Technical Field

[0001] The utility model relates to the technical field of fish tank water purification equipment, in particular to a cleaning filter for a fish tank for cultivating ornamental fish. Background Art

[0002] The amount of food intake and excretion of ornamental fish during their growth is very large, so a large amount of metabolic waste is produced during the metabolism process. Among them, ammonia and nitrite are metabolites that are toxic to fish. Together with the leftover bait, we must remove them before they become toxic substances to ensure the life safety of the fish in the fish tank. The fish tank filter is an important device for keeping the water clean and stable. Its working principle is based on three aspects: physics, chemistry and biology. The fish tank filter usually includes a combination of these three filtering methods to ensure the comprehensive purification and stability of the water quality. When the water flows through the filter, it first passes through the physical filter layer to remove large particles of impurities, then enters the chemical filter layer to remove organic matter and odor, and finally passes through the biological filter layer to decompose organic waste and convert ammonia nitrogen.

[0003] The structures in the prior art are relatively complex and large in size. The single filter component leads to poor filtering effect and low filtering efficiency. It is also difficult to clean the inside of the filter in a timely manner, which leads to the problem that the internal filtering structure is easily blocked. Utility Model Content

The connection method is simple and convenient to disassemble for cleaning. Water is sucked into the cylinder by a submersible pump, so that impurities around the bottom of the filter are sucked together. The first filtration is carried out through the notch on the support seat and the first filter plate to prevent the impurities from being too large to block the filter. Then the impurities are controlled by the limiting block to control the amount of impurities. Then, the second filtration is carried out through the filter frame. The lighter impurities are adsorbed outside the filter frame.
