A partition 719 is fixedly connected to the inner wall of the filter box 703, and an air transfer pipe 704 is fixedly connected to the surface of the partition 719. A water tank 705 is provided on the side of the filter box 703 and the partition 719 close to each other, and an exhaust pipe 706 is fixedly connected to the side wall of the filter box 703, and a drain pipe 707 is fixedly connected to the side wall of the filter box 703.
