It is a or multiple.In present embodiment, primary processing unit 22 includes reverse osmosis membrane filter element.The aperture of reverse osmosis membrane is usually only very much
One of micron, so fine impure impurity, dissolved organic matter, bacterium etc. can not penetrate reverse osmosis membrane filter element in water.From
And reverse osmosis membrane filter element detaches pure water and other impurities, is further flowed into positioned at main mistake through the pure water of reverse osmosis membrane filter element
The rear filter device 23 in device 22 downstream is filtered, and includes the concentrated water then wastewater discharge pipe by being connect with primary processing unit of impurity
Road 14 is discharged.Postpositive disposal device 23 generally comprises activated carbon cartridge, is used for the pH value of adjusting water outlet, improves mouthfeel.It needs
It is bright, in other embodiments, pretreatment unit 21 and after-treatment device 23 not necessarily, or outside purifier
Existing arrangement in water route, it is possible to save.
It is additionally provided with a supercharging device 31 between pretreatment unit 21 and primary processing unit 22, is in the present embodiment increasing
Press pump arrives 8Kg/cm2, to enable the hydrone in the raw water of high pressure to penetrate master for the pressure of raw water to be increased to 5
Reverse osmosis filter core in processing unit 22.Purifier 100 further includes a return line 13, and both ends connect with main water pipeline
Logical, first end 131 is set to the downstream of primary processing unit 22, and second end 132 is then set to the upstream of supercharging device 32, uses
Main place is returned in making to handle obtained purified water (be in present embodiment capable of direct drinking pure water) by primary processing unit 22
The upstream for managing device 22, to carry out the process of water processed again.In present embodiment, the setting of first end 131 of return line 13 exists
On the water purification outlet pipeline 12 of 23 rear end of after-treatment device.Preferably, a check valve 135 is equipped on return line 13,
Water (flow) direction for limiting in return line 13 can only be from first end 131 to second end 132.
Purifier 100 further includes in the main waterway being arranged between pretreatment unit 21 and supercharging device 32 into water power
Magnet valve 31, the water solenoid valve 34 being arranged on water purification outlet pipeline 12, the waste water electromagnetism being arranged on discharge of wastewater pipeline 14
Valve 33 or waste water ratio.One controller 40 and above-mentioned entering water electromagnetic valve 31, water solenoid valve 34, waste water solenoid valve 33 and supercharging
Device 32 is electrically connected.The controller 40 can be the logic control being formed by connecting according to certain wire laying mode by several electronic components
Circuit processed；It can also be the microcontroller (MCU) of instruction of having program stored therein；The either integrated chip with proprietary purposes, such as
Field programmable gate array (Field-Programmable Gate Array, FPGA) etc..
After the water solenoid valve 34 on water purification outlet pipeline 12 is closed, controller 40 can be by pipeline
TDS (Total Dissolved Solids, total dissolved solid substance) sensors detect the water quality in main water pipeline, or
The hydraulic pressure in main water pipeline is detected by the pressure sensor in pipeline, or water solenoid valve 34 is counted by timing and is continued
The time of closing.When the parameter of above-mentioned acquisition is more than preset threshold value, controller 40 opens supercharging device 32 and works, from
And the purified water in water purification outlet pipeline 12 can return to the front end of primary processing unit 22 by return line 14, and with the original in this place
Water mixes, and mixed water becomes purified water again after being handled by primary processing unit 22, meanwhile, the concentrated water/waste water separated
It is discharged by discharge of wastewater pipeline 14.In this way, the bacterium grown in pipeline due to being not used for a long time can be filtered
It removes, also, purified water is mixed to form the water of low concentration with raw water, effectively can reduce influent concentration and make in winner's filter device 22
Filter core rinse it is more abundant, in addition, compared to can all reduce the consumption of water by purified water filter cartridge flushing.
Shown in Fig. 2 is the another embodiment of the utility model purifier.In present embodiment, purifier
200 water purification outlet pipeline includes the cold water purification outlet pipeline 121 being arranged in parallel and hot water purification outlet pipeline 122.Purifier
200 further include the flow regulator 36 being arranged in hot water purification outlet pipeline 122 and heating device 37.Heating device 37 can be with
It is powerful electrically heated rod, for being heated the purified water being discharged by clear water faucet 90 immediately.Flow-rate adjustment fills
36 are set to be arranged in the upstream of heating device 37, for limiting the flow of purified water to be heated, to avoid flow it is excessive and can not
It is heated to set temperature.Flow regulator 36 can in a preferred embodiment, be flowed by motor-driven control valve
Quantity regulating device can also be integrated with flowmeter and check valve.Water solenoid valve 34 be arranged in cold water purification outlet pipeline 121 with
For controlling the water purification flowed in the pipeline.It is additionally provided in hot water purification outlet pipeline 122 for controlling water purification stream in the pipeline
Dynamic another water solenoid valve 35.Two water solenoid valves 34,35 and flow regulator 36, heating device 37 with
Controller 40 is electrically connected.
In present embodiment, being located at the check valve 136 on return line has minimum Opening pressure, such as 2.5Kg/cm2.
That is when the hydraulic pressure in return line 13 is less than 2.5Kg/cm2, check valve not only acts as non-return effect, also acts as and cuts
Effect only；And when the hydraulic pressure in return line 13 meets or exceeds 2.5Kg/cm2, check valve 136 is opened.In this process
In, check valve is equivalent to a hydraulic control device.
Clear water faucet 90 is opened, and when needing the water purification of heat outputting, supercharging device 32 works, at the same time, flow-rate adjustment dress
Set 36 and heating device 37 also work.Due to the supercharging of supercharging device 32 and the current limliting of flow regulator 36 so that main place
The hydraulic pressure managed in the pipeline of 22 downstream of device and 36 upstream of flow regulator rises.If hydraulic pressure is excessively high, generated in pipeline
It builds the pressure, the service life of reverse osmosis membrane and filter effect can be impacted, while as pressure change causes the water purification of heat
Leaving water temperature control is inaccurate.Due to being provided with the check valve 136 with minimum Opening pressure in return line 13, work as reflux
Hydraulic pressure between the first end 131 of pipeline and the check valve 136 reaches predetermined value, i.e., minimum Opening pressure when, check valve 136 is beaten
It opens, at this point, would not be further continued for rising positioned at the hydraulic pressure of 36 upstream portion of flow regulator in water purification outlet pipeline and be more than
The predetermined value to avoid being impacted to reverse osmosis membrane due to hypertonia, and then ensures that effluent quality reaches healthy mark
Standard, while ensureing that leaving water temperature is precisely controlled.
