Patent No. 6445212

When outputting an RF signal, if the distance between the electrodes to which the voltage is applied is increased, the skin does not warm up easily, so it is preferable to shorten the distance between the electrodes. On the other hand, when outputting an EMS signal, if the distance between the electrodes to which the voltage is applied is shortened, the user will experience an uncomfortable tingling sensation.

The aim of the present invention is to achieve both skin warming and muscle stimulation without causing discomfort.

The present invention provides a beauty device comprising: a first electrode having an outer periphery that is a circle, an ellipse or a triangle; three second electrodes that are positioned around the first electrode, the distance to the first electrode being within a predetermined first range and the distance to each of the adjacent electrodes being within a predetermined second range; and an output section that outputs a first signal using the first electrode and at least one of the second electrodes, and outputs a second signal having a frequency different from that of the first signal using the multiple second electrodes.

In the present invention, the distance from the first electrode to the second electrode may be shorter than the distance between adjacent second electrodes.

In the present invention, the frequency of the second signal may be lower than the frequency of the first signal.

In the present invention, an end face of the second electrode facing an end face of another adjacent second electrode may be configured to be parallel to the end face of the other second electrode.

In the present invention, the output section may be configured to change the set of second electrodes to which the second signal is output at a predetermined timing.

In the present invention, the output section may be configured to switch the set of second electrodes to which the second signal is output each time the output section outputs the second signal.

In the present invention, a surface of the second electrode may protrude beyond a surface of the first electrode.

In the present invention, the second electrode may be configured to have an arc shape that protrudes in a direction opposite to a direction of the first electrode.

[Embodiment]
(Configuration of the embodiment)
FIG. 1 is a perspective view of a beauty device 1 according to an embodiment of the present invention. FIG. 2 is a front view of the beauty device 1.
Fig. 3 is a top view of the beauty device 1, and Fig. 4 is a side view of the beauty device 1. The beauty device 1 is a device that outputs an electrical signal to the face to heat the facial skin and contract the facial muscles. In this embodiment, the beauty device 1 is capable of outputting an RF electrical signal and an electrical signal for EMS.

The beauty device 1 has a main body 10 and a head 20. The main body 10 has a plurality of buttons 31 for operating the beauty device 1, and a plurality of LEDs 32. The main body 10 is an example of a gripped part according to the present invention. In the beauty device 1, the power can be turned on/off, the signal to be output can be switched, and the like, by operating the button 31. The LEDs 32 are light-emitting diodes. The strength of the electrical signal to be output is indicated to the user by the number of lit LEDs 32.
The main body 10 also includes a power source for powering the beauty device 1, an electric circuit for generating an electric signal to be output to the body, and a control unit for controlling the output electric signal. The power source is, for example, a secondary battery, but may also be a primary battery or a household AC power source.

The head 20 has a first electrode 21, a second electrode 22A, a second electrode 22B, a second electrode 22C, an insulating portion 23, and a hemispherical electrode 40A and a hemispherical electrode 40B. The first electrode 21 is an example of a first electrode according to the present invention, and the second electrodes 22A, 22B, and 22C are an example of a second electrode according to the present invention. The head 20 freely rotates in a stepless manner relative to the main body 10. The head 20 is an example of a rotating portion according to the present invention.

The insulating portion 23 has a flat surface and is made of an insulating material. The insulating portion 23 is disposed between the first electrode 21 and the second electrode 22A, between the first electrode 21 and the second electrode 22B, and between the first electrode 21 and the second electrode 22C.
2C, between the second electrode 22A and the second electrode 22B, between the second electrode 22B and the second electrode 22C
and between the second electrode 22C and the second electrode 22A. The surface of the insulating portion 23 is inclined with respect to the main body 10. For example, when a plane is imagined that includes the vertical center line of the main body 10 and extends left and right when viewed from the front, the angle θ between this imagined plane and the surface of the insulating portion 23 is 10 degrees. Furthermore, when the center line of the insulating portion 23 is imagined to be perpendicular to the surface of the insulating portion 23, this center line is not parallel to the rotation axis of the head 20, and is insulated from the rotation axis of the head 20.
The center line is inclined with respect to the rotation axis of the head 20. The inclination angle of this center line with respect to the rotation axis of the head 20 is also 10 degrees. Note that these angles are not limited to 10 degrees and may be angles other than 10 degrees.

