TaskAlso in the central part of the tooth that does not need to be strongly polished, dent and plaque are easy to accumulate, and the interdental part that needs to be strongly polished is uniformly polished without distinction, the disadvantages of conventional toothbrush and electric toothbrush However, I would like to obtain an appropriate toothpaste effect.For this purpose, prepare a plurality of small brush bundles and driving parts as a set, detect the interdental part using a position sensor or a pressure sensor, and operate so as to operate only when it is detected that the brush tip part is in a polishing place .SOLUTION:The brush head is constituted by a plurality of parallel movable brush bundles, a motor for individually driving the brush bundle, and a detection mechanism for detecting a groove portion such as a tooth, and the brush bundle in the interdental part is rotated, vibrated, By doing so, take dirt and plaque between the teeth.(FIG.【課題】強く磨く必要のない歯の中央部分も、汚れや歯垢やがたまりやすく、強く磨く必要がある歯間部も、区別することなく一律に磨いてしまうという、従来の歯ブラシ、電動歯ブラシの欠点をただし、適切な歯磨き効果を得たい。そのために、小さなブラシ束と駆動部をセットとして複数個用意し、位置センサーもしくは圧力センサーを用いて、歯間部を検知し、ブラシ先端部が磨く場所にあると検知したときのみ作動するようにする。【解決手段】ブラシヘッドを複数の平行移動できるブラシ束によって構成し、ブラシ束を個別に駆動するモーターと、歯などの溝部を検出する検知機構を備え、歯間部にあるブラシ束を回転、振動、味噌擂り運動させることで、歯間にある汚れや歯垢をとる。【選択図】 図5
