Abstract

A shaving system is disclosed comprising a shaving unit ( 14 ) and a cleaning device ( 22 ), wherein the shaving unit ( 14 ) comprises at least one hair-cutting unit having a movable hair-cutting member; the cleaning device ( 22 ) comprises a supporting structure for supporting the shaving unit ( 14 ), and a receiving space ( 26 ) for receiving the shaving unit ( 14 ) when the shaving unit ( 14 ) is arranged in a cleaning position supported by the supporting structure ( 24 ); and the cleaning device ( 22 ) comprises a reservoir ( 32 ) for containing a cleaning liquid and a fluid pumping unit ( 38 ) for transporting the cleaning liquid from the reservoir ( 32 ) to the receiving space ( 26 ); wherein the shaving unit ( 14 ) comprises a driven coupling member ( 30 ) which is accessible from an outside of the shaving unit ( 14 ) and which is coupled to the movable hair-cutting member such that the movable hair-cutting member is drivable by the driven coupling member ( 30 ); the cleaning device ( 22 ) comprises a driving coupling member ( 28 ) which is accessible from an outside of the cleaning device ( 22 ), and an electric actuator ( 34 ) coupled to the driving coupling member ( 28 ) such that the driving coupling member ( 28 ) is drivable by the electric actuator ( 34 ); and the driving coupling member ( 28 ) and the driven coupling member ( 30 ) are arranged such that, in the cleaning position of the shaving unit ( 14 ), the driven coupling member ( 30 ) is coupled to the driving coupling member ( 28 ) such that the movable hair-cutting member is drivable by the driving coupling member ( 28 ) via the driven coupling member ( 30 ).

Claims (47)

1. A shaving system comprising a shaving unit and a cleaning device, wherein:

the shaving unit comprises:

at least one hair-cutting unit having a movable hair-cutting member, and

a driven coupling member which is accessible from an outside of

the shaving unit and which is coupled to the movable hair-cutting member such that

the movable hair-cutting member is drivable by the driven coupling member;

the cleaning device comprises:

a supporting structure for supporting the shaving unit,

a receiving space for receiving the shaving unit when the shaving unit is arranged in a cleaning position supported by the supporting structure,

a reservoir for containing a cleaning liquid,

a fluid pumping unit for transporting the cleaning liquid from the reservoir to the receiving space;

a driving coupling member which is accessible from an outside of the cleaning device, and

an electric actuator coupled to the driving coupling member such that the driving coupling member is drivable by the electric actuator; and

the driving coupling member and the driven coupling member are arranged such that, in the cleaning position of the shaving unit, the driven coupling member is coupled to the driving coupling member such that the movable hair-cutting member is drivable by the driving coupling member via the driven coupling member.

2. The shaving system as claimed in claim 1 , wherein the fluid pumping unit is drivable by the electric actuator.

3. The shaving system as claimed in claim 1 , wherein the cleaning device comprises a control unit configured and arranged for controlling the driving of the driving coupling member by the electric actuator according to a driving program.

4. The shaving system as claimed in claim 3 , wherein the cleaning device comprises a user interface coupled to the control unit by which a user of the shaving system can activate the driving program.

5. The shaving system as claimed in claim 1 , further comprising a main housing accommodating a motor and a further driving coupling member coupled to the motor such that the further driving coupling member is drivable by the motor, the shaving unit and the main housing together forming a shaving device; wherein

the shaving unit further comprises a coupling structure configured for releasably coupling the shaving unit to the main housing, said coupling structure having a further driven coupling member which is coupled to the movable hair-cutting member such that the movable hair-cutting member is drivable by the further driven coupling member;

when the shaving unit is coupled to the main housing by the coupling structure, the further driven coupling member is coupled to the further driving coupling member such that the movable hair-cutting member is drivable by the motor via the further driving coupling member and the further driven coupling member.

6. The shaving system as claimed in claim 5 , wherein the shaving unit further comprises:

at least two hair-cutting units each having an external cutting member and an internal cutting member which is rotatable relative to the external cutting member; and

a drive unit which is coupled to the driven coupling member and to the internal cutting member of each hair-cutting unit such that the internal cutting member of each hair-cutting unit is drivable by the driven coupling member;

wherein the driven coupling member is arranged centrally between the at least two hair-cutting units.

7. The shaving system as claimed in claim 5 , wherein the shaving unit further comprises:

three hair-cutting units each having an external cutting member and an internal cutting member which is rotatable relative to the external cutting member; and

a drive unit which is coupled to the driven coupling member and to the internal cutting member of each hair-cutting unit such that the internal cutting member of each hair-cutting unit is drivable by the driven coupling member;

wherein the three hair-cutting units are mutually arranged in a triangular configuration and the driven coupling member is arranged centrally between the three hair-cutting units.

8. A cleaning device for use in a shaving system, said cleaning device comprising:

a supporting structure for supporting a shaving unit of a shaving device;

a receiving space for receiving the shaving unit when the shaving unit is arranged in a cleaning position supported by the supporting structure;

a reservoir for containing a cleaning liquid;

a fluid pumping unit for transporting the cleaning liquid from the reservoir to the receiving space;

a driving coupling member which is accessible from an outside of the cleaning device; and

an electric actuator coupled to the driving coupling member such that the driving coupling member is drivable by the electric actuator.

9. The cleaning device as claimed in claim 8 , wherein the driving coupling member is accessible and arranged such that, in the cleaning position of the shaving unit, the driving coupling member is coupled to a driven coupling member of the shaving unit such that a movable hair-cutting member of the shaving unit is drivable by the driving coupling member via the driven coupling member.

10. The cleaning device as claimed in claim 8 , wherein the driving coupling member is arranged in the receiving space.

11. The cleaning device as claimed in claim 10 , wherein the driving coupling member is arranged centrally in a bottom wall of the receiving space.

12. The cleaning device as claimed in claim 8 , wherein the fluid pumping unit is drivable by the electric actuator.

13. The cleaning device as claimed in claim 8 , wherein the receiving space is configured to receive a shaving unit having three hair-cutting units.

14. The cleaning device as claimed in claim 13 , wherein the driving coupling member is positioned such that it extends upwardly between the three hair cutting units when the shaving unit is arranged in the cleaning position.

15. The cleaning device as claimed in claim 8 , wherein the driving coupling member protrudes upwardly through a bottom wall of the receiving space.

16. The cleaning device as claimed in claim 15 , wherein the electric actuator is configured to rotate the driving coupling member.

17. The cleaning device as claimed in claim 16 , wherein a distal end of the driving coupling member is configured for engagement with a rotatable member of the shaving unit when the shaving unit is arranged in the cleaning position.

18. The cleaning device as claimed in claim 17 , wherein the distal end of the driving coupling member is configured for insertion into the rotatable member of the shaving unit when the shaving unit is arranged in the cleaning position.

19. The cleaning device as claimed in claim 8 , wherein the cleaning device comprises a control unit configured and arranged for controlling the driving of the driving coupling member by the electric actuator according to a driving program.

20. The cleaning device as claimed in claim 19 , wherein the cleaning device comprises a user interface coupled to the control unit by which a user of the shaving system can activate the driving program.
