Abstract
This utility model relates to the field of atomizing spray gun technology, specifically to an atomizing oil spray gun. It includes: a spray gun body with a piston chamber and a vent hole connected to the piston chamber; a nozzle assembly mounted on one end of the spray gun body, including an oil outlet; a piston rod with the piston chamber opening away from the nozzle assembly; and an end cap mounted on the spray gun body at the opening of the piston chamber. An adjustment knob is threaded onto the end cap, comprising a knob body and a limiting rod. The limiting rod is located on the knob body, which is located outside the end cap. The end of the limiting rod extends into the piston chamber and faces the piston rod to limit its travel. A vent hole communicating with the piston chamber is provided on the end cap. A rotating cavity opening towards the end cap is provided on the knob body, rotatably fitted onto the end cap. The outer opening of the vent hole is located within the rotating cavity.
