Abstract

Disclosed are a liner for a breathing mask and the breathing mask. The liner comprises a connection portion used for connecting the liner onto a frame or an elbow component of the breathing mask, a face contact portion used for contacting the face of a patient and formed by thin films and a support portion connected between the connection portion and the face contact portion, wherein at least a part of the face contact portion is provided with an outward extension portion extending from the support portion to the exterior of the liner and an inward extension portion extending from the periphery of the outward extension portion to the interior of the liner. Two seal areas are formed on the liner through the face contact portion so as to generate reliable sealing, and therefore ideal sealing effects can be achieved by applying low support force, and then wearing comfort is improved.
