Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a cleaning device. Background Technology

[0002] Cleaning robots are typically equipped with a mop, which wipes and cleans surfaces to remove dust, stains, and dirt. When cleaning corners, edges, or obstacles, the mop can swing outwards through openings in the casing to clean these areas. However, these openings allow debris (such as dust, hair, wastewater, fruit peels, or paper scraps) to enter the robot, potentially contaminating its internal components.

[0003] Currently, existing technology uses a cover at the opening to prevent debris from entering the cleaning robot. However, when the mop is cleaning in the outward-expanding area, the cover is easily damaged by low, suspended obstacles, and may even cause problems such as obstruction of the mop's movement and jamming or damage to other components inside the cleaning robot. Utility Model Content

[0004] The main objective of this application is to provide a cleaning device that solves the problem mentioned in the background art where the cover plate is easily damaged by low, suspended obstacles when the mop is cleaning in the outward position.

[0005] According to one aspect of this application, a cleaning device is provided, comprising:

[0006] A housing, wherein an opening is provided on the outer peripheral sidewall of the housing;

[0007] A cleaning component having an inwardly recessed position near the housing and an outwardly extended position beyond the outer edge of the housing, wherein, in the projection of the cleaning component in the height direction of the cleaning device, the area of ​​the cleaning component extending beyond the outer edge of the housing when it is in the outwardly extended position is greater than the area of ​​the cleaning component extending beyond the outer edge of the housing when it is in the inwardly recessed position;

[0008] A shielding assembly connected to the housing, the shielding assembly having a first state of covering the opening, and a second state of opening at least a portion of the opening;

[0009] During the process of the cleaning component moving from the inward and outward position to the outward position, the shielding component is driven to change from the first state to the second state. When the cleaning component moves to the inward position, the shielding component changes from the second state to the first state.

[0010] The shielding component is at least partially deformed by an external force and recovers its deformation after the external force is removed.

[0011] Furthermore, the occlusion component includes:

[0012] A first cover plate component and a second cover plate component are arranged circumferentially along the housing. The ends of the first cover plate component and the second cover plate component away from each other are respectively connected to the housing. When the shielding assembly is in the first state, the first cover plate component and the second cover plate component together cover the opening.

[0013] During the transition of the cleaning component from the retracted position to the expanded position, the cleaning component applies a force to at least one of the first cover plate component and the second cover plate component to open at least a portion of the opening.

[0014] Furthermore, the first cover plate component is a first flexible cover, and the second cover plate component is a second flexible cover. During the movement of the cleaning component from the inward position to the outward position, the cleaning component applies a force to at least one of the first flexible cover and the second flexible cover to deform the first flexible cover and / or the second flexible cover and at least partially open the opening.

[0015] When the cleaning component moves to the retracted position, the first flexible cover and / or the second flexible cover restore their deformation and together cover the opening.

[0016] Furthermore, the first flexible cover and / or the second flexible cover are provided with a first deformation reinforcement portion.

[0017] Furthermore, the first deformation reinforcement includes a first groove. The first groove on the first flexible cover is disposed on the side of the first flexible cover near the housing and extends along the height direction of the housing and penetrates the first flexible cover. The first groove on the second flexible cover is disposed on the side of the second flexible cover near the housing and extends along the height direction of the housing and penetrates the second flexible cover. The opening of the first groove faces the outside of the housing.

[0018] Furthermore, the first cover plate component includes a first hard cover, and the second cover plate component includes a second hard cover. The first hard cover and the second hard cover are respectively connected to the housing. An elastic member is provided on the outer edge of at least one of the first hard cover and the second hard cover. The elastic member deforms under the action of an external force and recovers its deformation after the external force is removed. When the shielding component is in the first state, the elastic member, the first hard cover and the second hard cover together cover the opening.

[0019] Furthermore, along the circumference of the housing, the first hard cover and the second hard cover are arranged at intervals, and the sides of the first hard cover and the second hard cover away from each other are respectively rotatably connected to the housing. The elastic member includes an elastic cover, which is disposed on the side of at least one of the first hard cover and the second hard cover away from the cleaning component and extends to the outer edge of the corresponding first hard cover and / or the outer edge of the second hard cover.

[0020] Furthermore, the elastic cover is provided with a snap-fit ​​groove, and the first hard cover and / or the second hard cover are at least partially embedded in the snap-fit ​​groove and are interference-fitted with the inner wall surface of the snap-fit ​​groove.

[0021] Furthermore, the elastic cover is connected to the first hard cover. When the shielding component is in the first state, the elastic cover covers one side of the opening, and the second hard cover covers the other side of the opening and abuts against the elastic cover. Along the circumference of the housing, the length of the elastic cover is greater than the length of the second hard cover.

[0022] Furthermore, the elastic member is at least partially disposed at the top of the first hard cover and / or the second hard cover along the height direction of the housing and protrudes outside the edge of the first hard cover and / or the second hard cover.

[0023] Furthermore, the elastic member is at least partially disposed at the end of the first hard cover and / or the second hard cover away from the housing in the longitudinal direction and protrudes outside the edge of the first hard cover and / or the second hard cover.

[0024] Furthermore, the elastic component is provided with a second deformation reinforcement portion, which is offset between the first hard cover and the second hard cover.

[0025] Furthermore, the second deformation reinforcement includes at least one of a strip groove, a blind hole, and a through hole.

[0026] Furthermore, the strip groove is disposed on the side of the elastic member near the cleaning component, and the length of the strip groove extends along the height direction of the housing and passes through the elastic member.

[0027] Furthermore, the cleaning equipment also includes a position adjustment assembly, the position adjustment assembly comprising:

[0028] A rotating connecting component is disposed on the housing, and the first hard cover and the second hard cover are respectively rotatably connected to the housing via the rotating connecting component;

[0029] A reset component is installed between the housing and the first hard cover and / or between the housing and the second hard cover. The reset component can reciprocate between a first form and a second form. During the process of the blocking component transitioning from the first state to the second state, the reset component is driven to deform from the first form to the second form. During the process of the blocking component transitioning to the first state, the reset component has a tendency to deform from the second form to the first form to drive the first hard cover and / or the second hard cover back to the first form.

[0030] Furthermore, the cleaning assembly includes a drive mechanism and a cleaning component connected to the drive mechanism. The drive mechanism is installed inside the housing and can swing relative to the housing to allow the cleaning assembly to switch between the retracted position and the expanded position. The cleaning component switches between the retracted position and the expanded position around a swing center. The second cover plate component is disposed close to the swing center. Along the circumference of the housing, the length of the first cover plate component is greater than the length of the second cover plate component.

[0031] In this application, when the cleaning component cleans blind spots such as corners, edges, and obstacles, it can move to an expanded position through an opening in the housing to clean these blind spots, thus improving the cleaning capability of the cleaning equipment. When the cleaning component is cleaning in the expanded position, low, suspended obstacles may hinder the movement of the cleaning equipment. In this case, the blocking component will deform under the force of the obstacle to avoid it, effectively reducing the risk of the blocking component being jammed and damaged by the obstacle. This also effectively prevents the movement of the cleaning component from being obstructed and other components inside the cleaning equipment from being jammed and damaged, thus helping to extend the service life of the cleaning equipment.

