Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to an aerosol generation product and an aerosol generation system. Background Technology

[0002] Currently, most commercially available aerosol generation systems fall into two categories: one type generates aerosols by igniting an aerosol-generating matrix, and the other type generates aerosols through heating without combustion. Taking the heating-without-combustion method as an example, an external heat source heats the aerosol generation product containing the aerosol-generating matrix. During the heating process, the aerosol-generating matrix does not burn. When the matrix is ​​heated to a temperature sufficient to generate aerosols, it releases aerosols for the user to inhale.

[0003] When heating existing aerosol-generating products, there are often problems such as slow aerosol output and a small amount of aerosol inhaled per puff, which seriously affects the inhalation taste. Moreover, the condensate and carbon ash produced by heating the aerosol-generating matrix in existing aerosol-generating products are easy to leak into the inhalation device, causing contamination of the inhalation device, and in severe cases, even damage to the inhalation device. Utility Model Content

[0004] Therefore, it is necessary to provide an aerosol generating product and an aerosol generating system including the aforementioned aerosol generating product, which can avoid the problems mentioned above, in order to address the problems existing in the current aerosol generating products.

[0005] According to one aspect of this application, an aerosol generating article is provided, comprising:

[0006] A housing surrounds a cavity that communicates with the outside of the housing. The housing has an air inlet end and an air outlet end. The air inlet end has a bottom wall that closes the cavity. The outer side of the bottom wall has a groove that extends from the bottom wall toward the air outlet end. An air inlet hole is formed on the groove wall. The housing has an air outlet at the air outlet end that communicates with the cavity. The housing has a sealing edge at the edge where the air outlet is located. The sealing edge bends from the edge of the air outlet toward the central axis of the housing, and the length of the sealing edge in the radial direction of the housing is less than the radius of the housing.

[0007] An aerosol generating matrix is ​​disposed inside the housing. One edge of the aerosol generating matrix is ​​attached to the sealing edge, and the other end is spaced apart from the bottom wall of the housing, so as to form a cavity in the receiving cavity that is spaced apart from the air outlet. The cavity is connected to the air inlet.

[0008] In one embodiment, the groove forms a boss on the inner side of the bottom wall of the shell, the boss being spaced apart from the aerosol generating matrix to form a first cavity located between the boss and the aerosol generating matrix and a second cavity surrounding the boss in the cavity.

[0009] In one embodiment, the groove wall includes a groove bottom wall and a groove side wall surrounding the groove bottom wall, and the air inlet is formed on the groove bottom wall and penetrates the groove bottom wall.

[0010] In one embodiment, the air inlet is configured as a plurality of micropores arranged in an array at intervals.

[0011] In one embodiment, the aerosol generating matrix is ​​a solid form integrally molded, and the aerosol generating matrix has air channels extending through opposite ends of its own axis, one end of the air channel being connected to the air outlet and the other end being connected to the cavity.

[0012] In one embodiment, the sealing edge is provided with an air outlet that penetrates the sealing edge, and the air outlet is aligned with a portion of the air passage.

[0013] In one embodiment, the sealing edge has multiple layers, which are spaced apart along the circumferential direction of the housing at the edge of the air outlet.

[0014] In one embodiment, the housing includes a first part and a second part connected to each other along its own axial direction, the air outlet is located at the end of the first part away from the second part, the bottom wall of the housing is located at the end of the second part away from the first part, and the air inlet is formed on the second part;

[0015] The diameter of the first part is larger than the diameter of the second part, so that the sidewall of the receiving cavity forms a limiting step, and the aerosol generating matrix is ​​disposed in the first part and abuts against the limiting step, so that the cavity is formed in the second part.

[0016] In one embodiment, the housing is made of metal.

[0017] According to another aspect of this application, an aerosol generation system is provided, comprising a suction device and an aerosol generation article as described in any of the above embodiments, the aerosol generation article being mounted on the suction device.

[0018] The aforementioned aerosol generating product, by fixing the aerosol generating matrix inside the shell and spaced apart from the bottom wall of the shell, forms a cavity between the aerosol generating matrix and the bottom wall of the shell, spaced apart from the air outlet. Furthermore, a groove is formed on the outer side of the bottom wall of the shell, extending from the shell wall towards the air outlet. An air inlet is located on the groove wall. During the suction interval, outside air can first accumulate in the groove and then enter the cavity through the air inlet, thus allowing a larger amount of air to accumulate in the cavity. This facilitates a more uniform distribution of airflow into the cavity. Moreover, during each suction, a large amount of air can carry a larger amount of aerosol to the mouth, thereby improving the aerosol extraction rate and enhancing the user's suction experience. On the other hand, the cavity can be used to store condensate and soot produced after the aerosol generating matrix is ​​heated, thus preventing condensate and soot from leaking into the suction device and avoiding contamination.

