Abstract

A personal care product system is provided. The personal care product system has a stand that has a first stand permanent docking magnet. A stand inductive charging coil is also positioned within the stand. A handle that has a first handle permanent docking magnet is removably mounted to the stand. A handle inductive charging coil is positioned within the handle. A handle flux guiding member is in close proximity to a surface of the first handle permanent docking magnet to direct a magnetic field away from the inductive charging coils.

Claims (45)

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; and

a handle flux guiding member in close proximity to a surface of the first handle permanent docking magnet, wherein the handle flux guiding member comprises a yoke with a first leg extending through the handle inductive charging coil, a second leg extending outside the handle inductive charging coil, wherein each of the first leg and the second leg has an angled end surface.

2. The personal care product system of claim 1 , further comprising a second handle permanent docking magnet positioned within the handle wherein the handle flux guiding member connects the first handle permanent docking magnet and the second handle permanent docking magnet.

3. The personal care product system of claim 1 , further comprising a second stand permanent docking magnet positioned within the stand and a stand flux guiding member, wherein the stand flux guiding member connects the first stand permanent docking magnet and the second stand permanent docking magnet.

4. The personal care product system of claim 1 , further comprising a stand flux guiding member having a first leg positioned within the stand inductive charging coil, wherein an outer surface of the first stand permanent docking magnet and an outer side surface of the first leg are positioned within about 7 mm of each other.

5. The personal care product system of claim 1 , wherein an outer surface of the first handle permanent docking magnet and an outer side surface of the first leg are positioned within about 6 mm of each other.

6. The personal care product system of claim 2 , wherein an outer surface of the second handle permanent docking magnet and an outer side surface of the first leg are positioned within about 3 mm of each other.

7. The personal care product system of claim 3 , wherein an outer surface of the second stand permanent docking magnet and an outer side surface of the first leg are positioned within 3 about mm of each other.

8. The personal care product system of claim 1 , wherein the handle flux guiding member has an L-shaped cross section.

9. The personal care product system of claim 1 , wherein the handle inductive charging coil has a center axis generally axially aligned with a center axis of the stand inductive charging coil.

10. The personal care product system of claim 1 , wherein the handle flux guiding member is a bar.

11. 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 and a second handle permanent docking magnet positioned within the handle, wherein the first and second handle permanent docking magnets are configured to collectively 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; and

a handle flux guiding member in close proximity to a surface of the first handle permanent docking magnet and a surface of the second handle permanent docking magnet wherein the handle flux guiding member comprises a yoke with a first leg extending through the handle inductive charging coil, a second leg extending outside the handle inductive charging coil, wherein each of the first leg and the second leg has an angled end surface.

12. The personal care product system of claim 1 , 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 in the stand.

13. The personal care product system of claim 12 , wherein at least one of the first handle permanent docking magnet and the second handle permanent docking magnet directly contacts the inner surface of the handle and the first stand permanent docking magnet directly contacts the inner surface of the stand.

14. The personal care product system of claim 12 , wherein at least one of the first handle permanent docking magnet and the second handle permanent docking magnet has an angled end surface that directly contacts the inner surface of the handle.

15. The personal care product system of claim 12 , wherein the first stand permanent docking magnet has an angled end surface that directly contacts the inner surface of the stand.

16. The personal care product system of any one of claim 11 , wherein the handle has a spring member forcing the first handle permanent docking magnet against the inner surface of the handle.

17. 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 handle flux guiding member in close proximity to a surface of the first handle permanent docking magnet, the handle flux guiding member comprises a yoke with a first leg extending through the handle inductive charging coil, a second leg extending outside the handle inductive charging coil, each of the first leg and the second leg has an angled end surface; and

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

18. The personal care product system of claim 17 , wherein the handle flux guiding member and the stand flux guiding member each have an L-shaped cross section.

19. The personal care product system of claim 17 , wherein the handle flux guiding member and the stand flux guiding member are each a bar.

20. The personal care product system of claim 17 , wherein the handle flux guiding member and the stand flux guiding member each comprises a ferrimagnetic material or a ferromagnetic material.
