Referring to fig. 1 to 5 together, a water tank assembly according to an embodiment of the present application will now be described. The water tank assembly comprises:

a clear water tank 100;

a sewage tank 200;

the self-cleaning device 300 comprises a cleaning pipeline 310, a water pump 320 and a spray header 330, wherein the spray header 330 is arranged in the sewage tank 200, one end of the cleaning pipeline 310 is communicated with the clean water tank 100, the other end of the cleaning pipeline 310 is communicated with the spray header 330, the water pump 320 is arranged on the cleaning pipeline 310, and the water pump 320 is used for pumping clean water in the clean water tank 100 to the spray header 330 and flushing the inner side wall of the sewage tank 200 by the spray header 330.

Generally, a washing robot is provided with a floor washing assembly and a water absorption rake, the floor washing assembly is used for spraying water to a floor and wiping the floor for cleaning, and the water absorption rake is used for absorbing sewage generated by wiping and cleaning the floor, so that the work flow of floor cleaning is completed.

In addition, referring to fig. 1 and 2, a clean water tank 100 and a sewage tank 200 are provided on the washing robot, the clean water tank 100 is used for storing clean water, and the clean water tank 100 is communicated with the floor washing assembly in the washing robot through a clean water pipeline for pumping clean water to the floor washing assembly for use by the floor washing assembly to clean the floor.

The sewage tank 200 is used for storing sewage, and the sewage tank 200 is communicated with the suction rake through a sewage pipeline 500, specifically, the outlet of the sewage pipeline 500 in the sewage tank 200 of the sewage pipeline 500 is positioned at the top of the side wall of the sewage tank 200, so as to store the sewage sucked by the suction rake therein; further, a vacuum pumping device is arranged in the sewage tank 200, and is used for vacuumizing the inside of the sewage tank 200 to generate negative pressure, and meanwhile, as the sewage pipeline 500 is communicated with the sewage tank 200, when negative pressure is generated in the sewage tank 200, negative pressure is also generated in the sewage pipeline 500, and the negative pressure in the sewage pipeline 500 acts on the water-absorbing rakes to pump and pump sewage on the floor contacted by the water-absorbing rakes into the sewage tank 200, so that the drying of the floor and the storage of the sewage are realized.

Specifically, in the cleaning robot, since a large negative pressure exists in the sewage tank 200 during cleaning, when sewage flows out from the outlet of the sewage pipe 500 at the top of the sidewall of the sewage tank 200 into the sewage tank 200, the flow rate of the sewage is fast due to the negative pressure, and the water level in the sewage tank 200 is very low, generally 0, at the beginning of cleaning, so that when sewage flows into the sewage tank 200 from the outlet of the sewage pipe 500, the sewage is very easily splashed onto the sidewall of the sewage tank 200 due to the very low water level in the sewage tank 200. Further, since various impurities, such as hair, sludge, dust, etc., are often mixed in the sewage, and such impurities are generally sticky, when the impurities are splashed onto the side wall of the sewage tank 200, the impurities are adhered and adsorbed on the side wall of the sewage tank 200 to form dirt, and over time, the dirt is gradually condensed and smells along with the increase of the dirt and the repeated water intake and drainage of the sewage tank 200, resulting in a great difficulty in subsequent cleaning.

So, in the process that sewage flows into the sewage tank 200, the shower head 330 can continuously spray high-pressure clean water to the inside wall of the sewage tank 200, thereby timely removing impurities splashed to the inside wall of the sewage tank 200, wherein the removed impurities flow to the bottom of the sewage tank 200 along the inner side wall of the sewage tank 200 along with water flow, and the sewage in the sewage tank 200 is intensively discharged after the operation of the cleaning robot is completed.

Further, the shower head 330 is used for spraying high-pressure mist-like clean water to the fixed direction of the inner side wall of the sewage tank 200. Specifically, the showerhead 330 may have the following several arrangements. In some arrangements, the showerhead 330 may be a single showerhead 330 disposed on an inner sidewall of the waste tank 200; or, in other arrangement modes, two or more spray headers 330 may be arranged, each spray header 330 is arranged at a certain distance, and each spray header 330 sprays high-pressure atomized clear water in a fixed direction in the sewage tank 200; or, the spray header 330 may also be set to be a hollow pipe, the hollow pipe is disposed around each inner sidewall of the sewage tank 200, and a plurality of water outlets are spaced at one side of the hollow pipe facing the inner sidewall of the sewage tank 200, so that when the water pump 320 is started, the spray header 330 can spray high-pressure mist clean water to each inner sidewall of the sewage tank 200 at the same time, thereby improving the cleaning efficiency.

In conclusion, the water tank assembly of the application has the advantages that the cleaning robot can clean the inner side wall of the sewage tank 200 in time by splashing and splashing the left-over dirt through the spray head 330 in the cleaning process, the deposition of the dirt on the side wall can be reduced, and the cleaning is not needed to be performed manually after the operation is completed, so that the maintenance cost is reduced, and meanwhile, the sanitation condition in the sewage tank 200 can be improved.
