Description

Skin beauty apparatus using ultrasonic waves

The present invention relates to a skin care device using ultrasonic waves, in particular, it is normally operated when the skin is in contact, and automatically minimized when the skin is not in contact, so that overheating of the ultrasonic output unit is effectively suppressed, and the power saving function is greatly improved. It relates to a skin care device used.

As shown in FIG. 1, the skin care apparatus using ultrasonic waves is operated and controlled by the main processor MP, and the ultrasonic generating unit converts the driving electricity from the power source into ultrasonic waves and outputs the ultrasonic waves to the ultrasonic output unit UO. (UG) and; Ultrasonic output unit (UO) is vibrated by the ultrasonic wave from the ultrasonic generating unit (UG), and outputs the vibration force by the ultrasonic wave to the outside; Skin contact unit (SC) attached to the ultrasonic output unit (UO), vibrating with the ultrasonic output unit (UO); A decompression unit TR for decompressing driving electric power from a power supply and transmitting it to the main processor MP; A main processor MP which is operation controlled by the input unit I to control the operation of the ultrasonic wave generation unit UG; It has a structure consisting of an input unit (I) for controlling the operation of the main processor (MP). In the present embodiment, the input unit (I) is used only the button type ON / OFF operation switch (SW1), but can be made of a combination of several types of switches in accordance with the addition of the function, of course, the ultrasonic output As the unit UO, a piezoelectric element is mainly used.

When explaining the operation state thereof, first, when driving electric power (normally 12V electric) from the power supply is supplied to the skin care device, the driving electric power from the power supply is directly supplied to the ultrasonic generating unit UG, while the decompression unit is supplied. The drive electricity decompressed to the low voltage by TR is supplied to the main processor MP. At this time, the ultrasonic wave generation unit UG and the main processor MP maintain the operation standby state, and the operation switch SW1, which is the input unit I, also receives the driving electricity from the main processor MP to maintain the operation standby state. Will be maintained. In this state, when the user operates the operation switch SW1, the main processor MP is operated to be controlled by the control signal from the operation switch SW1, and the ultrasonic signal generating unit generates a control signal according to a preset control value. (UG), and the ultrasonic wave generation unit (UG) is operated by the setting control signal of the main processor (MP) to output the ultrasonic wave having a predetermined frequency to the ultrasonic output unit (U0). When ultrasonic waves are input to the ultrasonic output unit UO, the electrical energy to the ultrasonic output unit UO is converted into dynamic vibration energy through the ultrasonic output unit UO, and the ultrasonic output unit UO corresponds to the input ultrasonic waves. ) Is vibrated quickly, and the skin contact unit (SC) attached thereto is also vibrated quickly together with the ultrasonic output unit (UO). On the other hand, when the operation switch SW2 is re-operated, the main processor MP is operated controlled by the control signal from the operation switch SW1, so that the output of the control signal to the ultrasonic wave generation unit UG is stopped. The operation of the ultrasonic wave generation unit UG by the control signal from the main processor MP is stopped, and the operation of the ultrasonic output unit U0 and the skin contact unit SC is also stopped.

When the fast contacting the skin contact unit (SC) to vibrate close to the body part, the skin contact unit (SC) is quickly vibrating while physically tapping the contacted body part, the physical skin beauty effect by the ultrasound, the massage effect , Collagen metabolism improvement, cell and tissue cleansing action as already known. On the other hand, when the ultrasonic output unit (UO) and the skin contact unit (SC) is quickly vibrated, as the internal energy is increased, some of the dynamic vibration energy is converted into thermal energy, so that the ultrasonic output unit (UO) and the skin contact unit (SC) Since the temperature of the self is continuously rising, it can be expected that the thermal heating effect (blood circulation stimulation, lymph flow stimulation, vascular strengthening). In addition, chemical effects such as increased ATP activity, promoting skin regeneration, regulating skin ph balance, and activating skin can be obtained.

However, in the skin care apparatus using ultrasonic waves according to the related art, a method for preventing overheating of the ultrasonic output unit UO and the skin contact unit SC cannot be devised, so that the skin contact unit SC is overheated. As a result, the user may feel uncomfortable or severely burned. In addition, overheating of the ultrasonic output unit UO frequently causes circuit damage of the components UG, MP, SW1, and TR constituting the skin care device.

