ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an improved sprinkler and particularly to a sprinkler that is allowed to adjust and control spraying water according to various gardening plants.
2. Description of the Prior Art
Referring to
FIG. 1
, a conventional sprinkler
1
mainly includes a spray nozzle
11
, a barrel
12
and a hose connector
13
. The spray nozzle
11
is a hollow tube with an inner threaded section
114
for fastening the barrel
12
and a water outlet
111
on the front end. The barrel
12
has a body
120
which has a fender head
123
located on the front end thereof. Behind the fender head
123
, there are a conical section
122
and an aperture
121
. The body
120
further has a threaded section
124
in the middle section and a turning head
125
of a larger diameter on the rear end thereof for turning and adjusting water discharge amount and controlling shut off of water discharge. The turning head
125
has an inner screw hole
126
to couple with a hose connector
13
. The hose connector
13
is a hollow tube which has a front section forming a tubular head of a larger diameter with an inner opening
132
and an outer threaded section
131
, and a rear end coupling with a water outlet
134
through a nut
133
. As the water outlet
111
of the sprinkler
1
has only one water discharge opening, water is ejected out directly. While the water may be ejected to a greater distance, it also is ejected with a stronger force. It could damage flowers or newly planted young tresses. Thus such a sprinkler is not well received by gardening lovers and horticulturists.
SUMMARY OF THE INVENTION
In view of the aforesaid disadvantages, the primary object of the invention is to provide an improved sprinkler that mainly includes a spray nozzle, an adjusting sleeve, a barrel set and a hose connector. The barrel set has a turning head for controlling water discharge of a first water outlet. The adjusting sleeve can control water discharge of a second water outlet. Thus users can adjust and control the force and amount of water discharge according the plant conditions to overcome the drawbacks of the conventional sprinklers and prevent plant damages that might otherwise occur due to improper watering.
