Description

Technical Field

[0001] The present application relates to the technical field of cleaning systems, and in particular to a cleaning system. Background Art

[0002] As people's living standards improve, home cleaning has gradually entered an era of automation and intelligence. The cleaning equipment that has emerged, such as floor scrubbers and sweeping robots, can alleviate people's fatigue during home cleaning.

[0003] Existing cleaning systems generally include a base station and cleaning equipment. When filling the clean water tank on the cleaning equipment with water, there is a risk of liquid overflowing onto the base station and damaging the electronic components in the base station, thereby reducing the safety and working stability of the base station. Utility Model Content

[0004] An embodiment of the present application provides a cleaning system, which can, when the liquid level in the clean water tank is higher than a preset liquid level, allow the liquid in the clean water tank to flow back to the water storage tank through a return pipe, thereby preventing the liquid in the clean water tank from overflowing and causing electronic components or circuits on the base station to be soaked in water, thereby improving the working stability of the base station, as well as improving the working stability and safety of the cleaning system.

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

[0006] An embodiment of the present application provides a cleaning system, which includes: a base station, on which a water tank is provided; a cleaning device, which includes a floor brush assembly and a clean water tank, and the clean water tank is provided on the floor brush assembly, and the floor brush assembly can be placed on the base station; the water storage tank is at least used to inject liquid into the clean water tank; a return water pipeline, one end of the return water pipeline extends into the clean water tank, and the other end extends into the water storage tank; when the liquid level in the clean water tank is higher than a preset liquid level, the liquid in the clean water tank flows back to the water storage tank through the return water pipeline.

[0007] The embodiment of the present application provides a cleaning system, which is provided with a water storage tank on a base station, and the clean water tank of the cleaning device is provided on a floor brush assembly, so that when the floor brush assembly is provided on the base station, liquid can be injected into the clean water tank through the water storage tank, which can avoid the user from bending over or squatting to add water to the clean water tank, thereby reducing the difficulty of adding water to the clean water tank and improving the user experience. In addition, by providing a return water pipeline connecting the clean water tank and the water storage tank, when the liquid level in the clean water tank is higher than the preset liquid level during the process of the water storage tank supplying liquid to the clean water tank, the liquid in the clean water tank flows back to the other end of the return water pipeline located in the water storage tank through one end of the return water pipeline located in the clean water tank, which can effectively prevent the water in the clean water tank from overflowing onto the base station, and can avoid damage to the electronic devices or circuits on the base station, thereby improving the working stability and safety of the cleaning system and reducing the waste of water resources.

[0008] Based on the above technical solution, the present application can also be improved as follows.

[0009] In a possible implementation, an exhaust valve is provided on the clean water tank, the exhaust valve connects the clean water tank and the outside, and the exhaust valve is used to exhaust air during the liquid filling process of the clean water tank; in the height direction of the clean water tank, the exhaust valve is set at a position higher than the preset liquid level.

[0010] By arranging an exhaust valve on the clean water tank so that the exhaust valve exhausts air outwards during the process of filling liquid into the clean water tank, the exhaust valve can ensure that bubbles or gas inside the clean water tank are removed in time, avoiding the air in the clean water tank from not being able to be discharged in time, resulting in a high air pressure in the clean water tank and being unfavorable for filling liquid into the clean water tank, thereby ensuring that the liquid in the water storage tank can fully flow into the clean water tank.

[0011] By setting the exhaust valve at a position higher than the preset liquid level, the water in the clean water tank can be prevented from flowing out of the exhaust valve to the base station outside the clean water tank before flowing back into the water storage tank through the return pipe, thereby preventing the water in the clean water tank from overflowing.

[0012] In a possible implementation, a liquid level monitoring device is provided in the clean water tank; the liquid level monitoring device is used to detect the liquid level in the clean water tank; in the height direction of the clean water tank, the position of the preset liquid level is higher than the position of the liquid level monitoring device.

[0013] By arranging a liquid level monitoring device in the clean water tank, the liquid level in the clean water tank can be monitored at any time, which can avoid manual real-time checking of the liquid level in the clean water tank, save manpower, improve the automation degree of the cleaning system, and the convenience of use of the cleaning system.

[0014] Furthermore, in the height direction of the clean water tank, the position of the preset liquid level is higher than the position of the liquid level monitoring device, so that when the liquid level monitoring device fails, the water in the clean water tank can flow back to the water storage tank through the return pipe.

[0015] In a possible implementation, during the process of the water storage tank injecting liquid into the clean water tank, the air pressure in the clean water tank is greater than the air pressure in the water storage tank.

[0016] During the process of injecting liquid into the clean water tank from the water storage tank, the gas pressure in the clean water tank is made greater than the gas pressure in the water storage tank, so that a positive pressure is formed in the return water pipeline from the clean water tank to the water storage tank, and during the process of water in the clean water tank flowing back to the water storage tank through the return water pipeline, the liquid in the clean water tank is pressed from the return water pipeline to the water storage tank by the positive pressure, thereby improving the efficiency of water returning from the clean water tank to the clean water tank.

[0017] In a possible implementation, one end of the return pipe located in the clean water tank extends to the plane where the preset liquid level is located, and the position to which one end of the return pipe located in the water storage tank extends is higher than the position of the highest liquid level in the water storage tank.

