Description

Technical Field

[0001] This application relates to the field of aerosol generating devices, and particularly to an atomizing core assembly, an atomizer, and an aerosol generating device. Background Technology

[0002] Common aerosol generating devices include an atomizer and a power supply unit, with the atomizer connected to the power supply unit. During operation, the power supply unit supplies power to the atomizer.

[0003] The atomizer includes a liquid reservoir assembly and an atomizer core assembly, with the core assembly housed within the reservoir assembly. The reservoir assembly comprises a sealing base and a reservoir housing, with the sealing base connected to the housing to form the reservoir. The atomizer core assembly is housed within the reservoir and connected to the sealing base. During operation, the aerosol matrix stored in the reservoir can enter the atomizer core assembly. The atomizer core assembly generates an aerosol by heating the aerosol matrix. The atomizer core assembly includes an atomizer core, a core support, and a core base, with the core base connected to one end of the core support. The core support and core base are electrically connected, and the core base can be reused as an electrode to electrically connect the atomizer core and a power supply assembly. The atomizer core is housed within the core support, with one pin extending to the end face of the core support near the core base and bent to contact the end face of the core support, thus forming an electrical connection.

[0004] When the pins are bent, their inherent stress can cause them to spring back, leading to unstable contact between the pins and the atomizer coil support. This unstable contact causes changes in the contact area, resulting in variations in contact resistance. Consequently, the heating power of the atomizer coil becomes unstable, affecting the atomization effect. Summary of the Invention

[0013] In some examples, the first insulating pad has a second end face facing away from the atomizing core support, and one end of the second pin electrically connected to the electrode block passes through the first socket and is bent to contact the second end face.

[0014] In some examples, the electrode block includes a second insertion portion and a third outer flange disposed on the outer peripheral wall of the second insertion portion, the second insertion portion being inserted into the first insertion hole, and the third outer flange abutting against the first insulating pad; The third outer flange is provided with a second notch, and the portion of the second pin that contacts the second end face is located in the second notch.

[0030] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application. Figure 1 ,like Figure 1 As 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] At least a portion of the atomizing core assembly 22 is located in the liquid storage assembly 21. Figure 3 yes Figure 2 The diagram shows the internal structure of the atomizer core assembly, as follows: Figure 3 As shown, the atomizer core assembly 22 includes an atomizer core cover 221, an atomizer core support 4, an atomizer core 3, and an atomizer core base 5. The atomizer core 3 includes a first liquid guide 31, a heating element 32, and pins 33. The first liquid guide 31 and the heating element 32 are located within the atomizer core support 4, and the atomizer core cover 221 is fitted over the atomizer core support 4. The pins 33 are electrically connected to the heating element 32. The pins 33 also extend to one end of the atomizer core support 4.

[0035] The atomizing core cover 221 can be cylindrical, and its wall can 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 first liquid guiding element 31. The atomizing core assembly 22 may also include a second liquid guiding element 34, which can be fitted over the atomizing core support 4. The second liquid guiding element 34 can block the holes and slits on the wall of the atomizing core cover 221, and the aerosol matrix in the liquid storage tank shell 211 can wet the second liquid guiding element 34.

[0036] The atomizing core support 4 may also be provided with holes, slits and other structures so that the aerosol matrix in the second liquid guiding component 34 can enter the atomizing core support 4 and be absorbed by the first liquid guiding component 31.

[0037] The heating element 32 is used to heat the aerosol matrix in the first liquid guiding element 31, causing the aerosol matrix to vaporize. The material and structure of the heating element 32 are not limited, as long as it can generate heat. For example, the heating element 32 may include at least one of the following: heating mesh, heating film, heating wire, and heating plate.

[0038] Heating element 32 may include one or more heating grids, for example, Figure 3 As shown, the heating element 32 includes a heating mesh.

[0039] Figure 4 This is a schematic diagram of the structure of an atomizing core assembly provided in an embodiment of this application. Figure 1 ,like Figure 4 As shown, the atomizing core assembly 22 includes an atomizing core 3, an atomizing core bracket 4, and an atomizing core base 5.

[0040] The atomizer core support 4 is cylindrical and has a first end and a second end. The atomizer core cover 221 can be fitted onto the first end of the atomizer core support 4.

