1 to 5, a skin beauty device 10 according to an embodiment of the present invention includes a body 100 that can be gripped by a user, a measurement unit 200 that can measure a user's skin condition, A display unit 300 capable of indicating the skin condition of the user measured by the measurement unit 200 and an operation unit 400 capable of applying at least one of light and microcurrent to the user's skin may be included. However, what can be applied by the skin beauty device 10 according to an embodiment of the present invention is not limited to light and microcurrent, and the skin beauty device 10 can apply vibration or ultrasound.

The body 100 forms the appearance of the skin beauty device 10, and components constituting the skin beauty device 10 may be accommodated in the body 100 or mounted on the body 100.

The main body 100 is located on the opposite side of the upper surface 110 on which the measuring unit 200 is located and the side 120 and the upper surface 110 that can be gripped when the user is using it It may include a bottom surface 130.

A measuring unit 200 capable of measuring the user's skin condition and an operation unit 400 capable of applying one or more of light and microcurrent to the user's skin may be positioned on the upper surface 110. A display unit 300 capable of indicating a user's skin condition and a button unit 500 for operating the operation unit 400 may be positioned at 120.

The upper surface 110 may be formed as an inclined surface inclined at a predetermined angle with respect to the horizontal plane (XY plane). For example, as shown in FIG. 3, the upper surface 110 may be an inclined surface in which one side has a relatively higher height than the other side with respect to the bottom surface 130 of the main body 100, and the measurement unit 200 and The operation unit 400 may be located on the same plane as the upper surface 110. By including the upper surface 110 inclined at a predetermined angle, the user can move the skin beauty device 10 while in contact with the user's face in a more comfortable posture.

A battery (not shown) for applying power 620 to the skin beauty device 10 may be mounted inside the body 100 on the upper side of the bottom surface 130.

The measurement unit 200 is a component capable of measuring a user's skin condition. For example, the measurement unit 200 may include an oil and moisture sensor for measuring the degree of oil and moisture and an elasticity sensor for measuring the degree of elasticity. The oil and moisture sensor may include a first electrode 210 oscillating at a preset frequency and a second electrode 220 receiving a frequency oscillated from the first electrode 210. In this case, the first electrode 210 and the second electrode 220 may be disposed side by side, and an insulator may be disposed between the first electrode 210 and the second electrode 220 to prevent current from flowing.

When using the first electrode 210 and the second electrode 220 as described above, the amount of moisture and the amount of oil may be accurately measured. In addition, since the measurement unit 200 can be miniaturized, even if the measurement unit 200 touches the skin, a sense of heterogeneity accordingly can be reduced.

The measurement unit 200 may calculate the amount of oil and water in the skin according to a difference between the frequency value oscillated from the first electrode 210 and the frequency value received from the second electrode 220.

The frequency oscillated from the first electrode 210 cannot be directly transmitted to the second electrode 220 and may be transmitted to the second electrode 220 only through the skin of the user with which the measurement unit 200 is in contact. . However, the dielectric constant of the skin varies according to the amount of oil and water in the user's skin, and the frequency attenuation amount varies according to the dielectric constant of the user's skin when the frequency passes through the user's skin. That is, the frequency measured by the second electrode 220 varies depending on the amount of oil and water in the user's skin.

The measurement unit 200 may calculate the amount of oil and water of the skin according to the amount of change in frequency, and matching data of the amount of oil and water for a specific frequency and the amount of frequency change for this purpose may be stored in the memory 610.

In addition, the frequency oscillated from the first electrode 210 may be varied by the control unit 600. That is, the control unit 600 can change the frequency that is oscillated from the first electrode 210 according to the manufacturer's setting or the user's setting, and for this purpose, the skin care device 10 is a control unit that allows the user to select a frequency (not shown). City) may be further provided. Here, the frequency may be 3 kHz.

In the above-described embodiment, a frequency oscillation at the first electrode 210 and reception of a frequency oscillation at the second electrode 220 have been described as an example, but the frequency is oscillated at the second electrode 220 and the first electrode The frequency oscillated at 210 may be received.

