1. Field of the Invention
The present invention relates to a sprinkler, and more particularly to a horizontal percussive sprinkler that has a shortened water path.
2. Description of Related Art Including Information Disclosed under 37 CFR 1.97 and 37 CFR 1.98.
Conventional sprinkling products in accordance with the prior art include the types of hand-held sprinkling gun, upright sprinkler, placing sprinkler and hanging sprinkler As usual, the placing sprinkler is put or selectively secured on the ground for easily changing the position thereof.
The conventional sprinkling elements of the placing sprinkler have various types, such as rotating type or reciprocally swing type. The conventional sprinkler usually uses a gear box for reciprocally swinging the spray head thereof. However, the gear box for conventional sprinkler is too expensive and complicated such that some sprinkler manufacturers provide a percussive sprinkler that uses a percussive spraying head for changing the spraying angle of the spraying hole thereof and a steering control device for limiting the angle range of the spraying hole.
However, the conventional percussive sprinkler has the disadvantages as follow. The spraying element of the conventional percussive sprinkler is elongated such that the water current firstly passes the guide frame and flow to the spraying tube. As a result, the guiding tube is elongated and complicated and the leaking probability is raised. In addition, the opposite ends of the spraying tube of the conventional sprinkler are respectively limited by the guiding element and the base thereof such that irrigating type is unchanged.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional sprinklers.
The main objective of the present invention is to provide an improved percussive sprinkler that has a watering tube disposed before a spray head thereof for promoting an irrigating effect.
To achieve the objective, the percussive sprinkler in accordance with the present invention comprises a base including a supporting portion and a mounting portion extending from the supporting portion. An inlet pipe extends from the mounting portion a pipe coupling element is mounted into the mounting portion and communicating with the inlet pipe. A guide frame is rotatably disposed onto the mounting portion and includes a tubular element rotatably received in the pipe coupling element. A spray head is formed on a free end of the tubular element. A percussive frame is pivotally mounted onto the spray head for reciprocally impacting the spray head. A resilient member is disposed in the guide frame and connected to the percussive frame for providing restitution force to the percussive frame. A steering control device is sleeved on the tubular element for controlling the steering range of the guide frame. The steering control device includes a limiting element rotatably sleeved on the tubular element and a linkage secured on the guide frame, wherein the limiting element and the linkage respectively correspond to the tubular element of the guide frame for adjusting and controlling the swing range of the guide frame. A watering tube is mounted onto the guide frame from spraying water from the inlet pipe. The water tube is divided into an insertion portion and a horizontal portion, wherein multiple spray holes are defined in the horizontal portion. The insertion portion communicates with a tube coupling that radially extends from the tubular element such that the water tube is swung with the guide frame and the water tube communicates with the tubular element. As a result, the water from the inlet pipe firstly flows into the watering tube and waters through the spray holes before flowing into the spray head.
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
By the structures described above, the water is guided into the guide frame 30 by the inlet pipe 20, along the direction of the arrow L1 in
The insertion portion 41 of the watering tube 40 can be detached from the tube coupling 36 on the tubular element 31 of the guide frame 30 such that the tube coupling 36 in accordance with the present invention is suitable to watering tubes 40 with various types. In addition, the tube coupling 36 extends from a top portion of the tubular element 31 of the guide frame 30 and there is no other structure disposed over the watering tube such that the watering tube 40 can be easily detached from the tube coupling 36 when the watering tube 40 is designed as a detachable type. Consequently, the manufacturer can provide various watering tubes 40 for different irrigating effects.
With reference to
With reference to
The supporting portion 11 of the base 10 is used as a seat that is disposed on the ground. With reference to
With reference to
As described above, the tube coupling 36 in accordance with the present invention extends from the tubular element 31 near the inlet pipe 20 for receiving the insertion portion 41 of the watering tube 40 such that the water from the inlet pipe 20 firstly flows into the watering tube 40 and waters through the spray holes 42 before flowing into the spray head 32. As a result, the total length and the probability of water-clock of the percussive sprinkler are reduced. In addition, the watering tube 40 can be replaced relative to the user's purpose and the irrigating type for promoting the using scope of the percussive sprinkler in accordance with the present invention.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
