Abstract

This disclosure is concerned with a personal care device with a treatment head being pivot-mounted around a pivot axis, the personal care device having a pin having a pin head, a cam element having a cam surface, a spring element biasing the pin head and the cam surface against each other, wherein the cam surface is shaped such that it defines a rest position at which the biasing spring force provided by the spring element with which the pin head and the cam surface are pushed against each other has a non-zero minimum value, and wherein a pivoting of the head around the pivot axis causes the pin head to move along the cam surface and the cam surface is further shaped such that the spring force pushing the pin head and the cam surface against each other increases with increasing pivoting angle.
