本申请要求于2024年4月16日提交中国专利局、申请号为202410460144.9发明名称为“防爆摄像机”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。
本申请涉及摄像机技术领域,尤其涉及一种防爆摄像机。
在一些涉及易爆炸性物质的生产、加工、储存和运输等场所的电气设备需要采取防爆措施,以避免成为危险点火源,例如在上述这些场所需要使用防爆摄像机。
然而,在符合隔爆设备行业和国家标准的情况下,现有的防爆摄像机比较笨重,无法满足轻量化要求。
发明内容
针对上述技术问题的至少一个方面,本申请实施例提供了一种防爆摄像机,防爆摄像机包括第一壳体和第二壳体,两个壳体分别形成第一隔爆腔体和第二隔爆腔体,两个隔爆腔体相互独立设置并分别用于安装主控模组和镜头模组,然后,本申请实施例将连接主控模组和镜头模组的线缆、以及连接两个壳体的传动组件设置在两个隔爆腔体的外侧,这样即可提升防爆摄像机的轻量化水平,从而解决了上述技术问题。
本申请实施例提供一种防爆摄像机,所述防爆摄像机包括:
具有第一隔爆腔体的第一壳体和具有第二隔爆腔体的第二壳体,所述第一隔爆腔体内安装有主控模组和第一电机,所述第二隔爆腔体内安装有镜头模组;
所述第一壳体沿第一方向的两端分别设有第一隔爆通孔和第二隔爆通孔,所述第一隔爆通孔安装有可转动地传动轴,所述传动轴伸入所述第一隔爆腔体的端部与所述第一电机传动连接,所述第二隔爆通孔用于供自所述主控模组伸出的线缆穿出;
所述第二壳体沿所述第一方向的两端分别延伸有第一转接轴,一对所述
第一转接轴共轴设置;
其中,一对所述第一转接轴通过自所述第一壳体延伸的一对安装耳可转动地安装于所述第一壳体;
并且,所述传动轴与同侧的所述第一转接轴之间通过传动组件传动连接,以使所述第一电机用于驱动所述第二壳体以所述第一方向为转轴方向自转,所述线缆从同侧的所述第一转接轴穿入所述第二隔爆腔体并与所述镜头模组连接,以使所述镜头模组受控于所述主控模组。
本申请实施例中提供的一个或多个技术方案,至少具有如下技术效果或优点:
本申请实施例提供了一种防爆摄像机,该防爆摄像机包括第一壳体和第二壳体,两个壳体分别具有第一隔爆腔体和第二隔爆腔体,第一隔爆腔体用于安装主控模组,第二隔爆腔体用于安装镜头模组;其中,沿第一方向,第一壳体的两端分别设有第一隔爆通孔和第二隔爆通孔,第一隔爆通孔安装有传动轴;第二壳体的两端分别延伸有第一转接轴,第二壳体的一对第一转接轴通过第一壳体的一对安装耳可转动地安装于第一壳体;然后,一方面,第一壳体内部(即第一隔爆腔体内)的第一电机通过传动轴和外部的传动组件即可驱动第二壳体转动;另一方面,第一壳体内部的主控模组伸出的线缆依次穿过第二隔爆通孔和同侧的一个第一转接轴即可连接至第二壳体内部(即第二隔爆腔体内)的镜头模组。
换言之,针对防爆摄像机较笨重的问题,本实施例通过相互独立的两个隔爆腔体分别封闭主控模组和镜头模组,然后,将不会产生电火花的传动组件和线缆设置在两个隔爆腔体的外部,由于隔爆腔体只需封闭主控模组和镜头模组,而将传动组件和线缆排除在隔爆腔体的外部,这样,相较将防爆摄像机的全部部件均设置的隔爆腔体内,减小了隔爆腔体的体积,即可大大减轻防爆摄像机的重量,满足防爆摄像机轻量化的要求,解决了现有防爆摄像机由于比较笨重无法满足轻量化要求的技术问题。

例实施例,显然,所描述的实施例仅仅是本申请的一部分实施例,而不是本申请的全部实施例,应理解,本申请不受这里描述的示例性实施例的限制。
