Description

Technical Field

[0001] The present application relates to the technical field of aerosol generation, and particularly to an aerosol generating device and an aerosol generating system. Background Art

[0002] An aerosol generating device is a device that can convert liquid or solid substances into aerosol. A heat-not-burn cigarette is a special aerosol generating device. The heating temperature of a heat-not-burn cigarette is usually 200°C to 400°C, which is much lower than the combustion temperature of traditional cigarettes. The harmful components generated by heating are greatly reduced, so it has developed rapidly. In order to simulate the "smoking" effect of traditional cigarettes, a smoke generator needs to be added to the aerosol matrix in the non-tobacco section of the heated cigarette.

[0003] Commonly used smoke generators are glycerol or a mixed solvent containing glycerol, and their mass content is usually 20% to 40%. In order to pursue a stronger smoking effect, the glycerol content will be higher. The high content of glycerol in the aerosol matrix of heat-not-burn cigarettes will penetrate to the outside of the wrapping material layer, resulting in patches, which seriously affects the appearance quality of cigarettes and the experience of consumers.

[0004] Therefore, it is necessary to improve the traditional technology to reduce the problem of smoke generator penetration while obtaining a good atomization effect. Summary of the Utility Model

[0005] Based on this, it is necessary to provide an aerosol generating device and an aerosol generating system, which can reduce the problem of smoke generator penetration while obtaining a good atomization effect.

[0006] In the first aspect of the present application, an aerosol generating device is provided, including a wrapping material layer, a filter body, a hollow device, and an aerosol matrix; the wrapping material layer wraps around the outside of the filter body, the hollow device, and the aerosol matrix connected in sequence; the aerosol matrix includes a tobacco section aerosol matrix and a non-tobacco section aerosol matrix, and the non-tobacco section aerosol matrix includes a porous matrix and a smoke generator, and the smoke generator is adsorbed in the porous matrix.

[0007] In this way, in the above aerosol generating device, the aerosol matrix includes a tobacco section aerosol matrix and a non-tobacco section aerosol matrix. The tobacco section aerosol matrix can provide the satisfaction of tobacco as a tobacco functional section. The non-tobacco section aerosol matrix can adsorb a higher content of smoke generator due to its porous matrix structure and can be used as the main smoke generating functional area. Therefore, the content of the smoke generator in the tobacco section aerosol matrix can be reduced, and the problem of smoke generator penetration can be reduced. In this way, the tobacco section aerosol matrix and the non-tobacco section aerosol matrix play their respective advantages, and can reduce the penetration problem while obtaining a good atomization effect, improving the appearance quality of cigarettes and the experience of consumers.

[0008] In some of these embodiments, the non-tobacco segment aerosol matrix is located at one end of the tobacco segment aerosol matrix close to the hollow device. Compared with the structure where the non-tobacco segment aerosol matrix is located at one end of the tobacco segment aerosol matrix away from the hollow device, when the non-tobacco segment aerosol matrix is located at one end of the tobacco segment aerosol matrix close to the hollow device, the non-tobacco segment aerosol matrix is closer to the filter element, and the utilization rate of the aerosol-forming agent is higher; in addition, the tobacco segment aerosol matrix is located on the outside, which facilitates the heating component to act on the tobacco segment aerosol matrix for heating, and it is cleaner and easier to adjust the product design when compared with the situation where the heating component acts on the non-tobacco segment aerosol matrix for heating.

[0010] In this way, the side wall of the non-tobacco segment aerosol matrix is provided with a through groove, and a channel is formed between the area of the side wall of the non-tobacco segment aerosol matrix where the groove is provided and the wrapping material layer. When the non-tobacco segment aerosol matrix is atomized by heating, the smoke formed by atomization in the central region of the non-tobacco segment aerosol matrix is more likely to diffuse to the groove on this side wall, and at the same time, this through channel also facilitates the transmission of the atomized smoke, thus improving the smoke release efficiency and obtaining a good atomization effect.

[0011] In some of these embodiments, the area of the region of the side wall of the non-tobacco segment aerosol matrix where the groove is provided accounts for 1 / 5 to 4 / 5 of the total area of the side wall of the non-tobacco segment aerosol matrix.

[0012] In some of these embodiments, the area of the region of the side wall of the non-tobacco segment aerosol matrix where the groove is provided accounts for 1 / 4 to 3 / 4 of the total area of the side wall of the non-tobacco segment aerosol matrix.

[0013] In some of these embodiments, the area of the region of the side wall of the non-tobacco segment aerosol matrix where the groove is provided accounts for 1 / 3 to 2 / 3 of the total area of the side wall of the non-tobacco segment aerosol matrix.

