Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cigarettes, and more particularly relates to a novel tobacco cigarette with partitioned cooling and a cooling method. BACKGROUND

[0002] The aerosol generated in a cigarette product usually carries a certain amount of heat. In the smoking process, the aerosol with a high temperature usually needs to be cooled to a suitable temperature for the mouth by the cooling part in the filter, so as to meet the needs of the consumer.

[0003] However, the heat exchange of the aerosol in the cooling part must be accompanied by the cooling process. Since the aerosol temperature itself is high, the heat exchange process will increase the temperature of the cooling part. This will cause the surface temperature of the cooling part to approach the temperature of the aerosol, resulting in a decrease in the cooling effect. At the same time, the lip mucosa tissue of the consumer will be in direct contact with the cooling part of the filter during the smoking process, which will cause a burning sensation in the mouth, especially during a one-time heavy smoking process.

[0004] In the prior art, air holes are provided on the surface of the filter, and normal temperature air is introduced through the air holes to effectively reduce the inlet temperature after mixing with the high temperature aerosol. However, high temperature aggregation may still occur on the surface of the cooling section. Therefore, it is necessary to optimize and improve the cooling section of the cigarette structure to reduce the surface temperature of the cooling section during smoking. SUMMARY

[0005] In the prior art, the high temperature aerosol in the cooling section of the cigarette structure mixes with normal temperature air during the smoking process, which causes high temperature aggregation in the cooling section, resulting in a high surface temperature of the cooling section, and causing the consumer to feel uncomfortable during the smoking process, thereby affecting the smoking experience. The tobacco cigarette with partitioned cooling provided by the present application can effectively reduce the surface temperature of the cooling section during the smoking process and maintain a low level.

[0006] The specific implementation scheme of the present application is as follows:

[0007] A tobacco cigarette with partitioned cooling, comprising: a tobacco section, a support section, a cooling section, and a filter section, which are connected by a wrapping paper.

[0008] The tobacco section is filled with a smoking material and is connected to the support section.

[0009] The support section is a hollow structure distributed along the axial direction, and the two ends of the support section are connected to the tobacco section and the cooling section.

[0010] The cooling section is a hollow structure, and is provided with a partition wall along the axial direction, which divides the cooling section into a central region and a lateral region along the radial direction. The outer wall of the cooling section is further provided with an air hole for connecting the lateral region with the outer surface of the wrapping paper. The two ends of the cooling section are connected with the supporting section and the filtering section.

[0011] The filtering section is filled with filtering material and is connected with the cooling section.

[0012] Preferably, the connection area between the central region of the cooling section and the hollow structure of the supporting section is larger than the connection area between the lateral region of the cooling section and the hollow structure of the supporting section.

[0013] Preferably, the cooling section is provided with a plurality of lateral regions along the radial direction and around the circumference.

[0014] Preferably, the lateral regions are uniformly distributed around the circumference.

[0015] Preferably, the air hole is arranged at the center of the outer wall of each lateral region.

[0016] Preferably, the air hole is arranged at the side connected with the supporting section along the axial direction of the cooling section.

[0017] Preferably, the lateral region is arranged in a spiral structure along the axial direction.

[0018] Preferably, the center line of the lateral region is parallel to the axial line of the central region.

[0019] Preferably, the outer wall is provided with a rough surface structure.

[0020] A tobacco cigarette cooling method with a partitioned cooling structure, comprising the following steps:

[0021] (1) heating the tobacco section to generate aerosol;

[0022] (2) the aerosol is concentrated in the hollow structure of the supporting section;

[0023] (3) the aerosol is divided into the central region and the lateral region through the cooling section, and the lateral region introduces normal temperature air through the air hole to mix with the aerosol;

[0024] (4) after the aerosol is divided into the central region and the lateral region, it enters the filtering section, and the temperature of the smoke in the filtering section is balanced.

[0025] Compared with the prior art, the tobacco cigarette provided by the application effectively reduces the surface temperature of the cooling section by partitioning the cooling section while introducing normal-temperature air through the air holes, so that the surface temperature is kept at a low level to avoid discomfort to the consumer, and the smoke concentration in the central area is not affected, reducing the influence of cooling on the taste of the smoke and improving the smoking experience of the consumer.

[0031] In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0033] It is to be understood that the structures, proportions, sizes, etc. shown in the drawings of the present disclosure are merely used to cooperate with the content disclosed in the present disclosure for understanding and reading by those skilled in the art, and are not used to limit the defined conditions that can be implemented by the present application, and therefore do not have technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application.

[0034] The present application is directed to the structure of the existing cigarette, especially the structure of the heated cigarette, due to the heating of the tobacco segment in a very short time, the high-temperature aerosol in the cooling segment is mixed with the normal-temperature air during the consumer's smoking process, which causes the high-temperature aggregation in the cooling segment, resulting in a higher surface temperature of the cooling segment, so that the consumer feels uncomfortable during the smoking process, thereby affecting the smoking experience. The tobacco cigarette with partition cooling provided by the present application can effectively reduce the surface temperature of the cooling segment during the smoking process and maintain it at a lower level through the structural design of the cooling segment.

