Referring to FIG. 4 , the light source module 300 may include a near-infrared ray generator 310, an LED device 320, and a microcurrent generator 330.

The near-infrared ray generator 310 is a device that emits near-infrared rays. Near-infrared rays refer to electric waves having the shortest wavelength in the light spectrum, and generally refer to light having a wavelength of 0.75 to 3 μm when classified according to the length of the wavelength. It is known that near-infrared rays can penetrate up to 6 mm of the subcutaneous layer, have excellent heat transfer, and can activate cells by generating ATP and nitric oxide. In addition, it is known to have a skin recovery effect by discharging waste products present deep in the skin, promoting cell regeneration, and inducing stimulation of collagen and elastin.

The near-infrared ray generator 310 may emit near-infrared rays having a wavelength of 0.75 to 3 μm. A user may control power to be applied to the near-infrared ray generator 310 by bringing the skin contact unit 200 into contact with an area requiring near-infrared beauty and manipulating the control unit 110 . Near-infrared rays emitted from the near-infrared ray generator 310 are emitted to the outside of the skin care device 10 capable of emitting far-infrared rays effective for the skin through the skin contact unit 200 to cause skin beauty effects. The above information is equally applied to the LED element 320 and the microcurrent generator 330 to be described later.

In addition, the light source module 300 may include a plurality of LED elements 320 . Each of the plurality of LED elements 320 may have different wavelength regions of emitted light. The controller 500 may control light emission of the plurality of LED elements 320 .

Specifically, the LED element 320 includes a first LED element 321 emitting light in a wavelength range of 400 nm to 460 nm, a second LED element 322 emitting light in a wavelength range of 590 nm to 660 nm, and a wavelength range of 800 nm to 900 nm. It may include a third LED element 323 that emits light in a wavelength region of .

The user can control each LED element 320 to selectively emit light or two or more LED elements 320 to simultaneously emit light according to the condition of the skin.

For example, when treatment of skin diseases such as acne and warts is required, the user manipulates the manipulation unit 110 so that the first LED element 321 emitting light in a wavelength range effective for the above-mentioned skin diseases emits light. can do. According to a signal from the control unit 110, the control unit 500 may control the light source module 300 so that only the first LED element 321 emits light. In addition, when treatment of inflammation is required, the user can control the second LED element 322 to emit light in a wavelength range effective for treatment of inflammation. In addition, when skin regeneration management is required, the user can control the third LED element 323 to emit light in a wavelength range effective for skin regeneration. The wavelength range and treatment purpose described above are exemplary, and are not limited thereto.

The first LED element 321 may emit blue light, the second LED element 322 may emit green light, and the third LED element 323 may emit red light. Therefore, the user can control the control unit 500 to check the light emission color of the LED element 320 and to make the LED element 320 suitable for the purpose of use emit light.

The microcurrent generator 330 may stimulate the skin by generating a microcurrent. The controller 500 may control the microcurrent generator 330 based on a signal applied from the manipulation unit 110 .

The microcurrent may be a minute current of less than 1000 μA (microampere) having a form similar to that of a biocurrent. Biocurrent activates components in the skin and plays an important role in maintaining healthy skin. When microcurrent is delivered to the body, it can synthesize collagen and elastin in the skin to help fundamentally solve aging problems such as skin moisture, wrinkles, and elasticity. In addition, aging concerns can be alleviated by holding the center of the skin so that the skin can remain elastic for a long time. The user controls the intensity and generation cycle of the microcurrent generated by the microcurrent generator 330 through the control unit 110. It can be controlled to generate a microcurrent suitable for the purpose of use.

The aforementioned near-infrared ray generator 310, the LED device 320, and the microcurrent generator 330 may be driven simultaneously or individually.

Meanwhile, the controller 500 may control power to be cut off from the battery 400 to the light source module 300 automatically after driving for a predetermined period of time. For example, the predetermined time may be 10 minutes, but is not limited thereto. This is to prevent damage to the skin when irradiated with light for a long time.

6 is a diagram showing an arrangement of LED elements 320 of a skin care device 10 capable of emitting far infrared rays effective for the skin according to an embodiment.

