[0050] Please see Figures 1-3 This application provides a cover structure 100, which includes an end cap 1, a cover plate 2, a transmission rod 3, and a driving mechanism 4. The end cap 1 has an insertion port 11 for connecting to the heating chamber 301 of the aerosol generating device 1000, and for aerosol products to pass through. The cover plate 2 is movably disposed on the end cap 1. One end of the transmission rod 3 is connected to the cover plate 2. The driving mechanism 4 is disposed on the end cap 1 and connected to the other end of the transmission rod 3. The driving mechanism 4 drives the transmission rod 3 to move, causing the cover plate 2 to move between a first position and a second position, so that the cover plate 2 opens or closes the insertion port 11, thereby allowing the cover plate 2 to open or close the heating chamber 301 of the aerosol generating device 1000. With the above structure, the cover structure 100 is less prone to failure after prolonged use or in the event of a drop or severe impact, thus improving the reliability of the cover structure 100 in opening or closing the heating chamber 301.

[0051] In some embodiments, please refer to Figure 4 The drive mechanism 4 includes a pressing component 41 and a rotating disk 42. The rotating disk 42 is rotatably disposed on the side of the end cover 1 away from the insertion port 11, and is connected to the other end of the transmission rod 3. The pressing component 41 is disposed on the rotating disk 42. When the pressing component 41 is pressed, it drives the rotating disk 42 to rotate, thereby driving the transmission rod 3 to move. Power is provided by pressing the pressing component 41 to achieve the rotation of the rotating disk 42.

[0052] In some embodiments, please refer to Figure 2 and Figure 4 The rotating disk 42 is provided with a track groove 421. The end of the transmission rod 3 away from the cover plate 2 is provided with a slide 31. The slide 31 is inserted into the track groove 421 and can slide within the track groove 421. When the rotating disk 42 rotates, the slide 31 and the track groove 421 cooperate to drive the transmission rod 3, so that the transmission rod 3 drives the cover plate 2 to move.

[0053] In some embodiments, please refer to Figure 4 The pressing assembly 41 includes a pressing member 411, a rotor 412, a fixed seat 413, and an elastic member 414. The rotating disk 42 is provided with a first through groove 422. The fixed seat 413 is stacked on the rotating disk 42, and the fixed seat 413 is provided with a second through groove 4131, which connects to the first through groove 422. The rotor 412 is inserted into the first through groove 422 and the second through groove 4131, and the rotor 412 can slide along the first through groove 422 and the second through groove 4131. The elastic member... 414 is disposed in the first through groove 422, the elastic member 414 abuts against one end of the rotor 412, the pressing member 411 is inserted into the second through groove 4131, one end of the pressing member 411 is located outside the second through groove 4131, and the pressing member 411 can slide along the second through groove 4131; wherein, the pressing member 411 is used to push the rotor 412 to slide and guide the rotor 412 to rotate, the fixed seat 413 is used to guide the rotor 412 to rotate, and the rotor 412 is used to drive the rotating disk 42 to rotate. Specifically, when the pressing member 411 is pressed, it slides along the second through groove 4131 to push the rotor 412 to slide. Under the action of the elastic member 414 and the guidance of the pressing member 411, the rotor 412 rotates part of its path, thereby driving the rotating disk 42 to rotate part of its path. When the pressing member 411 is released, under the action of the elastic member 414, the rotor 412 slides along the first through groove 422 and the second through groove 4131 to push the pressing member 411 to slide back to its original position along the second through groove 4131. Under the guidance of the fixed seat 413, the rotor 412 continues to rotate until it reaches its final position, thereby driving the rotating disk 42 to its final position. As an example, the elastic member 414 is a spring.

[0054] For further details, please refer to Figures 2-4 The end cap 1 is provided with a third through hole 12. The end of the rotating disk 42 away from the fixed base 413 passes through the third through hole 12, so that the rotating disk 42 rotates around the third through hole 12.

[0055] In some embodiments, please refer to Figure 4 and Figure 5The pressing member 411 has a first helical tooth 4111 at one end, the rotor 412 has a second helical tooth 4121 at one end, and the sidewall of the second through groove 4131 has a third helical tooth 4132. The first helical tooth 4111 is used to push the second helical tooth 4121 and guide the second helical tooth 4121 to rotate, and the third helical tooth 4132 is used to guide the second helical tooth 4121 to rotate. Specifically, when the pressing member 411 is not pressed, the third helical tooth 4132 engages with the second helical tooth 4121 to limit the rotor 412 and prevent the rotor 412 from rotating, so that the cover plate 2 is kept in the open or closed insertion port 11. When the pressing member 411 is pressed, the first helical tooth 4111 pushes the second helical tooth 4121 to slide, that is, the pressing member 411 pushes the rotor 412 to slide until the second helical tooth 4121 separates from the third helical tooth 4132. Under the action of the elastic member 414 and the guidance of the first helical tooth 4111, the second helical tooth 4121 rotates until it engages with the first helical tooth 4111, so that the rotor 412 rotates part of the path. When the pressing member 411 is released, under the action of the elastic member 414, the rotor 412 slides along the first through groove 422 and the second through groove 4131 until the second helical tooth 4121 abuts against the third helical tooth 4132, and the third helical tooth 4132 guides the second helical tooth to continue rotating until the second helical tooth 4121 engages with the third helical tooth 4132, so that the rotor 412 rotates to the position.

