The invention provides a garden water-saving irrigation device which comprises an adjusting screw rod 1, an adjusting nut 2, a connecting bolt 3, a spring 4, a shell 5, a cavity 6, a restrictor 7, an adjusting spring 8, an end face sealing ring 9, a sealing cover 10, a guide column 11, a sealing ring 12, a water inlet 13, a water outlet 14, an access hole 15, a water drainage hole 16 and a pressing cap 17. The upper end of the housing 5 and the press cap 17 enclose a water outlet 14. The lower end of the shell 5 is provided with an access hole 15, and one side of the shell 5 is provided with a water inlet 13. The sealing cover 10 positioned at the access hole 15 is in threaded connection with the lower end of the shell 5, a end face sealing ring 9 is arranged on the contact end face of the sealing cover 10 and the shell 5, a guide column 11 of a cylindrical structure penetrates through a through hole in the sealing cover 10 and extends into a drain hole 16 of the shell 5, a sealing ring 12 is arranged on the contact face of the guide column 11 and the sealing cover 10, a limiting disc is arranged at the lower end of the guide column 11, a throttle 7 of a cylindrical structure is arranged at the upper end of the guide column 11, an adjusting spring 8 is sleeved on the guide column 11 in the shell 5, the upper end of the adjusting spring 8 is in contact with the throttle 7. The outer diameter of the restrictor 7 is matched with the inner wall of the drain hole 16, and a throttling groove in a spiral path is arranged on the restrictor 7.

The pressing cap 17 is fixedly connected to the shell 5 through a plurality of connecting bolts 3, the connecting bolts 3 are respectively sleeved with a spring 4, the upper end face of the spring 4 is in contact with the pressing cap 17, and the lower end face of the spring is in contact with the shell 5. The adjusting screw rod 1 passes through a through hole on the pressing cap 17 and is in threaded connection with the top of the throttler 7. The top of the pressing cap 17 is provided with an adjusting nut 2 which is in threaded connection with the adjusting screw rod 1, and the upper end of the drain hole 16 is provided with a cavity 6.

Preferably, the through hole on the pressing cap 17 is larger than the maximum outer diameter of the adjusting screw rod 1; the guide post 11 and the throttler 7 are made of plastic materials by one-time injection molding; the throttling groove on the throttling device 7 can be any one of a semicircular groove, a triangular groove and a rectangular groove; the inner diameter of the cavity 6 is larger than that of the drain hole 16; the guide post 11 is provided with scales.

When the garden irrigation water supply device works, the water inlet 13 is connected to a garden water supply pipeline, the handle at the upper end of the adjusting screw rod 1 is rotated, so that the length of the lower end of the adjusting screw rod 1 screwed into the threaded hole at the top of the restrictor 7 is adjusted, the cylindrical restrictor 7 moves up and down along the vertical axis of the cylindrical restrictor 7, and the matching height of the restrictor 7 and the drain hole 16 is changed correspondingly when the restrictor 7 moves up and down, so that irrigation water flows into the drain hole 16 from the water inlet 13, and then the length of a spiral throttling groove flowing through the matching area of the restrictor 7 and the drain hole 16 is changed along with the change.
