Abstract
The invention discloses a low-resistance particle-filtering protective gauze mask with helical structures. The helical structures are inlaid into the surface of the gauze mask and used for filtering particles in inhaled gas and quickly releasing hot water vapor and exhaust gases such as carbon dioxide which are generated through breathing. Each helical structure comprises a lobed helical tube wall and multiple helical fins arranged in the tube wall; the helical tube inner walls and the helical fins are coated with degradable biogel; the helical structures can induce gas flowing through the helical structures to generate vortexes and enable the inhalable particles carried in the gas to move towards the direction of the helical tube inner walls and the helical fins and be adhered to the degradable biogel applied to the helical tube inner walls and the helical fins, therefore, the effect of filtering out the inhalable particles in air is achieved, and the air inhaled into a human body is purified. Due to the openness of the helical structures, the breathing resistance of inhalation is smaller, the water vapor and the exhaust gases such as carbon dioxide can be quickly released when exhalation is performed, and therefore the breathing experience is more comfortable and refreshing.
Description
Technical field
