Description

Technical Field

[0001] This invention relates to the field of tobacco product technology in the tobacco industry, specifically to a porous material for heating non-combustible tobacco products and methods. Background Technology

[0002] New tobacco products mainly refer to cigarette products that differ from those using traditional combustion methods, primarily including heated tobacco products and electronic cigarettes. For example, prior art CN104921296A discloses a composite filter rod for heated tobacco products, comprising the following sequentially connected sections: a solid filter, a first hollow filter or a first cavity, a second hollow filter, and a third hollow filter or a third cavity. It has multiple functions, such as mixing smoke and shortening smoke response time, and also offers advantages such as increasing the amount of smoke in heated tobacco products, reducing smoke temperature, and improving the sensory quality of heated tobacco products. Prior art CN101396173A discloses a method for vortex cooling and aroma preservation of cigarettes and its cigarette structure. Before the cigarette smoke enters the cigarette filter rod, a vortex channel is set up. This vortex channel is connected to the outside air through pores. The cigarette smoke naturally cools within the vortex channel and mixes thoroughly with the external air entering the vortex channel. Then, the cigarette smoke undergoes complete filtration through the filter tip. It has the advantages of reducing the inhalation of cigarette tar while maintaining the ratio of aroma substances and moisture in the smoke, thus preserving the comfortable taste of cigarettes. Existing technology CN105996119A discloses a composite filter rod and its application in heated tobacco products, comprising: a tobacco rod composed of tobacco material wrapped in a first forming paper; a first hollow filter composed of polymer fiber material wrapped in a third forming paper, having a first hollow cavity; and a second hollow filter composed of polymer fiber material wrapped in a fourth forming paper, having a second hollow cavity. The tobacco rod, the first hollow filter, and the second hollow filter are connected and then wrapped in the second forming paper to form the composite filter rod. It is also used to reduce the aldehyde content in heated tobacco product smoke.

[0003] Currently, most heated cigarettes use air as the carrier of smoke. In order to ensure that the tobacco does not burn, the heating temperature is usually low, generally not exceeding 300°C. Compared with traditional cigarettes, the aroma components of tobacco in new heated cigarettes are difficult to be fully released, the amount of smoke is insufficient, and nicotine is mainly concentrated in the central area of ​​the mainstream smoke. Therefore, these cigarettes are less likely to be accepted by traditional smokers. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a heated non-combustible tobacco product and method using porous materials. The end of the tobacco product is filled with aroma-enhancing components through a porous material. By filling the porous material with aroma-enhancing substances and air, during inhalation, the aroma-enhancing substances and air filled with the porous material mix with the smoke generated by heating. The mixed gas migrates through the cigarette and mixes with the air on the sidewalls in the cavity area to form mainstream smoke. Because the density and mass of the aroma-enhancing substances differ from the aerosol composition formed by heating the cigarette, the mixing degree of the mainstream smoke is further intensified, thereby increasing the tobacco aroma and diluting the nicotine content in the smoke during inhalation, reducing the irritation of nicotine, and enhancing the sensory experience.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A porous material for heating non-combustible tobacco products includes a porous material (1), a tobacco segment (2), a cavity (3), sidewall through holes (4), and a functional filter segment (5). The porous material is filled at the leftmost end of the tobacco product, and the porous material area is filled with tobacco aroma substances and air. The tobacco segment is disposed between the porous material and the cavity, and there is a small gap between the porous material and the tobacco segment. The length of the small gap is 0.35-0.5 times the length of the porous material. The functional filter segment is disposed at the right end of the cavity, and multiple sidewall through holes are disposed on the outer peripheral wall of the cavity. The porous material, small gap, tobacco segment, cavity, and functional filter segment are arranged sequentially along the length direction of the tobacco product.

[0006] Furthermore, aroma-enhancing components and air are added to the end of the tobacco product, and the aroma-enhancing substances are adsorbed onto the surface of the porous material.

[0007] Furthermore, the smoke is extracted into the mainstream smoke through the suction pressure difference and mixed with it to form the mainstream smoke. The aroma components, air and fresh smoke generated by the cigarette tobacco segment have different densities and masses. The suction airflow increases the degree of mixing and enhances the tobacco aroma in the mainstream smoke. By diluting the nicotine content in the center of the mainstream smoke, the uniformity of nicotine distribution in the mainstream smoke is improved, thereby improving the sensory quality of heated tobacco products.

