A device for increasing the oxygen content in water is connected to a water diversion pipeline for high-pressure water flow. The device includes a guide filter and an oxygen increasing release connected to the front end of the guide filter.The pressurized water flow in the water diversion pipeline becomes the filtering water flow through the guide filter. When the filtering water flow passes through the dissolved oxygen space of the oxygen increasing release device, it is mixed with the external air introduced into the dissolved oxygen space to become the oxygen increasing water flow and then released.This creation can be applied to aquaculture pond for fish and shrimp to increase oxygen content in water, improve water quality and remove fish odour.一種增加水中含氧量的裝置，該裝置連接於一供高壓水流流通的引水管路，該裝置包含一導引過濾器以及連接在該導引過濾器前端的增氧釋出器。該引水管路中的加壓水流通過該導引過濾器成為過濾水流，該過濾水流通過該增氧釋出器的溶氧空間時與被引入該溶氧空間中的外部空氣混合成為增氧水流後釋出。本創作可應用於養殖魚蝦的水池，用以增加水中含氧量，改善水質，去除魚類臭土味。
