Still the case where being on active service and purifying property caused to decline, or can be replaced to avoid the filter core for not arriving end of lifetime and cause to provide
The case where source wastes.
Below with reference to the accompanying drawings the filter element life monitoring method, device and air cleaning facility of the embodiment of the present application are described.
Fig. 1 is the flow diagram of filter element life monitoring method provided by the embodiment of the present application one.
The embodiment of the present application be configured in filter element life monitoring device with the filter element life monitoring method come for example,
The filter element life monitoring device can be applied in air cleaning facility, so that the air cleaning facility executes filter element life monitoring
Function.Wherein, air cleaning facility refers to the relevant device with air-cleaning function, such as can be air purifier, air-conditioning
Etc. equipment.
In the embodiment of the present application, filter core is for decomposing polluter to obtain target substance.
It is understood that utilizing air for solid pollutant (such as pellet PM10, PM2.5 etc.)
When cleaning equipment is filtered it, mainly it is adsorbed using filter core, to achieve the purpose that purify air, and for gas
Body pollution object (such as formaldehyde, total volatile organism (Total Volatile Organic Compounds, abbreviation TVOC)
Deng), can use filter core decomposes it, to obtain target substance.
Therefore, in the embodiment of the present application, polluter is specifically as follows gas pollutant, such as formaldehyde, volatility containing chlorine
Organic matter (Cl-VOCs) etc..Filter core can decompose polluter, obtain target substance, for example, filter core can be right
Formaldehyde is decomposed, and carbon dioxide CO is obtained2With water H20, at this point, target substance can be carbon dioxide, alternatively, filter core can be with
Volatile organic matter containing chlorine is decomposed, carbon dioxide CO is obtained2, water H20 and other substances, at this point, target substance can also
Think carbon dioxide.
As shown in Figure 1, the filter element life monitoring method the following steps are included:
Step 101, it is carried out in air purification process using filter core, the concentration of monitoring objective substance.
In the embodiment of the present application, after user opens air cleaning facility, air can be purified using filter core, this
When, filter core can decompose polluter, obtain target substance.In air purification process, related transducer can be used
Device detects the concentration of target substance.
For example, can use the concentration of carbon dioxide sensor detection target substance when target substance is carbon dioxide.
Step 102, according to the concentration of the target substance monitored, filter element life is determined.
It is understood that within a preset period of time, if the concentration of target substance rises obviously, showing what filter core decomposed
Polluter is more, and the detergent power of air cleaning facility is stronger, at this point it is possible to determine the non-end of lifetime of filter element life, and if
Significant change does not occur for the concentration of target substance, or does not change, then the polluter for showing that filter core decomposes is less, or

Therefore, in the embodiment of the present application, filter element life can be determined according to the concentration of the target substance monitored.For example,
Can be according in preset time period, the concentration variable quantity of target substance determines filter element life, alternatively, can be according to the unit time
The concentration variable quantity of interior target substance, determines filter element life, with no restriction to this.Thus, it is possible to filter element life is accurately identified,
So as to avoiding not identifying correctly relevant issues caused by filter element life, for example, can to avoid end of lifetime filter core still
The case where being on active service and purifying property caused to decline, or can be to avoid the filter core for not arriving end of lifetime is replaced and causes resource unrestrained
The case where taking.
It should be noted that, although related sensor can be used, the concentration of polluter is directly detected, according to pollutant
The concentration of matter determines the chip service life, for example, concentration of formaldehyde can be detected by formaldehyde sensor when polluter is formaldehyde,
If in preset time period, concentration of formaldehyde decline is obvious, at this point it is possible to determine that the clean-up effect of air cleaning facility is preferable, in turn
Determine the non-end of lifetime of filter element life.But the service life of formaldehyde sensor is shorter, if being arranged formaldehyde sensor in air cleaning
In equipment, frequency is needed to change replacement formaldehyde sensor, such as the PARA FORMALDEHYDE PRILLS(91,95) sensor of half a year or 1 year is replaced, higher cost.
And in the embodiment of the present application, according to the concentration of the target substance decomposed to polluter, determine chip
Service life, for example, when target substance be carbon dioxide when, carbon dioxide sensor lasts a long time, it is therefore not necessary to carry out to it
Frequently replacement, can reduce cost.Also, the concentration that target substance is detected by related sensor, according to the dense of target substance
Degree, determines filter element life, caused by the immature technology that reference can also be avoided additional situations such as risk.
