5 is a longitudinal sectional view of the active component cartridge shown in Fig.

Referring to Fig. 5, the active component cartridge 50 includes a receptor 51 and a discharge tip 53. Fig.

In the receptor 51, an accommodation space 511 is formed in which the active ingredient 55 recommended for the condition of the scalp analyzed through the image photographed by the imaging means 70 is accommodated, as described above. A fastening hole 513 is formed at one side of the receptor 51.

The discharge tip (53) includes a tip body (531).

A holder 537 is formed on one side of the tip body 531 and a discharging means 539 is provided on the holder 537. A fastening protrusion 533 to be fastened to the fastening hole 513 is formed on the other side of the tip body 531 so that the tip body 531 is fastened to the receptor 51. The active ingredient pores 535 are formed in the tip body 531 so that the active ingredient 55 can flow.

As the discharge means 539, an application ball rotatably coupled by one side of the discharge tip 53, that is, the holder 537, as shown in the figure, can be used. A part of the application ball is exposed to one side of the discharge tip 53. When the exposed part is rotated while contacting the scalp, the active ingredient 55 flowing through the effective component powdery pores 535 flows along the surface of the application ball, And can be applied.

A large number of fine protrusions or grooves can be formed on the surface of the discharging means 539 in order to enhance the coating effect of the active ingredient 55 and the scalp massage effect by the coated ball, The coating ball may be made of an elastic material in order to prevent discomfort.

Although not shown, as the discharging means 539, an elastic porous substrate may be used. That is, the applicator made of a material such as cotton or a sponge is impregnated into the active ingredient 55 flowing through the effective milk powder pores 535 and is then rubbed on the scalp so that the active ingredient 55 is applied to the scalp . This assumes that a relatively large amount of the active ingredient is applied to the scalp.

On the other hand, spraying may be used as the discharging means 539 when the active ingredient 55 to be applied to the scalp is applied, such as minoxidil, which is not shown, to be used in a limited amount. That is, when a large amount of the active ingredient 55 is to be spread over a wide area of the scalp, the active ingredient 55 is sprayed in an aerosol state when the discharge tip 53 is press-fitted, It is possible to prevent the skin 55 from being applied to the scalp.

Although not shown, when the effective component 55 is in a liquid state and a small amount remains in the accommodation space 511, the effective component 55 is discharged from the discharge means 539 ) May not be supplied. For example, when the discharge tip 53 is disposed in a horizontal state when a small amount of the effective component 55 remains, the active ingredient 55 in the accommodation space 511 can not flow into the effective powdered pore 535, The active ingredient 55 may not be applied.

6 is a vertical sectional view of the massage rod shown in Fig.

Referring to FIG. 6, the head frame 11 and the massage rod 111 may be integrally formed as described above. At this time, the head frame 11 and the massage rod 111 may be made of a good conductor or may be made of a non-conductor, and then the conductor may be plated on the surface thereof to have electrical conductivity. This will be described below with reference to FIG.

Referring again to FIG. 2, a view is shown in which the active component cartridge 50 is inserted toward the insertion hole 115. It is assumed that the effective component cartridge 50 is inserted in the direction of the massage head 10 so that the receptacle 51 of the active component cartridge 50 is inserted into the insertion hole 115 and the support substrate 41, Through the through hole 411 of the insertion hole 115 and the edge portion of the through hole 115 after being inserted into the inner space of the housing 20.

For this, a support packing or the like for increasing the frictional force is provided at the edge of the insertion hole 115 and the through hole 411 so that the inserted and fixed effective component cartridge 50 is not separated again, The active ingredient cartridge 50 can be finely flowed and resiliently supported when the means 539 is brought into contact with the scalp.

On the other hand, when the other end of the effective component cartridge 50, that is, the opposite end of the portion where the fastening hole 513 of the receptor 51 is formed is close to the cover 23, The effective component cartridge 50 may be elastically supported.

In this case, when the active component cartridge 50 is to be replaced, the cover 23 may be detached from the housing 20, and the active component cartridge 50 may be drawn out and inserted through the opening 21 .

The operation of the scalp management device 1 having the above-described configuration with reference to FIG. 4 will be described.

When the user P grasps the scalp management device 1 with the hand H and then massage the massaging rod 111 by touching the scalp S of the portion requiring management, (27). At this time, the contact electrode 27 may be formed to have a position and an area which are easy to contact with the hand H.

