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 disordered aerosol generating substrate. BACKGROUND

[0002] With the importance of health problems and the 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 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. Its core is the smoke core section, which produces aroma and smoke by heating, directly determines 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, the forming method of the smoke core section of the heating cigarette includes two kinds: ordered processing technology and disordered processing technology. The ordered processing technology is mainly to prepare reconstituted tobacco leaf sheet first, suck the smoking agent and dry, and then cut into a certain width of reconstituted tobacco leaf silk and gather into shape. The disordered processing technology is to mix reconstituted tobacco leaf and natural tobacco leaf raw materials to make silk, suck the smoking agent and dry, and then use the modified traditional rolling machine group to roll. Although the ordered processing technology and the disordered processing technology have higher flexibility and adaptability, they also face many technical problems.

[0004] Firstly, the physical strength of the mixed tobacco in the disordered processing technology will be significantly reduced after sucking the smoking agent, and the tobacco becomes soft. In addition, during the preparation and storage process, the smoking agent in the tobacco is also easy to exude to the surface of the tobacco, or in the case of high environmental humidity, the mixed tobacco is easy to absorb the moisture in the air, which will cause the physical strength to be significantly reduced and the tobacco to be soft. The reduction of the physical strength of the mixed tobacco will cause the following problems: 1. The filling amount of the mixed tobacco is difficult to control. If the filling amount is too small, the smoke core section will be too soft, which will affect the smoking experience; if the filling amount is too large, the tobacco will be filled too tightly, which will increase the resistance and also affect the smoking effect. 2. Due to the low physical strength of the mixed tobacco, the tobacco crushing rate will also increase, which will cause the problem of tobacco falling off the end of the smoke core section. This not only affects the appearance quality of the cigarette, but also may cause the tobacco to scatter during smoking, which will affect the smoking experience. 3. In addition, the absorption of moisture in the air by the mixed tobacco will also cause the smoke amount of the mixed tobacco to decrease and the smoke temperature to increase.

[0005] Secondly, in the mixing process of disordered processing, the smoking agent is easy to exude to the surface of the cigarette paper during storage and transportation, forming a yellow spot. This 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, it is usually necessary to separately set a barrier layer on the inside of the cigarette paper, which undoubtedly increases the production cost and process complexity. In addition, during the storage and transportation of the mixed cut tobacco, the internal effective components (such as smoking agents, aroma components, etc.) will also volatilize and lose, resulting in a short shelf life and a decrease in quality when filled into the aerosol generating article.

[0006] In summary, although the disordered processing process has certain advantages in the formation of the heating cigarette core segment, there are still many technical problems to be solved. 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 mixed cut tobacco, but also effectively prevent the exudation of the smoking agent, for improving the quality and smoking experience of the heating cigarette.

[0007] In addition, in order to achieve the smoking amount and aroma quality, the main body of the existing disordered mixed cut tobacco can only be reconstituted tobacco and natural cut tobacco, and the selection of raw materials is limited.

[0008] In order to solve the above problems, the utility model is proposed. Utility model content

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 aerosol generating articles 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 quality of smoking is ensured, however, the functional substance layer 23 coated on both sides of the paper base body 22 makes the paper base body 22 soft, and the problems of difficult control of the filling amount of mixed cut tobacco, high cut tobacco crushing rate and easy falling of tobacco from the end of the tobacco core 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 is mixed with natural tobacco and cut, and is used in aerosol generating articles, the amount of smoke and the aroma quality are excellent, and the paper-based smoking tobacco can completely replace reconstituted tobacco and be used in aerosol generating articles.

[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 spices or porous materials loaded with essence and spices. The liquid component is responsible for smoking and strength, the solid component is used as an aroma skeleton, and the essence and spices loaded in the porous materials can further improve the slow-release effect of aroma.

[0052] 3、The utility model discloses a paper base body 22 surface with functional material layer 23 is coated, and the coating layer can improve the physical strength of paper base smoking tobacco from three aspects, first, the utility model discloses in paper base body 22 coating functional material (such as smoking agent) drying again and then coating coating layer, and the coating layer can improve the physical strength of paper base smoking tobacco, avoids paper base body 22 to absorb smoking agent and become soft. Second, the coating layer prevents the internal smoking agent (only is with smoking agent example, also includes essence etc.) of paper base smoking tobacco and exosmosis to paper base smoking tobacco surface. Third, the coating layer can effectively prevent the passage of moisture in the air, make internal paper base body 22 and functional material layer 23 with outside isolation, effectively reduce paper base body 22 hygroscopicity. Avoided the problem of paper base smoking tobacco physical strength drop from three aspects, thereby solve the difficult control of paper base smoking tobacco filling capacity, the high tobacco shred rate of tobacco, and the problem of easy appearance tobacco core section end thread drop. In addition, avoid paper base smoking tobacco to absorb moisture in the air, also avoided the problem of paper base smoking tobacco smoke amount drop, smoke temperature increase.

[0053] 4、The utility model discloses paper base smoking tobacco surface coating layer can prevent the internal smoking agent of paper base smoking tobacco and exosmosis to paper base smoking tobacco surface, also avoided the problem of smoking agent exosmosis and produce yellow spot on cigarette paper, need not set up again and prevent the layer on cigarette paper, reduce the requirement of cigarette paper.

