After the flushing is completed, the driving component drives the needle valve 31 to rotate, and at this time the needle valve 31 is connected to the moving block 40. The rotation of the needle valve 31 drives the rotary cutting component and the moving block 40 to move simultaneously, so that the moving block 40 scrapes off the residual paint on the chamber 30, pushes the residual paint to the nozzle, and then flushes it again with water, thereby improving the cleaning efficiency and effect of the cleaning chamber 30. When the painting is finished If the paint on the inner wall of the chamber 30 is forgotten to be flushed in time, the paint has dried on the inner wall of the chamber 30. At this time, the needle valve 31 is separated from the moving block 40, and the driving component drives the needle valve 31 to rotate.
