Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of heating non - combustible cigarette, specifically relates to an aerosol generating product containing paper base smoking silk ordered aerosol generating substrate. BACKGROUND

[0002] With the importance of health problems and the increasing demand of consumers for personalized experience of cigarette products, the tobacco industry has been responding to the demand of consumers, and various smoking products with reducing tar and harm have been developed. As a new type of tobacco product, heating non-combustible cigarette has received extensive attention and research in the tobacco industry in recent years. The core is the smoke core section, which generates aroma and smoke by heating, directly determining the style characteristics and quality of the heating cigarette. Therefore, the forming method of the smoke core section has become one of the research hotspots.

[0003] At present, in addition to the granular heating non-combustible cigarette, there are two forming methods of the smoke core section of the heating cigarette: ordered processing technology and disordered processing technology. The ordered processing technology is to prepare reconstituted tobacco leaf sheet first, absorb the smoking agent and dry it, and then cut it into a certain width of reconstituted tobacco leaf silk and gather it into shape. The disordered processing technology is to mix reconstituted tobacco leaf and natural tobacco leaf raw materials to make silk, absorb the smoking agent and dry it, and then use the modified traditional rolling machine group for rolling. Although the ordered processing technology and the disordered processing technology have higher flexibility and adaptability, they also face many technical problems.

[0004] Firstly, after the reconstituted tobacco leaf sheet in the ordered processing technology absorbs the smoking agent, its physical strength will be significantly reduced, and the reconstituted tobacco leaf sheet will become soft. In addition, during the preparation and storage process of the reconstituted tobacco leaf sheet, the smoking agent inside the reconstituted tobacco leaf sheet is also easy to exude to the surface of the reconstituted tobacco leaf sheet, or in the case of high environmental humidity, the reconstituted tobacco leaf sheet is easy to absorb moisture in the air. These problems will cause the physical strength to be significantly reduced, and the reconstituted tobacco leaf sheet will become soft. The reduction of the physical strength of the reconstituted tobacco leaf sheet will lead to the difficulty in controlling the filling amount of the reconstituted tobacco leaf silk after cutting. If the filling amount is too small, the smoke core section will be too soft, affecting the smoking experience; and if the filling amount is too large, the tobacco silk will be filled too tightly, increasing the resistance, which also affects the smoking effect. Under the condition of constant weight, the stiffness of the smoke core rod is poor.

[0005] Secondly, the exudation of the smoking agent inside the reconstituted tobacco leaf silk to the surface of the reconstituted tobacco leaf silk, or in the case of high environmental humidity, the reconstituted tobacco leaf silk absorbs moisture in the air, will cause the surface of the reconstituted tobacco leaf silk to be damp, and the silk and silk to be sticky, affecting the ordered gathering process. In addition, the absorption of moisture in the air by the reconstituted tobacco leaf silk will also cause the smoke amount of the reconstituted tobacco leaf silk to decrease, and the smoke temperature to increase.

[0006] Finally, during storage and transportation, the smoking agent of the reconstituted tobacco shred is prone to exosmosis to the surface of the cigarette paper to form yellow spots, which not only affects the appearance of the cigarette, but also may have an adverse effect on the taste of the cigarette. In order to solve this problem, a separate impermeable layer usually needs to be provided on the inner side of the cigarette paper, which undoubtedly increases the production cost and process complexity. In addition, during storage and transportation, the internal effective components (such as smoking agents, aroma components, etc.) of the reconstituted tobacco shred also volatilize and lose, resulting in a short shelf life and a decrease in quality when filled into the aerosol generating article.

[0007] Therefore, it is of great significance to develop a new type of heating cigarette core segment forming method which can not only maintain the stability of the physical strength of the reconstituted tobacco shred, but also effectively prevent the exosmosis of the smoking agent, to improve the quality and smoking experience of the heating cigarette.

[0008] In addition, in order to achieve the smoking amount and aroma quality, the main body of the existing ordered aerosol generating substrate can only be reconstituted tobacco, and the selection of raw materials is limited.

[0023] Preferably, the support 3 has a flavoring component, which is a porous material adsorbing essence spices.

[0027] More preferably, the flavoring component is a porous material adsorbing essence spices, which is coated on the inner wall of the support or the groove corrugated layer sheet material according to actual conditions.

[0029] The inner tangent circle diameter of the cavity 51 is smaller than the diameter of the flavor-enhancing burst 421, so as to ensure that the flavor-enhancing burst 421 will not fall out of the cavity. Here, the inner tangent circle diameter of the cavity 51 is required to be smaller than the diameter of the flavor-enhancing burst 421, that is, the size of the burst that can pass through the cavity is smaller than the diameter of the burst added in the filter 42 of the utility model.

