Description

Technical Field

[0001] This application relates to the field of novel tobacco heating products, and in particular to a solid-liquid dual-phase aerosol matrix heating product. Background Technology

[0002] Existing novel heated tobacco aerosol products primarily involve heating liquids and solids. Liquid aerosols offer significantly higher smoke generation per unit volume and greater consistency in flavor per puff compared to solid aerosols, but lack the authentic tobacco aroma and satisfaction, and suffer from severe condensation. Solid aerosols often employ a single solid tobacco matrix (i.e., a solid-phase aerosol matrix), resulting in insufficient smoke generation, a dry mouthfeel, and inconsistent aroma release, leading to inconsistent flavors per puff. While many studies have proposed combining the two, liquid aerosol matrices require rapid heating and cooling to generate aerosols, while solid tobacco matrices require accumulated heat to produce them. Currently, products that combine the two involve heating the liquid aerosol matrix and solid tobacco matrix separately in independent chambers, then mixing the resulting aerosols in the airway near the mouthpiece. However, as mentioned above, the conditions for aerosol generation differ between the two matrices; simply mixing and layering the two aerosols randomly results in inconsistent user experience. Summary of the Invention

[0003] This invention provides a solid-liquid two-phase aerosol matrix heating product to solve the technical problem in the prior art that liquid phase aerosol matrix and solid phase tobacco matrix are difficult to synergistically improve smoking flavor due to different aerosol generation conditions.

[0004] To achieve the above objectives, the technical solution provided by the present invention is as follows: In a first aspect, the present invention provides a solid-liquid two-phase aerosol matrix heating article, comprising a base, a shell, a heating element, a solid aerosol matrix, a liquid aerosol assembly, a liquid guiding element, and a nozzle. The heating element is disposed on the base and located inside the shell. The base, the shell, and the nozzle are sequentially connected. The shell encloses a first chamber near the base and a second chamber away from the base. The solid aerosol matrix fills the first chamber. The liquid guiding element and the liquid aerosol assembly are sequentially disposed in the second chamber. The heating element extends into the solid aerosol matrix. The liquid guiding element abuts against the liquid aerosol assembly and the solid aerosol matrix respectively, so that the liquid aerosol matrix migrates to the first chamber through the liquid guiding element under the action of a thermal gradient and / or negative pressure and forms an aerosol after heating. An airflow channel is provided in the liquid aerosol assembly so that the aerosol flows to the nozzle through the airflow channel.

[0005] Furthermore, the liquid aerosol assembly includes an inner shell, a liquid storage capillary, and sealing elements. The inner shell is disposed within the second chamber, and the sealing elements are respectively disposed at both ends of the inner shell. The liquid storage capillary is disposed between the two sealing elements, and the liquid aerosol matrix is ​​stored within the liquid storage capillary. The airflow channel penetrates the sealing elements and the liquid storage capillary to connect the solid aerosol matrix and the nozzle. The liquid guiding element is disposed between the solid aerosol matrix and the liquid storage capillary to facilitate the migration of the liquid aerosol matrix.

[0006] Furthermore, the liquid storage capillary is a filament bundle, with its two ends respectively abutting against the corresponding sealing element; the airflow channel is an air guide tube, which is disposed inside the inner shell and passes through the two sealing elements to connect the solid aerosol matrix and the nozzle; the filament bundle covers the periphery of the air guide tube.

[0007] Furthermore, the filament bundle is selected from natural cotton or chemical fibers.

[0008] Furthermore, the liquid guiding element includes a first capillary liquid guiding element and a liquid guiding mesh. The liquid guiding mesh is disposed between the seal near the base and the solid aerosol matrix. One end of the first capillary liquid guiding element passes through the seal near the base and abuts against the filament bundle, while the other end abuts against the liquid guiding mesh to transport the liquid aerosol matrix.

[0009] Furthermore, the liquid guiding mesh is arranged perpendicular to the axial direction of the air guiding pipe and is connected to the air guiding pipe.

[0010] Furthermore, the material of the first capillary fluid is selected from one or more of linen, non-woven fabric, and aramid.

[0011] Furthermore, the liquid guiding mesh is selected from one or more of metal sheets, tobacco sheets, and reconstituted tobacco sheets.

[0012] Furthermore, the thickness of the liquid guiding mesh is 0.05mm to 0.3mm.

