[0003] Existing floor scrubbing systems generally include a base station and cleaning equipment. When filling the clean water tank on the cleaning equipment with water or performing self-cleaning, there is a risk of liquid overflowing onto the base station bearing part and damaging the electronic components in the base station, thereby reducing the safety and working stability of the base station.

[0004] An embodiment of the present application provides a base station and a cleaning system. The base station is provided with a reflux pipeline to allow liquid overflowing onto the base station to flow back into a water tank, thereby preventing electronic components or circuits on the base station from being soaked in water, thereby improving the working stability and safety of the base station, and improving the working stability and practicality of the cleaning system.

[0005] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0006] The first aspect of the embodiments of the present application provides a base station, the base station comprising: a base, the base having a bearing portion, the bearing portion being used to bear a floor brush assembly of a cleaning device; the water tank being used to supply liquid to a target container. A return line, the first end of the return line extending to the bearing portion, the second end of the return line extending into the water tank. In the process of the water tank supplying liquid to the target container, a negative pressure is formed in the water tank, and the negative pressure can act on the return line, so that the liquid on the bearing portion flows into the water tank through the return line.

[0007] The base station provided by the embodiment of the present application is provided with a floor brush assembly on a bearing part on a base, a water tank is provided on the base, one end of the return pipe extends to the bearing part, and the other end of the return pipe extends into the water tank, and in the process of the water tank supplying liquid to the target container, a negative pressure can be formed in the water tank, so that when liquid appears on the bearing part, the liquid enters the return pipe through the first end of the return pipe under the action of the negative pressure in the water tank, and flows into the water tank through the second end, thereby preventing the electronic devices or circuits on the base station from being damaged by the liquid on the bearing part, thereby improving the working stability and safety of the base station. Furthermore, the return pipe can also serve as an air passage in the process of the water tank supplying liquid to the target container, so as to facilitate air intake through the return pipe during the process of the water tank supplying liquid, thereby smoothly completing the liquid supply. In the present application, the return pipe can realize the reflux of the liquid on the bearing part on the basis of realizing the liquid supply of the water tank, so that the return pipe can realize multiple functions in different situations, with high flexibility, simple structure and low cost.

[0008] Furthermore, by returning the liquid on the carrying part to the water storage tank through the reflux pipe, the liquid on the carrying part can be reused, thereby reducing the waste of water resources, reducing the use cost of the cleaning system, and improving the practicality of the base station and the cleaning system.

[0009] Based on the above technical solution, the present application can also be improved as follows.

[0010] In a possible implementation, along the height direction of the water storage tank, the position to which the second end of the return pipe extends is higher than the position where the highest liquid level in the water storage tank is located.

[0011] By making the second end of the return pipe extend to a position higher than the position of the highest liquid level in the water tank, the second end can be prevented from being below the liquid level in the water tank, and in the process of adding liquid to the water tank, the liquid in the water tank can be prevented from entering the return pipe from the second end, thereby causing other adverse effects. At the same time, by making the second end of the return pipe extend to a position higher than the position of the highest liquid level in the water tank, the liquid in the water tank can be prevented from entering the return pipe, so that the inside of the water tank is connected to the outside through the return pipe, and the return pipe is used as a gas passage in the process of the water tank supplying liquid to the target container, so that air can be taken in through the return pipe during the process of the water tank supplying liquid, thereby successfully completing the liquid supply.

[0012] In a possible implementation manner, the bearing portion has a low-position area along the height direction of the base, and the first end of the return pipeline extends to the low-position area.

[0013] By providing a low-position area along the height direction of the base on the load-bearing part, water on the load-bearing part can be gathered toward the low-position area, and the first end of the return pipe can be extended to the low-position area, so that when liquid appears on the load-bearing part, the water gathered in the low-position area on the load-bearing part can be easily returned to the water storage tank through the return pipe, which is beneficial to improving the cleaning efficiency of the water on the load-bearing part and reducing processing time and cost.

[0014] In a possible implementation, the bearing portion includes a bearing bottom surface and a side surface surrounding the outer periphery of the bearing bottom surface; an opening is formed on one of the bearing bottom surface and the side surface, and the first end of the return line is connected to the opening.

[0015] By configuring the bearing part to include a bearing bottom surface and a side surface arranged around the bearing bottom surface, the water storage capacity of the bearing part can be increased, and the probability of the liquid on the bearing part flowing to other parts of the base station can be reduced. Furthermore, by connecting the first end of the return pipe to an opening arranged on one of the bearing bottom surface and the side surface, the liquid on the bearing part can be returned to the water storage tank through the return pipe.

[0016] In a possible implementation, the bearing bottom surface is an inclined surface inclined toward the water tank, and the low-position area is arranged on a side of the inclined surface close to the water tank.

[0017] By setting the bearing bottom surface as an inclined surface, the water on the bearing part can be easily gathered toward the low-position area, and by making the inclined surface inclined toward the water storage tank and setting the low-position area on the side of the inclined surface close to the water storage tank, the path of the return pipe can be shortened, and the efficiency of the liquid on the bearing part returning to water through the return pipe can be improved. In addition, since the path of the return pipe is shortened, the manufacturing cost of the return pipe can be reduced, thereby reducing the manufacturing cost of the base station and the cleaning system.

[0018] In a possible implementation, the return pipeline includes a first channel and a second channel; the first channel is located in the base, the second channel is located in the water tank, one end of the first channel extends to the bearing portion, the other end of the first channel is connected to one end of the second channel, and the other end of the second channel extends to a position higher than the position of the highest liquid level in the water tank.

[0019] By setting the return pipeline to include a first channel and a second channel, and setting the first channel in the base and the second channel in the water tank, the detachable connection between the water tank and the base can be facilitated, and the separate repair and maintenance of the base and the water tank can be facilitated, thereby improving the practicality of the base station.

[0020] By extending the other end of the second channel facing away from the first channel to a position higher than the position of the highest liquid level in the water tank, the liquid in the water tank can be prevented from flowing out through the second channel, and the backflow of the liquid in the water tank to the water on the supporting part can be prevented.

[0021] In a possible implementation, a first tubular structure is disposed in the water tank, and the second channel is provided in the first tubular structure; and a bottom surface of the water tank has a first opening communicating with the second channel.

