1. Windproof lighter: Using the Bernoulli principle, the windproof lighter uses a higher gas discharge speed, which can form a lower pressure on the appropriate part of the lighter's airflow passage to "suck" more air into it. It is fully mixed with the gas of the lighter, reacts violently and burns, and the high temperature formed by the flame makes the gas expand more, and the pressure increases, so that the flame is ejected at a higher speed. So it is not easy to extinguish. If the fire is extinguished, the high temperature metal mesh will ignite the fire again. The simple description is: 1. Increase the jet of air to provide sufficient flammable gas; 2. Increase the heat accumulation and provide the ambient temperature for continuous combustion of the gas, which is done through the filament (at the spout).
2. Ordinary lighters: The main components of the lighter are the ignition mechanism and the air storage box. When the ignition mechanism is actuated, a spark is emitted to the gas zone to ignite the gas. The ignition mechanism is the most active part of the evolution of the lighter, and it is also a more complex part. According to the characteristics of the ignition mechanism, the lighter can be divided into Flint steel wheel lighter, piezoelectric ceramic lighter, magnetic induction lighter, battery lighter, solar lighter, and microcomputer lighter. Their fuels are ignited in much the same way, the main difference being how the ignition mechanism is ignited. The fuel used in lighters is mainly flammable gases. Gasoline used in the early days is rarely used because of its odor. Butane, propane and petroleum liquefied gases are now used. They are pressurized and filled into a closed air box. Once released into the air, they are heated and vaporized and rapidly expand, making them easy to ignite.
