Principle of self-excited single arc lighter

Arc lighter is a common kindling tool, its principle is to use arc discharge to ignite fuel, with instant ignition, no spark pollution and other advantages.

The structure of the arc lighter includes battery, circuit, high voltage transformer, electrode and other components. When the ignition button of the lighter is pressed, the battery provides current, which is transmitted through the circuit to the high-voltage transformer. A high-voltage transformer converts low voltage current into high voltage, up to several thousand volts, and turns the current into high-frequency alternating current. This creates a high-frequency, high-voltage electric field, which creates an arc discharge between the electrodes.

Arc discharge means that when the voltage between two electrodes exceeds a certain value, the molecules in the air will be ionized, forming electrons and ions. When ions move towards the electrode under the action of electric field and collide with air molecules, they will excite the air molecules, generate light and heat, and form an arc. The temperature of the arc discharge can reach several thousand degrees, enough to ignite the fuel.

The electrode of the arc lighter is the key component, it is where the arc is generated. Electrodes are usually made of metal materials, such as tungsten, chromium, copper, etc. Tungsten electrode is a common electrode material for electric arc lighters with high temperature resistance and long life.

The advantages of electric arc lighter are fast ignition, no flame pollution, suitable for outdoor camping, barbecue, cigarette lighting and other occasions. However, there are also disadvantages, such as the need to replace the battery regularly, electrode wear, and easy to be blown out by the wind.

Electric arc lighters also have some safety precautions. First of all, avoid pressing the ignition button for a long time to avoid overheating the battery or burning the electrode. Secondly, when using, be careful not to let the arc come into contact with the skin or other flammable materials to avoid fire. Finally, keep it out of reach of children to avoid accidents.

Arc lighter is a kind of convenient and practical kindling tool, its principle is to use high voltage electric field to generate arc discharge to ignite fuel. Although there are some disadvantages and safety hazards, it is still a commonly used kindling tool as long as it is used correctly.
