The cover assembly comprises a control member, a first cover member and a second cover member. The control member is provided with a through hole which is in communication with the outside. In the length direction of the aerosol generating device, the control member is configured to rotate to drive the first cover member and the second cover member to rotate, so as to switch the cover assembly between a first state and a second state.

Description

Technical Field

[0001] This application relates to the field of heated non-combustible technology, and more specifically, to an aerosol generating device. Background Technology

[0002] An aerosol generator is a small device that uses heat-not-burning (HNB) to heat aerosol-generating articles and produce aerosols. In an aerosol generator, the aerosol-generating article must be inserted into a loading chamber within the housing for heat treatment. After the aerosol-generating article is removed from the loading chamber, the chamber is directly connected to the external environment, making it susceptible to dust contamination. Currently, aerosol generators use a sliding cover assembly to control the connection between the external environment and the loading chamber. However, as aerosol generators trend towards miniaturization, the sliding cover assembly, requiring a large space to open, is no longer suitable for the miniaturization requirements of aerosol generators. Utility Model Content

[0003] This application provides an aerosol generating apparatus to at least solve the technical problem that the covering component occupies too much space in the aerosol generating apparatus.

[0004] The aerosol generating device of this application includes a housing and a covering assembly. The housing has an internal channel. The covering assembly includes a control component, a first covering component, and a second covering component. The control component has a through hole communicating with the outside. Along the length of the aerosol generating device, the control component is configured to rotate, thereby rotating the first and second covering components to switch the covering assembly between a first state and a second state. The reduced rotation angle required for each covering component decreases the unilateral rotation space required for the covering components in the second state of the aerosol generating device, thus meeting the miniaturization requirements of the aerosol generating device.

[0005] In some embodiments, when the first state switches to the second state, the first and second covering members rotate synchronously and move away from each other. In some embodiments, when the second state switches to the first state, the first and second covering members rotate synchronously and move closer to each other.

[0006] In some embodiments, the aerosol generating device further includes a support and a cover. The support is disposed within the housing and has a channel. The cover is disposed at one end opening of the housing and connected to the support and / or the housing. The control component is rotatably connected to the cover. Along the length of the aerosol generating device, the first cover and the second cover are rotatably disposed between the support and the cover.

[0007] In some embodiments, the control element includes a control body and a mating portion, the mating portion being connected to the control body, the through hole being provided in the control body, and the control body being rotatably connected to the cover shell. At least one of the first cover and the second cover includes a connecting body and a mating portion, the mating portion being connected to the connecting body, the connecting body being connected to the bracket, and the mating portion and the mating portion being rotatably engaged.

[0008] In some embodiments, the cover includes a top and a side portion surrounding the top, the side portion having a first opening, the housing having a through hole corresponding to the first opening, the control member further including a toggle part connected to the side wall of the control body, and extending out of the housing after at least partially passing through the first opening and the through hole, the toggle part being configured to move in the first opening when subjected to force, thereby driving the control member to rotate.

[0009] In some embodiments, when the toggle part is located at a first position of the first opening, the covering assembly is in a first state; when the toggle part is located at a second position of the first opening, the covering assembly is in a second state.

[0010] In some embodiments, the aerosol generating device further includes a heating element. The support includes a first support, a second support disposed on the first support, and a third support located below the second support. The cover is connectable to the first support. The heating element is connected to both the second support and the third support. The channel is disposed between the second support, the heating element, and the third support. The second support and / or the cover has a mounting portion. At least one of the first cover and the second cover further includes a rotating shaft and a covering portion. The rotating shaft is connected to the connecting body and rotatably connected to the mounting portion. The covering portion is connected to the connecting body. In the first state, at least a portion of the covering portion is located on the path communicating between the through hole and the channel; in the second state, at least a portion of the covering portion is located outside the path communicating between the through hole and the channel.

[0011] In some embodiments, the second bracket is provided with a limiting protrusion located on the rotation path of the covering part, and the limiting protrusion is used to limit the rotation angle of the covering part.

[0012] In some embodiments, the cover is provided with a second opening, which is located on the rotation path of the covering portion of the first cover member and is used to allow at least a portion of the covering portion of the first cover member to pass through the cover body.

[0013] In some embodiments, the cover body is provided with a third opening, which is located on the rotation path of the covering portion of the second cover member and is used to allow at least a portion of the covering portion of the second cover member to pass through the cover body.

