process of opening the loading hole 101 as the cover body 21 rotates relative to the housing 10 under the action of an external force, and is configured to restore elastic deformation when the external force is removed, so as to drive the cover body 21 to rotate relative to the housing 10 and close the loading hole 101.

[0056] In the process of installing the dust cover assembly 20, the aerosol generating apparatus 100 of this application embodiment can first assemble the second rotating shaft 232, the elastic element 22 and the cover 21, then pass the first rotating shaft 231 through the second rotating shaft 232, and then install the dust cover assembly 20 together on the housing 10, thereby improving the ease of installation of the dust cover assembly 20 and helping to improve production efficiency.

[0057] Specifically, the aerosol generating device 100 includes a top 11 and a bottom 12 opposite to each other, and a sidewall 13 connecting the top 11 and the bottom 12. The top 11, bottom 12, and sidewall 13 may be formed on different structural components constituting the housing 10. For ease of explanation, the direction from the top 11 to the bottom 12 is defined as the top-to-bottom direction. The loading hole 101 penetrates the housing 10 of the top 11 in the vertical direction. The aperture and shape of the loading hole 101 match the outer contour shape and size of the aerosol generating article 200. For example, if the aerosol generating article 200 is a cylindrical structure as shown in FIG. 3, the loading hole 101 is a circular hole.

[0058] The housing 10 can be generally cylindrical, and a battery 50, a control component 60, a heating component 70, etc., can be installed inside it. The cross-sectional shape of the outer contour of the housing 10 includes, but is not limited to, a circle, an ellipse, a racetrack shape, a rectangle, a triangle, a regular polygon, a non-regular polygon, a combination of shapes, or other irregular shapes. This application only uses the near-elliptical cross-sectional shape of the outer contour of the housing 10 as an example, as shown in Figure 4.

[0059] As can be easily understood, referring to Figures 3 and 6, when the loading hole 101 is closed, the cover 21 maintains a horizontal or nearly horizontal posture to cover the loading hole 101. When the cover 21 is rotated to a vertical or nearly vertical posture, the loading hole 101 can be opened. The vertical direction is parallel to the aforementioned up and down direction, and the horizontal direction is perpendicular to the vertical direction.

[0060] Optionally, the elastic element 22 can be a spring sheet, a compression spring, a torsion spring, etc. The elastic element 22 can apply an elastic force to the cover 21 to support the cover 21 and maintain its horizontal posture to cover the loading hole 101.

[0061] Before use, the user can apply downward pressure to the cover 21 with the aerosol generating product 200 (or its carrier), causing the cover 21 to rotate downwards and open the loading hole 101. During this downward rotation, the elastic element 22 undergoes further elastic deformation. As the user aspirates the aerosol, the aerosol generating product 200 (or its carrier) abuts against the cover 21, keeping the elastic element 22 in a deformed state and accumulating elastic potential energy. When the aerosol generating product 200 is withdrawn from the loading hole 101, the force applied by the aerosol generating product 200 (or its carrier) to the cover 21 is removed, releasing the elastic potential energy of the elastic element 22 and pushing the cover 21 back to a horizontal position in the form of an elastic force. Thus, the dust cover assembly 20 automatically rebounds after the user aspirates, eliminating the need to manually close the loading hole 101, thereby improving ease of use and hygiene.

[0062] The second rotating shaft 232 is a hollow shaft, which is sleeved on the first rotating shaft 231. The second rotating shaft 232 is indirectly connected to the cover 21 through an elastic element 22, so that the cover 21 and the second rotating shaft 232 rotate synchronously relative to the housing 10 around the first rotating shaft 231. Optionally, the first rotating shaft 231 and the second rotating shaft 232 are coaxial, and the axial directions of the first rotating shaft 231 and the second rotating shaft 232 can form an angle with the vertical direction.

