Abstract
When a cap of a cigarette lighter is opened, fuel is mixed in a gasified state with externally drawn air, and the resultant mixture of air and gasified fuel is supplied to a catalyst within the lighter body for causing natural combustion of the mixture by the oxidizing action to elevate the temperature of the air-fuel mixture to the ignition point so as to bring about ignition.
Claims11
A fuel gas lighter of the type using a catalyst to elevate the temperature of at least a portion of the gas flow to ignition temperature comprising:
- (a) fuel storage means in said lighter;
- (b) a nozzle;
- (c) control means for controlling the flow of fuel to said nozzle;
- (d) conduit means for delivering the fuel from said control means to said nozzle;
- (e) means in said conduit means for gasifying the fuel;
- (f) said means for gasifying comprising at least one restricting and expanding means;
- (g) suction means in said conduit means actuated by the flow of fuel therein for drawing in air and mixing said air and fuel together;
- and
- (h) a catalyst mounted within said lighter
- (i) means for passing at least part of said fuel and air mixture in contact with said catalyst whereby the temperature of the fuel and air mixture is raised to ignition temperature.
