  The plurality of treatment protrusions provided on the treatment element need to have a certain height. This is because, when the height of the treatment protrusion is too low, the treatment protrusion cannot make good contact with the background when used by a person with a large amount of hair. However, if the height of the surgical procession is too high, the distal ends of the surgical procession are gathered together when elastically deformed, and the treatment process can be performed only in a narrow area. There is a risk of hardly moving. Although this problem can be solved to some extent by increasing the interval between the treatment protrusions, another problem arises that the size of the treatment element increases.

The cam frame portion 43 is formed long in the left-right direction, and the inner dimension length in the left-right direction is equal to or larger than the outer diameter D of the rotation locus of the cam protrusion 41. The shaft portions 45 and 45 are pivotally supported by a mounting case 46 so as to be rotatable. The cam projection 41 is located in the cam frame portion 43. Accordingly, when the rear drive gear 26 rotates, the cam protrusion 41 moves circularly, and the cam frame portion 43 extracts only the movement in the front-rear direction of the rotational movement of the cam protrusion 41, so that the intermediate The mounting body 42 swings back and forth around the shaft portions 45 and 45.

  A treatment body 47 is attached to the intermediate attachment body 42. The treatment body 47 includes a horizontally long connecting portion 48 and a pair of attachment portions 49, 49 provided so as to protrude from both left and right ends of the connecting portion 48. The center of the connecting portion 48 is fixed to the intermediate mounting portion 44 of the intermediate mounting body 42. Further, treatment element main bodies 51 and 51 are connected to the attachment portions 49 and 49, respectively. Then, the reciprocating treatment element 6 is constituted by the treatment element main bodies 51 and 51 and the attachment portions 49 and 49.

  As shown in FIGS. 13 to 18, the cylindrical portion 55 has a lower cylindrical portion 101 at the lower portion, and a reduced cylindrical portion 102 that is slightly reduced in diameter upward is integrally provided on the upper portion of the lower cylindrical portion 101. As shown in FIG. 14, a plurality of treatment protrusions 56 are provided on the cylindrical portion upper surface 55 </ b> A that is the upper surface of the reduced cylindrical portion 102 so as to protrude from each other at regular intervals in the circumferential direction. Further, a substantially hemispherical tip surface 56A is formed on the upper portion (tip) of the treatment projection 56, and the small projections 57 are projected from the tip surface 56A at equal intervals in the circumferential direction. The treatment protrusion 56 is solid.

  A cylindrical protrusion tip 103 is provided on the upper part of the treatment protrusion 56, and a protrusion base part 104 whose upper end side (tip side) is thin is provided on the lower part of the treatment protrusion 56. An enlarged thick portion 105 that expands from the center side of the cylindrical portion 55 toward the upper surface of the cylindrical portion 55 is formed in the protruding base portion 104 at the lower end of the protruding distal end portion 103. That is, an enlarged thick portion 105 whose cross-sectional area expands from the upper end 104A of the protrusion base portion 104 toward the center side of the lower cylindrical portion 55 is formed, and the protrusion base portion 104 corresponds to the enlarged thick portion 105. It is formed thicker than the protrusion tip 103. As shown in FIGS. 13 and 16, the plurality of protrusion bases 104 are formed so as to be separated from each other toward the distal end side by the enlarged thick part 105. The protrusion tips 103, 103, 103 of the treatment protrusions 56, 56, 56 are substantially parallel to each other.

  Further, the length of the projection base 104 is not less than 1/3 and 2 minutes with respect to the length from the cylindrical upper surface 55A to the tip of the small projection 57 at the center of each of the treatment projections 56, 56, 56. 1 or less of these is preferable. If the length is less than one-third, the effect of preventing deformation of the treatment protrusion 56 toward the center by the enlarged thickness portion 105 may not be sufficiently obtained, while the length is 2 This is because if the ratio exceeds one half, the interval between the treatment protrusions 56 becomes narrow on the base end side, and it may be difficult to enter between the hairs.

  Furthermore, the left and right side portions 105S and 105S of the enlarged thick portion 105 are substantially straight and obliquely arranged with respect to the central axis of the treatment projection 56, and the upper edge 105U of the enlarged thick portion 105 is formed. To the outer periphery of the upper surface 55A of the cylindrical portion, the left and right side portions 105S, 105S are formed to be narrower. On the other hand, the outer peripheral side of the cylindrical portion 55 of the treatment projection 56 is formed in a straight line and is substantially continuous with the upper end side surface of the reduced cylindrical portion 102. The center of the upper surface 55A of the cylinder part is formed at substantially the same height as the periphery 55S of the upper surface 55A of the cylinder part.

