Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco technology, and in particular to a filter rod and a cigarette. Background Technology
[0002] Cigarettes consist of tobacco shreds and a filter. With the development of the cigarette industry, the function of the filter is no longer limited to filtering and absorbing harmful substances in the smoke; it has been given many other functions. For example, by adding various functional particles, powders, liquids, and other materials to the filter, functions such as enhancing flavor and improving appearance are achieved, greatly enriching the diversity of cigarette filters and improving the playability and visual appeal of the filter and cigarette during smoking.
[0003] However, some cigarettes on the market currently have smokers who report that the smoke flow rate is too fast, the smoke is not rich or full-bodied, and the smoking experience is not strong enough. Utility Model Content
[0004] The purpose of this invention is to address the lack of a filter rod structure in the existing technology that can reduce the smoke flow rate and make the inhalation flavor richer. This invention provides a filter rod that can increase the collision between the smoke and the first and second spiral swirling elements, thereby reducing the smoke flow rate, causing the smoke to condense before flowing out, and thus increasing the richness and fullness of the smoke, making the inhalation flavor richer.
[0005] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a filter rod, comprising:
[0006] Filter cartridges are used to filter flue gas;
[0007] Formed paper is used to wrap the filter element;
[0008] The first helical swirling element has a helical shaft that extends along the axial direction of the filter element and is located inside the filter element.
[0009] The second spiral swirling element has a spiral shaft that extends along the axial direction of the filter element. The second spiral swirling element is located inside the filter element, and the second spiral swirling element and the first spiral swirling element are arranged to intersect and spiral each other.
[0010] Using the above technical solution, the filter element has a suction end and a connection end at its two ends, with the smoke flowing from the connection end to the suction end. Because the first and second helical swirling elements are arranged in a crisscrossing pattern inside the filter element, the smoke will come into contact with and collide with these elements during its flow, resulting in a decrease in smoke velocity and achieving a swirling range extension effect. In this process, the smoke is condensed and enriched, thereby increasing the richness and fullness of the smoke's aroma, and ultimately improving the smoking experience.
[0011] Optionally, the first and second helical swirl elements have the same direction of rotation and are arranged to spiral in an intersecting manner.
[0012] Optionally, the pitch, inner diameter, and outer diameter of the first and second helical swirling elements are the same; along the axial direction of the filter element, the projections of the first and second helical swirling elements completely overlap.
[0013] Optionally, the pitch of the first and second helical swirl elements is 10 mm, the inner diameter is 3 mm, and the outer diameter is 5 mm.
[0014] Optionally, the two ends of the first helical swirling element are flush with the upper surface and the lower surface of the filter element, respectively, and the two ends of the second helical swirling element are flush with the upper surface and the lower surface of the filter element, respectively.
[0015] Optionally, both the first and second helical swirl elements have quadrilateral cross-sectional shapes.
[0016] Optionally, the outer walls of both the first and second helical swirl elements are in contact with the inner wall of the forming paper.
[0017] Optionally, both the first and second helical swirl elements are made of biodegradable materials.
[0018] Optionally, the first and second helical swirl elements are made of one or more of photosensitive resin, silicone, or plastic.
[0019] This application also discloses a cigarette, including the above-mentioned filter rod and cigarette segment, wherein the cigarette segment is connected to the filter rod. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0032] Figure 1 This diagram shows the structure of the cigarette in an embodiment of the present invention. Figure 2 This diagram illustrates the structure of the first and second helical vortex components in an embodiment of the present invention. (Reference) Figure 1 The filter rod 100 provided in this application embodiment includes: a filter element (not shown in the figure), a forming paper 130, a first spiral swirling element 140, and a second spiral swirling element 150. The filter element is generally cylindrical, and along the axial direction (e.g., ... Figure 1 Extending in the X direction (as shown). The filter element is made of filter materials such as cellulose acetate and is used to filter harmful substances in the smoke. The end of the filter element away from the mouthpiece is the connecting end 110, used to connect to the cigarette stick section 200. The end of the filter element closer to the mouthpiece is the suction end 120, used for user inhalation. Forming paper 130 wraps around the outside of the filter element, forming a support structure for the filter rod 100, giving the filter rod 100 a certain degree of roundness and rigidity. (Reference) Figure 2 The spiral shaft of the first spiral vortex element 140 (e.g.) Figure 2 (As shown by the dashed line L) Extending axially along the filter element, the first helical swirling element 140 is disposed inside the filter element. The helical shaft of the second helical swirling element 150 (as shown by the dashed line L) Figure 2 (As shown by the dashed line L) Extending along the axial direction of the filter element, the second spiral swirling element 150 is disposed inside the filter element, and the second spiral swirling element 150 and the first spiral swirling element 140 are arranged to intersect and spiral each other.
