Abstract:
A piezoelectric lighter, comprising:a casing which comprises a liquefied gas storage and a piezoelectric unit casing which is attached to said liquefied gas storage and defines a pusher cavity therein, wherein a top edge of an outer wall of said piezoelectric unit casing functions as a locking flange with a predetermined thickness;a gas ejection nozzle which appears from a ceiling of said piezoelectric unit casing and communicating with said liquefied gas storage for controlling flowing of gas;a piezoelectric unit fitted in said piezoelectric unit casing for generating piezoelectricity, wherein said piezoelectric unit comprises a movable operating part upwardly extended from said pusher cavity and an ignition tip connected thereto;a pusher cap slidably fitted in said pusher cavity of said casing in a vertically movable manner, wherein said pusher cap is attached to a top end of said piezoelectric unit and comprises a cap body and a pusher head attaching on top of said cap body and exposing above said piezoelectric unit casing; anda safety device comprising a locking stopper disposed between said pusher head and said locking flange in an inwardly movable manner, and a resilient unit mounted between said locking stopper and said pusher cap to normally urge and retain said locking stopper positioning between said pusher head and said locking flange of said piezoelectric unit casing, so as to block any downwardly movement of said pusher cap and thus prevent ignition operation of said piezoelectric unit unless said locking stopper is pressed to move inwardly away from said locking flange.
