[0027] 2. With the help of a water pump, the water is pumped into the circulation water pipe, so that the water flows out from the water outlet, and then collected in the protection box, and then filtered through the filter plate and the water inlet, so as to collect the paint in the water, thereby capturing and fixing the paint mist and fine particles in the air, reducing pollutants in the air, which not only protects the health of the operators, but also reduces the impact on the working environment, making the working area cleaner and safer. By reducing the paint particles in the air, the interference of these particles on the spraying surface is reduced, which helps to ensure the consistency and uniformity of the spray coating, reduces the color difference and uneven spraying caused by the diffusion of paint in the air, and improves the spraying quality. These splashed paints will not fall on the ground or other surfaces, but will be collected by the water in the water curtain, thereby reducing the waste of paint and increasing the recycling rate of paint.
