Abstract

A shower head structure includes a front cover disc, a water outlet disc, a joint base, a water stopper body and a water stopper. The shower head body is installed to the joint base, and the water stopper body is connected to the water outlet disc, and the water stopper is installed into the hollow hole of the water stopper body. When water flows into the shower head body, the water pressure pushes the water stopper and the water gasket to block the hollow hole and stop water coming out from outlet disc, but the water will come out from the periphery of the water stopper body instead. If an accessory is installed, the water stopper is pushed to interconnect a passage, so that the water will be supplied to the accessory from the middle of the front cover disc to produce a variety of splashes.

Claims

1. A shower head that can be used together with different accessories, comprising a shower head body, a front cover disc, a water outlet disc, a joint base, a water stopper body, a water stopper, and a spring coil;

wherein when said front cover disc and said water outlet disc are installed to said shower head body, a screw thread at the periphery of said water outlet disc is screwed with a screw thread at the periphery of said shower head body, and said water outlet disc includes a depressed hollow hole for coupling a joint base, a water stopper body, a water stopper, and a spring coil;

said shower head body includes an internal screw thread disposed at the internal periphery of an internal space and integrally coupled to an external screw thread of said joint base, and said internal screw thread is coupled to a ball joint;

said joint base includes a hollow passage disposed at a central position of said joint base, and said passage includes a flowing hole disposed at the periphery of said passage and interconnected with said internal space of said shower head body; and

said water stopper body is substantially a hollow hole and includes a water gasket having a diameter slightly smaller than said hollow hole and disposed at a position in a rear section, and the surface of said rear section is an external screw thread section, and two corresponding L-shape grooves are disposed in said front section;

said water stopper includes a plurality of guiding holes disposed on the circumferential surface of said water stopper and interconnected with said flowing hole, and said rear end has a protruded gasket;

said external screw thread section of said water stopper body is screwed with said internal screw thread at the rear end of said water outlet disc hollow hole, and said water stopper is installed in said hollow hole of said water stopper body, and said spring coil is installed and limited between said protruded gasket at the rear end of said water stopper and said passage of said joint base, such that when water flows into said shower head body, the pressure of water pushes said water stopper forward to be attached onto said water gasket at said hollow hole of said water stopper body to stop water from said front cover disc, but the water flows out from said flowing hole adjacent to said passage of said joint base passage into said internal space of said shower head body, and then the water flows out from the periphery of said front cover disc; and

if an accessory is installed to said shower head body, said water stopper is pushed to interconnect said passage, and said flowing hole adjacent to said passage of said joint base passage is blocked to stop water coming out from the periphery of said front cover disc, and the water is supplied to said accessory from the middle to produce a variety of splashes.

2. The shower head structure that can be used together with other accessories of claim 1, wherein said each accessory situated at said water stopper body of said water outlet disc is positioned by fixing a protruded latching section at the external surface of a sheathing base with said L-shape groove disposed at front section of said hollow hole of said water stopper body.
