[0003] From the filtering function, some traditional washing devices do not even have an effective filtering system. This makes it impossible to intercept the particulate impurities carried in the water during the washing process. When the water flow washes the surface of the workpiece, these impurities will rub against the surface of the workpiece with the water flow. For example, in the coating pre-treatment of automobile parts, if the metal debris, sand particles and other impurities in the water are not filtered, they are likely to scratch the coated surface during the washing process, resulting in scratches, pits and other defects on the surface of the workpiece.
