The present invention locks the raw water by automatically closing the flow path by an auto shut off valve or a solenoid valve according to the pressure of the purified water generated in the water purification system using a reverse osmosis filter cartridge or the like. The operation of locking the valve is unnecessary, and the present invention relates to a water filter and a water purification system using the same, which are easily replaced using a connector.

1 is a water flow diagram of a filter having a niphorn type inflow and outflow water, as shown in FIG. 1 as a mechanical type, a general water purification system using a reverse osmosis membrane filter cartridge is connected to a faucet (not shown) through a hose. Sediment filter cartridge and coal minerals to remove macro-sized foreign substances from rust, soil, sand and suspended solids contained in incoming raw water (tap water, groundwater, etc.) Pre-carbon filter cartridge and polyamide composite membrane to remove chlorine components (trihalmethane, etc.) and organic chemicals remaining in water by adsorption method of activated carbon made by burning palm tree at high temperature Reverse osmosis membrane filter (m) to purify various pollutants, bacteria, inorganic substances, heavy metals, etc. in water through fine pores of 0.0001 micron size It includes an embrane filter, or reverse somosis filter (RO) cartridge, and a post-carbon filter cartridge that improves the taste of water by purifying foreign substances such as odors and gaseous components in water. Impurities (concentrated water) filtered by the above-described reverse osmosis membrane filter are discharged to the outside through a flow restrictor.

The auto shutoff valve is generally mounted at the rear of the sediment filter cartridge and uses the Pascal principle to block the flow of raw water (inflow) when the water pressure reaches the set pressure. A flow restrictor is installed to regulate the flow rate of the concentrated water to maintain the concentrated water and purified water discharged through the reverse osmosis filter cartridge at an ideal ratio of 4: 1.

The check valve is provided to prevent the purified water from flowing back by the pressure of the pressure tank when the pressure on the purified water side reaches the set pressure and the raw water is blocked by the auto shutoff valve. In the case of the reverse osmosis membrane filter cartridge, since the production volume of the purified water is very small, the purified water is stored using a pressure tank, and then the high flow rate is discharged at the accumulated pressure during use. In general, the pressure tank is installed in front of the post carbon filter cartridge, the final filter cartridge, so that the purified water stored in the pressure tank finally passes through the post carbon filter cartridge to remove the smell of rubber.

FIG. 2 is a water flow diagram of a water purification system equipped with a filter cartridge having a niphorn type inflow and outflow similar to that shown in FIG. The electronic type water purification system uses the auto shutoff valve configured in the mechanical type to cut off the raw water inflow by using a high press switch (HPS) and a solenoid valve. Except for the configuration, all configurations correspond to the mechanical type. In other words, when the pressure of the purified water reaches a constant pressure, the pressure switch for detecting the pressure of the purified water blocks the electric signal on the solenoid valve side to close the valve to block the inflow of raw water.
