[0002] With the development of society, reverse osmosis water purifiers (purified water machines) are becoming increasingly popular and widely welcomed. However, when existing RO water purifiers are not used for a long time, the water in the water inlet pipe becomes stagnant, and the residual chlorine in the water will dissipate. Without the suppression of residual chlorine, bacteria on the filter surface will multiply rapidly at a suitable temperature. The combination of large amounts of bacteria, organic matter, and sulfates may produce water-soluble and malodorous gases such as hydrogen sulfide (H2S) and ammonia (NH3). These gases can pass through the RO membrane and enter the purified water, resulting in foul-smelling water, causing odor and health problems. Therefore, improvements are needed to the water purifier and its water system to ensure that water quality does not affect people's daily lives. Utility Model Content

Through the setting of the fresh-keeping valve, the user can switch the fresh-keeping flushing program by turning the binary dial to maintain the freshness and residual chlorine concentration of the water entering the pure water machine, inhibit the bacterial growth on the surface of the filter element, thereby reducing and eliminating the concentration of malodorous gases in the water to ensure the cleanliness and freshness of the pure water outlet, and completely solve the problem that the pure water machine is prone to stink when it is not used for a long time. On the other hand, while using the fresh-keeping valve to keep the pure water fresh, it also protects the filter element in the reverse osmosis water purifier and flushes the RO membrane to prevent it from being troubled by bacteria and smelly water, thereby protecting their normal service life and bringing great convenience to the user.
[0026] Based on the above embodiment, in other embodiments, the computer chip is further provided with eight fresh-keeping flushing programs, including:
[0027] The flushing cycle is 12 hours, each flushing is 46 seconds, and the flushing frequency is 92 seconds / day;
[0028] The flushing cycle is 1 hour, each flush is 23 seconds, and the flushing frequency is 552 seconds / day;
[0029] The flushing cycle is 2 hours, each flushing is 46 seconds, and the flushing frequency is 552 seconds / day;

[0033] No cycle program, just flush for 60 seconds when plugged in;
[0034] There is no cycle and no flushing program, and the default flushing time is 0 seconds.
[0035] The above eight fresh-keeping and rinsing programs can be activated by simply turning the binary dial 6. Figure 2 , there are three dials on the binary dial 6. To simplify the explanation, turn the dial to the ON end, marking 0, and turn the dial to the "123" end, indicating 1:
[0036] 0-0-0: The fresh-keeping valve flushes for 23 seconds after being plugged in, and the flushing cycle is 12 hours, with each flush lasting 46 seconds, and the flushing time is 92 seconds per day;
[0037] 0-0-1: The fresh-keeping valve flushes for 23 seconds after being plugged in. The flushing cycle is 1 hour, with each flush lasting 23 seconds, and the flushing time is 552 seconds per day.
[0038] 0-1-0: The fresh-keeping valve flushes for 23 seconds after being plugged in, and the flushing cycle is 2 hours, with each flush lasting 46 seconds, and the flushing time is 552 seconds per day;
[0039] 0-1-1: The fresh-keeping valve flushes for 23 seconds after being plugged in, and the flushing cycle is 12 hours, with each flush lasting 92 seconds, and the flushing time is 184 seconds per day;

[0045] The first six fresh-keeping flushing programs mentioned above are all applicable to the selected RO membrane pulse program. Users can choose the daily cycle flushing and fresh-keeping program and flushing time according to actual conditions (the flushing time is the time when the power is plugged in), so as to ensure the freshness of the pure water and the residual chlorine content of the inlet water, and inhibit bacterial growth; at the same time, the selection should take into account both water saving and taste.
[0046] On the basis of the above embodiments, in other embodiments, a TDS probe 32 is further provided at one end of the high-pressure switch 31. The TDS probe 32 is used to detect and monitor the purity of water.
