Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of tobacco products, and particularly to a composite filter rod and a cigarette. Background Art
[0002] Currently, functional materials are often added to the filter rods of cigarette products to modulate the smoke. However, it is often difficult to balance the adsorption and desorption effects. For example, activated carbon has a good adsorption effect and can reduce the miscellaneous gases and harmful components in the smoke. However, it will also absorb the characteristic aroma of the smoke to a certain extent, making the taste lighter, which is not beneficial to Chinese-style cigarettes that emphasize the original aroma of tobacco. Another example is that some other particulate matter with characteristic aroma will desorb and bring the characteristic aroma into the smoke when the smoke flows through. However, since its interior is already filled with characteristic aroma substances, it is difficult to play an adsorption role again, and the effect of absorbing harmful components in the smoke is limited. Summary of the Utility Model
[0003] The purpose of the present disclosure is to provide a composite filter rod and a cigarette to balance the adsorption and desorption effects of the smoke.

[0032] Some embodiments of the present disclosure provide a composite filter rod, which includes at least two modulation segments and a plurality of isolation segments.
[0033] At least two modulation segments have functional materials required for modulating the smoke. Among them, the functional material of at least one modulation segment is configured to adsorb miscellaneous gases and / or harmful substances in the smoke, and the functional material of at least one modulation segment is configured to desorb the flavor substances carried by itself into the smoke. The plurality of isolation segments are alternately arranged with the at least two modulation segments.
[0034] Optionally, referring to Figure 1 , the composite filter rod includes two modulation segments. The two modulation segments include a first filter rod segment 1 and a second filter rod segment 2. Among them, the functional material of the first filter rod segment 1 is configured to adsorb miscellaneous gases and / or harmful substances in the smoke, and the functional material of the second filter rod segment 2 is configured to desorb substances for adjusting the smoke flavor into the smoke.
[0035] In order to enhance the effect of modulating the smoke, the composite filter rod may include three, four or more modulation segments. For example, it may include one modulation segment capable of adsorbing harmful substances in the smoke and two modulation segments capable of desorbing different flavor substances into the smoke.
[0036] Optionally, the functional material is particulate matter. Optionally, the functional material includes at least one of the following: adsorption material particles, flavor material particles, and moisturizing material particles.
[0037] The adsorption material particles are used to adsorb harmful components in the smoke to reduce the tar and harm of the smoke. For example, it may be activated carbon. The flavor material particles are used to add characteristic aromas to the smoke to make the smoke have flavor characteristics. The moisturizing material particles are used to increase the moist feeling of the smoke.
[0038] The composite filter rod provided by the embodiment of the present disclosure includes both at least one modulation segment capable of adsorbing and reducing the harm of the smoke and at least one modulation segment capable of desorbing and enhancing the fragrance of the smoke. And the isolation segments and the modulation segments are alternately arranged. The isolation segments can isolate two adjacent modulation segments, reducing the risk of interaction between different types of functional materials in different modulation segments. Therefore, the composite filter rod provided by the embodiment of the present disclosure can take into account the effects of adsorbing and desorbing the smoke.
[0039] Some embodiments of the present disclosure further provide a cigarette rod, including the aforementioned composite filter rod and a tobacco rod 6. The tobacco rod 6 is connected to one end of the composite filter rod in the length direction.
[0040] The cigarette rod provided by the embodiments of the present disclosure has the advantages of the aforementioned composite filter rod.
[0041] The structure of the composite filter rod of some embodiments of the present disclosure will be further described below.
[0042] In some embodiments, both ends of each modulation section in the length direction of the composite filter rod are respectively connected to two isolation sections and blocked by the two isolation sections respectively, so that the functional material is retained within the corresponding modulation section.
[0043] The isolation section can isolate two adjacent modulation sections and prevent the functional material from detaching from the modulation section where it is located. Moreover, the two end portions in the length direction of the composite filter rod are respectively used as the tobacco end and the near-lip end. Based on the structure of the composite filter rod in the above embodiments, the two end portions in the length direction of the composite filter rod are both isolation sections, which can respectively intercept the tobacco powder in the tobacco rod 6 and prevent the functional material from entering the smoker's mouth.
[0044] In some embodiments, in the length direction of the composite filter rod, there is a gap formed between two adjacent isolation sections, and the modulation section includes a wrapper covering the outer periphery of the gap and a functional material filled in the gap.
