Description

Technical Field

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

[0002] An aerosol generating device is a device that uses heating technology to act on an aerosol generating matrix and generate aerosols. In related technologies, an aerosol generating device includes an atomizer with an atomization channel. The atomizer heats the aerosol generating matrix to generate aerosols within the atomization channel. The heating surface of the atomizer is opposite to the atomization channel and perpendicular to its central axis. However, this configuration results in the aerosol generated at the heating surface needing to flow upwards around the atomizer before exiting the atomization channel when the device is aspirated. This leads to a complex aerosol flow path and lower aerosol aspiration smoothness. Utility Model Content

[0036] An aerosol generating device is a apparatus that uses heating technology to act on an aerosol generating matrix and generate aerosols. In related technologies, an aerosol generating device includes an atomizer with an atomization channel. The atomizer heats the aerosol generating matrix to generate aerosols within the atomization channel. The heating surface of the atomizer is opposite to the atomization channel and perpendicular to its central axis. However, this configuration results in the aerosol generated at the heating surface needing to flow upwards around the atomizer before exiting the atomization channel when the aerosol generating device is drawn in. This leads to a complex aerosol flow path and low suction smoothness. To solve the above problems, please refer to [link to relevant documentation]. Figure 1 This application provides an atomizer 100 and an aerosol generating device 1000.

[0037] Please see Figure 1 The aerosol generating device 1000 of this application includes an atomizer 100 and an electronic control component 300, with the atomizer 100 and the electronic control component 300 being electrically connected.

[0038] It is understood that the atomizer 100 is a structure in the aerosol generating apparatus 1000 capable of heating 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 in a liquid state, or in a fully solid or semi-solid state. 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 can be in a liquid state.

[0039] The electronic control component 300 is a structure in the aerosol generating device 1000 used to control the operation of the atomizer 100. In some embodiments of this application, the electronic control component 300 includes a power supply and a controller. The power supply provides electrical energy to the atomizer 100. The controller is electrically connected to the power supply and is used at least to regulate the voltage of the electrical energy. Exemplarily, when the aerosol generating device 1000 is being aspirated, the controller can control the power supply to output electrical energy to the atomizer 100 and regulate the voltage of the output electrical energy so that the adjusted voltage is suitable for the atomizer 100. In this case, the atomizer 100 can heat and atomize the aerosol generating matrix to generate aerosol for the user to inhale. When the aerosol generating device 1000 is not being aspirated, the controller can control the power supply to stop providing electrical energy to the atomizer 100. In this case, the atomizer 100 will not heat the aerosol generating matrix. It should be noted that, in some embodiments, the power source can be a dry cell battery or a rechargeable battery, including but not limited to lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries.

[0040] Furthermore, in some embodiments, the aerosol generating device 1000 further includes a housing 500 for housing the atomizer 100 and the electronic control assembly 300. Specifically, the housing 500 is a structure in the aerosol generating device 1000 that can accommodate and protect the atomizer 100 and other devices. The material of the housing 500 includes, but is not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. In some embodiments, the housing 500 may be made of plastic, which makes the housing 500 lighter and facilitates the portability of the aerosol generating device 1000. In other embodiments, the housing 500 may be made of a high-temperature resistant material, which prevents the housing 500 from being damaged by heat (e.g., deformation) and ensures the stability and reliability of the aerosol generating device 1000. High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK), high-melting-point metals, and high-temperature ceramics.

[0041] Since the aerosol generating device 1000 in this embodiment includes an atomizer 100, it is understood that the aerosol generating device 1000 has at least the same beneficial effects as the atomizer 100. Therefore, for the beneficial effects of the aerosol generating device 1000, please refer to the beneficial effects of the atomizer 100 described below.

