The present invention relates to a photoreactive hair treatment apparatus, and more particularly to a photoreactive hair treatment apparatus which emits light to hair coated with a hair treatment agent for perm, dyeing, and nutrition care, enhancing hair treatment efficiency.
In order to form a desired hairstyle shape, prevent damages to hair, and maintain hair glossy and resilient, hair may be treated such as perming, dyeing, and nutrition care. Among those hair treatments, perm is one of the most common hair treatments used to make a desired hair styling shape.
The widely-used hair perms are a normal perm and a heat perm.
The Normal perm is a hair perm for making hair to be curled by braking cysteine bonds of the hair structure. The normal perm is conducted in a manner in which hair coated with a formula, rolled around rods, and covered by a cap, and then goes through heat treatment with 35 to 39° C., and a neutralizer solution is applied to the hair rolled around the rods and left for a while.
Unlike the normal perm for making hair to be curled only using cysteine bonds, the heat perm is a hair per using hydrogen bonds which affects a hair shape most. The heat perm is conducted in a manner in which a formula is applied to the hair and rinsed after heat treatment or natural drying and then the hair is rolled around rods and goes through treatment by transferring heat, wherein the heat transferred to the hair is about 100 to 140° C. In the heat perm, the hair is unrolled from the rods and rolled again around normal rods or curl pins and then go through neutralization.
However, the normal perm may cause the hair to be tangled and dry because the normal perm is conducted with wet hair, and the heat perm may cause the hair to be dry and less resilient since the heat perm is conducted using heat.
Meanwhile, in the case of other hair treatments such as hair dying and hair nutrition care in addition to hair perm, a hair dying agent, a hair nutrient agent, and the like are applied to hair and left until effects of the corresponding agents evidently act on the hair.
As such, such hair treatments conventionally relies on the effects of the agents, and thus, hair treatment efficiency is reduced and it takes long time until the effects of the agents evidently act on hair.
The present invention provides a photoreactive hair treatment apparatus which enables the styling of a desired shape, prevention of damages to hair, and treatment of hair to be glossy and resilient, and which can reduce a treatment time of an agent used for treating hair.
In one general aspect of the present invention, there is provided a photoreactive hair treatment apparatus including a light source configured to emit light, and a power supply unit configured to supply power to the light source, and the light source may be disposed to emit the light toward hair coated with a hair treating agent.

Therefore, embodiments and drawings described herein are simply exemplary and not exhaustive, and it will be understood that various modifications and equivalents may be made to take the place of the embodiments.
Hereinafter, a photoreactive hair treatment apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Referring to
The light source 110 emits light. The light emitted from the light source 110 may be any one of near infrared light having a wavelength range of about 750 to 3000, a visible light having a wavelength range of about 380 to 780 nm, and infrared light having a wavelength range of about 10 to 397 nm. As the light source 110, a low-power high-efficiency Light Emitting Diode (LED) may be used.
The power supply unit 130 supplies power to the power source 110. The photoreactive hair treatment apparatus 100 may be used wirelessly or wirely. That is, in order to wirelessly use the photoreactive hair treatment apparatus 100, the power supply unit 130 may include a battery 131, a circuit board 133, and a power switch 135. A charge/discharge circuit of the battery 131 and a driver for driving the light source 110 may be mounted on the circuit board 133. In order to use the photoreactive hair treatment apparatus wirely, the power supply unit 130 may include a connector 137, and a power cable 139 drawn from an external power source (not shown) may be connected to the connector 137. In the case of using the photoreactive hair treatment apparatus 100 wirelessly, a charge cable (not shown) for charging the battery 131, instead of the power cable 139 for connection to the external power source, may be connected to the connector 137.
Meanwhile, the light diffusion unit 140 may be in a cylindrical shape. The light diffusion unit 150 uniformly diffuses light emitted from the light source 110. The light diffusion unit 150 may be formed of polycarbonate (PC) having properties such as impact resistance, heat resistance, weather resistance, self-extinguishing property, transparency, etc.
The light source 110 and the power supply unit 130 may be installed in the light diffusion unit 150. That is, a space for installation of the light source 110, the battery 131, and the circuit board 133 may be formed in the cylindrical light diffusion unit 150. The light source 110 may be disposed in the light diffusion unit 150 such that the light source 110 is disposed radially from the center of the light diffusion unit 150 so as to emit light in 360 degrees around the center of the light diffusion unit 150.
The photoreactive hair treatment apparatus 100 may emit light from the light source 110, and a predetermined treatment may be conducted as hair H rolled around the outer side surface of the light diffusion unit 150 reacts to the light.
In this case, a user may select a component to be contained in a hair treating agent according to a hair treatment purpose. The hair treating agent may contain at least one of a photocatalyst, a perm agent, a hair dyeing agent, or a hair nutrient agent.
