A personal care device like a shaving device () comprises a base structure () and a head structure (). The head structure comprises a first coupling element () and at least a head support structure () configured to hold at least one treatment head ('). The base structure comprises a second coupling element (). The coupling elements can releasably be coupled to each other for coupling the head structure to the base structure. By rotating the coupled coupling elements with respect to each other in a first rotational direction about a central axis (), a first inclined surface () of at least one of the first and second coupling elements cooperates with a first co-operating surface () of the other of the first and second coupling elements thereby driving the first and second coupling elements away from each other in an axial direction extending parallel to the central axis.

Coupling structure for a personal care device

A personal care device comprising a main housing, a hair-cutting module displaceable with respect to the main housing against spring force in a direction parallel to a main axis, and a sensor comprising a first sensor unit connected to the main housing and a second sensor unit connected to the hair-cutting module. The hair cutting module is also tiltable in directions relative to the main housing. By measuring average displacement of the hair cutting module at multiple locations, the sensor is sensitive only to displacement parallel to the main axis. The sensor measures such displacement and determines the force needed to effect such displacement. If the force is larger than a predetermined value, a warning signal will be produced.