[0018] By extending one end of the return pipe in the clean water tank to the plane where the preset liquid level is located, the liquid level in the clean water tank can flow back to the water storage tank through the return pipe when it is higher than the preset liquid level, thereby reducing the chance of liquid overflowing from the clean water tank.

[0019] By extending one end of the return water pipe to a position inside the water tank that is higher than the position of the highest liquid level in the water tank, it is possible to avoid the end of the return water pipe located inside the water tank being below the liquid level in the water tank, thereby preventing the liquid in the water tank from entering the return water pipe and affecting the return process of the return water pipe, and facilitating the liquid in the clean water tank to flow back into the water tank.

[0020] In a possible implementation, the water storage tank is provided with an air port, the air port connects the water storage tank with the outside, and the air port is used to take in air during the process of the water storage tank filling the clean water tank;

[0021] In the height direction of the water storage tank, the position to which one end of the return water pipeline located in the water storage tank extends is lower than the setting position of the air outlet.

[0022] By setting the air outlet, when the water storage tank is supplying liquid to the clean water tank, the position where the return pipe extends to can form a negative pressure, which can help to draw the liquid in the return pipe into the water storage tank. It can also cooperate with the positive pressure formed in the clean water tank to further improve the efficiency of the liquid in the clean water tank returning to the water storage tank through the return pipe.

[0023] In a possible implementation, the cleaning system also includes a water inlet pipe; one end of the water inlet pipe is connected to the clean water tank, and the other end of the water inlet pipe is connected to the water storage tank, and the water storage tank injects liquid into the clean water tank through the water inlet pipe; the flow area of ​​the return water pipe is greater than or equal to the flow area of ​​the water inlet pipe.

[0024] By setting a water inlet pipeline, the water storage tank can inject liquid into the clean water tank through the water inlet pipeline. When the water storage tank is filling water into the clean water tank, the positive pressure formed in the clean water tank and the negative pressure formed in the water storage tank make the water inlet speed consistent with the water return speed. By setting the flow area of ​​the return water pipeline to be greater than or equal to the flow area of ​​the water inlet pipeline, it can be ensured that the water flow rate accommodated by the return water pipeline is greater than or equal to the water flow rate accommodated by the water inlet pipeline, so as to avoid the liquid in the clean water tank from overflowing to the base station due to the water supply volume being greater than the return water volume, thereby preventing the electronic devices or circuits on the base station from being damaged by water.

[0025] In a possible implementation, the return water pipeline includes a first channel; the first channel is arranged in the clean water tank, the first end of the first channel is located at the preset liquid level, and the second end of the first channel is used to communicate with the water storage tank; when the liquid level in the clean water tank is higher than the first end of the first channel, the first channel can guide the liquid in the clean water tank to flow back to the water storage tank.

[0042] By setting the second channel as a three-section interconnected structure including a first sub-channel, a second sub-channel and a third sub-channel, it is possible to implement a separate layout of the first sub-channel, the second sub-channel and the third sub-channel in the second channel to adapt to the complex structure on the base station, thereby improving the flexibility of use of the second channel and the flexibility of use of the return pipe.

[0043] Furthermore, since the second channel includes the first sub-channel, the second sub-channel and the third sub-channel, the first sub-channel, the second sub-channel and the third sub-channel can be repaired and replaced separately, thereby further reducing the repair cost of the return water pipeline.

[0047] By arranging a second tubular structure having a third channel inside the water tank, the water tank is connected to the second channel through the second tubular structure. By arranging the first channel in the second tubular structure, the transmission stability of the liquid in the third channel can be improved, thereby improving the stability of the liquid in the water tank returning to the water tank through the third channel.

The second sealing structure can effectively prevent liquid from leaking from the joint and ensure the stability and reliability of water transmission.

[0050] By providing the second sealing structure, it is also possible to effectively prevent foreign matter from entering the water return pipe through the joint, thereby keeping the water return pipe clean and hygienic.

[0053] The cleaning system includes an alarm component to sound an alarm when the clean water tank returns water to the water storage tank, which can promptly remind the user that there is a risk of overflow in the clean water tank so that the user can deal with it in time, reducing the chance of overflow in the clean water tank and improving the practicality and safety of the cleaning system.

[0086] As described in the background technology, the existing cleaning system generally includes a base station and cleaning equipment. When filling the clean water tank on the cleaning equipment with water, there is a risk of liquid overflowing onto the base station and damaging the electronic components in the base station, thereby reducing the safety and working stability of the base station.

[0087] Generally, a water level monitoring device is installed in the clean water tank to monitor the water level in the clean water tank and prevent excessive water from overflowing onto the base station. However, when the water level monitoring device fails, the water level change in the clean water tank cannot be monitored, resulting in the water storage tank continuously injecting liquid into the clean water tank. When the water 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.

[0088] In response to the above technical problems, an embodiment of the present application provides a cleaning system. The cleaning system arranges a water storage tank on a base station, and arranges the clean water tank of the cleaning equipment on a floor brush assembly, so that when the floor brush assembly is arranged on the base station, liquid can be injected into the clean water tank through the water storage tank. This can avoid the user from bending over significantly or squatting to add water to the clean water tank, thereby reducing the difficulty of adding water to the clean water tank and improving the user experience.

