次に、図7A,図7B,図9A,図9Bおよび図11A−図11Cを参照し、第2操作アセンブリ322を詳細に説明する。この第2操作アセンブリ322は、第1操作アセンブリ122と類似するが、いくつかの構造上の相違点を有してもよい。しかし、いくつかの実施態様においては、それら2つのアセンブリ122,322は、互いに同じであってもよい。第2操作アセンブリ322は、第2の把持強化部材358と、第2操作部362と、第2ベゼル366とを有してもよい。さらに、改善用流体500が、第2ベゼル366と第2操作部362との間に収容される。
次に、口腔洗浄器100のすべてのアセンブリを説明する。図3A−図5を参照すると、ポンプ・アセンブリ128と、圧力アセンブリ130と、パワー・アセンブリ144と、モータ126とが、ハウジング103内において、組み付けられて接続される。例えば、ポンプ・バルブ135がポンプ本体部136内に収容され、駆動リンク(図示しない)がギヤ・アセンブリ(gear assembly、かみ合わされた複数のギヤより成る組立体など)(図示しない)内に収容されてモータ126の駆動シャフト(図示しない)に接続され、シャシ132がハウジング103の底面に強固に固定される。ポンプ入口134が、ポンプ本体部136のトップ入口上に配置され、そのトップ入口に接続される。圧力アセンブリ130の圧力バルブ150がポンプ本体部136に接続される。例えば、圧力バルブ150は、図5に示すように、ポンプ本体部136の空洞137内に収容される。
これまでの説明は広範な用途を有する。例えば、この書類に開示されているいくつかの例は、2つの操作アセンブリに焦点を当てられているが、理解すべきことは、この書類に開示されているいくつかの概念は、他の口腔洗浄器にも等しく適用されてもよいということである。したがって、いかなる例についての上記の説明も例示にすぎないことを意図されており、明細書の開示の範囲または特許請求の範囲を含む開示の範囲がそれらの例に限定されることを示唆することを意図されていない。
