In the smoking part 40, since the heating component has a certain volume, it will squeeze the smoking part 40, and the smoking part 40 will be squeezed and partially enter the first receiving space 13. The first receiving space 13 is partially or fully filled, thereby preventing the aerosol-generating matrix from being squeezed and causing excessive suction resistance. Specifically, the volume of the first receiving space 13 is 30mm ³ to 35mm ³ , preferably 44mm ³ to 48.5mm ³ , so that the first receiving space 13 provides sufficient movement for the smoking part 40 space, thereby preventing the smoking part 40 from being squeezed and causing the internal gap to become smaller.

In this embodiment, when the preparation of the heat-not-burn cartridge 1 is completed, the heat-not-burn cartridge 1 is in the first state (see Figure 10), and the smoke-generating part 40 is all in the first state. Exterior of Containment Space 13. When the heat-not-burn cartridge 1 is inserted into the smoking article, the heat-not-burn cartridge 1 is in the second state (see Figure 11), and the smoking part 40 partially enters the first receiving space 13. The first receiving space 13 is partially filled or completely filled. It should be noted that in FIG. 10 , the smoke-generating part 40 partially enters the first receiving space 13 and partially fills the first receiving space 13 for illustration, but the smoke-generating part 40 does not enter the first receiving space 13 . The amount of a receiving space 13 is limited. It should be noted that during the preparation process of the heat-not-burn cartridge 1, it is possible that the smoking part 40 partially enters the first receiving space 13 due to processing errors or transportation between processing steps, so that The heat-not-burn cartridge 1 is in the second state. It should be noted that when the heat-not-burn cartridge 1 is not inserted into the smoking article, the smoking part 40 may partially enter the first receiving space 13 due to transportation or external collision, so that the The heat-not-burn cartridge 1 is in the second state. Therefore, the first state only means that the smoke emitting part 40 is outside the first receiving space 13 , and the second state only means that the smoke emitting part 40 partially enters the first receiving space 13 . It can be understood that The first state and the second state do not limit the use state of the heat-not-burn device.

In this embodiment, the outer diameter D2 of the cooling part 10 is larger than the inner diameter D0 of the pipe body 20 , so the cooling part 10 and the pipe body 20 form an interference fit, so that the cooling part 10 can be fixed On the pipe body 20 , the cooling part 10 can be disposed at a preset position of the pipe body 20 and keep the relative position unchanged to form support for the pipe body 20 . Specifically, the outer diameter D2 of the cooling part 10 is: 6.5mm≤D2≤6.8mm, and the inner diameter D0 of the tube body 20 is: 6.4mm≤D0≤6.65mm.

In this embodiment, the filter part 50 is received in the tube body 20 and disposed at the proximal lip end 22 . The filter part 50 is made of food-grade porous fluffy material, such as polylactic acid (PLA). wait. Specifically, the filter part 50 is prepared through an extrusion molding process. In addition, the filter part 50 is spaced apart from the cooling part 10 to form a receiving cavity 60 , and the receiving cavity 60 is used to accommodate aerosol generated by heating the smoke emitting part 40 . The aerosol generated by heating the smoking part 40 is cooled by the cooling part 10 and then flows into the receiving cavity 60 and collects in the receiving cavity 60 . Finally, the aerosol is smoked by the user through the filtering part 50 . Since the aerosol can accumulate in the receiving chamber 60 to form a certain concentration of aerosol, the concentration of the aerosol passing through the filter part 50 can be increased, that is, the concentration of the aerosol inhaled by the user can be increased.

When the heat-not-burn cartridge 1 provided by this application is inserted into a smoking set, the heating component in the smoking set will be inserted into the smoking part 40 and squeeze the smoking part 40. The smoking part 40 After being squeezed, part of the smoke-generating part 40 will enter the first receiving space 13 , thereby preventing the smoke-generating part 40 from being squeezed and causing the internal gap of the smoke-generating part 40 to decrease and thereby increasing the non-burning rate when heated. The draw resistance of cartridge 1. Therefore, the heat-not-burn cartridge 1 provided by the present application can prevent the internal gap of the smoking part 40 from becoming smaller after being inserted into the smoking device, resulting in excessive suction resistance.
