[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] After long-term research, the inventors have found that intelligent cleaning devices often have a dust suction function, but the wind force of current intelligent cleaning devices when dusting is low, and the dust suction effect is poor, resulting in incomplete cleaning. The stronger the suction force of the fan module, the greater the power, and the more heat is generated. The heat is not conducive to the normal operation of various components inside the fan module, resulting in the fan module maintaining a strong suction state for a short time, affecting the dust suction effect. In order to solve this technical problem, the present application provides the following embodiments.

[0018] like Figure 1 As shown, the cleaning device 1 described in the embodiment of the cleaning device of the present application is a sweeping and mopping robot. The cleaning device 1 can perform cleaning tasks according to the mode set by the user or based on a specific scene, such as a carpet. When the cleaning device 1 is sweeping the floor, the cleaning device 1 can absorb various garbage objects from the outside, such as dust particles, paper scraps, hair, etc. When the cleaning device 1 is mopping the floor, the cleaning device 1 can wet the work surface to remove dirt on the work surface. The following is an exemplary structure of the cleaning device 1.

[0019] The cleaning device 1 may include a device body 100 and a dust box (not shown). The dust box is detachably connected to the device body 100. Specifically, the dust box may be installed on the device body 100 by insertion, assembly, combination, etc. The function of the dust box is to collect various garbage objects absorbed by the cleaning device 1 when performing external cleaning work, such as dust particles, paper scraps, hair, etc. A dust suction port may be provided at the bottom of the device body 100 facing the working surface (such as the ground) of the cleaning device 1. The dust suction port is connected to the interior of the dust box, and the garbage on the ground enters the dust box through the dust suction port.

[0020] The bottom of the device body 100 may be provided with a walking assembly and a cleaning assembly, and the walking assembly can make the cleaning device 1 movable. The walking assembly includes a driving wheel and a universal wheel, and the device body 100 is driven by the driving wheel to move. The cleaning assembly may include a roller brush, which may be provided at the bottom of the main shell, and is used to provide a cleaning function when the cleaning device 1 is working, and clean the working surface of the cleaning device 1.

[0021] like Figures 2 to 4As shown, the cleaning device 1 also includes a fan module 400. The fan module 400 can be used to suck dust, debris and other garbage objects on the working surface into the dust box. The cleaning component and the fan module 400 can cooperate with each other and work together. For example, a roller brush can be set at the dust suction port, so that the garbage or dust swept out during the rotation of the roller brush can be sucked into the dust box by the fan module 400.

[0022] The cleaning device 1 described in the embodiment of the cleaning device of the present application may also include a cleaning mechanism 130 and a water tank 300. The cleaning mechanism 130 is disposed on the device body 100 and is used to clean the area to be cleaned in a wet state. The water tank 300 is used to contain a cleaning liquid, and the cleaning liquid is used to be directed to the cleaning mechanism 130 to wet the cleaning mechanism 130. The cleaning liquid can be clean water or a mixture of clean water and a detergent.

[0023] Alternatively, if Figure 5 As shown, the cleaning mechanism 130 includes a connection seat 133, a mop 134 and a connection shaft 136, and the connection shaft 136 and the mop 134 are connected through the connection seat 133. The connection seat 133 is provided with an avoidance hole 135, and the connection seat 133 avoids the cleaning liquid flowing out of the water tank 300 through the avoidance hole 135, so that the cleaning liquid flows onto the mop 134 to wet the mop 134. During the cleaning process, the mop 134 can be wetted by the cleaning liquid to improve the cleaning effect of the mop 134.

[0024] Specifically, the mop 134 is connected to one side of the connection seat 133, and one end of the connection shaft 136 is detachably connected to the side of the connection seat 133 away from the mop 134. The cleaning mechanism 130 can contact the area to be cleaned through the mop 134. During the cleaning process, the connection shaft 136 is driven to drive the connection seat 133 to rotate, and the connection seat 133 synchronously drives the mop 134 to rotate. The mop 134 cleans the area to be cleaned by rotating relative to the area to be cleaned. In this embodiment, the rotation axis of the mop 134 is perpendicular to the area to be cleaned. In some other embodiments, the mop can also be in the form of a roller, and the rotation axis of the roller is parallel to the area to be cleaned. Alternatively, a fan-shaped mop can also be used, and the fan-shaped mop wipes the area to be cleaned by reciprocating translation rather than rotation.

