Description

The present invention relates to an electric toothbrush, and more particularly to a toothbrush capable of brushing the inside and outside of the gum with an appropriate pressure and reliably removing plaque in a periodontal pocket.

It has become known that oral hygiene is one of the causes of various diseases, and it has become common to brush teeth not only at home but also at work and travel destinations. Toothbrushes are required to be able to perform fine cleaning over the entire tooth, and electric toothbrushes are attracting attention.

For example, we have proposed an electric toothbrush that has a drive source such as a motor built into the body, and a toothbrush handle that is detachably attached to the tip of the body so that the toothbrush is placed on the teeth and rotated by the drive source to vibrate. (Patent Document 1, Patent Document 2).

Japanese Unexamined Patent Publication No. 2005-296515 Special Table 2003-531672

However, in the electric toothbrushes described in Patent Documents 1 and 2, the outer gums and periodontal pockets and the inner gums and periodontal pockets must be cleaned separately, and the toothbrush is finely moved with an appropriate force for brushing. It was necessary and annoying, and in many cases, it was brushed by moving it with a strong force while pushing it, which could damage the gums.

In view of these problems, the present invention provides an electric toothbrush that can clean the outer gums and periodontal pockets and the inner gums and periodontal pockets at the same time, and can easily move the toothbrush finely for brushing. That is the issue.

Therefore, the electric toothbrush according to the present invention is an electric toothbrush that can simultaneously remove plaques in the periodontal pockets on both the inner and outer sides and can brush the toothbrushes on both the inner and outer sides at the same time by moving the brush finely. It is composed of a body that can be grasped by a person with one hand and a brush at the tip of the handle. The handle is detachably attached to the tip of the body, and the brush is applied to the top surface of the tooth. It is composed of a toothbrush and a brush provided at the tip of the handle, and is detachably attached to the tip of the body on both sides of the central toothbrush and is attached at an angle toward the period of time, and the brush of the central toothbrush is attached to the tooth. A drive that vibrates or pushes and pulls at least one of the central and bilateral toothbrushes built into the body and the bilateral toothbrushes that are applied to the inner and outer periodontal when applied to the top surface of the toothbrush. It is characterized by having a source.

One of the features of the present invention is that the three toothbrushes are located at the positions of the three vertices of the triangle, and when the central toothbrush is applied to the top surface of the tooth, the two-sided toothbrushes are applied to the inside and outside of the periodontal disease. At the point.
As a result, the toothbrush can be applied to the outer and inner gums and periodontal pockets at the same time, and the plaques in the outer and inner periodontal pockets can be removed at the same time. Moreover, the toothbrush can be finely moved to brush the outer and inner gums at the same time.

At least one of the three toothbrushes may be vibrated or pushed and pulled with a short stroke, but if the central toothbrush is vibrated and the two toothbrushes are pushed and pulled with a short stroke, the periodontal pocket Plaque removal and brushing of the outer and inner gums can be reliably performed.

That is, the drive source,
A vibrator provided in the body that vibrates the brush applied to the top of the tooth by applying vibration to the handle of the central toothbrush, a drive motor built in the body, and a toothbrush handle with tips on both sides. A slider that is connected to the rear end and pushes and pulls the brushes of the toothbrushes on both sides with a predetermined short stroke, and a connecting pin is projected at an eccentric position on the surface, and the rear end of the slider is connected to the connecting pin by the drive motor. It should be composed of a rotating body that is rotated and reversed.

It is a top view which shows the preferable embodiment of the electric toothbrush which concerns on this invention. It is a side view which shows the said embodiment. It is sectional drawing which shows the said Embodiment. It is sectional drawing side view which shows the said embodiment. It is a figure which shows the state of the toothbrush with respect to the tooth, the gum and the periodontal pocket in the said embodiment. It is a figure which shows the relationship between the toothbrush and the attachment in the said embodiment.

Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 6 show preferred embodiments of the electric toothbrush according to the present invention. In the figure, the grip (body) 10 has a tubular shape that can be gripped by the user with one hand, an insertion port 10A is formed at the tip of the grip 10, a packing 28 is provided at the insertion port 10A, and the packing 28 is provided with a packing 28. The attachments 30, 21, 22 are inserted, and the handles 11B, 12B, 13B of the toothbrushes 11, 12, 13 are inserted into the attachments 30, 21, 22, and the attachments 30, 21, 22 and the handles 11B, 12B, 13B are inserted. It is prevented from coming off by fitting the unevenness (for example, 11C in FIG. 6), and as shown in FIG. 5, the central toothbrush 13 is set to face the top surface of the tooth 33, and the toothbrushes 11 and 12 on both sides are set. It is tilted toward the periodontal 31.

Further, a gap adjusting screw 17 and 18 and a vertical adjusting screw 27 are provided at the tip of the grip 10, and the gap between the double-sided toothbrushes 11 and 12 with respect to the central toothbrush 13 can be adjusted by the gap adjusting screw 17 and 18, and the vertical adjusting screw 27 can be adjusted. The vertical position of the central toothbrush 13 can be adjusted by.

Further, an oscillator 20 is built in the grip 10, and the oscillator 20 vibrates the handle 13B of the central toothbrush 13.

Further, a drive motor 25 is built in the grip 10, a speed reducer 24 is connected to the rotating shaft of the drive motor 25, and a transmission mechanism 29 including, for example, a pair of bevel gears and an output roller is connected to the output shaft of the speed reducer 24. Is connected, and the output of the speed reducer 24 is transmitted to the rotating body 23.

Rotating plates 23B are fixed to the upper and lower surfaces of the rotating body 23, connecting pins 23A are projected at eccentric positions of the upper and lower rotating plates 23B, and attachments (slider) 21 of toothbrushes 11 and 12 on both sides are projected on the connecting pins 23A. , 23 are rotatably connected to each other, rotated and reversed by the drive motor 25, and the toothbrushes 11 and 12 on both sides are pushed and pulled with a predetermined short stroke.
