Patent No. EP3883342 (titled "Induction Heating Assembly For A Vapour Generating Device") was filed by Japan Tobacco on Sep 3, 2018. The application was issued on Apr 9, 2025.
Induction heating assembly for a vapour generating device that enables safe and reliable charging of the device while maintaining compact design. The assembly comprises a rechargeable power source and an induction coil that can be used to generate an electromagnetic field for charging the power source. The charging coil is positioned in an external charging device, allowing the charging system to operate independently of the device while maintaining the device's internal space. This design enables the assembly to be used in conjunction with the device, eliminating the need for an internal charging mechanism while still providing the charging functionality.
