Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment, and in particular to a rotary nozzle for connecting water pipes. Background Technology

[0002] Existing rotary sprinklers typically generate rotational power through an asymmetrical structure of the spray trough, thereby spraying water onto the surrounding plants. However, during spraying, issues arise such as excessively large or unevenly sized water droplets. Large droplets may damage delicate crops, while uneven droplets result in inconsistent water distribution among plants, leading to varying growth rates. The cause of these excessively large or uneven droplet sizes is attributed to the slow rotational speed of the rotating component. Currently, considering the structure of rotary sprinklers, the only way to increase the rotational speed is to increase the water pressure. However, excessive water pressure during irrigation may knock over immature seedlings, causing them to die. Furthermore, if the rotary sprinkler is manufactured to a small size, it may loosen under high water pressure, thus failing to effectively increase the rotational speed. Therefore, existing rotary sprinklers still have structural defects that require improvement. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems in the prior art and to provide a rotating nozzle that sprays evenly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rotating nozzle includes a base, a spraying element, a vane, and a positioning unit. The base is used to connect a water pipe and has a chamber with a water outlet. The spraying element is disposed on the base and communicates with the water outlet. The spraying element includes an annular wall surrounding the water outlet, with at least one through groove formed within the annular wall. A spraying part is provided at the upper part of the through groove, and a positioning part is provided at the top of the spraying part. The spraying part has at least one spraying groove communicating with the through groove, and at least a portion of the spraying groove extends circumferentially around the spraying part. The vane is connected to at least one end of the spraying groove. The positioning unit is connected to the base and is used to position the spraying element on the base.

[0006] The positioning unit includes a support member and a positioning member. The support member is connected to the base. The positioning member is connected to the support member and has a positioning hole for the positioning part to pass through. The support member has at least one branch that connects to the positioning member and one side of the base.

[0007] The support member has symmetrical branches on both sides.

[0008] The support member is provided with a support hole through which the positioning member extends.

[0009] Each of the winglets and spray slots is provided in twos.

[0010] The branch portion has an inner end facing the spraying component, an outer end opposite to the inner end, and a connecting surface connecting the inner end and the outer end, the connecting surface gradually narrowing from the outer end toward the inner end.

[0011] The branch has an inner end facing the spraying element, an outer end opposite to the inner end, and a connecting surface connecting the inner and outer ends. This connecting surface tapers from the center towards the outer and inner ends, respectively. This design allows a portion of the water sprayed by the spraying element to flow closely along the surface of the branch, allowing the water flow close to the branch to recombine before being sprayed outward, thus reducing the blind angle of spraying caused by the branch obstruction.

[0012] The base also includes a connecting part and a water outlet part. The connecting part has the chamber inside, and the water outlet part is connected to the connecting part and has the water outlet.

[0013] The connecting part has a threaded section formed on its outer surface.

[0014] The connecting part has a threaded section formed on its inner surface.

[0015] In this invention, when water is sprayed from the spray trough, it generates circumferential rotational force on the spraying component, thereby driving the spraying component to rotate circumferentially. The blades are connected to the spraying part and extend outward to increase the lever arm of the spraying component in contact with the water, thereby increasing the torque to generate greater rotational force.

[0016] Compared with the prior art, the beneficial effects achieved by the technical solution of this utility model are:

[0017] This invention features at least one wing on the spraying part, which increases the lever arm of the spraying part in contact with water, thereby increasing the torque to generate greater rotational power. Compared with the prior art, it exhibits faster and more stable rotation under the same water pressure, and the sprayed water forms finer droplets, thus allowing for more even spraying when irrigating plants.

Detailed Implementation

[0026] To make the technical problems, technical solutions and beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] See Figure 1 The rotating nozzle of this embodiment is suitable for connecting a water pipe 5 and includes a base 1 suitable for connecting the water pipe 5, a spraying element 2 disposed on the base 1, two blades 3 connecting the spraying element 2, and a positioning unit 4 connected to the base 1 and used to position the spraying element 2 on the base 1.

[0029] In this embodiment, the diameter, length and material of the water pipe 5 are not limited, and the user can choose the water pipe that meets their needs according to their own requirements.

