Description

Technical Field

[0001] This application relates to the field of atomization technology, and more specifically, to an atomizing core assembly, an atomizing cartridge, and an aerosol generating device. Background Technology

[0002] An aerosol generating device is a small device that uses heating technology to act on an aerosol generating matrix and generate aerosols. In related technologies, an aerosol generating device includes an atomizing cartridge, which includes an atomizing core assembly. The atomizing cartridge stores the aerosol generating matrix, which enters the atomizing core assembly through an inlet. The atomizing core assembly heats and atomizes the aerosol generating matrix, thereby generating an aerosol for the user to inhale.

[0003] However, in related technologies, the liquid inlet is usually higher than the lowest liquid level of the aerosol generating matrix, making it difficult for the aerosol generating matrix below the liquid inlet to enter the atomizing core component. This results in the aerosol generating matrix not being fully atomized, leading to low space utilization of the atomizing cartridge. Utility Model Content

[0004] The embodiments of this application provide an atomizing core assembly, an atomizing bullet, and an aerosol generating device to solve at least one of the aforementioned technical problems.

[0005] The atomizing core assembly of this application is configured to receive and atomize an aerosol generating matrix. The atomizing core assembly includes a seal, an atomizing tube, and an atomizing core. The seal has a mounting cavity and a notch communicating with the mounting cavity. The atomizing tube is housed in the mounting cavity and has a gap between it and the inner wall of the mounting cavity. The atomizing tube has an atomizing chamber and a first liquid inlet communicating with the atomizing chamber. The notch, the gap, and the first liquid inlet are interconnected. The atomizing core is housed in the atomizing chamber and connected to the atomizing tube. After the aerosol generating matrix enters the gap through the notch, it can enter the first liquid inlet through capillary action. The atomizing core is configured to heat the aerosol generating matrix to generate an aerosol.

[0006] In some embodiments, the size of the gap in the radial direction of the atomizing core assembly is greater than or equal to 0.2 mm and less than or equal to 0.8 mm.

[0007] In some embodiments, the seal includes a body portion and an extension portion. The body portion has a groove. The extension portion surrounds the groove and extends away from the groove to form an extension cavity. The extension cavity and the groove together form the mounting cavity, and the projection of the extension portion lies within the projection plane of the body portion in a projection plane perpendicular to the extension direction of the extension portion.

[0008] In some embodiments, in the height direction of the atomizing core assembly, the height of the end of the extension away from the body is greater than or equal to the height of the lowest point of the first liquid inlet, and less than or equal to the height of the highest point of the first liquid inlet.

[0009] In some embodiments, the projection of the extension at least partially covers the projection of the first liquid inlet in a projection plane perpendicular to the height direction of the atomizing core assembly.

[0010] In some embodiments, in the height direction of the atomizing core assembly, one end of the extension from the body is located between the lowest point of the first liquid inlet and the highest point of the first liquid inlet, and the distance between the end of the extension from the body and the lowest point of the first liquid inlet is 50% to 100% of the distance between the lowest point of the first liquid inlet and the highest point of the first liquid inlet.

[0011] In some embodiments, the atomizing core includes a fixing member, a liquid storage member, a heating element, and a mounting base. The fixing member is connected to the atomizing tube and the sealing member, and has a second liquid inlet hole communicating with the atomizing chamber. The liquid storage member is housed within the fixing member and configured to store the aerosol generating matrix. The heating element is housed within the fixing member and configured to heat the aerosol generating matrix to generate the aerosol. The mounting base has leads of the heating element abutting against the mounting base and the fixing member.

[0012] In some embodiments, the seal further includes a first air inlet communicating with the mounting cavity. The atomizing core assembly also includes a mounting base and a first liquid-absorbing element. The mounting base has a mounting groove and a second air inlet communicating with the mounting groove, and one end of the seal away from the atomizing tube is disposed on the mounting base. The first liquid-absorbing element is disposed in the mounting groove and has a third air inlet; the second air inlet, the third air inlet, and the first air inlet communicate with the atomizing cavity to form an air intake channel.

