The working principle of the circuit is as follows:
as shown in fig. 6, when the stove ignition switch, that is, the normally-open type ignition microswitch is pressed, since one end of the ignition microswitch is grounded, the gate G of the field effect transistor MOS91 in the power control module 5 is grounded through the resistor R95 and the diode D91, so that the source S and the drain D of the field effect transistor MOS91 are turned on, and the battery starts to supply power, at this time, the battery voltage is supplied to the main control chip U1 and the rear-end circuit in the main control module 1 after being subjected to voltage stabilization filtering through the capacitor C91, the electrolytic capacitor EC92, the zener diode D94, the inductor L91, the voltage stabilization chip U091, the electrolytic capacitor EC93 and the capacitor C93.
As shown in fig. 2, after the main control chip U1 in the main control module 1 is initialized after power-on, it immediately provides a voltage maintaining signal DYXH with high level valid, so that the collector C and the emitter E of the transistor Q91 in the power control module 5 are turned on, the gate G of the fet MOS91 is grounded through the resistor R93 and the transistor Q91, and the source S and the drain D of the fet MOS91 are kept turned on. At the moment, even if the ignition microswitch is loosened to an open circuit state, the battery still supplies power to the main control chip and the rear end circuit, and the circuit is kept to work normally. The ignition of the cooker is not finished, and a voltage maintaining signal is continuously given all the time.
As shown in fig. 2, after the main control chip U1 in the main control module 1 sends a voltage maintaining signal, the micro switch detection port IC-9 pin of the main control chip U1 starts to detect the state of the port, and the port is at a low level, that is, the micro switch detection module 4 detects that the micro switch is pressed and turned on; and if the port is at a high level, the micro switch is judged to be released and disconnected. When the microswitch is determined to be pressed and conducted, the ignition signal DHKZ is effective at a low level, the zero-second valve suction signal ON-L is effective at a low level, and the valve suction negative voltage signal FDYPWM square wave is immediately given.
As shown in fig. 4, the main control chip U1 in the main control module 1 outputs a low-level ignition signal DHKZ, so that the collector C and the emitter E of the transistor Q81 of the ignition module 2 are turned on, the VCC power supply forms a loop to ground through the resistor R82, the transformer TR81 and the capacitor C81, so that the collector C and the emitter E of the transistor Q83 are turned on and off continuously, an oscillating current is generated in the windings of the transformers 1 to 4, a voltage is induced in the windings of the secondary coils 5 to 7 of the transformer TR81, and the induced voltage is boosted again through the high-voltage packet GYB1 to generate an ignition spark.
As shown in fig. 5, the main control chip U1 in the main control module 1 outputs a low-level zero-second suction valve signal ON-L, so that the zero-second suction valve circuit transistor Q32 in the zero-second suction valve module 3 is turned ON, the transistor Q31 is also turned ON after the transistor Q32 is turned ON, and the ground GND and the negative voltage-3.3V form a loop through the coil of the thermocouple solenoid valve, the current-limiting resistor R33 and the transistor Q31 to maintain the solenoid valve suction.
As shown in fig. 5, the principle of generation of negative voltage in the zero-second suction valve module 3: when the negative voltage signal is at a low level and the triode Q61 is switched on, a loop is formed for the ground through Q61 and the inductor L61 at +3.3V, and current is generated in the inductor; when the negative voltage signal is at a high level, the transistor Q61 is turned off, and because the current in the inductor L61 cannot suddenly change, the current in the inductor L61 still has the same direction as the current in the transistor Q61 when the transistor Q61 is turned on, and the current forms a loop through the electrolytic capacitor EC61 and the diode D61 to charge the electrolytic capacitor EC 61. The anode of the electrolytic capacitor EC61 is connected with the current outflow end of the inductor L61, namely GND, the cathode of the electrolytic capacitor is connected with the other end of the inductor L61 through a diode D61, after the electrolytic capacitor EC61 is charged, the voltage of the cathode is lower than that of the anode, and the anode of the electrolytic capacitor EC61 is connected with GND, so that a negative voltage lower than the GND potential is generated at the cathode of the electrolytic capacitor EC 61.
After an ignition switch of the cooker is pressed, after ignition discharge, a zero-second suction valve and a negative voltage signal are given, a detection port of the microswitch continuously detects the state of the port, and whether the ignition microswitch is pressed consistently is judged to be in a conducting state. If the microswitch is detected to be always conducted, ignition discharge, zero-second suction valve and negative voltage signals are continuously given. If it is detected that the companion microswitch has released the open circuit, a timer T1 is started, which keeps giving a sustained ignition discharge, zero second suction valve and a negative voltage signal. When the timing T1 reaches 1 second, the supply of the ignition discharge signal is stopped, and the supply of the zero-second suction valve and the negative voltage signal is maintained, while the timing T2 is timed again. When the timing T2 reaches 1 second, the zero second suction valve and the negative voltage signal are stopped to be given, at the moment, the thermocouple is heated to generate thermoelectric force to maintain the suction of the electromagnetic valve, and the ignition is finished.
When the cooker is detected to enter a shutdown state after the cooker is finished, the main control chip U1 in the main control module 1 stops giving a voltage maintaining signal, the source S and the drain D of the field effect transistor MOS91 are cut off, the battery does not supply power to the circuit, and the chip and the whole circuit stop working. And waiting for the ignition microswitch to be pressed and conducted next time, and restarting the circuit.
