Abstract
Water-tight battery powered appliances, for example personal care appliances such as razors and toothbrushes, are provided. The appliances include a housing having a seal that allows gases, e.g., hydrogen, to vent from the appliance without allowing water to enter.
Claims20
A water-tight, battery powered appliance comprising:
- a housing, having an outer surface, a generally hollow interior and an aperture through which gas can be vented from the interior;
- a seal, positioned to normally cover the aperture, the seal being configured to flex in response to pressure within the hollow interior and move away from the aperture when a predetermined pressure is exceeded;
- and an actuator exposed at the outer surface of the housing wherein the actuator extends from the aperture.
A water-tight, battery powered appliance comprising:
- a housing, having an outer surface, a generally hollow interior and an aperture through which gas can be vented from the interior;
- a seal, positioned to normally cover the aperture, the seal being configured to flex in response to pressure within the hollow interior and move away from the aperture when a pressure between about 0.1 bar and 2 bar is exceeded;
- and
- an actuator having a stem extending from the aperture, wherein the seal surrounds the stem portion of the actuator.
