The rotation axis L is set at the center of the inner housing 3 and the center of the outer housing 2 in plan view (see FIG. 2).

  Inside the inner housing 3, a battery 11 as a power source and a motor 14 as a drive source for rotationally driving the two output shafts 12 and 13 are housed and held. The motor 14 is driven based on the electric power of the battery 11. The output shafts 12 and 13 are rotatably supported by bearings 19a and 19b provided on the upper wall portion 3c of the inner housing 3 so that the tip side protrudes from the upper portion of the inner housing 3 to the outside. Output shaft gears 12 a and 13 a are provided on the proximal end side of the output shafts 12 and 13 in the inner housing 3. In addition, a switch 18 is provided on the side wall 3b of the inner housing 3 so that the user can turn on and off the scalp care device 1.

  The motor 14 is capable of rotationally driving the rotary shaft 14a, and a rotary shaft gear 14b is provided at the tip of the rotary shaft 14a. The motor 14 is housed and held in the inner housing 3 so that the rotary shaft gear 14b is engaged with the output shaft gear 12a, so that the output shaft 12 can be driven to rotate. The motor 14 is supported so that the rotating shaft gear 14b is rotatably supported in the inner housing 3 and is engaged with the reversing gear 20 that is engaged with the output shaft gear 13a. Can be driven to rotate in the opposite direction to the output shaft 12. The motor 14 is electrically connected to a control unit 21 housed and held in the inner housing 3, and the control unit 21 is electrically connected to the battery 11 and the switch 18.

  At the tips of the output shafts 12 and 13, surgical elements 16 and 17 each having a projection 15 are connected. The surgical elements 16 and 17 include a rotating member 31 provided so as to be rotatable with respect to the output shafts 12 and 13 about the second axis X2 that is shifted from the first axis X1 that is the center of the output shafts 12 and 13. It has a plurality of protrusions 15 provided on the rotating member 31 so as to be arranged at a position deviated from the first axis X1 (arranged around the second axis X2). In the present embodiment, four protrusions 15 are provided for each of the treatment elements 16 and 17 (only two are shown in FIG. 1).

  Specifically, the distal ends of the output shafts 12 and 13 and the treatment elements 16 and 17 are connected via a rotating plate 32, a rotation support member 33, and a bearing 34. The rotary plate 32 is formed in a disc shape, and the tips of the output shafts 12 and 13 are fitted and fixed in the center hole 32a. The rotation support member 33 is formed in a substantially cylindrical shape and has a flange portion at the lower end, and the center of the shaft is offset from the first axis X1 that is the center of the output shafts 12 and 13, and the center of the second axis X2 It is being fixed on the said rotating plate 32 so that it may become. On the other hand, the rotating member 31 of the treatment elements 16 and 17 includes a substantially disk-shaped disk part 31a and a cylinder part 31b extending in a cylindrical shape from the lower surface of the disk part 31a. The surgical elements 16, 17 are rotatably supported on the outer peripheral surface of the rotation support member 33 through the bearings 34 on the inner peripheral surface of the cylindrical portion 31 b of the rotary member 31.

  The protrusions 15 are made of an elastic member such as an elastomer and are formed in a substantially conical shape. In this embodiment, four protrusions 15 are fixed so as to protrude upward (in parallel to the second axis X2) on the disk portion 31a. Has been. The four protrusions 15 in each of the surgical elements 16 and 17 are arranged at equal distances (90 °) at equal distances around the second axis X2. The surgical elements 16 and 17 are rotationally driven in opposite directions by the output shafts 12 and 13 connected thereto, respectively. The surgical elements 16 and 17 in this embodiment are lined with respect to a perpendicular bisector Y of a line segment connecting the output shafts 12 and 13 when viewed from the axial direction of the output shafts 12 and 13 to be connected. It is set to work symmetrically.

