Description

[Detailed description of the invention] The present invention relates to an electronic facial beauty device.

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

In this type of electronic 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 properties of the low-frequency voltage required to treat both types are generally very different. It is also known that applying a negative voltage to the skin promotes sweating, and conversely, applying a positive voltage suppresses this.

Therefore, applying a negative voltage to oily skin will make it even more oily, while applying a positive voltage to rough skin will make it even more rough. A positive voltage must be supplied to the latter, and a negative voltage to the latter.

Until now, there are no portable electronic facial devices that can flexibly respond to these conflicting skin demands, and even if they were available, they would be extremely expensive, making it difficult for many women to receive simple and full-scale facial treatment. This was far from the ideal.

The present inventor has conducted extensive research into a simple electronic facial beauty device that eliminates the drawbacks of such conventional devices and can also perform iontophoresis of so-called vitamins, and has arrived at the present invention.

That is, in the present invention, when taking out the rectangular wave output of a low frequency multivibrator oscillation circuit from both ends of the load resistance in the active element of the oscillation circuit,
When passing through an output capacitor, the output is a rectangular wave that alternates between positive and negative, and when the output capacitor is short-circuited with a switch, it is a negative square wave output, and either of the outputs thus obtained is applied to the water-retaining sponge roll. The present invention relates to an electronic facial beauty device.

The present invention will be explained in detail below.

The low frequency multivibrator oscillator circuit used in the present invention has a frequency of 5 to 50 Hz, preferably 10
This is an electronic oscillation circuit that oscillates a low frequency rectangular wave of ~30 Hz either continuously or intermittently with appropriate pause periods. Its output voltage is normally applied up to several tens of volts, preferably within the range of several volts, ie about 1 to 30 milliamps, and is adjusted to obtain a good facial effect. A battery is normally used as the power source, but if the device is permanently installed in a general household or a beauty salon, a commercial power source is advantageous.

The oscillation output is generated by an active element in the circuit, e.g.
It is taken out from both sides of the load resistor on the collector side of the FET or transistor and led to the output capacitor equipped with a shorting switch.When the shorting switch is closed and the output capacitor is shorted, the square wave output of the load remains unchanged. taken out. This output voltage is advantageously used for the treatment of so-called rough skin and for the treatment of vitamins. When performing iontophoresis with this device,
The drug to be iontophorized is made into an aqueous solution or an alcoholic aqueous solution, and is absorbed into a water-retaining sponge roll. The drugs to be iontophorized are various vitamins and other drugs that are said to be effective for beauty, and these are appropriately iontophorized singly or in combination of two or more. In particular, certain aminovinyl photosensitive pigments that have been incorporated into various cosmetics, such as 2,2'[3-[2-(3-heptyl-4-methyl-2-thiazolin-2-ylidene)ethylidene] [Propiophenylene] Bis [3
-Heptyl-4-methylthiazolinium iodide] (trade name: Platonin or Kosensen No. 101, manufactured by Nippon Kanko Shiki Co., Ltd.) is efficiently ion-transferred by the device of the present invention, and is effective in treating spots, freckles, etc. Show effectiveness.

On the other hand, when the short-circuit switch is open and the output capacitor is inserted into the oscillation circuit, a rectangular wave output that alternates between positive and negative is obtained due to the charging and discharging characteristics of the output capacitor. This alternating output voltage can be advantageously used in the treatment of oily skin and in the electronic treatment of neurological or muscular diseases.

The two types of rectangular wave outputs thus obtained are applied to the water-retaining sponge roll. Water-retaining sponge rolls must have sufficient water-retaining properties, but careful attention should be paid to their surface finishing in order to minimize the unique discomfort that has traditionally been associated with electronic therapy. .

The electronic facial device according to the present invention has the practical benefit of being able to supply an appropriate low-frequency voltage depending on whether the patient's skin is oily or rough, thereby enabling easy and reliable facial treatment. .

Moreover, despite its rich functionality, the device itself can be extremely lightweight, allowing it to be carried around freely and used for full-fledged facial treatment intermittently or intermittently.

In this way, the present invention provides reliable results in place of electronic facial beauty devices that cannot necessarily be expected to produce good results because conventional devices are expensive, large, or lack functionality. This brings a lot of good news to elderly women who are concerned about the condition of their skin.

Hereinafter, preferred embodiments of the present invention will be explained using an illustrated example of a portable facial beauty device.

FIG. 1 shows a block diagram of a facial beauty device according to the present invention, in which the oscillation output of a low frequency multivibrator oscillator circuit 1 is connected to a water-retaining sponge roll 2 with or without passing through an output capacitor C.
guided by. When the short circuit switch S is open, the output capacitor C is inserted into the oscillation circuit 1, and the output waveform applied to the water-retaining sponge roll 2 becomes a rectangular wave that alternates between positive and negative as shown in FIG.

On the other hand, when the short-circuit switch S is closed, the output capacitor C is short-circuited, and the oscillation circuit 1 is connected in a direct current manner, the output across the load resistor in the capacity element of the oscillation circuit 1 is directly transferred to the water-retaining sponge roll 2. The output waveform becomes a negative rectangular wave as shown in FIG.

Generally, the equivalent resistance of the skin is from several kiloohms to several tens of kiloohms, so it is preferable that the output capacitor C has a large capacity to reduce its reactance.

This case corresponds to the roughness instruction on the changeover slide switch 5. Furthermore, when the short-circuit switches S ₁ and S ₂ are connected to contacts C and C, respectively, an output capacitor C is inserted into the oscillation circuit 1, and its output waveform becomes a rectangular wave that alternates between positive and negative as shown in Figure 2. The voltage is then applied between the water-retaining sponge roll 2 and the grip 4 of the device body 3. In this case, this corresponds to the oil type instruction on the changeover slide switch 5. In addition, connect short-circuit switches S ₁ and S ₂ to contact RO, respectively.
When connected to RO, the device will stop.

Although the device of the present invention has a simple configuration, it can be effectively used for full-scale facial treatment and for neurological and muscular diseases.

Moreover, since the device of the present invention is extremely lightweight, it can be carried around freely to perform intermittent electronic facial treatment.
