System for regulating electric current flow from a power source to a blade cartridge in a wet shave razor

摘要

A system for regulating current flow in a wet shave razor includes one or more conductive materials, such as metals, in electric circuit connection, wherein each conductive material has unique resistance properties and is used to regulate the amount of current (i.e. heat) flowing to at least one electrically powered component on the blade cartridge, and particularly one or more electrically powered devices/elements on the blade cartridge such as, but not limited to, one or more blades, one or more heating elements, a vibration device, illuminating device (e.g. LED or bulb), gauges, or indicators. The length and thickness of the conductive materials used in the electric circuit further affects the total circuit resistance and, accordingly, the amount of current flowing to the blade cartridge for heating the blades. In other embodiments, the dissimilar material conductors may be used to regulate current flow to alternative electrically conductive components.

主权项

1. A shaving device adapted to receive electric current flow from an electric power source, said device comprising:
a blade cartridge including at least one electrically powered component; and an electric circuit for delivering the electric current flow from the electric power source to said at least one electrically powered component, and said electric circuit including:
a plurality of material conductors interconnected to one another, to said electric power source, and to said at least one electrically powered component and including at least a first material conductor, and a second material conductor, wherein each of said first and second material conductors has a different electric resistance that is selected for achieving a desired regulated electric current flow to said at least one electrically powered component, and wherein each of said plurality of material conductors has a unique width; and a switch selectively operable between an ON status for allowing the electric current flow from said electric power source through said electric circuit and an OFF status for interrupting the electric current flow through said electric circuit.
