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

1 and 2 illustrate a mat for microcurrent stimulation according to an embodiment of the present invention.

As shown, the microcurrent stimulation pillow of the present invention is composed of an outer shell 11 having a cushion material 12 embedded therein.

The outer shell 11 is made of a non-conductive material such as general fiber, natural or artificial leather, and the outer shell 11 is made of a material that is harmless to the skin, such as a cotton fabric, since the outer shell 11 is a part directly contacting the skin.

The cushion member 12 embedded in the shell 11 may be made of cotton, sponge, or the like to impart cushioning properties.

At least one magnetic pole member 15 is disposed on the surface of the shell 11, and each magnetic pole member 15 has a predetermined area and may be provided over the entire surface or a part of the surface of the shell 11.

The magnetic pole member 15 according to an embodiment may be made of a conductor such as a conductive rubber or a conductive metal, and the magnetic pole member 15 of a conductive material may be attached to the surface of the outer shell 11 through an adhesive or the like. The micro current is transmitted to the head, neck, and shoulder of the human body through the stimulus member 15 to smooth the metabolism and blood circulation of the cells, thereby actively utilizing the user's health, various treatments or massage purposes.

The microcurrent generator 150 is electrically connected to the magnetic pole member 15 so that the microcurrent generated by the microcurrent generator 150 is transmitted to the human body through the magnetic pole member 15.

The operation of the present invention as described above will be described in detail as follows.

It is known that a microcurrent of about 0.06 mA flows in the human body, and the strength of the microcurrent varies depending on the state of health. In general, a phenomenon in which the amount of microcurrent flows in a poor state of health is known clinically.

Thus, by stimulating the microcurrent from the outside having a size enough to stimulate the human body may contribute to the internal balance. In addition, although there is a slight difference depending on the sense level of the body, it is generally known that a current of about 1 mA can be sufficiently perceived, and a long time energization is known to be undesirable.

Therefore, if the size of the microcurrent is less than 1 μs to a few hundreds of amps, it may be suitable for the massage or treatment, and it may be desirable that the microcurrent flows intermittently for a certain period of time instead of continuous flow to give electric stimulation. .

Figure 3 is a block diagram showing a microcurrent generator according to the present invention. As shown, the microcurrent generator 150 of the present invention includes a control unit 310, a boosting unit 320, and a microcurrent output unit 330.

The control unit 310 is a first control signal (S1) for generating a fine current having a positive phase, a second control signal (S2) for generating a fine current having a negative phase, and for boosting the power supply voltage The third control signal S3 is generated to control the generation of the microcurrent. The control unit 310 checks the level of the microcurrent supplied to the human body through the microcurrent generator 150 and controls the third control signal S3 to adjust the level of the boosted voltage when the level is not a predetermined level. By varying, the human body supply level of the microcurrent is controlled.

The control unit 310 may include a control chip having a CPU to generate the first to third control signals S1, S2, and S3.

The booster 320 boosts the power voltages Vdd and Vcc to a boosted voltage of a predetermined level in response to the third control signal S3 of the control unit 310 to the microcurrent output unit 330. Supply.

The booster circuit constituting the booster unit 320 includes a booster circuit of a DC-DC converter type using a back electromotive force of an inductor, a charge pump circuit using a capacitor, and to those skilled in the art. Various well known boost circuits can be used.

The microcurrent output unit 330 generates a microcurrent of a desired level based on the boosted voltage boosted by the booster 320 and supplies the microcurrent to the specific site of the human body through contact terminals in contact with the human body. .

The microcurrent output unit 330 supplies the microcurrent having a positive phase when the first control signal S1 is input, and a negative phase when the second control signal S2 is input. Supply the microcurrent having a.

Here, the microcurrent is a current level of 0 to 1000 mA (not including 0) and refers to the micro current in microamps. The microcurrent output unit 330 is generated by selecting any current level determined to have the highest therapeutic effect or massage effect among the current levels of 0 to 1000 mA (not including 0). For example, a fine current of 0 to 300 μA or a fine current of 100 to 150 μA.

In order to generate the microcurrent, the microcurrent output unit 330 includes at least one voltage distribution circuit and a plurality of switching elements, and each of the plurality of switching elements may include the first control signal S1 or the first control element. The switching operation may be performed in response to the two control signal S2.

