[0054] This application provides an atomizing core 10 for contacting and atomizing an aerosol generating matrix. (See reference...) Figure 1 The atomizing core 10 includes a liquid guide 11 and a heating element 13.

[0055] The liquid guiding zone 11 includes a first liquid guiding zone 111, a second liquid guiding zone 112, and at least one partition zone.

[0056] At least one partition separates the first fluid-conducting zone 111 from the second fluid-conducting zone 112 to isolate the two fluids.

[0057] The heating element 13 includes at least one first electrode portion 131, a heating portion 132, and a second electrode portion 133. The heating portion 132 is electrically connected to at least one first electrode portion 131 and at least one second electrode portion 133. The heating portion 132 includes a first heating sub-part 134 and a second heating sub-part 135. The first heating sub-part 134 is disposed corresponding to the first liquid guiding area 111, and the second heating sub-part 135 is disposed corresponding to the second liquid guiding area 112. The first electrode portion 131 is used to be electrically connected to the first electrode component 40 of the atomizer 80, and the second electrode portion 133 is used to be electrically connected to the second electrode component 50 of the atomizer 80.

[0058] The aerosol generation matrix is ​​a fluid medium.

[0059] The first liquid guiding zone 111 and the second liquid guiding zone 112 cannot exchange aerosol generation matrix with each other due to the obstruction of the separating zone 12.

[0060] The first electrode portion 131 and the second electrode portion 133 are electrically connected to the first power supply assembly 60. The first electrode portion 131 and the second electrode portion 133 are electrically connected via the heating portion 132, causing a current to form within the heating element 13. Due to the resistance of the heating portion 132 itself, the heating portion 132 generates heat to atomize the aerosol generation matrix of the conductive liquid 11. Specifically, the first heating element 134 can heat the aerosol generation matrix within the first conductive liquid region 111, and the second heating element 135 can heat the aerosol generation matrix within the second conductive liquid region 112.

[0061] The second electrode portions 133 on each of the liquid-conducting regions 11 are connected in parallel and share the first electrode portion 131 to form their own independent current circuits, so that the first heating element portion 134 and the second heating element portion 135 can selectively generate heat independently, thereby independently atomizing the aerosol generation matrix in the first liquid-conducting region 111 and the second liquid-conducting region 112.

[0062] In this embodiment, the atomizing core 10, by setting the partition area 12, is beneficial to reduce the overall external outline size of the atomizing core 10 while realizing the generation matrix of different types of aerosols in part or all of the guiding liquid 11, making the structure of the atomizing core 10 more compact and improving the adaptability of the atomizing core 10.

[0063] It is understood that the first electrode portion 131 is located outside the range of the first liquid guiding region 111 and outside the range of the second liquid guiding region 112.

[0064] In some embodiments, see Figure 1 The first electrode portion 131 is provided in the partition area 12.

[0065] In some embodiments, the first heating element 134 contacts the first liquid guiding region 111 in order to improve the efficiency of atomizing the aerosol generation matrix in the first liquid guiding region 111.

[0066] In some embodiments, the second heating element 135 contacts the second liquid guiding region 112 in order to improve the efficiency of atomizing the aerosol generation matrix in the second liquid guiding region 112.

[0067] In some embodiments, the number of second electrode portions 133 is at least two, at least one second electrode portion 133 is located in the first liquid guiding region 111 so that the first heating element 134 generates current, and at least one second electrode portion 133 is located in the second liquid guiding region 112 so that the second heating element 135 generates current.

[0068] It is understood that the first liquid guiding zone 111 and the second liquid guiding zone 112 are respectively provided with a liquid absorption surface 11a and an atomizing surface 11b. The liquid absorption surface 11a is used to contact the aerosol generation matrix, and the liquid absorption surface 11a and the atomizing surface 11b are in fluid communication.

[0069] The liquid-absorbing surface 11a is in contact with the aerosol-generating matrix, allowing the aerosol-generating matrix to enter the guiding liquid 11. The liquid-absorbing surface 11a is in fluid communication with the atomizing surface 11b, allowing the aerosol-generating matrix to pass through the guiding liquid 11 and reach the atomizing surface 11b.

[0070] It is understandable that the atomizing surface 11b of the first liquid guiding region 111 is in contact with the first heating element 134, and the atomizing surface 11b of the second liquid guiding region 112 is in contact with the second heating element 135.

[0071] It is understandable that the liquid absorption surface 11a of the first liquid guiding zone 111 and the liquid absorption surface 11a of the second liquid guiding zone 112 can respectively contact different types of aerosol generation matrices.

