The utility model integrates a water inlet channel through the box cover element, so that water can enter through the inside of the box cover element and be output to the filter box assembly for filtration. This arrangement can omit the use of the water inlet pipe in the prior art, reduce the number of parts, and facilitate customers to assemble it themselves after purchase. At the same time, reducing the use of the water inlet pipe can improve the space utilization inside the filter box assembly to achieve a small volume.

[0027] See also Figure 4 , Figure 6 and Fig.10 The filter seat 10 is provided with a drainage cavity 120 and a drainage port 110 which are interconnected. The drainage cavity 120 is interconnected with the filter box assembly 20. The drainage port 110 is used to output the water in the drainage cavity 120 to the external fish tank. In the present utility model, the filtered water output by the filter box assembly 20 is transported to the drainage cavity 120, and then output from the drainage cavity 120 to the external fish tank 40 from the drainage port 110.

[0028] See also Figure 3 and Figure 4 The filter box assembly 20 includes a box body 200 disposed on the filter seat 10, the box body 200 is hollow inside and has an upper opening, the box cover element 30 is covered on the box body 200, a filter box 211 and an overflow box 212 are disposed in the box body 200, the filter box 211 and the overflow box 212 are longitudinally spaced, the filter box 211 and the overflow box 212 are connected to each other, the upper opening of the filter box 211 is used to receive water discharged from the box cover element 30, and the upper opening of the overflow box 212 is used to receive water discharged from the filter box 211;

[0029] A water channel 220 is provided between the overflow box 212 and the box body 200 , a water outlet 230 connected to the filter seat 10 is provided at the bottom of the water channel 220 , and an overflow port 214 is provided on the overflow box 212 , and the overflow port 214 is connected to the water channel 220 .
