Document Type and Number:
WIPO Patent Application WO/2022/056768
Kind Code:
A1
Abstract:
A moisture-proof face mask, comprising a face mask body (1), wherein the face mask body (1) is composed of a non-woven fabric inner layer (7) and a water-proof outer layer (5); the non-woven fabric inner layer (7) and the water-proof outer layer (5) enclose a hollow cavity body; and a filter layer (8) is placed in the hollow cavity body. The water-proof outer layer (5) is provided with a plurality of ventilation holes (6) arranged side by side. A mesh bag (2) is provided on the non-woven fabric inner layer (7), and a hydrophilic cotton piece is placed in the mesh bag (2). In the face mask, the hydrophilic cotton piece quickly absorbs moisture on the inner side of the face mask that is breathed out by a person when he/she is wearing the face mask, so that the inner side of the face mask remains dry and fresh; in addition, air entering the face mask is purified and filtered by means of providing the filter layer (8) in a cavity between the inner layer and the outer layer. Finally, the breathability of the face mask is improved by means of providing the ventilation holes (6) in the outer side of the face mask.
