Description

Spray gun capable of preventing coating from leaking and splashing

Technical Field

The utility model belongs to coating spraying device especially relates to a prevent that coating from leaking spray gun of splash.

Background

The spraying is a device which disperses the coating into uniform and fine fog drops by a spray gun by means of air pressure and applies the fog drops on the surface of an object to be sprayed, a large amount of paint fog or splash can be generated during spraying, the object to be sprayed with an irregular shape, particularly an object with a strip-shaped structure, only a small part of atomized coating is sprayed on a target object because the nozzle of the spray gun is sprayed into a circle, most of the coating is dispersed in the air, and under some construction environments, the waste rate of the coating can even reach 90%, so that the coating is greatly wasted.

Disclosure of Invention

The utility model aims at overcoming the defects of the prior art and providing a spray gun for preventing coating from leaking and splashing.

The utility model discloses a prevent spray gun of coating leakage splash, by the body of a gun, the stock, the body of a gun spray tube, high-pressurepipe, air feed channel, the pressure regulating trigger, high pressure atomizing efflux pipe, atomizing nozzle and medium storage tank constitute, the outside bottom of stock is connected with high-pressurepipe, inside is equipped with air feed channel and high-pressurepipe intercommunication, air feed channel upper end and the inside high pressure atomizing efflux pipe rear end intercommunication of body of a gun, high pressure atomizing efflux pipe middle part is arranged in the body of a gun outside and is equipped with the air throttle by the pressure regulating trigger linkage on it, the front end is placed in the inside of body of a gun spray tube and is inserted the siphon of medium storage tank at its vertical intercommunication, the end of high pressure atomizing efflux pipe is equipped with atomizing nozzle, the end fixed connection of body of a gun spray tube atomizing nozzle prevents that the medium leaks the splash recovery cover, lower part connection honeycomb duct to medium storage tank preventing the medium leakage splash recovery.

As a further improvement of the utility model, the anti-leakage splash recovery cover is funnel-shaped, and the necking end and the atomizing nozzle are connected to the gun body spray pipe coaxially, and the edge of the necking end has an inner convergent liquid collecting edge.

As a further improvement, the caliber of the liquid collection edge of the neck-expanding end of the anti-medium leakage splashing recovery cover is smaller than the maximum caliber of the anti-medium leakage splashing recovery cover, and the neck-expanding end of the anti-medium leakage splashing recovery cover is a collection backflow storage tank for the leakage splashing liquid.

The utility model discloses a spray gun structural design who prevents coating and leak splash is reasonable, and droplet spraying scope is in a fixed interval when coating blowout, can not surpass the external portion of cover, and the target thing of application that can be more accurate, to a great extent has reduced the diffusion of coating in the air to can retrieve not by atomizing coating, can practice thrift the material.
