Embodiment one

Please refer to Figure 1 and Figure 2 together. This embodiment provides a cigarette stick 100 for a heat-not-burn cigarette, which is specifically applied to a center-heated heat-not-burn cigarette.

The tobacco stick 100 of the heat-not-burn cigarette includes a filter rod segment 10 and a tobacco segment 20 , and the tobacco segment 20 is connected to one end of the filter rod segment 10 . Wherein, the tobacco segment 20 refers to the part containing tobacco substances. When the cigarette stick 100 of the heat-not-burn cigarette is used, the tobacco segment 20 needs to be inserted into the heating chamber 210 of the smoking device 200 of the heat-not-burn cigarette correspondingly. , used to be in contact with the heating element 220 of the smoking appliance 200 for heat-not-burn cigarettes.

It should be noted that the connection of the tobacco segment 20 to one end of the filter rod segment 10 refers to: the tobacco segment 20 can be directly connected to one end of the filter rod segment 10; or, the tobacco segment 20 can be Indirectly connected to one end of the filter rod segment 10, that is, a corresponding rod structure can also be provided between the tobacco segment 20 and the filter rod segment 10, such as between the tobacco segment 20 and the filter rod segment 10 Arbitrary functional rod structures such as support sections and cooling sections can also be arranged between them.

The tobacco segment 20 includes wrapping paper 21 and tobacco substance 22 , the wrapping paper 21 surrounds and forms a containing space 211 , and the tobacco substance 22 is filled in the containing space 211 . And the wrapping paper 21 is provided with a through hole 212 , and the through hole 212 is arranged through the wrapping paper 21 along the radial direction of the tobacco segment 20 .

It can be understood that heat-not-burn cigarettes are a new type of tobacco product that uses different methods such as electric energy to generate heat sources to heat tobacco substances, and then produce aerosols containing nicotine. The mainstream heat-not-burn cigarettes in the market are mainly center-heated (such as IQOS). The center-heated heat-not-burn cigarettes refer to: the heating element is set When a cigarette branch is inserted into the heating chamber, the heating element is correspondingly inserted into the tobacco section of the cigarette branch of the heat-not-burn cigarette, so that the tobacco substance in the tobacco section is heated by the heating element. Represented by IQOS, electric heating is adopted, and the sheet heating element heats the tobacco segment inserted into the cigarette of the heat-not-burn cigarette to generate aerosol. The tobacco section of the cigarette of the heat-not-burn cigarette matched with IQOS generally needs to arrange the tobacco material evenly and orderly (along the radial direction of the cigarette), otherwise, after inserting the cigarette, due to the extrusion of the heating element, the resistance of the tobacco section is relatively high. Large, resulting in large draw resistance, small smoke in the first two puffs, etc., which affects the smoking experience. In particular, relatively disordered tobacco sections such as mixed shreds are used in the cigarettes of heat-not-burn cigarettes, and the filling density of shredded tobacco in such tobacco sections is relatively high. Due to the high packing density of shredded tobacco, after inserting a sheet or rod-shaped heating element, it is more likely to cause tobacco segment extrusion, large suction resistance, insufficient mixing and condensation of air and atomizer, and poor smoking experience such as small smoke volume.

In the cigarette 100 of the heat-not-burn cigarette provided in this embodiment, a perforated design is added on the surface of the tobacco section 20, which can increase the ventilation of the tobacco section 20 and improve the insertion and heating of the tobacco section 20. Ventilation performance behind the cavity. Therefore, after inserting the heating element, due to the extrusion of the heating element, the suction resistance is relatively large, and the smoke in the first few puffs is small, which affects the smoking experience. It also improves the matching performance of different tobacco segments (different shredded tobacco arrangements, disordered, relatively orderly) and cigarette sticks of heat-not-burn cigarettes, so that the cigarette sticks 100 of heat-not-burn cigarettes can be better compatible with different types Smoking apparatus for heat-not-burn cigarettes.

It can be understood that although the cigarettes of the prior art have a perforated and ventilated structure, such as: in traditional cigarettes, holes are mainly punched on the tipping paper to increase ventilation dilution, reduce draw resistance, and reduce tar. In the cigarettes of heat-not-burn cigarettes, holes are mainly punched in non-tobacco sections such as filter rod sections, so as to achieve effects such as reducing draw resistance and cooling. However, in the prior art, there is no perforation on the wrapping material, especially the structure of perforation on the tobacco section of the cigarette of the heat-not-burn cigarette.

In this embodiment, the through hole 212 is opened on the wrapping paper 21 of the tobacco segment 20, which solves the problem of extruding the tobacco material due to the insertion of the heating element, increasing the packing density of the tobacco segment, The technical problem that leads to small smoke in the first few puffs of the smoke better improves the puffing experience of the heat-not-burn cigarette 100 in the first few puffs. Moreover, only opening holes in the wrapping paper 21 will not affect the normal function of the tobacco segment 20 and will not adversely affect the cigarette stick 100 of the heat-not-burn cigarette.

It can be understood that by opening different numbers of the through holes 212 at different positions on the tobacco segment 20 , the ventilation performance of the cigarette stick 100 of the heat-not-burn cigarette inserted into the heating element can be correspondingly improved.

Through this structure, the ventilation volume along the axial direction of the tobacco segment 20 is better increased, and the ventilation volume of each part along the axial direction is more balanced, which further guarantees the puffing experience of the first few puffs.

Preferably, in this embodiment, a plurality of (at least two) through-holes 212 are opened, and the plurality of through-holes 212 are distributed sequentially along the circumference of the tobacco segment 20, and two adjacent ones The circumferential distances between the through holes 212 are equal. That is, a plurality of through holes 212 are evenly spaced along the circumference of the tobacco segment 20 . Through this structure, the ventilation volume along the circumferential direction of the tobacco segment 20 is better increased, and the ventilation volume of each part along the circumferential direction is more balanced, which further guarantees the puffing experience of the first few puffs.

