[0002] In related technologies, a switching assembly used in an aerosol generating device includes a housing, a shielding part, and an operating part. One end of the shielding part is typically rotatably mounted to the housing via a rotating shaft, and the operating part drives the shielding part to rotate, thereby opening or closing the through hole on the housing. However, when the size of the housing changes, and the switching assembly is used with a housing of a different size, there is a situation where the shielding part of the switching assembly cannot cover the through hole. This results in low versatility of the switching assembly. Utility Model Content

[0032] In the switch assembly of this application embodiment, a drive platform protrudes from the side wall of the knob and is driven to connect with the blocking part.

Furthermore, this motion transmission method has a simple structure and can accurately control the position of the blocking part according to the user's operating intention, ensuring the normal functioning of the switch assembly. When the user rotates the knob, the drive platform rotates accordingly and drives the blocking part to slide, thereby opening or closing the through hole. This design of driving the blocking part to slide by rotating the knob reduces the operating space, making the switch assembly structure more compact. This design also ensures that when the switch assembly is used in a housing with varying dimensions, the blocking part can always cover the through hole, improving the versatility of the switch assembly. In addition, the rotation of the knob provides more precise operational feedback; the user can perceive the degree of drive on the blocking part by the rotation angle, thereby more accurately controlling the opening or closing state of the through hole and meeting the user's needs for the through hole opening degree. Rotation also reduces the possibility of accidental opening or closing of the through hole due to misoperation.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0048] In related technologies, when the dimensions of the housing change, applying existing switch assemblies to the housing with altered dimensions results in an increased distance between the through-hole and the axis of rotation, making it impossible for the blocking part to cover the through-hole. Therefore, the switch assemblies in related technologies have low versatility.

[0049] Based on this, this application provides a switch assembly, please refer to... Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the switching assembly provided in an exemplary embodiment of this disclosure; Figure 2 yes Figure 1 An exploded view of the switch assembly shown. Figure 3 This is a schematic diagram of the structure of the opening through hole of the switch assembly provided in an exemplary embodiment of this disclosure. The switch assembly 10 includes a housing 1, a shielding part, and an operating part 3.

[0050] The housing 1 has a through hole 11. The shape of the housing 1 can be set as needed, and this application does not limit it. In addition, the shape of the cross-section of the through hole 11 can be set as needed, for example, it can be circular, square, elliptical or other polygonal, etc. Specifically, this application does not limit the shape of the cross-section of the through hole 11.

[0051] The shielding part is slidably mounted on the housing 1. The shape of the shielding part can be set as needed, and this application does not limit it.

[0052] The operating unit 3 includes a knob 31 and a drive platform 32 protruding from the side wall of the knob 31. The knob 31 is rotatably mounted on the housing 1, and the drive platform 32 is driven to connect with the blocking part. The drive platform 32 is adapted to drive the blocking part to slide.

[0053] It should be noted that the shape of the drive stage 32 can be set as needed, and this application does not limit it. Furthermore, the method of drive connection between the drive stage 32 and the blocking part can be selected as needed. For example, in one embodiment, the drive stage 32 can be directly drive-connected to the blocking part. In another embodiment, the drive stage 32 and the blocking part can be indirectly drive-connected through other structures. Specifically, this application does not limit it.

[0054] In the switch assembly 10 of this application embodiment, a drive platform 32 protrudes from the side wall of the knob 31 and is driven to connect with the blocking part. This design cleverly transforms the rotational movement of the knob 31 into the sliding movement of the blocking part. This design ensures smooth movement of the blocking part and avoids jamming. In addition, this motion transmission method has a simple structure and can accurately control the position of the blocking part according to the user's operating intention, ensuring the normal functioning of the switch assembly 10. When the user rotates the knob 31, the drive platform 32 rotates accordingly and drives the blocking part to slide, thereby opening or closing the through hole 11. This design of driving the blocking part to slide by rotating the knob 31 reduces the operating space, making the switch assembly 10 more compact. The design of driving the blocking part to slide by rotating the knob 31 also ensures that when the switch assembly is used in a housing 1 with a changed size, the blocking part can always cover the through hole 11, improving the versatility of the switch assembly 10. Furthermore, the rotation of knob 31 provides more precise operational feedback. Users can perceive the degree of drive on the blocking part by the rotation angle, thereby more accurately controlling the opening or closing state of through hole 11 and meeting the user's needs for the opening degree of through hole 11. Rotation also reduces the possibility of accidental operation causing the blocking part to open or close through hole 11.

