[0100] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0101] Figure 1 A schematic structural diagram of a heating component in an embodiment of the present application is shown; Figure 2 Shown Figure 1 For ease of description, the accompanying drawings only show structures related to the embodiments of the present application.

[0102] See attached Figure 1 In one embodiment of the present application, a heating element 100 is provided, comprising an oil guide 10 and a heating element 20, wherein the heating element 20 is in contact with the oil guide 10. The heating element 100 of the present application is applied to an aerosol generating device 400, specifically to an atomizer 300 of the aerosol generating device 400. In other embodiments, the heating element 100 may also be applied to other devices suitable for the heating element 100, without limitation herein.

[0103] Specifically in the embodiment of the present application, the oil guide member 10 may include oil guide cotton, or other porous structures with adsorption capacity, which is not limited here. The oil guide member 10 is in the shape of an elongated strip, specifically, a rectangular shape.

[0104] The heating element 20 may include a metal heating element. The metal heating element has a simple manufacturing process, good heating effect, and low cost. In other embodiments, the heating element 20 may also include a metal ceramic heating element or a glass heating element, etc., which is not limited here.

[0105] The heating element 20 and the oil guide element 10 are in contact with each other to form an atomizing surface. When the heating element 20 is heated, the atomized liquid from the oil guide element 10 is atomized to form an aerosol.

[0106] Furthermore, the heating component 100 further includes a base 30 having a receiving groove 31. The oil guide member 10 is at least partially disposed in the receiving groove 31. The heating element 20 is detachable relative to the base 30 and is clamped and positioned between the oil guide member 10 and the groove wall of the receiving groove 31 along a first direction, so that one side of the heating element 20 contacts the oil guide member 10. Specifically, the first direction is Figure 2 The X direction shown may specifically be the thickness direction of the oil guide member 10 .

[0107] In actual installation, the heating element 20 can be placed in the receiving groove 31 first, and then the oil guide member 10 can be installed in the receiving groove 31, and located between the heating element 30 and the groove wall of the receiving groove 31, so that one side of the oil guide member 10 can fit tightly with the heating element 30 to form an atomizing surface, and the other side of the oil guide member 10 is restricted by the groove wall of the receiving groove 31, so the heating element 20 can be fixed on the base 30 by squeezing the heating element 20.

[0108] In this way, ceramic heating elements do not need to be used, thereby simplifying the manufacturing process, and the heating element 20 is positioned between the oil guide member 10 and the base 30 by clamping, without the need for winding, so that the volume of the oil guide member 10 is further increased, and the heating element 20 will not be deformed, which is also convenient for assembly.

[0109] In order to allow the atomized aerosol to be smoothly discharged from the heating component 100 , in the embodiment of the present application, the base 30 further has a first aerosol outlet 32 ​​connected to the receiving groove 31 , and the heating element 20 at least partially covers the first aerosol outlet 32 ​​.

[0110] Optionally, the first aerosol outlet 32 ​​is located on the side of the heating element 20 facing away from the oil guide element 10. In other words, the first aerosol outlet 32 ​​is arranged opposite to the atomization surface. In this way, the atomized aerosol can quickly reach the first aerosol outlet 32.

[0111] Furthermore, the heating element 20 is provided with a plurality of smoke guide holes, which connect the first aerosol outlet 32 ​​and the oil guide element 10. In this way, the aerosol after atomization can be guided to the first aerosol outlet 32 ​​through the plurality of smoke guide holes and discharged smoothly.

[0112] In some embodiments, the heating element 20 is in a grid-like shape. The plurality of smoke-guiding holes are the grid holes on the grid-like heating element 20. The grid-like heating element 20 not only allows for uniform heating, but also allows for rapid and uniform discharge of the aerosol after atomization.

[0113] In some embodiments, the base 30 includes a first side body 33, and the receiving groove 31 is formed on one side of the first side body 33. The heating element 20 is clamped and positioned along the first direction between the oil guide member 10 and the first side body 33. By providing the first side body 33 to cooperate with the oil guide member 10, the method for clamping and positioning the heating element 20 is simple.

[0114] Furthermore, a first aerosol outlet 32 ​​is provided on the first side body 33. Since the first side body 33 can be directly attached to the heating element 20, providing the first aerosol outlet 32 ​​on the first side body 33 allows aerosol to be discharged smoothly from the first aerosol outlet 32 ​​and also makes the structure of the base 30 more compact.

[0115] In some embodiments, the base 30 further includes a second side body 34, which is spaced apart from and opposite to the first side body 33 along a first direction, with a receiving groove 31 formed between the first side body 33 and the second side body 34. Providing separate first and second side bodies 33, 34 facilitates placement of the oil guide member 10 within the receiving groove 31.

[0116] Furthermore, the second side body 34 is provided with a second aerosol outlet 341 communicating with the receiving groove 31 , and the heating element 20 at least partially covers the second aerosol outlet 341 . In this way, aerosol can also be smoothly discharged from the heating component 100 through the second aerosol outlet 341 .

[0117] In some embodiments, a first opening 35 and a second opening 36 are defined between the first side body 33 and the second side body 34 on both sides of the receiving groove 31 along the second direction. The two ends of the oil guide member 10 protrude from the first opening 35 and the second opening 36 to the outside of the base 30, respectively. Specifically, the first direction is perpendicular to the second direction, and the second direction is Figure 2 The Y direction shown can specifically be the lengthwise direction of the oil guide member 10. This facilitates placement of the oil guide member 10 while also ensuring sufficient contact between the oil and the oil, enhancing the oil guiding effect. In other embodiments, one of a first opening 35 and a second opening 36 can be defined on one side of the receiving groove 31 along the second direction, between the first side body 33 and the second side body 34. One end of the oil guide member 10 protrudes from the first opening 35 or the second opening 36 to the outside of the base 30.