[0014] In some of these embodiments, the area of the side wall of the non-tobacco segment aerosol matrix where the groove is not provided is in contact with the wrapping material layer.

[0015] In some of these embodiments, the non-tobacco segment aerosol matrix has a cylindrical structure, and the total arc length of the side wall of the non-tobacco segment aerosol matrix in contact with the wrapping material layer accounts for 1 / 5 to 4 / 5 of the inner total circumference of the wrapping material layer.

[0017] In some embodiments, the number of the grooves on the side wall of the non-tobacco segment aerosol matrix is 1 to 50.

[0018] In some embodiments, in the radial cross-section of the non-tobacco segment aerosol matrix, the total area of the hollowed-out area including the grooves accounts for 5% to 40% of the inner cross-section formed by enclosing the wrapping material layer.

[0019] In some embodiments, a channel is provided inside the non-tobacco segment aerosol matrix, and one end of the channel near the hollow device penetrates through the other end.

[0020] In some embodiments, the number of the channels is 1 to 10.

[0021] In some embodiments, the cross-sectional shape of the channel is a circle, an ellipse, a sector, a polygon, or an irregular shape.

[0022] In some embodiments, based on the volume of the non-tobacco segment aerosol matrix, the total volume ratio of the grooves and the channels is 5% to 40%.

[0023] In some embodiments, one or more of the following conditions are satisfied:

[0044] As described in the background art, increasing the content of the smoke generator can improve the atomization effect, but it will increase the problem of smoke generator penetration. To reduce the penetration phenomenon, one technique is to add an anti-penetration layer in the wrapping material layer, but this increases the cost. Based on this, the present application provides an aerosol generating device, which can obtain a good atomization effect while reducing the problem of smoke generator penetration, and improve the appearance quality of aerosol generating devices such as cigarettes and the experience of consumers.

[0045] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides an aerosol generating device, including a filter body 10, a hollow device 20, an aerosol matrix 30, and a wrapping material layer 40; the wrapping material layer 40 is wrapped around the outside of the filter body 10, the hollow device 20, and the aerosol matrix 30 that are connected in sequence.

[0046] The aerosol matrix 30 includes a tobacco segment aerosol matrix 31 and a non-tobacco segment aerosol matrix 32. The non-tobacco segment aerosol matrix 32 includes a porous matrix and a smoke generator, and the smoke generator is adsorbed in the porous matrix.

[0047] Thus, in the above aerosol generating device, the aerosol matrix 30 includes a tobacco segment aerosol matrix 31 and a non-tobacco segment aerosol matrix 32. The tobacco segment aerosol matrix 31 therein can provide the satisfaction of tobacco as a tobacco functional segment. The non-tobacco segment aerosol matrix 32 can adsorb a higher content of the smoke generator due to its porous matrix structure and can be used as the main smoke generating functional area. Therefore, the content of the smoke generator in the tobacco segment aerosol matrix 31 can be reduced, and its smoke generator penetration problem can be reduced. In this way, the tobacco segment aerosol matrix 31 and the non-tobacco segment aerosol matrix 32 play their respective advantages, and can obtain a good atomization effect while reducing the penetration problem, and improve the appearance quality of aerosol generating devices such as cigarettes and the experience of consumers.

[0048] In some of these embodiments, the non-tobacco segment aerosol matrix 32 is located at one end of the tobacco segment aerosol matrix 31 close to the hollow device 20. In other embodiments, the non-tobacco segment aerosol matrix 32 may also be located at one end of the tobacco segment aerosol matrix 31 away from the hollow device 20. In other words, the non-tobacco segment aerosol matrix 32 and the tobacco segment aerosol matrix 31 may be arranged in any order successively in the extending direction from the filter body 10 to the hollow device 20.

[0049] Compared with the structure where the non-tobacco segment aerosol matrix 32 may also be located at one end of the tobacco segment aerosol matrix 31 away from the hollow device 20, when the non-tobacco segment aerosol matrix 32 is located at one end of the tobacco segment aerosol matrix 31 close to the hollow device 20, the non-tobacco segment aerosol matrix is closer to the filter body, and the utilization rate of the atomizing agent is higher; in addition, the tobacco segment aerosol matrix is located on the outside, which is convenient for the heating component to act on the tobacco segment aerosol matrix to achieve heating, and it is cleaner and easier to adjust the product design when the heating component acts on the non-tobacco segment aerosol matrix to achieve heating.

[0050] In some of these embodiments, the side wall of the non-tobacco segment aerosol matrix 32 is provided with a groove 321, and the groove 321 penetrates from one end of the non-tobacco segment aerosol matrix 32 close to the hollow device 20 to the other end, and a channel is formed between the area of the side wall of the non-tobacco segment aerosol matrix 32 where the groove 321 is provided and the wrapping material layer 40.