The first electrode 21 is made of a conductive material and is used when outputting an RF electrical signal to the body. In this embodiment, the first electrode 21 has a ring shape with a circular outer edge and is disposed in the center of the head 20. The surface of the first electrode 21 is parallel to the surface of the insulating portion 23. In this embodiment, the diameter B of the first electrode 21 is
It is preferable that the distance between the first electrode 21 and the electrode 22 is within a range of 10 mm to 30 mm. The shape of the first electrode 21 is not limited to a circular ring shape, and may be a disk shape.

The second electrodes 22A, 22B, and 22C are made of a conductive material and are used when outputting an RF electrical signal to the body and when outputting an EMS electrical signal to the body. Since the second electrodes 22A, 22B, and 22C have the same configuration, they will be referred to as the second electrodes 22 in the following description unless it is necessary to distinguish between them.

In this embodiment, the second electrode 22 has an arc shape that protrudes in the opposite direction to the first electrode 21, is concentric with the first electrode 21, and is disposed outside the outer periphery of the first electrode 21 when viewed from the front. The second electrodes 22A, 22B, and 22C have the same circumferential length of the arc shape. The surface of the second electrode 22 is parallel to the surface of the insulating portion 23. In this embodiment, it is preferable that the diameter A of a circle connecting the outer peripheries of the second electrodes 22A, 22B, and 22C is within the range of 20 mm to 50 mm.

The hemispherical electrodes 40A and 40B are disposed outside the outer periphery of the insulating portion 23 in the head 20. The hemispherical electrodes 40A and 40B are formed of a conductive material and have the shape of a protrusion with a semicircular tip. The hemispherical electrodes 40A and 40B are an example of the protrusion according to the present invention.
Hemispherical electrode 40A and hemispherical electrode 40B are electrodes used when outputting RF electrical signals to the body and when outputting electrical signals for EMS to the body. Hemispherical electrode 40A and hemispherical electrode 40B are also used when performing finger pressure, for example.

Fig. 5 is a diagram showing the front, top, bottom, right side, and left side of the beauty device 1 when the head 20 is rotated 90 degrees from the state shown in Fig. 2. Fig. 6 is a diagram showing the front, top, bottom, right side, and left side of the beauty device 1 when the head 20 is rotated 180 degrees from the state shown in Fig. 2.

The head 20 is rotatable relative to the main body 10, and if one imagines the center line of the insulating part 23 to be perpendicular to the surface of the insulating part 23, this center line is not parallel to the rotation axis of the head 20, but is inclined relative to the rotation axis of the head 20. Therefore, by rotating the head 20, the surface of the first electrode 21 and the surface of the second electrode 22 can be brought into contact with the body at various angles.

For example, the state shown in FIG. 1 to FIG. 4 is defined as a state in which the rotation angle of the head 20 is 0 degrees.
When the rotation angle is 0 degrees, the surface of the insulating portion 23, the surface of the first electrode 21, and the surface of the second electrode 22 face upward as shown in Figure 4 when viewed from the side, so that when the main body 10 is gripped, the surfaces of the first electrode 21 and the second electrode can be easily placed against the face line.

5, when the rotation angle is 90 degrees, the surface of the insulating portion 23, the surface of the first electrode 21, and the surface of the second electrode 22 face left when viewed from the front, so that when the main body 10 is grasped and the surfaces of the first electrode 21 and the second electrode 22 are placed against the face, the first electrode 21 and the second electrode 22 can be easily placed against the right half of the face. Although not shown, when the rotation angle is 270 degrees, the surface of the insulating portion 23, the surface of the first electrode 21, and the surface of the second electrode 22 face right when viewed from the front, so that when the main body 10 is grasped and the surfaces of the first electrode 21 and the second electrode 22 are placed against the face, the first electrode 21 can be easily placed against the left half of the face.
This also makes it easier to apply the second electrode.

