Thereby, the position where the hook receiving portion 4B is provided is formed in the maximum amplitude portion of the substrate 4. And the amplitude thereof is twice (2F) from the central axis of the crank 15 to the eccentric distance F of the eccentric shaft 15A. Further, the hook center receiving portion 4B and the connecting relay member 17 form a virtual central axis X in the vertical direction. Further, a battery 18 for supplying electric power to the motor 13 is provided inside the electric brush device main body 2, and a switch 19 for operating the motor 13 is provided on the upper surface side surface of the electric brush device main body 2.

Further, the substrate 4 is provided with a first communication portion 21 and a second communication portion 22 that communicate with a small through-hole shape inside and outside the region surrounded by the frame 6, the seat portion 6E, and the brush portion 3. Moreover, in the foregoing field, the communication portion is provided 21. The communication portion 22 is connected to the shampoo container 26 that is activated in response to the deflection of the substrate 4. Further, with the central axis X as a center, a plurality of small projections 27 are arranged in a ring shape, and an annular wall 28 is provided to connect the small projections 27 to each other, and the aforementioned ring from the surface 4S of the substrate 4 is further provided. The protruding dimension of the wall 28 is smaller than the protruding dimension of the aforementioned small projection 27. Further, the substrate 4 is divided into inner and outer portions by the small protrusions 27 and the annular wall 28, and the second communication portion 22 is formed in a region surrounded by the small protrusions 27 and the annular wall 28, and On the one hand, the first communication portion 21 is formed on the outer side region of the small protrusion 27 and the annular wall 28.

The storage body 26 is repeatedly compressed and restored in response to the deflection of the substrate 4, whereby the shampoo is sucked or discharged from the communication portions 21 and the communication portion 22. Further, in the embodiment, the storage body 26 is formed by using a synthetic sponge or sponge (natural sponge) composed of a continuous-bubble foamed polyurethane or a foamed rubber which is an elastomer, and the like. As shown in FIG. 2, when the substrate 4 is bent downward, the storage body 26 is substantially in an uncompressed state or a slightly compressed state, and is interposed between the frame 6, the seat portion 6E, and the substrate. 4 on the top. That is, when the substrate 4 is bent downward in a curved state, the upper surface 26A of the storage body 26 is joined or close to the lower surface 6B of the frame body 6 and the seat portion 6E, and the lower surface 26B of the storage body 26 is coupled to The upper surface of the substrate 4 is joined or brought close to each other. Further, the outer circumference 26C of the storage body 26 is joined or brought close to the edge portion 4A of the substrate 4. On the other hand, a through hole 26D is formed along the center axis X in the center portion of the storage body 26, and the hook receiving portion 4B and the hook portion 17A are connected via the through hole 26D.

Next, the effect is explained with respect to the aforementioned configuration. When the scalp S is washed or massaged, first, the user preliminarily causes the storage body 26 to contain an appropriate amount of water, and the water is immersed in the water by the electric brush device 1 to pass through the communication portions 21 and the communication portion. 22 is absorbed by the storage body 26 described above. Further, the surface 4S of the substrate 4 is formed to face upward, and an appropriate amount of shampoo is placed in a region surrounded by the small protrusion 27 and the annular wall 28. At this time, the small protrusion 27 and the ring are placed thereon. The aforementioned shampoo in the region surrounded by the wall 28 does not flow out toward the outer region of the small projection 27 and the annular wall 28 as long as it is not excessively placed. Further, a small amount of shampoo penetrates into the side of the storage body 26 from the second communication portion 22.

Next, when the switch 19 is operated, electric power is supplied from the battery 18, and the motor 13 is actuated to rotate the motor shaft 13A. With the rotation, the crank 15 connected to the motor shaft 13A through the reduction gear mechanism 14 is rotated, and the motor shaft 13A is rotated by the crank 15 and the yoke 16 coupled to the eccentric shaft 15A of the crank 15. The rotational motion is converted into a reciprocating motion, and the aforementioned connection relay member 17 that has been attached to the lower end of the rod 16A integrally formed with the yoke 16 is reciprocated upward and downward. Further, in order to form the maximum receiving portion of the hook portion 17B connected to the hook portion 17A of the connection relay member 17, that is, the center of the substrate 4 constitutes the maximum amplitude, the substrate 4 is the same as the prior art. The curved convex state of the downward deflection and the curved concave state of the upward deflection are reversely deformed, and the amplitude in the maximum amplitude is formed from the central axis of the crank 15 to the eccentric distance F of the eccentric shaft 15A. 2 times (2F).

