Description

  The present invention relates to an electric brush device, and more particularly to an electric brush device that can be used for scalp washing, massage, and the like.

  Conventionally, this type of electric brush device has a drive unit and a treatment unit (corresponding to the brush unit of the present invention) operated by this drive unit, and the drive unit has a peripheral edge of the substrate of the treatment unit. And a reciprocating driving means for bending the substrate in a direction intersecting the surface of the substrate by connecting to the center of the substrate. There is known a massage apparatus in which the treatment portion is composed of the substrate made of a flexible material and a plurality of protrusions provided to protrude from the substrate. And in this massage device, the user holds the drive unit, presses the tip of the projection against the scalp and holds it by hand, and flexes the substrate of the treatment unit by the reciprocating drive means, As the plurality of protrusions provided on the substrate are repeatedly tilted and raised, the scalp is squeezed, rubbed and struck by the mutual opening and closing protrusions. Can be massaged complexly. As shown in FIG. 7 and FIG. 8, the treatment unit 102 driven by the drive unit 101 is deformed between a curved convex state where the substrate 103 is bent downward and a curved concave state where the substrate 103 is bent upward. When repeating, a plurality of types of protrusions 104, 105, 106, 107 arranged from the center side to the peripheral side move along with the bending of the substrate 103, so that the protrusions 104, 105, The scalp S can be massaged to be performed with the fingertips 106 and 107 (for example, Patent Documents 1 and 2).

  In the prior art, in order to apply a plurality of protrusions 104, 105, 106, and 107 to the scalp S almost evenly, the user drives the treatment unit 102 so as to face the scalp S. The part 101 needs to be held.

  However, the scalp is facing upward at the top of the head and sideways at the side of the head, and in order to hold the massage device main body so that the treatment part faces the scalp, the position of the treatment part depends on the position of the scalp Although it is necessary to change the direction, there is a possibility that the treatment part cannot be directly opposed to the scalp unless the wrist is twisted or the drive part is re-pick up. Further, since the human head is not a simple shape, there is a concern that the conventional massage device cannot satisfactorily massage or clean the surface of the head, that is, the scalp.

  The problem to be solved by the present invention is to connect a brush unit to a driving device, press the projection of the brush unit against the scalp, and wash or massage the scalp so that it is performed with a fingertip. It is intended to allow the protrusions of the brush part to be directly opposed to the scalp at any location.

Both are detachably connected over the entire circumference. In addition, 4H in the figure is a knob provided integrally with one end of the substrate 4 in the major axis direction.

  The frame body 6 is made of an elastically deformable synthetic resin and is formed in an elliptical ring shape in plan view. The frame body 6 is provided slightly below the gap L from the bottom surface portion 2B of the electric brush device main body 2. The frame body 6 is provided so as to be swingable with respect to the electric brush device main body 2. An inclined surface 6 </ b> A is formed on the upper surface of the frame body 6. In the natural state, the inclined surface 6A is formed so as to gradually become lower from the inner side (centerline axis X side described later) toward the outer side. On the other hand, the lower surface 6B of the frame 6 is formed horizontally in the natural state. An edge 4 </ b> A of the substrate 4 of the brush unit 3 that is folded back in an inverted U shape or an inverted U shape is fitted to the outer edge 6 </ b> C of the frame body 6. At this time, since the inclined surface 6 </ b> A is formed on the frame body 6, the outer edge 6 </ b> C is thinned, so that the edge 4 </ b> A can be easily fitted to the outer edge 6 </ b> C of the frame body 6. A sheet 6E made of a material having flexibility and elasticity such as elastomer is stretched in the window hole 6D formed inside the frame body 6. A connection relay member 17 and a hook 17A, which will be described later, are provided at the center of the sheet 6E. Further, a pair of column-like suspension members 6F are provided symmetrically on the minor axis of the elliptical frame 6. The suspension member 6F is formed longer than the dimension of the gap L.

