[0003] Garden irrigation is one of the important measures to maintain the healthy growth of green land. Traditional garden sprinkler devices mostly use fixed-height ground-inserted or standpipe sprinklers for irrigation. The height of these sprinklers is usually fixed, generally between 0.5 meters and 1.2 meters. However, this fixed-height design has certain limitations.

[0004] Firstly, fixed-height irrigation devices have poor adaptability; due to the variety of vegetation, different plants have different water needs during their growth cycle, and their heights also change. Fixed-height sprinklers cannot meet the irrigation needs of plants of different heights, especially for green areas with multi-level vegetation structure (such as the coexistence of herbaceous plants and shrubs).

[0005] Secondly, fixed-height irrigation devices are difficult to adjust; once installed, most sprinklers on the market need to be re-dug or replaced with longer standpipes to adjust their height, which is not only time-consuming and labor-intensive, but also may damage the original landscape design.

[0006] Thirdly, fixed-height irrigation devices are inefficient; fixed-height sprinklers may not provide sufficient irrigation to some areas in the face of large terrain undulations or obstacles, affecting the overall irrigation effect.

[0007] In recent years, with the development of technology, some sprinkler systems with automatic adjustment function have appeared. For example, the existing garden greening efficient purification dust falling device adjusts the height of the sprinkler through a motor-driven threaded rod, improving the adaptability and irrigation efficiency of the device. However, most of these devices still need to be manually operated or rely on complex mechanical structures, and cannot completely solve the above technical problems.
