Description

Technical Field

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

[0002] Robotic vacuum cleaners, mops, and floor scrubbers are types of smart home appliances that use artificial intelligence to automatically clean floors in a room. The mop in these devices can wet-clean the floor and move relative to the main unit to reduce cleaning dead spots and improve cleaning effectiveness.

[0003] In this process, during the wet cleaning of the floor, the cleaning equipment uses a water outlet to soak the mop with liquid from a water tank. However, in existing technology, as the mop moves between its retracted and expanded states, liquid can easily splash outside the mop and onto the floor, affecting the cleaning effect and resulting in a poor user experience. Utility Model Content

[0004] The main objective of this application is to provide a cleaning device to solve the problem mentioned in the background art where liquid splashes outside the mop and flows onto the ground, resulting in poor cleaning performance of the cleaning device.

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

[0006] main body;

[0007] A cleaning component is installed at the bottom of the main body and has an inward-retracted state and an outward-expanded state. When the cleaning component is in the outward-expanded state, the portion outside the edge contour of the main body is larger than the portion outside the edge contour of the main body when the cleaning component is in the inward-retracted state. The cleaning component is provided with a flow guiding structure.

[0008] A liquid replenishment assembly includes a liquid supply component and a liquid outlet component. The liquid supply component is disposed on the main body, and the liquid outlet component is disposed on the main body and opposite to the cleaning component. The liquid outlet component can move relative to the main body as the cleaning component moves. The liquid outlet component is provided with a water outlet, which is connected to the liquid supply component. Along the height direction of the main body, at least a portion of the projected outer contour of the water outlet is located within the projected outer contour of the flow guiding structure.

[0009] Furthermore, during the process of the cleaning component moving from one of the retracted state and the outward expansion state to the other, the cleaning component drives the liquid outlet to move synchronously so that the cleaning component and the liquid outlet are relatively stationary along the height direction of the main body.

[0010] Furthermore, during the process of the cleaning component moving from one of the retracted state and the outward expansion state to the other, the cleaning component can perform a first rotational movement relative to the liquid outlet in a first clockwise direction;

[0011] Along the height direction of the main body, the flow guiding structure has a first projected outer contour on the liquid outlet. During the process of the cleaning component moving from one of the inward state and the outward state to the other, the water outlet is always located within the first projected outer contour.

[0012] Furthermore, along the height direction of the main body, a first clearance hole is provided through the main body. The cleaning component has a first distance to move from one of the retracted state and the outward expansion state to the other. The first clearance hole extends from the retracted state to the outward expansion position, and the length of the first clearance hole is not less than the first distance. The cleaning device further includes:

[0013] A drive assembly includes a drive component and a transmission shaft. Along the height direction of the main body, the drive component is located on the side of the main body away from the cleaning component and can move relative to the main body with the cleaning component. The transmission shaft is connected to the drive component and can rotate in a first clockwise direction under the drive of the drive component. The liquid outlet is located between the cleaning component and the drive component and covers the first clearance hole. The end of the transmission shaft away from the drive component passes through the first clearance hole and the liquid outlet and is connected to the cleaning component.

[0014] The water outlet is located relative to the first clearance hole of the liquid outlet component.

[0015] Furthermore, the flow guiding structure includes at least one first through-hole, and the cleaning component includes:

[0016] A tray, which is connected to the drive shaft, and at least one first through hole is provided on the tray along the height direction of the main body;

[0017] A flexible cleaning component is disposed on the surface of the tray away from the main body;

[0018] When the cleaning component is in the retracted state, the first through hole has a second projected outer contour on the liquid outlet along the height direction of the main body. When the cleaning component is in the expanded state, the first through hole has a third projected outer contour on the liquid outlet along the height direction of the main body. The second projected outer contour and the third projected outer contour have an overlapping area, and the water outlet is located in the overlapping area.

[0019] Furthermore, the flow guiding structure has a length L1 along the first clockwise direction. When the cleaning component moves from the retracted state to the expanded state or from the expanded state to the retracted state, the arc distance by which the flow guiding structure moves along the first clockwise direction with the rotation of the cleaning component is L2, and L1 is greater than L2.

[0020] Furthermore, the liquid outlet includes a sealing plate, on which a second clearance hole is provided. The second clearance hole is disposed opposite to and communicates with the first clearance hole. Along the height direction of the main body, the projected outer contour of the first clearance hole is located within the projected outer contour of the sealing plate. The drive shaft passes through the first clearance hole and the second clearance hole and is connected to the cleaning component. The water outlet is located on one side of the second clearance hole and is spaced apart from the second clearance hole.

