When supplied with energy, the atomizing element heats and atomizes an aerosol-generating matrix, producing an aerosol for the user to inhale. Current aerosol generators often use downward-facing atomizing surfaces or traditional cotton-wick-shaped atomization methods.

[0033] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of the present disclosure can be combined with each other, and the detailed description in the specific implementation methods should be understood as an explanation of the purpose of the present disclosure and should not be regarded as an improper limitation on the present disclosure.

[0034] In the description of the embodiments of the present disclosure, it should be noted that the terms "upper," "lower," "top," and "bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in Figures 2 to 4. These orientation terms are intended solely to facilitate the description of the embodiments of the present disclosure and to simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the embodiments of the present disclosure. The present disclosure will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] One aspect of an embodiment of the present disclosure provides an aerosol generating device, as shown in Figures 1 to 4 , comprising a power supply assembly and an atomizer 100 provided in any embodiment of the present disclosure. The power supply assembly is electrically connected to a conductive member of the atomizer 100. In this embodiment, the atomizer 100 exists independently of the power supply assembly, and the atomizer 100 and the power supply assembly are detachably connected. However, in some embodiments, the power supply assembly and the atomizer 100 are enclosed in the same housing and are relatively non-detachable.

[0036] The power supply device is primarily used to power the aerosol generator 100 and control operations such as turning the aerosol generator on and off. The aerosol generator 100 is primarily used to house an aerosol-generating substrate and, when powered on, heat and atomize the substrate. The aerosol-generating substrate includes, but is not limited to, materials used for medical, health, wellness, and cosmetic purposes.

[0037] In some embodiments, the atomizer 100 and the power supply unit can be mechanically and electrically connected axially. Furthermore, the atomizer 100 and the power supply unit can be connected together via a detachable connection, such as a magnetic connection, a threaded connection, or a snap-on connection. Both the atomizer 100 and the power supply unit can be replaced or upgraded independently, reducing replacement costs and saving users money. Of course, in other embodiments, the atomizer 100 and the power supply unit can also be connected together in a non-detachable manner.

[0038] Furthermore, the atomizer 100 and / or the power supply device are not limited to being cylindrical, and may also be in other shapes such as an elliptical cylinder, a square box, or a polygonal cylinder. For example, in this embodiment, the cross-section of the lower end of the atomizer 100 is approximately rectangular, while the cross-section of the upper portion of the atomizer is closer to an ellipse.

[0039] It should be noted that the specific type of the aerosol generating device provided in the embodiments of the present disclosure is not limited. For example, the aerosol generating device can be a medical atomization device, an air humidifier, or an atomization device such as an electronic cigarette.

[0040] In some embodiments, the aerosol generating device of the present disclosure, as shown in Figures 1 to 4, includes a power supply assembly and an atomizer core 10 provided in any embodiment of the present disclosure. The electrode column of the power supply assembly is electrically connected to the electrode 15.

[0041] Another aspect of the present disclosure provides an atomizer 100, comprising a conductive member and an atomizer core 10 provided in any embodiment of the present disclosure. In this embodiment, the conductive member comprises a first conductive member 30 and a second conductive member 40; accordingly, the atomizer core 10 has electrodes 15, comprising a first electrode 13 and a second electrode 14. The first conductive member 30 is electrically connected to the first electrode 13 of the atomizer core 10, and the second conductive member 40 is electrically connected to the second electrode 14 of the atomizer core 10. The atomizer 100 is electrically connected to a power supply assembly via the first conductive member 30 and the second conductive member 40. Specifically, the atomizer 100 is electrically connected to the atomizer core 10 by providing the first conductive member 30 and the second conductive member 40, and the power supply assembly is electrically connected to the atomizer core 10 via the first conductive member 30 and the second conductive member 40, so that the power supply assembly can power the atomizer core 10 of the atomizer 100 and control operations such as turning the entire aerosol generating device on or off. When powered on, the atomizer core 10 can heat the atomized aerosol generating substrate to form an aerosol.

