The motor 8 has a speed reduction mechanism (not shown), and the motor shaft 8A is rotated by decelerating the rotation at a predetermined speed reduction ratio. The eccentric distance between the motor shaft 8A of the motor 8 and the eccentric shaft 9A of the crank mechanism 9 is F. Therefore, when the motor shaft 8A of the motor 8 rotates, the rotation of the motor shaft 8A is converted into a reciprocating motion by the crank mechanism 9 and the connecting rod 10, and the central portion of the substrate 3 is moved to the axis A by the connecting rod 10. Reciprocate up and down. Further, a battery case 11 for accommodating a battery (not shown) is provided in the cover 6, and a switch 12 for operating the motor 8 is provided on the surface of the cover 6.

An edge 3B of the substrate 3 is arranged so that one side surface 3A is along the other side surface of the frame body 5, and a sliding long hole 13 as a sliding portion is centered on the axis A on the edge 3B. Are provided at equal intervals, and at four locations in the embodiment. Incidentally, the longitudinal direction of the sliding long hole 13 is formed in a radial direction with the axis A as the center, and a protrusion 14 serving as a sliding receiving portion erected on the other side surface of the frame body 5 includes: The sliding long hole 13 is inserted.

Furthermore, a large width portion 14A is provided at the upper end of the protrusion 14, and the large width portion 14A is disposed slightly above the other side surface 3C of the substrate 3, so that the sliding long hole 13 is provided with the large width portion 14A. On the other hand, the protrusion 14 can be prevented from coming off.

  Next, the effect | action is demonstrated about the said structure. When washing hair, the user first holds the brush device 1 and presses the tip 4B of the protrusion 4 of the brush portion 2 against the scalp G. At this time, the tip 4B of the protrusion 4 is pressed against the scalp G with a light force. Next, when the switch 12 is closed, power is supplied from a battery (not shown) to operate the motor 8 and rotate the motor shaft 8A. Along with this rotation, the crank mechanism 9 attached to the motor shaft 8A rotates, and the crank mechanism 9 and the connecting rod 10 connected to the eccentric shaft 9A of the crank mechanism 9 rotate the motor shaft 8A. Is converted into a reciprocating motion, and the substrate 3 connected to the connecting rod 10 reciprocates at the center along the axis A. The deformation with an amplitude of 2F is repeated between the bent curved convex states.

Then, as shown in FIG. 5, when the eccentric shaft 9A of the crank mechanism 9 is above the motor shaft 8A, the substrate 3 itself is bent and the substrate 3 itself is bent by being pulled up by the connecting rod 10. by is lifted, the edge 3B side of the substrate 3 is sliding with respect to the frame 5. By this sliding, the inner end 13 </ b> A side of each sliding long hole 13 is moved inward, so that the outer end 13 </ b> B moves so as to approach the protruding portion 14 side. As a result, the substrate 3 is in a curved concave state bent upward with the center at the top. Of the protrusions 4 formed integrally with the substrate 3 so as to be orthogonal to the one side surface 3A of the substrate 3, at least the base end 4A is accompanied by the bending of the one side surface 3A of the substrate 3. Thus, by moving integrally while maintaining an orthogonal state with the one side surface 3A, the tips 4B of the plurality of projections 4 are closed, that is, the axes D at least at the base ends 4A of the plurality of projections 4 are inward. It will move in the direction. In fact, as described above, the tip 4B of the protrusion 4 is always in contact with the scalp G because the tip 4B of the protrusion 4 is pressed against the scalp G with a light force. As a result, among the protrusions 4 formed of a flexible synthetic resin such as a flexible elastomer, at least the base end 4A formed thicker in the protrusions 4 formed on the outer peripheral side of the substrate 3 is slightly However, the tip 4B side that is formed thinly contacts the scalp G in a largely bent state, while substantially deforming and maintaining a state substantially orthogonal to the one side surface 3A of the substrate 3. It will be. Then, the motor 8 rotates in this way and the substrate 3 of the brush portion 2 bends upward, so that the protrusion 4 moves inward while in contact with the scalp G. At the same time that the scalp G is massaged by the tip 4B of the protrusion 4, not only the scalp G but also the hair H is washed by a hair wash or the like. In addition, as described above, the pressing force of the brush part 2 to the scalp G and the tip 4B of the protrusion 4 bend in accordance with the movement of the protrusion 4, so that the scalp G is softly massaged with a touch. And will be washed.

