Description

  The present invention relates to a brush for combing hair, and more particularly to a multi-function brush capable of caring for the scalp by low-temperature air blowing, and is distinguished from a normal high-temperature hot air supply type hair dryer.

  People want to dress their appearance beautifully, and spend a lot of time and money, especially to make their face and head beautiful. Human scalp and hair are important for cosmetic aspects such as absorption of external impacts, protection from ultraviolet rays, and insulation from cold, as well as functional aspects that determine the appearance of the human body, and everyone is fluffy and full of elasticity. I want.

  However, hair that is an element that determines the attractive appearance cannot be obtained simply by managing the hair alone, but it must manage the scalp that grows the hair with the effort to keep the whole body healthy. .

In general, people shampoo and wash their scalp and hair almost daily for scalp and hair cleanliness and beauty, then use a towel to drain the hair to some extent and then dry and hair styling enough or Dry the hair using an electric hair dryer to achieve hair curling. Most conventional hair dryers have not been scalp care tools for the scalp that grows hair by simply applying high temperature hot air directly to the hair for drying and styling (curling) of the hair during its use.

  Conventional hair dryers that apply high-temperature hot air directly to the hair for drying and styling (curling) of the hair can achieve the quickest hair drying effect and styling effect by applying high-temperature hot air directly to the hair. However, in order to avoid excessive damage, the hair dryer and the scalp are prone to overdrying because it applies high heat directly to the hair. You have to guess. Therefore, the conventional hair dryer is a drier for hair and is never a scalp care tool, as is apparent from the general usage situation.

  On the other hand, in the technology developed as a multi-functional brush for scalp care instead of the conventional hair dryer as described above, for example, a patent application (Korea patent application) was filed by Chuo Butech Co., Ltd. (Title of multi-functional brush) No. 10-2011-0076705) There is a technique of registered patent No. 10-1076057.

  This Korean Patent No. 10-1076057 is a UV LED lamp 30 in which an optical fiber brush 40 made of an optical fiber is mounted on a mother board 20 with through holes 21 formed at predetermined intervals as shown in FIG. The light of the ultraviolet wavelength output in step 1 is irradiated to the scalp and hair through the optical fiber brush 40 and the through-hole 21 formed in the mother plate 20, so that the scalp and hair have a sterilizing function, and the mother plate is vibrated. A vibrator 50 is provided to perform a scalp massage function through an optical fiber brush that is vibrated together with the mother board 20, and a blower fan 60 is provided to allow air to flow out through a through hole formed in the mother board. The present invention relates to a multifunctional brush having a function of drying wet hair.

  More specifically, the configuration of the multifunctional brush according to the above-mentioned Korean Patent No. 10-1076057 will be described. The multifunctional brush is composed of a comb body 10 in which an accommodation space 11 is formed, and a material having a predetermined elasticity. The mother board 20 is formed by sealing the upper part of the accommodation space, and through holes 21 are formed at a predetermined interval, and the ultraviolet LED lamp 30 is disposed in the accommodation space and is supplied with power to output light having an ultraviolet wavelength. And have a predetermined length so that the hair can be combed, are attached to the mother board at predetermined intervals, and are made of an optical fiber so that light output from the ultraviolet LED lamp is incident on one end thereof. The other end is disposed behind the mother board and the other end protrudes forward of the mother board, a vibrator 50 that receives power and vibrates the mother board, and is disposed in the accommodation space to receive power. Rotated A blower fan 60 that blows wind in a direction in which the mother board is directed so that the wind flows out through the through hole, an ultraviolet LED lamp, a vibrator, a power supply unit 100 that supplies power to the blower fan, and a comb body And an operation switch 200 that controls the power supply of the power supply unit by a user's operation.

  The multifunctional brush according to the Korean Patent No. 10-1076057 prevents heat damage to the hair by applying normal temperature wind to the hair through a through hole without using any heat generating element unlike a hair dryer commonly used in the past. On the other hand, by irradiating ultraviolet rays emitted from the ultraviolet LED lamp 30 to the optical fiber brush 40, the ultraviolet rays can be directly transmitted to the scalp without clogging the hair, thereby being irradiated through the through holes 21. The ultraviolet rays applied to the hair and the ultraviolet rays irradiated through the brush 40 are applied to the scalp so that the hair and the scalp are evenly sterilized, while the brush 40 that combs the hair transmits the vibration of the mother board to the scalp. This technology is in charge of the function of the vibration transmitter.

