Reverse osmosis system

A reverse osmosis system comprising

• a water supply connected to a first water tube and a second water tube to split water flow into two directions;
• a reverse osmosis filter connected to the first water tube for water inflow and connected to a drain pipe which is connected to a wastewater tank;
• wastewater, which is generated from the reverse osmosis filter, is configured to be discharged into the wastewater tank through the drain pipe;
• and
• a mixing member having a water inlet end, a water outlet end, and a wastewater inlet tube, which are communicated with each other, and the water inlet end of the mixing member connected to the second water tube;
• the wastewater inlet tube and the water outlet end respectively connected to the wastewater tank and a water device;
• a mixing chamber, which is formed inside the mixing member, communicated with the water inlet end and the water outlet end at two ends thereof;
• the mixing chamber communicated with the water inlet end through a tapered water inlet hole which has a gradually-larger diameter from the mixing chamber to the water inlet end while the mixing chamber communicated with the water outlet end through a tapered water outlet hole which has a gradually-larger diameter from the mixing chamber to the water outlet end;
• the mixing chamber communicated with the wastewater inlet tube through at least a pore;
• the mixing member connected to the wastewater inlet tube through a first connecting member which comprises a first non-return member installed therein;
• when water flowing from the water inlet hole through the mixing chamber to the water outlet hole, the negative pressure, which is generated to the pore, adapted to move the first non-return member in the first connecting member so as to pump wastewater in the wastewater tank through the wastewater inlet tube into the mixing chamber to mix with water flowing through the mixing chamber, thereby achieving the effect of water saving.
