ABSTRACT:
A piezoelectric lighter incorporates with a safety device which includes a pusher cap slidably mounted on a pusher cavity of a casing in a vertically movable manner and attached to a top end of a piezoelectric unit; a locking member fitting on an upper portion of the casing, wherein the locking member having a stopper latch locking up the pusher cap for blocking the pusher cap in a vertical manner. The safety device further includes a resilient unit, which is articulated on an axle mounted on the upper portion of the casing, normally urging and retaining the locking member locking up the pusher cap so as to block any downwardly movement of the pusher cap and thus prevent the ignition operation of the piezoelectric unit. Thereby, in order to ignite the piezoelectric lighter, the locking member must be pressed transversely inward to move the latch of the locking member out of the edge of the cap body of the pusher cap. Once in this position, the pusher cap can be pressed downward to compress the piezoelectric unit to ignite the lighter.
