[0002] As an igniter, the lighter is easily blown out by strong wind in daily use, so the manufacturer extends the design of the lighter with windproof performance. The windproof combustion head is fixedly connected with the air outlet needle (not movable), and after the air outlet needle supplies air, the gas becomes high-pressure gas after being adjusted by the micro-holes (pore diameter of about 0.07mm) of the micro-hole pressurizing sheet, fully mixes with air, and is ignited by the piezoelectric igniter after the fire gathering sleeve, so as to form a flame. However, the windproof lighter still has the following shortcomings: after the ignition button is reset and the air outlet needle stops supplying air, there is still a lot of residual gas in the entire air supply channel, and the residual gas enters to make the combustion continue; as a daily necessity of people, the lighter has a relatively short continuous combustion time after stopping work at normal temperature, and basically does not affect the use experience. However, at low temperature, the continuous combustion time after stopping work is relatively long, which affects the use experience and has low safety performance.
