Embodiment Construction

[0014] Such as figure 1 Shown a kind of three-dimensional mouth mask, comprise mouth mask body 1 and be positioned at the elastic elastic earband 2 of mouth mask body 1 both sides, described mouth mask body 1 has the three-dimensional structure that is pressed by left half and right half, so The inner and outer layers of the mask body 1 are non-woven fabric layers, and the mask body 1 includes an outer non-woven fabric layer 3, a high-efficiency filter layer 4, an antibacterial layer 5 and an inner non-woven fabric layer from outside to inside. 6. The outer non-woven fabric layer 3, the high-efficiency filter layer 4, the antibacterial layer 5 and the inner non-woven fabric layer 6 are pressed into an integral structure. The high-efficiency filter layer 4 is provided with folding lines 7 . The folds 7 cover the entire high-efficiency filter layer 4 . The high-efficiency filter layer 4 is an activated carbon fiber material layer. The elastic elastic ear strap 2 has a connect...

Abstract

The invention discloses a stereo mask comprising a body and elastic ear bands on two sides of the body. The body is in the stereo structure formed by compressing a left portion and a right portion. An inner layer of the body and an outer layer of the body are both made of non-woven fabric. The body comprises an outer non-woven fabric layer, an efficient filtering layer, an anti-bacteria layer and an inner non-woven fabric layer which are integrated from outside to inside. According to the arrangement, the anti-bacteria layer is arranged on the inner layer to avoid stimulation and sensitization to human body; by the aid of fold-line creases arranged in the efficient filtering layer, airflow velocity is reduced, and accordingly filtering efficiency is increased; due to the stereo structure, the nose of the user doesn't directly contact the mask, thus avoiding stuffiness; bacteria, flu and PM 2.5 are isolated.

Description

technical field [0001] The invention relates to a three-dimensional mask. Background technique [0002] A mask generally refers to a device worn on the mouth and nose to filter the air in the mouth and nose, so as to block harmful gases, odors, and droplets from entering and leaving the wearer's mouth and nose. It is mostly made of cloth or paper. The existing masks have a simple structure, are airtight, have low filtering effect, are easy to make people feel uncomfortable, and cannot prevent the harm of influenza germs and PM2.5. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned technical problems, the present invention provides a three-dimensional mask, which can completely solve the above-mentioned technical problems. [0004] The technical scheme that solves the above-mentioned technical problem is as follows: [0005] A three-dimensional mask, comprising a mask body and elastic ear straps positioned on both sides of the ...
