Description

Technical Field

[0001] This application relates to the field of clean technology, and more specifically, to a cleaning device, a base station, and a cleaning system. 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, allowing them to perform wet cleaning by contacting the mop with the surface to be cleaned (such as the floor or tabletop). To provide water to the mop for wetting, a water tank is installed inside the cleaning robot. After returning to the base station, the cleaning robot needs to have the water tank refilled by the base station. The water tank is equipped with a full-fill detection device to check if it is full. When the tank is full, the base station can stop refilling to prevent water from overflowing and causing short circuits or damage to the robot's internal electronic components. However, the full-fill detection device increases the cost of the cleaning robot. Utility Model Content

[0036] On the other hand, this application also provides a base station for docking the cleaning equipment. Along the height direction of the base station, a cleaning tank is provided at the bottom of the base station. When the cleaning components of the cleaning equipment are located in the cleaning tank, the overflow port of the cleaning equipment is connected to the cleaning tank.

[0037] On the other hand, this application also provides a cleaning system, the cleaning system comprising:

[0038] A cleaning device includes a main body and a water tank. The water tank is located in the main body and has a liquid storage chamber, a first water inlet, and a tank overflow outlet. The first water inlet and the tank overflow outlet are respectively connected to the liquid storage chamber. Along the height direction of the main body, there is a first height between the tank overflow outlet and the bottom of the liquid storage chamber.

[0039] The cleaning equipment can be selectively docked at the base station. A cleaning tank is provided at the bottom of the base station along the height direction of the base station. The base station is also equipped with a water injection component. The water injection component is connected to the first water inlet to inject water into the liquid storage chamber. The overflow port of the tank is configured to discharge excess water into the cleaning tank when the water level in the liquid storage chamber is higher than the first height.

[0040] The cleaning equipment provided in this application includes a main body and a water tank, with the water tank located within the main body, specifically within the installation space of the main body. The water tank has a storage chamber, a first inlet, and an overflow outlet. The first inlet and the overflow outlet are respectively connected to the storage chamber. Along the height direction of the main body, there is a first height between the overflow outlet and the bottom of the storage chamber. The overflow outlet is configured to discharge excess water into the cleaning tank of the base station when the water level in the storage chamber exceeds the first height. In other words, after the cleaning equipment returns to the base station, during the process of the base station filling the storage chamber with water, if the water level in the storage chamber exceeds the first height, excess water can overflow from the storage chamber through the overflow outlet and be discharged into the cleaning tank of the base station. At this time, connecting the overflow outlet to a corresponding transmission pipe, and connecting the transmission pipe to the cleaning tank, allows the excess water to be discharged into the cleaning tank. This water tank eliminates the need for a full-water detection device, reducing the cost of the water tank. Meanwhile, when the base station performs corresponding maintenance on the cleaning equipment, it can perform maintenance in the following order: dust collection, water injection, cleaning (mop) and drying and charging. Since water injection is performed before cleaning the mop, the excess water discharged from the water tank through the overflow port after water injection will not have an adverse effect on the subsequent cleaning of the mop, thus avoiding watermarks on the surface to be cleaned when the mop leaves the station due to excessive water content.

[0058] 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.

[0059] 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. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0060] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. 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.

[0061] Existing cleaning robots, due to the inclusion of liquid level detection devices, increase both manufacturing and operating costs. These devices typically employ magnetic buoys and Hall effect sensors. The magnetic buoy is positioned inside the water tank 20, while the Hall effect sensor is located nearby. The Hall effect sensor determines whether the tank is full by detecting the height of the buoy as it floats within the tank. When full, it sends a signal to the cleaning equipment, which then informs the base station to stop filling. However, the buoy's magnetism may weaken over time, and the Hall effect sensor itself may be damaged. This affects the effectiveness of the liquid level detection device, ultimately reducing its reliability. To prevent malfunctions or failures, the liquid level detection device requires regular maintenance or even replacement, causing considerable inconvenience to users.

[0062] To address the aforementioned problems, the first embodiment of this utility model provides a cleaning device, please refer to [link / reference]. Figures 1 to 10 The cleaning device includes a main body 10 and a water tank 20, with the water tank 20 located within the main body 10. Specifically, the water tank 20 may be located within an installation space inside the main body 10, or it may be at least partially located within and at least partially located outside the installation space; this embodiment does not impose a single limitation on this. The water tank 20 is provided with a liquid storage chamber 01, a first water inlet 02, and a tank overflow outlet 03. The first water inlet 02 and the tank overflow outlet 03 are respectively connected to the liquid storage chamber 01. Along the height direction of the main body 10 (e.g., ... Figure 1 (in the direction indicated by the middle arrow X), there is a first height (e.g., the overflow port 03 of the tank and the bottom of the storage chamber 01) between them. Figure 5 As indicated by H), the overflow port 03 of the box is configured to discharge excess water into the cleaning tank 92 of the base station 90 when the water level in the liquid storage chamber 01 is higher than the first height.

[0063] During the process of the cleaning equipment returning to the base station 90 to allow the base station 90 to fill its water tank 20, if the water level in the liquid storage chamber 01 exceeds the first height, the excess water can be discharged through the overflow port 03 of the tank. This eliminates the need for a full-fill detection device, preventing damage or leakage to the water tank 20 due to overfilling, thus reducing costs. The water that does not overflow from the water tank 20 can then be supplied to the cleaning component 30 of the cleaning equipment, thereby wetting the cleaning component 30 and improving its cleaning effect on surfaces (such as floors and tabletops).

[0064] As can be seen, the cleaning equipment provided in this embodiment includes a main body 10 and a water tank 20. The water tank 20 is located in the main body 10, specifically within the installation space inside the main body 10. The water tank 20 is provided with a liquid storage chamber 01, a first water inlet 02, and a tank overflow port 03. The first water inlet 02 and the tank overflow port 03 are respectively connected to the liquid storage chamber 01. Along the height direction of the main body 10, there is a first height between the tank overflow port 03 and the bottom of the liquid storage chamber 01. The tank overflow port 03 is configured to discharge excess water into the cleaning tank 92 of the base station 90 when the water level in the liquid storage chamber 01 is higher than the first height. In other words, after the cleaning equipment returns to the base station 90, during the process of the base station 90 filling the liquid storage chamber 01 of the water tank 20 with water, if the water level in the liquid storage chamber 01 is higher than the first height, the excess water can overflow from the liquid storage chamber 01 through the overflow port 03 and be discharged into the cleaning tank 92 of the base station 90. At this time, connecting the overflow port 03 to the corresponding flexible pipe, and connecting the flexible pipe to the cleaning tank 92, will allow the excess water to be discharged into the cleaning tank 92. This eliminates the need for a full-liquidity detection device in the water tank 20, reducing its cost. Meanwhile, when the base station 90 performs corresponding maintenance on the cleaning equipment returning to the station, it can perform maintenance on the cleaning equipment in the following order: dust collection - water injection - cleaning (mop 32) - drying and charging. Since water injection is performed before cleaning mop 32, after water injection, the excess water discharged from the water tank 20 through the overflow port 03 will not have an adverse effect on the subsequent cleaning of mop 32, even if it flows onto the mop 32. This can prevent the mop 32 from leaving the station with watermarks due to its high water content after cleaning.

