In the case of rechargeable batteries, there is a risk that gas such as hydrogen gas may be generated from the anode due to reverse charging, overcharging, low temperature charging, continuous discharging, etc. Further, there is a similar danger with dry batteries and dry cell type rechargeable batteries, and when multiple batteries are used in series, they may be exposed to reverse charging due to voltage differences, and there is an unavoidable risk of hydrogen gas generation.

低いという問題があつた。 Therefore, in conventional waterproof battery-powered electrical equipment, gases such as hydrogen gas generated from storage batteries (dry batteries) during charging and discharging are released from the main body case, and the pressure relationship between the inside of the main body case and the outside is controlled. To maintain a constant pressure, a ventilation filter and constant pressure valve are installed. However, since it is installed separately in a part of the main body case, it leads to high cost and large size. Furthermore, regarding the explosive nature of the gas generated from the battery, there was a problem in that the explosion-proof effect was low because a gas outlet was not provided near the switch, which serves as the ignition part.

In the waterproof battery-powered electric device of the present invention, the filter is in the form of a thin plate, and the switch handle presses the internal switch contact from the outside of the filter to connect and separate the switch contact. Therefore, the filter also serves as a switch, reducing the number of parts, reducing assembly man-hours, and saving space. Moreover, since the filter is in the form of a thin plate and transmits the operation of the switch handle to the switch contacts, it can be provided over a wide area, unlike filters provided at the periphery of the opening. Therefore, a high gas release effect can be obtained and the explosion-proof effect can be improved.
