Air purification method and device, electronic equipment and storage medium

The invention provides an air purification method and device, electronic equipment and a storage medium, and relates to the technical field of control. The method comprises the steps that environment index values collected by sensors corresponding to all environment indexes are obtained; determining an indoor environment quality value based on the plurality of environment index values; under the condition that the indoor environment quality value is smaller than a preset quality value, the number of indoor target persons is obtained; determining a target purification mode corresponding to the target number of personnel based on a corresponding relationship between the number of personnel and the purification mode; and the indoor air is purified based on the target purification mode, automatic selection of the purification mode is achieved, the indoor air can be effectively purified, and the air purification effect is improved. 本发明提供一种空气净化方法、装置、电子设备和存储介质，涉及控制技术领域，其中方法包括：获取各环境指标对应的传感器采集的环境指标值；基于多个所述环境指标值，确定室内环境