[0118] In some embodiments, at least one of the first side body 33 and the second side body 34 includes at least two side posts 331 spaced apart from each other along the second direction, with a first aerosol outlet 32 ​​formed between each pair of adjacent side posts 331. Providing multiple side posts 331 simplifies defining the first aerosol outlet 32 ​​and allows the side body 33 to have a certain degree of elasticity. This allows for elastic deformation when clamping the heating element 20, thereby providing a better clamping effect on the heating element 20 and improving clamping stability.

[0119] like Figure 4 and Figure 5 As shown, in other embodiments, at least one of the first side body 33 and the second side body 34 is recessed along the first direction toward the side away from the heating element 20 to form a first aerosol outlet 32 ​​on the side that clamps the heating element 20. By recessing the first side body 33, not only the first aerosol outlet 32 ​​is formed, but also a channel connected to the first aerosol outlet 32 ​​is formed, so that the aerosolized aerosol can be discharged in a centralized manner.

[0120] In some embodiments, the portion of the second side body 34 that contacts the oil guide member 10 covers the heating element 20 along the first direction toward the projection area of ​​the heating element 20. Thus, due to the blocking effect of the second side body 34, the aerosol can only be discharged from the first aerosol outlet 32, thereby preventing the aerosol from leaking and affecting the inhalation effect.

[0121] In some embodiments, the heating element 20 includes two heating elements 21, which are arranged opposite each other and spaced apart along a first direction. One heating element 21 is clamped between the oil guide member 10 and the first side member 33 along the first direction, and the other heating element 21 is clamped between the oil guide member 10 and the second side member 34 along the first direction. The oil guide member 10 is clamped between the two heating elements 21. By providing multiple heating elements 21 in contact with the oil guide member 10, the atomization area can be increased.

[0122] Furthermore, the heating element 20 further includes an intermediate connector 22, which connects the two heating elements 21. The intermediate connector 22 and the two heating elements 21 enclose a heating groove 23, and the oil guide member 10 is at least partially disposed within the heating groove 23. The provision of the intermediate connector 22 can integrate the two heating elements 20, improving installation efficiency. In addition, the provision of the intermediate connector 22 can further increase the contact area between the heating element 20 and the oil guide member 10, thereby increasing the atomization area.

[0123] In some embodiments, the base 30 further includes a substrate 37, and the first side body 33 and the second side body 34 are both connected to opposite sides of the base 37 along the first direction, and the base 37, the first side body 33 and the second side body 34 enclose a receiving groove 31. By providing the base 37, the heating element 20 and the oil guide member 10 can be supported so that they are stably arranged on the base 30. Furthermore, the intermediate connecting member 22 is connected to the same side of the heating element 21 and is limited between the oil guide member 10 and the substrate 37. By limiting the intermediate connecting member 22 between the oil guide member 10 and the substrate 37, the positioning stability of the heating element 20 on the base 30 can be further improved, and it is also conducive to simplifying the assembly process.

[0124] Specifically, the intermediate connector 22 includes multiple intermediate connectors 22, which are spaced apart along the second direction. Preferably, there are two intermediate connectors 22. This improves the connection reliability between the two heating elements 21. When the intermediate connector 22 is positioned between the oil guide member 10 and the base 37, the increased contact area between the intermediate connector 22, the oil guide member 10, and the base 37 further enhances positional reliability. More specifically, the intermediate connector 22 is strip-shaped.

[0125] Furthermore, a heating element 21 may be provided between two adjacent intermediate connecting members 22. In this way, the contact area between the heating element 20 and the oil guide member 10 can be further increased, thereby increasing the atomization area.

[0126] Furthermore, the base 37 is provided with a third aerosol outlet communicating with the receiving groove 31, and the heating element 20 at least partially covers the third aerosol outlet. In this way, the emission efficiency of the aerosolized aerosol can be further improved.

[0127] In some embodiments, the portion of the heating element 20 that contacts the oil guide member 10 is in a sheet-like shape. Compared to conventional spiral heating elements 20, sheet-like heating elements 20 can increase the contact area with the oil guide member 10 and provide more stable contact between the heating element 20 and the oil guide member 10. Specifically, both heating elements 21 are in a sheet-like shape.

[0128] See Figure 3 and Figure 4 In some embodiments, the base 30 has a positioning portion 38, and the heating element 20 has a matching portion 24. The matching portion 24 can cooperate with the positioning portion 38 to position the heating element 20 on the base 30. In addition to being clamped and positioned between the oil guide member 10 and the base 30, the positioning portion 38 can also be additionally provided on the base 30 to pre-position the heating element 20 before being clamped and positioned between the oil guide member 10 and the base 30, thereby improving the installation stability of the heating element 20.

[0129] Please continue reading Figure 4Specifically, one of the positioning portion 38 and the matching portion 24 includes a positioning groove, and the other includes a positioning protrusion that matches the positioning groove. The positioning groove and the positioning protrusion match the positioning method simple and reliable, and is conducive to assembly.

[0130] In some embodiments, the positioning portions 38 include at least two, spaced apart in sequence along the second direction. The mating portions 24 also include at least two, with all positioning portions 38 corresponding to all mating portions 24. Providing multiple positioning portions 38 and mating portions 24 can improve positioning reliability. In the embodiment of the present application, the positioning portions 38 are provided on the side body 33, specifically on the side pillar 331.

