Description

  The present invention relates to a massager adapted to obtain a massage effect by electrical stimulation.

Conventionally, as this type of massage device, 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 be attached to skin such as a face. A stimulation generator is connected to both electrodes via a lead. Then, in a state where the pad is attached to the skin such as the face, a pulse signal is applied from the stimulation generator to both electrodes, whereby the skin is electrically stimulated to promote blood circulation. ing.

  Further, in the conventional configuration described in Patent Document 2, two rollers are supported by the case so as to be rotatable about an axis extending in parallel at intervals. At both ends of each roller, a pair of electrode roller portions is provided via an intermediate insulating roller portion. A pair of endless conductive sheets are wound around an electrode roller portion facing each other between both rollers. Then, while both endless conductive sheets are circularly moved in a state of being in contact with the skin, positive and negative different potentials are applied to the both endless conductive sheets via the electrode roller portion. As a result, current flows in the skin between the two endless conductive sheets, so that the skin can be electrically stimulated.

JP 2005-245585 A Unexamined-Japanese-Patent No. 11-164895

  However, in the configurations described in Patent Document 1 and Patent Document 2, when the massage device is submerged, etc., the electrical resistance between the pair of electrodes to which the potential difference is applied is excessively reduced to cause excess between the pair of electrodes. Current may flow in the In this case, if the user touches the massager or the water being energized, an electric shock may occur, or the electronic components in the massager may be overloaded, causing a failure, or waste a large amount of power. Cause problems such as consumption. Therefore, when using in a bathroom or the like where the massage device may be submerged, it is inconvenient because care is required to avoid the above-mentioned problems.

  Also, in order to suppress excessive current flow between the pair of electrodes, it is determined that the circuit is in a submerged state when the electrical resistance between the pair of electrodes becomes equal to or less than a predetermined value, and the pair of electrodes is It is conceivable to stop power feeding, for example. 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 used in a state where 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 through the said gel, and the electrical resistance between a pair of said electrodes becomes temporarily below in predetermined value. Then, as described above, when the electric resistance between the pair of electrodes becomes equal to or less than a predetermined value, it is determined that the water is submerged and power supply to the pair of electrodes is stopped. At times, it may be mistakenly determined that the water is submerged, and the feeding may be stopped unexpectedly. Therefore, it is not easy to use when using conductive gel.

  The present invention has been made in view of the above background, and can provide electrical stimulation to the skin to obtain a good massage effect, and can suppress occurrence of problems due to water immersion, and provide a convenient-use massager. It is.

One aspect of the present invention is a body,
Rutotomoni provided so as to be exposed to the outside of the body, and at least two electrodes for stimulation configured to abut against the human body to impart electrical stimulation,
A feed unit for applying a potential difference between the at least two stimulation electrodes;
A submersion detection unit which outputs a submersion detection signal for detecting submersion of the main body and / or the electrode for stimulation ;
A control unit that controls the potential difference applied by the power supply unit when the submersion detection signal is input;
Equipped with
The submergence detector is in the massager according to claim Rukoto to have a disposed a submerged detection electrodes between the at least two stimulation electrodes.

  According to the massager, since a potential difference is applied between at least two electrodes, the electrodes are brought into contact with the skin to exert a massage effect by applying electrical stimulation to the skin. And when the main body and / or the electrode of the massage device are submerged, the submersion detecting unit detects the submersion and outputs a submersion detection signal. Then, when the submersion detection signal is input to the control unit, the control unit controls the potential difference applied between the electrodes by the power supply unit. Thereby, even if the electrical resistance between the electrodes is excessively reduced due to the water immersion, excessive current flow can be suppressed between the electrodes. As a result, it is possible to prevent problems such as an electric shock by the user, an excessive load on electronic parts in the massage device, and wasteful consumption of a large amount of power. Therefore, there is no need to pay special attention when using in a place where there is a risk of being submerged, such as a bathroom, and the usability is good.

  In addition, since a submersion detection unit is provided separately from the electrodes, even when a conductive gel or the like is applied to the skin and used, erroneous detection of a submersion state due to the gel is suppressed, and the gel is prevented. It is easy to use even when using.

  As described above, according to the present invention, it is possible to provide an electrical stimulation to the skin to obtain a good massage effect, and to suppress occurrence of a problem due to submersion, thereby providing a user-friendly massage device.

  The control unit may include a feed control unit that controls power supply to the feed unit, and the feed control unit may control the feed unit to stop power supply when the submersion detection signal is input. It can be done. In this case, when the main body or the electrode is submerged, the power supply to the power feeding unit is stopped, so that an excessive current can be reliably prevented from flowing between the electrodes.

  The control unit further includes an electric potential difference adjustment unit that adjusts the electric potential difference, and the electric resistance detection unit detects the electric immersion detection signal when the water immersion detection signal is input. When the electric resistance is equal to or less than a first predetermined value, the electric potential difference adjustment unit may control to adjust the electric potential difference to a second predetermined value or less. In this case, when the main body or the electrode is submerged, the potential difference between the electrodes is prevented from becoming a predetermined value or more. As a result, an excess current can be effectively prevented from flowing between the electrodes. Note that the first predetermined value of the electrical 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, current can be prevented from flowing between the electrodes when the submersion detection signal is input.

  A first conduction path connecting the feeding portion and the electrode between the feeding portion and the electrode; and a second conduction path connecting a bypass circuit bypassing the feeding portion and the electrode; A switching unit for switching the switching unit, and the control unit causes the switching unit to switch from the first current path to the second current path to bypass the electrode when the submersion detection signal is input. It is possible to control the department. Thereby, when the main body or the electrode is submerged, the electrode can be bypassed by connecting the power supply unit and the bypass circuit. As a result, excessive current can be reliably prevented from flowing between the electrodes. As a bypass circuit, the circuit for display parts which controls lighting of the LED lamp which displays the operation state of a massage machine, etc. can be mentioned, for example. In the case of adopting the display circuit as the bypass circuit, when the power for the display circuit is supplied to the display circuit through the bypass circuit, the lighting state of the LED lamp indicates a state of being submerged (for example, a lighting state) The user may be notified that the submersion has been detected by controlling the LED lamp to blink at high speed or the like.

  The main body can be grasped, and the water immersion detection unit can be provided on the surface of the main body on which the electrode is exposed. In this case, it is possible to prevent the hand from touching the submersion detection unit when gripping the main body. Thereby, while being able to suppress the misdetection of a submersion state, even when the said massage device is submersed in the state which hold | gripped the main body, a submersion state can be detected reliably.

  The submersion detecting unit may be provided in the vicinity of a connecting portion between the main body and the electrode. In this case, for example, even when the main body is shaped as shown in FIG. 17 and FIG. 18, when the main body is gripped, it is possible to prevent the hand from touching the submersion detection unit. Thereby, while being able to suppress the misdetection of a submersion state, even when the said massage device is submersed in the state which hold | gripped the main body, a submersion state can be detected reliably.

