Abstract

The invention discloses a separable mask with an internal arching strip. The separable mask comprises mask cloth and bands for fixing the mask cloth, and is characterized in that an annular interlayer is arranged on the inner side of the mask cloth, the inner circumference of the interlayer is separated from the mask cloth, the interlayer is provided with an annular connecting line for connecting the interlayer with the mask cloth, and the connecting line is located on the outer side of the portion, separated from the mask cloth, of the interior of the interlayer to accordingly form a groove with an inwards-opened opening; a pressing piece is arranged and matched with the groove in size and shape to accordingly enable a part of the edge of the pressing piece to be installed in the groove, and separable connection with the mask cloth or the interlayer is accordingly achieved; the pressing piece is provided with a strip-shaped body arching towards the region, surrounded by the groove and located in front of the mouth or the nose, of the mask cloth, and the mask cloth is ejected through the strip-shaped body from the region, in front of the mouth or the nose, of the inner side of the mask cloth. Materials can be saved, the air impermeability can be improved, the effective air inspiration breathable area of the mask can be increased, the comfort of the mask can be improved, and the separable mask is healthier.

Description

Technical field [0001] The invention relates to a detachable mask with inner arched strips. Background technique [0002] At present, the airtightness of ordinary masks around them is not strong, resulting in weak protective capabilities.
