Nano-composite fiber PM2.5 static breathing mask

Abstract

The invention relates to a nano-composite fiber PM2.5 static breathing mask, and belongs to the technical field of haze protection. The PM2.5 static breathing mask includes a mask body and a filteringdevice. The mask body adopts a face-type design and can attach to a human face tightly; and the mask body includes a nose fixing line, a face sealing ring, and a band, has a cotton lining, and can provide a comfortable environment for the face. The filtering device is a detachable PM2.5 filtering layer, and includes a nano-composite fiber PM2.5 static material, a breathable waterproof filtering film, and a fiber layer. The breathing mask is fluffy and breathable, has excellent air permeability and filterability, can be shaped easily, has excellent attachment performance, broad-spectrum antibacterial property, less filtering resistance, and a good filtering effect, can be used in haze weather, garbage disposal working stations, construction sites, production workshops, and other dust working places, can protect people from PM2.5 pollution, can effectively improve the working and life quality of people.

Description

technical field [0001] The invention relates to an electrostatic mask capable of purifying air, especially suitable for filtering PM2.5, and belongs to the technical field of haze protection. Background technique [0002] PM2.5 is fine particulate matter, which refers to particulate matter in the ambient air with an aerodynamic equivalent diameter less than or equal to 2.5 μm. It can be suspended in the air, and the higher the concentration in the air, the more serious the air pollution. PM2.5 has small particle size, large area, strong activity, easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation distance, so it has an impact on human health and atmospheric environment quality. very big. PM2.5 can penetrate deep into the bronchioles and alveoli of the human body, directly affect the ventilation function of the lungs, make the body prone to hypoxia, and cause car...

AI Technical Summary

Problems solved by technology

Cotton masks cannot resist particles with a particle size of only 2.5 μm, and the airflow resistance is large, which may easily cause breathing difficulties for the wearer; the dust blocking principle of gauze masks is mechanical filtration. Some large particles of dust are blocked in the gauze. For some fine dust, especially the dust less than 2.5μm, it will pass through the mesh of the gauze and enter the respiratory system. If you do not pay attention to hygiene, it will also lead to the reproduction of bacteria; The mask has the effect of reducing some peculiar smells, but the protective efficiency against particulate matter has not been significantly enhanced. At the same time, it is also a kind of particle itself, which may be inhaled by the wearer; the non-woven mask has poor sealing performance and poor ventilation effect

The above masks need to be thrown away and replaced after being worn several times or even once, and are not suitable for glasses wearers, as they tend to blur the lenses and cause inconvenience to glasses wearers