  The electrode may be constituted by at least two rotating bodies made of a conductor rotatably supported around an axis radially extending from the main body. In this case, the rotating body forming the electrode can exert the pick-up effect on the skin and the rejuvenation effect, thereby further improving the massage effect.

  The rotating body may be in the shape of a sphere, an oval sphere, or a combination thereof. In this case, since the rotating body can be smoothly rotated in a state where the rotating body is in contact with the skin, the operability is good and the feeling of use is excellent. In addition, it is possible to more effectively exert the skin pick-up effect and the acupuncture effect, and the massage effect can be further improved. In the present specification, the term "spherical" and "elliptical sphere" are not limited to strictly spherical and elliptical spheres, but generally spherical shapes such as shapes in which spherical and elliptical spheres are generally recognized, and shapes having some irregularities on the surface Shall be included.

  A cross-sectional outline corresponding to the outline of each cross section in a plurality of virtual planes perpendicular to the inclined axis line inclined with respect to the axis can be formed on the surface of the rotating body. In this case, when the rotating body is rotated, the shape of the cross-sectional contour is periodically changed and observed according to the rotation, so that it is possible to easily recognize that the rotating body is rotating.

  A plurality of annular belt-like surfaces are arranged in the axial direction of the inclined axis on the surface of the rotating body, and the cross-sectional outline is formed so as to be visible as a boundary between the adjacent belt-like surfaces. Can be In this case, since the cross-sectional contours as the boundary lines are periodically changed and observed according to the rotation angle of the rotating body, it is possible to easily recognize that the rotating body is rotating. . Furthermore, since the plurality of belt-shaped surfaces are arranged in the axial direction of the inclined axis, the direction of the belt-shaped surface periodically changes according to the rotation of the rotating body, so that the skin is picked up between the pair of rotating bodies Strength and weakness will be given to the effect and the repelling effect. As a result, while being able to improve a massage effect further, a user can be made to recognize effectively the pick-up effect of a skin, and the wrinkles and hoofing effect, and an excellent feeling of use can be obtained.

  The band-shaped surface formed in the annular shape has a shape different from that of the other band-shaped surface adjacent to the band-shaped surface so that the boundary line with the other band-shaped surface adjacent in the axial direction of the inclined axis is easily visible. preferable. For example, it is possible to make the shape of the strip surface and the other strip surfaces adjacent thereto in the cross section including the tilt axis straight, and to make the tilt angles of the both different from the tilt axis. Moreover, while making the shape of the said strip | belt-shaped surface in the cross section containing an inclination-axis line into linear form, the curved shape which expanded the shape of the other strip-shaped surface adjacent to this outside the rotary body or depressed inside the rotary body It can be done. Moreover, the shape of the said strip surface in the cross section containing an inclination-axis line and the other strip surface adjacent to this can be made into the curve shape hollowed inside the rotary body. In these cases, the boundary line (cross-sectional outline) of the band-shaped surface and the other band-shaped surface adjacent to the band-shaped surface can be clearly formed in a linear shape.

  The power supply unit includes: a power supply unit including power supplied to the power supply unit; and an operation unit configured to be capable of changing the control mode of the control unit, wherein the power supply unit is accommodated in the main body It is preferable to be configured to be in contact with the human body to apply an electrical stimulation. In this case, since the power supply is housed in the main body, it is not necessary to supply power from the outside, so that it can be wireless. Therefore, it is easy to use and can be used in places without an external power supply.

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

  The plurality of electrodes are formed on a sheet-like base material extended from the main body, and the base material electrically connects the electrodes and the power supply through the control unit and the power feeding unit. Can be formed. In this case, since the electrode is integrally formed with the main body and has a sheet shape, the electrode is easily attached to the skin together with the main body. This makes the massage device easy to use.

Further, the control unit 35 measures the elapsed time from the start of operation of the power feeding device 33 by the switch 335, and reduces the output from the power feeding device 33 for power saving when a predetermined time (for example, 10 minutes) has elapsed. Alternatively, a timer unit 351 (see FIG. 9) for stopping the supply is provided. As a result, the power feeding device 33 is prevented from operating for a long time, and early discharge of the battery 31 is prevented.

  The power supply device 33 is connected to an oscillation circuit (not shown), and is configured to be supplied with three types of pulse voltages having different waveforms by the operation of the oscillation circuit. The output voltage of the power feeding device 33 can be switched by the switch 335, and the operation of the oscillation circuit can be switched by the switch 336.

The lip portion 214b is in sliding contact with the outer peripheral surface of the support shaft 13, and oil seal grease is interposed as a lubricant between the two, and the space between the both is sealed.

  A ball bearing type annular bearing 215 is disposed on the roller fixing ring 213 on the opposite side to the flange portion 213 b. The inner diameter of the bearing 215 matches the outer diameter of the support shaft 13, and the support shaft 13 is inserted through the bearing 215. The outer diameter of the bearing 215 is larger than the inner diameter of the cylindrical portion 213a of the roller fixing ring 213, and the bearing 215 is in contact with the edge of the cylindrical portion 213a on the opposite side of the flange portion 213b. Further, a groove 13d is formed on the outer peripheral surface near the center of the support shaft 13, and the E-ring 216 is engaged with the groove 13d. The bearing 215 is sandwiched from the edge of the cylindrical portion 213a, the E-ring 216, and both sides in the axial direction of the support shaft 13, and is prevented from coming off.

  As shown in FIG. 5, the connection fitting 217 is attached to the bearing 215. The connector fitting 217 extends along the outer circumferential surface of the bearing 215 from the annular main body portion 217 a along the outer circumferential surface of the bearing 215 and engages with the other axial end surface of the bearing 215. The two engaging claws 217 b, one guide claw 217 c extending from the annular main body portion 217 a to the axial center of the outer peripheral surface along the outer peripheral surface of the bearing 215, and the bearing 215 protruding opposite to the support shaft 13. It has a connection protrusion 217 d that inclines to the axial center side. The two engaging claws 217 b and one guide claw 217 c are formed at equal intervals in the circumferential direction (that is, at 120 ° intervals around the axial center of the support shaft 13). The connection fitting 217 engages the guide claws 217 c with the outer peripheral surface of the bearing 215 and engages the engagement claws 217 b with the other end surface in the axial direction along the outer peripheral surface of the bearing 215 so that the annular main body 217 a It is disposed along one end face in the axial direction of Then, as shown in FIG. 6, the tip end of the connection protrusion 217 d is in sliding contact with the outer peripheral surface of the support shaft 13. Thus, the connection fitting 217 and the support shaft 13 can be energized.

