[0024] This invention provides a cigarette filter, comprising a filter component, a connector, and a packaging material. The connector and the filter component are arranged sequentially, and the packaging material covers the outer walls of the connector and the filter component. The connector has an open-ended insertion cavity for inserting a smoking product. A first ventilation hole is provided on the cavity wall of the connector, penetrating the connector. A second ventilation hole is provided on the packaging material corresponding to the first ventilation hole, and the second and first ventilation holes connect the insertion cavity to the outside. After the smoking product is inserted into the insertion cavity, the first ventilation hole can be selectively blocked depending on the insertion depth. The cigarette filter has ventilation holes on both the connector and the packaging material. When the smoking product is inserted into the insertion cavity, the first ventilation hole can be blocked or exposed by adjusting the insertion depth of the smoking product, thereby controlling the airflow and adjusting the draw resistance and tar intake during inhalation. When using the cigarette filter to smoke products, users can freely and flexibly adjust the smoke concentration according to their own needs, satisfying diverse smoking requirements. Furthermore, the cigarette filter has a simple overall structure, does not increase manufacturing costs, and is therefore more cost-effective.

[0025] Please refer to the following: Figures 1 to 3 In one embodiment, a cigarette filter 100 is provided for use in conjunction with a smoking product 200 (cigarette). The cigarette filter 100 is mainly used to solve the problem that existing filters cannot freely adjust the smoke concentration during inhalation, making it difficult to meet diverse usage needs.

[0026] The cigarette filter 100 includes a filter element 10, a connector 20, and a packaging 30. The filter element 10 is mainly used to filter the smoke during the smoking process. The connector 20 is mainly used to connect with the smoking product 200 so that the smoking product 200 can be inserted into the cigarette filter 100. The packaging 30 is mainly used to wrap and connect the filter element 10 and the connector 20 into one unit.

[0027] The insertion component 20 and the filter component 10 are arranged sequentially, and the packaging material 30 covers the outer walls of the insertion component 20 and the filter component 10. The insertion component 20 has an open insertion cavity 21 for inserting the smoking product 200. When the cigarette filter 100 needs to be used, the smoker can insert the filter rod 210 end of the smoking product 200 into the insertion cavity 21, thereby installing the smoking product 200 entirely on the cigarette filter 100. During inhalation, the smoke can be further filtered by the filter component 10, thereby enhancing the filtration effect and reducing the inhalation of harmful substances.

[0028] The insertion component 20 also has a first ventilation hole 22 on its cavity wall, which penetrates the insertion component 20. The cavity wall of the insertion component 20 refers to the wall of the insertion component 20 that forms the insertion cavity 21. The packaging 30 has a second ventilation hole 31 corresponding to the first ventilation hole 22. The second ventilation hole 31 and the first ventilation hole 22 connect the insertion cavity 21 to the outside. After the smoking product 200 is inserted into the insertion cavity 21, it can selectively block the first ventilation hole 22 according to the insertion depth. In other words, in this embodiment, the cigarette filter 100 has a ventilation hole at the cavity where the smoking product 200 is inserted, allowing external airflow to flow into the insertion cavity 21.

[0029] Understandably, the filtration performance of existing filters is fixed. When a smoker uses a filter to inhale smoke-producing products, the effect on smoke concentration is constant and cannot be adjusted by the smoker. Different smokers have different preferences and needs regarding smoke concentration, and existing filter products cannot flexibly adjust the smoke concentration according to individual needs, making it difficult to meet diverse usage requirements.

[0030] The cigarette filter 100 provided in this embodiment has a first ventilation hole 22 on the cavity wall of the insertion component 20 and a second ventilation hole 31 on the packaging 30, thereby forming a channel on the side that allows airflow to enter the insertion cavity 21 from the outside. When the smoker uses the cigarette filter 100, they can adjust the insertion depth of the smoke generator 200 in the insertion cavity 21 to control whether the smoke generator 200 blocks the first ventilation hole 22 (or control the area of ​​the smoke generator 200 blocking the first ventilation hole 22), thereby adjusting the air intake and thus adjusting the suction resistance and tar intake during the smoking process. When using the cigarette filter 100 to smoke the smoke generator 200, the user can freely and flexibly adjust the smoke concentration according to their own needs to meet diverse smoking requirements. The cigarette filter 100 achieves stepless or stepped adjustment of smoke concentration and has a simple and ingenious structure. Smokers can adjust it freely according to their personal preferences without the need for any tools, greatly improving the user experience. Furthermore, this structure requires no additional complex components and does not significantly alter existing production processes, thus resulting in low manufacturing costs and ease of widespread application.

[0031] For example, when the smoking device 200 is inserted deeply, its outer wall partially or completely blocks the first ventilation hole 22, reducing the entry of external air and resulting in a higher smoke concentration during inhalation. When inserted shallowly, the first ventilation hole 22 is partially or completely exposed, increasing the amount of external air entering and diluting the smoke, thereby reducing the smoke concentration. Through this simple insertion and removal adjustment method, the smoker can control the air intake in real time and flexibly during the inhalation process, thereby adjusting the suction resistance and tar intake to meet diverse inhalation needs.