[0013] This application also provides an atomizing bullet. The atomizing bullet includes the atomizing core assembly and the oil storage assembly described in any of the above embodiments. The oil storage assembly is connected to the atomizing core assembly and is configured to store the aerosol generation matrix.

[0014] In some embodiments, the oil storage assembly includes an oil cup. The mounting base of the atomizing core assembly is connected to the oil cup, and the seal and the atomizing tube are housed within the oil cup. The oil cup, the seal, and the atomizing tube together form a liquid storage chamber, which communicates with the first liquid inlet. The liquid storage chamber is configured to store the aerosol generation matrix.

[0015] In some embodiments, the oil cup includes a communicating reservoir and a suction chamber. The reservoir and suction chamber are connected, and the sealing element and the atomizing tube are housed in the reservoir. The oil storage assembly further includes a plugging element and a second suction element. The plugging element is housed in the reservoir and connects the atomizing tube and the oil cup. The plugging element is configured to seal the gap between the inner wall of the oil cup and the outer wall of the atomizing tube. The second suction element is housed in the suction chamber.

[0016] This application also provides an aerosol generating device. The aerosol generating device includes a power supply component and an atomizing bullet as described in any of the above embodiments, wherein the atomizing bullet is detachably connected to the power supply component.

[0017] In the atomizing core assembly, atomizing bullet, and aerosol generating device of this application, when the liquid level of the aerosol generating matrix is ​​higher than the first liquid inlet, the aerosol generating matrix can flow directly into the first liquid inlet by its own gravity; when the liquid level of the aerosol generating matrix is ​​lower than the first liquid inlet, the aerosol generating matrix can flow into the gap between the atomizing tube and the inner wall of the mounting cavity through the notch, and then climb into the first liquid inlet through the capillary action of the gap. In this way, the atomizing core assembly can deliver the aerosol generating matrix to the atomizing core for atomization when the liquid level of the aerosol generating matrix is ​​low, thereby improving the utilization rate of the aerosol generating matrix and the space utilization rate of the atomizing core assembly.

[0034] Please see Figure 1 and Figure 3The atomizing cartridge 100 is used to store an aerosol generating matrix and to heat and atomize the aerosol generating matrix to generate an aerosol for the user to inhale. The atomizing cartridge 100 of this application includes an atomizing core assembly 10 and an oil storage assembly 30. The atomizing core assembly 10 is configured to receive and atomize the aerosol generating matrix stored in the oil storage assembly 30. The oil storage assembly 30 has an oil storage chamber 50, which stores the aerosol generating matrix. The atomizing core assembly 10 is connected to the oil storage assembly 30 and housed within the oil storage chamber 50. Thus, on the one hand, the atomizing core assembly 10 can seal the oil storage chamber 50 to prevent leakage of the aerosol generating matrix; on the other hand, the aerosol generating matrix can enter the atomizing core assembly 10. After entering, the atomizing core assembly 10 uses its own structure (such as a heating wire or other atomizing elements) to heat the aerosol generating matrix, causing it to vaporize and form an aerosol.

[0035] Please see Figure 1 , Figure 2 and Figure 4 The atomizing core assembly 10 of this application includes a sealing member 11, an atomizing tube 13, and an atomizing core 15. The sealing member 11 has a mounting cavity 111 and a notch 117 communicating with the mounting cavity 111. The atomizing tube 13 is housed in the mounting cavity 111 and has a gap 14 between it and the inner wall of the mounting cavity 111. The atomizing tube 13 has an atomizing chamber 131 and a first liquid inlet 133 communicating with the atomizing chamber 131. The notch 117, the gap 14, and the first liquid inlet 133 are connected. The atomizing core 15 is housed in the atomizing chamber 131 and connected to the atomizing tube 13. After the aerosol generating matrix enters the gap 14 through the notch 117, it can enter the first liquid inlet 133 through capillary action. The atomizing core 15 is configured to heat the aerosol generating matrix to generate aerosol.

