The first cover assembly (corresponding to 110a and 110 b) and the second cover assembly (corresponding to 111a and 111 b) are detachably disposed in the openings at the front and rear ends of the housing 101.

As shown in fig. 4 to 10, the storage tank 102 has a hollow structure, and an opening structure is formed at an upper end thereof for storing purified water/water to be electrolyzed.

Wherein, a square cover 108 is disposed on the open side of the water storage tank 102, and is used for covering the opening of the water storage tank 102, so that the water storage tank 102 forms a relatively sealed structure.

Further, the first filter element assembly 103 and the second filter element assembly 104 are cylindrical structures, and are used for filtering/adsorbing impurity ions (such as potassium ions, sodium ions or calcium ions) of the water body so as to maintain the TDS value of the water body within a normal range (0-9).

Specifically, the first filter element assembly 103 is axially disposed at the lower end within the water storage tank 102, and is used for adsorbing impurity ions of the water body within the water storage tank 102 so as to maintain the TDS value of the water body within a normal range (0-9).

It can be understood that the second filter element assembly 104 is arranged at the upper end of the water return port 102d of the water storage tank 102, namely, part of the water body which flows back after the electrolysis of the electrolytic tank 105 is led in through the water return port 102d, and after the second filter element assembly 104 is subjected to filtering treatment, the water body is filtered and treated through the first filter element assembly 103, so that the water body circulation is formed in the water storage tank 102, the reliability of the water body filtration is further improved, impurities in the circulating water body in the water storage tank 102 are reduced, the TDS value of the purified water can be maintained within a normal range (0-9), the working time of the water body in the water storage tank 102 is further prolonged, and the reliability that the operation of the electrolytic tank 105 can be maintained only by frequently increasing or replacing the purified water is avoided.