In order to solve this problem, conventionally, the driving time of the skin care device is counted, and when the skin care device is continuously driven for a predetermined time, the skin care device is automatically stopped. In this case, the shorter the driving time, the more inconvenient to use, and the longer the driving time, the greater the risk of overheating. Therefore, it is important to set the driving time until the skin care device is automatically stopped. Since it is practically impossible to set an appropriate driving time due to differences in habits, conditions of use, and environment of use, there is a limit to solving the problem due to overheating.

2, the temperature sensor (TS) is installed in the skin contact unit (SC), when the temperature of the skin contact unit (SC) rises above the set temperature, the driving of the skin care device automatically A way to stop is proposed. In the present embodiment, although the temperature sensor TS is installed in the skin contact unit SC, the temperature sensor TS may be installed in the ultrasonic output unit UO.

When the operation state of the skin is roughly described, when the power is supplied to the skin care device, the temperature sensing sensor TS is operated by the driving electricity from the power supply, and the temperature sensing sensor TS of the skin contact unit SC is used. The temperature detection value is continuously output to the main processor (MP).

In this state, when the operation switch SW1 which is the input means I is operated, the ultrasonic wave generating unit UG is operated by a control signal according to the set control value of the main processor MP, and the ultrasonic wave generating unit ( Ultrasonic output unit UO vibrates by ultrasonic waves from UG. When the temperature detection value from the temperature sensor TS is equal to or higher than the set temperature, the control from the main processor MP to the ultrasonic wave generating unit UG is performed. By stopping the signal output, driving of the ultrasonic wave generation unit UG and the ultrasonic wave output unit UO is stopped. After that, when the temperature detection value from the temperature sensor TS becomes lower than the set temperature, the control signal output from the main processor MP to the ultrasonic wave generating unit UG is resumed, and the ultrasonic wave generating unit UG and the ultrasonic wave are restarted. Restart the output unit (UO).

In the case of the skin care device, since the overheating of the ultrasonic output unit UO and the skin contact unit SC can be prevented appropriately, the above problems caused by the overheating thereof are eliminated.

However, such a skin care device is also designed to operate continuously regardless of whether or not the skin care device is used once the skin care device is operated, which causes unnecessary power waste. Moreover, rather than effectively preventing the temperature rise of the ultrasonic output unit UO and the skin contact unit SC, the operation of the ultrasonic wave generation unit UG and the ultrasonic output unit UO is controlled only by their overheating state. Since it is a way to stop operation due to overheating occurs frequently during use, a problem that is cumbersome and inconvenient to use.

The present invention is devised to solve the above problems, it is normally operated when the skin is in contact, the minimum operation automatically when the skin is not in contact, so that the overheating of the ultrasonic output unit is effectively suppressed, the power saving function is greatly improved An object of the present invention is to provide a skin care apparatus using ultrasonic waves.

The present invention for achieving the above object, the operation is controlled by the main processor, an ultrasonic wave generating unit for converting the drive electricity from the power source to the ultrasonic wave and outputs it to the ultrasonic output unit; An ultrasonic wave output unit vibrated by ultrasonic waves from the ultrasonic wave generation unit, and outputting vibration force by ultrasonic waves to the outside; A skin contact unit attached to the ultrasonic output unit and vibrating together with the ultrasonic output unit; A decompression unit for decompressing driving electric power from a power supply and transmitting it to the main processor; A main processor controlled by the input unit to control the operation of the ultrasonic wave generating unit; In the skin care device using the ultrasonic wave consisting of an input unit for controlling the operation of the main processor, the voltage detecting sensor for detecting the voltage value of the ultrasonic wave transmitted from the ultrasonic wave generating unit to the ultrasonic output unit is provided to the main processor It is a structure characterized by the above-mentioned.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

