Description

Technical Field

[0001] This utility model relates to the field of garden sprinkler technology, and specifically to a garden sprinkler with self-generating lighting function. Background Technology

[0002] Currently, lawn irrigation in landscaping is generally done in the early morning and evening because the temperature is relatively low, wind speed is low, and water evaporation is minimal during these times. This allows water to effectively penetrate deeper into the soil, reducing water waste. Existing garden sprinklers are typically used in conjunction with intelligent controllers, achieving autonomous irrigation through timed irrigation or sensor feedback.

[0003] Utility model patent CN204811342U discloses a rotary anti-clogging garden sprinkler, including a base and a rotating head rotatably mounted on the base. The rotating head has several water outlets and includes nozzles with connecting holes. The nozzles are detachably connected to the water outlets. The connecting holes have spherical walls. The sprinkler also includes a water outlet head, with the head extending out of the connecting hole and the tail of the water outlet head having a spherical connecting part located on the connecting hole. The water outlet head has a water outlet channel penetrating the head and tail, and the orientation of the water outlet channel can be changed by rotating the water outlet head. This prior art uses a detachable nozzle connection to the water outlet, so even if the nozzle is clogged, it can be quickly disassembled and replaced, avoiding the need to replace the entire unit after nozzle blockage. However, this garden sprinkler lacks lighting functionality, and in the early morning and evening, due to dim lighting, users cannot see the real-time irrigation status.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0019] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 6As shown, this utility model discloses a garden sprinkler with self-generated lighting function, comprising a base 1, on which are mounted a water inlet pipe 2, a lighting device 6, and a self-generated power device 8. The self-generated power device 8 is electrically connected to the lighting device 6 to provide power to the lighting device 6. A rotating head 3 is rotatably mounted on the base 1 and has multiple water outlet pipes 4. The water inlet pipe 2 is connected to the inlet end of the water outlet pipes 4, and the outlet end of the water outlet pipes 4 is equipped with a detachable spray nozzle 5. This configuration allows the lighting device 6 to illuminate the area around the sprinkler during irrigation in the dim light of early morning and evening, making it easier for users to see the real-time irrigation status and also serving as a landscape lighting effect. The self-generated power device 8 provides power to the lighting device 6, eliminating the need for an external power source and making it suitable for various scenarios with a wide range of applications.

[0021] The rotating head 3 is rotatably mounted on the base 1, which can drive multiple water outlet pipes 4 to rotate during irrigation, resulting in a wider irrigation range and better irrigation effect. The spray nozzle 5 is easy to install and remove. When the spray nozzle 5 is blocked, the nozzle can be quickly disassembled for cleaning or replacement, making it convenient to use.

[0022] Specifically, the garden sprinkler described in this utility model can achieve both the ability to see the water spraying process and the effect of landscape lighting while irrigating.

[0023] Preferably, the base 1 is made of zinc alloy and is integrally formed by mold.

[0024] Furthermore, the base 1 is provided with a cavity 9, and the self-generating device 8 is located inside the cavity 9. The cavity 9 is connected to the water inlet pipe 2 and the water outlet pipe 4. When the water inlet pipe 2 delivers water to the water outlet pipe 4, the water flow drives the self-generating device 8 to generate electricity, thereby providing power support for the lighting device 6. In this configuration, when water is flowing through the water inlet pipe 2 for irrigation, the water flow drives the self-generating device 8 to work, achieving the purpose of generating electricity from the water flow, and thus providing power support for the lighting device 6. Specifically, while irrigating, one can see the water spraying process and also enjoy the effect of landscape lighting.

[0025] Furthermore, the self-generating device 8 includes an impeller 15, a rust-proof magnetic ring 16, a sealing housing, a circuit board 19, and a coil 21. The impeller 15 is rotatably installed inside the cavity 9, and the rust-proof magnetic ring 16 is fixed to the inner wall of the impeller 15. The upper end of the sealing housing is fixed to the opening of the cavity 9, and the lower end of the sealing housing extends into the rust-proof magnetic ring 16. The circuit board 19 and the coil 21 are fixed inside the sealing housing, and the coil 21 is electrically connected to the circuit board 19, which is electrically connected to the lighting device 6. The rust-proof magnetic ring 16 and the coil 21 are arranged correspondingly. When the water inlet pipe 2 delivers water to the water outlet pipe 4, the water flow drives the impeller 15 to rotate the rust-proof magnetic ring 16. With this setup, when water is supplied through the inlet pipe 2 for irrigation, the water flow drives the impeller 15 to rotate, which in turn drives the anti-rust strong magnetic ring 16 to rotate. The coil 21 is subjected to magnetic lines of force, generating voltage, which is then output as DC voltage through the circuit board 19, thus illuminating the lighting device 6.

[0026] The sealed housing protects the circuit board 19 and coil 21 from water ingress. The rust-resistant magnetic ring 16 has a longer service life and will not rust due to contact with water.