The microcurrent can be varied in response to the skin resistance of the human body used to make the level of the microcurrent actually supplied to the human body constant.

To this end, the microcurrent output unit 330 generates a supply level confirmation signal for confirming the human body supply level of the microcurrent supplied to the human body and provides it to the control unit 310, and the control unit 310 provides the In response to the supply level confirmation signal, the level of the boosted voltage of the booster 320 is controlled.

Here, the supply level confirmation signal provides a function for confirming whether the condition for supplying the microcurrent is actually made in contact with the human body in addition to the function for confirming the level of the microcurrent actually supplied to the human body.

4 is a circuit diagram illustrating an example of implementation of the microcurrent generator of FIG. 3.

As shown, the control unit 310a is a control chip (for example, PIC16F716) (U2), resistor (R4), capacitor (C4), power (Vcc), LED to determine whether the power supply ( Including the D2) has a wiring structure as shown in FIG. The control chip U2 is capable of generating control signals having various kinds of frequencies.

As illustrated in FIG. 3, the control unit 310a may include a first control signal S1 for generating a microcurrent having a positive phase, a second control signal S2 for generating a microcurrent having a negative phase, And generating a third control signal S3 for boosting the power voltage to control the microcurrent generation.

In addition, the control unit 310a receives the supply level confirmation signal MC for confirming the human body supply level of the microcurrent supplied to the human body provided by the microcurrent output unit 330a to receive the booster 320a. The level of the boosted voltage VC can be controlled. The level control of the boosted voltage VC is possible through the third control signal.

Although the control unit 310a checks the human body supply level of the microcurrent through the supply level confirmation signal MC, it is also possible to check whether the human body contact terminals P1 and P2 actually contact the human body. . This is because it is possible to determine that the human body contact terminals P1 and P2 are in contact with the human body if the supply level confirmation signal MC is within a range corresponding to the skin resistance because the range of the human body's skin resistance is determined. Here, the body contact terminals P1 and P2 correspond to the magnetic pole member 15.

Therefore, when power is supplied, the control unit 310a first checks whether the human body contact terminals P1 and P2 are in contact with the human body through the supply level confirmation signal MC, and whether a microcurrent is generated. It is decided. That is, when it is confirmed that the human body is contacted through the supply level check signal MC, the microcurrent is generated through the microcurrent generator, and then the function of confirming the actual human supply level of the microcurrent is performed.

Since the control unit 310a has to be movable and portable, the power supply voltage may be configured to be supplied through a battery.

The booster 320a may include a switching element Q7, which is repeatedly switched by the third control signal S3 generated by the control unit 310a, an inductor L1, rectification and ripple prevention, and boost voltage. A diode D1 for storage, capacitors C1 and C2, and a resistor R10 have a wiring structure as shown in FIG. 4. In this case, a transistor is used as the switching element Q7, but various switching elements including a MOSFET may be used.

As shown in FIG. 6, the boosting unit 320a may be configured through a boost circuit of a DC-DC converter type having the boost stage 10 formed in multiple stages, and may include various boost circuits such as a boosting circuit. It is possible to implement

 The microcurrent output unit 330a includes a plurality of voltage dividers using a plurality of resistors R1, R6, R2, R7, R8, and R9 and a plurality of switching elements Q1, Q2, Q3, Q4, Q5, and Q6. ) To output a microcurrent to the human body contact terminals (P1, P2). The plurality of switching elements Q1, Q2, Q3, Q4, Q5, and Q6 use transistors, but various switching elements including MOSFETs may be applied.

Some switching elements Q6 and Q3 of the switching elements Q1, Q2, Q3, Q4, Q5 and Q6 are controlled by the first control signal S1, and some switching elements Q5 and Q4 are controlled. Is controlled by the second control signal S2, and the remaining switching elements Q1 and Q2 are controlled by the voltage of the first node n1, that is, the boosted voltage VC.

The human body contact terminals P1 and P2 are mounted on specific parts of the human body (sites requiring treatment or massage), and the second human body contacts the microcurrent applied through the first human contact terminal P1 through the human body. It may be configured to return to the terminal (P2), or to allow the micro-current applied through the second human contact terminal (P2) to pass through the human body to return to the first human contact terminal (P1).

5 is a timing diagram of the control signal and the fine current of FIG. 4.

