Description

Mask {MASK}

The present invention relates to a mask, and more particularly, to a mask for preventing inhalation of pollen or dust, ultrafine dust such as PM2.5, and viruses.

The mask should basically have good breathing and have a filtering effect to prevent the invasion of dust and bacteria. Usually, an earring strap is attached to a filter such as cotton or nonwoven fabric of pure cotton yarn so that it can be hung on the ear to prevent bacteria growth. Patients who are concerned about infection or who are concerned about infecting others, workers in workplaces where a lot of dust is generated, as well as general people who are concerned about fine dust when they go out are also using it.

In the case of a currently generally used mask, complete breathing is not performed through the filter of the mask. The main causes are as follows. The filter of the mask is flat, but the user's face protrudes from the nose and lips, so air enters and exits between the cheekbones and the nose and lips. This is because complete filtering is not possible.

In addition, when the user wears glasses, when exhaling, warmth is discharged to both sides of the nose, and there is a problem that the glasses are fogged.

On the other hand, a mask including a nose adapter for a mask that can be inserted into the nostril has been developed, but there is a problem that a foreign body feeling and a feeling of wearing are deteriorated due to the volume and weight of the nose adapter, and the degree of insertion of the nose adapter into the nostril is not uniform. Or, it was not able to solve the problem of not showing the function of the nose adapter because it easily deviated from the nostril.
