Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerosol technology, and in particular to an aerosol generating matrix, an aerosol generating device, and an aerosol generating system. Background Technology
[0002] Heated cigarettes are a new type of tobacco product. The heating temperature is only 200℃~400℃, which is significantly lower than the combustion temperature of traditional cigarettes (600℃~900℃). The harmful components produced by the high-temperature combustion of tobacco are greatly reduced. Therefore, it has developed rapidly in recent years.
[0003] There are two main heating methods for heated cigarettes: ambient heating and center heating. Center heating includes resistance heating and electromagnetic induction heating. Resistance heating involves installing a needle-type or plate-type heating needle in the heated cigarette device. During use, the heating needle is inserted into the center of the aerosol-generating matrix section of the heated cigarette, and heating is achieved by controlling the current. Electromagnetic heating involves placing an electromagnetic induction heating element in the center of the aerosol-generating matrix section of the heated cigarette. During use, the current in the induction coil in the heated cigarette device is controlled, generating an alternating magnetic field around the coil. Under the influence of this magnetic field, the electromagnetic induction heating element inside the cigarette generates eddy currents and heats up.
[0004] In traditional technologies, cigarettes and smoking devices adapted to electromagnetic induction heating and resistance heating are not interchangeable, so further improvements are necessary. Utility Model Content

[0044] Traditionally, cigarettes designed for resistance heating devices lack an internal electromagnetic induction heating element, preventing electromagnetic induction heating devices from generating eddy currents and producing heat. Conversely, cigarettes designed for electromagnetic induction heating do have an internal electromagnetic induction heating element, which hinders the insertion of the heating needle in the device. Therefore, electromagnetic induction cigarettes and resistance heating devices are incompatible. This incompatibility between electromagnetic induction heating and resistance heating cigarettes and devices causes numerous inconveniences for consumers and negatively impacts their experience.
[0045] Based on this, this utility model creatively proposes a novel heated cigarette structure.
[0046] Please see Figure 1 The first aspect of this application provides an aerosol generating substrate 100, which includes an aerosol generating matrix 120 and an electromagnetic induction heating device 110. The aerosol generating matrix 120 is wrapped around the outside of the electromagnetic induction heating device 110. The electromagnetic induction heating device 110 has a hollow tubular structure.
[0047] It should be noted that, Figure 1 A is a schematic diagram of the cross-sectional structure of the aerosol generating matrix 100; Figure 1 Figure B is a schematic diagram of the three-dimensional structure of the aerosol generating matrix 100.
[0048] The aerosol generating matrix 120 of this application includes a hollow tubular electromagnetic induction heating device 110. Heated cigarettes containing the aforementioned aerosol generating matrix 100 can be adapted to electromagnetic induction heating devices. Simultaneously, the hollow cavity of the electromagnetic induction heating device 110 can accommodate a plate-type or needle-type heating element, thus making it suitable for resistance heating devices. Furthermore, the tubular electromagnetic heating device increases its contact area with the aerosol generating matrix 120, improving the atomization and release performance of the aerosol generating matrix 120, thereby enhancing the user experience.
[0049] Furthermore, compared with traditional electromagnetic induction heating elements, the hollow tubular electromagnetic induction heating device 110 of this application is completely attached to the aerosol generating matrix 120, which increases the contact area with the aerosol generating matrix 120, thereby improving heating efficiency and atomization effect of the aerosol generating matrix 120; and can achieve better aerosol release effect under relatively low heating temperature conditions.
[0050] When heating a heated cigarette containing the aforementioned aerosol generating matrix 100 using a central heating needle or central heating plate, the electromagnetic induction heating device 110 prevents the heating needle and heating plate from directly contacting the aerosol generating matrix 120, thereby reducing adhesion and improving the service life of the heating device and the consumer's smoking experience.
