Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Referring to fig. 1 to 3, a water tank 100 provided in an embodiment of the present application will now be described. The water tank 100 includes a sewage tank 1, a clean water tank 2, and a tank cover 3. Wherein the sewage tank 1 is provided with a containing chamber 10, and the top of the sewage tank 1 is an open end. The clean water tank 2 may be made of a flexible deformable material, for example, the clean water tank 2 may be a plastic bag or a nylon bag, etc., which is not limited only herein. The clean water tank 2 can be installed in the accommodating chamber 10, so that the volume of the accommodating chamber 10 occupied by the clean water tank 2 can be reduced.

Referring to fig. 3, a plurality of plugboards 31 are arranged on an annular array on the outer side wall of the water tank cover 3, and plugholes 310 are formed in each plugboard 31; correspondingly, the lock catches 11 are mounted at the outer edge of the top of the sewage tank 1 at positions corresponding to the respective insertion plates 31. The plurality of plugboards 31 can be inserted into the corresponding lock catches 11, and each lock catch 11 is matched and clamped with the corresponding jack 310, so that the water tank cover 3 and the sewage tank 1 are fixedly connected, and the water tank cover 3 and the sewage tank 1 can be detachably connected.

Referring to fig. 3, a handle 32 is provided at a middle position of the top of the tank cover 3, so that an operator can lift the water tank 100 through the handle 32, and the handling is facilitated.

Referring to fig. 2, a water inlet 12 and an air extraction opening 13 are respectively provided on the sewage tank 1, and the water inlet 12 and the air extraction opening 13 are respectively communicated with the accommodating chamber 10. Specifically, an extension part 14 protrudes outward from the right side of the top of the sewage tank 1, and the water inlet 12 and the air extraction opening 13 are respectively opened on the extension part 14, thereby facilitating connection with external equipment through a pipe. For example, the water inlet 12 may be connected to a water storage tank of the cleaning robot through a pipe, and the pumping port 13 may be connected to a pumping device through a pipe. When the air extraction device extracts air, the air in the sewage tank 1 is extracted, and negative pressure is formed in the sewage tank 1. In the negative pressure state, sewage in the water storage tank can be absorbed into the sewage tank 1 through the pipe and the water inlet 12.

With this structure, the check valve 4 can ensure that the clear water tank 2 has no difference between internal and external pressure and does not expand or contract.

With this structure, the clean water tank 2 is communicated with the accommodating chamber 10 through the check valve 4, the gas in the clean water tank 2 can enter the sewage tank 1, and the gas in the sewage tank 1 cannot enter the clean water tank 2. When the water inlet 12 is connected with the cleaning robot through a pipeline, the air extraction opening 13 is connected with external air extraction equipment and extracts air, and in the process that negative pressure is gradually formed inside the sewage tank 1, air in the clean water tank 2 enters the sewage tank 1 through the one-way valve 4, so that the pressure in the clean water tank 2 is kept the same as the pressure in the sewage tank 1, namely, the pressure difference between the inside and outside of the clean water tank 2 does not exist, the clean water tank 2 cannot expand due to the pressure difference, liquid in the sewage tank 1 cannot be extruded, the water level in the sewage tank 1 cannot be influenced, and the detection accuracy of the water level detection device on the water level in the sewage tank 1 is improved.

The first connection 221 may be used for drainage and the second connection 222 may be used for injection. When the water injection and drainage operations are simultaneously performed, the water injection amount is smaller than the drainage amount, so that the water in the clean water tank 2 is ensured to be insufficient to be filled. With this structure, by installing the first connection member 221 and the second connection member 222 on the tank body 21, respectively, the first connection member 221 can discharge the gas in the clean water tank 2 into the sewage tank 1 through the connection pipe 223 by the check valve 4; the second connector 222 can be connected with the pipeline to fill clear water into the clear water tank 2.
