Drive component for electric shaver

1. An electric shaver comprising:

a handle;

a head connected to the handle, wherein the head comprises an outer cutter blade and an inner cutter blade arranged in shearing contact with the outer cutter blade; and

a drive system comprising a motor and a plurality of drive components drivingly connecting the motor to the inner cutter blade for driving rotation of the inner cutter blade relative to the outer cutter blade, wherein the plurality of drive components comprises a first drive component and a second drive component connected to the first drive component, wherein at least one of the first drive component and the second drive component comprises a liner for cushioning the interface between the first drive component and the second drive component to mitigate noise associated with operation of the shaver.

2. The electric shaver set forth in claim 1 wherein the liner is formed from a thermoplastic elastomer (TPE) material.

3. The electric shaver set forth in claim 1 wherein the second drive component is configured to receive the first drive component.

4. The electric shaver set forth in claim 3 wherein the first drive component comprises the liner.

5. The electric shaver set forth in claim 3 wherein the second drive component comprises the liner.

6. The electric shaver set forth in claim 1 wherein the second drive component is pivotable relative to the first drive component.

7. The electric shaver set forth in claim 6 wherein the electric shaver is a rotary electric shaver, the outer cutter blade and the inner cutter blade being pivotable on the head of the shaver, wherein the first drive component and the second drive component are pivotably connected to one another such that the inner cutter blade is drivable during pivoting.

8. The electric shaver set forth in claim 7 wherein the first drive component is a drive pin and wherein the second drive component is a drive cap to which the inner cutter blade is connected, the drive cap having a socket defined by the liner such that the drive pin is insertable into the socket for driving the inner cutter blade.

9. The electric shaver set forth in claim 8 wherein the socket is generally polygonal and wherein the drive pin comprises a tip that is generally polygonal.

10. The electric shaver set forth in claim 8 wherein the drive cap comprises a shell having an interior lined by the liner to define the socket, the shell being formed from a first material having a first hardness, the liner being formed from a second material having a second hardness that is less than the first hardness.

11. The electric shaver set forth in claim 10 wherein the second material is a thermoplastic elastomer (TPE) material.

12. The electric shaver set forth in claim 10 wherein the liner and the shell are keyed to one another to facilitate preventing rotation of the liner relative to the shell.

13. An inner cutter for an electric shaver, said inner cutter comprising:

a blade; and

a drive cap to which the blade is connected, the drive cap comprising a shell and a liner, wherein an interior of the shell is lined by the liner such that the liner defines a socket, the shell being formed from a first material having a first hardness, the liner being formed from a second material having a second hardness that is less than the first hardness.

14. The inner cutter set forth in claim 13 wherein the second material is a thermoplastic elastomer (TPE) material.

15. The inner cutter set forth in claim 13 wherein the liner and the shell are keyed to one another to facilitate preventing rotation of the liner relative to the shell.

16. The inner cutter set forth in claim 13 wherein the socket is configured to receive a drive component.

17. The inner cutter set forth in claim 16 wherein the socket is configured to permit pivoting of the drive cap on the drive component.

18. The inner cutter set forth in claim 16 wherein the socket is generally polygonal.

19. The inner cutter set forth in claim 18 wherein the generally polygonal socket has a generally square cross-sectional shape.

20. An electric shaver comprising:

a handle;

a head connected to the handle, wherein the head comprises an outer cutter blade and an inner cutter blade arranged in shearing contact with the outer cutter blade; and

a drive system comprising a motor and a plurality of drive components drivingly connecting the motor to the inner cutter blade for driving the inner cutter blade relative to the outer cutter blade, wherein the plurality of drive components comprises:

a drive cap to which the inner cutter blade is connected, the drive cap comprising a shell and a liner, wherein an interior of the shell is lined by the liner such that the liner defines a socket, the shell being formed from a first material having a first hardness, the liner being formed from a second material having a second hardness that is less than the first hardness; and

a torque transfer assembly comprising a basket, a biasing member seated within the basket, and a drive pin connected to the basket atop of the biasing member such that the drive pin is floatable, pivotable, and rotatably immovable relative to the basket,

wherein the torque transfer assembly drivingly connects the motor to the drive cap with the drive pin inserted into the socket such that the liner cushions the interface between the drive pin and the drive cap to mitigate noise associated with operation of the shaver.
