Abstract

A water jet device for rotary massage includes a seat providing an outlet and a cavity; a cover providing an inlet; a separating member, a rotary shaft, an impeller and a rotor received in the cavity; at least one inclined water ejection port disposed on the separating member and communicating with the inlet; the impeller is mounted between the rotor and the separating member; the rotor is in the outlet, a plurality of curved grooves are formed on the periphery of the rotor; a track assembly includes an annular rail having ascending and descending sections formed on an inner bottom of the seat, and sliders formed on an underside of the impeller; water flowing through the water ejection port rotates the impeller, further drives the rotor to rotate, and the fluctuation of the impeller and the rotor drives the water fluctuates, thus form intermittent and dynamic annular water sprays.

First claim

What is claimed is:

1. A water jet device for rotary massage, comprising:
a seat ( 1 ) including at least one outlet ( 10 ) and a cavity ( 11 );
a cover ( 2 ) including an inlet ( 20 );
a separating member ( 3 ) including at least one inclined water ejection port ( 30 ) communicating with the inlet ( 20 );
a rotary shaft ( 4 );
an impeller ( 5 ) including a plurality of water channels ( 50 ) formed between blades of the impellers ( 5 );
a rotor ( 6 ) including a plurality of curved grooves ( 60 ) formed on an outer surface;. and
a track assembly ( 7 ) including an annular rail ( 71 ) having ascending and descending sections formed on a bottom of the cavity ( 11 ), and a plurality of sliders ( 72 ) formed on an underside of the impeller ( 5 );
wherein the impeller ( 5 ) is disposed in the cavity ( 11 ) and mounted between the rotor ( 6 ) and the separating member ( 3 ) via the rotary shaft ( 4 );
wherein the rotor ( 6 ) is disposed in the outlet ( 10 ) below the impeller ( 5 );
wherein water flowing through the water ejection port ( 30 ) rotates the impeller ( 5 ) and further rotates the rotor ( 6 ), thereby spraying the water out of the curved grooves ( 60 ) in water particles of annular pattern;
wherein the sliders ( 72 ) are configured to move along the annular rail ( 71 ); and
wherein rotation of the impeller ( 5 ) and the ascending and descending of the sliders ( 72 ) along the annular rail ( 71 ) fluctuate the water flowing through the impeller ( 5 ), and the water flows through the rotor ( 6 ), thereby forming intermittent annular water sprays.

2. The water jet device for rotary massage of claim 1 , wherein the impeller ( 5 ) and the rotor ( 6 ) are either secured together or formed integrally; and the rotation and the fluctuation of the impeller ( 5 ) drive the rotor ( 6 ) to ascend and descend, thereby changing a distance between the curved grooves ( 60 ) and a mouth of the outlet ( 10 ) and enlarging or reducing an annular area of the water sprays.

3. The water jet device for rotary massage of claim 2 , wherein the outlet ( 10 ) has an inner diameter of 2−12mm, and the distance between the curved grooves ( 60 ) and the mouth of the outlet ( 10 ) is 2.5−8mm.
