Abstract:
1. A design method of an against-wall-glass sinking magnetic scrubber assembly based on using the magnetic scrubber assembly for cleaning the wall-glass of an aquarium, comprising an internal scrubbing component and an hand-hold scrubbing component; comprising the steps of: A. providing a set of magnets and magneto-conductive plate that are installed in the said internal scrubbing component, providing another set of magnets and a magneto-conductive plate that are installed in said hand-hold scrubbing component, and whereby the internal scrubbing component on the inner surface of the wall-glass can move with movement of the hand-hold scrubbing component on the outer surface of the wall-glass of the aquarium; B. providing a scrubbing material which is covered on surfaces of the front cover of said internal scrubbing component and of a base shell of said hand-hold scrubbing component; C. arranging a total specific gravity of the internal scrubbing component to be greater than that of liquid contained in the aquarium; D. arranging a center of gravity of the internal scrubbing component to be underneath a geometrically horizontal central axes of the internal scrubbing component; E. wherein a product of a length Lp from a center of gravity Pp of internal scrubbing component to a lowest point and gravity P of the internal scrubbing component is smaller than a product of a length Lf from an equivalent function point Pf of buoyancy F that the internal scrubbing component is exerted to its lowest part and the buoyancy F that the internal scrubbing component is exerted, such that the internal scrubbing component erects automatically after it is lied down.
