Under the state of stopping the machine and not making water, certain pressure is arranged in the membrane shell of the RO filter element, and only very small water flows out of the wastewater electromagnetic valve, so that the wastewater discharge time is too long. Especially, for the case of the situation that wastewater needs to be collected, after the wastewater container is full, the wastewater container needs to be taken away to treat the wastewater, the wastewater of the water purification device continuously flows out at the moment, and the time for all the wastewater to flow out is about 5 minutes, so that a user needs to spend time waiting for the wastewater to completely flow out when treating the wastewater, and the experience is very poor.

the method is characterized in that: the waste water end of the RO filter element is connected to a waste water outlet through a waste water pipeline, and a second electromagnetic valve and a second check valve which are arranged in parallel are arranged on the waste water pipeline; the booster pump further comprises a control module, and the control module controls the on-off of the first electromagnetic valve, the second electromagnetic valve and the booster pump.
Preferably, the first electromagnetic valve and the second electromagnetic valve are both in a normally closed structure.
Preferably, a front filter element is arranged between the raw water inlet and the first electromagnetic valve, and a rear filter element is arranged between the RO filter element and the water outlet faucet.
The second technical scheme of the invention is as follows: when the water purifier is used for normally producing water, the first electromagnetic valve and the booster pump are in an open state, the RO filter element normally works, pure water flows out from the water outlet faucet, at the moment, the second electromagnetic valve is in a closed state, and the wastewater flows out from the wastewater outlet through the second check valve; when stopping system water, first solenoid valve, booster pump are the off-state, open the second solenoid valve, and waste water passes through the second solenoid valve and flows from the waste water export, and when the second solenoid valve opened 10 seconds after, waste water end water pressure is less than the switching-on pressure of second check valve, closes the second solenoid valve, and the waste water export stops out water.
Preferably, when the water production is stopped, the second electromagnetic valve is opened, so that the water pressure at the waste water end is lower than 80% of the conduction pressure of the second check valve.
The second electromagnetic valve and the second check valve which are connected in parallel are arranged at the waste water end of the RO filter element to control the discharge of waste water, when water is normally produced, the waste water passes through a water channel where the second check valve is located, the conduction pressure of the second check valve is 2.5MPa, and the waste water pipeline is in an open state, so that the normal discharge requirement of the waste water can be met; and under the state of shutting down not making water, the inside pressure of RO filter core makes the waste water end continue to discharge waste water, opens the second solenoid valve this moment, and waste water is discharged from the water route of second solenoid valve place, reduces the pressure of waste water end fast, makes it be less than 80% of second check valve turn-on pressure, at this moment, closes the second solenoid valve, and the waste water pipeline also becomes closed state, makes waste water not flowing, reaches the effect of timely stagnant water.
The invention controls the discharge of the waste water through the electromagnetic valve and the check valve which are arranged in parallel, and switches the discharge channel of the waste water under different states of water making, flushing, water making stopping and the like, thereby not only meeting the discharge requirement of the waste water in normal water making, but also playing the role of stopping the flow of the waste water in time.
