Patent ID: 6988884

Claim:
A utility lighter, comprising: a lighter housing having a fuel-storage cavity for storing a liquefied gas therein, an ignition cavity, an operation cavity and said ignition cavity, and an operation slot formed on said lighter housing to communicate said operation cavity to outside; a gas valve upwardly extended from said fuel-storage cavity for release said gas therein when said gas valve is uplifted; an ignition nozzle supported in said ignition cavity and communicated with said gas valve; a piezoelectric unit disposed in said ignition cavity for generating piezoelectricity, wherein said piezoelectric unit has a movable part and a spark generating tip extended towards said ignition nozzle in such a manner that when said piezoelectric unit is compressed, a spark is generated at said spark generating tip for igniting said emitted gas through said ignition nozzle; and a safety device, which comprises: a pusher button, having a pushing portion, slidably mounted on said lighter housing along said operation slot, wherein when a pushing force is applied on said pushing portion of said pusher button, said pusher button is vertically slid along said lighter housing to lift up said gas valve and to compress said piezoelectric unit at said same time; a restraining latch provided at said operation cavity; a safety rotor, having a blocking latch, rotatably mounted at said pusher button to move between a locked position and an unlocked position, wherein at said locked position, said blocking latch of said safety rotor is aligned with said restraining latch to lock up said pusher bottom from sliding vertically, and at said unlocked position, said safety rotor is rotated at a direction opposite to a sliding movement of said pusher button to drive said blocking latch offset from said restraining latch, such that said pusher bottom is adapted to slide on said lighter housing to ignite said utility lighter; and a resilient element supported at said pusher button to retain said safety rotor at said locked position.
