Safety lighter

Abstract

A safety lighter includes a gas tank, a wheel racket, a file wheel assembly, and a metal cap. A wheel racket being provided at the top of the gas tank further includes two file-wheel seats having a slot extended up therefrom and a multiplicity of match-up seats. The file wheel assembly made by pressing together a file wheel with relatively smaller shaft diameter and two side wheels having external teeth at the circumference edge and with shaft diameter greater that that of the file wheel has its salient shaft pivotally connected to the slot. The metal cap being slipped on the external portion of the wheel racket has an extension portion provided at a location adjacent to the file wheel assembly. Under normal condition, the extension portion of the metal cap meshes with the side wheels of the file wheel assembly and the external teeth of the file wheel having relatively small shaft diameter such that it is not easy to ignite the lighter by turning the file wheel assembly to rub against the flint since it is propped up by the extension portion. When it comes to ignite the lighter, one needs only to exert a small force to press down the file wheel assembly and the slot will guide the salient shaft of the file wheel assembly to slide downward. After pressing down, the file wheel assembly will separate the prop-up engaging of the extension portion of the metal cap and turn the file wheel assembly to rub against the flint to generate flame to achieve the ignition action. Therefore, the lighter is capable of avoiding the children playing with the lighter to cause hazard.

1 . A safety lighter comprising:
 a gas tank for filling liquid gas;   a wheel racket further comprising two file-wheel-seat and a securing seat, the file-wheel-seat has a slot extended up therefrom and the securing seat is for placing a spring and a flint;   a file wheel assembly made by pressing together a file wheel with relatively smaller shaft diameter and two side wheels having external teeth at the circumference edge and with shaft diameter greater that that of the file wheel; and   a metal cap characterized by that the metal cap is slipped on the external portion of the wheel racket, and the metal cap has an extension portion provided at the corresponding external teeth of the file wheel assembly.   
   
   
       2 . The safety lighter as claimed in  claim 1  characterized by that the wheel racket provides a multiplicity of match-up seats. 
   
   
       3 . The safety lighter as claimed in  claim 1  characterized by that the top surface of the match-up seats of the wheel racket appears a guided surface having arcuate shaped surface. 
   
   
       4 . The safety lighter as claimed in  claim 1  characterized by that the top surface of the match-up seats of the wheel racket appears a guided surface having slant surface. 
   
   
       5 . The safety lighter as claimed in  claim 1  characterized by that an extra salient pieces are provided corresponding to the file wheel at the extension portion of the metal cap. 
   
   
       6 . The safety lighter as claimed in  claim 1  characterized by that a multiplicity of second match-up portions are provided at the metal cap corresponding to the multiplicity of match-up seat of the wheel racket.
