Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the scalp care device 1 according to the present embodiment includes a main body housing 11 having a substantially rectangular parallelepiped appearance, and a drive source that is housed and held in the main body housing 11 and rotationally drives the output shaft 12. As a motor 13. The scalp care device 1 includes a treatment element 15 having a projection 14 that is connected to the tip of the output shaft 12 protruding from the main body housing 11 and is driven based on the rotation of the output shaft 12. Moreover, the scalp care device 1 of the present embodiment includes an electrical stimulation generating means (circuit) 16 for applying electrical stimulation from the protrusion 14 to the scalp.

On the side of the main body housing 11, a switch 17 is provided for the user to turn on and off the scalp care device 1.
The output shaft 12 is rotatably supported by the main body housing 11 via a bearing 18 so that the tip side protrudes from the upper portion of the main body housing 11 to the outside. An output shaft gear 12 a is provided on the output shaft 12 on the proximal end side in the main body housing 11.

  The motor 13 is capable of rotating the rotary shaft 13a, and a rotary shaft gear 13b is provided at the tip of the rotary shaft 13a. The motor 13 can be driven to rotate the output shaft 12 by being housed and held in the main body housing 11 so that the rotary shaft gear 13b is engaged with the output shaft gear 12a. The motor 13 is electrically connected to a control unit 19 accommodated and held in the main body housing 11, and the control unit 19 is electrically connected to a power source unit (battery) 20 accommodated and held in the main body housing 11. The power supply unit 20 is electrically connected to the switch 17.

  The treatment element 15 includes a rotating member 21 provided so as to be rotatable with respect to the output shaft 12 about the second axis X2 that is shifted from the first axis X1 that is the center of the output shaft 12, and the second axis X2. And a plurality of protrusions 14 provided on the rotating member 21 so as to be disposed around. In the present embodiment, four protrusions 14 (only two are shown in FIG. 1) are provided on the treatment element 15.

  Specifically, the distal end of the output shaft 12 and the treatment element 15 are connected via a rotating plate 22, a rotation support member 23, and a bearing 24. The rotating plate 22 is formed in a disk shape, and the tip of the output shaft 12 is fitted and fixed in the center hole 22a. The rotation support member 23 is formed in a substantially columnar shape, and a flange portion 23a is formed at the lower end. The center of the rotation support member 23 is the center of the second axis X2 that is shifted from the first axis X1 that is the center of the output shaft 12. In this way, it is fixed on the rotating plate 22. The rotation support member 23 has a position of the second axis X2 that is the axis center of itself (the rotation support member 23) from the position of the first axis X1 that is a position corresponding to the output shaft 12 on the lower surface. A communication hole 23b is formed in the upper surface. On the other hand, the rotating member 21 of the surgical element 15 includes a substantially disc-shaped disc portion 21a and a cylindrical portion 21b extending in a cylindrical shape from the lower surface of the disc portion 21a. The surgical element 15 is rotatably supported by the outer peripheral surface of the rotation support member 23 through the bearing 24 on the inner peripheral surface of the cylindrical portion 21 b of the rotating member 21. The rotating member 21 is formed with a communication hole 21c that is vertically centered at the position of the second axis X2 and is the axis center of itself (the rotating member 21). The protrusions 14 are made of conductive rubber (for example, NBR (nitrile rubber) or a copolymer of butadiene and acrylonitrile), and the four protrusions 14 are erected and integrally formed on one base portion 14a. A base plate 14b, which is a conductive metal plate, is embedded in the base portion 14a. The protrusions 14 of the present embodiment are formed in a substantially conical shape, and are arranged at equal distances (90 °) at equal distances around the second axis X2.

  The electrical stimulation generating means 16 accommodated and held in the main body housing 11 is connected to the proximal end portion of the conducting wire 31, and the conducting wire 31 is connected to the output shaft 12 (the hole at the center of the shaft) and the communication holes 23b and 21c. The tip is connected to and electrically connected to the base plate 14b. The electrical stimulation generating means 16 is connected to the proximal end portion of the conducting wire 32, and the leading end portion of the conducting wire 32 is connected to and electrically connected to the gripping electrode portion 33 provided on the gripping portion 11 a of the main body housing 11. ing. Thereby, in this Embodiment, the processus | protrusion 14 is made into the positive electrode and the holding electrode part 33 is made into the negative electrode.

