Induction charging apparatus

An induction charging apparatus having a power source unit and a device unit detachable from said power source unit, said induction charging apparatus comprising:

• said power source unit comprising:
• a first casing having one end opened;
• a primary coil provided in said first casing;
• oscillator means provided in said first casing for supplying an alternating current powered by a commercial alternating current power source to said primary coil to generate magnetic fluxes;
• and
• a depressible member movably provided and closing said open end of said first casing, said depressible member movable between a lift position at which said magnetic fluxes are substantially located under said depressible member and inside said first casing, and a depressed position at which portions of said magnetic fluxes are substantially located over said depressible member and outside said first casing;
• said device unit comprising:
• a second casing having one end detachable to said open end of said first casing;
• a secondary coil provided in said second casing and adjacent to said one end;
• and
• load means provided in said second casing for receiving power from said secondary coil, whereby when said second casing is attached to said first casing with said depressible member being moved to said depressed position, said primary and secondary coils are coupled to link said magnetic fluxes from said primary coil to said secondary coil, and when said second casing is detached, said depressible member is moved to said lift position to prevent the leakage of said magnetic fluxes.
