Abstract:
A disposable lighter, comprising:a gas casing receiving a fuel storage, wherein said gas casing has a receiving chamber provided on a lower portion of a sidewall of said gas casing and a through slot extended from said receiving chamber to a ceiling of said gas casing; a gas emitting nozzle having an ignition tip appearing at said ceiling of said gas casing and communicating with said fuel storage for controlling a flow of gas, wherein said gas emitting nozzle further comprises a gas releasable valve and a gas lever having an engaging end engaged with said gas releasable valve and an actuating end arranged in such a manner that when said actuating end of said gas lever is depressed downwardly, said engaging end of said gas lever pivotally lifts up said gas releasable valve to release said gas from said fuel storage through said ignition tip; a piezoelectric unit comprising a main piezoelectric body, a movable operating part slidably extended therefrom, and a spark generating tip extended to a position close to said ignition tip of said gas emitting nozzle, wherein when said movable operating part is depressed with respect to said main piezoelectric body, said spark generating tip generates sparks to ignite said gas emitted from said ignition tip of said gas emitting nozzle, wherein said piezoelectric unit is received in said receiving chamber and said spark generating tip is extended through said through slot towards said ignition tip of said gas emitting nozzle; an outer shelter slidably mounted on said sidewall of said gas casing and defining a receiving cavity between said outer shelter and said gas casing wherein said piezoelectric unit is received in said receiving cavity, wherein said outer shelter is constructed as a tubular sleeve having a shape and size encirclingly mounted on a lower portion of said sidewall of said gas casing in an axially and slidably movable manner, so as to enclose said receiving chamber of said gas casing; and an actuating arm extended from an inner side of said outer shelter to a top end of said piezoelectric unit in such a manner that when said outer shelter is axially slid with respect to said gas casing, said actuating arm is driven to compress said piezoelectric unit so as to ignite said disposable lighter.