[0041] Figure 5 This is a schematic diagram of the internal structure of an atomizing core assembly provided in an embodiment of this application. Figure 1 , Figure 5 and Figure 3 Different cross-sections of the atomizing core assembly 22 are shown. For example... Figure 5 As shown, the atomizer core holder 4 is sleeved outside the atomizer core 3, and the atomizer core 3 includes a first pin 331. One end of the first pin 331 is located in the atomizer core holder 4, and the end of the first pin 331 located inside the atomizer core holder 4 is used to connect to the heating element 32. The other end of the first pin 331 extends from the second end and is bent to contact the outer peripheral wall of the atomizer core holder 4.

[0042] The atomizer core base 5 is sleeved on the second end of the atomizer core bracket 4, so that the first pin 331 is clamped between the outer peripheral wall of the atomizer core bracket 4 and the inner peripheral wall of the atomizer core base 5, and the first pin 331 forms an electrical connection with the atomizer core bracket 4 and the atomizer core base 5.

[0043] For example, the atomizer core base 5 can be riveted to the second end of the atomizer core bracket 4.

[0044] By placing the atomizing core 3 within a tubular atomizing core support 4, and extending the first pin 331 of the atomizing core 3 from the second end of the atomizing core support 4 and bending it to contact the outer peripheral wall of the atomizing core support 4, an electrical connection is formed between the first pin 331 and the atomizing core support 4. By fitting the atomizing core base 5 onto the second end of the atomizing core support 4, the first pin 331 is clamped between the outer peripheral wall of the atomizing core support 4 and the inner peripheral wall of the atomizing core base 5. Under the clamping action of the atomizing core base 5 and the atomizing core support 4, a stable contact is formed between the first pin 331 and the atomizing core support 4 and the atomizing core base 5. This avoids unstable contact resistance caused by unstable contact of the first pin 331, which helps improve the stability of the atomizing core power and enhances the atomization effect.

[0045] like Figure 4 As shown, the atomizer core support 4 has a first outer flange 41, and the atomizer core base 5 abuts against the first outer flange 41. The first outer flange 41 has a first notch 41a, and the first pin 331 is located in the first notch 41a.

[0046] The first outer flange 41 facilitates the installation of the atomizing core base 5. During assembly, when the atomizing core bracket 4 and the atomizing core base 5 are assembled, the atomizing core base 5 is directly installed to abut against the first outer flange 41, and the first outer flange 41 is used to axially limit the atomizing core base 5.

[0047] During manufacturing, the pin 33 will be left with sufficient length. After assembly, it will be trimmed according to the actual installation situation to avoid the pin 33 being too short. When assembling the atomizer core assembly 22, when bending the first pin 331 to the outside of the atomizer core bracket 4, the length of the first pin 331 outside the atomizer core bracket 4 may be relatively long, which may abut against the first outer flange 41. By providing a first notch 41a on the first outer flange 41, the first pin 331 can be bent into the first notch 41a when bending, thus avoiding obstruction. Then, after assembling the atomizer core base 5, the excessively long part of the first pin 331 can be cut off from the first outer flange 41.

[0048] In addition, the first notch 41a can also serve as a mark to indicate the bending direction of the first pin 331, making it easier for operators to assemble the atomizing core assembly 22.

[0049] like Figure 5 As shown, the atomizer core holder 4 may be provided with a first air inlet 4a, which is located on the side of the first outer flange 41 away from the atomizer core base 5, that is, on the side of the first outer flange 41 near the first end of the atomizer core holder 4. The first pin 331 has a first end face located outside the atomizer core holder 4, which is flush with the surface of the first outer flange 41 away from the atomizer core base 5.

[0050] The first air inlet 4a of the atomizer core holder 4 is connected to the atomization channel 22a. When the user inhales through the mouthpiece 23, air can enter the atomization channel 22a through the first air inlet 4a. By setting the first air inlet 4a on the side of the first outer flange 41 away from the atomizer core base 5, that is, by placing the first air inlet 4a on the side wall of the atomizer core holder 4, leakage of the aerosol matrix from the end face of the atomizer core base 5 due to gravity can be avoided.

[0051] When assembling the atomizing core assembly 22, the first pin 331 can be trimmed to be flush with the surface of the first outer flange 41 away from the atomizing core base 5 when trimming the excess length of the first pin 331, so that the end of the first pin 331 is accommodated in the first notch 41a, thus preventing the end of the first pin 331 from protruding from the first notch 41a and affecting other structures inside the atomizer 2, and also preventing the first pin 331 from blocking the first air inlet 4a and affecting the airflow.

