Description

Technical Field

[0001] This invention belongs to the field of heated cigarettes, specifically relating to an aerosol generating product and cigarette with cooling and sealing functions. Background Technology

[0002] With the improvement of living standards, people are paying more and more attention to their health, and the health risks of smoking have received considerable attention in recent years. To meet changing consumer demands, major domestic and international companies have developed various heated tobacco products (HTPs) to replace traditional cigarettes. HTPs heat the tobacco's smoking section to produce smoke, resulting in a more palatable flavor. Currently, commercially available HTPs mainly consist of a smoking section, a hollow support section, a cooling section, and a filter. The tobacco in the smoking section can be in the form of: ordered or disordered reconstituted tobacco flakes, shredded tobacco, granular tobacco, or blocky tobacco. When the tobacco in the smoking section is heated, the flavorings and smoke-generating agents loaded on it evaporate, producing smoke.

[0003] When the smoke-generating section contains tobacco particles, it is typically filled with tobacco particles in the cigarette stick or cartridge. The distal end of the smoke-generating section is sealed with a sealing film, and the proximal end is sealed with a perforated plug. The perforated plug is used to seal the smoke-generating particles to prevent leakage while allowing smoke to flow.

[0004] In granular heated cigarettes, the average diameter of the smoke particles is typically controlled between 1.5 and 0.8 mm. For the sealing component to function effectively, the vents at its front end must be smaller than 0.8 mm, usually around 0.3 to 0.6 mm. Therefore, manufacturing an array of these small holes at the front end of the sealing component increases the design and manufacturing complexity and cost. While prefabrication can improve efficiency and reduce costs, it may not be the optimal solution. Furthermore, even with an array of vents, some of the smoke from the cigarette may still be blocked by smaller particles, affecting the overall smoke output and the user's smoking experience.

[0005] In addition, to change or increase the amount of smoke in a cigarette, it is generally achieved by drilling holes in the hollow support section or cooling section of the cigarette. However, adding multiple small holes to the diameter of a small cigarette will increase the manufacturing difficulty and cost, and also make it more difficult to adjust the air permeability of the cigarette.

[0006] To address the above problems, this invention is proposed. Summary of the Invention

[0027] Preferably, the petal core 4 is located upstream of the cup-shaped front plug 2, and the petal core 4 includes a plurality of intersecting ribs 42, with the end cap 41 located at the end of each rib 42.

[0028] Preferably, a positioning core 43 is provided at the intersection of several intersecting ribs 42 of the petal core 4, and a front positioning hole is provided at the center of the bottom of the cup-shaped front plug 2. The positioning core 43 is interference-fitted with the front positioning hole to realize the detachable connection between the petal core 4 and the cup-shaped front plug 2.

[0029] Preferably, a transverse partition is provided inside the hollow cavity 6 of the near-lip end sealing device II, and the transverse partition has through holes;

[0032] Preferably, the thickness of the open elastic valve 02 is uniform or gradually increases from the central heating element insertion port 01 to the edge. When the thickness of the open elastic valve 02 gradually increases, it is a continuous increase, that is, both sides of the valve are smooth arc-shaped.

[0033] Preferably, the thickness of the open elastic valve 02 is 1 / 20 to 1 / 2 of the thickness of the distal lip occluder.

[0038] The connection between the distal lip end face 03 of the tube body 0 and the side wall is a chamfer or rounded transition of 10 to 60 degrees.

[0039] Preferably, the near-lip end sealing device II is filled with fragrance-storing cotton.

[0040] A second aspect of the present invention provides a cigarette comprising an aerosol generating article as described in any one of the first aspects and a cigarette tube inserted into the aerosol generating article.

[0041] The flue may contain a cooling section and a filtration section IV.

[0042] Preferably, the shape of the aerosol generating substance is selected from one or more of the following: granular, rod-shaped, block-shaped, and filamentous.

[0043] The aerosol generating material can be selected from plant raw materials such as tobacco and tea.

