Chip lighter actuation mechanism

Abstract

A lighter includes a lighter casing, a gas valve, an ignition nozzle, a piezoelectric unit, and an actuation mechanism which includes a chip actuator and an actuating arm. The lighter casing, which is shaped and sized to form a stack of chips, includes an outer chip wall, and an opposed guiding wall. The chip actuator is sized and shaped corresponding to the chip wall, and is slidably mounted on the guiding wall of the lighter casing between an idle position and an ignition position. The actuating arm is extended from the chip actuator into the lighter casing through the guiding slot, in such a manner that when the chip actuator is at the idle position, it is coaxially aligned with the guiding wall that the chip actuator is overlapped with the stack of chips, and at the ignition position, the chip actuator is slid to ignite the lighter.
