Wet cleaning of the transparent cover plate (4): S31, continue to push the cover plate (5) to the other end of the mounting frame (1) until the protrusion (12) contacts the inner wall of the mounting frame (1); S32, the protrusion (12) drives the slider (35) to move in the slide groove (34) and is stuck between the mounting seat (29) and the cover plate (5), so that the sponge (30) moves downward to contact the transparent cover plate (4); S33, at the same time, the side plate (25) pushes the push rod (17) upward, the piston plate (18) squeezes the No. 1 spring (19) and enters the fixed box (20), allowing the water in the water tank (7) to flow out through the circular hole (21) and wet the sponge (30); S34, when the cover plate (5) is reset, the transparent cover plate (4) is cleaned with a wet sponge (30); S35, after the cover plate (5) is completely reset, the piston plate (18) is reset under the action of the first spring (19) to re-block the drainage hole (10) to prevent water loss; S36, the slider (35) moves laterally under the push of the fixing bar (24), so that the protrusion (12) is separated from the mounting seat (29), and the mounting seat (29) is reset under the action of the second spring (26).
