Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of agricultural irrigation facility accessories, and in particular to a water-saving sprinkler head for agricultural irrigation. Background Technology
[0002] Agricultural irrigation involves using irrigation facilities to replenish water to crops. During this process, the sprinklers of the irrigation facilities spray water towards the target location. However, due to the limited water flow from the sprinklers, they typically need to spray water continuously for a certain period to meet irrigation needs. Furthermore, the water pressure in existing irrigation facilities is often unstable, meaning the water output from the sprinklers is inconsistent, which can easily cause the sprinklers to fail to maintain a continuous flow of water to a specific location.
[0003] When the water output force of the sprinkler is unstable, the water output from the sprinkler may spray too far, exceeding the area that needs irrigation, which will result in water waste.
[0004] Therefore, the existing nozzles have a technical problem: they cannot adjust the water output force according to the water flow pressure. Summary of the Invention
[0005] This utility model provides a water-saving sprinkler for agricultural irrigation, which solves the technical problem that existing sprinklers cannot adjust the water output force according to the water flow pressure.
[0006] Some implementation schemes for solving the above-mentioned technical problems include:
[0007] A water-saving sprinkler head for agricultural irrigation includes a sprinkler body, the sprinkler body being provided with a water storage cavity, and the sprinkler body also being provided with a nozzle, the nozzle communicating with the water storage cavity;

[0009] and an adjustment component, wherein the adjustment component controls the number of nozzles communicating with the water storage chamber according to the water pressure in the water storage chamber;
[0010] The adjustment component includes a slider slidably connected within the water storage cavity. An elastic element is provided between the slider and the cover. The elastic element pushes the slider so that all the nozzles are not in communication with the water storage cavity.

[0012] Preferably, the slider includes a cylinder, and a top plate is provided at one end of the cylinder near the cover. The top plate and the cylinder are integrally formed. One end of the elastic element contacts the top plate, and the other end of the elastic element contacts the cover.
[0013] Preferably, the top plate is provided with a positioning ring for positioning the elastic element, the positioning ring and the top plate are integrally formed, and one end of the elastic element is fitted onto the positioning ring.
[0014] Preferably, the cover is provided with a ring, and the elastic element is sleeved on the ring, and the ring and the cover are an integral structure.
[0015] Preferably, a sealing layer is provided between the slider and the side wall of the water storage cavity, and the sealing layer is adhered to the slider.
[0016] Preferably, the cover is fixed to the nozzle body by threads, the cover has internal threads, the nozzle body has external threads that mate with the internal threads of the cover, the cover has sealing ridges, the nozzle body has sealing grooves that mate with the sealing ridges, and a sealing gasket is provided between the sealing ridges and the sealing grooves.
[0017] Preferably, the nozzle body is provided with a convex ring, the cover is provided with a shoulder, a sealing ring is provided between the shoulder and the convex ring, the convex ring and the nozzle body are integral structures, and the shoulder and the cover are integral structures.

[0020] Compared with the prior art, the present invention has the following advantages:
[0021] By setting an adjustment component, the number of nozzles connected to the water storage chamber is controlled according to the water pressure in the storage chamber. That is, the more nozzles connected to the water storage chamber, the larger the water outlet area of the water-saving nozzle, and the smaller the corresponding water outlet force. When the water pressure in the storage chamber is too high, more nozzles participate in the water outlet, so that the water outlet force of the nozzles remains stable. This can prevent the water outlet force of the nozzles from being too strong, and the water outlet of the nozzles will not exceed the irrigation range, thus avoiding water waste and optimizing the performance of the water-saving nozzles.
[0022] By using a slider and an elastic element, the slider is used to close the nozzle. When the slider aligns with the nozzle, the nozzle is closed, and water cannot flow from it. When the slider and nozzle are misaligned, water can flow normally. The elastic element pushes the slider to move, and the water pressure in the water storage chamber overcomes the pressure of the elastic element, causing the slider to move and thus partially connecting the nozzle with the water storage chamber to achieve water spraying. When the water pressure in the water storage chamber fluctuates, the slider's position changes under the action of the elastic element, thereby achieving an automatic position adjustment function. This keeps the water flow force of the nozzle stable and simplifies the structure of the adjustment component. Attached Figure Description

