Three-section granular aerosol generating product and aerosol generating system

Abstract

The utility model belongs to the technical field of heating cigarettes, and particularly relates to a three-section particle type aerosol generating product and an aerosol generating system. The aerosol generating product comprises a particle type aerosol generating matrix section, a plugging piece and a filtering section which are sequentially connected in an abutting mode from the far lip end to the near lip end, and a plugging film is arranged at the far lip end of the particle type aerosol generating matrix section. Generally, it is thought that a hollow cooling section needs to be designed in an existing heating cigarette to reduce the smoke temperature, otherwise, the smoke outlet temperature is too high. According to the invention, a hollow cooling section is removed, and a three-section granular aerosol generating product is designed. Compared with a four-section particle type aerosol generating product (a particle type aerosol generating matrix section, a plugging section, a hollow cooling section and a filtering section) with the same length, the three-section particle type aerosol generating product has the unexpected technical effect of reducing the temperature of a cigarette smoke outlet.

Description

Technical Field

[0001] The utility model belongs to the technical field of heated cigarettes, and specifically relates to a three-stage particle aerosol generating product and an aerosol generating system. Background Art

[0002] As consumers pay more attention to health issues and demand more personalized experience in cigarette products, the tobacco industry continues to respond to the upgrading of consumer demand and develop various smoking products with reduced tar and harm. Among them, heated cigarettes are different from traditional cigarette products in that they are heated in a way that satisfies consumers' sensory needs for cigarette products while providing a healthier smoking experience.

[0003] Existing granular heated cigarettes (aerosol generating products) include: a granular aerosol generating matrix section, a sealing member, a hollow cooling section, and a filtering section. The outer wrapping member is usually an integrated outer tube. Since bulk tobacco particles cannot be fixed, they must be filled into the outer tube, and the particles need to be fixed on both sides of the granular aerosol generating matrix section by means of sealing paper and sealing members. In order to gather aerosols, increase the amount of smoke and cool the smoke, the downstream of the sealing member is usually a hollow cooling section, which is generally a cavity defined by the outer tube, and the downstream of the hollow cooling section is the filtering section. However, the presence of the sealing member, the hollow cooling section, and the filtering section increases the cost of cigarette production.

[0004] In order to solve the above problems, this application is proposed. Utility Model Content

[0005] The first aspect of the present application provides a three-stage aerosol generating product, which includes: a particle-type aerosol generating matrix segment, a sealing member and a filter segment that are sequentially abutted from a distal lip end to a proximal lip end, and a sealing film is provided at the distal lip end of the particle-type aerosol generating matrix segment.

[0006] The aerosol generating product does not contain a hollow cooling section.

[0007] Preferably, the particle-type aerosol generating substrate segment contains tobacco particles. Of course, the particle-type aerosol generating substrate segment may also contain other plant particles, such as tea particles, etc. The tobacco particles may be tobacco powder, etc., formed by a granulation process.

[0008] Preferably, the blocking member has an axial airflow channel. The number of the axial airflow channels can be one or more, as long as the particles of the particle-type aerosol generating matrix section can be blocked to prevent them from shifting and an airflow channel is provided so that the aerosol generated by the particle-type aerosol generating matrix section after being heated can be transferred to the filter section.

[0009] The axial air flow channel is arranged at the center of the blocking member, and / or the axial air flow channels are arranged at intervals around the blocking member in the circumferential direction.

[0010] Preferably, the size of the axial airflow channel is smaller than the size of the tobacco particles to prevent the tobacco particles from being stuck in the axial airflow channel.

[0011] Preferably, the filter section is filled with a porous medium, which may be acetate fiber tow, polyethylene terephthalate tow, or the like.

[0012] Preferably, the blocking film is a breathable blocking film or a tearable blocking film, for example, the blocking film is a paper with a certain air permeability, or a material without air permeability but with air holes.

[0013] The tearable sealing film may be a polymer film or a metal foil film so that it can be punctured by a sharp object to provide a smoke passage when in use.

[0014] Preferably, the material of the sealing member is selected from one or more of paper, ceramic, silica gel, polyetheretherketone, cellulose acetate, polylactic acid, polyethylene, polypropylene, polycarbonate, and polyethylene terephthalate.

[0015] The aerosol generating product comprises: an outer tube encapsulating a particle-type aerosol generating matrix section, a blocking member and a filter section. The outer tube can be integrally formed.

[0016] A second aspect of the present application provides an aerosol generating system, the aerosol generating system comprising: an aerosol generating device and the aerosol generating article according to any one of the first aspects;

[0017] Wherein, the aerosol generating device has an aerosol generating product containing chamber;

[0018] The aerosol generating product containing chamber contains at least the particle-type aerosol generating matrix segment of the aerosol generating product;

[0019] The aerosol generating device also has a heating device arranged to perform airflow heating on the particle-type aerosol generating substrate segment.

[0020] The heating device may be a porous metal heating wire, a heating plate, a heating needle, etc., arranged in the air flow channel upstream of the aerosol generating product containing chamber.

[0021] The third aspect of the present application provides use of the three-stage aerosol generating product described in the first aspect for reducing the smoke outlet temperature of heated cigarettes.

[0022] Preferably, the three-stage aerosol generating product described in the first aspect is used to reduce the smoke outlet temperature of heated cigarettes and reduce the CO content of the smoke.

[0023] The fourth aspect of the present application provides a method for reducing the smoke outlet temperature of heated cigarettes, which uses the three-stage particle aerosol generating product described in the first aspect.

