Specifically, the control water pressure may be set to be 0.2MPa, 0.25MPa, 0.30MPa, etc., taking the control water pressure of 0.25MPa as an example, when the water pressure is lower than 0.25MPa, the sliding component 72 is at the first position, the groove region 73 is located at the intersection position of the sliding groove 9 and the vertical flow channel 61, and the irrigation device is in a drip irrigation state; when the water pressure is higher than 0.25MPa, the sliding part 72 slides to a second position, the non-groove area 74 of the sliding part 72 is positioned at the crossing position of the sliding groove 9 and the vertical flow passage 61, the vertical flow passage 61 is closed, and the irrigation device is in a sprinkling irrigation state; when the water pressure is lower than 0.25MPa again, the first elastic component 71 pushes the sliding component 72 to return to the first position, so that the drip irrigation and spray irrigation state switching is realized according to the pressure. The first elastic member 71 may be a spring.
Further, the side wall of the non-groove area 74 of the sliding part 72 is circumferentially provided with a first sealing ring 75, the first sealing ring 75 prevents water from flowing into the vertical flow channel 61 or the first elastic part 71 from the second end opening 92, the water leakage of the device and the corrosion of the first elastic part 71 are prevented, and meanwhile, sediment in the water injection is prevented from entering between the sliding part 72 and the sliding groove 9, so that the sliding smoothness of the sliding part 72 is ensured.

Further, there is a space between the telescopic tube 11 and the first flow channel 3, the space is provided with a second elastic component 13, the second elastic component 13 is a spring, one end of the second elastic component 13 is connected with the second opening 2, the other end of the second elastic component 13 is connected with the bottom end of the telescopic tube 11, and the second elastic component 13 is used for applying downward tension to the telescopic tube 11. When the sprinkling irrigation state, the water injection promotes the telescopic tube 11 to stretch out of the first runner 3, at this moment, the second elastic component 13 gives the telescopic tube 11 a downward pulling force, and the gravity of the telescopic tube 11 and the pulling force of the second elastic component 13 are balanced together with the water injection pushing force, and at the end of the water injection, the telescopic tube 11 can smoothly retract into the first runner 3 due to the pulling force of the second elastic component 13, so that the problem of untimely retraction caused by the falling of the gravity of the telescopic tube 11 is prevented.
