Abstract

The invention discloses a prediction method and a prediction device for remaining life of a filter screen, and air purification equipment. The prediction method comprises the steps of: acquiring current dust concentration of the filter screen in target equipment, wherein the current dust concentration is obtained through acquiring environmental dust concentration of the filter screen within a preset time period; calculating an initial mass of pollutants absorbed by the target equipment based on the current dust concentration; determining a theoretical absorption amount of the pollutants by thetarget equipment; calculating an actual mass of pollutants absorbed by the target equipment based on the initial mass of the pollutants absorbed by the target equipment and the theoretical absorptionamount of the pollutants; and estimating the remaining service life of the filter screen according to the actual mass of pollutants absorbed by the target equipment and an accumulated purification amount of particulate pollutants by the filter screen. The prediction method and the prediction device solve the technical problems that the remaining service life of the filter screen of an air purifier is estimated by using the turn-on duration and the estimation result is imprecise in the related art.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a method and device for estimating the remaining life of a filter screen, and air purification equipment. Background technique [0002] In related technologies, currently used air purifiers all use filters to filter impurities in the air. Therefore, the service life of the filter directly affects the normal use of the air purifier; and the current calculation method for the life of the filter is often used The service life of the filter is estimated by the length of the boot time. This calculation method only estimates the remaining service life of the filter based on the boot time of the air purifier, without considering the type and quality of the pollutants filtered by the filter. The estimated results Inaccurate, resulting in serious attenuation of filter life, seriously inconsistent with the actual situation, resulting in waste of filter. [0003] For the above pr...
