The nozzle housing can rotate under water pressure. The upper end of the shaft passes through the nozzle housing into the cavity and is fixedly connected to the cup-shaped metal body inside the cavity. The fluid damping medium fills the voids inside the cavity. The fluid damping medium binds the shaft, the cup-shaped metal body, and the nozzle housing to reduce and stabilize the rotational speed of the nozzle housing under water pressure. The damped rotating ray nozzle cleverly utilizes the viscosity of the fluid damping medium filling the cavity to reduce and stabilize the rotational speed of the nozzle housing under water pressure.

Detailed Implementation

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0025] 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.

[0026] like Figure 1 As shown, the lifting sprinkler head assembly 100 is an irrigation device. This technical solution mainly introduces its core component, the damped rotating ray sprinkler head 101. This sprinkler head, through its unique structural components and built-in fluid damping medium, can achieve slow and stable rotation under high-pressure water flow, thereby ensuring a more uniform water coverage area and effectively improving irrigation results. Details will be elaborated below.

[0027] like Figures 2 to 6 As shown, the damped rotating ray sprinkler head 101 includes a sprinkler housing 10 with an internal cavity 11, a shaft 20, a bowl-shaped metal body 30, and a fluid damping medium. The sprinkler housing 10 has an internal cavity 11, which provides space for the internal components of the sprinkler. Under water pressure, the sprinkler housing 10 can rotate, thereby driving the water flow to be sprayed out in the form of a rotating ray, achieving a more uniform irrigation effect.

[0028] The shaft 20 is a key component of the nozzle. Its upper end passes through the nozzle housing 10 and extends into the cavity 11, where it is fixedly connected to the bowl-shaped metal body 30. This connection method ensures a strong bond between the shaft 20 and the bowl-shaped metal body 30, allowing the nozzle to maintain stable structural performance during rotation. The bowl-shaped metal body 30, located within the cavity 11, provides support and fixation, while its connection with the shaft 20 also provides stable power transmission for the nozzle's rotation.

[0029] It is important to emphasize that the fluid damping medium is a key innovative technology in this solution. It fills the voids inside the cavity 11 and bonds the shaft 20, the bowl-shaped metal body 30, and the nozzle housing 10. This bonding effect not only enhances the stability of the internal components of the nozzle, but more importantly, the fluid damping medium generates a damping effect under water pressure. Through this damping effect, the rotational speed of the nozzle housing 10 is reduced and maintained within a stable speed range. This technical effect allows the nozzle to achieve slow and stable rotation even under high-pressure water flow, thus ensuring a more uniform water coverage area and effectively improving irrigation efficiency.

[0030] More specifically, the nozzle housing 10 includes a conical bottom shell 12 and a cover 13. A conical groove 121 is formed inside the conical bottom shell 12, and the cover 13 is precisely connected to the top of the conical groove 121 by a tight fit, thereby forming a sealed and functional cavity 11. This structure not only provides installation space for other components inside the nozzle, but also ensures the stability and sealing of the nozzle under water pressure.

[0031] In addition, the outer wall of the conical base shell 12 is designed with multiple water flow grooves 122, which play a key role when water flows through. The water flow grooves 122 not only guide the direction of the water flow, but also generate rotational force under the impact of the water flow, so that the nozzle housing 10 can rotate smoothly under water pressure, thereby achieving a more uniform water spray effect.

[0032] Based on the above technical means, the kinetic energy of the water flow is converted into the rotational power of the nozzle. At the same time, the optimized layout of the water flow groove 122 ensures the stable rotational performance of the nozzle under different water pressure conditions.

[0033] Furthermore, a support assembly 40 and a sealing assembly 50 are provided inside the cavity 11 of the nozzle housing 10 to ensure stable operation and sealing performance of the nozzle. The main function of the support assembly 40 is to provide a solid support for the upper end of the shaft 20, ensuring that it maintains precise positioning and stability during rotation. This assembly consists of an upper support member 41 and a lower support member 42, which work together to provide a comprehensive support structure for the shaft 20.

[0034] The sealing assembly 50 is responsible for ensuring the internal sealing of the nozzle and preventing leakage of damping fluid. It consists of an upper seal 51 and a lower seal 52, both of which have central holes that fit tightly with the shaft 20 to form a sealing structure. The upper support 41 is installed below the upper seal 51, while the lower support 42 is located above the lower seal 52. This layout not only optimizes space utilization but also allows the support assembly 40 and the sealing assembly 50 to work closely together, ensuring that the shaft 20 remains stable during rotation and effectively preventing water leakage from the gap between the shaft and the nozzle housing, thereby ensuring the efficient operation and long-term reliability of the nozzle.

[0035] Preferably, a sealing ring 60 is provided between the upper support member 41 and the cover portion 13. This further enhances the sealing performance inside the nozzle, ensuring that the damping fluid will not leak from the gap between the upper support member 41 and the cover portion 13 under high-pressure water flow. It also ensures effective water flow and spraying effect under high pressure.

