Abstract
A butane burner for personal care appliances includes a receptacle at one end for a gas canister. Upon insertion of a canister, a probe presses against the canister valve, opening it; and it thereafter remains open. Gas then flows to the input end of the control stem and, depending upon the longitudinal positioning of the control stem, flows into the stem through a gas inlet orifice in one side of the stem and travels in a channel within the stem to an outlet orifice at the other end. There it enters a Venturi, is mixed with air, passes from there through a mixing chamber and to a burning chamber within the barrel of the curling iron. The catalytic burner is located in the burning chamber. The control stem is spring-pressed in a direction to keep the gas inlet orifice normally in the open position. Movement of the control stem a slight distance in a direction away from the canister and toward the Venturi blocks the gas inlet orifice and stops gas flow. This movement can be caused by movement of a shut-off cam, or by the action of a pressure regulator.
