A first cleaning mechanism and a second cleaning mechanism are arranged at the center inside the liquid storage tank. The second cleaning mechanism is arranged above the first cleaning mechanism. The first cleaning mechanism includes a first support roller rotatably connected, and a first sponge sleeve is arranged on the outer wall of the first support roller. The second cleaning mechanism includes a second support roller rotatably connected, and a second sponge sleeve is arranged on the outer wall of the second support roller. Cleaning rollers rotatably connected are arranged on the inner wall of the liquid storage tank below both ends of the transmission workbench assembly.

[0007] Further, the transmission workbench assembly includes a driving roller and a driven roller rotatably connected to the liquid storage tank. Transmission belts are fitted on the outer walls of the driving roller and the driven roller. A scraper is horizontally arranged at one end of the top of the liquid storage tank, and a servo motor is arranged on the outer wall of one end of the liquid storage tank. The output shaft of the servo motor is fixedly connected to one end of the driving roller.

[0008] Furthermore, the two cleaning rollers are respectively driven and connected to the driving roller and the driven roller through synchronous belt assemblies.

[0009] Furthermore, on both sides of the outer wall of the first support roller, first support frames are symmetrically arranged in a rotatable connection. At one end of the first support frame away from the first support roller, a brush roller is arranged in a rotatable connection. A first torsion spring is arranged between the first support frame and the first support roller.

[0010] Furthermore, on both sides of the outer wall of the second support roller, second support frames are symmetrically arranged in a rotatable connection.
