Technical field
The present invention relates to purifier technical field is and in particular to a kind of purifier and its pressure differential method judge that filter element uses
The method in life-span.
Background technology
It is known that water purifier market is it is crucial that carry out service, and service to the effect that provide the user filter
Service changed by core；The replacing of each filter element of water purifier has important meaning to whole machine effluent quality and longtime running reliability in time
Justice；Will result in crucial filter element such as reverse osmosiss filter element and block in advance as preprocessing filter element is changed not in time；The blocking of reverse osmosiss filter element will
Booster pump is made to be in stall working condition, very big to the aging effects of whole machine waterway seal and pump.When however, filter element
Can it be the most reasonable to change, judge the replacing date of filter element exactly, and then sends prompting or automatically notify service centre, to user
Carry out maximally effective filter element replacing service, these are all the problems of water purification industry joint research.
The method of existing estimation filter element life is it is common that pass through to calculate the use time of water purifier and the water total amount of user
To judge, when filter element use time exceedes setting value, or when the filtration water yield of filter element reaches setting value, to be judged as filter element life
Arrive, send prompting changing filter element.
However, the method for above-mentioned estimation filter element life, judge filter element service life with fixing preset value hence it is evident that being forbidden
Really；Because each department source quality situation varies, the filter element service life of the environment of different quality also accordingly differs greatly,
Do not enable the accurate judgement of filter element life with fixing computational methods.The area good to water quality, filter element degree of injury is also
Very little is just changed, and causes to waste；And the very poor area of water quality, filter element replacing remind have not arrived, filter element has just blocked, causes
User fails to change filter element in time and cannot use water, causes customer complaint.
Content of the invention
It is an object of the invention to overcoming the shortcomings of that above-mentioned prior art exists, and one kind is provided to enter by detecting each filter element
Pressure difference value between the mouth of a river and outlet, judges the stopping state of filter element, and then accurately judges filter element service life, to use

Pressure value, and pressure value is sent to panel, the real-time pressure between water inlet and outlet is calculated by panel
Difference, and judge whether real-time pressure difference meets or exceeds the filter element service life limit, and send alerting signal；Such water purification
Device, by the filter element water inlet in water route and outlet, sets up pressure transducer and gathers its pressure value, and coordinate panel
Default filter element service life limiting figure, by calculating the real-time pressure amount difference between water inlet and outlet, you can sentence
Whether disconnected real-time pressure difference meets or exceeds the filter element service life limit, judges the stopping state of filter element, and then accurate judgement
Filter element service life, to send alerting signal, so that user changes.
Further, it can also include alerting signal device, and alerting signal device is electrically connected with panel, by carrying
Awake advertiser sends filter element life alerting signal.
Further, described alerting signal device can be display screen or signal lighties alarm or voice guard, so that
User obtains alarm in time.
Further, the water inlet of described same filter element and outlet are respectively arranged with an independent pressure transducer,
Two pressure transducers are electrically connected with panel respectively；That is, using the pressure transducer of traditional single point pressure detection.
Further, the water inlet of described same filter element and outlet are provided with an independent pressure transducer, and this is only
Vertical pressure transducer is the pressure transducer with two water inlets, two water inlets be connected to filter element water inlet and
Outlet；I.e.：Using 2 points of pressure transducers that even more multipoint pressure detects, to simplify its overall structure, install simpler.
Further, described filter element includes PP cotton on purifier water route, activated carbon and RO reverse osmosis filter membrane, filters at different levels
Each port of core is respectively arranged with described pressure transducer.
The purpose of the present invention can also adopt another embodiment：
A kind of method that pressure differential method as above-mentioned purifier judges filter element service life, is characterized in that, comprise the steps：
Step one：Panel presets a certain pressure difference value as the filter element service life limit, standby；
Step 2：The pressure transducer collection water inlet of filter element and the pressure value of outlet, and pressure value is sent to control
Making sheet；
Step 3：Panel receives the pressure value of above-mentioned water inlet and outlet, and calculates between water inlet and outlet
Real-time pressure difference, judges whether real-time pressure difference meets or exceeds the filter element service life limit of step one, and sends and carry
Awake signal.
The method that this pressure differential method judges filter element service life, enforcement is easy for it, accurately judge that the filter element of purifier makes
With the life-span, make purifier not be subject to regional water quality Different Effects, can accurately detect the actual life of filter element.
Further, a certain pressure difference value that described step one panel presets the filter element service life limit is P value, controls
When the pressure difference value that plate calculates is equal to or more than P value, alerting signal can be sent.
Further, the alerting signal that described step 3 sends is shown by display screen by alerting signal device, signal lighties
Alarm or voice guard send corresponding signal and remind.
Beneficial effects of the present invention are as follows：
