Description

One-Touch Detachable Adapter

The present invention relates to a one-touch detachable adapter in which a filter assembly used for a bidet, a water purifier, an ion water dispenser, a refrigerator, or other functional water makers is installed. In particular, a rotating body is separately provided inside the adapter body to facilitate attachment and detachment of the filter assembly. A one-touch removable adapter that does not require a check valve for opening the flow path.

By filter is meant filtration means used in devices that provide specific functional water, such as water purifiers, ionizers, and the like. As water pollution becomes more severe, users are increasingly concerned about the hygiene level of drinking or using water. According to such a situation, the demand for water purifiers including filters is increasing rapidly. Currently, a large number of home users or restaurants use water purifiers.

1 is a schematic configuration diagram of a general water purification system using a reverse osmosis membrane filter.

As shown in the figure, a non-woven fabric removes macro-sized foreign substances from rust, soil, sand, and suspended solids contained in raw water (tap water, groundwater) flowing through a hose connected to a faucet (not shown). A sediment filter (1), a precarbon filter (2) for removing chlorine components, organic chemicals, etc. remaining in water by adsorption of activated carbon made by burning mineral or palm trees at high temperatures, and a polyamide composite membrane Reverse osmosis membrane filter (R / O filter) 3 which purifies various pollutants, bacteria, inorganic substances, heavy metals, etc. in water through fine pores of 0.0001 micron size, and foreign substances such as odor, gas component in water It is made of a post carbon filter (4) to improve the taste of the water by treatment.

At this time, the concentrated water filtered by the reverse osmosis membrane filter 3 is discharged to the outside through the concentrated water control valve (5).
