[0036] The application provides a cigarette filter stick, which comprises a filter stick body and a formed paper wrapped around the outer periphery of the filter stick body; a cavity is formed in the filter stick body, and a gas-permeable partition is arranged in the cavity, which divides the cavity into a first cavity and a second cavity; particle matter is arranged in the first cavity and the second cavity respectively; the first cavity is wrapped by a first transparent formed paper, and the second cavity is wrapped by a second transparent formed paper; a plurality of through holes are formed in the first transparent formed paper and the second transparent formed paper respectively; the through holes in the first transparent formed paper gradually become sparse in the clockwise direction; and the through holes in the second transparent formed paper gradually become sparse in the counterclockwise direction. The density directions of the through holes in the first transparent formed paper and the second transparent formed paper are opposite, so that the particle matter in the first cavity and the particle matter in the second cavity can flow in opposite directions during smoking, which can better meet the needs of consumers, better improve the smoke filtering effect, and better meet the smoking experience of consumers at different levels.

[0037] Please refer to Figures 1 to 3 The embodiment provides a cigarette filter stick 100, in particular a filter stick capable of realizing double-layer window particle reverse flow.

[0038] The cigarette filter stick 100 comprises a filter stick body 10 and a formed paper 20 wrapped around the outer periphery of the filter stick body 10; a cavity 11 is formed in the filter stick body 10, and a gas-permeable partition 12 is arranged in the cavity 11, which divides the cavity 11 into a first cavity 111 and a second cavity 112. The gas-permeable partition 12 refers to a component capable of separating the first cavity 111 and the second cavity 112 and not affecting the normal flow of smoke during smoking. Particle matter 30 is arranged in the first cavity 111 and the second cavity 112 respectively. The first cavity 111 is wrapped by a first transparent formed paper 21, and the second cavity 112 is wrapped by a second transparent formed paper 22. Specifically, the gas-permeable partition 12 can be a composite sheet with thin thickness and good gas permeability.

[0039] It should be noted that the formed paper 20 can be entirely transparent or partially transparent, as long as the formed paper 20 is transparent at the positions corresponding to the first cavity 111 and the second cavity 112, so that the internal structures of the first cavity 111 and the second cavity 112 can be directly observed.

[0040] A plurality of (at least three) through holes 40 are formed on the first transparent forming paper 21 and the second transparent forming paper 22, respectively, that is, a plurality of through holes 40 are formed on the first transparent forming paper 21, and a plurality of through holes 40 are formed on the second transparent forming paper 22. In the clockwise direction, the density of the through holes 40 formed on the first transparent forming paper 21 gradually decreases. In the counterclockwise direction, the density of the through holes 40 formed on the second transparent forming paper 22 gradually decreases. It should be noted that the clockwise direction and the counterclockwise direction are with reference to the same angle direction and the same base point on the forming paper 20.

[0041] That is, the through holes 40 formed on the first transparent forming paper 21 and the second transparent forming paper 22 are sequentially formed in the circumferential direction, and the density direction of the through holes 40 formed on the first transparent forming paper 21 is opposite to the density direction of the through holes 40 formed on the second transparent forming paper 22.

[0042] It can be understood that Bernoulli's effect indicates that when the fluid velocity increases, the pressure on the interface between the object and the fluid will decrease, and vice versa. According to this principle, the through holes 40 with different densities are designed on the forming paper 20. During the smoking process of the cigarette, different pressure differences appear at the through holes 40 with different densities, so that the airflow pressure is smaller at the through holes 40 with high density, and the airflow pressure is larger at the through holes 40 with low density. This air pressure difference can make the particles 30 added in the first cavity 111 and the second cavity 112 rotate. Because the through holes 40 on the first transparent forming paper 21 and the second forming paper 22 in the cigarette filter rod 100 are arranged in a clockwise direction and a counterclockwise direction, respectively, the airflow directions in the first cavity 111 and the second cavity 112 are opposite during the smoking process of the cigarette, and the particles 30 in the first cavity 111 and the second cavity 112 can rotate in opposite directions.

[0043] The prior art window filter rod discloses that the forming paper wrapping the cavity is transparent forming paper, and a through hole is formed on the transparent forming paper of part of the window filter rod, so that during smoking, the airflow can flow between the cavity and the external environment through the through hole, and disturb the flow of the particles in the cavity, thereby improving the visual effect and interest during smoking of the cigarette. However, the single appearance is easy to cause aesthetic fatigue of consumers over a long period of time, cannot meet the increasing demand of consumers, and cannot better meet the smoking experience of consumers at different levels.

[0044] The cigarette filter rod 100 provided by the embodiment adopts a double-layer cavity, a thin composite sheet with good air permeability (i.e., the air-permeable separator 12) is added between the two cavities, and the through holes 40 on the first transparent forming paper 21 and the second transparent forming paper 22 are respectively designed to have different dense directions. According to Bernoulli effect, airflow difference in different directions can be achieved during the smoking process of the cigarette, and the particulate matter 30 in the two cavities can rotate in different directions. The rotation of the particulate matter 30 in different directions not only brings better novelty experience and visual impact to consumers, but also better meets the needs of consumers and the smoking experience of consumers at different levels, and can better reduce tar and nicotine in smoke and improve filtering effect.