[0053] Example 1:

[0054] like Figures 1 to 6As shown, this application provides a cleaning device. The cleaning device includes a housing 10, a cleaning component 20, and a shielding component 30. An opening 11 is provided on the outer peripheral sidewall of the housing 10. The cleaning component 20 has an inwardly recessed position near the housing 10 and an outwardly expanding position extending beyond the outer edge of the housing 10. In the height direction of the cleaning device (e.g., ...) Figure 1 Within the projection of the direction indicated by the middle arrow X, the area of ​​the cleaning component 20 extending beyond the outer edge of the housing 10 when it is in the outward position is greater than the area of ​​the cleaning component 20 extending beyond the outer edge of the housing 10 when it is in the inward position. The shielding component 30 is connected to the housing 10 and has a first state covering the opening 11, and a second state where at least a portion of the opening 11 is open. During the movement of the cleaning component 20 from the inward to the outward position, the shielding component 30 is converted from the first state to the second state; when the cleaning component 20 moves to the inward position, the shielding component 30 converts from the second state back to the first state. The shielding component 30 is at least partially deformed by an external force and recovers its deformation after the external force is removed.

[0055] In this embodiment, when the cleaning component 20 cleans blind spots such as corners, edges, and obstacles, it can move to an expanded position through the opening 11 on the housing 10 to clean these blind spots, thus improving the cleaning capability of the cleaning equipment. When the cleaning component 20 is cleaning in the expanded position, low, suspended obstacles may hinder the movement of the cleaning equipment. At this time, the blocking component 30 will deform under the force of the obstacle to avoid it, effectively reducing the risk of the blocking component 30 being jammed and damaged by the obstacle. This effectively prevents the movement of the cleaning component 20 from being obstructed and other components inside the cleaning equipment from being jammed and damaged, thus extending the service life of the cleaning equipment.

[0056] As the cleaning component 20 moves from the retracted position to the outward expansion position, it applies a force to the blocking component 30, causing the blocking component 30 to transition from a first state to a second state, thereby opening at least a portion of the opening 11. The cleaning component 20 can then move to the outside edge of the housing 10 through the opened portion of the opening 11. When the cleaning component 20 moves from the outward expansion position to the retracted position, the force applied by the cleaning component 20 to the blocking component 30 is removed, and the blocking component 30 automatically returns to its original position, closing the opening 11. This ensures that debris does not enter the housing 10 through the opening 11, effectively protecting other components inside the housing 10 from contamination.

[0057] Secondly, the shielding component 30 not only improves the overall aesthetic design of the cleaning equipment (which is especially important for cleaning equipment that pursues a minimalist design), but also prevents users' fingers or pets' tails, limbs, etc. from entering the housing 10 through the opening 11 and causing accidental injury, thereby improving the safety of using the cleaning equipment.

[0058] Understandably, when the cleaning component 20 is in the retracted position, it can be entirely located inside the housing 10 without protruding from the edge of the housing 10, or it can be partially located at the edge of the housing 10. When the cleaning component 20 is in the outward-expanding position, the area of ​​the cleaning component 20 protruding from the edge of the housing 10 is larger than the area of ​​the cleaning component 20 protruding from the edge of the housing 10 when it is in the retracted position. The cleaning component 20 can reach hard-to-reach blind spots such as corners and edges of walls, ensuring a wider cleaning range and a more thorough cleaning effect.

[0059] In one embodiment, the shielding assembly 30 includes a first cover plate component and a second cover plate component. The first cover plate component and the second cover plate component are circumferentially aligned with the housing 10 (e.g., along the circumference of the housing 10). Figure 1 Arranged in the direction indicated by the middle arrow Y). The ends of the first and second cover components, away from each other, are respectively connected to the housing 10. When the shielding assembly 30 is in the first state, the first and second cover components together cover the opening 11. During the process of the cleaning assembly 20 changing from the retracted position to the outward expansion position, the cleaning assembly 20 applies a force to at least one of the first and second cover components to open at least part of the opening 11. When the cleaning assembly 20 is in the retracted position and the shielding assembly 30 is in the first state, the first cover component covers one side of the opening 11, and the second cover component covers the other side of the opening 11 and is disposed adjacent to the first cover component. The first and second cover components constitute a double-door structure that can cover and shield the opening 11, ensuring that all parts of the opening 11 are shielded and covered. During the transition of the cleaning assembly 20 from the retracted position to the expanded position, the cleaning assembly 20 applies force to the first and second cover plate components, causing them to transition from a first state to a second state, thereby opening at least a portion of the opening 11. At this time, a gap is created between the first and second cover plate components, opening at least a portion of the opening 11, through which the cleaning assembly 20 can transition between the retracted and expanded positions. Understandably, during the transition from the retracted to the expanded position, the cleaning assembly 20 can apply force independently to either the first or second cover plate component, causing either component to open at least a portion of the opening 11 accordingly. When the cleaning assembly 20 is performing cleaning operations in the expanded position, if at least one of the first and second cover plate components is obstructed by a low, suspended obstacle, at least a portion of the first and second cover plate components can deform to avoid the obstacle, effectively reducing the risk of damage to the first and second cover plate components and extending the service life of the cleaning equipment.

[0060] In another embodiment, the first cover plate component and the second cover plate component may also be disposed on the cleaning assembly 20. In another embodiment, the cleaning assembly 20 includes a drive mechanism 21 and a cleaning component 22 connected to the drive mechanism 21. The drive mechanism 21 is mounted inside the housing 10 and is rotatable relative to the housing 10 to switch the cleaning assembly 20 between an inward position and an outward position. The first cover plate component and the second cover plate component may also be disposed on the drive mechanism 21. The drive mechanism 21 moves to cause the first cover plate component and / or the second cover plate component to open the opening 11 at least partially.

[0061] Understandably, the first cover plate component and the second cover plate component can also be arranged in a direction inclined to the circumference of the housing 10 and form a double door structure.

[0062] Among them, such as Figures 3 to 6 As shown, the first cover component is a first flexible cover 31. The second cover component is a second flexible cover 32. During the movement of the cleaning assembly 20 from the retracted position to the outward expansion position, the cleaning assembly 20 applies a force solely to the first flexible cover 31, causing it to deform and at least partially open the opening 11. Alternatively, the cleaning assembly 20 applies a force solely to the second flexible cover 32, causing it to deform and at least partially open the opening 11. Alternatively, the cleaning assembly 20 applies a force to both the first and second flexible covers 31 and 32, causing both to deform and at least partially open the opening 11. When the cleaning assembly 20 moves to the retracted position, the first and second flexible covers 31 and 32 together cover at least a portion of the opening 11. Alternatively, when the cleaning assembly 20 moves to the retracted position, the first and second flexible covers 31 and 32 completely cover the opening 11. When the cleaning component 20 is in the retracted position, the shielding component 30 is in the first state, with the first flexible cover 31 covering one side of the opening 11 and the second flexible cover 32 covering the other side of the opening 11. The first flexible cover 31 and the second flexible cover 32 form a double-door structure that can cover and shield the opening 11, ensuring that all parts of the opening 11 are shielded and covered.

[0063] In one embodiment, a first deformation reinforcing portion 33 is provided on the first flexible cover 31. Alternatively, a first deformation reinforcing portion 33 is provided on the second flexible cover 32. Alternatively, both the first flexible cover 31 and the second flexible cover 32 are provided with the first deformation reinforcing portion 33. The first deformation reinforcing portion 33 can improve the deformation capability. By pre-setting a thinner area on at least one of the first flexible cover 31 and the second flexible cover 32, the first flexible cover 31 and the second flexible cover 32 will preferentially deform in a predetermined direction when subjected to force, ensuring that the first flexible cover 31 and the second flexible cover 32 deform in a direction away from the cleaning component 20 after being pushed by the cleaning component 20, so as to achieve more accurate opening of the opening 11 in the predetermined direction. When the first flexible cover 31 and the second flexible cover 32 are subjected to the force applied by an obstacle, the first flexible cover 31 and the second flexible cover 32 can deform more quickly to avoid or detach from the obstacle, effectively preventing the first flexible cover 31 and the second flexible cover 32 from being jammed or damaged by the obstacle.

