[0017] In one feasible implementation, the liquid collection device further includes a negative pressure component and a one-way liquid inlet component. The negative pressure component is connected to the receiving cavity to provide a negative pressure environment for the receiving cavity, and the one-way liquid inlet component is disposed between the receiving cavity and the water collection tank.

[0018] In response to the negative pressure environment, the liquid in the water collection tank flows to the receiving cavity through the liquid inlet and the one-way liquid inlet.

[0019] In one feasible implementation, the volume of the water collection tank is greater than the volume of the trough, or the volume of the receiving cavity is greater than the volume of the water collection trough.

[0022] The wiper is provided with a flow guide component, which is arranged opposite to the liquid flow channel of the liquid collection device. The dirt scraped off by the wiper can flow to the liquid flow channel through the flow guide component.

[0023] In one possible implementation, the cleaning device further includes a drive unit disposed on the body and connected to the cleaning device;

[0024] Along the width direction of the body, the drive device can drive the cleaning device to extend from at least one side of the body, so that at least a portion of the cleaning device is exposed.

[0025] In one possible implementation, the cleaning device has a first position retracted relative to the body and a second position extended relative to the body, and the driving device is capable of driving the cleaning device to be in the first position, the second position, or between the first position and the second position;

[0033] The liquid collection device provided in this application includes a water collection tank and a cover plate. The cover plate is placed on the water collection tank to block part of the tank's surface, thereby utilizing the tension between the cover plate and the water surface to enhance the binding force on the water. When the cleaning equipment is in an obstacle-crossing or bumpy state, causing the water collection tank to vibrate or shake, the liquid flowing into the water collection tank through the liquid flow channel via the cover plate is blocked and restrained by the cover plate, thus reducing the possibility of the liquid being splashed out of the water collection tank again, which helps to improve the user experience.

[0034] The cleaning equipment and cleaning system provided in this application both include the above-mentioned liquid collection device. Therefore, the beneficial effects of the cleaning equipment and cleaning system including any one or more of the above-mentioned liquid collection devices will not be repeated here.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0073] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0076] This application provides a liquid collection device, a cleaning device, and a cleaning system. The liquid collection device is a device capable of collecting liquid flowing into it, and is used at least in the aforementioned cleaning device.

[0077] The cleaning system includes a cleaning base station and cleaning equipment, wherein the cleaning base station is used at least to house the cleaning equipment. When in operation, the cleaning equipment can clean the surface to be cleaned by direct contact.

[0078] Taking the surface to be cleaned as the ground as an example, the cleaning equipment can be a floor scrubber, a sweeping and mopping robot, or other floor cleaning tools used to clean the floor. It can be understood that the cleaning equipment can be a device that automatically performs cleaning operations in a specific area, possessing a cleaning structure capable of mopping and washing the floor, such as a roller mop. The cleaning base station can be used to maintain the aforementioned cleaning unit, such as washing the mop on the cleaning unit, charging the cleaning unit, replenishing water, and collecting dust. The cleaning base station is a base station-type structure that works in conjunction with the cleaning equipment. When the cleaning equipment starts working, it can depart from the cleaning base station and execute the corresponding cleaning task; when the cleaning equipment completes the cleaning task or in other situations requiring the cleaning task to be terminated, it can return to the cleaning base station to perform at least one or more of the following tasks: charging, replenishing water, washing, and collecting dust.

[0079] Taking a robotic mop as an example, a robotic mop can clean the floor by mopping. This function is achieved through the cleaning device and the liquid collection device. The cleaning device is used to contact the floor and mop it, while the liquid collection device is used to collect the wastewater generated during operation to further improve the cleaning efficiency. However, as the cleaning device continues to operate, when it crosses obstacles (such as climbing slopes) or collides with furniture, appliances, or walls in the workspace, the liquid in the liquid collection device may spill or leak out, causing secondary pollution to the cleaned floor. At the same time, the spilled liquid adheres to the inside of the device, which can also contaminate the internal space and affect the user experience.

[0080] In view of this, in order to solve the above problems, reduce the possibility of collected wastewater spilling again, and improve the user experience, this application provides a new liquid collection device 10, cleaning equipment 100, and cleaning system 1000.

[0081] Figure 1 This is a schematic diagram of the overall structure of the liquid collection device 10 provided in one embodiment of this application. Please refer to... Figure 1 The liquid collection device 10 includes a water collection component and a water collection tank 3. The water collection component includes a tank body 1 and a cover plate 2. The upper surface of the tank body 1 is recessed downward to form a groove, and the cover plate 2 is placed on the tank body 1.

[0082] In this embodiment, the water collection tank 3 is located on one side of the tank 1 and is fixedly connected to the tank 1. The water collection tank 3 can be detachably connected to the tank 1 by means of bonding, snap-fitting, etc., or it can be integrally formed with the tank 1.

[0083] The structure of the water collection device will be explained in detail below.

[0084] Figure 2 This is a schematic diagram of the structure of the water collecting element in a liquid collecting device provided in another embodiment of this application. Figure 3 for Figure 2 The main view, Figure 4 for Figure 2 Top view, Figure 5A for Figure 2 An exploded view of the water collection component at a certain angle. Figure 5B for Figure 2 An exploded view of the water collection component from another angle.