[0089] By setting a return water pipe so that one end of the return water pipe extends into the clean water tank and the other end of the return water pipe is in the water storage tank, when the liquid level in the clean water tank is higher than the preset liquid level, the liquid in the clean water tank can flow back to the end of the return water pipe located in the water storage tank through the end of the return water pipe located in the clean water tank, thereby preventing water in the clean water tank from overflowing onto the base station, preventing damage to electronic devices or circuits on the base station, and reducing the waste of water resources.

[0090] 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.

[0091] refer to Figure 1 and Figure 2 An embodiment of the present application provides a cleaning system, which may include a base station 100, a cleaning device 200 and a return water pipeline 300.

[0092] The base station 100 may include a water tank 110 , in which clean water can be stored.

[0093] The cleaning device 200 may include a floor brush assembly 210 and a clean water tank 220 . The clean water tank 220 is disposed on the floor brush assembly 210 . The floor brush assembly 210 can be placed on the base station 100 , so that the clean water tank 220 can also be disposed on the base station 100 through the floor brush assembly 210 .

[0094] The water tank 110 is at least used to inject liquid into the clean water tank 220. By arranging the water tank 110 on the base station 100, the water in the water tank 110 can flow directly into the clean water tank 220, thereby conveniently replenishing the clean water tank 220 with water, avoiding the tedious steps of the user needing to manually add water to the clean water tank 220, and avoiding the need to inject liquid into the clean water tank 220 on the floor brush assembly 210 through an external pipeline, thereby improving the ease of use and user experience of the cleaning device 200, improving the ease of use of the base station 100, and saving the user's physical strength.

[0095] The water tank 110 can be connected to the base station 100 in a detachable manner to achieve separate maintenance and replacement of the water tank 110 , thereby improving the convenience of use of the base station 100 .

[0096] In some embodiments, the clean water tank 220 can be disposed close to the water storage tank 110 , thereby shortening the flow distance of the liquid injected from the water storage tank 110 into the clean water tank 220 and improving the efficiency of injecting liquid from the water storage tank 110 into the clean water tank 220 .

[0097] One end of the return pipe 300 extends into the clean water tank 220, and the other end extends into the water storage tank 110. When the liquid level in the clean water tank 220 is higher than the preset liquid level, the liquid in the clean water tank 220 flows back into the water storage tank 110 through the return pipe 300.

[0098] By setting up a return water pipe 300 connecting the clean water tank 220 and the water storage tank 110, when the water storage tank 110 supplies liquid to the clean water tank 220, if the liquid level in the clean water tank 220 is higher than the preset liquid level, the liquid in the clean water tank 220 can flow back to the other end of the return water pipe 300 located in the water storage tank 110 through one end of the return water pipe 300 located in the clean water tank 220, thereby effectively preventing the water in the clean water tank 220 from overflowing onto the base station 100 and preventing damage to the electronic devices or circuits on the base station 100, thereby improving the working stability and safety of the cleaning system and reducing the waste of water resources.

[0099] In some embodiments, the preset liquid level can be lower than the top wall of the clean water tank 220 in the height direction. The preset liquid level can be understood as the maximum safe filling level in the clean water tank 220. When the liquid level in the clean water tank 220 is higher than the preset liquid level, the risk of water overflowing in the clean water tank 220 is relatively high, which has a greater impact on the base station 100.

[0100] In some embodiments, the portion of the return pipe 300 extending into the clean water tank 220 can be arranged close to the water storage tank 110, thereby shortening the distance of the liquid returning from the clean water tank 220 to the water storage tank 110, thereby improving the efficiency of the liquid returning from the clean water tank 220 to the water storage tank 110, and improving the practicality of the cleaning system.

[0101] refer to Figure 2 and Figure 3 In a possible implementation, an exhaust valve 221 is provided on the clean water tank 220, and the exhaust valve 221 connects the clean water tank 220 and the outside world. The exhaust valve 221 is used to exhaust air during the liquid filling process of the clean water tank 220. In the height direction of the clean water tank 220, the setting position of the exhaust valve 221 is higher than the preset liquid level position.

[0102] By arranging an exhaust valve 221 on the clean water tank 220 so that the exhaust valve 221 exhausts air outwards during the process of filling liquid into the clean water tank 220, the exhaust valve 221 can ensure that the bubbles or gas inside the clean water tank 220 are removed in time, and avoid the air in the clean water tank 220 cannot be discharged in time, resulting in a high air pressure in the clean water tank 220 and being not conducive to filling liquid into the clean water tank 220, thereby ensuring that the liquid in the water storage tank 110 can fully flow into the clean water tank 220.

[0103] refer to Figure 3 In some embodiments, in the height direction of the clean water tank 220, the exhaust valve 221 can be set in the clean water tank 220 in an area close to the top of the clean water tank 220, or the exhaust valve 221 can be set at the top of the clean water tank 220 to prevent the water in the clean water tank 220 from overflowing to the outside of the clean water tank 220 through the exhaust valve 221, thereby improving the water storage capacity of the clean water tank 220.

[0104] By setting the position of the exhaust valve 221 higher than the preset liquid level, the water in the clean water tank 220 can be prevented from flowing out of the exhaust valve 221 to the base station 100 outside the clean water tank 220 before returning to the water storage tank 110 through the return pipe 300, thereby preventing the water in the clean water tank 220 from overflowing.

[0105] refer to Figure 2 and Figure 3 In a possible implementation, a liquid level monitoring device 222 is provided in the clean water tank 220 . The liquid level monitoring device 222 is used to detect the liquid level in the clean water tank 220 .

