As shown in figures 1-3, when the self-cleaning device for the fish tank works, the whole filtering and oxygen-increasing unit 1 is immersed in the water body in the fish tank. The power connector 207 is externally connected with a power supply, when the loop is connected, a magnetic field excited in the electromagnetic coil 210 pushes the magnetic element 205 to move upwards, the magnetic element 205 moving upwards further pushes the rubber bowl 203 to move upwards, at the moment, the internal pressure of the air chamber 201 formed by the air chamber shell and the rubber bowl 203 is increased under the deformation and extrusion of the rubber bowl 203, partial air in the air chamber 201 is exhausted through the one-way air outlet valve 214, the exhausted air enters the air box 106 through the air duct 3 and is released through the air holes in the outer surface of the air box 106, and the released air is mixed with the water in the container shell 102 to form small bubbles. The density of the water mixed with a large amount of small bubbles is smaller than that of the water at the lower layer in the container shell 102, so that rising power is formed, the water in the container shell 102 is driven to rise, and the water is released into the water of the fish tank outside the container shell 102 after being filtered by the filter element 103 at the lower layer and the filter element 101 at the upper layer. Driven by the ascending water flow, the aquarium water outside the container shell 102 enters the area between the lower filter element 103 and the collecting box 109 through the water inlet 105 and the water nozzle 104. Solid impurities such as residual baits and excrement contained in the fish tank water body outside the container shell 102 can be filtered and intercepted by the lower-layer filter element 103, and then become clean, meanwhile, air released by the air box 106 generates bubbles in the container shell 102, the bubbles touch the bottom of the lower-layer filter element 103 and are broken and reduced, and the broken and reduced bubbles are combined with the clean fish tank water body in the process of continuously rising to form a plurality of micro bubbles, namely the oxygen-enriched water body is formed. In addition, the area between the lower filter element 103 and the collecting box 109 has a large water flow cross section, the fish tank water body outside the container shell 102 sprayed out by the water spray nozzle 104 suddenly enters the area, the flow rate suddenly drops, and the solid such as residual bait and excrement with high density suddenly loses large lifting force in the fish tank water body outside the container shell 102, and the solid can be settled in the collecting box 109 under the driving of bubbles generated by the air box 106 and the gravity action of the solid. Occasionally, the solid residue attached to the bottom surface of the lower filter element 103 can be separated from the lower filter element 103 under the dual actions of rapid washing of the water sprayed from the water nozzle 104 and the touch and rupture of the air bubbles generated by the air box 106, the lower filter element 103 can further continuously keep a clean state, and the separated solid residue can fall into the collection box 109 under the driving of the air bubbles generated by the air box 106. Under the double filtration of the upper filter element 101 and the lower filter element 103, the fish tank water body outside the container shell 102 is purified with excellent effect, the oxygen content in the whole fish tank water body is also improved under the action of the air box 106, and the good living environment in the fish tank is ensured.

The filtering and oxygen increasing unit and the gas pressurizing unit are communicated into a whole, so that the device is simple in structure and convenient to self-check, repair and replace; the gas pressurizing unit automatically supplies external air to the filtering and oxygen increasing unit under the combined action of the air chamber and the electromagnetic control system, water containing impurities in the fish tank enters the container shell, filtering and cleaning are completed under the action of the upper filter element and the lower filter element, and oxygen-enriched water is formed under the action of the external air released by the gas box, so that the device has the functions of filtering, oxygen increasing and self-cleaning simultaneously, and the trouble that the fish tank needs to change water frequently is avoided.