In the above-described embodiment, the measurement unit 200 has been described as an oil and moisture sensor that measures the amount of oil and water, but the measurement unit 200 is not limited thereto. For example, the measurement unit 200 may further include an elasticity sensor (not shown) that measures the elasticity of the skin.

The elasticity sensor is a pressure sensor equipped with a strain gauge, which is a kind of pressure sensor, or a probe that pressurizes by contacting the skin with one end, an elastic member connected to the other end of the probe to contact the FSR sensor, and the elastic member It may include an FSR sensor that measures the elasticity of the skin by being connected to and measuring pressure.

The measurement unit 200 may be located on the same plane as the operation unit 400. As a result, the skin condition can be simultaneously measured by the measuring unit 200 while irradiating light and passing a minute current to the skin through the operation unit 400.

The first electrode 210 and the second electrode 220 may be positioned on the upper surface 110 of the body 100 and may be disposed parallel to each other. Further, the first electrode 210 and the second electrode 220 do not contact each other, and may be arranged along the edge of the upper surface 110 together with the electrode part 420.

The first electrode 210 and the second electrode 220 may be positioned at a high portion on the inclined upper surface 110. By being arranged in this way, the user can contact the high portion of the upper surface 110 with the skin, so that the skin condition can be easily measured.

The display unit 300 may display the user's skin condition measured by the measurement unit 200 and a plurality of recommended modes to be described later. The display unit 300 may be a plurality of LEDs capable of displaying a plurality of colors. Specifically, one LED may represent a plurality of colors, and a plurality of LEDs representing a plurality of colors are provided, so that various signals and various information corresponding thereto may be transmitted to the user through the display unit 300. However, as long as the condition of the skin and a plurality of recommended modes to be described later can be displayed, the means is not limited, and a known display means using a display may be used.

In the present exemplary embodiment, the display unit 300 is described as an example of a plurality of LEDs capable of displaying a plurality of colors.

The display unit 300 may be disposed on the side surface 120 of the main body 100. However, the position where the display unit 300 is disposed on the main body 100 is not limited if the user can see it with the naked eye.

The display unit 300 may display various colors, and the skin condition of the user measured by the first electrode 210 and the second electrode 220 may be displayed according to the number of lights, color, and blinking of the display unit 300. Here, the number of lights of the display unit 300 means the number that can be recognized by the naked eye of the user.

For example, a first color of the display unit 300 may indicate an amount of moisture in the skin, a second color may indicate an amount of oil in the skin, and a third color may indicate an elasticity of the skin. Here, the first color may be blue, the second color may be yellow, and the third color may be red.

That is, the first color displayed when skin moisture is insufficient may match the color of the wavelength band (blue color) that is effective in improving the moisture level of the skin, and the second color displayed when the skin oil is insufficient The color of the wavelength band (yellow) that is effective in improving the oiliness of the skin can be matched, and the third color displayed when the skin is insufficiently elastic is the color of the wavelength band (red) that is effective in improving the elasticity of the skin. Can be matched with As a result, the user can intuitively grasp which skin improvement functions are relatively insufficient in their skin condition (moisture, oil, elasticity) and the recommended mode to be managed.

In addition, the amount of light on the display unit 300 may quantitatively indicate an amount of moisture, an amount of oil, and an elasticity. In addition, blinking of the display unit 300 (repetitively lit and turned off) may indicate a lack of moisture, oil, and elasticity.

After measuring the skin condition of the user using the skin beauty device 10, when the skin condition is insufficient in moisture, one display unit 301 may blink and display a blue color. In this case, the number of lights of the display unit 300 may indicate a lack of moisture content. For example, if there are 4 lights on the display unit 300, it is very good, if there are 3 lights, it is good, if there are 2 lights, it may indicate dry, and if the light is 1, bad drying may be indicated.

In addition, when the skin condition is insufficient in the amount of oil, the display unit 300 may blink and display a yellow color.

In addition, when the skin condition is insufficient elasticity, the display unit 300 may blink and display a red color. In addition, when the skin condition is insufficient due to the same deviation in both oil and moisture, the display unit 300 may flicker and display a red color.

