When no liquid exists in the infusion tube, equivalent to that the equivalent capacitance value on the electrode plate is small, the first end of the first integrated circuit U1 outputs low level, the first field-effect tube Q1 is in saturated conduction, at the moment, the lower electrode plate B can not detect the liquid, the equivalent capacitance value is small, the second integrated circuit U2 outputs low level, and the second field-effect tube Q2 is cut off. The optocoupler U4 has no current passing through at the primary side and the phototriode at the secondary side is cut off. Corresponding to the switch being open.
