[0100] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements are only drawn by way of example in the drawings and not necessarily 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 Shows Figure 1 The exploded structural diagram of the shown heating component. For ease of description, the drawings only show the structures related to the embodiments of the present application.

[0102] Refer to the attached Figure 1, an embodiment of the present application provides a heating component 100, which includes an oil guiding member 10 and a heating member 20, and the heating member 20 is in contact with the oil guiding member 10. The heating component 100 of the present application is applied to an aerosol generating device 400, specifically, it can be applied to the atomizer 300 of the aerosol generating device 400. In other embodiments, it can also be applied to other devices suitable for the heating component 100, which is not limited herein.

[0103] Specifically in the embodiment of the present application, the oil guiding member 10 may include oil guiding cotton, or may include other porous structures with adsorption ability, which is not limited herein. The shape of the oil guiding member 10 is long strip-shaped, specifically, it can be rectangular.

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

[0105] Through the contact between the heating member 20 and the oil guiding member 10, an atomization surface is formed. Then, when the heating member 20 is working by heating, the atomization liquid from the oil guiding member 10 is atomized to form an aerosol.

[0106] Furthermore, the heating component 100 further includes a base 30. The base 30 has a receiving groove 31. At least a part of the oil guiding member 10 is disposed in the receiving groove 31. The heating member 20 is detachable relative to the base 30 and is clamped and positioned between the oil guiding member 10 and the groove wall of the receiving groove 31 along a first direction, so that one side of the heating member 20 is in contact with the oil guiding member 10. Specifically, the first direction is Figure 2 the X direction shown, specifically, it can be the thickness direction of the oil guiding member 10.

[0107] In actual installation, the heating member 20 can be first placed in the receiving groove 31, and then the oil guiding member 10 is installed in the receiving groove 31 and located between the heating member 20 and the groove wall of the receiving groove 31, so that one side of the oil guiding member 10 can be closely attached to the heating member 20 to form an atomization surface, while the other side of the oil guiding member 10 is restricted by the groove wall of the receiving groove 31. Therefore, the heating member 20 can be fixed on the base 30 by squeezing the heating member 20.

[0108] In this way, a ceramic heating body can be not used. Therefore, the manufacturing process is simplified, and the heating member 20 is positioned between the oil guiding member 10 and the base 30 by a clamping method, without the need to use a winding method, so that the volume of the oil guiding member 10 is not further increased, and the heating member 20 will not be deformed, and it is also convenient for assembly.

[0109] In order to enable the atomized aerosol to be smoothly discharged from the heating component 100, in the embodiments of the present application, the base 30 further has a first aerosol outlet 32 communicating with the accommodation 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 opposite to the oil guiding element 10. That is to say, the first aerosol outlet 32 is disposed opposite to the atomization surface. In this way, the atomized aerosol can reach the first aerosol outlet 32 quickly.

[0111] Furthermore, a plurality of smoke guiding through holes are formed in the heating element 20, and the smoke guiding through holes communicate the first aerosol outlet 32 with the oil guiding element 10. In this way, the atomized aerosol can be guided to the first aerosol outlet 32 through the plurality of smoke guiding through holes and discharged smoothly.

[0112] In some embodiments, the heating element 20 is in a grid shape. Among them, the plurality of smoke guiding through holes are the grid holes on the grid-shaped heating element 20. The grid-shaped heating element 20 can not only make the heating uniform, but also enable the atomized aerosol to be discharged quickly and evenly.

[0113] In some embodiments, the base 30 includes a first side body 33, the accommodation groove 31 is formed on one side of the first side body 33, and the heating element 20 is clamped and positioned between the oil guiding element 10 and the first side body 33 along the first direction. By arranging the cooperation between the first side body 33 and the oil guiding element 10 to clamp and position the heating element 20, the method is simple.

[0114] Furthermore, the first aerosol outlet 32 is formed on the first side body 33. Since the first side body 33 can be directly attached to the heating element 20, therefore, by arranging the first aerosol outlet 32 on the first side body 33, the aerosol can be smoothly discharged from the first aerosol outlet 32, and the structure of the base 30 is also made more compact.

[0115] In some embodiments, the base 30 further includes a second side body 34, the second side body 34 is opposite to and spaced from the first side body 33 along the first direction, and an accommodation groove 31 is formed between the first side body 33 and the second side body 34. By arranging the separated first side body 33 and second side body 34, it is more beneficial to place the oil guiding element 10 in the accommodation groove 31.

