[0052] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0053] The base station 10 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0054] like Figures 1-16As shown, the base station 10 according to an embodiment of the present invention includes a housing 100, a water treatment module 20, a clean water collection module 600, and a dust collection module 130.

[0055] The housing 100 is provided with a mating part, which is suitable for mating with the sweeping robot 90. When the sweeping robot 90 is mated with the mating part, the base plate of the sweeping robot 90 can be cleaned, charged or otherwise operated through the base station 10.

[0056] The unit is equipped with a sewage inlet, a dust inlet 112, and a clean water outlet. The sewage collected by the sweeping robot 90 is suitable for being discharged into the base station 10 through the sewage inlet. The garbage collected by the sweeping robot 90 can be discharged into the base station 10 through the dust inlet 112. The clean water in the base station 10 can flow to the sweeping robot 90 through the clean water outlet to clean the bottom plate of the sweeping robot 90. Furthermore, the clean water in the base station 10 can clean the rag on the bottom plate of the sweeping robot 90.

[0057] The water treatment module 20 is located in the housing 100. The water treatment module 20 is connected to the sewage inlet to receive the sewage collected by the sweeping robot 90. The water treatment module 20 can also treat the sewage to obtain clean water.

[0058] A clean water collection module 600 is located on the housing 100. The clean water collection module 600 is connected to the water treatment module 20 and the clean water outlet. The clean water produced by the water treatment module 20 can be stored in the clean water collection module 600. The clean water in the clean water collection module 600 is suitable for being discharged from the clean water outlet to the sweeping robot 90 to clean the bottom plate of the sweeping robot 90.

[0059] The dust collection module 130 is located on the housing 100. The dust collection module 130 is connected to the dust inlet 112 to receive the garbage collected by the sweeping robot 90, so as to avoid the garbage collected by the sweeping robot 90 remaining at the mating parts and to prevent the garbage at the mating parts from causing secondary pollution to the sweeping robot 90. This also facilitates the base to clean the bottom plate of the sweeping robot 90.

[0060] In addition, by collecting the waste in the dust collection module 130, users only need to clean the waste in the dust collection module 130 without having to clean the mating parts, which makes the operation more convenient for users and improves the user experience.

[0061] Specifically, the clean water collection module 600 can collect clean water and use the collected clean water to clean the bottom plate of the sweeping robot 90. The water treatment module 20 can receive the sewage collected by the sweeping robot 90 and treat the sewage to produce clean water. The produced clean water can replenish the collection module 600. The dust collection module 130 can receive the garbage collected by the sweeping robot 90.

[0062] This method reduces the amount of contaminants remaining at the mating parts, ensuring their cleanliness. This facilitates cleaning and maintenance of the robot vacuum's (90) base plate and reduces the frequency of cleaning the base station (10), thus improving the user experience.

[0063] Therefore, the base station 10 according to the embodiments of the present invention can clean the bottom plate of the sweeping robot 90, collect the sewage left by the sweeping robot 90, and collect the garbage left by the sweeping robot 90, which has the advantages of improving the automation of the base station 10, reducing the number of times the user cleans the base station 10, and improving the user experience.

[0064] The base station 10 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0065] like Figures 1-16 As shown, the base station 10 according to an embodiment of the present invention includes a housing 100, a water treatment module 20, a clean water collection module 600, and a dust collection module 130.

[0066] In some embodiments of the present invention, the water treatment module 20 includes a wastewater tank 210, a heating component, and a cooling module 320. The wastewater tank 210 is connected to a wastewater inlet and is used to receive wastewater. Wastewater collected by the sweeping robot 90 can flow into the wastewater tank 210 through the wastewater inlet. The heating component is used to heat the wastewater to treat the wastewater in the wastewater tank 210, causing the water in the wastewater tank 210 to absorb heat and turn into steam, thereby separating the water and pollutants in the wastewater tank 210 and extracting clean water from the wastewater tank 210.

