Description

[Technical field]

[0001] The present invention belongs to the technical field of heat-not-burn cigarettes, and more specifically, to a cigarette cartridge adapted for smoking with an infrared heating device. [Background technology]

[0002] Heat-not-burn cigarette cartridges are cigarettes that are heated by electronic heating equipment to produce smoke for consumers to experience. This type of cigarette does not produce open flames and ash during the smoking process, which is environmentally friendly, allowing consumers to feel the fragrance and smoke when smoking cigarettes through electronic heating equipment. At the same time, it reduces the harmful substances produced by high-temperature pyrolysis during the combustion of conventional cigarettes, providing an effective way for consumers to smoke healthily. The heat source of the electronic heating equipment is resistance heating and electromagnetic heating, and the heating method is central heating and circumferential heating. It is a heat conduction heating method and a contact heating method. Infrared heating is a relatively common heating technology. Infrared radiation heating technology mainly studies the interaction mechanism between infrared radiation and material structure. The infrared heating source emits infrared rays, which are absorbed by the heated material to produce a thermal effect. When the frequency of infrared rays irradiated on an object matches the vibration frequency of the molecules of the material that composes the object, the molecules resonate and absorb the energy of the infrared rays, produce strong vibrations and rotations, and the vibrations and rotations increase the temperature of the object, achieving the purpose of heating. It is a heating method of thermal radiation and belongs to non-contact heating.

[0003] The infrared heater uses infrared rays to heat the smoking matrix through the wrapping layer of the smoking matrix, providing heat energy to the smoking matrix of the cigarette in the form of thermal radiation to generate smoke. This is essentially different from the traditional resistance circumferential heating heat transfer heating method. Traditional circumferential heating mainly heats the smoking matrix from the outside to the inside, first heating the heating tube and then heating the wrapping layer in turn, and then transferring to the smoking matrix. The wrapping layer is constantly heated, which has a great impact on the smoking taste. Infrared heating is non-contact heating, which directly heats the smoking matrix without heating the wrapping layer.

[0004] At present, it is difficult to achieve the expected heating effect by directly applying the existing heated cigarettes to such infrared heating smoking utensils. It is difficult for infrared radiation to directly act on the smoking substrate, the heat transfer speed is very slow, and the smoke volume and the smoking taste are not as good as those of the resistance heating smoking utensils. CN 112369669 discloses a heating-not-burning cigarette suitable for an infrared heating device. The wrapping layer used has an infrared transmittance of 55%. The infrared transmittance is increased by using oil-proof paper, but the overall transmittance is relatively low. There is still a partial heating effect on the wrapping layer, which has a certain impact on the smoking taste, and the intensity of infrared radiation received by the smoking substrate is reduced, resulting in an overall decrease in the smoking experience. CN 217242657 discloses a cigarette adapted for infrared heating, but this cigarette is adapted for infrared heating smoking utensils with center heating. Although the wrapping layer is not infrared heated, the center heating pollutes the smoking utensils after the smoking is completed, affecting the consumer's experience.

[0005] Therefore, in view of the many technical defects in the prior art, the inventors analyzed and summarized the prior art, and conducted a large number of experiments and analyses, and finally completed the present invention. [Summary of the invention]

[0034] According to another preferred embodiment of the present invention, the adapted infrared heating device is a heating device selected from mid-infrared, far-infrared or mid-far-infrared.

[0035] The present invention will be described in more detail below.

[0036] The present invention relates to a cigarette cartridge adapted for smoking with an infrared heating device. The specific structure is shown in the attached Figure 1-2 .

[0037] The cigarette cartridge adapted for smoking with infrared heating equipment is composed of a plug section 1, a smoke-generating section 2 and a filter section 3 which are sequentially filled in a high infrared transmittance tube 4; the thickness of the high infrared transmittance tube 4 is 0.01 to 2.00 mm, its outer diameter is 3 to 10 mm, and its infrared radiation transmittance in the infrared wavelength range of 4 to 20 μm is above 75%.

