Description

  The present invention relates to a beauty instrument used for skin beauty.

  Ion introduction and ion derivation have been proposed as methods for skin beauty. Ion introduction is a technique in which, after a charged cosmetic component is applied to the skin, a weak current having a polarity corresponding to the charge of the cosmetic component is applied to move the cosmetic component toward the inside of the skin. By introducing ions, it is possible to promote penetration of the beauty component into the skin and to make the beauty component act more effectively. In addition, ion derivation is a technique for moving dirt and waste having a charge corresponding to the polarity of the current toward the skin surface by passing a weak current through the skin. By performing ion derivation, dirt, waste, etc. inside the skin can be effectively removed.

  Patent Document 1 discloses a facial device in which a roller is provided at the center of a loop-shaped frame to form a head portion. This facial device is configured such that ions can be introduced and extracted by using a roller as an electrode. Moreover, in addition to the effect by ion introduction and ion derivation, the massage effect by a roller can also be expected.

Japanese Patent No. 5073441

  However, the facial device of Patent Document 1 has a limit in widening the contact area between the roller and the skin because the frame is obstructed when the head portion is in contact with the skin. Therefore, there is a problem that it is difficult to experience the massage effect by the rollers.

  In addition, when the above arrangement is adopted, when a roller is brought into contact with a portion having a relatively undulating shape, such as a face, for example, when the ion introduction or ion derivation is attempted, the beauty tool is strongly pressed against the skin, In some cases, various measures such as making the roller contact while stretching the skin may be necessary. Therefore, there is still room for improvement from the viewpoint of user convenience.

  The present invention has been made in view of such a background, and it is an object of the present invention to provide a beauty instrument that is easy to use and can provide an excellent beauty effect.

One aspect of the present invention includes a main body,
A plurality of support shafts extending from the body;
A rotating body rotatably supported by the plurality of support shafts;
A main electrode provided on the surface of at least one of the plurality of rotating bodies;
A power supply device that supplies power from a power source to the main electrode;
An auxiliary electrode connected to the power supply device;
A control device for controlling the power supplied from the power supply device,
The control device may cause an ion introduction current or an ion derivation current to flow in a closed circuit including the main electrode, the auxiliary electrode, the power feeding device, and the human body in a state where the main electrode and the auxiliary electrode are in contact with the skin. It is in the beauty instrument characterized by being comprised so that it can do.

  The beauty tool includes a main body, a plurality of support shafts extending from the main body, and a rotating body rotatably supported by the plurality of support shafts. In the beauty tool, since the rotating body is disposed outside the main body, the main body is unlikely to interfere when the rotating body is brought into contact with the skin. Therefore, the contact area between the rotating body and the skin can be easily increased, and the massage effect of the rotating body can be more easily experienced.

  In addition, since the rotating body is arranged outside the main body, the main body interferes with the periphery of the raised portion when the rotating body is brought into contact with a portion that has a raised shape, for example, from the surroundings. It becomes difficult to do. As a result, the rotating body can be easily brought into contact with the base of the raised portion, and ion introduction and ion derivation can be easily performed also in such a portion.

  As described above, the beauty tool is easy to use for the user and allows the user to experience an excellent beauty effect.

  In the beauty tool described above, various waveforms such as a direct current in which the current and voltage are constant, a pulse current, and a sinusoidal alternating current can be employed as the waveform of the ion introduction current and the ion derivation current flowing through the skin. For example, when a pulse current is employed, it is preferable to set the wave height as appropriate from the range of 0.05 mA or higher and the frequency as appropriate from the range of 1 to 10 kHz. From the viewpoint of preventing excessive stimulation from being applied to the skin, the upper limit of the pulse height of the pulse current is set to 2.5 mA.

  The power source and the power feeding device may be provided outside the main body, or may be provided inside the main body. In the case where the power source and the power supply device are provided outside the main body, it is possible to reliably supply power for flowing an ion introduction current and an ion derivation current. Further, in this case, since the arrangement space is less limited than in the case where the power source or the like is provided inside the main body, the electrical circuit and the like included in the power feeding device can be freely designed.

  On the other hand, when the power source and the power supply device are provided inside the main body, a cable or the like for supplying power from the power source to the beauty tool is not required, and the usability of the beauty tool can be further improved.

  The auxiliary electrode may be provided on the surface of the main body. In this case, since the configuration of the beauty tool becomes simple, the usability of the beauty tool can be further improved.

  The auxiliary electrode may be provided separately from the main body, and may be connected to the power feeding device via a cable. In this case, it is possible to perform ion introduction or ion derivation even when a practitioner who performs ion introduction or ion desorption on the skin using the beauty instrument is different from a patient who receives ion introduction or ion desorption. it can. A beauty tool having such a configuration can be suitably used, for example, in an esthetic salon.

