Description

Technical Field

[0001] The patent of this invention relates to the technical field of heat-not-burn cigarette production, and specifically to a supporting cooling unit with turbulence effect and a heated cigarette containing the same. Background Art

[0002] As consumers pay more attention to health issues and demand for personalized experience of cigarette products, the tobacco industry continues to respond to the upgrading of consumer demand and develop various cigarettes with reduced tar and reduced harm. Among them, heat-not-burn cigarettes are different from traditional cigarette products in that their heating method is different, which enables them to meet consumers' sensory needs for cigarette products while providing a healthier smoking experience.

[0003] Existing heat-not-burn cigarettes mainly include a smoke core material section, a hollow support section, a cooling section and a filter section, wherein the hollow support section not only supports the cigarette, but more importantly, gathers smoke and assists the cooling section in cooling the smoke. At present, the hollow support section mainly adopts a hollow paper tube or a hollow acetate fiber rod, and the problems with both are: 1. The contact area between the smoke and the tube wall of the hollow support section is limited, and effective cooling cannot be achieved; 2. The smoke stays in the hollow support section for a short time, and directly and quickly passes through the hollow support section into the cooling section, and the cooling efficiency of the hollow support section is low; 3. The tube wall is not sufficiently supportive, and will produce a large deformation when passing through the cutter, resulting in a decrease in the support performance of the support cooling unit, or the support cooling unit collapses and deforms during production and transportation, thereby increasing the difficulty of the heat-not-burn cigarette rolling process, seriously affecting production efficiency and product quality. Therefore, in order to further cool the flue gas, the current approach mainly focuses on improving the cooling materials in the cooling section or directly increasing the amount of cooling materials. However, most cooling materials are phase change materials. After a few puffs, the phase change materials collapse and block the airflow channel, greatly increasing the inhalation resistance and affecting the inhalation experience.

[0004] Therefore, in the field of heat-not-burn cigarettes, people hope to obtain a supporting and cooling unit that has strong supporting force, is not easy to deform and collapse, and takes both cooling and flavor enhancement into consideration.

[0005] The present invention has been proposed in order to solve the above-mentioned problems. Summary of the invention

[0006] The first aspect of the present invention provides a support cooling unit with a turbulent flow effect, wherein the support cooling unit has a tube wall 21 and an axial tube cavity 22;

[0007] The tube wall 21 includes a flow-disturbing component 211 and an inner wrapping layer 212 , and the inner wrapping layer 212 is close to the axial tube cavity 22 ;

[0008] The spoiler component 211 is a circular cylinder, and has a spiral or folded-line spoiler groove 2111 on its outer wall.

[0009] Preferably, the spoiler groove 2111 extends axially or radially.

[0010] Preferably, the width of the spoiler groove 2111 is 0.2-1.0 mm.

[0011] Preferably, the inner wrapping layer 212 is a paper layer, an acetate fiber layer or a polymer non-woven fabric layer.

[0012] Preferably, the spoiler component 211 is formed by rolling a sheet material to form the spoiler groove 2111, and the sheet material is selected from acetate sheet, paper, polyethylene sheet, polypropylene sheet, polyvinyl chloride sheet, polyethylene terephthalate sheet or polylactic acid sheet, and the thickness of the sheet material is 0.1mm-0.8mm.

[0013] Preferably, the spoiler component 211 has a thickness of 0.5 mm to 3 mm.

[0014] Preferably, the spoiler 211 contains a flavoring substance, and the flavoring substance is selected from polyethylene glycol or essence.

[0015] The second aspect of the present invention provides a heating cigarette comprising the filter unit, characterized in that it further comprises: a smoking unit 1 and a filter unit 3; the supporting cooling unit is located between the smoking unit 1 and the filter unit 3;

[0016] The supporting cooling unit and the filtering unit 3 are wrapped by forming paper to form a mouthpiece, and the smoking unit 1 and the mouthpiece are connected by tipping paper;

[0017] The length of the supporting cooling unit is 20%-80% of the total length of the nozzle rod.

[0018] The heated cigarette in the present invention refers to a heat-not-burn cigarette.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The tube wall 21 in the supporting and cooling unit of the present invention includes a spoiler component 211, which is a circular cylinder with a spiral or folded spoiler groove 2111 on its outer wall. Compared with a single sheet, the spoiler groove 2111 and the protrusions defining the spoiler groove 2111 on the sheet are more conducive to improving the resilience of the sheet, thereby improving the resilience of the tube wall 21, further ensuring that the radial compression resistance of the supporting and cooling unit is good, and avoiding the collapse and deformation of the tube wall 21 of the supporting and cooling unit when passing through a cutter or during production and transportation, thereby making the cigarette rolling process of heat-not-burn cigarettes simpler and improving production efficiency.

[0021] 2. The outer wall of the spoiler component 211 of the present invention is provided with a spiral or zigzag spoiler groove 2111, and the spoiler groove 2111 can increase the contact area between the smoke and the supporting cooling unit, thereby achieving more effective cooling.

[0022] 3. The spoiler groove 2111 on the spoiler component 211 of the present invention extends in a spiral or zigzag shape along the axial or radial direction. The spiral or zigzag extension method can change the airflow path of the flue gas in contact with the spoiler component 211, and produce a turbulent phenomenon for the flue gas that flows directly through the supporting cooling unit, thereby increasing the residence time of the flue gas in the supporting cooling unit, preventing the flue gas from directly and quickly passing through the supporting cooling unit, and further achieving cooling of the flue gas.

[0023] 4. In a preferred embodiment of the present invention, the spoiler component 211 contains a flavoring substance, and the flavoring substance is selected from polyethylene glycol or essence. While cooling the smoke, the smoke is further flavored and the smoke volume is increased, thereby improving the consumer's smoking quality. At the same time, the residence time of the smoke in the supporting cooling unit is increased, which will also enhance the flavoring effect of the flavoring substance in the spoiler component 211 on the smoke.

[0030] The present invention is further described in detail below in conjunction with the embodiments and drawings. The embodiments are only intended to illustrate the present invention, but not to limit the present invention.

[0031] Example 1

[0032] This embodiment is the preparation of a heated cigarette sample 1, which includes a smoking unit 1, a supporting and cooling unit 2 and a filtering unit 3; the supporting and cooling unit 2 and the filtering unit 3 are wrapped by forming paper to form a mouthpiece, and the smoking unit 1 and the mouthpiece are connected by tipping paper; the length of the supporting and cooling unit 2 is 40% of the total length of the mouthpiece.

[0033] The support cooling unit has a tube wall 21 and an axial tube cavity 22; the tube wall 21 includes a spoiler component 211 and an inner wrapping layer 212, and the inner wrapping layer 212 is close to the axial tube cavity 22; the spoiler component 211 is a circular cylinder, and a spiral spoiler groove 2111 is provided on its outer wall, and the spoiler groove 2111 extends in the axial direction, and the width of the spoiler groove 2111 is 0.4 mm, see Figure 2 shown.

[0034] The inner wrapping layer 212 is a paper layer. The spoiler 211 is formed by rolling a sheet material to form the spoiler groove 2111. The sheet material is selected from an acetate sheet, and the thickness of the sheet material is 0.5 mm. The thickness of the spoiler 211 is 1 mm. The spoiler 211 contains a flavoring substance, and the flavoring substance is selected from polyethylene glycol.

[0035] Example 2

[0036] This embodiment is the preparation of heated cigarette sample 2. The difference between heated cigarette sample 2 and heated cigarette sample 1 is that the outer wall of the spoiler component 211 has a broken line spoiler groove 2111, the spoiler groove 2111 extends along the axial direction, and the width of the spoiler groove 2111 is 0.4 mm. Figure 3 shown.

[0037] Comparative Example

[0038] This comparative example is the preparation of a heated cigarette comparison sample. The difference between the heated cigarette comparison sample and the heated cigarette sample 1 is that the outer wall of the spoiler component 211 has a linear spoiler groove 2111, and the spoiler groove 2111 extends along the axial direction. The width of the spoiler groove 2111 is 0.4 mm. Figure 4 shown.

[0039] Three experts with sensory evaluation qualifications were invited to conduct sensory evaluation on heat-not-burn cigarette sample 1 (Example 1), heat-not-burn cigarette sample 2 (Example 2), and heat-not-burn cigarette control sample (control sample) with reference to QYNZY.J07.022-2015 standard. The results are shown in Table 1 (the average value of the evaluation results of the three sensory evaluation experts). The temperature of the smoke entering the mouth of the evaluation experts was also recorded.

[0040] Table 1 Sensory quality record of heat-not-burn cigarettes

[0041] Standard basis: QYNZY.J07.022-2015

[0042]

[0043] It can be concluded from Table 1 that since the smoke stays in the mouthpiece for a long time and has a better flavor enhancement effect, the aroma and taste index scores should be significantly higher than those of the control sample.

[0044] During the smoking process, the smoke temperature entering the mouth of the smoking expert was recorded at the same time. It was measured that the smoke temperature of cigarette sample 1 and cigarette sample 2 entering the mouth of the smoking expert was about 36°C, which smokers felt was acceptable. The smoke temperature of the cigarette control sample entering the mouth of the smoking expert was 38°C. Therefore, compared with the linear spoiler groove 2111, the spoiler component 211 with spiral spoiler groove 2111 and zigzag spoiler groove 2111 prepared by the present invention has a better cooling effect.
