High-fitting-degree three-dimensional filtering mouth mask

Abstract

The invention relates to a high-fitting-degree three-dimensional filtering mouth mask. The mouth mask comprises a mouth mask body (1), hanging belts (2) are arranged on the left side and the right side of the mouth mask body (1), the mouth mask body (1) comprises a gauze layer (1.1) and a filtering layer (1.2) which are sequentially arranged from inside to outside, a supporting cover (3) is arranged in the middle of the mouth mask body (1), the shape of the supporting cover (3) is matched with that of the tip of the nose, and the periphery of the mouth mask body (1) is provided with a fitting edge (4). The mouth mask body of the high-fitting-degree three-dimensional filtering mouth mask comprises two layers of structures, and the mouth mask is good in air permeability and moisture absorption and can filter away dust and bacteria in air; the mouth mask body is closely attached to the outline of the tip of the nose and the face, outside viruses and bacteria are effectively isolated, and lenses of a doctor can be prevented from being dimmed by vapor in the mouth.

Description

technical field [0001] The invention relates to a mask, in particular to a high-fit three-dimensional filter mask. Background technique [0002] Existing masks generally consist of a cover and a lanyard. When it is buckled at the mouth and nose, due to the bulge of the nose, the joint between the cover and the contour of the nose and the face is not tightly closed, forming an air passage. During protection, viruses and bacteria can easily enter through this channel, which fails to meet the requirements of isolating viruses and bacteria. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, and provide a high-fit three-dimensional filter mask, which can make the mask body closely combined with the nose contour and face, and effectively isolate external viruses and bacteria. [0004] The object of the present invention is achieved like this: a kind of high fitting three-dimensional filter mouth mask, it comp...
