Two electrical connection parts 1112 are disposed at two ends of the main part 1111 respectively, the atomization assembly 1 comprises two electrodes 16, side walls of the first parts 161 of the two electrodes 16 are in contact with the two electrical connection part 1112 respectively, and the heating assembly 11 is sandwiched between the two electrodes 16.
Preferably, an electrode connection hole 131 which allows the electrode 16 to be inserted therein and corresponds to the electrode hole 141 is longitudinally formed in the cover 13.