6, when the rotation angle is 180 degrees, the surface of the insulating part 23, the surface of the first electrode 21, and the surface of the second electrode 22 face downward when viewed from the side, so that the surfaces of the first electrode 21 and the second electrode 22 can be easily applied to the nose when the main body 10 is gripped. In addition, since the hemispherical electrodes 40A and 40B are located at the ends of the cosmetic device 1 in the longitudinal direction, the hemispherical electrodes 40A and 40B can be easily applied to, for example, the corners of the eyes or around the nostrils.

7 is an enlarged view of the head 20. A distance D11 from the outer periphery of the first electrode 21 to the inner periphery of the second electrode 22A, a distance D12 from the outer periphery of the first electrode 21 to the inner periphery of the second electrode 22B,
and the distance D13 from the outer periphery of the first electrode 21 to the inner periphery of the second electrode 22C are the same (distance D11 = distance D12 = distance D13). Regarding the distances between adjacent second electrodes 22, the distance D21 between the second electrode 22A and the second electrode 22B, the distance D22 between the second electrode 22B and the second electrode 22C, and the distance D23 between the second electrode 22C and the second electrode 22A are the same (distance D21 = distance D22 = distance D23). Also, the distance D21 is longer than the distance D11. That is, the distance between adjacent second electrodes 22 is
The distance D11 is longer than the distance between the electrode 21 and the second electrode 22. For example, the distance D11,
The distances D12 and D13 are 3 mm, and the distances D21, D22 and D2
In addition, if the relationship of distance D21, distance D22, distance D23>distance D11, distance D12, distance D13 is satisfied, for example, distance D11, distance D12, and distance D13 are within the range of 1 mm to 10 mm, and distance D21, distance D22, and distance D2 are within the range of 1 mm to 10 mm.
3 may be within a range of 5 mm to 20 mm. In addition, the height from the flat surface of the insulating portion 23 to the upper surface of the second electrode 22 is higher than the height from the surface of the insulating portion 23 to the upper surface of the first electrode 21. For example, the height from the surface of the insulating portion 23 to the upper surface of the second electrode 22 is 1.
6 mm, and the height from the surface of the insulating portion 23 to the upper surface of the first electrode 21 is 1 mm. The difference in height between the first electrode 21 and the second electrode 22 is preferably within a range of 0 mm to 2 mm. Note that the distances D11, D12, and D13 do not have to be the same distance, but may be within a predetermined range. Also, the distances D21, D22, and D23 do not have to be the same distance, but may be within a predetermined range.

In this embodiment, the end face of the second electrode 22 that faces the end face of the adjacent other second electrode 22 is parallel to the end face of the other second electrode 22. Specifically, the end face of the second electrode 21A on the second electrode 21B side is parallel to the end face of the second electrode 21B on the second electrode 21A side.
The end face of the second electrode 21C is parallel to the end face of the second electrode 21B in the circumferential direction of the second electrode 21C.
The circumferential end face of the electrode 21A is parallel to the end face on the second electrode 21C side.

8 is a block diagram of the beauty device 1. The output unit 102 outputs a first RF electrical signal.
The output unit 102 has an electric circuit that outputs a first signal having a frequency lower than that of the first signal and a second signal having a second frequency that is an electric signal for the EMS and is lower than that of the first signal. The output unit 102 is an example of an output unit according to the present invention. The output unit 102 is controlled by the control unit 101 and outputs the first signal or the second signal.
When outputting a first signal, the output unit 102 outputs the first signal to the skin using a pair of the second electrode 22 and the first electrode 21 or a pair of the hemispherical electrode 40A and the hemispherical electrode 40B. When outputting a second signal, the output unit 102 outputs the first signal to the skin using a pair of the second electrode 22A and the second electrode 22B, or a pair of the second electrode 22B.
and second electrode 22C, the pair of second electrodes 22C and 22A, or the pair of hemispherical electrodes 40A and 40B outputs a second signal.

