when oxygen increasing work is required, the centrifugal turbine fan (9) is started, so that the air blown out by the centrifugal turbine fan (9) is completely led into the transition air cavity (64) through the air outlet (15), compressed air with a higher atmospheric pressure is generated along with the increase of the air pressure in the transition air cavity (64), water in the compressed air diversion cavity (12) is squeezed by the compressed air due to the fact that the transition air cavity (64) and the compressed air diversion cavity (12) are in a conduction state, the water in the compressed air diversion cavity (12) is discharged into the conical cover cavity (61) of the umbrella-shaped air bubble cap (53) from the air outlet (23) through the hard air pipes (1) until the water in the compressed air diversion cavity (12) is completely squeezed by the compressed air to be exhausted, the compressed air diversion cavity (12) forms a cavity filled with the compressed air, and meanwhile air bubbles are gradually accumulated in the conical cover cavity (61), until the conical cover cavity (61) forms a cavity, because the lower end of the conical cover cavity (61) is open, along with the accumulation of bubbles in the conical cover cavity (61), the gas in the conical cover cavity (61) overflows from the lower contour edge of the conical cover cavity (61) in the form of bubbles, and because a cavity structure is added, the buoyancy borne by the whole self-rotating floater (2) can be increased, the whole self-rotating floater (2) slowly floats in the process of gradually discharging water in the compressed air diversion cavity (12) until the lower half sections of the oxygen-increasing water-beating blades (11) are immersed in the water when the compressed air diversion cavity (12) and the conical cover cavity (61) are in a complete cavity state, and the upper half sections of the oxygen-increasing water-beating blades (11) are positioned above the horizontal plane; at the moment, as the air in the compressed air diversion cavity (12) is accumulated continuously and the pressure is increased gradually, the compressed air in the compressed air diversion cavity (12) is sprayed out in the form of sprayed gas through the air outlets (23) at the lower ends of the hard air pipes (1), because the height of the midpoint of each air outlet (23) is equal to the height of the profile surface (66) at the lower end of the umbrella-shaped air bubble cap (53), and the height of the liquid level in the umbrella-shaped air bubble cap (53) is just overlapped with the profile surface (66) at the lower end of the umbrella-shaped air bubble cap (53) in the working state, the lower half part of the air outlet (23) at the lower end of the hard air pipe (1) is immersed in the water, and the upper part is positioned above the liquid level in the umbrella-shaped air bubble cap (53), therefore, the gas sprayed out from the air outlets (23) can blow the liquid level in the conical cover cavity (61) into a large amount of splashed water, and the relatively compressed air, therefore, after the compressed air is in large-area contact with the water bloom, a large amount of oxygen is dissolved in the water, and the oxygen increasing effect is improved; the gas in the conical cover cavity (61) in the water is continuously accumulated, the gas which is excessive in the conical cover cavity (61) continuously overflows and floats upwards from the lower contour edge of the conical cover cavity (61) in the form of bubbles, the bubbles further contact with the water body to be dissolved in the floating process, and oxygen contained in the bubbles is partially dissolved in the water, so that the effect of further increasing the oxygen of the pond water is achieved;
meanwhile, the reaction generated by the gas sprayed from the gas outlet (23) of each bent pipe (22) drives the self-rotating floater (2) to continuously rotate along the reverse direction of the gas spraying, so as to drive each oxygen-increasing water-beating blade (11) to rotate along with the self-rotating floater (2), each oxygen-increasing water-beating blade (11) rotates and stirs the water body, the effect of water body flowing is promoted, bubbles floating upwards below are quickly dispersed and emerge in a dispersed mode, the phenomenon that the oxygen dissolution rate of the bubbles is reduced due to concentrated dissolution is effectively avoided in the form of bubble dispersion, simultaneously, splashing water flowers can be generated in the process that each oxygen-increasing water-beating blade (11) rotates and stirs the water body, so as to promote the oxygen in the water surface air to be dissolved in the water, meanwhile, the whole self-rotating floater (2) can float upwards for a certain distance in the working process, and the heights of the centrifugal turbo fan (9) and other electric, effectively preventing the generated splashing shower head from falling into the floating cavity (8) of the shower head.
