Description

Technical Field

[0001] The patent of this invention relates to the technical field of heated cigarette production, and specifically to a support unit that has both cooling and flavoring functions 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 heated cigarettes mainly include a smoking unit, a support unit, a cooling section and a filter unit, wherein the support unit is mostly made of two to three layers of paper substrates stacked together. The material properties of the paper substrate limit the tube wall thickness of the paper tube, which can generally only be 0.02-0.05mm. If the tube wall thickness is too small, the paper tube will not be able to support the tube enough, and a large deformation will occur when it passes through the cutter, resulting in a decrease in the supporting performance of the support unit, or the support unit will collapse and deform during production and transportation, thereby increasing the difficulty of the heated cigarette rolling process and seriously affecting production efficiency and product quality.

[0004] In addition, the support unit not only supports the cigarette, but also gathers the smoke and assists the cooling section in cooling the smoke. In order to improve the smoking quality of consumers, it is also necessary to add flavor to the smoke. However, the cooling and flavoring effects of the current paper tube support unit on the smoke are still poor. The reasons are as follows: 1. The contact area between the smoke and the support unit wall is limited, and effective cooling cannot be achieved; 2. The paper tube wall absorbs less fragrance. If the absorption of fragrance is to be increased, the supporting performance of the paper tube wall will inevitably be affected.

[0005] Therefore, it is desirable to develop a support unit with strong support force and cooling effect to assist the cooling section in achieving better cooling and aroma enhancement effects on the flue gas, or even to replace the cooling section.

[0006] The present invention has been proposed in order to solve the above-mentioned problems. Summary of the invention

[0007] The present invention provides a support unit that has both cooling and aroma enhancement functions, the support unit comprising a tube wall (21) and an axial tube cavity 22;

[0009] The temperature-reducing and aroma-enhancing component 23 includes a supporting frame 231 and an adsorption component 232 , and the adsorption component 232 has aroma-enhancing substances adsorbed thereon.

[0010] Preferably, the cross-sectional area of ​​the temperature-reducing and aroma-enhancing component 23 is in the shape of honeycomb briquettes or a "R" shape.

[0012] Preferably, the temperature-reducing and aroma-enhancing component 23 is a multi-layer structure, which is composed of a sheet-like supporting frame 231 and a sheet-like adsorption component 232.

[0013] When the cooling and aroma-enhancing component 23 is a multi-layer structure, the material of the supporting frame 231 is selected from high-weight paper; the weight of the high-weight paper is greater than 60g / m 2 The adsorption component 232 is cigarette paper, which is preferably prepared by an adhesive compounding method and rolled into the cooling and flavoring component 23 after compounding.

[0014] In another preferred embodiment, the temperature-reducing and aroma-enhancing component 23 is an integrated structure, which is formed by a uniform composite of a support frame 231, an adsorption component 232, an aroma-enhancing substance and an adhesive.

[0015] When the cooling and flavoring component 23 is an integrated structure, the material of the support skeleton 231 is selected from polymer materials in the form of fiber bundles; the polymer materials include polylactic acid, polypropylene, and starch polymers; the adsorption component 232 is selected from mesoporous materials, and the mesoporous materials are selected from activated carbon and diatomaceous earth; the adhesive is selected from the YQ15-2012 "List of Substances Permitted for Use of Tobacco Materials".

[0017] The second aspect of the present invention provides a heated cigarette, which comprises: a smoking unit 1, a supporting unit 2 and a filter unit 4;

[0018] The support unit 2 and the filter unit 4 are wrapped by forming paper to form a mouthpiece, and the smoking unit 1 and the mouthpiece are connected by tipping paper;

[0019] The length of the support unit 2 is about 25% to 75% of the total length of the nozzle rod.

[0020] Preferably, the heated cigarette further comprises an empty tube section 3, which is located between the support unit and the filter unit 4, the support unit, the empty tube section 3 and the filter unit 4 are wrapped by forming paper to form a mouthpiece, and the smoking unit 1 and the mouthpiece are connected by tipping paper;

[0021] The length of the support unit is about 25% to 75% of the total length of the nozzle rod.

[0022] The heated cigarette in the present invention refers to a heat-not-burn cigarette.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The tube wall 21 of the support unit of the present invention is made of high-weight paper, high-molecular polymer material and silica gel, which ensures that the support unit has good radial pressure resistance and avoids the collapse and deformation of the tube wall 21 when the support unit passes through a cutter or during production and transportation, thereby making the heated cigarette rolling process simpler and improving production efficiency.

[0025] 2. The support unit of the present invention is located downstream of the smoke generating unit 1 and is adjacent to the smoke generating unit 1. When the smoke generated by the smoke generating unit 1 passes through the support unit, the presence of the cooling and aroma enhancing component 23 can increase the contact area between the smoke and the support unit, further improving the cooling and aroma enhancing effect and improving the quality of smoking for consumers. In addition, compared with the smoke first passing through the empty tube unit 3 and then passing through the support unit, the cooling and aroma enhancing component 23 of the present invention is adjacent to the smoke generating unit 1, and the cooling material utilization rate of the cooling and aroma enhancing component 23 is higher, and the cooling and aroma enhancing effect is better. The cooling and aroma enhancing component 23 can utilize the high-temperature smoke caused by the nearby smoking material to release aroma and cool the smoke.

[0026] 3. The heated cigarette prepared by the present invention is applied to the center-heated cigarette product. When the cigarette is inserted into the smoking device, the presence of the cooling and flavoring component 23 can prevent the movement of the smoking material caused by the heating element being inserted into the smoking unit. That is to say, the support unit of the present invention can provide the flavoring and cooling effects while taking into account the supporting effect.

[0027] 4. The cooling and aroma enhancement component 23 in the support unit of the present invention comprises a support frame 231 and an adsorption component 232, and the adsorption component 232 is adsorbed with aroma enhancement substances and aerosol generating agents. The support frame 231 is used to improve the support performance of the cooling and aroma enhancement component 23, and prevent the movement of the smoking material caused by the heating element being inserted into the smoking unit, while the adsorption component 232 can adsorb a large amount of aroma enhancement substances and aerosol generating agents, so as to meet the aroma enhancement and cooling function of the support unit.

[0028] 5. In a preferred embodiment of the present invention, the heated cigarette filter rod also has a hollow tube unit 3, which is located between the support unit and the filter unit 4. The porous structure is connected to the cavity structure, which is beneficial to the formation and mixing of smoke, realizes smoke formation and cooling, and can reduce the filter rod interception efficiency and increase the smoke delivery efficiency.

[0029] 6. The temperature-reducing and aroma-enhancing component 23 is a porous structure, which can reduce the smoke contact area of ​​the filter rod, reduce the interception efficiency, and increase the smoke delivery efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
