Aquarium Filter

摘要

A media reactor aquarium filter incorporates a simple design and allows simple media replacement. The filter includes co-axial inner and outer tubes. The outer tube includes a mounting feature and the inner tube holds the media and is removable without disturbing the outer tube. A pump at the base of the filter pumps water into the inner tube through ports at the base of the inner tube and up through the inner tube, and thus through the media. The filtered water then flows through the top wall of the inner tube and down between the inner and outer tubes, and back into the aquarium. The inner tube is rotatable to vary the alignment of the ports to adjust the water flow rate through the filter.

1. An aquarium filter comprising:
an aquarium filter bottom; an aquarium filter top opposite to the aquarium filter bottom; an elongated outer tube having:
an outer tube bottom end proximal to the aquarium filter bottom;an outer tube top end proximal to the aquarium filter top and opposite to the outer tube bottom end;an outer tube interior; andan outer tube exterior; an elongated inner tube residing inside the outer tube and having:
an inner tube bottom end adjacent to the outer tube bottom end;an inner tube top end opposite to the inner tube bottom end and adjacent to the outer tube top end;an inner tube exterior; andan inner tube interior; a filter pump residing proximal to the aquarium filter bottom, the filter pump including an aquarium water inlet placing aquarium water, outside the aquarium filter and proximal to the aquarium filter bottom, in fluid communication with the filter pump; an inlet path residing at the bottom of the aquarium filter placing the filter pump in fluid communication with the inner tube interior at the inner tube bottom end; transfer ports, between the inner tube interior at the inner tube top end and the outer tube interior at the outer tube top end, placing the inner tube interior in fluid communication with the outer tube interior; filter media residing in the inner tube interior between the inlet ports and the transfer ports; a continuous passage between the outer tube interior and the inner tube exterior, the passage reaching from the transfer ports to the outer tube bottom end and placing the transfer ports in fluid communication the outer tube interior at the outer tube bottom end; outlet ports at the bottom of the aquarium filter in fluid communication with the passage placing the passage in fluid communication with the aquarium, and a forward aquarium filter flow sequentially through the pump to the inlet ports, through the inlet ports and into the inner tube interior, up through the inner tube and filter media to the transfer ports, out through the transfer ports to the passage, down through the passage to the bottom of the filter, and out through the outlet ports into the aquarium.
