Abstract
A comfortable, well-sealing respiratory mask with an annular comfort layer. The respiratory mask includes a rigid component, an elastic component, and an annular comfort layer. The rigid component is equipped with a gas delivery interface and an annular interface; the elastic component is connected to the rigid component and features a first accommodation area designed to house the user's mouth and nose or only the nose. On one side of the elastic component far away from the rigid component, there is at least one pressing part designed to seal at least a portion of the user's nose; the annular comfort layer has a second accommodation area that communicates with the first accommodation area, covering at least part of the pressing part and jointly forming a sealed surface with the elastic component.