[0065] In this embodiment, the overflow port 03 of the box can be connected to the connecting pipe. After the cleaning equipment returns to the base station 90, the water overflowing from the overflow port 03 of the box can be transferred and discharged to the cleaning tank 92 of the base station 90 through the connecting pipe, thereby avoiding the overflowing water from causing adverse effects on other components of the cleaning equipment.

[0066] like Figure 3As shown, a main overflow port 11 is provided at the bottom of the main body 10 along its height direction, and the main overflow port 11 is connected to the overflow port 03 of the casing. Therefore, after the cleaning equipment returns to the base station 90, the main overflow port 11 can be positioned directly opposite the cleaning tank 92 of the base station 90, and the overflow port 03 of the casing can discharge excess water from the water tank 20 into the cleaning tank 92 through the main overflow port 11, making the discharge method convenient and quick. No additional connecting pipes are needed between the main body 10 and the cleaning tank 92, further reducing costs and making the assembly process of the cleaning equipment more efficient and convenient. The main overflow port 11 and the overflow port 03 of the casing can be connected via a flexible hose or a rigid pipe, making the connection simple and convenient.

[0067] Please see Figures 4 to 9 The water tank 20 includes a tank body 21 and a flow guiding component 22, with a liquid storage chamber 01 disposed within the tank body 21. The flow guiding component 22 is disposed within the liquid storage chamber 01. Along the height direction of the main body 10, the flow guiding component 22 and the top surface of the liquid storage chamber 01 enclose an overflow chamber 201 (e.g., ...). Figure 6 As shown, the top surface of the storage chamber 01 is the inner wall surface of the storage chamber 01 that is away from its bottom along the height direction of the main body 10. The overflow port 03 of the tank is provided on the side wall of the overflow chamber 201 and connects the overflow chamber 201 and the storage chamber 01. The main overflow port 11 is connected to the overflow chamber 201. Thus, when the water level in the storage chamber 01 reaches the overflow port 03 of the tank, the overflow port 03 of the tank discharges the excess water out of the storage chamber 01 in sequence along the overflow chamber 201, the first channel 2211 and the main overflow port 11. The main overflow port 11 and the first channel 2211 can be directly connected by a hose.

[0068] In this embodiment, an overflow cavity 201 is formed between the guide component 22 and the top surface of the liquid storage cavity 01, allowing the overflow port 03 of the tank and the first channel 2211 to be connected through the overflow cavity 201. Since the overflow cavity 201 can temporarily store a large amount of water, it can alleviate the pressure of the overflow port 03 of the tank on the discharge of excess water, and can also bring greater water pressure to the main overflow port 11, increasing the speed at which water flows out of the main overflow port 11, thereby improving the overflow efficiency of excess water and achieving rapid overflow.

[0069] like Figures 5 to 7As shown, the tank 21 includes a first outer shell 211 and a second outer shell 212. Along the height direction of the main body 10, the second outer shell 212 is located above the first outer shell 211 and forms a liquid storage cavity 01 with the first outer shell 211. The flow guiding component 22 includes a protrusion 221 and a connecting block 222. The protrusion 221 protrudes from the side of the first outer shell 211 near the second outer shell 212. The protrusion 221 can be connected to the first outer shell 211 by a predetermined connection method (such as welding, riveting, plugging, snapping, etc.), or it can be integrally formed with the first outer shell 211. When integrally formed, the assembly process and complexity of the water tank 20 can be reduced. A first channel 2211 is provided inside the protrusion 221, and the first channel 2211 communicates with the main overflow port 11. The first channel 2211 can penetrate and extend to the bottom of the first outer shell 211 away from the second outer shell 212, and then the first channel 2211 and the main overflow port 11 can be connected by a flexible hose or rigid pipe.

[0070] A connecting block 222 is disposed at one end of the protrusion 221 near the second outer shell 212. The connecting block 222 covers the first channel 2211 and forms an overflow cavity 201 with the inner wall of the second outer shell 212. A first connecting hole 2221 is provided in the connecting block 222, which connects the first channel 2211 and the overflow cavity 201. Thus, excess water enters the overflow cavity 201 from the overflow port 03 of the tank, is transferred to the first channel 2211 through the first connecting hole 2221, and then flows to the main overflow port 11 through the first channel 2211 and into the cleaning tank 92 of the base station 90. The guide component 22 composed of the protrusion 221 and the connecting block 222 is easy to assemble, and the first connecting hole 2221 connecting the overflow cavity 201 and the first channel 2211 is easy to process. Secondly, since the overflow chamber 201 can temporarily store a large amount of water, it can bring a large water pressure to the first channel 2211 through the first connection hole 2221, thereby increasing the flow rate of water from the first channel 2211 to the main overflow port 11 and thus improving the overflow efficiency of the main overflow port 11.

[0071] A plug-in structure 70 is provided between the connecting block 222 and the protrusion 221. The plug-in structure 70 allows the connecting block 222 to be quickly plugged into the protrusion 221, making assembly efficient and convenient. Figure 7 and Figure 9It is understood that the insertion structure 70 includes an insertion boss 71 and an insertion groove 72. Along the height direction of the main body 10, the insertion boss 71 is located at the top of the protrusion 221 away from the first outer shell 211 and surrounds the opening of the first channel 2211, thus enclosing the opening of the first channel 2211. The insertion groove 72 is located on the side of the connecting block 222 near the protrusion 221 and surrounds the first connecting hole 2221. The insertion boss 71 is adapted to the insertion groove 72 and is inserted into it. Therefore, after the connecting block 222 is inserted into the protrusion 221 through the insertion structure 70, the first connecting hole 2221 and the first channel 2211 are connected, ensuring efficient and convenient assembly and guaranteeing the sealing of the connection between the first connecting hole 2221 and the first channel 2211. The insertion groove 72 is a groove structure located within an annular protrusion that surrounds the first connecting hole 2221.

[0072] When the protrusion 221 of the flow guide component 22 is provided with a first channel 2211 connecting the overflow chamber 201 and the main overflow port 11, the axis of the first channel 2211 is parallel to the height direction of the main body 10, that is, the first channel 2211 is vertically opened along the direction of gravity of the water. Along the height direction of the main body 10, the horizontal plane of the main overflow port 11 is lower than the horizontal plane of the first channel 2211. As a result, excess water flowing out of the overflow port 03 of the tank can flow quickly to the main overflow port 11 along the first channel 2211 under the action of gravity. There is no need to open an additional power source (such as a water pump) to increase the water power between the main overflow port 11 and the overflow port 03 of the tank, making the cleaning equipment more energy-efficient and lower in cost.

