[0029] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 1As shown, the aerosol generating device includes a power supply component 1 and an atomizer 2. The power supply component 1 is used to supply power to the atomizer 2.

[0030] Figure 2 This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of this application, as shown below. Figure 2 As shown, the atomizer 2 includes a liquid reservoir 21, an atomizing core assembly 22, and a mouthpiece 23. The liquid reservoir 21 stores the aerosol matrix. The atomizing core assembly 22 is located in the liquid reservoir 21 and is used to heat the aerosol matrix. The atomizing core assembly 22 has an atomization channel 22a. The mouthpiece 23 is connected to one end of the atomization channel 22a.

[0031] The liquid storage assembly 21 may include a liquid storage chamber housing 211 and a sealing base 212. The sealing base 212 may be fixedly connected to the liquid storage chamber housing 211 or detachably connected to it. The liquid storage chamber housing 211 and the sealing base 212 are connected to form a liquid storage chamber 20a, which is used to contain the aerosol matrix. The sealing base 212 may be used to install an electrode 2121, which is used to electrically connect the liquid storage assembly 21 and the power supply assembly 1. The sealing base 212 is also provided with an air inlet 212a. There may be one or multiple air inlets 212a. During suction, outside air can enter the atomizing core assembly 22 through the air inlets 212a.

[0032] In some examples, the liquid storage assembly 21 may also include a liquid storage element, such as a liquid storage cotton that has been adsorbed / wetted with an aerosol matrix.

[0033] The atomizing core assembly 22 is located within the liquid storage chamber housing 211. The atomizing core assembly 22 includes an atomizing core cover 221, a liquid guide 222, a heating element 223, and a lead wire 224. The liquid guide 222 and the heating element 223 are located within the atomizing core cover 221. The lead wire 224 is electrically connected to the heating element 223. The lead wire 224 also extends outside the atomizing core cover 221 and is connected to an electrode 2121.

[0034] The atomizing core cover 221 provides space inside the liquid storage tank shell 211 to accommodate the liquid guiding component 222 and the heating component 223. The atomizing core cover 221 may be cylindrical, and its wall may have structures such as holes and slits to allow the aerosol matrix in the liquid storage tank shell 211 to enter the atomizing core cover 221 and be absorbed by the liquid guiding component 222. The heating component 223 is used to heat the aerosol matrix in the liquid guiding component 222, causing the aerosol matrix to vaporize.

[0035] The material and structure of the heating element 223 are not limited, as long as it can generate heat. For example, the heating element 223 may include at least one of heating mesh, heating film, heating wire, and heating plate.

[0036] The lifespan of the atomizer coil assembly 22 is limited. During continuous heating, it gradually ages, leading to performance degradation. When the performance of the atomizer coil assembly 22 deteriorates to the point where it no longer meets the user's requirements, or when its remaining lifespan is short, the user will typically choose to replace it with a new atomizer 2. The heating effect of the atomizer coil assembly 22 is affected by the heating element 223. When the user desires a different heating effect, such as higher heating power, the user will also need to replace it with a new atomizer 2.

[0037] In these cases, replacing atomizer 2 significantly increases the cost for users of the aerosol generating device. To reduce the cost for users of atomizer 2, embodiments of this application provide an atomization module.

[0038] Figure 3 This is a schematic diagram of the structure of an atomizing module provided in an embodiment of this application, as shown below. Figure 3 As shown, the atomizing module 220 includes an atomizing core assembly 22 and a mounting base 24. The mounting base 24 is connected to one end of the atomizing core assembly 22, and an electrode 2121 is provided on the side of the mounting base 24 away from the atomizing core assembly 22. The electrode 2121 is electrically connected to the atomizing core assembly 22.

[0039] Figure 4 This is an assembly diagram of an atomizing module and a liquid storage component provided in an embodiment of this application, as shown below. Figure 4 As shown, the atomizing module 220 is detachably inserted into the liquid storage assembly 21. The mounting base 24 is detachably inserted into the insertion hole 20b of the sealing base 212 of the liquid storage assembly 21 and is sealed to the insertion hole 20b.

[0040] By assembling the atomizing core assembly 22 and the mounting base 24, an atomizing module 220 is formed for detachable insertion into the liquid storage assembly 21. The mounting base 24 is connected to one end of the atomizing core assembly 22, and an electrode for electrically connecting the atomizing core assembly 22 and the power supply assembly 1 is provided on the side of the mounting base 24 away from the atomizing core assembly 22. When assembling the atomizing module 220 with the liquid storage assembly 21, the atomizing core assembly 22 can be inserted into the liquid storage assembly 21, and the mounting base 24 can be detachably inserted into the sealing base 212 of the liquid storage assembly 21, forming a sealed fit. If the atomizing core assembly 22 cannot meet the user's requirements, the entire atomizing module 220 can be pulled out of the liquid storage assembly 21 through the mounting base 24, and then the atomizing module 220 can be replaced and inserted into the liquid storage assembly 21. Since only the atomization module 220 needs to be replaced, the cost of using an aerosol generator can be greatly reduced.

