1 is an exemplary diagram showing the schematic configuration of a skin care device according to an embodiment of the present invention.

As shown in FIG. 1, the skin care device according to this embodiment includes a main body 100 and a plurality of cartridges 200 and 300 that can be coupled to (or detached from) the main body 100.

The main body 100 includes a sensor module 110, a battery 120, a processor 130, a communication module 140, a location display module 150, a power generation module 160, and a cartridge coupling unit 170. do.

The first cartridge 200 can perform moisture measurement and radio frequency (RF) skin care, and the second cartridge 300 can perform plasma skin care.

At this time, although not specifically shown in the drawing, cartridges capable of performing other types of skin care may be additionally included.

The sensor module 110 includes an acceleration sensor (not shown) for detecting the movement of the main body 100 (e.g., direction of movement for massage), and the degree to which the cartridges 200 and 300 are in contact with the skin and adhere to the skin ( It includes a touch sensor (not shown) and a pressure sensor (not shown) to detect intensity.

At this time, some of the sensors of the sensor module 110, although not shown in the drawing, may be included in the cartridges 200 and 300.

The battery 120 supplies driving power to the main body 100 and the cartridges 200 and 300, making them portable.

The processor 130 exchanges signals (eg, control signals, measurement signals, etc.) with the cartridges 200 and 300 coupled to the main body 100.

For example, the processor 130 controls the first cartridge 200 to measure moisture or perform high-frequency skin care, and controls the second cartridge 300 to perform plasma skin care.

In addition, the processor 130 communicates with the user terminal 400 and displays the cartridges 200 and 300 in the user's self-image (e.g., face) displayed through an app installed on the user terminal 400. Massage information (e.g., massage position, massage type, massage intensity (pressure), etc.) performed through the combined body 100 is transmitted and displayed in an overlap manner.

For example, as shown in FIG. 6, the processor 130 provides a massage method for each part (e.g., massage type, massage direction, A guide image that guides the massage intensity (massage intensity) is displayed in an overlap method, and information on the massage actually performed by the user (e.g., massage position, massage type, massage intensity (pressure), etc.) is additionally overlapped by referring to the guide image. It can be displayed as . At this time, the processor 130 recognizes the facial part in the user's self-image (e.g., face), and even if the user's self-image is shaken, the processor 130 provides the guide image and information on the massage actually performed by the user. Accurately overlaps the self-image (e.g. face).

The communication module 140 communicates with the user terminal 400 to collect information detected through the sensor module 110 (e.g., massage information, etc.) and information detected through the cartridges 200 and 300 (e.g. : moisture information, cartridge status information, etc.) are transmitted.

The location display module 150 monitors the movement (position) of the main body 100 combined with the cartridges 200 and 300 when taking a self-image (e.g. face) of the user captured through the camera of the user terminal 400. ) can be detected.

For example, the position display module 150 may be an LED of a specific color (eg, red) installed on one side of the main body 100 or the cartridges 200 and 300.

The power generation module 160 generates power during massage using the skin care device (e.g., the main body 100 combined with the cartridges 200 and 300) according to this embodiment.

For example, the power generation module 160 performs power generation during massage using a harvesting material that generates power using triboelectric energy, or a piezoelectric element that generates power using microvibration, and uses the generated electricity to generate electricity in the battery ( By charging 120), the operating time of the skin care device according to this embodiment can be extended.

The cartridge coupling portion 170 is formed to physically and electrically couple the cartridges 200 and 300 to the main body 100.

The oscillator 210 of the first cartridge 200 oscillates a signal (or current) at a designated frequency and outputs it to the first electrode, and the amplification unit 220 oscillates a signal (or current) at a designated frequency through the first electrode. The output signal is transmitted through the skin to amplify the signal input through the second electrode, and the detector 230 detects only the signal of the specified frequency from the amplified signal and transmits it to the processor 130.

Accordingly, the processor 130 converts the signal into a digital signal (ADC: Analog to Digital Convert) and measures moisture based on the voltage level of the signal (e.g., the voltage level of a specified number of signals). At this time, the measured moisture value may be expressed as a ratio (%) compared to a preset standard.

The processor 130 may check whether the first cartridge 200 or the second cartridge 300 is coupled.

For example, cartridges coupled through serial communication between the processor 130 and the cartridges 200 and 300 can be distinguished, or cartridges can be distinguished through specific terminals that output different voltage values for each cartridge when coupled.

At this time, although not specifically shown in the drawings, the cartridges 200 and 300 each include a microprocessor (not shown) including a communication function, and communicate with the processor 130, thereby enabling the processor 130 to The operation of the cartridges 200 and 300 can be controlled.

The voltage generator 310 of the second cartridge 300 generates and outputs a signal of a specific level (e.g., 5V), and the booster 320 outputs the signal output from the voltage generator 310. The voltage is boosted to a high voltage and output to the discharging dielectric 330, and the current detection unit 340 detects the current output from the boosting unit 320 and transmits it to a microprocessor (not shown), so that the plasma voltage and current are The resonance frequency and period (Tc) for driving the booster unit (e.g., high-voltage transformer) are adjusted to maintain the specified value (see FIGS. 4 and 5).