[0072] In some embodiments, see Figure 1 The liquid-absorbing surface 11a and the atomizing surface 11b are located on opposite sides of the liquid-conducting surface 11 along the first direction, so that the liquid-conducting surface 11 can absorb more aerosol to generate a matrix.

[0073] The number of heating elements 132 and the number of second electrode elements 133 are corresponding, and their specific number is not limited, such as two, three, four, five, six, etc.

[0074] The partition 12 can be a solid structure located between the two liquid conductors 11 to directly block the aerosol generation matrix from flowing directly between them, or it can be a spacer between the two liquid conductors 11.

[0075] In some embodiments, at least one of the first liquid guiding region 111 and the second liquid guiding region 112 is made of a porous material, and the separating region is made of a dense material.

[0076] This allows the first liquid-conducting zone 111 and the second liquid-conducting zone 112 to absorb the aerosol-generating matrix, while the separating zone restricts the flow of the aerosol-generating matrix within it.

[0077] Porous materials refer to materials that have a large number of pores. Several pores are interconnected to form channels through which liquids flow, and the aerosol generation matrix can flow within these channels.

[0078] Dense materials refer to materials that have fewer or no pores compared to porous materials, making it difficult or impossible for the aerosol generation matrix to pass through the separation zone.

[0079] It is understandable that porous materials and dense materials can be different materials or the same material, and porous materials are more porous than dense materials.

[0080] Porous materials can include any suitable material or combination of materials that the float-forming matrix can permeate and allow the float-forming matrix to migrate from the reservoir to the evaporator. The material or combination of materials is inert relative to the float-forming matrix. Porous materials can be capillary materials or may not be capillary materials. Porous materials can include hydrophilic materials to improve the distribution and diffusion of the float-forming matrix. This can contribute to the consistent formation of float. Particularly preferred materials will depend on the physical properties of the float-forming matrix. Examples of suitable materials are capillary materials, such as sponges, foam materials, ceramic-based or graphite-based materials in the form of fibers or sintered powders, foam metals, plastic materials, fibrous materials, or ceramics, wherein fibrous materials can be made from virgin or pressed fibers, including cellulose acetate fibers, polyester fibers, or bonded polyolefin fibers, polyethylene fibers, polyester fibers or polypropylene fibers, nylon fibers, etc. Porous materials can have any suitable porosity to be used with different liquid physical properties.

[0081] In some embodiments, see Figure 2 The material of the partition 12 is the same as that of the liquid guide 11. The liquid guide 11 is provided with a through liquid guide hole 11c. A part of the liquid guide hole 11c forms the first liquid guide area 111, and the other part of the liquid guide hole 11c forms the second liquid guide area 112.

[0082] In other words, the aerosol generating matrix itself cannot pass through the solid structure of the liquid guiding 11. It can only enter the liquid guiding hole 11c through the opening of the liquid guiding hole 11c and pass through the liquid guiding hole 11c to reach the other end opening of the liquid guiding hole 11c so as to contact the first heating element 134 and the second heating element 135 respectively.

[0083] Thus, the material of the dividing zone 12 and the liquid guide 11 is the same, which helps to simplify the manufacturing process of the atomizing core 10 and reduce manufacturing costs.

[0084] It is understood that at least a portion of at least one of the second electrode portion 133 and the heating portion 132 covers the opening of the liquid guiding hole 11c located on the atomizing surface 11b, so that the heating element 13 can directly contact the aerosol generating matrix in the liquid guiding hole 11c, thereby improving the atomization efficiency.

[0085] In some embodiments where the material of the partition 12 is the same as the material of the liquid guiding 11, see [reference needed]. Figure 2 The first liquid guiding area 111, the second liquid guiding area 112 and the partition area 12 are an integral structure. That is to say, the liquid guiding area 11 and the partition area 12 are different parts of the same component. This helps to further simplify the structure of the atomizing core 10 and reduce the number of parts.

[0086] In some embodiments where the material of the partition region 12 is the same as the material of the liquid conductor 11, the materials of the liquid conductor 11 and the partition region 12 can be dense ceramic materials, glass materials, etc.

[0087] In some embodiments, the density of the material in the partition region 12 is greater than the density of the material in the liquid conductor 11.

[0088] The liquid guide 11 has a large number of pores, which are interconnected to form a channel connecting the atomizing surface 11b and the liquid absorption surface 11a.

