Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, specifically to an aerosol matrix structure. Background Technology

[0002] Aerosol matrix structures typically require an aerosol generation device for use. This device includes a heating chamber into which the aerosol matrix structure is inserted. The heating chamber heats the aerosol matrix structure, causing it to generate aerosols for user consumption. However, this heating method, requiring an aerosol generation device, is inconvenient, and users must carry both the aerosol matrix structure and the device, resulting in a poor user experience. Utility Model Content

[0003] This application provides an aerosol matrix structure that solves the problems of inconvenient heating and poor user experience associated with aerosol matrix structures.

[0004] To address the aforementioned technical problems, this application provides an aerosol matrix structure, including a matrix segment and a heating structure. The matrix segment contains an aerosol matrix, which generates aerosols upon heating. The heating structure includes an outer shell and a partition, with the partition disposed within the outer shell to divide the internal space of the outer shell into a first accommodating cavity and a second accommodating cavity. A first solid reactant is disposed in the first accommodating cavity, and a second solid reactant is disposed in the second accommodating cavity. The first solid reactant reacts exothermically with the second solid reactant after the partition is damaged, and the heat generated by the exothermic reaction is used to heat the aerosol matrix.

[0005] In one embodiment, the heating structure is in contact with the matrix segment, and the heating structure is disposed inside the matrix segment.

[0006] In one embodiment, the substrate segment has a tubular structure with an installation cavity inside. The heating structure is disposed inside the installation cavity, and the outer wall of the outer shell is attached to the inner wall of the installation cavity. The central axis of the heating structure coincides with the central axis of the tubular structure.

[0007] In one embodiment, the first accommodating cavity and the second accommodating cavity are arranged side by side along the radial direction of the matrix segment.

[0008] In one embodiment, the first solid reactant is aluminum powder and the second solid reactant is iron oxide; or, the first solid reactant is calcium and the second solid reactant is copper oxide.

[0009] In one embodiment, the housing includes a first housing and a second housing that are sealed together, with a partition sandwiched between the first housing and the second housing.

[0010] In one embodiment, the housing is configured as a metal housing with a thickness of 0.02 mm to 0.08 mm.

[0011] In one embodiment, the spacer is configured as a polyimide film.

[0012] In one embodiment, the aerosol matrix further includes a nozzle section, a cooling section, and a sealing section. The nozzle section, cooling section, matrix section, and sealing section are connected sequentially along the axial direction of the matrix section. The cooling section has a cooling channel, and the inner wall of the cooling channel is provided with a cooling hole communicating with the outside of the cooling section.

[0013] In one embodiment, the radial dimension of the housing is smaller than the radial dimension of the cooling channel.

[0014] This application provides an aerosol matrix structure, including a matrix segment and a heating structure. The matrix segment contains an aerosol matrix, which generates aerosols upon heating. The heating structure includes an outer shell and a partition. The partition is disposed within the outer shell to divide the internal space of the outer shell into two independent accommodating cavities: a first accommodating cavity and a second accommodating cavity. The first accommodating cavity contains a first solid reactant, and the second accommodating cavity contains a second solid reactant. The first solid reactant reacts exothermically with the second solid reactant after the partition is damaged, and the heat generated by the exothermic reaction is used to heat the aerosol matrix. By incorporating a heating structure within the aerosol matrix structure, the first solid reactant within the heating structure can react exothermically with the second solid reactant after the partition is damaged, and the heat generated by the exothermic reaction is used to heat the aerosol matrix. Therefore, when aspirating the aerosol matrix structure, the user does not need to use an aerosol generating device for heating; only the heating structure within the aerosol matrix structure is needed to heat the aerosol matrix. This eliminates the need to carry an additional aerosol generating device, improving the user experience. Furthermore, the first and second solid reactants of the heating structure inside the aerosol matrix are separated by a partition. During use, it is only necessary to break the partition by squeezing to allow the first and second solid reactants to undergo an exothermic reaction, which is quite convenient to use.

For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0020] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0023] like Figure 1-3 As shown, this application provides an aerosol matrix structure 10, which includes a matrix segment 11 and a heating structure 12. The aerosol matrix structure 10 is generally a cylindrical structure with a circular cross-section; in one specific embodiment, the aerosol matrix structure 10 is cylindrical. Thus, the aerosol matrix structure 10 has a central axis. It is understood that the shape and size of the aerosol matrix structure 10 are not limited, and the cross-section of the aerosol matrix structure 10 can also be elliptical, rectangular, or other regular or irregular shapes.

[0024] The matrix segment 11 contains an aerosol matrix, which is used to generate aerosols upon heating. In one embodiment, the matrix segment 11 further includes a coating layer that surrounds the aerosol matrix to form the outer wall of the matrix segment 11. The aerosol matrix is ​​prepared from tobacco, herbal or plant leaves, or pharmaceuticals as the main solid raw materials, and includes one or more of the following forms: granules, flakes, powder fragments, filaments, pastes, cakes, porous aerogels, etc. It is understood that the materials forming the aerosol matrix are not limited; the aerosol matrix can be formed from a single material or from a mixture of multiple materials in different proportions. Other substances can also be added to the aerosol matrix to produce aerosols with different compositions and flavors to meet different user needs. The coating layer can be formed, for example, from a wrapping material such as paper, thereby maintaining a certain shape of the aerosol matrix. It is understood that the materials forming the coating layer are not limited to this; in other embodiments, the coating layer can also be formed from other materials such as aluminum foil to meet different requirements.

