Abstract:
An adjustable jet flame utility lighter, comprising:a casing having a liquefied gas storage, a gas emitting nozzle appearing at a ceiling of said casing and communicating with said liquefied gas storage in said casing, a piezoelectric unit, which is disposed in said casing for generating piezoelectricity, comprising an igniting tip extended adjacent to said gas emitting nozzle; a pusher button slidably mounted on said ceiling of said casing in a vertically movable manner, wherein when said pusher button is depressed downwards to a depression position, said pusher button both opens a valve of said gas emitting nozzle to provide a flow of gas emitted from said emitting nozzle and operates said piezoelectric unit to generate sparks to ignite said flow of gas emitted from said gas emitting nozzle to produce a jet flame at said emitting nozzle; a holding means, mounted on the casing, for holding said pusher button at said depression position so as to retain said adjustable jet flame utility lighter in an ignition position to continuously produce said jet flame; and a hand operative adjustable button rotatably mounted on said casing for controlling said flow of gas through said gas emitting nozzle, wherein said hand operative adjustable button is an enlarged button having a diameter equal to or larger than a width of said casing, wherein by retaining said depression position of said adjustable jet flame utility lighter with said holding means, a size of said jet flame is able to be adjusted by controlling said flow of said gas by turning said hand operative adjustable button by hand while observing a change of size of said jet flame during operation.
