[0062] Compared with the prior art, the product made by the method for preparing the heat-not-burn smoke-generating body of the present invention has at least the following advantages:

[0063] 1. Through microwave or high-frequency heating, the strong penetration ability of microwave or high frequency on materials can be used to heat the inside and outside of the smoking paste at the same time. The heating time is short and the effect of uniform heating can be achieved without any heat conduction process. Under vacuum heating, the smoking paste is aged to eliminate the peculiar smell of the smoking paste and make its taste soft. In this method, the smoking paste is baked together with the tube body to form a smoking body with a loose pore structure, suitable suction resistance, and suitable for heating tools to be easily inserted into the smoking body, thereby enhancing the user experience. In addition, microwave or high-frequency heating has a good sterilization effect.

[0064] 2. The use of microwave or high-frequency heating equipment occupies a small area and is simple to operate. It not only reduces the overall preparation cost, but also avoids high environmental temperatures and has the advantages of being pollution-free, energy-saving, and the products are not easy to deteriorate or moldy, which is conducive to long-term storage.

[0065] 3. Obtain good smoking resistance. The suction resistance of the heat-not-burn non-smoking or tobacco product is between 0.75-1.5Kpa, which is basically the same as the suction resistance of traditional lit cigarettes, thereby obtaining a good suction effect.

[0066] 4. The heat-not-burn non-smoke or tobacco product is smoked by heating at 200-300°C. When heated at 200-300°C, the herbal raw materials, Chinese herbal medicine or tobacco raw materials will not decompose and are beneficial to physical and mental health. No harmful substances such as tar will be generated during the heating process.

[0067] 5. Since the water content inside the smoke body is low, 5-10%, the aerosol temperature generated by the heater is low and will not burn the consumer's mouth. At the same time, the liquid flavor in the capsule can supplement the aerosol aroma generated by the smoke body to form a pleasant aerosol.

[0068] 6. The heated or otherwise burned smoke body of the present invention is provided with an anti-penetration label paper, which can prevent the smoke body from absorbing moisture in the air and becoming damp, making the overall appearance beautiful and preventing bacteria or mold from growing on the surface of the smoke body due to dampness of the smoke body.

Figure 2 The present invention is a process flow chart of the method for preparing the heat-not-burn smoke-generating tube. Figure 3 for Figure 2 A semi-finished product of a heat-not-burn smoke-generating body obtained by the preparation method of the present invention. A preparation method of a heat-not-burn smoke-generating body according to an embodiment of the present invention mainly comprises the following steps:

[0082] Step S10, first, providing a hollow tube 10, a smoke-generating raw material, a smoke-generating auxiliary agent and water;

[0083] Step S20, mixing the smoke-generating raw material, the smoke-generating auxiliary agent and water into a paste 11;

[0085] Step S40: extracting the ejector pin 20;

[0086] Step S50: heating the paste 11 by a microwave heating device or a high-frequency heating device to make it heat up and expand, thereby obtaining a semi-finished smoke-generating body;

[0087] Step S60: drying the semi-finished smoke body so that the paste 11 forms a loose pore structure with a porosity of 40-75% in the hollow tube body, and the paste 11 is adhered to the inner wall of the hollow tube body 10 by puffing and combined with the hollow tube body 10 as a whole; and

[0088] Step S70: Finally, a filter tip 12 is disposed at the other end of the hollow tube 10 to produce a heated and non-burning smoke-generating body.

[0089] The specific embodiments of the method for preparing the heat-not-burn smoke-generating body of the present invention and the prepared heat-not-burn smoke-generating body are described in the following specification.

[0090] like Figures 1 to 3 As shown, in step S10, the hollow tube 10 of the present invention can be a hard paper tube, an aluminum foil tube, a tin foil tube, or a high temperature resistant plastic tube or a high temperature resistant silicone tube, which provides the hardness required by the embodiment of the present invention. Figure 1 As shown, this embodiment takes a hard paper tube as an example, which can be purchased directly from a paper tube factory. The hard paper tube raw material is first cut into a hollow tube body 10 of a predetermined length, the length of the hollow tube body 10 is 30-60 mm, preferably 45 mm, and the wall thickness of the hollow tube body 10 is 0.2-0.5 mm, preferably 0.35-0.45 mm. Then, a thimble 20 of a predetermined length is inserted, such as a stainless steel thimble 20 of a length of 30 mm, and a cavity 13 of 10-30 mm in length is formed in the hollow tube body 10, preferably a cavity 13 of 12-18 mm in length. Figure 1 As shown, the ejector pin 20 is inserted when the hollow tube body 10 is prepared. In other embodiments, after the smoke-generating raw materials, smoke-generating aids and water are mixed into the paste 11 and injected into the hollow tube body 10, the ejector pin 20 is inserted into the hollow tube body 10 to squeeze out the excess paste 11 from the tube body 20, and at the same time, the paste 11 at the end of the tube mouth of the hollow tube body 10 is scraped flat, and then the ejector pin 20 is pulled out.