[0051] Thus, in the above aerosol generating device, the side wall of the non-tobacco segment aerosol matrix 32 is provided with a penetrating groove 321, and a channel is formed between the area of the side wall of the non-tobacco segment aerosol matrix 32 where the groove 321 is provided and the wrapping material layer 40. When the non-tobacco segment aerosol matrix 32 is heated and atomized, the smoke formed by atomization in the central area close to the non-tobacco segment aerosol matrix 32 is more likely to diffuse to the groove 321 on this side wall, and at the same time, the penetrating channel is also convenient for the transmission of the atomized smoke, so the smoke release efficiency is improved and a good atomization effect is obtained.

[0052] In addition, because a high atomization release efficiency can be obtained, in some examples, the usage amount of the non-tobacco segment aerosol matrix 32 can be reduced, thereby reducing the penetration problem and improving the appearance quality of aerosol generating devices such as cigarettes and the experience of consumers.

[0053] When the non-tobacco segment aerosol matrix 32 is located at one end of the tobacco segment aerosol matrix 31 close to the hollow device 20, further, the hollow device 20 has a hollow part, and the channel formed between the area of the side wall of the non-tobacco segment aerosol matrix 32 where the groove 321 is provided and the wrapping material layer 40 is communicated with the hollow part. Thus, the smoke can be very quickly transmitted to the hollow part of the hollow device 20 from this channel, thereby improving the smoke release efficiency.

[0054] In some of these embodiments, the area of the region on the side wall of the non-tobacco section aerosol matrix 32 where the groove 321 is provided accounts for 1 / 5 to 4 / 5 of the total area of the side wall of the non-tobacco section aerosol matrix 32; as an example, the area ratio can be 1 / 5, 1 / 4, 30%, 1 / 3, 35%, 2 / 5, 1 / 2, 55%, 60%, 2 / 3, 70%, 3 / 4, 4 / 5, or within the range formed by any two of the above point values.

[0055] It can be understood that the total area of the side wall of the non-tobacco section aerosol matrix 32 refers to the area of the side wall of the non-tobacco section aerosol matrix 32 where the groove 321 is not opened; taking the non-tobacco section aerosol matrix 32 as a cylindrical structure as an example in the following text, the total area of the side wall of the non-tobacco section aerosol matrix 32 is based on the side wall area of the non-tobacco section aerosol matrix 32 presented as a cylindrical structure as a whole.

[0056] Furthermore, the area of the region on the side wall of the non-tobacco section aerosol matrix 32 where the groove 321 is provided accounts for 1 / 4 to 3 / 4 of the total area of the side wall of the non-tobacco section aerosol matrix 32.

[0057] Even further, the area of the region on the side wall of the non-tobacco section aerosol matrix 32 where the groove 321 is provided accounts for 1 / 3 to 2 / 3 of the total area of the side wall of the non-tobacco section aerosol matrix 32.

[0058] In some of these embodiments, the region of the side wall of the non-tobacco section aerosol matrix 32 where the groove 321 is not provided is in contact with the wrapping material layer 40. In this way, the region of the side wall of the non-tobacco section aerosol matrix 32 in contact with the wrapping material layer 40 can ensure the heating efficiency of the heating appliance for heating the aerosol generating device, so as to promote the non-tobacco section aerosol matrix 32 to be heated and atomized, generating an atomization effect.

[0059] In some of these embodiments, the non-tobacco section aerosol matrix 32 is a cylindrical structure. Further, the filter body 10 and the hollow device 20 are also cylindrical structures, and the wrapping material layer 40 is enclosed to form a cylindrical structure and is wrapped outside the cylindrical structures of the filter body 10, the hollow device 20, and the non-tobacco section aerosol matrix 32.

[0060] Further, the non-tobacco section aerosol matrix 32 is a cylindrical structure, and the groove 321 penetrates from one end of the non-tobacco section aerosol matrix 32 close to the hollow device 20 to the other end; that is, the groove 321 penetrates from one end to the other end along the axis of the non-tobacco section aerosol matrix 32.

[0061] Furthermore, the groove 321 penetrates through any two cross-sections from one axial end of the non-tobacco segment aerosol matrix 32 to the other end, and the cross-sectional shapes and sizes at these two positions can be the same or different. In a specific example, the cross-sectional shapes of any two positions where the groove 321 penetrates through from one axial end of the non-tobacco segment aerosol matrix 32 to the other end are the same. Further, not only are the cross-sectional shapes the same but they also coincide with each other.

