Description

An aerosol-generating product with a composite form of blocking member

Technical field

The invention relates to the technical field of heat-not-burn cigarettes, and in particular to an aerosol-generating product with a composite sealing member.

Background technique

As consumers pay more attention to health issues and demand for personalized experiences in cigarette products, the tobacco industry continues to respond to the upgrading of consumer demands and develop various smoking products that reduce scorch and harm. Among them, heated cigarettes can provide a healthier smoking experience while meeting consumers' sensory needs for cigarette products because their cigarette heating method is different from traditional cigarette products.

Existing integrated aerosol-generating products include an outer tube, an aerosol-generating matrix filled in the outer tube, and other units for cooling and circulating aerosol. At present, the aerosol-generating matrix of integrated aerosol-generating products is usually granular aerosol-generating material. Since the bulk aerosol-generating particles cannot be fixed, they must be filled into the outer tube by filling, and the aerosol-generating particle segments have two sections. On the other hand, the particles need to be fixed by means of sealing paper and plugging parts. In order to collect aerosols and increase the amount of smoke, the downstream of the plugging part is usually a cavity (cavity section) defined by the outer tube. The cavity section The downstream is the filtration section. At present, the filling method is used to prepare the above-mentioned aerosol-generating products. The production process sequence is: seal one end of the pipe, and then fill the aerosol-generating matrix, sealing member and filter member sequentially from the other end. After filling the filter member, At the same time, reserve a distance between the cavity and the sealing member, and the outer surface of the sealing member and the filter member are not glued to the inner wall of the paper tube. After direct filling and placing it in a fixed position, the friction with the inner wall of the paper tube will pass. fixed. The problems with the above filling preparation method are: 1. When filling, the pipe is placed vertically, and the positions of the sealing members and filter members on both sides of the cavity are difficult to locate. It is easy to have inconsistent axial lengths of the cavity segments of different samples; 2. The sealing The outer surface of the plugging piece and filter piece and the inner wall of the paper tube are fixed only by friction. During transportation, the plugging piece and filter piece are easily displaced toward the cavity section, or the filter piece is partially sucked out of the outer tube during the suction process; 3. Filling This method limits it to batch filling of individual pipes, and the production efficiency is low.

In addition, existing blocking parts are usually multi-hole fastener segments (commonly known as "gear parts"). The multi-through-hole fastener segments are usually made of ceramic or silica gel, and their outer walls are firmly adhered to the paper tube through adhesives. The inner wall has at least one axial through hole in its center, and/or has at least one peripheral ventilation groove on its outer periphery. Their sizes allow smoke to pass through but do not allow aerosol source material particles to pass through, thus blocking the aerosol source. Material particles can in turn deliver aerosols. However, the existence of multi-through-hole firmware segments has brought increased costs and many operational inconveniences to the industrial manufacturing of particulate aerosol-generating products. Therefore, those skilled in the art have always hoped to eliminate the multi-through-hole firmware segments. However, after canceling the multi-through-hole firmware section, an airflow channel section must be set up downstream of the particle section to collect and accommodate aerosols, and this section can also restrain scattered aerosol source material particles. There is a dilemma, so for the design of the blocking member Also needs improvement.

Therefore, how to efficiently produce granular aerosol-generating products with a cavity structure, ensure the stability of the plugging and filtering parts without displacement, and replace the existing gear-type plugging parts with an integrated aerosol-generating product? The key problems that need to be solved in product production.

In order to solve the above problems, the present invention is proposed.

Contents of the invention

The present invention provides an aerosol-generating product with a composite blocking member, which includes an integrated outer tube 1, an aerosol-generating matrix 6 located in the outer tube 1, a blocking member 2, a cavity structure 3 and Filter 4;

The blocking member 2 includes a tube wall 21 and a tube cavity 22. The tube wall 21 is a grooved corrugated structure, which includes an outer layer 211, an inner layer 212, and a grooved corrugated layer 213 located between the two. The outer layer 211 defines the outer surface of the blocking member 2, and the inner layer 212 defines the lumen 22;

There is a gathering sheet rod 221 inside the lumen 22 . That is to say, the sealing member 2 of the present invention itself has the outer layer 211 instead of using the outer tube 1 as the outer layer.

