Description

BEAUTY TREATMENT APPLIANCE}

The present invention relates to a beauty appliance used for beauty of the skin.

As a method for beauty of the skin, ion introduction and ion extraction have been proposed. The ion introduction is a technique of applying a charged cosmetic ingredient to the skin, then flowing a weak current having a polarity corresponding to the charge of the cosmetic ingredient, and moving the cosmetic ingredient toward the inside of the skin. By performing the ion introduction, penetration of the cosmetic ingredient into the skin is promoted, and the cosmetic ingredient can be more effectively acted. In addition, ion derivation is a method of moving a contaminant or waste matter having a charge corresponding to the polarity of the current toward the surface of the skin by flowing a weak electric current to the skin. By conducting ion extraction, contaminants and waste materials inside the skin can be effectively removed.

Patent Literature 1 discloses a facial machine in which a head portion is formed to cross a roller at the center of a loop-shaped frame. This facial machine is configured so that ion introduction and ion derivation can be performed by using the roller as an electrode. In addition to the effect of ion introduction and ion derivation, a massage effect by the roller can be expected.

Patent Document 1: Japanese Patent No. 5073441

However, the facial machine of Patent Document 1 has a limitation in increasing the contact area between the roller and the skin, because the presence of the frame is obstructed in a state in which 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 roller.

When the above arrangement is employed, for example, when a roller is brought into contact with a portion having a relatively large undulating shape such as a face to intro- duce ion introduction or ion extraction, the beauty instrument is strongly pressed against the skin, And the roller is brought into contact with the roller while being stretched. Therefore, there is still room for improvement from the viewpoint of usability of the user.

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and it is an object of the present invention to provide a beauty instrument which is excellent in usability and can experience an excellent cosmetic effect.

According to one aspect of the present invention,

A plurality of support shafts extending from the main body,

A rotating body rotatably supported by the plurality of support shafts,

A main electrode provided on a surface of at least one rotating body of the plurality of rotating bodies,

A power feeding device for supplying power from the power source to the main electrode,

An auxiliary electrode connected to the feeding device,

And a control device for controlling power supplied from the power supply device,

The control device is configured to allow an ion introduction current or an ion extraction current to flow to a closed circuit including the main electrode, the auxiliary electrode, the power supply device, and the human body while the main electrode and the auxiliary electrode are in contact with the skin And a plurality of cosmetic brushes.

The beauty device includes a body, a plurality of support shafts extending from the body, and a rotating body rotatably supported by the plurality of support shafts. In the beauty device, since the rotating body is disposed outside the body, it is difficult for the body to interfere with the skin 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 widened, and the massage effect by the rotating body can be more easily sensed.

Further, since the rotating body is disposed outside the main body, for example, when the rotating body is brought into abutment with a portion that exhibits a protruded shape relative to the periphery, It becomes difficult to interfere. As a result, the rotating body can easily be brought into contact with the base portion of the ridge portion, and ion introduction and ion extraction can be easily performed in these portions.

As described above, the beauty device has good usability in the user and can experience a good cosmetic effect.

In the cosmetic device, various waveforms such as a DC current, a pulse current, and a sinusoidal AC current can be employed as the waveforms (waveforms) of the ion introduction current and ion derivation current flowing through the skin. For example, in the case of employing a pulse current, it is preferable to appropriately set the wave height from the range of 0.05 mA or more and appropriately set the frequency from the range of 1 to 10 kHz. In addition, from the viewpoint of preventing excessive stimulation to the skin, the upper limit of the peak of the pulse current is 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. When the power source and the power feeding device are provided outside the main body, it is possible to reliably supply the ion introduction current and the power for flowing the ion leading current. In this case, since the restriction of the arrangement space is smaller than in the case where the power supply or the like is provided inside the main body, the design of the electric circuit included in the power supply device can be freely performed.

On the other hand, when the power source and the power feeding device are provided inside the main body, a cable for supplying power from the power source to the beauty device becomes unnecessary, and therefore usability of the beauty device 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 device is simplified, usability of the beauty device can be further improved.

Further, the auxiliary electrode may be provided separately from the main body, and may be connected to the feeding device via a cable. In this case, ion implantation and ion derivation can be performed even when the operator who performs ion introduction and ion extraction into the skin using the above-described beauty device and the subject who has undergone ion introduction or ion derivation are different. The beauty instrument having such a configuration can be preferably used in, for example, an aesthetic salon.

The rotating body may have a substantially spherical shape. In this case, since the rotating body brought into contact with the skin can be smoothly rotated, the operability and usability of the beauty instrument can be improved. In this case, by moving the beauty instrument along the skin, the skin is sandwiched between the adjacent rotating bodies, and a higher massage effect can be sensed. In this specification, the substantially spherical shape includes a spherical shape, an elliptical spherical shape, a roughly spherical shape, a shape recognized as an elliptical spherical shape, or a shape obtained by combining these shapes. It is acceptable that slight irregularities are provided on the surfaces of these shapes.

