In this embodiment, the filter 1 is used to purify sewage and provide a good living environment for farmed fish. The outer cylinder 11, the inner cylinder 12 and the cylinder cover 13 are all made of plastic, and the outer cylinder 11, the inner cylinder 12 and the cylinder cover 13 cooperate with each other to form a closed annular filter chamber 15; the filter layer 14 is provided to filter impurities in the aquarium to achieve the purpose of purifying water quality; the first through hole 16 and the third through hole 18 are both circular holes with a diameter of 0.4 cm, and more than two first through holes 16 are evenly distributed in a ring shape on the outer bottom of the outer cylinder 11, and more than two third through holes 18 are evenly distributed in a ring shape on the top of the cylinder cover 13, thereby achieving a cleaning effect in which sewage enters through the first through hole 16 and is purified by the filter layer 14 and then discharged from the third through hole 18; the second through hole 17 is a square hole with a length of 0.4 cm and a width of 0.1 cm, and the inner wall of the inner cylinder 12 is sequentially provided with several layers of square holes evenly distributed in a ring shape from top to bottom. The air stone 2 is a cylindrical structure 4 cm high and 1 cm in diameter. It has a porous structure, allowing for all-round air pumping. The air pump 4 is 20 cm long, 15 cm wide, and 9 cm high. When the device is in use, the air pump 4 is placed outside the aquarium, and the filter 1 is placed at the bottom of the aquarium, connected by the ventilation tube 3.

[0021] Specifically, the filter layer 14 includes, from top to bottom, a quartz sand layer 141, an activated carbon layer 142, a filter cotton layer 143, and a bacterial roof layer 144. These layers are separated by a gauze mesh 145.

The mesh diameter of the gauze mesh 145 is 0.2 mm.

[0022] Specifically, the first through hole 16 is aligned with the bacterial house layer 144 , so that the sewage first enters the bacterial house layer 144 for the first level of filtration.

[0023] Specifically, an air flow regulating switch 42 is provided on the top of the air pump 4. In this embodiment, the air flow regulating switch 42 is a threaded flat cylindrical knob for regulating the pumping rate of the air pump 4.

[0024] Specifically, the vent pipe 3 includes a first air pipe 31, an airflow control switch 32, a second air pipe 33, and a third air pipe 34, which are connected in sequence. The free end of the first air pipe 31 is connected to the air outlet 41, and the free end of the third air pipe 34 is connected to the air stone 2. In this embodiment, the first air pipe 31, the second air pipe 33, and the third air pipe 34 are all plastic hoses, and the length can be tailored as needed. The airflow control switch 32 is a T-shaped plastic threaded knob that connects the first air pipe 31 and the second air pipe 33. It is used to control the airflow entering the filter 1 and can be adjusted by the user according to actual needs.

[0025] Specifically, there are two or more air outlets 41. In this embodiment, there are four air outlets 41, each of which is connected to a filter 1 through a vent pipe 3, so as to meet the aeration and purification needs of multiple aquariums at the same time.

[0026] Working Principle: When in use, first place the filter 1 at the bottom of the aquarium and place the air pump 4 on one side of the aquarium. Then start the air pump 4, which transports air through the vent tube 3 to the air stone 2. The air is converted by the air stone 2 into fine bubbles and evenly discharged. The bubbles enter the filter chamber 15 through the second through hole 17 and are discharged through the third through hole 18. This process drives the water to flow upward synchronously, allowing the sewage at the bottom of the aquarium to enter the filter chamber 15 through the first through hole 16 and be filtered by the filter layer 14. The purified water is then discharged from the third through hole 18 above, thus achieving water purification while aerating and providing a good living environment for farmed fish.

[0027] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application are also within the scope of protection of the present invention.