[0013] Furthermore, the liquid storage capillary is a porous structure, with one end abutting against the sealing element near the suction nozzle and the other end abutting against the liquid guiding element; the airflow channel is formed within the porous structure.

[0014] Furthermore, the porous structural component is selected from one or more of porous ceramics, metal felt, and porous metals.

[0015] Furthermore, the liquid guiding element includes a second capillary liquid guiding element, one end of which abuts against the porous structure and the other end of which abuts against the solid aerosol matrix.

[0016] Furthermore, the material of the second capillary fluid is selected from one or more of linen, non-woven fabric, and aramid.

[0017] Furthermore, the thickness of the second capillary fluid is 0.3 mm to 3 mm.

[0018] Furthermore, the distance between the end of the liquid phase aerosol component near the base and the heating element is less than or equal to 1 mm.

[0019] Furthermore, the liquid-phase aerosol matrix is ​​selected from one or more of propylene glycol, glycerol, and plant extracts.

[0020] The solid-liquid two-phase aerosol matrix heating product provided by this invention allows the liquid aerosol matrix to migrate towards the heating element when the heating element is heated but not inhaled. This enables controlled and slow replenishment of the liquid aerosol matrix, preventing excessive flow of the liquid aerosol matrix to the solid aerosol matrix and excessive wetting, which would weaken the tobacco aroma. During inhalation, the airflow moves from the base towards the mouthpiece, and the liquid aerosol matrix accelerates its displacement towards the heating element under the negative pressure of inhalation, at a speed greater than that when not inhaled, ensuring timely replenishment of the liquid aerosol matrix during inhalation.

[0021] The aforementioned solid-liquid two-phase aerosol matrix heating products utilize the effects of thermal gradient and suction negative pressure to allow the liquid-phase aerosol matrix to migrate and replenish the solid-phase aerosol matrix during suction, thereby improving the taste. The solid and liquid matrices work synergistically to produce ample smoke, emphasizing the natural aroma of tobacco and a satisfying experience, while the liquid-phase aerosol matrix enhances the vapor production. The orderly and stable delivery of aerosols with consistent flavor by the solid and liquid matrices further improves the user's smoking experience. Attached Figure Description

[0029] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this application can be implemented.

[0030] like Figures 1 to 3 As shown in the illustration, this application provides a solid-liquid two-phase aerosol matrix heating product, including a base 10, a shell 20, a heating element 30, a solid aerosol matrix 50, a liquid aerosol assembly 60, a liquid guiding element, and a nozzle 40. The heating element 30 is disposed on the base 10 and located inside the shell 20. The base 10, the shell 20, and the nozzle 40 are connected in sequence. The shell 20 encloses a first chamber near the base 10 and a second chamber away from the base 10. The solid aerosol matrix 50 fills the first chamber; the liquid guiding element and the liquid aerosol assembly 60 are sequentially disposed in the second chamber, and the heating element 30 extends into the solid aerosol matrix 50. The liquid guiding element abuts against the liquid aerosol assembly 60 and the solid aerosol matrix 50 respectively, so that the liquid aerosol matrix migrates to the first chamber through the liquid guiding element under the action of thermal gradient and / or negative pressure and forms an aerosol after heating. An airflow channel is provided inside the liquid phase aerosol assembly 60 so that the aerosol flows through the airflow channel to the nozzle 40.

[0031] In this embodiment, the solid aerosol matrix 50 is disposed in the first chamber, and the heating element 30 is fixed on the base 10. The heating element 30 extends into the solid aerosol matrix 50 to heat it. The liquid aerosol assembly 60 is disposed in the second chamber, and the liquid aerosol assembly 60 abuts against the solid aerosol matrix 50. When the heating element 30 heats the solid aerosol matrix, it allows the liquid aerosol matrix to migrate into the first chamber.