The plurality of support shafts are preferably arranged in a direction in which the distance between the adjacent support shafts is widened toward the front end. In this case, it is possible to naturally realize a state in which the relevant portion is inserted between adjacent rotating bodies to some extent by pressing the rotating body against a portion where effects such as a massage effect and ion introduction are desired to be obtained. In addition, in this state, by moving the beauty device along the skin, the skin is sandwiched between the adjacent rotating bodies, and a higher massage effect can be sensed. In addition, when the beauty instrument is moved along the skin, it is possible to effectively remove old horny matter and contaminants from the skin sandwiched between the adjacent rotating bodies, and in particular, to remove the remaining pores It is possible to effectively remove cold contaminants. In addition, in this case, the contact area between the rotating body and the skin can be easily widened. As a result, penetration of cosmetic ingredients into the skin by ion introduction and removal of contaminants by ion derivation can be performed more efficiently.

Further, in the above-described state, by using a beauty device in which 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 deformed . As a result, a higher massage effect can be felt. In addition, by deforming the skin so as to pick it up by hand, the skin sandwiched between the rotating bodies is easily stretched. In the case of ion introduction, the contact area between the rotating body and the skin is widened as the skin is stretched, and the stratum corneum layer on the skin surface is stretched and thinned, so that penetration of the cosmetic ingredient can be further promoted. In addition, when ions are extracted, the pores are easily opened by stretching the skin, so that contaminants inside the skin can be removed more efficiently. 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.

It is more preferable that the plurality of support shafts are arranged in a direction in which the support shafts are closer to the skin toward the tip in a state where the main body is arranged along the skin. In this case, the rotating body can be arranged between the main body and the skin by allowing the main body to follow the skin and the user holding the main body. Thus, the usability of the beauty instrument can be further improved.

In the above case, it is more preferable that the plurality of support shafts extend radially from the main body. That is, it is more preferable that the plurality of support shafts are provided so as to be closer to the skin toward the distal end and to extend outward from the main body in a state where the main body is arranged along the skin. In this case, it is possible to easily realize a state in which the plane including the rotation axis of the adjacent rotating body is tilted with respect to the skin by the user gripping the main body by allowing the main body to follow the skin. Therefore, the usability of the beauty instrument can be further improved, and the effect of the massage effect, ion introduction and ion extraction can be further enhanced.

The rotating body may have a cross-section contour corresponding to the contour on each individual cut surface when the rotating body is virtually cut by a plurality of imaginary planes perpendicular to an inclined axis inclined with respect to the rotation axis, Okay. In this case, when the rotating body is rotated, since the position of the cross-sectional contour line periodically changes according to the rotation, it can be easily visually confirmed that the rotating body is rotating.

Wherein the surface of the rotating body has a plurality of band-shaped surfaces formed in an annular shape and arranged in the axial direction of the tilted axial line, and the cross-sectional contour lines are formed so as to be visible as boundary lines of the adjacent band- It is okay to be. In this case, it is easy to visually recognize that the rotating body is rotating by the effect of the cross-sectional contour line. In addition, since the plurality of band-shaped surfaces are arranged in the axial direction of the tilted axis, the direction of the band-shaped surface periodically changes with the rotation of the rotating body, so that the effect of picking up the skin between the pair of rotating bodies And the strength is given to the annealing effect. As a result, the massage effect can be further improved, and the user can more easily feel the effect of picking up or loosening the skin, and an excellent feeling of use can be obtained.

It is preferable that the annular band-shaped surface has a shape different from other band-shaped surfaces adjacent to the band-shaped surface so that a boundary between the annularly formed band-shaped surface and another band-shaped surface adjacent in the axial direction of the inclined axis line can be easily seen. Specifically, for example, the shape of the band-shaped surface in the cross section including the inclined axis line and the other band-shaped surfaces adjacent to the inclined axis are made linear and the angle of inclination between the inclined axis and the inclined axis is different , And a belt-like surface can be formed. The shape of the band-shaped surface in the cross section including the inclined axis line may be a straight line, and the shape of another band-shaped surface adjacent to the inclined axis line may be formed in the form of a curved line, Like shape so as to have a recessed curved shape inward of the inner surface of the belt-like portion. In addition, a belt-like surface can be constituted such that the shape of the belt-like face in the cross section including the inclined axis line and the shape of the other belt-like face adjacent thereto is a curved shape which is recessed inwardly of the rotating body. In these cases, the boundary line (cross-sectional contour line) between the band-shaped surface and other band-shaped surfaces adjacent to the band-shaped surface can be clearly formed into a linear shape.

The beauty device may have 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 device can form at least two main electrodes, a power supply device, and a closed circuit including skin. By supplying a pulsed current or the like to the closed circuit, it is possible to apply electric stimulation to the portion of the skin that contacts the main electrode and to the vicinity thereof. As a result, it is expected that the cosmetic effect such as promoting blood circulation of the skin can be expected.

3, a power supply switch 335, a changeover switch 336, and a plurality of LED lamps 337 are mounted on the main circuit board 331. As shown in Fig. The main circuit board 331 is provided with a power harness 338 connected to the power supply circuit board 321 and an output harness 339 connected to the support shafts 13 to 16 . The main circuit board 331 is fixed to the board fixing table 332 with screws 333. The substrate fixing table 332 is fixed to the main body upper side so that the power supply switch 335, the changeover switch 336 and the LED lamp 337 mounted on the main circuit board 331 are opposed to the inner side surface of the main body upper side 123, And is fixed to the side portion 123 by a screw 334.

