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. It is unnecessary to lock the operation, and relates to a water purification filter and a water purification system using the same is easily replaced using a connector.

1 shows a water flow diagram of a mechanical type water purification system in a filter having a niphorn type inflow and outflow water, a general water purification system using a reverse osmosis membrane filter cartridge is provided through a hose connected to a faucet (not shown). 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 that purifies various pollutants, bacteria, inorganic substances, heavy metals, etc. in water through fine pores of 0.0001 micron size by The emitter comprising an (membrane filter, or reverse somosis filter (RO)) cartridge and the smell of water, post-carbon filter (post-carbon filter) to improve the water treatment mulmat by the foreign matter such as a gas component cartridge. Impurities (concentrated water) filtered by the reverse osmosis membrane filter cartridge described above are discharged to the outside through a flow restrictor.

The auto shutoff valve is generally installed at the rear of the sediment filter cartridge and uses the principle of Pascal. When the pressure on the purified water reaches a predetermined pressure, the flow of raw water is blocked to prevent the water purification system from failing. do. 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 shows a water flow diagram of an electronic type water purification system in a filter having a niphorn type inflow and outflow water, using a solenoid valve and a pressure switch instead of an auto shutoff valve of a mechanical type water purification system. The solenoid valve is generally mounted at the rear of the sediment filter cartridge. When the pressure of the purified water reaches a certain pressure, the high pressure switch (HPS), which detects the pressure of the purified water, cuts off the electrical signal. It blocks the flow (inflow) of raw water and prevents the water system failure.

In the water purification system consisting of a plurality of filter cartridges according to the prior art, the connection between each filter cartridge is made of nipples and connecting parts and hoses, which makes it difficult to replace the filter.

In addition, since the reverse osmosis membrane filter cartridge is formed by separating the purified water discharge hole and the concentrated water discharge hole according to the characteristics of the product, the cost cost increases, and separate parts such as a hose and a connecting member are required when connecting the filter cartridge and the filter cartridge forming the water purification system. Is inconvenient when installing in a narrow space or a narrow space, and workability to assemble is inferior, and ordinary consumers who do not have the expertise or inexperience required to replace the filter cartridge can not easily replace the filter cartridge. There was a problem.

It is mounted and coupled using the adapter 600 serves as a flow passage of raw water, purified water. In addition, the connection structure of the water purification system is simplified by the structure of the connector 500 including the reverse osmosis membrane filter cartridge 300 in which passages of raw water, purified water and concentrated water are formed in one port shape, thereby simplifying the assembly work. There is an advantage.

In the above system, when an auto shutoff valve or a solenoid valve is installed to cut off the raw water according to the constant hydrostatic pressure required by the water purification system, a separate configuration must be added.In addition, the activated carbon discharge passage is required when flushing is required. There is a problem that it is necessary to build a separate additional equipment for.

In order to solve the above problems, the present invention is equipped with a water purification system to easily replace the filter cartridge using a connector, the adapter can be changed according to the installation environment can be changed appropriately according to the installation environment between the connector It is an object to provide a water purification system.
