Aerosol generation device

[0001] Priority information

[0002] This application claims priority and benefits to patent application No. 202423030099.8, filed with the China National Intellectual Property Administration on December 6, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of aerosol generation apparatus 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 matrix using a non-combustible method. Aerosol generating devices typically have a loading port to accommodate the aerosol generating matrix 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 moves within the aerosol generating device to close or open the loading port. However, when the aerosol generating device is small, the space for the dust cover to move is very limited. Therefore, improving the space utilization of the dust cover structure within the aerosol generating device has become a technical problem to be solved. Summary of the Invention

[0005] This application provides an aerosol generating apparatus.

[0006] The aerosol generating apparatus according to the present application includes a housing and a rolling mechanism. The housing has a loading hole for receiving an aerosol generating matrix inserted into the housing. The rolling mechanism is rotatably disposed inside the housing and includes a ball body with a hollow portion extending through it. The ball body is configured to rotate relative to the housing in a first direction with the rolling mechanism to close the loading hole, and the hollow portion is configured to rotate relative to the housing in a second direction with the ball body to communicate with the loading hole. The first and second directions are opposite directions.

[0007] The aerosol generating device of this application adopts a ball-shaped rolling mechanism instead of a plate-shaped dust cover structure. The ball body rotates in a first direction to a certain angle to close the loading hole, and rotates in a second direction to another angle to make the hollow part communicate with the loading hole and open the loading hole. This makes the moving space of the ball body close to the volume space of the ball body, thereby improving the space utilization rate and facilitating the miniaturization of the aerosol generating device.

[0008] In some embodiments, the rolling mechanism includes a rotating shaft, a ball body fixedly connected to the rotating shaft, a rotating shaft rotatably connected to the housing, and an extension line of the rotating shaft passing through the hollow portion and forming an angle with the direction in which the hollow portion penetrates the ball body.

[0009] In this way, the ball bearing body rotates relative to the housing by the rotating shaft. The extension line of the rotating shaft passes through the hollow part and forms an angle with the direction in which the hollow part passes through the ball bearing body, so that the ball bearing body rotates around the rotating shaft relative to the housing, reducing the space occupied by the rolling mechanism.

[0010] In some embodiments, the rolling mechanism includes a first magnetic element disposed on the ball body, and a second magnetic element with opposite magnetism to the first magnetic element disposed on the housing. The second magnetic element is used to attract the first magnetic element as the rolling mechanism rotates in a first direction.

[0011] Thus, the second magnetic element attracts the first magnetic element as the rolling mechanism rotates in the first direction, thereby driving or assisting the ball body to rotate to close the loading hole.

[0012] In some embodiments, the distance between the first magnetic element and the second magnetic element is minimum when the ball body closes the loading hole and maximum when the hollow part is connected to the loading hole.

[0013] Thus, as the first magnetic component rotates along the first direction with the rolling mechanism, it gradually approaches the second magnetic component, causing the attraction between the first and second magnetic components to gradually increase as the rolling mechanism rotates along the first direction. This assists the rolling mechanism in rotating and creates a large magnetic attraction force when the ball body closes the loading hole, maintaining structural stability.

[0014] In some embodiments, a third magnetic element with the opposite magnetic properties to the first magnetic element is provided on the housing. The third magnetic element and the second magnetic element are spaced apart. A rolling mechanism is located between the third magnetic element and the second magnetic element. The third magnetic element is used to attract the first magnetic element so that the rolling mechanism remains stationary relative to the housing when the hollow part is in communication with the loading hole.

[0015] Thus, the magnetic attraction between the first and second magnetic components keeps the rolling mechanism stationary relative to the housing while the hollow part is connected to the loading hole, thereby keeping the loading hole open and facilitating the insertion of the aerosol generation matrix.

[0016] In some embodiments, the distance between the first magnetic element and the third magnetic element is greatest when the ball body closes the loading hole, and smallest when the hollow part is connected to the loading hole.

[0017] Thus, as the rolling mechanism rotates along the second direction, the first and third magnetic components gradually approach each other, causing the attraction between them to gradually increase. This assists the rolling mechanism in rotating to open the loading hole, and a large magnetic attraction is formed when the hollow part is connected to the loading hole, maintaining structural stability.

[0018] In some embodiments, the rolling mechanism includes a first limiting part and a second limiting part. The housing is provided with a limiting structure. The limiting structure cooperates with the first limiting part when the ball body closes the loading hole, and cooperates with the second limiting part when the hollow part communicates with the loading hole, so as to limit the position of the rolling mechanism.

[0019] Thus, by using the limiting structure to cooperate with the first limiting part when the ball body is in the closed loading hole state, and to cooperate with the second limiting part when the hollow part is in communication with the loading hole, the rotation range of the rolling mechanism along the first and second directions is limited, which is beneficial for the rolling mechanism to remain stationary relative to the housing when the loading hole is closed and open.

[0020] In some embodiments, the limiting structure includes limiting ribs, with a first limiting portion and a second limiting portion spaced apart and protruding from the surface of the ball body. The limiting ribs abut against the first limiting portion when the ball body closes the loading hole, and abut against the second limiting portion when the hollow portion is in communication with the loading hole.

