A contact free toilet flush variable single-chip microcomputer control device includes two FET sensing device, which is characterized in that the FET induction device comprises a field effect transistor and amplifier circuit, amplifier circuit is connected with the input end of the SCM, the output end of the singlechip are respectively connected with the switch tube, the switch is respectively connected with the relay coil, public contact of the relay are respectively connected with the electric control valve, DC power supply (+) (-) connected with a relay normally open normally closed contact, the electric control valve is installed at the bottom of the water tank of the toilet water outlet end. The two voltage sensing devices of the field effect tube are respectively defined as 6 liters of stool flushing and 3 liters of urine flushing for users to select. The utility model has the advantages that the utility model overcomes the defects of inconvenient use and cross infection that the toilet type toilet and the toilet flushing device are controlled by contact type key. The toilet adopts an electric control valve, which is not easy to be affected by impurities in water, and is suitable for being used in a bad water environment.
