AI Technical Summary
Existing electromagnetic induction heated cigarettes have low temperature detection accuracy, making it impossible to achieve real-time, active, precise temperature measurement and closed-loop control.
By employing heating coils and information coils with different operating frequencies, and utilizing magnetic fields as a dual carrier of energy and information, heating and temperature measurement are achieved in a non-contact manner. The information coil detects electrical parameter signals for temperature feedback and power supply adjustment.
It achieves real-time, accurate, and highly stable non-contact collaborative operation of heating and temperature detection, reduces magnetic field interference, and ensures the accuracy and stability of temperature control.
