The invention provides a cigarette for heating cigarettes, wherein the diameter of the cigarette is 5-7mm, and air holes are formed in the cigarette and penetrate through the cigarette along the radial direction of the cigarette; the air holes are formed by air hole units, at least one air hole is a composite air hole, and the composite air hole is formed by overlapping at least two air hole units. Because at least one of the air holes arranged on the cigarette of the heating cigarette is the composite air hole, and the composite air hole is formed by partially overlapping two air hole units, so that the pore volume of a single air hole is increased, more cold air can be introduced into the single air hole, the cooling effect of the single air hole is increased, the number of the air holes required to be arranged on the cigarette of the heating cigarette is smaller, the influence of the air holes on the strength of the cigarette of the heating cigarette is avoided as much as possible, the cigarette of the heating cigarette is not easy to be stressed and broken in the use process, and the normal smoking of the cigarette of the heating cigarette is ensured.
Please refer to fig. 1 in combination. The embodiment provides a cigarette 100 for heating cigarettes, wherein the diameter of the cigarette 100 is between 5 mm and 7 mm.
The cigarette 100 is provided with an air hole 10, and the air hole 10 penetrates through the cigarette 100 along the radial direction of the cigarette 100. The air holes 10 are formed by air hole units 20, at least one air hole 10 is a composite air hole 30, and the composite air hole 30 is formed by overlapping at least two air hole units 20. Wherein partial overlap refers to: the two air hole units 20 are communicated with each other, and the two air hole units 20 do not completely coincide. So that the volume of the composite air hole 30 is larger than that of the single air hole unit 20, and the space required by the composite air hole 30 in the cigarette 100 is smaller than that of the two air hole units 20.
That is, at least one air hole 10 is formed in the cigarette 100, and at least one air hole 10 among the formed air holes 10 is the composite air hole 30. Because the composite air hole 30 is formed by at least two air hole units 20, the number of the air holes 10 required to be formed in the cigarette 100 can be smaller, so that the influence of the air holes 10 on the structural strength of the cigarette 100 can be avoided as much as possible on the premise of guaranteeing the cooling effect, the cigarette 100 is not easy to be broken by stress in the use process, and the normal product suction of the cigarette 100 is better guaranteed.
It is understood that the size of the overlapping area between the two air hole units 20 in the composite air hole 30 may affect the ventilation effect of the composite air hole 30. When the overlapping area between the two air hole units 20 is small as shown in fig. 2, the ventilation area of the composite air hole 30 is relatively large. When the overlapping area between the two air hole units 20 is large as shown in fig. 3, the ventilation area of the composite air hole 30 is relatively small. The number of the air hole units 20 included in the composite air hole 30 as shown in fig. 4 can also affect the ventilation area of the composite air hole 30. Thus, the composite air holes 30 may be appropriately adjusted according to the actually required ventilation rate, such as adjusting the size of the overlapping area between the air hole units 20, the number of the air hole units 20, etc.
It can be understood that in the field of heating cigarettes, although the temperature of smoke generated by cigarettes for heating cigarettes is lower than that of traditional cigarettes, the smoke channel is shorter because of higher water content of the smoke, and the sensory temperature of main stream smoke reaching the oral cavity is higher than that of traditional cigarettes, so that the cigarettes for heating cigarettes need to have the function of cooling the smoke. At present, air holes are formed in cigarettes for heating cigarettes, so that cold air is introduced through the air holes to cool the smoke. The cigarettes heated by the heating device can be generally divided into cigarettes with diameters larger than 7mm and cigarettes with diameters between 5 and 7mm according to different diameter specifications. The cigarette with the diameter of 5-7mm has higher atomized smoke temperature, and the temperature reduction operation space of the structure or the material used in the filter stick is too small, so that the prior art generally adopts an on-line punching mode to introduce external cold air and high-temperature smoke temperature. Meanwhile, the temperature-reducing pressure of the cigarettes with the diameters of 5-7mm is higher, the number of holes in the filter stick is generally far more than that of the cigarettes with the diameters of more than 7mm (often more than 10 and 15), and the cigarettes are easily broken due to the excessive number of holes and the too small circumference in the use process.
