Patent ID: 7211188

Claim:
A solar powered aquarium of unitary construction comprising, in combination: a water retaining vessel including a first base plate and a first wall extending upwardly from the first base plate and defining therewith a water retaining vessel interior; a second wall positioned on said first base plate and extending upwardly therefrom into said water vessel retaining interior; a second base plate supported by said second wall and positioned above said first base plate, said second wall being spaced inwardly of said first wall and said second plate defining at least one second plate opening; water flow path defining structure having an upper end and a lower end within the confines of said second wall and spaced therefrom positioned on said first plate and defining a water flow path leading from said at least one second plate opening, said water flow path defining structure defining at least one aperture at said lower end; a rotatable magnetically drivable pump member disposed within said water flow path between said first plate and said second plate adjacent to said at least one aperture; a base supporting said first plate and disposed thereunder; a DC motor disposed within said base; a rotatable structural element attached to said DC motor under said first plate magnetically coupled to said magnetically drivable pump member and rotatable by said DC motor to rotate said magnetically drivable pump member through the magnetic coupling existing between said rotatable structural element and said magnetically drivable pump member, rotation of said magnetically drivable pump member causing the flow of water in said water retaining vessel downwardly from said at least one second plate opening through said water flow path defining structure and outwardly through said at least one aperture at the lower end of said water flow path defining structure and through said second wall to promote entrapment of debris in said water retaining vessel interior in a gravel bed located in said water relating vessel interior; and at least one externally mounted solar panel operatively associated with said DC motor to energize said DC motor.