[0051] In some implementations, the sidewall 111 of the electromagnetic induction heating device 110 has perforations 112. The perforations 112 on the sidewall 111 of the electromagnetic induction heating device 110 can alter the path of aerosol release from the aerosol generating matrix 120. Specifically, as the aerosol evaporates and diffuses from the tobacco sheet to the surrounding area, if the surrounding area is entirely composed of tobacco sheets, a desorption-adsorption equilibrium is easily reached, resulting in a reduced actual evaporation rate. However, when the aerosol diffuses through the perforations into the hollow cavity of the electromagnetic induction heating device, it does not come into contact with the tobacco sheets, thus reducing the adsorption of the evaporated aerosol and increasing the total aerosol release rate, thereby enhancing the consumer experience.
[0052] In some embodiments, the number of perforated holes 112 is at least one, for example, 1 to 100, or it can be within the range of any two integers from 1 to 100.
[0053] In some embodiments, the perforated holes 112 are circular, elliptical, rhomboid, square, or rectangular. In some embodiments, the perforated holes 112 may be regularly arranged on the sidewalls 111 or randomly distributed on the sidewalls 111. Understandably, the perforated holes 112 may also be other polygonal or irregular shapes.
[0054] like Figure 2 As shown, Figure 2 In section A, multiple circular perforated holes 112 are regularly arranged on the side wall 111; Figure 2 In section B, multiple square perforated holes 112 are regularly arranged on the side wall 111; Figure 2 In the middle C, multiple rectangular perforated holes 112 are regularly arranged on the side wall 111; Figure 2 In the middle D, multiple diamond-shaped perforated holes 112 are regularly arranged on the side wall 111; Figure 2 In the middle E, multiple elliptical perforated holes 112 are regularly arranged on the side wall 111.
[0055] In some embodiments, the total area of the perforated holes accounts for 1 / 3 to 2 / 3 of the total area of the sidewall 111 of the electromagnetic induction heating device 110. As an example, the proportion of the total area of the perforated holes can be 1 / 3, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 2 / 3, or any two of the above values.
[0056] Understandably, the total area of the sidewall 111 of the electromagnetic induction heating device 110 refers to the area of the electromagnetic induction heating device 110 without any perforations.
[0057] In some embodiments, the sidewall 111 of the electromagnetic induction heating device 110 is completely in contact with the inner wall of the aerosol generating matrix 120. In this way, the heat generated by the electromagnetic induction heating device 110 can be transferred to the aerosol generating matrix 120 more quickly and heated to cause it to atomize.
[0058] In some embodiments, the cross-sectional shape of the inner cavity of the electromagnetic induction heating device 110 is circular, elliptical, polygonal, or irregular. Further, polygons include, but are not limited to, triangles, quadrilaterals, pentagons, or hexagons. Quadrilaterals include, but are not limited to, squares, rectangles, trapezoids, and parallelograms.
[0059] Understandably, the cross-sectional shape of the inner cavity of the electromagnetic induction heating device 110 refers to the planar shape of the inner cavity obtained by cutting in a direction perpendicular to the axis of the tube.
[0060] In some embodiments, the inner cavity cross-sectional shape of the electromagnetic induction heating device 110 is circular, and the cross-sectional diameter of the electromagnetic induction heating device 110 is 1.5mm~2.5mm.
[0061] In some embodiments, the diameter of the aerosol generating substrate 100 is 5 mm to 9 mm.
[0062] In some embodiments, the inner cavity cross-sectional shape of the electromagnetic induction heating device 110 is elliptical, and the ratio of the major axis length to the minor axis length of the inner cavity cross-section is (2~2.5):1. As an example, the ratio of the major axis length to the minor axis length can be 2:1, 2.1:1, 2.2:1, 2.3:1, 2.4:1, 2.5:1, or within any range of any two of the above values.
[0063] In some embodiments, the length of the major axis is 1.5mm to 3mm, and the length of the minor axis is 0.8mm to 1.5mm. For example, the length of the major axis can be 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, or 3.0mm, or any two of the above values; the length of the minor axis can be 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm, or any two of the above values.
[0064] In some embodiments, the length of the aerosol generating substrate 100 is 10 mm to 35 mm.