[0036] Specifically, the seal 11 has a mounting cavity 111 for mounting and accommodating the atomizing tube 13 and the atomizing core 15. The cross-sectional shape of the mounting cavity 111 can be rectangular, circular, or other shapes. The portion of the atomizing tube 13 located below the Z-direction in the height direction is in close contact with the seal 11, while the portion of the atomizing tube 13 located above the Z-direction in the height direction has a gap 14 with the seal 11. Preferably, the shape and size of the mounting cavity 111 match the outer contour of the atomizing tube 13, thereby ensuring a relatively uniform gap 14 between the atomizing tube 13 and the mounting cavity 111, and a uniform fit between the atomizing tube 13 and the mounting cavity 111. The seal 11 can be made of materials such as rubber, silicone, plastic, or synthetic fibers. Among them, rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. There can be one or more seals 11. In one example, the seal 11 is molded separately and then fitted onto the atomizing tube 13; in another example, the seal 11 is fitted onto and molded onto the atomizing tube 13 in the form of rubber coating or the like.

[0037] The notch 117 is used to allow the aerosol generating matrix to flow into the gap 14 between the atomizing tube 13 and the inner wall of the mounting cavity 111. There may be one or more notches 117. Exemplarily, this application has four notches 117 arranged around the seal 11 in the circumferential direction R, thus ensuring that the aerosol generating matrix flows uniformly into the gap 14.

[0038] In this application, the atomizing core assembly 10 has an axis X in the height direction Z, and the axis X is parallel to the height direction Z. The radial direction L of the atomizing core assembly 10 is perpendicular to the axis X and points towards or away from the axis X in any cross-section of the atomizing core assembly 10 perpendicular to the height direction Z. The circumferential direction R of the atomizing core assembly 10 is along the tangent direction of the cross-section circumference in any cross-section of the atomizing core assembly 10 perpendicular to the height direction Z, surrounding the axis X and perpendicular to the radial direction L.

[0039] Capillary action is the phenomenon where a liquid (such as an aerosol-generating matrix) rises or falls against gravity due to the difference between cohesive and adhesive forces. When the liquid level of the aerosol-generating matrix in the oil storage chamber 50 is higher than the first inlet hole 133, the matrix will flow directly into the gap 14 from the notch 117 and further into the first inlet hole 133. When the liquid level of the aerosol-generating matrix is ​​lower than the first inlet hole 133, the aerosol-generating matrix can climb through the gap 14 and enter the first inlet hole 133 through capillary action.

[0040] The atomizing tube 13 is provided with an atomizing chamber 131 and a first liquid inlet 133. The aerosol generating matrix enters the atomizing chamber 131 through the first liquid inlet 133. There can be one or more first liquid inlets 133. Exemplarily, this application has four first liquid inlets 133. The opening shape of the first liquid inlet 133 can be circular, triangular, or polygonal, etc., and is not limited here. The shapes of multiple first liquid inlets 133 can be the same or different. Exemplarily, some of the first liquid inlets 133 in this application are racetrack-shaped. After the aerosol generating matrix enters the first liquid inlet 133, it can be heated by the atomizing core 15 to generate aerosol.

[0041] The atomizing tube 13 may be made of materials including, but not limited to, plastics, aluminum alloys, copper, iron, steel, and carbon fiber composites. In one example, the atomizing tube 13 may be made of plastic, which makes it lighter and facilitates the portability of the aerosol generating device 1000. In another example, the atomizing tube 13 may be made of a high-temperature resistant material, which prevents the atomizing tube 13 from being damaged by heat (e.g., deformation). High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK), high-melting-point metals, and high-temperature ceramics.

[0042] The atomizing core 15 is a structure used to heat the aerosol generating matrix to generate aerosols. The aerosol generating matrix is ​​a processed product capable of generating aerosols under heating, ultrasonication, or mechanical vibration. The aerosol generating matrix can be liquid, fully solid, or semi-solid. The aerosol can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. In some embodiments of this application, the aerosol generating matrix is ​​liquid.

