Description

Check valve structure applied to mouth cover

Technical Field

The utility model relates to the field of mask structures, in particular to a one-way valve structure applied to a mask.

Background

The mask is a sanitary article, and is generally used for filtering air entering the mouth and nose when worn at the mouth and nose positions so as to prevent harmful gases, smell and spray from entering and exiting the mouth and nose of a wearer, and is made of gauze or paper and the like. The mask has a certain filtering effect on air entering the lung, and has a very good effect when the mask is worn when the mask works in environments polluted by dust and the like during the flow of respiratory infectious diseases. The dust blocking efficiency of the mask is based on the dust blocking efficiency of the mask on fine dust, especially respiratory dust below 2.5 microns. Because the dust with the particle size can directly enter alveoli, the influence on human health is the greatest. The gauze mask has the dust blocking principle of mechanical filtration, namely, when dust collides with gauze, large-particle dust is blocked in the gauze through layer-by-layer blocking. For some fine dust, especially dust smaller than 2.5 microns, it passes through the mesh of the gauze and into the respiratory system. The gauze mask has poor adhesion with the face of a person, a plurality of tiny particles which are extremely harmful to people can enter the respiratory tract to the lung through gaps between the mask and the face, the filter material of the gauze mask is generally a plurality of mechanical fabrics, the filter material needs to be increased in thickness to achieve high dust blocking efficiency, the negative effect of the increased thickness is that a user feels great respiratory resistance and feel uncomfortable, and the mask can also produce a blocking effect on the exhalation of the user.

The existing mask is usually provided with a one-way valve which is conducted in the direction of expiration, and the one-way valve (or breather valve) of the mask is designed for facilitating breathing, and can be opened to allow air to be discharged from the mask during expiration. Its functions are to reduce the pressure inside the mask during breathing and to prevent the mask from becoming wet and reduce the resistance to exhalation. The check valve of the existing mask is complex in structure and high in cost, and the air outlet fixedly arranged on the check valve cannot adjust the air outlet direction and is easy to fog.

There is a need for a novel mask check valve structure that can address the above-described problems.
