A spray gun head includes, a diverter bushing, a nozzle body, an air cap and a locking ring. First and second vent holes are separately provided in the spray gun head. The diverter bushing is provided with a plurality of jets disposed in relation to the first vent hole to form a first air port. The nozzle body is provided with an airflow guide ring having airflow guide holes disposed relative to the inner wall of the diverter bushing to form a second air port. A plurality of first jets and second jets are provided in the air cap which guards the nozzle body. Air from the first and the second vent holes flows-through the first air port, the second air port air, the diverter bushing and the airflow holes in the airflow guide ring to be respectively ejected from both air jets.
