Description

BACKGROUND

The present invention relates to a hair iron, and more particularly, to a hair iron heating upper and lower heating plates through upper and lower heaters according to supplying of power to style hair through a holding operation of the heated upper and lower heating plates, in which the upper and lower heating plates include iron removing members to attract and remove a foreign substance such as iron attached to hair, thus preventing the damage of hair due to a foreign substance and achieving efficient hair styling, so as to satisfy customers or users.

Generally, hair irons are used in hairdressers' shops such as beauty salons and barbershops to heat hair for hairdressing such as waving, straightening, and curling. Such hair irons have been developed in various shapes.

FIG. 1 is a perspective view illustrating a hair iron in the related art. Referring to FIG. 1, an upper case 5 and a lower case I are hinged to each other, and the lower case 1 includes a lower grill part 2 handled by a hand, and a lower heating part 3 in a single body through injection molding. The lower heating part 3 includes a built-in lower heater (not shown).

The front end of the lower case 1 is provided with a lower heating plate 4 that is moved according to the amount of hair and in surface contact with the hair to heat the hair. The upper case 5 is coupled with the lower case 1, and includes an upper grill part 6 and an upper heating part 7 in a single body through injection molding. The upper heating part 7 includes a built-in upper heater (not shown). The front end of the upper case 5 is provided with an upper heating plate 8 that is moved according to the amount of hair and in surface contact with the hair to heat the hair.

The upper and lower heating plates 8 and 4 may have various shapes such as a flat plate shape, a triangular shape, a circular shape, a semi-circular shape, and a combination thereof or have an essentially π-shaped cross-section. Hair is styled using the hair iron by inserting a power plug connected to a power wire into a plug receptacle, and then, by heating the upper and lower heaters by the upper and lower heating plates 8 and 4, and simultaneously, by sliding the upper and lower heating plates 8 and 4 on the hair in the state where the hair is held by the upper and lower heating plates 8 and 4, and, by applying heat generated from the upper and lower heaters to the hair.

The upper and lower heating plates 8 and 4 typically include rectangular heating parts, and the upper and lower heating plates 8 and 4 are fabricated by extruding aluminum (Al) or jade, and then, by coating them with material such as Teflon coating material, anodizing coating material, and ceramic coating material. In this case, while the hair iron is used, foreign substances such as various heavy metals attached from air to the hair iron are not removed. Rather, the hair iron brings the foreign substances in closer contact with the hair, thus damaging the hair.

On the other hand, various hair irons has been developed for heath. Especially, a hair iron with magnets is disclosed in US patent publication No. 2006/0207625. According to the US patent publication, the magnets are disposed on corresponding styling heads so that the magnetic polarity of the magnetic field appearing on the pair of corresponding contact styling surfaces are the same, the styling effects are better. Also, to further make use of the advantage of magnetism on human boy, a negative magnetism or negative magnetic polarity as known to therapeutic applications is employed to appear on the contact styling surface. Because of like magnetic polarity on the contact styling surface, the pair of styling heads is repulsive to each other. However, in the US patent publication, the magnets are not used to remove a foreign substance from hair, but just used to implement well-known therapeutic effects with the repulsion caused by the same magnetic polarity.

Especially, when a foreign substance such as iron is attached to hair, the foreign substance reacts with permanent wave liquid or dye. This makes it difficult to perform desired hairdressing and satisfy customers or users.