[0063] Optionally, the aerosol generating apparatus 100 further includes a receiving tube 30 for receiving an aerosol generating article 200 inserted into the housing 10. The top end of the receiving tube 30 forms an opening and faces the loading hole 101. The receiving tube 30 can extend from top to bottom into the aerosol generating apparatus 100 so that the aerosol generating article 200 can be inserted into the receiving tube 30 through the loading hole 101.

[0064] The rotation path of the cover 21 relative to the housing 10 avoids the receiving tube 30. When the loading hole 101 is closed, the cover 21 can block the opening between the loading hole 101 and the top opening of the receiving tube 30; when the loading hole 101 is open, the cover 21 avoids the receiving tube 30 radially, so that the top opening of the receiving tube 30 can be exposed through the loading hole 101.

[0065] Please refer to Figures 7 and 8. In some embodiments, the housing 10 includes a bracket 14 with a first mounting hole 141 and the cover 21 with a second mounting hole 211. The first mounting hole 141 and the second mounting hole 211 are axially aligned with the first rotating shaft 231, which passes through the first mounting hole 141 and the second mounting hole 211.

[0066] Thus, by having the first rotating shaft 231 pass through the first mounting hole 141 and the second mounting hole 211, the first rotating shaft 231 can simultaneously connect the bracket 14 and the cover 21, thereby reducing assembly steps and simplifying installation operations.

[0067] Specifically, the first rotating shaft 231 is fixedly connected to the bracket 14 in the first mounting hole 141, and rotatably connected to the first rotating shaft 231 in the second mounting hole 211. The cover 21 can rotate around the first rotating shaft 231 through the second mounting hole 211. The rotation direction of the cover 21 is parallel to the circumferential direction of the second mounting hole 211.

[0068] For example, the axis of the first rotating shaft 231 is perpendicular to the vertical direction, and the axis of the first rotating shaft 231 is defined as the front-back direction. The cover 21 can swing up and down around the first rotating shaft 231 during the opening and closing of the loading hole 101.

[0069] Optionally, the cover 21 includes a first side 216 and a second side 217 facing away from each other. When the loading hole 101 is closed, the first side 216 faces upward towards the cover 21, and the second side 217 faces downward away from the first side 216 and downward towards the cover 21.

[0070] A second mounting hole 211 may be formed on the second side 217.

[0071] Please refer to Figures 6-8. In some embodiments, the bracket 14 includes a support portion 142. The support portion 142 forms two first mounting holes 141 that are axially aligned along the first rotating shaft 231. The support portion 142 surrounds a support space 1420. The two ends of the first rotating shaft 231 pass through the two first mounting holes 141 respectively to mount the cover 21 in the support space 1420.

[0072] Thus, by passing through the two first mounting holes 141 at both ends of the first rotating shaft 231 in the axial direction, the cover 21 is mounted on the bearing space 1420, so that the cover 21 can rotate around the first rotating shaft 231 in the bearing space 1420, and the bearing part 142 provides sufficient space for the rotation of the cover 21.

[0073] Specifically, the support portion 142 is generally bowl-shaped or box-shaped, with an opening at its upper end. A first mounting hole 141 is formed at the end of the support portion 142 that surrounds the opening. The two first mounting holes 141 are aligned in the front-to-back direction. The cover 21 has two second mounting holes 211, which are also aligned in the front-to-back direction. The two ends of the first rotating shaft 231 are located at the front end and the rear end, respectively. The first rotating shaft 231 can pass through the first mounting hole 141 at the front end, the second mounting hole 211 at the front end, the second mounting hole 211 at the rear end, and the second mounting hole 211 at the rear end in sequence.

[0074] Optionally, the support 14 further includes a plug-in portion 143 connected to the support portion 142, the plug-in portion 143 having a through hole to connect the support space 1420 and the receiving tube 30. With the loading hole 101 open, the aerosol generating article 200 can sequentially pass through the loading hole 101, the support space 1420, the through hole of the plug-in portion 143, and be inserted into the receiving tube 30.