[0014] In some embodiments, along the length of the aerosol generating device, the top of the cover includes an upper surface and a lower surface facing away from each other, the lower surface being closer to the interior of the receiving cavity than the upper surface, the lower surface having a first extension that surrounds at least a portion of the control body; the first extension having a locking portion that extends from the first extension toward the center of the through hole, the control body having a slot, the locking portion engaging with the slot to support the control body.

[0015] In the aerosol generating apparatus of this application, the control unit drives the first and second cover members to rotate, thereby opening and closing the through-hole and the channel. When the two cover members jointly control the opening and closing of the through-hole and the channel, the required rotation angle of each cover member is reduced, thereby reducing the unilateral rotation space that the aerosol generating apparatus needs to reserve for the cover members in the second state. Therefore, the cover assembly is more compact in spatial layout, better adapting to the miniaturization design requirements of the aerosol generating apparatus.

[0031] The aerosol generating device 1000 is a structure capable of generating aerosols by applying heat to an aerosol generating medium through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, or mechanical vibration. The aerosol generating medium is a processed plant flower, stem, or leaf product that can produce aerosols after being heated. The aerosol generating medium can be in a fully solid, semi-solid, or liquid state.

[0032] When the aerosol generating medium is entirely solid, it can be prepared using processes such as rolling, slurry preparation, die casting, and extrusion. The aerosol generating medium can have a cylindrical structure similar to a cigarette, or it can be a sheet-like, strip-like, or block-like structure.

[0033] When the aerosol generating medium is non-solid (including but not limited to liquid, gel, paste, etc.), the aerosol generating medium can be loaded by a solid carrier, which can be in the form of sheets, strips, tubes or capsules.

[0034] Aerosol-generating media are heated to form aerosols. Aerosols can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which are typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. Users can inhale aerosols 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, health care, and recreation.

[0035] Please see Figures 1 to 4 The aerosol generating device 1000 includes a heating component 100 and a battery component 200. The battery component 200 is electrically connected to the heating component 100. Specifically, the battery component 200 is housed inside the housing 10 and electrically connected to the heating component 100, providing power to electronic components such as the heating element 80 in the heating component 100 to ensure that the heating component 100 can operate normally.

[0036] The heating assembly 100 includes a housing 10, a support 30, a cover 50, and a covering assembly 70. The housing 10 has an internal receiving cavity 11. The support 30 is disposed within the receiving cavity 11 and has a channel 31. The cover 50 is located at one end opening of the housing 10 and is connected to the support 30 and / or the housing 10. The covering assembly 70 includes a control member 71, a first covering member 73, and a second covering member 75. The control member 71 is rotatably connected to the cover 50 and has a through hole 7111 communicating with the outside. Along the length X direction of the heating assembly 100, the first covering member 73 and the second covering member 75 are rotatably disposed between the support 30 and the cover 50, and are rotatably engaged with the control member 71. The control member 71 is configured to rotate, thereby rotating the first covering member 73 and the second covering member 75, so that the covering assembly 70 switches between a first state and a second state. When the covering assembly 70 is in the first state, at least a portion of the first covering member 73 and at least a portion of the second covering member 75 are located on the path connecting the through hole 7111 and the channel 31, thus cutting off the connection between the through hole 7111 and the channel 31; when the covering assembly 70 is in the second state, at least a portion of the first covering member 73 and at least a portion of the second covering member 75 are located outside the path connecting the through hole 7111 and the channel 31, thus connecting the through hole 7111 and the channel 31 and forming a loading cavity 90 for loading the aerosol generating medium 3000.

[0037] Specifically, the housing 10 is a structure used to install other components and house them within the housing 10. The housing 10 of this application has a receiving cavity 11, and at least partially houses components such as the bracket 30 and the cover assembly 70 within the housing 10, thus protecting the cover assembly 70. The cross-sectional shape of the housing 10 can be, but is not limited to, circular, elliptical, rectangular, or other polygonal shapes; the cross-sectional shape of the housing 10 in this application is racetrack-shaped. The cross-section refers to the cross-section obtained by a plane perpendicular to the length direction X of the heating assembly 100. The material of the housing 10 can be plastic or metal. When the housing 10 is made of plastic, it has good insulation performance, low cost, and light weight. When the housing 10 is made of metal, it has high strength, good wear resistance, and a long service life.

