The utility model provides a sport oxygen -increasing machine for the problem that the water action is difficult to maintain abundant dissolved oxygen volume of dialling of oxygen -increasing machineis known well in the solution. It contains: a sport component, this sport component have a jet flow pipe and a lid, and this jet flow pipe's one end combines this lid, form an acceleration space between this jet flow pipe and this lid, and first -class road junction is established to this jet flow pipe's the other end, a water conservancy diversion component, this water conservancy diversion component have a honeycomb duct, and an exit end of this honeycomb duct stretches through in this acceleration space, form a flow guide clearance between this runner mouth of this exit end and this jet flow pipe, reaching one and pouring into the component into, should pour into the component into and pierce through this jet flow pipe's pipe wall and communicate this acceleration space, the fluid poursinto leading -in this acceleration space of component into from this, in this flow guide clearance formation low -voltage state high -speed relatively, makes the poor guide gas of this exit end generate pressure pass through.一種噴流增氧機，用以解決習知增氧機的撥水動作難以維持充分溶氧量的問題。係包含：一噴流元件，該噴流元件具有一噴流管及一蓋體，該噴流管之一端結合該蓋體，該噴流管與該蓋體之間形成一加速空間，該噴流管之另一端設一流道口；一導流元件，該導流元件具有一導流管，該導流管之一出口端穿伸於該加速空間，該出口端與該噴流管之該流道口之間形成一導流間隙；及一注入元件，該注入元件穿透該噴流管之管壁且連通該加速空間，流體自該注入元件導入該加速空間，於該導流間隙形成相對高速低壓狀態，使該出口端產生壓力差導引氣體通過。
