Description

Technical Field

[0001] The present invention relates to the technical field of irrigation equipment, in particular to an irrigation timer whose switch is controlled by a reduction box. Background Art

[0002] Irrigation is an agricultural technique that artificially regulates water resources to meet the growing water needs of crops. As a key component of agricultural production, modern irrigation systems have evolved from traditional flooding to precise, efficient, and intelligent systems. Water-saving technologies such as drip and sprinkler irrigation deliver water directly to crop roots through a network of pipes. Combined with soil moisture sensors and automated control systems, they enable on-demand water supply.

[0003] As a key control device in modern agricultural water-saving irrigation systems, irrigation timers precisely control water supply timing and volume through pre-set programs, effectively addressing issues such as low manual operation efficiency and water waste. Their core function is to intelligently adjust irrigation cycles based on crop needs, avoiding operations during peak evaporation periods, achieving water savings of over 30%. They also support multi-zone time-sharing control to adapt to different crop growth characteristics and significantly reduce labor costs. Existing irrigation timers typically use springs as their power source. These products generally suffer from drawbacks such as a short lifespan (typically 2-3 years) due to elastic fatigue and high shock during opening and closing. Electric models controlled by solenoid valves, on the other hand, suffer from high power consumption and high cost. With the development of precision agriculture, the market urgently needs a new timing control solution that combines mechanical reliability, ease of operation, and long-term durability.

[0004] Therefore, it is necessary to provide an irrigation timer that controls the switch through a reduction gear box to solve the above technical problems. Summary of the Invention