[0091] Preferably, the smoking raw material is crushed into powder in advance, and the powder particle size is preferably 40-200 mesh. Preferably, the powder particle size is 100 mesh. The paste 11 is prepared by mixing the powder of the smoking raw material with a smoking aid, a tobacco flavor and water in a predetermined proportion. In other embodiments, a small proportion of an adhesive and a swelling agent may also be added. Preferably, the smoking raw material is one or more herbal raw materials, Chinese medicinal materials, herbal raw material extracts, tobacco raw materials or tobacco raw material extracts, or any combination selected from herbal raw materials, Chinese medicinal materials, herbal raw material extracts, tobacco raw materials and tobacco raw material extracts.

[0092] The herbal raw materials and herbal raw material extracts are selected from one or more combinations of tea, lotus leaves, mint, licorice, cloves, gynostemma pentaphyllum, ginkgo leaves, guava, wolfberry, mulberry leaves, perilla, jasmine, buckwheat tea, dandelion tea, houttuynia, dried lemons, apples, bananas, dried oranges, pineapples, mangoes, cantaloupes, passion fruits, chrysanthemums, star anise, osmanthus, mulberry leaves, bay leaves, perilla, yellow mandarin oranges, angelica dahurica, tsaoko, tangerine peel, lavender, hawthorn, roses, jasmine, honeysuckle, buckwheat tea, chestnuts, roselle, lily, angelica sinensis, nard, chicken bone grass, costus root, sandalwood, agarwood, a cup, coffee, blueberry, strawberry, hazelnut, marian, lemongrass, queensland fruit, walnuts, almonds, sumac, Brazil nuts, cocoa beans, nutmeg, betel nuts, wood paddles, and plant fibers.

[0093] The Chinese herbal medicine is selected from one or more combinations of raw rehmannia, cooked rehmannia, angelica, cassia seed, dandelion, apocynum venetum, jujube, wolfberry, Fritillaria cirrhosa, Panax notoginseng, Sterculia lychnophora, borneol, menthol, saffron, Poria, Pueraria root, Dalbergia odorifera, Tonka bombycis, Perilla leaf, bupleurum, isatis root, astragalus, selfheal, ginseng, white peony root, Gastrodia elata, Schisandra chinensis, chrysanthemum, and plantain.

[0094] The tobacco raw materials are tobacco leaves and tobacco stems.

[0095] The tobacco raw material extract is selected from one or more combinations of Zimbabwe tobacco extract, burley tobacco extract, Greek tobacco extract, Yunyan tobacco extract, American tobacco extract, Virginia tobacco extract, sun-cured red tobacco extract, tamarind extract, oriental tobacco extract, nicotine, and nicotine salt.

[0096] The smoke-generating aid is selected from one or more combinations of propylene glycol, glycerol, triethylene glycol diacetate, triacetin, triethyl citrate, isopropyl myristate, methyl stearate, and monocaprylin. Preferably, it is selected from one or a combination of propylene glycol and glycerol.

[0097] The tobacco flavor is selected from one or more combinations of peppermint oil, menthol, rose oil, vanilla extract, chocolate flavor, cocoa extract, cinnamic acid ester, star anise oil, alpha-octalactone, white lemon oil, agarwood oil, ethyl maltol, MCP, 2. acetyl pyrazine, 2.3.3-trimethylpyrazine, and cinnamon leaf oil.

[0098] The binder is one or more combinations selected from gelatin, xanthan gum, corn starch, agar powder, pectin, konjac flour, carrageenan, and microcrystalline cellulose.

[0099] The bulking agent is selected from one or more combinations of carboxymethyl cellulose sodium salt, carboxyethyl cellulose sodium salt and microcrystalline cellulose.