The control unit 101 is, for example, a microcomputer that operates according to a stored program. The control unit 101 controls the output unit 102 to turn on/off the output of an electrical signal to the body.
It controls whether the switch is turned off or the type of electrical signal to be output.

For example, when a predetermined operation is performed on the button 31, the control unit 101
The control unit 101 controls the output unit 102 so that the first signal and the second signal are output alternately. Specifically, the control unit 101 first outputs the first signal so that a current flows through the body between the second electrodes 22A, 22B, and 22C and the first electrode 21. When the first electrode 21 and the second electrode 22 are in contact with the skin of the face, the skin is warmed by the output first signal, and the metabolism of the warmed area is improved. In this embodiment, the frequency of the first signal is 1 MHz to 3
Although the frequency is in the range of MHz, it is not limited to this range and other frequencies may be used as long as they have the effect of warming the skin.

When a predetermined time has elapsed since the control unit 101 started outputting the first signal, the control unit 101 stops outputting the first signal and outputs a second signal so that a current flows through the body between the pair of electrodes, that is, the pair of second electrodes 22A and 22B, the pair of second electrodes 22B and 22C, or the pair of second electrodes 22C and 22A. The predetermined time during which the first signal is output is 40 ms in this embodiment, but is not limited to 40 ms and may be other times. When the first electrode 21 and the second electrode 22 are in contact with the skin of the face, the output second signal contracts the facial mimetic muscles, improving the tension and elasticity of the skin. In this embodiment, the frequency of the second signal is in the range of 70 kHz to 110 kHz, but is not limited to this range and may be other frequencies as long as they have the effect of contracting the muscles.

When a predetermined time has elapsed since the start of output of the second signal, the control unit 101 stops output of the second signal and outputs the first signal so that a current flows through the body between the second electrodes 22A, 22B, and 22C and the first electrode 21. In this embodiment, the predetermined time during which the second signal is output is 25 ms.
After that, the control unit 101 repeats the above-mentioned operation to alternately output the first signal and the second signal, and first
When a predetermined time has elapsed since the start of outputting the signal, the output of the electrical signal is stopped. Note that, although the output period of the first signal and the output period of the second signal are the same in this embodiment, the output period of the first signal and the output period of the second signal may be different.

In addition, when an operation is performed to output the first signal and the second signal from hemispherical electrode 40A and hemispherical electrode 40B, the control unit 101 controls the output unit 102 so that the first signal and the second signal are output alternately from the pair of hemispherical electrode 40A and hemispherical electrode 40B.

According to this embodiment, when the first signal is output, the distance between the first electrode 21 and the second electrode 22 for outputting the first signal is a distance suitable for warming the skin (distance D11, distance D12
, distance D13), the skin is not difficult to heat.
Regarding the second signal, the greater the distance between the output electrodes, the greater the muscle movement, and the greater the area of the output electrodes in contact with the skin, the lower the output per unit area, and the less stimulation to the muscle. In this embodiment, when the second signal is output, the distance between the two second electrodes 22 that output the second signal is the distance (distance D21, distance D22, distance D23) and area suitable for outputting the second signal, so that discomfort to the skin can be suppressed when the second signal is output.

FIG. 9 shows four second electrodes 22D, 22E, 22F and 22C.
9 is a diagram showing a part of the head 20A having the insulating portion 23 and the first electrode 21. In the case of the configuration shown in Fig. 9, the diameter of the insulating portion 23 and the diameter of the first electrode 21 are the same as the diameters of the insulating portion 23 and the first electrode 21 shown in Fig. 7. In this case, when the distances from the first electrode 21 to the second electrodes 22D, 22E, 22F, and 22G are the same as the distance D11, the second electrodes 22D,
The surface area of each of the second electrodes 22E, 22F, and 22G is smaller than the surface area of each of the second electrodes 22A, 22B, and 22C, and the output per unit area increases, which may cause more stimulation to the muscles and cause discomfort. In this embodiment, the number of second electrodes 22 is three, and compared to the configuration shown in FIG. 9, the number of second electrodes 22A is three.
Since the surface area of each of second electrodes 22B and 22C can be increased, the output per unit area is reduced, the stimulation to the muscles is reduced, and discomfort can be suppressed.

