When the sliding block 10 moves towards the water spraying pipe 32, the ejector rod 40 at the bottom of the sliding block contacts with the top plate 39 and pushes the top plate 39 to move, so that the moving plate 36 is driven to move, the second spring 37 and the telescopic rod 38 shrink in the process, the cleaning liquid in the water storage box 34 flows into the water spraying pipe 32 through the first water conveying pipe 33 under the extrusion of the moving plate 36 and is sprayed out from the spray head of the water spraying pipe 32, so that the cleaning roller 9 is washed, when the sliding block 10 gradually moves away from the water spraying pipe 32, the second spring 37 gradually rebounds and pushes the moving plate 36 and the top plate 39 to move, negative pressure is generated inside the water storage box 34 when the moving plate 36 moves, the cleaning liquid in the water tank 41 flows into the water storage box 34 through the second water conveying pipe 42 under the action of the negative pressure so as to facilitate subsequent use, when the filter screen 7 is washed, the water pump 25 is closed, the liquid in the piston pipe 26 is disappeared at the moment, the first spring 29 rebounds, the piston plate 27 and the piston rod 28 are pushed to move, the shutter 24 is driven, so that the shutter 24 is prevented from blocking the drain pipe 23, and harmful gas is discharged through the shutter 23.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes and modifications may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
