Abstract

本实用新型是一种口罩,由纱布、泡沫构成,其特征是,在两层纱布的口罩上部中间,分别设有由纱布包裹的两块泡沫。该口罩,既经济又实用,尤其适用于粉尘较大的生产车间,是一种全封闭式安全口罩。

Description

一种口罩
技术领域:
本实用新型涉及劳动保护用品,具体地说是一种口罩。
背景技术:
目前,商场所出售的口罩,由于人的鼻子突出高于脸面,人戴上口罩时,鼻子两侧会出现两道空隙,这样就为粉尘进入口罩创造了方便的通道,尤其是在粉尘较多的车间工作,工人尽管戴着口罩,但粉尘也照样通过鼻、口腔进入体内,这时口罩并设能真正起到对人体防尘的保护作用。
发明内容:
本实用新型的目的在于,设计出一种结构科学、方便实用、安全可靠、防止灰尘通过鼻、口腔进入体内的口罩。其技术内容是,一种口罩,由纱布、泡沫构成,其特征是,在两层纱布的口罩上部中间,分别设有由纱布包裹的两块泡沫。本实用新新型和现有技术相比其先进之处在于,一种口罩,具有设计合理,使用方便,密封性能好的特点,从而克服了现有口罩对粉尘密封不严的不足之处。
附图说明:
本图为本实用新型外观立体局剖结构示意图;
其中,纱布1、泡沫2、纱布口罩3。
具体实施方式:
下面结合附图对本实用新型再作进一步地描述,在两层纱布的口罩3上部中间,分别设有由纱布1包裹的两块泡沫2,以上便构成本实用新型。
