Aerosol-generating device with temperature-controlled power converter for heating
The patent application (Publication Number: US20230309624A1) describes an aerosol-generating device that utilizes an induction heating method to heat a susceptor included in an aerosol-generating substrate. The device includes a battery for supplying direct current (DC) power, a power converter to convert the DC power into alternating current (AC) power, and a coil wound along the accommodation space of the device. The coil applies an alternating magnetic field to the susceptor, heating it according to the AC power.
A controller is included in the device to control the time to supply current to the coil, ensuring that the temperature of the susceptor reaches a preset target temperature. The controller can also control the time to supply current based on the target temperature, with a fixed duty of the current. The first duty is preset to be 50%.
The device further includes a capacitor element connected in series or parallel to the coil, which is inductively coupled to the susceptor. The frequency of the current supplied to the coil is set based on the resonance frequencies of the coil and the capacitor element. The frequency is set to be higher than the resonance frequencies by a preset magnitude.
The coil used in the device is a solenoid wound along the accommodation space and can be made of materials such as copper, silver, gold, aluminum, tungsten, zinc, or nickel. The battery included in the device is specifically lithium iron phosphate.
Additionally, the device includes an interface unit with a port for exchanging data with an external device or receiving power from an external source.
In summary, the patent application describes an aerosol-generating device that utilizes induction heating to heat a susceptor in an aerosol-generating substrate. The device includes a battery, power converter, coil, and controller to control the heating process. It also includes a capacitor element, specific materials for the coil, and an interface unit for data exchange or power reception.
