为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施方案，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施方案仅用以解释本发明，并不用于限定本发明。
本发明一方面提供了一种流体灭菌模块，所述流体灭菌模块可以包括灭菌灯以及容纳所述灭菌灯的灯腔，所述灯腔包括安装板、连接件、透光板以及透光板检测单元，其中，所述灭菌灯安装在安装板上，所述透光板通过连接件与安装板相连并覆盖灭菌灯，所述透光板检测单元用于检测透光板的应力或形变。
本发明的流体灭菌模块，通过灭菌灯发出的紫外光，透过透光板对流体进行灭菌杀毒。为了保护昂贵的灭菌灯免受流体的污染和损害，将其固定在安装板上，并通过连接件将透光板与安装板连接，透光板覆盖灭菌灯，既可以保护灭菌灯，也不妨碍灭菌灯起灭菌作用。为了监测流体灭菌模块运行时的情况，尤其是透光板的形变情况，避免透光板破裂带来灭菌灯受损，本申请的灭菌模块通过包括透光板检测单元，对流体灭菌模块工作时透光板的应力或形变进行监测，从而可以例如配合流体灭菌装置，调整例如流体流量或者通过其他措施，调节透光板承受的压力，避免透光板的破裂，有助于维持灭菌模块的稳定运行。
本申请中，灭菌灯可以为紫外LED灭菌灯，紫外LED灭菌灯具有优异的杀菌消毒效果。
本申请的透光板可以由合适的透光材料制成，只要能透过灭菌灯发出的光线即可，优选由石英材料制成。即，透光板优选为石英板，石英板对紫外线具有良好的透过率，而且也具有一定的强度，可以承受一定程度的压力。
所述灯腔中还可以包括预警单元，所述预警单元接收所述透光板检测单元的检测结果，并进行预警。例如，当透光板检测单元监测到透光板的应力或形变已经达到极限，则可以将该检测结果传送至预警单元，预警单元根据接收到的检测结果，发出报警信息，进行预警，可以例如要求人工干预或者采取其他措施，从而可以避免在透光板承压已经达到极限的情况下，杀菌模块继续工作，透光板破裂并导致灭菌灯受损，或者乃至灭菌装置整体受到彻底损害，带来严重损失。
进一步地，所述灯腔中还可以包括湿度检测单元，所述湿度检测单元用于检测灯腔中的湿度。为了更好地判断透光板是否破裂，可以在灯腔中设置湿度检测单元，该湿度检测单元的位置没有特殊限制，只要可以检测灯腔中的湿度即可。该湿度检测单元可以根据透光板检测单元的检测结果启动(例如，当检测到透光板达到极限形变时启动)，或者也可以由例如预警单元启动。若湿度检测单元检测到湿度值超过预定值，则说明透光板破裂，从而可以向外部控制系统发出信号，外部控制系统则可以迅速进行干预，例如可以自动断开电源，关闭进出水口，避免灭菌灯受到进一步的损坏。
本申请中，所述透光板检测单元可以为应力检测组件，从而可以直接监测透光板上承受的应力。此时，该应力检测组件可以设置在任何合适的位置，例如，可以设置在透光板上。
所述透光板检测单元也可以安装在所述连接件与所述透光板的连接处。将透光板检测单元安装在连接件与透光板的连接处，可以更方便地监测透光板的形变。
进一步地，所述透光板检测单元可以包括信号发生器和信号检测器，所述信号发生器和信号检测器对称安装在所述连接件与所述透光板的连接处。将信号发生器和信号检测器对称安装在所述连接件与所述透光板的连接处，当透光板发生形变时，信号发生器发出信号会由于透光板的形变，在传递至信号检测器时，信号检测器检测到的信号会发生变化，从而可以根据信号检测器检测到的信号判断透光板的形变情况。更优选地，所述信号发生器和信号检测器可以安装在与所述透光板位于同一平面的位置处。
例如，所述信号发生器可以为射线发射器，所述信号检测器可以为射线接收器。射线发射器可以发出X射线，射线接收器可以接收该X射线并形成衍射峰；透光板的形变(应力变化)会带来衍射峰的位置变化。从而通过射线接收器所接收的X射线并观察形成 的衍射峰，即可判断透光板承受的应力以及由此带来的形变是否达到极限。
或者，所述信号发生器可以为激光发射器，所述信号检测器可以为光电二极管。如图1所示(为了清楚的目的，本图是夸张示意，真实情况下透光板不会有这么大的形变)，激光发射器111可以发出激光，在透光板没有达到弯曲极限时，激光可以到达光电二极管121，产生电子，形成高电平；而当透光板的形变达到极限时，激光不能到达光电二极管，没有产生电子，形成低电平。因此，通过高低电平的转换或者切换，就可以判断透光板是否处于极限位置。