图1~图4为防爆摄像机各视角的结构示意图,图5和图6为剖视图,图12为图5的局部放大图,结合图1~图6以及图12可见,该防爆摄像机包括具有第一隔爆腔体31的第一壳体10和具有第二隔爆腔体32的第二壳体20,第一隔爆腔体31内安装有主控模组和第一电机51,第二隔爆腔体32内安装有镜头模组22;第一壳体10沿第一方向X的两端分别设有第一隔爆通孔11和第二隔爆通孔12,第一隔爆通孔11安装有可转动的传动轴13,传动轴13伸入第一隔爆腔体31的端部与第一电机51传动连接,第二隔爆通孔12用于供自主控模组伸出的线缆70穿出;第二壳体20沿第一方向X的两端分别延伸有第一转接轴21,一对第一转接轴21共轴设置。该第一转接轴21设置在该第二壳体20上,例如,该第一转接轴21可以与第二壳体20一体形成,也可以固定安装在该第二壳体20上。
其中,一对第一转接轴21通过自第一壳体10延伸的一对安装耳14可转动地安装于第一壳体10;并且,传动轴13与同侧的第一转接轴21之间通过传动组件80传动连接,以使第一电机51用于驱动第二壳体20以第一方向X为转轴方向自转,线缆70从同侧的第一转接轴21穿入第二隔爆腔体32并与镜头模组22连接,以使镜头模组22受控于主控模组。
整体而言,关于满足防爆摄像机的轻量化要求,不同于现有防爆摄像机是将全部的部件放入隔爆腔体内,本申请是使用相互独立的两个隔爆腔体分别承载主控模组和镜头模组22,然后,将驱动镜头模组22转动的传动组件80和连接镜头模组22的线缆70设置在两个隔爆腔体的外部,从而可减小隔爆腔体的体积,使之满足轻量化的要求。
具体而言,关于第一壳体10,该第一壳体10具有第一隔爆腔体31,第一隔爆腔体31用于安装主控模组和第一电机51;然后,第一壳体10沿第一方向(例如为一水平方向)的两端分别设有第一隔爆通孔11和第二隔爆通孔12。
其中,一方面,第一隔爆通孔11处安装有传动轴13,传动轴13沿第一方向延伸,传动轴13例如可通过轴承等安装于第一隔爆通孔11,这样,传动轴13即可相对第一壳体10转动;并且,传动轴13伸入第一隔爆腔体31(或者说伸入第一壳体10内部)的端部与第一电机51传动连接,这样,能够理解,该第一电机51即可驱动传动轴13转动;另一方面,第一隔爆腔体31内部的主控模组连接有线缆70,线缆70可自第二隔爆通孔12穿出,能够理解,
该线缆70可用于连接至第二隔腔体20的镜头模组22。
具体而言,关于第二壳体20,该第二壳体20沿第一方向的两端分别延伸有第一转接轴21,两端的一对第一转接轴21共轴设置。
关于第一壳体10与第二壳体20的连接,一方面,第一壳体10沿第一方向的两端同向地延伸有一对安装耳14,这样,第二壳体20置于一对安装耳14之间时,该第二壳体20即可通过一对第一转接轴21可转动地安装于一对安装耳14,也就是可转动地安装于第一壳体10;然后,可在第一壳体10伸出的传动轴13与同侧的第一转接轴21之间设置传动组件80,能够理解,结合上面所说的第一电机51驱动传动轴13转动,该第一电机51通过传动轴13和传动组件80即可进一步驱动第二壳体20转动,该转动是第二壳体20以第一方向为转轴方向的自转,从而第二壳体20内的镜头模组22可对不同角度的视野进行拍摄。
另一方面,结合上面所说的线缆70自第一壳体10的第二隔爆通孔12穿出,该穿出的线缆70可进一步由同侧的第一转接轴21穿入第二隔爆腔体32内,从而可与镜头模组22电连接,能够理解,这样第二隔爆腔体32内的镜头模组22即可受控于第一隔爆腔体31内的主控模组。
可以看到,本实施例将容易产生电火花的器件(诸如主控模组、镜头模组22所分别包括的器件)相互独立的封闭在两个隔爆腔体内,而将不会产生电火花的机械传动结构(即上述的传动组件80等)、线缆70等排除在隔爆腔体外部,这样,相较将摄像机全部的器件均放置在隔爆腔体内的方案,本实施例两个隔爆腔体的整体体积较小,大大减轻了防爆摄像机的重量,在实现防爆摄像机基本功能的前提下,满足了防爆摄像机的轻量化要求。
