Abstract
Description
Technical Field
[0001] This application relates to the field of electronic atomization technology, and in particular to an aerosol substrate component and an electronic atomization system. Background Technology
[0002] Electronic atomizing devices, as a substitute for traditional cigarettes, are characterized by being tar-free, ash-free, and flame-free, effectively avoiding the various harmful substances produced when traditional cigarettes are lit. Some electronic atomizing devices include a cartridge and a heating structure. The cartridge stores the aerosol-generating matrix, and the heating structure heats the cartridge, causing the stored aerosol-generating matrix to atomize and form an inhalable aerosol.
[0003] To reduce user costs, e-cigarette devices with cartridges are typically designed with replaceable cartridges. However, these devices usually only hold one cartridge, requiring users to carry not only the device itself but also multiple spare cartridges, needing to replace each cartridge after use, which is inconvenient. Furthermore, replacing a used cartridge with a new one results in resource waste and environmental problems. To address this, related technologies have proposed e-cigarette devices with multiple cartridges; however, flavor mixing between multiple cartridges can negatively impact the user's vaping experience. Utility Model Content
[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes an aerosol substrate assembly and an electronic atomization system. In the aerosol substrate assembly, a barrier is provided between two adjacent aerosol substrate segments. When a target aerosol substrate segment is heated, the barrier can prevent the target aerosol substrate segment from transferring heat to adjacent aerosol substrate segments. On the one hand, this improves the heat utilization rate, thereby increasing the heating efficiency of the target aerosol substrate segment. On the other hand, it helps prevent aerosol substrate segments other than the target aerosol substrate segment from being heated and forming aerosols, thus improving the problem of cross-contamination of flavors between different aerosol substrate segments. Simultaneously, it helps prevent the premature consumption of aerosol substrate segments other than the target aerosol substrate segment.

When this aerosol substrate segment is used up, the position of the aerosol substrate assembly relative to the heating area within the electronic atomization device is changed again, thereby selecting another aerosol substrate segment within the housing as the target aerosol substrate segment for heating. A barrier is provided between two adjacent aerosol substrate segments. When the target aerosol substrate segment is heated, the barrier can prevent the target aerosol substrate segment from transferring heat to the adjacent aerosol substrate segment. On the one hand, this improves heat utilization, thereby increasing the heating efficiency of the target aerosol substrate segment.

[0041] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.
[0042] Reference Figures 1 to 8 An aerosol substrate assembly according to an embodiment of this application includes a housing, at least two independent aerosol substrate segments 100, and at least one barrier member 200.
[0043] Specifically, the aerosol substrate segment 100 is disposed within the housing and is used to be heated to form an aerosol. The barrier 200 is disposed within the housing and is arranged along the long axis of the housing. The barrier 200 divides the space within the housing into at least two independent receiving cavities 310. Each aerosol substrate segment 100 is disposed in each receiving cavity 310 in a corresponding manner. The receiving cavity 310 with the aerosol substrate segment 100 is configured to allow airflow to pass through.
[0044] In use, the aerosol substrate assembly is assembled into the electronic atomizing device. The electronic atomizing device has a heating chamber, and a local area within the heating chamber forms a heating zone. The electronic atomizing device also has an air inlet channel and an air outlet channel connecting the heating zone. By changing the position of the aerosol substrate assembly relative to the heating zone of the electronic atomizing device, one aerosol substrate segment 100 within the housing is selected as the target aerosol substrate segment 100 for heating to generate an aerosol that can be inhaled by the user through the air outlet channel of the electronic atomizing device. When the aerosol substrate segment 100 is used up, the position of the aerosol substrate assembly relative to the heating zone of the electronic atomizing device is changed again to select another aerosol substrate segment 100 within the housing as the target aerosol substrate segment 100 for heating. In this embodiment, a barrier 200 is provided between two adjacent aerosol substrate segments 100. When the target aerosol substrate segment 100 is heated, the barrier 200 can prevent the target aerosol substrate segment 100 from transferring heat to the adjacent aerosol substrate segment 100. On the one hand, it can improve the heat utilization rate, thereby improving the heating efficiency of the target aerosol substrate segment 100. On the other hand, it can prevent aerosol substrate segments 100 other than the target aerosol substrate segment 100 from being heated and forming aerosols, thereby improving the problem of cross-contamination of odors between different aerosol substrate segments 100. At the same time, it can prevent aerosol substrate segments 100 other than the target aerosol substrate segment 100 from being consumed prematurely.