[0073] like Figure 8 As shown, along the height direction of the main body 10, the flow guiding component 22 is provided with a first groove 2222 on the side near the top surface of the liquid storage chamber 01. The outer peripheral wall of the first groove 2222 is provided with a first notch 2223, which connects the first groove 2222 and the liquid storage chamber 01. The first groove 2222 and the top surface of the liquid storage chamber 01 (which is the inner wall surface of the second outer shell 212 near the liquid storage chamber 01) form an overflow chamber 201, and an overflow port 03 is formed at the first notch 2223.

[0074] In other words, this embodiment, by setting a first groove 2222 on the flow guide component 22 and opening a first notch 2223 on the first groove 2222, after placing the flow guide component 22 inside the housing 21 (specifically between the first outer shell 211 and the second outer shell 212 of the housing 21), can obtain the overflow cavity 201 and the overflow port 03 of the tank. Both the first groove 2222 and the first notch 2223 are easy to process, thereby reducing the difficulty of setting the overflow cavity 201 and the overflow port 03 of the water tank 20, and improving the assembly efficiency of the water tank 20. Specifically, the first groove 2222 can be set on the side of the connecting block 222 away from the protrusion 221, and the first connecting hole 2221 is opened at the bottom of the first groove 2222 to connect the first groove 2222 and the first channel 2211.

[0075] The main body 10 is provided with a water inlet 12. The flow guiding component 22 and the top surface of the liquid storage chamber 01 also form a water injection chamber 202, which is connected to the water inlet 12 (the water inlet 12 can be connected to the water injection chamber 202 through a water injection pipe). The first water inlet 02 is provided on the side wall of the water injection chamber 202 and connects the water injection chamber 202 and the liquid storage chamber 01. When the water tank 20 is not provided with a water injection chamber 202, the water inlet 12 can be directly connected to the first water inlet 02.

[0076] like Figure 14 After the cleaning equipment returns to the base station 90, the water inlet 12 connects to the clean water tank 941 of the base station 90, allowing the base station 90 to inject clean water into the water tank 20 of the cleaning equipment through the water inlet 12. At this time, a water inlet 943 is provided in the receiving cavity 91 at the bottom of the base station 90, which can connect with the water inlet 12. The water inlet 943 connects to the clean water tank 941 of the base station 90, and a first water pump 942 is provided between the water inlet 943 and the clean water tank 941. When the cleaning equipment returns to the base station 90 and moves to the position where it connects with the water inlet 943, the base station 90 can then use the first water pump 942 to inject water from the clean water tank 941 into the water tank 20 of the cleaning equipment through the water inlet 943.

[0077] In this embodiment, by setting a water injection chamber 202 between the water injection port 12 and the first water inlet 02 of the water tank 20, when the water flow rate injected by the base station 90 into the water injection port 12 through the water injection interface 943 is large, the water injection pressure of the first water inlet 02 being discharged into the liquid storage chamber 01 can be relieved, thereby improving the safety and reliability of the water injection process.

[0078] Secondly, in this embodiment, the first water inlet 02 and the tank overflow outlet 03 are respectively located on opposite sides of the flow guiding component 22, such as when the flow guiding component 22 is positioned along the direction of travel of the cleaning equipment ( Figure 1The water inlet 02 and the overflow outlet 03 are located on opposite sides of the direction indicated by the middle arrow Y, or on opposite sides of the guide component 22 along the width direction of the main body 10, to ensure that the distance between the first inlet 02 and the overflow outlet 03 is large, preventing water injected into the water tank 20 from the first inlet 02 from flowing to the overflow outlet 03 and being discharged from the overflow outlet 03, thereby avoiding the problem of low water injection efficiency. The width direction of the main body 10 (hereinafter defined as the first direction) is... Figure 1 The direction indicated by the middle arrow z.

[0079] A second groove 2224 is provided on the side of the flow guide component 22 near the top surface of the liquid storage chamber 01. The second groove 2224 is located on one side of the overflow chamber 201 and is spaced apart from the overflow chamber 201. A second notch 2225 is provided on the outer peripheral wall of the second groove 2224, which connects the second groove 2224 and the liquid storage chamber 01. The second groove 2224 and the top surface of the liquid storage chamber 01 form a water injection chamber 202, and a first water inlet 02 is formed at the second notch 2225. In this embodiment, by providing a second groove 2224 on the flow guide component 22 and opening a second notch 2225 on the second groove 2224, the water injection chamber 202 and the first water inlet 02 can be obtained at the same time as assembling the flow guide component 22 and the housing 21, making assembly efficient and convenient. Moreover, both the second groove 2224 and the second notch 2225 are easy to process, which can reduce the difficulty of opening the water injection chamber 202 and the first water inlet 02.

[0080] like Figure 8 As shown, in this embodiment, the second groove 2224 is also specifically disposed on the top of the connecting block 222 away from the protrusion 221. In order to make the distance between the first water inlet 02 and the overflow port 03 of the tank far apart, the first notch 2223 can be located on one side of the connecting block 222 along the width direction of the main body 10, and the second notch 2225 can be located on the other side of the connecting block 222 along the width direction of the main body 10. The first notch 2223 and the second notch 2225 are arranged at intervals along the traveling direction of the cleaning equipment, so that the first water inlet 02 and the overflow port 03 of the tank are located on opposite sides of the width direction of the main body 10 and are also arranged at intervals along the traveling direction of the cleaning equipment.

[0081] In some embodiments, along the height direction of the main body 10, a water outlet 13 is also provided at the bottom of the main body 10. The water outlet 13 is spaced apart from the main overflow outlet 11 and communicates with the water tank 20. The cleaning equipment also includes a cleaning component 30, which is located at the bottom of the main body 10. The cleaning component 30 is at least partially disposed opposite to the water outlet 13 (specifically, the first through hole 3111 provided on the cleaning component 30 is disposed opposite to the water outlet 13), so that the water tank 20 can provide clean water to the cleaning component 30 through the water outlet 13, thereby wetting the cleaning component 30. The width of the main overflow outlet 11 is greater than the width of the water outlet 13, so that excess water can quickly overflow from the main overflow outlet 11 into the cleaning tank 92 of the base station 90. A second water pump 176 is installed between the water outlet 13 and the water tank 20. The second water pump 176 includes a first interface and a second interface, the first interface communicating with the water tank 20 and the second interface communicating with the water outlet 13. During the cleaning process, the second water pump 176 can be started to draw water from the water tank 20 to the outlet 13, and then the water flows to the cleaning component 30 through the outlet 13.

[0082] In this embodiment, the shapes of both the main overflow port 11 and the outlet 13 can include at least one of the following: circular hole, rectangular hole, rhomboid hole, elliptical hole, polygonal hole, etc. When both the main overflow port 11 and the outlet 13 are circular holes, their respective widths are equal to the diameter of the circular hole; when both the main overflow port 11 and the outlet 13 are rectangular holes, their respective widths are equal to the length of the rectangle. Having at least one of the main overflow port 11 and the outlet 13 as a circular hole is convenient for processing and can reduce the flow resistance of the water.

