Abstract
Description
Technical Field
[0001] This application relates to the field of aerosol generation technology, specifically to an aerosol product. Background Technology
[0002] An aerosol generating device is a device that heats and atomizes aerosol products to generate aerosols. Aerosol products are typically cylindrical and include a matrix section, a filter section, and other structures. The aerosol product can be inserted into the heating chamber of the aerosol generating device, where the heating chamber heats the matrix section to generate aerosols.
[0003] When the matrix segments of the smoke-generating material in the form of thin-film matrix are aggregated and formed, the weight and density of the thin-film matrix are relatively large. Although this can ensure the total amount of aerosol, the gaps between the thin-film matrix are small, resulting in high suction resistance when the user inhales. Consequently, the amount of aerosol produced per breath is small, leading to a poor user experience. Utility Model Content
[0004] This application provides an aerosol product that can solve the problem of small aerosol volume during matrix segment suction, which leads to a poor user experience.
[0005] To solve the above-mentioned technical problems, this application provides an aerosol product, which includes a matrix segment, the matrix segment including a thin sheet matrix, the thin sheet matrix being aggregated to form a rod-shaped structure, and the thin sheet matrix having embossing, the embossing causing gaps to be formed between adjacent layers of the aggregated thin sheet matrix, and the embossing having an angle with the axis of the rod-shaped structure.
[0006] In one embodiment, the embossing consists of a plurality of straight, curved, or bent lines, or the embossing is a mesh pattern, or the embossing is an array pattern.
[0007] In one embodiment, the thickness of the sheet substrate is 1mm-3mm, and the depth of the embossing is 0.8mm-2.9mm.
[0008] In one embodiment, the matrix segment further includes a filamentous matrix and / or fragrance, the filamentous matrix and / or fragrance being dispersed on the surface of the sheet matrix and at least partially located within the gaps.
[0009] In one embodiment, the basis weight of the sheet matrix accounts for 65%-70% of the basis weight of the matrix segment;
[0010] And / or, the basis weight of the film matrix is not greater than 120 g / m³. 2 .
[0011] In one embodiment, the basis weight of the sheet matrix is less than 100 g / m³. 2 .
[0012] In one embodiment, the matrix segment includes a filamentous matrix with a width not exceeding 0.9 mm and a length of 1.5 mm to 2.5 mm.
[0013] And / or, the matrix segment includes fragrance, the fragrance having a mesh size of 150-300 mesh.
[0014] In one embodiment, the embossing includes first lines spaced apart in the width direction of the sheet substrate, wherein the spacing L between any two adjacent lines in the first lines is equal and L is less than 1 mm.
[0015] In one embodiment, the number of matrix segments is at least two, and the two matrix segments are arranged sequentially along the axis of the rod-shaped structure.
[0016] In one embodiment, the aerosol product further includes a filter section and a cooling section, wherein the filter section, the cooling section and the matrix section are arranged sequentially along the axial direction of the matrix section.
[0017] This application provides an aerosol product comprising a matrix segment, the matrix segment including a thin sheet matrix, the thin sheet matrix being rolled and agglomerated to form a rod-shaped structure, and the thin sheet matrix having embossing. The embossing creates gaps between adjacent layers of the agglomerated thin sheet matrix, and the embossing forms an angle with the axis of the rod-shaped structure. Because the aerosol product of this application is agglomerated into a rod-shaped structure by the thin sheet matrix, the embossing on the thin sheet matrix can create gaps between adjacent layers of the thin sheet matrix after the aerosol product is drawn. When a user inhales the aerosol product, the airflow can pass through the gaps between adjacent layers of the thin sheet matrix. In other words, the embossing of the thin sheet matrix can increase the overall porosity of the matrix segment, thereby reducing suction resistance during inhalation, increasing the amount of aerosol drawn, and improving the user experience.

Therefore, they should not be construed as limitations on the embodiments of this application.
[0030] like Figure 1 As shown, this application provides an aerosol product 10. Figure 1 The image shows an exploded view of each segment of the aerosol product 10. Generally, the segments of the aerosol product 10 are connected sequentially along an axial direction. The aerosol product 10 as a whole is approximately a rod-shaped structure with a circular cross-section; in one specific embodiment, the aerosol product 10 is cylindrical. Thus, the aerosol product 10 has a central axis. It is understood that the shape and size of the aerosol product 10 are not limited, and the cross-section of the aerosol product 10 can also be elliptical, rectangular, or other regular or irregular shapes.
