Abstract
Various designs of a system for charging a hand-held, hair cutting device are shown. The system includes a hair cutting device and a charging station. The hair cutting device and charging station each include an inductive charging coil. At least one of the hair cutting device and charging station include a magnet to pull or bias the hair cutting device such that the respective inductive charging coils are brought into alignment, allowing for charging of the hair cutting device.
Claims21
A system for a hand-held, hair cutting device comprising:
- a housing including:
- an upper housing;
- and
- a lower housing comprising a charging interface surface extending along a longitudinal axis of the housing;
- a battery contained within the housing and coupled to a first inductive charging coil, the first inductive charging coil being located within the housing proximate to the charging interface surface, the battery being chargeable with a charging stand including a power supply coupled to a second inductive charging coil, the second inductive charging coil being located proximate to a support surface for supporting the device, the charging stand being configured to charge the battery when the first and second charging coils are oriented in a predetermined alignment, wherein a permanent magnet is fixed within one of the device or stand and a field device is positioned within the other of the device and stand, such that the permanent magnet and the field device interact to force the coils toward the predetermined alignment;
- a pair of blades supported by the housing;
- and
- an electrically powered drive contained within the housing and coupled to the battery such that at least one of the pair of blades moves relative to the other blade in response to electric power from the battery;
- wherein one of the permanent magnet and the field device is positioned between the electrically powered drive and the charging interface surface.