本申请实施例提供了一种防爆摄像机,该防爆摄像机包括第一壳体10和第二壳体20,两个壳体分别具有第一隔爆腔体31和第二隔爆腔体32,第一隔爆腔体31用于安装主控模组,第二隔爆腔体32用于安装镜头模组22;其中,沿第一方向,第一壳体10的两端分别设有第一隔爆通孔11和第二隔爆通孔12,第一隔爆通孔11安装有传动轴13;第二壳体20的两端分别延伸有第一转接轴21,第二壳体20的一对第一转接轴21通过第一壳体10的一对安装耳14可转动地安装于第一壳体10;然后,一方面,第一壳体10内部(即第一隔爆腔体31内)的第一电机51通过传动轴13和外部的传动组件80即可驱动第二壳体20转动;另一方面,第一壳体10内部的主控模组伸出的线缆70依次穿过第二隔爆通孔12和同侧的一个第一转接轴21即可连接至第二壳体20内部(即第二隔爆腔体32内)的镜头模组22。
换言之,针对防爆摄像机较笨重的问题,本实施例通过相互独立的两个隔爆腔体分别封闭主控模组和镜头模组22,然后,将不会产生电火花的传动组件80和线缆70设置在两个隔爆腔体的外部,由于隔爆腔体只需封闭主控模组和镜头模组22,而将传动组件80和线缆70排除在隔爆腔体的外部,这样,相较将防爆摄像机的全部部件均设置的隔爆腔体内,减小了隔爆腔体的体积,即可大大减轻防爆摄像机的重量,满足防爆摄像机轻量化的要求,解决了现有防爆摄像机由于比较笨重无法满足轻量化要求的技术问题。
关于上述传动组件80和线缆70的封装,一种可能实施方式中,一对安装耳14分别自第一隔爆通孔11和第二隔爆通孔12延伸,第一壳体10包括一对侧盖15,侧盖15用于封盖安装耳14,以使一对侧盖15与一对安装耳14分别对接安装形成第一非隔爆腔体41、第二非隔爆腔体42;其中,第一非隔爆腔体41用于容纳同侧的传动轴13、第一转接轴21和传动组件80,第二非隔爆腔体42用于容纳同侧的第二隔爆通孔12、第一转接轴21和线缆70。
请结合图5,即,防爆摄像机两侧的传动组件80和线缆70可分别通过非隔爆腔体封闭。
其中,一对安装耳14可分别自第一壳体10的两个隔爆通孔所在的区域延伸,然后,该安装耳14中设置有容纳腔,并与同侧的隔爆通孔连通,安装耳14可通过侧盖15封闭,能够理解,这样,一对侧盖15与一对安装耳14分别对接安装即可形成第一非隔爆腔体41和第二非隔爆腔体42;其中,对于第一非隔爆腔体41而言,其应将第一壳体10的传动轴13、传动组件80和第二壳体20的一个第一转接轴21封闭,对于第二非隔爆腔体42而言,其应将第一壳体10的第二隔爆通孔12、线缆70和第二壳体20的另一个第一转接轴21封闭。
可以看到,一方面,由于防爆摄像机一侧传动轴13、传动组件80和其中一个第一转接轴21之间为机械传动连接,其不会产生电火花,另一方面,防爆摄像机另一侧连接第二隔爆通孔12和另一个第一转接轴21的线缆70也不会产生电火花,因此,上述两侧使用非隔爆腔体封闭即可,虽然仍使用了非隔爆腔体,但是相较使用隔爆腔体封闭,仍然会减轻防爆摄像机的整体重量,有利于满足轻量化要求。
在一具体实施方式中,安装耳14的端部开设有用于供第一转接轴21穿过的转接通孔141,第一转接轴21通过轴套组件142可转动地安装于安装耳14。
即,参看图7,可在安装耳14的端部开设转接通孔141,安装耳14在转
接通孔141处安装有轴套组件142,这样,一对第一转接轴21即可分别可转动地安装于一对安装耳14。
在一具体实施方式中,与线缆70同侧的第一转接轴21呈中空设置,线缆70通过填料函71插接安装于同侧的第一转接轴21。其中,填料函71用硅酮胶胶封隔爆,并在填料函71侧壁设计有止口隔爆面,端面设计有密封槽,通过压紧螺母锁紧到轴套组件142,该填料函71与轴套组件142通过O型圈密封,能够满足IPX8防水性能;
为方便实施,线缆70一侧的第一转接轴21可设置为中空结构,这样,线缆70即可伸入第二壳体20内部的第二隔爆腔体32;其中,为满足防爆要求,线缆70可通过填料函71插接于第一转接轴21。
