Referring to fig. 1 and 2, an irrigation device 10 in one embodiment includes a vehicle body 100 and a water spray assembly 200, wherein the vehicle body 100 includes a vehicle body 110 and a push-pull member 120, and the push-pull member 120 is movably connected to the vehicle body 110; the water spray assembly 200 comprises a rotatable pipe 210 and a spray head 220, wherein one end of the rotatable pipe 210 is used for communicating with a water source and is rotatably connected to the vehicle body 110, and the other end of the rotatable pipe 210 is communicated with the spray head 220 and is arranged at an included angle with the spray head 220; the push-pull member 120 drives the rotatable pipe 210 to rotate along the circumferential direction of the rotatable pipe 210 by moving relative to the body 110, so as to drive the spray head 220 to rotate along the circumferential direction of the rotatable pipe 210, thereby changing the height of the spray head 220.

When the irrigation device 10 is used, water from a water source flows out of the spray head 220 after being conveyed by the rotatable pipe 210 to irrigate gardens, when the height of the spray head 220 needs to be adjusted to wash and clean plant leaves at different heights, an external force is applied to the push-pull piece 120 to move the push-pull piece 120 relative to the vehicle body 110, so that the rotatable pipe 210 is driven to rotate along the circumferential direction of the rotatable pipe 210, and the rotatable pipe 210 drives the spray head 220 to rotate along the circumferential direction of the rotatable pipe 210. Because the spray head 220 and the rotatable pipe fitting 210 are arranged at an included angle, a certain distance exists between the water outlet end of the spray head 220 and the rotatable pipe fitting 210, when the rotatable pipe fitting 210 rotates, the water outlet end of the spray head 220 takes the rotatable pipe fitting 210 as a central shaft to do circular motion, so that the height of the spray head 220 is changed, plant leaf surfaces at different heights can be washed and cleaned, the problem that the spray head 220 of the traditional irrigation device 10 can only rotate on a horizontal plane and can not clean plant leaf surfaces at other heights is solved, the purification effect of irrigation is improved, and the cleanness of green plants is ensured.
