Mask

Abstract

The invention provides a mask. The mask comprises a mask body and tying belts used for fixing the mask body to the mouth and the nose. A separator is arranged on the inner side of the cover body; thefront side edge of the separator is fixedly connected with the inner side of the cover body; the rear side of the separator is used for tightly fitting with areas above lips and below noses of a humanbody; an inspiration chamber is formed on the inner side of the mask body, above the partition body and at the nose; an expiration chamber is formed by the inner side of the mask body, the lower partof the separator and the opening; during inspiration, inspiration is performed in the inspiration chamber through the nasal cavity; during expiration, the patient exhales through the oral cavity; gasis exhausted out of the mask body through the expiration chamber; therefore, the air in the inspiration chamber can be always clean and dry air; the problem that oxygen deficit is caused by frequently inhaling waste gas can be solved, exhaled waste gas is exhausted through the expiration chamber below, the air permeability of the mask body in the inspiration chamber area is not affected, the problems that the air permeability of the mask body in the inspiration chamber area is reduced and the adsorbability becomes poor are solved, the expiration chamber is located below, and exhaled water vapor cannot fog lenses of goggles or glasses.

Description

technical field [0001] The invention relates to the technical field of medical protective equipment, in particular to a mask. Background technique [0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose.
