Description

一种杀菌消毒装置和口罩
本申请要求于2020年07月24日提交国家知识产权局、申请号为202010725942.1、发明名称为“一种杀菌消毒装置和口罩”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及具有杀菌消毒功能的设备技术领域，尤其涉及一种杀菌消毒装置和口罩。
背景技术
波长为100nm～400nm的光统称为紫外光，这其中，波长为200nm～280nm的紫外光称为C波段紫外光(ultraviolet c，UVC)。UVC能量较高，能够用于消毒杀菌，且不产生其他化学污染物。借助此特点，UVC被广泛应用于净水器、空调器、消毒柜、医疗仪器、加湿器、饮水机、口罩等设备内，以对水、空气、餐具等待杀菌物进行杀菌消毒处理。在这些利用UVC进行杀菌的设备中，UVC在照射待杀菌物时，尤其是在照射空气、水等透光的待杀菌物时，不可避免地会有部分UVC未被待杀菌物所吸收，这些未被待杀菌物吸收的部分UVC最终被待杀菌物所处的腔体壁板所吸收，未得到充分利用，因此UVC的利用率较低，杀菌消毒效率较差。
发明内容
本申请的实施例提供一种杀菌消毒装置和口罩，能够提高杀菌消毒装置内紫外光的利用率和杀菌消毒效率。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，本申请一些实施例提供一种杀菌消毒装置，该杀菌消毒装置包括壳体和紫外光源；壳体内设有腔体，壳体上设有入口和出口，入口和出口均与腔体连通，壳体包括壳体本体和设置于该壳体本体的内表面的紫外光反射层，紫外光反射层用于反射紫外光；紫外光源用于向腔体内发出具有杀菌消毒作用的紫外光。
在将该杀菌消毒装置应用于具有杀菌消毒功能的设备中时，待杀菌物由入口进入腔体后，被紫外光源发出的紫外光照射，部分紫外光被待杀菌物吸收，以消灭待杀菌物中携带的病毒和细菌，未被待杀菌物吸收的部分紫外光照射至紫外光反射层上，并被该紫外光反射层反射，以使得未被吸收的部分紫外光再次经过待杀菌物，由此可以对待杀菌物进行第二次杀菌消毒处理，若在第二次杀菌消毒处理时，还存在未被待杀菌物吸收的部分紫外光，则该部分紫外光还能够被紫外光反射层再次反射，以对待杀菌物进行第三次杀菌消毒处理，由此依次对待杀菌物进行多次杀菌消毒处理，直至紫外光全部被待杀菌物吸收掉，从而能够提高紫外光的利用率。同时，紫外光的传播速度较快，无论是对静置于腔体的固体待杀菌物，还是对流经腔体的液体或者气体待杀菌物，均可进行多次杀菌消毒处理，因此杀菌消毒效率较高。
可选地，紫外光反射层由紫外光反射材料制作。
可选地，紫外光源为C波段紫外光发光二极管。
可选地，杀菌消毒装置还包括至少一个第一隔板，该至少一个第一隔板设置于腔体内，至少一个第一隔板将腔体分隔为多个彼此独立的腔体单元；入口的数量为多个，多个腔体单元中的每个腔体单元分别与一个或者多个入口连通；出口的数量为多个，多个腔体单元中的每个腔体单元分别与一个或者多个出口连通；紫外光源的数量为多个，多个腔体单元中的每个腔体单元分别与一个或者多个紫外光源对应，腔体单元对应的紫外光源用于向腔体单元内发出紫外光。这样，待杀菌物可以由多个入口分散进入多个腔体单元内，并通过多个紫外光源分别进行杀菌消毒处理，由此能够提高对待杀菌物的杀菌均匀性，杀菌消毒处理后的待杀菌物由多个出口排出。
可选地，杀菌消毒装置还包括多个第二隔板，多个腔体单元中的每个腔体单元内分别设有一个或者多个第二隔板，第二隔板用于延长腔体单元内由入口至出口的通道路径。这样，待杀菌物在腔体内由入口至出口的流动时间较长，杀菌消毒效率较高。
