Abstract

A lubricant atomizing device for a grease gun involves refined spray-on grease for the external surfaces of large mechanical components, and includes an oil discharge tube and a refinement tube nozzle connected to the front end of the main body. An air pressure source is connected to the main body. A flow diverter switch is installed on the main body that divides the air pressure source into two streams. One air pressure flows into the main body to drive a piston chamber to pressurize and squeeze out the grease, while the other air pressure flows through a flexible tube into the refinement tube nozzle. Through the reduction in hole diameter to accelerate air flow, and under the dual action of pressurizing the piston chamber and accelerating the refinement of grease through air flow, the grease gun can smoothly and uniformly spray out refined grease.