The filter element life monitoring method of the embodiment of the present application, by being carried out in air purification process using filter core, monitoring
The concentration of target substance, and according to the concentration of the target substance monitored, determine filter element life, wherein target substance is filter core
Polluter is decomposed.In the application, according to the concentration of target substance, can determine filter core detergent power and
Clean-up effect, and then according to detergent power or clean-up effect, filter element life can be determined, thus, it is possible to accurately identify the filter core longevity
Life, so as to avoid not identifying correctly relevant issues caused by filter element life, such as can be to avoid the filter core of end of lifetime
Still the case where being on active service and purifying property caused to decline, or can be replaced to avoid the filter core for not arriving end of lifetime and cause to provide
The case where source wastes.
As a kind of possible implementation, target of the available air cleaning facility before air purification process starts
The concentration of substance, and the concentration of the preset time period target substance after air purification process starts is obtained, by according to two
The concentration difference for the target substance that time point monitors, determines filter element life.Below with reference to Fig. 2, the above process is carried out detailed
Explanation.
Fig. 2 is the flow diagram of filter element life detecting method provided by the embodiment of the present application two.
As shown in Fig. 2, step 102 can specifically include following sub-step on the basis of embodiment shown in Fig. 1:
Step 201, the concentration of target substance before air purification process starts is obtained.
In the embodiment of the present application, before air purification process starts, refer to that filter core does not purify air, i.e., filter core is to sky
Before gas is purified.The concentration of target substance before air purification process starts can be detected by related sensor.
For example, can after air cleaning facility unlatching, when user does not trigger purification function, through related sensor,
Detect the concentration of target substance.Specifically, when user by touch air cleaning facility virtual key or physical button, open
After dynamic air cleaning facility, alternatively, when user by controlled on mobile terminal electrical equipment application program (Application,
Abbreviation APP), after starting air cleaning facility, also, when user does not trigger purification function, at this point, air cleaning facility is in
Before air purification process starts, the concentration of target substance, such as label air purification process can be detected by related sensor
The concentration of target substance is C1 before starting.
Wherein, mobile terminal can be the tool such as mobile phone, tablet computer, personal digital assistant, wearable device, mobile unit
There is the hardware device of various operating systems, touch screen and/or display screen.
Step 202, concentration difference is calculated, concentration difference is the preset time period target substance after air purification process starts
Concentration and air purification process start before target substance concentration between concentration difference.
In the embodiment of the present application, preset time period is pre-set, such as can be the built-in journey of air cleaning facility
Sequence is pre-set, or can also be configured by user, with no restriction to this, such as preset time period can for 30min,
1h etc..Air purification process start after preset time period, after referring to that air cleaning facility is opened, filter core carries out air net
Preset time period after change, such as filter core carry out purified 30min to air.
In the embodiment of the present application, preset time period after air purification process starts, such as air cleaning facility are opened
Afterwards, filter core carries out purified 30min to air, the concentration of target substance can be acquired by related sensor, such as mark
The concentration of preset time period target substance after air purification process starts is C2, and it is poor that C2 and C1 are made, and obtains air cleaning
Journey start after preset time period target substance concentration and air purification process start before target substance concentration between it is dense
Spending difference is | C2-C1 |.As a result, after air purification process starts, the target for acquiring related sensor in real time may be implemented
The concentration of substance, the concentration of target substance is compared before starting with air purification process, to determine the service life of filter core, Ke Yiti
Rise the accuracy that filter element life determines in subsequent step.
Step 203, according to concentration difference, filter element life is determined.
It is understood that purifying property is preferable when filter element life non-end of lifetime, with the growth of time, divide
The target substance that solution obtains is more and more, air cleaning facility target substance in space concentration it is also higher and higher.Cause
This, a kind of possible implementation as the embodiment of the present application, it can be determined that concentration difference | C2-C1 | whether it is lower than the first threshold
Value, if so, determining that filter element life is end of lifetime, if not, it is determined that the non-end of lifetime of filter element life.Wherein, first threshold
It is pre-set, such as can be pre-set for the plug-in of air cleaning facility, alternatively, can also be carried out by user
Setting, with no restriction to this.
