Technical Field

The invention relates to the technical field of air guns, in particular to a centrifugal fan blade spray gun which is mainly applied to spraying operation and used for improving the pressure of the air gun and the atomization effect.

Background

The air gun is a common production processing tool, and the air gun corresponds to an ion air gun, a spraying air gun and the like according to different use functions. At present, spray guns in the market all use a first-stage fan blade air outlet mode, fan blades are placed on an air inlet side or an air outlet side, and compared with pneumatic spray guns, the pneumatic spray guns have the defects of small air pressure and small air volume. Therefore, a new air gun is needed to be designed for increasing the pressure of the spray gun and improving the atomization effect.
