On one side of the main body (BODY) of the skin care device, the grounding terminal (X) for the grounding of the finger is exposed to the outside, and the operation indicator lamp (LED ₃ ) to indicate that the device is in operation above it. On the other side of the main body of the skin care device, the function display lamp (LED ₁ ) and the strength display lamp (LED ₂ ) which display each function by color distinction are installed, and each function selection switch ( SW ₁ ), the voltage control switch (SW ₂ ) and the stop switch (SW ₃ ) is installed, the power switch (SW ₄ ) is installed on the side of the skin care body (BODY).

2 shows the basic circuit configuration of the present skin care device, in which the operation of the microcomputer U1 and the power supply circuit 1 for supplying DC power to the microcomputer control circuit U1 as a main component are reset. A reset circuit 2, a switch input circuit 3 for inputting each function, an LED display circuit 4 for visually displaying the operation state of each function, and a voltage of 'low' or ' The intensity control circuit 5 for adjusting the high ', the ion control circuit 6 for changing the flow direction of the anion flowing through the human body, the ion detection circuit 7 and the switching state of the switch to the user It is combined with the buzzer circuit 8 to inform by sound (sound) and constitutes the circuit of this apparatus.

The microcomputer control circuit U1 controls the operation of the device according to a predetermined program as illustrated in the program configuration diagram (flow diagram) of FIG. 4, and the reset circuit 2 is illustrated in the detailed diagram of FIG. As described above, the resistor R ₃ and the capacitor C ₅ are connected to the clock terminal MCLR of the microcomputer control circuit U1.

The reset circuit 3 is connected to the input terminal RB4 of the microcomputer control circuit U1, and has a function selection switch SW ₁ and a voltage control switch that can sequentially select 1-step, 2-step, and 3-step functions. (SW ₂ ) and stop switch (SW ₃ ).

The LED display circuit 4 is a function display lamp (LED ₁ ), a strength display lamp (LED ₂ ) and a resistor (R ₁₃ ) connected to the display terminal (RB1) of the microcomputer control circuit (U1) via a resistor (R5). ) And an operation display lamp (LED ₃ ) connected to the display terminal (RA3) of the microcomputer control circuit (U1) via a transistor (Q ₅ ).

The intensity control circuit 5 outputs the voltage (9V) coming from the power supply circuit 1 as it is or amplifies it and outputs the strong voltage (14V), and the resistor (R ₁₆ ), the capacitor (C ₃ ) ( C ₄ ) and a diode D ₁ (D ₂ ), which is connected to the terminal RA0 of the microcomputer control circuit U1, and the ground terminal X is connected to the + side of the condenser C ₄ .

The ion control circuit 6 is a circuit for controlling the flow direction of negative ions, and consists of two transistors Q ₁ and Q _{2. The} transistor Q ₁ is controlled by a microcomputer through a resistor R ₉ connected to the base side. The transistor Q ₂ is connected to the terminal RA1 of the circuit U1, and the transistor Q ₂ is connected to the terminal RA2 of the microcomputer control circuit U1 through a resistor Q ₁₀ connected to the base side.

The ion detection circuit 7 is composed of a photocoupler PC, a transistor Q ₄ , and a resistor R _14. One side of the photo coupler PC has a strength control circuit 5 and an ion detection circuit 6. It is connected to the other side is connected to the massage district (W). The collector side of the transistor Q ₄ is connected to the display terminal RA3 through a resistor R ₁₁ .

The buzzer circuit 8 is composed of a buzzer B and a resistor R ₁₅ and is connected to terminals RB6 and RB7 of the microcomputer control circuit U1, respectively. The buzzer circuit may output a melody sound by using a melody generating device instead of the buzzer (B).

When explaining the effect of the skin care device of the present invention having such a configuration with reference to the program configuration of the microcomputer control circuit (U1), the power switch (SW ₄ ) protruding on one side of the main body of the skin care device (BODY) of FIG. When 'ON' is turned on, the power is directly output from the battery (not shown) built into the body of the skin care device (BODY) and applied to each circuit element, and the signal is output through the display terminal (RA3) of the microcomputer control circuit (U1). By the conduction of the transistor Q ₅ , the operation display lamp LED ₃ , which is displayed on the surface of the main body BODY, lights up to indicate that the device is ready for operation.

