This creation department reveals a personal air cleaning machine, which mainly contains negative ion generation module, sensing module, processing module, and display module. The negative ion generation module generates negative ions and transmits them into the preset range around the personal air cleaning machine. The environment sense sense group senses the surrounding of the personal air clean-up machine and produces a sensing signal. The processing module connects the negative ion generation module and the sensing module, and receives the sensing signal, and opens the application to produce control signal sensing signal corresponding to the sensing signal that meets the preset conditions, and produces historical sensing information according to the sensing signal, and the processing module provides historical sensing information according to the query signal. The displays module displays historical sensing information.

This patent is a personal air purifier, including air quality warning function (carbon dioxide, temperature, humidity, PM2.5), with mobile phone App, to provide a complete air purifier function.
