What Is The Working Principle Of Electric Lighter?

1. Electronic lighters contain piezoelectric ceramics, which can generate directional flow of electrons when under pressure, thus forming an electric current.

2. When pressure is applied to both sides of the ceramic in the electronic lighter, an electric current is generated. Due to the tip discharge effect, an electric spark is formed at the lighter outlet, and this spark can ignite a flame when it comes into contact with the released butane gas.

3. Piezoelectric ceramics use their piezoelectric effect to generate an electric current when under pressure. If you disassemble the small components in the electronic lighter, you can see the bottom ceramic and the knocking mechanism. This ceramic is a piezoelectric ceramic.

4. If a current is passed through the piezoelectric ceramic, it will vibrate, which is the working principle of the ceramic buzzer. The voltage in the electronic lighter is close to 10,000 volts, but the current of a single pulse is extremely small and will not cause harm to the human body.

5. Things to note when using an electronic lighter: The lighter should not be exposed to moisture, as it cannot be used if it is damp; it should not be placed under high temperatures, as dangerous sparks may be generated after being exposed to high temperatures; if the lighter has a smell of oil, you can drip water on it to check for leaks; do not leave the lighter in the car, as the high temperature inside the car may cause an explosion.
