Description

Mask

Technical Field

The invention relates to the field of masks, in particular to a mask.

Background

The mask is a sanitary article, is generally worn at the mouth and nose part and is used for filtering air entering the mouth and nose so as to achieve the purpose of preventing harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer, and becomes a necessity for life, trip and work of people in a special period of coronavirus. At present, the mask that can block coronavirus usually adopts three layer construction, includes upper non-woven fabrics, melt-blown fabric, the non-woven fabrics of lower floor that superpose from top to bottom in proper order respectively, and this kind of mask simple structure nevertheless has the effect of filtering coronavirus poor, the air permeability is relatively poor, the gas tightness is relatively poor scheduling problem. When people respiratory gas volume increases, gas through the gauze mask increases, gas volume between human face and the gauze mask increases and atmospheric pressure increases, because the surface area of gauze mask is fixed, a large amount of gas is difficult to all filter from the gauze mask in the short time, gaseous promotion gauze mask between human face and the gauze mask is towards the direction removal of keeping away from human face, make to have the clearance between gauze mask and the human face, some gas is discharged from the gauze mask gap, it has the gap state to probably keep having for a long time after the gauze mask gap forms, it is internal to lead to outside gas to pass through the gap suction human body, the combustion gas is not filtered through the gauze mask body completely, the filter effect is poor, the gauze mask is to the bacterium to having been reduced, the filter effect of virus.

Patent application No.: CN 201920140937.7 discloses a mask, which comprises a mask body and two sheet-shaped ear bands. The mask body is suitable for covering the mouth and the nose.
