目前多层口罩主要由一层以上的过滤材料构成，目前的多层口罩主要由一层以上的过滤材料先叠合再整体折叠构成，能起过滤颗粒物和细菌病毒的作用，保护人体健康；特别是一次性的方形平面口罩在生产生活中应用广，需求大，一次性的方形平面口罩一般是多层叠合后，再折叠，如一次性医用口罩；折叠的作用主要是，拉伸折叠部分后，口罩能更好的遮挡覆盖口鼻，更好的过滤吸入的空气。At present, multi-layer masks are mainly composed of more than one layer of filter materials. The current multi-layer masks are mainly composed of more than one layer of filter materials first stacked and then folded as a whole, which can filter particles and bacteria and viruses, and protect human health; especially Disposable square flat masks are widely used in production and life and have great demand. Disposable square flat masks are generally stacked after multiple layers and then folded, such as disposable medical masks; the main function of folding is to stretch the folded part. , The mask can better cover the mouth and nose, and filter the inhaled air better.
技术问题technical problem
口罩在使用一定的时间后，由于各种颗粒物、细菌和病毒，以及水分子逐渐堵塞过滤材料的过滤孔，特别是先堵塞呼吸道口前面过滤材料的过滤孔，导致口罩的空气通过效率下降，单位时间内通过口罩进入呼吸道的空气减少；特别是在空气质量差或运动时吸气，口罩过滤空气量不足以满足需求量，导致口罩两面的压差加大，大气压力使口罩贴近呼吸道口，人会感到呼吸困难，严重时会使人缺氧导致伤害；为了解决上述难题，本 实用新型提出单层折叠多层口罩，把单层过滤片先折叠，再把多层过滤片叠合在一起，改善口罩内部的结构，增加口罩的抗变形能力，增加口罩内部的层间空隙。 After the mask is used for a certain period of time, due to various particles, bacteria, viruses, and water molecules, the filter holes of the filter material are gradually blocked, especially the filter holes of the filter material in front of the respiratory tract mouth are blocked first, resulting in a decrease in the air passing efficiency of the mask. The amount of air entering the respiratory tract through the mask is reduced within a period of time; especially when the air quality is poor or inhalation during exercise, the amount of filtered air by the mask is not enough to meet the demand, which causes the pressure difference between the two sides of the mask to increase, and atmospheric pressure makes the mask close to the mouth of the respiratory tract. will experience difficulty in breathing, lead to severe injury resulting in hypoxia; to solve the above problems, the present invention proposes single-folded multi-layer masks, the first single-piece folding filter, then a multi-layer filter were stacked together, Improve the internal structure of the mask, increase the anti-deformation ability of the mask, and increase the gap between the layers inside the mask.

The ear ropes 1 are fixed on the side of the filter body with folding gaps, and the single-layer filter sheets on the four sides of the filter body 2 Closed and combined together, the single-layer filter sheet in the filter body 2 forms a cavity gap between the layers; the folding shape of the single-layer filter sheet of the single-layer folded multi-layer mask is the same as the folded shape of a common disposable medical mask The filter body 2 is first folded and then laminated by two or more single-layer filter sheets, the four sides of the filter body are closed and joined together, and the combination method is welding or seaming, or bonding; the single-layer folded multi-layer mask Its characteristic is: the filter body 2 is a filter body composed of two or more layers of folded single-layer filter sheets and then closed and combined between four sides; when the single-layer filter sheet of the filter body is three-layer, four-layer or five-layer The effect is better.
有益效果Beneficial effect
本 实用新型与普通的多层平面折叠口罩相比较，优点一，是把单层先折叠再叠合形成的较蓬松的结构，增加了口罩的层间空隙，当拉伸口罩的折叠部分，人戴上口罩时，使增加的口罩层间空隙更明显，增加的空隙容纳了更多的空气，吸气瞬间的吸气量增加，层间空隙起到了类似储气罐的储气稳压作用，增加口罩的层间空隙增大了稳压作用，吸气时延缓了口罩两面的压差下降；优点二，单层先折叠后再叠合时大于多层叠合再折叠时，分散的折叠边使口罩在呼吸时抗变形的增强，在恶劣环境或口罩长时间使用后，能较充分利用口罩靠近耳带端过滤体的过滤能力；优点三，没增加材料，只是改变口罩的加工工序，实现低成本的提高口罩的性能。 Present invention compared with the conventional multi-layer flat folded masks, one advantage is the relatively bulky single folded first and then laminated structure is formed, an increase of the interlayer gaps mask, the folded portion when stretched masks, human When wearing a mask, the increased gap between the layers of the mask is more obvious. The increased gap contains more air, and the amount of inhalation at the moment of inhalation increases. The gap between the layers acts as a gas storage and stabilizing effect similar to that of an air tank. Increasing the gap between the layers of the mask increases the voltage stabilization effect, and delays the drop in the pressure difference between the two sides of the mask when inhaling; the second advantage is that when a single layer is folded first and then stacked, it is larger than when a multi-layer stack is folded again. The scattered folding edges make The mask’s resistance to deformation during breathing is enhanced. In harsh environments or after a long period of use of the mask, the filter capacity of the mask near the earband end can be fully utilized; advantage three, no material is added, only the processing procedure of the mask is changed to achieve low The cost of improving the performance of the mask.
