Abstract

PURPOSE: A two-step water filter embedding elvan bed and activated carbon bed therein is provided to eliminate harmful components such as heavy metal, contaminant, harmful bacteria, odor, colors and chlorine without the using of high cost of purification system. CONSTITUTION: First, a tap water inlet(10) is connected with tap to receive serve water. After introduction into this two step water filter, tap water including impurities is primarily filtrated through an elvan bed(20) with a thickness of about 10 mm. In the course of the primary purification, especially the characteristics of tap water is changed to mild to drink by far-infrared rays emitted from elvan. Subsequently, tap water is admitted to flow into an activated carbon bed(30) passing through an intermediate partition(40) for secondary filtration.

Description

Two-stage water filter {two step clean water filter}

The present invention relates to a two-stage water filter, and more particularly, to a water purification system that can be used to purify tap water at low cost utilizing only the important advantages of its function.

In general, the water purification system is used as a device for removing the impurities and harmful substances in the water and drinking. In addition, our country is very interested in water, and now our country's tap water is a suitable standard for people to drink.

On the other hand, the water purification system generally used is a waste of water due to the excessive water purification method, in particular, due to the excess water purification system more than necessary has caused a contradiction to use a high cost water purification system.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a cheap and reliable water filter by selecting only essential functions required for actual water purification.

1 is a perspective view showing a system diagram of a two-stage water filter according to the present invention.

50: purified water outlet

In order to achieve the above object, the two-stage water purification filter of the present invention forms a case 10 that can be connected to tap water, and has an interlayer partition 40 having an elvan rock particle layer 20 and an activated carbon particle layer 30 of about 1 mm therein. It is preferable to form with the gap therebetween. In addition, it is preferable to form the purified water outlet 50 so that the purified water can be discharged in the lower portion.

EXAMPLE

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a system diagram showing a two-stage water filter according to the present invention.

First, the tap water inlet 10 is connected to the tap water. When the tap water is introduced to the tap water is filtered first by the elvan rock particle layer 20 of about 1 mm. This process is a precipitation filtration method that filters the heavy metals and other impurities in the tap water by the coarse and wide surface area of elvan. Particularly, the properties of water are changed to a good property for drinking by far-infrared radiation. Thereafter, water is introduced into the activated carbon particle layer 30 through the interlayer partition wall 40 to perform secondary filtration. This process is an adsorption filtration method to remove harmful bacteria, odors, turbidity, chlorine, etc. in the water by adsorption and sterilization of the activated carbon particle layer 30.

Since the purified water is discharged through the purified water outlet 50, it is possible to drink good purified water for drinking.

As described above, according to the present invention, the drinking water without heavy metals, impurities, harmful bacteria, odors, turbidity, chlorine system, etc. is removed using a low-cost two-stage water filter without using an expensive water purification system when drinking tap water. It can be effective.

Claims (2)

As a water filter, the two-stage water filter characterized in that the ganban stone particle layer 20 and the activated carbon particle layer 30 is formed The two-stage water filter according to claim 1, wherein an interlayer partition wall (40) is formed between the elvan particle layer (20) and the activated carbon particle layer (30).
