[0032] By installing an air intake device 5 at the top, and the air intake device 5 being arranged with a first exhaust pipe 510 and a second exhaust pipe 511 arranged opposite to each other at intervals, and an electric control valve 57 installed on the second three-way pipe 56 connecting the second air distribution pipe 58 and the third air distribution pipe 59, the air output on both sides can be automatically controlled. By emitting air intermittently, the oxygen content inside the pool is increased, while avoiding excessive algae growth caused by excessive oxygen.

[0033] The waste discharge structure 6 includes a filter base plate 61, side supports 62, a limiting plate 64, a slide 66, a collection hopper 67, a connector 68, a first pull rope 69, a second pull rope 610, and a pressure plate 612. The side supports 62 are located on both sides of the bottom of the filter plate. The surface of the filter base plate 61 has multiple slots for material leakage. The side supports 62 have an inner slide rail 63. The limiting plate 64 is located on the front and rear sides of the side supports 62. The side of the side supports 62 has a second slide groove 65. The two ends of the slide 66 are slidably disposed in the inner slide rail 63 of the side supports 62. The collection hopper 67 is located below the slide 66 and is slidably disposed relative to the bottom of the detachable water tank. The connector 68 is located on the left and right sides of the slide 66, and its output end extends outward through the second slide groove 65. The first pull rope 69 and the second pull rope 610 are connected to the slide 66. The ends are respectively set on the front and rear sides of the two connecting heads 68. By pulling the first pull rope 69 and the second pull rope 610 backward, the slide 66 is driven to move backward inside the slide rails on both sides, so that the collection hopper 67 at the bottom of the slide 66 collects the waste material remaining at the bottom of the oilcloth water tank 34 until the collection hopper 67 moves to the last side. Then, the entire slide 66 is pulled upward, and the slide 66 pushes out the top pressure plate 612 and is taken out upward through the through groove 611. Then, the waste material inside the collection hopper 67 is cleaned and then sent down through the through groove 611. Then, the pull rope is aligned with the second slide groove 65 and stored. Then, the through groove 611 is covered by the pressure plate 612 to prevent leeches from entering. The back top of the filter base plate 61 has a corresponding through groove 611 for the slide 66, and the pressure plate 612 is set in the through groove 611.

[0034] By incorporating a waste discharge structure 6 within the detachable filter tank, and a filter base plate 61 at the top, the waste discharge structure 6 allows for the collection of waste excreted by live food such as screws, which is then processed and the mesh size is controlled to prevent leeches from falling in. A slide 66 and a collection hopper 67 located below the filter base plate 61, in conjunction with the pulling of the first pull rope 69 and the second pull rope 610 on both sides, allow the slide 66 to move the collection hopper 67 back and forth, collecting the waste at the bottom. A through-slot 611 on the rear side of the filter base plate 61 allows the collection hopper 67 to be pulled upwards for easy waste discharge. Furthermore, the detachable water tank allows for easy cleaning of residual waste inside using pliers, further maintaining water quality and reducing the leech-borne disease rate.