When the controller 30 charges the massaging rod 111 and the contact electrode 27 to have polarities different from each other, the ion component contained in the active component 55 is more easily penetrated into the scalp by the active component cartridge 50 . That is, the effect of iontophoresis can be obtained.

When the vibration generator 60 is activated when the massage bar 111 is in contact with the scalp, the generated vibration is transmitted to the scalp through the housing 20, the head frame 11 and the massage bar 111 do.

This vibration stimulates the capillaries arranged on the scalp to improve blood circulation. Therefore, when the active ingredient (55) is applied in addition to its own effect of improving the scalp, the effect of accelerating its absorption can also be obtained.

In addition, when the light emitting device 43 is operated to irradiate the scalp with light, the effect of phototherapy by the light can be obtained. The effect of the light beam will be described again with reference to Fig. 8 below.

As described above, the scalp management device 1 according to the embodiment of the present invention can diagnose the scalp condition, provide information for selection of a proper effective ingredient, efficiently induce effective absorption of the effective ingredient through ion migration, And the light of a suitable wavelength can be irradiated according to the state of the scalp, so that a very high scalp management effect can be obtained.

However, if the active ingredient 55 is unnecessary in some cases, the active ingredient cartridge 50 can be used after being drawn out from the insertion hole 115. In order to prevent excessive stimulation to the scalp during hair loss, The operation of the portion 60 may be stopped and the light emitting element 43 may irradiate only the light beam.

These various operating behaviors can be selected by inputting the signal of the switch 251 to the control unit 30 by the user's pressing and inserting the operating button 25 or the like, A dip switch that can be operated by a combination of a plurality of switches in place of the operation button 25 and the switch 251 may be utilized to facilitate selection.

Fig. 7 is a view for explaining a modified example of the massage bar shown in Fig.

Referring to FIG. 7, the head frame 12 further includes a massage tip 122. The massage tip 122 is detachably coupled to the end of the massage rod 121 and may be made of a material having electrical conductivity, elasticity and porosity.

The massaging tip 122 is used to massage the scalp using the massage rod 121 so that the portion contacting the scalp has elasticity so that excessive stimulation such as a scalp with a weak scalp or a serious disease such as an infant should be avoided And the like.

The porosity of the scalp is caused by the dandruff generated in the scalp, the keratin removed from the scalp, the sebum secreted from the scalp, and the like, so that the scalp is cleaned.

FIG. 8 is a view for explaining a modified example of the light emitting device shown in FIG.

Referring to FIG. 8, a plurality of first light emitting devices 431 and a plurality of second light emitting devices 432, which emit light beams of different wavelengths, are dispersedly disposed on the support substrate 41 of the light irradiation unit 40. It is assumed that the effect of light rays according to wavelengths is different.

For example, when oxine is used as the active ingredient (55) and light rays having a wavelength of about 410 nanometers are irradiated, phase sterilization or killing of acnes is caused and sebaceous gland activity is suppressed. A healing effect can be obtained.

Light rays with a wavelength of about 570 nm can improve symptoms caused by pigmentation such as spots or freckles, and light rays with a wavelength of about 540 nm can reduce capillaries to improve facial flushing and capillary dilation And a light ray having a wavelength of about 650 nanometers can suppress the growth of hair root to obtain a hair removal effect and a light ray having a wavelength of about 630 nanometers stimulates collagen and elastin producing cells, And the like.

Accordingly, when the control unit 30 allows the plurality of first light emitting devices 431 and the plurality of second light emitting devices 432 to operate as needed, it is possible to irradiate a light beam having a wavelength suitable for the condition of the scalp to be managed .

For this purpose, the types of light emitting devices that emit light beams of different wavelengths, such as the first light emitting device 431 and the second light emitting device 432, may be added, and the control unit 30 may be configured to blink have.

Therefore, the scalp management apparatus 1 according to the embodiment of the present invention can be used for various purposes such as treatment for various scalp diseases, alleviation of symptoms caused by aging of the scalp, prevention of hair loss, Can be utilized. In addition, it can be used for skin care for various purposes such as alleviation of various diseases caused in the skin of the body, improvement of wrinkles and elasticity in addition to the scalp.