It should be noted where the air cleaning facility space not simultaneously as space size difference, environment temperature,
The external factors such as humidity difference may cause filter core under same purification efficiency, and the concentration of the target substance measured exists
Significant change, for example, the volume of space A is less than space B, it is assumed that the obtained target substance that filter core is decomposed in space A, with filter
The target substance that core decomposes in space B as many, since the volume of space A is less than space B, the then target in the A of space
The concentration of substance is greater than the concentration of the target substance in space B, therefore, according to concentration difference | C2-C1 | whether it is lower than the first threshold
Value, to judge filter element life, may influence the accuracy of judging result.
Therefore, can be according to concentration difference as the alternatively possible implementation of the embodiment of the present application | C2-C1 | meter
It calculates growth factor and filter element life is determined according to growth factor.Specifically, can be by concentration difference | C2-C1 | with air cleaning
The concentration C 1 of target substance does ratio before journey starts, and obtains growth factor.Due to continuing on with filter core, detergent power by
Decrescence weak, growth factor is ever-reduced, therefore, it is possible to judge that whether growth factor is lower than third threshold value, if so, showing
The detergent power of filter core is weaker, at this point it is possible to determine that filter element life is end of lifetime, if not, it is determined that the filter element life non-service life
Latter stage.Wherein, third threshold value is pre-set, such as can be pre-set for the plug-in of air cleaning facility, or
Person can also be configured, with no restriction to this by user.
It, can also be according to growth factor and preset ginseng as another possible implementation of the embodiment of the present application
Growth factor is examined, determines filter element life.
As a kind of possible implementation, growth factor and the first attenuation amplitude with reference to growth factor can be calculated,
For example, label growth factor is S1, and it is S2 with reference to growth factor, the first attenuation amplitude is D1, then S1=| C2-C1 |/C1, D1=
| S1-S2 |/S2, then, it can be determined that whether the first attenuation amplitude D1 is higher than the 4th threshold value, if so, showing the purification of filter core
Effect decaying is obvious, and detergent power is weaker, at this point it is possible to determine that filter element life is end of lifetime, if not, it is determined that filter element life
Non- end of lifetime.
As alternatively possible implementation, growth factor S1 can also be judged and with reference to the difference between growth factor S2
Value | S2-S1 | whether it is lower than the 5th threshold value, if so, showing that the detergent power of filter core is weaker, at this point it is possible to determine filter element life
For end of lifetime, if not, it is determined that the non-end of lifetime of filter element life.
Wherein, the 4th threshold value and the 5th threshold value are pre-set, such as can be the plug-in of air cleaning facility
It is pre-set, alternatively, can also be configured by user, with no restriction to this.
For example, using polluter as formaldehyde, target substance CO2Example, it is assumed that after air cleaning facility starting, room
Interior CO2Concentration is 400ppm, after ten minutes, indoor CO2Concentration is 420ppm, then growth factor S1=| 420-400 |/400
=0.05, it is assumed that refer to growth factor S2=0.125, the 4th threshold value is 50%, then D1=| 0.05-0.125 |/0.125=
60% > 50%, hence, it can be determined that filter core is obvious except the decaying of aldehyde effect, filter element life is end of lifetime.
It should be noted that it is above-mentioned only with reference to growth factor for pre-set example, when practical application, it is contemplated that when
When being preset with reference to the plug-in that growth factor is air cleaning facility, value and the calibration environmental correclation before factory, such as
Space size difference, environment temperature, humidity difference etc., may cause the corresponding reference growth factor of different spaces, there are biggish
Difference, to influence the accuracy of filter element life judging result, therefore, in the application, available use for the first time is supervised when filter core
The concentration of the target substance measured, and determine for the first time using the concentration difference in unit time when filter core, according in the unit time
Concentration difference determine refer to growth factor.Specifically, can by for the first time use filter core when the unit time in concentration difference with
The concentration of the target substance monitored when for the first time using filter core does ratio, obtains with reference to growth factor.
Further, when filter element life is end of lifetime, user can be prompted, to remind user to replace filter
Core, such as voice broadcast can be carried out by air cleaning facility, alternatively, the control electrical equipment on mobile terminal can be passed through
APP to user send prompt information, with no restriction to this.And when the non-end of lifetime of filter element life, it can continue to monitor mesh
The concentration of substance is marked, to carry out real-time monitoring to filter element life, that is, returns and re-execute the steps 202 and subsequent step.
The filter element life monitoring method of the embodiment of the present application, can by the clean-up effect or detergent power according to filter core,
It determines filter element life, the accuracy of filter element life definitive result can be promoted.