  The rotating body may have a substantially spherical shape. In this case, since the rotating body in contact with the skin can be smoothly rotated, the operability and the feeling of use of the beauty tool can be improved. In this case, by moving the beauty tool along the skin, the skin is sandwiched between adjacent rotating bodies, and a higher massage effect can be experienced. In the present specification, the substantially spherical shape includes a spherical shape, an elliptical sphere shape, a shape that is generally recognized as a spherical shape and an elliptical sphere shape, or a combination thereof. Some unevenness may be provided on the surface of these shapes.

  It is preferable that the plurality of support shafts are arranged in a direction in which the interval between the support shafts adjacent to each other increases toward the tip. In this case, a state in which the part is sandwiched to some extent between the adjacent rotating bodies can be naturally realized by pressing the rotating body against a portion where the effect such as a massage effect or ion introduction is desired. . Further, in such a state, by moving the beauty tool along the skin, the skin is sandwiched between adjacent rotating bodies, and a higher massage effect can be experienced. In addition, when the beauty tool is moved along the skin, it can effectively remove old keratin and dirt from the skin sandwiched between adjacent rotating bodies. Dirt clogged in pores such as foundations and cosmetics can be effectively removed. In this case, the contact area between the rotating body and the skin can be easily increased. As a result, penetration of cosmetic ingredients into the skin by ion introduction and removal of dirt by ion derivation can be performed more efficiently.

  In addition, in the above state, by using a beauty tool so that the plane including the rotation axis of the adjacent rotating body is inclined with respect to the skin, the skin sandwiched between the adjacent rotating bodies is picked by hand. It can be transformed to raise. As a result, a higher massage effect can be experienced. Further, by deforming the skin so that it is picked up by hand, the skin sandwiched between the rotating bodies is easily stretched. When ion introduction is performed, the contact area between the rotator and the skin is widened by stretching the skin, and the stratum corneum layer on the skin surface is stretched and thinned, so that the penetration of beauty ingredients can be further promoted. . Moreover, when ion derivation is performed, pores are easily opened by stretching the skin, so that dirt and the like inside the skin can be more efficiently removed. As a result, ion introduction and ion derivation can be performed more efficiently, and the effects of ion introduction and ion derivation can be further enhanced.

  The plurality of support shafts are more preferably arranged in a direction closer to the skin toward the tip in a state where the main body is arranged along the skin. In this case, the user can place the rotating body between the main body and the skin by gripping the main body so that the main body is along the skin. Thereby, the convenience of a beauty instrument can be improved more.

  In the above case, it is more preferable that the plurality of support shafts extend radially from the main body. In other words, it is more preferable that the plurality of support shafts extend in a direction that approaches the skin and extends outward from the main body as it goes toward the tip in a state where the main body is disposed along the skin. In this case, when the user grips the main body so that the main body is along the skin, it is possible to easily realize a state in which the plane including the rotation axis of the adjacent rotating body is inclined with respect to the skin. Therefore, the usability of the beauty instrument can be further improved, and the effects of massage effect, ion introduction and ion derivation can be further enhanced.

  The rotating body has a cross-sectional contour line corresponding to the contour in each cutting plane when the rotating body is virtually cut by a plurality of virtual planes perpendicular to the tilt axis inclined with respect to the rotation axis. You may have. In this case, when the rotating body is rotated, the position of the cross-sectional contour line periodically changes according to the rotation, so that it can be easily recognized that the rotating body is rotating.

  The surface of the rotating body is formed in an annular shape and has a plurality of strip surfaces arranged in the axial direction of the tilt axis, and the cross-sectional contour line is visible as a boundary line between adjacent strip surfaces. It may be formed. In this case, it can be easily recognized that the rotating body is rotating due to the effect of the cross-sectional outline. Furthermore, since the plurality of belt-like surfaces are arranged in the axial direction of the tilt axis, the direction of the belt-like surface periodically changes according to the rotation of the rotating body, so that the skin is picked up between the pair of rotating bodies. Strength and weakness will be added to the effect and massage effect. As a result, the massage effect can be further improved, and the user can more easily feel the effect of picking up the skin and the effect of loosening the skin, and an excellent feeling of use can be obtained.

  The band-shaped surface formed in an annular shape may have a shape different from that of the other band-shaped surfaces adjacent to the band-shaped surface so that a boundary line with another band-shaped surface adjacent to the axis direction of the tilt axis can be easily seen. preferable. Specifically, for example, the belt-like surface is configured so that the shape of the belt-like surface in the cross section including the tilt axis and the other belt-like surfaces adjacent thereto are linear, and the inclination angles of the two with respect to the tilt axis are different. can do. In addition, the shape of the belt-like surface in the cross section including the tilt axis is made linear, and the shape of the other belt-like surface adjacent to this is a curved shape swollen outside the rotating body or a curved shape recessed inside the rotating body The belt-like surface can be configured so that In addition, the belt-like surface can be configured such that the shape of the belt-like surface in the cross section including the tilt axis and the other belt-like surface adjacent to the belt-like surface are indented inside the rotating body. In these cases, it is possible to clearly form a boundary line (cross-sectional outline) between the belt-like surface and another belt-like surface adjacent thereto.