[0025] Optionally, the material of the mop 134 may include a soft material that can absorb water.

[0026] The structure of the cleaning device 1 described above is merely an example and is not limited to the above example structure.

[0027] like Figures 1 to 4As shown, the cleaning device 1 described in the embodiment of the cleaning device of the present application includes a device body 100, a cleaning mechanism 130, a water tank 300, a fan module 400 and a water circulation component 500. The cleaning mechanism 130 is arranged on the device body 100, and is used to clean the area to be cleaned. The water tank 300 is used to contain a cleaning liquid, and the cleaning liquid is used to be directed to the cleaning mechanism 130 to wet the cleaning mechanism 130. The fan module 400 is arranged on the device body 100, and is used to provide suction for the cleaning device 1 to absorb garbage. The water circulation component 500 is arranged in contact with the fan module 400 and is connected to the water tank 300. The cleaning liquid in the water tank 300 is also used to flow into the water circulation component 500 and flow back from the water circulation component 500 to the water tank 300. Among them, the cleaning mechanism 130 can clean the area to be cleaned in a wet state. The cleaning liquid in the water tank 300 is used to flow to the water circulation component 500 to cool the fan module 400. After the cleaning liquid flows back to the water tank 300 through the water circulation component 500, the cleaning liquid directed to the cleaning mechanism 130 can be heated.

[0028] The fan module 400 may generate heat when working, and heat accumulation is not conducive to the continuous operation of the fan module 400. Specifically, the fan module 400 often needs to work in a state of strong suction, for example, the fan module 400 needs strong suction when sucking dust and garbage in the carpet. The stronger the suction of the fan module 400, the greater the power, and the more heat is generated. The heat is not conducive to the normal operation of various devices (such as circuit boards) inside the fan module 400, resulting in a shorter time for the fan module 400 to maintain a strong suction state, affecting the dust collection effect.

[0029] The water circulation component 500 has a heat conduction function. The water circulation component 500 is used to guide the cleaning liquid with a lower temperature in the water tank 300, thereby increasing the contact area between the water circulation component 500 and the cleaning liquid, reducing the distance between the fan module 400 and the cleaning liquid, and facilitating the transfer of the heat generated by the fan module 400 to the cleaning liquid. The heat generated by the fan module 400 can be absorbed by the cleaning liquid in the water circulation component 500 through the water circulation component 500, thereby promoting the heat dissipation of the fan module 400, which is conducive to the fan module 400 maintaining a strong suction state for a long time, and improving the heat dissipation and dust collection effect.

[0030] By providing the water circulation assembly 500, the cleaning liquid in the water tank 300 can flow out of the water tank 300 and flow close to the fan module 400, and then flow back to the water tank 300. The cleaning liquid can be heated by the fan module 400. After the cleaning liquid flows back, the temperature of the cleaning liquid in the water tank 300 increases. The cleaning liquid with a higher temperature is directed to the cleaning mechanism 130 to help dissolve the stains in the area to be cleaned, thereby improving the cleaning effect of the cleaning mechanism 130 on the area to be cleaned.

[0031] Furthermore, in this embodiment, the water tank 300 originally used for mopping the floor of the cleaning device 1 is utilized, and no other structures are added except the water circulation component 500. The water circulation component 500 occupies a small space and thus does not affect the volume of the cleaning device 1.

[0032] In some embodiments, the cleaning liquid flows from the water tank 300 into the water circulation assembly 500, stays there for a while, and then flows back to the water tank 300. In another embodiment, the cleaning liquid flows from the water tank 300 into the water circulation assembly 500 and flows back to the water tank 300 from the water circulation assembly 500 simultaneously.