[0031] The aerosol article 10 includes at least a matrix segment 20, wherein the matrix segment 20 contains a solid aerosol matrix for generating aerosols upon heating. In one embodiment, the aerosol article 10 further includes a coating layer surrounding the matrix segment 20. The aerosol matrix is primarily composed of tobacco, herbal or plant leaves, or medicinal materials. 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. The coating layer can be, for example, formed from a wrapping material such as paper, thereby maintaining the shape of the matrix segment 20. 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.
[0032] In one embodiment, the aerosol matrix further includes a filter section 30, a cooling section 40, and a sealing section 50. The filter section 30, cooling section 40, matrix section 20, and sealing section 50 are sequentially arranged along the axis of the matrix section 20. An encapsulation layer can further wrap around the outer peripheral surfaces of the filter section 30, cooling section 40, and sealing section 50. The filter section 30 primarily functions as a filter, allowing the user to inhale the aerosol. The filter section 30 may contain a filter medium that filters suspended particles and impurities within the aerosol, reducing unwanted substances inhaled by the user. The aerosol can also be further cooled by the filter medium. The filter medium can be, for example, a polylactic acid filament tow or a cellulose acetate filament tow.
[0033] The main function of the cooling section 40 is to reduce the temperature of the aerosol to prevent burns to the mouthpiece. The cooling section 40 contains a cooling channel, and the inner wall of the cooling channel has cooling holes 41 that communicate with the outside of the cooling section 40. After the aerosol is generated in the matrix section 20, it flows through the cooling channel and finally exits from the filter section 30 for the user to inhale. When the aerosol passes through the cooling channel, cold air can enter the cooling channel through the cooling holes 41 under negative pressure to mix with the aerosol and lower its temperature.
[0034] The material for the cooling section 40 can be selected from 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.
[0035] The sealing section 50 is located at the end of the aerosol product 10 and serves as a physical support base to prevent aerosol matrix particles or materials from loosening or falling off during heating, maintaining the integrity of the aerosol product 10. It also prevents leakage caused by thermal expansion or movement of the matrix section 20, thus avoiding impact on user experience. The sealing section 50 may not be completely sealed; instead, it has a structure with micropores that allow gas to pass through. The sealing section 50 primarily blocks large particles and absorbs liquids. External airflow enters the matrix section 20 through the micropores of the sealing section 50 under the user's suction. Therefore, the sealing section 50 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 40 or the matrix section 20, the fibrous structure of the sealing section 50 can prevent the liquid from flowing out of the aerosol product 10. Additionally, the sealing section 50 can control airflow resistance through fiber density to ensure smooth suction. The sealing section 50 can be made of materials such as polypropylene fiber, polyester fiber, cotton, or acetate fiber. In other embodiments, the aerosol article 10 may not have at least one of the cooling section 40, the sealing section 50, and the filter section 30, or the aerosol article 10 may have other functional sections, which will not be described in detail here.
[0036] The matrix segment 20 includes a sheet matrix 21, and the matrix segment 20 is mainly composed of the sheet matrix 21. The sheet matrix 21 refers to a sheet-like solid aerosol matrix, which can be formed by methods such as slurry processing, papermaking, and rolling. Generally, the thickness of the sheet matrix 21 is 1mm-3mm. Figure 2 As shown, the sheet substrate 21 is formed into a rod-shaped structure by aggregation. "Aggregation" can be achieved by winding or folding, or by applying a force from all sides to the center to the sheet substrate 21 to form a rod-shaped structure with aggregated folds. For example, the sheet substrate 21 can be a structure with a rectangular outer contour (e.g., Figure 3 ) coiled together to form a rod-shaped structure with an outer contour roughly cylindrical (e.g. Figure 2 Generally, the sheet matrix 21 is wound around the axis of the rod-shaped structure.
[0037] like Figure 3-6 As shown, the thin substrate 21 has embossing 211, which creates several crack gaps 213 on the thin substrate 21. The embossing 211 is formed approximately along the thickness direction of the thin substrate 21, and can completely penetrate the thin substrate 21, i.e., the depth of the embossing 211 is equal to the thickness of the thin substrate 21; or, the depth of the embossing 211 can be close to but slightly less than the depth of the thin substrate 21. For example, in one embodiment, the thickness of the thin substrate 21 is 1mm-3mm, and the depth of the embossing 211 is 0.8mm-2.9mm. Therefore, after cutting, the thin substrate 21 is prone to breakage at the embossing 211, and the thin substrate 21 as a whole has a structure that is partially broken but not completely severed. When it is gathered into a rod-shaped structure, some of the thin substrate 21 at the embossing 211 may break, while some of the thin substrate 21 at the embossing 211 may not be severed.
