By setting the diameter of the inscribed circle of the cavity (51) to be smaller than the diameter of the flavor-enhancing capsule (421), the cavity (51) can block the flavor-enhancing capsule (421), so as to ensure that the flavor-enhancing capsule (421) does not fall out of the cavity (51).

Description

Aromatic blast bead type aerosol generating article and preparation method thereof TECHNICAL FIELD

[0001] The present application relates to the technical field of heat-not-burn cigarettes, in particular to an aromatic blast bead type aerosol generating article and a preparation method thereof. BACKGROUND

[0002] With the increasing emphasis of consumers on health issues and the increasing demand for personalized experiences of cigarette products, the tobacco industry has continuously responded to the demand of consumers and developed various smoking products with reduced tar and harm. Among them, heat-not-burn cigarettes can provide a healthier smoking experience while meeting the sensory needs of consumers due to the different heating methods of cigarettes compared to traditional cigarette products.

[0003] Currently, the common way to add aroma to smoke is to add aroma gel in the support section or add blast beads in the filter section. The problem of aroma addition in the support section is that the aroma decays significantly during the baking process, and the aroma quality consistency before and after is poor. The aroma is thick in the early stage of smoking, but there is almost no aroma effect in the later stage of smoking. Therefore, researchers have also tried to find a method to release the aroma in the support section. The problem of adding aroma blast beads in the acetate fiber filament filter section is that the acetate fiber filament filter section is located at the end. Therefore, when adding blast beads, the blast beads need to be strictly positioned to ensure that they cannot be exposed from the downstream end face of the acetate fiber filament filter section (the end face towards the lip end side). Once there is a little blast bead exposed from the end face of the acetate fiber filament filter section, it will be considered as a defective product. In addition, even if the blast bead is not exposed, it is only close to the end face of the acetate fiber filament filter section, but after being broken by the consumer, there is still a risk of outflow of the aroma substance inside the blast bead. Therefore, the blast bead adding process needs to strictly control the addition position of the blast bead in the acetate fiber filament filter section.

[0004] In addition, the end of the existing aerosol generating article at the lip end is usually a solid acetate tow rod, which currently has the following problems: 1. The high temperature of the smoke may cause the problem of burning the lips. The acetate tow rod as the filter part of the cigarette, due to its proximity to the aerosol generating substrate section (i.e. tobacco section) and its significant filtering effect, it may cause the smoke temperature after passing through the filter to be relatively high. In addition, when the smoke passes through the solid acetate tow rod, the smoke stays in the solid acetate tow rod for a long time, and part of the heat is retained, causing the temperature of the smoke near the lip end to rise, thereby increasing the risk of burning the lips. 2. Consumer's safety concerns about directly contacting the lips with acetate tow. Acetate is a type of synthetic fiber widely used in the production of cigarette filters. Although it is specially treated to meet food safety and hygiene standards, consumers may still have some safety concerns about directly contacting their lips with such materials. Especially when there are small fibers falling off or burrs on the surface of the acetate tow rod, it may increase the irritation or discomfort to the lips.

[0005] On the other hand, the existing aerosol generating article is usually a four-element structure, including an aerosol generating substrate section, a support section, a temperature reduction section, and a filter section, so the corresponding production settings are four-element composite devices, which cannot produce five-element structure aerosol generating articles.

[0006] Therefore, how to ensure good consistency before and after flavoring, reduce the technical difficulty of adding flavoring burst beads to the acetate tow filter section, and avoid the problem of burning the lips with the filter, as well as reduce the consumer's safety concerns about contacting the lips with the filter, is an urgent problem that people hope to solve.

[0007] In order to solve the above problems, the present application is proposed. SUMMARY

[0008] The present application records the direction of movement of the smoke generated by the heating of the aerosol generating substrate 2 as the user smokes the aerosol generating article as from upstream to downstream.

[0009] The aerosol generating article has an upstream and a downstream. Each component in the aerosol generating article, such as the support 3, the composite temperature reduction filter 4, and the end cavity 5, also has an upstream and a downstream.

[0010] The axial direction of the present application is the central axis direction of the aerosol generating article.

