System for regulating electric current flow from a power source to a blade cartridge in a wet shave razor
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.
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.
2. The shaving device as recited in claim 1 wherein said switch is operable to a plurality of ON status positions to selectively change a total resistance of the electric circuit at each of the plurality of ON status positions.
3. The shaving device as recited in claim 2 wherein operation of said switch between each of the plurality of ON status positions changes the amount of electric current flow to said at least one electrically powered component.
4. The shaving device as recited in claim 1 wherein said at least one electrically powered component is at least one electrically conductive blade.
5. The shaving device as recited in claim 1 wherein said at least one electrically powered component is at least one heating element in contact with at least one blade in said blade cartridge.
6. The shaving device as recited in claim 1 wherein said at least one electrically powered component is at least one heating element in contact with said blade cartridge.
7. The shaving device as recited in claim 1 wherein said at least one electrically powered component is at least one light.
8. 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;
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 said plurality of material conductors including:
a first material conductor;
a second material conductor; and
a third material conductor;
each of said first, second, and third material conductors being selected from a group consisting of at least two dissimilar materials having different electric resistances that are selected for achieving a desired regulated electric current flow to said at least one electrically powered component; 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.