  As shown in FIGS. 5 and 6, the rotating body 17 is attached to an end 13 a of the support shaft 13 opposite to the main body 12 (see FIG. 2). The rotating body 17 has an outer roller 210, a roller core 211 forming the inside of the outer roller 210, and a roller cap 212 covering the end 13a of the support shaft 13 inside the outer roller 210. As shown in FIG. 6, the outer roller 210 forms an outer peripheral surface of the rotating body 17 and also forms an inner cylindrical portion 210 a in a cylindrical shape inside the rotating body 17. An O-ring 213d is interposed between the inner cylindrical portion 210a and the roller fixing ring 213, and the space between them is sealed. Conductive plating (in this example, chromium plating) is formed on the surface of the outer roller 210 as the electrode 170. The annular main body portion 217 a, the engagement claws 217 b and the guide claws 217 c of the connection fitting 217 are in contact with the surface of the inner cylindrical portion 210 a which is a part of the outer roller 210. Thus, the connection fitting 217 and the conductive plating (electrode 170) of the outer roller 210 can be energized.

  As shown in FIGS. 5 and 6, four holes 213g through which the screws 213e are inserted are formed in the collar portion 213b of the roller fixing ring 213. Then, the screw 213e is inserted through the hole 213g, and the cylindrical portion 213a of the roller fixing ring 213 is accommodated in the inner cylindrical portion 210a of the outer roller 210 through the screw 213e inserted through the hole 213g. The roller fixing ring 213 is attached to the inside of the rotating body 17. And the output harness 339 is attached to the edge part 13b by the side of the main body 12 (refer FIG. 2) in the support shaft 13 via the screw 13e. The support shaft 13 is made of a conductive metal (in this example, a stainless steel alloy), and the output harness 339 and the support shaft 13 can be energized.

  The end 13b of the support shaft 13 on the side of the main body 12 (see FIG. 2) is inserted into a through hole 128d provided on the lower surface cover 128 and provided on the lower side 124 of the main body as shown in FIG. The support hole 124d is inserted. The support hole 124d has a D-shape along the outer shape of the enlarged diameter portion 13c, and the enlarged diameter portion 13c of the support shaft 13 is located in the support hole 124d. Thus, the rotation of the support shaft 13 is prevented. At the end 13 b located in the main body 12, a retaining E ring 218 is attached. An O-ring 219 inserted through the support shaft 13 intervenes between the support shaft 13 and the wall surface of the support hole 128d to seal between the two.

  The other rotating bodies 18 to 20 are also attached to the main body 12 through the support shafts 14 to 16 in the same manner as the rotating body 17. Thereby, as shown in FIG. 2, the rotating bodies 17 and 18 are connected to the connecting portion 130 a of the lower surface of the main body 12, and the rotating bodies 19 and 20 are connected to the connecting portion 130 b of the lower surface of the main body 12. There is. In addition, the support shafts 13 to 16 are arranged such that the rotary bodies 17 to 20 are positioned on an inclined line extending radially from the top to the bottom of the main body 12.

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

  As shown in FIG. 8, the angle α between the p axis 131 of the support shaft 13 and the axis 141 of the support shaft 14 in a cross section parallel to the support shaft 13 and the support shaft 14 is preferably 60 ° to 80 °. 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 between the support shaft 15 and the support shaft 16 is also the same as the angle α between 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 rotating body 17 and the center of the rotating body 18 overlap, an imaginary line T perpendicular to the plane U with which all the rotating bodies 17 to 20 are in contact The angles β of the axes 13 and 14 with the axes 131 and 141 are each 30 °. The angle γ between the imaginary line T and the axes 151 and 161 of the support shafts 15 and 16 is also 30 ° when viewed from the direction in which the center of the rotor 19 and the center of the rotor 20 overlap.

  The diameter of each of the rotating bodies 17 to 20 is preferably 38 to 45 mm, and more preferably 40 mm. The size of the diameter of each of the rotating bodies 17 to 20 may be all the same, or a part of the diameter may be different from the other diameter.

  The distance between the outer surface (electrode 170) of the rotating body 17 and the outer surface (electrode 180) of the rotating body 18 shown in FIG. 2 (that is, the distance between the rotating body 17 and the rotating body 18) M1 The distance between the surface (electrode 170) and the outer surface (electrode 190) of the rotating body 19 (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 preferably 14 mm to 40 mm, and more preferably 39.5 mm. The distance between the rotating body 19 and the rotating body 20 is the same as the distance M1. Moreover, the space | interval of the rotary body 18 and the rotary body 20 is the same as the said space | interval M2.

  When using the massaging device 1 of this embodiment, when 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 massaged. Furthermore, the outer surfaces of the rotating bodies 17 to 20 form electrodes 170 to 200, and the power supply device 33 is operated by the power from the battery 31 mounted in the main body 12, and from the power supply device 33 to the electrodes 170, A potential difference is provided between 180 and the electrodes 190,200. Then, when the electrodes 170 to 200 are in contact with the skin, a weak current flows in the skin between the electrodes 170 to 200, and an electrical stimulation is given to the skin. As a result, a good massage effect can be obtained by the joint action of the electrical stimulation and the above-mentioned kneading and loosening by the rotation of the rotating bodies 17 to 20.

  The potential difference generated between the electrodes 170 and 180 and the electrodes 190 and 200 can be set as appropriate. However, if the potential difference is too large, it is not preferable because the electrical stimulation to the skin is excessive and the user may feel pain. In addition, when the potential difference is too small, it is not preferable because the user is difficult to obtain the sensation of feeling to the electrical stimulation. For example, the potential difference can be set such 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, since the contact portion between the two is very narrow, the weak current flowing between the two concentrates on the narrow contact portion, causing the user to receive excessive electricity. May cause irritation. In order to avoid this, when the rotating bodies 17 to 20 come in contact with the skin, that is, the electric resistance detection unit 34 for detecting the electric resistance between the electrodes 170 to 200 changes the electric resistance to a predetermined value or less When the contact between the rotating bodies 17 to 20 and the skin is detected, the potential difference adjustment unit 352 gradually increases the weak current between them from a low value, even if so-called slow start control is performed. Good.

Next, a control mode for detecting a submerged state in the massager 1 will be described in detail below.
As shown in FIG. 10, first, the switch 335 is turned on (step S10). Thereafter, the electrical resistance between the pair of submersion detection electrodes 60a and 60b (see FIG. 2) in the submersion sensor 60 is detected (step S11). Then, the submersion detection unit 6 determines whether the electrical resistance of the pair of submersion detection electrodes 60a and 60b is less than or equal to a predetermined value (step S12). If the submersion detection unit 6 determines that the electrical resistance is not equal to or less than the predetermined value (No in step S12), the power supply device 33 supplies power to the electrodes 170 to 200 according to the control instruction of the control unit 35 (power supply control unit 353) Step 13). Thereafter, the process returns to step S11.