[0044] Another way to describe the aerosol-generating substance of the present invention is as a smoke-generating substance. Another way to describe the aerosol-generating article is as a cigarette or a cigarette portion having a smoke-generating section.

[0045] In this invention, "proximal lip end" and "distal lip end" are relative terms. When the aerosol-generated product is heated and aspirated, the end closer to the user's lips is the "proximal lip end," and the end farther from the user's lips is the "distal lip end." The distance from the "distal lip end" to the "proximal lip end" is denoted as from upstream to downstream.

[0046] The above technical solutions can be freely combined without contradiction.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] 1. The distal lip sealing component of the aerosol generating product of the present invention is provided with an open elastic valve 02. The open elastic valve 02 has at least one flap, and a heating element insertion port 01 is provided at the center of the open elastic valve 02. The thickness of the open elastic valve 02 is 1 / 20 to 1 / 2 of the thickness of the distal lip sealing component. The purpose is to allow the open elastic valve 02 to utilize its own elasticity to ensure self-adaptation to existing sheet-like, cross-shaped, or needle-type heating elements, facilitating flexible insertion of the heating element. When no heating element is inserted, the open elastic valve 02 can seal the stored particulate smoke-generating material while allowing air to pass through. When the heating element is inserted, the open elastic valve 02 can effectively receive the heating element into the tube 0 for normal heating.

[0049] Furthermore, the near-lip sealing device of the aerosol-generated product of the present invention has a hollow cavity 6, with smoke flowing through an inlet 21 and an outlet 11 at both ends. The smoke entering the near-lip sealing device II at high speed through the inlet 21 drives the initially relatively still surrounding gas to generate various complex micro-circulations such as eddies and turbulence. This allows the airflow in the near-lip sealing device II to undergo more thorough heat exchange, achieving a new balance of heat, pressure, and flow rate. The smoke is then output from the outlet 11, thereby reducing heat within a certain range and balancing pressure and flow rate. In addition, the near-lip sealing device II has a relatively large inner surface area, which can absorb some of the heat radiation from the flowing high-smoke smoke to a certain extent, thus playing a certain cooling role. This further reduces the structural requirements of the hollow cooling section III that matches the cigarette stick or cartridge; for example, the length of the hollow cooling section III can be shortened.

[0050] 2. In the preferred technical solution, the near-lip end sealing device II is further provided with a front air guide pipe 23 and / or a rear air guide pipe 13, which prolongs the path length of the flue gas flowing through the near-lip end sealing device II, increases the residence time of the flue gas in the near-lip end sealing device II, and plays a role in absorbing heat and cooling the flue gas and homogenizing the airflow pressure, thereby increasing the user's comfort when smoking the flue gas.

[0051] 3. In the preferred technical solution, the near-lip end sealing device II can be conveniently filled with fragrance cotton. The fragrance cotton not only enhances the aroma of the smoke, but the fragrance substances in the fragrance cotton also absorb the heat of the smoke and volatilize, thus cooling the smoke and increasing the user's comfort when smoking.

[0052] 4. In the preferred technical solution, the side wall of the near-lip end sealing device (II) is provided with a vent hole 51, and the outer wall of the cigarette cartridge or cigarette stick is also provided with a vent hole communicating with the vent hole 51, so that outside air can enter the near-lip end sealing device II to cool the smoke in the hollow cavity 6 of the near-lip end sealing device II.

[0053] 5. In the preferred embodiment, each flap of the open elastic valve 02 transitions smoothly from thin to thick from the center near the insertion hole of the heating element to the edge. This further enhances the self-adaptability of the flaps to the inserted heating element, and also provides excellent containment and sealing functions for the internally stored particulate smoke-generating material. Simultaneously, the edges of the open elastic valve 02 are thicker, making it less prone to tearing and easier to shape and fill.

