  • the length of the electric arc is greater than the radial spacing between the first electrode 32 and the second electrode 34, so that a longer electric arc is generated between the axial ends of the first electrode 32 and the second electrode 34, thus increasing the heating region.
  • the atomizer 100 can effectively heat and atomize the aerosol-generating substrate sleeved outside tube body 10.
  • the heat generated by the plasma is used to quickly heat the aerosol-generating substrate, and the high energy density characteristics of plasma heating is utilized to shorten the preheating waiting time, which is convenient for users to use, prevents the aerosol-generating substrate from being scorched due to the long preheating time, and improves the taste after atomization.
  • metal parts such as electrodes do not need to directly contact the aerosol-generating substrate, which can prevent atomized aerosol-generating substrate from being doped by metal substances, thereby further improving the taste after atomization.
