Description

Technical Field

[0001] This invention belongs to the field of aerosol technology, specifically relating to an aerosol generation system and a method for regulating the state of aerosols. Background Technology

[0002] Currently, many technical documents concerning aerosol generation devices and systems have been published, including, for example, heated non-combustible aerosol generation systems. Based on the three elements of combustion, there are three ways to achieve non-combustibility in principle: one is to replace the combustible material; another is to lower the temperature below the ignition point of the combustible material; and the third is to reduce the oxygen content of the combustion accelerant. Patents 202010241328.8 and 202010241686.9 disclose an oxygen-deficient heated cigarette assembly and a sealed heated non-combustible cigarette and assembly. By sealing the smoke-generating section and changing the airflow path, there is no continuous oxygen supply in the smoke-generating section area, thereby achieving the purpose of reducing the oxygen content.

[0003] The aforementioned technical solution prevents external airflow from passing through the smoke-generating section, thus eliminating convective heat transfer, resulting in a more uniform temperature field in the smoke-generating section, reduced energy management difficulty, and more complete release of aroma-producing substances. However, to ensure that airflow does not pass through the smoke-generating section, specific sealing structures are required. For example, sealing elements can be installed on the aerosol generator, which increases the complexity of device manufacturing; or the distal lip of the smoke-generating section can be directly sealed, which increases the complexity of manufacturing aerosol-generated products. Furthermore, the durability of the aforementioned sealing structures is poor.

[0004] Furthermore, in the oxygen-deficient heating process, the lack of airflow over the tobacco makes smoke migration within the smoking section difficult, easily trapping the smoke inside. Although aroma compounds are fully released, the aerosol generation and extraction mechanism of sealed heated non-combustible cigarettes is altered compared to conventional heated cigarette products, resulting in inconsistent diffusion rates of aroma compounds and requiring further improvement in the uniformity and consistency of the smoke.

[0005] To address the above problems, this invention is proposed. Summary of the Invention

[0006] The first aspect of the present invention provides an aerosol generation system, comprising: an aerosol generation device 1 and an aerosol generation article 2;

[0007] The aerosol generating device 1 includes: a tobacco cup 1-1 with side walls and a bottom wall, which has an aerosol generating product receiving cavity inside;

[0008] The aerosol generating article 2 includes a smoke-generating section 2-1 and a functional section 2-2 coaxially arranged from the distal lip end toward the proximal lip end; the functional section 2-2 includes a cavity section 2-2-1 with a cavity, and the sidewall of the cavity section 2-2-1 is provided with a through sidewall through hole 2-2-2; an air passage extending from the outside of the sidewall through hole 2-2-2 to the inside of the sidewall through hole 2-2-2 forms a first airflow channel 4;

[0009] At least a portion of the distal lip of the aerosol generating article 2 is located within the tobacco cup 1-1, and a gap exists between the inner wall of the tobacco cup 1-1 and the outer wall of the aerosol generating article 2.

[0010] When the side wall through hole 2-2-2 is located inside the tobacco cup 1-1, the gap from the side wall through hole 2-2-2 to the bottom of the tobacco cup 1-1 forms a pressure-balanced airflow channel 5;

[0011] When the side wall through hole 2-2-2 is located outside the tobacco cup 1-1, the gap between the inner wall of the tobacco cup 1-1 and the outer wall of the aerosol generating product 2 forms a pressure-balanced airflow channel 5.

[0012] The sidewalls and / or distal lip of the smoke-generating section 2-1 are breathable. The distal lip of the smoke-generating section 2-1 may be open or have breathable paper attached.

[0013] The interface between the pressure-balancing airflow channel 5 and the smoke-generating section 2-1 should be located as far as possible at the distal lip end of the smoke-generating section 2-1. For example, the pressure-balancing airflow channel 5 can be located on the distal lip end face of the smoke-generating section 2-1 or on the distal lip end sidewall of the smoke-generating section 2-1. In this way, if the gas in the pressure-balancing airflow channel 5 flows through the smoke-generating section 2-1, it will flow through the entire smoke-generating section 2-1, having a smaller impact on the temperature field distribution of the smoke-generating section 2-1. If air enters through the sidewall of the smoke-generating section 2-1 that is not at the distal lip end, the temperature upstream of the inlet point will be less affected, while the temperature downstream of the inlet point will be more affected, resulting in a greater overall impact on the temperature field within the smoke-generating section 2-1.

[0014] Preferably, the gap between the side wall through hole 2-2-2 and the opening of the tobacco cup 1-1 forms a common airflow channel 3.

