Abstract:
A piezoelectric lighter, comprising:a lighter case receiving a fuel storage and having an ignition cavity provided therein; an ignition system, which comprises: a gas emitting nozzle communicated with said fuel storage for controlling a flow of gaseous fuel; and a piezoelectric unit disposed in said ignition cavity, wherein said piezoelectric unit comprises a main piezoelectric body, a movable operating part slidably extended therefrom, and a spark generating tip extended to a position close to said gas emitting nozzle, wherein when said movable operating part is depressed with respect to said main piezoelectric body, said spark generating tip generates sparks to ignite said gaseous fuel emitted from said gas emitting fuel; and a side actuation arrangement, which comprises: a depressing button which is movably disposed in said ignition cavity and arranged to depress said movable operating part of said piezoelectric unit; and a side actuation member provided and being actuated on a side of said lighter case to drive said depressing member to depress said movable operating part of said piezoelectric unit so as to ignite said piezoelectric lighter, wherein said side actuation member is positioned in front of a sidewall of said lighter case and slidably mounted on said lighter case so as to depress said movable operating part of said piezoelectric unit by said depressing button through a guiding slot provided on said sidewall, wherein said side actuation member is pivotally connected to said lighter case so as to enable said side actuation member to rotatably slide about a pivot axle to drive said depressing button to depress said movable operating part of said piezoelectric unit to ignite said piezoelectric lighter.
