Description

可换防毒滤料的防护口罩
本实用新型涉及一种滤毒防护口罩,特别是可换滤毒材料的防护口罩。
现有的阻菌滤毒防护口罩主要有全纸型单层活性碳滤料口罩,这种口罩使用时口罩对人体脸部密封不严密,常有漏气的缝隙,不能完全过滤呼吸时吸入的空气,带菌和带毒的气体仍从漏气缝隙进入呼吸道。1994年6月1日实用新型公告了一种名称为“阻菌滤毒防护面罩”公告号CN2166835Y,是将阻菌滤毒的活性碳滤料由不锈钢网夹紧与橡胶面托密封为一体,这种阻菌滤毒防护面罩虽然克服了面罩与人体脸部存在漏气缝隙的不足,但是活性碳滤料的清洁,再活化受到了与其为一体的橡胶面托不能耐高温的限制。
本实用新型是要克服上述已有的技术不足,而提供一种既能与人体脸部密封又能拆御滤毒活性碳纤维毡滤料,拆御下来的滤毒活性碳纤维毡滤料可以清洗,也可以再活化重新使用,还可以更换新的滤毒活性碳纤维毡,使防护口罩的滤毒能力得于保持。
本实用新型是这样的实现的:采用柔性塑料制成能与人体脸部密封型状夹罩,分内夹罩和外夹罩结构,内夹罩与外夹罩采用凸钉式扣入扣孔的方式固定,内夹罩与外夹罩之间置放活性碳纤维毡滤毒材料,由内、外夹罩夹紧密封固定,夹罩的周边嵌镶泡沫海棉密封条,当使用时泡沫海棉密封条既可起到密封作用,又改善了舒适性能,内、外夹罩都加工成栅格式,既可固定夹紧其间的活性碳纤维毡又有较好的通气性能,外夹罩两端都开有系带固定的长型孔,穿入系带即可按不同头型的人使用时调节到适宜的紧松要求。
以下结合附图作进一步祥细说明:
图1是本实用新型可换防毒滤料的防护口罩的主视图;
图2是本实用新型可换防毒滤料的防护口罩的剖视图;
图3是本实用新型可换防毒滤料的防护口罩的俯视图;
图4是本实用新型可换防毒滤料的防护口罩的凸钉示意图;
结合附图内夹罩(7)与外夹罩(9)由凸钉(2)扣入扣孔锁紧,使之夹紧置入放在内夹罩(7)与外夹罩(9)之间的活性碳纤维毡滤料(8),拉开锁紧内、外夹罩(7)(9)的凸钉(2)即可取出活性碳纤维毡滤料(8)清洁或活化处理,处理后重新装入夹罩即可再使用,也可更换新的活性碳纤维毡滤料(8),在内、外夹罩(7)、(9)的周边嵌镶泡沫海棉密封条(6)使之与人体脸部更好密封,并且又改善了佩戴的舒适性。外夹罩(9)的边(5)的两端还开有固定系带的长型孔(1),内夹罩(7)外夹罩(9)都开有栅格孔(3)间是栅格筋(4),使之既能夹紧活性碳纤维毡滤料(8)又具有较好的通气性能。

Claims (1)
