[0001] The utility model relates to a kind of sprinkling equipment for irrigating garden or farm, more particularly to a kind of elevating type sprinkler head assembly, which can be raised by water pressure to open the circumferential water outlet. BACKGROUND

[0002] Sprinkler head assembly for garden or farm is a key component in irrigation system, mainly used for evenly spraying water on plants or crops, its components include:

[0003] Sprinkler head body has one or more water outlets, water is sprayed through these outlets to form sprinkling effect.

[0004] Filter screen: generally located at the water inlet of sprinkler head body, used for filtering impurities in water.

[0005] Rotary mechanism: some sprinkler head assemblies are equipped with rotary mechanism, which can make sprinkler rotate around certain axis, so as to expand water spraying range and realize more uniform irrigation. Rotary mechanism is usually composed of motor, gear or worm gear, etc., which drives sprinkler to rotate by power.

[0021] The utility model further preferably provides: a housing is arranged outside the pedestal, and the lower end of the housing is provided with internal threads for connecting an external water pipe or a matching device.

[0022] Another preferred subject: a lifting sprinkler head assembly for irrigating gardens or farms, comprising a head, a base, a water distributor, a shaft and a protective sleeve;

[0026] The shaft, the plug and the head can be lifted together by water pressure, the return spring is compressed, the annular water outlet is opened, and a plurality of grooves for guiding water flow are distributed on the conical outer wall of the head to rotate the head.

[0027] A further preferred technical solution of the utility model is that: in the plurality of grooves, the inner section of at least one groove is a straight guide groove, and the outer section is an inclined force receiving groove, and the straight guide groove and the inclined force receiving groove are communicated.

[0032] Compared with the prior art, the lifting type spray head assembly for irrigating gardens or farms has the advantages that: through the unique structure, the problem that the traditional spray head is easily blocked when not in use is effectively solved. Specifically, the spray head is tightly seated in the concave cavity of the base under the thrust of the reset spring in the initial state, and the annular water outlet between the spray head and the base is in a closed state. This technical means enables the spray head to be completely closed in the non-working state, effectively prevents sundries and dust from entering the spray head, and avoids the blockage of the water outlet and the water flow channel. When the irrigation system starts, the water pressure acts on the plug, pushes the shaft, the plug and the spray head to lift together, the annular water outlet is opened, and the water flow starts to spray.

This automatic reset mechanism not only simplifies the operation process, but also further enhances the reliability and stability of the equipment, reduces the maintenance cost and time.

[0033] In addition, when the spray head assembly is working, the water pressure pushes the spray head to lift and open the annular water outlet, and the water flow is sprayed outward along the grooves on the conical outer wall of the spray head. These grooves not only guide the direction of the water flow, but also cooperate with the water pressure to make the spray head rotate under the reaction force of the water flow. And when the spray head rotates to spray, the water lines sprayed by adjacent grooves do not interfere with each other, and the spraying path of each water line is clear and uniformly distributed. Through the uniform distribution of the water flow and the stable rotation of the spray head, the spray head assembly can realize more efficient and more uniform irrigation coverage, significantly expand the spraying range, and improve the irrigation efficiency.

[0034] In summary, in the technical scheme, the lifting type spray head assembly for irrigating gardens or farms has a compact structure. By skillfully integrating the spray head, the base, the water distributor, the shaft and the protective sleeve and other key components together, the entire assembly not only has a small size, but also has a stable structure and stronger wind resistance. This compact structure layout not only saves installation space, but also reduces manufacturing cost, so that the spray head assembly has stronger competitiveness in the market. In addition, by optimizing the functions and synergistic effect of each component, the assembly not only realizes efficient irrigation, but also reduces the dependence on complex mechanical structures and external power devices, further reducing maintenance costs and use difficulty. The lifting type spray head assembly of the technical scheme is not only suitable for small-area garden irrigation, but also can meet the needs of large-area farm irrigation, and has wide applicability and popularization value.

[0047] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive, exemplary and should not be interpreted as limiting the scope of the present application.

[0048] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0049] In the description of this utility model, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Similarly, "first" and "second" are only for ease of understanding and have no other directional meaning, and cannot be considered as limitations on this utility model.

