Abstract:
1. An igniter with a safety switch, including a casing, and said casing comprising: an ignition section, disposed at an end of said casing; a gas storage tank, disposed at another end proximate to said casing for storing a gas fuel; a gas outlet valve, disposed at an end of said gas storage tank facing said casing; an electric arc generator, disposed between said ignition section and said outlet valve; a pressing section, disposed at one side of said casing, and one side of said pressing section being exposed from said casing, and another side of said pressing section being coupled to said electric arc generator; and a safety switch coupled to said gas outlet valve and movably disposed on one side of said casing and at a position proximate to said pressing section, and a first end of said safety switch being exposed from said casing, and a second end of said safety switch selectively latching said pressing section, so that said pressing section cannot be pressed while said safety switch is in an unpressed position, and wherein pressing said safety switch opens said gas outlet valve and allows the pressing section to be pressed to trigger the electric arc generator; wherein said electric arc generator comprises: a starter end, coupled with said pressing section; a conductive wire, extended into said ignition section, and when said starter end is triggered, said electric arc generator produces a high-voltage current to be sent to said ignition section through said conductive wire and produces an electric arc inside said ignition section; and a ground end, coupled with a fixed stand inside said casing, and said fixed stand is coupled with said ignition section, such that said ground end is electrically coupled with said ignition section to form an electric arc generate circuit; wherein said ignition section comprises: a nozzle, disposed at the middle of said ignition section; and a discharge pin, disposed proximate to said nozzle and coupled with said conductive wire, and when said gas fuel flows into said ignition section and said discharge pin receives a high-voltage current, said electric arc produced on said discharge pin lights up said gas fuel flowing out from said nozzle; wherein said gas outlet valve comprises: a pipe body, having an end coupled to said gas outlet valve, and the other end being coupled to said nozzle; and a driving plate, pivotally coupled with said casing, and a first end of said driving plate being latched to said gas outlet valve, and a second end of said driving plate being coupled with said safety switch, and said safety switch being pushed to drive the second end of said driving plate, so as to open said gas outlet valve; wherein the pressing section further comprises: a first accommodating space, facing said safety switch and accommodating a portion of said safety switch, when said safety switch is in an unpressed position; and a second accommodating space, facing said electric arc generator and being capable of accommodating said starter end, and said starter end precisely presses against a bottom of said second accommodating space; wherein the first end of said safety switch has an end extended outside said casing, and the second end of said safety switch end comprises: a panel member, having a first end accommodated in said first accommodating space when said safety switch is in an unpressed position; a resilient device, disposed between a second end of said panel member and a rib disposed in said casing, such that the resilience of said resilient device pushes the second end of said panel member, and the first end of said panel member is biased towards said first accommodating space; and a driving end, coupled to said driving plate, and when said safety switch is pressed, the first end of said panel member leaves said first accommodating space while said driving end presses said driving plate.
