Background
The ignition control circuit of the traditional general gasoline engine igniter is shown in figure 2, and can provide enough high voltage to ignite the mixture in the engine cylinder through the spark plug when the engine needs to ignite, so that the ignition combustion of the mixture in the gasoline engine cylinder is realized. Specifically, the flameout operation principle of the circuit shown in fig. 2 is as follows: when the flywheel (namely, a magneto rotor) embedded with a permanent magnet rotates for a circle, the igniter (namely, a magneto stator) induces a group of electric pulse waveforms shown in fig. 3 in the primary coil L1, an ignition control circuit does not work when positive pulses are applied, and the ignition coil 10 is controlled to ignite for one time/one circle when negative pulses are applied to the ignition control circuit; when the engine needs to be shut down, the switch S1 is manually closed, the switch S1 and the primary coil L1 form a loop after the switch S1 is closed, the electromotive force induced by the primary coil L1 is released in a short circuit mode, and the igniter is immediately shut down.

The utility model provides an inductance type point firearm with locking function after time delay is put out before flame-out, its ignition control circuit's theory of operation is the same with traditional theory of operation, therefore no longer gives unnecessary details here, now makes as follows explanation with flame-out control circuit's theory of operation:
when the engine needs to be shut down, the switch S1 is manually closed, the primary coil L1 (point A) induces a set of electromotive force waveforms shown in the figure 3 every time the magneto rotor rotates one circle, and the shut-down control circuit does not work when a positive pulse comes. When a negative pulse arrives, a main loop is formed by the switch S1, the diode D1, the resistor R6 and the capacitor C2 to charge the capacitor C2, a loop is formed by the switch S1, the diode D1, the resistor R6, the resistor R7, the capacitor C3 and the resistor R8 to charge the capacitor C3, and the voltage on the capacitor C2 is divided by the resistor R7 to be higher than the voltage on the capacitor C3. When the pulse gap of the primary coil L1 comes, the capacitor C2 discharges, a loop formed by the capacitor C2, the resistor R7 and the capacitor C3 continuously charges the capacitor C3, the capacitor C3 maintains a stable charging process, and the voltage gradually rises. The permanent magnet flywheel (magneto rotor) supplements electric quantity to the capacitor C2 once per rotation to ensure the supply of the capacitor C3 power supply, the voltage rising process of the capacitor C3 forms the time delay before flameout, the time delay is controlled by the capacity of the capacitors C2 and C3 and the resistance value of the resistor R7, and the time for completing the combustion of the residual gasoline after the fuel supply valve is closed is taken as the standard.
When the voltage of the capacitor C3 rises to the threshold voltage of the MOS transistor Q7, the MOS transistor Q7 is conducted, a loop is formed by the capacitor C2, the resistor R9, the resistor R10 and the MOS transistor Q7, base bias voltage is provided for the triode Q6, and the triode Q6 is conducted along with the base bias voltage; then, a loop is formed by a capacitor C2, a triode Q6, a resistor R12, a thyristor Q8 and a resistor R13, gate current is provided for the thyristor Q8, and the thyristor Q8 is switched on. After the thyristor Q8 is switched on, a loop is formed by the primary coil L1, the thyristor Q8 and the resistor R13, the electromotive force induced by the primary coil L1 is released, and the igniter is immediately extinguished.
After flameout, a primary coil L1, a thyristor Q8, a diode D2 and a capacitor C2 form a loop, so that the capacitor C2 is continuously supplemented with electricity, and the MOS tube Q7, the triode Q6 and the thyristor Q8 can be kept continuously conducted. At this time, even if the switch S1 is turned off, the key-off state, i.e., the key-off locked state, can be maintained. Until the permanent magnet flywheel stops, the primary coil L1 does not generate induced electromotive force any more, so that the capacitor C2 cannot be supplemented with electric quantity, the MOS tube Q7, the triode Q6 and the silicon controlled rectifier Q8 are cut off successively, the flameout locking state is released, and the normal ignition state is recovered when the engine is restarted.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
