Shuangkai Lighter - Pursue quality and cast high-quality goods.
Let us first analyze why the lighter is blown out. We know that there are three elements in combustion, which are combustibles, combustion-supporting substances (here is oxygen), and reaching the ignition temperature. Press the button of the lighter, and the gas is ejected and mixed with oxygen, and at the same time, the piezoelectric ceramic igniter releases an electric spark, which makes the gas reach the ignition temperature and is ignited. Because the temperature generated by the combustion of gas is higher than the ignition temperature of the gas, the gas can continue to burn without re-ignition. The fact that the lighter was blown out was because the wind lowered the temperature below the ignition temperature of the gas, and one of the three elements of combustion was missing, so it could not continue to burn.
Therefore, the main function of windproof lighters is to maintain the temperature above the ignition temperature. This is mainly achieved through the special structure of windproof lighters. Let us analyze it from bottom to top.
windproof lighters parts construction
The bottom of this part is a metal mesh. It can play two roles, one is to make the gas spray out at a high speed (imagine that you block the faucet with your hand, and then you are sprayed on your face), and the other is to disperse the gas so that the gas can fully mix with the air.
metal mesh at the bottom
Above the metal mesh, there are two holes on the sides of the part, which are air intake holes. According to Bernoulli's principle, the high-speed jet of gas will "suck" the surrounding air. The air is sucked in from these two air intake holes, fully mixed with the ejected gas, and burns more completely.
The top of the part is the combustion chamber, which is different from the exposed flame of ordinary lighters, but part of the flame of windproof lighters is in the combustion chamber, which enhances the windproof ability.
the combustion chamber and sheet metal
Finally, there are several pieces of metal on top of the combustion chamber that will burn red during the combustion process. If the flame is blown out by the wind, the hot metal piece can provide a high temperature to ignite the flame again.
