Abstract:
1. A torch lighter, comprising: a casing having a liquefied fuel storage and a fuel valve which is actuated by a fuel lever pivotally mounted in said casing for releasing fuel therefrom; an ignition unit generating sparks directed toward an ignition chamber; and a fuel nozzle assembly provided for vaporizing said fuel released from said fuel valve to a high-pressured gaseous fuel to emit to said ignition chamber, wherein said fuel nozzle assembly comprises: a nozzle body having a root opening, an emitting opening, and at least an air inlet provided thereon, wherein said air inlet is positioned adjacent to said rooting opening to define an elongated mixing chamber axially extended between said air inlet and said emitting opening, wherein said mix chamber has a diameter sized between 1 mm to 2.5 mm and a flow of air is capable of inletting into said mixing chamber through said air inlet; a torch nozzle, which is coaxially connected between said root opening of said nozzle body and said fuel valve, having a micro nozzle pore having a diameter of 0.05 mm to 0.12 mm and comprising a mesh filter provided below said nozzle pore for preventing residual particles of said fuel from entering said nozzle body, wherein said fuel released from said fuel valve is vaporized into a strong, pressurized gaseous fuel jetting into said mix chamber, wherein said jetting gaseous fuel and said air flowing through mix chamber are mixed to form a mixture gas at said emitting opening of said nozzle body; a combustion housing which is supported around said emitting opening of said nozzle body and defines said ignition chamber therein; and a torch head, which is provided at said emitting opening of said nozzle body and supported within said combustion housing, having: a root chamber, P a torch stabilizing arrangement has a plurality of diversion emitting openings formed at said upper portions of said nozzle ducts for providing a stable environment root flame for igniting said mixture gas ejected from said ignition ends of said nozzle ducts to form two or more spaced torches and stabilizing and holding said spaced torches to form a strong and stable group of said torches, wherein said stable environment root flame has a plurality of root flames which are united and mixed with root Portions of said spaced torches.