[0045] It should be noted that the aerosol substrate segment 100 in this application can be made from tobacco or contain nicotine salts. Specifically, the aerosol substrate segment 100 in this application can be made from granular, filamentous, sheet-like, or paste-like tobacco, or it can be made from solid tobacco.
[0046] Reference Figures 1 to 3 as well as Figures 5 to 8 In some embodiments, the housing includes an outer shell 320 and an inner shell 330, both of which are cylindrical structures open at both ends. The inner shell 330 is disposed inside the outer shell 320, and the axis of the outer shell 320 and the axis of the inner shell 330 are collinear. The inner diameter of the outer shell 320 is larger than the outer diameter of the inner shell 330, so that there is an annular gap between the inner wall of the outer shell 320 and the outer wall of the inner shell 330. A barrier 200 is disposed in the gap to separate at least two receiving cavities 310 open at both ends. The receiving cavities 310 have openings at both ends, allowing airflow to pass through. In use, a heating structure can be provided on the outer side of the outer shell 320 to heat the target aerosol substrate segment 100, and a heating structure can also be provided on the inner side of the inner shell 330 to heat the target aerosol substrate segment 100, thereby improving the heating efficiency of the target aerosol substrate segment 100, and consequently improving the smoke emission efficiency and smoke volume of the aerosol substrate segment 100. In addition, by providing the inner shell 330, it is beneficial to reduce the radial dimension of the aerosol substrate segment 100 along the shell, thereby improving the heating efficiency of the central region of the target aerosol substrate segment 100.
[0047] In some embodiments, the thickness of both the outer shell 320 and the inner shell 330 is less than 0.1 mm to reduce the heat resistance of the outer shell 320 and the inner shell 330, so that the heating structure disposed on the outer side of the outer shell 320 and the inner side of the inner shell 330 can heat the target aerosol substrate segment 100 more efficiently.
[0048] In some embodiments, the thermal conductivity of both the outer shell 320 and the inner shell 330 is greater than 50 W / (m·K) to ensure the thermal conductivity of the outer shell 320 and the inner shell 330, so that the heating structure disposed on the outer side of the outer shell 320 and the inner side of the inner shell 330 can heat the target aerosol substrate segment 100 more efficiently.
[0049] Specifically, the outer shell 320 and the inner shell 330 can be made of ordinary cigarette paper or cellulose, or of course, metal (such as aluminum foil) or other highly thermally conductive materials, without limitation.
[0050] In some embodiments, the thermal conductivity of the barrier 200 is less than 0.5 W / (m·K) to ensure the heat resistance of the barrier 200.
[0051] Specifically, the barrier 200 is made of fiber paper or other low thermal conductivity materials.
[0052] Reference Figure 4 In some other embodiments, the housing includes an outer shell 320, which is a cylindrical structure open at both ends. A barrier 200 is disposed within the outer shell 320 to separate at least two receiving cavities 310 open at both ends, allowing airflow to pass through. Thus, the aforementioned inner shell 330 is unnecessary; during use, a heating structure is only required on the outside of the outer shell 320 to heat the target aerosol substrate segment 100, simplifying the product structure and thus reducing product costs.
[0053] In some embodiments, sealing structures are provided at both ends of the receiving cavity 310. These sealing structures prevent the aerosol substrate segment 100 from detaching from the receiving cavity 310, and are configured to allow airflow. By providing sealing structures at both ends of the receiving cavity 310, the aerosol substrate segment 100 can be prevented from detaching from the receiving cavity 310 during the transport of the aerosol substrate assembly and during the assembly of the aerosol substrate assembly into the main body of the electronic atomizing device. The sealing structures are configured to allow airflow, thus enabling airflow to pass through the receiving cavity 310.
[0054] In some embodiments, the sealing structure is embedded or sleeved at the end opening of the receiving cavity 310. Specifically, the sealing structure may be a plug.
[0055] It should be noted that in some other embodiments, the sealing structure may also be integrally formed into the housing.
[0056] In some embodiments, the sealing structure is provided with vents for air permeation, so that airflow can pass through the sealing structure.
[0057] It should be noted that in some other embodiments, the sealing structure can also be made of breathable or porous materials, in which case there is no need to deliberately set breathable holes for ventilation on the sealing structure.
