Description
Technical Field
[0001] The utility model relates to a filter box, in particular to an anti-overflow filter box and a stacked filter device. Background Art
[0002] A filter box is required to filter the water in the fish tank. Filter cotton or filter material is placed inside the filter box to intercept food residues, feces and other impurities in the water to keep the water clean and clear. Existing filter boxes often overflow due to reasons such as too fast water flow or large water flow or clogging of the filter material. The overflowing water flows back to the fish tank without being filtered, causing water pollution and greatly reducing the filtering effect of the filter box. Due to structural reasons, the existing fish tank filter device has a large water flow noise, and the water flow is uneven when passing through the filter material, which is easy to cause blockage. The number of times the filter material is cleaned increases, and the filtering effect is affected.
[0003] Therefore, it is necessary to solve the above technical problems. Summary of the invention