[0116] Furthermore, the second side body 34 is provided with a second aerosol outlet 341 communicating with the accommodation groove 31, and the heating element 20 at least partially covers the second aerosol outlet 341. In this way, the 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, and 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, wherein the first direction intersects with the second direction. Specifically, the first direction is perpendicular to the second direction, and the second direction is Figure 2 The Y direction shown may be specifically the length direction of the oil guide member 10. In this way, on the one hand, it is convenient to place the oil guide member 10, and on the other hand, it is possible to make the oil guide member 10 fully contact with the oil to improve the oil guiding effect. In other embodiments, between the first side body 33 and the second side body 34, one side of the receiving groove 31 along the second direction may also define one of the first opening 35 and the second opening 36, and 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 pillars 331 opposite to each other and spaced apart along the second direction, and a first aerosol outlet 32 is formed between each two adjacent side pillars 331. By providing a plurality of side pillars 331, the method of defining the first aerosol outlet 32 is simple, and the side body can have a certain elasticity, and can produce elastic deformation when clamping the heating element 20, thereby better clamping the heating element 20 and improving the 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 holding the heating element 20. By recessing the first side body 33, not only the first aerosol outlet 32 can be formed, but also a channel connected to the first aerosol outlet 32 can be formed, so that the aerosol after atomization can be discharged in a centralized manner.

[0120] In some embodiments, the portion of the second side body 34 that is in contact with the oil guide member 10 covers the heating element 20 along the first direction toward the projection area of the heating element 20. In this way, due to the blocking effect of the second side body 34, the atomized aerosol can only be discharged from the first aerosol outlet 32, thereby preventing the atomized aerosol from leaking and affecting the suction effect.

[0121] In some embodiments, the heating member 20 includes two heating bodies 21. The two heating bodies 21 are opposite and spaced apart along a first direction. One of the heating bodies 21 is clamped between the oil guiding member 10 and the first side body 33 along the first direction, and the other heating body 21 is clamped between the oil guiding member 10 and the second side body 34 along the first direction. The oil guiding member 10 is clamped between the two heating bodies 21. By arranging a plurality of heating bodies 21 in contact with the oil guiding member 10, the atomization area can be increased.

[0122] Furthermore, the heating member 20 further includes an intermediate connecting member 22. The intermediate connecting member 22 connects the two heating bodies 21. A heating groove 23 is formed by enclosing between the intermediate connecting member 22 and the two heating bodies 21. At least a part of the oil guiding member 10 is disposed in the heating groove 23. By providing the intermediate connecting member 22, two heating members 20 can be integrated, improving the installation efficiency. And due to the arrangement of the intermediate connecting member 22, the contact area between the heating member 20 and the oil guiding member 10 can be further increased, thereby increasing the atomization area.

[0123] In some embodiments, the base 30 further includes a base 37. 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. 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 member 20 and the oil guiding member 10 can be supported so that they are stably disposed on the base 30. Further, the intermediate connecting member 22 is connected to the same side of the heating body 21 and is limited between the oil guiding member 10 and the base 37. By limiting the intermediate connecting member 22 between the oil guiding member 10 and the base 37, the positioning stability of the heating member 20 on the base 30 can be further improved, and it is also beneficial to simplify the assembly process.

[0124] Specifically, there are a plurality of intermediate connecting members 22, and the plurality of intermediate connecting members 22 are spaced apart along a second direction. Preferably, the intermediate connecting member 22 includes two. In this way, the connection reliability between the two heating bodies 21 can be improved. And when the intermediate connecting member 22 is limited between the oil guiding member 10 and the base 37, since the contact area between the intermediate connecting member 22 and the oil guiding member 10 and the base 37 is increased, the limiting is more reliable. More specifically, the intermediate connecting member 22 is strip-shaped.

[0125] Furthermore, a heating body 21 can also be provided between two adjacent intermediate connecting members 22. In this way, the contact area between the heating member 20 and the oil guiding 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 at least a part of the heating member 20 covers the third aerosol outlet. In this way, the emission efficiency of the aerosol after atomization can be further improved.

[0127] In some embodiments, the portion of the heating element 20 in contact with the oil guiding element 10 is sheet-shaped. The sheet-shaped heating element 20 can increase the contact area with the oil guiding element 10 compared with the traditional spiral heating element 20, and can make the contact between the heating element 20 and the oil guiding element 10 more stable. Specifically, both heating bodies 21 are sheet-shaped.

[0128] Refer to Figure 3 and Figure 4 , in some embodiments, the base 30 has a positioning portion 38, and the heating element 20 has a mating portion 24. The mating 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 guiding element 10 and the base 30, a positioning portion 38 can be added to the base 30 to pre-position the heating element 20 before being clamped and positioned between the oil guiding element 10 and the base 30, so as to improve the installation stability of the heating element 20.