  The main body housing 11 is provided with a cover 41 that covers the periphery of the output shaft 12 protruding from the main body housing 11. Specifically, the cover 41 is made of a resin material, and a fixing portion 41a fixed to the main body housing 11 (specifically, the entire outer surface thereof), and an exposed periphery (radially outer side) of the output shaft 12 from the fixing portion 41a. And a cover main body 41b extending in a substantially cylindrical shape so as to cover. The upper end of the cover body 41b has a first opening 41c that has a slightly larger opening 41c than the moving locus range of the rotating member 21, in other words, a circular opening 41c centered on the first axis X1. A lid portion 41d extending in the direction orthogonal to the axis X1 is formed. Further, the cover 41 of the present embodiment allows the rotation (circulation) of the surgical element 15 about the first axis X1 and follows the rotation of the surgical element 15 about the first axis X1. It has a deformable bellows member 42 that partitions the outside and the output shaft 12 side. The bellows member 42 is made of an elastic body (insulating rubber or the like) and is formed in a bellows shape, and one end opening portion (outer edge) thereof is fixed to the opening 41c. Further, the bellows member 42 is viewed from the direction of the first axis X1 as each projection 14 passes through a hole 42a (see FIG. 2) formed in the bellows member 42 and engages with the bellows member 42. Thus, the state in which the positional relationship of the protrusion 14 with respect to the second axis X2 does not change is maintained. That is, in this example, the bellows member 42 made of an elastic body allows the movement (rotation) of the surgical element 15 about the first axis X1, but resists the rotation of the surgical element 15 that twists itself. Thus, the positional relationship of the protrusion 14 with respect to the second axis X2 is prevented from changing. Thereby, it is prevented that the conducting wire 31 connected to the base plate 14b is twisted and disconnected.

  In the scalp care device 1 configured as described above, when the switch 17 is turned on by the user, power is supplied from the power supply unit 20 to the control unit 19 and the control unit 19 rotates the rotating shaft 13 a to the motor 13. A drive current for driving is supplied.

  When the rotating shaft 13a of the motor 13 is driven to rotate, the output shaft 12 and the rotating plate 22 rotate integrally around the first axis X1. At this time, the rotation support member 23 and the treatment element 15 (the axis center thereof) rotate about the first axis X1 so as to go around the first axis X1. At this time, each protrusion 14 passes through a hole 42a formed in the bellows member 42 and engages with the bellows member 42, so that the protrusion 14 with respect to the second axis X2 as viewed from the first axis X1 direction. The surgical element 15 rotates (circulates) around the first axis X1 while maintaining the positional relationship. When the distal end (projection 14) of the surgical element 15 is brought into contact with the scalp, the user's scalp is moved in accordance with the movement of the distal end of the projection 14, and the scalp is cared for (washed or massaged). Become.

At this time, the control unit 19 supplies power to the electrical stimulation generating means 16, and electrical stimulation is applied to the scalp from the protrusion 14 (positive electrode).
Next, characteristic effects of the above embodiment will be described below.

  (1) Since the electrical stimulation generating means 16 for applying electrical stimulation to the scalp from the protrusion 14 is provided, for example, when the protrusion 14 is a positive electrode as in the present embodiment, dirt clogged in pores ( Sebum and waste products) can be adsorbed, and the cleaning effect can be enhanced.

  (2) Since the protrusion 14 is a positive electrode and the gripping electrode portion 33 that is a negative electrode is provided on the gripping portion 11a of the main body housing 11, the cleaning effect can be enhanced. That is, in the case where only the positive electrode (projection 14) is in contact with the human body, the human body is charged only positive and current does not flow easily, but this can be avoided and the cleaning effect can be enhanced. In addition, the natural usage method of grasping the grasping portion 11a makes it easy for current to flow through the human body through the scalp and the hand, thereby enhancing the cleaning effect.

The above embodiment may be modified as follows.
In the above embodiment, the protrusion 14 is a positive electrode and the grip electrode part 33 is a negative electrode. However, the present invention is not limited to this, and the protrusion 14 is a negative electrode and the grip electrode part 33 is a positive electrode. Also good. Thus, when the protrusion 14 is a negative electrode, the effect (agent penetration effect) of penetrating an agent (for example, a hair growth agent) can be enhanced. Further, without the gripping electrode portion 33, only one of the positive electrode and the negative electrode (projection 14) may be changed to be in contact with the human body.