可选地，腔体单元对应的紫外光源的数量为多个，多个紫外光源沿腔体单元内由入口至出口的通道路径的延伸方向依次设置。这样，可以通过多个紫外光源对腔体单元内流动的待杀菌物进行多次杀菌，因此能够进一步提高杀菌消毒装置的杀菌消毒效率。
可选地，第一隔板和第二隔板均为透光板。这样，多个腔体单元内的紫外光可以相互渗透，因此可以提高紫外光的利用率。

可选地，紫外光源位于壳体外，壳体上设有透光壁板区域，紫外光源发出的紫外光能够由该透光壁板区域射入腔体内。这样，将紫外光源设置于壳体外，避免紫外光源占用壳体的内部空间，防止紫外光源与待杀菌物之间产生相互干扰，比如防止紫外光源与水、水蒸气等待杀菌物之间产生电性干扰。
可选地，壳体本体的材料为透光材料。透光材料能够透光，便于在壳体上设置透光壁板区域，以使位于壳体外的紫外光源发出的紫外光能够穿过该透光壁板区域射入腔体内。具体地，透光壁板区域只需在壳体本体的某部分区域的内表面不设置紫外光反射层即可形成，此操作简单，无需复杂的装配操作。

可选地，壳体还包括设置于第一壁板的边沿一周与第二壁板之间的第三壁板，紫外光源设置于第三壁板的背离腔体的一侧，透光壁板区域设置于第三壁板上。这样，紫外光源设置于第三壁板的外侧，在将该杀菌消毒装置应用于口罩时，有利于紫外光源散热，从而不需要额外增加散热板。

图3为图1所示口罩中口罩本体、密封圈和配件孔盖的爆炸图。如图3所示，口罩本体1上设有通气口11，佩戴者(包括人或者动物)可由该通气口11吸入外界环境中的新鲜空气，并将呼出的气体排出至外界环境中。
需要说明的是，口罩本体1的内侧是指口罩本体1在佩戴至佩戴者的口鼻处时，朝向佩戴者的一侧。相应的，口罩本体1的外侧是指口罩本体1在佩戴至佩戴者的口鼻处时，背离佩戴者的一侧。
为了避免佩戴者由口罩本体1的边沿与佩戴者之间的间隙吸入或者呼出气体，在一些实施例中，如图1和图3所示，口罩还包括密封圈3。该密封圈3的材料包括但不限于硅胶等亲肤材料，密封圈3围绕口罩本体1的边沿一周设置。具体地，密封圈3可以通过粘接、熔接等方式固定于口罩本体1的边沿一周，在此不做具体限定。当口罩本体1佩戴至佩戴者的口鼻处时，密封圈3能够密封口罩本体1的边沿一周与佩戴者之间的间隙，防止佩戴者由该间隙吸入或者呼出空气，由此使得佩戴者能够集中 由通气口11吸入或呼出气体，以便于对佩戴者吸入或者呼出的气体进行集中处理。
在一些实施例中，如图1和图3所示，口罩本体1上设有至少一个配件孔12。具体地，该至少一个配件孔12的数量可以为一个，也可以为两个或者两个以上，在此不做具体限定。在一些实施例中，如图3所示，该至少一个配件孔12的数量为两个。
配件孔12用于连接外接配件，该外接配件包括但不限于电熏药包(比如针对哮喘的舒缓剂药包或者针对清新口气的口气清新剂药包)、医疗设备(比如雾化器或者氧气瓶)、电子配件(比如麦克风或者运动配件)、非电子类配件(比如饮水吸管)等。配件孔12上可拆卸连接有配件孔盖4，该配件孔盖4用于打开或者关闭该配件孔12。当需要在配件孔12上连接外接配件时，则通过配件孔盖4打开该配件孔12，以露出配件孔12；当配件孔12上不需要连接外接配件时，则通过配件孔盖4关闭该配件孔12，以保证口罩本体1的气密性。
在上述实施例中，配件孔盖4与配件孔12处的口罩本体边沿之间可以通过螺纹连接，也可以通过卡扣连接，在此不做具体限定。
在一些实施例中，配件孔盖4与配件孔12处的口罩本体边沿之间通过螺纹连接，螺纹连接的可靠性高，气密性好，能够保证口罩本体1的气密性。
