Abstract

A water sprayer long tube and water pipe connector, having formed along a bottom section internal threads that are followed in respective order from its water inlet end by a first polytetrafluoroethylene water sealing ring, a ball valve, and a second polytetrafluoroethylene water sealing ring for coupling the two components. The opening of the water outlet end is of a smaller inner diameter than that of the opening at the water inlet end and a water sealing ring is ensconced along the inner diameter edge of the water outlet end. A flange formed at the bottom end of the long tube in the water inlet end of the connector is secured and constrained inside the connector, with the constraining of the long tube flange of the water sprayer enabling it to become assembled with the connector into a single structural entity that cannot be disconnected. Thus, after the water sprayer bottom end is assembled to the connector and when the connector bottom end is assembled to the water pipe connector, in addition to allowing the user to easily adjust the angle of the water sprayer, the separation and loss of the entire connector from the long tube of the water sprayer is effectively prevented.

Claims

1. A water sprayer comprising:

a) an elongated tube having a water spray head on a first end and an outwardly extending flange on a second end;

b) a connector having an inlet opening and an outlet opening wherein the outlet opening has a diameter smaller than a diameter of the inlet opening, the elongated tube passing through the outlet opening such that the outwardly extending flange contacts a portion of the connector so as to prevent removal of the connector from the elongated tube, the inlet opening of the connector having a threaded portion for connection to a water pipe;

c) first and second spaced apart, water sealing rings located within the connector; and

,

d) a ball valve located between the first and second water sealing rings, the ball valve being movable so as to control water flow through the connector.

2. The water sprayer of claim 1 wherein the first and second water sealing rings are made of polytetrafluoroethylene material.