[0129] Please continue to refer to Figure 4 , specifically, one of the positioning portion 38 and the mating portion 24 includes a positioning groove, and the other includes a positioning protrusion that cooperates with the positioning groove. The way of positioning by the cooperation of the positioning groove and the positioning protrusion is simple and reliable, and is beneficial to assembly.

[0130] In some embodiments, the positioning portion 38 includes at least two, and the at least two positioning portions 38 are arranged at intervals in sequence along the second direction. The mating portion 24 also includes at least two, and all the positioning portions 38 and all the mating portions 24 are arranged in one-to-one correspondence. Setting a plurality of positioning portions 38 and mating portions 24 can improve the reliability of positioning. In the embodiment of the present application, the positioning portion 38 is provided on the side body, and specifically can be provided on the side column 331.

[0131] Please continue to refer to Figure 3 , further, the distance between two of all 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 can be formed, and after cooperating with the mating portion 24, the heating element 20 can be fastened to the base 30.

[0132] In the embodiment of the present application, the positioning portion 38 includes two, and the two positioning portions 38 are arranged at intervals along the second direction at both ends of the heating element 20.

[0133] Please continue to refer to Figure 3 and Figure 4, in some embodiments, the heating element 20 includes a positive electrode pin 25 and a negative electrode pin 26 connected to the heating body 21, and both the positive electrode pin 25 and the negative electrode pin 26 have a mating portion 24. In this way, by using the existing positive electrode pin 25 and negative electrode pin 26 as the structure that mates with the positioning portion 38 of the base 30, the structure of the heating element 20 can be simplified. Moreover, usually both the positive electrode pin 25 and the negative electrode pin 26 need to extend outwards from the heating assembly 100. Therefore, the contact length between them and the positioning portion 38 can be increased, thereby improving the positioning reliability.

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

[0135] Referring to Figures 6 - 10 , Figure 6 shows a schematic structural view of the atomization assembly according to the first embodiment of the present application; Figure 7 shows an exploded structural view of the atomization assembly according to the first embodiment of the present application; Figure 8 shows a schematic structural view of a part of the atomization assembly according to the first embodiment of the present application; Figure 9 shows a schematic structural view of the support member of the atomization assembly according to the first embodiment of the present application; Figure 10 shows a schematic structural view of a part of the atomization assembly according to the first embodiment of the present application.

[0136] The atomization assembly 200 includes the heating assembly 100 and the support member 210 in any of the above embodiments. The support member 210 has a first air flow channel 211, and the heating element 20 and at least part of the oil guiding member 10 are located in the first air flow channel 211.

[0137] In this way, the aerosol atomized by the heating element 20 can enter the first air flow channel 211 and then be sucked by the user.

[0138] It can be understood that the first air flow channel 211 of the present application is in communication with the external air.

[0139] Please continue to refer to Figure 8 and Figure 9 , further, the base 30 is installed on the support member 210, at least part of the heating element 20 is exposed outside the base 30, and the receiving groove 31 is in communication with the first air flow channel 211. Specifically, the base 30 is detachably installed on the support member 210.

[0140] In this way, the heating assembly 100 can be integrally installed on the support member 210, simplifying the installation process, and the atomized aerosol can also smoothly enter the first air flow channel 211 of the support member 210.

[0141] Specifically, in the embodiment of the present application, the heating element 20 is exposed on one side of the oil guiding member 10 in the first direction and is spaced from the inner wall of the first air flow channel 211 to form an atomization channel. Specifically, the heating element 20 is exposed on 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. In this way, the heating element 20 can be directly communicated with the first air flow channel 211, so that the atomized aerosol can quickly enter the first air flow channel, thereby improving the emission efficiency of the atomized aerosol and avoiding leakage.

[0142] In this embodiment, the first air flow channel 211 extends in the third direction, and the third direction intersects the first direction. Optionally, the third direction is perpendicular to the first direction, that is, it can be understood that the atomization surface is parallel to the first air flow channel 211. Specifically, the third direction is Figure 2 the Z direction shown in the figure, specifically, it can be the height direction of the oil guiding 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.

[0143] In this embodiment, the support member 210 is provided with a communication hole 212 communicating with the first air flow channel 211, and a part of the oil guiding member 10 extends out of the support member 210 from the communication hole 212. By arranging a part of the oil guiding member 10 to extend out of the support member 210, the oil guiding member 10 can be fully contacted with the oil liquid to improve the oil guiding effect. Specifically, the support member 210 is provided with a communication hole 212 communicating with the first air flow channel 211 in the second direction. Since the extending direction of the oil guiding member 10 is the second direction intersecting the first direction, it does not affect the clamping of the heating element 20 by the oil guiding member 10 in the first direction, and the atomized aerosol is not easily leaked from the communication hole 212.