In the configuration shown in Fig. 9, when a second signal is output from a pair of adjacent second electrodes 22, the directions in which the second signal flows are the up-down direction and the left-right direction in Fig. 9. On the other hand, in this embodiment, there are three directions, namely, from second electrode 22A to second electrode 22B, from second electrode 22B to second electrode 22C, and from second electrode 22C to second electrode 22A, and it is possible to stimulate muscles in more directions than in the configuration shown in Fig. 9.

According to the present embodiment, the first signal is output for a period of 40 ms, and then the second signal is output for a period of 25
By repeating the output of the second output for a period of 100 ms, the warming of the skin and muscle contraction are repeated in a short cycle, and muscle contraction can be performed while maintaining a sense of warmth.
Since the set of second electrodes 22 that output the signal is switched, the position on which the second signal acts changes every time the set of second electrodes 22 that output the second signal is switched, even if the head 20 is not moved.
Compared with a configuration in which the set of second electrodes 22 that outputs the second signal is not switched, a bodily sensation similar to tapping can be obtained, and the muscles can be stimulated more. The period for outputting the first signal may be set to 250 ms, and the period for outputting the second signal may be set to 250 ms. With such an output, the user of the beauty device 1 can experience a bodily sensation as if the skin is being sucked when the second signal is output.

Next, the results of the sensory evaluation performed by changing the dimensions of the first electrode 21 and the second electrode 22 will be described with reference to Figs. 10 to 12. In the sensory evaluation, the head 2 of types 1, 3, 5, and 7 was used.
10. For each of types 1, 3, 5, and 7, the dimensions of the first electrode 21 and the second electrode 22 are as shown in FIG.
It shows the area of the electrode 22. Furthermore, the area ratio shows the ratio of the area of one second electrode 22 to the area of a circle with diameter A.

Fig. 11 shows the results of evaluations by four subjects comparing the sensation of EMS due to differences in electrode area for types 1, 3, and 5 in which the height of the first electrode 21 and the second electrode 22 is different, and type 7 in which the height of the first electrode 21 and the second electrode 22 is the same.
The results show the results of an evaluation of the EMS experience for types 1 and 5, divided into five levels, with 1 being painful and unusable, 2 being tolerable pain but bad, 3 being neither good nor bad, 4 being generally good, and 5 being good with no room for improvement.

In comparing Type 1 and Type 3, the EMS sensation was evaluated as being less tingly with Type 3, which has a larger electrode area, but the sensation when placed on the face was evaluated as being better with Type 1, which has a smaller diameter A.
It is preferable that all of the first electrode 2A, the second electrode 22B, and the second electrode 22C have a diameter A that contacts the face. In addition, when focusing on the ratio of the area of one second electrode 22 to the area of the circle with diameter A, Type 1, which has a larger area ratio, is evaluated as being better, and for EMS to the face,
It can be seen that it is preferable for the area of the second electrode 22 in the head 20 to be large.

In a comparison between types 1 and 5, type 1, which has a larger area of the second electrode 2, was rated higher in terms of physical sensation than type 5, and in a comparison between types 1 and 7, type 1, which has a larger area of the second electrode 2, was rated higher in terms of physical sensation than type 7. Also, in terms of the ratio of the area of one second electrode 22 to the area of a circle of diameter A, type 1, which has a larger area ratio than types 5 and 7, was rated higher than types 5 and 7.
are the same, it is preferable to increase the area of the second electrode 22 and increase the area of the second electrode 22 in the head 20. In the present invention, it is preferable that at least the ratio of the area of one second electrode 22 to the area of a circle with diameter A is a value exceeding the value of Type 5. More preferably, it is a value equal to or greater than 0.155, which is the value of Type 1.