[0106] By setting a liquid level monitoring device 222 in the clean water tank 220, the liquid level in the clean water tank 220 can be monitored at any time, and manual real-time checking of the liquid level in the clean water tank 220 can be avoided, which saves manpower and improves the automation degree of the cleaning system and the convenience of use of the cleaning system.

[0107] In some embodiments, the liquid level monitoring device 222 may include a liquid level sensor. When the water storage tank 110 injects liquid into the clean water tank 220 , the liquid level monitoring device 222 can monitor the liquid level in the clean water tank 220 at any time.

[0108] The liquid level monitoring device 222 may also include a control unit that is communicatively connected to the liquid level sensor. When the liquid level sensor detects that the liquid level in the clean water tank 220 reaches a preset liquid level, the control unit can prevent the liquid in the water storage tank 110 from flowing into the clean water tank 220, so as to avoid the liquid level in the clean water tank 220 being too high and causing the liquid in the clean water tank 220 to overflow.

[0109] The liquid level monitoring device 222 may also include a prompting component. When the liquid level sensor detects that the liquid level in the clean water tank 220 reaches a preset liquid level, the prompting component can issue a prompt to remind the user that the liquid level in the clean water tank 220 has reached the preset liquid level. In some embodiments, the prompting component may be a prompting sound component, or a prompting light component.

[0110] In the height direction of the clean water tank 220 , the preset liquid level position is higher than the position of the liquid level monitoring device 222 .

[0111] In the height direction of the clean water tank 220, the preset liquid level is located higher than the position of the liquid level monitoring device 222, so that when the liquid level monitoring device 222 fails, the water in the clean water tank 220 can flow back to the water storage tank 110 through the return pipe 300.

[0112] In some embodiments, during the process of the water storage tank 110 injecting liquid into the clean water tank 220 , the air pressure in the clean water tank 220 is greater than the air pressure in the water storage tank 110 .

[0113] During the process of injecting liquid into the clean water tank 220 from the water storage tank 110, the gas pressure in the clean water tank 220 is made greater than the gas pressure in the water storage tank 110, so that a positive pressure is formed in the return pipe 300 from the clean water tank 220 to the water storage tank 110, and during the process of the water in the clean water tank 220 flowing back to the water storage tank 110 through the return pipe, the liquid in the clean water tank 220 is pressed from the return pipe 300 to the water storage tank 110 by the positive pressure, thereby improving the efficiency of returning water from the clean water tank 220 to the clean water tank 220.

[0114] In some embodiments, the water storage tank 110 is provided with an air port, the air port connects the water storage tank 110 with the outside, and the air port is used to take in air during the process of the water storage tank 110 filling the clean water tank 220;

[0115] In the height direction of the water storage tank 110 , the position to which one end of the return water pipe 300 located in the water storage tank 110 extends is lower than the setting position of the air outlet.

[0116] By setting the air outlet, when the water storage tank 110 supplies liquid to the clean water tank 220, the position where the return pipe 300 extends can form a negative pressure, which can help to suck the liquid in the return pipe 300 into the water storage tank 110, and can also cooperate with the positive pressure formed in the clean water tank to further improve the efficiency of the liquid in the clean water tank 220 returning to the water storage tank 110 through the return pipe 300.

[0117] During the process of injecting liquid into the clean water tank 220 from the water tank 110, as the liquid level in the water tank 110 drops, negative pressure will be generated in the water tank 110. This negative pressure can help to draw the liquid in the return pipe 300 into the water tank 110, thereby further improving the efficiency of the liquid in the clean water tank 220 returning to the water tank 110 through the return pipe 300.

[0118] Furthermore, the air inlet takes in air during the process of the water storage tank 110 supplying liquid to the clean water tank 220 to ensure the air pressure balance in the water storage tank 110, thereby successfully completing the liquid supply.

[0119] refer to Figure 3 In some embodiments, one end of the return water pipe 300 located in the clean water tank 220 extends to the plane where the preset liquid level is located.

[0120] By extending one end of the return pipe 300 located in the clean water tank 220 to the plane where the preset liquid level is located, the liquid level in the clean water tank 220 can flow back to the water storage tank 110 through the return pipe 300 when it is higher than the preset liquid level, thereby reducing the probability of liquid overflow in the clean water tank 220.

[0121] refer to Figure 2 In some embodiments, the position to which one end of the return pipe 300 located in the water tank 110 extends is higher than the position of the highest liquid level in the water tank 110 .

[0122] By extending one end of the return pipe 300 to a position in the water tank 110 that is higher than the position of the highest liquid level in the water tank 110, it is possible to avoid the end of the return pipe 300 located in the water tank 110 being below the liquid level in the water tank 110, thereby preventing the liquid in the water tank 110 from entering the return pipe 300 and affecting the return process of the return pipe 300, and facilitating the liquid in the clean water tank 220 to flow back into the water tank 110.

[0123] refer to Figure 2In some embodiments, the water tank 110 may have a top cover 114, and there may be a gap between the position where the highest liquid level in the water tank 110 is located and the top cover 114, and the position to which one end of the return pipe 300 extends in the water tank 110 can be located between the gap, that is, the end of the return pipe 300 extending into the water tank 110 can be located between the top cover 114 and the highest liquid level in the water tank 110.