  The beauty tool may include two or more main electrodes, and the control device may be configured to individually control the potentials of the plurality of main electrodes. In this case, the beauty tool can form a closed circuit including at least two main electrodes, a power feeding device, and skin. Then, by applying a pulse current or the like to the closed circuit, electrical stimulation can be given to the contact portion of the skin with the main electrode and the vicinity thereof. As a result, it can be expected that a cosmetic effect such as promoting blood circulation of the skin is obtained.

  As shown in FIG. 2, the axial distance between the pair of support shafts 13 and 14 (the distance between the ends of the support shafts 13 and 14 opposite to the main body 12) and the axial distance between the support shafts 15 and 16. Are configured to have the same L1. Further, the support shafts 13 and 15 and the support shafts 14 and 16 between the pairs are also configured such that the axial distance L2 thereof is the same. The axis interval L2 between the pair of support shafts 13 and 15 and the support shafts 14 and 16 is configured to be larger than the axis interval L1 between the pair of support shafts 13 and 14 and the support shafts 15 and 16. .

  As shown in FIG. 8, the angle α formed by the axis 131 of the support shaft 13 and the axis 141 of the support shaft 14 in a cross section parallel to the support shaft 13 and the support shaft 14 is preferably 60 ° to 80 °, and 70 More preferably. Although not shown, in the cross section parallel to the support shaft 15 and the support shaft 16, the angle formed by the axis 151 of the support shaft 15 and the axis 161 of the support shaft 16 is the same as the angle α formed by the axis 131 and the axis 141. is there. Further, as shown in FIG. 7, when viewed from the direction in which the center of the rotator 17 and the center of the rotator 18 overlap, the virtual line T and the support shaft perpendicular to the plane U with which all of the rotators 17 to 20 are in contact. The angles β formed by the axes 131 and 141 of 13 and 14 are 30 °, respectively. In addition, when viewed from the direction in which the center of the rotating body 19 and the center of the rotating body 20 overlap, the angles γ formed by the virtual line T and the axes 151 and 161 of the support shafts 15 and 16 are 30 °.

  The rotating body 17 is larger than the distance M1 between the outer surface (main electrode 170) of the rotating body 17 and the outer surface (main electrode 180) of the rotating body 18 (that is, the distance between the rotating body 17 and the rotating body 18) shown in FIG. The distance M2 between the outer surface (main electrode 170) and the outer surface (main electrode 190) of the rotating body 19 (ie, the distance between the rotating body 17 and the rotating body 19) is larger. The distance M1 is preferably 9 mm to 13 mm, and more preferably 11 mm. The distance M2 is preferably 14 mm to 40 mm, and more preferably 39.5 mm. In addition, the space | interval of the rotary body 19 and the rotary body 20 is the same as the said distance M1. The interval between the rotating body 18 and the rotating body 20 is the same as the distance M2.

  When the beauty tool 1 of this example is used, if the rotating bodies 17 to 20 are brought into contact with the skin and rotated, the skin and muscles are pressed or picked up by the rotating bodies 17 to 20 and are loosened. In addition, the beauty tool 1 operates the power button 436 so that the power feeding device 33 is operated by the power from the battery 31 mounted in the main body 12, and power is supplied to the main electrodes 170 to 200 via the power feeding device 33. Supplied.

  Furthermore, the beauty tool 1 can change the waveform of the potential difference applied to the main electrodes 170 to 200 by switching the operation mode by operating the switching button 437. Specifically, the beauty tool 1 of this example has three types of operation modes: a positive pulse mode, a negative pulse mode, and an AC pulse mode. The positive pulse mode is an operation mode in which a DC pulse voltage is continuously applied between the four main electrodes 170 to 200 and the auxiliary electrode 126b so that the main electrodes 170 to 200 are at a high potential. The negative pulse mode is an operation mode in which a DC pulse voltage is continuously applied between the four main electrodes 170 to 200 and the auxiliary electrode 126b so that the main electrodes 170 to 200 are at a low potential. The AC pulse mode is a mode in which an AC pulse voltage is continuously applied between the main electrodes 170 and 180 and the main electrodes 190 and 200.

  The positive pulse mode and the negative pulse mode are used when performing ion introduction or ion derivation. Ion introduction is a technique in which, after a charged cosmetic component is applied to the skin, a weak current having a polarity corresponding to the charge of the cosmetic component is applied to move the cosmetic component toward the inside of the skin. For example, in the case where ion introduction of a cosmetic component having a negative charge is performed using the beauty tool 1 of this example, the main electrodes 170 to 200 are brought into contact with the skin to which the beauty component has been applied in advance, and the beauty tool 1 is negatively pulsed. It is sufficient to operate in the mode. By operating the beauty tool 1 in the negative pulse mode, an ion introduction current is generated in the closed circuit including the main electrodes 170 to 200, the auxiliary electrode 126b, the power feeding device 33, and the human body to promote penetration of beauty components into the skin. Can be made.

