Air purifying device, reminding system for service life of filter element thereof and reminding method

Abstract

The invention discloses an air purifying device, a reminding system for service life of a filter element thereof and a reminding method. The reminding system for the service life of the filter element comprises a first detector, a second detector, a processing device and a reminding device, wherein the first detector is used for detecting the pollutant concentration on a windward side; the second detector is used for detecting the pollutant concentration on an air exhausting side; the processing device is used for calculating the real-time filtering efficiency of the filter element according to the pollutant concentration on the windward side and the pollutant concentration on the air exhausting side of the filter element, calculating the pollutant purifying volume at this time according to the real-time filtering efficiency, the present air-level air volume, the opening time at this time and the pollutant concentration on the windward side and summing the pollutant purifying volume at this time and the historical pollutant purifying volume, thereby acquiring the total pollutant purifying volume. The reminding device is used for reminding according to the total pollutant purifying volume. The service life of the filter element is judged on the basis of the real-time filtering efficiency, a user can be more accurately reminded of replacing or cleaning the filter element and the secondary pollution can be avoided.

Description

technical field [0001] The invention belongs to the technical field of electric appliance manufacturing, and in particular relates to a system for reminding the life of a filter element of air purification equipment, a method for reminding the life of a filter element of air purification equipment, and the air purification equipment. Background technique [0002] Air purification equipment is a product that filters the air. The filtered dust and other pollutants (including solid and gaseous pollutants) will accumulate on the filter elements of the equipment. As the use time increases, the filtration efficiency of the purification equipment will decrease. Therefore, The filter elements of the purification equipment need to be replaced or cleaned regularly. Conventional filters are generally replaced or washed with water or electric purification, and can be continued to be used after being cleaned with water or a vacuum cleaner. However, the existing filter replacement or cle...

[0003] However, reminding the filter to replace or clean according to the accumulated time of use cannot truly reflect whether the filter has really reached the state of replacement or cleaning. The time for replacing the filter element has arrived, but the actual filter element collects very little pollutants, and the filtration efficiency (life) of th
