When the existing spraying equipment is in use, there are problems such as paint precipitation, which affects the spraying quality. Chinese Patent CN218774998U discloses a surface treatment device for civil air defense doors, belonging to the technical field of surface spraying of civil air defense doors. It includes a paint tank and a spraying gun. A supply mechanism is arranged in the paint tank. The output end of the supply mechanism is connected to the spraying gun through a connecting pipe. The supply mechanism is used to draw the paint in the paint tank to flow into the spraying gun. During the flowing process, the paint at each height in the paint tank flows into the spraying gun simultaneously. Therefore, the concentration of the paint flowing into the spraying gun remains constant, and the difference is small. A fan blade is arranged in the spraying gun. The fan blade rotates under the impact of the paint flow and stirs the paint, so that the components in the paint in the spraying gun are mixed evenly before spraying, achieving the purpose of uniform distribution of the components in the paint sprayed out through the spraying head, and further improving the spraying quality.

[0003] The following deficiencies exist in the above prior art: when the piston in the prior art continuously descends, the number of liquid discharge holes on the liquid discharge pipe in contact with the paint will also continuously decrease. As a result, it is easy to cause a decrease in the speed of the paint entering the interior of the liquid discharge pipe, affecting uniform spraying; and when the paint is ejected from the spraying head, the paint spray will splash around, so it is easy to be inhaled by the staff. Therefore, a spraying device for surface treatment of civil air defense doors is provided to solve the above problems. Content of the Utility Model
