【技术实现步骤摘要】
一种主动式送风电动口罩
本技术涉及人体呼吸防护口罩产品领域,特别涉及一种主动式送风电动口罩。
技术介绍
在工作场所比如焊接工作环境,烟雾比较浓,喷涂行业、抛光打磨工作、石材加工等,都处于粉尘多且含有毒有害气体的工作环境,都需要带着口罩。而且近年来,由于空气质量恶化,雾霾现象出现增多且危害加重,人们出行经常都带着口罩。目前市场上的口罩种类繁多,普通口罩,在阻挡较大微粒时有用,主要是防尘功能。近几年来北方出现严重的雾霾天气,人们出门在外不戴个口罩怎么安心,然而,对于传统口罩而言,根本无法抵挡PM2.5。而市场上出现的更高级别的防雾霾口罩,说是可以达到国家标准(KN90、KN95、KN100三个等级),但是,真正能有效过滤PM2.5的净化效果十分有限。其主要有几个弊端:1.普通口罩由于结构,布料及穿戴方式的原因,造成不能与人体面部到达100%的紧密贴合,密闭性差,呼吸时就难免会吸人没有经过有效过滤的空气。2.普通口罩因呼吸阻力大,不能长时间佩戴,特别是呼吸困难人群和皮肤过敏人群。3.普通口罩防护级别越高,材料的风阻就越大,呼吸阻力就越大,容易造成气闷,呼吸困难,不舒服。 ...