  In the above embodiment, the protrusion 14 is a positive electrode and the grip electrode part 33 is a negative electrode. However, the present invention is not limited to this, and at least one of the plurality of protrusions is a positive electrode. In addition, the other at least one protrusion may be changed to a negative electrode.

  For example, you may change as shown in FIG.3 and FIG.4. As shown in FIG. 3, the protrusions 51a and 51b in this example are each made of conductive rubber, and the base ends thereof are connected by an insulating base 51c. A base plate 51d, which is a conductive metal plate, is embedded in the base end portions of the protrusions 51a and 51b.

  Further, in the rotating member 21, the communication hole 21c in the above embodiment is changed to a branch communication hole 21d. The branch communication hole 21d is formed so as to branch off from the position of the second axis X2 to the upper surface of the position where the protrusions 51a and 51b are fixed. ing. The electrical stimulation generating means 16 is connected to the base end portions of the conducting wires 31 and 32, and the conducting wires 31 and 32 are connected to the output shaft 12 (the shaft center hole), the communication hole 23b, and the branch communication hole 21d. The tip is connected to and electrically connected to each base plate 51d. Thus, the protrusion 51a connected to the conductor 31 is a positive electrode, and the protrusion 51b connected to the conductor 32 is a negative electrode. In the present embodiment, as shown in FIG. 4, four protrusions 51a and 51b are provided, two protrusions 51a are positive electrodes, and the other two protrusions 51b are negative electrodes. Yes. Further, in this example (see FIGS. 3 and 4), the grip electrode portion 33 of the above embodiment is omitted.

  In this case, at least one protrusion (51a) is a positive electrode and the other at least one protrusion (51b) is a negative electrode, so that the cleaning effect and the agent penetration effect are enhanced. be able to. That is, in the case where only one of the positive electrode and the negative electrode is in contact with the human body, the human body is charged only in either the positive or the negative and it becomes difficult for the current to flow. The effect and the agent penetration effect can be increased. Regardless of how the holding part 11a is held, the current can easily flow through the human body simply by bringing the plurality of protrusions 51a and 51b into contact with the scalp, and the cleaning effect and the agent penetration effect can be enhanced.

  Further, for example, as shown in FIG. 5, in the case of three protrusions 51a and 51b, two protrusions 51a may be positive electrodes and the other one protrusion 51b may be a negative electrode. Thus, if the number of protrusions 51a that are positive electrodes is larger than the number of protrusions 51b that are negative electrodes, the cleaning effect can be improved compared to the opposite case (when the number of protrusions 51b that are negative electrodes is increased). Can be higher.

  Further, for example, it may be changed as shown in FIGS. In this example, two or more surgical elements 15 and 62 having a plurality of projections 14 and 61 (four in this example) are provided so as to perform different operations (two in this example). A plurality of protrusions 14 in at least one (one in this example) treatment element 15 are used as positive electrodes, and a plurality of protrusions in at least one other (one in this example) treatment element 62. 61 is a negative electrode.

  Specifically, in the scalp care device 1 of this example, a pair of the output shaft 12, the motor 13, the treatment elements 15 and 62, and the like are arranged side by side. The conductor 31 is connected to the base plate 14b in one of the surgical elements 15 so that the four protrusions 14 are all positive electrodes, and the conductor 32 is connected to the base plate 61a of the other surgical element 62. Are connected so that the plurality of protrusions 61 are all negative electrodes.

  In this case, since two or more surgical elements 15 and 62 having a plurality of protrusions 14 and 61 are provided to perform different operations, physical stimulation is performed by different operations (for example, over a wide range of the scalp). Can be granted. Further, since the positive electrode or the negative electrode is different for each of the surgical elements 15 and 62, the surgical elements 15 and 62 are compared with the case where the positive electrode and the negative electrode are provided in one surgical element (see FIG. 3). The structure itself is simple.