[0124] By extending the return pipe 300 to one end of the water storage tank 110 below the top cover 114, it is possible to avoid the end of the return pipe 300 abutting against the top cover 114 and affecting the water in the clean water tank 220 from flowing back into the water storage tank 110 through the return pipe 300, thereby improving the practicality of the cleaning system.

[0125] In a possible implementation, the water tank 110 has a vent 113 connecting the inside of the water tank 110 and the outside of the water tank 110. In the height direction of the water tank 110, the position of one end of the return pipe 300 extending into the water tank 110 is lower than the position of the vent 113.

[0126] By providing the air port 113 in the water tank 110 , the water tank 110 can be connected with the outside through the air port 113 to achieve air pressure balance between the inside and outside of the water tank 110 .

[0127] Furthermore, by extending one end of the return pipe 300 into the water tank 110 in the height direction of the water tank 110 so as to be lower than the position of the air outlet 113 , liquid returning to the water tank 110 can be prevented from overflowing from the air outlet 113 .

[0128] Furthermore, if the air outlet 113 is provided on the top cover 114 of the water tank 110, by making the position of one end of the return pipe 300 extending into the water tank 110 lower than the position of the air outlet 113, it is possible to prevent the end of the return pipe 300 toward the air outlet 113 from abutting against the top cover 114, thereby preventing the liquid in the return pipe 300 from flowing back into the water tank 110 when the end of the return pipe 300 abuts against the top cover 114.

[0129] refer to Figure 2 and Figure 4 In some embodiments, the return water pipeline 300 may include a first channel 310, the first channel 310 is disposed in the clean water tank 220, the first end 311 of the first channel 310 is located at a preset liquid level, and the second end 312 of the first channel 310 is used to communicate with the water storage tank 110. When the liquid level in the clean water tank 220 is higher than the first end 311 of the first channel 310, the first channel 310 can guide the liquid in the clean water tank 220 to flow back to the water storage tank 110.

[0130] The return water pipeline 300 may include a first channel 310, and the first end 311 of the first channel 310 extends to a preset liquid level, so that when the liquid level in the clean water tank 220 is higher than the first end 311, the liquid in the clean water tank 220 can flow back to the water storage tank 110 through the first channel 310.

[0131] In some embodiments, the first channel 310 can extend into the clean water tank 220, and one end of the first channel 310 located in the clean water tank 220 can extend toward the top of the clean water tank 220, and the port of one end of the first channel 310 located in the clean water tank 220 can be set toward the top of the clean water tank 220.

[0132] On the basis of the above embodiment, in the height direction of the clean water tank 220 , one end of the first channel 310 extending into the clean water tank 220 can be located between the liquid level monitoring device 222 and the exhaust valve 221 .

[0133] refer to Figure 2 and Figure 3 In some embodiments, a first tubular structure 223 is disposed in the clean water tank 220 , and a first channel 310 is provided in the first tubular structure 223 .

[0134] By arranging the first tubular structure 223 having the first channel 310 inside the clean water tank 220, the clean water tank 220 is connected to the water storage tank 110 through the first tubular structure 223. By arranging the first channel 310 in the first tubular structure 223, the transmission stability of the liquid in the first channel 310 can be improved, thereby improving the stability of the water in the clean water tank 220 returning to the water storage tank 110 through the first channel 310.

[0135] In some embodiments, the first tubular structure 223 may be an injection-molded part, so that the first tubular structure 223 is injection-molded into the water storage tank 110 .

[0136] By configuring the first tubular structure 223 as an injection molded part, it is possible to avoid installing the first tubular structure 223 separately, thereby improving the assembly efficiency of the base station 100 and thus improving the assembly efficiency of the cleaning system, and reducing the manufacturing cost of the first tubular structure 223 .

[0137] refer to Figure 3 and Figure 4 In a possible implementation, the bottom surface of the clean water tank 220 has a first opening 224 , and the second end 312 of the first channel 310 is in communication with the first opening 224 .

[0138] By setting a first opening 224 on the ground of the clean water tank 220 and connecting the second end 312 of the first channel 310 facing away from the first end 311 with the first opening 224, the liquid entering from the first end 311 of the first channel 310 can flow out through the first opening 224 on the bottom surface of the clean water tank 220 and further flow into the water storage tank 110.

[0139] The first tubular structure 223 can also be connected to the water tank 110 in a detachable connection manner, and the first tubular structure 223 can be disassembled, repaired, and replaced separately. For example, the first tubular structure 223 can be connected to the water tank 110 in a threaded connection manner, that is, the first opening 224 on the water tank 110 has an internal thread, one end of the first tubular structure 223 has an external thread, and the first tubular structure 223 is screwed into the first opening 224 on the water tank 110. For another example, the first tubular structure 223 can be directly inserted into the first opening 224 of the water tank 110.

[0140] In some embodiments, the first tubular structure 223 can also be connected to the water storage tank 110 by welding. Specifically, the outer peripheral wall of the first tubular structure 223 can be connected to the inner peripheral wall of the first opening 224 by welding.

[0141] refer to Figure 2 and Figure 5 In some embodiments, the water return pipeline 300 may further include a second channel 320 . The third end of the second channel 320 is connected to the second end 312 of the first channel 310 , and the fourth end of the second channel 320 is used to communicate with the water storage tank 110 .

[0142] The return water pipeline 300 may include a second channel 320, and the third end of the second channel 320 is connected to the second end 312 of the first channel 310, and the fourth end of the second channel 320 is connected to the water storage tank 110, so that the water storage tank 110 and the clean water tank 220 can be connected through the first channel 310 and the second channel 320, so as to realize the backflow of water in the clean water tank 220 through the first channel 310 and the second channel 320.

