ORAL IRRIGATOR

To provide an oral irrigator.SOLUTION: An oral irrigator includes: a storage unit to store water; a pumping unit to pump water of the storage unit; a nozzle unit to inject the water pressurized by the pumping unit into an oral cavity; and a controller to control operation of the pumping unit. The controller stores a pattern in which an initial stage of gradually increasing a load of the pumping unit, a preliminary cleaning stage of maintaining an injection pressure of the water at a first pressure for a predetermined time, a full-scale cleaning stage of maintaining the injection pressure of the water at a second pressure higher than the first pressure for a predetermined time, and a final cleaning stage of maintaining the injection pressure of the water at a third pressure lower than the second pressure for a predetermined time are sequentially performed. The load of the pumping unit is automatically controlled based on the pattern according to a one-time input of an operation signal.SELECTED DRAWING: Figure 2 【課題】本発明は口腔洗浄器に関する。【解決手段】水を貯蔵する貯蔵部と、上記貯蔵部の水をポンピングするポンピング部と、上記ポンピング部によって加圧された水を口腔に噴射するノズル部と、上記ポンピング部の作動を制御する制御部と、を含み、上記制御部は、上記ポンピング部の負荷を徐々に増加させる初期段階、水の噴射圧力を第１圧力に一定時間保持する予備洗浄段階、水の噴射圧力を上記第１圧力より高い第２圧力に一定時間保持する本格洗浄段階、水の噴射圧力を上記第２圧力より低い第３圧力に一定時間保持する仕上げ洗浄段階が順に行われるパターンを保存し、作動信号の１回性の入力によって上記ポンピング部の負荷を上記パターンに応じて自動的に制御する。【選択図】図２
