[0002] Against the backdrop of increasingly strained global water resources, water conservation has become a key measure to alleviate water shortages and achieve sustainable development. Whether in agricultural irrigation, industrial production, or daily water use, efficient and precise water-saving regulation is of great significance for the rational use of water resources and the reduction of energy consumption.
[0003] According to patent document CN221347941U, a water-saving control device is disclosed, including a water pipe, a box, and a slot. The box is fixedly connected to the outside of the water pipe.

This manual adjustment method has many drawbacks: on the one hand, manual operation is inefficient, making it difficult to adjust drainage volume in real time and quickly according to actual water demand, which can easily lead to water waste or insufficient water supply; on the other hand, the accuracy of manual adjustment is greatly affected by the operator's experience and condition, resulting in significant differences in the results of different operators, making it impossible to guarantee the consistency and stability of water-saving control.
