Abstract
A shaver (10) includes a razor blade (20a, 20b) that cuts hairs coming into contact therewith. A heating element (26a, 26b) is bonded to the razor blade (20a, 20b). The heating element (26a, 26b) generates heat when an electric current is passed therethrough, the generated heat being directly supplied to the razor blade (20a, 20b). A battery (32) generates electric current, and electrical conductors (28, 30, 50, 52) route electric current generated by the battery (32) to the heating element (26a, 26b). A handle (16) is adapted to be held by a user for manipulation of the shaver (10). Suitably, the handle (16) houses the battery (32), and a head (12) houses the razor blade (20a, 20b) and heating element (26a, 26b) bonded thereto, the head (12) being selectively attachable to and detachable from the handle (16).
Claims16
A shaving device comprising:
- a handle by which a user manipulates the shaving device;
- a razor blade;
- a heating element bonded to the razor blade, said heating element generating heat in response to electric power being supplied thereto;
- a head detachably connected to the handle, said head containing the razor blade;
- electric supply means for selectively supplying electric power to the heating element, wherein said electric supply means is housed in the handle;
- a first pair of electrical contacts arranged in the head in electrical communication with the heating element;
- and,
- a second pair of electrical contacts arranged in the handle in electrical communication with the electric supply means, said second pair of electrical contacts engaging with said first pair of electrical contacts when the head is attached to the handle to provide an electrical connection between the electric supply means and the heating element.
A shaving device comprising:
- cutting means for cutting hairs coming into contact therewith, said cutting means comprising a razor blade;
- heating means for supplying heat to the cutting means when energized, said heating means comprising a resistive heating element bonded to the razor blade, said resistive heating element generating heat in response to an electric current passing therethrough;
- a handle by which a user manipulates the shaving device;
- generating means for generating electric power that is supplied to the heating means thereby energizing the same, said generating means being housed in the handle;
- a head which is selectively attachable to and detachable from the handle, said head housing the cutting means and the heating means;
- and,
- power transfer means for transferring power generated by the generating means from the handle to the head when the head is attached to the handle.
A shaver comprising:
- a razor blade that cuts hairs coming into contact therewith;
- a heating element bonded to the razor blade, said heating element generating heat when an electric current is passed therethrough, said heat being supplied to the razor blade;
- a battery that generates electric current;
- electrical conductors through which electric current generated by the battery is routed to the heating element;
- a handle adapted to be held by a user for manipulation of the shaver, said handle housing the battery;
- and,
- a head that houses the razor blade and the heating element bonded thereto, said head being selectively attachable to and detachable from the handle.
A shaving device comprising:
- a moving blade;
- drive means for driving the moving blade;
- an infrared heat source which selectively radiates infrared heat upon the cutting means;
- and,
- blade support means upon which the moving blade is supported, said blade support means carrying the infrared heat source.