Thereafter, when the eccentric shaft 9A of the crank mechanism 9 is rotated downward from the top dead center, the substrate 3 is pushed and deformed gradually by the connecting rod 10, and as shown in FIG. It becomes the curved convex state bent downward. In this process, together with the substrate 3 itself is bent by being be pushed by the connecting rod 10, the substrate 3 by itself is pressed, the edge 3B side of the substrate 3 is sliding with respect to the frame 5. Since the substrate 3 is deformed from the state shown in FIG. 5 to the state shown in FIG. 6 through the state shown in FIG. After the outer end 13B side is pushed outward, the inner end 13A slides so as to approach the protrusion 14 side (FIG. 5 → FIG. 3), and then the inner end 13A side of each sliding long hole 13 becomes the inner side again. As a result, the outer end 13B slides so as to approach the protrusion 14 side (FIG. 3 → FIG. 6). As a result, the substrate 3 is in a curved convex state bent downward with the center at the bottom. Then, at least the base end 4A of the projections 4 moves integrally with the one side surface 3A substantially in an orthogonal state with the bending of the one side surface 3A of the substrate 3, thereby the plurality of projections. The tip ends 4B of the four projections 4 are opened, that is, the axes D at least at the base ends 4A of the plurality of projections 4 are moved outward. In fact, as described above, the tip 4B of the protrusion 4 is always in contact with the scalp G because the tip 4B of the protrusion 4 is pressed against the scalp G with a light force. As a result, among the protrusions 4 formed of the soft synthetic resin having flexibility, at least the base end 4A formed thick at the protrusion 4 formed at the central portion of the substrate 3 is slightly bent. However, it is substantially not deformed and maintains a state substantially orthogonal to one side surface 3A of the substrate 3, while the thin tip 4B side comes into contact with the scalp G in a largely bent state. . Then, the motor 8 rotates in this way and the substrate 3 of the brush portion 2 bends downward, so that the protrusion 4 moves outward in a state of being in contact with the scalp G. The scalp G is massaged so as to be spread by the tip 4B of the protrusion 4, and at the same time, not only the scalp G but also the hair H is washed by a hair washing agent or the like. In addition, as described above, the pressing force of the brush part 2 to the scalp G and the tip 4B of the protrusion 4 bend in accordance with the movement of the protrusion 4, so that the scalp G is softly massaged with a touch. And will be washed.

  In this way, the rotational force of the motor 8 is converted into a reciprocating motion by the crank mechanism 9 and the connecting rod 10, and the substrate 3 of the brush portion 2 is placed in the state where the projection 4 is kept in contact with the scalp G. 3 and a plurality of projections 4 integrally provided on the substrate 3 are repeatedly bent by sliding in and out of the edge 3B of the substrate 3 with respect to the frame 5 as well as the flexibility and stretchability of the substrate 3. By opening and closing, the scalp G is stimulated to be gripped and spread by the plurality of protrusions 4 and massaged, and the scalp of the tip 4B of the protrusion 4 due to the movement of the plurality of protrusions 4 The hair H as well as the scalp G is washed by the friction with G and the action of the hair washing agent.

As described above, in the embodiment, the plurality of protrusions 4 are substantially symmetrical about the axis A of the substrate 3 on one side surface 3A of the flexible substrate 3 of the brush portion 2, and the as the axis D of the projections 4 is orthogonal to the one side surface 3A of the substrate 3, formed integrally with the substrate 3, provided an edge 3B of the substrate 3 so as to freely slide in respect to the frame 5 Then, by operating the motor 8 as a drive unit, the reciprocating drive means 7 causes the substrate 3 connected to the reciprocating drive means 7 not only to be flexible and stretchable but also to slide. The plurality of protrusions 4 provided on the substrate 3 are repeatedly opened and closed by repeatedly deforming along the axis A between a curved concave state bent upward and a curved convex state bent downward. Repeatedly grabbing and spreading the scalp G The scalp G can be massaged and the scalp G and hair H can be cleaned, and the flexure of the substrate 3 can be increased not only by the flexibility and stretchability of the substrate 3, but also by the sliding of the edge 3B. Or, it does not depend greatly on the material of the substrate 3. That is, as long as the substrate 3 itself bends, the edge 3B of the substrate 3 slides with respect to the frame body 5 even if the substrate 3 itself hardly expands or contracts. As a property required for the material to be stretched, stretchability is not so important, and conditions for material selection are reduced, so the range of materials constituting the substrate 3 can be expanded.

In the above embodiment, since the sliding slot 13 relative to protrusion 14 is slidably disposed between the inner end 13A and an outer end 13B, large uniformly curved deformation of the substrate 3 The scalp G can be uniformly massaged and the scalp G and the hair H can be washed well.