[0042] Please see Figures 1 to 3 The atomizer 100 of this application includes an atomizing base 10, a liquid storage component 30, and an atomizing core 50. The atomizing base 10 is provided with an atomizing channel 101. The atomizing base 10 includes a first side 102 and a second side 103 facing away from each other. The central axis X of the atomizing channel 101 is parallel to the direction from the first side 102 to the second side 103 of the atomizing base 10. The liquid storage component 30 is connected to the atomizing base 10. The liquid storage component 30 is provided with a liquid storage chamber 31 and a suction channel 33. The liquid storage chamber 31 is located on the first side 102 and is configured to store the aerosol generation matrix. The suction channel 33 communicates with the atomizing channel 101, and the central axis Y of the suction channel coincides with the central axis X of the atomizing channel. The atomizing core 50 is disposed on the atomizing base 10. The atomizing core 50 includes a contact surface 503 and a heating surface 501 facing away from each other. The contact surface 503 is configured to receive the aerosol generating matrix from the liquid storage chamber 31. The heating surface 501 is parallel to the central axis X of the atomizing channel 101. The atomizing core 50 is configured to heat the aerosol generating matrix to generate aerosol at the heating surface 501. The suction channel 33 is configured to allow the aerosol to flow out of the atomizer 100. The heating surface 501 is also parallel to the central axis Y of the suction channel.

[0043] It is understood that the atomizer base 10 is a structure in the atomizer 100 used to house components other than the atomizer base 10. Components other than the atomizer base 10 in this application include, but are not limited to, the atomizer coil 50. The outer contour shape of the atomizer base 10 may include, but is not limited to, cylinders, cubes, cuboids, triangular prisms, and hexagonal prisms. The materials of the atomizer base 10 include, but are not limited to, plastic, glass, ceramic, and metal.

[0044] The liquid reservoir 30 is a structure in the atomizer 100 used to store the aerosol generation matrix. The liquid reservoir 30 is made of materials including, but not limited to, polyester (PET), polypropylene (PP), ABS plastic, aluminum alloy, or glass. The liquid reservoir 31 can be a regular shape such as a cylinder or cone, or an irregular shape. The liquid reservoir 31 is located on the first side 102, so that when the aerosol generating device 1000 is aspirated, the aerosol generation matrix in the liquid reservoir 31 can flow from the first side 102 of the atomizing base 10 into the atomizing base 10 under the combined action of pressure and gravity.

[0045] In some embodiments of this application, the liquid storage device 30 is further provided with a suction channel 33, which is connected to the atomization channel 101 and is configured to allow the aerosol in the atomization channel 101 to flow out of the atomizer 100. The central axis Y of the suction channel coincides with the central axis X of the atomization channel, and the heating surface 501 is parallel to the central axis Y of the suction channel 33.

[0046] In this way, users can draw in the generated aerosol through the suction channel 33, and the suction channel 33 and the atomization channel 101 can form a straight airflow path. In other words, the flow path of the aerosol is straight and there is no structural interference in the flow path. This ensures smooth suction and improves the user's suction taste, while also reducing suction resistance and improving the user's suction experience.

[0047] In some embodiments, the liquid reservoir 30 and the atomizing base 10 can be connected together using either a detachable or non-detachable connection method. Detachable connections include, but are not limited to, snap-fit ​​connections and threaded connections; non-detachable connections include, but are not limited to, bonding and welding.

[0048] The atomizing core 50 is a structure in the atomizer 100 that heats the aerosol-generating matrix to generate aerosol. In some embodiments of this application, the heating surface 501 is tangent to the atomization channel 101, that is, the atomizing core 50 does not extend into the atomization channel 101, thereby preventing the atomizing core 50 from obstructing the flow of aerosol, ensuring smooth inhalation, and improving the user's inhalation experience. In other embodiments of this application, at least a portion of the atomizing core 50 extends into the atomization channel 101, and the heating surface 501 is parallel to the central axis X of the atomization channel, which also prevents the atomizing core 50 from obstructing the flow of aerosol and ensures smooth inhalation. It should be noted that in this embodiment, the portion of the atomizing core 50 extending into the atomization channel 101 does not cross the central axis X of the atomization channel, that is, the atomizing core 50 does not intersect with the central axis X of the atomization channel, and the heating surface 501 is spaced apart from or tangent to the central axis X of the atomization channel.

