Abstract

The invention discloses air purifying equipment, and a detection method and device of a filter element. The detection method of the filter element comprises the following steps of: acquiring pollutant concentration before air is purified through a first sensor, and acquiring the pollutant concentration after air is purified through a second sensor; determining the purifying efficiency of the air purifying equipment according to the pollutant concentration before and after air is purified; and determining the using state of the filter element according to the purifying efficiency of the air purifying equipment. According to the air purifying equipment, and the detection method and device of the filter element disclosed by the invention, the using state of the filter element can be detected, the residue service life of the filter element can be directly and accurately judged, and the implementing difficulty is relatively small.

Description

technical field [0001] The present disclosure relates to the technical field of terminal equipment, and in particular to an air purification equipment and a detection method and device for a filter element. Background technique [0002] With people's attention to air quality, air purification equipment is gradually popularized in homes, workplaces and other places. The filter element in the air purification equipment can adsorb and filter impurities in the air such as PM2.5 and PM3.0. With the use of air purification equipment, more and more impurities are adsorbed on the surface of the filter element, which hinders the air circulation inside and outside the filter element and affects the air volume. The filter element will directly affect the air purification effect, so it is very important to detect the life of the filter element for air purification equipment. [0003] In related technologies, the remaining life of the filter element is mainly estimated by calculating t...
