Abstract:
A disposable childproof lighter, comprising:a supporting frame disposed on a gas reservoir having a valve which is actuated by a gas level pivotally mounted on said supporting frame for actuating said valve to release gas from said gas reservoir, wherein said supporting frame comprises a pair of supporting walls parallelly protruded upwardly at opposite sides of said gas level, each of said supporting walls having a supporting hole provided therein, andan ignition means, comprising:a flint supported by a resilient element,a striker wheel, which is rotatably mounted on said supporting frame, having a plurality of striking teeth evenly provided on an outer circumferential surface thereof, wherein said flint is supported by said resilient element to upwardly urging against a portion of said striking teeth,a pair of driven gear elements for coaxially mounting said striker wheel between said two supporting walls of said supporting frame, each of said driven gear elements comprising a gear wheel having an outer circumferential surface and a support shank integrally and coaxially protruded from an inner side of said gear wheel, wherein said two support shanks, which are smaller than said two gear wheels in diameter, are coaxially mounted on two sides of said striker wheel to define two supporting gaps between said two sides of said striker wheel and said two gear wheels respectively, and said two gear wheels are respectively and rotatably mounted to said two supporting walls of said supporting frame in such a manner that said striker wheel is capable of being driven to rotate when driving said two gear wheels are driven to rotate, anda pair of driving caps, each having a circular driving cavity coaxially provided at an outer side thereof so as to define an inner side wall, each of said driving cavities having a diameter larger than that of said gear wheels of said driven gear elements, wherein a central support hole is coaxially provided at each of said inner side walls for rotatably mounting on said respective support shank of said respective driven gear element while said gear wheel of said respective driven gear element is rotatably received in said respective driving cavity, wherein said two inner side walls of said two driving caps are rotatably disposed in said two supporting gaps respectively so as to hold said two driving caps in a rotatable position between said striker wheel and said two driven gear elements respectively, wherein each of said driving cavities has an inner circumferential surface, wherein said two driving caps are arranged free to rotate normally with respect to said two driven gear elements unless a downward force is intentionally applied on said driving caps while rotating said driving caps to drive said driven gear elements and said striker wheel to rotate to strike against said flint to produce sparks.