[0062] Furthermore, the total arc length of the side wall of the non-tobacco segment aerosol matrix 32 in contact with the wrapping material layer 40 accounts for 1 / 5 to 4 / 5 of the total inner circumference of the wrapping material layer 40; as an example, this ratio can be 1 / 5, 1 / 4, 30%, 1 / 3, 35%, 2 / 5, 1 / 2, 55%, 60%, 2 / 3, 70%, 3 / 4, 4 / 5, or within the range formed by any two of the above point values. Further, this ratio can be 1 / 4 to 3 / 4, and more preferably 1 / 3 to 2 / 3. Please continue to refer to Figure 2 , the total inner circumference of the wrapping material layer 40 is the same as the outer circumference of the non-tobacco segment aerosol matrix 32 (the circular ring formed by the outermost solid line and the dotted line); the total arc length of the side wall of the non-tobacco segment aerosol matrix 32 in contact with the wrapping material layer 40 is the Figure 2 total length of the outer solid line area in

[0063] In some embodiments, the cross-sectional shape of the groove 321 is a sector, a polygon, or an irregular shape.

[0064] Furthermore, the sector includes a semi-circle, a sector less than 180°, or a sector greater than 180°; the same applies hereinafter.

[0065] Furthermore, the polygon includes, but is not limited to, a triangle, a quadrilateral, a pentagon, a hexagon, etc. The quadrilateral includes, but is not limited to, a square, a rectangle, a trapezoid, a parallelogram, etc. In the example as Figure 2 shown, the cross-sectional shape of the groove 321 is a triangle.

[0066] In some embodiments, the number of grooves 321 on the side wall of the non-tobacco segment aerosol matrix 32 is at least one, for example, 1 to 50, optionally 3 to 30; further optionally 4 to 20, or also within the range formed by any two integers from 1 to 50.

[0067] In some of these embodiments, on any radial cross-section of the non-tobacco segment aerosol matrix 32, the total area of the hollowed-out regions including the grooves 321 accounts for 5% to 40% of the inner cross-section formed by enclosing the wrapping material layer 40. As an example, the area ratio of the channel 322 can be 5%, 8%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, or within the range formed by any two of the above point values as the end values. Further, the area ratio can be 10% to 30%, and is optimized to 15% to 25%.

[0068] In some of these embodiments, a channel 322 is provided inside the non-tobacco segment aerosol matrix 32, which penetrates from one end close to the hollow device 20 to the other end. The channel 322 can also be used for the transmission of the smoke formed by atomization. The smoke agent in the non-tobacco segment aerosol matrix 32 can diffuse both to the outer grooves 321 and to the inner channel 322, thus improving the smoke release efficiency and obtaining a good atomization effect. The setting of the channel 322 is also beneficial to reducing the adsorption of the aerosol released by the tobacco segment aerosol matrix; on the other hand, in some examples, the channel 322 can facilitate the operation of central heating and prevent the heating needle or heating sheet for central heating from hitting the non-tobacco segment aerosol matrix.

[0069] Further, the number of channels 322 inside the non-tobacco segment aerosol matrix 32 is at least one, such as 1 to 10, for example, it can be 1 to 3. Further, at least one channel 322 is located at the axis of the non-tobacco segment aerosol matrix 32.

[0070] In some of these embodiments, the cross-sectional shape of the channel 322 is circular, elliptical, fan-shaped, polygonal or irregular. Further, the polygon includes but is not limited to triangle, quadrilateral, pentagon, hexagon, etc. The quadrilateral includes but is not limited to square, rectangle, trapezoid, parallelogram, etc.

[0071] In some of these embodiments, on the radial cross-section of the non-tobacco segment aerosol matrix 32, the total area of the grooves 321 and the channels 322 accounts for 5% to 40% of the inner cross-section formed by enclosing the wrapping material layer 40; as an example, the area ratio of the channel 322 can be 5%, 8%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, or within the range formed by any two of the above point values as the end values. Further, the area ratio can be 10% to 30%, and is optimized to 15% to 25%.

[0072] In some embodiments, based on the volume of the non-tobacco segment aerosol matrix 32, the total volume of the groove 321 and the channel 322 accounts for 5% to 40%; by way of example, the proportion of the total volume of the groove 321 and the channel 322 can be 5%, 8%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, or within the range formed by any two of the above point values as the end values. Further, the volume proportion can be 30% to 40%. Further, the volume proportion of the channel 322 is 2% to 20%, and the rest is the volume proportion of the groove 321. By way of example, the volume proportion of the channel 322 is 2%, 3%, 5%, 8%, 10%, 12%, 15%, 18%, 20%, or within the range formed by any two of the above point values as the end values.

[0073] Please refer to Figure 3 , in some other embodiments, no channel 322 is provided inside the non-tobacco segment aerosol matrix 32, and it is a solid structure macroscopically.

[0074] In some embodiments, in the direction in which the hollow device 20 extends towards the aerosol matrix 30, the length of the non-tobacco segment aerosol matrix 32 is 2 mm to 15 mm; by way of example, it can be 2 mm, 3 mm, 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, or within the range formed by any two of the above point values as the end values. Further, it can be 3 mm to 12 mm; preferably 5 mm to 10 mm.

[0075] In some embodiments, in the direction in which the hollow device 20 extends towards the aerosol matrix 30, the length of the tobacco segment aerosol matrix 31 is 5 mm to 35 mm; by way of example, it can be 5 mm, 8 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, or within the range formed by any two of the above point values as the end values.

[0076] In some embodiments, a smoke agent is adsorbed in both the tobacco segment aerosol matrix 31 and the non-tobacco segment aerosol matrix 32. The smoke agent is used to produce an atomization effect when heated.

[0077] Traditional aerosol matrices are all based on plant fibers as carriers. Plant fibers include, but are not limited to, plant fibers such as tobacco and wood pulp. However, these plant fibers have a low saturated adsorption capacity for fuming agents such as glycerol. For example, when the mass content of glycerol exceeds 20%, the surface of the aerosol matrix will become wet, which easily leads to penetration and agglomeration. For heat-not-burn cigarettes, taking the fuming agent glycerol as an example, glycerol can evaporate and be released above 150 °C. However, due to the poor thermal conductivity of the aerosol matrix made of plant fiber material, the set temperature of the central heating type heating component is usually about 350 °C, and the set temperature of the circumferential heating type heating component is about 250 °C. Usually, only the heated material close to the heat source can be heated to near the set temperature, while the temperature of the heated material in most areas is much lower than the set temperature range. Therefore, in fact, the efficiency of glycerol release and atomization is not high. The glycerol released and heated in the high-temperature area will be adsorbed and absorbed by the aerosol matrix in the low-temperature area, which also reduces the efficiency of glycerol release and atomization. In addition, too high heating temperature will cause the pyrolysis of glycerol, generating harmful substances such as acetaldehyde and acrolein. Therefore, the present application further improves the structure of the non-tobacco section aerosol matrix 32.

[0078] In some embodiments, the tobacco section aerosol matrix 31 is based on plant fibers as carriers and can be prepared by known processes. Plant fibers include, but are not limited to, plant fibers such as tobacco and wood pulp. Further, the tobacco section aerosol matrix 31, in addition to including a fuming agent, further includes one or more of tobacco leaves, cut tobacco, cut tobacco stems, reconstituted tobacco, tobacco particles, and tobacco extracts. Further, the tobacco section aerosol matrix 31 further includes a flavoring agent, and the flavoring agent includes, but is not limited to, one or more of coffee flavor essence, mint essence, orange flavor essence, strawberry flavor essence, honeydew melon flavor essence, and mango flavor essence. Further, the tobacco section aerosol matrix 31 is in mutual contact with the inner wall of the wrapping material layer 40. Further, the tobacco section aerosol matrix 31 has a cylindrical structure.

[0079] In some of these embodiments, the fuming agent in the non-tobacco section aerosol matrix 32 is adsorbed in the porous material of the porous particle material matrix. Further, the porous material is a porous particle material. In some of these embodiments, the porous matrix in the non-tobacco section aerosol matrix 32 is a porous particle material matrix, and the fuming agent is adsorbed in the porous particle material matrix. This porous particle material matrix is different from the traditional aerosol matrix made of plant fiber material. Since the porous particle material matrix is a porous particle material, it can adsorb a higher content of fuming agent without exudation, thus reducing the penetration problem of fuming agents such as glycerol. Further, the above non-tobacco section aerosol matrix 32 using the porous particle material matrix, combined with the groove 321 structure design of the non-tobacco section aerosol matrix 32, is beneficial to the atomization release efficiency of the fuming agent with a high adsorption amount.

[0080] Further, the porous particulate material matrix is a heat-conducting material. The good heat-conducting performance of the porous particulate material matrix can enhance the heat conduction of the aerosol matrix 32 in the non-tobacco section, improve its heat uniformity, and increase the atomization release efficiency of fuming agents such as glycerol.

[0081] Further, the porous particulate material of the porous particulate material matrix includes at least one of natural porous mineral materials, metal oxides, hydroxides, carbonates, sulfates, activated carbon, and molecular sieves. Further, the natural porous mineral materials include at least one of diatomaceous earth, montmorillonite, sepiolite, and kaolin.

[0082] Further, the average particle size of the porous particulate material is from 200 microns to 600 microns; by way of example, it may be 200 microns, 300 microns, 400 microns, 500 microns, 600 microns, or within the range formed by any two of the above point values as the end values.

[0083] Further, the fuming agents in the tobacco section aerosol matrix 31 and the non-tobacco section aerosol matrix 32 include at least one of glycerol, propylene glycol, ethylene glycol, xylitol, and erythritol. Even further, the fuming agents in the tobacco section aerosol matrix 31 and the non-tobacco section aerosol matrix 32 both include glycerol; further, it may also include at least one of propylene glycol, ethylene glycol, xylitol, and erythritol, such as propylene glycol.

[0084] In some embodiments, based on the total mass of the fuming agents in the non-tobacco section aerosol matrix 32 and the tobacco section aerosol matrix 31, the mass proportion of the fuming agents in the non-tobacco section aerosol matrix 32 is 40% - 65%; by way of example, it may be 40%, 42%, 45%, 48%, 50%, 52%, 55%, 60%, 62.5%, 65%, or within the range formed by any two of the above point values as the end values. Optionally, the mass proportion may be 50% - 60% or 60% - 65%. Within this range, when the total amount of fuming agents added is the same, the release amount and release efficiency of the fuming agents are both relatively high.

[0085] In some embodiments, the mass of glycerol in the non-tobacco section aerosol matrix 32 is from 20 mg / unit to 50 mg / unit; by way of example, it may be 20 mg / unit, 25 mg / unit, 30 mg / unit, 35 mg / unit, 40 mg / unit, 45 mg / unit, 50 mg / unit, or within the range formed by any two of the above point values as the end values.

[0086] In some embodiments, the mass of glycerol in the tobacco section aerosol matrix 31 is from 30 mg / unit to 40 mg / unit. By way of example, it may be 30 mg / unit, 35 mg / unit, 40 mg / unit, or within the range formed by any two of the above point values as the end values.

[0087] In some of these embodiments, the aerosol matrix 32 of the non-tobacco segment may further include one or more of green tea extract, black tea extract, coffee flavor essence, mint essence, orange flavor essence, strawberry flavor essence, cantaloupe flavor essence, and mango flavor essence.

[0088] In some of these embodiments, there may be a spacing between the aerosol matrix 31 of the tobacco segment and the aerosol matrix 32 of the non-tobacco segment, as Figure 1 shown; or they may be directly connected, that is, without a spacing; as Figure 4 shown. Having a certain distance between the two is mainly to avoid the influence of the high content of aerosolizing agent in the aerosol matrix of the non-tobacco segment on the tobacco segment.

[0089] Furthermore, the length of this spacing is 2 mm to 5 mm.

[0090] One embodiment of the present application provides a method for preparing the above-mentioned aerosol generating device, including the following steps:

[0091] Arrange the filter body 10, the hollow device 20, the aerosol matrix 32 of the non-tobacco segment, and the aerosol matrix 31 of the tobacco segment in sequence, and wrap the outside of the filter body 10, the hollow device 20, the aerosol matrix 32 of the non-tobacco segment, and the aerosol matrix 31 of the tobacco segment connected in sequence with the wrapping material layer 40 to obtain the aerosol generating device.

[0092] In some of these embodiments, the preparation of the aerosol matrix 32 of the non-tobacco segment includes the following steps:

[0093] Let the porous material adsorb the aerosolizing agent, and then extrude and mold the porous material adsorbed with the aerosolizing agent to obtain the aerosol matrix 32 of the non-tobacco segment.

[0094] The above method for preparing the aerosol matrix 32 of the non-tobacco segment allows the porous material to first adsorb the aerosolizing agent and then be extruded and molded to form a porous material matrix. In this way, the aerosolizing agent is adsorbed in the porous material of the porous material matrix, enabling the aerosol matrix 32 of the non-tobacco segment to adsorb more aerosolizing agent and not easily leak.

[0095] Understandably, in the process of extrusion molding of the porous material adsorbed with the smoke agent, a binder can be added or not according to the viscosity requirements of the porous material. Some porous materials are viscous by themselves, so the binder can be not added; while some porous materials have low viscosity, and the binder can be added to increase the viscosity and facilitate molding. Further, the binder includes at least one of gum, cellulose binder, polysaccharide, organic acid and conjugate base salt of organic acid, including but not limited to at least one of carboxymethyl cellulose, sodium carboxymethyl cellulose, chitosan, starch, modified starch, polyacrylic acid, sodium silicate. Among them, the most commonly used binder is carboxymethyl cellulose (sodium), and the dosage is 0.5wt% - 2wt%, based on the weight of the porous material adsorbed with the smoke agent; as an example, the dosage ratio of this binder can be 0.5wt%, 0.8wt%, 1wt%, 1.2wt%, 1.5wt%, 2wt%, or within the range formed by any two of the above point values.

