When adding water during use, the water tank needs to be pulled out and water needs to be added from the upper opening of the water tank with a container, which increases the workload of laboratory personnel. And because there is no automatic water adding function, the instrument is prone to water shortage warning during use. For example, the patent with announcement number CN 209049391U announced on July 2, 2019, the water tank of the constant temperature and humidity chamber involved has no external water source inlet pipe and automatic water adding device. When adding water, the chassis cover and water tank cover need to be opened. As the instrument is used, a certain amount of dirt will be generated in the water tank. There is no drainage device at the bottom of the water tank. The experimenter needs to take out the water tank and take it to the cleaning pool for cleaning. Adding water, draining and cleaning are inconvenient. Utility Model Content
