When the electric lighter
is working, the butane is ignited by an electric spark. Therefore, the key to incineration is how to generate electric sparks. The principle of the device that generates electric sparks in the lighter is shown in the figure, and its core component is piezoelectric ceramics. Piezoelectric ceramics is a material that can convert mechanical energy into electrical energy. When piezoelectric ceramics are subjected to external pressure, the positive and negative charge centers in the ceramic separate, causing positive and negative charges to be piled up on its two surfaces to form a potential difference. If the electric charge is accumulated enough, the generated electric potential difference will be enough to break down the air and generate electric sparks.
The lighter uses this electric spark to burn. In the incineration equipment of the lighter, the potential energy is stored in the tension spring after pressing the top button, and then the stored potential energy is suddenly released to hit the piezoelectric ceramic to complete the accumulation of charges on both sides of the ceramic and discharge in an instant. Complete incineration.
