Working principle of lighter equipment

The main components of lighters are firing mechanism and gas storage box. When the firing mechanism moves, sparks are fired into the gas zone to ignite the gas. The ignition mechanism is the most active part in the evolution of lighters, and it is also a complicated part of the structure. According to the characteristics of the ignition mechanism, lighters can be divided into six categories: flint wheel lighter, piezoelectric ceramic lighter, magnetic induction lighter, battery lighter, solar lighter and micro-computer lighter. The igniting process of their fuel is approximately the same, and the main difference lies in how the firing mechanism gets angry.

Lighter fuels are mainly flammable gases. Early multipurpose gasoline is seldom used because of its peculiar smell. Butane, propane and liquefied petroleum gas are widely used. They are pressurized and filled into closed air chambers. Once released into the air, they are endothermic and gasified, and expand rapidly, and ignite easily. Butane (CH3-CH2-CH2-CH3) used in lighters is n-butane. It is a general term for two alkane hydrocarbons with the same molecular formula (C4H10). These include: n-butane and isobutane (2-methylpropane). Butane is a flammable, colorless, liquefiable gas. It is an important raw material for the development of petrochemical industry and organic materials.
