Abstract
The present invention relates to the field of small electrical appliances such as battery powered electrical appliances for personal hygiene, in particular to a hair removal device such as an electric shaver or epilator as well as an electric toothbrush. The small electrical appliance comprises an electric load, wherein the electric load heats up during operation; a measuring circuitry for measuring an electrical parameter of the electric load; a temperature sensor arranged spatially separated from the electric load; and control circuitry adapted to protect the electric load from overheating by controlling the electric load based on the electrical parameter of the electric load and an output of the temperature sensor.
