Abstract

The invention provides a purifier filter screen expiration reminding method and device and a purifier. The purifier filter screen expiration reminding method comprises the steps of acquiring the concentration value of first particulate matter, wherein the concentration value of the first particulate matter is the concentration value of particulate matter existing before purification conducted by a filter screen of the purifier; acquiring the concentration value of second particulate matter, wherein the concentration value of the second particulate matter is the concentration value of particulate matter existing after purification conducted by the filter screen of the purifier; calculating the filtering capacity value of the filter screen of the purifier according to the concentration value of the first particulate matter and the concentration value of the second particulate matter; acquiring a purifying capacity-free threshold value, comparing the filtering capacity value with the purifying capacity-free threshold value, and reminding people of expiration of the filter screen of the purifier when the filtering capacity value is smaller than the purifying capacity-free threshold value. By the adoption of the method, filter screen expiration reminding accuracy can be improved, and resource waste or using of a filter screen without purifying capacity is avoided.

Description

technical field

[0001] The invention relates to the technical field of purifiers, in particular to a method and device for prompting the expiration of a filter screen of a purifier and a purifier. Background technique

[0002] At present, the general algorithm for judging the expiration of the filter screen of the purifier is: compare the cumulative running time of the motor with the total usable time of the filter screen, and when the cumulative running time is greater than the usable time, prompt the user to replace the filter screen. However, when the purifier is operating in a cleaner environment, the filter screen that does not need to be replaced may be prompted to be replaced, resulting in waste; or, when the purifier is operating in a more polluted environment, the filter screen that needs to be replaced If the network does not prompt, the purpose of purification cannot be achieved. Contents of the invention

[0003] The present invention aims to solve one of the ...