A main circuit board 331 shown in Fig. 3 is provided with a power supply device 33 for supplying power from the battery 31 to the main electrodes 170 to 200, main electrodes 170 to 200 and the power supply device 33, A current detecting section 34 for detecting the magnitude of a weak current flowing in the closed circuit including the power supply device 33 and a control device 35 for controlling the power supply device 33 are mounted.

As shown in Fig. 9, the power supply device 33 has two power feeders, i.e., a first power feeder 33a and a second power feeder 33b. Specifically, the first feeding part 33a of this example is an H bridge circuit. One output of the first feeder 33a is connected to the main electrodes 170 to 200, and the other output is connected to the auxiliary electrode 126b. The first power feeder 33a generates a potential difference between the main electrodes 170 to 200 and the auxiliary electrode 126b under the control of the controller 35 and generates a potential difference between the main electrodes 170 to 200, The auxiliary electrode 126b, and the first power feeder 33a. The first feeding part 33a is driven when the beauty device 1 is operated in a positive pulse mode or a negative pulse mode described later.

[ The current detecting portion 34 has a current measuring resistor 342 connected between the wiring 341 and the negative electrode 314 of the battery 31. [ In a state in which a weak current flows through the skin from the first power feeder 33a or the second power feeder 33b, a potential difference is generated at both ends of the current measuring resistor 342 according to the magnitude of the weak current. On the other hand, when no weak current flows through the skin from the first feeding portion 33a or the second feeding portion 33b, a potential difference does not occur at both ends of the current measuring resistor 342. [ Therefore, based on the magnitude of the potential difference inputted via the wiring 341, the control device 35 can detect whether or not a weak current flows in the skin and detect the magnitude of the weak current flowing in the skin have.

Thus, the operation of the power supply device 33 for a long time is suppressed, so that the early discharge of the battery 31 is prevented.

The power switch 335 provided on the main circuit board 331 is pressed down from the power supply device 33 via the power button 436 To 200) of the power supply. The changeover switch 336 changes the pattern of the potential difference applied to the main electrodes 170 to 200 by pressing down via the changeover button 437 (see Fig. 1) 1).

The battery 31 is a button-type battery. In this example, a CR2032-type button battery is used as the battery 31. [ Battery holding portions 312 are provided with battery connecting terminals 313 and 314 that are in electrical contact with the respective electrodes of the battery 31 to be electrically connected. The battery connection terminals 313 and 314 are connected to the power supply circuit board 321 and the power of the battery 31 is supplied to the power supply circuit board 321. [ A lid 311 for covering the battery holding portion 312 is detachably provided on the main body lower side portion 124. An O-ring 311a is interposed between the main body lower portion 124 and the lid 311 so that the space between the main body lower portion 124 and the lid 311 is sealed.

2, the main body lower portion 124 is provided with a submersion sensor 60 as a submergence detecting portion 6 for detecting submersion of the main body 12 and outputting a submergence detecting signal. The submergence sensor 60 is located in the vicinity of the connecting portion 130b between the main body 12 and the rotating bodies 19 and 20 (main electrodes 190 and 200) described later.

The O-ring 62 seals between the wall surface of the mounting hole 61 and the water hammer sensor 60. The submergence sensor 60 is fitted in a slit 64a formed in the fixing plate 64. [ Then, the fixing plate 64 is mounted on the inner surface of the lower main body portion 124 by screws 65. Thus, the submergence sensor 60 is attached to the main body lower portion 124 via the fixing plate 64. [ The submergence sensor 60 is electrically connected to the main circuit board 331 via a sensor harness 63.

It is possible to detect the submergence of the main electrodes 170 to 200 by arranging the submergence sensors 60 in the rotors 17 to 20. [ The beauty instrument 1 may be used in a state in which a conductive gel is applied to the skin to increase the conductivity to the skin. In this case, when the pair of the submergence detecting electrodes 60a and 60b touch the skin, the electric resistance between the submergence detecting electrodes 60a and 60b is lowered by a predetermined level due to the influence of the conductive gel, There is a possibility of erroneous detection). Therefore, when the submergence sensor 60 is disposed in the rotating bodies 17 to 20, it is preferable to mount the submergence sensor 60 on a portion not in contact with the user's skin. The submergence sensor 60 may be disposed in both the main body 12 and the rotating bodies 17-20.

A lower surface cover 128 is attached to the lower surface of the main body lower portion 124. A plurality of latching grooves 124a are formed in the main body lower side portion 124 and a plurality of latching claws 128a are formed in the lower surface cover 128. [ The lower surface cover 128 is fixed to the lower surface of the main body lower portion 124 as a plurality of the engagement claws 128a are caught by the engagement grooves 124a. A sensor hole 128b is formed in the lower surface cover 128 at a position facing the mounting hole 61 of the lower main body portion 124.

[ An O-ring 219 inserted into the support shaft 13 is interposed between the support shaft 13 and the wall surface of the through hole 128d to seal the space therebetween.