  The frame body 6 is swingably supported by support means 7 with respect to the electric brush device body 2. The support means 7 includes a shaft 8 and a bearing portion 8A. The bearing 8A is provided in a pair of recesses 2C formed in the bottom surface 2B of the electric brush device main body 2, and the upper portions of the suspension members 6F are inserted into these recesses 2C, respectively. The The suspension member 6F is pivotally connected to the bearing portion 8A by the shaft 8. Further, the rotation center axis Y of the shaft 8 is orthogonal to a center line axis X described later.

  The electric brush device main body 2 includes a case main body 2A having an opening on the bottom side and a size that can be grasped with one hand, and the bottom surface portion 2B that closes the open bottom side of the case main body 2A. Has been. The bottom surface portion 2 </ b> B has a bottom plate 9 and a cover body 11. The bottom plate 9 is formed in an elliptical shape in plan view, and its outer periphery is fixed to the bottom edge of the case main body 2A. A window hole 10 is formed, and the cover body 11 that covers the window hole 10 and can be expanded and contracted is provided. The cover 11 is provided so as to seal the window hole 10 in a watertight manner by a bellows-like film made of a flexible material such as rubber, synthetic rubber, or elastomer. A reciprocating drive means 12 for reciprocating the central portion of the substrate 4 in the vertical direction is provided inside the electric brush device body 2. The reciprocating drive means 12 includes a motor 13 as a drive source, a crank 15 connected to a motor shaft 13A of the motor 13 via a reduction gear mechanism 14, and a yoke 16 coupled to an eccentric shaft 15A of the crank 15. The rod 16A formed integrally with the yoke 16 is provided. Thus, in the present embodiment, a so-called Scotch-yoke mechanism is employed, but a crank mechanism may be employed. Note that a connection relay member 17 is integrally attached to substantially the center of the cover body 11. The connection relay member 17 sandwiches and fixes the cover 11 between the upper surface side thereof and the lower end of the rod 16A, and a hook 17A is provided on the lower surface side thereof. A hook receiving portion 4B provided on the central upper surface is detachably connected. Therefore, the connection relay member 17 is reciprocated in the vertical direction by converting the rotational motion of the motor 13 into reciprocal motion between the crank 15 and the yoke 16. Thereby, the position where the hook receiving portion 4B is provided becomes the maximum amplitude portion in the substrate 4, and the amplitude is twice the eccentric distance F from the central axis of the crank 15 to the eccentric shaft 15A (2F). It becomes. A virtual center axis X is formed in the vertical direction through the hook receiving portion 4B and the connection relay member 17. In addition, a battery 18 for supplying electric power to the motor 13 is provided inside the electric brush device main body 2, and the motor 13 is provided on the upper surface of the electric brush device main body 2. A switch 19 is provided for operating.

  Furthermore, the substrate 4 is provided with a first through-hole communication portion 21 and a second communication portion 22 each having a small through hole communicating with the inside and outside of a region surrounded by the frame body 6, the sheet 6 </ b> E, and the brush portion 3. In the region, a shampoo container 26 that communicates with the communication portions 21 and 22 and responds to the bending of the substrate 4 is provided. A plurality of small protrusions 27 are arranged in a ring shape around the central axis X, and an annular wall 28 is provided so as to connect the small protrusions 27 to each other. Further, the projecting dimension of the annular wall 28 from the surface 4S of the substrate 4 is smaller than the projecting dimension of the small protrusion 27. The substrate 4 is partitioned inward and outward by the small protrusions 27 and the annular wall 28. The second communication part 22 is formed in an area surrounded by the small protrusions 27 and the annular wall 28. On the other hand, the first continuous portion 21 is formed in a region outside the small protrusion 27 and the annular wall 28.

