Abstract

The disclosure relates to a detection method and device for air purification equipment and a filter element. The detection method of the filter element may include: determining the temperature change rate of the temperature sensor in the air purification equipment, the temperature sensor being arranged on the air outlet side of the air purification equipment; determining the use state of the filter element according to the temperature change rate . The air purification equipment, filter element detection method and device of the present disclosure can detect the use state of the filter element, and can accurately determine the remaining life of the filter element, and the implementation is less difficult.

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...