[0041] In some possible implementations, the structure of the atomizing core assembly 22 can be similar to... Figure 2The atomizing core assembly 22 shown has the same structure.

[0042] Figure 5 This is a schematic diagram of the internal structure of an atomizing module provided in an embodiment of this application, as an example, such as... Figure 5 As shown, the atomizing core assembly 22 may include an atomizing core cover 221, a first liquid guiding element 2221, a tubular support 225, a second liquid guiding element 2222, a heating element 223, and a lead wire 224. The axial length of the second liquid guiding element 2222 may be less than the axial length of the first liquid guiding element 2221. The second liquid guiding element 222 and the heating element 223 are located in the tubular support 225. The tubular support 225 is disposed in the first liquid guiding element 2221, and the first liquid guiding element 2221 is disposed in the atomizing core cover 221. The lead wire 224 is electrically connected to the heating element 223. The lead wire 224 also extends outside the atomizing core cover 221 and is connected to the electrode 2121.

[0043] The tubular stent 225 can be cylindrical, and the tube wall of the tubular stent 225 can have structures such as holes and slits, so that the aerosol matrix in the first liquid guiding element 2221 can enter the tubular stent 225 and be absorbed by the second liquid guiding element 2222.

[0044] Heating element 223 may include one or more heating grids 2231, for example, Figure 7 As shown, the heating element 223 includes two heating meshes 2231, which are arranged at an axial distance along the second liquid guiding element 2222.

[0045] The atomizing core assembly 22 may also include a support ring 226, which may be disposed in the end of the tubular support 225 near the mounting base 24. The support ring 226 can be used to support the tubular support 225 and prevent the tubular support 225 from shrinking or deforming. The lead wire 224 can extend from between the support ring 226 and the tubular support 225.

[0046] The atomizing core assembly 22 may also include a sealing ring 227, which is arranged between the tubular support 225 and the atomizing core cover 221. The sealing ring 227 may be sleeved on the end of the tubular support 225 near the mounting base 24, and the sealing ring 227 is in sealing engagement with both the tubular support 225 and the atomizing core cover 221.

[0047] An annular groove 221a can be formed between the sealing ring 227 and the atomizing core cover 221, which can be used to connect with the mounting base 24.

[0048] like Figure 5As shown, the mounting base 24 includes an atomizer core bracket 241 and an atomizer core base 242. The atomizer core bracket 241 is connected to one end of the atomizer core assembly 22, and the atomizer core base 242 is detachably connected to the side of the atomizer core bracket 241 away from the atomizer core assembly 22. The electrode 2121 is connected to the atomizer core base 242.

[0049] The atomizer coil bracket 241 supports the end of the atomizer coil assembly 22, and the atomizer coil base 242 is used to mount the electrode 2121. By detachably connecting the atomizer coil bracket 241 and the atomizer coil base 242, when the atomization module 220 needs to be replaced, at least the atomizer coil base 242 and the electrode 2121 can be retained, and only the atomizer coil assembly 22 and the atomizer coil bracket 241 need to be replaced, thereby further reducing the cost of using the aerosol generating device.

[0050] For example, the atomizer core base 242 and the atomizer core support 241 can be connected by a snap-fit. The electrode 2121 and the atomizer core base 242 can be integrally molded components.

[0051] A one-piece molded structure refers to a structure in which the atomizer core base 242 and the electrode 2121 are formed as a single unit using a one-piece molding process, and the two are connected as a whole through this process. For example, the one-piece molding process can include an insert molding process. When manufactured using the one-piece molding process, the electrode 2121 can be placed as an insert into the mold used to form the atomizer core base 242.

[0052] In the integrated structure formed by the one-piece molding process, the atomizing core base 242 and the electrode 2121 are tightly connected and not prone to leakage, and the assembly process of the atomizing core base 242 and the electrode 2121 is also eliminated.

[0053] In some examples, the atomizer coil holder 241 and the atomizer coil assembly 22 can also be detachably connected, so that when the atomizer coil assembly 22 needs to be replaced, the atomizer coil holder 241 can be retained and only the atomizer coil assembly 22 needs to be replaced.