[0042] In the related art, the atomizing core of the aerosol generating device is generally a cotton core heating element or a ceramic core. However, the current ceramic core atomizer, especially the small volume (about 2ml) products, is generally limited by the volume space and adopts the method of downward atomization (that is, the atomizing surface faces the bottom of the atomizer). In the above two mainstream methods, the aerosol generated by atomization needs to be bent before finally reaching the user, so the aerosol loss is large, which makes it difficult to improve the atomization efficiency and taste. The present disclosure adopts the method of lateral atomization (that is, the atomizing surface faces the side), which can reduce the loss of aerosol, but the electrical connection of the atomizing core has the problem of complex connection structure, and may damage the atomizing surface.

[0043] The atomizer core 10 provided in the embodiment of the present disclosure, please refer to Figures 2 to 7, includes a substrate 11, a heating element 12 and an electrode. The outer peripheral surface of the substrate 11 includes at least one atomizing surface 11c and a non-atomizing surface 11a. A heating element 12 is provided on at least one atomizing surface 11c, and the heating element 12 is used to heat the atomized aerosol to generate a matrix. The electrode 15 includes a connecting area 15a and a turning area 15b. The connecting area 15a is provided on the non-atomizing surface 11a, and the turning area 15b extends from the connecting area 15a and turns to the atomizing surface 11c, and is electrically connected to the heating element 12.

[0044] The outer peripheral surface of the base body 11 includes at least one atomized surface 11 c and a non-atomized surface 11 a . That is, the atomized surface 11 c and the non-atomized surface 11 a are respectively provided on different outer peripheral surfaces of the base body 11 .

[0045] Exemplarily, the electrode 15 includes a first electrode 13 and a second electrode 14 .

[0046] The connection region 15a is provided on the non-atomized surface 11a, and the turning region 15b extends from the connection region 15a and turns to the atomized surface 11c. The turning region 15b is used to realize the turning of the electrode 15 from the non-atomized surface 11a to the atomized surface 11c, so as to achieve electrical connection between the connection region 15a and the heating element 12 on the atomized surface 11c. The conductive element contacts the connection region 15a on the non-atomized surface 11a to achieve electrical connection, thereby preventing the conductive element from damaging the atomized surface 11c and the heating element 12.

[0047] That the outer peripheral surface of the substrate 11 includes at least one atomized surface 11 c means that the substrate 11 may include one atomized surface 11 c (as shown in FIG. 4 and FIG. 6 ) or a plurality of atomized surfaces 11 c (as shown in FIG. 3 and FIG. 7 ).

[0048] The multiple mentioned in the embodiments of the present disclosure refers to a number of two or more.

[0049] In some embodiments, the atomized surface 11 c is disposed on a side surface of the substrate 11 , and the connection region 15 a of the electrode 15 is disposed on a bottom surface of the substrate 11 .

[0050] Taking the substrate 11 as a rectangular parallelepiped as an example, the atomized surface 11c is arranged on the side of the rectangular parallelepiped, and the connection areas 15a of the first electrode 13 and the second electrode 14 are both arranged on the bottom surface of the substrate 11, for respectively connecting with the first conductive member 30 and the second conductive member 40. In this way, the contact between the atomized surface 11c and the first conductive member 30 can be turned through the turning area 15b of the first electrode 13, and the contact between the atomized surface 11c and the second conductive member 40 can be turned through the turning area 15b of the second electrode 14, that is, the turning area 15b realizes the turning of the electrode 15 from the non-atomized surface 11a to the atomized surface 11c, so as to realize the contact between the connection area 15a and the heating element 12 on the atomized surface 11c.

[0051] Taking the substrate 11 as a cylinder as an example, the atomized surface 11c is arranged on the circumferential side surface of the cylinder, and at least part of the first electrode 13 and the second electrode 14 are arranged on the bottom surface of the cylinder, which are used to abut and connect with the first conductive member 30 and the second conductive member 40 respectively. In this way, the contact between the atomized surface 11c and the first conductive member 30 can be turned through the turning area 15b of the first electrode 13, and the contact between the atomized surface 11c and the second conductive member 40 can be turned through the turning area 15b of the second electrode 14.

