Description

Technical Field

[0001] This application relates to the field of aerosol products technology, and in particular to a sandwich aerosol product. Background Technology

[0002] Currently, the mainstream known aerosol products are rod-shaped structures similar to traditional cigarettes, with their accompanying heating elements mainly falling into two categories: insertable and implantable. Regardless of the type of heating element, the contact area with the aerosol-generating matrix is ​​limited, and the time-temperature variation curves from the center point of the aerosol-generating matrix to various points on the outer surface gradually increase in difference. To ensure that the aerosol-generating matrix, even far from the heating element, can reach the suitable temperature range for aerosol generation, the temperature accumulated near the heating element will be significantly higher than the suitable temperature range, resulting in excessively large temperature differences at various points near the heating element. Summary of the Invention

[0003] This invention provides a sandwich-type aerosol product to solve the technical problem of large temperature differences at various locations of the aerosol generation matrix in existing aerosol products.

[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 sandwich-type aerosol article, comprising a heating element and an aerosol generating matrix, wherein the heating element is formed by folding a body in its length direction, the body being planar, the heating element comprising a plurality of folded planes, and gaps being formed between adjacent folded planes, and the aerosol generating matrix being folded and filled in some or all of the gaps.

[0005] Furthermore, at least two layers of the aerosol generating matrix are disposed between each pair of adjacent folded planes.

[0006] Furthermore, the included angle between any two adjacent folded planes is equal and ranges from 0° to 60°.

[0007] Furthermore, the length of each of the folded planes is equal.

[0008] Furthermore, the gap widths filled by the aerosol generating matrix located on the outer side of the main body are all equal, and the gap widths filled by the aerosol generating matrix located on the inner side of the main body are also all equal.

[0009] Furthermore, the thickness of the aerosol generating matrix is ​​0.1 mm to 0.4 mm.

[0010] Furthermore, the thickness of the body is 0.03mm to 0.1mm.

[0011] Furthermore, the material of the body is selected from one or more of iron-chromium-aluminum, stainless steel, and ferrite.

[0012] Furthermore, the width of the folded plane is less than or equal to the width of the folded aerosol-generating matrix.

[0013] Furthermore, the surface roughness of the aerosol generating matrix is ​​0.07 mm to 0.10 mm.

[0014] Furthermore, the bent section of the heating element and / or the bent section of the aerosol generating matrix are provided with through holes.

[0015] Furthermore, the sandwich-type aerosol product also includes a base and pins, with the pins respectively provided at both ends of the heating element, and the pins fixed on the base to electrically connect to the heating appliance.

[0016] The sandwich aerosol product provided by the present invention has a heating element body that is planar, which has a fast heating speed, significantly reduced energy consumption, and strong high-temperature stability. There is a large heat exchange area between the folded plane of the heating element and the folded aerosol generating matrix. The folded planes are opposite each other, and the heat radiation affects each other, which reduces the overall temperature difference in the area near the heating element.

[0025] like Figure 1 , Figure 2 As shown, this application provides a sandwich aerosol product, including a heating element 1 and an aerosol generating matrix 2. The heating element 1 is formed by folding a body along its length. The body is arranged in a planar shape. The heating element 1 includes a plurality of folded planes 11, and gaps are formed between adjacent folded planes 11. The aerosol generating matrix 2 is folded and filled in part or all of the gaps.

[0026] In this embodiment, the heating element 1 is formed by folding a body. The body is folded at a point along its length, meaning the bent section of the body is perpendicular to its length or at an angle to its length. The folded heating element 1 includes multiple folded planes 11. To bring the aerosol generating matrix 2 closer to the heating element 1, the aerosol generating matrix 2 is folded and filled into the gaps formed between the folded planes 11. The aerosol generating matrix 2 can be folded and filled on one side of the body on the heating element 1, or it can be folded and filled on both sides of the body on the heating element 1. For the same side of the body, the aerosol generating matrix 2 can be folded and filled into all the gaps, or it can be folded and filled into only part of the gaps.

[0027] Preferably, at least two layers of aerosol generating matrix 2 are provided between each pair of adjacent folded planes 11. That is, the aerosol generating matrix 2 is folded and filled on both sides of the main body of the heating element 1, and all gaps are filled, as shown in the figure. Figure 1 As shown, this results in aerosol generating matrix 2 being provided on both sides of each folded plane 11, improving the heat utilization rate of the heating element 1 and heating the aerosol generating matrix 2 more efficiently.

