Description

Technical Field

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

[0002] Currently, cleaning robots include robotic vacuum cleaners, floor mopping robots (robots with mopping functions but no sweeping function), dual-disc robotic vacuum cleaners, and floor scrubbers. Some cleaning robots are equipped with a mop, which allows them to perform wet cleaning by contacting the surface to be cleaned (such as the floor or tabletop) with the mop in mopping mode. During the cleaning process, the mop can swing relative to the main body of the cleaning robot to reduce cleaning dead spots and improve the cleaning effect.

[0003] During the wet cleaning process, the cleaning device uses a water outlet to soak the mop with liquid from the water tank. However, as the mop moves between its retracted and expanded positions to clean the environment, liquid can easily splash outside the mop and onto the floor, walls, furniture, and other objects, 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 easily splashes outside the mop and flows onto objects such as the floor, walls, and furniture during the movement of the mop between the retracted and expanded states.

The plug-in protrusion is adapted to the plug-in hole and is inserted into the plug-in hole, thereby communicating at least one second inlet with at least one outlet.

[0019] Alternatively, the cleaning component may be provided with a flow guiding structure, and a connecting component may be provided between the flow guiding structure and at least one of the outlets, the connecting component connecting the flow guiding structure and at least one of the outlets.

[0020] Furthermore, a stop structure is provided between the device body and the connecting member, the stop structure being used to stop the connecting member in the second state.

During the movement of the cleaning component from one of an inward-facing state to the other, since the drive shaft component moves with the cleaning component between the inward-facing and outward-facing states, the outlet also moves with the drive shaft component and the cleaning component. Therefore, the position of the outlet supplying fluid to the cleaning component relative to the cleaning component remains constant, and the fluid flowing from the outlet can flow directly onto the cleaning component without flowing outside the cleaning component. Especially when the fluid includes liquid, this prevents liquid from splashing onto the floor, walls, furniture, etc. Attached Figure Description

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0053] The mop of the cleaning equipment can move between an inward-retracting state and an outward-expanding state to switch positions for edge cleaning or normal cleaning of the surface to be cleaned. During the movement of the mop from one of these states to the other, liquid can easily fall onto the mop holder 21, causing it to collide with the holder and splash onto the floor, walls, furniture (such as the bottom of cabinets and table legs), etc. While the splashed liquid can be cleaned through secondary cleaning, it increases the cleaning burden on the equipment and reduces cleaning efficiency. If walls are constantly splashed with water, it not only reduces the aesthetics of the surface but also affects the durability of the wall surface, potentially leading to peeling over time. Secondly, some furniture is prone to rotting after being soaked in water for a long time, reducing its lifespan and resulting in a poor user experience. Furthermore, it can reduce the amount of liquid received by the mop, lowering its moisture content.

[0054] To address the aforementioned problems, the first embodiment of this utility model provides a cleaning device to solve the issue that liquid easily splashes outside the mop and flows onto objects such as the floor, walls, and furniture during the movement of the mop between its retracted and expanded states. Please see [link to relevant documentation]. Figures 1 to 11 The cleaning equipment includes a device body 10, a cleaning component 20, a drive component 30, and a fluid supply component 40.

[0055] The cleaning component 20 is located at the bottom of the device body 10 and has an inward-retracted state and an outward-expanded state. When the cleaning component 20 is in the outward-expanded state, the part outside the edge contour of the device body 10 is larger than the part outside the edge contour of the device body 10 when the cleaning component 20 is in the inward-retracted state, so that when the cleaning component 20 is in the outward-expanded state, it can clean the corner blind areas of the surface to be cleaned (such as the ground, table, wall, etc.).

[0056] The drive assembly 30 includes a drive component 31 and a transmission shaft component 32. The drive component 31 is located on the device body 10, and the transmission shaft component 32 is connected between the drive component 31 and the cleaning assembly 20. The drive component 31 is at least used to drive the transmission shaft component 32 to move the cleaning assembly 20 in a first clockwise direction (e.g., ...). Figure 1 Rotating in the direction indicated by the middle arrow S, the first clockwise direction is either clockwise or counterclockwise. The drive shaft component 32 can move between an inward and outward state with the cleaning assembly 20.

[0057] Please see Figures 4 to 7 The fluid supply assembly 40 includes at least one outlet 401 disposed on the drive shaft component 32. The fluid supply assembly 40 is used to direct fluid along the at least one outlet 401 onto the cleaning assembly 20 to wet the cleaning assembly 20. Because the outlet 401, which sprays or directs fluid onto the cleaning assembly 20, can move with the movement of the drive shaft component 32 and the cleaning assembly 20, the position of the outlet 401 relative to the cleaning assembly 20 remains constant. When the fluid includes liquid, it is less likely to splash outside the cleaning assembly 20, preventing the floor, walls, and furniture from being constantly wetted by liquid, improving the cleaning efficiency of the cleaning assembly 20, and avoiding unnecessary damage to the walls and furniture.

[0058] The fluid supplied by the fluid supply component 40 may include clean water or a mixture of clean water and other substances that can improve the cleaning effect of the cleaning component 20. When the fluid is a liquid, it can be cold water, warm water (e.g., water with a temperature below 38 degrees Celsius), or hot water (e.g., water with a temperature above 38 degrees Celsius or even above 50 degrees Celsius). When the fluid includes at least one of warm water and hot water, in addition to wetting the cleaning component 20, it can also improve the cleaning component 20's ability to dissolve stubborn stains (such as grease), thereby better cleaning stubborn stains. Secondly, because the hot water temperature is high, it can also effectively kill bacteria and mites on the cleaning component 20, achieving the purpose of disinfection and sterilization. As can be seen, in this embodiment, the cleaning device includes a device body 10, a cleaning component 20, a drive component 30, and a fluid supply component 40. At least one outlet 401 of the fluid supply component 40 is provided on the drive shaft component 32, so that the fluid supply component 40 can flow fluid through at least one outlet 401 to the cleaning component 20 to wet the cleaning component 20. The fluid supplied by the fluid supply component 40 may include liquids such as cold water and hot water. During the movement of the cleaning component 20 from one of the retracted state and the outward expansion state to the other, since the drive shaft component 32 can move with the cleaning component 20 between the retracted and outward expansion states, the outlet 401 will also move with the drive shaft component 32 and the cleaning component 20. Therefore, the position of the outlet 401 supplying fluid to the cleaning component 20 relative to the cleaning component 20 remains constant, and the fluid flowing out of the outlet 401 can flow directly onto the cleaning component 20 without flowing outside the cleaning component 20. Especially when the fluid includes liquids, this prevents liquid from splashing onto the floor, walls, furniture, etc.

[0059] like Figures 4 to 7 As shown, in this embodiment, the drive shaft component 32 includes a shaft body 321 and a connecting member 322. The shaft body 321 is connected between the drive component 31 and the cleaning component 20. At least one outlet 401 is provided on the shaft body 321. The shaft body 321 can drive the cleaning component 20 to rotate under the drive of the drive component 31 (for ease of description and distinction, the self-rotation motion of the shaft body 321 is referred to as the first rotational motion below), and can move with the cleaning component 20 between an inward retracted state and an outward expansion state. During this process, the outlets 401 can all move with the movement of the shaft body 321, and the fluid (especially liquid) coming out of the outlets 401 is less likely to spill onto walls, furniture, or other objects.