Hereinafter, the operation of the microcurrent generator of FIG. 4 will be described with reference to the timing diagram of FIG. 5.

First, the microcurrent generator 150 operates while the human body contact terminals P1 and P2 of the microcurrent generator 330a of the microcurrent generator 150 are mounted on a specific part of the human body.

When power is supplied through a battery, the control unit 310a generates a signal for confirming whether the human body is in contact with the microcurrent output unit 330a or the third control signal S3 for generating a general microcurrent. In addition, the supply level confirmation signal MC is received to check whether the human body contact terminals P1 and P2 actually touch the human body.

This is because when the level of the supply level confirmation signal MC is positioned within a predetermined range in consideration of the skin resistance of a general human body, it is possible to determine that the human body is in contact with the human body.

Thereafter, the control unit 110a supplies the third control signal S3 for generating a microcurrent to the boosting unit 320a. The third control signal S3 is a control signal whose width and period are adjusted for step-up.

When power is supplied through a battery, the control unit 310a supplies the third control signal S3 to the boosting unit 320a. The third control signal S3 is a control signal whose width and period are adjusted for step-up.

When the third control signal S3 is applied, the switching element Q7 of the boosting unit 320a is turned on / off in response to the third control signal S3.

When the switching element Q7 is turned on, the current of the inductor L1 starts to increase, and the diode D1 is turned off because the bias is applied in the reverse direction, thus the inductor The voltage (L1) becomes equal to the power supply voltages Vcc and Vdd. When the switching device Q7 is turned off by the third control signal S3 again, the current of the inductor L1 starts to decrease, and accordingly, the voltage of the inductor L1 The polarity is changed to merge with the power supply voltage. This voltage is stored in the capacitor C1.

In this case, a forward bias is applied to the diode D2, and the capacitor C2 stores a voltage output through the diode D2, and the voltage of the output voltage, that is, the boosted voltage VC, is on. Eliminate pulsations (ripples).

When the next switching operation is performed, a voltage corresponding to twice the voltage stored in the capacitor C1 is stored in the capacitor C2. When a plurality of switching operations are performed in this manner, the first node n1 ) Generates a boosted voltage VC several times to several ten times higher than the power supply voltages Vcc and Vdd. For example, assuming that the power supply voltage is 3V, it becomes possible to obtain a voltage of 30V. Of course, it is also possible to generate a higher level of voltage.

That is, when the switching device Q7 repeatedly performs the on / off operation according to the width and the period of the third control signal S3 of the control unit 310a, the boosted voltage VC has a desired level. .

When the boosted voltage VC reaches a desired level, the control unit 310a generates a first control signal S1 and a second control signal S2. The first control signal S1 and the second control signal S2 may be generated at the same time as the supply of the power supply voltage of the control unit 310a, but it does not mean that the boosted voltage VC reaches a desired level. Therefore, it is assumed here that it occurs when the boosted voltage VC reaches a desired level.

The first control signal S1 is for generating a micro current having a positive phase, and the second control signal S2 is for generating a micro current having a negative phase.

When a microcurrent having a positive phase and a negative phase is generated and supplied to the human body, the treatment and massage effects are known to be superior to those of the microcurrent having only a positive phase.

The first control signal S1 is shown in FIG. 5. It may have a waveform structure of the pulse (pulse) having a certain period and a certain duty ratio (duty ratio). For example, it may have a waveform structure having a constant voltage level for a time of 150 ms with a period of 1 second, and a voltage level of 0 for the remaining time.

However, this is just one example. In consideration of the effective aspect of treatment or massage, the period or duty ratio may be changed by a unit of time, and the period or duty ratio may have a different waveform structure.

The second control signal S2 may have a waveform structure in the form of a pulse having a certain period and a constant duty ratio in a form having a predetermined phase difference from the first control signal S1. The second control signal S2 has the same shape except that it has a predetermined phase difference from the first control signal S1.

Here, the second control signal S2 should have a voltage level of 0 in a time interval t1 in which the first control signal S1 has a constant voltage level, and the first control signal S1 has a voltage of 0. In some sections of the time section T-t1 having the level, the waveform structure has a constant voltage level.