  Moreover, in the said Example, since the base end 4A of the said protrusion 4 is formed thicker than the front-end | tip 4B, it is not dependent on the bending of the said board | substrate 3, but the axis line of the protrusion 4 with respect to the one side 3A of the said board | substrate 3 By maintaining the state where D is orthogonal, the plurality of protrusions 4 can be repeatedly opened and closed even when the brush portion 2 is operated by pressing the tip 4B of the protrusion 4 against the scalp G. And scalp G and hair H can be cleaned.

  Further, since the tip 4B of the protrusion 4 is formed to be narrower than the base end 4A, the tip 4B of the protrusion 4 bends when pressed against the scalp G. And hair H can be washed.

  Furthermore, by configuring the reciprocating drive means 7 with a motor 8, a crank mechanism 9, and a connecting rod 10, complicated movements of the plurality of protrusions 4 provided on the brush portion 2 can be easily realized. .

  Next, another embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the same part as each said Example, and the detailed description is abbreviate | omitted.

7 to 11 show the second embodiment. Reference numeral 22 denotes a brush portion. The brush portion 22 includes a substrate 23 and a plurality of protrusions 4 that are integrally provided so as to protrude toward the one side surface 23A of the substrate 23. Incidentally, the substrate 23 is a thin plate plane having a rectangular flexible and slightly elastic, sliding with respect to the frame 25 in which a pair of edges 23B facing is disposed outside of the base plate 23 Provided to be free. On the other hand, a pair of edges 23D in a direction orthogonal to the edges 23B are free ends. The protrusion 4 is provided so as to be plane-symmetric with respect to a virtual plane (not shown) passing through the central axis A of the substrate 23 and parallel to the edge 23B of the substrate 23.

The edge 23B of the substrate 23 is arranged such that one side surface 23A is along the other side surface of the frame 25, and one side surface 23A of the edge 23B is a sliding portion. A stopper receiving portion 26 is provided on the end side of the edge 23B, and a stopper 27 with which the stopper receiving portion 26 can contact is provided inside the stopper receiving portion 26, that is, on the axis A side. The stopper 27 is arranged slightly above the edge 23B side of the substrate 23 so as to be substantially along the longitudinal direction of the edge 23B. In the embodiment, it is provided in a gate shape so as to sandwich the edge 23B side on the other side of the frame 25. That is, the stopper 27 is paired with the other side surface 23C of the substrate 23 in parallel with the other side surface 23C of the substrate 23 at a distance of the thickness of the substrate 23 (projection length h) with respect to the other side surface of the frame 25. The direction between the edges 23B. On the other hand, the stopper receiving portion 26 is provided integrally or integrally with the substrate 23 inserted between the stopper 27 and the frame body 25 and has an interval L slightly outside the stopper 27. but, this distance L is, the range of the edge 23B can slide. The height H of the stopper receiving portion 26 from the other side surface of the frame body 25 is formed larger than the distance h between the stopper 27 and the other side surface of the frame body 25 (h <H). Therefore, when the edge 23B moves inward, the stopper receiving portion 26 comes into contact with the stopper 27, so that the movement of the edge 23B is suppressed.

  Next, the effect | action is demonstrated about the said structure. When washing the hair, the user first holds the brush device 1, presses the tip 4B of the protrusion 4 of the brush portion 2 against the scalp G, closes the switch 12, and the motor 8 is activated to drive the motor shaft 8A. , The crank mechanism 9 is rotated, the rotational motion of the motor shaft 8A is converted into a reciprocating motion, and the substrate 23 is bent upward as its center reciprocates along the axis A. The deformation with an amplitude of 2F is repeated between the curved concave state and the curved convex state bent downward.

Then, as shown in FIG. 10, when the eccentric shaft 9A of the crank mechanism 9 is above the motor shaft 8A, the substrate 23 itself is bent and the substrate 23 itself is bent by being pulled up by the connecting rod 10. by is lifted, the edges 23B side of the substrate 23 is sliding with respect to the frame 25. By this sliding, the respective stopper receiving portions 26 are drawn inward, so that the stopper receiving portions 26 on the edge 23B move so as to approach the stopper 27. When the stopper receiving portion 26 comes into contact with the stopper 27, the sliding of the edge 23B stops. As a result, the substrate 23 is in a curved concave state bent upward with the center at the top. Of the protrusions 4 formed so as to project integrally with the substrate 23 so as to be orthogonal to the one side surface 23A of the substrate 23, at least the base end 4A is accompanied by the bending of the one side surface 23A of the substrate 23. Thus, by moving integrally while maintaining an orthogonal state with the one side surface 23A, the tips 4B of the plurality of projections 4 are closed, that is, the axes D at least at the base ends 4A of the plurality of projections 4 are inward. It will move in the direction. Then, the motor 8 rotates in this way and the substrate 23 of the brush portion 22 bends upward, so that the protrusion 4 moves inward while in contact with the scalp G. At the same time that the scalp G is massaged by the tip 4B of the protrusion 4, not only the scalp G but also the hair H is washed by a hair wash or the like.