[0033] Alternatively, if Figures 2 to 4 As shown, the water tank 300 is provided with a receiving space 301 and a first liquid outlet 302 and a first liquid inlet 303 communicating with the receiving space 301, and the receiving space 301 is used to receive the cleaning liquid. The water circulation component 500 is provided with a flow passage 501 and a second liquid outlet 502 and a second liquid inlet 503 communicating with the flow passage 501, the second liquid outlet 502 is communicated with the first liquid inlet 303, and the second liquid inlet 503 is communicated with the first liquid outlet 302.

[0034] The cleaning liquid with a lower temperature in the accommodation space 301 can flow out from the first liquid outlet 302 and flow into the flow channel 501 through the second liquid inlet 503. The cleaning liquid in the flow channel 501 absorbs the heat generated by the fan module when passing through the fan module and the temperature increases. The cleaning liquid with a higher temperature in the flow channel 501 can flow out from the second liquid outlet 502 and flow into the accommodation space 301 through the first liquid inlet 303. In this way, the circulation of the cleaning liquid between the water tank 300 and the water circulation component 500 can be easily realized.

[0035] Alternatively, if Figures 2 to 4 As shown, the water circulation component 500 is provided with a first water pump 510. The first water pump 510 is used to transport the cleaning liquid from the second liquid outlet 502 to the first liquid inlet 303, and is also used to transport the cleaning liquid from the first liquid outlet 302 to the second liquid inlet 503.

[0036] The first water pump 510 can provide power for the circulation of the cleaning liquid between the cleaning liquid tank 300 and the accommodating space 301. This is helpful to reduce the number of the first water pumps 510. For example, the first water pump 510 is a peristaltic pump.

[0037] In some embodiments, the first water pump 510 can also be used to deliver the cleaning liquid to the cleaning mechanism 130. For example, the water circulation component 500 can be provided with a Y-shaped pipeline, that is, the water circulation component 500 also has a mop liquid outlet that shares the second liquid inlet 503 with the second liquid outlet 502, and the first water pump 510 can also be used to deliver the cleaning liquid from the mop liquid outlet to the cleaning mechanism 130. In other embodiments, the cleaning device 1 is also provided with a second water pump 600, and the second water pump 600 is used to deliver the cleaning liquid to the cleaning mechanism 130. For example, the second water pump 600 is used to deliver the cleaning liquid from the mop liquid outlet to the cleaning mechanism 130. The cleaning liquid delivered to the cleaning mechanism 130 is the cleaning liquid that has been heated by flowing through the fan module.

[0038] Optionally, the water circulation component 500 can also be provided with two first water pumps 510, one of the two first water pumps 510 is used to transport the cleaning liquid from the second liquid outlet 502 to the first liquid inlet 303, and the other of the two first water pumps 510 is used to transport the cleaning liquid from the first liquid outlet 302 to the second liquid inlet 503.

[0039] In this way, the internal structural arrangement of the cleaning device 1 can be made highly flexible, thereby facilitating assembly. For example, the first water pump 510 is an air pump or a peristaltic pump. In some embodiments, when at least one first water pump 510 is provided on the cleaning device 1, the first water pump 510 is also used to transport the cleaning liquid flowing out through the first liquid outlet 302 to the cleaning mechanism 130. In other embodiments, the cleaning device 1 is also provided with a second water pump 600, and the second water pump 600 is used to transport the cleaning liquid flowing out through the first liquid outlet 302 to the cleaning mechanism 130.

[0040] Alternatively, if Figures 2 to 4 As shown, the first water pump 510 has a first water suction port 511 and a first water discharge port 512 . When the first water pump 510 is working, the cleaning liquid enters the first water pump 510 from the first water suction port 511 and then flows out from the first water discharge port 512 .

[0041] Alternatively, if Figures 1 to 3 As shown, the water tank 300 is further provided with a third liquid outlet 304 communicating with the accommodating space 301 , and the third liquid outlet 304 is used to guide the cleaning liquid in the accommodating space 301 to the cleaning mechanism 130 .

