Description

Technical Field

[0001] This invention relates to the field of sprinkler irrigation equipment technology, and in particular to an adjustable sprinkler head with controllable spray pattern. Background Technology

[0002] Sprinkler irrigation technology is commonly used for the routine maintenance of landscape lawns or special plants. Common sprinkler heads are generally divided into rotary sprinklers, fixed sprinklers, and orifice sprinklers. Rotary sprinklers include rocker arm sprinklers, impeller sprinklers, and reaction sprinklers, while fixed sprinklers include refraction sprinklers and slot sprinklers. The working area of ​​the above-mentioned sprinkler heads is basically a circle with a fixed radius, which cannot precisely irrigate irregular plots or plots with complex curved boundaries. Especially for landscape lawns, which are usually located next to roads, it is difficult for commonly used sprinklers to guarantee that the entire landscape lawn is irrigated without spraying water onto the road. Therefore, there is currently no suitable sprinkler head that can achieve controllable spray pattern. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable spray head with controllable spray shape, which can achieve controllable spray shape by changing the adjustable unit of the set height and set shape spray holes; by adjusting the height of the adjusting screw, the pressure in the spray pipe is finely adjusted, and then the spray position of each spray hole is finely adjusted, so as to further accurately control the spray shape.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: an adjustable sprinkler head with controllable spray shape, comprising a pipe assembly and a nozzle assembly, wherein the pipe assembly is arranged vertically and both ends of the pipe assembly are detachably connected to a water inlet pipe and a nozzle assembly, respectively.

[0005] The nozzle assembly includes a nozzle base, a baffle structure is horizontally provided inside the nozzle base, a baffle threaded hole is provided in the center of the baffle structure, a plurality of stepped holes are provided in a ring around the baffle structure, and an adjustable unit is provided vertically on the stepped holes.

[0006] The adjustable unit is provided with a pressure cover at the top, and a fastening bolt is provided vertically in the center of the pressure cover, which passes through the interior of the fastening bolt and is spirally connected to the threaded hole of the baffle plate.

[0007] The adjustable unit includes a nozzle with nozzles of different shapes, and a height-adjustable screw on the top of the nozzle.

[0008] Preferably, the nozzle has a positioning surface on its outer side that matches the stepped hole.

[0009] Preferably, the adjusting screw includes a smooth rod structure, the bottom of the smooth rod structure is provided with a water-passing inclined surface, the smooth rod structure is provided with an external thread, and the top of the nozzle is provided with an internal thread that matches the external thread on the smooth rod structure.

[0011] Preferably, the pressure cap is provided with a pressure cap countersunk hole at the corresponding position of each nozzle.

[0012] Preferably, the countersunk hole of the pressure cap is provided with a sealing gasket groove.

[0013] Preferably, a shaped sealing ring is provided between the stepped hole and the adjustable unit.

[0014] Preferably, the nozzle holder has an external hexagonal edge.

[0017] The beneficial effects of this invention are:

[0018] 1. The tube assembly and nozzle assembly of this solution are detachably connected, which facilitates the replacement of tube assemblies of different heights and enables free adjustment of the height of the nozzle assembly, thereby adapting to the needs of different spray patterns.

[0019] 2. The fastening bolts in this design are screwed into the threaded holes of the retaining plate. Tightening or loosening the fastening bolts facilitates the replacement of the adjustable unit.

[0020] 3. This solution achieves precise spray positions for each nozzle by replacing the adjustable units with different set heights and shapes, thus collectively forming the desired spray pattern. By replacing the adjustable units with nozzles of different set heights and shapes, the spray pattern can be controlled.

[0021] 4. This solution allows for fine-tuning of the pressure inside the nozzle by adjusting the height of the adjusting screw, which in turn allows for fine-tuning of the ejection position of each nozzle, further enabling precise control of the spray pattern.

[0022] 5. The nozzle of this design has a positioning surface on the outside that matches the stepped hole, which facilitates the quick positioning of the nozzle in the stepped hole and the contact limiting between each nozzle.

[0037] The present invention will now be described in further detail with reference to the embodiments and the accompanying drawings.

[0038] This invention discloses an adjustable sprinkler head with controllable spray pattern. For example... Figure 1 As shown, the embodiment includes a pipe assembly 2 and a nozzle assembly 1. The pipe assembly 2 is vertically arranged, and its two ends are detachably connected to a water inlet pipe and the nozzle assembly 1, respectively. The detachable connection between the pipe assembly 2 and the nozzle assembly 1 facilitates the replacement of pipe assemblies 2 at different heights, allowing for free adjustment of the height of the nozzle assembly 1, thereby adapting to the needs of different spray patterns.