[0032] Specifically, in one embodiment, the cigarette filter 100 is a disposable filter.

[0033] Preferably, in one embodiment, the insertion component 10 and the filter component 20 are arranged sequentially along a first direction. The insertion cavity 21 extends along the first direction; the first ventilation hole 22 penetrates the insertion component 20 along a second direction. The first direction and the second direction are mutually perpendicular. This structure facilitates the entry of external airflow into the insertion cavity 21 and also helps to block the first ventilation hole 22 after the smoke-generating product 200 is inserted. Specifically, in one embodiment, as... Figure 1 As shown, the first direction is axial, while the second direction is radial.

[0034] Specifically, in one embodiment, the end faces of the filter component 10 and the insertion component 20 abut against each other, and their axes coincide, and they are assembled together by being wrapped in the packaging 30. More specifically, in one embodiment, the external cross-sectional contours of the filter component 10 and the insertion component 20 along the direction perpendicular to their axes are identical. In one embodiment, the external cross-sectional contours of both the filter component 10 and the insertion component 20 along the direction perpendicular to their axes can be circular, and both the filter component 10 and the insertion component 20 can have a cylindrical structure. Of course, in other embodiments, the external cross-sectional contours of the filter component 10 and the insertion component 20 along the direction perpendicular to their axes can also be other shapes, which can be selected according to requirements.

[0035] Preferably, in one embodiment, the insertion cavity 21 includes an insertion cavity body 211 and an insertion interface 212 disposed at an end of the insertion cavity body 211, the insertion interface 212 being located at the end away from the filter component 10. The insertion interface 212 has a gradually expanding structure from near the insertion cavity body 211 to away from the insertion cavity body 211. That is, in this embodiment, the insertion port of the insertion cavity 21 has a gradually expanding structure from the inside out. For example, as... Figure 1As shown in the directional angle, from top to bottom, the insertion interface 212 has a gradually widening structure. This structure facilitates the smoker to insert the smoke-generating product 200 into the insertion cavity 21 from the end of the insertion cavity 21.

[0036] Specifically, in one embodiment, the inner diameter of the insertion cavity body 211 is d2, which is between 5 and 10 mm. The inner diameter of the end of the insertion interface 212 away from the filter component 10 is d1, where d1 < d2.

[0037] Preferably, in one embodiment, the insertion cavity 21 is disposed through the insertion component 20 along the first direction, and the insertion component 20 is a hollow tubular structure, that is, the insertion component 20 is specifically a hollow component. The insertion cavity body 211 is a circular cavity, that is, the cross-section of the insertion cavity 21 perpendicular to the axis is circular. It is understood that in the prior art, the smoking product 200 is usually a cylindrical structure, and setting the insertion cavity body 211 as a circular cavity can better adapt to the use of existing smoking products 200. The cavity diameter of the insertion cavity body 211 should be adapted to the diameter of the part of the smoking product 200 to be inserted. After the smoking product 200 is inserted, the circumferential surface of the smoking product 200 will contact the inner surface of the insertion cavity body 211. To ensure that the inner surface of the insertion cavity body 211 is in full contact with the smoking product 200, preferably, in one embodiment, the roundness error of the insertion cavity body is less than 1 mm. More preferably, in one embodiment, the roundness error of the insertion cavity body is less than 0.5 mm.

[0038] Preferably, in one embodiment, the wall thickness of the plug-in component 20 is between 0.03 and 2 mm to balance structural strength and cost.

[0039] It is understood that, assuming the material of the filter element 10 remains consistent, a higher suction resistance results in better filtration. However, excessive suction resistance can lead to difficulty in suction and a poor suction experience. To balance filtration performance and suction experience, preferably, in one embodiment, the suction resistance of the filter element 10 is 1-30 mmH2O. More preferably, in one embodiment, the suction resistance of the filter element 10 is 5-15 mmH2O.

[0040] Specifically, in one embodiment, the filter element 20 is made of fibers, and the filter element 20 may include one or more of polyacetic acid fibers, polypropylene fibers, polylactic acid fibers, and plant fibers.

[0041] Specifically, in one embodiment, the length of the filter element 10 is between 5 and 25 mm.

[0042] Specifically, in one embodiment, the plug-in component 20 may be made of natural or synthetic polymers, such as plant fibers, cellulose acetate, polyethylene, polypropylene, PEEK (polyether ether ketone), and polylactic acid.

[0043] Specifically, in one embodiment, the length of the plug-in component 20 is between 3 and 35 mm. More preferably, in one embodiment, the length of the plug-in component 20 is between 10 and 20 mm.

