Description

Technical Field

[0001] The invention relates to the technical field of tobacco products, and in particular to a composite filter rod with built-in rheological components and a cigarette. Background Art

[0002] Cigarette filter rods in the prior art are usually made of cellulose acetate material to form a cylindrical structure with the same diameter as the cigarette for filtering smoke. When people smoke, the smoke passes through the solid filamentary cigarette filter rod, which will filter out harmful substances such as tar and particulate matter in the smoke, thereby reducing the harm of smoke filtration. However, this filter rod can only perform simple smoke filtration. When the smoke passes through the filter rod, the smoke will not pass through the circular cross-section of the filter rod evenly and completely. Irregular brown substances formed by the filter can be clearly seen at the inlet end of the filter rod. It is obvious that the smoke is not fully filtered at the entrance, and the smoke is not fully mixed during the filtration process of the filter rod, resulting in uneven and full smoke inlet and poor taste. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides a composite filter rod and a cigarette with a built-in rheological firmware. By arranging the rheological firmware in the composite filter rod, the smoke filtering effect is improved, and the smoke can be subjected to rheological collision in the filter rod, so that large particles in the smoke are deposited on the rheological firmware, thereby improving the smoke filtering effect and achieving full mixing of the smoke, increasing the uniformity and mixing fullness of the smoke, and improving the smoking taste.

[0004] The technical solution of the present invention is as follows:

[0005] In a first aspect of the present invention, a composite filter rod with a built-in rheological firmware is provided, comprising a first filter structure near the cigarette end, a cavity structure in the middle, and a second filter structure at the inlet end, wherein the first filter structure, the cavity structure in the middle, and the second filter structure at the inlet end are coated with molding paper on the outside; a cylindrical rheological firmware is provided in the cavity structure, and both ends of the rheological firmware are in contact with the first filter structure and the second filter structure.

[0006] In some embodiments of the present invention, the first filter structure and the second filter structure are cylindrical filter structures filled with cellulose acetate material.

[0007] In some embodiments of the present invention, the diameter of the rheological component is consistent with the diameters of the first filtering structure and the second filtering structure.

[0008] In some embodiments of the present invention, the two ends of the rheological fixture are arranged as hollow structures, a first partition is arranged in the middle of the rheological fixture near the cigarette end, a ring-shaped structure is arranged in the middle of the rheological fixture near the inlet end, and a second partition is arranged inside the ring-shaped structure; a first smoke through hole is arranged on the first partition, and a plurality of second smoke through holes are arranged on the second partition.

[0009] In some embodiments of the present invention, the first partition is arranged in a circular structure and is connected to the inner wall of the rheological component. The annular end face of one end of the annular structure abuts the first partition, and the annular side surface of the annular structure is connected to the inner wall of the rheological component. A cavity structure is formed between the first partition and the second partition in the annular structure.

[0010] In some embodiments of the present invention, a first smoke through hole is provided on the first partition, and the first smoke through hole is arranged at the axial position of the rheological component; a plurality of second smoke through holes arranged on the second partition are arranged at a certain distance radially away from the axis of the rheological component.

[0011] In some embodiments of the present invention, the diameter of the first smoke through hole is greater than the diameter of the plurality of second smoke through holes.

[0012] In some embodiments of the present invention, the plug-in paper is a transparent plug-in paper with no air permeability.

[0013] In some embodiments of the present invention, the rheological component is made of a polymer elastic material.

[0014] In a second aspect of the present invention, a cigarette is provided, comprising the composite filter rod with built-in rheological component.

[0015] One or more technical solutions of the present invention have the following beneficial effects:

[0016] The composite filter rod and cigarette with built-in rheological hardware provided by the present invention can improve the smoke filtering effect by setting the rheological hardware in the composite filter rod, and can make the smoke undergo rheological collision in the filter rod, thereby achieving full mixing of the smoke, increasing the uniformity and mixing fullness of the smoke, and improving the smoking taste;

[0017] Among them, the rheological firmware can be set to change the structure of the smoke rheology, so as to achieve the filtration of smoke and increase the collision of smoke in the composite filter rod, specifically:

[0018] When an annular structure is provided in the middle of the rheological component, smoke enters the annular cavity of the annular structure through the first smoke through hole from one hollow end of the rheological component, and then flows out through the multiple first smoke through holes at the other end. During the entire inhalation process, due to the different structures and number settings of the smoke through holes at both ends of the annular cavity, the smoke is fully mixed and collided inside the annular cavity when flowing through the rheological component, so that the smoke can be effectively adsorbed on the rheological component and the smoke is mixed more fully.