Meanwhile, the applicant researches find that as the atomized smoke of the cigarettes with the diameter of 5-7mm mostly uses peripheral heating (inner core), the smoke temperature at the same axial position in the filter stick is high and low, the introduction of perforation is easier to mix gaseous moisture, glycerol and external cold air in a high temperature difference manner, nucleation and atomization are promoted, so that the perforation in a certain interval on the filter stick also has the effect of improving the smoke concentration.
In the cigarette 100 provided in this embodiment, the composite air holes 30 are formed in the cigarette 100, so that the pore volume of a single air hole can be increased, and more cold air can be introduced into the single air hole, so that the flue gas temperature and the concentration can be better adjusted, and the total amount of the air holes 10 required to be formed in the cigarette 100 is smaller, so that the influence of the formed air holes 10 on the structural strength of the cigarette 100 is avoided as much as possible, the cigarette 100 is not easy to be broken by stress in the use process, and the normal product suction of the cigarette 100 is better ensured.
It should be noted that, in the prior art, the punching of the cigarettes is performed by using a laser punching device, and the laser punching device can only form an air hole unit on the cigarettes at a time. Specifically, with the current cigarette punching technology, only one small round hole can be formed on a cigarette at a time. That is, in this embodiment, the air hole unit 20 is a circular hole.
For example: in the prior art, if 10 air holes are required to be formed in a cigarette, 10 air hole units which are spaced from each other are formed in the cigarette through laser drilling equipment, and one air hole unit forms one air hole, so that 10 air holes are formed in the cigarette.
In the present embodiment, since at least one of the air holes 10 is the composite air hole 30, the total amount of the air holes 10 required to be opened in the cigarette 100 may be smaller than 10 air holes. For example: when one of the air holes 10 provided on the cigarette 100 is the composite air hole 30 and the composite air hole 30 is formed by two air hole units 20, the total number of the air holes 10 required to be opened on the cigarette 100 may be 9. Of the 9 air holes 10, 1 is the composite air hole 30, and the other 8 is the common air hole 10, and the common air hole 10 is composed of one air hole unit 20. When the composite air hole 30 is formed by three or more air hole units 20, the total amount of the air holes 10 to be opened on the cigarette 100 may be smaller. Similarly, when the number of the composite air holes 30 is larger, the total amount of the air holes 10 required to be opened on the cigarette 100 can be reduced, for example: when all the air holes 10 formed in the cigarette 100 are the composite air holes 30, the total amount of the air holes 10 required to be formed in the cigarette 100 can be further reduced. It should be noted that, the number of the air holes 10 and the number of the composite air holes 30 are merely examples, and the number of the air holes 10 and the types of the air holes 10 on the cigarette 100 may be selected according to actual requirements, and only the composite air holes 30 are required to be provided, so that the temperature and the concentration of the smoke can be better adjusted, the structural strength of the cigarette 100 is better ensured, and the cigarette 100 is not easy to be broken by stress.
Preferably, a plurality of air holes 10 are formed in the cigarette 100, and all the air holes 10 formed in the cigarette 100 are the composite air holes 30. Thereby better guaranteeing the cooling effect of the single air holes 10 arranged on the cigarette 100, and also enabling fewer air holes 10 to be arranged on the cigarette 100.