[0043] In some embodiments, the atomizing core 15 can heat the object being heated (such as an aerosol generating matrix) through direct contact. For example, the atomizing core 15 can directly convert other forms of energy, such as electrical energy, chemical energy, or solar energy, into heat energy, which is then conducted to other parts that need to be heated. In other embodiments, the atomizing core 15 can heat the object being heated in a non-contact manner. For example, the atomizing core 15 emits other forms of energy, such as electromagnetic waves, lasers, infrared light, or thermal radiation, that can directly act on the surface of the part to be heated, thereby raising the temperature of the area receiving the electromagnetic waves, lasers, infrared light, or thermal radiation.

[0044] At least a portion of the atomizing core 15 is disposed within the atomizing chamber 131. This reduces the space occupied by the atomizing core 15 and the atomizing tube 13, which is beneficial for miniaturizing the atomizing core assembly 10. Furthermore, the atomizing tube 13 protects the atomizing core 15, thereby reducing the possibility of damage to the atomizing core 15, extending its service life, and preventing users from directly seeing the internal structure of the atomizing core 15, thus improving the appearance of the atomizing core assembly 10.

[0045] In the atomizing core assembly 10 of this application, when the liquid level of the aerosol generating matrix is ​​higher than the first liquid inlet 133, the aerosol generating matrix can flow directly into the first liquid inlet 133 by its own gravity; when the liquid level of the aerosol generating matrix is ​​lower than the first liquid inlet 133, the aerosol generating matrix can flow from the notch 117 into the gap 14 between the atomizing tube 13 and the inner wall of the mounting cavity 111, and then climb into the first liquid inlet 133 through the capillary action of the gap 14. In this way, the atomizing core assembly 10 can deliver the aerosol generating matrix to the atomizing core 15 for atomization when the liquid level of the aerosol generating matrix is ​​low, thereby improving the utilization rate of the aerosol generating matrix and the space utilization rate of the atomizing core assembly 10.

[0046] Please see Figure 3 and Figure 6 In some embodiments, the size of the gap 14 in the radial direction L of the atomizing core assembly 10 is greater than or equal to 0.2 mm and less than or equal to 0.8 mm.

[0047] Specifically, the size of the gap 14 can be 0.2 mm, 0.25 mm, 0.26 mm, 0.32 mm, 0.43 mm, 0.52 mm, 0.58 mm, 0.63 mm, 0.73 mm, or 0.8 mm. If the size of the gap 14 is less than 0.2 mm, the flow of the aerosol generation matrix will be obstructed, making it difficult to flow smoothly into the first liquid inlet 133, thus affecting the atomization effect. If the size of the gap 14 is greater than 0.8 mm, the capillary effect will be significantly reduced, and the aerosol generation matrix cannot effectively climb into the first liquid inlet 133, which is also detrimental to the atomization process.

[0048] The gap 14 has a size greater than or equal to 0.2 mm and less than or equal to 0.8 mm, which ensures that the aerosol generation matrix can flow smoothly from the notch 117 into the gap 14, and also ensures that the aerosol generation matrix can climb into the first liquid inlet hole 133 by capillary action.

[0049] Please see Figure 4 and Figure 5 In some embodiments, the seal 11 includes a body portion 113 and an extension portion 115. The body portion 113 is provided with a groove 1131. The extension portion 115 surrounds the groove 1131 and extends in a direction away from the groove 1131 to form an extension cavity 1151. The extension cavity 1151 and the groove 1131 together form a mounting cavity 111, and in a projection plane perpendicular to the extension direction of the extension portion 115, the projection of the extension portion 115 lies in the projection plane of the body portion 113.

