Description

Technical Field

[0001] The utility model belongs to the technical field of spray gun atomizing nozzles, and particularly relates to a nozzle structure for improving the atomizing effect of a spray gun. Background Art

[0002] A spray gun is a tool for spraying paint. It uses compressed air to quickly release the paint as power to spray the paint out of the nozzle. Therefore, the design of the nozzle is particularly important for the spraying effect.

[0003] Existing nozzles usually spray the paint in atomized form through air holes. This method will reduce the atomization effect after spraying, resulting in uneven spraying, increasing the use of paint and generating more usage costs. Therefore, we propose a nozzle structure that improves the atomization effect of the spray gun. Utility Model Content

[0004] The purpose of the utility model is to provide a nozzle structure for improving the atomization effect of a spray gun, by arranging a striking leaf, specifically, the atomized paint is discharged through the discharge hole, and when it contacts the striking leaf, the striking leaf will be pushed and a striking effect will be produced. At the same time, the striking leaf drives the rotating shaft to rotate through the fixed plate, so that the striking leaf can strike the paint again to atomize it, thereby improving the atomization effect, making it more uniform during spraying, reducing the use of paint, and reducing costs. It solves the problem that the atomization effect of the existing atomizing nozzle will be reduced after the paint is sprayed out, thereby causing unevenness during spraying, and increasing the use of paint, resulting in more usage costs.

[0012] Furthermore, a threaded ring is fixedly connected to the left side of the spray gun joint, the threaded ring is threadedly connected to the hexagonal nut, and an air pipe joint is fixedly connected to the top of the spray gun joint.

[0013] Furthermore, the discharge hole and the opening are interconnected, the top of the connection block is fixedly connected to the inner wall of the rotating ring, and the inner wall of the rotating ring is in contact with the outer surface of the protrusion.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model sets a striking blade, specifically, the atomized paint is discharged through the discharge hole. When it contacts the striking blade, it will push the striking blade and produce a striking effect. At the same time, the striking blade drives the rotating shaft to rotate through the fixed plate, so that the striking blade can strike the paint into atomization again, thereby improving the atomization effect, making it more uniform during spraying, reducing the use of paint and reducing costs.
