ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a shower head assembly, and more particularly to a shower head assembly, wherein the water outlet seat and the water outlet disk form a smaller water chamber, thereby reducing the bearing weight of the water outlet disk, the locking disk and the water outlet panel.
2. Description of the Related Art
A conventional shower head assembly in accordance with the prior art shown in
FIGS. 1-3
comprises a shade
11
, a water outlet panel
12
, a mounting tube
13
, a connecting head
14
, and a locking nut
15
. The shade
11
has a top formed with a mounting hole
111
and a bottom formed with a locking portion
112
. The water outlet panel
12
is formed with a plurality of water outlet holes
121
and a plurality of spraying heads
16
. A seal ring
122
is mounted on the periphery of the water outlet panel
12
. The mounting tube
13
is formed with a protruding ring
131
and an outer thread
132
. A seal washer
133
is mounted in the mounting tube
13
. The mounting tube
13
has a bottom formed with a closed face
134
and a plurality of water inlet holes
135
. The connecting head
14
has a first end pivotally mounted on the mounting tube
13
and a second end formed with an inner thread
141
. The a locking nut
15
is formed with an inner thread
151
screwed on the outer thread
132
of the mounting tube
13
and has a top formed with an urging flange
152
urged on the connecting head
14
.
However, the conventional shower head assembly has the following disadvantages.
1. The shade
11
and the water outlet panel
12
form a larger water chamber, so that the water outlet panel
12
bears a larger water pressure and load, and is easily detached from the shade
11
.
2. The shade
11
and the water outlet panel
12
form a larger water chamber, so that the conventional shower head assembly will drop water when the water supply is stopped.
3. The shade
11
and the water outlet panel
12
are combined in a rolling press manner, so that the water outlet panel
12
cannot be detached for washing the inside of the water outlet panel
12
.
4. The parts of the conventional shower head assembly are assembled by the soldering and rolling procedures, thereby increasing costs of fabrication.
5. The parts of the conventional shower head assembly are assembled by the soldering and rolling procedures, so that the shade
11
and the water outlet panel
12
are easily scratched due to hit, thereby decreasing the aesthetic quality thereof.
6. The water outlet panel
12
and the spraying heads
16
need to be processed by a screwing process, thereby increasing costs of fabrication.
SUMMARY OF THE INVENTION
The present invention is to mitigate and/or obviate the disadvantage of the conventional shower head assembly.
The primary objective of the present invention is to provide a shower head assembly, wherein the water outlet seat and the water outlet disk form a smaller water chamber, thereby reducing the bearing weight of the water outlet disk, the locking disk and the water outlet panel.
Another objective of the present invention is to provide a shower head assembly, wherein the water outlet seat, the water outlet disk, the locking disk and the water outlet panel are combined rigidly and stably without detachment.
A further objective of the present invention is to provide a shower head assembly, wherein the water stop rib of the water stop flange of the water outlet disk is rested on the inner face of the water outlet seat, and the urging section of the water stop flange of the water outlet disk is urged between the urging ring of the water outlet seat and the resting face of the protruding ring of the locking disk, thereby forming a double water stopping effect without incurring leakage.
A further objective of the present invention is to provide a shower head assembly, wherein the water outlet seat and the water outlet disk form a smaller water chamber, so that the shower head assembly will not drop water when the water supply is stopped.
A further objective of the present invention is to provide a shower head assembly, wherein the water outlet seat and the locking disk are combined by the screw members, so that the water outlet seat and the locking disk can be detached, thereby facilitating the user washing the water outlet seat.
A further objective of the present invention is to provide a shower head assembly, wherein the water outlet panel and the nozzle heads need not to be threaded, thereby decreasing costs of fabrication.
A further objective of the present invention is to provide a shower head assembly, wherein the parts of the shower head assembly can be assembled easily, rapidly and conveniently, thereby decreasing costs of fabrication.
A further objective of the present invention is to provide a shower head assembly, wherein the parts of the shower head assembly can be assembled without having to be treated by the soldering and rolling procedures, thereby enhancing the aesthetic quality thereof.
In accordance with the present invention, there is provided a shower head assembly, comprising a shade, a water outlet seat, a water outlet disk, a locking disk, a water outlet panel, a mounting tube, a connecting head, and a locking nut, wherein:
the water outlet seat is mounted in the shade and has a periphery formed with a locking flange, the water outlet seat has a center formed with a mounting body extended upward therefrom, the mounting body has an inner wall formed with a stepped hole;
the water outlet disk is mounted in the shade and rested on the water outlet seat, the water outlet disk has a periphery formed with a substantially inverted U-shaped water stop flange extended outward therefrom;
the locking disk is mounted in the shade and rested on the water outlet disk, the locking disk has a top formed with a protruding ring;
the water outlet panel is mounted in the shade and rested on the locking disk;
the mounting tube is mounted between the shade and the water outlet seat;
the connecting head is mounted on the shade; and
the locking nut is mounted on the shade and secured on a top of the mounting tube.
