Description

Technical Field

[0001] The utility model relates to the technical field of tobacco, in particular to a cigarette. Background Art

[0002] With the development of the tobacco industry, cavity filter rods have been developed to increase the fun and visual novelty of cigarettes. Different patterns are set on the sidewalls and cross-sections of cavity filter rods to enhance the fun effect. However, due to the low draw resistance of cavity filter rods, the tar filtration effect is weakened. At the same time, when air flows through the cavity of the cavity filter rod, the short flow path reduces the cooling effect. As a result, cavity filter rods cannot achieve both fun and applicability. Utility Model Content

[0003] The purpose of the utility model is to provide a cigarette which can ensure the interest of the cigarette and improve the tar reduction effect and the temperature reduction effect.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] Cigarettes, including;

[0006] A filter rod assembly comprising a filter rod body and a transparent shaping paper, wherein a tar reduction cavity is provided inside the filter rod body and extends axially through the filter rod body, a plurality of ventilation holes and a plurality of baffles are provided at intervals on the sidewalls of the tar reduction cavity, and the transparent shaping paper is wrapped around the outer peripheral wall of the filter rod body;

[0007] The tobacco segment is coaxially connected to one end of the filter rod body and communicated with the tar reduction cavity.

[0008] As a further technical solution, the plurality of baffles are arranged perpendicular to the axis of the filter rod body, and along the axial direction of the filter rod body, the cross-sectional area of ​​the plurality of baffles is smaller than the cross-sectional area of ​​the coke reduction cavity.

[0009] As a further technical solution, the plurality of baffles are arranged in one-to-one correspondence with the plurality of ventilation holes.

[0010] As a further technical solution, along the axial direction of the filter rod body, the distribution tracks of the plurality of baffles are arranged in a spiral shape.

[0011] As a further technical solution, the baffle is integrally formed with the filter rod body.

[0012] As a further technical solution, the filter rod assembly further comprises a proximal lip member, the proximal lip member being connected to a side of the filter rod body facing away from the tobacco segment and being coaxially arranged with the filter rod body;

[0013] Alternatively, the end of the filter rod body facing away from the tobacco segment is arranged as a proximal lip portion.

[0014] As a further technical solution, a plurality of grooves are arranged at intervals on one side of the transparent shaping paper close to the filter rod body.

[0015] As a further technical solution, the cigarette further comprises luminescent particles, which are arranged between the transparent shaping paper and the filter rod body or in the tar reduction cavity.

[0016] As a further technical solution, the tobacco segment is configured as a tobacco cut piece or an aerosol production piece.

[0017] As a further technical solution, the cigarette further comprises transparent tipping paper, and the transparent tipping paper is wrapped around the filter rod assembly and the outer peripheral wall of the tobacco segment.

[0018] Compared with the existing technology, the cigarette provided by the utility model has the following technical advantages:

[0019] Because the sidewalls of the tar reduction chamber are provided with multiple ventilation holes at intervals, and the transparent shaping paper is wrapped around the outer wall of the filter rod body, during smoking, when the smoke reaches the tar reduction chamber, some of the smoke is emitted from the multiple ventilation holes into the space between the transparent shaping paper and the filter rod body, thereby increasing interest and visual novelty by observing the movement of the smoke between the transparent shaping paper and the filter rod body, as well as the smoke flow through the multiple ventilation holes. Because the sidewalls of the tar reduction chamber are provided with multiple baffles at intervals, when the smoke reaches the tar reduction chamber, as the smoke flows, aerosol components in the smoke collide and impact with the multiple baffles, thereby intercepting a portion of the smoke aerosol in the tar reduction chamber, achieving the technical effect of tar reduction. Furthermore, as the smoke flows in the tar reduction chamber, the collision and impact between the multiple baffles and the smoke causes the flow path of the smoke in the tar reduction chamber to continuously change. During this process, the contact area and contact time of the smoke in the tar reduction chamber are increased, thereby enhancing the cooling effect of the smoke as it flows through the filter rod assembly. During the entire process, multiple ventilation holes and multiple baffles are set up to take into account the fun of smoking, the tar reduction effect and the cooling effect.

[0030] Combine Figures 1 to 4As shown, the cigarette provided in this embodiment can ensure enjoyment while improving both the tar reduction and cooling effects. Specifically, the cigarette includes a filter rod assembly and a tobacco segment 200. The filter rod assembly includes a filter rod body 100 and a transparent shaping paper. The filter rod body 100 is provided with a tar reduction cavity 110 therein. The tar reduction cavity 110 extends axially through the filter rod body 100. The sidewalls of the tar reduction cavity 110 are provided with a plurality of ventilation holes 111 and a plurality of baffles 112 at intervals. The transparent shaping paper is wrapped around the outer wall of the filter rod body 100. The tobacco segment 200 is coaxially connected to one end of the filter rod body 100 and communicates with the tar reduction cavity 110.

