In the novel burner, after a fire source is extinguished due to various reasons in the initial stage before ignition of the burner body and in the combustion process, a cooker is placed on the burner body 3 to shield a light source in the burner body, so that the light receiving surface of the photoresistor RL is in a high resistance state due to no proper illumination, the base voltage of a 12V power supply anode entering an NPN triode Q3 is lower than 0.7V after being subjected to voltage reduction and current limitation by the photoresistor RL (the resistance of the photoresistor RL is about 10M at the moment), the collector of the NPN triode Q3 is in a cut-off state and is not output and enters the negative power supply input end of a relay J3, and the relay J3 is in a power-off state and controls the power supply input end and the normally closed; the positive pole of the 12V power supply enters the input end of the control power supply of the relay J through the input end of the control power supply of the relay J3 and the normally closed contact end, and enters the input ends of the positive power supplies of the relays J1 and J2 through the input end of the control power supply of the relay J and the normally closed contact end. After the 3-pin output positive power supply of the voltage-stabilized power supply A1 enters the positive power supply input end of the relay J, the control power supply input end and the normally closed contact end of the relay J are closed because no input is input at the negative power supply input end of the relay J at the moment, so that the 12V power supply positive electrode can enter the positive power supply input end of the relay J1 and the normally closed contact end of the relay J2 through the control power supply input end of the relay J, and then the relay J1 and the J2 are powered on and closed, and the control power supply input end and the normally open contact end of the relay J1 and the J2 are. After the relay J2 is electrified to attract the control power supply input end and the normally open contact end of the relay J2 to be closed, because the control power supply input end of the relay J2 is connected with the anode of the diode VD, the normally closed contact end of the relay J2 is connected with the other end of the primary winding L1 of the transformer T, one end of the primary winding L1 of the transformer T is connected with one pole of the alternating current power supply through the resistor R1, the other end of the primary winding L1 of the transformer T is conducted in a single direction through the diode VD, and the resistor R3 is connected with the other pole of the alternating current power supply, at the moment, two ends of the primary winding L1 of the transformer T are respectively communicated with the anode and the cathode of the 220V alternating current power supply. The 220V alternating current power supply enters an initial stage of a primary winding L1 of a transformer T, the 220V alternating current power supply charges an electrolytic capacitor C1 after being subjected to voltage reduction and current limiting by two resistors R1 and R3 and half-wave rectification by a diode VD, when a relay J2 is electrified and closed, the power supply charged by the electrolytic capacitor C1 is subjected to instantaneous discharge through a primary winding L1 (the electrolytic capacitor C1 is subjected to discharge through the primary winding L1 of the transformer T, the discharge time is short, the current is high, so that high voltage can be induced and generated in a secondary winding L2 of the transformer T), thus tens of thousands of volts of high-voltage pulses can be induced and generated in the secondary winding L2 of the transformer T and enter two discharge needles F, and high-voltage electric sparks generated between the upper ends of the two discharge needles F can ignite combustible gas or atomized fuel.

As shown in fig. 2, when the relays J1 and J2 are powered on and attracted, the relay J2 turns on the positive electrode of the diode VD and the other end of the primary winding L1 of the transformer T, and the discharge needle F generates sparks, and the relay J1 is powered on and attracted, and the control power input end and the normally open contact end of the relay J1 are closed, the positive electrode of the 12V power supply controls the power input end and the normally closed contact end through the relay J3, the power input end and the normally open contact end of the relay J1 control power supply, the electrolytic capacitor C is charged through the adjustable resistor RP, the voltage obtained from the positive electrode of the 12V power supply by the base of the darlington tube formed by the NPN triodes Q1 and Q2 through the resistor R2 and the adjustable resistor RP is lower than 0.7V during the initial time (for example, 0.2 seconds) because the electrolytic capacitor C is not fully charged, then the base of the NPN triodes Q1 and Q2 stop, and the, then the relays J1, J2 also continue to remain in an electrically engaged state. When the charging is about 0.2 second and the electrolytic capacitor C is fully charged, the voltage obtained from the positive pole of a 12V power supply by the base electrode of a Darlington tube consisting of NPN triodes Q1 and Q2 through a resistor R2 and an adjustable resistor RP is higher than 0.7V, so that the NPN triodes Q1 and Q2 conduct the collector electrodes thereof to output low level to enter the power input end of the negative pole of the relay J, the relay J is electrified to attract the control power input end and the normally closed contact end to be open; because the positive power input ends of the relays J1 and J2 are connected with the normally closed contact end of the relay J, the relays J1 and J2 are in a power-off state at the moment, and the control power input ends and the normally open contact end of the relays J1 and J2 are in open circuit; after the relay J2 loses power and the control power supply input end and the normally open contact end are opened, then, the anode of the diode VD and the other end of the transformer T primary winding L1 are also opened, the transformer T secondary winding L2 does not generate high voltage any more and preparation is made for generating high voltage next time (in the period, the 220V power supply is reduced in voltage and limited in current through the resistors R1 and R3, the diode VD is half-wave rectified to charge the electrolytic capacitor C1, power is supplied to the transformer T primary winding L1 next time, and preparation is made for generating