ABSTRACT:
A self-contained electric shaver capable of being used with water and powered from either a main or a reserve rechargeable battery comprises a housing having thereon a shaving head and accommodating therein the main and reserve rechargeable batteries. The housing also accommodates a motor drivingly connected to the shaving head for effecting a hair shearing operation. Terminal pins adapted to be connected to an external battery charger for feeding an electric charging current to the batteries extend in a sealed manner through respective apertures formed in the lower end wall of the housing. At least one drain pipe extends in a sealed manner through a vent hole also formed in the lower end wall for passing out of the housing the gas discharged from the batteries upon charging thereof. The terminal pins and the drain pipe, all concentrated to the lower end wall to extend therethrough, are sealed with respect to the corresponding apertures and vent hole for preventing the outside water from entering interior of the housing while allowing the discharged gas to be drained out of the housing.