[0089] The density of the material in the separating region 12 is greater than that of the material in the conductive liquid 11. In other words, the separating region 12 can be a porous material. However, the volume occupied by the pores in the separating region 12 per unit volume is less than that occupied by the pores in the conductive liquid 11. This prevents the pores in the separating region 12 from forming a channel connecting the two conductive liquids 11, thereby blocking the flow of the aerosol-generating matrix between the two conductive liquids 11.

[0090] The material of the liquid-conducting zone 11 can be fiber material, porous ceramic, etc., and the material of the separating zone 12 can be dense ceramic material, glass material, etc.

[0091] Porous ceramic materials are generally ceramic materials sintered at high temperatures from components such as aggregates, binders, and pore-forming agents. They have a large number of interconnected pores that communicate with the material surface. Porous ceramic materials possess excellent properties such as high porosity, stable chemical properties, large specific surface area, low bulk density, low thermal conductivity, and resistance to high temperatures and corrosion.

[0092] It is understandable that the first electrode part 131, the heating part 132, and the second electrode part 133 are all made of conductive materials, and the conductive materials used can be metallic materials.

[0093] The heating element 13 can be formed by screen printing and sintering a paste containing a metal material, or by plating a metal material. The metal material can contain one or more elements such as Ag, Cu, Au, Ni, W, Ru, and Fe. Specifically, the heating element 13 can be formed by screen printing a paste of metal material onto the atomizing surface 11b of the liquid guide 11 and then sintering it.

[0094] In some embodiments where the fluid-conducting 11 and the partition 12 are independent components, the specific shape of the fluid-conducting 11 is not limited, such as a cube, cuboid, cylinder, prism, etc.; the specific shape of the partition 12 is not limited, such as a cube, cuboid, cylinder, prism, etc. The shapes of the fluid-conducting 11 and the partition 12 can be the same or different.

[0095] In some embodiments, the first liquid guiding region 111, the second liquid guiding region 112, and the partition region 12 are separate structures, that is, the first liquid guiding region 111, the second liquid guiding region 112, and the partition region 12 are each independent components, and the three are fixed together to form the liquid guiding region 11.

[0096] The specific way in which the first liquid guiding zone 111 and the second liquid guiding zone 112 are fixed to the partition zone 12 is not limited.

[0097] In some embodiments, see Figure 3 At least one of the first liquid guiding area 111 and the second liquid guiding area 112 is provided with a first mounting part 11d, and the partition area 12 is fixedly engaged with the first mounting part 11d.

[0098] Thus, the first mounting part 11d achieves the purpose of fixing at least one of the first liquid guiding area 111 and the second liquid guiding area 112 to the partition area 12.

[0099] In some embodiments, see Figure 3 The first mounting part 11d is a first mounting protrusion, and the partition area 12 is provided with a first mounting groove. The inner wall of the first mounting groove and the first mounting protrusion are interference fit to achieve fixation.

[0100] In some embodiments, see Figure 3 The partition 12 is provided with a second mounting part 121, and at least one of the first liquid guiding area 111 and the second liquid guiding area 112 is fixedly engaged with the second mounting part 121.

[0101] Thus, the second mounting part 121 achieves the purpose of fixing at least one of the first liquid guiding area 111 and the second liquid guiding area 112 to the partition area 12.

[0102] In some embodiments, see Figure 3The second mounting part 121 is a second mounting protrusion. At least one of the first liquid guiding area 111 and the second liquid guiding area 112 is provided with a second mounting groove. The inner wall of the second mounting groove and the second mounting protrusion are interference fit to achieve fixation.

[0103] In some embodiments, see Figure 4 The partition 12 is provided with at least two first fixed cavities 12a spaced apart from each other. The first fixed cavity 12a is provided with an opening communicating with the outside of the liquid guiding 11. At least a portion of the first liquid guiding area 111 and at least a portion of the second liquid guiding area 112 are provided in different first fixed cavities 12a. The first heating element 134 cooperates with the first liquid guiding area 111 through the opening of one first fixed cavity 12a, and the second heating element 135 cooperates with the second liquid guiding area 112 through the opening of the other first fixed cavity 12a.

[0104] In this way, the positions of each liquid guide 11 are directly constrained and fixed by the inner walls of each first fixed cavity 12a, and the liquid guide 11 can be protected to a certain extent.

