Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device and 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] In related technologies, to reduce user costs, e-cigarette devices with cartridges are typically configured 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. Utility Model Content

To this end, this application proposes an electronic atomization device and electronic atomization system, which can be configured with at least two independently usable aerosol substrate segments, so that users do not need to carry spare cartridges and frequently replace cartridges, while also helping to improve the problems of resource waste and environmental pollution.

[0056] 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.

[0057] Reference Figures 1 to 15 According to an embodiment of this application, an electronic atomizing device is used to heat an aerosol substrate assembly 200 to generate an aerosol. The aerosol substrate assembly 200 has at least two aerosol substrate segments 210 distributed around a preset center line. The electronic atomizing device includes a device body 100, a heating structure, an air regulating structure, and a driving structure.

[0058] Specifically, the main body 100 of the device has a heating chamber and an air inlet channel 110. The heating chamber is divided into at least two heating areas for heating each aerosol substrate segment 210. The heating structure has at least two heating structures for heating each heating area. The air regulating structure is set inside the main body 100 and has a fixed plate 310 and a rotatable rotating plate 320. The fixed plate 310 is provided with a first vent hole 311 corresponding to each heating area. The rotating plate 320 is used to block the air inlet end of the first vent hole 311. The rotating plate 320 is provided with a second vent hole 321. The second vent hole 321 is used to connect with the first vent hole 311 corresponding to any heating area. The air inlet channel 110 is connected to the second vent hole 321. The driving structure is used to drive the rotating plate 320 to rotate.

[0059] In use, the aerosol substrate assembly 200 is assembled into the heating chamber, with each aerosol substrate segment 210 corresponding to a specific heating area. A drive structure rotates the rotating disk 320, aligning the second vent 321 with the first vent 311 corresponding to one of the heating areas. The aerosol substrate segment 210 corresponding to that heating area is then heated by the corresponding heating structure. When the current aerosol substrate segment 210 is used up, the drive structure rotates the rotating disk 320, aligning the second vent 321 with the first vent 311 corresponding to the next heating area. This eliminates the need for users to carry spare cartridges and frequently replace them, thus reducing resource waste and environmental concerns. Furthermore, each aerosol substrate segment 210 of the aerosol substrate assembly 200 can be selected with different flavors to meet users' diverse taste preferences.

[0060] It should be noted that during use, the aforementioned preset center line is collinear with the rotation center line of the rotating disk 320.

[0061] It should be noted that the aerosol substrate segment 210 in this application is made from tobacco. Specifically, the aerosol substrate segment 210 in this application can be made from granular, filamentous, sheet-like or paste-like tobacco, or it can be made from solid tobacco.

[0062] Reference Figures 1 to 5 In some embodiments, the fixed disk 310 has an air inlet chamber 312, and the rotating disk 320 is rotatably disposed within the air inlet chamber 312. The fixed disk 310 is provided with an air inlet 313 communicating with the air inlet chamber 312, and the air outlet end of the air inlet channel 110 is connected to the air inlet 313. Thus, no matter how the rotating disk 320 rotates, the second vent 321 is always connected to the air outlet end of the air inlet channel 110.

[0063] It should be noted that in some other embodiments, the air intake chamber 312 may also be formed independently inside the device body 100.

[0064] Reference Figure 1 In some embodiments, the main body 100 of the device houses a control device 410, a battery 420, and a drive motor. The control device 410 is electrically connected to both the battery 420 and the drive motor. A rotating shaft 322 is located on the side of the rotating disk 320 facing away from the fixed disk 310. The rotating shaft 322 extends along the rotation center line of the rotating disk 320, and the drive motor is connected to the rotating shaft 322 for transmission. In use, the control device 410 controls the drive motor to drive the rotating disk 320 to rotate.

[0065] Specifically, a switch electrically connected to the control device 410 can be installed on the main body 100 of the device. The switch can be a button or a knob, so that the user can select the timing to drive the rotating disk 320 to rotate through the installed switch.