  In step S12, when the submersion detecting unit 6 determines that the electrical resistance is equal to or less than the predetermined value (Yes in step S12), the massaging device 1 is determined to be submersed (step S14), and the submersion detecting unit 6 A submersion detection signal is output to the control unit 35 (step S15). Then, the control unit 35 determines whether the power feeding device 33 feeds power to the electrodes 170 to 200 (step S16). When it is determined that the power feeding device 33 does not feed 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). Then, the power feeding device 33 stops the power feeding to the electrodes 170 to 200 (step S18). Thereafter, the process returns to step S11. When the control unit 35 receives a submersion detection signal from the submersion detection unit 6, the power supply control unit 353 outputs a stop signal to the power supply apparatus 33 without performing the determination process of step S16. Also good.

  As a result, when it is determined that the apparatus is submerged, power supply to the rotating bodies 17 to 20 is controlled to be stopped. As a result, excessive flow of current between the electrodes 170 and 200 can be reliably prevented when the main body 12 is submerged. Although the process is returned to step S11 after the process of step S18 in FIG. 10, the switch 335 may be turned off after the process of step S18 and the process shown in FIG. 10 may be completed. . In that case, after the power feeding from the power feeding device 33 to the electrodes 170 to 200 is stopped by outputting the submersion detection signal, the power feeding device 33 is operated unless the user turns on the switch 335 again. Power supply to the electrodes 170 to 200 is not resumed. Thereby, resumption of power feeding to the electrodes 170 to 200 which the user does not intend can be suitably prevented, and early discharge of the battery 31 is prevented. It is of course possible to turn off the switch 335 when the submersion state continues for a fixed time (for example, one minute). Furthermore, after the power supply from the power supply device 33 to the electrodes 170 to 200 is stopped, the display unit 52 is submerged from the display of the output voltage of the power supply device 33 and the display of the switching state of the operation of the oscillation circuit. May be switched to a display for informing the user. This makes it possible to preferably notify the user that the main body 12 is submerged.

  According to the massager 1, since a potential difference is applied between the electrodes 170 and 180 and the electrodes 190 and 200, the electrodes 170 to 200 are brought into contact with the skin to give electrical stimulation to the skin, Play a massage effect. When the main body of the massage device 1 is submerged, the submersion detecting unit 6 detects the submersion and outputs a submersion detection signal. Then, the submersion detection signal is input to the control unit 35, whereby the power supply control unit 353 controls the potential difference applied between the electrodes 170 to 200 by the power supply unit 3. Thereby, even if the electrical resistance between the electrodes 170 and 200 is excessively reduced, excessive current flow can be suppressed between the electrodes 170 and 200. As a result, it is possible to prevent problems such as an electric shock by the user, an excessive load on electronic parts in the massage device 1, and wasteful consumption of a large amount of power. Therefore, there is no need to pay special attention when using in a place where there is a risk of being submerged, such as a bathroom, and the usability is good.

  Further, in the present example, since the submersion detection unit 6 is provided separately from the electrodes 170 to 200, even when a conductive gel or the like is applied to the skin and used, the submersion error due to the gel is erroneous Detection is suppressed, and it is convenient to use even when using the gel.

  The four electrodes 170 to 200 provided in the massager 1 of this example are formed on the surfaces of the conductive rotating bodies 17 to 20. While holding the grips 122 of the main body 12 and pressing the rotating bodies 17 to 20 against the skin, the massager 1 is moved in the direction of the arrow P1 (or in the direction of P2) as shown in FIGS. Since the preceding pair of rotating bodies 17 and 18 (or the pair of rotating bodies 19 and 20) spread toward the front side in the moving direction, the preceding pair of rotating bodies 17 and 18 (or the pair of rotating bodies 19 20) rotates inward to press the skin, and a massage effect is exerted. On the other hand, since the pair of rotating bodies 19 and 20 (or pair of rotating bodies 17 and 18) which follow is spread toward the rear side in the moving direction, the pair of rotating bodies 19 and 20 (or pair of The rotating bodies 17 and 18) rotate inward, and the skin is picked up between the rotating bodies 19 and 20 (or both rotating bodies 17 and 18), and a massage effect is exhibited. That is, by moving the main body 12 in one direction (P1 direction or P2 direction), different massage effects of pressing and picking can be obtained on the same part of the skin.

  Further, even when the massager 1 is moved in the Q1 direction and the Q2 direction, the pair of preceding rotating bodies 17, 19 (or the pair of rotating bodies 18, 20) as in the case of the P1 direction and the P2 direction described above. ) Rotates inward to press the skin, and a pair of rotating bodies 19 and 20 (or a pair of rotating bodies 17 and 18) rotating backward is picked up and the skin is picked up, and the same part of the skin The different massage effects of pressing and picking up can be obtained.

  The axial distance L1 between the rotary members 17 and 18 and the rotary members 19 and 20 in each pair is smaller than the axial distance L2 between the rotary members 17 and 19 and the rotary members 18 and 20. For this reason, by moving the massager 1 in the P1 direction or the P2 direction, portions with large and narrow curvatures, such as the arms and ankles of the body, between the rotating bodies 17 and 18 and between the rotating bodies 19 and 20, respectively. , Can be effectively massaged.

  The rotating bodies 17 to 20 have a spherical shape. Thereby, the rotating bodies 17 to 20 can be smoothly rotated in a state where the rotating bodies 17 to 20 are in contact with the skin, and the feeling of use is excellent. In addition, it is possible to exert the effect of picking up the skin and the effect of cleansing and it is possible to further improve the massage effect. Of course, the rotary bodies 17 to 20 may be formed into an elliptical sphere, or a combination of a spherical and an elliptical sphere, or the like.

  Furthermore, when the massager 1 is used, the power supply device 33 is operated by the power from the battery 31 mounted in the main body 12, and a potential difference between the electrodes 170 and 180 and the electrodes 190 and 200 is generated from the power supply device 33. Given. Thereby, a weak current flows in the skin between the electrodes 170-200 to give an electrical stimulation. Therefore, a good massage effect can be obtained by the combined action of the electrical stimulation and the soothing massage.

  Further, the distance M2 between the rotating bodies 17 and 18 and the rotating bodies 19 and 20 is larger than the distance M1 between the rotating bodies 17 and 19 and the rotating bodies 18 and 20. Then, at the time of operation of the above-described power feeding device 33, a potential difference is applied between the electrodes 170, 180 of the rotating members 17, 18 having a large arrangement interval and the electrodes 190, 200 of the rotating members 19, 20. For this reason, since an electric current can be sent to the comparatively wide skin between the electrodes 170-200, a moderate electrical stimulation can be obtained, without an electric current flowing locally. Moreover, when the power feeding device 33 operates, the electric resistance detection unit 34 detects the electric resistance between the electrodes 170 to 200, and the electric potential difference adjustment unit 352 feeds the power feeding device when the detected electric resistance is less than a predetermined value. The potential difference from 33 is reduced. For this reason, for example, even in the case where the electrical resistance is small, such as when the skin is wet, the current does not flow too much to the skin and there is no possibility that the strong electrical stimulation is given.

