Description

一种智能负离子紫外快速杀菌装置 技术领域
本发明涉及一种智能负离子紫外快速杀菌装置,属于电子控制技术领域。
背景技术
由新型冠状病毒肺炎疫情想到,人类在不断地同自然界做斗争的同时,也时刻被自然界不同的致病微生物威胁着健康甚至生命。从疫情防护看由于当前人们对大自然缺乏敬畏,对危害人们健康的微生物(细菌、病毒等)缺少防护,当疫情袭来,细菌病毒泛滥,我们束手无策,殊不知传染病流行都离不开三个途径:传染源、传播途径、易感人群,缺一而不会致病,然而一个环节只要被我们隔断,人就安全了,不会发病。传染源和易感人群我们往往难以把控,需要提高全社会的健康意识和防范能力,同时需要全方位的提高身体素质,增强免疫力,切断传播途径往往是预防各种传染病最有效对对直接的方法。
目前广泛采用紫外线杀菌消毒,紫外线杀菌消毒是利用适当波长的紫外线能够破坏微生物机体细胞中的DNA(脱氧核糖核酸)或RNA(核糖核酸)的分子结构,造成生长性细胞死亡和(或)再生性细胞死亡,达到杀菌消毒的效果。紫外线消毒技术是基于现代防疫学、医学和光动力学的基础上,利用特殊设计的高效率、高强度和长寿命的UVC波段紫外光照射空气和物体表面能将各种细菌、病毒、寄生虫、水藻以及其他病原体直接杀死。
除了常用的紫外杀菌外,还可采用负离子进行杀菌,负离子具有较强的杀菌作用,其原理是负离子能使细菌或病毒蛋白结构发生改变(蛋白质两极性颠倒)或能量转移,从而使细菌病毒等微生物降低活性而死亡。负离子对人体没有任何副作用,以负离子技术作为核心的杀菌装置不但能够清新室内环境、消除细菌、病毒及有害微生物,对人体健康养生也有重要意义。