[0067] Specifically, the heating component can heat the sewage in the sewage tank 210. The water in the sewage tank 210 evaporates into steam after being heated. The steam is discharged through the steam outlet 212 of the sewage tank 210. The cooling module 320 can cool the steam discharged from the steam outlet 212, so that this part of the steam can release heat and liquefy into condensate to obtain clean water.

[0068] In some optional embodiments of the present invention, the sewage tank 210 is provided with a dust discharge port 211, which is connected to the dust collection module 130. The garbage inside the sewage tank 210 is discharged to the dust collection module 130 through the dust discharge port 211. By discharging the garbage inside the sewage tank 210, the sewage tank 210 can be cleaned to reduce the garbage content inside the sewage tank 210, so that the sewage tank 210 can store more sewage. At the same time, it is convenient for the water treatment module 20 to treat the sewage in the sewage tank 210 in the future, which can improve the efficiency of the water treatment module 20 in producing clean water.

[0069] In addition, by discharging the garbage inside the sewage tank 210 to the dust collection module 130 through the dust outlet 211 and treating the water in the sewage tank 210 using the water treatment module 20, the amount of garbage and sewage in the sewage tank 210 can be reduced, thereby reducing the number of times users need to clean or replace the sewage tank 210 and improving the user experience.

[0070] In some specific embodiments of the present invention, such as Figure 6 As shown, the water treatment module 20 also includes a rotatable crusher 330. The crusher 330 is located inside the sewage tank 210 to crush the internal materials to obtain waste. By crushing the internal materials inside the sewage tank 210, the internal materials inside the sewage tank 210 can be turned into smaller waste, thereby ensuring that the waste can smoothly enter the dust collection module 130 from the dust discharge port 211, so as to avoid the dust discharge port 211 being blocked due to the excessive size of the internal materials, which would affect the discharge of waste from the sewage tank 210.

[0071] Specifically, when the water treatment module 20 treats the sewage in the sewage tank 210 to obtain clean water, the heating component heats the sewage in the sewage tank 210. The water in the sewage tank 210 absorbs heat and turns into water vapor. Meanwhile, the waste in the sewage tank 210 accumulates to form larger internal materials. These larger internal materials cannot be discharged into the dust collection module 130 through the dust discharge port 211. Therefore, the crushing component 330 is needed to crush the internal materials to obtain smaller waste, avoiding blockage of the dust discharge port 211 and ensuring that the waste can be smoothly discharged into the dust collection module 130 from the dust discharge port 211.

[0072] In some specific embodiments of the present invention, the base station 10 further includes a first switching valve 510, which is connected to the dust discharge port 211, the dust inlet 112 and the dust collection module 130 respectively. The first switching valve 510 is activated to switch the connection between the dust discharge port 211 and the dust inlet 112 and the dust collection module 130.

[0073] Specifically, when the first switching valve 510 opens the dust outlet 211, it closes the dust inlet 112, allowing the waste in the wastewater tank 210 to be discharged into the dust collection module 130 through the dust outlet 211. When the first switching valve 510 opens the dust inlet 112, it closes the dust outlet 211, allowing the waste collected by the sweeping robot 90 to be discharged into the dust collection device through the dust inlet 112.

[0074] In some specific embodiments of the present invention, the first switching valve 510 is provided with an air inlet 511. The air inlet 511 is connected to the sewage tank 210 through an air pipe 430 to replenish the sewage tank 210 with air, so that the air can flow smoothly in the sewage tank 210, thereby allowing the steam in the sewage tank 210 to flow from the steam outlet 212 to the cooling module.

[0075] Specifically, when the heating component heats the water in the sewage tank 210, the pressure inside the sewage tank 210 is relatively high. At this time, the air flow inside the sewage tank 210 is relatively low. Outside air can enter the air pipe 430 through the air inlet 511 and flow along the air pipe 430 to the sewage tank 210, so that the air inside the sewage tank 210 can flow smoothly. In turn, the steam generated by the heating component can flow smoothly from the steam outlet 212 to the cooling module 320.