[0049] In some embodiments, the atomizing core 50 can heat the object being heated (such as an aerosol generating matrix) through direct contact. For example, the atomizing core 50 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 50 can heat the object being heated in a non-contact manner. For example, the atomizing core 50 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.

[0050] Please seeFigure 2 and Figure 3 In some embodiments of this application, the atomizing core 50 includes a heating element 51, which is configured to heat the aerosol generating matrix to generate an aerosol. Specifically, please refer to... Figure 6 The heating element 51 can be the outermost component of the atomizing core 50, and the heating element 51 can form the heating surface 501 of the atomizing core 50. The heating element 51 includes a heating part 511 and two conductive parts 513 electrically connected to the heating part 511. The conductive parts 513 are configured to transmit electrical energy to the heating part 511 so that the heating part 511 is energized and heated.

[0051] It should be noted that the heating element 51 includes, but is not limited to, heating circuits, heating films, heating sheets, heating wires, and heating meshes. The heating element 51 may be made of at least one of the following materials: metallic materials (e.g., nickel, cobalt, zirconium, titanium), metal alloys (e.g., nickel alloys, cobalt alloys, zirconium alloys, titanium alloys, nickel-chromium alloys), graphite, carbon, conductive ceramics, tin-antimony oxide, other ceramic materials, and composite materials of metallic materials.

[0052] For example, the heating element 51 can be an integral structure, that is, the heating part 511 and the two conductive parts 513 can be integrally molded into a single structure. This reduces the number of parts and facilitates the assembly of the heating element 51; on the other hand, it makes the overall resistance of the heating element 51 more stable and the resistance distribution more uniform, thereby contributing to the uniformity of the atomization effect. In one example, the material of both conductive parts 513 can be nickel; the material of the heating part 511 can be stainless steel or nickel-chromium alloy.

[0053] Furthermore, please combine Figure 4 and Figure 5 The atomizer 100 also includes two electrical connectors 70, which pass through the atomizing base 10 and are electrically connected to two conductive parts 513 respectively.

[0054] The electrical connector 70 is a structure in the atomizer 100 used to connect the power supply and the heating element 51. The electrical connector 70 includes, but is not limited to, wire harnesses, leads, and copper busbars. The electrical connector 70 can be made of at least one of the conductive materials selected from copper, aluminum, nickel-iron alloy, gold, and copper alloy. The cross-sectional shape of the electrical connector 70 includes, but is not limited to, circles, squares, and triangles. When the cross-sectional shape of the electrical connector 70 includes a square shape, the contact area between the electrical connector 70 and the heating element 51 is larger, thus improving the stability of the electrical connection.

[0055] Specifically, the arrangement of the two electrical connectors 70 enables the heating element 51 and the power source to form a complete circuit. That is, the electrical energy of the power source can be transmitted to a conductive part 513 of the heating element 51 through one electrical connector 70, so that the heating part 511 of the heating element 51 is energized and heated, and then transmitted back to the power source through the other conductive part 513 of the heating element 51 and the other electrical connector 70, thereby ensuring the normal operation of the atomizing core 50.

[0056] Please combine Figure 7 In some embodiments, the electrical connector 70 includes a connecting portion 71, which is a columnar structure. The connecting portion 71 is fixed to the atomizing base 10 and has a contact end. The contact end is configured to contact the conductive portion 513 so that the connecting portion 71 and the conductive portion 513 are electrically connected.