Then, the user performs the skin (face) massage by operating the function selection switch (SW ₁ ). First, apply the cleansing cream evenly and evenly over the neck and face, and then press the function selection position (SW ₁ ) once. (8) The switch switching sound is output through the buzzer (B) constituting the current and the current flows to the LED display circuit (4) so that the green light on the function display lamp (LED ₁ ) is increased so that the skin cleaning massage function as a first step function is performed. Will be displayed.

At this time, the microcomputer control circuit U1 confirms whether the function selection switch SW ₁ is in the 'on' state and at the same time converts it to a mode for realizing the first stage function and maintains this state for a predetermined time (for example, 4 minutes). Let's do it. That is, if you hold the ground terminal (X) of the skin care device body (BODY) by hand and gently rub the massage area (W) on your face, the current will be diode (D ₁ ) (D ₂ ) and resistance (R ₈ ) and photocoupler ( PC) flows from the face to the human body through the hand. In the end, cations attract anionic fat / protein wastes. Toxins and wastes accumulate in the dermis, epidermis, and glandular pores of the skin as anions flow from the hand toward the face. (Toxins and wastes on the skin are fat and proteinaceous, unstable anion molecular state), such as cleansing cosmetics are ionized and pushed out of the epidermis to clean the skin.

Here, if you want to increase the output of negative ions, you can operate the voltage control switch (SW ₂ ). When you press this switch, the intensity indicator lamp (LED ₂ ) changes from green to yellow to indicate that the high voltage has been switched. That is, when a signal is output to the terminal RA1 of the microcomputer control circuit U1 and the transistor Q ₁ is turned on, a voltage of 14 V passes through the photocoupler PC through the capacitor C ₄ and the resistor R ₈ . Strong anion output flows out.

Next, apply the cream on the clean face again and press the function selector switch (SW ₁ ) again. The function display lamp (LDE ₁ ) changes to the other display color with the sound of switching the switch, and the microcomputer control circuit (U1) The mode is converted to the skin movement massage function, which is a two-stage function, which lasts for more than enough time (e.g. 8 minutes) than the first and third stages. In other words, rubbing the massage zone (W) on the face, the flow of ions is stirred from the epidermal layer to the dermis layer and then the dermis layer to the epidermal layer, promoting the regeneration and division of the basal cells, eliminating the waste of the skin and supplying the nutrients at the same time blood circulation The facilitation and collagen fiber tissue is strengthened by the action of ion current agitation, which strengthens the fibrous elasticity (dermis layer), thereby maintaining and maintaining the formation of healthy skin and fine lines.

Next will be described a third step function skin nutrition massage features of the present design, the press and put a nourishing cream evenly function selector switch again to face completing Step 2 Features Features Lamp for display with switching elements (LED ₁₎ is The display color is different from the other stages, and the microcomputer control circuit U1 converts the mode to the skin nutrition massage function, which is a third stage function, so that the state is maintained for a predetermined time (for example, four minutes) less than two stages. In other words, rubbing the massage strip (W) on the face, the current flows from the hand to the face, so nutrient creams containing a large amount of anion are permeated from the epidermis layer to the dermis layer, allowing the ionized cosmetics to easily absorb the dermis layer deep into the skin. The elasticity of the dermal tissue due to sufficient nutrition will keep the skin clear and elastic.

On the other hand, when the intensity indicator lamp (LED ₂ ) in the present skin care device receives a warning light, it indicates the battery replacement time, and the stop switch (SW ₃ ) constituting the switch input circuit ₃ operates the skin care device. It is a switch to temporarily stop the function. In other words, if this switch is pressed while performing the steps 1 to 3, the count function in the microcomputer control circuit U1 is temporarily suspended so that the skin massage can be performed accurately for the predetermined remaining time.

As such, the present invention provides a portable skin care device capable of carrying out skin cleansing massage function, skin movement massage function and skin effect massage function step by step by controlling operation of microcomputer control circuit (U1). It is a new design that further reconsidered the ease.
