Abstract

A shower head generally comprising a face plate, an outer housing, a water chamber, a ball holder, a button, a seal, a nozzle, a screen filter, a pivot ball, and a label logo. The ball holder covers the pivot ball, wherein the pivot ball is flush with the seal which is disposed in the water chamber. In a preferred embodiment, the water chamber comprises two portions having two different diameters, wherein the ball holder is connected over the portion having the smaller diameter. The ball holder is simultaneously disposed on top of the portion having the larger diameter.

Claims

1. A shower head comprising,

an outer housing having a top and bottom opening;

a face plate enclosing said bottom opening;

a nozzle having a top and bottom face, wherein said bottom face is connected to said face plate thereof;

a water chamber having an upper portion and a lower portion connected to said top face, wherein the diameter of said upper portion is equal to or smaller than said lower portion;

a ball holder fitted in said outer housing and encased by said top opening, wherein said ball holder is secured over said water chamber;

a pivot ball connectable to a water supply, wherein said pivot ball includes a tubular portion which contains a screen filter and a spherical ball portion which is substantially surrounded by said ball holder; and

a seal disposed in an annular groove of said upper portion, said seal having a relatively rectangular or square cross-section which abuts said pivot ball, and wherein said seal is flush with the bottom of said pivot ball and annular groove along a plane.

2. The shower head of claim 1, wherein said water chamber further comprises at least one channel, centrally disposed, axially throughgoing for flow-through of water, and a plurality of concentric circles defining a plurality of bores, wherein said at least one channel communicates with said bores.

3. The shower head of claim 1, wherein a corner of said seal abutting an outer surface of the pivot ball is cut at an angle which substantially corresponds to an angle of said pivot ball at a location where the pivot ball abuts the seal, such that said seal is substantially flush against said pivot ball.

4. The shower head of claim 3, wherein the angle is from 45°

to 90°

from the vertical.

5. The shower head of claim 1, wherein said seal is flush with said upper portion when said seal is disposed in said annular groove.

6. The shower head of claim 1, wherein said water chamber comprises a threaded collar for connecting said ball holder over said water chamber.

7. The shower head of claim 1, wherein said ball holder is connected over said upper portion and disposed on top of said lower portion.

8. The shower head of claim 1, wherein said nozzle comprises a plurality of nipples on said bottom face extending outward therefrom.

9. The shower head of claim 1, wherein said face plate comprises a medial face, a lateral face, a recess disposed in the center of said lateral face for insertion of a button, a collar disposed in said medial face, and a plurality of apertures for receiving said plurality of nipples.

10. The shower head of claim 9, wherein said recess has a shape and a size that corresponds to said button.

11. The shower head of claim 1, wherein said annular groove is disposed on a recessed edge of said upper portion adjacent said channel.

12. The shower head of claim 1, wherein said outer housing further comprises a threaded portion proximate to said upper opening.

13. The shower head of claim 1, wherein said seal is made of EPDM.