[0065] In some embodiments, the ratio of the length of the aerosol generating matrix 120 to the length of the electromagnetic induction heating device 110 is 1:(0.8~1). As an example, the ratio of the length of the aerosol generating matrix 120 to the length of the electromagnetic induction heating device 110 can be 1:0.8, 1:0.81, 1:0.82, 1:0.83, 1:0.84, 1:0.85, 1:0.86, 1:0.87, 1:0.88, 1:0.89, 1:0.9, 1:0.91, 1:0.92, 1:0.93, 1:0.94, 1:0.95, 1:0.96, 1:0.97, 1:0.98, 1:0.99, 1:1, or within the range of any two of the above values.
[0066] Optionally, the ratio of the length of the aerosol generating matrix 120 to the length of the electromagnetic induction heating device 110 is 1:1.
[0067] In some embodiments, the aerosol generating matrix 120 includes one or more of tobacco shreds, tobacco stems, reconstituted tobacco leaves, and tobacco particles.
[0068] Understandably, the aerosol generating matrix 120 may also contain one or more of a smoke generator, a flavoring agent, and other functional additives.
[0069] like Figure 3 As shown, in a second aspect of this application, an aerosol generating device is provided, including a wrapping layer 400, a filter body 300, a hollow device 200 and the aforementioned aerosol generating substrate 100; the wrapping layer 400 wraps around the outside of the filter body 300, the hollow device 200 and the aerosol generating substrate 100 arranged sequentially.
[0070] In some embodiments, the aerosol generating device includes heated cigarettes.
[0071] Because the electromagnetic induction heating device 110 in the aerosol generating matrix 100 has a hollow cavity, airflow can enter the hollow device 200 through the hollow cavity of the electromagnetic induction heating device 110, thereby affecting the distribution uniformity of the aerosol generating matrix 120 and reducing its concentration; thus affecting the consumer experience.
[0072] like Figure 4 As shown, in some embodiments, the aerosol generating device further includes a diffusion device 500 disposed between the hollow device 200 and the aerosol generating substrate 100.
[0073] By placing a diffusion device 500 between the aerosol generating substrate 100 and the hollow device 200, the aerosol generated in the aerosol generating substrate 100 can be diffused more uniformly, thereby improving the customer experience.
[0074] In some embodiments, the length of the diffusion device 500 is 5 mm to 10 mm in the direction in which the aerosol generating matrix 100 extends toward the hollow device 200. As an example, the length of the diffusion device 500 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or within any two of the above values.
[0075] In some embodiments, the cross-section of the diffusion device 500 is the same as the cross-section and shape of the aerosol generating substrate 100, the hollow device 200, and the filter section.
[0076] In some embodiments, the diffusion device 500 has a cylindrical structure. Further, the filter body 300, the hollow device 200, and the aerosol generating substrate 100 also have cylindrical structures, and the encapsulation layer 400 is formed to form a cylindrical structure, which is wrapped around the outside of the cylindrical filter body 300, the hollow device 200, and the aerosol generating substrate 100.
[0077] In some embodiments, the cross-sectional perimeter of the diffusion device 500 is 17mm to 24mm. As an example, the cross-sectional perimeter of the diffusion device 500 can be 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, or 24mm, or within the range of any two of the above values.
[0078] In some embodiments, the diffusion device 500 includes a bundle of cellulose acetate filaments.
[0079] In some embodiments, the cellulose acetate tow has a single denier of 6Y to 10Y, a total denier of 20000D to 30000D, and a pressure drop of 5Pa / mm to 15Pa / mm. Optionally, the cellulose acetate tow has a single denier of 8Y, a total denier of 25000D, a length of 5mm, and a total pressure drop of 60Pa.
[0080] As an example, the denier of the cellulose acetate tow can be 6Y, 7Y, 8Y, 9Y, 10Y, or within the range of any two of the above values.
[0081] As an example, the total denier of the cellulose acetate bundle can be 20000D, 21000D, 22000D, 23000D, 24000D, 25000D, 26000D, 27000D, 28000D, 29000D, 30000D, or within the range of any two of the above values.
