发明名称 Inside filter for aquariums
摘要 A bottom aquarium filter for an aquarium tank including a substantially cylindrical container having an inwardly directed concave forward wall. A grill wall removably coupled onto the concave forward wall and defining therewith an inlet chamber. A removable L-shaped insert member includes a substantially circular perforated platform wall and an upstanding convex partition wall. The platform wall spacedly sits on the bottom of the container and defines with the container a filtration chamber above the platform and a clear water chamber beneath the platform. The partition wall mates in opposition against a rear peripheral section of the circular wall of the container and defines therewith an air lift chamber. A removable cover mounts onto the container and includes a mouth aligned with the air lift chamber. The cover serves to retain all of the members in unitary assembly. An air tube fits into a spout projecting from the rear peripheral wall and extends into the air lift chamber terminating in an air diffuser which sits in a depressed compartment beneath the base wall of the container. The air tube can serve as a handle for lifting the filter assembly. The assembly can be easily separated for cleaning without the difficulty in reaching any portion of pre-formed compartments.