[0064] Among them, such as Figures 3 to 6 As shown, the first deformation reinforcement 33 includes a first groove 331. The first groove 331 on the first flexible cover 31 is disposed on the side of the first flexible cover 31 close to the housing 10 along the circumference of the housing 10. The first groove 331 on the first flexible cover 31 extends along the height direction of the housing 10 and passes through the first flexible cover 31. The first groove 331 on the second flexible cover 32 is disposed on the side of the second flexible cover 32 close to the housing 10 along the circumference of the housing 10. The first groove 331 on the second flexible cover 32 extends along the height direction of the housing 10 and passes through the second flexible cover 32. The opening of the first groove 331 faces the outside of the housing 10. When the cleaning assembly 20 moves from the retracted position to the outward expansion position, at least one of the first flexible cover 31 and the second flexible cover 32 needs to be flipped open to the outside of the housing 10 to open the opening 11. At this time, the area where the first groove 331 is located has a significantly reduced local stiffness due to the thinning of the material thickness and the reduction of the cross-sectional area, becoming the area where the first flexible cover 31 and the second flexible cover 32 preferentially undergo bending deformation. The cleaning component 20 requires only a small pushing force to quickly open the first flexible cover 31 and the second flexible cover 32 along the groove towards the outside of the housing 10, reducing the movement resistance of the cleaning component 20. In addition, the first deformation reinforcement 33 can also be configured as a through hole, a blind hole, etc.

[0065] In one embodiment, a plurality of first grooves 331 are provided on the first flexible cover 31, and the plurality of first grooves 331 of the first flexible cover 31 are evenly distributed at intervals along the length direction of the first flexible cover 31. In another embodiment, a plurality of first grooves 331 are provided on the second flexible cover 32, and the plurality of first grooves 331 of the second flexible cover 32 are evenly distributed at intervals along the length direction of the second flexible cover 32. It can be understood that the above embodiments can be implemented individually or simultaneously, and both the first flexible cover 31 and the second flexible cover 32 are provided with a plurality of evenly spaced first grooves 331.

[0066] In one embodiment, the first flexible cover 31 comprises at least one of thermoplastic polyurethane elastomer and thermoplastic elastomer. The second flexible cover 32 comprises at least one of thermoplastic polyurethane elastomer and thermoplastic elastomer. The thermoplastic polyurethane elastomer and thermoplastic elastomer have an elastic deformation range of 300%-800%, which can withstand the forces frequently applied by the cleaning component 20 or obstacles, and can prevent problems such as sealing failure of the opening 11 due to material hardening or fracture. After the cleaning component 20 retracts, the thermoplastic polyurethane elastomer and thermoplastic elastomer quickly reset due to the reversible deformation ability of the molecular chains, ensuring a tight seal of the opening 11. Compared with materials such as silicone, the rebound speed of thermoplastic polyurethane elastomer and thermoplastic elastomer is 30%-50% faster, which can reduce the intrusion of debris into the interior of the shell 10 during the reset delay time. Furthermore, thermoplastic polyurethane elastomers and thermoplastic elastomers also possess excellent wear resistance and tear resistance. In scenarios where the cleaning component 20 repeatedly rubs against the first flexible cover 31 and the second flexible cover 32, the surfaces of the first flexible cover 31 and the second flexible cover 32 are not prone to fraying or damage, thus extending their service life. Even if the first flexible cover 31 and the second flexible cover 32 are scratched by sharp foreign objects, they are not prone to cracking, which can prevent the opening 11 from failing and further extend the service life of the first flexible cover 31 and the second flexible cover 32.

[0067] In one embodiment, along the circumference of the housing 10, the first flexible cover 31 and the second flexible cover 32 are respectively provided with a first snap-fit ​​portion 34 on the side near the housing 10, and the housing 10 is provided with a second snap-fit ​​portion 12 that cooperates with the first snap-fit ​​portion 34. The cooperation between the first snap-fit ​​portion 34 and the second snap-fit ​​portion 12 allows the first flexible cover 31 and the second flexible cover 32 to be installed on the housing 10, thereby improving the efficiency of assembling and disassembling the first flexible cover 31 and the second flexible cover 32.

[0068] The first engaging portion 34 is disposed on the side of the first flexible cover 31 and the second flexible cover 32 near the cleaning component 20, and the second engaging portion 12 is disposed on the inner wall surface of the housing 10. The first engaging portion 34 includes a protrusion 121, and the second engaging portion 12 includes a groove 341 adapted to the protrusion 121. Alternatively, the first engaging portion 34 includes a groove 341, and the second engaging portion 12 includes a protrusion 121 adapted to the groove 341. The protrusion 121 and the groove 341 cooperate to stably fix the first flexible cover 31 and the second flexible cover 32 to the housing 10. Furthermore, the protrusion 121 and the groove 341 are located on the inner side of the housing 10, ensuring that the outer periphery of the housing 10 is relatively flat, thus improving the aesthetics of the cleaning equipment. When assembling or disassembling the first flexible cover 31 and the second flexible cover 32, the first engaging portion 34 is pushed or pulled along the extending direction of the second engaging portion 12 to engage or disengage the first engaging portion 34 from the second engaging portion 12. The mating surfaces of the protrusion 121 and the slot 341 can be designed as a labyrinth structure, for example, the protrusion 121 can be set with multiple steps to enhance stability. In addition, the inner wall surfaces of the protrusion 121 and the slot 341 are tightly fitted to prevent dirt from entering between the protrusion 121 and the slot 341 or into the interior of the housing 10.

[0069] The locking protrusion 121 is disposed on the inner wall surface of the housing 10, and the locking groove 341 extends along the height direction of the housing 10 to the bottom end of the housing 10. A stop protrusion 13 is also provided on the inner wall surface of the housing 10, located on the outer side of the locking protrusion 121 to at least limit the position of the first locking portion 34 on the locking protrusion 121. When assembling or disassembling the first locking portion 34, the first locking portion 34 is pushed or pulled along the extension direction of the locking groove 341 to engage or disengage the locking protrusion 121 from the locking groove 341. When the locking groove 341 is installed in place, the stop protrusion abuts against the first locking portion 34, limiting the first locking portion 34 and preventing the first locking portion 34 from detaching from the housing 10 under external force.

[0070] In addition, a mounting member 14 can be provided on the housing 10. The mounting member 14 has a mounting groove 141. The aforementioned snap protrusion 121 is provided at the inner edge of the mounting groove 141. The aforementioned stop protrusion 13 is provided on the inner wall surface of the mounting groove 141, and the first snap-fit ​​portion 34 is at least partially located in the mounting groove 141.

