Abstract:
1. A lighter, comprising: a casing having a receiving cavity and a top opening communicating said receiving cavity with outside, wherein said casing comprises a supporting platform rigidly supported in said receiving cavity and a pusher button is mounted on said casing in a vertically movable manner; a gas emitting nozzle appearing at a ceiling of said casing; a fuel supply arrangement, comprising: a replaceable fuel cartridge slidably received in said receiving cavity through said top opening in a detachably mounting manner for storing a liquefied fuel; a gas releasable valve, which is substantially supported on said supporting platform to communicate with the gas emitting nozzle, comprising a tubular inserting adapter extended downwardly for communicating said fuel in said replaceable fuel cartridge for controlling a flow of gas from said replaceable fuel cartridge to said gas emitting nozzle through a flexible gas tube, wherein said tubular inserting adapter is sealedly inserted into said replaceable fuel cartridge so as to detachably connect with said replaceable fuel cartridge; and a lever arm, which is supported in said casing in a pivotally movable manner, having an actuating end coupling with said gas releasable valve and a driving end arranged in such a manner that when said pusher button is pressed downwardly to depress said driving end, said actuating end lifts up said gas releasable valve for releasing said fuel in said replaceable fuel cartridge to said gas emitting nozzle through said flexible gas tube of said gas releasable valve; and an ignition system comprising a piezoelectric unit supported by said casing for producing a spark toward said gas emitting nozzle to ignite said gas emitted from said gas emitting nozzle simultaneously when said pusher button is pressed downwardly to compress said piezoelectric unit.