进一步地，配件孔盖4与配件孔12处的口罩本体边沿之间设有橡胶垫。这样，通过橡胶垫能够密封配件孔盖4与配件孔12处的口罩本体边沿之间的间隙，提高口罩本体1的气密性。
图4为图1所示口罩的爆炸图。如图4所示，口罩包括杀菌消毒装置5，该杀菌消毒装置5位于口罩本体1的外侧并与口罩本体1相对固定。杀菌消毒装置5的入口100与口罩本体1的外侧空间连通，杀菌消毒装置5的出口200与通气口11连通。杀菌消毒装置5采用紫外光对由入口100进入的空气进行杀菌消毒处理，杀菌消毒处理后的空气由出口200排出至通气口11，并能够由通气口11排入口罩本体1的内侧，以被佩戴者的口鼻吸入，由此防止佩戴者吸入环境中的病毒或者细菌。同时，杀菌消毒装置5还采用紫外光对佩戴者呼出的气体进行杀菌消毒处理，处理后的气体由入口100排出至外界环境中，以防止佩戴者呼出的携带病菌或者细菌的气体污染外界环境。由此，实现了口罩的防疫功能。
在一些实施例中，如图4所示，口罩还包括外挡板6。该外挡板6的材料包括但不限于塑胶、轻质金属或合金。外挡板6设置于口罩本体1的外侧并与该口罩本体1相对固定。杀菌消毒装置5位于该外挡板6与口罩本体1之间，外挡板6上设有过滤孔阵列61，该过滤孔阵列61与杀菌消毒装置5的入口100连通。
这样，可以通过外挡板6阻止外界环境中的大颗粒粉尘进入口罩内，同时还可以达到稳定气流的目的。
杀菌消毒装置5和外挡板6可以依次通过粘接、卡接、螺纹连接的方式与口罩本体1相对固定，在此不做具体限定。
在一些实施例中，如图4所示，口罩本体1的外表面上设有连接环13，该连接环13围绕通气口11的边沿一周设置。如图4所示，口罩还包括套筒8。该套筒8的材料包括但不限于塑胶、轻质金属或合金，套筒8沿自身轴向上的两端分别为第一端81和第二端82，套筒8的第一端81与连接环13连接，套筒8的第二端82向远离口罩 本体1的方向延伸。杀菌消毒装置5和外挡板6设置于套筒8内。连接环13能够阻止杀菌消毒装置5由套筒8的第一端81的开口掉出。套筒8的第二端82设有向套筒8内弯折的止挡翻边83，该止挡翻边83能够阻止外挡板6由套筒8的第二端82的开口掉出。由此采用套筒8与连接环13配合固定了杀菌消毒装置5、外挡板6和口罩本体1之间的相对位置。同时，套筒8还对杀菌消毒装置5和外挡板6进行了防水、防尘、防磨损保护，且当套筒8由金属材料制作时，还可以对杀菌消毒装置5起到散热的作用。
在上述实施例中，套筒8的第一端81与连接环13之间可以通过螺纹连接、卡接、粘接等方式连接，在此不做具体限定。
在一些实施例中，套筒8的第一端81与连接环13之间通过螺纹连接，螺纹连接的稳定性好，气密性高，能够提高口罩的气密性。且套筒8与连接环13之间可拆卸，便于维修和更换。
在一些实施例中，套筒8的第一端81与连接环13之间设有密封圈，该密封圈用于密封套筒8的第一端81与连接环13之间连接间隙，以进一步保证口罩的气密性。
在一些实施例中，如图4所示，口罩还包括过滤器7。该过滤器7设置于杀菌消毒装置5的出口200与通气孔11之间。过滤器7用于滤除颗粒物、水蒸气和二氧化碳。这样，过滤器7可以阻止颗粒物、水汽和二氧化碳进入通气口11内，同时，过滤器7还可以吸收杀菌消毒装置5泄漏的紫外光，避免紫外光对佩戴者造成辐射伤害。
在一些实施例中，如图4所示，过滤器7包括过滤器外壳71和设置于该过滤器外壳71内的过滤器内芯72。过滤器外壳71的材料包括但不限于塑胶、轻质金属或者合金，过滤器内芯72包括但不限于活性炭、干燥剂颗粒、二氧化碳固体吸收剂等过滤物，过滤器内芯72通过过滤器外壳71与口罩本体1相对固定。