[0022] A first tubular structure having a second channel inside is arranged in the water tank, and the first tubular structure is connected to a first opening on the bottom surface of the water tank, so that the first tubular structure is connected to the first channel, and the liquid on the bearing part flows into the water tank through the first tubular structure.

[0023] In a possible implementation, the base station further includes a supporting portion, the supporting portion is disposed on the base, the water tank is disposed on the base through the supporting portion, a portion of the first channel is located in the base, and another portion of the first channel is located in the supporting portion.

[0024] By arranging the water tank on the base through the support part, the water tank is supported by the support part, thereby improving the installation stability of the water tank on the base. By arranging the water tank on the support part, the space on the base station can be effectively utilized, and the space occupancy rate of the water tank on the base station can be reduced.

[0025] Furthermore, by setting the water tank on the base station through the support part, the height of the water tank from the ground is increased, which can make the filling and draining of the water tank more convenient. The user can fill and clean the water tank more easily, reducing the need for the user to bend or squat, thereby improving operational efficiency and convenience.

[0026] By arranging a part of the first channel in the base and the other part of the first channel in the support part, the return pipeline can be prevented from being exposed to the outside of the base station, thereby improving the rationality of the layout of the return pipeline on the base station and the neatness and beauty of the appearance of the base station.

[0027] In a possible implementation, the water tank is detachably connected to the support portion.

[0028] By detachably connecting the water tank and the support part, the detachable connection makes the connection between the water tank and the support part more flexible, convenient for disassembly and installation, conducive to the maintenance and cleaning of the water tank and the support part, and improves the maintenance efficiency of the equipment.

[0029] If the water tank or support needs to be replaced or upgraded, the detachable connection can make the replacement process easier and faster, without the need for large-scale disassembly, saving time and labor costs.

[0030] The detachable connection can make the connection between the water storage tank and the support part more compact, saving space and being conducive to better installation and layout of equipment in a limited space.

[0031] In a possible implementation, a second opening opposite to the first opening is provided on a surface of the support portion opposite to the water tank, the second opening is communicated with the first channel, and the first channel and the second channel are communicated through the second opening.

[0032] By opening a second opening on the surface of the support portion facing the water tank, the first channel and the second channel are connected through the second opening and the first opening, avoiding the first channel and the second channel from being connected through other structures, thereby improving the transmission efficiency in the underwater return pipeline.

[0033] In a possible implementation manner, a sealing structure is provided between the first opening and the second opening, and the sealing structure is used to seal a joint between the first opening and the second opening.

[0034] By providing a sealing structure at the joint of the first opening and the second opening, water can be prevented from leaking from the joint and the sealing of water transmission in the return pipe can be maintained. The sealing structure can effectively prevent water from leaking from the joint and ensure the stability and reliability of water transmission.

[0035] The design of the sealing structure can effectively prevent foreign matter from entering the return line through the joint, thus keeping the return line clean and hygienic.

[0036] In addition, the sealing structure can also reduce water loss at the joint, improve the water transmission efficiency in the return pipe, and prevent water leakage at the joint from affecting the electronic devices or circuits on the base station.

[0037] In a possible implementation, a second tubular structure is provided on the base and the support portion; a portion of the second tubular structure is located in the support portion, another portion of the second tubular structure is located in the base, and the first channel is provided in the second tubular structure.

[0038] By arranging the second tubular structure with the first channel in the base and the support part, the first channel is arranged in the base and the support part, avoiding the second tubular structure with the first channel being exposed outside the base station, and making the layout of the return pipeline more reasonable.

[0039] In a possible implementation, a hose is further included. The hose has a flow channel therein, and the flow channel forms the return line. One end of the hose extends to the bearing portion, and the other end of the hose extends into the water tank.

[0040] By using a hose and making the flow channel in the hose as a return line, one end of the hose extends to the load-bearing part and the other end of the hose extends into the water tank, so that the liquid on the load-bearing part can flow back into the water tank through the hose.

[0041] By using a hose, the setting position of the return pipe on the base station and the transmission path of water in the return pipe can be changed at will, which improves the adjustment flexibility of the return pipe and is more conducive to making the return pipe adapt to different layouts and installation environments on the base station, thereby improving the use flexibility and adjustability of the base station.

[0042] In addition, the use of hoses is easy and quick to install, and does not require complicated connections and fixation, which reduces the time and cost of installation. The hoses are easy to disassemble and replace, and can be easily maintained and cleaned, which reduces the complexity of operations during maintenance and improves the maintainability of the base station.

[0043] The hose has a certain buffering and energy-absorbing effect, which can reduce the vibration and noise generated when water flows in the hose, thereby improving the stability and comfort of the base station.

[0044] A second aspect of an embodiment of the present application provides a cleaning system, which includes a cleaning device and the base station as described above; the cleaning device includes a floor brush assembly and a clean water tank, and the clean water tank is arranged on the floor brush assembly;

[0045] The bearing part of the base station is adapted to the floor brush assembly and the clean water tank;

[0046] The return pipeline on the base station is used to discharge the liquid overflowing from the clean water tank onto the bearing part into the water storage tank on the base station.

[0047] The cleaning system provided in the embodiment of the present application arranges a clean water tank on the floor brush assembly and injects liquid into the clean water tank through the water storage tank. This can avoid the user from bending over significantly or squatting to add liquid to the clean water tank, reducing the difficulty and complexity of adding liquid to the clean water tank and improving the user experience. In the process of supplying water from the water storage tank to the clean water tank, if liquid overflows from the clean water tank onto the bearing part of the base station, the liquid overflowing from the bearing part can be returned to the water storage tank through a reflux pipe extending to the bearing part, thereby avoiding the overflowed liquid from affecting the electronic devices or circuits on the base station, thereby improving the working stability, safety and service life of the cleaning system.

[0048] Moreover, the reflux pipeline can also serve as an air passage during the process of supplying liquid from the water storage tank to the clean water tank, so as to facilitate air intake through the reflux pipeline during the process of supplying liquid from the water storage tank, thereby successfully completing the filling of liquid into the clean water tank; in the present application, the reflux pipeline can realize the reflux of liquid on the bearing part while realizing the liquid supply of the water storage tank, and the reflux pipeline has a simple structure and low cost.

