Heater and cigarette device with the heater

A heater, comprising:

• a base body, provided with a surface, wherein the base body comprises a first end and a second end opposite to each other, and the surface extends from the first end to the second end;
• an infrared electrothermal coating, comprising a first infrared electrothermal coating and a second infrared electrothermal coating formed spaced apart on the surface, wherein the first infrared electrothermal coating and the second infrared electrothermal coating are configured to independently receive an electric power of a power supply to generate heat and then generate infrared rays, so as to radially heat different parts of an aerosol-forming substrate;
• and
• a conductive element, comprising a first electrode, a second electrode, and a common electrode spaced apart on the base body;
• wherein
• each of the first electrode, the second electrode, and the common electrode comprises a coupling portion and a conductive portion;
• wherein
• the conductive portion of the first electrode is electrically connected to the first infrared electrothermal coating, the conductive portion of the second electrode is electrically connected to the second infrared electrothermal coating, and the conductive portion of the common electrode is electrically connected to the first infrared electrothermal coating and the second infrared electrothermal coating;
• and
• the coupling portion of the first electrode is disposed next to the first end, the coupling portion of the second electrode is disposed next to the second end, the coupling portion of the common electrode is disposed next to a selective one of the first end and the second end, and the coupling portion of the first electrode, the coupling portion of the second electrode, and the coupling portion of the common electrode are configured to couple the power supply to feed the electric power to the infrared electrothermal coating;
• the first infrared electrothermal coating and the second infrared electrothermal coating are spaced apart from each other along a circumferential direction of the base body.