[0038] One embodiment of this application provides an aerosol generating product and an aerosol generating system. The aerosol generating system includes a suction device and an aerosol generating product. The suction device has a heating chamber, and a heat source is sleeved on the outer wall of the heating chamber. When using the aerosol generating system, the aerosol generating product is inserted into the heating chamber. The heating chamber is heated by the heat source, and the heat can be transferred to the aerosol generating product through the heating chamber, so that the aerosol generating matrix in the aerosol generating product is heated to a certain temperature and then releases aerosol that can be inhaled by the user.

[0039] See Figures 1 to 3 , Figure 1 An explosion diagram of an aerosol-generating article 10 according to an embodiment of this application is shown. Figure 2 A schematic diagram of the appearance of the aerosol-generated article 10 is shown. Figure 3A cross-sectional view of the internal structure of the aerosol generating article 10 is shown. An embodiment of the aerosol generating article 10 provided in this application is a cylindrical capsule-shaped product, comprising a shell 100 and an aerosol generating matrix 200. The shell 100 forms a receiving cavity 101 communicating with the external environment, and the shell 100 has an air inlet end 102 and an air outlet end 103. The aerosol generating matrix 200 is fixedly disposed within the receiving cavity 101 of the shell 100. When the heat source of the suction device generates heat, the heat can be transferred to the aerosol generating matrix 200 through the heating chamber and the shell 100, causing the aerosol generating matrix 200 to be heated to a certain temperature and release aerosols. As the user begins suction, outside air can enter the receiving cavity 101 from the air inlet end 102, mix with the aerosol in the receiving cavity 101, and then be drawn into the user's mouth from the air outlet end 103 under suction.

[0040] In some optional embodiments, the aerosol generating matrix 200 can be in liquid form, stored in a storage bag or container and then fixedly disposed within the housing 100, or it can be in solid form and directly fixedly disposed within the housing 100. Preferably, the aerosol generating matrix 200 is in solid form, for example, it can be a one-piece molded tobacco product or a nicotine-containing product, or it can be tobacco shreds, granules, or sheet tobacco. During inhalation, to facilitate the extraction of aerosols from the aerosol generating matrix 200, such as... Figure 3 As shown, the aerosol generating matrix 200 has air passages 201 extending through its axially opposite ends. Preferably, as shown... Figure 3 As shown, there are multiple airways 201, which are arranged in an array at intervals, so that there are more extraction channels to extract aerosols, thereby enabling the user to extract a larger amount of aerosols during aspiration.

[0041] See Figure 4 , Figure 4 A structural cross-sectional view of the housing 100 is shown, combined with... Figure 2 and Figure 3 As shown, the shell 100 has one open end and one closed end along its own axial direction. Specifically, the air outlet 103 is open and the air inlet 102 is closed. More specifically, the air outlet 103 has an air outlet 104 that communicates with the receiving cavity 101, and the air inlet 102 has a shell bottom wall 105 that closes the receiving cavity 101. The air inlet 102 is provided with an air inlet hole 106 that communicates with the receiving cavity 101. The air inlet hole 106 communicates with one end of the air passage 201 opened by the aerosol generating matrix 200, and the air outlet 104 communicates with the other end of the air passage 201. Preferably, the aerosol generating matrix 200 and the shell bottom wall 105 are spaced apart, so that a cavity 107 is formed in the receiving cavity 101 that is spaced apart from the air outlet 103 and communicates with the air inlet hole 106.

[0042] Better, such as Figure 4 and Figure 5 As shown, the outer side of the bottom wall 105 of the shell (i.e., the side of the bottom wall 105 facing away from the receiving cavity 101) has a groove 1051. The groove 1051 extends from the bottom wall 105 towards the air outlet 103. The air inlet 106 is formed on the groove wall of the groove 1051. Specifically, as shown... Figure 6 As shown, the groove wall of the groove 1051 includes a groove bottom wall 1051a and a groove side wall 1051b surrounding the groove bottom wall 1051a. An air inlet 106 is formed on the groove bottom wall 1051a and penetrates the groove bottom wall 1051a. In the embodiment shown in the figure, there are multiple air inlets 106, and the multiple air inlets 106 are formed in an array at intervals on the groove bottom wall 1051a.

