Air pump for aquariums

USPTO Application #: 20070237653
Title: Air pump for aquariums
Abstract: An air pump for aquariums to reduce noise and shrink the casing includes at least one air pump assembly in the casing. The air pump assembly has an air delivery duct communicating with a muffling chamber located on an outer bottom side of the base of the casing. Air discharged by the air pump assembly passes through a circuitous path in the muffling chamber. Thus noise can be reduced. The casing also can be shrunk to a smaller size. (end of abstract)
