Patent ID: 6849990

Claim:
A piezoelectric lighter, comprising: a casing receiving a fuel storage cavity and having an ignition cavity provided therein; an ignition system which comprises: a gas emitting nozzle communicated with said fuel storage cavity for controlling a flow of gas; and a piezoelectric unit which is disposed in said ignition cavity, comprising a movable operating part extending upwardly, and a spark generating tip extended to a position adjacent to said gas emitting nozzle, wherein when said movable operating part is depressed to a predetermined ignition level, said spark generating tip generates sparks to ignite said gas emitted from said gas emitting nozzle; and a safety arrangement, which comprises: two axle holders provided on two opposed inner sides of said casing respectively, wherein each of said axle holders comprises a blocking member provided thereon; and an ignition cap which comprises a pivot arm extended downwardly into said ignition cavity, and two pivot axles outwardly extended from two sides of said pivot arm into said axle holders respectively so as to pivotally support said ignition cap on said casing in a radially movable manner, said blocking members being normally biased against said pivot axles respectively to block up a downward movement of said ignition cap, wherein when said ignition cap is radially slid on said casing, said pivot axles are rotatably moved to release a blocking up of said ignition cap with respect to said blocking members of said axle holders respectively, such that said ignition cap is capable of sliding downwardly to depress said movable operating part of said piezoelectric unit so as to ignite said piezoelectric lighter.
