Image detection system for filter screen of air purification device

Abstract

The invention provides an image detection system for a filter screen of an air purification device, and relates to the field of air purification, in particular to a filter screen detection system. The filter screen of the air purification device (an air purifier and a fresh air machine) is mainly provided with a coarse filter screen, a primary efficiency filter screen, an electrostatic dust removal device, a high efficiency filter screen and the like, wherein a camera with an LED (Light Emitting Diode) compensation lamp is arranged at a corresponding position on each filter screen; each camera is used for photographing the corresponding filter screen; a first group of pictures are photographed from first operation of the air purification device, then pictures are photographed once every week, are uploaded to a server and are compared with the pictures photographed at the first time on the server to examine an ash attachment condition on the filter screen, an aging condition of the filter screen and the like; if the filter screen is required to be cleaned or replaced, a prompt is provided at a host and a client to remind the user to maintain.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a detection system for a dust removal filter including an air purification device. technical background [0002] As people pay more and more attention to air pollution, air purification devices such as air purifiers and fresh air fans are changing from novelty products to essential household appliances.
