[0030] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0031] It should be understood that the directional terms in the embodiments of the present application are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] See also Figures 1 to 7On the one hand, an embodiment of the present application provides an atomization assembly 10, which includes an atomization seat 11 and an atomization core 12. Among them, the atomization seat 11 has an atomization chamber 11a and at least one liquid inlet channel 11b. The atomization core 12 is arranged in the atomization chamber 11a of the atomization seat 11, and the atomization core 12 includes a heating element 121 and a substrate 122. The substrate 122 has a first end and a second end that are relatively arranged, and the substrate 122 includes a first liquid supply surface 122a arranged at the first end, an atomization surface 122c arranged at the second end, and at least one second liquid supply surface 122b arranged on the outer peripheral surface between the first end and the second end. The liquid inlet channel 11b of the atomization seat 11 is liquid-connected with the first liquid supply surface 122a and the second liquid supply surface 122b. The heating element 121 is arranged on the atomization surface 122c, and is used to atomize the aerosol generating matrix to generate an aerosol.

[0033] The substrate 122 includes a first liquid supply surface 122a arranged at the first end, an atomization surface 122c arranged at the second end, and at least one second liquid supply surface 122b arranged on the outer peripheral surface between the first end and the second end, which means that the substrate 122 has a first liquid supply surface 122a and at least one second liquid supply surface 122b.

[0034] The first liquid supply surface 122a and the atomization surface 122c are arranged opposite to each other on the base 122, and the second liquid supply surface 122b is arranged on the outer peripheral surface between the first end and the second end. In other words, the second liquid supply surface 122b is arranged on at least one outer peripheral surface between the first end and the second end.

[0035] Exemplarily, the number of the second liquid supply surfaces 122b may be 1, 2, 3 or 4, etc.

[0036] It should be noted that the specific contour shape of the base 122 is not limited here, and the contour shape of the base 122 includes but is not limited to a polyhedron, a prism, a prism, a frustum or a cylinder.

[0037] It can be understood that if the aerosol generating matrix infiltrates the substrate 122 and there is a microporous channel on the substrate 122, the microporous channel will penetrate the aerosol generating matrix into the interior of the substrate 122 through capillary action, so that the aerosol generating matrix penetrates into the substrate 122 from the first liquid supply surface 122a and the second liquid supply surface 122b, and reaches the atomization surface 122c through the microporous channel.

[0038] The microporous channel can conduct liquid and temporarily store liquid through capillary action so that the aerosol-generating matrix can be continuously replenished to the atomization surface 122c.

[0039] It should be noted that wetting refers to the phenomenon that when a liquid comes into contact with a solid, the liquid adheres to the surface of the solid or penetrates into the interior of the solid. At this time, for the solid, the liquid is called the wetting liquid.

[0040] It should be noted that the material of the substrate 122 is not limited here. For example, in one embodiment, the substrate 122 is a conductive material, such as a metal or alloy such as iron-chromium-aluminum, nickel-chromium or stainless steel. In other embodiments, the substrate 122 may also be an electrical insulating material, including but not limited to ceramics, glass, polyimide, etc. The following embodiments are all illustrated by taking the substrate 122 as ceramic as an example.

[0041] The structure of the heating element 121 can be a continuous film, a porous mesh, a sheet or a strip. The material, shape and size of the heating element 121 can be set as required.

[0042] In one embodiment, the specific structural form of the heating element 121 is a heating film disposed on the atomizing surface 122c.

[0043] It should be noted that the base 122 has a first end and a second end which are arranged opposite to each other. The first end and the second end can be as follows: Figure 3 The marked positions are relatively arranged, that is, the first end is at the top of the base 122, and the second end is at the bottom of the base 122. The first end and the second end can also be at other parts of the base 122, respectively, which is not limited here.

