Frozen Food Aquarium Feeder

摘要

A frozen food aquarium feeder controls the melting and dispersion of frozen aquarium food. The feeder includes a rotatable first cylindrical column having a floor/ceiling including a set of passages and a rotatable second cylindrical column having a ceiling/floor including a matching set of passages. The cylindrical columns are assembled with an interference fit to a round bracket allowing each cylindrical column to be rotated with respect to the round bracket. The floor/ceiling of the first cylindrical column may reside against the ceiling/floor of the lower column, and the cylindrical columns may be positioned to provide a desired overlap between the passages to control the passage of melted food from the first cylindrical column to the second cylindrical column. The feeder may be positioned with the first cylindrical column extending above the aquarium water line, and ports in walls of the cylindrical columns may be positioned to intercept aquarium currents.

主权项

1. A frozen fish food feeder, comprising:
a first cylindrical column including:
a first vertical centerline CL1;a floor;first ports in a first wall of the first cylindrical column; andfirst passages in the floor; a second cylindrical column coupled to the first cylindrical column including:
a second vertical centerline CL2;a ceiling;second ports in a second wall of the second cylindrical column; andsecond passages in the ceiling, wherein:
the first and second cylindrical columns are rotatable about the first and second centerlines Cl1 and CL2 and the first passages are variably alignable with the second passages to vary openings between the first cylindrical column and the second cylindrical column and the first and second ports are adjustable with respect to currents in an aquarium.