关于上述传动组件80的结构,一种可能实施方式中,该传动组件80包括第一传动齿轮81、第二传动齿轮82和传动构件;其中,第一传动齿轮81固定安装于传动轴13通过第一隔爆通孔11伸出第一隔爆腔体31的端部,第二传动齿轮82固定于第一转接轴21的端部,传动构件用于分别与第一传动齿轮81和第二传动齿轮82传动连接,以使第一传动齿轮81通过传动构件驱动第二传动齿轮82转动。
即,可将第一传动齿轮81插接在传动轴13通过第一隔爆通孔11伸出第一隔爆腔体31的端部,然后,将第二传动齿轮82插接在同侧的第一转接轴21的端部,第一传动齿轮81与第二传动齿轮82之间再设置传动构件,这样,第一传动齿轮81通过传动构件即可驱动第二传动齿轮82转动,也就是驱动第二壳体20转动。
应理解的,为方便传动,上述第一传动齿轮81与第二传动齿轮82例如可位于垂直于第一方向的同一平面内。
在一具体实施方式中,该传动构件包括传动皮带、传动齿轮中的任一种。
即,能够理解,关于第一传动齿轮81与第二传动齿轮82之间的传动,可通过传动皮带或者传动齿轮实现,本实施例对此并不做限制。
在一具体实施方式中,该传动构件包括第一传动皮带83;其中,第一传动齿轮81与第二传动齿轮82半径相等并且传动比为1;该传动组件80还包括连杆84,连杆84的长度与第一传动齿轮81的中心到第二传动齿轮82中心的长度一致,并且,连杆84的两端分别固定于第一传动齿轮81、第二传动齿轮82表面的偏心位置。
本实施例具体使用传动皮带在第一传动齿轮81与第二传动齿轮82之间传动,相较使用传动齿轮进行传动,传动皮带的重量较轻,可尽量较少的增
加防爆摄像机的重量。
此外,考虑到第一传动皮带83与两个传动齿轮之间可能发生的跳齿现象,本实施例还在两个传动齿轮之间设置连杆84,能够理解,这就要求一方面两个传动齿轮的半径相等并且传动比为1,另一方面,连杆84的两端应分别固定在两个传动齿轮表面的偏心位置,这样,连杆84的作用在于对两个传动齿轮的转动进行限位,使其保持转动的一致性。
当然,在其它实施方式中,当使用传动齿轮在第一传动齿轮81与第二传动齿轮82之间传动时,由于传动齿轮之间不易跳齿,此时可无需设置连杆84。
在一具体实施方式中,传动组件80还包括张紧机构,张紧机构包括设于第一传动皮带83两侧的一对固定钣金85,固定钣金85上安装有张紧轮86。
针对第一传动皮带83可能发生的老化变松的现象,本实施例还可在第一传动皮带83旁设置张紧机构,请参看图8和图13,张紧机构包括一对固定钣金85,固定钣金85例如可固定在安装耳14的固定座88上,然后,固定钣金85上安装张紧轮86,张紧轮86的轴向沿第一方向设置(也即,张紧轮86的轴心与第一传动齿轮81的轴心、第二传动齿轮82的轴心平行),两个固定钣金85之间可通过弹簧87连接,这样,可首先使用螺钉等先将固定钣金85预紧固于固定座88,然后,安装第一传动皮带83后,通过调整一对固定钣金85的相对位置以将第一传动皮带83张紧后,再将螺钉拧紧即可。
关于上述第一电机51的安装,一种可能实施方式中,参见图9,第一电机51通过电机安装板52固定安装于第一隔爆腔体31,电机安装板52垂直于第一方向X设置;其中,第一隔爆腔体31在电机安装板52旁设有减速齿轮53,第一电机51的电机轴与减速齿轮53传动连接,并且,传动轴13伸入第一隔爆腔体31的端部固定插接于减速齿轮53;电机安装板52固定安装有第一光电检测模块54,第一光电检测模块54用于检测减速齿轮53的转动。
具体而言,上述的第一电机51可通过垂直于第一方向设置的电机安装板52固定安装,第一电机51安装在电机安装板52上后,第一电机51的电机轴例如沿第一方向设置;然后,该第一隔爆腔体31内还在电机安装板52旁固定有减速齿轮53,减速齿轮53的转轴沿第一方向设置;从而,一方面,第一电机51的电机轴可与减速齿轮53传动连接,另一方面,上述的传动轴13伸入第一隔爆腔体31的端部可直接固定插接于该减速齿轮53,这样,第一电机51通过减速齿轮53驱动传动轴13转动。
