Shower head with alternating outlet function

A shower head with alternating outlet function, wherein comprising:

• an inlet waterway, comprising an inlet port, an outlet port and an entire waterway therebetween;
• an outlet terminal, having at least two outlet cavities, the outlet cavities are rotatably distributed on a plane and being mutually independent, and the outlet cavities have outlet holes, alternating inlet holes and synchronous inlets;
• the outlet holes are disposed on an outlet surface of the shower head;
• and
• an alternating cavity with alternating inlets, fixed to the outlet terminal;
• the alternating cavity is connected to all alternating inlet holes;
• the interior thereof is disposed with a hydraulic alternating device to make the alternating inlets to connect to the alternating inlet holes in alternating manner driven by water pressure;
• the synchronous inlets and the alternating inlets are switched to connect to the outlet port by rotating a water diversion plate;
• the water diversion plate has a structure that when the alternating inlets are connected to the outlet port, the synchronous inlets are mutually separated and sealed,
• wherein the hydraulic alternating device comprising an impeller rotating by the impact of the flow-in water from the alternating inlets, the impeller is alternately coupled to the inlet holes of the outlet cavities by a speed reducer driving a water stop blade to rotate,
• the speed reducer including a planetary gear train,
• the planetary gear train including:
• a sun gear fixed to the central shaft of the impeller;
• three planetary gears engaged to the external periphery of the sun gear uniformly, rotation shafts of the three planetary gears disposed to the water stop blade, and
• a gear frame with an internal annular gear, engaged to the external peripheries of all gears,
• the gear frame fixed to the internal wall of the alternating cavity.
