Description

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

[0004] This application aims to address at least one of the technical problems existing in the prior art. 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.

[0005] An electronic atomizing device according to a first aspect embodiment of this application is used to heat a rotatable aerosol substrate assembly to generate an aerosol, the aerosol substrate assembly having at least two aerosol substrate segments distributed around its own rotation center line, the electronic atomizing device comprising:

[0007] A heating structure having a heating structure for heating the heating area;

[0008] The nozzle is rotatably mounted on the main body of the device and can drive the aerosol substrate assembly to rotate, so that each aerosol substrate segment can rotate sequentially around the rotation center line of the aerosol substrate assembly to the heating area. The nozzle has an air outlet channel, and the airflow generated during suction flows from the air inlet channel to the aerosol substrate segment that has rotated to the heating area and flows out through the air outlet channel.

[0009] The electronic atomizing device according to the embodiments of this application has at least the following beneficial effects: During use, the heating structure heats the aerosol substrate segment located in the heating area to form an inhalable aerosol. The airflow generated when the user inhales flows from the inlet channel to the outlet channel. The airflow to the outlet channel passes through the aerosol substrate segment located in the heating area, allowing the aerosol formed by the heated aerosol substrate segment to be delivered into the user's mouth by the airflow generated when the user inhales. When the aerosol substrate segment in the heating area is used up, the mouthpiece can be rotated to drive the aerosol substrate assembly to rotate, thereby rotating the next aerosol substrate segment to the heating area. This eliminates the need for users to carry spare cartridges and frequently replace them, and also helps to reduce resource waste and environmental pollution.

[0010] According to some embodiments of this application, the heating structure includes a first heating element and a second heating element. The heating structure also includes a first base and a second base. Both the first base and the second base are cylindrical structures with openings at both ends.

[0015] According to some embodiments of this application, the aerosol substrate assembly includes a housing, and at least one barrier is disposed within the housing.

Each aerosol substrate segment is correspondingly disposed within each receiving cavity, and the receiving cavity containing the aerosol substrate segment is configured to allow airflow to pass through.

[0016] According to some embodiments of this application, the housing includes an outer shell and an inner shell, both of which are cylindrical structures open at both ends. The inner shell is disposed inside the outer shell, and the axis of the outer shell is collinear with the axis of the inner shell.

[0053] 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.

[0054] Reference Figures 1 to 17 According to an embodiment of this application, an electronic atomizing device is used to heat a rotatable aerosol substrate assembly 200 to generate an aerosol. The aerosol substrate assembly 200 has at least two aerosol substrate segments 210 distributed around its own rotation center line. The electronic atomizing device includes a device body 100, a heating structure, and a nozzle 300.

[0055] Specifically, the device body 100 has a heating chamber 110 inside, and the heating chamber 110 has a preset heating area. The device body 100 is provided with an air inlet channel 120 that connects to the outside atmosphere and leads to the heating area. The heating structure has a heating structure for heating the heating area. The suction nozzle 300 is rotatably disposed on the device body 100 and can drive the aerosol substrate assembly 200 to rotate, so that each aerosol substrate segment 210 can rotate sequentially around the rotation center line of the aerosol substrate assembly 200 to the heating area. The suction nozzle 300 has an air outlet channel 310 that leads to the outside atmosphere. The airflow formed during suction flows from the air inlet channel 120 to the aerosol substrate segment 210 that has rotated to the heating area and flows out through the air outlet channel 310.

[0056] During use, the heating structure heats the aerosol substrate segment 210 located in the heating area to form an inhalable aerosol. The airflow generated when the user inhales flows from the air inlet channel 120 to the air outlet channel 310. This airflow passes through the aerosol substrate segment 210 in the heating area, allowing the aerosol formed by the heated aerosol substrate segment 210 to be delivered into the user's mouth by the airflow generated during inhalation. When the aerosol substrate segment 210 in the heating area is used up, the mouthpiece 300 can be rotated to drive the aerosol substrate assembly 200 to rotate, thus moving the next aerosol substrate segment 210 to the heating area. This eliminates the need for users to carry spare cartridges and frequently replace them, while also reducing resource waste and environmental pollution. Furthermore, each aerosol substrate segment 210 of the aerosol substrate assembly 200 can be selected with different flavors to meet the user's diverse taste preferences.

[0057] 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.

