What is the principle of an arc lighter?

The arc lighter is a kind of gadget that is more common in daily life. The following is an introduction to the principle of the arc lighter. Let's take a look.






Connect a piece of piezoelectric material (crystal structure) to one end of a thin wire. This wire forms a gap with the metal material at the air outlet of the lighter. The impact of the impact block is synchronized with the opening of the air source through a mechanical mechanism. When the impact block hits the other end of the piezoelectric material block with a certain impact energy or force, the internal molecules of the piezoelectric material will vibrate strongly and transfer the vibration energy to the wire. Since the ratio of the cross-sectional area of ​​the wire to the cross-sectional area of ​​the piezoelectric material block is very large, the molecular vibration in the wire has a strong tendency to strengthen.

When the end molecules of the wire vibrate strongly and hit the air molecules at the gap, the air molecules also vibrate strongly. The trajectory of the vibration of air molecules is the electric fire (arc light) we see. These electric sparks (arc lights) are actually the trajectory of the air molecule vibration when the wire molecules vibrate strongly and transfer energy to the metal material at the air outlet of the lighter, indicating that the air molecule at the gap vibrates very strongly. According to the theory of vibration, strong vibration means that the temperature of the material is very high. When the temperature exceeds the ignition point of the liquefied gas in the lighter, the gas that escapes will be ignited to form a flame. The flame is the image of the gaseous material molecules that vibrate violently. This is the basic working principle of the lighter, and the principle of other electronic lighting devices is the same.