[0032] In this embodiment, when the heating element 30 is energized, the temperature of the solid aerosol matrix 50 is higher than that of the liquid aerosol assembly 60, forming an axial thermal gradient from the solid aerosol matrix 50 to the liquid aerosol assembly 60. When not inhaling, this axial thermal gradient releases the liquid aerosol assembly 60 from the liquid aerosol matrix, allowing it to migrate towards the first chamber. This achieves controlled and slow replenishment of the liquid aerosol matrix, preventing excessive flow of liquid aerosol matrix towards the solid aerosol matrix 50 and its excessive wetting, which would weaken the tobacco aroma. During inhalation, the airflow flows from the base 10 through the first and second chambers towards the mouthpiece 40, creating a negative pressure in the first chamber. Under this negative pressure, the liquid aerosol matrix accelerates its displacement towards the heating element 30 at a speed greater than when not inhaling, ensuring timely replenishment of the liquid aerosol matrix during inhalation. Different suction forces result in different speeds. A stronger suction force leads to greater consumption of the solid phase aerosol matrix 50 and a faster migration speed of the liquid phase aerosol matrix, ensuring that the content of each component in the aerosol generated from the aerosol product is consistent.

[0033] In this embodiment, the heating element 30 can be an etched heating element 30 formed by etching conductive traces onto a thin-walled metal sheet, with a thickness of 0.05mm to 0.3mm. The heating element 30 can be arranged as a single piece or in a symmetrical / asymmetrical arrangement of multiple pieces. The heating element 30 can be made of materials such as stainless steel (SUS316L, SUS304, SUS304H), iron-chromium-aluminum, chromium-nickel-iron, and nickel-chromium to achieve low-cost mass production. The heating traces of the etched heating element 30 can be serpentine, mesh-like, or concentric circles to achieve uniform surface heating. The two ends of the conductive traces of the heating element 30 are exposed at the end of the base 10 and bent to serve as electrodes for connecting the heating device.

[0034] In this embodiment, the solid aerosol matrix 50 is tobacco particles, porous tobacco blocks, or molded material. It can be directly filled and molded. The heating area of ​​the heating element 30 is completely placed inside or closely adjacent to the solid aerosol matrix 50 to achieve surface heating. When the solid aerosol matrix 50 is made of particles, the particle size is between 0.3 and 1.2 mm; if porous tobacco blocks or molded materials are used, the particle size is preferably between 40% and 70% to ensure airflow and adsorption of the liquid aerosol matrix. Specifically, the liquid aerosol matrix is ​​selected from one or more of propylene glycol, glycerol, and plant extracts.

[0035] In some embodiments, the liquid aerosol assembly 60 includes an inner shell 61, a liquid storage capillary 62, and a sealing element 64. The inner shell 61 is disposed in the second chamber, and the sealing elements 64 are respectively disposed at both ends of the inner shell 61. The liquid storage capillary 62 is disposed between the two sealing elements 64, and the liquid aerosol matrix is ​​stored in the liquid storage capillary 62. An airflow channel passes through the liquid storage capillary 62 and the sealing element 64 to connect the solid aerosol matrix 50 and the nozzle 40. A liquid guiding element is disposed between the solid aerosol matrix 50 and the liquid storage capillary 62 to control the migration of the liquid aerosol matrix.

[0036] In this embodiment, the airflow channel penetrates the inner shell 61 and two seals 64, serving as an axial channel for the aerosol, allowing the inner shell 61 to communicate with the solid aerosol matrix 50 and the suction nozzle 40 respectively. A liquid-storing capillary 62 is filled between the airflow channel and the inner shell 61 to adsorb and store the liquid aerosol matrix, serving as the first-level control of the liquid aerosol matrix. The seals 64 at both ends of the inner shell 61 ensure a leak-proof seal. A liquid-guiding element is used for the axial transport of the liquid aerosol matrix, serving as the second-level control of the liquid aerosol matrix, and together with the first-level control, regulates the migration speed of the liquid aerosol matrix towards the heating element 30.

[0037] Specifically, in some embodiments, the liquid storage capillary 62 is a filament bundle, with its two ends abutting against the corresponding seals 64; the airflow channel is an air guide tube 63, which is disposed inside the inner shell 61 and passes through the two seals 64 to connect the solid aerosol matrix 50 and the nozzle 40; the filament bundle covers the periphery of the air guide tube 63. The filament bundle is selected from natural cotton or chemical fibers. That is to say, the liquid storage capillary 62 can be a filament bundle, in which case it fills as much of the space between the air guide tube 63 and the inner shell 61 as possible to store more liquid aerosol matrix, thereby working in conjunction with the solid aerosol matrix 50 to provide an orderly and stable aerosol with consistent flavor; and the two ends of the filament bundle abut against the seals 64, without directly contacting the solid aerosol matrix 50.