[0071] The cleaning assembly 20 includes a drive mechanism 21 and a cleaning component 22 connected to the drive mechanism 21. The drive mechanism 21 is installed inside the housing 10 and can rotate relative to the housing 10 to switch the cleaning assembly 20 between an inward position and an outward position. The cleaning assembly 20 switches between the inward and outward positions about a swing center 23. A second cover plate component is disposed near the swing center 23. Along the circumference of the housing 10, the length of the first cover plate component is greater than the length of the second cover plate component. Figure 15As shown, the drive mechanism 21 can drive the cleaning component 22 to rotate relative to the ground to clean the ground. The drive mechanism 21 can also drive the cleaning component 22 to swing relative to the housing 10 about the swing center 23 to switch between an inward position and an outward position, so that the cleaning component 22 can swing to the outward position to clean corner blind areas.

[0072] During the swinging process of the cleaning component 20 from the retracted position to the outward expansion position, the cleaning component 22 swings relative to the housing 10 along a first direction (as indicated by arrow A in the figure). The end of the drive mechanism 21 away from the swing center 23 moves from inside the housing 10 to pass through the opening 11 and then swings to the outside of the housing 10. In this process, the end of the drive mechanism 21 away from the swing center 23 first contacts the first cover plate component and applies a pushing force to the first cover plate component to push the first cover plate component to open at least part of the opening 11. The end of the drive mechanism 21 away from the swing center 23 moves from inside the housing 10 to the opened portion of the opening 11 and continues to swing along the first direction. The end of the drive mechanism 21 away from the swing center 23 continues to move to contact the second cover plate component and applies a pushing force to the second cover plate component to push the second cover plate component to open at least part of the opening 11, until the drive mechanism 21 swings to its final position. When the cleaning component 20 swings from the retracted position to the outward expansion position, the second cover plate component is positioned close to the swing center 23, meaning the second flexible cover 32 is positioned close to the swing center 23. This causes the second flexible cover 32 to move closer to the drive mechanism 21, thereby increasing the space K (e.g., the space formed by the surface of the second flexible cover 32 and the outer surface of the drive mechanism 21) between them. Figure 15 The smaller size of the shaded area (in the diagram) reduces the gap between the second flexible cover 32 and the drive mechanism 21, thus reducing the risk of debris and other obstacles entering the housing 10 through the space K. This effectively prevents damage to the internal components of the housing 10 from debris and other obstacles. In addition, a smaller space K also improves the aesthetics of the cleaning equipment.

[0073] The opening 11 has a first side 111 and a second side 112 arranged opposite to each other along the circumference of the housing 10. The first cover plate component is arranged close to the first side 111, and the second cover plate component is arranged close to the second side 112. When the cleaning assembly 20 moves between the retracted position and the outward expansion position, the minimum distance between the first side 111 and the outer wall of the drive mechanism 21 is S1. The outer wall of the drive mechanism 21 is tangent to the first cover plate component and forms a first tangent position. The distance between the first side 111 and the first tangent position is S2. The outer wall of the drive mechanism 21 is tangent to the second cover plate component and forms a second tangent position. The distance between the second side 112 and the second tangent position is S3. The length of the first cover plate component is X1, the length of the second cover plate component is X2, and the arc length between the opposite sides of the opening 11 along the circumference of the housing 10 is L. X1, X2, L, S1, S2, and S3 satisfy the following relationship: S1 < X1 ≤ S2, X2 ≥ L - X1, and X2 ≤ S3.

[0074] Where S1 < X1 ≤ S2, meaning the length of the first cover plate component is greater than the minimum distance between the first side 111 and the outer wall of the drive mechanism. During the movement of the drive mechanism 21 from the retracted position to the expanded position, the end of the first cover plate component away from the housing 10 is prevented from separating from the drive mechanism 21. When the cleaning assembly 20 moves from the expanded position to the retracted position, the first cover plate component effectively prevents it from obstructing the movement of the drive mechanism 21. If X1 = S1, during the movement of the drive mechanism 21, the first cover plate component may press against the drive mechanism 21, preventing the drive mechanism 21 from retracting smoothly. In this embodiment, the length of the first cover plate component is relatively long, ensuring that the first cover plate component is always connected to the drive mechanism 21 in the second state, ensuring that the drive mechanism 21 can move smoothly.

[0075] In order to ensure that the first cover plate component and the second cover plate component can cover the opening 11 when the shielding component 30 is in the first state, and the second cover plate component overlaps with the first cover plate component at least partially, X2≥L-X1 is set in this embodiment to effectively prevent garbage from entering the interior of the housing 10 through the opening 11.

[0076] When the cleaning component 20 moves from the inward position to the outward position, the end of the second cover plate component away from the housing can abut and be tangent to the end of the drive mechanism 21 away from the swing center 23 to form a second tangent position. In this embodiment, X2≤S3 is set to ensure that the end of the second cover plate component away from the housing 10 does not exceed the end of the drive mechanism 21. The second cover plate component can also provide a certain support to the drive mechanism 21 to improve the stability of the drive mechanism 21.

[0077] The length of the first cover component is greater than the length of the second cover component. In this embodiment, this can also be expressed as the length L1 of the first flexible cover 31 being greater than the length L2 of the second flexible cover 32. Because the second flexible cover 32 is shorter, when the cleaning component 20 moves from the retracted position to the outward expansion position, the end of the second flexible cover 32 away from the housing can abut against the end of the drive mechanism 21 away from the swing center 23, ensuring that the end of the second flexible cover 32 away from the housing 10 does not exceed the length of the end of the drive mechanism 21 by too much. Simultaneously, to ensure that the opening 11 is covered when the shielding component is in the first state, the first flexible cover 31 needs to extend a certain length and cover the opening together with the second flexible cover 32. During the movement of the drive mechanism 21 from the outward expansion position to the retracted position, to prevent the first flexible cover 31 from detaching from the drive mechanism 21 and hindering its movement, in this embodiment, the first flexible cover 31 is longer, ensuring that the first flexible cover 31 is always connected to the drive mechanism 21 when the shielding component is in the second state, ensuring that the drive mechanism 21 can move smoothly.

[0078] If the length of the first flexible cover 31 is small, when the drive mechanism 21 moves to the outward expansion position, the end of the first flexible cover 31 away from the housing 10 will separate from the drive mechanism 21, and the first flexible cover 31 may also cover at least part of the opening 11. When the cleaning component 20 moves from the outward expansion position to the inward retraction position, the first flexible cover 31 will hinder the movement of the drive mechanism 21.

[0079] Example 2:

[0080] like Figures 7 to 14 As shown, the first cover component includes a first hard cover 301. The second cover component includes a second hard cover 302. The first hard cover 301 and the second hard cover 302 are rotatably connected to the housing 10. An elastic member 303 is provided on the outer edge of at least one of the first hard cover 301 and the second hard cover 302. The elastic member 303 deforms under the action of an external force and recovers its deformation after the external force is removed. When the shielding assembly 30 is in the first state, the elastic member 303, the first hard cover 301 and the second hard cover 302 together cover the opening 11. During the movement of the cleaning assembly 20 from the retracted position to the outward expansion position, the cleaning assembly 20 applies a force to at least one of the first hard cover 301, the second hard cover 302 and the elastic member 303 to change the shielding assembly 30 from the first state to the second state. The elastic component 303 is disposed on the outer edge of at least one of the first hard cover 301 and the second hard cover 302. When the cleaning component 20 is cleaning in the outward position, the elastic component 303 comes into contact with a low, suspended obstacle. The elastic component 303 can deform to avoid the obstacle, effectively preventing the first cover component from being jammed or damaged by the obstacle, and extending the service life of the shielding component 30.

