Traditional reverse osmosis water purification machines have water production capacity of 50 gallons per day, and water production capacity of 400 gallons, 800 gallons and even more than 1000 gallons is generally called as large-flux water purification machine, and the large-flux water purification machine improves certain performances and brings new problems in aspects of sanitation indexes and cost performance, so that a 'water retention' problem is generated.
The water flow channel of the prior reverse osmosis membrane filter element (RO filter element) has the following structure: raw water enters from one end of the filter element, the raw water is filtered from outside to inside, the filtered pure water flows out through the central tube, and the filtered concentrated water is arranged on the outer side of the central tube. The concentrated water at the concentrated water side of the reverse osmosis filter element contains high-concentration ions and organic matters which can be slowly diffused to the pure water side, and if the time is long enough, the concentrations at the two sides can reach balance. If the pure water is diffused overnight, the TDS value of the pure water in the pure water side is obviously increased, and if heavy metal ions in the raw water are more, the heavy metals in the pure water also exceed the standard, so that the water quality and the taste are greatly influenced.
When the large-flux water purifier works, the TDS at the pure water end is in a normal state, when a user stops using the large-flux water purifier, the concentrated water at the RO membrane water inlet end can be gradually diffused to the pure water end, the diffusion time of the concentrated water starts to appear within 5 minutes, the water at the pure water end is generally determined according to the size of the membrane shell, about 500 plus 1000ml is generally generated, and the TDS value of the first cup of water after the water starts to work again is higher.

Therefore, the technical scheme of the utility model is that: a water purifier for replacing concentrated water with pure water comprises a raw water inlet, wherein the raw water inlet is sequentially connected with a first water inlet electromagnetic valve and a booster pump; the booster pump is connected with the water inlet end of the RO filter element, and the concentrated water end of the RO filter element is connected to the waste discharge port through a concentrated water electromagnetic valve;
the method is characterized in that: the pure water end of the RO filter element is divided into two paths, one path is connected to a water outlet faucet through a first check valve and a high-pressure switch, and the other path is connected to a water inlet of the booster pump through a second water inlet electromagnetic valve and a second check valve; the water pump also comprises a control module, and the control module controls the on-off of the first water inlet electromagnetic valve, the booster pump and the second water inlet electromagnetic valve.
Preferably, the second water inlet electromagnetic valve is communicated with the pure water end and the water inlet end of the RO filter element.
Preferably, the pure water end of RO filter core is provided with the TDS probe on connecting out tap's the pipeline, detects the TDS value of pure water.
Preferably, the first and second water inlet solenoid valves are flow regulating valves, and the control module regulates the flow rates of the first and second water inlet solenoid valves.
When the water outlet faucet is opened, the first water inlet electromagnetic valve is opened, the second water inlet electromagnetic valve is opened for 5 seconds and then closed, and the RO filter element produces water normally; when the water outlet faucet is closed, the second water inlet electromagnetic valve is opened, the first water inlet electromagnetic valve is closed after running for 1 minute, pure water generated by the RO filter element enters the water inlet end of the RO filter element to be mixed with raw water, so that concentrated water in the RO filter element is replaced, and after the first water inlet electromagnetic valve is closed for 30 seconds, the booster pump and the second water inlet electromagnetic valve are closed; and after the water outlet faucet is closed for 10 seconds, the concentrated water electromagnetic valve is in a full-open state.
The utility model discloses a first, second solenoid valve of intaking can make into adjustable flow valve, can adjust the flow according to the TDS value after shutting down to the adjustment gets into the proportion of raw water and pure water in the RO filter core, more accurate reduction TDS value.
The utility model discloses increase a pure water backward flow route on the basis of traditional big flux purifier, and after shutting down, the pure water that utilizes the RO filter core to produce removes the dense water in the replacement RO filter core self, make the dense water of RO filter core serve the mixed raw water that whole becomes raw water and pure water, reduce the ion concentration of the interior dense water side of RO filter core, solve the ion diffusion problem, make the TDS of pure water serve interior pure water can not rise, solve the problem that big flux first cup of water TDS value is on the high side through this kind of pure water backward flow mode.