[0060] The connecting member 322 is connected to the shaft body 321 and located between the drive component 31 and the cleaning component 20. The connecting member 322 is provided with a first inlet 220, which connects to the fluid supply component 40 and at least one outlet 401. Thus, the fluid provided by the fluid supply component 40 can flow along the first inlet 220 to at least one outlet 401, and then be supplied to and wet the cleaning component 20.

[0061] To ensure that the connecting member 322 can transmit fluid from the fluid supply component 40 to at least one outlet 401 after being connected to the fluid supply component 40 via a pipe, hose, etc., without interfering with the rotational movement of the shaft body 321, the connecting member 322 in this embodiment has a first state of movement relative to the device body 10 and a second state of being stationary relative to the device body 10.

[0062] When the connecting member 322 is in the first state, it can move between an inward and outward state with the cleaning assembly 20. When the cleaning assembly 20 is in either the inward or outward state, the connecting member 322 remains in the second state. Furthermore, when the connecting member 322 is in the second state, the shaft body 321 can rotate relative to the connecting member 322 under the drive of the drive component 31. Therefore, when the cleaning assembly 20 needs to switch between the inward and outward states, the connecting member 322 will switch from the second state to the first state and swing with the cleaning assembly 20. When the cleaning assembly 20 is performing cleaning work in either the inward or outward state, the connecting member 322 switches from the first state to the second state, thereby ensuring that the cleaning assembly 20 can operate stably and reliably under the drive of the shaft body 321.

[0063] As can be seen, this embodiment constructs a transmission shaft component 32 capable of driving the cleaning component 20 to perform a first rotational motion by connecting a connecting member 322 to the shaft body 321. This improves the structural compactness of the transmission shaft component 32 while ensuring that the fluid provided by the fluid supply component 40 is stably and continuously transmitted to at least one outlet 401 provided on the shaft body 321. Furthermore, when the connecting member 322 is connected to the fluid supply component 40 through a connecting pipe, the connection pipe can be prevented from tangling or breaking during the first rotational motion of the cleaning component 20 driven by the shaft body 321.

[0064] In some embodiments, when the fluid includes liquid, a water receiving trough can be arranged around the outer periphery of the drive shaft component 32 along its own axial direction. The water receiving trough is connected to at least one outlet 401. The fluid supply component 40 can be connected to the water receiving trough via a connecting pipe or a water outlet (the end of the connecting pipe away from the fluid supply component 40 can be placed in the water receiving trough), so that the liquid flows into the water receiving trough through the connecting pipe or the water outlet, and then flows to the cleaning component 20 from at least one outlet 401. A cover can also be provided on the water receiving trough. The cover is rotatably connected to the water receiving trough. When the water receiving trough rotates with the drive shaft component 32, the cover is stationary relative to the equipment body 10. The cover is connected to the fluid supply component 40 through a connecting pipe, etc. The fluid enters the guiding space formed by the cover and the water receiving trough, and then flows to the cleaning component 20 through at least one outlet 401. This method can ensure that the fluid will not spread or splash into the inside or outside of the equipment body 10, improving the safety and reliability of the cleaning equipment. The above method can also improve the connection reliability between the fluid supply component 40 and the drive shaft component 32 while achieving stable and continuous fluid transmission.

[0065] like Figure 4 and Figure 7 As shown, the connecting member 322 includes a cylindrical structure. A first through hole 221 is provided through the connecting member 322 along the axial direction of the shaft body 321. The first through hole 221 is fitted onto the outer periphery of the shaft body 321 and forms a mounting groove 222 with the shaft body 321. The mounting groove 222 connects the first inlet 220 and at least one outlet 401. Therefore, in this embodiment, the cylindrical connecting member 322 is fitted onto the outer periphery of the shaft body 321 through the first through hole 221, forming a mounting groove 222 that connects the first inlet 220 and at least one outlet 401. During the first rotational movement, the shaft body 321 rotates relative to the connecting member 322. The mounting groove 222 dynamically connects the first inlet 220 and at least one outlet 401, enabling the fluid to be dynamically and continuously guided to at least one outlet 401 through the mounting groove 222, and ensuring the overall stability and reliability of the transmission shaft component 32.

[0066] In this embodiment, the outlet 401 includes at least two outlets 401 arranged circumferentially along the shaft body 321, thereby efficiently guiding fluid to the cleaning assembly 20 through the at least two outlets 401.

[0067] like Figure 4 and Figure 7As shown, to improve the sealing of the mounting groove 222 and prevent fluid overflow, when the fluid consists only of liquid, the drive shaft component 32 in this embodiment may also include a first seal 323. Along the axial direction of the shaft body 321, the first seal 323 is disposed at the bottom of the mounting groove 222 near the cleaning component 20 and can rotate with the shaft body 321 relative to the connecting member 322. The first seal 323 is used to seal the gap between the connecting member 322 and the shaft body 321 located at the bottom of the mounting groove 222. Therefore, after the liquid enters the mounting groove 222 from the first inlet 220, regardless of whether the shaft body 321 rotates, the first seal 323 can ensure that the liquid will not overflow from the gap at the bottom of the mounting groove 222 into the external space of the drive shaft component 32.

[0068] In this embodiment, the bottom of the mounting groove 222 near the cleaning component 20 and the top of the mounting groove near the drive component 31 are both configured as sealed structures with walls. In this case, even if there is a gap between the connecting member 322 and the shaft body 321, the fluid is not likely to leak to the outside of the drive shaft component 32, thereby protecting the internal components of the device body 10 from being wetted by the fluid and causing malfunctions or damage.

[0069] In this embodiment, regardless of whether the side of the mounting groove 222 near the drive component 31 is an open structure or a sealed enclosure structure with a covering function, the drive shaft component 32 in this embodiment may also include a second seal 324. Along the axial direction of the shaft body 321, the second seal 324 is disposed on the side of the mounting groove 222 near the drive component 31 and can rotate with the shaft body 321 relative to the connecting member 322. The second seal 324 is used to seal the gap between the connecting member 322 and the shaft body 321 located on the side of the mounting groove 222 near the drive component 31. Since the second seal 324 seals the gap between the connecting member 322 and the shaft body 321 located on the upper side of the mounting groove 222, it ensures that fluid will not diffuse into the device body 10 from the gap or openness on the upper side of the mounting groove 222.

[0070] Of course, in this embodiment, along the axial direction of the shaft body 321, a first seal 323 can be provided at the bottom of the mounting groove 222, and a second seal 324 can be provided on the side of the mounting groove 222 near the drive component 31. This seals the gaps in each area of ​​the mounting groove 222, effectively preventing fluid from overflowing, improving fluid transmission efficiency and utilization, and protecting external components of the drive shaft component 32. Furthermore, when installing the first seal 323 and the second seal 324, it is only necessary to ensure that there is an installation gap between them so that the mounting groove 222 can connect the first inlet 220 and at least one outlet 401, making assembly simple and convenient.