[0144] Preferably, the support member 210 is provided with a plurality of communication holes 212, and all the communication holes 212 are arranged at intervals along the circumferential direction of the support member 210. A plurality of parts of the oil guiding member 10 respectively extend out of the support member 210 from the plurality of communication holes 212. In this way, the oil guiding range can be expanded and the oil guiding efficiency can be improved. Preferably, the support member 210 includes two communication holes 212 oppositely arranged in the second direction, and both ends of the oil guiding member 10 respectively extend out of the support member 210 from the two communication holes 212.

[0145] Furthermore, part of the base 30 protrudes from the connecting hole 212 to the outside of the support member 210 to be supported on the hole wall of the connecting hole 212. In this way, the assembly process of the base 30 relative to the support member 210 is simplified. Specifically, the base 37 of the base 30 protrudes from the side body along the second direction and penetrates the connecting hole 212, and is supported on the hole wall of the connecting hole 212 along the third direction. Furthermore, part of the oil guide member 10 is supported on the part of the base 30 protruding from the outside of the support member 210. In this way, on the one hand, due to the lengthening of the base 37, the support area of the oil guide member 10 is increased, and on the other hand, the cooperation between the base 37 and the connecting hole 212 can also reliably position the base 30, thereby improving the installation reliability of the base 30 relative to the support member 210.

[0146] 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 airflow channel 211, wherein the oil guide member 10 is limited between the first connecting member 220 and the support member 210.

[0147] Thus, by setting the oil guide member 10 to be limited between the first connecting member 220 and the supporting member 210, the oil guide member 10 can be fully compressed so that the oil guide member 10 is not easy to loosen, and then maintains close contact with the heating element 20, thereby improving the atomization effect. In addition, the oil guide member 10 also has a first aerosol channel 221 for circulating the atomized aerosol, so it integrates multiple functions, thereby simplifying the structure of the atomization assembly 200.

[0148] Furthermore, when part of the oil guide member 10 extends out of the outer side of the support member 210 from the connecting hole 212, the first connecting member 220 is sleeved on the outer side of the support member 210 to limit the oil guide member 10 on the outer side of the support member 210. By setting the first connecting member to limit the oil guide member 10 on the outer side of the support member 210, on the one hand, the first aerosol channel 221 can be expanded, and on the other hand, the installation process is also simple, and it can be observed at the same time whether the installation between the oil guide member 10 and the first connecting member 220 is in place, thereby improving the installation reliability of the oil guide member 10.

[0149] Specifically, the first connecting member 220 is tubular, and the supporting member 210 is also tubular.

[0150] 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 can be prevented from leaking from the communicating hole 212 and affecting the suction effect.

[0151] 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.

[0152] In this embodiment, when a part of the oil guide member 10 is supported on the part of the base 30 protruding from the support member 210, since the base 30 can provide a larger support area, the oil guide member 10 can be reliably defined between the first connecting member 220 and the base 30, further improving the installation reliability of the oil guide member 10.

[0153] In this embodiment, the first connecting member 220 includes 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 with the support member 210, thereby preventing the atomized aerosol from leaking between the two.

[0154] In this embodiment, the atomization assembly 200 further includes an oil storage member 230 which is arranged outside the support member 210 and the first connecting member 220 and is in contact with the oil guide member 10. Specifically, the oil storage member 230 covers the outside of the support member 210 and the first connecting member 220.

[0155] Furthermore, the oil storage member 230 includes at least two sub-oil storage members 231 which can be joined together to form a first accommodation space for accommodating the support member 210 and the first connecting member 220. The first accommodation space can be in the form of a through hole. By providing a plurality of spliced sub-oil storage members 231, the installation of the oil storage member 230 can be more convenient. Specifically, at least two sub-oil storage members 231 are circumferentially distributed along 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, and a placement groove or a placement hole for accommodating the support member 210 and the first connecting member 220 is provided at one end of the oil storage member 230.

[0156] Furthermore, there is an oil absorption gap between at least two adjacent sub-oil storage members 231. In this way, the aerosol leaked accidentally can be adsorbed.

[0157] Preferably, the oil storage member 230 includes two sub-oil storage members 231 joined together in the first direction.

