Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0002] In aerosol generation devices, the flip-top design of the bottom cover is a key functional module for users to replace aerosol-generated products and clean and maintain the internal structure. To ensure the stability and safety of the flipping process, existing technologies generally use mechanical restraint mechanisms (such as ratchet locks, spring clips, or damping hinges) to prevent the bottom cover from accidentally falling off during the flipping process.

[0003] However, the stringent requirements for the machining precision of the components of the limiting mechanism lead to increased manufacturing costs; the precise motion of the limiting mechanism also increases the complexity of the structure, resulting in a cumbersome overall aerosol generation device structure. Utility Model Content

[0004] The purpose of this invention is to provide an aerosol generating device that reduces manufacturing costs and structural complexity while ensuring the overall compactness of the aerosol generating device.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Aerosol generating apparatus, comprising:

[0007] Cover;

[0008] The main body, wherein the cover is rotatably connected to the main body, and the main body is provided with a first friction part;

[0009] A friction element is detachably connected to the cover, the cover being used to drive the friction element to rotate synchronously, and at least a portion of the surface of the first friction part slides in contact with the friction element to provide rotational resistance to the cover.

[0010] As an alternative to the aerosol generating device, the friction member has a second friction part protruding from the surface of the first friction part, the body has an opening for the aerosol generating product to pass through, and the cover has a first state of closing the opening and a second state of opening the opening. During the process of the cover switching from the first state to the second state, the first friction part and the second friction part slide from a non-contact state to a squeezed state.

[0011] As an alternative solution for an aerosol generating device, the cover body is provided with a mounting platform, the mounting platform is provided with two opposing pivot holes, and the aerosol generating device further includes two pivot pins arranged sequentially at intervals along the axial direction and rotatably connected to the two pivot holes respectively, the two opposite ends of the two pivot pins being hinged to the body respectively.

[0012] As an alternative to the aerosol generating device, the aerosol generating device further includes a mounting member detachably connected to the body, the mounting member having a first friction portion protruding from its surface toward the friction member.

[0013] As an alternative to the aerosol generating device, one of the mounting component and the main body is provided with a slot, and the other is provided with a buckle, which is engaged in the slot.

[0014] As an alternative to an aerosol generating device, the main body is provided with two opposing first limiting grooves, and the two opposite ends of the two shaft pins are rotatably disposed in the first limiting grooves.

[0015] As an optional solution for an aerosol generating device, the aerosol generating device further includes a mounting component, which is provided with limiting posts. Two of the limiting posts are respectively inserted into two first limiting grooves, and the two limiting posts and the bottom walls of the two first limiting grooves respectively enclose a space for the two opposite ends of the shaft pin to rotate.

[0016] As an alternative to the aerosol generating device, the mounting platform is provided with a second limiting groove, the friction element is inserted into the second limiting groove, and the two opposite ends of the two shaft pins respectively abut against the two ends of the friction element.

[0017] As an alternative to the aerosol generating device, the bottom wall of the second limiting groove is provided with a limiting protrusion, and the friction element is provided with a receiving groove, with the limiting protrusion placed in the receiving groove.

[0018] As an alternative to the aerosol generating device, the limiting protrusion separates the two shaft pins along the axial direction of the shaft pins, and the opposite ends of the two shaft pins can respectively abut against the limiting protrusion.

[0019] As an alternative to the aerosol generating device, the first friction part extends along the rotation direction of the cover.

[0020] Beneficial effects:

[0021] In this invention, one end of the cover is rotatably connected to one side of the bottom of the main body. When the user needs to replace the aerosol-generating product, the cover can be rotated to expose the opening, allowing the aerosol-generating product to be inserted into the heating chamber inside the main body. A friction element is located near the rotatable connection between the cover and the main body. When the cover is flipped, the friction element rotates with the cover and simultaneously slides against at least a portion of the surface of the first friction part, providing resistance during opening and preventing accidental falls, thus ensuring the stability and safety of the cover flipping process. Furthermore, the direct frictional engagement between the friction element and the first friction part further avoids the need for additional mechanical restraint mechanisms, preventing increased manufacturing costs; it also ensures the overall structural compactness.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] Please see the appendix Figure 1 - Appendix Figure 3 This embodiment relates to an aerosol generating device 10. The aerosol generating device 10 includes a cover 1, a body 2, and a friction element 3. The cover 1 is rotatably connected to the body 2, and the body 2 has a first friction portion 211 extending along the rotation direction of the cover 1. The friction element 3 is detachably connected to the cover 1. The cover 1 drives the friction element 3 to rotate synchronously, and at least a portion of the surface of the first friction portion 211 is used for sliding contact with the friction element 3 to provide rotational resistance to the cover 1.

[0038] It should be noted that this aerosol generating device 10 needs to be used in conjunction with the aerosol generating product 100 so that the aerosol generating product 100 can generate aerosols. The aerosol generating product 100 used in this embodiment has a block structure, specifically a short column block with slightly bulging sides, and the aerosol generating product 100 may have an aerosol generating matrix.