[0038] The liquid guiding element includes a first capillary liquid guiding 65 and a liquid guiding mesh 66. The liquid guiding mesh 66 is disposed between the sealing member 64 near the base 10 and the solid aerosol matrix 50. One end of the first capillary liquid guiding 65 passes through the sealing member 64 near the base 10 and abuts against the filament bundle, while the other end abuts against the liquid guiding mesh 66 to transmit the liquid aerosol matrix.

[0039] In this embodiment, the first capillary liquid guide 65 extends longitudinally within the seal 64 and abuts against the filament bundle and the liquid guide mesh 66, thereby allowing the liquid aerosol matrix to migrate from the filament bundle to the liquid guide mesh 66 and be transported towards the heating element 30 via the liquid guide mesh 66. The liquid guide mesh 66 establishes a flow space between the first capillary liquid guide 65 and the solid aerosol matrix 50. The liquid aerosol matrix can diffuse axially and radially above the solid aerosol matrix 50 along the liquid guide mesh 66; simultaneously, the liquid guide mesh 66 confines the solid aerosol matrix 50 within the first chamber, achieving controllable conduction and uniform distribution of the liquid aerosol matrix. Preferably, the liquid guide mesh 66 is arranged perpendicular to the axial direction of the air guide tube 63 and communicates with the air guide tube 63. That is, at least a portion of the liquid guide mesh 66 communicates with the air guide tube 63 to facilitate the flow of aerosol to the suction nozzle 40.

[0040] Specifically, the material of the first capillary liquid guide 65 is selected from one or more of linen, non-woven fabric, and aramid. The liquid guide mesh 66 is selected from one or more of metal sheet, tobacco sheet, and reconstituted tobacco sheet. The seal 64 is made of silicone and connects the gas guide tube 63 and the inner shell 61. The space formed by the seal 64 is filled with filament bundles for adsorbing the liquid-phase aerosol matrix. The silicone seal 64 not only fixes the gas guide tube 63 and the filament bundles, but its elastic deformation can also absorb assembly tolerances, ensuring the sealing of the gas and liquid paths. The thickness of the liquid guide mesh 66 is 0.05mm to 0.3mm.

[0041] In this embodiment, after power is applied, the heating element 30 heats up, and the average temperature of the solid aerosol matrix 50 rises to 300℃~350℃, heating the solid aerosol matrix 50 and releasing tobacco aroma components. The temperature of the solid aerosol matrix 50 is higher than that of the liquid aerosol assembly 60, and the temperature gradually decreases towards the mouthpiece 40, forming an axial thermal gradient. When the user is not inhaling, this thermal gradient acts to unlock the liquid aerosol matrix, controlling it to move slowly along the first capillary liquid guide 65 and the liquid guide mesh 66 towards the heating element 30, preventing leakage and over-wetting in the non-inhaling state.

[0042] During suction, the airflow flows through the air guide tube 63 of the base 10, solid aerosol matrix 50, and liquid aerosol assembly 60 to the suction nozzle 40, as shown in the reference. Figure 3 A negative pressure difference is created within the product, further accelerating the migration of the liquid aerosol matrix towards the heating element 30. Upon reaching the high-temperature zone, the liquid aerosol matrix is ​​instantly atomized, fully mixing with the aroma released from the heated solid aerosol matrix 50 to form a stable and sufficient aerosol. This aerosol is then output from the nozzle 40 via the gas guide tube 63, achieving synergistic solid-liquid two-phase smoke generation. Due to the suction negative pressure, the liquid aerosol matrix rapidly moves towards the solid aerosol portion to compensate for the negative pressure, achieving pressure balance.

[0043] After the suction ends, the negative pressure disappears, and the thermal gradient becomes the dominant factor again, slowing down the migration rate of the liquid aerosol matrix. After the temperature drops to room temperature, the thermal gradient disappears, and the liquid aerosol matrix is ​​locked back by the storage capillary 62.

[0044] In extreme usage scenarios with low suction frequency, the liquid flow caused by the thermal gradient is faster than at room temperature, which will still exceed the pore adsorption limit of the solid aerosol matrix 50. This can be prevented by the adsorption cotton 70 of the base 10 adsorbing and retaining the liquid, forming a controlled mechanism of "rapid replenishment during suction, slowing down during non-suction, and overloaded adsorption cotton 70 retaining the liquid".

