Claims (11)
- 電動歯ブラシであって、
ブラシヘッドに対して非垂直の角度で前記ブラシヘッドのブラシ毛ホルダの取り付け面に取り付けられた複数本のブラシ毛を含むブラシヘッドと、
前記ブラシヘッドに取り外し可能に取り付けられ、前記ブラシヘッドの前記取り付け面に垂直な回転軸を中心に回転可能な前記ブラシヘッドに取り付けられた前記複数本のブラシ毛を駆動するように構成されたリニアモータを含む、ハンドルであって、前記複数本のブラシ毛は、少なくとも1つの回転周波数で、前記ブラシヘッドに対して時計回り及び反時計回りに回転可能であり、前記少なくとも1つの回転周波数は、周波数閾値以上である、ハンドルと、を備え、
前記ブラシヘッドは、ブラシ毛が接触面と接触する動作中に、前記所定の回転周波数に対応する1つ以上の振動周波数で振動することにより、前記複数本のブラシ毛の前記回転と同期して、前記接触面に向かって及び前記接触面から離れる方向に動くように配置され、
前記1つ以上の振動周波数は、前記複数本のブラシ毛の回転周波数である基本周波数及び/又は前記基本周波数の倍数を含み、
前記リニアモータは、モータハウジングと、長手方向に沿って直線振動するように取り付けられた電機子と、固定子と、前記長手方向に沿って直線振動するように取り付けられた二次質量ユニットと、を有し、
前記リニアモータは、前記リニアモータに連結された駆動シャフトを介して直線振動運動を提供するように配置され、直線運動は前記ブラシヘッドに伝達される、電動歯ブラシ。 - 前記複数本の前記ブラシ毛の特性は、ブラシ毛密度、前記ブラシヘッドに前記複数本のブラシ毛が取り付けられる角度、並びに屈曲力及び座屈力をもたらす、前記複数本のブラシ毛の剛性のうちの少なくとも1つを含む、請求項1に記載の電動歯ブラシ。
- 前記リニアモータは、前記複数本のブラシ毛を、第1の時間間隔中に時計回りに回転させ、第2の時間間隔中に反時計回りに回転させるように構成されており、前記所定の回転周波数に対応する期間は、前記第1の時間間隔と前記第2の時間間隔との組み合わせを含む、請求項1又は2に記載の電動歯ブラシ。
- 前記複数本のブラシ毛は、前記ブラシヘッドに対して非垂直の角度で前記ブラシヘッドに取り付けられる、請求項1~3のいずれか一項に記載の電動歯ブラシ。
- 前記ブラシヘッドは、ブラシ毛接触力の標準偏差に対応する量を前記接触面に向かって、及び前記接触面から離れる方向に動く、請求項1~4のいずれか一項に記載の電動歯ブラシ。
- 前記ブラシヘッドの振動振幅は、前記接触面に印加される荷重が閾値量を上回って増加するにつれて増加し、具体的には、前記閾値は0.8N~1.0Nである、請求項1~5のいずれか一項に記載の電動歯ブラシ。
- 前記ブラシヘッドと、ブラシネックと、を含むリフィルを更に備え、前記リフィルは前記電動歯ブラシハンドルに取り外し可能に取り付けられ、前記リフィルが前記電動歯ブラシハンドルに取り付けられるとき、前記リフィルの内側表面と前記電動歯ブラシハンドルの外側表面との間の距離は、0.16mm未満である、請求項1~6のいずれか一項に記載の電動歯ブラシ。
- 前記リニアモータは、前記複数本のブラシ毛を、時計回り及び反時計回りに所定の回転角度回転させるように構成されており、前記所定の回転周波数は100Hzより高い、請求項1~7のいずれか一項に記載の電動歯ブラシ。
- 前記ハンドルは、光源と、圧力センサと、を更に含み、前記光源は、前記圧力センサによって検出された圧力の変化に応答して色を変えるように構成されている、請求項1~8のいずれか一項に記載の電動歯ブラシ。
- 前記ブラシ毛特性は、前記振動量が、第1の印加力閾値を下回る振動量から前記第1の印加力閾値を上回る振動量へとほぼ3倍になるように設定され、具体的には、前記印加力の標準偏差として表される前記振動量は、前記第1の閾値を0.1N~0.15N下回り、前記第1の閾値を上回る前記振動量は0.35N~0.45Nであり、前記第1の閾値は0.8N以上である、請求項1~9のいずれか一項に記載の電動歯ブラシ。
- 電動歯ブラシのブラシ毛駆動の脈動を提供する方法であって、
電動歯ブラシハンドルに含まれるモータによって、歯車構造に、ブラシヘッドに含まれる複数本のブラシ毛を、周波数閾値以上の回転周波数で前記ブラシヘッドに対して時計回り及び反時計回りに回転させることであって、前記複数本のブラシ毛は、前記ブラシヘッドに対して非垂直の角度で前記ブラシヘッドに取り付けられている、ことと、
前記複数本のブラシ毛が回転するときに、前記モータ及び前記歯車構造によって、前記所定の回転周波数に対応する1つ以上の振動周波数で振動させることにより、前記複数本のブラシ毛の前記回転と同期して前記ブラシヘッドを接触面に向かって、及び前記接触面から離れる方向に動かすことと、を含み、
前記1つ以上の振動周波数は、前記複数本のブラシ毛の回転周波数である基本周波数及び/又は前記基本周波数の倍数を含む、方法。
