Patent ID: 7247015

Claim:
A piezoelectric lighter, comprising: a lighter casing which has an outer curved surface, a button receiving slot indently formed on said outer curved surface, and a fuel storage compartment provided in said lighter casing for storing liquefied gaseous fuel; an ignition nozzle communicatively extended from said fuel storage compartment to said outer surface of said lighter casing; a gas releasing valve communicated said fuel storage compartment with said ignition nozzle for controlling said fuel to release at said ignition nozzle when said gas releasing valve is uplifted; a piezoelectric unit, which is received in said lighter casing, comprising a depressible part extended upwardly and a spark generation tip towards said ignition nozzle for generating a spark at said ignition nozzle to ignite said fuel at said ignition nozzle when said depressible part is depressed; and a push button arrangement, which comprises: a push button, having a pusher end portion, a pivot end portion pivotally mounted at said lighter casing at said button receiving slot thereof, and a curved button surface extended from said pusher end portion and said pivot end portion, wherein said curved button surface of said push button has a curvature corresponding to a curvature of said outer curved surface of said lighter casing to assimilate said outer surface to be aesthetically in harmony with said lighter casing as an integral outer surface thereof, wherein said push button is adapted to pivotally fold between an operation position and a hidden position, wherein at said operation position, said pusher end portion of said push button is upwardly folded above said outer curved surface of said lighter casing to align said pivot end portion of said push button with said depressible part of said piezoelectric unit such that said pusher end portion of said push button is adapted to be depressed to depress said depressible part of said piezoelectric unit and to lift up said gas releasing valve for ignition, and at said hidden position, said pusher end portion of said push button is pivotally folded into said button receiving slot to align said curved button surface of said push button with said outer curved surface of said lighter casing so as to completely hide said push button in said button receiving slot within said lighter casing.
