The invention discloses an intelligent household water tank based on a temperature detection circuit, and relates to the field of intelligent household water tanks. The intelligent household water tank comprises a water tank body, a water tank table face and a water outlet pipe, wherein the water outlet pipe is connected with a cold water pipe and a hot water pipe, a flow adjusting valve A is arranged on the cold water pipe, a flow adjusting valve B is arranged on the hot water pipe, an electromagnetic valve is arranged on the water outlet pipe, and the flow adjusting valve A, the flow adjusting valve B and the electromagnetic valve are all connected with a single chip microcomputer, a selection device is arranged on the water tank table face, and the selection device is connected with thesingle chip microcomputer. The intelligent household water tank solves the technical problem that a current household water tank adopts a mechanical switch, so that intelligent control over water outflow of a water outlet pipe cannot be achieved, whether the water outlet pipe gives water out or not can be selected through the selection device on the water tank table face, the household water tankis not liable to be damaged, is convenient to operate, and thus intelligent control over water outflow is achieved.