[0158] In this embodiment, at least a part of the oil guide member 10 protruding from the support member 210 can be clamped between at least two adjacent sub-oil storage members 231. In this way, the oil guide member 10 can be fixed relative to the oil storage member 230 through this clamping action, thereby improving the effect of guiding the aerosol. Specifically, a clamping hole is provided on at least one sub-oil storage member 231, and at least a part of the oil guide member 10 protruding from the support member 210 is clamped in the clamping hole. Preferably, at least a part of each oil guide member 10 protruding from the support member 210 is clamped by two adjacent sub-oil storage members 231.

[0159] In this embodiment, the sub-oil storage member 231 includes a porous oil storage member such as oil storage cotton.

[0160] In this embodiment, the atomization assembly 200 further includes a sealing seat 240 and a base 250. The sealing seat 240 is connected to one end of the first connecting member 220 away from the support member 210, and the base 250 is connected to one end of the support member 210 away from the first connecting member 220. A limiting space is formed between the sealing seat 240 and the base 250, and the oil storage member 230 is limited within the limiting space. By providing the sealing seat 240 and the base 250, a limiting space for limiting the oil storage member 230 is formed, so that the position of the oil storage member 230 relative to the oil guiding member 10 is more reliable, enabling the aerosol to be smoothly guided.

[0161] Furthermore, the sealing seat 240 includes a sealing seat body 241 and a second connecting member 242. The second connecting member 242 is disposed on the side of the sealing seat body 241 facing the first connecting member 220, and 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.

[0162] Specifically, the second connecting member 242 can be sleeved outside the first connecting member 220. In other embodiments, the second connecting member 242 can be sleeved inside the first connecting member 220, which is not limited herein. More specifically, the second connecting member 242 is tubular, and an interference fit exists between the second connecting member 242 and the first connecting member 220.

[0163] It should be noted that the sealing seat 240 further has a second aerosol channel, and the second aerosol channel is communicated with the first aerosol channel 221. Specifically, the second aerosol channel penetrates through the sealing seat body 241 and the second connecting member 242.

[0164] 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 the side of the base body 251 facing the support member 210, and the third connecting member 252 can be sleeved with the support member 210.

[0165] Specifically, the third connecting member 252 can be sleeved outside the support member 210. In other embodiments, the third connecting member 252 can be sleeved inside the support member 210, which is not limited herein. More specifically, the second connecting member 242 is tubular, and an interference fit exists between the third connecting member 252 and the support member 210.

[0166] It should be noted that the base 250 further has a second air flow channel, and the second air flow channel is communicated with the first air flow channel 211. Specifically, the second air flow channel penetrates through the base body 251 and the third connecting member 252.

[0167] Please continue to refer to Figure 10, Further, a first air inlet 2511 and a first guiding channel 2512 communicating with the second air flow channel are formed on the base 250. The first air inlet 2511 communicates with one end of the second air flow channel far from the support member 210. The first guiding channel 2512 communicates with the first air inlet 2511, and the extending direction of the first guiding channel 2512 intersects with the axial direction of the first air inlet 2511. Specifically, the extending direction of the first guiding channel 2512 is parallel to the second direction, and the axial direction of the first air inlet 2511 is parallel to the third direction.

[0168] In this embodiment, through holes for the positive electrode pin 25 and the negative electrode pin 26 to pass through are formed on the base 250. Preferably, the first air inlet 2511 is a through hole, or the through hole is arranged at an interval from the first air inlet 2511.

[0170] Specifically, the atomization housing 260 has an oil storage chamber 261, and the oil guiding member 10 communicates with the oil storage chamber 261. In this way, the aerosol in the oil storage chamber 261 can be guided to the heating element 20, so that the atomization of the aerosol can proceed smoothly. More specifically, the oil storage member 230 is arranged in the oil storage chamber 261.

[0171] More specifically, the sealing seat 240 and the base 250 are respectively in sealing cooperation with the inner wall of the atomization housing 260 in the circumferential direction, and an oil storage chamber 261 is defined between the sealing seat 240, the base 250 and the atomization housing 260. In this way, under the joint limitation of the sealing seat 240, the base 250 and the atomization housing 260, the oil storage member 230 can be reliably installed in the oil storage chamber 261. Preferably, the atomization housing 260 is tubular.

In this way, air can be introduced from the outside into the first guiding channel 2512 through the second air inlet 262 on the atomization housing 260, and then enter the first air inlet 2511.

[0175] The other structures of the atomization component 200 in this embodiment are the same as those in the first embodiment, and will not be described in detail here.

[0176] The atomization component 200 of this embodiment can be applied to the atomizer 300 described later, and the atomizer 300 can be detachably connected to the power supply component 410 of the aerosol generating device 400.

