Patent ID: 7571867

Claim:
A showerhead with a turbocharger mechanism, the showerhead comprising: a showerhead housing, comprising a case and a water drainage panel, wherein the case has a case water inlet port for introducing a water flow, and a case wall that gradually expands; the water drainage panel has a water spray nozzle disposed thereon and is disposed at a most bottom end of the case and hermetically connected with the case; a turbo-compressor unit, accommodated in a housing chamber, wherein the turbo-compressor unit comprises: a compressor compartment, having a compressor compartment water inlet port communicated with the case water inlet port, so as to convert the water flow into a vortex flow to push a turbo-pump impeller, so that the water is discharged from a compressor compartment water exit; and the turbo-pump impeller, rotatably accommodated in the compressor compartment; a turbo-generator, provided in the housing chamber, and comprising a generator and a generator driven shaft coaxially connected to the turbo-pump impeller; wherein when the turbo-pump impeller is driven by the vortex flow, the turbo-pump impeller drives the generator driven shaft to rotate so that the turbo-generator generates electric energy; the compressor compartment water exit, in communication with the water spray nozzle disposed on the water drainage panel, so that the water flow is sprayed from the water spray nozzle; and an illumination means, accommodated in the housing chamber and electrically connected with the turbo-generator, so as to emit light beams, wherein the compressor compartment further comprises a compartment upper body, and a compartment lower lid detachably covered on a bottom of the compartment upper body, so as to define a compartment chamber therein to accommodate the turbo-pump impeller, wherein the compressor compartment water inlet port in communication with the case water inlet port is disposed on the compartment upper body; a centrifugal passage with a diameter of cross-section gradually reduced from the compressor compartment water inlet port to the compressor compartment water exit is disposed on the bottom of the compartment upper body, for guiding the water flow coming from the compressor compartment water inlet port, and the centrifugal passage comprises an inner wall on which a plurality of inclined intakes tangential to a moving direction of the water flow is disposed which allows a portion of the water flow to enter in a direction tangential to the rotation direction of the turbo-pump impeller, so that the intake water entering from the inclined intakes generate continuous tangential pressure along a circular centrifugal passage to generate the vortex flow; a compartment lower recess capable of accommodating the turbo-pump impeller is disposed at the bottom of the compartment lower lid, and the compressor compartment water exit is disposed at the bottom of the compartment lower recess.