[0075] Please refer to Figures 8 and 10. In some embodiments, the elastic element 22 includes a spiral portion 221 and a movable end 222 and a fixed end 223 connecting the spiral portion 221. The spiral portion 221 is sleeved on the second rotating shaft 232. The movable end 222 is fixedly connected to the cover 21. The fixed end 223 abuts against the housing 10. The movable end 222 is used to apply an elastic force to the cover 21 so that the cover 21 is kept in the position of closing the loading hole 101.

[0076] During the process of elastic deformation of the elastic element 22, the movable end 222 rotates around the helical part 221 relative to the fixed end 223. During the process of elastic deformation of the elastic element 22, the movable end 222 rotates around the helical part 221 relative to the fixed end 223 in the opposite direction.

[0077] Thus, the elastic element 22 supports the cover 21 to keep the loading hole 101 closed when there is no external force. When the cover 21 rotates relative to the housing 10 under the action of external force, it drives the movable end 222 to rotate. The elastic element 22 undergoes torsional elastic deformation. When the external force is removed, the elastic element 22 returns to its deformation. Thus, the dust cover assembly 20 can open the loading hole 101 by the force of the aerosol generating product 200 being inserted, and realize that the cover 21 automatically rebounds to close the loading hole 101 when the aerosol generating product 200 is removed, which improves the convenience of use and the degree of hygiene.

[0078] Specifically, the diameter of the spiral part 221 matches the diameter of the second rotating shaft 232, and the spiral part 221 can be formed by spirally winding spring wire around the second rotating shaft 232. The spiral part 221 can be tightly assembled with the second rotating shaft 232 and fixedly connected to the cover 21 through the movable end 222, so that the spiral part 221, the second rotating shaft 232 and the cover 21 rotate synchronously.

[0079] The movable end 222 and the fixed end 223 can be spring wires integrally connected to the helical portion 221. The fixed end 223 and the movable end 222 are connected to the helical portion 221 and extend outward from the helical portion 221 respectively. Optionally, the movable end 222 and the fixed end 223 are bent away from the tail end of the helical portion 221.

[0080] Optionally, the fixed end 223 abuts against the bracket 14, and the bracket 14 forms a limiting surface 144. The limiting surface 144 abuts against the fixed end 223 to restrict the movement of the fixed end 223. Further, the limiting surface 144 can be a plane, and the tail end of the fixed end 223 can be bent into a hook shape within the same plane, forming surface contact or line contact with the limiting surface 144. The limiting surface 144 can be the inner wall surface of the bearing portion 142 that encloses the bearing space 1420.

[0081] Please refer to Figures 8 and 13. In some embodiments, when the loading hole 101 is open, a first included angle α is formed between the movable end 222 and the fixed end 223, and when the loading hole 101 is closed, a second included angle β is formed between the movable end 222 and the fixed end 223. The first included angle α is smaller than the second included angle β.

[0082] Thus, the included angle between the movable end 222 and the fixed end 223 increases as the movable end 222 closes the loading hole 101 with the rotation of the cover 21, and decreases as the loading hole 101 opens with the rotation of the cover 21.

[0083] Specifically, the fixed end 223 and the movable end 222 can extend outward along different tangential directions of the spiral portion 221, so that an angle is formed between the movable end 222 and the fixed end 223. During the process of elastic deformation of the elastic element 22, the movable end 222 rotates around the spiral portion 221 closer to the fixed end 223, and during the process of elastic deformation of the elastic element 22, the movable end 222 rotates around the spiral portion 221 away from the fixed end 223.

[0084] Referring to Figures 3 and 6, the bracket 14 can limit the direction of the supporting force applied to the fixed end 223 by the limiting surface 144. Optionally, the limiting surface 144 is a plane, and the direction in which the bracket 14 applies the supporting force to the fixed end 223 is perpendicular to the limiting surface 144. In this embodiment, the direction in which the limiting surface 144 applies the supporting force to the fixed end 223 forms an angle of less than 90° with the direction in which the movable end 222 rotates near the fixed end 223.

