Abstract
Description
Technical Field
[0001] This invention relates to the field of aerosol generation technology, and more particularly to an aerosol product. Background Technology
[0002] In existing devices that use electrical energy to drive a heating element to convert an aerosol-generating matrix into aerosols, the aerosol-generating matrix is generally composed of disordered or ordered filaments similar to those in traditional cigarettes, with a circular cross-section, i.e., the commonly used rod-shaped cigarette. The heating element is a sheet-like or rod-like body with a certain structural strength, which is placed inside the aerosol-generating device. When the aerosol-generating matrix and the aerosol-generating device are used together, the heating element penetrates into the aerosol-generating matrix.
[0003] Currently, there are some drawbacks in the process of inserting heating elements into the aerosol generation matrix. On the one hand, it is difficult to ensure coaxiality between the heating element and the aerosol generation matrix during insertion. At the same time, the aerosol generation matrix needs to be set with a certain degree of looseness to allow the heating element to be inserted smoothly. The aforementioned looseness makes it difficult to ensure consistent adhesion between different parts of the aerosol generation matrix and the heating element. Both of these situations lead to uneven heat transfer. On the other hand, in order to ensure the strength of the heating element, a certain thickness is required. A larger heating element will absorb too much heat during heating, resulting in energy waste. Summary of the Invention
[0004] This invention provides an aerosol product to solve the technical problem in the prior art that the heat transfer of the aerosol generating matrix is uneven and the energy is wasted when heated in the appliance.
[0005] To achieve the above objectives, the technical solution provided by the present invention is as follows: The present invention provides an aerosol product, comprising a heating element and an aerosol generating matrix. The heating element is arranged in a planar shape, and the aerosol generating matrix is disposed on at least one side of the heating element. The aerosol generating matrix is in the form of a strip, which is stacked vertically and / or horizontally on the heating element.
[0006] Furthermore, the aerosol generating matrix includes a first strip, which is formed by multiple folds.
[0007] Furthermore, the aerosol generating matrix includes a plurality of second strips, which are laid flat and stacked to form the aerosol generating matrix.
[0008] Furthermore, the thickness of the heating element is 0.08 mm to 0.5 mm.
[0009] Furthermore, the width of the aerosol generating matrix is greater than or equal to 5 mm.
[0010] Furthermore, the thickness of the single-layer aerosol generating matrix is 0.07 mm to 0.25 mm.
[0011] Furthermore, the surface roughness of the aerosol generating matrix is 0.07 mm to 0.1 mm.
[0012] Furthermore, the aerosol product also includes a base and two electrodes, with the two ends of the heating element mounted on the base and the two electrodes respectively disposed at the ends of the heating element.
[0013] Furthermore, the aerosol-generating matrix on both sides of the heating element has the same thickness.
[0014] Furthermore, the angle between the length direction of the aerosol generating matrix and the axial direction of the heating element is greater than or equal to 0° and less than 10°.
[0015] The aerosol product provided by the present invention sets the aerosol generating matrix as a strip and stacks it on both sides of the planar heating element. There is no need for the heating element to be inserted into the generating matrix, and the two are matched in shape, which makes the heat transfer more uniform and improves the utilization rate of the aerosol generating matrix. In addition, the heating element is placed inside the aerosol generating matrix and can maintain its strength by relying on the generating matrix. There is no need to make it too thick to increase its own strength, which reduces its volume and energy consumption. Attached Figure Description

[0024] Reference Figure 1 , Figure 2This application provides an aerosol product, including a heating element 10 and an aerosol generating matrix 20. The heating element 10 is arranged in a planar shape, and the aerosol generating matrix 20 is disposed on at least one side of the heating element 10. The aerosol generating matrix 20 is strip-shaped and is stacked vertically and / or horizontally on the heating element 10.
