ABSTRACT:
A drying gun includes a chamber and a handle made integrated with the body of the gun, an arc diverter being disposed between an inner end of a rear hole inside the chamber and an exhaust hole; a plug being placed in the rear hole in the chamber; a narrow exhaust gap being defined between a front surface of the plug and the inner end of the rear hole; a front tapered hole inside the plug being disposed corresponding to the arc diverter; the compressed air admitted through the exhaust gap being first guided by the arc diverter to follow the arc to change its direction into the exhaust hole thus to produce siphon effect; and the body of the drying gun may be combined with diffusers in different configurations.