[0011] The radial direction of the present application is the direction perpendicular to the axial direction, which is also the cross-sectional direction of the aerosol generating article.

[0012] The first aspect of the present application provides a blast bead flavoring type aerosol generating article, which comprises an outer wrapper 1, and an aerosol generating substrate 2, a support 3, a composite cooling filter 4 and an end cavity member 5 located in the outer wrapper 1;

[0013] The composite cooling filter 4 comprises a hollow cooling member 41 and a filter 42, and the outer side of the hollow cooling member 41 and the filter 42 is wrapped with a shaped paper 43; the outer side of the composite cooling filter 4 and the end cavity member 5 is wrapped with a tipping paper 6;

[0014] The aerosol generating substrate 2 has a wrapping member 21 outside;

[0015] The filter 42 has a flavoring blast bead 421 inside;

[0016] The end cavity member 5 has one or more cavities 51, and the inscribed circle diameter of the cavity 51 is smaller than the diameter of the flavoring blast bead 421, so as to ensure that the flavoring blast bead 421 cannot fall out of the cavity. Here, it is required that the inscribed circle diameter of the cavity 51 is smaller than the diameter of the flavoring blast bead 421, that is, the size of the blast bead that can pass through the cavity is smaller than the diameter of the blast bead added in the filter 42 of the present application.

[0017] Preferably, when the cavity 51 is one, the cavity 51 is located at the central axis, and when the cavity 51 is multiple, the cavities 51 are dispersed in the end cavity member 5;

[0018] When the end cavity member 5 has one cavity located at the central axis, the cross section of the cavity is heart-shaped, star-shaped, polygonal, flower-shaped; when the end cavity member 5 has multiple dispersed cavities, the cross section of the cavity is circular, heart-shaped, star-shaped, polygonal, flower-shaped.

[0019] When the end cavity member 5 has one cavity located at the central axis, the specific shape of the cross section of the cavity is preferably heart-shaped, star-shaped, polygonal, flower-shaped and other special non-circular shapes, and the special shape is used to provide a larger smoke passage and reduce the interception, and at the same time, the flavoring blast bead 421 in the filter 42 upstream of the end cavity member 5 can be blocked. Here, upstream is defined according to the movement direction of the aerosol, and the aerosol moves from upstream to downstream. However, when the end cavity member 5 has multiple dispersed cavities, the size of the cavity is slightly smaller than that of a single cavity, so here the specific shape of the cross section of the cavity is not limited, which can be circular, or heart-shaped, star-shaped, polygonal, flower-shaped and other special non-circular shapes.

[0020] The end cavity member 5 is an acetate tow tube, a paper tube or a non-woven fabric tube;

[0021] The axial length of the end cavity member 5 is one to two times the diameter of the end cavity member 5.

[0022] Preferably, the present application does not limit the position of the flavoring burst in the axial direction of the filter member. Preferably, the burst is in the axial center of the filter member, but it can also be on the side of the filter member close to the hollow cooling member 41, or even on the side of the filter member close to the end cavity segment. Even if it is located in the second half of the filter member, the burst will not fall out of the cavity because the diameter of the inscribed circle of the cavity of the downstream end cavity segment is smaller than the diameter of the flavoring burst 421.

[0023] Preferably, the hollow cooling member 41 has a ventilation hole 411 that penetrates the tipping paper 6, the outer wrapping paper 1, the formed paper 43, and the wall of the hollow cooling member 41. External air enters the hollow interior of the hollow cooling member 41 through the ventilation hole 411 and combines with the smoke.

[0024] Of course, the ventilation hole 411 can also not be provided. In actual operation, whether to provide the ventilation hole 411 can be determined according to the smoking set to which the aerosol generating article is adapted.

[0025] The hollow cooling member 41 is a hollow acetate fiber tow tube, a hollow paper tube, or a hollow non-woven fabric tube, and the wall thickness of the hollow cooling member 41 is 0.2-1.2 mm.