[0071] In this embodiment, both the first seal 323 and the second seal 324 can be flexible rubber sealing structures. When the connecting member 322 is in the second state, the first seal 323 and the second seal 324 can remain relatively stationary with respect to the connecting member 322. The shaft body 321 can then overcome the frictional force between itself and the first seal 323 and the second seal 324 to perform a first rotational movement relative to the connecting member 322. Alternatively, in this embodiment, the first seal 323 and the second seal 324 can also perform a first rotational movement with the shaft body 321. Regardless of whether the first seal 323 and the second seal 324 perform a first rotational movement, the gap between the connecting member 322 and the shaft body 321 can be dynamically sealed to prevent fluid leakage.

[0072] Among them, such as Figure 4 and Figure 8 As shown, the cleaning assembly 20 includes a support 21 and a flexible cleaning element 22. The support 21 is connected to the shaft body 321, and the support 21 is provided with a flow guiding structure 210, which communicates with at least one outlet 401. The flow guiding structure 210 can guide fluid from at least one outlet 401 to the flexible cleaning element 22, thereby achieving wetting of the flexible cleaning element 22. The flow path of the fluid when the flow guiding structure 210 guides the fluid to the flexible cleaning element 22 is shown in the AA cross-sectional view. Figure 4 The path indicated by the middle arrow. Along the axial direction of the shaft body 321, the flexible cleaning element 22 is disposed on the side of the support 21 away from the shaft body 321, so that the flexible cleaning element 22 can clean the surface to be cleaned. Among them, since the flow guiding structure 210 is disposed on the support 21 and the outlet 401 is located on the shaft body 321, the flow guiding structure 210 can also move with the movement of the support 21. The positions of the flow guiding structure 210 and at least one outlet 401 always remain unchanged. Whether the flow guiding structure 210 and at least one outlet 401 are connected by a connecting pipe or directly, the fluid can be reliably guided from the outlet 401 to the flow guiding structure 210. In this process, when the fluid contains liquid, the liquid is not likely to spill to other positions of the support 21 and collide with the support 21 and splash out.

[0073] In some embodiments, the guide structure 210 may not be required on the bracket 21, and at least one outlet 401 on the shaft body 321 may be directly aligned with the flexible cleaning component 22 to achieve wetting of the flexible cleaning component 22.

[0074] In some embodiments, the flow guiding structure 210 can be a series of pipe structures laid on the support 21, with the end opening of the pipe structure aligned with the flexible cleaning element 22, so that the fluid can flow along the pipe structure to the opening and then to the flexible cleaning element 22.

[0075] In this embodiment, when the fluid includes a liquid, the combination Figure 4and Figure 8 It is understood that the flow guiding structure 210 includes a first groove 101 and a second through hole 102. Along the axial direction of the shaft body 321, the first groove 101 is disposed on the side of the bracket 21 near the shaft body 321 and communicates with at least one outlet 401. The second through hole 102 is disposed through the bracket 21 and communicates with the first groove 101. In this embodiment, the first groove 101 and the second through hole 102 are provided on the bracket 21 to serve as the flow guiding structure 210. Liquid from at least one outlet 401 flows into the first groove 101, then flows from the first groove 101 to the second through hole 102, and then the liquid flowing out through the second through hole 102 wets the flexible cleaning component 22. At the same time, the provision of the first groove 101 and the second through hole 102 does not increase the volume and weight of the bracket 21, thereby reducing the driving pressure of the drive component 31 on the bracket 21. If the drive component 31 includes a motor 312, it can also avoid the motor 312 from overloading or stalling, thus improving the service life of the drive component 31.

[0076] In some embodiments, the flow guiding structure 210 may also include only the second through hole 102, which can be directly connected to at least one outlet 401.

[0077] In some embodiments, the flow guiding structure 210 includes a flow guiding cavity and a second through hole 102. The flow guiding cavity is disposed within the support 21 and communicates with at least one outlet 401. The second through hole 102 is disposed through the support 21 and communicates with the flow guiding cavity. The flow guiding structure 210 including the flow guiding cavity can more efficiently and reliably transfer fluid to the second through hole 102, avoiding fluid loss along the way. The flow guiding cavity and the second through hole 102 can be connected by a connecting pipe, or the second through hole 102 can be directly disposed at the bottom of the flow guiding cavity.

[0078] Among them, such as Figure 4 and Figure 8 As shown, when the flow guiding structure 210 includes a flow guiding cavity and a second through hole 102, the bracket 21 in this embodiment may specifically include a cover and a tray 212. The cover is connected to the shaft body 321 and is provided with at least one second inlet 110. The at least one second inlet 110 communicates with at least one outlet 401. Along the axial direction of the shaft body 321, the tray 212 is disposed on the side of the cover away from the shaft body 321 and surrounds the cover to form a flow guiding cavity. The flow guiding cavity communicates with the second inlet 110, and the second through hole 102 is disposed through the tray 212 and communicates with the flow guiding cavity.

[0079] Fluid exiting at least one outlet 401 enters the guide cavity through at least one second inlet 110 on the cover, and then flows along the guide cavity and the second through hole 102 to the flexible cleaning component 22. This process achieves fully enclosed fluid transmission, preventing fluid loss and overflow, and further ensuring that the fluid will not splash onto the ground, walls, or tabletops before reaching the flexible cleaning component 22. Furthermore, in this embodiment, after assembling the cover and tray 212, the corresponding guide cavity is obtained. Then, the cover is connected to the shaft body 321, and the second inlet 110 is connected to the outlet 401. The overall structure is assembled efficiently and conveniently. The second inlet 110 and outlet 401 can be directly connected or connected through a connecting pipe; this embodiment does not impose a limitation on this.

[0080] In some implementations, such as Figure 8 As shown, the tray 212 may include a main body 121 and a flexible outer ring 122 located on the outer periphery of the main body 121. A first groove 101 may be provided on the main body 121, and a second through hole 102 may be provided on at least one of the main body 121 and the flexible outer ring 122. Furthermore, along the radial direction of the shaft body 321, a cover is provided covering the main body 121, and the flexible outer ring 122 is located on the outer periphery of the main body 121 and offset from the cover. Thus, when the bracket 21 is composed of the tray 212 and the cover, the flexible outer ring 122 is located at the outermost edge of the bracket 21, which can reduce the impact force of the bracket 21 on walls, furniture, etc., thereby avoiding damage to walls, furniture, and the bracket 21 itself, and improving the service life of the bracket 21.

[0081] like Figure 8 As shown, in some embodiments, along the axial direction of the shaft body 321, a first groove 101 is provided on the side of the tray 212 near the cover. The inner wall of the first groove 101 and the cover form a flow guiding cavity, and the second through hole 102 communicates with the first groove 101. That is to say, in this embodiment, the first groove 101 is opened on the tray 212. After the cover is placed on the tray 212, an installation cavity can be obtained, reducing the difficulty of opening the installation cavity on the bracket 21. Of course, in this embodiment, the first groove 101 can also be opened on the side of the cover near the tray 212, or the first groove 101 can be provided on both the side of the cover and the tray 212 near each other. Thus, after the cover and the tray 212 are connected together, a corresponding installation cavity can also be obtained. Moreover, when the first groove 101 is provided on both the cover and the tray 212, the first grooves 101 on the two are arranged opposite each other, and the volume of the obtained installation cavity is larger, which can accommodate more fluid. During operation of the liquid supply component gap, the fluid contained in the mounting cavity can continue to wet the flexible cleaning component 22, preventing the flexible cleaning component 22 from temporarily drying out and improving the cleaning ability of the flexible cleaning component 22.

