Description

Technical Field

[0001] The utility model belongs to the technical field of irrigation sprinklers, and particularly relates to a solar energy-saving irrigation sprinkler device based on the uniform self-diffusion by the impact of an aspherical mirror. Background Technique

[0002] Irrigation is a form of watering to supplement the soil moisture of garden green spaces and meet the water requirements of plants. The irrigation system should pay attention to coordinating with the water requirements of plants and consider water conservation, energy conservation, convenience and practicality. In some garden green space irrigation systems, garden workers need to drag hoses around to water the flowers and plants. Moreover, during the irrigation process, water will flow onto the road, wasting a lot of water resources. Manual watering is not only uneven but also inconvenient. Therefore, it is necessary to adopt a water-saving, energy-saving, convenient, automatic and uniformly wetting method for irrigation. In addition, in some garden green space irrigation systems, an automatic sprinkler irrigation system is used. However, the existing irrigation sprinklers are rotary sprinklers, which eject one or two streams of water from one side or both sides of the sprinkler, and then use the centrifugal force of water through high-speed rotation to throw the water out to increase the irrigation area. However, due to the single water path of the irrigation sprinkler, the electrodes located inside the sprinkler are soaked in water for a long time, resulting in shortened service life and increased replacement frequency. Moreover, the rotation process causes uneven irrigation, and the irrigation range is not easy to control, which may cause adverse effects on other nearby animals and plants. For example, the benches for rest beside the sidewalks in the garden green spaces and the passing pedestrians will be splashed by the ejected water. Content of the Utility Model

That is, the main purpose of the diffused aspherical mirror 7 is to divert the flow, and then the water is evenly sprayed around.
