Abstract

Abstract A hair styler for winding hair thereon for curling, comprising a hollow sealed tubular member made of a metallic material having good thermal conductivity and defining a heat pipe having a heat dissipating hair winding portion. The tubular member contains a charge of a working fluid vaporizable at an operating temperature of 50° C. to 70° C. The outer surface of the heat dissipating portion of the heat pipe is covered with an elastic hair engagement member for preventing hair slippage. The heat receiving end portion of the heat pipe is exposed so as to be adapted to receive heat from a separate external heat source having a temperature range of 50° C. to 120° C. Thereby hair wound around the outer surface of the heat dissipating portion of the heat pipe forming the bobbin is heated by the condensation of the vaporized working fluid within the heat pipe.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 153 words
A hair styler for winding hair thereon for curling, comprising a hollow sealed tubular member made of a metallic material hving good thermal conductivity and defining a heat pipe having a heat dissipating hair winding portion and containing a charge of a working fluid vaporizable at an operating temperature of 50° C. to 70° C., the outer surface of the heat pipe being covered with an elastic hair engagement member for preventing hair slippage, and covering the outer surface of the heat dissipating portion of the heat pipe while leaving the heat receiving end portion exposed so as to be adapted to receive heat from a separate external heat source having a temperature range of 50° C. to 120° C. whereby heat wound around the outer surface of the heat dissipating portion of the heat pipe forming the bobbin is heated by the condensation of the vaporized working fluid within the heat pipe.
Claim 2
Dependent Claim 153 words
A hair styler for winding hair thereon for curling, comprising a hollow sealed tubular member made of a metallic material hving good thermal conductivity and defining a heat pipe having a heat dissipating hair winding portion and containing a charge of a working fluid vaporizable at an operating temperature of 50° C. to 70° C., the outer surface of the heat pipe being covered with an elastic hair engagement member for preventing hair slippage, and covering the outer surface of the heat dissipating portion of the heat pipe while leaving the heat receiving end portion exposed so as to be adapted to receive heat from a separate external heat source having a temperature range of 50° C. to 120° C. whereby heat wound around the outer surface of the heat dissipating portion of the heat pipe forming the bobbin is heated by the condensation of the vaporized working fluid within the heat pipe.
Claim 3
Dependent Claim 53 words
A hair styler according to claim 1, wherein the elastic hair engagement member is provided over the outer surface of the heat pipe in such a manner that hair wound on the heat pipe is partly directly brought into contact with the outer surface of the heat dissipation portion of said heat pipe.