[0052] In some examples, the first air inlet 4a may be located adjacent to the first outer flange 41, and the edge of the first air inlet 4a near the first outer flange 41 may be flush with the surface of the first outer flange 41 away from the atomizing core base 5. The first air inlet 4a may be a strip-shaped opening extending circumferentially along the atomizing core support 4, and the first notch 41a may be located between the two opposite ends of the first air inlet 4a in the circumferential direction of the atomizing core support 4. In this way, when trimming the part of the first pin 331 that extends beyond the first notch 41a, the first air inlet 4a can avoid tools such as scissors, making it convenient to trim the first pin 331.

[0053] Figure 6 This is a schematic diagram of the structure of an atomizing core assembly provided in an embodiment of this application. Figure 2 , Figure 6 At least the atomizer coil base 5 is omitted. For example... Figure 6 A first groove 4b may be provided on the outer peripheral wall of the atomizer core support 4, and the first groove 4b extends from the end face of the second end of the atomizer core support 4 to the first notch 41a. The first pin 331 may be located in the first groove 4b.

[0054] The portion of the first pin 331 bent outside the atomizer core bracket 4 is accommodated in the first groove 4b. This prevents the height of the first pin 331 protruding too much relative to the outer peripheral wall of the atomizer core bracket 4, which would affect the assembly of the atomizer core base 5, and prevents the first pin 331 from being damaged or even broken due to excessive compression.

[0055] Reference Figure 5 As shown, the atomizer core assembly 22 may further include a first insulating pad 6, which is connected to the second end of the atomizer core support 4, and the first insulating pad 6 is interference-fitted with the atomizer core support 4. The first pin 331 is clamped between the atomizer core support 4 and the first insulating pad 6.

[0056] By installing the first insulating pad 6 to the second end of the atomizing core bracket 4 to form an interference fit with the atomizing core bracket 4, and by using the first insulating pad 6 to press the first pin 331 so that the first pin 331 is in close contact with the inner wall of the atomizing core bracket 4, the stability of the contact between the first pin 331 and the atomizing core bracket 4 can be improved.

[0057] For example, the first insulating pad 6 can be a flexible material, such as rubber or silicone. The flexible first insulating pad 6 can deform when the first pin 331 is compressed, forming a large contact area with the surface of the first pin 331, thus preventing the first pin 331 from being damaged by excessive local pressure. The flexible first insulating pad 6 can make good contact with the surface of the first pin 331 and the inner wall of the atomizing core support 4, enabling the first insulating pad 6 to achieve a good seal on the second end of the atomizing core support 4 and preventing leakage of the aerosol matrix.

[0058] like Figure 5 As shown, the first insulating pad 6 may include a first insertion portion 61 and a second outer flange 62 disposed on the outer peripheral wall of the first insertion portion 61. The first insertion portion 61 is inserted into the atomizing core support 4, and the second outer flange 62 abuts against the end face of the second end. The first pin 331 is clamped between the outer peripheral wall of the first insertion portion 61 and the inner peripheral wall of the atomizing core support 4, and between the second outer flange 62 and the end face of the second end.

[0059] The first insertion part 61 presses the first pin 331 against the outer side of the atomizer core support 4, so that the first pin 331 is in close contact with the inner sidewall of the atomizer core support 4, achieving stable contact. The second outer flange 62 presses the first pin 331 against the end face of the second end of the atomizer core support 4, so that the first pin 331 is in close contact with the end face of the second end of the atomizer core support 4, achieving stable contact.

[0060] Under the action of the first insulating pad 6 and the atomizing core base 5, the first pin 331 contacts the inner wall of the atomizing core bracket 4, the first plug-in part 61, the end face of the second end of the atomizing core bracket 4, the second outer flange 62, the outer wall of the atomizing core bracket 4, and the inner wall of the atomizing core base 5, respectively. It is clamped by the inner wall of the atomizing core bracket 4 and the first plug-in part 61, the end face of the second end of the atomizing core bracket 4 and the second outer flange 62, and the outer wall of the atomizing core bracket 4 and the inner wall of the atomizing core base 5. This greatly improves the stability of the contact between the first pin 331 and the atomizing core bracket 4 and the atomizing core base 5, and avoids unstable contact resistance caused by unstable contact.

[0061] Figure 7 This is a schematic diagram of the internal structure of an atomizing core assembly provided in an embodiment of this application. Figure 2 , Figure 7 , Figure 5 and Figure 3 Different cross-sections of the atomizing core assembly 22 are shown. For example... Figure 7 As shown, the atomizing core assembly 22 may also include an electrode block 7, which is disposed on the first insulating pad 6 and is insulated from the atomizing core base 5.

