ABSTRACT:
A piezoelectric lighter with safety lock, which can be a cigarette lighter or a barbecue lighter, includes a spring lock unit disposed inside a pusher cavity of a pusher cap, which includes a locking heel extended upwardly, a release button sidewardly extended from the locking heel through a locking hole provided on a side wall of a piezoelectric unit casing until a pressing end thereof normally exposed outside, and a spring member integrally extended from the locking heel to another side wall of the piezoelectric unit casing so as to urge the locking heel positioning in a locking condition to block the downward movement of the pusher cap so as to prevent any lighting operation of a piezoelectric unit received in a casing of the piezoelectric lighter. Only when the release button is pressed inwards to push the locking heel inwardly to an unlocking condition, where the locking heel is aligned with the unlocking groove of the pusher cap, the pusher cap is unlocked to be capable of pushing down simultaneously to press the moveable operating part of the piezoelectric unit to ignite the lighter.