在其他可能的实施方式中,该第一电机51也可以垂直于水平方向安装于电机安装板52上,此时,该第一电机51的电机轴垂直与水平方向,可以在
该第一电机51与传动轴13之间设置锥齿轮来改变动力传输方向,从而将电机输出的动力传输到传动轴13上,这也是可以的。
为了对转动进行检测和校正,该电机安装板52上还可设置第一光电检测模块54,第一光电检测模块54可检测减速齿轮53的转动,譬如说,第一光电检测模块54可为红外传感器,减速齿轮53的圆周方向设置检测凸块,红外传感器通过对检测凸块的检测即可知晓减速齿轮53转动一圈,从而对转动进行校正。
能够理解,上述的第一方向X例如可为一水平方向,第一电机51驱动第二壳体20以第一方向为转轴方向自转,也就是实现镜头模组22的俯仰调整,为进一步实现镜头模组22的水平转动,一种可能实施方式中,该安装耳14沿第二方向Y延伸,以使第一壳体10与第二壳体20沿第二方向Y呈上下布置,第二方向Y垂直于第一方向X;其中,如图7所示,第一壳体10包括第一机身16和安装顶盖17,第一机身16具有第一隔爆腔体31,安装顶盖17与第一机身16以第二方向Y为转轴方向相对转动地连接,并且,安装顶盖17和第二壳体20分设于第一机身16相对的两端。
本实施例中,该第二方向例如为竖直方向,第一壳体10的安装耳14沿竖直方向向下延伸,即第二壳体20位于第一壳体10的竖直下端。该第二壳体20部分的位于第一壳体10的安装耳14之间。
其中,该第一壳体10包括第一机身16和安装顶盖17,参看图5和图6,第一机身16例如为竖直放置的柱状,第一机身16的内部即形成上述的第一隔爆腔体31,安装顶盖17位于第一机身16的上端,并且,该安装顶盖17与第一机身16以第二方向Y(即竖直方向)为转轴方向相对转动地连接;能够理解,此时,防爆摄像机通过安装顶盖17固定安装后,第一机身16相对安装顶盖17转动即可实现下方镜头模组22的水平转动。
其中,能够理解,上述安装顶盖17与第一机身16相对转动地连接应满足防爆结构的要求。
在一具体实施方式中,参见图6,该安装顶盖17设有伸入第一隔爆腔体31的第二转接轴171,第二转接轴171沿第二方向Y延伸;其中,第一隔爆腔体31内安装有第二电机61,第二电机61与第二转接轴171的端部传动连接,以使第二电机61用于驱动第一机身16以第二方向Y为转轴方向相对安装顶盖17转动。
本实施例给出了驱动第一机身16转动的一种具体结构。
即,第一机身16的顶端例如可设置第三隔爆通孔,然后,安装顶盖17
的第二转接轴171通过第三隔爆通孔伸入第一机身16内部,也就是伸入第一隔爆腔体31内,然后,第一机身16的内部固定安装有第二电机61,第二电机61与第二转接轴171的端部传动连接。
能够理解,此时,相对于第一机身16和固定于第一机身16的第二电机61而言,第二电机61即可驱动安装顶盖17相对第一机身16以竖直方向为转轴方向转动;而实际使用时,由于安装顶盖17是固定安装在防爆摄像机的安装位的,此时,第二电机61即可驱动第一机身16相对安装顶盖17转动,也就是在第二电机61的驱动下,第一机身16和第二电机61一起以竖直方向为转轴方向相对安装顶盖17转动,从而,第一机身16会带动下方的第二壳体20以竖直方向为转轴方向转动,实现镜头模组22的水平转动。
在一具体实施方式中,该第二转接轴171的端部固定安装有第三传动齿轮62,第二电机61的电机轴与第三传动齿轮62传动连接。
其中,第二电机61固定安装于第一机身16的内部,第二电机16的电机轴例如沿竖直方向设置,然后,在第二转接轴171的端部固定安装第三传动齿轮62,这样,第二电机61的电机轴即可方便地与第三传动齿轮62传动连接,也即是与第二转接轴171传动连接。