[0076] In some specific embodiments of the present invention, the air duct 430 is used to connect the dust discharge port 211 and the dust collection module 130. The garbage in the sewage tank 210 can enter the air duct 430 through the dust discharge port 211 and enter the dust collection device along the air duct 430 to discharge the garbage in the sewage tank 210.

[0077] In some embodiments, such as Figure 15 As shown, the upper end of the air duct 430 is connected to the dust outlet 211 of the sewage tank 210, and the lower end of the air duct 430 is connected to the dust collection module 130. A first switching valve 510 is provided at the lower end of the air duct 430, and an air inlet 511 is provided on the first switching valve 510. The first switching valve 510 can switch between connecting the sewage tank 210 and the air inlet 511, and between connecting the air duct 430 and the dust collection module 130.

[0078] When it is necessary to discharge the garbage in the sewage tank 210 to the dust collection module 130, the first switching valve 510 closes the air inlet 511 and connects the air duct 430 to the dust collection module 130. At this time, the garbage in the sewage tank 210 can enter the air duct 430 from the dust discharge port 211 and be discharged into the dust collection module 130 along the air duct 430.

[0079] This configuration prevents waste from flowing along the air duct 430 to the air inlet 511, and prevents waste from being discharged from the air inlet 511, thus avoiding pollution of the environment inside the base station 10. At the same time, it also prevents waste from blocking the air inlet 511 and affecting the air from entering the sewage tank 210 from the air inlet 511.

[0080] In other embodiments, the first switching valve 510 controls the opening and closing of the air duct 430 and the dust collection module 130, and the air inlet 511 is always connected to the sewage tank 210 through the air guide channel 420 to ensure the airflow in the sewage tank 210.

[0081] The air inlet 511 is equipped with a filter device, which can filter the air entering the air guide channel 420 from the air inlet 511 and prevent the garbage in the air guide channel 420 from being discharged from the air inlet 511.

[0082] like Figure 6 As shown, in this embodiment, the dust discharge port 211 is located above the sewage tank 210, and the upper end of the air duct 430 is connected to the dust discharge port 211 of the sewage tank 210. When it is necessary to discharge the garbage in the sewage tank 210 to the dust collection module 130, the first switching valve 510 connects the air duct 430 and the dust collection module 130. At this time, the garbage in the sewage tank 210 can be driven upward into the dust discharge port 211 by negative pressure suction, etc., and then enter the air duct 430 from the dust discharge port 211, and is discharged downward along the air duct 430 to the dust collection module 130.

[0083] Steam outlet 212 is located above sewage tank 210. When sewage in sewage tank 210 needs to be treated to produce clean water, the first switching valve 510 closes the air pipe 430 and the dust collection module 130. At this time, the heating component heats the water in sewage tank 210 to generate steam. At this time, external air can enter the air pipe 430 from the air inlet 511 and flow upward into sewage tank 210 along the air pipe 430, so as to drive the steam in sewage tank 210 to flow upward to steam outlet 212, so that the steam can flow out from steam outlet 212.

[0084] In some embodiments of the present invention, the water treatment module 20 further includes a transfer sewage tank 230, which is connected to a sewage inlet and a sewage tank 210 respectively. Sewage collected by the sweeping robot 90 can flow into the transfer sewage tank 230 through the sewage inlet, and sewage in the transfer sewage tank 230 can flow into the sewage tank 210 through a drainage pipe.

[0085] By setting up a transfer sewage tank 230, the sewage collection capacity of the base station 10 can be improved, enabling the base station 10 to store more sewage, which is convenient for subsequent extraction of clean water from the sewage through the heating component and cooling module 320.

[0086] The drainage pipe between the transfer sewage tank 230 and the sewage tank 210 is connected in series with a control valve 540 for opening or closing it, so as to control whether the water in the transfer sewage tank 230 can flow into the sewage tank 210 through the drainage pipe. When the control valve 540 opens the drainage pipe, the water in the transfer sewage tank 230 can enter the sewage tank 210 through the drainage pipe. When the control valve 540 closes the drainage pipe, it can seal the sewage tank 210 to a certain extent, so that the water vapor formed in the sewage tank 210 can flow from the steam outlet 212 to the cooling module 320. At this time, the water in the transfer sewage tank 230 cannot enter the sewage tank 210 along the drainage pipe.

