AXIAL HALF-PARTITIONED HEATING TUBE, ELECTRONIC ATOMIZATION DEVICE AND HEATING METHOD

The present invention relates to the technical field of heating, and in particular to an axial half-partitioned heating tube, an electronic atomization device including same, and a heating method. The heating tube includes: a heating base tube (1); and a first heating resistance layer (2), a second heating resistance layer (3), and a third heating resistance layer (4), which are arranged on the heating base tube (1), wherein the first heating resistance layer (2) is arranged in a lower section, and the second heating resistance layer (3) and the third heating resistance layer (4) are arranged side by side in an upper section. The heating tube supplies power to heat the first heating resistance layer (2) and the second heating resistance layer (3) when the atomization device is pre-heated and during the first half of vaping, and at this time, the cigarette that is in contact with the heating tube can be rapidly heated to reach a temperature at which the cigarette can be vaped; and during the second half of vap
