FIG. 2 is a perspective view of a portion of the beauty instrument of the first embodiment as seen from the head portion side. FIG. 3 is a plan view of part of the beauty instrument of the first embodiment as seen from the rear side. FIG. 4 is a plan view showing the electrode shape of the head portion of the beauty instrument of the first embodiment.

As shown in FIG. 1, the beauty instrument 1A(1) includes a body portion 10 held by a user, and a head portion 30A(30) capable of supplying electric currents with different characteristics to the user's skin. The beauty instrument 1A is used by the user holding the body portion 10 and bringing the head portion 30A into contact with the user's skin during treatment.

(main body)
As shown in FIG. 1, the main body portion 10 has a longitudinal direction that connects the bottom portion 11 and the top portion 16 on which the head portion 30A is provided. It is a columnar housing having a back portion 14 . The height of the top portion 16 on which the head portion 30 is provided is lower on the side of the front portion 12 than on the side of the back portion 14, so that when the user grips the body portion 10 during treatment, the head portion 30A can be held by the user. It is easy to make contact with the skin of.

Here, the front portion 12 is a portion that faces the user when the user grips the body portion 10 during treatment. Also, the back portion 14 is a portion on the back side of the front portion 12 . When the user grips the main body 10 during treatment, the user's fingers other than the palm and thumb usually come into contact with the back surface 14 , and the user's thumb tends to come into contact with the front surface 12 .

The front portion 12 is provided with a power/mode switch 18 for turning on/off the power, switching between usage modes, and the like, and a level switch 17 for adjusting the power supply level. Modes of use, which will be described in detail later, include, for example, wave lift mode, RF treatment mode, moisturizing mode, and eye care mode. These modes are set based on the frequency of current applied to the user's skin, the combination of currents applied, and the like.

Each use mode is set by combining, for example, application of voltage between electrodes of one or more types of output voltages of a first output, a second output, and a third output with different frequencies, which will be described later, and LED light irradiation. be done. Specifically, in the wave lift mode, for example, the voltage of the second output is applied to the front stage of the unit time, and the voltage of the first output is applied to the rear stage between the electrodes, and the LED light irradiation is performed for all within the unit time. set to In this way, when voltages with different frequencies are applied in different time zones within a unit time, voltages with different frequencies can be applied to the same electrode 50 . Therefore, when voltages with different frequencies are applied in different time zones within a unit time, it is possible to reduce the number of the plurality of electrodes 50 provided in the head section 30A, thereby downsizing the head section 30A. become.

The current applied to the user's skin is generated by applying currents having different characteristics to the parallel electrode group 40, which is an aggregate of three or more electrodes 50 arranged in parallel on the head portion 30A. The parallel electrode group 40 includes, for example, a first output having a first frequency, a second output having a second frequency lower than the first frequency, and a third output lower than the first frequency, which will be described later. A voltage is applied, such as a third output having a frequency of . Here, the first output, the second output, and the third output will be briefly described, but the details will be described later.

The first output is a high-frequency current output, which is the main output with a high output time ratio in, for example, the RF treatment mode. As will be described later, the RF treatment mode is mainly a mode in which Joule heat is generated inside the skin by applying a high-frequency current to the skin. The RF treatment mode mainly promotes the production of collagen in the skin and increases the blood flow in the capillaries by the generated Joule heat, and the user can improve skin lift-up and skin dullness. This mode is for the purpose of obtaining an effect.

In addition, the output time ratio is the time of each output when one cycle of the output in the use mode sequentially performs one or more outputs selected from the first output, the second output, and the third output. Means output ratio. For example, if one cycle of output in RF treatment mode is first output 208 ms, blank (non-output) 5 ms, third output 32 ms, blank (non-output) 5 ms, the output time ratio of the first output is 208/250.

The second output is a relatively low frequency current output, such as the output used in wavelift mode. As will be described later, the wave lift mode is a mode that mainly aims to obtain the effect of tightening the skin by applying the electric current to the user's skin and vibrating the facial muscles with electrical stimulation. be.

The third output is a medium-frequency current output, and is an output with a high output time ratio in the moisturizing mode and the eye care mode, for example. As will be described later, the purpose of the moisturizing mode is to increase the cosmetic effect of the cosmetic ingredients by passing the electric current through the user's skin to allow the cosmetic ingredients to penetrate deep into the stratum corneum. mode. In the eye care mode, the electric current is applied to the skin around the eyes of the user, and the beauty ingredients for the eye area are deeply penetrated into the stratum corneum, thereby enhancing the beauty effect of the beauty ingredients and providing a warm sensation to the eyes. It is a mode that aims to obtain the action to give.