FIG. 2 is a flowchart for explaining the moisture measurement method in FIG. 1.

Referring to FIG. 2, when a signal is detected through the second electrode (yes in S101), the processor 130 starts (drives) a measurement timer (e.g., 10 seconds) (S102).

In addition, the processor 130 determines that when the signal is above a specified level (example in S103), the slope of the voltage level of the specified number of signals (e.g., the value converted from the specified number of pulses (AC signal) to a DC voltage level) is specified. If it is within the value (±2.0 degrees) (i.e., a stable voltage level is maintained for more than a specified time (e.g. 1 second)) (example of S104), the measurement time (e.g. 10 seconds set in the timer) is not exceeded. If not (No in S105), the measurement is determined to be successful and the measured value (i.e., the measured moisture value) is transmitted wirelessly (e.g., Bluetooth, WiFi, etc.) to the communication-connected user terminal 400 (S106).

However, if the measurement time (e.g., 10 seconds set in the timer) is exceeded (example in S105), the processor 130 may determine that the measurement has failed and perform the measurement again (S107).

FIG. 3 is a flowchart for explaining a method of controlling plasma output in the second cartridge in FIG. 1, FIG. 4 is an exemplary diagram showing an I-V curve for a general plasma discharge, and FIG. 5 is a flow chart in FIG. 1. , This is an example diagram shown to explain how to adjust the output period (Tc) of the resonance frequency for driving the booster to maintain the Normal Glow Region area of the plasma discharge.

Referring to FIG. 3, according to the command of the processor 130, the microprocessor (not shown) of the second cartridge 300 generates a designated resonance frequency (e.g., 37 kHz) (S201) and boosts the booster 320. A high voltage is generated through the current detection unit 340, and the current output from the booster 320 is detected (S202), and the detection current and the preset reference current (i.e., the plasma discharge voltage is measured in the Normal Glow Region region) (S203), if the detection current and the reference current are the same (i.e., within the error range) as a result of the comparison, the resonance frequency and period (Tc) for driving the booster (e.g. high voltage transformer) ) is maintained (S204), and if the detection current and the reference current are different as a result of the comparison (i.e., outside the error range), that is, depending on whether the detection current is smaller or larger than the reference current, the booster (e.g., high voltage transformer) increases or decreases the driving resonance frequency and period (Tc) (S205).

In Figure 1, in Figure 1, a guide image guiding the massage method for each part is displayed in an overlapping manner on the user's self-image captured through the camera of the user terminal, and information on the massage actually performed by the user is additionally overlapped. This is an example diagram shown to explain the display method.

Referring to FIG. 6, the processor 130 communicates with the user terminal 400 and displays the user's self-image (e.g., face) displayed through an app installed on the user terminal 400. Information on the massage actually performed using the skin care device according to is additionally displayed in an overlap manner.

Additionally, the processor 130 transmits moisture information measured from the user's skin to the user terminal 400 and displays it on one side of the screen.

Additionally, the processor 130 transmits information on the elapsed time of a massage performed using the skin care device according to this embodiment to the user terminal 400 and displays it on one side of the screen.

In addition, the processor 130 refers to the guidance image displayed on the screen of the user terminal 400 and detects massage information (e.g., massage position, massage type, massage intensity (pressure), etc.) that the user actually performs. By delivering it to the user terminal 400, it can be displayed in an overlap manner in addition to the guide image.

At this time, the massage intensity (pressure) can be displayed in color.

For example, if the massage intensity (pressure) is below the standard range, it may be displayed in yellow, if the massage intensity (pressure) is above the standard range, it may be displayed in red, and if the massage intensity (pressure) is within the standard range, it may be displayed in blue.

In addition, the processor 130 recognizes facial parts in the user's self-image (e.g., face), and even if the user's self-image is shaken, the processor 130 provides the guide image and information on the massage actually performed by the user. It moves along the self-image (e.g. face) and overlaps it accurately.

When the user's face area is recognized as described above, a guidance image guiding the massage method (e.g., shape, direction, intensity, etc.) corresponding to each part of the user's face is displayed in an overlap manner (S303) (see FIG. 6) .

Additionally, when skin moisture is detected (example in S304) (i.e., when skin moisture measurements are received from the processor 130), the user terminal 400 displays moisture information on one side of the app ( S305) (see Figure 6).

Additionally, when the user actually performs a massage using the skin care device according to this embodiment (example in S306), the user terminal 400 tracks the location of the moving location display module 150 in the image and provides guidance. Displays whether the massage method guided through the image matches the actual massage information (i.e., displays the part where the massage was performed and the part where the massage was not performed) (S307) (see FIG. 6).

Here, the location display module 150 (e.g., LED of a specific color) is a means for recognizing the user terminal 400 through an app, and is detected through the sensor module 110 from the processor 130. When massage information is received, the received information may be additionally used to indicate whether it matches the massage method guided through the guidance message.
