摘要： A face mask structure has an upper mask portion, a middle mask portion, and a lower mask portion, which are formed integrally. The upper mask portion has an upper metal stripe disposed at a proper position thereof. The lower mask portion has a lower metal stripe disposed at a proper position thereof. The upper and lower mask portions are folded in opposite directions. When in use, the upper and lower mask portions are spread out to support the middle mask portion. In this way, the face mask structure becomes fitting in with the shapes of human faces. Furthermore, the middle mask portion has multiple folding portions. When in use, the folding portions are stretched out to increase filtering area. Thereby, the inner space of the face mask structure is increased, the air-invasion rate is reduced, and the filtering efficiency is thus improved.

摘要翻译：面罩结构具有一体形成的上掩模部，中间掩模部和下掩模部。上掩模部分具有设置在其适当位置的上金属条。下掩模部分具有设置在其适当位置的下金属条。上下掩模部分沿相反方向折叠。当使用时，上下掩模部分展开以支撑中间掩模部分。以这种方式，面罩结构变得适合人脸的形状。此外，中间的荫罩部分具有多个折叠部分。当使用时，折叠部分被拉伸以增加过滤面积。因此，面罩结构的内部空间增大，空气侵入率降低，因此提高了过滤效率。