Accordingly, the substrate 4 is bent and convexly directed downward and upward. The space between the curved portion and the concave portion of the square is reversely deformed, whereby the space between the lower surface 6B of the substrate 4 and the frame 6 and the seat portion 6E is reversely compressed and restored. As a result, the storage body 26 is adapted to the substrate 4 Flexing and moving to reverse compression and recovery. Further, when the storage body 26 is restored from the compressed state, the space between the lower surface 6B of the substrate 4 and the frame 6 and the seat portion 6E is decompressed, whereby the annular small projections 27 and the ring shape are placed thereon. The shampoo in the inner region of the wall 28 is sucked from the second communication portion 22 and flows into the space, and is accommodated in the storage body 26. On the other hand, when the storage body 26 is compressed, the shampoo that has been stored in the storage body 26 is ejected from the second communication portion 22. Further, when the shampoo is extruded through the second communication portion 22, it is foamed by mixing with air. In addition, by shuffling the deformation of the storage body 26, the shampoo is gradually diffused from the center of the storage body 26 toward the outer peripheral side, whereby the configuration is also pressed from the first communication portion 21 The aforementioned shampoo that has been foamed. According to this, the storage body 26 is repeatedly compressed and restored in response to the deformation of the substrate 4 which is reversed between the curved convex state and the curved concave state, whereby the small projection 27 and the annular wall 28 are placed inside. The shampoo in the region is foamed and supplied from the entire brush portion 3 to the outside. Further, the shampoo is finely foamed when passing through the communicating portion 21 and the communicating portion 22, and the smaller the pore diameter of the communicating portion 21 and the communicating portion 22, the finer the shampoo is.

According to this, in the state in which the shampoo has been foamed, the user holds the electric brush device body 2 and presses the front end portion of the protrusion 5 against the scalp S to hold it by hand, thereby mainly The protrusion 5 will repeatedly tilt the center axis X as a center toward the inner side or rise thereafter. Thereby, the scalp S can be rubbed, washed, or stimulated to be massaged.

In this case, the plurality of the protrusions 5 and the scalp S must be uniformly abutted by the brush portion 3 being aligned with the scalp S. However, since the user cannot correctly recognize the state, the electric brush has been held. In the state of the apparatus main body 2, the brush portion 3 is configured to be substantially opposite to the scalp S. However, the brush portion 3 is not facing the scalp S (the central axis X is inclined with respect to the scalp S). In the state, as shown by the arrow mark Z in Fig. 2, the brush portion 3 is swung around the swing center axis Y of the shaft 8 with respect to the electric brush device main body 2, whereby the brush portion 3 is used. It is possible to automatically abut against the scalp S, and therefore, the scalp S can be uniformly washed or massaged by the plurality of protrusions 5 described above.

In addition, since the human head is not actually a simple shape, if only the brush portion 3 and the head surface, that is, the scalp S are facing, the scalp S may not be well washed or massaged by the protrusions 5, However, as described above, since the frame body 6 is configured to be elastically deformable, the base portion 4 of the brush portion 3 can be scratched in response to the shape of the scalp S by pressing the brush portion 3 against the scalp S. The frame 6 that fixes the brush portion 3 is also deflected due to the deflection of the base portion 4. Further, the frame 6 may be formed to be curved at both ends (Fig. 4(b)) or to be twisted (Fig. 4(c)). According to this, since the base portion 4 of the brush portion 3 can be deformed in accordance with the shape of the scalp S, the scalp S can be washed or massaged more satisfactorily by the protrusions 5.

As described above, the foregoing embodiment has the electric brush device body 2 and the brush portion 3 that is actuated by the electric brush device body 2, and the brush portion 3 is made of a substrate made of a flexible material. 4 and disposed on the surface of the substrate 4 The 4S protruding plurality of protrusions 5 are formed, and the electric brush device main body 2 is provided with a frame body 6 for holding the peripheral edge of the substrate 4 detachably, and the frame body 6 is provided to be opposite to the electric brush device. The main body 2 is swung by the support mechanism 7, whereby even if the projection 5 is brought into contact with the scalp S in a state where the brush portion 3 is not facing the scalp S, the brush portion 3 is opposed to the abutment state of the projection 5 Since the electric brush device main body 2 is swung, the brush portion 3 and the scalp S can be automatically corrected, and the plurality of protrusions 5 of the brush portion 3 can be uniformly contacted with the scalp S to wash or massage the scalp S. .

Further, the frame body 6 is connected by the support mechanism 7 constituted by the shaft 8 and the bearing portion 8A, and the pivot center axis Y of the shaft 8 is orthogonal to the central axis X of the substrate 4, whereby The aforementioned shaft 8 can be used as the swing center axis Y so that the brush portion 3 which has been held by the frame body 6 is automatically opposed to the scalp S.

Further, since the frame body 6 is configured to be elastically deformable, the frame body 6 or the brush portion 3 attached to the frame body 6 is elastically deformed in accordance with the shape of the scalp S, so that the brush portion can be made The protrusion 5 of 3 is in good contact with the scalp S.

[Embodiment 2]

Fig. 6 shows a second embodiment, and the same portions as those of the first embodiment are denoted by the same reference numerals, and the detailed description thereof will be omitted. In the support mechanism 7' of the second embodiment, a pair of pillar-shaped hanging members 7'A are provided from the bottom surface portion 2B of the electric brush device body 2 toward the lower surface, respectively, and below the hanging member 7'A, The bearing portion 6'F that has been formed on the upper surface of the frame 6 is rotatably coupled through the shaft 8', and the pivot center axis (not shown) of the shaft 8' is coupled to the central shaft. Lines (not shown) are orthogonal.

Therefore, the brush portion 3 swings the shaft 8' as the swing center with respect to the electric brush device main body 2 in response to the abutment state of the projections 5, so that the brush portion 3 and the scalp S can be automatically corrected. .