具体而言,第二电机61的电机轴与第三传动齿轮62之间例如可通过第二传动皮带63传动连接。
在一些可能的实现方式中,该第二电机61也可沿水平方向设置,也即,沿水平方向设置,此时,该第二电机61的电机轴与第二转接轴171之间可以通过锥齿轮俩传动连接,这也是可以的。
在一具体实施方式中,参见图6,该主控模组包括主控电源板91,主控电源板91固定安装于第三传动齿轮62的表面,并且,第二转接轴171呈中空设置,以使电源线500从外部穿过第二转接轴171并连接至主控电源板91。
本实施例利用第二转接轴171不会转动的特征,可将第二转接轴171设置为中空结构,然后,可在第二转接轴171端部的第三传动齿轮62的表面固定安装主控电源板91,这样,能够理解,电源线500可从外部穿过中空的第二转接轴171以及第三传动齿轮62连接至主控电源板91,以为防爆摄像机供电。
也就是说,在第二电机61的驱动下,第一机身16会相对安装顶盖17转动,而安装顶盖17、第二转接轴171、第三传动齿轮62以及主控电源板91并不转动。
在一具体实施方式中,参见图6,该主控模组还包括器件安装座92,器
件安装座92固定安装于第一隔爆腔体31的内部;其中,沿第二方向Y,器件安装座92在主控电源板91的投影区域设有可转动地滑环93,滑环93与第二转接轴171共轴设置,以使主控电源板91通过滑环93与安装于器件安装座92的机身器件电连接。
即,结合上面的描述,主控电源板91与第一机身16会发生相对转动,此时,为了实现主控电源板91与第一机身16内部其它机身器件的电连接,可在第一机身16内部固定安装器件安装座92,器件安装座92在主控电源板91的投影区域设有可转动的滑环93,即,滑环93以竖直方向为转轴方向可转动地安装于器件安装座92,并且,该滑环93应与第二转接轴171共轴设置,这样,能够理解,在第一机身16相对主控电源板91转动时,器件安装座92会跟随第一机身16一起转动,而滑环93由于可相对器件安装座92转动,此时滑环93可实现与主控电源板91的电插接而不转动。
此外,与上述第一光电检测模块54类似的,该第一机身16内部还可固定安装第二光电检测模块,用于检测第一机身16的转动;譬如说,参见图9,第二光电检测模块可通过水平光电板64固定安装于第一机身16,第二光电检测模块可为红外传感器,第二转接轴171或第三传动齿轮62的圆周方向设置检测凸块,红外传感器通过对检测凸块的检测即可知晓第一机身16转动一圈,从而对转动进行校正。
需要说明的是,参见图9,该第一机身16的顶端例如可为封闭设置,然后底端(即朝向第二壳体20的一端)为开口设置,开口可通过第一端盖18封闭。
一种可能实施方式中,参见图10和图11,第二壳体20包括第二机身23和第二端盖24,第二端盖24封闭第二机身23以形成第二隔爆腔体32;其中,第二端盖24开设有镜头视窗26,镜头模组22安装于第二机身23内部并旁设于镜头视窗26。
即,第二壳体20的前端例如可为开口设置,然后该开口通过第二端盖24封闭,这样,第二壳体20内部形成第二隔爆腔体32。
其中,该第二端盖24上可设置镜头视窗26,镜头模组22安装在第二机身23内部并旁设于镜头视窗26。这样,该镜头模组22可以采集透过镜头视窗26的光线。
在其它实施方式中,参见图4和图10,该第二端盖24还可设有雨刷模块100、麦克风模块200和补光模块300,以提升功能性。
此外,第二壳体20还包括第三端盖25,第三端盖25封闭第二机身23以
形成容置腔43,该容置腔43与第二隔爆腔体32连通,容置腔43可用于容置喇叭模块400。其中,该第二端盖24和第三端盖25分别封闭该第二机身23表面的不同位置,以分别形成第二隔爆腔体32和置腔43。