[0085] Please refer to Figures 8-10. In some embodiments, the cover 21 includes a first side 216 and a second side 217 facing away from each other. The first side 216 faces the external environment of the housing 10 when the loading hole 101 is closed. The second side 217 has a perforation 212, and the movable end 222 passes through the perforation 212.

[0086] Thus, by passing the movable end 222 through the perforation 212, the movable end 222 is fixed to the second side 217 of the cover 21, so that the movable end 222 and the cover 21 rotate synchronously with respect to the housing 10 and the fixed end 223 on the housing 10, and the cover 21 can hide the elastic element 22, ensuring the aesthetic appearance.

[0087] Specifically, the cover 21 is generally a plate-like or flat block structure, with the first side 216 and the second side 217 being opposite sides in the thickness direction of the cover 21. To ensure that the side of the cover 21 with the larger surface area covers the loading hole 101, with the loading hole 101 closed, the first side 216 and the second side 217 are opposite sides in the vertical direction, with the second side 217 facing the internal space 106 of the housing 10. Optionally, the second side 217 faces the bracket 14.

[0088] Optionally, the second side 217 has a through hole 212 and two second mounting holes 211, with the through hole 212 located between the two second mounting holes 211 in the front-rear direction. During the assembly of the dust cover assembly 20, the spiral portion 221 is fitted onto the second rotating shaft 232 and placed together with the second rotating shaft 232 between the two second mounting holes 211. The first rotating shaft 231 passes through one of the second mounting holes 211 and through the second rotating shaft 232, finally passing through the other second mounting hole 211. The two second mounting holes 211 can be provided on both sides of the cover body 21 in the front-rear direction.

[0089] Please refer to Figures 12 and 13. In some embodiments, the movable end 222 and the fixed end 223 are respectively connected to the two ends of the spiral portion 221 in the axial direction.

[0090] Thus, the axial distance between the movable end 222 and the fixed end 223 is relatively large, and the spiral part 221 has a large number of spring wire turns between the movable end 222 and the fixed end 223, which is beneficial to increasing the working load of the elastic element 22.

[0091] Specifically, the spiral part 221 can be spirally wound on the second rotating shaft 232 in a clockwise or counterclockwise direction. One of the movable end 222 and the fixed end 223 is the starting point of the spiral line of the spiral part 221, and the other is the ending point of the spiral line of the spiral part 221.

[0092] Please refer to Figures 8 and 13. In some embodiments, the axial length of the helical portion 221 is less than the axial length of the second rotating shaft 232, and the axial length of the second rotating shaft 232 is less than the axial length of the first rotating shaft 231.

[0093] Thus, since the axial length of the spiral part 221 is less than the axial length of the second rotating shaft 232, and the axial length of the second rotating shaft 232 is less than the axial length of the first rotating shaft 231, structural interference is avoided, and the assembly of the first rotating shaft 231, the second rotating shaft 232 and the elastic element 22 is also facilitated.

[0094] Specifically, the first rotating shaft 231, the second rotating shaft 232, and the helical part 221 are sequentially sleeved from the inside out. The axial length of the helical part 221 is less than the axial length of the second rotating shaft 232, and both ends of the second rotating shaft 232 extend beyond the corresponding ends of the helical part 221. The movable end 222 and the fixed end 223 are respectively located at the ends of the second rotating shaft 232 that extend beyond the helical part 221, which helps to increase the load on the elastic element 22. The axial length of the second rotating shaft 232 is less than the axial length of the first rotating shaft 231, and both ends of the first rotating shaft 231 extend beyond the second rotating shaft 232. The ends of the first rotating shaft 231 that extend beyond the second rotating shaft 232 pass through the first mounting hole 141 and the second mounting hole 211.

