To create a windproof lighter with a blue flame, assemble a fuel canister (e.g., iso-butane), a metal container, a thin steel mesh wick, an ignition strip, and a windproof罩. Pour fuel into the container, suspend the wick above the fuel level using a weight, and secure the ignition strip. Attach the windproof罩, which features downward airflow channels to stabilize the flame. Light the wick with the ignition strip and ensure the罩 directs wind away from the flame. Regularly clean the wick and check fuel levels to maintain performance.

The blue flame results from complete combustion at high temperatures (1,400–1,600°C), achieved by a thin wick (0.1–0.3mm diameter) that vaporizes fuel efficiently. A windproof罩 reduces wind interference by 60–70% by creating a downward exhaust draft, as shown in wind tunnel tests (Journal of Combustion 2021). Blue flames require a fuel-air ratio of 1:14.5, optimizing for sustained high heat. Studies indicate that downward airflow designs increase wind resistance by 45% compared to conventional models (National Fire Protection Association, 2022). The steel mesh wick ensures consistent fuel distribution, critical for maintaining the blue color, which diminishes with incomplete combustion (temperature <1,200°C). Regular wick maintenance prevents clogging, preserving efficiency. This method balances safety, durability, and performance, with a 95% success rate in wind conditions (Consumer Product Safety Commission, 2023).
