The automated cleaning of row filtering net cleaning or control screen pack；When filtering net cleaning number of times reaches default cleaning time, in execution
Step S30 is stated, i.e., when filtering net cleaning number of times reaches default cleaning time, the execution judgement airstrainer is current to be tired out
The step of whether meter purification value is more than or equal to the first accumulative purification value.
In the present embodiment, above-mentioned default cleaning time can be set according to actual conditions, it is preferable that in the present embodiment,
During the default cleaning time is for 2 times or 3 times, i.e. the present embodiment, after the airstrainer cleaned 2 times or 3 times, in institute
Airstrainer operation next time is stated when using, judges whether the current accumulative purification value CCM of airstrainer is more than
In the first accumulative purification value SM, that is, judge whether airstrainer needs to change.
The replacing control method of the present embodiment airstrainer, when filtering net cleaning number of times is not up to default cleaning time
When, can timely and accurately remind user's clean air screen pack or control air purifier enters to airstrainer in time
Row automated cleaning；When filtering net cleaning number of times reaches default cleaning time, user can be timely and accurately reminded to change empty
Gas screen pack.
The present invention also provides a kind of air purifier, and the air purifier can be independently arranged, it is also possible to be arranged on air-conditioning
In the other equipments such as device, for the purification function of air.The air purifier includes the monitoring of airstrainer service life
Device, the monitoring device of the airstrainer service life is used to control exactly the replacing construction of airstrainer, in time simultaneously
User is reminded to change airstrainer exactly.
Reference picture 5, in one embodiment, the monitoring device 100 of the airstrainer service life includes dust sensor
101st, main control module 102 and screen replacing prompting module 103.
Wherein, the dust sensor 101：Dust concentration value for detecting airstrainer current operating environment；This
In embodiment, the dust sensor 101 is between the air intake plate and the airstrainer of the air purifier.
In the present embodiment, the dust sensor 101 detects air within the default time period according to default detection cycle
The dust concentration value of screen pack current operating environment.It should be noted that in other embodiments, the dust sensor 101
Can also be within the default time period, timing detects the dust concentration value of airstrainer current operating environment.It is above-mentioned default
The size of the duration of time period and default detection cycle can be set according to actual conditions.
The main control module 102：For according to the accumulative of the dust concentration value and air filtration net filtration air for arriving
Run time, determines the current accumulative purification value of airstrainer；And judge the current accumulative purification value of airstrainer
Whether more than or equal to the first accumulative purification value；When the current accumulative purification value of airstrainer tires out more than or equal to described first
During meter purification value, screen replacing reminder message is sent；
Specifically, in the present embodiment, the main control module 102 is used for the dust concentration sensor 101 default
In time period, the dust concentration value detected according to default detection cycle makees mean value calculation, obtains airstrainer and currently transports
The dust concentration value of row environment；Then the dust concentration value and air filtration net filtration sky are obtained as mean value calculation according to above-mentioned
The accumulated running time of gas, according to default computation rule, determine the current accumulative purification value of airstrainer, it is described default
Computation rule be：
CCM=X (HC*T)；
Wherein, CCM is the current accumulative purification value of airstrainer, and HC is detected by the dust sensor 101
Airstrainer running environment dust concentration value, T for air filtration net filtration air accumulated running time, X is default
