There are also some matters that should be noted when using a smoker to bake the igniter

Release time:


If only one burner of the gas stove is used, then only one gas switch is turned on after pressing the ignition switch, and the ignition can work normally . There are still some things to pay attention to when using the igniter, the details are as follows:

1. Because the rechargeable battery of the switching power supply of the hood baking igniter is installed in the inner structure of the shell, it is best to install the rechargeable battery before installing it on the stove, and replace the battery Just open the cover.

2. Because the output voltage of the igniter is relatively high, when the button is pressed, the hand should not touch the position of the discharge needle to prevent the electric shock from touching the body. If it is accidentally touched, it will not be life-threatening.

3. The relative distance between the discharge ignition needle and the flame hole of the burner should be appropriate and ensure that it is firm. If it is loose, it should be corrected in time to ensure its ignition pass rate.

4. The discharge ignition needle is generally not easy to break. If it does not discharge, it may be that the battery is dead, or the fault of the single-pulse hood baking igniter is not necessarily a problem with the ignition needle. If it is replaced with a new battery, it still does not Ignite, it is recommended to find the manufacturer's after-sales service for on-site inspection.

This is an electronic small device used by a functional gas stove without ignition, and it can also be used as an emergency when the ignition function of a functional gas stove with an ignition is abnormal. The circuits of such portable natural gas hood baking igniters are very simple, and most of the circuits are display circuits.

1 principle

The circuit uses each AA battery (1.5V) power supply system. In use, when the key switch AN is pressed, the 1.5V AC voltage will firstly give T1 a bias current through the control loop formed by the eb pole of the triode T1 and Rl, B1 (the intermediate winding of the high-frequency small transformer), and T1 will be powered on and off. The flow flows through the B1 winding, and the magnetic induction single pulse generated is fed back and adjusted in the T1 bias current control loop; thus T1 enters the state of a continuous resonant circuit. On the other magnetic induction winding of B1, because the number of turns of the coil is large, a variable voltage pulse voltage is generated. The working voltage is rectified by diode D1, which can form a relatively high single-pulse AC voltage. This working voltage is charged to the C1 battery by the primary and intermediate stages of the B2 transformer; when the charged working voltage rises to the value of the reverse regulator tube of the D3 tube, the D3 will be turned on and off immediately; therefore, the control pole of the T2 thyristor gets the opening voltage, so that T2 is switched on and off, and the working voltage charged by C1 is discharged through the primary and secondary control circuits of T2 and B2 immediately, and a pulse voltage of several thousand volts is magnetically induced in the transformer winding of the secondary coil of B2; the working voltage is then induced through the transmission line To the front end of the igniter, discharge through the air gap to form a drawn arc, and use this spark discharge to ignite the stove.

In addition, on the circuit, D2 is composed of a protection circuit, which is used to discharge the reverse direction magnetic induction high-voltage pulse generated by the work of the discharge circuit. It can prevent it from harming T1, T2 and other components, and fully guarantee the safety of circuit work.