Referring to FIG. 6 , a plurality of LED elements 320 may be sequentially disposed on the skin contact unit 200 . Each of the LED elements 320 may be arranged in alignment with the LED elements 320 emitting light of the same wavelength region. For example, an assembly in which the first LED element 321 , the second LED element 322 , and the third LED element 323 are sequentially disposed is provided, and the assembly may be disposed in a longitudinal direction. If the user controls only the first LED element 321 to emit light and uses the skin care device 10 capable of emitting far-infrared rays effective for the skin, the first LED elements 321 aligned in the longitudinal direction are applied to the skin. Since light in a specific wavelength region is emitted through the contact unit 200, the user can contact the skin contact unit 200 to a specific area of the skin to provide intensive care.

However, the amount of radon emission is extremely insignificant, suggesting a skin care device 10 capable of emitting far-infrared rays effective for skin more effective for skin care. Since the skin contact unit 200 directly contacts the user's skin, hygienic management and maximization of skin beauty effects by far-infrared rays can be obtained.

The composition of the ceramic raw material may include water, silicon oxide (SILCA), sodium oxide (NA ₂ O ₃ ), aluminum oxide (AL ₂ O ₃ ), potassium oxide (K ₂ O) and calcium oxide (CAO), In addition, it may contain less than about 2% by weight of other materials that do not affect the antibacterial effect and the far-infrared ray emission effect.

More specifically, the ceramic raw material is 80% by weight of water, 11 to 14% of silicon oxide (SILCA), 2 to 5% of sodium oxide (NA ₂ O ₃ ), and 0 to less than 1% of aluminum oxide (AL ₂ O ₃ ) , 0 to 0.1% of potassium oxide (K ₂ O) and 0 to 0.1% of calcium oxide (CAO).

It was confirmed as follows.

① Test method

Prepare three test pieces of 50 ± 2 mm (thickness within 10 mm), use a stomacher film (50 ± 2 mm) for the control piece, and lightly wipe the bottom of the test piece two or three times with ethanol-absorbed gauze or cotton wool. After that, dry it thoroughly and test it. The inoculum is prepared by using sterilized water containing 1/500 Nutrient broth of 1 platinum of the cultured test bacteria so that the number of bacteria is 2.5 ~ 10 × 10 ⁵ CFU/mL. Put each test piece in a petri dish with the test side up, collect 0.2 mL of the test bacterial solution with a pipette, and inoculate it on each test piece. Cover the film on the dropped test strain, press lightly so that the test strain spreads over the entire film, and then cover the petri dish. The test surface should be the surface of the product that has been subjected to antibacterial processing. The initial bacterial count is 1.0 to 4.0×10 ⁵ CFU/ml per test piece, and the size of the film is 40 ± 2 mm. Incubate the test specimen inoculated with the test bacterial solution and the petri dish containing the control specimen at (37 ± 1) ℃ for 24 hours.

For the unprocessed test piece immediately after inoculation of the test bacterial solution, separate the coating film and test piece using sterilized tweezers, and add 10 mL of SCDLP medium to wash the test bacteria. This rinsed liquid is used for rapid viable cell count measurement. For the specimen after incubation, the test bacteria are washed in the same way, and the washing solution is quickly used for viable cell count measurement. Take 1 mL of the wash solution immediately after inoculation and culture as described above with a pipette, add it to a test tube containing 9 mL of physiological saline, and mix thoroughly. In this process, the washing solution is diluted in stages, 0.1 mL is spread on 3 plates on Nutrient agar, and incubated at (37 ± 1) ° C for 24 hours.

② Test results

Calculate the reduction rate of bacteria by the test sample as follows.

Reduction rate (%) = [(A - B) / A] × 100

Here, A refers to the number of bacteria (average value) in the control sample after incubation for 24 hours, and B refers to the number of bacteria (average value) in the test sample after incubation for 24 hours. If the number of bacteria is "0", it is indicated as "<10". If the number of bacteria in the test sample (B) is greater than the number of bacteria in the control sample (B), mark "-".

The results are shown in the table below.

Antibacterial test for Escherichia coli division initial concentration
(CFU/mL) Concentration after 24 hours
(CFU/mL) Germ
Decrease rate (%) Antibacterial test:
Escherichia coli control sample 3.4 ×10 ⁵ 9.5 × 10 ⁶ - test sample 3.4 ×10 ⁵ < 10 99.9

Antibacterial test for Pseudomonas aeruginosa division initial concentration

(CFU/mL) Concentration after 24 hours
(CFU/mL) Germ
Decrease rate (%) Antibacterial test:
Staphylococcus aureus control sample 1.4 × 10 ⁵ 4.0 × 10 ⁶ - test sample 1.4 × 10 ⁵ < 10 99.9

As a result of the test, the number of remaining Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus in the control group increased and did not have antibacterial activity. This appearance could be confirmed. Referring to Figures 7b to 7d, it can be clearly confirmed with the naked eye that it has an antibacterial effect against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus, respectively.

