[0037] The aerosol-generating device is a small device capable of acting on an aerosol-generating substrate by a heating technique and generating an aerosol. In the related art, the atomizer in the aerosol-generating device for the paste-state substrate includes a heating body capable of heating and atomizing the paste-state substrate to make the paste-state substrate generate an aerosol. However, before heating the paste-state substrate, the paste-state substrate needs to be preheated by a preheating circuit, resulting in a relatively complex structure of the heating body, which is not conducive to the miniaturization of the heating body. To solve the above problem, please refer to Figure 1 The embodiments of the present application provide a heating body 10, an atomizer 100 and an aerosol-generating device 1000.

[0038] Please refer to Figure 1 The aerosol-generating device 1000 provided by the embodiments of the present application includes an atomizer 100 and an electronic control assembly 300, and the atomizer 100 is electrically connected to the electronic control assembly 300.

[0039] It can be understood that the aerosol-generating device 1000 is a structure capable of generating an aerosol by heating an aerosol-generating substrate. The aerosol-generating substrate is a product that can generate an aerosol after being processed and heated. The aerosol-generating substrate can be in a liquid state, or in a full solid state or a semi-solid state. In some embodiments of the present application, the aerosol-generating substrate includes a paste-state substrate. It should be noted that the aerosol can be visible or invisible and can include vapor (e.g., fine particulate matter in a gaseous state, which is usually a liquid or a solid at room temperature) and gas and liquid droplets of condensed vapor.

[0040] In some embodiments, the electric control assembly 300 comprises a power supply unit and a controller. The power supply unit is configured to provide electric energy for the operation of the atomizer 100, so that the atomizer 100 can heat the aerosol generating substrate to form an aerosol. The controller is electrically connected to the power supply unit, and is configured to control the operation of the atomizer 100 (including the start and stop of the atomizer 100, the switching of the working mode, etc.). For example, when the aerosol generating device 1000 is being puffed, the controller can control the power supply unit to supply electric energy to the atomizer 100, so that the atomizer 100 can work and heat the aerosol generating substrate. When the user does not use the aerosol generating device 1000, the controller can control the power supply unit to stop supplying electric energy to the atomizer 100, so that the atomizer 100 does not heat the aerosol generating substrate. It should be noted that, in some embodiments, the power supply unit can be a dry battery, a rechargeable battery, or a capacitor, etc. The rechargeable battery includes but is not limited to a lithium ion battery, a nickel-hydrogen battery, a nickel-cadmium battery, etc.

[0041] Further, in some embodiments, the aerosol generating device 1000 further comprises a housing 500, and the electric control assembly 300 is arranged in the housing 500.

[0042] Specifically, the housing 500 is a structure that can accommodate and protect the electric control assembly 300 and other devices in the aerosol generating device 1000. The material of the housing 500 includes but is not limited to plastic, aluminum alloy, copper, iron, steel, carbon fiber composite material, etc. In some embodiments, the housing 500 can be made of plastic, so that the housing 500 is more lightweight, which is conducive to the lightweight of the aerosol generating device 1000. In other embodiments, the housing 500 can be made of aluminum alloy, so that the structural strength of the housing 500 is improved, the possibility of damage (such as deformation, etc.) of the housing 500 is reduced, and the normal work of the aerosol generating device 1000 is ensured.

[0043] In some embodiments, the aerosol generating device 1000 comprises the atomizer 100, and can have at least the same beneficial effects as the atomizer 100. Therefore, the beneficial effects of the aerosol generating device 1000 can refer to the beneficial effects of the atomizer 100 described below.

[0044] For example, Figures 1 to 3The atomizer 100 provided by the embodiment of the present application comprises a heating body 10. The heating body 10 is a device or material that can generate heat energy and transfer the heat energy to the aerosol generating substrate in the atomizer 100. Since the atomizer 100 in the embodiment comprises the heating body 10, it can be understood that the atomizer 100 at least comprises the same beneficial effects as the heating body 10. Therefore, the beneficial effects of the atomizer 100 are described below in the beneficial effects of the heating body 10.

