The invention discloses automatic water temperature adjusting equipment. The automatic water temperature adjusting equipment comprises a hot water pipe, a cold water pipe, a mixed water outlet pipe, two sets of drive components, a temperature sensor and a control unit. The hot water pipe comprises a hot water inlet. A first ball valve is arranged in the hot water pipe. The first ball valve comprises a first channel communicating with the hot water pipe. The cold water pipe comprises a cold water inlet. A second ball valve is arranged in the cold water pipe. The second ball valve comprises a second channel communicating with the cold water pipe. The mixed water outlet pipe communicates with the cold water pipe and the hot water pipe. The two sets of drive components correspondingly drive the first ball valve and the second ball valve to rotate for adjusting the water flow in the hot water pipe and the water flow in the cold water pipe. The temperature sensor at least can detect the water temperature in the mixed water outlet pipe. The control unit receives the detection temperature of the temperature sensor and controls the two sets of drive components to drive the first ball valve and the second ball valve to rotate so that the water temperature in the mixed water outlet pipe can reach the preset temperature.
