The flow rate sensor and the third check valve are convenient for sensing the flow rate and preventing backflow, and the electric control valve is convenient for controlling the amount entering the electrolytic cell.

[0010] Furthermore, the first bearing support frame, the second bearing support frame, the rotating shaft and the mixing blades are provided in plurality, so as to facilitate the sufficient mixing operation.

[0011] Furthermore, the second water conduit is connected to a mixing box, the top of the mixing box is connected to a stirring motor, and the bottom power end of the stirring motor is connected to an agitator extending into the mixing box, so as to facilitate further auxiliary mixing operations.
