Description

防尘口罩
技术领域
本实用新型涉及一种口罩，具体涉及一种防尘口罩。
背景技术
防尘口罩是为了防止或减少空气中粉尘进入人体呼吸器官从而保护生命安全的个体保护用品。目前的防尘口罩大多采用内外两层无纺布，中间一层过滤布构造而成。在低温灰尘较多的环境下，佩戴眼镜的从业人员带这种防尘口罩时，镜片容易起雾，粘上灰尘遮挡视线，而且不便清除，影响从业人员的人身安全和工作效率。针对上述问题，本领域的人员对眼镜片起雾的原因进行了分析，主要是因为防尘口罩在鼻翼处漏气严重。
实用新型内容
本实用新型针对上述不足，设计了一种结构简单、使用方便的防尘口罩，从业人员通过佩戴这种防尘口罩可以有效的解决眼镜片起雾的问题，避免镜片粘上灰尘，遮挡视线。
本实用新型采用的技术方案是：
一种防尘口罩，包括外层、内层、口罩带，其特征在于：所述内层上半部材质为塑料薄膜，内层与鼻翼接触的部位设有密封带。
所述密封带为纱布。
所述口罩带为弹性带。
本实用新型的有益效果：
本实用新型结构简单、使用方便，通过佩戴本实用新型能够有效的防止眼镜片起雾，消除因眼镜片起雾造成视线不清带来的安全隐患。
附图说明
图1为本实用新型防尘口罩的侧视图。 
图2为防尘口罩的内层结构示意图。
其中：1、外层；2、内层；3、口罩带；4、密封带；5、内层上半部。
具体实施方式
下面结合附图和具体实施方式对本实用新型做进一步的描述。
如图1及图2所示，一种防尘口罩，包括外层1、内层2、口罩带3，所述内层上半部5材质为塑料薄膜，内层2与鼻翼接触的部位设有密封带4，所述密封带4为纱布，口罩带3为弹性带。
使用过程：
从业人员佩戴此口罩时，将口罩带3挂在耳朵上或者缠绕在头部，防尘口罩的内层2与人体面部紧密接触，密封带4与面部鼻翼处紧密接触，使得呼出的热气从密封带4的底部流出，避免镜片起雾，从而有效避免灰尘粘上镜片遮挡视线。经试验，相同环境下使用普通口罩大约10分钟左右就要清理镜片，而采用本口罩一般连续使用一个小时以上才需要清理。