[0062] The atomizing core 3 may also include a second pin 332, one end of which is located in the atomizing core support 4, and the other end of which is electrically connected to the electrode block 7.

[0063] The first pin 331 is electrically connected to the atomizer core base 5, which can be reused as an electrode. The second pin 332 is electrically connected to the electrode block 7, which can be used as another electrode. The electrode block 7 is placed on the first insulating pad 6, which insulates the electrode block 7 from the atomizer core base 5, thus preventing a short circuit between the first pin 331 and the second pin 332.

[0064] For example, one of the first pin 331 and the second pin 332 can be a positive terminal and the other can be a negative terminal. For instance, the first pin 331 is a negative terminal pin used to connect to the negative terminal of the power supply component 1, and the second pin 332 is a positive terminal pin used to connect to the positive terminal of the power supply component 1.

[0065] The atomizer core base 5 is a conductive component, such as a metal structural component; the atomizer core support 4 can be a conductive component, such as a metal structural component, or an insulating component, such as a plastic or ceramic component. The electrode block 7 is a conductive component, such as a metal structural component.

[0066] In related technologies, the first pin 331 is electrically connected to the atomizer core base 5 via the atomizer core bracket 4, and the atomizer core bracket 4 must be a conductive component. However, in this embodiment, the first pin 331 is sandwiched between the outer peripheral wall of the atomizer core bracket 4 and the inner peripheral wall of the atomizer core base 5. Therefore, even if the atomizer core bracket 4 is an insulating component, the first pin 331 can still directly form an electrical connection with the atomizer core base 5.

[0067] In some examples, the electrode block 7 can be inserted into the first insulating pad 6. For example... Figure 7 As shown, the first insulating pad 6 may be provided with a first insertion hole 6a, which is connected to the atomizing core bracket 4.

[0068] That is, the first insulating pad 6 is annular. The first insulating pad 6 can be arranged coaxially with the atomizing core support 4.

[0069] The electrode block 7 is inserted into the first socket 6a, and the second pin 332 is clamped between the wall of the first socket 6a and the electrode block 7.

[0070] For example, the electrode block 7 is interference-fitted with the first socket 6a.

[0071] The second pin 332 is clamped between the electrode block 7 and the first insulating pad 6, thus fixing the second pin 332 during the installation of the electrode block 7. The compression between the flexible first insulating pad 6 and the electrode block 7 ensures that the second pin 332 is stably attached to the surface of the electrode block 7, preventing unstable contact. Furthermore, the flexible first insulating pad 6 can be press-fitted with the electrode block 7, forming a good seal between them and preventing leakage of the aerosol matrix from between the electrode block 7 and the wall of the first insertion hole 6a.

[0072] like Figure 7 As shown, the end of the second pin 332 that is electrically connected to the electrode block 7 can pass through the first socket 6a and be bent to contact the second end face of the first insulating pad 6, which is the surface of the first insulating pad 6 facing away from the atomizing core bracket 4.

[0073] By passing the second pin 332 through the first socket 6a and bending it outward from the first socket 6a, the electrode block 7 can be easily inserted into the first socket 6a, thus preventing the second pin 332 from moving axially along the first socket 6a or even coming out of the first socket 6a during the installation of the electrode block 7.

[0074] By bending the second pin 332 into contact with the surface of the first insulating pad 6 facing away from the atomizing core support 4, the first insulating pad 6 can axially limit the second pin 332, further preventing the second pin 332 from moving axially along the first socket 6a during the insertion of the electrode block 7.

[0075] Sufficient length can be reserved when manufacturing the second pin 332 to avoid the situation where the second pin 332 is too short to extend out of the first socket 6a during assembly. After bending the second pin 332 and assembling the electrode block 7, the second pin 332 can be trimmed to remove any excessively long parts.

[0076] like Figure 7 As shown, the electrode block 7 may include a second insertion portion 71 and a third outer flange 72 disposed on the outer peripheral wall of the second insertion portion 71. The second insertion portion 71 is inserted into the first insertion hole 6a, and the third outer flange 72 abuts against the first insulating pad 6.

[0077] The third outer flange 72 abuts against the first insulating pad 6, which can axially limit the electrode block 7 and improve the installation accuracy of the electrode block 7 in the first socket 6a axially.