high voltage by the transformer T secondary winding L2). After the relays J1 and J2 lose power, the positive pole of the 12V power supply does not enter the adjustable resistor RP to charge the electrolytic capacitor C through the power supply input end and the normally closed contact end controlled by the relay J3, the power supply input end and the normally open contact end controlled by the relay J1, and after about 0.2 second, the voltage charged by the electrolytic capacitor C is not enough to maintain the NPN triodes Q1 and Q2 to be continuously conducted (in actual conditions, although the 12V power supply does not charge the electrolytic capacitor C through the adjustable resistor RP, the voltage charged by the electrolytic capacitor C can continuously keep the NPN triodes Q1 and Q2 to be conducted for a period of time, because the power supply input end of the positive pole of the relay J is connected with the pin 3 of the stabilized voltage power supply A1, the relay J can continuously keep the power on and attract one end), the NPN triodes Q1 and Q2 stop the collectors thereof and do not output low level to enter the power supply input end of the negative pole of the relay J, the relay J, thus, the relays J1 and J2 can be electrified to close the input end of the control power supply and the normally open contact end; after the relay J2 is electrified and attracted, the relay J2 is connected with the anode of the diode VD and the other end of the primary winding L1 of the transformer T again, the relay J2 is electrified again to attract the moment that the input end of the control power supply and the normally open contact end of the relay J2 are closed, the power supply charged by the electrolytic capacitor C1 is discharged instantly through the primary winding L1 again, the secondary winding L2 of the transformer T generates high voltage again, therefore, tens of thousands of volts of high-voltage pulses generated by the secondary winding of the transformer T enter two discharge needles F again, and high-voltage electric sparks generated by the discharge needles F continue to ignite combustible gas or atomized fuel again; the relay J1 is electrified to attract the control power supply input end and the normally open contact end to be closed again, the 12V power supply charges the electrolytic capacitor C through the adjustable resistor RP again, after the interval of 0.2 second and about the interval of 0.2 second, the relay J is electrified again to attract the control power supply input end and the normally closed contact end to be opened again, furthermore, the relays J1 and J2 lose power again, the anode of the diode VD and the other end of the primary winding L1 of the transformer T are opened again, the secondary winding of the transformer T does not generate high voltage any more, preparation … … is prepared for generating high voltage next time, the processes are circulated continuously, after the fire source is extinguished in the initial stage of use or during the combustion of the burner, the ignition control circuit, the delay circuit and the light control circuit control the discharge needle F to discharge for 0.2 second, and the discharge is carried out again for 0.2 second at intervals until the combustible gas and the atomized liquid fuel are ignited. In the circuit, a user or a production technician can change the charging time of the electrolytic capacitor C by adjusting different resistance values of the adjustable resistor RP, namely, the conducting time of the NPN triodes Q1 and Q2 and the power-on pull-in time of the relay J, when the resistance value of the adjustable resistor RP is adjusted to be large, the charging time of the electrolytic capacitor C is prolonged, then the conducting time of the NPN triodes Q1 and Q2 and the power-on pull-in time of the relay J are increased at intervals, and the ignition frequency of the discharge needle F is slowed down (for example, the discharge needle F works in a working mode of discharging for 0.3 second and discharging for 0.3 second at intervals); when the resistance value of the adjustable resistor RP is adjusted to be small, the charging time of the electrolytic capacitor C is shortened, the intervals of the conduction time of the NPN triodes Q1 and Q2 and the power-on attraction time of the relay J are reduced, and the ignition frequency of the discharge needle F is accelerated (for example, the discharge needle F works in a working mode of discharging for 0.1 second, and discharging for 0.1 second every 0.1 second); when the fuel is adjusted for use for the first time, corresponding combustible gas and atomized fuel can be fully ignited within a certain time, and then the actual requirements can be met.

As shown in fig. 1 and 2, after the atomized fuel oil or natural gas is ignited by the discharging needle F, the light source generated by combustion acts on the light receiving surface of the photosensitive resistor RL (at this time, the resistance of the photosensitive resistor RL is about several hundred K), the voltage of the 12V power supply positive electrode is reduced by the photosensitive resistor RL, the current is limited, and the voltage of the base electrode entering the NPN triode Q3 is higher than 0.7V, so that the NPN triode Q3 is in a conducting state, the collector electrode outputs a low level and enters the negative power supply input end of the relay J3, and the relay J3 is in a powered state, and the control power supply input end and the normally closed; the positive pole of 12V power no longer through relay J3 control power input end and normally closed contact end, relay J1 control power input end and normally open contact end get into relay J control power input end, so the positive pole of 12V power no longer gets into relay J1 through relay J control power input end and normally closed contact end, the positive power input end of J2, relay J2 is in can losing the electric state and just can not switch on diode VD positive pole and transformer T primary winding L1 one end again, transformer T secondary winding L2 also does not produce high voltage electric spark, thereby accomplish ignition work. The resistances of the resistors R2, R1 and R3 are 470K, 47K and 47K respectively; the model numbers of NPN triodes Q1, Q2 and Q3 are 9013; the diode VD is model 2CP 20; the models of the electrolytic capacitors C, C1 are respectively 4.7 mu F/25V and 47 mu F/300V; the photoresistor RL model is MD 45; relays J, J1, J2, J3 are DC12V relays; the adjustable resistor RP is 387 omega (a plurality of resistors are connected in series).