[0021] Furthermore, the cleaning component can perform a second rotational movement in a second clockwise direction to move from one of the inward state and the outward state to the other. The driving component and the sealing plate can both perform the second rotational movement around the first axis under the drive of the cleaning component. The first clockwise direction is the same as or opposite to the second clockwise direction. Along the radial direction of the transmission shaft, the second clearance hole is spaced apart from the first axis.

[0022] Furthermore, the cleaning component can perform a second rotational movement along a second clockwise direction to move from one of the inward state and the outward state to the other, wherein the first clockwise direction is the same as or opposite to the second clockwise direction, and the cleaning device further includes:

[0023] A connecting assembly is located radially along the drive shaft, connected to the main body and situated on the side of the drive component away from the drive shaft. The liquid outlet and the drive component are respectively connected to the connecting assembly, and both the liquid outlet and the drive component can perform the second rotational movement relative to the connecting assembly under the drive of the cleaning assembly.

[0024] Furthermore, the connection component includes:

[0025] A connecting base is located on the side of the body away from the cleaning component along the height direction of the main body and is fixedly connected to the main body, and an installation space is formed between the connecting base and the main body;

[0026] A connecting shaft is provided along the height direction of the main body. One end of the connecting shaft is fixedly connected to the connecting seat, and the other end of the connecting shaft extends from the installation space to the side of the main body near the cleaning component. The driving component is connected to the portion of the connecting shaft located in the installation space and can perform a second rotational movement around the axis of the connecting shaft. Along the height direction of the main body, the liquid outlet is located on the side of the main body near the cleaning component, and the liquid outlet is rotatably connected to the side of the connecting shaft near the cleaning component.

[0027] Furthermore, a limiting structure is provided between the driving component and the liquid outlet component. The limiting structure is located on one side of the drive shaft along its own radial direction and is disposed opposite to the first clearance hole. Along the radial direction of the drive shaft, the limiting structure is used to keep the liquid outlet component in a stationary state relative to the drive shaft.

[0028] Furthermore, the limiting structure includes:

[0029] The first limiting post is located on the side of the driving component near the liquid outlet and is opposite to the liquid outlet along the height direction of the main body. A first limiting hole is provided in the first limiting post along the height direction of the main body.

[0030] The second limiting post is located along the height direction of the main body and is disposed on the side of the liquid outlet near the driving component. The second limiting post is adapted to the first limiting hole and is at least partially inserted into the first limiting hole.

[0031] Furthermore, the liquid supply component includes:

[0032] Water tank;

[0033] A flexible water outlet pipe is connected between the water tank and the water outlet.

[0034] In this application, the water outlet is located on the liquid outlet component. Since the liquid outlet component moves with the cleaning component, and during the movement of the cleaning component from one of the retracted state and the outward expansion state to the other, the water outlet is at least partially positioned opposite the water receiving structure. When the cleaning component moves to the transition position between the retracted and outward expansion states, the water outlet and the guide structure move synchronously. Along the height direction of the main body, the water outlet remains stationary relative to the guide structure; that is, the water outlet always corresponds to the guide structure. The liquid flowing from the water outlet can flow directly onto the guide structure and will not be splashed out by the cleaning component due to dripping to other parts of the cleaning component. This effectively prevents liquid from splashing outside the guide structure onto the ground or other cleaning surfaces, or walls or other edge obstacles. Therefore, the liquid supplied to the cleaning component will not fall onto the ground during the movement of the cleaning component, ensuring better cleaning results and improving the user experience.

[0048] The mop in a cleaning device can move between an inward-retracting state and an outward-expanding state to switch positions for edge cleaning or normal cleaning. During this movement, liquid can easily flow onto the mop holder, colliding with it and splashing onto the floor, walls, and furniture (such as the bottom of cabinets and table legs). While water dripping onto the floor can be cleaned with a second cleaning cycle, this increases the cleaning burden on the device and reduces cleaning efficiency. If walls are constantly splashed with water, it not only reduces the aesthetics of the surface but also affects its durability, potentially leading to peeling. Some furniture may also rot after being soaked in water for an extended period, reducing its lifespan and resulting in a poor user experience.