[0049] Furthermore, by returning the liquid on the carrying part to the water storage tank through the reflux pipeline, the liquid on the carrying part can be reused, thereby reducing the waste of water resources, reducing the use cost of the cleaning system, and improving the practicality of the cleaning system.

[0050] In a possible implementation, an exhaust valve is provided on the clean water tank, and the exhaust valve is provided on a side close to a return pipeline on the base station, so that the liquid in the clean water tank overflows onto the bearing portion through the exhaust valve.

[0051] By arranging an exhaust valve on the clean water tank, the air in the clean water tank is exhausted outwards through the exhaust valve during the process of filling water into the clean water tank. The exhaust valve can ensure that the bubbles or gas inside the clean water tank are removed in time, and avoid the air in the clean water tank cannot be discharged in time, resulting in a high air pressure in the clean water tank and making it difficult to fill water into the clean water tank, thereby ensuring that the clean water in the water storage tank can fully flow into the clean water tank.

[0052] In a possible implementation, the bearing portion has a low-position area, the first end of the return pipeline extends to the low-position area, and the liquid discharged from the clean water tank through the exhaust valve flows to the low-position area.

[0053] By setting a low-level area on the bearing part, the water on the bearing part can be gathered toward the low-level area, and the first end of the return pipe can be extended to the low-level area, so that the liquid flowing out of the exhaust valve to the bearing part can be gathered to the low-level area, and the liquid in the low-level area can be further returned to the water storage tank through the return pipe, which is beneficial to improving the cleaning efficiency of the water on the bearing part and reducing processing time and cost.

[0054] In a possible implementation, when the cleaning device is located on the base station, a water storage tank provided on the base station can be used to fill the clean water tank with liquid.

[0055] By using the water storage tank on the base station to fill the clean water tank with water, the user can avoid the need for additional operations or additional tools to add water to the clean water tank on the cleaning equipment, thereby improving the ease of use of the cleaning system and making the user experience more convenient and comfortable.

[0056] In a possible implementation, the water storage tank has a water outlet, and the clean water tank has a water inlet, and the water inlet is connected to the water outlet.

[0057] By connecting the water storage tank and the clean water tank through the water outlet and the water inlet, the water in the water storage tank can flow directly into the clean water tank, thereby conveniently replenishing the clean water tank with water, avoiding the tedious steps of users manually adding water to the clean water tank, and improving the convenience of use of the cleaning equipment and user experience.

[0058] In a possible implementation, the base station further includes a water supply pipeline, a third end of the water supply pipeline is connected to the water outlet, and a fourth end of the water supply pipeline is connected to the water inlet.

[0059] By connecting the water inlet and the water outlet through the water supply pipe, it can be ensured that water flows smoothly from the water storage tank to the clean water tank, realizing the function of automatically replenishing the water source in the clean water tank, and improving the convenience and automation level of the cleaning equipment.

[0060] In a possible implementation, the flow area of ​​the return pipeline is greater than or equal to the flow area of ​​the water supply pipeline.

[0061] By making the flow area of ​​the return pipe greater than or equal to the flow area of ​​the water supply pipe, it can be ensured that the water flow rate accommodated by the return pipe is greater than or equal to the water flow rate accommodated by the water supply pipe, thereby preventing the water overflowing from the cleaning equipment onto the load-bearing part from being unable to flow back into the water storage tank in time due to the water supply volume being greater than the return water volume, thereby preventing the electronic components or circuits on the cleaning system from being damaged by water due to being soaked in water.

[0080] As described in the background technology, the existing floor washing system generally includes a base station and a cleaning device. When filling the clean water tank on the cleaning device with water or performing self-cleaning, there is a risk of liquid overflowing onto the base station bearing part and damaging the electronic components in the base station, thereby reducing the safety and working stability of the base station.

[0081] Generally, a liquid level monitoring device is provided on the clean water tank to monitor the liquid level in the clean water tank to prevent excessive water from being injected into the clean water tank and overflowing onto the base station. However, when the liquid level monitoring device fails, the liquid level changes in the floor brush assembly cannot be monitored, causing the water storage tank to continue to inject water into the clean water tank. When the liquid level reaches a certain height, the water in the clean water tank will overflow onto the base station, causing damage to the electronic devices or circuits on the base station. When a large amount of water overflows onto the base station, it will further overflow onto the indoor floor, causing damage to the floor. In addition, it is also possible that there is no liquid level monitoring device provided on the clean water tank. During the process of regularly filling the clean water tank with water, if there is a large amount of water remaining in the clean water tank, the water will also overflow onto the base station, resulting in the above-mentioned problems that need to be solved urgently.

[0082] In view of the above technical problems, the base station provided by the embodiment of the present application is provided with a floor brush assembly on a bearing part on the base, a water tank on the base, one end of the return pipe extends to the bearing part, and the other end of the return pipe extends into the water tank. In the process of the water tank supplying liquid to the target container, a negative pressure can be formed in the water tank, so that when liquid appears on the bearing part, the liquid enters the return pipe through the first end of the return pipe under the action of the negative pressure in the water tank, and flows into the water tank through the second end, thereby preventing the electronic devices or circuits on the base station from being damaged by the liquid on the bearing part, thereby improving the working stability and safety of the base station. Among them, the target container can be a clean water tank of a cleaning equipment, other external boxes that need to be supplied with water, etc.

[0083] Moreover, the reflux pipeline can also serve as an air passage during the process of the water tank supplying liquid to the target container, so as to facilitate the intake of air through the reflux pipeline during the process of the water tank supplying liquid, thereby successfully completing the liquid supply; the reflux pipeline in the present application can realize the reflux of the liquid on the load-bearing part on the basis of realizing the liquid supply of the water tank, and the reflux pipeline has a simple structure and low cost.

[0084] Furthermore, by returning the liquid on the carrying part to the water storage tank through the reflux pipe, the liquid on the carrying part can be reused, thereby reducing the waste of water resources, reducing the use cost of the cleaning system, and improving the practicality of the base station and the cleaning system.

[0085] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings 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 belong to the scope of protection of this application.