[0082] like Figure 8As shown, the flow guide cavity is arranged around the circumference of the shaft body 321 (that is, the first groove 101 is arranged around the circumference of the shaft body 321), thereby further increasing the capacity of the flow guide cavity, relieving the fluid jetting from the second through hole 102 to the flexible cleaning component 22, and enabling temporary storage of the fluid.

[0083] The second through hole 102 includes multiple (such as one of two, three, four, or other numbers not less than two). The multiple second through holes 102 are arranged circumferentially along the shaft body 321 and are respectively connected to the guide cavity so as to simultaneously provide fluid to the flexible cleaning component 22 through the multiple second through holes 102, thereby improving the wetting efficiency of the flexible cleaning component 22.

[0084] In this implementation, such as Figure 4 and Figure 8 As shown, the flow guiding structure 210 also includes a connecting channel located between the tray 212 and the cover. Along the radial direction of the shaft body 321, the connecting channel is located on the side of the flow guiding cavity away from the shaft body 321 and extends in a direction away from the shaft body 321. Along the radial direction of the shaft body 321, a second through hole 102 is disposed through the bottom of the connecting channel away from the flow guiding cavity. Thus, in this embodiment, the second through hole 102 is connected to the flow guiding cavity via the connecting channel, and the second through hole 102 is located at the bottom of the connecting channel. This not only eliminates the need for a connecting pipe between the flow guiding cavity and the second through hole 102, but also makes the fluid transmission more secure and closed.

[0085] like Figure 8 As shown, in this embodiment, a third groove communicating with the first groove 101 can be provided on the side of the tray 212 near the cover. A second through hole 102 is provided at the bottom of the third groove near the flexible cleaning component 22, and the third groove and the cover form a connecting channel. Alternatively, the third groove can be provided on the side of the cover near the tray 212, or corresponding third grooves can be provided on both the sides of the tray 212 and the cover near each other. After the tray 212 and the cover are connected together, a corresponding connecting channel is obtained. This embodiment reduces the difficulty of processing and setting the connecting channel by creating a third groove, eliminating the need for additional piping components, resulting in low cost and easy assembly.

[0086] Among them, such as Figure 5 and Figure 6 As shown, a plug-in structure 50 is provided between the shaft body 321 and the cleaning component 20. The plug-in structure 50 includes a plug-in hole 51 and a plug-in protrusion 52. The plug-in hole 51 is located on the side of the shaft body 321 near the cleaning component 20. Along the radial direction of the shaft body 321, at least one outlet 401 is provided through the side wall of the plug-in hole 51, that is, at least one outlet 401 penetrates the shaft body 321 radially, and the outlet 401 communicates with the plug-in hole 51.

[0087] A plug-in protrusion 52 is disposed on the side of the cleaning assembly 20 near the shaft body 321, and the plug-in protrusion 52 is provided with at least one second inlet 110. The plug-in protrusion 52 is adapted to the plug-in hole 51, and the plug-in protrusion 52 is inserted into the plug-in hole 51, thereby communicating at least one second inlet 110 with at least one outlet 401. Multiple second inlets 110 may be included (e.g., one of two, three, four, or five, or other numbers greater than two), and the multiple second inlets 110 are arranged at circumferential intervals along the plug-in protrusion 52. Multiple outlets 401 may also be included (e.g., one of two, three, four, or five, or other numbers greater than two), and the multiple outlets 401 can be connected one-to-one with the multiple second inlets 110, thereby improving the discharge efficiency of fluid to the cleaning assembly 20.

[0088] In this embodiment, by setting the second inlet 110 on the insertion protrusion 52 and inserting the insertion protrusion 52 into the insertion hole 51 of the shaft body 321, the difficulty of connecting the outlet 401 and the second inlet 110 is greatly reduced, and the fluid can flow directly to the cleaning component 20 in a relatively sealed space. This further ensures that the fluid coming out of the outlet 401 will not spill into the external environment while wetting the cleaning component 20. After exiting the outlet, the fluid can flow directly to the flexible cleaning element 22 of the cleaning component 20 through the second inlet 110. When the cleaning component 20 is provided with a flow guiding structure 210 (the specific setting and structure of the flow guiding structure 210 can be found in the content mentioned above in this embodiment), at least one second inlet 110 is connected to the flow guiding structure 210. Thus, the fluid entering the second inlet 110 can be guided along the flow guiding path set by the flow guiding structure 210 to the corresponding position of the flexible cleaning element 22, achieving a better wetting effect.

[0089] In other words, in this embodiment, after the insertion protrusion 52 on the cleaning component 20 is inserted into the insertion hole 51 of the shaft body 321, it can be ensured that at least one second inlet 110 can communicate with at least one outlet 401, making assembly efficient and convenient. The fluid coming out of the outlet 401 enters the flow guiding structure 210 along the second inlet 110, and the flow guiding structure 210 then guides the fluid to the flexible cleaning component 22.

[0090] In some embodiments, when the cleaning component 20 is provided with a flow guiding structure 210, a connecting component is provided between the flow guiding structure 210 and at least one outlet 401, the connecting component connecting the flow guiding structure 210 and at least one outlet 401. Thus, after the cleaning component 20 and the drive shaft component 32 are connected together, the connecting component connects the outlet 401 and the flow guiding structure 210 on the cleaning component 20, ensuring that the fluid exiting the outlet 401 flows along the flow guiding structure 210 to the cleaning component 20 and wets the cleaning component 20, facilitating assembly. In this embodiment, the connecting component may include a connecting pipe and at least two pipe joints. At least one pipe joint is located on the cleaning component 20 and connects to the flow guiding structure 210, and at least another pipe joint is located on the drive shaft component 32 and correspondingly connects to at least one outlet 410. The connecting pipe is inserted between the pipe joints, thereby connecting at least one outlet 410 and the flow guiding structure 210.

[0091] When the cleaning assembly 20 includes a support 21 and a flexible cleaning component 22, the flow guiding structure 210 is disposed on the support 21. The flow guiding structure 210 may include a second through hole 102. There are multiple second through holes 102, which are arranged circumferentially along the support 21. The second through holes 102 are connected to the outlet 401 through a connecting component, so that the fluid can flow through the second through holes 102 to the flexible cleaning component 22 to achieve the wetting of the flexible cleaning component 22.