[0038] In some embodiments, the support 30 is located within the receiving cavity 11 and serves to support other components within the receiving cavity 11. The support 30 has a channel 31 extending along its length direction X. An aerosol generating medium 3000 can be inserted into the channel 31 and generate an aerosol through components such as heating elements surrounding the channel 31. The shape and size of the support 30 are not limited, as long as it can be accommodated within the receiving cavity 11 and ensures stable installation of the support 30 inside the housing 10. The material of the support 30 can be metal or plastic, with metal supports 30 exhibiting higher strength and wear resistance, while plastic supports 30 offer better insulation and lower cost. On a projection plane perpendicular to the length direction X of the heating assembly 100, the channel 31 can be located at the center of the projection plane of the heating assembly 100 or offset from it. In this application, the channel 31 is located at the center of the projection plane of the heating assembly 100, ensuring a compact structure for the heating assembly 100.

[0039] Along the length X of the heating assembly 100, one end of the housing 10 has an opening, which can be used to load other components into the receiving cavity 11 so that the other components can enter the receiving cavity 11. A cover 50 is provided at the opening and is used to close at least part of the opening. It is understood that the cover 50 has a through hole 511 that communicates with the channel 31 to ensure that the aerosol generating medium 3000 can be inserted into the channel 31. The cover 50 can be connected to the bracket 30, the housing 10, or both; this application is not limited to this. Exemplarily, the cover 50 and the bracket 30 are engaged in a snap-fit ​​connection in this application.

[0040] The control element 71 controls the connection between the through hole 7111 and the channel 31. The through hole 7111 and the channel 31 are opposite and connected in the longitudinal direction X, and together form the loading cavity 90. The loading cavity 90 is used to contain the aerosol generating medium 3000. The aerosol generating medium 3000 can be inserted into the loading cavity 90. When the user suctions the aerosol generating device 1000, the aerosol generating medium 3000 can generate aerosol. Under force, the control element 71 can rotate around the cover 50, and the plane of rotation is perpendicular to the longitudinal direction X of the heating assembly 100. The control element 71 has a through hole 7111, which communicates with the outside. In one connection method, the control element 71 is partially located within the accommodating cavity 11 and partially passes through the perforation 511 of the cover 50, with the through-hole 7111 directly communicating with the outside. In another connection method, the control element 71 is entirely located within the accommodating cavity 11, with the through-hole 7111 communicating with the perforation 511, and the through-hole 7111 indirectly communicating with the outside through the perforation 511. It can be understood that the center of the through-hole 7111 and the center of the perforation 511 are located on the axis M of the channel 31, thereby ensuring the smooth entry of the aerosol generating medium 3000 into the loading cavity 90. That is, the control element 71 rotates around the axis M of the loading cavity 90.

[0041] The first cover 73 and the second cover 75 are mounted on the bracket 30 and rotatably connected to the control member 71. The control member 71 can rotate, thereby causing the first cover 73 and the second cover 75 to rotate. The first cover 73 and the second cover 75 each have their own axis of rotation. When the control member 71 rotates about axis M, the first cover 73 and the second cover 75 can rotate about their own axes of rotation, thereby changing the relative positional relationship between the first cover 73 and the second cover 75 and the loading cavity 90. For example, the axis of rotation of the first cover 73 and the second cover 75 is the axis of their rotation shaft 701. In the first state, the first cover 73 and the second cover 75 are at least partially located within the loading cavity 90, situated between the through hole 7111 and the channel 31. On a projection plane perpendicular to the length direction X, the projection of the channel 31 lies within the projection plane jointly formed by the first cover 73 and the second cover 75. Thus, the first cover 73 and the second cover 75 isolate the connection between the through hole 7111 and the channel 31, therefore, the channel 31 is not connected to the outside. The first cover 73 and the second cover 75 can prevent dust and other dirt from entering the channel 31, maintaining the cleanliness of the channel 31. In the second state, on the projection plane perpendicular to the length direction X, the projections of the first cover 73 and the second cover 75 do not coincide with the projection of the channel 31, the channel 31 is connected to the through hole 7111, thus connecting to the outside, and the aerosol generating medium 3000 can be inserted into the loading cavity 90.

