Rotate to be line-symmetric with each other.

  According to such a configuration, the centers P1 and P3 of the surgical elements 81a and 81c and the centers P2 and P4 of the surgical elements 81b and 81d are most distant from each other in the front-rear direction (by rotating 90 degrees in the reverse direction from FIG. 9). 9), when each of the surgical elements 81a to 81d is rotated by 90 degrees, as shown in FIG. 9, the surgical elements 81a and 81c are brought closest to each other in the left-right direction, and the surgical elements 81a and 81c are treated. It operates to pinch and squeeze between the protrusions 83. At this time, the scalp sandwiched between the surgical elements 81a and 81c is moved in the rotation direction.

  Further, when the surgical elements 81a to 81d rotate 90 degrees, in the surgical elements 81a and 81b rotating in the same direction, the centers P1 and P2 of the surgical element base portions 82 are closest to each other at the same timing. Then, when the space between the surgical elements 81a and 81b is viewed locally, the surgical elements 81a and 81b rotate around each other so as to pass each other. As a result, the scalp is sandwiched between the surgical elements 81a and 81b that approach at the same timing, and a twisting motion can be imparted to the scalp by passing each other. When the surgical elements 81a and 81b that perform the pinching and twisting movements are brought into contact with the scalp, the user's scalp is effectively moved in accordance with the movement of the surgical elements 81a and 81b. As a result, the scalp is cared for (massaged). In addition, in the surgical elements 81c and 81d, the same pinching and twisting movement as in the surgical elements 81a and 81b is performed.

  Further, when each of the surgical elements 81a to 81d is rotated 90 degrees (rotated 180 degrees from the state shown in FIG. 9), the surgical elements 81b and 81d operate so as to sandwich and squeeze them. At this time, the surgical elements 81b and 81d are in a state of being closest to each other in the left-right direction, and operate so as to perform pinching between the surgical protrusions 83 of the surgical elements 81a and 81c. At this time, as described above, the scalp sandwiched between the surgical elements 81a and 81c is moved to the surgical elements 81b and 81d by the operation of the surgical elements 81a and 81c, and is continuous with the surgical elements 81b and 81d. The operation of moving the user's scalp in the same direction is performed.

  In this way, in the example as shown in FIG. 9, different types of movement can be given to the scalp according to the rotation angle of each of the surgical elements 81a to 81d (centers P1 to P4). It can contribute to the improvement of care effect.

  In the scalp care device 10 configured as described above, when the treatment head portion 12 is viewed in the axial direction, the shape of the treatment head portion 12 is a polygonal shape (approximately) having a plurality of (four) curved corners K. Square). And the center of the connection shaft 47 which is the approximate center of the operation area | region of each treatment element 81a-81d is located on the line which connects each corner | angular part K and the center of the treatment head part 12. FIG. More specifically, the center of the connecting shaft 47 is set to a position that is substantially the center on a line segment that connects each corner K and the center of the treatment head 12. For this reason, the treatment elements 81a to 81d can be set to a substantially equivalent area between the treatment elements 81a to 81d, while the treatment areas of the treatment elements 81a to 81d operated in the direction orthogonal to the axis (a direction perpendicular to the vertical direction) can be set. It becomes possible to expand the treatment area of the maximum. Further, when compared with the case where the diameter from the center of the treatment head portion 12 is set to the length to the corner K when the treatment head portion 12 is viewed in the axial direction as a circular shape, By doing so, the area of the treatment head portion 12 in the direction perpendicular to the axis can be suppressed. As a result, the scalp care device 10 can be reduced in size.

  The surgical elements 81a to 81d are connected at the positions where the centers P1 to P4 (corresponding to the center of the final output shaft 56) of the surgical protrusions 83 provided on the surgical elements 81a to 81d are shifted from the axial center of the connecting shaft 47. It is circulated around the axis center of the shaft 47. Here, for example, compared with the case where the axial center of the connecting shaft 47 and the centers P1 to P4 (the center of the final output shaft 56) of the treatment projection 83 are coaxial, it is possible to give a stimulus to a wider range. become.

