Specifically, the battery 130 and the working circuit 140 are disposed in the first space S1, and the water electrolysis circuit 150 is disposed in the second space S2. The water electrolysis circuit 150 includes a solid electrolyte 152, a first wire 154, and a second wire 156. The solid electrolyte 152 is disposed in the second space S2, and is disposed, for example, around the first space S1 and along a joint between the first cover 110 and the second cover 120. Since the solid electrolyte 152 is disposed at the joint between the first cover 110 and the second cover 120, and is blocked in the electron The external space of the device 100 is between the first space S1 provided with the internal circuit, so that when the electronic device 100 is flooded, the solid electrolyte 152 can prevent the water from directly penetrating into the first space S1 and damaging the battery 130 and/or the working circuit 140.

Referring to FIG. 4 and FIG. 5, in the embodiment, the first wire 154 located in the second space S2 is located between the first cover 110 and the solid electrolyte 152, for example, and the second wire 156 is located, for example, in the second. The lid body 120 is interposed between the lid body 120 and the solid electrolyte 152, but the invention is not limited thereto. In another embodiment, the second wire 156 can be positioned between the first cover 110 and the solid electrolyte 152, and the first wire 154 is positioned between the second cover 120 and the solid electrolyte 152. In still another embodiment, the first wire 154 and the second wire 156 located in the second space S2 may also be located between the first cover 110 and the solid electrolyte 152, respectively.
