The utility model discloses an EMU train toilet contact free water saving device relates to a toilet water saving device, particularly relates to an EMU train toilet FET voltage induction contact free water saving device. The utility model is characterized in that two sets of field effect tube voltage induction devices are provided. FET voltage induction device is composed of field effect transistor and operational amplifier integrated circuit operational amplifier integrated circuit through the switch tube is connected with the input end of the scm. The output end of the singlechip and two groups of opposite polarity switch is connected with the input end, two groups of opposite polarity switch and the solenoid valve coil is connected with the electromagnetic valve is serially connected toilet flushing pipe ends. The two sets of field effect tube voltage sensing devices are defined as 6 litres of stool flushing and 3 litres of urine flushing for users to select. The utility model overcomes the defects of the prior art that the photoelectric flushing device of the train seat toilet of the utility model does not have the defects of distinguishing the toilet from the toilet and the toilet, and is favorable for water saving.