Here, the blue color blink indicating lack of moisture may appear when the moisture measurement value is less than the preset person's average moisture value, and the yellow color blink indicating the lack of oil is the average oil content of the person with the preset oil measurement value. It may appear if it is smaller than the value, and the red flicker may indicate insufficient skin elasticity, the moisture measurement value and the oil content measurement value are greater than the average moisture value and the oil content value of a preset person, or the deviation between the two measurement values is the same. Or it can appear when it is 0. In this case, the degree of lack of moisture, the degree of lack of oil, and the degree of lack of elasticity may be determined as a difference between a predetermined average value.

In addition, when the moisture measurement value is less than the average moisture value of a preset person and the oil content measurement value is less than the average oil content value of the preset person, the color displayed according to the degree of difference from the average value (recommended mode color) will be selected. I can. For example, if the measured moisture value is 30, the average moisture value of a preset person is 40, the measured oil value is 18, and the average oil content value of the preset person is 20, it is determined that the moisture content is less than the oil content, Blue flashes may appear indicating lack.

That is, when one display unit 301 can display a plurality of colors, the color with the largest deviation compared to the preset average value is displayed, and if all the deviations are the same, the display priority is blue or yellow. It can be set to color or red. However, it is not limited to this order, and may be set in an order combination other than the described order.

However, in the display unit 300 according to an exemplary embodiment of the present invention, one display unit 301 may display only one color, and in this case, skin conditions such as moisture content, oil content, and elasticity are each displayed by a plurality of display units (rows). May be displayed. For example, the display unit 300 may be configured in three columns, the amount of skin moisture is displayed in the first column, the amount of oil is displayed in the second column, and the degree of elasticity may be displayed in the third column.

The display unit 300 may indicate a skin condition according to the amount of skin oil and moisture measured by the first electrode 210 and the second electrode 220, and the wavelength of light applied by the operation unit 400 based on the amount of oil and water It may represent a plurality of recommended modes for recommending the intensity of the band and the minute current.

Here, the plurality of recommended modes are a first recommended mode that recommends a first wavelength band of light applied from the operation unit 400 and a first intensity of a minute current, and a second wavelength of light applied from the operation unit 400 A second recommendation mode for recommending the second intensity of the band and the minute current, and a third recommendation mode for recommending the third wavelength band of the light applied by the operation unit 400 and the third intensity of the minute current.

Specifically, the first recommendation mode can be used as a recommendation function to replenish moisture when the measured skin moisture level is insufficient, and the second recommendation mode is used as a recommendation function to supplement oil when the measured skin oil content is insufficient. The third recommendation mode may be used as a recommendation function for improving elasticity when the elasticity of the skin is insufficient, or when the amount of moisture and the amount of oil of the skin is sufficient, and the deviation between the amount of oil and the amount of oil is equal or zero.

The operation unit 400 may apply one or more of light and microcurrent to the user's skin. In the embodiment of the present invention, the operation unit 400 is described by taking a light source 410 capable of irradiating light and an electrode unit 420 capable of applying a minute current, but the operation unit 400 applies vibration. It may include a vibration unit (not shown) for applying an ultrasonic wave unit (not shown).

The operation unit 400 may include a light source 410 capable of irradiating light of different wavelength bands, and an electrode unit 420 capable of changing an electrical environment of the skin by generating a potential difference in the user's skin. In addition, the operation unit 400 may include a translucent cover 430 disposed on the front side of the light source 410.

The light source 410 generates light having a predetermined wavelength band and irradiates it to the user's skin, and skin improvement effect according to the wavelength penetrated into the skin by the light source 410 (increased moisture content, improved skin uniformity and transparency, Elasticity improvement, etc.).

The light source 410 is disposed inside the main body 100 and may be covered by the translucent cover 430, and light emitted from the light source 410 may pass through the translucent cover 430 and be transmitted to the skin. Here, the light source 410 may include a plurality of light emitting devices that irradiate light of different wavelength bands.

For example, the light source 410 may be implemented in the form of a single chip by mounting a plurality of LED-shaped light emitting devices that irradiate light of different wavelength bands on one substrate.

