The front housing 320 may be coupled to the rear housing 330 to form an internal space. A head 310 and a bar 321 may be coupled to the front housing 320. The head 310 may be coupled to the front housing 320 so that at least a portion is exposed to the outside of the front housing 320. Likewise, the bar 321 may be coupled to the front housing 320 so that at least a portion of the bar 321 is exposed to the outside of the front housing 320.

The head 310 may include one or more action portions 311 and one or more measuring portions 312. Each of the one or more acting parts 311 and the one or more measuring parts 312 may be formed in a shape that protrudes from the externally exposed surface P2 of the head 310. The number and arrangement of the action portion 311 and the measuring portion 312 included in the head 310 may vary. Preferably, as shown in FIG. 5, the head 310 includes four measuring parts 312 arranged in a cross (+) shape on the externally exposed surface P2 of the head 310, and a measuring part It may include four action units 311 each disposed in areas divided by 312. However, embodiments of the present invention are not limited thereto.

The action portion 311 and the measuring portion 312 may include a metal material. Alternatively, the action portion 311 and the measuring portion 312 may include plated plastic material.

Each of the one or more action units 311 and the measurement unit 312 may be individually connected to a substrate, which will be described later. With the head 310 in contact with the user's skin, the action unit 311 can transmit the current generated from the substrate to the user's skin, and the measuring unit 312 can transmit the current flowing through the user's skin to the substrate. there is.

In a state where at least a portion of the action portion 311 is in contact with the user's skin, the action portion 311 applies a voltage to the user's skin to generate a potential difference on the user's skin and flows a current to affect the user's skin. The electrical environment can be changed.

Each of the one or more action units 311 included in the head 310 may individually apply voltage to the user's skin. That is, each of the one or more action units 311 may simultaneously apply voltage to the user's skin, or may apply voltage sequentially.

The measuring unit 312 may transmit a current flowing through the user's skin to a substrate to be described later while at least a portion of the measuring unit 312 is in contact with the user's skin. One or more measuring units 312 may be individually connected to the substrate and individually transmit current.

That is, when power is applied to the user's skin while at least a portion of the one or more operating portions 311 of the skin care device 300 are in contact with the user's skin, the power supplied from the power module 344 is used to control the user's skin. Direct current can be applied to the body, and the user's skin and one or more action parts 311 and one or more measurement parts 312 can form a closed circuit.

The front housing 320 may have a substrate 340 disposed in the internal space formed by the rear housing 330. As shown in FIG. 4B, a fastening portion that couples the front housing 320 and the rear housing 330 may be formed to penetrate the substrate 340.

The resistance measurement module 341 can measure skin resistance by detecting the current received from the measurement unit 312. Human skin is made up of several components, including water, oil, carbohydrates, and natrium. When power is applied to the skin, the current value flowing within the skin varies depending on the amount of moisture within the skin. In this way, the change in the current value flowing within the skin depending on the difference in the amount of moisture within the skin can be expressed as 'skin resistance'. This skin resistance has various values depending on the amount of moisture in the skin. For example, when there is little moisture in the skin, the resistance value of the skin resistance increases and the amount of current flowing through the skin decreases when a predetermined power is applied to the skin. On the other hand, when there is a lot of moisture in the skin, the resistance value of the skin resistance decreases and the size of the current flowing through the skin increases when a predetermined power is applied to the skin. The resistance measurement module 341 may measure skin resistance by detecting a current flowing through the user's skin and generate user skin resistance data based on the measured skin resistance value. Here, the skin resistance data may include information corresponding to one or more of the skin resistance value, the user's age, the user's gender, and the skin resistance measurement period.

The head 310 of the skin care device 300 of the present invention includes one or more action portions 311 and one or more measurement portions 312, thereby enabling more precise measurement of skin resistance. In other words, unlike conventional skin care devices that apply voltage and measure current through a single contact terminal, a person's skin resistance can be measured more quickly and accurately by measuring current using multiple contact terminals.

