The invention relates to an intelligent water saving control device. The intelligent water saving control device is characterized in that the device comprises an electromagnetic valve which is used for closing a water source; the electromagnetic valve is a normally open contact switch; the electromagnetic valve is connected with a controller; the controller comprises a metering control module; and the metering control module is connected with a flow sensor. The intelligent water saving control device has advantages of reasonable and novel structure design. Through matching with a water tap, longest time in continuous water flowing can be set, or highest flow amount in continuous water flowing can be set. After the longest time or the highest flow amount which is sued for continuous water flowing is reached, the water flow can be automatically stopped, thereby effectively realizing a water saving effect. The intelligent water saving control device realizes an effect of automatically closing the water source after water supplying again on the condition of water stoppage and no man in a home. The intelligent water saving control device effectively prevent a problem of flooding in the home and can perform an effective function of preventing property flooding in the home.
