First Embodiment
Hereinafter, a scalp care device according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 4.
As shown in FIG. 1, the scalp care device 10 in the present embodiment includes a cylindrical housing 11 having an opening 11 a.

As shown in FIG. 2, a first drive motor 17 as a first rotation drive unit is built in the housing 11, and the rotation shaft 17 a of the first drive motor 17 is used as a first support member. The first rotary plate 13 is connected. Further, the first drive motor 17 is electrically connected to the power supply unit 18 and the control unit 19 built in the housing 11. Further, the power supply unit 18 and the control unit 19 are electrically connected, and the control unit 19 is electrically connected to the power switch 20 and the direction change switch 21 disposed on the side surface of the housing 11.

As shown in FIGS. 2 and 3, the first rotary plate 13 has a disk shape in a plan view, and is accommodated in the housing 11 so as to be located in the vicinity of the opening 11a. A cylindrical treatment element 12 is provided on the first rotary plate 13 so as to protrude from the opening 11 a to the outside of the housing 11. The proximal end 12 a of the treatment element 12 is supported at a position slightly inward from the edge of the attachment surface 13 a of the first rotary plate 13, and the tip 12 b of the treatment element 12 is of the first rotary plate 13. It is located on the central axis L1. That is, the treatment element 12 is provided so as to be inclined toward the central axis L1 of the first rotary plate 13 from a position slightly closer to the inner diameter side from the edge of the first rotary plate 13. The treatment element 12 is cantilevered on the first rotary plate 13.

The angle θ between the axis L2 of the treatment element 12 and the central axis L1 of the first rotary plate 13 is set to be in the range of 15 ° to 60 °. The angle θ is more preferably in the range of 30 ° to 45 °. Further, the tip 12b of the treatment element 12 has a hemispherical shape, and the tip 12b includes a spherical (smooth convex) treatment surface 12c to be treated in contact with the scalp of the treatment element 12. Furthermore, the central axis L1 intersects the treatment surface 12c at a position separated from the attachment surface 13a. The treatment surface 12 c has a center that coincides with the central axis L 1 of the first rotary plate 13. The center of the treatment surface 12c may be referred to as a rotation center, and is, for example, a point of the tip 12b of the treatment element 12 which is most distant from the attachment surface 13a on the central axis L1.

As shown in FIG. 4, the treatment element 12 includes a core 14 disposed inside the treatment element 12, a first elastic member 15 covering the outer surface of the core 14, and a first elastic member 15. And a second elastic member 16 for covering the The core portion 14 is made of, for example, a molded article of iron, plastic or the like. The first and second

elastic members

15 and 16 are made of an elastic material such as rubber, and the hardness (for example, 15 to 25 degrees) of the second elastic member 16 is the hardness (for example, 5) of the first elastic member 15. Higher than ~ 15 degrees). The hardness of the first and second

elastic members

15 and 16 is lower than the hardness (for example, 70 to 90 degrees) of the core portion 14. Further, the thickness of the second elastic member 16 is thinner than the thickness of the first elastic member 15. Thus, the rigid core 14 plays the role of bone in human fingers, and the first elastic member 15 functioning as the inner elastic layer plays the role of fat in human fingers, and the outermost layer or skin layer The second elastic member 16 which functions as a skin plays a role of a human finger. Therefore, the treatment element 12 is shaped so as to give the scalp a tactile sensation resembling human fingers. In the above description, the hardness display measured in accordance with JIS K 6253 durometer type A is exemplified as a numerical value of hardness.

When the power switch 20 is turned on, an input signal is sent to the control unit 19. In response to the input signal from the power supply switch 20, the control unit 19 transmits a command signal for activating the power supply unit 18. The power supply unit 18 is activated according to a command signal from the control unit 19 and supplies power to the first drive motor 17 to drive it. Then, the first drive motor 17 receives power supply from the power supply unit 18 and rotates the first rotary plate 13 (for example, clockwise direction of arrow R1 shown in FIG. 3).

When the direction switch 21 is pressed while the first rotary plate 13 is rotating, an input signal is sent from the direction switch 21 to the controller 19. In response to an input signal from the direction switching switch 21, the control unit 19 controls the first drive motor 17 to rotate the first rotary plate 13 in the reverse direction (for example, the arrow R2 shown in FIG. 3). Counterclockwise direction).