[0083] Combination Figures 1 to 3 as well as Figure 10 As can be seen, the cleaning component 30 in this embodiment may include a bracket 31 and a mop 32, with the mop 32 disposed on the surface of the bracket 31 away from the main body 10. At least one first through hole 3111 may be provided on the bracket 31, with the first through hole 3111 opposite to the water outlet 13. Water dripping from the water outlet 13 into the first through hole 3111 can directly act on the mop 32, achieving the purpose of soaking the mop 32. When the cleaning device also includes a drive mechanism 80 for driving the cleaning component 30 to rotate, the drive mechanism 80 may include a drive member and a transmission shaft. The drive member is disposed within the main body 10, and one end of the transmission shaft is connected to the drive member, while the other end is connected to the bracket 31. The drive member drives the transmission shaft to rotate the bracket 31 around the axis of the transmission shaft. Multiple first through holes 3111 may be provided, spaced apart along the rotation direction of the cleaning component 30, and at least one or more water outlets 13 may correspond to the multiple first through holes 3111.

[0084] In some embodiments, the cleaning equipment also includes a cleaning component 30, which is located at the bottom of the main body 10. Along the height direction of the main body 10, the cleaning component 30 has a first projection area at the bottom of the main body 10, which is offset from the main overflow port 11. That is, the main overflow port 11 is not corresponding to the cleaning component 30, especially the first through hole 3111 on the cleaning component 30, thereby preventing water overflowing from the main overflow port 11 from falling onto the mop 32. Thus, after the cleaning equipment returns to the base station 90, regardless of whether the base station 90 first fills the water tank 20 of the cleaning equipment or first cleans the cleaning component 30, the excess water in the water tank 20 can flow directly into the cleaning tank 92 of the base station 90 through the main overflow port 11. The water coming out of the main overflow port 11 will not drip onto the cleaning component 30, avoiding excessive water content in the cleaning equipment when it leaves the base station. During the cleaning process, the cleaning equipment will not leave obvious watermarks on the surface to be cleaned, resulting in a better user experience.

[0085] like Figure 6 and Figure 7 As shown, the water tank 20 is also provided with a water inlet 04. One end of the water inlet 04 can be connected to the water inlet 12 through a water inlet pipe, and the other end of the water inlet 04 can pass through the protrusion 221 to communicate with the first water inlet 02 or the water inlet cavity 202. To achieve rapid overflow, in this embodiment, the size of the water inlet 04 can be smaller than the size of the main overflow port 11, so that the larger main overflow port 11 can discharge excess water more quickly and prevent the water tank 20 from overflowing and contaminating the internal components of the main body 10. A second connecting hole 2226 is opened at the bottom of the second groove 2224, and the second connecting hole 2226 connects the water inlet 04 and the second groove 2224. This allows the water inlet 04 and the water inlet cavity 202 to communicate, and the second connecting hole 2226 is easy to process.

[0086] The connecting block 222 can include one or more first connecting holes 2221 and second connecting holes 2226. When there are multiple first connecting holes 2221, at least one first connecting hole 2221 is located in the middle of the first groove 2222, and at least two other first connecting holes 2221 are arranged around the middle first connecting hole 2221. When there are multiple second connecting holes 2226, they can be arranged in the same way as the multiple first connecting holes 2221. The multiple first connecting holes 2221 can accelerate the flow of excess water out of the overflow chamber 201, and the arrangement of multiple second connecting holes 2226 can accelerate the entry of water into the water tank 20 from the water inlet 12.

[0087] In this embodiment, the size of the main overflow port 11 can also be made smaller than that of the water inlet hole 04. For example, if the width of the water inlet hole 04 is 3 mm, the width of the main overflow port 11 can be greater than or equal to 2 mm and less than or equal to 3 mm (when the main overflow port 11 is a circular hole, that is, the diameter of the main overflow port 11 is greater than or equal to 2 mm and less than or equal to 3 mm). A smaller main overflow port 11 can more accurately control the water level in the water tank 20, avoiding excessive water level fluctuations due to excessive overflow, which would reduce the actual water storage capacity of the water tank 20. This helps to stabilize the water level in the water tank 20 at a predetermined level (such as at the first height level in this embodiment), so that there is enough water to supply the cleaning component 30 during the cleaning process. Secondly, a smaller main overflow port 11 can also reduce the water flow noise generated during overflow, improving the comfort of the user environment. In addition, since the main overflow port 11 is located at the bottom of the main body 10, a smaller main overflow port 11 can save installation space at the bottom of the main body 10, improve the space utilization of the main body 10, and improve the aesthetics of the bottom of the main body 10 (a larger main overflow port 11 will reduce the aesthetics of the main body 10 and appear slightly obtrusive).

[0088] In this embodiment, the width of the main overflow port 11 may include one of the following: 2 mm, 2.1 mm, 2.13 mm, 2.15 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.43 mm, 2.5 mm, 2.54 mm, 2.6 mm, 2.7 mm, 2.76 mm, 2.79 mm, 2.8 mm, 2.9 mm, 3 mm, or any other value between 2 mm and 3 mm.

[0089] In this embodiment, the shapes of the water injection hole 04 and the main overflow port 11 can include one of the following: circular hole, rectangular hole, diamond-shaped hole, elliptical hole, etc.

[0090] Along the direction of travel of the cleaning equipment (or, in other words, along the radial direction of the circular hole when the water inlet 04 is circular), the cross-sectional area of ​​the water inlet 04 is greater than or equal to 7 square millimeters and less than or equal to 12.5 square millimeters. Specifically, the cross-sectional area of ​​the water inlet 04 may include one of the following: 7 square millimeters, 7.065 square millimeters, 7.2 square millimeters, 7.5 square millimeters, 7.8 square millimeters, 8 square millimeters, 8.12 square millimeters, 8.4 square millimeters, 8.7 square millimeters, 9 square millimeters, 10 square millimeters, 11 square millimeters, 12 square millimeters, or 12.5 square millimeters, or any other value between 7 square millimeters and 12.5 square millimeters. When the cross-sectional size of the water inlet 04 is within the above range, it ensures that the base station 90 can smoothly fill the water tank 20.

[0091] In some embodiments, the cleaning device in this embodiment further includes a cleaning component 30 and a water supply component 17. The cleaning component 30 includes at least two sets, which are disposed at the bottom of the main body 10. The water supply component 17 is disposed on the main body 10 and includes a second water inlet 171 and at least two water outlets. The second water inlet 171 is connected to the liquid storage chamber 01. Along the height direction of the main body 10, at least two water outlets 13 are disposed at the bottom of the main body 10 and are correspondingly arranged with the at least two sets of cleaning components 30. The at least two water outlets 13 are all connected to the second water inlet 171.

[0092] The second inlet 171 has a first cross-section along its own width direction, the area of ​​the first cross-section being S1, and the outlet has a second cross-section along its own width direction, the area of ​​the second cross-section being S2. The sum of S2 of at least two outlets is Y, and Y and S1 satisfy the relationship: Y < S1.

