Abstract
An automatic cleaning and spraying device includes a mixer connected in series with a gas pipeline of the spraying device. A cleaning liquid (such as a solvent) introduced by the mixer is guided to a controlled cleaning liquid valve installed at the front end of the cleaning liquid pipeline, so that the cleaning liquid can be mixed with a gas, and then the mixed liquid and gas flow towards a spray valve and an atomizer. During a normal spray operation, only the pressurized gas valve and spray valve are turned on for the actual spray operation. After a specific period of operation, the cleaning liquid valve may be controlled automatically to input the cleaning liquid to the mixer and then to the spray valve and atomizer in order to clean the surrounding and inner wall of the spray outlet and achieve the effect of cleaning the spraying device automatically.
