本申请的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本申请中的具体含义。
参照图1至图3，本申请实施例的消毒杀菌电梯空气净化装置，包括有送风顶板1、净化机构2和导风管，其中，送风顶板1设于电梯轿厢内，与电梯轿厢的顶面内壁之间形成送风夹层，净化机构2包括固定于电梯轿厢的侧内壁上的壳体21、配置在壳体21内的消毒灭菌模块、过滤结构22和导流风机23，壳体21上设有进风口及出风口，导风管的一端伸入至送风夹层内且另一端与出风口接通。
更为具体地，送风顶板1上设置多个通风孔11，各通风孔均自送风顶板1 的上表面贯穿至下表面，为了提高通风孔的排布美观度，也提高通风孔在送风顶板1上的分布均匀性，各通风孔在送风顶板1上以矩阵的形式排布；过滤结构22则覆盖在进风口处，进风口与出风口之间连接一风道24，消毒灭菌模块和导流风机23均置于风道24内。
根据本申请实施例的消毒杀菌电梯空气净化装置，其包括有送风顶板1、净化机构2及导风管，送风顶板1与电梯轿厢的顶面内壁之间形成送风夹层，送风顶板1上还设置多个通风孔，被净化机构2净化后的空气自导风管进入送风夹层，空气在送风夹层内与电梯新风汇合，再经过通风孔以层流态流入至电梯轿厢，实现被送入空气的分散和均匀，实现净化气流的全区域覆盖，满足电梯轿厢内乘客的正常呼吸需求，提高使用体验。
在本申请的一些实施例中，风道24内设置有导风罩，导风罩位于风道24的进风端，导流风机23位于导风罩内。进一步地，该具体实施例中，导风罩的横截面面积小于风道24的进风端的横截面面积，如此设置，以导风罩为界，风道24被划分为并列的加速区和均速区，导流罩所围区域为加速区，导流罩外的区域为匀速区；导流风机23为加速区内的空气流动速度提供加速的动力支持。由于空气经过过滤结构22后，风量将相应地减少，导风罩和导流风机23的配合设置能够使风量减少的部分得到补偿。更为具体地，为了提高导流风机23的安装牢固性，减小因振动所导致的噪声的产生，导流风机23安装在一固定架上，固定架通过紧固件与导风罩连接，需要说明的是，所采用的紧固件为螺栓或者螺钉。与此同时，该具体实施例中的导流风机23为涡轮离心风机。
在本申请的具体实施例中，壳体21包括后罩壳211及拼装在后罩壳211上的前盖，进风口设置在前盖上，且出风口设置在后罩壳211上。进一步地，进风口通过多个贯穿前盖相对表面的穿孔形成，如此能提高进风的均匀性和分散 性。
更为具体地，过滤结构22为板状的高效过滤器，该高效过滤器对进风口实现全覆盖。高效过滤器能够过滤尘埃粒子(病毒细菌等颗粒物)，其对于粒径大于等于0.5μm的微粒的计数效率在95％至99.9％之间，过滤效果好。再者，本实施例当中，消毒灭菌模块包括至少一支紫外线杀菌灯25及若干个等离子发生器26。空气从进风口进入壳体21时，流经过滤结构22将颗粒物排除在壳体21外，进入的空气不仅能被紫外线杀菌灯25的照射，消灭浮游在空气中的细菌和病毒等，还能融合通过等离子发生器26所释放负离子，空气的清新度得以提高，得到彻底的净化消毒。
在本申请的一些实施例中，导风管设置在电梯轿厢的外侧，以减小该消毒杀菌电梯空气净化装置所占用的电梯轿厢的内部空间，提高电梯轿厢内的整体环境整洁度和美观度。
当然，本申请的设计创造并不局限于上述实施方式，熟悉本领域的技术人员在不违背本申请精神的前提下还可作出等同变形或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
