Description

Skin Beauty Machine {A DEVICE FOR TREATING THE SKIN TROUBLE}

The present invention relates to a skin care device, and more particularly, to a complex skin care device that can be generated by merging several elements that provide a net action to skin care.

The various elements that have a net effect on the skin care are those that comprise at least far infrared rays, ultrasonic waves, and vibration devices.

As is known, one of the devices used in skin care is a skin care device developed to improve absorption of cosmetics by using ion action.

Skin beauty machine by the ion action is expensive and at the same time large appearance is not easy to buy and use universally.

At the same time, such a skin care device is complicated and difficult to operate, while the effect is simple and does not have many problems in use.

On the other hand, in order to improve the shortcomings of the beauty machine depending on the ionic action as described above has been devised a beauty machine using a low frequency. According to the Republic of Korea Patent Publication No. 96-14098, it is formed to achieve a five-step operation of tightening, incorrect, twisting, knocking and repeating while varying the output state of the low frequency to manage obesity and partial carcass of the belly and waist, It is to remove the waste by.

According to the prior art, only the skin care by the simple electrical stimulation and the ion action by the low frequency is possible, so the action as a beauty device for skin care is very insufficient.

The electrical stimulation due to the low frequency increases the fatigue of the skin muscle strength when a certain time is exceeded, rather it causes the aging of the skin. Therefore, the user must use the time strictly according to the time. There are drawbacks that can be counterproductive by the anticipation that overuse will be more effective.

After all, the prior art method of using low frequency as a skin care device is a limited technique inevitably reduced its usefulness.

The present invention has been made to solve the problems of the prior art as described above to provide a more effective skin care device.

An object of the present invention is to provide a skin beauty device in which skin beauty effect is maximized by deep penetration of skin and far infrared rays activating cells of the human body.

The present invention provides a skin care device that promotes the decomposition and removal of foreign substances and metabolism by removing various problems by applying a combination of various elements by far infrared rays, ultrasonic waves and vibration.

The ultrasonic waves are sounds of high frequency that cannot be heard by the human ear, and when such ultrasonic waves are fired in the liquid, the waves propagate into the liquid while the contraction and expansion occur alternately in the liquid.

The further increase in the ultrasonic energy breaks the cohesion between molecules of the liquid and generates tens of millions of fine cavities. This is called cavitation, and the energy is released as the cavity explodes. This shock wave cleans the surface of the waste remaining in the skin layer and deep inside the skin in a short time without damage.

In addition, the far-infrared ray is a light of a longer wavelength than the infrared ray, especially the far-infrared ray of 4-20 microns is known to be easily absorbed by the human body, and when the far-infrared ray is absorbed, blood vessels are expanded to promote blood circulation and promote waste products and metabolism. This happens.

The present invention is a central processing unit including a microcontroller for controlling at least the entire circuit to provide a beauty device for managing the skin mainly by ultrasound and far-infrared rays known as useful as described above, and inputs an external signal to the central processing unit A switch input having a plurality of key switches, an ultrasonic output unit for generating first and second outputs having different output intensities under the control of the central processing unit based on the input external signal, and relaxation of skin tension For outputting the first and second outputs having different intensities, a far infrared output unit generating far infrared rays, a display unit displaying their selected states and setting times, and supplying DC power to all the circuits. It is made by including the power supply part.

The present invention forms a power supply unit 10 including a down transformer T1, a full-wave rectifying bridge diode D2, and regulators U3 and U4 from a commercial AC voltage to provide driving power to all circuits to be described later.

In the present invention, all operations are performed under the control of the central processing unit 20 including the 8-bit microcontroller U1.

A predetermined control step is stored in the microcontroller U1 to drive the ultrasonic output unit 34, the far infrared output unit 31, and the vibration output unit 33 in response to a control request provided from a switch input from the outside. do.

In order to achieve stable detection of the switching level with the switch SW1 for setting a time limit, an ultrasonic output control switch SW2, a far infrared ray output switch SW3, and a vibration output switch SW4 as an external input to the microcontroller U1. Resistor R3 to R4 and capacitors C4 to C7 are connected to each switch to form a switch input unit 21.