[0042] The cleaning mechanism 130 is wetted with cleaning liquid and used for mopping the floor, while the fan module 400 is used for vacuuming. This arrangement allows the cleaning mechanism 130 and the fan module 400 to work independently, thereby reducing mutual interference between the two.

[0043] Alternatively, if Figure 2 and Figure 3As shown, the second water pump 600 has a second water inlet 601 and a second water outlet 602 . When the second water pump 600 is working, the cleaning liquid enters the second water pump 600 from the second water inlet 601 and then flows out from the second water outlet 602 .

[0044] Alternatively, if Figure 3 , Figure 5 and Figure 6 As shown, the water circulation component 500 includes a three-way valve 540, which has a water inlet 541, a first water outlet 542 and a second water outlet 543. The first liquid outlet 302 is connected to the water inlet 541, the first water outlet 542 is connected to the second liquid inlet 503, and the second water outlet 543 is used to guide the cleaning liquid flowing out through the first liquid outlet 302 to the cleaning mechanism 130.

[0045] With such configuration, the number of openings on the first water tank 300 can be reduced.

[0046] Optionally, the cleaning device 1 is further provided with a second water pump 600 , and the second water pump 600 is used to transport the cleaning liquid to the cleaning mechanism 130 .

[0047] In some embodiments, when the three-way valve 540 is not provided, the second water pump 600 is used to deliver the cleaning liquid from the third liquid outlet 304 to the cleaning mechanism 130. In other embodiments, when the three-way valve 540 is provided, the second water pump 600 is used to deliver the cleaning liquid from the second water outlet 543 to the cleaning mechanism 130.

[0048] Optionally, the water circulation component 500 is provided with a first water pump 510. The first water pump 510 is used to transport the cleaning liquid from the first liquid outlet 302 to the second liquid inlet 503 and the cleaning mechanism 130 through the three-way valve 540, and is also used to transport the cleaning liquid from the second liquid outlet 502 to the first liquid inlet 303. Or the water circulation component 500 is provided with two first water pumps 510, one of the two first water pumps 510 is used to transport the cleaning liquid from the first liquid outlet 302 to the cleaning mechanism 130 through the three-way valve 540, and the other of the two first water pumps 510 is used to transport the cleaning liquid from the first liquid outlet 502 to the second liquid inlet 503 through the three-way valve 540, and then transport it to the first liquid inlet 303 through the second liquid outlet 502.

[0049] Specifically, when the three-way valve 540 is provided, the first water pump 510 is used to transport the cleaning liquid from the first liquid outlet 302 to the water inlet 541, which is conducive to reducing the number of first water pumps 510. For example, the first water pump 510 can transport the cleaning liquid from the first liquid outlet 302 to the water inlet 541, and then the cleaning liquid can flow from the water inlet 541 to the first water outlet 542 and the second water outlet 543 in the three-way valve 540.

[0050] In some embodiments, there are two first water pumps 510, and one of the first water pumps 510 is used to transport the cleaning liquid from the first liquid outlet 302 to the water inlet 541. For example, one of the two first water pumps 510 is used to transport the cleaning liquid from the first liquid outlet 302 to the second liquid inlet 503 and the cleaning mechanism 130 through the three-way valve 540, and the other of the two first water pumps 510 is used to transport the cleaning liquid from the second liquid outlet 502 to the first liquid inlet 303.

[0051] Furthermore, the three-way valve 540 is provided with a first valve 544 for blocking the first water outlet 542 and a second valve 545 for blocking the second water outlet 543 , so as to control the flow path of the cleaning liquid.

[0052] In some embodiments, Figure 7 As shown, the water tank 300 is provided with a first subspace 305 and a second subspace 306, and the first subspace 305 is connected to the second subspace 306 through a water circulation component 500, and the cleaning liquid can flow from the first subspace 305 through the water circulation component 500 into the second subspace 306, and then be directed to the cleaning mechanism 130. Further, the cleaning device 1 can also be provided with a second water pump 600, and the second water pump 600 is used to transport the cleaning liquid from the second subspace 306 to the cleaning mechanism 130. Under the suction action of the second water pump 600, the cleaning liquid flows from the first subspace 305 through the water circulation component 500 into the second subspace 306, and then flows to the cleaning mechanism 130.