[0131] Please continue reading Figure 3 Furthermore, the distance between two of the positioning portions 38 gradually decreases along the first direction toward the side away from the heating element 20. In this way, an "eight"-shaped positioning shape can be formed, which, when engaged with the engaging portion 24, can securely fasten the heating element 20 to the base 30.

[0132] In the embodiment of the present application, there are two positioning portions 38 , and the two positioning portions 38 are arranged at both ends of the heat generating element 20 along the second direction and spaced apart from each other.

[0133] Please continue reading Figure 3 and Figure 4 In some embodiments, the heating element 20 includes a positive pin 25 and a negative pin 26 connected to the heating element 21, and both the positive pin 25 and the negative pin 26 have a mating portion 24. Thus, by utilizing the existing positive pin 25 and the negative pin 26 as a structure for mating with the positioning portion 38 of the base 30, the structure of the heating element 20 can be simplified. Furthermore, generally, both the positive pin 25 and the negative pin 26 need to extend outward from the heating component 100, thereby lengthening the contact length between them and the positioning portion 38, thereby improving positioning reliability.

[0134] Based on the same inventive concept, the present application also provides an atomization assembly 200 .

[0135] First embodiment

[0136] Reference Figures 6 to 10 , Figure 6 A schematic structural diagram of an atomizing assembly according to a first embodiment of the present application is shown; Figure 7 A schematic diagram of the exploded structure of the atomizer assembly of the first embodiment of the present application is shown; Figure 8 A structural schematic diagram showing a portion of the structure of an atomizer assembly according to a first embodiment of the present application; Figure 9 A schematic structural diagram of a support member of an atomizer assembly according to a first embodiment of the present application is shown; Figure 10A structural schematic diagram showing a portion of the structure of an atomization assembly of the first embodiment of the present application.

[0137] The atomizer assembly 200 includes the heating assembly 100 and a support member 210 in any of the above embodiments. The support member 210 has a first air flow channel 211 . The heating element 20 and at least part of the oil guide member 10 are located in the first air flow channel 211 .

[0138] In this way, the aerosol atomized by the heating element 20 can enter the first air flow channel 211 and then be inhaled by the user.

[0139] It can be understood that the first air flow channel 211 of the present application is in communication with the external air.

[0140] Please continue reading Figure 8 and Figure 9 Furthermore, the base 30 is mounted on the support member 210, the heating element 20 is at least partially exposed outside the base 30, and the receiving groove 31 is connected to the first air flow channel 211. Specifically, the base 30 is detachably mounted on the support member 210.

[0141] In this way, the heating component 100 can be installed as a whole on the support member 210 , which simplifies the installation process, and the atomized aerosol can also smoothly enter the first air flow channel 211 of the support member 210 .

[0142] In the embodiment of the present application, the heating element 20 is exposed from the base 30 on a side facing away from the oil guide element 10 in the first direction, and is spaced apart from the inner wall of the first airflow channel 211 to form an atomization channel. Specifically, the heating element 20 is exposed from the base 30 through at least one of the first aerosol outlet 32, the second aerosol outlet 341, and the third aerosol outlet formed on the base 30. This allows the heating element 20 to directly communicate with the first airflow channel 211, allowing atomized aerosol to quickly enter the first airflow channel, thereby improving the discharge efficiency of the atomized aerosol and preventing leakage.

[0143] In this embodiment, the first air flow channel 211 extends along the third direction, and the third direction intersects the first direction. Optionally, the third direction is perpendicular to the first direction, which can also be understood as the atomizing surface is arranged parallel to the first air flow channel 211. Specifically, the third direction is Figure 2 The Z direction shown may specifically be the height direction of the oil guide member 10. In this way, the resistance of the atomized aerosol flowing into the first air flow channel can be reduced, so that the atomized aerosol can flow into the first air flow channel more smoothly and quickly.

[0144] In this embodiment, the support member 210 is provided with a connecting hole 212 that is connected to the first air flow channel 211, and a portion of the oil guide member 10 extends from the connecting hole 212 to the outside of the support member 210. Providing a portion of the oil guide member 10 extending from the outside of the support member 210 enables the oil guide member 10 to fully contact the oil, thereby improving the oil guiding effect. Specifically, the support member 210 is provided with a connecting hole 212 that is connected to the first air flow channel 211 along the second direction. Since the extending direction of the oil guide member 10 is the second direction that intersects with the first direction, it does not affect the oil guide member 10's clamping of the heating element 20 in the first direction, and the atomized aerosol is not easily leaked from the connecting hole 212.

[0145] Preferably, the support member 210 defines a plurality of communication holes 212, all of which are spaced apart along the circumference of the support member 210. Multiple portions of the oil guide member 10 extend from the plurality of communication holes 212 to the outside of the support member 210. This expands the oil guide range and improves oil guide efficiency. Preferably, the support member 210 includes two communication holes 212 disposed opposite each other along the second direction, with the ends of the oil guide member 10 extending from the two communication holes 212 to the outside of the support member 210.

[0146] Furthermore, a portion of the base 30 protrudes from the connecting hole 212 outside the support member 210 to be supported on the wall of the connecting hole 212. This simplifies the assembly process of the base 30 relative to the support member 210. Specifically, the base 37 of the base 30 protrudes from the side body 33 in the second direction and penetrates the connecting hole 212, and is supported on the wall of the connecting hole 212 in the third direction. Furthermore, a portion of the oil guide member 10 is supported on the portion of the base 30 protruding from the outside of the support member 210. This not only increases the support area of ​​the oil guide member 10 due to the length of the base 37, but also ensures reliable positioning of the base 30 relative to the support member 210 through the interaction between the base 37 and the connecting hole 212.

