Description

The present invention addresses the field of protective equipment, and in particular, is a multi-stage disposable mask.

When using a traditional disposable mask, the internal filter filters the air directly when used, and since the area of the mask is large, the moisture in the air is absorbed by the cotton layer inside the mask, and the dry air is sucked in the human respiratory tract. Disadvantageous for gas circulation. Also, traditional disposable masks do not allow different groups of people to vary the amount of air suction, and for children and the elderly, reducing the amount of air suction can increase air filtration efficiency differently. Therefore, it is necessary to design a multi-stage adjustable disposable mask to solve the above drawbacks.