[0044] It is understood that when the smoke-generating product 200 is fully inserted into the insertion cavity 21, the airflow during inhalation should primarily enter the filter component 10 directly through the smoke-generating product 200. To prevent excessive airflow from entering the filter component 10 through the second ventilation hole 31, the first ventilation hole 22, and the gap between the smoke-generating product 200 and the insertion component 20, preferably, in one embodiment, the distance between the first ventilation hole 22 and the end face of the insertion component 20 near the filter component 10 should be ≥1mm. Specifically, the insertion component 20 includes a first end face 23 located near one end of the filter component 10, the first ventilation hole 22 and the first end face 23 are spaced apart along their length, and the distance between the first ventilation hole 22 and the first end face 23 is not less than 1mm.

[0045] Please refer to the following: Figure 4 Preferably, in one embodiment, the first ventilation holes 22 are arranged in multiple rows along the length direction. This allows the user to adjust the insertion depth of the smoke-generating product 200 to block different rows of the first ventilation holes 22, enabling more flexible adjustment of the smoke concentration and further meeting diverse smoking needs. Each row may have one or more first ventilation holes 22, and the specific number of first ventilation holes 22 in each row can be selected according to actual needs. Correspondingly, each first ventilation hole 22 has a second ventilation hole 31 on its outer side.

[0046] Specifically, in one embodiment, the first ventilation hole 22 can be arranged in two rows, with two first ventilation holes 22 in each row.

[0047] Preferably, in one embodiment, the filter element 10 and / or the connector 20 are provided with a fragrance-enhancing structure. The fragrance-enhancing structure refers to a structure with added flavorings, fragrances, or other substances for aroma enhancement. In other words, in this embodiment, at least one of the filter element 10 and the connector 20 is fragrance-enhanced, thereby further improving the flavor and taste of the smoke during inhalation.

[0048] Please refer to the following: Figure 5Preferably, in one embodiment, the flavoring structure specifically involves adding a flavoring substance to the fiber bundle 11 of the filter element 10. Specifically, the flavoring substance is a fragrance that can be used in the tobacco industry to enhance the smoking flavor. Specifically, in this embodiment, the first ventilation holes 22 can be arranged in a row, with two first ventilation holes 22 in each row.

[0049] Please refer to the following: Figure 6 Preferably, in one embodiment, the fragrance-enhancing structure specifically comprises a breakable fragrance storage unit 12 disposed in the filter component 10. That is, in this embodiment, the fragrance can be stored in the fragrance storage unit 12. When the smoker desires enhanced fragrance, the fragrance storage unit 12 can be broken by applying force, allowing the fragrance to flow into the fiber bundle of the filter component 10, thus enhancing the fragrance. Specifically, in one embodiment, the fragrance storage unit 12 has a spherical structure, specifically a "bursting bead" that can be crushed by force, and stores liquid fragrance within it. Specifically, in this embodiment, the first ventilation holes 22 can be arranged in a row, with two first ventilation holes 22 in each row.

[0050] Please refer to the following: Figure 7 Preferably, in one embodiment, a flavoring material region 24 is provided on the surface of the insertion member 20 that forms the insertion cavity 21. That is, in this embodiment, by applying fragrance to the inner surface of the insertion member 20, the flavoring material region 24 is formed, so that during inhalation, the fragrance can be transferred into the smoke through the inner surface of the insertion member 20, thereby improving the inhalation flavor.

[0051] Preferably, in one embodiment, the fragrance material region 24 extends along the length direction, and the extension distance of the fragrance material region 24 along the length direction is greater than 15% of the length of the plug-in component 20. That is, in this embodiment, the length of the fragrance material region 24 is greater than 15% of the overall length of the plug-in component 20, and the length proportion of the fragrance material region 24 in the plug-in component 20 is greater than 15%, thereby better ensuring the fragrance application effect.

[0052] Specifically, in one embodiment, the fragrance material region 24 extends from the area between the end face of the insertion member 20 near the filter member 10 and the first ventilation hole 22 to the end face away from the filter member 10, and the first ventilation hole 31 is located in the middle of the insertion member 20. Along the length direction of the insertion member 20, the smoking article 200 has three insertion positions in sequence (specifically, a first insertion position 201, a second insertion position 202, and a third insertion position 203). When the smoking product 200 is inserted into the first insertion position 201, the cigarette filter 100 has the functions of aroma application, ventilation and tar reduction, and tar filtration. The airflow has a large contact area and long contact time with the aroma substance area 24, resulting in a rich aroma. When the smoking product 200 is inserted into the second insertion position 202, the cigarette filter 100 has the functions of aroma application and tar filtration. The airflow has a small contact area and short contact time with the aroma substance area 24, resulting in a weaker aroma. When the smoking product 200 is inserted into the third insertion position 203, the cigarette filter 100 only has the function of tar filtration.

[0053] The cigarette filter 100 can adjust the tar content and aroma of the cigarette product 200 during inhalation, and can be applied to different brands of cigarette products 200 according to consumer preferences. The adjustment process is simple. Furthermore, it can be manufactured using existing equipment and processes, resulting in low cost.

[0054] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