在一些实施例中，如图4所示，过滤器外壳71包括相对的第一端和第二端。过滤器外壳71的第一端形成开口711，过滤器内芯72能够由该开口711安装于过滤器外壳71内或者由过滤器外壳71内取出。图5为图4所示口罩中杀菌消毒装置与过滤器的爆炸图。如图5所示，过滤器外壳71的开口711与杀菌消毒装置5的出口200相对，且开口711所处的过滤器外壳的边沿一周连接于杀菌消毒装置5上。过滤器外壳71的第二端的壁板上设有通气孔712，该通气孔712与通气口11相对并连通。这样，通过杀菌消毒装置5封堵了过滤器外壳71的开口711，以将过滤器内芯72保持于过滤器外壳71内。这样，过滤器外壳71无需设计成全封闭的壳体结构，由此能够减小过滤器外壳71在口罩的进出气路径上的厚度，从而有利于减小口罩的体积，减轻口罩的重量。
在上述实施例中，通气孔712的数量为多个，多个通气孔712阵列设置于过滤器外壳71的第二端的壁板上。
具体地，开口711所处的过滤器外壳的边沿一周可以通过粘接、卡接、螺纹连接等方式连接于杀菌消毒装置5上，在此不做具体限定。
可以知道的是，过滤器7也可以设置于过滤孔阵列61与杀菌消毒装置5的入口100之间，还可以设置于其他位置，在此不做具体限定。图4仅给出了过滤器7设置于杀菌消毒装置5的出口200与通气孔11之间的示例，并不能认为是对本申请构成的 限定。
本申请还提供一种杀菌消毒装置，该杀菌消毒装置为上述具有杀菌消毒功能的设备中的杀菌消毒装置。
图6为本申请一些实施例提供的杀菌消毒装置的爆炸图。如图6所示，杀菌消毒装置5包括壳体51。壳体51包括壳体本体和设置于该壳体本体的内表面的紫外光反射层，紫外光反射层用于反射紫外光。
壳体本体的材料包括但不限于塑胶、轻质金属或者合金。在一些实施例中，壳体本体的材料为塑胶，塑胶的密度较小，成本较低，能够减轻壳体51的重量，降低壳体51的成本。
紫外光反射层可以设置于壳体本体的内表面的部分区域，也可以设置于壳体本体的内表面的全部区域，在此不做具体限定。紫外光反射层在壳体本体的内表面的设置面积越大，紫外光的反射率越高。
紫外光反射层可以为贴设于壳体本体的内表面的微棱镜型反光膜，也可以为采用电镀、化学沉积、二次注塑成型等工艺成型于壳体本体的内表面的一层紫外光反射材料，该紫外光反射材料包括但不限于铝材料、铝合金材料、聚四氟乙烯(polytetrafluoroethylene，PTFE)，在此不做具体限定。
可以知道的是，壳体本体的材料也可以与紫外光反射层的材料一致，且壳体本体与紫外光反射层一体成型。这样，壳体51的组成结构简单，容易加工制作。
壳体51内设有腔体53，壳体51的紫外光反射层形成腔体53的内表面，壳体51上设有入口100和出口200，入口100和出口200均与腔体53连通。待杀菌物由入口100进入腔体53，并在腔体53内进行杀菌消毒处理，杀菌消毒处理后的待杀菌物由出口200排出腔体53。
如图6所示，杀菌消毒装置5还包括紫外光源52。可选地，紫外光源52为C波段紫外光发光二极管(ultraviolet c light-emitting diode，UVC-LED)，UVC-LED发出的紫外光波长为200nm～280nm，能够用于消毒杀菌消毒处理。紫外光源52用于向腔体53内发出具有杀菌消毒作用的紫外光(也即是UVC)。