[0055] Combination Figure 4 , Figure 4This is a schematic diagram of the structure of the switch assembly closing the through hole provided in an exemplary embodiment of this disclosure. In some embodiments, the blocking part includes a first blocking block 21 and a second blocking block 22 that are slidably mounted on the housing 1. The driving platform 32 can drive the first blocking block 21 and the second blocking block 22 to move closer to each other to close the through hole 11 or move further apart to open the through hole 11. Thus, by rotating the knob 31 to drive the driving platform 32 to rotate, the driving platform 32 drives the first blocking block 21 and the second blocking block 22 to move closer or further apart to control the opening and closing of the through hole 11. This method can control the moving distance of the blocking blocks by controlling the rotation angle, thereby precisely controlling the opening or closing size of the through hole 11 to meet user needs. By using two blocking blocks to cooperate in controlling the opening or closing of the through hole 11, the space required for the movement of the first blocking block 21 and the second blocking block 22 is reduced, thereby making the overall structure of the switch assembly 10 more compact while ensuring the functionality.

[0056] It should be noted that, in one embodiment, the driving stage 32 can simultaneously drive the first blocking block 21 and the second blocking block 22 to move, so that the first blocking block 21 and the second blocking block 22 move closer to each other to close the through hole 11 or move further apart to open the through hole 11. Specifically, this application does not limit the specific manner in which the driving stage 32 drives the first blocking block 21 and the second blocking block 22 to move closer to each other to close the through hole 11 or move further apart to open the through hole 11.

[0057] In other embodiments, the number of the first blocking block 21 and the second blocking block 22 can be selected as needed. For example, in one embodiment, one or more first blocking blocks 21 can be provided. One or more second blocking blocks 22 can also be provided. Specifically, this application does not limit this.

[0058] In some embodiments, the switch assembly 10 further includes a transmission unit 4, which is tractively connected to the first blocking block 21 and the second blocking block 22. The drive platform 32 can drive the first blocking block 21 to slide, and the first blocking block 21 can drive the second blocking block 22 to slide via the transmission unit 4. Thus, by simply driving the first blocking block 21 to slide via the drive platform 32, the second blocking block 22 can be moved synchronously via the transmission unit 4, thereby opening or closing the through hole 11. This design reduces the number of directly driven components, simplifies the operation process, and allows the user to control the linkage between the first blocking block 21 and the second blocking block 22 simply by operating the drive platform 32, reducing the complexity and difficulty of operation. By transmitting the power of the first blocking block 21 to the second blocking block 22 via the transmission unit 4, the movement of the two blocking blocks can be ensured to be highly synchronized. This synchronous control can precisely control the opening and closing degree of the through hole 11, avoiding problems such as uneven opening or incomplete closing of the through hole 11 due to asynchronous movement of the blocking blocks, thus improving the control accuracy of the switch assembly 10. The transmission unit 4 enables power transmission between the first blocking block 21 and the second blocking block 22, eliminating the need for an independent drive mechanism for each second blocking block 22. This reduces the number of components inside the switch assembly 10 and makes the entire structure more compact.

[0059] Combination Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of the operating unit provided in an exemplary embodiment of this disclosure. Figure 6 yes Figure 5 The diagram shows a cross-sectional view of the operating part. In some embodiments, the drive platform 32 is provided with a drive groove 33. Along the radial direction of the knob 31, the shortest distance between the drive groove 33 and the center line of the knob 31 varies at different positions. The first blocking block 21 includes a first blocking plate 211 and a first connecting post 212. The first connecting post 212 protrudes axially from the first blocking plate 211 along the through hole 11. The end of the first connecting post 212 away from the first blocking plate 211 is slidably installed in the drive groove 33. Thus, when the knob 31 rotates, the drive platform 32 rotates accordingly. Since the shortest distance between the drive groove 33 and the center line of the knob 31 varies at different positions, when the first connecting post 212 slides in the drive groove 33, its position changes with the rotation of the drive platform 32. This change causes the first connecting post 212 to be displaced relative to the knob 31 in the radial direction of the knob 31, thereby converting the rotational motion of the knob 31 into the linear sliding motion of the first blocking plate 211. This motion conversion method is simple and effective.