[0028] In this embodiment, the aerosol generating matrix 2 is folded and positioned along the extension direction of the folded body. The aerosol generating matrix 2 can be attached to the folded plane 11 of the heating element 1. Understandably, for the same folded aerosol generating matrix 2, the rounded corner of the end that wraps the heating element 1 inside is larger than the rounded corner of the end that is wrapped by the heating element 1. The thickness of the aerosol generating matrix 2 on both sides of the folded plane 11 can be equal or unequal.

[0029] In this embodiment, the aerosol generating matrix 2 can be in the form of a strip, facilitating its folding and filling of the aforementioned gaps. A strip refers to a shape with a certain width, continuous length, and the ability to extend. In this art, slender aerosol generating matrices 2, such as filaments or strips, are commonly used. Understandably, the width of the strip is much greater than the width of the filaments or strips. Specifically, the width of the aerosol generating matrix 2 is greater than 2 mm.

[0030] In this embodiment of the sandwich aerosol product, the heating element 1 has a planar body, resulting in rapid heating, significantly reduced energy consumption, and strong high-temperature stability. The folded plane 11 of the heating element 1 and the folded aerosol generating matrix 2 have a large heat exchange area. The folded planes 11 are opposite each other, and their heat radiation interacts, reducing the overall temperature difference in the vicinity of the heating element 1. In this embodiment, the body and the aerosol generating matrix 2 are closely fitted, providing a wide heating area, uniform baking, and improved utilization of the effective components in the aerosol generating matrix 2.

[0031] In some embodiments, the included angle between any two adjacent folded planes 11 is equal and ranges from 0° to 60°. In the embodiments of this application, the cross-sectional waveform of the heating element 1 resembles a sine curve. When the included angle between two adjacent folded planes 11 is 0°, all folded planes 11 of the heating element 1 are parallel, the thermal radiation interaction between the folded planes 11 is maximized, and the space utilization is also the highest.

[0032] The lengths of each folded plane 11 in the heating element 1 can be equal or unequal. Preferably, the lengths of each folded plane 11 are equal. In this embodiment, the heating element 1 is formed by folding the body. If the size of the body remains unchanged, the widths of the folded planes 11 are equal. If the lengths of the folded planes 11 are also equal, the areas of the folded planes 11 are equal, thus the heating heat of each folded plane 11 is the same, thereby making the heating of the aerosol generating matrix 2 more uniform.

[0033] In other embodiments, the gap widths filled by the aerosol generating matrix 2 located on the outer side of the body are all equal, and the gap widths filled by the aerosol generating matrix 2 located on the inner side of the body are also all equal.

[0034] Reference Figure 1 As can be seen, the inner and outer sides of the main body are folded and filled with aerosol generation matrix 2. The thickness of the two aerosol generation matrices 2 can be the same or different. Figure 1 The outer aerosol generating matrix 2 is thicker than the inner one. Specifically, the thickness of the aerosol generating matrix 2 is 0.1 mm to 0.4 mm. The gaps filled by the outer aerosol generating matrix 2 are all of equal width; the gaps filled by the inner aerosol generating matrix 2 are also all of equal width. That is to say, the gaps between the same folding plane 11 and two adjacent folding planes 11 can be equal or unequal, but the distances between folding planes 11 located on the same side of the body are equal.

[0035] In some embodiments, the thickness of the body is 0.03 mm to 0.1 mm. The material of the body is selected from one or more of iron-chromium-aluminum, stainless steel, and ferrite. In the embodiments of this application, the body is set as a thin sheet, which does not require special mechanical strength. The overall strength is formed by the aerosol-generated matrix 2, thereby avoiding deformation or breakage. The body material is a metallic material with a Curie temperature greater than 400°C.

[0036] In some embodiments, the width of the folded plane 11 is less than or equal to the width of the folded aerosol-generating matrix 2. (Refer to...) Figure 1The heating element and the aerosol generating matrix are folded and combined to form a sandwich-type aerosol product. The folded aerosol generating matrix has a surface parallel to the folding plane of the heating element, and its width is the width of the folded aerosol generating matrix. In this embodiment, the closer the width of the folding plane 11 is to the width of the aerosol generating matrix 2, the higher the heat utilization rate of the heating element 1, and the more fully the aerosol generating matrix 2 releases aerosols.

