A liquid level sensor is provided inside the pure water tank 3, and a flushing pipe 13 is provided at the bottom end of the pure water tank 3, and on which two branch pipes 14 are provided, which are respectively connected to the front end of the first booster pump 5 and the front end of the second booster pump 9, and the arrangement of the flushing pipe and the branch pipes can clean the filter equipment. The first filter group includes a multi-media filter 15 and a carbon filter 16, and the tap water is initially filtered through the multi-media filter 15 and the carbon filter 16 in sequence. The second filter group includes a nanofiltration unit 17 and a reverse osmosis unit 18; the first water outlet pipe 4 is connected to the water inlet pipes of the nanofiltration unit 17 and the reverse osmosis unit 18 through a tee pipe, and the fourth water outlet pipe of the nanofiltration unit 17 and the fifth water outlet pipe of the reverse osmosis unit 18 are connected to the clean water pipe 10 through a tee pipe; the concentrated water outlets of the nanofiltration unit 17 and the reverse osmosis unit 18 are both connected to the concentrated water discharge pipe 11. The first filter assembly, the precision filter 2 and the second filter assembly are all provided with a reserved water inlet for clean water washing.

[0015] Working principle: Start the equipment, tap water enters the raw water tank, passes through the first booster pump and enters the multi-media filter and carbon filter in turn for preliminary filtration of the tap water, the tap water after preliminary filtration passes through the precision filter for a second filtration, the tap water after the second filtration passes through the second booster pump and is divided into two paths to enter the nanofiltration unit and reverse osmosis unit for filtration, the water passing through the nanofiltration unit and reverse osmosis unit respectively flows from the clean water outlets of the nanofiltration unit and reverse osmosis unit to the clean water pipe, and then enters the pure water tank together for storage;

[0016] In the process of tap water filtration, the concentrated water produced after filtering by the nanofiltration unit and the reverse osmosis unit will be discharged through the concentrated water discharge pipe. However, since the concentrated water discharge pipe is connected to the return pipe, the concentrated water detector on the return pipe detects the quality of the concentrated water. When the quality of the concentrated water is lower than the set value, the concentrated water enters the raw water tank for re-filtration and processing. When the quality of the concentrated water is higher than the set value, the concentrated water is discharged through the concentrated water discharge pipe.

[0017] When the pure water tank is full of water, the solenoid valve on the raw water tank is closed, and the solenoid valve on the flushing pipe is opened, and the water inside the pure water tank is used to flush the first filter component, the precision filter, the second filter component and the pipes passing through.

[0018] The utility model connects a concentrate discharge pipe with a return pipe, and provides a concentrate detector on the return pipe. The concentrate detector detects the concentrate, recycles wastewater with a lower concentrate concentration and filters it, thereby reducing the discharge of wastewater and effectively solving the problem of water resource waste. A liquid level sensor is provided inside a pure water tank, and a flushing pipe is provided at the bottom of the pure water tank. A branch pipe on the flushing pipe can clean the filtering device after the pure water tank is full of water through the cooperation of a first booster pump and a second booster pump, thereby preventing the device from being soaked in sewage when not working.

These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
