Description

Technical Field

[0001] The present invention relates to the field of heated tobacco product technology, and in particular to a granular heated tobacco product provided with an induction heating unit and a manufacturing method therefor.

Background Art

[0002] The main advantage of heated tobacco products lies in that they can effectively reduce known harmful smoke components generated by combustion and pyrolysis of conventional cigarettes. Electrically heated tobacco products are a type of new tobacco product that has developed relatively rapidly, and can be classified into resistance heating type, electromagnetic heating type, infrared heating type, microwave heating type and other electrically heated tobacco products based on the type of heating technology adopted. Electromagnetic heating type tobacco products have become the focus of research and development by tobacco manufacturers due to their advantages such as high electric energy conversion efficiency, rapid heating, and enabling non-contact energy transmission. At present, most of the developed electromagnetic heating type tobacco products have a heating element built into a heated smoking device. When suction is performed using such an electromagnetic heating type tobacco product, the heating element of the heated smoking device needs to be inserted into the interior of the aerosol-generating medium of the heated tobacco, and after the suction is completed, the heating element and the heated tobacco need to be separated. Therefore, there are problems that the heating element adheres to the aerosol-generating medium which requires cleaning, and the housing temperature of the heated smoking device is likely to rise excessively.

[0025] The present invention has the following advantages compared with the prior art. 1. The granular heated tobacco product provided with the induction heating unit according to the present invention has the induction heating unit built into the heated tobacco product, and is used in combination with a corresponding electromagnetic heating smoking device. In this way, most of the heat of the induction heating unit built into the heated tobacco product during the suction process can be used for heating the smoke-generating granule unit, which increases heat efficiency, effectively improves the heating efficiency of the heated tobacco product, enables the heated tobacco product to generate sufficient and uniform smoke, and reduces the outward diffusion of heat. Therefore, the casing temperature of the electromagnetic heating smoking device and the heat-induced impurity gas in the smoke of the heated tobacco can be significantly reduced. Moreover, after the suction is completed, it is only necessary to directly pull the heated tobacco product out of the electromagnetic heating smoking device as a whole, no auxiliary take-out device is required, no cleaning of the smoking device is required, and the appearance of the tobacco stick does not change. In addition, both ends of the smoke-generating granule unit are respectively sealed by the blocking cooling unit and the sealing unit, which effectively prevents tobacco granules from falling off during suction.

[0026] 2. The granular heated tobacco product equipped with the induction heating unit according to the present invention has three types of structural designs for the induction heating unit. These three structural designs increase the contact area between the induction heating unit and the smoke-generating granule unit, thereby increasing the heat induction area and enhancing the heating effect of the smoke-generating granule unit. Furthermore, the smoke-generating granules within the smoke-generating granule unit can be uniformly dispersed, ensuring uniform heating within the smoke-generating granule unit, and further promoting the generation of sufficient and uniform smoke in the heated tobacco product. The operation of fitting these structural types of induction heating units into the hollow tobacco stick outer tube is simple.

[0038] This embodiment further provides a method for manufacturing a granular heated tobacco product equipped with the above-mentioned induction heating unit 6, and includes steps 1 to 7.

[0039] (Step 1: Manufacturing of tobacco stick outer tube 1) The tobacco stick outer tube 1 is manufactured by mixing one or at least two of the following: pulp fibers, non-tobacco plant fibers, wood pulp fibers, bamboo pulp fibers, and tobacco materials.

[0040] (Step 2: Manufacturing of the sealing unit 2) A sealing unit 2 is manufactured by mixing at least one or at least two of the following: ceramics, clay, glass, heat-resistant plastic materials, non-induction heating metals and alloys, pulp fibers, tobacco materials, and non-tobacco plant materials. Materials such as ceramics, clay, glass, heat-resistant plastic materials, and non-induction heating metals and alloys can be used to manufacture the sealing unit 2 by a casting process, while materials such as pulp fibers, tobacco materials, and non-tobacco plant materials can be used to manufacture the sealing unit 2 by a screw extrusion process.

The mixed granules of tobacco and plant flavorings can be formed as spherical granules or as granular granules with a circular cross-section by a granulation process.

[0042] (Step 4: Manufacturing of the induction heating unit 6) An induction heating unit 6 is manufactured using an electromagnetic induction heating material, the electromagnetic induction heating material includes ferrite, martensite, stainless steel, neodymium iron boron, and the above alloy materials, and the induction heating unit 6 can be manufactured by selecting one or at least two of the above materials and using a metal casting process or a numerically controlled machine tool.