Similar to the rotating body 17, the other rotating bodies 18 to 20 are also mounted on the body 12 via the supporting shafts 14 to 16. 2, the rotating bodies 17 and 18 are connected to the connecting portion 130a of the lower surface of the main body 12, and the rotating bodies 19 and 20 are connected to the connecting portions 130a of the main body 12, And is connected to the lower connecting portion 130b. The supporting shafts 13 to 16 are arranged such that the rotating bodies 17 to 20 are positioned on an inclined shape whose tip extends from the upper portion to the lower portion of the main body 12, that is, an axis extending radially.

(The distance between the end portions on the opposite sides of the main body 12 in the support shafts 13 and 14) between the pair of support shafts 13 and 14 and the support shaft 15 And 16 are all equal to L1. The support axes 13 and 15 and the support axes 14 and 16 between the pairs are also configured so that their axial spacing L2 is the same. The axial distance L2 between the support shafts 13 and 15 and the support shafts 14 and 16 between the pairs is larger than the axial distance L2 between the support shafts 13 and 14 and the support shafts 15 and 16 Is larger than the interval L1.

Although not shown, an angle (angle) between the axis 151 of the support shaft 15 and the axis 161 of the support shaft 16 in the cross section parallel to the support shaft 15 and the support shaft 16 Is the same as the angle alpha formed by the axis 131 and the axis 141. [ 7, when viewed from the direction in which the center of the rotating body 17 and the center of the rotating body 18 are overlapped with each other, The angle beta formed between the line T and the axes 131 and 141 of the support shafts 13 and 14 is 30 deg.

When the beauty instrument 1 of this embodiment is used, when the rotary bodies 17 to 20 are rotated in contact with the skin, the skin and muscles are pressed or lifted by the rotary bodies 17 to 20 to be released. The operation of the power supply button 436 causes the beauty device 1 to operate the power supply device 33 by the electric power from the battery 31 mounted in the main body 12, Electric power is supplied to the main electrodes 170 to 200 via the main electrodes 170 to 200.

In addition, the beauty instrument 1 can change the operation mode and change the waveform of the potential difference applied to the main electrodes 170 to 200 by operating the changeover button 437. [ Specifically, the beauty instrument 1 of the present embodiment has three operation modes of 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 have high potentials to be. 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 low potential to be. 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 ion introduction or ion derivation is performed. The ion introduction is a technique of applying a charged cosmetic ingredient to the skin, then flowing a weak current having a polarity corresponding to the charge of the cosmetic ingredient, and moving the cosmetic ingredient toward the inside of the skin. For example, in the case of ion introduction of a cosmetic component having a negative charge by using the cosmetic device 1 of this embodiment, the main electrodes 170 to 200 are brought into contact with the skin to which the cosmetic component has been previously applied, (1) may be operated in a negative pulse mode. By operating the beauty instrument 1 in the negative pulse mode, the closed circuit including the main electrodes 170 to 200, the auxiliary electrode 126b, the feeder 33, An ion-introducing current for promoting the penetration of the ions into the atmosphere can be generated.

The ion derivation is a method of moving a contaminant or the like having a charge corresponding to the polarity of the current to the skin surface by flowing a weak electric current to the skin. For example, in the case where contaminants or the like having negative charges are to be removed from the inside of the skin by using the beauty device 1 of this embodiment, the main electrodes 170 to 200 are brought into contact with the skin, It can be operated in the positive pulse mode. By operating the beauty device 1 in the positive pulse mode, it is possible to generate an ion-induced current that moves contaminants or the like out of the skin to the closed circuit.

It is also possible to remove contaminants or the like which are not charged by bonding the cleaning component charged with the contaminant to the contaminant before conducting ion extraction. For example, by attaching the cleaning component having negative charge to the contaminant in advance, a negative charge is imparted to the contaminant. Thereafter, by moving the main electrodes 170 to 200 against the skin and operating the beauty device 1 in the positive pulse mode, contaminants can be moved to the skin surface as in the 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 flowing 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 appropriately set in the range of 1 Hz to 10 kHz.

The AC pulse mode is used when electrically stimulating a portion of the skin that contacts the main electrodes 170 to 200 and its vicinity. That is, by performing the AC pulse mode in a state in which the main electrodes 170 to 200 are in contact with the skin, the main electrodes 170 and 180, the skin, the main electrodes 190 and 200, ) Can generate a weak alternating-current pulse current in the closed circuit including the electrode, thereby giving electrical stimulation 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 through the closed circuit becomes 0.1 mA or more. By flowing a weak current of 0.1 mA or more to the closed circuit, the electric stimulation to the skin can be sufficiently sensed and a sufficient cosmetic effect can be expected to be obtained.

In addition, since excessive stimulation is prevented from being applied to the skin in any one of the positive pulse mode, the negative pulse mode and the AC pulse mode, the weak current flowing in the skin is 2.5 mA or less It is necessary to control the potential difference as much as possible.

These operation modes can be executed while the beauty instrument 1 is stopped. However, by rotating the rotating bodies 17 to 20 in contact with the skin and performing the operation mode, , A good cosmetic effect can be expected by cooperating action of ion derivation or electric stimulation and the above relaxation by rotation of the rotating bodies 17 to 20.

