Abstract

The invention discloses an electrical inductance type flame ignitor with the flameout self-locking function. The electrical inductance type flame ignitor comprises a flame ignition coil and a flame ignition control circuit, wherein the flame ignition coil is composed of a primary coil and a secondary coil; the flame ignition control circuit is connected with the primary coil and is used for controlling a high-voltage pulse generated by the flame ignition coil; the electrical inductance type flame ignitor further comprises a flameout self-locking circuit connected with the flame ignition control circuit; and the flameout self-locking circuit is used for enabling the flame ignition control circuit to malfunction. According to the electrical inductance type flame ignitor, through additionally arranging the flameout self-locking circuit, the problems that a gasoline engine is started by mistake and is switched off not thoroughly can be avoided; in addition, the electrical inductance type flame ignitor can be connected into an engine oil sensor to realize flameout protection when the engine oil gives an alarm; and moreover, the electrical inductance type flame ignitor can prevent an external power supply from being connected into the ignitor to avoid malfunction of the ignitor.

Description

technical field [0001] The invention relates to the technical field of gasoline engines, in particular to an igniter for gasoline engines. Background technique [0002] Most of the traditional general-purpose gasoline engine igniters use figure 1 As shown in the circuit structure, the working principle of the ignition control circuit is as follows: [0003] First, the primary coil L1 of the ignition coil B1 (that is, the magneto stator) induces a set of electromotive force pulse waveforms (see waveform figure 2 ); when the leading edge of the negative pulse of the induced electromotive force of L1 arrives, the triode Q2 cannot be turned on before the triode Q3 due to the voltage division effect of the resistor R1 and the resistor R2. After the triode Q3 is turned on, the triode Q4 and the triode Q5 are turned on. After the triode Q5 is turned on, the induced electromotive force induced by the primary coil L1 of the ignition coil B1 forms a loop conduction through the prim...
