A kind of strength pump configuration of what is closed in this creation system,It specifically includes that an inside has the ontology of room,The ontology is equipped with the lower end surface of a upper surface and the corresponding upper surface,The upper surface is equipped with an air inlet pipe and an outlet pipe respectively,The air inlet piping, which connects, sets an air supplies,The outlet pipe to by the ontology water send out,The lower end surface system is equipped with a water inlet,And a non-return valve is equipped on the inside of the water inlet,The state for closing or opening the water inlet is presented by the internal and external pressure difference of the ontology in the non-return valve,To adjust the water that the water of outside enters the ontology； Thereby,This creation can be applicable to culturing jar water circulation,Water is set to reach dual aeration effect,And water circulation is not blocked,The benefits of having both energy conservation and environmental protection.本創作係關於一種氣力泵結構，其主要包括：一內部具有容室之本體，該本體設有一上端面及對應該上端面之下端面，該上端面分別穿設有一進氣管及一出水管，該進氣管係接設一空氣供應源，該出水管用以將該本體內之水送出，該下端面係設有一進水口，且該進水口內側設有一逆止閥，該逆止閥藉該本體之內外壓力差而呈現關閉或打開該進水口之狀態，以調節外部之水進入該本體之水量；藉此，本創作可應用在養殖缸水循環，使水達到雙重曝氣效果，且水循環不阻塞，兼具節能環保之效。
