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.

Dependent claims

A windproof lighter, comprising:

a supporting frame comprising a casing having a liquefied gas storage and a lever arm, having a lifting end and a depressible end, pivotally supported in said casing;
a gas directing arrangement, comprising:
a gas releasable valve extended from the liquefied gas storage for controlling a flow of gas from the liquefied gas storage wherein said lifting end of said lever arm is engaged with said gas releasable valve in such a manner that when said depressible end of said lever arm is depressed downwardly, said lifting end of said lever arm lifts up said gas releasable valve for releasing said flow of gas from said liquefied gas storage;
a torch nozzle receiving in a nozzle housing and appearing from a ceiling of said casing;
a gas nozzle positioned adjacent to said torch nozzle at a position at least 2 mm below a ceiling of said nozzle housing of said torch nozzle;
a gas directing unit comprising a torch directing conduit extended from said gas releasable valve to said torch nozzle for directing said flow of gas toward said torch nozzle and a gas directing conduit extended from said gas releasable valve to said gas nozzle for directing said flow of gas toward said gas nozzle;
and
a gas detouring unit mounted to said casing in a movable manner;
and
an ignition system installed into said supporting frame for producing sparks towards said gas nozzle to ignite said flow of gas emitted from said gas nozzle for providing a visible flame so as to ignite said flow of gas emitted from said torch nozzle for producing a torch flame, wherein said gas detouring unit is adapted to move to a position to block said flow of gas passing through said gas directing conduit while said torch directing conduit is remained open in such a manner that said flow of gas passing from gas releasable valve is selectively detoured to said gas nozzle for producing said visible flame and to said torch nozzle for producing said torch flame.

a gas releasable valve extended from said liquefied gas storage for controlling a flow of gas from said liquefied gas storage wherein said lifting end of said lever arm is engaged with said gas releasable vale in such a manner that when said depressible end of said lever arm is depressed downwardly, said lifting end of said lever arm lifts up said gas releasable valve for releasing said flow of gas from said liquefied gas storage;
a torch nozzle receiving in a nozzle housing and appearing from a ceiling of said casing;
a gas nozzle positioned adjacent to said torch nozzle at a position at least 2 mm below a ceiling of said nozzle housing of said torch nozzle;
a gas directing unit comprising a torch directing conduit extended from said gas releasable valve to said torch nozzle for directing said flow of gas toward said torch nozzle and a gas directing conduit extended from said gas releasable valve to said gas nozzle for directing said flow of gas toward said gas nozzle;
and
a gas detouring unit mounted to said casing in a movable manner and arranged to move to a position to block said flow of gas passing through said gas directing conduit while said torch directing conduit is remained open;
and
an ignition system, installed into said supporting frame for producing sparks towards said gas nozzle to ignite said flow of gas emitted from said gas nozzle for providing a visible flame to ignite said flow of gas emitted from said torch nozzle for providing a windproof torch flame, wherein said windproof torch flame is arranged to re-ignite said visible flame when said visible flame is blown out.

A windproof lighter, comprising:

a supporting frame comprising a casing having a liquefied gas storage;
a gas directing arrangement, comprising a gas releasable valve extended from the liquefied gas storage, a torch nozzle receiving in a nozzle housing and appearing from a ceiling of said casing, a gas nozzle positioned adjacent to said torch nozzle at a position at least 2 mm below a ceiling of said nozzle housing of said torch nozzle, and a gas directing unit comprising a torch directing conduit extended from said gas releasable valve to said torch nozzle for directing said flow of gas toward said torch nozzle and a gas directing conduit extended from said gas releasable valve to said gas nozzle for directing said flow of gas toward said gas nozzle;
and
an ignition system, comprising:
a flint supported by said supporting frame, and
a striker wheel having a circumferential coarse striking surface positioned in contact with said flint, wherein said flint is retained urging against said striking surface of said striker wheel for producing sparks directed toward said gas nozzle when said striking surface is driven to strike against said flint, such that said flow of gas emitted from said gas nozzle is ignited to provide a visible flame which functions as a flame igniter, so as to ignite said flow of gas emitted from said torch nozzle to provide a torch flame.
