Abstract

本实用新型公开了一种低呼吸阻力防尘口罩，包括棉纱体1和系带2，该棉纱体1内设置网状外凸结构的弹性支撑架3。此种结构的防尘口罩呼吸阻力小。

Description

低呼吸阻力防尘口罩
技术领域
本实用新型涉及一种口罩，特别是一种低呼吸阻力的防尘口罩。
背景技术
现有防尘口罩通常为棉纱口罩，呼吸时口罩容易贴附在口鼻上，使用过程中呼吸阻力大，在粉尘大及湿度增加的情况下，呼吸阻力更大。
发明内容
本实用新型的目的在于提供一种克服上述缺点、能有效减小呼吸阻力的低呼吸阻力防尘口罩。
本实用新型是这样实现的：一种低呼吸阻力防尘口罩，包括棉纱体和系带，该棉纱体内设置网状外凸结构的弹性支撑架。
通过设置外凸弹性支撑架，使用过程中，口罩不会贴附在口鼻上，能有效减小呼吸阻力。
附图说明
图1为本实用新型的剖视示意图。
图2为图1的俯视图。
具体实施方式
如图所示，本实用新型包括棉纱体1、系带2和弹性支撑架3，弹性支撑架3为网状外凸结构，设置在棉纱体1内。使用时，由于设置了支撑架3，口罩离口鼻有一定间隙，不会吸附在口鼻上，能有效减轻呼吸阻力。
