Functional anti-haze mask for civil use

Abstract

The invention discloses a functional anti-haze mask for civil use. The anti-haze mask comprises a mask main body which can cover a mouth, a nose and a lower jaw, and a pair of ear-hung parts which are connected to two ends of the mask main body and are hung and hooked on ears, wherein in a direction from the bridge of the nose to the lower jaw, the mask main body is divided into a nasal cavity coverage region which is provided with a nose bridge soft bar, a respiratory cavity region and a lower jaw coverage region; a storage part, which is used for storing a filter sheet, is arranged in a respiratory cavity, and composite adsorbent material layers, which have an adsorbent effect on formaldehyde, benzene, TVOC (total volatile organic compound) and particulate matters in haze and have an inhibitory effect on bacteria and viruses in the haze, are included in the filter sheet; when the mask is symmetrically folded, the nose bridge soft bar in the nasal cavity coverage region forms an angle of 80-95 degrees with the center line of the mask main body; the center line of the respiratory cavity region is an arc that a radian is 0.25-0.4 [pi]; and the center line of the lower jaw coverage region forms an angle of 90 degrees with the edge of the mask main body in the region. The mask main body, with the unique design, has an anti-haze function, and meanwhile, the mask main body can get into full contact with the face of a wearer, so that the mask is good in sealing effect and high in comfort, and moreover, the mask is good in filtering effect and air permeability.

Description

technical field [0001] The invention relates to a mask, in particular to a functional anti-haze civilian mask. Background technique [0002] With the development of industrialization in our country, the popularization of automobiles, the increase of germs, and the pollution of heavy metals, the air pollution has become more and more serious. The local air formaldehyde exceeds the standard, and the haze weather has increased, which is very harmful to human health, especially PM2. 5 Exceeding the standard is serious. With the increasingly severe smog weather, which seriously endangers people's health and safety, and the living population in polluted areas reaches 800 million people, ordinary masks have basically no blocking effect on formaldehyde and polluting particles in the air. Although some smog masks have no effect on pollutants There is some blocking, but less effective. [0003] Mainly now it is difficult to take into account the two effects of filtration and ventilat...

Problems solved by technology

[0002] With the development of industrialization in our country, the popularization of automobiles, the increase of germs, and the pollution of heavy metals, the air pollution has become more and more serious. The local air formaldehyde exceeds the standard, and the haze weather has increased, which is very harmful to human health, especially PM2. 5 Exceeding the standard is serious. With the increasingly severe smog weather, which seriously endangers people's health and safety, and the living population in polluted areas reaches 800 million people, ordinary masks have basically no blocking effect on formaldehyde and polluting particles in the air. Although some smog masks have no effect on pollutants There is some blocking, but the effect is poor

[0003] Now it is mainly difficult to take into account the two effects of filtration and ventilation, and it has not been solved so far. It is necessary to develop a mask that can take into account both filtration and ventilation.

[0004] Now commonly used masks use non-woven fabrics, cotton fibers, activated carbon fibers and other materials to filter pollutants in the air to reduce the inhalation of formaldehyde and other polluting particles and germs, but the filter effect is not good if the mask is thin, and the mask is thick and breathable Poor performance, affecting breathing