[0026] Preferably, the support member 3 includes a tube wall 31 and a tube cavity 32. The tube wall 31 is a fluted corrugated structure that includes an outer layer 311, an inner layer 312, and a fluted corrugated layer 313 located therebetween. The outer layer 311 defines the outer surface of the support member 3, and the inner layer 312 defines the tube cavity 32.

[0027] The outer layer 311 is selected from paper; the inner layer 312 is selected from tow-like material or sheet material, the tow-like material including acetate fiber tow or polylactic acid tow, and the sheet material including paper, reconstituted tobacco, or sheet material of high molecular material; and the fluted corrugated layer 313 is selected from paper or non-woven fabric having a fluted structure. In actual selection, if a crimped sheet material is needed, non-woven fabric is preferred, and if a smooth sheet material is needed, paper is preferred. In addition, preferably, the fluted corrugated layer sheet material is first pre-pressed to form fluted creases, and then wrapped with the outer layer 211 and the inner layer 212 to form the tube wall of the fluted corrugated structure. Correspondingly, the gathered sheet material rod 221 in the tube cavity is also first pre-pressed to form creases and then gathered, which facilitates the gathering process.

[0028] The cross-sectional shape of the flutes in the fluted corrugated layer 313 is "U" shaped or "V" shaped.

[0029] When the aerosol generating substrate 2 in the present application is a cigarette paper wrapped reconstituted tobacco rod, a reconstituted tobacco sheet, or a tobacco rod that has been integrally formed, the purpose of the support 3 is only to support and provide an airflow passage, so it can be a common pipe with a hollow structure. Of course, the hollow pipe with a groove corrugated structure provided in the present application is only a preferred solution, and any support structure that can achieve the support of the aerosol generating article and allow the passage of smoke in the art is applicable, such as a hollow acetate tow pipe, a hollow paper tube, or a hollow non-woven fabric pipe.

[0030] Preferably, the pipe cavity 32 has a gathered sheet rod 321 inside. The gathered sheet rod 321 is gathered from sheet material, which includes high molecular material, cellulose acetate, paper or non-woven fabric, and high molecular material includes polylactic acid and polycarbonate.

[0031] The structure of the support 3 needs to be determined according to the form of the aerosol generating substrate 2. When the aerosol generating substrate 2 in the present application is a bulk smoking particle, the purpose of the support 3 is not only to support and provide an airflow passage, but also to provide a seal for the smoking particle, so at this time the pipe cavity 32 of the support 3 has a gathered sheet rod 321 inside. Of course, the support structure provided in the present application is only a preferred solution, and any sealing structure that can achieve the sealing of the bulk smoking material and allow the passage of smoke in the art is applicable.

[0032] Preferably, the support 3 has a flavoring component inside.

[0033] Preferably, the flavoring component in the support 3 and the flavoring burst bead 421 in the filter 42 have different aroma flavor characteristics.

[0034] Preferably, flavoring is added to the aerosol generating substrate 2. The flavoring is consistent or inconsistent with the aroma flavor characteristics of the flavoring burst bead 421 in the filter 42. The flavoring burst bead 421 in the filter 42 plays a role of supplementing or converting the aroma of the aerosol generating substrate 2. When the flavoring in the aerosol generating substrate 2 is inconsistent with the aroma flavor characteristics of the flavoring burst bead 421 in the filter 42, at least a double-flavored aerosol generating article can be provided.

[0035] Preferably, the groove corrugated layer 313 or / and the gathered sheet rod 321 has a flavoring substance layer, which serves as the flavoring component. Any commonly used flavoring can be selected, such as natural flavoring materials and tobacco extract. Of course, in order to increase the amount of smoke, the flavoring substance layer can also include a smoking agent, and the smoking agent is selected from propylene glycol and glycerol.

[0036] Whether the support 3 is provided with a flavoring component and the arrangement of the flavoring substance layer depends on the actual situation, that is, the flavoring burst bead 421 can be arranged only in the filter 42, and the support 3 does not have a flavoring function. Of course, when the support 3 is flavored, the flavoring position and method can be flexible, and the flavoring substance layer can be arranged only on the groove corrugated layer 313 or the gathered sheet rod 321, or can be arranged on both the groove corrugated layer 313 and the gathered sheet rod 321. The arranged flavoring substance layer can be a flavoring gel layer, or a flavoring gel layer with porous adsorbent material (such as activated carbon). The porous adsorbent material can adsorb more flavoring substances, increase the flavoring capacity, and further adsorb the flavoring substances into the porous material, which can also slow down the release when heated, thereby achieving the effect of slow release and slow flavoring.

