Description

Technical Field

[0001] The present invention relates to the technical field of coating spraying, and more specifically to a green and environmentally friendly coating spraying device. Background Art

[0002] Paint spraying is a coating method in which paint is sprayed onto the surface of an object through a spraying device. The paint can be of various types, such as paint, coating, varnish, etc. The advantage of paint spraying is that the paint can be sprayed onto the surface of the object quickly and evenly, so that the coating has better adhesion and appearance effect. At the same time, paint spraying can save the amount of paint used and can achieve coating of various complex shapes. When spraying paint, you need to pay attention to safety issues to prevent paint splashing and poisoning.

[0003] During the use of the existing green and environmentally friendly paint spraying device, since the paint will automatically solidify after not being used for a period of time, the staff needs to indirectly add thinners to the paint to reduce the viscosity of the paint and maintain the fluidity of the paint. If the staff forgets to add thinners during the process, the paint will solidify and cannot be used, thereby causing the paint spraying work to be unable to proceed. Therefore, how to design a green and environmentally friendly paint spraying device that can automatically add thinners to the paint has become our current problem to be solved.
