当使用时，将所述图像采集装置（例如手机）固定在所述连接装置10上，使得所述图像采集装置2的拍摄装置20对应所述第一通孔103、第二通孔314，从而使得所述拍摄装置20对应所述镜头模组52。当拍摄测试样本上的雾滴影像时，所述镜头模组52可以提供不同的放大倍数，所述灯光系统70可以提供光源，从而使得所述拍摄装置20所拍摄的雾滴影像更清晰。
可以理解的是，为了保护镜头系统50，所述第二通孔314处可以设置透明材料（例如玻璃）盖设在该第二通孔314处。
可以理解的是，在其他实施方式中，也可以是所述镜头模组52直接拍摄所述测试样本上的雾滴影像，然后通过有线或无线的方式传输至图像采集装置，此时，所述连接装置10可以省略。
可以理解的是，当所述图像采集装置2上设置有手电筒装置时，所述灯光系统70的光源71可以由所述手电筒装置代替，而所述电路板60上设置的光源71可以省略。
可以理解的是，所述雾滴测试仪1的电源系统40可以省略，而直接由图像采集装置2对所述雾滴测试仪1提供电能。
虽然上所述的实施例中所述按钮90设置在所述下壳32的底板上，可以理解的是，所述按钮90可以设置在所述壳体30的任一面板上，只要能保证与所述电路板的电性连接及便于操作即可。
图8提供本发明另一实施方式的雾滴测试仪1’中。所述雾滴测试仪1’与图1-7的雾滴测试仪1的结构大致类似。此外，所述雾滴测试仪1’省略了指示灯组件以及导光件。所述雾滴测试仪1’的光源71’设置于镜筒52’朝向下壳32’的一侧，所述光源71’包括固定板711以及发光部712，所述固定板711连接于所述镜筒52’朝向所述下壳32’一端，所述发光部712位于所述固定板711朝向所述下壳32’的一侧表面，所述发光部直接朝向所述下壳32’上的通孔320’发射光线，以为雾滴的拍摄提供照明，此种光源71’的设置方式由于直接向所述通孔320’发射光线，因此可以省略导光件，并因此可以降低雾滴测试仪1’的整体重量。
所述雾滴测试仪1’包括镜头限位件54，所述镜头限位件54用于定位所述镜头模组52，本实施方式中，所述镜头限位件54大致呈环状，所述镜头限位件54上形成有第一卡合部541，所述固定板711上形成对应于所述第一卡合部541的第二卡合部711a，所述镜头限位件54通过所述第一卡合部541与所述第二卡合部711a的相互配合定位所述镜头模组52。所述镜头限位件54还可与所述下壳32’连接，以限定所述镜头组件52相对于所述下壳32’的位置。
本实施方式中，所述第一卡合部541为凸出于所述镜头限位件54的卡扣，所述第二卡合部711a为开设于所述固定板711上的卡槽，可以理解，所述第一卡合部541与所述第二卡合部711a的结构可以互换；此外，所述第二卡合部711a可以直接形成于所述镜筒52’上；进一步，所述第一卡合部541以及所述第二卡合部711a可以由其他任意合适的可以连接两个元件的连接结构替换，例如，螺纹连接结构等，不再一一详述。
本实施方式中，上壳的第二侧板316上形成有凹陷的装配槽318，所述装配槽318与电池盖402’的形状及尺寸相适配，装配时，所述电池盖402’能够收容于所述装配槽318内。所述装配槽318的底面上形成第一定位部319，所述第一定位部319能够与电池盖402’的锁固孔4020’配合定位所述电池盖402’于所述上壳上的装配位置。电池防水件403’上形成有对应于所述第一定位部309的第二定位部403a，所述第二定位部403能够与所述第一定位部相配合，使得所述电池防水件403’相对于上壳的安装位置不易松动，进一步提升防水性能。本实施方式中，所述第一定位部319以及所述第二定位部403a均为中空凸柱，所述第一定位部319内设螺纹孔，其能够与穿过所述电池盖402’的螺栓连接件相连以固定所述电池盖402’；所述第二定位部403a内设通孔，所述通孔能够使得所述第一定位部319穿过，换言之，所述第二定位部403a能够套设于所述第一定位部319上。
可以理解，在其他的实施方式，所述第一定位部319以及所述第二定位部403a可以为任意能够限定所述电池防水件403’相对于所述上壳的位置的结构，不再赘述。
另外，对于本领域的普通技术人员来说，可以根据本发明的技术构思做出其它各种相应的改变与变形，而所有这些改变与变形都应属于本发明权利要求的保护范围。
