所述的呼吸过滤器总成本体的大直径圆筒的筒壁底部制作有卡扣和 弧形卡凸； 筒壁顶部的外缘上开有定位口。
本发明与现有技术相比的有益效果在于：
该呼吸阀同轴带呼气通道的过滤器总成将吸气阀和呼气阀采用同轴 安装， 小直径圆筒的底部制作有专用的呼气通道， 缩短了呼吸循环通道 的距离， 实现了防尘防毒面罩呼吸气时顺畅， 体积小、 重量轻、 面罩佩 戴舒服、 不易滑落的目的。 且结构简单， 无需开制多个呼气通道， 降低 了模具制造和注塑时的加工难度， 有效提高了面罩整体的密闭隔绝性。 解决了现有面罩的呼气阀、 吸气阀不同轴安装， 呼气阀不能正对嘴部呼 气产生憋闷感， 且体积和重量大， 佩戴时易滑落的问题， 适合所有防尘 防毒场所的面罩使用。 附图说明：

图 2为一种呼吸阀同轴带呼气通道的过滤器总成去掉阀片挡圈后的 图 3 为一种呼吸阀同轴带呼气通道的过滤器总成安装在面罩上的结 构示意图。
图中： 1、 呼吸过滤器总成本体， 2、 环形单向阀瓣， 3、 圆片单向 阀瓣， 4、 阀片挡圈， 5、 卡扣， 6、 加强筋， 7、 定位口， 8、 弧形卡 凸， 9、 芯轴， 10、 呼气通道， 11、 0型圈， 12、 过滤棉。
具体实施方式：
该呼吸阀同轴带呼气通道的过滤器总成由呼吸过滤器总成本体 1、 环形单向阀瓣 2、 圆片单向阀瓣 3和阀片挡圈 4构成， 呼吸过滤器总成 本体 1 为两个同轴的一大一小的圆筒构成， 圆筒的顶部为开口状， 圆筒 的底部开口上制作有加强筋 6， 两个大小圆筒由底部的加强筋 6连接， 小直径圆筒中心通过加强筋 6 固定有一芯轴 9。 所述的小直径圆筒的芯 轴 9上套装有一圆片单向阀瓣 3， 圆片单向阀瓣 3放置在小直径圆筒底 部的加强筋 6上， 小直径圆筒的顶部卡装有一阀片挡圈 4， 小直径圆筒 的底部制作有专用的呼气通道 10。 所述的大直径圆筒内套装有一环形单 向阀瓣 2， 环形单向阀瓣 2放置在大直径圆筒底部的加强筋 6上， 圆片 单向阀瓣 3和环形单向阀瓣 2安装放置后为同轴状态。
所述的圆片单向阀瓣 3和环形单向阀瓣 2均为单向过滤阀片， 圆片 单向阀瓣 3只能单向呼出空气， 不能吸入空气； 环形单向阀瓣 2只能单 向吸入空气， 不能呼出空气。 所述的呼吸过滤器总成本体 1 的大直径圆 筒的筒壁底部均布制作有八个卡扣 5和弧形卡凸 8; 筒壁顶部的外缘上 开有定位口 7 (参见附图 1〜2) 。
该呼吸阀同轴带呼气通道的过滤器总成可与各种防尘防毒面罩配 套， 使防尘防毒面罩的体积减小， 重量减轻， 并能缩短呼吸循环通道的 距离， 呼吸过滤器总成的前面还可以根据需要设置多重过滤装置。 附图 3为该呼吸阀同轴带呼气通道的过滤器总成安装后的一种结构。
该呼吸阀同轴带呼气通道的过滤器总成的工作原理为 （以附图 3 为 例） ， 先通过扣带将面罩戴在口鼻上， 外面的空气通过过滤棉过滤后， 再通过环形单向阀瓣 2吸入口腔内。 循环后产生的二氧化碳等废气经圆 片单向阀瓣 3 呼出， 再经呼气通道 10排出， 为了确保吸入和呼出的气 体不串通， 吸气道和呼气道之间采用了 0 型圈 11 隔离。 由于环形单向 阀瓣 2和圆片单向阀瓣 3安装后为同轴状态， 圆片单向阀瓣 3正对人体 的嘴部， 因此使得呼吸循环过程缩短， 保证了使用者呼吸顺畅， 不憋 闷， 佩带舒适。 本发明将吸气阀 1与呼气阀 2同轴装接， 无需多开呼气 通道， 使面罩的密闭隔绝性得到极大提高。 同时， 呼气通道减少后， 相 应配件就少， 有效减轻了面罩的整体重量， 适合长时间佩带不滑落， 不 会产生夹疼等不舒服感， 提高了使用效率， 降低了制造成本。
