1. A portable appliance comprising:
- a housing of said appliance that contains electrically powered apparatus, a battery for energizing said apparatus and a secondary coil of electrically-conductive winding that is coupled to translate magnetically-induced energy to said battery;
an elongated core of magnetically-permeable material disposed within said secondary coil;
a base that defines a well for supporting the portion of said housing within which said secondary coil is positioned and which includes a primary coil of electrically-conductive winding that is responsive to applied power for magnetically inducing energy into said secondary coil;
an elongated stud of magnetically-permeable material disposed within said primary coil, said stud being aligned axially with said core and having an end portion adjacent to an end portion of said core, one of said end portions being generally cup shaped and the other of said end portions being formed and relatively oriented to nest within said one end portion.

Abstract
An electric toothbrush housing contains a motor, a battery and a secondary coil coupled to charge the battery. An elongated magnetic core is disposed within that secondary coil. A well is defined in a base which receives a portion of the housing within which the secondary coil is positioned. In that base is a primary coil for inducing magnetic energy into the secondary coil. Disposed within the primary coil is an elongated stud of magnetic material. It is aligned axially with the core, so that respective end portions are mutually adjacent. One of those end portions is generally cup shaped and the other is formed and relatively oriented to nest within the first.

10. A portable appliance comprising:
-
a housing of said appliance that contains electrically powered apparatus, a batter for energizing said apparatus and a secondary coil of electrically-conductive winding that is coupled to translate magnetically-induced energy to said battery; a base that defines a well for supporting the portion of said houing within which said secondary coil is positioned and which includes a primary coil of electrically-conductive winding that is responsive to applied power for magnetically inducing energy into said secondary coil; magnetically-permeable material disposed within said primary and secondary coils for coupling magnetic flux therebetween; said base further including means defining a U-shaped cavity aligned atop said well and open through a sidewall of said base.