Preferably, the gathered sheet rod 221 is made of sheet materials, and the volume of the gathered sheet rod 221 accounts for 30-80% of the volume of the tube lumen 22, that is, the sheet material is in the tube. The filling level in cavity 22 is 30-80%. The gathering here can be disordered gathering or orderly and regular gathering.

Preferably, the sheet material includes heat shrinkable materials and non-heat shrinkable materials, the heat shrinkable materials are selected from polymer materials or cellulose acetate, and the polymer materials include polylactic acid and polycarbonate; the non-heat shrinkable materials are selected from Paper;

The gathered sheet rod 221 is selected from heat shrinkable materials and can be deformed after the temperature reaches 120-180°C. More preferably, deformation occurs after the temperature reaches 120°C.

Preferably, the outer layer 211 is selected from paper; the inner layer 212 is selected from tow-shaped materials or wrinkled sheets. The tow-shaped materials include acetate fiber tows and polylactic acid tows. The wrinkled sheets include Paper material (the paper material can be coated with polymer materials), reconstituted tobacco leaves or polymer material sheets; the grooved corrugated layer 213 is selected from paper materials or non-woven fabrics with groove structures. In the actual selection process, if you need a wrinkled sheet, give priority to non-woven fabrics, and if you need a smooth sheet, give priority to paper. In addition, it is preferable that the grooved corrugated layer sheet is pre-pressed to form grooved folds, and then wrapped with the outer layer 211 and the inner layer 212 to form the tube wall of the grooved corrugated structure. When preparing the corresponding gathered sheet rod 221 in the lumen, the sheet material is first pressed to make indentations and then gathered, which facilitates the gathering process.

Preferably, the cross-sectional shape of the grooves in the grooved corrugated layer 213 is “U”-shaped or “V”-shaped.

Preferably, the grooved corrugated layer 213 also has a flavoring material layer and/or a smoking material layer, which can be selected from commonly used flavors and fragrances or smoking agents. For example, the flavoring material is selected from natural flavor raw materials, tobacco infusions, etc. ointment; the smoking substance is selected from propylene glycol and glycerol.

Preferably, the cavity structure 3 further contains functional materials; and/or the cavity structure 3 further contains an empty tube 32 . The tube wall of the hollow tube 32 is made of paper, silica gel, fiber acetate, polylactic acid, and non-woven fabric. Functional materials can be any form of substances with cooling and aroma-enhancing functions in the prior art.

Preferably, the outer tube 1 at the cavity structure 3 has a ventilation hole 31 radially penetrating the outer tube 1 . When there is an empty pipe in the cavity section 3, the vent hole 31 penetrates both the outer tube 1 and the empty pipe. The purpose of the vent 31 is to introduce air into the cavity section, on the one hand, to reduce the temperature of the aerosol, and on the other hand, to reduce the suction resistance. Therefore, whether the vent 31 is needed is determined based on the actual aerosol temperature and suction resistance. When the ventilation hole 31 needs to be provided, it is preferably punched to form the ventilation hole. Of course, it is also possible to use breathable paper as the outer tube or the empty paper tube in the cavity section without drilling, as long as air can be introduced into the cavity section. That’s it.

Preferably, there is an adhesive between the outer surface of the blocking member 2 and the inner surface of the outer tube 1, and there is an adhesive between the outer surface of the filter member 4 and the inner surface of the outer tube 1. The adhesive can be selected from ordinary joint glue.

Preferably, the outer tube 1 is a paper tube or a non-woven tube. The outer tube 1 has an anti-seepage/heat-conducting layer with an anti-seepage or heat-conducting function (especially when the outer tube 1 is a non-woven tube). The anti-seepage/heat-conducting layer includes a waterproof layer and/or an oil-proof layer and /or thermal conductive layer;

The waterproof layer uses alkyl ketene dimer AKD, cationic rosin gum or a mixture of iron-free aluminum sulfate, and paraffin materials; the oil-proof layer uses fluorocarbon organic matter, modified starch, a mixture of AKD and paraffin, and a mixture of AKD and modified starch. The thermal conductive layer is selected from but not limited to an aluminum foil layer, which is added to the inner wall of the cigarette paper tube by pasting; the aluminum foil layer can play a role in waterproofing and/or oil resistance, and at the same time, the aluminum foil layer also has a thermal conductive and thermal insulation effect. In order to make the smoking material on the inner wall of the cigarette heated evenly.

