9 is a schematic diagram of an ultrasonic vibration device having an ultrasonic vibration plate and an ion contact electrode at the same time.

As shown in Figure 1 and 2, according to the ultrasonic ion laser skin care device of the embodiment of the present invention, in the present embodiment, but the adapter method is used instead of the charging method, it is also possible to use the charging method. First, when the power switch SW1 is turned on, the DC adapter 101 receives a voltage input through the connection terminals J1 and J3 into the DC-DC converter 120 of the next stage. The voltage from the DC adapter 101 (for example, 3.6V) is boosted to a predetermined voltage (for example, 10-39V) by the DC-DC converter unit 120.

The charging power or the adapter power of the battery is boosted by the DC-DC converter 120 to drive the CPU 102, which in turn is driven by the ultrasonic driver 150 and the body that drive the ultrasonic element to a multi-level level by changing the pulse width. A galvanic driving unit 151 for adding a galvanic ion current to the skin to promote the introduction of an ion active material, a body detecting unit 160 for detecting whether a user's body is in contact with the contact electrode of the galvanic driving unit, and a laser light The laser driver 153 to irradiate, the operation switch unit 130, the display unit 140 for displaying the operating state, and other auxiliary circuit 190 is controlled. Meanwhile, in order to accurately control voltage and reduce power consumption, a battery voltage measuring unit 110 measuring a battery remaining amount and having a battery protection circuit is connected to the battery.

Now, the power supply unit including the DC adapter unit 101 and the switch unit 130, the DC-DC converter unit 120, and the auxiliary circuit unit 190 of the reset unit will be described in more detail with reference to FIG. 2.

When the power switch SW1 is 'on', the FET D9 serving as the switching element is turned on so that the input power from the adapter is applied to the DC-DC converter 120.

In this case, the battery voltage is measured by the battery voltage measuring unit 110 including the voltage dividing resistor R2 and the diode D8 and input to the analog input terminal AN1 of the CPU.

On the other hand, since portable beauty devices usually use a battery of a single input power supply (for example, 3.6V), it is necessary to boost the voltage to a high voltage (20-30V, for example, at this temperature). The converter unit 120 previously used an expensive chip, but in the present invention, as shown in FIG. 2, the PWM of the switching element D6 and the CPU to adjust the output voltage by adjusting the frequency duty ratio Achieved by a control program.

That is, when the switching signal is output from the PWM control terminal (terminal 10) of the CPU, the switching element D6 is turned on / off to control the pulse width, thereby making it possible to control the power of the output voltage. That is, when a user wants to use a beauty device, when the user turns on the power and touches the skin, when the device is used by the body by the body detecting unit 160 to be described later, by lengthening the 'switch-on' time interval of the PWM control signal In this case, the power supply is stepped up to the target voltage during use. This is achieved by using a feedback control method, as shown in (a) of FIG. 7A, so that problems of the related arts such as system down due to sudden voltage rise are solved. In addition, step down also eliminates problems due to a sudden voltage drop, as shown in FIG. 7A (b), by gradually decreasing the pulse width. As a result, stable power management is possible.

In fact, VDD, the output voltage of DC-DC converter, can output 20-30V when using beauty equipment, and power consumption can be reduced by maintaining about 10V when the power is on or not in use.

The divider resistors R3 and R4 sense the output voltage to match the voltage of the CPU (eg, 3.3V) to sense the output voltage sensed by the analog input terminal (AN2).

A power management program of the CPU for implementing the above operation will be described with reference to FIG. 8 is a flowchart showing a control flow for stable voltage control according to the present invention.

First, as shown in FIG. 8, when the pulse width check program PWM_CHECK is started (S1), 'PWM OK FLAG' is checked to check whether PWM control operates by a desired set value (S2). If it works as you wish ('PWM OK FLAG' = 1), return to step S9 and continue. Otherwise, compare the PWM set point ('PWM_TARGET') with the actual PWM value ('PWM_PUF'). (S3), if the value is the same ('PWM_PUF'-'PWM_TARGET' = 0), the process returns to step S9 to continue, otherwise the PWM control steps S4 to S8 are performed.

First, it is examined whether the carry value is 0 (S4), in order to examine whether the duty ratio of the pulse width is larger than the set value. If the set value is smaller than the measured value, the PWM setting is performed (S5) and the PWM value actually applied is increased by a predetermined value to increase the duty ratio (S7). Conversely, if the set value is larger than the measured value, the PWM setting is performed (S6) and the PWM value actually applied is reduced by a predetermined value to reduce the duty ratio (S8).