[0054] 6. The aerosol-generating product of the present invention combines the storage and isolation / blocking functions of existing particulate products for particulate smoke-generating materials. It can be directly used by mounting it on a paper tube or corresponding device with cooling and filtering functions, and it changes the structure of existing particulate smoke products. Of course, the aerosol-generating product of the present invention can also be used as a cartridge in smoking devices with a mouthpiece.

[0055] 7. This type of individually molded aerosol generating product, which can be heated and atomized to form an aerosol, can contain smoke particles of different flavors. Together with empty smoke tubes of different colors and / or sticker designs, and with a specially designed heating device, it allows consumers to have a variety of flexible and varied ways of using it. This changes the fixed usage of existing granular products and may win the favor of more consumers.

[0056] 8. Simultaneously, the empty cigarette tube can be reused. Each time it is used, only the aerosol generating component needs to be disassembled and replaced. Therefore, this invention transfers the disadvantages of the long production process and processing cycle of existing granular heated tobacco products made from a single complete paper tube to a hands-on experience that consumers can enjoy. This not only motivates consumers to play with and smoke, providing a brand-new consumer experience, but also appropriately shortens the processing cycle of a single cigarette for producers, achieving a win-win situation for both producers and consumers. Of course, it can also produce a new structure of granular cigarettes that can be used with a fixed cigarette tube, enriching the product series of granular heated atomizing products.

[0072] Example 1

[0073] like Figure 1 An aerosol generating article, the aerosol generating article comprising: a tube body 0;

[0074] The tube body 0 contains particulate aerosol generating substances;

[0075] The near-lip end of the tube body 0 is connected to a near-lip end sealing device II, and the far-lip end of the tube body 0 is provided with a far-lip end sealing component;

[0076] In this embodiment, the near-lip sealing device II is designed as follows:

[0077] The proximal lip sealing device II includes: a cup-shaped front plug 2 and a cup-shaped rear plug 1;

[0078] The cup-shaped front plug 2 has two input holes 21 at its bottom;

[0079] The cup-shaped rear plug 1 has an output hole 11 at the center of the bottom of the cup;

[0080] The cup-shaped front plug 2 and the cup-shaped rear plug 1 are opposite each other and detachably connected, forming a hollow cavity 6 inside the near-lip end sealing device.

[0081] Both the tube body 0 and the near-lip end sealing device II are made of high-temperature resistant silicone and are integrally molded using injection molding.

[0082] The cup-shaped front plug 2 and the cup-shaped rear plug 1 are detachably connected via the sidewalls of their respective cup-shaped structures. Specifically, the sidewall end of the cup-shaped structure of the cup-shaped front plug 2 has an axially extending front cylindrical extension 22. The front cylindrical extension 22 forms an annular recess A inside the cup-shaped front plug 2. The sidewall end of the cup-shaped structure of the cup-shaped rear plug 1 has an axially extending rear cylindrical extension 12, and the rear cylindrical extension 12 forms an annular recess B outside the cup-shaped rear plug 1.

[0083] The front cylindrical extension 22 and the rear cylindrical extension 12 are transitionally or interference-fitted to achieve the connection between the cup-shaped front plug 2 and the cup-shaped rear plug 1. Figure 2 The near-lip end sealing device II is used in the process. The overall length L of the near-lip end sealing device II is greater than its maximum outer diameter D (i.e., the length-to-diameter ratio L / D>1) in order to prevent the near-lip end sealing device II from tipping over or getting stuck when it is installed in the flue pipe, which would affect production efficiency.

[0084] The cup-shaped pre-plug 2 is equipped with a pre-ventilation tube 23 integrated therewith, and the pre-ventilation tube 23 is coaxially arranged with the outer wall of the cup-shaped pre-plug 2. The pre-ventilation tube 23 is a hollow column. The axial length of the pre-ventilation tube 23 is less than the length of the hollow cavity 6 of the near-lip end sealing device II, so as to reserve space for gas outflow.

