Abstract:
A cigarette lighter, comprising;a supporting frame disposed on a gas reservoir having a valve which is actuated by a gas lever pivotally mounted on said supporting frame for actuating said valve to release gas within said gas reservoir therefrom, wherein said supporting frame comprises two supporting walls parallelly protruded on opposite sides of said gas lever; andan ignition means comprising:a flint supported by a resilient element;a striker wheel, which is rotatably mounted between said two supporting walls of said supporting frame, comprising a central striker wheel and two side striker wheels which are coaxially connected to two sides of said central striker wheel respectively, wherein each of said two side striker wheels has a diameter equal to a diameter of said central striker wheel, and that said central striker wheel has a plurality of striking teeth provided on an outer circumferential surface thereof, and said flint is supported by said resilient element to upwardly urging against a portion of said striking teeth at position on said outer circumferential surface of said striker wheel at a location adjacent an end of said flint; anda pair of side driving wheels each having a central supporting hole, wherein said two side driving wheels are two symmetrical cap bodies each having a U-shaped cross section, and that a circular striking socket is formed at an inner side of each of said side driving wheels, in which each of said driving sockets has an inner circumferential driving surface, said two side driving wheels being rotatably covered on said two side striker wheels and said two side striker wheels are respectively inserted into said two driving sockets of said two side driving wheels while said flint upwardly extending between said two side driving wheels and urging against said central striker wheel, and that said two side driving wheels are dimensioned such that said two side driving wheels are normally disengaged with said two side striker wheels respectively for preventing a minor from driving said striker wheel to rotate, wherein said central striker wheel and said two side striker wheels each has an axial shaft hole to form an axial through hole for integrally connected with said wheel shaft, wherein each of said side striker wheels has a plurality of striking teeth provided on an outer circumferential surface thereof and said inner circumferential driving surface has a plurality of driving teeth evenly distributed thereon, wherein each of said two side striker wheels has a larger even number of said striking teeth than an odd number of said driving teeth of each of said side driving wheels,thereby, in order to ignite said cigarette lighter, an adult must apply a digital force on said side driving wheels in order to rotate said two side driving wheels to drive said striker wheel to rotate and strike against said flint to generate sparks.
