Description

Technical Field

[0001] The utility model relates to the technical field of spray guns, in particular to a simple high-viscosity waste liquid spray gun. Background Art

[0002] Spray guns also include pressure spray guns, Carle spray guns, and automatic recovery spray guns. Spray guns can be used directly with paint in the industry, that is, simple spray guns can be installed in automated equipment, such as glue guns, waste liquid spray guns, coating guns and other spraying equipment. When the spray gun is processed, the sprayed paint or waste liquid will come into contact with objects, which can easily cause paint or waste liquid splashing.

[0003] Currently, most existing waste liquid spray guns use Hastelloy gun heads, and compressed air is used to atomize the waste liquid in the atomization chamber to achieve a spraying effect. However, this spray gun is not suitable for high-viscosity material disposal, and a stable flow rate cannot be guaranteed for high-viscosity waste liquid, resulting in injection blockage and uneven atomization field. Therefore, it is necessary to design a simple high-viscosity waste liquid spray gun to achieve the effect of efficient cooling of the spray gun, and the existing waste liquid spray gun does not have a good cooling function.
