Abstract

The present invention of a self-generating lighting shower head comprises a top hood, an upper holder, an inlet header, a revolving part, a lower holder, an electric module, a shade unit, and a shower head disc unit: the upper holder is held in the top hood; the inlet header is installed in the water bearing space; the revolving part with a number of rotary vanes is placed in the inlet header and rotates under rush of water flows via water inlets; the lower holder has a watertight cavity at bottom to accommodate the electric module; the electric module comprises a spindle pivoted to and driven by the revolving part for generation of electric energy transformed from dynamic energy and luminescence excited by a number of luminous components on a printed circuit board. As such, the present invention is capable of generating electricity supplied to luminous components for illumination during a shower.

Claims

1. A self-generating lighting shower head, comprising:

A top hood with a through hole;

An upper holder held inside said top hood and comprising a joint part at top and a water bearing space at bottom;

said joint part which protrudes from said through hole on said top hood and links an outlet hose of a bathroom comprises a clearance hole leading to said water bearing space to which water flows from said outlet hose is conveyed;

An inlet header held in said upper holder'"'"'s water bearing space and comprising (a) a water feeding space centrally and downward and (b) a number of water inlets arranged circumferentially and leading to said water feeding space, both of which allow ater originally held in said upper holder'"'"'s water bearing space to pass through and run downward;

A revolving part comprising a core hole centrally and a number of radial rotary vanes circumferentially which are held in said water feeding space of said inlet header and rotate under rush of water flows;

A lower holder, a component slightly smaller than said water bearing space of said upper holder, comprising (a) an assembly-related core hole at top which is located under said water bearing space of said upper holder for development of an appropriate gap, (b) a watertight cavity under said core hole, and a number of discharge orifices on circumference of said watertight cavity through which downward water flows out of said inlet header'"'"'s water feeding space pass through said gap between said lower holder and said upper holder and run outward;

An electric module provided with a spindle, a protective shell, a printed circuit board and a number of luminous components on said printed circuit board and held in said watertight cavity of said lower holder;

said spindle protruding from said watertight cavity is pivoted to said core hole of said revolving part and synchronously driven by said revolving part for output of electric energy transformed from dynamic energy because of rush of external water flows;

A shade unit comprising a shade, a first washer, and a bolt-on disc, all of which are assembled with female threads on said bolt-on disc screwed onto male threads at a lower end of said lower holder;

A shower head disc unit installed at said upper holder'"'"'s bottom and comprising a center hole aligning said lower holder'"'"'s watertight cavity, separating luminous components from water, and surrounded by a plurality of nozzles through which water flows passing through said gap between said lower holder and said upper holder are sprayed downward.

2. The self-generating lighting shower head according to claim 1 wherein said shower head disc unit consists of a disc-shaped upper cap, a middle cap, and a lower cap, each of which has a center hole:

said upper cap comprises a plurality of axial stubs raised downward, each of which is deployed around its center hole and has a nozzle centrally;

said middle cap (lower cap) comprises round orifices deployed around its center hole and penetrated by said upper cap'"'"'s axial stubs to be exposed outside.

3. The self-generating lighting shower head according to claim 1 wherein said upper holder comprises a length of male threads at its joint part:

said joint part allows its clearance hole to be passed through by an adapter for completion of an assembly based on a procedure as follows, (a) a spheroid part of said adapter is held in a second washer, (b) a nut is screwed onto said male threads of said joint part, and (c) said adapter'"'"'s core hole is coupled with an outlet hose of a bathroom for conveying external water into said the present invention of a shower head.
