In addition, the resistance temperature coefficient of at least one section of the plurality of sections of heating wires 11 is greater than the resistance temperature coefficients of the other sections of heating wires 11. In some embodiments, when the number of the heating wires 11 in the heat generating body 10 is more than three, the temperature coefficient of resistance of one of the heating wires 11 is larger than that of the other heating wires 11, and the temperature coefficient of resistance of the other heating wires 11 is less than or equal to 10^ -6 ppm/DEG C.
Wherein, the Temperature Coefficient of Resistance (TCR) represents the relative change of resistance value when the temperature changes by 1 degree centigrade, and the unit is ppm/DEG C.
Because the resistance temperature coefficient of the heater 11 of interlude is greater than the heater 11 at both ends, and the heater 11 resistance temperature coefficient at both ends is less, therefore, when testing the holistic resistance of heat-generating body 10 through the TCR, the resistance change that mainly tests is the resistance change of interlude heater 11, and the heater 11 resistance temperature coefficient at both ends is little, therefore the influence factor is also little, thereby can reduce the temperature difference that each section resistance change of heat-generating body 10 arouses, finally make the heat-generating body 10 temperature that measures more accurate, because the heat-generating body 10 temperature that measures is more accurate, therefore, smoke generating device is when opening every time, can control the heating temperature of heat-generating body 10 more even, thereby guarantee that the taste that smoke generating device suction was experienced every time is unanimous.

The first end 11a is the left end of the first heating wire 111, and the second end 11b is the right end of the second heating wire 112. Of course, the first end 11a may be a right end of the first heating wire 111, and the second end 11b may be a left end of the first heating wire 111.