  The technique of the multifunctional brush according to this Korean domestic patent No. 10-1076057 is a multifunctional brush that can be selected and used as a sterilization, massage or drying comb in addition to the function of a general comb, and particularly for hair. In contrast to ordinary hot air drying hair dryers, which dry hair by applying hot air at a predetermined distance, we pursue a multifunctional brush for scalp care that cares for the hair and scalp together by normal temperature air and ultraviolet irradiation. Therefore, it is technically different from conventional high-temperature hot-air drying hair dryers.

  However, in the multi-function brush technology according to Korean Patent No. 10-1076057, a component called the blower fan 30 is conceptually presented. However, there is no proposal or explanation for such an air intake, and a predetermined air intake is required. When the opening is provided, the accommodation space 11 becomes an open space that is not a sealed space due to the presence of the air suction port, so that even if the blower fan is driven, a small through hole 21 between the brushes on the mother board 20 is provided. As a result, the air flow is reversed with the generation of complex noise through the air inlet when the blower fan is driven. Problems that put away is expected. Also, in the multifunctional brush technology according to Korean Patent No. 10-1076057, it is described that the brush 40 is made of an optical fiber that transmits ultraviolet rays emitted from the LED lamp. It is a flexible inorganic fiber as a material used in the information communication field such as an optical communication cable, and such a flexible optical fiber is used as a brush that requires a considerable stiffness to comb the hair. The claim is difficult to convince. In the multi-function brush technology according to Korean Patent No. 10-1076057, the vibrator and vibrator that vibrates the mother board, the configuration and structure of the blower fan installed in the relatively narrow housing space 11 50 does not present any specific and reproducible technical contents on what configuration can be used to vibrate the mother board, and is merely an enumeration of such elements, and its practical application Must be a desktop invention that is highly questioned.

  In addition, with the multifunctional brush technology according to Korean Patent No. 10-1076057, the optical fiber brush 40 attached to the mother board 20 with a predetermined length for combing hair is output from one end of the LED lamp with an LED lamp. In order to achieve this, one end of the optical fiber brush 40 must be in direct contact with the LED lamp as a light source, that is, the light must be incident, that is, the optical fiber brush 40 and the LED lamp. The fixing structure is physically integrated with the driving PCB and the like. However, with such a fixing structure, not only the configuration of the optical fiber brush 40 is difficult, but also the replacement is difficult when the optical fiber brush 40 is contaminated or broken. is there.

  In addition, since the multi-functional brush technology according to Korean Patent No. 10-1076057 does not adopt any heating element, the advantages of the conventional hot air drying hair dryer cannot be enjoyed at all. In the case where an additional predetermined low-temperature heating element is further added to supply a scalp with body temperature air of, for example, about 40 ° C., the heating element is arranged in a relatively narrow and bulky flat brush type accommodation space 11 in any configuration. How can it be mounted, and what inter-organic positional relationship and organic coupling relationship with other essential components like blower fan, blower fan drive motor, vibrator, LED lamp, PCB board etc. There is no disclosure about what can be included.

  The present invention provides a multi-function brush for scalp care that can perform a multi-function care function not only for hair, but particularly for the scalp, as in the multi-function brush technique according to Korean Patent No. 10-1076057. However, unlike the comb according to Korean National Patent No. 10-1076057, it can be practically used, and can realize many scalp care products in which all the structural and functional problems as described above are solved. Provide functional brushes.

There is an advantage that it does not cause a large blowing resistance. This is equivalent to the LED lamp and its PCB board 110 being placed at the position of the typhoon eye.

  FIG. 7 is a plan view, an elevation view, a perspective view, and a weeding sickle structure perspective view showing a blower fan 70 used in a multifunctional brush for scalp care according to the present invention. FIG. It is a ventilation speed comparison drawing which compared the ventilation fan c used for the multifunctional brush for scalp care by the case of the conventional general ventilation fan (a) (b).

It is lower than the height h2 of 76 (h1 <h2). The triple-wing configuration (fan blade + auxiliary projection blade + tip wing) of the blower according to the present invention improves the straightness and speed of air delivery even with a small amount of power.

  That is, as can be seen from FIG. 8, the blower fan c used in the multifunctional brush for scalp care according to the present invention can be seen by comparing the amount of blown air (blowing speed) as compared with the conventional blower fans a and b. For example, as a result of measuring the blowing speed of the conventional blower fan of the present invention and the blower fan according to the present invention using the same low power, the conventional blower fan is 2.7 m / sec, 4.2 m. On the other hand, in the case of the blower fan according to the present invention, the blower speed is 6.7 m / sec, which is about 1.5 to 2.5 times higher than the conventional blower efficiency. Showed. Such a result is the basis for making it possible to use a low-power lithium ion secondary battery, and can be designed to consume less driving power of the blower fan 40.
