Abstract

The invention relates to the technical field of ignition control of gas cookers, in particular to a single-cell thermocouple ignition control circuit. According to the specific technical scheme, the single-cell thermocouple ignition control circuit comprises a high-frequency oscillator, an SOC microcontroller and an S1 switch and an S2 switch that are parallel, wherein one ends of the S1 switch and the S2 switch are connected with the positive electrode of VCC, the output ends of the S1 switch and the S2 switch are connected with the input end of the SOC microcontroller through resistors respectively, the output ends of the S1 switch and the S2 switch are connected with two groups of boost ignition modules through diodes respectively, and the output ends of the two diodes are connected with the negative electrode of the VCC through the other diode respectively; and the SOC microcontroller is connected with the VCC through two thermocouples, the SOC microcontroller is connected with thehigh-frequency oscillator through an R1 resistor, and the high-frequency oscillator is connected with the two groups of boost ignition modules. According to the ignition control circuit, the use of discrete components is greatly reduced, the complexity of the whole circuit is reduced, the cost is reduced, the area of the PCB board is reduced, and the ignition reliability, flexibility and integration level are improved.

Description

technical field [0001] The invention relates to the technical field of ignition control of a gas cooker, in particular to an ignition control circuit of a single-cell thermocouple cooker. Background technique [0002] At present, almost every family is equipped with gas cooker or natural gas cooker. Since gas or natural gas are flammable gases, obviously the reliability of the cooker is very important, and the reliability of the cooker is reflected in the reliability of its internal ignition control circuit. . The general stove ignition circuit is composed of discrete components such as triodes, diodes, resistors, inductors and capacitors. Its main advantages are power saving, high ignition success rate, and high reliability, but there are also obvious shortcomings. , the use of a large number of discrete components makes the overall structure of the circuit complex, high cost, not conducive to the characteristics of miniaturization and integration.