  Ion derivation is a technique of moving dirt or the like having a charge corresponding to the polarity of the current to the skin surface by passing a weak current through the skin. For example, when removing the negatively charged dirt from the skin using the beauty tool 1 of this example, the main electrodes 170 to 200 are brought into contact with the skin and the beauty tool 1 is operated in the positive pulse mode. You can do it. By operating the beauty tool 1 in the positive pulse mode, it is possible to generate an ion-derived current that moves dirt and the like to the outside of the skin in the closed circuit.

  Further, before the ions are derivatized, uncharged dirt can be removed from the inside of the skin by binding the charged cleaning component to the dirt. For example, a negative charge is imparted to the soil by preliminarily binding the cleaning component having a negative charge to the soil. Thereafter, the main electrodes 170 to 200 are brought into contact with the skin, and the beauty tool 1 is operated in the positive pulse mode, whereby the dirt can be moved to the skin surface as described above.

  The magnitude of the DC pulse voltage applied to the main electrode in the positive pulse mode and the negative pulse mode can be appropriately set so that the weak current flowing in the closed circuit is 0.05 mA or more. By applying a weak current of 0.05 mA or more to the closed circuit, the effects of ion introduction and ion derivation can be sufficiently obtained. The frequency of the DC pulse voltage can be set as appropriate within a range of 1 Hz to 10 kHz.

  The AC pulse mode is used when electrically stimulating the contact portion of the skin with the main electrodes 170 to 200 and the vicinity thereof. That is, by performing the AC pulse mode with the main electrodes 170 to 200 in contact with the skin, a closed circuit including the main electrodes 170 and 180, the skin, the main electrodes 190 and 200, and the power feeding device 33 is obtained. A weak alternating pulse current can be generated, and electrical stimulation can be given to the skin. The potential difference generated between the main electrodes 170 and 180 and the main electrodes 190 and 200 can be appropriately set so that the weak current flowing in the closed circuit becomes 0.1 mA or more. By passing a weak current of 0.1 mA or more through the closed circuit, it is possible to fully experience the electrical stimulation to the skin and to expect a sufficient cosmetic effect.

  In any of the positive pulse mode, the negative pulse mode, and the AC pulse mode, in order to prevent an excessive stimulus from being applied to the skin, the magnitude of the weak current flowing through the skin is set to 2.5 mA or less. It is necessary to control the potential difference.

  These operation modes can be carried out in a state where the beauty tool 1 is stationary. However, by rotating the rotating bodies 17 to 20 while being in contact with the skin, A good cosmetic effect can be expected by the cooperative action of introduction, ion derivation, or electrical stimulation and the above-described kneading and unraveling by rotation of the rotating bodies 17-20.

  At the moment when the rotating bodies 17 to 20 are brought into contact with the skin, the contact portion between the two is very narrow, and the weak current flowing through the skin concentrates on the narrow contact portion, thereby causing excessive electrical stimulation to the user. There is a risk of giving. In order to avoid this, when the rotating bodies 17 to 20 are in contact with the skin, that is, a weak current flows from the main electrodes 170 to 200 to the skin, and a weak current of a predetermined current value or more flows to the skin. When the control device 35 detects it, the potential difference adjustment unit 352 may perform so-called slow start control in which the weak current between the two is gradually increased from a low value.

Next, the control mode for detecting the submerged state in the beauty tool 1 will be described in detail below.
As shown in FIG. 10, first, the power switch 335 is turned on (step S10). Then, the electrical resistance between a pair of submergence detection electrodes 60a and 60b (see FIG. 2) in the submergence sensor 60 is detected (step S11). Then, the submergence detection unit 6 determines whether or not the electrical resistance of the pair of submergence detection electrodes 60a and 60b is equal to or less than a predetermined value (step S12). When the submergence detection unit 6 determines that the electrical resistance is not less than or equal to the predetermined value (No in step S12), the power feeding device 33 is connected to the main electrodes 170 to 200 according to the control instruction of the control device 35 (drive control unit 353). Is supplied (step 13). Then, it returns to step S11.

  In step S12, when the submergence detection unit 6 determines that the electrical resistance is equal to or less than the predetermined value (Yes in step S12), the beauty device 1 is determined to be submerged (step S14). Then, a submergence detection signal is output to the control device 35 (step S15). And the control apparatus 35 judges whether the electric power feeder 33 is supplying electric power to the main electrodes 170-200 (step S16). When it is determined that the power feeding device 33 is not supplying power to the main electrodes 170 to 200 (No in step S16), the process returns to step S11.

