Rotary-sprinkling shower

A rotary-sprinkling shower, comprising:

• a body, which has a water inlet end and a water outlet end forming a waterway there-between;
• a front cover component rotatably disposed on the water outlet end of the body, equipped with water spray nozzles in communication with the waterway;
• a hydraulic driving unit disposed in the waterway, while connected with the front cover component by a rotating shaft, said rotating shaft is connected with said hydraulic driving unit by a deceleration mechanism,
• wherein:
• the hydraulic driving unit is driven by water flow in the waterway to drive the front cover component to rotate;
• said hydraulic driving unit comprises an inclined water body and an impeller, an inclined hole is disposed on said inclined water body and can generate an inclined water stream to drive the impeller to rotate, said deceleration mechanism comprises a planet gear, an outer gear ring and a connecting plate;
• said impeller, outer gear ring and the connecting plate have a same central line, there is an eccentric cam disposed on said impeller which acts as a planet carrier, such that said eccentric cam, said planet gear and the outer gear ring form a planetary gear train, wherein said eccentric cam is the rotation center of said planet gear, the central line of the outer gear ring is the revolution center of said planet gear, said planet gear is meshed with said outer gear ring;
• there is a transmission rod eccentrically disposed on said planet gear, and a transmission hole is disposed on said connecting plate, the rotation of the planet gear drives said connecting plate to rotate with the cooperation of said transmission rod and the transmission hole, said transmission hole is bigger than the cross-section of the transmission rod such that a movement room is formed, said movement room can allow said transmission rod to revolve around the planet gear;
• and
• the rotating shaft of said front cover component is fixedly connected with said connecting plate.
