Description

Technical Field

[0001] This application belongs to the field of aerosol generation technology, and more specifically, relates to a dust cover structure and an aerosol generation device. Background Technology

[0002] An aerosol generating device is a device that heats and atomizes aerosol-generating products to produce aerosols. Aerosol generating devices generally have a heating chamber for inserting the aerosol-generating product, within which the product is heated. To prevent foreign objects from entering the heating chamber when not in use, a dust cover is typically installed at the top opening of the chamber. However, current dust cover designs have a large opening and closing stroke, occupying a significant amount of space, resulting in a large overall size of the aerosol generating device and hindering miniaturization design. Utility Model Content

[0003] The purpose of this application is to provide a dust cover structure and an aerosol generating device to solve the technical problem of large space occupation of the dust cover structure in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a dust cover structure is provided, including a fixed base, a movable component, and at least two cover bodies. The movable component is movably disposed on the fixed base, and each cover body is movably disposed on the fixed base, with each cover body connected to the movable component. The movable component can move from a first position to a second position, thereby driving each cover body from an open state to a closed state. In the open state, each cover body is at least partially separated from each other. In the closed state, each cover body converges to form a cover plate.

[0005] In some embodiments, the cover is rotatably mounted on the fixed base, and the opening angle of the cover from the open state to the closed state is α, 25° < α < 90°.

[0006] In some embodiments, the dust cover structure includes two cover bodies, which are rotatably disposed on the fixed base. When the movable member moves from the first position to the second position, it can drive the two cover bodies to rotate from the open state to the closed state.

[0007] In some embodiments, the cover has a mating groove, the movable member has a sliding portion, and the sliding portion is slidably disposed in the mating groove; when the movable member slides, it can drive the sliding portion to slide in the mating groove, so as to push the cover to rotate in the fixed seat.

[0008] In some embodiments, the dust cover structure further includes an elastic element connected to the fixed base, the elastic element being used to apply an elastic force to the movable element to hold the movable element in the first position and the second position.

[0009] In some embodiments, the fixed end of the elastic element is connected to the fixed base, and the movable end of the elastic element is connected to the movable element; when the movable element is located in the first position and the second position respectively, the movable ends of the elastic element are located on opposite sides of the fixed end of the elastic element along the movement direction of the movable element.

[0010] In some embodiments, the elastic member has a first limiting portion and a second limiting portion, and the movable member has a mating portion; when the movable member is in the first position, the mating portion engages with the first limiting portion to hold the movable member in the first position; when the movable member is in the second position, the mating portion engages with the second limiting portion to hold the movable member in the second position.

[0011] In some embodiments, the dust cover structure further includes a detection component for detecting the movement stroke of the movable part, and the detection component is communicatively connected to a host device.

[0012] In some embodiments, the fixing base has an insertion hole; when in the open state, each of the covers is at least partially separated to form an insertion space, the insertion space being directly opposite and communicating with the insertion hole; when in the closed state, each of the covers converges to block the insertion hole.

[0013] In some embodiments, the fixed base has a movable cavity, each of the covers is movably disposed in the movable cavity, the movable member is movably disposed in the movable cavity, and one end of the movable member extends outward from the fixed base; or, the movable member is connected to a drive cap located outside the fixed base.

[0014] On the other hand, this application also provides an aerosol generating apparatus, including an apparatus body and the aforementioned dust cover structure. The apparatus body has a heating chamber for accommodating the aerosol generating product, and the dust cover structure covers the top opening of the heating chamber.

[0015] The beneficial effects of the dust cover structure and aerosol generating device provided in this application are as follows: by splicing at least two cover bodies to form a cover plate, that is, dividing the cover plate into multiple cover bodies, the space occupied by the cover bodies is much smaller than the space occupied by the cover plate. Therefore, the range of motion of the cover body from the open state to the closed state is much smaller than the range of motion of the cover plate from the open state to the closed state. Moreover, each cover body moves from different directions to the closed state, that is, the movement space of each cover body is distributed in different directions, thereby reducing the overall space occupied by each cover body. At the same time, the movement of each cover body from the open state to the closed state is driven by the movement of the movable parts. The movement stroke of the movable parts is small and the space occupied is small, which makes the space occupied by the entire dust cover structure small, which is conducive to the miniaturization design of the aerosol generating device, or the miniaturization design of the device using the dust cover structure.