[0050] Specifically, the body portion 113 and the extension portion 115 are disposed opposite each other in the height direction Z, with the extension portion 115 being closer to the first liquid inlet 133 than the body portion 113. At least a portion of the atomizing core 15 is connected to the groove 1131, thereby fixing the atomizing core 15 within the seal 11. The extension portion 115 surrounds the groove 1131 and extends away from the groove 1131 in a direction away from the groove 1131 (i.e., the height direction Z), forming an extension cavity 1151. The extension cavity 1151 increases the dimension of the mounting cavity 111 in the height direction Z, which on the one hand allows it to form a gap 14 with the atomizing tube 13, and on the other hand provides a limit for the atomizing tube 13. The projection of the extension portion 115 lies within the projection plane of the body portion 113, that is, the volume of the extension portion 115 is relatively small, which can reduce the area occupied by the extension portion 115 in the oil storage cavity 50, thereby freeing up more space for the aerosol generation matrix, allowing the oil storage cavity 50 to accommodate more aerosol generation matrix.

[0051] Please see Figure 5 and Figure 6In some embodiments, in the height direction Z of the atomizing core assembly 10, the height H1 of the end of the extension 115 away from the body portion 113 is greater than or equal to the height H2 of the lowest point 1331 of the first liquid inlet, and less than or equal to the height H3 of the highest point 1333 of the first liquid inlet.

[0052] Specifically, if the height H1 of the end of the extension 115 furthest from the main body 113 is less than the lowest point height of the first liquid inlet 133, then even if the aerosol generating matrix rises under capillary action, it will be difficult to enter the first liquid inlet 133, resulting in poor atomization. If the height H1 of the end of the extension 115 furthest from the main body 113 is greater than the highest point height of the first liquid inlet 133, the aerosol generating matrix is ​​prone to accumulate in the extension 115 and cannot enter the first liquid inlet 133, resulting in waste of the aerosol generating matrix. When the height H1 of the end of the extension 115 furthest from the main body 113 is greater than or equal to the height H2 of the lowest point 1331 of the first liquid inlet and less than or equal to the height H3 of the highest point 1333 of the first liquid inlet, it can ensure that the aerosol generating matrix enters the first liquid inlet 133 under capillary action, thereby being atomized by the atomizing core 15, and avoids the accumulation of the aerosol generating matrix in the extension 115.

[0053] Please see Figure 3 and Figure 4 In some embodiments, the projection of the extension 115 at least partially covers the projection of the first liquid inlet 133 in the projection plane perpendicular to the height direction Z of the atomizing core assembly 10.

[0054] Specifically, in the projection plane perpendicular to the height direction Z of the atomizing core assembly 10, the projection of the extension 115 at least partially covers the projection of the first liquid inlet 133. This ensures that the aerosol generating matrix can enter the first liquid inlet 133 under capillary action and thus be atomized by the atomizing core 15. If the extension 115 is too high, the aerosol generating matrix is ​​prone to accumulate in the extension 115 and cannot enter the first liquid inlet 133. This accumulation of the aerosol generating matrix in the extension 115 prevents it from smoothly entering the first liquid inlet 133, thereby affecting the atomization efficiency and potentially wasting the matrix.

[0055] The projection of the extension 115 at least partially covers the projection of the first liquid inlet 133, which can ensure that the aerosol generation matrix rises to the position of the first liquid inlet 133 through capillary action, and also prevent the aerosol generation matrix from accumulating in the extension 115.

[0056] Please see Figure 5 and Figure 6In some embodiments, in the height direction Z of the atomizing core assembly 10, one end of the extension 115 away from the body portion 113 is located between the lowest point 1331 and the highest point 1333 of the first liquid inlet, and the distance D1 between the end of the extension 115 away from the body portion 113 and the lowest point 1331 of the first liquid inlet is 50% to 100% of the distance D2 between the lowest point 1331 and the highest point 1333 of the first liquid inlet.

