- 電動駆動アセンブリを含む柄部と、
ブラシヘッドアーム、及び、遠位端におけるブラシ要素を含む、ブラシヘッドアセンブリと、
前記ブラシヘッドアセンブリに装着されているばねアセンブリと、
前記ばねアセンブリの後端に配置された装着部材と、
前記装着部材の後面に装着された磁石と、
前記ばねアセンブリの後端が動くと前記磁石により生成される変化する磁場内に装着されたホール効果センサであって、前記ブラシ要素に対する圧力によって、前記ばねアセンブリの後端の変位に対応する前記ホール効果センサの出力が、無負荷状態から変化する、前記ホール効果センサと、
前記ホール効果センサの出力及びプロセッサ内に保存された情報に応じて、ブラシング動作の間に前記ブラシ要素にかけられる圧力を示す信号を生成する当該プロセッサと、
を有し、
前記ばねアセンブリと前記ブラシヘッドアセンブリとの装着は、前記ばねアセンブリの前端が前記ブラシヘッドアセンブリと装着することによりなされ、
前記磁石と対向する前記電動駆動アセンブリのモータにより、前記ばねアセンブリの長さ方向を軸として前記ばねアセンブリと前記ブラシヘッドアセンブリとが回転し、
前記ばねアセンブリの後端にあるベアリングが、ばね部材を介して筐体に装着され、
前記ブラシ要素に付与される圧力に応答し、前記ブラシヘッドアセンブリが前記ばねアセンブリに装着されている側の前記ばねアセンブリの前端近くの枢着点を支点として、前記ばねアセンブリの後端が前記圧力の付与方向とは反対方向に動く一方、前記ブラシヘッドアセンブリが前記圧力の付与方向と同じ方向に動き、
前記プロセッサは、前記ホール効果センサの出力を、少なくとも1つの予め確立された閾値と相関付け、第1の閾値を超える前記ブラシ要素に対する圧力に関するフィードバック情報をユーザに提供する、
電動歯ブラシ。 - 前記装着部材は鉄系金属を有する、請求項1に記載の電動歯ブラシ。
- 前記ブラシ要素に対する圧力により前記磁石が変位させられたときに前記磁石により生成される変化する磁場に対する前記ホール効果センサの感度を低減させるための、前記磁石と前記ホール効果センサとの間に配置された金属遮蔽部を含む、請求項1に記載の電動歯ブラシ。
- 前記金属遮蔽部は、約0.3mmの厚さを持つミューメタルである、請求項3に記載の電動歯ブラシ。
- 前記ブラシ要素に対する圧力は、歯に対してユーザが前記ブラシ要素を押し付けることによりもたらされる負荷と、ブラシング動作の間にユーザの唇及び頬によりもたらされる負荷と、を有する、請求項1に記載の電動歯ブラシ。
- 前記プロセッサは、幾つかのサイクルに亘って前記ホール効果センサの信号出力を平均化する能力と、前記信号出力からノイズをフィルタリングして除去するための能力と、を含む、請求項1に記載の電動歯ブラシ。
- 前記フィードバック情報はユーザにより認識可能な形態をとる、請求項1に記載の電動歯ブラシ。
