[0036] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "top", "bottom" and the like indicate positions or location relationships based on the attached Figure 2 To Attachment Figure 4 The orientation or position relationship shown in the figure is only for the convenience of describing the embodiments of the present application and simplifying the description, and does 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 embodiments of the present application. The present application is further described in detail below in conjunction with the drawings and specific embodiments.

[0037] One aspect of the present application provides an aerosol generating device. Figures 1 to 4 , including a power supply assembly and an atomizer 100 provided in any embodiment of the present application. The power supply assembly is electrically connected to the 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 encapsulated in the same housing and are relatively non-detachable.

[0038] The power supply device is mainly used to supply power to the atomizer 100 and control the opening or closing of the entire aerosol generating device, and the atomizer 100 is mainly used to contain an aerosol generating substrate and heat and atomize the aerosol generating substrate after power is turned on. The aerosol generating substrate includes, but is not limited to, materials used for medical treatment, health preservation, health, beauty, and the like.

[0039] In some embodiments, the atomizer 100 and the power supply device can be mechanically and electrically connected together along the axial direction. Furthermore, the atomizer 100 and the power supply device can be connected together in a detachable manner such as a magnetic connection, a threaded connection, a snap connection, etc. The atomizer 100 and the power supply device can be replaced or upgraded separately, reducing the replacement cost and saving user expenses. Of course, in other embodiments, the atomizer 100 and the power supply device can also be connected together in a non-detachable manner.

[0040] In addition, 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 column, a square box, or a polygonal column. For example, in this embodiment, the cross section of the lower end of the atomizer 100 is roughly rectangular, and the cross section of the upper part of the atomizer is closer to an ellipse.

[0041] It should be noted that the specific type of the aerosol generating device provided in the embodiments of the present application 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.

[0042] In some embodiments, the aerosol generating device of the present application embodiment, please refer to Figures 1 to 4 , including a power supply assembly and the atomizer core 10 provided in any embodiment of the present application. The electrode column of the power supply assembly is electrically connected to the electrode 15.

[0043] Another aspect of the embodiment of the present application provides an atomizer 100, including a conductive member and an atomizer core 10 provided in any embodiment of the present application. In the present embodiment, the conductive member includes a first conductive member 30 and a second conductive member 40; accordingly, the atomizer core 10 has an electrode 15, including 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 the power supply assembly through the first conductive member 30 and the second conductive member 40. That is, 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 through the first conductive member 30 and the second conductive member 40, so as to realize the power supply assembly to supply power to the atomizer core 10 of the atomizer 100 and control the opening or closing of the entire aerosol generating device, and the atomizer core 10 can heat the atomized aerosol generating substrate to form an aerosol when it is powered on.

[0044] 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) product, is generally a downward atomization (i.e., the atomizing surface faces the bottom of the atomizer) due to the limitation of volume space. In the above two mainstream methods, the aerosol generated by atomization needs to be bent to finally reach the user, so the aerosol loss is large, which makes it difficult to improve the atomization efficiency and taste. The present application adopts the side atomization method (i.e., 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.

[0045] The atomizer core 10 provided in the embodiment of the present application is shown in FIG. Figures 2 to 7, including 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 arranged on at least one atomizing surface 11c, and the heating element 12 is used to heat the atomized aerosol generating matrix. The electrode 15 includes a connecting area 15a and a turning area 15b, the connecting area 15a is arranged 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.

[0046] The outer peripheral surface of the substrate 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 arranged on different outer peripheral surfaces of the substrate 11 .

[0047] Exemplarily, the electrode 15 includes a first electrode 13 and a second electrode 14 .

[0048] The connection area 15a is arranged on the non-atomized surface 11a, and the turning area 15b extends from the connection area 15a and turns to the atomized surface 11c. The turning area 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 realize the electrical connection between the connection area 15a and the heating element 12 on the atomized surface 11c. The conductive element contacts the connection area 15a on the non-atomized surface 11a to realize the electrical connection, so as to avoid the conductive element from damaging the atomized surface 11c and the heating element 12.

