The invention belongs to the technical field of respiratory protection equipment, and discloses an intelligent sensing monitoring and automatic replacement type respiratory protection device and method.The intelligent sensing monitoring and automatic replacement type respiratory protection device is characterized in that massive face data are analyzed and modeled by means of a 3D printing technology and an AI
algorithm, and a shell
assembly fitting a
face contour skeleton is printed according to human face structural features;
mechanical energy-
electric energy is converted into
static charges on the surface of a
filter material of the shell
assembly for self-supply, and the friction nano-generator adsorbs and captures tiny particles; and the integrated sensing
chip bin is used for automatically sensing and responding to the change of
breathing resistance of a wearer and the accumulation condition of the
filter material in combination with multi-mode sensing, performing early warning in time, automatically replacing the
filter material, automatically adjusting the filtering working state of the filter material of the shell
assembly and completing the replacement of the filter material. According to the invention, a friction nanometer power generation technology is innovatively introduced, so that the
adsorption effect on tiny particulate matters is improved, and the dust and poison capturing efficiency is remarkably improved.