[0019] When an annular structure is provided in the middle of the rheological fixture, the smoke is gathered by the hollow end on the left side of the rheological fixture 1, and then enters the formed annular cavity through the first smoke through hole. After turbulence and mixing are formed in the annular cavity, large particles are deposited on the annular structure, and then flow out through the four second smoke through holes. The provision of multiple second smoke through holes can increase the smoothness of smoke extraction, and at the same time, cooperate with the stepped structure formed by the annular structure on the right side of the second partition and the rheological fixture to make the smoke diverge and mix.

[0020] During the entire inhalation process, due to the different structures and quantity settings of the first smoke through hole and the second smoke through hole, the smoke is fully mixed and collided at the annular structure when flowing through the rheological fixture, so that the smoke can be effectively adsorbed on the rheological fixture and the smoke is mixed more fully.

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Since traditional cigarette filter rods are mainly made of cellulose acetate material, after lighting a cigarette, the smoke is filtered through the solid filamentary cigarette filter rod made of cellulose acetate material by artificial inhalation, and harmful components such as tar and particulate matter in the smoke will be blocked by the filamentary structure in the filter rod, thereby achieving the effect of harm reduction. However, this method has limited filtering efficiency for smoke, and at the same time, in the process of smoke from one end of the filter rod to the inlet end, the rheology of the smoke is single, and the overall mixing degree of the smoke is insufficient, which also leads to a large room for improvement in the smoking taste and aroma of cigarettes.

[0028] Special filter rods currently on the market often improve smoke filtration by changing the filter rod material or setting up a multiple structure for the filter rod, or add flavor materials to change the taste of the smoke. However, there is currently no relevant technology for achieving smoke harm reduction by changing the smoke rheology and improving the degree of smoke mixing to improve the smoke taste.

[0029] Example 1

[0030] In a typical embodiment of the present invention, Figure 1-4 As shown, a composite filter rod with a built-in rheological firmware is proposed, including a first filtering structure near the cigarette end, a cavity structure in the middle and a second filtering structure at the inlet end, and the outside of the first filtering structure, the cavity structure in the middle and the second filtering structure at the inlet end are coated with molding paper; a cylindrical rheological firmware 1 is provided in the cavity structure, and both ends of the rheological firmware 1 are in contact with the first filtering structure and the second filtering structure.

[0031] When inhaling, the smoke can completely reach the middle cavity structure from the first filtering structure. Since the rheological firmware 1 is provided in the cavity structure, the end of the rheological firmware 1 is aligned and in contact with the end face of the acetate filter rod of the first filtering structure. The smoke needs to pass through the rheological firmware 1 to achieve mixed filtration of the smoke before reaching the third section of the acetate filter rod filtering structure for filtration again.

[0032] Through the above-mentioned overall composite structure setting, the smoke is preliminarily filtered after passing through the first filtering structure and enters the cavity structure with the rheological firmware 1 built in the middle. After the rheological firmware 1 is structurally set, the rheological control of the smoke can be achieved, including the first smoke through hole 3 and the second smoke through hole 5 that are arranged in coordination with each other, or the smoke flow channel with a variable internal diameter of the rheological firmware 1 with a stepped structure at both ends, which changes the flow rate of the smoke so that it is fully mixed, and the smoke collides and mixes on the structure of the rheological firmware 1 and is deposited on the rheological firmware 1, thereby achieving further filtering, reducing tar and reducing harm of the smoke, and making the smoke mixing more sufficient, achieving the effect of enhancing flavor and retaining moisture.

[0033] The present invention provides a composite filter rod and cigarette with built-in rheological firmware. By setting the rheological firmware 1 in the composite filter rod, the smoke filtering effect is improved, and the smoke can undergo rheological collision in the filter rod, thereby achieving sufficient mixing of the smoke, increasing the uniformity and mixing fullness of the smoke, and improving the smoking taste.

[0034] Furthermore, the first filter structure and the second filter structure are made of a cylindrical filter structure filled with cellulose acetate material. By filling the first filter structure and the second filter structure with cellulose acetate material to form a cylindrical filter structure, harmful substances in smoke can be reduced while controlling costs.

[0035] Furthermore, the diameter of the rheological component 1 is consistent with the diameters of the first filtering structure and the second filtering structure.

[0036] By setting the diameter of the rheological fixture 1 and the first and second filter structures to be consistent, it is convenient to use molding paper for packaging, while ensuring the sealing effect of the cylindrical sides of the rheological fixture 1 and the first and second filter structures to prevent smoke leakage.