[0034] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0035] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0036] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, 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 application.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] As described in the background section, the current dust cover structure has a large opening and closing stroke, occupies a large space, and results in a large size of the entire aerosol generation device, which is not conducive to miniaturization design.

[0039] To solve the above-mentioned technical problems, this application provides a dust cover structure 1 and an aerosol generating device. By designing the structure of the dust cover structure 1, the dust cover structure 1 can achieve opening and closing action with a limited sliding stroke, thereby making the dust cover structure 1 occupy less space and facilitating the miniaturization design of the entire aerosol generating device.

[0040] Please see Figures 1 to 3 The aerosol generating apparatus provided in the embodiments of this application will now be described. The aerosol generating apparatus includes a main body 2 and a dust cover structure 1. The main body 2 has a heating chamber 21 for accommodating the aerosol generating product 3. The aerosol generating product 3 is heated in the heating chamber 21 to generate aerosol. The dust cover structure 1 covers the top opening of the heating chamber 21.

[0041] Please refer to the following: Figures 4 to 7The dust cover structure 1 provided in the embodiments of this application will now be described. This dust cover structure 1 is used in conjunction with the device body 2, which has a receiving cavity. The dust cover structure 1 is used to cover the opening of the receiving cavity. When the dust cover structure 1 is applied to an aerosol generating device, the device body 2 is the main part of the aerosol generating device used to heat and atomize the aerosol to generate the product 3, and the receiving cavity is the heating cavity 21. It can be understood that in other embodiments of this application, the dust cover structure 1 can also be applied to other devices with receiving cavities to prevent foreign objects from entering the receiving cavity, for example, it can be applied to storage boxes, cosmetic boxes, or electrical appliances.

[0042] The dust cover structure 1 includes a fixed base 100, a movable component 200, and at least two cover bodies 300. The movable component 200 is movably disposed on the fixed base 100, and each cover body 300 is movably disposed on the fixed base 100. Each cover body 300 is connected to the movable component 200. The movable component 200 can slide from a first position to a second position to drive each cover body 300 from an open state to a closed state. In the open state, each cover body 300 is at least partially separated from each other. In the closed state, each cover body 300 converges to form a cover plate.

[0043] The number of covers 300 can be determined according to actual design requirements. For example, it can be two, three, four or more. Generally, two to four are selected. The more covers 300 there are, the more complex the driving structure of the moving part 200 to the covers 300 becomes.

[0044] The cover 300 is movably disposed on the fixed base 100. For example, the cover 300 can be rotatably disposed on the fixed base 100, and the movable member 200 drives each cover 300 to rotate to at least partially separate from each other, or drives each cover 300 to rotate to move closer to each other; or, the cover 300 can be slidably disposed on the fixed base 100, and the movable member 200 drives each cover 300 to move to at least partially separate from each other, or drives each cover 300 to move to move closer to each other; in some embodiments, the movable member 200 is a movable member; in addition, the cover 300 in the fixed base 100 can also perform a combination of sliding and rotational movements.

[0045] The movable component 200 is slidable or rotatable on the fixed base 100. Taking the movable component 200 as a sliding component as an example, Figure 3 As shown, the movable part 200 is in the first position. Figure 4 When the movable part 200 is in the second position, when the movable part 200 slides from the first position to the second position, the covers 300 come together to form a cover plate, thereby achieving the covering effect.