[0085] Please see Figure 2 , Figure 3 and Figure 4The water collection device includes a tank body 1 and a cover plate 2. The upper surface of the tank body 1 is recessed inward in the middle to form a water collection tank 101 that can hold a certain amount of liquid. The cover plate 2 is placed on the water collection tank 101. A liquid flow channel 211 is provided on the cover plate 2, through which external liquid can flow into the water collection tank 101 of the tank body 1 via the liquid flow channel 211 and the cover plate 2.

[0086] The aforementioned liquid collection device 10 can be installed inside the cleaning equipment 100. When the cleaning equipment 100 is running, the cover plate 2 is designed to partially cover the surface of the tank 1, thereby utilizing the tension between the cover plate 2 and the water surface to enhance the binding force on the water in the collection tank 101. When the cleaning equipment 100 is in a bumpy state (including obstacle crossing or vibration), the cover plate 2 can effectively reduce the possibility of water overflowing from the collection tank 101 under bumpy conditions.

[0087] The cover plate 2 can effectively prevent the liquid in the water collection tank 101 from being thrown out of the water collection tank 101 again without affecting the flow of liquid into the water collection tank 101.

[0088] It should be noted that the upper surface of the cover plate 2 is level with or slightly lower than the upper surface of the tank 1 to ensure that the design of the cover plate 2 will not increase the overall thickness of the tank 1, so as to avoid the possibility that the cover plate 2 will encroach on the internal space of the cleaning equipment 100.

[0089] Specifically, the cover plate 2 can be an integral structure, including an integrally formed plate 21 and a buckle 22. The plate 21 can be connected to the tank 1 through the buckle 22, and the liquid flow channel 211 is opened on the plate 21.

[0090] In some embodiments, the cover plate 2 is a strip structure. Along the length of the cover plate 2, the plate body 21 and the buckle 22 are connected.

[0091] Specifically, the fluid flow channel 211 can be a guide hole 21101 formed on the plate 21. The guide hole 21101 is disposed through the middle of the plate 21 of the cover plate 2, and includes at least one of different shapes such as a strip hole and a round hole. Please refer to Figure 4 The guide hole 21101 can be a strip structure with semi-circular ends along its length and two parallel or nearly parallel sides in the middle.

[0092] Specifically, the extension direction of the guide hole 21101 on the cover plate 2 is the same as the length direction of the cover plate 2. That is, the strip hole extends along the length direction of the cover plate 2, and the buckle 22 can be connected to one or both ends of the cover plate 2 body 21 along the length direction.

[0093] Please see Figure 4The length direction of cover plate 2 is consistent with the length direction of tank body 1. Cover plate 2 is a strip structure with a certain width, and correspondingly, tank body 1 is also a strip structure with a certain width. Along the width direction of tank body 1, strip-shaped guide holes 21101 are set on one side edge of cover plate 2, near its center. Of course, the arrangement position and actual opening size of guide holes 21101 can be adjusted according to the liquid outflow position, which will not be elaborated here.

[0094] Please see Figure 5A and Figure 5B The cover plate 2 can be detachably connected to the tank 1 via the buckle 22, so that the user can clean the inner wall of the tank 1 and the cover plate 2 by himself.

[0095] Specifically, the tank body 1 has a recessed water collection trough 101 structure. The upper surface of the tank body 1 is recessed downwards in the middle to form a water collection trough 101 for receiving liquid flowing in from the outside. The cover plate 2, which is placed on the tank body 1, can just cover the water collection trough 101. The outer peripheral sidewall of the cover plate 2 can be closed with the inner sidewall of the water collection trough 101 by the tank body 1, and can be in close contact with or maintain a small gap, thereby reducing the possibility of liquid in the water collection trough 101 being thrown out again.

[0096] In some embodiments, the buckle 22 may include a serpentine buckle 22, and the groove 1 is provided with a groove on the inner side wall of the portion of the water collection tank 101 that can cooperate with the buckle 22.

[0097] For example, the buckle 22 can include a first hook 221 and a second hook 222 respectively disposed at both ends of the plate 21 along its length. The slots formed on the groove 1 include a first slot 11 and a second slot 12 spaced apart along the length of the groove 1. The first hook 221 can be connected to the plate 21 through a connecting plate 223, and the second hook 222 protrudes from the end of the plate 21 facing away from the first hook 221 and is integrally formed with the plate 21.

[0098] Please see Figure 5A The connecting plate 223 has an L-shaped structure, with one end connected to the cover plate 2 and the other end having a first hook 221 and an operating protrusion. The operating protrusion is located at the free end of the connecting plate 223 and is spaced apart from the first hook 221. When the cover plate 2 is placed on the groove 1, the first hook 221 engages with the first slot 11, and the second hook 222 engages with the second slot 12.