[0053] In some embodiments, Figure 8 As shown, the water tank 300 is provided with a receiving space 301 for receiving the cleaning liquid and a first water exchange port 307 connected to the receiving space 301, and the water circulation component 500 is provided with a flow passage 501 and a second water exchange port 504 connected to the flow passage 501. The cleaning liquid in the receiving space 301 can enter the flow passage 501 from the first water exchange port 307 through the second water exchange port 504, and the cleaning liquid in the flow passage 501 can enter the receiving space 301 from the second water exchange port 504 through the first water exchange port 307, so as to realize the circulation of the cleaning liquid between the water tank 300 and the water circulation component 500. A first water pump 510 can be connected between the first water exchange port 307 and the second water exchange port 504. After the cleaning liquid in the receiving space 301 enters the flow passage 501 from the first water exchange port 307 through the second water exchange port 504, it can stay in the flow passage 501 for a period of time, and can be pumped back to the receiving space 301 after the temperature rises. In this way, the number of openings on the water tank 300 can be reduced, and the running time of the water pump can be reduced. For example, the first water pump 510 is a bidirectional pump, which can switch the direction of conveying the cleaning liquid so that the cleaning liquid flows back and forth between the water tank 300 and the water circulation component 500.

[0054] Alternatively, if Figure 3 As shown, the water tank 300 is provided with an air hole 309 connected to the outside to balance the air pressure in the water tank 300 and the atmospheric pressure so that the cleaning liquid can flow out of the water tank 300 smoothly. Furthermore, the air hole 309 is provided on the upper side of the water tank 300, so that the air hole 309 is not easy to leak.

[0055] Optionally, the water tank 300 and the first water pump 510 or the second water pump 600 may be connected via a hose.

[0056] Optionally, the first water pump 510 or the second water pump 600 may be installed on the outer wall of the water tank 300 .

[0057] Alternatively, if Figures 2 to 4 As shown, the water circulation component 500 includes a heat conducting pipe 550 , a flow passage 501 is opened in the heat conducting pipe 550 , and a second liquid outlet 502 and a second liquid inlet 503 are respectively arranged at two ends of the heat conducting pipe 550 .

[0058] The cleaning liquid can flow in the heat pipe 550 along the extension direction of the heat pipe 550, which is conducive to fully discharging the cleaning liquid with a higher temperature in the water circulation component 500 to the water tank 300, so that more cleaning liquid with a lower temperature in the water tank 300 can enter the heat pipe 550. By providing the heat pipe 550, it is convenient to install the water circulation component 500 on the device body 100, which is conducive to increasing the contact area between the water circulation component 500 and the fan module 400, and improving the heat transfer efficiency between the fan module 400 and the cleaning liquid.

[0059] Alternatively, if Figures 2 to 4 As shown, the heat pipe 550 is arranged to surround the outer circumference of the fan module 400 and surround it at least one circle.

[0060] Such a configuration is beneficial to increase the contact area between the heat pipe 550 and the fan module 400, improve the heat transfer efficiency between the fan module 400 and the cleaning liquid, and at the same time help reduce the space occupied by the water circulation component 500, making the layout compact.

[0061] Optionally, the heat pipe 550 is made of metal. The heat pipe 550 is made of metal and has good thermal conductivity, which can improve the heat transfer efficiency between the fan module 400 and the cleaning liquid.

[0062] Alternatively, if Figures 2 to 4As shown, the heat-conducting pipe 550 is a spiral metal pipe with high rigidity. During the assembly process, the spiral metal pipe can be sleeved on the fan module 400. Specifically, the fan module 400 can have a cylindrical heat-conducting outer shell 403, and the spiral metal pipe is sleeved on the heat-conducting outer shell 403. In some embodiments, the spiral metal pipe is connected to the heat-conducting outer shell 403 by a tight fit. In other embodiments, the spiral metal pipe is connected to the metal heat-conducting outer shell 403 by welding.