Next, characteristic effects of the present embodiment will be described.
(1) The treatment head portion 12 has a polygonal shape having a plurality of corner portions K when viewed from the axial direction of the final output shaft 56 and the connecting shaft 47, and the treatment elements 81a to 81d are located at positions corresponding to the corner portions K. Provided. Thus, when the treatment head portion 12 is viewed in the axial direction, the area of the treatment head portion 12 in the axial direction can be reduced by having a shape having a plurality of corners K. In addition, by arranging the surgical elements 81a to 81d at positions corresponding to the corners K, it is possible to set the operating area of the surgical elements 81a to 81d by the motor 32 to the maximum. Thereby, the area | region which can provide the stimulus by the operation element 81a-81d can be expanded.

  (2) Further, in this configuration in which the surgical elements 81a to 81d are divided into two groups and operate integrally (interlocked), the surgical head part 12 is configured to have a relatively simple substantially rectangular shape when viewed in the axial direction. The significance is great.

  (3) The surgical elements 81a to 81d are configured to be rotatable about the center of the connecting shaft 47 that is the second axis shifted from the first axis centers P1 to P4 (centered on the final output shaft 56). By adopting such a configuration, the operation area is expanded and a wider range compared to the case where the centers P1 to P4 and the center of the connecting shaft 47 are on the same axis and the surgical elements 81a to 81d are rotated. Can be stimulated.

In addition, you may change embodiment of this invention as follows.
In the above embodiment, the treatment head portion 12 is configured in a polygonal shape that is a substantially quadrangular shape having four corners K when viewed in the axial direction. However, other shapes such as a triangular shape or a shape that is a pentagon or more are appropriately used. It may be changed. Note that, as in the above-described embodiment, among the surgical elements 81a to 81d, the surgical elements 81a and 81c perform an interlocking operation such that the scalp is sandwiched, and the surgical elements 81b that are 180 degrees out of phase with the surgical elements 81a and 81c. , 81d, it is desirable that the N-shaped shape (where N is an even number) be used. However, in the above-described embodiment, the surgical elements 81a and 81c and the surgical elements 81b and 81d are revolving motions that are 180 degrees out of phase, and thus the shape of the surgical head portion 12 when viewed in the axial direction is a square shape. In cases other than the shape, the shift (180 degrees in phase) of the circular motion between the surgical elements 81a and 81c and the surgical elements 81b and 81d may be changed as appropriate.

  In the above embodiment, the connection shaft 47 and the final output shaft 56 are configured such that the final output shaft 56 is decentered around the connection shaft 47 at a position where the connection shaft 47 and the final output shaft 56 are displaced in the axis orthogonal direction (plane direction). A configuration in which the connecting shaft 47 and the final output shaft 56 rotate on the same axis may be employed. In this case, the surgical elements 81a to 81d rotate around the arrangement centers (P1 to P4) of the surgical projections 83 of the surgical elements 81a to 81d, so that the surgical elements 81a to 81d and the cover portion 61 are separate. It is desirable to be.

  In the above embodiment, the surgical elements 81a to 81d are configured to operate in a direction (surface direction) orthogonal to the connecting shaft 47 (final output shaft 56). In addition, the surgical elements 81a to 81d are axially moved. You may employ | adopt the structure operated by. With such a configuration, it is possible to give a stimulus that strikes the user's scalp.

  In the above embodiment, the cover portion 61 and the treatment elements 81a to 81d constituting the treatment head portion 12 are integrally formed with a flexible member, but a separate structure may be employed. However, it is desirable that the treatment protrusions 83 of the treatment elements 81a to 81d be formed of a flexible member (elastic member) in any configuration.

  In the above embodiment, four surgical elements 81a to 81d are provided, but the number may be arbitrarily changed. Moreover, although it was set as the structure which provided the treatment processus | protrusion 83 which comprises the operation element 81a-81d 4 each, the number may change arbitrarily, for example, the number of operation processions 83 differs in each operation element 81a-81d. May be. Furthermore, although it was set as the structure which provided three small diameter protrusion 83a in the front-end | tip of each treatment protrusion 83, the number may change arbitrarily, for example, the number of protrusion 83a in each treatment protrusion 83 may differ. Further, a configuration in which the protrusion 83a is omitted may be employed.