[0045] Please refer to Figure 1 , and combine Figure 4 and Figure 5 , or Figure 6 and Figure 7 The heating body 10 provided by the embodiment of the present application comprises a storage member 11, a substrate 13 and a heating member 15. The storage member 11 is provided with a storage cavity 111 for storing the aerosol generating substrate. The substrate 13 comprises a porous layer 131 and a dense layer 133. The porous layer 131 is provided with a flow channel 1311 for the aerosol generating substrate to flow. The dense layer 133 and the storage member 11 are respectively arranged on opposite sides of the porous layer 131. The periphery of the substrate 13 extends beyond the periphery of the storage member 11. The dense layer 133 is used to prevent the aerosol generating substrate from flowing out from the side of the porous layer 131 connected to the dense layer 133. The heating member 15 is arranged on the substrate 13. The heating member 15 is used to heat the aerosol generating substrate, so that the aerosol generating substrate flows into the flow channel 1311 and generates aerosol.

[0046] The storage member 11 is an element in the heating body 10 for storing the aerosol generating substrate. The storage member 11 can be made of at least one of glass, ceramic, metal and the like. The cross-sectional shape of the storage cavity 111 can be a regular shape such as a square, a circle, a triangle, etc., or an irregular shape. The present application does not make any limitation.

[0047] The substrate 13 is a structure in the heating body 10 for loading elements other than the substrate 13. The elements other than the substrate 13 herein include but are not limited to the heating member 15 and the like. The outer contour shape of the substrate 13 can be a regular shape or an irregular shape. The regular shape herein includes but is not limited to a rectangle, a circle, a cylinder, a triangle, a polygon and the like. In the case where the outer contour shape of the substrate 13 is an irregular shape, the heating body 10 can adapt to the structural layout of the atomizer 100, facilitating the compact arrangement of other components. In some embodiments of the present application, the periphery of the substrate 13 extends beyond the periphery of the storage member 11, that is, the cross-sectional size of the substrate 13 is larger than the cross-sectional size of the storage member 11. In this way, on the one hand, it can facilitate the substrate 13 to load the heating member 15 and other structural members; on the other hand, it can ensure that the aerosol generating substrate in the storage member 11 flows smoothly into the substrate 13, improving the stability and reliability of the heating body 10.

[0048] In some embodiments, the storage element 11 includes a sidewall extending to one side from the base 13, the sidewall and the base 13 forming a storage cavity 111, the periphery of the base 13 extending out of the periphery of the sidewall.

[0049] Specifically, in some embodiments, the storage member 11 includes a sidewall extending vertically to one side from the base 13; that is, the base 13 includes a first side facing away from it. Figure 4 The upper side of the matrix 13) and the second side ( Figure 4 The storage member 11 includes a sidewall extending vertically from a first side of the substrate 13 toward a second side away from the substrate 13, and the sidewall and the substrate 13 together form a storage cavity 111. In some embodiments of this application, the storage cavity 111 stores a paste-like aerosol-generating matrix.

[0050] More specifically, in some embodiments, an opening is provided at one end of the sidewall away from the substrate 13, and the opening communicates with the storage cavity 111. The opening facilitates the replenishment of the aerosol generation matrix, ensuring the normal operation of the aerosol generation device 1000.

[0051] The porous layer 131 is made of at least one of metal, ceramic, and glass; it can also be a composite material of various materials. In some embodiments of this application, the porous layer 131 is porous ceramic, and the flow channel 1311 includes micropores in the porous layer 131. The porous ceramic is typically prepared by mixing a ceramic slurry with a pore-forming agent and then sintering it, resulting in a large number of micropores within the sintered ceramic body. In some embodiments, the micropores can serve as the flow channel 1311 of the atomizing matrix in the porous layer 131, enabling the porous layer 131 to absorb and conduct the aerosol generating matrix. It should be noted that in some embodiments, multiple micropores can be interconnected, thereby enabling the storage and conduction of the aerosol generating matrix to a certain extent, thus ensuring the normal operation of the heating element 10. It is understood that in other embodiments, the flow channel 1311 may also include other artificially created channels.

[0052] The aerosol generating substrate in the storage cavity 111 can enter the flow channel 1311 of the porous layer 131 by the gravity of the aerosol generating substrate, the capillary force of the porous layer 131, the negative pressure formed in the atomizer 100 during puffing, or the like. In the case of a long single puffing time of a user, the aerosol generating substrate in the flow channel 1311 can be completely consumed, and if the user puffs again without timely supplementing the aerosol generating substrate, the heating body 10 can be dry-burned due to the lack of aerosol generating substrate. Therefore, compared with the case where the storage cavity 111 is not arranged, the arrangement of the storage cavity 111 can ensure that the aerosol generating substrate can be supplemented at any time, prevent the problem of dry burning caused by the lack of aerosol generating substrate during puffing, and improve the puffing experience of the user.