[0038] It is understandable that regardless of whether the embossing 211 penetrates the thin substrate 21, the embossing 211, formed on the thin substrate 21, will create several crack gaps 213 on the thin substrate 21. When the embossing 211 does not cut through the thin substrate 21, the crack gaps 213 are roughly groove-shaped gaps; when the embossing 211 cuts through the thin substrate 21, the crack gaps 213 become hollow structures on the thin substrate 21. Figure 2As shown, after the sheet matrix 21 aggregates to form a rod-shaped structure, the crack gap 213 formed by the embossing 211 allows adjacent layers of the aggregated sheet matrix 21 to form gaps 212 at the embossing 211. These adjacent layers can generally be adjacent layers along the radial direction of the matrix segment 20. Generally, the crack gap 213 connects the gaps 212 between adjacent layers. When the embossing 211 penetrates the thickness direction of the sheet matrix 21, the resulting crack gap 213 penetrates the thickness direction of the sheet matrix 21, thus creating communication between the gaps 212 on both sides of the thickness direction of the sheet matrix 21. This facilitates the radial diffusion and transport of aerosols in the matrix segment 20, increasing the aerosol diffusion path within the matrix segment 20.
[0039] Since the aerosol product 10 of this application is agglomerated into a rod-shaped structure by the thin sheet matrix 21, the embossing 211 on the thin sheet matrix 21 can form a number of crack gaps 213 on the thin sheet matrix 21, thereby forming gaps 212 between adjacent layers of the agglomerated thin sheet matrix 21. When the user inhales the aerosol product 10, the airflow can pass through the gaps 212 between adjacent layers of the thin sheet matrix 21. That is, the embossing 211 of the thin sheet matrix 21 can increase the overall porosity of the matrix segment 20, thereby reducing the suction resistance during inhalation, increasing the amount of aerosol during inhalation, and improving the user's experience.
[0040] The embossing 211 forms an angle with the axis of the rod-shaped structure. Compared with the case where the embossing 211 extends along the axis of the rod-shaped structure, that is, compared with the case where the embossing 211 is in a straight line, the oblique cutting of the embossing 211 can increase the length of the crack gap 213, thereby increasing the extension length of the gap 212, increasing the complexity of the embossing 211, and increasing the porosity of the matrix segment 20 to reduce the absorption resistance of the matrix segment 20.
[0041] In one embodiment, such as Figure 3 As shown, the embossing 211 can be several straight, curved, or bent lines, with the lines forming an angle with the axis of the rod-like structure, and the several lines are arranged in an orderly manner along the width direction W of the sheet matrix 21. It should be noted that, as Figure 2 As shown, the width direction W of the sheet substrate 21 described in this application is along the circumferential direction of the substrate segment 20, for example... Figure 2 and Figure 3 The arrow indicates the width direction W of the thin-film matrix 21. Figure 3 In one embodiment, several generally "S"-shaped lines are arranged at equal intervals along the width direction W of the sheet matrix 21. Figure 5 This is a schematic diagram of the thin substrate 21 cut according to the "S"-shaped embossing 211. Alternatively, in some embodiments, the embossing 211 is a mesh, formed by several straight, curved, or bent lines intersecting each other, with each line of the mesh forming an angle with the axis of the rod-shaped structure, and the mesh also having an ordered structure; or, as... Figure 4 As shown, embossing 211 is an array pattern, which is formed by arranging a minimum unit array. In this minimum unit, at least some of the lines have an angle with the axis of the rod-shaped structure. For example, in... Figure 4 In this embodiment, the dashed lines represent embossing 211, which is formed by an array of rhomboids, with the edges of the rhombuses forming an angle with the axis of the rod-shaped structure. If the embossing 211 completely penetrates the thin film matrix 21, then... Figure 4 The sheet matrix 21 of the embodiment may be in the form of Figure 6 The structure, that is, the embossing 211 is the outline of the hollowed-out pattern on the thin film substrate 21. Of course, the embossing 211 of this application is not limited to the shape described above, and can also be other shapes.