[0093] Liquid in the water tank 20 can flow into the second inlet 171 and then from the outlet 13 to the cleaning component 30 to wet it. The sum of the areas of the second cross-sections of at least two outlets 13 is less than the area of ​​the first cross-section of the second inlet 171. When the liquid flow rate of the water supply component 17 remains constant, the total cross-sectional area of ​​the outlets 13 is smaller than the cross-sectional area of ​​the second inlet 171, which increases the liquid flow rate. Liquid in the water tank 20 can flow into the cleaning component 30 more quickly through the outlets 13, thereby quickly wetting the cleaning component 30, improving the cleaning efficiency of the cleaning component 30, and providing a better user experience.

[0094] The water supply component 17 also includes a water supply channel 172, which has a connecting port 721 connected to a second water inlet 171. At least two water outlets 13 are also connected to the connecting port 721. Liquid discharged from the second water inlet 171 into the water supply channel 172 travels a path length equal to the path length from the connecting port 721 to at least one water outlet 13. In other words, the distances from the connecting port 721 to each water outlet 13 are equal, allowing the liquid to simultaneously reach at least two different water outlets 13, thus simultaneously wetting the cleaning components 30 corresponding to each water outlet 13. This ensures that the cleaning components 30 receive sufficient water within a preset time, improving the cleaning effect and efficiency of the cleaning equipment.

[0095] The water supply channel 172 includes an inlet channel 722 and at least two outlet channels 723. The inlet channel 722 is connected to the second inlet 171. The at least two outlet channels 723 are respectively located on opposite sides of the connecting port 721 and are both connected to the connecting port 721. At least two outlets 13 are correspondingly located to the at least two outlet channels 723 and are respectively located on the side of the at least two outlet channels 723 away from each other. The at least two outlet channels 723 are straight channels and / or the cross-sectional areas of the at least two outlet channels 723 along the height direction of the main body are equal. The areas of the second cross-sections of the at least two outlets 13 are equal. The outlet channels 723 can also be configured in other shapes (such as a labyrinthine channel with bends). The flow state of the liquid in the straight outlet channels 723 is more similar, which is beneficial to ensuring that the water content of different cleaning components 30 is consistent.

[0096] like Figure 12 As shown, the main body 10 includes a top shell (not shown) and a bottom shell 16. The bottom shell 16 is located at the bottom of the top shell and forms an installation space with the top shell. The water tank is located within the installation space. The water supply component 17 also includes a cover plate 173. The cover plate 173 covers the bottom shell 16 near the top shell and forms a water supply channel 172 with the bottom shell 16. A second water inlet 171 is located on the cover plate 173. The water tank 20 is located within the installation space, making full use of the internal space of the main body 10, making the placement of the water tank 20 more orderly, and also facilitating the fixing and protection of the water tank 20. The cover plate 173 of the water supply component 17 and the bottom shell 16 form a water supply channel 172. This arrangement makes full use of the space of the bottom shell 16, realizes the arrangement of the water supply channel 172, and improves the compactness of the cleaning equipment. Specifically, a groove required to form the water supply channel can be opened on the bottom shell 16, and the cover plate 173 can cover the groove to obtain the water supply channel. The water supply component 17 adopts a cover plate 173 and a bottom shell 16 in a matching manner, which makes the assembly and disassembly of the water supply component 17 more convenient and improves the ease of maintenance.

[0097] like Figure 11 As shown, the water supply component 17 also includes a connecting member 174 and a first connecting pipe 175. The connecting member 174 is located at the bottom of the main body and communicates with the outlet 13. One end of the first connecting pipe 175 communicates with the second inlet 171, and the other end of the first connecting pipe 175 communicates with the connecting member 174. The end of the first connecting pipe 175 near the connecting member 174 can be sleeved on the outside of the connecting member 174, or the first connecting pipe 175 can be inserted into the through hole of the connecting member 174, or the first connecting pipe 175 can at least partially pass through the connecting member 174 to the outlet 13. The first connecting pipe 175 can be a flexible hose, which has good flexibility and is not easy to break or tear. The connecting member 174 can be a two-way connector, with one port communicating with the outlet 13 and the other port communicating with the first connecting pipe 175.

[0098] Furthermore, in this embodiment, at least one water outlet is correspondingly arranged with at least two sets of cleaning components 30, so that water can be supplied to at least two sets of cleaning components 30 simultaneously through at least one water outlet 13. Alternatively, at least two water outlets 13 can be arranged in a one-to-one correspondence with at least two sets of cleaning components 30, that is, each set of cleaning components 30 corresponds to at least one water outlet 13. Furthermore, at least one set of cleaning components 30 can be correspondingly arranged with at least two water outlets 13, meaning that one cleaning component 30 can be supplied with water simultaneously through at least two water outlets 13, further improving the efficiency of wetting the cleaning component 30.

[0099] like Figure 13 As shown, the second embodiment of this utility model also provides a base station 90, which is used to dock cleaning equipment. The structure of the cleaning equipment is described in the first embodiment of this utility model, and will not be repeated here. Along the height direction of the base station 90, a cleaning tank 92 is provided at the bottom of the base station 90. When the cleaning component 30 of the cleaning equipment is located in the cleaning tank 92, the overflow port 03 of the cleaning equipment is connected to the cleaning tank 92. The water tank 20 of the cleaning equipment does not require a full-liquid detection device, and the water tank 20 has low cost.

[0100] In this embodiment, the base station 90 can pre-set the time for filling the water tank 20 with water according to the capacity of the water tank 20 of the cleaning equipment and the pumping speed of the first water pump 942. Even if the water tank 20 is full and overflows, it can overflow into the cleaning tank 92 through the main overflow port 11.

[0101] The third embodiment of this utility model also provides a cleaning system, such as Figure 14 The cleaning system includes cleaning equipment and a base station 90. For the specific structure of the cleaning equipment, please refer to the content provided in the first embodiment. The cleaning equipment includes a main body 10 and a water tank 20. The water tank 20 is located on the main body 10 and has a liquid storage chamber 01, a first water inlet 02, and a tank overflow port 03. The first water inlet 02 and the tank overflow port 03 are respectively connected to the liquid storage chamber 01. Along the height direction of the main body 10, there is a first height between the tank overflow port 03 and the bottom of the liquid storage chamber 01. The cleaning equipment can be selectively docked at the base station 90. Along the height direction of the base station 90, a cleaning tank 92 is provided at the bottom of the base station 90. The base station 90 also has a water injection component 94, which is connected to the first water inlet 02 to inject water into the liquid storage chamber 01. The tank overflow port 03 is configured to discharge excess water into the cleaning tank 92 when the water level in the liquid storage chamber 01 is higher than the first height.

[0102] like Figure 14As shown, the water injection assembly 94 includes a clean water tank 941, a first water pump 942, and a water injection interface 943. The first water pump 942 is located at the base station 90 and connects the clean water tank 941 and the water injection interface 943. The water injection interface 943 is located on the side wall of the bottom receiving cavity 91 of the base station 90. After the cleaning equipment returns to the base station 90, the water inlet 12 of the cleaning equipment connects to the water injection interface 943, so that the water tank 20 is connected to the clean water tank 941. When the cleaning equipment returns to the base station 90 and moves to the position where it connects to the water injection interface 943, the base station 90 can then inject water from the clean water tank 941 into the water tank 20 of the cleaning equipment through the water injection interface 943 via the first water pump 942.

