The detector 2 includes a turbine 2-3, a Hall counter 2-4 and a TDS detection probe 2-5. The water flow passing through the detector 2 rotates the turbine 2-3. The Hall counter 2-4 counts by detecting the magnetic field change at the turbine 2-3, so as to calculate the amount of water passing through the water to be filtered. The TDS detection probe 2-5 detects the water quality of the water to be filtered. According to the detected water quality data, the amount of water passing through and the usage time of the filter element 3, it is comprehensively judged whether the filter element 3 reaches the upper limit of the service life. The comprehensive judgment of the service life here can be realized by setting a calculation formula according to the detected water quality data, the amount of water passing through and the usage time of the filter element 3. The calculation formula is preset in the manufacturer's system and will not be elaborated here. Thus, when the water quality is poor and the water volume is large, the usage time of the filter element 3 is short and the filter element replacement reminder time is early; when the water quality is good and the water volume is small, the service life of the filter element 3 is long and the filter element replacement reminder time is late.

[0018] In a further embodiment, as Figures 2-5 shown, the detector 2 further includes an NFC induction unit 2-2. The NFC induction unit 2-2 is installed inside the housing 2-8.

The phone card transmits the sensed information to the manufacturer's system to match the filter element with the after-sales record, thus ensuring after-sales service.

[0019] In a further embodiment, as Figures 2-4As shown, the detector 2 further includes a display screen 2-6, control keys 2-7, a housing 2-8, and a power plug 2-9. The water passage is integrally formed by the housing 2-8. Water inlets 2-1 and water outlets 2-10 are respectively provided at both ends of the water passage. The other ends of the water inlets 2-1 and water outlets 2-10 are respectively connected to the inlet valve 1 and the filter element 3. The water inlets 2-1 and water outlets 2-10 form a water passage inside the housing 2-8. The turbine 2-3 is installed inside the water passage of the housing 2-8, and the turbine 2-3 and the cross-section of the water passage are coaxial. The Hall counter 2-4 is installed on the outer wall of one side of the water passage. The Hall counter 2-4 is magnetically inductively connected to the turbine 2-3.

A circuit board is provided inside the detector 2. The NFC induction unit 2-2, the Hall counter 2-4, the TDS detection probe 2-5, the display screen 2-6, and the control keys 2-7 are all connected to the circuit board through wires. The power plug 2-9 and the circuit board are connected through wires.

[0020] In a further embodiment, as Figure 4 shown, a plurality of filter elements 3 are connected in series between the detector 2 and the purified water outlet valve 4 to increase the filtering capacity to adapt to an environment with worse water quality.

[0021] The power plug 2-9 is powered on, the inlet valve 1 and the purified water outlet valve 4 are opened. The TDS detection probe 2-5 detects the water quality of the water to be filtered. The water flow passes through the water passage of the detector 2. The Hall counter 2-4 detects the amount of water by the number of rotations of the turbine 2-3 and displays it on the display screen 2-6. By calculation, it is obtained the consumption of the filter element 3 and it is judged whether the filter element 3 reaches the service life. When the display screen 2-6 shows that the filter element 3 reaches the service life and needs to be replaced, the user can close the inlet valve 1 and the purified water outlet valve 4, click the control key 2-7 to confirm the filter replacement. The phone card transmits the signal to the manufacturer's system for after-sales record. Remove the filter element 3 that needs to be replaced, place the NFC induction code 3-2 of the new filter element 3 on the area of the NFC induction unit 2-2 at the bottom of the detector 2, so that the information of the new filter element is recorded in the manufacturer's system. Install the new filter element 3 to replace the old filter element 3 with the new one. It is also possible to place the NFC induction code 3-2 of the old filter element 3 on the area of the NFC induction unit 2-2 at the bottom of the detector 2, and detect whether the filter element 3 is recorded in the manufacturer through the communication connection between the phone card and the manufacturer's system, check and confirm that this filter element 3 is the manufacturer's filter element 3. Finally, open the inlet valve 1 to flush the new filter element 3. After the flushing is completed, open the purified water outlet valve 4, and the filter element 3 can be used normally.
