ABSTRACT:
BACKGROUND OF THE INVENTION
1) Field of the Invention
The invention relates to an improved sprinkler structure to modify the defects found in traditional sprinklers. Especially, through the particular structural design for the invention, during the process of spraying water in a garden, the sprinkler sprays foggy water against a user from the side of the sprinkler facing the user. The invention is characterized as providing a cool and comforting effect for a user.
2) Description of the Prior Art
As shown in
FIG. 1
, currently there are various structural types of sprinklers
2
on the market. The structure is mainly comprised of molded handle
21
and a sprinkler
22
with internally connected waterways
23
. A valve bar
24
inside the water has an extension end
27
extruded out of the sprinkler
22
and is connected with compression board
25
by a screw. A valve opening
26
with a contracted diameter is located at the front end of waterway
23
. Thus, valve bar
24
can block valve opening
26
to prevent water spraying from water outlet
29
. If valve bar
24
is compressed by compression board
25
and moves backward, water in waterway
23
will flow through water outlet
29
and will spray from water outlet
29
.
For all the various types of sprinkler products, through the compression of compression board
25
, valve bar
24
on sprinkler
2
is forced to move backward, thus water is able to pass through waterway
23
and water outlet
29
and finally sprays from water outlet
29
. During the application process, water is directly sprayed from water outlet
29
on sprinkler head
28
of sprinkler
2
.
However, sprinkler
2
is mainly utilized in common outdoor gardening. The plant in a garden must be constantly sprayed with water, especially during sunny days. Usually, water spraying is carried on outdoors and in sunny conditions. Thus, during the water spraying process, a user must also bear sunshine, which is a tedious task for a user.
Therefore, on the basis of the above defects for traditional sprinklers to be overcome, the inventor researched product improvement according to tremendous sales, fabrication, and assembly experience in various gardening and water supply hardware together with consumer reply and personal experience. With the accumulated yearly experience and study results, the inventor developed this invention.
SUMMARY OF THE INVENTION
The primary objective of the invention is to provide an improved structure for a sprinkler having a molded handle and sprinkler with internally connected waterways. A valve bar inside the waterway has an extension end extruded out of the sprinkler and connects with a compression board through a screw. A valve opening with a contracted diameter is located at the front end of the waterway. Thus, the valve bar can block the valve opening to prevent water spraying from the water outlet. If the valve bar is moved backward by a compression board, water will flow through the water outlet. The sprinkler has, near the side held by a user, a water outlet column connected with the internal waterway inside the sprinkler. A foggy water spray base, which is able to produce foggy water and control the water flow is connected to the surrounding edge of the column. During the process of using the sprinkler to spray water against the outdoor plant in common outdoor gardens, the front end of the sprinkler can not only spray water against the various plants, as common sprinklers, but also is able to spray foggy water against a user. The invention is characterized by providing cool and comfortable effects to the user during the water spraying process.
The following are brief descriptions of the illustration for optimal explanation of the invention.
