Abstract (en)

[origin: EP4029387A1] Embodiments provide a heater and an electric heating system using the same. In the embodiments, the heater includes a heating element for heating tobacco products to generate aerosol, and a plurality of heating resistors are arranged at intervals on the heating element The two ends of each of the heating resistors are respectively connected to the electrode part, and the free end of the electrode part is used to connect the heat source part; wherein, a plurality of the heating resistors operate sequentially or together to generate heat. The electrical heating system of the present disclosure includes a heater receiving part containing the heater for heating the tobacco product to generate the aerosol. The present disclosure can improve the overall heating speed of the heating element and improve the heating uniformity.
