When the nozzle is used, the inner air duct 10 continuously blows to the tail end of the round table II15, and the phenomenon that the outlet end of the medium channel 9 is blocked and the use is influenced due to the fact that the medium is gathered and sintered at the tail end of the round table II15 is prevented. The outer air duct 11 is continuously blown to the chamfer 7, so that the medium is prevented from being accumulated and sintered at the position, the through hole 8 is blocked, and the use is not influenced.

The on-off of a compressed air channel which is butted with the inner air channel 10 and the outer air channel 11 on the equipment can be separately controlled, when the nozzle stops spraying the medium, the equipment stops conveying the medium and stops introducing the compressed air into the inner air channel 10, but the compressed air is still conveyed to the outer air channel 11, the compressed air conveyed by the outer air channel 11 is continuously blown to the chamfer 7, and foreign matters are prevented from entering the nozzle; if the nozzle is not used for a long time, the outer air duct 11 can be closed at the same time, and tools such as a cover can be used for covering the right end of the nozzle to prevent foreign matters from entering.