Preferably, the shape and structure of the composite air holes 30 at the front part and the shape and structure of the composite air holes 30 at the tail part are the same along the punching direction of the composite air holes 30 on the cigarette 100, and the shape and structure of the composite air holes 30 between the composite air holes 30 at the front part and the composite air holes 30 at the tail part are the same. That is, in the direction of opening the plurality of composite air holes 30 on the cigarette 100 (in this embodiment, the holes are sequentially opened along the circumferential direction of the cigarette 100), the shape structure of the first opened composite air hole 30 is the same as the shape structure of the last opened composite air hole 30 when punching. That is, in one embodiment, the number of the composite air holes 30 is not less than 3, the number of the air hole units 20 included in the two composite air holes 30 located at the head and the tail is the same, and the overlapping portions of the air hole units 20 in each composite air hole 30 are the same, so that all the composite air holes 30 formed on the cigarette 100 are the same structural shape. All other composite air holes 30 located between the composite air holes 30 at the front and rear are identical in shape and structure. For example, when 4 composite air holes 30 are formed in the cigarette 100, two of the composite air holes 30 located at the front and the rear have the same shape and structure, and the other two of the composite air holes 30 have the same shape and structure, so that the ventilation rate balance of each air hole 10 can be better ensured. In other embodiments, when only two composite air holes 30 are formed, that is, only the composite air holes 30 at the head and tail are included, the shape and structure of the two composite air holes 30 may be the same.
Preferably, all the air holes 10 are equally spaced along the circumference of the cigarette 100. Namely, the air holes 10 formed in the cigarette 100 are sequentially distributed at intervals along the circumferential direction of the cigarette 100, and the intervals between two adjacent air holes 10 are equal along the circumferential direction of the cigarette 100, so that the flue gas temperature and the flue gas concentration of the cigarette 100 are better adjusted.
Preferably, the centers of all the air hole units 20 are located on the same plane, and the plane is perpendicular to the axis of the cigarette 100. That is, in this embodiment, all the air holes 10 are located at the same axial position on the cigarette 100, and the air hole units 20 in the composite air hole 30 are arranged to extend in the circumferential direction of the cigarette 100, so that the center of each air hole unit 20 is located at the same axial position on the cigarette 100. That is, in this embodiment, all the air holes 10 are annularly distributed on the cigarette 100, so that the effect of the air holes 10 on the temperature and the concentration of the smoke of the cigarette 100 is further ensured. In this embodiment, a group of the air holes 10 is provided on the cigarette 100, and all the air holes 10 in the group of air holes 10 are distributed at the same axial position on the cigarette 100. Of course, in other embodiments, more groups of the air holes 10 may be provided on the cigarette 100, for example, two groups of the air holes 10 may be provided, the air holes 10 in the same group of air holes 10 are all in the same axial position, and the two groups of air holes 10 are spaced apart from each other along the axial direction of the cigarette 100. That is, in this embodiment, the number of rows of perforations on the cigarette 100 is a single row. In other embodiments, the number of rows of perforations on the cigarette 100 may be two or more.
Preferably, in one embodiment, the diameter of the cigarette 100 is 6-7mm, and the number of the air holes 10 formed on the cigarette 100 is not more than 8, so that the structural strength of the cigarette 100 is better ensured.
Preferably, in one embodiment, the diameter of the cigarette 100 is 5-6mm, and the number of the air holes 10 formed on the cigarette 100 is not more than 6, so that the structural strength of the cigarette 100 is better ensured.
Preferably, the cigarette 100 includes a tobacco segment 40 and a filter rod segment 50 connected to the tobacco segment 40, and the air hole 10 is opened in the filter rod segment 50. The tobacco segment 40 refers to a part coated with a sheet or tobacco material, when the heated cigarette is used, the tobacco segment 40 is correspondingly inserted into a heating cavity of a heating smoking set, and the filter rod segment 50 is a part of the cigarette 100 which is not covered by the heating cavity after being inserted into the heating smoking set. In particular, the filter rod segment 50 includes, but is not limited to, a paper tube segment, a hollow acetate segment therein. Thus, the air holes 10 formed in the cigarette 100 do not affect the normal smoking of the cigarette 100.
The cigarette 100 of the heating cigarette provided in this embodiment partially overlaps a plurality of the air hole units 20 to form a strip-shaped duct (i.e. the composite air hole 30), and then uniformly distributes the plurality of strip-shaped ducts to the whole circumference of the cigarette 100 at intervals, thereby not only efficiently utilizing the circumference of the cigarette and preventing the breakage of the cigarette, but also being more beneficial to improving the punching stability of the cigarette due to the appearance of the large-area strip-shaped duct. Through the combination of punching parameters, the ventilation rate of the cigarettes can be effectively adjusted while the punching of the strip-shaped pore canals of the cigarettes is completed, so that the temperature and the concentration of the smoke of the heated cigarettes are further regulated and controlled.
