As preferably, between the first pressure switch and water pump, be provided with the second reverse checkvalve.Second reverse checkvalve makes condensed water not reflux, in order to avoid produce back pressure.Second reverse checkvalve is the front end sluice gate of the first pressure switch simultaneously, and the pressure at the concentrated mouth of a river is consistent with first all the time to make the first pressure switch pressure.
As preferably, between water-in and topping-up pump, be also in series with fore filter and the second magnetic valve successively.Fore filter filters the water entering water purifier.When system stops water processed, the second solenoid valve shuts system water source, under preventing tap water pressure effect, water slowly causes wastewater streams not stop through reverse osmosis membrane.
As preferably, also comprise two depotition cock, two depotition cock has two water-ins, and two water-ins are connected with the first condensed water water outlet with pure water water outlet respectively.User can by the two depotition cock choice for use pure water of operation or condensed water.
As preferably, two depotition cock is two water outlet gooseneck faucets.
The present invention, owing to have employed above technical scheme, has significant technique effect: when using pure water, the second magnetic valve, topping-up pump are opened, the first solenoid closure, and the condensed water that reverse osmosis membrane filter element produces in continuous water processed flows in water tank.When water is full, the first water level sensor action in water tank, the first magnetic valve is opened, discharge condensed water.
When using condensed water, the first pressure switch action, condensed water flows out from water tank, when the condensed water stored in water tank runs low, use condensed water, the second water level sensor action in water tank if now also need, at this moment the second magnetic valve of intaking is opened, and water flows through from reverse osmosis membrane front surface.
The condensed water that the present invention can effectively store and utilize water-purifying machine to produce, reaches water saving, improves the utilization ratio of water, avoids the object of the waste of water resources.
