The blades 817 can be directly protruded on the inner circumferential surface of the casing part 811, which can also generate upward force when rotating. The negative pressure suction below. In addition, since the blades 817 that can be driven to generate downward negative pressure suction in the air inlet passage 41 have many shapes, for example, they can be straight blades that are inclined up and down, so during implementation, the blades 817 are not This is limited to the above aspect, and during implementation, only one blade 817 may be provided in the casing portion 811 .

Furthermore, in this embodiment, the water rejection portion 822 of the lower impeller 82 is a right cross-shaped piece, but during implementation, it can also be changed to a spiral cross-shaped piece. In addition, the lower impeller 82 does not necessarily need to be provided with the blade portions 823 .

In summary, through the structural design of the water guide plate 5 installed and fixed on the floating frame mechanism 2 and located on the water surface, as well as the water lifting assembly 6 and the lower water lifting assembly 6 that can be connected and synchronously rotated outside the shaft tube 4 The structural design of the flushing assembly 7 and the impeller assembly 8 can utilize the cooperation of the water guide plate 5 and the water lifting assembly 6 to lift the upper water body upward and splash and roll around to spread, and then contact the air to cause the waterfall. , increasing the dissolved oxygen content of the upper water body. The downflush assembly 7 is further used to drive the oxygen-rich upper water body to flow downward and mix with the middle and lower water bodies to increase the dissolved oxygen content of the middle and lower water bodies. At the same time, the impeller assembly 8 is used to disperse the air sucked downward through the shaft tube 4 into bubbles distributed in the lower water body, thereby greatly increasing the amount of dissolved oxygen in the lower water body.

Therefore, the balanced water pump of the present invention can not only drive a large amount of water in the upper and lower water bodies of the pool 900 to increase the amount of dissolved oxygen, but can also simultaneously drive the upper, middle and lower water bodies of the pool 900 to generate large-scale up and down mixed flows. , and can increase the dissolved oxygen content of the pool 900 more efficiently, and can indeed improve the shortcomings of the existing water pump.