[0052] It should be noted that the material of the substrate 11 is not limited herein. For example, in one embodiment, the substrate 11 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 11 may also be an electrically insulating material, including but not limited to ceramic, glass, polyimide, etc. The following embodiments are illustrated using the substrate 11 as a ceramic material.

[0053] It should be noted that there are many ways to form the first electrode 13 and the second electrode 14. For example, when the material of the substrate 11 is an electrically insulating material, the first electrode 13 and the second electrode 14 can be a conductive coating applied to the substrate 11. The conductive coating can be a metal coating, a conductive silver paste or a conductive tape, etc., or it can be a metal conductive sheet provided at the end of the substrate 11 or a metal deposited at the end of the substrate 11, such as a gold film, an aluminum film or a copper film.

[0054] In the embodiment of the present disclosure, the first electrode 13 and the second electrode 14 are formed on the substrate 11 by drilling and grouting.

[0055] The atomizer core 10 provided in the embodiment of the present disclosure includes a base 11, a heating element 12, and an electrode 15. The outer peripheral surface of the base 11 includes an atomizing surface 11c and a non-atomizing surface 11a. The heating element 12 is provided on at least one atomizing surface 11c. The electrode 15 includes a connection area 15a and a turning area 15b. The connection area 15a is provided on the non-atomizing surface 11a. The turning area 15b extends from the connection area 15a and turns to the atomizing surface 11c, and is electrically connected to the heating element 12. In other words, the turning area 15b is used to realize the turning of the electrode 15 from the non-atomizing surface 11a to the atomizing surface 11c, with the purpose of realizing the electrical connection between the connection area 15a and the heating element 12 on the atomizing surface 11c. In this way, the connection structure between the atomizer core 10 and the power supply assembly is simplified, and the conductive element is electrically connected to the electrode 15 on the connection area 15a of the non-atomizing surface 11a, thereby preventing the conductive element from damaging the atomizing surface 11c and the heating element 12.

[0056] It should be noted that the specific outline shape of the base 11 is not limited here, and the outline shape of the base 11 includes but is not limited to any one of a polyhedron, a truncated pyramid, a prism, a frustum or a cylinder.

[0057] For example, the outline shape of the base 11 can be a three-dimensional structure surrounded by several polygons.

[0058] The following embodiments are all described schematically using a rectangular parallelepiped as an example.

[0059] In a specific embodiment, please refer to Figures 6 and 7. The outline shape of the base 11 is, for example, a rectangular parallelepiped (hexahedron). The rectangular parallelepiped base 11 has a top surface, a bottom surface and four side surfaces. The top surface of the rectangular parallelepiped is the liquid inlet surface 11d, and the bottom surface is provided with a first electrode 13 and a second electrode 14. The two large side surfaces of the four side surfaces are atomizing surfaces 11c. In this way, not only the design difficulty of the atomizing surface 11c can be reduced, but also the total area of ​​the atomizing surface 11c can be significantly increased, and the atomization amount can be significantly improved. In addition, it is also beneficial to the electrical connection between the power supply component of the aerosol generating device and the first electrode 13 and the second electrode 14, and can avoid the power supply component damaging the atomizing surface 11c.

[0060] In some embodiments, the non-atomizing surface 11 a opposite to the connecting region 15 a is a liquid inlet surface 11 d , and the aerosol-generating substrate can flow from the liquid inlet surface 11 d to the atomizing surface 11 c .

[0061] Specifically, referring to Figures 2 to 7, the connection area 15a of the first electrode 13 and the second electrode 14 are both arranged on the bottom surface of the substrate 11, and the top surface of the substrate 11 is the liquid inlet surface 11d. The aerosol generating matrix can flow from the liquid inlet surface 11d to the atomization surface 11c.

[0062] The structure of the heating element can be a continuous film, a porous mesh or a strip. The material, shape and size of the heating element can be set as needed.

[0063] It should be noted that the specific structure of the heating element is not limited here, and the heating element includes but is not limited to a heating sheet, a heating film, a heating net, etc. The following embodiments are all illustrated by taking the heating element as a heating film as an example.