[0099] When it is necessary to remove the cover plate 2 from the tank 1, the user can apply a certain pulling force to the connecting plate 223 by hooking the operating protrusion. The pulling force on the connecting plate 223 can cause the connecting plate 223 to undergo a recoverable elastic deformation, thereby causing the first hook 221 formed on the connecting plate 223 to disengage from the first slot 11, thus releasing the engagement between the plate 21 and the first slot 11. Then, the user can continuously pull the plate 21 to disengage the second hook 222 from the second slot 12, thereby unlocking the cover plate 2 from the tank 1 and finally removing the cover plate 2 from the tank 1. When the user needs to place the cover plate 2 on the tank 1, simply align the second hook 222 with the second slot 12, press the cover plate 2 to cover the water collection tank 101, and continue pressing the plate 21 to deform the connecting plate 223 until the first hook 221 engages with the first slot 11, thereby locking the cover plate 2 to the tank 1.

[0100] To facilitate user operation, an indicator mark is provided at one end of the plate 21 near the first hook 221. This indicator mark can be triangular. Users can determine the loading and unloading position of the cover plate 2 by observing the position of the indicator mark.

[0101] In this embodiment, the cover plate 2 can be detachably connected to the groove 1 via a snap fastener 22. In other similar embodiments, the cover plate 2 can be detachably connected to the groove 1 via a detachable fastener.

[0102] Specifically, the fasteners can be threaded structures such as bolts or screws. In this case, the cover plate 2 can be provided with at least two first connecting holes, and the tank body 1 can be provided with second connecting holes corresponding to the number and position of the first connecting holes. The second connecting holes can be threaded through holes or threaded blind holes. The fasteners pass through the first connecting holes and are threaded into the second connecting holes to achieve a fixed connection between the cover plate 2 and the tank body 1. It should be noted that the position of the second connecting holes should not affect the water collection tank 101 to prevent liquid flowing into the water collection tank 101 from leaking through the second connecting holes.

[0103] Some of the liquid flowing onto the surface of the cover plate 2 can flow directly into the water collection tank 101 through the liquid flow channel 211, while some will fall onto the upper surface of the cover plate 2 on the side opposite to the water collection tank 101. To prevent the liquid falling onto the upper surface of the cover plate 2 from flowing out of the water collection tank 101 along the upper surface of the cover plate 2, in some embodiments, the upper surface of the cover plate 2 is provided with a guide member 212 connected to the liquid flow channel 211. The guide member 212 is used to guide the liquid located on the upper surface of the cover plate 2 to flow into the liquid flow channel 211.

[0104] Specifically, the drainage element 212 includes at least one of a drainage groove and a drainage ramp.

[0105] Please see Figure 5A and Figure 5B The drainage slope is a plane or curved surface with a certain angle of inclination, and can be composed of one or more surfaces. The end of the drainage slope closest to the water collection tank 101 in the height direction points towards the liquid flow channel 211.

[0106] The flow ramp can use gravity to guide the liquid falling on the upper surface of the cover plate 21 to the flow channel 211, thereby preventing the liquid falling on the upper surface of the plate 21 from flowing to the edge of the plate 21. This allows the liquid in different areas on the upper surface of the plate 21 to flow more accurately to the flow channel 211 connected to it, and ultimately improves the flow efficiency of the liquid.

[0107] Specifically, the drainage ramps located at different positions can have different tilt angles to further increase the flow rate of the liquid.

[0108] In this embodiment, along the width direction of the tank 1, the strip-shaped guide hole 21101 is provided on the side edge of the cover plate 2 near one side of the middle part of the cover plate 2, and the flow guide slope is located on the side of the guide hole 21101 near the middle part of the cover plate 2.

[0109] Please see Figure 5A and Figure 5B The liquid flow channel 211 is a strip-shaped hole. The flow-guiding slope is closer to the corresponding side edge of the guide hole 21101 and lower than the side edge of the opposite side, so that the flow-guiding component 212 is tilted towards the flow direction of the external liquid, so that the guide hole 21101 can better receive and guide the liquid into the water collection tank 101.

[0110] In other similar embodiments, the flow guide 212 may include a flow guide groove, which is a groove-shaped structure formed on the upper surface of the plate 21. It can provide a specific flow channel for the fluid to increase the flow area and guide the liquid falling on the upper surface of the plate 21 to flow into the liquid flow channel 211.

[0111] Specifically, the depth and width of the drainage channel can be adjusted as needed.

[0112] In other similar embodiments, the diversion member 212 may include both a diversion ramp and a diversion channel. In this case, at least part of the sidewall of the diversion channel includes the diversion ramp. The diversion ramp may be a plane or a curved surface with a certain inclination angle and its end in the height direction near the water collection tank 101 points towards the liquid flow channel 211, so as to further improve the diversion effect of the diversion member 212.

[0113] In addition to the flow guide hole 21101, in other embodiments, the flow channel 211 may also include a flow guide notch 21102.

[0114] Please see Figure 6 , Figure 6This is a schematic diagram of the cover plate 2 in a liquid collection device 10 provided in another embodiment of this application. Part of the outer peripheral sidewall of the cover plate 2 is recessed inward to form a flow guiding notch 21102.

[0115] Specifically, along the thickness direction of the cover plate 2, part of the circumferential sidewalls of the cover plate 2 are recessed inward. At this time, the recessed sidewalls can be used to form a flow guide gap 21102 to provide a better guiding path for the fluid.

