为了使本揭示内容的叙述更加详尽与完备，下文针对本发明的实施方式与具体实施例提出了说明性的描述；但这并非实施或运用本发明具体实施例的唯一形式。实施方式中涵盖了多个具体实施例的特征以及用以建构与操作这些具体实施例的方法步骤与其顺序。然而，亦可利用其它具体实施例来达成相同或均等的功能与步骤顺序。
本发明实施例提供了一种流动水杀菌装置，请参阅图1、图2和图3所示，该流动水杀菌装置包括：从下至上依次连通的第一流体腔10、连接腔30和第二流体腔20，第一流体腔10的侧壁上和第二流体腔20的侧壁上均设有第一紫外辐射组件41、第二紫外辐射组件42或第三紫外辐射组件43中的至少一种。
其中，请参阅图4至图6所示，第一紫外辐射组件41包括用于对流体进行紫外光照射的辐射元件1和用于对紫外光进行反射的抛物面反射镜2；第二紫外辐射组件42包括用于对流体进行紫外光照射的辐射元件1和用于对紫外光进行聚合的凸面透镜3；第三紫外辐射组件43包括用于对流体进行紫外光照射的辐射元件1、设于辐射元件1一侧的用于对紫外光进行聚合的凸面透镜3、以及设于辐射元件1另一侧的用于对紫外光进行反射的抛物面反射镜2。在第一紫外辐射组件41，辐射元件1位于抛物面反射镜2的焦点处，相对于单独设置辐射元件1，第一紫外辐射组件41发出的紫外光更均匀更分散。在第二紫外辐射组件42中，辐射元件1位于凸面透镜3的焦点处，用于将辐射元件1发出的分散的光聚合成平行光，第二紫外辐射组件42发出的紫外光更均匀。在第三紫外辐射组件43中，辐射元件1位于凸面透镜3的焦点处，同时也位于抛物面反射镜2的焦点处，凸面透镜3用于将辐射元件1发出的分散的光聚合成平行光，发出的紫外光更均匀更分散，抛物面反射镜2用于将接收的从流体腔内射入的紫外光进行反射，再被凸面透镜3聚合后重新发送至流体腔内，增加紫外光效率。
进一步地，第一流体腔10和第二流体腔20的侧壁上还设有锯齿形反射组 件44，更进一步地，第二紫外辐射组件42和锯齿形反射组件44分别在两侧的侧壁上相对设置，或者，锯齿形反射组件44和第三紫外辐射组件43分别在两侧的侧壁上相对设置，如图1、图2和图3所示。锯齿形反射组件44用来反射紫外光偏转方向，不至于使得紫外光原路返回，对辐射元件产生不利影响；锯齿形反射组件44是采用光栅形式，增加光的集中度。
在一个优选实施方式中，如图1、图2和图3所示，第一流体腔10和第二流体腔20相对于连接腔30呈镜像对称。在本说明书中，第二流体腔20的具体结构参见对第一流体腔10的说明。
在图1所示的实施例中，第一流体腔10底部设有第一流体入口10a，第二流体腔20顶部设有第一流体出口20a。
在图1所示的实施例中，连接腔30内设有由两个第一紫外辐射组件41组成的第一杀菌301，第一杀菌单元301中的两个第一紫外辐射组件41的紫外出光面分别朝向第一流体腔10和第二流体腔20，第一杀菌单元301和连接腔30的侧壁之间形成用于连通第一流体腔10和第二流体腔20的流体通道303。
在一个优选实施方式中，如图1所示，第一流体腔10从下至上依次包括倒置圆台段101、第一圆柱段102、第一圆台段103、第二圆柱段104和第二圆台段105。在本说明书中，“圆台”表示下底面直径大于上底面直径的正置圆台，“倒置圆台”表示下底面直径小于上底面直径的圆台。也就是说，第一圆台段103和第二圆台段105均为下底面直径大于上底面直径的正置圆台。第一流体腔10从下至上尺寸先增加再逐渐减小。第一流体腔10远离连接腔30的一端直径较大，第一流体腔10靠近连接腔的一端直径较小。其中，倒置圆台段101侧壁与竖直方向的角度为a，第一圆台段103侧壁与竖直方向的角度为b，第二圆台段105侧壁与竖直方向的角度为c。这种台阶状设计，可以有效稳定水流，尤其是在倒置圆台段101、第一圆台段103和第二圆台段105内设置的第一紫外辐射组件41，对水流影响更甚，可以造成不同程度的回旋和湍流，将水中细菌和粒子带动运动，增加光照射接触面，a、b、c的角度用来调节光照区域和流水样态，是具有相当作用的参数。
