The present invention relates to nozzle, and particular to a nozzle with adjustable spout range.
In accordance of a U.S. Pat. No. 5,769,322, a rotary sprinkler and a base are disclosed. A lateral side of a base has a water inlet, and a water outlet formed to an upper end thereof. A round disk is arranged around the water outlet. A plurality of spacing hole is formed to the round disk with predetermined gap between. A plurality of adjusting foot is formed below an elastic round track formed around the water outlet. The plurality of the adjusting foot can be inserted into the plurality of spacing hole for specific height adjustment. An automatical spinning sprinkler driven by water is connected upon the water outlet. A plurality of nozzle arranged vertically is formed to a later side of the sprinkler with a predetermined angle of elevation. A diversion plate arranged to the sprinkler has extending diversion sheet formed above the nozzle. A bent down linking rod is arranged to an opposite side of the diversion plate to the diversion sheet. A spring is arranged between the linking rod and the diversion plate so that a bottom of the linking rod is attached to the round track and being up and down on the track.
Therefore, while water coming into the sprinkler, the sprinkler is spinning with spout coming out from the nozzles. The diversion plate and the diversion sheet spinning with the sprinkler will be swung up and down by levering of the linking rod. The spout of the nozzle will not be blocked by a up-raised diversion sheet so as to reach a far range. In the contrary, the spout of the nozzle will have a short range while the spout is blocked by a lowered diversion sheet.
The above assembly can achieve a ranged control by the diversion sheet as another U.S. Pat. No. D297255 “Sprinkler head” by the same inventor which only has a different outer appearance. However, the two inventions still have disadvantages needed to be corrected as the following.
1. The water flowing through the nozzle cannot be adjusted so that the spout blocked by a lowered diversion sheet will cause strong splash of water which might damage flowers and plants.
2. While the spring linking the diversion plate and the linking rod is inactive, the diversion sheet will no longer change a position to adjust the range of spout.
Accordingly, a primary object of the present invention is to provide a sprinkler with automatic water flow control depending on a range of a spout.
Normally, protrusions of a transverse axle hole are away from water outlets of the transverse axle tube so that the water outlets are not blocked by the protrusions. A water way of a mobile tube has the largest angle of elevation. Water coming from a vertical water way of the base will flow into a transverse water way of the transverse axle tube. Through the water outlets of the transverse water way, water will flow into a transverse axle hole and the mobile tube so as to be sprinkled out of a nozzle through the water way of the mobile tube. Water will be sprinkled to the farthest range because there is no obstacle against the water flow in such circumstance.
While the mobile tube is pivoted on the transverse axle tube, the angle of elevation of the mobile tube is changed and the protrusions will be moved to cover the water outlets or entirely block the water outlets. Therefore, while the angle of elevation of the mobile tube is lowered, water flow will be decreased so that the range of the spout out of the nozzle will be shortened.
Besides, two water seals are arranged between the transverse axle tube and the transverse axle hole. The two water seals are arranged to two relative outer side of the water outlets of the transverse axle tube. In the embodiment, the water seal is located between an inner ring and an outer ring, and the assembly is arranged to the transverse axle hole of the mobile tube.
In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
Referring to
The base 10 has a vertical water way 11. A transverse through hole 12 is formed near an upper end of the vertical water way 11. A link tube 13 is arranged at a bottom of the vertical water way 11. The link tube 13 can be connected to a water outlet 102 of a sprinkler seat 100 as shown in
The transverse axle tube 20 has an axial transverse water way 21 formed inside the transverse axle tube 20. An open end 211 is formed to an end of the transverse water way 21, the open end 211 is connected to the transverse through hole 12. Another end of the transverse water way 21 has a close end 212. At least one water outlet 22 is formed to a peripheral of the transverse axle tube 20, the plurality of the water outlet 22 communicates the transverse water way 21.
The mobile tube 30 has an axial water way 31 formed inside the mobile tube 30. A water outlet 311 is formed to an end of the water way 31. An nozzle 32 capable of extending a range of the spout can be arranged to the water outlet 311. Another end of the water way 31 is connected to a transverse axle hole 33. The transverse axle hole 33 is formed to the mobile tube 30 near the water outlet 311, and the transverse axle hole 33 is perpendicular to the water way 31. The transverse axle tube 33 can receive the transverse axle tube 20. The transverse axle hole 3 has a plurality of protrusions 331 formed on an inner wall thereof. The plurality of the protrusion 331 matches to the plurality of the water outlet 22 of the transverse axle tube 20, the plurality of protrusion 331 can block the plurality of water outlet 22. Another end of the mobile tube 30 opposite to the water way 31 has an extension portion 34 bent downward so that a center of gravity of the mobile tube 30 is close to the extension portion 34 while the transverse axle hole 33 is regarded as a pivot.

Besides, two water seals 40 are arranged between the transverse axle tube 20 and the transverse axle hole 33 as shown in
Moreover, the close end 212 of the transverse axle tube 20 is inserted into a support frame 50 for better positioning as shown in

Therefore, while the link tube 13 of the vertical water way 11 is connected to the water outlet 102 of the sprinkler base 100, the nozzle will be swung and rotated by the driving of water flow. The extension portion 34 of the mobile tube 30 will touch the round track 104 and swung up and down for adjust water flow and spout range as needed.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