[0044] The liquid inlet channel 11b of the atomizer seat 11 is liquid-connected with the first liquid supply surface 122a and the second liquid supply surface 122b, which means that the aerosol generating matrix can be guided to the first liquid supply surface 122a and the second liquid supply surface 122b on the substrate 122 through the liquid inlet channel 11b. The first liquid supply surface 122a and the second liquid supply surface 122b are used to absorb the aerosol generating matrix. After the aerosol generating matrix is ​​absorbed by the first liquid supply surface 122a and the second liquid supply surface 122b on the substrate 122, it is guided to the atomization surface 122c through the inside of the substrate 122.

[0045] In one embodiment, the substrate 122 is Figure 6 and Figure 7 The first liquid supply surface 122 a is located at the top of the base 122 , and there are two second liquid supply surfaces 122 b , which are located on the left and right sides of the base 122 , respectively. Figure 6 a is 9mm, b is 2.2mm, Figure 7 c is 2.2 mm, d is 1.73 mm. Therefore, it can be concluded that the area of ​​the first liquid supply surface 122a is 9 mm×2.2 mm=19.8 mm 2 The total area of ​​the second liquid supply surface 122b is 2×2.2mm×1.73mm=7.612mm 2 Compared with supplying liquid only through the first liquid supply surface 122a, the total liquid supply area of ​​the substrate 122 is increased.

[0046] In another specific embodiment, the first liquid supply surface 122a is located at the top of the base 122, and the number of second liquid supply surfaces 122b is two, which are located at the front and rear sides of the base 122 respectively. Figure 6 a is 9 mm, b is 2.2 mm, and Figure 7 c in the figure can be the same as a, which is 9 mm, and d can be 1.73 mm. At this time, the area of ​​the second liquid supply surface 122b is further increased, further increasing the total liquid supply area of ​​the substrate 122.

[0047] In the atomizer assembly 10 of the embodiment of the present application, the base 122 is provided with a first liquid supply surface 122a at the first end, and at least one second liquid supply surface 122b is provided on the outer peripheral surface between the first end and the second end, so that the total area of ​​the liquid supply surface of the atomizer core 12 is increased, thereby improving the liquid supply amount of the base 122. At the same time, compared with the liquid supply distance from the first liquid supply surface 122a to the atomizing surface 122c opposite thereto, the liquid supply distance from the second liquid supply surface 122b to the atomizing surface 122c is shorter, thereby shortening the liquid supply path and liquid supply time of at least part of the aerosol generating matrix, increasing the liquid supply speed, and thus improving the liquid supply efficiency of the atomizer assembly 10. To a certain extent, it can improve the situation where the burnt / burnt smell occurs due to insufficient liquid supply when the atomization frequency is fast, or the liquid supply does not meet the demand for products with large atomization power, thereby improving the user experience.

[0048] For some examples, see Figures 3 to 7 The liquid inlet channel 11b includes a liquid inlet 11c, a first liquid outlet 11d and a second liquid outlet 11e. The first liquid outlet 11d and the second liquid outlet 11e are both connected to the liquid inlet 11c. The first liquid outlet 11d is in liquid communication with the first liquid supply surface 122a, and the second liquid outlet 11e is in liquid communication with the second liquid supply surface 122b.

[0049] It is understandable that the liquid inlet 11 c may be disposed on the top wall of the atomizer seat 11 , or may be disposed at other positions of the atomizer seat 11 .

[0050] It should be noted that the first liquid outlet 11d is in liquid communication with the first liquid supply surface 122a, and the second liquid outlet 11e is in liquid communication with the second liquid supply surface 122b, which means that the aerosol generating matrix can enter the liquid inlet channel 11b from the liquid inlet 11c of the atomizer seat 11, and part of the aerosol generating matrix is ​​guided to the first liquid supply surface 122a on the substrate 122 in the liquid inlet channel 11b, thereby being absorbed into the substrate 122 by the first liquid supply surface 122a; another part of the aerosol generating matrix is ​​guided to the second liquid supply surface 122b on the substrate 122 in the liquid inlet channel 11b, thereby being absorbed into the substrate 122 by the second liquid supply surface 122b.

