具有二氧化氯消毒器的光触媒杀菌消毒机 技术领域
本发明涉及一种空气消毒净化机,特别是一种具有二氧化氯消毒器的光触媒杀 菌消毒机。
背景技术
纳米级二氧化钛（Ti02 )是近年来新材料研究中最富有活力的研究领域， 这 种超微颗粒具有比表面积大、表面活性高和良好的光催化特性，它既具有金属又具 有非金属的特异性能。 大量的研究资料表明， 纳米 Ti02对于杀灭细菌病毒和消除 气味是有用的， 其抗菌防霉、 对臭味进行控制都是十分有效的。 因为光催化性强， 作为高效净化作用和抗菌、 防腐、 除味、优化环境的功能尤其突出。 采用低计量紫 外光照射纳米二氧化钛即产生所谓的光触媒效应，二者便会发生反应，生成活性极 强的氢氧自由基，迅速将有机毒物分解为二氧化碳和水。 经实验证明， 纳米二氧化 钛作为高效净化剂， 其主要的净化原理如下： 它一种是低温深度反应技术， 光催化 剂纳米粒子在一定波长的光线照射下受激生成电子一空穴对，空穴分解催化剂表面 吸附的水产生氢氧自由基， 电子使其周围的氧还原成活性离子氧，从而具备极强的' 氧化一还原作用，将光催化剂表面的各种污染物摧毁， 由此达到净化目的使空气新 鲜。
人们应用纳米 Ti02的光催化特性制作了各种光触媒空气净化机， 如申请号为 03238375.4的中国实用新型专利光触媒空气消毒杀菌机， 申请号为 03259495.X的 中国实用新型专利光触媒紫外线空气净化消毒机。这种空气净化机不需要使用消毒 剂， 使用成本低，但是它只是对进入机腔内的空气净化， 并不能完全杀灭空气中的 细菌和病毒， 无法替代传统喷洒消毒剂进行杀菌消毒。 .
二氧化氯（C102 )是近年来广泛用于医疗卫生行业的杀菌杀灭病毒的环保消 毒剂， 它是一种高效低毒消毒剂， 它可以杀灭一切微生物， 包括细菌繁殖体、 细菌 芽孢、 真菌、 分枝杆菌和病毒等， 而且用量少、 作用快、 持续药效时间长， 而且不 会产生致癌的二氯曱烷、 三氯曱烷等卤代烃化合物（THMS ) ， 被世界卫生组织 ( WHO )和世界粮农组织 （FAO ) 向全世界推荐为 AI级高效安全消毒剂， 是国 际上公认的氯系消毒剂最理想的更新换代产品。 二氧化氯可将硫化物（如 H2S等） 迅速氧化成硫酸根离子， 去除有才««产生的臭味， 将 CN -、 N02-、 NH3氧化降解成
无毒的 C02、 N2等物质。 可见， 二氧化氯不仅灭菌效果好， 作为一个强氧化剂， 它还具有抗霹、 除臭等多方面的功能， 可广泛用于对公共场所环境空气、 冰箱、 冷 库、 办公室、 宿舍、 车厢及空调通风***的空气消毒、 除臭， 也可用于病人家庭、 病房及病人物品的杀菌消毒。
目前使用二氧化氯对空气进行消毒的方法是用喷雾器或气溶胶喷雾器将配制 好的二氧化氯溶液变成雾状喷洒在待消毒空间，该方法可以将药液喷洒到待消毒空 间的任何地方， 包括被家具等物品挡住的角落等， 不会留下无法消毒的死角，但是 喷洒出的药液中含有酸式和碱式金属盐离子， 会对电器设备的金属件产生腐蚀。 发明内容
本发明所要解决的技术问题是提供一种具有二氧化氯消毒器的光触媒杀菌消 毒机，该杀菌消毒机可替代传统喷洒消毒剂对空气进行杀菌消毒，能达到卫生学灭 菌要求， 且在消毒时不会对消毒空间内的物品造成损伤， 不会留下消毒死角，使用 简单方便， 该机用于日常净化空气时不需使用消毒剂等耗材， 使用成本低。
本发明具有二氧化氯消毒器的光触媒杀菌消毒机， 包括：
机箱， 该机箱含有主体、前网罩以及带出风口的后盖， 前网罩安装于主体前下 部， 前网罩与主体之间为杀菌室， 杀菌室内的立墙上开设通风口，后盖安装在主体 的后上部， 后盖与主体之间为气流混合室；
光触媒蜂窝体，该光触媒蜂窝体安装于前网罩内，光触媒蜂窝体与前网罩之间 安装过滤网；
若干紫外线灯， 该紫外线灯安装在机箱的杀菌室内的立墙上；
第一风扇， 该第一风扇安装在机箱的气流混合室内； 以及，
二氧化氯消毒器，该二氧化氯消毒器位于后盖的下边，并与主体通过铰链连接； 工作时，进入所述杀菌室的气流被光触媒和紫外线杀菌，经通风口进入所述气 流混合室，再与二氧化氯消毒器产生的二氧化氯气体混合,从后盖上的出风口排出。