[0039] like Figure 2 , 3 As shown, the nozzle assembly 1 includes a nozzle seat 11, within which a baffle structure 112 is horizontally arranged. The baffle structure 112 has a central threaded hole 114, and multiple stepped holes 113 are arranged circumferentially around its periphery. These stepped holes 113 together form a stepped hole array. An adjustable unit 12 is vertically arranged on each stepped hole 113. Water from the inlet pipe passes sequentially through the pipe assembly 2 and the nozzle seat 11 into the adjustable unit 12.

[0040] The adjustable unit 12 is provided with a pressure cap 13 on top, and a fastening bolt 14 is vertically provided in the center of the pressure cap 13, passing through its interior. The fastening bolt 14 is screwed into the threaded hole 114 of the retaining plate. The adjustable unit 12 can be easily replaced by tightening or loosening the fastening bolt 14.

[0041] like Figure 4 As shown, the adjustable unit 12 includes a nozzle 121, on which nozzles 122 of different shapes are formed. The nozzles 122 can be chamfered square holes, round holes, star-shaped holes, or other irregularly shaped holes. By changing the adjustable unit 12 with different set heights and shapes of nozzles 122, the precise spray positions of each nozzle 122 can be achieved, thus collectively forming the desired spray shape. By changing the adjustable unit 12 with different set heights and shapes of nozzles 122, the spray shape can be controlled.

[0042] The nozzle 121 is equipped with a height-adjustable adjusting screw 123 at the top. By adjusting the height of the adjusting screw 123, the pressure inside the nozzle 121 can be finely adjusted, thereby finely adjusting the ejection position of each nozzle 122 and further precisely controlling the spray shape.

[0043] The nozzle 121 is provided with a positioning surface 124 on the outside that matches the stepped hole 113, which facilitates the nozzle 121 to be quickly positioned in the stepped hole 113 and to make contact and limit the nozzles 121.

[0044] like Figure 5 As shown, the adjusting screw 123 includes a smooth rod structure 1231. The bottom of the smooth rod structure 1231 has a water-passing inclined surface 1233, which can be smooth or have a guide groove machined on it as needed. The smooth rod structure 1231 has an external thread, and the top of the nozzle 121 has an internal thread that matches the external thread on the smooth rod structure 1231. The top of the smooth rod structure 1231 has a slot 1232, facilitating the adjustment of the height of the adjusting screw 123 by inserting a flathead tool into the slot 1232. The slot 1232 can also be replaced with an internal hexagonal socket.

[0045] like Figure 6 As shown, the pressure cap 13 has countersunk holes 131 at corresponding positions of each nozzle 121, allowing a flathead tool to directly enter the slot 1232 for adjustment without disassembling the pressure cap 13. This facilitates adjustment when the nozzle 121 is filled with water and water is spraying from each nozzle 122 under pressure, enabling precise control of the spray pattern. The countersunk holes 131 are equipped with sealing gasket grooves 132.

[0046] like Figure 7 As shown, a shaped sealing ring 15 is provided between the stepped hole 113 and the adjustable unit 12 to seal the stepped hole 113 and the adjustable unit 12 and prevent water leakage.

[0047] like Figure 3 As shown, the nozzle holder 11 is provided with an external hexagon 111, which makes it easy to tighten with a wrench.

[0048] like Figure 8 As shown, the pipe assembly 2 includes a pipe connector 21, the top of which is provided with an external thread, and the nozzle seat 11 is provided with an internal thread that matches the external thread on the pipe connector 21. The bottom of the pipe connector 21 is provided with a pipe head limiting protrusion 23, and the pipe connector 21 is also provided with a union nut 22 that cooperates with the pipe head limiting protrusion 23 and is spirally fixedly connected to the water inlet pipe.

[0049] During assembly, first remove the nozzle holder 11, place the irregular sealing ring 15 in the stepped hole 113, and place the adjustable unit 12 with the set height and shape of the spray holes 122 in the stepped hole 113. Align the countersunk hole 131 of the pressure cap 13 with the adjusting screw 123 of the adjustable unit 12, and screw the fastening bolt 14 with the threaded hole 114 of the baffle plate. Then, water from the inlet pipe passes through the pipe assembly 2 and the nozzle holder 11 into the adjustable unit 12, and water sprays from the spray holes 122. For adjustable units 12 requiring fine-tuning, use a flathead tool to directly access the flathead groove 1232 through the countersunk hole 131 of the pressure cap to adjust the height of the adjusting screw 123. Fine-tune the pressure within the spray pipe 121, and then fine-tune the spray position of each spray hole 122 to further precisely control the spray shape.