[0037] Preferably, the aerosol generating substrate 2 is in a scattered granular shape, and the wrapping member 21 is a hollow tube;

[0038] Alternatively,

[0039] The aerosol generating substrate 2 is in a sheet shape, a filament shape, or an integrally formed tobacco rod, and the wrapping member 21 is a cigarette paper;

[0040] Alternatively, the aerosol generating substrate 2 is a non-tobacco substrate.

[0041] When the aerosol generating substrate 2 is a non-tobacco substrate, the non-tobacco substrate can be selected from non-tobacco plants or porous inorganic materials, and the shape can be granular, sheet, filament, or an integrally formed structure.

[0042] The non-tobacco substrate can contain flavorings and / or smoking agents.

[0043] For example, the non-tobacco substrate can be a paper-based material containing flavorings and / or smoking agents.

[0044] Preferably, the hollow cooling member 41 is in a tubular structure, and the inner cavity 413 of the hollow cooling member 41 has a diameter of 0.5-2.3 mm;

[0045] The diameter of the flavoring burst bead 421 is 2.8-3.2 mm;

[0046] The end cavity member 5 is in a columnar structure, and the columnar structure has a plurality of axially extending cavities 51 distributed along the outer periphery of the columnar structure. The cavities 51 have a diameter of 1-2 mm;

[0047] The projection area of the inner cavity 413 of the hollow cooling member 41 in the axial direction does not overlap with the projection area of the plurality of cavities 51 in the axial direction. In other words, the inner cavity 413 and the plurality of cavities 51 do not have overlapping areas in the radial direction.

[0048] There is also a problem in the prior art that the filter section of traditional cigarettes generally uses low denier acetate fiber tows. In order to reduce the interception of smoke, the filter section of the existing heat-not-burn cigarettes generally uses high denier and thick diameter tows, which results in a small number of fiber tows. Therefore, when the burst bead is arranged in the filter section of the heat-not-burn cigarette, the burst bead is more likely to slide due to the small number of fiber tows. In addition, due to the limitation of the heating device, the length of the heat-not-burn cigarette is within a certain range. When the length of the filter section is short, for example, 7-8 mm, due to the large number of functional sections of the heat-not-burn cigarette, the burst bead is easy to slide to the upstream section or the downstream section of the filter section when the user pinches the burst bead. This is easy to cause the user to fail to find the burst bead and thus fail to pinch the burst bead to increase the flavor. Or, when the burst bead slides to the downstream section of the filter section, pinching the burst bead again is easy to cause the flavor of the burst bead to be directly sprayed into the user's mouth, affecting the smoking experience.

[0049] In the present application, since the diameter of the inner cavity 413 of the tubular structure of the hollow cooling member 41 is 0.5-2.3 mm, which is much smaller than the diameter of the flavor burst bead 421, even if the flavor burst bead 421 deforms to a certain extent when being pinched, the flavor burst bead 421 is not easy to slide into the hollow cooling member 41. In addition, the center of the columnar structure of the end cavity member 5 has no cavity 51, so the end cavity member 5 also plays a role in blocking the flavor burst bead 421. Even if the flavor burst bead 421 deforms to a certain extent when being pinched, the flavor burst bead 421 will not slide into the end cavity member 5. The above scheme can ensure that the flavor burst bead 421 is limited in the filter member 42 by the hollow cooling member 41 and the end cavity member 5.

[0050] Preferably, the number of the cavities 51 is 3-5. Preferably, the number of the flavor burst beads 421 is one.

[0051] Preferably, the support member 3 is a tubular structure, and the diameter of the inner cavity of the support member 3 is greater than the diameter of the inner cavity 413 of the hollow cooling member 41.