[0046] When this dust cover structure 1 is applied in an aerosol generating device, please refer to [link / reference needed]. Figure 1 , Figure 3 and Figure 4 In the open state, each cover 300 is at least partially separated from each other to form an insertion space 330 between the covers 300, thereby facilitating the insertion of the aerosol-generated article 3 into the heating chamber 21 via the insertion space 330; see also Figure 2 and Figure 5 When closed, the covers 300 come together to form a whole cover plate. The cover plate closes to seal the top opening of the heating chamber 21, thereby preventing foreign objects from entering the heating chamber 21.

[0047] The dust cover structure 1 in this embodiment is formed by splicing at least two cover bodies 300 to form a cover plate, that is, the cover plate is divided into multiple cover bodies 300. The space occupied by each cover body 300 is much smaller than the space occupied by the cover plate. Therefore, the range of motion of each cover body 300 from the open state to the closed state is much smaller than the range of motion of the cover plate from the open state to the closed state. Moreover, each cover body 300 moves to the closed state from different directions, that is, the movement space of each cover body 300 is distributed in different directions, thereby reducing the overall space occupied by each cover body 300. At the same time, the movement of each cover body 300 from the open state to the closed state is driven by the movement of the movable part 200. The movement stroke of the movable part 200 is small and the space occupied is small, which makes the entire dust cover structure 1 occupy a small space, which is conducive to the miniaturization design of the aerosol generation device.

[0048] In some embodiments, please refer to Figures 1 to 3 The aerosol generating device also has a mounting cavity, with the movable part 200 slidably mounted on the fixed base 100. The mounting cavity and the heating cavity 21 are spaced apart along the sliding direction of the movable part 200. The mounting cavity is used to mount the atomizer 4, and the aerosol generating device is also used to supply power to the atomizer 4. After being powered on, the atomizer 4 can heat and atomize the liquid matrix stored inside to generate a first aerosol. The first aerosol enters the aerosol generating product 3 to mix with the second aerosol generated by heating the aerosol generating product 3. In this embodiment, the dust cover structure 1 can also be applied to an aerosol generating device that atomizes and mixes liquid and solid matrices. Since the sliding stroke of the dust cover structure 1 along the sliding direction of the movable part 200 is small, it will not occupy the space of the atomizer 4 and will not affect the disassembly and use of the atomizer 4.

[0049] In some embodiments, please refer to Figures 3 to 9The fixing base 100 has an insertion hole 101. When in the open state, each cover 300 is at least partially separated to form an insertion space 330, which is directly connected to the insertion hole 101, thereby facilitating the insertion of the aerosol-generated product 3 into the heating chamber 21 via the insertion space 330 and the insertion hole 101. When in the closed state, each cover 300 converges to form a single cover plate, which blocks the insertion hole 101, thereby sealing the top opening of the heating chamber 21 and preventing foreign objects from entering the heating chamber 21. It is understood that in other embodiments, when the dust cover structure 1 is applied to other devices, items can also be added to the receiving cavity in the above manner.

[0050] In some embodiments, please refer to Figure 3 The insertion hole 101 extends longitudinally through the fixing base 100 and is positioned directly opposite the receiving cavity. Here, longitudinal refers to the distribution direction of the dust cover structure 1 and the receiving cavity (e.g., heating cavity 21), so that the insertion hole 101 and the receiving cavity are directly opposite each other.

[0051] In some embodiments, please refer to Figures 7 to 9 The dust cover structure 1 includes two cover bodies 300, each rotatably mounted on a fixed base 100. When the movable member 200 moves from a first position to a second position, it can drive the two cover bodies 300 to rotate from an open state to a closed state. By converting the movement of the movable member 200 into the rotation of the cover bodies 300, the space occupied by the movable member 200 and the cover bodies 300 along the movement direction can be reduced. Simultaneously, the space occupied by the movable member 200 and the cover bodies 300 along the opening direction can also be reduced, resulting in a compact structural layout and a small overall space footprint. Furthermore, the arrangement of two cover bodies 300 simplifies the driving of the cover bodies 300 by the movable member 200 while reducing the space occupied by the dust cover structure 1, eliminating the need for a transmission component between the movable member 200 and the cover bodies 300. Understandably, in other embodiments of this application, when the cover 300 is rotatably mounted on the fixed base 100, there may be three or four covers 300. In this case, the movable member 200 and the cover 300 can be connected by a transmission member. In addition, in other embodiments, the movement of the movable member 200 can also drive two or more covers 300 to slide in different directions to move closer to or further away from each other. This is not a unique limitation.