[0086] refer to Figure 1 and Figure 2 An embodiment of the present application provides a base station 10 , which may include a base 100 , a water tank 200 and a return pipeline 300 .

[0087] The base 100 has a bearing portion 110, and the bearing portion 110 is used to bear the floor brush assembly 21 of the cleaning device 20. The floor brush assembly 21 may have a clean water tank 22, and clean water can be stored in the clean water tank 22 to facilitate cleaning of the floor brush assembly 21.

[0088] refer to Figure 1The water tank 200 can be arranged on the base 100, and the water tank 200 can be arranged on the base 100 near the bearing part 110. The water tank 200 can inject liquid into the clean water tank 22 of the floor brush assembly 21. During the process of the water tank 200 injecting water into the clean water tank 22, when the liquid level in the clean water tank 22 reaches a preset height, continuing to inject water into the clean water tank 22 will cause the water in the clean water tank 22 to overflow through the exhaust valve on the clean water tank 22, and the overflowed water will flow onto the bearing part 110 of the base 100.

[0089] refer to Figure 2 The first end 310 of the return pipe 300 extends to the bearing portion 110 , and the second end 320 of the return pipe 300 extends into the water tank 200 , so that the liquid on the bearing portion 110 is discharged into the water tank 200 through the return pipe 300 .

[0090] In some embodiments, the water tank 200 can be connected to the outside through the return pipe 300 to achieve air pressure balance between the inside and outside of the water tank 200. When there is no water on the carrier 110, when the liquid level in the water tank 200 drops, the water tank 200 draws air from the external environment through the return pipe 300 to achieve air pressure balance between the inside and outside of the water tank 200.

[0091] In some embodiments, the base station 10 may also be provided with a suction device, which can act on the return pipe 300 to suck the water on the carrying part 110 into the water storage tank 200. When there is water on the carrying part 110, the suction device can start to work and act on the return pipe 300 to suck the liquid on the carrying part 110 into the water storage tank 200 through the return pipe 300.

[0092] The carrying portion 110 may be detected by a sensor to determine whether there is water on the carrying portion 110 .

[0093] If the water in the clean water tank 22 overflows onto the supporting portion 110 during the process of the water tank 200 filling the clean water tank 22, the water on the supporting portion 110 can be sucked into the water tank 200 by the negative pressure generated in the water tank 200 when the water level of the water tank 200 drops.

[0094] The base station 10 provided in the embodiment of the present application is configured such that a floor brush assembly 21 is disposed on a bearing portion 110 on a base 100, a water tank 200 is disposed on the base 100, one end of a return pipe 300 extends to the bearing portion 110, and the other end of the return pipe 300 extends into the water tank 200, so as to realize the reflux of liquid on the bearing portion 110 into the water tank 200 through the return pipe 300, thereby preventing electronic devices or circuits on the base station 10 from being damaged by water on the bearing portion 110, thereby improving the working stability and safety of the base station 10, and improving the working stability, practicality and service life of the cleaning system.

[0095] The reflux pipeline 300 can also serve as a gas passage during the process of the water storage tank 200 supplying liquid to the target container, so that air can be taken in through the reflux pipeline 300 during the process of the water storage tank 200 supplying liquid, thereby successfully completing the liquid supply. In the present application, the reflux pipeline 300 can realize the reflux of the liquid on the carrying part 110 on the basis of realizing the liquid supply of the water storage tank 200, and the reflux pipeline 300 has a simple structure and low cost.

[0096] Furthermore, by returning the liquid on the carrier 110 to the water tank 200 through the return pipe 300, the water on the carrier 110 can be reused, reducing the waste of water resources and the use cost of the cleaning system, thereby improving the practicality of the base station 10 and the cleaning system.

[0097] refer to Figure 2 In some embodiments, along the height direction of the water tank 200, the second end 320 of the return pipe 300 extends to a position higher than the position of the highest liquid level in the water tank 200. The highest liquid level may be the position of the liquid level when the water storage tank 200 has the maximum water storage capacity.

[0098] By extending the second end 320 of the return pipe 300 to a position in the water tank 200 that is higher than the position of the highest liquid level in the water tank 200, the second end 320 can be prevented from being below the liquid level of the clean water in the water tank 200, thereby preventing the liquid in the water tank 200 from entering the return pipe 300 and affecting the water return process of the return pipe 300, and facilitating the liquid on the bearing portion 110 to flow back into the water tank 200.

[0099] Furthermore, by making the second end 320 of the return pipe 300 extend to a position in the water tank 200 that is higher than the position of the highest liquid level in the water tank 200, it is also possible to prevent the liquid in the water tank 200 from entering the return pipe 300, so that the inside of the water tank 200 is connected with the outside through the return pipe 300, and the return pipe 300 is used as an air passage in the process of the water tank 200 supplying liquid to the target container, so that air can be taken in through the return pipe 300 during the process of the water tank 200 supplying liquid, thereby successfully completing the liquid supply.

[0100] In some embodiments, the water tank 200 may have a top cover, and there may be a gap between the position where the highest liquid level in the water tank 200 is located and the top cover, and the position to which the second end 320 of the return pipe 300 extends can be located within the gap, that is, the second end 320 of the return pipe 300 can be located between the top cover and the highest liquid level in the water tank 200.

[0101] By making the second end 320 of the return pipe 300 lower than the top cover, the second end 320 abutting against the top cover can be avoided to affect the liquid on the bearing part 110 to flow back into the water tank 200 through the return pipe 300, thereby improving the practicality of the base station 10.

[0102] In some embodiments, the water tank 200 is filled with liquid. When the liquid level in the water tank 200 decreases, negative pressure is formed in the water tank 200. The negative pressure can act on the return pipe 300 to make the liquid on the supporting part 110 flow into the water tank 200 through the return pipe 300.

[0103] By using the suction negative pressure generated in the water tank 200 when the liquid level in the water tank 200 is lowered, the water on the carrying part 110 is directly sucked into the water tank 200, avoiding the use of other suction equipment to suck the water on the carrying part 110 into the water tank 200, thereby reducing the manufacturing cost of the base station 10 and the cleaning system and improving the ease of use of the base station and the cleaning system.

