防毒面具和防颗粒物呼吸器及其制造方法 技术领域
本发明涉及一种呼吸防护面具，属于特种劳动防护用品技术领域，具体是一种防毒面具和防颗粒物呼吸器及其制造方法。
背景技术
目前特种劳动防护用品使用传统的防毒面具是由面具主体、过滤盒、呼气阀和系带组成，面具与人体面部接触的密封垫圈是同面具主体相同的材料弯卷边而成的，佩戴时面具主体太软会变形，密封垫圈是单层橡胶模压弯卷边而成，材料柔软性差，密封垫圈与人体面部接触处的壁相对较厚，对人体面部各部位的压力同等，使用者长时间佩戴会对面部有些部位有压迫感，并会在面部留下压痕，佩戴的舒适性不好；另一方面防毒面具配套过滤吸附有毒气体功能的是过滤盒，过滤盒只能从过滤盒口一面(单方向)吸进空气，过滤盒内填装的是活性炭颗粒，依靠活性炭颗粒过滤吸附有毒气体，在该过滤盒内活性炭层的内底层和外顶层只能设放的是初效过滤棉，对防护微小的颗粒物功能较差，如想放置高效过滤棉，因过滤盒只能从过滤盒口一面吸进空气，吸进空气的通气面积有限，那吸气阻力太大又不行；目前防毒面具配套的过滤盒只是单一的防护有毒气体的功能，不能高效防护微小颗粒物的功能，过滤盒内填装的是活性炭颗粒重量比较重，又加上过滤盒外壳的自身重量，那过滤盒的整体重量太重了，对使用者长时间佩戴会感觉到下坠的不舒适感；为此本人在2009年11月29日向国家知识产权局申请了专利号：200910154351.7的发明专利，上述专利相对目前传统防毒面具主要改进的是将直接与面部接触的密封垫圈的材质与面具主体的材质区别，密封垫圈为敞开式的橡胶件黏合而成的橡胶气囊密封垫圈，气囊密封圈形状与人体面部形状配合基本上可以达到，但申请人在日后的生产过程中发现由于上述的橡胶气囊密封垫圈为不规则的形状，要加工成与人体面腔轮廓相接触吻合比较困难，想要控制每一个小部位不同的壁厚度更加困难，生产的工艺复杂且成品率低、加工速度较慢，无法投入批量生产，同时这种橡胶气囊密封垫圈佩戴时密封性能也没有达到想象中的程度。
发明内容
本发明的目的在于提供一种防毒面具和防颗粒物呼吸器及其制造方法，本申请提供一种重量轻、形状灵巧、两种防护功能的防毒面具过滤件，过滤件为从过滤件的两面吸进空气、双方向过滤吸附吸进空气中的各种有毒气体的防毒面具过滤件，一个整体过滤件同时具有防护有毒气体和高效防护微小颗粒物的两种功能，实现防毒面具和防颗粒物呼吸器两种功能合为一个整体产品，本申请采用活性炭纤维作为过滤吸附防护各种有毒气体，因对不同种类有毒气体活性炭纤维的吸附容量比活性炭颗粒的吸附容量大几倍、甚至大几十倍，活性炭纤维比活性炭颗粒的吸气阻力少很多，如设定吸附同样质量的有毒气体，那一个过滤件所需要的活性炭纤维的质量比过滤盒所需的活性炭颗粒的质量少用几倍，本申请发明创造采用过滤件作为过滤吸附各种有毒气体，去除了过滤盒外壳的自身重量，采用活性炭纤维的整体过滤件重量比活性炭颗粒的整体过滤盒重量轻很多，对使用者长时间佩戴不会感觉到下坠的不舒适感；本申请的过滤件吸进气体面积比传统的过滤盒吸进气体面积大几倍，过滤件吸进气体面 积是从整个过滤件的两面、双方向都可以同时吸进空气，因吸进气体面积很大，那该过滤件设放高效过滤棉的吸气阻力就不会大了，本申请发明创造采用焊接工艺将多层过滤吸附材料叠放组合加工成防毒面具过滤件代替传统的防毒面具过滤盒功能使用，改变了目前特种劳动防护用品的防毒面具的功能单一，只能防护各种有毒气体的单种功能，不能同时高效防护微小颗粒物功能的现状，又改变了传统的质量笨重的只能从过滤盒口一面、单方向吸进空气的防毒面具过滤盒；本申请发明创造采用中空环形充气式的弹性体气囊密封气垫作为防毒面具的密封垫圈，弹性体气囊密封气垫是可变形的密封垫圈，弹性体气囊密封气垫件为敞开式内壁设有芯模组合的模具工艺生产，可以如意控制弹性弹性体气囊密封气垫与人体面部相接触面每一个小部位壁的不同厚度，鼻梁处还能立刻变薄比同一平面其他部位能薄39％的厚度，在同一平面位置模具的鼻梁处壁厚度可以控制得特别薄，其他部位壁厚度可以立即加厚，采用中空环形充气式的密封垫圈，有些部位很薄也不会使整个密封垫圈变形，克服弹性体气囊密封气垫加工工艺复杂、成品率低、加工速度较慢的难题；弹性体气囊密封气垫减少了防毒面具死腔体积，充气式的弹性体气囊密封气垫内部有流动的气压，对人体面部每一个部位的压迫力度不同，可以任意填补各种不同脸型凸出和凹进的部位，更加符合各种形状的人体面部轮廓，使用者根据脸形不同，可以充加或减少弹性体气囊密封气垫内的气体，脸形小、鼻梁窄的再充加一点气体，脸形大、鼻梁粗(高)的再减少一点气体，由于弹性体气囊密封气垫与面部接触面部位可以做得较柔软，对各种不同脸型凸出部位都没有压迫感，把弹性体气囊密封气垫与人体面部接触面部位的形状设计成人体面腔轮廓相接触吻合，在弹性体气囊密封气垫内侧与人体面部下巴接触的部位设有防滑片，更加适合使用者的各种不同脸形，又能起到防止面具下滑时导致密封性能受到影响，本申请发明创造的防毒面具的密封垫圈，能达到最佳的密封性能和舒适性，长期佩戴不会感觉到对脸部有些部位有压迫性的难受反感。