[0060] In addition, the drive platform 32 is equipped with a drive slide groove 33. The first blocking block 21 is slidably connected to the drive slide groove 33 via the first connecting post 212. This structural design is compact, makes full use of space, reduces the overall volume of the switch assembly 10, and facilitates installation and use in limited space. The first connecting post 212 protrudes axially from the first blocking plate 211 along the through hole 11 and is slidably installed in the drive slide groove 33. This installation method is simple and direct and easy to assemble. At the same time, the drive slide groove 33 guides and limits the first connecting post 212, ensuring the stability and accuracy of the first blocking block 21 during the sliding process, and preventing the blocking block from shaking or deviating from the predetermined trajectory during movement. When the user rotates the knob 31, they can feel a relatively smooth and stable operating feel through the cooperation between the drive slide groove 33 and the first connecting post 212. The design of the drive slide groove 33 makes the resistance encountered by the first blocking block 21 during the sliding process uniform, reducing the jamming and stuttering feeling during operation and improving the user's operating experience.

[0061] It should be noted that the shape and size of the drive slide 33 can be precisely designed. By controlling the variation law of the shortest distance between different positions of the drive slide 33 and the center line of the knob 31, the sliding trajectory and speed of the first connecting post 212 in the drive slide 33 can be precisely controlled, thereby precisely controlling the sliding distance and speed of the first baffle 211, and meeting the requirements of the degree and speed of opening or closing of the through hole 11 in different scenarios.

[0062] In some embodiments, the drive groove 33 is configured as an arc-shaped groove. This arc-shaped groove design ensures that the first connecting post 212 slides along a smooth, continuous curve. Compared to straight grooves or other irregularly shaped grooves, the arc-shaped groove reduces the impact and vibration of the connecting post during sliding, making the movement of the first blocking block 21 more stable and smooth, avoiding noise and component wear caused by unstable movement, and extending the service life of the switch assembly 10. The arc-shaped groove can fully utilize the space around the knob 31, achieving a longer sliding stroke within a limited space. Compared to straight grooves, the arc-shaped groove can increase the sliding distance of the connecting post without increasing the diameter of the knob 31, thereby meeting the need for a larger range of motion of the first blocking block 21 and making the overall structure of the switch assembly 10 more compact. When the user rotates the knob 31, the first connecting post 212 slides within the arc-shaped groove, and this smooth movement provides the user with a smooth and comfortable operating feel. Users can feel the coordination and consistency between the rotation of knob 31 and the movement of the first blocking block 21, enhancing the pleasure and controllability of operation and improving the user experience of the switch assembly 10. The curved shape of the arc groove can disperse the stress on the connecting post during sliding, avoiding stress concentration at the edge or specific location of the drive slide 33. This helps reduce wear and damage to the drive slide 33 and the first connecting post 212, improving the reliability and durability of the switch assembly 10, and reducing maintenance costs and replacement frequency.

[0063] It should be noted that by reasonably designing the radius of curvature and arc length of the arc groove, the sliding speed and acceleration of the first connecting post 212 within the groove can be precisely controlled. During the rotation of the knob 31, the speed and acceleration of the first connecting post 212 vary at different positions within the arc groove, thus allowing adjustment of the opening or closing speed of the first blocking block 21 according to actual needs. For example, in scenarios requiring rapid opening or closing of the through hole 11, a suitable arc groove shape can be designed to achieve rapid movement; similarly, in scenarios requiring slow and precise adjustment, the arc groove design can also achieve the desired effect. Furthermore, in other embodiments, the driving groove 33 can also be a straight groove, or a combination of straight and arc grooves, etc. Specifically, this application does not limit this.

[0064] In some embodiments, the drive slide 33 includes a first arc-shaped groove segment 331 and a second arc-shaped groove segment 332 connected in sequence, with the curvatures of the first arc-shaped groove segment 331 and the second arc-shaped groove segment 332 being set differently. Thus, a natural transition and pause point is formed at the connection point of the first arc-shaped groove segment 331 and the second arc-shaped groove segment 332 with different curvatures. When the user rotates the knob 31 to drive the first connecting column 212 to slide within the drive slide 33, they can feel the gear shift through the resistance of the knob 31 rotation and the change in the movement of the connecting column between the groove segments. When the connecting column moves from the first arc-shaped groove segment 331 into the second arc-shaped groove segment 332, due to the change in curvature, the user will clearly feel the change in the resistance of the knob 31 rotation. This operational feedback helps the user accurately judge the current gear status, improving the controllability and accuracy of the operation.