The light source 410 may irradiate light of different wavelength bands. For example, the light source may irradiate a first wavelength band, a second wavelength band, and a third wavelength band of light, the first wavelength band is 400 to 480 nm, the second wavelength band is 550 to 610 nm, and the third The wavelength band may be 610 ~ 650nm. In this case, light transmitted to the skin by the first wavelength band may exhibit a blue color, light transmitted to the skin by the second wavelength band may exhibit a yellow color, and transmitted to the skin by the third wavelength band. The light that becomes can exhibit a red color.

In this way, by irradiating at least one of the first wavelength band to the third wavelength band to the skin, skin soothing effect, skin texture improvement, soothing care for sensitive skin, skin contour improvement, skin elasticity improvement, skin elasticity restoration, skin lifting improvement And it is possible to obtain effects such as improving skin gloss through one device. In general, it is known that moisture in the first wavelength band, oil in the second wavelength band, and elasticity in the third wavelength band are most effectively improved, but each wavelength band does not have only one effect, and the above-described skin improvement effects are combined. I have it. Therefore, for the cosmetic effect of the skin, it may be effective to firstly compensate for the insufficient part but irradiate light in various wavelength bands.

However, the wavelength band that can be irradiated by the light source 410 of the present invention is not limited thereto, and a wavelength band suitable for a desired skin improvement effect may be selected.

In addition, the light source 410 may be continuously lit, and may be repeatedly lit and turned off. Meanwhile, the selection of the wavelength band of the light source 410 may be performed by the button unit 500 to be described later.

The electrode unit 420 may generate a potential difference in the user's skin to provide a microcurrent capable of changing the electrical environment of the skin. The electrode unit 420 may include a pair of separated contact electrodes 420a and 420b disposed on the same plane so as to form a closed circuit with the skin when contacting the user's skin to generate a potential difference in the user's skin. . The pair of contact electrodes 420a and 420b may increase skin permeation of ionic drugs by changing the electrical environment of the skin by generating a potential difference in the user's skin when the power source 620 is applied. Specifically, the pair of contact electrodes 420a and 420b is for implementing the function of iontophoresis, and a direct current is applied to the user's body using the power 620 supplied through a battery (not shown). When applied, the user's skin and the pair of contact electrodes 420a and 420b form a closed circuit, so that the movement of ions occurs. Accordingly, when the cosmetic product applied to the skin is ionized, the effect of introducing ions into the skin tissue through the cosmetic product easily passing through the skin mucous membrane may occur.

The pair of contact electrodes 420a and 420b may be spaced apart on the same surface of the upper surface 110 as described above. In addition, the pair of contact electrodes 420a and 420b may be implemented in a bi-polar manner in which each of the contact electrodes 420a and 420b is fixed in a state spaced apart from each other on the upper surface 110.

When the user touches the upper surface 110 on the skin while applying cosmetics to the body part to be treated, a pair of contact electrodes 420a and 420b spaced apart on the same surface may be in contact with the skin at the same time. have. For this reason, even if the user changes the gripping position of the main body 100 during the use process, the iontophoresis function may be implemented so that the pair of contact electrodes 420a and 420b always keeps in contact with the skin.

The pair of contact electrodes 420a and 420b may be formed of a plate-shaped member having a predetermined area so as to increase a contact area with the skin. For example, a pair of contact electrodes 420a and 420b is formed along the edge of the upper surface 110, and the light source 410 is formed at the center of the pair of contact electrodes 420a and 420b. Can be provided. In addition, a corner formed by an edge of the pair of contact electrodes 420a and 420b may be formed in a curved surface. As a result, it is possible to prevent the user's skin from being damaged by a sharp edge while the pair of contact electrodes 420a and 420b is in contact with the user's skin and rubs the user's skin.

In addition, the pair of contact electrodes 420a and 420b may protrude from the upper surface 110 by a predetermined distance. For this reason, when the skin beauty device 10 contacts the skin, light emitted from the light source 410 may be blocked by the pair of contact electrodes 420a and 420b.

Meanwhile, the intensity of the minute current generated by the pair of contact electrodes 420a and 420b may have a plurality of intensities. In the present exemplary embodiment, the intensity of the minute current generated by the pair of contact electrodes 420a and 420b will be described as an example representing the intensity of three intensity (first intensity, second intensity, and third intensity).

