Abstract (en)
[origin: EP3954239A1] A heat-not-burn device, method, and system for tobacco products. The device includes a housing (10) and a heating body (11) and a power supply (14) provided inside the housing (10). The device further includes: an induction unit (12) configured to sense and generate induction signals; and a control circuit (13) electrically connected to the induction unit (12) and the heating body (11), and configured to receive the induction signals and to control, according to the received induction signals, an operating temperature of the heating body (11) to switch among a plurality of temperature intervals, wherein the plurality of temperature intervals at least includes a heat preservation interval and an excitation temperature interval. The heat-not-burn device, method, and system for tobacco products can reduce the heat loss of a heat-not-burn device.