在以上实施方式的基础上，请参阅图1所示，倒置圆台段101的侧壁上设有第一紫外辐射组件41，第一圆柱段102的侧壁上设有交错排列的第三紫外辐射组件43和锯齿形反射组件44，第一圆台段103设有第一紫外辐射组件41，第二圆柱段104的侧壁上设有交错排列的第三紫外辐射组件43和锯齿形反射组件44，第二圆台段105设有第一紫外辐射组件41。在第一圆柱段102内，第三紫外辐射组件43和锯齿形反射组件44在侧壁上交错排列，锯齿形反射组件44和第三紫外辐射组件43分别在两侧的侧壁上相对设置；第二圆柱段104内，第三紫外辐射组件43和锯齿形反射组件44在侧壁上交错排列，锯齿形反射组件44和第三紫外辐射组件43分别在两侧的侧壁上相对设置。第一紫外辐射组件41分别设于倒置圆台段101、第一圆台段103和第二圆台段105的侧壁上，倒置圆台段101的角度a使位于其上的第一紫外辐射组件41的辐射元件通过反射光照射到第一流体腔10的中间通道以及第一圆台段103剩下的盲区，解决整个区域无光照射的问题。
在以上实施方式的基础上，请参阅图2所示，倒置圆台段101的侧壁上设有第一紫外辐射组件41，第一圆柱段102的侧壁上设有交错排列的第二紫外辐射组件42和锯齿形反射组件44，第一圆台段103设有第一紫外辐射组件41，第二圆柱段104的侧壁上设有交错排列的第二紫外辐射组件42和锯齿形反射组件44，第二圆台段105设有第一紫外辐射组件41。在第一圆柱段102内，第二紫外辐射组件42和锯齿形反射组件44在侧壁上交错排列，锯齿形反射组件44和第二紫外辐射组件42分别在两侧的侧壁上相对设置；第二圆柱段104内，第二紫外辐射组件42和锯齿形反射组件44在侧壁上交错排列，锯齿形反射组件44和第二紫外辐射组件42分别在两侧的侧壁上相对设置。第一紫外辐射组件41分别设于倒置圆台段101、第一圆台段103和第二圆台段105的侧壁上，倒置圆台段101的角度a使位于其上的第一紫外辐射组件41的辐射元件通过反射光照射到第一流体腔10的中间通道以及第一圆台段103剩下的盲区，解决整个区域无光照射的问题。
在一个优选实施方式中，请参阅图2所示，该流动水杀菌装置还包括从所 述第一流体腔10底部伸入所述第一流体腔内的第一中心管50，第一中心管50具有一纵向延伸的内部流体通道501，第一中心管50靠近连接腔30设置的一端开设有第一出水口502。流体在流经第一中心管50时接受第一次照射，离开第一中心管50后进入第一流体腔10其它部分后再接受一次照射，延长照射时间。
请参阅图3所示的优选实施例中，图3所示的实施例在图2所示实施例的基础上，该流动水杀菌装置还包括：从第二流体腔20顶部伸入第二流体腔20内的第二中心管60，第二中心管60具有一纵向延伸的内部流体通道601，第二中心管60靠近连接腔30设置的一端开设有第二出水口602。该流动水杀菌装置还包括：第一管道70和第二流体出口20b，其中，第一管道70一端设于第一流体腔10侧壁中部、另一端设于第二中心管60顶端，第一管道70连通第一流体腔10和第二中心管60；第二流体出口20b开设于第二流体腔20侧壁中部。
图3所示的实施例中，连接腔30内卡设有第二杀菌单元302，第二杀菌单元302包括两个第一紫外辐射组件41，第二杀菌单元302中的两个第一紫外辐射组件41的紫外出光面分别朝向第一流体腔10和第二流体腔20，在图3所示实施例中，连接腔30内无过水通道。流体从第一中心管50的内部流体通道501进入后，从第一出水口502流出第一中心管50进入第一流体腔10内，再依次进入第一管道70和第二中心管60，从第二出水口602流出进入第二流体腔20，最后从第二流体出口20b流出，进一步增加了流体在流动水杀菌装置中的停留时间。
图3所示的流动水杀菌装置除了可以垂直使用，还可以平躺使用，如图7所示。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
