Abstract

A water treating device includes an outer casing, a reverse osmosis tube, a side cap, and an outlet tube. The outer casing includes an outer tube having a first inlet for water and a first outlet, an inner tube mounted inside the outer tube and including a number of holes defined in a periphery of an end thereof, and a water-permeable layer mounted between the inner tube and the outer tube. The reverse osmosis tube is mounted in the inner tube and includes a second inlet for water from the holes of the inner tube and adjacent to the end of the outer tube. The reverse osmosis tube further includes a second outlet for pure water. The side cap is mounted to seal a first end of the outer casing and includes a first electric rod to interconnect the outer tube with a positive power connection and a second electric rod to interconnect the inner tube with a negative power connection. The outlet cap is mounted to seal the other end of the outer casing and includes a third outlet communicated with the second outlet for pure water and a flood hole for outputting impure water. When power is supplied to the positive power connection and the negative power connection, water that enters a space between the inner tube and the outer tube is electrolyzed such that negative ionic water is outputted via the first outlet of the outer tube, and cationic water is passed through the reverse osmosis tube to proceed with acid wash on the reverse osmosis tube and then outputted via the flood hole of the outlet cap.