[0021] Thus, with the first and second limiting parts distributed at intervals and protruding from the surface of the ball body, the limiting ribs abut against the first limiting part when the ball body is in the state of closing the loading hole, and abut against the second limiting part when the hollow part is in the state of communicating with the loading hole, thereby effectively limiting the rotation angle range of the rolling mechanism, which is beneficial to maintaining the structural stability when the loading hole is open or closed.

[0022] In some embodiments, the housing is formed with a relief groove on one side of the ball body, and a limiting rib is formed on the groove wall of the relief groove. The relief groove is used to provide the movement space of the first limiting part and the second limiting part.

[0023] In this way, the clearance groove provides space for the first and second limiting parts to move, and the limiting ribs are formed on the groove wall of the clearance groove, thereby improving space utilization, avoiding structural interference, and ensuring that the rolling mechanism moves within the preset range.

[0024] In some embodiments, the ball body includes a cover portion and a movable portion, which together form a hollow portion. At least a portion of the surface of the cover portion facing away from the hollow portion forms a first arc surface, which is at least partially exposed outside the loading hole when the ball body is in the state of closing the loading hole.

[0025] Thus, by having the first arc surface extend at least partially outside the loading hole when the ball body is closed, the ball body can utilize the space outside the loading hole as its own movement space, thereby saving space inside the aerosol generating device. Furthermore, the exposed first arc surface also indicates the closed status of the loading hole, facilitating user operation.

[0026] In some embodiments, the rolling mechanism includes a rotating shaft rotatably connected to the housing, the extension of which passes through the center of the first arc surface.

[0027] In this way, by having the extension line of the rotating shaft pass through the center of the first arc surface, the first arc surface remains within the same sphere as the ball body rotates, thereby restricting the activity space of the covering part to the sphere where the first arc surface is located, improving the space utilization rate inside the aerosol generating device, and helping other components to avoid the activity space of the covering part, reducing structural interference.

[0028] In some embodiments, the side of the movable part opposite to the first arc surface forms a second arc surface, and the centers of the first and second arc surfaces coincide.

[0029] In this way, the centers of the first and second arc surfaces coincide, ensuring that the first and second arc surfaces remain within the same sphere during the rotation of the ball body. This limits the space occupied by the ball body, improves space utilization, facilitates the design and arrangement of other components inside the aerosol generating device, and helps reduce structural interference.

[0030] In some embodiments, the housing includes a top cover, an outer shell, and a support, with the top cover and outer shell together forming the internal space of the housing. The top cover forms a loading hole, and the support is mounted in the internal space of the housing. A rolling mechanism is rotatably connected to the support.

[0031] Thus, by mounting the support in the internal space of the housing, the rolling mechanism is rotatably connected to the support, allowing the rolling mechanism to be mounted at a certain height in the internal space. This facilitates the rolling mechanism to be positioned close to the loading hole and to roll within a limited space to open or close the loading hole.

[0059] Please refer to Figures 1 and 2. The aerosol generating device 100 is a structure capable of generating aerosols by acting on an aerosol generating matrix (not shown) through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, or mechanical vibration. The aerosol generating matrix is ​​a plant leaf product that has been treated and heated to produce aerosols. The aerosol generating matrix can be in a fully solid or semi-solid state. When the aerosol generating matrix is ​​fully solid, it can be prepared using processes such as rolling, slurry preparation, die casting, or extrusion. The aerosol generating matrix can be a cylindrical structure similar to a cigarette, or a sheet-like, strip-like, or block-like structure.

[0060] Aerosol generating matrix is ​​atomized by heating 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, and health care.

[0061] Please refer to Figures 3-5. The aerosol generating apparatus 100 of this application embodiment includes a housing 10 and a rolling mechanism 20. The housing 10 has a loading hole 101 for receiving an aerosol generating matrix inserted into the housing 10. The rolling mechanism 20 is rotatably disposed inside the housing 10. The rolling mechanism 20 includes a ball body 21 and a hollow portion 22 formed therein. The hollow portion 22 extends through the ball body 21. The ball body 21 is configured to rotate relative to the housing 10 along a first direction w to close the loading hole 101. The hollow portion 22 is configured to rotate relative to the housing 10 along a second direction v to communicate with the loading hole 101. The first direction w and the second direction v are opposite directions.

[0062] The aerosol generating device 100 of this application adopts a ball-shaped rolling mechanism 20 instead of a plate-shaped dust cover structure. The ball body 21 rotates along the first direction w to a certain angle to close the loading hole 101, and rotates along the second direction v to another angle to make the hollow part 22 communicate with the loading hole 101 and open the loading hole 101. This makes the moving space of the ball body 21 close to the volume space of the ball body 21. Thus, even with a small size, the opening and closing of the loading hole 101 can still be effectively realized, improving the space utilization rate and facilitating the miniaturization of the aerosol generating device 100.

[0063] Specifically, the aerosol generating device 100 includes a top 11 and a bottom 12, which 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 through the top 11. When the loading hole 101 is open, the hollow portion 22 penetrates the rolling mechanism 20 in the vertical direction. The hollow portion 22 and the loading hole 101 together connect the internal space of the housing 10 and the external environment.

