[0029] Among them, the first float 209 and the second float 210 can move freely up and down along the middle hollow rod 208, and the first float 209 and the second float 210 are separately provided with two upper and lower sections of retaining springs to limit the movement space of the first float 209 and the second float 210.

As the electrolysis continues, the electrolyte level gradually decreases. When the liquid level reaches the low level, the second float 210 descends to trigger the low liquid level switch and output a low liquid level signal.