[0085] A rear air guide tube 13, integrated with the cup-shaped rear plug 1, is also added inside it. The rear air guide tube 13 is also coaxially arranged with the outer wall of the cup-shaped rear plug 1. The axial length of the rear air guide tube 13 is less than the axial length of the hollow cavity 6 of the near-lip end sealing device II, so as to reserve space for gas outflow.

[0086] The outer diameter of the rear air tube 13 is smaller than the inner diameter of the front air tube 23, so a portion of the rear air tube 13 is located inside the front air tube 23, and there is a sufficient gap for ventilation between the two.

[0087] Figure 1 As can be seen from b, in this embodiment, the distal lip sealing element is designed as follows:

[0088] The distal lip of the tube body 0 is a single-piece cast end face 03. End face 03 serves as the distal lip sealing element. A "+" shaped slit is provided in the central part of end face 03. The "+" shaped slit serves as a through hole. A thinner silicone open elastic valve 02 is provided around the "+" shaped slit at the distal lip of end face 03. The open elastic valve 02 is also integrally cast with end face 03.

[0089] The open elastic valve 02 is an extension of the transition area between the end face 03 and the "+" shaped gap. It differs in thickness from the end face 03 and is connected to it by an arc. This design allows it to adapt to heating elements of different shapes and effectively prevents the granular smoke-generating material stored inside the tube body 0 from leaking out. The end face 03 has a recess that matches the shape of the open elastic valve 02 to accommodate it, ensuring that the open elastic valve 02 and the rest of the end face 03 are essentially on the same plane.

[0090] The open elastic valve 02 has four flaps, which are arranged in a cross shape. A cross-shaped heating element insertion port 01 is provided at the center of the four flaps. The through hole in the central part of the end face 03 is opposite to and through the heating element insertion port 01 to realize the insertion of the heating element.

[0091] The thickness of end face 03 is m, which is 0.4–1.5 mm. In the open elastic valve 02, the thickness n of the valve, at the edge of the thinnest valve center, is preferably 0.1–0.3 mm, and at most not exceeding 0.5 mm. The width p of the "+" shaped heating element insertion port 01 is recommended to be 0.01–0.2 mm. The width q of each valve is recommended to be 1.5–5 mm. The thickness of the open elastic valve 02 is either uniform or gradually increases from the center to the edge of the "+" shaped heating element insertion port 01.

[0092] The purpose of setting up the open elastic valve 02 is to allow the open elastic valve 02 to utilize the elasticity of the silicone itself to ensure self-adaptation to existing sheet-like, cross-shaped, or needle-shaped heating elements, facilitating flexible insertion of the heating element. When no heating element is inserted, the open elastic valve 02 can seal the internal granular material while allowing air to pass through. When the heating element is inserted, the open elastic valve 02 can effectively receive the heating element into the tube 0 for normal heating.

[0093] Of course, the type of heating element can be flexibly selected based on the diameter of the cigarette and the type of heating element used to heat the particle storage device of this invention. When it is necessary to insert a heating element of other geometric shapes, the heating element insertion port 01 and the open elastic valve 02 in the middle can also be modified accordingly, which is also protected by this invention.

[0094] Both ends of the tube body 0 are provided with chamfered or rounded transitions for easy insertion (or setup) to ensure better delivery or installation. The inner wall of the tube body 0 is provided with an inner flange 04 to limit the near-lip end sealing device. After the near-lip end sealing device is inserted into the tube body 0, the cup-shaped front plug 2 abuts against the inner flange 04. The cup-shaped rear plug 1 of the sealing component II is exposed relative to the tube body 0.

[0095] Figure 2 A type of cigarette that contains the above-mentioned... Figure 1 The aerosol generating article and the smoke tube inserted into the aerosol generating article. The aerosol generating article has an insertion part for inserting into the smoke tube. Specifically, Figure 1 The cup-shaped rear plug 1 is exposed relative to the tube body 0, thus forming a concave platform that serves as a connector.