[0065] Combination Figure 7 , Figure 7 This is a schematic diagram of the transmission unit provided in an exemplary embodiment of this disclosure. In some embodiments, the transmission unit 4 is rotatably mounted on the housing 1 about the axis of the through hole 11. The transmission unit 4 is provided with a through hole 41 to expose the through hole 11, thus ensuring that the through hole 11 can work normally when needed. The transmission unit 4 is provided with a first strip hole 42 extending through the through hole 11 along its axial direction. Along the radial direction of the through hole 11, the shortest distance between the first strip hole 42 and the center line of the through hole 11 is different at different positions. The end of the first connecting post 212 away from the first baffle plate 211 passes through the first strip hole 42 and is slidably mounted in the drive groove 33. In this way, when the first connecting post 212 is driven to slide by the drive platform 32, the first connecting post 212 slides along the drive groove 33, causing the first baffle plate 211 to slide. In addition, during the sliding process of the first connecting post 212, the first connecting post 212 can drive the transmission part 4 to rotate. The rotation of the transmission part 4 drives the second blocking block 22 to slide, so that the first blocking block 21 and the second blocking block 22 move closer to each other to close the through hole 11 or move further apart to open the through hole 11. Thus, the first blocking block 21 can drive the second blocking block 22 to slide through the transmission part 4, making the switch assembly 10 compact in structure.

[0066] In some embodiments, the first slot 42 is arranged in an arc shape. This arc-shaped first slot 42 allows for smoother movement of the first connecting post 212 passing through it, enabling the first connecting post 212 to stably drive the transmission unit 4 to rotate. Furthermore, compared to a straight slot, the arc-shaped slot provides a more uniform stress distribution when the first connecting post 212 moves, reducing localized stress concentration and thus lowering the risk of damage to the transmission unit 4 due to excessive stress, thereby improving the reliability and durability of the switch assembly 10.

[0067] It should be noted that in other embodiments, the first strip-shaped hole 42 can also be straight, or a combination of straight and arc shapes, etc. Specifically, this application does not limit it in this respect.

[0068] In some embodiments, the transmission part 4 is further provided with a second strip-shaped hole 43 along the axial direction of the through hole 11. The second strip-shaped hole 43 and the first strip-shaped hole 42 are located on opposite sides of the through hole 11 along the radial direction of the through hole 11. The shortest distance between the second strip-shaped hole 43 and the center line of the through hole 11 varies at different positions. The second blocking block 22 includes a second blocking plate 221 and a second connecting post 222. The second connecting post 222 protrudes from the second blocking plate 221 along the axial direction of the through hole 11. The end of the second connecting post 222 away from the second blocking block 22 is slidably installed in the second strip-shaped hole 43. Thus, when the transmission part 4 rotates, the second connecting post 222 slides in the second strip-shaped hole 43, allowing the second blocking plate 221 to slide closer to the first blocking plate 211 to close the through hole 11 or away from the first blocking plate 211 to open the through hole 11, thereby improving the accuracy of the opening and closing control of the through hole 11. The presence of the second strip-shaped hole 43 provides an independent motion guide channel for the second blocking block 22, allowing the second connecting post 222 to slide smoothly within the second strip-shaped hole 43 during the rotation of the transmission part 4. This prevents the second blocking block 22 from wobbling or shifting during movement, ensuring the stability of its movement. Simultaneously, its coordination with the movement of the first blocking block 21 makes the movement of the entire blocking part smoother, reducing noise and vibration caused by unstable movement and improving the user comfort of the switch assembly 10. The second strip-shaped hole 43 is symmetrically distributed along the axis of the through hole 11 on the transmission part 4, making full use of the space in the transmission part 4 and making the structure of the entire switch assembly 10 more compact. This compact design not only reduces the volume of the switch assembly 10, facilitating installation and use in limited spaces, but also reduces manufacturing costs and improves the product's market competitiveness. The second strip-shaped hole 43 and the first strip-shaped hole 42 are located on opposite sides of the through hole 11, avoiding interference between the first connecting post 212 and the second connecting post 222 during movement. This design allows the first blocking block 21 and the second blocking block 22 to move independently and smoothly, reducing malfunctions and damage caused by motion interference and improving the service life of the switch assembly 10.

