Description

  The present invention relates to a beauty device.

  Since it was reported that a high-frequency current was applied to the skin to improve skin troubles, high-frequency beauty equipment using a pair of electrodes has been used in the beauty industry.

  When the current flowing between the electrodes concentrates on the same skin region, discomfort such as pain occurs in the skin, and therefore, there is a technique for suppressing such discomfort by using a pair of parallel electrodes. . Patent Literature 1 discloses a high-frequency beauty device using a pair of annular electrodes having different diameters. Patent Literature 2 discloses a cosmetic device including a plurality of circular electrodes and electrodes formed along the circumference of the electrodes.

Patent No.6212603 JP2017-077314

  However, since the electrode of the high-frequency beauty device disclosed in Patent Document 1 is a ring-shaped electrode, when the high-frequency beauty device is used on the skin to which the serum is applied, the electrode is surrounded by the ring-shaped electrode. There was a problem that the serum was collected in the space. If the serum accumulates in the space surrounded by the ring-shaped electrodes, the ratio of the high-frequency current passing through the serum increases, and the efficiency of applying the high-frequency current to the skin decreases.

  The inventor of the present invention has solved the problem that the serum is accumulated in a space surrounded by the ring-shaped electrodes by providing a gap in the ring-shaped electrodes to solve the above problem. However, it has been found that when a gap is provided in the annular electrode, the subject feels discomfort due to the contact between the electrode end and the skin in the gap. If the discomfort is reduced by increasing the width of the ring-shaped electrode and increasing the contact area between the electrode end and the skin, the increased electrode width reduces the area where high-frequency current is applied to the skin. Occurred.

  In addition, the electrode of the cosmetic device disclosed in Patent Literature 2 is curved between the electrodes, so that the problem that the cosmetic liquid stays is solved, but the efficiency of discharging the cosmetic liquid from between the electrodes is too high, and the electrode There is a problem in that the serum tends to run out in the central part, causing unevenness in the cosmetic treatment.

  The inventor of the present invention has observed the actual usage of the high-frequency beauty device in detail, and has noticed that the user uses the high-frequency beauty device by repeating the movement in the circular direction and the movement in the vertical direction. Developed an electrode shape that uses this repetitive movement in the circular and vertical directions to prevent the serum from staying between the electrodes, while also keeping the serum between the electrodes moderately and continuing to apply it on the skin properly The present invention has been completed.

  In the ion output in the cleansing mode, both the electrodes 100 and 200 and the hand electrode 300 are energized, a positive pulse voltage is applied, and every time a predetermined time (8.1 ms) elapses, a predetermined negative voltage is applied. A voltage (voltage level 1: 7 V, voltage level 2: 8 V, voltage level 3: 9 V, voltage level 4:12 V, voltage level 5:14 V) is applied for a predetermined time (300 μs) for 14 seconds.

  By the cleansing mode, a potential difference is generated between the skin and the two electrodes, and dirt on the skin can be raised.

Moisturizing mode In the moisturizing mode, the first RF output, the ion and EMS outputs, and the second RF output are sequentially repeated. The operation time in the moisturizing mode is 5 minutes for the normal course and 3 minutes for the time reduction course (FIG. 5).

  In the first RF output in the moisturizing mode, a repetition of a 3 second RF application period in which an RF voltage (2 MHz; 120 V) is applied between the first electrode 100 and the second electrode 200 and a 1 second pause period. Perform for 16 seconds.

  In the moisturizing mode, a potential difference is generated between the skin and both electrodes, so that the serum can permeate the skin.

Shape mode In the shape mode, the RF output and the EMS output are alternately repeated. The operation time in the shape mode is 5 minutes in the normal course and 3 minutes in the time reduction course (FIG. 5).

  In the RF output in the shape mode, an RF voltage (100 kHz; 130 V) is applied between the first electrode 100 and the second electrode 200 for 14 seconds.

  In the EMS output in the shape mode, the EMS voltage (10 Hz; voltage level 1:24 V, voltage level 2:36 V, voltage level 2:36 V, voltage level) is applied between the first electrode 100 and the second electrode 101 every time a predetermined time (100 ms) elapses. A voltage of 3:48 V, a voltage level of 4:60 V, and a voltage level of 5:78 V) is applied for a predetermined time (200 μs) for 6 seconds.

  In the shape mode, the low frequency of the EMS acts on the facial muscles of the face, moves the muscles to promote fat burning, and the heat of the RF waves further enhances the effect.

Lift Mode The lift mode is a mode in which the RF voltage (2 MHz; 120 V) is applied between the first electrode 100 and the second electrode 101 to repeat a 2-second RF application period and a 1-second pause period. In the mode, the skin is irradiated with light having a wavelength of about 630 nm from the red LED. The operation time in the lift mode is 5 minutes in the normal course and 2 minutes in the time reduction course (FIG. 5).

  In the lift mode, metabolism is promoted by the heat effect of RF and the cell activation effect of red light of the red LED. The red light of the red LED occupies the longest wavelength region in the visible light, and the longer the wavelength, the deeper the light acts on the skin.

Cooling mode In the cooling mode, the temperature of both electrodes is reduced by an endothermic reaction of the Peltier element. As a result, the temperature of the skin that has generated heat by the operation of the various modes can be reduced. The operation time in the cooling mode is 3 minutes in the normal course and 2 minutes in the shortened course (FIG. 5).

  During each mode, the skin may be illuminated with light of a particular wavelength from light source 90. For example, a wavelength of about 630 nm can activate skin cells to improve skin troubles (fine lines, dullness, bears under eyes, firmness, texture, acne). Further, when the wavelength is about 410 nm, it is possible to suppress rough skin and sterilize acne bacteria. If the wavelength is about 830 nm, an anti-aging effect can be exhibited.
