Technical Problem
[0003]抽滤完成时，由于瓶内仍为负压状态，导致抽滤口与真空泵橡胶管连接较难断开，当快速断开连接时，气压的剧烈变化甚至会导致瓶内液体沿着抽滤口喷出；当操作人员的不正确操作先关闭真空泵电源或者意外断电，真空泵中的液体会倒流入抽滤瓶中，导致滤液污染
Benefits of technology
[0013]与现有技术相比，本申请的简易防倒吸抽滤瓶的设置第一抽滤管和第二抽滤管，使用时，外部的真空抽滤泵通过橡胶管与第二抽滤管进行连接，手动将盖体拨至与第一抽滤管的末端口贴合，待瓶身内负压达到最大时，在大气压强作用下，盖体即可完全固定于第一抽滤管末端口，继续完成后续抽滤工作；在操作人员先关泵再拔管错误操作或者意外断电情况下，瓶内负压减小，外部的真空抽滤泵中循环水通过橡胶管回流至第二抽滤管进入第一抽滤管，盖体由于自身重量及水的重量会自行与第一抽滤管的末端口分离，循环水受自身重量作用由第一抽滤管的末端口排出至外部废液缸中收集处理。