[0050] like Figures 1 to 4 As shown, the liftable sprinkler head assembly 100 for irrigating gardens or farms is a high-efficiency, clog-resistant irrigation device. Its ingenious structure effectively solves the problem of traditional sprinkler heads clogging easily when not in use, while simultaneously achieving uniform irrigation and automatic lifting functions. The assembly includes a sprinkler head 10, a base 20, a water distributor 30, a shaft 40, and a protective sleeve 50. All components work together to ensure the sprinkler head maintains good performance in both active and inactive states.

[0051] The upper end of the protective sleeve 50 is tightly connected to the lower end of the base 20, forming a stable support structure. The water distributor 30 is installed in the inner cavity h formed between the protective sleeve 50 and the base 20, serving to distribute the water flow. The nozzle 10 is located above the water distributor 30 and embedded in the recess f formed by the base 20. The water distributor 30 has a central shaft hole 31 through which a shaft 40 passes and connects to the nozzle 10. This structure allows the nozzle 10 to initially sit tightly within the recess f of the base 20, with the annular spray nozzle g in a closed state, effectively preventing debris from entering the nozzle, avoiding blockages, and thus extending the equipment's service life.

[0052] like Figure 6 As shown, when the irrigation system is started and water flows into the sprinkler head assembly, the water pressure pushes the shaft 40 and the sprinkler head 10 upwards together. This process not only forms an annular spray nozzle g between the sprinkler head 10 and the base 20, but also causes the sprinkler head 10 to rotate under the action of the water flow through the numerous water-guiding grooves 11 distributed on the conical outer wall of the sprinkler head 10. This technique enables the water to be sprayed more evenly, expanding the irrigation area and improving irrigation efficiency.

[0053] Furthermore, a plug 60 is provided at the bottom of the shaft 40, and a retaining ring 70 is provided inside the protective sleeve 50, such as...Figures 5 to 7 , Figure 10 As shown, a return spring 80 is installed between the plug 60 and the retaining ring 70. The return spring 80 provides elastic force when there is no water pressure, ensuring that the nozzle 10 can automatically return to its original position and sit in the recess of the base 20, closing the annular spray nozzle g, as shown. Figure 5 As shown, this automatic reset mechanism not only simplifies the operation process but also further enhances the reliability and stability of the equipment. Through the action of the reset spring 80, the sprinkler head 10 remains closed when not in use, effectively preventing debris from entering. Simultaneously, it can respond quickly when needed, achieving automatic opening and closing, greatly improving the automation level and maintenance convenience of the irrigation system.

[0054] Preferably, a filter screen 90 is provided on the outside of the protective sleeve 50, further improving the anti-clogging performance of the sprinkler head assembly. The filter screen 90 can effectively filter the water flowing into the sprinkler head assembly, intercepting impurities, silt, and particles in the water, preventing these impurities from entering the sprinkler head or clogging the spray nozzles and water flow channels. By setting the filter screen 90 on the outside of the protective sleeve 50, the possibility of clogging is reduced from the source, and the service life of the sprinkler head assembly is extended, ensuring that the sprinkler head maintains good water spraying effect and irrigation performance during long-term use.

[0055] More specifically, such as Figure 8 As shown, the water distributor 30 in this embodiment includes a connecting part 33 and a head 32. The connecting part 33 is connected to the protective sleeve 50. The design of the head 32 enables more efficient water distribution, ensuring that the water flows evenly into the spray head 10, thereby achieving a more uniform spraying effect. The tight connection between the connecting part 33 and the protective sleeve 50 provides a more stable support for the entire spray head assembly. This structure can effectively prevent the water distributor 30 from shifting or loosening during water flow impact or long-term use.

[0056] In addition, such as Figure 9 As shown, the head 32 of the water distributor 30 has a first conical surface s1, and the outer wall of the base 20 has a second conical surface s2. The first conical surface s1 and the second conical surface s2 form an annular diffuser s3.

[0057] First, it should be noted that, as Figure 6 As shown, the combination of the first conical surface s1 and the second conical surface s2 forms an annular diffuser s3, which ultimately serves to further diffuse the water flow distribution as it is guided from the distributor 30 to the nozzle 10. This diffusion effect ensures that the water flow forms a relatively uniform distribution before entering the nozzle 10, thus providing a basis for uniform spraying from the nozzle.

[0058] When the water flow passes through the annular diffusion port s3, the kinetic energy of the water flow is reasonably distributed, reducing the impact force of the water flow when entering the nozzle, so that the water flow can enter the groove 11 of the nozzle more smoothly, thereby realizing more uniform and stable spraying effect.

