The basic working principle of electronic lighters

Basic working principle of electronic lighters

The basic working principle of electronic lighters is: connect one end of a piece of piezoelectric material (crystal structure) to a thin wire, the wire A gap is formed with the metal material at the gas outlet of the lighter, and the impact of the impact block is synchronized with the opening of the gas 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 the vibration energy will be transmitted 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 vibration of the molecules in the wire has a great tendency to strengthen. When the strong vibration of the terminal molecules of the wire hits the air molecules at the gap, the air molecules also generate strong vibrations. The trajectory of the vibration of air molecules is what we see as electric sparks (arc light). These electric sparks (arc lights) are actually the trajectories of the air molecules vibrating when the wire molecules vibrate strongly and transmit energy to the metal material at the outlet of the lighter, indicating that the air molecules at the gap vibrate 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 running out will be ignited to form a flame, and the flame is the image of the violently vibrating gas molecules. This is the basic working principle of a lighter, and the same is true for other electronic lighters.

Using the piezoelectric effect of ceramics, pressing on both sides of the special ceramic sheet will generate a directional flow of electricity, thereby generating current. If you disassemble the small component, you will find the bottom ceramic sheet and the The mechanism used to strike it, this ceramic is piezoelectric ceramics. Correspondingly, if a current is applied to it, it will vibrate. The most common one is a ceramic buzzer, which is a metal disc with white ceramic on it. If the sound frequency is very high after the power is turned on, within the ultrasonic range, it is the component that emits ultrasonic waves in the B-ultrasound probe