[0038] The principle of infrared heating is that the infrared rays emitted by the infrared heating source are absorbed by the heated material to produce a thermal effect. When the frequency of the infrared rays irradiated on the object matches the vibration frequency of the molecules of the material that compose the object, the molecules absorb the energy of the infrared rays and resonate, resulting in strong vibration and rotation. The vibration and rotation increase the temperature of the object, achieving the purpose of heating.

[0039] In the heat-not-burn cigarette cartridge, the infrared radiation heating technology heats the smoking substrate that receives infrared radiation after the infrared radiation emitted by the infrared radiation end passes through the wrapping layer of the smoking substrate, thereby generating smoke and aroma. Therefore, the cigarette cartridge adapted for smoking with infrared heating equipment has relatively high requirements for the smoking substrate wrapping layer, which should be a material with high infrared transmittance.

[0040] The thickness of the high infrared transmittance tube 4 of the present invention is 0.01-2.00mm. When infrared rays pass through an object, they will be reflected, scattered, and absorbed by the material of the object. The thickness will reduce the transmittance of infrared rays to a certain extent. The thicker the thickness, the lower the infrared transmittance. If the thickness is less than 0.01mm, the material used to prepare the high infrared transmittance tube 4 is easily damaged during the processing, affecting the appearance quality of the cigarette bomb; if its thickness is greater than 2.00mm, it will cause the production cost of the high infrared transmittance tube to increase, and the infrared transmittance will be significantly reduced. Therefore, it is reasonable for the thickness of the high infrared transmittance tube to be 0.01-2.00mm.

[0041] According to the present invention, the thickness of the high infrared transmittance tube 4 in the part corresponding to the plug section 1 is 0.01-2.00mm; the thickness in the part corresponding to the smoking section 2 is 0.01-1.00mm, and the thickness in the part corresponding to the filtering section 3 is 0.01-2.00mm. In the three parts, when the thickness of the high infrared transmittance tube wall is 0.01mm, the inner wall of the tube is kept uniform. If the thickness of the high infrared transmittance tube wall is less than 0.01mm, the tube is easily damaged during processing, and the appearance quality of the cigarette bomb is also affected. The thickness of the smoking section 2 is 0.01-1.00mm, which can ensure that infrared radiation acts on the smoking matrix with high transmittance, thereby ensuring that users have a good experience effect when using the cigarette bomb of the present invention. If the thickness of the plug section 1 and the filtering section 3 is greater than 2.00mm, the amount of pipe material used to manufacture the high infrared transmittance tube 4 will increase significantly, and its production cost will also increase accordingly, but people's experience effect of using the cigarette bomb of the present invention will not be significantly improved.

[0042] In the present invention, the outer diameter of the high infrared transmittance tube 4 is 3 to 10 mm. If the outer diameter of the high infrared transmittance tube 4 is less than 3 mm, the diameter of the cigarette cartridge is relatively small, the inhalation resistance is relatively large during inhalation, and the number of inhalation puffs is relatively small, which affects the inhalation experience; if the outer diameter of the high infrared transmittance tube 4 is greater than 10 mm, the diameter of the cigarette cartridge is relatively large, the energy consumption of the heater is relatively large, and the number of inhalations of the heated smoking device is reduced; therefore, the outer diameter of the high infrared transmittance tube 4 is suitable to be 3 to 10 mm, preferably 4 to 8 mm.

[0043] According to Wien's displacement law, the wavelength range corresponding to the temperature of infrared radiation below 500°C is 4 to 20 μm. According to GB / T 36403-2018 "Infrared Transmittance Test Method for Infrared Optical Glass - Fourier Transformation Method", the infrared radiation transmittance of the high infrared transmittance tube 4 of the present invention is above 75%.