[0030] The base 1 includes a connecting portion 11 extending around a first axis Y and defining a chamber 110, and a water outlet portion 12 connecting to the connecting portion 11 and defining a water outlet 120. The connecting portion 11 has a threaded section 111 formed on its outer surface, suitable for threading a water pipe 5 equipped with a threaded connector. By engaging the threaded section 111 with the threaded connector, the risk of the water pipe 5 detaching from the connecting portion 11 can be reduced when the water pressure is increased.

[0031] See Figure 1 and Figure 2The spraying element 2 includes an annular wall 21 surrounding the outlet 120 and defining a through groove 210 that communicates with the chamber 110, a spraying portion 22 connecting to the annular wall 21, and a positioning portion 23 formed at the top of the spraying portion 22. The spraying portion 22 has two spraying channels 220 respectively communicating with the through groove 210. Each spraying channel 220 has a first end 221 and a second end 222 spaced apart from each other along a first circumferential direction R surrounding the spraying portion 22. Two blades 3 are respectively connected to the first ends 221 of the two spraying channels 220. In this embodiment, the length of the first end 221 parallel to the first axis Y is greater than the length of the second end 222 parallel to the first axis Y, so that the spraying channel 220 increases its component toward the first circumferential direction R due to the increase in lever arm. The spraying element 2 is preferably designed as an annular shape, and the top of the spraying portion 22 is provided with several grooves to reduce the weight of the spraying portion 22, thereby reducing the weight of the spraying element 2. Furthermore, in this embodiment, the positioning part 23 is a protruding post protruding from the spraying part 22. However, in the implementation of this utility model, the positioning part 23 is not limited to the shape of a protruding post, as long as it can reliably match the shape of the positioning unit 4, so that the spraying part 2 can be reliably positioned in a rotatable state.

[0032] The positioning unit 4 includes a support member 42 connected to the base 1 and a positioning member 41 connected to the support member 42. The positioning member 41 has a positioning hole 410 through which the positioning part 23 passes. The diameter of the positioning hole 410 is slightly larger than the diameter of the protrusion, so that when the positioning part 23 is positioned through the positioning hole 410, the spraying part 2 can still rotate. The support member 42 has two branches 421 spaced apart along a second axis X perpendicular to the first axis Y and respectively connected to the opposite sides of the positioning member 41 and the base 1, for supporting the positioning member 41 on the spraying part 2. In this embodiment, by setting two branches 421, the embodiment is symmetrical about the first axis Y, which can maintain the balance of the center of gravity of the embodiment under greater water pressure, thereby improving the stability of the embodiment during installation.

[0033] See Figure 3 and Figure 4In this embodiment, after connecting the water pipe 5, water flows from the chamber 110 of the base 1 through the outlet 120 to the spraying member 2. Then, the water flows through the through-slot 210 of the spraying member 2 to the spraying groove 220, and finally sprays from each spraying groove 220 in a direction away from the first axis Y, simultaneously generating a thrust along the first circumferential direction R on the spraying member 2, thereby causing the spraying member 2 to rotate around the first axis Y along the first circumferential direction R. At this time, since the two blades 3 are respectively disposed on the spraying part 22 and connected to the first ends 221 of the two spraying grooves 220, the water sprayed from the two spraying grooves 220 also contacts the two blades 3. Compared to the case without the blades 3, the blades 3 can be used to increase the lever arm of the sprayer 2 in contact with the water, thereby increasing the torque to generate greater rotational power. Thus, under the same water pressure, this embodiment can exhibit a faster and more stable rotational speed, thereby making the water sprayed from the spray trough 220 into finer droplets, so that the water can be sprayed more evenly when irrigating plants.

[0034] like Figure 4 As shown, each branch 421 has an inner end 422 facing the spray element 2, an outer end 423 opposite to the inner end, and a connecting surface 424 connecting the inner end 422 and the outer end 423. The connecting surface 424 gradually tapers from the outer end 423 towards the inner end 422. It should be noted that, in this embodiment, the tapering design of the connecting surface 424 reduces the obstruction area facing the spray groove 220, thereby avoiding affecting the water output.

