The cathode protection principle of electrochemical corrosion prevention sacrificial anode of metal in water is utilized by adopting a stainless steel type or manganese steel metal inner container, a magnesium rod is used as an anode, and the metal inner container is used as a cathode. In the water heater, a magnesium rod is arranged in the middle of a metal inner container. Under the condition that the enamel coating on the surface of the metal inner container is complete, the metal inner container is shielded by the enamel, the insulation resistance between the magnesium rod and the metal inner container can reach more than 2 MOmega, and the output current of the magnesium (rod) anode is almost zero. When the enamel inner container has cracks locally, a small resistance is formed between the magnesium anode and the metal inner container through water, the magnesium anode starts to output current and flows to the exposed metal inner container to generate a polarization film, and the damaged enamel is repaired, so that the gold inner container is insulated and prevented from being corroded. The magnesium anode is called sacrificial anode method because it consumes itself when outputting current
However, the magnesium rod used in the current electric water heater is usually connected to the mounting seat and fixed at the drain hole of the electric water heater by adopting a magnesium rod, and because the magnesium rod and the fixing seat are integrated, when the magnesium rod needs to be replaced when the service life of the magnesium rod is up, the fixing seat needs to be replaced together with the magnesium rod, so that the cost of the fixing seat is increased.