[0081] Specifically, the elastic component 303 can be independently connected to the outer edge of the contour of the first hard cover 301 and protrude beyond the contour of the first hard cover 301. During the movement of the cleaning component 20 from the retracted position to the outward expansion position, the cleaning component 20 drives the first hard cover 301 and the elastic component 303 to rotate relative to the housing 10 to open at least part of the opening 11, ensuring that the cleaning component 20 can move smoothly between the outward expansion position and the retracted position. When the cleaning component 20 is in the outward expansion position performing cleaning work and moving along the edge, low, suspended obstacles may obstruct the movement of the cleaning component 20. At this time, the elastic component 303 deforms upon contact with the obstacle to avoid it. The elastic component 303 effectively prevents the first hard cover 301 from being jammed and damaged by the obstacle, effectively preventing the movement of the cleaning component 20 from being obstructed and other components inside the cleaning equipment from being jammed and damaged, thus helping to extend the service life of the cleaning equipment. When the cleaning component 20 moves from the outward position to the inward position, the force applied by the cleaning component 20 to the shielding component 30 is removed, and the first hard cover 301 and the second hard cover 302 can return to the first state to cover the opening 11, effectively preventing garbage from entering the interior of the housing 10.

[0082] Alternatively, the elastic member 303 may be individually connected to the outer edge of the contour of the second hard cover 302 and protrude beyond the contour of the first hard cover 301. Alternatively, the elastic member 303 may be connected to the outer edges of both the contour of the first hard cover 301 and the contour of the second hard cover 302. Alternatively, the elastic member 303 may also be disposed on the side of the first hard cover 301 or the second hard cover 302 opposite to the cleaning assembly 20, and the edge of the elastic member 303 at least partially extends beyond the contour of the corresponding first hard cover 301 and the second hard cover 302. Alternatively, the elastic member 303 may be disposed on the side of both the first hard cover 301 and the second hard cover 302 opposite to the cleaning assembly 20, and the edge of the elastic member 303 at least partially extends beyond the contour of the first hard cover 301 and the second hard cover 302.

[0083] in, Figures 9 to 11 This is a schematic diagram showing the connection between the first hard cover 301 and the elastic member 303. The connection between the second hard cover 302 and the elastic member 303 can be referenced to the first hard cover 301 (the shaded area in the diagram represents the elastic member 303). The elastic member 303 can be at least partially connected to the outer contour edge of the first hard cover 301 and / or the outer contour edge of the second hard cover 302 by nesting, embedding, or wrapping (e.g., ...). Figure 9 (As shown). Alternatively, the elastic member 303 may at least partially be spliced ​​to the outer contour edge of the first hard cover 301 and / or the outer contour edge of the second hard cover 302 (as shown). Figure 10 (As shown). Alternatively, the elastic member 303 may at least partially overlap the outer contour edge of the first hard cover 301 and / or the outer contour edge of the second hard cover 302 (as shown). Figure 11(As shown). It is understood that the connection between the elastic member 303 and the first hard cover 301 and / or the second hard cover 302 can also be configured in other forms. This embodiment does not impose a unique limitation on the connection method between the elastic member 303 and the first hard cover 301 and / or the second hard cover 302. The elastic member 303 and the first hard cover 301 and / or the second hard cover 302 can be configured as an integrally formed structure or as a detachable structure.

[0084] Among them, such as Figures 12 to 14 As shown, a first hard cover 301 and a second hard cover 302 are arranged at intervals along the circumference of the housing 10. The sides of the first hard cover 301 and the second hard cover 302 away from each other are rotatably connected to the housing 10. The elastic member 303 includes an elastic cover 3031. The elastic cover 3031 is disposed on the side of at least one of the first hard cover 301 and the second hard cover 302 opposite to the cleaning assembly 20. The elastic cover 3031 on the first hard cover 301 extends to the outer edge of the first hard cover 301. The elastic cover 3031 on the second hard cover 302 extends to the outer edge of the second hard cover 302. The elastic cover 3031 extending to the outer edge of the first hard cover 301 and the second hard cover 302 forms a "soft buffer boundary". When the cleaning assembly 20 is cleaning in the outward position, the elastic cover 3031 absorbs the impact force through elastic deformation after contacting an obstacle, and can avoid the obstacle, effectively reducing the risk of damage to the shielding assembly 30. Furthermore, the resilient cover 3031 is located on the outer surface of the housing 10 and is positioned away from the cleaning assembly 20. This prevents the resilient cover 3031 from interfering with the cleaning assembly 20 inside the housing 10, and also protects the first hard cover 301 and the second hard cover 302 from direct contact with obstacles. The resilient cover 3031's location on the outer surface of the housing 10 also enhances the aesthetics of the cleaning equipment.

[0085] In one embodiment, the resilient cover 3031 is provided with a snap-fit ​​groove 3032. A first hard cover 301 is at least partially embedded in the snap-fit ​​groove 3032 and is press-fitted against the inner wall of the snap-fit ​​groove 3032. A second hard cover 302 is at least partially embedded in the snap-fit ​​groove 3032 and is press-fitted against the inner wall of the snap-fit ​​groove 3032. The first hard cover 301 and the second hard cover 302 can be embedded in the snap-fit ​​groove 3032 and press-fitted against the inner wall of the groove, forming a tight connection with the resilient cover 3031 through mechanical compression. This eliminates the need for additional screws, glue, or other fasteners, simplifying the assembly process while ensuring that the resilient cover 3031 and the hard cover are not easily separated. Even if the cleaning equipment is bumped during movement or the cleaning component 20 swings at high frequency, the resilient cover 3031 is not easily detached, improving the structural reliability of the cleaning equipment. The shape of the snap-fit ​​groove 3032 can be customized according to the edge contours of the first hard cover 301 and the second hard cover 302. During installation, the guide design allows for quick alignment, ensuring the relative position of the elastic cover 3031 with the first hard cover 301 and the second hard cover 302 is fixed. This avoids incomplete coverage of the opening 11 or movement interference caused by misalignment, reducing assembly errors. Simultaneously, the modularly configured first hard cover 301, second hard cover 302, and elastic cover 3031 are physically connected to achieve detachability. When the elastic cover 3031 ages or breaks due to long-term use, it is not necessary to disassemble the entire shielding assembly 30 or the housing 10; only the elastic cover 3031 needs to be replaced, reducing maintenance costs and user operation difficulty. The elastic cover 3031 includes at least one of thermoplastic polyurethane elastomer and thermoplastic elastomer.

[0086] Alternatively, the first hard cover 301 and the second hard cover 302 can be fixed to the elastic cover 3031 by other connection methods. For example, the elastic cover 3031 can be glued to the first hard cover 301 and the second hard cover 302. This embodiment is not the only one.