  Next, the drive mechanism of the rotary treatment element 5 will be described. As shown in FIGS. 3 and 10, cam receiving portions 61 are provided on the lower surfaces of the central gears 32L and 32R and the outer gears 33L and 33R at positions eccentric from the rotation centers. These cam receiving portions 61 are formed inside the cylindrical portion.

  The rotary treatment element 5 includes an attachment shaft 65 and the treatment element body 51. A cam portion 66 that is inserted into the cam receiving portion 61 is formed on the mounting shaft 65. The cam portion 66 is formed in a spherical shape. An attachment portion 67 for attaching the treatment element body 51 is formed below the attachment shaft 65.

  As shown in FIGS. 17 and 18, an insertion hole 111 for inserting the mounting portion 67 of the mounting shaft 65 is formed at the center of the bottom surface of the cylindrical portion 55, and a plurality of (in the circumferential direction, equally spaced ( Three (notched) grooves 112 are provided radially. Further, an enlarged diameter portion 111A is provided on the proximal end side of the insertion hole 111, and the outer surface of the enlarged diameter portion 111A is formed by a part of a spherical surface. Further, a retaining portion 67A is provided in the mounting portion 67 corresponding to the enlarged diameter portion 111A. Therefore, when the attachment portion 67 is inserted into the insertion hole 111, the retaining portion 67A is engaged with the enlarged diameter portion 111A, and a retaining state is obtained.

  Further, a swing engagement portion 68 is formed at the approximate center in the length direction of the mounting shaft 65. The swing engaging portion 68 is formed thicker than the upper and lower portions, and its outer surface is formed into a substantially spherical surface. A shaft insertion hole 69 is formed through the swing engagement portion 68 so as to be orthogonal to the axial direction of the mounting shaft 65, and a support shaft 70 is inserted through the shaft insertion hole 69. . As shown in FIG. 10, the shaft insertion hole 69 has an enlarged portion 71, 71 whose central portion is slightly wider than the diameter of the support shaft 70 and whose inner diameter increases from the central portion toward the outside. Is formed. That is, the shaft insertion hole 69 is formed in a drum shape. Further, the swing engagement portion 68 is supported by a spherical receiving portion 73 formed on the mounting case 72 so as to be swingable.

  Therefore, when the central gears 32L, 32R and the outer gears 33L, 33R rotate, the tip of the mounting shaft 65 rotates in a circle with the swing engaging portion 68 as the center of swing.

  In the rotary treatment element 5 described above, the projection base 104 of the treatment projection 56 is formed thicker than the projection tip portion 103 on the distal end side, so that the treatment projection 56 is adapted to a person with a large amount of hair. Even if the height is set, the treatment protrusions 56 are elastically deformed during rotation and hardly gather on the center side, and care for the scalp is performed in a state where a plurality of the treatment protrusions 56 are kept at intervals. Can do. Particularly, since the enlarged thick portion 105 is provided on the center side of the protrusion base 104, deformation of the treatment protrusion 56 toward the center can be suppressed during the rotational movement.

  As shown in FIG. 10, the attachment case 72 to which the rotary treatment element 5 is attached has a spindle attachment hole 74 that is an attachment part to which the end of the spindle 70 is inserted and attached. The mounting case 72 is composed of two split cases 72A and 72A, and the split cases 72A and 72A are assembled in a state where the mounting shaft 65 is assembled together with the support shaft 70.

