Abstract:
A reverse osmosis water treating device comprising:a. a preliminary filtering unit, a reverse osmosis membrane unit, pipeline assemblies, and a tube connecting unit disposed between said pipeline assemblies; b. said tube connecting unit including a tube body comprising a water outgoing end, a water incoming end, and a diaphragm disposed between said ends dividing the tube body into two sections, said diaphragm including a passage having a check valve therein adapted to allow one-way flow between said water incoming end and said water outgoing end, said two sections respectively including first and second through-holes formed in lateral walls of the tube body; and c. said pipeline assemblies including a first pipeline assembly and a second pipeline assembly, one end of the first pipeline assembly being connected to the first through-hole in fluid communication with the water incoming end, another end of the first pipeline assembly being connected to the preliminary filtering unit and the reverse osmosis membrane unit, one end of the second pipeline assembly being connected to the second through-hole in fluid communication with the water outgoing end, another end of the second pipeline assembly being connected to a waste water draining end of the reverse osmosis membrane unit, said water outgoing end including a water valve adapted to deliver water for non-drinking uses, wherein said water for non-drinking uses has first passed through said preliminary filtering unit and said reverse osmosis unit draining end before passing through said water valve.