[0096] The flue includes: a cooling section III that contacts the aerosol-generating product, and a filtration section IV downstream of the cooling section.

[0097] Example 2

[0098] like Figure 3 An aerosol generating product, differing from Example 1 in that the front air guide tube 23 and the rear air guide tube 13 are replaced with a coaxial core 3 disposed within the hollow cavity 6 of the sealing member. The upper end of the sidewall of the cup-shaped front plug 2 has an extending front cylindrical extension. The front cylindrical extension forms an annular recess A inside the cup-shaped front plug 2. The lower end of the sidewall of the cup-shaped rear plug 1 has an extending rear cylindrical extension, which forms an annular recess C inside the cup-shaped rear plug 1. The coaxial core 3 is interference-fitted with the cup-shaped rear plug 1 and the cup-shaped front plug 2 at the central annular recess A and annular recess C.

[0099] The coaxial core 3 is composed of a hollow inner cylinder 32 and a hollow outer cylinder 34 arranged coaxially. The upper end face of the coaxial core 3 is open, and the lower end face has two or more external through holes 31. The two external through holes 31 are radially positioned between the side walls of the hollow inner cylinder 32 and the side walls of the hollow outer cylinder 34. The coaxial core 3 is located in the middle of the hollow cavity 6 of the near-lip sealing device II, so that the external through holes 31 communicate with the annular space 35 between the side walls of the hollow inner cylinder 32 and the side walls of the hollow outer cylinder 34 and the interior of the cup-shaped front plug 2. The side wall of the hollow inner cylinder 32 is provided with two internal through holes 33 to connect the annular space 35 with the interior space of the hollow inner cylinder 32. The interior of the hollow inner cylinder 32 communicates with the output hole 11.

[0100] Specifically, the annular space 35 between the sidewall of the hollow inner cylinder 32 and the sidewall of the hollow outer cylinder 34 is connected to the input hole 21 only through the external through hole 31.

[0101] When the aforementioned near-lip sealing device II is in operation, smoke enters through the inlet 21 of the cup-shaped front plug 2. Under the smoker's suction pressure, the smoke enters the annular space 35 between the sidewalls of the hollow inner cylinder 32 and the hollow outer cylinder 34 through the outer throughlet 31. Then, the smoke enters the space inside the hollow inner cylinder 32 through the inner throughlet 33 and is output from the outlet 11 to the next cavity of the cigarette or cartridge. During this process, the smoke undergoes multiple axial and radial movements within the entire baffle sealing device II, achieving baffle motion. This process prolongs the residence time of the smoke within the entire near-lip sealing device II, thus cooling the smoke.

[0102] Furthermore, during the aforementioned process, as the flue gas flows within the near-lip sealing device II, it passes through multiple small holes and multiple spaces with varying volumes. These volume changes cause pressure changes, resulting in a pressure differential. Under the influence of this pressure differential, multi-regional microflows are generated within the near-lip sealing device II, homogenizing heat and pressure differences. Additionally, this design increases the degree of flue gas mixing, homogenizes flue gas temperature and smoke concentration, and enhances the user's comfort when inhaling the flue gas.

[0103] Figure 4 It is a type of granular cigarette, which contains the above-mentioned... Figure 3 The aerosol generating article and the smoke tube inserted into the aerosol generating article. The aerosol generating article has an insertion part for inserting into the smoke tube. Specifically, Figure 3 The cup-shaped rear plug 1 is exposed relative to the tube body 0, thus forming a recessed platform that serves as a connector. The flue includes: a cooling section III that abuts against the aerosol generating product, and a filtration section IV downstream of the cooling section.