进一步上述二氧化氯消毒器包括外壳，外壳内设储液室，储液室的底面上安装 曝气头， 储液室的底面下设气泵， 气泵的出气口通过单向阀与所述曝气头连接。
进一步还可包括一个第二风扇，第二风扇安装在所述杀菌室内的立墙上的通风 口处， 以加快空气净化速度。
还可在杀菌室内表面均涂覆纳米二氧化钛涂层， 以达到更好的净化效果。 本发明具有以下有益效果：
与采用喷雾器喷洒二氧化氯溶液对空气消毒相比，本发明是将二氧化氯溶液中 的二氧化氯分子由水相状态转入气相状态进入空气中进行杀菌消毒，它只把二氧化
氯分子激喷逸出到空气中，而溶液中的其它酸式和碱式金属盐离子大部分留在了溶 液中不会与消毒空间内的物品接触，因此能够避免喷洒二氧化氯溶液带来的酸式和 碱式金属盐离子对电器设^属件的腐蚀，能有效地避免对消毒空间内的物品造成 损伤。
它可以将二氧化氯溶液中的二氧化氯分子迅速逸散到空气中并在规定的时间 内达到规定的消毒浓度， 所以完全能达到卫生学灭菌要求。 而且， 由于二氧化氯分 子可以逸散到所有角落中， 所以能彻底消毒， 不会留下无法消毒的死角。
它既可替代传统喷洒消毒剂对空气进行杀菌消毒， 又可用于日常净化空气，且 在曰常净化空气时不需使用消毒剂等耗材， 使用成本低。
本机使用简单方便， 而且成本低，只需按待消毒空间大小向储液室内装入规定 用量的二氧化氯溶液，接通电源设定好消毒时间即可自动进行消毒，是预防空气传 播性疾病如非典、 流感、 禽流感、肺结核、 病房手术室消毒的最经济最适用的消毒 净化设备， 可广泛应用于家庭、 医院、 办公室、 生产车间等公共场所， 以及列车、 飞机等交通工具的消毒。

具体实施方式
参照图 1-7, 本具有二氧化氯消毒器的光触媒杀菌消毒机包括：
机箱 1， 该机箱 1含有主体 11、 前网罩 12以及带出风口 131的后盖 13， 前网 罩 I2扣接于主体 11前下部，该前网罩 12也可采用磁吸方式安装于主体 11前下部， 前网罩 12与主体 11之间为杀菌室 113，杀菌室 113内的立墙 111上开设通风口 112， 后盖 13安装在主体 11的后上部， 后盖 13与主体 11之间为气流混合室 114;
光触媒蜂窝体 3 , 该光触媒蜂窝体 3安装于前网罩 12内， 光触媒蜂窝体 3与 前网罩 12之间安装过滤网 2;
若干紫外线灯 4， 本机中紫外线灯 4采用 UV LED , 它们安装在机箱 1的杀菌 室 113内的立墙 111上；
第一风扇 6， 该第一风扇 6安装在机箱 1的气流混合室 114内； 以及， 二氧化氯消毒器 7, 该二氧化氯消毒器 7位于后盖 13的下边， 并与主体 11通 过铰链 (由铰轴 73，和轴套 73构成）连接， 二氧化氯消毒器 7与主体 11之间设置 磁吸装置将二者锁合为一体， 用手向外拉二氧化氯消毒器 7 , 可使该二氧化氯消毒 器 7绕铰链的铰轴转动与主体 11分开、 以便于加入二氧化氯消毒药液；
工作时， 进入所述杀菌室 113的气流被光触媒和紫外线杀菌， 经通风口 112 进入所述气流混合室 114， 再与二氧化氯消毒器 7产生的二氧化氯气体混合， 从后 盖 13上的出风口 131排出。
根据***门的消毒常规，空气中的二氧化氯分子需要达到一定的浓度才具有 消毒效果， 然而二氧化氯分子从二氧化氯溶液中自然逸出的浓度和时间难于控制， 无法保证达到规定消毒浓度， 因而靠自然逸出会使其消毒作用大大降低，难以保证 消毒效果， 所以本发明采用了以下特殊结构的二氧化氯消毒器 7， 它包括外壳 71 , 外壳 71内设储液室 72，储液室 72的底面上安装曝气头 77，储液室 72的底面下设 气泵 74， 气泵 74的出气口通过单向阀 75与所述曝气头 77连接。 工作时， 气泵 74 产生压缩空气输给曝气条 77， 曝气条 77曝气， 使储液室 72内的二氧化氯溶液中 的二氧化氯分子迅速由水相状态转入气相状态， 迅速逸出到气流混合室 114。 单向 阀 75用于防止储液室 72内的溶液返流入气泵 74。