[0092] In some embodiments, the flow guiding structure 210 may include a second through hole 102 and a first groove 101. The first groove 101 is disposed on the bracket 21 and communicates with at least one outlet 401 through a conductive component. Alternatively, a conductive component may not be required between the first groove 101 and the outlet 401. The outlet 401 and the first groove 101 can be arranged opposite each other along the axial direction of the shaft body 321, with the projected outer contour of the outlet 401 positioned within the first groove 101, thus ensuring that the fluid flowing out of the outlet 401 can enter the first groove 101. In this case, the second through hole 102 may penetrate through the bottom of the first groove 101. The second through hole 102 can also be disposed through the bracket 21 at a position offset from the first groove 101, so that the second through hole 102 and the first groove 101 are connected. When connected, a connecting channel can be opened between the second through hole 102 and the first groove 101. The connecting channel can be a groove structure disposed on the surface of the bracket 21, or a channel structure disposed in the bracket 21 and connecting the second through hole 102 and the first groove 101. This embodiment does not limit this to a single one.

[0093] In the case where the bracket 21 of the cleaning component 20 includes a cover and a tray 212, the insertion protrusion 52 can be specifically disposed on the side of the cover near the shaft body 321 and coaxially disposed with the shaft body 321. The insertion protrusion 52 can be connected (e.g., welded, snap-fitted, riveted, etc.) to the cover, or it can be integrally formed with the cover. When integrally formed, the assembly steps of the bracket 21 can be reduced, thereby improving the assembly effect and cost of the cleaning component 20.

[0094] like Figure 4 and Figure 8 As shown, the cleaning device also includes a third seal, which is disposed around the insertion protrusion 52 and located between the cleaning assembly 20 and the shaft body 321 along the circumference of the insertion hole 51. The third seal is used to seal the gap between the insertion protrusion 52 and the end of the shaft body 321 near the cleaning assembly 20. Thus, while at least one second inlet 110 provided on the insertion protrusion 52 corresponds to and communicates with at least one outlet 401, fluid, especially liquid, will not leak from the gap between the insertion protrusion 52 and the end of the shaft body 321, further improving the safety of the fluid transfer process.

[0095] The device body 10 includes a top shell 11 and a bottom shell 12, with the bottom shell 12 located at the bottom of the top shell 11. A drive component 31 is mounted on the bottom shell 12 near the top shell 11, and a first clearance hole 120 is provided through the bottom shell 12. 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, and the length of the first clearance hole 120 is not less than the first distance, so that the cleaning component 20 can accurately switch between the inward-facing state and the outward-facing state.

[0096] like Figure 6 and Figure 7 As shown, a stop structure 325 is provided between the device body 10 and the connecting member 322. The stop structure 325 is used to stop the connecting member 322 in the second state. This ensures the stability and reliability of the connecting member 322 when it is in the second state.

[0097] The device body 10 also includes a sealing plate 13, which is disposed between the cleaning component 20 and the drive component 31. During the movement of the cleaning component 20 from one of the retracted state and the outward expansion state to the other, the sealing plate 13 moves relative to the device body 10 with the cleaning component 20 and covers the first clearance hole 120. The sealing plate 13 protects the drive component 31 and other devices installed between the top shell 11 and the bottom shell 12. The end of the shaft body 321 away from the drive component 31 passes through the first clearance hole 120 and the sealing plate 13 and connects to the cleaning component 20. A stop structure 325 is disposed between the sealing plate 13 and the connecting member 322. Thus, when the sealing plate 13 moves with the cleaning component 20 to one of the retracted state and the outward expansion state, the sealing plate 13 causes the stop structure 325 to remain stationary relative to the device body 10. At this time, the stop structure 325 stops the connecting member 322 in the second state.

[0098] Therefore, in this embodiment, by means of the connection between the sealing plate 13 and the device body 10, the stop structure 325 is set between the sealing plate 13 and the connecting member 322. While the sealing plate 13 achieves the covering and sealing of the first clearance hole 120, the stop structure 325 can limit the connecting member 322 without the need to add a more complex connection system between the connecting member 322 and the device body 10. The overall structure is compact and reliable.

[0099] The process of the cleaning component 20 moving from an inward-retracting state to an outward-expanding state can be a linear motion. In some embodiments, the cleaning component 20 can perform a second rotational motion in a second clockwise direction to move from one of the inward-retracting and outward-expanding states to the other. The sealing plate 13 can also perform a second rotational motion around an axis with the cleaning component 20. The second clockwise direction is opposite to or the same as the first clockwise direction. The cleaning component 20 can perform this second rotational motion under the drive of the outward-expanding drive mechanism 90. In other embodiments, when the cleaning component 20 rotates in the first clockwise direction and is subjected to a frictional torque in the second clockwise direction, the cleaning component 20 can cause the sealing plate 13 and the drive component 30 to swing in the second clockwise direction to the outward-expanding state. When swinging to the outward-expanding state, the cleaning component 20 continues to rotate in the first clockwise direction for edge cleaning. At this time, the second clockwise direction is opposite to the first clockwise direction; for example, if the first clockwise direction is counterclockwise, then the second clockwise direction is clockwise. When the cleaning equipment cleans the ground, the cleaning component 20 is in contact with the ground. During the rotation of the cleaning component 20 by the drive assembly 30 in the first clockwise direction, the ground applies a frictional force to the cleaning component 20 in the second clockwise direction, causing the cleaning component 20 to swing outward relative to the device body 10. This causes the outlet 401 on the drive shaft component 32 to also rotate in the second clockwise direction relative to the device body 10. When the cleaning component 20 rotates in the second clockwise direction and is subjected to a frictional torque in the first clockwise direction, the cleaning component 20 causes the drive shaft component 32 and the sealing plate 13 to rotate in the first clockwise direction to a retracted state. Upon returning to the retracted state, the cleaning component 20 continues to rotate in the second clockwise direction to perform the cleaning work. Regardless of the outward expansion method of the cleaning component 20 described above, during this process, the sealing plate 13 and the drive shaft component 32 swing with the swing of the cleaning component 20. The position of the outlet 401 on the drive shaft component 32 relative to the cleaning component 20 remains unchanged. The fluid exiting the outlet 401 flows directly to the cleaning component 20, preventing splashing onto the ground, walls, furniture, or other objects.

[0100] The stop structure 325 provided in this embodiment includes a second clearance hole 251 and a protrusion 252. The second clearance hole 251 is disposed through the sealing plate 13 of the device body 10. The shaft body 321 passes through the first clearance hole 120 and the second clearance hole 251 and is connected to the cleaning assembly 20. The connecting member 322 is at least partially located in the second clearance hole 251. Along the radial direction of the shaft body 321, the inner wall surface of the second clearance hole 251 is provided with a second groove 511. Along the radial direction of the shaft body 321, the protrusion 252 is disposed on the side of the connecting member 322 near the second groove 511, and the protrusion 252 is at least partially disposed in the second groove 511.