[0049] like Figures 1 to 7 As shown, to address the aforementioned problems, this application provides a cleaning device. The cleaning device includes a main body 10, a cleaning component 20, and a liquid replenishment component 30. The cleaning component 20 is mounted on the bottom of the main body 10 and can have an inward-facing state and an outward-facing state. When the cleaning component 20 is in the outward-facing state, the portion outside the edge contour of the main body 10 is larger than the portion outside the edge contour of the main body 10 when the cleaning component 20 is in the inward-facing state. A flow guiding structure 21 is provided on the cleaning component 20. The liquid replenishment component includes a liquid supply component and a liquid outlet 31. The liquid supply component is located on the main body 10. The liquid outlet 31 is located on the main body 10 and is disposed opposite to the cleaning component 20. The liquid outlet 31 can move relative to the main body 10 as the cleaning component 20 moves. The liquid outlet 31 is provided with an outlet 311, which communicates with the liquid supply component. The liquid supply component is at least used to store liquid, and liquid can flow from the liquid supply component to the liquid outlet 31 and flow out from the outlet 311. Along the height direction of the main body (e.g., along the height direction of the main body...) Figure 2 The direction indicated by the middle arrow X (specifically the height direction of the shell) means that at least part of the projected outer contour of the outlet 311 is located within the projected outer contour of the guide structure 21.

[0050] In this embodiment, since the liquid outlet 31 can move with the cleaning component 20, and during the process of the cleaning component 20 moving from one of the retracted state and the outward expansion state to the other, at least part of the projected outer contour of the outlet 311 is located within the projected outer contour of the guide structure 21. When the cleaning component 20 moves to the transition position between the retracted state and the outward expansion state, the outlet 311 and the guide structure 21 move synchronously. Along the height direction of the main body, the outlet 311 is stationary relative to the guide structure 21, that is, the outlet 311 is always corresponding to the guide structure 21. The liquid flowing out of the outlet 311 can flow directly onto the guide structure 21, and will not be splashed out by the cleaning component 20 due to dripping to other positions of the cleaning component 20. This effectively prevents the liquid from splashing outside the guide structure 21 onto the ground or other cleaning surfaces, or walls or other edge obstacles. Therefore, the liquid supplied to the cleaning component 20 will not fall onto the ground during the movement of the cleaning component 20, ensuring that the cleaning equipment can achieve better cleaning results and improving the user experience.

[0051] When the cleaning component 20 cleans along corner areas such as wall corners, the cleaning component 20 is in an outward expansion state, with at least a portion of the cleaning component 20 extending beyond the edge contour of the main body 10. The cleaning component 20 can perform edge cleaning of corner areas such as wall corners, reducing blind spots and dead corners, improving the cleaning rate, achieving ideal cleaning results, and providing a good user experience.

[0052] When the cleaning component 20 is in the retracted state, the cleaning component 20 may be completely within the edge contour of the main body 10 or may partially extend beyond the edge contour of the main body 10.

[0053] In one embodiment, the cleaning component 20 has a first distance to move from one of the retracted state and the outward expansion state to the other. When the cleaning component 20 moves from one of the retracted state and the outward expansion state to the other, the liquid outlet 31 has a second distance to move with the cleaning component 20, and the second distance is equal to the first distance. When the cleaning component 20 moves from one of the retracted state and the outward expansion state to the other, the cleaning component 20 and the liquid outlet 31 can move synchronously and at equal distances along the height direction of the main body. The flow guide structure 21 and the liquid outlet 31 can remain relatively stationary. The water outlet 311 and the flow guide structure 21 will not be misaligned. The water outlet 311 and the flow guide structure 21 can maintain a precise match in relative position. The liquid flowing out of the water outlet 311 can accurately fall into the flow guide structure 21, effectively preventing liquid from splashing outside the flow guide structure 21 onto the ground or other cleaning surfaces, or walls or other edge obstacles, ensuring that the cleaning equipment can achieve better cleaning results and improving the user experience.

[0054] During the movement of the cleaning component 20 from one of the retracted state and the outward expansion state to the other, the cleaning component 20 can perform a first rotational movement relative to the liquid outlet 31 in a first clockwise direction. When the cleaning equipment cleans the ground, the cleaning component 20 comes into contact with the ground. The cleaning component 20 can perform a first rotational movement in a first clockwise direction, which can effectively clean stains and other dirt on the ground. Along the height direction of the main body 10, the guide structure 21 has a first projected outer contour on the liquid outlet 31. During the movement of the cleaning component 20 from one of the retracted state and the outward expansion state to the other, the water outlet 311 is always located within the first projected outer contour.

