Abstract
An automatic feeding apparatus for an aquarium has a housing, a supply drum rotatably supported in the housing and provided with a food discharge opening, a drive device arranged in the housing for driving the supply drum. The housing has an opening which is spaced from the food discharge opening and through which outer air is supplied. The drive device has a blower and operates so that the outer air is supplied into an interior of the housing and then into the supply drum and through the supply drum to the food discharge opening so that when the blower is immovable moist air rising in a region of the supply drum near the food discharge opening produces an underpressure in a region of the food discharge opening so that the outer air is aspirated into the housing, through the supply drum and out the food discharge opening, while when the impeller is actuated outer air is blown by an inner overpressure produced by the blower in the same direction through the supply drum out of the food discharge opening to operate as a blocking air stream.