Wavelift mode is set, for example, to use a combination of the second output, the first output, and LED light illumination as described below. The RF treatment mode is set, for example, to use a combination of the first output, the third output, and LED light illumination. The moisturizing mode, for example, is set to use a combination of the third output, the first output, and LED light illumination at a different output time ratio than the RF treatment mode. The eye care mode, for example, is set to use a combination of the third output, the first output, and LED light illumination at different output time ratios than the RF treatment mode and the moisturizing mode. The LED light irradiation amount in the eye care mode is, for example, less than the LED light irradiation amount in the moisturizing mode.

The third output is the one or more electrodes 50 provided on the head portion 30A and the one or more electrodes 50 (body electrodes 20) provided on the body portion 10 held by the user. A user's skin is energized by applying a voltage between them.

That is, the body electrode 20 can be a body electrode 20 composed of one or more electrodes 50 .

The body electrode 20 is electrically conductive with the electrode 50 provided on the head portion 30A. Specifically, an output voltage such as a third output is applied between at least some of the electrodes forming the parallel electrode group 40 of the head portion 30A and the body electrodes 20 of the body portion 10. there is

Specifically, among the electrodes constituting the parallel electrode group 40, all the electrodes to which the voltage of the third output is applied have the same polarity, and among the electrodes constituting the parallel electrode group 40, the voltage of the third output It is preferable that the voltage is applied so that the electrode to which is applied and the body electrode 20 have different polarities. When the voltage of the third output is applied between the parallel electrode group 40 and the main body electrode 20 in this way, the iontophoresis efficiency of the cosmetic component is high, which is preferable.

The head section 30A has a plurality of electrodes 50 on the head section surface 32, and currents with different characteristics can be passed through the electrodes 50 to the user's skin.

As shown in FIG. 1, the head section 30A has a parallel electrode group 40 that is an aggregate of three or more electrodes 50 arranged in parallel. Moreover, as shown in FIG. 2, between the adjacent electrodes 50, 50 among the four electrodes 61 (50), 75A (50), 75B (50), 69 (50) that constitute the parallel electrode group 40, A plurality of LED lights 35 are provided on the head surface 32 .

For example, a red LED light is used as the LED light 35 . By irradiating the skin with red LED light, it is possible, for example, to promote repair of skin cells and blood circulation, and to soothe inflammation and redness of the skin. The LED light 35 can be lit in conjunction with a use mode such as a wave lift mode, for example.

The second output is a relatively low-frequency current output having a second frequency, and is normally a current output at a frequency used for EMS (Electrical Muscle Stimulation). As the second frequency, for example, a frequency within the range of 1 Hz to 10 kHz, preferably 5 Hz to 2.5 kHz is used. The second output has the effect of, for example, applying the electric current to the user's skin to vibrate the muscles of facial expression by electrical stimulation, thereby obtaining tightened skin. The second output is used, for example, in wave lift mode, with the first output and at a lower output time ratio than the first output.

The second output is that when a voltage is applied between a pair of relatively distant electrodes 50, 50 among the electrodes 50 constituting the parallel electrode group 40, facial muscles are vibrated by electrical stimulation to tighten them. It is preferable because the effect of obtaining smooth skin tends to increase. This is because it is presumed that the greater the distance between the electrodes 50 to which the voltage of the second output is applied, the more deep and wider facial muscles can be vibrated by electrical stimulation.

The third output is a medium frequency current output having a third frequency lower than the first frequency, and is typically a frequency current output used for IP (Iontophoresis). As the third frequency, for example, a frequency within the range of 1 kHz to 10 kHz, preferably 1 kHz to 2 kHz is used. The third output, for example, has the effect of increasing the cosmetic effect of the cosmetic ingredients by passing the electric current through the user's skin to allow the cosmetic ingredients to penetrate deep into the stratum corneum. The third output is used, for example, in moisturizing mode and eye care mode, in conjunction with the first output and at the same rate of output time as the first output.

The third output is preferable because when a voltage is applied between each electrode 50 constituting the parallel electrode group 40 and the main body electrode 20, the efficiency of iontophoresis of cosmetic ingredients is high.

The first output, the second output, and the third output are voltages applied between specific combinations of the electrodes 50 and the body electrodes 20 (50) constituting the parallel electrode group 40. is preferred.

For example, the first output and the second output are alternately output in different time zones. Alternating outputs in different time periods are preferable because a voltage can be applied to the same electrode, so that the number of electrodes 50 can be reduced and the size of the head section 30 can be reduced. It should be noted that if the application time of the first output is longer than that of the second output, the effect of warming the skin by the first output is prolonged, and wrinkles and sagging of the skin are likely to be reduced, which is preferable.
