Abstract

A personal care product system is provided. The personal care product system has a stand that has a first and second stand permanent docking magnet. A stand inductive charging coil is also positioned within the stand. A handle that has first and second handle permanent docking magnets is removably mounted to the stand. A handle inductive charging coil is positioned within the handle. The handle has a first handle flux guiding member and a second handle flux guiding member. The stand has a first stand flux guiding member.

Claims

1. A personal care product system comprising:

a stand;

a first stand permanent docking magnet positioned within the stand;

a stand inductive charging coil positioned within the stand;

a handle removably mounted to the stand;

a rechargeable battery positioned within the handle;

a first handle permanent docking magnet positioned within the handle configured to generate an attraction force sufficient to hold the handle to the stand when placed in proximity to the first stand permanent docking magnet;

a handle inductive charging coil positioned within the handle, wherein the stand inductive charging coil is configured to generate a magnetic field that penetrates the handle inductive charging coil to charge the rechargeable battery;

a first handle flux guiding member having at least a portion positioned within the handle inductive charging coil;

a second handle flux guiding member in close proximity to a surface of the first handle permanent docking magnet;

a first stand flux guiding member having at least a portion positioned within the stand inductive charging coil.

2. The personal care product system according to claim 1, wherein

an outer surface of the first stand permanent docking magnet and an outer side surface of the portion positioned within the stand inductive charging coil are positioned within 7 mm of each other;

and

an outer surface of the first handle permanent docking magnet and an outer side surface of the portion positioned within the handle inductive charging coil are positioned within 6 mm of each other.

3. The personal care product system of claim 1, wherein

at least another portion of the first handle flux guiding member extends external to the handle inductive charging coil;

and

at least another portion of the first stand flux guiding member extends external to the stand inductive charging coil.

4. The personal care product system of claim 1, wherein the portion of the first handle flux guiding member positioned within the handle inductive charging coil is generally axially aligned with the portion of the first stand flux guiding member positioned within the stand inductive charging coil when the handle is held to the stand.

5. The personal care product system of claim 1, wherein the handle inductive charging coil has a center axis that is generally axially aligned with a center axis of the stand inductive charging coil when the handle is held in the stand.

6. A personal care product system comprising:

a stand;

a first stand permanent docking magnet positioned within the stand;

a stand inductive charging coil positioned within the stand;

a handle removably mounted to the stand;

a rechargeable battery positioned within the handle;

a first handle permanent docking magnet positioned within the handle configured to generate an attraction force sufficient to hold the handle to the stand when placed in proximity to the first stand permanent docking magnet;

a handle inductive charging coil positioned within the handle, wherein the stand inductive charging coil is configured to generate a magnetic field that penetrates the handle inductive charging coil to charge the rechargeable battery;

a first handle flux guiding member having at least a portion positioned within the handle inductive charging coil;

a second handle flux guiding member in close proximity to a surface of the first handle permanent docking magnet;

a first stand flux guiding member having at least a portion positioned within the stand inductive charging coil; and

a second stand flux guiding member in close proximity to a surface of the first stand permanent docking magnet.

7. The personal care product system of claim 6, wherein the second handle flux guiding member is generally parallel to the second stand flux guiding member when the handle is held in the stand.

8. The personal care product system of claim 6, wherein the first flux guiding member of the stand has a U-shaped cross section or an E-shaped cross section and the first flux guiding member of the handle has a U-shaped cross section or an E-shaped cross section.

9. The personal care product system of claim 6, wherein the second handle flux guiding member is bar-shaped.

10. The personal care product system of claim 6, wherein one or more of the first and second handle flux guiding members of the handle and the first stand flux guiding member comprises a ferrimagnetic material or a ferromagnetic material.

11. The personal care product system of claim 6, further comprising a second handle permanent docking magnet positioned within the handle wherein the second handle flux guiding member connects the first handle permanent docking magnet and the second handle permanent docking magnet.

12. The personal care product system of claim 6, further comprising a second stand permanent docking magnet positioned within the stand.

13. The personal care product system of claim 6, wherein the handle has an outer contact surface and an opposing inner surface, the stand has an outer contact surface and an opposing inner surface, the outer contact surface of the stand and the outer contact surface of the handle are in direct contact when the handle is held to the stand.

14. The personal care product system of claim 13, wherein the first handle flux guiding member directly contacts the inner surface of the handle and the first stand flux guiding member directly contacts the inner surface of the stand.

15. The personal care product system of claim 13, wherein the handle has a spring member forcing the first handle permanent docking magnet against the inner surface of the handle.

16. A personal care product system comprising:

a stand;

a stand inductive charging coil positioned within the stand;

a handle removably mounted to the stand;

a rechargeable battery positioned within the handle;

a first handle permanent docking magnet positioned within the handle configured to generate an attraction force sufficient to hold the handle to the stand when placed in proximity to the stand;

a handle inductive charging coil positioned within the handle, wherein the stand inductive charging coil is configured to generate a magnetic field that penetrates the handle inductive charging coil to charge the rechargeable battery;

a first handle flux guiding member positioned proximate to the handle inductive charging coil;

a second handle flux guiding member positioned proximate to a surface of the first handle permanent docking magnet; and

a first stand flux guiding member positioned proximate to the stand inductive charging coil.

17. The personal care product system of claim 16, wherein the first handle flux guiding member has a portion positioned within the handle inductive charging coil.

18. The personal care product system of claim 17, wherein the first stand flux guiding member has a portion positioned within the stand inductive charging coil.

19. The personal care product system of claim 18, wherein the portion of the first handle flux guiding member positioned within the handle inductive charging coil is generally axially aligned with the position of the first stand flux guiding member positioned within the stand inductive charging coil when the handle is held to the stand.
