Description

The present invention relates to a massage device that obtains a massage effect by electrical stimulation.

Conventionally, as this type of massager, for example, configurations as disclosed in Patent Literature 1 and Patent Literature 2 have been proposed.
In the conventional configuration described in Patent Document 1, a pair of electrodes is provided on a pad that can adhere to skin such as a face. A stimulus generator is connected to both electrodes via a conductive wire. And
With the pad attached to the skin such as the face, a pulse signal is applied to both electrodes from the stimulation generator, so that electrical stimulation is applied to the skin and blood circulation is promoted. .

However, in the configurations described in Patent Document 1 and Patent Document 2, when the massager is submerged, the electrical resistance between the pair of electrodes to which a potential difference is applied is excessively decreased between the pair of electrodes. Current may flow through In this case, if the user touches the massager or water that is energized, an electric shock may be caused, an excessive load will be applied to the electronic components in the massager, etc., or a large amount of power may be wasted. And other problems such as consumption. Therefore, when using it in a bathroom or the like where the massage device may be submerged, it is inconvenient because it requires attention to avoid the above-mentioned problems.

In addition, in order to prevent an excessive current from flowing between the pair of electrodes, it is determined that the electrical resistance between the pair of electrodes is submerged when the electrical resistance between the pair of electrodes is equal to or less than a predetermined value. It may be possible to stop power supply. However, in such a massage device, in order to promote the flow of current from the electrode to the skin, a conductive gel or the like is applied to the skin, and the gel is interposed between the electrode and the skin. Sometimes. And when the said gel is used, it is possible that an electric current flows between a pair of electrodes via the said gel, and the electrical resistance between the said pair of electrodes temporarily becomes below a predetermined value. Then, as described above, if the electrical resistance between the pair of electrodes is equal to or lower than a predetermined value, it is determined that the state is submerged and power supply to the pair of electrodes is stopped. There is a possibility that the power supply is unexpectedly stopped due to an erroneous determination that the state is sometimes submerged. Therefore, when using a conductive gel, it is inconvenient.

The present invention has been made in view of such a background, and provides an easy-to-use massage device that can give a good massage effect by applying electrical stimulation to the skin and can suppress the occurrence of problems due to submersion. There is.

One aspect of the present invention is a massage device including a main body and a rotating body provided to be rotatable around an axis extending from the main body.
A cross-sectional contour line corresponding to the contour of each cross section in a plurality of virtual planes perpendicular to the tilt axis inclined with respect to the axis is formed on the surface of the rotating body.

According to the massage device, since a potential difference is applied between at least two electrodes, a massage effect is produced by bringing the electrodes into contact with the skin and applying electrical stimulation to the skin. And when the main body and / or electrode of the massager are submerged, the submergence detection unit detects the submergence and outputs a submergence detection signal. Then, when the submergence detection signal is input to the control unit, the control unit controls the potential difference applied between the electrodes by the power feeding unit. Thereby, even if the electrical resistance between the electrodes decreases excessively due to submergence, it is possible to suppress excessive current from flowing between the electrodes. As a result, it is possible to prevent problems such as electric shock by the user, excessive load on the electronic components in the massage device, and 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 addition, since the submergence detection unit is provided separately from the electrode, even when a conductive gel or the like is applied to the skin, erroneous detection of the submergence state due to the gel is suppressed, and the gel Easy to use even when using.

As described above, according to the present invention, it is possible to provide an easy-to-use massage device that can give a good massage effect by applying electrical stimulation to the skin and can suppress the occurrence of problems due to submersion.

As a result, it is possible to effectively prevent an excessive current from flowing between the electrodes. The first predetermined value of electric resistance can be determined as appropriate. Similarly, the second predetermined value of the potential difference can be determined as appropriate. For example, by setting the second predetermined value of the potential difference to 0 V, it is possible to prevent current from flowing between the electrodes when the submergence detection signal is input.

For example, the shape of the belt-like surface in the cross section including the tilt axis and the other belt-like surfaces adjacent thereto can be linear, and the tilt angles of the two with respect to the tilt axis can be made different. 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 It can be.