[0095] During the assembly of the dust cover assembly 20, the spiral portion 221 is fitted onto the second rotating shaft 232, and the movable end 222 passes through the through hole 212, fixing the movable end 222 relative to the cover body 21. The two ends of the second rotating shaft 232 are aligned axially with the second mounting hole 211, which is aligned with the first mounting hole 141 on the bracket 14. Finally, the first rotating shaft 231 is passed through the first mounting hole 141, the second mounting hole 211, and the first rotating shaft 231. It is understood that along the axial direction of the first rotating shaft 231, the end of the first rotating shaft 231 extends beyond the end of the second rotating shaft 232, and the end of the second rotating shaft 232 extends beyond the end of the spiral portion 221, which facilitates the completion of the above assembly operation.

[0096] Please refer to Figures 3 and 8. In some embodiments, the cover 21 includes a first cover 213 and a second cover 214. The dust cover assembly 20 also includes a first elastic member 224 and a first rotating shaft group 23 connected to the first cover 213, and a second elastic member 225 and a second rotating shaft group 24 connected to the second cover 214. The first rotating shaft group 23 and the second rotating shaft group 24 each include a first rotating shaft 231 and a second rotating shaft 232. The first rotating shaft group 23 and the second rotating shaft group 24 are spaced apart. The first cover 213 and the second cover 214 are used to fit together to jointly close the loading hole 101, and to rotate relative to the housing 10 to move away from each other and open the loading hole 101.

[0097] Thus, by the action of the first cover 213 and the second cover 214 respectively under the actuation of the two rotating shaft groups and the two elastic elements 22, the space required for the cover 21 to move relative to the housing 10 is reduced, making the structure more compact and improving the space utilization rate.

[0098] Specifically, the first cover 213 and the second cover 214 are separate structures. With the loading hole 101 closed, the first cover 213 and the second cover 214 are joined together in a horizontal or near-horizontal position. With the loading hole 101 closed, the first cover 213 and the second cover 214 can remain vertical or approximately vertical and face each other in the horizontal direction.

[0099] It is easy to understand that, compared to the cover 21 forming a plate surface to cover the entire loading hole 101, the space swept by the separate first cover 213 and second cover 214 during the rotation relative to the housing 10 can also be relatively independent, which is conducive to a compact structural design.

[0100] Optionally, the first cover 213 and the second cover 214 may cover a portion of the loading hole 101 with the same area. Further, the first cover 213 and the second cover 214 may be symmetrically arranged, and the projection of the geometric center of the loading hole 101 onto the cover 21 in the vertical direction may fall on the axis of symmetry of the first cover 213 and the second cover 214. Correspondingly, the first elastic element 224 and the second elastic element 225, the first rotating shaft group 23 and the second rotating shaft group 24 are all symmetrically distributed along the axis of symmetry of the first cover 213 and the second cover 214. The axial directions of the first rotating shaft group 23 and the second rotating shaft group 24 are parallel to each other.

[0101] The axial direction of the first rotating shaft group 23 and the second rotating shaft group 24 is defined as the front-back direction. The first rotating shaft group 23 and the second rotating shaft group 24 can be respectively set at opposite ends of the cover 21 in the left-right direction. When the first cover 213 and the second cover 214 rotate downward around the first rotating shaft group 23 and the second rotating shaft group 24 respectively, they separate from the middle of the first cover 213 and the second cover 214.

[0102] This design allows the aerosol generating product 200 to be inserted through the middle of the loading hole 101, applying a relatively even force to the first cover 213 and the second cover 214. Furthermore, when the aerosol generating product 200 is removed from the loading hole 101, the first elastic element 224 and the second elastic element 225 recover their elastic deformation in a relatively consistent manner, thus facilitating user operation and ensuring high structural reliability. In addition, using symmetrical or identical components also facilitates mass production.

[0103] In other embodiments, the areas covered by the first cover 213 and the second cover 214 of the loading hole 101 may be different. For example, the first cover 213 may cover one-third of the loading hole 101, while the second cover 214 may cover the remaining two-thirds. Accordingly, the first elastic element 224 and the second elastic element 225 may be configured with appropriate loads and positioned appropriately based on stress analysis.