[0105] In some embodiments, the first fixed cavity 12a has two openings. The first liquid guiding region 111 or the second liquid guiding region 112 respectively cooperates with the first heating element 134 or the second heating element 135 through one opening, and the first liquid guiding region 111 or the second liquid guiding region 112 respectively absorbs aerosols to generate a matrix through the other opening. In some embodiments, the first fixed cavity 12a extends through the partition region 12 along a first direction to form two openings.

[0106] In some embodiments, at least one of the first liquid guiding region 111 and the second liquid guiding region 112 is completely located within the first fixed cavity 12a; in some embodiments, a portion of at least one of the first liquid guiding region 111 and the second liquid guiding region 112 is exposed outside the first fixed cavity 12a through an opening.

[0107] In some embodiments, the two openings of the first fixed cavity 12a are located on opposite sides of the first fixed cavity 12a along the first direction; in other embodiments, one opening is located on one side of the first fixed cavity 12a along the first direction, and the other opening is located on one side of the first fixed cavity 12a perpendicular to the first direction.

[0108] In some embodiments, the partition 12 is provided with a second fixed cavity, the second fixed cavity having an opening communicating with the outside of the liquid guiding 11. At least a portion of the first liquid guiding region 111 and at least a portion of the second liquid guiding region 112 are both located in the second fixed cavity and are spaced apart from each other. The first heating element 134 cooperates with the first liquid guiding region 111 through the opening of the second fixed cavity, and the second heating element 135 cooperates with the second liquid guiding region 112 through the opening of the second fixed cavity.

[0109] The first liquid guiding region 111 and the second liquid guiding region 112 are spaced apart from each other, thereby reducing the probability of different types of aerosol generation matrix flowing between the first liquid guiding region 111 and the second liquid guiding region 112.

[0110] Thus, the first liquid guiding area 111 and the second liquid guiding area 112 can be installed through only one second fixed cavity, which helps to simplify the structure of the atomizing core 10 and simplify the manufacturing process of the atomizing core 10.

[0111] In some embodiments, the first liquid guiding region 111, the second liquid guiding region 112, and the partition region 12 are bonded to each other.

[0112] Thus, the liquid guiding 11 and the partition area 12 are fixed by adhesive bonding, which is a simple method and helps to simplify the shape of the liquid guiding 11 and the partition area 12.

[0113] It is understood that the first heating element 134 is attached to the first liquid-conducting region 111, and the second heating element 135 is attached to the second liquid-conducting region 112. See some embodiments. Figure 1 , Figure 3 and Figure 4 The heating element 132 extends in a reciprocating, tortuous manner.

[0114] This increases the contact area between the heating element 132 and the liquid guide 11, further improving the efficiency of the atomizing core 10 in generating the atomized aerosol matrix.

[0115] In some embodiments, see Figure 1 , Figure 3 and Figure 4 Both the first heating element 134 and the second heating element 135 are connected to the same first electrode 131.

[0116] In this way, the first electrode 131 can supply power to both the first heating element 134 and the second heating element 135 simultaneously, which helps to simplify the manufacturing and assembly processes of the heating element 13.

[0117] In some embodiments, see Figure 5 There are multiple first electrode portions 131, and the multiple first electrode portions 131 are isolated from each other. The first heating element portion 134 and the second heating element portion 135 are electrically connected to different first electrode portions 131 respectively.

[0118] The isolation between the multiple first electrode portions 131 means that the individual first electrode portions 131 are not electrically connected to each other. It can mean that the individual first electrode portions 131 are spaced apart from each other and do not contact each other.

[0119] This reduces the probability of the first heating element 134 and the second heating element 135 being connected by current, thus ensuring that they always work synchronously.

[0120] In some embodiments, see Figure 1 The first liquid guiding region 111 is rectangular or cubic in shape; in some embodiments, see [reference needed]. Figure 1 The second liquid guiding region 112 is rectangular or cubic in shape; in some embodiments, see [reference needed]. Figure 1 The shape of the dividing area 12 is a cuboid or a cube.

[0121] In some embodiments, see Figure 1 and Figure 6 The first liquid guiding region 111, the second liquid guiding region 112, and the partition region 12 are arranged along the same straight line so that the outer contour of the liquid guiding region 11 is cuboid or cubic, making the outer contour of the liquid guiding region 11 regular, which is conducive to the arrangement and fixation of the liquid guiding region 11 within the atomizer 80. In some embodiments, the first liquid guiding region 111 and the second liquid guiding region 112 are symmetrically arranged with respect to at least one partition region 12.

