The filter element of the US 977 patent may have a filter media, such as non-soluble calcium sulphite, alone or combined with a copper-zinc medium therein.
Another example of shower water filter is disclosed in the U.S. Pat. No. 6,537,455 (US 455 patent) entitled “Elongated Hand-held Shower Head and Filter” having a grant date of 25 Mar. 2003 (Applicant: David K. Farley) disclosed a combination of hand held shower head and water filter assembly for filtering contaminants from hot water passing there through at high flow rates. It is further provided in the US 455 patent to provide an improved elongated combination hand held shower head and water filter having a swivel shower head attached to an elongated in line hose filter that is sized and dimensioned to it into a holding bracket in two positions.
A further example of shower water filter is disclosed in the U.S. Pat. No. 6,096,197 (US 197 patent) entitled “Shower Filter For Chlorine Removal and Scale Deposit Prevention” having a filing date of 11 Dec. 1997 (Applicant: Douglas E. Hughes) disclosed dual-purpose shower and bath filter to reduce chlorine in shower water through absorption, reduce or eliminate scale deposits. The filter unit enables a single device to simultaneously prevent scale deposits from forming on plumbing and wall surfaces while also reducing or eliminating the chlorine from shower spray. It is further disclosed in US 197 patent that the filter cartridge accomplishes the scale reduction or prevention by treating water with a specially designed phosphate that coats scale (comprising calcium and magnesium) so that it will not stick to plumbing or wall surfaces. Further, the filter cartridge accomplishes the reduction or elimination of chlorine in the water through the absorption capabilities of a superfine mesh powdered activated carbon, formed into a carbon block.
It is the general object of the invention to provide an improved water shower filter unit that effectively removes chlorine, organic contaminants end suspended solid from shower water through multi-layer filter which can further enhance the water quality during bathing and showering.

The present invention consists of features and a combination of parts hereinafter fully described and illustrated in the accompanying drawings, it being understood that various changes in the details may be made without departing from the scope of the invention or sacrificing any of the advantages of the present invention.
To further clarify various aspects of some embodiments of the present invention, a more particular description of the invention will be rendered by references to specific embodiments thereof, which are illustrated in the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope. The invention will be described and explained with additional specificity and detail through the accompanying drawings.
The present invention relates to a bath shower unit with disposable filtration unit. Hereinafter, this specification will describe the present invention according to the preferred embodiments. It is to be understood that limiting the description to the preferred embodiments of the invention is merely to facilitate discussion of the present invention and it is envisioned without departing from the scope of the appended claims.
Referring to
The housing (104) having top cover (102) and interior space for enclosing, a storage tank (108) and directing flow through filtration unit.
The shower head (120) may be constructed in any conventional or known manner from any acceptable material, such as a high strength plastic or the like. The shower head (120) having hollow filter handle with elongated, internal chamber where the tertiary filter (116) held therein. The first end of a flexible hose (152, 154, 156) connected to the shower head and the second end to the storage tank (108)
A water inlet and a water outlet are connected to the water storage tank (108) through a coupling member (122). The water inlet is to let unfiltered water enter the system to receive treatment. The water outlet is for draining the filtered water through the flexible shower hose (108) attached to the shower head (120).
The first stage of filtration is the primary filter (112). The primary filter (112) constructed from polymer type material like Filtron™ high density fabric as the filtration medium (143) which attached to filter holder (111). This fabric is preferred due to its ability to filter off particles size of 10 microns and above. Other filtration medium that can achieve this can also be used instead.
The second stage of filtration is the secondary filter. The secondary filter (114) comprises of multiple layer of activated balls (145, 147) divided by spacer (130) and held filter cartridge (140). The filter cartridge (140) has the end cap (132) and the other end having threaded end. Thus, the filter cartridge (140) may be installed with threaded end in downward position and the end cap (132) in upward position.
The third stage of filtration is the tertiary filter. The tertiary filter (116) contains magnetic ceramics balls and mineral stones held in elongated cylindrical filter cartridge which is aligned to be coaxial with longitudinal axis of the shower head (120) filter handle. A dynamic O-ring (115) is seated in annular grooves in the cartridge neck to facilitate water tight seal. Magnetic ceramics balls and mineral stones of the tertiary filter (116) are used to activate the water. Water that undergoes activation treatment by magnetic field or bio-ceramic stones will transform into smaller clusters of water molecules.
In use, when the water flows from the water inlet, it passes through the primary filter (112) for removal of suspended solid, and then through the secondary filter (114) for removal of chlorine and finally passes through tertiary filter (116) to enhance water quality through water activation before exiting through the shower head (120).
The present embodiments are considered as merely illustrative and not restrictive, the description to the preferred embodiments of the invention is merely to facilitate discussion of the present invention and it is envisioned without departing from the scope of the appended claims.