[0104] Please refer to Figures 3, 5, and 8. In some embodiments, the aerosol generating device 100 includes an adjustment assembly 40, which includes a magnetic element 41 and a sensing element 42. The magnetic element 41 is disposed on the cover 21, and the sensing element 42 is disposed on the housing 10. The sensing element 42 is used to sense the magnetic field generated by the magnetic element 41. When the magnetic element 41 rotates with the cover 21 and closes the loading hole 101, the sensing element 42 and the magnetic element 41 cooperate to make the aerosol generating device 100 stop. When the magnetic element 41 rotates with the cover 21 and opens the loading hole 101, the sensing element 42 and the magnetic element 41 cooperate to make the aerosol generating device 100 start.

[0105] Thus, by rotating with the cover 21, the magnetic field generated by the magnetic component 41 is changed. The sensing component 42 senses the change in the magnetic field generated by the magnetic component 41, so that the aerosol generating device 100 is in a stopped state when the cover 21 closes the loading hole 101 and in a powered-on state when the cover 21 opens the loading hole 101. Therefore, the aerosol generating device 100 can automatically adjust to the state corresponding to the opening and closing state of the loading hole 101 according to the magnetic field sensed by the sensing component 42, which improves the convenience of use.

[0106] Specifically, the magnetic component 41 can be a permanent magnet, and the magnetic poles of the magnetic component 41 can be N poles or S poles, or N / S poles can be formed at both ends respectively.

[0107] Optionally, referring to Figure 10, the cover 21 has a receiving groove 215, in which the magnetic component 41 can be fixedly installed. The inner contour shape and size of the receiving groove 215 match the shape and size of the magnetic component 41. For example, the magnetic component 41 is square, and the receiving groove 215 is a square recess. Alternatively, the depth of the receiving groove 215 is slightly greater than or equal to the dimension of the magnetic component 41 along the groove depth direction, so that when the magnetic component 41 is received in the receiving groove 215, the surface of the magnetic component 41 does not exceed the opening of the receiving groove 215, thereby improving the structural compactness.

[0108] The sensing element 42 is a type of component capable of detecting a nearby magnetic field and converting the detected magnetic field into an electrical signal. For example, the sensing element 42 includes a Hall element.

[0109] Optionally, as shown in Figure 5, the aerosol generating device 100 has a control component 60 disposed within the housing 10. The control component 60 includes a main board (not shown) and a chip (not shown), with the chip disposed on the main board. The control component 60 is electrically connected to the sensor 42. After receiving the change in magnetic field sensed by the sensor 42, the chip controls the state change of the aerosol generating device 100.

[0110] Please refer to Figures 3, 5, and 6. In some embodiments, the housing 10 includes a support 14, a first housing 15, and a second housing 16. The first housing 15 and the second housing 16 enclose an internal space 106. The support 14 is mounted on the internal space 106. The cover 21 is mounted on the support 14. The sensor 42 is mounted on the second housing 16. The magnetic element 41 is configured to approach the sensor 42 when the loading hole 101 is closed by rotating the cover 21, and to move away from the sensor 42 when the loading hole 101 is opened by rotating the cover 21.

[0111] Thus, the magnetic component 41 rotates with the housing 10 and forms a relatively fixed movement path relative to the sensing component 42, making the magnetic field signal sensed by the sensing component 42 more stable when the loading hole 101 is open and closed, thereby improving the reliability of the adjustment component 40 in adjusting the state of the aerosol generating device 100.

[0112] Specifically, the support 14, the first shell 15, and the second shell 16 are fixedly connected to each other. The first shell 15 is located at the top 11 of the aerosol generating device 100, and the first shell 15 and the second shell 16 cover each other.

[0113] Optionally, referring to FIG8, the first housing 15 includes a cover plate 151 and a surrounding plate 152. The cover plate 151 has a loading hole 101 formed thereon, and the surrounding plate 152 is connected to the edge of the cover plate 151 and extends downward from the edge of the cover plate 151. The surrounding plate 152 can surround the cover plate 151. The surrounding plate 152 can extend partially to the second housing 16 and engage with the second housing 16.

