technical field

The present application relates to the field of cigarettes, in particular to a heat-not-burn cigarette.

Background technique

Heating not burning cigarettes, different from traditional cigarettes, "low temperature cigarettes" designed with the idea of "heating not burning" can heat the tobacco leaves just enough to give off the flavor without igniting the tobacco leaves. Under normal circumstances, ordinary cigarettes will produce many harmful substances at a high temperature of 350 ℃ to 600 ℃ when smoking, while low-temperature cigarettes are below 300 ℃, and the harmful substances will be reduced. Specifically, taking the emissions as an example, heat-not-burn cigarettes are only about 5% of conventional cigarettes. From a cytotoxicity perspective, heat-not-burn cigarettes are about 14% of conventional cigarettes.

In addition, the taste and smoking experience of heat-not-burn products are closer to traditional cigarettes, which can make smokers feel the real tobacco taste and are easier to accept.

As mentioned above, heat-not-burn cigarettes use an external heat source to heat the tobacco rather than ignite the tobacco to produce tobacco flavor gas. Crucially, heat-not-burn cigarettes need to be equipped with special smoking equipment, and the heating temperature and time can be controlled more precisely, so that "heat-not-burn" can be realized.

In the prior art, when a user smokes a heat-not-burn cigarette, it is usually necessary to insert the cigarette into the heat-not-burn smoking device, and then the heat-not-burn smoking device heats the cigarette for the user to smoke. During the actual use of the HNB device, when the user moves the cigarette by holding the cigarette, or inserts and pulls the cigarette into the HNB device, the fillers such as tobacco leaves in the cigarette are often different from the model of the cigarette and the smoking device. Matching, or the tobacco leaves in the cigarettes are not compact enough, etc., the fillers such as tobacco leaves fall to the outside of the cigarettes. If it falls outside the heat-not-burn smoking device, the user's smoking experience will be affected due to the reduction of the filler; if it falls into the heat-not-burn smoking device, it will not only affect the user's smoking experience, but also affect the normal use of the user. Heat-not-burn smoking devices are affected.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , an embodiment of the present application provides a heat-not-burn cigarette. The cigarette includes a filter rod disposed at one end of the cigarette, a plug disposed at the other end of the cigarette, and a plug disposed between the filter rod and the plug. Tobacco sticks between.

Wherein, the filter rod is one end of the cigarette that is close to the user's mouth. When smoking, the user needs to hold the filter rod in the mouth, and then realize the smoking process through the suction action. At this time, the filter rod will filter the harmful substances ingested by the user through the cigarette, for example, harmful substances such as nicotine and tar.

The filter rod can be composed of a single structure or material, or can be a composite filter rod composed of multiple different structures or materials. For example, the filter rod can include three parts: a proximal filter rod, a hollow filter rod and a paper filter rod. The filter rod near the mouth end is arranged at the outermost end of the cigarette, one end of the hollow filter rod is connected with one end of the filter rod near the mouth end, the other end is connected with one end of the paper filter rod, and the other end of the paper filter rod is connected with the cigarette One end of the strip is connected. The proximal filter rod is the end that the user holds in the mouth when smoking.

In the embodiment of the present application, the material of the filter rod at the proximal end may be acetate fiber. In an implementation manner, the material of the hollow filter rod can also be the same material as that of the filter rod at the proximal end, such as acetate fiber. The interior of the hollow filter rod has a hollow structure, wherein the hollow structure means that the cross section of the hollow filter rod contains through holes. Wherein, there may be one or more through holes, and the shape of the through holes may be circular, square, diamond, etc., which is not limited herein.

The tow made of acetate fiber is used to make the filter rod, which has the advantages of good elasticity, non-toxic and tasteless, high thermal stability, low suction resistance, and can selectively absorb harmful substances in cigarettes. While filtering harmful substances, it also retains a certain amount of nicotine without losing the taste of cigarettes. Of course, the material of the filter rod near the mouth end and the hollow filter rod can also be made of other materials such as polypropylene, which is not limited here. The internal structure of the hollow filter rod is hollow, which can effectively reduce the suction resistance of the user when smoking, and improve the user's experience.