After that, the process returns to the step S2 to continue the program.

On the other hand, the above-described programmed power adjustment method and apparatus, can also be used to adjust the output intensity of the beauty device. In other words, if the user intentionally adjusts the output from 'weak' to 'strong' by adjusting the third switch SW3, which is the intensity control switching, the analog input terminal AN7 accepts this and inputs the PWM control terminal (pin 10). By applying a PWM pulse width adjustment signal, the duty ratio can be increased to allow the output to be 'strong'. For example, if you want to use the skin care device on the skin of sensitive areas such as the face, you need to weaken the output. On the contrary, if you want to use it on the hip or calf, it is better to increase the output.

On the other hand, the second switch SW2 of the switch unit 130 is a mode switch for adjusting the mode of the beauty device, the fourth switch (SW4) is a step switch for adjusting the step of the beauty device. The external view of these switches is shown in FIG. "Power" switch, "Ultrasound", "Ion", "Laser" drive switch in function, each step drive switch in ion introduction step, "weak", "medium", "strong" level switch in pulse level Giving.

They perform frequency and pulse width conversion on the pulses of the output signals of the analog output terminals of the driving units 150, 151, and 153 described later with reference to FIGS. 4 and 5 so that an appropriate signal is output at each step according to each step. In addition, two levels of intensity (H / L) can be adjusted according to the change in voltage amplitude.

On the other hand, by configuring the switch unit as described above, it is possible to accept various voltages with one input port. Reference numeral 190 denotes a reset section, L1 represents a reactor, C2 and C3 represent a capacitor, and D1-D5 represents a reverse protection diode.

Now, the galvanic driver 150, which is the core of the present invention, will be described with reference to FIG. First, the pulse waveform control signal from the output terminal RB7 of the microcontroller 102 is amplified by the amplifying circuits U3A, R31, R33, R35, and R37, and integrated circuits U3B, R32, R38, R39, R29, and C9. , C10), and then are applied to the contact electrodes J6 for the face and the contact electrodes J7, J8 for the hand through the resistors R34 and R36, respectively. As will be described later, the contact electrode for the face is a cover of the ultrasonic vibrator.

At this time, the PWM control signals from the input / output terminals RB3 and RB2 of the microcontroller are applied to the PWM control transistors Q5 and Q6 through the resistors R54 and R55, respectively, and the collector sides of the transistors Q5 and Q6 are respectively face and face. Connected to the contact electrode of the hand, the output waveform forms a triangular waveform as shown in FIG. 7B according to the PWM control signal. That is, when the signal of the terminal RB2 is 'high', the transistor Q55 is in the 'on' state, and the knob connection electrode is in the ground state, so that an output between t0-t1 in FIG. 7B occurs, and conversely, When the signal is 'high', the transistor Q5 is turned 'on' and the face connection electrode is grounded, so that an output between t1 and t2 in FIG. 7B is generated. Eventually, galvanic current flows alternately from face to hand or from hand to face, and the ion active material can be effectively introduced into the skin.

In addition, the member number 160 of FIG. 5 is a body detecting unit for detecting whether the electrode is in contact with the skin. The sensed signal is amplified by the amplifier circuits U3C, U3D, R42, R44, R46, R48, R49, R53, C11, and C12, and then to the microcontroller 102 via analog input terminals AN5 and AN6. Is entered.

Now, with reference to Figure 4, other functions of the beauty device according to the present invention will be described in detail. First, the laser driver 153 receives a signal from the first laser output terminal AN0 of the microcontroller 102 to the photodiode PD and the laser diode LD, which is the second laser output terminal PWM1. Is controlled by the switching of the switching transistor Q1. The remaining D10, R7, R8, R9, R1, C5, C1 are additional elements.

Next, the ultrasonic driver 150 applies a control signal from the output terminal AN3 of the microcontroller 102 to the switching transistor Q4 through the diode D16 and the resistor R22, thereby resonating the transistor Q3. In addition, the ultrasonic driver ULTRA1 is driven together, and the remaining elements R16, R18-R20, R23, L3-L5, C7-C11, and D9 are peripheral circuits of the transistors Q3 and Q4 and the ultrasonic driver. .

On the other hand, in the present invention, as shown in Figure 9, by adopting a plate-shaped ultrasonic vibrator, it has been improved so that low noise, high vibration and failure rate almost.