这样，在将该杀菌消毒装置应用于具有杀菌消毒功能的设备中时，比如应用于图4所示口罩时，待杀菌物(比如空气)由入口100进入腔体53后，被紫外光源52发出的紫外光照射，部分紫外光被待杀菌物吸收，以消灭待杀菌物中携带的病毒和细菌，未被待杀菌物吸收的部分紫外光照射至腔体53的内表面，并被构成腔体53的内表面的紫外光反射层反射，以使得未被吸收的部分紫外光再次经过待杀菌物，由此可以对待杀菌物进行第二次杀菌消毒处理，若在第二次杀菌消毒处理时，还存在未被待杀菌物吸收的部分紫外光，则该部分紫外光还能够被构成腔体53的内表面的紫外光反射层再次反射，以对待杀菌物进行第三次杀菌消毒处理，由此依次对待杀菌物进行多次杀菌消毒处理，直至紫外光全部被待杀菌物吸收掉，从而能够提高紫外光的利用率。同时，紫外光的传播速度较快，无论是对静置于腔体的固体待杀菌物，还是对流经腔体的液体或者气体待杀菌物，均可进行多次杀菌消毒处理，因此杀菌消毒效率较高。
为了提高杀菌消毒装置5的杀菌均匀性，在一些实施例中，杀菌消毒装置5还包括至少一个第一隔板。该至少一个第一隔板设置于腔体53内，且该至少一个第一隔板 将该腔体53分隔为多个彼此独立的腔体单元。
腔体53被第一隔板分隔成的腔体单元的数量可以为两个、三个、四个等等，在此不做具体限定。
示例的，如图6所示，杀菌消毒装置5包括两个相互垂直的第一隔板54，该两个第一隔板54将腔体53分隔为四个彼此独立的腔体单元，分别为腔体单元53a、腔体单元53b、腔体单元53c和腔体单元53d。
入口100的数量为多个，多个腔体单元中的每个腔体单元分别与一个或者多个入口100连通。这样，待杀菌物可以由多个入口100分散进入多个腔体单元内。
在上述实施例中，多个腔体单元中的每个腔体单元可以分别与一个入口100连通，也可以分别与多个入口100连通，在此不做具体限定。图6仅给出了多个腔体单元中的每个腔体单元分别与一个入口100连通的示例，并不能认为是对本申请构成的限定。
紫外光源52的数量为多个，多个腔体单元中的每个腔体单元分别与一个或者多个紫外光源52对应。可以知道的是，腔体单元与紫外光源52对应，也即是紫外光源52发出的具有杀菌消毒作用的紫外光照射至该腔体单元内，换句话说，也即是，腔体单元对应的紫外光源52用于向该腔体单元内发出具有杀菌消毒作用的紫外光。这样，多个紫外光源52可以对多个腔体单元内的待杀菌物进行分别杀菌消毒处理，由此能够提高对待杀菌物的杀菌均匀性。
在上述实施例中，多个腔体单元中的每个腔体单元可以分别与一个紫外光源52对应，也可以分别与多个紫外光源52对应，在此不做具体限定。图6仅给出了多个腔体单元中的每个腔体单元分别与两个紫外光源52对应的示例，并不能认为是对本申请构成的限定。
出口200的数量为多个，多个腔体单元中的每个腔体单元分别与一个或者多个出口200连通。这样，多个腔体单元内杀菌消毒处理后的待杀菌物可以由多个出口200排出。
在上述实施例中，多个腔体单元中的每个腔体单元可以分别与一个出口200连通，也可以分别与多个出口200连通，在此不做具体限定。图6仅给出了多个腔体单元中的每个腔体单元分别与一个出口200连通的示例，并不能认为是对本申请构成的限定。
当待杀菌物为流体时，待杀菌物由入口100流入腔体53并由出口200流出，为了延长待杀菌物在腔体53内的流动时间，以使待杀菌物与紫外光源52发出的紫外光充分接触，在一些实施例中，如图6所示，杀菌消毒装置5还包括多个第二隔板55，多个腔体单元中的每个腔体单元内分别设有一个或者多个第二隔板55。图8为图6所示的杀菌消毒装置的主视图，如图8所示，第二隔板55能够延长腔体单元内由入口100至出口200的通道路径。这样，待杀菌物在腔体53内流动的时间较长，杀菌消毒效率较高。
