By taking rear class filter core 10 is reverse osmosis membrane filter element as an example, the pollution at the wastewater outlet of reverse osmosis membrane filter element is the most serious, and this reality
Example is applied in such a way that the water inlet end from the wastewater outlet of reverse osmosis membrane filter element to reverse osmosis membrane filter element rinses to reverse osmosis membrane filtration
Core is rinsed, on the one hand, purified water can form powerful shearing force on the surface of reverse osmosis membrane, to mitigate fouling membrane, more
Be conducive at the wastewater outlet of reverse osmosis membrane filter element and the purification of entire reverse osmosis membrane filter element and the raising of flux；On the other hand,
Reverse osmosis membrane filter element is immersed in purified water, and since the purity of water is higher, Gibbs free energy is higher, and has spontaneous reduction
Trend, and water itself can not reduce Gibbs free energy, can only be by dissolved impurity, realizing reduces Gibbs free energy
Purpose, so, purified water impregnates reverse osmosis membrane filter element and is easier to mitigate the pollution of reverse osmosis membrane filter element.
The wastewater outlet of rear class filter core 10 is communicated with the useless delivery pipe of waste water, is provided with discharge of wastewater electromagnetism on wastewater discharge pipe
Valve, when needing to be rinsed rear class filter core 10, discharge of wastewater solenoid valve is closed, and the first solenoid valve 3 and second solenoid valve 4 are beaten
It opens.
Further, it is arranged on the pipeline between discharge of wastewater solenoid valve and the wastewater outlet of rear class filter core 10 proportional
Valve.
In the optional technical solution of the present embodiment, the water purification end of front filter element is provided with flowmeter.
Further, in the optional technical solution of the present embodiment, flushable long-acting water purifier includes controller, flowmeter and
Inlet water solenoid valve 92 is connect with controller.Flowmeter monitors the net water flux data at front filter element water purification end, and controller receives
Net water flux data.When net water flux data are zero, controller controls inlet water solenoid valve 92 and closes.
After user's water, front filter element and rear class filter core 10 continue water processed, the water purification end output of rear class filter core 10
Water can enter water container 20, be stored into water container 20, the hydraulic pressure in water container 20 and 10 water purification end of rear class filter core
Hydraulic pressure it is equal when, front filter element and rear class filter core 10 stop water processed, and net water flux data are zero, before controller can then judge
It sets filter core and rear class filter core 10 has stopped water processed, to control the closing of inlet water solenoid valve 92.
When flushable long-acting water purifier normally produces water, the first solenoid valve 3, second solenoid valve 4, the 5, the 4th electricity of third solenoid valve
Magnet valve 6, the 6th solenoid valve 8, the 7th solenoid valve 9 are closed, inlet water solenoid valve 92, the 5th solenoid valve 7, the 8th solenoid valve 91, waste water
Discharge solenoid valve is opened, and carries out production water by 10 rate of recovery of ratio valve regulation rear class filter core.
In the optional technical solution of the present embodiment, booster pump has been can be set in the water inlet end of rear class filter core 10.Purified water warp
When check-valves 1 enters water container 20, purified water institute band pressure also enters water container 20 together and stores.
It should be noted that the purified water mentioned in this implementation refers to the water of the output after the purification of corresponding filter core.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type.