[0058] Reference Figures 4 to 7 In some embodiments, the heating structure includes a first heating element 410 and a second heating element 420. The heating structure also includes a first base 430 and a second base 440. Both the first base 430 and the second base 440 are cylindrical structures open at both ends. The second base 440 is disposed inside the first base 430, and the axis of the first base 430 is collinear with the axis of the second base 440. The inner diameter of the first base 430 is larger than the outer diameter of the second base 440, so that an annular heating cavity 110 is formed between the inner wall of the first base 430 and the outer wall of the second base 440. The first heating element 410 is disposed on the inner wall of the first base 430, and the second heating element 420 is disposed on the outer wall of the second base 440. The first heating element 410 and the second heating element 420 are disposed in corresponding heating areas. The annular heating cavity 110 can limit the aerosol substrate assembly 200, which helps to improve the stability and reliability of the aerosol substrate assembly 200 during operation.

[0059] It should be noted that, in some other embodiments, the first heating element 410 may also be disposed on the outer side wall of the first substrate 430 or integrally formed on the first substrate 430.

[0060] It should be noted that, in some other embodiments, the second heating element 420 may also be disposed on the inner sidewall of the second substrate 440 or integrally formed on the second substrate 440.

[0061] In some embodiments, the electronic atomizing device also includes an unlockable and positioning locking structure for restricting the rotation of the nozzle 300 when either aerosol substrate segment 210 rotates to the heating area, thereby positioning the aerosol substrate segment 210 that has rotated to the heating area in the heating area, which helps to improve the stability and reliability of the aerosol substrate assembly 200 during operation.

[0062] Reference Figures 13 to 17In some embodiments, the locking structure includes a plug-in portion 510 and a plug-in groove 520. An extension portion 130 is provided at the end of the heating chamber 110 away from the nozzle 300, extending towards the nozzle 300. One of the plug-in portion 510 and the plug-in groove 520 is located at the end of the extension 130 near the nozzle 300, and the other is located at the end of the nozzle 300 facing the extension 130. The plug-in portion 510 is inserted into the plug-in groove 520. A mounting hole 511 is provided on the side of the plug-in portion 510, and a positioning portion 530 with a hemispherical end is provided within the mounting hole 511. A compression spring 540 is used to drive the positioning part 530 out of the mounting hole 511. The inner wall of the insertion groove 520 is provided with at least two positioning grooves 521 that correspond one-to-one with each receiving cavity 230. The end of the positioning part 530 facing the inner wall of the insertion groove 520 is hemispherical. The end of the positioning part 530 facing the inner wall of the insertion groove 520 can be inserted into the positioning groove 521 corresponding to any aerosol substrate segment 210 when it rotates to the heating area. The positioning part 530 inserted into the positioning groove 521 can be disengaged from the positioning groove 521 when the suction nozzle 300 rotates. Since the end of the positioning part 530 facing the inner wall of the insertion groove 520 is hemispherical, when the end of the positioning part 530 facing the inner wall of the insertion groove 520 is engaged in any positioning groove 521, continuing to rotate the suction nozzle 300 can force the positioning part 530 to overcome the elastic force of the compression spring 540 and retract into the mounting hole 511, thereby causing the end of the positioning part 530 facing the inner wall of the insertion groove 520 to disengage from the engaged positioning groove 521. Thus, when rotating the suction nozzle 300 to drive the aerosol substrate assembly 200 to rotate, the user can sense whether the aerosol substrate segment 210 that needs to be rotated to the heating area is in place. Simultaneously, the locking and unlocking of the locking structure can be automatically achieved during the rotation of the suction nozzle 300, facilitating operation.

[0063] Specifically, a columnar connecting part 550 is provided inside the mounting hole 511. The connecting part 550 is threaded to the mounting hole 511 or has an interference fit with the mounting hole 511. The connecting part 550 has an assembly hole 551 facing the inner sidewall of the insertion groove 520. The positioning part 530 is slidably disposed in the assembly hole 551. A first limiting step 531 is provided at the end of the positioning part 530 facing away from the inner sidewall of the insertion groove 520. A second limiting step 552 is provided at the opening of the assembly hole 551 to cooperate with the first limiting step 531 for limiting, so as to prevent the positioning part 530 from disengaging from the assembly hole 551. A compression spring 540 is disposed in the assembly hole 551 and acts on the positioning part 530 to drive the positioning part 530 out of the assembly hole 551 and out of the mounting hole 511. In this way, the positioning part 530 can be prevented from disengaging from the mounting hole 511, thereby reducing the assembly difficulty.

[0064] It should be noted that in some other embodiments, the connecting part 550 may not be provided, that is, the positioning part 530 can be disengaged from the mounting hole 511 without obstruction.