[0044] In the present invention, the infrared transmittance of the high infrared transmittance tube 4 is high, and the heat emitted by the infrared heating device is mainly absorbed by the smoke-generating substrate, which will cause the smoke-generating substrate to heat up rapidly. Due to the heat conduction of the material, the heat of the smoke-generating substrate will be conducted to the wrapping layer, causing the wrapping layer to heat up. If the temperature of the wrapping layer rises to above 300°C, the tube may melt or thermally collapse, contaminating the smoking utensils and affecting the smoking experience. Therefore, the heat-resistant temperature of the high infrared transmittance tube 4 should be above 300°C.

[0045] According to the present invention, the high infrared transmittance tube 4 is formed by a material selected from polycarbonate, polymethyl methacrylate, polystyrene, magnesium fluoride glass or silica gel using a molding device or an extrusion injection molding device, and it has a high barrier to liquid leakage. Using the above standard method for detection, the infrared transmittance of these materials exceeds 80%, they all have good infrared transmittance, and also have excellent chemical properties. They have excellent anti-leakage and barrier effects on the smoke-generating agent and flavoring material components of the smoke-generating section 2, ensuring that the overall appearance of the smoke bomb is neat before and after smoking, and improving the consumer experience effect. These materials used in the present invention are all products currently sold on the market, such as polycarbonate sold by Shandong Fuhan New Materials Technology Co., Ltd. under the trade name PC endurance board, polymethyl methacrylate sold by Hubei Xinjiecheng Chemical Technology Co., Ltd. under the trade name PMMA, and magnesium fluoride glass sold by Jinan Jingzhong Optoelectronics Technology Co., Ltd. under the trade name magnesium fluoride film. The molding equipment used in the present invention is, for example, a product sold by Xingtai Jieyu Machinery Manufacturing Co., Ltd. under the trade name of a silicone molding machine; the extrusion injection molding equipment used in the present invention is, for example, a product sold by Shenzhen Jintong Plastic Machinery Co., Ltd. under the trade name of an injection molding machine;

[0046] The high infrared transmittance tube 4 used in the present invention can be formed by conventional one-piece molding, and then the plug section 1, the smoke-generating section 2 and the filter section 3 structural units are filled into the tube in sequence.

[0047] In the present invention, the plugging section 1 is made of a material selected from acetate fiber, propionate fiber, polylactic acid fiber or cellulose paper. The acetate fiber used in the present invention is the tow used in ordinary cigarette filter rods. Of course, the present invention can also use propionate fiber, polyester fiber and polylactic acid fiber; the cellulose paper used in the present invention is, for example, paper fibers such as aluminum foil paper, absorbent paper, oil-proof paper and cotton paper, which are all products currently sold on the market. In the present invention, the material for making the plugging section 1 can be the same as the material of the smoking section 2 or the filtering section 3.

[0048] The air permeability of the plug section 1 of the present invention is greater than or equal to 0 (m 3 / s·m 2 ·Pa). Air permeability is equal to 0 (m 3 / s·m 2 ·Pa), which means that the material constituting the plug section 1 is very dense, and air can only enter the cigarette cartridge from the side wall of the cigarette. The air permeability of the plug section 1 is greater than 0 (m 3 / s·m 2 ·Pa), which means that the material constituting the plug section 1 is not densely filled, and air can enter the cigarette cartridge through the plug section 1. In the present invention, the air permeability of the plug section is measured according to the GB / T 5453 standard using the method of "Determination of Air Permeability of Textile Fabrics".

[0049] According to the present invention, the smoke generating section 2 and the filter section 3 are connected in the same longitudinal axis. A permeable barrier layer 5 or a buckle 7 is arranged between the smoke generating section 2 and the filter section 3. For details, see the attached Figure 1-2 ;

[0050] The main function of the air-permeable barrier layer 5 is to separate the smoke-generating substrate and prevent the smoke-generating substrate of the smoke-generating section 2 from shifting when heated, thereby affecting people's smoking experience. In the present invention, the air permeability of the air-permeable barrier layer 5 is greater than 0m 3 / (s·m 2 ·Pa), which means that the air permeable barrier layer 5 has air holes and many gaps, which facilitates smoke to pass through the air permeable barrier layer 5 and enter the filter section 3 for consumers to experience. The diameter of these gaps is usually less than 0.5 mm to prevent the smoke-generating substrate of the smoke-generating section 2 from entering the filter section 3. In the present invention, the air permeability of the barrier layer is measured according to the method specified in GB / T5453 standard "Determination of air permeability of textile fabrics".