[0058] Reference Figure 5 In some embodiments, the barrier 200 has a first cavity 210 for heat insulation, which is beneficial to further improve the heat insulation effect of the barrier 200.
[0059] Specifically, the first cavity 210 can be filled with gas, such as air. Of course, the first cavity 210 can also be evacuated, which is not limited here.
[0060] Reference Figure 5In some embodiments, at least one end of the barrier 200 is an open structure for connecting the first cavity 210 with the outside atmosphere, so that air in the outside atmosphere can automatically fill the first cavity 210, that is, there is no need to deliberately fill the first cavity 210 with air.
[0061] In some embodiments, a second cavity for heat insulation is formed between the side of the aerosol substrate segment 100 facing the barrier member 200 and the barrier member 200. The heat insulation effect of the barrier member 200 is further improved by using the air filled in the second cavity.
[0062] Reference Figure 6 In some embodiments, the aerosol substrate segment 100 is an integral solid tobacco, and the interior of the aerosol substrate segment 100 is provided with a through hole 110 for airflow to pass through, so that the airflow formed when the user inhales can flow through the heated target aerosol substrate segment 100, thereby delivering the aerosol formed by the heated aerosol substrate segment 100 into the user's mouth.
[0063] Reference Figure 7 In some other embodiments, the aerosol substrate segment 100 is an integral solid tobacco, and the side of the aerosol substrate segment 100 is provided with a through groove 120 for airflow to pass through, so that the airflow formed when the user inhales can flow through the heated target aerosol substrate segment 100, thereby delivering the aerosol formed by the heated aerosol substrate segment 100 into the user's mouth.
[0064] Reference Figure 8 In some other embodiments, the aerosol substrate segment 100 is an integral solid tobacco, and the inner shell 330 is provided with a vent 331 corresponding to each receiving cavity 310. The interior of the aerosol substrate segment 100 is provided with an air passage 130 for guiding airflow to the vent 331, so that the airflow formed when the user inhales can flow through the heated target aerosol substrate segment 100, thereby delivering the aerosol formed by the heated aerosol substrate segment 100 into the user's mouth.
[0065] It should be noted that in some other embodiments, the aerosol substrate segment 100 is an integral solid tobacco, and there is a gap between at least one side of the aerosol substrate segment 100 and the inner wall of the receiving cavity 310, so that the airflow formed when the user inhales can flow through the heated aerosol substrate segment 100. In this case, it is not necessary to deliberately set the above-mentioned through hole 110, through groove 120 or air passage 130.
[0066] It should be noted that when the aerosol substrate segment 100 is made of granular, filamentous, or sheet-like tobacco, the tobacco constituting the aerosol substrate segment 100 is relatively loose, allowing airflow to pass through the interior of the aerosol substrate segment 100. In this case, there is no need to deliberately set the aforementioned through holes 110, through grooves 120, or air channels 130.
[0067] Reference Figures 1 to 7 In some embodiments, all the receiving cavities 310 are arranged in a ring array around the axis of the housing. In use, a fixed heating structure can be set in the main body of the electronic atomizing device, and the aerosol substrate assembly is driven to rotate with the axis of the housing as the rotation center line, so that each aerosol substrate segment 100 can rotate sequentially around the rotation center line of the aerosol substrate assembly to the fixed heating structure as the target aerosol substrate segment 100 for heating.
[0068] Reference Figure 1 and Figure 2 In some embodiments, the end of the barrier 200 is provided with a protruding ridge 220 for engaging with the nozzle of the electronic atomizing device, so as to facilitate the coupling connection between the aerosol substrate assembly and the nozzle of the electronic atomizing device, thereby driving the aerosol substrate assembly to rotate when the nozzle of the electronic atomizing device is rotated.
[0069] Specifically, the aforementioned protruding ridge 220 is trapezoidal, meaning that the aforementioned protruding ridge 220 has a guide slope to facilitate insertion and mating with the nozzle of the electronic atomizing device.
[0070] It should be noted that in some other embodiments, the aforementioned protruding ridge 220 can also be replaced with a groove.
[0071] An electronic atomization system according to an embodiment of this application includes an electronic atomization device and the aforementioned aerosol substrate assembly. The electronic atomization device is used to heat the aerosol substrate assembly to generate an aerosol.
[0072] It should be noted that, since the electronic atomization system of the embodiments of this application includes the above-mentioned aerosol substrate component, the electronic atomization system of the embodiments of this application includes all the technical effects of the above-mentioned aerosol substrate component.