According to Figure 3 is a skin care device according to the present invention, the operation is controlled by the main processor (MP), the ultrasonic generating unit (UG) for converting the drive electricity from the power source to the ultrasonic wave output to the ultrasonic output unit (UO) And; Ultrasonic output unit (UO) is vibrated by the ultrasonic wave from the ultrasonic generating unit (UG), and outputs the vibration force by the ultrasonic wave to the outside; Skin contact unit (SC) attached to the ultrasonic output unit (UO), vibrating with the ultrasonic output unit (UO); A decompression unit TR for decompressing driving electric power from a power supply and transmitting it to the main processor MP; A main processor MP which is operation controlled by the input unit I to control the operation of the ultrasonic wave generation unit UG; An input unit I for controlling the operation of the main processor MP; The voltage detection sensor VS detects the voltage value Vx of the ultrasonic wave transmitted from the ultrasonic wave generation unit UG to the ultrasonic output unit UO and outputs it to the main processor MP.

The voltage detection sensor VS detects the voltage value Vx of the ultrasonic wave transmitted from the ultrasonic wave generation unit UG to the ultrasonic output unit UO and outputs the voltage value Vx to the main processor MP. In order to prevent damage to the circuit, all of the known ones that can remove the high peak value out of the predetermined range while applying the voltage value from the ultrasonic generator UG having a relatively high voltage are applicable.

For example, in the present embodiment, as shown in Figure 4, after receiving the ultrasonic voltage from the ultrasonic generating unit (UG) to the ultrasonic output unit (UO), after filtering it to output only the + value of the ultrasonic voltage Diode D; Resistors and / or variable resistors R1 and R2 for reducing the + voltage from the diode D; A capacitor C for smoothing the + voltage reduced by the resistors and / or the variable resistors R1 and R2; If the + voltage value from the capacitor C exceeds the preset voltage range, the maximum voltage value Vmax is output to the main processor MP, and the + voltage value from the capacitor C is preset. When it is within the range of the voltage value, a voltage compensating sensor VS is used, which consists of a comparator VC for outputting the + voltage value to the main processor MP.

Referring to the operation state of the skin care device according to the present invention, first, when supplying a driving electric power (normally 12V electricity) from the power supply to the skin care device, the driving power from the power supply to the ultrasonic generating unit (UG) While directly supplied, drive electric power (normally 5 V of electricity) which has been decompressed to a low voltage by the decompression unit TR is supplied to the main processor MP. At this time, the ultrasonic wave generation unit UG and the main processor MP maintain the operation standby state, and the operation switch SW1, which is the input unit I, also receives the driving electricity from the main processor MP to maintain the operation standby state. Will be maintained. In this state, when the user operates the operation switch SW1, the main processor MP is operated controlled by the control signal from the operation switch SW1, so as to control the control signal according to the preset minimum control value (Fig. 5A). Reference) is output to the ultrasonic wave generating unit UG, and the ultrasonic wave generating unit UG is operated by a control signal from the main processor MP, so that the ultrasonic wave output unit U0 is separated from the ultrasonic wave generating unit UG. The minimum vibration is caused by the minimum ultrasonic waves, and the ultrasonic voltage from the ultrasonic wave generation unit UG to the ultrasonic wave generation unit UO is input to the voltage detecting sensor VS. In this case, it is reasonable to consider that the ultrasonic wave output from the ultrasonic wave generating unit UO is not to actually operate the ultrasonic wave output unit UO but to detect whether a part of the body is in contact with the skin contact unit SC. If a part of the body is in contact with the skin contact unit (SC), the load is applied to the ultrasonic output unit (UO) a lot, the low voltage is input to the voltage sensor (VS), while the skin contact unit ( If a part of the body is not in contact with the SC), since the load is not applied to the ultrasonic output unit UO, a high voltage is input to the voltage detection sensor VS. Thereafter, when the detected value from the voltage detection sensor VS input to the main processor MP is less than or equal to the set value, ultrasonic generation of a control signal (see FIG. 5B) according to the preset control value set in the main processor MP is performed. Output to the unit UG so that the ultrasonic wave generation unit UG and the ultrasonic output unit UO operate normally, and the detection value from the voltage sensor VS input to the main processor MP exceeds the set value. When the main processor MP outputs a control signal (see FIG. 5A) according to a predetermined minimum control value to the ultrasonic wave generating unit UG, the ultrasonic wave generating unit UG and the ultrasonic wave output unit UO are operated at minimum. Be sure to That is, when a part of the body is in contact with the skin contact unit (SC), the skin care device is normally driven, and if a part of the body is not in contact with the skin contact unit (SC), the skin care device is driven minimally.

