For this reason, the imaginary surface LX1 formed by connecting the distal end positions of the first treatment protrusions 83 has a curved (spherical) shape as shown in FIG. The virtual surface LX1 is formed so as to have a concave shape on the base surface 82a side, which is the proximal end side of the treatment protrusion 83.

  Further, one flat surface portion 83c of the first to sixth flat surface portions 83c to 83h constituting the large protrusion 83a is configured to face the center P1 to P4 side of each surgical element base portion 82. The first to sixth plane portions 83c to 83h are formed to have substantially the same shape. For this reason, it forms so that the length (= length of a side part) Ha1-Ha6 in the orthogonal direction of the extending direction in the same height of each plane part 83c-83h may become the same length (FIG.19 (b) )reference).

  As shown to Fig.19 (a), the 2nd treatment processus | protrusion 84 is provided in total 16 pieces, respectively, 4 pieces in each of the treatment elements 81a-81d. That is, each of the surgical elements 81a to 81d is provided with a total of 32 first and second surgical projections 83 and 84, eight in total.

  The second treatment protrusion 84 is configured to be disposed between the first treatment protrusions 83 in the circumferential direction. For this reason, the first treatment protrusions 83 and the second treatment protrusions 84 are alternately arranged in the circumferential direction.

Moreover, the 2nd treatment protrusion 84 is arrange | positioned on the concentric circle centering | focusing on the centers P1-P4 of the treatment element base part 82, ie, it is comprised so that the distance from each center P1-P4 may become the same.
As shown in FIGS. 19 (a) and 19 (c), the large protrusion 84a constituting the second treatment protrusion 84 includes substantially rectangular first to third plane portions 84c to 84e and substantially trapezoidal fourth to sixth. The flat portions 84f to 84h are alternately arranged in the circumferential direction to form a substantially hexagonal shape when viewed in the vertical direction (viewed in the extending direction). The large protrusion 84a is configured to have a tapered shape.

  Further, one flat surface portion 84c of the first to third flat surface portions 84c to 84e constituting the large protrusion 84a faces the center P1 to P4 side of each surgical element base portion 82 as shown in FIG. Configured as follows.

  The first to third plane portions 84c to 84e are formed to have substantially the same shape. For this reason, it forms so that the length (= length of a side part) Hb1-Hb3 in the orthogonal direction of the extending direction in the same height of each plane part 84c-84e may become the same length. The fourth to sixth plane portions 84f to 84h are formed to have substantially the same shape. For this reason, the lengths (= side lengths) Hb4 to Hb6 in the orthogonal direction of the extending direction at the same height of each of the flat portions 84f to 84h are formed to be the same length. Further, the lengths Hb1 to Hb3 of the first to third plane portions 84c to 84e are configured to be shorter than the lengths Hb4 to Hb6 of the fourth to sixth plane portions 84f to 84h. For this reason, even if it arrange | positions between the 1st treatment protrusions 83 the 1st plane part 84c side which is the center P1-P4 side, it becomes possible to provide sufficient space | interval. Moreover, each large protrusion 83a is comprised so that it may become the same length.

  Three small protrusions 84b extending in the same direction as the large protrusion 84a are formed at the tip of the large protrusion 84a. These small protrusions 84b are configured to have the same length. And as mentioned above, it forms in the treatment element base part 82 formed so that the arrangement | positioning center CP side becomes low, and it forms so that the front-end | tip position of the 2nd treatment processus | protrusion 84 may become low as arrangement | positioning center CP. For this reason, the imaginary surface LX2 formed by connecting the second treatment protrusions 84 has a curved shape as shown in FIG. The virtual surface LX2 is formed so as to have a concave shape on the base surface 82a side, which is the proximal end side of the treatment protrusion 84.

  Further, as shown in FIG. 16, the tip position of the second treatment projection 84 (tip position of the small projection 84b) is lower than the tip position of the first treatment projection 83 (tip position of the small projection 83b) by S1. Configured to be

In addition, the second treatment protrusion 84 is formed at a position (outer peripheral side) that is farther from the centers P1 to P4 than the first treatment protrusion 83.
The second treatment protrusion 84 is formed to be thinner than the first treatment protrusion 83 and has a lower rigidity than the first treatment protrusion 83.