[0103] When base station 90 performs maintenance on the cleaning equipment returning to the station, it can perform maintenance in the following order: dust collection—water injection—washing (mop 32)—drying and charging. Since water injection is performed before washing mop 32, the excess water discharged from the water tank 20 through the overflow port 03 after water injection will not adversely affect the subsequent washing of mop 32, thus avoiding watermarks on the surface to be cleaned when leaving the station due to excessive water content in the mop 32 after washing.

[0104] To address the issue that existing mops 32 leave noticeable watermarks when performing mopping actions after leaving the base station 90, the fourth embodiment of this utility model also provides a cleaning device. Please refer to [link / reference needed]. Figures 1 to 10 The cleaning device includes a main body 10, a cleaning component 30, and a water tank 20. A main overflow port 11 is provided at the bottom of the main body 10 along its height. This main overflow port 11 can specifically communicate with the tank overflow port 03 provided in the first embodiment. When the water tank 20 is equipped with a full-water detection device instead of a full-water overflow port 03, excess water can be discharged from the water tank 20 through the main overflow port 11 when the full-water detection device detects that the water level is higher than the first height. In this case, an interface communicating with the main overflow port 11 can be provided on the water tank 20. This interface can be located at a position above the first height or at the bottom of the water tank 20.

[0105] A water tank 20 is located on the main body 10. A liquid storage chamber 01 is provided inside the water tank 20. The liquid storage chamber 01 is connected to the main overflow port 11. When the water level in the liquid storage chamber 01 is higher than the first height along the height direction of the main body 10, the main overflow port 11 is used to discharge the water that exceeds the first height.

[0106] The cleaning component 30 is located at the bottom of the main body 10. Along the height direction of the main body 10, the cleaning component 30 has a first projection area at the bottom of the main body 10, which is offset from the main overflow port 11. That is to say, the main overflow port 11 is not corresponding to the cleaning component 30, especially the water receiving structure (such as the first through hole 3111) on the cleaning component 30, thereby preventing water overflowing from the main overflow port 11 from falling onto the mop 32 of the cleaning component 30. Therefore, after the cleaning equipment returns to the base station 90, regardless of whether the base station 90 fills the water tank 20 of the cleaning equipment first or cleans the cleaning component 30 first, the excess water in the water tank 20 can flow directly into the cleaning tank 92 of the base station 90 through the main overflow port 11. The water coming out of the main overflow port 11 will not drip onto the cleaning component 30, avoiding excessive water content in the cleaning equipment when it leaves the base station. During the cleaning work performed by the cleaning equipment when leaving the base station, no obvious watermarks will be generated on the surface to be cleaned, resulting in a better user experience.

[0107] As can be seen, in this embodiment, a main overflow port 11 is provided at the bottom of the main body 10 of the cleaning equipment. The main overflow port 11 is connected to the liquid storage chamber 01 in the water tank 20. When the water level in the liquid storage chamber 01 is higher than the first height, the main overflow port 11 is used to discharge the water exceeding the first height. The first projection area of ​​the cleaning component 30 at the bottom of the main body 10 is offset from the main overflow port 11. Therefore, after the cleaning equipment returns to the base station 90, regardless of whether the base station 90 first fills the water tank 20 of the cleaning equipment or first cleans the cleaning component 30, the excess water in the water tank 20 can flow directly into the cleaning tank 92 of the base station 90 through the main overflow port 11. The water coming out of the main overflow port 11 will not drip onto the cleaning component 30, avoiding excessive water content in the cleaning equipment when it leaves the station. During the cleaning process, the cleaning equipment will not produce obvious watermarks on the surface to be cleaned, resulting in a better user experience.

[0108] In this embodiment, the misalignment of the first projection area with the main overflow port 11 can include two scenarios: one scenario is that the edge contour line of the first projection area intersects with the edge contour line of the main overflow port 11 but does not overlap; the other scenario is that there is a gap between the edge contour line of the first projection area and the edge contour line of the main overflow port 11.

[0109] like Figure 3 and Figure 10 As shown, along the direction of travel of the cleaning equipment, the main overflow port 11 is located in front of the first projection area. Figure 13As shown, when a ramp 93 is provided at the entrance of the base station 90, the cleaning tank 92 is located in the top area of ​​the ramp 93. In this embodiment, the main overflow port 11 is located in front of the first projection area. Therefore, when the cleaning equipment returns to the base station 90 and moves along the ramp 93 to the cleaning component 30 located in the cleaning tank 92, since the cleaning equipment needs to enter the base station 90 in the opposite direction of its own working direction, the horizontal plane of the main overflow port 11 will be lower than the horizontal plane of the cleaning component 30. The water coming out of the main overflow port 11 is not easy to flow along the bottom surface of the main body 10 and the drive shaft connecting the cleaning component 30 to the cleaning component 30, further avoiding the water from the main overflow port 11 flowing to the cleaning component 30 and causing the cleaning component 30 to have a high water content.

[0110] The cleaning assembly 30 includes a bracket 31 and a mop 32. Along the height direction of the main body 10, the mop 32 is disposed on the surface of the bracket 31 away from the main body 10. When there is a gap between the first projection area and the cleaning assembly 30, the first projection area can be the projection area formed jointly by the bracket 31 and the mop 32 on the main body 10. Along the height direction of the main body 10, the first projection area is the projection of the bracket 31 onto the main body 10, and there is an installation gap between the main overflow port 11 and the first projection area. Since a water-receiving structure is typically provided on the bracket 31, connecting the water outlet 13 on the main body 10 and the mop 32, the water-receiving structure is one or more first through holes 3111 as provided in the first embodiment. This embodiment ensures that the main overflow port 11 is not aligned with the water-receiving structure by creating an installation gap between the first projection area of ​​the bracket 31 and the main overflow port 11, thereby preventing water flowing from the main overflow port 11 from flowing onto the mop 32 along the water-receiving interface.

[0111] like Figure 1 As shown, the bracket 31 in this embodiment may specifically include a tray 311 and a support ring 312. The support ring 312 surrounds the outer periphery of the tray 311 and may be made of soft rubber to tension and support the mop 32. A water-receiving structure is specifically provided on the tray 311. In some embodiments, a water-receiving structure may also be provided on the support ring 312, such as providing multiple second through holes along the axial direction of the tray 311 on the support ring 312. However, regardless of whether a water-receiving structure is provided on the tray 311 and / or the support ring 312, this embodiment ensures that there is an installation gap between the main overflow port 11 and the first projection area of ​​the bracket 31, thus ensuring that the overflowing water will not enter the mop 32. Even if the base station 90 performs the operation of cleaning the mop 32 first and then fills the water tank 20 of the cleaning equipment with water, the overflowing water will not cause the mop 32 to have a high water content when the cleaning equipment leaves the station. The projection area of ​​the outer edge of the support ring 312 away from the tray 311 on the body 10 can also at least partially overlap with the main overflow port 11, as long as the projection area corresponding to the second through hole of the support ring 312 does not overlap with the main overflow port 11.

