[0022] Figure 1 An aerosol generation system 1 according to some embodiments of the present invention is shown. The aerosol generation system 1 may include an aerosol generation device 100 and an aerosol generation article 200. The aerosol generation article 200 is movably inserted into the aerosol generation device 100, facilitating removal and replacement with a new aerosol generation article 200 after heating is complete. The aerosol generation device 100 can heat the aerosol generation article 200 inserted therein after being powered on, to release the aerosol extract in the aerosol generation article 200 in a non-combustible state.

[0023] In some embodiments, the aerosol generating article 200 may be cylindrical. Of course, in other embodiments, the aerosol generating article 200 may also be in other columnar shapes such as elliptical columnar or polygonal columnar. The aerosol generating article 200 may include solid materials in the form of strips, flakes, or granules made from the leaves and / or stems of plants (such as tobacco or tea), and aroma components may be further added to the solid material.

[0024] like Figures 2 to 4 as well as Figure 9 As shown, the aerosol generating device 100 includes a housing 10 and a heating element (not shown), a circuit board (not shown), and a battery 20 disposed within the housing 10. The circuit board is electrically connected to the heating element and the battery 20, respectively. The circuit board is equipped with related control circuitry for controlling the power supply to and from the heating element by the battery 20.

[0025] The outer casing 10 includes a housing 11 with an opening at one end and a top cover 12 covering the opening of the housing 11. The housing 11 is cylindrical, such as a square cylinder, a round cylinder, or an elliptical cylinder. A receiving cavity 310 for accommodating at least a portion of the aerosol generating article 200 is formed inside the housing 11, and the receiving cavity 310 has an opening 311 at the end facing the top cover 12.

[0026] The top cover 12 is fixedly disposed on the upper end of the housing 11. The top cover 12 is provided with an insertion port 120 for inserting the aerosol generating article 200 into the receiving cavity 310. The aerosol generating article 200 can be at least partially inserted into the receiving cavity 310 for heating via the insertion port 120. The heating element heats up after being energized, thereby heating the aerosol generating article 200 contained in the receiving cavity 310.

[0027] The heating method used by the heating component is not limited; for example, it can use one or more of the following: resistance heating, electromagnetic heating, infrared heating, laser heating, microwave heating, etc.

[0028] In some embodiments, the heating element may be a tubular heating element capable of heating around the aerosol generating article 200. In other embodiments, the heating element may also be a needle-shaped or columnar heating element that can be at least partially inserted into the aerosol generating article 200 for heating.

[0029] In some embodiments, the aerosol generating apparatus 100 may include a receiving tube 30 disposed in the housing 11, the inner wall surface of the receiving tube 30 defining at least a portion of the receiving cavity 310.

[0030] The housing 11 is configured with two mutually perpendicular longitudinal directions Z, a first transverse direction X, and a second transverse direction Y. The longitudinal direction Z is parallel to the axis of the accommodating cavity 310. The battery 20 and the accommodating cavity 310 can be arranged side-by-side in the second transverse direction Y. Of course, in other embodiments, the battery 20 and the accommodating cavity 310 can also be arranged side-by-side in the longitudinal direction Z.

[0031] like Figures 4 to 9 As shown, the aerosol generating apparatus 100 includes a movable component 50 and a rotation drive component 40 connected to the movable component 50. The rotation drive component 40 is at least partially disposed in and rotatably connected to the housing 11. The movable component 50 is at least partially disposed between the opening 311 and the insertion port 120. The movable component 50 is connected to the rotation drive component 40 and is movable relative to the upper cover 12 under the drive of the rotation drive component 40 to cover or expose the opening 311.

[0032] In some embodiments, the moving component 50 includes at least two moving parts 51 connected to the rotation drive component 40. These at least two moving parts 51 are capable of moving closer or further apart under the influence of the rotation drive component 40 to cover or expose the opening 311. Alternatively, in other embodiments, the moving component 50 may include only one moving part 51, which the rotation drive component 40 can move back and forth to cover or expose the opening 311.

