The infrared electrothermal coating 111 may be coated on the outer surface of the substrate 11, or may be coated on the inner surface of the substrate 11. An infrared electrothermal coating 111 is preferably applied to the outer surface of the substrate 11.

The infrared electrothermal coating 111 can generate heat energy when being electrified, and further generate infrared rays with certain wavelengths, such as: 8-15 μm far infrared ray. When the wavelength of the infrared light matches the absorption wavelength of the aerosol-forming substrate, the energy of the infrared light is readily absorbed by the aerosol-forming substrate. In this example, the wavelength of the infrared ray is not limited, and may be an infrared ray of 0.75 to 1000 μm, preferably a far infrared ray of 1.5 to 400 μm.

Referring to fig. 5, in an example, the conductive module 112 further includes a third conductive portion 1123, the third conductive portion 1123 is disposed on the outer surface of the substrate 11 between the first conductive portion 1121 and the second conductive portion 1122, the third conductive portion 1123 is electrically connected to the infrared electrothermal coating 111, and the third conductive portion 1123 divides the infrared electrothermal coating 111 into two heating regions (indicated by 1111 and 1112 in the figure) along the longitudinal direction of the substrate 11, so as to realize the sectional heating of the aerosol-forming substrate in the chamber.

In this example, the third conductive portion 1123 divides the infrared electro-thermal coating 111 into two heating regions, and segmented heating of the aerosol-forming substrate within the chamber may be achieved by controlling the powering on and off of the first conductive portion 1121, the second conductive portion 1122, and the third conductive portion 1123.

The cantilever 133 has a certain amount of flexibility suitable for receiving the temperature acquisition module 12. The position limiting portion 134 is used for limiting the movement of the temperature acquisition module 12 relative to the bracket 13, and the position limiting portion 134 is configured to allow the temperature acquisition module 12 to contact or approach a target position on the outer surface of the base 11 when the bracket 13 is fixed on the outer surface of the base 11.

In this example, the limiting portion 134 has an opening 1341, and the opening 1341 is used for leading out a lead (not shown in the drawings) electrically connected with the temperature acquisition module 12 to the outer side 131.

As an example, two protrusions 1342 protruding in opposite directions may be provided at the opening 1341 such that the size of the opening 1341 is smaller than the size of the temperature acquisition module 12, and the temperature acquisition module 12 is prevented from being removed from the opening 1341 by the protrusions 1342.

The side wall of the limiting portion 134 has at least one protrusion, which is suitable for preventing the temperature collection module 12 from falling off after the temperature collection module 12 is accommodated in the limiting portion 134. For example, two side walls of the limiting portion 134 may be respectively provided with a buckle 1343, and the buckle 1343 may prevent the temperature acquisition module 12 from falling off.

Referring again to fig. 7-8, the upper end of the bracket 13 has a pair of extension arms 135, and the extension arms 135 have a shape adapted to the outer surface of the base 11, so that the base 11 can be snapped into the extension arms 135 to fix the bracket 13 on the outer surface of the base 11. Wherein the end of the extension arm 135 has a protrusion extending toward the outer surface of the base 11 to provide an additional fastening force by using the flexible deformation of the extension arm 135.

The outer side 131 of the bracket 13 is further provided with a lead clamping groove 138, and the lead clamping groove 138 is used for fixing a lead electrically connected with the electrode of the substrate 11 and/or a lead electrically connected with the temperature acquisition module 12.
