Abstract:
1. A lighter, comprising: a casing having a receiving cavity and an opening communicating said receiving cavity with outside; a gas emitting nozzle appearing at a ceiling of said casing; an ignition system supported by said casing for producing a spark toward said gas emitting nozzle; two substantially rigid guiding walls supported within said casing, wherein each of said guiding walls has a transverse stopper ridge rigidly and integrally and inwardly defined thereon; and a fuel supply arrangement, which comprises: a replaceable fuel cartridge detachably received in said receiving cavity through said opening for storing a liquefied fuel, wherein said replaceable fuel cartridge comprises a gas releasable valve coupling with said gas emitting nozzle for controlling a gas flow from said replaceable fuel cartridge; a gas releasing lever, which is pivotally mounted on said replaceable fuel cartridge, having an actuating end coupled to said gas releasable valve for shifting a movement of said gas releasable valve and a driving end arranged when said driving end is depressed, said actuating end is pivotally actuated to shift said gas releasable valve for releasing said liquefied fuel from said replaceable fuel cartridge; a gas releasing arrangement comprising an actuator movably supported within said casing to engage with said driving end of said gas releasing lever in such a manner that when said actuator is moved to depress said driving end of said gas releasing lever, said gas releasable valve releases gas to said gas emitting nozzle for being ignited; a sheltering cap movably supported within said casing to detachably couple with said gas releasable valve when said replaceable fuel cartridge received in said receiving cavity, wherein said sheltering cap is slidably mounted between said guiding walls such that said guiding walls guides a movement of said sheltering cap when said sheltering cap is upwardly pushed by said gas releasable valve, wherein when said gas releasing valve is lifted up to push said sheltering cap upwardly, said stopper ridges block a further upward movement of said sheltering cap, wherein said sheltering cap further has a cap shoulder circularly projected from an outer wall of said sheltering cap, so that when said sheltering cap is upwardly shifted, said stopper ridges is arranged to bias against said cap shoulder so as to block said further upward movement of said sheltering cap; and at least a resilient member disposed between said transverse stopper ridge and said cap shoulder, wherein when said sheltering cap is upwardly shifted, said resilient member is squeezed between said stopper ridge and said cap shoulder so as to generate a biasing force facilitating said cap shoulder disengage with said stopper ridge after said actuator is released.