The electrode preferably has flexibility. In this case, since the electrode is easily deformed along the shape of the skin, it is easy to ensure a wide contact area between the electrode and the skin.
Therefore, electrical stimulation can be given to a wide range simply by attaching the electrode to the skin, and the massage effect can be exerted on a wider range. In this case, for example, the electrode can be formed in a sheet shape that is integrated with the main body by being extended from the main body and can be attached to the skin together with the main body. Further, the electrode can be formed in a pad shape that is connected to the main body via a cord and can be attached to the skin.

An output harness 339 is attached to an end 13b of the support shaft 13 on the main body 12 (see FIG. 2) side via a screw 13e. The support shaft 13 is made of a conductive metal (in this example, a stainless alloy), and the output harness 339 and the support shaft 13 can be energized.

As shown in FIG. 3, the end 13 b of the support shaft 13 on the main body 12 (see FIG. 2) side is inserted through a through hole 128 d provided in the lower surface cover 128 and provided on the lower side portion 124 of the main body. The support hole 124d is inserted. The support hole 124d has a D-shape so as to follow the outer shape of the expanded diameter portion 13c, and the expanded diameter portion 13c of the support shaft 13 is supported by the support hole 124d.
Located in. Thus, the support shaft 13 is prevented from rotating. An E-ring 218 for retaining is attached to the end 13 b located in the main body 12. An O-ring 219 inserted through the support shaft 13 is interposed between the support shaft 13 and the wall surface of the support hole 128d to seal between the two.

The other rotators 18 to 20 are also attached to the main body 12 via the support shafts 14 to 16 in the same manner as the rotator 17. Thus, as shown in FIG. 2, the rotators 17 and 18 are connected to the connection portion 130 a on the lower surface of the main body 12, and the rotators 19 and 20 are connected to the connection portion 130 b on the lower surface of the main body 12. Yes. Further, the support shafts 13 to 16 are arranged so that the rotating bodies 17 to 20 are positioned on an inclined axis that extends forward from the upper part to the lower part of the main body 12, that is, on an axial line that extends radially.

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. Also, the support shafts 13 and 15 and the support shaft 14 between the pair,

, 14 and the support shafts 15 and 16 are configured to be larger than the axial interval L1.

As shown in FIG. 8, the angle α formed by the p-axis line 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 °. More preferably, it is 70 °. Although not shown, in the cross section parallel to the support shaft 15 and the support shaft 16, the angle formed by the support shaft 15 and the support shaft 16 is the same as the angle α formed by the support shaft 13 and the support shaft 14. 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. Further, when viewed from the direction in which the center of the rotating body 19 and the center of the rotating body 20 overlap, the virtual line T and the support shaft 1

The diameter of each of the rotating bodies 17 to 20 is preferably 38 to 45 mm, and 40 mm.
More preferably. The diameters of the rotating bodies 17 to 20 may all be the same, or some of the diameters may be different from other diameters.

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

When the massage device 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 massaged. Further, the outer surfaces of the rotating bodies 17 to 20 form electrodes 170 to 200, and the power feeding device 33 is operated by the power from the battery 31 mounted in the main body 12, and the electrodes 170, A potential difference is applied between 180 and the electrodes 190 and 200. Then, when the electrodes 170 to 200 are brought into contact with the skin, a weak current flows through the skin between the electrodes 170 to 200, and electrical stimulation is given to the skin. As a result, electrical stimulation and rotating bodies 17-20
A good massage effect can be obtained by the cooperative action with the above-mentioned kneading and unwinding.

The potential difference generated between the electrodes 170 and 180 and the electrodes 190 and 200 can be set as appropriate. However, when the potential difference is too large, the electrical stimulation to the skin becomes excessive and the user may feel pain, which is not preferable. On the other hand, when the potential difference is too small, it is difficult for the user to obtain a bodily sensation with respect to electrical stimulation. For example, the potential difference can be set so that the weak current is 0.1 to 1.25 mA.