[0143] Furthermore, by configuring the return water pipeline 300 as the first channel 310 and the second channel 320 that are connected, the first channel 310 and the second channel 320 can be arranged separately to adapt to the complex structure of the base station 100. The first channel 310 and the second channel 320 can be repaired and replaced separately, thereby reducing the maintenance cost of the return water pipeline 300.

[0144] In some embodiments, the second channel 320 can be disposed inside the base station 100 , which can improve the aesthetics of the base station 100 and the cleaning system and improve the rationality of the layout of the cleaning system compared to disposing the second channel 320 outside the base station 100 .

[0145] refer to Figure 2 and Figure 4 In some embodiments, the cleaning system may further include a first sealing structure 500 , which is located at the first opening 224 and is used to seal a joint between the third end of the second channel 320 and the first opening 224 .

[0146] By providing the first sealing structure 500 at the first opening 224, the joint between the third end of the second channel 320 and the second end 312 of the first channel 310 is sealed by the first sealing structure 500, so that clean water can be prevented from leaking from the joint and the sealing of the liquid in the water return pipe 300 can be maintained. The first sealing structure 500 can effectively prevent the liquid from leaking from the joint and ensure the stability and reliability of water transmission.

[0147] By providing the first sealing structure 500 , it is also possible to effectively prevent foreign matter from entering the water return pipe 300 through the joint, thereby keeping the water return pipe 300 clean and hygienic.

[0148] In addition, the first sealing structure 500 can also reduce the loss of liquid at the joint, improve the transmission efficiency of the liquid in the return pipe 300, and prevent the liquid leaking from the joint from affecting the electronic devices or circuits on the base station 100.

[0149] refer to Figure 2 In some embodiments, the first sealing structure 500 may be an elastic sealing ring, which is disposed on the outer peripheral side of the first opening 224 and the third end. When the first opening 224 and the third end are butted, the sealing ring will undergo a certain elastic deformation. Under the action of the elastic restoring force, the side of the elastic sealing ring facing the first opening 224 can be pressed against the surface where the first opening 224 is located to seal the butt joint between the elastic sealing ring and the first opening 224. The side of the elastic sealing ring facing the third end can be pressed against the surface where the third end is located to seal the butt joint between the elastic sealing ring and the third end, thereby achieving sealing of the butt joint between the first opening 224 and the third end.

[0150] refer to Figure 2In some embodiments, the base station 100 may include a base 120 and a support portion 130, the support portion 130 is disposed on the base 120, the water storage tank 110 is disposed on the support portion 130, and the base 120 is adapted to be matched with the floor brush assembly 210. A portion of the second channel 320 is disposed on the support portion 130, and another portion of the second channel 320 is disposed on the base 120.

[0151] By adapting the floor brush assembly 210 to the base 120 , the installation stability of the floor brush assembly 210 on the base station 100 can be improved.

[0152] By placing the water tank 110 on the base 120 through the support 130, the water tank 110 is supported by the support 130, thereby improving the installation stability of the water tank 110 on the base 120. By placing the water tank 110 on the support 130, the space on the base 100 can be effectively utilized, and the space occupancy rate of the water tank 110 on the base 100 can be reduced.

[0153] Furthermore, by setting the water tank 110 on the base 120 through the support part 130, the height of the water tank 110 from the ground is increased, which can make the filling and draining of the water tank 110 more convenient. The user can fill and clean the water tank 110 more easily, reducing the need for the user to bend or squat, thereby improving operational efficiency and convenience.

[0154] refer to Figure 2 and Figure 5 In some embodiments, the second channel 320 may include a first sub-channel 321 , a second sub-channel 322 , and a third sub-channel 323 which are arranged in the base station 100 .

[0155] The first sub-channel 321, the second sub-channel 322 and the third sub-channel 323 are connected in sequence. The end of the first sub-channel 321 facing away from the second sub-channel 322 is connected to the first channel 310, the second sub-channel 322 is connected to the end of the first sub-channel 321 facing away from the first channel 310, the other end of the second sub-channel 322 is connected to one end of the third sub-channel 323, and the other end of the third sub-channel 323 is connected to the third channel 330.

[0156] By setting the second channel 320 to a structure including three connected sections including the first sub-channel 321, the second sub-channel 322 and the third sub-channel 323, it is possible to implement a separate layout of the first sub-channel 321, the second sub-channel 322 and the third sub-channel 323 in the second channel 320 to adapt to the complex structure on the base station 100, thereby improving the flexibility of use of the second channel 320 and the flexibility of use of the return pipe 300.

[0157] Furthermore, the second channel 320 may include a first sub-channel 321 , a second sub-channel 322 and a third sub-channel 323 , so that the first sub-channel 321 , the second sub-channel 322 and the third sub-channel 323 can be repaired and replaced separately, further reducing the maintenance cost of the return pipe 300 .

[0158] refer to Figure 5 In some embodiments, the base 120 has a third tubular structure 121, which is formed by injection molding in the base 120, and has a first subchannel 321 in the third tubular structure 121. By forming the third tubular structure 121 by injection molding in the base 120, the assembly efficiency of the base station 100 can be improved, thereby improving the assembly efficiency of the cleaning system, and reducing the manufacturing cost of the third tubular structure 121.