[0065] It should be noted that in some other embodiments, the snap-fit ​​structure formed by the positioning part 530 and the positioning groove 521 can also be replaced by a magnetic attraction structure.

[0066] It should be noted that in some other embodiments, the second heating element 420 may also be disposed on the side of the extension 130 corresponding to the heating area, in which case the second substrate 440 described above is not required.

[0067] Reference Figure 16 In some embodiments, the nozzle 300 has at least two independent vents 330 at one end near the aerosol substrate assembly 200, each corresponding to a specific aerosol substrate segment 210. The vents 330 lead to the outlet channel 310. During suction, the airflow flows from the inlet channel 120 to the aerosol substrate segment 210 that has rotated to the heating area, and then through the vents 330 corresponding to that segment to the heating area to the outlet channel 310. This ensures that the airflow during suction only passes through the heated aerosol substrate segment 210 when flowing through the aerosol substrate assembly 200, thereby further improving the problem of odor cross-contamination between different aerosol substrate segments 210.

[0068] 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 rotatably disposed within a heating chamber 110, and the aerosol substrate assembly 200 has at least two aerosol substrate segments 210 distributed around its own rotation center line.

[0069] 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.

[0070] Reference Figure 2 , Figure 3 as well as Figures 8 to 12The aerosol substrate assembly 200 includes a housing, and at least one 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 aerosol substrate assembly 200. Each receiving cavity 230 can rotate sequentially around the rotation center line of the aerosol substrate assembly 200 to the heating area when the aerosol substrate assembly 200 rotates. Each aerosol substrate segment 210 is disposed in each receiving cavity 230 in a corresponding manner. The receiving cavity 230 disposed with the aerosol substrate segment 210 is configured to allow airflow to pass through. By separating two adjacent aerosol substrate segments 210 with a barrier 220, it is possible to prevent the heated aerosol substrate segment 210 from transferring heat to the adjacent aerosol substrate segment 210. On the one hand, this can improve the utilization rate of heat, thereby improving the heating efficiency of the aerosol substrate segment 210 that has rotated to the heating area. On the other hand, it can prevent the aerosol substrate segment 210 that has not rotated to the heating area from being heated or even forming aerosols, thereby improving the problem of cross-contamination of flavors between different aerosol substrate segments 210. At the same time, it can prevent the aerosol substrate segment 210 in the non-heating area from being consumed prematurely.

[0071] Reference Figure 2 , Figure 3 , Figure 8 as well as Figures 10 to 12 In some embodiments, the housing includes an outer shell 240 and an inner shell 250, both of which are cylindrical structures with openings 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 installation space 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 installation space to separate at least two receiving cavities 230 with openings at both ends, allowing airflow to pass through the receiving cavities 230. The heating structure includes a first heating part 410 and a second heating part 420, with the first heating part 410 located outside the outer shell 240 and the second heating part 420 located inside the inner shell 250. This increases the heating area of ​​the cavity 230, thereby improving the heating efficiency of the aerosol substrate section 210, and consequently, improving the smoke extraction efficiency and smoke volume of the aerosol substrate section 210. Furthermore, by providing the inner shell 250, the radial dimension of the aerosol substrate section 210 along the shell can be reduced, thereby improving the heating efficiency of the central region of the aerosol substrate section 210.

[0072] Specifically, both the first heating element 410 and the second heating element 420 are electrically connected to the battery.

[0073] Specifically, the rotation center line of the aerosol substrate assembly 200 is collinear with the axis of the outer shell 240.

[0074] In some embodiments, the outer shell 240 and the inner shell 250 may be made of ordinary cigarette paper or cellulose, or of course, metal or other highly thermally conductive materials, which are not limited herein. When the outer shell 240 and the inner shell 250 are made of ordinary cigarette paper or cellulose, the thickness of both the outer shell 240 and the inner shell 250 is less than 0.1 mm to reduce their heat resistance. When the outer shell 240 and the inner shell 250 are made of metal or other highly thermally conductive materials, the thermal conductivity of both the outer shell 240 and the inner shell 250 is greater than 50 W / (m·K) to ensure their thermal conductivity.

[0075] In some embodiments, the barrier 220 is made of fiber paper or other low thermal conductivity materials, wherein the thermal conductivity of the barrier 220 is less than 0.5 W / (m·K) to ensure the heat insulation effect of the barrier 220.

[0076] Reference Figure 9 In other 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, allowing airflow to pass through. The heating structure includes a first heating element 410 located outside the outer shell 240. Thus, the aforementioned inner shell 250 and second heating element 420 are unnecessary, simplifying the product structure and thereby reducing product costs.