[0078] In some examples, a second notch 7a may be provided on the third outer flange 72, and the portion of the second pin 332 that contacts the second end face is located in the second notch 7a, that is, the portion of the second pin 332 that is bent to contact the surface of the first insulating pad 6 facing away from the atomizing core support 4 is located in the second notch 7a.

[0079] By setting a second notch 7a to prevent the second pin 332 from bending to the part that contacts the surface of the first insulating pad 6 facing away from the atomizing core support 4, the third outer flange 72 can fit better against the first insulating pad 6, avoiding the formation of a gap between the third outer flange 72 and the first insulating pad 6, which is beneficial to improving the sealing performance.

[0080] After the electrode block 7 is assembled, the second pin 332 can be trimmed at the second notch 7a to remove the excessively long part of the second pin 332.

[0081] In some examples, a second and / or third groove may also be provided on the first insulating pad 6. The second groove may be provided on the outer wall of the first insulating pad 6, for example, on the outer peripheral wall of the first insertion portion 61 and on the surface of the second outer flange 62 near the atomizing core support 4. The second groove can be used to accommodate the first pin 331, avoiding excessive pressure between the first insulating pad 6 and the first pin 331, which would affect the installation of the first insulating pad 6. The first pin 331 can be press-fitted with the second groove to improve sealing. The third groove may be provided on the wall of the first insertion hole 6a. The third groove can be used to accommodate the second pin 332, avoiding excessive pressure between the first insulating pad 6 and the second pin 332, which would affect the installation of the electrode block 7. The second pin 332 can be press-fitted with the third groove to improve sealing.

[0082] like Figure 7 As shown, the atomizing core assembly 22 may further include a second insulating pad 8, which is annular and sleeved on the electrode block 7. The second insulating pad 8 separates the electrode block 7 from the atomizing core base 5.

[0083] The second insulating pad 8 and the first insulating pad 6 can be disposed on both sides of the third outer flange 72, respectively fitted onto both ends of the second insertion part 71. This not only supports both ends of the second insertion part 71, making the electrode block 7 more stable, but also isolates one end of the second insertion part 71 from the atomizing core support 4, thus insulating them; and the second insulating pad 8 isolates the other end of the second insertion part 71 from the atomizing core base 5, thus insulating them.

[0084] The second insulating pad 8 can be interference-fitted with the electrode block 7, and can also be interference-fitted with the inner peripheral wall of the atomizing core base 5 to improve the sealing performance of the atomizing core assembly 22.

[0085] For example, the second insulating pad 8 can be axially limited with the atomizer core base 5 by a stop structure to prevent the second insulating pad 8 from detaching from the atomizer core base 5.

[0086] like Figure 7 As shown, the outer peripheral wall of the atomizing core base 5 may also be provided with a fourth outer flange 51, which is located at the end of the atomizing core base 5 away from the first outer flange 41.

[0087] In some examples, the atomizer coil assembly 22 can be detachably connected to the liquid reservoir assembly 21, for example, the atomizer coil assembly 22 can be inserted into the sealing base 212. The atomizer coil assembly 22 can be easily installed and removed by providing a fourth outer flange 51 on the atomizer coil base 5.

[0088] An annular seal 9 may also be provided on the outer peripheral wall of the atomizing core base 5. The annular seal 9 is used to form a sealing fit with the sealing base 212 when the atomizing core assembly 22 is installed on the sealing base 212, so as to improve the sealing performance and prevent the aerosol matrix from leaking from the gap between the atomizing core base 5 and the sealing base 212.

[0089] As an example, in the atomizer 2 provided in this application embodiment, the liquid storage assembly 21 may include 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 second insertion hole 20b, through which the atomizing core assembly 22 is detachably inserted into the liquid storage assembly 21. The atomizing core base 5 is located in the second insertion hole 20b and is sealed to the sealing base 212.

[0090] 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 32. When the user desires a different heating effect, such as higher heating power, the user also needs to replace the atomizer 2. In these cases, replacing the atomizer 2 significantly increases the cost of using the aerosol generator.

[0091] For the atomizer 2 in this embodiment, when assembling the atomizing core assembly 22 and the liquid storage assembly 21, the atomizing core assembly 22 can be inserted into the second socket 20b, so that the atomizing core base 5 and the sealing base 212 are sealed together. The user can pull the atomizing core assembly 22 out of the second socket 20b as a whole through the atomizing core base 5, and then replace the atomizing core assembly 22 by inserting the replaced atomizing core assembly 22 into the second socket 20b. Since only the atomizing core assembly 22 needs to be replaced, and the entire atomizer 2 does not need to be replaced, the cost of using the aerosol generating device can be greatly reduced.

