[0001] The invention relates to the field of novel tobacco cigarettes, in particular to a method for manufacturing a cooling composite filter rod. Background Art

[0002] The hardware in the existing tobacco cigarette filter is a hollowed-out cylinder that guides smoke through the hollowed-out part. However, this method of guiding smoke through the large through hole in the middle will gather hot air, so that when the tobacco is heated but not burned, extremely high-temperature hot air will be generated and transferred to the mouthpiece. When the human mouth touches the mouthpiece, the mouth will feel hot, causing personal safety issues and leaving a bad experience for the user.

[0003] In addition, the existing tobacco cigarette filter tip needs to be compounded multiple times to complete the assembly of a cigarette filter tip, which has too many steps and complicated processes, resulting in high costs and low production efficiency. Summary of the invention

[0029] Specifically, a cooling composite filter rod unit 2 is a cigarette filter, and at least one air channel 4 for guiding smoke is formed at the junction of the fixing member 3 and the inner wall of the circular tube 1. That is, a plurality of grooves (air channels 4) are provided on the edges around the fixing member 3 for guiding smoke.

[0030] In this embodiment, the round tube 1 is a cylindrical paper tube with a hollow interior. In other embodiments, a plastic tube can also be used as the round tube 1 of the present invention.

[0031] By opening a plurality of air channels 4 for guiding smoke around the edge of the fixture 3, smoke is prevented from being concentrated in the middle of the fixture 3, and hot smoke is effectively guided, thereby reducing the temperature of the cigarette filter and smoke without affecting the quality of the smoke, providing a comfortable taste and an excellent experience.

[0036] In this embodiment, the filter cotton segment 7 is a filter cotton segment 7 made of acetate cotton, PLA cotton or other materials.

[0037] Furthermore, the cooling layer 6 includes a plurality of cooling particles 8 , and the fixture 3 is provided with a receiving portion 9 and a through hole 10 connected to the receiving portion 9 . The receiving portion 9 can receive the cooling particles 8 , and the cooling particles 8 cannot pass through the through hole 10 .

[0038] In this embodiment, the cooling particles 8 further cool the smoke, thereby further reducing the temperature of the smoke filter, and the cooling particles 8 will not affect the quality of the smoke, further improving the user experience.

[0039] Furthermore, the outer diameter of the fixture 3 is equal to the inner diameter of the circular tube 1 .

[0040] Furthermore, the outer diameter of the filter cotton segment 7 is equal to the inner diameter of the circular tube 1 .

[0041] In this embodiment, the outer diameter of the fixing member 3 and the outer diameter of the filter cotton segment 7 are equal to the inner diameter of the circular tube 1 , so that the fixing member 3 and the filter cotton segment 7 just fit the circular tube 1 .

[0042] The present invention also provides a manufacturing process of a cooling composite filter rod, and the manufacturing process of the cooling composite filter rod comprises the following steps:

[0043] Step 1: prepare a round tube 1, a fixing 3, cooling particles 8, and a filter cotton segment 7 respectively;

[0044] Step 2: Push the fixing piece 3 into the circular tube 1 from the first end thereof for a certain distance, so that a receiving chamber 5 is formed in the circular tube 1 at the certain distance;

[0049] Step 7: Push the fixture 3 from the second end of the round tube 1 so that the fixture 3 contacts the cooling particles 8;

[0050] Step 8: A distance is reserved from the second end of the circular tube 1 to the position of the fixing piece 3 to form a receiving chamber 5, thereby completing the assembly of another cooling composite filter rod unit 2 adjacent to the cooling composite filter rod unit 2 of step 4;

[0051] Step 9: Cut the axis centers of two adjacent cooling composite filter rod units 2 to form two cooling composite filter rod units 2 with completely identical structures, namely, cigarette filters.

[0052] Furthermore, the fixture 3 is pushed in from the first end of the circular tube 1 so that the inner wall of the circular tube 1 wraps the fixture 3 , thereby forming at least one air channel 4 for guiding the flue gas at the junction of the fixture 3 and the inner wall of the circular tube 1 .