Among them, the positive connection portion 340 and the negative connection portion 350 can be electrically connected to the positive contact 411 and the negative contact 412 of the external power supply assembly 410. The power supply assembly 410 can provide working power to the heating element 20. In this way, the method of setting the positive connection portion 340 to be electrically connected to the positive pin 25 in the first connection groove or the first connection hole is simple and reliable, and the method of setting the negative connection portion 350 to be electrically connected to the negative pin 26 in the second connection groove or the second connection hole is simple and reliable.

[0190] Further, a first guiding portion 3305 is provided on the side of the bottom cover 330 facing away from the base 250. The first guiding portion 3305 is disposed between the positive electrode pin hole 3301 and the first connecting portion 3303, and the first guiding portion 3305 is used to guide the positive electrode pin 25 to the first connecting portion 3303. In this way, the positive electrode pin 25 can be correctly guided to be connected to the first connecting portion 3303, simplifying the assembly process and improving the assembly efficiency. Preferably, the first guiding portion 3305 includes a first guiding groove formed on the side of the bottom cover 330 facing away from the base 250. More preferably, the first guiding groove communicates with the positive electrode pin hole 3301 and the first connecting groove. In this way, the positive electrode pin 25 is restricted by the groove wall of the first guiding groove and can be correctly guided to the first connecting portion 3303. In addition, since the positive electrode pin 25 is located in the first guiding groove, it can be protected to avoid being damaged.

In order to avoid the first guiding channel 2512 being opened too deep, which affects the sealing fit between the base 250 and the atomizing housing 260, therefore, by indirectly connecting the first guiding channel 2512 with the second air inlet 262 through the second guiding channel 3307, the area of the second air inlet 262 can be increased, improving the air intake smoothness.

[0193] The other structures of the atomizer 300 in this embodiment are the same as those in the first embodiment and will not be described in detail here.

[0203] Based on the same inventive concept, the present application also provides an aerosol generating device 400. Embodiment

[0204] Refer to Figure 17 and Figure 18 , which shows an exploded structural schematic diagram of the aerosol generating device according to the first embodiment of the present application;Figure 18 The structural schematic diagram of the bottom cover of the aerosol generating device according to the first embodiment of the present application is shown.

[0205] The aerosol generating device 400 includes the atomizer 300 of the above-mentioned first embodiment and a power supply assembly 410, and the power supply assembly 410 can provide a working power supply for the heating element 20.

[0206] In this embodiment, the atomizer 300 and the power supply assembly 410 are integrally provided. Specifically, the aerosol generating device 400 includes a device housing 420, the power supply assembly 410 includes a power supply housing 413 (shown in the second embodiment), and the atomization housing 260 and the power supply housing 413 are integrally formed to form the device housing 420.

[0207] Furthermore, first openings 263 and fifth openings 421 communicating with the interior thereof are formed at both ends of the device housing 420. The mouthpiece 310 is installed at the first opening 263. The aerosol generating device 400 further includes a bottom cover 330. Different from the bottom cover 330 of the atomizer 300 in the above-mentioned second and third embodiments, the bottom cover 330 of this embodiment is installed at the fifth opening 421. A second accommodation space for the power supply 414 of the power supply assembly 410 is defined between the bottom cover 330, the base 250 and the device housing 420.

[0208] Still further, the bottom cover 330 is provided with a third air inlet hole 3308, a third installation groove 3309 and an air outlet hole 3310.

[0209] Specifically in practical applications, when the user sucks the aerosol generating device 400, external air first enters from the third air inlet hole 3308 of the bottom cover 330, sequentially passes through the third installation groove 3309, the air outlet hole 3310, the gap between the power supply assembly 410 and the inner wall of the device housing 420, the first air inlet 2511 of the base 250 and enters the second air flow channel, and then enters the first air flow channel 211, the first aerosol channel 221, the second aerosol channel, and finally enters the suction channel 311 and is sucked out. Embodiment

[0210] The aerosol generating device 400 includes the atomizer 300 of the above-mentioned second embodiment and a power supply assembly 410, and the power supply assembly 410 can provide a working power supply for the heating element 20.

[0211] 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 different flavors of aerosol, thereby enhancing the customer experience.

[0212] 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 herein again. Embodiment

[0213] Referring to Figure 16 and simultaneously referring to Figures 19 - 22 , Figure 19 shows a schematic structural view of the aerosol generating device according to the third embodiment of the present application; Figure 20 shows a schematic structural view of the power supply assembly of the aerosol generating device according to the third embodiment of the present application; Figure 21 shows a schematic structural view of the bottom cover of the aerosol generating device according to the third embodiment of the present application; Figure 22 shows a schematic structural view of the bottom cover of the aerosol generating device according to the third embodiment of the present application from another perspective.