[0055] During the movement of the cleaning component 20 from either the retracted or expanded state to the other, the water outlet 311 remains within the outer contour of the first projection. Even while the cleaning component 20 is performing its first rotational movement to clean the ground, the water outlet 311 remains aligned with the flow guide structure 21, ensuring that the liquid flowing from the water outlet 311 always flows into the flow guide structure 21. Regardless of whether the cleaning component 20 is performing its first rotational movement or moving from either the retracted or expanded state to the other, the water outlet 311 remains aligned with the flow guide structure 21, ensuring that the liquid flowing from the water outlet 311 accurately falls into the flow guide structure 21. The liquid does not flow outside the cleaning component 20, effectively preventing liquid from splashing outside the flow guide structure 21 onto the ground or other cleaning surfaces, or walls or other edge obstacles.

[0056] In one embodiment, a first clearance hole 11 is provided through the body 10 along its height direction, and the cleaning component 20 has a first distance to move from one of an inward-facing state to the other of an outward-facing state. The first clearance hole 11 extends from the inward-facing state to the outward-facing position, and the length of the first clearance hole 11 is not less than the first distance. The cleaning device also includes a drive assembly 40. The drive assembly 40 includes a drive component 41 and a drive shaft 43. Along the height direction of the body 10, the drive component 41 is located on the side of the body 10 away from the cleaning component 20 and can move relative to the body 10 with the cleaning component 20. The drive shaft 43 is connected to the drive component 41 and can rotate in a first clockwise direction under the drive of the drive component 41. The end of the drive shaft 43 away from the drive component 41 passes through the first clearance hole 11 and is connected to the cleaning component 20. A liquid outlet 31 is located between the cleaning component 20 and the drive component 41 and covers the first clearance hole 11. The water outlet 311 is located at the position of the liquid outlet 31 relative to the first clearance hole 11. The liquid outlet 31 can be configured to be connected to the drive component 41.

[0057] The drive shaft 43 passes through the first clearance hole 11, and the length of the first clearance hole 11 is not less than the first distance. The first clearance hole 11 provides sufficient space for the movement of the drive shaft 43, so that the drive shaft 43 can smoothly drive the cleaning component 20 to reciprocate between the inward and outward states. The normal movement of the cleaning component 20 will not be affected by the obstruction of the main body 10, ensuring that the cleaning component 20 can flexibly adjust the cleaning range and improve the cleaning efficiency and cleaning effect.

[0058] The liquid outlet 31 can be positioned on the side of the main body 10 closer to the cleaning component 20 in the height direction, or on the side of the main body 10 away from the cleaning component 20 in the height direction. When the liquid outlet 31 is positioned in the space between the main body 10 and the cleaning component 20, the internal structure of the cleaning equipment becomes more compact, improving space utilization and reducing the size of the equipment, making it lighter and easier to operate. The liquid outlet 31 can also effectively seal the gap between the first clearance hole 11 and the drive component 40, preventing liquid from splashing into the drive component 40 inside the main body 10 through these gaps, effectively preventing liquid leakage from damaging the drive component 40, ensuring the cleanliness and dryness of the inside of the cleaning equipment, and extending the service life of the cleaning equipment. The liquid outlet 31 is connected to the drive component 41, allowing the liquid outlet 31 to move with the drive component 41 and the cleaning component 20, ensuring that the outlet 311 can move relative to the guide structure 21 for alignment. During the movement of the cleaning component 20 between the retracted state and the expanded state, the water outlet 311 can always accurately align with the guide structure 21 and supply liquid to the cleaning component 20, ensuring that the liquid does not flow onto the ground and that the cleaning component 20 can also be wetted by the liquid, so that the cleaning component 20 can effectively perform wet cleaning work on the ground.

[0059] Furthermore, by connecting the liquid outlet 31 to the drive component 41 and using the first clearance hole 11 to realize the movement and installation of the drive component 41, the structure of the cleaning equipment is simplified, additional connecting parts and complex installation steps are reduced, manufacturing costs and assembly difficulty are reduced, and it is also convenient for later maintenance and repair, thus improving the maintainability of the product.

[0060] The flow guiding structure 21 includes at least one first through hole 211. The cleaning assembly 20 includes a tray 22 and a flexible cleaning element 23. The tray 22 is connected to the drive shaft 43, and at least one first through hole 211 is disposed through the tray 22 along the height direction of the main body 10. The flexible cleaning element 23 is disposed on the surface of the tray 22 away from the main body 10. When the cleaning assembly 20 is in the retracted state, the first through hole 211 has a second projected outer contour on the liquid outlet 31 along the height direction of the main body 10; when the cleaning assembly 20 is in the expanded state, the first through hole 211 has a third projected outer contour on the liquid outlet 31 along the height direction of the main body 10. The second and third projected outer contours have overlapping areas (e.g., ...). Figure 6 (The shaded area in the image), outlet 311 is located within the overlapping area.

