SACKGRt7DND OF THE xNVEIQTION
1. Field of the Invention The present invention relates to a hair styling product.
In particular, the present invention relates to hand-held, electrically heated devices for heating, and manipulating and/or curling hair. More particularly, the present invention relates to a hair curling iron device that curls hair and additionally uses hot air to dz~y hair. Most particularly, the present invention relates to hair irons, such as curling irons and brush irons, that employ a barrel to heat hair disposed or manipulated about the barrel, and additionally blowing hot air to simultaneously dry hair.
2. Description of the Prior Axt Customarily, users o;~ such styling products require clean hair that is also dry to achieve th.e best styling results.
Therefore, the hair has to be washed, blown, then styled. Some users have combined the styling with drying o~ hair by using a.
blow dryer_ while simultaneously usa.ng a brush to curl. However, this is a di~f_icult task and is predominantly a technique performed at hair salons. Thus, there is a growing need for 833.OJ,63USU
hair care devices that are convenient, portable, easily manipulated and provide professional styling results.
Ha~.r manipulating devices that employ an iron, i.e., a tube or barrel, to heat a.nd manipulate hair_ are well known. Such devices include curling irons, thermal hot air ~.rons and brush ~.rons. Curling irons and some brush irons employ one or more types of heating elements in the barrel to heat the barrel.
Examples of such heating elements include a rope heater, i.e., a resistance heater wound on a glass rope and loopEd inside the barrel, a resistance wire wound on mica and he7.d between metal springs inside the barrel, and a ceramic heater suspended in the barrel between metal, contacts and spr~.ngs. These heating elements commonly extend through and fill the central portion of the barrel. In brush irons, the barrel. wall has holes in it and a tooth bar ~.s disposed in the barred. between the heating element and the barrel wall so that teeth o~ the tooth bar extend through the holes. However, heating the barrel from its central portion does not provide for rapid initial. heat~.ng of the barrel and. is not fully efficient. A thermal hot air iron drives hot air through a barrel and through holes inn the wall of the barrel.

U.S. Patent No. 5,994,059 describes a hair curling iron that includes an air heater and a blower disposed in the handle portion of the curling ~.ron. ~ steam generator is disposed in the barrel that extends from the handle portion. This patent provides for the presence of a water ~ontainex located in the baz~rel portion so as to enable steam to be generated from the barrel portion. The present invention does not include a water container, yet combines heat and air for curling and drying of hair.
U.S. Patent No. 5,365,037 describes a hand-held electric curJ.ing iron whose barrel is adapted to selectively join one of a plurality of different diameter hair xollers. The handle portion includes a fan, and the barrel portion includes a plurality of apertures that enable heated air to be directed onto a roller pos~.tioned about the barrel. In contrast, a hair roller does not adapt onto the present device, but rather directly and conveniently styles hair using its barrel portion.
U.S. Patent No. 4,935,027 describes a hair dryer/steamer combination that includes a handle and a barrel portion. The handle includes a blower and a heater for heating air.. The heated air i_s blown into the barrel and exits from apertures therein. The barrel portion inc7.udes a separate heater and ' ~ ' ~..~ 'i ~ 833.0163USU
water reservoir to enable steam to be produced and carried out by the air flow. The pxesent invention does not have a water reservoir in its barrel portion for a steaming function.
Instead, the air blown from the barrel of the present invention is dry aix for quick drying of hair while styling.
U.S. Patent No. 4,602,143 describes a curling iron that includes an infrared radiation source within a hollow barrel.
The baxrel is substantially transparent to the IR radiation.
The handle portion includes a fan fox blowing air over the IR
radiation source and out of apertures located at the distal end of the barrel. The pxesent ~.nvEntion does not have an infxared rad~.ation source for heated ai,x.
Th'e present invention provides an improved deva.ce that not only has a hot barrel fox styling hazy, but also simultaneously blows hot air to dry hair.