The material of the paper filter rod can be paper fiber. During production, firstly, wood pulp or waste paper scraps can be opened, bonded, and dried to form paper sheets, and then the paper sheets can be rolled into paper filter rods. It should be noted that the above is only one way of manufacturing the paper filter rod in the embodiment of the present application, and other technologies known to those skilled in the art may also be within the protection scope of the embodiment of the present application. For example, when making paper sheets, plant fibers such as straw fibers, straw fibers, and wheat straw fibers can be added. The paper filter rod not only has low cost, but also has excellent tar retention performance, which can effectively filter the substances when users smoke.

In the embodiments of the present application, the paper filter rod may be composed of only paper fibers, or may be composed of paper fibers and other materials. For example, the paper filter plug may be composed of paper fibers and acetate fibers, with the acetate fibers at the proximal end and the paper fibers at the other end. The composite filter rod not only has the high adsorption of paper fibers, but also has higher filtration efficiency per unit pressure drop than the acetate fiber filter rod. Of course, in addition to acetate fibers, other additives and paper fibers can also be added to form composite filter rods.

By connecting the filter rod at the mouth end, the paper filter rod and the hollow filter rod to form a composite filter rod, the high adsorption performance of the paper filter rod can be used to absorb harmful substances in tobacco leaves, and the hollow filter rod can be used to reduce the number of users. The suction resistance improves the user experience. Among them, when connecting the filter rod near the mouth end, the paper filter rod and the hollow filter rod, they can be connected and fixed by forming paper. First, the filter rod, hollow filter rod and paper filter rod can be connected together at the near-mouth end, and then after adding molding paper to the outer circumference of the filter rod, the molding paper can be fastened on the outer surface of the filter rod, so as to close the mouth-end. The filter rod, the hollow filter rod and the paper filter rod are connected and fixed together. After the various parts of the filter rod are connected and fixed by the shaping paper, a circle of tipping paper can be wrapped around the outer surface of the shaping paper. The tipping paper can make it easier for the user to distinguish which end of the cigarette is near the mouth when smoking, and also according to the different needs of the user, the tipping paper of different materials can be used to satisfy the user's mouth when holding a cigarette. Different requirements for touch. The connection relationship between the above-mentioned near-mouth filter rod, hollow filter rod and paper filter rod is an exemplary implementation, and other implementations can also be used, for example, the near-mouth filter rod, hollow filter The rod is connected to the paper filter rod, either through the cooperation of the cigarette holder filter rod glue and the tipping paper, or directly through the tipping paper for fixed connection, etc., which will not be repeated here.

One end of the filter rod is connected with a tobacco rod, and the tobacco rod contains an aerosol matrix. The aerosol matrix refers to the structure in which aerosols are generated when the user smokes. Aerosol refers to a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium, also known as a gas dispersion system. The solid or liquid small particles of the aerosol dispersion phase, usually 0.001 to 100 μm in size. While liquid aerosols are usually referred to as fog, solid aerosols are usually referred to as fog. When a user smokes, whether by directly igniting a cigarette, or by using a heat-not-burn device to smoke, the matrix made of tobacco leaves contained in the tobacco rod will generate aerosols, which can be This portion contained within the tobacco rod is referred to as the aerosol matrix.

The structure of the aerosol matrix can be varied. For example, the structure of the aerosol matrix can be in the form of filaments, that is, the tobacco is cut into shredded tobacco after drying, and then rolled from the shredded tobacco; it can also contain shredded tobacco and other substances in the interior. Of course, in order to ensure that the tobacco and other substances in the aerosol matrix will not fall into the heat-not-burn cigarette during the heating-not-burning process of the cigarette, additional steps such as compaction can be carried out during manufacture to make the structure of the aerosol matrix itself. Firmer, i.e. denser. On the outer periphery of the aerosol substrate, a forming paper is arranged to wrap the aerosol substrate, and the forming paper is used to fix the aerosol substrate inside the tobacco rod. The material of the forming paper can be sulfuric acid paper. The sulfuric acid paper has the advantages of strong toughness, high thermal conductivity, high temperature resistance, etc., and under the wrapping of the sulfuric acid paper, the internal aerosol matrix is heated evenly, which makes the user feel better when smoking. . Of course, in addition to sulfuric acid paper, the forming paper can also be made of other materials such as aluminum foil paper, which are not further limited here.

