Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic powder spray guns, and particularly relates to a modularly assembled manual electrostatic powder spray gun. Background Art

[0002] An electrostatic powder spray gun is mainly a spraying tool for surface painting, mainly applied to metal surface painting. The working principle of the electrostatic powder spray gun is as follows: under the blowing of an auxiliary air flow, powder coating particles are ejected from the nozzle of the gun head in an atomized state. There is an electrode needle at the center of the nozzle that can release high-voltage static electricity. The electrode needle can radiate an electrostatic field. When the atomized powder coating particles pass through the high-voltage electrostatic field, the powder will be charged with static electricity, and finally the powder coating particles will be adsorbed on the surface of the workpiece to be sprayed with opposite static electricity. This spraying process is an electrostatic spraying process.

[0003] However, the existing manual electrostatic powder spray guns are troublesome to assemble and not convenient for subsequent maintenance after assembly. For example, the Chinese patent publication number: CN217491283U discloses a powder electrostatic spray gun, whose gun body is assembled by separately manufacturing a gun body 11, a handle 12, an arched dome 112 and a rear cover 3. Since there are many assembled shells, the assembly is troublesome. In addition, it is not convenient for subsequent disassembly and repair after assembly, which is extremely troublesome, and there are many mold parting lines on the appearance of the gun body, which reduces the aesthetics of the powder spray gun to a certain extent.