[0042] The heating assembly 100 of this application uses a control element 71 to drive the first cover 73 and the second cover 75 to rotate, thereby opening and closing the through hole 7111 and the channel 31. When the two cover elements jointly control the opening and closing of the through hole 7111 and the channel 31, the required rotation angle of each cover element is reduced, thus reducing the unilateral rotation space that the heating assembly 100 needs to reserve for the cover elements in the second state. Therefore, the cover assembly 70 is more compact in spatial layout and better meets the design requirements of miniaturization of the heating assembly 100.

[0043] Please see Figure 3 and Figure 4 In some embodiments, when switching from the first state to the second state, the first cover 73 and the second cover 75 rotate synchronously and move away from each other. In some embodiments, when switching from the second state to the first state, the first cover 73 and the second cover 75 rotate synchronously and move closer to each other.

[0044] Specifically, when switching from the first state to the second state (i.e., from non-conductive to conductive), the control element 71 rotates around axis M after being subjected to force. The control element 71 drives the first covering element 73 and the second covering element 75 to rotate synchronously. The first covering element 73 and the second covering element 75 rotate around their own axes of rotation, moving away from each other. The axis of rotation of the first covering element 73 is N1, and the axis of rotation of the second covering element 75 is N2. Synchronization means that the first covering element 73 and the second covering element 75 move at the same time in a predetermined direction and speed to ensure coordinated movement. Moving away from each other means that the first covering element 73 and the second covering element 75 move away from axis M respectively. The reference point is the center line of the initial positions of the two covering elements. Synchronous movement allows each cover piece to open the channel 31 with only a small rotation angle. On the one hand, it reduces the rotation space required for each cover piece on one side within the accommodating cavity 11. On the other hand, the simultaneous movement of the first cover piece 73 and the second cover piece 75 also improves the rotation efficiency, and the efficiency of switching from the first state to the second state becomes higher.

[0045] When switching from the second state to the first state, i.e., from conductive to non-conductive, the control element 71 rotates around the axis M after being subjected to force. It can be understood that the force on the control element 71 in this case is opposite to the force when switching from the first state to the second state, and the direction of rotation of the control element 71 around the axis M is also opposite. The control element 71 drives the first cover element 73 and the second cover element 75 to rotate synchronously. The first cover element 73 and the second cover element 75 rotate around their own rotation axes and move closer to each other. The definition of synchronous is the same as above and will not be repeated here. Moving closer to each other means that the first cover element 73 and the second cover element 75 move towards the axis M respectively. At least a portion of the first cover element 73 and the second cover element 75 gradually moves to the path connecting the through hole 7111 and the channel 31, thereby cutting off the conduction between the through hole 7111 and the channel 31, thus preventing dust and other impurities from entering the heating assembly 100 and protecting the cleanliness of the internal environment. Synchronous rotation can improve the rotation efficiency of the first cover 73 and the second cover 75, and the efficiency of switching from the second state to the first state becomes higher.

[0046] Please see Figure 2 In some embodiments, the control member 71 includes a control body 711 and a mating part 713, the mating part 713 being connected to the control body 711, a through hole 7111 being provided in the control body 711, and the control body 711 being rotatably connected to the cover 50. At least one of the first cover member 73 and the second cover member 75 includes a connecting body 703 and a mating part 705, the mating part 705 being connected to the connecting body 703, the connecting body 703 being connected to the bracket 30, and the mating part 713 and the mating part 705 being rotatably engaged.

[0047] Specifically, the mating part 713 and the control body 711. In some embodiments, the mating part 713 and the control body 711 are an integral structure, that is, the mating part 713 and the control body 711 are a single unit, thereby improving the bonding strength between the mating part 713 and the control body 711 and preventing separation of the mating part 713 and the control body 711 during operation, thus ensuring the stability and reliability of the operation of the control member 71. In other embodiments, the mating part 713 and the control body 711 are separate structures, that is, the mating part 713 and the control body 711 are two different structures. Exemplarily, the mating part 713 and the control body 711 of this application are integrally formed, thereby improving the structural strength of the control member 71. The connecting body 703 and the mating part 705 can also be an integral or separate structure, which will not be elaborated here. In this application, the connecting body 703 and the mating part 705 are also integrally formed, thereby improving the structural strength of the cover (first cover 73 and / or second cover 75).

[0048] The rotatable engagement of the mating part 713 and the fitting part 705 transmits the torque of the control member 71 to the first cover member 73 and the second cover member 75, causing the first cover member 73 and the second cover member 75 to rotate under the drive of the control member 71, thereby realizing the opening and closing of the through hole 7111 and the channel 31. Exemplarily, the mating part 713 and the fitting part 705 in this application are gears, and the mating part 713 and the fitting part 705 mesh with each other. In this application, the first cover member 73 and the second cover member 75 have identical structures, which is more conducive to processing and forming.