[0052] The above diameter in the present application is the equivalent diameter. The tubular structure is preferably a circular tubular structure.

[0053] The second aspect of the present application provides a preparation method of the burst bead flavored aerosol generating article of the first aspect of the present application. The aerosol generating substrate 2 is in a scattered granular form, or the aerosol generating substrate 2 is in a sheet form, a filament form, or a tobacco rod that has been integrally formed;

[0054] When the aerosol generating substrate 2 is in a scattered granular form, the wrapping member 21 is a hollow tube member, and the preparation method of the aerosol generating article includes the following steps:

[0055] Step one: preparation of a mouth rod strip:

[0056] The hollow cooling piece 41 and the filter piece 42 are compounded by the forming paper 43 first, to obtain the compound cooling filter piece 4;

[0057] Then the wrapping piece 21, the support piece 3, the compound cooling filter piece 4 and the end cavity piece 5 are compounded by the outer wrapping paper 1, to obtain the mouth stick strip;

[0058] Step two, wrapping the tipping paper 6;

[0059] The tipping paper 6 is wrapped outside the compound cooling filter piece 4 and the end cavity piece 5 by the outer wrapping paper 1;

[0060] Step three, filling of the aerosol generating substrate 2:

[0061] The mouth stick strip is in a vertical state, wherein the wrapping piece 21 is vertically upward, and the aerosol generating substrate 2 is filled into the wrapping piece 21 in the form of filling;

[0062] Step four, sealing the distal lip end of the aerosol generating substrate 2:

[0063] The end of the aerosol generating substrate 2 away from the support piece 3 is sealed. The form of sealing can be to set sealing paper at the end. The distal lip end of the aerosol generating substrate 2 refers to the end of the aerosol generating article away from the consumer's lips during smoking, i.e. the end of the aerosol generating substrate 2 away from the support piece 3.

[0064] Preferably, in step one, the mouth stick strip can be cut into multiple mouth sticks, and the multiple mouth sticks are connected by the end cavity piece 5 and / or the wrapping piece 21.

[0065] Preferably, there is a cutting step before step three, which cuts at the connected end cavity piece 5 and / or the connected wrapping piece 21, to cut the mouth stick strip into multiple mouth sticks. More preferably, it is cut at the end cavity piece 5.

[0066] That is, the mouth stick strip in step one can be a single mouth stick, that is, the outer wrapping paper 1 contains a support 3, a composite cooling filter 4, and an end cavity 5 and a wrapping piece 21. Of course, the mouth stick strip in step one can be cut into multiple mouth sticks, that is, the outer wrapping paper 1 contains multiple supports 3, composite cooling filters 4, and end cavity pieces 5 and wrapping pieces 21, and the multiple mouth sticks are connected through the end cavity piece 5 and / or the wrapping piece 21, and the connection has 2 times the axial length of the end cavity piece 5 or the wrapping piece 21. In this case, when step two is performed, it is also necessary to first perform cutting to cut the mouth stick strip into multiple mouth sticks. That is, the axial length of the connected end cavity piece 5 and / or wrapping piece 21 is twice the axial length of the end cavity piece 5 and / or wrapping piece 21 in a single mouth stick. In order to ensure that each mouth stick has a complete end cavity piece 5 and a wrapping piece 21 after cutting.

[0067] When the aerosol generating substrate 2 is in the form of a sheet, a filament, or a tobacco rod that has been integrally formed, the wrapping piece 21 is cigarette paper, and the method for preparing the aerosol generating article includes the following steps:

[0068] S1, first, the hollow cooling piece 41 and the filter piece 42 are combined using the forming paper 43 to obtain the composite cooling filter 4;

[0069] S2, then the aerosol generating substrate 2 is wrapped with the wrapping piece 21;

[0070] S3, then the aerosol generating substrate 2, the support 3, the composite cooling filter 4, and the end cavity piece 5 are combined using the outer wrapping paper 1;

[0071] S4, then the tipping paper 6 is wrapped outside the outer wrapping paper 1 outside the composite cooling filter 4 and the end cavity piece 5 to obtain the aerosol generating article.