[0043] It should be noted that, for the air inlet 106, when only a single air inlet 106 is provided, the air inlet 106 can be a large hole with a relatively large diameter; the air inlet 106 can also be provided as multiple micro holes arranged in an array at intervals, so as to reduce the harsh whistling suction sound generated by the high-speed airflow formed during the suction process.

[0044] Thus, as Figure 3 As shown by the straight line with arrows, during the suction process, outside air first accumulates in the groove 1051, then enters the cavity 107 from the air inlet 106 and gathers, then flows into each airway 201 to mix with the aerosol, and finally is inhaled into the user's mouth from the air outlet 104. It is easy to see that by forming a cavity 107 between the aerosol generating matrix 200 and the bottom wall 105 of the shell, and by forming a groove 1051 on the outside of the bottom wall 105 of the shell, with the air inlet 106 opened on the groove wall of the groove 1051, outside air can first accumulate in the groove 1051 and enter the cavity 107 together with the air inlet 106 during the suction interval. This allows more air to accumulate in the cavity 107, which is beneficial for the uniform distribution of airflow entering the cavity 107. Moreover, during each suction, a large amount of air can carry a large amount of aerosol and be sucked into the user's mouth, thereby improving the aerosol extraction rate and enhancing the user's suction experience.

[0045] Furthermore, in a preferred embodiment, the housing 100 is formed by stamping a thin metal sheet, optionally, such as... Figure 7 and Figure 8 As shown, the shell 100 is formed by stamping a thin aluminum foil, such that the groove 1051 formed on the outer side of the shell bottom wall 105 forms a boss 108 on the inner side of the shell bottom wall 105 (i.e. the side of the shell bottom wall 105 facing the receiving cavity). The boss 108 is spaced apart from the aerosol generating matrix 200, so that a first cavity 1071 located between the boss 108 and the aerosol generating matrix 200 and a second cavity 1072 surrounding the boss 108 are formed in the cavity 107.

[0046] Through the above design, on the one hand, outside air can enter the first cavity 1071 evenly through each air inlet 106, which is more conducive to the extraction of aerosols by the aerosol generating matrix 200, and can ensure that the amount of aerosol drawn in each puff is relatively consistent, thus improving the consistency of aerosol release. On the other hand, the second cavity 1072 can be used to store the condensate and soot generated after the aerosol generating matrix 200 is heated, thereby preventing the condensate and soot from leaking into the suction device and avoiding contamination of the suction device. Furthermore, because the shell 100 is made of metal, given the good thermal conductivity of metal, when the aerosol generating product 10 is heated, heat can be transferred from the periphery of the shell 100 to the center of the shell 100 at a relatively fast rate, thereby allowing the aerosol generating matrix 200 to be heated and generate aerosols at a relatively fast rate. Of course, the material of the shell 100 is not limited to metal, but can also be any other easily stampable material with good thermal conductivity, which is not limited here.

[0047] It is worth noting that in the above embodiments, the air inlet 106 can also be formed on the side wall 1051b of the groove. When there are multiple air inlets 106, the multiple air inlets 106 can be evenly distributed along the circumferential direction of the groove 1051, which is conducive to the uniform entry of outside air into the cavity 107.

[0048] Furthermore, to prevent the aerosol generation matrix 200 from approaching the bottom wall of the housing 100, thus ensuring the continued existence of the cavity 107, in one embodiment, such as Figure 3 and Figure 8 As shown, the housing 100 includes a first part 110 and a second part 120 connected to each other along its own axial direction. An air outlet 104 is opened at the end of the first part 110 away from the second part 120, and the bottom wall 105 of the housing is located at the end of the second part 120 away from the first part 110. An air inlet 106 is opened on the second part 120. The diameter of the first part 110 is larger than the diameter of the second part 120, so that the side wall of the receiving cavity 101 forms a limiting step 109. The aerosol generating matrix 200 is disposed in the first part 110 and abuts against the limiting step 109, so as to limit the aerosol generating matrix 200 and prevent the aerosol generating matrix 200 from approaching the bottom wall. Therefore, the cavity 107 is formed in the second part 120.