[0116] Please see Figure 6 A flow-guiding notch 21102 is formed on the plate 21 of the cover plate 2. Along the length of the cover plate 2, the opening size of the flow-guiding notch 21102 is smaller than the length of the cover plate 2. For example, the length of the cover plate 2 is defined as a first length, and the length of the flow-guiding notch 21102 is defined as a second length, which is smaller than the first length. However, to ensure that the flow-guiding notch 21102 has sufficient size to guide the liquid flow, the second length can be set to be greater than half the first length.

[0117] Similarly, along the width direction of the cover plate 2, the size of the flow guide notch 21102 can be greater than one-third of the width of the cover plate 2 and less than two-thirds of the width of the cover plate 2.

[0118] It should be noted that, in order to prevent the liquid in the water collection tank 101 from being thrown out directly through the guide notch 21102, the guide notch 21102 is generally set on the side of the cover plate 21 away from the drain device.

[0119] Along the length of the cover plate 2, if the size of the liquid flow channel 211 is too large, it may affect the overall strength of the cover plate 2. In order to reduce the processing cost of the cover plate 2 while ensuring that the cover plate 2 has sufficient structural strength, a partition 213 can be provided in the liquid flow channel 211. The partition 213 can divide the liquid flow channel 211 into a first channel 2111 and a second channel 2112 along the length of the liquid flow channel 211. The first channel 2111 can be either the guide hole 21101 or the guide notch 21102, and the second channel 2112 can also be either the guide hole 21101 or the guide notch 21102.

[0120] For example, both the first channel 2111 and the second channel 2112 can be configured as flow guide holes 21101. See also... Figure 7 , Figure 7 This is a schematic diagram of the structure of the cover plate 2 in the liquid collection device 10 provided in another embodiment of this application.

[0121] Specifically, the liquid flow channel 211 of the cover plate 2 is a guide hole 21101, including a first channel 2111 and a second channel 2112 arranged at intervals. Both the first channel 2111 and the second channel 2112 are strip-shaped hole structures extending along the length direction of the cover plate 2. Figure 5A and Figure 5B Compared to the single-strip hole structure shown, the partition 213 located between the first channel 2111 and the second channel 2112 can serve as a reinforcing rib, effectively enhancing the structural strength of the plate 21 and ultimately reducing the possibility of the plate 21 bending or breaking under external force.

[0122] In addition, the first channel 2111 and the second channel 2112 arranged at intervals above can help the cover plate 2 to better adapt to different usage scenarios, so that the liquid collection device 10 can be matched with liquid drainage devices in different positions to meet the differentiated needs of multiple scenarios.

[0123] In some embodiments, along the length of the plate 21, the first channel 2111 and the second channel 2112 are spaced apart and are asymmetrical holes. That is, the partition 213 is offset towards one end relative to the length of the liquid flow channel 211, so that the dimensions of the first channel 2111 and the second channel 2112 are different in the length direction. For example, the length of the first channel 2111 is greater than the length of the second channel 2112.

[0124] Of course, in other similar embodiments, at least one of the first channel 2111 and the second channel 2112 may also be a flow guide notch 21102.

[0125] Figure 8 This is an exploded view of a liquid collection device provided in one embodiment of this application. Figure 9 for Figure 8 Internal structure diagram of CIMC water tank 3 Figure 10 for Figure 9 A cross-sectional structural diagram. Figure 11 This is a partial structural cross-sectional view of a liquid collection device provided in one embodiment of this application.

[0126] Please see Figure 8 The liquid collection device 10 provided in this application embodiment has a liquid collection tank 3 with a receiving cavity 301 for storing liquid. The liquid collection tank 3 has a liquid inlet 302 that communicates with the receiving cavity 301. The receiving cavity 301 can be fluidly connected to the water collection tank 101 through the liquid inlet 302. Liquid flowing into the water collection tank 101 can flow into the liquid collection tank 3 through the liquid inlet 302 to ensure that the liquid flowing into the water collection tank 101 will not remain in the water collection tank 101, avoiding problems such as liquid overflow and leakage in the water collection tank 101 due to excessive liquid flow. At the same time, it can also realize the collection and storage of liquid.

[0127] The volume of the water collection tank 3 is greater than the volume of the tank 1. In other words, the volume of the receiving cavity 301 is greater than the volume of the water collection tank 101. This ensures that the water collection tank 3 can continuously collect and store the liquid discharged from the water collection tank 101 within a certain range.

[0128] Specifically, the water collection tank 3 is integrally formed with the tank body 1 and is located on one side of the tank body 1 in the width direction. The liquid inlet 302 is located at the end of the water collection tank 3 facing the water collection tank 101. Liquid flowing into the water collection tank 101 can flow into the receiving cavity 301 of the water collection tank 3 through the liquid inlet 302.

[0129] In some embodiments, in the horizontal direction, the liquid flow channel 211 is offset relative to the geometric center of the cover plate 2 toward the side away from the water collection tank 3.

