Abstract

The invention discloses a filter mask for harmful particulate pollutants. The filter mask comprises a gas filter unit, a surface cup and a mask shield, and one end of the surface cup is hermetically docked with one end of the mask shield; the gas filter unit comprises a filter barrel, a filter membrane and a sterilization unit arranged in the filter barrel; the filter membrane is arranged at one end of the filter barrel; the filter membrane comprises a hydrophilic spinning bonded nonwoven fabric layer, a first melt-blowing nonwoven fabric layer, a wood pulp layer, a nuclear pore membrane filtration layer and a water-repellent spinning bonded nonwoven fabric layer which are laminated and composited in sequence from the position close to the inner side of the mask shield to the outer side of the mask shield; the sterilization unit comprises a gas inlet distribution disc, a capillary gas-guide tube, a gas outlet collection disc and an ultraviolet lamp; two ends of the capillary gas-guide tube are communicated with the gas inlet distribution disc and the gas outlet collection disc, and the capillary gas-guide tube is arranged in a spiral winding manner between the gas inlet distribution disc and the gas outlet collection disc; the ultraviolet lamp is used for performing ultraviolet irradiation on the capillary gas-guide tube. The filter mask has the advantages of use comfort, good user experience, thorough sterilization and safety in use.

Description

Technical field [0001] The invention belongs to the technical field of human health breathing equipment, and particularly relates to a harmful particulate pollutant filter mask. Background technique [0002] PM2.5 is fine particulate matter. Fine particulate matter refers to particulate matter in ambient air with an aerodynamic equivalent diameter of 2.5 microns or less. The chemical composition of fine particles mainly includes organic carbon, elemental carbon, nitrate, sulfate, ammonium salt, sodium salt, etc. It can be suspended in the air for a longer time, and the higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small component in the earth's atmosphere, it has an important impact on air quality and visibility. Compared with the coarser atmospheric particulate matter, PM2.5 has a small particle size, a large area, strong activity, easy to carry toxic and harmful substances, and has a long residence time in the atmosphere an...
