In this embodiment, the cooling tube 40 is spaced apart from the tobacco 30 so that when the cigarette cartridge 1 is inserted into the smoking device, the tobacco 30 has a flowing space to prevent the tobacco 30 from being squeezed and increasing the suction resistance. . Specifically, the distance L2 between the end of the cooling tube 40 away from the second end 12 and adjacent to the tobacco 30 is: 1.5 mm ≤ L2 ≤ 2 mm. Specifically, before the cooling tube 40 is loaded into the outer tube body 10 in step S32, the distance between the end of the cooling tube 40 adjacent to the second end 12 and the second end 12 is x0. For example, by applying external force, the cooling tube 40 moves toward the outer tube body 10 by a distance y=x0+(L0-L1-L2), so that the end of the cooling tube 40 away from the second end 12 is adjacent to the The distance L2 of the tobacco 30 is: 1.5mm≤L2≤2mm. Wherein, L0 is the length of the outer tube body 10: 42mm≤L0≤46mm, and L1 is the length of the part of the tobacco 30 loaded into the outer tube body 10: 15mm≤L1≤18mm.

Please refer to FIG. 10 again. In this embodiment, the ratio of the length L3 of the cooling tube 40 to the length L0 of the outer tube body 10 is: 1:2.65≤L3/L0≤1:2.0.

In this embodiment, the length L3 of the cooling pipe 40 needs to be maintained at an appropriate length. When the length of the outer tube body 10 and the length of the filter element 50 are kept constant, if the length of the cooling tube 40 accounts for the length of the outer tube body 10 is too small, the tobacco 30 will increase When smoking, the combination of the tobacco 30 and the cooling tube 40 will quickly take away heat, thereby reducing the amount of smoke and affecting the smoking experience. If the length of the cooling tube 40 accounts for too much of the length of the outer tube body 10, the filling amount of the tobacco 30 will be reduced, resulting in a relatively short smoking time and insufficient sustainability of the smoking amount. . Therefore, the ratio of the length L3 of the cooling tube 40 to the length L0 of the outer tube body 10 is: 1:2.65≤L3/L0≤1:2.0, which is more suitable. Within this ratio range, the tobacco 30 can be provided with There is enough space to fill enough tobacco 30, thereby increasing the smoking time and duration of smoking, and making the cooling effect better.
