本申请涉及照明和杀菌设备技术领域，特别涉及一种杀菌装置。
背景技术
中功率和大功率紫外线消毒灯通常是指功率高于20W的灯具，其发出的强紫外线具有很好的杀菌消毒效果，可以缩短杀菌时间，强紫外线灯具的杀菌消毒方式主要有直射式、换气式和平射式三种，其工作特点如下：
(1)直射式紫外灯：将紫外线直接暴露在敞开的环境中进行杀菌消毒，可以对物体表面和空气进行消毒，杀菌消毒效率高；但杀菌时人需要离开杀菌场所，安全等级低。
(2)换气式紫外灯：将空气吸入封闭的灯具内腔，在灯具内腔经过紫外线消毒后，再将已杀菌空气排出到灯具外面，完成空气杀菌消毒和换气，多用于对空气进行消毒，杀菌时人不需要离开杀菌场所，可避免紫外线射伤人员，安全等级高；但杀菌效率低，换气过程易产生噪音，并且产品通常设计成大尺寸的机柜结构，导致体积大、重量重。
(3)平射式紫外灯：将紫外线灯安装在2.1米以上的高度(即上层空间)，以对上层空间进行杀菌消毒，人可在2.1米以下的空间活动，安全等级高，杀菌时人不需要离开杀菌场所；但相关技术中，平射式紫外灯对下层空间的空气杀菌效果很差，并且产品通常设计成大尺寸的机柜结构，导致体积大、重量重。
为了提高紫外线杀菌灯具的使用安全，并克服换气式和平射式紫外灯杀菌效率低的缺陷，换气式紫外线灯需要提高空气换气效率，即增大灯具内腔并提高风机功率，而平射式紫外线灯需要采用大功率的紫外线光源并使紫外线射出的更远。这就导致换气式紫外灯和平射式紫外灯结构复杂、体积大、重量重，进而导致产品安装困难、成本高。
上述内容仅用于辅助理解本发明的技术方案，并不代表承认上述内容是 现有技术。
申请内容
本申请的主要目的是提出一种杀菌装置，旨在解决现有强紫外线灯具杀菌效率低、结构复杂、体积大、重量重、安装困难、成本高的技术问题。
为实现上述目的，本申请提出的杀菌装置包括灯头、格栅组件、灯体、杀菌组件和风机组件，所述灯头和所述灯体分别设于所述格栅组件的两端；定义所述灯头、所述格栅组件和所述灯体的排布方向为第一方向；
所述格栅组件设有中心孔，所述格栅组件设有多个隔板，多个所述隔板间隔设置并形成有多个出光孔；多个所述出光孔与所述中心孔连通，多个所述出光孔沿所述格栅组件的周向延伸设置，并且多个所述出光孔的出光方向与所述第一方向垂直；
所述杀菌组件设于所述中心孔内，所述杀菌组件用于发射紫外线，一部分所述紫外线沿所述出光孔射出；
所述灯体的底部设有第一过气孔，所述第一过气孔与所述中心孔连通；
所述风机组件对应所述第一过气孔设置，用于给所述杀菌装置换气。
本申请其他特征和相应的有益效果在说明书的后面部分进行阐述说明。
本申请的技术问题解决思路为：以杀菌装置为紫外线灯具为例，将紫外线灯具的紫外线光源设置成环形结构(可以是圆形、椭圆形、方形或其他环状结构)，在环状紫外线光源外侧对应设置格栅组件，通过格栅组件限定紫外线仅沿水平方向射出。同时，在紫外线灯具的底部设有风机和通风口(优选方案是：风机沿垂直向下方向吹风)，通过风机使上层空间的已杀菌空气更好的排走，促进上层空间的空气和下层空间的空气交换，扩大紫外线灯具对周围空气的杀菌范围，使其既可以对与格栅组件对应的水平空气直接杀菌消毒，又可以使水平空气和垂直空气更好的对流，实现对与格栅组件对应的水平层之外的其他区域的空气进行间接杀菌消毒。
相比普通的平射式紫外灯，新的紫外线灯具方案并没有采用增大紫外线光源功率使紫外线射出的更远，以扩大杀菌范围，而是通过在紫外线灯具的底部设置风机组件的方式，使上层平射式灯具可以间接的对下层空间的空气杀菌消毒。