[0051] Thus, the first liquid outlet 11d and the second liquid outlet 11e of the liquid inlet channel 11b are respectively connected to the first liquid supply surface 122a and the second liquid supply surface 122b, so that the aerosol generating matrix is ​​diverted in the liquid inlet channel 11b and enters the matrix 122 from the first liquid supply surface 122a and the second liquid supply surface 122b, respectively, thereby increasing the liquid supply area of ​​the matrix 122 and thus increasing the liquid supply amount of the matrix 122.

[0052] For some examples, see Figure 3 to Figure 4 , along the direction from the first end to the second end, the minimum distance between the second liquid outlet 11e and the atomization surface 122c is 0.5mm-1mm, for example, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm.

[0053] The minimum distance between the second liquid outlet 11e and the atomizing surface 122c is, for example, the distance between the lowest point of the second liquid outlet 11e and the atomizing surface 122c, that is, the distance between the lowest point of the second liquid outlet 11e and the atomizing surface 122c is 0.5mm-1mm.

[0054] It can be understood that the smaller the minimum distance between the second liquid outlet 11e and the atomization surface 122c is, the shorter the liquid supply distance of the aerosol generating substrate is.

[0055] The minimum distance between the second liquid outlet 11e and the atomizing surface 122c along the direction from the first end to the second end is Figure 4 f in the figure can be 0.5mm-1mm, so that the position of the second liquid outlet 11e is closer to the atomizing surface 122c than the position of the first liquid outlet 11d, thereby making the liquid supply distance from the second liquid outlet 11e, that is, from the second liquid supply surface 122b into the substrate 122 to reach the atomizing surface 122c shorter. In the same time, the amount of liquid supplied from the second liquid supply surface 122b to the atomizing surface 122c is greater.

[0056] For some examples, see Figures 3 to 7 The number of the second liquid supply surfaces 122b is two, and the two second liquid supply surfaces 122b are arranged opposite to each other.

[0057] When there are two second liquid supply surfaces 122b, two liquid inlet channels 11b may be provided, and the second liquid outlets 11e of the two liquid inlet channels 11b correspond to the two second liquid supply surfaces 122b respectively.

[0058] Of course, one liquid inlet channel 11b may be provided, and two second liquid outlets 11e of the liquid inlet channel 11b may be provided correspondingly, and the two second liquid outlets 11e correspond to the two second liquid supply surfaces 122b respectively.

[0059] In a specific embodiment, the atomizer seat is provided with two liquid inlet channels 11b, and the two second liquid supply surfaces 122b are arranged opposite to each other. The two liquid inlet channels 11b can be correspondingly designed symmetrically, so that the design of the atomizer assembly 10 is simpler and the installation is more convenient. At the same time, the two second liquid supply surfaces 122b arranged opposite to each other make the second liquid supply surface 122b supply liquid to the atomizing surface 122c more evenly distributed at both ends, which is conducive to uniform liquid supply.

[0060] Exemplarily, the number of the second liquid supply surfaces 122b can also be three, wherein two second liquid supply surfaces 122b are arranged opposite to each other, and the number of second liquid outlets 11e of the liquid inlet channel 11b is correspondingly set to three, and one second liquid outlet 11e corresponds to one second liquid supply surface 122b.

[0061] Similarly, the number of the second liquid supply surfaces 122b can also be four, and the four second liquid supply surfaces 122b are arranged opposite to each other in pairs, and the number of second liquid outlets 11e of the liquid inlet channel 11b is correspondingly set to four, and one second liquid outlet 11e corresponds to one second liquid supply surface 122b.

[0062] The number of the second liquid supply surfaces 122b can also be 5, 6, 7 or 8, etc., which is not limited here.