[0054] 5、The utility model discloses paper base smoking tobacco surface coating layer also can play the role of locking paper base smoking tobacco internal component (such as smoking agent, aroma component etc.), avoided paper base smoking tobacco internal component volatilization loss in the process of placing.

[0055] 6、The utility model discloses coating material is selected from ethyl cellulose, and the coating layer formed by this material not only can effectively prevent the passage of moisture. Also have certain permeability, so when paper base smoking tobacco is heated and produces aerosol, and the aerosol still can smoothly pass through coating layer and gradually release, will not influence paper base smoking tobacco self's smoking amount.

[0056] 7、The utility model discloses coating layer material's dosage and preparation condition in coating process, guarantee the uniformity of coating layer, and the dosage and uniformity of coating layer also very big to the influence of volatility. If coating layer dosage is too big or coating layer is not uniform, possibly will hinder the release of volatile substance. But proper coating layer dosage and uniformity can ensure that volatile substance can smoothly pass through coating layer when being heated.

[0057] 8. The filter element of the present invention has fragrance-enhancing beads inside. Since an end cavity is provided downstream of the filter element, the positioning requirements for the fragrance-enhancing beads when applying them inside the filter element are reduced. Even if the fragrance-enhancing beads are close to the downstream end face of the acetate fiber tow filter section (the end face facing the lip end), or even exposed from the downstream end face of the acetate fiber tow filter section, due to the presence of the end cavity, they will not flow out after being pinched, and the fragrance-enhancing substances in the end cavity can also play a role in flavoring the smoke when the smoke passes through. The utility model provides an end cavity downstream of the filter element, which reduces the process difficulty of adding the fragrance-enhancing beads inside the filter element.

[0058] 9. The inscribed diameter of the cavity 51 of the end cavity member 5 of the present invention is smaller than the diameter of the flavoring beads 421, thereby ensuring that the flavoring beads 421 do not fall out of the cavity. Furthermore, when the end cavity member 5 has a cavity located on the central axis, the cross-sectional shape of the cavity is preferably a special non-circular shape such as a heart, star, polygon, or flower. This is to provide a larger smoke channel to reduce interception while also blocking the flavoring beads 421 in the upstream filter member 42. For irregular shaped cavities, it is sufficient to ensure that the inscribed diameter of the cavity is smaller than the diameter of the flavoring beads 421.

[0059] In addition, the special-shaped end cavity can also increase the recognition and interest of the aerosol-generating product.

[0060] 10. In the present invention, a flavoring component is provided in the support member, and flavoring beads are added to the filter member, wherein the flavoring beads in the filter member play the role of supplementing the aroma of the flavoring component in the support member and changing the flavor type in the middle and late stages of smoking. Specifically, the blocking member in the early stage of smoking is for smoke flavoring. When the consumer feels that the aroma is not supplemented enough, the beads can be manually pinched to add flavor to the smoke in the latter half, thereby playing the role of aroma supplement in the latter half. Furthermore, the aroma and flavor characteristics of the flavoring component in the support member and the flavoring beads in the filter member may be inconsistent, thereby playing the role of changing the style characteristics before and after smoking. For example, the flavor characteristic of the flavoring component in the support member is fruity, while the flavor characteristic of the flavoring beads in the filter member is chocolate. In this way, when the consumer feels that the fruity flavor is not obvious during smoking, he or she can manually pinch the flavoring beads to change to chocolate flavor in the latter half of smoking.

[0061] 11. The present invention sets an end cavity member downstream of the filter member. The end cavity member extends the distance from the aerosol generating matrix section to the mouth end. Therefore, the temperature of the outer surface of the end cavity member is lower than that of the filter member surface, thereby avoiding the problem of the mouth end surface of the aerosol generating product being hot.

[0062] 12、The utility model discloses end cavity piece inside has hollow airflow passageway, its interception to flue gas is little, so flue gas stays short time in end cavity piece, also avoided the problem that aerosol generating article mouth end surface scalds mouth to aerosol generating article mouth end surface, further avoided aerosol generating article mouth end surface scalds mouth's problem. Simultaneously, because end cavity piece's interception to flue gas is little, so set up end cavity piece downstream in filter piece and will not obviously increase the suction resistance of filter piece.

[0063] 13、The utility model discloses end cavity piece is hollow acetate fiber tow pipe, hollow paper tube or hollow non - woven fabric pipe, because its inside hollow, reduced the material area of contact with consumer's oral cavity, reduced consumer's safety doubt.

[0064] 14、On the preparation method, the utility model discloses first using compound machine utilizes the forming paper 43 and carries out the compound of hollow cooling piece 41 and filter piece 42 to obtain the compound cooling filter piece 4, then uses compound machine and utilizes the outer wrapping paper 1 and is compounded aerosol generating substrate 2, support piece 3, compound cooling filter piece 4 and end cavity piece 5, the utility model discloses can prepare five aerosol generating articles on the basis of not changing the original four compound equipment.