[0092] Of course, since the atomizing core assembly 22 and the liquid storage assembly 21 can be disassembled from each other, when the liquid storage assembly 21 cannot meet the user's requirements, for example, when the user wants to use a liquid storage assembly 21 that can store more aerosol matrix, the atomizing core assembly 22 and the liquid storage assembly 21 can be separated, and the atomizing core assembly 22 can be retained while other liquid storage assemblies 21 are replaced.

[0093] Reference Figure 2As 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. A second air inlet 211a is also provided on the side wall of the liquid storage tank shell 211, and the second air inlet 211a is connected to the air intake channel 2111a.

[0094] During use, outside air enters the atomizing core assembly 22 and is carried out by the airflow. By forming an air intake channel 2111a on the inner side wall of the liquid storage tank housing 211 and providing a second air intake port 211a on the side wall of the liquid storage tank housing 211, outside air can enter the air intake channel 2111a through the second air intake port 211a during the use of the atomizer 2, and then enter the atomizing core assembly 22 through the air intake channel 2111a. This eliminates the need to provide a through hole for air intake on the sealing base 212, thus reducing the risk of leakage of liquids such as aerosol matrix and condensate from the sealing base 212.

[0095] like Figure 2 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 first air inlet 4a of the atomizing core assembly 22, respectively.

[0096] An opening 2122b may be provided on the side of the liquid storage tank base 2122 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.

[0097] An opening 2122b is directly set on the liquid storage tank base 2122 to connect the air intake channel 2111a and the air intake chamber 212c, which is simple in structure.

[0098] The air intake chamber 212c is used to connect the air intake channel 2111a and the atomizing core assembly 22, resulting in 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, preventing liquid from blocking the air intake channel 2111a.

[0099] The second insertion hole 20b can penetrate the liquid storage tank base 2122 and the liquid storage tank bottom cover 2123. As an example, the second insertion hole 20b may include a first mounting hole 2123a penetrating the liquid storage tank bottom cover 2123 and a second mounting hole 2122a penetrating the liquid storage tank base 2122. The atomizing core base 5 can be inserted into the first mounting hole 2123a, and the atomizing core bracket 4 and the atomizing core cover 221 can be inserted into the second mounting hole 2122a. For example, the atomizing core base 5 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.

[0100] For example, the annular seal 9 is sleeved on the outside of the atomizing core base 5, and the annular seal 9 is used to seal the gap between the atomizing core base 5 and the first mounting hole 2123a.

[0101] 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.

[0102] like Figure 2 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.

[0103] like Figure 2 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 second air intake port 211a communicating with the air intake channel 2111a.

[0104] By changing the connection area between the second 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 second air inlet 211a and the air intake channel 2111a can be adjusted to 0, that is, the second 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.

[0105] like Figure 2 As 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.

[0106] The shielding portion 2131 may have one or more first through holes 213a. For example, when multiple first through holes 213a are provided, they may be distributed along the extending direction of the air intake passage 2111a. When a first through hole 213a is opposite to a second air intake port 211a, the first through hole 213a connects the second air intake port 211a and the air intake passage 2111a.

[0107] By arranging the first through hole 213a, the intake switch 213 can be moved along the intake channel 2111a to change the area of ​​the first through hole 213a relative to the second intake port 211a, thereby changing the area of ​​the second intake port 211a connected to the intake channel 2111a and adjusting the intake volume.

[0108] like Figure 2 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.

[0109] The sealing base 212 also has a second sensing vent 2123b, which is arranged opposite the end of the air intake channel 2111a.

[0110] 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.

[0111] 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.

[0112] The nozzle 23 may be provided with a third sensing air hole 211c, which is connected to the first sensing air hole 211b.

[0113] Since the nozzle 23 of the atomizer 2 is usually 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 usually located in the power supply assembly 1. During use, with the third sensing air port 211c also located in the mouth, when inhaling with the nozzle 23, the air pressure at the first sensing air port 211b can be changed through the third sensing air port 211c, causing airflow in the air guide tube 214, which in turn changes the air pressure at the second sensing air port 2123b, triggering the airflow sensor in the power supply assembly 1.

[0114] Figure 8 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application. Figure 2 ,like Figure 8 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 atomizer core assembly 22.

[0115] 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.