[0036] Furthermore, preferably, such as Figure 5 As shown, several holes are formed on the upper support member 41. These holes provide channels for the flow of the fluid damping medium. During the operation of the nozzle, the fluid damping medium circulates through these holes in the cavity 11 of the nozzle housing 10, thereby ensuring that the damping medium is evenly distributed in various key parts inside the nozzle, including the shaft 20, the bowl-shaped metal body 30, and the nozzle housing 10.

[0037] This technology not only helps the damping medium to fully exert its role in reducing and stabilizing the nozzle rotation speed, but also effectively avoids the unstable operation of the nozzle caused by the local accumulation of damping medium, further optimizing the rotation performance of the nozzle and the uniformity of water spray.

[0038] It should also be noted that by reasonably optimizing and arranging the number and position of the holes, the flow path and flow rate of the damping medium can be precisely controlled, thereby achieving precise adjustment of the nozzle rotation speed and enabling it to maintain an ideal operating state under different water pressure conditions.

[0039] The shaft 20 is passed through the central hole of the bowl-shaped metal body 30 by a stamping process, thus fixing the bowl-shaped metal body 30 and the shaft 20 together. The stamping process creates a strong mechanical connection between the metal parts, ensuring that the bowl-shaped metal body 30 and the shaft 20 will not loosen or detach under the rotation of the nozzle and the impact of water flow, thereby improving the overall structural strength and reliability of the nozzle. Furthermore, the stamping process precisely fixes the bowl-shaped metal body 30 in the predetermined position of the shaft 20, ensuring coaxiality and concentricity between the two. This high-precision connection helps reduce vibration and wobbling during rotation, making the nozzle rotation smoother.

[0040] Preferably, in this technical solution, the water pressure range is between 1.7 bar and 3.8 bar. This allows the nozzle to rotate slowly and stably. The viscous properties of the fluid damping medium can effectively reduce the rotation speed of the nozzle housing under high-pressure water flow, keeping it within a reasonable range and preventing excessive rotation due to excessive water pressure, thereby ensuring a more uniform water spray coverage area.

[0041] Moreover, the sprinkler head achieves optimal irrigation results within a water pressure range of 1.7 bar to 3.8 bar. As water flows through the water flow grooves on the outer wall of the sprinkler head housing 10, a stable rotational force is generated, allowing the sprinkler head to rotate smoothly under water pressure, thereby achieving uniform water spray coverage.

[0042] This technology ensures that plants or crops receive a uniform water supply during irrigation, avoiding localized over-wetting or under-wetting caused by uneven water spraying, thereby improving irrigation efficiency and plant growth quality.

[0043] The inner wall of the conical bottom shell 12 and the outer peripheral wall of the cover 13 are fixedly connected by a first inverted snap structure. Specifically, as follows: Figure 7 As shown, the cover 13 consists of a base plate 131 and a peripheral sidewall 132, with an annular rib 133 on the outer side of the peripheral sidewall 132. Correspondingly, an annular groove 123 is formed on the inner side of the upper end of the conical bottom shell 12. The first inverted structure includes the aforementioned annular rib 133 and annular groove 123. During assembly, the annular rib 133 is pressed into the annular groove 123, thereby achieving a tight connection between the cover 13 and the conical bottom shell 12. This inverted structure not only ensures the firmness of the connection but also improves the overall sealing performance of the nozzle.

[0044] To further optimize the connection, the annular sidewall 132 is designed to taper inwards, while the upper opening diameter of the conical base shell 12 increases towards the top, echoing and matching the downward taper of the annular sidewall. This technique not only allows the cover 13 to fit more tightly into the conical base shell 12 but also enhances the stability and sealing of the connection, ensuring that the fluid damping medium and other components inside the nozzle do not leak under high-pressure water flow. With this technique, the nozzle maintains high stability and reliability during operation, while extending its service life.

[0045] like Figure 4 As shown, Figure 4As shown, the inner wall of the conical bottom shell 12 is fixedly connected to the outer peripheral walls of the upper support member 41 and the lower support member 42 through an undercut structure. Specifically, the connection between the conical bottom shell 12 and the upper support member 41 adopts a second undercut structure, while the connection with the lower support member 42 adopts a third undercut structure. Both undercut structures can preferably adopt the specific technical means of the first undercut structure, that is, a firm connection is achieved through the tight fit of the ribs and grooves.

[0046] A further optimization involves the inner circumferential sidewall of the conical base shell 12 being continuously inclined, with the corresponding inclined sideswalls of the upper support member 41 and lower support member 42, thus matching and fitting with the inner circumferential sidewall of the conical base shell 12. This fit of the inclined surfaces effectively reduces gaps between components, significantly improving the sealing performance inside the nozzle. Furthermore, the matching of the inclined surfaces between components ensures a uniform distribution of stress at component joints, preventing stress concentration and ensuring stable and efficient nozzle operation.
