A water pump is bolted into the tank via the support plate. A hose is connected to the top of the noise reduction chamber via a reserved hole, and a spray gun is connected to the other end of the hose. An exhaust fan is bolted to the top of the noise reduction chamber, and a purification box is connected to one side of the exhaust fan via a pipe. An activated carbon filter is bolted into the purification box. This utility model has excellent spraying effects and a purification function, making it suitable for widespread promotion and use. In the process of realizing the present utility model, the inventors found that the existing technology had the following problems: 1. After the spray device finishes working, the residual material in the tank needs to be stirred and cleaned and poured out, which cannot achieve the purpose of convenient use; 2. The traditional spray device has too single usage method and cannot meet the needs of current engineering construction. It is impossible to complete various types of on-site engineering construction work with only a single spray gun. Utility Model Content
