Abstract

An improved dispenser head structure for a garden watering sprinkler is integrally combined with a base plate by ultrasonic welding. The dispenser head is secured to the head portion of a sprinkler gun by a screw. The dispenser head is provided with a plurality of radially distributed full discharge openings on the periphery thereof. The dispenser head has a round board on which are equipped with 4 discharge outlets at the central area thereof. A ring area disposed adjacent to those peripherally located full discharge openings is provided with a plurality of bores. A round area is disposed at the center area circled by the 4 discharge outlets. There are a small C-shaped partition wall area and a large C-shaped partition wall area on the rear side of the round board, that are continually connected to the tubular extension of the 4 discharge outlets by vertical walls so that a closed area is defined at the center thereof. There are 6 inlet holes and 4 full discharge outlets on the base plate. The 6 inlet holes are registered with the 4 tubular extensions and the small and large C-shaped partition wall areas. Water can be filled up the closed area via the large C-shaped partition wall area and discharged via the multiple full discharge openings when the dispenser head is rotated to make the large C-shaped partition wall area selectively registered with a water discharge hole. Such a dispenser head permit a reverse flow of water externally jetted against the dispenser head to clean dirt accumulated in the dispenser head. The removed dirt can be brought out of dispenser head via the full discharge openings.
