    • The present invention relates to a device for actuating a unit that actuates household appliances, especially electric razors. Said actuating unit can be driven in a rotatory oscillating manner. The inventive actuating device is provided with a permanent magnet motor which is provided with a stator comprising an exciting winding and a rotor that is arranged in the stator field and is rotationally mounted around a rotational axis. Said rotor is provided with at least one permanent magnet. The inventive actuating device is also provided with a readjusting device which readjusts the rotor into a neutral position in such a way that the rotor can oscillate around the neutral position. The inventive device is also provided with a coupling device which couples the rotor to the actuating unit. Said coupling device is fixed to the rotor at a certain distance from the rotational axis. The inventive device also comprises a detector which detects the oscillatory movements of the rotor and an actuating device which actuates the permanent magnet according to the oscillatory movements thus detected. Frequency control means which have a frequency which corresponds approximately to the resonance frequency of the rotor are provided in order to control the permanent magnet motor.

    • The present invention relates to a lower cutter (4) for a shaving head, equipped with an upper cutter (7), of an electric razor, comprising at least one blade (10) which has a cutting edge (11) pointing in a direction of movement. The invention also relates to a shaving head having such a lower cutter and to an electric razor equipped with it. It is proposed to no longer give the cutting edge the conventional wedge-shaped configuration in which simply two planes inclined at an acute angle define the cutting edge contour. According to the invention, the cutting edge has, one behind the other in the direction of movement (16), at least two cutting edge sections (18,19) having different cutting angles. By means of a cutting angle graduation or a changing cutting angle, an optimum compromise can be achieved between the conflicting requirements of cutting behaviour and edge stability. The cutting edge section having the more obtuse or less acute cutting angle produces the desired cutting edge stability and at the same time provides for a long service life. On the other hand, the cutting edge sections having the more acute angle reduce the cutting forces, such that an improved threading behaviour can be achieved.
    • 本发明涉及一种用于具有顶部(7)的干剃须刀的装有剃须头刀的下刀片(4),其包括具有在所述切削刃(11)的运动方向上的面对的至少一个叶片(10)。 本发明还涉及一种具有这种较低的切割器和一个所谓的装有干式剃须器的剃须头。 所以建议不设置切割刃时,传统的楔形形状,其中限定所述切削轮廓只是两个锐角倾斜平面。 根据本发明,在移动方向(16)一个在另一个的至少两个切削部分(18,19)具有不同的切削角度后面的切削刃。 通过切割角灰度或改变切割角度可达到切削刃的性能和稳定性发散要求之间的最佳折衷。 切断部到所述消光剂或更少急性切割角度提供了所需的切削稳定性,并确保长的使用寿命。 与她的切割角的切削部,但是,降低切削力,从而能够实现一种改进的拉动力。
