Disclosed is a central tube set. The central tube set includes: a permeate tube, a peripheral wall of the permeate tube being arranged with a pure water influx hole communicating with an internal channel of the permeate tube; and a plurality of wastewater tubes arranged at intervals. The wastewater tubes are arranged around the permeate tube, a peripheral wall of each wastewater tube is arranged with a wastewater influx hole communicating with an internal channel of each wastewater tube. The plurality of the wastewater tubes and the permeate tube are arranged at intervals, to form a receiving space between each wastewater tube and the permeate tube, for receiving a portion of the reverse osmosis membrane sheet set which is extending into the central tube set. The present application further provides a spiral wound reverse osmosis membrane component and a reverse osmosis water purifier.

Central tube set, spiral wound reverse osmosis membrane component, and reverse osmosis water purifier

A central tube assembly for a filter cartridge and a manufacturing method for the central tube assembly are provided. The central tube assembly includes a first half-tube defines a first flow passage, and having a first water inlet at an end thereof and a water output hole in a side wall thereof, a filtering membrane bent to form a first membrane layer and a second membrane layer, the first half-tube being disposed between the first membrane layer and the second membrane layer; an input-water filtering net connected to the first half-tube and disposed between the first membrane layer and the second membrane layer, a second half-tube disposed outside of a bending of the filtering membrane, defining a second flow passage, and having a water input hole in a side wall thereof and a first water outlet at an end thereof, and a produced-water filtering net.