[0045] In the above embodiments, the functional material can be directly filled in the gap between two adjacent isolation sections instead of being distributed in the filter material, which can increase the addition amount of the functional material and make the effect of the functional material on modulating the smoke more significant. For example, the functional material in at least one modulation section is activated carbon, and the filling degree of the activated carbon in the gap can reach up to 90%, and the amount of the activated carbon in the gap can reach 40 - 50 mg. When the smoke passes through the modulation section with activated carbon, it can fully contact with the activated carbon, and the tar can be fully adsorbed.
[0046] In some embodiments, at least a part of the wrapper of at least one modulation section is transparent.
[0047] The wrapper may include tipping paper and forming paper. Since the wrapper can be partially or fully transparent, the internal structure and the content such as the functional material of the modulation section can be visually seen, thereby enhancing the visual recognition of the composite filter rod and the sense of consumer value of the cigarette brand.
[0048] Of course, in the case where the demand for the functional material is relatively small, or in the case where the requirement for preventing the functional material from detaching from the modulation section is relatively high, the modulation section can be filled with materials such as filter material as the matrix, and the functional material is distributed in the matrix.
[0049] In some embodiments, at least one modulation section includes a matrix filled with a tobacco tow, and a functional material is distributed in the matrix.
[0050] The tobacco tow can be, for example, a cellulose acetate tow or a polypropylene tow. Optionally, the functional material can be distributed in the gaps between the tobacco tows or directly attached to the tobacco tows.
[0051] In some embodiments, the isolation section is filled with a filter material.
[0052] The filter material can be cellulose acetate or other materials with a filtering function. In different isolation sections, the filter materials can be the same or different materials, as long as they can filter the flue gas and prevent the functional material from detaching from the modulation section where it is located.
[0053] In some embodiments, referring to Figure 1 , at least two modulation sections include a first filter rod section 1 and a second filter rod section 2, and multiple isolation sections include a third filter rod section 3, a fourth filter rod section 4, and a fifth filter rod section 5. The third filter rod section 3, the first filter rod section 1, the fourth filter rod section 4, the second filter rod section 2, and the fifth filter rod section 5 are arranged in sequence along the length direction of the composite filter rod.
[0054] Optionally, the composite filter rod is a five - element composite filter rod. Optionally, the first filter rod section 1 and the second filter rod section 2 have the same length, and the third filter rod section 3 and the fifth filter rod section 5 have the same length. Considering the alternating arrangement of the isolation sections and the modulation sections, the five - element composite filter rod of the above - mentioned embodiment can be prepared based on the process of a three - element composite filter rod. For example, the third filter rod section 3, the first filter rod section 1, and the fourth filter rod section 4 can be first compounded, and on this basis, they can be compounded with the second filter rod section 2 and the fifth filter rod section 5 for the second time.
[0055] Next, referring to Figure 1 , cigarettes of some embodiments of the present disclosure will be illustrated by way of example.
[0056] At least two modulation sections include a first filter rod section 1 and a second filter rod section 2, and multiple isolation sections include a third filter rod section 3, a fourth filter rod section 4, and a fifth filter rod section 5. The third filter rod section 3, the first filter rod section 1, the fourth filter rod section 4, the second filter rod section 2, and the fifth filter rod section 5 are arranged in sequence along the length direction of the composite filter rod. A tobacco rod section 6 is connected to one end of the third filter rod section 3 away from the fifth filter rod section 5. The functional material in the first filter rod section 1 includes adsorption material particles, and the functional material in the second filter rod section 2 includes flavor material particles. The third filter rod section 3, the fourth filter rod section 4, and the fifth filter rod section 5 are all filled with a filter material.
[0057] The flue gas first enters the first filter rod section 1 through the third filter rod section 3. Inside the first filter rod section 1, the adsorption material particles adsorb the miscellaneous gases and harmful substances in the flue gas, playing a role in reducing harm. After the flue gas flows out of the first filter rod section 1, it enters the second filter rod section 2 through the fourth filter rod section 4. Inside the second filter rod section 2, the flavor material particles desorb flavor substances into the flue gas, playing a role in enhancing fragrance. In addition, when the flue gas flows through the third filter rod section 3, the fourth filter rod section 4 and the fifth filter rod section 5, the filter material therein can filter harmful substances such as tar in the flue gas, thereby further enhancing the effect of reducing tar and harm.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not intended to limit them; although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present disclosure or perform equivalent replacements for some technical features, and they should all be covered within the scope of the technical solutions claimed by the present disclosure.