[0082] As an example, the pressure drop of the cellulose acetate tow can be 5 Pa / mm, 6 Pa / mm, 7 Pa / mm, 8 Pa / mm, 9 Pa / mm, 10 Pa / mm, 11 Pa / mm, 12 Pa / mm, 13 Pa / mm, 14 Pa / mm, or 15 Pa / mm, or within the range of any two of the above values. Optionally, the pressure drop of the cellulose acetate tow is 12 Pa / mm.
[0083] One end of the diffusion device 500 is in direct contact with the aerosol generating matrix 100. The aerosol generating matrix 120 usually has a relatively high temperature during use. High temperature will reduce the adsorption and retention of aerosols by the diffusion device 500. Therefore, it is sufficient to select a relatively small denier cellulose acetate bundle.
[0084] In some embodiments, the filter element 300 comprises cellulose acetate tow. The cellulose acetate tow in the filter element 300 is typically selected as a high denier single-denier, low total denier tow; for example, a single denier greater than 10Y and a total denier less than 30,000D. This reduces the adsorption and retention of aerosols while maintaining aesthetic appeal. Optionally, the cellulose acetate tow in the filter element 300 has a single denier of 12Y and a total denier of 22,000D.
[0085] like Figure 5 As shown, in some embodiments, the diffusion device 500 includes an outer cladding layer 520 and an inner core layer 510. The pressure drop of the cellulose acetate bundles in the inner core layer 510 is greater than the pressure drop of the cellulose acetate bundles in the outer cladding layer 520, and the end face of the inner core layer 510 completely covers the inner cavity end face of the electromagnetic induction heating device 110.
[0086] Choosing cellulose acetate filaments with a large pressure drop as the inner core layer 510 to completely cover the inner cavity end face of the electromagnetic induction heating device 110 can reduce the airflow diffusing from the hollow cavity of the electromagnetic induction heating device 110 to the hollow device 200, thus not changing the diffusion path of the aerosol generating matrix 120, nor diluting or reducing the concentration and odor richness of the aerosol; while choosing cellulose acetate filaments with a small pressure drop as the outer cladding layer 520, which covers the aerosol generating matrix 120, can effectively diffuse the aerosol generated by the heating of the aerosol generating matrix 120, making its distribution and diffusion more uniform.
[0087] like Figure 6 As shown, in some embodiments, the diffusion device 500 includes a sealing member 530, a connecting member 540, and a housing 550. The sealing member 530 is placed in the inner cavity of the housing 550. The sealing member 530 and the housing 550 are connected by the connecting member 540, forming a cavity between the sealing member 530 and the housing 550. The end face of the sealing member 530 completely covers the inner cavity end face of the electromagnetic induction heating device 110.
[0088] In some embodiments, the number of connecting parts 540 is at least one, for example, 1 to 10, or it can be any two integers from 1 to 10.
[0089] Figure 6 In section A, the sealing component 530 is connected to the housing 550 via two connecting components 540; Figure 6 In section B, the sealing component 530 is connected to the housing 550 via three connecting components 540; Figure 6 In the middle, C is the sealing component 530, which is connected to the housing 550 via four connecting components 540.
[0090] In some embodiments, the diffusion device 500 comprises one or more of resin and metal materials.
[0091] As an example, the resin includes one or more of polyethylene resin (PE), polypropylene resin (PP), and polyethylene terephthalate (PET); it should be noted that this application does not particularly limit the type of resin, and other resins commonly used in the art may also be used.
[0092] As an example, the metal includes one or more of aluminum and its alloys, copper and its alloys, and iron and its alloys; it should be noted that this application does not specifically limit the type of metal, and it may also be other metals commonly used in the art.
[0093] In some embodiments, the cross-sectional shape of the sealing member 530 is the same as that of the electromagnetic induction heating device 110; alternatively, the cross-sectional shape of the sealing member 530 may be slightly larger than that of the electromagnetic induction heating device 110, but smaller than that of the aerosol generating substrate 100. Thus, the sealing member 530 can prevent air from entering the hollow device 200 from the electromagnetic induction heating device 110, reducing the impact of air on the diffusion path of the aerosol generating substrate 120, and preventing a decrease in aerosol concentration due to air ingress, thereby providing a better experience for consumers.
[0094] In some embodiments, the diameter of the housing 550 is the same as the diameter of the aerosol generating substrate 100, the hollow device 200, and the filter section.
