Abstract

A shaving system comprising a shaving device and a cleaning device (14) is disclosed, wherein the shaving device comprises a main housing and a shaving unit coupled to the main housing, wherein the main housing accommodates an electric actuator and a first drive unit drivable by the electric actuator, the shaving unit comprising at least one hair-cutting unit and a second drive unit coupled to the first drive unit and to the hair-cutting unit such that the hair-cutting unit is drivable by the electric actuator via the first and second drive units; wherein the cleaning device (14) comprises a supporting structure (15) for supporting the shaving device, and a receiving space (28) for receiving the shaving unit when the shaving device is arranged in a cleaning position supported by the supporting structure (15); and wherein the cleaning device (14) comprises a reservoir (32) for containing a cleaning liquid and a fluid pumping unit (48) for transporting the cleaning liquid from the reservoir (32) to the receiving space (28); wherein the shaving device comprises a driving coupling member which is accessible from an outside of the shaving device and drivable by the shaving device; wherein the cleaning device (14) comprises a driven coupling member (30) which is accessible from an outside of the cleaning device (14), and a third drive unit (50) coupled to the driven coupling member (30) and to the fluid pumping unit (48) such that the fluid pumping unit (48) is drivable by the driven coupling member (30); and wherein the driving coupling member and the driven coupling member (30) are arranged such that, in the cleaning position of the shaving device, the driven coupling member (30) is coupled to the driving coupling member such that the fluid pumping unit is drivable by the driving coupling member.

First claim

The invention claimed is:

1. A shaving system comprising a shaving device and a cleaning device, wherein:
the shaving device comprises a main housing and a shaving unit coupled to the main housing, said main housing accommodating an electric actuator and a first drive unit drivable by the electric actuator, said shaving unit comprising at least one hair-cutting unit and a second drive unit coupled to the first drive unit and to the hair-cutting unit such that the hair-cutting unit is drivable by the electric actuator via the first and second drive units;
the cleaning device comprises a supporting structure for supporting the shaving device, and a receiving space for receiving the shaving unit when the shaving device is arranged in a cleaning position supported by the supporting structure; and
the cleaning device comprises a reservoir for containing a cleaning liquid and a fluid pumping unit for transporting the cleaning liquid from the reservoir to the receiving space;

characterized in that:
the shaving device comprises a driving coupling member which is accessible from an outside of the shaving device and drivable by the shaving device;
the cleaning device comprises a driven coupling member which is accessible from an outside of the cleaning device, and a third drive unit coupled to the driven coupling member and to the fluid pumping unit such that the fluid pumping unit is drivable by the driven coupling member; and
the driving coupling member and the driven coupling member are arranged such that, in the cleaning position of the shaving device, the driven coupling member is coupled to the driving coupling member such that the fluid pumping unit is drivable by the driving coupling member.

2. The shaving system as claimed in claim 1 , wherein the driving coupling member is drivable by the electric actuator.

3. The shaving system as claimed in claim 2 , wherein the driving coupling member is arranged in the shaving unit and coupled to the second drive unit such that the driving coupling member is drivable by the electric actuator via the first and second drive units.

4. The shaving system as claimed in claim 3 , wherein the shaving unit 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 wherein the driving coupling member is arranged centrally between the at least two hair-cutting units.

5. The shaving system as claimed in claim 4 , wherein the shaving unit 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, wherein the three hair-cutting units are mutually arranged in a triangular configuration and wherein the driving coupling member is arranged centrally between the three hair-cutting units.

6. The shaving system as claimed in claim 1 , wherein the driving coupling member is only driveable when the shaving device is in the cleaning position.

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

8. The shaving system as claimed in claim 7 , wherein the shaving device comprises a user interface coupled to the control unit by means of which a user of the shaving system can activate the driving program.

9. The shaving system as claimed in claim 7 , wherein the shaving device comprises a detector coupled to the control unit for detecting the cleaning position, and wherein the control unit is configured and arranged to activate the driving program after detection of the cleaning position by the detector.

10. The shaving system as claimed in claim 1 , wherein the driven coupling member is arranged in the receiving space.

11. The shaving system as claimed in claim 10 , wherein the driven coupling member is arranged centrally in a bottom wall of the receiving space.

12. The shaving system as claimed in claim 1 , wherein the reservoir is replaceable.

13. The shaving system as claimed in claim 12 , wherein the cleaning device comprises a lower housing portion and an upper housing portion detachably coupled to the lower housing portion, wherein the reservoir is arranged in the lower housing portion and accessible for replacement by removing the upper housing portion from the lower housing portion, and wherein the supporting structure, the receiving space, the driven coupling member and the fluid pumping unit are arranged in the upper housing portion.

14. The shaving system as claimed in claim 13 , wherein the drive unit and the fluid pumping unit are arranged in the upper housing portion.

15. The shaving system as claimed in claim 1 , wherein the reservoir is integrally formed with the cleaning device.

16. The shaving system as claimed in claim 1 , wherein the shaving unit 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, wherein the three hair-cutting units are mutually arranged in a triangular configuration and wherein the driving coupling member is arranged centrally between the three hair-cutting units such that the driving coupling member is accessible from the outside of the shaving unit.

17. The shaving system as claimed in claim 1 , wherein:
the shaving unit is coupled to the main housing by means of a coupling structure;
the second drive unit comprises a driving gear wheel which is centrally arranged relative to the at least two hair-cutting units to engage a respective driven gear wheel of each of the hair-cutting units;
the coupling structure accommodates a central drive shaft mutually coupling the driving gear wheel and the first drive unit; and
the driving coupling member is connected to the driving gear wheel such as to be rotatable together with the driving gear wheel about a common axis of rotation.