[0057] Specifically, the distance D1 between the end of the extension 115 away from the main body 113 and the lowest point 1331 of the first liquid inlet is 50%, 56%, 62%, 68%, 72%, 77%, 83%, 87%, 95%, or 100% of the distance D2 between the lowest point 1331 and the highest point 1333 of the first liquid inlet. If the distance D1 between the end of the extension 115 away from the main body 113 and the lowest point 1331 of the first liquid inlet is greater than 100% of the distance D2 between the lowest point 1331 and the highest point 1333 of the first liquid inlet, that is, if the end of the extension 115 away from the main body 113 exceeds the highest point 1333 of the first liquid inlet, the aerosol generating matrix between the end of the extension 115 away from the main body 113 and the highest point 1333 of the first liquid inlet is easily accumulated and difficult to enter the first liquid inlet 133, resulting in waste of the aerosol generating matrix. If the distance D1 between the end of the extension 115 furthest from the main body 113 and the lowest point 1331 of the first liquid inlet is less than 50% of the distance D2 between the lowest point 1331 and the highest point 1333 of the first liquid inlet, then the end of the extension 115 furthest from the main body 113 is too close to the lowest point 1331 of the first liquid inlet, and is located at a lower position of the first liquid inlet 133. In this case, even with capillary action, the aerosol generating matrix will have difficulty climbing to the first liquid inlet 133, resulting in poor atomization effect.

[0058] When the distance D1 between the end of the extension 115 away from the main body 113 and the lowest point 1331 of the first liquid inlet is between 50% and 100% of the distance D2 between the lowest point 1331 and the highest point 1333 of the first liquid inlet, it can ensure that the end of the extension 115 away from the main body 113 is within a reasonable height range of the first liquid inlet 133. This ensures that the aerosol generating matrix can climb to the first liquid inlet 133 through capillary action, and also ensures that the aerosol generating matrix does not accumulate in the gap 14 and is difficult to enter the liquid inlet.

[0059] Please see Figure 4 and Figure 5In some embodiments, the atomizing core 15 includes a fixing member 151, a heating element 153, a liquid storage member 155, and a fixing base 157. The fixing member 151 is connected to the atomizing tube 13 and the sealing member 11, and is provided with a second liquid inlet 159, which communicates with the atomizing chamber 131. The liquid storage member 155 is housed within the fixing member 151 and is configured to store the aerosol generating matrix. The heating element 153 is housed within the fixing member 151 and is configured to heat the aerosol generating matrix to generate aerosol. The leads 1531 of the heating element abut against the fixing base 157 and the fixing member 151.

[0060] Specifically, the fixing member 151 is used to connect with the atomizing tube 13 and the sealing member 11 to fix the atomizing core 15. A portion of the fixing member 151 is inserted into the groove 1131 and forms a tight fit with the groove 1131, thereby ensuring that the fixing member 151 is fixed to the sealing member 11, preventing displacement or loosening of the atomizing core 15 during use, and ensuring the stability of the atomization process. The atomizing tube 13 is sleeved on the fixing member 151, and the fixing method includes, but is not limited to, interference fit and bonding. The fixing member 151 is also used to install and fix the heating element 153 and the liquid storage element 155. The heating element 153 and the liquid storage element 155 are housed within the fixing member 151. A second liquid inlet 159 is provided on the fixing member 151 and communicates with the atomizing chamber 131. The aerosol generating matrix entering the atomizing chamber 131 from the first liquid inlet 133 flows into the fixing member 151 through the second liquid inlet 159 and is then adsorbed by the liquid storage element 155. The reservoir 155 can store and conduct aerosol generation matrix. The heat generated by the heating element 153 can be rapidly transferred to the aerosol generation matrix in the reservoir 155, heating it and converting it into aerosol.

[0061] The liquid storage component 155 is used to store the aerosol generating matrix. The heating element 153 is connected to the liquid storage component 155 and is used to heat the aerosol generating matrix to generate aerosols. The liquid storage component 155 can be a liquid storage cotton; the material of the liquid storage component 155 includes, but is not limited to, polypropylene, polyethylene, polyester fiber, and glass fiber.