[0049] Please see Figure 2 In some embodiments, the cover 50 includes a top 51 and a side portion 53 surrounding the top 51. The side portion 53 has a first opening 531, and the housing 10 has a through hole 13 corresponding to the first opening 531. The control member 71 also includes a toggle part 715, which is connected to the side wall of the control body 711 and extends out of the housing 10 after passing at least partially through the first opening 531 and the through hole 13. The toggle part 715 is configured to move in the first opening 531 after being subjected to force, thereby driving the control member 71 to rotate.

[0050] Specifically, the top 51 of the cover 50 is used to close one end opening of the housing 10, and the side portion 53 surrounds the periphery of the top 51. The first opening 531 of the side portion 53 provides a channel 31 for the actuating part 715 of the control member 71, allowing the actuating part 715 to pass through the first opening 531 and align with the through hole 13 on the housing 10. The through hole 13 on the housing 10 is positioned opposite to the first opening 531, ensuring that the actuating part 715 can extend outside the housing 10 for easy user operation. The shapes of the through hole 13 and the first opening 531 include, but are not limited to, perfect circles, ellipses, or polygons.

[0051] The actuating portion 715 of the control element 71 is connected to the side wall of the control body 711. Exemplarily, the side wall of the control body 711 has an opening, at least a portion of the actuating portion 715 extends into the opening and forms an interference fit with the side wall of the control body 711, or is connected by adhesive. A portion of the actuating portion 715 can pass through the first opening 531 and the through hole 13. When the user applies external force to the actuating portion 715, the actuating portion 715 moves in the first opening 531, thereby causing the control element 71 to rotate around the cover 50. Since the control element 71 is rotatably connected to the first cover 73 and the second cover 75, the rotation of the control element 71 causes the cover to rotate synchronously, realizing the connection and disconnection between the through hole 7111 and the channel 31.

[0052] Please see Figures 2 to 5In some embodiments, when the toggle part 715 is in a first position of the first opening 531, the cover assembly 70 is in a first state. When the toggle part 715 is in a second position of the first opening 531, the cover assembly 70 is in a second state.

[0053] Specifically, the position of the actuating part 715 in the first opening 531 corresponds to the state of the covering assembly 70. When the actuating part 715 is in the first position of the first opening 531, the covering assembly 70 is in the first state. At this time, at least a portion of the first covering member 73 and the second covering member 75 are located on the path connecting the through hole 7111 and the channel 31, cutting off the connection between the through hole 7111 and the channel 31 and preventing dust from entering the interior of the heating assembly 100. For example, when the actuating part 715 is in the first position, its relative position to the first opening 531 causes the control member 71 to remain in the corresponding position, thereby driving the first covering member 73 and the second covering member 75 to be in the state of closing the through hole 7111 and the channel 31. When the actuating part 715 is in the second position of the first opening 531, the covering assembly 70 is in the second state. At this time, at least a portion of the first cover 73 and the second cover 75 are located outside the path connecting the through hole 7111 and the channel 31, thus connecting the through hole 7111 and the channel 31 and forming a loading cavity 90, facilitating the loading and use of the aerosol generating medium 3000. The heating assembly 100 corresponds to different states of the cover assembly 70 by adjusting the position of the toggle part 715 in the first opening 531, allowing the user to intuitively understand the current state of the cover assembly 70. The user can easily switch the state of the cover assembly 70 by simply moving the toggle part 715, making the operation simple and easy to control.

[0054] Please see Figure 2 , Figure 5 and Figure 6 In some embodiments, the heating assembly 100 further includes a heating element 80, and the support 30 includes a first support 33, a second support 35 disposed on the first support 33, and a third support 37 located below the second support 35. The cover 50 can be connected to the first support 33, and the heating element 80 is connected to both the second support 35 and the third support 37. A channel 31 is provided between the second support 35, the heating element 80, and the third support 37. The second support 35 and / or the cover 50 are provided with a mounting portion, and at least one of the first cover 73 and the second cover 75 further includes a rotating shaft 701 and a covering portion 707. The rotating shaft 701 is connected to the connecting body 703 and is rotatably connected to the mounting portion. The covering part 707 is connected to the connecting body 703. When the covering assembly 70 is in the first state, at least a portion of the covering part 707 is located on the path connecting the through hole 7111 and the channel 31. When the covering assembly 70 is in the second state, at least a portion of the covering part 707 is located outside the path connecting the through hole 7111 and the channel 31.

