  • Patent number: 9751227
    Abstract: A method 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.

  • Patent number: 9604375
    Abstract: A blade cartridge for a shaving razor contains a series of parallel blades and at least two contact segments as part of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. A radiator effect is created wherein heat produced by the contact segments passes between the blades towards the cutting edge of the blades. The combination of the heat produced by the electric current flow through the conductive blades and the heat produced by the contact segments provides a dual heat process that makes it easier to adjust and control the temperature to a desired stable heat temperature. A thin conductive film may be fitted to be in contact with the ends of the blades to insure conductivity throughout the entire length of each blade.

  • Patent number: 9399304
    Abstract: A blade heating system for a heated razor includes electrically conductive blades contained in a blade cartridge. A switch lever is hingedly attached to the blade cartridge and is selectively positionable between a closed position, wherein the switch lever is closed against the back of the blade cartridge, and an open position, wherein the switch lever is opened away from the back of the blade cartridge. Electrically conductive leads are connected to positive and negative terminal ends of a battery carried on the switch lever. One or more electrically conductive blade contacts are provided for electrically connecting the one or more blades to the conductive leads and battery when the switch lever is in the closed position for delivering electric current to the one or more electrically conductive blades. In a preferred embodiment, magnets are used to releasably hold the switch lever closed against the back of the blade cartridge.

  • Publication number: 20150298326
    Abstract: A shaving razor includes one or more heaters held in spaced, adjacent relation to the rear non-cutting edge of at least one blade of the razor. The one or more heaters are in connection with an electric power source, which may be located in the blade cartridge or in the handle of the razor. When the electric circuit is closed and electric current flows through the heaters, the heaters generate heat that is directed between the blades and towards the front cutting edge of the blades in a radiator effect. The heaters serve to warm the blades while also providing warmth to the user's skin for increased shaving performance and comfort. In a preferred embodiment, the heaters are made from a high resistance material, such as Nichrome, for producing heat with maximum efficiency.

  • Patent number: 9149945
    Abstract: A razor having a handle and a blade cartridge containing one or more blades includes an electric circuit with a battery power source for controlled direction of current flow through the one or more blades in order to heat the blades. The electric circuit further includes opposing electrically conductive contact leads, the battery power source, and an electrically conductive contactor in contact with an ON/OFF switch all housed on the blade cartridge. A housing for the battery and switch extends transversely in spaced and separated relation to the blades and defines a bridge structure over an open gap between the housing and the blades for allowing a directed stream of water flow to pass below the housing, through the gap and between the plurality of electrically conductive blades for rinsing debris from surfaces of the blades.

  • Patent number: 8713801
    Abstract: A blade cartridge for a shaving razor contains a series of parallel blades, and at least two wire conductors of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. The ends of the blades may be held in place by staples that are insulated from the electric circuit. A thin conductive film may be fitted to be in contact with the ends of the blades to insure conductivity throughout the entire length of each blade. A radiator effect of the heated blades causes the blades to become warmer when the blades are placed against the skin surface and air is unable to circulate between the blades. The blades become less hot when removed from the skin and air circulates between the blades.
