[0025] The principle is that the waterwheel increases oxygen first, and uses the outlet pipe to guide the water flow to impact the fan blades to form water splashes, increase the contact between the water flow and the air to increase oxygen, and then the fan blades rotate around the installation axis under the impact of the water flow. The movement of the fan blades stirs the water in the collection pool, which will also stir up water splashes to increase oxygen. Further, using aerated waterfall air to increase oxygen, the water from the water pipe is injected into the water receiving trough. During the water injection process, downward pressure is applied to the support spring to drive the water receiving trough downward. After it descends to a certain position, the top of the top rod hits the drain gate to bring the drain gate up. At this time, a large amount of air under the drain gate rushes into the water receiving trough and pushes the drain gate upward. At this time, the water in the water receiving trough will flow out quickly and in large quantities. Due to the fast outflow speed, the spring will push the water receiving trough upward. After the water flows to a certain extent, the drain gate loses the impact of the air and will close naturally. This is a process of the water receiving trough up and down. The up and down movement of the water tank is supported by the movable plate. The up and down movement of the movable plate drives the contraction of the airbag formed between the movable plate, the capsule sheet and the bottom plate and the top plate of the support box 7. The contraction of the airbag forms an air pump, which drives the outside air to continuously enter the aerobic pool to increase oxygen. Automation, continuity, and energy-free.

[0026] Furthermore, in order to ensure quality, the capsule 10 is made of elastic and corrosion-resistant butyl rubber material. The support spring 8 is arranged on the inner side of the capsule 10 to avoid the risk of oxidation of the support spring when it encounters water.

[0027] Furthermore, a vertical chute 19 is provided on the side wall of the water receiving trough 16, and a connecting plate 20 that can slide up and down is provided in the chute 19. A limit block 21 is provided at the upper end of the connecting plate 20 to limit the downward limit position of the connecting plate 20, and the lower end of the connecting plate 20 is connected to the end of the drain gate 17 away from the hinge direction through a flexible rope 22. A floating ball 23 is provided at the upper end of the connecting plate 20, and a platform 24 is provided at the upper end of the chute 19 close to the side wall of the water receiving trough 16. A card plate 25 is provided at the upper end of the connecting plate 20. The middle part of 25 is hinged on the connecting plate 20, and a push spring 26 is arranged on the connecting plate 20 to push the lower end of the card plate 25 to swing toward the side wall direction of the water receiving trough 16. The upper end of the card plate 25 has an end 27 bent toward the side wall direction of the water receiving trough 16. A push plate is arranged at the water outlet position of the water conduit 6, and a push head 28 is arranged on the push plate. When the water receiving trough 16 moves upward, the end 27 touches the push head 28, and the push head 28 pushes the lower end of the card plate 25 to swing toward the side wall direction away from the water receiving trough 16.

[0028] Because the water pipe discharges water continuously, the drain gate is prevented from closing prematurely during the rising process of the water tank under the impact of the water flow, so the above structure is used for control. The principle is that when the drain gate is closed, the drain gate receives the internal water pressure of the water tank. Even if the float receives the buoyancy of the water, it is not enough to open the drain gate. However, after the drain gate is opened under the action of the top rod, the float will quickly pull up the connecting plate. After the connecting plate is pulled up, the lower end of the card plate will move toward the side wall of the water tank under the support of the push leaf spring. At this time, the lower end of the card plate will be supported on the platform. Even if the water tank moves up, the drain gate will not be closed because of the traction of the flexible rope. However, after the water tank rises, it encounters the end head hitting the push head. Under the push of the push head, the lower end of the card plate withdraws from the platform. At this time, the drain gate will close downward, and the water tank starts to store water again. And so on.

[0029] Furthermore, the water pipe 6 includes an upper branch pipe and a lower branch pipe, and the upper branch pipe and the lower branch pipe are connected through a vertical guide groove 29. A piston is arranged in the guide groove 29, and the piston is connected to the water receiving trough 16 through a connecting rod 30. When the water receiving trough 16 moves upward, the piston is pushed upward to block the upper branch pipe, and when the water receiving trough 16 moves downward, the piston is pushed downward to block the lower branch pipe. In this way, two sets of support boxes, support springs, water receiving troughs and other devices for waterfall gas can be set, and continuous control can be achieved through the up and down movement of the piston, respectively, so that the waterfall gas efficiency is significantly improved.

[0030] Furthermore, a plurality of support rods 15 are provided, and the support rods 15 are evenly distributed around the circumference of the movable plate 9 , the water receiving trough 16 is in a cylindrical shape, and the support rods 15 are supported at the bottom of the water receiving trough 16 .

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
