The application principle of the water purification system is as follows:
in the pure water making process, the pure water output end 2 and the raw water input end 1 are opened, the pressurizing assembly 6 is opened, and water flows along the water inlet flow passage and the pure water flow passage to make pure water making.
The reverse osmosis filter core component 7 produces concentrated water while pure water produces water; at this time, the drain control valve 32 is closed, the return control valve 31 is opened, and the generated concentrate flows back to the water tank assembly 5.
The returned concentrated water is mixed with the input raw water at the position of the water mixing end 501 of the water tank assembly 5, and the fully mixed water source is led out again at the position of the water outlet end 502 and input into the water inlet 71 of the reverse osmosis filter core assembly 7. The mixed water source organization and the recycling of the backflow concentrated water and the raw water prevent the concentrated water with high TDS value from being directly re-input into the reverse osmosis filter element assembly 7 to influence the service life of the reverse osmosis filter element assembly 7.
Based on the combination setting of raw water TDS determine module 12, pure water TDS determine module 23, the pure water source TDS value of the output is surveyed from water tank set spare 5 to the mixed water source TDS value of output separately, is surveyed from the pure water mouth 72 output of reverse osmosis filter core subassembly 7 and reads. Based on the prior art application of the statistical calculation of the salt rejection rate, the TDS value of the mixed water source and the TDS value of the pure water source can be subjected to the numerical value of the salt rejection rate (salt rejection rate = (total feed water salinity-total product water salinity)/total feed water salinity × 100%). The reference standard value of desalination rate is preset (85%), when the detected desalination rate is less than the reference standard value, the quality of the pure water obtained by subsequent preparation is considered to be influenced by the reflowing concentrated water. At this point, the water purification system will be put into a rinse phase: at this time, the water outlet 4 is closed, the pure water outlet 2 is closed, the return water control valve 31 is closed, and the drain control valve 32 is opened, so that the raw water side of the reverse osmosis filter element assembly 7 is sufficiently flushed with the raw water continuously fed from the raw water inlet 1, and all the water sources generated by the flushing are discharged at one time.
After the washing is accomplished, the water source does not contain dense water in the water tank subassembly 5, and the TDS of the side of intaking in the reverse osmosis filter element group spare 7 and dense water side all effectively reduces, has satisfied the high standard pure water of next stage and has prepared the application demand.

When the water purification system is in a standby state, the pure water output end 2 is closed, and a water source full of water is left in the water tank assembly 5. Although this portion of the remaining water source is mixed with a concentrate having a higher TDS value, it is treated by the reverse osmosis cartridge assembly 7 and filtered by the pre-filter cartridge assembly 10, which has a substantially higher filtration standard than untreated raw water, and is therefore available for direct access by the user for daily use.
And when domestic water was got, raw water input 1 opened, and the raw water energy of newly introducing does further dashing with former mixed water source of saving in water tank set spare 5 again and mixes, can make the TDS value of water source further reduce in this water tank set spare 5, and then effective positive feedback has ensured reverse osmosis filter element group spare 7's life more effectively in subsequent pure water system water flow.