[0072] The aerosol generating article of the present application can be combined with multiple sections at a time, and then cut to obtain multiple aerosol generating articles. When combined, the multiple sections of the aerosol generating article are connected through the end cavity piece 5 and / or the aerosol generating substrate 2, and the connection has 2 times the axial length of the end cavity piece 5 and / or the aerosol generating substrate 2. After cutting, each aerosol generating article has a complete end cavity piece 5 and / or aerosol generating substrate 2. More preferably, the cutting is performed at the end cavity piece 5.

[0073] The third aspect of the present application provides a method for flavoring and limiting the position of a burst bead and cooling smoke, which is for an aerosol generating article containing a flavoring burst bead, and the method includes using the aerosol generating article of the first aspect.

[0074] Preferably, the method includes the following steps:

[0075] The aerosol generating substrate 2 is heated, and the smoke generated by the aerosol generating substrate 2 is drawn by the user after passing through the hollow cooling piece 41, the filtering piece 42 and the end cavity piece 5;

[0076] When the smoke moves from the filtering piece 42 to the end cavity piece 5, the smoke enters the cavities 51 distributed along the outer periphery of the columnar structure of the end cavity piece 5, which changes the smoke flow path, prolongs the smoke residence time, disperses the smoke, increases the smoke contact area with the columnar structure, and further cools the smoke.

[0077] According to Bernoulli's principle, during the process of the smoke moving from the filtering piece 42 to the end cavity piece 5, the cross-sectional area of the airflow passage is reduced due to the smaller diameter of the cavities 51 of the end cavity piece 5 than the diameter of the filtering piece 42, which causes the smoke flow rate to increase, the pressure to decrease, and the airflow temperature to decrease.

[0078] At the same time, since the projection of the inner cavity 413 of the hollow cooling piece 41 along the axial direction does not overlap the projection of the cavities 51 along the axial direction, and the cavities 51 are distributed along the outer periphery of the columnar structure, in other words, the center of the columnar structure of the end cavity piece 5 is free of cavities 51. Therefore, the center of the columnar structure of the end cavity piece 5 can block the flavor-enhancing blasting beads 421.

[0079] The acetate fiber tows used in the filtering piece 42 of the present application generally use high single denier and thick tows, so that the number of fiber tows is relatively small, which can reduce the smoke interception effect of the filtering section.

[0080] When the tubular structure of the hollow cooling piece 41 and the end cavity piece 5 is made of acetate fiber tows, high-density acetate fiber tows such as processed low single denier acetate fiber tows are used to avoid the acetate fiber tows in the pipe wall from flowing into the pipe wall, thereby reducing the smoke interception effect of the acetate fiber tows.

[0081] Of course, when the material of the hollow cooling piece 41 and the end cavity piece 5 is silica gel, the smoke can be directly prevented from flowing into the pipe wall, thereby reducing the smoke interception effect of the pipe wall.

[0082] Compared with the prior art, the present application has the following beneficial effects:

[0083] 1. The filter element of this invention contains flavor-enhancing beads. Because a hollow end component is provided downstream of the filter element, the positioning requirements for the flavor-enhancing beads are reduced when applying them. Even if the flavor-enhancing beads are near the downstream end face of the cellulose acetate tow filter section facing the lip end, or even exposed from the downstream end face of the cellulose acetate tow filter section, they will not flow out after being crushed due to the presence of the hollow end component. Furthermore, the flavor-enhancing substances in the hollow end component can still enhance the aroma of the smoke as it passes through. This invention, by providing a hollow end component downstream of the filter element, reduces the technological difficulty of adding flavor-enhancing beads to the filter element.

[0084] 2. The diameter of the inscribed circle of the cavity 51 of the end cavity component 5 of the present invention is smaller than the diameter of the flavor-enhancing bead 421; this is to ensure that the flavor-enhancing bead 421 will not fall out of the cavity 51. Furthermore, when the end cavity component 5 has a cavity located on the central axis, the cross-sectional shape of the cavity is preferably a non-circular special shape such as heart-shaped, star-shaped, polygonal, or flower-shaped. The purpose is to provide a larger flue gas passage and reduce interception while sealing the upstream filter component 42 containing the flavor-enhancing bead 421. This is because for irregularly shaped cavities, as long as the diameter of the inscribed circle of the cavity is smaller than the diameter of the flavor-enhancing bead 421, it is acceptable.

