AI Technical Summary
After the spraying operation is completed, the mixed liquid in the pipeline of the existing spraying equipment is prone to backflow, which leads to environmental pollution and corrosion of the spraying equipment components.
A spraying device is designed, comprising a liquid container, a first pipeline assembly, a second pipeline assembly, a nozzle, a first valve assembly, and a second valve assembly. The first valve assembly controls the opening or closing of the pipeline, and the second valve assembly automatically closes when the first valve assembly is closed to prevent liquid backflow.
It effectively prevents backflow of mixed liquids, avoids environmental pollution and corrosion of spraying equipment components, and extends the service life of the equipment.
