Flowmeter 54.Flowmeter 54 can it is more acurrate monitoring composite filter element postposition filter core service life.Pass through high-voltage switch gear 55 and flow
The start and stop that meter 54 can control water purification system, when high-voltage switch gear 55 detects low pressure or high-voltage switch gear 55 detect high pressure and
The umber of pulse > 0 within a certain period of time of flowmeter 54 later, water purification system pure water；When high-voltage switch gear 55 detect high pressure and after
Umber of pulse is 0 to flowmeter within a certain period of time, and water purification system stops pure water processed.
The course of work of the water purification system of the present embodiment is illustrated below:
If user uses water purification: when user, which opens tap, uses water purification, raw water passes through the front filter element of composite filter element
It, can be for users to use after filtering.
If user uses pure water: when user, which opens tap, uses pure water, when high-voltage switch gear 55 detects low pressure
Or high-voltage switch gear 55 detects high pressure and umber of pulse > 0, water purification system pure water are former within a certain period of time for flowmeter 54 later
After water enters the front filter element filtering of composite filter element 10, using inlet water solenoid valve 51, stabilized pressure pump, into reverse osmosis filter core 20 into
The profound processing of row, the moisture handled through reverse osmosis filter core 20 are pure water and concentrated water.Wherein, pure water is entered multiple by check valve 53
After the postposition filter core processing for closing filter core, flowed out by flowmeter 54, high-voltage switch gear 55, the pure water of outflow can be directly connected to the fire hose
Head is for users to use；Concentrated water is discharged by waste water ratio solenoid valve 57.
When user closes tap, high-voltage switch gear 55 detects high pressure and the later pulse within a certain period of time of flowmeter 54
Number is 0, and water purification system stops pure water processed.
When water purification system water, water purification system circular flow between low rate of recovery state and high-recovery state, for example,
Low rate of recovery state runs the t1 time, and high-recovery state runs the t2 time, specific as follows:
When water purification system is run under low rate of recovery state, the power-off of waste water ratio solenoid valve 57, solenoid valves: a part of dense
Water is discharged by waste water ratio solenoid valve；Another part concentrated water is discharged by waste water ratio and solenoid valve.
After the t1 time, water purification system is run under high-recovery state, and waste water ratio solenoid valve and solenoid valve power off: one
Concentrated water is divided to be discharged by waste water ratio solenoid valve；Another part concentrated water is back to stabilized pressure pump and water inlet electricity by waste water ratio, check valve
Between magnet valve.
Water purification system enters back into low rate of recovery state operation after the t2 time, so recycles.
When rinsing, inlet water solenoid valve 51, stabilized pressure pump and waste water ratio solenoid valve 57 are powered water purification system, wash away reverse osmosis membrane
The water on surface directly passes through waste water ratio solenoid valve 57 and is discharged.

The course of work of the water purification system of the present embodiment is illustrated below:
If user uses water purification: when user, which opens tap, uses water purification, raw water passes through the front filter element of composite filter element
It, can be for users to use after filtering.
If user use pure water: when user open tap use pure water when, when high-voltage switch gear detects low pressure or
Person's high-voltage switch gear detects high pressure and umber of pulse > 0, water purification system pure water, raw water enter flowmeter within a certain period of time later
After the front filter element filtering of composite filter element 10, using inlet water solenoid valve 51, stabilized pressure pump, deep layer is carried out into reverse osmosis filter core 20
Secondary processing, the moisture handled through reverse osmosis filter core 20 are pure water and concentrated water.Wherein, pure water can be divided into two flow paths, a flow path:
Enter pressure pot by check valve 53, high-voltage switch gear 55；Another flow path: it is filtered by the postposition that check valve 53 enters composite filter element
After core processing, flowed out by flowmeter 54, the pure water of outflow can be directly connected to tap for users to use；It is pure in pressure pot
The postposition filter core that water can also enter composite filter element by high-voltage switch gear 55 is handled, and is flowed out after flowmeter 54 by tap
For users to use；Concentrated water is discharged by waste water ratio solenoid valve.
When user closes tap, high-voltage switch gear detects high pressure and umber of pulse is flowmeter within a certain period of time later
0, water purification system stops pure water processed.
When water purification system water, water purification system circular flow between low rate of recovery state and high-recovery state, for example,
Low rate of recovery state runs the t1 time, and high-recovery state runs the t2 time, specific as follows:
When water purification system is run under low rate of recovery state, the power-off of waste water ratio solenoid valve 57, solenoid valves: a part of dense
Water is discharged by waste water ratio solenoid valve；Another part concentrated water is discharged by waste water ratio and solenoid valve.
After the t1 time, water purification system is run under high-recovery state, and waste water ratio solenoid valve and solenoid valve power off: one
Concentrated water is divided to be discharged by waste water ratio solenoid valve；Another part concentrated water is back to stabilized pressure pump and water inlet electricity by waste water ratio, check valve
Between magnet valve.
Water purification system enters back into low rate of recovery state operation after the t2 time, so recycles.
When rinsing, inlet water solenoid valve 51, stabilized pressure pump and waste water ratio solenoid valve 57 are powered water purification system, wash away reverse osmosis membrane
The water on surface is directly discharged by waste water ratio solenoid valve.
Embodiment five
Fig. 5 shows the structure of the embodiment five of water purification system of the invention, the water purification system and embodiment of embodiment five
Four difference is flowmeter, in embodiment five, high-voltage switch gear 55 is only arranged, directly controls water purification system by high-voltage switch gear 55
The start and stop of system, when high-voltage switch gear 55 detects low pressure, water purification system can pure water processed；When high-voltage switch gear 55 detects high pressure
When, water purification system stops pure water processed.
Embodiment six
Fig. 6 shows the structure of the embodiment six of water purification system of the invention, the water purification system and embodiment of embodiment six
Four difference is TDS probe 58 and traffic detection function 61, and in embodiment six, TDS probe 58 is arranged in pure water pipeline 33
On, 58 real-time detection pure water TDS of TDS probe reminds user's water purifier operating status and water safety situation.
In the present embodiment, TDS probe 58 has temperature sensing package, will affect when reminding user's raw water temperature too low or too high
Reverse osmosis membrane service life and water purifier performance, need to protect water purifier.
In the present embodiment, water pipeline 35 is equipped with traffic detection function 61, and traffic detection function 61 can be more acurrate
Monitor service life and the water purification amount of composite filter element.Specifically, traffic detection function 61 is flowmeter, is easy to use.
The present invention also provides a kind of water purifier, water purifier includes: body and the water purification system that is arranged on body, water purification
System is above-mentioned water purification system.