[0104] Furthermore, by using the return pipe 300 as an air passage during the process of the water tank 200 supplying liquid to the target container, when the water tank 200 supplies liquid to the target container, the external air is sucked into the water tank 200 through the return pipe 300 by suction negative pressure, thereby successfully completing the liquid supply.

[0105] refer to Figure 1 and Figure 2 In some embodiments, the bearing portion 110 has a low area 111 along the height direction of the base 100, and the first end 310 of the return pipe 300 extends to the low area 111. Under the action of gravity, water on the bearing portion 110 can be collected in the low area 111 on the bearing portion 110.

[0106] By providing a low-position area 111 along the height direction of the base 100 on the bearing portion 110, water on the bearing portion 110 can be gathered toward the low-position area 111, and the first end 310 of the return pipe 300 can be extended to the low-position area 111, so that the water gathered in the low-position area 111 on the bearing portion 110 can be easily returned to the water storage tank 200 through the return pipe 300, which is beneficial to improving the cleaning efficiency of the water on the bearing portion 110 and reducing processing time and cost.

[0107] In a possible implementation, when the base station 10 is placed on the ground, a part of the supporting portion 110 can be closer to the ground than other areas, so that the area on the supporting portion 110 close to the ground forms a low-position area 111, and water on the supporting portion 110 can be collected in the low-position area 111. The low-position area and other areas can be connected by an inclined plane, so that water in other areas of the supporting portion 110 can be collected in the low-position area 111.

[0108] In one possible implementation, when the base station 10 is placed on the ground, the supporting portion 110 as a whole can be in an inclined state, and the area of ​​the supporting portion 110 close to the ground in the inclined state is a low-level area 111. Water on the supporting portion 110 will gather toward the low-level area 111 along the inclined direction under the action of gravity.

[0109] refer to Figure 1 In some embodiments, the low area 111 can be disposed close to the water tank 200 to shorten the path of the return pipe 300 and improve the efficiency of the return water, thereby further improving the cleaning efficiency of the water on the bearing portion 110 and reducing processing time and cost.

[0110] refer to Figure 1 In some embodiments, the bearing portion 110 may include a bearing bottom surface 112 and a side surface 113 arranged around the outer periphery of the bearing bottom surface 112 , one of the bearing bottom surface 112 and the side surface 113 may have an opening 114 , and the first end 310 of the return line 300 is connected to the opening 114 .

[0111] By configuring the bearing part 110 to include a bearing bottom surface 112 and a side surface 113 disposed around the bearing bottom surface 112, the water storage capacity of the bearing part 110 can be increased, and the probability of the water on the bearing part 110 flowing to other parts of the base station 10 can be reduced. Furthermore, by connecting the first end 310 of the return pipe 300 to the opening 114 disposed on one of the bearing bottom surface 112 and the side surface 113, the liquid on the bearing part 110 can be returned to the water storage tank 200 through the return pipe 300.

[0112] refer to Figure 1In some embodiments, the opening 114 can be opened on the supporting bottom surface 112 , or the opening 114 can be opened on the side surface 113 , and the opening 114 can also be opened on the side surface 113 close to the supporting bottom surface 112 .

[0113] By opening the opening 114 on the side 113 close to the bearing bottom surface 112 , the return pipe 300 can be easily used to clean the water on the bearing portion 110 whose liquid level is close to the bearing bottom surface 112 , thereby improving the cleaning effect of the water on the bearing portion 110 and reducing the accumulation of water on the bearing portion 110 .

[0114] In some embodiments, the floor brush assembly 21 can be placed in the bearing portion 110 and on the bearing bottom surface 112. By setting the side surface 113, the probability of the floor brush assembly 21 falling from the bearing portion 110 can be reduced, thereby improving the installation stability of the floor brush assembly 21 on the base station 10.

[0115] refer to Figure 1 In some embodiments, the bearing bottom surface 112 is an inclined surface inclined toward the water tank 200 , and the low area 111 is disposed on a side of the inclined surface close to the water tank 200 .

[0116] By setting the bearing bottom surface 112 as an inclined surface, the water on the bearing part 110 can be easily gathered toward the low-level area 111. By tilting the inclined surface toward the water tank 200 and setting the low-level area 111 on the side of the inclined surface close to the water tank 200, the path of the return pipe 300 can be shortened, thereby improving the efficiency of the liquid on the bearing part 110 returning to the water through the return pipe 300.

[0117] Furthermore, since the path of the return pipe 300 is shortened, the manufacturing cost of the return pipe 300 can be reduced, thereby reducing the manufacturing cost of the base station 10 and the cleaning system.

[0118] In some embodiments, the bearing bottom surface 112 can be tilted toward the location of the water tank 200, and the low area 111 is located at the end of the inclined surface closer to the ground, that is, the end of the inclined surface closer to the ground is arranged close to the water tank 200.

[0119] In some embodiments, the bearing bottom surface 112 is a partially inclined surface, and the inclined portion of the bearing bottom surface 112 can be set close to the water tank 200 so that water falling on the bearing portion 110 can gather at the inclined surface on the bearing bottom surface 112, and further flow to the return pipe 300 through the opening 114 opened in the low-position area 111.

[0120] refer to Figure 2 In some embodiments, the return line 300 may include a first channel 330 and a second channel 340 .

[0121] The first channel 330 is located in the base 100, and the second channel 340 is located in the water tank 200. One end of the first channel 330 extends to the bearing portion 110, and the other end of the first channel 330 is connected to one end of the second channel 340. The other end of the second channel 340 extends to a position higher than the position of the highest liquid level in the water tank 200.

[0122] By configuring the return line 300 to include a first channel 330 and a second channel 340, and configuring the first channel 330 to be disposed in the base 100 and the second channel to be disposed in the water tank 200, it is possible to facilitate the detachable connection between the water tank 200 and the base 100, facilitate the separate repair and maintenance of the base 100 and the water tank 200, and improve the practicality of the base station 10.

[0123] By extending the other end of the second channel 340 facing away from the first channel 330 to a position higher than the position of the highest liquid level in the water tank 200, the liquid in the water tank 200 can be prevented from flowing out through the second channel 340, and the backflow of the liquid in the water tank 200 to the water on the supporting portion 110 can be prevented.