[0051] In the present invention, the thickness of the air-permeable barrier layer 5 is 0.1 to 10.0 mm. If the thickness of the air-permeable barrier layer 5 is less than 0.1 mm, it will be damaged during packing, and the smoke-generating matrix will be easily displaced. If the air-permeable barrier layer 5 is greater than 10.0 mm, the smoke will condense during the smoking process, reducing the release of aroma and smoke, affecting the smoking experience.

[0052] In the present invention, the smoking section 2 and the filtering section 3 are connected by an air-permeable barrier layer 5, and a space is formed between the air-permeable barrier layer 5 and one end of the filtering section 3. The size of this space can be adjusted accordingly when manufacturing the cigarette cartridge according to actual needs. For details, see the attached Figure 1 One or more aroma substances selected from flavoring particles, popping beads, gel or flavor powder are filled in the space to increase the aroma release when people smoke and satisfy the enjoyment of smoking the cigarette cartridge. See attached Figure 1 The cavity bursting beads 6 include, for example, the flavored granules sold by Yunnan Bagu Biotechnology Co., Ltd. under the trade name Blueberry Mint Corn Granules, the bursting beads sold by Yunnan Bagu Biotechnology Co., Ltd. under the trade name Hami Melon Mint Capsules, the gel sold by Yunnan Bagu Biotechnology Co., Ltd. under the trade name Tangerine Peel Gel Granules, and the flavored powder sold by Yunnan Bagu Biotechnology Co., Ltd. under the trade name Watermelon Powder Flavor.

[0053] Of course, this space can also be filled with no substance.

[0054] According to the present invention, the air-permeable barrier layer 5 is made of a material selected from polycarbonate, polymethyl methacrylate, polystyrene, magnesium fluoride glass or silica gel, which have been described above and will not be described again here.

[0055] In the present invention, the buckle 7 is, for example, an existing thread structure, a mortise and tenon structure or a slot structure, for example, the thread structure specifically refers to document CN202221830005.3, the invention name "A sleeve thread locking structure" discloses a thread locking structure; the mortise and tenon structure specifically refers to document CN 202220741699.7, the invention name "A special mortise and tenon fixing part" discloses a mortise and tenon locking structure; the slot structure specifically refers to document CN202011255780.6, the invention name "A quick slot locking device" discloses a slot locking structure; the main function of the buckle 7 is to separate the smoking matrix and prevent the smoking matrix of the smoking section 2 from being displaced during heating, affecting people's smoking experience.

[0056] According to the present invention, the material filled in the smoking section 2 is tobacco raw material, non-tobacco raw material or a mixture thereof. Wherein, the tobacco raw material is one or more tobacco raw materials selected from burley tobacco, flue-cured tobacco, oriental tobacco, sun-cured tobacco or air-cured tobacco, which are all products currently sold on the market. The non-tobacco raw material is one or more non-tobacco raw materials selected from cotton fiber, mint, coffee, betel nut or tea, such as coffee sold under the trade name coffee beans by Yunnan Coffee Factory Co., Ltd. and betel nut sold under the trade name green fruit by Hunan Taste King Group Co., Ltd.

[0057] The material of the smoking section 2 is a filamentary, flake-like, powdery, granular or paste-like material, for example, a filamentary material with a diameter of 0.1-1.0 mm and a length of 0.5-20.0 mm, a flake-like material with a thickness of 0.01-2.0 mm and a length of 0.5-20.0 mm, a powdery material with a particle size of 10-60 meshes, a granular material with a particle diameter of 0.2-2.0 mm, and a semi-solid paste-like material.