[0053] In addition, since the low-temperature atomization effect of the paste-like substrate is best, in the case where the porous layer 131 is a porous ceramic, the heating body 10 can utilize the feature that the porous ceramic can be atomized at a low temperature on the front side to improve the atomization effect of the paste-like substrate and ensure the puffing taste of the user.

[0054] The material of the dense layer 133 is at least one of metal, ceramic, and glass, and the material of the dense layer 133 can also be a composite material of various materials. In some embodiments of the present application, the dense layer 133 is dense ceramic. The dense ceramic can be made of at least one of aluminum nitride, silicon carbide, aluminum oxide, zirconium oxide, and silicon nitride. The dense layer 133 can seal the flow channel 1311 to prevent the aerosol generating substrate in the flow channel 1311 from flowing out from the side connected to the porous layer 131, thereby on the one hand, ensuring that the porous layer 131 has sufficient aerosol generating substrate and reducing the possibility of dry burning caused by the lack of aerosol generating substrate during puffing, and on the other hand, preventing the leaked aerosol generating substrate from contacting the electronic control assembly 300 to cause damage to the electronic control assembly 300, prolonging the service life of the electronic control assembly 300, and improving the safety performance of the atomizer 100.

[0055] In addition, since the dense ceramic has good heat insulation, the arrangement of the dense layer 133 can also prevent the heat generated by the heating element 15 from being dissipated to the external structure, thereby reducing heat loss, allowing more heat generated by the heating element 15 to act on the aerosol generating substrate, and thus improving the thermal efficiency of the heating body 10, reducing the energy consumption of the aerosol generating device 1000, and prolonging the endurance time of the aerosol generating device 1000.

[0056] In some embodiments, the porous layer 131 and the storage device 11 are an integral structure, that is, the porous layer 131 and the storage device 11 are an integral structure manufactured by an integral molding process. This can improve the bonding strength between the porous layer 131 and the storage device 11, prevent the porous layer 131 and the storage device 11 from separating during the operation of the heating element 10, and improve the stability and reliability of the operation of the heating element 10. In other embodiments, the porous layer 131 and the storage device 11 are separate structures, that is, the porous layer 131 and the storage device 11 are two different structures. The connecting surfaces of the porous layer 131 and the storage device 11 can be joined together by a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, bolt connections or snap-fit ​​connections; non-detachable connection methods include, but are not limited to, adhesive or welding.

[0057] The heating element 15 is a structure in the heating body 10 used to heat the aerosol-generating matrix. The heating element 15 includes, but is not limited to, heating circuits, heating films, heating sheets, heating wires, and heating meshes. The heating element 15 can be made of at least one of the following materials with appropriate impedance: metallic materials, metal alloys, graphite, carbon, conductive ceramics, tin-antimony oxide, other ceramic materials, and composite materials of metallic materials. Suitable metallic or alloy materials include at least one of nickel, cobalt, zirconium, titanium, nickel alloys, cobalt alloys, zirconium alloys, titanium alloys, nickel-chromium alloys, nickel-iron alloys, iron-chromium alloys, iron-chromium-aluminum alloys, titanium alloys, iron-manganese-aluminum based alloys, or stainless steel. In some embodiments of this application, the heating element 15 can heat the paste-like matrix in the storage cavity 111 to melt the paste-like matrix and allow it to flow into the flow channel 1311; and the heating element 15 can also heat the aerosol-generating matrix in the flow channel 1311 to generate aerosols from the aerosol-generating matrix.

[0058] In some embodiments, the heating element 15 can be disposed on the surface of the base 13, which facilitates the installation of the heating element 15 on the base 13 and improves the assembly efficiency of the heating element 10. In other embodiments, the heating element 15 can be embedded in the base 13, which on the one hand reduces the possibility of interference damage between the heating element 15 and the external structure, thereby extending the service life of the heating element 15 and ensuring the stability and reliability of the heating element 10; on the other hand, it reduces the space occupied by the heating element 15, which is conducive to the miniaturization of the heating element 10.