[0063] In some embodiments, see Figures 3 to 7 , the base body 122 is in a rectangular parallelepiped shape.

[0064] In a specific embodiment, at least one side surface of the cuboid is provided with a second liquid supply surface 122b.

[0065] It should be noted that the cross-sectional shape of the cuboid can be a square (in which case the cuboid is a cube) or a rectangle.

[0066] It should be noted that, when the base body 122 is in a rectangular parallelepiped shape, the number of the second liquid supply surfaces 122 b may be 1, 2, 3 or 4.

[0067] If the top surface of the cuboid is set as the first liquid supply surface 122a, the bottom surface of the cuboid is the atomization surface 122c, and the four side surfaces are the second liquid supply surfaces 122b. It should be noted that the top surface of the cuboid here is only a relative position and is not limited to a certain surface of the cuboid.

[0068] Therefore, by setting the base 122 as a rectangular parallelepiped, the structure of the base 122 is simple, which is convenient for design and product installation.

[0069] For some examples, see Figures 3 to 7 , the direction from the first end to the second end is the height direction of the atomization assembly 10.

[0070] When the direction from the first end to the second end is the height direction of the atomizer assembly 10, illustratively, the first liquid supply surface 122a is located on the top surface of the base 122, the atomization surface 122c is located on the bottom surface of the base 122, and the second liquid supply surface 122b is located around the side.

[0071] In some embodiments, the direction from the first end to the second end is perpendicular to the height direction of the atomizer assembly 10 .

[0072] When the direction from the first end to the second end is perpendicular to the height direction of the atomization assembly 10, if the first liquid supply surface 122a is located on the front side of the base 122, the atomization surface 122c is located on the rear side of the base 122, and the second liquid supply surface 122b is located on the top surface, bottom surface, left side surface or right side surface of the base 122.

[0073] For some examples, see Figures 3 to 7 The atomizer core 12 further includes a seal 123 that is sealed and clamped between the base 122 and the atomizer seat 11. The seal 123 is provided with a first avoidance hole 123b (not shown) and a second avoidance hole 123c (not shown). The liquid inlet channel 11b is liquid-connected to the first liquid supply surface 122a and the second liquid supply surface 122b through the first avoidance hole 123b and the second avoidance hole 123c, respectively.

[0074] It should be noted that the sealing member 123 is sealingly sandwiched between the base 122 and the atomizer seat 11 to seal the liquid inlet channel 11 b, thereby avoiding leakage of the aerosol generating matrix to a certain extent.

[0075] The sealing member 123 is provided with a first avoidance hole 123b for avoiding the first liquid supply surface 122a and a second avoidance hole 123c for avoiding the second liquid supply surface 122b, and the liquid supply surface and the avoidance hole may correspond one to one. For example, a first avoidance hole 123b avoids a first liquid supply surface 122a, and a second avoidance hole 123c avoids a second liquid supply surface 122b. It is understandable that the liquid supply surface and the avoidance hole may also be one-to-many, many-to-one or many-to-many. Here, "many" refers to two or more situations, which will not be repeated here.

[0076] In a specific embodiment, the sealing member 123 may be made of silicone.

[0077] Therefore, the sealing member 123 is sandwiched between the base 122 and the atomizer seat 11, and the first avoidance hole 123b and the second avoidance hole 123c are set on the sealing member 123, so that the base 122 can be protected in the atomizer seat 11, and the sealing member 123 can form a sealing structure with the atomizer seat 11 and the liquid inlet channel 11b, thereby avoiding leakage of the aerosol generating matrix to a certain extent.

[0078] For some examples, see Figures 3 to 7 The first avoidance hole 123 b and the second avoidance hole 123 c penetrate the surface of the sealing member 123 .

[0079] The first avoidance hole 123b and the second avoidance hole 123c penetrate the surface of the sealing member 123, which means that the first avoidance hole 123b and the second avoidance hole 123c can be communicating holes, and the first avoidance hole 123b and the second avoidance hole 123c are connected after penetrating the physical structure of the sealing member 123.

