The purpose of the embodiment of body, it is not intended that in the limitation present invention.
A kind of air purifier purification device life-span prediction method, air purifier purification device include by HEPA (High-
Efficiency Particulate Air, efficiency particulate air) or other absorption dust particles filtering material made of filter
Net and specific adsorption include the activated-carbon device or material of the VOC pernicious gas such as formaldehyde.As shown in Figure 1, air purifier purifies
Device lifetime prediction technique the following steps are included:
Step S110: real-time detection air purifier local environment is currently cleaned object content concn.
It is cleaned the content concn that object content concn refers to the purification object of air purifier in air, such as PM2.5 value/first
Aldehyde value/VOC concentration value etc..It specifically can be by PM2.5 sensor or formaldehyde/VOC sensor to PM2.5 dust/first in air
Aldehyde/VOC concentration is detected, and object content concn is currently cleaned.Being cleaned in each unit interval is obtained in real time
Object content concn can be used for being monitored air quality, to analyze practical working situation to air purifier purification device
Influence.
Step S120: the current purge speed, unit purification duration and original absorption gross mass of air purifier are obtained.
Specifically, purification speed refers to the speed that air is purified when air purifier work, and unit, which purifies, calculates one in duration
Secondary newly-increased adsorbance, unit clarifier duration are a regular time length, and specific length can adjust according to the actual situation；Only
Changing speed and unit purification duration can directly obtain from air purifier, such as learn purification by the instrument parameter of air purifier
Speed purifies duration by the available unit of the internal clock unit of air purifier.Original absorption gross mass is to calculate newly
The sum of the quality of adsorption that all periods calculate before increasing adsorbance.
Step S130: it is obtained currently according to object content concn, current purge speed and unit purification duration is currently cleaned
Newly-increased quality of adsorption in unit time period.
Specifically can be, which directly will currently be cleaned object content concn, current purge speed and unit, purifies duration three phase
The multiplied newly-increased quality of adsorption in the unit interval.Air purifier includes multiple work in one of the embodiments,
Gear；Current purge speed is related to operation range, and each operation range correspondence prestores a gear linear function, the shelves
Bit line function characterizes the linear corresponding relation that the air purifier adsorbs gross mass and purification speed in different stalls, single
Position purification duration is a fixed duration, and being currently cleaned object content concn is the mean concentration in unit purification duration.Such as
Shown in Fig. 2, step S130 includes step S132 to step S136.
Step S132: it obtains in the current one period and is currently cleaned object content concn.It is cleaned object content concn
Value change over time and change, object content concn value is cleaned in unit time period may obtain multiple and different values, make even
Mean value is as calculated value.
Step S134: the current purge speed in the current one period is calculated according to gear linear function.
Since air purifier at a time can be only in a kind of operation range, air purifier shelves locating when working
Position is different, and corresponding purification speed would also vary from.The corresponding current purge speed of each operation range can be directly according to right
The gear linear function answered is calculated.
Specifically, step S134 includes step 1342 and step 1344 in one of the embodiments,.
Step 1342: obtaining the operation range of current one period.It can according to the parameter display interface of air purifier
Directly obtain the operation range of current one period.