  The container 26 is adapted to repeatedly compress and restore in response to the bending of the substrate 4, thereby sucking and discharging the shampoo from the communicating portions 21 and 22. The container 26 is formed of a synthetic sponge or sponge (natural sponge) made of an open-cell foamed polyurethane, foamed rubber, or the like, which is an elastic body in the embodiment. As shown in FIG. When the substrate 4 is in a curved convex state bent downward, the container 26 is almost uncompressed or slightly compressed, and is interposed between the frame 6, the sheet 6 </ b> E, and the upper surface of the substrate 4. ing. That is, when the substrate 4 is curved and bent downward, the upper surface 26A of the container 26 is in contact with or close to the lower surface 6B and the sheet 6E of the frame body 6, and the lower surface 26B of the container 26. Is in contact with or close to the upper surface of the substrate 4, and the outer periphery 26 </ b> C of the container 26 is in contact with or close to the edge 4 </ b> A of the substrate 4. On the other hand, a through-hole 26 </ b> D is formed in the central portion of the container 26 along the central axis X. The hook receiving portion 4B and the hook 17A can be connected through the through hole 26D.

  Next, the effect | action is demonstrated about the said structure. When cleaning or massaging the scalp S, the user first puts an appropriate amount of water in the container 26 in advance. In addition, water is absorbed by the container 26 through the communication portions 21 and 22 by immersing the electric brush device 1 in water. Then, an appropriate amount of shampoo is placed on the area surrounded by the small protrusions 27 and the annular wall 28 with the surface 4S of the substrate 4 facing upward. At this time, the shampoo placed on the area surrounded by the small protrusion 27 and the annular wall 28 does not flow out to the area outside the small protrusion 27 and the annular wall 28 unless it is excessively placed. A small amount of shampoo penetrates from the second communicating portion 22 into the container 26 side.

  Next, when the switch 19 is operated, electric power is supplied from the battery 18, whereby the motor 13 is operated and the motor shaft 13 </ b> A is rotated. Along with this rotation, the crank 15 connected to the motor shaft 13A via the reduction gear mechanism 14 rotates, and the motor shaft is coupled by the crank 15 and the yoke 16 coupled to the eccentric shaft 15A of the crank 15. The rotational movement of 13A is converted into a reciprocating movement, and the connection relay member 17 attached to the lower end of the rod 16A formed integrally with the yoke 16 reciprocates up and down. Then, the substrate 4 is the same as in the prior art so that the hook receiving portion 4B connected to the hook 17A provided on the connection relay member 17, that is, the center of the substrate 4 is the maximum amplitude portion. The deformation is repeated between a curved convex state bent downward and a curved concave state bent upward, and the amplitude at the maximum amplitude portion is an eccentric distance F from the central axis of the crank 15 to the eccentric shaft 15A. Double (2F).

  In this way, the substrate 4 is repeatedly deformed between the curved convex state where the substrate 4 is bent downward and the curved concave state where the substrate 4 is bent upward. The space 26 is repeatedly compressed and restored. As a result, the container 26 is repeatedly compressed and restored in response to the bending of the substrate 4. When the container 26 is restored from the compressed state, the space between the substrate 4, the lower surface 6 </ b> B of the frame 6 and the sheet 6 </ b> E is in a reduced pressure state, so that the annular small protrusion 27 and the annular wall 28 are The shampoo placed on the inner area is sucked from the second communication portion 22 and flows into the space, and is accommodated in the accommodating body 26. Conversely, when the container 26 is compressed, the shampoo accommodated in the container 26 is ejected from the second communication portion 22. The shampoo is foamed by being mixed with air when pushed out through the second communication portion 22. Then, the deformation of the container 26 is repeated in this manner, so that the shampoo gradually spreads from the center of the container 26 to the outer peripheral side. The applied shampoo will be pushed out. In this way, the container 26 repeatedly compresses and restores in response to the deformation of the substrate 4 repeated between the curved convex state and the curved concave state, so that the inner area of the small protrusion 27 and the annular wall 28 is obtained. The shampoo placed on is bubbled and supplied to the outside from the entire brush unit 3. The shampoo is finely bubbled when passing through the communication parts 21 and 22. And the said shampoo will be bubbled finely, so that the diameter of the hole of the said communication parts 21 and 22 is small.

