Abstract
A safety device for a piezoelectric lighter, which can prevent under age children from the usage of cigarette lighter without adult supervision, includes a locking stopper fitted in a locker groove of a cap body of a pusher cap in an inwardly movable manner and a resilient unit mounted between the locking stopper and the pusher cap to normally urge and retain the locking stopper positioning between the pusher head and the locking flange of a piezoelectric unit casing of the piezoelectric lighter, so as to block any downwardly movement of the pusher cap and thus prevent the ignition operation of the piezoelectric unit. In other words, the piezoelectric lighter is locked from ignition normally. In order to ignite the piezoelectric lighter of the present invention, an adult user's thumb must intentionally push in the locking stopper until it is unblocked by the locking flange and push down the pusher cap at the same time.