[0080] The first avoidance hole 123b and the second avoidance hole 123c are connected on the surface of the sealing member 123, so that the area of ​​the first liquid supply surface 122a and the second liquid supply surface 122b is further increased, thereby increasing the liquid supply amount of the base 122. At the same time, the aerosol generating substrate at the first liquid supply surface 122a and the second liquid supply surface 122b can flow to each other through the first avoidance hole 123b and the second avoidance hole 123c on the surface of the sealing member 123. If one of the first liquid supply surface 122a and the second liquid supply surface 122b is supplied with too much liquid, the excess aerosol generating substrate can flow to the other liquid supply surface, thereby optimizing the problem of uneven liquid supply when the liquid supply is too much to a certain extent.

[0081] In some other embodiments, the first avoidance hole 123 b and the second avoidance hole 123 c do not penetrate the surface of the sealing member 123 , that is, there is a partition wall between the first avoidance hole 123 b and the second avoidance hole 123 c , thereby improving the structural strength of the sealing member 123 .

[0082] For some examples, see Figures 1 to 7 The atomizer seat 11 includes an atomizer upper seat 111 and an atomizer lower seat 112, the atomizer upper seat 111 and the atomizer lower seat 112 define an atomizer chamber 11a, the atomizer upper seat 111 has a liquid inlet channel 11b, and at least part of the area around the sealing member 123 is provided with a flange 123a, and the flange 123a is sealed and clamped between the atomizer upper seat 111 and the atomizer lower seat 112.

[0083] The atomizer seat 11 is provided with an atomizer upper seat 111 and an atomizer lower seat 112 , which is beneficial to the installation of the atomizer core 12 .

[0084] The fact that the flange 123 a is provided on at least a portion of the circumference of the seal 123 means that the flange 123 a may be provided on the entire circumference of the seal 123 or may be provided on a portion of the circumference of the seal 123 .

[0085] The flange 123a is sealingly clamped between the atomizing upper seat 111 and the atomizing lower seat 112, so that the sealing between the atomizing upper seat 111 and the atomizing lower seat 112 is better, thereby reducing the leakage of aerosol.

[0086] Another aspect of the present application provides an atomizer. Figure 8 The atomizer includes a housing 50 and an atomizer assembly 10 provided in any embodiment of the present application. The housing 50 has a cavity 50b and an air outlet channel 50a. The atomizer seat 11 of the atomizer assembly 10 is disposed in the cavity 50b and defines a liquid storage space 100a with the side wall of the cavity 50b. The liquid storage space 100a is in liquid communication with the liquid inlet channel 11b.

[0087] The housing 50 has an air outlet passage 50a, which is connected to the atomization chamber 11a and is used to discharge the generated aerosol for use by the user.

[0088] It should be noted that the liquid storage space 100a is used to store the aerosol generating substrate to be used.

[0089] The liquid storage space 100a is in liquid communication with the liquid inlet channel 11b, which means that the aerosol generating matrix in the liquid storage space 100a can be guided to the atomizing core 12 through the liquid inlet channel 11b, so that the aerosol generating matrix can reach the atomizing surface 122c of the atomizing core 12, be atomized by heat, and generate aerosol.

[0090] Therefore, by combining the atomizer assembly 10 with the shell 50 of the atomizer, the aerosol generating matrix can be continuously provided to the atomizer assembly 10, and the aerosol generated by the aerosol generating matrix can also be continuously output from the air outlet channel 50a for use. The atomizer assembly 10 with higher liquid supply efficiency improves the user experience of the atomizer.

[0091] Another aspect of the present invention provides an aerosol generating device 200. Figure 8 The aerosol generating device 200 includes a power supply assembly 210 and an atomizing assembly 10 provided in any embodiment of the present application.
