Manifold for domestic water purifier system with specific cartridge replacement

A water purification system, comprising:

• a manifold having a top surface and a bottom surface, the top surface having at least one flow path structure disposed thereon, the at least one flow path structure having at least one channel formation, the bottom surface having a receptacle for receiving a filter cartridge, the receptacle having a complementary helical locking thread extending radially thereon, the complementary helical locking thread further having an indentation or aperture;
• at least one valve for allowing or prohibiting a direct flow of water received in the at least one channel formation of the at least one flow path structure on said top surface of the manifold, wherein closing of the at least one valve can further redirect the flow of water from the at least one flow path structure to components other than said at least one filter cartridge;
• and
• the filter cartridge having a threaded, cylindrical structure with a helical thread for mating with the complementary helical locking thread of the receptacle, the cartridge helical thread having a protrusion disposed thereon for reception by the indentation or aperture of the receptacle complementary helical locking thread.

A method of assembling a water purification system, comprising:

• providing a manifold having a top surface and a bottom surface, the top surface having at least one flow path structure disposed thereon, the at least one flow path structure having a channel formation for receiving a valve for allowing or prohibiting a direct flow of water, the bottom surface having at least one receptacle for receiving at least one filter cartridge, the at least one receptacle having a complementary helical locking thread, the complementary helical locking thread having an indentation or aperture disposed thereon, the at least one filter cartridge having a helical thread for mating with the complementary helical locking thread of the at least one receptacle of the manifold, the helical thread further having a protrusion disposed thereon for locking reception by the manifold;
• inserting the at least one filter cartridge into the at least one receptacle of the manifold;
• rotating the at least one filter cartridge within the at least one receptacle such that the helical thread of the at least one filter cartridge traverses through the complementary helical locking thread of the at least one receptacle;
• snapping the protrusion of the cartridge helical thread into the indentation or aperture of the receptacle complementary helical locking thread;
• locking the at least one filter cartridge into the manifold;
• if allowing a direct flow of water, opening the valve in the at least one flow path structure channel formation;
• and
• if redirecting the flow of water to components other than said at least one filter cartridge, closing the valve in the at least one flow path structure channel formation.

A water purification system, comprising:

• a manifold having a top surface and a bottom surface, the top surface having a plurality of flow path structures disposed thereon, the plurality of flow path structures having channel formations, the manifold bottom surface having receptacles for receiving a plurality of filter cartridges, the receptacles having complementary helical locking threads extending radially thereon, the complementary helical locking threads further having indentations or apertures;
• a plurality of valves for allowing or prohibiting a direct flow of water between the plurality of filter cartridges received in the plurality of flow path structure channel formations on said top surface of the manifold, wherein closing of at least one of said plurality of valves can further redirect the flow of water from the plurality of flow path structures to components other than said plurality of filter cartridges;
• and
• the plurality of filter cartridges each having a threaded, cylindrical structure with a helical thread for mating with the complementary helical locking threads of the receptacles, the cartridge helical threads having protrusions disposed thereon for reception by the indentations or apertures of the receptacle complementary helical locking threads.