At the moment when the rotating bodies 17 to 20 are brought into contact with the skin, since the contact portions of the rotating bodies 17 to 20 are very narrow, the weak electric current flowing through the skin concentrates on the narrow contact portions, . In order to avoid this, when the skin contacts the rotating bodies 17 to 20, that is, when a weak current flows from the main electrodes 170 to 200 to the skin, It is also possible to perform a so-called slow start control in which the potential difference adjusting unit 352 gradually raises the weak current between the two from the low value.

Next, the control state for detecting the submergence state in the beauty device 1 will be described in detail below.

As shown in Fig. 10, first, the power switch 335 is turned on (step S10). Thereafter, the electrical resistance between the pair of submerged detection electrodes 60a and 60b (see Fig. 2) in the submergence sensor 60 is detected (step S11). Then, the submergence detecting unit 6 judges whether or not the electric resistances of the pair of submergence detecting electrodes 60a and 60b are equal to or smaller than a predetermined value (step S12). If the water hammer detection unit 6 determines that the electric resistance is not equal to or smaller than the predetermined value (No at step S12), the power supply device 33 is controlled by the control device 35 (drive control unit 353) The power of the battery 31 is supplied to the electrodes 170 to 200 (step 13). Thereafter, the process returns to step S11.

If the water detecting unit 6 determines in step S12 that the electric resistance is equal to or smaller than the predetermined value (Yes in step S12), the beauty detection apparatus 6 determines that the beauty tool 1 is underwater (step S14) , And outputs a detection signal to the control device 35 (step S15). Then, the control device 35 determines whether or not the power supply device 33 is supplying power to the main electrodes 170 to 200 (step S16). When it is determined that the power feeding device 33 does not supply power to the main electrodes 170 to 200 (No in step S16), the process returns to step S11.

If it is determined in step S16 that the power feeding device 33 is supplying power to the main electrodes 170 to 200 (Yes in step S16), the drive control section 353 of the control device 35 controls the power feeding device 33 (Step S17). Then, the power supply device 33 stops power supply to the main electrodes 170 to 200 (step S18). Thereafter, the flow returns to step S11. When the control device 35 receives the submergence detection signal from the submergence detecting section 6, the drive control section 353 outputs a stop signal to the power supply device 33 without performing the determination process of step S16 .

Thus, when it is determined that the motor is in the submerged state, the power supply to the rotating bodies 17 to 20 is controlled to be stopped. As a result, it is possible to reliably prevent an excessive current from flowing between the main electrodes 170 to 200 when the main body 12 is submerged. In Fig. 10, the process returns to step S11 after the process of step S18. However, after the process of step S18 is completed, the power switch 335 may be turned off, and the process shown in Fig. 10 may be terminated. In this case, 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 submerged detection signal, the user again performs the operation of turning on the power switch 335 Power supply from the power supply device 33 to the main electrodes 170 to 200 is not resumed. Thus, the power supply to the main electrodes 170 to 200, which is not intended by the user, can be preferably prevented from being resumed, and the early discharge of the battery 31 is prevented. It is of course possible to turn off the power switch 335 when the submergence state continues for a predetermined time (for example, one minute). After the power supply from the power supply device 33 to the main electrodes 170 to 200 is stopped, the display of the display portion 52 is switched from the display of the operation mode of the power supply device 33 to the state in which the main body 12 is submerged May be switched to a display for informing the user. As a result, it is possible to inform the user that the main body 12 is inundated.

The beauty instrument 1 of the present embodiment has the above-described configuration, and when the main body 12 is submerged, the submergence detection unit 6 detects the submergence and outputs a submergence detection signal. The drive control unit 353 controls the voltage applied to the main electrodes 170 to 200 by the power supply unit 3 by inputting the detection signal to the control unit 35. [ As a result, excessive current flow between the main electrodes 170 to 200 can be suppressed even if the electrical resistance between the main electrodes 170 to 200 is excessively lowered. As a result, it is possible to prevent problems such as an electric shock of the user, an excessive load on electronic parts in the beauty instrument 1, and a large amount of electric power consumed unnecessarily. Therefore, even when used in a place where there is a fear of submersion in a bathroom or the like, there is no need to tilt the special circumference, and the usability is good.

Further, in the present example, since the submergence detecting portion 6 is provided separately from the main electrodes 170 to 200, even when a conductive gel or the like is applied to the skin, misdetection of the submerged state by the gel is suppressed Therefore, even if the gel is used, the usability is good.

The four main electrodes 170 to 200 provided in the beauty device 1 of the present embodiment are formed on the surfaces of the conductive rotators 17 to 20. When the beauty instrument is used, for example, the user grasps the grip portion 122 of the main body 12 and presses the rotating bodies 17 to 20 against the skin, and as shown in Figs. 1 and 2, And moves the beauty instrument 1 in P1 (or P2 direction). At this time, since the preceding pair of rotating bodies 17 and 18 (or the pair of rotating bodies 19 and 20) extend toward the front side in the moving direction, the pair of preceding rotating bodies 17, 18 (or the pair of rotating bodies 19, 20) rotate inward and the skin is pressed, and the massage effect is shown. On the other hand, since the pair of later rotating bodies 19 and 20 (or the pair of rotating bodies 17 and 18) extend toward the rear side in the moving direction, the pair of succeeding rotating bodies 19 and 20 (Or a pair of rotating bodies 17 and 18) rotates inward and the skin is picked up between the rotating bodies 19 and 20 (or both rotating bodies 17 and 18) Loses. That is, by the movement in one direction (P1 direction or P2 direction) of the main body 12, another massage effect such as pressing and picking up is performed on the same part of the skin.

