Solar-Powered Copper Ion Generator, and Polarity Reversal Method and Electrode Depletion Determination Method Thereof

A solar-powered copper ion generator, comprising a main body (1) and an electrode assembly (2) mounted on the main body (1), wherein a dirt collection assembly (3) is detachably mounted on an outer side of the electrode assembly (2), the dirt collection assembly (3) comprising a filter basket (31) covering the outer side of the electrode assembly (2) and a dirt collection box (32) detachably mounted at a bottom of the filter basket (31), a drainage through hole (321) in communication with the filter basket (31) is provided in the dirt collection box (32), and the bottom of the filter basket (31) is provided with an inlet (341);

• a float (33) is liftably mounted in the filter basket (31), and the float (33) is located right above the drainage through hole (321) and is capable of opening and closing the inlet (341);
• and when in use, the float (33) rises to open the inlet (341), and dirt generated by the electrode assembly (2) falls along an outer ring of the float (33) and is collected in the dirt collection box (32) through the inlet (341).