[0085] In addition, the irregularly shaped end cavities can also increase the recognizability and interest of aerosol-generated products.

[0086] 3. This invention incorporates a flavor-enhancing component within the support element and a flavor-enhancing capsule within the filter element. The flavor-enhancing capsule in the filter element replenishes the aroma of the flavor-enhancing component within the support element and facilitates aroma transition during the later stages of inhalation. Specifically, the support element enhances the aroma of the smoke during the initial inhalation phase. When the consumer feels the aroma replenishment is insufficient, they can manually pop the capsule to enhance the aroma in the latter half of the smoke, achieving a supplementary aroma effect. Furthermore, the flavor characteristics of the flavor-enhancing component within the support element and the flavor-enhancing capsule in the filter element can be inconsistent, achieving a change in style characteristics between the early and later stages of inhalation. For example, the flavor-enhancing component within the support element may have a fruity flavor, while the flavor-enhancing capsule in the filter element may have a chocolate flavor. Thus, when the fruity flavor becomes less pronounced, the consumer can manually pop the capsule, transitioning to a chocolate flavor during the latter half of the inhalation.

[0087] 4. The present invention provides an end cavity component downstream of the filter element. The end cavity component extends the distance from the aerosol generation matrix section to the nozzle end, so the temperature of the outer surface of the end cavity component is lower than that of the filter element surface, thereby avoiding the problem of the nozzle end surface of the aerosol generation product being too hot to touch.

[0088] 5. The end cavity component of this invention has an internal airflow channel, which minimizes the interception of flue gas. Therefore, the flue gas stays in the end cavity component for a short time, thus preventing the flue gas from transferring heat to the outer surface and further avoiding the problem of the aerosol-generated product's nozzle surface becoming scalding hot. Simultaneously, because the end cavity component has a small interception of flue gas, placing the end cavity component downstream of the filter component does not significantly increase the suction resistance.

[0089] 6. The end cavity component of the present invention is a hollow cellulose acetate bundle tube, a hollow paper tube, or a hollow non-woven fabric tube. Because it is hollow inside, the material area in contact with the consumer's mouth is reduced, thus reducing the consumer's safety concerns.

[0090] 7. In terms of the preparation method, when the aerosol generating matrix 2 is in the form of scattered granules, the present invention first uses a rolling and laminating method to form the remaining units except for the aerosol generating granule segments. During lamination, cavities for filling the aerosol generating material are reserved. After lamination, the components are cut as needed, and then the cut nozzles with the wrapping element 21 are placed vertically. Next, the aerosol generating material is filled into the wrapping element 21. The present invention uses a method of lamination followed by filling to prepare aerosol generating products. Multiple nozzles can be laminated simultaneously, and then cut and filled with aerosol generating material. Since all units except the aerosol generating material are in the form of lamination, the efficiency is greatly improved compared to filling each unit individually.

[0091] When the aerosol generating matrix 2 is in the form of sheets, filaments, or an integrally formed tobacco stick, the present invention can prepare pentaneous aerosol generating products without changing the original quaternary composite equipment.

[0092] 8. In a preferred embodiment, this application further ensures that the axial projection of the inner cavity 413 of the hollow cooling component 41 does not overlap with the axial projection of the plurality of cavities 51 of the end cavity component 5. Thus, when flue gas moves from the filter component 42 to the end cavity component 5, the flue gas enters the cavities 51 distributed along the outer periphery of the columnar structure of the end cavity component 5.

[0198] Application Example 1

[0199] The aerosol generating articles of Examples 3-4 and Comparative Examples 1-2 are tested for cooling effect and for trapping amount.