[0122] In some embodiments, see Figure 7 The first liquid guiding region 111 is shaped like a fan-shaped cylinder; in some embodiments, see [reference needed]. Figure 1 The second liquid guiding region 112 is shaped like a fan-shaped cylinder; in some embodiments, see [reference needed]. Figure 1 The shape of the dividing area 12 is a fan-shaped column.

[0123] In some embodiments, see Figure 7 The first liquid guiding area 111, the second liquid guiding area 112 and the partition area 12 are arranged around each other so that the outer contour of the liquid guiding 11 forms a ring-shaped main structure, making the outer contour of the liquid guiding 11 regular, so as to facilitate the arrangement and fixation of the liquid guiding 11 in the atomizer 80.

[0124] In some embodiments, see Figure 1 The first liquid guiding region 111 and the second liquid guiding region 112 are arranged symmetrically about the dividing region 12. That is, the first liquid guiding region 111 and the second liquid guiding region 112 are symmetrical about a virtual plane passing through the geometric center of the dividing region 12.

[0125] In some embodiments, see Figure 7 and Figure 8 The first liquid guiding area 111 and the second liquid guiding area 112 are arranged symmetrically about the axis of the liquid guiding area 11, which facilitates the arrangement and installation of the first liquid guiding area 111 and the second liquid guiding area 112.

[0126] In some embodiments, see Figure 7 The axes of rotational symmetry of the first liquid-conducting region 111 and the second liquid-conducting region 112 are located outside the solid structure of the liquid-conducting region 11; in some embodiments, see [reference]. Figure 8The axis of rotational symmetry between the first liquid guiding zone 111 and the second liquid guiding zone 112 passes through the geometric center of the partition zone 12.

[0127] In some embodiments, see Figure 6 There are multiple partition zones 12, and one of the first liquid guiding zone 111 and the second liquid guiding zone 112 is provided between two adjacent partition zones.

[0128] This facilitates the atomization of various types of aerosol generation matrices.

[0129] In some embodiments, see Figure 6 The first liquid guiding area 111, the second liquid guiding area 112 and the multiple partition areas 12 are arranged alternately in a straight line. The arrangement is simple, the requirements for the outer contour of the liquid guiding area 11 are low, and it is easy to manufacture.

[0130] In some embodiments, see Figure 7 The first liquid guiding area 111, the second liquid guiding area 112 and the multiple partition areas 12 are arranged alternately and connected end to end to form a ring-shaped column structure. This helps to reduce the overall outer contour size of the atomizing core 10 and makes the structure of the atomizing core 10 more compact.

[0131] In some embodiments, see Figure 8 The first liquid guiding area 111 and the second liquid guiding area 112 are arranged around the periphery of the same partition area 12, which is beneficial for a single partition area 12 to cooperate with multiple first liquid guiding areas 111 and multiple second liquid guiding areas 112 at the same time, and is beneficial to reduce the overall outer contour size of the atomizing core 10, making the structure of the atomizing core 10 more compact.

[0132] It is understandable that in each of the first liquid guiding areas 111 and the second liquid guiding area 112 arranged around the periphery of the partition area 12, adjacent first liquid guiding areas 111 and second liquid guiding areas 112 are spaced apart from each other to reduce the probability of exchanging aerosols between them to form a matrix.

[0133] In some embodiments, see Figure 1 The area where the first liquid guiding area 111 contacts the second electrode part 133 is a first plane, and the area where the second liquid guiding area 112 contacts the second electrode part 133 is a second plane. The first plane and the second plane are coplanar, which helps to make the outer contour of the liquid guiding 11 regular and facilitates the installation and fixation of the liquid guiding 11.

[0134] In some embodiments, the first heating element 134 and the second heating element 135 are arranged on the same plane.

[0135] In some embodiments, see Figure 1The area where the separating region 12 contacts the first electrode portion 131 is a third plane. The first, second, and third planes are all coplanar. This facilitates a regular outer contour of the liquid-conducting 11, making its installation and fixation easier. See some embodiments. Figure 7 The areas where the first liquid guiding area 111 contacts the second electrode part 133, the areas where the second liquid guiding area 112 contacts the second electrode part 133, and the areas where the partition area 12 contacts the first electrode part 131 are all located on the same arc surface. This makes it easier to make the outer contour of the liquid guiding 11 regular and to install and fix the liquid guiding 11.