[0049] The outer peripheral surface of the substrate 11 includes at least one atomized surface 11c, which means that the substrate 11 may include an atomized surface 11c (such as Figure 4 and Figure 6 ), or may include a plurality of atomized surfaces 11c (such as Figure 3 and Figure 7 ).

[0050] The multiple mentioned in the embodiments of the present application refers to a number of two or more.

[0051] In some embodiments, the atomized surface 11 c is disposed on a side surface of the substrate 11 , and the connection area 15 a of the electrode 15 is disposed on a bottom surface of the substrate 11 .

[0052] 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 area 15a of the first electrode 13 and the second electrode 14 are both arranged on the bottom surface of the substrate 11, which are used to respectively abut and connect with the first conductive member 30 and the second conductive member 40. In this way, the contact point 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 point 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.

[0053] 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 be respectively connected with the first conductive member 30 and the second conductive member 40. In this way, the contact point 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 point between the atomized surface 11c and the second conductive member 40 can be turned through the turning area 15b of the second electrode 14.

[0054] It should be noted that the material of the substrate 11 is not limited here. 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, and the electrically insulating material includes but is not limited to ceramics, glass, polyimide, etc. The following embodiments are all illustrated by taking the substrate 11 as ceramic as an example.

[0055] 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.

[0056] In the embodiment of the present application, the first electrode 13 and the second electrode 14 are formed on the substrate 11 by means of drilling and grouting.

[0057] The atomizer core 10 provided in the embodiment of the present application includes a substrate 11, a heating element 12 and an electrode 15. The outer peripheral surface of the substrate 11 includes an atomizing surface 11c and a non-atomizing surface 11a, and a heating element 12 is arranged 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 arranged on the non-atomizing surface 11a, and 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. That is, 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, and the purpose is to realize 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, so as to avoid the conductive element from damaging the atomizing surface 11c and the heating element 12.

[0058] It should be noted that the specific contour shape of the substrate 11 is not limited here, and the contour shape of the substrate 11 includes but is not limited to any one of a polyhedron, a prism, a prism, a frustum or a cylinder.

[0059] For example, the outline shape of the base body 11 may be a three-dimensional structure surrounded by a number of polygons.

[0060] The following embodiments are all described by taking a rectangular parallelepiped as an example.

[0061] In a specific embodiment, please refer to Figure 6 and Figure 7 The outline shape of the substrate 11 is, for example, a rectangular parallelepiped (hexahedron), and the rectangular parallelepiped substrate 11 has a top surface, a bottom surface and four side surfaces, the top surface of the rectangular parallelepiped is a liquid inlet surface 11d, the bottom surface is provided with a first electrode 13 and a second electrode 14, and two large side surfaces of the four side surfaces are atomization surfaces 11c. In this way, not only the design difficulty of the atomization surface 11c can be reduced, but also the total area of ​​the atomization 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 atomization surface 11c.

[0062] In some embodiments, the non-atomizing surface 11a opposite to the connecting region 15a is a liquid inlet surface 11d, and the aerosol generating substrate can flow from the liquid inlet surface 11d to the atomizing surface 11c.

[0063] Specifically, see 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, and the aerosol generating matrix can flow from the liquid inlet surface 11d to the atomization surface 11c.

[0064] 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 required.

[0065] 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.

[0066] 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.

[0067] In some embodiments, see Figure 3 and Figure 7 The number of the atomizing surfaces 11c is two, and the two atomizing surfaces 11c are arranged opposite to each other.

[0068] By providing two atomizing surfaces 11c, the total area of ​​the atomizing surface 11c can be significantly increased, and the atomization amount can be significantly improved. Moreover, the two atomizing surfaces 11c are arranged opposite to each other, which is more conducive to the flow of aerosol and full and uniform mixing with air, improving the taste and further improving the user experience.