  In the scalp care device 10 configured as described above, when the switch operating member 22 is pressed by the user, the switch 24a is switched on and off, and the motor 32 is driven to operate the surgical elements 81a to 81d. Rotates. Therefore, when the driving force of the motor 32 is transmitted through the gears 41 to 46, the surgical elements 81a to 81d of the surgical head unit 12 are operated around the connecting shaft 47. When the treatment protrusion 83 (protrusion 83a) of the treatment elements 81a to 81d is brought into contact with the scalp, the user's scalp is moved in accordance with the movement of the treatment protrusion 83, and the scalp is to be cared for (massaged). Become. At this time, the surgical elements 81 a to 81 d are operated to move the scalp in one direction from the operation of the gears 41 to 46 and the arrangement relationship of the rotation base 55.

  Here, the rotation operation (action) of the surgical elements 81a to 81d provided in the scalp care device 10 will be described in detail mainly with reference to FIG. In addition, in FIG. 9, the top view when the scalp care apparatus 10 is seen from the downward direction is shown. In FIG. 9, the direction orthogonal to the paper plane corresponds to the vertical direction, and the horizontal direction in the figure is the horizontal direction of the scalp care device 10, and the vertical direction in the figure is the front-back direction.

  The surgical elements 81a to 81d are connected to a connecting shaft 47 arranged in a substantially square shape in plan view via a rotary base 55, a final output shaft 56, and a surgical element base 71 as shown in FIGS. Has been. Among them, the surgical elements 81a and 81b that rotate counterclockwise adjacent to each other in the front-rear direction and in the axis orthogonal direction (direction orthogonal to the extending direction) have centers P1 and P2 of the surgical element base portions 82 respectively connected to the connecting shafts. Rotate with a phase shift of 180 degrees around 47. Similarly, in the surgical elements 81c and 81d that rotate clockwise in a direction orthogonal to the axis (a direction orthogonal to the extending direction), the centers P3 and P4 of the surgical element base portions 82 are centered on the connecting shafts 47. And rotate with a phase shift of 180 degrees from each other. Further, in the surgical elements 81a and 81c (surgical elements 81b and 81d) adjacent in the left-right direction, the centers P1 and P3 (centers P2 and P4) of the surgical element base portion 82 are perpendicular to the bisector L. 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. An 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 addition, virtual surfaces LX1 and LX2 formed by connecting the first and second treatment protrusions 83 and 84 are curved (spherical) and formed so as to be lower toward the arrangement center CP side of the treatment elements 81a to 81d. The For this reason, the first treatment protrusions 83 are in contact with the scalp substantially at the same time, and the first treatment protrusions 83 can apply stimulation to the scalp with an equivalent contact pressure. Further, the second treatment protrusion 84 is lightly contacted by bringing the protrusion 83 into close contact until the relatively high first treatment protrusion 83 comes into contact with the first treatment protrusion 83 and is bent. In this state, by operating the surgical elements 81a to 81d as described above, the surgical protrusion 83 that is in close contact with the scalp makes the contact force between the surgical protrusions 83 equal to each other and provides a scalp care effect while lightly contacting the scalp. The cleaning effect is imparted by the operation of sliding on the scalp with the second treatment projection 84 having the same contact color of the treatment projection 84 can.

Next, characteristic effects of the present embodiment will be described.
(1) In the treatment head part 12, virtual surfaces LX1 and LX2 formed by connecting the distal end positions of the treatment protrusions 83 and 84 in the plurality of treatment elements 81a to 81d are concave on the proximal end side of the treatment protrusions 83 and 84. It is configured to have a spherical shape. By adopting such a configuration, the contact pressure of the scalp for each of the treatment protrusions 83 and 84 can be made substantially equal, so that the unevenness of the scalp care effect can be suppressed and the scalp care effect can be imparted more suitably. it can. Moreover, the cleaning effect by the 2nd treatment protrusion 84 can also be provided suitably.