[0100] In a preferred embodiment, the paste contains 30-80 parts by weight of smoking raw materials, 5-50 parts by weight of smoking aids, 3-10 parts by weight of tobacco flavorings, 0.01-5 parts by weight of adhesives, 0.01-1 parts by weight of swelling agents, and 10-60 parts by weight of water. Since the swelling agent has a swelling function, it can be combined with water to expand when the paste is mixed, thereby increasing the volume of the paste and reducing the hardness of the paste. Since the present invention uses a microwave heating device or a high-frequency heating device as a heating device, the water content will be more than the water content used in the prior art heat-not-burning smoke-generating body, and the preferred water content is 35-60 parts by weight.

[0101] In step S20, since the present embodiment selects more than 35 parts by weight of water, on the one hand, the paste 11 prepared from the above raw materials can have good fluidity. The water content in this range can make the components form a whole like mud, easy to agglomerate, and relatively tightly combined. After the subsequent drying step, the water will evaporate to form fine pores. If there is too little water, it will not be easy to squeeze into a long strip of paste, and too much water is not conducive to the solidification of the paste 11. On the other hand, in the subsequent microwave or high-frequency puffing fermentation process, the water is evaporated during low-temperature baking to obtain a smoke body with a suitable porosity. In addition, in the blending process of the mixed paste 11, it can be stirred appropriately for better results.

[0102] In step S30, Figure 1 As shown, the hollow tube body 10 has two opposite ends. Before extrusion, the ejector pin 20 is inserted from one end of the hollow tube body 10 and the ejector pin 20 is formed between the end face of the ejector pin 20 in the hollow tube body 10 and the other end of the hollow tube body 10. Preferably, the length of the cavity is 12-18 mm. The paste 11 has a certain length in the hollow tube body 10 to be better expanded and fermented. If it is less than 12 mm, the fermentation effect is not good. If it is longer than 18 mm, the drying time required for the paste 11 is long, which affects the economic benefits and the suction resistance during use. The more optimal paste length is 12.00-15 mm, which can obtain the best suction resistance.

[0103] Furthermore, the outer diameter of the ejector pin 20 is smaller than the inner diameter of the hollow tube body 10, and the length of the ejector pin 20 in the hollow tube body 10 is smaller than the length of the hollow tube body 10. During extrusion, the blended paste 11 is extruded into the cavity 13 from the end of the cavity away from the ejector pin 20, and the pressure and time of extrusion are controlled to ensure that the paste 11 fills the cavity 13 and adheres to the hollow tube body 10, and then the ejector pin 20 is pulled out to complete step S40. Figure 3 shown.

[0104] In this embodiment, preferably, after the mud 11 is formed, the mud 11 is squeezed into the cavity of the hollow tube body 10 by air pressure, hydraulic pressure or mechanical pressure and is integrally formed with the hollow tube body 10 until the mud 11 fills the hollow tube body 10 and contacts the ejector pin 20, and then the ejector pin 20 is pulled out of the hollow tube body 10 to obtain the semi-finished product of the heat-not-burn smoke-generating body of the present invention.

[0105] In another embodiment, when the paste is input into the hollow tube body 10 by mechanical means, the mechanical method adopts a motor screw-driven injection device, and the motor screw-driven injection device includes an extrusion tube, a motor pushing piston and a motor screw drive, and the extrusion tube is filled with paste 11.

[0106] In a specific embodiment, the extrusion device is a glue dispensing cylinder purchased from the market, which is connected to an air pipe through a pneumatic controller. The pneumatic controller is controlled to squeeze the smoking paste in the glue dispensing cylinder into the cavity of the hollow tube body 10 until the paste 11 fills from one end of the hollow tube body 10 to the other end and contacts the ejector pin 20, and then the ejector pin 20 is pulled out, and the paste 11 forms a columnar body in the hollow tube body 10.

[0107] The key point of the present invention is that in step S50, microwave or high-frequency heating is used to expand the semi-finished smoke body. The strong penetration of microwave or high frequency on materials can instantly heat the inside and outside of the smoke paste 11, so that the water inside the paste is quickly heated and vaporized and pressurized. When the steam pressure inside the paste reaches or exceeds the structural tension of the paste raw material cells, the cells will expand, thereby driving the overall expansion of the material to form a loose and uniform microporous structure. The microwave or high-frequency heating method can achieve a uniform heating effect in a short heating time without any heat conduction process.

