使用时，流体经进液口流入灭菌腔，由于隔板104的阻挡，流体流入灭菌模块与灭菌腔的底部腔壁之间和/或灭菌模块之间的间隙(当安装有多个灭菌模块时，灭菌模块之间以及灭菌模块与灭菌腔的底部腔壁之间均可以具有间隙)，绕灭菌模块流经间隙之后，进入灭菌腔的另一部分，此过程中，流体绕灭菌模块流动，可以利用流体带走灭菌灯产生的热量，为灭菌灯降温，同时灭菌灯发出紫外线，对流体进行灭菌消毒，然后流体从出液口106流出。
优选地，所述流体灭菌装置还包括设置于所述出液口下方的挡板，如图2所示的挡板109。挡板109的设置可以阻挡流体迅速流向出液口，从而更多地流经灭菌模块的表面，带走灭菌模块的灭菌灯产生的热量，提升散热性能，另外也可以延长流体流经灭菌腔的时间，提升灭菌效果。更进一步地，所述挡板可以为透明的，从而可以不阻碍灭菌灯发出的紫外光对流体的灭菌杀毒作用。相似地，隔板104也可以是透明的。
优选地，所述安装底座上还设置有散热部件，如图2所示，在安装底座下方还可以设置有散热部件110，散热部件110可以与装置的外壳接触，从而 辅助更好地对灭菌模块进行散热。
安装底座可以提供电连接接口，例如，可以通过安装底座与外接电源线111相连。
优选地，所述流体灭菌装置包括一个灭菌模块，此时，如图2所示，灭菌模块与灭菌腔的底部腔壁之间具有环形间隙，流体流经该环形间隙，带走灭菌模块的热量，为其降温。
图3和4示出了本申请优选的第二实施方案的流体灭菌装置的外观图和剖视图。如图4所示，一种流体灭菌装置可以包括灭菌腔201、位于所述流体灭菌装置底部的一个或多个灭菌模块202、安装所述灭菌模块的安装底座203以及隔板204，所述流体灭菌装置顶部设置有进液口205和出液口206；所述隔板设置于所述进液口和出液口之间并与所述一个或多个灭菌模块的表面接触，隔板将所述灭菌腔分成两个部分，在所述隔板靠近灭菌模块处设置多个透水孔；所述灭菌模块与所述灭菌腔的底部腔壁之间和/或所述灭菌模块之间具有间隙，流体绕所述灭菌模块流经所述间隙；所述灭菌模块包括灭菌灯107和覆盖所述灭菌灯的透光板108，所述安装底座提供电连接接口。该实施方案的流体灭菌装置尤其适合用于约0.8L/M的流量的杀菌。
使用时，流体经进液口流入灭菌腔，由于隔板204的阻挡以及隔板204靠近灭菌模块的透水孔的设置，流体部分可以流入灭菌模块与灭菌腔的底部腔壁之间和/或灭菌模块之间的间隙(当安装有多个灭菌模块时，灭菌模块之间以及灭菌模块与灭菌腔的底部腔壁之间均可以具有间隙)，绕灭菌模块流经间隙之后，进入灭菌腔的另一部分，部分流体则通过隔板204的通孔流过灭菌模块的上表面进入灭菌腔的另一部分，此过程中，流体绕灭菌模块流动，可以利用流体带走灭菌灯产生的热量，为灭菌灯降温，同时灭菌灯发出紫外线，对流体进行灭菌消毒，然后流体从出液口206流出。
优选地，所述流体灭菌装置包括一个灭菌模块，此时，如图4所示，灭菌模块与灭菌腔的底部腔壁之间具有环形间隙。
图5和6示出了本申请优选的第三实施方案的流体灭菌装置的外观图和剖视图。如图6所示，一种流体灭菌装置，包括嵌套的内管和外管、位于所述外管底部的一个或多个灭菌模块302以及安装所述灭菌模块的安装底座303，所述外管与所述灭菌模块围成外腔304，所述内管与所述灭菌模块围成 内腔305，所述灭菌模块与所述外管的底部腔壁之间和/或所述灭菌模块之间具有间隙，流体绕所述灭菌模块流经所述间隙；所述流体灭菌装置两侧设置有进液口306和出液口307，所述进液口与外腔连通，所述出液口与内腔连通；所述灭菌模块包括灭菌灯308和覆盖所述灭菌灯的透光板309，所述安装底座提供电连接接口。
使用时，流体经进液口流入外腔，由于内管的阻挡，流体可以流入灭菌模块与外管的底部腔壁之间和/或灭菌模块之间的间隙，流体绕灭菌模块流经所述间隙(当安装有多个灭菌模块时，灭菌模块之间以及灭菌模块与外管的底部腔壁之间均可以具有间隙)，绕灭菌模块流经间隙之后，进入内腔；或者部分流体也可以经内管与灭菌模块之间的间隙流入内腔，此过程中，流体绕灭菌模块流动，可以利用流体带走灭菌灯产生的热量，为灭菌灯降温，同时灭菌灯发出紫外线，对流体进行灭菌消毒，然后流体从出液口307流出。
所述内管可以与灭菌模块接触或者与灭菌模块的表面之间有一定的间隙供流体通过。优选地，所述内管下方间隔地设置一个或多个挡块，所述挡块与所述灭菌模块的表面接触，通过这种方式，可以阻挡流体迅速地流入内腔，从而更多地绕灭菌模块的流动，带走灭菌模块的灭菌灯产生的热量，提升散热性能，另外也可以延长流体流经灭菌腔的时间，提升灭菌效果，同时也可以兼顾灭菌的效率，避免流体流速过慢。更进一步地，所述内管可以为透明的。从而可以不阻碍灭菌灯发出的紫外光对流体的灭菌杀毒作用。
优选地，所述流体灭菌装置包括一个灭菌模块，所述灭菌模块与所述所述外管的底部腔壁之间具有环形间隙，流体流经该环形间隙，带走灭菌模块的热量，为其降温。