Thereafter, when the eccentric shaft 9A of the crank mechanism 9 is rotated downward from the top dead center, the substrate 23 is pushed by the connecting rod 10 to be gradually deformed, and as shown in FIG. It becomes the curved convex state bent downward. In this process, together with the substrate 23 itself is bent at the be pushed by the connecting rod 10, by which the substrate 23 itself is pressed, the edge 23B side of the substrate 23 is sliding with respect to the frame 25. Since the substrate 23 is deformed from the state of FIG. 10 to the state of FIG. 11 through the state of FIG. 8, the substrate 23 has a pair of stopper receiving portions 26 with respect to the frame 25. After the stopper receiving portion 26 slides away from the stopper 27 by being pushed outward (FIG. 10 → FIG. 8), each of the stopper receiving portions 26 is pulled inward again, so that the edge 23B The stopper receiving portion 26 slides so as to approach the stopper 27 (FIG. 8 → FIG. 11). When the stopper receiving portion 26 comes into contact with the stopper 27, the sliding of the edge 23B stops. As a result, the substrate 23 is in a curved convex state bent downward with the center at the bottom. Then, at least the base end 4A of the projections 4 moves integrally with the one side surface 3A substantially in an orthogonal state with the bending of the one side surface 3A of the substrate 3, thereby the plurality of projections. The tip ends 4B of the four projections 4 are opened, that is, the axes D at least at the base ends 4A of the plurality of projections 4 are moved outward. Then, the motor 8 rotates in this way and the substrate 23 of the brush portion 2 bends downward, so that the protrusion 4 moves outward in a state of being in contact with the scalp G. The scalp G is massaged so as to be spread by the tip 4B of the protrusion 4, and at the same time, not only the scalp G but also the hair H is washed by a hair washing agent or the like.

  In this way, the rotational force of the motor 8 is converted into a reciprocating motion by the crank mechanism 9 and the connecting rod 10, and the substrate 23 of the brush portion 22 is placed in a state where the protrusion 4 is kept in contact with the scalp G. In addition to the flexibility and stretchability of 23, the plurality of projections 4 provided integrally with the substrate 23 are repeatedly bent by repeatedly sliding the edge 23B of the substrate 23 in and out of the frame 25. By opening and closing, the scalp G is stimulated to be gripped and spread by the plurality of protrusions 4 and massaged, and the scalp of the tip 4B of the protrusion 4 due to the movement of the plurality of protrusions 4 The hair H as well as the scalp G is washed by the friction with G and the action of the hair washing agent.

As described above, in the above-described embodiment, the plurality of protrusions 4 are substantially symmetrical with respect to the axis A of the substrate 23 on the one side surface 23A of the flexible substrate 23 of the brush portion 2, and The projection 4 is formed integrally with the substrate 23 so that the axis D of the projection 4 is orthogonal to the one side surface 23A of the substrate 23, and the edge 23B of the substrate 23 is contacted with the stopper 27 until the stopper receiving portion 26 abuts the stopper 27. in the range of, provided so as to be freely sliding with respect to the frame 25, by operating the motor 8 as a driving unit, the reciprocating drive means 7, the substrate which is connected to the reciprocating drive means 7 23 is repeatedly deformed along the axis A between not only the flexibility and stretchability of the substrate 23 but also the curved concave state bent upward by the sliding and the curved convex state bent downward. Thus, the plurality of protrusions 4 provided on the substrate 23 are repeatedly opened and closed. Therefore, it is possible to repeat the operation of grabbing and spreading the scalp G to massage the scalp G and clean the scalp G and the hair H, and to flex the substrate 23 with the flexibility of the substrate 23 and In addition to the stretchability, the degree of flexure can be increased by sliding the edge 23B, or it does not depend greatly on the material of the substrate 23.

  Further, since the stopper receiving portion 26 is drawn inward and slid until it comes into contact with the stopper 27 so that the substrate 23 is in a curved state, the sliding length of the stopper receiving portion 26 and the stopper is reduced. It can be accurately set by the interval L with 27.

  12 to 17 show the third embodiment. In Example 3, an example using the massage device 1A is shown.
