The circuit of this kind of battery operated mouse trap
is made up with trigger control circuit, audible and visual alarm circuit, wireless transmitting circuit and high pressure generator output circuit.
Trigger control circuit is made up with triggering sensor ( it is made up with two electrode that is between A and B), crystal valve V1-V4, electrical resistor R1, R2, capacitor C2, C3, diode VD1 and relay K.
Audible and visual alarm circuit is made up with musical integrated circuit IC, crystal valve V5, loudspeaker BL, electrical resistor R5 and luminous diode VL1, VL2.
Wireless transmitting circuit is made up with electrical resistor R3, R4, capacitor -C8, inductor L, crystal valve V6 and antenna W.
High pressure generator output circuit is made up with electrical resistor R6, capacitor C9, C10, boosting transformer T, crystal valve V7, diode VD2 and high voltage electrode.
After switching on S, trigger control circuit is entering stand by mode. When there is no mouse in the area, V1-V4 stop, K is released, audible and visual alarm circuit, wireless transmitting circuit and high pressure generator output circuit are all out of power, there is no pulse high pressure on the high voltage electrode.
When mouse gets into the controlled area and touches the sensor between A and B, V1, V2 will turn on and C3 begins charging. When voltage of C3 is up to a certain value, V3, V4 will be saturated conducted, the normally open contact of K will switch on so that audible and visual alarm circuit, wireless transmitting circuit and high pressure generator output circuit will start to work. After expanding musical electric signal from IC by V5, users can receive alerting signal in 1km through FM. At the same time, turning on VL1 and VL2, high pressure generator circuit works and has pulse high voltage on W3 of T, this pulse high voltage is added to high voltage electrode through VD2, at last mouse will be killed. Users can arrive at the scene in time to deal with mouse after receive alerting signal through FM.
