It is a small-size automatic water spray device. The characteristic is: it comprises hose, timer, control circuit, electromagnetic valve and spray head. The hose inlet is connected to the tap water and its outlet is connected to the spray head so as to form into the water supply channel where the electromagnetic valve is installed. The output signal of the timer is connected to the input port of the control circuit and the output port of the control circuit is connected to the control end of the electromagnetic valve. This is a practicable and new type system in which the tap water is used as the source of water and the water supply channel and spray head are set up and the electromagnetic valve is installed in the water supply channel to spray water automatically on the potted flowers and grass and plants in the households, offices, public places and other indoor locations at a required time by opening the electromagnetic valve through the control circuit preset by the timer, thus to reduce the time of manually handling the potted flowers and grass and plants and increase the level of automated service for the potted flowers and grass and plants in the households, offices, public places and other indoor locations.