[0087] Specifically, when the heating element heats the sewage in the sewage tank 210, the pressure inside the sewage tank 210 is high. At this time, the drain pipe needs to be closed through the control valve 540 to prevent the water in the sewage tank 210 from flowing back into the transfer sewage tank 230 along the drain pipe. When the heating element stops heating the water in the sewage tank 210 and the pressure inside the sewage tank 210 returns to normal, the drain pipe can be opened through the control valve 540, at which point the water in the transfer sewage tank 230 can flow back into the sewage tank 210 along the drain pipe.

[0088] In other words, when the heating component heats the water in the wastewater tank 210, water from the transfer wastewater tank 230 should be prevented from entering the wastewater tank 210. By closing the drain pipe through the control valve 540, water from the transfer wastewater tank 230 is prevented from entering the wastewater tank 210, so that the wastewater collected by the sweeping robot 90 can be discharged into the transfer wastewater tank 230 from the wastewater inlet and the heating component can heat the water in the wastewater tank 210 at the same time.

[0089] In some optional embodiments of the present invention, the transfer sewage tank 230 is provided with a water outlet 231, an air inlet 232 and a sealing cavity 233. The sewage collected by the sweeping robot 90 can flow into the transfer sewage tank 230 through the sewage inlet. This part of the sewage can be stored in the sealing cavity 233. The sealing cavity 233 is connected to the water outlet 231. The sewage in the sealing cavity 233 can flow into the sewage tank 210 through the water outlet 231.

[0090] The sealed cavity 233 is also connected to the air inlet 232. The transfer sewage tank 230 is equipped with a pressure relief pipe 234, which is connected to the air inlet 232. The air outlet 2341 of the pressure relief pipe 234 extends to the upper part of the transfer sewage tank 230. The pressure relief pipe 234 is used to balance the pressure in the sealed cavity 233 so as to ensure that the sewage in the sealed cavity 233 can flow smoothly into the sewage tank 210 and ensure that the sewage collected by the sweeping robot 90 can flow smoothly into the transfer sewage tank 230 through the sewage inlet.

[0091] The control valve 540 is connected to the sealing cavity 233 to control whether the water in the sealing cavity 233 can flow into the sewage tank 210 through the water outlet 231. When the control valve 540 opens the sealing cavity 233, the water in the sealing cavity 233 can enter the sewage tank 210 through the water outlet 231. When the control valve 540 closes the sealing cavity 233, it can ensure that the sealing cavity 233 is sealed to a certain extent.

[0092] like Figure 10 As shown, the sealing cavity 233 is located to the left of the control valve 540, which can move in the left and right directions. The water outlet 231 is located below the control valve 540. When the control valve 540 moves to the right, it connects the sealing cavity 233 and the water outlet 231. At this time, the water in the sealing cavity 233 can flow into the sewage tank 210 through the water outlet 231 to replenish the water in the sewage tank 210.

[0093] When there is no need to replenish the sewage tank 210, the control valve 540 can move to the left to disconnect the sealing cavity 233 and the water outlet 231. At this time, the water in the sealing cavity 233 will not flow out from the water outlet 231. It should be understood that the above directional limitation is only for the convenience of describing the attached drawings and does not limit the actual setting position and direction of the base station 10.

[0094] In some embodiments, the outlet 231 is connected to the sewage tank 210 via a drainage pipe, and the control valve 540 can control the connection or disconnection between the sealing cavity 233 and the outlet 231. Specifically, when the control valve 540 controls the connection between the sealing cavity 233 and the outlet 231, the sewage in the transfer sewage tank 230 can enter the drainage pipe from the outlet 231 and flow into the sewage tank 210 along the drainage pipe. When the sewage in the sewage treatment tank flows into the sewage tank 210 from the outlet 231 along the drainage pipe, outside air can enter the sealing cavity 233 from the air outlet 2341 of the pressure relief port along the pressure relief pipe 234 and the air inlet 232 to balance the pressure in the sealing cavity 233, so that the sewage in the sealing cavity 233 can smoothly flow into the sewage tank 210 from the outlet 231 along the drainage pipe.