The external air enters the hollow interior of the hollow cooling element 41 through the ventilation hole and is combined with the smoke.

[0048] Preferably, in step S1 and step S2, the drying conditions include placing it in an oven for drying, or air-drying with dry air. The drying conditions in the oven are: placing it in an oven at 45-60°C and baking it for 5-10 minutes; the air-drying conditions in dry air are: air-drying it with dry air at 45-60°C for 5-10 minutes.

[0049] Compared with the prior art, the paper-based smoking tobacco has the following beneficial effects:

[0050] 1. The paper-based smoking tobacco comprises a paper base body 22, the paper base body 22 is provided with a functional substance layer 23 on both sides, and the functional substance layer 23 is provided with a coating layer 24 on the outer side. The paper base body 22 is used to replace reconstituted tobacco in the aerosol generating article for the first time, but the paper base body 22 itself does not have the functions of smoking and producing aroma, the paper base body 22 is further used as a carrier, the functional substance layer 23 is coated on both sides of the paper base body 22, the functional substance in the functional substance layer produces aroma and smoke, and the smoking quality is ensured, however, the functional substance layer 23 coated on both sides of the paper base body 22 will cause the paper base body 22 to become soft, and then the problems that the filling amount of the paper-based smoking tobacco is difficult to control and the stiffness of the tobacco core rod is low under the condition of the quantitative gram weight are caused, the coating layer 24 is further formed on the outer side of the functional substance layer 23 to ensure the physical strength of the paper-based smoking tobacco. The paper-based smoking tobacco sheet obtained by cutting the paper-based smoking tobacco is used in the aerosol generating article, the smoking amount and aroma quality are excellent, and the paper-based smoking tobacco can completely replace reconstituted tobacco for use in the aerosol generating article.

[0051] 2. The functional substance layer 23 of the paper-based smoking tobacco comprises one or more of tobacco extract, a smoking agent, tobacco powder, essence and flavor or a porous material loaded with essence and flavor. The liquid component is responsible for smoking and strength, the solid component serves as an aroma skeleton, and the loading of the essence and flavor into the porous material can further improve the slow-release effect of the aroma.

[0052] 3. The paper base body 22 with the functional substance layer 23 is coated, after the paper-based smoking tobacco sheet is cut into the paper-based smoking tobacco, the coating layer on the surface of the paper-based smoking tobacco can improve the physical strength of the paper-based smoking tobacco from three aspects, first, the coating layer can improve the physical strength of the paper-based smoking tobacco, and avoid the softening of the paper base body 22 after absorbing the smoking agent, the coating layer is coated after the paper base body 22 is coated with the functional substance (such as the smoking agent) and dried. Second, the coating layer prevents the internal smoking agent (only the smoking agent is taken as an example, and essence and the like are also included) of the paper-based smoking tobacco from exuding to the surface of the paper-based smoking tobacco. Third, the coating layer can effectively prevent the passage of moisture in the air, so that the paper base body 22 and the functional substance layer 23 in the inside are isolated from the outside, and the hygroscopicity of the paper base body 22 is effectively reduced. The problem that the physical strength of the paper-based smoking tobacco is reduced is avoided from three aspects, so that the problem that the filling amount of the paper-based smoking tobacco is difficult to control is solved, the stiffness of the tobacco core rod is ensured under the condition of the quantitative gram weight, and the problem that the ordered tobacco core rod becomes soft due to the low stiffness is avoided.

[0053] 4. The coating layer on the surface of the paper-based smoking tobacco can prevent the paper-based smoking tobacco from absorbing moisture and becoming sticky, avoid the adhesion between the tobaccos, and ensure the orderly gathering.

[0054] 5. The coating layer on the surface of the paper-based smoking tobacco can prevent the internal smoking agent of the paper-based smoking tobacco from exuding to the surface of the paper-based smoking tobacco, and avoid the problem of yellow spots caused by the exudation of the smoking agent to the cigarette paper.

[0055] 6. The coating layer on the surface of the paper-based smoking tobacco can also lock the internal components (such as the smoking agent and aroma components) of the paper-based smoking tobacco, and avoid the volatilization and loss of the internal components of the paper-based smoking tobacco during storage.

[0056] 7. The coating material is ethyl cellulose, and the coating layer formed by the material can not only effectively prevent the passage of moisture, but also has certain air permeability, so that the aerosol generated by the paper-based smoking tobacco can still pass through the coating layer and be gradually released, without affecting the smoke yield of the paper-based smoking tobacco.