[0069] In some embodiments, see Figure 6 and Figure 7 The electrode 15 includes a connection region 15a and at least one turning region 15b.

[0070] 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.

[0071] In some embodiments, see Figure 6 and Figure 7 Both ends of the connection area 15a are connected to the turning areas 15b, and the turning areas 15b at both ends are electrically connected to the heating elements 12 on the two atomizing surfaces 11c respectively.

[0072] 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 the electrical contact of the two-sided atomizing surfaces 11c.

[0073] That is to say, the heating elements 12 on the two atomization surfaces 11c share the first electrode 13 and the second electrode 14, that is, the heating elements 12 on the two atomization surfaces 11c are in parallel, so that the atomization efficiency of the heating elements 12 on the two atomization surfaces 11c can be consistent, which is conducive to maintaining the consistency of taste. In addition, the heating elements 12 on the two atomization surfaces 11c share the first electrode 13 and the second electrode 14, which is more conducive 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 also reduce parts, thereby reducing costs.

[0074] In some embodiments, see 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 application. The atomizer seat assembly 20 is provided with an atomizer chamber 21b connected to the air outlet channel 52a. The atomizer core 10 is arranged in the atomizer 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.

[0075] Exemplarily, the atomizer seat assembly 20 is provided with a liquid inlet channel 21a, one end of the liquid inlet channel 21a passes through the top wall of the atomizer seat assembly 20 and is connected to the liquid storage space 100a, and the other end is in liquid communication with the liquid inlet surface 11d.

[0076] The number of the liquid inlet channels 21 a is not limited here, for example, it can be one or more.

[0077] The liquid storage space 100a is used to store the aerosol generating substrate to be used.

[0078] The liquid storage space 100a is in liquid communication with the atomizer core 10, that is, the aerosol-generating substrate in the liquid storage space 100a can be directed to the atomizer core 10 through the liquid inlet channel 21a to be atomized and generate aerosol.

[0079] See also Figures 2 to 4 The atomizing core 10 is disposed in the atomizing chamber 21b. Specifically, the atomizing core 10 is disposed at the extended end of the liquid inlet channel 21a. The liquid inlet channel 21a is used to guide the aerosol generating substrate in the lower liquid tank to the atomizing core 10. The atomizing core 10 is used to absorb and heat the atomized aerosol generating substrate and generate aerosol.

[0080] 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 .

[0081] 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.

[0082] The atomizer core 10 of the atomizer 100 provided in the embodiment of the present application includes a substrate 11, a heating element 12 and an electrode 15. The outer peripheral surface of the substrate 11 includes an atomizing surface 11c and a non-atomizing surface 11a, and a heating element 12 is arranged on each atomizing surface 11c. The electrode 15 includes a connecting area 15a and a turning area 15b. The connecting area 15a is arranged on the non-atomizing surface 11a, and the turning area 15b is arranged on the atomizing surface 11c and is electrically connected to the heating element 12. That is to say, 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, and the purpose is to realize the electrical connection between the connecting 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, and the conductive element is electrically connected to the electrode 15 on the connecting area 15a of the non-atomizing surface 11a, so as to avoid the conductive element from damaging the atomizing surface 11c and the heating element 12.

[0083] In some embodiments, see Figures 2 to 7 The atomizing surface 11c is arranged on the side of the base 11, the connecting area 15a is arranged on the bottom surface of the base 11, and the top surface of the base 11 is provided with a liquid inlet surface 11d. The atomizing seat assembly 20 is provided with a liquid inlet channel 21a, one end of the liquid inlet channel 21a passes through the top wall of the atomizing seat assembly 20 and is connected to the liquid storage space 100a, and the other end is in liquid communication with the liquid inlet surface 11d.

[0084] Taking the substrate 11 as a rectangular parallelepiped as an example, the atomizing surface 11c is arranged on the side of the rectangular parallelepiped, and the connecting areas 15a of the first electrode 13 and the second electrode 14 are both arranged on the bottom surface of the substrate 11, and are used to respectively abut and connect with the first conductive member 30 and the second conductive member 40. In this way, the contact point 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 point 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 realize the contact between the connecting 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.