[0130] Please see Figure 8 At this time, the liquid flow channel 211 includes a strip-shaped guide hole 21101. Along the width direction of the tank 1, the guide hole 21101 on the cover plate 2 is offset relative to the center of the cover plate 2 towards the side away from the water collection tank 3. Of course, in other similar embodiments, the liquid flow channel 211 can also be set to be offset towards the side of the cover plate 2 closer to the water collection tank 3, or exactly located in the middle of the width direction of the cover plate 2. The opening position of the liquid flow channel 211 needs to be able to receive the liquid discharged by the drainage device well. This embodiment does not limit the actual arrangement position and size of the liquid flow channel 211.

[0131] Please see Figure 8 The water collection tank 3 includes a separate tank body and a flip-top. When the flip-top is on the tank body, the tank body and the flip-top define the aforementioned receiving cavity 301. The receiving cavity 301 of the water collection tank 3 is located on one side of the tank body 1 and its position is not lower than that of the tank body 1. To ensure that the liquid in the water collection tank 101 can flow smoothly into the receiving cavity 301, in some embodiments, the liquid collection device 10 also includes a negative pressure component and a one-way liquid inlet component 5. The negative pressure component is connected to the receiving cavity 301 to provide a negative pressure environment for the receiving cavity 301. The one-way liquid inlet component 5 is disposed between the receiving cavity 301 and the water collection tank 101 (or the liquid inlet 302). When the negative pressure component is activated, it can create a certain negative pressure environment in the receiving cavity 301. In response to the negative pressure environment in the receiving cavity 301, the liquid in the water collection tank 101 flows to the receiving cavity 301 through the liquid inlet 302 and the one-way liquid inlet component 5.

[0132] The negative pressure component can be installed inside the receiving cavity 301 of the water collection tank 3, or it can be installed outside the water collection tank 3 and kept in communication with the receiving cavity 301. This embodiment does not limit the specific arrangement position of the negative pressure component.

[0133] The one-way inlet component 5 can be a one-way valve, such as a duckbill valve or a cross valve.

[0134] Please see Figure 8 and Figure 11The one-way inlet 5 is located within the receiving cavity 301 and is a cross valve with a silicone head, wherein the silicone head has a cross-shaped cut. This cut is closed in its natural state, but opens when subjected to a certain fluid pressure, allowing liquid to pass through.

[0135] Of course, the aforementioned silicone head can also be made of other elastic materials, such as rubber.

[0136] When the negative pressure device is not activated, the cross-shaped cut of the cross valve will be tightly closed by the elasticity of the silicone material, thereby preventing fluid from passing through, especially preventing the liquid in the receiving cavity 301 from flowing back into the collection tank 101. When the negative pressure device is activated, a certain negative pressure environment will be formed in the receiving cavity 301. This negative pressure will cause the cross-shaped cut of the silicone head to be slightly open. At this time, the liquid in the collection tank 101 can flow synchronously from the inlet 302 to the silicone head and flow into the receiving cavity 301 through the silicone head. When the negative pressure device is closed, the silicone head returns to the closed state.

[0137] Please see Figure 8 and Figure 11 The cavity 301 is also equipped with a negative pressure connector 4. At this time, the negative pressure connector is located outside the cavity 301 and is connected to the air outlet of the cavity 301 (not marked in the figure).

[0138] The negative pressure connector 4 can be used to connect the air inlet of the negative pressure component and the air outlet of the receiving cavity 301 to achieve a sealed connection between the negative pressure component and the receiving cavity 301. When the negative pressure component is working, the gas in the receiving cavity 301 can be extracted through the negative pressure connector 4 to form a negative pressure environment within the receiving cavity 301. The structure and connection method of the negative pressure connector 4 have been disclosed in related technologies and will not be described in detail here.

[0139] In other similar embodiments, the tank 1 and the water collection tank 3 can also be configured as separate structures as needed.

[0140] Specifically, the liquid collection device 10 also includes a liquid guide pipe connecting the receiving cavity 301 of the water collection tank 3 and the water collection tank 101 of the tank body 1. The water collection tank 3 has a liquid inlet 302. One end of the liquid guide pipe is connected to the receiving cavity 301 through the liquid inlet 302, and the other end is connected to the water collection tank 101 to guide the liquid in the water collection tank 101 to flow to the receiving cavity 301.

[0141] When the water collection tank 3 is located below the tank body 1, the liquid in the water collection trough 101 can flow into the receiving cavity 301 of the water collection tank 3 under the action of gravity. However, this structure results in an excessively thick liquid collection device 10. When the height of the water collection tank 3 is not lower than that of the tank body 1, in order to promptly pump the sewage in the water collection trough 101 into the water collection tank 3, a negative pressure component as described above can be installed inside the water collection tank 3, or a negative pressure component can be connected to the water collection tank 3. Under the negative pressure provided by the negative pressure component, the liquid in the water collection trough 101 can be pumped into the water collection tank 3 through the liquid guide pipe.