[0066] Of course, the control device 410 can also automatically control the drive motor to drive the rotating disk 320 to rotate based on the preset usage time or number of suctions of the aerosol substrate segment 210. The control device 410 can also determine that the user has completed suction based on the preset continuous non-suction time or the user's specific suction action after the user stops suctioning, and automatically control the drive motor to drive the rotating disk 320 to rotate based on this.

[0067] Specifically, the control device 410 includes a PCB.

[0068] It should be noted that in some other embodiments, the rotating disk 320 can also be manually driven to rotate via an exposed drive structure (e.g., a knob).

[0069] Reference Figures 6 to 8 In some embodiments, the heating structure includes a first heating element 510 and a second heating element 520. The heating structure also includes a first base 530 and a second base 540. Both the first base 530 and the second base 540 are cylindrical structures open at both ends. The second base 540 is disposed inside the first base 530, and the axis of the first base 530 is collinear with the axis of the second base 540. The inner diameter of the first base 530 is larger than the outer diameter of the second base 540, creating an annular first gap between the inner wall of the first base 530 and the outer wall of the second base 540. This first gap accommodates the aerosol substrate assembly 200. The first heating element 510 is disposed on the inner wall of the first base 530, and the second heating element 520 is disposed on the outer wall of the second base 540. The annular first gap can limit the movement of the aerosol substrate assembly 200, which helps improve the stability and reliability of the aerosol substrate assembly 200 during operation.

[0070] It should be noted that, in some other embodiments, the first heating element 510 may also be disposed on the outer side wall of the first substrate 530 or integrally formed on the first substrate 530.

[0071] It should be noted that, in some other embodiments, the second heating element 520 may also be disposed on the inner sidewall of the second substrate 540 or integrally formed on the second substrate 540.

[0072] Reference Figures 6 to 8In some embodiments, each first heating element 510 has a shared first positive electrode lead 511, each second heating element 520 has a shared second positive electrode lead 521, each first heating element 510 has an independent first negative electrode lead 512, and each second heating element 520 has an independent second negative electrode lead 522; that is, the first heating elements 510 are connected in parallel, and the second heating elements 520 are connected in parallel. In this way, each first heating element 510 and each second heating element 520 can be controlled to heat independently, thereby independently heating the aerosol substrate segment 210 in use.

[0073] Reference Figure 1 and Figure 4 In some embodiments, the electronic atomizing device further includes a mouthpiece 600, which is disposed on the device body 100 and has an air outlet channel 610. At least two independent air vents 620, corresponding one-to-one with each heating area, are provided at the end of the mouthpiece 600 facing the heating chamber. The air vents 620 lead to the air outlet channel 610. The airflow generated during inhalation flows from the air inlet channel 110 to the heating area connected to the second air vent 321, and then through the corresponding air vent 620 to the air outlet channel 610. Thus, when the airflow generated by the user's inhalation flows through the aerosol substrate assembly 200, it only flows through the aerosol substrate segment 210 within the heating area connected to the second air vent 321, thereby further improving the problem of flavor cross-contamination between different aerosol substrate segments 210.

[0074] An electronic atomization system according to an embodiment of this application includes an aerosol substrate assembly 200 and the aforementioned electronic atomization device. The aerosol substrate assembly 200 is housed within a heating chamber and has at least two aerosol substrate segments 210 distributed around a preset centerline. The electronic atomization device is used to heat the aerosol substrate assembly 200 to generate an aerosol.

[0075] It should be noted that since the electronic atomization system of the embodiments of this application includes the above-mentioned electronic atomization device, the electronic atomization system of the embodiments of this application includes all the technical effects of the above-mentioned electronic atomization device.

