Abstract

本实用新型涉及一种口罩,包括过滤层和固定带,所述过滤层的上边缘设有平行于上边缘的内衬层,所述内衬层与所述过滤层之间密封连接,所述内衬层为慢回弹性海绵。本实用新型一种口罩由于在过滤层的上边缘设有平行与上边缘的内衬层,且所述内衬层采用慢回弹性的海绵材料制成,佩戴口罩后,口罩上边缘会紧贴鼻子的边缘,使口罩密封严密。

Description

一种口罩
技术领域
本实用新型涉及口腔防护用品领域,特别是一种口罩。 
背景技术
现有的口罩都包括过滤层和固定带,由于固定层都是用纱布等柔性材料制成,因此当过滤层的上边缘盖住鼻子时,脸与鼻子之间会形成左右两个空隙,出现密封不严的问题;上述口罩用在防颗粒粉尘,空气过滤等场合,相当多的未经过滤的空气将会从上述空隙吸入口鼻,过滤效果很差。 
发明内容
为解决上述问题,本实用新型提供一种口罩。 
本实用新型采取如下技术方案: 
一种口罩,包括过滤层和固定带,所述过滤层的上边缘设有平行于上边缘的内衬层,所述内衬层与所述过滤层之间密封连接。
所述内衬层为慢回弹性海绵。 
由于以上技术方案的实施,本实用新型与现有技术相比具有如下优点: 
本实用新型一种口罩由于在过滤层的上边缘设有平行于上边缘的内衬层,且所述内衬层采用慢回弹性的海绵材料制成,佩戴口罩后,口罩上边缘会紧贴鼻子的边缘,使口罩密封严密。
附图说明
图1为本实用新型一种口罩结构示意图; 
其中1、过滤层;2、固定带。
具体实施方式
下面结合附图和实施例对本实用新型实用新型作进一步说明。 
如图1所示,一种口罩,包括过滤层和固定带,所述过滤层的上边缘设有平行于上边缘的内衬层,所述内衬层与所述过滤层之间密封连接。 
所述内衬层为慢回弹性海绵。 
由于以上技术方案的实施,本实用新型与现有技术相比具有如下优点: 
本实用新型一种口罩由于在过滤层1的上边缘设有平行于上边缘的内衬层3,且所述内衬层3采用慢回弹性的海绵材料制成,佩戴口罩后,口罩上边缘会紧贴鼻子的边缘,使口罩密封严密。
