Abstract:
A childproof barbecue lighter, comprising:a casing having a liquefied gas cavity a nd a pusher cavity provided therein;a liquefied gas container being received in said liquefied gas cavity to provide liquefied gas through a gas emitting nozzle mounted on top of said liquefied gas container;an elongated nozzle tube extended from said casing and contains a gas tube therein, wherein said gas tube is extended from said gas emitting nozzle to a distil end of said elongated nozzle tube to form an ignition tip;a piezoelectric unit, which is disposed in said pusher cavity of said casing for generating piezoelectricity, comprising a movable operating part extended therefrom and a spark generating tip which is extended to said distil end of said elongated nozzle tube to produce sparks towards said ignition tip to ignite said gas emitted from said ignition tip;a pusher button which is disposed in said pusher cavity of said casing in a vertically movable manner and attached on said movable operating part of said piezoelectric unit so as to operatively connect to said piezoelectric unit, wherein said pusher button is also operatively connected to said gas emitting nozzle via a gas lever; anda locker device being installed inside said pusher cavity of said casing for blocking up said pusher button in a downward movable manner so as to lock up said pusher button for ignition, wherein said locker device comprisesa lock button being movably supported on said pusher button which has a through slot provided thereon, said lock button being slidably fitted in said through slot in such a manner that said lock button is movable with respect to the pusher button, said lock button further comprising a locking arm integrally and downwardly extended into said pusher cavity through said through slot in such a manner that said lock button is arranged to drive said locking arm to move from a normally locking position to an unlocked position,a stopper which is provided in said pusher cavity and positioned right under said locking arm of said locker device while said locker device is in said locking position so that said locker device is blocked by said stopper for any downward movement so as to stop said pusher button from any downward movement by blocking up said locking arm of said locker device, anda resilient element, which is disposed in said pusher cavity, for applying an urging pressure against said locking arm, so as to normally retain said locker device at said locking position, wherein at said locking position, said locking arm is downwardly extended and stopped by said stopper for blocking up said pusher button from being pushed downwardly so as to lock up said pusher button from ignition, and that at said unlocked position, said locking arm is moved offset from said stopper such that said pusher button is capable of being pushed downwardly to ignite said childproof barbecue lighter.