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, so that the weak current flowing between the two is concentrated on the narrow contact portion, thereby causing excessive electric power to the user. May cause irritation. In order to avoid this, when the rotating bodies 17 to 20 and the skin come into contact with each other, that is, the electrical resistance detector 34 that detects the electrical resistance between the electrodes 170 to 200.
However, by detecting that the electric resistance has changed to a predetermined value or less, the rotating bodies 17 to 20
When the contact between the skin and the skin is detected, 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, a control mode for detecting a submerged state in the massage device 1 will be described in detail below.
As shown in FIG. 10, first, the 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). The submergence detection unit 6 includes a pair of submergence detection electrodes 60a and 6a.
It is determined whether or not the electric resistance of 0b is equal to or less than a predetermined value (step S12). Submergence detection unit 6
However, if it judges that the said electrical resistance is not below a predetermined value (No of step S12), the control part 3 will be described.
5 (power supply control unit 353), the power supply apparatus 33 supplies power to the electrodes 170 to 200 (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), it determines that the massage device 1 is in a submerged state (step S).
14) The submergence detection unit 6 outputs a submergence detection signal to the control unit 35 (step S15). And the control part 35 judges whether the electric power feeder 33 is supplying electric power to the electrodes 170-200 (step S16). When it is determined that the power supply apparatus 33 is not supplying power to the 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 feeding power to the electrode (Yes in step S16), the power feeding control unit 353 of the control unit 35 outputs a stop signal to the power feeding device 33 (step S17). And the electric power feeder 33 stops the electric power feeding to the electrodes 170-200 (step S18). Thereafter, the process returns to step S11. When the control unit 35 receives a submergence detection signal from the submergence detection unit 6, the power supply control unit 353 outputs a stop signal to the power supply 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 reliably prevented that an excessive current flows between the 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 ended, the switch 335 may be turned off to end the process shown in FIG. . In that case, unless the user performs an operation to turn on the switch 335 again after the power supply from the power supply device 33 to the electrodes 170 to 200 is stopped due to the output of the submergence detection signal, the power supply device 33 is used. From electrode 170
Power supply to ~ 200 is not resumed. As a result, the electrodes 170-2 which are not intended by the user.
The resumption of power supply to 00 can be suitably prevented, and early discharge of the battery 31 is prevented. Also,
Of course, it is possible to configure the switch 335 to be turned off when the submerged state continues for a certain time (for example, 1 minute). Furthermore, after the power supply from the power supply device 33 to the electrodes 170 to 200 is stopped, the display of the display unit 52 is changed from the display of the output voltage of the power supply device 33 and the switching state of the operation of the oscillation circuit, and the main body 12 is submerged May be switched to a display for informing the user. Thereby, it is possible to suitably notify the user that the main body 12 is submerged.

According to the massage device 1, since a potential difference is applied between the electrodes 170 and 180 and the electrodes 190 and 200, by bringing the electrodes 170 to 200 into contact with the skin and applying electrical stimulation to the skin, Has a massage effect. When the main body of the massage device 1 is submerged, the submergence detection unit 6 detects the submergence and outputs a submergence detection signal. And
When the submergence detection signal is input to the control unit 35, the power supply control unit 353 controls the potential difference applied between the electrodes 170 to 200 by the power supply unit 3. Thus, the electrode 170
Even if the electrical resistance between .about.200 decreases excessively, it is possible to prevent an excessive current from flowing between the electrodes 170.about.200. As a result, it is possible to prevent problems such as an electric shock from the user, an excessive load applied to the electronic components in the massage device 1, and 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 addition, in this example, since the submergence detection unit 6 is provided separately from the electrodes 170 to 200, even if a conductive gel or the like is applied to the skin and used, the submergence state due to the gel is erroneous. Even when the gel is used with detection suppressed, it is easy to use.

The four electrodes 170 to 200 provided in the massage device 1 of the present example are electrically conductive rotating bodies 17.
It is formed on the surface of ~ 20. By grasping the grip portion 122 of the main body 12, each of the rotating bodies 17-2
While pressing 0 against the skin, the massage device 1 is moved in the arrow P1 (or the direction of P2) as shown in FIGS. A pair of preceding rotating bodies 17, 18 (or a pair of rotating bodies 19,
20) spreads toward the front side in the moving direction, so that the pair of preceding rotating bodies 17, 1
8 (or the pair of rotating bodies 19 and 20) rotates inward to press the skin, 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 rotators 17 and 18) rotate inward, and the rotators 19 and 20 (or the rotators 17 and 1
8) In between, the skin is picked up 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.