[0064] It should be noted that, in this embodiment, the aerosol generating matrix is ​​liquid. The liquid aerosol generating matrix can be transferred from the liquid inlet surface 11d of the matrix 11 to the heating element on the atomization surface 11c through the capillary force of the matrix 11. The heating element generates heat to heat and atomize the aerosol generating matrix.

[0065] In some embodiments, referring to FIG. 3 and FIG. 7 , there are two atomizing surfaces 11 c , and the two atomizing surfaces 11 c are disposed opposite to each other.

[0066] By providing two atomizing surfaces 11c, the total area of ​​the atomizing surfaces 11c can be significantly increased, significantly improving the atomization volume. Moreover, the two atomizing surfaces 11c are arranged opposite each other, which is more conducive to the flow of aerosol and allows for full and uniform mixing with air, thus improving the taste and thus the user experience.

[0067] In some embodiments, referring to FIG. 6 and FIG. 7 , the electrode 15 includes a connection region 15 a and at least one turning region 15 b .

[0068] That is, the electrode 15 may include one connection region 15a and one turning region 15b, or may include one connection region 15a and two turning regions 15b.

[0069] In some embodiments, referring to FIG. 6 and FIG. 7 , both ends of the connection area 15 a are connected to the turning areas 15 b , and the turning areas 15 b at both ends are electrically connected to the heating elements 12 on the two atomizing surfaces 11 c , respectively.

[0070] The two ends of the first electrode 13 are electrically connected to the heating elements 12 on the two atomizing surfaces 11c, and the two ends of the second electrode 14 are electrically connected to the heating elements 12 on the two atomizing surfaces 11c. The two atomizing surfaces 11c can share a set of electrodes to achieve electrical contact steering on both sides of the atomizing surfaces 11c.

[0071] In other words, the heating elements 12 on the two atomizing surfaces 11c share the first electrode 13 and the second electrode 14, meaning that the heating elements 12 on the two atomizing surfaces 11c are connected in parallel. This ensures consistent atomization efficiency for the heating elements 12 on the two atomizing surfaces 11c, thereby helping to maintain a consistent taste. Furthermore, the fact that the heating elements 12 on the two atomizing surfaces 11c share the first electrode 13 and the second electrode 14 further facilitates electrical connection between the power supply assembly of the aerosol generating device and the first and second electrodes 13, 14, and also reduces the number of components, thereby lowering costs.

[0072] In some embodiments, referring to Figures 2 to 4, the atomizer 100 includes a liquid storage space 100a, an air outlet channel 52a, an atomizer seat assembly 20, a first conductive member 30, a second conductive member 40, and an atomizer core 10 of any embodiment of the present disclosure. The atomizer seat assembly 20 is provided with an atomizing chamber 21b that is connected to the air outlet channel 52a. The atomizer core 10 is disposed in the atomizing chamber 21b. The liquid storage space 100a is in liquid communication with the atomizer core 10. The first conductive member 30 is electrically connected to the first electrode 13. The second conductive member 40 is electrically connected to the second electrode 14.

[0073] Illustratively, the atomizer seat assembly 20 is provided with a liquid inlet channel 21 a , one end of the liquid inlet channel 21 a passes through the top wall of the atomizer seat assembly 20 and is connected to the liquid storage space 100 a , and the other end is in liquid communication with the liquid inlet surface 11 d .

[0074] The number of the liquid inlet channels 21 a is not limited here, for example, it can be one or more.

[0075] The liquid storage space 100a is used to store the aerosol-generating substrate to be used.

[0076] The liquid storage space 100 a is in liquid communication with the atomizer core 10 , that is, the aerosol-generating substrate in the liquid storage space 100 a can be directed to the atomizer core 10 through the liquid inlet channel 21 a to be atomized and generate aerosol.

[0077] Referring to Figures 2 to 4 , the atomizer core 10 is disposed within the atomizer chamber 21b. Specifically, the atomizer core 10 is disposed at the extended end of the liquid inlet channel 21a. The liquid inlet channel 21a is used to direct the aerosol-generating substrate in the lower liquid reservoir to the atomizer core 10. The atomizer core 10 is used to absorb and heat the atomized aerosol-generating substrate to generate aerosol.

