In some embodiments, the aerosol generating article 100 further comprises a cooling portion 140. The cooling portion 140 is located between the atomizing portion 120 and the nozzle 130, and is used for cooling the aerosol generated by the atomizing portion 120.

Referring to fig. 3 and 4, in some embodiments, the atomizing part 120 is further provided with an airflow channel, and the airflow channel penetrates through the atomizing part 120. In one embodiment, the airflow channel is located on the central axis of the atomizing area 120. It is understood that, in other embodiments, the position of the airflow channel is not limited to the above, and may be other positions as long as external air (e.g. air) can enter the atomizing area 120 and flow out the aerosol formed by the atomizing area 120. Of course, the atomizing area 120 may not have an airflow channel, and in this case, the aerosol generated by the atomizing area 120 may flow to the nozzle 130 through another path (for example, the embodiment shown in fig. 2 and 5).

In some embodiments, the aerosol-generating article 100 further comprises an electrode structure for electrically connecting the aerosolizing portion 120 to the power source 210. Specifically, the electrode structure includes a first electrode 150 and a second electrode 160 spaced apart from the first electrode 150. More specifically, one end of the first electrode 150 directly contacts the atomizing area 120 (e.g., is located in the atomizing area 120 or on an end surface of the atomizing area 120), and the other end protrudes from the atomizing area 120; one end of the second electrode 160 is also in direct contact with the atomizing area 120 (e.g., on the atomizing area 120 or an end surface of the atomizing area 120), and the other end protrudes from the atomizing area 120.

In some embodiments, the first electrode 150 and the second electrode 160 are located on both end faces of the atomizing area 120.

When the external air flows through the end surface of the atomizing area 120 close to the first electrode 150 without passing through the atomizing area 120, the first electrode 150 should be provided with a through hole through which the aerosol flows out. In other embodiments, the first electrode 150 and the second electrode 160 are located on the sides of the atomizing area 120. It is understood that in some embodiments, the aerosol-generating article 100 does not include an electrode structure. At this time, the atomization part 120 is electrically connected to the power supply 210 by being in direct contact with the electrical connection of the electronic atomizer 200.

In some embodiments, the cladding layer 110 is a conductive cladding layer 110. Specifically, the material of the coating layer 110 is selected from at least one of conductive metal simple substance (e.g., aluminum foil, copper foil, etc.), conductive mica, graphite, conductive alloy, silicon carbide, conductive fiber, and conductive resin. It is understood that when the coating layer 110 is a conductive coating layer 110, the coating layer 110 can serve as an electrode structure of the aerosol raw product 100 for electrically connecting with the power source 210, and in this case, it is not necessary to provide an additional electrode structure on the atomizing area 120 or an electrode structure on the electronic atomizer 200. Of course, in this case, only the atomizing area 120 is packed in the coating layer 110 for safety. It is understood that the cover 110 may also serve as a packaging layer for the aerosol-forming product 100 to wrap other components of the aerosol-forming product 100, if other security measures are present at this time.

The aerosol-produced product 100 can be stably located in the accommodation chamber 221 by the pressing force between the first electrode 150 and the third electrode 230. In an alternative specific example, the first electrode 150 is a rigid electrode, the third electrode 230 is an elastic electrode, when the aerosol raw product 100 is installed in the accommodating cavity 221, the first electrode 150 presses the third electrode 230, so that the third electrode 230 is compressed, and the first electrode 150 is clamped in the accommodating cavity 221 by the pressing force from the third electrode 230, so that the aerosol raw product 100 can be installed in the accommodating cavity 221 more stably, and the electrical connection between the first electrode 150 and the third electrode 230 is more reliable. In another alternative embodiment, the first electrode 150 is an elastic electrode and the third electrode 230 is a rigid electrode.

In some embodiments, the second electrode 160 or the fourth electrode 240 is an elastic electrode, and a compressive force exists between the second electrode 160 and the fourth electrode 240 after the aerosol-generating article 100 is mounted in the accommodating cavity 221.

In an alternative specific example, the second electrode 160 is a rigid electrode, the fourth electrode 240 is an elastic electrode, and when the aerosol raw product 100 is installed in the accommodating cavity 221, the third electrode 230 presses the fourth electrode 240, so that the fourth electrode 240 is compressed, so that the fourth electrode 240 receives the pressing force from the second electrode 160, and thus the aerosol raw product 100 can be installed in the accommodating cavity 221 more stably, and the electrical connection of the second electrode 160 or the fourth electrode 240 is more reliable. In another alternative specific example, the second electrode 160 is an elastic electrode and the third electrode 230 is a rigid electrode.

That is, the first electrode 150 is detachably and electrically connected to the third electrode 230; the second electrode 160 is detachably and electrically connected to the fourth electrode 240. At this time, after the aerosol production product 100 is consumed, the aerosol production product 100 may be replaced with a new one, and the electronic atomizer 200 continues to atomize the aerosol. That is, the atomization system 10 is not disposable, and the electronic atomizer 200 can be reused. It is to be appreciated that in some embodiments, the electronic atomizer 200 is non-removably connected to the aerosol generating article 100. That is, the aerosol-generating article 100 is fixed in the accommodating chamber 221 of the electronic atomizer 200. The first electrode 150 is non-detachably electrically connected (e.g., welded) to the third electrode 230, and the second electrode 160 is non-detachably electrically connected (e.g., welded) to the fourth electrode 240.