[0214] The aerosol generating device 400 includes the atomizer 300 and the power supply assembly 410 of the above third embodiment, and the power supply assembly 410 can provide a working power supply for the heating element 20.

[0215] Further, the power supply assembly 410 is located on one side of at least two atomization assemblies 200 for providing a working power supply to the atomization assemblies 200. Each atomization 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 the atomization assemblies 200 are electrically connected to the positive contact 411, and the power supply assembly 410 and at least two atomization 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 atomization assembly 200.

[0216] In the embodiment of the present application, the power supply assembly 410 and at least two atomization 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 one atomization assembly 200. In other embodiments, the power supply assembly 410 and at least two atomization assemblies 200 can rotate relative to each other so that the negative contact 412 is selectively electrically connected to the negative pins 26 of the corresponding two or more atomization assemblies 200.

[0217] Thus, by providing that the aerosol generating device 400 includes a plurality of atomization components 200 and enabling relative rotation between the power supply component 410 and at least two atomization components 200, when it is necessary to use aerosols of other flavors, it is only necessary to relatively rotate the power supply component 410 and at least two atomization components 200, so that the corresponding at least one atomization component 200 is electrically connected to the power supply component 410 and enabled. Thus, there is no need to clean the oil storage chamber and replace the new atomization component and oil storage chamber, so it becomes convenient to use aerosols of other flavors. In addition, since the positive electrode pins 25 of all the atomization components 200 in the present application are electrically connected to the positive electrode contacts 411, and only the negative electrode pins 26 are rotated and switched to be electrically connected to the negative electrode contacts 412, the overall structure is simplified, and the structure of the aerosol generating device 500 is made more compact.

[0218] Specifically, the power supply component 410 has a rotation axis that rotates relative to at least two atomization components 200, and the rotation axis passes through the positive electrode contact 411 or passes through the annular region enclosed by the positive electrode contact 411. Thus, during the relative rotation between the power supply component 410 and at least two atomization components 200, the separation between the positive electrode contact 411 and the positive electrode pin 25 can be avoided, which affects the electrical connection between the two.

[0219] In this embodiment, the difference between the bottom cover 330 and the bottom cover 330 of the aerosol generating device 400 in the second embodiment is that the bottom cover 330 is provided with a fourth air inlet 3311 and a third guiding channel 3312 communicating with the fourth air inlet 3311. The third guiding channel 3312 communicates with the first guiding channel 2512 on the base 250 of the atomizer 300, and further communicates with the first air inlet 2511.

[0220] In this embodiment, the bottom cover 330 is installed between at least two atomization components 200 and the power supply component 410. One side of the bottom cover 330 facing the power supply component 410 has a converging portion 3313 for converging the positive electrode pins 25 of all the atomization components 200. The positive electrode contact 411 is electrically connected to the positive electrode pins 25 located in the converging portion 3313. By providing the converging portion 3313, it is more beneficial to converge the positive electrode pins 25 of all the atomization components 200, so as to improve the assembly convenience and assembly efficiency.

[0221] Furthermore, the converging portion 3313 includes a converging groove or a converging hole formed on one side of the bottom cover 330 facing the power supply component 410. The method of providing the converging groove and the converging hole is simple and reliable.

[0222] In this embodiment, different from the bottom cover 330 of the atomizer 300 of the aerosol generating device 400 in the second embodiment, at least two positive electrode pin holes 3301 are formed in the bottom cover 330. Each positive electrode pin hole 3301 is spaced from the converging portion 3313. The positive electrode pin 25 of each atomization component 200 passes through a corresponding positive electrode pin hole 3301 and is bent and converged to the converging portion 3313. By forming the positive electrode pin holes 3301, the path between the positive electrode pin 25 and the converging 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 330 to the converging portion 3313 on the side of the bottom cover 330 facing the power supply component 410, which is not limited herein.

[0223] Further, at least two first guiding portions 3305 are formed on the side of the bottom cover 330 facing the power supply component 410. Each first guiding portion 3305 is disposed between a corresponding positive electrode pin hole 3301 and the converging portion 3313. The first guiding portion 3305 is used to guide the corresponding positive electrode pin 25 to the converging portion 3313. The converging portion 3313 in this embodiment can be understood as a structure that converges a plurality of first connecting portions 3303 in the second embodiment.

