  • Patent number: 6537062
    Abstract: A windproof lighter includes a gas directing arrangement including a torch nozzle, a gas nozzle, and a gas directing unit including a torch directing conduit and a gas directing conduit for directing a flow of gas toward the torch nozzle and the gas nozzle respectively. A gas detouring unit is movably mounted to the casing to block up the flow of gas passing through the gas directing conduit while the torch directing conduit is remained open. An ignition system installed into the casing for producing sparks directed toward the gas nozzle to ignite the gas emitted from the gas nozzle to provide a visible flame, so as to ignite the gas emitted from the torch nozzle to provide a torch flame. Therefore, the lighter is capable of providing the torch and visible flames at the same time and providing only the torch flame while operating the gas detouring unit.

  • Publication number: 20030022119
    Abstract: A multi-flame lighter which comprises of a housing, an ignition mean, a fuel housing containing combustible liquid fuel, a valve, a connecting tube, an adjustable valve, a vaporizer, a mixing chamber, a nozzle, and a flame chamber. The present invention requires far fewer parts than any existing lighters that can produce multiple flames. The present invention has a simple design and can be manufactured easily at a consistent quality. The manufacturing and parts cost of the present invention is much lower than the existing lighters that can produce multiple flames due to the single valve, connecting tube, single adjustable valve, single vaporizer, single mixing chamber, and single nozzle configuration. The multi-flame lighter produces multiple clearly visible flames that are both aesthetically pleasing and functional. The multiple visible and forceful flames are equivalent to 2 or more of the flames from a conventional lighter and are wind resistant.

  • Publication number: 20020197579
    Abstract: A lighter of multiple torch flames comprises a nozzle and vaporizer assembly that includes a vaporizer, a mixing chamber, and at least two burner nozzle channels generally in V-orientation. The vaporizer has at least one central opening and a filter below the opening, thereby generating a burst of clean vaporized combustible gas to pass through a path toward the burner nozzle channels. The mixing chamber has at least one air inlet where the combustible gas is mixed with fresh air. The nozzle channels have a joint point within a stabilizing chamber of a diameter smaller than that of the path, thereby directing the few combustible gas to diversion channels to form a ring of surrounding flames and most toward the nozzle channels to form at least two forceful and distinct torch flames in straight column shape when being ignited.

  • Publication number: 20020187446
    Abstract: A torch lighter includes a fuel nozzle assembly provided for vaporizing the fuel released therefrom to a high-pressured gaseous fuel to emit to the ignition chamber, wherein the vaporizer assembly includes a torch head, which is provided at an emitting end of a nozzle body and supported within a combustion housing, having a root chamber having a size larger than the size of the emitting end of the nozzle body to form a gas stabilizing reservoir to ensure a collective and stable flow of the mixture gas, and two or more elongated nozzle ducts each having an ignition end and a root end extended to a ceiling of the root chamber, wherein a mixture gas ejected from the two ignition ends is ignited in the ignition chamber to form two torches soaring away from the two ignition ends of the two nozzle ducts.