[0064] The housing 10 can be generally cylindrical, and components such as a battery (not shown), control components (not shown), and a heating element (not shown) can be installed inside. 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 8.

[0065] The rotation center of the rolling mechanism 20 is located inside the ball body 21, which can rotate relative to the housing 10, so that the rolling mechanism 20 is always located below the loading hole 101 during rotation. The plane containing the first direction w and the second direction v can be parallel to the vertical direction.

[0066] The aperture and shape of the loading hole 101 match the outer contour shape and size of the aerosol generating matrix, while the aperture and shape of the hollow portion 22 match the aperture and shape of the loading hole 101. For example, the aerosol generating matrix is ​​a cylindrical structure similar to a cigarette, the loading hole 101 is a circular hole, and the cross-sectional shape of the hollow portion 22 is circular. When the loading hole 101 is open, the hollow portion 22 is directly opposite to and connected to the loading hole 101.

[0067] With the loading hole 101 open, the aerosol generating matrix can pass through the loading hole 101 and the hollow part 22 and be inserted into a deeper part inside the aerosol generating device 100. The aerosol generating matrix (or the carrier of the aerosol generating matrix) abuts against the wall of the hollow part 22 formed by the ball body 21, providing a certain support for the ball body 21 to maintain the state in which the hollow part 22 is opposite and connected to the loading hole 101.

[0068] The ball bearing body 21 can be partially exposed through the loading hole 101 in both the open and closed states. The user can rotate the ball bearing body 21 by turning it. Alternatively, the user can use the force of the aerosol generating matrix to rotate the ball bearing body 21 along the second direction v, connecting the hollow portion 22 to the loading hole 101, thus opening the loading hole 101. Or, the user can use the force of the aerosol generating matrix to pull the ball bearing body 21 out, thus closing the loading hole 101.

[0069] Optionally, the aerosol generating apparatus 100 further includes a receiving tube 30, which provides a heating site for the aerosol generating matrix. The receiving tube 30 extends downward into the aerosol generating apparatus 100, with its top end forming an opening directly opposite the loading hole 101, so that the aerosol generating matrix can be inserted into the receiving tube 30 through the loading hole 101.

[0070] Please refer to Figures 4 and 5. In some embodiments, the housing 10 includes a top cover 13, an outer shell 14, and a bracket 15. The top cover 13 and the outer shell 14 together form the internal space of the housing 10. The top cover 13 forms a loading hole 101. The bracket 15 is mounted in the internal space of the housing 10. The rolling mechanism 20 is rotatably connected to the bracket 15.

[0071] Thus, the rolling mechanism 20 is rotatably connected to the bracket 15 in the internal space of the housing 10, and the rolling mechanism 20 is mounted at a certain height in the internal space. This makes it easier for the rolling mechanism 20 to be positioned close to the loading hole 101 and to roll within a limited space to open or close the loading hole 101.

[0072] Specifically, the top cover 13, the outer shell 14, and the bracket 15 are fixedly connected in pairs. The outer shell 14 forms an opening at the top 11, and the top cover 13 closes onto the opening of the outer shell 14 to enclose the internal space of the shell 10. The bracket 15 can be disposed close to the top 11 of the shell 10, with the top cover 13 and the bracket 15 facing each other vertically. The rolling mechanism 20 is installed between the top cover 13 and the bracket 15 through the bracket 15.

[0073] Optionally, when the loading hole 101 is closed, the loading hole 101 is located within the projection range of the ball body 21 in the vertical direction on the upper cover 13, so that the ball body 21 can completely block the loading hole 101.

[0074] Optionally, referring to Figures 7 and 8, the upper cover 13 includes a cover plate 131 and a flange plate 132. The cover plate 131 covers the opening of the housing 14, and the flange plate 132 extends downward from the edge of the cover plate 131 into the housing 14 and connects to the housing 14 and the bracket 15. The cover plate 131 may be a curved plate, forming a slightly outwardly convex curved surface from the edge to the center. A loading hole 101 may be formed in the middle of the cover plate 131. The ball body 21 may partially protrude from or extend from the loading hole 101. This design makes the structure compact and helps to improve space utilization.

[0075] Optionally, referring to Figures 5 and 18, the support 15 has a bowl-shaped structure and forms a receiving space, in which the rolling mechanism 20 is partially housed.

[0076] Optionally, referring to Figures 5 and 10, a through hole 151 is formed on the bracket 15, and the through hole 151 is formed below the rolling mechanism 20. With the hollow part 22 communicating with the loading hole 101, the loading hole 101, the hollow part 22, the through hole 151 and the opening at the top of the receiving tube 30 are connected sequentially in the vertical direction.

[0077] Please refer to Figures 10 and 11. In some embodiments, the rolling mechanism 20 includes a rotating shaft 23, the ball body 21 is fixedly connected to the rotating shaft 23, the rotating shaft 23 is rotatably connected to the housing 10, and the extension line of the rotating shaft 23 passes through the hollow part 22 and forms an angle with the direction of the hollow part 22 penetrating the ball body 21.