[0057] 8. The amount of the coating layer material and the preparation conditions in the coating process ensure the uniformity of the coating layer, and the amount and uniformity of the coating layer also greatly affect the volatilization rate. If the amount of the coating layer is too large or the coating layer is not uniform, it may hinder the release of volatile substances. However, appropriate amount and uniformity of the coating layer can ensure that the volatile substances can smoothly pass through the coating layer when heated.

[0058] 9. The filter element has a flavoring burst bead, and the downstream end cavity element is arranged below the filter element, so that the positioning requirement of the flavoring burst bead is reduced when the flavoring burst bead is arranged in the filter element. Even if the flavoring burst bead is close to the downstream end surface of the acetate fiber bundle filter section (the end surface on the side facing the lip end), or even exposed from the downstream end surface of the acetate fiber bundle filter section, the flavoring substance in the end cavity element will not flow out after being pinched, and the flavoring substance in the end cavity element can also play a role in flavoring the smoke when the smoke passes through. The end cavity element arranged downstream of the filter element reduces the technical difficulty of adding the flavoring burst bead in the filter element.

[0059] 10、The utility model discloses the inscribed circle diameter of the cavity 51 of the end cavity piece 5 is less than the diameter of the flavoring burst bead 421, so as to guarantee that the flavoring burst bead 421 does not fall out of the cavity. Further, when the end cavity piece 5 has a cavity at the central axis, the cross section of the cavity is preferably a special shape such as a heart shape, a star shape, a polygonal shape, a flower shape or other non-circular special shape, which aims to provide a larger smoke passage and reduce the interception, and at the same time, the flavoring burst bead 421 in the filter piece 42 upstream can be blocked. As long as the inscribed circle diameter of the cavity is less than the diameter of the flavoring burst bead 421, the cavity can be of any special shape.

[0060] In addition, the special-shaped end cavity can also increase the recognition and interest of the aerosol generating article.

[0061] 11、The utility model discloses the flavoring component is arranged in the support piece, and the flavoring burst bead is added in the filter piece, wherein the flavoring burst bead in the filter piece plays a role of supplementing the aroma of the flavoring component in the support piece and converting the fragrance type in the later stage of smoking. Specifically, the blocking piece is flavored in the early stage of smoking, and when the consumer feels that the aroma is insufficient, the burst bead can be manually pinched to break, thereby flavoring the smoke in the latter half and achieving the effect of aroma supplement in the later stage. Further, the aroma flavor characteristics of the flavoring component in the support piece and the flavoring burst bead in the filter piece can be inconsistent, thereby achieving the effect of style characteristic conversion before and after smoking. For example, the flavor characteristics of the flavoring component in the support piece are fruit flavor, and the flavor characteristics of the flavoring burst bead in the filter piece are chocolate flavor. In this way, when the consumer feels that the fruit flavor style is not obvious during smoking, the flavoring burst bead is manually pinched to break, thereby changing to chocolate flavor in the latter half of the smoking process.

[0062] 12、The utility model discloses the end cavity piece is arranged downstream of the filter piece, the end cavity piece prolongs the distance from the aerosol generating substrate section to the mouth end, so that the temperature of the outer surface of the end cavity piece is lower than that of the surface of the filter piece, thereby avoiding the problem of scalding the mouth with the surface of the mouth end of the aerosol generating article.

[0063] 13、The utility model discloses that the end cavity piece has a hollow airflow passage inside, which has a small interception of smoke, so that the smoke stays in the end cavity piece for a short time, thereby avoiding the heat from being transferred to the outer surface by the smoke, and further avoiding the problem of scalding the mouth with the surface of the mouth end of the aerosol generating article. At the same time, since the end cavity piece has a small interception of smoke, the end cavity piece arranged downstream of the filter piece does not significantly increase the suction resistance.

[0064] 14、The utility model discloses that the end cavity piece is a hollow acetate fiber tow tube, a hollow paper tube or a hollow non-woven fabric tube, since it is hollow inside, the area of the material in contact with the consumer's oral cavity is reduced, thereby reducing the safety concerns of the consumer.

[0065] 15、Preparation method, the utility model uses the composite machine to utilize the forming paper 43 to carry out the composite of the hollow cooling piece 41 and the filter piece 42 to obtain the composite cooling filter piece 4, then uses the composite machine to utilize the outer wrapping paper 1 to composite aerosol generating substrate 2, support piece 3, composite cooling filter piece 4 and end cavity piece 5, the utility model can prepare five-element aerosol generating product on the basis of not changing the original four-element composite equipment.