[0025] The heating structure 12 includes a housing 121 and a partition 122. The partition 122 is disposed within the housing 121 to divide the internal space of the housing 121 into two independent accommodating cavities: a first accommodating cavity 123 and a second accommodating cavity 124. That is, when not in use, the first accommodating cavity 123 and the second accommodating cavity 124 are not connected and are two independent spaces. The housing 121 can be made of a thin but durable material with high thermal conductivity and high temperature resistance. For example, in one embodiment, the housing 121 is configured as a metal housing with a thickness of 0.02mm-0.08mm. Metal has high ductility, making it less likely to damage the housing 121 when the user breaks the partition 122. Furthermore, metal can be made into a thinner housing 121 to reduce heat loss due to the thickness of the housing 121 itself. In addition, metal has high thermal conductivity and can withstand certain high temperatures, thus making it an optimal material for the housing 121. Since the user needs to squeeze the partition 122 from the outside of the outer shell 121 into the inside of the outer shell 121, the outer shell 121 is configured as a soft shell that can deform when subjected to external pressure.

[0026] In one embodiment, the outer casing 121 includes a first casing and a second casing that are sealed together, with a partition 122 sandwiched between the first casing and the second casing. Specifically, the first casing has a first slot, and the second casing has a second slot. The first slot of the first casing mates with the partition 122 to form a first receiving cavity 123, and the second slot of the second casing mates with the partition 122 to form a second receiving cavity 124. The partition can be sandwiched between the first casing and the second casing, and then the first casing and the second casing can be welded together to achieve the connection between the outer casing 121 and the partition 122. This assembly method is simple and efficient, and is suitable for manufacturing on automated production lines.

[0027] The partition 122 is typically made of a different material than the outer shell 121 and is easily damaged. For example, in one embodiment, the partition 122 is configured as a polyimide film. Thus, when a user applies force to the heating structure 12, the partition 122 is easily damaged, allowing the first accommodating cavity 123 and the second accommodating cavity 124 to communicate.

[0028] The first accommodating cavity 123 contains a first solid reactant, and the second accommodating cavity 124 contains a second solid reactant. The first solid reactant reacts with the second solid reactant in an exothermic reaction after the partition 122 is damaged. The heat generated by the exothermic reaction is used to heat the aerosol matrix. For example, in one embodiment, the first solid reactant is aluminum powder and the second solid reactant is iron oxide; or, the first solid reactant is calcium and the second solid reactant is copper oxide. The first and second solid reactants can be single substances or can be a mixture of at least two non-reactive substances.

[0029] This application does not specify the exact materials of the first and second solid reactants, as long as they can generate heat through an exothermic reaction upon contact. It should be noted that this application selects two solid reactants instead of liquid reactants because it is impossible to completely avoid damage to the outer shell during compression. If the outer shell breaks, the liquid reactant may easily leak out, and the aerosol matrix may be easily affected by the liquid reactant, ultimately leading to the aerosol generating odors or harmful substances. Preferably, at least one of the first and second solid reactants is a metal or a metal compound. Both the partition 122 and the outer shell 121 are made of materials that do not react with the first and second solid reactants.

[0030] This application incorporates a heating structure 12 within the aerosol matrix structure 10. The first solid reactant within the heating structure 12 can undergo an exothermic reaction with the second solid reactant after the partition 122 is broken. The heat generated by this exothermic reaction is used to heat the aerosol matrix. Therefore, when pumping the aerosol matrix structure 10, the user does not need to use an aerosol generating device for heating; the heating structure 12 within the aerosol matrix structure 10 is sufficient to heat the aerosol matrix. This eliminates the need for an additional aerosol generating device, improving the user experience. Furthermore, the first and second solid reactants within the heating structure 12 of the aerosol matrix structure 10 are separated by the partition 122. During use, simply squeezing the partition 122 breaks the partition, allowing the first and second solid reactants to undergo an exothermic reaction, making it convenient to use.

[0031] In one embodiment, the heating structure 12 is in contact with the matrix segment 11, and the heating structure 12 is disposed inside the matrix segment 11. By contacting the heating structure 12 with the matrix segment 11, the heat generated by the heating structure 12 can be transferred to the matrix segment 11 through the outer shell 121. When the heating structure 12 is disposed inside the matrix segment 11, the heat from the heating structure 12 can be transferred to the matrix segment 11 in the circumferential direction, achieving circumferential heating of the matrix segment 11. It should be noted that both the outer layer of the matrix segment 11 and the aerosol matrix inside the matrix segment are deformable materials under external force. Therefore, when the user squeezes the matrix segment from the outside, the force can be applied to the heating structure 12 inside the matrix segment 11.