格栅组件采用薄板冲压的工艺加工，可以大幅度降低格栅组件的重量；在格栅组件中心设有中心孔，并将紫外线光源模组(即杀菌组件)和风机组件等零部件设置在中心孔内，从而大幅度的压缩了灯具产品的尺寸。新方案的产品尺寸可以缩小到φ250×200MM，结构紧凑；而换气式紫外灯和平射式紫外灯通常设计成机柜的形式，产品最大尺寸通常会达到0.6米或1米以上，重量重，难以实现单个人安装。
此外，在格栅组件上部位置设有灯头，灯头用于固定安装紫外线灯具。灯头的形式可以是标准灯头结构、固定座结构、挂钩结构或嵌入式安装结构，以方便紫外线灯具与外部完成安装。本申请方案中，灯具产品尺寸可以缩小到250mm以内，重量可以降低到1.7Kg以内，当灯头为标准螺口灯头时，灯具可以当做电光源，直接安装在传统灯具内或安装在传统灯座上使用，电光源符合灯具产品安全认证要求，具有新的应用前景。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，下面通过具体实施方式结合附图对本申请实施例座进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请提出一种杀菌装置100，该杀菌装置100可以是一种紫外线杀菌灯，用于对空气进行杀菌。
在本申请实施例中，如图1、图2和图3所示，该杀菌装置100包括灯头1、格栅组件2、灯体3、杀菌组件4和风机组件5，灯头1和灯体3分别设于格栅组件2的两端；定义灯头1、格栅组件2和灯体3的排布方向为第一方向；
格栅组件2设有中心孔2a，格栅组件2设有多个隔板21，多个隔板21间隔设置并形成有多个出光孔2b；多个出光孔2b与中心孔2a连通，多个出光孔2b沿格栅组件2的周向延伸设置，并且多个出光孔2b的出光方向与第 一方向垂直；
杀菌组件4设于中心孔2a内，杀菌组件4用于发射紫外线，一部分紫外线沿出光孔2b射出；
灯体3的底部设有第一过气孔3a，第一过气孔3a与中心孔2a连通；
风机组件5对应第一过气孔3a设置，用于给杀菌装置100换气。
本实施例中，第一方向可以为重力方向，也即竖直方向。杀菌装置100可通过灯头1安装在待杀菌空间的上层空间，安装高度通常距离空间地面2.1米以上，实现对上层空间空气直接进行杀菌的目的。出光孔2b沿环绕格栅组件2的周向设置，出光孔的出光方向为水平方向。杀菌装置100通过杀菌组件4发射的紫外线进行杀菌。
本实施例中灯头1设于格栅组件2的顶部，用于杀菌装置100与外部的固定安装，可以通过标准螺口灯头结构、固定座结构或挂钩结构，以方便与外部连接完成安装。本申请中，参考图2，杀菌装置的产品外廓尺寸直径D可以缩小到250mm以内，重量可以降低到1.7Kg以内，当灯头为标准螺口灯头时，杀菌装置可以当做电光源，直接安装在传统灯具内或安装在传统灯座上使用，电光源符合灯具产品安全认证要求，具有新的应用前景。
本实施例中，杀菌组件4设于中心孔2a内。杀菌组件4可以是单根环形紫外线灯管，也可以是由多个紫外线模组沿周向排布而成；杀菌组件4还可以是多根环形紫外线灯管上下层叠设置在一起使用，以增加紫外线杀菌模组的功率。
本实施例中，杀菌组件4为环形灯管，格栅组件2为环形，使杀菌装置100安装时不受前后、左右限制，安装更灵活，还可以提高紫外线杀菌的范围。此外，环形灯管是独立的光源，可以使整体结构更加紧凑。
杀菌组件4可以为紫外线灯管，包含紫外线光源和对应的驱动电源，紫外线光源可以是紫外线LED灯珠组件、低压汞灯(LPM)、中高压汞灯、氙灯等气体放电类型的紫外线灯管光源中的一种或多种。
风机组件5的设置可以增强空气排出的风力，以及提高排风的风速，将空气排走的更快、更远，促进杀菌装置100外部已杀菌空气和待杀菌空气的交换和循环，提高空气杀菌效率。同时杀菌组件4发射的部分紫外线可以通过出光孔2b射出，可对外部的空气直接杀菌消毒；同时由于杀菌组件4和出光孔2b均 沿周向设置，可以增大紫外线直接杀菌消毒的有效面积。