[0054] For example, an annular protrusion 2411 may be provided on the side of the atomizer core holder 241 away from the atomizer core base 242, and the annular protrusion 2411 can be inserted into the atomizer core assembly 22. Figure 5 As shown, the annular protrusion 2411 can be inserted into the annular groove 221a between the sealing ring 227 and the atomizing core cover 221.

[0055] like Figure 5 As shown, the atomizer core holder 241 is provided with an electrode slot 241a, in which the electrode 2121 is inserted. One end of the lead wire 224 extends into the electrode slot 241a and contacts the electrode 2121 located in the electrode slot 241a.

[0056] By extending the lead wire 224 into the electrode slot 241a, when assembling the atomizer coil base 242 and the atomizer coil support 241, the electrode 2121 can be inserted into the electrode slot 241a, allowing the electrode 2121 to contact the lead wire 224 and form an electrical connection. When the atomizer coil base 242 is separated from the atomizer coil support 241, and the electrode 2121 is pulled out of the electrode slot 241a, the electrode 2121 can be separated from the lead wire 224, facilitating the assembly and disassembly of the atomizer coil base 242 and the atomizer coil support 241.

[0057] The number of electrodes 2121 can be the same as the number of leads 224, and the electrodes 2121 can be arranged in a one-to-one correspondence with the leads 224.

[0058] For example, three electrodes 2121 and three leads 224 can be provided.

[0059] In some other possible implementations, the number of electrodes 2121 may be less than the number of leads 224, and some leads 224 may be electrically connected to the same electrode 2121.

[0060] For example, there can be two electrodes 2121 and three leads 224. Two of the three leads 224 are electrically connected to the same electrode 2121, and the other lead 224 is electrically connected to another electrode 2121.

[0061] In some examples, a plurality of electrodes 2121 are provided on the side of the mounting base 24 away from the atomizing core assembly 22, and at least some of the plurality of electrodes 2121 are centrally symmetrically distributed.

[0062] For example, in this example, the three electrodes 2121 can be distributed along a line, with the two outer electrodes 2121 being centrally symmetrical about the middle electrode 2121.

[0063] Multiple electrodes 2121 are arranged in a centrally symmetrical manner, so that even if the atomizing module 220 is rotated 180° when assembling the atomizing module 220 and the liquid storage component 21, the multiple electrodes 2121 can still be electrically connected to the power supply component 1.

[0064] Figure 6 This is a schematic diagram of the structure of an atomizer core holder provided in an embodiment of this application, as shown below. Figure 6 As shown, the atomizer core holder 241 may also be provided with a lead wire groove 241c and a wire passage hole 241b. The lead wire groove 241c is located on the side of the atomizer core holder 241 away from the atomizer core assembly 22, and the lead wire groove 241c connects the wire passage hole 241b and the electrode slot 241a. The lead wire 224 passes through the wire passage hole 241b and extends along the lead wire groove 241c into the electrode slot 241a.

[0065] The wire guide hole 241b facilitates the extension of the lead wire 224 to the side of the atomizer core bracket 241 near the atomizer core base 242. The lead wire groove 241c can accommodate the lead wire 224, which serves as a limit and can also prevent the lead wires 224 from contacting each other and causing a short circuit.

[0066] This application embodiment also provides an atomizer, the structure of which can be referred to... Figure 4 As shown, Figure 4 As shown, the atomizer 2 includes a liquid storage assembly 21 and any of the aforementioned atomizing modules 220. The liquid storage assembly 21 includes a liquid storage chamber housing 211 and a sealing base 212. The sealing base 212 is connected to the liquid storage chamber housing 211 to form a liquid storage chamber 20a for storing an aerosol matrix. The sealing base 212 has a socket 20b, through which the atomizing module 220 is detachably inserted into the liquid storage assembly 21. The mounting base 24 is located in the socket 20b and is sealed to the sealing base 212.

[0067] By applying the aforementioned atomizing module 220 to the atomizer 2, when assembling the atomizing module 220 with the liquid storage component 21, the atomizing core component 22 can be inserted into the liquid storage component 21, and the mounting base 24 can be detachably inserted into the sealing base 212 of the liquid storage component 21, forming a sealed fit with the sealing base 212. When the atomizing core component 22 cannot meet the user's requirements, the atomizing module 220 can be pulled out of the liquid storage component 21 entirely through the mounting base 24, and then the atomizing module 220 can be replaced and inserted into the liquid storage component 21. Since only the atomizing module 220 needs to be replaced, the cost of using the aerosol generating device can be greatly reduced.