On the other hand, in the case of out of the above-described composition range, it did not have the antibacterial effect shown in Tables 1 to 3 above.

In the present invention, a test report showing the experimental results for the far-infrared emissivity / radiant energy shown in FIG.

Referring to FIG. 8, when the above-described composition is measured at 37° C. based on KFIA-FI-1005, 88.7% of far-infrared rays having a wavelength of 5 to 20 μm are emitted, and 3.42×10 ² (W/m ² μm, 37 ℃) was confirmed to have far-infrared radiant energy. On the other hand, when the composition was out of the above-described range, the far-infrared ray emission effect as shown in FIG. 8 was not obtained.

Figure 9 is a measurement test result table for the radon emission rate of the skin beauty device 10 capable of emitting far-infrared rays effective for the skin according to the embodiments.

Radon (Rn) is a radioactive element that is a decay product of radium (Ra) that exists in nature, and is a colorless, odorless, and tasteless gas. The density in the standard state (STP: 0℃, 1 atm) is 9.73 g/L, which is about 8 times greater than the density of air (1.217 g/L).

Radon is an inert gas that does not react chemically with other substances, but has the property of emitting radiation. The International Agency for Research on Cancer (IARC) under the World Health Organization defines radon as a first-class carcinogen. It has been reported to account for 3% to 14% of cases.

Since there is a concern about radon generation in the case of a material that emits far-infrared rays, even in the case of a composition composed of the same composition as the skin contacting part of a skin care device capable of emitting far-infrared rays effective for the skin according to embodiments of the present invention, concerns about radon emission are eliminated. In order to solve it, the following tests were conducted.

It is not easy to measure the radon emission rate (pCi/m2.h, Bq/m2.h) for products with low radon emission, so it has to be performed by a specialized institution. In the present invention, the registered patent 10-0717953 (radon emission rate A method and device for measuring ) was commissioned by RNtech Co., Ltd., which has the license for the technology. The measurement result table is shown in FIG. 9 .

Referring to Figure 9, it can be seen that the radon emission rate of the composition made of the above-described composition is extremely insignificant as 0.554 pCi/m ² ·hr (0.021 Bq/m ² ·hr).

Therefore, the skin contact unit 200 made of the above-described composition has the advantage of securing stability because the amount of radon harmful to the human body is equal to or less than that of general materials while emitting far-infrared rays.

Since the light emitted from the light source module 300 is irradiated through the skin contact unit 200, the user contacts the skin contact unit 200 to the beauty area. At this time, the cosmetic effect can be further maximized by the antibacterial effect and the far-infrared ray emission effect of the skin contact unit 200, and it can have an effect of easy management and storage. In addition, stability can be secured because it is extremely minimal at a level without radon emission.

10 is a diagram showing a skin contact unit 200 of a skin beauty device 10 capable of emitting far infrared rays effective for the skin according to an embodiment.

Referring to FIG. 10 , the skin contact unit 200 may include a first portion 210 that is a predetermined area in the center and a second portion 220 that is the remaining portion except for the first portion 210 . The first area may be in direct contact with the skin and may have a higher risk of contamination than the second portion 220 and may have a greater effect on the skin. Therefore, in order to effectively manage the skin care device 10 capable of emitting far-infrared rays effective for the skin and maximize skin care effects, the content of the ceramic raw material in the first part 210 is greater than the content of the ceramic raw material in the second part 220. There could be more. For example, the content of the ceramic raw material in the first part 210 may be 8 to 10% by weight, and the content of the ceramic raw material in the second part 220 may be 5 to 8% by weight. Manufacturing costs can be reduced by varying the content of the ceramic raw material according to the area of the skin contact unit 200 .

As described above, the preferred embodiments according to the present invention have been reviewed, and the fact that the present invention can be embodied in other specific forms without departing from the spirit or scope of the present invention in addition to the above-described embodiments is known to those skilled in the art. It is self-evident to them. Therefore, the embodiments described above are to be regarded as illustrative rather than restrictive, and thus the present invention is not limited to the above description, but may vary within the scope of the appended claims and their equivalents.