[0095] In some embodiments, the sealing member 530 may be cylindrical or disc-shaped.
[0096] Understandably, the tubular housing 550 and the cylindrical sealing member 530 are not in direct contact; they are connected by a connecting member 540. In this way, a cavity for the aerogel to pass through can be formed between the tubular housing 550 and the cylindrical sealing member 530.
[0097] This application does not impose any particular limitation on the position of the connecting member 540, as long as it enables the housing 550 to be connected to the sealing member 530 and remain relatively stable. For example, the connecting member 540 can be connected to the sealing member 530 at the top, bottom, or middle position of the side wall 111.
[0098] In some embodiments, the end where the electromagnetic induction heating device 110 is connected to the hollow device 200 is a closed end.
[0099] Understandably, by setting the end connecting the electromagnetic induction heating device 110 to the hollow device 200 as a closed end, air can be prevented from entering the hollow device 200 from the electromagnetic induction hollow cavity, reducing the influence of air on the diffusion path of the aerosol generating matrix 120, and the aerosol concentration will not be reduced due to the entry of air, thus providing consumers with a good experience.
[0100] Compared with the method of setting up a diffusion device 500, the aerosol device prepared by using an electromagnetic induction heating device 110 with one end closed is simpler and lighter in structure.
[0101] In a third aspect, this application provides an aerosol generating system, including the aforementioned aerosol generating device and heating appliance;
[0102] The heating device is used to heat the aerosol generating substrate 100 or the aerosol generating device.
[0103] In some embodiments, the heating appliance includes a heating component, a battery component, a control component, and a housing. The battery component supplies power to the heating appliance, and the control component controls the magnitude of the current in the battery component. The heating component, the battery component, and the control component are housed within the housing.
[0104] In some embodiments, the heating component may be a center heating component or a circumferential heating component.
[0105] The present invention will be further described below with reference to specific embodiments and comparative examples, but should not be construed as limiting the scope of protection of the present invention. Unless otherwise specified, the raw materials involved in the following specific embodiments are all commercially available, the instruments used are all commercially available, and the processes involved are conventionally chosen by those skilled in the art.

[0113] Performance testing
[0114] a. Electromagnetic induction heating: Current is provided to the induction coil in the cigarette heating device, so that it generates electromagnetic induction with the electromagnetic induction heating device in the aerosol generating matrix 100, thereby achieving heating.
[0115] b. Resistance heating: Insert the heating needle into the hollow position in the middle of the electromagnetic induction heating device 110 in the aerosol generating substrate 100, and control the current to make the heating needle heat up.
[0116] Example 2
[0117] Example 2 is basically the same as Example 1, except that the diffusion device 500 is different; in Example 2, polypropylene resin (PP) is used to prepare the following... Figure 6 The diffusion device 500 shown in Figure A has an airtight sealing component 530 at its center. The diameter of the sealing component 530 is 3 mm. The sealing component 530 is connected to the housing 550 through multiple connecting components 540.
[0118] Example 3
[0119] Example 3 is basically the same as Example 1, except that Example 3 does not include the diffusion device 500, and the end where the electromagnetic induction heating device 110 is connected to the hollow device 200 is a sealed end.

[0122] A heated cigarette is obtained by sequentially connecting a filter body, a hollow device, and an aerosol generating substrate, and then wrapping the filter body, hollow device, and aerosol generating substrate with cigarette paper.
[0123] Performance testing
[0124] A current is supplied to the induction coil in the cigarette heating device, so that it generates electromagnetic induction with the electromagnetic induction heating device in the aerosol matrix, thereby achieving heating.
[0125] Comparative Example 2
[0126] A heated cigarette is obtained by sequentially connecting a filter body, a hollow device, and an aerosol generating substrate, and then wrapping the filter body, hollow device, and aerosol generating substrate with cigarette paper.
[0127] Performance testing
[0128] A heating needle is inserted into the aerosol generating matrix, and the heating needle is heated by controlling the current. The heated cigarette is then evaluated by seven cigarette sensory quality evaluation experts.