[0035] The technical solutions of the present application will be further described below:

[0036] As shown in Figure 1 In a specific embodiment, the tobacco cigarette with partition cooling provided by the present application comprises: a tobacco segment 1, a support segment 2, a cooling segment 3, and a filter segment 4, which are sequentially arranged along the axial direction from left to right, and are connected and arranged on the surface by wrapping with a wrapping paper 5.

[0037] The tobacco segment 1 is filled with a smoking material for storing flavor, which releases aerosol with aroma after heating through heat conduction, for the consumer to smoke;

[0038] The support segment 2 has a hollow structure distributed along the axial direction for concentrating the aerosol;

[0039] The cooling segment 3 has a hollow structure and is provided with a partition wall 3.3 along the axial direction, which separates the hollow structure of the cooling segment 3 from the outer wall 3.2, and is divided into a central region and a side region from inside to outside along the radial direction. The outer wall 3.2 is further provided with air holes 3.1 along the radial direction, which penetrate the wrapping paper 5, so that the side region is connected with the external environment for introducing normal-temperature air into the side region for cooling;

[0040] The filter segment 4 is filled with a filtering material for filtering the aerosol passing through the cooling segment 3, and finally entering the consumer's mouth for smoking.

[0041] Preferably, since the aerosol needs to be divided when the support section 2 enters the cooling section 3, in order to avoid the influence of the cooling means on the aroma of the aerosol as much as possible, in this embodiment, as shown in the figure, the edge diameter of the central area separated by the partition wall 3.3 of the cooling section 3 is smaller than the inner diameter of the support section 2, and the hollow structure of the support section 2 has a larger connection area with the central area, so that the volume of the aerosol entering the central area is greater than the volume entering the side area. Figure 1

[0042] Further, in the scheme of the present application, the side area formed by the partition wall 3.3 has various arrangements, including but not limited to the side area with the partition wall 3.3 in a ring structure, which completely separates the outer wall 3.2 from the central area, or the partition wall 3.3 surrounds the outer wall 3.2 to form a plurality of groove structures of the side area, as shown in the figure, the partition wall 3.3 divides the cooling section 3 into four side areas with the outer wall as the basis and the other three sides as rectangles, and as shown in the figure, the partition wall 3.3 divides the cooling section 3 into six side areas in a circular arc distribution. Figure 3 Figure 4

[0043] Further, in order to better optimize the cooling effect of the side area, as shown in the figure, when the side area is multiple, the side areas are evenly distributed along the circumference, avoiding the relative concentration of multiple side areas, which causes the outer wall 3.2 to form a high-temperature aggregation. Figure 3 Figure 4

[0044] Preferably, as shown in the figure, the air hole 3.1, as a channel for the side area to communicate with the outside, in order to better introduce the normal temperature air from the outside, the air hole 3.1 is arranged at the center of the outer wall 3.2 region of each side area, facilitating the normal temperature air to enter each side area and better mixing with the aerosol for cooling. Figure 3 Figure 4 Further, in the scheme of the present application, since the air hole 3.1 is a channel for introducing normal temperature air from the outside, in order to ensure the cooling effect of the air hole 3.1, as shown in the figure, the air hole 3.1 should be arranged on the side close to the support section 2 in the cooling section 3; at the same time, in order to further improve the cooling effect, a plurality of air holes 3.1 can be arranged in each side area, and each air hole 3.1 should fall within the corresponding side area.

[0045] Figure 1

[0046] ​​​​​​​​To increase the axial cooling distance of the side area in the cooling section 3, in other embodiments, the side area can also be arranged in a spiral structure in the cooling section 3, and the spiral center line coincides with the axial center line of the central area, and the spiral is arranged along the cooling section 3 from the support section 2 to the filter section 4, so that the length of the side area is greater than the length of the central area, facilitating heat dissipation.

[0047] In the present embodiment, as shown in Figure 1 With Figure 2 the center line of the side area is parallel to the axial center line of the central area, so that the side area is a straight-through structure arranged along the axial line of the cooling section 3, and mixes with the aerosol in the central area after cooling.

[0048] Preferably, in other embodiments, the outer wall 3.2 is provided with a rough surface structure on the surface, which increases the surface area of the outer wall 3.2 and has a larger heat dissipation area, so that it can continuously maintain a lower surface temperature during smoking, so that the consumer has a good smoking experience.

[0049] In the present application, a cooling method for the partitioned cooling tobacco cigarette is also provided, which comprises the following steps:

[0050] (1) The consumer uses a heating tool to heat the tobacco section 1, which can be burning or heating the heating tool, and when heated to a certain temperature, the aerosol with smoke flavor is generated in the tobacco section 1 filled with smoke generating material;

[0051] (2) The aerosol is concentrated in the hollow structure of the support section 2, and is also preliminarily cooled;

[0052] (3) When the aerosol passes through the cooling section 3, it enters the central area and the side area respectively due to the isolation of the partition wall 3.3, and in the side area, the air holes 3.1 are arranged on the outer wall 3.2 to introduce normal temperature air to mix with the aerosol for cooling;

[0053] (4) After being cooled by the shunt cooling in the cooling section 3, the aerosol enters the filter section 4, and the filter section 4 balances the smoke temperature, and finally is used for the consumer to smoke.

[0054] The above only describes the embodiments of the present application, and it should be pointed out that for those skilled in the art, improvements can be made without departing from the inventive concept, but these all belong to the protection scope of the present application.