[0147] Please continue reading Figure 7 In this embodiment, the atomizer assembly 200 also includes a first connecting member 220, which can be mounted on the support member 210 and has a first aerosol channel 221 connected to the first air flow channel 211, wherein the oil guide member 10 is limited between the first connecting member 220 and the support member 210.

[0148] Thus, by constraining the oil guide member 10 between the first connector 220 and the support member 210, the oil guide member 10 can be sufficiently compressed to prevent it from loosening, thereby maintaining close contact with the heating element 20 and improving the atomization effect. Furthermore, the oil guide member 10 also includes the first aerosol passage 221 for circulating the atomized aerosol, thus integrating multiple functions and simplifying the structure of the atomizer assembly 100.

[0149] Furthermore, when a portion of the oil-guiding member 10 extends from the communicating hole 212 outside the support member 210, the first connecting member 220 is sleeved on the outside of the support member 210 to restrain the oil-guiding member 10 outside the support member 210. Providing the first connecting member to restrain the oil-guiding member 10 outside the support member 210 not only expands the first aerosol passage 221 but also simplifies the installation process. Furthermore, the proper installation between the oil-guiding member 10 and the first connecting member 220 can be simultaneously observed, thereby improving the installation reliability of the oil-guiding member 10.

[0150] Specifically, the first connecting member 220 is tubular, and the supporting member 210 is also tubular.

[0151] Furthermore, the oil guide member 10 is in close contact with the first connecting member 220 and the wall of the communicating hole 212. In this way, the aerosol along the atomization is prevented from leaking from the communicating hole 212 and affecting the suction effect.

[0152] Preferably, the oil guiding member 10 is elastic, and the oil guiding member 10 elastically abuts against the hole wall of the communicating hole 212 and the first connecting member.

[0153] In this embodiment, when part of the oil guide member 10 is supported on the part of the base 30 that protrudes from the support member 210, since the base 30 can provide a larger support area, the oil guide member 10 can be reliably confined between the first connecting member 220 and the base 30, further improving the installation reliability of the oil guide member 10.

[0154] In this embodiment, the first connecting member 220 comprises a glass fiber tube, which can be sleeved with the support member 210 and has a first aerosol channel 221. The glass fiber tube can be tightly connected to the support member 210 to prevent the aerosol from leaking therebetween.

[0155] In this embodiment, the atomizer assembly 200 further includes an oil storage member 230, which is disposed outside the support member 210 and the first connecting member 220 and contacts the oil guide member 10. Specifically, the oil storage member 230 is coated on the outside of the support member 210 and the first connecting member 220.

[0156] Furthermore, the oil storage member 230 includes at least two sub-oil storage members 231, all of which can be spliced ​​together to form a first accommodation space for accommodating the support member 210 and the first connecting member 220. This first accommodation space can be in the form of a through hole. By providing multiple spliced ​​sub-oil storage members 231, the oil storage member 230 can be installed more conveniently. Specifically, at least two sub-oil storage members 231 are distributed along the circumference of the support member 210 and the first connecting member 220. Of course, in other embodiments, the oil storage member 230 can also be an integrally formed structure, with one end of the oil storage member 230 having a placement groove or placement hole for accommodating the support member 210 and the first connecting member 220.

[0157] Furthermore, an oil absorption gap is provided between at least two adjacent sub-oil storage members 231, so that aerosols leaked due to accidents can be absorbed.

[0158] Preferably, the oil storage member 230 includes two sub-oil storage members 231 that are assembled with each other along the first direction.

[0159] In this embodiment, at least two adjacent sub-oil reservoirs 231 can clamp at least the portion of the oil-guiding member 10 protruding from the support member 210. This clamping action secures the oil-guiding member 10 relative to the oil reservoir 230, thereby enhancing the aerosol-guiding effect. Specifically, at least one sub-oil reservoir 231 defines a clamping hole, within which at least the portion of the oil-guiding member 10 protruding from the support member 210 is clamped. Preferably, at least the portion of each oil-guiding member 10 protruding from the support member 210 is clamped by two adjacent sub-oil reservoirs 231.

[0160] In this embodiment, the oil storage member 231 includes a porous oil storage member such as oil storage cotton.

[0161] In this embodiment, the atomizer assembly 200 further includes a sealing seat 240 and a base 250. The sealing seat 240 is connected to the end of the first connector 220 away from the support member 210, and the base 250 is connected to the end of the support member 210 away from the first connector 220. A confined space is formed between the sealing seat 240 and the base 250, and the oil reservoir 230 is confined within the confined space. By providing the sealing seat 240 and the base 250, a confined space is formed to confine the oil reservoir 230, thereby making the position of the oil reservoir 230 relative to the oil guide member 10 more reliable, thereby enabling smooth aerosol guidance.

[0162] Furthermore, the sealing seat 240 includes a sealing seat body 241 and a second connecting member 242. The second connecting member 242 is provided on a side of the sealing seat body 241 facing the first connecting member 220. The second connecting member 242 can be sleeved with the first connecting member 220. In this way, a tight connection between the first connecting member 220 and the second connecting member 242 can be achieved.

[0163] Specifically, the second connecting member 242 can be sleeved on the outside of the first connecting member 220. In other embodiments, the second connecting member 242 can be sleeved on the inside of the first connecting member 220, which is not limited here. More specifically, the second connecting member 242 is tubular and has an interference fit with the first connecting member 220.

