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 such that both the left clipping rod and the right clipping rod of the frame member in the injected mold being propped by a propping member to open outward, and forms an integrally wrapped nozzle. After the propping member in the mold retracts and separates from the mold, the contraction of the elasticity for the two clipping rods of the supporting frame member made of hard plastic material gives an excellent anti-leaking effect for the crevices at the center of the nozzle.

Claims

1. An integral soft and hard plastic nozzle structure, comprising:

a supporting frame, made by injection of hard plastic material, at least having a complete frame and two clipping rods, and a penetrating hole being disposed at the center of the frame, and the two clipping rods having a bent inclined pressing section on each end of the clipping rod;

a soft leather layer, made of hard plastic material, wrapping the supporting frame to form the supporting frame by injection, and a water outlet crevice being disposed in the middle of the front end of the supporting frame;

by means of the supporting frame being placed in the mold, and a propping mold passing through a penetrating hole at the center of the supporting frame, such that the propping mold props again the inclined pressing section at the end of the clipping rod and the clipping rod being squeezed to open up in a tiny angle and forms by injection an integral wrapped supporting frame having the soft leather layer on its exterior.

2. An integral soft and hard plastic nozzle structure as claimed in claim 1, wherein said supporting frame having a positioning pillar protruded from the outer side of the clipping rod.