[0045] In other embodiments, reference is made to Figure 4 The liquid-storing capillary 62 is a porous structure, with one end abutting against the sealing element 64 near the suction nozzle 40 and the other end abutting against the liquid guiding element; an airflow channel is formed within the porous structure. The porous structure is selected from one or more of porous ceramics, metal felt, and porous metals. In this embodiment, the liquid-storing capillary 62 is a porous structure, with one end abutting against the liquid guiding element, through which the liquid-phase aerosol matrix is ​​transported. The aforementioned porous structure itself possesses excellent structural strength, high temperature resistance, strong capillary liquid-locking ability, and structural stability. It can withstand high temperatures up to 350°C and does not deform or pulverize after long-term use.

[0046] The liquid guiding element includes a second capillary liquid guiding element 67. One end of the second capillary liquid guiding element 67 abuts against the porous structure, and the other end abuts against the solid aerosol matrix 50. In this embodiment, in addition to its excellent liquid guiding and uniform liquid distribution functions, the second capillary liquid guiding element 67 also forms a structural fit with the porous structure and plays a buffering role. The second capillary liquid guiding element 67 adheres to the porous structure and the solid aerosol matrix 50, providing flexible buffer protection for the porous structure during assembly, transportation, and vibration during use, preventing the porous structure from damaging the solid aerosol matrix 50 due to compression; at the same time, it ensures that the liquid aerosol matrix is ​​uniformly transported to the heating element 30 along the second capillary liquid guiding element 67 without affecting the liquid guiding efficiency.

[0047] In some embodiments, the material of the second capillary liquid 67 is selected from one or more of linen, non-woven fabric, and aramid. In this embodiment, a soft second capillary liquid 67 is used in conjunction with the aforementioned porous structural component. On the one hand, it utilizes the capillary force of its fibers to achieve efficient liquid conduction; on the other hand, it can act as a flexible buffer interface, isolating the rigid porous structural component from the solid aerosol matrix 50 and the heating element 30. This effectively avoids the risk of the porous structural component breaking or the solid aerosol matrix 50 being crushed due to transportation vibration or user drops, significantly improving the product's drop resistance and shock resistance. Specifically, the thickness of the second capillary liquid 67 is 0.3 mm to 3 mm.

[0048] In this embodiment, after power is applied, the heating element 30 heats up, and the average temperature of the solid aerosol matrix 50 rises to 300℃~350℃, heating the solid aerosol matrix 50 and releasing tobacco aroma components. The temperature of the solid aerosol matrix 50 is higher than that of the liquid aerosol assembly 60, and the temperature gradually decreases towards the mouthpiece 40, forming an axial thermal gradient that drives the liquid aerosol matrix to move along the second capillary guide liquid towards the heating element 30. During inhalation, the airflow flows through the base 10, the solid aerosol matrix 50, and the air guide tube 63 of the liquid aerosol assembly 60 to the mouthpiece 40, creating a negative pressure difference within the product, further pulling the liquid aerosol matrix towards the heating element 30 region. After reaching the high-temperature zone, the liquid aerosol matrix is ​​vaporized and fully mixed with the aroma released by the heating of the solid aerosol matrix 50, forming a stable and sufficient aerosol, which is output from the mouthpiece 40 through the air guide tube 63, achieving synergistic solid-liquid dual-phase smoke generation. The second capillary fluid 67 simultaneously provides buffer protection for porous structural components, improving structural stability and reliability, and extending service life.

[0049] In some embodiments, the distance between the end of the liquid aerosol assembly 60 near the base 10 and the heating element 30 is less than or equal to 1 mm. In this embodiment, a portion of the heat radiated outward by the solid aerosol matrix 50 and the heating element 30 is absorbed by the liquid guiding element to preheat the transported liquid aerosol matrix. When the liquid aerosol matrix migrates to the vicinity of the heating element 30 to absorb heat and atomize, it already has a certain temperature and does not need to absorb too much heat. This allows the solid aerosol matrix 50 to maintain sufficient heat reserves, minimizing the impact on the subsequent continuous generation of aerosols from the solid aerosol matrix 50, and ensuring that the aerosol component content of each aerosol product remains essentially consistent.

[0050] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
