Abstract

The invention discloses a formaldehyde filter screen replacement reminding method and device of an air purifier, the air purifier and a storage medium. The method comprises the following steps: acquiring formaldehyde pollution concentration when the air purifier is in work, and determining the service time of the air purifier based on the formaldehyde pollution concentration and preset formaldehyde pollution reference concentration; modifying the service life of a formaldehyde filter screen of the air purifier based on the service time of the air purifier and the initial reference life of theair purifier; determining whether reminding information is generated or not according to the modified service life of the formaldehyde filter screen, wherein the reminding information is used for reminding a user of replacing or cleaning the formaldehyde filter screen.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a formaldehyde filter replacement reminder method and device for an air purifier, an air purifier and a storage medium. Background technique [0002] An air purifier is a product that filters the air. Existing air purifiers mainly use activated carbon adsorption and decomposition to remove formaldehyde. As the use time increases, the filtration efficiency of the formaldehyde filter in the air purifier will gradually decrease. Therefore, the formaldehyde filter of the purifier needs to be replaced or cleaned regularly. [0003] At present, most purifiers generally have a replacement reminder for the particulate filter, but there is no filter replacement reminder for the formaldehyde filter. And the existing formaldehyde filter replacement reminder is simply setting a fixed time countdown to calculate the life of the formaldehyde filter. It can be seen that in the pr...
