Description

一种过流式杀菌装置及其壳体
本发明属于净化设备领域，尤其涉及一种过流式杀菌装置及其壳体。
随着人们生活水平的提高，人们对饮用水质量的要求也越来越高。目前的水消毒产品市场大量引进了紫外LED灭菌的方式，对于流动水而言，杀菌方式一般是通过在水管中设置紫外LED，利用紫外LED产生的紫外线对水管中的流动水进行照射，从而实现杀菌消毒的作用。
过流式杀菌装置灭杀细菌需要紫外线的辐射强度达到一定的阀值。市面上常规的杀菌装置通常采用圆柱形反射内腔，光线在内壁上反射后会产生聚焦效应，导致辐射能量在横截面上分布不均匀。流动水在通过杀菌装置的过程中，部分细菌通过的路径未流经高能量区域，影响了杀菌率。
发明内容
本发明所要解决的技术问题在于提供一种过流式杀菌装置及其壳体，旨在解决现有技术中的过流式杀菌装置，由于圆柱形反射内腔辐射不均匀，从而影响杀菌率的问题。
为解决上述技术问题，本发明是这样实现的，一种过流式杀菌装置的壳体，所述壳体内具有反光内腔，所述反光内腔的一端具有开口；所述反光内腔的横截面呈多边形，所述壳体的壁体上具有进水口和出水口，所述进水口和出水口分别与所述反光内腔相连通。
进一步地，所述反光内腔的横截面呈正多边形。
进一步地，所述反光内腔的横截面呈正方形。
进一步地，所述壳体由金属材料制成。
进一步地，所述壳体由若干块金属片围设而成。
本发明还提供了一种过流式杀菌装置，包括所述的壳体、光源以及聚光系统，所述光源为紫外线光源，所述光源可拆卸地连接在所述壳体上靠近所述反光内腔开口的一端，且所述光源朝向所述反光内腔的开口，所述聚光系统设置在所述光源与所述反光内腔的开口之间。
进一步地，所述光源包括若干个200～320nm波段的紫外LED芯片以及电源，所述若干个LED芯片分别与所述电源电连接。
进一步地，所述光源还包括用于散热的散热装置。
进一步地，所述聚光系统包括一组或多组透镜。
进一步地，所述光源与所述壳体螺纹连接。
本发明与现有技术相比，有益效果在于：本发明的一种过流式杀菌装置及其壳体，其壳体具有反光内腔，且所述反光内腔的横截面呈多边形，即相当于所述反光内腔为多面柱体形状。紫外光线通过多面柱体的反光内腔后，会产生积分效应，使光线在经过短距离混光后，能够均匀地覆盖整个横截面，从而克服了常规的圆柱形腔体光线覆盖不均匀的缺点，提高杀菌率。

所述聚光系统3包括一组或多组透镜31，所述透镜31装配在所述LED芯片21的外侧，用于将LED芯片21发出的大角度光线汇聚为一个较小发散角的集中光线，从而能够有效的杀菌消毒。
在本发明实施例中，所述壳体1的外缘上还包裹有一个塑胶材质的外壳4，通过所述外壳4对所述壳体1进行保护，从而使得所述壳体1能够采用薄金属片围设而成，使得生产过程中的金属耗材大大减少，从而降低了生产成本。同时，薄金属片为批量生产的卷材，金属片的表面光洁，反射率高，能够提高杀菌效率。
综上所述，本发明实施例提供的一种过流式杀菌装置100及其壳体1，其通过将壳体1的反光内腔11做成多面柱体的形状，使得紫外光线通过多面柱体的反光内腔11后，会产生积分效应，进而使得光线在经过短距离混光后，能够均匀地覆盖整个横截面，从而克服了常规的圆柱形腔体光线覆盖不均匀的缺点，提高杀菌率。