[0059] In the heating element 10 of this embodiment, the heating element 15 is disposed on the substrate 13. The heating element 15 is used to heat the aerosol generating matrix so that the aerosol generating matrix flows into the flow channel 1311 and generates aerosol. That is, the heat generated by the heating element 15 can be conducted to the storage unit 11 and heat the aerosol generating matrix in the storage unit 11 so that the aerosol generating matrix flows into the flow channel 1311. In addition, the heating element 15 can also heat the aerosol generating matrix in the flow channel 1311 so that the aerosol generating matrix generates aerosol. Thus, the heating element 15 can preheat the aerosol generating matrix through the storage unit 11 without the need for an additional preheating circuit, thereby simplifying the structure of the heating element 10 and facilitating the miniaturization of the heating element 10.

[0060] In some embodiments, the storage element 11 is made of the same material as the porous layer 131. For example, when the porous layer 131 is made of at least one of metal, ceramic, and glass, the storage element 11 is also made of at least one of metal, ceramic, and glass.

[0061] Specifically, in some embodiments, the storage element 11 is a porous ceramic, and the storage element 11 includes a first end and a second end opposite to each other, with the first end of the storage element 11 connected to the porous layer 131. In one example, the storage cavity 111 extends through the first end and the second end of the storage element 11, so that the aerosol generating matrix in the storage cavity 111 can directly contact the porous layer 131, thereby facilitating the flow of the aerosol generating matrix in the storage cavity 111 into the flow channel 1311 of the porous layer 1311. In another example, the storage cavity 111 is recessed from the second end of the storage element 11 toward the first end of the storage element 11, and the bottom wall of the storage cavity 111 is spaced apart from the first end of the storage element 11. In this case, the aerosol generating matrix in the storage cavity 111 can flow into the flow channel 1311 of the porous layer 1311 through the micropores inside the storage element 11.

[0062] In other embodiments, the storage element 11 is made of the same material as the dense layer 133. For example, when the dense layer 133 is made of at least one of metal, ceramic, and glass, the storage element 11 is also made of at least one of metal, ceramic, and glass.

[0063] Specifically, in some embodiments, the storage element 11 is a dense ceramic, and the storage element 11 includes a first end and a second end opposite to each other, with the first end of the storage element 11 connected to the porous layer 131. The storage cavity 111 extends through the first end and the second end of the storage element 11, thus allowing the aerosol generating matrix in the storage cavity 111 to directly contact the porous layer 131, thereby facilitating the flow of the aerosol generating matrix in the storage cavity 111 into the flow channel 1311 of the porous layer 131.

[0064] Please combineFigure 4 and Figure 5 In some embodiments, the heating element 15 is disposed on the side of the dense layer 133 opposite to the porous layer 131. Therefore, the aerosol-generating matrix in the porous layer 131 cannot come into contact with the heating element 15. This prevents metal from the heating element 15 from precipitating into the aerosol-generating matrix, ensuring safety when the aerosol is generated and inhaled by the user. It also prevents corrosion of the heating element 15, extending its service life and ensuring the stability and reliability of the heating element 10. Furthermore, it prevents the aerosol generated by the aerosol-generating matrix from contacting the heating element 15, avoiding the condensation of aerosols on the heating element 15 to form charred material, thereby improving the user's inhalation experience.

[0065] Please combine Figure 6 and Figure 7 In other embodiments, the heating element 15 is disposed on the side of the porous layer 131 opposite to the dense layer 133, and located outside the periphery of the storage unit 11. This allows the heating element 15 to be closer to the aerosol generating matrix, enabling it to directly heat the aerosol generating matrix with faster heat transfer efficiency. This increases the heating rate of the aerosol generating matrix, allowing it to reach the atomization temperature more quickly, reducing suction waiting time and generating aerosol faster, thus ensuring a better suction experience for the user. It should be noted that the heating element 15 being located outside the periphery of the storage unit 11 can also mean that the heating element 15 is disposed on the porous layer 131 and surrounds the storage unit 11. Therefore, the heat generated by the heating element 15 can act on the storage unit 11 more quickly, causing the aerosol generating matrix in the storage unit 11 to flow into the flow channel 1311 and be heated and atomized to generate aerosol.

[0066] Please see Figure 1 and combined Figure 4 and Figure 5 ,or Figure 6 and Figure 7 In some embodiments, the heating element 15 may include a heating part 151 and an electrode part 153 (including a positive electrode part and a negative electrode part), the heating part 151 and the electrode part 153 are electrically connected, and the electrode part 153 is used to conduct electrical energy to the heating part 151 so that the heating part 151 generates heat.