[0059] In addition, the annular diffusion port s3 is uniformly arranged with each interval or cooperates with the groove 11 under other regular arrangement, which can further optimize the direction and pressure distribution of the water flow, thereby enhancing the rotation effect of the nozzle and the spraying effect of the water flow ray. By optimizing the distribution and pressure of the water flow, the rotation of the nozzle is more stable and uniform, further expanding the water spraying range and improving the uniformity and coverage area of irrigation.

[0060] In addition, it should be noted that preferably, the nozzle 10 has a conical bottom surface 13, and a plurality of grooves 11 are annularly distributed on the conical bottom surface 13. The arrangement of the groove 11 causes the nozzle 10 to rotate under the action of the water flow. In the nozzle 10 of the present technical solution, some of the plurality of grooves 11 provided on the conical outer wall of the nozzle 10 are not distributed completely radially, but have a tangential component along the circumferential direction of the nozzle, so that the water flow can push the nozzle 10 to rotate. The above-mentioned part of the groove 11 with the tangential component is preferably uniformly distributed, so that the force pushing the nozzle 10 to rotate is more uniformly distributed.

[0061] It should be noted that, as shown in Figure 11 some of the grooves 11 have a straight guide groove 11a at the inner section and an inclined force receiving groove 11b at the outer section, and the straight guide groove 11a and the inclined force receiving groove 11b are in communication. Among them, the straight guide groove 11a is used to guide the water flow, and the inclined force receiving groove 11b guides the water flow to deviate at an angle, and through the reaction force of the water flow, the nozzle 10 is rotated.

[0062] In actual work process, as shown in Figure 6 when the spray head assembly 100 is connected to the external water pipe (or water supply equipment), the water flow enters the assembly and generates a certain water pressure. This water pressure first acts on the plug 60, pushing it to move upward and compress the return spring 80. However, more importantly, the water pressure simultaneously acts on the shaft 40 and the nozzle 10, making the whole body of the nozzle 10 lift up by a distance of 2-8 millimeters, thereby accurately opening the annular water outlet g.

[0063] With the opening of the annular water outlet g, the water flow is driven by the water pressure and sprayed outward along the pre-designed grooves 11 on the bottom wall of the nozzle 10. These grooves 11 not only guide the direction of the water flow, but also cooperate with the water pressure to make the nozzle 10 rotate under the reaction force of the water flow.

[0064] Moreover, there are partial grooves 11 with tangential components, whose direction is not entirely radial, but has a certain tangential component. This means that when the water flow passes through the grooves 11, it not only sprays outward in the radial direction, but also has a tangential component in the circumferential direction of the nozzle. This tangential component of the water flow will exert a tangential reaction force on the nozzle, thereby pushing the nozzle to rotate.

[0065] Finally, under the action of water pressure and the cooperation of the grooves 11, the nozzle 10 can rotate smoothly and efficiently. Moreover, the water lines sprayed by adjacent grooves 11 do not interfere with each other, and each maintains a clear and independent spraying path. This technical means not only ensures the uniform distribution of water flow, but also significantly expands the irrigation coverage of the sprinkler head assembly 100, making the irrigation area more comprehensive and uniform, effectively improving the irrigation efficiency and effect.

[0066] As shown in Figure 5 and Figure 6 , the base 20 is externally provided with a shell 101, and the lower end of the shell 101 is provided with an internal thread for connection with an external water supply device. The shell 101 not only provides additional structural support for the entire assembly, but also protects the internal components from the external environment. The lower end of the shell 101 is designed with an internal thread structure, so that the sprinkler head assembly 100 can be quickly, stably and tightly connected with the external water supply device.

[0067] Through this internal thread connection method, users can easily install the sprinkler head assembly 100 into the existing irrigation pipeline system without the need for additional fixing devices or complex connection processes. This not only improves the installation efficiency, but also ensures the stability and tightness of the water flow during transmission, effectively avoiding problems such as water leakage or unstable water flow. In addition, the design of the internal thread also allows users to flexibly replace or upgrade the sprinkler head assembly according to different irrigation needs, enhancing the versatility and adaptability of the equipment.

The above examples are only used to help understand the present application and the core idea. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the principle of the present application, the present application can be improved and modified in many ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