[0108] In this embodiment, the microwave heating device used in step S50 is a microwave oven, the heating power provided by the microwave heating device is 1KW-100KW, the heating temperature provided by the microwave heating device is 30-80°C, and the heating time provided by the microwave heating device is 30-180 minutes. Preferably, the heating power provided by the microwave heating device is 10KW-20KW, the heating temperature is 45-60°C, and the heating time is 30-80 minutes. In other embodiments, the high-frequency heating device used in step S50 is a high-frequency baking oven, the frequency provided by the high-frequency heating device is 1-30 MHz, the heating temperature provided by the high-frequency heating device is 30-80°C, and the heating time provided by the high-frequency heating device is 30-180 minutes. Preferably, the heating frequency provided by the high-frequency heating device is 5-15 MHz, the heating temperature is 45-60°C, and the heating time is 30-80 minutes. In this step, the hollow tube body 10 of the columnar paste 11 is placed in a microwave oven or a high-frequency baking oven. The material is expanded by the microwave or high frequency to form tiny pores. Because the paste 11 expands inside and outside at the same time, the paste 11 material sticks to the inner wall of the hollow tube body 10 and forms an integrated structure with the hollow tube body 10.

[0109] In other embodiments, the microwave heating device or high-frequency heating device is used in step S50 to perform the heating process in a vacuum state. In a vacuum state, the boiling point of water molecules is reduced, which can accelerate the evaporation process of water and help the expansion of the paste. In the process of expanding the paste, the cell structure of the raw material is destroyed, and the macromolecular structure in the raw material is reduced. Since the main odor in the paste is mainly caused by the macromolecular structure, the smoke paste 11 can be kept under the uniform temperature control of the microwave heating device or the high-frequency heating device to obtain a good mellowing effect, eliminate the odor of the smoke paste and make it taste soft.

[0110] Next, in step S60, Figure 3The semi-finished smoke body shown in step S50 is puffed and then dried. In the present embodiment, the drying device used is a low-temperature oven, the temperature during drying is 40-80°C, and the drying time is 100-400 minutes. Preferably, the drying temperature of the drying device is 50-60°C and the drying time is 180-280 minutes. This process is low-temperature baking. If the temperature is too high, the hardness of the paste 11 after drying into the smoke body is too hard and cannot be inserted into the heating device for smoking the smoke body. If the temperature is too low, the baking time is too long, which is not conducive to production efficiency. Specifically, the paste 11 squeezed in the hollow tube 10 is expanded by microwave or high-frequency heating and baked at low temperature to form a semi-finished smoke body. The interior of the semi-finished smoke body is a loose pore structure with a porosity of 40-75%. The material organization within this porosity range is suitable for the softness and hardness of the smoke body, and the hardness of the formed smoke body makes the strength of inserting the smoke body into the heating device 0.8-2.0kgf. In addition, after the smoke-generating body is heated by microwave or high frequency and baked at low temperature, the paste 11 and the inner wall of the hollow tube 10 are bonded into a loose columnar body with a porosity of 40-75%. When the smoke-generating body is inserted into the heater for heating, the smoke-generating body fits more closely with the heating part, and the heating is more uniform, so that a better amount of smoke can be obtained. Moreover, the porosity of 40-75% allows the smoke generated by the smoke-generating body heated by the heater to pass smoothly, and obtain a suitable suction resistance. The suction resistance of the smoke-generating body in this embodiment is 1.0-1.5KPa. Preferably, the weight content of water in the formed smoke-generating body is 5-10%, so that the water vapor content of the smoke generated by heating by the heating device is small, and the smoke temperature is low without causing burns to the mouth. Preferably, the temperature during microwave or high frequency heating puffing and low temperature baking is not high, and does not exceed 50°C, so that the tobacco flavoring is less lost during the baking process and the taste restoration is better.

[0111] Finally, in step S70, a filter tip 12 is arranged at the other end of the hollow tube 10 relative to the paste 11, and the heated and unburned smoke-generating body of the present invention can be obtained. Figure 4 Preferably, the filter tip 12 is a sponge-like structure, which is used to filter tiny particles and allow smoke to pass smoothly.