[0124] In some embodiments, at least a portion of the first channel 330 can be disposed in the base 100 , one end of the first channel 330 can extend to the supporting portion 110 and communicate with the opening 114 opened on the supporting portion 110 , and the other end of the first channel 330 can communicate with one end of the second channel 340 .

[0125] The second channel 340 is disposed in the water tank 200, and one end of the second channel 340 can extend to the bottom of the water tank 200 and communicate with the first channel 330, and the other end of the second channel 340 can extend toward the top of the water tank 200 and extend to a position higher than the highest liquid level in the water tank 200.

[0126] In some embodiments, the first channel 330 and the second channel 340 can be two parts of a flow channel in a whole pipe. Alternatively, the first channel 330 can be formed as a flow channel in one pipe, and the second channel 340 can be formed as a flow channel in another pipe.

[0127] refer to Figure 2 and Figure 3 In some embodiments, a first tubular structure 210 is disposed in the water tank 200 , a second channel 340 is formed in the first tubular structure 210 , and a first opening 220 communicating with the second channel 340 is formed on the bottom surface of the water tank 200 .

[0128] By disposing a first tubular structure 210 having a second channel 340 inside the water tank 200, and connecting the first tubular structure 210 with the first opening 220 on the bottom surface of the water tank 200, the first tubular structure 210 is connected with the first channel 330, so that the liquid on the supporting part 110 flows into the water tank 200 through the first tubular structure 210.

[0129] In some embodiments, the first tubular structure 210 may be an injection-molded part, so that the first tubular structure 210 is injection-molded into the water storage tank 200 .

[0130] The first tubular structure 210 can also be connected to the water tank 200 in a detachable connection manner, and the first tubular structure 210 can be disassembled, repaired and replaced separately. For example, the first tubular structure 210 can be connected to the water tank 200 in a threaded connection manner, that is, the first opening 220 on the water tank 200 has an internal thread, one end of the first tubular structure 210 has an external thread, and the first tubular structure 210 is screwed into the first opening 220 on the water tank 200. For another example, the first tubular structure 210 can be directly inserted into the first opening 220 of the water tank 200.

[0131] In some embodiments, the first tubular structure 210 can also be connected to the water storage tank 200 by welding. Specifically, the outer peripheral wall of the first tubular structure 210 can be connected to the inner peripheral wall of the first opening 220 by welding.

[0132] refer to Figure 2 In some embodiments, the base station 10 may further include a support portion 400 , which is disposed on the base 100 , the water tank 200 is disposed on the base 100 through the support portion 400 , a portion of the first channel 330 is located in the base 100 , and another portion of the first channel 330 is located in the support portion 400 .

[0133] By placing the water tank 200 on the base 100 through the support 400, the water tank 200 is supported by the support 400, thereby improving the installation stability of the water tank 200 on the base 100. By placing the water tank 200 on the support 400, the space on the base 10 can be effectively utilized, and the space occupancy rate of the water tank 200 on the base 10 can be reduced.

[0134] Furthermore, by setting the water tank 200 on the base station 10 through the support part 400, the height of the water tank 200 from the ground is increased, which can make the filling and drainage of the water tank 200 more convenient. The user can fill and clean the water tank 200 more easily, reducing the need for the user to bend or squat, thereby improving operational efficiency and convenience.

[0135] By setting a part of the first channel 330 in the base 100 and setting the other part of the first channel 330 in the support part 400, it is possible to avoid the return pipe 300 being exposed to the outside of the base station 10, thereby improving the rationality of the layout of the return pipe 300 on the base station 10 and the neatness and beauty of the appearance of the base station 10.

[0136] refer to Figure 2 In some embodiments, one end of the first channel 330 extends to the bearing portion 110 and communicates with the opening on the bearing portion 110 , the other end of the first channel 330 can extend into the supporting portion 400 , and the end of the first channel 330 extending into the supporting portion 400 can communicate with the second channel 340 .

[0137] In some embodiments, the support portion 400 can be connected to the base 100 in a detachable manner, and a mounting position can be provided on the base 100 , and the support portion 400 can be detachably connected to the mounting position on the base 100 .

[0138] refer to Figure 2 In some embodiments, the water tank 200 and the support portion 400 can be connected in a detachable manner.

[0139] By detachably connecting the water tank 200 and the support part 400, the detachable connection makes the connection between the water tank 200 and the support part 400 more flexible, convenient for disassembly and installation, and conducive to the maintenance and cleaning of the water tank 200 and the support part 400, thereby improving the maintenance efficiency of the equipment.

[0140] If the water tank 200 or the support part 400 needs to be replaced or upgraded, the detachable connection can make the replacement process easier and faster, without the need for large-scale disassembly, thus saving time and labor costs.

[0141] The detachable connection can make the connection between the water tank 200 and the support part 400 more compact, saving space and facilitating better installation and layout of equipment in a limited space.

[0142] refer to Figure 3 and Figure 4 In some embodiments, a second opening 410 opposite to the first opening 220 is provided on the surface of the support portion 400 opposite to the water tank 200, and the second opening 410 can be connected to one end of the first channel 330 extending into the support portion 400, and the first channel 330 and the second channel 340 are connected through the second opening 410.

[0143] In a specific implementation, when the water tank 200 is disposed on the support portion 400 , the first opening 220 and the second opening 410 are connected to each other so that the first channel 330 and the second channel 340 are connected, and the liquid on the supporting portion 110 flows back into the water tank 200 through the first channel 330 and the second channel 340 .

[0144] By opening a second opening 410 on the surface of the support portion 400 facing the water tank 200, the first channel 330 and the second channel 340 are connected through the second opening 410 and the first opening 220, thereby avoiding the first channel 330 and the second channel 340 from being connected through other structures, thereby improving the transmission efficiency in the underwater return pipeline 300.

[0145] It is understandable that if the return line 300 includes a first channel 330 and a second channel 340 that are separated from each other, the joint between the first channel 330 and the second channel 340 must maintain good air-tightness, that is, the joint between the first opening 220 and the second opening 410 needs to have good air-tightness.

