进一步地，第二密封件50为楔形，第二密封件50优选为防水硅胶套。一方面防止水流泄露，另一方面防止内管301与主体30直接接触，进一步避免内管301管壁碰撞，造成损坏。

在上述实施例的基础上，本实施例中，参见图8和图9，杀菌模块10包括：固定盖101、透明镜片102、紫外发光源104和底座105。
其中，底座105具有第一容纳腔1051，第一容纳腔1051从底座105的第一端105a开口并向底座105第二端105b延伸；

更进一步地，第三密封件103为密封圈，优选为防水O型圈，可实现固定盖101的密封，防止水进入杀菌模块10内部，影响紫外发光源104的正常工作。
在上述实施方式的基础上，本实施例中，紫外发光源104通过一与第一容纳腔1051内壁接触的导热件1054设置于第一容纳腔1051内。导热件1054将紫外发光源104工作产生的热量快速传递给底座105，优选地，导热件1054由导热胶制成。进一步地，为了增加导热件1054与底座105的接触面积，导热件 1054可以无间隙的贴设于第一容纳腔1051的底壁和侧壁。
在第一个优选实施方式中，底座105除第一容纳腔1051的其他部分可以是实心的，杀菌模块10可以完全浸入流体中，依靠底座105进行散热，此种实施方式的优势在于使用方便，至少一个杀菌模块10可以直接放置于管道内或杀菌腔体内。
在第二个优选实施方式中，参见图8和图9，底座105进一步具有第二容纳腔1052；第二容纳腔1052从底座105的第二端105b开口并向底座105第一端105a延伸，第二容纳腔1052开口处设有具有多个散热孔的底盖106。本实施方式的杀菌模块10只能部分浸入水中，底座105的第二端105b不能浸入水中，第二容纳腔1052需要与外界连通进行散热，与第一个优选实施方式相比，本实施方式的杀菌模块10散热效果更佳。
在第三个优选实施方式中，请参见图10和图11所示，在第二种优选实施方式的基础上，第二容纳腔1052内设有第二散热件，进一步增加散热效果。

当杀菌模块10采用上述第二种或第三种或第四种优选实施方式时，杀菌模块10的底座105的第一端105a伸入至壳体20的容纳腔内，第二容纳腔1052需与外界连通散热，即为图4和图5采用的方式，图4和图5中为了增加散热效果，底座105最大限度的伸入壳体20容纳腔，只有底盖106在壳体20容纳腔外部。
进一步地，第二散热件包括：散热片组件108和设于散热片组件108上的散热风扇109。更进一步地，散热片组件108包括固定于第二容纳腔1052的散热板1081和多个从散热板1081边缘垂直延伸的散热片1082，散热风扇109设 于散热片1082上。紫外发光源104工作产生的热量通过散热板1081传递到散热片1082上，由散热风扇109加速散热片1082的热量从底盖106的散热孔中散失。
本实施例中的散热板1081、散热片1082和散热风扇9能够进一步提高散热效果，同时实现水冷和风冷并行散热，特别适用于底座105导热效果不好的情况。
在上述实施例的基础上，本实施例中，参见图8，底座105上形成有用于增加表面积的凸起部1065和/或凹陷部1066。本实施例中通过增加散热的表面积，从而进一步提高散热效果。
在上述实施例的基础上，本实施例中，透明镜片102与紫外发光源104之间设有反光器107，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。
进一步地，反光器107为反光杯、反光罩或其他反光器件，优选为反光杯。
进一步地，底座105被构造为圆柱体，底座105的第一端105a和第二端105b呈阶梯状分布，第二端105b内径较大，增加了底座105的外表面积。
具体地，固定盖101被构造为一内设有螺纹的中空腔，透明镜片102设于第一容纳腔1051开口并与固定盖101一端的内边缘抵接，第一密封件103设于底座105与透明镜片102之间，且容置于底座105第一端105a的第二凹槽1053，紫外发光源104发出紫外光透过透明镜片102出射进行杀菌消毒，第一容纳腔1051外壁具有与固定盖101密封螺接的螺纹，将透明镜片102固定于第一容纳腔1051开口。
本发明的杀菌模块10可以通过底座105将紫外发光源104在工作过程中产生的热量传导到水中，实现快速散热，满足大流量杀菌模块10的散热需要。
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。