[0035] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.
[0036] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.
[0037] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0038] Reference Figures 1 to 7 As shown, a water-saving sprinkler for agricultural irrigation includes a sprinkler body 1, the sprinkler body 1 being provided with a water storage chamber 11, and the sprinkler body 1 also being provided with a nozzle 12, the nozzle 12 being in communication with the water storage chamber 11.
[0039] Cover 2 is disposed on the nozzle body 1, and the cover 2 closes the water storage cavity 11;
[0040] And adjustment component 3, the adjustment component 3 controls the number of nozzles 12 communicating with the water storage chamber 11 according to the water pressure in the water storage chamber 11;
[0041] The adjustment component 3 includes a slider 31 slidably connected to the water storage cavity 11. An elastic element 32 is provided between the slider 31 and the cover 2. The elastic element 32 pushes the slider 31 so that all the nozzles 12 are not in communication with the water storage cavity 11.
[0042] Specifically, the more nozzles 12 participate in water spraying, the larger the water outlet area of the corresponding water storage chamber 11 becomes. The larger the water outlet area of the water storage chamber 11, the smaller the water outlet force. Therefore, when the water pressure in the water storage chamber 11 changes, the slider 31 automatically changes position under the action of the elastic element 32 and the water pressure, thereby changing the number of nozzles 12 participating in water spraying, so that the water outlet force of the nozzles 12 remains stable.
[0043] Water pressure refers to the pressure of the water inside the water storage chamber 11.
[0044] In some embodiments, the elastic element 32 pushes the slider 31 downward, causing the nozzles 12 to be closed by the slider 31, at which point the nozzles 12 cannot discharge water. That is, in non-irrigation conditions, the water in the water storage chamber 11 is closed by the slider 31 and not connected to the outside, which can reduce the evaporation efficiency of the water retained in the water storage chamber 11 and further reduce the waste of water resources.
[0045] During irrigation, the water supply pipe supplies water to the water storage chamber 11. At this time, the water pressure in the water storage chamber 11 changes. Under the action of water pressure, the water in the water storage chamber 11 overcomes the elastic force of the elastic element 32, causing the slider 31 to move upward. At this time, some of the nozzles 12 are opened, and the nozzles 12 can output water normally to achieve irrigation.
[0046] The position of slider 31 is determined by water pressure. Therefore, the amount of water dispensed by nozzle 12 during irrigation does not need to be manually adjusted. The adjustment can be completed automatically by water pressure, thus optimizing the performance of the water-saving nozzle.
[0047] Reference Figures 1 to 7 As shown, in practice, sprinklers typically spray water around the area to irrigate a larger area; therefore, the more sprinklers there are, the more beneficial the irrigation operation. In some embodiments, the sprinkler body 1 includes a cylindrical portion 111 forming the water storage chamber 11, the nozzles 12 being evenly distributed in the cylindrical portion 111, and the sprinkler body 1 also includes a mounting portion 13, which is integrally formed with the cylindrical portion 111, and the inner cavity of the mounting portion 13 communicates with the water storage chamber 11.
[0048] The water pressure inside the water storage chamber 11 is constant. Therefore, the force exerted by the water in the water storage chamber 11 to move the slider 31 is limited. In practice, the lighter the slider 31, the more sensitive it is to move under water pressure. In some embodiments, the slider 31 includes a cylindrical body 311. A top plate 312 is provided at one end of the cylindrical body 311 near the cover 2. The top plate 312 and the cylindrical body 311 are integrally formed. One end of the elastic member 32 contacts the top plate 312, and the other end of the elastic member 32 contacts the cover 2.
[0049] Reference Figures 1 to 7As shown, the elastic element 32 may undergo plastic deformation during long-term use. To extend the service life of the elastic element 32, a guide structure should be provided for the elastic element 32 to prevent bending deformation. In some embodiments, the top plate 312 is provided with a positioning ring 313 for positioning the elastic element 32. The positioning ring 313 and the top plate 312 are integrally formed, and one end of the elastic element 32 is fitted onto the positioning ring 313. The cover 2 is provided with a ring body 21, and the elastic element 32 is fitted onto the ring body 21. The ring body 21 and the cover 2 are integrally formed.
[0050] In some embodiments, the elastic element 32 may be a spring. The elastic element 32 may also be replaced by other structures with elastic deformation capabilities.
[0051] In some embodiments, the two ends of the spring are guided by a positioning ring 313 and a ring body 21, respectively, making the spring less prone to bending deformation during long-term use. The spring can be fixed to the top plate 312 and the cover 2 by welding. Alternatively, the spring may not be fixed to the top plate 312 and the cover 2, but only needs to contact the top plate 312 and the cover 2.
[0052] In some embodiments, a sealing layer is provided between the slider 31 and the side wall of the water storage cavity 11, and the sealing layer is adhered to the slider 31. The sealing layer has good sealing performance, preventing water in the water storage cavity 11 from leaking between the slider 31 and the side wall of the water storage cavity 11.
[0053] Reference Figures 1 to 7 As shown, the cover 2 and the nozzle body 1 should have good sealing performance to prevent water leakage from the water storage chamber 11. In some embodiments, the cover 2 is fixed to the nozzle body 1 by threads. The cover 2 is provided with internal threads, and the nozzle body 1 is provided with external threads that mate with the internal threads of the cover 2. The cover 2 is provided with a sealing ridge 22, and the nozzle body 1 is provided with a sealing groove 112 that mates with the sealing ridge 22. A sealing gasket is provided between the sealing ridge 22 and the sealing groove 112.
[0054] In some embodiments, the nozzle body 1 is provided with a convex ring 113, the cover 2 is provided with a shoulder 23, and a sealing ring 231 is provided between the shoulder 23 and the convex ring 113. The convex ring 113 and the nozzle body 1 are integral structures, and the shoulder 23 and the cover 2 are integral structures.
[0055] The shoulder 23 of the convex ring 113 increases the sealing area of the sealing ring 231, resulting in better sealing performance between the cover 2 and the nozzle body 1.
[0056] Water-saving sprinklers are typically installed on the water supply pipes of irrigation facilities. A good seal should exist between the sprinkler and the water supply pipe to prevent water leakage. In some embodiments, the mounting portion 13 is provided with a shoulder 131 that increases the contact area with the object being connected. A sealing plate is provided on the side of the shoulder 131 that contacts the object being connected, and the sealing plate is adhered to the shoulder 131.
[0057] Reference Figures 1 to 7 As shown, in some embodiments, the shoulder 131 and the mounting part 13 are an integral structure, and the mounting part 13 is also provided with threads, and the mounting part 13 is fixed to the connected object by the threads.
[0058] The object being fixed refers to the water supply pipe. The shoulder 131 and the sealing plate provide a larger contact area between the mounting part 13 and the water supply pipe, thereby providing better sealing performance between the mounting part 13 and the water supply pipe, and reducing the likelihood of leakage between the mounting part 13 and the water supply pipe.
[0059] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.
[0060] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
