Description

Water filter and its manufacturing method {WATER FILTE AND METHOD FOR MANUFACTURING THEREOF}

The present invention relates to a water purification filter and a method of manufacturing the same, and more particularly, to provide the adsorption function and the particle removal function of various contaminants present in the water at the same time, by improving the filter structure of the multiple system of the water purifier as a composite single filter The present invention relates to a water filter and a manufacturing method for performing the adsorption function and the particle removal function.

Among the various pollution and environmental problems that inevitably occur with the advancement of the industry, the most serious problem is pollution of water supply.

Water pollution is caused by various wastewater and household sewage discharged from factories and livestock farms.As the quality of the water supply itself decreases, the aging of the water supply and tap water supply pipes and the increase of collective housing facilities such as apartments are supplied to each household. It has been the cause of further deterioration of the quality of tap water.

In recent years, the tap water supplied from each home or office is rarely drinked as it is, and natural water is purchased and used as drinking water or various types of water purifiers are used to purify the tap water and then use it as drinking water.

Generally, a water purifier is a device used as a mechanism for purifying water, and a plurality of filter cases for water purification are built in therein. Such a plurality of water purifier filter cases are generally formed in a cylindrical shape of a predetermined length, and the filters (not shown) for various purposes such as impurities removal and odor removal are housed therein and are sealed except the inlet and the outlet. Accordingly, the natural water such as tap water passing through the water purifier filter case not only filters impurities and removes odors while passing through the filters for the various applications.

The water purifier filter case in which the filter used in this manner is stored for a certain period of time, so that impurities contained in water passing through the filter in the water purifier filter case are loaded into the filter, and thus the water purifier filter does not perform the water purification function. . Accordingly, after a predetermined time of use, the water purifier filter, that is, the water purifier filter case should be replaced.

As shown in FIG. 1, a support apparatus of a conventional water purifier filter case performing such a function includes a plurality of filter cases, that is, a first filter case 11, a second filter case 12, and a third filter case 13. ) And the fourth filter case 14 are mounted in parallel on the support plate 20, and the filter cases 11, 12, 13 are provided by a plurality of annular clips 30 attached to the support plate 20. 14 is supported on the outer circumferential surface, the inlet pipe 41 is connected on one end of each of the plurality of filter cases (11, 12, 13, 14) and the outlet pipe (51) on the other end, respectively, Auxiliary inlet pipe 42 and the inlet pipe 41 respectively attached on one end of the filter case are fastened by the first nut 43, and are respectively attached on the other end of the filter case. The auxiliary outlet pipe 52 and the outlet pipe 51 which are present is fastened by the second nut 53 is configured.

In the conventional water purifier filter support device configured as described above, a plurality of filter cases 11, 12, 13, and 14 are arranged and used in parallel in a state in which each of the filter cases 11, 12, 13, 14 is supported by the annular clip 30 on the support plate 20.

In this state, the water to be purified is introduced through the inlet pipe 41 connected to one end of the first filter case 11, and the water passing through the inlet pipe 41 passes through the auxiliary inlet pipe 42. Through the first filter case 11 is introduced into. Water flowing into the first filter case 11 is purified by a filter housed while passing through the inside of the filter case.

In general, the water passing through the first filter case 11 is filtered by the filter, such as green water, debris and suspended matter contained in itself.

Water passing through the first filter case 11 flows out through the auxiliary outlet pipe 52 attached to the other end, passes through the outlet pipe 51, and then flows into the second filter case 12.

In this way, the water passing through the first filter case 11 is purified while continuously passing through the series of the second filter case 12, the third filter case 13, and the fourth filter case 14. In general, the water passing through the second to fourth filter cases not only removes impure taste or smell contained in itself, but also removes residual chlorine components and the like.

In this way, various filter cartridges in which activated carbon, ion exchange resin, or activated carbon and a polymer membrane filter are combined in a water purifier are used as a filter for removing various contaminants.

However, the conventional water purifier filter as described above is composed of a plurality of materials and the installation cost increases, there is a problem that the installation and replacement work is inconvenient.

In addition, since the use of an adhesive material such as a binder in the filter, there is a problem that the filtering efficiency is lowered and may adversely affect the human body.

In addition, the case is opaque, there was also a problem that can not visually check the replacement time of the filter.

Accordingly, the present invention has been made to solve the above problems, and at the same time provide the adsorption function and the particle removal function of the various contaminants present in the water, improve the filter structure of the multiple system of the water purifier composed of a composite single filter It is an object of the present invention to provide a water purification filter and a manufacturing method for performing the adsorption function and particle removal function.
