ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a water sprinkling device, and more particularly to a base of the water sprinkling device.
BACKGROUND OF THE INVENTION
As shown in
FIGS. 1-3
, a water sprinkling device of the prior art is composed of a base
11
, a rotary member
17
, and an urging member
22
.
The base
11
comprises a handle
12
, a connector
13
, an water outlet
14
having a washer
15
, and a slot
16
.
The rotary member
17
is rotatably mounted on the base
11
by a spindle
18
and is provided with a plurality of nozzles
20
in communication with the water outlet
14
via the connection tubes
19
. The rotary member
17
is further provided with a locating slot
21
.
The urging member
22
of an L-shaped construction is Located in the slot
16
of the base
11
and is composed of an arcuate rod
23
and an urging rod
24
corresponding in location to the locating slot
21
of the rotary member
17
.
Such a prior art water sprinkler as described above is defective in design in that the water outlet
14
is vulnerable to leakage, and that the motion of the rotary member
17
is hindered at such time when the rotary member
17
is tightened to prevent the leakage of the water outlet
14
.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a leakproof water sprinkler.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a water sprinkling device having a base, a rotary member, and an urging member. The base is provided with a water outlet and two retainers contiguous to the water outlet. The rotary member is provided around the bottom edge thereof with a circular rib, which is retained securely by the retainers so as to prevent the water leakage of the water outlet of the base.
The foregoing objective, features and functions of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of an embodiment of the present invention with reference to the accompanying drawings.
