Description

Dual cycle mask for separating mouth and nose

Technical Field

The utility model relates to the technical field of masks, in particular to an oral-nasal separation double-circulation mask.

Background

The mask is used as a daily protective article and is generally used for filtering air entering the nose and the mouth, and aims to block harmful substances such as dust, peculiar smell, spray and the like and prevent the harmful substances from entering the nose and the mouth of a wearer. In the postepidemic situation, the mask becomes an indispensable protective article for people's daily life.

Under the large background of wearing the mask for a long time at present, waste gas and saliva spray generated from the mouth part, carbon dioxide waste gas generated from the nose part and the like can remain and accumulate in the mask, so that the mask has serious odor and bacteria are easy to breed. Because the mouth and nose breathing of the traditional disposable mask are in the same cavity, the generated peculiar smell can be repeatedly inhaled into the nasal cavity, so that discomfort in the use process of people is caused, cross infection of the oral cavity and the nasal cavity can be caused, and certain health hidden trouble exists.

Meanwhile, the outer edge of the existing disposable mask cannot be well attached to the face, and the mask is also easy to jack up by exhaled waste gas during exhalation, so that the protection effect of the mask is greatly reduced.

In addition, the inner layer of the existing disposable mask is easy to attach to the mouth and nose, so that the filtering area which can be fully utilized is reduced, the respiratory resistance is increased, the filtering efficiency is reduced, and the comfort is reduced; the nasal mask is more easy to accumulate a large amount of vapor and heat generated during nasal breathing between the mask and the face, thereby bringing uncomfortable feeling and possibly causing adverse reactions such as skin redness, swelling, allergy and the like. Moreover, heat can also overflow from the upper edge of the mask along with water vapor, and if a user wears glasses, eyes of the user can frost, so that the work of the user is seriously influenced.

In addition, the existing disposable mask has short effective protection time because bacteria are easy to breed.

However, in order to ensure smooth breathing, the silica gel gasket used in the air valve of the existing double-circulation mask cannot be tightly connected with the air valve, and is easy to prop open in the breathing process, so that the mouth or nasal cavity chamber is directly communicated with the external environment, the protection effect is reduced, and even potential safety hazards are brought; if additional gaskets are added to the air valve, the design of the air valve is omitted, and an integrated replaceable filter disc is used.

Therefore, the mouth-nose separation double-circulation mask is provided, and the mouth-nose separation double-circulation mask can effectively resist bacteria and can be repeatedly used.