[0061] Liquid flowing from outlet 311 can pass through the first through-hole 211 and flow onto the flexible cleaning component 23, wetting it. The flexible cleaning component 23 can then contact the ground for wet cleaning. During the movement of the cleaning component 20 between its retracted and expanded states, liquid accurately enters the first through-hole 211 and flows onto the flexible cleaning component 23, preventing it from flowing to rigid structural areas on the tray 22 (such as the area between the first through-holes 211, or the area between the first through-holes 211 and the outer edge of the tray 22) and splashing onto the ground. This effectively prevents contamination of the ground already cleaned by the cleaning equipment, achieving ideal cleaning results and a better user experience. The spaced arrangement of multiple first through-holes 211 increases the structural strength of the tray 22, preventing damage and improving the reliability of the cleaning component 20, thus extending the service life of the cleaning equipment.

[0062] Specifically, the tray 22 includes a tray body 221 and an outer ring portion 222. The outer ring portion 222 surrounds the outer periphery of the tray body 221. Along the height direction of the body 10, a plurality of second through holes 223 are provided through the outer ring portion 222, and the plurality of second through holes 223 are arranged at intervals along the circumference of the outer ring portion 222. The outer ring portion 222 includes a soft rubber structural component. In some embodiments, at least one other water outlet 311 may be provided on the liquid outlet 31 corresponding to the second through hole 223 on the outer ring portion 222, so that water from the at least one other water outlet 311 can be poured onto the flexible cleaning component 23 through the second through hole 223. Since the at least one other water outlet 311 can move synchronously with the second through hole 223 as the cleaning component 20 moves, water splashing is less likely to occur when water is supplied to the flexible cleaning component 23 through the other water outlet 311 and the second through hole 223 during the movement of the cleaning component 20.

[0063] Alternatively, the flow guiding structure 21 may include an annular groove and a first through hole 211 disposed at the bottom of the annular groove. The annular groove extends circumferentially along the tray 22. Liquid flows into the annular groove from the outlet 311 and then flows to the flexible cleaning component 23 through the first through hole 211. In this way, no matter how the cleaning component 20 rotates, it can be ensured that the outlet 311 drips water into the annular groove. This arrangement can further prevent liquid from splashing onto the ground.

[0064] The flexible cleaning component 23 includes mops, cleaning brushes, etc., but this embodiment does not limit it to a single component.

[0065] When the cleaning component 20 is in any of the following positions—retracted, expanded, or a combination of both—the outlet 311 remains aligned with the first through hole 211. Liquid flowing from the outlet 311 is directed onto the first through hole 211, effectively preventing it from overflowing and spilling onto surfaces such as the floor, walls, or furniture (e.g., the bottom of cabinets, table legs). During the movement of the cleaning component 20 between the retracted and expanded states, no liquid will spill onto the floor, effectively preventing contamination of areas already cleaned by the cleaning component 20 and ensuring better cleaning results.

[0066] In one embodiment, the flow guiding structure 21 has a length L1 along a first clockwise direction. When the cleaning component 20 moves from an inward state to an outward state or from an outward state to an inward state, the arc distance by which the flow guiding structure 21 moves along the first clockwise direction with the cleaning component 20 is L2, where L1 is greater than L2. It can be understood that the length L1 of the flow guiding structure 21 along the first clockwise direction is the length of the first through hole 211.

[0067] During the first rotation of the cleaning component 20, the position of the water outlet 311 changes relative to the flow guide structure 21. To ensure that liquid does not flow onto the rigid structure of the tray 22, the length of the first through hole 211 is greater than the arc distance by which the flow guide structure 21 moves with the rotation of the cleaning component 20. This ensures that the water outlet 311 always aligns with the first through hole 211 on the tray 22, and the liquid flowing from the water outlet 311 always passes through the first through hole 211 to the flexible cleaning component 23. Regardless of whether the cleaning component 20 is in the retracted state, the expanded state, or any position between the retracted and expanded states, the water outlet 311 is always aligned with the first through hole 211, effectively preventing liquid from splashing onto the ground. If the length of the first through hole 211 is not greater than the arc distance that the guide structure 21 moves when the cleaning component 20 rotates, during the first rotation of the cleaning component 20, the liquid may flow to the area between the first through holes 211, and the liquid may splash outside the cleaning component 20 and flow to the ground, affecting the cleaning effect of the cleaning equipment and resulting in a poor user experience.