[0037] Furthermore, the two ends of the rheological fixture 1 are arranged as hollow structures, a first partition 2 is arranged in the middle of the rheological fixture 1 near the cigarette end, a ring-shaped structure 6 is arranged in the middle of the rheological fixture 1 near the inlet end, and a second partition 4 is arranged inside the ring-shaped structure 6; a first smoke through hole 3 is arranged on the first partition 2, and a plurality of second smoke through holes 5 are arranged on the second partition 4.

[0038] In this embodiment, if Figure 2 As shown, the annular structure 6 is arranged in the middle of the entire rheological component 1, so that the entire rheological component 1 forms a left hollow structure from left to right, a structure with the annular structure 6 in the middle and a hollow structure on the right. The second partition 4 is arranged in the middle of the entire annular structure 6, so that the first partition 2 and the second partition 4 form an annular cavity structure, and the right side of the annular structure 6 and the rheological component 1 form a stepped hollow structure.

[0039] Furthermore, the first partition plate 2 is arranged in a circular structure and is connected to the inner wall of the rheological component 1. The annular end face of one end of the annular structure 6 abuts against the first partition plate 2. The annular side surface of the annular structure 6 is connected to the inner wall of the rheological component 1. A cavity structure is formed between the first partition plate 2 and the second partition plate 4 in the annular structure 6.

[0040] In this embodiment, the first partition 2 of the circular structure is vertically and tightly connected to the inner wall of the rheological component 1 to prevent air leakage. The annular end surface of one end of the annular structure 6 abuts against the first partition 2. The annular side surface of the annular structure 6 is tightly connected to the inner wall of the rheological component 1 to stabilize the structure.

[0041] Furthermore, a first smoke through hole 3 is provided on the first partition plate 2 and is arranged at the axial position of the rheological component 1 ; a plurality of second smoke through holes 5 are arranged on the second partition plate 4 and are arranged at a certain distance radially away from the axis of the rheological component 1 .

[0042] Furthermore, the diameter of the first smoke through hole 3 is greater than the diameter of the plurality of second smoke through holes 5 .

[0043] In this embodiment, there is one first smoke through hole 3, which is located on the first partition 2 at the axial position of the cylindrical rheological component 1, and there are four second smoke through holes 5, which are evenly distributed on the second partition 4 and radiate around based on the axial position of the cylindrical rheological component 1, and the diameter of the first smoke through hole 3 is greater than the diameter of the second smoke through hole 5. In addition, the first smoke through hole 3 provided on the first partition 2 and the four second smoke through holes 5 provided on the second partition 4 are staggered, so that after the smoke passes through the first smoke through hole 3, it is mixed and deposited in the cavity formed by the first partition 2 and the second partition 4, and then discharged through the second through hole, and gradually diverges through the stepped structure formed by the annular structure 6 on the right side of the second partition 4 and the rheological component 1, and reaches the inlet end through the second filtering structure.

[0044] In this arrangement, when an annular structure 6 is provided in the middle of the rheological fixture 1, smoke is gathered from the hollow end on the left side of the rheological fixture 1, and then enters the formed annular cavity through the first smoke through hole 3. After turbulence and mixing are formed in the annular cavity, large particles are deposited on the annular structure 6, and then flow out through the four second smoke through holes 5. The arrangement of multiple second smoke through holes 5 can increase the smoothness of smoke suction, and at the same time, cooperate with the stepped structure formed by the annular structure 6 on the right side of the second partition 4 and the rheological fixture 1 to make the smoke disperse and mix. During the entire suction process, due to the different structures and quantity settings of the first smoke through hole 3 and the second smoke through hole 5, the smoke is fully mixed and collided at the annular structure 6 when flowing through the rheological fixture 1, so that the smoke can be effectively adsorbed on the rheological fixture 1, and the smoke mixing is more sufficient.

[0045] Furthermore, the shaping paper is transparent shaping paper and has no air permeability.

[0046] In this embodiment, the shaping paper is transparent shaping paper with no air permeability. On the one hand, it can ensure the sealing of smoke when passing through the filter rod to prevent smoke leakage. On the other hand, the flow and mixing process of smoke in the guide piece can be observed by the smoker through the transparent shaping paper, which increases the interest of smoking.

[0047] Furthermore, the rheological component 1 is made of a polymer elastic material.

[0048] In this embodiment, the rheological fixture 1 is made of a polymer elastic material, and the material has a certain collision adsorption effect. When the smoke passes through the drainage piece, the smoke will collide with the structural wall of the smoke drainage groove, which can increase the adsorption of tar and particulate matter in the smoke, further improving the filtering effect.

[0049] In a second aspect of the present invention, a cigarette is provided, comprising the composite filter rod with built-in rheological component.

[0050] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