  (2) The treatment head portion 12 is lowered toward the arrangement center CP side of the treatment elements 81a to 81d by inclining the base surface 82a on which the treatment projections 83 and 84 are formed, and is concave on the proximal end side of the treatment projections 83 and 84. It is comprised so that the spherical shape which makes | forms may be made. Thus, since it can be set as a spherical shape without changing the length etc. of the treatment protrusions 83 and 84, the rigidity for every treatment protrusion 83 and 84 can be made uniform.

(3) Since the treatment projections 83 and 84 are configured so that all the extending directions thereof are directed in the same direction, it is easy to mold with the mold.
(4) Here, since the axial direction of the connecting shaft 47 and the extending direction of the treatment protrusions 83 and 84 coincide with each other, the treatment elements 81a to 81d are orthogonal to the extending direction of the treatment protrusions 83 and 84, And it drives in the direction orthogonal to the axial direction of the connecting shaft 47 as an output shaft. In this way, the surgical elements 81a to 81d can be operated with a simple configuration.

  (5) The relatively low second treatment protrusion 84 is configured to have lower rigidity than the relatively high first treatment protrusion 83. By setting it as such a structure, the scalp can be wash | cleaned, suppressing giving an excessive load to a scalp.

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, a surgical element 81b that performs an interlocking operation such that the scalp is sandwiched between the surgical elements 81a and 81c and is 180 degrees out of phase with the respective 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. 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. Moreover, you may employ | adopt the structure which slide-operates not only rotation operation but surgical element 81a-81d in the direction which cross | intersects the treatment protrusions 83 and 84 (the said connection shaft 47).

  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 provides the 1st treatment protrusion 83 and the 2nd treatment protrusion 84 which comprise the treatment element 81a-81d, respectively, the number may be changed arbitrarily. For example, at least one of the first treatment protrusion 83 and the second treatment protrusion 84 may be different for each of the treatment elements 81a to 81d. Further, although three small projections 83b and 84b having a smaller diameter are provided at the tips of the first treatment projection 83 and the second treatment projection 84, the number thereof may be arbitrarily changed, for example, the first treatment projection 83. In addition, the number of small protrusions 83b and 84b in the second treatment protrusion 84 may be different. Moreover, you may employ | adopt the structure which abbreviate | omitted the said small protrusion 83b, 84b.

  In the above embodiment, the second treatment protrusion 84 is made thinner than the first treatment protrusion 83 so as to have low rigidity (easy to bend), but the same rigidity may be used, and the second treatment protrusion 84 may be The first treatment protrusion 83 may be more rigid than the first treatment protrusion 83. In addition, as a low-rigidity method, a configuration with a low rigidity or a high rigidity by changing the material may be employed.

In the above embodiment, two types of first and second treatment protrusions 83.84 having different heights are used, but a configuration including three or more types of treatment protrusions having different heights may be employed.
In the above embodiment, by increasing the height of the base surface 82a of the base portion 82 toward the outside, the curved surface connecting the distal end positions of the treatment protrusions 83 and 84 is curved so that it is depressed toward the center side. Although configured, the present invention is not limited to this. For example, as shown in FIG.
In the above embodiment, the extending directions of the treatment protrusions 83 and 84 are configured to be the same, but the present invention is not limited to this. For example, as shown in FIG. 20, a configuration in which the treatment protrusions 83 and 84 are extended so as to be orthogonal to virtual surfaces LX1 and LX2 formed by connecting the distal end positions of the treatment protrusions 83 and 84 may be employed. In this case, a configuration may be adopted in which driving is performed in a direction orthogonal to the extending direction of the treatment protrusions 83 and 84, or driving in parallel with the virtual surfaces LX1 and LX2. For example, by adopting a configuration in which driving is performed in parallel with the virtual planes LX1 and LX2, the operation becomes parallel to the scalp. For this reason, the treatment intervals by the treatment protrusions 83 and 84 can be uniformly applied to the scalp, and more preferably a cleaning effect and a scalp care effect can be provided.