  In step S <b> 16, when it is determined that the power feeding device 33 is supplying power to the main electrodes 170 to 200 (Yes in step S <b> 16), the drive control unit 353 of the control device 35 outputs a stop signal to the power feeding device 33. (Step S17). And the electric power feeder 33 stops the electric power supply to the main electrodes 170-200 (step S18). Thereafter, the process returns to step S11. Note that when the control device 35 receives a submergence detection signal from the submergence detection unit 6, the drive control unit 353 outputs a stop signal to the power feeding device 33 without performing the determination process in step S <b> 16. Also good.

  Thereby, when it is determined that the water is submerged, the power supply to the rotating bodies 17 to 20 is controlled to be stopped. As a result, when the main body 12 is submerged, it is possible to reliably prevent an excessive current from flowing between the main electrodes 170 to 200. In FIG. 10, after the process of step S18, the process is returned to step S11. However, after the process of step S18 is completed, the power switch 335 is turned off to end the process shown in FIG. good. In that case, unless the user performs an operation to turn on the power switch 335 again after the power supply from the power supply device 33 to the main electrodes 170 to 200 is stopped due to the output of the submergence detection signal, The power supply from the power feeding device 33 to the main electrodes 170 to 200 is not resumed. Thereby, resumption of the power supply to the main electrodes 170 to 200 not intended by the user can be suitably prevented, and early discharge of the battery 31 is prevented. It is of course possible to configure the power switch 335 to be turned off when the submerged state continues for a certain time (for example, 1 minute). Further, after the power supply from the power supply device 33 to the main electrodes 170 to 200 is stopped, the display on the display unit 52 is notified to the user that the main body 12 is submerged from the display of the operation mode of the power supply device 33. You may make it switch to the display for this. Thereby, it is possible to suitably notify the user that the main body 12 is submerged.

  The beauty tool 1 of the present example has the above configuration, so that when the main body 12 is submerged, the submergence detection unit 6 detects the submergence and outputs a submergence detection signal. Then, when the submergence detection signal is input to the control device 35, the drive control unit 353 controls the voltage applied to the main electrodes 170 to 200 by the power feeding unit 3. Thereby, even if the electrical resistance between the main electrodes 170-200 falls excessively, it can suppress that an electric current flows between the said main electrodes 170-200 excessively. As a result, it is possible to prevent problems such as an electric shock by the user, an excessive load on the electronic components in the beauty instrument 1, and a wasteful consumption of a large amount of power. Therefore, it is not necessary to pay special attention even when used in a place such as a bathroom where there is a risk of being submerged, and it is easy to use.

  In this example, since the submergence detection unit 6 is provided separately from the main electrodes 170 to 200, even when a conductive gel or the like is applied to the skin, Misuse detection is suppressed, and even when the gel is used, it is easy to use.

  The four main electrodes 170 to 200 provided in the beauty tool 1 of this example are formed on the surfaces of the conductive rotating bodies 17 to 20. When using the beauty tool, the user holds the grip part 122 of the main body 12 and presses the rotating bodies 17 to 20 against the skin, for example, as shown in FIGS. ), The beauty tool 1 is moved. At this time, since the preceding pair of rotating bodies 17 and 18 (or the pair of rotating bodies 19 and 20) spread toward the front side in the moving direction, the preceding pair of rotating bodies 17 and 18 (or a pair of rotations). The body 19, 20) rotates inward and the skin is pressed, and a massage effect is produced. On the other hand, since the following pair of rotating bodies 19 and 20 (or the pair of rotating bodies 17 and 18) spread toward the rear side in the moving direction, the following pair of rotating bodies 19 and 20 (or a pair of rotating bodies) The rotating bodies 17 and 18) rotate inward to pick up the skin between the rotating bodies 19 and 20 (or both rotating bodies 17 and 18), and a massage effect is produced. That is, by moving the body 12 in one direction (P1 direction or P2 direction), different massage effects of pressing and picking up the same part of the skin can be obtained.

  Further, even when the beauty tool 1 is moved in the Q1 direction and the Q2 direction, as in the case of the P1 direction and the P2 direction described above, the preceding pair of rotating bodies 17, 19 (or the pair of rotating bodies 18, 20). ) Is rotated inward and the skin is pressed, and the following pair of rotating bodies 18 and 20 (or the pair of rotating bodies 17 and 19) are rotated inward to pick up the skin, and the same part of the skin On the other hand, different massage effects can be obtained by pressing and picking up.

  The axial interval L1 between the rotating bodies 17 and 19 and the rotating bodies 18 and 20 is smaller than the axial interval L2 between the rotating bodies 17 and 18 and the rotating bodies 19 and 20. For this reason, by moving the beauty tool 1 in the P1 direction or the P2 direction, a portion having a large curvature such as an arm or ankle of the body is interposed between the rotating bodies 17 and 18 and between the rotating bodies 19 and 20, respectively. Can be massaged effectively.

