SHAVING CARTRIDGES HAVING THERMAL SENSORS

摘要

A shaving razor cartridge (12) having a housing (18) with a guard (20), a cap (22), and one or more blades (24) located between the guard and the cap. The guard is positioned in front of the one or more blades and the cap is positioned behind said one or more blades. A heating element (16) is mounted to the housing for transferring heat during a shaving stroke. The heating element has a skin contacting surface (30). An insulating member (40) is positioned beneath the skin contacting surface for delivering heat to the heating element. An electrical circuit (100) is configured to deliver energy to the insulating member. The electrical circuit includes a control circuit (102) for temperature regulation. A power source (104) in communication with the electrical circuit. A plurality of spaced apart thermal sensors (50, 52) are mounted to the insulating member and positioned below the skin contacting surface. The thermal sensors measure the temperature of the heating element and are in communication with the control circuit.