[0043] (Step 5: Manufacturing of the shut-off cooling unit 5) The blocking cooling unit 5 is manufactured by mixing one or at least two of the following: ceramics, glass, high-polymerization environmentally friendly plastics, activated carbon, starch-based materials, tobacco materials, and herbaceous plant materials.

[0044] (Step 6, Manufacturing of filter unit 3) The filter material is either manufactured alone, or a filter unit 3 having a porous structure is manufactured by mixing the filter material with at least one of the following: burst beads, sustained-release phase change material, fragrance thread, Cosmel pack, or cooling granules.

[0045] (Step 7, forming the tobacco stick) The tobacco stick outer tube 1, sealing unit 2, blocking cooling unit 5, and filter unit 3 are cut to a predetermined length. Then, the sealing unit 2, induction heating unit 6, smoke granule unit 4, blocking cooling unit 5, and filter unit 3 are placed in the tobacco stick outer tube 1 such that the induction heating unit 6 is located inside the smoke granule unit 4, and both ends of the smoke granule unit 4 are sealed by the blocking cooling unit 5 and the sealing unit 2, respectively, to obtain a tobacco product.

[0046] To verify the effectiveness of the granular heated tobacco product equipped with the induction unit according to this embodiment, the applicant used a granular heated tobacco product equipped with the third structural form of the induction heating unit 6 according to this embodiment as a sample, and a granular heated tobacco product without the induction heating unit 6 as a control example, comparing the two. Graphs showing the changes in smoke emission volume and smoke temperature with inhalation time for both products were obtained. Figure 5 shows the graph of the change in smoke emission volume with inhalation time for both products, and Figure 6 shows the graph of the change in smoke temperature with inhalation time for both products. As can be seen from Figures 5 and 6, under equivalent conditions, the granular heated tobacco product equipped with the induction heating unit 6 exhibits a more sufficient smoke emission volume and lower smoke temperature compared to the granular heated tobacco product without the induction heating unit 6. The granular heated tobacco product equipped with the induction heating unit 6 shows a significant advantage in both smoke emission volume and smoke temperature.

[0047] Simultaneously, the applicant used three different structural forms of induction heating units 6 incorporated into the tobacco product according to this embodiment as samples of induction heating units 6, designated as the first, second, and third induction heating unit 6 samples, respectively, and a conventional induction heating unit 6 installed in a heated smoking device as a control example. The applicant compared the two and obtained graphs showing the change in temperature of each with respect to heating time. The graphs showing the change in temperature of the three structural forms of induction heating units 6 and the control example of induction heating units 6 are shown in Figures 7 to 9. As can be seen from Figures 7 to 9, under equivalent conditions, the temperature of the induction heating unit 6 incorporated into the tobacco product according to this embodiment is higher than that of the induction heating unit 6 installed in a heated smoking device, indicating that the induction heating unit 6 incorporated into the tobacco product according to this embodiment has a better heating effect.

[0048] Furthermore, in order to verify the influence of the induction unit of this embodiment on the temperature of the heated tobacco device housing, the applicant used a granular heated tobacco product equipped with the induction heating unit 6 according to this embodiment as a sample and a granular heated tobacco product without the induction heating unit 6 as a control example, and compared the two, obtaining graphs of the change in the temperature of the heated tobacco device housing during inhalation with respect to the inhalation time for each of the two. Three types of granular heated tobacco products equipped with three types of structural forms of induction heating unit 6 were each designated as three samples, and the three types of samples were designated as the first type sample, the second type sample, and the third type sample. The inhalation methods were distinguished into two types: single inhalation and continuous inhalation, and each was compared with the control example, obtaining graphs of the change in the temperature of the heated tobacco device housing during inhalation with respect to the inhalation time for each type of sample and the control example, which are shown in Figures 10 to 15. As can be seen from Figures 10 to 15, under equivalent conditions, the granular heated tobacco product equipped with the induction unit according to this embodiment exhibits higher thermal efficiency because the temperature of the heated smoking device housing is lower during inhalation, compared to a granular heated tobacco product without the induction heating unit 6, thus demonstrating a more effective heat-preventive effect.

[0049] The foregoing are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall all be within the scope of protection of the present invention.