  Furthermore, the conductivity with respect to the skin can be enhanced by applying a conductive gel containing a conductive material to the skin and interposing the conductive gel between the electrodes 170-200 and the skin. As a result, a potential difference can be reliably provided between the electrodes 170 and 180 and the electrodes 190 and 200 to effectively provide electrical stimulation to the skin. In particular, even when the skin is in a dry state, electrical stimulation can be effectively applied to the skin. The type of conductive gel to be used is not particularly limited, and known ones can be used. For example, a conductive gel that produces a slimming effect can be used. Thus, in addition to the massage effect and the electrical stimulation, a slimming effect can be exhibited.

  In the present example, the submersion detecting unit 6 is provided in the main body 12. Thereby, when the conductive gel is applied to the skin and used, the gel is prevented from interfering with the submersion detecting unit 6, and thus the erroneous detection of the submersed state by the gel is further suppressed. Therefore, the usability in the case of using the gel is further improved.

  In the present example, the main body 12 is grippable, and the submersion detection unit 6 is provided in the main body 12 in the vicinity of the connection portion 130 b with the electrodes 190 and 200. Thereby, when the main body 12 (gripping part 122) is gripped, it can suppress that a hand touches the submersion detection part 6. As a result, while being able to suppress the misdetection of a submersion state, even when the massage device 1 is submersed in the state which hold | gripped the main body 12 (grip part 122), a submersion state can be detected reliably.

  As shown in FIG. 11A, on the surface of the rotating body 17, a cross-sectional contour corresponding to the contour of each cross section 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. And between the cross-sectional outline 171 adjacent to each other, a band-like surface 172 formed in an annular shape is formed. Each belt-like surface 172 is gently recessed inside the rotating body 17. Therefore, each band-shaped surface 172 is arranged in the axial direction of the inclined axis 170 a, and the cross-sectional outline 171 is formed so as to be visible as a boundary between adjacent band-shaped surfaces 172. The width of each belt-like surface 172 (that is, the length in the axial direction of the inclined axis 170a) is substantially constant.

  The rotating body 17 is rotatable about an axis 131. Then, as shown in FIGS. 11A to 11D, the side projection inclination angle θ of the inclination axis line 170 a with respect to the axis line 131 when viewed from the direction perpendicular to the axis line 131 corresponds to the rotation of the rotating body 17. It is observed to change with it. As shown in FIGS. 11A and 11C, the side projection inclination angle θ in the state where the inclination axis 170a is most inclined to the axis 131 is, for example, larger than 0 ° and 45 ° or less. Preferably, it is 5 degrees-20 degrees, and is 10 degrees in this example.

  In addition, when viewed in a direction perpendicular to the axis 131, each cross-sectional outline 171 is repeatedly observed as being linear and curved as the rotating body 17 rotates. Specifically, in the state shown in FIG. 11A (that is, in the state in which the side projection inclination angle θ is maximum), it is observed in a straight line inclined with respect to the axis 131. Then, when the rotating body 17 rotates, it is observed that each cross-sectional outline 171 gradually changes from a linear shape to a curved linear shape that bulges toward the end 13 b side (the main body 12 side) of the support shaft 13. b) toward the end 13b in the state shown in b) (that is, a state in which the axis 131 and the inclined axis 170a overlap each other by a quarter of a rotation from the state in which the side projection inclination angle θ is maximum). It is observed as the most bulging curved line.

  Thereafter, when the rotating body 17 is further rotated, each cross-sectional outline 171 is observed to gradually change from a curved line to a linear shape, and the state shown in FIG. 11C (ie, the axis 131 and the inclined axis 170a In the state where the side projection inclination angle θ becomes maximum again) in the direction opposite to the inclination direction shown in FIG. It is observed in an inclined straight line. Thereafter, when the rotating body 17 is further rotated, it is observed that each cross-sectional contour 171 gradually changes from a straight line into a curved line that bulges toward the end 13a side of the support shaft 13 (opposite to the main body 12) In the state shown in FIG. 11D (that is, a state where the side projection inclination angle θ is once again rotated by 1⁄4 from the state where the side projection inclination angle θ is maximum again, and the axis 131 and the inclination axis 170a overlap) It is observed in the form of the most bulging curved line on the end 13a side.

  Then, when the rotor 17 is further rotated from the state shown in FIG. 11 (d), each cross-sectional outline 171 is observed to gradually change from a curved line to a linear shape, and from the state shown in FIG. 11 (d) In the state of one quarter rotation, the state shown in FIG. 11 (a) described above is obtained, and observed again in the form of a straight line inclined with respect to the axis 131. As shown in FIG. 2, cross-sectional outlines 181, 191, 201 similar to the cross-sectional outline 171 are also formed on the rotating bodies 18, 19, 20, and cross-sectional outlines 182, 192 similar to the strip surface 172, 202 is formed. It rotates similarly in the aspect similar to the rotary body 17, and is observed similarly.

  As described above, since the cross-sectional contour line 171 is repeatedly observed in a linear shape and a curved linear shape along with the rotation of the rotating bodies 17 to 20, the user easily visually recognizes the rotation of the rotating bodies 17 to 20. be able to. Furthermore, since the belt-like surfaces 172 to 202 of the rotating bodies 17 to 20 are formed as described above, compared with the case where the belt-like surfaces 172 to 202 are not formed (when the rotors 17 to 20 are smooth). Can improve the skin pick-up effect and the soothing effect. In addition to this, the contact state between the rotating bodies 17 to 20 and the skin changes in accordance with the rotation angle of the rotating bodies 17 to 20, so some slightness in the skin picking up effect and the skin loosening effect is also possible. Contribute to a further improvement of the feeling of use.

  Further, on the surface of the rotating body 17 of the present embodiment, a plurality of cross-sectional outlines 171 corresponding to the contours of the respective cross sections by the plurality of virtual planes K perpendicular to the inclined axis 170a inclined with respect to the axis 131 of the support shaft 13 Between the cross-sectional contours 171 which are formed and adjacent to each other, a band-shaped surface 172 formed in an annular shape is formed. As compared with the case where the cross-sectional outline 171 is formed in the same direction as the axis 131, the belt-like surface continues to be in contact with the user's skin, and the contact between the electrode 170 and the user's skin becomes point contact. Can be suitably prevented. This makes it possible to give the user a continuously stable electrical stimulation.

