Disclosed herein is an automatic cleaning apparatus for paint sprayer gun comprising a solvent cleaning tank, cleaning tank, and a check valve. The solvent cleaning tank has a pressurized air inlet, the cleaning tank has a plurality of vertically erected first tubes equipped with at least one nozzle for each tube, a second tube is connected with each first tube to communicate all first tubes one another, and a third tube is used to communicate the air inlet and the solvent cleaning tank and cause the solvent to be ejected from the nozzles. The check valve is for collecting the solvent in the bottom of the solvent tank. With this structure, the cleaning apparatus of the present invention uses compressed air as its power source so as to eliminate hazardous electrostatic induction owing to mechanical friction caused by rotation of apparatus components during the cleaning operation. The present invention has noticeable advantages of low noise, simple structure, high security, prolonged lifetime, high flexibility and low production cost.