[0039] As used herein, the term "aerosol-generating matrix" refers to a matrix capable of releasing volatile substances to form an inhalable aerosol. An aerosol-generating matrix may include tobacco-containing materials containing volatile tobacco flavor compounds that are released from the substrate upon heating. Specifically, an aerosol-generating matrix may be an aerosol-generating matrix containing liquid tobacco or solid tobacco. Alternatively, an aerosol-generating matrix may include non-tobacco materials. An aerosol-generating matrix may also include an aerosol-forming agent. Examples of suitable aerosol-forming agents are glycerol and propylene glycol.

[0040] Specifically, the aerosol generating device 10 employs a method of rotating the cover 1 from the bottom of the main body 2. An opening for placing and removing the aerosol generating product 100 is adaptively provided at the bottom of the main body 2, and one end of the cover 1 is rotatably connected to one side of the bottom of the main body 2. When the user needs to replace the aerosol generating product 100, the cover 1 can be rotated to expose the opening, allowing the aerosol generating product 100 to be inserted into the heating chamber inside the main body 2, or the deactivated aerosol generating product 100 to be removed through the opening.

[0041] Furthermore, the friction element 3 is located near the rotatable connection between the cover 1 and the body 2. When the cover 1 is flipped, the friction element 3 rotates with the cover 1 and simultaneously engages in sliding contact with at least a portion of the surface of the first friction part 211. This provides resistance during the opening of the cover 1, preventing accidental falls and ensuring the stability and safety of the cover 1 during the flipping process. Simultaneously, by directly utilizing the frictional engagement between the friction element 3 and the first friction part 211, the need for additional mechanical restraint mechanisms (such as ratchet locks, spring clips, or damping hinges) can be avoided, preventing increased manufacturing costs and ensuring the overall structural compactness.

[0042] Optionally, the friction member 3 has a second friction part 31 protruding from the surface of the first friction part 211, and the cover 1 has a first state with the opening closed and a second state with the opening open. During the process of the cover 1 switching from the first state to the second state, the first friction part 211 and the second friction part 31 slide from a non-contact state to a squeezed state.

[0043] Specifically, the structure of the first friction part 211 is adaptively designed according to the rotation angle range of the cover 1 relative to the body 2. In this embodiment, since the maximum rotation angle of the cover 1 relative to the body 2 is 90°, the friction surface of the first friction part 211 is 1 / 4 the size of a sphere. During the process of the cover 1 rotating from the first state to the second state, the first friction part 211 and the second friction part 31 gradually transition from a non-contact state (i.e., maintaining a certain gap) to a contact and compression state (i.e., forming interference). In the compression state, the elasticity of the first friction part 211 and / or the second friction part 31 ensures both compression and rotation of the cover 1 relative to the body 2. During the process of the cover 1 rotating from the second state to the first state, the first friction part 211 and the second friction part 31 transition from a contact and compression state to a non-contact state until the cover 1 is reset. After the cover 1 is reset, it can be connected to the body 2 by a snap-fit ​​method, a threaded connection method, or even by the magnetic force of a magnetic component to prevent loosening.

[0044] In this embodiment, by adjusting the relative position of the friction surface of the first friction part 211 and the second friction part 31 or by simply changing the thickness of the friction surface of the first friction part 211, the change in the sliding state of the first friction part 211 and the second friction part 31 from non-contact state to extrusion state during the process of the cover 1 switching from the first state to the second state can be adapted.

[0045] In this embodiment, the sliding motion between the first friction part 211 and the second friction part 31 from a non-contact state to a compression state facilitates the user's perception of changes in resistance. Furthermore, when the frictional resistance exceeds the force of gravity, the cover 1 can be suspended at a certain angle relative to the body 2.

[0046] Optionally, the aerosol generating device 10 further includes a mounting member 21, which is detachably connected to the body 2, and the mounting member 21 protrudes from the surface of the friction member 3 to form a first friction part 211.

[0047] Specifically, the mounting member 21 has a 1 / 4 spherical curved surface structure. The mounting member 21 can be screwed and fixed to the body 2 by threaded fasteners. Specifically, the mounting member 21 extends in a direction away from the rotating connection part to form a connection end, and the connection end is connected to the body 2 by threaded fasteners. The mounting member 21 has a protrusion on the side surface facing the friction member 3 to form a first friction part 211.

[0048] In this embodiment, the first friction part 211 is disposed on the body 2 and a detachable connection method is adopted, which makes it easier to remove and replace the mounting part 21 from the body 2. This facilitates the user to replace the mounting part 21 after the first friction part 211 wears out, thereby avoiding the need to repair or replace parts of the body 2 and effectively reducing the maintenance cost of this aerosol generating device 10.

[0049] Furthermore, one of the mounting component 21 and the main body 2 is provided with a slot 22, and the other is provided with a buckle 212, which is engaged in the slot 22.

[0050] Specifically, a slot 22 is provided on the side wall of the main body 2, and a buckle 212 is formed on the mounting part 21, which is engaged in the slot 22.