[0224] In this embodiment, at least two negative electrode pin holes 3302 are formed in the bottom cover 330. At least two second connecting portions 3304 are provided on the side of the bottom cover 330 facing the power supply component 410. Each negative electrode pin hole 3302 is spaced from the converging portion 3313. Each second connecting portion 3304 is spaced from a corresponding negative electrode pin hole 3302. The negative electrode pin 26 of each atomization component 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 be connected to the first connecting portion 3303 and the second connecting portion 3304, the positions of the positive electrode pin 25 and the negative electrode pin 26 relative to the bottom cover 330 can be fixed, thereby improving the connection reliability between the positive electrode pin 25 and the negative electrode pin 26 and the power supply component 410.

[0225] Further, at least two second guiding portions 3306 are provided on the side of the bottom cover 330 facing the power supply component 410. Each second guiding portion 3306 is disposed between a corresponding negative electrode pin hole 3302 and a corresponding second connecting portion 3304. The second guiding portion 3306 is used to guide the corresponding negative electrode pin 26 to the corresponding second connecting portion 3304. In this way, the positive electrode pin 25 and the negative electrode pin 26 can be respectively correctly guided to be connected to the first connecting portion 3303 and the second connecting portion 3304, simplifying the assembly process and improving the assembly efficiency.

[0226] In this embodiment, different from the aerosol generating device 400 of the second embodiment, a docking groove 4131 is provided on one side of the power supply housing 413 facing the atomizing housing 260, and a part 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 part 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 and accurate switching of the atomizing assembly 200. Preferably, the inner profile shape of the docking groove 4131 matches the outer profile shape of the power supply housing 413.

[0227] In this embodiment, the aerosol generating device 400 further includes a first magnetic attracting member 440 and a second magnetic attracting member 450. The first magnetic attracting member 440 is located at one end of at least two atomizing assemblies 200 facing the power supply assembly 410, and the second magnetic attracting member 450 is located at one end of the power supply assembly 410 facing the two atomizing assemblies 200. The first magnetic attracting member 440 can attract the second magnetic attracting member 450 to position at least two atomizing assemblies 200 relative to the power supply assembly 410. In this way, the first magnetic attracting member 440 and the second magnetic attracting member 450 can position at least two atomizing assemblies 200 relative to the power supply assembly 410 without affecting the relative rotation between the two.

[0228] Specifically, the first magnetic attracting member 440 is provided on one side of the bottom cover 330 facing the power supply assembly 410. Preferably, a fourth installation groove 3314 is provided on one side of the bottom cover 330 facing the power supply assembly 410, and the first magnetic attracting member 440 is installed in the fourth installation groove 3314.

[0229] The second magnetic attracting member 450 is provided on one side of the power supply housing 413 facing at least two atomizing assemblies 200. Preferably, a fifth installation groove is provided on one side of the power supply housing 413 facing at least two atomizing assemblies 200, and the second magnetic attracting member 450 is installed in the fifth installation groove.

[0230] Specifically, at least one of the first magnetic attracting member 440 and the second magnetic attracting member 450 includes a magnet. When both the first magnetic attracting member 440 and the second magnetic attracting member 450 include magnets, the magnets of the first magnetic attracting member 440 and the second magnetic attracting member 450 have opposite magnetic polarities. When one of the first magnetic attracting member 440 and the second magnetic attracting member 450 includes a magnet, the other of the first magnetic attracting member 440 and the second magnetic attracting member 450 includes a metal member.

[0231] In some embodiments, there are multiple first magnetic members 440 and multiple second magnetic members 450. The multiple first magnetic members 440 are arranged at intervals along the rotation direction of at least two atomizing components 200, and the multiple first magnetic members 440 are arranged in one-to-one correspondence with all the second magnetic members 450. By providing the multiple first magnetic members 440 and the second magnetic members 450, the positioning stability between at least two atomizing components 200 and the power supply component 410 can be improved.

[0232] In some other embodiments, there are multiple first magnetic members 440 and one second magnetic member 450. The multiple first magnetic members 440 are arranged at intervals along the rotation direction of at least two atomizing components 200, and the second magnetic member 450 can be attracted to a corresponding first magnetic member 440. In other embodiments, it may also be that there is one first magnetic member 440 and multiple second magnetic members 450, which is not limited herein.

[0233] In the embodiments of the present application, there are two atomizing components 200, and both the first magnetic member 440 and the second magnetic member 450 include two. Moreover, the angle between the two first magnetic members 440 with respect to the rotation axis is 180 degrees. It can be understood that the number of the first magnetic members 440 and the second magnetic members 450 can be correspondingly adjusted according to the number of the atomizing components 200.

[0234] 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 in detail herein.

[0235] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described.
