The improvement of the present invention also lies in how to stabilize the specific structural improvement of the electrolytic cell involved in the formation of hypochlorous acid water:

1. The cooling structure of the electrolytic cell for cooling the electrolytic sheet.

Referring to FIG. 2 and FIG. 3, FIG. 3 is a schematic diagram of a cooling structure of an electrolysis system for preparing hypochlorous acid water according to the present invention; an inner space for accommodating a hydrochloric acid electrolyte is formed in a middle portion of the inner tank 11.

The water inlet hole 121 and the water outlet hole 122 communicate with the external space in the outlet hole 122 of the hypochlorous acid water (HClO).

In the electrolysis process, a high current generates heat through the electrolytic sheet, so that the temperature of the electrolytic sheet rises, the impedance increases, the current flow rate decreases, and the amount of chlorine gas is generated. With the above structure, tap water is introduced from the water inlet hole 121 of the outer tank 12 to the outside. In the space, since the tap water is introduced to the outer periphery of the inner tank 11, the electrolytic sheet in the inner tank 11 can be effectively cooled, the impedance of the electrolytic sheet can be lowered, and the amount of chlorine gas generated can be prevented from being affected.

A flow hole 231 of 2 to 4 mm is opened below the central electrolytic sheet 23. During the electrolysis process, the pumping speed of the electrolyte should not be too fast, and the electrolyte will enter the B zone 14 from the A zone 13 and then convect the B zone 14 to the C zone 15 if the electrolyte enters the B zone 14 with insufficient capacity or pores. When it is blocked, the electrolyte will enter the C zone 15 from the A zone 13 and then convect to the B zone 14 through the flow hole 231. The flow control of the electrolyte is more convenient, and the electrolyte in the inner tank is prevented from being more than the budget. To make hypochlorous acid water more stable.
