Background

Along with the improvement of living standard of people, people have higher requirements on the quality of drinking water, the water purifier is widely welcomed, the current large-flow water purifier gradually becomes the mainstream of the market, but some defects also exist, such as the large area of the membrane and the high proportion of pure waste cause that high-concentration waste water between the membranes and pure water in the membrane pure water flow channel are positively permeated after the water purifier is shut down, and the TDS value of outlet water begins to obviously increase after the water purifier is shut down for 5 minutes; in addition, the problem that the pipeline machine is repeatedly and rapidly started and stopped when the large-flow water purifier is connected with the pipeline machine is particularly outstanding, the water flow produced by the pipeline machine is about 0.8 liter per minute, and the water produced by the large-flow water purifier generally exceeds the flow rate, so that the machine can be frequently started and stopped. In the market, a pressure barrel is added at a water outlet end to dilute a first cup of polluted purified water for solving the problem of stale water, for example, the pressure barrel is CN212640101U, is named as a double-core reverse osmosis water purification system and a double-core reverse osmosis water purifier, and the purified water in the pressure barrel is influenced and increased after being used for a long time, so that the effect is not obvious.

The method for realizing the main stream zero-old water of other manufacturers is that purified water polluted in the membrane is conveyed to the membrane again for secondary filtration after the membrane is stopped for 10 minutes until the TDS value in the membrane reaches a low value, but the TDS value is obviously increased after the membrane is stopped for 5 minutes, and the high-purity waste ratio is required to be realized, so that the problem that water is unqualified when the water is taken in 10 minutes after the membrane is stopped in an area with a high original TDS value is solved.
