等离子纳米催化消毒净化器
技术领域
本发明涉及环保类的家用电器产品， 具体的说是一种脉冲高压等离子体， 负离子 发射器和纳米催化技术结合为一体的等离子纳米催化消毒净化器。 背景技术
环保产品中空气净化器现在越来越受到人们的青睐， 因此其市场潜力是极大的。 目前空气净化器中有， 负离子空气清析器、 臭氧空气净化器， 紫外空气净化器、 光催 化空气净化器和等离子体空气净化器， 以及各种类型相结合在一起的净化器组合的产 品。 从以上的空气净化器品种来分析， 用工作效率和功能进行比较， 臭氧和光催化组 合的空气净化器为娇娇者。 但仍存在结构复杂， 功效低等不足。
本发明人曾参与研制了以下项目： 车用消毒杀菌净化器： 专利号： 96217032.2; 室用消毒杀菌净化器：专利号： 96217998.1；臭氧光催化空气净化器：专利号： 9821668.2: 高效臭氧水质净化器： 专利号： JL99209701.C等等， 这些专利与现有市场上推出的此 类产品均为小功率的等离子和负离子的技术应用。
从包括中国专利在内的有关资料检索表明， 目前尚未具有高灭菌净化能力， 杀菌 速度快的等离子与纳米催化技术结合的产品。 发明内容
为了克服现有等离子体产品中存在功率小， 以及结构复杂、 灭菌能力差等缺点， 本发明提出了一种等离子纳米催化消毒净化器。
本发明解决其技术问题所采用的技术方案是： 一种等离子纳米催化消毒净化器， 其特征是： 包括机体外壳， 机体外壳的上方幵设有定向导风板， 机体内在定向导风板 的相应位置上安装有活动导风板； 机体内活动导向板的下端安装有等离子反应器， 所 述的等离子反应器内从上到下顺序安装有负离子正极片、 负离子负极片、 等离子正极 片、 等离子负极片； 所述的负离子正极片、 负离子负极片、 等离子正极片、 等离子正 极片为网状的不锈钢片， 网状的不锈钢片表面附着有纳米制备技术制备的纳米催化剂 薄层； 所述的等离子正负极片由 2~30组构成； 所述的纳米材料为铜、钛和铂三元催化 剂； 等离子反应器的下端设置有电功能控制器， 电功能控制器的下端为风机箱和风机 箱内的风机； 所述的电功能控制器内设有负离子电路和等离子电路； 机体内的下端设 有电源开关； 外壳的正面在定向导风板的下端为机壳面板； 面板的正上方设置有功能 显示器， 面板的正下方内设置有过滤网； 这些零部件结合构成了本发明的等离子纳米 催化消毒净化器。
所述的电功能控制器内的负离子和等离子的电路由：
电源电路： 本机采用 220V电源电路， 通过 F,、 F2两个保险管分两路工作； 一路 为风机电源， 风机的调速和遥控电路为常用的电扇遥控电路， 大功率等离子和负离子 发射电路： 8!为电源变压器， D D4为桥式整流电路， 为滤波电器， 为泄放电阻， R2为降压电阻， 220V高压电经过变压器变压， 整流滤波降压， 输入 I 三端稳压器稳 压， 作 IC2和 IC3的电流电压 VCC输入；
脉冲振荡电路： 由 IC2中三个与非门和 R3、 、 W2、 C3组成的电路， 振荡 电路的波形为脉冲波， 它的脉宽由小 来调节它的频率曲 W2来调节， 振荡输出的脉 冲波经过第四个与非门整形后激发 6非门电路；
脉冲缓冲分配电路： 6非门中每三个非门组成一路， 脉冲缓冲级使输出的电流加 大， 当大功率管负载变化时不会影响脉冲振荡电路的频率和电压；
讯号输入与保护电路， W3、 W4为脉冲讯号幅值大小的调节电位器， C4、 C5为隔 直电容器， D7、 ^为大功率管的输入保护电路；

本发明的净化器经组装后， 放在拟定的空间就可以对室内空气进行消毒、 杀菌、 除臭等净化了。
本发明的有益效果是： 本发明可以广泛用于医院会议室、 办公室、 食品业、 计算 机房公共场所及家庭等场合。 对细菌、 病毒进行杀灭， 防止交叉感染， 其对微生物阻 留率可达 95%以上 （2小时）。 和本发明同效能的空气洁净设备之一， 层流罩装置价格 比本机要高好几倍， 它净化微生物气溶胶粒子只在 0.1 μ ηι~5 μ ιη之间， 小于 0.1 μ ηι 时， 它的 "高效过滤器"（内部装置之一）就失效了， 且其滤材对空气的阻力很大， 影 响设备的净化效率， 并且滤材需定时更换， 我们知道， 微生物气溶胶粒子大约在
0.002〜30ym之间， 细菌的粒子约在 0.25~20 μ m， 病毒粒子约在 0.002~30 μ m之间， 所以层流罩对细菌有很好的过滤能力， 面对病毒却没有能力过滤， 本发明最小可以收 集到 0.01~0.001 μ πι级超细尘粒， 对病毒杀灭的功能远比层流罩强。 本发明同时还具 备净化各种有机物、 氨等有毒气体的功能。 如在 22.5米 3空间内注入各类有毒气体， 平衡后各气体浓度为甲醛 4.14mg/m3,苯 9.37 mg/m\ 甲苯 8.09 mg/m\ 二甲苯 5.04 mg/m3、 氨 6.65 mg/m3,经 180分钟净化后， 各气体净化率为： 甲醛 76.6%、 苯 87.8%、 甲苯 91.8%、 二甲苯 93.6%、 氨 92.9%。 因此， 本发明能够达到拟定的目的。 附图说明