在上述实施例中，多个腔体单元中的每个腔体单元内可以分别设有一个第二隔板55，也可以分别设有多个第二隔板55，在此不做具体限定。图6仅给出了多个腔体单元中的每个腔体单元内分别设有一个第二隔板55的示例，并不能认为是对本申请构成的限定。
需要说明的是，第二隔板55延长腔体单元内由入口100至出口200的通道路径， 也就是说，第二隔板55位于腔体单元内由入口100至出口200的直线路径中，由入口100流入腔体53的待杀菌物需要绕过第二隔板55才能由出口200排出，且待杀菌物在腔体单元内由入口100至出口200的流动路径长度大于由入口100至出口200的直线路径长度。第二隔板55可以与入口100至出口200的直线路径垂直，也可以与入口100至出口200的直线路径呈一定夹角，该夹角小于90°，在此不作具体限定，只要能够使得由入口100流入腔体53的待杀菌物需要绕过该第二隔板55才能由出口200排出即可。
为了进一步提高杀菌消毒装置5的杀菌消毒效率，在一些实施例中，如图8所示，腔体单元对应的紫外光源52的数量为多个，多个紫外光源52沿腔体单元内由入口100至出口200的通道路径的延伸方向依次设置。这样，可以通过多个紫外光源52对腔体单元内流动的待杀菌物进行多次杀菌，因此能够进一步提高杀菌消毒装置5的杀菌消毒效率。
在上述实施例中，每个腔体单元对应的紫外光源52的数量可以为两个、三个、四个等等，在此不做具体限定。紫外光源52的设置数量越多，杀菌消毒效率越高，而相应的，杀菌消毒装置5在工作时的发热量也越大，在将该杀菌消毒装置5应用于口罩时，对佩戴者的嘴部造成的不适感也越强。为了避免此问题，在一些实施例中，如图6和图8所示，每个腔体单元对应的紫外光源52的数量为两个，这样，每个腔体单元对应的紫外光源52的数量适中，能够同时兼顾杀菌消毒效率和发热量。
第一隔板54和第二隔板55可以为表面设置有紫外光反射层的塑胶板、轻质金属板或者合金板等等，第一隔板54和第二隔板55也可以为透光板，在此不作具体限定。
在一些实施例中，第一隔板54和第二隔板55均为透光板。这样，多个腔体单元内的紫外光可以相互渗透，因此可以提高紫外光的利用率。
壳体51可以为一个结构件整体，也可以为可拆卸的多个结构件，在此不做具体限定。
在一些实施例中，如图6所示，壳体51包括底座511和盖板512。底座511包括底板和设置于底板边沿的侧板，底板和侧板围成腔体53，腔体53的远离底板的一端开口。盖板512盖设于腔体53的远离底板的一端开口处，且盖板512与底座511可拆卸连接。这样，壳体51由多个结构件可拆卸连接而成，便于壳体51的加工制作。
在上述实施例中，可选地，如图6所示，第一隔板54和第二隔板55固定于底座512内。图7为图6所示的杀菌消毒装置在另一方位下的爆炸图，如图7所示，盖板512的内表面上设有第一凹槽512a和第二凹槽512b，第一隔板54的靠近盖板512的一端配合伸入第一凹槽512a内，第二隔板55的靠近盖板512的一端配合伸入第二凹槽512b内。这样，可以避免第一隔板54与盖板512之间、以及第二隔板55与盖板512之间存在间隙，由此保证了被第一隔板54分隔成的多个腔体单元之间的独立性。
在上述实施例中，盖板512的内表面是指盖板512的朝向腔体53的表面。
入口100和出口200可以设置于壳体51的相对两个壁板上，也可以设置于壳体51的相邻两个壁板上，还可以设置于壳体51的同一壁板上，在此不作具体限定。
