Description
Technical Field
The utility model relates to the technical field of protective masks, in particular to an improved KN95 mask.
Background
At present, medical staff and some persons related to epidemic prevention and control need to wear the KN95 mask for a long time when working, and some infectious disease patients and the close contact persons thereof also need to wear the KN95 mask in daily life.
However, the existing KN95 mask is only provided with a metal strip at the position of the nose bridge above the mask, so that the upper part of the mask can be tightly attached to the face, and the lower part of the mask cannot be tightly attached to the chin; moreover, for some wearers suffering from infectious diseases, if the mask is not tightly sealed, germs may be transmitted to the external environment through the gas exhaled by the patient, and people around the mask are affected, so that the existing KN95 mask cannot fully meet the requirement of epidemic prevention and control.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an improved KN95 mask, which can enable the lower part of the mask to be tightly attached to the chin of a person, prevent gas from entering the mask from the lower part of the mask, and improve the sealing property of the mask.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides an improvement type KN95 gauze mask, includes gauze mask main part, bridge of the nose metal strip, band, bridge of the nose metal strip sets up the outside top of gauze mask body is along central line symmetric position, the band symmetric connection be in the one side that the gauze mask body exposes, its characterized in that: the position department that the below of gauze mask body corresponds with the chin is provided with the chin metal strip.
In one embodiment of the present invention, the chin bar is disposed outside the mask body.
In another embodiment of the present invention, the chin metal bar is disposed between the outer layer nonwoven fabric and the inner layer nonwoven fabric of the mask body.
Preferably, the metal strip of the chin is an aluminum metal strip.
Compared with the prior art, the utility model has the following beneficial effects:
according to the improved KN95 mask, the chin metal strip is arranged at the position, corresponding to the chin, below the mask, so that the lower part of the mask can be tightly attached to the chin, compared with the existing KN95 mask, external droplets, aerosol and the like can be prevented from entering the mask from a gap between the lower part of the mask and the chin, the sealing performance of the mask is further improved, particularly for some people working in a working environment with infectious germs for a long time, viruses can be better prevented from entering the mask through the external droplets, the aerosol and the like, and for some wearers with infectious diseases, the gas exhaled by an infected person can be better isolated from the external environment, the germs are prevented from entering the external environment, and the safety is improved.
