Due to the constant influx of water, the fluid initially acquires a force away from the inlet 21. The fluid then enters the water flow path 61 and is cut and stirred by the cutting blades 41 rotating together with the rotation shaft 51. Eventually, the fluid will be released at the outlet 22.

Preferably, referring to fig. 1, a floating frame 81 is disposed at the air inlet 11, the air inlet 32 is disposed in the floating frame 81, and at least one buoy 80 is connected to the floating frame 81. The floating frame 81 ensures that the air intakes 32 float on the liquid surface, so that liquid cannot enter the air flow channel 52 from the air intakes 32. The float bowl 80 will increase the buoyancy of the floating frame 81, thereby ensuring that the floating frame 81 floats on the liquid surface.

Preferably, two floating cylinders 80 are arranged on the floating frame 81, and the two floating cylinders 80 are arranged on two opposite side surfaces of the floating frame 81.
