When the electrode assembly 21 is disposed in the cavity 13 formed by the cooperation of the first and second cases 11 and 12, it is necessary to electrically discharge the electrode assembly 21 to the outside of the case 1 through the electrical connector 22. As the electrical connector 22 passes through the second housing 12, the plastic second housing 12 makes an insulated connection with the electrical connector 22,

In addition, the first recess 313 is provided with a detection part 32 electrically connected with the outside, so that after the liquid buffered in the first recess 313 reaches a certain set condition, the detection part 32 can detect the liquid in the first recess 313, so that the user can know that the electrolysis device is in a leakage state, and can process the electrolysis device according to the detection state, so as to solve the leakage problem. So that through complex fixed part 31, first sunken 313 and detection portion 32 in order to realize the weeping detection to electrolytic device, this kind of simple structure can not cause the condition of whether the leakage exists in electrolytic device in the time of the liquid overflow of leakage, practice thrift the space that can make things convenient for quick acquisition.

And the first conductor and the second conductor which are arranged on the first bottom wall extend out of the first bottom wall, and the limit of the first conductor and the second conductor in the height direction is used for avoiding the situation that the conductors are in error contact with the electric connector 22, so that the safety performance of the electrolysis device is improved.