[0076] Reference Figure 1 , Figure 3 , Figure 4 as well as Figures 9 to 14In some embodiments, the aerosol substrate assembly 200 includes a housing, and a barrier 220 is disposed inside the housing. The barrier 220 divides the space inside the housing into at least two receiving cavities 230 distributed around the rotation center line of the rotating disk 320. Each aerosol substrate segment 210 is disposed in each receiving cavity 230 in a corresponding manner. The receiving cavity 230 disposed of the aerosol substrate segment 210 is configured to allow airflow to pass through. Each first vent 311 is connected to each receiving cavity 230 in a corresponding manner. By separating two adjacent aerosol substrate segments 210 with a barrier 220, it is possible to prevent the aerosol substrate segment 210 in use from transferring heat to the adjacent aerosol substrate segment 210. On the one hand, this can improve the heat utilization rate, thereby improving the heating efficiency of the aerosol substrate segment 210 in use. On the other hand, it can prevent unused aerosol substrate segments 210 from being heated or even forming aerosols, thereby improving the problem of cross-contamination of odors between different aerosol substrate segments 210. At the same time, it can prevent unused aerosol substrate segments 210 from being consumed prematurely.

[0077] Reference Figure 3 , Figure 4 , Figure 9 as well as Figures 11 to 15 In some embodiments, the housing includes an outer shell 240 and an inner shell 250, both of which are cylindrical structures open at both ends. The inner shell 250 is disposed inside the outer shell 240, and the axis of the outer shell 240 is collinear with the axis of the inner shell 250. The inner diameter of the outer shell 240 is larger than the outer diameter of the inner shell 250, so that there is an annular second gap between the inner wall of the outer shell 240 and the outer wall of the inner shell 250. A barrier 220 is disposed in the second gap to separate at least two receiving cavities 230 open at both ends. The heating structure includes a first heating part 510 and a second heating part 520. The first heating part 510 is located outside the outer shell 240, and the second heating part 520 is located inside the inner shell 250. In this way, the heating area of ​​the receiving cavity 230 can be increased, which is beneficial to improving the heating efficiency of the aerosol substrate segment 210, and further beneficial to improving the smoke emission efficiency and smoke emission volume of the aerosol substrate segment 210. In addition, by providing an inner shell 250, it is beneficial to reduce the radial dimension of the aerosol substrate segment 210 along the shell, thereby improving the heating efficiency of the central region of the aerosol substrate segment 210.

[0078] Specifically, the aforementioned preset center line is collinear with the axis of the outer casing 240.

[0079] It should be noted that in some other embodiments, the first heating element 510 can also be directly disposed on the outer side wall of the outer shell 240, and the second heating element 520 can also be directly disposed on the inner side wall of the inner shell 250. In this case, it is not necessary to provide the first base 530 and the second base 540 mentioned above.

[0080] In some embodiments, the thickness of both the outer shell 240 and the inner shell 250 is less than 0.1 mm to reduce the heat resistance of the outer shell 240 and the inner shell 250, so that the heating structure can heat the aerosol substrate segment 210 in use more efficiently.

[0081] In some embodiments, the thermal conductivity of both the outer shell 240 and the inner shell 250 is greater than 50 W / (m·K) to ensure the thermal conductivity of the outer shell 240 and the inner shell 250, so that the heating structure can heat the aerosol substrate segment 210 in use more efficiently.

[0082] Specifically, the outer shell 240 and the inner shell 250 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.

[0083] In some embodiments, the thermal conductivity of the barrier 220 is less than 0.5 W / (m·K) to ensure the heat resistance of the barrier 220.

[0084] Specifically, the barrier 220 is made of fiber paper or other low thermal conductivity materials.

[0085] Reference Figure 10 In some embodiments, the housing includes an outer shell 240, which is a cylindrical structure open at both ends. A barrier 220 is disposed within the outer shell 240 to separate at least two receiving cavities 230 open at both ends. The heating structure includes a first heating element 510 located on the outside of the outer shell 240. Thus, the aforementioned inner shell 250 and second heating element 520 are unnecessary, simplifying the product structure and thereby reducing product costs.

[0086] Specifically, the openings of each receiving cavity 230 near the fixed plate 310 cover each of the first vent holes 311, thereby helping to prevent the airflow from the outlet of the air inlet channel 110 from flowing to the unused aerosol substrate section 210.

