A portable curling iron having a barrel to be heated, includes first and second burners which heat the barrel; a fuel supply cartridge which supplies fuel to the first and second burners, the cartridge including a fuel delivery valve which controls the flow of fuel from the cartridge; a plunger which applies a force to the valve in response to user actuation, to start the flow of fuel from the cartridge; a regulator assembly including a diaphragm which applies a reverse force to the plunger when the gas pressure exceeds a predetermined pressure, to maintain a substantially constant flow rate of fuel to the first and second burners; a valve stem through which the fuel travels from the cartridge to the second burner; a bimetallic element for applying a force to the valve stem to permit the fuel to pass to the second burner when the temperature is less than a predetermined start-up temperature and for removing such force when the predetermined start-up temperature is attained; and a spring which applies a reverse force to the valve stem to prevent the fuel to pass to the second burner when the predetermined start-up temperature is attained, so as to achieve fast heat up of the barrel without fuel waste.

Portable heating appliance

A portable hair roller heating device for heating flexible hair rollers, includes an enclosed heating chamber defined by a top wall, side wall and bottom wall, the top wall having a plurality of apertures through which the hair rollers to be heated can be inserted; a cover hingedly connected on the top wall so as to cover portions of the hair rollers extending through the top wall; first and second burners positioned adjacent the heating chamber, the first burner having a first burner tube with a free end and the second burner having a second burner tube with a free end; a single junction tube joining together the free ends of the first and second burner tubes, the junction tube having a free end extending into the chamber for heating the same; a fuel supply cartridge which supplies fuel to the burners and which controls the flow of fuel from the cartridge, the cartridge including a fuel supply valve; an ignitor assembly for igniting the fuel escaping from the free end of said junction tube; and a plunger which applies a force to the valve in response to user actuation, to start fuel flow.