[0077] Specifically, the air outlet of the air inlet channel 120 is located at the end of the heating chamber 110 away from the nozzle 300. The opening of the receiving cavity 230 in the heating area away from the nozzle 300 can cover the air outlet of the air inlet channel 120, thereby preventing the airflow from the air outlet of the air inlet channel 120 from entering other receiving cavities 230.

[0078] It should be noted that in some other embodiments, the air outlet of the air inlet channel 120 can also be located in the area of ​​the heating chamber 110 corresponding to the outer shell 240. Accordingly, an air inlet hole for docking with the air outlet of the air inlet channel 120 can be provided on the outer shell 240.

[0079] It should be noted that in some other embodiments, the end of the suction nozzle 300 near the aerosol substrate assembly 200 may only have one vent 330, and the vent 330 can cover all the receiving cavities 230 accordingly.

[0080] 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.

[0081] 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.

[0082] It should be noted that in some other embodiments, the sealing structure may also be integrally formed into the housing.

[0083] In some embodiments, the sealing structure is provided with vents for air permeation, so that airflow can pass through the sealing structure.

[0084] 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.

[0085] Reference Figure 10 In some embodiments, the barrier 220 has a cavity 221 for heat insulation, which helps to further improve the heat insulation effect of the barrier 220.

[0086] Specifically, the cavity 221 can be filled with gas, such as air. Of course, the cavity 221 can also be evacuated, which is not limited here.

[0087] In some embodiments, the first heating element 410 and the second heating element 420 are both heating films. Of course, the first heating element 410 and the second heating element 420 can also be heating wires, conductive coatings or other heating structures, which are not limited here.

[0088] It should be noted that in some other embodiments, the heating cavity 110 may also be formed independently on the main body 100 of the device. In this case, there is no need to set the first base 430 and the second base 440 mentioned above, which can simplify the structure of the product and thus help reduce the cost of the product.

[0089] Reference Figure 11In some embodiments, the aerosol substrate segment 210 is an integral solid tobacco. The aerosol substrate segment 210 has a through hole 211 inside for connecting the air inlet channel 120 and the air outlet channel 310, so that the airflow formed when the user inhales can flow through the heated aerosol substrate segment 210, thereby delivering the aerosol formed by the heated aerosol substrate segment 210 into the user's mouth.

[0090] Reference Figure 12 In some other embodiments, the aerosol substrate segment 210 is an integral solid tobacco. The side of the aerosol substrate segment 210 is provided with a through groove 212 for connecting the air inlet channel 120 and the air outlet channel 310, so that the airflow formed when the user inhales can flow through the heated aerosol substrate segment 210, thereby delivering the aerosol formed by the heated aerosol substrate segment 210 into the user's mouth.

[0091] It should be noted that in some other embodiments, the aerosol substrate segment 210 is an integral solid tobacco, and the inner shell 250 is provided with a vent hole corresponding to each receiving cavity 230. The interior of the aerosol substrate segment 210 is provided with an air passage for connecting the air inlet channel 120 and the vent hole. The space inside the inner shell 250 leads to the air outlet channel 310 so that the airflow formed when the user inhales can flow through the heated aerosol substrate segment 210, thereby delivering the aerosol formed by the heated aerosol substrate segment 210 into the user's mouth.

[0092] It should be noted that in some other embodiments, the aerosol substrate segment 210 is an integral solid tobacco, and there is a gap between at least one side of the aerosol substrate segment 210 and the inner wall of the receiving cavity 230, so that the airflow formed when the user inhales can flow through the heated aerosol substrate segment 210. In this case, there is no need to deliberately set the above-mentioned through hole 211, through groove 212 or air passage.

[0093] 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.

[0094] Reference Figure 2 and Figure 16 In some embodiments, the nozzle 300 is provided with a limiting groove 320 extending radially along the aerosol substrate assembly 200 at one end near the aerosol substrate assembly 200, and the barrier 220 is provided with a protrusion 222 inserted into the limiting groove 320 at one end near the nozzle 300, so that the nozzle 300 can drive the aerosol substrate assembly 200 to rotate. Its structure is simple and easy to implement.

[0095] It should be noted that in some other embodiments, the limiting groove 320 may also be provided at the end of the barrier 220 near the nozzle 300, and correspondingly, the protrusion 222 is provided at the end of the nozzle 300 near the aerosol substrate assembly 200.

[0096] It should be noted that in some other embodiments, the suction nozzle 300 and the barrier 220 can be integrally formed or connected by screws.
