Abstract
A power supply apparatus, especially one for supply charging power to an electric toothbrush, comprises a first housing portion, a power input coupler, a second housing portion having a platform comprising platform surface which projects away from the first housing portion, and a power output coupler formed on the platform. The apparatus is configured for wall mounting so that a load can be charged while supported by a wall outlet.
Claims19
A power supply apparatus comprising a first power coupler on a first housing portion, a second power coupler inside a second housing portion, and electronic circuitry interconnecting the first power coupler and the second power coupler;
- wherein the first power coupler is a power input coupler which is configured for moving in a first direction in order to enter into physical and electrical connection with a power outlet to receive input power;
- wherein the second housing portion comprises a platform which is configured for supporting an electrical load and an internal compartment in which the second power coupler is housed, the platform having a platform surface which is parallel to the first direction and extends away from the first power coupler, the second power coupler being a power output coupler;
- wherein the electronic circuitry is configured for converting the input power into output power which is suitable for wireless transfer across the second housing portion;
- wherein the first housing portion is intermediate the second housing portion and the first power coupler;
- wherein the first power coupler is configured to cooperate with the power outlet so that the second housing is elevated in a cantilever configuration above a base surface when the power input coupler is attached to a wall-mounted power outlet;
- wherein the first housing portion comprises a front panel having a front panel surface which is adjacent the platform surface and wherein the front panel surface projects for a height above the platform surface when the apparatus is resting on a horizontal surface and with the bottom surface in abutment with the horizontal surface and supporting the weight of the apparatus;
- and
- wherein the apparatus comprises a load retention structure which protrudes orthogonally from the platform surface, and wherein the load retention structure is oppositely facing the front panel surface.
An electric toothbrush power supply apparatus comprising a main housing having a first power coupler on a first housing portion, a second power coupler inside a second housing portion, and electronic circuitry interconnecting the first power coupler and the second power coupler;
- wherein the first power coupler is a power input coupler which is configured for moving in a first direction in order to enter into physical and electrical connection with a power outlet to receive input power;
- wherein the second housing portion comprises a platform which is configured for supporting an electrical load in the form of an electric toothbrush and an internal compartment in which the second power coupler is housed, the platform having a platform surface which is parallel to the first direction and extends away from the first power coupler, the second power coupler being a power output coupler;
- wherein the electronic circuitry is configured for converting the input power into output power which is suitable for wireless transfer across the second housing portion;
- wherein the first housing portion and the second housing portion are integrally joined and the main housing is configured to be water-proof, and the first housing portion is intermediate the second housing portion and the first power coupler,
- wherein the first power coupler is configured to cooperate with the power outlet so that the second housing is elevated in a cantilever configuration above a base surface when the power input coupler is attached to a wall-mounted power outlet,
- wherein the first power coupler is configured to approach the power outlet in the first direction and the platform surface extends in a second direction to project away from the first housing portion, the second direction being opposite to the first direction;
- and
- wherein the first housing portion extends in a third direction which is orthogonal to the first direction and the second direction to form a partition between the power output coupler and the power input coupler, the partition projecting beyond the platform surface to define a splash guard between the power output coupler and the power input coupler configured to mitigate splashes of conductive liquid into the power outlet, the height of the partition being twice the axial height of the power output coupler.
