Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette cartridges, and in particular relates to a heated cigarette cartridge and an application thereof, specifically a heated cigarette cartridge with multiple flavors. Background Art

[0002] Heated cigarette cartridges are made from reconstituted tobacco leaves and generally have only one flavor. Even if reconstituted tobacco leaves of different flavors are used to make cartridges, during the smoking process, the entire cartridge is heated at the same time, causing the reconstituted tobacco leaves of different flavors to release smoke at the same time, making it impossible to obtain a taste with obvious levels of distinction. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a heated cigarette cartridge and an application thereof. The heated cigarette cartridge provided by the present invention has multiple flavors with distinct layers.

[0004] The present invention provides a heating cigarette cartridge, comprising:

[0005] Two or more layers of tobacco leaves;

[0006] The smoke release temperature of the tobacco layer close to the heat source is lower than the smoke release temperature of the tobacco layer far from the heat source.

[0007] Preferably, the smoke release time of the tobacco layer close to the heat source is earlier than the smoke release time of the tobacco layer far from the heat source.

[0008] Preferably, each tobacco leaf layer has a different taste.

[0009] Preferably, each tobacco leaf layer independently comprises:

[0010] Tobacco materials, food additives and aerosols;

[0011] The composition of food additives and atomizers in each tobacco leaf layer is different.

[0012] Preferably, the atomizer comprises:

[0013] Glycerin and propylene glycol;

[0014] The food additives include ingredients with different flavors, which are selected from plant extracts, preferably selected from one or more of fruit extracts, tea extracts, coffee extracts, and mint extracts.

[0015] Preferably, the mass ratio of propylene glycol to glycerol in each tobacco leaf layer is different.

[0016] Preferably, the mass ratio of propylene glycol to glycerol in the atomizer in the tobacco leaf layer close to the heat source is higher than the mass ratio of propylene glycol to glycerol in the atomizer in the tobacco leaf layer far from the heat source.

[0017] Preferably, the mass content of propylene glycol in the atomizer of the tobacco leaf layer close to the heat source is ≥30%;

[0018] The mass content of propylene glycol in the atomizer of the tobacco leaf layer far away from the heat source is less than 30%.

[0019] Preferably, the heat source for heating the cigarette cartridge is arranged at the center of the cigarette cartridge to transfer heat to the outside of the cigarette cartridge; or;

[0020] The heat source for heating the cigarette cartridge is externally surrounding and transfers heat to the center of the cigarette cartridge.

[0021] The present invention provides a heated cigarette, comprising:

[0022] The heated cigarette cartridge described in the above technical solution.

[0023] Based on the smoke release characteristics of the heated cigarette cartridge during heating, the present invention couples the temperature field distribution characteristics of the heated cartridge and the action mechanism of the atomizer, arranges the reconstituted tobacco leaves of different flavor formulas in layers to make the cartridge, and uses different atomizer formulas to enable the cartridge to gradually release smoke of different flavors during inhalation. The flavor of the reconstituted tobacco leaves in the inner layer (close to the heat source) of the heated cigarette cartridge prepared by the present invention is released first, and the flavor of the reconstituted tobacco leaves in the outer layer (far away from the heat source) is released later, showing a distinct layer of smoke with multiple flavors.

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides a heating cigarette cartridge, comprising:

[0030] Two or more layers of tobacco leaves;

[0031] The smoke release temperature of the tobacco layer close to the heat source is lower than the smoke release temperature of the tobacco layer far from the heat source.

[0032] In the present invention, it is preferred that the smoke release time of the tobacco layer close to the heat source is earlier than the smoke release time of the tobacco layer far from the heat source.

[0033] In the present invention, it is preferred that each tobacco leaf layer has a different taste.

[0034] In the present invention, each tobacco leaf layer preferably independently comprises:

[0035] Tobacco materials, food additives and aerosol agents.

[0036] In the present invention, it is preferred that the ingredients of food additives in each tobacco layer are different, so that each tobacco layer has a different taste; it is preferred that the atomizer ingredients and the masses of each ingredient in each tobacco layer are different, so that the smoke of different tobacco layers is released sequentially during the heating process.

[0037] In the present invention, the food additive is preferably selected from plant extracts, preferably selected from one or more of fruit extracts, tea extracts, coffee extracts, and mint extracts, such as grape extracts.

[0038] In the present invention, the atomizer preferably includes:

[0039] Glycerin and propylene glycol.

[0040] In the present invention, the mass ratio of the tobacco material, food additive and atomizer is preferably (10-20): (0.5-1.5): (2-6), more preferably (12-18): (0.8-1.2): (3-5), and most preferably (12-13): 1:4.

[0041] In the present invention, the mass ratio of propylene glycol and glycerol in the atomizer in each tobacco layer is preferably different; the mass ratio of propylene glycol and glycerol in the atomizer in the tobacco layer close to the heat source is preferably higher than the mass ratio of propylene glycol and glycerol in the atomizer in the tobacco layer far from the heat source.

[0042] In the present invention, the mass ratio of propylene glycol and glycerin in the atomizer in the tobacco layer close to the heat source is higher than that in the tobacco layer far from the heat source. The higher propylene glycol content in the atomizer can make the smoke in the tobacco layer close to the heat source be released at a lower temperature, and the smoke in the tobacco layer far from the heat source be released at a higher temperature, thereby delaying the release of smoke in the tobacco layer far from the heat source, and the taste of the reconstituted tobacco in the tobacco layer close to the heat source is released first, and the taste of the reconstituted tobacco in the tobacco layer far from the heat source is released later, showing as smoke with distinct layers and multiple flavors.

[0043] In the present invention, it is preferred that the mass of each tobacco leaf layer is the same, the mass content of the atomizer in each tobacco leaf layer is the same; and the mass content of the tobacco material in each tobacco leaf layer is the same.

[0044] In the present invention, the mass content of propylene glycol in the atomizer of the tobacco layer close to the heat source is preferably ≥30%, more preferably 40-70%, more preferably 50-60%, and most preferably 55%; the mass content of propylene glycol in the atomizer of the tobacco layer far from the heat source is <30%, more preferably 10-20%, and more preferably 15%.

[0045] In the present invention, the heat source for heating the cigarette cartridge is preferably arranged at the center of the cigarette cartridge to transfer heat to the outside of the cigarette cartridge; or;

[0046] The heat source for heating the cigarette cartridge is externally surrounding and transfers heat to the center of the cigarette cartridge.

[0047] In the present invention, when the heat source of the heating cartridge is set at the center of the cartridge, the inner tobacco layer is the tobacco layer close to the heat source, and the outer tobacco layer is the tobacco layer far away from the heat source; when the heat source of the heating cartridge is externally surrounded, the outer tobacco layer is the tobacco layer close to the heat source, and the inner tobacco layer is the tobacco layer far away from the heat source.

[0048] In the present invention, the heated tobacco cartridge can be composed of two layers, an inner tobacco layer and an outer tobacco layer, of different flavors, or can be composed of multiple tobacco layers of different flavors to form tobacco cartridges with more layers of flavors. The setting principle of the multiple tobacco layers is similar. The tobacco cartridge is heated by a heat source of a smoking device used in conjunction with the tobacco cartridge, and the mass of propylene glycol in the tobacco layer is controlled according to the position of the tobacco layer and the heat source, so that the temperature and time of smoke release from different tobacco layers are different; the method for setting the propylene glycol content in the inner and outer tobacco layers when the heat source is at the center of the tobacco cartridge is opposite to the method for setting the propylene glycol content in the heat source that surrounds the outside of the tobacco cartridge.

[0049] The present invention has no particular limitation on the method for preparing the heated cigarette cartridge, and the heated cigarette cartridge can be prepared by a method well known to those skilled in the art. In the present invention, the method for preparing the heated cigarette cartridge preferably includes:

[0050] mixing tobacco material, food additives and atomizer to obtain a mixture;

[0051] preparing the mixture to obtain reconstituted tobacco leaves;

[0052] The reconstituted tobacco leaves are used to prepare heated tobacco cartridges.

[0053] In the present invention, the components and mass ratios of the tobacco material, food additives and atomizer are consistent with those described in the above technical solution.

[0054] In the present invention, the method for preparing the mixture into reconstituted tobacco is preferably a papermaking method, a thick pulp method, a roller pressing method, etc.

[0055] In the present invention, the reconstituted tobacco is preferably rolled to prepare a heated cigarette cartridge; preferably, a multi-layer reconstituted tobacco is prepared, and the multi-layer reconstituted tobacco is rolled to obtain a heated cigarette cartridge, and the mass ratio of the multi-layer reconstituted tobacco is preferably 1:1.

[0056] The present invention provides a heated cigarette, comprising:

[0057] The heated cigarette cartridge described in the above technical solution.

[0058] In the present invention, the heating cartridge is preferably cylindrical.

[0059] In the present invention, the heated cigarette preferably further includes: a filter.

[0060] In the present invention, the filter is preferably cylindrical and is preferably arranged at one end of the heating cartridge.

[0061] In an embodiment of the present invention, the structural schematic diagram of the heated cigarette is as follows Figure 1 shown.

[0062] The present invention has no particular limitation on the preparation method of the heated cigarette, and the heated cigarette can be prepared by a preparation method of heated cigarettes well known to those skilled in the art.