[0015] Preferably, the axial distance between the sidewall through hole 2-2-2 and the near-lip end face of the smoke-generating section 2-1 is less than the axial distance between the sidewall through hole 2-2-2 and the near-lip end face of the cavity section 2-2-1.

[0016] Preferably, the sidewall through holes 2-2-2 are evenly distributed along the circumferential direction of the sidewall of the cavity segment 2-2-1.

[0017] Preferably, the number of sidewall through holes 2-2-2 is not less than one, and all sidewall through holes 2-2-2 are in the same axial position.

[0018] Of course, the axial positions of all the sidewall through holes 2-2-2 can also be different.

[0019] The sidewall through hole 2-2-2 can be at any angle to the sidewall of the cavity segment 2-2-1. In other words, the orientation of the sidewall through hole 2-2-2 can be arbitrary.

[0020] Preferably, the number of sidewall through holes 2-2-2 is 2 to 8, and the hole diameter is 0.2 to 1.0 mm.

[0021] Preferably, the vertical distance between the central axis of the sidewall through hole 2-2-2 and the near-lip end face of the smoke-generating section 2-1 is 0-15mm.

[0022] Preferably, the inner wall of the tobacco cup 1-1 is provided with a clamping part 1-2 to clamp the aerosol generating product 2.

[0023] Preferably, the clamping part 1-2 is at least one fixing rib that protrudes radially relative to the inner wall of the tobacco cup 1-1.

[0024] Preferably, the fixing rib is a strip-shaped protrusion, a spiral-shaped protrusion, or a dot-shaped protrusion.

[0025] The axial length of the fixing rib is unlimited.

[0026] The smoke-generating section 2-1 contains a smoke-generating substance 2-1-1.

[0027] A second aspect of the present invention provides a method for regulating the state of an aerosol, which uses the aerosol generation system described in any one of the first aspects to regulate the state of the aerosol by adjusting the suction resistance of the first airflow channel 4 and the pressure-balanced airflow channel 5.

[0028] Preferably, the method for adjusting the suction resistance of the first airflow channel 4 includes: adjusting the gap size between the inner wall of the tobacco cup 1-1 and the outer wall of the aerosol generating product 2 or adjusting the structural parameters of the side wall through hole 2-2-2;

[0029] The method for adjusting the suction resistance of the pressure balance airflow channel 5 includes: adjusting the gap size between the inner wall of the tobacco cup 1-1 and the outer wall of the aerosol generating product 2, adjusting the gap between the distal lip end of the smoke-generating section 2-1 and the bottom wall of the tobacco cup 1-1, adjusting the air permeability of the distal lip end of the smoke-generating section 2-1, or adjusting the air permeability of the outer wall of the smoke-generating section 2-1.

[0030] Preferably, the method for adjusting the suction resistance of the pressure-balancing airflow channel 5 is to adjust the gap between the distal lip of the smoke-generating section 2-1 and the bottom wall of the tobacco cup 1-1, or to adjust the air permeability of the distal lip of the smoke-generating section 2-1, that is, to place the pressure-balancing airflow channel 5 at the distal lip of the smoke-generating section 2-1. The beneficial effect of this scheme is that the gas flowing through the balancing airflow channel passes through the entire smoke-generating section, and has little impact on the temperature field distribution of the smoke-generating section.

[0031] The specific methods for adjusting the structural parameters of the sidewall through hole 2-2-2 include: adjusting the hole diameter, number of holes, hole position and hole orientation of the sidewall through hole 2-2-2.

[0032] In addition, methods for controlling the state of aerosols also include:

[0033] Adjusting the heating curves of heat sources 1-3 inside the aerosol generating device 1, etc.;

[0034] Adjust the inner diameter of the tobacco cup 1-1, the outer diameter of the aerosol generating product 2, the structure of the clamping part 1-2, and the height, width, and length of the radial protrusion of the fixing rib, etc.

[0035] Adjust the porosity of the smoke-generating material 2-1-1 within the smoke-generating section 2-1, etc.

[0036] Preferably, the smoking substance 2-1-1 includes one or a mixture of several of the following: tobacco shreds, thin sheets, tobacco flakes, tobacco particles, herbal particles, gel, etc.

[0037] Herbal granules are granules made from herbal plants, such as tea granules.

[0038] Of course, the fuming substance 2-1-1 can also be other substances that can generate aerosols.