  FIG. 12 is a view for explaining the operation of the rotary treatment element 5 and the reciprocation treatment element 6. As shown in the figure, the left and right central gears 32L and 32R, the left and right outer gears 33L and 33R, and the left and right reciprocating treatment elements 6 and 6 are symmetrical with respect to the symmetry plane 81. In position. Further, on the line representing the symmetry plane 81, the lengths of virtual lines 132L, 132R, 133L, 133R connecting the centers of the gears 32L, 32R, 33L, 33R and the reference point 82 are substantially equal, and the symmetry plane 81 Is equal to the imaginary lines 132L and 132L of the left and right central gears 32L and 32R, and the imaginary lines 132L and 132L and the imaginary lines 133L and 133R of the left and right outer gears 33L and 33R are formed. The angle θ4 is equal. Further, as described above, the gears 32L, 32R, 33L, and 33R have the same diameter and the same number of teeth. The angle θ4 is slightly more than twice the angle θ3. Specifically, in this embodiment, the angle θ3 is 9 degrees and the angle θ4 is 21 degrees. The angle θ4 is slightly larger than the angles θ1 and θ2. Each spindle 70 is arranged along the direction of the virtual lines 132L, 132R, 133L, 133R. Further, the central axes 136L and 136R of the bevel gears 36L and 36R are inclined at an angle θ around the virtual axes 133L and 133R.

  The rotary treatment element 5 and the reciprocation treatment element 6 are arranged such that the left part (first part) 83L and the right part (second part) 83R located on the left and right of the symmetry plane 81 are plane-symmetric. At the same time, it operates symmetrically. Specifically, all the rotary treatment elements 5, 5, 5, 5 are on the extension lines of the virtual lines 132 L, 132 R, 133 L, and 133 R and at positions farthest from the reference point 82. Can be simultaneously located at the reference position where the tip of the lens is located. At this time, the distal ends of the reciprocating treatment elements 6 and 6 are in an outer position (rear position) where they reciprocate. From this point, when the electric motor 3 operates, the tips of the rotary treatment elements 5 and 5 of the left portion 83L rotate clockwise at the same speed, and the tips of the rotation treatment pieces 5 and 5 of the right portion 83R turn counterclockwise. Rotate at the same speed. “△” is attached to the position where the rotary treatment elements 5 and 5 are rotated 90 degrees from the reference position, “◯” is attached to the position rotated 180 degrees, and “X” is attached to the position rotated 270 degrees. In addition, “●” is attached to the reference position rotated 360 degrees and returned. In addition, “●”, “△”, “◯”, and “×” are attached to positions corresponding to the reciprocating treatment element 6. That is, at the position “Δ” where the rotary treatment elements 5 and 5 are rotated 90 degrees from the reference position, the reciprocating treatment element 6 is at an intermediate position, and at the position where the rotation treatment elements 5 and 5 are rotated 180 degrees, The reciprocating treatment element 6 is at the inner position (front position), the rotation treatment elements 5 and 5 are rotated at 270 degrees, the reciprocation treatment element 6 is at an intermediate position, and the rotation treatment elements 5 and 5 are rotated at 360 degrees. The reciprocating treatment element 6 is in the outer position. The left and right reciprocating treatment elements 6 and 6 perform the same operation. Accordingly, the rotary treatment element 5 and the reciprocation treatment element 6 are driven so that the mutual tips approach between “●” and “◯”, and the mutual tips separate from “◯” to “●”. To drive.

  As described above, in the left portion 83L and the right portion 83R, the treatment elements 5 and 6 are arranged in plane symmetry and operate in plane symmetry.

  When the electric motor 3 is driven by a switch (not shown) and the treatment elements 5 and 6 are applied to the scalp, the tip of the rotary treatment element 5 moves circularly, and the tip of the reciprocation treatment element 6 reciprocates back and forth. And you can massage the scalp. At this time, the scalp can be massaged as if the two center rotary treatment elements 5 and 5 are the index fingers of both hands, and the right and left rotation treatment elements 5 and 5 are the middle fingers of both hands. In addition, the reciprocating treatment element 6 at a position away from these four rotation treatment elements 5, 5, 5, and 5 can massage the scalp as if it were the thumbs of both hands. As a result, the rotary treatment element 5 and the reciprocation treatment element 6 repeat the operations of approaching and moving away from each other while the rotation treatment element 5 rotates, and as a whole, it is as if the scalp is grasped by the hand. It is possible to perform a massage.

  In addition, since the tip of the rotary treatment element 5 rotates in the opposite direction synchronously between the left side portion 83L and the right side portion 83R, the scalp care device 1 does not shake with the rotary treatment element 5 applied to the scalp and is stable. To make a circular motion. That is, if all the rotary treatment elements 5 are applied to the scalp while being rotated in the same direction, a force that moves the scalp care device 1 in the counter-rotation direction is generated by the reaction of the generated torque. And in order to suppress this, a user must hold | grip firmly so that the said scalp care device 1 may not move.
