AI Technical Summary
Technical Problem
The existing spray gun valve structure lacks air intake, resulting in unstable spray paint and poor atomization effect, affecting the product surface quality.
Method used
By expanding the intake passage at the sealing of the valve sleeve and the valve needle cone surface, the intake of compressed air is increased, the fluorinated rubber sealing ring is used to improve the sealing and service life, and material saving and processing links are saved through integrated molding.
Benefits of technology
It significantly increases the air intake of the paint gun, improves the spraying effect, extends the service life of the sealing ring, reduces production costs, and improves the stability and service life of the product.

Abstract
The utility model relates to the field of valves of paint spraying guns, in particular to an efficient air inlet valve device which is installed in a paint spraying gun and comprises a valve sleeve. A valve needle is arranged in the valve sleeve; the valve needle comprises a cone frustum, and the cone frustum abuts against the valve sleeve. And an air inlet channel is expanded at the conical surface sealing part of the valve sleeve and the valve needle, so that the air inlet amount of compressed air is increased, and an excellent spraying effect is obtained.