The first intensity generated by the pair of contact electrodes 420a and 420b may be set to occur simultaneously when light in the first wavelength band generated from the light source 410 is irradiated. The second intensity may be set to occur simultaneously when light in the second wavelength band generated from the light source 410 is irradiated. The third intensity may be set to occur simultaneously when light of the third wavelength band generated from the light source 410 is irradiated. Here, the intensity of the minute current may increase in the order of the first intensity, the second intensity, and the third intensity.

In this way, when light in the first wavelength band and a weak microcurrent are transmitted to the skin, and the skin beauty device 10 is rubbed on the skin to which the cosmetic is applied, the improvement of the moisture content of the skin may be promoted.

In addition, light in the second wavelength band and a microcurrent of a medium intensity are transmitted to the skin, and when the skin beauty device 10 is rubbed on the skin to which the cosmetic is applied, the amount of oil on the skin is improved and the gloss can flow.

In addition, when light in the third wavelength band and a fine current of strong intensity are transmitted to the skin, and the skin beauty device 10 is rubbed on the skin to which the cosmetic is applied, the elasticity of the skin may be improved.

As described above, so that the wavelength of light emitted from the light source 410 and the minute current emitted from the electrode unit 420 are controlled, the operation unit 400 may operate in a plurality of operation modes. For example, the operation mode of the operation unit 400 is a first operation mode in which a first wavelength band of light and a first intensity of a minute current are applied, and a second wavelength band of light and a second intensity of the minute current are applied. The second operation mode, the second operation mode for applying the second wavelength band of light and the third intensity of the microcurrent, the first operation mode, the second operation mode, and the third operation mode are all operated for a preset time. Can have 4 operating modes.

These, four operation modes may be selected by the button unit 500.

The button unit 500 is an operation button 510 for selecting one of the first to fourth operation modes described above, and a plurality of colors to indicate whether the first to fourth operation modes are selected. It may include a notification unit 520.

When the operation button 510 is clicked, the first operation mode is sequentially transferred to the fourth operation mode, and such an indication may be displayed by the notification unit 520.

For example, the notification unit 520 may indicate a blue color indicating a first operation mode, a yellow color indicating a second operation mode, a red color indicating a third operation mode, and a gray color indicating a fourth operation mode. One of the first operation mode to the fourth operation mode may be selected by the operation of the button 510.

In addition, in the above-described embodiment, four operation modes (first operation mode to fourth operation mode) have been described, but the skin beauty device 10 may have sixth operation mode to eighth operation mode. For example, the operation mode of the operation unit 400 is a fifth operation mode in which only a first wavelength band of light is applied without application of a minute current, and a sixth operation mode in which only a second wavelength band of light is applied without application of a minute current. , A seventh operation mode in which only a third wavelength band of light is applied without application of a minute current and an eighth operation mode in which only a minute current is applied without application of light. In this case, one of the first to eighth operation modes may be selected by the button unit 500.

The color of the notification unit 520 is controlled by the control unit 600 to be the same color as the color displayed on the display unit 300, or by operating the operation button 510, the operation unit 400 is recommended by the display unit 300 The wavelength band and microcurrent can be applied to the skin.

In addition, the operation button 510 may be used to turn on/off the power of the skin beauty device 10. For example, when the power of the skin beauty device 10 is turned off, pressing the operation button 510 for 5 seconds or more may turn on the skin beauty device 10, and when the power of the skin beauty device 10 is turned on, If the operation button 510 is pressed for 5 seconds or more, the skin beauty device 10 may be turned off.

In addition, the skin care device 10 may include a contact sensor 230 that detects contact with the skin, and the contact sensor 230 may include a pressure sensor or a capacitive sensor.

When the contact sensor 230 is applied to the skin beauty device 10, the light source 410 may be irradiated only when the skin is detected by the contact sensor. In this case, the contact sensor 230 may be disposed on a portion of the upper surface 110. For example, the contact sensor 230 may be disposed on the side of the measurement unit 200 on the translucent cover 430.