二氧化氯消毒器 7的外壳 71和储液室 72是注塑成型的一体构件， 储液室 72 的横截面呈元宝形状， 使得二氧化氯消毒器 7与机箱的主体 11吸合时二者之间有 空间供空气流过， 储液室 72内壁有指示内容物体积的刻度， 向外拉开二氧化氯消 毒器 7时可看到刻度， 方便用户使用时度量消毒液的用量。 储液室 72也可设计成 月牙形或其它形状。
曝气头 77采用长条形的微孔曝气头，下设三个接口，单向阀 75通过一个四通 管件 76连接到该微孔曝气头 77的三个接口。
为了加快空气净化消毒的速度， 在所述杀菌室 113内的立墙 111上的通风口 112处安装有第二风扇 5。
为了达到更好的净化效果， 在杀菌室 113内表面涂覆有纳米二氧化钛涂层 113，。 并可进一步在过滤网 2的表面均设置纳米二氧化钛层做成光触媒过滤网， 在 杀菌室 113内四个立墙上均设置若干紫外线灯， 更充分地照射过滤网 2、 光触媒蜂 窝体 3以及杀菌室 113内表面的纳米二氧化钛。
后盖 13上设内凹手柄 132 , 用户可通过内凹手柄 132搬运该杀菌消毒机。 主体 11上面设置电源开关 8、 用于控制二氧化氯消毒器 7工作时间的定时装 置 9、用于控制紫外线灯 4的工作时间的^时装置 10。本实施例中定时装置采用机 械式定时器，也可以采用由单片机实现的电子式定时装置。图 5中 115为电源插座， 用于和外部电源连接给本机供电。
进一步， 可以在前网罩 12的进风栅格内安装一个二氧化氯浓度传感器并将其 输出接至机器的控制中心 (如上述单片机)， 通过二氧化氯浓度传感器检测室内二氧 化氯浓度，然后与预设的浓度值比较， 当超过设定的上限浓度时使二氧化氯消毒器 7的曝气头 77停止曝气， 当室内二氧化氯浓度低于设定的下限浓度时， 使二氧化 氯消毒器 7的曝气头 77重新开始曝气， 形成一个反馈***， 由机器自动将空间的 二氧化氯浓度保持在设定的范围内，通过该自动控制方法，可以精确地控制空间的 二氧化氯浓度， 以达到更好的消毒效果。 浓度设定可通过机箱上的按键完成。 本具有二氧化氯消毒器的光触媒杀菌消毒机包括分子态空气消毒部分和光触 媒空气净化部分两个功能部 它们可以同时工作， 也可以单独工作。 具体说明如 下：
用本机消毒时， 打开电源开关 8，设定好定时装置 9， 气泵 74产生压缩空气使 曝气条 77曝气,使储液室 72内的二氧化氯溶液中的二氧化氯分子迅速由水相状态 转入气相状态， 经气流混合室 114从后盖 13上的出风口 131迅速逸出至密闭的待 消毒空间， 使得在规定时间内 （5-10分钟）达到杀菌浓度， 并持续所要求的密闭 消毒时间。由于二氧化氯分子扩散迅逸和无孔不入，完全达到高效的空气消毒效果。 根据待消毒空间的大小，调整二氧化氯溶液的浓度和溶液的量就完全可以达到卫生 学的灭菌要求。第一风扇 6用于将气化状态的二氧化氯分子加速逸散到待消毒的空 间。
用本机净化空气时， 打开电源开关 8，设定好定时装置 10, 第二风扇 5将空气 从前网罩 12吸入杀菌室 113 , 空气中的花粉、 尘埃等大的悬浮微粒被过滤网 2吸 附阻隔下来， 较小的微生物， 如细菌、 病毒在光触媒蜂窝体 3中被粘附， 同时杀菌 室 113内的 UV LED发射 365nm紫外线光照射光触媒蜂窝体 3和杀菌室 113内壁 的纳米二氧化钛层， 产生 OH基团可以杀灭细菌、 病毒并消除异味净化空气， 把 污浊的空气净化为高氧含量的新鲜空气， 经通风口 112进入所述气流混合室 114 后， 从后盖 13上的出风口 131排出。 完全能满足日常对室内空气的净化消毒。
用本机对空气净化消毒时，打开电源开关 8，设定好定时装置 9和 10， 净化和 消毒功能同时开启，进入所述杀菌室 113的空气经过滤网过滤、被光触媒和紫外线 杀菌后， 经通风口 112进入所述气流混合室 114， 再与二氧化氯消毒器 7产生的二 氧化氯气体混合， 从后盖 13上的出风口 131排出。