[0200] Cooling effect test description: The airflow heating type smoking set test is used, with the smoking program set to 2s for each puff, one puff every 30s, and a puff volume of 35mL, for a total of 7 puffs. The flavor enhancing burst bead 421 is pinched before preheating the aerosol generating article and then puffing. The aerosol generating article delivers smoke to the consumer's mouth. The temperature peak of each puff after the smoke exits the end cavity piece 5 during the puffing process is detected, and the average temperature peak when puffing 7 times is taken as the average smoke temperature.

[0201] Trapping amount test description: The airflow heating type smoking set test is used, with the smoking program set to 2s for each puff, one puff every 30s, and a puff volume of 35mL, for a total of 7 puffs. The entire section of the filter rod, i.e., the support piece 3, the hollow cooling piece 41, the filter piece 42, and the end cavity piece 5, is recorded. The weight difference before and after puffing is the trapping amount.

[0202] The aerosol generating article structures of Examples 3, 4, Comparative Example 1, and Comparative Example 2 can well reduce the temperature of the smoke, and the cooling effect and smoke trapping effect are shown in Table 1. The aerosol generating article has good cooling effect, so that the temperature of the smoke entering the oral cavity after passing through the support piece 3, the hollow cooling piece 41, the filter piece 42, and the end cavity piece 5 in sequence is about 38℃, specifically 37-38℃, the longitudinal channel is always unobstructed, the smoke flows smoothly, the smoke has high flavor saturation, and the user's smoking experience is effectively improved.

[0203] The above examples are the preferred embodiments of the present application, but the embodiments of the present application are not limited by the above examples. Any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present application are equivalent replacement methods and are included in the protection scope of the present application.

[0204] Table 1: Cooling effect and trapping amount data

[0205] Application Example 2

[0206] The high smoke temperature of the aerosol generating article is mainly reflected in the high temperature of the first three puffs of smoke. The reason is as follows: when starting to smoke, the aerosol generating article has accumulated heat due to the preheating of the smoking set, resulting in a higher temperature of the first three puffs of smoke. In addition, the moisture contained in the aerosol generating article vaporizes into water vapor during the first three puffs, resulting in a large amount of high-temperature water vapor in the smoke, which makes the smoke feel hot in the mouth. Therefore, the main purpose of the smoke cooling is to reduce the highest temperature of the first three puffs of smoke.

[0207] This application example uses two identical aerosol generating articles of Example 2 to perform a smoking test to compare the highest value of the temperature of the first three puffs of smoke under the condition of whether the flavor burst is pinched.

[0208] The specific method is as follows: airflow heating type smoking set test is used, and the smoking program is set to 2s for each puff, 1 puff every 30s, and the puff volume is 35mL, a total of 7 puffs. The first aerosol generating article is smoked after preheating without pinching the flavor burst 421. The second aerosol generating article is pinched before preheating and smoking. The temperature of the smoke delivered by the aerosol generating article to the consumer's mouth is tested. The temperature peak of each puff after the smoke exits the end cavity piece 5 during the smoking process is detected, and the highest value of the temperature of the first three puffs of smoke is filled in the table below.

[0209] Table 2

[0210] Application Example 3

[0211] This application example uses two identical aerosol generating articles of Example 3 to perform a smoking test to compare the highest value of the temperature of the first three puffs of smoke under the condition of whether the flavor burst is pinched.

[0212] The specific method is as follows: airflow heating type smoking set test is used, and the smoking program is set to 2s for each puff, 1 puff every 30s, and the puff volume is 35mL, a total of 7 puffs. The first aerosol generating article is smoked after preheating without pinching the flavor burst 421. The second aerosol generating article is pinched before preheating and smoking. The temperature of the smoke delivered by the aerosol generating article to the consumer's mouth is tested. The temperature peak of each puff after the smoke exits the end cavity piece 5 during the smoking process is detected, and the highest value of the temperature of the first three puffs of smoke is filled in the table below.

[0213] Table 3

[0214] As shown in Table 2 and Table 3, after the flavoring burst beads 421 are broken, the highest temperature of the smoke in the first three puffs can be obviously reduced. The reason is that the flavoring substances in the flavoring burst beads 421 absorb heat in the smoke when the flavoring substances are vaporized. Therefore, the flavoring burst beads 421 have the dual effects of flavoring and reducing the temperature of the smoke.
