1. Windproof lighter
: Using Bernoulli's principle, the windproof lighter uses a higher gas ejection speed, which can form a lower pressure on the appropriate part of the air flow channel of the lighter to "suck" more air in, and It is fully mixed with the gas of the lighter, reacts violently and burns. The high temperature formed by the flame makes the gas expand and the pressure increases, so that the flame is ejected at a higher speed. So it is not easy to extinguish. If the fire goes out, the hot metal grill will instantly reignite the fire. A simple description is: 1. Increase the airflow injection to provide sufficient combustible gas; 2. Increase the heat accumulation to provide the ambient temperature for the continuous combustion of the gas, which is done through the coil of filaments (at the nozzle).
2. Ordinary lighter: The main components of the lighter are the ignition mechanism and the gas tank. When the ignition mechanism is in action, sparks shoot out to the gas area, igniting the gas. The ignition mechanism is the most active part in the evolution of the lighter, and it is also the part with a more complex structure. According to the characteristics of the 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 fuels are ignited in roughly the same way, the main difference being how the ignition mechanism fires. The fuel used in lighters is mainly flammable gas. In the early days, gasoline was mostly used, but it is now rarely used because of its peculiar smell. Now more butane, propane and liquefied petroleum gas are used. They are pressurized and filled into a closed air box. Once they are released into the air, they will absorb heat and vaporize and expand rapidly, making them easy to ignite. The butane (CH3-CH2-CH2-CH3) used in the lighter is n-butane, which is a general term for two alkane hydrocarbons with the same molecular formula (C4H10). Includes: n-butane and isobutane (2-methylpropane). Butane is a flammable, colorless, easily liquefied gas. It is an important raw material for the development of petrochemical and organic raw materials, and its use has been paid more and more attention.