[0052] In some embodiments, please refer to Figures 7 to 9 The movable part 200 is configured to slide along the first direction X on the fixed base 100. The movable part 200 has a first center line O1 along the second direction Y. The two covers 300 are spaced apart along the second direction Y and are symmetrically arranged on opposite sides of the first center line O1.

[0053] Wherein, the first direction X and the second direction Y are perpendicular, and both the first direction X and the second direction Y are perpendicular to the longitudinal direction of the dust cover structure 1. The longitudinal direction of the dust cover structure 1 refers to the direction of extension that extends perpendicularly from the side of the dust cover structure 1 toward the receiving cavity to the side away from the receiving cavity.

[0054] When the movable part 200 slides from the first position to the second position along the first direction X, it can drive the two covers 300 to rotate from the open state to the closed state along the second direction Y. This arrangement allows the movable part 200 and the two covers 300 to move along the first direction X and the second direction Y respectively, so that the layout of the movable part 200 and the two covers 300 is compact and the overall space occupied is small.

[0055] In the above embodiment, as the movable member 200 slides from the first position to the second position along the first direction X, the distance between the movable member 200 and the insertion hole 101 gradually decreases. That is, when the movable member 200 slides closer to the insertion hole 101, it can drive the two covers 300 to rotate toward the insertion hole 101 to close at the insertion hole 101. When the movable member 200 slides away from the insertion hole 101, it can drive the two covers 300 to rotate away from the insertion hole 101 to avoid the insertion hole 101.

[0056] In some embodiments, the cover 300 is rotatably mounted on the fixed base 100, and the opening angle of the cover 300 from the open state to the closed state is α, 25° < α < 90°. For example, the opening angle of the cover 300 can be 26°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, or 89°, etc. The opening angle of the cover 300 cannot be too small. If it is too small, the sliding stroke of the moving part 200 will be too large, or the insertion space 330 formed when each cover 300 is opened will be too small, making it impossible to completely avoid the insertion hole 101, resulting in the aerosol-generated product 3 being unable to be inserted into the heating chamber 21. Furthermore, if the opening angle of the cover 300 is too large, it will easily cause jamming during the opening and closing process, resulting in uneven opening and closing.

[0057] For some specific embodiments, please refer to Figures 7 to 9 The dust cover structure 1 includes two cover bodies 300, which are rotatably mounted on the fixed base 100. The opening and closing angle of the cover body 300 is 30°. At this time, the sliding stroke of the movable part 200 is 4mm. Compared with the sliding stroke of 10mm-20mm of sliding covers on the market, this embodiment can greatly reduce the sliding stroke of the movable part 200 and reduce the space occupied.

[0058] In some embodiments, please refer to Figure 8 and Figure 9The cover 300 has an inner splicing surface 310 and an outer splicing surface 320. In the closed state, the inner splicing surfaces 310 of each cover 300 are fitted together, and the outer splicing surfaces 320 of each cover 300 are combined to form a cylindrical surface. The above arrangement ensures that when each cover 300 is closed, the cover plate formed by each cover 300 is at least partially circular to cover the insertion hole 101.

[0059] Optionally, the outer diameter of the circumferential surface formed by the combination of the outer splicing surfaces 320 of each cover 300 is greater than or equal to the inner diameter of the insertion hole 101, thus ensuring the cover's ability to block the insertion hole 101. In practical applications, the outer diameter of the circumferential surface formed by the combination of the outer splicing surfaces 320 of each cover 300 is slightly larger than the inner diameter of the insertion hole 101, so that each cover 300, while effectively blocking the insertion hole 101, is not too large in size and occupies too much space.