In addition, when the massage device 1 is moved in the Q1 direction and the Q2 direction, the above-described P
As in the case of the one direction and the P2 direction, the pair of preceding rotating bodies 17 and 19 (or the pair of rotating bodies 18 and 20) rotate inward to press the skin, and the pair of following rotating bodies 19 follows. , 20 (or the pair of rotating bodies 17 and 18) rotate inward to pick up the skin, and different massage effects can be obtained by pressing and picking up the same part of the skin.

The axial interval L1 between each pair of rotating bodies 17 and 18 and the rotating bodies 19 and 20 is smaller than the axial interval L2 between the rotating bodies 17 and 19 and the rotating bodies 18 and 20. For this reason, P1 direction or P
The massaging device 1 is moved in two directions, so that a portion with a large curvature such as an arm or ankle of the body is effectively massaged between the rotating bodies 17 and 18 and between the rotating bodies 19 and 20, respectively. be able to.

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, when the massage device 1 is used, the power feeding device 33 is operated by the power from the battery 31 mounted in the main body 12, and the electrodes 170 and 180 and the electrode 1 are operated from the power feeding device 33.
A potential difference is given between 90 and 200. Thereby, a weak electric current flows through the skin between the electrodes 170 to 200, and electrical stimulation is given. Therefore, a good massage effect can be obtained by the cooperative action of the electrical stimulation and the massage.

Further, an interval M2 between the rotating bodies 17 and 18 and the rotating bodies 19 and 20 is larger than an interval M1 between the rotating bodies 17 and 19 and the rotating bodies 18 and 20. When the power feeding device 33 is operated, the electrodes 170 and 180 of the rotating bodies 17 and 18 and the electrodes 1 of the rotating bodies 19 and 20 having a large arrangement interval are used.
A potential difference is given between 90 and 200. For this reason, since an electric current can be sent through the comparatively wide skin between the electrodes 170-200, a moderate electrical stimulation can be obtained, without an electric current flowing locally. In addition, when the power feeding device 33 is operated, the electric resistance detector 34 is operated.
Thus, when the electric resistance between the electrodes 170 to 200 is detected and the detected electric resistance is equal to or less than a predetermined value, the potential difference from the power feeding device 33 is lowered by the potential difference adjusting unit 352. 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, the electroconductivity gel with respect to skin can be improved by apply | coating the electroconductive gel containing an electroconductive material to skin, and interposing the said electroconductive gel between the electrodes 170-200 and skin. Thereby, a potential difference can be reliably given between the electrodes 170 and 180 and the 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 vicinity of the connection part 130 b with the electrodes 190 and 200 in the main body 12. 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,
While being able to suppress erroneous detection of the submerged state, the submerged state can be reliably detected even when the massage 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, its width (ie the tilt axis 1
The axial length 70a) is substantially constant.

The rotating body 17 is rotatable about an axis 131. And FIG. 11 (a)-FIG.
As shown in FIG. 1D, 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 is observed to change as the rotating body 17 rotates. . As shown in FIGS. 11 (a) and 11 (c), an inclined axis 170a is formed as an axis 131.
The side projection inclination angle θ in the state where the angle is most inclined is, for example, greater than 0 ° and 45 °.
The angle may be set as follows, preferably 5 ° to 20 °, and 10 ° in this example.

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 maximum), the axis 1
It is observed in a straight line inclined with respect to 31. When the rotating body 17 rotates, each cross-sectional outline 171 is observed to change from a straight line to a curved line gradually bulging toward the end 13b side (main body 12 side) of the support shaft 13, as shown in FIG. b) (that is, a state in which the side projection tilt angle θ is maximized by a quarter of a turn, and the axis 131 and the tilt axis 170a).
In a state of overlapping with each other), it is observed in a curved line shape swelled most toward the end portion 13b.

