Abstract:
A piezoelectric lighter, comprising:a casing receiving a liquefied gas storage, an ignition cavity, and a nozzle cavity provided in front of said ignition cavity; a gas emitting nozzle disposed in said nozzle cavity of said casing and communicating with said liquefied gas storage for controlling a flow of gas; a piezoelectric unit disposed in said ignition cavity of said casing for generating piezoelectricity; and a safety lock, comprising: an ignition cap, having a guiding slot, slidably mounted on said casing in a radially movable manner about an operation axle provided in said casing to define a radial traveling region within said ignition cavity, wherein said ignition cap comprises a depressing arm extended to rest on said piezoelectric unit and arranged in such a manner that when said ignition cap is depressed sidewardly and downwardly at said same time, said depressing arm is driven to downwardly compress said piezoelectric unit to ignite said piezoelectric lighter; a blocking stopper provided at a front portion of said ignition cavity within said radial traveling region; a locking member comprising a locking latch disposed in said ignition cavity and an operation button extended from said locking latch to outside through said guiding slot, wherein said locking latch is movably fitted in said ignition cavity in such a manner that said locking latch is arranged to be driven by said operation button to move from a normally locked position to an unlocked position; and means for retaining said locking member at said locking position, wherein at said locking position, said locking latch is extended within said radial traveling region at a position that said locking latch is blocked by said blocking stopper, so as to lock up said ignition cap from ignition, and at said unlocked position, said locking latch is moved away from said radial traveling region so as to release a blocking up of said ignition cap with respect to said blocking stopper, so that said ignition cap is capable of being slid sidewardly and downwardly to ignite said piezoelectric lighter.
