[0072] With this structure, when the cleaning roller 31 moves from below the tooth column 29 to above, the sliding block 40 moves upward, and the sliding block 40 drives the squeezing block 46 to move upward. The squeezing block 46 squeezes the elastic liquid storage bag 56, so that the cleaning liquid in the elastic liquid storage bag 56 is sprayed onto the surface of the glass plate 32 through the spray pipe 45; and when the cleaning roller 31 moves from above the tooth column 29 to below, the spray pipe 45 can remain inoperative.

[0073] A controller is also fixed on the frame 1, and the solenoid valve 1 58, the solenoid valve 2 52 and the water pump 53 are all connected to the controller through lines; in this embodiment, the controller adopts a single-chip microcomputer available on the market, and the program of the single-chip microcomputer to control the solenoid valve and the pump is existing, and the program does not need to be re-edited.

[0074] With this structure, the actions of the solenoid valve 1 58, the solenoid valve 2 52 and the water pump 53 can be controlled by the controller, and the degree of intelligence is high.

[0075] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
