Steam curling iron having interchangeable hair winding mandrels

A hair device comprising:

• a tubular barrel having first and second ends and a predetermined cross-sectional configuration;
• heat and vapor generating means within said barrel for heating said barrel and for producing vapor in said barrel;
• a plurality of apertures through said barrel for conveying vapor out of said barrel, said apertures being located in spaced relation around said barrel;
• a handle portion extending from the first end of the tubular barrel;
• a mandrel for winding hair therearound, said mandrel cross sectional area exceeding that of the tubular barrel, wherein said mandrel is removably received over the barrel for replacement by a simularly constructed mandrel having a different hair engaging surface, and wherein said mandrel is generally tubular in configuration about a longitudinal axis, has first and second ends and inner and outer surfaces;
• a plurality of passages through the mandrel;
• and
• a plurality of resilient fins arranged in pairs to form ducts therebetween which register with the passages in the mandrel, wherein the fins extend from the inner surface of the mandrel toward the barrel and engage the barrel to hold the mandrel in spaced relation with the barrel, and wherein the fins engage the barrel adjacent the apertures of the barrel with the apertures aligned with the ducts so that the vapor in the barrel passes through the ducts and through the passages in the mandrel while the heat is conducted by the fins to the mandrel, whereby hair wound around the outer surface of mandrel is treated with heat and vapor.