[0136] In some embodiments, see Figure 9 The partition 12 is provided with a first mounting hole that extends through the first direction. The first electrode part 131 is inserted into the first mounting hole. This makes it possible for both sides of the first electrode part 131 along the first direction to contact the first electrode part 40 of the atomizer 80 to achieve electrical connection, thereby improving the adaptability of the atomizer core 10 and making it easier to adapt to different arrangement positions of the first electrode part 40.

[0137] In some embodiments, see Figure 9 The first liquid guiding area 111 and the second liquid guiding area 112 are provided with a second mounting hole that extends through the first direction. The second electrode part 133 is inserted into the second mounting hole. This makes it possible for both sides of the second electrode part 133 along the first direction to contact the second electrode 50 of the atomizer 80 to achieve electrical connection, thereby improving the adaptability of the atomizing core 10 and making it easier to adapt to different arrangement positions of the second electrode 50.

[0138] This application also provides an atomizer 80, see reference. Figures 10 to 14 The atomizer 80 includes a mounting assembly 20 and an atomizing core 10 of any of the aforementioned embodiments. The mounting assembly 20 includes a mounting cavity and a plurality of liquid storage cavities 20a. The atomizing core 10 is disposed in the mounting cavity. The first liquid guiding area 111 and the second liquid guiding area 112 are respectively in fluid communication with a liquid storage cavity 20a.

[0139] The liquid storage chamber 20a is used to store the aerosol generation matrix.

[0140] It is understandable that the various liquid storage chambers 20a are isolated from each other so that each liquid storage chamber 20a stores different types of aerosol generation matrix.

[0141] The aerosol generating matrix in different liquid storage chambers 20a can contact the first liquid guiding region 111 and the second liquid guiding region 112 respectively, thereby enabling the liquid guiding region 11 to absorb the aerosol generating matrix. By using the atomizing core 10 in the aforementioned embodiment, it is beneficial to reduce the size of the mounting cavity, and thus to reduce the overall external outline size of the atomizer 80, making the structure of the atomizer 80 more compact.

[0142] In some embodiments, see Figures 10 to 14 The mounting assembly 20 also includes an airflow channel 20b, which is connected to the mounting cavity along with the liquid storage chamber 20a. The atomizing core 10 isolates the airflow channel 20b from the liquid storage chamber 20a. The first liquid guiding area 111 and the second liquid guiding area 112 are both in fluid communication with the airflow channel 20b.

[0143] The atomizing core 10 can act as a seal to reduce the probability that the aerosol generation matrix in the liquid storage chamber 20a will directly enter the airflow channel 20b through the gap between the atomizing core 10 and the inner wall of the mounting chamber and then leak out of the atomizer 80.

[0144] Both ends of the airflow channel 20b are connected to the outside of the atomizer 80. During the use of the atomizer 80, one end of the airflow channel 20b is connected to the user's oral cavity, so that a negative pressure is generated inside the airflow channel 20b. Under the action of negative pressure, outside air enters the airflow channel 20b through the other end of the airflow channel 20b, and the atomized aerosol generating matrix formed by the liquid 11 also enters the airflow channel 20b. The atomized aerosol generating matrix mixes with the airflow to form an aerosol, which enters the user's oral cavity through the airflow channel 20b.

[0145] In some embodiments, see Figures 10 to 14 The atomizer 80 also includes a first electrode 40 and a second electrode 50. Both the first electrode 40 and the second electrode 50 are installed in the mounting assembly 20. The first electrode 40 is electrically connected to the first electrode part 131, and the second electrode 50 is electrically connected to the second electrode part 133.

[0146] The first electrode 40 and the second electrode 50 are respectively used for electrical connection with an external power supply assembly.

[0147] In some implementations, see reference. Figures 10 to 14 The mounting assembly 20 includes a housing 31 and a mounting base 30. The housing 31 is provided with a liquid storage space and a first airflow sub-channel 31a. One side of the liquid storage space is open. The mounting base 30 is sealed at the open position of the liquid storage space. The mounting base 30 is provided with a mounting cavity, a second airflow sub-channel and multiple liquid guiding channels. Each liquid guiding channel is connected to each liquid storage space to form a liquid storage cavity 20a. The first airflow sub-channel 31a and the second airflow sub-channel are connected to each other to form an airflow channel 20b.

[0148] In some embodiments, see Figure 11 , Figure 12 , Figure 13 and Figure 14 The housing 31 includes a casing 311, an air guide column 312, and multiple partition ribs 313. The casing 311 has an installation space with one side open. The air guide column 312 is located in the installation space. A first air flow sub-channel 31a is located in the air guide column 312. The partition ribs 313 connect the air guide column 312 to the inner wall of the installation space to divide the installation space into multiple liquid storage spaces.

