Introduction of windproof lighters

For lighters, oil is a combustible substance, and air is a combustible substance. To maintain its combustion, we only need to keep its temperature above the ignition point. The wind can take away the heat of the flame. The greater the wind, the faster the heat is taken away. Then we only need to design a windshield device to reduce the speed of the air flowing through the flame to a certain level, and the flame can be continued to burn.

That's how the windbreak was created. Next, let's see what effect the windbreak has on the airflow over the flame. The wind blows horizontally to the windbreak wall. Most parts of the windbreak wall are non-porous. The wind is blocked and forced to flow to the sides and above. Where there are holes, a much smaller amount of air passes through the small holes, due to the iron next to the small holes. The area blocked by the sheet is the area of ​​low pressure, where the air column passing through the small hole spreads out.

Multiple vortices are formed inside the combustion chamber. Due to the different directions of these vortices, they will weaken, disturb and cancel each other, and many turbulent flows with low flow velocity are formed in the entire combustion chamber. These turbulent flows with a low flow rate are not enough for the flame of the cotton wick to quickly take away the heat. Therefore, the flame of the cotton wick can continue to be kept above the ignition point of the Z oil, and the combustion can be maintained.