  The rotating bodies 17 to 20 are spherical. Thereby, the rotating bodies 17-20 can be smoothly rotated in the state which contacted the skin with the rotating bodies 17-20, and it is excellent in a usability | use_condition. Moreover, the effect of picking up the skin and the effect of relaxing the massage can be achieved, and the massage effect can be further improved. Needless to say, it is possible to make the rotating bodies 17 to 20 oval or a combination of a sphere and an oval.

  Furthermore, at the time of use of this beauty tool 1, it can be deform | transformed so that the skin pinched | interposed between the adjacent rotary bodies 17-20 may be extended according to the said pick-up effect. Therefore, as described above, the effects of ion introduction and ion derivation can be further enhanced. Further, due to the picking effect, the contact area between the skin and the main electrodes 170 to 200 tends to be widened. Therefore, when a weak current is passed from the main electrodes 170 to 200 to the skin, it is possible to make it difficult to cause current concentration in a small area. Therefore, the beauty tool 1 can easily avoid the application of excessive stimulation to the skin due to the weak current, and can improve usability.

  Further, the distance M2 between the rotating bodies 17 and 18 and the rotating bodies 19 and 20 is larger than the distance M1 between the rotating bodies 17 and 19 and the rotating bodies 18 and 20. In the state where the beauty tool 1 is operating in the AC pulse mode, a potential difference is generated between the main electrodes 170 and 180 of the rotating bodies 17 and 18 and the main electrodes 190 and 200 of the rotating bodies 19 and 20 having a large arrangement interval. Is given. For this reason, in the AC pulse mode, a current can flow through a relatively wide range of skins between the main electrodes 170 to 200, so that an appropriate electrical stimulation can be obtained without a current flowing locally. In addition, when the power supply device 33 is operated, the current detection unit 34 and the control device 35 detect the magnitude of the weak current flowing through the skin, and when the detected current value is equal to or greater than a predetermined value, the potential difference adjustment unit 352 As a result, the potential difference from the power feeding device 33 is lowered. For this reason, even when the electrical resistance is small, for example, when the skin is wet, there is no possibility that a strong electrical stimulation is applied due to excessive current flowing through the skin.

  Furthermore, in the AC pulse mode, by applying a conductive gel containing a conductive material to the skin and interposing the conductive gel between the main electrodes 170 to 200 and the skin, the conductivity with respect to the skin is increased. Can do. Thereby, a potential difference can be reliably given between the main electrodes 170 and 180 and the main electrodes 190 and 200, and electrical stimulation can be effectively applied to the skin. In particular, even when the skin is in a dry state, electrical stimulation can be effectively applied to the skin. The kind of electroconductive gel used is not specifically limited, A well-known thing can be used. For example, a conductive gel that exhibits a slimming effect can be used. Thereby, in addition to the said massage effect and electrical stimulation, there exists a slimming effect.

  In this example, the submergence detection unit 6 is provided in the main body 12. Thereby, in the case where the conductive gel is applied to the skin and used, the gel is prevented from interfering with the submergence detection unit 6, so that the erroneous detection of the submerged state by the gel is further suppressed. Therefore, usability when using the gel is further improved.

  In this example, the main body 12 can be gripped, and the submergence detection unit 6 is provided in the main body 12 in the vicinity of the connection part 130 b with the main electrodes 190 and 200. Thereby, it can suppress that a hand touches the submergence detection part 6 when the main body 12 (gripping part 122) is gripped. As a result, it is possible to suppress erroneous detection of the submerged state, and it is possible to reliably detect the submerged state even when the beauty device 1 is submerged while the main body 12 (gripping part 122) is gripped.

  As shown in FIG. 11 (a), the surface of the rotator 17 has cross-sectional contours corresponding to the contours of the respective cross sections by a plurality of virtual planes K perpendicular to the inclined axis 170a inclined with respect to the axis 131 of the support shaft 13. A plurality of lines 171 are formed. A band-shaped surface 172 formed in an annular shape is formed between adjacent cross-sectional contour lines 171. Each band-like surface 172 is gently recessed inside the rotating body 17. Therefore, the belt-like surfaces 172 are arranged in the axial direction of the inclined axis 170a, and the cross-sectional outline 171 is formed so as to be visible as a boundary line between the belt-like surfaces 172 adjacent to each other. In each belt-like surface 172, the width (that is, the length of the inclined axis 170a in the axial direction) is substantially constant.

  The rotating body 17 is rotatable about an axis 131. 11A to 11D, the side projection inclination angle θ of the inclined axis 170a with respect to the axis 131 when viewed from the direction perpendicular to the axis 131 depends on the rotation of the rotating body 17. Observe to change with. As shown in FIGS. 11A and 11C, the side projection inclination angle θ in the state where the inclination axis 170a is inclined most with respect to the axis 131 is, for example, greater than 0 ° and not more than 45 °. Preferably 5 ° to 20 °, in this example 10 °.

