The concentrated water discharge pipe 301 is connected to the waste water barrel 5. The waste water discharge pipe 501 is fixed at the bottom of the waste water barrel 5. The pure water end is fixed with the pure water discharge pipe 4.

The backwash return pipe 104, the wastewater return pipe 102, the clean water pipe 105 and the sewage discharge pipe 501 are all provided with solenoid valves 6, and the wastewater return pipe 102 and the backwash return pipe 104 are provided with a booster pump 7.

A turbidity detector 8 is provided in the raw water end of the pre-filter element 1 and in the bottom of the waste water barrel 5; a liquid level sensor 9 is provided in the upper part of the waste water barrel 5.

The water purifier system also includes a central controller, a wireless communication module and an intelligent terminal; the solenoid valve 6, the turbidity detector 8, the booster pump 7, and the liquid level sensor 9 are all electrically connected to the central controller and the wireless communication module. The central controller and the wireless communication module are fixed on the water purifier, and the central controller communicates wirelessly with the smart terminal through the wireless communication module.

The raw water inlet pipe 101 is provided with a pressure stabilizing valve and a one-way valve in sequence from the far end to the proximal end, and the backwash return pipe 104 is provided between the one-way valve and the raw water inlet on the pre-filter element 1 . The pressure stabilizing valve 10 is used to prevent excessive flow of raw water from damaging the pre-filter element. The one-way valve 11 can ensure that the water flow will not flow into the far end of the raw water outlet pipe 101 in the reverse direction.

The far end of the raw water inlet pipe 101 is connected to a tap water pipe or a raw water storage bucket.

The middle filter element 2 is an ultrafiltration membrane filter element.

Working principle: When the water purifier is turned on, raw water flows from the raw water inlet pipe 101 through the pressure stabilizing valve and the one-way valve into the pre-filter element 1. The raw water is filtered through the pre-filter element 1 to obtain purified water. The purified water enters the intermediate filter element 2 through the water purification pipe 105 for further filtration. The filtered water then enters the RO reverse osmosis filter element 3 through the water purification pipe 201 for further filtration to obtain pure water.

When the pre-filter element 1 performs filtration to obtain purified water, wastewater will be generated at the raw water end. The wastewater will be discharged into the wastewater barrel 5 through the wastewater discharge pipe 103. At the same time, when the RO reverse osmosis filter element 3 filters to obtain pure water, wastewater will be generated at the reverse osmosis purified water end. Concentrated water is generated, and the concentrated water is discharged into the waste water barrel 5 through the concentrated water discharge pipe 301.

The turbidity detector 8 and the liquid level sensor 9 will collect the turbidity and liquid level in real time and upload the data to the central controller.

When the turbidity detector 8 located in the pre-filter element 1 detects that the turbidity of the raw water end is greater than the preset turbidity upper limit in the central controller, and the turbidity detected by the turbidity detector 8 in the waste water barrel 5 is less than the waste water barrel 5 When the turbidity is preset, the central controller will issue instructions to open the solenoid valve 6 and booster pump 7 on the wastewater return pipe 102. At this time, the wastewater in the wastewater barrel 5 will flow back to the pre-filter 1 and flush the pre-filter 1. , the flushed wastewater is discharged to the wastewater barrel 5 through the wastewater discharge pipe 103. When the turbidity detected by the turbidity detector 8 in the front filter element 1 is lower than the preset turbidity lower limit, the central controller receives this information and issues an instruction to close the solenoid valve 6 and booster pump 7 on the wastewater return pipe 102 , stop flushing the pre-filter element 1. At this time, when the turbidity detected by the turbidity detector 8 in the waste water barrel 5 is greater than the preset turbidity value of the waste water barrel 5, the central controller opens the solenoid valve 6 on the sewage discharge pipe 501 to discharge the turbidity in the waste water barrel 5. The sewage is discharged to the sewer and backwashing is completed. If the turbidity detected by the turbidity detector 8 in the waste water barrel 5 is lower than the preset turbidity value of the waste water barrel 5 at this time, the backwashing ends.

When the turbidity detector 8 located in the pre-filter element 1 detects that the turbidity of the raw water end is greater than the preset turbidity upper limit in the central controller, and the turbidity detected by the turbidity detector 8 in the waste water barrel 5 is greater than the waste water barrel 5 When the turbidity is preset, the central controller will issue an instruction to open the solenoid valve 6 on the sewage discharge pipe 501 to discharge the sewage in the waste water barrel 5. At the same time, the central controller issues instructions to open the solenoid valve 6 and the water pump on the backwash return pipe 104. At this time, the clean water filtered by the pre-filter 1 is returned through the backwash return pipe 104 to flush the pre-filter 1. The flushed wastewater is discharged into the wastewater barrel 5 through the wastewater discharge pipe 103. When the turbidity detected by the turbidity detector 8 in the front filter element 1 is lower than the preset turbidity lower limit, the central controller issues an instruction to close the backwash return. The solenoid valve 6 and booster pump 7 on the water pipe 104, and at the same time, if the turbidity value detected by the turbidity detector 8 in the waste water barrel 5 is less than the preset turbidity value of the waste water barrel 5, the central controller will issue a command to close Solenoid valve 6 on the sewage drainage pipe. At this time, backwashing ends.

When the liquid level sensor 9 on the waste water barrel 5 detects that the liquid level reaches the set upper limit, the central controller issues an instruction to open the solenoid valve 6 on the sewage drainage pipe to discharge the waste water in the waste water barrel 5. When the liquid level sensor 9 detects that the liquid level is less than the set lower limit of the liquid level, the central controller issues an instruction to close the solenoid valve 6 on the sewage drainage pipe and continue to collect wastewater.

When the water purifier system of the present invention needs to prepare pure water, the central controller sends an instruction to open the solenoid valve 6 on the water purification pipe 105, and the system starts to prepare pure water. During the backwashing process of the pre-filter element 1, the process of preparing pure water will not be affected.

The present invention effectively utilizes the waste water barrel 5 to collect waste water and concentrated water. When the pre-filter element 1 needs to be cleaned, the waste water in the waste water barrel 5 is pressed back to the pre-filter element 1 through the booster pump 7 for flushing, thereby effectively removing the waste water. At the same time, when the turbidity of the wastewater in the wastewater barrel 5 is too high to be used for flushing, the central controller will control the opening of the solenoid valve 6 on the sewage discharge pipe 501 to discharge the sewage that cannot be reused into the sewer. And when the wastewater in the wastewater barrel 5 is too turbid to be used for flushing, the system can also use the booster pump 7 to back-pump the clean water from the purified water end of the pre-filter 1 to the raw water inlet pipe 101, and flush the pre-filter 1 Perform backwash. And the wastewater after backwashing enters the wastewater barrel 5 again for recycling. Make maximum use of waste water and save water resources.
