ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a water sprinkling device, and more particularly to a pistol nozzle.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a prior art pistol nozzle
01
is provided at the front end with a water inlet
02
, which is joined by a nozzle cover
03
. Located between the water inlet
02
and the nozzle cover
03
is a water emission piece
05
which is provided with a plurality of water emission holes
06
. The nozzle cover
03
is provided with a water outlet
06
from which the water is emitted.
Such a prior art pistol nozzle as described above is defective in design in that the water can not be emitted in various fashions, and that the flow of water is not stable, and further that it is not provided with a leakproof means to prevent the water leak.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide pistol nozzle which is free from the drawbacks of the prior art pistol nozzle described above.
The features and the advantages of the present invention will be readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