[0068] The liquid outlet component 31 includes a sealing plate 310. A second clearance hole 312 is provided on the sealing plate 310. The second clearance hole 312 is opposite to and communicates with the first clearance hole 11. Along the height direction of the main body 10, the projected outer contour of the first clearance hole 11 is located within the projected outer contour of the sealing plate 310. A drive shaft 43 passes through the first clearance hole 11 and the second clearance hole 312 and is connected to the cleaning component 20. The water outlet 311 is located on one side of the second clearance hole 312 and is spaced apart from it. The drive shaft 43 passes through the first clearance hole 11 and the second clearance hole 312 and is connected to the cleaning component 20. The cleaning component 20 and the sealing plate 310 can move synchronously under the drive of the drive shaft 43, ensuring that the water outlet 311 on the sealing plate 310 is always in communication with the first through hole 211.

[0069] Specifically, while the driving component 41 drives the cleaning component 20 to perform a first rotational movement relative to the main body 10 via the transmission shaft 43, the cleaning component 20, under the action of the frictional torque of the ground, drives the transmission shaft 43 to move relative to the main body 10, and the driving component 41 also moves relative to the main body 10 along with the transmission shaft 43. In this embodiment, the first clockwise direction is clockwise, and the second clockwise direction is clockwise. When the cleaning component 20 performs the first rotational movement in the clockwise direction, it is subjected to a frictional torque in the counterclockwise direction, causing the cleaning component 20 to drive the driving component 40 to move in the counterclockwise direction to an outward expansion state. During the clockwise rotation of the cleaning component 20, the ground applies a clockwise frictional force to the cleaning component 20, causing the cleaning component 20 to move in the outward expansion state relative to the main body 10 and causing the water outlet 311 on the liquid outlet 31 to also move in the counterclockwise direction relative to the main body 10. Therefore, during the movement of the cleaning component 20 from the retracted state to the outward expansion state, both the guide structure 21 and the outlet 311 move counterclockwise relative to the main body 10. The outlet 311 is always aligned with the guide structure 21, and the liquid flowing out of the outlet 311 can flow into the guide structure 21, ensuring that the liquid does not fall onto the ground during the outward expansion of the cleaning component 20. When the cleaning component 20 rotates counterclockwise, it is subjected to a frictional torque in the clockwise direction, causing the cleaning component 20 to drive the drive shaft 43 to move clockwise to the retracted state. The liquid outlet 31 is connected to the drive shaft 43 and can move clockwise or counterclockwise under the drive of the drive shaft 43. During the process of the drive shaft 43 driving the cleaning component 20 to rotate counterclockwise, the ground applies a frictional force in the clockwise direction to the cleaning component 20, causing the cleaning component 20 to move inward relative to the main body 10 and causing the outlet 311 on the liquid outlet 31 to also move clockwise relative to the main body 10. Therefore, during the process of the cleaning component 20 moving from the outward expansion state to the inward contraction state, both the guide structure 21 and the water outlet 311 move clockwise relative to the main body 10. The water outlet 311 can always be aligned with the guide structure 21, and the liquid flowing out of the water outlet 311 can flow into the guide structure 21, ensuring that the liquid will not fall on the ground during the inward contraction process of the cleaning component 20, and ensuring that the cleaning equipment achieves a better cleaning effect.

[0070] The cleaning component 20 can move between an inward and outward state under the action of frictional torque while rotating. The cleaning component 20 can move automatically relative to the main body 10 without the need for additional power actuators, thus reducing the complexity and cost of the cleaning equipment.

[0071] The cleaning component 20 can rotate in a second clockwise direction to move from one of an inward or outward state to the other. The drive component 40 and the sealing plate 310 can also rotate around a first axis under the drive of the cleaning component. The first clockwise direction is the same as or opposite to the second clockwise direction. The second clearance hole 312 is spaced apart from the first axis along the radial direction of the drive shaft 43. The cleaning device also includes a connecting component 42. Along the radial direction of the drive shaft 43, the connecting component 42 is connected to the main body 10 and located on the side of the drive component 41 away from the second clearance hole 312. The sealing plate 310 and the drive component 41 are respectively connected to the connecting component 42, and both the sealing plate 310 and the drive component 41 can rotate relative to the connecting component 42 under the drive of the cleaning component.

[0072] In this embodiment, the sealing plate 310 has a circular structure, and a third clearance hole 314 is provided through the sealing plate 310. The third clearance hole 314 is coaxial with the sealing plate 310. The connecting component 42 at least partially penetrates the main body 10 and the third clearance hole 314. The third clearance hole 314 and the connecting component 42 are clearance-fitted and rotatably connected by a pin, so that the sealing plate 310 can rotate around the connecting component 42 under the drive of the transmission shaft 43. A groove 13 is provided on the side of the main body 10 near the sealing plate 310. The sealing plate 310 is embedded in the groove 13 and can rotate relative to the inner wall surface of the groove 13, thereby improving the sealing effect of the sealing plate 310 on the first clearance hole 11.