That is, the hair treating agent may include the photocatalyst. The biggest advantageous effect of the photocatalyst compared to other catalysts is that reaction available only at high temperature is allowed to be occur even at room temperature. Basically, a predetermined amount of activation energy is required for any reaction. A catalyst reduces such an amount of activation energy, thereby helping a certain reaction to occur quickly. The photocatalyst plays this role efficiently so that reaction available only at high temperature is allowed to occur at room temperature. In addition, another advantageous effect of the catalyst is a capability of causing a reaction to stop at a desired time. If a general catalyst is used, a reagent is all consumed, so it is almost not possible to stop in the middle of reaction until the reaction is not possible to occur. However, if the photocatalyst is used, it is possible to stop in the middle of reaction simply by not supplying light any longer, and thus, it is useful.
The photocatalyst is catalyst that causes chemical reaction in response to introduction of light to bring effects of deodorization, anti-bacteria, antifouling, and the like. Organic materials attached to the surface of the photocatalyst cause reaction between water and oxide and generates dioxide on the surface. The generated dioxide hydroxyl radical superoxide ion causes oxidation of a different material in contact with the surface of the photocatalyst, thereby decomposing most of the organic materials into carbon dioxide and water. That is, it brings decomposition of most of malodor components in the air, and this is called deodorization. In addition, as the superoxide ion reacts to moisture in the air and generates dioxide, the superoxide may brake and eliminate a cell membrane of bacteria, fungus, and the like on a surface, bringing anti-bacteria, reduction of bacteria, and prevention of contamination. Furthermore, when the organic materials are decomposed, the photocatalyst generates anion due to oxidation and reduction reaction, and this anion brings various healthy effects, such as improving metal stability and bioactivity like breathing, facilitating cell activity, and changing body constitution.
Thus, if a hair treating agent including the photocatalyst is coated onto hair and light is introduced to the hair, deodorization, anti-bacteria, and antifouling of the hair may be achieved.
In addition, according to a hair treatment purpose, the hair treating agent may contain a photocatalyst which is mixed with a perm agent, a hair dying agent, a hair nutrient agent, and the like, or may contain the perm agent, the hair dying agent, the hair nutrient agent, and the like individually except for the photocatalyst. In the case of using a hair treating agent containing a photocatalyst mixed with a hair dying agent, a hair nutrient agent, and the like, it is possible to achieve both effects of the photocatalyst and improves effects of hair treatment, such as perm, dyeing, and nutrition care. In addition, in the case of using a hair treating agent containing a perm agent, a hair dyeing agent, and a hair nutrient agent individually except for a photocatalyst, improved effect of a corresponding hair treatment like perm, dyeing, and nutrition care using light may be expected.
Meanwhile, the light reflection unit 170 may be in a cylindrical shape having an inner diameter greater than an outer diameter of the light diffusion unit 150. Thus, a space between the light reflection unit 170 and the light diffusion unit 150 is formed. Light having passed through the light diffusion unit 150 and hair H is reflected by the light reflection unit 170. Thus, the light is prevented from being emitted to the outside the photoreactive hair treatment apparatus 100 and being lost, and the light is introduced toward the hair H again, maximizing efficiency in treating the hair H.
The light reflection unit 170 may form the exterior appearance of the photoreactive hair treatment apparatus 100. At one end and the other end of the light reflection unit 170, the power switch 135 and the connector 137 electrically connected to the circuit board 133 may be exposed to the outside. Of course, the light reflection unit 170 may be in an openable and closable structure so as to easily roll the hair H around the light diffusion unit 150 and easily unroll the hair H therefrom after completion of perming the hair H.
Meanwhile, a coating layer 151 with a photocatalyst coated thereon may be provided on an outer surface of the light diffusion unit 150.
Here, the photocatalyst is described as the coating layer 151 provided on the outer surface of the light diffusion unit 150, which is a constituent component of the photoreactive hair treatment apparatus 100. In another embodiment, although the photocatalyst is not implemented as the coating layer 151 coated on the outer surface of the light diffusion unit 150, which is a constituent component of the photoreactive hair treatment apparatus 100, it is possible to apply the photocatalyst directly to the hair H coated with a hair treating agent or apply the photocatalyst in the form of a mixture with the hair treating agent.
Meanwhile, the photoreactive hair treatment apparatus 100 includes a circuit for driving the light source 100 and power required to drive the light source 100 is supplied, and thus, the photoreactive hair treatment apparatus 100 may increase in temperature and may be possibly overheated. Thus, the photoreactive hair treatment apparatus 100 may include a temperature detector 191 for monitoring temperature of the photoreactive hair treatment apparatus 100.
In addition, the hair H tends to absorb moisture, so, when humidity is high, the hair H absorbs moisture, thereby expanding about one and a half times. In the case of a hair perm, an agent used in the perming is composed of a component that causes dehydration reaction between the hair H. If humidity is high, the hair absorbs a more amount of humidity, deteriorating a binding force of the hair treating agent to disturb proper perming of the hair H. Thus, in order to efficiently use the hair treating agent, the photoreactive hair treatment apparatus 100 may include a humidity detector capable of detecting humidity during the perming.
In addition, protein of the hair H is resistant to acid and vulnerable to alkali. That is, the hair H may be able to remain in the healthiest and stable condition in weak acid of between pH4 to pH6. Thus, in order to prevent damage and color fade of the hair H, the photoreactive hair treatment apparatus 100 may include a pH detector for detecting pH of the hair H.