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 gradually bulging toward the end portion 13a side (the side opposite to the main body 12) of the support shaft 13, The state shown in FIG.
A state in which the side projection inclination angle θ is rotated by a quarter from the state in which the side projection inclination angle θ is maximized again, and the axis 1
31 and the inclined axis 170a are observed in a curved line shape swelled most toward the end 13a.

And if the rotary body 17 further rotates from the state shown in FIG.11 (d), each cross-sectional outline 1
71 is observed so as to gradually change from a curved line shape to a linear shape, and in the state rotated by a quarter from the state shown in FIG. 11D, the state shown in FIG. 13
It is observed in a straight line inclined with respect to 1. 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.

Further, on the surface of the rotator 17 of the present embodiment, the cross-sectional contour line 17 corresponding to the contour of each cross-section by a plurality of virtual planes K perpendicular to the inclined axis 170 a inclined with respect to the axis 131 of the support shaft 13.
1 is formed, and 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 continues to contact the user's skin, and the contact between the electrode 170 and the user's skin becomes a point contact. This can be suitably prevented. 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 belt-like surface 172a is inclined axis 170a (FIG. 1).
1 (a)) is a straight line in the cross section. 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. Moreover, as shown in FIG.12 (c), the strip | belt-shaped surface 1 between the adjacent cross-sectional outlines 171 is shown.
72 a may be formed in a planar shape, and a linear groove 172 c may be formed along the cross-sectional outline 171. Moreover, as shown in FIG.12 (d), the strip | belt-shaped surface 1 between the adjacent cross-sectional outlines 171 is shown.
Reference numeral 72d denotes a gently curved surface, which is smoothly connected to the adjacent belt-like surface 172d to form a substantially spherical shape as a whole of the rotating body 17, and has a cross-sectional outline 171.
A ring-shaped line may be formed on the surface of the rotating body 17 by printing using a predetermined ink.

Except for the case shown in (3), the effect of picking up the skin and the effect of loosening the skin can be improved, and the effect of picking up the skin and the effect of lifting the itchy can be brought about, thereby further improving 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 electrodes 170 to 200 can be easily brought into contact with the skin. However, when compared with the case where a plurality of belt-like surfaces 172 to 202 are formed, the rotating bodies 17 to 2 are used.
It may be difficult to understand the rotation of 0, or the effect of picking up the skin may be reduced. Furthermore, you may make it form the said some strip | belt-shaped surface in the axial direction of a rotating shaft.

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.

(Example 2)
As shown in FIG. 13, the massage device 1 according to the second embodiment includes a power supply control unit 35 according to the first embodiment.

In addition, about the component equivalent to the case of Example 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

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 massage device 1 is in a submerged state, a submergence detection signal is output from the submergence detection unit 60 to the control unit 35 as shown in FIG. 14 (step S25). ). Thereafter, the electric resistance detector 34 (see FIG. 13) causes the electrodes 170 to
The electrical resistance between 200 is detected, and the control unit 35 determines whether or not the electrical resistance is greater than or equal to a predetermined value (step S26).

If it is determined in step S26 that the electrical resistance between the electrodes 170 to 200 is not equal to or greater than the predetermined value (No in step S26), the potential difference adjusting unit 352 of the control unit 35 is connected to the power feeding device 33.
A potential difference adjustment signal is output to (step S27). When the potential difference adjustment signal is input, the power feeding device 33 reduces the amount of power supplied to the electrodes 170 to 200 and adjusts the potential difference between the electrodes 170 to 200 to be a predetermined value or less (step S28). Thereafter, step S11 (FIG. 10).
Return to Browse. Moreover, also when the control part 35 judges that the electrical resistance between the electrodes 170-200 is more than predetermined value in step S26 (Yes of step S26), step S1 is also performed.
Return to 1 (see FIG. 10).

