ABSTRACT:
A siphon type of drying gun includes an arc diverter disposed between an inner end surface in an accommodation space in a body of the gun and a flared hole. A rear cover having a flange is screwed into the body. An exhaustion gap is defined between the flange of the rear cover and the arc diverter. A front tapered hole in the rear cover corresponding to the arc diverter to guide the compressed air admitted into the exhaustion gap to flow by following the arc diverter and taking a turn into the flared hole so to produce siphon effects against ambient air to reduce noise level.