Preferably, the waterproof layer and/or oil-proof layer is coated on the inner wall of the cigarette paper tube by spraying.

During the storage of cigarettes, moisture in the smoking material seeps into the outside of the cigarette paper tube, causing yellow spots. Therefore, it is necessary to add a waterproof layer to the inner wall of the cigarette paper tube filled with smoking material. The waterproof layer is made of alkyl ketene dimer AKD, cationic rosin gum or a mixture of iron-free aluminum sulfate and paraffin materials, which can prevent moisture in the smoking material from penetrating to the outside of the cigarette paper tube.

Similarly, smoking materials, flavors and fragrances are added to the smoking materials. When left for a long time, the smoking agents in the smoking materials will carry flavors and fragrances and penetrate into the outside of the paper tube, causing yellow spots and affecting the appearance of the paper tube. Since the smoking agent is oily, it is necessary to add an oil-proof layer to the inner wall of the cigarette paper tube filled with smoking material. The oil-proof layer uses a mixture of fluorocarbon organic matter, modified starch, AKD and paraffin. The mixture of AKD and modified starch can prevent the smoking agent in the smoking material from carrying flavors and fragrances from penetrating into the outer wall of the paper tube and preventing the occurrence of yellow spots.

Preferably, the aerosol generating matrix 6 is in the form of sheets, filaments, granules, paste strips or rods with a pore structure. The paste-shaped aerosol-generating matrix includes smoke-generating agents, tobacco powder, adhesives, flavors and fragrances, PH regulators, flame retardants, etc., wherein the adhesive is selected from tapioca starch and CMC, and the PH regulator is selected from carbonates. Or citrate, more preferably selected from potassium carbonate.

Preferably, when the aerosol-generating matrix 6 is granular, there is a sealing step after step two to move the aerosol-generating matrix containing cavity 5 containing the aerosol-generating matrix 6 away from the end face of the filter section to form a sealing film 7; When the aerosol generating matrix 6 is in the form of a paste strip, the sealing step is not required, and of course there is no conflict with the sealing step. In the actual production process, it is determined whether a sealing film is needed based on the situation of the aerosol generation matrix 6.

That is to say, the mouth rod in step one can be a separate mouth rod, that is, the outer tube 1 contains a blocking member 2, a cavity section 3, a filter 4 and an aerosol-generating matrix containing cavity 5. In this case, When performing step two, it is only necessary to point the aerosol-generating matrix containing cavity 5 vertically upward. Of course, the mouth rod in step 1 can be divided into multiple mouth rods, that is, the outer tube 1 contains a blocking member 2, a cavity section 3, a filter 4 and an aerosol generating matrix containing cavity 5, and multiple mouth rods It is connected through the filter element 4 and/or the aerosol-generating matrix accommodation cavity 5. The connection point has twice the axial length of the filter element 4 or the aerosol-generating matrix accommodation cavity 5. In this case, when proceeding to step two, it is necessary to separate it first. Cut the mouth rod strip into multiple mouth rods, and then place the aerosol-generating matrix containing cavity 5 vertically upward. That is to say, the axial length of the filter element at the connection point is twice the axial length of the filter element in a single nozzle rod. Similarly, the axial length of the aerosol-generating matrix accommodation cavity reserved at the connection point is equal to the axial length of the single nozzle rod. The aerosol-generating matrix contains twice the axial length of the cavity. So that after being cut, each mouth rod has a complete filter element and an aerosol-generating matrix containing cavity.

In the second preparation method above:

In step two, the flowable aerosol-generating material can be loaded into the aerosol-generating matrix containing cavity 5 by any method, such as squeezing;

The preparation of the nozzle bar in step one can be in a horizontal state, a vertical state, or any state in between, as long as the nozzle bar is in a vertical state when filling the aerosol-generating material in step two. , which facilitates the quantitative extrusion of flowing aerosol-generating materials.

The purpose of inverting and placing it on a flat surface and drying and expanding it at a certain temperature is to make the end face of the aerosol generating rod 6 away from the filter element flush.

Preferably, in step one, the mouth rod strip can be divided into multiple mouth rods, and the multiple mouth rods are connected through the filter member 4 and/or the aerosol generating matrix containing cavity 5; at this time, between step one and step two There is also a cutting step of cutting at the connected filter element 4 and/or the connected aerosol-generating matrix containing cavity 5 to cut the mouth rod strip into multiple mouth rods.

