Description

TECHNICAL FIELD [0001] The present invention relates to a water purification system having a composite filter,

The present invention relates to a water purification system with a composite filter.

More specifically, the first filter unit and the second filter unit can filter foreign matter such as rust from the raw water and improve the moisturizing amount of purified water. And the like.

In general, contaminated water is difficult to drink or use immediately, so it is used as tap water by disinfection and purification in a water treatment facility. However, since the chlorine component used in the disinfection process is not easily removed but remains dissolved in the water, a specific chlorine odor is generated in the water contamination.

A high residual chlorine level in tap water causes dermatitis and atopic diseases in children and people with weak skin. Even if tap water is boiled, the evaporated chlorine is released into the atmosphere, But also triggers the generation of carcinogens called trihalomethane.

In order to remove chlorine components in tap water, there is known a technique of removing a chlorine component remaining in tap water by providing a water filter and a filter in a shower to be used for drinking water. Especially, In addition to chlorine removal, the water purification device is also used for skin cosmetics by adding aloe, aloe, phalaenopsis, evening primrose oil and olive oil.

As one of the prior arts related thereto, Japanese Patent No. 10-1222813 discloses a complex water filter.

1 is a view showing a conventional composite water filter.

Referring to FIG. 1, a conventional water purifier filter is provided in a water filter housing to filter various impurities contained in tap water, remove chemicals such as chlorine, and particulate heavy metals.

The water purifier according to the present invention comprises an upper water filter 1 having a through hole 1a formed at the center thereof, a connection cap 2 connected to a lower portion of the upper water filter 1, A lower water filter 3 coupled to a lower portion of the lower water filter 3 and having a through hole 3a formed at a center thereof, an intake cap 4 coupled to an upper portion of the upper water filter 1, A ceramic ball or an antibacterial ball is provided in the through holes 1a and 3a of the upper water filter 1 and the lower water filter 3 to purify the water, A magnetic body 6 is provided on the upper and lower portions of the body 2 to magnetize the water.

However, in the above-mentioned prior art, when the water filter is to be replaced in the water filter housing, since the water filter housing is separated from the tap water faucet and the water filter is removed from the water filter housing, There is a troublesome problem.

Since most of the water is supplied in a non-magnetized state by the magnetic body 6 because the magnetic body 6 for magnetizing the water is provided only at the upper and lower portions of the connecting cap 2, ), There is a problem that the elapsed time required for magnetization is insufficient.

The first water channel 33 connected to the first inlet 211 and the second water channel 35 connected to the first outlet 212 are connected to the filter housing 10 by the first filter head 21, And may be made of a flexible material so as to be easily rotatable.

The first filter body 22 includes an adapter 221 including an inlet guide hole 221a connected to the first inlet 211 and an outlet guide hole 221b connected to the first outlet 212, And a dewatering filter 222 formed at a lower portion of the adapter 221 and having a through hole 222a connected to the outlet guide hole 221b.

The supply water supplied from the outside of the filter housing 10 flows through the first inlet 211 of the first filter head 21 and the inlet guide hole 221a of the adapter 221, The water flowing into the first filter body 22 is filtered through the rind removal filter 222 to remove the rust and the filtered water is removed through the filtering process. Out port 221b of the adapter 221 and the first outlet 212 of the first filter head 21 through the hole 222a and is guided by the guide tube 30 to the second filter portion 40).

The second filter unit 40 is provided with a second inlet 411 through which water guided through the guide tube 30 flows and a second outlet 412 formed adjacent to the second inlet 411, A second filter head 41 which is rotatably coupled to the inside of the filter housing 10 and a second filter head 41 which is coupled to the second filter head 41 and which filters the water introduced through the second inlet 411, And a second filter body (42) for discharging the water to the second outlet (412).

A partition wall 421 is formed at the center of the inner surface of the second filter head 41 to divide the upper portion and the central portion of the second filter body 42 into two regions. The introduced water can be guided to pass through the two regions by the partition wall 421.

At this time, the second filter body 42 may include at least one of the moisturizing filter 422, the ceramic filter 423, the aroma filter 424, and the magnet filter 425 as described above. However, The ceramic filter 423, the aroma filter 424, and the magnet filter 425 are all provided to illustrate the smooth operation of the second filter unit 40 according to the embodiment. I will explain.

The humectant filter 422, the ceramic filter 423 and the aroma filter 424 included in the second filter body 42 are connected to the humidifier filter 422 in accordance with the traveling direction of water guided through the guide pipe 30, The ceramic filter 423 and the aroma filter 424 may be arranged in this order and the magnet filter 425 may be formed on the inner side along the longitudinal direction of the second filter body 42 and on the partition wall 421 .

The water can be magnetized by the magnet filter 425 and converted into hexagonal water based on the 'magnetic water number theory'. The term "magnetized water" in the magnetized water theory means "water activated by magnetic force", and the magnetic force is generated by induction of a magnetic field by the magnetic field induction (MHD theory) of Faraday (British physicist) And forms a strong magnetic field inside. According to the Faraday's magnetic fluid dynamics, if a flowing water having an electric current flow across the magnetic field space, an electromotive force acts on the magnetic flux line at a right angle to generate energy, At the same time, many kinds of ions contained in tap water and groundwater are in the water molecule group. Cation (+) is the (-) pole of the magnetic field, ). At this time, the ions collide with each other, bind and dilute, and water is activated. As the water passes through the magnetic field of the magnet, a magnetic wave acts on the anions and cations of the water to convert water molecules, Water that changes the molecular structure of water into hexagonal rings is called 'magnetized hexagonal'.

The water guided through the guide pipe 30 flows into the second filter body 42 through the second inlet 411 of the second filter head 41, 42 are magnetized by the magnet filter 425 to produce a hexagonal water in the course of being filtered in order from the humectant filter 422, the ceramic filter 423 and the aroma filter 424, The filtered water flowing through the ceramic filter 422, the ceramic filter 423, the aroma filter 424 and the magnet filter 425 may flow out through the second outlet 412.

The guide pipe 30 may further include a flow meter for measuring a flow rate of the flow filtered by the first filter unit 20 and guided to the second filter unit 40.