[0063] Optionally, the heat pipe 550 is made of a heat-conducting flexible polymer material, and during the assembly process, the heat pipe 550 can be spirally wound on the fan module 400. For example, during the assembly process, the heat pipe 550 can be spirally wound on the heat-conducting housing 403.

[0064] Optionally, the water circulation assembly 500 includes a heat conductor (not shown), which is filled between the heat pipe 550 and the fan module 400. Specifically, the heat conductive adhesive is configured to fill the gap between the heat pipe 550 and the heat conductive housing 403.

[0065] There is a gap between the heat pipe 550 and the fan module 400 after installation, or the contact area between the heat pipe 550 and the fan module 400 is small, which can lead to low heat transfer efficiency between the heat pipe 550 and the fan module 400. By filling a heat conductor between the heat pipe 550 and the fan module 400, the heat conductor can fully contact the heat pipe 550 and the fan module 400 respectively, which is conducive to improving the heat transfer efficiency between the heat pipe 550 and the fan module 400. For example, the heat conductor is a thermal conductive glue, a thermal conductive pad, etc. Among them, the thermal conductive glue also has the function of sticking the heat pipe 550 to the fan module 400.

[0066] In other embodiments, the heat conductor may also be a metal structure with heat conductivity, such as a silver sheet, a copper sheet, etc., which is arranged between the heat pipe 550 and the fan module 400 .

[0067] Alternatively, if Figures 2 to 4 As shown, the cleaning device 1 also includes a dust box (not shown) and a mounting bracket 700. The mounting bracket 700 is arranged on the device body 100 and is used to form a first mounting space 701 for accommodating the dust box and a second mounting space 702 for accommodating the fan module 400 and the heat pipe 550 together with the device body 100.

[0068] By providing the mounting bracket 700, it is convenient to install the dust box and the fan module 400, which is conducive to keeping the dust box and the fan module 400 relatively fixed, and reducing the possibility of air leakage. Further, the mounting bracket 700 is provided with a connection port 706 connecting the first mounting space 701 and the second mounting space 702, and the cleaning device 1 also includes a shock-absorbing pad 404. The fan module 400 has an air inlet 401 connected to the dust box through the connection port 706. The shock-absorbing pad 404 abuts between the outer periphery of the air inlet 401 of the fan module 400 and the outer periphery of the connection port 706, which can reduce the interference of the vibration of the fan module 400 on the mounting bracket 700 during operation. The shock-absorbing pad 404 can also play a sealing role, reducing the possibility of air leakage between the air inlet 401 of the fan module 400 and the connection port 706.

[0069] Alternatively, if Figures 2 to 4 As shown, the water tank 300 is located outside the second installation space 702 , and a avoidance opening 704 is provided on the installation bracket 700 , through which the heat pipe 550 is connected to the water tank 300 .

[0070] The heat conducting pipe 550 can be connected to the water tank 300 through a pipe (such as a hose), and the cleaning liquid in the water tank 300 can enter the heat conducting pipe 550 through the pipe. The avoidance opening 704 can allow the pipe to extend from outside the second installation space 702 to inside the second installation space 702.

[0071] Alternatively, if Figures 2 to 4 As shown, the cleaning device 1 further includes an exhaust bracket 705 connected to the mounting bracket 700 by a buckle, and the exhaust bracket 705 can be used to form a second installation space 702 and an exhaust channel 703 connected to the device body 100 and the mounting bracket 700, and the exhaust channel 703 is connected to the outside. The fan module 400 has an air outlet 402 connected to the exhaust channel 703, and the air outlet 402 can be opened on the heat-conducting housing 403. The main part of the heat-conducting pipe 550 is arranged to avoid the air outlet 402, so as to facilitate the exhaust of the fan module 400.

[0072] Alternatively, if Figures 2 to 4 As shown, the exhaust bracket 705 may also be provided with a avoidance opening 704 , and both ends of the heat pipe 550 are connected to the water tank 300 through the avoidance opening 704 of the exhaust bracket 705 and the avoidance opening 704 of the mounting bracket 700 , respectively.

