PREMABLE TO THE DESCRIPTION
The following specification particularly describes the nature of the invention and the manner in which it is to be performed.

DOUBLE FILTER INLET VALVE

Field of the Invention
The present invention relates to water treatment devices, and more particularly to devices incorporating mechanisms for end-of-life indication, automatic shutoff, resetting the automatic shutoff and bypass, and to a filter cartridge for water treatment devices.
Background of the Invention
Water treatment devices for home and other use are well known in the art. Such devices are incorporated into a water system either in-line or at a terminal end. An example of the former would be an under-the-counter device which filters water prior to reaching the faucet. There are two common types of terminal end devices--countertop and faucet-mounted. As compared to countertop and under-the-sink devices, designing a faucet-mounted device presents special challenges. These include making the device sufficiently light so that it can be attached to a faucet and sufficiently compact so that the device does not take up valuable sink space.

Water treatment devices can treat water by the use of mechanical filtration or chemical treatment.

Mechanical filters treat water by preventing passage of particulates. As a mechanical filter approaches the end of its useful life, reduced or stopped flow due to particulate accumulation provides a ready indication that element replacement is necessary. By contrast, when the capacity of a chemical element is exceeded, there is no such indication. Chemical treatment is accomplished by processes such as adsorption (e.g. charcoal media) and ion exchange (e.g. for lead removal) . Such chemical treatment eventually degrades and becomes inactive. However, no indication is provided to the user that the water is no longer being treated by the media. As a result, various approaches have been taken to indicate end of life to the user where it is not inherently provided by the behavior of the filter media.

One example is shown in U.S. Patent No. 4,686,037. In this approach, a pre-filter is used to entrap contaminants, and the color of the pre-filter is compared by the user with a reference strip to determine when the media requires replacement . The problem with this approach, however, is that it is inherently subjective, and therefore subject to error. Also, the user can easily forget to check the reference filter and mistakenly believe the media is still purifying when it is not.

A much more accurate and foolproof means of indicating end of life is through totalizing the volume which has passed through the media and automatically shutting off flow after a predetermined volume has passed through the device. Although the flow totalization and shutoff valve mechanisms required are relatively expensive and complex, this has become recognized as the most accurate means of indicating end of life.

However, prior art mechanical automatic shutoff mechanisms suffer from certain shortcomings.
A feature that is common to faucet-mounted devices is the ability to bypass or divert water from the filter media so that untreated water can be obtained from the faucet. This is desirable because it avoids unnecessary use of the filter media, allowing the user to bypass the water treatment device if the water is not intended for drinking, as for example for washing hands or dishes.
Such a bypass mechanism is shown in the some patent. In this approach, a separate handle is attached to the opposite end of the mounting member to control a bypass valve. Other prior art devices use this same approach, and therefore suffer from certain disadvantages. The separate handle adds unnecessary complexity and expense to manufacturing a bypass mechanism. Also, because of the environment in which faucet-mounted devices are employed, there is a significant problem with keeping such devices clean. A separate handle only makes this more difficult, adding increased surface area and creating difficult-to-clean crevices. Finally, the added handle makes the appearance of the device less appealing, which is a particularly important concern for faucet-mounted devices.
What has been needed is a compact, low-cost and easy-to-manufacture water treatment device having an automatic shutoff mechanism which is easy to reset. What has also been needed is a faucet-mounted device incorporating automatic shutoff and a simple bypass mechanism. What has also been needed is a replacement filter cartridge which can reset the flow totalization and shut- off mechanism upon replacement of the cartridge and which provides a simple water flow path and efficient sealing in communication with the water treatment device.

Object of the Invention

In the present invention double filter system , wherein first filter is having high density stainless steel mesh filter and the entire filter is covered with filter cloth so, first the filtration is done at the filter cloths , which will increase the life of the Internal filter and also making the cleaning process more efficient. The outer filter cloths are replaced easily at regular interval which also increase the cost effective.

Summary of the Invention According to the present invention, a water treatment device having a replaceable filter clothe is provided. The filter cartridge can include mechanical filter cloths and high density stainless steel mesh filter system.

It should be understood that the present invention is not limited to the preferred embodiment discussed above, which is illustrative only. Changes may be made in detail, especially matters of shape, size, arrangement of parts, or material of components within the principles of the invention to the full extent indicated by the broad general meanings of the terms in which the appended claims are expressed.

BRIEF DESCRIPTION OF THE DRAWINGS
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings,
Fig. 1 represents the block diagram of the present invented device

Detailed description of the invention
Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of the construction and arrangement of parts illustrated in the accompanying drawings. The invention is capable of other embodiments, as depicted in different figures as described above and of being practiced or carried out in a variety of ways. It is to be understood that the phraseology and terminology employed herein is for the purpose of description and not of limitation.

As shown in Fig.1 , represents the block diagram of present invented device , wherein the double filter inlet valve is consists with dual filter system, wherein one filter is provided centrally with high grade stainless steel mash filter , which is covered with easily replaceable cotton fabric filter clothe, that entirely cover the central filter so, when the water or any liquid consents enter though the inlet valve filter system, an outer filter cloths first filter and then inner central filter clean the liquid content ,the outer filter is required to replace after some time which can easily replaceable. To replace the outer filter , the filter device is required to bring out by opening the upper or lower circular valve opening and bring out the filer device and easily replace the outer filter clothes and also clean the inner filter if required at regular interval.
Due to the use of outer filter clothes, inner filter life is become longer and that also prevents the valve jam due to dust block the filter system.

While, the invention has been described with respect to the given embodiment, it will be appreciated that many variations, modifications and other applications of the invention may be made. However, it is to be expressly understood that such modifications and adaptations are within the scope of the present invention, as set forth in the following claims.
