Principle and structural solution of windproof lighter

According to Bernoulli's principle, the windproof lighter can form a lower pressure at an appropriate position on the airflow channel of the lighter by using a higher gas ejection speed, so as to "inhale" more air, fully mix with the gas of the lighter, and violently react and burn. The high temperature formed by the flame makes the gas expand more, the pressure increases, and the flame ejects faster. So it is not easy to go out. If the fire goes out, the high-temperature metal mesh cover will instantly ignite the fire again.

The short description is: 1. Increase airflow injection to provide enough combustible gas; 2. Increase the heat accumulation and provide the ambient temperature for the continuous combustion of gas, which is accomplished by the filament coil (at the nozzle).