[0008] Furthermore, a porous material region is added to the end of the design, and tobacco aroma components are added to this region, increasing the aroma in the mainstream smoke and enhancing the smoking experience. The porous material in the end region stores some air; due to the compression of air caused by inserting and removing the cigarette tobacco, and the fact that the length of the small gaps is 0.4-0.45 times the length of the porous material, the pressure difference between the end and the cavity is further increased, further enhancing the smoke's migration ability and the oxygen content in the mainstream smoke. The aroma substances adsorbed on the surface of the porous material pores and the air stored inside the pores, due to their different density and mass compared to the fresh smoke generated by the cigarette tobacco segment, enhance the mixing degree of the aroma substances, air, and fresh smoke, diluting the nicotine content in the central area of ​​the mainstream smoke, reducing the irritation of smoking, and improving the fullness of the smoke.

[0009] This invention discloses a heated non-combustible tobacco product and method using porous materials. The end of the smoking device is filled with a porous material containing aroma-enhancing components. By filling the device with aroma-enhancing substances and air, during inhalation, the aroma-enhancing substances and air in the porous material mix with the smoke generated by heating. The mixed gas migrates through the cigarette and mixes with the air on the sidewalls in the cavity area to form mainstream smoke. Because the density and mass of the aroma-enhancing substances differ from the aerosol composition formed by heating the cigarette, the mixing degree of the mainstream smoke is further intensified, thereby increasing the tobacco aroma and diluting the nicotine content in the smoke, reducing the irritation of nicotine, and enhancing the sensory experience.

[0012] To make the technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in a clearer and more complete manner below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of the present invention, and are only used to explain the present invention, not to limit the present invention. It should be noted that, for ease of description, only the parts / structures related to the present invention are shown in the accompanying drawings. Other related parts can be referred to with ordinary design. In the absence of conflict, the embodiments and technical features in the embodiments of the present invention can be combined with each other to obtain new embodiments.

[0013] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. Furthermore, unless otherwise defined, the technical or scientific terms used in the description of this invention should have the ordinary meaning understood by those skilled in the art.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] like Figure 1 As shown, a heat-not-burn tobacco product made of porous material includes a porous material 1, a tobacco segment 2, a cavity 3, sidewall through holes 4, and a functional filter segment 5. The porous material 1 is filled at the leftmost end of the tobacco product, and the porous material area is filled with tobacco aroma substances and air. The tobacco segment 2 is disposed between the porous material 1 and the cavity 3, and there is a small gap between the porous material 1 and the tobacco segment 2. The length of the small gap is 0.35-0.5 times the length of the porous material 1. The functional filter segment 5 is disposed at the right end of the cavity 3. Multiple sidewall through holes 4 are disposed on the outer peripheral wall of the cavity 3. The porous material 1, the small gap, the tobacco segment 2, the cavity 3, and the functional filter segment 5 are arranged sequentially along the length direction of the tobacco product.

[0016] This porous material in heated tobacco products features a porous material region at the end, where tobacco aroma components are added to enhance the flavor of the mainstream smoke and improve the smoking experience. The porous material in the end region stores some air; the insertion and removal of the cigarette tobacco compresses the air, and the length of these small gaps is 0.35-0.5 times (preferably 0.4-0.45 times) of the porous material's length, further increasing the pressure difference between the end and the cavity. This further enhances the smoke's migration ability and the oxygen content in the mainstream smoke.

[0017] The aroma compounds adsorbed on the porous surface of the material and the air stored inside the pores, due to their different density and mass from the fresh smoke generated by the tobacco segments of cigarettes, enhance the mixing degree of aroma compounds, air and fresh smoke, dilute the nicotine content in the central area of ​​the mainstream smoke, reduce the irritation of smoking, and improve the fullness of smoking.

[0018] This invention discloses a heated tobacco product and method using porous materials. By adding a porous material region to the end region of the heated tobacco product, this region can be filled with tobacco aroma compounds and air. The aroma compounds are adsorbed onto the surface of the porous material, while the air is primarily stored in the pores of the porous material through compression during the insertion and removal of the cigarette. The aroma compounds and air in the end porous material region are extracted into the mainstream smoke by the pressure difference created during the inhalation process, utilizing the principle of gas migration. The air in the end porous material region mixes with the fresh smoke generated by the cigarette tobacco segment, forming the mainstream smoke. Because the aroma compounds, air, and fresh smoke generated by the cigarette tobacco segment have different physical properties (density, mass), the inhalation airflow increases the degree of mixing, enhancing the tobacco aroma in the mainstream smoke, further diluting the nicotine content in the center of the mainstream smoke, and improving the uniformity of nicotine distribution in the mainstream smoke, thereby improving the sensory quality of the heated tobacco product.

[0019] The above embodiments are illustrative of the present invention and not intended to limit the invention. It is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