[0033] Using the above technical solution, the smoke flows from the connecting end 110 to the suction end 120. Since the first spiral swirling element 140 and the second spiral swirling element 150 are arranged in a crisscrossing pattern inside the filter element, the smoke will come into contact with and collide with these elements during its flow, resulting in a decrease in smoke velocity and achieving the effect of increasing the range of the swirling smoke. During this process, the smoke is condensed and enriched, thereby increasing the richness and fullness of the smoke aroma and improving the smoking experience.
[0034] According to another specific embodiment of the present invention, the first helical swirl member 140 and the second helical swirl member 150 have the same direction of rotation (e.g., both are left-handed or both are right-handed) and are arranged in a crisscrossing spiral configuration. For example, in this embodiment, as... Figure 2 As shown, the first helical swirl element 140 and the second helical swirl element 150 are both right-handed. In other embodiments, the first helical swirl element 140 and the second helical swirl element 150 may both be left-handed.
[0035] Furthermore, the pitch, inner diameter, and outer diameter of the first helical swirl element 140 and the second helical swirl element 150 are all the same. Preferably, the pitch of both the first helical swirl element 140 and the second helical swirl element 150 is 10 mm, the inner diameter is 3 mm, and the outer diameter is 5 mm.
[0036] Furthermore, Figure 3 This diagram shows an axial view of the first spiral vortex member 140 in an embodiment of the present invention. Figure 4 This diagram shows an axial view of the second spiral vortex member 150 in an embodiment of the present invention. Figure 5 Show Figure 1 An axial schematic diagram. (See attached diagram.) Figure 3 , Figure 4 and Figure 5 As shown, along the axial direction of the filter element, the projections of the first helical swirling element 140 and the second helical swirling element 150 completely coincide. For example, as... Figure 3 , Figure 4 and Figure 5 As shown, the projections of the first helical swirling element 140 and the second helical swirling element 150 along the axial direction form a circle. That is to say, the structures of the first helical swirling element 140 and the second helical swirling element 150 are exactly the same.
[0037] It should be noted that this application does not limit the number of spirals in the first spiral vortex 140 or the number of spirals in the second spiral vortex 150. Those skilled in the art can flexibly adjust them according to actual needs to match different suction flow rates and suction tastes.
[0038] Furthermore, in this embodiment, reference continues to be made to... Figure 1 The two ends of the first helical swirling element 140 are flush with the upper and lower surfaces of the filter element, respectively, and the two ends of the second helical swirling element 150 are also flush with the upper and lower surfaces of the filter element, respectively. In other words, the two ends of the first helical swirling element 140 and the two ends of the second helical swirling element 150 are aligned axially. In other embodiments, those skilled in the art can choose whether the first helical swirling element 140 and the second helical swirling element 150 are flush with the upper and lower surfaces of the filter element according to actual needs.
[0039] Furthermore, in this embodiment, reference is made to... Figure 5 The outer walls of the first spiral swirling element 140 and the second spiral swirling element 150 both penetrate the outer surface of the filter element and come into contact with the inner wall of the forming paper 130 (which has a certain thickness). In other embodiments, the outer walls of the first spiral swirling element 140 and the second spiral swirling element 150 may not come into contact with the inner wall of the forming paper 130.
[0040] Optionally, the cross-sectional shape of both the first helical swirl member 140 and the second helical swirl member 150 is quadrilateral, such as a square, rectangle, or trapezoid. For example, the cross-sectional shape of both the first helical swirl member 140 and the second helical swirl member 150 is trapezoidal. In other embodiments, the cross-sectional shape of the first helical swirl member 140 and the second helical swirl member 150 may be rectangular.
[0041] According to another specific embodiment of the present invention, both the first helical vortex element 140 and the second helical vortex element 150 are made of biodegradable materials. Further, both the first helical vortex element 140 and the second helical vortex element 150 are made of food-grade biodegradable materials. Optionally, the first helical vortex element 140 and the second helical vortex element 150 are made of one or more of photosensitive resin, silicone, or plastic. For example, the first helical vortex element 140 and the second helical vortex element 150 are 3D printed from polylactic acid (PLA) photosensitive resin, possessing both strength and biodegradability.
[0042] According to another specific embodiment of this utility model, such as Figure 1 As shown, a cigarette is also disclosed, comprising a filter rod 100 and a cigarette segment 200 as described in any of the above embodiments. The cigarette segment 200 and the filter rod 100 are fixed together by a splicing paper (not shown in the figure), forming a complete cigarette structure. Because this cigarette is equipped with a filter rod 100 having a first spiral swirling element 140 and a second spiral swirling element 150, the aroma is richer and fuller, the taste is more intense, and the smoking experience is improved.
[0043] The filter rod 100 and cigarette provided by this utility model can increase the collision between the smoke and the first spiral swirling element 140 and the second spiral swirling element 150 when the smoker is smoking, thereby reducing the flow rate of the smoke, causing the smoke to condense before flowing out, thereby increasing the richness and fullness of the smoke and making the smoking taste more intense.
[0044] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
