Shaving unit and an electric shaver having the shaving unit

A shaving unit for use in a shaving device, the shaving unit comprising:

• a base portion comprising a coupling structure for coupling the shaving unit to a main housing of the shaving device;
• at least two hair-cutting units each having a hair-collecting chamber;
• a supporting member centrally arranged between the at least two hair-cutting units and having a central axis that extends centrally through the supporting member to the coupling structure,
• wherein each of the at least two hair-cutting units is connected to the supporting member and is configured to accommodate an external cutting member having a plurality of hair-entry openings and an internal cutting member which is rotatable relative to the external cutting member,
• wherein each of the at least two hair-cutting units comprises:
• a cutting unit housing configured to support the external and internal cutting members of a respective hair-cutting unit of the at least two hair-cutting units,
• wherein each of the cutting-unit housings is pivotably connected to the supporting member independently from the cutting-unit housing of each other hair-cutting unit and each connection defines a corresponding pivot axis;
• a guide shaft mounted in a fixed position to the base portion and having a shaft axis extending parallel to the movement direction of the supporting member;
• a set of guide elements, each of the guide elements mounted in a fixed position to the base portion and each being radially spaced from the shaft axis of the guide shaft;
• a guide bush mounted in a fixed position to the supporting member and arranged for a sliding motion over the guide shaft parallel to the shaft axis for enabling linear movement of the supporting member relative to the base portion in the movement direction;
• a set of guide members, each of the guide members mounted in a fixed position to the supporting member and each of the guide members being arranged for engaging a respective one of the set of guide elements to allow linear movement of the supporting member relative to the base portion in a movement direction parallel to the central axis of the supporting member between a first retracted position and a second extended position;
• wherein, seen in the movement direction, the guide shaft and the guide bush are arranged at a distance from the set of guide elements and the set of guide members;
• and
• a spring member positioned between the supporting member and the base portion for biasing the supporting member away from the base portion in the movement direction towards the second extended position.