[0069] Combination Figure 8 and Figure 9 , Figure 8 This is a cross-sectional schematic diagram of a switching assembly provided in an exemplary embodiment of this disclosure. Figure 9This is a schematic diagram of the base structure provided in an exemplary embodiment of this disclosure. In some embodiments, the second strip-shaped hole 43 is arranged in an arc shape. This makes the movement trajectory of the second connecting post 222 continuous and smooth, avoiding impacts and jerks caused by abrupt changes in shape, thereby ensuring that the rotation of the transmission part 4 can be smoothly converted into the sliding of the second connecting post 222, thus ensuring the smoothness of the movement of the second baffle 221 and reducing vibration and noise during movement. The arc-shaped second strip-shaped hole 43 helps to disperse the stress generated by the second connecting post 222 on the transmission part 4 during movement. Compared with a straight strip-shaped hole, the arc-shaped strip-shaped hole results in a more uniform stress distribution when the second connecting post 222 moves, reducing the phenomenon of local stress concentration, thereby reducing the risk of damage to the transmission part 4 due to excessive stress and improving the reliability and durability of the switch assembly 10 structure.

[0070] It should be noted that in other embodiments, the second strip-shaped hole 43 can also be straight, or a combination of straight and arc shapes, etc. Specifically, this application does not limit it in this respect.

[0071] Reference Figure 2 and Figure 8 In some embodiments, the blocking part is provided with a guide part 51, and the housing 1 is provided with a mating part 52. The guide part 51 and the mating part 52 are fitted together so that the blocking part can slide radially along the through hole 11. Thus, the fitted installation of the guide part 51 and the mating part 52 provides a precise guiding path for the blocking part, ensuring that it can only slide radially along the through hole 11. This precise guidance can effectively reduce the offset, wobbling, or tilting of the blocking part during sliding, ensuring that the blocking part can accurately reach the designated position, improving the stability and accuracy of the movement, thereby ensuring that the blocking part can accurately open or close the through hole 11.

[0072] It should be noted that the types of guide portion 51 and mating portion 52 can be selected as needed. For example, in one embodiment, guide portion 51 is configured as a protrusion, and correspondingly, mating portion 52 is configured as a guide groove extending radially along through hole 11. In another embodiment, guide portion 51 is configured as a guide hole, and correspondingly, mating portion 52 is configured as a guide rod extending radially along through hole 11. Specifically, this application does not limit the types of guide portion 51 and mating portion 52.

[0073] It should be noted that, in order to reduce the friction between the shielding part and the housing 1, in some embodiments, the coefficient of friction between the shielding part and the housing 1 can be reduced, for example, the surfaces of the shielding part and the housing 1 that contact each other can be made smooth, thereby reducing the friction. In other embodiments, the contact area between the shielding part and the housing 1 can also be reduced. Specifically, this application does not limit this.

[0074] Reference Figure 5 , Figure 6 and Figure 9 In some embodiments, one of the knob 31 and the housing 1 is provided with a rotation hole 61, and the other is provided with a rotation post 62 adapted to the rotation hole 61. Thus, the cooperation between the rotation hole 61 and the rotation post 62 provides stable support and positioning between the knob 31 and the housing 1. The rotation post 62, inserted into the rotation hole 61, restricts the knob 31's degrees of freedom in multiple directions, allowing it to rotate only around the axis of the rotation hole 61. This prevents the knob 31 from shaking, shifting, or falling off during operation, ensuring the stability and reliability of the entire switch assembly 10 structure. During the rotation of the knob 31, the contact surface between the rotation post 62 and the rotation hole 61 can disperse the stress generated by the rotational motion, reducing local stress concentration. This stress dispersion helps reduce the risk of component damage due to long-term stress, extends the service life of the knob 31 and the housing 1, and improves the durability of the switch assembly 10.