Also, in the case of moving the beauty device 1 in the Q1 direction and the Q2 direction, as in the case of the P1 and P2 directions described above, the pair of preceding rotating bodies 17 and 19 (or the pair of rotating bodies The pair of rotating bodies 18 and 20 (or the pair of rotating bodies 17 and 19) are rotated inward to pick up the skin, So that different massage effects such as pressing and picking up can be obtained for the same part of the skin.

The axial distance L1 between the rotating bodies 17 and 19 and the rotating bodies 18 and 20 is smaller than the axial distance L2 between the rotating bodies 17 and 18 and the rotating bodies 19 and 20. Therefore, by moving the beauty instrument 1 in the P1 direction or the P2 direction, the portion of the body such as an arm or an ankle having a large curvature can be moved between the rotating bodies 17 and 18 and between the rotating bodies 19 and 20 ), It is possible to massage effectively.

The rotating bodies 17 to 20 have a sphere shape. Thereby, the rotating bodies 17 to 20 can be smoothly rotated in a state in which the rotating bodies 17 to 20 are in contact with the skin, and the feeling of use is excellent. In addition, the effect of picking up and loosening of the skin can be exhibited, and the massage effect can be further improved. It is also possible to form the rotating bodies 17 to 20 in an elliptical sphere shape or a shape in which spherical shape and elliptical sphere shape are combined.

In addition, at the time of using the beauty instrument 1, the skin inserted between the adjacent rotating bodies 17 to 20 can be deformed so as to stretch by the picking up effect. Therefore, as described above, the effects of ion introduction and ion derivation can be further enhanced. In addition, the contact area between the skin and the main electrodes 170 to 200 tends to be widened by the above pick-up effect. Therefore, it is possible to make it difficult to cause current concentration to a narrow area when a weak current flows from the main electrodes 170 to 200 to the skin. Therefore, the beauty instrument 1 can easily avoid an excessive stimulation to the skin due to the weak current, thereby improving usability.

The distance M1 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. The main electrodes 170 and 180 of the rotating bodies 17 and 18 and the main electrodes 190 and 190 of the rotating bodies 19 and 20 having a large interval are disposed in a state in which the beauty instrument 1 is operating in the AC pulse mode. , 200 are provided with a potential difference between them. Therefore, in the AC pulse mode, since a current can be supplied to the skin of a relatively wide range between the main electrodes 170 to 200, a current does not locally flow and an appropriate electrical stimulation can be obtained. In addition, when the power supply device 33 is operated, the magnitude of the weak current flowing through the skin is detected by the current detection unit 34 and the control device 35, and when the detected current value is equal to or greater than the predetermined value, The potential difference from the power supply device 33 is reduced by the capacitor 352. For this reason, even when the skin is wet and the electric resistance is small, there is no possibility that the electric current is excessively flowed to the skin and strong electrical stimulation is given.

In addition, 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 to the skin can be enhanced . As a result, a potential difference can be surely provided between the main electrodes 170 and 180 and the main electrodes 190 and 200, effectively applying electrical stimulation to the skin. In particular, even when the skin is in a dry state, it is possible to effectively apply electrical stimulation to the skin. The kind of conductive gel to be used is not particularly limited, and any known conductive gel may be used. For example, a conductive gel showing a receiving (diet) effect can be used. Thus, in addition to the massage effect and the electrical stimulation, the reception effect can be exhibited.

In this example, the water immersion detection unit 6 is provided in the main body 12. [ Thus, when the conductive gel is applied to the skin and used, the interference of the gel with the water detecting portion 6 is suppressed, so that erroneous detection of the submerged state by the gel is further suppressed . Therefore, usability when the gel is used is further improved.

In this example, the main body 12 can be gripped, and the submergence detecting portion 6 is provided in the vicinity of the connecting portion 130b with the main electrodes 190 and 200 in the main body 12. [ Thereby, it is possible to suppress the hand from touching the submergence detecting portion 6 when the main body 12 (the grip portion 122) is gripped. As a result, it is possible to suppress erroneous detection in the submerged state, and it is possible to reliably detect the submergence state even when the beauty instrument 1 is submerged in the state of holding the main body 12 (the gripper 122) .

11A, on the surface of the rotating body 17, a plurality of imaginary faces K perpendicular to the inclined axis 170a inclined with respect to the axis line 131 of the support shaft 13 A plurality of cross-sectional contour lines 171 corresponding to the contours of the respective cross-sections are formed. Between the adjacent cross-sectional contour lines 171, a band-shaped surface 172 formed in a ring shape is formed. Each band-shaped surface 172 is gently recessed toward the inside of the rotating body 17. Each of the band-shaped surfaces 172 is arranged in the axial direction of the tilted axis 170a and the sectional contour line 171 is formed so as to be visible as a boundary line in the band-shaped surface 172 adjacent to each other have. In each band-shaped surface 172, its width (that is, the length in the axial direction of the oblique axis 170a) is substantially constant.

