BACKGROUND OF INVENTION

Field of Invention

The present invention relates to a garden sprinkler, and more particularly to an adjustable garden sprinkler.

Description of the Related Art

Sprinklers are very common devices for horticultural irrigation work. Usually, its structure includes a water inlet, a water outlet, and an angle rotation control member. The angle rotation control member swings to make all angles evenly sprinkled. However, the water flow enters the sprinkler from the water inlet, and then the water is sent out from the sprinkler outlet. There is only a single mode of sprinkling. The amount of water sprayed and its mode cannot be adjusted which can cause wasting water. In order to adjust the flow rate of the sprinkler, it needs to be replaced by another sprinkler with a different outlet.

Therefore, it is desirable to provide a garden sprinkler to mitigate and/or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

An objective of present invention is to provide an adjustable garden sprinkler.

To achieve these and other objects of the present invention, a garden sprinkler has an input base, an output member rotatably installed at the top of the input base, and a rotating member capable of driving the output member. The output Both sides of the output member are respectively equipped with a first outlet and a second outlet. The first outlet is equipped with a first sprinkler, and the second outlet is equipped with a second sprinkler and an adjusting sleeve. The second sprinkler is a side outlet and is screwed with the adjusting sleeve. The second sprinkler can be adjusted by the adjusting sleeve, which improves the convenience of sprinkling operation without multiple sprinkler heads. Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

First, please refer toFIGS.1,2and3. A garden sprinkler comprises: an input base10, an output member20and a rotating member30. The input base10comprises a base tube11, an axial tube12, and an elastic member13. The base tube11respectively has a central axial aperture111at top end and a lower end, and a threaded section112, a non-column shaped engaging section113and an inserting section114with a smaller diameter sequentially arranged from bottom to top. The axial tube12is capable of being inserted into the central axial aperture111of the base tube11from a bottom side and has a protruding lip121with a groove122at a bottom end pushing against the bottom side of the base tube11. Furthermore, the protruding lip121has a connecting portion123with an outer threaded portion protruding from the inserting section114at a top end of the axial tube12. Two sides of the output member20respectively have a first outlet21and a second outlet22, and the first and second outlet apertures21,22are connected with each other and pass through an assembling portion23with an inner threaded section disposed at a bottom of the output member20. Moreover, the first outlet21comprises a first sprinkler24, the second outlet22comprises a second sprinkler25and an adjusting sleeve26. The second sprinkler25has an attaching portion251with an outer threaded portion, and the attaching portion251is mounted at the second outlet22. The second sprinkler25further has a larger section252, a smaller section253and an adjusting end254, and a screw portion255is disposed between the attaching portion251and the larger section252. The screw portion255has a polygonal shape. The larger section252has an outer threaded portion, the smaller section253has an outlet aperture256on a side, and the adjusting end254has a T-shaped cross-section and protruding from a front end of the smaller section253. The adjusting sleeve26has an assembling portion261with an inner threaded section engaging with the larger section252, and an inner diameter of the adjusting sleeve26is larger than the smaller section253to define a collecting space262. A diverging spout263is disposed at a front end of the adjusting sleeve26, and the diverging spout263and the collecting space262are connected by an exporting opening264. The exporting opening264has having an inner diameter larger than an outer diameter of the adjusting end254. A ring groove265is disposed between the assembling portion261and the collecting space262, and the ring groove265is provided with an O ring266pushing against the smaller section253of the second sprinkler25. The output member20and the rotating member30are respectively connected to a scroll spring27, the rotating member30is positioned by a shaft bolt28, the rotating member30has a first swinging arm31and a second swinging arm32, and the scroll spring27aligns the first and second swinging arm31,32with the first and second outlets21,22. Furthermore, the first swinging arm has a pushing portion311facing the first sprinkler24.

For the assembly, please refer toFIGS.1-4again. The assembling portion23of the output member20is screwed onto the connecting portion123of the axial tube12, and the assembling portion23abuts the elastic member13to maintain a gap from the base tube11. With rotation of the axial tube12and the base tube11, the output member20can rotate with the axial tube12, and the output member20is rotatably assembled on the top of the input base10. The first and second outlets21,22of the output member20are respectively installed on the first and second sprinklers24,25. Furthermore, the second sprinkler25is employed with the adjusting sleeve26, through the rotation of the adjusting sleeve26to adjust the relative positions among the diverging spout263, the exporting opening264and the adjusting end254and to control the water output mode of the second sprinkler25. The output member20is equipped with a scroll spring27to be installed on the rotating member30, and the shaft bolt28is configured to secure the combination such that the rotating member30is capable of rotating around the shaft bolt28to push the output member20for rotation.

For actual use, please refer toFIGS.1and4. The sprinkler is installed on a bracket40with the input base10, and is connected to a water source to divert water to the first and second outlets21,22of the output member20through the axial tube12, and then sprays water from the first and second sprinkler heads24,25. As shown inFIGS.5and6, the adjusting end254of the second sprinkler25passes through the exporting opening264and is disposed in the diverging spout263. Meanwhile, when the water flows from the outlet aperture265into the collecting space262and injects from the front of the adjusting sleeve26, due to the end of the adjusting end254is larger than the exporting opening264, which allows a larger amount of water flow to pass through and spray out from the diverging spout263to form a large range but relatively close spray performance. The range and density of the spray performance can be changed by the fine adjustment of the adjusting sleeve26.

Secondly, when the adjusting sleeve26is rotated toward outside, as shown inFIGS.7and8, the exporting opening264is blocked by the adjusting end254, the space allowing the water flow to pass is reduced, so that the water flow can only be squeezed out from the gap between the exporting opening264and the adjusting end254. Therefore, the enhanced spraying intensity of the water stream forms a water column with a smaller spraying range but a longer distance by adjusting the adjusting sleeve26.

Furthermore, as shown inFIGS.9,10, and11, the first swing arm31of the rotating member30has a pushing portion311facing the first sprinkler24. When the water flows is ejected from the first sprinkler24of the first outlet21, it pushes the pushing part311to swing and move away from the first sprinkler24, and then the scroll spring27pulls the first swing arm31to swing back and drive the output member20to swing and rotate around with the axial tube12on the top end of the base tube11.

With the structure of the above specific embodiment, the following benefits can be obtained: the second sprinkler25of the output member20is a side water outlet and is used with an adjusting sleeve26in a screw combination, so that the second sprinkler25can be adjusted by rotating the adjusting sleeve26, which improves the convenience of sprinkling operation without multiple sprinkler heads. Moreover, the output member20and the input base10are combined together to facilitate the replacement and maintenance of the output member20according to the different needs of sprinkling operations, so as to achieve a variety of sprinkling modes.
