Patent ID: 8915455

Claim:
A massage shower that can achieve the dynamic switch of the water flow, wherein it comprises: a hollow essential body, which has an entry end and an effluent end; a water power driver element, it comprises a oblique water body and a impeller that has a center hole under the oblique water body, and the oblique water body is set at the effluent end of the said essential body, several oblique holes that form oblique water flow and drive the impeller to rotate are distributed on the oblique water body; a moving plate, which has a center hole and at least one water-division hole; and a face cover component, which comprises an upper cover and a face cover, the upper periphery of the said upper cover is fixed to the periphery of the said oblique water body, and said upper cover and the said oblique water body form a cavity together, and an upper shaft base is set in the center position of the bottom surface of the said oblique water body, and a lower shaft base is set in the center position of the inner bottom surface of the said upper cover, a rotation shaft which passes through the center hole of the impeller and the center hole of the moving plate in sequence from top to bottom is set between the said lower shaft base and the said upper shaft base; there are at least two independent cavities between the upper cover and the face cover, and at least one effluent hole is set on the inner bottom surface of the upper cover corresponding to each said independent cavity, and the said effluent holes are all set at the position corresponding to the said water-division hole; several water injection nozzles that connect to every independent cavity respectively are distributed on the said face cover; wherein: the said moving plate rotates with respect to the inner bottom surface of the upper cover, so that its water-division hole is connected to different effluent holes or the combination of the effluent holes; the impeller and the moving plate are connected through a differential gearing transmission retarding mechanism; and said differential gearing transmission retarding mechanism comprises a eccentric wheel formed by the downward extending of the hole periphery of the impeller, an external gear with a center hole and a annular gear formed by the surround wall of the upper cover, the external gear is sleeved around the outboard of the said eccentric wheel through its center hole and engaged with the annular gear by small teeth difference.