在一些实施例中，如图6所示，壳体51包括相对的第一壁板51a和第二壁板51b，入口100设置于第一壁板51a上，出口200设置于第二壁板51b上。这样，入口100 和出口200设置于壳体51的相对两个壁板上，此结构简单，且在将该杀菌消毒装置5应用于图4所示口罩时，口罩的外挡板6、杀菌消毒装置5、过滤器7可以沿直线排列，由此能够减小由外挡板6、杀菌消毒装置5、过滤器7组成的结构在口罩本体1上的占用面积。
在上述实施例中，入口100和出口200可以相对设置，也可以错位设置，在此不做具体限定。
在一些实施例中，如图8所示，入口100靠近第一壁板51a的边沿设置，出口200靠近第二壁板51b的中心设置。这样，入口100与出口200错位设置，可以延长腔体53内由入口100至出口200的通道路径，延长待杀菌物在腔体53内流动的时间，提高杀菌消毒装置5的杀菌消毒效率。
紫外光源52可以位于壳体51内，也可以位于壳体51外，只要紫外光源52发出的紫外光能够射入腔体53内即可，在此不做具体限定。
在一些实施例中，如图6所示，紫外光源52位于壳体51外，壳体51上设有透光壁板区域300。透光壁板区域300为壳体51上由透光玻璃、透光塑胶等透光材料制作的部分。紫外光源52发出的紫外光能够由该透光壁板区域300射入腔体53内。
这样，将紫外光源52设置于壳体51外，避免紫外光源52占用壳体51的内部空间，防止紫外光源52与待杀菌物之间产生相互干扰，比如防止紫外光源52与水、水蒸气等待杀菌物之间产生电性干扰。
在一些实施例中，壳体本体的材料为透光材料，透光材料能够透光，便于在壳体51上设置透光壁板区域300，以使位于壳体51外的紫外光源52发出的紫外光能够穿过该透光壁板区域300射入腔体53内。具体地，透光壁板区域300只需在壳体本体的某部分区域的内表面不设置紫外光反射层即可形成，此操作简单，无需复杂的装配操作。
如图7所示，可选地，壳体51的外表面设有安装凹槽513，紫外光源52安装于该安装凹槽513内。这样，能够避免紫外光源52凸出壳体51外而增大了杀菌消毒装置5的体积。
具体地，紫外光源52可以设置于壳体51的第一壁板51a的外侧，也可以设置于壳体51的第二壁板51b的外侧，还可以设置于壳体51的其他壁板的外侧，在此不做具体限定。
在一些实施例中，如图6所示，紫外光源52设置于第二壁板51b的远离第一壁板51a的一侧，透光壁板区域300设置于第二壁板51b上。这样，紫外光源52设置于第二壁板51b的外侧，紫外光源52发出的紫外光与腔体53内由入口100至出口200流动的待杀菌物逆向接触，能够提高杀菌消毒效率。
在另一些实施例中，图9为本申请另一些实施例提供的杀菌消毒装置的爆炸图，如图9所示，壳体51还包括设置于第一壁板51a的边沿一周与第二壁板51b之间的第三壁板51c，紫外光源52设置于第三壁板51c的背离腔体53的一侧，透光壁板区域300设置于第三壁板51c上。这样，紫外光源52设置于第三壁板51c的外侧，在将该杀菌消毒装置5应用于图4所示口罩时，可以将套筒8设计成由金属导热材料制作，并通过该套筒8对紫外光源52进行散热处理，从而不需要额外增加散热板。由此可以 减小杀菌消毒装置5在口罩的进出气路径上的厚度。
在一些实施例中，如图6或图9所示，杀菌消毒装置5还包括电路板56。该电路板56设置于第二壁板51b的远离第一壁板51a的一侧，且该电路板56与第二壁板51b层叠设置，紫外光源52与电路板56电连接。这样，通过电路板56对紫外光源52进行统一供电管理。
