Ignition circuit diagram of household gas stove
There are many types of electronic gas igniters. This article introduces an electronic igniter with simple structure and convenient production.
The circuit of the device is shown in Figure 1, which is composed of an oscillator, a high-voltage rectifier circuit and a booster. The oscillator is composed of triode VT and L1, L2 and R of T1. When the power switch S is turned on, VT will oscillate, so a higher voltage will be induced at the L3 end of T1, and the capacitor C will be charged after half-wave rectification by the diode VD. , and at the same time, a higher electrical pulse is induced at the L5 end of T2 for ignition. When S is set to "2", the charge in C remains discharged until the gas is ignited reliably. The entire action is completed in just a few seconds.
Component selection and production
E uses a AA battery. VT adopts germanium triode 3AX81 to improve the voltage drop characteristics under low voltage. If silicon tube is used, the voltage drop is larger and the working efficiency is obviously reduced. VD adopts 2DG series high-voltage silicon pellets, and its back pressure is required to be greater than 250V, the capacity of C is in the range of 0.47-0.68uF, and the withstand voltage is greater than 160V. T1 can use the E-type 5×7 iron core of the input or output transformer in the small semiconductor radio, L1 is wound with Φ0.17mm high-strength enameled wire for 30 turns, L2 is wound with the same diameter enameled wire for 60 turns, and L3 uses Φ0.06mm high-strength enameled wire. Strength enameled wire wound 3500 turns. T2 uses a 40mm long magnetic rod as the iron core. First, use Φ0.41mm enameled wire to wrap 17 turns on the magnetic rod to make L4, then put a plastic groove frame on L4, and use Φ0.06mm high-strength enameled wire to wrap around the frame. 1500 turns. There are 10 wire slots on the skeleton, and each wire slot is wound with 150 turns, which can effectively prevent high-voltage breakdown of L5 itself.
After the circuit is made, you can connect electrodes at both ends of L5, place them at an appropriate distance, move S, and see the sparks flashing between the two electrodes.