The control module 342 may receive user skin resistance data from the resistance measurement module 341 and calculate the user's current skin oil level and moisture level based on this data. Oil content and moisture content can be calculated as real numbers between 0 and 100. In this case, the smaller the value, the lower the oil and moisture level of the user's current skin.

The control module 342 receives skin resistance statistical data from the server 500 to calculate the current moisture and oil content of the user's skin based on the user's skin resistance data, and calculates the current moisture and oil content of the user's skin based on the skin resistance statistical data. Moisture and oil content can be calculated.

The power module 344 may apply the generated electrical energy to one or more action portions 311 of the head 310 to send current.

The substrate 340 may further include a driving module (not shown). The driving module may drive the head 310 of the skin care device 300 under the control of the control module 342. Specifically, the driving module may vibrate the head 310. To this end, the head 310 may further include a vibration module (not shown). The control module 342 may change the intensity of the vibration voltage of the vibration module of the head 310 based on the user's skin resistance data. Based on the user's skin resistance data, the control module 342 increases the vibration intensity by increasing the rotation speed of the motor when the user's skin is dry (if the moisture level is low) and when the user's skin is well moisturized. In cases where the moisture level is high, the vibration intensity can be lowered.

That is, the vibration module can adjust the vibration intensity based on the control of the control module 342. As the vibration module vibrates the head 310, the action portion vibrates with at least a portion of it in contact with the user's skin. Accordingly, the absorption of cosmetics applied to the user's skin can be promoted or the discharge of waste products from the user's skin can be promoted.

The bar 321 included in the front housing 320 may include a display module (not shown). The display module may display the user's current skin condition based on the control of the control module 342. The display module can display the user's current skin oil level and moisture level. The display module may include a display (not shown) and a display driver (not shown) that controls the operation of the display. Displays can be implemented in various ways, such as OLED (Organic Light Emitting Diodes), LCD (Liquid Crystal Display), and PDP (Plasma Display Panel).

The bar 321 included in the front housing 320 may include a switch (not shown). The switch may be formed so that at least a portion of the switch is exposed to the outside of the bar 321 so that the switch can be operated by the user.

It is transmitted to the module 341, and the resistance measurement module 341 detects the current flowing through the user's skin, calculates skin resistance, and generates user skin resistance data from the calculated value.

In step S630, the control module 342 of the skin care device 300 receives user skin resistance data and calculates the current moisture level and oil content of the user's skin based on the user skin resistance data.

Moisture and oil content can be calculated. Moisture and oil levels can have real values from 0 to 100.

The method by which the control module 342 calculates the current moisture level and oil level of the user's skin based on skin resistance statistical data is as follows. Skin resistance statistical data refers to data obtained by classifying multiple skin resistance data obtained by measuring the current flowing through the skin of multiple different users into multiple factors including the user's age, gender, and skin resistance measurement period.

The control module 342 compares the measured user skin resistance data with the skin resistance statistical data received from the server 500, and selects a plurality of elements of the user skin resistance data and a plurality of skin resistance data included in the skin resistance statistical data. The coincidence rate of multiple elements can be calculated. The control module 342 may extract the data with the highest matching rate among the plurality of skin resistance data included in the skin resistance statistical data, and calculate the moisture content and oil content based on the data to be extracted.

It may include at least one of the following information. If the information corresponding to the moisture and oil content of the user's skin included in the skin condition data does not match the moisture and oil content calculated in step S630, the control module 342 controls the moisture content and oil content calculated in step S630. The degree can be corrected.

The control module 342 may change the intensity of the vibration voltage of the vibration module of the head 310 based on the moisture level of the user's skin. If the user's skin is dry (if the moisture level is low), the control module 342 increases the vibration intensity by increasing the rotation speed of the motor, and if the user's skin is well moisturized (if the moisture level is high), the control module 342 increases the vibration intensity. Vibration intensity can be lowered.
