Abstract

An irrigation device, including: a rain barrel; a water pump; a humidity detector; a permeable pipe; a control unit; a first valve; a second valve; a cleaning unit. The permeable pipe includes a plurality of circumferentially-distributed bores. The rain barrel, the water pump, the first valve and the permeable pipe are connected sequentially. The humidity detector is adapted to detect a humidity of a green land. The humidity detector and the permeable pipe are disposed in the green land. The rain barrel is connected to a municipal sewage pipe via the second valve. The cleaning unit is disposed in the rain barrel for cleaning the inner wall of the rain barrel. The first valve, the second valve, the humidity detector, and the cleaning unit are all electrically connected to the control unit.
