The invention discloses an intelligent monitoring system for a water purifier. The intelligent monitoring system comprises a power supply, a water quality detecting sensor, a water leakage sensor, anelectric leakage sensor, a filter element identity recognition device, a filter element mounting detecting device, a control valve, a wifi / NB interface and a controller; a first signal input end, a second signal input end, a third signal input end, a fourth signal input end and a fifth signal input end of the controller are connected with signal output ends of the water quality sensor, the water leakage sensor, the electric leakage sensor, the filter element identity recognition device and the filter element mounting detecting device correspondingly; and a first signal output end, a second signal output end, a third signal output end and a fourth signal output end of the controller are connected with signal input ends of the wifi / NB interface, the power supply, the filter element identityrecognition device and the control valve correspondingly. The intelligent monitoring system recognizes a filter element of a water purification processor, using standardization of the filter element is ensured, the water purifying amount of the filter element is monitored and controlled in real time, and absolute safety of the water quality is ensured; and meanwhile, electric leakage and water leakage of the water purification processor can further be monitored, and using safety of the water purification processor is ensured.