[0045] In a specific embodiment, in order to better reduce costs, three through holes 40 are respectively formed on the first transparent forming paper 21 and the second transparent forming paper 22. On one side of the forming paper 20, two through holes 40 are formed on the first transparent forming paper 21, and one through hole 40 is formed on the second transparent forming paper 22. On the other side of the forming paper 20, one through hole 40 is formed on the first transparent forming paper 21, and two through holes 40 are formed on the second transparent forming paper 22. Of course, in other embodiments, the number of through holes 40 formed on the first transparent forming paper 21 and the second transparent forming paper 22 can also be selected according to actual needs, as long as airflow can flow in opposite directions in the first cavity 111 and the second cavity 112.

[0046] In an embodiment, during the smoking process of the cigarette, the airflow flows from the second cavity 112 to the first cavity 111. During the smoking process of the cigarette, the airflow velocity in the first cavity 111 and the second cavity 112 is greater than that of the external environment, external air flows into the first cavity 111 and the second cavity 112 through the through holes 40, the airflow velocity is large at the dense part of the through holes 40, and the airflow velocity is small at the sparse part of the through holes 40. According to Bernoulli effect, the airflow pressure is large at the sparse part of the through holes 40, and the airflow pressure is small at the dense part of the through holes 40, so that a pressure difference from large to small is formed from the sparse part of the through holes 40 to the dense part of the through holes 40, thereby realizing the rotation of the particulate matter 30 in the first cavity 111 and the second cavity 112 from the sparse part of the through holes 40 to the dense part of the through holes 40. Since the sparse degree of the through holes 40 of the first transparent forming paper 21 and the second transparent forming paper 22 is just opposite, the airflow directions in the first cavity 111 and the second cavity 112 are also just opposite, so that the particulate matter 30 can rotate in different directions during the smoking process of the cigarette.

[0047] It can be understood that, in order to avoid the particles 30 from falling, the aperture of the through hole 40 should be smaller than the maximum diameter of the particles 30.

[0048] Preferably, in an embodiment, a plurality of the cavities 11 are formed in the filter rod body 10, and all the cavities 11 are sequentially and spaced apart along the axial direction of the filter rod body 10. Specifically, the particles 30 and the first transparent formed paper 21 and the second transparent formed paper 22 are arranged in each of the cavities 11. Through this structure, the needs of consumers can be better met, and consumers have more choices.

[0049] Preferably, in an embodiment, the air-permeable partition 12 and the filter rod body 10 are made of the same material, that is, the air-permeable partition 12 and the filter rod body 10 are made of the same filter material, so that the smoke circulation and smoke filtering effect of the whole cigarette filter rod 100 can be better guaranteed. Specifically, in an embodiment, the filter rod body 10 can be made of a two-acetic acid fiber bundle.

[0050] Preferably, in an embodiment, the particles 30 are one of a tobacco flavoring particle, a tobacco moisture-retaining particle, a tobacco tar-reducing particle, a tobacco flavoring and moisture-retaining particle, and a tobacco flavoring and tar-reducing particle, so that the functional effect of the cigarette filter rod 100 can be better guaranteed, and different consumers' needs can be met according to actual needs.

[0051] Preferably, in an embodiment, the particles 30 are activated carbon particles or coffee particles, so that the adsorption effect or taste of the cigarette filter rod 100 can be better improved.

[0052] The cigarette filter rod 100 can improve the smoke quality of cigarettes, reduce the irritability of smoke, and realize airflow difference in opposite directions by non-uniform punching direction. During the smoking process of the cigarette, the particles 30 in the first cavity 111 and the second cavity 112 rotate in opposite directions, and the particles 30 can better adsorb tar, nicotine and other particulate matter in the smoke during the rotation and collision process.

[0053] Meanwhile, the embodiment also provides a cigarette including a tobacco segment and the cigarette filter rod 100 connected with the tobacco segment.

[0054] Meanwhile, the embodiment also provides a forming method of the cigarette filter rod 100, which includes the following steps:

[0055] S1, cutting a raw rod into short rods, and arranging the short rods with a certain interval between adjacent two short rods; wherein the interval is at least two.

[0056] The whole original rod is cut to form a plurality of short rods, and the short rods are arranged separately, so that the two adjacent short rods are spaced apart.

[0059] S4, perforating the shaped paper 20, and the perforation density of the adjacent two transparent shaped papers is opposite.

[0060] That is, along the same direction, the density of the perforation of one of the transparent shaped papers gradually increases, and the density of the perforation of the other transparent shaped paper gradually decreases.

[0061] S5, wrapping the short rods and the particles 30 with the perforated shaped paper to form a rod.

[0062] The cigarette filter rod 100 can be formed by the forming method.

[0063] Preferably, in an embodiment, the original rod is cut by a filter rod compounding machine in step S1, so that the cutting efficiency and effect can be improved.

[0064] Preferably, in an embodiment, the shaped paper 20 is perforated by a mechanical perforating device in step S4, so that the perforating efficiency and effect can be improved. Specifically, the mechanical perforating device can be a laser perforating machine.

[0065] Preferably, in an embodiment, after step S5, the method further comprises:
