Aerosol-generating article and aerosol-generating system

Abstract

The present application provides an aerosol generating article and an aerosol generating system. The aerosol generating article includes a filter segment, a substrate segment arranged at one side of the filter segment in an axial direction of the aerosol generating article, and an outer wrapper wrapped outside the substrate segment. The aerosol generating device includes a chamber configured to removably receive the substrate segment of the aerosol generating article, and a heater. The aerosol generating system further includes a plug arranged at an end of the substrate segment distal to the filter segment and capable of plugging a gap between the substrate segment and the outer wrapper. The gap between the substrate segment and the outer wrapper is plugged by the plug, which can reduce airflow passing through the gap between the substrate segment and the outer wrapper, thereby reducing the smell of tobacco during smoking. On the other hand, the plug can ensure that the airflow inside the substrate segment increases, thereby allowing the smoke generated by the substrate segment to be well drawn out, increasing the aroma during smoking, and improving the user's smoking experience.

Description

Technical Field

[0001] This application relates to the field of product technology, and in particular to an aerosol generating product and an aerosol generating system. Background Technology

[0002] A heated non-combustible device that releases compounds by heating, rather than burning, an aerosol-forming matrix in an aerosol-generating article. The aerosol-forming matrix can be tobacco or other non-tobacco products, which may or may not contain nicotine.

[0003] In aerosol-generated products used in heated non-combustible devices, the matrix section shrinks inward during heating, resulting in a larger gap between the matrix section and the outer cigarette paper. This causes two problems: firstly, airflow easily passes through the gap between the matrix section and the outer cigarette paper, carrying away impurities and unpleasant odors from the cigarette paper during inhalation; secondly, less airflow passes through the interior of the matrix section, failing to effectively extract the smoke generated during the heating process, thus resulting in a poor overall taste and negatively impacting the user's vaping experience. Summary of the Invention

[0004] This application provides an aerosol generating product and an aerosol generating system to reduce impurities during inhalation, increase aroma during inhalation, and improve the user's inhalation experience.

[0005] This application provides an aerosol generation system, including an aerosol generation device and an aerosol generation article used with the aerosol generation device;

[0006] The aerosol-generating products include:

[0007] Filter tip section;

[0008] The matrix section is arranged on one side of the filter section along the axial direction of the aerosol-generated product;

[0009] An outer wrapping layer, which wraps around the outside of the matrix segment;

[0010] The aerosol generating device includes:

[0011] The chamber is configured to removably receive the matrix segment of the aerosol-generated article;

[0012] A heater is configured to heat the aerosol in the matrix segment to form a matrix to generate aerosol;

[0013] The aerosol generation system also includes a plug, which is disposed at the end of the matrix section away from the filter section and is capable of sealing the gap between the matrix section and the outer coating layer.

[0014] Another aspect of this application provides an aerosol generating article for use with an aerosol generating apparatus, comprising:

[0015] Filter tip section;

[0016] The matrix section is arranged on one side of the filter section along the axial direction of the aerosol-generated product;

[0017] An outer wrapping layer, which wraps around the outside of the matrix segment;

[0018] A plug is disposed at the end of the matrix section away from the filter section and is capable of sealing the gap between the matrix section and the outer wrapping layer.

[0019] The aerosol generating products and aerosol generating systems provided above seal the gap between the matrix section and the outer wrapping layer with a plug. On the one hand, this reduces the airflow passing through the gap between the matrix section and the outer wrapping layer, thereby reducing impurities during suction. On the other hand, it ensures that the airflow inside the matrix section is increased, which can effectively extract the smoke substances generated during the baking of the matrix section, increase the aroma during suction, and improve the user's suction experience.

[0030] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0031] As used herein, the terms 'upstream' and 'downstream' are used to describe the relative positions of elements or portions of elements of an aerosol-generating article in relation to the direction in which the user draws the aerosol-generating article during its use.