[0057] Specifically, a columnar structure refers to a structure with a large aspect ratio (length to diameter), that is, the connecting part 71 is a structure with a large aspect ratio (length to diameter). The cross-section of the connecting part 71 can be circular, square, hexagonal, or other regular or irregular shapes. The contact end is the part on the connecting part 71 that can contact the conductive part 513 of the heating element and form an electrical connection. The connecting part 71 can also be electrically connected to the power supply of the electronic control assembly 300. When the electrical connector 70 is installed on the atomizing base 10, the connecting part 71 can form a contact electrical connection with the conductive part 513 through the contact end, thereby allowing electrical energy from the power supply to flow through the connecting part 71 to the conductive part 513, which in turn energizes the heating element 511 to generate heat and heat the aerosol to form the matrix.

[0058] Please combine Figure 8 In some embodiments, the electrical connector 70 further includes a mounting portion 73 connected to the connecting portion 71. The mounting portion 73 is disposed on the atomizing base 10, and a portion of the mounting portion 73 is exposed outside the atomizing base 10 through a second side 103 of the atomizing base 10. The mounting portion 73 is configured to be electrically connected to the power supply of the electronic control assembly 300.

[0059] Specifically, the cross-sectional dimension of the mounting portion 73 is larger than that of the conductive portion 513. As a result, on the one hand, compared to the electrical connector 70 which only includes a connector, the electrical connection between the electrical connector 70 and the power supply is more stable; on the other hand, the mounting portion 73 can serve as a base for mounting the electrical connector 70 on the atomizing base 10, thereby improving the stability of the electrical connector 70 on the atomizing base 10.

[0060] It should be noted that in some embodiments, the mounting portion 73 and the connecting portion 71 are an integral structure, that is, the mounting portion 73 and the connecting portion 71 are a single structure manufactured using an integral molding process, which can improve the structural stability of the electrical connector 70. For example, the electrical connector 70 can be a conductive nail. Of course, in other embodiments, the mounting portion 73 and the connecting portion 71 are separate structures, and the mounting portion 73 and the connecting portion 71 can be combined using a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​connections and threaded connections; non-detachable connection methods include, but are not limited to, bonding and welding.

[0061] In the atomizer 100 of this application embodiment, the atomizing core 50 includes a heating surface 501, which is parallel to the central axis X of the atomizing channel 101. In this way, the aerosol generated in the atomizing channel 101 does not need to bypass the atomizer 101 before it can be inhaled by the user, making the flow path of the aerosol simpler, thereby ensuring smooth inhalation and improving the user's inhalation experience.

[0062] In addition, the aerosol generated in the atomization channel 101 does not need to bypass the atomizer 100 before it can be inhaled by the user. This also reduces aerosol loss caused by collisions between the aerosol and the atomizer 100, and prevents the temperature of the aerosol from dropping, thereby improving the user's inhalation experience.

[0063] The atomizer 100 will be further explained below with reference to the accompanying drawings.

[0064] Please see Figure 2 , Figure 5 and Figure 6 In some embodiments, the atomizing base 10 is provided with a limiting part 11, which is configured to cooperate with the electrical connector 70 so that the electrical connector 70 and the conductive part 513 are kept electrically connected.

[0065] This improves the stability of the electrical connection between the electrical connector 70 and the conductive part 513, preventing the electrical connector 70 from separating from the conductive part 513 due to installation errors or collisions with the atomizer 100. This enhances the stability and reliability of the atomizer 100's operation and ensures a better user experience.

[0066] Specifically, in some embodiments, the limiting part 11 can be a support protrusion, a latch, a claw, an elastic element, etc. For example, the limiting part 11 can be a support protrusion that can abut against the electrical connector 70 to support and limit the electrical connector 70, thereby correcting the tilt angle of the electrical connector 70, preventing the electrical connector 70 from separating from the conductive part 513, and thus improving the stability of the electrical connection between the electrical connector 70 and the conductive part 513.

