2, active carbon filter core filter 3 and ultrafiltration membrane filter element filter 4, obtains after the outlet 43 of ultrafiltration membrane filter element filter is filtered
Purification moisture is two-way, and wherein a road purification water obtains domestic water through double faucet 13, and another road purifies water and enters reverse osmosis
Permeable system obtains pure water, and purification water obtains the water route of pure water and sequentially passes through entering water electromagnetic valve 5, booster pump 6, reverse osmosis membrane mistake
First import 71 of filter, the outlet 72 of reverse osmosis membrane filt, H-shaped expansion the first import 91 of drain valve, H-shaped expand hydrophobic
First outlet 92 of valve, high-voltage switch gear 10 finally enter pressurized tank 14 and store.
The present invention, by adjusting the internal structure of reverse osmosis membrane filt 7, changes reverse osmosis membrane filt 7 internal watercourses and leads
Stream, functionally realizes " two enter singly to go out ", is the water that " stagnant water " water conservancy diversion becomes flowing capable of circulation by the water that cannot flow inside filter element,
And realize bactericidal cleaning developing result by H-shaped expansion 9 pairs of water route technology of drain valve.
Wherein, under normal circumstances, high-voltage switch gear 10 is in normally off, enters pressurized tank for water route by high-voltage switch gear 10
14, pressurized tank 14 is for storing the pure water of gained, and along with in pressurized tank 14, water level rises, in pressurized tank 14, air is compressed,
Pressure increases therewith, and when in pressurized tank 14, pressure reaches the pressure upper limit value of defined, pressurized tank 14 sends signal, water inlet electricity
Magnet valve 5 disconnects after receiving signal so that purification water can not refilter and obtain pure water, and along with user's continuation water, pressurized tank 14
Compressed air by the hydraulic pressure access customer grid in pressurized tank 14, pressurized tank 14 water level decreasing, tank inner air pressure also with
Decline, when pressurized tank 14 inner air pressure is down to required threshold pression value, pressurized tank 14 sends signal, electromagnetism of intaking
Valve 5 enters normally off, purifies water continuation purification and obtains pure water.High-voltage switch gear 10 reaches the upper limit for pressure in pressurized tank 14
And in the case of entering water electromagnetic valve 5 is malfunctioning, disconnect water route, play the effect of dual fail-safe.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