That is, the pulse of the first control signal S1 and the pulse of the second control signal S2 are generated so as not to overlap. That is, the timing at which the switching elements Q6 and Q3 are turned on by the first control signal S1 and the timing at which the switching elements Q5 and Q4 are turned on by the second control signal S2 should be different. Immediately after the switching elements Q6 and Q3 are turned on by the first control signal S1 and turned off again, the switching elements Q5 and Q4 are turned on by the second control signal S2. The switching elements Q6 and Q3 are turned on by the first control signal S1 and then turned off again, and after a predetermined time, the switching elements Q5 and Q4 are turned on by the second control signal S2. It is also possible to turn on. This is possible by controlling the timing of the pulse generation of the second control signal S2, and may be determined differently as necessary in consideration of treatment or massage effects.

When the boosted voltage VC reaches a predetermined level, the microcurrent output unit 330a turns on the switching element Q1 by the voltage divided by the voltage distribution of the resistors R1 and R6. The voltage divided by the voltage distribution of R2 and R7 turns on the switching element Q2. This is possible when the switching elements Q5 and Q6 are turned off. When the switching element Q6 is turned on by the first control signal S1 even when the boost voltage VC reaches a predetermined level. When the switching device Q2 is turned on and the switching device Q1 is turned off and the switching device Q5 is turned on by the second control signal S2, the switching device Q1 is turned on and switched. Element Q2 is turned off.

When the first control signal S1 and the second control signal S2 are applied to supply the fine current, fine current supply starts.

When the switching devices Q6 and Q3 are turned on by the first control signal S1 and the switching devices Q5 and Q4 are turned off by the second control signal S2, the switching device Q2. ) Is turned on, and the microcurrent is supplied to the human body through the switching element Q2 and the human body contact terminal P1 at the first node n1, and the microcurrent supplied to the human body is the human body contact terminal P2 and It is recovered through the switching element Q3 and the resistors R8 and R9. At this time, the switching elements Q5, Q4, and Q1 are turned off by the second control signal S2. At this time, the microcurrent supplied to the human body has a positive phase, as shown in the microcurrent graphs P1-P2 of FIG. 5.

Thereafter, when the switching devices Q6 and Q3 are turned off by the first control signal S1 and the switching devices Q5 and Q4 are turned on by the second control signal S2, the switching device Q1. ) Is turned on, and the microcurrent is supplied to the human body through the switching element Q1 and the human body contact terminal P2 at the first node, and the microcurrent supplied to the human body is the human body contact terminal P1 and the switching element ( Q4), it is recovered through the resistors R8 and R9. At this time, the switching elements Q6, Q3, and Q2 are turned off by the first control signal S2. At this time, the microcurrent supplied to the human body has a negative phase, as shown in the microcurrent graph P1-P2 of FIG. 5.

As already described, the level of microcurrent supplied to the human body is different for each human body because the skin resistance is different for each human body. Therefore, in order to enhance the massage or therapeutic effect, it is necessary to check the level of microcurrent actually supplied to the human body because microcurrents within a certain level range must be supplied.

Therefore, the microcurrent output unit 330a has a configuration capable of controlling the level of the microcurrent supplied to the human body by checking the level of the microcurrent recovered through the human body contact terminals P1 and P2.

It is possible to use the voltage corresponding to the microcurrent or the microcurrent flowing through the resistors R8 and R9 as the supply level confirmation signal MC for confirming the human body supply level of the microcurrent supplied to the human body.

The supply level confirmation signal MC may send a microcurrent flowing through the resistors R8 and R9 to the control unit 310a, and is distributed through voltage distribution of the resistors R8 and R9 as shown in FIG. It is also possible to use the supplied voltage level as the supply level confirmation signal MC.

The supply level confirmation signal MC is provided to the control chip U2 of the control unit 310a, and when the supply level confirmation signal MC is provided, the control unit 310a analyzes the supply level confirmation signal MC to the human body. It is confirmed whether the level of the microcurrent actually supplied is the desired level.

If the level of the microcurrent actually supplied to the human body is within the desired level range, no separate operation is performed, but if the level of the microcurrent is out of the desired level range, the boosting unit 320a is boosted through the third control signal S3. The level of the voltage VC is controlled.

When the level of the boosted voltage VC is controlled, the level of the microcurrent actually supplied to the human body through the human body contact terminals P1 and P2 is changed, and the control through the control unit 310a is controlled by the human body. The level of microcurrent actually supplied is continued until the desired level range is reached.