[0142] In other similar embodiments, a one-way valve may be installed on the liquid guide pipe, or a one-way valve connected to the liquid guide pipe may be installed in the receiving cavity 301. The negative pressure component can be connected to the water collection tank 3 through a pipe or directly. When it is working, it can draw negative pressure into the water collection tank 3. Under the guidance of the one-way valve, the liquid in the water collection tank 101 can be drawn into the receiving cavity 301 of the water collection tank 3 through the liquid guide pipe.

[0143] Specifically, the negative pressure component can be set as a negative pressure pump.

[0144] Please see Figure 8 The water collection tank 3 is also equipped with a filter element 6 in its receiving cavity 301. The filter element 6 can be used to filter the liquid flowing into the receiving cavity 301 through the liquid inlet 302 to separate the liquid and solids. Along the direction of liquid flow, the filter element 6 is located downstream of the one-way liquid inlet 5.

[0145] In some embodiments, the filter element 6 is detachably connected to the water collection tank 3 and located within the receiving cavity 301. This structure facilitates user self-cleaning of the inner wall of the water collection tank 3 and the filter element 6.

[0146] Specifically, along the height direction of the water collection tank 3, the filter element 6 can divide the receiving cavity 301 into a first receiving space and a second receiving space space spaced apart along the height direction, with the first receiving space space located above the filter element 6. The outlet of the one-way liquid inlet 5 is connected to the first receiving space. Some of the liquid flowing into the first receiving space through the one-way liquid inlet 5 can pass through the filter element 6 and flow into the second receiving space, while the dirt flowing into the first receiving space simultaneously with the liquid will remain in the first receiving space due to the obstruction of the filter element 6. Alternatively, along the horizontal direction, the filter element 6 can divide the receiving cavity 301 into a first receiving space and a second receiving space space spaced apart along the horizontal direction, with the first receiving space space located on the side of the filter element 6 closer to the one-way liquid inlet 5 in the horizontal direction, and the second receiving space space located on the other side of the filter element 6 opposite to the one-way liquid inlet 5 in the horizontal direction.

[0147] Please see Figure 8 , Figure 9 and Figure 10The filter element 6 has a perforation 322 for installing the one-way liquid inlet element 5, and the water collection tank 3 also has an annular limiting element for accommodating the one-way liquid inlet element 5. One end of the annular limiting element is connected to the liquid inlet 302, and the other end is connected to the perforation 322. When the filter element 6 is installed in the receiving cavity 301 of the water collection tank 3, the one-way liquid inlet element 5 installed on the perforation 322 can be inserted into the annular limiting element.

[0148] Please see Figure 8 and Figure 11 The cavity 301 is also equipped with a liquid level detection element 7 and a drain element 8. The liquid level detection element 7 is used to detect the liquid level height in the cavity 301, and the drain element 8 is used to drain the liquid in the cavity 301.

[0149] Specifically, the liquid level detection element 7 can be configured to include one of the following sensors: ultrasonic liquid level sensor, float-Hall level sensor, photoelectric liquid level sensor, and electrode liquid level sensor. Taking the float-Hall level sensor as an example, the water collection tank 3 is equipped with a track to limit the rise and fall path of the float, and a Hall sensor that works in conjunction with the float is also installed in the water collection tank 3. The float has a certain magnetic property. When the liquid level in the water collection tank 3 changes, the float moves up and down along the track. The Hall sensor can generate a corresponding signal by detecting the change in magnetic field strength, and determine the liquid level height at this time by analyzing the signal.

[0150] Specifically, the drain component 8 can include a drain pump, a lever-type drain structure, etc. Taking the lever-type drain structure as an example, this structure is located outside the receiving cavity 301 and includes a lever and a seal. Please refer to [link / reference]. Figure 11 The lever is hinged to the outer wall of the water collection tank 3. One end of the lever is sealed to a drain hole on the water collection tank 3 through a seal, and the other end points out of the water collection tank 3. When an external force is applied to the end of the lever pointing out of the water collection tank 3, the lever will swing around the hinge axis under the action of the external force. At this time, the other end of the lever swings in the opposite direction and drives the seal away from the drain hole. At this time, the liquid in the receiving cavity 301 can be discharged through the drain hole.

[0151] Of course, the water collection tank 3 also has a liquid delivery pipe for conveying clean water in its accommodating cavity 301, so as to further improve the integration of the liquid collection device 10 and minimize the space occupied by the liquid collection device 10 in the internal space of the cleaning equipment 100.

[0152] It is understood that the liquid collection device 10 provided in this application embodiment includes a connected water collection component and a water collection tank 3. The water collection component includes a tank body 1 and a cover plate 2. The cover plate 2 is placed on the tank body 1, and the tension between the cover plate 2 and the water surface can be used to enhance the binding force on the water. When the cleaning equipment 100 is in an obstacle-crossing state or a bumpy state, which may cause the tank body 1 to vibrate or shake, the liquid flowing into the water collection tank 101 of the tank body 1 through the liquid flow channel 211 and the cover plate 2 will be blocked and bound by the cover plate 2, thereby reducing the possibility of the liquid being thrown out of the water collection tank 101 again, which helps to improve the user experience.

[0153] Based on the same concept, this application also provides a cleaning device 100, please refer to... Figure 12 , Figure 12 This is a schematic diagram of the overall structure of the cleaning equipment 100 provided in the embodiments of this application.