Preferably, in step two, the fluid aerosol-generating material includes smoking raw materials, smoking aids and solvents. The smoking raw materials are crushed in advance and then passed through a 40-200 mesh sieve, and then the sieved smoking raw materials are separated into Mix it with smoking aids and solvents in a certain proportion and then blend into a fluid aerosol-generating material, similar to the state of paste;

Preferably, in step two, the filling amount of the flowing aerosol-generating material is 50-95% of the volume of the aerosol-generating matrix containing cavity 5 . More preferably 90%.

Preferably, in step two, the fluid aerosol-generating material also contains a binder, and the fluid aerosol-generating material uses its own binder to bond to the inner wall of the outer tube 1 during the drying and expansion process. The binder is selected from chitosan, hydroxyethylated composite modified ethyl cellulose, guar gum, carboxymethyl cellulose, starch, modified starch, plant cellulose, microcrystalline cellulose, Hydroxyethyl cellulose, hydroxyethyl methyl cellulose.

Preferably, in step two, the flowing aerosol-generating material is squeezed into the aerosol-generating matrix containing cavity 5 against the inner surface of the outer tube 1, and the squeezed-in flowing aerosol-generating material forms a central cavity, The center is the volume reserved for expansion of the aerosol-generating material; or,

The flowing aerosol-generating material is loaded into the aerosol-generating matrix containing cavity 5 in two parts, wherein the first part of the aerosol-generating material is squeezed into the aerosol-generating matrix containing cavity 5 against the inner surface of the outer tube 1 , the first part of the aerosol-generating material squeezed in forms a central cavity, and the second part of the aerosol-generating material is squeezed into the central cavity, between the first part of the aerosol-generating material and the second part of the aerosol-generating material There is a gap, which is the volume reserved for expansion of the aerosol-generating material.

Preferably, there is a sealing step after step two to form a sealing film on the aerosol-generating matrix containing cavity 5 containing the aerosol-generating matrix 6 away from the end surface of the filter section. In the actual production process, it is determined whether a sealing film is needed based on the situation of the aerosol generation matrix 6.

Preferably, the drying temperature in step three depends on the solvent in the aerosol-generating material. When the solvent is ethanol, the drying temperature is 50-60°C and the drying time is 0.5-1h; when the solvent is water, the drying temperature is 60°C. -70℃, drying time is 1-2h.

Compared with the existing technology, the present invention has the following beneficial effects:

1. The axial cavity formed by the grooved corrugated tube wall on the outer layer of the sealing member of the present invention can be used as an air flow channel for aerosol to circulate. Furthermore, the grooved corrugated layer 213 also has an aromatic material layer and/or Or a smoke-generating material layer, which can further incense the passing aerosol and increase the amount of smoke. The multi-layered grooved corrugated layers support each other, which can reserve as many airflow channels as possible while ensuring the blocking of aerosol-generating materials. For the first time, the present invention eliminates multi-hole fastener segments and combines grooved corrugated components with bulk aerosol source material particles. Moreover, due to the tube wall of the grooved corrugated structure and the blocking structure in the tube cavity, it can act as a constraint. The effect of aerosol source material particles eliminates the need for multi-via fasteners.

2. There is a gathered sheet rod 221 in the lumen of the blocking member of the present invention. The volume of the gathered sheet rod 221 accounts for 30-80% of the volume of the lumen 22. The gathered sheet can realize granular, etc. Block aerosol-generating materials while reserving as many airflow channels as possible. Furthermore, the gathered sheets divide the central cavity into numerous airflow channels, which can disperse aerosols, and the contact area between the sheets and aerosols is large, which is more conducive to reducing the temperature of the aerosols. This structure can simultaneously ensure the three effects of blocking, cooling and suction resistance. More importantly, the volume of the gathered sheet rod 221 of the present invention accounts for 30-80% of the volume of the lumen 22 (before suction). When this filling amount is exceeded, the suction resistance will increase significantly, and When the filling amount is less than this, it is difficult to block the aerosol-generating material and reduce the temperature of the aerosol.

