Description SINGEING HAIR CUTTER

Technical Field

[1] The present invention generally relates to a beauty scissor for hair cutting, and more particularly, to a singeing hair cutter for preventing damage to hair. The singeing hair cutter according to the present invention provides a scissor having a pair of heat- emitting plate blades which are capable of cutting hair by scorching the hair, instead of conventional metal cutting-blades. Background Art

[2] Today, most people adorn themselves. In particular, with interest in hair styles, they have their hair done such that they get perms or hair cuts, or dye their hair. During such a hair-styling process, damage to hair may be caused. FIG. 1 illustrates the cross section of human hair. Human hair is composed of cortices 3, medullas 4, and cuticles 5. The cuticles 5 cover the surface of the hair and protect the inside of the hair with their strong chemical resistance. The cuticles 5 have a scalelike shape in which several sheets of cornificated flat non-nuclear cells sequentially overlap. The cortices 3 are groups of dead cortex cells and occupy most of the hair. The main component of the cortices 3 is keratin protein.

[3] However, the cuticles 5 are inevitably cracked during hair cutting. Moreover, when exposed to a chemical material, e.g., during a dyeing or perm process, a damage process progresses in which the cuticles 5 are split and thus keratin of the cortices 3 is cracked and comes out, resulting in evaporation of the medullas. The damaged hair has much damage especially in its end, and such damage propagates to the follicle and root of the hair, aggravating the hair damage.

[4] FIG. 2 illustrates the cross section of damaged hair and damaged cuticles 5.

Referring to FIG. 2, once the hair is damaged, holes are generated in the cross section of the cuticles 5, causing damage to the cuticles 5. Disclosure of Invention

Technical Problem

[5] An object of the present invention is to provide a beauty scissor which is capable of cutting hair without causing damage to the hair. [6] Another object of the present invention is to provide a beauty scissor which is capable of promoting hair damage prevention and hair care effects by preventing the nutrition of the hair from leaking out. [7] A third object of the present invention is to provide a beauty scissor which is capable of preventing hair from falling out by improving head skin.

Technical Solution

[8] To achieve the aforementioned goals, the present invention uses a singe technique that cuts hair by scorching the end of the hair. To this end, in a singeing hair cutter according to the present invention, heat-emitting plate blades are mounted in inner faces of a pair of blades (a moving blade and a still blade) that intersect with each other by performing lever movements around a pivot point, and hair is cut by a singeing effect in which the hair is cut by being scorched by heat emitted from the heat-emitting plate blades mounted in the inner faces of the moving blade and the still blade when the moving blade performs a pivot movement with respect to the still blade around the pivot point for hair cutting.

[9] The singeing hair cutter according to the present invention is structure such that the moving blade and the still blade perform a pivot movement around the pivot point and the moving blade includes a thumb grip and the still blade includes a finger grip. The heat-emitting blades are fixed by covers and a screw in the inner faces of the moving blade and the still blade, and the amount of singed heat is controlled by controlling the power supply to the heat-emitting blades by means of a control unit.

[14] Hereinafter, a preferred embodiment of the present invention will be described with reference to the annexed FIGs. 3 and 4.

[15] FIG. 3 schematically illustrates the structure of a singeing hair cutter according to a preferred embodiment of the present invention. First, the present inventor gives names to components of the singeing hair cutter to facilitate understanding of the structure of the singeing hair cutter according to the present invention. Referring to FIG. 3, for a singeing effect that cuts hair by scorching the hair, the singeing hair cutter according to the present invention includes heat-emitting plate blades 11 and 14, instead of metal blades having sharp cutting portions.

[16] In other words, the heat-emitting plate blades 11 and 14 of the singeing hair cutter according to the present invention are heated in a range of 200 - 35O ⁰ C in order to cut the hair by means of the singeing effect. In other words, the heat-emitting plate blades 11 and 14 of the singeing hair cutter according to the present invention provide means

for cutting the hair by scorching the end of the hair while preventing damage to the hair after being heated in a range of 200 - 35O ⁰ C.

[17] Referring back to FIG. 3, the heat-emitting plate blades 11 and 14 of the singeing hair cutter according to the present invention may be implemented with a ceramic material and are connected with electric wires 15 and 16 inserted through the internal spaces of a thumb grip 12 and a finger grip 10 for power supply. The heat-emitting plate blades 11 and 14 of the singeing hair cutter according to the present invention may also be mounted in inner faces of a moving blade 54 and a still blade 55, which intersect with each other during a pivot movement of the moving blade 54 and the still blade 55.

[18] The singeing hair cutter according to the present invention includes a control unit

20 for controlling power supply. The control unit 20 turns on and off power and controls the temperatures of the heat-emitting plate blades 11 and 14.

[19] FIG. 4 is an exploded view of components of the singeing hair cutter according to the preferred embodiment of the present invention. Referring to FIG. 4, in the heating- type beauty scissor according to the present invention, the still blade 55 having the heat-emitting plate blade 11 mounted in its inner face and the moving blade 54 having the heat-emitting plate blade 14 mounted in its inner face are screw-coupled to each other with respect to a pivot point 13. The moving blade 54 is connected to the thumb grip 12 and the still blade 55 is connected to the finger grip 10.

[20] The heat-emitting plate blades 14 and 11 are supplied with power through the electric wires 16 and 15, respectively, and the moving blade 54 and the still blade 55 may be made of high-strength plastic. The heat-emitting plate blades 14 and 11 may be firmly fixed onto the moving blade 54 and the still blade 55 of the scissor by means of a screw 63 while being covered with fixing covers 42 and 41, respectively.

[21] It is preferable that the electric wires 15 and 16 for supplying power to the heat- emitting plate blades 11 and 14 are mounted in the inner spaces of the thumb grip 12 and the finger grip 10, and the ends of the electric wires 15 and 16 are terminated by a connector 31 at the end of the finger grip 10. Preferably, the end of the finger grip 10 includes the connector 31 for power supply controlled by the control unit 20 and may take the form of a power supply connector device that is commonly used. The control unit 20 of the beauty scissor according to the present invention may include an on/off switch and a temperature-adjusting lever 26.
