Abstract
Description
まず、実施の形態に係る電動歯ブラシ10について説明する。図1は、実施の形態に係る電動歯ブラシ10の概略構成を示す斜視図である。図2は、実施の形態に係る電動歯ブラシ10の概略構成を示す分解斜視図である。ここで、電動歯ブラシ10に備わる軸体22の延設方向をZ軸方向とする。また、Z軸方向に直交する方向であって、電動歯ブラシ10に備わるブラシ30の延設方向をX軸方向とし、Z軸方向及びX軸方向の両者に直交する方向をY軸方向とする。なお、使用態様によってはZ軸方向が上下方向にならない場合も考えられるが、以下では説明の便宜のため、Z軸方向を上下方向として説明する。
次に、電動歯ブラシ10の動作について説明する。
以上のように、本実施の形態に係る電動歯ブラシ10は、ブラシ30が取り付けられる軸体22と、ブラシ30の刷掃動作のため、軸体22を動作させる主駆動部23と、軸体22を偏心させる副駆動部24とを備えている。
上記実施の形態では、分銅付き回転モータと回路基板251とが、リニアアクチュエータを基準として同じ側に配置されている場合を例示した。この変形例1では、別のレイアウト例について説明する。
上記実施の形態では、分銅付き回転モータの回転軸が、リニアアクチュエータによる往復直線運動方向に対して平行に配置されている場合を例示した。この変形例2では、別のレイアウト例について説明する。
上記実施の形態では、押さえ部263が金属製の板状部材である場合を例示した。押さえ部263が金属製であると、分銅243が回転することで金属同士が擦れあってしまう場合がある。これを避けるべく、この変形例3では、押さえ部における分銅243に触れる部分を樹脂成形品とした場合について説明する。
以上、本発明に係る電動歯ブラシについて、上記実施の形態及び変形例1、2に基づいて説明したが、本発明は、上記実施の形態及び変形例1、2に限定されるものではない。
