The first port connection of second port and first order filter, the 3rd port is connected with controller 1, for receiving controller
After the 1 backwash signal sent, shutoff operation is performed.
Entering water electromagnetic valve is arranged between running water output device and first order filter, is mainly used in controlling running water
Mobility status.When preparing pure water, entering water electromagnetic valve is in the state opened, and running water enters filter 2, carries out step by step
Filtering, and pure water is obtained, after controller 1 sends backwash signal, entering water electromagnetic valve is closed, and is no longer flow into originally in water purifier
Water, but the pure water in water storage device 3 is reversely flowed into filter 2, filter 2 is reversely rushed using pure water
Wash.
In addition, also including in cleaning device 4：First pure water backwashes magnetic valve and the second pure water backwash magnetic valve；
First pure water backwash magnetic valve first port and first order filter second port connect, second port with
The first port connection of entering water electromagnetic valve, the 3rd port is connected with controller 1；
Second pure water backwash magnetic valve first port and first order filter the 3rd port connect, second port with
Controller 1 is connected.
Because the deposit gathered in every grade of device of filter 2 is different, it is necessary to which the deposit in every grade of filter is carried out
Discharge, to avoid deposit from accumulating to again on filter.Also include in this water purifier：Blowdown apparatus, with controller 1, filtering
Device 2 and cleaning device 4 are connected, under the control of controller 1, the sewage produced after washing and filtering device 2 to be discharged.
Blowdown apparatus includes：Waste water magnetic valve, blowoff valve, the first sewage draining exit and the second sewage draining exit；
Waste water magnetic valve is connected between the 3rd port of fourth stage filter and pure water backwash magnetic valve, also, with
Controller 1 is connected；
The first port of blowoff valve is connected with the 3rd port of second level filter, and second port connects with the first sewage draining exit
Connect, the 3rd port is connected with controller 1；
The 3rd port that second sewage draining exit backwashes magnetic valve with the second pure water is connected.
Referring to Fig. 2, after the deposit of first order filter is stripped, magnetic valve is backwashed by the second pure water, by second
Sewage draining exit is discharged.After the deposit of second level filter is stripped, by blowoff valve, discharged by the first sewage draining exit, third level mistake
After the deposit of filter is stripped, after milipore filter flushing valve, discharged by the first sewage draining exit, the deposit quilt of fourth stage filter
After stripping, by waste water magnetic valve, discharged by the first sewage draining exit.
In addition, also including in the water purifier of the present embodiment：High-voltage switch gear and low tension switch, wherein：
The first port of high-voltage switch gear is connected with the second port of fourth stage filter, second port and water storage device 3

In the water purifier of the present embodiment, first order filter is 40 micro belt sewage draining exit stainless steel fore filters, the
Secondary filter is 5 micro belt sewage draining exit stainless steel filters, and third level filter is 0.01 micro belt sewage draining exit milipore filter mistake
Filter, fourth stage filter is 0.0001 micro belt sewage draining exit RO film filters.Wherein, 40 microns, 5 microns, 0.01 micron and
0.0001 micron refers to filtering accuracy.
Running water, can after first order filter, second level filter, third level filter and fourth stage filter
Running water is sufficiently filtered, suspension, bacterium and calcium ions and magnesium ions etc. are filtered, the life use for meeting and drinking is become
Water.
After water storage device water is full, cleaning device is opened the water inside pure water device, backwash fourth stage filter, the 3rd
Level filter, second level filter.Now in filters at different levels, have portion of pure water and be trapped within filter, this like
It is that filters at different levels invade bubble in pure water, because pure water plays the role of dilution, dissolving, stripping dirt, it is to avoid the silting of filter core,
Reach and exempted from the purpose for changing filter core.
Also include in the water purifier of the present embodiment：Power supply, is connected with controller 1, for being powered for controller 1.
The operation principle to water purifier as shown in Figure 2 is introduced below.
When in use, pure water is first made by filter 2, i.e. entering water electromagnetic valve is opened by controller 1, running water is by the
The first port of grade one filter is flowed into, and is sequentially passed through second level filter, third level filter and fourth stage filter and entered
Row is filtered step by step, and obtained pure water is stored in water storage device 3 (for example, Pressured water tank), is drunk for people.When filter 2
When middle deposit accumulation needs cleaning, entering water electromagnetic valve is closed by controller 1, meanwhile, backwash electromagnetism to compression pump, pure water
Valve, pure water backwash magnetic valve and milipore filter flushing valve send backwash signal, and compression pump is reverse by the pure water in water storage device 3
It is drawn into second level filter, third level filter and fourth stage filter, by the flushing of pure water, makes to be attached to the second level
After the deposit of filter is stripped, by blowoff valve, discharged by the first sewage draining exit, the deposit of third level filter is stripped
Afterwards, after milipore filter flushing valve, discharged by the first sewage draining exit, after the deposit of fourth stage filter is stripped, by Wastewater by Electric
Magnet valve, is discharged by the first sewage draining exit.Also, controller 1 sends control signal and controls the first pure water backwash magnetic valve and second
Pure water backwash magnetic valve is opened simultaneously, carries out back flush to first order filter, the deposit of first order filter is shelled
From rear, magnetic valve is backwashed by the second pure water, is discharged by the second sewage draining exit.Cleaning is finished, the control entering water electromagnetic valve of controller 1
Open, meanwhile, control pressure pump, pure water backwash magnetic valve, pure water backwash magnetic valve, milipore filter flushing valve, the first pure water
Magnetic valve and the second pure water backwash closed electromagnetic valve are backwashed, running water flows into water purification by the first port of first order filter
Machine, proceeds filtering, is drunk with obtaining pure water for people.
The embodiment has the technical effect that：By setting controller 1, filter 2, the and of water storage device 3 in water purifier
Cleaning device 4, makes water purifier while completion filtration obtains pure water, dexterously using obtained pure water to filter
2 carry out back flushes, it is to avoid the obstruction of filter 2, reduce the artificial trouble for changing filter 2.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