[0087] Furthermore, the elastic cover 3031 is connected to the first hard cover 301. When the blocking assembly 30 is in the first state, the elastic cover 3031 covers one side of the opening 11, and the second hard cover 302 covers the other side of the opening 11 and abuts against the elastic cover 3031. Along the circumference of the housing 10, the length of the elastic cover 3031 is greater than the length of the second hard cover 302. Referring to the above embodiment 1, when the cleaning assembly 20 swings from the retracted position to the outward expansion position, the cleaning component 22 swings relative to the housing 10 along the first direction (as indicated by arrow A in the figure). The end of the drive mechanism 21 away from the swing center 23 first contacts the first hard cover 301 or the elastic cover 3031 and applies a pushing force to push the elastic cover 3031 to open at least part of the opening 11. The end of the drive mechanism 21 away from the swing center 23 moves from inside the housing 10 to the part of the opening 11 that is open and continues to swing along the first direction. The end of the drive mechanism 21 away from the swing center 23 continues to move until it contacts the second hard cover 302 and applies a pushing force to the second hard cover 302 to rotate and open at least part of the opening 11, until the drive mechanism 21 swings into place. When the cleaning assembly 20 swings into place from the retracted position to the outward expansion position, because the second hard cover 302 is positioned close to the swing center 23, the second hard cover 302 is brought closer to the drive mechanism 21, thereby increasing the space K (e.g., the space formed by the surface of the second hard cover 302 near the cleaning assembly 20 and the outer surface of the drive mechanism 21) is closer to the drive mechanism 21. Figure 15 The smaller size of the shaded area (in the diagram) reduces the gap between the second hard cover 302 and the drive mechanism 21, thus reducing the risk of debris and other obstacles entering the housing 10 through the space K. This effectively prevents damage to the internal components of the housing 10 from debris and other obstacles. In addition, the smaller space K also improves the aesthetics of the cleaning equipment.

[0088] like Figures 13 to 15 As shown, the first cover component includes an elastic cover 3031 and a first hard cover 301. The first hard cover 301 is disposed on the side of the elastic cover 3031 near the swing center 23, and the outer edge of the elastic cover 3031 extends to the outer edge of the first hard cover 301. The second cover component includes a second hard cover 302. Along the circumference of the housing 10, the first hard cover 301 and the second hard cover 302 are arranged at intervals. The sides of the first hard cover 301 and the second hard cover 302 away from each other are rotatably connected to the housing 10. The opening 11 has a first side 111 and a second side 112 arranged opposite to each other along the circumference of the housing 10. The first hard cover 301 is arranged near the first side 111, and the second hard cover 302 is arranged near the second side 112.

[0089] Referring to the above embodiment, as the cleaning component 20 swings from the retracted position to the outward expansion position, the cleaning component 22 swings relative to the housing 10 along a first direction (as indicated by arrow A in the figure). The end of the drive mechanism 21 away from the swing center 23 first contacts the first hard cover 301 or the elastic cover 3031 and applies a pushing force to push the elastic cover 3031 to open at least part of the opening 11. The end of the drive mechanism 21 away from the swing center 23 moves from inside the housing 10 to the part where the opening 11 is open and continues to swing along the first direction. The end of the drive mechanism 21 away from the swing center 23 continues to move until it contacts the second hard cover 302 and applies a pushing force to the second hard cover 302 to rotate and open at least part of the opening 11, until the drive mechanism 21 swings to its final position. When the cleaning component 20 swings from the inward position to the outward position, the second hard cover 302 is positioned close to the swing center 23, causing the second hard cover 302 to move closer to the drive mechanism 21. This results in the second hard cover 302 approaching the space K (e.g., the space formed by the surface of the cleaning component 20 and the outer surface of the drive mechanism 21) formed by the surface of the second hard cover 302 and the outer surface of the drive mechanism 21. Figure 15 The smaller size of the shaded area (in the diagram) reduces the gap between the second hard cover 302 and the drive mechanism 21, thus reducing the risk of debris and other obstacles entering the housing 10 through the space K. This effectively prevents damage to the internal components of the housing 10 from debris and other obstacles. In addition, the smaller space K also improves the aesthetics of the cleaning equipment.

[0090] Where S1 < X1 ≤ S2, that is, the length X1 of the elastic cover 3031 and the length of the first hard cover 301 are greater than the minimum distance between the first side 111 and the outer wall of the drive mechanism. When the drive mechanism 21 moves from the retracted position to the expanded position, it ensures that the end of the elastic cover 3031 away from the housing 10 does not separate from the drive mechanism 21. When the cleaning component 20 moves from the expanded position to the retracted position, it effectively prevents the elastic cover 3031 from obstructing the movement of the drive mechanism 21. If X1 = S1, during the movement of the drive mechanism 21, the first hard cover 301 may press against the drive mechanism 21, causing the drive mechanism 21 to be unable to retract smoothly. In this embodiment, the elastic cover 3031 is relatively long, ensuring that the elastic cover 3031 is always connected to the drive mechanism 21 in the second state, ensuring that the drive mechanism 21 can move smoothly. In addition, the elastic cover 3031 and the end of the drive mechanism 21 away from the swing center 23 are flexibly connected. At least part of the elastic cover 3031 near the drive mechanism 21 can abut against the drive mechanism 21, ensuring that when the cleaning component 20 is in the second position, the elastic cover 3031 and the drive mechanism 21 can also effectively block garbage from entering the housing 10.

[0091] When the cleaning component 20 moves from the inward position to the outward position, the end of the second hard cover 302 away from the housing can abut and be tangent to the end of the drive mechanism 21 away from the swing center 23 to form a second tangent position. In this embodiment, X2≤S3 is set to ensure that the end of the second hard cover 302 away from the housing 10 does not exceed the end of the drive mechanism 21. The second hard cover 302 can also provide a certain support to the drive mechanism 21 to improve the stability of the drive mechanism 21.

[0092] In this embodiment, along the circumference of the housing 10, the length of the first hard cover 301 is X3, and the length of the elastic cover 3031 is X1. X3 and X1 satisfy the following relationship: 0 < X3 / X1 ≤ 75%. For example, the value of X3 / X1 can be set to one of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 75%, etc. When the cleaning component 20 is in the outward expansion position, this embodiment can ensure that the end of the elastic cover 3031 can fit against the drive mechanism 21 and that the end of the elastic cover 3031 does not bend inward and hinder the movement of the cleaning component 20. Furthermore, the elastic cover 3031 has a certain degree of rigidity, further ensuring that the elastic cover 3031 can stably fit against the drive mechanism 21 when the cleaning component 20 is in the outward expansion position. In addition, the length of the first hard cover 301 is less than the minimum distance between the first side 111 and the outer side wall of the drive mechanism 21. Even when the cleaning component 20 is in the outward-expanding position and the drive mechanism 21 is located outside the housing 10, the first hard cover 301 will not be jammed by the drive mechanism 21 when it is passively retracted. If X3 / X1 = 0, it can be considered that the first hard cover 301 is not provided, and the first cover component is an elastic cover 3031. If X3 / X1 > 75%, the length of the first hard cover 301 is too large and the length of the elastic cover 3031 is too small. When blocked by a suspended obstacle, the deformation range of the elastic cover 3031 is too small to avoid the obstacle, and the first cover component and the second cover component are easily damaged by the obstacle.

[0093] Understandably, the specific value of the ratio of X3 to X1 can be adjusted according to the actual situation. The ratio of X3 to X1 can be adaptively adjusted according to the size of the housing 10, the swing amplitude of the cleaning component 20, the size of the drive mechanism 21, etc.