[0060] For some specific embodiments, please refer to Figure 8 and Figure 9 The dust cover structure 1 includes two cover bodies 300, which are rotatably mounted on the fixed base 100. The inner splicing surface 310 of the cover body 300 is a plane, and the outer splicing surface 320 of the cover body 300 is approximately an outer semi-cylindrical surface. When the two cover bodies 300 are closed, the inner splicing surfaces 310 of the two cover bodies 300 abut against each other, and the outer splicing surfaces 320 of the two cover bodies 300 are spliced ​​into a cylindrical surface.

[0061] In the above embodiments, please refer to Figure 2 The cover 300 includes a connecting part 360 and a closing part 370. The closing part 370 is semi-circular. The inner splicing surface 310 and the outer splicing surface 320 are the two surfaces of the closing part 370, respectively. The connecting part 360 is connected to the outer splicing surface 320 of the closing part 370. The connecting part 360 is rotatably connected to the fixed base 100, and the connecting part 360 is connected to the movable part 200.

[0062] In some embodiments, please refer to Figures 7 to 10 The cover 300 has a mating groove 340, and the movable member 200 has a sliding part 220, which is slidably disposed in the mating groove 340. When the movable member 200 slides, it can drive the sliding part 220 to slide in the mating groove 340, thereby pushing the cover 300 to rotate in the fixed base 100. Since the cover 300 is rotatably disposed in the fixed base 100, when the sliding part 220 slides to push the cover 300, the cover 300 is driven to rotate.

[0063] Specifically, the cover 300 has a pivot point, and the mating groove 340 is located outside the pivot point. When the sliding part 220 slides in the mating groove 340, it can push the wall of the mating groove 340 so that the cover 300 rotates around the pivot point.

[0064] Specifically, the mating groove 340 has a first end 343 and a second end 344 disposed opposite to each other, and the mating groove 340 has a first wall surface 341 and a second wall surface 342 disposed opposite to each other between the first end 343 and the second end 344. The first wall surface 341 of the two covers 300 is located outside the second wall surface 342 of the two covers 300. When the movable member 200 is in the first position, the sliding part 220 is located at the first end 343 of the mating groove 340. When the movable member 200 slides from the first position to the second position, the sliding part 220 slides from the first end 343 to the second end 344, and the sliding part 220 pushes the first wall surface 341 in the direction of the first center line O1, so that the covers 300 rotate in the direction of the first center line O1, so that the two covers 300 close together. When the movable part 200 slides from the second position to the first position, the sliding part 220 slides from the second end 344 to the first end 343. The sliding part 220 pushes the second wall surface 342 away from the first center line O1, so that the two covers 300 rotate away from the first center line O1, so that the two covers 300 open.

[0065] In some embodiments, please refer to Figure 8 and Figure 9 The mating groove 340 is located on the side of the rotation fulcrum facing the first center line O1.

[0066] In some embodiments, please refer to Figure 8 and Figure 9 During the process of the movable part 200 sliding from the open state to the closed state, the first wall surface 341 and the second wall surface 342 are both at an angle to the first center line O1, so that the sliding part 220 can push the first wall surface 341 and the second wall surface 342 to rotate when sliding along the first direction X.

[0067] For some specific embodiments, please refer to Figure 11 The movable component 200 includes a sliding body 210 and a sliding part 220 protruding from the sliding body 210 toward the cover 300. The sliding body 210 is slidably disposed on the fixed base 100, and the sliding part 220 is slidably disposed in the mating groove 340.