[0078] The atomizing core 10 blocks the flow of the aerosol-generating substrate in the liquid inlet channel 21 a , that is, the aerosol-generating substrate does not flow directly into the atomizing chamber 21 b .

[0079] The air outlet channel 52a is communicated with the atomizing chamber 21b, and the generated aerosol is discharged through the air outlet channel 52a for use.

[0080] The atomizer core 10 of the atomizer 100 provided in the embodiment of the present disclosure includes a base 11, a heating element 12, and an electrode 15. The outer peripheral surface of the base 11 includes an atomizing surface 11c and a non-atomizing surface 11a. A heating element 12 is provided on each atomizing surface 11c. The electrode 15 includes a connection area 15a and a turning area 15b. The connection area 15a is provided on the non-atomizing surface 11a, and the turning area 15b is provided on the atomizing surface 11c and is electrically connected to the heating element 12. In other words, the turning area 15b is used to realize the turning of the electrode 15 from the non-atomizing surface 11a to the atomizing surface 11c, with the purpose of realizing the electrical connection between the connection area 15a and the heating element 12 on the atomizing surface 11c. In this way, the connection structure between the atomizer core 10 and the power supply assembly is simplified, and the conductive element is electrically connected to the electrode 15 on the connection area 15a of the non-atomizing surface 11a, thereby preventing the conductive element from damaging the atomizing surface 11c and the heating element 12.

[0081] In some embodiments, referring to Figures 2 to 7 , an atomizing surface 11c is disposed on a side surface of the base 11, a connecting region 15a is disposed on the bottom surface of the base 11, and a liquid inlet surface 11d is disposed on the top surface of the base 11. The atomizer assembly 20 is provided with a liquid inlet channel 21a. One end of the liquid inlet channel 21a extends through the top wall of the atomizer assembly 20 and connects to the liquid storage space 100a, while the other end is in liquid communication with the liquid inlet surface 11d.

[0082] Taking the base 11 as a rectangular parallelepiped as an example, the atomizing surface 11c is arranged on the side of the rectangular parallelepiped, and the connection areas 15a of the first electrode 13 and the second electrode 14 are both arranged on the bottom surface of the base 11, for respectively abutting and connecting with the first conductive member 30 and the second conductive member 40. In this way, the contact between the atomizing surface 11c and the first conductive member 30 can be turned through the turning area 15b of the first electrode 13, and the contact between the atomizing surface 11c and the second conductive member 40 can be turned through the turning area 15b of the second electrode 14, that is, the turning area 15b realizes the turning of the electrode 15 from the non-atomizing surface 11a to the atomizing surface 11c, so as to achieve contact between the connection area 15a and the heating element 12 on the atomizing surface 11c. In this way, the connection structure between the atomizing core 10 and the power supply assembly is simplified.

[0083] In some embodiments, referring to Figures 3 and 7 , there are two atomizing surfaces 11 c, and the two atomizing surfaces 11 c are disposed opposite each other. Both ends of the connection region 15 a are connected to a turning region 15 b, and the turning regions 15 b at both ends are electrically connected to the heating elements 12 on the two atomizing surfaces 11 a.

[0084] The turning areas 15b at both ends of the connection area 15a of the first electrode 13 are electrically connected to the heating elements 12 on the two atomizing surfaces 11c respectively. The turning areas 15b at both ends of the connection area 15a of the second electrode 14 are electrically connected to the heating elements 12 on the two atomizing surfaces 11c respectively.

[0085] By providing two atomizing surfaces 11c, the total area of ​​the atomizing surfaces 11c can be significantly increased, significantly improving the atomization volume. Moreover, the two atomizing surfaces 11c are arranged opposite each other, which is more conducive to the flow of aerosol and allows for full and uniform mixing with air, thus improving the taste and thus the user experience.

[0086] The turning areas 15b at both ends of the connection area 15a of the first electrode 13 are respectively electrically connected to the heating elements 12 on the two atomizing surfaces 11c, and the turning areas 15b at both ends of the connection area 15a of the second electrode 14 are respectively electrically connected to the heating elements 12 on the two atomizing surfaces 11c.
