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, commercially available aerosol generating products mostly 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 is used to heat the aerosol generating product containing the aerosol generating matrix. During the heating process, the aerosol generating matrix does not burn. When the aerosol generating matrix is ​​heated to a temperature range sufficient to release aerosols, it releases aerosols for the user to inhale.

[0003] However, 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 experience. Moreover, the condensate and soot produced by the aerosol generating matrix in existing aerosol-generating products after heating are prone to leaking into the inhalation device, causing contamination of the inhalation device and even damage to the inhalation device in severe cases. 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. The housing has an air inlet and an air outlet. The air outlet has an air outlet that communicates with the cavity. The air inlet has a bottom wall that closes the cavity. An air inlet hole that communicates with the cavity is provided on the side wall of the air inlet.

[0007] An aerosol generating matrix is ​​fixedly disposed inside the housing and 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, and the cavity is connected to the air inlet.

[0008] 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 opened at the end of the first part away from the second part, the bottom wall is located at the end of the second part away from the first part, and the air inlet is opened on the second part;

[0009] 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.

[0010] In one embodiment, the air inlet is located on the side wall of the housing near the bottom wall, and there are multiple air inlets, which are spaced apart circumferentially along the housing.

[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 airways are multiple and are arranged in a ring-like space.

[0013] In one embodiment, the housing has a sealing edge at one end edge where the air outlet is located. The sealing edge is bent from the edge of the air outlet toward the central axis of the housing and attached to the edge of the aerosol generating matrix. The sealing edge has at least two edges, and all the sealing edges are spaced apart along the circumference of the housing.

[0014] In one embodiment, the sealing edge extends radially toward the central axis of the housing, and 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.

[0015] In one embodiment, the air inlet is configured as a plurality of micropores arranged in an array at intervals.

[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, the suction device being used to heat the aerosol generation article to generate an aerosol.

[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. This allows for several advantages: First, during the suction interval, a larger amount of outside air can enter the cavity through the air inlet and be temporarily stored within it, facilitating uniform airflow distribution. Furthermore, during each suction cycle, a large amount of air can carry a significant amount of aerosol into the mouth, thereby increasing the aerosol extraction rate and improving the user's suction experience. Second, the cavity can store condensate and soot produced after the aerosol generating matrix is ​​heated, preventing leakage of condensate and soot into the suction device and avoiding contamination.

[0035] 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 heat source heats the heating chamber, allowing heat to be transferred to the aerosol generating product. After the aerosol generating matrix inside the aerosol generating product is heated to a certain temperature, it releases aerosols that can be inhaled by the user.

[0036] 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.

[0037] 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 a ring at intervals, so that there are more extraction channels to extract aerosols, thereby enabling users to extract a larger amount of aerosols during aspiration.

[0038] 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 housing 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 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 bottom wall 105 of the housing 100 are spaced apart, so that a cavity 107 is formed in the receiving cavity 101 that is spaced apart from the air outlet 104 and communicates with the air inlet hole 106.

[0039] Thus, during the suction process, such as Figure 3 As shown by the straight line with arrows, the airflow enters the cavity 107 through the air inlet 106, gathers, and then is distributed to each airway 201 to mix with the aerosol. Finally, it is inhaled into the user's mouth through the air outlet 104. It is easy to see that by forming the cavity 107, during the suction interval, more outside air can enter the cavity 107 through the air inlet 106 and be temporarily stored in the cavity 107, which facilitates the uniform distribution of airflow. 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.

[0040] Furthermore, to prevent the aerosol generation matrix 200 from approaching the bottom wall 105 of the housing 100, and to ensure that the cavity 107 is always present, in one embodiment, such as Figure 3 and Figure 5 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, a bottom wall 105 is located at the end of the second part 120 away from the first part 110, and 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 108. The aerosol generating matrix 200 is disposed in the first part 110 and abuts against the limiting step 108, so as to limit the aerosol generating matrix 200 and prevent the aerosol generating matrix 200 from approaching the bottom wall 105. Therefore, the cavity 107 is formed in the second part 120.

[0041] 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 is 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 105.

[0042] In a more specific location where the air inlet 106 is located, in one embodiment, the air inlet 106 is located on the side wall of the housing 100 near the bottom wall 105, and there are multiple air inlets 106. The multiple air inlets 106 are arranged at intervals along the circumference of the housing 100. With the above arrangement, on the one hand, outside air can enter the cavity 107 evenly from each air inlet 106, which is more conducive to the aerosol generating matrix 200 extracting aerosols, and can ensure that the amount of aerosols drawn in each puff is relatively consistent, thereby improving the consistency of aerosol release. On the other hand, the cavity 107 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.

[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] Furthermore, 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 it from falling out of the housing 100 from the outlet end, such as... Figure 6 and Figure 7 As shown, a sealing edge 300 is integrally connected to one end edge of the housing 100 where an air outlet 104 is provided. The sealing edge 300 extends from the edge of the air outlet 104 toward the central axis of the housing 100. Figure 6 and Figure 7 The dotted line shown is bent (i.e., facing towards) Figure 6 (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.

[0045] 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 8 As shown, in Figure 8 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.

[0046] Optionally, such as Figure 6 and Figure 7As 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.

[0047] 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.

[0048] 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.

[0049] The aerosol generating article 10 provided in this application is assembled by first loading a solid-state molded aerosol generating matrix 200 into the receiving cavity 101 of the housing 100. The limiting step 108 inside the housing 100 is used to limit the aerosol generating matrix 200 to restrict its movement toward the bottom wall 105 of the housing 100, so that a cavity 107 is formed in the receiving cavity 101 of the housing 100. After the aerosol generating matrix 200 is loaded into the housing 100, the sealing edge 300 is pressed 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 article 10.

[0050] Furthermore, regarding the materials of the shell 100 and the edge sealing 300, the shell 100 and the edge sealing 300 can be made of a metal material with good thermal conductivity. Preferably, the shell 100 and the edge sealing 300 are made of aluminum foil. This allows heat to be transferred quickly from the periphery of the shell 100 to the center inside the shell 100 when the aerosol generating product 10 is heated, thereby enabling the aerosol generating matrix 200 to heat up quickly and generate aerosol. Also, because aluminum foil is tough, it easily deforms under certain pressure, making it easy for the edge sealing 300 to bend and adhere to the top of the aerosol generating matrix 200 when subjected to compressive force after the aerosol generating matrix 200 is assembled into the shell 100. Of course, the material of the shell 100 is not limited to metal; it can also be any other high thermal conductivity material, which is not limited here.

[0051] 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.

[0052] 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.