[0033] The rotation drive assembly 40 can rotate back and forth between a first position and a second position about the central axis of the accommodating cavity 310. For example... Figure 2 , Figure 4 as well as Figure 5 As shown, when the rotation drive assembly 40 is in the first position, at least two moving parts 51 are relatively far apart, and a communication port 510 is formed between the at least two moving parts 51. The opening 311 of the accommodating cavity 310 is connected to the insertion port 120 through the communication port 510. The aerosol generating article 200 can be inserted into the accommodating cavity 310 in sequence through the insertion port 120 and the communication port 510.

[0034] like Figure 3 as well as Figure 6 As shown, when the rotation drive assembly 40 is in the second position, at least two moving parts 51 are relatively close to each other, thereby covering the opening 311 and preventing dust and other debris from entering the receiving cavity 310, thus achieving a dustproof effect.

[0035] For example Figure 4 , Figure 9 , Figure 10 As shown, a rotating groove 111 may be provided through the side wall of the housing 11. The rotation drive assembly 40 may include a rotating shaft 42 slidably disposed in the rotating groove 111 and a turntable 41 fixedly connected to the rotating shaft 42. The rotating groove 111 may be arc-shaped, and the arc-shaped rotating groove 111 is coaxially disposed with the receiving cavity 310, so that the rotating drive assembly 40 can only rotate around the central axis of the receiving cavity 310. The user can switch the position of the rotating drive assembly 40 by rotating the rotating shaft 42 in the rotating groove 111.

[0036] In some embodiments, the rotation drive assembly 40 may further include a paddle 43 disposed outside the housing 11, and the two ends of the rotating shaft 42 are fixedly connected to the paddle 43 and the turntable 41, respectively. The user can rotate the rotating shaft 42 and the turntable 41 by moving the paddle 43, which is convenient and comfortable for the user and has a certain degree of playability.

[0037] In some embodiments, the outer surface of the housing 11 may be recessed with a receiving groove 112, the receiving groove 112 being arc-shaped, and the paddle 43 can rotate back and forth in the receiving groove 112. Of course, in other embodiments, the receiving groove 112 may be omitted.

[0038] The pivot 42 can be integrally formed with the paddle 43 or the turntable 41; or the pivot 42 can be an independent component, which is formed separately and then assembled with the paddle 43 and the turntable 41.

[0039] The turntable 41 is disposed inside the housing 11 and has an insertion hole 410 that communicates with the receiving cavity 310. The turntable 41 can be at least partially rotatably fitted together with the receiving tube 30 to constrain and control the movement of the turntable 41, so that the turntable 41 can only rotate around the central axis of the receiving tube 30.

[0040] In some embodiments, the turntable 41 may include a sleeve 411 and an outer flange 412 extending outward from one end of the sleeve 411 toward the insertion port 120. The upper end of the receiving tube 30 has an annular portion 312, and the sleeve 411 is rotatably disposed in the annular portion 312. It will be understood that in other embodiments, the sleeve 411 may also be rotatably fitted over the annular portion 312.

[0041] In some embodiments, the turntable 41 may also include a protrusion 413 protruding outward from the outer wall of the sleeve 411, and the rotating shaft 42 is fixedly connected to the protrusion 413. The connection method includes, but is not limited to, various connection methods such as plugging, welding, bonding, riveting, and integral molding.

[0042] A notch 3120 is provided on one side of the annular portion 312 so that the protrusion 413 can rotate back and forth in the notch 3120.

[0043] At least two movable members 51 are connected to the turntable 41 and are capable of moving towards or away from the central axis of the receiving cavity 310 under the drive of the turntable 41. In this embodiment, there are two movable members 51, which are centrally symmetrically distributed with respect to the central axis of the receiving cavity 310. Each movable member 51 includes a generally semi-circular cover plate 511, the planar sides of which can be fitted together. When the planar sides of two semi-circular cover plates 511 are fitted together, they form a circular cover plate, thereby sealing the receiving cavity 310. It is understood that in other embodiments, there may be three or more movable members 51.

[0044] The movable component 51 may be provided with a pin 513, and the turntable 41 is provided with two slots 4121 for accommodating the pins 513 of the two movable components 51 respectively. The pins 513 and slots 4121 cooperate to enable the turntable 41 to drive the movable components 51 to open and close.