[0073] The drive component 41 is connected to the connecting assembly 42 and can rotate relative to the connecting assembly 42. The connecting assembly 42 ensures that the drive component 41 can be stably mounted on the main body 10 and also ensures that the drive component 41 can move relative to the main body 10, thus ensuring the stability of the cleaning component 20 during movement. The drive shaft 43 is connected to the sealing plate 310 through the second clearance hole 312, allowing the sealing plate 310 to move relative to the main body 10 as the drive shaft 43 moves. The sealing plate 310 is connected to the connecting assembly 42 and can rotate relative to the connecting assembly 42. The connecting assembly 42 ensures that the sealing plate 310 can be stably mounted on the main body 10 and also ensures that the sealing plate 310 can rotate relative to the main body 10.

[0074] The first clearance hole 11 can be configured as an arc-shaped strip hole, adapted to the clockwise movement of the cleaning component 20 between its retracted and expanded states. Under the action of frictional torque, the cleaning component 20 drives the transmission shaft 43 to move smoothly within the arc-shaped strip hole, effectively reducing interference between the transmission shaft 43 and the main body 10, ensuring that the cleaning component 20 can flexibly adjust its angle, improving the cleaning effect and reducing cleaning dead angles. The connecting component 42 installs the sealing plate 310 and the driving component 41 onto the main body 10. While the driving component 41 drives the sealing plate 310 to rotate relative to the main body 10, the connecting component 42 can improve the stability of the cleaning component 20 during movement, allowing the liquid to accurately flow through the guide structure 21 onto the flexible cleaning component 23, preventing the liquid from flowing onto the ground, and improving the cleaning ability of the cleaning equipment.

[0075] Alternatively, the first clearance hole 11 can also be configured as a linear strip hole, and the drive shaft 43 moves along the linear strip hole to realize the inward and outward movement of the cleaning component 20.

[0076] The connecting component 42 includes a connecting seat 421 and a connecting shaft 422. Along the height direction of the main body 10, the connecting seat 421 is located on the side of the main body 10 away from the cleaning component 20 and is fixedly connected to the main body 10, forming an installation space between the connecting seat 421 and the main body 10. Along the height direction of the main body 10, one end of the connecting shaft 422 is fixedly connected to the connecting seat 421, and the other end of the connecting shaft 422 extends from the installation space to the side of the main body 10 near the cleaning component 20. The driving component 41 is connected to the portion of the connecting shaft 422 located in the installation space and can perform a second rotational movement around the axis of the connecting shaft 422. Along the height direction of the main body 10, the sealing plate 310 is located on the side of the main body 10 near the cleaning component 20, and the sealing plate 310 is rotatably connected to the side of the connecting shaft 422 near the cleaning component 20.

[0077] The connecting seat 421 is fixedly connected to the main body 10, providing a stable mounting base for the connecting shaft 422 and the drive component 41. The connecting seat 421 can stably connect the drive component 41, the connecting shaft 422, and the sealing plate 310 to the main body 10, ensuring that the drive component 40, the cleaning component 20, and the sealing plate 310 maintain a relatively stable state during the operation of the cleaning equipment. This ensures that the sealing plate 310 and the cleaning component 20 can move synchronously. During the movement of the cleaning component 20, the accuracy of the corresponding positional relationship between the outlet 311 and the flow guiding structure 21 can be improved, thereby enhancing the stability and reliability of the overall structure of the cleaning equipment.

[0078] The drive component 41 includes a motor and a tooth box. The motor is connected to the tooth box for transmission. A tooth box hole is provided on the outside of the tooth box. The drive shaft 43 extends out of the tooth box hole and is connected to the cleaning component 20.

[0079] An outer flange 4221 is provided on the side of the connecting shaft 422 near the cleaning component 20. The third clearance hole 314 of the sealing plate 310 is sleeved on the side of the outer flange 4221 near the cleaning component 20 and is clearance-fitted with the connecting shaft 422. The pin passes through the third clearance hole 314 and is connected to the connecting shaft 422. An outer flange is also provided on the side of the pin away from the sealing plate 310 to restrict the sealing plate 310 on the connecting shaft 422. Finally, the sealing plate 310 is confined in the groove 13 and can rotate around the connecting component 42 under the drive of the transmission shaft 43.