[0164] It should be noted that the sealing seat 240 further has a second aerosol passage, which is in communication with the first aerosol passage 221. Specifically, the second aerosol passage passes through the sealing seat body 241 and the second connecting member 242.

[0165] In this embodiment, the base 250 includes a base body 251 and a third connecting member 252 . The third connecting member 252 is disposed on a side of the base body 251 facing the supporting member 210 . The third connecting member 252 can be sleeved with the supporting member 210 .

[0166] Specifically, the third connecting member 252 can be sleeved on the outside of the support member 210. In other embodiments, the third connecting member 252 can be sleeved on the inside of the support member 210. More specifically, the second connecting member 242 is tubular, and the third connecting member 252 and the support member 210 have an interference fit.

[0167] It should be noted that the base 250 further has a second airflow channel, which is in communication with the first airflow channel 211. Specifically, the second airflow channel passes through the base body 251 and the third connecting member 252.

[0168] Please continue reading Figure 10 Furthermore, the base 250 is provided with a first air inlet 2511 and a first guide channel 2512, which are connected to the second air flow channel. The first air inlet 2511 is connected to the end of the second air flow channel away from the support member 210, and the first guide channel 2512 is connected to the first air inlet 2511. The extension direction of the first guide channel 2512 intersects the axial direction of the first air inlet 2511. Specifically, the extension direction of the first guide channel 2512 is parallel to the second direction, and the axial direction of the first air inlet 2511 is parallel to the third direction.

[0169] In this embodiment, the base 250 is provided with a through hole for the positive electrode pin 25 and the negative electrode pin 26 to pass through. Preferably, the first air inlet 2511 is a through hole, or the through hole is spaced apart from the first air inlet 2511.

[0170] Please continue reading Figure 7 In this embodiment, the atomizer assembly 200 further includes an atomizer housing 260 , and the heating assembly 100 , the support member 210 , the first connecting member 220 , the oil storage member 230 , the sealing seat 240 and the base 250 are all installed in the atomizer housing 260 .

[0171] Specifically, the atomizing housing 260 includes an oil reservoir 261, and the oil guide 10 is connected to the oil reservoir 261. This allows the aerosol in the oil reservoir 261 to be directed to the heating element 20, allowing for smooth atomization of the aerosol. More specifically, the oil reservoir 230 is disposed within the oil reservoir 261.

[0172] More specifically, the sealing seat 240 and base 250 respectively seal against the inner wall of the atomizing housing 260 along the circumferential direction, defining an oil storage tank 261 between the sealing seat 240, base 250, and atomizing housing 260. Thus, defined by the sealing seat 240, base 250, and atomizing housing 260, the oil reservoir 230 can be securely installed within the oil storage tank 261. Preferably, the atomizing housing 260 is tubular.

[0173] The atomizing assembly 200 of this embodiment can be applied to the atomizer 300 described later. The atomizer 300 can be integrated with the power supply assembly 410 of the aerosol generating device 400 .

[0174] Second embodiment

[0175] Reference Figure 11 , Figure 11 A schematic diagram of the exploded structure of the atomizer assembly of the second embodiment of the present application is shown.

[0176] In this embodiment, the atomizing housing 260 defines a second air inlet 261 that communicates with the first guide channel 2512 of the base 250 . Thus, air can flow from the outside into the first guide channel 2512 through the second air inlet 261 on the atomizing housing 260 and then into the first air inlet 2511 .

[0177] The other structures of the atomizing assembly 200 in this embodiment are the same as those in the first embodiment and will not be described again here.

[0178] The atomizing assembly 200 of this embodiment can be applied to the atomizer 300 described later. The atomizer 300 can be detachably connected to the power supply assembly 410 of the aerosol generating device 400 .

[0179] Based on the same inventive concept, the present application also provides an atomizer 300 .

[0180] First embodiment

[0181] Reference Figure 12 , Figure 12 A schematic structural diagram of an atomizer according to the first embodiment of the present application is shown.

[0182] The atomizer 300 includes the atomization assembly 200 in any of the above embodiments.

[0183] Furthermore, the atomizer 300 further includes a nozzle 310, which is disposed on a side of the sealing seat 240 facing away from the base 250. Specifically, one end of the atomizing housing 260 is provided with a first opening 263 communicating with the interior thereof, and the nozzle 310 is mounted at the first opening 263.

[0184] It can be understood that the suction nozzle 310 has a suction channel 311, and the suction channel 311 is connected to the second aerosol channel.

[0185] In some embodiments, the atomizer 300 further includes a condensation element 320, which is positioned between the sealing seat 240 and the mouthpiece, with its two sides connected to the suction channel 311 and the second aerosol channel, respectively. Preferably, the sealing seat 240, facing the mouthpiece 310, has a first mounting groove that connects to the second aerosol channel, and the condensation element 320 is mounted within the first mounting groove. The condensation element 320 condenses the moisture in the atomized aerosol to form a liquid, thereby improving the customer experience.

[0186] Specifically, the condensation element 320 may include condensation cotton, or may include other components that can have a condensation function, which is not limited here.

[0187] The atomizer 300 of this embodiment can be integrated with the power supply assembly 410 of the aerosol generating device 400 described later.

[0189] Reference Figures 13 to 15 , Figure 13 A schematic diagram of the exploded structure of an atomizer according to a second embodiment of the present application is shown; Figure 14 A schematic structural diagram of the bottom cover of the atomizer according to the second embodiment of the present application is shown; Figure 15 A structural schematic diagram showing another perspective of the bottom cover of the atomizer according to the second embodiment of the present application is shown.

