Water purification system and filtration block
A water purification system for an ornamental aquarium is easily assembled as either a canister or a hang-on-back type model with a water tank or aquarium without compromising with an aesthetic appearance and low noise. The filtration element includes filtration blocks connectible in series for function and can be disassembled into a plurality of blocks that are reassembled to form the canister model and the hang-on-back model with a secure positioning feature.
1. A water purification system, that purifies water-to-be-cleaned by filtration, comprising:
a filtration element comprising at least two filtration blocks connected to each other in a water-flow series;
each of said filtration blocks comprising:
a filtration main unit that has a housing that includes a plurality of cylindrical housing elements arrayed in a side-to-side series along respective parallel long axes thereof from a first narrow side to a second narrow side;
a first side cover having a planar outer surface and an inner surface having a series of respective concave arcs shaped to supportingly receive respective said cylindrical housing elements on a first cover-side;
a second side cover having a planar outer surface and an inner surface having a series of respective concave arcs shaped to supportingly receive respective said cylindrical housing elements on a second cover-side;
each said cylindrical housing element having a top portion with an opening and a removable lid and a bottom portion;
a convex portion extending from said top portion of each said cylindrical housing element away from said cylindrical housing elements perpendicularly to said respective long axes;
a convex element between the bottom portions of one of a pair of said cylindrical housing elements engaging with one of said bottom portions of said first side cover and said second side cover;
a top-cover that entirely covers a top of said filtration main unit and each said removable lid, wherein
said top-cover covers said convex portion extending from said top portions of each said cylindrical housing element;
each said cylindrical housing element receiving a removable filtration material member that is flow connected so that are connected in said water-flow-series between a first upper side opening on said first narrow side and a second upper side opening on said second narrow side;
each of said first and said second upper side openings positioned distal said top-cover on opposing sides thereof;
a through hole in at least one of said convex portions extending through said top portion of one of said respective cylindrical housing elements;
a groove in said top-cover proximate said through hole; and
a fixing element extending from said one top portion through said through hole in said at least one convex portion and along said groove in said top-cover operative to fix said water purification system to an aquarium.
2. The water purification system, according to claim 1 , wherein:
a first of said at least two filtration blocks is joined in said-water-flow series to a second of said at least two filtration blocks at respective ones of said upper side openings along proximate said ones of said first and second narrow sides.
3. The water purification system, according to claim 1 , further comprising:
at least one connection plate between said at least two filtration blocks;
at least one vibration dampener mounted to said at least one connection plate; and
wherein each of said at least one connection plate respectively connects and fixes said filtration blocks and said at least one vibration dampener dampens a vibration therebetween.