[0101] Therefore, when the connecting member 322 and the shaft body 321 move with the cleaning assembly 20 (such as performing a second rotational movement) to an inward or outward state, the sealing plate 13 remains stationary relative to the device body 10, and the protrusion 252 is blocked by the inner wall of the second groove 511. The connecting member 322, driven by the protrusion 252, also remains stationary relative to the device body 10, while the shaft body 321, driven by the driving component 31, drives the cleaning assembly 20 to perform a first rotational movement relative to the connecting member 322 and the device body 10, thus achieving the cleaning of the surface to be cleaned. This stop structure 325 moves with the sealing plate 13, ensuring that the protrusion 252 on the connecting member 322 is always inserted into the second groove 511. This improves the accuracy and timeliness of stopping the connecting member 322 in the second state, and makes switching the connecting member 322 from the second state to the first state more convenient. The stop structure 325 is also easy to manufacture and assemble, improving the structural compactness and high integration of the cleaning equipment.

[0102] In some embodiments, the device body 10 includes a top shell 11 and a bottom shell 12, with the bottom shell 12 disposed at the bottom of the top shell 11. The stop structure 325 includes a second groove 511 and a protrusion 252. The second groove 511 is disposed on at least one of the bottom shell 12 and the connecting member 322, that is, the second groove 511 may be disposed on only the bottom shell 12 or the connecting member 322, or the second groove 511 may be disposed on both the bottom shell 12 and the connecting member 322. The protrusion 252 is adapted to the second groove 511. The protrusion 252 is provided on at least one of the bottom shell 12 and the connecting member 322. If the second groove 511 is provided on the bottom shell 12, then the protrusion 252 is provided on the connecting member 322. If the second groove 511 is provided on the connecting member 322, then the protrusion 252 is provided on the bottom shell 12. If the second groove 511 is provided on both the connecting member 322 and the bottom shell 12, then the protrusion 252 corresponding to the second groove 511 on the bottom shell 12 is provided on the connecting member 322, and the protrusion 252 corresponding to the second groove 511 on the connecting member 322 is provided on the bottom shell 12. When the cleaning component 20 is in the retracted state and the expanded state, the protrusion 252 is at least partially inserted into the second groove 511. In other words, when the cleaning component 20 moves to the retracted state or the outward expansion state, the connecting member 322 can switch from the first state to the second state by at least partially inserting the protrusion 252 into the second groove 511. The second groove 511 and the protrusion 252 are convenient to set and the assembly is efficient.

[0103] For example, the second groove 511 is provided on the bottom shell 12 of the device body 10, and the protrusion 252 is provided on the outer peripheral wall of the connecting member 322. When the cleaning component 20 drives the shaft body 321 and the connecting member 322 to the retracted state or the expanded state, the protrusion 252 on the connecting member 322 can be at least partially inserted into the second groove 511 to stop the connecting member 322 in the second state. When the cleaning component 20 needs to drive the shaft body 321 from one of the retracted state and the expanded state to the other, the protrusion 252 can be separated from the second groove 511 to switch the connecting member 322 from the second state to the first state.

[0104] Along the height direction of the equipment body 10 (e.g.) Figure 1 (In the direction indicated by the middle arrow Y), the drive component 31 can also drive the transmission shaft component 32 to move the cleaning component 20 up and down between the first position and the second position. The first position is the position where the cleaning component 20 is close to the device body 10. When the cleaning component 20 is not working, it can be driven to the first position to protect or avoid obstacles. The second position is the position where the cleaning component 20 is away from the device body 10, that is, the position where the cleaning component 20 can normally clean the surface to be cleaned. Along the height direction of the device body 10 (this direction can be parallel to the axial direction of the shaft body 321, or it can have a certain angle with the axial direction of the shaft body 321; this embodiment does not impose a unique limitation on this), the second groove 511 extends from the side of the second clearance hole 251 near the drive component 31 to the side of the second clearance hole 251 near the cleaning component 20. When the cleaning component 20 is in the first position and the second position, at least a portion of the protrusion 252 along the axial direction of the shaft body 321 is located in the second groove 511. Therefore, in this embodiment, the second groove 511 is provided through the height direction of the device body 10, and the protrusion 252 is at least partially located in the second groove 511 at both the extreme positions of rising and falling, so that the cooperation between the protrusion 252 and the second groove 511 can limit the connecting member 322 while ensuring that the cleaning component 20 can smoothly switch between the first position and the second position.

[0105] Along the height direction of the device body 10, the first inlet 220 is located on the side of the protrusion 252 away from the cleaning component 20, or closer to the top shell 11, thereby further reducing the processing difficulty of the first inlet 220. Figure 6As shown, a connector 223 can be protruded from the side of the protrusion 252 near the top shell 11. The connector 223 can also be directly disposed on the outer peripheral wall of the connecting member 322. The first inlet 220 is disposed inside the connector 223. When the water tank 411 of the fluid supply component 40 is connected to the first inlet 220 through the second connecting pipe 44, the second connecting pipe 44 can be directly sleeved on the outer periphery of the connector 223, making the connection simple and convenient. At the same time, in order to ensure that the first inlet 220 can be connected to the outlet 401 on the shaft body 321, this embodiment can also provide a first flow channel 520 inside the protrusion 252. One end of the first flow channel 520 is connected to the first inlet 220, and the other end passes through the connecting member 322 and is connected to the first through hole 221 of the connecting member 322. The protrusion 252 can be connected to the connecting member 322, or it can be integrally formed with the connecting member 322. When integrally formed, the assembly steps of the transmission shaft component 32 can be reduced.

[0106] like Figure 7 As shown, the shaft body 321 includes a first shaft segment 201 and a second shaft segment 202. The first shaft segment 201 is connected to the drive component 31. Along the axial direction of the first shaft segment 201, the second shaft segment 202 is detachably connected between the first shaft segment 201 and the cleaning component 20. At least one outlet 401 is provided in the second shaft segment 202, and a connecting member 322 is connected to the second shaft segment 202. The first through hole 221 of the connecting member 322 is sleeved on the second shaft segment 202. Since the second shaft segment 202 and the first shaft segment 201 are detachably connected, the insertion hole 51 is also provided in the second shaft segment 202, which facilitates the processing of the outlet 401 and the insertion hole 51. For example, after the insertion hole 51 is provided through the second shaft segment 202, at least one through hole structure communicating with the insertion hole 51 can be provided through the radial direction of the second shaft segment 202 to obtain the corresponding outlet 401. The processing is convenient and can greatly reduce the assembly difficulty between the second shaft segment 202, the connecting member 322, and the first shaft segment 201.

[0107] A snap-fit ​​structure is provided between the second shaft segment 202 and the first shaft segment 201, which detachably snaps the second shaft segment 202 and the first shaft segment 201 together. For example... Figure 7As shown, the snap-fit ​​structure may include a snap-fit ​​groove and a snap-fit ​​protrusion. When the second shaft segment 202 is provided with a insertion hole 51, the inner wall surface of the insertion hole 51 is provided with at least one of the snap-fit ​​groove and the snap-fit ​​protrusion. At least a portion of the first shaft segment 201 near the second shaft segment 202 is adapted to the insertion hole 51, and the outer wall surface of the portion of the first shaft segment 201 adapted to the insertion hole 51 may also be provided with at least one of the snap-fit ​​groove and the snap-fit ​​protrusion. When at least a portion of the first shaft segment 201 near the second shaft segment 202 is inserted into the insertion hole 51, the snap-fit ​​protrusion and the snap-fit ​​groove snap together, thereby stably and reliably connecting the second shaft segment 202 to the first shaft segment 201. When at least a portion of the first shaft segment 201 passes through the insertion hole 51 and extends to the outlet 401, the first shaft segment 201 is also provided with an outlet 401, and the outlet 401 on the first shaft segment 201 corresponds to and communicates with the outlet 401 on the second shaft segment 202.