[0067] Specifically, the electrode portion 153 can be electrically connected to the electronic control component 300 (power supply unit). Thus, the electrical energy of the electronic control component 300 can be transferred to the heating portion 151 through the electrode portion 153, causing the heating portion 151 to generate heat and heat the aerosol generating matrix. It should be noted that in some embodiments, the electrode portion 153 can be sheet-like, columnar, porous powder, etc., and is not limited thereto. When the electrode portion 153 is sheet-like, it can be connected to the heating portion 151 by embedding, plugging, or other methods to conduct the electrical energy of the electronic control component 300 to the heating portion 151, thereby causing the heating portion 151 to generate heat.

[0068] In some embodiments, the heating element 10 further includes a conductive element 17 electrically connected to the heating element 15. One end of the conductive element 17 is electrically connected to the heating element 15, and the other end extends from the base 13 in a direction away from the storage element 11 and is used to connect to an external power supply device (e.g., a power supply unit).

[0069] Specifically, in some embodiments, the conductive element 17 is used to transfer electrical energy to the heating element 15, so that the heating element 15 heats up and heats the aerosol to generate a matrix. There are two conductive elements 17, both of which are electrically connected to the heating element 15 (the two electrode portions 153 of the heating element 15) and can form a circuit loop together with the electronic control assembly 300. For example, when both conductive elements 17 are electrically connected to the electronic control assembly 300, the electrical energy of the electronic control assembly 300 can flow to the heating element 15 through one of the two conductive elements 17 to generate heat in the heating element 15 (the heating portion 151 of the heating element 15), and the electrical energy can flow back from the heating element 15 to the electronic control assembly 300 through the other of the two conductive elements 17.

[0070] Please see Figures 1 to 3 In some embodiments, the atomizer 100 further includes an atomizing base 20 and a heat insulation component 30. The atomizing base 20 is used to hold the heating element 10. The heat insulation component 30 is connected to the atomizing base 20 and is used to prevent the heat from the heating element 10 from being transferred to the outside.

[0071] The atomizer base 20 is a structure in the atomizer 100 that serves as a mounting and connecting element. The materials of the atomizer base 20 include, but are not limited to, plastics, aluminum alloys, copper, iron, steel, carbon fiber composites, polyetheretherketone (PEEK) materials, high-melting-point metals, and high-temperature resistant ceramics. In some embodiments of this application, the outer peripheral wall of the atomizer base 20 is provided with threads, which are configured to connect with the housing 500 to achieve electrical connection between the electronic control assembly 300 and the atomizer 100.

[0072] The heat insulation component 30 is a structure in the atomizer 100 that prevents heat dissipation from the heating element 10. Specifically, the heat insulation component 30 prevents the heat generated by the heating element 15 from dissipating to the outside. This reduces heat loss, allowing more of the heat generated by the heating element 15 to act on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element 15, reducing the energy consumption of the aerosol generating device 1000, and extending its runtime. Furthermore, it reduces the likelihood of heat dissipating to other structural components of the aerosol generating device 1000, lowering the external wall temperature of the aerosol generating device 1000, resulting in a better user experience.

[0073] Furthermore, in some embodiments, the heat insulation component 30 includes a heat insulation element 31, which is connected to the atomizing seat 20 and is disposed around the outside of the heating element 10. The heat insulation element 31 is used to prevent the heat of the heating element 10 from being transferred to the outside. It should be noted that in some embodiments, the heat insulation element 31 may be made of a material with low thermal conductivity, such as zirconia ceramic or PEEK.

[0074] The heat insulation component 31 not only prevents the heat generated by the heating element 15 from dissipating to the outside, reducing heat loss, improving the thermal efficiency of the heating element 15, and enhancing the user experience, but also serves as the main supporting structure of the atomizer 100, playing a supporting and fixing role, and ensuring the stability and reliability of the overall structure of the atomizer 100.

[0075] In some embodiments, the heat insulation component 30 further includes a reflector 33, which is disposed on the side of the heat insulation component 31 facing the heating element 10. The reflector 33 is used to reflect the heat dissipated from the heating element 10 back to the heating element 10. The reflector 33 can perform secondary radiation of the dissipated heat, allowing more heat to act on the aerosol generating matrix, reducing energy loss, thereby improving the thermal efficiency of the heating element 15, reducing the energy consumption of the aerosol generating device 1000, and extending the operating time of the aerosol generating device 1000. It should be noted that in some embodiments, the reflector 33 can be a gold-plated stainless steel component, or other structural components capable of reflecting heat.