[0045] The insertion post 513 is preferably cylindrical, but can also be elliptical or other shapes. The slot 4121 can be disposed on the outer flange 412, which has a large radial dimension to provide sufficient space for the slot 4121. The slot 4121 can have a certain extension length to provide the insertion post 513 with a certain amount of movement space. In some embodiments, the slot 4121 can be a racetrack shape extending radially along the receiving cavity 310 / outer flange 412, with two slots 4121 located on opposite radial sides of the receiving cavity 310 / outer flange 412. The insertion post 513 can slide within the slot 4121. Figure 7 , Figure 8 As shown, the insert 513 can slide from one end of the slot 4121 to the other end.

[0046] Understandably, in other embodiments, the insert 513 may also be formed on the turntable 41, and correspondingly, the slot 4121 may be formed on the moving part 51, which can also achieve the transmission effect.

[0047] like Figure 9 , Figure 11 , Figure 12 As shown, the upper cover 12 may have a first guide structure 1211 for constraining the translational movement of the movable member 51. In this embodiment, there are two movable members 51, and correspondingly, two first guide structures 1211 are formed on the upper cover 12 to constrain the two movable members 51 to perform translational movement respectively. The two first guide structures 1211 may be located on the radial sides of the socket 120 respectively.

[0048] Accordingly, the movable member 51 may include a second guide structure 5121 that slides with the first guide structure 1211. At least one of the first guide structure 1211 and the second guide structure 5121 is linear and can extend in a direction parallel to the radial direction of the socket 120. The extension direction of the first guide structure 1211 and / or the second guide structure 5121 is parallel to the first transverse direction X, so that the movable member 51 can perform translational movement in a direction parallel to the first transverse direction X.

[0049] In this embodiment, the first guide structure 1211 is a guide groove, and the second guide structure 5121 is a guide protrusion. The guide protrusion is slidably disposed in the guide groove to restrict the moving member 51 to only perform translational movement. Preferably, the translational distance that each moving member 51 can perform is equal to or greater than the radius of the opening 311, so that when two moving members 51 approach or move away from each other, the opening 311 can be fully covered or exposed.

[0050] In some embodiments, the movable member 51 includes a guide portion 512 disposed on one radial side of the cover plate 511. The guide portions 512 of the two movable members 51 are respectively located on both radial sides of the receiving cavity 310.

[0051] The guide portion 512 extends in the same direction as the first guide structure 1211, and the second guide structure 5121 can be formed by the guide portion 512 protruding towards the upper surface of the upper cover 12. The second guide structure 5121 can be a sliding rib extending in the same direction as the first guide structure 1211. Of course, the second guide structure 5121 can also be a slider or a sliding column, as long as it can slide in the second guide structure 5121.

[0052] Understandably, in other embodiments, the first guide structure 1211 may also be a guide protrusion (e.g., a rib, slider, or column), and correspondingly, the second guide structure 5121 may be a guide groove.

[0053] The top cover 12 may include an inner cover 121 and an outer cover 122 covering the inner cover 121. The outer cover 122 cooperates with the housing 11 to at least partially conceal the inner cover 121 within the housing 10. A first guide structure 1211 may be formed on the lower surface of the inner cover 121.

[0054] The upper cover 12 is composed of an inner cover 121 and an outer cover 122. The first guide structure 1211 can be easily manufactured on the inner cover 121, and the inner cover 121 and the outer cover 122 can each be made of suitable materials as needed, which facilitates the manufacturing process. Of course, in other embodiments, the upper cover 12 can also be a single integral component.

[0055] The rotation drive assembly 40 and the moving assembly 50 are disposed on one side of the housing 11 in the second transverse Y direction. The rotation drive assembly 40 controls the moving assembly 50 to perform translational movement, with the translational direction parallel to the first transverse X direction. This saves space on the other side of the housing 11 in the second transverse Y direction, making it easier to install other interactive structures such as lights, buttons, and screens on the other side of the housing 11. In addition, since the moving assembly 50 does not have an automatic reset, the risk of the aerosol-generated product 200 breaking within the accommodating cavity 310 can be avoided.

[0056] The above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
