Abstract
A piezoelectric lighter incorporates with a safety arrangement which includes an ignition cap slidably mounted on the ceiling of the casing in a radially movable manner, wherein the ignition cap is attached to a top end of the piezoelectric unit. A locker cavity is provided at a side portion of the ignition cap wherein an elongated guiding slot is provided on the ignition cap to communicate the locker cavity with outside. A locking member includes a locking latch slidably fitted in the locker cavity in a vertically movable manner and a operation button extended from the locking latch to outside through the guiding slot, and a resilient element disposed in the locker cavity and provided between the locking member and a ceiling of the locker cavity for urging and retaining the locking member in a lower position that a bottom end of the locking latch is extended into the casing for blocking up the ignition cap from being slid sidewardly from the casing so as to lock up the ignition cap from ignition. In order to ignite the lighter, a user's thumb must push the operation button upwardly for lifting up the locking latch out of the casing. Then, push the ignition cap sidewardly to depres…