[0095] In some embodiments of the present invention, the water treatment module 20 further includes a compressor 710, a condenser 730, and a throttling element 740. The compressor 710, condenser 730, throttling element 740, and cooling module 320 are connected to form a refrigerant flow loop. When the refrigerant circulates between the compressor 710, condenser 730, throttling element 740, and evaporator 720, it can release heat at the condenser 730 to heat the air around the condenser 730 and absorb heat at the evaporator 720 to cool the air near the evaporator.

[0096] Specifically, the compressor 710 can drive the refrigerant to circulate between the compressor 710, condenser 730, throttling element 740, evaporator 720, and compressor 710. The compressor 710 can also compress the refrigerant to compress the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, and drive the high-temperature, high-pressure gaseous refrigerant to flow to the condenser 730. The high-temperature, high-pressure gaseous refrigerant releases heat at the condenser 730 and becomes a medium-temperature, high-pressure liquid refrigerant. When the high-temperature, high-pressure gaseous refrigerant releases heat at the condenser 730, it can heat the air around the condenser 730 to form hot air.

[0097] Driven by the compressor 710, the medium-temperature, high-pressure liquid refrigerant flows to the throttling element 740. After being processed by the throttling element 740, it becomes a low-temperature, low-pressure liquid refrigerant. The low-temperature, low-pressure liquid refrigerant flows to the evaporator 720. After absorbing heat at the evaporator 720, it becomes a low-temperature, low-pressure gaseous refrigerant. When the low-temperature, low-pressure gaseous refrigerant absorbs heat at the evaporator 720, it can cool the air near the evaporator 720.

[0098] Under the continued drive of compressor 710, low-temperature and low-pressure gaseous refrigerant can flow to compressor 710, so as to realize the circulation of refrigerant between compressor 710, condenser 730, throttling element 740, evaporator 720 and compressor 710.

[0099] In some embodiments, the evaporator 720 defines a cooling module 320. When the refrigerant absorbs heat at the evaporator 720, the evaporator 720 can absorb heat from the air so that the air can release heat and liquefy into condensate. The evaporator 720 can also cool the steam discharged from the steam outlet 212 of the wastewater tank 210 so that the steam can release heat and liquefy into condensate to obtain clean water.

[0100] In some optional embodiments of the present invention, the mating part defines a receiving space 110 for accommodating the sweeping robot 90. The base station 10 also includes a first fan 810 and an air guide duct. The condenser 730 is located in the air guide duct or at the air inlet end of the air guide duct. The first fan 810 is used to guide the air in the air guide duct to the receiving space 110 to drive the hot air near the condenser 730 into the receiving space 110, and use the hot space to dry the sweeping robot 90 in the receiving space 110.

[0101] Specifically, when the refrigerant flows within the condenser 730, it releases heat to heat the air surrounding the condenser 730, generating hot air around it. The condenser 730 is positioned within the air duct or at the air inlet of the air duct so that the first fan 810 can fully drive the hot air around the condenser 730, allowing it to flow into the air duct and then into the receiving space 110. This allows the hot air to dry the robotic vacuum cleaner 90 within the receiving space 110, facilitating cleaning, maintenance, or other operations on the robot vacuum cleaner 90's base.

[0102] like Figure 2 As shown, in some embodiments, the accommodating space 110 has two sewage inlets, two dust inlets 112 and two clean water outlets, and the two sewage inlets, two dust inlets 112 and two clean water outlets are all located on both sides of the accommodating space 110.