[0037] In some embodiments, the surface roughness of the aerosol generating matrix 2 is 0.07 mm to 0.10 mm. In the embodiments of this application, the surface of the aerosol generating matrix 2 has a certain roughness, which allows the generated aerosol to pass through even when it is folded and attached to the body of the heating element 1.

[0038] In some embodiments, the bent section of the heating element 1 and / or the bent section of the aerosol generating matrix 2 are provided with through holes 5. In the embodiments of this application, refer to... Figure 4 The bent sections of the heating element 1 and the aerosol generating matrix 2 are provided with through holes 5, which allow airflow to pass through and carry away the generated aerosols. Placing the through holes 5 in the bent sections makes it easier to carry away the aerosols.

[0039] In some embodiments, the sandwich aerosol product further includes a base 4 and pins 3. Pins 3 are respectively provided at both ends of the heating element 1, and the pins 3 are fixed to the base 4 for electrical connection to the heating appliance. (Refer to...) Figure 3 In this embodiment, the heating element 1 has at least two pins 3. The pins 3 and the heating element 1 can be integrally formed or soldered together. The resistance of the pins 3 is greater than the resistance of the heating element 1, which can reduce the heat generated by the pins 3. When the thickness of the pins 3 and the body of the heating element 1 is the same, the width of the pins 3 is greater than or equal to the width of the body.

[0040] In this embodiment, the aerosol generating matrix 2, the heating element 1, and the base 4 are assembled stably, reducing the processing difficulty and cost of the heating element 1. At least two pins 3 are disposed within the base 4, and these pins 3 are used for electrical connection to external circuits. The central axis of the base 4 coincides with that of the heating element 1. The cross-sectional shape of the base 4 matches the outer contour of the cross-section of the combined heating element 1 and the aerosol generating matrix 2. Preferably, the cross-sectional shape of the base 4 is rectangular.

[0041] The base 4 fixes the heating element 1, placing it within the aerosol generating matrix 2 at a specific location. The base 4 is made of polymers, fibers, preferably tobacco materials and tobacco-related materials as stipulated in the "Tobacco Monopoly Management Regulations." If necessary, other materials can be added to allow it to be molded into specific shapes, achieving mechanical features such as holes, bosses, and grooves. The base 4 may have a through hole extending from one end to the other.

[0042] In addition to achieving a certain level of mechanical strength, the material and manufacturing process of base 4 also include providing a certain degree of porosity and hydrophilicity, enabling the adsorption and storage of liquids such as flavorings. Its hydrophilicity requires a surface contact angle of ≤30°C with deionized water. The hydrophilicity of base 4 is used to add necessary liquid components to improve the user experience, such as enhancing taste. The liquids added to base 4 are typically flavorings with a release temperature between 65°C and 280°C, but the higher the temperature, the faster the release. These flavorings include vanillin, maltol, ethyl acetate, porous paper base, cyclodextrin microcapsules, and cross-linked polymer microcapsules.

[0043] The hydrophilicity of the base 4 will absorb added flavorings or other liquids, such as tobacco extracts. The heating element 1 has a large surface area, generating uniform high heat. The temperature difference between points on the aerosol generating matrix 2 is small, and the aerosol generating matrix 2 attached to both sides can be evenly baked. The pin 3 generates less heat, which is conducted to the base 4 to match the slow-release temperature of the aerosol auxiliary material. This makes the slow-release time of the substances added in the base 4 longer than the release time of the first part, thereby achieving a consistent flavor for each puff throughout the entire release cycle of the aerosol product.

[0044] After the base 4 is combined with the heating element 1 and the aerosol generating matrix 2, a packaging body can be placed on the outside of the assembly. The packaging body can support the assembly and fix it as a whole so that it cannot be easily disassembled. The packaging body wraps the aerosol generating matrix 2 and the base 4 along their length with continuous packaging material, and the remaining two ends are sealed with a sealing part. The sealing part is detachable. When the sealing part is not removed, air cannot enter the aerosol generating matrix 2, which can extend its shelf life. When the sealing part is removed, air can enter and carry away the aerosol generated after heating. The sealing part can be detached by adhesive bonding to one end of the aerosol generating matrix 2 and one end of the base 4. The packaging body is preferably made of paper, but plant fibers, fabrics, resin films, plastic films, etc. can also be used.

[0045] 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.