  In the scalp care device 1 configured as described above, when the switch 18 is turned on by the user, the control unit 21 generates a driving current for rotating the motor 14 (its rotating shaft 14a) from the battery 11 to the motor. 14. When the rotating shaft 14a of the motor 14 is rotationally driven, the output shafts 12, 13 and the rotating plate 32 rotate integrally around the first axis X1. At this time, the rotation support member 33 and the treatment elements 16 and 17 (centers thereof) rotate around the first axis X1 so as to go around the first axis X1. When the projections 15 of the treatment elements 16 and 17 are brought into contact with the scalp, the user's scalp is moved in accordance with the movement of the projection 15 so that the scalp is massaged.

  Since the surgical elements 16 and 17 are rotatably supported around the second axis X2, for example, a protrusion with respect to the second axis X2 due to a load such as friction with the scalp or hair that is in contact with the protrusion 15 It is possible to rotate around the first axis X1 while keeping the positional relationship of 15 constant. Therefore, depending on the load (friction with the scalp and hair, etc.), the hair is entangled with the surgical element based on the movement in which each protrusion 15 simply rotates about the first axis X1 (each with a respective radius). It is possible to avoid such a phenomenon. Further, when the two surgical elements 16 and 17 of the present embodiment rotate around the first axis X1 and operate so as to approach each other, the respective projections 15 (groups) thereof It is possible to give stimulation by sandwiching the scalp between them.

  In the scalp care device 1 as described above, the weight W is fixed to the inner side surface of the side wall portion 3 b of the inner housing 3. The weight W has a rectangular flat plate shape when viewed from the side, and the center (center of gravity) thereof is provided at a position where it overlaps the vertical bisector Y connecting the output shafts 12 and 13 in plan view. Here, as shown in FIG. 2, the center of gravity of the inner housing 3 excluding the weight W is the center between the treatment elements 16 and 17 (in this embodiment, the center C between the output shafts 12 and 13, It is set so as to overlap the center of the line segment connecting the first axes X1). As a result, the center of gravity G of the inner housing 3 including the weight W is set at a position on the vertical bisector in plan view and shifted from the center C between the output shafts 12 and 13.

  The center C between the output shafts 12 and 13 is set so as to be positioned on the rotation axis L of the inner housing 3 with respect to the outer housing 2 (center of the shaft portion 5). That is, the center of gravity G of the inner housing 3 is set on a vertical bisector Y of a line segment connecting the output shafts 12 and 13 in a plan view and shifted from the rotation axis L of the inner housing 3.

  As described above, since the center of gravity G of the inner housing 3 is deviated from the rotation axis L, the inner housing 3 is in the state where the rotation axis L is inclined with respect to the vertical direction (including the state where the rotation axis L is horizontal). The center of gravity G (weight W) rotates so as to be directly below the rotation axis L. When the center of gravity G of the inner housing 3 is located directly below the rotation axis L, the tips of the output shafts 12 and 13 (that is, the treatment elements 16 and 17) are horizontally aligned, and the treatment elements 16 and 16 A massage that pinches the scalp between 17 is performed. In the scalp care device 1 of the present embodiment, the direction of the inner housing 3 in which the treatment elements 16 and 17 are arranged horizontally is the direction of the inner housing 3 that can effectively perform scalp massage.

  In such a scalp care apparatus 1, the user performs scalp massage by holding the outer housing 2 and bringing the surgical elements 16 and 17 into contact with the scalp. At this time, the direction of the inner housing 3 is kept constant so that the treatment elements 16 and 17 are aligned horizontally regardless of the direction of the outer housing 2. For example, even when the outer housing 2 is rotated 90 ° around the rotation axis L from the state shown in FIG. 2, the orientation (rotation angle) of the inner housing 3 is such that the center of gravity G is positioned below the rotation axis L, that is, The surgical elements 16 and 17 are kept in a horizontal state so that they can be sandwiched and massaged. For this reason, it is not necessary for the user to consciously adjust the direction of the scalp care device 1 to a suitable direction (the surgical elements 16, 17 are horizontal) during scalp massage, and an effective scalp massage is easily performed. It is possible.

