After the stove is produced, the program in the main control chip 1 is set, but the customer needs to change the ignition time, shorten or prolong the ignition time, and the factory can directly connect the resistor R in seriesKLAnd a resistance RKRThereby changing the ignition time and the suction valve time and further changing the working mode of the ignition unit.
The left ignition unit 21 comprises a left ignition switch KL, a left oscillation boosting unit 22 and a left suction valve 41, the 4 th pin of the main control chip 1 is sequentially connected with the left ignition switch KL and the left oscillation boosting unit 22 in series, and the 6 th pin of the main control chip 1 is connected with the left suction valve 41.

The power supply voltage stabilizing module provides a voltage stabilizing power supply for the main control chip 1, the suction valve driving control module controls the opening and the closing of the suction valve, and the digital timing module times the ignition delay time and the suction valve delay time so as to achieve the purpose of accurately controlling the delay.
After the main control chip 1 is powered on, when the ignition unit enters the first path, the 8 th pin is connected with a resistor RSETo ground, RSEIf the resistance value is less than 7.5K omega, the main control chip 1 recognizes a simultaneous ignition mode, and sets the 8 th pin as a low level, and then the stove enters a standby state; when entering the second path of ignition unit, the 8 th pin resistor RSEIs not connected withGround (suspended or R)SE>7.5K omega), the main control chip 1 recognizes as the independent ignition mode, and then the oven enters the standby state.
