The waste water flowed out from wastewater outlet 121 can be carried out secondary cycle.Further, during the rinsing process, then proportioning valve is needed
17 fully open, and the controlling valve 31 that flows back then completely closes, it is possible thereby to guarantee that waste water during the rinsing process is to flow away completely
's.For the water check valve 32 that flows back, function is identical as water check valve 16 above-mentioned, only the reflux water check valve
32 be the entrance so that the first order filter core of the waste water single flow direction multistage filter core flowed out from wastewater outlet 121, without
Meeting is so that the water of high-pressure water is entered in recirculation water branch by the reflux water check valve 32.Preferably, the water check valve
Need certain positive unlatching hydraulic pressure.Water check valve can be made to meet the item for opening hydraulic pressure by the positive hydraulic pressure of opening of setting
Ability one-way flow under part, therefore here it is just the other end of water check valve generate one when needing to be pressurized pump work to bear
Pressure could make water purification flow out from water check valve.This is but also rely solely on the hydraulic pressure of the water level generation in water purification storage box not
It will lead to the water check valve to open and flow out water purification.As can be seen that booster pump all plays in water processed and water purification flushing process
Effect can realize that function expands by the way that water check valve is rationally arranged on water route in this way under the premise of saving equipment as far as possible
Exhibition, the cost also reduced.

161 two sides are then provided with curved wall 164, such as are made of steel disc, are also equipped with below ball under permeable hole 166
Baffle 165.Under normal circumstances, the elastic force that spring 162 generates is in close contact ball 161 and lower baffle plate, and ball 161 is also with two
The curved wall 164 of side is in close contact, and the logical access of water flow is thus sealed between ball 161 and curved wall 164, and
Push ball 161 and the contact of curved wall 164 closer if hydraulic pressure from top to bottom is bigger, thus from top to bottom
Water route is blocked without that flowing water can be made to pass through.On the contrary, pushing ball 161 to transport upwards if hydraulic pressure from bottom to up is bigger
It moves to offset the elastic force of spring 162, so that the contact of ball 161 with curved wall 164 is loosened, until do not contact completely, thus
Meeting is so that water flows through 161 two sides of ball and flows through, and hydraulic pressure from bottom to up is bigger, then the open degree of the check valve is bigger.
It can further be seen that being that the water check valve is enabled to open, it is necessary to need certain unlatching hydraulic pressure, otherwise without
Method pushes ball 161 to move upwards the elastic force to overcome spring 162, it is preferred that the unidirectional unlatching hydraulic pressure of the water check valve is extremely