[0063] In the present invention, the reconstituted tobacco of the inner layer (the tobacco layer close to the heat source) and the outer layer (the tobacco layer far away from the heat source) of the cigarette cartridge use food additives and atomizer formulas of different flavors. The inner layer of the reconstituted tobacco uses an atomizer with a high propylene glycol ratio. The atomizer with a high propylene glycol ratio requires a lower temperature for release than the pure glycerin atomizer, and has a synergistic effect with the tobacco raw materials, which can promote the release of smoke at a lower temperature; when the heating rod of the heated cigarette cartridge is inserted into the center of the cartridge, the inner layer of the cigarette cartridge heats up first and releases smoke first. In this way, the smoke of the inner layer of the reconstituted tobacco can be released first; the outer layer of the reconstituted tobacco uses an atomizer with a low propylene glycol ratio. The temperature required for smoke release is higher, and the synergistic effect with the tobacco raw materials is weak. The smoke can only be effectively released at a higher temperature. Due to the limitation of the heat transfer rate, the reconstituted tobacco of the outer layer of the cigarette cartridge heats up slowly and the atomizer has a low propylene glycol ratio, so the smoke release will be delayed.

[0064] The raw materials used in the following examples of the present invention are all commercially available products.

[0065] Example 1

[0066] Tobacco materials, food additives and atomizers are mixed in a mass ratio of 12:1:4, and reconstituted tobacco leaves are prepared by a papermaking method; wherein, the food additive used for the outer layer of reconstituted tobacco leaves is tea extract, and the atomizer is 40wt% propylene glycol and 60wt% glycerol; the food additive used for the inner layer of reconstituted tobacco leaves is mint extract, and the atomizer is 10wt% propylene glycol and 90wt% glycerol; the two layers of reconstituted tobacco leaves are rolled into a cigarette cartridge in a mass ratio of 1:1, and used in conjunction with a central heating device.

[0067] Example 2

[0068] Tobacco materials, food additives and atomizers are mixed in a mass ratio of 18:1:6, and reconstituted tobacco leaves are prepared by a thick slurry method; the food additive used for the outer layer of reconstituted tobacco leaves is tea extract, and the atomizer is 35wt% propylene glycol and 65wt% glycerol; the food additive used for the inner layer of reconstituted tobacco leaves is mint extract, and the atomizer is 15wt% propylene glycol and 85wt% glycerol; the two layers of reconstituted tobacco leaves are rolled into a cigarette cartridge in a mass ratio of 1:1, and used in conjunction with a central heating device.

[0069] Example 3

[0070] Tobacco materials, food additives and atomizers are mixed in a mass ratio of 10:1:3, and reconstituted tobacco leaves are prepared by a rolling method; wherein, the food additive used for the outer layer of reconstituted tobacco leaves is tea extract, and the atomizer is 45wt% propylene glycol and 55wt% glycerol; the food additive used for the inner layer of reconstituted tobacco leaves is mint extract, and the atomizer is 20wt% propylene glycol and 80wt% glycerol; the two layers of reconstituted tobacco leaves are rolled into a cigarette cartridge in a mass ratio of 1:1, and used in conjunction with a central heating device.

[0071] Performance Testing

[0072] The puff-by-puff release characteristics of key components in the smoke of the cigarette cartridge (heated cigarette) prepared in the embodiment under ISO smoking mode, the smoke components are tested using a GC equipped with a TCD detector, and the detection method refers to the YQ-ELT 2-2017 standard; the changes in the measured characteristic taste substances menthol and tea polyphenols are as follows Figure 2 to Figure 4 As shown, Figure 2 This is a graph showing the change in characteristic flavor substances of the cigarette cartridge prepared in Example 1. Figure 3 This is a graph showing the changes in the characteristic flavor substances of the cigarette cartridge prepared in Example 2. Figure 4 This is a graph showing the characteristic flavor substance changes of the cigarette cartridge prepared in Example 3; Figure 2 to Figure 4 It can be seen that there are significant differences in menthol and tea polyphenols in the smoke released puff by puff. The first 6 puffs mainly show mint flavor, and then mainly show tea flavor.

[0073] In the present invention, the higher the propylene glycol content in the reconstituted tobacco atomizer, the lower the atomizer release temperature, and there is a synergistic effect between the atomizer and the tobacco, which reduces the temperature required for the release of flavor substances in the tobacco, and is conducive to the release of smoke at a lower temperature. During the smoking process, the reconstituted tobacco with a high propylene glycol content will release smoke before the reconstituted tobacco with a low propylene glycol content as the temperature of the cigarette cartridge increases, and due to the existence of the thermal resistance of the cigarette cartridge itself, the heating rate of the reconstituted tobacco inside (near the heat source position) is also higher than that of the reconstituted tobacco outside (far away from the heat source position), which is also beneficial to the internal reconstituted tobacco to release smoke in advance, so the taste of the internal reconstituted tobacco can be released in advance.

[0074] The effect achieved by the present invention is that the reconstituted tobacco leaves at the center of the cigarette cartridge (close to the heat source) release smoke first, and the reconstituted tobacco leaves at the outer position (far away from the heat source) release smoke later, and with different flavor additives, a multi-flavor cigarette cartridge with clear layers is finally achieved. The preparation method of the heated cigarette cartridge provided by the present invention is simple, easy to operate, has obvious effects, and is low in cost.
