Abstract

A shower head with alternating outlet function, includes: an inlet waterway with an inlet port, an outlet port, a waterway, an outlet terminal having at least two mutually independent outlet cavities rotatably distributed on a plane, and all have outlet holes, alternating inlet holes and synchronous inlets; the outlet holes are disposed on the 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 a water diversion plate.

First claim

The invention claimed is:

1. 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.

2. The shower head with alternating outlet function according to claim 1 , wherein the water diversion plate is rotatably coupled to the outlet port.

3. The shower head with alternating outlet function according to claim 2 , wherein the synchronous inlets and the alternating inlets are located on an top surface of the water diversion plate, the top surface is slidably coupled to the outlet port.

4. The shower head with alternating outlet function according to claim 2 , wherein the synchronous inlets and the alternating inlets are distributed on a same revolution surface in circumference, the synchronous inlet, the alternating inlets and the outlet port are rotatably symmetrical about the rotation axis of the outlet port.

5. The shower head with alternating outlet function according to claim 2 , wherein the outlet cavities are rotatably symmetrical; the alternating cavity, the water diversion plate and the outlet cavities are coaxial.

6. The shower head with alternating outlet function according to claim 5 , wherein the alternating inlet holes of the outlet cavities are centered on the central shaft thereof; the synchronous inlets of the outlet cavities are distributed in the external periphery of the alternating inlet holes in circumference.

7. The shower head with alternating outlet function according to claim 6 , wherein comprising two outlet cavities, the synchronous inlets thereof are distributed in the external periphery of the alternating inlet holes in circumference, two outlet areas correspondingly disposed.

8. The shower head with alternating outlet function according to claim 6 , wherein comprising three outlet cavities, the synchronous inlets thereof are distributed in the external periphery of the alternating inlet holes in circumference, three outlet areas are correspondingly disposed.

9. The shower head with alternating outlet function according to claim 6 , wherein comprising four outlet cavities, the synchronous inlets thereof are distributed in the external periphery of the alternating inlet holes in circumference, four outlet areas are correspondingly disposed.