  In the present embodiment, the plurality of belt-like surfaces 172 to 202 are formed so as to be gently recessed inside the rotating bodies 17 to 20. However, instead of this, the shapes shown in FIGS. 12 (a) to 12 (d) It can also be done. Specifically, as shown in FIG. 12A, the strip-like surface 172a between the adjacent cross-sectional outlines 171 may be formed in a planar shape. The belt-like surface 172a is linear in the cross section including the inclined axis 170a (see FIG. 11A). Further, as shown in FIG. 12B, the strip-like surface 172a between adjacent cross-sectional outlines 171 is formed in a planar shape, and the strip-like surface 172b located next to the strip-like surface 172a is outside the rotating body 17. It can be in a bulging shape. Further, as shown in FIG. 12C, the strip-like surface 172a between the adjacent cross-sectional outlines 171 may be formed in a planar shape, and the linear grooves 172c may be formed along the cross-sectional outline 171. Further, as shown in FIG. 12 (d), the belt-like surface 172d between adjacent cross-sectional outlines 171 is a gently curved surface, and is smoothly connected to the adjacent belt-like surface 172d. As a whole, a substantially spherical shape may be formed, and an annular line may be formed on the surface of the rotary body 17 by printing using a predetermined ink along the cross-sectional contour 171.

  In any of the above cases, as the cross-sectional contour line 171 is repeatedly observed in a linear shape and a curved linear shape as the rotating bodies 17 to 20 rotate, the user rotates the rotating bodies 17 to 20. It can be easily viewed. In addition, except for the case shown in FIG. 12 (d) where the cross-sectional outline 171 is formed by printing, it is possible to improve the skin pick-up effect and the skin loosening effect, and also the skin pick-up effect and the skin loosening effect. This can further improve the feeling of use.

  Moreover, it may change to said several strip | belt-shaped surface 172-202, and may form a spiral groove. Moreover, you may embed the material different from the formation material of the rotary bodies 17-20 along the one part strip | belt-shaped surface 172-202 among several said strip-shaped surfaces 172-202. For example, a germanium alloy or a titanium alloy can be adopted as a material to be embedded.

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

  Furthermore, in place of the plurality of strip surfaces 172 to 202, a diamond cut may be formed by combining many triangular facets. In addition, it is possible to form a satin finish consisting of fine irregularities or to form a minute projection having a conical shape or a cylindrical shape on part or all of the surfaces of the rotary bodies 17 to 20. In these cases, as compared with the case where the rotating bodies 17 to 20 have smooth surfaces, it is possible to improve the skin picking-up effect and the skin-removing effect.

  The central axis of at least one of the rotating bodies 17 to 20 may be decentered with respect to the axis of the support shafts 13 to 16. In this case, since the rotary bodies 17 to 20 having the central axis eccentrically rotate eccentrically rotate, it is possible to make the contact pressure with the skin strong or weak.

  As described above, according to this example, it is possible to give an electrical stimulation to the skin to obtain a good massage effect, and to suppress the occurrence of a problem due to submersion, thereby providing the easy-to-use massage device 1 .

(Example 2)
As shown in FIG. 13, the massager 1 according to the second embodiment does not include the power supply control unit 353 (see FIG. 9) according to the first embodiment. And in this example, the control mode for detecting the submersion state in massager 1 is made as follows. 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 the submersion state, a submersion detection signal is output from the submersion detection unit 60 to the control unit 35 as shown in FIG. 14 (step S25). ). Thereafter, the electric resistance detection unit 34 (see FIG. 13) detects the electric resistance between the electrodes 170 to 200, and the control unit 35 determines whether the electric resistance is equal to or more than a predetermined value (step S26).

  If it is determined in step S26 that the electrical resistance between the electrodes 170 and 200 is not greater than or equal to the predetermined value (No in step S26), the potential difference adjustment unit 352 of the control unit 35 outputs a potential difference adjustment signal to the power feeding device 33 (step S27). When the potential difference adjustment signal is input, the power supply device 33 reduces the amount of power supplied to the electrodes 170 to 200 so that the potential difference between the electrodes 170 to 200 becomes equal to or less than a predetermined value (step S28). Thereafter, the process returns to step S11 (see FIG. 10). In addition, in step S26, when the control unit 35 determines that the electrical resistance between the electrodes 170 and 200 is equal to or more than a predetermined value (Yes in step S26), the process also returns to step S11 (see FIG. 10).

  Thus, when it is determined that the water is submerged, the potential difference between the electrodes 170 and 200 is adjusted to a predetermined value or less. As a result, when the main body 12 is submerged, excessive current flow is prevented between the electrodes 170 and 200. Also in this example, the same function and effect as those of the first embodiment can be obtained. The electric resistance between the electrodes 170 and 200 can be set to any predetermined value (first predetermined value) and the predetermined value (second predetermined value) for the potential difference between the electrodes 170 and 200. It is. For example, in the case where the first predetermined value is set to a large value that can not be considered theoretically, and the second predetermined value is set to 0 V, similar to the first embodiment, when it is determined that water is submerged, the power feeding device 33 is Power supply to the electrodes 170 to 200 is stopped. As in the first embodiment, it is of course possible to turn off the switch 335 when the submersion state continues for a predetermined time (for example, one minute). Thereby, the early discharge of the battery 31 is prevented.

(Example 3)
The massage device 1 in the third embodiment includes a display unit 52 and a switching unit 8 as a bypass circuit 80, as shown in FIG. Further, the control unit 35 includes a switching control unit 354 instead of the power supply control unit 353 (see FIG. 9) of the first embodiment. The switching unit 8 connects a first current path 81 connecting the feeding unit 3 (feeding device 33) and the electrodes 170 to 200, and a bypass circuit 80 bypassing the feeding unit 3 (feeding device 33) and the electrodes 170 to 200. And the second current-carrying path 82 can be switched. The control mode for detecting a submerged state in the massager 1 of this example is performed 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 case of the first embodiment. And as shown in FIG.15 and FIG.16, after detecting the electrical resistance between a pair of submersion detection electrodes 60a and 60b in submersion sensor 60 in Step S11, between a pair of submersion detection electrodes 60a and 60b in Step S12. When it is determined that the electric resistance of the power supply is not less than or equal to the predetermined value (No in step S12), the control unit 35 determines whether the power feeding device 33 is connected to the electrodes 170 to 200 in the switching unit 8 (step S35). When it is determined that the connection is not made (No in step S35), the switching control unit 354 of the control unit 35 outputs the 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 conduction path 81 and connects the power feeding device 33 to the electrodes 170 to 200 (step S37). Thereafter, the power feeding device 33 is controlled to feed power to the electrodes 170 to 200 (step S38). On the other hand, when it is determined in step S35 that the power feeding device 33 is connected to the electrodes 170 to 200 (Yes in step S35), control is performed so that the power feeding device 33 feeds power to the electrodes 170 to 200 in step S38.