[0108] When the connecting member 322 is sleeved onto the second shaft segment 202 through the first through hole 221, an outer flange 2021 is provided on the outer periphery of the end of the second shaft segment 202 away from the first shaft segment 201 along the axial direction of the second shaft segment 202 (e.g., ...). Figure 7 As shown, the connecting piece 322 is sleeved on the second shaft section 202 along with the first through hole 221 and is located on the side of the outer flange 2021 close to the first shaft section 201. The outer flange 2021 close to the surface of the first shaft section 201, the outer peripheral surface of the second shaft section 202, and the inner wall surface of the first through hole 221 can form an installation groove 222, which is efficient and convenient for assembly.

[0109] like Figure 7 As shown, in this embodiment, the first shaft segment 201 may specifically include a shaft 011, a first abutment 012, and a second abutment 013. The shaft 011 is connected to the drive component 31. The first abutment 012 is connected to the shaft 011. Along the axial direction of the shaft 011, the second abutment 013 is connected to the shaft 011 and located on the side of the first abutment 012 away from the drive component 31. The side of the second abutment 013 closest to the first abutment 012 is provided with a track surface 014, and the first abutment 012 is movably abutted against the track surface 014. Along the axial direction of the shaft 011, the track surface 014 has a region closer to the first abutment 012 and a region farther away. Thus, the drive component 31 can be configured to drive the first abutment 012 to move on the track surface 014 to drive the cleaning assembly 20 to move up and down relative to the device body 10.

[0110] In some embodiments, the drive component 31 includes a housing 311, a gear transmission system, and a motor 312. The housing 311 is provided with a mounting cavity and a fixing groove. The gear transmission system is installed in the mounting cavity, and the motor 312 is installed in the fixing groove. The output shaft of the motor 312 is located on the side of the motor 312 closest to the mounting cavity and extends at least partially into the mounting cavity. The gear transmission system is drively connected between the output shaft and the shaft 011.

[0111] In some embodiments, to facilitate the removal of the cleaning component 20, the cleaning component 20 and the shaft body 321 can be detachably connected, including a magnetic connection. For this purpose, a magnetic connection component 80 can be provided between the cleaning component 20 and the shaft body 321, such as... Figure 4 As shown, the magnetic connection assembly 80 includes a magnet 81 and a ferromagnetic component 82. The magnet 81 is disposed on the cleaning assembly 20, and the ferromagnetic component 82 is disposed on the shaft body 321, so that the cleaning assembly 20 and the shaft body 321 are stably connected together by the magnetic attraction between the magnet 81 and the ferromagnetic component 82.

[0112] Meanwhile, when the insertion protrusion 52 on the cleaning component 20 is inserted into the insertion hole 51 of the shaft body 321, in order to ensure that the cleaning component 20 can make a first rotational movement under the drive of the shaft body 321, the projected outer contour of the insertion protrusion 52 along the axial direction of the shaft body 321 can be a polygonal structure (such as one of a pentagon or a hexagon), and the projected outer contour of the inner wall of the insertion hole 51 is a polygonal structure that matches the projected outer contour of the insertion protrusion 52. Thus, the torque for making the first rotational movement is transmitted through the polygonal contours of the insertion protrusion 52 and the insertion hole 51.

[0113] The ferromagnetic component 82 may include at least one of the following: iron-chromium-cobalt component, aluminum-nickel-cobalt component, neodymium-iron-boron component, ferrite component, etc.

[0114] Specifically, when the support 21 of the cleaning component 20 includes a tray 212 and a cover, the insertion protrusion 52 is provided on the side of the cover near the shaft body 321, such as... Figure 9As shown, the insertion protrusion 52 has a clearance groove on the side near the tray 212 that communicates with the first groove 101 on the tray 212. At least one second inlet 110 can be disposed through the side wall of the clearance groove, allowing the second inlet 110 to communicate with the first groove 101 of the guide structure 210. The clearance groove has a cross-section radially along the shaft body 321. Along the axial direction of the shaft body 321, the cross-section on the side of the clearance groove away from the shaft body 321 is larger than the cross-section on the side near the shaft body 321. A magnet 81 can be fixed to the side of the tray 212 near the cover and embedded in the clearance groove on the side near the shaft body 321. At least one second inlet 110 communicates with the side of the clearance groove away from the shaft body 321. The overall structure is compact, reliable, and easy to assemble. The ferromagnetic component 82 can be set on the side of the first shaft section 201 of the shaft body 321 near the second shaft section 202. When the insertion protrusion 52 on the cover is inserted into the insertion hole 51, it can ensure that the magnet 81 and the ferromagnetic component 82 are attracted together.

[0115] like Figure 1 as well as Figures 9 to 11 As shown, the fluid supply assembly 40 provided in this embodiment includes a fluid supply component 41, a diverter 42, a first connecting pipe 43, and a second connecting pipe 44.

[0116] In some embodiments, the fluid supply component 41 may include a water tank 411, a pump 412, and a heating device 413. The water tank 411 is located on the device body 10, specifically between the top shell 11 and the bottom shell 12 of the device body 10. The pump 412 is located on the device body 10 and includes a first interface and a second interface, the first interface communicating with the water tank 411. The heating device 413 is located on the device body 10 and includes a third interface and a fourth interface, the third interface communicating with the second interface and the fourth interface communicating with at least one outlet 401. In other embodiments, when it is not necessary to provide warm or hot water to the cleaning component 20, the fluid supply component 41 may not require a heating device 413; the pump 412 (e.g., a water pump) can directly draw liquid from the water tank 411 to the outlet 401. When a heating device 413 is provided, the pumping component 412 can draw liquid, or water, from the water tank 411 to the heating device 413. The heating device 413 can heat the water into hot or warm water, and then directly transmit the hot or warm water to at least one outlet 401. When the drive shaft component 32 includes a connecting component 322, after the fluid exits from the heating device 413, the specific flow path of the fluid includes: first inlet 220 → first flow channel 520 → mounting groove 222 → outlet 401 → guide structure 210, and finally arrives at the flexible cleaning component 22 of the cleaning assembly 20.

[0117] like Figure 12The fluid supply component 40 also includes at least one inlet 402. In this embodiment, the cleaning component 20 includes an external cleaning component and a static cleaning component (such as...). Figure 9 (The left side of the image shows a static cleaning component, and the right side shows an expanding cleaning component). The expanding and static cleaning components are arranged at the bottom of the device body 10. The expanding cleaning components have an inward-facing state and an outward-facing state, and the drive shaft component 32 connected to at least one set of expanding cleaning components is provided with at least one outlet 401. Thus, during the movement of at least one set of expanding cleaning components from one of the inward-facing and outward-facing states to the other, since the drive shaft component 32 can move with the expanding cleaning components between the inward-facing and outward-facing states, the outlet 401 will also move with the movement of the drive shaft component 32 and the expanding cleaning components. Therefore, the position of the outlet 401, which supplies fluid to the expanding cleaning components, relative to the expanding cleaning components always remains unchanged, and the fluid flowing out of the outlet 401 can flow directly onto the expanding cleaning components without flowing to places other than the expanding cleaning components. In particular, when the fluid includes liquid, it can prevent liquid from splashing onto the ground, walls, furniture, etc.