  Thus, in a state where the shampoo is foamed, the user holds the electric brush device main body 2 and presses the tip of the protrusion 5 against the scalp S and holds it by hand. As a result, the protrusion 5 mainly rubs the scalp S by being inclined inwardly with respect to the central axis X, or is erected afterwards, and gives a stimulus. You can massage.

  At this time, it is necessary to bring the plurality of protrusions 5 into equal contact with the scalp S by making the brush portion 3 directly face the scalp S. However, since the user cannot accurately recognize this state, In a state where the brush device main body 2 is gripped, the brush portion 3 is roughly opposed to the scalp S. However, in a state where the brush portion 3 does not face the scalp S (the central axis X is inclined with respect to the scalp S), as shown by an arrow Z in FIG. Oscillates around the oscillation center axis Y of the shaft 8 with respect to the electric brush device main body 2 so that the brush portion 3 can automatically come into contact with the scalp S in a state of facing the scalp S. Therefore, the scalp S can be uniformly washed or massaged by the plurality of protrusions 5.

  Since the human head is not actually a simple shape, the scalp S is not necessarily cleaned well or massaged by the protrusions 5 when the brush part 3 is just facing the head surface, that is, the scalp S. It is not always done. However, since the frame 6 is configured to be elastically deformable as described above, the base portion 4 of the brush portion 3 bends according to the shape of the scalp S by pressing the brush portion 3 against the scalp S. In response to the bending of the base portion 4, the frame body 6 fixing the brush portion 3 is also bent. The frame body 6 can be deformed so that both ends thereof are curved (FIG. 4B) or deformed so as to be twisted (FIG. 4C). Thus, since the base part 4 of the brush part 3 can be deformed according to the shape of the scalp S, the scalp S can be cleaned and massaged better by the protrusions 5.

  As mentioned above, in the said Example, it has the electric brush apparatus main body 2 and the brush part 3 which operate | moves by this electric brush apparatus main body 2, and this brush part 3 consists of a material which has flexibility. A substrate 4 and a plurality of projections 5 provided so as to protrude from the surface 4S of the substrate 4 are provided, and a frame body 6 is provided on the electric brush device body 2 for detachably holding the periphery of the substrate 4. By providing the frame body 6 so as to be swingable with respect to the electric brush device main body 2 via the support means 7, the protrusion 5 comes into contact with the brush portion 3 not facing the scalp S. Even so, since the brush portion 3 swings with respect to the electric brush device main body 2 according to the contact state of the protrusion 5, it can be automatically corrected so that the brush portion 3 faces the scalp S, Uniformity of the plurality of protrusions 5 of the brush part 3 on the scalp S By abutment, it can be favorably cleaned or massaging the scalp S.

  Further, the frame body 6 is connected by the support means 7 including the shaft 8 and the bearing portion 8A, and the swing center axis Y of the shaft 8 is orthogonal to the center axis X of the substrate 4. By doing so, the brush portion 3 held by the frame body 6 can be automatically faced to the scalp S with the shaft 8 as the oscillation center axis Y.

  Furthermore, since the frame 6 is configured to be elastically deformable, the brush 6 attached to the frame 6 and eventually the frame 6 is elastically deformed according to the shape of the scalp S. 3 can be satisfactorily brought into contact with the scalp S.

  FIG. 6 shows a second embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In the support means 7 'of the second embodiment, a pair of support-like suspension members 7'A are provided downward from the bottom surface portion 2B of the electric brush device body 2, and the suspension members 7'A are provided below the suspension members 7'A. , A bearing portion 6'F formed on the upper surface of the frame body 6 via a shaft 8 'is rotatably connected, and a swing center axis (not shown) of the shaft 8' is a center axis ( (Not shown).

  Accordingly, the brush portion 3 swings with respect to the electric brush device main body 2 about the shaft 8 'as a swing center in accordance with the contact state of the protrusion 5, so that the brush portion 3 faces the scalp S. Can be corrected automatically.

  As described above, the electric brush device according to the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the invention. For example, in the above-described embodiment, the electric brush device that can be used for cleaning and massaging the scalp and the like has been described. However, the present invention may be applied to a massaging device that can be used for any part of the human body.