[0032] In one embodiment, the substrate segment 11 has a tubular structure with an internal mounting cavity. The heating structure 12 is disposed within the mounting cavity, and the outer wall of the outer shell 121 is fitted against the inner wall of the mounting cavity. The central axis of the heating structure 12 coincides with the central axis of the tubular structure. By aligning the central axis of the heating structure 12 with the central axis of the tubular structure, the heating structure 12 can uniformly transfer heat to the substrate segment 11 in the circumferential direction, resulting in more uniform heating of the substrate segment 11. Of course, in other embodiments, the central axis of the heating structure 12 and the central axis of the tubular structure may intersect or be spaced apart.

[0033] In one embodiment, the first accommodating cavity 123 and the second accommodating cavity 124 are arranged side by side along the radial direction of the matrix segment 11, that is, the partition 122 extends along the axial direction to divide the internal space of the outer shell 121 into the first accommodating cavity 123 and the second accommodating cavity 124 arranged side by side in the radial direction.

[0034] In one embodiment, the aerosol matrix further includes a nozzle section 12, a cooling section 13, and a sealing section 14. The nozzle section 12, cooling section 13, matrix section 11, and sealing section 14 are sequentially connected along the axial direction of the matrix section 11. The nozzle section 12 primarily functions as a filter, allowing the user to inhale the aerosol. The nozzle section 12 may contain a filter medium that can filter tar, suspended particles, etc., from the aerosol, thereby reducing unwanted substances in the aerosol inhaled by the user. The filter medium can be, for example, a polylactic acid filament tow or a cellulose acetate filament tow.

[0035] The main function of the cooling section 13 is to reduce the temperature of the aerosol to prevent burns to the mouthpiece. The cooling section 13 has a cooling channel 131, and the inner wall of the cooling channel 131 has cooling holes 132 that communicate with the outside of the cooling section 13. After the aerosol is generated in the matrix section 11, it flows through the cooling channel 131 and eventually flows out from the mouthpiece section 12 for the user to inhale. When the aerosol passes through the cooling channel 131, cold air can enter the cooling channel 131 through the cooling holes 132 under negative pressure to mix with the aerosol and lower its temperature.

[0036] The material selection for cooling section 13 is one of the following: polylactic acid / aluminum foil composite film, paper filter rod, polylactic acid nonwoven fabric, polylactic acid granules, polylactic acid filament braided tube, serrated polylactic acid folded film, cellulose acetate, and cooling activated carbon composite material.

[0037] The cooling holes 132 can be circular, elliptical, rhomboid, or square, etc., and their shape should be selected based on the manufacturing process and cost of the aerosol matrix structure 10. Specifically, the larger the aperture of the cooling holes 132, the lower the airflow temperature within the aerosol matrix structure 10, resulting in a larger amount of aerosol being drawn in by the user and lower suction resistance. Therefore, the aperture size of the cooling holes 132 can be selected and set according to actual conditions. Of course, considering the supporting effect of the cooling section 13, the number and aperture size of the cooling holes 132 should be designed in conjunction with the diameter of the cooling section 13 to avoid the cooling section 13 from easily deforming and collapsing due to excessively large opening areas, thereby causing blockage of the cooling channel 131.

[0038] Preferably, in a specific embodiment, the number of cooling holes 132 is 4 to 10, all of which are circular in shape and evenly distributed in the circumferential direction of the cooling section 13. This design of the cooling holes 132 allows for a more sufficient amount of aerosol to be drawn in, with moderate suction resistance and a moderate airflow temperature, resulting in a better suction experience for the user.

[0039] The sealing section 14 is located at the end of the aerosol matrix structure 10, providing a physical support base to prevent aerosol matrix particles or materials from loosening or falling off during heating, maintaining the integrity of the aerosol matrix structure 10, and avoiding leakage due to thermal expansion or movement of the matrix section 11, which would affect the user experience. The sealing section 14 is not completely sealed, but has a structure with micropores that allow gas to pass through. The sealing section 14 primarily blocks large particles and absorbs liquids. External airflow enters the matrix section 11 through the micropores of the sealing section 14 under the user's suction, thus the sealing section 14 can perform preliminary filtration of the external airflow, intercepting dust or foreign objects in the environment. Furthermore, if condensate is generated in the cooling section 13 or the matrix section 11, the fiber structure of the sealing section 14 can prevent the liquid from flowing out of the aerosol matrix structure 10. In addition, the sealing section 14 can control airflow resistance through fiber density to ensure smooth suction. The material of the sealing section 14 can be, for example, polypropylene fiber, polyester fiber, cotton, or acetate fiber. In other embodiments, the aerosol matrix structure 10 may not have the cooling section 13 and / or the blocking section 14, or the aerosol matrix structure 10 may have other functional sections, which will not be described in detail here.

[0040] In one embodiment, the radial dimension of the outer shell 121 is smaller than the radial dimension of the cooling channel 131. Therefore, the matrix segment 11 surrounding the outer shell 121 allows aerosols generated by the matrix segment 11 to easily enter the cooling channel 131, preventing the outer shell 121 from blocking the cooling channel 131.

[0041] The above examples illustrate this application only to aid in understanding the invention and are not intended to limit the scope of the application. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the concept of this application.