On the other hand, the control signal from the main processor (MP) takes the form as shown in Figures 5a and 5b, where "P" represents the pitch of the control signal, "T1" represents the signal generation time, " T2 " represents the delay time (no signal generation time). When the driving electricity to the main processor MP is 5V, the voltage at the signal generation time T1 is 5V, the frequency thereof is generally 60Hz, and the ultrasonic wave from the ultrasonic wave generation unit UG is 1MHz. It is common. In the case of the control signal according to the minimum control value, it is preferable to determine a value that can sense the load during skin contact, but to make it as minimum as possible. In this embodiment, the signal generation time (T1) is set to 1.5 ms. (When the frequency is 60 Hz, one pitch (P) is about 16.5 ms).

Thereafter, when the operation switch SW2 is re-operated, the main processor MP is operated to be controlled by the control signal from the operation switch SW1, so that the output of the control signal to the ultrasonic wave generation unit UG is stopped. The operation of the ultrasonic wave generation unit UG by the control signal from the main processor MP is stopped, and the operation of the ultrasonic output unit U0 and the skin contact unit SC is also stopped.

According to the present invention, if the skin care device is not used after being operated, that is, if the skin contact unit (SC) does not come into contact with the body, the operation is virtually stopped while consuming only the minimum power for detecting the use of the skin care device. Therefore, overheating of the ultrasonic output unit UO and the skin contact unit SC is effectively prevented and power consumption is reduced.

Meanwhile, in order to prevent overheating of the ultrasonic output unit UO and the skin contact unit SC, as shown in FIG. 6, after counting the operating time tx, the operating time tx is the reference time t. Of course, if the elapsed over the skin can be automatically stopped the operation of course.

The present invention can be applied to various applications based on the embodiment shown in FIG. 3, which is described below with reference to FIG. 7 as an example thereof.

LED3) and a buzzer B for outputting audible sound waves according to the operating state of the skin care device are used, but a display such as a general liquid crystal monitor may be used as a visual output means. The light emitting diodes are representative of the light emitting units LED1, LED2, and LED3.

In addition, the ultrasonic generation is set for each mode, and the mode selection switch SW2 for selecting a mode other than the operation switch SW1 is used as the input means I, and the mode selection switch SW2 is operated to select a mode to be driven. Afterwards, when the operation switch SW1 is operated, the ultrasonic wave generation unit UG and the ultrasonic wave output unit UO may be driven by a control signal according to the mode setting control value from the main processor MP. In the present embodiment, the first mode generates the signal generation time T1 at 30% of the pitch P, the second mode generates the signal generation time T1 at 60% of the pitch P, and the third mode the signal. The generation time T1 was set to 90% of the pitch P.

In this case, the light emitting unit constituting the output unit O includes an operation display unit LED1 for displaying the operation state of the operation switch SW1 and a mode display unit LED2 for displaying the operation state of the mode selection switch SW2. It is composed of

On the other hand, by installing a power switch (PSW) in the power line, the drive electricity from the power source may be selectively supplied or cut off by the operation of the power switch (PSW), of course, to configure the output unit (O) By reinforcing and installing the power display unit LED3 in the light emitting unit, the user can visually check whether the driving electric power is supplied from the power source.

The buzzer B is configured to output a set sound when the driving electric power from the power source is first supplied and when the input unit I is operated, so that the user can visually recognize the operation state of the skin care device. You can do it.

According to the present invention as described above, the voltage detection sensor for detecting the voltage value of the ultrasonic wave transmitted from the ultrasonic wave generation unit to the ultrasonic output unit and outputs it to the main processor is provided, the ultrasonic output according to the body contact Due to the difference in the load of the unit, the skin care device is normally operated when the body is in contact with the body, and the skin care device is minimized when the body is not in contact with the body, so that the overheating of the ultrasonic output unit is effectively suppressed and the power saving function is greatly improved.