[0039] In this article, when the aerosol generating device 1 and the aerosol generating product 2 are used, the end closer to the user's lips is referred to as the "proximal lip end", and the end farther away from the user's lips is referred to as the "distal lip end".

[0040] In this article, the direction closer to the central axis of the tobacco cup 1-1 is denoted as "inner", and the direction farther away from the central axis of the tobacco cup 1-1 is denoted as "outer".

[0041] The aerosol of this invention can also be called flue gas.

[0042] The above technical solutions can be freely combined, provided they do not contradict each other.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. The aerosol generation system of the present invention is provided with a first airflow channel 4 and a pressure-balancing airflow channel 5 to introduce air into the aerosol generation product 2. The first airflow channel 4 does not flow through the smoke-generating section 2-1. Its function is to reduce the amount of oxygen supplied to the smoke-generating section 2-1, thereby achieving oxygen-deficient heating of the smoke-generating section 2-1. At the same time, when the user performs a suction action, the outside air enters the cavity section through the first airflow channel 4 and moves towards the lip end, which can also extract and carry the smoke from the smoke-generating section. The pressure-balancing airflow channel 5 flows through the smoke-generating section 2-1. Its function is to balance the pressure changes in the smoke-generating section 2-1 during the suction process. During the suction process, the pressure of the smoke-generating section 2-1 will decrease as the aerosol substances escape. As the suction time increases, the pressure of the smoke-generating section 2-1 will continue to decrease, causing the driving force for the aerosol substances to escape to gradually weaken. The presence of the pressure-balancing airflow channel 5 supplements the pressure in the smoke-generating section 2-1, preventing the smoke from becoming trapped and difficult to diffuse when there is no external airflow passing through it. In simpler terms, without the pressure-balancing airflow channel 5 (i.e., a seal on the distal lip or sidewall of the smoke-generating section 2-1), the smoke generated by the heat in the smoke-generating section 2-1 would only be "pulled" downstream by the aforementioned extraction action. With the pressure-balancing airflow channel 5, external atmospheric pressure directly acts on the distal lip or sidewall of the smoke-generating section 2-1. When the user inhales, in addition to the aforementioned "pulling" action, it also "pushes" the smoke inside the smoke-generating section 2-1 downstream. This forward pull and backward push further facilitates the downstream migration of the smoke.

[0045] In summary, the design of the first airflow channel 4 and the pressure-balanced airflow channel 5 can achieve both oxygen-deficient heating of the smoke-generating section 2-1 and sufficient diffusion and migration of the flue gas in the smoke-generating section 2-1.

[0046] 2. Furthermore, this invention can also regulate the air intake ratio of the two channels by adjusting the suction resistance of the first airflow channel 4 and the pressure balance airflow channel 5. This ratio can be freely adjusted from 100:1 to 1:100, meaning the amount of oxygen entering the smoke-generating section 2-1 can be arbitrarily adjusted. This invention can heat under completely oxygen-free conditions (when the flue gas pressure generated when the smoke-generating section 2-1 is heated is exactly equal to the external atmospheric pressure, the external air can be "pressed down but not allowed to enter" at the interface between the pressure balance airflow channel 5 and the smoke-generating section 2-1, thus achieving complete oxygen isolation of the smoke-generating section 2-1) and under conditions with complete air oxygen content (i.e., when the suction resistance of the first airflow channel 4 is much greater than the suction resistance of the pressure balance airflow channel 5). In summary, the air intake ratio of the two channels in this invention can be arbitrarily adjusted between these two extreme values ​​of 100:1 and 1:100, greatly increasing the flexibility of adjustment. Therefore, this invention can regulate the aerosol formation process, improve the aerosol state, and enhance the sensory quality of the flue gas.

[0047] 3. The aerosol generating device 1 or aerosol generating product 2 of the present invention does not have a sealing structure to isolate the smoke-generating section 2-1 from oxygen, therefore there are no strict requirements for the airtightness of the device, which can improve the durability of the aerosol generating device 1. When manufacturing the aerosol generating product 2, it is not necessary to seal the distal lip of the smoke-generating section 2-1, thus facilitating industrial production.

[0048] 4. The present invention can achieve changes in the sensory quality of flue gas through simple parameter adjustment (such as adjusting the structural parameters of the side wall through hole 2-2-2, etc.), which facilitates diversified product design. Attached Figure Description

[0074] like Figure 11 When the side wall through hole 2-2-2 is not located inside the tobacco cup 1-1, the gap between the inner wall of the tobacco cup 1-1 and the outer wall of the aerosol generating product 2 forms a pressure-balanced airflow channel 5.

