Description
Technical field
The invention belongs to filter core technical fields, are the sides being related to using the estimated filter element life of water quality indicator more specifically
Method and water purifier.
Background technique
It is the performance of filter core for water purifier product core.Filter core can only be in the range of the performance of setting is protected
It could use.Filter element life generally can be under conditions of water quality is bad, can maintain during filter core performance as general filter core
Life time.So the practical water that can be purified in the preferable area of water-quality ratio can be more than the guarantee service life marked on filter core,
But in the poor area of water quality, even if the water of purification is fewer than the water that filter element life marks, the performance of filter core is also possible to
It has declined, does not have the performance of filter core.
At present in water purifier industry, filter element life is calculated during being generally used accumulative use.Therefore in some areas
Filter core will be replaced in advance when filter core has not been reached yet and guarantees the service life, cause to waste；Some areas can then be marked than filter core
Guarantee just to have had reached service life critical value before the service life, because filter core degraded performance, causing cannot without replacing filter core in time
The function of purification is played, consumer drinks the water not purified.
Summary of the invention
It is existing to solve the purpose of the present invention is to provide the method and water purifier using the estimated filter element life of water quality indicator
Do not reach filter core in technology also and guarantees that replacing filter core when the service life in advance causes waste, filter core to service life critical value without timely
Replacement causes the technical issues of cannot purifying.
To achieve the above object, the technical solution adopted by the present invention is that: provide a kind of using the water quality indicator estimated filter core longevity
The method of life, comprising the following steps:
Preposition water quality sensor is installed in the front end of filter core, installs postposition water quality sensor in the rear end of filter core；
Front end water quality indicator value is obtained by the preposition water quality sensor, rear end water is obtained by the postposition water quality sensor
Matter index value；
The difference of front end water quality indicator value and rear end water quality indicator value is difference；When the difference is greater than standard value, then institute
The predicted life for stating filter core is shorter than the guarantee service life of the filter core；When the difference is less than standard value, then the filter core is pre-
It is longer than the guarantee service life of the filter core to count the service life.
Further, the range of the standard value is 0.3 ± 0.1ppm.
Further, the preposition water quality sensor and the postposition water quality sensor are for detecting COD value, TOC value
Or the water quality sensor of TDS value.
Further, the filter core is filter element of water purifier.
Further, the predicted life of the filter core, the filter core the guarantee service life and the front end water quality indicator value it
Between meet following formula:
Wherein, TexpectedFor the predicted life of filter core；TguaranteedFor the guarantee service life of filter core；It is worth on the basis of τ；Before C is
Hold water quality indicator value；γ is constant；
The predicted life of filter core is obtained by above-mentioned formula.
Further, the range of a reference value is 0.7 ± 0.1ppm.
The present invention provides a kind of water purifier, including filter core, the front end for being installed on the filter core preposition water quality sensor and
It is installed on the postposition water quality sensor of the rear end of the filter core, the water purifier is using the estimated filter core of above-mentioned use water quality indicator
The method in service life.
The present invention having the technical effect that by installing preposition water the front and rear end of filter core is corresponding compared with the existing technology
Matter sensor and postposition water quality sensor are respectively obtained the front end water of filter core by preposition water quality sensor and postposition water quality sensor
Matter index value and rear end water quality indicator value.The size of difference and standard value according to front end water quality indicator value and rear end water quality indicator value
Relationship judges filter core predicted life and guarantees the length relationship in service life.It is more quasi- according to the water quality information in installation water purifier area
True prediction filter element life.Filter core is replaced using correct predicted life as foundation, prevents filter core from wasting, and echoes country
Environment Protection Policy allows consumer to drink the water purified, improves the satisfaction of consumer.