3. In the preferred embodiment of the present invention, the gathered sheet rod 221 can deform after the temperature reaches 120°C. That is to say, during the suction process, the gathered sheet rods shrink after being heated and block part of the intermediate airflow. During the suction process, the diameter of the airflow channel is changed, which allows more aerosols to go into the grooved corrugated structure of the tube wall. , and the grooved corrugated layer 213 also has a flavoring material layer and/or a smoking material layer, so that more aerosols can come into contact with the flavoring material and/or smoking material, thereby further improving the aerosol flavoring and flavoring. The effect of large smoke volume.

Regarding the preparation method:

4. In the present invention, the remaining units except for the aerosol-generating particle segment are first formed by rolling and compounding. During compounding, a cavity for filling the aerosol-generating material is reserved. After compounding, the parts are cut as needed, and then the parts are cut. The last mouth rod with the aerosol-generating matrix holding chamber 5 is placed vertically, and then the aerosol-generating material is filled into the aerosol-generating matrix holding chamber 5. Since the blocking member 2 and the filtering member 4 are both made of composite rolls, molding method, so the blocking member 2 and the filter member 4 are easier to position in the axial position, which can better ensure the consistency of the axial length of the cavity segments 3 of different samples.

5. Since both the plugging member 2 and the filtering member 4 are formed by a composite rolling method, the adhesive can be applied more conveniently between the outer surfaces of the plugging member 2 and the filtering member 4 and the inner surface of the paper tube, thereby ensuring that There will be no displacement at either end during suction or transportation.

6. The present invention uses the method of first compounding and then filling to prepare aerosol-generating products. Multiple nozzle rods can be compounded at the same time, and then cut and then filled with aerosol-generating materials. Since except for the aerosol-generating materials, the other units are Through the composite form, the efficiency of each unit is greatly improved compared to filling each unit individually.

7. The present invention fills the flowing aerosol-generating material by extrusion, and then makes the aerosol-generating matrix containing cavity 5 face vertically downward, places it on a flat surface, and dries and expands at a certain temperature, so that the aerosol-generating material solidifies to form an aerosol-generating material. The fixed aerosol-generating rod 6 in the aerosol-generating matrix accommodation cavity 5 can be produced more efficiently by extrusion, and the aerosol-generating rod 6 obtained after drying and expansion has a pore structure, which is beneficial to the aerosol generation. Release and circulation. The purpose of inverting and placing it on a flat surface and drying and expanding it at a certain temperature is to make the end face of the aerosol generating rod 6 away from the filter element flush.

More preferably, deformation occurs after the temperature reaches 120°C. That is to say, the sealing member 2 of the present invention itself has the outer layer 211 instead of using the outer tube 1 as the outer layer.

The gathered sheet rods 221 are made of heat shrinkable materials. The heat shrink material is selected from polylactic acid. The volume of the gathered sheet rod 221 accounts for 45% of the volume of the lumen 22 , that is, the filling amount of the polylactic acid sheet in the lumen 22 is 45%.

The outer layer 211 is selected from paper materials; the inner layer 212 is selected from paper materials; the grooved corrugated layer 213 is selected from non-woven fabrics with groove structures; and the spacer layer 221 is selected from non-woven fabrics.

The cross-sectional shape of the grooves in the grooved corrugated layer 213 is “V” shaped.

The grooved corrugated layer 213 also has a flavoring material layer and a smoking material layer.

Example 2

This embodiment prepares a multi-stage aerosol-generating product according to preparation method 2. The difference between this embodiment and Example 1 is: 1. In step 1, the mouth rod strip can be cut into 4 mouth rods, and the 4 mouth rods pass through The filter element 4 is connected to the aerosol-generating matrix containing cavity 5; at this time, there is also a cutting step between step one and step two, where the connected filter element 4 and the connected aerosol-generating matrix containing cavity 5 are cut to separate the mouth. Cut the stick into 4 mouth sticks. The axial length of the filter element at the connection point is twice the axial length of the filter element in a single nozzle rod. Similarly, the axial length of the aerosol generation matrix containing cavity reserved at the connection point is equal to the aerosol generation in a single nozzle rod. The matrix contains twice the axial length of the cavity. So that after being cut, each mouth rod has a complete filter element and an aerosol-generating matrix containing cavity. 2. In step 2, the flowing aerosol-generating material is loaded into the aerosol-generating matrix containing cavity 5 in two parts, wherein the first part of the aerosol-generating material is squeezed into the aerosol against the inner surface of the outer tube 1 In the generation matrix containing cavity 5, the first part of the aerosol-generating material squeezed in forms a central cavity, and the second part of the aerosol-generating material is squeezed into the central cavity. The first part of the aerosol-generating material and the second part There is a gap between the aerosol-generating materials, and the gap is the volume reserved for expansion of the aerosol-generating material.