[0190] The atomizer 300 further includes a bottom cover 330 , which is disposed on one side of the base 250 . The bottom cover 330 is provided with a positive electrode pin hole 3301 and a negative electrode pin hole 3302 for the positive electrode pin 25 and the negative electrode pin 26 to pass through.

[0191] In this embodiment, the bottom cover 330 has a first connection portion 3303 and a second connection portion 3304 on the side facing away from the base 250. The first connection portion 3303 is spaced apart from the positive pin hole 3301. The positive pin 25 passes through the positive pin hole 3301 and is bent to the first connection portion 3303. The second connection portion 3304 is spaced apart from the negative pin hole 3302. The negative pin 26 passes through the negative pin hole 3302 and is bent to the second connection portion 3304. The power supply assembly 410 can be connected to the positive pin 25 at the first connection portion 3303 and the negative pin 26 at the second connection portion 3304. By bending the positive pin 25 and the negative pin 26 to connect to the first connection portion 3303 and the second connection portion 3304, the positive pin 25 and the negative pin 26 can be fixed relative to the bottom cover 330, thereby improving the connection reliability between the positive pin 25 and the negative pin 26 and the power supply assembly 410.

[0192] Preferably, the first connection portion 3303 comprises a first connection groove or a first connection hole provided on the side of the bottom cover 330 facing away from the base 250. The second connection portion 3304 comprises a second connection groove or a second connection hole provided on the side of the bottom cover 330 facing away from the base 250. In other embodiments, the first connection portion 3303 and the second connection portion 3304 may also be a first connection boss and a second connection boss provided on the side of the bottom cover 330 facing away from the base 250.

[0193] In this embodiment, the atomizer 300 further includes a positive electrode connection portion 340 and a negative electrode connection portion 350. The positive electrode connection portion 340 is installed in the first connection groove or the first connection hole and is electrically connected to the positive electrode pin 25. The negative electrode connection portion 350 is installed in the second connection groove or the second connection hole and is electrically connected to the negative electrode pin 26. The positive electrode connection portion 340 and the negative electrode connection portion 350 can be electrically connected to the positive electrode contact 411 and the negative electrode contact 412 of the external power supply assembly 410, and the power supply assembly 410 can provide operating power to the heating element 20. In this way, the method of electrically connecting the positive electrode connection portion 340 to the positive electrode pin 25 by arranging it in the first connection groove or the first connection hole is simple and reliable, and the method of electrically connecting the negative electrode connection portion 350 to the negative electrode pin 26 by arranging it in the second connection groove or the second connection hole is simple and reliable.

[0194] Furthermore, a first guide portion 3305 is provided on the side of the bottom cover 330 facing away from the base 250. The first guide portion 3305 is positioned between the positive pin hole 3301 and the first connecting portion 3303 and is used to guide the positive pin 25 to the first connecting portion 3303. This ensures that the positive pin 25 is properly guided to connect with the first connecting portion 3303, simplifying the assembly process and improving assembly efficiency. Preferably, the first guide portion 3305 comprises a first guide groove provided on the side of the bottom cover 3300 facing away from the base 250. More preferably, the first guide groove connects the positive pin hole 3301 and the first connecting groove. This ensures that the positive pin 25 is properly guided to the first connecting portion 3303, constrained by the walls of the first guide groove. Furthermore, since the positive pin 25 is located within the first guide groove, it is protected from damage.

[0195] A second guide portion 3306 is provided on the side of the bottom cover 330 facing away from the base 250. This second guide portion 3306 is positioned between the negative pin hole 3302 and the second connecting portion 3304 and is used to guide the negative pin 26 to the second connecting portion 3304. This ensures that the negative pin 26 is properly guided to connect with the second connecting portion 3303, simplifying the assembly process and improving assembly efficiency. Preferably, the second guide portion 3306 comprises a second guide groove formed on the side of the bottom cover 310 facing away from the base 250. More preferably, the second guide groove connects the positive pin hole 3301 and the second connecting groove. This ensures that the negative pin 26 is properly guided to the second connecting portion 3304, constrained by the walls of the second guide groove. Furthermore, since the negative pin 26 is located within the first guide groove, it is protected from damage.

[0196] In this embodiment, a second opening 264 is defined at one end of the atomizing housing 260 and communicates with the interior thereof. The bottom cover 310 is mounted at the second opening 264. The bottom cover 330 defines a second guide channel 3307, through which the second opening 264 communicates with the first guide channel 2512. Preferably, the second guide channel 3307 extends parallel to the first guide channel 2512. To prevent the first guide channel 2512 from being too deep and thus affecting the seal between the base 250 and the atomizing housing 260, the first guide channel 2512 is indirectly connected to the second air inlet 261 via the second guide channel 3307. This increases the area of ​​the second air inlet 261 and improves air flow.

[0215] Specifically in actual application, when the user inhales the aerosol generating device 400, the external air first enters from the third air inlet 3308 of the bottom cover 330, and then passes through the third mounting groove 3309, the air outlet 3310, the gap between the power supply component 410 and the inner wall of the device shell 420, the first air inlet 2511 of the base 250 into the second air flow channel, and then enters the first aerosol channel 221 and the second aerosol channel through the first air flow channel 211, and finally enters the suction channel 351 to be sucked out.