[0068] Of course, since the atomizing module 220 and the liquid storage component 21 can be disassembled from each other, when the liquid storage component 21 cannot meet the user's requirements, for example, when the user wants to use a liquid storage component 21 that can store more aerosol matrix, the atomizing module 220 and the liquid storage component 21 can be separated, and the atomizing module 220 can be retained while other liquid storage components 21 are replaced.

[0069] Figure 7 This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of this application, as shown below. Figure 7 As shown, a partition plate 2111 is provided on the inner side of the liquid storage tank shell 211. The partition plate 2111 is connected to the inner wall of the liquid storage tank shell 211, and the partition plate 2111 and the inner wall of the liquid storage tank shell 211 form an air intake channel 2111a. One end of the air intake channel 2111a is connected to the atomizing core assembly 22. An air inlet 211a is also provided on the side wall of the liquid storage tank shell 211, and the air inlet 211a is connected to the air intake channel 2111a.

[0070] During use, outside air enters the atomizing core assembly 22, and the airflow carries the aerosol out. By forming an air intake channel 2111a on the inner wall of the liquid storage tank housing 211 and providing an air inlet 211a on the side wall of the liquid storage tank housing 211, outside air can enter the air intake channel 2111a through the air inlet 211a during the use of the atomizer 2, and then enter the atomizing core assembly 22 through the air intake channel 2111a, thus eliminating the need for an air inlet 212a on the sealing base 212. Because the air inlet 212a on the sealing base 212 is omitted, the risk of leakage of aerosol matrix, condensate, and other liquids from the sealing base 212 is also reduced.

[0071] like Figure 7 As shown, the sealing base 212 may include a liquid storage tank base 2122 and a liquid storage tank bottom cover 2123. The liquid storage tank base 2122 and the liquid storage tank bottom cover 2123 are arranged opposite to each other, with the liquid storage tank base 2122 located on the side of the liquid storage tank bottom cover 2123 closer to the liquid storage tank 20a. An air inlet chamber 212c is formed between the liquid storage tank base 2122 and the liquid storage tank bottom cover 2123, and the air inlet chamber 212c is connected to the air inlet channel 2111a and the atomizing core assembly 22, respectively.

[0072] The air intake channel 2111a and the atomizing core assembly 22 are connected by a sealing base 212, which has a simple structure. The air intake chamber 212c formed by the gap between the liquid storage tank base 2122 and the liquid storage tank bottom cover 2123 can serve as a channel for airflow, and can also store leaked liquid in the event of aerosol matrix leakage or condensate leakage in the atomizing core assembly 22, thus preventing liquid from blocking the air intake channel 2111a.

[0073] The insertion hole 20b can penetrate the liquid reservoir base 2122 and the liquid reservoir bottom cover 2123. As an example, the insertion hole 20b may include a first mounting hole 2123a penetrating the liquid reservoir bottom cover 2123 and a second mounting hole 2122a penetrating the liquid reservoir base 2122. The mounting base 24 can be inserted into the first mounting hole 2123a, and the atomizing core assembly 22 can be inserted into the second mounting hole 2122a. For example, the atomizing core base 242 can be inserted into the first mounting hole 2123a and sealed with it; the atomizing core cover 221 can be inserted into the second mounting hole 2122a and sealed with it.

[0074] For example, the mounting base 24 may also include a first seal 25, which may be sleeved on the atomizer core base 242 and is used to seal the gap between the atomizer core base 242 and the first mounting hole 2123a.

[0075] The sealing base 212 may further include a second seal 2124, which may be located on the side of the liquid storage tank base 2122 away from the liquid storage tank bottom cover 2123. A portion of the second seal 2124 may be located in the second mounting hole 2122a to seal the gap between the atomizing core outer cover 221 and the second mounting hole 2122a; a portion of the second seal 2124 may also be located between the liquid storage tank base 2122 and the liquid storage tank housing 211 to seal the gap between the liquid storage tank base 2122 and the liquid storage tank housing 211.

[0076] like Figure 7 As shown, the liquid storage tank base 2122 may have an opening 2122b on the side near the liquid storage tank 20a. The partition plate 2111 abuts against the liquid storage tank base 2122. The opening 2122b is positioned opposite to the end of the air intake channel 2111a. The opening 2122b connects the air intake chamber 212c and the air intake channel 2111a.

[0077] An opening 2122b is directly set on the base 2122 of the liquid storage tank to connect the air intake channel 2111a and the air intake chamber 212c, which is simple in structure.

[0078] like Figure 7 As shown, a portion of the second seal 2124 can also abut against the outer wall of the partition plate 2111 to form a seal, thereby sealing the gap between the partition plate 2111 and the liquid storage tank base 2122.