It, can also be according to the concentration variable quantity of the target substance in the unit time, really as a kind of possible implementation
Determine filter element life.Below with reference to Fig. 3, the above process is described in detail.
Fig. 3 is the flow diagram of filter element life monitoring method provided by the embodiment of the present application three.
As shown in figure 3, step 102 can specifically include following sub-step on the basis of embodiment shown in Fig. 1:
Step 301, according to the concentration of the target substance monitored, the concentration variable quantity in the unit time is determined.
In the embodiment of the present application, the unit time is pre-set, such as can be 1min, 10min etc..Concentration variation
Amount can be the absolute change amount of concentration, or, or the relative variation of concentration, with no restriction to this.For example, label
Concentration variable quantity is T0, and the concentration for the target substance that label previous moment detects is C3, the target that current time detects
The concentration of substance is C4, then the absolute change amount of concentration is T0=| C4-C3 |, the relative variation of concentration is T0=| C4-C3 |/
C3。
Step 302, according to concentration variable quantity, filter element life is determined.
It is understood that purifying property is preferable when filter element life non-end of lifetime, with the growth of time, divide
The target substance that solution obtains is more and more, air cleaning facility target substance in space concentration it is also higher and higher.Cause
This can determine the non-end of lifetime of filter element life when the concentration variable quantity in the unit time is higher, and when in the unit time
When concentration variable quantity is lower, it can determine that filter element life is end of lifetime.
As a kind of possible implementation, it can be determined that whether concentration variable quantity is lower than the 6th threshold value, if so, showing
The detergent power of filter core is weaker, at this point it is possible to determine that filter element life is end of lifetime, if not, it is determined that the filter element life non-service life
Latter stage.Wherein, the 6th threshold value is pre-set, such as can be pre-set for the plug-in of air cleaning facility, or
Person can also be configured, with no restriction to this by user.
The filter element life monitoring method of the embodiment of the present application, by determining filter according to the concentration variable quantity in the unit time
The core service life can equally promote the accuracy of definitive result.
As alternatively possible implementation, a reference concentration variable quantity can also be set, and calculates concentration variation
Concentration variable quantity difference between amount and reference concentration variable quantity determines filter element life according to concentration variable quantity difference.Below with reference to
The above process is described in detail in Fig. 4.
Fig. 4 is the flow diagram of filter element life monitoring method provided by the embodiment of the present application four.
As shown in figure 4, step 302 can specifically include following sub-step on the basis of embodiment shown in Fig. 3:
Step 401, to concentration variable quantity, the concentration variable quantity difference between the reference concentration variable quantity of setting is calculated.
As a kind of possible implementation of the embodiment of the present application, reference concentration variable quantity can be pre-set,
Such as labeled as T1, then the concentration variable quantity difference between the concentration variable quantity T0 in the unit time and reference concentration variable quantity T1
For | T1-T0 |.
It should be noted that it is above-mentioned only with reference concentration variable quantity for pre-set example, when practical application, it is contemplated that
When the plug-in that reference concentration variable quantity is air cleaning facility is preset, value and the calibration environment phase before factory
It closes, such as space size difference, environment temperature and humidity difference, may cause the corresponding reference concentration variable quantity of different spaces and exist
Biggish difference, to influence the accuracy of filter element life judging result.Therefore, as the alternatively possible of the embodiment of the present application
Implementation, it is available for the first time using filter core when the concentration C 0 that monitors, and determine unit time when using filter core for the first time
Interior concentration variable quantity, then, according to the concentration variable quantity in unit time when using filter core for the first time, setting reference concentration changes
Measure T1.
Step 402, according to concentration variable quantity difference, filter element life is determined.
It is understood that purifying property is preferable when filter element life non-end of lifetime, with the growth of time, divide
The target substance that solution obtains is more and more, air cleaning facility target substance in space concentration it is also higher and higher.Cause
This, a kind of possible implementation as the embodiment of the present application, it can be determined that concentration variable quantity difference | T1-T0 | whether it is lower than
Second threshold, if so, determining that filter element life is end of lifetime, if not, it is determined that the non-end of lifetime of filter element life.Wherein,
Two threshold values be it is pre-set, such as can for air cleaning facility plug-in it is pre-set, alternatively, can also by with
Family is configured, with no restriction to this.
