1. Field of the Invention
The present invention relates to sprinkling head, and more particularly to a sprinkling head of a percussive sprinkler
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
Percussive sprinklers are extensively used for gardening and spraying, since circulating or reciprocating water sprinkling of the percussive sprinklers can be realized in an annular zone. In order to further improve its practicability, a tilting percussive sprinkler has been developed, allowing to adjust the outlet angle by tilting upwards or downwards so as to meet the user's diversified demands.
A conventional percussive sprinkler generally comprises a main body, a tubing portion located at a bottom of the main body, a percussive frame rotatably mounted on the main body and a steering structure disposed on the main body. To achieve the purpose above, the conventional percussive sprinkler needs to contain a tilting structure disposed between the tubing portion and the main body.
As a result, the cost of the percussive sprinkler must be raised. In addition, the percussive frame reciprocally impinges the main body for changing the spray direction of the percussive sprinkler when being operated to spray water. However, the reciprocally rotated percussive frame will block the water column from the main body such that the irrigating water column is choppy and the main must be rotated for several circles for providing a complete irrigating area. As a result, some water is wasted and the wet degree is not average in the irrigating area.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional percussive sprinkler
The main objective of the present invention is to provide an improved sprinkling head that includes a series of spraying holes defined therein for forming an annular irrigated area.
To achieve the objective, the sprinkling head of a percussive sprinkler in accordance with the present invention comprises a connecting portion and a protrusion vertically extending from one end of the connecting portion to form an L-shaped structure, wherein the connecting portion is adapted to be mounted onto the percussive sprinkler The connecting portion includes a recess defined in a bottom thereof and communicating with a passage in the percussive sprinkler, and an outlet defined in a top thereof and communicating with the recess such that the outlet communicates with the passage via the recess. A tunnel is defined in the protrusion and communicates with the recess and a series of spraying holes are defined in a bottom of the tunnel for forming an annular irrigating area.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The connecting portion 20 includes a recess 21 defined in a bottom thereof and communicating with the passage 41 in the percussive sprinkler 40, and an outlet 22 defined in a top thereof and communicating with the recess 21 such that the outlet communicates with the passage 41 via the recess 21. A tunnel 31 is defined in the protrusion 30 and communicates with the recess 21. A series of spraying holes 32 is radially defined in a bottom of the tunnel 31 such that each spraying hole 32 has an elevation different from one another for forming multiple slim water columns with different spray distances.