[0027] Furthermore, the sealed housing includes a middle seat 18 and a cover plate 20. The cover plate 20 and the middle seat 18 are fixedly connected and form a receiving cavity. The circuit board 19 and the coil 21 are positioned vertically within the receiving cavity. An axial positioning assembly is provided between the middle seat 18 and the impeller 15. The cover plate 20 has a lead hole 24. The lead wire of the circuit board 19 passes through the lead hole 24 and is electrically connected to the lighting device 6. The lead hole 24 is sealed with silicone. This arrangement facilitates the routing of the lead wire of the circuit board 19, and the silicone seal of the lead hole 24 provides a waterproof effect.

[0028] Preferably, the cover plate 20 and the middle seat 18 are fixed to the opening of the cavity 9 by bolts, which is convenient for assembly.

[0029] Furthermore, the axial positioning assembly includes a positioning groove 25 located at the center of the lower surface of the base plate of the middle seat 18 and a positioning post 23 located at the center of the upper surface of the base plate of the impeller 15. The positioning post 23 is rotatably located within the positioning groove 25. This arrangement ensures that when the impeller 15 rotates, it rotates around the axis of the positioning post 23. With the cooperation of the positioning post 23 and the positioning groove 25, the impeller 15 and the middle seat 18 are coaxially and centrally positioned. When the impeller 15 drives the anti-rust strong magnetic ring 16 to rotate, the anti-rust strong magnetic ring 16 performs circumferential motion around the middle seat 18 and the coil 21.

[0030] Furthermore, an oil-impregnated bearing 17 is fitted onto the outer wall of the positioning post 23, and the outer wall of the oil-impregnated bearing 17 abuts against the inner wall of the positioning groove 25. This arrangement makes the impeller 15 rotate more smoothly and flexibly.

[0031] Among them, the oil-impregnated bearing 17 is located between the outer wall of the positioning column 23 and the inner wall of the positioning groove 25, which plays a certain positioning role and also prevents the impeller 15 from shifting left and right or shaking when it rotates.

[0032] Furthermore, a hemispherical protrusion 22 is provided at the center of the upper surface of the bottom plate of the cavity 9, and the top of the hemispherical protrusion 22 abuts against the center of the lower surface of the bottom plate of the impeller 15. This arrangement creates a rotational clearance between the bottom plate of the impeller 15 and the bottom plate of the cavity 9, preventing frictional damping between the impeller 15 and the bottom plate of the cavity 9 during rotation. Specifically, if the bottom plate of the impeller 15 abuts against the bottom plate of the cavity 9, the impeller 15 will rotate unevenly and inflexibly, affecting the power generation function.

[0033] Preferably, a hemispherical groove corresponding to the hemispherical protrusion 22 can be provided at the center of the lower surface of the impeller 15.

[0034] Furthermore, the cavity 9 is located in the middle of the water inlet pipe 2, and the cavity 9 is provided with a water inlet 10 and a water outlet 11. The water inlet pipe 2 is connected to the water inlet 10, and the water outlet 11 is connected to the water outlet pipe 4. The outer wall of the impeller 15 is distributed with multiple arc-shaped blades, which are correspondingly arranged with the water inlet 10. When the water inlet pipe 2 delivers water to the water outlet pipe 4, the water flow drives the arc-shaped blades to rotate the impeller 15. With this arrangement, when water is flowing through the water inlet pipe 2 for irrigation, the water flow enters the cavity 9, which can drive the arc-shaped blades to rotate the impeller 15.

[0035] The acute angle formed by the arc-shaped blade and the outer wall of the impeller 15 corresponds to the direction of the inlet 10.

[0036] Furthermore, the lighting device 6 includes an annular waterproof light strip 7 fixed to the base 1, with multiple LED beads spaced apart on the waterproof light strip 7; the base 1 has an annular structure and mounting holes corresponding to the multiple LED beads. This configuration, where the lighting device 6 consists of the annular waterproof light strip 7 and multiple LED beads spaced apart on the waterproof light strip 7, results in a longer service life. When the circuit board 19 outputs DC voltage, the annular waterproof light strip 7 and the multiple LED beads will illuminate.

[0037] The base 1 has an annular groove for assembling the annular waterproof light strip 7, which makes assembly convenient.

[0038] Preferably, the lighting beads are LED beads, and the lighting beads protrude through the mounting holes.

[0039] Furthermore, the multiple water outlet pipes 4 are evenly distributed on the outer wall of the rotating head 3, and each water outlet pipe 4 has an upward-curving bend in the middle. With this arrangement, when water is supplied through the inlet pipe 2 for irrigation, the water flow is diverted to the multiple water outlet pipes 4, and then guided by the bend before rotating and spraying water, resulting in a better irrigation effect.

[0040] Preferably, there are three water outlet pipes 4, and the included angle between two adjacent water outlet pipes 4 is 120 degrees.

[0041] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims. All of these forms are within the scope of protection of the present utility model.
