The present invention has no particular limitation on the preparation method of the heated cigarette, and can be prepared by the preparation method of the heated cigarette well known to those skilled in the art.

In the present invention, the reconstituted tobacco leaves of the inner layer (closer to the heat source tobacco leaf layer) and the outer layer (far away from the heat source tobacco leaf layer) of the cartridge use food additives and atomizer formulations with different flavors, and the inner layer of the reconstituted tobacco leaves is selected for atomization with a high proportion of propylene glycol. Compared with pure glycerin, the atomizer with a high proportion of propylene glycol requires a lower temperature for release, and there is a synergistic effect with the tobacco raw material, which can promote the release of smoke at a lower temperature; when the heated cigarette cartridge is heated When the stick is inserted in the center of the cartridge, the inner layer of cartridge will heat up first, and the smoke will be released first. In this way, the smoke of the inner layer of reconstituted tobacco leaves can be released first; The temperature required for release is relatively high, and the synergy with the tobacco raw material is weak, and the flue gas can be effectively released at a relatively high temperature. Due to the limitation of the heat transfer rate, the reconstituted tobacco leaves on the outer layer of the cartridge heat up slowly and fog If the proportion of the chemical agent propylene glycol is low, the release of smoke will be delayed.

The raw materials used in the following examples of the present invention are all commercially available commodities.

Performance testing

Use the puff-by-puff release characteristics of key components in the smoke of the cartridges (heated cigarettes) prepared by the embodiment under the ISO smoking mode, and the smoke components are tested by a GC equipped with a TCD detector, and the detection method refers to YQ-ELT 2— 2017 standard; the measured changes in the content of the characteristic taste substances menthol and tea polyphenols are shown in Figures 2 to 4, Figure 2 is the change diagram of the characteristic taste substances of the cartridge prepared in Example 1, and Figure 3 is prepared in Example 2 Figure 4 is a change diagram of the characteristic taste substances of the cartridges prepared in Example 3; it can be seen from Figures 2 to 4 that there are significant differences between menthol and tea polyphenols in the smoke released one by one. , the first 6 mouthfuls mainly show a mint flavor, and then mainly show a tea flavor.

In the present invention, the higher the content of propylene glycol in the reconstituted tobacco atomizer, the lower the release temperature of the atomizer, and there is a synergistic effect with the tobacco, which reduces the temperature required for the release of the aroma substances in the tobacco, which is beneficial to the lower temperature of the flue gas. release. During the smoking process, the reconstituted tobacco leaves with high propylene glycol content will release smoke earlier than the reconstituted tobacco leaves with low propylene glycol content as the temperature of the cartridge increases. The heating rate of the tobacco leaves is also higher than that of the reconstituted tobacco leaves from the outside (located away from the heat source), which is also beneficial to the early release of smoke from the internal reconstituted tobacco leaves, so the flavor of the internal reconstituted tobacco leaves can be released in advance.

The effect achieved by the present invention is that the reconstituted tobacco leaves at the central position of the cartridge (closer to the heat source) release smoke first, and the reconstituted tobacco leaves at the outer position (a position far from the heat source) release the smoke, and with different flavor additives, a multi-flavor cartridge with clear layers is finally realized. The heating cartridge preparation method provided by the invention is simple, convenient to operate, obvious effect and low cost.
