Aerosol generating device, and heater and control method for aerosol generating device

A heater for an aerosol generating device, comprising:

• a first heating element and a second heating element arranged in sequence along a longitudinal direction;
• and
• a first electrode, a second electrode, and a third electrode, wherein the first heating element is at least partially electrically connected between the first electrode and the second electrode, so as to supply power to the first heating element through the first electrode and the second electrode;
• and the second heating element is at least partially electrically connected between the first electrode and the third electrode, so as to supply power to the second heating element through the first electrode and the third electrode.

A control method for an aerosol generating device, the aerosol generating device comprising:

• a chamber, configured to accommodate an aerosol generating article;
• a first heating element and a second heating element, arranged along a longitudinal direction of the chamber and configured to heat the aerosol generating article;
• and
• a battery core, configured to provide power to the first heating element and the second heating element;
• and
• the method comprising:
• controlling the battery core to separately provide the power to the first heating element during a first time period, so that the first heating element separately performs heating;
• and
• control the battery core to simultaneously provide the power to the first heating element and the second heating element during a second time period, so that the first heating element and the second heating element simultaneously perform heating.