[0112] Along the height direction of the main body 10, there is a first gap between the cleaning component 30 and the main body 10. In some cleaning equipment products, this first gap can always exist between the cleaning component 30 and the main body 10, so that the cleaning component 30 can be placed against the surface to be cleaned for cleaning work. In other cleaning equipment products, some cleaning equipment is equipped with a drive mechanism 80 that can not only drive the cleaning component 30 to rotate, but also drive the cleaning component 30 to move up and down along the height direction of the main body 10. In this case, when the cleaning equipment starts the cleaning mode, it will control the drive mechanism 80 to first lower the cleaning component 30 to a cleaning position against the surface to be cleaned, and after cleaning, it will control the drive mechanism 80 to raise the cleaning component 30 to a position away from the surface to be cleaned. At the position away from the ground, there is no first gap or the first gap between the cleaning component 30 and the main body 10, that is, when the cleaning component 30 is in the cleaning position, there will be a large gap between it and the bottom surface of the cleaning equipment. Regardless of the type of cleaning equipment mentioned above, the first gap between the cleaning component 30 and the bottom surface of the cleaning equipment, or the gap that exists during the process of the cleaning component 30 descending from the ground position to the cleaning position, can cause some low obstacles (such as electronic scales, flat household items) or obstacles within a preset height range to easily scrape against the cleaning component 30 along the gap. This can cause the cleaning component 30 to be stuck by the obstacles, resulting in a decrease in rotation speed or direct stoppage, or even the risk of it being disassembled and detached from the cleaning equipment. This risk is particularly high when the cleaning component 30 is connected to the drive mechanism 80 by magnetic attraction.

[0113] like Figure 3 and Figure 10 As shown, the cleaning device in this embodiment also includes a shielding member 40, which is disposed at the bottom of the main body 10. Along the traveling direction of the cleaning device, the shielding member 40 is located in front of the cleaning component 30, and is used to shield the first gap. The shielding member 40 can prevent obstacles from entering the first gap and scraping against the cleaning component 30, thus preventing the cleaning component 30 from being stuck or detached from the cleaning device. For example, during the process of the cleaning device moving the cleaning component 30, or during the process of the cleaning component 30 rising to a position off the ground or descending to a cleaning position under the drive mechanism 80, the shielding member 40 can block obstacles, preventing the cleaning component 30 from being scraped by obstacles.

[0114] like Figure 3 As shown, along the travel direction of the cleaning equipment, the main overflow port 11 is located between the cleaning component 30 and the shield 40, so that the main overflow port 11 is staggered in the cleaning component 30, thereby improving the utilization rate of the installation space between the cleaning component 30 and the shield 40.

[0115] The surface of the main body 10 near the cleaning component 30 includes a first region 14, within which the cleaning component 30 is located. Along the height direction of the main body 10, the distance from the first region 14 to the side of the cleaning component 30 near the main body 10 is the height of the first gap. The shielding member 40 includes a protruding structure. Along the travel direction of the cleaning device, the protruding structure protrudes from the front side of the first region 14. Along the height direction of the main body 10, the maximum distance from at least part of the protruding structure away from the bottom of the main body 10 to the first region 14 is greater than or equal to the height of the first gap, thereby ensuring that the protruding structure can shield the first gap.

[0116] Along the direction of travel of the cleaning equipment, the protruding structure includes a side wall 41 near the cleaning component 30. Along the direction of travel of the cleaning equipment, there are installation gaps between the main overflow port 11, the side wall 41, and the first projection area. Therefore, the water overflowing from the main overflow port 11 will not drip onto the cleaning component 30, nor will it easily flow along the side wall 41 of the protruding structure to other areas of the main body 10, avoiding impact on devices installed in other areas. For a base station 90 with a ramp 93 at the entrance, because there is an installation gap between the main overflow port 11 and the side wall 41, after the cleaning equipment enters the receiving cavity 91 at the bottom of the base station 90 along the ramp 93 and the cleaning component 30 is located in the cleaning tank 92 (located at the bottom of the receiving cavity 91), the horizontal plane of the main overflow port 11 will be higher than the horizontal plane of the side wall 41. This installation gap reduces the risk of water from the main overflow port 11 flowing along the side wall 41 to other areas of the main body 10.

[0117] In some embodiments, a first gap exists between the cleaning component 30 and the main body 10 along the height direction of the main body 10. The cleaning device also includes a shielding member 40 and a middle sweeping component 50. The shielding member 40 is disposed at the bottom of the main body 10. Along the traveling direction of the cleaning device, the shielding member 40 is located in front of the cleaning component 30 and has an installation gap with the cleaning component 30. The shielding member 40 is used to shield the first gap. The function of the shielding member 40 is described above. The middle sweeping component 50 is disposed at the bottom of the main body 10. Along the traveling direction of the cleaning device, the middle sweeping component 50 is located in front of the shielding member 40 away from the cleaning component 30. The middle sweeping component 50 is used to sweep away debris from the surface to be cleaned. The swept debris will be collected by a dust box installed in the main body 10.

[0118] like Figure 10As shown, along the direction of travel of the cleaning equipment, the main overflow port 11 is located on the rear side of the shield 40 away from the intermediate scanning assembly 50, and there is a gap between the main overflow port 11 and the shield 40. This ensures that the main overflow port 11 is offset from the first projection area while maintaining a greater distance between the main overflow port 11 and the intermediate scanning assembly 50. Therefore, after the cleaning equipment enters the base station 90 along the slope 93, the installation gap between the main overflow port 11 and the shield 40 prevents water from flowing along the ground of the main body 10 and the surface of the shield 40 to the intermediate scanning assembly 50 during the process of the base station 90 filling the water tank 20. This prevents water from entering the main body 10 through the installation gap between the intermediate scanning assembly 50 and the main body 10, thus avoiding short circuits, stoppages, burnouts, and other malfunctions in the driver (such as a motor) that drives the rotation of the intermediate scanning assembly 50.

[0119] like Figure 10 As shown, the cleaning assembly 30 includes at least two sets of cleaning assemblies 30 arranged along a first direction (i.e., the width direction Z of the main body 10). Along the traveling direction of the cleaning device, the main overflow port 11 is located in the gap between two adjacent sets of cleaning assemblies 30, away from the rear side of the shield 40. This not only makes full use of the space in the gap between two adjacent sets of cleaning assemblies 30 of the main body 10 to improve the space utilization rate of the bottom of the main body 10, but also ensures that the main overflow port 11 is farther away from the shield 40, thereby ensuring that the water flowing out of the main overflow port 11 will not flow along the side wall of the shield 40 to the driver of the intermediate sweeping assembly 50, thereby improving the reliability and service life of the intermediate sweeping assembly 50.