  Further, each cross-sectional outline 171 is repeatedly observed in a straight line shape and a curved line shape as the rotating body 17 rotates when viewed from a direction perpendicular to the axis 131. Specifically, in the state shown in FIG. 11A (that is, the state in which the side projection inclination angle θ is maximized), it is observed as a straight line inclined with respect to the axis 131. When the rotating body 17 rotates, each cross-sectional outline 171 is observed to change from a straight line shape to a curved line shape gradually bulging toward the base end portion 13b side (main body 12 side) of the support shaft 13, as shown in FIG. The base end portion 13b in the state shown in (b) (that is, a state in which the side projection tilt angle θ is rotated by a quarter from the maximum state and the axis 131 and the tilt axis 170a overlap). It is observed as a curved line that swells most to the side.

  Thereafter, when the rotating body 17 further rotates, each cross-sectional outline 171 is observed to gradually change from a curved line to a straight line, and the state shown in FIG. 11C (that is, the axis 131 and the inclined axis 170a In a state in which the side projection tilt angle θ is maximized again) in a direction opposite to the tilt direction shown in FIG. Observed as an inclined straight line. Thereafter, when the rotating body 17 further rotates, each cross-sectional outline 171 is observed to change from a linear shape to a curved linear shape that gradually swells toward the tip portion 13a side (the side opposite to the main body 12) of the support shaft 13, In the state shown in FIG. 11D (that is, a state in which the side projection tilt angle θ is once again maximized by a quarter of a turn and the axis 131 and the tilt axis 170a overlap). It is observed in a curved line shape that swells most toward the tip portion 13a side.

  When the rotator 17 further rotates from the state shown in FIG. 11D, each cross-sectional outline 171 is observed to gradually change from a curved line shape to a linear shape, and from the state shown in FIG. In the state of a quarter rotation, the state shown in FIG. 11A described above is obtained, and a straight line inclined with respect to the axis 131 is observed again. As shown in FIG. 2, the rotary bodies 18, 19, 20 are also formed with cross-sectional contour lines 181, 191, 201 similar to the cross-sectional contour line 171, and the same cross-sectional contour lines 182, 192, 202 is formed. It is observed in the same manner by rotating in the same manner as the rotating body 17.

  Thus, since the cross-sectional outline 171 is repeatedly observed as a straight line and a curved line as the rotating bodies 17 to 20 rotate, the user easily visually recognizes the rotation of the rotating bodies 17 to 20. be able to. Furthermore, since the strip-like surfaces 172 to 202 of the rotators 17 to 20 are formed as described above, compared to the case where the strip-like surfaces 172 to 202 are not formed (when the rotators 17 to 20 are smooth surfaces). Thus, it is possible to improve the effect of picking up the skin and the effect of relaxing the massage. In addition to this, since the contact state between the rotators 17-20 and the skin changes according to the rotation angle of the rotators 17-20, there is a slight increase or decrease in the effect of picking up the skin or the effect of loosening the itch. It contributes to the further improvement of usability.

  In addition, a plurality of cross-sectional contour lines 171 corresponding to the contours of the respective cross sections by a plurality of virtual planes K perpendicular to the inclined axis 170a inclined with respect to the axis 131 of the support shaft 13 are formed on the surface of the rotating body 17 of this example. A band-like surface 172 formed in an annular shape is formed between adjacent cross-sectional contour lines 171. Compared with the case where the cross-sectional outline 171 is formed in the same direction as the axis 131, the band-shaped surface continuously contacts the user's skin, and the contact between the main electrode 170 and the user's skin becomes a point contact. It can prevent suitably. Thereby, it becomes possible to give a user a stable electrical stimulus continuously.

  In addition, in this example, although the several strip | belt-shaped surfaces 172-202 were made into the shape hollowed gently inside the rotary bodies 17-20, it replaces with this and the shape shown to Fig.12 (a)-FIG.12 (d) It can also be. Specifically, as shown in FIG. 12A, a band-like surface 172a between adjacent cross-sectional contour lines 171 may be formed in a planar shape. The strip surface 172a is linear in a cross section including the tilt axis 170a (see FIG. 11A). Further, as shown in FIG. 12B, the band-shaped surface 172 a between the adjacent cross-sectional contour lines 171 is formed in a planar shape, and the band-shaped surface 172 b located next to the band-shaped surface 172 a is formed outside the rotating body 17. It can be a bulging shape. In addition, as shown in FIG. 12C, a band-like surface 172 a between adjacent cross-sectional contour lines 171 may be formed in a planar shape, and a linear groove 172 c may be formed along the cross-sectional contour line 171. Further, as shown in FIG. 12D, the band-like surface 172d between the adjacent cross-sectional contour lines 171 is a gently curved surface, and is smoothly connected to the adjacent band-like surface 172d, thereby rotating the rotating body 17. It may have a substantially spherical shape as a whole, and an annular line may be formed by printing using a predetermined ink on the surface of the rotating body 17 along the cross-sectional outline 171.

