Gaseous medium e.g. oxygen, filling device for aquarium, has mixing chamber with channels having inlet and outlet ports, where surface having inlet port is placed in preset position to liquid feeding device that ejects water to surface

摘要

The device has a mixing chamber (12) with channels running in parallel and separated from each other by partitions. The channels have inlet and outlet ports, where a surface (12a) containing the inlet port is placed in a preset position to a liquid feeding device that ejects water to the surface (12a). The surface (12a) is within the gaseous medium, and a surface (12b) exhibiting the outlet port is inside or outside the liquid medium.