The infrared output unit 31 is connected to the far infrared output ports RXD of the microcontroller U1 by connecting the far infrared diodes D5 and D6 (D7 and D8) in parallel to the buffers U7B and U7C, respectively.

On the other hand, the vibration output unit 33 connects the noise removing inductor L1, the vibration motor M1, and the switching transistor Q1 from the power supply terminal Vcc and through the resistors R13 and R14, the microcontroller U1. ) To the vibration output port (TXD).

The ultrasonic output unit 34 is configured to generate a soft first output and a strong second output. The ultrasonic output unit forms an input terminal with a plurality of diodes D3 and D4 to generate the first and second outputs, and connects a power supply Vcc to an input terminal of a current amplification buffer U7A and a 15V power source to an output terminal. To form an output terminal (JP1) in which a plurality of analog integrated circuits (U8A to U8F) are formed in series and parallel, and connected to the ultrasonic output port (WR) of the microcontroller (U1) to the diode (D3) of the diode input terminal. do.

In addition, the display unit 35 for displaying the user's external input setting state and the current control state on the microcontroller U1 is formed of 7 segments of a light emitting diode.

Light emitting diode LED1 displays the first output of the ultrasonic waves, LED2 displays the second output of the ultrasonic waves, LED3 displays the far infrared output, and LED4 and LED5 display the strength and weakness of the vibration microcontroller (U1). ) Are connected to the output ports (P2.0 ~ P2.4). In addition, the seven segments F1 and F2 display unit units and ten units, respectively, by connecting the output ports P0.0 to P0.7 to the microcontroller through the drivers U5 and U6.

The control process of the present invention as described above will be described with reference to FIG.

According to the present invention, the microcontroller is initialized when power is applied to the skin care device for the first time, generating an ultrasonic wave, far infrared ray, and vibration output, an operation time setting step of setting a duration of the output, and when the operation time setting is set. A setting time display step of displaying the setting time limit in the seven-section, a setting change detection step of detecting a change in the selected output element, a setting confirmation step of confirming the changed setting if the setting is changed, and a change Recognizing the setting in the microcontroller, displaying the changed setting on the display unit, an output control step in which the microcontroller controls each output unit according to the set external input, detecting the progress of the set time limit, When the set time limit has elapsed, the operation waits and the control process is returned. It is carried out.

The action made by the present invention described above will be described in more detail below.

According to the present invention, when the user opens a skin beauty device as illustrated in FIG. 4, the user grips a handle (not shown) in which ultrasonic waves, far infrared rays, and vibrations are generated, and turns on the power switch SWp. It is full-wave rectified and forms constant voltages 15V and 5V via regulators U4 and U3.

The driving of the power unit causes the light emitting diode D10 to light to inform the user of the power connection.

When the power is applied, the microcontroller of the skin care device is initialized.

After that, the first ultrasonic wave (low intensity), the far infrared ON (ON), the output of the vibration 1 stage is made and selected by operating the corresponding switches (SW2 ~ SW3) as needed.

When the switch is selected, the microcontroller U1 detects the switch input as an external input and outputs a corresponding driving element.

For example, the ultrasonic wave can generate two outputs with different output intensities, and the vibration is also made to control the intensity.

The output is complex depending on the selected output element and the strength of the selected output.

When the output according to the selection is made, the operation time setting step of determining and inputting how long the output is to be maintained is inputted by using the operation time setting switch SW1. The unit consists of 5 steps of 3 minutes, 5 minutes, 7 minutes, 10 minutes and 12 minutes, and this setting time limit is displayed on the 7-segments F1 and F2 of the display unit 35.

When the selected elements of the ultrasonic wave, the far infrared ray, or the vibration are output alone or in combination during the set time, when there is a setting change to change the time or change the selected elements during use, the microcontroller U1 detects this and checks the preset setting. Recognizing the changed setting and displaying the change on the display unit 35, the output of the microcontroller is controlled by the changed setting, and the output of ultrasonic waves, far infrared rays, vibration, etc. is controlled and output.

After the time elapses, it is detected whether the time limit for outputting the set elements ends, and when the time expires, control is performed to block the output of all the output elements and return to the operation standby state.

The operation of the ultrasonic output unit 34 according to the present invention will be described in detail (see FIGS. 2 and 5).

The output of the ultrasonic output unit has a plurality of outputs having different intensities as a first output and a second output.