[0103] In some specific embodiments of the present invention, such as Figure 4 As shown, the condenser 730 is located below the evaporator 720 to position the condenser 730 and the evaporator 720 in a suitable location, while also shortening the path of the refrigerant flow between the condenser 730 and the evaporator 720, thus reducing the loss of refrigerant energy.

[0104] The first fan 810 is located on one side of the condenser 730 to blow air toward the condenser 730, so that the hot air around the condenser 730 can flow along the air duct into the housing space 110, so that the hot air can dry the sweeping robot 90 in the housing space 110, so as to facilitate the subsequent cleaning, maintenance or other operations on the bottom plate of the sweeping robot 90.

[0105] In some embodiments of the present invention, the water treatment module 20 is provided with an air inlet 421 for introducing external air into the base station 10. The base station 10 includes a sewage treatment mode and an air-water treatment mode to produce clean water in different ways, which facilitates improving the efficiency of the base station 10 in producing clean water.

[0106] Specifically, in wastewater treatment mode, water treatment module 20 is used to treat wastewater to obtain clean water. In air-water treatment mode, water treatment module 20 is used to dehumidify the introduced outside air to obtain clean water.

[0107] In some optional embodiments of the present invention, the water treatment module 20 includes a sewage tank 210, a heating component, a cooling module 320, a gas guide channel 420, and a second switching valve 520. The sewage tank 210 is provided with a steam outlet 212, the gas guide channel 420 is connected to the steam outlet 212, an air inlet 421 is provided in the gas guide channel 420, and the second switching valve 520 is provided in the gas guide channel 420 to control the connection or closure of the gas guide channel 420 and the steam outlet 212. The cooling module 320 is used to cool the gas discharged from the gas guide channel 420 to obtain clean water. By controlling the connection or closure of the gas guide channel 420 and the steam outlet 212 through the second switching valve 520, the base station 10 can be controlled to switch between sewage treatment mode and air-water treatment mode.

[0108] Specifically, when the second switching valve 520 controls the air guide channel 420 to connect with the steam outlet 212, the air guide channel 420 and the air inlet 421 are closed, and the base station 10 is in the sewage treatment mode. At this time, the heating component can heat the sewage. The water in the sewage tank 210 absorbs heat and evaporates into steam. The steam can enter the air guide channel 420 from the steam outlet 212 and flow along the air guide channel 420 to the cooling module 320. The cooling module 320 can cool the gas discharged from the air guide channel 420 to obtain clean water.

[0109] When the second switching valve 520 controls the air guide channel 420 to close the steam outlet 212, the air guide channel 420 is connected to the air inlet 421. At this time, the base station 10 is in the air-water treatment mode. Air from the external environment of the base station 10 can enter the air guide channel 420 from the air inlet 421 and flow along the air guide channel 420 to the cooling module 320. The cooling module 320 dehumidifies this part of the air to produce clean water.

[0110] In addition, by dehumidifying the environment where the base station 10 is located, the environment where the base station 10 is located can be made drier, avoiding the shortening of the service life of electrical appliances or the occurrence of safety hazards caused by humid air.

[0111] like Figure 4 As shown, in this embodiment, the air guide channel 420 is also provided with a steam inlet 422, and the steam outlet 212 is connected to the air guide channel 420 through the steam inlet 422. The steam inlet 422 is located on one side of the air guide channel 420 and extends in the vertical direction. The air inlet 421 is located above the air guide channel 420 and extends in the horizontal direction. The second switching valve 520 is rotatably located in the air guide channel 420 to switch between the air guide channel 420 and the air inlet 421 or the steam inlet 422.

[0112] When the second switching valve 520 rotates upward to the position of air inlet 421, the second switching valve 520 extends horizontally to close air inlet 421 and open steam inlet 422. At this time, the base station 10 is in wastewater treatment mode. When the second switching valve 520 rotates downward to the position of steam inlet 422, the second switching valve 520 extends vertically to close steam inlet 422 and open air inlet 421. At this time, the base station 10 is in air-water treatment mode.