[0078] Thus, the rotating shaft 23 drives the ball body 21 to rotate relative to the housing 10. The extension line of the rotating shaft 23 passes through the hollow part 22 and forms an angle with the direction in which the hollow part 22 passes through the ball body 21, thereby causing the ball body 21 to rotate around the rotating shaft 23 relative to the housing 10, reducing the space occupied by the rolling mechanism 20.

[0079] Specifically, the rotating shaft 23 and the ball body 21 can be separate components that are assembled into a whole, or they can be integrally formed parts. One end of the rotating shaft 23 is fixedly connected to the ball body 21 by at least one of the following methods: welding, snap-fit ​​connection, fastener connection, riveting, threaded connection, etc., and the other end of the rotating shaft 23 passes through the housing 10.

[0080] As is easily understood, the rolling mechanism 20 can rotate about the shaft 23 along a first direction w and a second direction v, with the axis of the shaft 23 perpendicular to the plane containing the first direction w and the second direction v. For ease of explanation, the direction indicated by the axis of the shaft 23 is defined as the front-back direction. The extension line of the shaft 23 extends along the axis of the shaft 23, and the ball body 21 and the hollow portion 22 rotate about the shaft 23 and its extension line along the first direction w or the second direction v.

[0081] In some embodiments, the direction in which the hollow portion 22 penetrates the ball body 21 may be perpendicular to the axial direction of the rotating shaft 23. When the rolling mechanism 20 is in a state where the hollow portion 22 is connected to the loading hole 101, as shown in FIG12, the direction in which the hollow portion 22 penetrates the ball body 21 is vertical. When the ball body 21 is completely closed to the loading hole 101, the direction in which the hollow portion 22 penetrates the ball body 21 is horizontal (as shown in FIG11, the direction perpendicular to the plane of the paper).

[0082] Optionally, the ball body 21 is connected to the housing 10 on the front and rear sides of the ball body 21 via two rotating shafts 23, respectively, so that the ball mechanism can be mounted inside the housing 10 and rotate relative to the housing 10. The two rotating shafts 23 are distributed along the same straight line to keep the ball body 21 in balance.

[0083] Optionally, referring to Figures 5 and 10, a mounting plate 133 is provided on the lower side of the upper cover 13. The mounting plate 133 extends downward from the edge of the loading hole 101 and is opposite to the ball body 21. Mounting holes 1331 are formed on the two mounting plates, and the rotating shaft 23 can partially extend into the mounting holes 1331. There are two mounting plates 133, which are respectively provided on the front and rear sides of the ball body 21, and the two mounting holes 1331 are directly opposite each other in the front-rear direction. In this embodiment, the rotating shaft 23 is short cylindrical and is respectively provided on the front and rear sides of the ball body 21. The two rotating shafts 23 are respectively passed through the front and rear mounting holes 1331 and can rotate relative to the upper cover 13 in the mounting holes 1331.

[0084] Please refer to Figures 12 and 13. In some embodiments, the rolling mechanism 20 includes a first magnetic element 24 disposed on the ball body 21, and a second magnetic element 18 disposed on the housing 10 with the opposite magnetism to the first magnetic element 24. The second magnetic element 18 is used to attract the first magnetic element 24 during the rotation of the rolling mechanism 20 along the first direction w.

[0085] Thus, the second magnetic element 18 attracts the first magnetic element 24 during the rotation of the rolling mechanism 20 in the first direction w, thereby driving or assisting the ball body 21 to rotate to close the loading hole 101.

[0086] Specifically, both the first magnetic element 24 and the second magnetic element 18 are permanent magnets with opposite magnetic properties; one of them is the N pole, and the other is the S pole. The first magnetic element 24 and the second magnetic element 18 can be in the form of a block, cylinder, prism, sheet, plate, or other irregular structure; this application does not impose any restrictions on this. For ease of production, both the first magnetic element 24 and the second magnetic element 18 are in a block shape.

[0087] Optionally, referring to Figures 12 and 19, the ball body 21 has a first receiving groove 211, in which the first magnetic element 24 can be fixedly installed. The first receiving groove 211 can be formed on the second arcuate surface 2162 of the movable part 216. The first magnetic element 24 is at least partially received in the first receiving groove 211 and located within the spherical surface where the second arcuate surface 2162 is located, thereby saving installation space for the first magnetic element 24. Part of the surface of the first magnetic element 24 is exposed through the opening of the first receiving groove 211, which is beneficial for generating magnetic forces between the first magnetic element 24 and other magnets.

[0088] Optionally, referring to Figure 5, the bracket 15 is formed with a second receiving groove 182 for receiving the second magnetic element 18. The second magnetic element 18 can be fixedly mounted on the bracket 15.

[0089] In some embodiments, the first direction w is a counterclockwise direction from the upper left to the lower right, and the second direction v is a clockwise direction from the lower right to the upper left. In this embodiment, the second magnetic element 18 is disposed on the right side of the ball body 21, and the first magnetic element 24 can move relative to the second magnetic element 18 on the left side (including the upper left and lower left sides) of the ball body 21.

