Abstract:
A barbecue lighter, comprising:a casing having a liquefied gas cavity and a trigger cavity provided therein; a gas emitting nozzle extended from and communicated with said liquefied gas cavity via a gas releasable valve; an elongated nozzle tube mounting on a ceiling of said casing for encircling said gas emitting nozzle; a gas lever, which is pivotally supported in said casing, having a lifting end engaged with said gas releasable valve and a depressible end arranged in such a manner that when said depressible end of said gas lever is depressed, said lifting end of said gas lever lifts up said gas releasable valve for releasing gas from said liquefied gas cavity; a piezoelectric unit, which is disposed in said trigger cavity of said casing, having an ignition tip extended adjacent to said gas emitting nozzle; an ignition trigger, which is disposed in said trigger cavity of said casing in a vertically movable manner, being attached on a top portion of said piezoelectric unit; and a safety arrangement, which comprises an actuating member comprising a pusher arm disposed in said trigger cavity in a movable manner, and a resilient element disposed between said pusher arm and said ignition trigger for applying an urging pressure against said pusher arm so as to normally retain said pusher arm in a safety position, wherein in said safety position, said pusher arm is positioned away from said depressible end of said gas lever with a predetermined distance, and in an ignition position, said pusher arm is moved to a position that when said ignition trigger is depressed downwardly, said pusher arm is driven downwardly to depress said depressible end of said gas lever for releasing gas, so as to ignite said barbecue lighter, wherein a bottom portion of said pusher arm functions as a pusher head, wherein in said ignition position, said pusher arm is moved to a position that said bottom portion thereof is positioned above said depressible end of said gas lever to depress said depressible end of said gas lever when said ignition trigger is depressed downwardly, wherein said actuating member further comprises an operation button extended from said pusher arm to outside through an operation slot provided on said ignition trigger in such a manner that said operation button is arranged to move said pusher arm from said safety position to said ignition position; wherein said pusher arm is pivotally mounted in said trigger cavity, wherein said resilient element has two ends biasing against said pusher arm and an inner wall of said ignition trigger in such a manner that said resilient element normally urges said pusher arm to slightly rotate that said bottom portion thereof is position away from said depressible end of said gas lever.
