Abstract:
A disposable lighter, comprising:a mounting frame disposed on a lighter body for receiving a liquefied fuel therein having a gas valve which is actuated by a gas lever pivotally mounted on said mounting frame for actuating said gas valve to release said liquefied fuel within said lighter body, wherein said mounting frame comprises a first and second supporting walls parallelly extended upwardly at opposite sides of said gas lever; and an ignition device comprising: a flint supported by a resilient element; a striker wheel having a circumferential coarse striking surface positioned right above said flint being rotatably mounted between said first and second supporting walls by means of a wheel axle, and two driving wheels coaxially mounted on two sides of said striker wheel respectively, wherein each of said driving wheels has a circumferential teeth surface and a diameter larger than a diameter of said striker wheel; and a child resistant device which comprises a pair of shelter wheels each including a protection disc having a center hole and a shelter ring integrally and transversally extended from a circumferential edge of said protection disc so as to define a U-shaped cross section for each of said shelter wheels, wherein said two shelter wheels are coaxially and firmly mounted at two sides of said two driving wheels by securely passing said two wheel axles through said two center holes of said two protection discs respectively, wherein an inner diameter of said shelter ring is larger than an outer diameter of said driving wheels so as to define a safety gap between an inner circumferential surface of said shelter ring and said circumferential teeth surface of each of said driving wheels, wherein each of said two shelter rings has a width shorter than a thickness of each of said driving wheels and said two shelter rings of said two shelter wheels are substantially extended to partially cover said circumferential teeth surfaces of said two driving wheels respectively so as to define an actuating edge at an uncovered portion of said circumferential teeth surface of each of said driving wheels, wherein said two shelter wheels are positioned at two outer sides of said driving wheels respectively, wherein said shelter rings are extended towards said striker wheel to cover said circumferential teeth surfaces of said two driving wheels respectively such that said two actuating edges are formed at two inner edge portions of said circumferential teeth surfaces of said two driving wheels respectively.
