When the distillation is completed, due to the existence of the overflow weir 22, a certain amount of liquid will remain in the circular groove 21. At this time, the floating plate 10 will sink with the liquid level, and the plugging plate 12 will be pushed down by the connecting rod 13, so as to open the leakage hole 11. The liquid in the circular groove 21 will slowly flow out from the leakage hole 11 and flow into the drainage channel below.
