Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, and in particular to a heated cigarette and an aerosol generating device. Background Technology

[0002] Heated cigarettes are a new type of tobacco product, similar in appearance, structure, and function to traditional cigarettes. Unlike traditional cigarettes, which burn at temperatures above 650°C with an open flame, heated cigarettes primarily produce smoke by heating the tobacco with a heat source. This generates smoke for the consumer to inhale in a non-combustion state (below 400°C), reducing the harmful components produced by the high-temperature combustion of tobacco raw materials. Compared to traditional cigarettes, heated cigarettes are healthier.

[0003] Currently, granular heated cigarettes, as an important category of heated cigarette products, have achieved continuous breakthroughs in technology, products, and markets in recent years due to their relatively simple processing technology, low equipment investment, and superior sensory quality. However, when tobacco granules are used as the smoking material, their large specific surface area (the total area per unit mass of material), approximately three times that of traditional tobacco shreds, results in a large amount of volatile substances being exposed on the granule surface. In the initial heating stage, a large amount of smoke can be released rapidly, but in the later stages, the significant reduction in volatile substances leads to a noticeable decrease in smoke volume, resulting in inconsistent inhalation rates. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of significant smoke attenuation during the inhalation of heated cigarettes, leading to inconsistent inhalation rates. This invention provides a heated cigarette and an aerosol generating device that can avoid smoke attenuation and improve the consistency of inhalation rates.

[0005] This invention provides a heated cigarette, comprising a smoke-generating section, a filter section, and a wrapping layer. The smoke-generating section includes a first smoke-generating material and a second smoke-generating material arranged sequentially along a first direction, which is the direction of smoke flow. The filter section is located downstream of the second smoke-generating material along the first direction. The wrapping layer covers the exterior of the smoke-generating section and the filter section.

[0006] According to another specific embodiment of the present invention, the heated cigarette further includes a cooling section, which is disposed downstream of the second smoke-generating material along the first direction, and the cooling section is located upstream of the filter section along the first direction. The cooling section is made of plant material and is used to reduce the temperature of the smoke.

[0007] According to another specific embodiment of the present invention, the first smoke-generating material is tobacco particles.

[0008] According to another specific embodiment of the present invention, the second smoke-generating material is a tobacco sheet.

[0009] According to another specific embodiment of the present invention, the second smoke-generating material is smoke-generating paper.

[0010] According to another specific embodiment of the present invention, the smoking paper is impregnated with a smoking agent.

[0011] According to another specific embodiment of this utility model, the cooling section is made of tobacco dust.

[0012] According to another specific embodiment of the present invention, a sealing paper is provided at one end of the smoke-generating section away from the cooling section, and the sealing paper is breathable.

[0013] According to another specific embodiment of the present invention, the wrapping layer includes a paper tube extending along a first direction and a trademark paper wrapped around the outside of the paper tube.

[0014] The present invention also provides an aerosol generating device, including any of the aforementioned heated cigarettes. The aerosol generating device further includes a heating needle extending along a first direction. The heating needle can be at least partially inserted into the smoke-generating section. The heating needle is used to heat the first smoke-generating material and the second smoke-generating material.

[0015] Compared with the prior art, this utility model has the following beneficial effects:

[0016] The heated cigarette provided by this utility model includes a smoke-generating section, a filter section, and a wrapping layer. The smoke-generating section comprises a first smoke-generating material and a second smoke-generating material arranged sequentially, with the specific surface area of ​​the second smoke-generating material being smaller than that of the first smoke-generating material. During the smoking process, in the early stage of heating, the tobacco particles of the first smoke-generating material rapidly release smoke, allowing the smoker to quickly obtain smoke and reducing waiting time.

[0021] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Although the description of this utility model will be presented in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this embodiment. On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0022] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0024] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0025] Currently, when tobacco pellets are used as a smoke-generating material, their large specific surface area results in a significant amount of volatile substances being exposed on the pellet surface. Therefore, while pellet-type heated cigarettes can rapidly release a large amount of smoke in the initial heating stage, the smoke significantly decreases in the later stages due to a substantial reduction in volatile substances, leading to inconsistent smoke volume at different inhalation rates.

[0026] To solve the above-mentioned technical problems, this utility model provides a heated cigarette and aerosol generating device, which can avoid smoke attenuation and make the inhalation volume uniform before and after.

[0027] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below.