Preferably, it is effective that the ultrasonic vibration function proceeds simultaneously when the ion function is used, and the laser function can be used independently. The galvanic ion function and the laser function can also be used at the same time.

Next, a configuration of the display unit 140 of the present invention will be described with reference to FIG. 3. The first and second LEDs D11 and D12 of FIG. 3 are connected to the first input / output terminal RD0 of the control device CPU. And the second input / output terminal RD1 are connected in parallel in opposite directions to each other, and the third and fourth LEDs D16 and D17 of FIG. 3 are connected to the second input / output terminal RD1 and the third of the control device CPU. The input and output terminals RD2 are connected in parallel in opposite directions to each other, and the fifth and sixth LEDs D21 and D22 of FIG. 3 are connected to the third input / output terminal RD2 and the fourth input / output terminal R of the control device CPU ( RC6) are connected in parallel in opposite directions to each other, and a seventh LED (D15 in FIG. 3) is connected between the first input / output terminal RD0 and the fourth input / output terminal RC5 of the control unit CPU, and the eighth LED is connected. And a ninth LED (D25 and D26 of FIG. 11) are connected in parallel in opposite directions between the fourth input / output terminal RC6 and the fifth input / output terminal RC5 of the control unit CPU, wherein each of the LEDs is Control station Value is independently turned on / off by the signal value for each of the input / output terminals.

The first to sixth LEDs D11, D12, D16, D17, D21, D22, D25, and D26 may be cleansing, massage, nutrition, lifting, whitening, or whitening. And a soft galvanic ion step, wherein the seventh LED (D15) is used to indicate the use state of the skin care device, and the eighth and ninth LEDs (D25, D26) Used to indicate the strength and weakness of external functions. Of course, even in the galvanic ion step, it is possible to adjust the intensity of each mode.

In addition, the LED D27 indicating the ion introduction step informing the driving of the galvanic driver and the LED D28 informing the driving of the laser driver are connected to the output terminals RC4 and RC3.

Light emission conditions of each LED of the display device 140 of the above embodiment are shown in Table 1 below.

On the other hand, as described above, in order to have both an ion introduction function and an ultrasonic vibration function effectively, it is preferable that they are made of one element, Figure 9 is a schematic diagram of the ultrasonic vibration element having an ultrasonic diaphragm and an ion contact electrode at the same time As shown in (a), the laminates for the ultrasonic vibrations are separated, (b) shows the cover of the ultrasonic vibration element, and (c) shows the combined state thereof.

As described above, these functions must be as shown in FIG. 9 for simultaneous operation. That is, for the ultrasonic vibration function, an ultrasonic vibration ceramic (a1) having a + plate on one side and a-plate on the other side, a flexible PCB (FPCB) (b1, b2, c1) and an ultrasonic vibration and ion transfer head (d1) are required. In addition, the FPCB requires SUS (c1) for insulating between the microadhesive copper plates b1 and b2 on both sides. In addition, since the cover (d1) of the diaphragm has a surface (d2) capable of transmitting ultrasonic vibrations, it functions as a + electrode in the ion introduction function (the electrode becomes a finger when introducing the ion), so that the ion current can be transferred. It is preferable to become.

In principle, if the bonding surface is placed between the copper plates on both sides of the FPCB, the bonding surface forms an insulating layer, so that the ultrasonic and ions can be used simultaneously, but because the actual bonding surface is micrometer dimension, the current is conducted. Therefore, an insulating material having sufficient insulation effect should be used. The insulator must be thin enough (several tens of micrometers) to sufficiently transmit ultrasonic energy and to withstand high temperatures (120 degrees) when bonding both copper plates. As such a material, a polyimide film (65 um), polyester (70 um), or the like is preferable.

The above is merely described based on one embodiment of the present invention, and various modifications are possible without departing from the technical spirit of the present invention. Therefore, the present invention should be construed as limited only by the following utility model registration claims.

As described above in detail, according to the ultrasonic device according to the present invention, since the ultrasound function and the iontophoretic function can be performed at the same time, it is possible to maximize the cosmetic effect, and there is an advantage that the device is also simplified.

In addition, according to the beauty device that employs the ultrasonic element and detects the body, it senses that the contact electrode is placed on the skin and only boosts it to the actual operating voltage, thereby minimizing unnecessary power consumption. It is convenient because it can know whether it is in use or not.
