[0024] With the above solution, by providing the cleaning device 8 , the interior of the tank body 1 can be cleaned when the connecting block 803 and the bracket 804 rotate, thereby avoiding dirt residue on the inner wall of the tank body 1 .

[0025] refer to Figure 4 A cavity 9 is provided inside the bracket 804 , and a telescopic component 10 is provided inside the cavity 9 . The telescopic component 10 can contact the surface of the inner wall of the tank body 1 .

[0026] The above solution is adopted: by setting the cavity 9 and the telescopic component 10, the telescopic component 10 can be accommodated, and then the telescopic component 10 can be adjusted according to the situation inside the tank body 1, and then the dirt can be cleaned.

[0027] refer to Figure 4 The telescopic assembly 10 includes an electric cylinder 1001, an extension arm 1002 and two cleaning wheels 1003. The electric cylinder 1001 is fixedly connected to the inside of the cavity 9, the extension arm 1002 is slidably connected to the inside of the cavity 9, and is fixedly connected to the output end of the electric cylinder 1001.

When cleaning, water or cleaning liquid can be poured in through the water inlet, so that the inside of the tank body 1 can be effectively cleaned. After cleaning, the water can be discharged through the discharge pipe 5.