Meanwhile, the embodiment also provides a method for punching the cigarette 100 for heating the cigarettes, which comprises the following steps:
s1, providing a cigarette for heating cigarettes, wherein the diameter of the cigarette is 5-7 mm;
s2, determining parameters of air holes required to be opened on the cigarettes;
s3, according to the air hole parameters determined in the step S2, opening the air holes of the cigarette along the radial direction of the cigarette, wherein the air holes are formed by air hole units, at least one air hole is a composite air hole, and the composite air hole is formed by overlapping at least two air hole units.
Preferably, in the step S3, the opening of the air holes is performed by a laser drilling device, and the air holes opened in the step S3 are all the composite air holes;
the air hole parameters in the step S2 include the number of air holes to be opened, the cooperative length coefficient of the number of air hole units contained in the composite air hole, and the pulse time.
The ventilation rate of the cigarettes can be better ensured through the quantity of the air holes, the quantity of the air hole units contained in the composite air holes, the cooperative length coefficient of the air hole units and the pulse time, and the influence on the structural strength of the cigarettes is reduced as much as possible.
The number of the air holes is regulated to set the number of the air hole units overlapped by the strip-shaped holes in each composite air hole, the circle centers of the overlapped air hole units are ensured to be positioned at the same axial position of the cigarette, and the number of the air hole units overlapped in a single composite air hole is not more than 16; and the length coefficient is adjusted to set the length of each composite air hole. The larger the overlapping area of the air hole units is, the closer the composite air hole is to a rectangle, the more stable the punching quality is, every two adjacent air hole units are, the single-side intersection point (overlapping part) of the outer circumference of the latter air hole unit and the horizontal diameter is located between the outer circumference of the former air hole unit and the two intersection points of the horizontal diameter, in the actual punching process, the degree of overlapping degree of the connected air hole units is controlled by adjusting the number and the length coefficient of the air hole units overlapped in the single composite air hole, when the length coefficient is higher, the overlapping number is increased, and when the length coefficient is lower, the overlapping number can be properly reduced. That is, the length coefficient is a parameter reflecting the length of the composite pore. When other parameters are determined, a larger length coefficient represents a longer composite air hole, and a smaller length coefficient represents a shorter composite air hole. The pulse time is the time required for opening a single air hole unit, and by adjusting the value, the laser is used for ensuring that the laser completely penetrates through the single-side surface of the cigarette and the residual energy does not change the appearance of the inner surface of the cigarette on the opposite side, and the pulse time is further used for adjusting the diameter of the single overlapped air hole unit on each composite air hole.
Preferably, the step S2 includes the steps of:
s21, determining the number of air holes required to be formed in the cigarette;
s22, determining the number n of the air hole units and the length system alpha% contained in the composite air hole, wherein the numerical ratio of the number n of the air hole units to the length system alpha% is in the following range: alpha/n is more than 3.5 and less than 7.5;
s23, determining pulse time of the air hole unit.
That is, in this embodiment, when determining the punching parameters, the number of the opened air holes, the number of air hole units contained in the composite air holes, the cooperative length coefficient, and the pulse time are used as the priority determining parameters, and the steps are performed in a mode of coarse adjustment and then fine adjustment according to the weights of the parameters, so that the punching of the cigarettes can be better realized. On the premise that the cigarettes are perforated, the sizes of the influences of the perforation parameters on perforation are sequentially the number of perforations, the air hole unit cooperative length coefficient contained in the composite air hole and the pulse time.
