Abstract

A multi-nozzle showerhead has a showerhead housing, a rectangular tube, multiple nozzles and a connector. The showerhead housing has a nozzle recess for each nozzle. Each of the nozzles has a diffuser, a radial impeller, a circular impeller, a diffuser housing, a selection valve, seals and a fastener. The fastener has a threaded bolt and a nut. The seals are securely mounted in each of the nozzles to prevent water leakage. Each of the nozzles is held together by the fastener with the threaded bolt and nut. The radial impeller has multiple fins, and one of the fins is an interrupt fin that momentarily interrupts the flow of water to the diffuser.

Claims

1. A multi-nozzle showerhead comprising;

a showerhead housing comprising a front housing, a rear housing and a tube;

the rear housing having an inner surface;

the tube comprising at least two tube recesses and a connector adapted to be connected to an exterior tube through which water can pass through the tube and the tub recesses;

the front housing comprising at least two nozzle recesses each with a recessed surface;

each recessed surface comprising

a nozzle inlet hole formed in the recessed surface and communicating with one of the at least two tube recesses in the tube so that the water passes through the nozzle inlet hole;

the front housing securely connected to the inner surface of the rear housing with the tube clamped between the front housing and the rear housing;

wherein nozzle is rotatably mounted in each respective at least two nozzle recesses in the front housing, and each nozzle comprises a diffuser, a radial impeller, a circular impeller, a diffuser housing, a selection valve and seals;

wherein

the selection valve is securely mounted in the corresponding one of the at least two nozzle recesses in the front housing and has first water holes communicating with the corresponding one of the at least two tube recesses in the tube;

the diffuser housing is rotatably connected to the selection valve and has second water holes selectively communicating with the first water holes in the selection valve when the diffuser housing rotates relative to the selection valve;

the circular and radial impellers are securely mounted in the diffuser housing between the diffuser housing and the diffuser;

the circular impeller has slanted through holes, and the radial impeller has a radial interrupt fin which momentarily interrupts water passing through the radial impeller during rotation of the radial impeller;

the circular impeller is adapted to direct the direction of water flow, so the radial impeller keeps rotating; and

the diffuser is securely connected to the diffuser housing, and the diffuser rotates with the diffuser housing and has third water holes communicating with the second water holes in the diffuser housing to select a particular water patterns.

2. The multi-nozzle showerhead as claimed in claim 1, wherein the first water holes in the selection valve comprise at least one inner through hole through which the water coming out of corresponding nozzle inlet hole passes.

3. The multi-nozzle showerhead as claimed in claim 2, wherein the first water holes in selection valve has at least one outer through hole through which water coming out of corresponding nozzle inlet hole can pass.

4. The multi-nozzle showerhead as claimed in claim 3, wherein the second water holes in the diffuser housing has at least one inner through hole selectively communicating with the at least one inner through hole in the selection valve and through which water coming out of the at least one inner through hole in the selection valve passes.

5. The multi-nozzle showerhead as claimed in claim 4, wherein the second water holes in the diffuser housing has at least one outer through hole selectively communicating with the at least one outer through hole in the selection valve and through which water coming out of the at least one outer through hole in the selection valve passes.

6. The multi-nozzle showerhead as claimed in claim 5, wherein the third water holes in the diffuser has at least one inner through hole communicating with the at least one inner through hole in the diffuser housing and through which water coming out of the at least one inner through hole in the diffuser housing can passes.

7. The multi-nozzle showerhead as claimed in claim 6, wherein the third water holes in the diffuser has at least one outer through hole communicating with the at least one outer through hole in the diffuser housing and through which water coming out of the at least one outer through hole in the diffuser housing can passes;

and

the diffuser has a circular groove securely connected to an inner lip formed on the diffuser housing, and the circular groove directs water either to pass through the at least one inner through hole in the diffuser or to pass through the at least one outer through hole.

8. The multi-nozzle showerhead as claimed in claim 7, wherein the inner surface of the rear housing has inner stubs, and each stub has a threaded hole;

the recessed surface of the front housing has stub holes; and

multiple screws respectively extend through the stub holes and is screwed into the threaded holes in the inner stubs to connect the front housing to the rear housing.

9. The multi-nozzle showerhead as claimed in claim 1, wherein the selection valve has a front outer groove, a rear outer groove and a inner circular groove;

seals are respectively mounted in the front outer groove, the rear outer groove and the inner circular groove to prevent water leakage.

10. The multi-nozzle showerhead as claimed in claim 1, wherein the diffuser housing has a circular inner flange, a circular outer flange and outer grooves;

seals are respectively mounted in the outer grooves and abutting the inner flange to prevent water leakage.