[0090] Conversely, in some other embodiments, the first direction w is a clockwise direction from the upper right to the lower left, the second direction v is a counterclockwise direction from the lower left to the upper right, and the second magnetic element 18 is disposed on the left side of the ball body 21.

[0091] Taking the second magnetic element 18 located on the right side of the ball body 21 as an example, when the loading hole 101 is open, the first magnetic element 24 is located on the left side of the hollow portion 22. During the rotation of the rolling mechanism 20 along the first direction w, i.e., during the closing of the loading hole 101, the first magnetic element 24 swings downwards and to the right along the first direction w, approaching the second magnetic element 18 on the right side. The magnetic force between the first magnetic element 24 and the second magnetic element 18 promotes the swinging of the first magnetic element 24 along the first direction w. When the loading hole 101 is closed, the side of the ball body 21 opposite to the first magnetic element 24 covers the loading hole 101. The first magnetic element 24 is located on the lower side of the hollow portion 22, and the second magnetic element 18 can be located directly to the right, above the right, below the right, or below the first magnetic element 24.

[0092] Furthermore, to avoid the space where the aerosol generating matrix is ​​inserted into the housing 10, the second magnetic element 18 is located on the lower right side of the ball body 21. When the loading hole 101 is closed, the first magnetic element 24 is located on the lower side of the hollow part 22, and the second magnetic element 18 is located on the right side of the first magnetic element 24 and is slightly higher than the first magnetic element 24 in the vertical direction.

[0093] With the loading hole 101 open, the ball body 21 is supported by the aerosol generating matrix (or its carrier) and maintains communication between the hollow portion 22 and the loading hole 101. After the aerosol generating matrix is ​​removed, the magnetic force between the first magnetic element 24 and the second magnetic element causes the ball body 21 to rotate along the first direction w, and the hollow portion 22 is displaced from the loading hole 101 until the ball body 21 completely closes the loading hole 101, thereby achieving the effect that the ball body 21 automatically closes the loading hole 101 as the aerosol generating matrix is ​​removed.

[0094] Please continue to refer to Figures 12 and 13. In some embodiments, the distance between the first magnetic element 24 and the second magnetic element 18 is the smallest when the ball body 21 closes the loading hole 101, and the largest when the hollow part 22 is connected to the loading hole 101.

[0095] Thus, as the first magnetic element 24 rotates along the first direction w with the rolling mechanism 20, it gradually approaches the second magnetic element 18, causing the attraction between the first magnetic element 24 and the second magnetic element 18 to gradually increase as the rolling mechanism 20 rotates along the first direction w, thereby assisting the rolling mechanism 20 to rotate, and forming a large magnetic attraction force when the ball body 21 closes the loading hole 101, thus maintaining structural stability.

[0096] Specifically, referring to Figure 5, the rotating shaft 23 is arranged along the front-to-back direction, and the first magnetic element 24 is arranged on the left or right side of the ball body 21. The first magnetic element 24 oscillates relative to the housing 10 around the extension line of the rotating shaft 23 during the rotation of the rolling mechanism 20 relative to the housing 10. For ease of explanation, the first magnetic element 24 is defined as oscillating relative to the housing 10 along a first direction w from the starting point to the ending point.

[0097] The second magnetic element 18 may be disposed below the ball body 21, near the end point of the swing of the first magnetic element 24. The second magnetic element 18 may also be located on or near the extension line of the swing path of the first magnetic element 24 along the first direction w.

[0098] As the first magnetic element 24 rotates along the first direction w with the ball body 21 to close the loading hole 101, the distance between the first magnetic element 24 and the second magnetic element 18 gradually shortens. During this process, the magnetic force attracting the first magnetic element 24 and the second magnetic element 18 tends to increase. The distance between the first magnetic element 24 and the second magnetic element 18 is minimal when the loading hole 101 is closed. Therefore, the magnetic attraction between the first magnetic element 24 and the second magnetic element 18 is maximum when the loading hole 101 is closed, making it less likely for the ball body 21 to loosen when the loading hole 101 is closed.

[0099] With the loading hole 101 closed, the ball body 21 is partially exposed through the loading hole 101. The user can move the ball body 21 to overcome the magnetic attraction between the first magnetic element 24 and the second magnetic element 18 and rotate it in the second direction v, thereby opening the loading hole 101.

[0100] Please refer to Figures 14-17. In some embodiments, the housing 10 is provided with a third magnetic element 19 whose magnetism is opposite to that of the first magnetic element 24. The third magnetic element 19 and the second magnetic element 18 are spaced apart. The rolling mechanism 20 is located between the third magnetic element 19 and the second magnetic element 18. The third magnetic element 19 is used to attract the first magnetic element 24 so that the rolling mechanism 20 remains stationary relative to the housing 10 when the hollow part 22 is in communication with the loading hole 101.

[0101] Thus, the magnetic attraction between the first magnetic element 24 and the third magnetic element 19 keeps the rolling mechanism 20 stationary relative to the housing 10 while the hollow part 22 is connected to the loading hole 101, thereby keeping the loading hole 101 open and facilitating the insertion of the aerosol generation matrix.