Hereinafter, operation of a photoreactive hair treatment apparatus according to a first embodiment will be described.
First, a photocatalyst may be already coated on the outer surface of the light diffusion unit 150 to form the photocatalyst coating layer 151, may be coated on the hair H which is coated with a hair treating agent, or may be coated on the hair H in the form of a mixture with a hair treating agent. As such, with the photocatalyst being provided, a user may open the light reflection unit 170 and roll the hair H around the outer surface of the light diffusion unit 150.
In the case of using the photoreactive hair treatment apparatus 100 wirely, a user may connect the power cable 139 to the connector 137 and manipulates the power switch 135 to apply power. In the case of using the photoreactive hair treatment apparatus 100 wirelessly, the user manipulates the power switch 135 to apply power.
As such, as power is applied, light is emitted from the light source 110. The light diffusion unit 150 uniformly diffuses light to emit the light toward the hair H. The photocatalyst facilitates photoreaction, thereby treating the hair H.
In this case, light having passed between the hair H is reflected by the light reflection unit 170 and then introduced back to the hair H. Thus, the light is prevented from being emitted to the outside of the photoreactive hair treatment apparatus 100, and thus, a loss of light may be prevented.
During the hair treatment, the temperature detector 191, the humidity detector 193, and the pH detector 195 detect temperature of the photoreactive hair treatment apparatus 100, humidity of the hair H, and pH of the hair H. By monitoring the temperature of the photoreactive hair treatment apparatus 100 and the humidity and pH of the hair H in real time, the user may control driving of the photoreactive hair treatment apparatus 100 according to the temperature of the photoreactive hair treatment apparatus 100 and the humidity and pH of the hair H, or may adjust concentration of the hair treating agent, humidity, and the like.
As such, the photoreactive hair treatment apparatus 100 according to the first embodiment may enhance efficiency in treating the hair H of the user as light emitted from the light source 110 is uniformly diffused, introduced to the hair H, reflected by the light reflection unit 170, and introduced back to the hair H.
Hereinafter, a photoreactive hair treatment apparatus according to another embodiment will be described.

As such, with the photocatalyst being provided, a user may manipulate the pair of handles 230 to open the pair of the heads 210. The user may place hair H between the pair of the heads 210 and manipulates the pair of the handle 230 to bring the pair of the heads 210 in contact with each other.
In the case of using the photoreactive hair treatment apparatus 100 wirely, a user may connect the power cable 139 to the connector 137 and manipulates the power switch 135 to apply power. In the case of using the photoreactive hair treatment apparatus 100 wirelessly, the user manipulates the power switch 135 to apply power.
As power is applied, light is emitted from the light source 110. The light diffusion unit 150 uniformly diffuses light to emit the light toward the hair H. The photocatalyst facilitates photoreaction, and the hair H reacts to the light, thereby treating of the hair H. In this case, light having passed between the hair H is reflected by the light reflection unit 170 and then introduced back to the hair H. Thus, the light is prevented from being emitted to the outside of the photoreactive hair treatment apparatus 200, and thus, a loss of light may be prevented.
During the hair treatment, the temperature detector 191, the humidity detector 193, and the pH detector 195 detect temperature of the photoreactive hair treatment apparatus 100, humidity of the hair H, and pH of the hair H. By monitoring the temperature of the photoreactive hair treatment apparatus 100 and the humidity and pH of the hair H in real time, the user may control driving of the photoreactive hair treatment apparatus 100 according to the temperature of the photoreactive hair treatment apparatus 100 and the humidity and pH of the hair H, or may adjust concentration of the hair treating agent, humidity, and the like.
As such, the photoreactive hair treatment apparatus 200 according to the second embodiment may enhance efficiency of treatment of the hair H as light emitted from the light source 110 is uniformly diffused, incident onto the hair H, reflected by the light reflection unit 170, and introduced back to the hair H.

The switch 135a may enable turning on/off power that is applied to the board 110a through the second connector 137b.
Meanwhile, as described above, a photocatalyst may be contained in a hair treating agent and coated directly on hair, but, even though the photocatalyst is additionally coated on the light diffusion unit 150, the photocatalyst have the same effects, and thus, an additional photocatalyst layer may be formed on the outer surface of the light diffusion unit 150.
Referring to
As such, the photoreactive hair treatment apparatus 600 according to the sixth embodiment may perform a predetermined treatment as light is emitted from the light source (not shown) and hair reacts to the light.

Light emitted from the light source 110 may be transferred to the light diffusion unit 150, and the light having passed through the light diffusion unit 150 may be radiated toward a user's hair.
As such, the photoreactive hair treatment apparatus 500a, 600a, 700a, and 800a according to the ninth embodiment does not limit the shape and output of the light source 110 since the light source is disposed outside the light diffusion unit 150, and various light sources, such as an LED, a laser diode, a laser, a halogen lamp, and the like, may be used.
In addition, since the light source 110 in the photoreactive hair treatment apparatus 500a, 600a, 700a, and 800a according to the ninth embodiment is disposed outside the light diffusion unit 150, a portable power source using a battery may be used as the power supply unit 130b and a commercial alternating power source may be used.