[0118] The static cleaning component remains in the retracted state. At least one inlet 402 is located at the bottom of the device body 10, and at least a portion of the inlet 402 is positioned opposite the static cleaning component. For example, along the height direction of the device body 10, the projection of the at least one inlet 402 onto the static cleaning component is at least partially located within the flow guide structure 210 on the static cleaning component, so that the liquid exiting the inlet 402 can flow into the flow guide structure 210 and wet the static cleaning component. If the device body 10 includes a top shell 11 and a bottom shell 12, the at least one inlet 402 can be located on the bottom shell 12, which is simple and convenient. In other words, when the cleaning component includes at least one set of static cleaning components, it is not necessary to provide an outlet 401 on the drive shaft component 32 connected to the static cleaning component. Instead, an inlet 402 corresponding to the static cleaning component can be provided at the bottom of the device body 10, which improves assembly efficiency and can further save costs.

[0119] In this embodiment, the cleaning component 20 includes at least two sets, and the at least two sets of cleaning components 20 are aligned along a first direction (e.g., Figure 1 Arranged in the direction indicated by the middle arrow X, the drive shaft components 32 include at least two sets, and each of the at least two sets of drive shaft components 32 is connected to at least two sets of cleaning components 20 in a one-to-one correspondence. The diverter 42 includes a first connector 421 and at least two second connectors 422, and each of the at least two second connectors 422 is connected to the first connector 421. The first connecting pipe 43 connects the fluid supply component 41 and the first connector 421, and the first connecting pipe 43 specifically connects the fourth interface of the heating device 413 and the first connector 421. When the cleaning components 20 include two sets, the diverter 42 may specifically be a tee connector.

[0120] The second connecting pipe 44 includes at least two pipes. At least one second connecting pipe 44 connects to at least one second connector 422 and at least one outlet 401 of at least one set of drive shaft components 32. At least another second connecting pipe 44 connects to at least another second connector 422 and at least one outlet 401 of at least another set of drive shaft components 32. The length of the second connecting pipe 44 is greater than the distance between the second connector 422 and the outlet 401. Thus, the first connecting pipe 43 transmits the flow from the heating device 413 to the diverter 42. The diverter 42 transmits the fluid through the at least two second connecting pipes 44 to the outlet 401 of the drive shaft component 32 corresponding to different cleaning components 20, so as to achieve simultaneous immersion of at least two sets of cleaning components 20. The fluid flowing to at least two sets of cleaning components 20 is not easily leaked into the external environment, resulting in a better user experience. Meanwhile, since the length of the second connecting pipe 44 is greater than the distance between the second connector 422 and the outlet 401, the length of the second connecting pipe 44 is also greater than the distance between the second connector 422 and the first inlet 220. During the process of the cleaning component 20 driving the connecting member 322, which is provided with the first inlet 220, to switch between the inward state and the outward state, the end of the second connecting pipe 44 near the first inlet 220 can also move with the movement of the connecting member 322, thereby avoiding the second connecting pipe 44 from detaching or even breaking.

[0121] Since the second connecting pipe 44 moves with the connecting member 322, in order to improve the stability of the diversion joint 42 and prevent the diversion joint 42 from shaking due to the pulling of the second connecting pipe 44, this embodiment can position the water tank 411 between two adjacent sets of cleaning components 20. Figure 9 As shown, a limiting groove 4111 is provided on the water tank 411, which can fix the diversion connector 42 in the limiting groove 4111 by fasteners (such as screws, bolts, rivets, etc.). The portion of the limiting groove 4111 corresponding to the first connector 421 and at least two second connectors 422 extends to the outer edge of the water tank 411, so that the portions of the first connecting pipe 43 and the second connecting pipe 44 near the diversion connector 42 can be laid in the limiting groove 4111, improving the structural stability between the diversion connector 42, the first connecting pipe 43, and the second connecting pipe 44. A limiting groove 4111 adapted to the first connecting pipe 43 can also be provided in the area of ​​the equipment body 10 between the heating device 413 and the water tank 411. For example, a limiting groove 4111 can be provided on the outer shell of the expansion drive mechanism 90 to lay the portion of the first connecting pipe 43 between the water tank 411 and the heating device 413 in the limiting groove 4111.

[0122] Furthermore, in this embodiment, a limiting hole 4112 is provided on the side of the water tank 411 near the connecting member 322. After the second connecting pipe 44 is laid along the limiting groove 4111, it passes through the limiting hole 4112 and connects with the first inlet 220 on the connecting member 322. The limiting hole 4112 can further improve the stability of the second connecting pipe 44, ensuring that the second connecting pipe 44 will not get tangled or partially move to some corner areas of the device body 10 and get stuck during the movement of the connecting member 322.

[0123] When the cleaning equipment includes at least one set of static cleaning components, since the static cleaning components do not need to move between an inward and outward state, at least one inlet 402 can be provided on the bottom shell 12 of the equipment body 10, and the outer contour of the projection of at least one inlet 402 along the height direction of the equipment body 10 can be at least partially located on the flow guiding structure 210 of the cleaning component 20 to achieve wetting of the static cleaning component 20. Of course, the static cleaning component 20 can also be supplied with fluid through the outlet 401 provided on the drive shaft component 32, and the second connecting pipe 44 can be connected to the outlet 401 to achieve fluid replenishment operation of the static cleaning component.

[0124] In some embodiments, the fluid supply assembly 40 includes a water injection component and a fluid supply component 41, with the water injection component located on the device body 10. The fluid supply component 41, located on the device body 10, includes a water tank 411, a water pumping component 412, and a heating device 413. The water tank 411 is connected to the water injection component, the water pumping component 412 is connected between the water tank 411 and the heating device 413, and the heating device 413 is connected to at least one outlet 401. After the cleaning equipment returns to the base station, the base station can inject water into the water tank 411 through the water injection component. The water pumping component 412 can pump the water from the water tank 411 to the heating device 413. The heating device 413 heats the water into hot water and guides it to the cleaning assembly 20 through at least one outlet 401. The hot water wets the cleaning assembly 20 and enhances its ability to dissolve stubborn stains (such as grease), thereby better cleaning the stubborn stains on the surface to be cleaned. Secondly, due to the high temperature of the hot water, it can effectively kill bacteria and mites on the cleaning component 20, achieving the purpose of disinfection and sterilization. The water injection component may include a water inlet and a water injection pipe. The water inlet is located on the device body 10 and is connected to the clean water tank of the base station when the cleaning device returns to the base station. One end of the water injection pipe is connected to the water inlet, and the other end is connected to the water tank 411, making assembly convenient.

[0125] 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. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0126] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0127] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
