Abstract
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.