[0112] In other embodiments, other processes may be added between step S60 and step S70 to produce different heated or unburned smoke products of the present invention. Figure 5 , Figure 5 FIG. 2 is a schematic diagram of an embodiment of a smoke-generating body heated or not burned according to the present invention. Figure 5 As shown, before setting the filter tip in step S70, a capsule support 14 and a capsule 15 are sequentially loaded into the cavity 13 of the hollow tube body 10, wherein the capsule support 14 is arranged along the center line of the paste 11 and contacts the paste 11, and the capsule 15 is filled with spices, one end of which contacts the capsule support 14, and the other end contacts the filter tip 12.

[0113] In this embodiment, the capsule support body 14 is a rolled column formed by winding a sheet material, and a plurality of layers are formed during the sheet material winding process, with gaps between the layers. The diameter of the capsule support body 14 is smaller than the inner diameter of the hollow tube body 10 .

[0114] Preferably, the capsule support 14 is made of a sheet material and is a soft structure. One end of the capsule support 14 contacts the paste 11, and the other end is close to the capsule 15 containing the flavor, which is used to position the capsule 15 containing the flavor and reduce the smoke temperature. In other embodiments, the capsule support 14 is made of a fluffy structure with a spiral cross section formed by winding a sheet of paper, a high temperature resistant film, aluminum foil, tin foil or polylactic acid material, and the capsule support 14 has a diameter of 1-9 mm, a length of 3-30 mm, and a gap of 0.1-1.5 mm.

Figure 6 As shown, in this embodiment, the capsule support body 16 is a hollow filter cotton. The capsule support body 16 and the capsule 15 are sequentially loaded through a compounding machine. The capsule support body 16 is arranged along the center line of the paste 11 and contacts the paste 11. The inner diameter of the hollow filter cotton is smaller than the outer diameter of the capsule 15, so that the capsule 15 can be fixed between the hollow filter cotton and the filter tip 12.

[0116] In each embodiment of the present invention, the capsule 15 is a spherical brittle capsule containing liquid fragrance inside, and the diameter of the spherical brittle capsule is 2.0-5.0 mm. Preferably, the capsule 15 includes a capsule membrane and a surface layer formed on the surface of the capsule membrane, and the capsule surface layer is a sealing treatment layer, and the sealing treatment layer is used to prevent the volatilization of the fragrance and maintain the durability of the fragrance.

[0117] Please refer to Figure 7 , Figure 7 FIG. 2 is another schematic diagram of another embodiment of the smoke-generating body heated or not burned according to the present invention. Figure 7 As shown, in the present embodiment, the capsule support 16 is a hollow filter cotton. The capsule support 16 and the capsule 15 are sequentially loaded through a compound machine. The capsule support 16 is arranged along the center line of the paste 11 and contacts the paste 11. The inner diameter of the hollow filter cotton is smaller than the outer diameter of the capsule 15. The capsule 15 is arranged in the groove formed by the filter tip 12, which is more convenient for being pinched when inhaling the heated or burned smoke-generating body of the present invention. The liquid flavor in the capsule 15 overflows and enters the oral cavity along with the smoke generated by the heated paste 11.

[0118] Of course, the various embodiments of the heat-not-burn smoke-generating body of the present invention can selectively add the capsule 15 or not add the capsule 15, and the heat-not-burn smoke-generating body of the present invention can be manufactured according to the choice of the consumer.

[0119] Please refer to Figure 8 , Figure 8 FIG. 2 is another schematic diagram of another embodiment of the smoke-generating body heated or not burned according to the present invention. Figure 8 As shown, in this embodiment, the above-mentioned implementation can be combined to set a plastic part 30 between the paste 11 and the capsule support 14, one end of the plastic part 30 is connected to the paste 11, and the other end is connected to the capsule support 14 to fix the capsule 15. Please refer to Figures 9 to 12 , Figures 9 to 12 Schematic diagram of different embodiments of the plastic resin portion 30 of the smoke-generating body heated or not burned according to the present invention. Figures 8 to 12 As shown, the material of the plastic part 30 of the present invention is a cylindrical substrate made of silicone, high temperature plastic or degradable polylactic acid PLA. The outer edge of the cylinder is bonded to the inner wall of the hollow tube 10. There are multiple gas channels in the cylinder for heating the smoke-generating body of the present invention. When the smoke-generating body is heated, the smoke generated by the heated paste 11 can smoothly pass through the plastic part 30, the capsule support 14, and the filter tip 12 to the user's mouth. The gas channel can be multiple circular or square channels, or a single star-shaped channel, such as Figures 9 to 12 As shown, the ratio of the areas 31, 41, 51, 61 of the cross-sectional circle of the fat plastic portion 30 occupied by the gas channels 32, 42, 52, 62 is 1:2 to 1:10. Preferably, the ratio of the areas 31, 41, 51, 61 of the cross-sectional circle of the fat plastic portion 30 occupied by the gas channels 32, 42, 52, 62 is 1:3.