The first output may be referred to as a soft type, and the second output may be referred to as a rough type.

The ultrasonic output unit is provided with a diode D4 having an input via the diode D3 and an oscillation frequency of the oscillator OS2 U2 as an input to an output terminal WR of the microcontroller U1.

The oscillator U2 generates an oscillation frequency of 5 V and 1 MHz, and this oscillation is used as a clock which is a reference for all control.

In the case of being set as the first output, the oscillation frequency is output as a square wave of 5V and 500Hz through the output terminal UTR_OUT; WR of the microcontroller U1, and this output is 5V, while passing through the buffer U7A. 1MHz waveform is output in 5V, 500Hz section.

That is, in one cycle of the square wave of 500 Hz, half of the interval is composed of 1 MHz pulse and the output of zero ("0") V is repeated in the other half.

After the 12V power supply is pulled up to the output terminal of the buffer U7A, the output of the same frequency waveform amplified to 15V is formed through the analog integrated circuits U8A to U8C, and the analog integrated circuits U8D to U8F. ) Form the output of the same frequency opposite waveform amplified to 15V. Thus, ultrasonic vibrations are generated.

A second output that is relatively stronger than the first output will be described.

In the case of being set as the second output, the frequency of the oscillator is equal to 1 MHz, and at this time, the output voltage UTR_OUT; WR of the microcontroller U1 outputs a constant voltage of 5 V DC without a wave.

The output terminal (UTR_OUT; WR) signal of the microcontroller U1 is output as a signal of 1 MHz that is the same as the oscillation frequency of the oscillator U2 via the buffer U7A, and the signal is passed through the analog integrated circuits U8A to U8F. It is amplified and output as a symmetrical waveform so that the ultrasound is output equally over the entire section in 1MHz period.

Therefore, a second output that is relatively stronger than the first output is generated.

The first type of ultrasonic output, which is a soft type, is suitable for the beauty of the face and when used in combination with a cleansing gel, penetrates deep into the skin (about 40 mm from the epidermis) to remove foreign substances, minimize fat cells, and circulate blood. And will act to promote metabolism.

On the other hand, the second output is a rough type of stronger wavelength than the face is provided with a strong ultrasonic wave for the purpose of removing the flesh on the part of the waist, legs, calf, etc., where the skin layer is rather thick.

In addition, the far-infrared output unit 32 of the present invention receives the 5V, 1KHz output of the microcontroller to operate the far-infrared diodes (D5 ~ D8) by using the current amplification action of the buffer (U7B, U7C) emits far infrared rays.

The far-infrared doubles the effect of the ultrasound and promotes blood circulation, blood purification, and warming the body's own intrinsic nerve function.

In addition, the vibration output unit 33 adjusts the vibration stage under the control of the microcontroller using the vibration motor M1 to cause vibration, so that the vibration stage 1 is suitable for performing a cleaning function, and in the vibration stage 2, It is suitable for performing massage and lifting functions.

All these controls are under the control of the microcontroller and each control step is presented to the user via a light-emitting diode and a seven-segment display.

As described in detail above, the present invention provides a number of elements useful for skin beauty such as ultrasound, far-infrared, and vibration by limiting a function limited to any one action such as low-frequency stimulation or anion, as in the conventional skin care device. Because it can be applied in a complex, there is an effect that can maximize the effect as a skin beauty machine.

In addition, by applying the efficacy of medically recognized ultrasound and far-infrared rays, it is effective to discharge foreign substances in the skin easily by using ultrasonic vibration of about 100,000 times per second and deep penetration of far-infrared skin. It can be widely applied to slimming of the face and skin troubles by facilitating the decomposition elimination action and blood circulation and metabolism.

Therefore, like conventional slim-up devices, it is possible to reduce the burden on the body by reducing the size of fat cells and reduce the burden on the body rather than discharging fat to the outside of the body or temporarily draining moisture.

By applying such elements such as ultrasonic wave, far infrared ray, vibration, etc., it causes resonance and resonant action with organic matter (especially water molecule) in the skin, which improves resistance to diseases of nerves, bones and joints, and improves blood circulation. It is a very excellent invention, such as the effect of further enhancing the metabolism and making the skin elastic.