The number of the air holes is mainly used for realizing coarse adjustment of the ventilation rate value, the length coefficient is used for further adjusting the ventilation rate in cooperation with the number of the air hole units contained in the composite air holes, meanwhile, the ventilation stability of the cigarettes is optimized according to the ratio of the length coefficient to the air hole units, the cigarettes are ensured to be perforated through pulse time, the adjustment of the diameter of a cigarette overlapped circle is realized through adjusting the parameter, and finally the ventilation rate of the cigarettes is accurately and finely adjusted.
Firstly, the number of air holes to be opened is determined, the ventilation of the cigarettes and the number of the air holes are in positive correlation, the corresponding opening number of the air holes is adjusted according to the relation, and further, when the ventilation rate is required to be more than 50%, the air holes are required to be punched in a strip shape and are not lower than 4.
Secondly, determining the number of air hole units and the length coefficient contained in the single composite air hole, wherein the numerical ratio range of the length coefficient alpha% to the single-section punching number n is as follows: 3.5 < alpha/n < 7.5, in which range a hole can be made in the cigarette. When the pulse time is fixed, the number of air hole units and the length coefficient contained in the single composite air hole are in positive correlation with the ventilation of the cigarette, the smaller the alpha/n is, the larger the overlapping part of the overlapped circle is, the higher the ventilation rate stability is, and the corresponding parameter adjustment is carried out on the ventilation degree required by the fixation based on the relation. Furthermore, the long length coefficient is not suitable to be set, the punched cigarette is held by four fingers, the thumb is vertical, when the central axis of the cigarette is parallel to the thumb, the outer side of the punched filter stick is pressed, and the cigarette cannot be broken as a reference.
Finally, the pulse time is determined, the pulse time and the punching diameter are in positive correlation in a certain range, and based on the minimum punching pulse time threshold, if the diameter of the superimposed circle is required to be increased, the pulse time is properly increased under the condition of ensuring that the pulse time is not overloaded (the punched cigarettes can be effectively punched).
It will be appreciated that in order to ensure that the cigarettes are effectively pierced when punched. Preferably, step S11 is further included between the step S1 and the step S2, and a lowest threshold value of the pulse time is determined.
The step S11 includes the steps of:
s111, punching the cigarettes through laser punching equipment;
s112, cutting off the punched cigarettes;
s113, measuring the length and the width of the hole pattern.
Specifically, the cut-off tobacco branch is laid under a microscope with a measuring function, the length and the width (the diameter of a single overlapped circle) of the composite air hole are measured positively and negatively, and the ratio of the length of the composite air hole on the inner side and the length of the composite air hole on the outer side is not lower than 80%; the width ratio of the inner and outer composite air holes should be not lower than 90%.
The subsequent parameters can be more accurately selected through the step S11, so that the single-side surface of the cigarette can be effectively penetrated by laser in the punching process.
According to the cigarette punching method for heating cigarettes, the plurality of air hole units are partially overlapped to form the strip-shaped pore channels (namely the composite air holes), the strip-shaped pore channels are uniformly distributed to the whole circumference of the cigarettes at certain intervals, the pore channels with larger air inlet area can be ensured to be punched in the circumference, the ventilation rate of the cigarettes is effectively improved, the cigarettes are not easy to break, the circumferences of the cigarettes are effectively utilized, and the breakage of the cigarettes is prevented. Meanwhile, the appearance of the large-area strip-shaped pore canal is more favorable for improving the stability of cigarette punching, and particularly, the adopted method for forming the strip-shaped pore by superposing small circles weakens the ventilation rate fluctuation caused by the pore size change during single circle punching, so that the ventilation stability of cigarettes after punching can be effectively improved. The hole type of the air holes formed in the cigarettes can be changed while the perforation of the strip-shaped pore channels of the cigarettes is completed by combining the perforation quantity, the quantity of air hole units contained in the single composite air holes, the length coefficient and the pulse time, and the ventilation rate of the cigarettes is effectively adjusted, so that the temperature and the concentration of the smoke of the heated cigarettes are further regulated and controlled. The adopted method for forming the strip-shaped holes by overlapping the small circles is a rectangular pore canal under the recognition of human eyes, and the novelty and the attractiveness of cigarette punching are also improved.