[0102] Specifically, the third magnetic element 19 is a permanent magnet, and one of the third magnetic element 19 and the first magnetic element 24 is the N pole and the other is the S pole. The third magnetic element 19 has the same magnetism as the second magnetic element 18. The third magnetic element 19 can be in the form of a cube, cylinder, prism, sheet, plate or other irregular structure, and this application does not limit it in this way.

[0103] To increase the magnetic attraction between the third magnetic component 19 and the first magnetic component 24 when the loading hole 101 is open, the third magnetic component 19 is positioned on the housing 10 close to the starting point of the first magnetic component 24's swing relative to the housing 10. Taking the first direction w as a counterclockwise direction from the upper left to the lower right as an example, the third magnetic component 19 is positioned on the left side of the ball body 21. During the rotation of the rolling mechanism 20 along the second direction v, that is, during the opening of the loading hole 101, the first magnetic component 24 swings towards the upper left along the second direction v and approaches the third magnetic component 19. The magnetic force between the first magnetic component 24 and the third magnetic component 19 promotes the swing of the first magnetic component 24 along the second direction v. When the loading hole 101 is open, the first magnetic component 24 and the third magnetic component 19 can be directly opposite each other in the left-right direction.

[0104] Optionally, referring to Figure 18, the bracket 15 has a third receiving groove 193 for accommodating a third magnetic element 19. The third magnetic element 19 can be fixedly mounted on the bracket 15. The third receiving groove 193 is formed inside the bowl-shaped structure of the bracket 15. The opening of the third receiving groove 193 can be open towards the ball body 21 to reduce the obstruction between the third magnetic element 19 and the first magnetic element 24 and enhance the magnetic attraction.

[0105] With the loading hole 101 open, the user can move the ball body 21 to make the ball body 21 rotate in the first direction w to overcome the magnetic attraction between the third magnetic force and the first magnetic force, thereby closing the loading hole 101.

[0106] Please refer to Figures 14 and 15. In some embodiments, the distance between the first magnetic element 24 and the third magnetic element 19 is greatest when the ball body 21 closes the loading hole 101, and smallest when the hollow part 22 is connected to the loading hole 101.

[0107] Thus, as the rolling mechanism 20 rotates along the second direction v, the first magnetic element 24 and the third magnetic element 19 gradually approach each other, causing the attraction between the first magnetic element 24 and the third magnetic element 19 to gradually increase as the rolling mechanism 20 rotates along the second direction v. This assists the rolling mechanism 20 in rotating to open the loading hole 101, and a large magnetic attraction force is formed when the hollow part 22 is connected to the loading hole 101, maintaining structural stability.

[0108] Specifically, the first magnetic element 24 gradually moves away from the third magnetic element 19 as the ball body 21 rotates along the first direction w, and gradually moves closer to the third magnetic element 19 as it rotates along the second direction v. The distance between the first magnetic element 24 and the third magnetic element 19 is minimal when the loading hole 101 is open. Therefore, the magnetic attraction between the first magnetic element 24 and the third magnetic element 19 is maximum when the loading hole 101 is open, thus making it less prone to loosening as the hollow portion 22 of the ball body 21 remains in a state where it is opposite and connected to the loading hole 101.

[0109] Optionally, to avoid the aerosol generating matrix being inserted into the space within the housing 10, the minimum distance between the third magnetic element 19 and the first magnetic element 24 is greater than the minimum distance between the second magnetic element 18 and the first magnetic element 24. The resistance to the adsorption of the third magnetic element 19 and the first magnetic element 24 is greater than the resistance to the adsorption of the second magnetic element and the first magnetic element. Therefore, the magnetic force of the third magnetic element 19 is less than the magnetic force of the second magnetic element 18, so that the first magnetic element 24 can overcome the magnetic attraction between itself and the third magnetic element 19 when it rotates with the ball body 21 along the first direction w.

[0110] Furthermore, the third magnetic element 19 can be made of the same material as the second magnetic element 18 and have the same degree of magnetic saturation. The volume of the third magnetic element 19 is slightly smaller than that of the second magnetic element 18.

[0111] Please refer to Figures 16 and 17. In some embodiments, the rolling mechanism 20 includes a first limiting part 212 and a second limiting part 213. The housing 10 is provided with a limiting structure 16. The limiting structure 16 cooperates with the first limiting part 212 when the ball body 21 closes the loading hole 101, and cooperates with the second limiting part 213 when the hollow part 22 communicates with the loading hole 101, so as to limit the position of the rolling mechanism 20.

[0112] Thus, by the limiting structure 16 cooperating with the first limiting part 212 when the ball body 21 closes the loading hole 101, and cooperating with the second limiting part 213 when the hollow part 22 is connected to the loading hole 101, the rotation range of the rolling mechanism 20 along the first direction w and the second direction v is restricted, which is beneficial for the rolling mechanism 20 to remain stationary relative to the housing 10 when the loading hole 101 is closed and open.

