  • Patent number: 8533958
    Abstract: In a razor having a handle and a blade cartridge containing one or more blades, a system is provided for selectively heating the blades to a controlled temperature range. The blade heating system includes an electric circuit with a battery power source for controlled direction of current flow through the blades in order to heat the blades. The electric circuit includes an automatic on/off switch, such as a proximity switch or a tilt switch with a timer for opening the circuit after an elapsed period for preserving battery life, a visual indicator for indicating on/off status, and a heat controller for selectively adjusting the temperature of the blades. With the exception of the blades, the components of the electric circuit are carried in the razor's handle and an inductive coupling is provided at the connection of the handle and blade cartridge for electrically connecting the blades to the electric circuit.