[0079] like Figure 7 As shown, the liquid storage assembly 21 may also include an air intake switch 213, which is movably mounted in the air intake channel 2111a. The air intake switch 213 is used to move along the air intake channel 2111a to change the area of ​​the air intake port 211a communicating with the air intake channel 2111a.

[0080] By changing the connection area between the air inlet 211a and the air intake channel 2111a, the draw resistance of the atomizer 2 during use can be adjusted, thus changing the air intake volume of the atomizer 2. When the atomizer 2 is idle, the connection area between the air inlet 211a and the air intake channel 2111a can be adjusted to 0, i.e., the air inlet 211a is closed, in order to maintain the air pressure in the air intake channel 2111a and the air intake chamber 212c, and prevent the aerosol matrix in the liquid storage tank 20a from leaking into the air intake chamber 212c through the atomizing core assembly 22.

[0081] Figure 8 This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of this application, as shown below. Figure 8As shown, the air intake switch 213 may include a shielding part 2131, which is in contact with the inner wall of the liquid storage tank housing 211. The shielding part 2131 and the inner wall of the liquid storage tank housing 211 are slidably sealed, that is, the shielding part 2131 is in a sealed fit with the inner wall of the liquid storage tank 20a, and can also slide relative to the liquid storage tank housing 211 to prevent air leakage between the shielding part 2131 and the inner wall of the liquid storage tank 20a.

[0082] The shielding part 2131 may have a plurality of first through holes 213a, which are distributed along the extending direction of the air intake passage 2111a. When the first through hole 213a is opposite to the air intake port 211a, the first through hole 213a connects the air intake port 211a and the air intake passage 2111a.

[0083] By arranging multiple first through holes 213a along the extension direction of the intake channel 2111a, the intake switch 213 can be moved along the intake channel 2111a to change the number of first through holes 213a opposite to the intake port 211a, thereby changing the area of ​​the intake port 211a connected to the intake channel 2111a and adjusting the intake volume.

[0084] like Figure 7 As shown, the liquid storage tank housing 211 also has a first sensing vent 211b, which is located at the end of the air intake channel 2111a. Specifically, it can be located at the end of the air intake channel 2111a away from the sealing base 212.

[0085] The sealing base 212 also has a second sensing vent 2123b, which is arranged opposite the end of the air intake channel 2111a.

[0086] As an example, the second sensing vent 2123b can be located on the bottom cover 2123 of the liquid storage tank, and the second sensing vent 2123b can be positioned directly opposite the opening 2122b.

[0087] The liquid storage assembly 21 also includes a gas guide tube 214, which is located in the air inlet channel 2111a. One end of the gas guide tube 214 is connected to the first sensing air hole 211b, and the other end of the gas guide tube 214 is connected to the second sensing air hole 2123b.

[0088] Since the nozzle 23 of the atomizer 2 is typically located at the end of the liquid storage tank housing 211 away from the sealing base 212, and the first sensing air port 211b and the second sensing air port 2123b are respectively arranged at both ends of the air intake channel 2111a, the first sensing air port 211b and the nozzle 23 are located at the same end of the liquid storage tank housing 211. During the use of the aerosol generating device, the atomizing core assembly 22 can operate under the control of the airflow sensor, which is typically located in the power supply assembly 1. During use, with the first sensing air port 211b also in the mouth, when inhaling with the nozzle 23, a change in air pressure at the first sensing air port 211b can be caused, generating airflow in the air guide tube 214, thereby causing a change in air pressure at the second sensing air port 2123b, triggering the airflow sensor in the power supply assembly 1.

[0089] like Figure 7 As shown, a suction nozzle 23 is provided at one end of the liquid storage tank shell 211 away from the sealing base 212, and the first sensing air hole 211b is connected to the inside of the suction nozzle 23.

[0090] For example, the end of the liquid storage tank housing 211 away from the sealing base 212 may be provided with an air guide groove 211c. The air guide groove 211c connects the first sensing air hole 211b and the suction nozzle 23, so that during the suction process, the airflow in the first sensing air hole 211b can enter the suction nozzle 23 through the air guide groove 211c, which can prevent the first sensing air hole 211b from being blocked and causing poor airflow.

[0091] like Figure 8 As shown, the intake switch 213 can slide with the air guide tube 214, thereby using the air guide tube 214 for guidance, making the movement of the intake switch 213 more stable.

[0092] Figure 9 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 9 As shown, the aerosol generating device includes a power supply component 1 and any of the aforementioned atomizers 2. The power supply component 1 is used to supply power to the atomizing core assembly 22.

[0093] In some examples, the power supply component 1 is detachably connected to the atomizer 2. Because the power supply component 1 is detachably connected to the atomizer 2, it is easy to replace the atomizer 2.
