This creation is about a breeding pond aerator, which is driven by a driving mechanism to rotate the upper and lower impellers. The upper and lower impellers are installed in the space formed by the upper and lower shells, and between the upper and lower shells. A partition is arranged to separate the upper space and the lower space, the upper and lower impellers are respectively arranged in the upper and lower spaces, and the partition has a through hole to connect the upper and lower spaces, and the upper space is connected with an air inlet pipe sleeve and enters The upper end of the tracheal sleeve extends out of the water surface, and a gas-liquid mixing tube is arranged on one side of the upper and lower shells, so that the partition extends a tongue. The tongue separates the inner end of the gas-liquid mixing tube from the upper and lower flow channels. The end of the lower flow channel and the adjacent outlet of the gas-liquid mixing pipe form a gas-liquid mixing channel； accordingly, through the adjustment of the aperture size or the number of the through holes on the partition, the amount of water from the lower space into the upper space is controlled, and the The air entering the upper space from the intake pipe sleeve is mixed, and finally transported to the gas-liquid mixing channel through the upper flow channel, and then mixed with the water in the lower flow channel in the gas-liquid mixing channel, and discharged out of the gas-liquid mixing channel to improve the culture pond The effect of oxygen content inside.本創作係有關於一種養殖池增氧機，係由一驅動機構帶動上、下葉輪轉動，上、下葉輪安裝在上、下殼體蓋合所形成的空間內，上、下殼體之間設置隔板隔設出上空間與下空間，上、下葉輪分別安置在上、下空間內，又隔板上具有貫穿孔連通上、下空間，上空間與一進氣管套銜接，且進氣管套的上端延伸出水面，上、下殼體的一側設置氣液混合管，令隔板延伸一舌片，舌片將氣液混合管內部的一端分隔出上流道、下流道，上、下流道終端、鄰近氣液混合管出口形成氣液混合流道；據此，透過隔板上的貫穿孔孔徑大小或貫穿孔數量的調整，控制水由下空間進入上空間的量，並與自進氣管套進入上空間的空氣混合，最後經上流道輸送至氣液混合流道，再與下流道的水於氣液混合流道中匯流混合，排出氣液混合流道外，達到提高養殖池內的含氧量的效果。