[0067] It should be noted that the quantitative relationship between the support protrusion and the electrical connector 70 can be one-to-one; or one-to-many, that is, one support protrusion corresponds to one electrical connector 70; or one support protrusion corresponds to two electrical connectors 70.

[0068] Further, please refer to Figures 4 to 6 In some embodiments, the atomizing base 10 includes a first sub-part 13 and a second sub-part 15, which are connected to form an atomizing channel 101. The atomizing core 50 is disposed on the first sub-part 13, and the limiting part 11 extends from the second sub-part 15 toward the first sub-part 13.

[0069] Specifically, please combine Figure 2 In some embodiments, the second sub-part 15 includes a loading seat 151 and an extension 153. The extension 153 protrudes from the loading seat 151 in a direction away from the loading seat 151 along the direction from the second side 103 to the first side 102. The first sub-part 13 is disposed on the loading seat 151 and cooperates with the extension 153 so that the first sub-part 13, the loading seat 151, and the extension 153 together form the atomizing channel 101. The limiting part 11 protrudes from the side of the extension 153 toward the first sub-part 13 toward the first sub-part 13, and the free end of the limiting part 11 abuts against the electrical connector 70 (the connecting part 71 of the electrical connector 70). Thus, the limiting part 11 can support and limit the electrical connector 70, prevent the electrical connector 70 from separating from the conductive part 513, and improve the stability of the electrical connection between the electrical connector 70 and the conductive part 513.

[0070] More specifically, in some embodiments, the extension 153 is provided with a first sealing element 81, which is configured to seal the gap on the extension 153. A second sealing element 83 is provided between the first sub-part 13 and the second sub-part 15, which is configured to seal the gap between the first sub-part 13 and the second sub-part 15. In this way, the first sub-part 13, the extension 153, the loading seat 151, the first sealing element 81, and the second sealing element 83 can together form a relatively closed atomization channel 101, thereby reducing the possibility of aerosol leakage, ensuring the amount of aerosol that can be inhaled, and improving the user's inhalation experience. The second sealing element 83 is disposed between the first sub-part 13 and the loading seat 151, that is, the second sealing element 83 can seal the gap between the first sub-part 13 and the loading seat 151.

[0071] It should be noted that, in some embodiments, the first sealing element 81 and the second sealing element 83 can both be made of at least one of the following materials: rubber, silicone, plastic and synthetic fiber. Among them, the rubber material includes, but is not limited to, natural rubber, fluororubber, polyurethane rubber, EPDM rubber or silicone rubber.

[0072] In some embodiments, the first sub-part 13 and the second sub-part 15 can be joined together by a non-detachable connection, which can improve the connection strength between the first sub-part 13 and the second sub-part 15, reduce the possibility of separation between the first sub-part 13 and the second sub-part 15, and ensure the normal operation of the atomizer 100. The non-detachable connection method includes, but is not limited to, bonding or welding.

[0073] In other embodiments, the first sub-part 13 and the second sub-part 15 can be detachably connected together, which facilitates the installation and removal of the first sub-part 13 and the second sub-part 15, thereby facilitating the maintenance or replacement of the internal components of the atomizing base 10. The detachable connection method includes, but is not limited to, snap-fit ​​connections or bolt connections.

[0074] For example, please refer to Figure 6 The first sub-part 13 may be provided with a male buckle 131, and the second sub-part 15 may be provided with a female buckle 155 that mates with the male buckle 131. The male buckle 131 and the female buckle 155 mate to connect the first sub-part 13 and the second sub-part 15, while ensuring tight contact between the electrical connector 70 and the heating element 51. In addition, the first sub-part 13 may also be provided with a positioning post 133, and the second sub-part 15 may be provided with a positioning hole 157 corresponding to the positioning post 133. The positioning post 133 and the positioning hole 157 mate to limit the positioning of the first sub-part 13 and the second sub-part 15, thereby improving the assembly efficiency of the first sub-part 13 and the second sub-part 15.