[0216] Second embodiment

[0217] The aerosol generating device 400 includes the atomizer 300 of the second embodiment and a power supply assembly 410 . The power supply assembly 410 can provide working power for the heating element 20 .

[0218] In this embodiment, the atomizer 300 is detachably connected to the power supply assembly 410. In this way, the atomizer 300 can be replaced to meet the needs of aerosols with different flavors, thereby improving the customer experience.

[0219] The other structures of the aerosol generating device 400 in this embodiment are the same as those in the first embodiment and will not be described again.

[0220] Third embodiment

[0221] Reference Figure 16 , and refer to Figures 19 to 22 , Figure 19 A schematic structural diagram of an aerosol generating device according to a third embodiment of the present application is shown; Figure 20 A schematic diagram showing the structure of a power supply assembly of an aerosol generating device according to a third embodiment of the present application is shown; Figure 21 A schematic structural diagram of the bottom cover of the aerosol generating device according to the third embodiment of the present application is shown; Figure 22 A structural schematic diagram showing another perspective of the bottom cover of the aerosol generating device according to the third embodiment of the present application is shown.

[0222] The aerosol generating device 400 includes the atomizer 300 of the third embodiment and a power supply assembly 410 . The power supply assembly 410 can provide working power for the heating element 20 .

[0223] Furthermore, the power supply assembly 410 is located on one side of at least two atomizer assemblies 200, and is used to provide working power to the atomizer assemblies 200, wherein each atomizer assembly 200 has a positive pin 25 and a negative pin 26, and the power supply assembly 410 has a positive contact and a negative contact. The positive pins 25 of all atomizer assemblies 200 are electrically connected to the positive contact 411, and the power supply assembly 410 and at least two atomizer assemblies 200 can rotate relative to each other so that the negative contact 412 is selectively electrically connected to the negative pin 26 of the corresponding at least one atomizer assembly 200.

[0224] In an embodiment of the present application, the power supply assembly 410 and at least two atomizer assemblies 200 are relatively rotatable, so that the negative contact 412 is selectively electrically connected to the negative electrode pin 26 of a corresponding atomizer assembly 200. In other embodiments, the power supply assembly 410 and at least two atomizer assemblies 200 are relatively rotatable, so that the negative contact 412 is selectively electrically connected to the negative electrode pin 26 of more than two atomizer assemblies 200.

[0225] In this way, by providing the aerosol generating device 400 with a plurality of atomizing assemblies 200 and enabling the power supply assembly 410 to rotate relative to at least two atomizing assemblies 200, when it is necessary to use aerosols of other flavors, it is only necessary to rotate the power supply assembly 410 relative to at least two atomizing assemblies 200 to enable the corresponding at least one atomizing assembly 200 to be electrically connected to the power supply assembly 410 and activated, thereby eliminating the need to clean the oil storage tank and replace the atomizing assembly and oil storage tank with a new one, thereby making it convenient to use aerosols of other flavors. In addition, since the positive pins 25 of all the atomizing assemblies 200 in this application are electrically connected to the positive contact 411, and only the negative pins 26 are electrically connected to the negative contact 412 by rotating and switching, the overall structure is simplified, and the structure of the aerosol generating device 500 is made more compact.

[0226] Specifically, the power supply assembly 410 has a rotation axis that rotates relative to at least two atomizer assemblies 200. The rotation axis passes through the positive contact 411 or the annular area enclosed by the positive contact 411. This prevents the positive contact 411 from separating from the positive lead 25 during relative rotation between the power supply assembly 410 and the at least two atomizer assemblies 200, thereby preventing the electrical connection between the two from being affected.

[0227] In this embodiment, the bottom cover 330 is different from the bottom cover 330 of the aerosol generating device 400 of the second embodiment in that the bottom cover 330 is provided with a fourth air inlet 3311 and a third guide channel 3312 connected to the fourth air inlet 3311. The third guide channel 3312 is connected to the first guide channel 2512 on the base 250 of the atomizer 300, and further connected to the first air inlet 2511.

[0228] In this embodiment, the bottom cover 330 is installed between at least two atomizer assemblies 200 and the power supply assembly 410. The bottom cover 330 has a convergence portion 3313 on the side facing the power supply assembly 410. The convergence portion 3313 is used to converge the positive electrode pins 25 of all the atomizer assemblies 200. The positive electrode contact 411 is electrically connected to the positive electrode pins 25 located in the convergence portion 3313. The provision of the convergence portion 3313 facilitates the convergence of the positive electrode pins 25 of all the atomizer assemblies 200, thereby improving assembly convenience and efficiency.

[0229] Furthermore, the converging portion 3313 includes a converging groove or a converging hole opened on the side of the bottom cover 310 facing the power supply assembly 410. The method of providing the converging groove and the converging hole is simple and reliable.

[0230] In this embodiment, unlike the bottom cover 330 of the aerosol generating device 400 of the second embodiment, the bottom cover 330 is provided with at least two positive electrode pin holes 3301, each positive electrode pin hole 3301 is spaced apart from the convergence portion 3313, and the positive electrode pin 25 of each atomizing assembly 200 is passed through a corresponding positive electrode pin hole 3301 and bent to converge to the convergence portion 3313. By providing the positive electrode pin hole 3301, the path between the positive electrode pin 25 and the convergence portion 3313 can be made, thereby simplifying the assembly process. In other embodiments, each positive electrode pin 25 can also bypass the periphery of the bottom cover 310 to the convergence portion 3313 on the side of the bottom cover 310 facing the power supply assembly 410, which is not limited here.