One end of the tobacco rod is connected with the filter rod, and the other end is connected with the plug. The plug can effectively prevent the substance inside the cigarette rod from falling into the smoking set when the cigarette is inserted into the smoking set. The plug can be made of the same material as the paper filter rod, which will not affect the user's smoking experience while blocking the tobacco rod. Of course, the plug can also be made of other materials, which is not limited here. Wherein, the tobacco rod and the plug can be connected and fixed by forming paper, that is, the tobacco rod and the plug can be fixed together by the forming paper. Of course, the tobacco rod and the filter rod can also be fixedly connected by forming paper. Since the outer periphery of the filter rod is wrapped with the tipping paper, when connecting the filter rod and the cigarette rod, the connecting part of the tipping paper and the forming paper can be set by overlapping wrapping, that is, the outer surface of part of the forming paper is wrapped with the tipping paper. Paper.

When a user heats a cigarette through a heat-not-burn smoking device, the heating method usually adopts sheet heating or needle heating.

When using needle heating, a needle-shaped heating body needs to be inserted into the tobacco rod to heat the aerosol matrix inside the tobacco rod. In the embodiment of the present application, if the heating body is to be inserted into the tobacco rod, it needs to pass through the plug first. At this time, the heated part includes at least two parts of the tobacco rod and the plug. When using sheet heating, a sheet-shaped heating body needs to be wrapped around the periphery of the tobacco rod to heat the tobacco rod. The portion heated at this time includes at least the tobacco rod portion.

When the sheet heating is used, the two parts of the tobacco rod and the plug can also be heated together. At this time, the existing heat-not-burn cigarettes can be used to heat the cigarettes in the embodiments of the present application, and there is no need to additionally design and produce special Smoking sets, saving costs.

To sum up, in the two commonly used heating methods, the plug will be heated more or less in the process of heating the aerosol matrix. Therefore, the material of the plug can be made of paper to prevent the heating It affects the user's smoking taste and increases the user's experience.

Since a plug is added to the cigarette, the resistance of the user during the smoking process will be increased, so a hollow filter rod is arranged in the filter rod to reduce the resistance of the user when smoking. Among them, when setting the plug, if the plug is too short, it will be easily damaged and cannot play the role of fixing the aerosol matrix; if the plug is too long, the heating needles of different types of smoking cigarettes will not burn due to the heating needle Lengths may vary and may prevent the heated needle from penetrating into the rod. Therefore, the length of the plug may vary depending on the cigarette model. This means that while increasing the length of the plug, because it increases the resistance of the user during smoking, it is necessary to reduce the length of the filter rod to keep the resistance that the user experiences during smoking basically unchanged as much as possible. . That is, the length of the plug is inversely related to the length of the filter rod. Of course, it is also possible to increase the length of the plug while increasing the length of the hollow filter rod under the condition that the overall length of the filter rod remains unchanged or reduced to maintain the resistance basically unchanged. That is, the length of the plug is positively correlated with the length of the hollow filter rod.

In one embodiment, taking into account the length of the smoking article and the smoking habits of the user, the length ratio of the filter rod to the aerosol matrix can be set in the range of 3:1 to 16:5, and the length of the aerosol matrix to the plug can be set The range of the ratio is set in 5:1 to 6:1. In the filter rod, set the range of the length ratio of the near-nose filter rod to the hollow filter rod in the range of 4:5 to 1:1, and set the length ratio of the hollow filter rod to the paper filter rod in the range of 15:2 to 9:1.

In a practical way, in order to make the cigarettes meet the smoking habits of most users, the length ratio of the filter rod, the aerosol matrix and the plug can be set to 16:5:1, and the filter rod is placed in the filter rod. The length ratio of the near-mouth filter rod, hollow filter rod and paper filter rod is set to 15:15:2.

In the actual production process, the length of the filter rod can be set to 32mm, the length of the aerosol matrix can be set to 10mm, and the length of the plug plug can be set to 2mm. In the filter rods, the length of the filter rod near the mouth end was set to 15mm, the length of the hollow filter rod was set to 15mm, and the length of the paper filter rod was set to 2mm. The cigarettes produced in this length can not only meet the requirements of most different types of heat-not-burn smoking devices, but also enable most users to have a good experience when smoking.

The above descriptions are merely one or more embodiments of the present specification, and are not intended to limit the present specification. Various modifications and variations of the one or more embodiments of this specification are possible for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of one or more embodiments of this specification should be included within the scope of the claims of this specification.