[0032] like Figure 1 As shown, an aerosol generation system provided in one embodiment of this application includes an aerosol generation article 100 and an aerosol generation device 200.

[0033] like Figures 2-3 As shown, an aerosol generating apparatus 200 provided in one embodiment of this application includes:

[0034] Chamber 201 is configured to removably receive aerosol-generating article 100;

[0035] Heater 202 is configured to heat aerosol generating article 100 to generate aerosol; the heating method of heater 202 can be resistance heating, infrared heating, electromagnetic induction heating, etc., and is not specifically limited. In the example shown in the figure, heater 202 is configured to heat at least a portion of aerosol generating article 100. In other examples, it is also feasible for heater 202 to be configured to be inserted into aerosol generating article 100 for heating.

[0036] Cell 203 is used for power supply; cell 203 can be a rechargeable cell or a disposable cell.

[0037] Circuit 204 is used to control the aerosol generating device 200; for example, to control the battery cell 203 to provide power to the heater 202.

[0038] In one example, circuit 204 includes a control unit. The control unit is a hardware component configured to control the overall operation of the aerosol generating device 200. The control unit may include at least one processor. The processor may be implemented as an array of logic gates, or it may be implemented as a combination of a general-purpose microcontroller and memory storing a program executable in the microcontroller. Those skilled in the art will understand that the processor can be implemented in other forms of hardware.

[0039] like Figures 4-6 As shown, the aerosol generating article 100 provided in one embodiment of this application has an overall elongated cylindrical structure.

[0040] The appearance of the aerosol generating article 100 can mimic that of a conventional lit and inhalable cigarette. The aerosol generating article 100 can have an outer diameter between approximately 5 mm and 12 mm (e.g., between approximately 6 mm and 8 mm).

[0041] The total length of the aerosol generating article 100 is preferably at least about 35 mm. More preferably, the total length of the aerosol generating article 100 is at least about 40 mm. Even more preferably, the total length of the aerosol generating article 100 is at least about 45 mm. Alternatively, the total length of the aerosol generating article 100 is preferably less than about 80 mm. More preferably, the total length of the aerosol generating article 100 is less than about 75 mm. Even more preferably, the total length of the aerosol generating article 100 is less than about 70 mm.

[0042] In a preferred embodiment, the total length of the aerosol-generating article 100 is about 35 mm to about 80 mm, more preferably about 40 mm to about 75 mm, and even more preferably about 45 mm to about 70 mm.

[0043] The aerosol generating article 100 includes an outer coating layer 101, a filter section 102, a cooling section 103, and a matrix section 104. The filter section 102, the cooling section 103, and the matrix section 104 are arranged sequentially along the axial direction of the aerosol generating article 100; specifically, the filter section 102 is arranged at the downstream end of the aerosol generating article 100; the matrix section 104 is arranged on one side of the filter section 102 along the axial direction, that is, at the upstream end of the aerosol generating article 100; the cooling section 103 is disposed between the filter section 102 and the matrix section 104 along the axial direction.

[0044] The outer wrapping layer 101 is wrapped around the outside of the filter section 102, the cooling section 103, and the matrix section 104. The material of the outer wrapping layer 101 includes, but is not limited to, one or more combinations of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE, and PBAT.

[0045] The filter section 102 is used to filter aerosols, and the user can hold the filter section 102 in their mouth for inhalation. The material of the filter section 102 includes, but is not limited to, one or more combinations of PE (polyethylene), PLA (polylactic acid), PBAT (butylene adipate-co-terephthalate), PP (polypropylene), cellulose acetate, and cellulose acrylic.

[0046] The cooling section 103 is located immediately upstream of and adjacent to the filter section 102. In use, the aerosol-forming matrix is ​​heated, releasing volatile substances that pass along the cooling section 103 toward the downstream end of the aerosol-generating article 100. These volatile substances are cooled within the cooling section 103 to form an aerosol inhaled by the user. In a preferred embodiment, the cooling section 103 includes a cavity extending along its length. This axially extending cavity ensures that the airflow through the cooling section 103 is longitudinally directed without significant radial deviation. The cooling section 103 can cool the aerosol stream drawn through it by means of heat transfer. The components of the aerosol will interact with the space within the cooling section 103 and lose thermal energy.