[Modification]
Although the embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and can be embodied in various other forms. For example, the above-mentioned embodiment may be modified as follows to implement the present invention. The above-mentioned embodiment and the following modifications may be combined with each other.

In the present invention, when the first signal and the second signal are output alternately, the second electrode 22 used when outputting the first signal may be changed every time the timing of outputting the first signal is reached. For example, the control unit 101 may output the first signal and the second signal from a pair of the first electrode 21 and the second electrode 22A, output the first signal and the second signal from a pair of the first electrode 21 and the second electrode 22B,
The first signal may be output in the order of outputting a signal from the pair of first electrode 21 and second electrode 22C, outputting the first signal from the pair of first electrode 21 and second electrode 22C, and this output order may be repeated. Also, during the period in which the first signal is output, the second electrode 22 paired with the first electrode 21 may be changed every time a predetermined time elapses.

In the present invention, when the first signal and the second signal are output alternately, the set of second electrodes 22 that outputs the second signal may be changed every time the timing of outputting the second signal is reached. For example, the control unit 101 may output the first signal, output the second signal with the set of the second electrodes 22A and 22B, output the first signal, output the second signal with the set of the second electrodes 22B and 22C, output the first signal, output the second signal with the set of the second electrodes 22C and 22A, and repeat this output order. Also, during the period in which the second signal is output, the set of second electrodes 22 that outputs the second signal may be changed every time a predetermined time elapses. Note that, in a configuration in which the set of the second electrodes 22 that outputs the second signal is changed every time the timing of outputting the second signal is reached, the second electrodes 22 used when outputting the first signal may be changed every time the timing of outputting the first signal is reached.

The third electrode 24 is made of a conductive material and is used when outputting the first signal to the body. The third electrode 24 is formed in a ring-shaped ellipse with an elliptical outer edge and is disposed in the center of the head 20. The fourth electrode 25A and the fourth electrode 25B are made of a conductive material and are used when outputting the first signal and the second signal. The fourth electrode 25A and the fourth electrode 25B are formed in a shape obtained by cutting out a part of the ring-shaped ellipse and are convex in the opposite direction to the third electrode 24, and are disposed concentrically with the third electrode 24 and outside the outer periphery of the third electrode 24 when viewed from the front.

The distance D14 from the outer periphery of the third electrode 24 to the inner periphery of the fourth electrode 25A and the distance D15 from the outer periphery of the third electrode 24 to the inner periphery of the fourth electrode 25B are the same distance (D14 = D15). In addition, the circumferential end face of the fourth electrode 25A and the circumferential end face of the fourth electrode 25B are parallel to each other, and the distance D24 between the circumferential end face of the fourth electrode 25A and the circumferential end face of the fourth electrode 25B is longer than the distance D14 (distance D15). In addition, the height from the surface of the insulating portion 23 to the upper surface of the fourth electrode 25A and the fourth electrode 25B is higher than the height from the surface of the insulating portion 23 to the upper surface of the third electrode 24.

The control unit 101 outputs a first signal so that a current flows through the body between the fourth electrode 25A and the third electrode 24 and between the fourth electrode 25A and the fourth electrode 25B.
The second signal is output so that a current flows through the body between the first electrode 25B and the fourth electrode 25B. In this modification, when the first signal is output, the distance between the electrodes for outputting the first signal is set to a distance (D14, D15) suitable for warming the skin, so that the skin is not difficult to heat. Also, when the second signal is output, the distance between the electrodes for outputting the second signal is set to a distance (D14, D15) suitable for warming the skin, so that the skin is not difficult to heat.
The distance between the electrode 25A and the fourth electrode 25B is a distance (D24
) so that discomfort to the skin can be suppressed when the second signal is output.

In the present invention, the first electrode 21 has a circular ring shape, and the second electrode 22 has an arc shape, but may have other shapes.