[0031] Since multiple ventilation holes 111 are arranged at intervals on the side walls of the tar reduction chamber 110, and the transparent forming paper is wrapped around the outer wall of the filter rod body 100, during the smoking process, after the smoke reaches the tar reduction chamber 110, part of the smoke is emitted from the multiple ventilation holes 111 to between the transparent forming paper and the filter rod body 100, thereby increasing the interest and visual novelty by observing the movement of the smoke between the transparent forming paper and the filter rod body 100 and the smoke flow in the multiple ventilation holes 111. Since a plurality of baffles 112 are arranged at intervals on the side walls of the tar reduction chamber 110, when the smoke reaches the tar reduction chamber 110, as the smoke flows, the aerosol components in the smoke collide and impact with the plurality of baffles 112, so that a portion of the aerosol in the smoke is intercepted in the tar reduction chamber 110, achieving the technical effect of tar reduction. In addition, as the smoke flows in the tar reduction chamber 110, as the plurality of baffles 112 collide and impact with the smoke, the flow path of the smoke in the tar reduction chamber 110 continuously changes. In this process, the contact area and contact time of the smoke in the tar reduction chamber 110 increase, thereby improving the cooling effect of the smoke when it flows through the filter rod assembly. Throughout the entire process, by providing a plurality of ventilation holes 111 and a plurality of baffles 112, the fun of smoking, the tar reduction effect, and the cooling effect are taken into account.

[0032] In other embodiments, according to actual needs, the outer wall of the filter rod body 100 can be wrapped with ordinary wrapping paper or high-transparency wrapping paper.

[0033] Furthermore, the multiple baffles 112 are positioned perpendicular to the axis of the filter rod body 100 to further enhance the interception of aerosol components in the smoke and to enhance the tar reduction effect when the multiple baffles 112 collide and impact. Along the axial direction of the filter rod body 100, the cross-sectional area of ​​the multiple baffles 112 is smaller than the cross-sectional area of ​​the tar reduction chamber 110 to ensure the fluidity of the smoke within the tar reduction chamber 110 and prevent the smoke from being completely blocked in the tar reduction chamber 110, thereby ensuring the cooling and tar reduction effects on the smoke flowing through the filter rod assembly.

[0034] Furthermore, multiple baffles 112 are arranged in a one-to-one correspondence with multiple ventilation holes 111. When the smoke flows to the ventilation holes 111, part of the smoke is emitted between the transparent forming paper and the filter rod body 100, and the other part of the smoke forms a vortex at the ventilation holes 111 under the cooperation of the ventilation holes 111 and the corresponding baffles 112, thereby slowing down the flow speed of the smoke, so as to further enhance the cooling effect and tar reduction effect of the smoke flowing through the filter rod assembly.

[0035] Furthermore, along the axial direction of the filter rod body 100, the distribution trajectory of multiple baffles 112 is arranged in a spiral shape. When the flue gas reaches the tar reduction chamber 110, the flue gas flows in a spiral shape along the multiple baffles 112 to further increase the contact area and contact time of the flue gas in the tar reduction chamber 110.

[0036] Preferably, the baffle 112 is integrally formed with the filter rod body 100. Specifically, the sidewall of the filter rod body 100 corresponding to the ventilation hole 111 is folded toward the interior of the tar reduction chamber 110 to form the baffle 112. This reduces the processing difficulty while also allowing a portion of the filter rod body 100 to be directly bent to form the baffle 112, thereby lowering production costs.

[0037] Specifically, if Figure 3 As shown, when the cigarette is used as a traditional cigarette, the tobacco segment 200 can be set as a tobacco piece, and the end of the filter rod body 100 away from the tobacco segment 200 is set as the lip portion; when smoking, the smoke flows directly out from the lip portion and passes through the filter rod body 100 to achieve the technical purpose of reducing tar. Figure 4 As shown, when the cigarette is used as a heated cigarette, the tobacco segment 200 is configured as an aerosol-generating element. The filter assembly also includes a lip proximal member 120, which is connected to the side of the filter body 100 facing away from the tobacco segment 200 and is coaxially arranged with the filter body 100. During smoking, smoke flows directly from the filter body 100 and then flows through the lip proximal member 120, thereby further extending the smoke flow path and enhancing the cooling and tar reduction effects of the smoke. In this embodiment, the lip proximal member 120 is provided with acetate fiber tow or other fiber tow.

[0038] Preferably, a plurality of grooves are arranged at intervals on one side of the transparent shaping paper close to the filter rod body 100. When part of the smoke is emitted from the plurality of ventilation holes 111 to between the transparent shaping paper and the filter rod body 100, the smoke between the transparent shaping paper and the filter rod body 100 is further diffused between the plurality of grooves, thereby facilitating the dilution, cooling and tar reduction of the smoke in the area.

[0039] Furthermore, the cigarette also includes luminescent particles, which are disposed between the transparent forming paper and the filter rod body 100 or within the tar reduction cavity 110. During smoking, by observing the luminescent particles, one can experience the dynamic changes in the particles' color and experience the changes during inhalation, making the cigarette's appearance more recognizable and increasing its differentiation, interest, and visual novelty. The luminescent particles can be directly fabricated using existing technologies and will not be further described here.

[0040] Preferably, the cigarette also includes transparent tipping paper, which wraps around the outer wall of the filter rod assembly and tobacco segment 200. The transparent tipping paper protects the filter rod assembly and tobacco segment 200 to ensure the smoking effect of the cigarette, while also allowing the flow of smoke in the filter rod assembly to be observed through the transparent tipping paper. Furthermore, patterns can be drawn on the transparent tipping paper to enhance the fun.

[0041] In addition, the filter rod assembly provided in this embodiment can be used in conjunction with the tobacco segment 200, or can be used as a separate component.

[0042] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