[0047] In some embodiments, the temperature of the aerosol stream may decrease by more than 10 degrees Celsius as it is drawn through the cooling section 103. In some embodiments, the temperature of the aerosol stream may decrease by more than 25 degrees Celsius or more than 30 degrees Celsius as it is drawn through the cooling section 103.

[0048] The cooling section 103 and the filter section 102 can be made of the same material or different materials.

[0049] The matrix segment 104 is disposed immediately upstream of and adjacent to the cooling segment 103. The matrix segment 104 has an aerosol-forming matrix. The aerosol-forming matrix may include nicotine. A nicotine-containing aerosol-forming matrix may include a nicotine salt matrix. The aerosol-forming matrix may include plant-based material. Preferably, the aerosol-forming matrix includes tobacco-containing material. The aerosol-forming matrix may include homogenized tobacco material, which may be formed by agglomerating particulate tobacco. Alternatively or additionally, the aerosol-forming matrix may include tobacco-free material. The aerosol-forming matrix may include homogenized plant-based material.

[0050] Aerosol forming matrices can include one or more of the following forms: powder, granules, pellets, fragments, filaments, strips, or sheets. Aerosol forming matrices can also contain one or more of the following materials: tobacco leaves, tobacco vein fragments, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco pulp, cast tobacco, and expanded tobacco.

[0051] The aerosol forming matrix may contain at least one aerosol forming agent. An aerosol forming agent is used to describe any suitable known compound or mixture of compounds that promotes aerosol formation in use and is substantially resistant to thermal degradation at the operating temperature of the aerosol-generating article. Suitable aerosol forming agents are known in the art and include, but are not limited to: polyols such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecenoate.

[0052] The aerosol forming matrix may include any suitable amount of aerosol forming agent. For example, the content of the aerosol forming agent, on a dry weight basis, may be equal to or greater than 5% of the aerosol forming matrix, and preferably greater than 30% by weight on a dry weight basis. On a dry weight basis, the aerosol forming agent content may be less than about 95%. Preferably, the content of the aerosol forming agent is as high as about 55%.

[0053] The aerosol forming matrix may also contain tobacco or non-tobacco volatile flavoring compounds that are released upon heating of the aerosol forming matrix. The aerosol forming matrix may also contain one or more encapsulations, which may include, for example, additional tobacco or non-tobacco volatile flavoring compounds, and such encapsulations may melt during heating of the aerosol forming matrix.

[0054] Aerosol-forming matrices can be provided on or embedded in a thermally stable carrier. The term "thermally stable" as used herein refers to a material that is substantially non-degradable at temperatures typically heated to which the aerosol-forming matrix is ​​located (e.g., from about 150°C to about 300°C). The carrier can take the form of powder, granules, pellets, fragments, filaments, strips, or sheets. The aerosol-forming matrix can be deposited on the surface of the carrier in the form of, for example, flakes, foams, glues, or pastes. The aerosol-forming matrix can be deposited on the entire surface of the carrier, or alternatively, it can be patterned to provide non-uniform flavor delivery during use.

[0055] Please refer to this again. Figures 2-3To understand further, the aerosol generation system also includes a plug 205, which is located at the end of the matrix section 104 away from the filter section 102 and can seal the gap between the matrix section 104 and the outer coating layer 101.

[0056] Specifically, the plug 205 is disposed on the aerosol generating device 200 and in the chamber 201. The plug 205 includes a sealing portion 2051 and a venting portion 2052. The sealing portion 2051 is configured as an annular structure and abuts against the end face of the matrix section 104 away from the filter section 102. That is, when the aerosol generating article 100 is received in the chamber 201, the end face of the matrix section 104 away from the filter section 102 abuts against the sealing portion 2051, thereby sealing the gap between the matrix section 104 and the outer coating layer 101. The venting portion 2052 is located radially inside the sealing portion 2051. The venting portion 2052 is a through hole formed by the radially inner sidewall of the sealing portion 2051, allowing external air to flow into the end of the matrix section 104 away from the filter section 102.