[0068] For some specific embodiments, please refer to Figure 7 and Figure 10 The cover 300 has a rotating hole 350, and the fixed base 100 has a rotating post 111. The rotating hole 350 is rotatably fitted onto the rotating post 111, thereby allowing the cover 300 to rotate within the fixed base 100. It is understood that in other embodiments of this application, the rotating post 111 may also be located on the cover 300, and the rotating hole 350 may be located on the fixed base 100; this is not a unique limitation.

[0069] For some specific embodiments, please refer to Figure 4 and Figure 11 The movable part 200 also includes a guide part 230, and the fixed base 100 also has a guide groove 103. The guide part 230 is slidably disposed in the guide groove 103 to guide the sliding of the movable part 200 along the first direction X.

[0070] In some embodiments, please refer to Figure 12 and Figure 13 The dust cover structure 1 also includes an elastic element 400, which is connected to the fixed base 100. The elastic element 400 applies an elastic force to the movable element 200 to hold the movable element 200 in a first position and a second position. Specifically, when the movable element 200 is in the first position, the elastic element 400 applies a first elastic force to the movable element 200 to hold it in the first position. At this time, an external force is needed to push the movable element 200 to overcome the first elastic force, so that the movable element 200 slides from the first position to the second position. When the movable element 200 is in the second position, the elastic element 400 applies a second elastic force to the movable element 200 to hold it in the second position. At this time, an external force is needed to push the movable element 200 to overcome the second elastic force, so that the movable element 200 slides from the second position to the first position.

[0071] In this application, the connection method of the elastic element 400 can be in several ways.

[0072] For example, in some of these embodiments, please refer to Figure 12 and Figure 13 The fixed end 410 of the elastic element 400 is connected to the fixed base 100, and the movable end 420 of the elastic element 400 is connected to the movable element 200. When the movable element 200 is in the first position and the second position respectively, the movable end 420 of the elastic element 400 is respectively located on the opposite sides of the fixed end 410 of the elastic element 400 along the movement direction of the movable element 200.

[0073] For details, please refer to Figure 12 When the movable member 200 is in the first position, the movable end 420 of the elastic member 400 is located on the side of the fixed end 410 of the elastic member 400 away from the insertion hole 101 along the first direction X, so that the elastic member 400 has a first elastic force on the movable member 200 to prevent the movable member 200 from sliding in the direction of the insertion hole 101, so that the movable member 200 is kept in the first position.

[0074] Please see Figure 13 When the movable member 200 is in the second position, the movable end 420 of the elastic member 400 is located on the side of the fixed end 410 of the elastic member 400 facing the insertion hole 101 in the first direction X, so that the elastic member 400 has a second elastic force on the movable member 200 to prevent the movable member 200 from sliding away from the insertion hole 101, so that the movable member 200 is kept in the second position.

[0075] Optionally, the elastic element 400 is a torsion spring, with its middle portion wound in a circular shape. The fixed end 410 and the movable end 420 of the torsion spring are connected to the fixed base 100 and the movable element 200, respectively. The tension and thrust of the torsion spring are used to hold and push the movable element 200. It is understood that in other embodiments of this application, the elastic element 400 may also be a tension spring.

[0076] In some embodiments, please refer to Figure 7 The fixed base 100 is provided with a first mounting post 112, the movable part 200 is provided with a second mounting post 240, the fixed end 410 of the elastic part 400 is fixedly sleeved on the first mounting post 112, and the movable end 420 of the elastic part 400 is fixedly sleeved on the second mounting post 240.

[0077] Please see Figure 14 and Figure 15 In some other embodiments of this application, the elastic member 400 is formed with a first limiting portion 430 and a second limiting portion 440, and the movable member 200 is formed with a mating portion 250; when the movable member 200 is in the first position, the mating portion 250 engages with the first limiting portion 430 to hold the movable member 200 in the first position; when the movable member 200 is in the second position, the mating portion 250 engages with the second limiting portion 440 to hold the movable member 200 in the second position.

