Abstract
A windproof lighter includes a gas directing arrangement including a torch nozzle, a gas nozzle, and a gas directing unit including a torch directing conduit and a gas directing conduit for directing a flow of gas toward the torch nozzle and the gas nozzle respectively. A gas detouring unit is movably mounted to the casing to block up the flow of gas passing through the gas directing conduit while the torch directing conduit is remained open. An ignition system installed into the casing for producing sparks directed toward the gas nozzle to ignite the gas emitted from the gas nozzle to provide a visible flame, so as to ignite the gas emitted from the torch nozzle to provide a torch flame. Therefore, the lighter is capable of providing the torch and visible flames at the same time and providing only the torch flame while operating the gas detouring unit.
