Description

Technical Field

[0001] The invention relates to the technical field of pneumatic spray guns, in particular to an energy-saving, environment-friendly and multifunctional double-head pneumatic spray gun. Background Art

[0002] The working principle of a pneumatic spray gun is to control the flow and spraying of paint by pushing a piston or valve with compressed air. When the air supply is turned on, compressed air enters the pneumatic spray gun and pushes the piston or valve inside. This action causes the paint to be released into the nozzle, and at the same time, a high-speed airflow is generated by compressed air, which atomizes the paint into tiny particles and sprays them onto the surface of the target object.

[0003] When a double-head pneumatic spray gun is in use, paint is sprayed out from two channels at the same time to achieve mixed spraying of two groups of paint. This design not only improves the spraying efficiency, but also reduces the energy consumption caused by paint waste. However, there are many potential safety hazards in the spraying operation, such as high-pressure gas leakage, misoperation of the spray gun, etc. Especially when used in factories, pneumatic spray guns are easily impacted by the outside world, making the spray gun easily damaged.
