The following specification particularly describes the nature of the invention and the manner in which it is to be performed : -


AN IMPROVED WATER FILTER
The invention relates an improved water filter for the purification of drinking water. More particularly the invention relates to an improved water filter for removing physical impurities as well as micro biological impurities for prevention cf water bone diseases.
The conventional water filter for purification of drinking water ■or removal of physical impurities are known.
In toe conventional water filter the stainless steel container tre fitted with brass, thin plate inside therefore during the course of user these brass plates are dislodged and rusting Itarted which becomes improper and growth of microbeal contr-oination starts & the efficiency of filtering is reduced and herefore unfiltered water are preculated through the outlet (tap
In tne water filter having double container one above the other EO as to receive unfiltered water in the top stainless steel container fitted with ceramic cartridge for purification of physical impurities and at the bottom of the cartridge is fitted with iodine resin cup for microbiological purification and silver impregnated activated carbon cup of chemical purification. The upper container is placed on a (hollow) bracket position above the lower container which collects filtered water and drain throt.gh the tap provided at the? bottom. During long use the brass plate fitted inside the container give away and therefore the cont mated water starts coming which is detrimental for public tealth.


The inventors therefore thoughts of improving upon the existing devices by providing a copper coating through electroplating process inside the stainless steel container thereby avoiding the possible chances of contimination of filtered water.
The principal object of the invention is therefore to provide an pure copper coating through electroplating process inside stainless steel container.
The another object of this inventionis to provide a pure drinking water though the water filtered having copper coating inside the stainless steel contianer so as to avoid further contimination of filtered water.
Accordingly there is provided an improved water filter (1) having a stainless steel upper container (2) which is copper coated through the electro plating process inside; said upper copper coated stainless steel plate (2) is fitted at the base to the high grade ceramic cartridge (3) for purification of physical impurities; the said ceramic cartridge at its base is fitted with iodine resin cup for microbiological purification and silver impregnated activated carbon cup (5) for chemical purification (bacteria, gems) which are placed in an inverted position on the bottom stainless steel cover coated with copper through electroplating process inside for collecting filtered water & having an outlet (tap) (6) for the dispensing filter water; the upper plate containing unfiltered water is position on the lower stainless steel plate through a hollow bracket (7) ; the said upper stainless steel contianer is provided with lid (8).


The .invention will now be described through figure 1 to 5 in the accompanying drawings ;
Referring to figure .1 s is the perspective view of an improved
Water filter.
Referring to figure 2 ; is the sectional view of the an improved
water filter showing the arrangement of ceramic cartridge, iodine resin cup & silver impregnated carbon cup.
Referring to figure 3 ; is the elevation and plan view of the
lid.
Referring to figure 4 : is the sectional view of the ceramics
cartridge and resin cup.
Referring to figure 5 : is the side view of the lower stainless
steel container coated with coppc-?r through electro plating process all the inner side.
Referring to figure 1 to 5 an .Improved Water Filter (1) having .> stainless steel upper container (2) which is copper coated through the electro plating process inside:; said upper copper coated stainless steel plate (2) is fitted at the base to the high grade ceramic cartridge (3) for purification of physical impuritiesj the said ceramic cartridge at its base is fitted with iodir.e resin cup for microbiological purification and silver .impregnated activated carbon cup (5) for chemical purification (bacteria, gems) which are placed in an inverted position on the


bottrm stainless steel cover coated with copper through electroplating process inside for collecting filtered water & having an outlet (tap) {h) for the dispensing filter water; the uoper plate containing unfiltered water is position on the lower stainless steel plate through a hollow bracket (7); the said uoper stainless steel contianer is provided with lid The embodiment shown & described may be of one type several type c. f size and shape will also be covered in the inventive features of coating inside of the container by pure copper through the electro plating process so as to eliminate any contimination of filter water.
This is an embodiment, of the invention. Several modifications are possible may be considered within the ambit and spirit of this invention. Since many modifications, variations and changes in detail may foe made to the above described embodiments, it is intended that all matters described in the foregoing description as described in the accompanying specification.

I Claim :
1. An improved water filter (1) having a stainless steel upper container (2) which is copper coated through the electro plating process inside; said upper copper coated stainless steel plate (2) is fitted at the base to the high grade ceramic cartridge (3) for purification of physical impurities; the said ceramic cartridge at its base is fitted with iodine resin cup for microbiological purification and silver impregnated activated carbon cup (5) for chemical purification (bacteria,) which are placed in an invert ed position on the bottom stainless steel cover coated with copper through electroplating process inside for collec ting filtered wat^r & having an outlet (tap) (6) for the dispensing filter water; the upper plate containing unf iltered water is position on the lower stainless steel pi ate through a hollow bracket (7) ; the said upper stainless steel contianer is provided with lid (8).
2. An improved water filter as claimed in claim 1 wherein the container is coated 'by pure copper through electroplating process.
3. An improved water filter as claimed in claim 1 substantially herein describe with reference to figure 1 to 5 in the accompanying drawing.