[0075] Please see Figure 2 and Figure 5 In some embodiments, the atomizing base 10 is further provided with an air inlet 104, which is connected to the atomizing channel 101 and is configured to allow outside air to flow into the atomizing channel 101.

[0076] Specifically, in some embodiments, the air inlet 104 can be disposed on the loading seat 151 and communicate with the atomization channel 101. When the aerosol generating device 1000 is drawn in, outside air can flow into the atomization channel 101 through the air inlet 104 so that the aerosol generating matrix can generate aerosol when heated.

[0077] More specifically, please combine Figure 1In some embodiments, the second sealing element 83 is provided with a through hole 831, through which the air inlet 104 communicates with the atomization channel 101. Thus, the second sealing element 83 also prevents the aerosol generating matrix (aerosol generating matrix leaking into the atomization channel 101; or condensate formed by aerosol condensation) from contacting the air inlet 104. This reduces the possibility of the air inlet 104 being blocked by the aerosol generating matrix, ensuring the normal operation of the aerosol generating device 1000. Furthermore, it prevents the aerosol generating matrix from leaking out of the atomization base 10 through the air inlet 104, which could damage other structures of the aerosol generating device 1000 (e.g., the electronic control component 300), thereby improving the stability and reliability of the aerosol generating device 1000.

[0078] If the aerosol generating matrix (including the aerosol generating matrix leaking into the atomization channel 101, and the liquid substances formed after aerosol condensation, etc.) leaks outside the atomization base 10 through the air inlet 104, the aerosol generating matrix may damage other structures of the aerosol generating device 1000 (such as the electronic control component 300), affecting the normal operation of the aerosol generating device 1000. Therefore, please refer to... Figure 2 and Figure 5 In some embodiments of this application, the air inlet 104 includes a plurality of spaced micropores 1041, which are configured to prevent the aerosol generating matrix from flowing out of the atomizing base 10. Specifically, when the aerosol generating matrix comes into contact with the air inlet 104, the aerosol generating matrix can form a thin film structure under the action of the surface tension of the plurality of micropores 1041 and cover the air inlet 104 (micropores 1041), thereby preventing the aerosol generating matrix from flowing out of the atomizing base 10 and causing damage to other structures of the aerosol generating device 1000, thus ensuring the normal operation of the aerosol generating device 1000.

[0079] In addition, the air inlet 104 includes multiple spaced micropores 1041, that is, the air inlet 104 adopts a dotted design, which can reduce noise during suction, make the suction smoother, and improve the user's suction experience.

[0080] Understandably, when the aerosol generating device 1000 is being evacuated, the impact force generated by the outside air can break through the thin film structure formed by the aerosol generating matrix, thereby ensuring the normal operation of the aerosol generating device 1000.

[0081] Please see Figure 2 , Figure 4 and Figure 5In some embodiments, the atomizing base 10 is further provided with a liquid inlet channel 105, which includes a first end 1051 and a second end 1053 opposite to each other. The first end 1051 of the liquid inlet channel 105 communicates with the liquid storage chamber, and the second end 1053 of the liquid inlet channel 105 communicates with the atomizing channel 101. A sealing element 85 is provided between the atomizing core 50 and the second end 1053 of the liquid inlet channel 105. The sealing element 85 is configured to seal the gap between the atomizing core 50 and the second end 1053 of the liquid inlet channel 105.

