The collection tray 81 is installed on the inner wall of the main body 1 of the test device. The guide tube 82 is fixedly connected to the rear side of the inner cavity of the collection tray 81. The end of the guide tube 82 is connected to the collection shell 83 installed on the side surface of the main body 1 of the test device. The surface of the collection shell 83 is provided with an observation window 84.

[0041] The water droplets generated in the main body 1 of the test device are collected by the collection tray 81 and guided into the inner cavity of the collection shell 83 through the guide pipe 82 for easy collection.