[0149] In some embodiments, the first airflow sub-channel 31a extends through the housing 31 along the first direction, and the liquid storage space is open on one side along the first direction, so that the housing 31 is formed by demolding along the first direction after injection molding. This simplifies the manufacturing process of the housing 31 and makes the housing 31 a one-piece structure, which helps to reduce the number of parts of the atomizer 80.

[0150] In some embodiments, see Figure 10 and Figure 11 The airflow channel 20b is connected to the outside to form an air outlet 20c. The contact area between the first heating element 134 and the first liquid guiding area 111, as well as the contact area between the second heating element 135 and the second liquid guiding area 112, are all located on the inner wall of the airflow channel 20b and face the air outlet 20c.

[0151] In this way, the aerosol generated by the atomized aerosol matrix can flow directly out of the atomizer 80 through the outlet 20c in the first direction, which helps to reduce the resistance encountered by the aerosol in the process of flowing out of the atomizer 80.

[0152] It is understood that in these embodiments, the surface of the liquid guide 11 that is in contact with the aerosol generating matrix is ​​located on the side of the atomizing core 10 opposite to the air outlet 20c, and a portion of the liquid storage chamber 20a is located on the side of the atomizing core 10 opposite to the air outlet 20c so as to be in fluid communication with the liquid absorption surface 11a.

[0153] In other embodiments, see Figures 12 to 14 The airflow channel 20b is connected to the outside to form an air outlet 20c. The contact area between the first heating element 134 and the first liquid guiding area 111, as well as the contact area between the second heating element 135 and the second liquid guiding area 112, are all located on the inner wall of the airflow channel 20b and away from the air outlet 20c.

[0154] This allows the aerosol generating matrix in the liquid storage chamber 20a to come into contact with the liquid guide 11 more quickly under the influence of gravity, reducing the probability of problems such as dry burning of the heating element 132 due to untimely supply of the aerosol generating matrix, and improving the user experience.

[0155] In some embodiments, during the user's inhalation of the aerosol, the first direction is generally along the direction of gravity, and the outlet 20c is located at one end of the aerosol generating device along the first direction.

[0156] It is understood that in these embodiments, the contact areas of the first heating element 134 and the first liquid guiding area 111, as well as the contact areas of the second heating element 135 and the second liquid guiding area 112, are all located on the side of the atomizing core 10 away from the air outlet 20c. A portion of the airflow channel 20b is routed around the side of the mounting cavity perpendicular to the first direction, such that a portion of the airflow channel 20b is located on the side of the atomizing core 10 away from the air outlet 20c and another portion is located on the side of the atomizing core 10 close to the air outlet 20c, so as to achieve fluid communication between the contact areas of the first heating element 134 and the first liquid guiding area 111, and the contact areas of the second heating element 135 and the second liquid guiding area 112, respectively, and the first airflow sub-channel 31a.

[0157] This application also provides an aerosol generating device, see below. Figures 12 to 14 The aerosol generating device includes a first power supply assembly 60 and any of the atomizing cores 10 in the aforementioned embodiments. One of the first electrode portion 131 and the second electrode portion 133 can be electrically connected to the positive electrode of the first power supply assembly 60, and the other can be electrically connected to the negative electrode of the first power supply assembly 60.

[0158] The first power supply component 60 can supply power to the atomizing core 10 through the positive and negative terminals, thereby converting electrical energy into heat energy, and thus achieving the purpose of generating a matrix from atomized aerosol.

[0159] Thus, by adopting the atomizing core 10 in the aforementioned embodiments, it is beneficial to make the overall structure of the aerosol generating device more compact, to reduce the outer contour size of the aerosol generating device, to improve the portability of the aerosol generating device, and to improve the user experience.

[0160] In some embodiments, the first electrode portion 131 and the second electrode portion 133 are in direct contact with the positive and negative terminals of the first power supply assembly 60, respectively, to achieve electrical connection.

[0161] In some embodiments where a first electrode 40 and a second electrode 50 are provided, see [reference]. Figure 11 One end of the first electrode 40 and the second electrode 50 respectively contacts the first electrode portion 131 and the second electrode portion 133, and the other end respectively contacts the positive and negative terminals of the first power supply assembly 60 to achieve electrical connection.