进一步地，所述流体灭菌模块还包括压力调节装置，所述压力调节装置与所述灯腔连通，用于调节所述灯腔中的压力。通过压力调节装置的设置，例如当监测到透光板承受过大压力时，可以调节容纳灭菌灯的灯腔中的压力，使得流体灭菌模块工作时灯腔中的压力可以抵消掉部分或者全部的流体对灯腔透光板的冲击，从而避免透光板受流体的压力破裂，由此进一步可以降低透光板的厚度，提高灭菌灯发出的光的利用率，提升消毒灭菌效果，从而非常方便应用于大流量流体的灭菌消毒的处理。
进一步地，所述压力调节装置包括压力传感器、气体动力机和处理器，所述压力传感器检测透光板所承受的压力，所述处理器根据所述压力传感器的检测结果控制所述气体动力机向所述灯腔中通入或抽出气体。具体地，压力传感器可以检测透光板承受的压力，然后处理器根据压力传感器的检测结果以及透光板的固有的承压能力，可以控制气体动力机向灯腔中输入或者抽出气体，以调节灯腔中的压力，从而灯腔中的压力可以部分或者全部地抵消透光板受到的来自流体的冲击或压力，避免透光板受到冲击而破损。更具体地，可以使得透光板受到的流体的冲击，即流体压力与灯腔中的气压的差值，即压力传感器检测到的透光板所承受的压力(流体压力与灯腔中的气压的合力)小于或者等于透光板的承压能力。压力传感器可以实时检测透光板承受的压力的变化，处理器可以据此调节气体动力机的运行，保持流体灭菌模块的平稳运行。另外，通过向灯腔中通入低温的气体，例如，温度为0℃至20℃之间的气体，优选5℃至20℃之间的气体，还可以降低灭菌灯的温度，实现对灭菌灯的散热功能。另外，当所述透光板检测单元为应力检测组件时，应力检测组件也可以充当此处的压力传感器。
进一步地，该压力调节装置还可以包括气体循环装置，用于使气体循环运行。该气体循环装置使得通入灯腔中的气体循环运行，气体循环运行时，一方面可以更好地带走灭菌灯的热量，起到散热的作用，从而减少散热结构的使用，降低产品厚度和在一定程度上降低成本；另一方面也可以节约所使用的气体，进一步降低成本。
优选地，所述流体灭菌模块还可以包括散热器，且散热器用作所述安装板。为了提升所述灭菌模块的散热性能，所述流体灭菌模块还可以包括散热器，且可以利用散热器用作灭菌灯的安装板，方便将灭菌灯使用过程中产生的热量散发出去。具体而言，例如散热器可以和透光板通过连接件连接，由此构成灯腔，灭菌灯可以例如固定在散热器的下表面上，流体灭菌模块工作时，流体流经散热器的上表面，从而可以利用流体带走热量，进行散热。
更进一步地，散热器上还可以设置有散热鳍片。散热鳍片可以例如设置于散热器的上表面上，使得流体流动时会流经散热鳍片，可以更好地辅助散热器的散热，更充分地利用流体带走热量，辅助进行散热，从而极大地提高了散热效果。
图2示出了本申请一个优选实施方案的流体灭菌模块的剖视图。如图2所示，流体灭菌模块100包括散热器150作为灭菌灯160的安装板，透光板140通过连接件130与散热器150卡合连接，在连接件130上对称安装有信号发生器110和信号检测器120，散热器150上还安装有散热鳍片170。
本发明还提供了一种包括本申请的流体灭菌模块的流体灭菌装置，所述流体灭菌装置可以包括一个或多个流体灭菌模块，流体灭菌模块将所述流体灭菌装置分成两个或更多个腔室。更具体地，可以在位于最下层的底层腔室设置出液口，位于最上层的顶层腔室设置进液口。流体从上层进液口流入灭菌装置，经过多个腔室完成杀菌消毒后从下层出液口流出，从而非常方便应用于大流量流体的灭菌消毒的处理。
进一步地，所述流体灭菌模块还包括散热器，且散热器用作所述安装板，所述散热器上还设置有散热鳍片；流体流经所述散热鳍片；所述散热鳍片沿流体流动方向设置或者垂直于流体流动方向设置。灭菌模块中的散热器上表面可以构成除底层腔室外各腔室的底面，流体流动时流经散热器的上表面，从而可以利用流体带走热量，对灭菌灯进行良好的散热，避免灭菌灯由于大量的热量受到损坏。沿流体流动方向设置时，不会阻碍流体的流动，流体可以比较迅速地通过，沿垂直于流体流动的方向设置时，散热鳍片会阻碍流体的流动，降低流体流经腔室的速度，增长流体流经腔室的时间。从而，进一步地，所述散热鳍片中，位于顶层腔室中的散热鳍片可以沿流体流动方向设置，由此流体可以比较迅速地流经顶层腔室，提高整体的流速；位于其他腔室中的散热鳍片可以垂直于流体流动方向设置，从而可以降低流体流经其他腔室的速度，增长流体流经其他腔室的时间，取得更好的杀菌效果。