[0035] Furthermore, under long-term use, some dust will accumulate on the spray element 2, which will affect the water output of the spray element 2. Therefore, the support member 42 is provided with a support hole 425 for the positioning member 41 to pass through, so that the positioning member 41 can be freely removed from the support member 42. In this way, the spray element 2 can also be removed from the base 1, and the user can clean the spray element 2 and then reinstall it back on the base 1.

[0036] It is worth mentioning that while metal materials can be used in this embodiment, plastic is preferred. Plastic is lightweight, allowing for faster rotation speeds when used with water. Furthermore, since this embodiment is intended for long-term use in humid environments, the advantage of plastic over metal is that it does not rust, thus extending the lifespan of this embodiment.

[0037] Example 2

[0038] See Figure 5The structure of Embodiment 2 is largely the same as that of Embodiment 1, but the difference lies in that the connecting surface 424 tapers from the center towards the outer end 423 and the inner end 422 respectively, making the horizontal cross-section of the branch 421 elongated ellipse. This embodiment is based on Embodiment 1 and further optimizes the shape of the branch 421. This allows the water to flow along the connecting surface 424 and change direction when it comes into contact with the connecting surface 424 during spraying, reducing the impact of water being blocked by the branch 421 and thus improving the spraying efficiency of Embodiment 2.

[0039] Example 3

[0040] See Figure 6 The structure of Embodiment 3 is largely the same as that of Embodiment 2, but the difference is that each vane 3 is connected to the second end 222 of the spray trough 220. In Embodiment 3, water flows through the first end 221 and drives the spray section 22 to rotate about the first axis Y. At this time, some water adjacent to the spray section 22 will flow around the spray section 22 along the first circumferential direction R due to inertia. When the water flowing around the spray section 22 contacts the vane 3, it also applies a thrust to the vane 3. Combined with the increase in the lever arm, this increases the rotational speed of the spray member 2, making the water sprayed from the spray trough 220 appear as finer water droplets.

[0041] Example 4

[0042] See Figure 7 The structure of Embodiment 4 is largely the same as that of Embodiment 1, but the difference is that the support member 42 has only one branch 421 connecting the positioning member 41 and one side of the base 1. Embodiment 4 is applied to plant seedlings or small plant species, and therefore is preferably manufactured in a style with a height of three to five centimeters. With the reduced size of Embodiment 4, the maximum water pressure that can be withstood is also reduced, and the support requirement for the branch 421 of the support member 42 is also reduced. Therefore, Embodiment 4 reduces the number of branch 421, thereby reducing the volume to suit the applicable plant species while maintaining normal operation.

[0043] For example, when planting seedlings, farmers can choose to use Embodiment 4 for irrigation. The smaller size of Embodiment 4 not only saves space but also reduces the water output, lowering the risk of seedlings being washed away during irrigation and increasing their survival rate. In another scenario, urban farming is popular today, with office workers enjoying using their home spaces, such as balconies, to grow plants and relieve stress. However, balcony space is usually limited. To maximize usable space, office workers can choose Embodiment 4 for their irrigation devices. Its lightweight design allows for greater flexibility in utilizing balcony space.

[0044] In summary, the rotary nozzle of this invention, by connecting a vane 3 to the extended end of the spray groove 220, increases the lever arm of the spray component in contact with water, thereby increasing the torque and generating greater rotational power. This allows the present invention to exhibit a faster rotational speed under the same water pressure compared to existing technologies, thereby increasing the uniformity of spraying. Therefore, it effectively achieves the purpose of this invention.

[0045] Furthermore, the design of the branch's connecting surface tapering from the center towards the outer and inner ends respectively allows some of the water sprayed by the spray unit to flow closely along the surface of the branch, allowing the water flow close to the branch to combine and then spray outward, thus reducing the blind angle of spraying caused by the branch obstruction.

[0046] The above are merely embodiments of this utility model and should not be construed as limiting the scope of implementation of this utility model. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the patent specification shall still fall within the scope of this utility model patent.
