Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facial beauty device that can automatically distinguish between dryness and wetness of the skin and can always supply an appropriate low frequency voltage.

Recently, portable facial beauty devices that utilize various low frequency voltages have been developed and are gradually becoming popular in households.

In this type of facial beauty device, it is important to always supply an appropriate low frequency voltage to the affected skin.

That is, there are two types of skin: oily and rough, and the electrical resistance of the two generally differs greatly. It is also known that applying a negative voltage to the skin promotes sweating, and conversely, applying a positive voltage suppresses this. Therefore, when applying a negative voltage to oily skin, it will become more oily, and on the other hand, when applying a positive voltage to rough skin, the roughness will increase, so when performing low frequency facial treatment.

Prior to that, it was first necessary to determine whether the skin was oily or rough, and to what extent.

This determination usually requires expensive equipment and experts, so it is easy to buy a commercially available low-frequency facial beauty device and use it to determine if the positive or negative components of the applied voltage are inappropriate for your own skin. Without knowing this, I continued to undergo facial treatments, often resulting in undesirable results.

The present inventor has conducted extensive research into a facial beauty device that has a function of determining the condition of the affected area and automatically selecting and providing an appropriate low frequency voltage by simply touching the affected area, and has arrived at the present invention.

That is, in the present invention, the oscillation voltage of a low-frequency rectangular wave oscillation circuit is applied to a water-retentive sponge roll via an output capacitor, and a differential circuit is formed between a load resistor in contact with the roll and the capacitor, and the load resistor is When the load resistance is high, that is, when it is rough, the negative current component of the output waveform of the load resistance is increased, and conversely, when the load resistance is low, that is, when it is oily, the equal amount of positive and negative current is increased so that the output waveform becomes a completely differential waveform. The present invention relates to a facial beauty device characterized in that it is an ingredient.

The present invention will be explained in detail below.

The rectangular wave oscillation circuit referred to in the present invention may be any known circuit that oscillates a low frequency rectangular wave and whose output voltage is within the range of several tens of ports. For example, an intermittent oscillation circuit such as a blocking oscillation circuit or a relaxation oscillation circuit such as a multi-by-break oscillation circuit can be advantageously used.

The power supply for operating the above circuit is of any type as long as it can operate the oscillation circuit.If the facial treatment is performed permanently in a general household, an inexpensive commercial power supply is advantageous. However, if you carry it with you when you travel and perform facial treatments continuously or intermittently, batteries are appropriate.

The output capacitor usually forms a differential circuit with the resistance component of the skin. When the skin is rough and has a resistance of several hundred kilohms, the negative current component of the voltage applied to the skin, which is the load resistance, increases, and when the skin is oily, the negative current component of the voltage applied to the skin increases. When the resistance component is several tens of kilohms, a completely differential waveform may be provided. That is,
The capacitance C is set to have an appropriate time constant for the width r of the rectangular wave.
All you have to do is set . If the product of the output capacitor capacitance C and the skin resistance component R is made larger, the negative current component of the voltage applied to the load resistance increases, and If it is made large, a completely differential waveform will be given.

As a result of experiments conducted by the present inventor, a range of usually α0001 microfarads to 01 microfarads, preferably 0005 microfarads to α5 microfarads, is suitable. At this time, it is also possible to use a rotary switch or the like to switch among various output capacitors in order to accommodate a wide range of cases.

The water-retaining sponge roll used when applying the low-frequency rectangular wave prepared in this manner to the skin may have sufficient water-retaining properties as needed, but in order to alleviate the discomfort peculiar to electronic therapy as much as possible, Sufficient attention should be paid to its surface treatment. As the material, artificial or natural foamable resin is suitable.

The voltage applied to the water-retentive sponge roll is normally up to several tens of volts, preferably several volts.1゜The facial beauty device according to the present invention does not require any preliminary examination of the properties of the skin prior to the above-mentioned facial treatment. without the need for specific judgment,
You can easily and reliably perform facial treatments. Furthermore, despite these functions, the device itself can be made extremely lightweight, so it has the practical benefit of being able to be freely carried anywhere and perform full-fledged facial beauty treatments intermittently or continuously.

In addition, if necessary, it is equipped with a built-in circuit that can oscillate low-frequency voltages with various waveforms that are effective in treating neurological or muscular diseases, and can be applied to the water-retaining sponge roll using a switch or the like. It is also possible to freely switch the voltage waveform used to perform electronic treatments other than facial cosmetic surgery.

In the following, preferred embodiments of the invention will be explained by means of illustrated non-limiting examples.

First, an example of the rectangular wave oscillation circuit used in the present invention is as follows.
There are a blocking oscillation circuit shown in FIG. 1, a multivibrator circuit shown in FIG. 2, etc.

The rectangular wave voltage obtained from these oscillation circuits is supplied from terminals A and B to load resistor RK via output capacitor 〇. At this time, depending on the value of the load resistance R, the child load resistance R
The output waveform of changes as shown in FIG.

That is, for the reactance component of the output capacitor C, l1
．． When the load resistance R is very large, as shown in FIG. 3A, a rectangular wave voltage 1F approximately equal to the input waveform is not applied to the p-load resistance RK. Also, when the value of the product of the capacitance of the output capacitor C, the L load resistance R, ff[] and the resistance component of the guest approaches the width of the rectangular wave (1, the output waveform of , the negative current component increases as shown in Figure 8.Furthermore, the value of the product of the capacitance of the output capacitor C and the load resistance R1, that is, the resistance component of the skin, becomes smaller than the width τ of the rectangular wave. When the value decreases, the output waveform becomes an almost completely differential waveform as shown in Fig. 8. At this time, the capacitance of the output capacitor 〇 is 001 microfarads, and the load resistance R is 1 in the case of Fig. 3 A. Megohm, 2 in the case of Figure 3 mouth
In the case of 0 kilo ohm, and in the case of Fig. 8 C, it is 5 kilo ohm.

An example of a portable facial beauty device according to an embodiment of the present invention is shown in FIG. In the figure, (1) is the main body, on the surface of which is provided a roll holding stand (2) made of a metal plate or the like, on which a water-retentive sponge roll (3) is supported.

One or more water-retaining sponge rolls (3) are provided. Also, inside the main body (1) is a rectangular wave oscillation circuit (4
) The power supply battery ζ5) is installed inside.

When the facial beauty device of the present invention is configured as described above,
By changing the electrical resistance of the skin, the voltage waveform applied to the skin changes, making it possible to apply a voltage waveform that matches the condition of the skin.

Even for the same person, the degree of oiliness and roughness of the skin usually changes greatly throughout the seasons, and even during the day, so it is difficult to deal with this with conventional devices. However, when using the device of the present invention, it can automatically change according to the current state of the skin and apply appropriate electrical stimulation, making it possible to effectively promote skin metabolism. .

In this way, when the facial beauty device of the present invention is used, it suppresses subcutaneous secretion for oily skin, and conversely promotes subcutaneous secretion for rough skin, rejuvenating the skin, that is, improving facial beauty. It has a remarkable effect.
