Abstract
An electrical ignition device for a gas-powered catalytic curling iron. A self-contained electrical ignition device, including a battery, is provided in the top of the curling iron. When a spring loaded button member is depressed, electrical contact is made between the battery and an incandescent filament, such as a platinum wire. The filament is proximate a catalytic heating means. When the filament is activated, oxidation of the vaporized fuel/air mixture, in the presence of the catalyst, is initiated.
Claims3
In a curling device having a tubular body defining a heating chamber therein, and having first and second ends and a hair winding portion disposed between the first and second ends and surrounding the heating chamber, heating means including a catalyst means disposed in the heating chamber, a housing member proximate the tubular body including fuel supply means for storing a fuel in a liquid state, and aspirating means coupled between the fuel supply means and the heating chamber for varporizing the fuel and for mixing the vaporized fuel with air and for supplying a vaporized fuel/air mixture to said catalyst means, the improvement comprising:
- self-contained electrical ignition means mounted in the first end of the tubular body proximate the catalyst means for initiating oxidation of the vaporized fuel/air mixture in the presence of the catalyst means, said electrical ignition means including:
- a battery mounted in said electrical ignition means;
- an accessable electrically non-conductive movable button member affixed in the tip of said first end of said tubular body;
- an electrically movable conductive means, movable with said button member and located between said button member and said battery;
- an electrically conductive spring member located between said battery and said electrically movable conductive means;
- an incandescent filament, proximate said catalyst means, for oxidizing the vaporized fuel/air mixture in the presence of said catalyst means;
- and
- a stationary electrically conductive means providing an electrical connection between said battery and said incandescent filament, wherein said electrically conductive spring member provides a biasing force to said electrically movable conductive means to prevent an electrical connection between said movable conductive means and said stationary conductive means unless said button member is moved a predetermined distance in a longitudinal direction of the device against the force of said spring member, when said button member is moved the predetermined distance, an electrical connection is made between said battery, spring member and said movable electrically conductive means and said stationary electrically conductive means, thereby electrically activating said incandescent filament.
