  • the shaving head system is designed in such a way that the entire usable shaving surface is continuously in contact with the skin surface while shaving.
  • the known system has proven itself in practice, but is subject to some restrictions. For a perfect swivel function, it is necessary to strictly limit the weight of the shaving head system and the position of its center of gravity. This places narrow limits on the arrangement of additional elements in the shaving head system if no deterioration in the mode of operation is to be accepted. In addition, in order to pivot the shaving head system so that the entire usable shaving surface comes into contact with the skin surface, the razor must be pressed against the skin. Another limitation is that the shaving head system can only be driven with the drive pin within a limited swivel angle range.

It is initially irrelevant for the applicability of the invention whether the actuator elements can be positioned individually or in groups or only all together. If there is only one actuator element overall, the user is generally able to make sufficient skin contact without additional aids. In certain applications and in particular when the actuator element is movable in several planes, use of the invention can also be advantageous in a hair removal device with a single actuator element. Another advantage of the invention is that there are no restrictions with regard to the weight and geometry of the actuator head and with regard to the accessible positioning range when the actuator head is positioned passively.

  • the collector resistors 14, 15 and 16 are still connected to one another and, like the housing 8 which the user 6 holds in his hand, are at an electrical potential Vdd. From the housing 8, there is an electrical connection to the second shaving foil 3 via the user 6, which has a body resistance 18. To make this possible, the housing 8 is at least partially electrically conductive. Depending on the position of the shaving head 1, corresponding electrical connections can also be made to the center cutter 4 and to the first shaving foil 2.
  • the body resistance 18 represents the total electrical resistance effective between the skin surface 5 and the hand of the user 6.

  • the current flow runs through the body resistance 18 and can therefore only be formed when the respective shaving foil 2 or 3 is applied to the skin surface 5. If, for example, in accordance with the situation shown in FIG. 1, the second shaving foil 3 bears against the skin surface 5 and thus a current flows through the body resistance 18 to the base of the second transistor 11, the second transistor 11 switches through and applies the input F2 to the control logic 13 , which is otherwise at the electrical potential Vdd, to ground. The same also applies to the first shaving foil 2 when it lies against the skin surface 5. Since only very low currents are required for the connection of the transistors 10, 11, 12, the current flow through the body resistance 18 is absolutely safe and imperceptible for the user 6.

In a variant, it is also possible to slowly pivot the shaving head 1 into a basic position if neither of the two shaving foils 2 and 3 abuts the skin surface 5. If only the first shaving foil 2 is not in contact with the skin surface 5, the adjusting device 7 is slowly moved to the right in the geometry shown in FIG. H. clockwise, rotated and thus the shaving head 1 pivoted to the left.