[0120] In addition, tobacco leaves are the main source of nicotine. In the present invention, a small amount of tobacco leaf components can be added to the herbal raw materials for preparing the paste 11. The paste 11 mainly provides nicotine components. By heating the paste 11, the nicotine components in the tobacco leaves are brought into the smoke, which can make smokers feel satisfied with the nicotine components. Tea leaves are used as a carrier of the paste 11. The different proportions of the components in the tea leaves will result in different concentrations of tobacco leaf components, thereby adjusting the nicotine concentration in the smoke. Of course, the present invention can also add nicotine or nicotine salts to the herbal raw materials for making the paste 11, or after the paste 11 is injected into the hollow tube 10, the nicotine or nicotine salt components on the surface of the paste 11 can also provide smokers with a sense of satisfaction from smoking nicotine components.

[0121] In addition, different raw material components can be added to the herbal raw materials or Chinese medicinal herbs according to the functional needs of the user. If the user has symptoms of rhinitis, one or a combination of ingredients of Herba Stemonae, Asarum, Fructus Xanthium, Chrysanthemum, Menthol, Mint Leaf, Borneol, etc. can be added to the herbal raw materials or Chinese medicinal herbs; if the user has symptoms of cough and bronchitis, one or a combination of ingredients of Herba Stemonae, Apricot, Morus Alba, Platycodon, Fritillaria, Houttuynia, Forsythia, Loquat Leaf, etc. can be added to the herbal raw materials or Chinese medicinal herbs; if the user has symptoms of sore throat, one or a combination of ingredients of Herba Tangerineae, Gardenia, Licorice, Monk Fruit, Sterculia Lycopodiella, etc. can be added to the herbal raw materials or Chinese medicinal herbs; if the user has symptoms of chronic pharyngitis, one or a combination of ingredients of Herba Loquatae, Fructus Momordicae, Fructus Honeysuckle, Poria, Sterculia Lycopodiella, Platycodon, Mint, Licorice, Taraxaci, etc. can be added to the herbal raw materials or Chinese medicinal herbs; if the user needs nourishing health care, one or a combination of ingredients of Herba Stemonae can be added to the herbal raw materials or Chinese medicinal herbs. Add one or a combination of cordyceps, ginseng, ganoderma, agarwood, American ginseng, deer antler, eucommia, Panax notoginseng, polygonatum, etc. to the raw materials or Chinese medicinal herbs; if the user needs medicinal and health care, add one or a combination of yew, Kalanchoe, etc. to the raw materials or Chinese medicinal herbs; even if the user wants to quit smoking, add one or a combination of houttuynia, earthworm, polygala, patchouli, licorice, etc., or one or a combination of Pseudostellaria zizi, mint, earthworm, houttuynia, polygala, baking soda, tea, etc., or one or a combination of green tea, mint, patchouli, licorice, etc., or one or a combination of tea, honeysuckle, chrysanthemum, wormwood, perilla, lotus leaf, monk fruit, etc., or one or a combination of Scutellaria barbata, earthworm, sanguisorba officinalis, etc.

