Pipeline water dispenser

The invention provides a pipeline water drinking device. The pipeline water drinking device comprises a water tank, a water inlet assembly, an electromagnetic valve, a balance water pipe, a water receiving box and a water leakage detection assembly. The water inlet assembly is connected with the water tank and used for supplementing water to the water tank. The electromagnetic valve is arranged on the water inlet assembly; the balance water pipe extends along the height direction of the pipeline drinking water device, the bottom of the balance water pipe is connected with the lower part of the water tank through a connecting pipe, and the upper part of the balance water pipe is provided with a water outlet; the water receiving box is used for receiving water flowing out of the water outlet; the water leakage detection assembly is used for detecting whether water exists in the water box or not, and the water leakage detection assembly is electrically connected with the electromagnetic valve. When the water in the balance water pipe rises to the position of the water outlet, the water in the balance water pipe flows out through the water outlet and enters the water receiving box. At the moment, the water leakage detection assembly can detect that water exists in the water receiving box and control the electromagnetic valve to be closed. In this way, the problem of water leakage caused by the fact that water replenishing is not stopped in time after water replenishing is in place can be avoided, and the risk is reduced.