本发明的流体灭菌装置中的灭菌模块的数目可以根据灭菌效果的要求，结合装置设置的成本综合考虑。优选地，灭菌模块的数目可以为1至3个。
图3示出了本申请一个优选实施方案的流体灭菌装置的主视图。如图3所示，流体 灭菌装置1具有进液口11和出液口12。图4示出了该灭菌装置的剖视图。如图4所示，该灭菌装置中设置有一个图2所示的灭菌模块，该灭菌装置还包括上盖200和下盖300；其中，灭菌模块100将灭菌装置分成上下两个腔室，灭菌模块与上盖200构成上腔室，灭菌模块与下盖300构成下腔室。该流体灭菌装置工作时，流体经进液口从上腔室流入灭菌装置，然后流到下腔室中利用灭菌灯发出的紫外线进行灭菌后，从出液口流出。同时，透光板检测单元(即，信号发生器110和信号检测器120)可以持续监测透光板140承受的应力(发生的形变)的情况，当监测到透光板已经达到极限形变时，可以通知外部控制系统，或者在包含预警单元或者湿度监测单元的情况下，可以发出预警信息或者启动湿度监测。当例如湿度监测单元检测到湿度超过预定值时，则可以判断透光板发生破裂，从而可以通知外部系统进行干预，例如可以断开流体灭菌装置的电源，使得装置停止工作，并关闭进出水口，避免流体继续进入，对灭菌灯以及该流体灭菌装置造成更深度的破坏，同时避免未消毒的流体留出。
图5示出了本申请另一优选的实施方案的流体灭菌装置的剖视图。该灭菌装置中设置有两个灭菌模块(灭菌模块中透光板检测单元未示出)，将灭菌装置分成上中下三个腔室，上腔室13、中腔室14和下腔室15。杀菌模块包括散热器300，固定在散热器300上的灭菌灯，以及覆盖灭菌灯的透光板310，透光板密封灭菌灯，以保护灭菌灯免受流体的污染。散热器300还包括位于散热器上的散热鳍片320和330。如图3所示，可知流体经进液口从上腔室流入灭菌装置，然后流到中腔室直至下腔室，在中、下腔室中利用灭菌灯发出的紫外线进行灭菌后，从出液口流出。其中，位于上腔室13中的散热鳍片320沿流体流动方向设置，位于中腔室14中的散热鳍片330沿垂直流体流动方向设置。该优选的实施方案的流体灭菌装置可以实现每分钟60L水的消毒能力，且经测试，可以达到99.99％的灭菌效率。也可以说明，本申请的流体灭菌装置可以实现大流量流体的高效灭菌。
优选地，在一个或多个腔室底面可以设置有反光层。尤其是，可以在除顶层腔室之外的其他腔室底面设置反光层，反光层的设置，可以将灭菌灯发出的光线反射回流体中，提高光的利用率，从而提高杀菌消毒的效率。反光层例如可以为镜面铝。进一步地，为了避免反光层反射的光直射回灭菌灯造成灭菌灯的损坏，可以将反光层以一定的倾斜角度设置在各腔室的底面上。
优选地，在底层腔室中可以设置有流体挡块。流体挡块的设置可以降低流体流速，延长流体在腔室中流动的时间，以进行充分的杀菌消毒，同时还可以使流速稳定，延长走水路径，减少死水区。流体挡块的上述功能可以通过设置不同形状的功能实现。例如，更优选 地，所述流体挡块的高度与所述底层腔室的高度相同。与底层腔室的高度相同的流体挡块，可以使得流体不能漫过该流体挡块流动，而沿流体挡块形成的流体路径流动，从而可以更好地实现流体挡块的上述优点。对流体挡块的具体形状，没有特殊限制，只要可以实现挡块的功能即可。例如，可以为波浪形或者直线形。流体挡块可以沿各种方向设置，例如可以沿流体流动方向、垂直于流体流动方向或者与流体流动方向形成一定倾角设置。在这种情况下，所述底层腔室上的灭菌灯沿所述流体路径设置。即，将该底层腔室上的灭菌模块中的灭菌灯，均设置于流体路径的上方，而不设置于各流体挡块的上方，避免灭菌灯发出的紫外线被流体挡块挡住，损害消毒灭菌的效果。
进一步地，在所述流体挡块表面也设置有反光层。流体挡块上的反光层的设置也可以将灭菌灯发出的光线反射回流体中，提高光的利用率，进一步提高杀菌消毒的效率。优选地，在各流体挡块的侧面设置反光层。
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。