Example 3

In this embodiment, a multi-stage aerosol-generating product is prepared according to the preparation method 1. The structure of the blocking member in the aerosol-generating product is the same as in Example 1, which includes the following steps:

Step 1: Preparation of mouth sticks:

Step 2, filling of aerosol generating matrix 6:

Put the mouth rod in an upright state, that is, perpendicular to the horizontal plane, with the aerosol-generating matrix holding chamber 5 facing upwards. Put the aerosol-generating matrix 6 into the aerosol-generating matrix holding chamber 5 by filling. .

In step 1, the mouth bar is prepared in a horizontal state.

In step two, the aerosol generating matrix 6 is in the form of granules. When the aerosol-generating matrix 6 is granular, there is a sealing step after step two to move the aerosol-generating matrix containing cavity 5 containing the aerosol-generating matrix 6 away from the end surface of the filter section to form a sealing film 7 .

The outer tube 1 is a paper tube.

Example 4

In this embodiment, a multi-stage aerosol generating product is prepared according to the preparation method 1. The difference between this embodiment and Example 3 is: 1. In step 1, the mouth rod strip can be cut into 4 mouth rods, and the 4 mouth rods pass through The filter element 4 is connected to the aerosol-generating matrix containing cavity 5; at this time, there is also a cutting step between step one and step two, where the connected filter element 4 and the connected aerosol-generating matrix containing cavity 5 are cut to separate the mouth. Cut the stick into 4 mouth sticks. The axial length of the filter element at the connection point is twice the axial length of the filter element in a single nozzle rod. Similarly, the axial length of the aerosol generation matrix containing cavity reserved at the connection point is equal to the aerosol generation in a single nozzle rod. The matrix contains twice the axial length of the cavity. So that after being cut, each mouth rod has a complete filter element and an aerosol-generating matrix containing cavity. 2. In step two, the aerosol generating matrix 6 is in the shape of a paste strip. When the aerosol generating matrix 6 is in the form of a paste strip, the sealing step is not required.

Example 5

The only difference between this embodiment and Embodiment 1 is that the volume of the gathered sheet rod 221 in this embodiment accounts for 90% of the volume of the lumen 22 , that is, the volume of the polylactic acid sheet in the lumen 22 Fill level is 90%.

The aerosol-generating products prepared in Example 1 and Example 5 were subjected to sensory evaluation, and the scores are shown in Table 1.

Mainly based on Q/YNZY.J07.022.

Table 1 Sensory evaluation scores of different aerosol-generating product samples when inhaled

It can be seen from Table 1 that the difference between the aerosol-generating product of Example 1 and the aerosol-generating product of Example 5 is not very obvious in terms of aroma, fragrance, irritation improvement, strength, coordination, and taste. However, the aerosol-generating product of Example 5 The amount of smoke produced by the aerosol-generating product during the suction process is much smaller than that of the aerosol-generating product of Example 1. The reason for this phenomenon is that the volume of the gathered sheet rod 221 in Example 5 accounts for 90% of the volume of the tube cavity 22 , that is to say, the volume of the air flow channel accounts for 10% before suction, but during the suction process, the gathered sheet rod 221 is heated and deformed, blocking most of the air flow channels, and the aerosol can only pass through the groove corrugations of the tube wall. , so the amount of smoke is significantly reduced, and the smaller amount of smoke will lead to relatively poor aroma, fragrance, irritation, strength, coordination, and taste. In addition, during the puffing process, sensory evaluation experts also clearly felt that the puffing resistance of the aerosol-generating product of Example 5 was very large and the puffing feeling was poor. Therefore, during the actual suction process, the gathered sheet rods 221 are heated and deformed to appropriately block part of the central airflow channel, thereby allowing the aerosol to pass through the grooved corrugated layer, which is beneficial to improving the flavoring effect, but will also lead to a reduction in the airflow channel, so In order to simultaneously take into account the effects of smoke volume and aroma enhancement, the volume of the gathered sheet rod 221 in the present invention accounts for 30-80% of the volume of the tube cavity 22 .
