Abstract

An embodiment of the invention discloses a method and a device for judging the service lives of filter screens. By the aid of the method and the device, the technical problem of wastage of existing filter screens due to the fact that users are unscientifically and inaccurately reminded of replacing existing purifiers by the aid of various timers can be solved. The method for judging the service lives of the filter screens in the embodiment of the invention includes acquiring air quality detection parameters and real-time outlet air quantities; determining current dust holding capacity of the filter screens according to the detection parameters and the real-time outlet air quantities and acquiring consumption proportions of the filter screens by means of computing; prompting users to treat the filter screens if requirements of filter screen cleaning threshold values are met by the consumption proportions.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a method and device for judging the service life of a filter screen. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.) , bacteria, allergens, etc.), products that effectively improve air cleanliness are mainly divided into household, commercial, industrial, and building. [0003] There are many different technologies and media in an air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure photomineralization technology, HEPA high-efficiency filtration technology, electros...