By providing the contact sensor 230 as described above, since the light emitted from the light source 410 is irradiated only when it touches the skin, it is possible to prevent the user's vision from being damaged by the light emitted from the light source 410.

In addition, the skin beauty device 10 may include a contact sensor and a distance sensor (not shown) that selectively detects a distance between the light source and the skin.

The distance sensor (not shown) may be disposed on a circuit board on which the light source is mounted. Here, the circuit board may be disposed on the rear side of the transparent cover 430.

When the distance sensor (not shown) is applied to the skin beauty device 10, the light source 410 may be irradiated only when the distance sensed by the distance sensor is within a preset range.

In addition, the skin care device 10 may store information on the amount of moisture and oil of the skin sensed by the measurement unit 200 in the memory 610.

In addition, the skin beauty device 10 recommends the wavelength band of light emitted from the light source 410 and the intensity of the minute current applied from the electrode unit 420 based on the amount of moisture and oil sensed by the measurement unit 200. It may include a control unit 600 that controls to display a plurality of recommended modes on the display unit 300.

In addition, after the measurement unit 200 measures the skin condition and displays the result on the display unit 300, the control unit 600, when the user's skin contacts the contact sensor 230 without a separate manipulation of the user (contact is detected. If so), it is possible to control the operation unit 400 so that the recommended mode is immediately operated.

In addition, the controller 600 controls the light source 410 and the electrode unit 420 to follow the recommended mode displayed on the display unit 300 to apply light having a specific wavelength band to the skin and It can transmit electric current to the skin.

In addition, when the skin beauty device 10 includes a contact sensor 230 or a distance sensor (not shown), the controller 600 may control them.

In addition, the skin beauty device 10 may include an alarm unit (not shown) for notifying the measurement of the skin condition by the measurement unit 200. Here, the alarm unit may include all known means such as LEDs and sounds displayed on the button unit 500.

6 is a flowchart illustrating a method of controlling the skin beauty device of FIG. 1.

A method of controlling the skin beauty device 10 according to an embodiment of the present invention will be described with reference to FIG. 6.

The power of the skin beauty device 10 may be turned on by the button unit 500 (S1).

When the contact sensor 230 detects contact with the skin, the skin condition may be sensed by the measuring unit 200 (step S2). In this case, the indication of completion of the skin condition measurement may be indicated by at least one of an alarm sound, a button unit 500 and light emitted from the display unit 300.

After that, a recommendation mode suitable for the skin condition is determined by the control unit 600, and a recommendation mode suitable for the skin among the recommended modes may be displayed on the display unit 300 (S3). For example, when the skin condition measured by the measurement unit 200 is a lack of moisture state, the display unit 300 may display a blue color and blink to indicate the lack of moisture. Here, the blue color displayed on the display unit 300 may indicate the first recommendation mode.

Thereafter, the notification unit 520 of the button unit 500 displays the same color as the color displayed on the display unit 300, and the operation button 510 changes to a selection mode, or the operation button 510 The recommended mode may be executed by contacting the contact sensor with the skin without operation (S4). For example, when the notification unit 520 displays the same color as the color displayed on the display unit 300, if the skin beauty device 10 is in contact with the skin without manipulating the operation button 510, the contact sensor 230 ) Detects whether or not the skin is in contact, and the recommended mode may be executed. Conversely, when the notification unit 520 displays the same color as the color displayed on the display unit 300, and then selects one of the first to fourth operation modes by operation of the operation button 510, the selection mode is executed. I can.

When the recommended mode is executed, the controller 600 may apply a wavelength band and microcurrent according to the recommended mode to the skin (S5). For example, as the first recommendation mode according to lack of moisture is executed, a first wavelength band of light and a first intensity of a minute current may be applied to the skin.

By operating the operation button 510, the notification unit 520 is manipulated to have a color different from the color displayed on the display unit 300, and when the skin beauty device 10 is in contact with the skin, the contact sensor 230 contacts the skin. Recognizing is the selection mode is executed. When the selection mode is executed, a wavelength band and microcurrent according to the selected mode may be applied to the skin (S6).

