[0003] Based on the above, in the prior art, the water outlet is arranged corresponding to the internal space of the fish tank to guide the filtered water into the fish tank. The drainage and waterproofing achieved by this water outlet method is that the filtered water in the device flows directly back into the fish tank from the water outlet, and the filtered water flows from a high place to the water surface of the fish tank to form an impact, thereby generating noise, which cannot meet the silent needs of consumers. Adding drainage pipes to connect the water outlet will increase the number of parts and increase costs, which is not practical. For this reason, the water discharge structure of the existing filter needs to be further improved. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a wall flow drainage structure that does not require drainage pipes and can be attached to the cylinder wall to achieve silent drainage.

[0005] A wall flow water discharge structure of a filter designed for this purpose comprises a filter seat for mounting a filter box assembly;

[0006] The filter seat is provided with a drainage cavity and a drainage port which are interconnected, the drainage cavity is interconnected with the filter box assembly, and the drainage port is used to output the water in the drainage cavity to an external fish tank;

[0007] The drain port is arranged on the wall surface where the filter seat and the fish tank are in contact;

[0008] A water discharge gap is provided between the wall surface of the filter seat facing the fish tank and the tank wall of the fish tank;

[0009] The water outputted from the drain port flows downward along the wall of the fish tank through the water discharge gap.

[0010] Preferably, drainage connection seats are provided on the left and right sides of the filter seat, the interior of the filter seat is connected with the interior of the drainage connection seat, and the drain outlet is provided on the wall surface where the drainage connection seat and the fish tank are in contact.

[0011] Preferably, the wall surface of the filter seat that fits the fish tank is a slope, and the slope is gradually inclined from left to right.

The drainage method implemented by the utility model is that the water output from the drainage port flows downward along the tank wall of the fish tank through the water discharge gap. The effect of this step is that there is no need for drainage pipe fittings to discharge the water, and when the water flows out of the drainage port, the water flows downward along the tank wall. This drainage method can avoid the water output from the drainage port from directly impacting the water surface of the fish tank, thereby reducing the generation of noise.
