Description

Technical Field

[0001] The utility model relates to a paint spray gun. Background Art

[0002] A spray gun is a common spraying equipment, which mainly atomizes the paint through the spray gun and then sprays the paint onto the surface of the workpiece, so that the processed surface can obtain a beautiful and uniform coating layer.

[0003] Due to defects in the structural design of the spray gun in the prior art, the slurry is sprayed onto the processed surface without being completely mixed, causing an orange peel phenomenon on the processed surface, which affects the aesthetics of the coating layer. Utility Model Content

[0004] The utility model aims to provide a technical solution for a paint spray gun in view of the deficiencies in the prior art, which can not only filter the particles in the slurry in the barrel to prevent the orange peel phenomenon after spraying caused by uneven mixing of the slurry, but also stir the filtered particles with the slurry to improve the spraying effect.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0016] Furthermore, the second cantilever is obliquely connected to the lower ring, and a cleaning strip is provided on the bottom surface of the second cantilever. The particles can be filtered through the filter net. During the rotation of the second cantilever, the cleaning strip can be driven to push the particles at the bottom, so that the particles are integrated into the slurry for stirring and mixing.
