[0050] The spray unit 50 includes a water pipe 445 rotatably arranged with a pipe joint 449, and a nozzle 447 is fixedly arranged at the output end of the water pipe 445. The nozzle 447 is connected to the water pipe 445. The nozzle 447 is suitable for when the water pump pumps out the cleaning liquid in the water tank 441, and then reaches the nozzle 447 through the water pipe 445, and finally sprays it out from the nozzle 447;
