WATER PURIFICATION SYSTEM WITH AUTOMATIC FLUSH FLOW

摘要

The improved water purification system includes a water purification unit having a tap water inflow port for receiving a tap water inflow from a water supply system to produce relatively purified water and a brine water outflow having impurities concentrated therein. An RO filter having an RO membrane separates relatively unfiltered water flow into purified water and the brine water outflow. A flush flow activation chamber fluidly coupled to the brine water outflow includes a plunger for substantially occluding brine water outflow through the brine outflow port when seated, and substantially permits brine water outflow to exit the purification unit through the brine outflow port when unseated. Accordingly, the activation chamber generates back pressure within the water purification system to flash flow tap water inflow into the purification unit and through the RO membrane when the plunger moves from being seated to unseated, thereby substantially refreshing said RO membrane.

1. A water purification system with automatic flush flow, comprising:
a water purification unit having a tap water inflow port for receiving a tap water inflow from a water supply system to produce a supply of relatively purified water discharged from said unit via a purified water outflow port, and a brine water outflow having impurities concentrated therein and discharged from said unit via a brine outflow port; said purification unit including an RO filter having an RO membrane for separating relatively unfiltered water flow into said purified water and said brine water outflow; and a flush flow activation chamber fluidly coupled to said brine water outflow and having a plunger therein for substantially occluding said brine water outflow through said brine outflow port when in a first seated position, and substantially permitting said brine water outflow to exit said purification unit through said brine outflow port when in a second unseated position; said activation chamber generating back pressure within said water purification system to flash flow said tap water inflow into said purification unit and through said RO membrane when said plunger moves from said first position to said second position, thereby substantially refreshing said RO membrane.