[0096] In some embodiments, preparing the non-tobacco segment aerosol matrix 32 includes the following steps: making the porous material adsorb the smoke agent; granulating the porous material adsorbed with the smoke agent; extruding and molding the obtained porous granular material to obtain the non-tobacco segment aerosol matrix 32.

[0097] Further, one of the methods such as impregnation, stirring and mixing, spraying, etc. can be used to make the porous material adsorb the smoke agent. Further, control the adsorption time to reach the saturated adsorption amount.

[0098] Further, before the above-mentioned porous material adsorbs the smoke agent or granulates, it also includes a pretreatment step: crushing the material to an average diameter less than or equal to 80 microns.

[0099] Further, after granulation and before extrusion molding, it also includes processes such as drying, sizing, and sieving the obtained porous granular material in sequence, where the drying temperature is lower than the evaporation temperature of the smoke agent. In this way, porous granular material with an average particle size of 200 microns - 600 microns is prepared.

[0100] Or, in some other embodiments, preparing the non-tobacco segment aerosol matrix 32 includes the following steps: granulating the porous material to obtain porous granular material; then making the porous granular material adsorb the smoke agent, and extruding and molding the porous granular material adsorbed with the smoke agent to obtain the non-tobacco segment aerosol matrix 32.

[0101] Further, one of the methods such as impregnation, stirring and mixing, spraying, etc. can be used to make the porous granular material adsorb the smoke agent. Further, control the adsorption time to reach the saturated adsorption amount.

[0102] Further, after granulating to obtain the porous particulate material and before allowing the porous particulate material to adsorb the smoke agent, the method further includes subjecting the obtained porous particulate material to processes such as drying, sizing, and sieving in sequence, wherein the drying temperature is lower than the evaporation temperature of the smoke agent. Thus, a porous particulate material with an average particle size of 200 to 600 microns is obtained.

[0103] Further, the extrusion molding can be carried out according to the diameter of the heated cigarette, and corresponding molds can be used to extrude into corresponding shapes; corresponding molds can be used to extrude into corresponding shapes according to requirements such as the shape of the grooves; corresponding molds can be used to extrude into corresponding shapes according to requirements such as the shape of the channels.

[0104] Another embodiment of the present application further provides an aerosol generating system, including any of the above aerosol generating devices and a heating appliance for heating the aerosol generating device.

[0105] In some of these embodiments, the heating appliance includes a heating component, a battery component, a control component, and a housing. The battery component is used to supply power to the heating appliance, the control component is used to control the battery component, and the heating component, the battery component, and the control component are accommodated in the housing.

[0106] Further, the heating component can be a central heating type heating component or a circumferential heating type heating component.

[0107] In order to make the purpose, technical solution, and advantages of the present application more concise and clear, the present application is described by the following specific embodiments, but the present application is by no means limited to these embodiments. The following described embodiments are only the preferred embodiments of the present application and can be used to describe the present application, and should not be construed as a limitation on the scope of the present application. It should be noted that any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application should be included in the protection scope of the present application.

[0108] To better illustrate the present application, the content of the present application will be further described below in conjunction with embodiments. The following are specific embodiments.

[0109] Example 1

[0110] (1) Preparation of the tobacco segment aerosol matrix.

[0111] The aerosol matrix is formed of tobacco sheet. The tobacco segment aerosol matrix adsorbs glycerol, and the content of glycerol is shown in Table 1, with the unit of mg / cigarette, which refers to the mass of glycerol contained in the tobacco segment aerosol matrix in each aerosol device. The same applies hereinafter.

[0112] (2) Preparation of the non-tobacco segment aerosol matrix.

[0113] Adsorb the fuming agent glycerol with the porous material montmorillonite; then granulate the porous material adsorbed with the fuming agent; mix the obtained porous granular material montmorillonite and sodium carboxymethylcellulose aqueous solution, and extrude and form through a mold, wherein the dosage of sodium carboxymethylcellulose is 1 wt% of the porous granular material (the water in the sodium carboxymethylcellulose aqueous solution is removed by heating during extrusion molding), to obtain a cylindrical non-tobacco section aerosol matrix.

[0114] During extrusion molding, grooves are formed on the side wall of the fuming body; specifically, 5 axially penetrating grooves are formed on the side wall, and the cross-sectional shape of the grooves is fan-shaped.

[0115] The non-tobacco section aerosol matrix includes a porous matrix (i.e., a montmorillonite matrix) and the fuming agent glycerol adsorbed in the montmorillonite of the porous matrix. The mass of glycerol contained in the non-tobacco section aerosol matrix is shown in Table 1.