The rotating body 17 is rotatable about the axis 131. [ 11 (a) to 11 (d), the lateral projection inclination angle [theta] of the inclined axis 170a with respect to the axis 131 when viewed from the direction perpendicular to the axis 131 ) Is observed to change in accordance with the rotation of the rotating body 17. As shown in Figs. 11A and 11C, the lateral projection inclination angle [theta] in a state in which the inclined axis 170a is inclined with the axis 131 as an axis is, for example, 0 Deg. And 45 deg., Preferably 5 deg. To 20 deg., And in this example, 10 deg.

When viewed from a direction perpendicular to the axial line 131, each of the cross-sectional contour lines 171 is observed repeatedly along the rotation of the rotary body 17 as a straight line and a curved line. Concretely, in a state shown in Fig. 11A (i.e., a state in which the lateral projection tilt angle [theta] becomes maximum), a straight line oblique to the axis 131 is observed. When the rotating body 17 is rotated, each of the cross-sectional contour lines 171 gradually changes from a linear shape to a curved line that gradually bulges from the proximal end 13b side of the support shaft 13 (toward the main body 12) And the axial line 131 and the inclined axis line 170a are overlapped with each other in the state shown in Fig. 11 (b) (i.e., the state in which the lateral projection inclination angle [theta] State) to the proximal end portion 13b side.

11 (c) (that is, in the state of the axis 131), the cross-sectional contour 171 is gradually changed from a curved line shape to a linear shape when the rotating body 17 further rotates, (A state in which the side projection angle? Is maximized and the state in which the projection angle? Is further increased by 1/4 from the state in which the inclination axis 170a is overlapped with the inclination axis 170a) It is observed as a straight line inclined in the direction opposite to the inclining direction. Thereafter, when the rotating body 17 further rotates, each of the cross-sectional contour lines 171 is curved from the linear shape gradually toward the tip end 13a side (opposite side to the main body 12) of the support shaft 13 Is changed from the state in which the lateral projection tilt angle? Is once again maximized and the state in which the tilt axis 170a and the tilt axis 170a ) Are superimposed on the tip 13a side.

11 (d), it is observed that each of the cross-sectional contour lines 171 gradually changes from a curved line shape to a linear shape when the rotating body 17 further rotates. In Fig. 11 (d) 11 (a), and is again obliquely observed with respect to the axial line 131. In this state, as shown in Fig. As shown in Fig. 2, the rotating bodies 18, 19 and 20 are formed with the same cross-sectional contour lines 181, 191 and 201 as the cross-sectional contour line 171, , 192, and 202 are formed. Is rotated in the same manner as the rotating body 17 and observed in the same manner.

As described above, the straight line shape and the curved line shape are repeatedly observed in the cross-sectional contour line 171 in accordance with the rotation of the rotating bodies 17 to 20, so that the user can easily confirm the rotation of the rotating bodies 17 to 20 . In addition, since the band-shaped surfaces 172 to 202 of the rotating bodies 17 to 20 are formed as described above, when the band-shaped surfaces 172 to 202 are not formed (the rotating bodies 17 to 20) Is a smooth surface), the effect of picking up and loosening of the skin can be improved. In addition, since the contact state of the rotating bodies 17 to 20 with the skin changes in accordance with the rotation angle of the rotating bodies 17 to 20, the skin picking up effect and the loosening effect are slightly complicated And further contributes to improvement of feeling.

The surface of the rotating body 17 of the present embodiment corresponds to the outline of each section formed by the plurality of virtual surfaces K perpendicular to the inclined axis 170a inclined with respect to the axis 131 of the support shaft 13 And a band-shaped surface 172 formed in a ring shape is formed between the adjacent cross-sectional contour lines 171. As shown in Fig. As compared with the case in which the contour line 171 is formed in the same direction as the axis 131, the contact between the main electrode 170 and the skin of the user becomes continuous when the band- It is possible to preferably prevent the occurrence of point contact. This makes it possible to give the user a stable electrical stimulation continuously.

In this example, the plurality of belt-shaped surfaces 172 to 202 are formed to have a recessed shape gently inside the rotating bodies 17 to 20, but instead of those shown in Figs. 12 (a) to 12 d) may be used. Specifically, as shown in Fig. 12 (a), the band-shaped surface 172a between the adjacent cross-sectional contour lines 171 may be formed in a planar shape. The band-shaped surface 172a has a straight line in a cross section including the inclined axis line 170a (see FIG. 11A). As shown in Fig. 12 (b), the belt-like surface 172a between the adjacent cross-sectional contour lines 171 is formed in a planar shape, and the belt- The belt-shaped surface 172b may be formed to swell outwardly of the rotating body 17. 12 (c), the band-shaped surface 172a between the adjacent cross-sectional contour lines 171 is formed in a planar shape, and the linear groove 171 is formed along the contour line 171 172c may be formed. 12 (d), the belt-shaped surface 172d between the adjacent cross-sectional contour lines 171 is a smooth curved surface and is smoothly connected to the adjacent belt-shaped surface 172d And an annular line is formed by printing using a predetermined ink on the surface of the rotating body 17 along the cross-sectional contour line 171 as well as a substantially spherical shape as a whole of the rotating body 17 It is okay to have it.