[0113] Specifically, referring to Figure 19, the first limiting part 212 and the second limiting part 213 can be disposed on the outer surface of the ball body 21. Correspondingly, the limiting structure 16 is disposed on the opposite side of the surface where the first limiting part 212 and the second limiting part 213 are located. The first limiting part 212 and the second limiting part 213 can be a protrusion, a groove, a buckle, etc., respectively, and correspondingly, the limiting structure 16 is a groove, a protrusion, or a locking block that matches the first limiting part 212 and the second limiting part 213. Optionally, the limiting structure 16 is disposed on the bracket 15.

[0114] Optionally, the first limiting part 212 and the second limiting part 213 are distributed on the same side of the ball body 21 to improve the compactness of the structure.

[0115] Optionally, the first limiting portion 212 and the second limiting portion 213 may also be distributed on different side surfaces of the ball body 21, and may have different structural forms to cooperate with the limiting structure 16. In some extended embodiments, the first limiting portion 212 and the second limiting portion 213 may be distributed in multiple locations on the ball body 21.

[0116] Please refer to Figures 16-19. In some embodiments, the limiting structure 16 includes a limiting rib 161. The first limiting portion 212 and the second limiting portion 213 are spaced apart and protrude from the surface of the ball body 21. The limiting rib 161 abuts against the first limiting portion 212 when the ball body 21 closes the loading hole 101, and abuts against the second limiting portion 213 when the hollow portion 22 is in communication with the loading hole 101.

[0117] Thus, with the first limiting part 212 and the second limiting part 213 spaced apart and protruding from the surface of the ball body 21, the limiting rib 161 abuts against the first limiting part 212 when the ball body 21 closes the loading hole 101, and abuts against the second limiting part 213 when the hollow part 22 is connected to the loading hole 101, thereby effectively limiting the rotation angle range of the rolling mechanism 20, which is beneficial to maintaining the structural stability when the loading hole 101 is open or closed.

[0118] Specifically, the limiting rib 161 protrudes from the surface of the bracket 15 facing the ball body 21. The limiting rib 161 may be cylindrical, prismatic, conical, strip-shaped, or other combined shapes. For example, the limiting rib 161 is a short vertical rib. The first limiting portion 212 and the second limiting portion 213 may be protrusions.

[0119] The limiting rib 161 is located on the rotation path of the first limiting part 212 and the second limiting part 213 as the ball body 21 rotates. The distance between the first limiting part 212 and the second limiting part 213 and the rotating shaft 23 is equal, so that the rotation radius of the first limiting part 212 and the second limiting part 213 is the same. Therefore, the limiting rib 161 can be set at the position where the rotation paths of the first limiting part 212 and the second limiting part 213 coincide, so that it can abut against both the first limiting part 212 and the second limiting part 213.

[0120] Taking the first direction w as a rotation from the upper left to the lower right as an example, the first limiting part 212 is located to the left of the limiting rib 161, and the second limiting part 213 is located to the right of the limiting rib 161. The first limiting part 212 rotates with the ball body 21 along the first direction w and approaches the limiting rib 161 until the first limiting part 212 abuts against the limiting rib 161, causing the ball body 21 to stop rotating due to the restriction of the limiting rib 161. The second limiting part 213 rotates with the ball body 21 along the second direction v and approaches the limiting rib 161 until the second limiting part 213 abuts against the limiting rib 161, causing the ball body 21 to stop rotating due to the restriction of the limiting rib 161.

[0121] Optionally, referring to Figure 18, the surface of the ball body 21 where the first limiting part 212 and the second limiting part 213 are located is a limiting surface 214, which can be a plane. The rotating shaft 23 can be disposed on the limiting surface 214, and the first limiting part 212 and the second limiting part 213 rotate around the rotating shaft 23. The limiting surface 214 is parallel to the plane containing the first direction w and the second direction v. In other embodiments, the extension line of the rotating shaft 23 passes through the limiting surface 214, and the first limiting part 212 and the second limiting part 213 rotate around the intersection of the extension line of the rotating shaft 23 and the limiting surface 214.

[0122] Optionally, the limiting surface 214 is the front or rear surface of the ball body 21.

[0123] Please refer to Figures 16-18. In some embodiments, the housing 10 is formed with a relief groove 152. The relief groove 152 is formed on one side of the ball body 21, and the limiting rib 161 is formed on the groove wall of the relief groove 152. The relief groove 152 is used to provide the activity space for the first limiting part 212 and the second limiting part 213.

[0124] Thus, by providing the first limiting part 212 and the second limiting part 213 with the clearance groove 152, the limiting rib 161 is formed on the groove wall of the clearance groove 152, thereby improving the space utilization rate, avoiding structural interference, and ensuring that the rolling mechanism 20 moves within the preset range.

[0125] Specifically, the inner side of the support 15, which has a bowl-shaped or cup-shaped structure, is partially recessed outward to form a relief groove 152.

