Self-adaptive mask and respiratory protection system thereof

The invention relates to a self-adaptive mask. The self-adaptive mask comprises a mask base layer, an internal module and an inner side module, and the mask base layer is provided with at least one through hole. The internal module comprises a gas filtering module, a sensor module and a processor module. And the gas filtering module is used for filtering the gas flow passing through the through hole. The sensor module is used for detecting the first content and the second content in real time. The processor module is used for calculating the filtering efficiency in real time according to the first content and the second content. And the processor module is also used for transmitting the data to terminal equipment. The inner side module comprises a nanometer power generation module and an energy storage module. The nanometer power generation module is used for converting mechanical energy in airflow generated when the user wears the mask to breathe into electric energy. The energy storage module is used for st