[0085] In some embodiments, see Figure 3 and Figure 7 The number of atomizing surfaces 11c is two, and the two atomizing surfaces 11c are arranged opposite to each other. Both ends of the connecting area 15a are connected to the turning area 15b, and the turning areas 15b at both ends are electrically connected to the heating elements 12 on the two atomizing surfaces 11a respectively.

[0086] 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, and 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.

[0087] By providing two atomizing surfaces 11c, the total area of ​​the atomizing surface 11c can be significantly increased, and the atomization amount can be significantly improved. Moreover, the two atomizing surfaces 11c are arranged opposite to each other, which is more conducive to the flow of aerosol and full and uniform mixing with air, improving the taste and further improving the user experience.

[0088] 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 atomization surfaces 11c, respectively, and 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 atomization surfaces 11c, respectively. That is, the heating elements 12 on the two atomization surfaces 11c share the first electrode 13 and the second electrode 14, that is, the heating elements 12 on the two atomization surfaces 11c are in parallel, so that the atomization efficiency of the heating elements 12 on the two atomization surfaces 11c can be made consistent, which is conducive to maintaining the consistency of taste. In addition, the heating elements 12 on the two atomization surfaces 11c share the first electrode 13 and the second electrode 14, which is more conducive 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 also reduce parts, thereby reducing costs.

[0089] In some embodiments, see Figures 2 to 4 The atomizer 100 includes a housing 50 having a cavity 50a. At least a portion of the atomizer seat assembly 20 is disposed in the cavity 50a, and defines a liquid storage space 100a between the atomizer seat assembly 20 and the cavity wall of the cavity 50a.

[0090] At least part of the atomizer seat assembly 20 is disposed in the cavity 50a. Part of the structure of the atomizer seat assembly 20 may be disposed in the cavity 50a, or the entire structure of the atomizer seat assembly 20 may be disposed in the cavity 50a.

[0091] See also Figures 2 to 4 The atomizer seat assembly 20 includes an atomizer seat 21 and a sealing member 22 sleeved on the atomizer seat 21. The sealing member 22 is sealed and clamped between the atomizer seat 21 and the cavity wall of the cavity 50a to seal the installation gap between the atomizer seat 21 and the cavity wall of the cavity 50a.

[0092] In some embodiments, see Figures 2 to 4 The housing 50 includes an outer shell 51 and an air outlet pipe 52. The outer shell 51 is formed with a cavity 50a, and the air outlet pipe 52 is formed with an air outlet channel 52a. The air outlet channel 52a is used to discharge the aerosol in the atomization chamber 21b.

[0093] Specifically, the air outlet pipe 52 is arranged along the top-bottom direction of the atomizer 100 , that is, the air outlet channel 52 a is arranged along the top-bottom direction of the atomizer 100 .

[0094] For example, in some embodiments, the housing 51 and the air outlet pipe 52 may be an integrated structure, for example, integrally injection molded. The integrated housing 51 and the air outlet pipe 52 can reduce the number of parts, reduce assembly time, and improve assembly efficiency.

[0095] In some other embodiments, the housing 51 and the air outlet pipe 52 may also be a split structure to facilitate production.

[0096] In some other embodiments, the atomizer 100 further includes a suction member. The suction member is disposed at one end of the air outlet pipe 52 away from the atomization chamber 21b.

[0097] The suction piece is, for example, a nozzle, that is, the user can inhale the aerosol through the nozzle.

[0098] For example, in some embodiments, the air outlet pipe 52 and the suction piece may be an integrated structure, for example, integrally injection molded. The integrated air outlet pipe 52 and the suction piece can reduce the number of parts, reduce assembly time, and improve assembly efficiency.

[0099] In other embodiments, the air outlet pipe 52 and the suction member may also be a split structure to facilitate production.
