Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
Embodiment one
An embodiment of the present invention provides a kind of strainer service life to determine method.Fig. 1 is that the strainer service life of the embodiment of the present invention is true
Determine the flow diagram of method；As shown in Figure 1, the method includes：
Step 101：Every preset time period detection obtains the pollutant concentration of local environment, obtains the air purifier
The strainer filtering efficiency of interior wind speed, the acquisition air purifier.
Step 102：The pollutant concentration, the wind speed and the strainer filtering obtained based on the preset time period
Efficiency determines dust containing capacity.
Step 103：Acquisition is summed up to the dust containing capacity that all preset time periods obtain and adds up dust containing capacity.
Step 104：The remaining life of the strainer of the air purifier is determined based on the accumulative dust containing capacity.
The technical solution of the embodiment of the present invention is applied in air purifier, and the building block of air purifier can mainly wrap
It includes：Protecgulum, strainer, motor, rear cover, wherein air inlet is provided on protecgulum, after cover and be provided with air outlet, motor effect and
The distinguished and admirable of generation flows to air outlet by air inlet across strainer, in this way, the wind in air outlet outflow is exactly cleaned by strainer
Wind.Certainly, air purifier can also have more components to realize more abundant function, for example, in strainer and motor
Between be provided with for adsorbing fine particle and the high molecular high performance material of peculiar smell and absorbent charcoal material, be also provided with use
In the TiO for taste smoke elimination of dispelling2Layer and ultraviolet lamp etc. for taste sterilization of dispelling.
In the embodiment of the present invention, the type of the strainer of air purifier is not limited, and strainer can be particulate matter strainer,
It can also be organic matter strainer.Wherein, particulate matter strainer is divided into slightly to imitate strainer and fine particle strainer；Organic matter strainer is divided into
Except formaldehyde strainer, deodorization strainer, active carbon filter screen, super smooth mineralising strainer etc..Each strainer mainly for pollution sources
It is different from, the principle of filtering also differs.
In the embodiment of the present invention, every preset time period detection obtains the pollutant concentration of local environment, obtains the sky
The strainer filtering efficiency of wind speed, the acquisition air purifier in gas purifier.Wherein, adjacent to obtain local environment twice
The period of wind speed, strainer filtering efficiency in pollutant concentration, air purifier can be identical or differs, specifically can be according to reality
Border situation is preset.For example, the period that fixed size can be arranged carries out data acquisition.In another example can be with air purification
Device uses duration, the period of setting to be in shortening trend, it will be understood that with the remaining life of the strainer of air purifier
Shortening, preset time period also shortens, also allows for that strainer remaining life is made more to level off to actual life in this way.
Wherein, the every preset time period detection obtains the pollutant concentration of local environment, including：Every preset time
Section obtains the pollutant concentration of local environment by pollutant monitoring sensor；The pollutant monitoring sensor may be disposed at sky
The air inlet of gas purifier, or may also set up in strainer towards air inlet direction, to obtain ring residing for air purifier
The pollutant concentration in border.
As an implementation, the wind speed obtained in the air purifier, including：Obtain the air purification
The rotating speed of the motor of device determines the wind speed in the air purifier based on the rotating speed；Alternatively, passing through the air purifier
The wind speed measurement component of setting obtains the wind speed in the air purifier.Wherein, as an implementation, the rotation of motor
Air flowing is driven, to generate wind, it will be understood that the rotating speed of motor has correspondence with wind speed；Air purifier stores
The correspondence for having rotating speed and wind speed can obtain wind speed after the rotating speed for obtaining motor by inquiring the correspondence.As
Another embodiment can also dispose wind speed measurement component, such as airspeedometer (anemobiagraph) in air purifier, be examined by wind speed
It surveys component and obtains wind speed.
As another embodiment, the wind speed obtained in the air purifier, including：When based on current preset
Between the previously obtained first accumulative dust containing capacity of section and the second preset function obtain the wind speed in the air purifier.
Specifically, in practical applications, along with the increase of the accumulative dust containing capacity of strainer, strainer is more next to the obstruction of air-flow
It is bigger, the rotating speed of the motor of air purifier and the wind speed and the rigorous correspondence of non-exhibiting in the air purifier,
Wind speed corresponding with motor rotating speed that is being obtained in former embodiment is often inaccurate, and actual wind speed can become smaller.
Based on this, in present embodiment, the relationship for adding up dust containing capacity and wind speed is indicated by the second preset function, can specifically pass through second
Preset function determines wind speed.Wherein, the wind speed V(NT)It is represented by：

The area of the strainer carries out product, obtains the dust containing capacity.Further, the dust containing capacity obtained to each period adds
And processing, to obtain accumulative dust containing capacity of the strainer from beginning to use current time.Specifically, the accumulative dust containing capacity M(NT)
Meet：
Wherein, X(NT)Indicate pollutant concentration；V(NT)It is expressed as wind speed；f(NT)It is expressed as strainer filtering efficiency；S is expressed as
The area of strainer；The area of strainer can be pre-configured with storage.
In the embodiment of the present invention, the remaining longevity of the strainer that the air purifier is determined based on the accumulative dust containing capacity
Life, including：Default accumulative dust containing capacity threshold value is compared with the accumulative dust containing capacity and obtains the first ratio；Based on described first
Ratio and default lifetime threshold determine the remaining life of the strainer of the air purifier.
Specifically, in practical application, it can be pre-configured with accumulative dust containing capacity threshold value, which shows strainer energy
The maximum dust containing capacity enough born；Correspondingly, the maximum dust containing capacity corresponds to the maximum life of strainer.Then the different periods is counted
The accumulative dust containing capacity calculated is compared in accumulative dust containing capacity and obtains the first ratio, can further pass through：Maximum life × (1-
One ratio), it may be determined that the remaining life of strainer.
In one embodiment, the method further includes：Output is used to indicate the first prompt of the remaining life of the strainer
Information.
In one embodiment, the method can also include：It is defeated when the remaining life of the strainer is less than first threshold
Go out the second prompt message for being used to indicate and replacing strainer.
Using the technical solution of the embodiment of the present invention, by combine the pollutant concentration for influencing the strainer service life, wind speed and
Determination of the strainer filtering efficiency to the remaining life of strainer, thus reality of the remaining life of the strainer obtained closer to strainer
Service life greatly improves the accuracy rate in strainer service life.On the other hand, it also avoids carrying due to the inaccuracy that the strainer service life calculates
Preceding replacement strainer delays replacement strainer, the former can bring certain economic loss, the latter that can reduce air purification to user
Message, to which air purification effect can be greatly promoted in this respect.
