Problems solved by technology

Therefore, it is difficult to efficiently move the electrolytic medicinal ingredients in the toothpaste by the conduction of electricity from the conductive bristles.
[0007] In addition, when it is desired to bring the conductive bristles into contact with the gums, etc., since the insulating bristles around the conductive bristles contact the gums first, it is difficult to obtain the massage effect caused by the conduction of electricity from the conductive bristles to the gums, etc.

no. 1 Embodiment approach

[0025] refer to figure 1 ˜ FIG. 4 illustrate the electric toothbrush 1 according to the first embodiment of the present invention.

[0026] Such as figure 1 As shown, the electric toothbrush 1 includes: a holding main body 20 capable of being held by a user; and a brush body 10 detachably attached to the front end of the holding main body 20 . The electric toothbrush 1 is configured to brush the teeth by vibrating the brush body 10 by the vibration driver 22 incorporated in the grip main body 20 .

[0027] The grip main body portion 20 is formed in a substantially cylindrical shape in consideration of the user's grip and the like. The grip body 20 includes: a grip electrode 21 configured to contact the user's hand when the user grips the outer surface of the grip body 20; a switch 26 operated by the user; and an LED 27 for displaying the operating state. A vibration driver 22 , a battery 24 for supplying power to a circuit unit 25 , and a circuit unit 25 for controlling pow...

no. 2 Embodiment approach

[0052] An electric toothbrush 1 according to a second embodiment of the present invention will be described with reference to FIGS. 5 and 6 .

[0053] In the electric toothbrush 1 according to the second embodiment, the structure of the head part 11 of the electric toothbrush according to the first embodiment is changed. This point of change will be described in detail below. In addition, since other parts have the same configuration as that of the first embodiment, the same reference numerals are assigned to the common configuration, and description thereof will be omitted.

[0054] As shown in FIG.5(a), the brush head part 11 is equipped with the several conductive bristle bundle 50 and the several insulating bristle bundle 60 which remove plaque etc.. As shown in FIG. The base ends of the respective conductive bristle bundles 50 and the respective insulating bristle bundles 60 are implanted on the conductive member 14 via the surface of the brush head 11 , that is, the bri...

no. 3 Embodiment approach

[0066] Referring to Figure 7 and Figure 8 , and the electric toothbrush 1 according to the third embodiment of the present invention will be described.

[0067] In the electric toothbrush 1 according to the third embodiment, the structure of the head part 11 of the electric toothbrush according to the second embodiment is changed. This point of change will be described in detail below. In addition, since other parts employ the same configuration as that of the second embodiment, the same reference numerals are assigned to the common configuration, and description thereof will be omitted.

[0068] As shown in FIG. 7( a ), the height h from the flocking surface 13 to the front end of the insulating bristle bundle 60 is greater than the height from the flocking surface 13 to the front end of the conductive bristle bundle 50 . This height difference forms the storage portion 34 at the front end of the conductive bristle bundle 50 .

[0069] In the brush head 11 , insulating br...

Abstract

A brush body and toothbrush that allows for current to easily flow from conductive bristles to oral tissues or enhance ionization of electrolytic medicinal components. The brush body (10) includes a mixed bristle bundle (70) arranged on an anchoring surface (13) and including a plurality of conductive bristles (30) and a plurality of insulative bristles (40). A reference plane is set on the anchoring surface (13). The conductive bristles (30) have a height from the reference plane, and the insulative bristles (40) have a height from the reference plane that differs from the height of the conductive bristles (30).

Description

technical field [0001] The invention relates to a brush body and a toothbrush comprising the brush body. Conductive bristles with conductivity and insulating bristles with insulation are arranged on the bristle-planted surface of the brush body. Background technique [0002] As an example of the said toothbrush, the toothbrush described in Unexamined-Japanese-Patent No. 2006-223369 is known. [0003] In the toothbrush disclosed in Japanese Unexamined Patent Publication No. 2006-223369, a bundle of conductive bristles having conductivity is provided in the center of the brush body. [0004] However, if the toothpaste used for brushing teeth contains an electrolytic medicinal ingredient having an oral bactericidal effect, the medicinal ingredient can enter the tooth surface or gums by the action of an electric current, so the oral bactericidal effect is improved. The periodontal disease prevention effect can be expected by sterilizing the inside of the oral cavity, especially...