[0024] Preferably, the method can also reduce the CO content in flue gas.

[0025] The fifth aspect of the present application provides a method for reducing the outlet temperature of cigarette smoke and the carbon monoxide in the smoke, characterized in that the three-stage particulate aerosol generating product described in the first aspect is used.

[0026] Compared with the prior art, this application has the following beneficial effects:

[0027] 1. It is generally believed that a hollow cooling section must be designed in existing heated cigarettes to reduce the smoke temperature, otherwise the smoke outlet temperature will be too high. This application removes the hollow cooling section and designs a three-stage particle aerosol generating product. Compared with the four-stage particle aerosol generating product of the same length (particle aerosol generating matrix section-sealing section-hollow cooling section-filtration section), the three-stage particle aerosol generating product increases the length of the particle aerosol generating matrix section and also has the unexpected technical effect of reducing the smoke outlet temperature of cigarettes.

[0028] 2. Since the three-stage particle aerosol generating product of the present application has a longer particle aerosol generating matrix segment, the use of a central heating device or a circumferential heating device is likely to cause uneven heating. Therefore, an airflow heating device can be used for heating.

[0029] 3. In the three-stage particle aerosol generating product of the present application, the particle aerosol generating matrix stage is extended, resulting in a longer distance between the blocking piece and the heating element upstream of the aerosol generating product, thereby reducing the risk of high-temperature degradation of the blocking piece due to receiving heat from the heating element.

[0030] 4. In the present application, the blocking member directly contacts the filter section to limit the filter section, thereby solving the problem that the filter section in the four-section particulate aerosol generating product contacts the cavity (hollow cooling section) and cannot be limited and is prone to displacement.

[0031] 5. The three-stage particle aerosol generating product in the present application has a simpler structure and a simpler manufacturing method.

[0032] 6. Compared with the four-stage particle aerosol generating product, if the length of the particle aerosol generating matrix segment is not changed, the three-stage particle aerosol generating product of the present application has a significantly reduced cost because the sealing component is removed and the total length can be shorter.

[0033] 7. Compared with the four-stage particle aerosol generating products of the same length (particle aerosol generating matrix section-blocking component-hollow cooling section-filter section), the three-stage particle aerosol generating products have lower CO content in the flue gas, so they also have the unexpected technical effect of reducing harm. The reason may be that the downstream particle aerosol generating matrix has a certain absorption effect on the CO generated by the upstream particle aerosol generating matrix.

[0045] Figure 1 The three-stage aerosol generating product of Example 1 comprises: an outer tube and a particle-type aerosol generating matrix segment 1, a blocking member 2 and a filter segment 3 which are sequentially abutted from the far lip end to the near lip end in the outer tube, and a blocking film 4 is provided at the far lip end of the particle-type aerosol generating matrix segment 1.

[0047] The preparation method of the three-stage aerosol generating product of Example 1 uses a filling method, in which the outer tube is placed upside down, and the filter section 3, the plugging member 2, and the granular aerosol generating matrix 1 are filled into the outer tube in sequence, and finally the plugging film 4 is glued on the opening of the outer tube for sealing.

[0048] Comparative Example 1

[0049] The aerosol generating product includes: a particle-type aerosol generating matrix section, a plugging member, a hollow cooling section and a filter section which are sequentially connected from the far lip end to the near lip end. The materials of the aerosol generating product are the same as those in Example 1. Only the length of the particle-type aerosol generating matrix section is shortened, and a 16 mm long cavity is reserved between the plugging member and the filter section as the hollow cooling section. The total length of the aerosol generating product and the length of the plugging member and the filter section are the same as those in Example 1.

[0050] Performance Test:

[0051] An aerosol generating system, comprising: an aerosol generating device and an aerosol generating product. The aerosol generating device has an aerosol generating product containing chamber;

[0052] The aerosol generating product containing chamber contains at least the particle-type aerosol generating substrate segment of the aerosol generating product; the aerosol generating device also has a heating device arranged to perform airflow heating on the particle-type aerosol generating substrate segment.

[0053] The specific heating device is a metal wire mesh arranged in the air flow channel of the aerosol generating device, and its position is located upstream of the aerosol generating product storage chamber. When inhaling, the outside air flows into the air flow channel of the aerosol generating device, and the hot air obtained after being heated by the metal wire mesh enters the aerosol generating product storage chamber to heat the particle type aerosol generating matrix segment.

[0054] The aerosol generating products of Example 1 and Comparative Example 1 were tested using the aerosol generating device described above:

[0055] Figure 2 is the outlet smoke temperature curve of the aerosol generating product of Comparative Example 1, Figure 3 This is the outlet smoke temperature curve of the aerosol generating product in Example 1. Figure 2-3 It shows that compared with the four-stage granular aerosol generating product of the same length (granular aerosol generating matrix section-blocking piece-hollow cooling section-filtering section), the three-stage granular aerosol generating product has an unexpected technical effect of reducing the smoke outlet temperature of cigarettes, and the maximum smoke outlet temperature is reduced by about 3 degrees Celsius. Table 1 is the smoke CO measurement results of Comparative Example 1 and Example 1. Table 1 proves that compared with the four-stage granular aerosol generating product of the same length (granular aerosol generating matrix section-blocking piece-hollow cooling section-filtering section), the three-stage granular aerosol generating product has a lower CO content in the smoke, so it also has an unexpected technical effect of reducing harm. It is speculated that the reason may be that the downstream granular aerosol generating matrix has a certain absorption effect on the CO generated by the upstream granular aerosol generating matrix.