[0025] In this embodiment, the heating element 10 is planar, and the aerosol generating matrix 20 is stacked on both sides of the heating element 10. "Strip-like" refers to a continuous shape with a certain width and length; the width of the strip is much greater than the width of the filamentous or strip-like elongated generating matrix commonly used in the prior art. Stacking includes two cases: one is that multiple layers of aerosol generating matrix 20 are stacked from bottom to top; the other is that a longer aerosol generating matrix 20 is folded, both of which can form a tobacco strip matching the size of the heating element 10. Vertical stacking means that after folding or stacking, the plane of each layer of aerosol generating matrix 20 is perpendicular to the plane of the heating element 10. Horizontal stacking means that after folding or stacking, the plane of each layer of aerosol generating matrix 20 is parallel to the plane of the heating element 10.
[0026] In this embodiment of the application, the number of first strips 21 and / or second strips 22 stacked vertically on a plane perpendicular to the plane where the heating element 10 is located on one side of the heating element 10 can be greater than one, and the number of first strips 21 and / or second strips 22 stacked horizontally on a plane parallel to the plane where the heating element 10 is located can also be greater than one.
[0027] Specifically, the aerosol generating matrix 20 includes a first strip 21, which is formed by multiple folds. (Refer to...) Figures 3 to 5 , Figure 3 This is a schematic diagram of the structure where the first strip 21 is horizontally folded on both sides of the heating element 10. Figure 5 This is a schematic diagram of the structure in which the first strip 21 is folded vertically on both sides of the heating element 10. Figure 4 This refers to the case where the first strip 21 is folded horizontally on one side of the heating element 10 and vertically on the other side. Figures 3 to 5 All folds in the text can be transformed into layers.
[0028] In other embodiments, the aerosol generating matrix 20 includes a plurality of second strips 22, which are laid flat and stacked to form the aerosol generating matrix 20. (See also...) Figure 6 Multiple second strip-shaped bodies 22 are laid flat and stacked together in sequence, i.e., layered.
[0029] In this embodiment, the structure of the aerosol generating matrix 20 on both sides of the heating element 10 can be both set as a first strip 21, or both set as a second strip 22, or one side can be set as a first strip 21 and the other side as a second strip 22; the same side of the heating element 10 can also be simultaneously provided with a first strip 21 and a second strip 22.
[0030] In some embodiments, the width of the aerosol generating matrix 20 is greater than or equal to 5 mm. That is, the width of the aerosol generating matrix 20 is greater than the diameter of a conventional stick cigarette. The width of the heating element 10 is slightly less than or equal to the width of the aerosol generating matrix 20. This dimensional matching ensures that the aerosol generating matrix 20 can absorb sufficient heat from the heating element 10 to generate aerosols.
[0031] In this embodiment, the aerosol generating matrix 20 can be made from mixed tobacco raw materials, or it can be a mixture of tobacco products coated onto the surface of tobacco paper, or a pore structure made of plant fibers, cellulose, or other materials filled with tobacco extract. The aforementioned mixed tobacco raw materials include at least a mixture of tobacco products and some alcohols, which can be glycerol and / or propylene glycol. The aforementioned mixed tobacco products are paper-like, granular, or filamentous materials reconstituted from tobacco powder. The aforementioned tobacco extract is a liquid or semi-solid substance extracted from tobacco materials, and contains at least nicotine.
[0032] In the aerosol product of this application embodiment, the heating element 10 is configured as a planar structure, and the aerosol generating matrix 20 is configured as a strip and stacked on both sides of the planar heating element 10. The length and width of the two are matched, which makes the heat transfer more uniform and improves the utilization rate of the aerosol generating matrix 20. In addition, the heating element 10 is placed inside the aerosol generating matrix 20, so there is no need for the heating element 10 to be inserted into the generating matrix. The strength requirement of the heating element 10 is low. The heating element 10 can maintain its strength by relying on the generating matrix. There is no need to make it too thick to increase its own strength, which reduces its volume and energy consumption.
