[0030] refer to Figure 1 and Figure 2 Embodiment 1 of this application proposes a heated non-combustible tobacco cartridge 100, comprising a shell 10 and an aerosol generating matrix 20. The shell 10 includes a hollow housing 110 arranged along the axial direction Z, and annular sealing edges 120 extending radially along the Z direction are respectively provided at both ends of the housing 110. The aerosol generating matrix 20 is placed inside the shell, and an axial air passage 210 is provided inside the aerosol generating matrix 20. Both ends of the aerosol generating matrix 20 are limited by the annular sealing edges 120.

[0031] The shell 110 is a hollow tubular structure with a circular cross-section, but it is not limited to a circle; it can also be rectangular, polygonal, or irregular in shape. In this application, for ease of understanding and description, axial and radial directions are used to represent two perpendicular directions.

[0032] Optionally, the aerosol generating matrix 20 is a one-piece solid form, such as a mixture containing nicotine or tobacco extract, or nicotine-free.

[0033] The cross-sectional shape of the aerosol generating matrix 20 matches the cross-sectional shape of the inner wall of the shell 110. Air passages 210 within the aerosol generating matrix 20 extend through both ends of the aerosol generating matrix 20. When the heated non-combustible tobacco cartridge 100 is used, the airflow direction within the aerosol generating matrix 20 can be as follows: Figure 2 As indicated by the middle arrow P, the airflow enters the air passage 210 from the lower end of the aerosol generating matrix 20 and exits the air passage 210 from the upper end of the aerosol generating matrix 20.

[0034] The annular sealing edges 120 at both ends of the housing 110 are identical in shape and size. In other embodiments, the length and / or shape of the annular sealing edges 120 may be different. Optionally, the annular sealing edges 120 are integrally formed with the housing 110.

[0035] The annular sealing edge 120 extends radially along the housing 110. The annular sealing edges 120 at both ends of the housing 110 respectively limit the two ends of the aerosol generating matrix 20, so that the housing 110 and the annular sealing edge 120 together limit the aerosol generating matrix 20.

[0036] The following is combined Figure 3 and Figure 4 The assembly process of the heated non-combustible smoke cartridge 100 in Example 1 is briefly described below.

[0037] refer to Figure 3 Middle stage (1) and Figure 4 The system provides an intermediate 30 and an aerosol generating matrix 20. The intermediate 30 includes a shell 110, and both ends of the shell 110 are provided with annular sealing edges 120 along the axial direction P of the shell 110. The intermediate 30 differs from the outer shell 10 in the heated non-combustible tobacco cartridge 100 in that the annular sealing edges 120 in the intermediate 30 are arranged along the axial direction of the shell 110, and the annular sealing edges 120 are not bent radially inward.

[0038] refer to Figure 3 In the intermediate stage (2), the aerosol generating matrix 20 is inserted axially into the housing 110 from one end. (Reference) Figure 3 In the middle stage (3), the annular sealing edges 120 at both ends of the shell 110 are pressed from both sides in the directions indicated by arrows F1 and F2 to form the sealing edges, so that the annular sealing edges 120 press against the aerosol generating matrix 20, thus obtaining stage (3), that is... Figure 1 The heated non-combustible tobacco cartridge 100 shown.

[0039] The heated non-combustible tobacco cartridge 100 of this application has annular sealing edges 120 at both ends in the axial direction to limit the aerosol generating matrix 20. Both ends can be normally inserted into the atomizing device, making it easy for users to operate.

[0040] In some embodiments, the outer shell 10 is made of metal foil. Using a metal shell to enclose and position the aerosol generating matrix 20 results in rapid heat transfer and consequently, rapid smoke emission. Furthermore, the outer shell 10 has a simple structure; assembly with the aerosol generating matrix 20 only requires inserting the aerosol generating matrix 20 into the shell 110 and then sealing it with the annular sealing edge 120, making assembly simple and cost-effective.

[0041] Optionally, the outer casing 10 is made of aluminum foil. Aluminum foil does not release harmful substances at high temperatures, thus avoiding harm to the user.

[0042] refer to Figure 1 Optionally, the annular seal 120 completely avoids the airway 210. Specifically, the annular seal 120 surrounds the airway 210, but does not obscure the airway 210. (Reference) Figure 2 In this embodiment, the airway 210 includes multiple sub-channels 211, and the annular seal 120 avoids all the sub-channels 211, so that the annular seal 120 will not affect the air intake and exhaust of the aerosol generating matrix 20.

[0043] In other embodiments, the annular sealing edge 120 may also cover part of the air passage 210. In this case, the annular sealing edge 120 may be provided with air holes corresponding to the air passage 210, thereby allowing airflow to pass through.

[0044] refer to Figure 1 , Figure 3 , Figure 4 The housing 110 has at least two annular sealing edges 120 at both ends in the axial direction. The at least two annular sealing edges 120 are spaced apart in the circumferential direction of the housing 110, and a notch 130 is provided between adjacent annular sealing edges 120.

[0045] In this embodiment, the annular sealing edges 120 at both ends of the housing 110 respectively form two notches 130. (See reference) Figure 3 After the aerosol generating matrix 20 is placed into the shell 110, it can squeeze the annular sealing edge 120 at the notch 130, causing the annular sealing edge 120 to bend inward toward the shell 110, thereby completing the sealing.

[0046] In other embodiments, the notch 130 may be formed only on the annular sealing edge 120 at one end of the housing 110.