[0094] In one embodiment, the elastic member 303 is at least partially disposed at the top of the first hard cover 301 and protrudes beyond the edge of the first hard cover 301. In another embodiment, the elastic member 303 is at least partially disposed at the top of the second hard cover 302 and protrudes beyond the edge of the second hard cover 302. In another embodiment, the elastic member 303 is at least partially disposed at the end of the first hard cover 301 away from the housing 10 in the longitudinal direction and protrudes beyond the edge of the first hard cover 301. In another embodiment, the elastic member 303 is at least partially disposed at the end of the second hard cover 302 away from the housing 10 in the longitudinal direction and protrudes beyond the edge of the second hard cover 302. It is understood that the above embodiments can be implemented individually or simultaneously. When the elastic member 303 is located at the top of the first hard cover 301 or the second hard cover 302, the elastic member 303 can directly fill the gap between the first hard cover 301 or the second hard cover 302 and the edge of the opening 11 of the housing 10. When the shielding assembly 30 is in the first state, the elastic member 303 can seal the gap, improve the sealing performance of the shielding assembly 30, and reduce the entry of garbage, dust, etc. into the housing 10. Low-hanging obstacles are more likely to come into contact with the top of the first hard cover 301 or the second hard cover 302, or the side of the first hard cover 301 or the second hard cover 302 that is close to each other. Setting the elastic member 303 at these positions can more effectively avoid obstacles and reduce the risk of damage to the shielding assembly 30.

[0095] In one embodiment, the elastic member 303 is provided with a second deformation reinforcement 3033, which is offset from the first hard cover 301 and the second hard cover 302. The second deformation reinforcement 3033 can guide the elastic member 303 to deform in a specific direction when subjected to force. For example, when the elastic member 303 is subjected to a lateral force from an obstacle outside the housing 10, the second deformation reinforcement 3033 preferentially bends and deforms, dispersing the lateral force to multiple directions and deforming to avoid the obstacle, reducing the risk of the shielding assembly 30 being damaged by the obstacle. The second deformation reinforcement 3033 enables the elastic member 303 to withstand a greater deformation, which is more conducive to the elastic member 303 avoiding obstacles. In addition, by removing material from non-critical stress areas of the elastic member 303, the second deformation reinforcement 3033 can directly reduce the weight of the elastic member 303 and reduce production costs.

[0096] Furthermore, the second deformation reinforcement 3033 includes at least one of a strip groove 30331, a blind hole, and a through hole. The strip groove 30331 can guide the elastic member 303 to bend in a specific direction. Both the blind hole and the through hole can reduce the thickness of the area on the elastic member 303. When the elastic member 303 is subjected to an external force, the elastic member 303 preferentially deforms from the thinner part to avoid the obstacle.

[0097] Furthermore, a strip-shaped groove 30331 is disposed on the side of the elastic member 303 near the cleaning assembly 20, and the length of the strip-shaped groove 30331 extends along the height direction of the housing 10 and passes through the elastic member 303. When the cleaning assembly 20 is in the outward-expanding position and is blocked by a low, suspended obstacle while moving forward or backward, the strip-shaped groove 30331 of the elastic member 303 first deforms, causing the portion of the elastic member 303 away from the housing 10 to bend and deform towards the cleaning assembly 20, thereby avoiding the obstacle and effectively reducing the possibility of the obstructing assembly 30 being jammed and damaged by a low, suspended obstacle. The strip-shaped groove 30331 can improve the deformation capability of the elastic member 303, which is beneficial to improving the elastic member 303's ability to avoid obstacles.

[0098] The cleaning equipment also includes a position adjustment component 40. The position adjustment component 40 is connected to the shielding component 30 to allow the shielding component 30 to return from a second state to a first state. The position adjustment component 40 can be installed in the housing 10, specifically inside or outside the housing 10, or at least partially inside or partially outside, depending on the structure of the position adjustment component 40; this embodiment does not impose a unique limitation. In some embodiments, the position adjustment component 40 can be configured as a drive motor, a take-up roller, and a pull rope. One end of the pull rope is connected to and wound around the take-up roller, and the other end of the pull rope is connected to the shielding component 30. The output shaft of the drive motor is connected to the take-up roller, thereby allowing the controller within the cleaning equipment to control the drive motor to rotate forward and backward to perform take-up or unwinding operations on the pull rope. When the shielding component 30 needs to rotate from the first state to the second state, the output shaft of the drive motor can be controlled to rotate forward to unwind the pull rope so that the shielding component 30 can rotate in a direction away from the housing 10 to the second state. When the external force on the shielding component 30 is removed and it needs to return to the first state, the output shaft of the drive motor can be controlled to rotate backward to wind the pull rope and pull the shielding component 30 back to the first position. However, the position adjustment component 40 of this structure will consume more energy due to the presence of the drive motor, which will increase the production cost and operating cost of the cleaning equipment.

[0099] In view of the above problems, the position adjustment assembly 40 in this embodiment includes a rotational connecting component 41 and a reset component 42. For example... Figures 12 to 14As shown, a rotating connecting member 41 is disposed on the housing 10, and the first hard cover 301 and the second hard cover 302 are respectively rotatably connected to the housing 10 via the rotating connecting member 41. A reset member 42 is installed between the housing 10 and the first hard cover 301 and / or between the housing 10 and the second hard cover 302. The reset member 42 can reciprocate between a first form and a second form. During the transition of the blocking assembly 30 from the first state to the second state, it causes the reset member 42 to deform from the first form to the second form. During the transition of the blocking assembly 30 to the first state, the reset member 42 has a tendency to deform from the second form to the first form, thereby causing the first hard cover 301 and the second hard cover 302 to return to the first form.

[0100] As can be seen, in this embodiment, the shielding component 30 can be rotatably connected to the housing 10 by the provided rotating connecting component 41, so that the shielding component 30 can reciprocate between the first state and the second state. At the same time, by the reset component 42 installed on the housing 10 and the shielding component 30, the shielding component 30 can be driven back to the first state by the elastic deformation tendency of the reset component 42 when the external force is removed. The reset operation of the shielding component 30 can be realized without the need to set up additional driving components, which can reduce the energy consumption of the cleaning equipment and the production and use costs.

[0101] The rotating connection component 41 includes a fixed base 411 and a rotating shaft 412. Along the circumference of the housing 10, the fixed base 411 is located near the opening 11, specifically at the inner circumferential edge of the opening 11 along the circumference of the housing 10, or at the inner circumferential edge of the housing 10 near the opening 11. The axis of the rotating shaft 412 is parallel to the height direction of the housing 10, meaning the rotating shaft 412 is vertically installed. At least one end of the rotating shaft 412 is fixedly connected to the fixed base 411. The blocking component 30 is connected to the rotating shaft 412 and can rotate around the axis of the rotating shaft 412. In this embodiment, the rotating shaft 412 is mounted on the housing 10 via the fixed base 411, allowing the blocking component 30 to be rotatably connected to the rotating shaft 412. This rotating connection component 41 has a simple structure and is easy to assemble. Specifically, when the shielding assembly 30 includes a first hard cover 301 and a second hard cover 302, the ends of the first hard cover 301 and the second hard cover 302 that are away from each other are rotatably connected to the rotating shaft 412. The fixing seats 411 for fixing the rotating shaft 412 may include at least two, and the at least two fixing seats 411 are spaced apart along the height direction of the housing 10. The opposite ends of the rotating shaft 412 are respectively fixedly connected to at least one fixing seat 411, thereby improving the connection stability and reliability of the rotating shaft 412 on the housing 10. The fixing seats 411 can be connected to the housing 10 by welding, snap-fitting, riveting, screws, bolts, etc. The fixing seats 411 can also be integrally formed with the housing 10. Integral forming not only ensures better connection strength between the fixing seats 411 and the housing 10, but also improves the overall production efficiency of the cleaning equipment.

