Mask capable of conveniently replacing filter element

Abstract

The invention relates to a mask capable of conveniently replacing a filter element. A filter element mask body is in a concave shape, an elastic sealing strip facing the concave face is arranged at the edge of the formed concave face, a supporting body is in the shape matched with the filter element mask body, a hollowed part is formed on the supporting body, the supporting body is arranged insidethe filter element mask body, covered with the elastic sealing strip and used for supporting the filter element make body and enabling the filter element mask body to form the filter element, a connecting piece parent body is arranged at the outer side face of the supporting body, connecting piece son bodies are arranged at the two ends of a connecting belt, and the connecting belt is connected to the supporting body by connecting the connecting piece son bodies and the connecting piece mother body. The mask has the advantages that difficult breathing and stuffiness are avoided, the whole filter element mask body is the filter element, the supporting body opens the filter element mask body to reserve the space with respiratory organs and skin, the wearing comfort is greatly improved, andcontact between dust and bacteria and the filter element mask body is lowered.
