International standard pool sizes are 50 meters long and 21 meters wide, and garden-mounted private pool sizes also tend to require more than 25 meters long and 11 meters wide, which greatly increases land costs and maintenance difficulties. Based on the above background, various swimming machines are available in the market, which utilize the circulating water flow to reduce the size of the swimming pool. The swimming machine needs a flat rectangular water outlet with long side length and short side length, and needs a larger water outlet area and a smaller water outlet speed. The water spraying device of the swimming machine mainly comprises a traditional axial flow water pump and a traditional centrifugal water pump. On one hand, the water outlet of the traditional water pump is smaller, the water flow speed is higher, and a rectangular water outlet with long side and short side can be formed only by introducing more flow guide devices, flow expansion devices and turning devices. These devices cause a local loss of water pressure, and when water flows through a local area of these pipes, the flow velocity and direction change sharply, and fluid particle impact occurs, which causes vortex, secondary flow, and separation and re-wall of the flow.