[0154] Specifically, the cleaning equipment 100 includes a body 20, a cleaning device 30, and a liquid collection device 10, with the liquid collection device 10 located inside the body 20. Figure 12 (Not shown in the drawing), the cleaning device 30 is installed on the body 20 and partially exposed relative to the body 20.

[0155] As the machine body 20 moves along the surface to be cleaned, the cleaning device 30 can be exposed relative to the lower surface of the machine body 20 and come into contact with the surface to be cleaned, thereby achieving cleaning treatment of the surface to be cleaned. The liquid collection device 10 is configured to collect the wastewater generated by the cleaning device 30.

[0156] Please see Figure 12 The cleaning equipment 100 is a self-propelled device. For example, a robot vacuum cleaner or a robot mop.

[0157] Figure 13 This is a schematic diagram showing the relative positions of the cleaning device 30 and the liquid collection device 10 in the height direction of the cleaning equipment 100 provided in this application embodiment. Figure 14 This is a partial structural diagram of the cleaning device 30 in the cleaning equipment 100 provided in this embodiment of the application. Figure 15 for Figure 14 A schematic diagram of the cross-sectional structure. Figure 16 for Figure 14 A schematic diagram of the structure of the middle wiper component 320.

[0158] Please see Figure 13 and Figure 14In this embodiment, the cleaning device 30 includes a cleaning component 310 and a squeegee 320 connected together. The cleaning component 310 is rotatably mounted on the body 20 around its own axis. The squeegee 320 is located outside the cleaning component 310 and one end is in contact with the cleaning component 310, used to scrape off dirt adhering to the cleaning component 310 when the cleaning component 310 rotates. The squeegee 320 is provided with a drainage member 321, which is disposed opposite to the liquid flow channel 211 of the liquid collection device 10. The dirt scraped off by the squeegee 320 can flow to the liquid flow channel 211 through the drainage member 321.

[0159] At least a portion of the liquid collection device 10 is located below the wiper 320.

[0160] Please see Figure 13 and Figure 14 Along the height direction, the higher end of the wiper 320 contacts and presses against the axial outer wall of the cleaning component 310, causing the wiper 320 to abut against the cleaning component 310. The lower end is positioned above the liquid collection device 10 and is directly opposite the liquid flow channel 211 of the liquid collection device 10. At this time, there is a certain amount of interference between the wiper 320 and the cleaning component 310. As the cleaning component 310 rotates, the wiper 320 can scrape away the sewage adsorbed inside the cleaning component 310 by wiping its surface. At the same time, it can also peel off the garbage and dirt attached to the surface of the cleaning component 310. The dirt can flow to the lower end of the wiper 320 under the action of the sewage and flow to the liquid collection device 10 under the guidance of the drainage member 321.

[0161] Please see Figure 14 The drainage component 321 can be a perforated structure penetrating the wiper component 320, which can be a strip-shaped hole or a round hole. Of course, in other similar embodiments, the strip-shaped drainage component 321 can be a groove-shaped structure or a tubular structure connecting the upper and lower surfaces of the wiper component 320, etc., as needed.

[0162] Please see Figure 15 and Figure 16 The cleaning component 310 has a cylindrical structure, and the wiper component 320 extends along the axial direction of the cleaning component 310 and is located on the outer side of one radial end of the cleaning component 310. The wiper component 320 is generally similar to a funnel or trumpet shape, with the larger opening end abutting against the axial outer wall of the cleaning component 310, and the smaller opening end forming a perforated drainage component 321.

[0163] Specifically, the wiper component 320 can be a one-piece molded structure, wherein the surface of the wiper component 320 near the cleaning component 310 abuts against the cleaning component 310 and has multiple perforations 322.

[0164] Multiple perforations 322 are spaced apart along the length of the wiper 320. As the cleaning member 310 rotates, the end of the wiper 320 that abuts against the surface of the cleaning member 310 can rotaryly scrape away dirt from the surface of the cleaning member 310, while simultaneously squeezing out wastewater adsorbed inside the cleaning member 310 by pressing it. The squeezed-out wastewater can flow through the perforations 322 to the inner wall of the wiper 320, and then flow along the inner wall of the wiper 320 to the drainage member 321 under the action of gravity.

[0165] Figure 17 This is an assembly diagram of the cleaning device 30 and the drive device 40 in the cleaning equipment 100 provided in the embodiments of this application. Figure 18 for Figure 17 A partial structural diagram. Figure 19A This is a bottom view of the cleaning device 100 provided in the embodiments of this application when the cleaning device 30 is in the first position. Figure 19B A bottom view of the cleaning device 100 provided in this embodiment of the application when the cleaning device 30 is in the second position. Figure 20A for Figure 19A A schematic diagram showing the relative positions of the cleaning device 30 and the liquid collection device 10. Figure 20B for Figure 19B A schematic diagram showing the relative positions of the cleaning device 30 and the liquid collection device 10.

[0166] Please see Figure 17 and 18 The cleaning device 100 provided in this application embodiment also includes a drive device 40, which is disposed on the body 20 and connected to the cleaning device 30. The cleaning device 30 can be displaced relative to the body 20 under the drive of the drive device 40.