Thereby, if it is judged that it is submerged, the potential difference between the electrodes 170 to 200 is adjusted to a predetermined value or less. As a result, an excessive current is prevented from flowing between the 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. The electrical resistance between the electrodes 170 to 200 is a predetermined value (first predetermined value), and the electrode 17
The predetermined value (second predetermined value) of the potential difference between 0 and 200 can be set to an arbitrary value.
For example, when the first predetermined value is set to a large value that is not theoretically conceivable and the second predetermined value is set to 0 V, the power supply device 33 is determined to be submerged as in the first embodiment. From electrode 170
Power supply to ~ 200 will be stopped. As in Example 1, the submerged state is maintained for a certain time (
It is of course possible to configure the switch 335 to be turned off when the operation continues (for example, 1 minute). Thereby, the early discharge of the battery 31 is prevented.

(Example 3)
As shown in FIG. 15, the massage device 1 according to the third embodiment includes a display unit 52 and a switching unit 8 as a bypass circuit 80. Further, the control unit 35 includes a power supply control unit 353 (

It is configured to be able to. A control mode for detecting a submerged state in the massage device 1 of the present example is as follows. In addition, about the component equivalent to the case of Example 1 and Example 2, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

First, steps S10 and S11 (see FIG. 10) are performed as in the first embodiment.

When it is determined that the electrical resistance is not less than or equal to the predetermined value (No in Step S12), the control unit 35 determines whether or not the power feeding device 33 is connected to the electrodes 170 to 200 in the switching unit 8 (Step S12). S35). If it is determined that they are not connected (No in step S35), the switching control unit 354 of the control unit 35 outputs a first switching signal to the switching unit 8 (step S36). When the first switching signal is input, the switching unit 8 switches to the first energization path 81 and connects the power feeding device 33 to the electrodes 170 to 200 (
Step S37). Then, it controls so that the electric power feeder 33 supplies electric power to the electrodes 170-200 (step S38). On the other hand, in step S35, the power feeding device 33 is connected to the electrodes 170-20.
Even when it is determined that it is connected to 0 (Yes in step S35), in step S38, the power feeding device 33 controls to feed power to the electrodes 170 to 200.

On the other hand, when it is determined in step S12 that the electrical resistance between the pair of submergence detection electrodes 60a and 60b is equal to or less than a predetermined value (Yes in step S12), the massage device 1 is submerged in step S14. After that, a submergence detection signal is output to the control unit 35 (step S39). And the control part 35 judges whether the electric power feeder 33 is connected to the electrodes 170-200 in the switch part 8 (step S40). If it is determined that they are not connected (No in step S40), the process returns to step S11 (see FIG. 10). On the other hand, when it is determined in step S40 that the power feeding device 33 is connected to the electrodes 170 to 200 (Yes in step S40), the switching control unit 354 of the control unit 35 sends a second switching signal to the switching unit 8. Output (step S41). When the second switching signal is input, the switching unit 8 switches from the first energization path 81 to the second energization path 82 to release the connection between the power supply apparatus 33 and the electrodes 170 to 200 and displays the power supply apparatus 33. Connect to the unit 52 (step S42). And the display part 52 electrically fed from the electric power feeder 33 displays that the massage device 1 is a submerged state (step S43).

As a result, when it is determined that the state is submerged, the power supply to the electrodes 170 to 200 is stopped and the display unit 52 is controlled to be supplied with power. As a result, when the main body 12 is submerged, the electrode 17
It is possible to prevent an excessive current from flowing between 0 and 200. Moreover, since it is displayed on the display part 52 that the massage device 1 is determined to be submerged, the user can use the electrodes 170-2.
It can be easily recognized that the current is controlled so as not to flow excessively during 00. Therefore, the massage device 1 that has been dropped into a bathtub or the like and submerged can be picked up without hesitation. Also in this example, the same operational effects as in the case of Example 1 are obtained. still,
In FIG. 16, after the process of step S43 is completed, the process returns to step S11 (FIG. 10). However, after the process of step S43 is completed, the process shown in FIG. 16 may be terminated. In that case, the power supply from the power supply device 33 to the electrodes 170 to 200 is not resumed unless an instruction operation is performed by the user. Thereby, resumption of the electric power feeding to the electrodes 170 to 200 not intended by the user can be suitably prevented. It is of course possible to configure the switch 335 to be turned off when the submergence detection state continues for a certain period of time.
