A culture siphon structure.Ute pointed out that the water tank is equipped with a water outlet seat.The water outlet seat is provided with a water outlet hole.A cover is arranged above the water outlet hole.The bottom of the cover is provided with a plurality of through holes.The water outlet hole can be used for threading and locking a water outlet pipe.The water outlet pipe can be provided with a siphon.A water inlet seat is arranged above the siphon.The outer diameter of the water inlet seat is smaller than the inner diameter of the cover.To form a water inlet space,The water flows from the plurality of perforations of the cover from the bottom to the top.Then overflow from the water inlet seat to the siphon.A pipe joint is arranged under the water outlet pipe.The inner wall of the pipe joint is provided with an inward protruding broken surface.As a way to reduce the outlet area of the pipe joint,The siphon does not need to be bent.You can create a vacuum pull.It is characterized by.一種養殖虹吸結構，尤特指出水槽設有一出水座，所述出水座設有一出水孔，所述出水孔上方設有一罩蓋，所述罩蓋底部設有複數個透孔，所述出水孔可供穿設並鎖固一出水管，所述出水管可供穿設一虹吸管，所述虹吸管上方設有一進水座，所述進水座的外徑小於罩蓋的內徑，藉以形成一進水空間，水從罩蓋的複數個透孔先由下往上，再從進水座由上往下溢流至虹吸管中，所述出水管下方設有一管接頭，所述管接頭內壁設有一向內突出的破面，做為縮小管接頭的出水面積之用，讓虹吸管無需導接彎管，就可以產生真空拉力，為其特徵者。