[0114] The bracket 14 includes a support portion 142 and a connector portion 143. The top of the support portion 142 forms an opening, and a cover plate 151 can cover the opening of the support portion 142 and together with the support portion 142, form a support space 1420. The cover plate 152 can surround the outer peripheral surface of the top of the support portion 142 and is fixedly connected to the support portion 142. A dust cover assembly 20 can be mounted at the opening of the support portion 142, and the cover body 21 can rotate relative to the housing 10 within the support space 1420. When the loading hole 101 is closed, the cover body 21 blocks the opening of the support portion 142 from the loading hole 101. When the loading hole 101 is open, the opening of the support portion 142 is opposite to and communicates with the loading hole 101.

[0115] The internal space 106 defined by the second housing 16 may house a battery 50, a control assembly 60, a heating assembly 70, a receiving tube 30, etc. The receiving tube 30, when the loading hole 101 is open, is opposite to and communicates with the carrying space 1420 and the loading hole 101. The heating assembly 70 may be partially disposed on or inside the receiving tube 30, which provides a location for heating the aerosol-generated article 200. The insertion portion 143 extends at least partially into the internal space 106 defined by the second housing 16 and is inserted into the receiving tube 30.

[0116] The second shell 16 can be a semi-enclosed structure, forming the bottom 12 and sidewall 13 of the aerosol generating device 100. The sensing element 42 can be disposed on the sidewall 13. Optionally, the sidewall 13 of the second shell 16 partially extends between the outer peripheral surface of the support portion 142 and the surrounding plate 152, and the sensing element 42 is disposed on the sidewall 13 facing the support portion 142. The magnetic element 41 rotates with the cover 21 within the support space 1420.

[0117] Please refer to Figures 2, 3 and 5. In some embodiments, the aerosol generating apparatus 100 includes a heating component 70, which is electrically connected to the induction element 42. The heating component 70 is used to heat the aerosol generating article 200 when the machine is on and to stop heating when the machine is off.

[0118] Thus, by electrically connecting the heating component 70 to the sensing element 42, the aerosol generating product 200 is heated when the machine is on and stopped when the machine is off. Therefore, the aerosol generating device 100 can start heating after the aerosol generating product 200 is inserted into the loading hole 101 and stop heating after the aerosol generating product 200 is removed from the loading hole 101. It is convenient to use and has a high degree of safety.

[0119] Specifically, the heating component 70 is electrically connected to the control component 60. The control component 60 receives the magnetic field change sensed by the sensing element 42 and converts it into an electrical signal, which is then output to the heating component 70. The control component 60 controls the heating component 70 to heat when the magnetic element 41 and the sensing element 42 are close together, that is, when the loading hole 101 is open, and to stop heating when the magnetic element 41 and the sensing element 42 are far apart, that is, when the loading hole 101 is closed.

[0120] In some embodiments, the assembly steps for mounting the dust cover assembly 20 onto the housing 10 are as follows:

[0121] (1) As shown in Figure 12, the movable end 222 of the elastic member 22 is passed through the through hole 212, and the second rotating shaft 232 is inserted into the spiral part 221 to complete the assembly of the second rotating shaft 232, the elastic member 22 and the cover 21.

[0122] (2) As shown in Figure 10, place the cover 21 at the opening of the bracket 14, so that the first mounting hole 141 of the bracket 14 and the second mounting hole 211 on the cover 21 are aligned in the front-back direction, and the fixed end 223 of the elastic element 22 abuts against the limiting surface 144. Pass the first rotating shaft 231 through the first mounting hole 141, the second mounting hole 211 and the second rotating shaft 232. The two ends of the first rotating shaft 231 along its own axis are respectively fixed in the two first mounting holes 141, thus completing the assembly of the bracket 14 and the dust cover assembly 20.

[0123] (3) As shown in Figure 9, fasten the bracket 14 with the first shell 15 and the first shell 15 with the second shell 16 to complete the assembly of the dust cover assembly 20 and the shell 10.