[0082] Specifically, in some embodiments, the aerosol generating matrix in the liquid storage chamber 31 can flow into the liquid inlet channel 105 from the first end 1051 of the liquid inlet channel 105, and flow to the atomizing core 50 through the second end 1053 of the liquid inlet channel 105, so as to be heated and atomized by the atomizing core 50 to generate aerosol. The sealing element 85 is disposed between the atomizing core 50 and the second end 1053 of the liquid inlet channel 105, and is configured to seal the gap between the atomizing core 50 and the second end 1053 of the liquid inlet channel 105. This prevents the aerosol generating matrix in the liquid storage chamber 31 from flowing directly into the atomizing channel 101 through the gap between the atomizing core 50 and the second end 1053 of the liquid inlet channel 105, thus preventing the aerosol generating matrix from being heated and atomized by the atomizing core 50. This reduces waste of the aerosol generating matrix and prevents it from entering the atomizing channel 101 and clogging the air inlet 104, thereby improving the stability and reliability of the aerosol generating device 1000. Furthermore, it prevents the aerosol generating matrix from leaking out of the atomizer 100 through the air inlet 104, thereby reducing the possibility of damage to other devices in the aerosol generating device 1000, extending the service life of the aerosol generating device 1000, and ensuring its normal operation.

[0083] More specifically, in some embodiments, a limiting surface is provided at the second end 1053 of the liquid inlet channel 105, and an abutment surface 503 abuts against the limiting surface. A sealing element 85 is provided between the abutment surface 503 and the limiting surface. The setting of the limiting surface facilitates the installation and positioning of the atomizing core 50 in the liquid inlet channel 105, thereby improving the assembly efficiency of the atomizing core 50 in the atomizing base 10.

[0084] It should be noted that, in some embodiments, the seal 85 may be made of at least one of the following materials: rubber, silicone, plastic and synthetic fiber. The rubber material includes, but is not limited to, natural rubber, fluororubber, polyurethane rubber, EPDM rubber or silicone rubber.

[0085] In some embodiments, a sealing member 87 is provided between the atomizing base 10 and the liquid storage component 30. The sealing member 87 is configured to seal the gap between the atomizing base 10 and the liquid storage component 30, so that the liquid inlet channel 105 forms a relatively closed passage, preventing the aerosol generating matrix in the liquid inlet channel 105 from leaking through the gap between the atomizing base 10 and the liquid storage component 30. This can reduce the waste of aerosol generating matrix on the one hand, and prevent the aerosol generating matrix from leaking to the outside of the atomizer 100 and causing damage to other components of the aerosol generating device 1000 on the other hand. Thus, the service life of the aerosol generating device 1000 is extended while ensuring the normal operation of the aerosol generating device 1000.

[0086] It should be noted that, in some embodiments, the closure 87 may be made of at least one of the following materials: rubber, silicone, plastic and synthetic fiber. The rubber material includes, but is not limited to, natural rubber, fluororubber, polyurethane rubber, EPDM rubber or silicone rubber.

[0087] Please see Figure 2 , Figure 3 and Figure 5 In some embodiments, the atomizing core 50 includes a contact member 53, a storage member 55, and a heating member 51 stacked in sequence. The contact member 53 is configured to abut against the sealing member 85, the storage member 55 is configured to absorb and store the aerosol generating matrix, and the heating member 51 is disposed on the heating surface 501 and configured to heat the aerosol generating matrix. The structural strength of the contact member 53 is greater than that of the storage member 55.

[0088] Thus, compared to the storage component 55 directly abutting against the sealing component 85, the setting of the abutting component 53 can improve the stability of the installation of the sealing component 85. That is, the abutting component 53 can effectively limit and fix the sealing component 85, reduce the possibility of the sealing component 85 shifting or falling off, and ensure the sealing effect of the sealing component 85.

[0089] It should be noted that, in some embodiments, the storage component 55 can be a liquid-retaining cotton; the material of the storage component 55 includes, but is not limited to, polypropylene, polyethylene, polyester fiber, and glass fiber. The contact surface 503 is the side of the contact component 53 opposite to the storage component 55.

[0090] In some embodiments, the atomizing core 50 may further include a substrate disposed between the storage element 55 and the heating element 51, and the substrate is at least used to mount the heating element 51. It should be noted that in some embodiments, the material of the substrate includes, but is not limited to, metal, ceramic (e.g., porous ceramic), glass, etc.