[0116] It can be understood that different porous materials are used, and different porous matrices are formed. If the porous material used is sepiolite, a sepiolite matrix is formed, as shown in Example 3. Other examples are similar.

[0117] (3) Preparation of an aerosol generating device (i.e., a cigarette).

[0118] As Figure 1 shown, the filter element, the hollow device, the non-tobacco section aerosol matrix, and the tobacco section aerosol matrix are sequentially arranged, and the wrapping material layer is used to wrap the outside of the sequentially connected filter element, the hollow device, the non-tobacco section aerosol matrix, and the tobacco section aerosol matrix, to obtain an aerosol generating device.

[0119] Among them, no channels are provided in Example 1. In the non-tobacco section aerosol matrix, the total volume ratio of each groove is the total pore volume ratio abbreviated in Table 1, %.

[0120] Examples 2 to 16

[0121] Examples 2 to 16 are basically the same as Example 1, the difference is that in the preparation of the non-tobacco section aerosol matrix in step (2), at least one of the type of porous material, the glycerol content in the non-tobacco section aerosol matrix, whether to set channels and the shape of the channels is different, as specifically shown in Table 1.

[0122] The channels can be formed synchronously by using a mold during extrusion molding. The shape of the channels and the volume ratio of the channels in the non-tobacco section aerosol matrix are shown in Table 1. In this example, all the provided channels are 1 central hole. Taking Example 2 as an example, a circular channel penetrating through the axis of the non-tobacco section aerosol matrix is set through the extrusion molding process. The total volume ratio of each groove and the channel in Example 2 is the total pore volume ratio abbreviated in Table 1; others are similar.

[0123] Comparative Example 1

[0124] It is basically the same as Example 1, except that a tobacco segment aerosol matrix of the same length is used to replace the non-tobacco segment aerosol matrix in Example 1; at the same time, the total mass of glycerol contained in the tobacco segment aerosol matrix is the same as the total glycerol mass in Example 1.

[0125] Comparative Example 2

[0126] It is basically the same as Example 2, except that a tobacco segment aerosol matrix of the same length is used to replace the non-tobacco segment aerosol matrix in Example 2; at the same time, the total mass of glycerol contained in the tobacco segment aerosol matrix is the same as the total glycerol mass in Example 2.

[0127] The aerosol generating devices (cigarettes) prepared in each example and comparative example were heated by the surrounding heating method, and the heating temperature set value was 220 °C, and the glycerol release amount, glycerol release rate and cigarette appearance were detected. The cigarette appearance was detected by visual observation.

[0128] The process for detecting the glycerol release amount and glycerol release rate is as follows:

[0129] A linear smoking machine was used to suck and heat the heat-not-burn cigarette, and the cigarette sucking parameters were:

[0130] Sucking volume: 55 mL; sucking time: 2 s; sucking interval: 30 s; sucking times: 8; preheating time: 18 s; sucking curve: bell-shaped, and a 44 mm Cambridge filter was used to trap the particulate matter in the aerosol of the heat-not-burn cigarette, and each filter trapped the particulate matter of 5 cigarette samples.

[0131] The GC-TCD method was adopted. For specific references, see "Wang Kang, Liu Jun, Xiao Shaohong, etc. Simultaneous determination of moisture in the aerosol of heat-not-burn cigarettes and the release amounts of nicotine, glycerol, 1,2-propanediol, triacetin and menthol by GC-TCD [J]. Tobacco Science & Technology, 2019, 52(3): 63-68." to test the released glycerol content.

[0132] Glycerol release rate = glycerol release mass / (total mass of glycerol in aerosol matrix + glycerol in independent smoke generator) × 100%.

[0133] Table 1

[0134]

[0135] It can be seen from the detection results in Table 1 that:

[0136] 1. By comparing Comparative Example 1 with Examples 1, 3, 5, etc. where the total glycerol content is the same, and comparing Comparative Example 2 with Examples 2, 4, 6, etc. where the total glycerol content is the same, it can be seen that for the aerosol matrix with a two-stage structure of the non-tobacco section aerosol matrix and the traditional tobacco section aerosol matrix of the present application, when the total glycerol content in the cigarette is the same, the release amount of glycerol increases, and the release rate of glycerol also increases.

[0137] 2. When other conditions remain unchanged, when the total glycerol content in the cigarette increases from 50 mg to 80 mg, the release amount of glycerol also increases; however, the release rate of glycerol decreases.

[0138] 3. By comparing Examples 10 to 12, it can be seen that appropriately increasing the mass ratio of glycerol in the non-tobacco section aerosol matrix to the total glycerol content in the aerosol matrix can increase the release amount and release rate of glycerol.

[0139] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0140] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims, and the specification and the drawings can be used to explain the content of the claims.
