An improved sprinkler head for use on a sprinkler gun in connection to garden hose having a sprinkling cap, a bottom board and a base is removably secured to a sprinkler gun. The bottom board having a number of holes defined on the periphery of a circle is secured to the sprinkling cap by ultrasonic welding art. The sprinkling cap has a number of discharge openings defined in correspondence to the holes of the bottom board. The base having a discharge outlet, and the sprinkling cap along with the bottom board are fixed together by a screw. The discharge openings of the sprinkling cap have a tubular extension respectively and the extensions are bridged by a continual wall so as to define a closed area. A ring area having a plurality of tiny pores disposed adjacent the circularly located discharge openings corresponds to the outer side of the wall-closed area and a small ring of tiny pores disposed at the center of the sprinkling cap corresponds to the inner side of the wall-closed area so that when the sprinkling cap is selectively rotated to make the discharge outlet register with one of the discharge openings of the sprinkling cap water can be delivered in different manners.