[0122] In addition, since the water content of the paste 11 used in the above-mentioned embodiment of the smoke-generating body heated or not burned by the present invention is higher than that of the prior art, and in the embodiment using the capsule 15, after the capsule 15 is broken, the liquid fragrance flowing out of the capsule will cause water to seep out of the surface of the hollow tube 10. Please refer to Fig.13 , Fig.13 FIG. 2 is another schematic diagram of another embodiment of the smoke-generating body heated or not burned according to the present invention. Figure 8 As shown, in this embodiment, after the semi-finished product of the heated or otherwise burned smoke-generating body of the above-mentioned embodiments is made, a layer of label paper 70 can be pasted on the outside of the hollow tube 10, and before the hollow tube 10, the capsule support body 14, and the filter cotton 12 are connected, a layer of food-grade quick-drying glue is first applied on the label paper 70, and then the hollow tube 10, the capsule support body 14, and the filter cotton 12 with the capsule 15 are connected together, thereby obtaining the finished product of the heated or otherwise burned smoke-generating body of the present invention. In other embodiments, the label paper 70 can also be a label paper 70 with food-grade self-adhesive glue thereon, and then the hollow tube 10, the capsule support body 14, and the filter cotton 12 with the capsule 15 are connected together, thereby obtaining the finished product of the heated or otherwise burned smoke-generating body of the present invention.

[0123] In this embodiment, the label paper 70 is an impermeable base paper and an ink layer, and the material is selected from odorless, tasteless, and non-toxic materials, and the glue pasted on the smoke body is selected from food-grade quick-drying glue or self-adhesive glue, which is harmless to the human body during the suction process. The gram weight of the impermeable base paper per square meter is 20-60 grams / ㎡, preferably, the gram weight of the impermeable base paper per square meter is 25-45 grams / ㎡, and the ink is food-grade ink. Since the impermeable base paper is difficult to absorb moisture, the water-absorbing material in the smoke body is prevented from absorbing moisture from the air through the hollow tube body and the label paper, thereby making the smoke body damp, so that the heated or not burned smoke body of the present invention is beautiful, and bacteria or mold will not grow on the surface of the smoke body due to liquid penetration of the hollow tube body 10. In addition, when the paste occupies 100% of the length of the entire smoke body, the smoke body, the capsule support body, the capsule or the filter tip without the capsule can also be connected together through the label paper 70 to obtain the finished cigarette of the heated or not burned smoke body of the present invention.

[0124] Compared with the prior art, the method for preparing a smoke-generating body heated and not burned according to the present invention and the smoke-generating body prepared have the following beneficial effects:

[0125] 1. Through microwave or high-frequency heating, the strong penetration ability of microwave or high frequency on materials can be used to heat the inside and outside of the smoking paste at the same time. The heating time is short and the effect of uniform heating can be achieved without any heat conduction process. Under vacuum heating, the smoking paste is aged to eliminate the peculiar smell of the smoking paste and make its taste soft. In this method, the smoking paste is baked together with the tube body to form a smoking body with a loose pore structure, suitable suction resistance, and suitable for heating tools to be easily inserted into the smoking body, thereby enhancing the user experience. In addition, microwave or high-frequency heating has a good sterilization effect.

[0126] 2. The use of microwave or high-frequency heating equipment occupies a small area and is simple to operate. It not only reduces the overall preparation cost, but also avoids high environmental temperatures and has the advantages of being pollution-free, energy-saving, and the products are not easy to deteriorate or moldy, which is conducive to long-term storage.

[0127] 3. Obtain good smoking resistance. The suction resistance of the heat-not-burn non-smoking or tobacco product is between 0.75-1.5Kpa, which is basically the same as the suction resistance of traditional lit cigarettes, thereby obtaining a good suction effect.

[0128] 4. The heat-not-burn non-smoke or tobacco product is smoked by heating at 200-300°C. When heated at 200-300°C, the herbal raw materials, Chinese herbal medicine or tobacco raw materials will not decompose and are beneficial to physical and mental health. No harmful substances such as tar will be generated during the heating process.

[0129] 5. Since the water content inside the smoke body is low, 5-10%, the aerosol temperature generated by the heater is low and will not burn the consumer's mouth. At the same time, the liquid flavor in the capsule can supplement the aerosol aroma generated by the smoke body to form a pleasant aerosol.

[0130] 6. The heated or otherwise burned smoke body of the present invention is provided with an anti-penetration label paper, which can prevent the smoke body from absorbing moisture in the air and becoming damp, and the overall appearance is beautiful, and bacteria or mold will not grow on the surface of the smoke body due to the dampness of the smoke body in the tube.

[0131] It should be noted that the present invention is not limited to the above-mentioned embodiments. According to the creative spirit of the present invention, those skilled in the art may also make other changes, which should not be interpreted as limiting the scope of the present invention. It should be noted that all changes and substitutions equivalent to the embodiment should be included in the scope of the present invention.