[0146] If the airtightness of the joint between the first opening 220 and the second opening 410 is poor, on the one hand, the water in the return pipe 300 will leak from the joint between the first opening 220 and the second opening 410. On the other hand, if the liquid on the carrier 110 is sucked into the water storage tank 200 through the return pipe 300 by means of negative pressure, leakage at the first opening 220 and the second opening 410 will cause the negative pressure in the return pipe 300 to disappear, thereby making it impossible to suck the water on the carrier 110 into the water storage tank 200 by means of negative pressure.

[0147] refer to Figure 4 In some embodiments, a sealing structure 500 is provided between the first opening 220 and the second opening 410 , and the sealing structure 500 is used to seal the joint between the first opening 220 and the second opening 410 .

[0148] By providing a sealing structure 500 at the joint of the first opening 220 and the second opening 410, it is possible to prevent water from leaking from the joint and maintain the sealing of water transmission in the return pipe 300. The sealing structure 500 can effectively prevent water from leaking from the joint and ensure the stability and reliability of water transmission.

[0149] The design of the sealing structure 500 can effectively prevent foreign matter from entering the return line 300 through the joint, thereby keeping the return line 300 clean and hygienic.

[0150] In addition, the sealing structure 500 can also reduce water loss at the joint, improve the water transmission efficiency in the return pipe 300 , and prevent the water leaking at the joint from affecting the electronic devices or circuits on the base station 10 .

[0151] refer to Figure 2 In a possible implementation, a second tubular structure 420 is provided on the base 100 and the support portion 400 , a portion of the second tubular structure 420 is located in the support portion 400 , another portion of the second tubular structure 420 is located in the base 100 , and the second tubular structure 420 has a first channel 330 therein.

[0152] By disposing a second tubular structure 420 having a first channel 330 in the base 100 and the support portion 400, the first channel 330 is disposed in the base 100 and the support portion 400, thereby avoiding the second tubular structure 420 having the first channel 330 being exposed to the outside of the base station 10, and making the layout of the return line 300 more reasonable.

[0153] In some embodiments, the second tubular structure 420 may be an injection molded part, so that the second tubular structure 420 is injection molded in the base 100 and the support portion 400. When the support portion 400 is injection molded on the base 100, the second tubular structure 420 can also be injection molded together with the support portion 400 and the base 100.

[0154] In some embodiments, the first tubular structure 210 and the second tubular structure 420 can both be injection molded parts. By setting the first tubular structure 210 and the second tubular structure 420 as injection molded parts, the assembly efficiency of the base station 10 can be improved and the manufacturing cost of the first tubular structure 210 and the second tubular structure 420 can be reduced.

[0155] In other embodiments, the base station 10 may further include a hose, which can replace the first tubular structure 210 and the second tubular structure 420 as injection molded parts. The hose has a flow channel, which is a return line 300. One end of the hose extends to the bearing portion 110, and the other end of the hose extends to the water tank 200. As an example, the hose may be a rubber tube.

[0156] By using a hose and making the flow channel in the hose as the return line 300, one end of the hose extends to the support portion 110, and the other end of the hose extends into the water tank 200, so that the liquid on the support portion 110 can flow back into the water tank 200 through the hose.

[0157] By using a hose, the setting position of the return pipe 300 on the base station 10 and the transmission path of water in the return pipe 300 can be changed at will, thereby improving the adjustment flexibility of the return pipe 300, making it more conducive to adapting the return pipe 300 to different layouts and installation environments on the base station 10, and improving the use flexibility and adjustability of the base station 10.

[0158] Furthermore, the hose is easy and quick to install, and does not require complicated connection and fixing, which reduces the time and cost of the installation process. The hose is easy to disassemble and replace, and can be easily maintained and cleaned, which reduces the complexity of the operation during the maintenance process and improves the maintainability of the base station 10.

[0159] The hose has certain buffering and energy-absorbing effects, which can reduce the vibration and noise generated when water flows in the hose, thereby improving the stability and comfort of the base station 10 .

[0160] refer to Figures 1 to 5 The embodiment of the present application further provides a cleaning system, which may include a cleaning device 20 and the base station 10 as described above. The cleaning device 20 may include a floor brush assembly 21 and a clean water tank 22, the clean water tank 22 is disposed on the floor brush assembly 21, and the bearing portion 110 of the base station 10 can be adapted to the floor brush assembly 21 and the clean water tank 22. The return line 300 on the base station 10 is used to discharge the liquid overflowing from the clean water tank 22 onto the bearing portion 110 of the base station 10 into the water storage tank 200 on the base station 10.

[0161] The cleaning system provided in the embodiment of the present application can prevent the water overflowing from the cleaning equipment 20 onto the carrying part 110 from affecting the electronic devices or circuits on the base station 10 by placing the floor brush assembly 21 in the cleaning device 20 on the bearing part 110 on the base station 10, and use the return pipe 300 to discharge the water overflowing from the cleaning device 20 onto the bearing part 110 into the water storage tank 200, thereby improving the working stability, practicality and service life of the cleaning system. In addition, the return pipe 300 can also serve as an air passage in the process of the water storage tank 200 supplying liquid to the clean water tank 22, so as to facilitate air intake through the return pipe 300 during the process of the water storage tank 200 supplying liquid, and thus smoothly complete the filling of the clean water tank 22; in the present application, the return pipe 300 can realize the reflux of the liquid on the bearing part 110 on the basis of realizing the liquid supply of the water storage tank 200, and the return pipe 300 has a simple structure and low cost.

[0162] Furthermore, by returning the liquid on the carrier 110 to the water storage tank 200 through the reflux pipe 300, the water on the carrier 110 can be reused, thereby reducing the waste of water resources, reducing the use cost of the cleaning system, and improving the practicality of the cleaning system.

[0163] By setting the clean water tank 22 on the floor brush assembly 21 and filling water into the clean water tank 22 through the water storage tank 200, the user can avoid bending over significantly or squatting to add water to the clean water tank 22, and can avoid the user's need for additional operations or additional tools to add water to the clean water tank 22 on the cleaning device 20, thereby reducing the difficulty of adding water to the clean water tank 22 and improving the user experience.

[0164] The water overflowing from the clean water tank 22 onto the bearing portion 110 is discharged into the water storage tank 200 through the return pipe 300, which can reduce the impact of the water overflowing from the clean water tank 22 on the electronic devices or circuits on the base station 10, improve the reuse rate of water, and reduce the waste of water resources.

