Abstract

A water nozzle which includes a rotary cover, a water distribution disk, a water discharging disk, and a water admission head. The rotary cover is provided with a plurality of water emission holes of varying shapes. The water emission holes are provided with a hollow water discharging pillar, a notch located at the front end of the discharging pillars, a rib wall located between two separated water discharging pillars. The water distribution disk is provided with a large water distribution hole, a small water distribution hole, and a plurality of intermediate water distribution holes corresponding to the water emission holes, and a water slot concentric with the large water distribution hole. The water discharging disk is provided with a large water discharging hole, an intermediate water discharging hole, and a small water discharging hole, which are concentric with the large water distribution hole, the intermediate water distribution holes, and the small water distribution hole and are provided with a hollow protrusion. The cooperation between the concentric holes of the water distribution disk and the water discharging disk allows water to be emitted in varying patterns.

Claims

1. A water nozzle comprising:

a protective cover;

a multi-stepped rotary cover joined with said protective cover and actuated to turn by said protective cover, said rotary cover provided with an axial hole, and a plurality of water emission holes and meshes;

a water distribution disk provided with a center hole, and a plurality of locating slots which are equidistantly arranged along the peripheral edge thereof;

a water discharging disk provided with a center hole; and

a water admission head fastened with the barrel of a pistol nozzle and provided with a shaft rod having a water distribution duct;

wherein said rotary cover is provided in said water emission holes with a hollow water emission pillar, a notch disposed at the front end of three water emission pillars adjacent to one another, and a rib wall disposed between two water emission pillars such that said rib wall and said water emission pillars form together a closed space;

wherein said water distribution disk is provided with a large water distribution hole, a small water distribution hole, and a plurality of intermediate water distribution holes corresponding in location to said water emission holes of said rotary cover, said water distribution disk further provided with a water slot concentric with said large water distribution hole;

wherein said water discharging disk is provided with a large water discharging hole, an intermediate water discharging hole, and a small water discharging hole, which are respectively concentric with said large water distribution hole, said intermediate water distribution hole, said small water distribution hole whereby said center hole, said large water discharging hole, said intermediate water discharging hole, and said small water discharging hole of said water discharging disk is provided with a hollow protrusion circumventing the respective hole.

2. The water nozzle as defined in claim 1, wherein said water slot of said water distribution disk is of an arcuate construction whereby said water slot has a mouth with a length greater than the diameter of said protrusion circumventing said large water discharging hole of said water discharging disk.

3. The water nozzle as defined in claim 1, wherein said hollow protrusions of said large water discharging hole, said intermediate water discharging hole, and said small water discharging hole of said water discharging disk are provided with a leakproof O-ring.
