[0039] See also Figure 1 and Figure 2 The embodiment of the present application provides a heating plate tube 1, which has a plurality of heating parts 12 arranged in sequence; an isolation tube 22, the heating plate tube 1 is sleeved in the isolation tube 22, and the isolation tube 22 includes a plurality of isolation parts 221 arranged in sequence, each isolation part 221 is arranged corresponding to a heating part 12, and adjacent isolation parts 221 are arranged at intervals to reduce heat transfer between the isolation parts 221.
[0040] By providing a plurality of heating parts 12 and making each heating part 12 heat a different area, the heating sheet tube 1 can heat the non-uniform smoke-generating medium at multiple sections and different temperatures at the same time, thereby solving the problem of poor heating effect of the electronic cigarette. In addition, by providing a corresponding isolation part 221 for each heating part 12 and making adjacent isolation parts 221 spaced apart, the thermal resistance between the isolation parts 221 can be increased, thereby reducing the heat exchange between the isolation parts 221, which is beneficial for the electronic cigarette to control the temperature of the area corresponding to each heating part 121.

By making the length of the sealing portion 213 equal to the circumference of the heating film tube 1, the sealing portion 213 can wrap around the heating film tube 1 again on the basis of the bearing portion 212, which is beneficial to reduce the occurrence of the bearing portion 212 falling off the heating film tube 1.
