Abstract

A hard and soft plastic integral nozzle structure includes a built-in supporting frame member which is made of hard plastic, and at least having a left and a right clipping rod. A soft nozzle is formed integrally by inrection to wrap the the left and right clipping rods with a soft plastic. A taper board and a peripheral groove are provded in the center of the nozzle. The elasticity of the two clipping rods of the supporting frame made of hard plastic material brings an excellent anti-leaking effect for the water outlet crevice(s) at the center of the nozzles as well as a fully open status thereof.

Claims

1. An improvement of an integrally formed nozzle structure with soft and hard plastic, comprising:

a supporting frame made by injection of hard plastic material, at least having a complete frame and two clipping rods, wherein a opening is provided in the center of the frame; and

a coating layer made of soft plastic material, which is made by injection to wrap the supporting frame, and a water outlet crevice being disposed in the middle of the front end of the supporting frame, characterized in that;

a threaded fastening ring is provided in the end of the supporing frame, in order to hold the water outlet;

a taper board and a peripheral groove are provded in the center of the nozzle;

the elasticity of the two clipping rods of the supporting frame made of hard plastic material brings an excellent anti-leaking effect for the water outlet crevice(s) at the center of the nozzle, as well as a fully open status thereof.

2. The improvement of an integrally formed nozzle structure with soft and hard plastic according to claim 1, wherein the taper board is composed by the left and right lips on the two sides of the water outlet crevice, the border of the two lips is a thin board of the peripheral groove;

when the nozzle is being pressed, said border of lips transform and extend laterally

3. The improvement of an integrally formed nozzle structure with soft and hard plastic according to claim 1, wherein the taper board may be provided with two water outlet crevices.