[0075] Reference Figure 5 and Figure 9 In some embodiments, a rotating hole 61 is provided in the knob 31, and a limiting groove 611 is provided on the inner wall of the rotating hole 61. The limiting groove 611 extends circumferentially along the rotating hole 61 and has two limiting surfaces 6111 spaced apart circumferentially along the rotating hole 61. The housing 1 is also provided with a limiting arm 12, which is slidably installed in the limiting groove 611. When the knob 31 is rotated, the limiting arm 12 is adapted to abut against one of the two limiting surfaces 6111. Thus, the cooperative design of the limiting groove 611 and the limiting arm 12 can precisely limit the rotation angle range of the knob 31. The limiting groove 611 extends circumferentially along the rotating hole 61 and has two spaced-apart limiting surfaces 6111. When the knob 31 rotates, the limiting arm 12 slides within the limiting groove 611. When it slides to abut against one of the limiting surfaces 6111, the knob 31 can no longer rotate in that direction, thus achieving effective control of the knob 31's rotation angle and meeting the needs of the knob 31's operating range in different application scenarios. When the limiting arm 12 abuts against the limiting surface 6111, the user can clearly feel the change in operating resistance, thus obtaining clear feedback on the rotation being in place. This clear feedback helps the user accurately judge the rotation state of the knob 31, avoiding over-rotation or under-rotation, improving the accuracy and reliability of operation, and also enhancing the user's confidence in operating the switch assembly 10.

[0076] It should be noted that the number of limiting slots 611 and limiting arms 12 can be selected as needed. This application does not limit this.

[0077] In some embodiments, the drive platform 32 is provided with a drive groove 33. Along the radial direction of the knob 31, the shortest distance between different positions of the drive groove 33 and the center line of the knob 31 varies. The blocking part includes a first blocking block 21 and a first connecting post 212. The first blocking block 21 has the first connecting post 212 protruding along the axial direction of the through hole 11. The first blocking block 21 is slidably mounted on the housing 1, and the first connecting post 212 is slidably mounted on the drive groove 33. Thus, when the knob 31 is rotated, the drive groove 33 pushes the first connecting post 212, thereby causing the first blocking block 21 to slide on the housing 1. Through this ingenious structural design, the position of the first blocking block 21 can be precisely adjusted according to the rotation of the knob 31, achieving dynamic control of the degree of blocking of the through hole 11 and meeting the needs of opening, closing, or partially blocking the through hole 11 in different application scenarios. The drive groove 33 determines the movement trajectory of the first connecting post 212, thereby precisely controlling the movement of the first blocking block 21. This indirect driving method based on the drive groove 33 avoids the instability and inaccuracy that may result from direct operation of the blocking block, ensuring that the first blocking block 21 slides along a predetermined trajectory and speed, thus improving the accuracy and reliability of the movement. The rotational motion of the knob 31 is converted into the linear sliding motion of the first blocking block 21 through the cooperation of the drive groove 33 and the first connecting post 212. This motion conversion process is smooth and continuous, reducing impact and vibration during the movement, making the movement of the first blocking block 21 more stable, and also reducing noise and wear caused by sudden changes in movement, thereby improving the overall performance and service life of the switch assembly 10. Using the drive groove 33 on the knob 31 to drive the movement of the first blocking block 21 eliminates the need for additional complex transmission mechanisms, greatly simplifying the structure of the switch assembly 10. This compact design allows the switch assembly 10 to achieve the required functions within a limited space, facilitating integration and installation in various devices, and improving the applicability and versatility of the product.

[0078] Reference Figure 2 and Figure 8 The housing 1 includes a base 13 and a cover 14, which are connected to form a cavity 15. The shielding part and the drive platform 32 are both located within the cavity 15. A through hole 11 extends through the base 13 and the cover 14. The cover 14 has an operation hole 141, with a portion of the knob 31 extending out of the operation hole 141. Thus, the base 13 and the cover 14, connected to form the cavity 15, provide a clear installation space for components such as the shielding part and the drive platform 32. The internal structure of the cavity 15 provides positioning and support for these components, ensuring they are installed and operated in the correct positions. Furthermore, the shielding part and the drive platform 32 being located within the cavity 15 protect them from external interference, ensuring stable functionality. The operation hole 141 on the cover 14 provides a channel for the extension of the knob 31, allowing the user to easily operate the knob 31 to control the shielding part.