[0104] Example 3

[0105] like Figure 5 An aerosol generating product, differing from Example 1 in that the proximal lip sealing device II has a symmetrical structure. The cup-shaped front plug 2 has eight circumferentially distributed inlet holes 21. The cup-shaped rear plug 1 has eight circumferentially distributed outlet holes 11. The upper end of the sidewall of the cup-shaped structure of the cup-shaped front plug 2 has an extending front cylindrical extension. The front cylindrical extension forms an annular recess A inside the cup-shaped front plug 2. The lower end of the sidewall of the cup-shaped structure of the cup-shaped rear plug 1 has an extending rear cylindrical extension, which forms an annular recess C inside the cup-shaped rear plug 1.

[0106] And a petal core 4 is provided upstream of the cup-shaped front plugging member 2 and downstream of the cup-shaped rear plugging member 1 respectively. In this way, during assembly, it is not necessary to consider which side of the plugging member II should "prioritize" facing the smoke particles, which is more convenient for automated production using equipment, can also reduce the investment in process equipment such as molds in the initial stage of device R & D, and is more conducive to automated production. It is a more optimized, feasible and innovative technical solution.

[0107] The specific structure of the petal core 4 is as follows:

[0108] As Figure 5 As shown in FIGS. 5a and 5c, a positioning core 43 is provided at the center of the petal core 4. A front positioning hole 22 is provided at the center of the bottom of the cup-shaped front plugging member 2. The front positioning hole 22 coincides with the outer contour of the positioning core 43, and the two are in interference fit.

[0109] The petal core 4 further includes four "rice" - shaped cross - arranged rib plates 42. The positioning core 43 is fixedly connected at the intersection of the rib plates 42. Two cylindrical end caps 41 are respectively connected to the end of each rib plate 42. A "rice" - shaped groove that cooperates with the rib plates 42 is provided at the front end of the cup-shaped front plugging member 2. Figure 5 Not shown in the figure. The four "rice" - shaped cross - arranged rib plates 42 are arranged in the "rice" - shaped groove to ensure that after the petal core 4 is axially positioned with the positioning core 43 at the center, the correct circumferential position of each cylindrical end cap 41 in the middle of the input hole 21 or output hole 11 is ensured to obtain a balance, so that: an annular gap with a distance less than the average particle size of the particulate smoke - generating material is formed between the outer wall of the end cap 41 and the inner wall of the input hole 21 or output hole 11. This annular gap serves as an air flow channel.

[0110] Similarly, in Embodiment 1, the front air duct 23 and the rear air duct 13 are replaced with a central diaphragm column 5 provided in the hollow cavity 6 of the near - lip - end plugging device II. The central diaphragm column 5 is a hollow cylinder with a transverse partition inside. The transverse partition divides the entire near - lip - end plugging device II into two parts, a front cavity 61 and a rear cavity 62 from the middle. The transverse partition has ventilation holes 51. The central diaphragm column 5 is in interference fit connection with the cup-shaped rear plugging member 1 and the cup-shaped front plugging member 2 at the middle annular concave platforms A and C, and forms a complete near - lip - end plugging device II after being assembled together.

[0111] The cigarette rod structure provided in this embodiment is as Figure 6 shown: It includes the aerosol - generating article described above and a cigarette tube inserted into the aerosol - generating article. The aerosol - generating article has an insertion part for inserting into the cigarette tube. The cigarette tube contains a cooling section III and a filtering section IV.

[0112] Embodiment 4

[0113] As Figure 7 The aerosol-generated product shown differs from that in Example 3 in that the specific structure of the petal core 4 is as follows:

[0114] The petal core 4 comprises: eight spaced-apart stiffeners 42 and eight cylindrical heads 41. Each stiffener 42 is connected to one head 41 at each end. Each head 41 is also connected to two stiffeners 42. The eight stiffeners 42 and the eight heads 41 are interconnected to form a circular or polygonal perimeter.

[0115] Each cylindrical end cap 41 is positioned correctly in the middle of the inlet 21 or outlet 11 to achieve a balance: an annular gap with a spacing smaller than the average particle size of the particulate smoke-generating material is formed between the outer wall of the end cap 41 and the inner wall of the inlet 21 or outlet 11. The annular gap serves as an airflow channel.
