Description

Middle air-permeable ternary composite filter rod and heating cigarette comprising same

Technical Field

The invention belongs to the field of heated cigarettes, and particularly relates to a middle breathable ternary composite filter stick and a heated cigarette comprising the same.

Background

Along with the attention of consumers to health problems and the improvement of the demand of individualized experience of cigarette products, the tobacco industry continuously responds to the demand upgrade of consumers and develops various heating cigarettes with tar and harm reduction. The cigarette heating mode of the non-combustion type cigarette is different from that of the traditional cigarette product, so that the cigarette heating mode can meet the sensory requirements of consumers on the cigarette product and provide healthier smoking experience.

The existing heating cigarette mainly comprises a smoking core material section, a hollow supporting section, a cooling section and a filtering section, wherein the heating cigarette increases ventilation volume and effectively reduces smoke temperature in order to introduce air, a method of online laser drilling is generally adopted to drill a hole in the hollow supporting section of the heating cigarette, and a forming paper and a tipping paper which are used for drilling the pipe wall of the hollow supporting section and wrapping the hollow supporting section are punched to form a ventilation hole to introduce air, but the method still has the following problems: 1. the method has the advantages that the material and the thickness of the pipe wall of the hollow supporting section are high in requirements in the online laser drilling process, firstly, the material of the pipe wall of the hollow supporting section cannot collapse in the online laser drilling process, and the pipe wall of the hollow supporting section cannot be particularly thick, so that the pipe cannot be punched during online laser drilling; 2. the requirement on laser power in the online laser drilling process is high, and if the laser drilling equipment cannot drill the wall of the hollow support section pipe, the problems of unqualified cigarette heating production and overheating smoke temperature can occur; 3. at present, the ventilation hole is formed by penetrating through the hollow supporting section and wrapping the hollow supporting section and the wrapping paper, outside air directly enters the hollow supporting section through the ventilation hole, the air introducing speed of the ventilation hole is high, the contact area of the introduced air and the flue gas is limited, the mixture is not uniform, the flue gas amount sucked into the mouth of a consumer is increased, the flue gas concentration is low, a large amount of air is obviously doped in the flue gas, and the smoking quality is seriously reduced.

In addition, the outer wall of the supporting section adjacent to the smoking section is usually perforated by the conventional heating cigarette, so that hot smoke and air can be mixed most directly, but after the conventional heating cigarette is inserted into a smoking set, the distance for the heating cigarette to enter the smoking set is deep, so that the vent hole is also positioned at the deep position of the cigarette accommodating cavity of the smoking set, the heating cigarette is in close contact with the inner wall of the cigarette accommodating cavity, so that the air quantity introduced by the vent hole is very small, and the effects of cooling the smoke and increasing the smoke quantity are not obvious.

In addition, the mode that adopts physics to punch makes the heating cigarette pipe wall ventilative still have the problem that ventilative volume is unadjustable, ventilative position is fixed, because physics punches and introduces the air, can only punch where, and then introduces ambient air from where and ventilates the cooling, and ventilative volume this is fixed along with the size in hole. However, the ventilation and ventilation position of the heated cigarette is desirably adjustable as the material of the smoking section is changed, or as the smoking set is changed.

Therefore, it is desirable to design a heating cigarette which can not only ensure the cooling effect of the smoke, but also ensure the smoke amount and the smoke quality, and the ventilation amount and the ventilation degree of the heating cigarette can be adjusted.

The present invention has been made to solve the above problems.

The cigarette structure can more flexibly control the ventilation amount and the ventilation position of the smoke extraction section 2 by controlling the length of the tipping paper 5.

As shown in fig. 1-3, the heated cigarette sample 1 with the middle ventilation type ternary composite filter stick in the embodiment sequentially comprises a smoking section 1, a supporting and blocking section 6, a smoke extraction section 2 and a functional filter stick section 3 from the far lip end to the near lip end;

the supporting blocking section 6 and the functional filter rod section 3 do not have an air permeability function; the smoke extraction section 2 has a ventilation function, and outside air can enter the interior of the heated cigarette through the smoke extraction section 2; the tipping paper 5 only partially wraps the smoke extraction section 2, and the forming paper 4 is only arranged on the outer side of the partial area of the far lip end of the smoke extraction section 2, and the tipping paper 5 is not wrapped; the forming paper 4 is air permeable and the tipping paper 5 is air impermeable.

The flue gas extraction section 2 is of a hollow structure and comprises a pipe wall 21 and a pipe cavity 22, the pipe wall 21 is not required to be perforated, the pipe wall 21 has a ventilation function, vent holes are formed in the pipe wall 21, and outside air can enter the pipe cavity 22 through the vent holes in the pipe wall 21.

The tipping paper 5 covers 1/2 of the axial length of the smoke extraction segment 2. The air permeability of the formed paper 4 was 1000 CU. The supporting and blocking section 6 is a hollow paper tube.

The pipe wall 21 is formed by bonding and extruding particles, and pores among the particles after forming play a natural ventilation role;

the particle diameter is 200-25000 microns; after the particles form the wall of the hollow tube, the thickness of the wall 21 is 1.5mm, and the pores among the particles in the wall 21 are dispersed, and the porosity is 50%. The particles are selected from inorganic particulate alumina. The binder between the particles is polylactic acid.

Example 2

This example was compared with example 1 as a comparative example, as shown in fig. 4. The embodiment of the heated cigarette sample 2 with the middle breathable ternary composite filter stick is different from the embodiment 1 in that the heated cigarette sample 2 sequentially comprises a smoking section 1, a smoke extraction section 2, a supporting blocking section 6 and a functional filter stick section 3 from the far lip end to the near lip end;

Example 3

For the heated cigarette sample 1 prepared in example 1 and the heated cigarette sample 2 prepared in example 2, smoking sensory evaluation was performed on the cigarette samples by 20 professional sensory evaluation staff of provincial level or higher according to the qynzy.j07.022-2015 standard, and the results after smoking evaluation were averaged, thereby obtaining the following table 1. Meanwhile, when the sensory evaluation personnel performs suction sensory evaluation on the cigarette sample, the temperature of the smoke entering the oral cavity of the sensory evaluation personnel is measured, and an average value is obtained. Wherein the smoke temperature of the heated cigarette sample 1 entering the oral cavity of the sensory panel smoker is 37.1 ℃, and the smoker feels the temperature just suitable for smoking. While the smoke temperature of the heated cigarette sample 2 entering the smoker's mouth was 39.6 ℃, the smoker felt a slight mouth burn, which was slightly less perceived as smoking than the heated cigarette sample 1 of example 1.

TABLE 1 novel cigarette sensory quality recording chart

The standard is as follows: QYNZY.J07.022-2015

As can be seen from table 1 above, the smoke amount of the heated cigarette sample 1 is also larger, and the score is slightly higher than that of the heated cigarette sample 2 in both aroma, fragrance and taste, that is, the ventilation section is properly moved to the side close to the lip end, so that in practical application, the cooling effect and the smoke amount increasing effect on the smoke are better, which is indeed unexpected.
