Detailed description of the invention
See accompanying drawing.The present embodiment includes RO filter element 2 and pressure pot 3, and the water side of described RO filter element 2 connects pressure pot 3 by non-return valve 4；It is flexible structure that pressure pot is divided into pure water district 32 and waste water district 33, barrier film 31 by barrier film 31 by described pressure pot 3, movable with the pressure change of both sides, transmits pressure；The water outlet in described pure water district 32 is divided into two-way, and a road connects pressure switch 6, and another road connection traffic switch 7, flow switch 7 connects depotition cock 10；The waste water end of described RO filter element 2 is connected to the waste water district 33 of pressure pot by the second electromagnetic valve 8, and the waste water district 33 of pressure pot connects discharge outlet by the 3rd electromagnetic valve 9.
During the present embodiment work, tap water is directly entered RO filter element 2 and starts controlling the water circulation, and the pure water of RO filter element 2 initially enters the pure water district 32 of pressure pot 3.When, after the full pure water of pressure pot 3 system, pressure reaches balance；As shown in Figure 2, when depotition cock 10 is opened, pure water is extruded pressure pot 3 by the pressure in pure water district 32, when flow switch 7, to detect that water flows through out-of-date, second electromagnetic valve 8 is opened, 3rd electromagnetic valve 9 cuts out, and the waste water that RO filter element 2 produces enters the waste water district 33 of pressure pot by the second electromagnetic valve 8, and the pure water in pure water district 32 is extruded by the pressure that waste water district 33 increases；
As it is shown on figure 3, when depotition cock 10 is closed, flow switch 7 detects signal, the second electromagnetic valve 8 cuts out, and the 3rd electromagnetic valve 9 is opened, and the water in pressure pot waste water district 33 is expelled directly out by the 3rd electromagnetic valve 9.Now the pressure of pressure pot 3 is zero, and RO filter element 2 is through the pure water district 32 of the pressure controlling the water circulation entrance pressure pot of tap water, until controlling the water circulation completes.
As shown in Figure 4, the water inlet end of described RO filter element 2 connects the first electromagnetic valve 1, and the water outlet in described pure water district 32 is divided into two-way, and a road connects pressure switch 6, another road connection traffic switch 7.Described RO filter element 2 waste water end divides two-way, and a road connects waste water ratio control valve 5, and the second electromagnetic valve 8 of separately leading up to is connected to the waste water district 33 of pressure pot.Described waste water ratio control valve is to control the valve of discharge of wastewater.
When the RO machine of this structure works, first electromagnetic valve 1 is long open state, tap water is directly entered RO filter element 2 and starts controlling the water circulation, waste water ratio control valve 5 starts effluent, the pure water of RO filter element 2 initially enters the pure water district 32 of pressure pot 3, and now outlet and the 3rd electromagnetic valve 9 in the waste water district 33 of pressure pot connects, and the 3rd electromagnetic valve 9 is in normally open, communicating with air, the pressure in waste water district 33 is zero.Barrier film 31 in meeting squeeze pressure bucket when pure water enters pure water district 32, making the pressure pot 3 full pure water of system, now pure water district 32 pressure begins to ramp up, when the hydraulic pressure in pressure pot rise to tap water hydraulic identical time, when the signal of pressure switch 6 being detected, the first electromagnetic valve 1 cuts out；
When depotition cock is opened, pure water is extruded pressure pot 3 by the pressure in pure water district 32, when flow switch 7, to detect that water flows through out-of-date, second electromagnetic valve 8 is opened, 3rd electromagnetic valve 9 cuts out, when the pressure in pure water district 32 be gradually lowered to pressure switch 6 close time, the first electromagnetic valve 1 is opened, the waste water that RO filter element 2 produces enters the waste water district 33 of pressure pot by the second electromagnetic valve 8, and the pure water in pure water district 32 is extruded by the pressure that waste water district 33 increases；
When the faucet is turned off, flow switch 7 detects signal, and the second electromagnetic valve 8 cuts out, and the 3rd electromagnetic valve 9 is opened, and the waste water in pressure pot waste water district 33 is expelled directly out by the 3rd electromagnetic valve 9.Now the pressure of pressure pot 3 is zero, and the pressure reduction of RO filter element 2 controlling the water circulation becomes big, and RO filter element 2 is through the pure water district 32 of the pressure controlling the water circulation entrance pressure pot 3 of tap water, until after pressure switch 6 take-off, closing the first electromagnetic valve 1, complete machine quits work.
As it is shown in figure 5, the water inlet end of described RO filter element 2 connects preposition filter element 11, preposition filter element 11 includes but not limited to following kind, including stainless steel filtering net, PP cotton, granular active carbon, extruded activated carbon and combinations thereof.
As shown in Figure 6, it is provided with rearmounted filter element 12 between described flow switch 7 and depotition cock 10, improves mouthfeel.
Flow switch 7 in all structures of the present embodiment can be replaced by Water flow detector, detects that current, pressure switch 6 are replaced by pressure-detecting device or condensate tank of dehumidifier, and RO filter element 2 can be replaced by NF membrane filter element.
