Abstract

A rechargeable pack is provided for containing and recharging an e-cigarette. The pack includes a pack battery; a first connector which is electrically connectable to an external power source; a first recharging mechanism for re-charging the pack battery using the external power source when the first connector is electrically connected to the external power source; a second connector which is electrically connectable to the e-cigarette when the e-cigarette is received within the pack; and a second recharging mechanism for re-charging the e-cigarette using the pack battery when the e-cigarette is electrically connected to the second connector. The second recharging mechanism can be configured to provide protection against the pack battery providing excessive current through the second connector.

First claim

The invention claimed is:

1. A rechargeable pack for containing and recharging an e-cigarette, the pack comprising:
a pack battery;
a first connector which is electrically connectable to an external power source;
a first recharging mechanism for re-charging the pack battery using the external power source when the first connector is electrically connected to the external power source;
a second connector which is electrically connectable to the e-cigarette when the e-cigarette is received within the pack; and
a second recharging mechanism for re-charging the e-cigarette using the pack battery when the e-cigarette is electrically connected to the second connector;
wherein the second recharging mechanism is configured to provide protection against the pack battery providing excessive current through the second connector, and wherein the second recharging mechanism acts to cut off a current through the second connector if the current exceeds a predetermined threshold value.

2. The pack of claim 1 , further comprising a tube which in normal use has a substantially vertical orientation, such that the e-cigarette received into the tube engages the second connector under the force of gravity.

3. The pack of claim 1 , wherein the predetermined threshold value is set at approximately twice a level of current for re-charging the e-cigarette according to normal specified operating conditions.

4. The pack of claim 1 , wherein the pack can be reset after the cut off to allow the second recharging mechanism to provide power again for re-charging through the second connector.

5. The pack of claim 4 , wherein the pack further comprises a lid which can be opened to provide access to receive the e-cigarette into the pack and closed to contain the e-cigarette within the pack, and wherein the reset is performed by opening the lid.

6. The pack of claim 1 , wherein the second recharging mechanism includes a thermal resettable fuse to perform the cut off.

7. The pack of claim 1 , wherein the second recharging mechanism is configured to obtain confirmation that the e-cigarette has been received into the pack before supplying power for re-charging to the second connector.

8. The pack of claim 7 , wherein the second recharging mechanism is configured to supply power to the second connector for a limited period while the confirmation is being obtained, and then to discontinue supplying power to the second connector if no confirmation is obtained.

9. The pack of claim 1 , wherein the second recharging mechanism is positioned between the pack battery and other components of the pack including the first recharging mechanism, the first connector, and the second connector.

10. The pack of claim 1 , further comprising an insert having at least one opening for receiving an e-cigarette.

11. The pack of claim 1 , further comprising a set of one or more LED lights to indicate a charging state of the pack.

12. The pack of claim 1 , wherein the e-cigarette received into the pack can be recharged via the first connector using the external power source.

13. The pack of claim 1 , wherein the first connector may be used to update software on a printed circuit board located in the pack.

14. The pack of claim 1 , wherein the first connector may be used to download usage data from the e-cigarette received into the pack.

15. The pack of claim 1 , wherein the pack battery and the e-cigarette received into the pack can be re-charged simultaneously from the external power source.

16. The pack of claim 1 , further comprising a temperature sensor in thermal contact with the pack battery.

17. The pack of claim 1 , further comprising an induction coil for recharging the e-cigarette received into the pack.

18. The pack of claim 1 , further comprising a facility to detect whether an e-cigarette has been received into the pack.