本实施例中，以杀菌装置为紫外线灯具，杀菌组件4为紫外线灯管为例，紫外线灯管发出紫外线光源，将杀菌组件4设置成环形结构，当然也可以是圆形、椭圆形、方形或其他环状结构，在环状紫外线光源外侧对应设置格栅组件2，通过格栅组件2限定紫外线仅沿水平方向射出。同时，在杀菌组件4的底部设有风机组件5和第一过气孔2a，可选的，风机组件5沿垂直向下方向吹风，通过风机组件5使上层空间的已杀菌空气更好的排走，促进上层空间的空气和下层空间的空气交换，扩大杀菌组件4对周围空气的杀菌范围，使其既可以对与格栅组件2对应的水平空气直接杀菌消毒，又可以使水平空气和垂直空气更好的对流，实现对与格栅组件2对应的水平层之外的其他区域的空气进行间接杀菌消毒。
可以理解的是，风机组件5相对第一过气孔3a设置，缩短了由出光孔2b、中心孔2a和第一过气孔3a构成的风道距离，有助于提高换气效率。风机组件5的换气方式为，风机组件5沿第一方向吹风，出光孔2b为进气口，第一过气孔3a的出风口。或者，风机组件的换气方式为，风机组件沿所述第一方向的反方向吹风，出光孔2b为出风口，第一过气孔3a的进气口。
本实施例中通过隔板21之间间隔设置形成出光孔2b，可以限定紫外线只沿出光孔2b方向出光；出光孔2b沿格栅组件2的周向延伸，可以提高紫外线杀菌的范围和杀菌效率。一实施例中，出光孔2b的内壁面设置有吸光层，隔板21面向出光孔2b的一侧设有吸光层，减少紫外线在隔板21表面的反射，以防止紫外线多次反射后散乱的从出光孔2b射出。
如图1、图2和图5所示，多个所述隔板21沿所述第一方向呈平行且间隔设置，相邻的两个所述隔板21之间形成所述出光孔2b；每一所述隔板21的中部设有第一通孔，多个所述第一通孔连通并围合形成所述中心孔2a。
隔板21采用薄板冲压的工艺加工，可以大幅度降低格栅组件的重量；在格栅组件中心设有中心孔，并将杀菌组件和风机组件等零部件设置在中心孔内，从而大幅度的压缩了产品的尺寸。参考图2，本申请的产品外廓尺寸可以缩小到直径D为250mm，高度H为200mm，结构紧凑。
如图5所示，格栅组件2还设有多个连接柱22，连接柱22的外周侧设有多个限位槽，多个限位槽间隔设置，多个隔板21沿第一方向排布，每一隔板 21均设有定位孔21a，每一连接柱22穿设于多个定位孔21a内，且隔板21靠近定位孔21a的部分容纳于限位槽内。可以理解的是，通过连接柱22可实现多个隔板21的定位。
如图5所示，连接柱22包括定位件221和锁紧件222，定位件221的外周侧设有多个限位槽，每一定位件221穿设于多个定位孔21a内，通过定位件221可实现多个隔板21的定位。同时定位件221沿第一方向设有锁紧腔，锁紧件222穿设于锁紧腔内，锁紧件222的两端分别与灯体3和灯头1抵接，限定灯头1、格栅组件2和灯体3的位置关系，进而实现灯头1、格栅组件2的可拆卸连接，便于更换杀菌组件4。
在本申请的一实施例中，如图2所示，杀菌装置100还包括凸出部31，凸出部31设于中心孔2a内，并与第一过气孔3a对应设置，凸出部31连接灯头1和灯体3；杀菌组件4环绕凸出部31设置。
凸出部31设有第二过气孔31b，第一过气孔3a和中心孔2a分别与第二过气孔连通。
可以理解的是，杀菌组件发射的紫外线遇到凸出部31发生反射，可以使紫外线更多地沿出光孔2b反射出去。同时，凸出部31还可以用于固定杀菌组件4和/或风机组件5。
本实施例中，在凸出部31周侧或顶端设有第二过气孔31b，第一过气孔3a和中心孔2a分别与第二过气孔31b连通，可以保障杀菌装置能顺畅换气。