[0076] It should be noted that, in some embodiments, both the heat insulation element 31 and the reflective element 33 can be tubular structures, that is, both the heat insulation element 31 and the reflective element 33 can be hollow columnar structures, with the reflective element 33 disposed on the inner wall surface of the heat insulation element 31. In some embodiments, the reflective element 33 and the heat insulation element 31 can be joined together by a non-detachable connection method; the non-detachable connection method includes, but is not limited to, bonding, welding, and interference fit. In other embodiments, the reflective element 33 and the heat insulation element 31 can be joined together by a detachable connection method; the detachable connection method includes, but is not limited to, snap-fit ​​connection or bolt connection.

[0077] In some embodiments, the heat insulation component 30 further includes a decorative tube 35, which is connected to the atomizing base 20, and a heat insulation element 31 is disposed on the inner wall of the decorative tube 35. That is, the heat insulation element 31 can be connected to the atomizing base 20 through the decorative tube 35. It should be noted that in some embodiments, the material of the decorative tube 35 can be a metallic material and / or a non-metallic material. The metallic material includes, but is not limited to, aluminum, iron, steel, or aluminum alloys, and the non-metallic material includes, but is not limited to, plastics.

[0078] Specifically, in some embodiments, the decorative tube 35 and the atomizing base 20 can be connected together by means of interference fit, bonding, welding, or snap-fit ​​connection; similarly, the decorative tube 35 and the heat insulation component 31 can also be connected together by means of interference fit, bonding, welding, or snap-fit ​​connection. The decorative tube 35 can, on the one hand, prevent the user from directly seeing the heat insulation component 31 or other structural components inside the heat insulation component 31, thereby reducing visual defects and improving the aesthetics of the atomizer 100; on the other hand, it can protect the heat insulation component 31 and other structural components inside the heat insulation component 31, thereby extending the service life of the atomizer 100 and improving the stability and reliability of the atomizer 100's operation.

[0079] Cleansing Figure 3 In some embodiments, the atomizer 100 further includes a first barrier 41, which is disposed around the outer side of the porous layer 131 and connected to the outer peripheral wall of the porous layer 131. The first barrier 41 is used to prevent the aerosol generation matrix from flowing out from the outer peripheral wall of the porous layer 131. It should be noted that in some embodiments, the first barrier 41 can be a metallic or non-metallic material. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. For example, the first barrier 41 can be a quartz tube.

[0080] The first barrier 41 acts as a seal to prevent the aerosol generating matrix in the flow channel 1311 from flowing out from the outer peripheral wall of the porous layer 131 (the side of the porous layer 131 connected to the first barrier 41). This ensures that there is a sufficient amount of aerosol generating matrix in the porous layer 131, reducing the possibility of dry burning due to insufficient aerosol generating matrix during the inhalation process and improving the user's inhalation experience. On the other hand, it prevents the leaked aerosol generating matrix from contacting the electronic control component 300 and causing damage to the electronic control component 300, extending the service life of the electronic control component 300 and improving the safety performance of the atomizer 100.

[0081] In some embodiments, the first barrier 41 can be a tubular structure, that is, the first barrier 41 has a cavity. The cavity of the first barrier 41 communicates with the storage cavity 111, and the cavity of the first barrier 41 stores an aerosol generating matrix (paste-like matrix). Therefore, the first barrier 41 allows the aerosol generating matrix in the storage cavity 111 to be replenished at any time, preventing insufficient aerosol generating matrix during suction and thus preventing dry burning, improving the user's suction experience.

[0082] In some embodiments, the atomizer 100 further includes a second barrier 43, which includes a first sub-part and a second sub-part connected to each other. The first sub-part is disposed on the side of the dense layer 133 opposite to the porous layer 131, and the second sub-part is disposed around the outside of the dense layer 133 and the first barrier 41. The second barrier 43 is used to connect the heating element 10 and the first barrier 41.

[0083] Specifically, in some embodiments, the second barrier 43 may be made of a material with low thermal conductivity, such as zirconia ceramic or PEEK. Thus, the second barrier 43 can also prevent heat from the heating element 10 from dissipating to external structures (such as the atomizing seat 20), thereby reducing heat loss and improving the thermal efficiency of the heating element 10.