[0126] Optionally, the bottom surface of the relief groove 152 is opposite to the limiting surface 214 in the front-back direction, the limiting rib 161 protrudes from the bottom surface of the relief groove 152 to the limiting surface 214 in the front-back direction, the first limiting part 212 and the second limiting part 213 protrude from the limiting surface 214 to the bottom surface of the relief groove 152 in the front-back direction, and the sum of the height of the first limiting part 212 protruding from the limiting surface 214 and the height of the limiting rib 161 protruding is less than the distance between the limiting surface 214 and the bottom surface of the relief groove 152 in the front-back direction.

[0127] Please refer to Figures 11-13. In some embodiments, the ball body 21 includes a covering portion 215 and a movable portion 216. The covering portion 215 and the movable portion 216 together form a hollow portion 22. At least a portion of the surface of the covering portion 215 away from the hollow portion 22 forms a first arcuate surface 2151. The first arcuate surface 2151 is at least partially exposed outside the loading hole 101 when the ball body 21 is closed.

[0128] Thus, with the first arc surface 2151 extending at least partially outside the loading hole 101 when the ball body 21 is closed, the ball body 21 can utilize the space outside the loading hole 101 as its own movement space, thereby saving space inside the aerosol generating device 100. Furthermore, the exposed first arc surface 2151 also indicates the closed state of the loading hole 101, facilitating user operation.

[0129] Specifically, the covering portion 215 and the movable portion 216 are interconnected and surround the hollow portion 22. The inner surface of the ball body 21, that is, the wall surface of the hollow portion 22 formed by the covering portion 215 and the movable portion 216, differs from the straightness or curvature of the outer surface of the ball body 21. Furthermore, even when both the inner and outer surfaces are curved, the curvature of the inner and outer surfaces of the ball body 21 can also be different. Optionally, a cylindrical hollow section is formed inside the ball body 21 as the hollow portion 22, while the outer contour of the ball body 21 is approximately spherical to reduce the space occupied. The outer contour of the ball body 21 can be an incomplete sphere, and the covering portion 215 can be approximately hemispherical.

[0130] With the loading hole 101 closed, as shown in FIG13, the covering part 215 is above the movable part 216, and the covering part 215 covers or blocks the loading hole 101, while the movable part 216 can cover or block the through hole 151 of the bracket 15. With the loading hole 101 open, as shown in FIG12, the covering part 215 and the movable part 216 are opposite each other.

[0131] Referring to Figures 11 and 19, in some embodiments, the rolling mechanism 20 includes a rotating shaft 23 rotatably connected to the housing 10, the extension of which passes through the center of the first arc surface 2151.

[0132] Thus, by having the extension line of the rotating shaft 23 pass through the center of the first arc surface 2151, the first arc surface 2151 remains within the same spherical surface as it rotates with the ball body 21. This restricts the activity space of the covering part 215 to the spherical surface where the first arc surface 2151 is located, improving the space utilization rate inside the aerosol generating device 100 and allowing other components to avoid the activity space of the covering part 215, thereby reducing structural interference.

[0133] Specifically, the extension line of the rotating shaft 23 passes through the center of the first arc surface 2151, the covering part 215 swings relative to the housing 10 around the straight line of the rotating shaft 23, the first arc surface 2151 rotates around its own center, the first arc surface 2151 is always in the same spherical surface during the rotation with the ball body 21, and the covering part 215 is always moving within the spherical surface defined by the first arc surface 2151.

[0134] Please refer to Figures 12 and 13. In some embodiments, the movable part 216 forms a second arc surface 2162 on the side opposite to the first arc surface 2151, and the centers of the first arc surface 2151 and the second arc surface 2162 coincide with each other.

[0135] Thus, the centers of the first arc surface 2151 and the second arc surface 2162 coincide, ensuring that the first arc surface 2151 and the second arc surface 2162 remain within the same spherical surface during the rotation of the ball body 21. This limits the active space occupied by the ball body 21, improves space utilization, and facilitates the design and arrangement of other components inside the aerosol generating device 100, thereby reducing structural interference.

[0136] Specifically, when the covering portion 215 covers the loading hole 101, as shown in FIG13, the first arc surface 2151 and the second arc surface 2162 are opposite to each other in the vertical direction, and the second arc surface 2162 can be opposite to the through hole 151 of the bracket 15. When the hollow portion 22 is connected to the loading hole 101, as shown in FIG12, the first arc surface 2151 and the second arc surface 2162 are opposite to each other in the horizontal direction.

[0137] The center of the first arc surface 2151 is located on the extension line of the rotating shaft 23. The centers of the first arc surface 2151 and the second arc surface 2162 coincide with each other. The first arc surface 2151 and the second arc surface 2162 rotate relative to the housing 10 around the same center. The second arc surface 2162 remains within the same spherical surface as it rotates with the ball body 21, and the movable part 216 also always moves within the spherical surface defined by the second arc surface 2162.

[0138] Furthermore, the first arc surface 2151 and the second arc surface 2162 have the same radius, and they are located within the same sphere. The surface of the ball body 21 between the first arc surface 2151 and the second arc surface 2162 is either a flat surface or a curved surface with a curvature less than that of the first arc surface 2151. Thus, during rotation, the ball body 21 remains within the sphere containing the first arc surface 2151 and the second arc surface 2162, thereby improving space utilization and facilitating the miniaturization of the aerosol generating device 100.