[0058] In addition to tobacco and non-tobacco materials, the materials filled in the smoking section 2 can also be glycerin, propylene glycol smoke agent, nicotine or nicotine salt physiological strength agent, carboxymethyl cellulose, guar gum or xanthan gum adhesive and other materials. These materials can be added in the form of particles. For details, see the attached Figure 2 The filter segment particles 8 in the invention. The preparation process of the smoking segment 2 can be found in the following documents: CN 201911283915.7, the invention name "A method for preparing a heat-not-burn cigarette sheet" discloses a method for preparing a heat-not-burn sheet, CN 202010773523.5, the invention name "A suction particle for a heat-not-burn cigarette and a preparation method thereof" discloses a method for preparing a heat-not-burn particle, CN 202011508046.6, the invention name "A paste-type binary structure heat-not-burn product" discloses a method for preparing a heat-not-burn paste.

[0059] According to the present invention, an infrared absorbing material with an infrared absorption rate of more than 90% in the infrared wavelength range of 4 to 20 μm is added to the material. The infrared absorption rate of the infrared absorbing material is detected according to the standard method GB / T 36403-2018 "Infrared Optical Glass Infrared Transmittance Test Method Fourier Transformation". The infrared absorbing material is evenly added to the smoking matrix during the preparation of the smoking material. Its main function is to increase the infrared radiation absorption efficiency of the smoking matrix, so that it can be better and more evenly heated, achieve stable smoke output, and obtain a satisfactory aroma. The absorption rate of the infrared absorbing material is detected by the method described above. The addition amount of the infrared absorbing material is 1 to 20% based on the weight of the material. If the addition amount of the infrared absorbing material is less than 1%, the smoking matrix absorbs less infrared, affecting the release of aroma and smoke; if the addition amount of the infrared absorbing material is higher than 20%, the temperature of the smoking matrix is ​​higher, and a burnt smell appears during inhalation; therefore, it is reasonable to add 1 to 20% of the infrared absorbing material, preferably 5 to 16%, and more preferably 8 to 14%;

[0060] The infrared absorbing material used in the present invention is one or more infrared absorbing materials selected from iron oxide, copper oxide, graphene, carbon black, infrared fiber or infrared powder, which are all products currently sold on the market, such as graphene sold by Qingdao Mingrun Chenyue Graphite Co., Ltd. under the trade name of graphene oxide, carbon black sold by Nanjing Xinhuayuan Chemical Co., Ltd. under the trade name of ultrafine carbon black, infrared fiber sold by Hefei Xinneng Phase Change New Material Technology Co., Ltd. under the trade name of far-infrared fiber, and infrared powder sold by Shijiazhuang Xuang Mineral Products Processing Co., Ltd. under the trade name of far-infrared powder.

[0061] In the present invention, the filter segment 3 is made of a material selected from acetate fiber, propionate fiber, polylactic acid fiber or cellulose paper. The acetate fiber used in the present invention is the tow used in ordinary cigarette filter rods. Of course, the present invention can also use other fibers such as polyester fiber; the cellulose paper used in the present invention is, for example, paper fibers such as aluminum foil paper, absorbent paper, oil-proof paper and cotton paper. These materials used in the present invention are products currently sold on the market, such as polylactic acid fiber sold by Jiangmen Danpule Rubber & Plastic Co., Ltd. under the trade name of polylactic acid tow, and cellulose paper sold by Anhui Shenchuang Environmental Protection Technology Co., Ltd. under the trade name of cellulose filter paper.

[0062] The filter section 3 of the present invention is a flavoring filter stick, a bead filter stick or a particle filter stick, or can be a blank filter stick, which plays the role of filtering and flavoring. These filter sticks are all products currently sold on the market.

[0063] The flavored filter rod is one or more flavored filter rods selected from mint, apple, cantaloupe, tangerine peel or coffee; the popping bead filter rod is one or more popping bead filter rods selected from mint, watermelon, rose, blueberry or citrus; the particle filter rod is one or more particle filter rods selected from mint, tea, cellulose, starch or activated carbon. The flavors, popping beads and particles used in these filter rods are all products produced and sold by Yunnan Bagu Biotechnology Co., Ltd.