[0076] Preferably, the axial distance between the sidewall through hole 2-2-2 and the near-lip end face of the smoke-generating section 2-1 is less than the axial distance between the sidewall through hole 2-2-2 and the near-lip end face of the cavity section 2-2-1. That is, the sidewall through hole 2-2-2 is closer to the smoke-generating section 2-1.

[0077] Preferably, the sidewall through holes 2-2-2 are evenly distributed along the circumferential direction of the sidewall of the cavity segment 2-2-1.

[0087] Preferably, the radial protrusion height of the fixing rib varies with the axial length of the tobacco cup 1-1. For example, the radial protrusion height of the fixing rib gradually decreases from the distal lip end to the proximal lip end, so that the aerosol generating product 2 can be easily inserted into the tobacco cup 1-1.

[0088] Preferably, the fixing rib is disposed near the lip end of the tobacco cup 1-1.

Specifically, functional segment 2-2 consists of a second wrapping member 2-2-4 and a hollow tube wrapped within it. A cavity is formed inside the hollow tube. The through holes in the tube wall of the hollow tube and the through holes in the second wrapping member 2-2-4 communicate to form a side wall through hole 2-2-2. The material of the hollow tube can be arbitrary, such as paper, polymer, etc. The material of the second wrapping member 2-2-4 can be arbitrary, such as paper, polymer, etc., specifically it can be tipping paper. Both the distal and proximal ends of functional segment 2-2 are open.

Figure 11 There is no common airflow channel 3 in the middle.

[0112] A method for regulating the state of an aerosol, which uses the aerosol generation system described above, regulates the state of the aerosol by adjusting the suction resistance of the first airflow channel 4 and the pressure-balanced airflow channel 5.

[0113] Specifically, the method for adjusting the suction resistance of the first airflow channel 4 includes: adjusting the gap size between the inner wall of the tobacco cup 1-1 and the outer wall of the aerosol generating product 2 or adjusting the structural parameters of the side wall through hole 2-2-2;

[0114] The method for adjusting the suction resistance of the pressure balance airflow channel 5 includes: adjusting the gap size between the inner wall of the tobacco cup 1-1 and the outer wall of the aerosol generating product 2, adjusting the gap between the distal lip end of the smoke-generating section 2-1 and the bottom wall of the tobacco cup 1-1, adjusting the air permeability of the outer wall of the smoke-generating section 2-1, or adjusting the porosity of the smoke-generating substance 2-1-1 in the smoke-generating section 2-1.

[0115] The specific methods for adjusting the structural parameters of the sidewall through hole 2-2-2 include: adjusting the hole diameter, number of holes, hole position and hole orientation of the sidewall through hole 2-2-2.

[0116] In addition, methods for controlling the state of aerosols also include:

[0117] Adjusting the heating curves of heat sources 1-3 inside the aerosol generating device 1, etc.;

[0118] Adjust the inner diameter of the tobacco cup 1-1, the outer diameter of the aerosol generating product 2, the structure of the clamping part 1-2, and the height, width, and length of the radial protrusion of the fixing rib, etc.

[0119] When the diameter of the side wall through-hole 2-2-2 is larger than the gap between the distal lip of the smoke-generating section 2-1 and the bottom wall of the tobacco cup 1-1, and when the diameter of the side wall through-hole 2-2-2 is larger than the gap in the outer wall of the smoke-generating section 2-1, the suction resistance of the first airflow channel 4 is less than the suction resistance of the pressure-balanced airflow channel 5. In this case, most of the air entering the tobacco cup 1-1 will flow to the first airflow channel 4, and the remaining small portion of the air will flow to the pressure-balanced airflow channel 5. The advantage of most of the air flowing to the first airflow channel 4 is that it reduces the amount of oxygen supplied to the smoke-generating section 2-1, achieving oxygen-deficient heating of the smoke-generating section 2-1. Therefore, the heating temperature can be increased without worrying about combustion in the smoke-generating section 2-1, resulting in a more complete release of aroma substances. The advantage of a small portion of the air flowing to the pressure-balanced airflow channel 5 is that it provides a small amount of external airflow to the smoke-generating section 2-1, fully increasing the diffusion and migration of the smoke, and increasing the uniformity and consistency of the smoke. The presence of pressure-balanced airflow channel 5 can prevent the phenomenon of smoke "trapping" and difficulty in smoke diffusion caused by the complete absence of external airflow in smoke generation section 2-1.