[0165] In some embodiments, an exhaust valve (not shown) is provided on the clean water tank. The exhaust valve is provided on a side close to the return pipe 300 on the base station 10 , and the liquid in the clean water tank 22 overflows onto the bearing portion 110 through the exhaust valve.

[0166] By arranging an exhaust valve on the clean water tank 22, the air in the clean water tank 22 can be exhausted outwards through the exhaust valve during the process of filling liquid into the clean water tank 22. The exhaust valve can ensure that the bubbles or gas inside the clean water tank 22 are removed in time, and avoid the air in the clean water tank 22 not being able to be discharged in time, resulting in a high air pressure in the clean water tank 22 and being unfavorable for filling water into the clean water tank 22, thereby ensuring that the liquid in the water storage tank 200 can fully flow into the clean water tank 22.

[0167] Specifically, the exhaust valve is set on the side of the clean water tank 22, and the overflowing water through the exhaust valve can flow along the side wall of the clean water tank to the first end of the return pipe 300, so that the return pipe 300 can suck the overflowing water into the water storage tank 200.

[0168] In some embodiments, the bearing portion 110 has a low area 111 , the first end 310 of the return pipe 300 extends to the low area 111 , and the liquid discharged from the clean water tank 22 through the exhaust valve flows to the low area 111 .

[0169] In a specific example, water overflowing from the exhaust valve may flow along the side wall of the clean water tank to a low area on the carrying portion 110 .

[0170] By setting a low-position area 111 on the bearing portion 110, the water on the bearing portion 110 can be gathered toward the low-position area 111, and the first end 310 of the return pipe 300 can be extended to the low-position area 111, so that the liquid flowing out of the exhaust valve to the bearing portion 110 can be easily gathered to the low-position area 111, and the liquid in the low-position area 111 can be further returned to the water storage tank 200 through the return pipe 300, which is beneficial to improve the cleaning efficiency of the water on the bearing portion 110 and reduce processing time and cost.

[0171] In this embodiment, the clean water tank 22 can be arranged on a side of the floor brush assembly 21 close to the water storage tank 200. The clean water tank 22 can be directly matched with the bearing part 110 of the base station 10. The specific structure and arrangement of the clean water tank 22 are not limited.

[0172] As an example, the volume of the water storage tank 200 is greater than or equal to the volume of the clean water tank 22. This arrangement can effectively reduce the number of times the water storage tank 200 is filled with liquid and reduce the complexity of water supply.

[0173] In some embodiments, the water storage tank 200 has a water outlet, and the clean water tank 22 has a water inlet, and the water inlet is connected to the water outlet.

[0174] By connecting the water storage tank 200 and the clean water tank 22 through the water outlet and the water inlet, the water in the water storage tank 200 can flow directly into the clean water tank 22, thereby conveniently replenishing the clean water tank 22 with water, avoiding the tedious steps of the user manually adding water to the clean water tank 22, and improving the convenience of use of the cleaning device 20 and the user experience.

[0175] In some embodiments, the water outlet of the water storage tank 200 may be disposed on the bearing portion 110 , and the water inlet of the clean water tank 22 may be disposed at the bottom of the clean water tank 22 and matched with the water outlet.

[0176] As an example, a water inlet channel is provided between the water outlet of the water tank 200 and the water tank 200 , one end of the water inlet channel is connected to the water tank 200 , and the other end constitutes the water outlet.

[0177] In some embodiments, the base station 10 may further include a water supply pipeline, which may have a third end and a fourth end, wherein the third end of the water supply pipeline is connected to the water outlet, and the fourth end of the water supply pipeline is connected to the water inlet.

[0178] By connecting the water inlet and the water outlet through the water supply pipeline, it can ensure that water flows smoothly from the water storage tank 200 to the clean water tank 22, realize the function of automatically replenishing the water source of the clean water tank 22, and improve the convenience and automation level of the cleaning equipment 20.

[0179] Specifically, one end of the water supply pipeline is sealed and connected to the water outlet, and the other end is sealed and connected to the water inlet; thereby avoiding water leakage during the process of the water storage tank 200 filling the clean water tank 22 with water.

[0180] The base station 10 may further include a water pumping device, which is used to pump water in the water storage tank 200 through the water supply pipeline into the clean water tank 22 on the floor brush assembly 21. The efficiency of injecting water into the clean water tank 22 can be improved by providing the water pumping device.

[0181] In a possible implementation, the flow area of ​​the return pipeline 300 is greater than or equal to the flow area of ​​the water supply pipeline.

[0182] By making the flow area of ​​the return pipe 300 greater than or equal to the flow area of ​​the water supply pipe, it can be ensured that the water flow rate accommodated by the return pipe 300 is greater than or equal to the water flow rate accommodated by the water supply pipe, thereby preventing the water overflowing from the cleaning equipment 20 onto the carrying part 110 from being unable to flow back into the water tank 200 in time due to the water supply amount being greater than the return water amount, thereby preventing the electronic components or circuits on the cleaning system from being damaged by water due to being soaked in water.

[0183] In some embodiments, the return pipe 300 can be formed by a flow channel in a first circular pipe, and the water supply pipe can also be formed by a flow channel in a second circular pipe. The diameter of the first circular pipe can be larger than the diameter of the second circular pipe.

[0184] In some embodiments, the flow area may refer to the area of ​​a fluid passing through an object. As an example, in layman's terms, the flow area may refer to the area of ​​a cross section through which the fluid flows. Correspondingly, the flow area formula may refer to a formula for calculating the area of ​​a fluid passing through an object.

[0185] As an example, the flow area calculation formula may include the following:

[0186] First, for a circular tube or cylinder, the flow area calculation formula is:

[0187] A=mr^2;

[0188] Among them, A represents the flow area and r represents the radius of the cylinder.

[0189] Second, for pipes or objects with square or rectangular cross-sections, the flow area calculation formula is:

[0190] B = I * w;

[0191] Among them, B represents the flow area, 1 represents the length of the rectangle, and w represents the width of the rectangle.

[0192] Third, for objects with irregular shapes, a simplified approximate formula can be used to calculate the flow area.