[0047] Further, refer to Figure 1 and Figure 4 Each end of the housing 110 is provided with two annular sealing edges 120, which are symmetrically arranged about the center line of the housing 110 in the axial direction. Each annular sealing edge 120 at each end forms two notches 130, and the two notches 130 at each end are symmetrically arranged about the center line of the housing 110 in the axial direction.

[0048] by Figure 1 Taking the upper annular sealing edge 120 of the middle shell 110 as an example, the two annular sealing edges 120 at the upper end form two notches 130, which are evenly distributed around the circumference of the shell 110. The lower annular sealing edge 120 of the shell 110 is similarly arranged. Furthermore, the upper and lower annular sealing edges 120 are structurally symmetrical.

[0049] Using the methods described above, when inserting the aerosol generating matrix 20 into the housing 110, there is no need to consider foolproof insertion. In other words, the aerosol generating matrix 20 can be inserted from either end of the housing 110, making assembly convenient.

[0050] refer to Figures 5 to 7 In the second embodiment of this application, the heated non-combustible tobacco cartridge 100 has plugs 40 at both ends of the outer shell. The plugs 40 are embedded in the shell 110 and located between the corresponding annular sealing edge 120 and the aerosol generating matrix 20. The plugs 40 have a venting structure 410. The venting structure 410 connects the air passage 210 with the space outside the shell.

[0051] In this embodiment, the assembly method of the heated non-combustible tobacco cartridge 100 is briefly described as follows.

[0052] refer to Figure 8 In the intermediate stage (1), an intermediate 30 and an aerosol generating matrix 20 are provided. The intermediate 30 includes a shell 110, and both ends of the shell 110 are provided with annular sealing edges 120 along the axial direction of the shell 110. The intermediate 30 differs from the outer shell 10 in the heated non-combustible tobacco cartridge 100 in that the annular sealing edges 120 in the intermediate 30 are arranged along the axial direction of the shell 110 and have not been bent radially inward. The aerosol generating matrix 20 is inserted axially into the shell 110 from one end of the shell 110.

[0053] refer to Figure 8 In the middle stage (2), two plugs 40 are provided, which are inserted into both ends of the housing 110 and respectively abut against the aerosol generating matrix 20.

[0054] refer to Figure 8 In the middle stage (3), the annular seals at both ends of the housing 110 are formed by pressing them together from both sides in the directions indicated by arrows F1 and F2, so that the annular seals 120 press against the plugs 40, thus obtaining stage (4), which is... Figure 5 The heated non-combustible tobacco cartridge 100 shown.

[0055] In this embodiment, plugs 40 are added to both ends of the outer shell. When sealing the edges, the plugs 40 have the function of protecting the aerosol generation matrix 20, avoiding the risk of the aerosol generation matrix 20 being crushed, and improving the production yield.

[0056] refer to Figure 6 In some embodiments, the airway 210 includes multiple sub-channels 211. The venting structure 410 is a vent hole penetrating the plug 40, and the hole diameter is smaller than the hole diameter of the sub-channels 211. The plug 40 has a cavity 420 on the side facing the aerosol generating matrix 20, and the cavity 420 communicates with the venting structure 410 and with all the sub-channels 211.

[0057] like Figure 6 As shown, all sub-channels 211 are connected to the cavity 420 and then to the outside through the venting structure 410. This ensures that, on the one hand, airflow from each sub-channel 211 can flow out during use; on the other hand, it ensures that the airflow from each sub-channel 211 flows out through the venting structure 410. Since the pore size of the venting structure 410 is smaller than that of the sub-channels 211, it prevents the aerosol-generating matrix 20 powder from overflowing during use, ensuring the smoking device remains clean and requires no cleaning.

[0058] In addition, the plug 40 can also be used to collect and store the condensate produced when the cartridge is heated and cooled. The vent hole has a small diameter, and by using capillary action, the condensate in the cavity 420 will not flow out from the vent hole.

[0059] Furthermore, along the axial direction and away from the aerosol generating matrix 20, the cavity 420 is a gradually narrowing conical segment 421. The airflow in the sub-channel 211 flows towards the permeable structure 410 under the guidance of the conical segment 421 (see...). Figure 6 (in the direction of the middle arrow P), thus concentrating the flow of smoke and improving the smoking experience.

[0060] When using the aerosol generating matrix 20 in the atomizing device, refer to... Figure 6 When the heat source of the atomizing device generates heat, the heat is transferred through the outer casing 10 to the aerosol generating matrix 20, causing the aerosol generating matrix 20 to be heated to a certain temperature and then release aerosol. As the user begins to inhale, outside air can then... Figure 6 The lower end of the inner shell 10 enters the outer shell 10, mixes with the aerosol inside the outer shell 10, and is then sucked into the user's mouth from the upper end of the outer shell 10 under suction. In the above process, the cavity 420 in the plug 40 below the aerosol generating matrix 20 collects the gas flowing in from the outside and buffers the airflow. At the same time, the lower cavity 420 also collects carbon ash residue and coolant generated during the suction process; the cavity 420 in the plug 40 above the aerosol generating matrix 20 plays the role of mixing aerosol and outside air.

[0061] In some embodiments, the plug 40 is an elastic element. This configuration allows the plug 40 to be easily inserted into the housing 110.

[0062] Optionally, the plug 40 can be made of silicone or fiber cotton. It's easy to understand that the lower limit of the temperature resistance of the silicone or fiber cotton should not be lower than the operating temperature of the cartridge during use. Generally, the operating temperature should not exceed 350℃.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
