Personal care device with separable coupling in drive train

A personal care device comprising:

• a head portion having a driven treatment head;
• a handle portion having a drive unit for providing a motion having a motion direction;
• and
• a drive train extending between the drive unit and the driven treatment head for transmitting the motion from the drive unit to the driven treatment head, the drive train comprising a separable coupling;
• the separable coupling comprising:
• a first coupling part having a first coupling element;
• a second coupling part having a second coupling element, the first and the second coupling elements being separably engaged with each other;
• and
• a resilient element biasing the first coupling element and the second coupling element against each other so that the first and second coupling elements are engaged in a gap-free manner along the motion direction, wherein the driven treatment head and the handle portion are arranged for being pivotable with respect to each other around at least a first pivot axis and the separable coupling is a separable universal joint.