[0162] In some embodiments, the first power supply assembly 60 includes a battery, a positive terminal, and a negative terminal. The positive terminal is electrically connected to the positive terminal of the battery, and the negative terminal is electrically connected to the negative terminal of the battery. The positive terminal forms the positive terminal of the first power supply assembly 60, and the negative terminal forms the negative terminal of the first power supply assembly 60.

[0163] The specific type of battery is not limited, such as lithium batteries.

[0164] In some embodiments, the aerosol generating device includes the atomizer 80 from the foregoing embodiments.

[0165] This application also provides an aerosol generating device, see below. Figures 15 to 19 The aerosol generating device includes a second power supply assembly 61, which includes a battery, a first electrical connector 611, and at least two second electrical connectors 612.

[0166] In some embodiments, see Figure 16 and Figure 17 The aerosol generating device also includes any of the atomizers 80 in the foregoing embodiments, the second electrical connector 612 is electrically connected to one of the positive and negative electrodes of the battery and one of the second electrode portions 133 through the conductive region, and the first electrical connector 611 is electrically connected to the other of the positive and negative electrodes of the battery and the first electrode portion 131.

[0167] In other embodiments, see Figure 18 and Figure 19 The aerosol generating device also includes a second atomizer 70, which includes a second atomizing core 71 and two third electrode components 72. The third electrode components 72 are electrically connected to the second atomizing core 71. A portion of the second electrical connector 612 is electrically connected to one of the third electrode components 72 and one of the positive and negative terminals of the battery through a conductive area. The conductive area of ​​another portion of the second electrical connector 612 is electrically connected to the other third electrode component 72 and the other of the positive and negative terminals of the battery.

[0168] In other words, the second power supply component 61 in this embodiment can be adapted to the atomizer 80 in the aforementioned embodiment, and can also be adapted to the second atomizer 70.

[0169] When adapted to atomizer 80, all second electrical connectors 612 have the same electrode polarity, which is opposite to that of the first connector. When adapted to second atomizer 70, some second electrical connectors 612 have electrode polarities opposite to those of others, and the first electrical connector 611 is not electrically connected to the battery. Depending on whether the atomizer 80 or second atomizer 70 is adapted, the positive or negative terminal of the battery can selectively cause the second power assembly 61 to be in a first operating state where both the first and second electrical connectors 611 and 612 are electrically connected to the battery and have opposite electrode polarities, or in a second operating state where the first electrical connector 611 is disconnected and the multiple second electrical connectors 612 are divided into two parts with different electrode polarities.

[0170] This allows the second power supply component 61 to be compatible with the atomizer 80 and the second atomizer 70, which helps to improve the applicability of the second power supply component 61 and reduce the user's operating costs.

[0171] It is understandable that the structure of the second atomizing core 71 of the second atomizer 70 is different from the structure of the atomizing core 10 in the aforementioned embodiment.

[0172] The specific method by which the control of the second power supply assembly 61 switches between the first operating state and the second operating state is not limited. For example, the second power supply assembly 61 includes a control device that can acquire the resistance value of the atomizer 80 or the second atomizer 70, and selectively control the electrical connection state of the first electrical connector 611 and the second electrical connector 612 according to the different resistance values, so that the second power supply assembly 61 is in the first operating state or in the second operating state.

[0173] In some embodiments, see Figure 17 and Figure 19 The outer surface of the second electrical connector 612 is provided with at least two electrical connection protrusions 6121, and the electrical connection protrusions 6121 are spaced apart from each other, forming a conductive area of ​​the second electrical connector 612.

[0174] In other words, the second electrical connector 612 is electrically connected to one of the first electrode 40 and the second electrode 50, or to the third electrode 72, through at least one electrical connection protrusion 6121.

[0175] By setting multiple electrical connection protrusions 6121, it is beneficial to enable the second power supply assembly 61 to be adapted to atomizers 80 and 70 of different sizes, thereby improving the applicability of the second power supply assembly 61. The multiple electrical connection protrusions 6121 on the same second electrical connector 612 are spaced apart from each other, which helps to reduce the contact area between the second electrical connector 612 and the atomizers 80 and 70 respectively. This helps the second electrical connector 612 maintain electrical conductivity with the atomizers 80 and 70, and reduces the probability of unstable electrical conductivity of the second electrical connector 612 due to manufacturing and assembly errors.

[0176] In some embodiments, see Figure 17 and Figure 19 The electrical connection protrusion 6121 is located on one side of the second electrical connector 612 along the first direction so as to be adapted to the atomizer 80 and the second atomizer 70 along the first direction for easy installation.

[0177] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0178] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