[0062] The heating element 153 is a component in the atomizing core 15 capable of heating the aerosol-generating matrix in the liquid reservoir 155. Specifically, the atomizing core 15 also includes a conductive element electrically connected to the heating element 153 and used to transfer electrical energy to the heating element 153. For example, the cross-sectional shape of the liquid reservoir 155 may be annular, and the heating element 153 may include heating lines (such as PVD film or printed thick film, etc.). The heating element 153 is disposed on the inner wall of the liquid reservoir 155. When the conductive element transfers electrical energy to the heating element 153, the heating element 153 can generate heat to heat the aerosol-generating matrix in the liquid reservoir 155.

[0063] It should be noted that in some embodiments, in addition to the heating circuit, the heating element 153 may also include a heating film, a heating sheet, a heating wire, and a heating mesh, etc., and this application does not impose any limitations. The material of the heating element 153 can be a metallic material with appropriate impedance, such as at least one of silver, silver-palladium, platinum, gold, copper, nickel, aluminum, and tungsten; the material of the heating element 153 can also be a metal composite material, such as at least one of cermet, metallic glass, and conductive ceramic. It should be noted that in some embodiments, the heating element 153 may have certain antioxidant properties.

[0064] The mounting base 157 is used to fix the pins 1531 of the heating element. It is understood that the heating element 153 needs to generate heat when energized; therefore, the heating element 153 extends out of the mounting base 151 through its pins 1531 to receive electrical energy. The mounting base 157 is housed within the mounting base 151 and has multiple recesses. The shape of the recesses matches the pins 1531 of the heating element. The pins 1531 of the heating element can be accommodated by the recesses and abutted by the inner wall of the mounting base 151 and the outer wall of the mounting base 157 (i.e., the inner wall of the recesses), ensuring a secure connection of the pins 1531 of the heating element and preventing poor electrical contact or circuit interruption due to loosening of the pins 1531.

[0065] Please see Figure 4 and Figure 5 In some embodiments, the seal 11 is further provided with a first air inlet 119 communicating with the mounting cavity 111. The atomizing core assembly 10 also includes a mounting base 17 and a first liquid suction member 19. The mounting base 17 is provided with a mounting groove 173 and a second air inlet 171 communicating with the mounting groove 173. One end of the seal 11 away from the atomizing tube 13 is disposed on the mounting base 17. The first liquid suction member 19 is disposed in the mounting groove 173 and has a third air inlet 191. The second air inlet 171, the third air inlet 191 and the first air inlet 119 communicate with the atomizing cavity 131 to form an air intake channel.

[0066] Specifically, the mounting base 17 is used to mount the sealing element 11. The end of the sealing element 11 furthest from the atomizing tube 13 is mounted on the mounting base 17, thereby ensuring the stable fixation of the sealing element 11 and preventing displacement or shaking during use, thus ensuring the stability of the entire atomizing core assembly 10 structure. Simultaneously, the mounting base 17 provides a mounting platform for other components (such as the oil cup 31 hereinafter). The first air inlet 119, the second air inlet 171, and the third air inlet 191 can be one or more, and are not limited in this application. Exemplarily, in this application, the first air inlet 119, the second air inlet 171, and the third air inlet 191 are all one, located at the center of the sealing element 11, the mounting base 17, and the first liquid suction element 19. The second air inlet 171, the third air inlet 191, and the first air inlet 119 are interconnected and form an air intake channel with the atomizing chamber 131, ensuring airflow during atomization. The mounting groove 173 is used to accommodate the first liquid suction member 19 to fix the first liquid suction member 19.

[0067] When a user inhales, air enters from the outside, passing sequentially through the second air inlet 171, the third air inlet 191, and the first air inlet 119 before entering the atomization chamber 131. The airflow causes the aerosol generating matrix in the liquid storage component 155 to be heated and atomized by the heating element 153. The resulting aerosol is carried by the airflow through the atomization chamber 131 and ultimately inhaled by the user. The inflow of air not only facilitates the atomization of the aerosol generating matrix but also carries the atomized aerosol out of the atomization chamber 131, allowing it to be smoothly inhaled by the user.

