Abstract

The invention discloses a friction electric-adsorption mask which comprises a mask carrier, a first friction layer and a second friction layer. An air inlet is formed above the mask carrier; the firstfriction layer is located at the position of the air inlet of the mask carrier; the second friction layer and the first friction layer can contact with each other, can be separated, and can be in mutual friction; and the first friction layer and the second friction layer are made of materials with different friction electrode sequences. A friction nanometer power generator is placed in the air inlet of the friction electric-adsorption mask, the mechanical energy during the human body breathing process is converted into electric energy through the repetitive expiration and inspiration process,and the friction layers have the functions of filter layers, so that outside small-particle-size particles are electrostatically adsorbed and effectively filtered, the particle size filtering efficiency is improved, and the service life of a filtration membrane is prolonged.

Description

technical field [0001] The disclosure belongs to the technical field of triboelectric power generation and electrostatic adsorption, and relates to a triboelectric adsorption mask. Background technique [0002] As the process of industrialization continues to accelerate, along with the continuous consumption of fossil fuels and the intensification of environmental pollution, a large number of wearable protective equipment has emerged to monitor and protect various functional areas of the human body. Breathing is a periodic exercise for the human body to maintain the necessary vital characteristics, and the gas composition it inhales is crucial to the health of the human body. Therefore, respiratory protective equipment is required to purify the inhaled gas in polluted weather or special working environments. However, most protective equipment rely solely on traditional physical filtration, physical adsorption and other methods, and the filtration efficiency of the harmful ti...