  Further, for example, as shown in FIG. 8, in the case where three treatment elements 15 and 62 having a plurality of protrusions 14 and 61 are provided so as to perform different operations, a plurality of protrusions 14 in two treatment elements 15 are provided. A positive electrode may be used, and a plurality of protrusions 61 in one treatment element 62 may be negative electrodes. As described above, when the number of the protrusions 14 that are positive electrodes is larger than the number of the protrusions 61 that are negative electrodes, the cleaning effect can be improved compared to the opposite case (when the number of protrusions 61 that are negative electrodes is increased). Can be higher.

  -You may abolish the holding electrode part 33 of the said embodiment, and may change as shown in FIG. That is, the scalp care device 1 of this example (see FIG. 9) is provided with a cylindrical guide portion 71 that can be expanded and contracted so that the projection 14 is in contact with the scalp around the projection 14 while the projection 14 is in contact with the scalp. The cylindrical guide portion 71 is a negative electrode. Specifically, the cover 41 of this example (see FIG. 9) is provided with a cylindrical guide portion 71 extending along the protruding direction of the protrusion 14 so as to surround the protrusion 14. The cylindrical guide portion 71 is made of conductive rubber and has a bellows shape that can be expanded and contracted along the protruding direction of the protrusion 14. The lead wire 32 is electrically connected to the cylindrical guide portion 71.

  Even if it does in this way, a cleaning effect and an agent penetration effect can be made high. That is, if only one of the positive electrode and the negative electrode is in contact with the human body, the human body is charged only to either positive or negative, making it difficult for current to flow. And the agent penetration effect can be increased. Regardless of how the grasping part 11a is held, the cylindrical guide part 71, which is a negative electrode, also comes into contact with the scalp simply by bringing the projection 14 made a positive electrode into contact with the scalp. Can easily flow, and the cleaning effect and the agent penetration effect can be enhanced.

  -You may change the said embodiment as shown in FIG.10 and FIG.11. In this example, two or more (two in this example) surgical treatment elements 15 having protrusions 14 (four in this example) are provided so as to repeat the operation of periodically approaching and separating. And the control part 19 controls the said electrical stimulus generation | occurrence | production means 16 so that an electrical stimulus may be provided between the timing from which the distance between the treatment elements 15 became the narrowest to the timing which became the widest.

  Specifically, in the scalp care device 1 of this example, a pair of the output shaft 12 and the treatment element 15 and the like are arranged side by side, and the output shaft 12 added to the above embodiment (the right output in FIG. 10). The shaft 12) is drivingly connected to the rotary shaft gear 13b via a reversing gear 81. As shown in FIG. 11, these two surgical elements 15 are set so as to perform a line-symmetric operation around a straight line L1 passing between them as viewed from the first axis X1 direction. As a result, when the switch 17 is turned on (timing T1 in FIG. 12), the two surgical elements 15 (protrusions 14) repeat the operation of periodically approaching and moving away from each other (the “distance between surgical elements in FIG. 12). )), And it works to pinch the scalp. Then, as shown in FIG. 12, the control unit 19 sets the electrical stimulation generating means 16 so as to apply the electrical stimulation between the timing T2 when the distance between the surgical elements 15 is the narrowest and the timing T3 when the distance is the widest. (On / off) control. Note that the control unit 19 generates electrical stimulation based on information detected by a sensor (not shown) (for example, a rotary encoder capable of detecting the rotation angle of the rotary shaft 13a) (and thus the distance between surgical elements shown in FIG. 12). The means 16 is controlled.

  In this way, it is possible to effectively remove dirt (sebum and waste) clogged in pores while suppressing wasteful power. That is, when the distance between the surgical elements 15 is narrowed, the efficiency is bad because the force is applied in the direction in which the pores are contracted even if electrical stimulation is applied, but the distance between the surgical elements 15 increases. Since the electrical stimulation is applied, the dirt clogged in the pores can be efficiently removed.

  In the above embodiment, the scalp care device 1 in which the protrusion 14 (the treatment element 15) is rotationally driven is used, but the protrusion is driven by the driving force of the driving source, and the protrusion is brought into contact with the scalp to care for the scalp. If it does, you may provide and implement | achieve the electrical stimulus generation | occurrence | production means 16 in another scalp care apparatus. For example, the scalp care device simply configured to vibrate the protrusion may be provided with the electrical stimulation generating means 16 for applying electrical stimulation to the scalp from the protrusion.
