An ignition wheel for disposable gas lighters

摘要

The utility model relates to an igniting wheel of a disposable gas lighter, in particular to the igniting wheel which is composed of a roller closely jointed by a main body and a flint stone and side wheels combined at the both sides of the roller and integrally driven by the pressure from the user and the roller. When the igniting wheel is rotated, the liquefied gas stored in a can and ejected from a nozzle can be ignited by the spark produced under the rubbing effect with the flint stone, prior side wheels made of zinc are changed to the side wheels made of plastic material coated with fire retardant, or the diameter of the side wheels is reduced, thus the thermal damage of the side wheels caused by the flame which is produced by ignition can be prevented, and simultaneously the production cost of the disposable lighter can be reduced. The igniting wheel of the disposable gas lighter is composed of the roller with a frication bulge formed on the peripheral surface so that the spark is produced by the rubbing effect with the flint stone when the roller is rotated and a pair of side wheels combined at the both sides of the roller and integrally driven with the roller, wherein, the fire retardant is coated on the surface of the side wheels which is made of plastics.