[0159] The base 120 has a hose 123, and the flow channel in the hose 123 forms the second sub-channel 322. By using the hose 123 and making the flow channel in the hose 123 as the second sub-channel 322, the setting position of the second sub-channel 322 in the base 120 and the flow path of the liquid in the second sub-channel 322 can be changed at will, which improves the adjustment flexibility of the second sub-channel 322 and is more conducive to adapting the return pipe 300 to different layouts and installation environments on the base station 100. As an example, the hose can be a rubber tube.

[0160] Furthermore, the hose 123 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 123 is easy to disassemble and replace, and can be easily maintained and cleaned, which reduces the complexity of operation during maintenance and improves the maintainability of the cleaning system.

[0161] The hose 123 has certain buffering and energy-absorbing effects, which can reduce the vibration and noise generated when the liquid flows in the hose 123, thereby improving the stability and comfort of the cleaning system.

[0162] The support portion 130 has a fourth tubular structure 122 therein. The fourth tubular structure 122 is formed in the support portion 130 by injection molding. The fourth tubular structure 122 has a third sub-channel 323 therein.

[0163] By injection molding the fourth tubular structure 122 in the base 120 , the assembly efficiency of the base station 100 can be improved, thereby improving the assembly efficiency of the cleaning system, and reducing the manufacturing cost of the fourth tubular structure 122 .

[0164] refer to Figure 2 and Figure 5In some embodiments, the return pipe 300 may further include a third channel 330, which is disposed in the water storage tank 110. The fifth end of the third channel 330 is connected to the fourth end of the second channel 320, and the sixth end of the third channel 330 extends into the water storage tank 110, and the second channel 320 is connected to the water storage tank 110 through the third channel 330.

[0165] In some embodiments, the sixth end of the third channel 330 extends to a position in the water tank 110 that is higher than the position of the highest liquid level in the water tank 110 .

[0166] The return water pipeline 300 may include a third channel 330, and the fifth end of the third channel 330 may be connected to the fourth end of the second channel 320, so that the water storage tank 110 and the support portion 130 can be easily connected in a detachable manner, and the first channel 310, the second channel 320 and the third channel 330 of the return water pipeline 300 can be repaired and replaced separately, thereby further reducing the maintenance cost of the return water pipeline 300.

[0167] refer to Figure 2 In some embodiments, the water tank 110 has a second tubular structure 111 therein, and the second tubular structure 111 has a third channel 330 therein.

[0168] By disposing the second tubular structure 111 having the third channel 330 inside in the water tank 110, the water tank 110 is connected to the second channel 320 through the second tubular structure 111. By disposing the first channel 310 in the second tubular structure 111, the transmission stability of the liquid in the third channel 330 can be improved, thereby improving the stability of the liquid in the water tank 110 returning to the water tank 110 through the third channel 330.

[0169] refer to Figure 2 In some embodiments, the surface of the support portion 130 facing the water storage tank 110 has a second opening 131, and the second opening 131 is connected to the second channel 320. The bottom surface of the water storage tank 110 has a third opening 112, and the third opening 112 is connected to the third channel 330. A second sealing structure 600 is provided between the second opening 131 and the third opening 112, and the second sealing structure 600 is used to seal the joint between the second opening 131 and the third opening 112.

[0170] By providing the second sealing structure 600 at the second opening 131, the joint between the second opening 131 and the third opening 112 is sealed by the second sealing structure 600, so that liquid can be prevented from leaking from the joint, and the sealing of the liquid in the return pipe 300 can be maintained. The second sealing structure 600 can effectively prevent liquid from leaking from the joint, and ensure the stability and reliability of liquid transmission.

[0171] By providing the second sealing structure 600 , it is also possible to effectively prevent foreign matter from entering the water return pipe 300 through the joint, thereby keeping the water return pipe 300 clean and hygienic.

[0172] In addition, the second sealing structure 600 can also reduce the loss of liquid at the joint, improve the transmission efficiency of the liquid in the return pipe 300, and prevent the liquid leaking from the joint from affecting the electronic devices or circuits on the base station 100.

[0173] In some embodiments, the second sealing structure 600 may be the same structure as the first sealing structure 500. For example, both the second sealing structure 600 and the first sealing structure 500 may be elastic sealing rings. When the second sealing ring is an elastic sealing ring, the elastic sealing ring can seal the joint between the second opening 131 and the third opening 112.

[0174] refer to Figure 2 In some embodiments, the cleaning system may further include a water inlet pipe 400. One end of the water inlet pipe 400 is connected to the clean water tank 220, and the other end of the water inlet pipe 400 is connected to the water storage tank 110. The water storage tank 110 injects liquid into the clean water tank 220 through the water inlet pipe 400, and the flow area of ​​the return water pipe 300 is greater than or equal to the flow area of ​​the water inlet pipe 400.

[0175] By providing the water inlet pipe 400, the water storage tank 110 can inject liquid into the clean water tank 220 through the water inlet pipe 400. By making the flow area of ​​the return water pipe 300 greater than or equal to the flow area of ​​the water inlet pipe 400, it can be ensured that the water flow rate accommodated by the return water pipe 300 is greater than or equal to the water flow rate accommodated by the water inlet pipe 400, and it is avoided that the excessive liquid in the clean water tank 220 cannot be discharged from the clean water tank 220 and overflows to the base station 100 due to the water supply volume being greater than the return water volume, thereby preventing the electronic devices or circuits on the base station 100 from being damaged due to soaking in water, and the practicality and service life of the cleaning system can be improved.

