Reverse osmosis membrane water purifier

The invention relates to the technical field of water purifiers, in particular to a reverse osmosis membrane water purifier which comprises a specially-made disc, a wastewater pipe is fixedly connected to the interior of the specially-made disc, and a plurality of supporting rib rods distributed in an annular array are fixedly connected to one side of the outer wall of the specially-made disc; and the ends, away from the special disc, of the supporting rib rods are fixedly connected with special circular rings, and first circular ring grooves are formed in the ends, away from the supporting rib rods, of the special circular rings. A water purification membrane is wound and fixed in the supporting rib rod, the special disc and the special circular ring, so that compared with the prior art that the water purification membrane is wound and fixed on the central water production pipe, the water purification membrane has the advantages that the minimum diameter of the water purification membrane is increased, and t