  On the other hand, if it is determined in step S12 that the electrical resistance between the pair of submersion detection electrodes 60a and 60b is less than or equal to the predetermined value (Yes in step S12), then in step S14, the massager 1 is in the submerged state. Then, the controller 35 outputs a submersion detection signal to the control unit 35 (step S39). Then, the control unit 35 determines in the switching unit 8 whether or not the power feeding device 33 is connected to the electrodes 170 to 200 (step S40). When it is judged that it is not connected (No of step S40), it returns to step S11 (refer FIG. 10). On the other hand, in step S40, when it is determined 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 the second switching signal to the switching unit 8. It outputs (step S41). When the second switching signal is input, the switching unit 8 switches from the first current path 81 to the second current path 82 to release the connection between the power feeding device 33 and the electrodes 170 to 200 and display the power feeding device 33. It connects to the part 52 (step S42). Then, the display unit 52 supplied with power from the power supply device 33 displays that the massager 1 is submerged (step S43).

  As a result, when it is determined that the apparatus is submerged, power supply to the electrodes 170 to 200 is stopped, and control is performed such that power is supplied to the display unit 52. As a result, when the main body 12 is submerged, excessive current flow is prevented between the electrodes 170 and 200. In addition, since it is displayed in the display unit 52 that the massager 1 is determined to be submerged, the user is controlled so that the current does not excessively flow between the electrodes 170 and 200. It can be easily recognized. Therefore, it is possible to pick up the massager 1 which has dropped into a bath tub and the like and which has been submerged. Also in this example, the same function and effect as those of the first embodiment can be obtained. Although the process is returned to step S11 (FIG. 10) after the process of step S43 is completed in FIG. 16, the process shown in FIG. 16 may be ended after the process of step S43 is completed. good. In that case, power feeding from the power feeding device 33 to the electrodes 170 to 200 is not resumed unless the user performs an instruction operation. Thereby, the resumption of the power supply to the electrodes 170-200 which the user did not intend can be suitably prevented. Further, it is of course possible to turn off the switch 335 when the submersion detection state continues for a predetermined time.

(Example 4)
As shown in FIG. 17, the massager 100 of the present example includes two rotating bodies 17 and 18 in place of the four rotating bodies 17 to 20 (see FIG. 1) in the first embodiment.

The rotating bodies 17 and 18 extend so as to radially spread on the lower surface side Y1 in the thickness direction Y of the main body 120.

  A solar cell panel 120d is installed on the upper surface side Y2 of the grip portion 120a. A rechargeable battery 31 (see FIG. 9) such as a nickel hydrogen battery is disposed inside the main body 120, and the power generated by the solar battery panel 120d is charged to the battery 31. Further, as shown in FIG. 18, a submersion sensor 60 as the submersion detecting unit 6 is provided on the lower surface side Y1 of the main body 120 and between the branch parts 120 b and 120 c. The configuration of the submersion sensor 60 is the same as that of the first embodiment, and the control mode in the submersion state is also the same as that of the first embodiment. The submersion sensor 60 may be disposed on the rotating members 17 and 18 or may be disposed on both the main body 120 and the rotating members 17 and 18.

  Also in the massage device 100 of this example, the same function and effect as those of the first embodiment can be obtained except for the effects of the provision of the four rotating bodies 17 to 20 in the first embodiment.

  In the massager 1 of the first embodiment, four electrodes 170 to 200 are provided, and in the massager 100 of the fourth embodiment, two electrodes 170 and 180 are provided. However, the present invention is not limited thereto. There may be five or more electrodes. Moreover, it is of course possible to make the control mode in the submerged state not the same as that of the first embodiment but the same as that of the second embodiment or the third embodiment.

  In each of the first to third embodiments, each of the electrodes 170 to 200 is formed on the rotators 17 to 20. However, the present invention is not limited to this. In at least two sheet-like pads, one surface of each of the electrodes is used as an electrode It may be adopted as In this case, the submersion detecting unit may be provided on the other surface of the pad. Thus, the submersion detecting unit can detect that the pad as the electrode is submerged. In addition, the electrode and the main body of the said pad shall be connected by the electric wire and signal wire | line | wire by which insulation coating was carried out. Also in this case, when the submersion detection unit detects submersion, control similar to any one of the first to third embodiments is performed.

In addition, it is possible for the rotary bodies 17-20 provided in the massager 1 mentioned above to separate and supply only this part as a rotary body apparatus for massaging machines. In this case, by using the massaging device rotating body device, it is possible to easily provide a massaging device excellent in the massaging effect.

(2) A plurality of annular belt-like surfaces are arranged in the axial direction of the inclined axis on the surface of the rotating body, and the cross-sectional outline can be seen as a boundary between the adjacent belt-like surfaces. The rotary device for a massage device according to (1), characterized in that

  According to the massaging device rotating body device described in the above (1), the rotating body can be smoothly rotated in a state where the body is in contact with the skin, and the feeling of use is excellent. In addition, when a plurality of massaging device rotating body devices are used in combination, it is possible to exert a skin picking effect and a soothing effect between the pair of massaging device rotating body devices, and it is possible to further improve the massaging effect. In (1), the term “spherical” and “elliptical sphere” are not limited to strict spheres and oval spheres, but generally includes substantially spherical shapes such as shapes in which spherical and oval spheres are recognized or shapes having some irregularities on the surface. It shall be

  In addition, when the above-mentioned massaging device rotating body device according to (1) is brought into contact with the skin and rotated, the cross-sectional contour line with respect to the axis is observed to change according to the rotation. Makes it easy to see that it is rotating.

  According to the massaging device rotating body device described in (2), since the cross-sectional outlines of the plurality of band-shaped surfaces as boundary lines are periodically changed and observed according to the rotation angle of the rotating body, the rotating body It is easy to see that it is rotating. Furthermore, since the plurality of band-shaped surfaces are arranged in the axial direction of the inclined axis, the direction of the band-shaped surface periodically changes according to the rotation of the rotating body, and therefore, a plurality of massaging device rotating body devices are used in combination In this case, strength is imparted to the skin's pick-up effect and the massage and rejuvenation effect between the pair of rotating bodies. As a result, while being able to improve a massage effect further, a user can be made to recognize effectively the pick-up effect of a skin, and the wrinkles and hoofing effect, and an excellent feeling of use can be obtained.

  The band-shaped surface formed in the annular shape has a shape different from that of the other band-shaped surface adjacent to the band-shaped surface so that the boundary line with the other band-shaped surface adjacent in the axial direction of the inclined axis is easily visible. preferable. For example, it is possible to make the shape of the strip surface and the other strip surfaces adjacent thereto in the cross section including the tilt axis straight, and to make the tilt angles of the both different from the tilt axis. Moreover, while making the shape of the said strip | belt-shaped surface in the cross section containing an inclination-axis line into linear form, the curved shape which expanded the shape of the other strip-shaped surface adjacent to this outside the rotary body or depressed inside the rotary body It can be done. Moreover, the shape of the said strip surface in the cross section containing an inclination-axis line and the other strip surface adjacent to this can be made into the curve shape hollowed inside the rotary body. In these cases, the boundary line (cross-sectional outline) of the band-shaped surface and the other band-shaped surface adjacent to the band-shaped surface can be clearly formed in a linear shape. For example, the strip surface and the cross-sectional contour can be formed as described above with reference to FIGS. 12 (a) -12 (d).