[0074] When the water tank 300 is short of water, the cleaning device 1 can be connected to the base station 2 to obtain cleaning liquid with a lower temperature through the base station 2. When the cleaning liquid in the water tank 300 has an insufficient cooling effect on the fan module 400 due to the increase in temperature, the cleaning device 1 can discharge the cleaning liquid with a higher temperature in the water tank 300 to the base station 2, and obtain the cleaning liquid with a lower temperature through the base station 2, so that the cleaning liquid in the water tank 300 maintains a lower temperature.

[0075] Alternatively, if Figure 2 and Fig. 9 As shown, a water inlet 308 is provided on the water tank 300 , and the base station 2 transports cleaning liquid into the water tank 300 through the water inlet 308 .

[0076] In some embodiments, the base station 2 may have a cleaning liquid tank 21, which can be used to supply water to the water tank 300. In other embodiments, the base station 2 is connected to an external faucet, and the external faucet can be used to supply water to the water tank 300 through the base station 2.

[0077] Alternatively, if Figure 3 As shown, the base station 2 may include a base station body 210 and a base 220. The base station body 210 and the base 220 are connected. For example, the base station body 210 may be disposed on one side of the base 220, or the base station body 210 may be disposed above the base 220. The base 220 may be used to carry the cleaning device 1. For example, the cleaning device 1 may walk to the base 220 and stay on the base 220. The base station body 210 may suck garbage objects in the cleaning device 1 carried on the base 220.

[0078] Optionally, the base station 2 may have a cleaning liquid tank 21, a dust box 23, a sewage tank 24, a second fan 25, a pumping mechanism 26, a liquid supply mechanism 27, and an air supply mechanism 28. Specifically, the base station body 210 has a dust box 23, a sewage tank 24, a second fan 25, a pumping mechanism 26, a liquid supply mechanism 27, and an air supply mechanism 28. Further, the base station body 210 may also have a first shell 29. The cleaning liquid tank 21, the dust box 23, the sewage tank 24, and the air supply mechanism 28 may be arranged in the first shell 29, and are arranged at intervals from each other. The second fan 25 is used to suck the garbage objects in the cleaning device 1 into the dust box 23. The dust box 23 is used to retain the garbage objects sucked from the cleaning device 1. The cleaning liquid tank 21 can supply water to the cleaning device 1 for consumption and utilization by the cleaning device 1. The sewage tank 24 is used to contain the sewage or waste liquid generated after cleaning the cleaning device 1. The cleaning liquid tank 21 can also supply water to clean the cleaning device 1. The pumping mechanism 26 is used to pump the sewage generated after cleaning the cleaning device 1 into the sewage tank 24. The liquid supply mechanism 27 is used to deliver or pump the cleaning liquid to the cleaning device 1. The gas supply mechanism 28 is used to provide drying gas, so that the corresponding area of ​​the cleaning device 1 can be dried after cleaning.

[0079] In some embodiments, the base station 2 is not provided with a sewage tank 24, and the pumping mechanism 26 can be connected to a floor drain in the scene to be cleaned to automatically pump the sewage to the floor drain.

[0080] To summarize, the present embodiment can realize the water circulation component 500, which is beneficial to transfer the heat generated by the fan module 400 to the cleaning liquid. The heat generated by the fan module 400 can be absorbed by the cleaning liquid in the water circulation component 500 through the water circulation component 500, thereby promoting the temperature of the fan module 400 to decrease, which is beneficial for the fan module 400 to maintain a strong suction state for a long time, thereby improving the heat dissipation and dust collection effects. The cleaning liquid in the water circulation component 500 can be heated by the fan module 400. After the cleaning liquid flows back, the water temperature in the water tank 300 increases, and the cleaning liquid with a higher temperature is directed to the cleaning mechanism 130, which helps to dissolve the stains in the area to be cleaned, thereby improving the cleaning effect of the cleaning mechanism 130 on the area to be cleaned.
