案されている。2. Description of the Related Art In a conventional manual toothbrush, it is not easy to set a contact angle of a user with a brush tooth in order to perform correct brushing, and it is also difficult to apply force to the toothbrush. It was difficult and often brushed too much with only the surface of the teeth. With such brushing, the teeth are not sufficiently cleaned, and the tooth surfaces may be worn. In order to solve this problem, the shape and size of the brush part are optimally set for cleaning the teeth, and the brush part is vibrated in contact with the teeth with a uniform moderate force by the motor provided in the handle. There has been proposed an electric toothbrush that enhances the cleaning effect of teeth and does not wear the tooth surfaces due to excessive frictional force.

れるので、歯のクリーニング効果が高められる。In this case, the inertia resistance of the motor 5 is adjusted by the weight 6, so that the motor 5 starts to rotate slowly and safely without suddenly starting to rotate.
It reaches a predetermined rotation speed and rotates stably. The eccentric movement of the weight 6 accompanying the rotation of the motor 5 causes the brush portion 2 with the toothpaste to vibrate, and the user can adjust the contact position and the inclination of the brush portion 2 with respect to the teeth by a simple operation. Cleaning is performed. At this time, the intraoral electrode 4 and the handle electrode 3
In the meantime, a current of several hundred μA flows through the body fluid of the user, and the plaque is removed by the ionic effect of the current, so that the tooth cleaning effect is enhanced.