[0068] Please see Figure 3 and Figure 4 In some embodiments, the oil storage assembly 30 includes an oil cup 31. The mounting base 17 of the atomizing core assembly 10 is connected to the oil cup 31, and the sealing element 11 and the atomizing tube 13 are housed in the oil cup 31. The oil cup 31, the sealing element 11, and the atomizing tube 13 together form a liquid storage chamber 50, which communicates with the first liquid inlet 133. The liquid storage chamber 50 is configured to store the aerosol generation matrix.

[0069] Specifically, the oil cup 31 is used to contain the aerosol generation matrix. Further, the oil cup 31 is connected to the mounting base 17, and other components of the atomizing core assembly 10 are housed within the oil cup 31. The oil cup 31, the sealing element 11, and the atomizing tube 13 together form a liquid storage chamber 50, which is used to store the aerosol generation matrix. The liquid storage chamber 50 communicates with the first liquid inlet 133, allowing the aerosol generation matrix to flow from the liquid storage chamber 50 into the first liquid inlet 133 for atomization. In addition, the oil cup 31 is provided with an oil filling hole for injecting the aerosol generation matrix into the liquid storage chamber 50. After filling, the oil sealing element 36 seals the oil filling hole to prevent leakage of the aerosol generation matrix and maintain the airtightness of the atomizing cartridge 100.

[0070] Please see Figures 3 to 5 In some embodiments, the oil cup 31 includes a connected liquid storage chamber 50 and a suction chamber 39. The sealing member 11 and the atomizing tube 13 are housed in the liquid storage chamber 50. The oil storage assembly 30 also includes a blocking member 33 and a second suction member 35. The blocking member 33 is housed in the liquid storage chamber 50 and connects the atomizing tube 13 and the oil cup 31. The blocking member 33 is configured to block the gap between the inner wall of the oil cup 31 and the outer wall of the atomizing tube 13. The second suction member 35 is housed in the suction chamber 39.

[0071] Specifically, the suction chamber 39 is used to install the second liquid suction element 35. The second liquid suction element 35 is used to absorb the liquid formed by the condensation of aerosol in the suction chamber 39 (hereinafter referred to as condensate), preventing the condensate from being sucked into the user's mouth, thereby improving the user's suction experience.

[0072] The sealing element 33 is used to seal the gap 14 between the atomizing tube 13 and the oil cup 31. It should be noted that in some embodiments, the sealing element 33 may be made of materials such as rubber, silicone, plastic, or synthetic fibers. Rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. There may be one or more sealing elements 33, and this application is not limited to any one of them. In one example, the sealing element 33 is molded separately and then fitted onto the atomizing tube 13; in another example, the sealing element 33 is fitted onto and molded onto the atomizing tube 13 in a form such as overmolding. The sealing element 33 can seal the gap 14 between the atomizing tube 13 and the oil cup 31, ensuring that the aerosol generation matrix in the liquid storage chamber 50 will not be inhaled by the user after flowing out to the suction chamber 39, thus reducing the risk of leakage.

[0073] Please see Figure 1 and Figure 3 The present application also provides an aerosol generating device 1000. The aerosol generating device 1000 includes a power supply component 300 and an atomizing bullet 100 according to any of the above embodiments, wherein the atomizing core component 10 is detachably connected to the power supply component 300.

[0074] Specifically, the aerosol generating device 1000 of this application includes a power supply component 300 and an atomizing core component 10 of any of the above embodiments, wherein the atomizing core component 10 and the power supply component 300 are detachably connected. This facilitates the assembly and disassembly of the power supply component 300 and the atomizing core component 10, improving the user experience.

[0075] The power supply component 300 and the atomizing tube 13 of the atomizing core component 10 can be detachably connected to each other. The detachable connection methods include, but are not limited to, magnetic connection, snap-fit ​​connection, and bolt connection. For example, when the power supply component 300 and the atomizing tube 13 are magnetically connected, a first magnetic element can be provided on the outer shell, and a second magnetic element can be provided on the atomizing tube 13. The first and second magnetic elements cooperate to achieve a magnetic connection between the outer shell and the atomizing tube 13.
