The plurality of bristles 22 are arranged in an annular shape and at equal intervals on the outside of the inner net 19. The end of the bristles 22 away from the inner net 19 is released from the outer net 18 to facilitate subsequent brushing of the surface of the outer net 18. The plurality of air jet nozzles 24 are located between the outer net 18 and the inner net 19. The recoil component is installed between the mounting ring 14 and the plurality of air jet nozzles 24.