[0055] Specifically, the heating element 80 is a component capable of generating heat energy and transferring it to the surrounding environment. In some embodiments, the heating element 80 may include porous ceramic, a heating layer, and a conductive element. When the conductive element transfers electrical energy to the heating layer, the heating layer can generate heat and heat the aerosol generating medium 3000 of the aerosol generating product 3000 through the porous ceramic. It should be noted that in some embodiments, the porous ceramic is typically prepared by mixing a ceramic slurry with a pore-forming agent and then sintering it, resulting in a large number of micropores (not shown in the figure) within the sintered ceramic body. The heating layer includes, but is not limited to, at least one of heating circuits, heating plates, heating wires, and heating meshes. The conductive element may be integrated with the battery assembly 200 (…). Figure 1 (As shown) an electrical connection, thereby enabling the conductive element to transfer electrical energy from the battery assembly 200 to the heating layer, causing the heating layer to heat up. It should be noted that in some embodiments, the electrodes may include, but are not limited to, sheet-like, columnar, or porous powder forms.

[0056] The cover 50 is connected to the first support 33, for example, by a threaded connection, a snap-fit ​​connection, or other connection methods. Exemplarily, the side 53 of the cover 50 has a second extension 535, which protrudes towards the first support 33 along the length X direction of the heating assembly 100. The first support 33 has a first connecting portion 331, and the second extension 535 has a second connecting portion 5351, which are engaged. Exemplarily, the first connecting portion 331 and the second connecting portion 5351 are engaged, with the first connecting portion 331 being a slot 7113 and the second connecting portion 5351 being a locking element. A channel 31 is provided in the second support 35, the heating element 80, and the third support 37, extending from the upper part of the second support 35 to the lower part of the third support 37, penetrating the heating element 80 to form a continuous channel 31, which facilitates the smooth flow of the aerosol generating medium 3000.

[0057] The second bracket 35 and / or the cover 50 are provided with mounting portions, which can be protrusions, grooves, or other suitable structures for rotatable connection with the pivot 701 of the cover. Exemplarily, both the second bracket 35 and the cover 50 of this application are provided with mounting portions. The second bracket 35 has a first mounting portion 351, and the cover 50 has a second mounting portion 517.

[0058] The first mounting portion 351 and the second mounting portion 517 are opposite each other in the longitudinal direction X. At least one of the first cover member 73 and the second cover member 75 further includes a pivot 701 and a cover portion 707. As mentioned above, the first cover member 73 and the second cover member 75 of this application have the same structure, that is, both the first cover member 73 and the second cover member 75 include a pivot 701 and a cover portion 707. The pivot 701 is connected to the connecting body 703 and protrudes from both sides of the connecting body 703 in the longitudinal direction X, thereby inserting into the mounting portion of the second bracket 35 and the mounting portion of the cover 50. The pivot 701 can rotate within the mounting portion to drive the cover member to rotate around the pivot 701. The cover portion 707 is connected to the connecting body 703. In the first state, at least a portion of the cover portion 707 is located on the path connecting the through hole 7111 and the channel 31, cutting off the connection between the through hole 7111 and the channel 31 to prevent dust from entering the receiving cavity 11 inside the heating assembly 100. In the second state, at least a portion of the cover portion 707 is located outside the path connecting the through hole 7111 and the channel 31, opening the through hole 7111 and the channel 31 to form a loading cavity 90, facilitating the loading and use of the aerosol generating medium 3000.

[0059] Please see Figure 2 and Figure 4 In some embodiments, the second bracket 35 is provided with a limiting protrusion 355, which is located on the rotation path of the covering part 707 and is used to limit the rotation angle of the covering part 707.