如图2所示，本实施例中，凸出部31与灯体3设置成一体结构，凸出部31朝向灯头1方向延伸。在又一些实施例中，凸出部31的两端分别与灯头1和灯体3可拆卸连接。
在本申请的另一实施例中，凸出部31也可连接灯头1或格栅组件。凸出部31与灯头1设置成一体结构或者可拆卸连接。可选的，凸出部31与灯头1设置成一体结构，凸出部31朝向灯体3方向延伸。
在本申请的又一实施例中，凸出部31连接灯体3。凸出部31与灯体3设置成一体结构或者可拆卸连接。
在本申请的一实施例中，如图2、图3和图4所示，凸出部设有第一容置腔31a，第一过气孔3a和第二过气孔31b分别与第一容置腔31a连通；杀菌装置100还包括遮光罩6，遮光罩6为抗紫外线材质。遮光罩6设于第一容置 腔31a内，遮光罩6设有第三过气孔6a，第三过气孔6a与第二过气孔31b错位设置，防止紫外线沿第二过气孔31b射出至风机组件或沿第一过气孔3a射出至杀菌装置外面。
可以理解的是，在遮光罩设置第三过气孔6a，可保障出光孔2b、中心孔2a、第二过气孔31b、第一容置腔31a和第一过气孔3a的连通状态，保障空气的流通，提高了杀菌效率。
可以理解的是，当第二过气孔31b设置在凸出部31的顶端时，由于凸出部31的顶端与杀菌组件存在高度差，杀菌组件射出的紫外线不会第二过气孔31b射出，那么杀菌装置可以不用设置遮光罩6。第二过气孔31b设置在凸出部31的周侧面时，可以使杀菌装置换气更顺畅。
在本申请的一实施例中，杀菌装置还包括反射罩(图中未示出)，反射罩设于杀菌组件靠近凸出部的内侧，一部分所述紫外线经反射罩反射后沿所述出光孔射出。
可以理解的是，发射罩设于杀菌组件与凸出部之间，通过设置反射罩，可将射向凸出部方向的紫外线发射，并使反射后的紫外线沿出光孔射出，可提高杀菌效果和效率。
在本申请的一实施例中，如图2所示，凸出部与灯体设置成一体结构，凸出部31的一端的周缘与第一过气孔3a的孔壁连接，且凸出部31与灯体3的连接处弧形过渡且呈喇叭状。
凸出部31与灯体3一体加工成型，且连接处弧形过渡且呈喇叭状，可以使灯具换气更顺畅，同时还可以使灯体3结构简单，加工成本低。灯体3采用金属材质，易成形加工，还可以抗紫外线。本实施例中灯体3和凸出部31均为钣金结构。
一实施例中，风机组件5设于述凸出部31与灯体3的连接处。另一实施了中，风机组件5设于所述第一容置腔31a内。风机组件5的上述位置设计可以使得杀菌装置的整体结构紧凑，减小产品尺寸，缩短产品进风口和出风口的间距。
在本申请的一实施例中，如图1、图2和图3所示，灯体3背离格栅组件2的一侧还设有底罩8，底罩8设有多个第四过气孔8b，第四过气孔8b与第一过气孔3a连通；参考图8，定义第四过气孔8b的宽度为R1，R1﹤6.5mm。 本实施例中，底罩8的材质为透光PC材质。将第四过气孔8b的宽度尺寸限定为小于6.5mm，可防止手指穿过第四过气孔8b，接触到风机组件5或其他带电体，保障使用安全。6.5mm的宽度尺寸是根据产品特征并结合灯具安全认证时所采用的测试指尺寸而设定，可提高产品的防触电等级，从而可以使用成更低的非隔离的电源或选用其他电气安全更低的电子元件。
本实施例中，第四过气孔8b的孔壁的延伸方向与第一方向呈夹角设置，也即所述第四过气孔8b的孔壁相对风扇组件5的空气流动方向呈倾斜设置，倾斜设置可以使第四过气孔8b的孔隙具有足够的宽度以保障出风顺畅，同时倾斜设置保障在外部异物插入第四过气孔8b时，特别是沿平行于第一方向插入第四过气孔8b时，起到一定的阻挡作用。第四过气孔8b的这种交错式的倾斜设计方案，兼顾很好的防护效果和出风效率，也适合零件注塑或压铸加工时模具脱模，方便和风机外壳51一起加工。
