Background With the acceleration of industrialization progress and the continuous improvement of urban level, the air pollution problem is increasingly prominent, and the air pollution problem becomes a global public health challenge. In this context, air purifiers have been widely used and continuously developed as a key device for improving indoor air quality. The traditional air purifier mainly removes particulate matters, gaseous pollutants and microorganisms in the air through physical filtration (such as a HEPA filter screen), electrostatic adsorption, photocatalysis, anion generation and other technical means. The core aim is to effectively reduce the concentration of PM2.5, pollen, peculiar smell, volatile Organic Compounds (VOCs), bacteria and viruses and other pollutants in a closed or semi-closed space, and ensure the health and comfort of residents. From the drive and control aspects, the operation mode of the existing air purifier has undergone an evolution from manual control to automatic intelligent control. Early products rely on the manual switching on and shutting down of user and adjust wind speed gear more, lack the real-time response ability to air quality. With the progress of sensor technology, modern air purifier generally integrates particulate matter sensor, gas sensor, temperature and humidity sensor etc. and can automatically detect ambient air quality and adjust running state accordingly, for example, automatically increase fan rotational speed when pollutant concentration rises, realizing "detection-feedback-regulation" closed-loop control. In addition, many products have supported remote control, enabling users to remotely monitor air quality data and manipulate the device by connecting to a smart phone application through Wi-Fi or bluetooth. The intelligent upgrading obviously improves the user experience and the purification efficiency, but is still limited to single machine automation of the equipment, and lacks higher-level coordination and optimization capability. In the related art, the rise of big data, the internet of things and artificial intelligence technology brings new opportunities for the development of air purifiers.
