SHAVING CARTRIDGES WITH THERMAL SENSORS Russian patent published in 2018 - IPC B26B21/48 

FIELD: personal usage items.

SUBSTANCE: inventions relate to the means for wet shaving with heating. Shaving apparatus comprises a housing with at least one blade, a heating element, an insulating member for supplying heat to the heating element and the electric circuit. Electrical circuit contains a temperature control circuit. Power source connected to the electrical circuit and spatially separated temperature sensors are provided. Sensors are mounted on the insulating element and are located below the surface of the heating element in contact with the user's skin. Sensors measure the temperature of the heating element and are connected to the temperature control circuit. Regulate the transfer of heat to the user's skin while shaving. To this end, the temperature of the first and second regions of the heating element is measured by sensors. Based on the comparison of the temperature values of both sensors with the set temperature of the heating element, its temperature is lowered.

EFFECT: as a result, a safe and effective heating is experienced by the user when the shaving device is passed.