[0078] Optionally, the first limiting portion 430 and the second limiting portion 440 are limiting protrusions, and the mating portion 250 is a limiting groove. Alternatively, in other embodiments, the first limiting portion 430 and the second limiting portion 440 are limiting grooves, and the mating portion 250 is a limiting protrusion; this is not a unique limitation.

[0079] Optionally, the elastic element 400 is a spring-loaded spring or a sheet spring.

[0080] In some embodiments, please refer to Figure 6 The dust cover structure 1 also includes a detection component 500, which detects the sliding stroke of the movable part 200. The detection component 500 is communicatively connected to a host device. The host device can be an aerosol generating device or other devices. In this embodiment, the detection component 500 detects the sliding stroke of the movable part 200 to determine whether the dust cover structure 1 is in an open or closed state. For example, when the dust cover structure 1 is in the open state, the aerosol generating product 3 can be inserted into the heating chamber 21.

[0081] In some specific embodiments, the detection component 500 includes a detection element and a test element 510. The detection element is installed on the fixed base 100, and the test element 510 is installed on the movable element 200. When the movable element 200 slides, it drives the test element 510 to slide. The detection element determines the position of the movable element 200 by detecting the position of the test element 510, thereby determining whether the dust cover structure 1 is in an open or closed state.

[0082] Optionally, the tested component 510 is a magnetic component, and the detection component is a Hall switch. The magnetic component can generate magnetism around itself. When the magnetic component moves, the magnetic field strength around it changes. The Hall switch detects these changes and converts them into an electrical signal output. By analyzing these electrical signals, the displacement of the magnetic component can be determined, thereby determining the displacement of the movable component 200. It is understood that in other embodiments of this application, the detection component 500 can also detect the travel of the movable component 200 in other ways, such as with an optical sensor.

[0083] In some embodiments, please refer to Figure 4 The fixed base 100 has a movable cavity 102, in which each cover 300 is movably disposed. A movable component 200 is slidably disposed in the movable cavity 102, and the movable component 200 is connected to a drive cap 600. The drive cap 600 is located outside the fixed base 100, allowing the user to drive the movable component 200 to slide by holding the drive cap 600. The movable cavity 102 conceals each cover 300 and part of the movable component 200, protecting them and maintaining the aesthetic appearance of the entire dust cover structure 1. Simultaneously, the drive cap 600 allows the user to drive the movable component 200 to slide from outside the fixed base 100. It is understood that in other embodiments of this application, the drive cap 600 may be omitted, and one end of the movable component 200 may extend outward from the fixed base 100 for user actuation; this is not a limiting factor.

[0084] In some embodiments, please refer to Figure 6 The fixing base 100 includes a first fixing member 110 and a second fixing member 120, which overlap each other to form a movable cavity 102. Specifically, the first fixing member 110 and the second fixing member 120 are interlocked and locked by fasteners.

[0085] Specifically, the insertion hole 101 passes through the first fixing member 110 and the second fixing member 120.

[0086] Specifically, the movable component 200 includes a sliding body 210 and sliding portions 220 protruding from opposite sides of the sliding body 210. The first fixing member 110 and the second fixing member 120 are provided with guide grooves 103 corresponding to the positions of the two sliding portions 220. In this way, the sliding of the movable component 200 can be guided by the two guide grooves 103 respectively, so as to ensure the smooth sliding of the movable component 200.

[0087] Specifically, the guide groove 103 is connected to the insertion hole 101, so that the movable part 200 can be partially slid to a position directly opposite the longitudinal direction of the insertion hole 101, so as to make the structural layout more compact.

[0088] Specifically, the cover 300 and the elastic element 400 are respectively located on opposite sides of the sliding body 210 to reduce structural interference between the cover 300 and the elastic element 400.

[0089] In some embodiments, the side wall of the fixing seat 100 has an avoidance groove corresponding to the position where the cover 300 is in the open state, so as to avoid structural interference between the cover 300 and the inner wall of the fixing seat 100 when the cover 300 is rotated open, thereby reducing the space occupied by the entire dust cover structure 1.

[0090] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