[0176] 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.

[0177] As an example, the flow area calculation formula may include the following:

[0178] First, for a circular tube or cylinder, the flow area calculation formula is:

[0179] A=mr^2;

[0180] Among them, A represents the flow area and r represents the radius of the cylinder.

[0181] Second, for pipes or objects with square or rectangular cross-sections, the flow area calculation formula is:

[0182] B = I * w;

[0183] Among them, B represents the flow area, 1 represents the length of the rectangle, and w represents the width of the rectangle.

[0184] Third, for objects with irregular shapes, a simplified approximate formula can be used to calculate the flow area.

[0185] In some embodiments, the return pipe 300 can be formed by a flow channel in a first circular pipe, and the inlet pipe 400 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 to achieve a flow area of ​​the return pipe 300 that is larger than the flow area of ​​the inlet pipe 400.

[0186] refer to Figure 5 In some embodiments, the cleaning system may further include a water pumping device 700 , which is used to transport the water in the water storage tank 110 to the clean water tank 220 through the water inlet pipe 400 .

[0187] By using the pumping device 700 to pump the liquid in the water tank 110 into the clean water tank 220 through the water inlet pipe 400, the efficiency of injecting liquid from the water tank 110 into the clean water tank 220 can be significantly improved, thereby improving the practicality and working efficiency of the cleaning system.

[0188] In a possible implementation, the cleaning system may further include an alarm component, and the alarm component is used to sound an alarm when the clean water tank 220 returns water to the water storage tank 110 .

[0189] The cleaning system may also include an alarm component to sound an alarm when the clean water tank 220 returns water to the water storage tank 110, thereby promptly reminding the user that there is a risk of overflow in the clean water tank 220 so that the user can take timely action, thereby reducing the probability of overflow in the clean water tank 220 and improving the practicality and safety of the cleaning system.

[0190] In some embodiments, the alarm component can be disposed on the base station 100. For example, the alarm component can be disposed on the base 120 of the base station 100 or inside the base 120, the alarm component can also be disposed on the support portion 130, or the alarm component can also be disposed on the return pipe 300.

[0191] In some embodiments, the alarm component can warn by emitting a warning sound, such as a buzzer, or by a change in light, such as a flashing light.

[0192] In a possible implementation, the alarm component may include a sensor, an alarm, and a first control device. The first control device is respectively connected to the sensor and the alarm for communication, the sensor is used to detect the state of the liquid in the return pipe 300 in real time, and send the state information of the liquid to the first control device, and the first control device is used to control the alarm to be turned on or off according to the state of the liquid in the return pipe 300.

[0193] For example, when the sensing element detects that liquid flows in the return pipe 300, the first control device can control the alarm to turn on according to the liquid state in the return pipe 300 at this time. When the sensing element detects that there is no liquid flowing in the return pipe 300, the first control device can control the alarm in the turned-on state to turn off, or the first control device can control the alarm in the turned-off state to remain in the turned-off state.

[0194] The alarm component may include a sensor, an alarm and a first control device, so as to detect the liquid filling in the return pipe 300 through the sensor, and control the alarm to turn on or off according to the liquid state in the return pipe 300 through the first control device, thereby simplifying the structure of the alarm component, reducing the cost of the alarm component, and thereby reducing the manufacturing cost of the cleaning system.

[0195] In some embodiments, the sensor may be disposed in the water return pipe 300 to detect the liquid state in the water return pipe 300 in real time. The alarm may be disposed on the base 120, the support 130 or the water tank 110 on the base station 100.

[0196] In a possible implementation, the cleaning system may further include a water inlet control component, which is communicatively connected to the water pumping device 700 , and is used to control the opening or closing of the water pumping device 700 .

[0197] By setting up a water inlet control component so that the water inlet control component is communicated with the water pumping device 700, it is possible to control the opening and closing of the water pumping device 700 through the water inlet control component to realize the control of the injection of liquid from the water storage tank 110 into the clean water tank 220, thereby improving the flexibility and automation of the cleaning system and further improving the practicality of the cleaning system.

[0198] In some embodiments, when the brush assembly 210 and the clean water tank 220 are placed on the base station 100, the water inlet control assembly can control the opening or closing of the water pumping device 700 according to the change of the liquid level in the clean water tank 220. Alternatively, the water inlet control assembly can control the opening or closing of the water pumping device 700 according to the total time of the water storage tank 110 injecting liquid into the clean water tank 220.

[0199] In a possible implementation, the water inlet control assembly may include a timing device and a second control device. The timing device can be arranged in the water inlet pipeline 400, the timing device is used to detect the injection time, and the second control device is used to control the opening or closing of the water pump device 700 according to the injection time.

[0200] The water inlet control component may include a timing device and a second control device, which uses the timing device to detect the injection time, and controls the opening and closing of the pumping device according to the injection time through the second control device. The cleaning system can judge the state of the water storage tank 110 injecting liquid into the clean water tank 220 according to the injection time, so that when the injection time is long, the second control device can control the water pumping device 700 to be closed, thereby controlling the injection time of the water storage tank 110 into the clean water tank 220, thereby improving the practicality and automation of the cleaning system and reducing the probability of liquid overflow in the clean water tank 220.
