[0036] It should be noted that, when the digestion tube is removed from the water holding cavity, a small amount of pure water will be taken away. In order to ensure stable cooling effect for a long time, the pure water in the water holding cavity needs to be replenished regularly.

[0037] In an embodiment, the heat exchange assembly 1 includes a hollow shell 11, the bottom of the shell 11 is provided with a drain pipe 12 communicating with the inside of the shell 11, the top of the shell 11 is provided with a heat exchange piece 13 inserted into the shell 11 and movable up and down, and the area between the shell 11 and the heat exchange piece 13 is the heat exchange chamber;