[0113] When it is necessary to discharge the waste in the sewage tank 210 to the dust collection module 130, the second switching valve 520 simultaneously opens the steam inlet 422 and the air inlet 421. For example, at this time, the second switching valve 520 is rotated to the 45° position to simultaneously open the steam inlet 422 and the air inlet 421.

[0114] Specifically, the waste in the sewage tank 210 is driven upward into the dust discharge port 211 by negative pressure suction. From the dust discharge port 211, it is discharged into the dust collection module 130 along the air pipe 430. When the air in the sewage tank 210 is being suctioned, the air in the external environment can enter the air guide channel 420 from the air inlet 421 and enter the sewage tank 210 from the steam outlet 212 along the air guide channel 420 to ensure the air flow in the sewage tank 210, so that the waste in the sewage tank 210 can move upward smoothly to the dust discharge port 211.

[0115] Meanwhile, when the negative pressure suction of the garbage in the sewage tank 210 is stopped, air from the external environment can enter the air guide channel 420 through the air inlet 421, flow from the steam outlet 212 along the air guide channel 420 into the steam outlet 212, and then flow into the sewage tank 210 to balance the air pressure in the sewage tank 210.

[0116] In addition, air from outside the base station 10 can also enter the sewage tank 210 through the air inlet 511 and the air duct 430 to balance the air pressure inside the sewage tank 210.

[0117] In some embodiments of the present invention, the clean water collection module 600 includes a transfer clean water tank 630 and a clean water tank 610. The transfer clean water tank 630 cooperates with the water treatment module 20 to collect clean water. The clean water tank 610 is connected to the transfer clean water tank 630 and the clean water outlet. The clean water tank 610 is used to receive the clean water discharged from the transfer clean water tank 630. The water in the transfer clean water tank 630 can flow into the clean water tank 610 to replenish the clean water in the clean water tank 610. The water in the clean water tank 610 can flow from the clean water outlet to the mating part so as to use the clean water in the clean water tank 610 to clean the sweeping robot 90.

[0118] Specifically, the clean water produced by the water treatment module 20 can be discharged into the intermediate clean water tank 630, and the water in the intermediate clean water tank 630 can then flow into the clean water tank 610 to replenish the clean water in the clean water tank 610. The water in the clean water tank 610 can flow from the clean water outlet to the mating part so as to use the clean water in the clean water tank 610 to clean the sweeping robot 90.

[0119] The inclusion of a transfer water tank 630 and a water tank 610 enhances the water storage capacity of the base station 10, enabling it to store more water and thus thoroughly clean the bottom plate of the sweeping robot 90.

[0120] In some optional embodiments of the present invention, at least a portion of the bottle body of the transfer water tank 630 is a visible structural component to observe the water level inside the transfer water tank 630, so as to facilitate the user to observe the water level inside the transfer water tank 630.

[0121] In some embodiments, such as Figure 14 As shown, the intermediate clean water tank 630 includes a first tank 631 and a second tank 632. The first tank 631 and the second tank 632 are connected. The first tank 631 is cylindrical. The water inlet 6311 of the first tank 631 is connected to the water treatment module 20. The drain outlet 6321 of the second tank 632 is connected to the clean water tank 610. The tank wall of the first tank 631 is made of a transparent material, such as glass, transparent plastic or other visible material, so as to facilitate the user to observe the water level in the first tank 631, and thus facilitate the user to observe the water level in the intermediate clean water tank 630.

[0122] Specifically, the clean water produced by the water treatment module 20 enters the intermediate clean water tank 630 from the water inlet 6311 of the first tank 631. The clean water in the intermediate clean water tank 630 flows into the clean water tank 610 from the drain outlet 6321 of the second tank 632 to replenish the clean water in the clean water tank 610, so that the clean water in the clean water tank 610 can be used to clean the bottom plate of the sweeping robot 90 later.

On the one hand, it can prevent sewage or garbage from polluting the sweeping robot 90 again, so as to clean the bottom plate of the sweeping robot 90. On the other hand, it facilitates the extraction of clean water from the sewage in the future, so as to make full use of water.