(Example 5)
As shown in FIG. 20, the massaging device 601 of this example is replaced with four electrodes 170 to 200 (see FIG. 2) formed on the surface of the conductive rotating bodies 17 to 20 in the first embodiment.

The case 611 includes a concave first case 651 and a second case 652 attached to the first case 651 and forming a storage portion 613 for storing the control board 641 between the first case 651 and the first case 651. Along the outer edge of the second case 652, a rib 652a provided upright is fitted inside the outer edge portion 651a of the first case 651, and the second case 652 is joined to the first case 651.

  As shown in FIGS. 19 and 22, the first case 651 is formed with a first cantilever 661a and a second cantilever 661b which form a part of an operation unit 660 described later. The first cantilever 661 a and the second cantilever 661 b are formed in a cantilever state by hollowing out a part of the wall of the first case 651. The first cantilever 661a and the second cantilever 661b are arranged in this order from the upper side to the lower side in the height direction H.

  Moreover, as shown to FIG. 19, FIG. 22, the massage device 601 is equipped with the submersion sensor 60 (60a, 60b) as the submergence detection part 6. FIG. The submersion sensor 60 is provided on the upper side in the height direction H of the main body portion 610 in the case 611. As shown in FIG. 22, the submersion sensor 60 a (60) is electrically connected to the control board 641 via the sensor harness 63. Then, as in the case of the first embodiment, control (see FIG. 10) for detecting a submerged state is performed. However, the massager 601 of this example includes a speaker 643 in place of the LED lamp 337 (see FIG. 9) in the first embodiment. Then, when the submersion is detected, instead of the lighting notification of the LED lamp 337 in the first embodiment, a sound (for example, an electronic sound such as "pi, pi, pi") is output and notified. There is.

The switch mechanism 662 is electrically connected to the control board 641. The switch mechanism 662 is disposed immediately below the first cantilever 661 a and the second cantilever 661 b formed in the first case 651. As a result, when the first cantilever 661a is pressed from the outside through the operation surface 664 of the outer shell former 612 covering the first case 651, the first cantilever 661a in the cantilevered state is bent, whereby the switch mechanism 662 is The switch unit 663 is pressed. Then, when the pressing on the operation surface 664 is released, the first cantilever 661a returns to the original position by the restoring force of the first cantilever 661a in the cantilever state. The second cantilever 661b is also configured to perform pressing and releasing in the same manner.

  As shown in FIG. 22, the second case 652 is provided with a power supply unit 620 including power supplied to the power supply unit 3 (see FIG. 9). In the second case 652, a battery holding portion 614 for holding the battery 31 constituting the power supply portion 620 is formed. The battery holding portion 614 is detachably attached with a lid 615 for preventing the battery 31 from falling off. The lid 615 has a disk shape that is a size larger than the battery 31, and an O-ring 616 for sealing between the lid 615 and the second case 652 is fitted around the lid. The battery 31 is electrically connected to the control board 641 via a lead (not shown). As shown in FIG. 20, in the second case 652, a plurality of linear grooves 653 extending radially from the outer periphery of the lid 615 are formed at equal intervals.

  As shown in FIG. 20, a first electrode group 670 and a second electrode group 680 are provided as electrode parts. As shown in FIGS. 20 and 23, the first electrode group 670 extends from the main body 610 so as to be positioned on the right side W1 of the person 602 relative to the center line 610a when attached to the abdomen 603. The second electrode group 680 extends from the main body 610 so as to be positioned on the left side W2 of the person 602 relative to the center line 610a when attached to the abdomen 603. As shown in FIG. 20, the first electrode group 670 includes the right electrodes 671 to 673, and the second electrode group 680 includes the left electrodes 681 to 683.

  Each of the electrodes 671 to 673 and 681 to 683 is formed in a substantially rectangular shape with rounded corners. The longitudinal direction of each of the electrodes 671 to 673 and 681 to 683 (for example, the direction indicated by symbol d in the third right electrode 673) is substantially along the lateral direction W. In this example, each of the electrodes 671 to 673 and 681 to 683 has the same shape. The shape of each of the electrodes 671 to 673 and 681 to 683 is, for example, h / d is 0.40 to 0.95, preferably 0, where the length in the longitudinal direction is d and the length in the lateral direction is h. In this example, h / d is 0.55.

  As shown in FIG. 22, the second case 652 is formed with a collar portion 652 b protruding to the outside of the rib 652 a. A sheet-like base 633 is held between the flange portion 652 b and the outer edge portion 651 a of the first case 651 via a waterproof double-sided seal (not shown). The substrate 633 is made of PET and has flexibility. As shown in FIG. 20, the base material 633 spreads over the entire surface (back surface 633 a) opposite to the surface (front surface) on the outer shell forming body 612 side of the massager 601. Then, as shown in FIGS. 19 and 21, the front side surface of the base 633 is covered by an outer shell forming body 612 extended from the main body portion 610. The base 633 and the shell former 612 are bonded by a 3M adhesive tape and a silicon adhesive treatment (not shown).

  As shown in FIG. 20, a plurality of electrode non-formed portions 634 having a predetermined size and a hexagonal shape are formed inside the respective electrodes 671 to 673 and 681 to 683 at predetermined intervals. Further, lead portions 674, 675, 676 for connection to the control substrate 641 are formed on the respective right side electrodes 671, 672, 673 so as to be drawn out from the main body portion 610. Similarly, lead portions 684, 685, 686 for connecting to the control substrate 641 are formed on the left side electrodes 681, 682, 683, respectively, so as to be drawn out from the main body portion 610. Each lead portion 674 to 676 and 684 to 686 is coated with a silicon so that it can not be conducted to the outside. In addition, in each of the electrodes 671 to 673 and 681 to 683, a silicon coating is applied also to a portion connected to the lead portions 674 to 676 and 684 to 686 and a region in the vicinity thereof (hatched region indicated by symbol C in FIG. 20). , Can not be connected to the outside. The right electrodes 671 to 673 are connected in parallel to one another, and the left electrodes 681 to 683 are also connected in parallel to one another.

  As shown in FIG. 20, the electrode portion (the first electrode group 670, the second electrode group 680) is formed on the back surface 633a of the base 633. Thus, the electrode units (first electrode group 670, second electrode group 680) are integrally formed with the main body 610. And since it is formed in the base material 633 which has flexibility, an electrode part (the 1st electrode group 670, the 2nd electrode group 680) also has flexibility. The first electrode group 670 and the second electrode group 680 are formed by printing a conductive ink containing silver paste on the back surface 633 a of the substrate 633. The first electrode group 670 and the second electrode group 680 collectively include four or more electrodes 671 to 673 and 681 to 683.
