Description

Double-skirt-edge respirator support

Technical Field

The utility model relates to a gauze mask technical field, in particular to two shirt rim respirator support.

Background

The existing three-dimensional respirators (respirator gas masks) are generally classified into two types, one type of structure is as follows: take three-dimensional rigid support of breathing gas vent class triangle-shaped toper and inhale the filter, expiration hole department integrated into one piece has one-way exhaust valve seat for installation membrane valve block and valve gap, inspiration hole department integrated into one piece have the mount pad to detain and be used for installing the filter of breathing in, flexible glue border inside bend, the lateral surface laminating face nose bridge lip region on this flexible glue inside bend border plays sealed effect. The other type of structural component is a triangular-cone-shaped integral soft rubber support with a breathing air hole, a rigid outer support, an air suction filter and a one-way exhaust valve, the edge of the soft rubber support is bent inwards, the outer side surface of the edge of the soft rubber bent inwards is attached to the lip region of the nose bridge of the face to play a sealing role, the soft rubber support is embedded on the rigid outer support to increase the supporting rigidity, and the air suction filter valve and the one-way exhaust valve are installed on a support hole.

Above-mentioned three-dimensional respirator (gauze mask respirator), the whole three-sided toper of class of support, the top point is protruding in order to laminate the bridge of the nose, and whole support bottom surface border curvature shape is similar to bridge of the nose lip region, and soft glue material border is added, and sealed effect is more effectual than general gauze mask, but still has the leakproofness problem inadequately: because the support is rigid, the shape is fixed, and different people's face nose bridge lips shape is different, leads to support flexible glue border curvature can not accomplish the laminating of people, leads to the leakproofness variation.

The inventor researches the respirator support with double skirts to improve the tightness of the respirator and prevent unfiltered air from directly entering the respiratory system of a human body from the edges of the respirator.
