Problems solved by technology

As a result, according to the shape of the base plate 103 of the above-mentioned treatment part 102, even if the above-mentioned protrusions 104, 105 are pressed onto the scalp S, the base plate 103 and the frame body 106 supporting the protrusions cannot be arranged along the scalp S, and the protrusions 104, 105, 105 cannot press the scalp S evenly, so the electric brush device is in an unstable state on the scalp S, and one may have to use the electric brush device in this unstable state
In addition, there is also a defect, that is, in the aforementioned electric brush device, the bending of the substrate 103 is performed in the form of concentric circles with the center of the substrate 103 having the largest amplitude as the center. Therefore, when the plane of the substrate 103 is When the shape is non-circular, there will be a small curved part in the above-mentioned substrate 103, and the protrusions arranged on the small curved part hardly work, resulting in poor cleaning and massage effects

Embodiment 1

[0029] Figure 1 to Figure 5 The case of Example 1 is shown. In this example, with image 3 The static state shown is the reference to specify the up and down directions. 1 is the electric brush device of this invention. This electric brush device 1 is constituted by a device body 2 as a drive unit, and a brush unit 3 that is held on the lower portion of the device body 2 and can be freely attached and detached.

[0030] The brush portion 3 is composed of a base plate 4 and a plurality of protrusions 5 provided integrally therewith, and the protrusions 5 protrude downward in a direction intersecting the bottom surface 4S of the base plate 4 . In addition, when the above-mentioned substrate 4 is in a natural state not mounted on the above-mentioned device body 2, the surface 4S on which the above-mentioned protrusion 5 protrudes has a convex shape. Furthermore, the above-mentioned substrate 4 is elliptical in plan view, and is formed of a flexible and elastic elastic body. ...

Embodiment 2

[0058] Figures 6 to 7 Embodiment 2 is shown, and the same parts as those of the above-mentioned Embodiment 1 are designated by the same symbols, and detailed descriptions thereof are omitted. In the support 7' of the second embodiment, a bearing 8A is provided on the bottom plate 9 side, and a shaft 8 inserted into the bearing 8A is provided on the frame body 6 side. In addition, in the sealing member 20', the upper part 20A' is fixed to the above-mentioned bottom plate 9, and the lower part 20B' is slidably and air-tightly pressed against the inner part 6A of the above-mentioned frame body 6 in a line contact state.

[0059] Also in this modified example, the same effects as those in Example 1 are obtained.

Abstract

There is provided an electrically driven brush device allowing a plurality of protrusions to be pressed evenly against an entire portion of a scalp. The electrically driven brush device comprises a device main body 2 serving as a drive section and a brush member 3 operated by the device main body 2. The brush member 3 comprises a body plate 4 made of a flexible material and a plurality of protrusions 5 protruding from a surface 4S of the body plate 4. The device main body 2 is provided with a frame 6 holding an edge 4A of the body plate 4. The frame 6 is provided so as to be curved so that an outer section 6B thereof is formed further away from the device main body 2 than an inner section 6A thereof. As a result, even if the body plate 4 of the brush member 3 and the frame 6 holding the body plate 4 are formed in noncircular shapes, the uniformity of the pressing force of the protrusions 5 against the scalp S can be improved.

Description

technical field [0001] The present invention relates to an electric brush device, and in particular, relates to an electric brush device which can be used for washing or massaging the scalp. Background technique [0002] This type of electric brush device commonly known by people is a massage device as described below, which has a driving part and a treatment part (equivalent to the brush part in the present invention) that works by means of the driving part. The driving part is provided with a frame for holding the edge of the substrate of the treatment part so as to fix the relative position between the treatment part and the driving part, and the treatment part can be freely attached and detached. At the same time, it is connected to the center of the above-mentioned substrate, and a reciprocating drive mechanism is provided in a direction crossing the surface of the substrate. The treatment part is composed of a base plate made of elastic material and a plurality of pro...