[0028] refer to Figure 1This utility model provides a heated cigarette, comprising a smoke-generating section 1, a cooling section 2, a filter section 3, and a wrapping layer 4. Specifically, refer to... Figure 1 The smoke-generating section 1 includes sections along the first direction (e.g., Figure 1 A first smoke-generating material 11 and a second smoke-generating material 12 are arranged sequentially (shown in the X direction), with the first direction being the direction of smoke flow. The specific surface area (the total area per unit mass of material) of the second smoke-generating material 12 is smaller than that of the first smoke-generating material 11. For example, the first smoke-generating material 11 is tobacco granules, and the second smoke-generating material 12 is tobacco sheet. A cooling section 2 is located downstream of the second smoke-generating material 12 along the first direction, and is used to reduce the temperature of the smoke. A filter section 3 is located downstream of the cooling section 2 along the first direction. For example, the filter section 3 can be made of cellulose acetate. A wrapping layer 4 is wrapped around the smoke-generating section 1, the cooling section 2, and the filter section 3.

[0029] When a smoker begins to inhale the heated cigarette provided in this embodiment, the smoke-generating section 1 is first heated to produce smoke. Subsequently, the smoke passes through the cooling section 2 and the filtering section 3, and after cooling and filtration, reaches the smoker's mouth. In the early stage of heating, the tobacco particles, which serve as the first smoke-generating material 11, rapidly release a large amount of smoke upon heating, allowing the smoker to quickly obtain smoke and reducing waiting time. In the later stage of heating, the second smoke-generating material 12 replenishes the smoke, preventing smoke attenuation and thus improving the consistency of the inhalation volume.

[0030] Optionally, the second smoke-generating material 12 is smoke-generating paper, which is a highly absorbent paper coated with a smoke-generating agent. Exemplarily, the smoke-generating agent may include glycerin, propylene glycol, aroma components (such as tobacco extract, tobacco essential oil, etc.), and nicotine salts. When the smoke-generating paper is heated, the smoke-generating agent coated on it volatilizes, carrying out aroma substances and nicotine to replenish the smoke, thereby solving the problem of insufficient smoke from tobacco particles in the later stages of heating.

[0031] Optionally, the cooling section 2 is made of plant materials. For example, the cooling section 2 can be made by crushing natural plant raw materials (such as tobacco powder and tobacco dust), mixing them evenly with adhesives, alcohols (such as propylene glycol or glycerol), sugars (such as monosaccharides or polysaccharides), and starch, then extruding and drying them. Typically, a large amount of tobacco powder and tobacco dust are generated during cigarette production. Because the particle size of tobacco powder and tobacco dust is too small to be used in cigarette smoke-generating materials, they are generally treated as waste. This application utilizes these waste materials, not only turning waste into treasure and saving costs, but also adding tobacco aroma to the smoke while cooling it, thus improving the smoking experience.

[0032] Optionally, refer to Figure 1The cooling section 2 has multiple holes 21 extending through it along the first direction. This design facilitates the flow of smoke, reduces the suction resistance for smokers during inhalation, and enhances the inhalation experience.

[0033] Optionally, refer to Figure 1 A sealing paper 5 is provided at one end of the smoke-generating section 1 away from the cooling section 2. The sealing paper 5 has high air permeability. For example, the air permeability (i.e., the volume of air passing through a unit area of ​​material per unit time) of the sealing paper 5 is 10000CU.

[0034] When a smoker inhales a cigarette, air from outside the cigarette can enter the cigarette through the sealing paper 5. Subsequently, the smoke generated in the smoke-generating section 1 flows towards the smoker due to airflow. By using a highly breathable sealing paper 5, this application can reduce the suction resistance during inhalation and improve the smoking experience.

[0035] Optionally, the length of the first smoke-generating material 11 is 8-10 mm, the length of the second smoke-generating material 12 is 5-7 mm, the length of the cooling section 2 is 14-16 mm, and the length of the filtration section 3 is 8-10 mm.

[0036] Optionally, refer to Figure 1 The wrapping layer 4 includes a paper tube 41 extending along a first direction and a trademark paper 42 wrapped around the paper tube 41. The heated cigarettes provided in this application are made by integral filling of a hard paper tube, which makes the cigarettes have a high overall roundness and a uniform and beautiful appearance, avoiding the problem of cigarettes being easily flattened due to poor roundness.

[0037] The present invention also provides an aerosol generating device, see reference. Figure 2 The device includes any of the aforementioned heated cigarettes, and further includes a heating needle 6 extending along a first direction. The heating needle 6 is at least partially inserted into the smoke-generating section 1, and is used to heat the first smoke-generating material 11 and the second smoke-generating material 12. When a smoker begins to smoke the cigarette, the heating needle 6 is first inserted into the smoke-generating section 1, and the heating needle 6 is used to heat the first smoke-generating material 11 and the second smoke-generating material 12 within the smoke-generating section 1 to generate smoke.

[0038] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
