Description
オリフィス板を貫く少なくとも1つのオリフィス開口部を持ったオリフィス板をその中に有するスプレーヘッド筐体;スプレーヘッド筐体に液体を届けるための液体ライン(line)システムであって、オリフィス開口部を通る液体の流量が、液体がオリフィスを通り液体流としてそこから出るオリフィスの大きさに対し十分大きいシステム;及び筐体中の少なくとも1つの気体開口部を通ってスプレーヘッド筐体に気体を届けるための気体システムであって、気体流が、液体流を分解し、歯の洗浄をするために、液体流を毎秒25mより大きい十分な速度と十分な大きさとを有する液滴噴霧にするのに十分な速度と流量でオリフィス開口部から液体流に衝突するような気体開口部を通る気体流に対して、スプレーヘッドの内部が配置される気体システム。
Claims (7)
