Gas switch

Abstract

The present invention provides a gas switch, which comprising: a main body, a closer set, a knob group and a primer igniter; of which, a recessed chamber is bent onto the inner wall of the main body; a driving part, arranged at one end of the closer set correspondingly to the knob group and extended into the recessed chamber, consisting of at least two driving portions correspondingly to the hammer of the piezoelectric primer; with this design, when the driving part is driven by the knob group, the driving portions could push continuously the hammer of the primer igniter to impinge on the piezoelectric primer, such that the primer igniter could perform over two continuous ignition during a single stroke of the knob group.

1 . A gas switch, comprising: a main body, a closer set, a knob group and a primer igniter; it is characterized by that:
 a recessed chamber is set onto inner wall of the main body; and   a driving part, arranged at one end of the closer set correspondingly to the knob group and extended into the recessed chamber, consisting of at least two driving portions correspondingly to the hammer of the primer igniter;   with this design, when the driving part is driven by the knob group, the driving portions could push continuously the hammer of the primer igniter, such that the primer igniter could perform over two continuous ignition during a single stroke of the button set.   
     
     
         2 . The structure defined in  claim 1 , wherein said main body is composed of a shell-like base and a cover; the closer set is arranged on the base, the knob group arranged on the cover; the primer igniter is set at one side of the cover, and the recessed chamber is bent onto the inner wall of the base. 
     
     
         3 . The structure defined in  claim 1 , wherein said driving part is provided with a sheet; a sleeving hole is set on the sheet for sleeving at one end of the closer set; two driving portions are protruded at an interval from the edge of the sheet. 
     
     
         4 . The structure defined in  claim 2 , wherein said driving part is provided with a sheet; a sleeving hole is set on the sheet for sleeving at one end of the closer set; two driving portions are protruded at an interval from the edge of the sheet. 
     
     
         5 . The structure defined in  claim 3 , wherein the driving portion contains separately a body, on the flange of which a meshing portion and an oblique sliding portion are formed separately. 
     
     
         6 . The structure defined in  claim 3 , wherein a recessed chamber is bent onto the inner wall of the main body for the movement of the driving portions. 
     
     
         7 . The structure defined in  claim 4 , wherein said driving portion contains separately a body, on the flange of which a meshing portion and an oblique sliding portion are formed separately. 
     
     
         8 . The structure defined in  claim 4 , wherein a recessed chamber is bent onto the inner wall of the main body for the movement of the driving portions.