[0060] Specifically, there can be one or more limiting protrusions 355. In this application, there are two limiting protrusions 355, which are located on the rotation path of the covering portion 707 of the first covering member 73 and the rotation path of the covering portion 707 of the second covering member 75, respectively. They are used to limit the rotation angle of the covering portion 707 of the first covering member 73 and the second covering member 75, so that the covering portion 707 can be limited to a predetermined angle range during rotation. When the cover assembly 70 is in the first state or the second state, the limiting protrusion 355 can prevent the cover part 707 from rotating excessively, avoid the toggle part 715 from hitting the side wall of the first opening 531, and also prevent the cover parts 707 of the first cover member 73 and the second cover member 75 from hitting the side part 53 of the cover body 50, ensuring that at least a portion of the cover parts 707 of the first cover member 73 and the second cover member 75 are always located on or outside the path connecting the through hole 7111 and the channel 31, thereby achieving a stable conduction or shutdown effect.

[0061] Furthermore, the second bracket 35 is also provided with a first reinforcing part 353, and the cover 50 is provided with a second reinforcing part 519 corresponding to the first reinforcing part 353 and the limiting protrusion 355. The number of these second reinforcing parts is not limited in this application. For example, the second bracket 35 has two limiting protrusions 355 and two first reinforcing parts 353, and the cover 50 has four second reinforcing parts 519. The second reinforcing parts 519 are disposed opposite to and fit against the first reinforcing parts 353 and the limiting protrusions 355 in the length direction X, which can enhance the connection strength between the cover 50 and the second bracket 35.

[0062] Please see Figure 2 and Figure 4 In some embodiments, the cover 50 is provided with a second opening 532, which is located on the rotation path of the covering portion 707 of the first covering member 73 and is used to allow at least part of the covering portion 707 of the first covering member 73 to pass through to the outside of the cover 50.

[0063] Specifically, the second opening 532 expands the rotation angle of the covering portion 707 of the first covering member 73. During rotation, the covering portion 707 of the first covering member 73 can partially pass through the second opening 532, preventing direct collision between it and the cover body 50, thus avoiding potential damage or deformation caused by impacts. This not only improves the service life of the covering portion 707 of the first covering member 73 but also ensures its stability and reliability during rotation, thereby guaranteeing that the covering assembly 70 can accurately switch between the first and second states, achieving effective control over the connection and disconnection of the through hole 7111 and the channel 31.

[0064] Please see Figure 2 and Figure 4 In some embodiments, the cover 50 is provided with a third opening 533, which is located on the rotation path of the covering portion 707 of the second covering member 75 and is used to allow at least part of the covering portion 707 of the second covering member 75 to pass through to the outside of the cover 50.

[0065] Specifically, the third opening 533 expands the rotation angle of the covering portion 707 of the second cover 75. During rotation, the covering portion 707 of the second cover 75 can partially pass through the third opening 533, preventing direct collision between it and the cover 50 and avoiding potential damage or deformation. This not only improves the service life of the covering portion 707 of the second cover 75 but also ensures its stability and reliability during rotation, thereby guaranteeing that the cover assembly 70 can accurately switch between the first and second states, achieving effective control over the connection and disconnection of the through hole 7111 and the channel 31.

[0066] Please see Figure 2 and Figure 6 In some embodiments, along the length direction X of the heating assembly 100, the top 51 of the cover 50 includes an upper surface 512 and a lower surface 513 facing away from each other. The lower surface 513 is closer to the interior of the receiving cavity 11 than the upper surface 512. The lower surface 513 is provided with a first extension 515, which surrounds at least part of the control body 711. The first extension 515 is provided with a locking portion 5151, which extends from the first extension 515 toward the center of the through hole 7111. The control body 711 is provided with a slot 7113, and the locking portion 5151 cooperates with the slot 7113 to support the control body 711.

[0067] Specifically, the first extension 515 surrounds at least a portion of the control body 711, thereby supporting and limiting the control body 711, ensuring that the control body 711 remains within a predetermined range during rotation and does not deviate from the center of rotation. There can be one or more first extensions 515; this application has five first extensions 515, arranged around the through hole 511. At least a portion of the first extension 515 is provided with a locking portion 5151, extending from the first extension 515 towards the center of the through hole 7111, cooperating with a slot 7113 on the control body 711 to support the control body 711. Exemplarily, this application has three locking portions 5151. Therefore, the cover 50 bears the weight and part of the force of the control body 711, reducing the pressure on the second bracket 35. Simultaneously, the first extension 515 also has a dustproof function, effectively preventing dust, moisture, and other impurities from entering the accommodating cavity 11 and affecting the normal operation of the heating assembly 100. In addition, the first extension 515 also serves to conceal imperfections to some extent, preventing users from directly seeing the complex internal structure and improving the product's appearance.
