Abstract: A piezoelectric lighter includes a lighter housing having a liquefied gas storage, a gas emitting nozzle extended from the liquefied gas storage, a piezoelectric unit disposed in the lighter housing, and a lighter cap slidably coupled on top of the lighter housing above the piezoelectric unit. The gas emitting nozzle is slidably received at a nozzle window of the lighter cap, wherein an exit opening of the gas emitting nozzle is embedded in the ceiling of the lighter cap to protect the exit opening of the gas emitting nozzle. When the lighter cap is depressed to expose the exit opening of the gas emitting nozzle above the ceiling of the lighter cap, the piezoelectric unit is depressed and the gas emission unit is actuated at the same time to produce a flame at the exit opening of the gas emitting nozzle.
