Respiratory mask with good sealing and comfort

A respiratory mask configured to enclose a user's nose and a user's mouth by forming a sealing area between a lower lip area and a nasal bridge area, or to enclose only the user's nose by forming a sealing area between an upper lip area and the nasal bridge area, wherein the respiratory mask is configured to supply pressurized respiratory gas to an airway of the user, the respiratory mask comprising:

• a first accommodation area configured to house the user's mouth and the user's nose or only the nose, the first accommodation area communicating with an inner cavity of the rigid component, and the first accommodation area having a side of the elastic component that is closest to the rigid component fixedly connected to the joint part,
• a pressing part configured to seal at least a portion of the user's nose on a side of the elastic component that faces away from the rigid component, and
• an annular comfort layer configured to seal at least part of the face of the user when in use, the annular comfort layer including:
• a second accommodation area configured to house the user's mouth and the user's nose or only the nose, the second accommodation area being connected to the first accommodation area,
• wherein the annular comfort layer is fixedly connected to the side of the elastic component facing away from the rigid component and covers at least part of the pressing part, and is configured to form a sealed surface that contacts the face of the user together with the elastic component within the interior of an inner edge of the annular comfort layer;
• wherein the annular comfort layer is made of foam material;
• wherein the annular comfort layer includes a first surface configured to be in contact with the face of the user and a second surface connected to the elastic component, with an angle α between the first surface and the second surface being at or between 0 to 80 degrees;
• wherein the annular comfort layer is configured to include a density at or between 10 to 200 kg/m3;
• and
• wherein the annular comfort layer is configured to include a ratio of a width to a height at or between 0.1 to 30.

A respiratory mask configured to enclose a user's nose and mouth by forming a sealing area between a lower lip area and a nasal bridge area, or to enclose only the user's nose by forming a sealing area between an upper lip area and the nasal bridge area, wherein the respiratory mask is configured to supply pressurized respiratory gas to an airway of the user, the respiratory mask comprising:

• a rigid component comprising:
• at least one gas delivery interface at a side configured to be farthest away from a face of the user, and
• an annular interface at a nearest side of the rigid component configured to be closest to the face of the user configured to form a joint part along an outer edge of the annular interface;
• an elastic component, configured to adjust a distance between the rigid component and the face of the user, the elastic component including:
• a first accommodation area configured to house the user's mouth and the user's nose or only the nose, the first accommodation area communicating with an inner cavity of the rigid component, and the first accommodation area having:
• a side of the elastic component closest to the rigid component fixedly connected to the joint part, and
• a side of the elastic component facing away from the rigid component having a non-thin area and at least one thin area, with a wall thickness of the thin area being at or between 0.2 to 2 mm;
• an annular comfort layer configured to seal at least part of the face of the user when in use, a portion of the elastic component being configured to contact the face of the user within the interior of an inner edge of the annular comfort layer, the annular comfort layer including:
• a second accommodation area configured to house the user's mouth and the user's nose or only the nose, the second accommodation area being connected to the first accommodation area,
• wherein the annular comfort layer is fixedly connected to the side of the elastic component that faces away from the rigid component and covers at least part of the elastic component;
• wherein the annular comfort layer made of at least one absorbent material;
• wherein the annular comfort layer includes a first surface that is configured to contact the face of the user and a second surface that connects to the elastic component;
• wherein the distance variation between the first surface of the annular comfort layer and the rigid component is to yield at least two different values when applying a same force in a constant direction to different positions of the annular comfort layer;
• wherein the annular comfort layer is configured to include a density at or between 10 to 200 kg/m3;
• and
• wherein the annular comfort layer is configured to include a ratio of a width to a height at or between 0.1 to 30.