[0084] Please see Figure 3 In some embodiments, the atomizer 100 has an atomizing air passage 101 for contacting outside air with the heating element 10 to generate aerosols from the aerosol generating matrix.

[0085] Furthermore, in some embodiments, the atomizing base 20 is provided with an electrical connector 50, which is electrically connected to the heating element 10. The electrical connector 50 is provided with a first channel 51, and the heat insulation component 31 of the heat insulation component 30 is provided with a second channel 311. There is a gap channel 331 between the reflector 33 of the heat insulation component 30 and the first barrier component 41. The first barrier component 41 is provided with a connecting hole 413, which is used to connect the gap channel 331 and the inner cavity 411 of the first barrier component 41. The first channel 51, the second channel 311, the gap channel 331, the connecting hole 413 and the inner cavity 411 of the first barrier component 41 are connected in sequence to form the atomizing airway 101.

[0086] Specifically, please combine Figure 8 In some embodiments, when the atomizer 100 and the electronic control assembly 300 are electrically connected, the electrical connector 50 is used to connect the conductive element 17 and the power supply unit. When the aerosol generating device 1000 is drawn in, the electrical energy of the power supply unit is transferred to the heating element 15 through the electrical connector 50 and the conductive element 17, so that the heating element 15 is energized and heats the aerosol generating matrix, thereby melting the aerosol generating matrix in the storage cavity 111 and flowing into the flow channel 1311 of the porous layer 131; at the same time, outside air can flow into the inner cavity 411 of the first barrier 41 through the first channel 51, the second channel 311, the gap channel 331 and the connecting hole 413 in sequence and come into contact with the heating element 10 (e.g., Figure 8 (As indicated by the arrow in the image), thereby enabling the aerosol generating matrix in the flow channel 1311 to generate aerosols for the user to draw in when heated.

[0087] In some embodiments, the atomizing base 20 has a through hole, and the electrical connector 50 is installed in the through hole by a fixing member. It should be noted that in some embodiments, the fixing member can be made of at least one of the following materials: rubber, silicone, plastic, or synthetic fiber. The rubber material includes, but is not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber.

[0088] In some embodiments, the atomizer 100 further includes a suction member 60, which is connected to the heat insulation member 30 and communicates with the atomizing air passage 101.

[0089] The suction device 60 is used by the user to inhale the aerosol in the atomizing airway 101. For example, the suction device 60 may include a cooling section and a filtering section. The cooling section is connected to the heat insulation component 30, and the filtering section is located at the end of the cooling section opposite to the heat insulation component 30. The cooling section and the filtering section are connected, allowing the user to inhale through the filtering section to draw the generated aerosol into their mouth. The aerosol's temperature decreases as it passes through the cooling section to prevent the user from inhaling excessively hot aerosol. The filtering section filters out some impurities, preventing the user from inhaling impurities and improving the user's inhalation experience.

[0090] Specifically, in some embodiments, a sealing member 70 is provided between the suction member 60 and the first barrier member 41. The sealing member 70 is used to seal the gap between the suction member 60 and the first barrier member 41 to prevent aerosol in the atomizing airway 101 from leaking to the outside through the gap between the suction member 60 and the first barrier member 41. The sealing member 70 is provided with a third channel 71, which communicates with the inner cavity 411 of the first barrier member 41. The third channel 71 is configured to participate in the formation of the atomizing airway 101.

[0091] It should be noted that, in some embodiments, the seal 70 may be made of at least one of the following materials: rubber, silicone, plastic, or synthetic fiber. The rubber material includes, but is not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber.

[0092] In some embodiments, the sealing element 70 is connected to the suction element 60 via a connector 80. In some embodiments of this application, the connector 80 may be made of a magnetic material. The heat insulation element 31 is provided with a magnetic element 90, which is used to cooperate with the connector 80 to connect the suction element 60 to the heat insulation element 30. That is, the connection between the suction element 60 and the heat insulation element 30 is a magnetic connection, which makes it easy for the user to remove and replace the suction element 60, improving the user experience. In addition, when the user needs to replace or add aerosol generating matrix in the heating element 10, the user can remove the suction element 60 to expose the storage cavity 111 to the outside, so that the user can replace or add aerosol generating matrix into the storage cavity 111. After the user has completed the replacement or addition of aerosol generating matrix, the user can reconnect the suction element 60 and the heat insulation element 30.
