Description
【考案の詳細な説明】 本考案は、口腔衛生装置の減圧機構に関する。[Detailed explanation of the idea] The present invention relates to a pressure reduction mechanism for an oral hygiene device.
口腔衛生装置は、虫歯の予防、歯ぐきのマツサージまた
は口腔内の炎症の泊ゆなどに使用される装置であり、口
腔内を洗浄しかつ治療に効果がある液体を貯留する貯留
槽と、その貯留槽内の液体を吸引、吐出して間欠流を起
こす液体付勢装置と、その液体付勢装置と貯留槽との間
に介在して液体付勢装置の吸引力によって開くチェック
弁と、前記液体付勢装置の吐出口に接続されて液体を噴
出し、吐出液路の開閉弁を有す把手とからなる。An oral hygiene device is a device used to prevent tooth decay, treat gum tissue, or treat inflammation in the oral cavity. A liquid urging device that suctions and discharges the liquid in the tank to generate an intermittent flow, a check valve that is interposed between the liquid urging device and the storage tank and opens by the suction force of the liquid urging device, and the liquid It is connected to the discharge port of the urging device to eject liquid, and includes a handle that has an on-off valve for the discharge liquid path.
従来の口腔衛生装置によれば、液体付勢装置を作動させ
ている際に把手の開閉弁を閉じて液体の噴出を止めると
、液体付勢装置の内圧が高くなる。According to the conventional oral hygiene device, when the on-off valve of the handle is closed to stop the ejection of liquid while the liquid urging device is in operation, the internal pressure of the liquid urging device increases.
その結果、モータに無理を強いることとなるので高トル
クモータを使用しなければならず、高価になるという欠
点があった。As a result, the motor is forced to work harder, requiring the use of a high-torque motor, which is disadvantageous in that it becomes expensive.
また、液体付勢装置の内圧が高いと、僅かな摩耗が生じ
ても圧力損失が大きくなり、さらに、水漏れが頻繁に起
る虞れがあるので噴出を止める際はモータスイッチを切
、るようにしなければならず、操作が煩わしく、手元に
開閉弁を設けても充分に活用されなかった。In addition, if the internal pressure of the liquid energizing device is high, even a small amount of wear will cause a large pressure loss, and there is a risk of frequent water leaks, so be sure to turn off the motor switch when stopping the jetting. The operation was cumbersome, and even if an on-off valve was provided at hand, it was not fully utilized.