[0167] Specifically, along the width direction of the body 20, the drive device 40 can drive the cleaning device 30 to extend from at least one side of the body 20, so that at least a portion of the cleaning device 30 is exposed.

[0168] It should be noted that, driven by the drive device 40, the cleaning component 310 and the wiping component 320 in the cleaning device 30 move synchronously. Therefore, when at least a portion of the cleaning device 30 is exposed, at least a portion of the cleaning component 310 can be exposed relative to the body 20.

[0169] The drive device 40 includes a drive motor 410 and a transmission assembly. The transmission assembly connects the output end of the drive motor 410 and the cleaning device 30 so that the cleaning device 30 can be displaced under the drive of the drive motor 410.

[0170] For details, please refer to Figure 18The transmission assembly includes a gear 420 and a rack 430 that mesh with each other. The gear 420 is connected to the output end of the drive motor 410, and the rack 430 is fixedly connected to the cleaning device 30. When the drive motor 410 is started, the gear 420 and the rack 430 cooperate to drive the cleaning device 30 to move back and forth linearly along a set path.

[0171] The cleaning device 30 has a first position retracted relative to the body 20 and a second position extended relative to the body 20. Driven by the drive device 40, the cleaning device 30 can be positioned relative to the body 20 in the first position, the second position, and between the first and second positions.

[0172] The drive device 40 can drive the cleaning device 30 to move from the first position to the second position so that the cleaning device 30 can extend relative to the body 20 in the width direction; or, the drive device 40 can also drive the cleaning device 30 to move from the second position to the first position so that the cleaning device 30 can retract relative to the body 20 in the width direction.

[0173] When the cleaning device 30 is in the first position, please refer to Figure 19A When the cleaning device 30 is in the second position, please refer to... Figure 19B .

[0174] When the cleaning device 30 switches between the first position and the second position, in order to ensure that the sewage discharged by the drainage component 321 of the wiper 320 can always flow to the liquid flow channel 211 of the liquid collection device 10, the liquid flow channel 211 can be set as a long strip structure that can correspond to the drainage component 321.

[0175] It should be noted that the extension direction of the liquid flow channel 211 is consistent with the displacement path of the cleaning device 30. Specifically, along the direction of the displacement path of the cleaning device 30, the liquid flow channel 211 has a first length, which is greater than the length of the displacement path of the cleaning device 30, to ensure that as the cleaning device 30 moves, the liquid discharged from it can always flow into the liquid flow channel 211.

[0176] Specifically, the liquid flow channel 211 is configured as a strip structure extending from the displacement path of the cleaning device 30. Under normal operating conditions, the orthographic projection of the drainage component 321 on the horizontal plane can be partially aligned with the orthographic projection of the liquid flow channel 211 on the horizontal plane, or the orthographic projection of the drainage component 321 on the horizontal plane can be located within the orthographic projection of the liquid flow channel 211 on the horizontal plane.

[0177] Alternatively, in this embodiment, the fluid flow channel 211 may be provided to include a first channel 2111 and a second channel 2112 spaced apart along the displacement path of the cleaning device 30, with the first channel 2111 corresponding to a first position of the cleaning device 30 and the second channel 2112 corresponding to a second position of the cleaning device 30.

[0178] A partition 213 is provided within the liquid flow channel 211, dividing it along its length into a first channel 2111 and a second channel 2112 that are spaced apart. (See also...) Figure 20A and Figure 20B The liquid flow channel 211 is a guide hole 21101, which includes a perforated first channel 2111 and a perforated second channel 2112 arranged at intervals. When the cleaning device 30 is in the first position, the guide member 321 of the wiper 320 is arranged opposite to the first channel 2111, and at least part of the dirt scraped by the wiper 320 (i.e., the wastewater generated by the cleaning device 30) can fall into the first channel 2111, and the rest can fall onto the upper surface of the cover plate 2 and flow to the first channel 2111 through the guide member 212; when the cleaning device 30 is in the second position, the guide member 321 of the wiper 320 is arranged opposite to the second channel 2112, and at least part of the dirt scraped by the wiper 320 can fall into the second channel 2112, and the rest can fall onto the upper surface of the cover plate 2 and flow to the second channel 2112 through the guide member 212.

[0179] The first channel 2111 and the second channel 2112 mentioned above can be referred to the previous text and will not be repeated here. That is to say, the straight line of the displacement path of the cleaning device 30 is parallel to the length direction of the cover plate 2.

[0180] In this embodiment, when the cleaning device 30 is in the first position, the corresponding cleaning device 100 is in normal cleaning mode; when the cleaning device 30 is in the second position, the corresponding cleaning device 100 is in edge cleaning mode. The liquid flow channel 211 includes a first channel 2111 and a second channel 2112, which can adapt to different working states of the cleaning device 30 without affecting the overall strength of the cover plate 2 and the processing cost.

[0181] Specifically, the flow rate of wastewater generated when the cleaning device 30 is in the first position can be set to be greater than the flow rate of wastewater generated when the cleaning device 30 is in the second position.
