Abstract

A charging system ( 10 ) for an aerosol-generating device ( 12 ) includes a charging unit ( 14 ). The charging unit includes a body ( 20 ) at least partially defining a receiving volume ( 22 ). The receiving volume is sized to receive the elongate aerosol-generating device through an open top end in a plurality of orientations. A charging interface is coupled to the body and includes a biasing element and an electrical contact. The biasing element is configured to apply a force on the aerosol-generating device that causes an electrical contact of the aerosol-generating device to electrically engage the electrical contact of the charging interface when the aerosol-generating device rests on the charging unit.

First claim

The invention claimed is:

1. A charging system for an aerosol-generating device comprising:
a body at least partially defining a receiving volume, wherein the receiving volume tapers along a longitudinal axis from an open top end portion to a bottom end portion, wherein the receiving volume is sized to receive an elongate aerosol-generating device through the open top end in a plurality of orientations, wherein the body is configured to cause the elongate aerosol-generating device to rest at a predefined tilt relative to the longitudinal axis; and
a charging interface coupled to the body comprising a first biasing element and a first electrical contact, wherein the first biasing element is configured to apply a force on a second biasing element of the aerosol-generating device that causes a second electrical contact of the aerosol-generating device to electrically engage the first electrical contact when the aerosol-generating device rests on the body at the predefined tilt.

2. The system of claim 1 , wherein the first biasing element is configured to attract the second biasing element of the aerosol-generating device.

3. The system of claim 1 , wherein the first biasing element is configured to cause the aerosol-generating device to rest in a predefined radial direction that aligns the first electrical contact with the second electrical contact.

4. The system of claim 1 , wherein the charging interface further comprises a third biasing element configured to repel the second biasing element of the aerosol-generating device.

5. The system of claim 4 , wherein the charging interface defines a surface of the bottom end portion of the body, wherein the charging interface comprises a first radial side portion including the first biasing element and a second radial side portion including the third biasing element.

6. The system of claim 4 , wherein at least one of the first biasing element and the third biasing element has an annular shape.

7. The system of claim 1 , wherein the first electrical contact comprises a pogo pin.

8. The system of claim 1 , wherein the charging interface is coupled to the bottom end portion of the body.

9. The system of claim 1 , wherein the biasing elements comprise magnets.

10. The system of claim 1 , wherein the body is configured to cause the aerosol-generating device to rest in a predefined radial direction that aligns the first electrical contact with the second electrical contact.

11. The system of claim 10 , wherein the bottom end portion of the body defines a surface that is not orthogonal to the longitudinal axis.

12. The system of claim 10 , wherein the bottom end portion of the body comprises a conical shape.

13. The system of claim 1 , further comprising a visual indicator that activates in response to the first electrical contact electrically engaging the second electrical contact.

14. The system of claim 1 , further comprising the aerosol-generating device having the second electrical contact and the second biasing element, wherein the second electrical contact is configured to electrically engage with the first electrical contact in any rotational orientation.

15. The system of claim 1 , further comprising the aerosol-generating device having the second electrical contact and the second biasing element, wherein the second electrical contact is not aligned to a central axis extending along the elongate aerosol-generating device.
