Specification for use of cigarette machine baking igniter

If only one burner of the gas stove is used, only one gas switch can be turned on after pressing the ignition power switch, and the ignition can be operated normally. There are some matters that should be noted when applying the igniter, which are as follows:

1. Because the rechargeable battery of the switching power supply of the cigarette baking igniter is installed in the internal structure of the shell, it is better to install the rechargeable battery before installing the stove, and open the cover plate when changing the battery.

2. Because the output voltage of the igniter is relatively high, when the button is moved, the hand cannot touch the position of the discharge needle to prevent elegant electric contact with the body. If tragedy touches, there will be no life threat.

3. The relative distance between the discharge ignition needle and the fire hole of the burner should be appropriate and 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 is not discharged, it may be that the battery is dead, or the common failure of the single pulse cigarette machine baking igniter is not necessarily the problem of the ignition needle. If the new rechargeable battery still does not ignite, it is proposed to find the manufacturer's after-sales service for on-site inspection.

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

1 Principle

The circuit uses the power supply system of each No.5 battery (1.5V). In use, when the key switch AN is pressed and held, the 1.5V AC voltage is first given to T1 bias current by the control loop formed by the e-b pole of triode T1 and R1 and B1 (intermediate winding of high-frequency small transformer). T1 on-off current flows through B1 winding resistance, and the generated magnetic induction single pulse is feedback regulated in T1 bias current control loop. Thus T1 enters the 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 caused. The operating voltage is rectified by diode D1, which can form a relatively high single-pulse AC voltage. This working voltage is charged by the C1 battery of B2 transformer junior high school. When the charged working voltage rises to the value of the regulator tube in the opposite direction of D3 tube, D3 will immediately collapse on and off. Therefore, the control pole of T2 thyristor is turned on and off, and the working voltage charged by C1 is immediately discharged through T2 and B2 junior high school control circuits, and a pulse voltage of several thousand volts is magnetically induced in B2 secondary coil transformer winding resistance; the working voltage is then led to the front end of the igniter through the transmission line, which discharges according to the air gap, causing an arc, and the spark discharge is used to ignite the stove.

In addition, on the circuit, D2 is composed of a protection circuit, which is used for the reverse magnetic induction high voltage pulse generated by the operation of the discharge circuit. It can prevent damage to components such as Tl and T2, and fully ensure the safety of circuit operation.