[0033] In some embodiments, the thickness of the heating element 10 is 0.08 mm to 0.5 mm. In the embodiments of this application, the heating element 10 is configured as a thin sheet, preferably 0.08 mm to 0.1 mm thick. It does not require special mechanical strength. The heating element 10 is supported by the aerosol matrix 20, forming a high overall strength and avoiding deformation or breakage. The heating element 10 is made of a metallic material with a Curie temperature greater than 400°C, such as iron-chromium-aluminum, ferritic, or austenitic stainless steel. It also includes a thin sheet of insulating material (such as zirconium oxide, alumina, etc.) coated on the surface of the metallic material, and printed resistive circuitry.
[0034] In some embodiments, the aerosol article further includes a base 30 and two electrodes 40, with both ends of the heating element 10 mounted on the base 30, and the two electrodes 40 respectively disposed at the ends of the heating element 10. (Refer to...) Figure 2 The end of the heating element 10 is fixed inside the base 30, and two thin sheet termination ends are provided at the end of the heating element 10 to form electrodes 40; the rest of the heating element 10 is placed inside the aerosol generating matrix 20. When the aerosol product of this embodiment is placed into the aerosol device, the aerosol device can be connected to the aerosol product forming circuit through the connecting electrodes 40.
[0035] In this embodiment, the dimensions of the base 30 in the width and thickness directions of the aerosol product are substantially the same as those of the aerosol generating matrix 20. Both the cross-sectional shape of the base 30 and the cross-sectional shape of the aerosol generating matrix 20 can be rectangular. The end of the heating element 10 is inserted into the center position of the base 30 in the thickness direction, meaning the central axis of the base 30 coincides with the central axis of the heating element 10.
[0036] Furthermore, the aerosol-generating matrix 20 on both sides of the heating element 10 has the same thickness. (Refer to...) Figures 1 to 5 The aerosol generating matrix 20 has the same thickness on both sides of the heating element 10. When the aerosol matrices on both sides are stacked in the same way, they are arranged symmetrically, such as... Figure 3 .
[0037] In some embodiments, the angle between the length direction of the aerosol generating matrix 20 and the axial direction of the heating element 10 is greater than or equal to 0° and less than 10°. In the embodiments of this application, the angle between the length direction of the aerosol generating matrix 20 and the axial direction of the heating element 10 is kept small. On the one hand, this allows the aerosol generating matrix 20 to fully utilize the heat generated by the heating element 10. On the other hand, it reduces the resistance to airflow between the layers of the aerosol generating matrix 20. Especially in folded aerosol generating matrix 20, there are usually creases in the length direction. If the angle between the crease and the axial direction of the heating element 10 is too large, the crease will block the airflow path.
[0038] The surface of the stacked multilayer aerosol generating matrix 20 has a certain roughness, ensuring that even after folding or stacking, the gaps and roughness between adjacent matrix layers can still allow gas to pass through smoothly. Specifically, the surface roughness of the aerosol generating matrix 20 is 0.07 mm to 0.1 mm. The thickness of a single layer of aerosol generating matrix 20 is 0.07 mm to 0.25 mm.
[0039] The method for manufacturing an aerosol product according to an embodiment of this application includes the following steps: cutting tobacco raw materials into thin sheets into strips of aerosol generating matrix 20 of the required size; fixing a heating element 10 onto a base 30; and attaching the aerosol generating matrix 20 to both sides of the heating element 10 to form a cuboid-like aerosol product. The length of the aerosol product is preferably 15mm to 40mm, the width is preferably 10mm to 35mm, and the thickness is preferably 3mm to 8mm. The cross-section of the aerosol product along its length is approximately rectangular, as shown in the reference... Figure 1 Furthermore, it is permissible to have rounded corners with a rounded corner value greater than 0.1mm, or the four sides of the rectangle have a large arc that is close to a straight line and have rounded corners with a rounded corner value of 0.2mm to 2mm.
[0040] 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.
