具体实施方式
为了更清楚地说明本实用新型，下面结合优选实施例对本实用新型做进一步的说明。本领域技术人员应当理解，下面所具体描述的内容是说明性的而非限制性的，不应以此限制本实用新型的保护范围。
在本实用新型的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“前”、“后”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制。
在本实用新型的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“设置”应做广义理解，例如，可以是固定相连、设置，也可以是可拆卸连接、设置，或一体地连接、设置。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1至2所示，一种用于配电箱内的自动灭火装置包括：干粉 仓1、喷射装置2、光敏电阻3、进气装置4、电源5和固定连接件6；所述干粉仓1的数量为两个，相对设置于配电箱的内部两侧壁上，并通过固定连接件6连接；所述固定连接件6为双面胶。干粉仓1为一种呈长方体形的盒装结构，其尺寸可根据配电箱尺寸进行相应的放大或者缩小，为了便于安装，本申请通过在干粉仓的背面设置双面胶，用于连接配电箱的内侧壁，相对设置能够使干粉仓内的干粉充分的覆盖配电箱内的电器元件，提高安全性。
显而易见的是，固定连接件采用双面胶是本申请所选取的成本低廉的一种作业方式，其还可以替换为市场上较为常见的连接方式，如建筑用胶水等。
进一步地，所述光敏电阻3的数量为若干个，并设置于配电箱的内壁上，若干个所述光敏电阻3之间相互并联，并与两侧所述干粉仓1电连接；所述光敏电阻3至少为五个，且分别设置于配电箱内的各个侧壁上；光敏电阻3同样通过双面胶连接，贴合在配电箱的左右两侧壁、上下侧壁和后壁上，其目的在于，使光敏电阻3尽量的覆盖于配电箱内电器元件的各个方向，能够准确地感知配电箱内火花；
可以理解的是，通过简单电路将几个光敏电阻连接成并联电路，并接通两侧干粉仓的电源，是一种较为基础的电路，中学所学的电路知识就可以满足上述操作。
进一步地，所述干粉仓1的内部从上至下依次设置为喷射室101、电源室102、储粉室103和进气室104；所述喷射装置2设置于所述喷射室101内，且所述喷射装置2通过软管连接于储粉室103；所述 电源5设置于所述电源室102内，并与所述喷射装置2和进气装置4电连接；所述进气装置4设置于所述进气室104内。
进一步地，所述喷射装置2为抽风机。抽风机采用现有技术中现售的一款微型抽风机，其功率较小，但可以满足于从储粉室内吸取干粉，并喷射出去。
进一步地，所述进气装置4包括吹风机401、单向气阀402和进气管403；所述吹风机401固设于底部进气室内；所述吹风机401的出气端口连接有单向气阀402，并使单向气阀402插入于储粉室103；所述吹风机401的进气端口连接有进气管403；所述进气管403的另一端穿过所述干粉仓1的底部仓壁。
进一步地，所述电源5为锂电池组。
本装置的工作原理：
五个光敏电阻设置于配电箱的各个侧壁上，并通过电线连接两侧干粉仓的电源、喷射装置和进气装置，当光线较弱时，光敏电阻相当于断路状态，当配电箱内线路发出火花时，强光会使光敏电阻的电阻值降低，使得整个电路处于通路状态，两侧喷射装置和进气装置开始运行，从储粉室内抽出干粉，喷向电器元件，进而达到灭火的目的，当火花或者火苗被扑灭时候，光敏电阻的电阻值重新变成无限大，相当于断路，使喷射装置和进气装置停止运行。
显然，本实用新型的上述实施例仅仅是为清楚地说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定，对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形 式的变化或变动，这里无法对所有的实施方式予以穷举，凡是属于本实用新型的技术方案所引伸出的显而易见的变化或变动仍处于本实用新型的保护范围之列。