[0064] The length ratio of the plug section 1, the smoking section 2 and the filter section 3 of the cigarette cartridge of the present invention is 1:1.5-4.0:1-5; the diameter-to-length ratio of the cigarette cartridge is 1:4-14. When the length ratio of the plug section 1 to the smoking section 2 is within the range, if the ratio of the filter section 3 is less than 1, the filtering effect is poor and there are more oral residues; if the ratio of the filter section 3 is greater than 5, the filter section 3 excessively adsorbs the smoke, causing the aroma and smoke to drop significantly, affecting the smoking experience; therefore, the ratio of the filter section 3 is 1-5, which is appropriate, preferably 1.6-4.5. When the length ratio of the plug section 1 to the filter section 3 is within the range, if the ratio of the smoking section 2 is less than 1.5, it will cause insufficient smoke and aroma; if the ratio of the smoking section 2 is greater than 4.0, it will increase the energy consumption of heating the smoking device and reduce the efficiency of the smoking device. Therefore, the ratio of the smoking section 2 is 1.5-4.0, which is appropriate, preferably 2.0-3.6. In the present invention, if the ratio of the diameter to the length of the cigarette cartridge is greater than 1:4, the smoke temperature will be high during the smoking process, affecting the smoking experience; if the ratio of the diameter to the length of the cigarette cartridge is less than 1:14, the cigarette cartridge is too long, and the smoke is condensed by the condensate during the smoking process, causing the attenuation of the aroma and smoke.

[0065] In the present invention, the adapted infrared heating device is a heating device selected from mid-infrared, far-infrared or mid-far-infrared. For example, the mid-infrared heating device is a product sold by Shenzhen Heyuan Technology Co., Ltd. under the trade name Sixhill.

[0066] The present invention selects the original flavor HEETs produced by Philip Morris International as the control cartridge, and uses the IQOS3.0 central heating device and the infrared heating smoking device for puffing evaluation. The smoke volume, smoke temperature, and weight change of the smoking section 2 before and after puffing are compared, and the infrared transmittance of the high infrared transmittance tube 4 and the infrared absorption rate of the infrared absorption material in the smoking matrix are also tested. For specific test results, please refer to the specific implementation method section.

[0067] The evaluation method is described in detail below.

[0068] The original flavor HEETs produced by Philip Morris International were selected and evaluated by smoking with a central heating smoking device as the cartridge sample 1, and the above-mentioned cartridges were selected and evaluated by smoking with the infrared heating smoking device used in Example 1 of the present application as the cartridge sample 2. According to GB / T 36403-2018 "Infrared Transmittance Test Method for Infrared Optical Glass - Fourier Transformation", the infrared transmittance of the high infrared transmittance tube of the smoking section of the present invention and the infrared absorptivity of the infrared absorption material in the smoking matrix were measured; according to Q / CXSW02-200801 "Heat-not-burn Product Smoke Concentration Product Enterprise Standard" of Yunnan Chunxu Biotechnology Co., Ltd., the smoke concentration was measured, and a K-type thermocouple temperature detector was used to measure the smoke temperature of the cartridge during the measurement process; the weight of the smoking section 2 before and after smoking was weighed to compare the changes in evaporation.

[0069] [Beneficial Effects]

[0070] The beneficial effects of the present invention are as follows: the high infrared transmittance tube 4 of the present invention adapted to the infrared heating device for smoking a tobacco cartridge plays the role of a fixed structural member, and its infrared radiation transmittance is above 75%. The tube absorbs little infrared radiation and will not be heated itself, thereby reducing the temperature of the lip end; the smoking section 2 is equipped with a material capable of receiving infrared radiation, thereby improving the utilization rate of infrared radiation, and its aroma and smoke volume are also significantly improved, thereby greatly improving the heating efficiency and uniformity of the infrared heating device; the tobacco cartridge has a plug section 1 at the tobacco end, and the smoking device is clean after smoking, thereby improving the smoking taste and consumer experience; no rolling equipment is used in the production process, the process is simple, and it is easy to realize industrial production.