While the operation unit 400 is in contact with the skin and light and microcurrent are applied to the skin, the measurement unit 200 can continuously contact the skin to measure the amount of moisture and oil in the skin, and at least one of the amount of moisture and the amount of oil The degree of improvement of may be displayed on the display unit 300 (S7). For example, the degree of improvement in the amount of moisture can be seen as an increase in the number of lights in blue, the degree of improvement in the amount of oil can be seen as an increase in the number of lights in yellow. Can be seen.

When the operation of the operation unit 400 is completed, the degree of skin improvement may be displayed on the display unit 300 (S8). For example, when the operation unit 400 is operated in the first operation mode, the number of lights of the blue color display unit indicating the degree of skin improvement due to water filling may be displayed. Specifically, in the skin condition before the skin care device 10 is operated, one blue-colored indicator flashes indicating lack of moisture, but the skin condition after the skin care device 10 is operated, four blue-colored indicators indicate moisture filling. Can be displayed.

After that, the power of the skin beauty device 10 may be automatically turned off (S7).

By repeating this process for a certain period of time using the skin beauty device 10, skin improvement effects (increase in moisture content, improvement in skin uniformity and transparency, and elasticity improvement) can be obtained.

Hereinafter, the effect of the skin beauty device and the method of using the skin beauty device according to an embodiment of the present invention will be reviewed.

The skin beauty device 10 according to an embodiment of the present invention has an advantage of being able to diagnose a skin condition and improve the skin condition.

In addition, the skin beauty device 10 may provide a customized effect for improving the skin condition by applying light and microcurrent suitable for the skin condition.

In addition, the skin beauty device 10 has the advantage of being able to simultaneously apply light and microcurrents of different wavelength bands.

In addition, when the recommended mode is executed, the color displayed on the display unit 300, the color displayed on the button unit 500, and the color of the light source applied to the skin from the operation unit 400 may be the same. By displaying such a color to have the same color, the user can visually and easily recognize the intensity of light and the intensity of the microcurrent that the user intends to operate.

In addition, since the light source 410 of the operation unit 400 generates light having a predetermined wavelength band and irradiates it to the user's skin, the user has a skin improvement effect (moisture amount increase, skin uniformity) according to the wavelength that penetrates the skin. And transparency improvement, elasticity improvement, etc.)

In addition, when a direct current is applied to the pair of contact electrodes 420a and 420b of the operation unit 400 to ionize the cosmetic product applied to the user's skin, the cosmetic product easily passes through the skin mucosa and introduces ions that penetrate into the skin tissue. Can cause the effect of.

When light in the first wavelength band (400 to 480 nm) and a weak microcurrent are transmitted to the skin, and when the skin beauty device 10 is rubbed on the skin to which the cosmetic is applied, the improvement of the moisture content of the skin may be promoted. In addition, light in the second wavelength band (550 to 610 nm) and microcurrent of the intermediate intensity are transmitted to the skin, and when the skin beauty device 10 is rubbed on the skin to which the cosmetic is applied, the amount of oil on the skin may be improved. In addition, light in the third wavelength band (610 to 650 nm) and a fine current of strong intensity are transmitted to the skin, and when the skin beauty device 10 is rubbed on the skin to which cosmetics are applied, the elasticity of the skin may be improved.

The first electrode 210 and the second electrode 220 may be positioned at the highest portion of the inclined upper surface 110. By being arranged in this way, the user can more easily measure the skin condition since the highest part of the upper surface 110 can be brought into contact with the skin.

By providing a distance sensor or a contact sensor, since the light emitted from the light source 410 is generated only in a state in contact with the skin or within a predetermined distance from the skin, it is possible to prevent a user from seeing the light emitted from the light source 410.

7 is a plan view of a measurement unit and an operation unit according to another exemplary embodiment of FIG. 4 as viewed from above. In the embodiment of FIG. 7 compared to the embodiment shown in FIG. 4, since there is a difference in the shape of the measuring unit and the operation unit, the difference is mainly described, and the description of the first embodiment and reference numerals are used for the same parts.

Referring to FIG. 7, the first electrode 210 ′ and the second electrode 220 ′ may be positioned on the upper surface 110 of the main body 100 and may be disposed in a concentric circle.