[0080] During the movement of the cleaning component 20, the cleaning component 20 drives the drive shaft 43 to move. The drive shaft 43 drives the sealing plate 310 and the drive component 41 to move relative to the main body 10. The connecting shaft 422 is rotatably connected to the drive component 41 to ensure the smooth movement of the drive component 41. The connecting shaft 422 is rotatably connected to the sealing plate 310 to ensure the smooth rotation of the sealing plate 310.

[0081] In one embodiment, a limiting structure 411 is also provided between the driving component 41 and the sealing plate 310. The limiting structure 411 is located on one side of the drive shaft 43 along its own radial direction and is opposite to the first clearance hole 11. Along the radial direction of the drive shaft 43, the limiting structure 411 is used to keep the sealing plate 310 stationary relative to the drive shaft 43. When the cleaning component 20 moves from one of the retracted state and the outward expansion state to the other, the limiting structure 411 can ensure that the sealing plate 310 remains stationary relative to the driving component 41, so that the sealing plate 310 can move synchronously with the driving component 41. This ensures that the outlet 311 can always be aligned with the first through hole 211, improves the positional accuracy between the outlet 311 and the first through hole 211, and effectively prevents the outlet 311 from shifting from the first through hole 211. In addition, the limiting structure 411 can also strengthen the connection strength between the sealing plate 310 and the driving component 41, and improve the reliability and stability of the cleaning equipment.

[0082] The limiting structure 411 includes a first limiting post 4111 and a second limiting post 4112. Along the height direction of the main body 10, the first limiting post 4111 is located on the side of the driving component 41 near the sealing plate 310 and is opposite to the sealing plate 310. A first limiting hole is provided within the first limiting post 4111 along the height direction of the main body 10. Along the height direction of the main body 10, the second limiting post 4112 is located on the side of the sealing plate 310 near the driving component 41. The second limiting post 4112 is adapted to the first limiting hole, and at least partially inserted into the first limiting hole. The first limiting post 4111 is fixed to the driving component 41, and the second limiting post 4112 is fixed to the sealing plate 310. Through plugging and unplugging, the two can stably maintain their relative positional relationship during the second rotational movement of the cleaning component, allowing the sealing plate 310 to move synchronously with the driving component 41. The sealing plate 310 and the driving component 41 are limited by the cooperation between the first limiting hole on the first limiting post 4111 and the second limiting post 4112. The structure is simple, the assembly difficulty is reduced, and the reliability of the limiting structure 411 is improved.

[0083] In one embodiment, a liquid outlet connector 313 is provided on the side of the liquid outlet component 31 near the main body 10, and the liquid outlet connector 313 is connected to the water outlet 311. The liquid supply component includes a water tank and a flexible water outlet pipe 32. The flexible water outlet pipe 32 connects the water tank and the liquid outlet connector 313, and the end of the flexible water outlet pipe 32 near the liquid outlet connector 313 moves with the liquid outlet component 31. The length of the flexible water outlet pipe 32 is greater than the distance between the water tank and the water outlet 311. After the liquid flows out of the water tank, it enters the flexible water outlet pipe 32, then flows into the liquid outlet connector 313 and flows out from the water outlet 311, forming a stable liquid delivery channel. This ensures that the liquid can reliably and continuously flow onto the cleaning component 20, ensuring that the cleaning component 20 can maintain a suitable level of moisture and achieve a good cleaning effect. During the movement of the liquid outlet component 31, the flexible water outlet pipe 32 can bend and twist to a certain extent, which can well adapt to the movement of the liquid outlet component 31 and follow the movement of the liquid outlet component 31. This effectively prevents the flexible water outlet pipe 32 from breaking, ensuring that the liquid can be continuously and stably delivered from the water tank to the liquid outlet component 31 and sprayed onto the cleaning component 20 through the water outlet 311. Specifically, the liquid supply component also includes a water pump, which is installed between the water tank and the flexible water outlet pipe 32. The water pump draws the liquid in the water tank to the water outlet 311.

[0084] Among them, such as Figure 4As shown, at least one of the main body 10 and the drive component 41 is provided with a limiting groove 12, and the flexible water outlet pipe 32 is laid in the limiting groove 12. The limiting groove 12 can effectively fix the position of the flexible water outlet pipe 32, preventing the flexible water outlet pipe 32 from moving or shaking randomly during the movement of the cleaning component 20. The limiting groove 12 ensures that the flexible water outlet pipe 32 always stays in the proper position, avoiding friction, collision or entanglement with other components, thereby ensuring that the cleaning equipment achieves a good cleaning effect.

[0085] 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. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
