Abstract:
1. A device for purifying water disposed within a sink comprising: a base having a bottom surface and a top surface, wherein the bottom surface of the base is adapted to be positioned on the bottom of the sink; a plurality of hanging rings disposed on the top surface of the base; a water collector for collecting filtrate or receiving a backwashing fluid, wherein the water collector includes a bottom surface that is fixed on the top surface of the base, and an upper lip rendered on a top of the water collector, wherein the upper lip defines an upwardly facing surface; at least one water connection provided on a vertical outer peripheral surface of the water collector for flowing the filtrate out of the collector or receiving a backwashing fluid into the collector, wherein the water connection is to be connected to a pump; a plurality of basket assemblies each said basket assembly having a top and a bottom, and each basket assembly being provided with a mesh screen at the bottom of the basket assembly for carrying filter agent or adsorbent; a quantity of filter agent or absorbent disposed on the mesh screen of each said basket assembly; a plurality of spacers that are separable from the basket assemblies, wherein each one of said spacers fixes the top of one of the basket assemblies to the bottom of an adjacent one of the basket assemblies, and wherein each said spacer includes an upwardly facing surface and a downwardly facing surface; wherein the bottom of a lowermost one of the plurality of basket assemblies is received within the upper lip of the water collector; a plurality of sealing washers, wherein one of said sealing washers is mounted between the upwardly facing surface of the upper lip of the water collector and the bottom of the lowermost one of the plurality of basket assemblies, and wherein one of said seals is mounted between the top of each of the basket assemblies and the downwardly facing surface of each of the spacers, and wherein one of the seals is mounted between the bottom of each of the basket assemblies and the upwardly facing surface of each of the spacers; a plurality of fixing rings disposed on an outer vertical peripheral surface of each of the spacers, wherein the fixing rings of each of the spacers are vertically aligned with the fixing rings of the other spacers; and a plurality of holding rods fixed on an outer vertical peripheral surface of the water collector, wherein each of the holding rods is inserted vertically through the vertically aligned fixing rings of the spacers.
