Abstract

The embodiment of the invention discloses a filter screen lifetime determination method, an air purifier and a computer storage medium. The method includes: detecting the pollutant concentration of the environment every preset time period, acquiring the air speed in the air purifier, and acquiring the filter screen filtration efficiency of the air purifier; determining the dust holding capacity based on the pollutant concentration, the air speed and the filter screen filtration efficiency acquired at the preset time periods; subjecting the dust holding capacity obtained at all the preset timeperiods to addition so as to obtain cumulative dust holding capacity; and determining the residual life the filter screen in the air purifier based on the cumulative dust holding capacity.

Description

technical field [0001] The invention relates to an air purifier, in particular to a method for determining the service life of a filter screen, an air purifier and a computer storage medium. Background technique [0002] The filter screen of the air purifier needs to be replaced after the service life of the filter screen reaches a certain time limit. However, the service life of the current filter screen is usually fixed and cannot be changed. When the air purifier is turned on for the first time, the life time of the filter screen starts counting, and when the accumulated time reaches the set fixed time, the life of the filter screen is considered to be over. However, this calculation method of the life of the filter only considers the working time and does not take into account other factors affecting the life of the filter, which is inaccurate and affects the purification effect of the air. Contents of the invention [0003] In order to solve the existing technical p...
