Abstract

A shower head assembly includes a housing including a first end portion engaged with a water outlet cap and a second end portion connected to a water source. The water outlet cap defines a plurality of outer nozzles arranged in a circular manner and a plurality of inner nozzles arranged in a circular manner. An adjusting device is mounted on a periphery of the housing for alternatively introducing water in the housing into the outer nozzles or the inner nozzles such that water can be sprayed outwardly via the outer nozzles or via the inner nozzles alternatively.

Claims

1. A shower head assembly comprising:

a housing (10) including a first end portion (100) and a second end portion (102);

an abutting base (18) fitted in said housing (10) and including a first side wall abutting on an inner wall of said second end portion (102) of said housing (10) and defining a recess (180), and a second side wall defining a hole (182) communicating with said recess (180);

a circular base (30) fitted in an inner wall of said first end portion (100) of said housing (10) and including a first side and a second side, and a plurality of bores (38) defined in said circular base (30) and arranged in an annular manner;

an outer tube (31) including a first end portion extending from said second side of said circular base (30) and a second end portion abutting on said second side wall of said abutting base (18);

an inner tube (32) including a first end portion extending from said second side of said circular base (30) and a second end portion abutting on said second side wall of said abutting base (18) and defining a plurality of openings (321) along a periphery thereof, an annular duct (34) defined between said outer tube (32) and said inner tube (31) and having a first portion communicating with said bores (38) and a second portion communicating with said openings (321);

a tapered collar (33) formed on said circular base (30) and disposed in said inner tube (32), and a tapered bore (330) defined in said tapered collar (33);

a sliding barrel (20) slidably mounted in said inner tube (32) and including a closed end portion defining a plurality of cavities (24) along a periphery thereof, and an open end portion, a channel (200) defined in said sliding barrel (20) and having a first portion communicating with said cavities (24) and a second portion communicating with said hole (182) of said abutting base (18);

an urging seat (21) extending from said closed end portion of said sliding barrel (20) to slide therewith and being movable between a first position where said urging seat (21) is detached from an inner wall of said tapered collar (33) such that said cavities (24) communicate with said tapered bore (330) while said open end portion of said sliding barrel (20) is urged on said second side wall of said abutting base (18), thereby closing said openings (321) of said inner tube (32), and a second position where said urging seat (21) is urged on said inner wall of said tapered collar (33), thereby closing said tapered bore (330) while said open end portion of said sliding barrel (20) is spaced from said second side wall of said abutting base (18) such that said channel (200) communicates with said openings (321) of said inner tube (32); and

adjusting means (50) for moving said sliding barrel (20) together with said abutting seat (21) between said first position and said second position.

2. The shower head assembly according to claim 1, wherein said housing (10) defines a first socket (12) in a periphery thereof, a reinforcing wall (36) is formed between said outer tube (31) and said inner tube (32) and defines a second socket (360) aligning with said first socket (12), said sliding barrel (20) defines an oblong slot (25) in a periphery thereof and aligning with said second socket (360), and said adjusting means (50) comprises a pivot base (51) in turn rotatably extending through said first socket (12) and said second socket (360), an eccentric stub (52) eccentrically extending from a first end portion of said pivot base (51) to rotate therewith and slidably received in said oblong slot (25), and a knob (56) fixedly mounted on a second end portion of said pivot base (51) and extending outwardly from said housing (10) for rotating said pivot base (51).

3. The shower head assembly according to claim 1, wherein said urging seat (21) defines an annular groove (22) in a periphery thereof, and a sealing ring (23) is mounted in said annular groove (22) and can be tightly urged on said inner wall of said tapered collar (33) when said urging seat (21) is at its first position, and can be detached from said inner wall of said tapered collar (33) when said urging seat (21) is at its second position.

4. The shower head assembly according to claim 1, further comprising a cap (40) including a disk (43) abutting on said first end portion (100) of said housing (10), an outer ring (41) including a first end portion extending from said disk (43) and a second end portion abutting on said first side of said circular base (30), an inner ring (42) including a first end portion extending from said disk (43) and a second end portion abutting on said first side of said circular base (30), a plurality of outer nozzles (410) defined in said disk (43), disposed between said outer and inner rings, and communicating with said bores (38), and a plurality of inner nozzles (420) defined in said disk (43), disposed in said inner ring (42), and communicating with said tapered bore (330).

5. The shower head assembly according to claim 4, further comprising a rotary disk (46) rotatably abutting on said first side of said circular base (30) and defining a plurality of chutes (460) communicating with said tapered bore (330), a pivot axle (44) disposed in said inner ring (42) and including a first end portion extending from said disk (43) and a second end portion abutting on said rotary disk (46), a rotary base (45) rotatably mounted on said pivot axle (44) and including a plurality of blades (452) arranged in a circular manner.

6. The shower head assembly according to claim 4, further comprising a positioning member (47) fixedly mounted on said first end portion (100) of said housing (10) and urged on said disk (43) of said cap (40) for positioning said cap (40) in said housing (10).
