Air cleaning breathing mask

Abstract

The invention relates to an air cleaning mask, in particular to an air cleaning and anti-poison health mask, pertaining to the technical field of daily necessities. The mask is made in a primary way that the lining of active carbon fiber fabric is filled into a double-face interlayer mask body and the nostril area of the interlayer mask is cut with an opening. A curtain-type flap with a breathing gap which can be opened and closed on the right, left and lower edges is sewed at the upside of the outside of the opening. The breathing gap which can be opened and closed on the right, left and lower edges is sewed and connected by a limit net. Both sides above the nostril area on the inner face of the mask body are heaved by thickening so that two elastic gas blocking cushions are formed. The mask of the invention not only can absorb particulate matters but also filter various harmful gases. When in exhalation, the flap is vibrated by air current to slit so as to form a water vapor channel. On the one hand, the particulate matters absorbed on the surface of the mask are shaken off; on the other hand, the mask soaked with the water vapor, air permeability losing of the mask caused by the adhesion and blocking of the particulate matters can also be avoided, thus being capable of avoiding the hidden trouble that the water vapor is forced to eject from the gap from areas at both sides of the bridge of the nose.

Description

technical field [0001] The invention relates to an air filter mask, in particular to an air filter and anti-virus sanitary mask, which belongs to the technical field of daily necessities. Background technique [0002] With the increasing number of fuel vehicles in cities, the city's harmful gases with engine exhaust as the main component are becoming denser and denser, and the streets and alleys are shrouded in diffuse exhaust. Facing the increasingly serious and irreversible air pollution growth rate, the only thing that vulnerable groups can do is to wear a pair of masks in order to filter harmful gases. However, ordinary masks can only filter out part of the inhalable particulate matter, which is of no help to the harmful gas whose main component is exhaust gas. Moreover, due to the congestion of particulate matter and the bonding with exhaled water vapor, the soaked mask quickly loses its breathability. It made it more difficult for people to breathe, and black stains a...

Problems solved by technology

However, ordinary masks can only filter out a part of the inhalable particles, which are of no help to the harmful gases whose main components are exhaust gas. Moreover, due to the congestion of particles and the bonding with exhaled water vapor, the wet masks quickly lose their breathability. It makes breathing more difficult, and black stains appear on the nostril area of ​​the mask

Due to the poor air permeability of the soaked and stuffed mask, the exhaled water vapor can only be sprayed out from the gap between the mask on both sides of the bridge of the nose and the cheek joint area. If it is in the cold season, the water vapor will accumulate fog and frost on the eyelashes and glasses. , thereby reducing visibility or even blocking the entire line of sight, which is extremely dangerous for cyclists
