Claim:
A safety disposable lighter, comprising: a gas casing having a liquefied gas cavity; a supporting frame, which is sealedly mounted on said gas casing, comprising two supporting walls upwardly and parallelly extended from said supporting frame; a gas valve having a gas nozzle upwardly extended from said supporting frame and communicating with said liquefied gas cavity; a gas lever pivotally mounted between said supporting walls for actuating said gas valve to release gas from said liquefied gas cavity; a flint supported by a resilient unit on said supporting frame at a position between said two supporting walls; a striking wheel assembly comprising a striker wheel rotatably mounted between said supporting walls to frictionally contact with said flint, and two driving wheels, each having a diameter larger than a diameter of said striker wheel, coaxially mounted at two sides of said striker wheel respectively and arranged in such a manner that when said driving wheels are rotated, said striker wheel is driven to rotate and strike against said flint to produce sparks towards said gas nozzle so as to ignite said emitted gas; and a shielding frame, which is securely mounted on said supporting frame, comprising: a U-shaped wind shielding guard having a top ceiling and a top flame gate formed thereon to align with said gas nozzle, wherein said wind shielding guard has a predetermined height that when said emitted gas is ignited to produce a lighter flame, a visible portion of said lighter frame is exposed to outside through said top flame gate while a root portion of said lighter flame is positioned below said top flame gate for preventing said lighter frame from being blown out; and a pair of safety guards integrally and rearwardly extended from two sidewalls of said wind shielding guard respectively and defined an ignition cavity between said two safety guards to rotatably receive said striking wheel assembly in said ignition cavity, wherein each of said safety guards has a top edge rim horizontally extended from said top ceiling of said wind shielding guard to a position above a top circumferential edge of said respective driving wheel, such that said safety guards form as a physical barrier for preventing a thumb of a child from fully engaging with said driving wheels to drive said striker wheel to rotate.
