Abstract: A water spray gun having an improved sprinkler head structure for use on a garden hose. The sprinkler head has a head body and a sprinkling cap and a bottom plate that are joined together by way of ultrasonic welding art. The sprinkling cap is rotatably mounted onto the head body having a water outlet. The sprinkling cap has a peripherally ring area having a plurality of sprinkling pores and a number of water discharge holes of various geometric shapes. Each water discharge hole of the sprinkling cap has a tubular extension and the tubular extensions are bridged by vertical wall sections and an S-shaped wall section to define a closed area. The bottom plate has a plurality of circular holes ending with protruded flanges that defines a closed area in correspondence to that of the sprinkling cap.

Abstract: 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.

Abstract: A sprinkling seat structure for a lawn, including a circular frame seat, a connecting disk and a sprinkling rotary cover. The circular frame seat includes a circular peripheral frame and a central water-outgoing seat connected with the peripheral frame by several radial connecting ribs. A connector is disposed on one side of the water-outgoing seat for connecting with a water-incoming tube. The water-outgoing seat is formed with a water-outgoing opening for communicating with the connector. The connecting disk is formed with a central hollow downward projecting fixing boss. A free end of the fixing boss is formed with an inclined face having an annular groove. Several circular holes are formed around the fixing boss. The sprinkling rotary cover has a central sprinkling dome formed with multiple sprinkling meshes. Multiple sprinkling holes with various patterns and two opposite close holes are disposed around the sprinkling dome.

Abstract: A rotary head structure of a lawn sprinkling seat, including a base seat, a sprinkling head and a T-shaped locking body. The base seat is formed with a central water-outgoing connector. The sprinkling head has three radially extending water-outgoing passages spaced by equal angle and an insertion post on bottom face for fitting into the locking body which is screwed into the water-outgoing connector of the base seat. The water is conducted from the base seat to the sprinkling head to flow out from the water-outgoing passages thereof. A free end of each water-outgoing passage is formed with a large diameter hole having a conic peripheral wall for receiving a valve post of a hollow ball valve. The valve post of the ball valve is first passed through a tapered opening of a cylindrical valve sleeve and then fitted into the large diameter hole of the water-outgoing passage and fused therewith by ultrasonic wave.

Abstract: An improved water regulating cap mounted in combination to a sprinkler gun is provided with a soft guard cover at the front end thereof and a rubber friction cover at the rear end thereof so as to protect the regulating cap from damage in one aspect and to facilitate the operation thereof in another aspect. The soft guard cover and the rubber friction cover can also be integrally formed and removably mounted to the regulating cap readily.

Abstract: An improved sprinkler head having a top discharge cover and a water distributor plate which are integrally fixed together is rotatably mounted to a lever controlled nozzle for use in gardening or car wash. The top discharge cover has a first ring portion and a second ring portion concentrically disposed and having a plurality of fine meshes defined thereon. The top discharge cover having a number of discharge openings besides the concentric first and second ring portions is provided with a closed area which is sealedly surrounded with a section of the boundary defined in an S shape and the first ring portion is located inside and the second ring portion located outside of the closed area.
