Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a water purification component and an electric water heater. Background Art

[0002] At present, there are many electric water heaters with water purification or filtering functions on the market. Considering that the solution of external water purification device often makes the pipe connection complicated, it increases the risk of water leakage in the pipe connection, and the cost is also relatively high. Therefore, from the perspective of reducing production costs and simplifying design, electric water heaters with built-in water purification devices have appeared in the industry. Among them, the Chinese utility model patent with application number CN202021142187.6 provides a structural scheme for fixing the water purification module in the position of the magnesium rod. In this scheme, the water purification module is provided with a through hole at the axis, which is installed in series on the magnesium rod fixing rod. As a result, each time the water purification module is disassembled or replaced, the magnesium rod fixing rod must be unscrewed from the drain plug before the water purification module can be removed, which is extremely inconvenient for after-sales work. Even when rust occurs at the threaded connection between the magnesium rod fixing rod and the drain plug, the water purification module will not be able to be replaced separately. The water purification module can only be replaced together with the drain plug and the magnesium rod fixing rod, which is costly.