[0057] In a further implementation, the aerosol generating device 200 also includes a connector 2053, and the sealing part 2051 is connected to the cavity wall of the chamber 201 through the connector 2053.

[0058] In a further implementation, the connector 2053 is provided with an air passage 2053a so that external air flows into the matrix section 104 away from the filter section 102 through the air passage 2053a and the air vent 2052.

[0059] In this implementation, external air can flow into the chamber 201 through an opening on the aerosol generating device 200, such as an opening for inserting the aerosol generating article 100, and then flow towards the upstream end of the aerosol generating article 100 along the gap between the chamber wall of the chamber 201 and the aerosol generating article 100, and after passing through the air passage 2053a and the air vent 2052, flow into the end of the matrix section 104 away from the filter section 102.

[0060] In the above implementation, external air flows into the end of the matrix section 104 away from the filter section 102, instead of flowing in through the gap between the matrix section 104 and the outer wrapping layer 101. This reduces airflow through the gap between the matrix section and the outer wrapping layer, thus reducing impurities during vaping; it also ensures increased airflow within the matrix section, effectively extracting the smoke generated during the matrix section's baking process, enhancing aroma, and improving the user's vaping experience.

[0061] In a further implementation, the aerosol generating device 200 is also provided with a receiving chamber 206. The opening of the receiving chamber 206 is aligned and connected with the venting part 2052. The receiving chamber 206 can receive the residue that falls off the aerosol generating product 100.

[0062] Figures 7-8 This is a schematic diagram of an aerosol-generating article 100 provided in another embodiment of this application. Figures 1-6 The examples are different, in Figures 7-8 In the example, the plug 205 is not located on the aerosol generating device 200, but on the aerosol generating product 100.

[0063] Specifically, the outer wrapping layer 101 wraps around the outside of the plug 205. The plug 205 includes a sealing portion 2051 and a venting portion 2052. The sealing portion 2051 is configured as an annular structure and abuts against the end face of the matrix section 104 away from the filter section 102, thereby sealing the gap between the matrix section 104 and the outer wrapping layer 101. The venting portion 2052 is located radially inside the sealing portion 2051. The venting portion 2052 is a through hole formed by the radially inner sidewall of the sealing portion 2051, allowing external air to flow into the end of the matrix section 104 away from the filter section 102.

[0064] exist Figures 7-8 In the example, the sealing part 2051 can be made of an airtight material, such as paper sticks, cellulose acetate, non-woven fabric, etc.

[0065] Figure 9 This is a schematic diagram of an aerosol-generating article 100 provided in another embodiment of this application. Figures 7-8 The examples are different, in Figure 9 In the example, the vent 2052 is not a through hole formed by the inner wall of the sealing part 2051. The vent 2052 is located inside the sealing part 2051 and is a solid structure. The vent 2052 is made of a breathable material, so that external air can flow through the vent 2052 into the end of the matrix section 104 away from the filter section 102.

[0066] exist Figure 9 In the example, the breathable part 2052 may be made of a breathable material with pores, including but not limited to one or more of sponge, paper fiber, cotton fiber, polypropylene fiber, polyester fiber, nylon fiber, cellulose acetate, porous ceramic material, and polymer fiber.

[0067] Understandably, in Figure 9 In the example, the vent 2052 may also have Figure 8The through-hole shown can be one or more. In this case, it is also feasible for the vent 2052 to be made of an impermeable material, allowing air to pass through only one or more through-holes. It is also understandable that the embodiment with one or more through-holes on the vent 2052 can replace... Figures 1-6 Examples.

[0068] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
