This invention relates to an improved pressure regulation structure at the tip of the spray gun connected to the nozzle. A screw hole is formed in the front section of a passage where a regulation shaft extends from the tip of the spray gun. An inner recess and an outer recess are formed on the front surface of the spray gun respectively with an air outlet. A gasket with slots is inserted between the spray gun and the nozzle. A hollow screwed tube formed in the rear of the nozzle to receive insertion of the gasket before being engaged to the screw hole of the spray gun. An inner recess and an outer recess with air ventilating holes and air outlets formed in the nozzle. A groove is formed around a nozzle tip at the front side of the nozzle. The inner and outer recesses of the nozzle abutted to the inner and outer recesses of the spray gun to form a pressure regulation air port; and outer threads provided on the nozzle to receive a nut for the spray head connected to a nut to hold against the nozzle.
