The fuel used in lighters is mainly flammable gas. Gasoline was widely used in the early days, but it is rarely used now because of its peculiar smell. Butane, propane and liquefied petroleum gas are widely used. They are pressurized and filled into a closed air box. Once released into the air, they absorb heat, vaporize and expand rapidly, which is easy to ignite.
the main components of a lighter are the ignition mechanism and the gas storage box. When the ignition mechanism operates, sparks are emitted to the gas area to ignite the gas. Ignition mechanism is the most active part in the evolution of lighters, and it is also a part with complex structure.
According to the characteristics of ignition mechanism, lighters can be divided into six categories: flint steel wheel lighters, piezoelectric ceramic lighters, magnetic induction lighters, battery lighters, solar lighters and microcomputer lighters. Their fuel ignition process is almost the same, and the main difference lies in how the ignition mechanism ignites.

Classification
1. Gas lighter: propane, whose standard pressure is 24℃, exceeding 14kpa.
2. Post-mixed lighter: This kind of gas lighter burns with air and fuel after ignition.
3. Pre-mixed lighter: The fuel gas of this kind of gas lighter is mixed with air before burning.
4. Disposable lighters: These lighters are filled with fuel and cannot be inflated repeatedly.
5. Rechargeable lighters: This kind of lighters can be refilled with external gas tanks or inserted with new fuel gas tanks.
6. Adjustable lighter: This kind of lighter provides a device that can freely adjust the flame height.