[0087] In some embodiments, sealing structures are provided at both ends of the receiving cavity 230. These sealing structures prevent the aerosol substrate segment 210 from detaching from the receiving cavity 230, and are configured to allow airflow. By providing sealing structures at both ends of the receiving cavity 230, the aerosol substrate segment 210 can be prevented from detaching from the receiving cavity 230 during the transport of the aerosol substrate assembly 200 and during the assembly of the aerosol substrate assembly 200 into the device body 100 of the electronic atomizing device. The sealing structures are configured to allow airflow, thus enabling airflow to pass through the receiving cavity 230.

[0088] In some embodiments, the sealing structure is embedded or sleeved at the end opening of the receiving cavity 230. Specifically, the sealing structure may be a plug.

[0089] It should be noted that in some other embodiments, the sealing structure may also be integrally formed into the housing.

[0090] In some embodiments, the sealing structure is provided with vents for air permeation, so that airflow can pass through the sealing structure.

[0091] 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.

[0092] Reference Figure 11 In some embodiments, the barrier 220 has a first cavity 221 for heat insulation, which is beneficial to further improve the heat insulation effect of the barrier 220.

[0093] Specifically, the first cavity 221 can be filled with gas, such as air. Of course, the first cavity 221 can also be evacuated, which is not limited here.

[0094] Reference Figure 11 In some embodiments, at least one end of the barrier 220 is an open structure for connecting the first cavity 221 with the outside atmosphere, so that air in the outside atmosphere can automatically fill the first cavity 221, that is, there is no need to deliberately fill the first cavity 221 with air.

[0095] In some embodiments, a second cavity for heat insulation is formed between the side of the aerosol substrate segment 210 facing the barrier 220 and the barrier 220. The heat insulation effect of the barrier 220 is further improved by using the air filled in the second cavity.

[0096] In some embodiments, the first heating element 510 and the second heating element 520 are both heating films. Of course, the first heating element 510 and the second heating element 520 can also be heating wires, conductive coatings or other heating structures, which are not limited here.

[0097] Reference Figure 13 In some embodiments, the aerosol substrate segment 210 is an integral solid tobacco, and the interior of the aerosol substrate segment 210 is provided with a through hole 211 for airflow to pass through, so that the airflow formed when the user inhales can flow through the aerosol substrate segment 210 in use, thereby delivering the aerosol formed by heating the aerosol substrate segment 210 into the user's mouth.

[0098] Reference Figure 14In some other embodiments, the side of the aerosol substrate segment 210 is provided with a through groove 212 for airflow to pass through, so that the airflow formed when the user inhales can flow through the aerosol substrate segment 210 in use, thereby delivering the aerosol formed by heating the aerosol substrate segment 210 into the user's mouth.

[0099] Reference Figure 15 In some other embodiments, the aerosol substrate segment 210 is an integral solid tobacco. The inner shell 250 is provided with a third vent 251 corresponding to each receiving cavity 230. The interior of the aerosol substrate segment 210 is provided with an air passage 213 for guiding airflow to the third vent 251. The space inside the inner shell 250 is connected to the air outlet channel 610 so that the airflow formed when the user inhales can flow through the aerosol substrate segment 210 in use, thereby delivering the aerosol formed by heating the aerosol substrate segment 210 into the user's mouth.

[0100] It should be noted that in some other embodiments, the aerosol substrate segment 210 is an integral solid tobacco, and at least one side of the aerosol substrate segment 210 has a third gap with the inner wall of the receiving cavity 230, so that the airflow formed when the user inhales can flow through the aerosol substrate segment 210 in use, thereby delivering the aerosol formed by heating the aerosol substrate segment 210 into the user's mouth.

[0101] It should be noted that when the aerosol substrate segment 210 is made of granular, filamentous, or sheet-like tobacco, the tobacco constituting the aerosol substrate segment 210 is relatively loose, allowing airflow to pass through the interior of the aerosol substrate segment 210. In this case, there is no need to deliberately set the aforementioned through holes 211, through grooves 212, or air channels 213.

[0103] It should be noted that in some other embodiments, the first limiting groove 630 may also be provided at the end of the barrier 220 near the nozzle 600, and correspondingly, the first limiting part 222 is provided at the end of the nozzle 600 near the aerosol substrate assembly 200.