Specifically, the measurement unit 200 includes a first electrode 210 ′ oscillating a preset frequency, and a second electrode 210 ′ surrounding the first electrode 210 ′ and receiving a frequency oscillated from the first electrode 210 ′. The electrode 220 ′ may include an insulator that insulates the first electrode 210 ′ and the second electrode 220 ′. In this case, the first electrode 210 ′ and the second electrode 220 ′ may form a concentric circle.

The concentric circle between the first electrode 210 ′ and the second electrode 220 ′ is an insulator, and may electrically insulate the first electrode 210 ′ and the second electrode 220 ′.

In FIG. 7, the first electrode 210 ′ is disposed inside and the second electrode 220 ′ is disposed outside, but is not limited thereto, and the position thereof may be changed.

In addition, the first electrode 210 ′ and the second electrode 220 ′ may be positioned at the highest portion of the inclined upper surface 110. By being arranged in this way, the user can more easily measure the skin condition since the highest part of the upper surface 110 can be brought into contact with the skin.

Hereinafter, a skin beauty device according to another embodiment of the present invention will be described.

The skin beauty device according to the present embodiment has a major difference in the control method of the light source 410 as compared to the above-described embodiment, and the difference will be mainly described.

Since the skin condition of a person is different for each season or for each constitutional characteristic of each individual, when controlling the operating condition of the light source 410 only with a piecemeal logic, any individual in a specific season can use only a specific mode. . Because, in the middle of winter, users with extremely dry skin characteristics have a significantly low oil and moisture value when using the device, and in that case, only blue or yellow light can be irradiated, and in this case, the user can receive red light. You lose the opportunity to be investigated.

Conversely, in the case of oily skin users in the summer, the oil and moisture values are continuously high, and in this case, the user loses the opportunity to receive blue and yellow light irradiation.

As mentioned earlier, the function of each wavelength of LED is only the one that has the most remarkable effect at the corresponding wavelength, and the auxiliary function is not completely absent. Therefore, the cosmetic effect is great for the user to be irradiated with light of various wavelengths. .

Therefore, the wavelength band of light irradiated by the light source 410 according to an embodiment of the present invention is a first color irradiation section (blue), a second color irradiation section (yellow), and a third color irradiation section (red). It is a unit irradiation wavelength section including, and the light source 410 includes the unit irradiation wavelength section at least once, and may be repeated one or more times.

Referring to Table 1 below, the control unit may set to irradiate light of a wavelength band having the same color from the light source of the operation unit even if the range of the result values measured by the measurement unit is different.

Specifically, the light source 410 according to the present embodiment may have an operation sequence in which a unit irradiation wavelength section is repeated twice according to a measurement value measured by the measurement unit 200 as shown in Table 1 below. Here, the condition of the skin is classified by the voltage V measured by the measuring unit 200, but the condition of the skin may be classified according to the measured frequency as described above.

In addition, referring to Table 1 below, the control unit may set to irradiate light of a wavelength band having the same color from the light source of the operation unit even if the range of the result values measured by the measurement unit is different.

For example, a user with a relatively small amount of oil and water according to the characteristics of each season or constitution will have a low measurement value [V] (for example, a level 1 to level 3 section in [Table 1]), A user with a relatively large amount of oil and water will have a high measurement value [V] and corresponds to a high section (eg, level 4 to level 6 in Table 1). Even with such different skin conditions, the user can receive light of various colors by having an operation sequence in which the unit irradiation wavelength section is repeated.

Accordingly, by irradiating the light source of the skin care device according to the present embodiment at least once in a unit irradiation wavelength section, various users having various skin conditions can also receive various light irradiation. The skin beauty device according to the embodiment of the present invention has been described as a specific embodiment, but this is only an example, and the present invention is not limited thereto, and should be construed as having the widest scope according to the basic idea disclosed in the present specification. do. A person skilled in the art may combine and replace the disclosed embodiments to implement a pattern of a shape not indicated, but this also does not depart from the scope of the present invention. In addition, those skilled in the art can easily change or modify the disclosed embodiments based on the present specification, and it is clear that such changes or modifications also belong to the scope of the present invention.