[0120] like Figure 10 As shown, along the travel direction of the cleaning equipment, the projected outer contour of the main overflow port 11 at least partially overlaps with the projected outer contour of the intermediate sweeping assembly 50, that is, the main overflow port 11 is at least partially positioned opposite the intermediate sweeping assembly 50. Along the travel direction of the cleaning equipment, the area corresponding to the shielding member 40 and the intermediate sweeping assembly 50 (as shown in the figure, the area within the dotted lines on opposite sides of the intermediate sweeping assembly 50 along the Z direction) has a vertex 401 closest to the main overflow port. The minimum distance between the main overflow port 11 and the shielding member 40 is the distance L1 between the main overflow port 11 and the vertex 401 (e.g., ...). Figure 10 As shown), the minimum distance between the first projection area of ​​the cleaning component 30 and the shielding member 40 is as follows: Figure 10As shown, L2 and L1 are greater than L2. Therefore, the distance between the main overflow port 11 and the shield 40 is greater than the distance between the cleaning component 30 and the shield 40, and thus further away from the intermediate scanning component 50. As a result, after the cleaning equipment enters the base station 90 along the slope 93, during the process of the base station 90 filling the water tank 20, the water coming out of the main overflow port 11 is less likely to flow along the ground of the main body 10 and the surface of the shield 40 to the intermediate scanning component 50, thus preventing water from entering the main body 10 through the installation gap between the intermediate scanning component 50 and the main body 10 and causing short circuits, stoppages, or other malfunctions to the driver that drives the rotation of the intermediate scanning component 50.

[0121] The inner wall surface of the shielding member 40 near the cleaning assembly 30 may include at least two arc-shaped segments 411, each corresponding to one of the at least two sets of cleaning assemblies 30, and the arc-shaped segments 411 are arranged around the outer periphery of the tray 311 of the cleaning assembly 30. In this case, the minimum distance L2 between the first projection area and the shielding member 40 is the distance between the arc-shaped segment 411 and the first projection area. The vertex 401 is located at the adjacent position between two adjacent arc-shaped segments 411. If a straight segment is provided between two adjacent arc-shaped segments 411, and if the vertex 401 is located on the straight segment, then L1 is the distance between the main overflow port 11 and the straight segment.

[0122] Along the direction of travel of the cleaning equipment, the distance between the main overflow port 11 and the edge of the main body 10 away from the shield 40 is as follows: Figure 10 As shown in the diagram, L3 and L1 are greater than L3. That is, the main overflow port 11 is located near the edge of the main body 10 away from the shield 40, which makes the distance between the main overflow port 11 and the shield 40 greater, and thus makes the main overflow port 11 farther from the intermediate scanning assembly 50.

[0123] The bottom of the main body 10 is also provided with a water outlet 13, which is connected to the water tank 20. The cleaning component 30 is provided with a water receiving structure on the side near the main body 10, which is connected to the water outlet 13. The width of the main overflow port 11 is greater than the width of the water outlet 13, so that the main overflow port 11 can discharge excess water more quickly and prevent the water tank 20 from overflowing and contaminating the internal components of the main body 10.

[0124] The width of the main overflow port 11 is greater than or equal to 2 mm and less than or equal to 3 mm. A main overflow port 11 within this range allows for more precise control of the water level in the water tank 20, preventing excessive water level fluctuations due to rapid overflow and thus reducing the actual water storage capacity of the water tank 20. This helps stabilize the water level in the water tank 20 at a predetermined level (such as at the first height level in this embodiment), ensuring sufficient water supply to the cleaning components 30 during cleaning operations. Secondly, a smaller main overflow port 11 reduces water flow noise during overflow, improving the comfort of the user environment. Furthermore, since the main overflow port 11 is located at the bottom of the main body 10, a smaller main overflow port 11 saves installation space at the bottom of the main body 10, improving the space utilization of the main body 10 and enhancing the aesthetics of the bottom of the main body 10 (a larger main overflow port 11 would reduce the aesthetics of the main body 10 and appear somewhat obtrusive).

[0125] In this embodiment, the width of the main overflow port 11 may include one of the following: 2 mm, 2.1 mm, 2.13 mm, 2.15 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.43 mm, 2.5 mm, 2.54 mm, 2.6 mm, 2.7 mm, 2.76 mm, 2.79 mm, 2.8 mm, 2.9 mm, 3 mm, or any other value between 2 mm and 3 mm.

[0126] like Figure 3 and Figure 10 As shown, the cleaning device in this embodiment also includes a walking component 60, which includes at least one walking wheel 61. At least one mounting opening 15 is also provided at the bottom of the main body 10. Along the traveling direction of the cleaning device, the mounting opening 15 is located on the front side of the cleaning component 30. At least one walking wheel 61 is correspondingly provided with at least one mounting opening 15 and is located within the mounting opening 15. Specifically, during the process of the cleaning device traveling along the slope 93 of the base station 90 to the receiving cavity 91 of the base station 90, to prevent water flowing from the main overflow port 11 from flooding the mounting opening 15 and entering the interior of the main body 10, causing damage to the drive mechanism of the walking wheel 61 or other electronic components, the main overflow port 11 and the mounting opening 15 are spaced apart along the first direction (i.e., the width direction of the main body 10 indicated by arrow Z), thereby preventing water flowing from the main overflow port 11 from flowing along the surface of the bottom of the main body 10 into the mounting opening 15 under the action of the slope 93. When there are at least two traveling wheels 61, and these at least two traveling wheels 61 are spaced apart along the first direction, the main overflow port 11 can be located between two adjacent traveling wheels 61 and staggered in the first projection area. When the intermediate sweeping assembly 50 is located between two adjacent traveling wheels 61, in addition to being spaced apart from the traveling wheels 61 along the first direction, the main overflow port 11 also needs to be located away from the intermediate sweeping assembly 50 along the traveling direction of the cleaning equipment to prevent water from flowing into the body 10.

[0127] like Figure 13 As shown, the fourth embodiment of this utility model also provides a base station 90, which is used to dock the cleaning equipment provided in the third embodiment. Along the height direction of the base station 90, a cleaning tank 92 is provided at the bottom of the base station 90. When the cleaning component 30 of the cleaning equipment is located in the cleaning tank 92, the main overflow port 11 of the cleaning equipment is connected to the cleaning tank 92. Since the first projection area of ​​the cleaning component 30 at the bottom of the main body 10 is offset from the main overflow port 11, the main overflow port 11 can directly connect to the cleaning tank 92 after the cleaning equipment returns to the base station 90. Regardless of whether the base station 90 first fills the water tank 20 of the cleaning equipment or first cleans the cleaning component 30, excess water in the water tank 20 can flow directly into the cleaning tank 92 of the base station 90 through the main overflow port 11. The water coming out of the main overflow port 11 will not drip onto the cleaning component 30, avoiding excessive water content in the cleaning equipment when it leaves the station. During the cleaning process, the cleaning equipment will not leave obvious watermarks on the surface to be cleaned, resulting in a better user experience.

[0128] 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.

[0129] 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.

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.