Of course, in other embodiments, multiple sets of the through holes 212 may also be provided, and multiple sets of the through holes 212 are evenly distributed along the axial direction of the tobacco segment 20 . And each group of the through holes 212 includes a plurality of through holes, and the plurality of through holes in each group are evenly spaced along the circumference of the tobacco segment 20 . That is to say, in other embodiments, the through holes 212 can be provided along the axial and circumferential directions of the tobacco segment 20 , so that the air flow can be further increased.

The wrapping paper 21 can be made of perforated cigarette paper, composite aluminum foil paper and other materials. In this embodiment, preferably, the wrapping paper 21 is ordinary cigarette paper (specifically, it can be made of natural fibers such as hemp pulp or mixed with wood pulp and fillers such as calcium carbonate) or aluminum foil rolling paper, so as to ensure the On the premise of the wrapping effect of the wrapping paper 21, the cost is also reduced as much as possible.

Preferably, the through holes 212 are formed by laser drilling or mechanical drilling. Wherein, the through hole 212 may be formed by laser drilling or mechanical drilling during the production process of the wrapping paper 21, or the through hole may be formed during the wrapping paper 21 production process of cigarettes. It is made by laser drilling or mechanical drilling. Specifically, the laser drilling is a laser drilling device, and the through hole 212 is formed on the wrapping paper 21 by the laser drilling device. The mechanical punching can specifically form the through holes 212 on the wrapping paper 21 by means of needle punching or the like.

It can be understood that the through hole 212 may be composed of a plurality of through hole units connected to each other. A through-hole unit that communicates with each other, so that a through-hole 212 is formed by a plurality of through-hole units, so that the ventilation area of the through-hole 212 can be better, and the ventilation of a single through-hole 212 is better guaranteed. quantity. In addition, a plurality of through-hole units are connected to each other to form one through-hole 212, so that the whole through-hole 212 can present a similar elongated structure, which better ensures the appearance of the cigarette 100 of the heat-not-burn cigarette sex.

Preferably, the tobacco substance 22 is loaded with an aerosol, so that the smoking experience of the smoker can be better improved. Specifically, any one or both of propylene glycol and glycerin can be used as the atomizer. Specifically, the tobacco segment 20 can be processed in a traditional cigarette process, that is, one or more tobacco shreds and sheets containing an atomizing agent are uniformly mixed; and it can be compounded with a certain functional structure, It is processed by rubbing and other processes. Wherein, the functional structure may be a flavor substance, wherein the flavor substance may be a floral, fruity, wine or tobacco flavor substance. Such as: the floral flavor substance can be the floral flavor substance of rose, gardenia or lavender; the fruity flavor substance can be the fruity flavor substance of passion fruit, pineapple or cantaloupe; the wine flavor substance can be the sauce-flavored liquor, whiskey or The aroma and flavor of sake; the aroma of tobacco can be yunyan absolute, yunyan extract or burley extract. The addition of flavor substances can enrich the mouthfeel of the mist, thereby enriching the smoking experience of the smoker.

Preferably, the through hole 212 is opened at an end of the wrapping paper 21 away from the filter rod segment 10 . Therefore, when the cigarette branch 100 of the heat-not-burn cigarette is inserted into the heating chamber and the heating element 220 is inserted into the tobacco segment 20, it can better ensure that the through hole 212 is located in the area where the heating element 220 is located. Among them, the ventilation volume of the corresponding area is better guaranteed, and the suction experience of the first few puffs is further guaranteed.

It can be understood that the perforation size and the perforation quantity of the through hole 212 can be optimally selected according to the insertion condition of the heating element. Specifically, it can measure the filling value or filling density (g/cm3) of shredded tobacco, measure the volume of the heating element (cm3), the draw resistance of the cigarette (pa), calculate the volume change rate (ΔV) before and after insertion, and design the punching size and punching hole in turn quantity. Holes are evenly distributed in the tobacco segment 20 or distributed in the tobacco segment 20 according to the factors affecting the draw resistance, and the overall draw resistance of the cigarette 100 of the heat-not-burn cigarette after perforation can be increased by testing, and then the optimized design can be completed .

The cigarette stick 100 of the heat-not-burn cigarette provided in this embodiment is perforated in the tobacco section 20 by a relatively simple and mature method such as punching, so as to increase the permeability. After pressing the tobacco substance 22, the problem of large draw resistance and poor ventilation is caused; on the other hand, after the perforation is added, after the cigarette is inserted into the smoking set, in a relatively closed environment of the smoking set, the atomized tobacco substance has more airflow after being heated. The passage produces atomized smoke, which increases the amount of smoke produced.

Moreover, the heat-not-burn cigarette stick 100 provided in this embodiment can be better compatible with cigarette sticks with different arrangements of tobacco shreds and smoking utensils with different shapes of heating elements (sheet type, rod shape), and improve consumption experience.

It can be understood that when smoking, because the tobacco segment 20 is in a relatively closed heating chamber, drilling holes in this part can reduce the temperature of the flue gas to a certain extent, and at the same time avoid the smoke caused by the perforation and cooling of the filter rod segment. Gas dilution, smoke smaller and other negative effects. The cigarette stick 100 of the heat-not-burn cigarette provided in this embodiment does not have high requirements for the improvement of the existing technology and materials, and the effect is remarkable. At the same time, it can reduce the temperature of the smoke to a certain extent, and avoid the negative effects of opening holes in the filter rod section as much as possible. Influence.