  Further, in the scalp care device 1 of the present embodiment, since the center of gravity G of the inner housing 3 is displaced from the rotation axis L by the weight W provided in the inner housing 3, the inner housing can be obtained only by adding the weight W. Automatic adjustment of the direction of 3 is possible. In addition, since the center C between the output shafts 12 and 13 is configured to be positioned on the rotation axis L of the inner housing 3, rotation blur of the inner housing 3 during use is suppressed. .

Next, characteristic effects of the present embodiment will be described.
(1) The inner housing 3 provided with the surgical elements 16 and 17 is rotatably supported with respect to the outer housing 2, and can be automatically adjusted so that the orientation of the inner housing 3 is kept constant regardless of the orientation of the outer housing 2. Configured. Thus, when the scalp is massaged with the surgical elements 16 and 17 provided on the inner housing 3 while holding the outer housing 2, the orientation of the inner housing 3 is automatically fixed regardless of the orientation of the outer housing 2. Kept. For this reason, if the direction of the inner housing 3 is set so that the surgical elements 16 and 17 are effectively in contact with the scalp, the user consciously sets the direction of the scalp care device 1 to a suitable direction during the scalp massage. There is no need to match. Therefore, effective scalp massage can be easily performed.

  (2) The center of gravity G of the inner housing 3 is deviated from the rotation axis L, and the direction of the inner housing 3 can be automatically adjusted while the rotation axis L of the inner housing 3 is inclined with respect to the vertical direction. Is done. In general, the scalp care device 1 is in a state in which the rotation axis L of the inner housing 3 is inclined with respect to the vertical direction in the state of use. In this state, the center of gravity G of the inner housing 3 has the rotation axis L of the inner housing 3. Rotate so that it is directly underneath. Thereby, the direction of the inner housing 3 is automatically adjusted. Therefore, the inner housing 3 can be automatically adjusted so as to be kept constant regardless of the direction of the outer housing 2 with a simple configuration.

  (3) The inner housing 3 is provided with a weight W for shifting the center of gravity G of the inner housing 3 from the rotation axis L of the inner housing 3. For this reason, the center of gravity G of the inner housing 3 can be shifted from the rotation axis L of the inner housing 3 only by adding the weight W. In addition, since the direction of displacement of the center of gravity G of the inner housing 3 with respect to the rotation axis L can be set by the position where the weight W is provided, the direction of the inner housing 3 can be set with a simple configuration.

  (4) Since the center C between the two treatment elements 16 and 17 (output shafts 12 and 13) is positioned on the rotation axis L of the inner housing 3, the rotation of the inner housing 3 during use is performed. Blur can be suppressed. This action and effect is particularly noticeable when the treatment elements 16 and 17 are configured to rotate in synchronization with the first axis X1.

It consists of an inner surface 3e.

  In the example shown in FIG. 5, after the weight W is inserted into the hook 41 in the first axis X1 direction (the direction orthogonal to the paper surface), the weight W is removed from the hook 41 by attaching a lid (not shown). There is no such thing. Alternatively, the hook 41 may have a snap-fit structure, and the weight W may be detachably attached by inserting it into the hook 41 from a direction (paper surface direction) perpendicular to the first axis X1.

  As shown in FIG. 5 (a), when the weight W is attached to the hook 41 on the inner side surface 3d, the orientation of the inner housing 3 is constant so that the surgical elements 16, 17 are aligned horizontally regardless of the orientation of the outer housing 2. To be kept. On the other hand, as shown in FIG. 5B, when the weight W is attached to the hook 41 of the inner side surface 3e, the surgical elements 16, 17 are arranged vertically regardless of the direction of the inner housing 3 regardless of the direction of the outer housing 2. To be kept constant. According to such a configuration, it is possible to keep the inner housing 3 constant in the direction according to the user's preference depending on the installation position of the weight W.
