Technical Field
The utility model relates to a spraying technical field especially relates to an atomizing spray gun.
Background
A paint spray gun is a tool for spraying paint, is used for surface treatment of products, and is one of coating equipment. The coating is sprayed on the surface of an object to be coated by using compressed air in a spray manner, and meanwhile, an air pressure device, such as a pressure tank, a pressure barrel, a pump and the like, is externally connected. Compared with the traditional manual painting, the paint spraying gun has the advantages of higher timeliness and more attractive appearance, the efficiency is 5-10 times higher than that of brushing, and the coating is fine, smooth and uniform.
According to the working principle, the current paint spray guns on the market are mainly divided into an updraft spray gun, a gravity spray gun and a pressure feed spray gun, and the updraft spray gun is most commonly used. The coating barrel of the updraught type spray gun is positioned below the nozzle, compressed air forms a low-pressure area when passing through the nozzle, and the coating in the barrel upwards enters the nozzle under the action of atmospheric pressure, is mixed with the compressed air in front of the spray gun and is blown, dispersed and atomized to be sprayed out. The advantages of good stability of spraying operation, convenient addition of paint to a paint tank or color change, larger paint capacity than a gravity type spray gun, and suitability for general spraying. However, such spray guns have some drawbacks: firstly, a small hole is formed in the upper surface of a nozzle head of a paint spraying gun, compressed air enters an atomizing cap through the small hole during operation to be mixed and then is sprayed out, and due to the fact that an air outlet is small and an internal gas loop is complex, insufficient atomization is easily caused, and a paint spraying operation surface cannot achieve a due effect; in addition, the nozzle head is compact in structure and not easy to clean and clean, the spray head is easy to block, more time is consumed for cleaning and cleaning, a new nozzle head needs to be replaced after the spray head is blocked, the efficiency is influenced, and waste is easily caused.