[0102] The rotating shaft 412 can be welded to the fixed base 411 by welding, or fixed to the fixed base 411 by locking components (such as screws and bolts). However, in order to improve the assembly efficiency and reduce the assembly difficulty between the rotating shaft 412 and the fixed base 411, in this embodiment, a through hole 4111 can be provided in the fixed base 411 along the height direction of the housing 10. The rotating shaft 412 is inserted into the through hole 4111 along the height direction of the housing 10, and the two ends of the rotating shaft 412 are interference-fitted with the corresponding through holes 4111 to achieve the connection between the two.

[0103] When the rotating shaft 412 is mounted on the housing 10 via the fixing seat 411 and located on the side of the opening 11 along the circumference of the housing 10, the rotating shaft 412 and the fixing seat 411 can be located on the inner circumference of the opening 11 or on the outer wall of the housing 10. To make the overall structure of the cleaning equipment neat and aesthetically pleasing, in this embodiment, the rotating shaft 412 is fixed to the inner wall surface of the housing 10 near the cleaning component 20 via the fixing seat 411. The rotating connecting component 41 also includes a connecting arm 413. One end of the connecting arm 413 is connected to the side of the shielding component 30 near the rotating shaft 412, and the other end is rotatably connected to the rotating shaft 412. When the shielding assembly 30 includes a first hard cover 301 and a second hard cover 302, the connecting arm 413 may include at least two. At least one connecting arm 413 is fixedly connected to the side of the first hard cover 301 near the rotating shaft 412 (or may be integrally formed with the first hard cover 301), and the end of the at least one connecting arm 413 connected to the first hard cover 301 away from the first hard cover 301 is rotatably connected to the rotating shaft 412. Similarly, at least another connecting arm 413 is fixedly connected to the side of the second hard cover 302 near the rotating shaft 412 (or may be integrally formed with the second hard cover 302), and the end of the at least one connecting arm 413 connected to the second hard cover 302 away from the second hard cover 302 is rotatably connected to the rotating shaft 412. The connecting arm 413 has a connecting groove 4131 on the side near the inner wall of the cleaning component 20. When the shielding component 30 rotates to the second state, the inner circumference of the opening 11 is located in the connecting groove 4131, so that the opening 11 will not interfere with the rotation of the shielding component 30 during the rotation to the second state, and the overall structure is compact and reliable. For example, when the first hard cover 301 and the second hard cover 302 rotate to the second state, along the circumference of the housing 10, the inner circumference of the opening 11 near the first hard cover 301 is located in the connecting groove 4131 on the connecting arm 413 connected to the first hard cover 301, and the inner circumference of the opening 11 near the second hard cover 302 is located in the connecting groove 4131 on the connecting arm 413 connected to the second hard cover 302, so that when the first hard cover 301 and the second hard cover 302 move to the second state, the inner circumference of the opening 11 will not interfere with the rotation of the first hard cover 301 and the second hard cover 302. When the shielding component 30 is rotated to the first state, the connecting arm 413 is located inside the cleaning component 20, that is, the connecting arm 413 is not exposed outside the housing 10, which improves the aesthetics and neatness of the overall structure of the cleaning equipment.

[0104] like Figure 12As shown, the reset component 42 includes a torsion spring 421, which includes a spring portion 4211 and a first torsion arm 4212. The spring portion 4211 is sleeved on the rotating shaft 412. Along the axial direction of the rotating shaft 412, the spring portion 4211 has a first torsion arm 4212 on each side. One of the first torsion arms 4212 abuts against the housing 10, and the other first torsion arm 4212 is fixedly connected to the side of the blocking assembly 30 near the rotating shaft 412 (specifically, it can be fixedly connected to the connecting arm 413). Thus, when the torsion spring 421 is in the first state, the included angle between the first torsion arms 4212 on each side of the spring portion 4211 is larger, and when the torsion spring 421 is in the second state, the included angle between the first torsion arms 4212 on each side of the spring portion 4211 is smaller. During the process of the blocking assembly 30 rotating from the first state to the second state, the included angle between the spring part 4211 and the first torsion arms 4212 on both sides gradually decreases, so that the torsion spring 421 deforms from the first form to the second form. When the external force on the blocking assembly 30 is removed, the included angle between the spring part 4211 and the first torsion arms 4212 on both sides tends to increase under the elastic force of the spring part 4211, that is, the torsion spring 421 tends to deform from the second form to the first form, thereby driving the blocking assembly 30 to return from the second state to the first state. Thus, the reset operation of the blocking assembly 30 can be achieved by the elastic force of the torsion spring 421 itself. Moreover, the torsion spring 421 is easy to process and obtain, and the assembly with the rotating shaft 412, the housing 10 and the blocking assembly 30 is also more convenient and easier to operate.

[0105] When the shielding assembly 30 includes a first hard cover 301 and a second hard cover 302, if the first hard cover 301 and the second hard cover 302 are in the first state, the torsion spring 421, under its own elastic force and in conjunction with the stop component, can stably and reliably abut the first hard cover 301 and the second hard cover 302 against the first state. During the process of the first hard cover 301 and the second hard cover 302 rotating to the second state, the first hard cover 301 and the second hard cover 302 respectively pull the first torsion arm 4212 of the torsion spring 421 connected to itself to twist in a direction closer to the inner wall surface of the housing 10, so that the included angle between the first torsion arm 4212 and another first torsion arm 4212 that abuts against the housing 10 (specifically against the inner wall surface of the housing 10) gradually decreases. When the external force on the first hard cover 301 and the second hard cover 302 is removed, the first torsion arm 4212 connected to the first hard cover 301 and the second hard cover 302 rebounds to a position with a larger angle with the other first torsion arm 4212 under the elastic force of the spring part 4211, thereby pulling the first hard cover 301 and the second hard cover 302 to rebound and abut against the first state.

[0106] The torsion spring 421 has at least two spring portions 4211. The first torsion arms 4212 of two adjacent spring portions 4211 are connected to each other and abut against the housing 10. Along the axial direction of the shaft 412, the outermost first torsion arm 4212 of the torsion spring 421 is fixedly connected to the shielding assembly 30. Thus, in this embodiment, the shielding assembly 30 and the housing 10 are elastically connected together by the torsion spring 421 with at least two spring portions 4211. This can better balance the weight of the shielding assembly 30 (first hard cover 301 and second hard cover 302), ensuring that the shielding assembly 30 is more stable when opening and closing the opening 11. This helps to reduce the swaying or tilting of the shielding assembly 30 during rotation and ensures a uniform load distribution. Secondly, the torsion spring 421, which includes at least two spring parts 4211, can distribute the weight of the shielding assembly 30 more evenly on each spring part 4211, preventing individual spring parts 4211 from fatigued or damaged prematurely due to excessive force, extending the service life of the torsion spring 421, and reducing the maintenance frequency. In addition, if one spring part 4211 fails or breaks, the other spring parts 4211 and the corresponding torsion arm can still maintain the function of opening and closing the opening 11 of the shielding assembly 30, reducing the situation where the shielding assembly 30 cannot be used due to a single point of failure, and has a high fault tolerance rate.

[0107] The spring portion 4211 of the torsion spring 421 may specifically include two, three, four, or other quantities not less than two. In this case, if the torsion spring 421 includes two spring portions 4211, the torsion spring 421 is a double torsion spring 421 structure, or it may be composed of two single torsion springs 421 each having one spring portion 4211. This embodiment does not limit this to a single configuration. In this embodiment, a tension spring or a compression spring may also be used to replace the torsion spring 421, as long as it ensures that the blocking assembly 30 can return to the second state without interfering with the rotation of the blocking assembly 30 from the first state to the second state.

[0109] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.
