Abstract
The present invention provides a mask structure, which comprises a first mask body, a main filtering layer, an air-isolator, and a second mask body. The main filtering layer is disposed at the first mask body. The area of the main filtering layer is smaller than the area of the first mask body. The air-isolator is disposed at the first mask body and adjacent to the periphery of the main filtering layer. The second mask body covers the main filtering layer and the air-isolator and is bonded with the air-isolator and the first mask body. Thereby, the bonding part of the mask structure can be tight and the filtering materials of the main filtering layer, such as sterilizing or adsorptive materials, will not leak from the bonding part. In addition, the air-isolator can guide the air inside and outside the mask structure to pass only through the main filtering layer for preventing the polluting particles, bacteria, or viruses inside and outside the mask structure from being propagated to the external environment or inhaled by the user.