In any of the above cases, the straight line shape and the curved line shape are repeatedly observed in the cross-sectional contour line 171 according to the rotation of the rotating bodies 17 to 20, so that the user can easily rotate the rotating bodies 17 to 20 I can admit it. In addition, it is possible to improve the pick-up effect and the loosening effect of the skin, except for the case shown in Fig. 12 (d) in which the cross-section contour line 171 is formed by printing, And it is possible to further improve the feeling of use.

Instead of the plurality of belt-shaped surfaces 172 to 202, spiral grooves may be formed. It is also possible to embed materials other than the materials for forming the rotating bodies 17 to 20 along the band-shaped surfaces 172 to 202 in the plurality of band-shaped surfaces 172 to 202. [ As the material to be embedded, for example, a germanium alloy or a titanium alloy can be employed.

Further, the surface of the rotating bodies 17 to 20 may be a smooth surface without providing the plurality of belt-like surfaces 172 to 202. [ In this case, it is easy to contact the main electrodes 170 to 200 with the skin. However, as compared with the case where a plurality of band-shaped surfaces 172 to 202 are formed, it becomes difficult to know the rotation of the rotating bodies 17 to 20, or the effect of picking up the skin is reduced. Further, the plurality of band-shaped surfaces may be formed in the axial direction of the rotation axis.

Instead of the plurality of belt-shaped surfaces 172 to 202, a diamond cut may be formed by combining small planes of a triangle. A satin surface made of fine irregularities may be formed on part or all of the surfaces of the rotating bodies 17 to 20, or a minute projection formed of a conical shape or a cylindrical shape may be formed. In these cases, it is possible to improve the picking up effect and the loosening effect of the skin, as compared with the case where the rotating bodies 17 to 20 are smooth faces.

The center axis of at least one of the rotating bodies 17 to 20 may be eccentric with respect to the axis of the supporting axes 13 to 16. In this case, since the rotating bodies 17 to 20 with the center axis being eccentrically rotated eccentrically, the contact pressure to the skin can be made stronger.

As described above, according to this example, a good cosmetic effect can be obtained by the action of picking up or loosening the skin by the rotating bodies 17 to 20 and the cooperative action of ion introduction, ion extraction or electrical stimulation to the skin It is possible to provide a beauty appliance 1 having good usability.

(Example 2)

As shown in Fig. 13, the beauty device 1 according to the second embodiment does not include the drive control section 353 (see Fig. 9) of the first embodiment. The others are the same as those of the first embodiment. In this example, the control state for detecting the submergence state in the beauty device 1 is as follows. The same constituent elements as those of the first embodiment are denoted by the same reference numerals, and a description thereof will be omitted.

First, steps S10 to S14 (see Fig. 10) are performed as in the case of the first embodiment. 14, the submergence detection unit 6 outputs a submergence detection signal to the control unit 35 (step S14 in Fig. 10), as shown in Fig. 14 S25). Thereafter, the magnitude of the weak current flowing between the main electrodes 170 to 200 is detected by the current detection unit 34 (see Fig. 13), and the control device 35 determines whether or not the current value is equal to or smaller than the predetermined value (Step S26).

When it is determined in step S26 that the current value between the main electrodes 170 to 200 is equal to or larger than the predetermined value (Yes in step S26), the potential difference adjusting section 352 of the control device 35 applies the potential difference adjusting signal (Step S27). When the potential difference adjusting signal is inputted, the feed device 33 reduces the amount of feeding to the main electrodes 170 to 200 and adjusts the potential difference between the main electrodes 170 to 200 to be equal to or smaller than a predetermined value (step S28) . Thereafter, the flow returns to step S11 (see Fig. 10). If the control device 35 determines in step S26 that the current value between the main electrodes 170 to 200 is less than the predetermined value (No in step S26), the process returns to step S11 (see FIG. 10).

Thus, when it is determined that the submerged state is present, the potential difference between the main electrodes 170 to 200 is adjusted to a predetermined value or less. As a result, excessive current flows between the main electrodes 170 to 200 when the main body 12 is submerged. Also in this example, the same function and effect as those of the first embodiment are exhibited. It is also possible to set a predetermined value (first predetermined value) of the current value between the main electrodes 170 to 200 and a predetermined value (second predetermined value) of the potential difference between the main electrodes 170 to 200 to an arbitrary value It is possible. For example, in the case where the first predetermined value is set to a small value that can not be theoretically considered and the second predetermined value is set to 0 V, 170 to 200 is stopped. As in the first embodiment, it is of course possible to turn off the power switch 335 when the submergence state continues for a predetermined time (for example, one minute). As a result, the early discharge of the battery 31 is prevented.

Further, when a plurality of rotary devices for cosmetic devices are used in combination, the effect of picking up and loosening of the skin between the pair of rotary devices for cosmetic devices can be exhibited, and the massage effect can be further improved . (1), the spherical shape and the elliptical spherical shape are not limited to the exact spherical shape and the elliptical spherical shape but may be a shape in which the spherical shape and the elliptical spherical shape are roughly recognized, And includes approximately spherical shapes.