[0056] Furthermore, there are multiple first helical teeth 4111, second helical teeth 4121, and third helical teeth 4132. Multiple first helical teeth 4111 are arranged in a ring at the other end of the pressing member 411, multiple second helical teeth 4121 are arranged in a ring at one end of the pressing member 411, and multiple third helical teeth 4132 are arranged in a ring at the other end of the side wall of the second through groove 4131. Through the cooperation of multiple first helical teeth 4111, second helical teeth 4121, and third helical teeth 4132, the rotor 412 rotates in one direction, thereby enabling the pressing drive cover 2 to open or close the insertion port 11. As an example, there are four first helical teeth 4111, four second helical teeth 4121, and four third helical teeth 4132.

[0057] In some embodiments, please refer to Figure 4 and Figure 5One of the sidewalls of the first through groove 422 and the rotor 412 is provided with a first limiting groove 423, and the other is provided with a first limiting platform 4122, which is inserted into the first limiting groove 423. As an example, the first limiting groove 423 is provided on the sidewall of the first through groove 422 and is connected to the first through groove 422, and the first limiting platform 4122 is provided on the rotor 412. Through the combined action of the first limiting groove 423 and the first limiting platform 4122, the rotor 412 is prevented from rotating relative to the rotating disk 42, and the rotor 412 is used to drive the rotating disk 42 to rotate. One of the sidewalls of the pressing member 411 and the second through groove 4131 is provided with a second limiting groove 4112, and the other is provided with a second limiting platform 4133, which is inserted into the second limiting groove 4112. As an example, a second limiting groove 4112 is disposed on the pressing member 411, and a second limiting platform 4133 is disposed on the side wall of the second through groove 4131. The pressing member 411 is prevented from rotating by the combined action of the second limiting groove 4112 and the second limiting platform 4133.

[0058] In some embodiments, please refer to Figure 4 and Figure 5 The fixed seat 413 is provided with a clearance notch 4134. The end of the transmission rod 3 away from the cover plate 2 is inserted into the clearance notch 4134 to reduce the space occupied by the rotating disk 42.

[0059] In some embodiments, please refer to Figures 1-7 The cover structure 100 includes a top cover 5, which covers the end cover 1 and the drive mechanism 4. The top cover 5 has a first through hole 51 and a second through hole 52. The first through hole 51 is aligned and communicates with the insertion port 11. The pressing member 411 extends out of the top cover 5 through the second through hole 52. The top cover 5 is connected and fixed to the fixing seat 413. The top cover 5 covering the end cover 1 and the drive mechanism 4 makes the cover structure 100 aesthetically pleasing, and the connection and fixation between the top cover 5 and the fixing seat 413 prevents the fixing seat 413 from rotating.

[0060] Furthermore, the top cover 5 is provided with a connecting block 53, and the fixing seat 413 is provided with a connecting groove 4135, into which the connecting block 53 is inserted.

[0061] In some embodiments, please refer to Figure 4 The pressing assembly 41 includes a pressing cap 415, which covers one end of the pressing member 411 and extends from the top cover 5 through the second through hole 52. By increasing the pressing area with the pressing cap 415, the pressure on the user's hand during pressing is reduced, the pressure is dispersed, thereby reducing hand fatigue and discomfort and improving comfort.

[0062] Furthermore, the pressing cap 415 includes a cap body 4151 and an abutting ring edge 4152. The abutting ring edge 4152 is fixed to the side wall of the cap body 4151. The cap body 4151 extends out of the second through hole 52. The abutting ring edge 4152 is used to abut against the surface of the top cover 5 facing the end cover 1 to prevent the pressing cap 415 from disengaging from the top cover 5.

[0063] Furthermore, the surface of the cap body 4151 away from the top cover 5 is provided with an anti-slip structure to increase friction and reduce the possibility of the user's hand coming off the cap 415 when pressing it.

[0064] In some embodiments, please refer to Figure 2 The end cap 1 is provided with a groove 13, which connects to the insertion port 11, and the cover plate 2 is received in the groove 13 to reduce the space occupied.

[0065] For further details, please refer to Figure 2 and Figure 7 The cover plate 2 is provided with a plug hole 21, and the bottom of the groove 13 extends with a first plug post 14. The first plug post 14 is plugged into the plug hole 21, so that the cover plate 2 rotates between a first position and a second position with the first plug post 14 as the center.

[0066] Furthermore, the cover plate 2 is provided with a second insertion post 22, and one end of the transmission rod 3 is provided with an insertion groove 32. The second insertion post 22 is movably inserted into the insertion groove 32 so that the transmission rod 3 is connected to the cover plate 2, thereby causing the transmission rod 3 to move under the drive of the pressing component 41, so as to drive the cover plate 2 to rotate between the first position and the second position.

[0067] In some embodiments, please refer to Figure 2 The end cap 1 is provided with a receiving groove 15, which is connected to the groove 13 and receives the transmission rod 3.