[0231] Furthermore, at least two first guide portions 3305 are formed on the side of the bottom cover 330 facing the power assembly 410. Each first guide portion 3305 is disposed between a corresponding positive pin hole 3301 and the convergence portion 3313. The first guide portion 3305 is used to guide the corresponding positive pin 25 to the convergence portion 3313. The convergence portion 3313 of this embodiment can be understood as a structure that converges multiple first connection portions 3303 of the second embodiment.

[0232] In this embodiment, at least two negative electrode pin holes 3302 are defined in the bottom cover 330. At least two second connecting portions 3304 are defined on the side of the bottom cover 330 facing the power assembly 410. Each negative electrode pin hole 3302 is spaced apart from the converging portion 3313, and each second connecting portion 3304 is spaced apart from a corresponding negative electrode pin hole 3302. The negative electrode pin 26 of each atomizer assembly 200 passes through a corresponding negative electrode pin hole 3302 and is bent to a corresponding second connecting portion 3304. By bending the positive electrode pin 25 and the negative electrode pin 26 to connect with the first connecting portion 3103 and the second connecting portion 3304, the positive electrode pin 25 and the negative electrode pin 26 are fixed relative to the bottom cover 330, thereby improving the reliability of the connection between the positive electrode pin 25 and the negative electrode pin 26 and the power assembly 410.

[0233] Furthermore, at least two second guide portions 3306 are provided on the side of the bottom cover 330 facing the power assembly 410. Each second guide portion 3306 is provided between a corresponding negative pin hole 3302 and a corresponding second connecting portion 3304. The second guide portion 3306 is used to guide the corresponding negative pin 26 to the corresponding second connecting portion 3304. This ensures that the positive pin 25 and the negative pin 26 can be correctly guided to connect with the first connecting portion 3303 and the second connecting portion 3303, respectively, simplifying the assembly process and improving assembly efficiency.

[0234] In this embodiment, the difference from the aerosol generating device 400 of the second embodiment is that the power supply housing 413 has a docking groove 4131 on the side facing the atomizing housing 260, and a portion of the atomizing housing 260 extends into the docking groove 4131, so that at least two atomizing assemblies 200 are connected to the power supply assembly 410. In this way, by setting a portion of the atomizing housing 260 to extend into the docking groove 4131, the rotation between the two can be limited in a direction perpendicular to the rotation axis, thereby ensuring stable rotation so that the atomizing assembly 200 can be switched accurately. Preferably, the inner profile shape of the docking groove 4131 matches the outer profile shape of the power supply housing 413.

[0235] In this embodiment, the aerosol generating device 400 further includes a first magnetic member 440 and a second magnetic member 450. The first magnetic member 440 is located at one end of the at least two atomizer assemblies 200 facing the power supply assembly 410, and the second magnetic member 450 is located at one end of the power supply assembly 410 facing the two atomizer assemblies 200. The first magnetic member 440 and the second magnetic member 450 can be mutually attracted to each other to position the at least two atomizer assemblies 200 relative to the power supply assembly 410. In this way, the first magnetic member 440 and the second magnetic member 450 can position the at least two atomizer assemblies 200 relative to the power supply assembly 410 without affecting the relative rotation between the two.

[0236] Specifically, the first magnetic member 440 is disposed on the side of the bottom cover 330 facing the power supply assembly 410 . Preferably, a fourth mounting groove 3312 is defined on the side of the bottom cover 330 facing the power supply assembly 410 , and the first magnetic member 440 is mounted in the fourth mounting groove 3312 .

[0237] The second magnetic member 450 is disposed on a side of the power housing 440 facing at least two atomizer assemblies 200 . Preferably, a fifth mounting slot is defined on a side of the power housing 413 facing at least two atomizer assemblies 200 , and the second magnetic member 450 is mounted in the fifth mounting slot.

[0238] Specifically, at least one of the first magnetic member 440 and the second magnetic member 450 comprises a magnet. When both the first magnetic member 440 and the second magnetic member 450 comprise magnets, the magnetism of the magnet in the first magnetic member 440 and the magnet in the second magnetic member 450 are opposite. When one of the first magnetic member 440 and the second magnetic member 450 comprises a magnet, the other of the first magnetic member 440 and the second magnetic member 450 comprises a metal member.

[0239] In some embodiments, the first magnetic member 440 includes a plurality of members, and the second magnetic member 450 includes a plurality of members. The plurality of first magnetic members 440 are spaced apart along the rotation direction of at least two atomizer assemblies 200, and the plurality of first magnetic members 440 are disposed in a one-to-one correspondence with all of the second magnetic members 450. By providing a plurality of first magnetic members 440 and second magnetic members 450, the positioning stability between the at least two atomizer assemblies 200 and the power supply assembly 410 can be improved.

[0240] In other embodiments, there are multiple first magnetic members 440 and one second magnetic member 450, and the multiple first magnetic members 440 are spaced apart along the rotation direction of at least two atomizer assemblies 200, and the second magnetic members 450 can be attracted to each other with a corresponding first magnetic member 450. In other embodiments, there can also be one first magnetic member 440 and multiple second magnetic members 450, which is not limited here.

[0241] In the embodiment of the present application, the atomizer assembly 200 includes two, and the first magnetic members 440 and the second magnetic members 450 each include two, and the two first magnetic members 440 form a 180-degree angle relative to the rotation axis. It is understood that the number of first magnetic members 440 and second magnetic members 450 can be adjusted accordingly based on the number of atomizer assemblies 200.

[0242] The other structures of the aerosol generating device 400 in this embodiment are the same as those in the second embodiment and will not be described again.