[0042] In one embodiment, such as Figure 5 and Figure 7 As shown, the matrix segment 20 also includes filamentous matrix 22 and / or fragrance 23. The filamentous matrix 22 and / or fragrance 23 are dispersed on the surface of the sheet matrix 21 and at least partially located within the gaps 212. That is, the filamentous matrix 22 and / or fragrance 23 of this application are not integrated when the aerosol matrix raw material is made into the sheet matrix 21, but are sprinkled on the sheet matrix 21 when the sheet matrix 21 is made into a rod-shaped structure. Specifically, the sheet matrix 21 is shaped and then the filamentous matrix 22 and / or fragrance 23 are sprinkled on its surface. Afterward, the sheet matrix 21 and the filamentous matrix 22 and / or fragrance 23 on its surface are aggregated together to form a rod-shaped structure. The embossing 211 on the sheet matrix 21 helps to limit the placement of powder, filamentous matrix 22 and other components, and helps to reduce the occurrence of powder, filamentous matrix 22 and other components falling off the sheet matrix 21. The additional filamentous matrix 22 and / or fragrance 23 added to the surface of the sheet matrix 21 are randomly and disorderly scattered on the sheet matrix 21.
[0043] In one embodiment, the basis weight of the sheet matrix 21 accounts for 65%-70% of the basis weight of the matrix segment 20, for example, 65%, 66%, 67%, 68%, 69%, or 70%. Other components located on the surface of the sheet matrix 21, such as the filamentous matrix 22 and / or fragrance 23, account for 30%-35% of the basis weight of the matrix segment 20, for example, 30%, 31%, 32%, 33%, 34%, or 35%.
[0044] In one embodiment, the basis weight of the sheet matrix 21 is no greater than 120 g / m³. 2 Preferably, the basis weight of the sheet matrix 21 is less than 100 g / m³. 2By reducing the proportion and thickness of the flake matrix 21, the problem of poor heat transfer within the matrix segment 20 when the flake matrix 21 is too large or too thick can be prevented. Some existing matrix segments 20 are formed entirely of flake matrix 21, resulting in poor heat transfer and slow heating efficiency. If the matrix segment 20 is formed entirely of particles, the porosity of the matrix segment 20 will be too large, easily causing heat loss and reduced energy utilization, and the basis weight of the matrix material will be insufficient. If the matrix segment 20 is entirely filamentous, it will easily lead to insufficient basis weight of the matrix material and insufficient total aerosol volume. In this embodiment, the matrix segment 20 mainly uses flake matrix 21, with other components as secondary components. The shape of the flake matrix 21 is changed by embossing 211, and the thickness of the flake matrix 21 is reduced. This can increase the thermal conductivity of the matrix segment 20 while taking into account the basis weight of the matrix material, which is conducive to more fully stimulating aroma and ensuring the amount of aerosol.
[0045] In one embodiment, the filamentous matrix 22 can be a natural filamentous aerosol matrix or a sheet matrix 21 cut into filaments. The width of the filamentous matrix 22 is no more than 0.9 mm, and the length of the filamentous matrix 22 is 1.5 mm to 2.5 mm, preferably 2 mm.
[0046] In one embodiment, the fragrance 23 has a mesh size of 150-300 mesh and a certain degree of fluidity, allowing it to be evenly sprinkled onto the sheet matrix 21 when it is agglomerated into a rod. The fragrance 23 includes, but is not limited to, one or more of plant powder extracts, monomeric absorbent powder fragrances, pulverized powder fragrances, and microcapsule powder fragrances.
[0047] In one embodiment, such as Figure 3 As shown, the embossing 211 includes first lines arranged at intervals in the width direction W of the sheet substrate 21, wherein the spacing L between any two adjacent lines in the first lines is equal and L is less than 1 mm.
[0048] In one embodiment, such as Figure 1 As shown, the number of matrix segments 20 is at least two. The two matrix segments 20 are arranged sequentially along the axis of the rod-shaped structure. The two matrix segments 20 can be two structures formed by cutting along the radial direction after the sheet matrix 21 is assembled and formed, or they can be pre-formed by embossing along the width direction W of the sheet matrix 21 before assembly and forming. The two matrix segments 20 are arranged sequentially along the axis of the rod-shaped structure to form an integral matrix segment 20.
[0049] 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.
