The present invention relates to a hair brush, and more particularly, to a multifunctional brush for scalp care using low-temperature air, which are different from conventional hair dryers using high-temperature air.
People spend much time and effort taking care of their appearance, in particular, their face and hair. The scalp and hair act as a buffer against external shocks and help to protect the human body from ultraviolet rays and the cold. In particular, hair is an importance factor to people's appearance. Accordingly, anyone wants to have thick elastic hair.
However, physical attractiveness may not result from taking care of only hair. Another important factor for physical attractiveness is health. Accordingly, efforts are required to keep the scalp essential to hair growth healthy.
In general, people wash their scalp and hair with shampoo, dry their hair with a towel and then, use a hairdryer for drying, styling and curling hair almost every day to keep their scalp and hair clean and to make their hair look beautiful. Conventional hairdryers supply hot-temperature air directly to hair to dry and style (curl) hair. They are not used for scalp care which is helpful for hair growth.
Conventional hairdryers which dry and style (curl) hair by supplying hot-temperature air directly to hair have an advantage of speeding up the process of drying and curling hair. However, because such hairdryers supply hot-temperature air directly to hair, the scalp and hair may be excessively dry and may be damaged. Accordingly, when they are used to dry hair, they should remain at a certain distance away from hair not to damage hair. This is why conventional hairdryers are used just for drying hair but for caring the scalp.
Meanwhile, for instance, unlike conventional hairdryers described above, Korean Patent No. 10-1076057 (Korean Patent Application No. 10-2011-0076705) discloses multifunctional hair brush invented by JOONGANGBUITECH CO., LTD. in relation to a multifunctional brush for scalp care.
Korean Patent No. 10-1076057, as illustrated in
In more detail, Korean Patent No. 10-1076057 includes a comb body 10 having an accommodation space 11; a bed 20 which consists of materials with a certain level of elasticity, encloses the upper portion and has through-holes 21 formed to be regularly spaced; a UV LED lamp 30 which is placed in the accommodation space and radiates ultraviolet rays by using provide power; optical fiber bristles 40 which have a certain length for brushing hair, is installed to be regularly spaced on the bed and consists of optical fibers, whose one end is placed in the rear direction such that the light radiated by the UV LED lamp may come in and whose other side has a plurality of optical fiber bristles 40 protruding forward from the bed; a vibrator 50 for vibrating the bed by using provided power; a blowing fan 60 which is placed in the accommodation space, rotates by using provided power and blows air toward the bed so as to release air outwardly through-holes; a power supply unit 100 for supplying power to the UV LED lamp, the vibrator and the blowing fan; and an operation switch 200 which is provided at the outer side of the comb body and controls power supply of the power supply unit through the user's operation.
Unlike conventional hairdryers, the multifunctional comb according to Korean patent No. 10-1076057 described above does not use any heating element, but blows room-temperature air on hair through the through-holes such that hair is prevented from being damaged by heat while the optical fiber bristles 40 radiate ultraviolet rays emitted by the UV LED lamp 30 to help to directly deliver the radiated ultraviolet rays to the scalp. Accordingly, the ultraviolet rays radiated through the through-holes 21 are delivered to hair, and the ultraviolet rays radiated by the bristles 40 are delivered to the scalp such that the scalp and hair may be evenly sterilized. Further, the bristles 40 for combing hair play a role of delivering vibration of the bed to the scalp.
A multifunctional comb according to Korean patent No. 10-1076057 described above functions not only as a common comb but also as a comb for sterilizing, massaging or crying the scalp and hair. In particular, unlike conventional hairdryers which supply hot-temperature air to hair at a certain distance away from hair to dry hair, the multifunctional comb according to Korean patent No. 10-1076057 is effective in taking care of the scalp as well as hair by emitting room-temperature air and ultraviolet rays.
The multifunctional comb according to Korean patent No. 10-1076057 includes a blowing fan 30 as an element but does not disclose an air intake opening although the multifunctional comb needs a sizeable air intake opening to attract external air into the accommodation space 11 such that the blowing fan circulates air. In addition, if the multifunctional comb included an air intake opening, the accommodation space 11 would be an opened space due to the air intake opening. Accordingly, even if the blowing fan operates, the pressure at which air is blown does not act with the small-sized through-holes 21 of the bristles. This results in the counter-flow of air together with loud noise. Further, the multifunctional comb according to Korean patent No. 10-1076057 discloses bristles 40 consisting of optical fibers capable of delivering ultraviolet rays emitted by a UV LED lamp. However, a material used in the data communication field such as optical communication cables is not an appropriate material to manufacture hairbrush bristles requiring stiffness because optical fibers are inorganic fibers with a certain level of elasticity. Further, the multifunctional comb according to Korean patent No. 10-1076057 only lists elements such as a blowing fan, an accommodation space 11 and a vibrator 50 without disclosing how the blowing fan is installed in a relatively small accommodation space 11, and how the vibrator 50 vibrates the bed in detail and without disclosing technical features that can be proved by repetitive experiments. Accordingly it is doubtful whether the multifunctional comb is commercially available.
Further, the multifunctional comb according to Korean patent No. 10-1076057 includes optical fiber bristles 40 which have a certain length, is installed at a bed 20 and is used for combing hair and whose one end allows ultraviolet rays radiated by an LED lamp to come in. To do so, one end of the optical fiber bristles 40 should come into direct contact with the light source of an LED lamp to allow the light to come in. That is, the multifunctional comb is thought to have a configuration in which the optical fiber bristles 40, the LED lamp and the drive PCB thereof etc. are integrally fixed. When it comes to such a configuration, it is difficult to configure the optical fiber bristles 40 and it is difficult to replace the optical fiber bristles in the case that the optical fiber bristles 40 are contaminated or damaged.
Further, the multifunctional comb according to Korean patent No. 10-1076057 has no advantage similar to that of conventional hairdryers using hot-temperature air because the multifunctional comb according to Korean patent No. 10-1076057 does not include any heating element. Further, the multifunctional comb does not disclose how a low-temperature heating element would be installed in a brush-type accommodation space 11 which is relatively flat and has a small volume, and how such a heating element is located with respect to and organically related to other essential elements such as the blowing fan, the drive motor of the blowing fan, the vibrator, the LED lamp, the PCB etc., if the multifunctional comb included a low-temperature heating element to supply to the scalp air of 40° C. or so which is similar to the body temperature.
Like the multifunctional comb according to Korean patent No. 10-1076057, the present invention relates to a multifunctional brush for taking care of the scalp as well as hair. However, the present invention is different from the multifunctional comb according to Korean patent No. 10-1076057 in that the present invention is commercially available and the present invention is provide as a means to solve the above-described structural and functional problems.
