Description

A SYSTEM AND A METHOD TO CHARGE AN AEROSOL GENERATING DEVICETECHNICAL FIELD

[0001] The present disclosure relates to the field of aerosol generating devices. More particularly, the present disclosure relates to a system and a method to charge an aerosol generating device, ensuring safe and more reliable charging experience to a user.BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] Existing aerosol generating devices are rechargeable devices with aerosol generating substrate filled cartridges to be used once. Charging of these devices can be done by either micro- Universal Serial Bus (USB) port or C-type systems. However, usage of such ports poses threat to these devices as any readily available charging systems connected to the devices lead to safety problems of the devices which may lead to failure of such devices. In order to address the said issue, various other types of charging unit have been developed with varying internal designs.

[0004] A patent document WO2022101454A1 entitled, “Aerosol-generating system with improved electrical connector” describes an electrically operated aerosol generating system comprising an aerosol-generating device, and a charging unit configured to receive the aerosol generating device, a first connector part, and a second connector part. The aerosol-generating device having one of the first connector part and the second connector part. Further, the charging unit having the other one of the first connector part and the second connector part. In the referred document, the charging unit comprises more than two electrical contacts on a planar surface.

[0005] Another patent document W02018202730A1 entitled, “Aerosol-generating system with electrical connector” describes an electrically operated aerosol-generating system comprising an aerosol-generating device, and a charging unit configured to receive the aerosol-generating device, and a first connector part and a second connector part. The aerosol-generating device has the first connector part and the charging unit has the second connector part. The first connector part comprises three electrical contacts andcorrespondingly the second connector part comprises three electrical contacts that any of the electrical contacts will be in contact with the corresponding contacts of the first connector part. In the referred documents, use of three electrical contacts may involve additional casting cost and require more space to accommodate the electrical contacts.

[0006] Moreover, some of the existing aerosol generating devices have a rechargeable battery in the charging unit to recharge the aerosol generating device. Further, charging pins of the existing devices come with a built-in charger circuit in a control unit that charges the battery using a standard charger. However, due to compact size of the aerosol generating device, creating space for a Printed Circuit Board (PCB) control unit may be challenging, and also removing the heat generated by the PCB control circuit may be tricky.

[0007] Thus, there arises a need for modification in design of the charging device as well as in the aerosol generating device to address the above said issues.

[0008] There is therefore a need in the art to develop a cost effective, safe and portable system and a method to charge an aerosol generating device, ensuring safe and more reliable charging experience to a user.OBJECTS OF THE PRESENT DISCLOSURE

In an embodiment, the body 200 of the aerosol generating device 102 without the cartridge 210, can be used for charging.

[0063] In an embodiment, the system 100 includes a control unit 110 positioned within the aerosol generating device 102, and configured to receive the electric power from the charging assembly 400. The aerosol generating device 102 can include a first set of engagement structures 206 such as 206-1, 206-2 positioned at the terminating end 200a of the body 200 of the aerosol generating device 102.

The energy source 106 is configured to receive the electric power from the control unit 110 through the polarity converter 104, and supply the received electric power to one or more electronic components of the aerosol generating device 102. The polarity converter 104 can be a bridge rectifier configured to correct / convert the polarity of an input voltage or current of the input power supply / the power supply source to the suitable polarity for charging the energy source 106. Therefore, the terminating end 200a of the body 200 of the aerosol generating device 102 can be engaged with the charging assembly 400 in one or more orientations to charge the energy source 106 through the polarity converter 104. The bridge rectifier may be diode-based, Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET)-based, or implemented using any suitable components or configurations, without any limitations.
