[0002] Drip irrigation is a water-saving irrigation technology. Through a low-pressure pipeline system, water, fertilizers and other nutrients are directly transported to the vicinity of the crop roots in the form of water droplets or thin streams to achieve precise irrigation. This method can greatly reduce the losses of water evaporation and deep percolation, improve the water resource utilization efficiency, and help control the soil humidity and improve the crop growth environment, so as to achieve the purpose of increasing production and protecting the ecological environment. Drip irrigation technology is applicable to a variety of crops, especially suitable for the cultivation of drought-prone areas and high-value cash crops.

[0003] The utility model patent publication number CN221284060U in China discloses a special pipe for agricultural water-saving drip irrigation, which includes a pipe body and a branch pipe fixed on the side wall of the pipe body.

[0025] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation on the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] As shown in the accompanying drawings, a water - saving drip irrigation head includes a branch pipe 1 that is connected to a water supply pipe during use; it also includes a sleeve 2 thread - connected to the outer wall of the water outlet end of the branch pipe 1, an adjusting pipe 3 thread - connected to the inner wall of the other end of the sleeve 2, and a filter screen 4 located at the connection between the sleeve 2 and the branch pipe 1; an annular protrusion 5 for supporting the filter screen 4 is arranged inside the sleeve 2, and an inverted frustum - shaped water guide cover 6 is arranged inside the sleeve 2 and below the annular protrusion 5; both ends of the water guide cover 6 are open; a frustum cone 7 extending into the lower end of the water guide cover 6 is arranged at the upper end of the adjusting pipe 3, and the frustum cone 7 is fixedly connected to the adjusting pipe 3 through a plurality of ribs 8; a water collecting cover 9 with an open upper end is arranged inside the adjusting pipe 3, the outer edge of the upper end of the water collecting cover 9 is fixedly connected to the inner wall of the adjusting pipe 3, and a dripping port 10 is arranged at the center of the lower end of the water collecting cover 9.

[0027] As a preferred technical solution of this embodiment, the filter screen 4 is a spherical metal filter screen, and the spherical surface of the filter screen 4 faces upward.