优选地，所述安装底座上还设置有驱动电源，如图6所示，在安装底座下方还可以设置有驱动电源301，驱动电源可以用于供电，也可以通过电源线311与外部电源连接。
图7示出了本申请优选的第四实施方案的流体灭菌装置的示意图。如图7所示，一种流体灭菌装置，包括灭菌腔401、至少两个灭菌模块402以及一个或多个隔板403，所述流体灭菌装置设置有进液口404和出液口405，所述隔板设置于所述进液口和出液口之间并与所述灭菌模块间隔设置，所述灭菌模块与所述灭菌腔的腔壁和/或所述隔板的板壁之间具有间隙，流体绕所述灭菌 模块流经所述间隙。
使用时，流体经进液口404流入灭菌腔，由于多个隔板403的形成的流体路径，流体经灭菌模块与灭菌腔的腔壁和/或隔板的板壁之间的间隙，绕各个灭菌模块流动，此过程中，流体绕灭菌模块流动，可以利用流体带走灭菌灯产生的热量，为灭菌灯降温，同时灭菌灯发出紫外线，对流体进行灭菌消毒，然后流体从出液口流出。
此实施方案仅为示例性的实施方案，本领域技术人员可以理解，例如，在两个隔板之间，也可以设置多个灭菌模块，只要使得流体流经灭菌模块，带走灭菌灯产生的热量进行降温即可。
由于设置了多个灭菌模块，该实施方案的流体灭菌装置可以应用于15L/M的杀菌流量，而且可以达到99.99％的杀菌效果。
图8和9示出了本实施方案中所使用的灭菌模块的剖视图和结构分解图。使用时，此种灭菌模块可以旋入灭菌装置中，此时灭菌模块可以浸入流体中，使紫外灭菌灯在工作过程中产生的热量能够传导到流体中，实现快速散热，满足灭菌模块的散热需要。
如图8和图9所示，该灭菌模块10包括：固定盖1、透明镜片2、紫外发光源(紫外灭菌灯)5和底座6。其中，底座6具有第一容纳腔61，第一容纳腔61从底座6的第一端6a开口并向底座6第二端6b延伸；紫外发光源5设于第一容纳腔61中；透明镜片2设于第一容纳腔61开口处；固定盖1与底座6相配合将透明镜片2固定于第一容纳腔61开口处。
进一步地，透明镜片2由石英玻璃或其他透光材料制成，优选为石英玻璃，能够有效提高紫外光的输出，减少光损失，提高杀菌消毒效果。
进一步地，该灭菌模块10还包括设于所述底座6与所述透明镜片2之间的第一密封件3，底座6的第一端设有用于容纳第一密封件3的第一凹槽63。更进一步地，所述第一密封件3为密封圈，优选为防水O型圈，可实现固定盖1的密封，防止水进入灭菌模块10内部，影响紫外发光源5的正常工作。
进一步地，紫外发光源5通过一与第一容纳腔61内壁接触的导热件64设置于第一容纳腔61内。导热件64将紫外发光源5工作产生的热量快速传递给底座6，优选地，导热件64由导热胶制成。进一步地，为了增加导热件64与底座6的接触面积，导热件64可以无间隙的贴设于第一容纳腔61的底 壁和侧壁。
在一种优选实施方式中，底座6除第一容纳腔61的其他部分可以是实心的，灭菌模块10可以完全浸入流体中，依靠底座6进行散热。
在另一种优选实施方式中，参见图8和图9，底座6进一步具有第二容纳腔62；第二容纳腔62从底座6的第二端6b开口并向底座6第一端6a延伸，第二容纳腔62开口处设有具有多个散热孔71的底盖7。此时，灭菌模块10只能部分浸入水中，底座6的第二端6b不能浸入水中，第二容纳腔体62需要与外界连通进行散热，散热效果更佳。
进一步地，紫外发光源5包括：PCB板52和设于PCB板52上的多个LED紫外灯珠51，多个LED紫外灯珠51分散均匀排布，使杀菌面积更广，杀菌光照密度均匀。
进一步地，底座6被构造为圆柱体，底座6的第一端6a和第二端6b呈阶梯状分布，第二端6b内径较大，增加了底座6的外表面积。
具体地，固定盖1被构造为一内设有螺纹的中空腔，透明镜片2设于第一容纳腔61开口并与固定盖1一端的内边缘抵接，所述第一密封件3设于底座6与所述透明镜片2之间，且容置于所述底座6第一端的第一凹槽63，紫外发光源5发出紫外光透过所述透明镜片2出射进行杀菌消毒，第一容纳腔61外壁具有与所述固定盖1密封螺接的螺纹，将所述透明镜片2固定于所述第一容纳腔61开口。
进一步地，参见图8和图9，所述透明镜片2与所述紫外发光源5之间设有反光器4，用于集中紫外光，减少紫外光的损耗，增加紫外光的光照强度，从而提高杀菌效率。
更优选地，所述反光器4为反光杯、反光罩或其他反光器件，优选为反光杯。
进一步地，底盖7上设有多个第一安装孔72，底座6的第二端6b外表面上设有多个与第一安装孔72相对应的供第一紧固件(图中未示出)穿设的第一孔位(图中未示出)，可实现底盖7固定设于底座6的第二端上。
或者，所述底座6上可以形成有用于增加表面积的凸起部66和/或凹陷部65，通过增加散热的表面积，从而进一步提高散热效果。
以上所述仅为本发明的较佳实施方式而已，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。