[0051] In this embodiment, the snap-fit ​​212 and the slot 22 can be used in conjunction with the above threaded connection method. The snap-fit ​​of the snap-fit ​​212 and the slot 22 not only facilitates the structural positioning before the threaded connection, but also prevents the snap-fit ​​of the snap-fit ​​212 and the slot 22 from being accidentally unlocked, effectively improving the reliability and stability of the connection between the mounting part 21 and the body 2.

[0052] Please see the appendix Figure 4 Optionally, the cover 1 is provided with a mounting platform 11, and the mounting platform 11 is provided with two opposing pivot holes 111. The aerosol generating device 10 also includes two pivot pins 4 arranged sequentially along the axial direction and rotatably connected to the two pivot holes 111 respectively. The two ends of the two pivot pins 4 that are opposite to each other are respectively hinged to the body 2.

[0053] Specifically, the mounting platform 11 is a block structure integrally formed on the cover 1. At the same time, two opposing rotating shaft holes 111 with circular cross sections are formed on the mounting platform 11. The two rotating shaft holes 111 are used to accommodate two shaft pins 4 respectively. Part of the two shaft pins 4 are placed in the rotating shaft holes 111, and the other part is hinged to the body 2, thereby realizing the rotational connection of the cover 1 relative to the body 2.

[0054] This embodiment adopts a dual-axis structure. Compared with the single-axis structure, although the structure is relatively complex and has more parts, it is conducive to assembly and thus improves assembly efficiency.

[0055] Furthermore, the main body 2 is provided with two opposing first limiting grooves 23, and the two opposite ends of the two shaft pins 4 are rotatably provided in the first limiting grooves 23.

[0056] Specifically, another part of the two pins 4 can be accommodated in the first limiting groove 23, and is rotatably disposed within the first limiting groove 23.

[0057] In this embodiment, the first limiting groove 23 is used to provide a limit for the shaft pin 4 during installation to ensure assemblability.

[0058] Furthermore, the mounting component 21 is provided with limiting posts 213, and the two limiting posts 213 are respectively inserted into the two first limiting grooves 23. The two limiting posts 213 and the bottom walls of the two first limiting grooves 23 respectively form a space for the two opposite ends of the shaft pin 4 to rotate.

[0059] Specifically, two limiting posts 213 are protruded and extended on the mounting part 21 corresponding to the two first limiting grooves 23. After the mounting part 21 is assembled, the two limiting posts 213 are placed in the two first limiting grooves 23. At the same time, the two limiting posts 213 and the bottom wall of the two first limiting grooves 23 constitute the rotation space of the shaft pin 4, so that the rotation of the shaft pin 4 is always limited within the rotation space, ensuring the stability of the rotation of the shaft pin 4.

[0060] Optionally, the mounting platform 11 is provided with a second limiting groove 112, the friction element 3 is inserted into the second limiting groove 112, and the two opposite ends of the two shaft pins 4 respectively abut against the two ends of the friction element 3.

[0061] Specifically, a portion of the structure of the friction element 3 is inserted into the second limiting groove 112, and the second friction part 31 of the friction element 3 is exposed outside the second limiting groove 112. The second limiting groove 112 provides a limit for the friction element 3 so that the mounting platform 11 can drive the friction element 3 to rotate.

[0062] In this embodiment, the second limiting groove 112 is connected to the rotating shaft hole 111. Before the friction member 3 is inserted into the second limiting groove 112, the two shaft pins 4 are first inserted into the corresponding rotating shaft holes 111 through the second limiting groove 112. Then, a tool is used to push one end of the two shaft pins 4 from inside the second limiting groove 112, so that the other ends of the two shaft pins 4 are pushed into the first limiting groove 23 respectively. Finally, the friction member 3 is inserted into the second limiting groove 112. The above installation method is simple and convenient, and greatly improves the installation efficiency of the rotating parts. In addition, by having both ends of the friction member 3 abut against the two shaft pins 4, and at the same time using the inner wall of the first limiting groove 23, the shaft pins 4 can be easily limited in the axial direction, preventing the shaft pins 4 from moving in the axial direction.

[0063] Optionally, the bottom wall of the second limiting groove 112 is provided with a limiting protrusion 113, and the friction member 3 is provided with a receiving groove 32, with the limiting protrusion 113 placed in the receiving groove 32.

[0064] Specifically, the limiting protrusion 113 is a bar-shaped structure. Correspondingly, the friction member 3 forms a receiving groove 32 at one end relative to the second friction part 31, so that the limiting protrusion 113 is placed in the receiving groove 32.

[0065] Furthermore, the limiting protrusion 113 separates the two pins 4 along the axial direction of the pin 4, and the two opposite ends of the two pins 4 can respectively abut against the limiting protrusion 113.

[0066] In this embodiment, the setting of the limiting protrusion 113 not only facilitates the limiting of the friction member 3, but also helps the two shaft pins 4 to be separated in advance after being placed into the second limiting groove 112, thereby facilitating the insertion of a tool between the two shaft pins 4 to push the shaft pins 4.

[0067] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