Next, a usage example of the scalp care device 10 configured as described above will be described.
The user holds the scalp care device 10 so that the tip 12b side of the treatment element 12 faces the scalp, and operates (turns on) the power switch 20. Then, while rotating the first rotary plate 13 by the first drive motor 17, the tip 12 b of the treatment element 12 is pressed against the scalp. Here, the treatment element 12 is provided so as to be inclined toward the central axis L 1 of the first rotary plate 13 from a position slightly closer to the inner diameter side from the edge of the first rotary plate 13. The pressing force that the scalp receives from the treatment element 12 is a component of the central axis L1 (for example, a vector orthogonal to the scalp) and a radial component (for example, on the surface of the scalp) that changes as the first rotary plate 13 rotates. Combined with the vector). Further, due to the contact with the treatment surface 12c of the treatment element 12, the scalp and the treatment surface 12c are deformed by their own elasticity and become in surface contact. Therefore, in a state where the first rotary plate 13 is rotating, the pressing force of the treatment element 12 is dispersedly applied to the entire contact site (contact surface) of the scalp in contact with the treatment surface 12c. Ru. Furthermore, the center of the treatment surface 12 c of the treatment element 12 is set to coincide with the central axis L 1 of the first rotary plate 13. Therefore, even if the treatment surface 12c of the treatment element 12 comes into contact with the scalp while the first rotary plate 13 rotates, the center of the treatment surface 12c of the treatment element 12 abuts centrally on one point of the scalp. There is no possibility that the contact point between 12 and the scalp will be shaken. Therefore, stimulation can be concentrated on one point of the scalp (contacted area) by the feeling of acupressure. In addition, since the direction of the radial component of the pressing force changes periodically and periodically by rotation, the pressing force "vibrates" for each point in the contact surface of the scalp. Therefore, the rotation of the inclined treatment element 12 contributes to the improvement of the massage effect.

The following effects can be obtained in the above embodiment.
(1) The treatment element 12 is provided on the first rotary plate 13 provided in the scalp care device 10, and the first drive motor 17 is connected to the first rotary plate 13.

(2) The treatment element 12 comprises the core portion 14, the first elastic member 15 and the second elastic member 16, and the hardness of the second elastic member 16 is greater than that of the first elastic member 15. The hardness of the first and second

elastic members

15 and 16 is lower than the hardness of the core portion 14. Therefore, by arranging the core portion 14 inside the treatment element 12, the strength (rigidity) of the treatment element 12 itself can be increased compared to a configuration in which the core portion 14 is not provided inside the treatment element 12. it can. Further, by covering the outer surface of the core portion 14 with the first elastic member 15 and the second elastic member 16, the treatment surface 12 c of the treatment element 12 becomes the second elastic member 16, so contact with the scalp is It becomes soft and elasticity can be given to the contact area of the scalp in contact with the treatment surface 12 c of the treatment element 12. Therefore, while being able to suppress that the treatment surface 12c of the treatment child 12 slips with respect to the scalp, the treatment child 12 can be stuck with respect to the scalp.

(3) The treatment element 12 is further provided with a second elastic member 16 covering the first elastic member 15, and the hardness of the second elastic member 16 is higher than the hardness of the first elastic member 15. It has become. Therefore, by further covering the first elastic member 15 with the second elastic member 16 higher than the hardness of the first elastic member 15, the durability of the first elastic member 15 can be improved, and the treatment The elasticity of the outermost layer in contact with the scalp in the child 12 can be maintained.

(4) The treatment element 12 is provided so as to extend in a direction inclining toward the central axis L1 of the first rotary plate 13. Therefore, compared with the case where the treatment element provided parallel to the central axis L1 of the first rotary plate 13 presses the scalp, pressing force can be applied to the scalp in various directions, and the massage effect on the scalp is It can be improved.

(5) The tip 12b of the treatment element 12 is formed in a hemispherical shape, and the treatment surface 12c is formed in a spherical surface. Therefore, when the scalp is treated by the treatment element 12 while the first rotary plate 13 rotates, the scalp can be treated while the treatment surface 12c of the treatment element 12 is in smooth contact with the scalp.

(6) The center of the treatment surface 12 c of the treatment element 12 is set to coincide with the central axis L 1 of the first rotary plate 13. Therefore, since the center of the treatment surface 12c is concentrated and abuts on a point on the scalp, and the contact point between the treatment element 12 and the scalp is not shaken, the stimulation can be concentrated on a point on the scalp and feel of finger pressure Can be obtained further. In addition, when the center of the treatment surface 12c is in contact with a point on the scalp with a concentration, the first rotary plate 13 rotates while the scalp is treated by the treatment element 12, the hair is caught by the treatment element 12 and It is possible to suppress the
