Embodiment Construction

[0015] exist figure 1 In the embodiment shown, the mask sealing protective cover is mainly composed of an approximately annular frame (1), a strap (3) for fixing on both sides of the frame, and an inflatable air bag (2) attached to the frame. (2) After inflation, an approximately annular hose appears. The airbag hose (2) is located between the frame and the mask when the present invention is used, and the mask is compressed around the mask so that the surrounding area can be well fitted to the user's face. Some parts of the frame (1) can be made of hard materials such as hard plastics, and some parts are made of materials with better deformability such as deformable metal bead, so that the frame (1) can maintain a good fixed shape during use. It can also adjust the shape of the nose bridge and other parts by the user, and is easy to fold. The airbag hose (2) can be made of light and airtight materials such as polyvinyl chloride film, and is provided with an openable and clos...

Abstract

The invention relates to a sealed protective cover for a mask, which overcomes the defects that the existing masks have weak gastightness or expensive construction cost, and are difficult to repeatedly use and the like. The sealed protective cover is provided with a fixed device, a respirator fabric and a soft object which can generate deformation when the sealed protective cover clings to a face and externally press the respirator fabric, which is close to the skin and at the inner side of the sealed protective cover, at the periphery of the region containing nostrils or a mouth and a nose, and the region and the outside are separated by the respirator fabric at the moment. The externally pressed respirator can be classified into main two major schemes: a novel nose mask and the sealed protective cover for the mask. Generally, the novel nose mask and the sealed protective cover for the mask are provided with a gas dag or a liquid bag or other flexible materials having certain elasticity as a press device therein.

Description

Technical field [0001] The invention relates to a sealing protective cover for a mask. Background technique [0002] At present, the air tightness of ordinary masks around them is not strong, resulting in poor protection ability. While other high-end masks have deformable metal strips at the bridge of the nose, it is still difficult to achieve a good fit on the user's full face, and high-end masks are expensive, difficult to promote, and difficult to use multiple times. SUMMARY OF THE INVENTION [0003] In order to overcome the shortcomings of the above-mentioned masks such as poor air-tightness, high cost, and difficulty in repeated use, the present invention provides a mask sealing protective cover, which is a portable and lightweight protective cover that provides sealing protection or fixing for various masks or mask filter fabrics. appliance. [0004] The technical scheme adopted in the present invention is: [0005] The mask sealing protective cover is mainly comp...