[0049] It is understandable that the diameters of the first part 110 and the second part 120 can also be the same. In this case, the aerosol generating matrix 200 can be fixed to the inner wall of the first part 110 by interference fit or bonding, which can also achieve the purpose of preventing the aerosol generating matrix 200 from moving towards the bottom wall.

[0050] When the aerosol generating matrix 200 is not disposed in the housing 100 by interference fit or bonding, in order to completely fix the aerosol generating matrix 200 and prevent the aerosol generating matrix 200 from falling out of the housing 100 from the outlet end of the housing 100, in one embodiment, such as Figure 9 and Figure 10 As shown, the housing 100 has an integrally formed metal edge seal 300 at one end edge where the vent 104 is located. The edge seal 300 bends from the edge of the vent 104 toward the central axis of the housing 100 (i.e. toward the central axis of the housing 100). Figure 9 (Bent in the direction indicated by the middle arrow) and attached to the aerosol generating matrix 200. In this way, when the aerosol generating matrix 200 is in solid form, it can be ensured that the aerosol generating matrix 200 is fixed and will not fall out of the housing 100.

[0051] It should be noted that, generally, when the aerosol generating matrix 200 is a one-piece molded tobacco product or a nicotine-containing product, the radial dimension of the sealing edge 300 along the shell 100 can be relatively short. In this case, the sealing edge 300 only needs to cover the edge of the aerosol generating matrix 200, without needing to cover the air passage 201, to provide stable support for the aerosol generating matrix 200. However, when the aerosol generating matrix 200 is a more loosely packed item such as tobacco shreds, granules, or flakes, the length of the sealing edge 300 in the radial direction of the shell 100 needs to be adjusted to more tightly adhere to the top of the aerosol generating matrix 200, for example... Figure 11 As shown, in Figure 11 In the embodiment, the sealing edge 300 extends radially toward the central axis of the housing 100, making the length of the seal along the radial direction of the housing 100 longer. This allows for a more secure fixation of the aerosol generating matrix 200. However, since the sealing edge 300 covers part of the air passage 201, in order not to affect the airflow to the outside of the housing 100, the sealing edge 300 is provided with an air outlet 301 that penetrates the sealing edge 300. The air outlet 301 is aligned with the part of the air passage 201 covered by the sealing edge 300, so that the aerosol generating matrix 200 can be securely fixed without affecting the uniform flow of airflow to the outside of the housing 100.

[0052] Optionally, such as Figure 9 and Figure 10 As shown, there are two edge seals 300. The two edge seals 300 are symmetrically arranged with a plane passing through the central axis of the housing 100 as the symmetrical surface. Each edge seal 300 is in the shape of an arc strip. Of course, the number of edge seals 300 is not limited to this. There can also be multiple edge seals 300. Multiple edge seals 300 are arranged at intervals along the circumference of the housing 100 at the edge of the air outlet 104. This is not limited here.

[0053] As can be seen, by fixing the aerosol generating matrix 200 in the housing 100 through the above series of settings, the aerosol generating product 10 does not need to be positioned by a plug at the outlet end 103 of the housing 100. This can prevent the aerosol generating product 10 from releasing harmful substances when heated, thus protecting the user's health.

[0054] It is understood that in other embodiments, the air outlet 103 of the housing 100 may be completely closed to restrict the movement of the aerosol generating matrix 200. However, setting the air outlet 103 of the housing 100 as an open structure and providing the sealing edge 300 makes it easier for the aerosol generating matrix 200 to be assembled into the housing 100, which is obviously a better embodiment.

[0055] The aerosol-generating article 10 provided in this application, during assembly, such as Figure 1 and Figure 3 As shown, firstly, the solid-state aerosol generating matrix 200 is inserted into the receiving cavity 101 of the housing 100. The limiting step 109 within the housing 100 limits the aerosol generating matrix 200, restricting its movement towards the bottom wall of the housing 100, thus forming a cavity 107 within the receiving cavity 101 of the housing 100; Figure 9 and Figure 2 As shown, after the aerosol generating matrix 200 is inserted into the housing 100, the sealing edge 300 is squeezed by an external jig, so that the sealing edge 300 is bent and attached to the top edge of the aerosol generating matrix 200, thereby completing the assembly of the aerosol generating product 10.

[0056] 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.

[0057] 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.
