[0002] Wall spraying is one of the common decoration methods in the decoration project. Spraying the wall can make the wall smoother and flatter, and at the same time improve the wall's alkali resistance. In the process of spraying the wall, a spraying device is needed to spray the inner wall. When the paint is sprayed, the impact force of the paint often causes the paint to splash everywhere, causing pollution to the surrounding environment. Therefore, protective devices are usually used to prevent paint from splashing.