It should be noted that space is not simultaneously as space size difference, environment temperature be wet where air cleaning facility
The external factors such as difference are spent, can cause filter core under same purification efficiency, the concentration of the target substance measured exists aobvious
The variation of work, for example, the volume of space A is less than space B, it is assumed that the obtained target substance that filter core is decomposed in space A, with filter core
The target substance decomposed in space B, since the volume of space A is less than space B, then the target substance in the A of space is dense
Degree is greater than the concentration of the target substance in space B, therefore, according to concentration variable quantity difference | T1-T0 | whether it is lower than second threshold,
Judge filter element life, may influence the accuracy of judging result.
It therefore, can also be according to dense in the unit time as the alternatively possible implementation of the embodiment of the present application
Variable quantity T0 is spent, real-time growth factor is calculated, according to real-time growth factor, determines filter element life.Specifically, label increases in real time
Coefficient U1, then U1=T0/C3=| C4-C3 |/C3, due to continuing on with filter core, detergent power gradually weakens, and increases system
Number is ever-reduced, therefore, it is possible to judge that whether growth factor U1 is lower than the 7th threshold value in real time, if so, showing filter core
Detergent power is weaker, at this point it is possible to determine that filter element life is end of lifetime, if not, it is determined that the non-end of lifetime of filter element life.
Wherein, the 7th threshold value is pre-set, for example, can preset for the plug-in of air cleaning facility
, alternatively, can also be configured by user, with no restriction to this.
It, can also be according to real-time growth factor and reference as another possible implementation of the embodiment of the present application
Concentration growth factor, determines filter element life.Wherein, reference concentration growth factor can be pre-set, can also be according to ginseng
It examines concentration variable quantity T1 to determine, for example label reference concentration growth factor is U2, then U2=T1/C0.
As a kind of possible implementation, it can be determined that between real-time growth factor U1 and reference concentration growth factor U2
Difference | U2-U1 | whether be lower than the 8th threshold value, if so, show that the detergent power of filter core is weaker, at this point it is possible to determine filter core
Service life is end of lifetime, if not, it is determined that the non-end of lifetime of filter element life.
As alternatively possible implementation, real-time growth factor U1 and reference concentration growth factor U2 can also be calculated
Between the second attenuation amplitude, such as the second attenuation amplitude of label is D2, then D2=| U2-U1 |/U2, then, it can be determined that the
Whether two attenuation amplitudes are higher than the 9th threshold value, if so, showing that the clean-up effect decaying of filter core is obvious, detergent power is weaker, this
When, it can determine that filter element life is end of lifetime, if not, it is determined that the non-end of lifetime of filter element life.
Wherein, the 8th threshold value and the 9th threshold value are pre-set, such as can be the plug-in of air cleaning facility
It is pre-set, alternatively, can also be configured by user, with no restriction to this.
For example, it is assumed that the 9th threshold value is 50%, for the first time using filter core when the concentration C 0 that monitors be 400ppm, in list
The concentration got after the time Δ T of position is 450ppm, then reference concentration growth factor U2=(450-400)/400=0.125, when
The concentration C 4 for the target substance that the preceding moment detects is 420ppm, and the concentration C 3 for the target substance that previous moment detects is
400ppm, then real-time growth factor U1=(420-400)/400=0.05, the second attenuation amplitude D2=| 0.05-0.125 |/
0.125=60% > 50%, hence, it can be determined that filter core is obvious except the decaying of aldehyde effect, filter element life is end of lifetime, at this point, can
To remind user to replace filter core, the case where filter core to avoid end of lifetime is still on active service and purifying property is caused to decline, improves
The usage experience of user.
It should be noted that above-mentioned first threshold, second threshold ..., the 8th threshold value, the value of the 9th threshold value can phase
Together, it can also be different, with no restriction to this.
In order to realize above-described embodiment, the application also proposes a kind of filter element life monitoring device.
Fig. 5 is the structural schematic diagram of filter element life monitoring device provided by the embodiment of the present application five.
In the embodiment of the present application, filter core is for decomposing polluter to obtain target substance.
As shown in figure 5, the filter element life monitoring device includes: monitoring modular 101 and determining module 102.
Wherein, monitoring modular 101, for being carried out in air purification process using filter core, the concentration of monitoring objective substance.
As a kind of possible implementation, filter core can be except formaldehyde filter core, at this point, target substance can be carbon dioxide.