参考图8，第四过气孔8b相对风扇组件5的进风或出风方向(也即第一方向)倾斜设置，倾斜设置使第四过气孔8b的两个孔壁之间形成的孔隙既保留了垂直方向的较窄的间距R2，避免垂直方向的较大异物插入至风扇；又保障了第四过气孔8b的孔隙具有有较宽的出风通道间距R3。其中尺寸关系为R3>R2>0mm。
本实施例中，如图2所示，底罩8靠近第四过气孔8b的位置设有倾斜面81，便于空气排出或进入。倾斜面81可以是锥形表面或圆弧表面，构成上窄下宽的孔结构。
在本申请的一实施例中，如图2和图3所示，杀菌装置100还包括照明组件7，底罩8与灯体3围合形成第二容置腔8a，照明组件7位于第二容置腔8a内。
可以理解的是，设置照明组件7，可使得杀菌装置100可提供照明功能。
一实施例中，如图2和图3所示，照明组件7设于灯体3面向第二容置腔8a的一侧，使风机组件5既可以完成杀菌空气交换，又可以给照明组件7散热。
照明组件7可以为LED照明模组，本实施例中LED照明模组的驱动电源设置在灯体3上，可以简化驱动电源的结构，节约成本。
在本申请的一实施例中，如图1、图2、图3、图6和图7所示，灯头1 包括：
第一壳体部11，第一壳体部11与格栅组件2连接；
第二壳体部12，第二壳体部12与第一壳体部11可拆卸连接或固定连接，第二壳体部12用于杀菌装置100对外安装固定。
可以理解的是，第二壳体部12与第一壳体部11可拆卸连接，可以更好的更换灯头的安装方式，便于杀菌装置100产品系列化扩展；同时还可以便于产品的组装和拆卸维修。
如图1、图2和图3所示，在本申请的一实施例中，第二壳体设有标准螺口结构时，可直接安装在传统灯具内或安装在传统灯座上使用。
或者，如图6和图7所示，在本申请的另一实施例中，第二壳体设有固定座结构，以与外部安装固定。第二壳体部12包括固定座121和安装板122，固定座121与第一壳体部11连接，固定座121背离第一壳体部11的一端设有安装凹槽12a，安装板122可拆卸地设于安装凹槽12a内。安装板122的一端沿第一方向延伸形成第一安装部123；第一安装部123设有第一安装孔123a；安装板122的另一端连接有插接件124，插接件124呈L型；固定座121还设有第一装配孔12b和第二装配孔12c，安装凹槽12a的两端分别与第一装配孔12b和第二装配孔12c连通，且固定座121设有第二安装孔121a，第二安装孔121a与第一装配孔12b连通；第二装配孔12c与插接件124适配；其中，插接件124插入第二装配孔12c内，第一安装部123插入第一装配孔12b内，使第一安装孔123a与第二安装孔121a对应设置，固定座121和安装板122通过穿设于第一安装孔123a和第二安装孔121a的紧固件15连接。使产品在高空安装时可以只用一个紧固件15，从而降低安装难度。紧固件15可以为螺栓或螺丝等，在此不做限定。
需要说明的是，安装板122可先安装于外部，然后将杀菌装置100的固定座121安装于安装板122，实现杀菌装置100的安装。
需要说明的是，第二壳体部设有第三容置腔1a，第三容置腔1a内设有控制电源，风机组件5和杀菌组件4分别与控制电源电连接。
本实施例中，如图2所示，风机组件5包括风机外壳51和风扇52，风扇52通过风机外壳51与灯体3连接，或，风扇52通过风机外壳51与底罩8连接。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的创造构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