  In any of the above cases, the cross-sectional outline 171 is repeatedly observed in a straight line shape and a curved line shape as the rotating bodies 17 to 20 rotate, so that the user rotates the rotating bodies 17 to 20. It can be easily visually recognized. Further, except for the case shown in FIG. 12D in which the cross-sectional outline 171 is formed by printing, the effect of picking up the skin and the effect of unraveling the skin can be improved, and the effect of picking up the skin and the effect of unraveling the itching can be reduced. This can improve the feeling of use.

  Further, a spiral groove may be formed in place of the plurality of belt-like surfaces 172 to 202. Moreover, you may embed the material different from the formation material of the rotary bodies 17-20 along some strip | belt-shaped surfaces 172-202 among the said some strip | belt-shaped surfaces 172-202. As a material to be embedded, for example, a germanium alloy or a titanium alloy can be employed.

  Moreover, you may make the surface of the rotary bodies 17-20 into a smooth surface, without providing the said several strip | belt-shaped surfaces 172-202. In that case, the main electrodes 170 to 200 can be easily brought into contact with the skin. However, as compared with the case where a plurality of belt-like surfaces 172 to 202 are formed, the rotation of the rotating bodies 17 to 20 becomes difficult to understand, or the effect of picking up the skin is reduced. Furthermore, you may make it form the said some strip | belt-shaped surface in the axial direction of a rotating shaft.

  Furthermore, instead of the plurality of band-like surfaces 172 to 202, a diamond cut may be formed by combining a large number of triangular facets. Further, a pear ground made of fine irregularities may be formed on a part or all of the surfaces of the rotators 17 to 20, or minute projections made of a cone or a column may be formed. In these cases, the effect of picking up the skin and the effect of unraveling the itch can be improved as compared with the case where the rotators 17 to 20 are smooth surfaces.

  The central axis of at least one of the rotating bodies 17 to 20 may be eccentric with respect to the axis of the support shafts 13 to 16. In this case, since the rotating bodies 17 to 20 having the center axis eccentrically rotated eccentrically, the contact pressure against the skin can be increased or decreased.

  As described above, according to the present example, a good beauty effect is achieved by the cooperative action of the skin picking effect and the itching and unraveling effect by the rotating bodies 17 to 20 and the ion introduction, ion derivation, or electrical stimulation to the skin. It is possible to provide a beauty tool 1 that can be experienced and is easy to use.

(Example 2)
As shown in FIG. 13, the beauty tool 1 according to the second embodiment does not include the drive control unit 353 (see FIG. 9) according to the first embodiment. Others are the same as in the first embodiment. In this example, the control mode for detecting the submerged state in the beauty tool 1 is as follows.

  First, steps S10 to S14 (see FIG. 10) are performed as in the case of the first embodiment. Then, after it is determined in step S14 of FIG. 10 that the beauty tool 1 is submerged, a submergence detection signal is output from the submergence detector 6 to the control device 35 as shown in FIG. 14 (step S25). ). Thereafter, the current detector 34 (see FIG. 13) detects the magnitude of the weak current flowing between the main electrodes 170 to 200, and the control device 35 determines whether or not the current value is equal to or less than a predetermined value ( Step S26).

  In step S <b> 26, when it is determined that the current value between the main electrodes 170 to 200 is greater than or equal to the predetermined value (Yes in step S <b> 26), the potential difference adjustment unit 352 of the control device 35 outputs a potential difference adjustment signal to the power feeding device 33. (Step S27). When the potential difference adjustment signal is input, the power feeding device 33 reduces the amount of power fed to the main electrodes 170 to 200 and adjusts the potential difference between the main electrodes 170 to 200 to be a predetermined value or less (step S28). Thereafter, the process returns to step S11 (see FIG. 10). Moreover, also when the control apparatus 35 judges that the electric current value between the main electrodes 170-200 is less than predetermined value in step S26 (No of step S26), it returns to step S11 (refer FIG. 10).

  Thereby, when it is determined that the water is immersed, the potential difference between the main electrodes 170 to 200 is adjusted to a predetermined value or less. As a result, an excessive current is prevented from flowing between the main electrodes 170 to 200 when the main body 12 is submerged. Also in this example, the same operational effects as in the case of Example 1 are obtained. Note that the predetermined value (first predetermined value) of the current value between the main electrodes 170 to 200 and the predetermined value (second predetermined value) of the potential difference between the main electrodes 170 to 200 are set to arbitrary values. Is possible. For example, when the first predetermined value is set to a small value that is not theoretically conceivable and the second predetermined value is set to 0 V, the power feeding device 33 is determined to be submerged as in the first embodiment. To the main electrodes 170 to 200 is stopped. As in the first embodiment, it is of course possible to configure the power switch 335 to be turned off when the submerged state continues for a certain time (for example, 1 minute). Thereby, the early discharge of the battery 31 is prevented.