可以知道的是，电路板56也可以设置于第一壁板51a的远离第二壁板51b的一侧，电路板56还可以设置于第三壁板51c的外侧，在此不做具体限定。图6或图9仅给出了电路板56设置于第二壁板51b的远离第一壁板51a的一侧的示例，并不能认为是对本申请构成的限定。
当电路板56设置于第二壁板51b的远离第一壁板51a的一侧，且紫外光源52设置于第三壁板51c的背离腔体53的一侧时，紫外光源52与电路板56之间可以通过导线电连接，也可以通过柔性电路板(flexible printed circuit，FPC)电连接，在此不做具体限定。在一些实施例中，如图9所示，紫外光源52与电路板56之间通过柔性电路板60电连接。
当电路板56设置于第二壁板51b的远离第一壁板51a的一侧时，为了避免电路板56遮挡第二壁板51b上的出口200，在一些实施例中，如图7所示，电路板56上与出口200相对的位置设有避让口561，第二壁板51b的外表面上围绕出口200的边缘一周设有隔离套筒511a，隔离套筒511a穿设于避让口561内。这样，一方面，能够避免电路板56遮挡第二壁板51b上的出口200，另一方面能够避免出口200流出的待杀菌物与电路板56接触干扰。
在一些实施例中，为了对电路板进行散热处理，在一些实施例中，如图4所示，杀菌消毒装置5还包括散热板50。散热板50的材料包括但不限于铝、铝合金、铜、铜合金等金属材料，该散热板50设置于电路板56的背离壳体51的第二壁板的一侧，并与电路板56接触。这样，通过散热板50能够带走电路板56以及电路板56上的紫外光源产生的热量，延长紫外光源和电路板的使用寿命，避免因电路板和紫外光源的热量过高而而烧坏电路板或者紫外光源。
在一些实施例中，如图6所示，杀菌消毒装置5还包括充电电池57和充电接口58，充电电池57和充电接口58均设置于电路板56上，充电电池57用于向紫外光源52供电，充电接口58用于向充电电池57补充电量。这样，可通过充电接口58向充电电池57充电，以使杀菌消毒装置5能够长久使用。
为了减小杀菌消毒装置5的体积，在一些实施例中，如图7所示，壳体51的外表面设有容纳槽511b，充电电池57设置于电路板56的朝向壳体51的表面，且充电电池57配合容纳于该容纳槽511b内。这样，使电路板56与壳体51的外表面紧密贴合，以减小杀菌消毒装置5的体积。
在一些实施例中，杀菌消毒装置5还包括开关，该开关设置于电路板56上，该开关用于控制杀菌消毒装置5的开启或者关闭。具体地，该开关可以为按钮开关或者触摸开关。
在一些实施例中，杀菌消毒装置5还包括无线连接模块，该无线连接模块设置于电路板56上，且该无线连接模块可以与手机、配件等建立连接，以传送指令和数据， 在此不做具体限定。
在一些实施例中，如图6所示，杀菌消毒装置5还包括指示灯59，该指示灯59用于指示杀菌消毒装置5的开启和关闭以及充电电池57的电量情况。
在一些实施例中，杀菌消毒装置5还包括传感器和控制单元，传感器用于检测腔体53内待杀菌物的成分或者运动频率，控制单元与传感器连接，控制单元用于根据传感器的检测结果，控制图4所示口罩的配件孔12所连接的外接配件。示例的，控制单元在传感器检测到腔体53内的空气流动频率大于预设阈值时，确定佩戴者是哮喘发作，并控制已装配至配件孔12上的电熏药包配件释放舒缓剂。又示例的，控制单元在传感器检测到佩戴者呼出的空气中有异味时，控制已装配至配件孔12上的口气清新配件释放口气清新剂。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
