Description

Technical Field

[0001] The present application relates to the field of aerosol generating devices, and in particular to a liquid storage assembly, an atomizer, and an aerosol generating device. Background Art

[0002] A common aerosol generating device includes a nebulizer and a power supply. The nebulizer and the power supply are detachably connected, so that the user can replace different nebulizers as needed.

[0003] The atomizer includes a liquid storage component and an atomizer core. The liquid storage component is used to store the aerosol matrix, and the atomizer core is located inside the liquid storage component. The atomizer core can absorb the aerosol matrix and heat the aerosol matrix to form an aerosol. The aerosol matrix is in a state of equilibrium in the atomizer core, which can both soak the atomizer core and not leak to the outside of the atomizer through the atomizer core. However, this balance is easily broken by external factors, resulting in the risk of leakage of the aerosol matrix. For example, during logistics transportation, it is prone to frequent external shocks, and the risk of leakage of the aerosol matrix is high.

[0004] To prevent leakage of the aerosol matrix before the nebulizer is put into use, some structure is usually installed in the nebulizer to separate the aerosol matrix from the atomizer core. The aerosol matrix only comes into contact with the atomizer core when the nebulizer is in use. However, such a nebulizer is often complex in structure and has a high production cost. Summary of the Invention

[0018] In some examples, the third air flow channel is located in a wall of the liquid tank housing opposite to the base.

[0019] In some examples, a nozzle air duct is formed in the liquid tank housing, one end of the nozzle air duct is located in the second accommodating cavity and is used to communicate with the atomization channel of the atomizer core, and the other end is connected to the outside of the liquid tank housing;

[0020] The electrode column includes a second electrode column, the second electrode column has a fourth air flow channel, and the liquid tank housing has a fifth air flow channel;

[0021] One end of the fourth airflow channel is connected to the nozzle airway through the fifth airflow channel; the other end of the fourth airflow channel is located at a portion of the second electrode column exposed from the housing, and is used to be connected to the airflow sensor.

[0022] In some examples, the inner wall of the liquid tank housing has a limit stop, and the partition is located on a side of the limit stop close to the base and contacts the limit stop.

[0023] In some examples, the partition further has a liquid injection through hole, and the liquid injection through hole connects the first accommodating cavity and the second accommodating cavity;

[0024] The liquid storage assembly further includes a sealing plug, which is located on a side of the partition close to the base and at least partially located in the liquid injection through hole.

[0025] In some examples, a surface of a portion of the electrode column located within the chamber has a passivation coating.

[0026] In some examples, the electrode column includes a non-metallic portion and a metal portion coaxially connected, the non-metallic portion is located within the chamber, and the metal portion is located outside the chamber.

[0027] In a second aspect, an embodiment of the present application further provides an atomizer, comprising an atomizer core and a liquid storage assembly as described in the first aspect, wherein the atomizer core is located in the second accommodating cavity, and the pins of the atomizer core are electrically connected to the electrode column.

[0028] In some examples, the atomizer further includes a seal, which is located in the second accommodating chamber and is sleeved outside the atomizing core and the electrode column; a portion of the pin is sandwiched between the electrode column and the seal.

[0031] In a third aspect, an embodiment of the present application provides an aerosol generating device, comprising a power supply and any one of the atomizers described in the second aspect, wherein the power supply is used to power the atomizer.

The first chamber can be used to hold the aerosol substrate, while the second chamber can be used to hold the atomizer core. The separator has a first through-hole connecting the first and second chambers. The electrode post is inserted into the chamber of the housing, mating with the first through-hole. The electrode post has a first and a second state. In the first state, the electrode post seals against the first through-hole, preventing the aerosol substrate in the first chamber from entering the second chamber. In the second state, a gap exists between the electrode post and the wall of the first through-hole, allowing the first through-hole to be open, allowing the aerosol substrate in the first chamber to enter the second chamber through the first through-hole. Placing the electrode post in the first state before the atomizer is put into use prevents the aerosol substrate from leaking out of the atomizer through the atomizer core, thereby significantly reducing the risk of aerosol substrate leakage before the atomizer is put into use. The first through hole is directly closed by the electrode column, and the electrode column can be used to power the atomizer core. That is to say, the electrode column realizes the functions of at least two components, so that the number of components of the atomizer can be reduced, the structure of the atomizer is simpler, and it is conducive to reducing production costs.

[0054] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of the present application. Figure 1As shown, the aerosol generating device includes a power source 100 and an atomizer 200. The power source 100 is used to supply power to the atomizer 200.

[0055] Figure 2 This is a schematic diagram of the internal structure of an aerosol generating device provided in an embodiment of the present application. Figure 2 As shown, the nebulizer 200 includes a liquid storage component 210 and an atomizing core 240. The liquid storage component 210 is used to store an aerosol matrix.

[0056] The liquid storage component 210 may include a liquid tank shell 211 and a base 212, and the liquid tank shell 211 and the base 212 form a liquid tank, which is used to contain the aerosol matrix. In some examples, the liquid storage component 210 may also include a liquid storage part, for example, the liquid storage part may be liquid storage cotton, and the liquid storage cotton is adsorbed / soaked with the aerosol matrix.

[0057] The base 212 can be fixedly or detachably connected to the liquid reservoir housing 211. The base 212 has an air inlet channel 2a and a sensing air channel 2b. The air inlet channel 2a and the sensing air channel 2b are connected to the atomizer core 240. The sensing air channel 2b is used to communicate with the airflow sensor in the power supply 100. During use of the aerosol generating device, ambient air can enter the atomizer 200 through the air inlet channel 2a. Airflow is also generated in the sensing air channel 2b, triggering the airflow sensor.

[0058] like Figure 2 As shown, the base 212 has a cavity 212a inside, and the atomizer core 240 is inserted into the base 212. The cavity 212a is opposite to the outer wall of the atomizer core 240, and the aerosol matrix in the cavity 212a can enter the atomizer core 240. The base 212 also has a socket 212b, and a push rod 213 is inserted into the socket 212b. One end of the push rod 213 is located outside the liquid storage component 210. When the push rod 213 is not pressed, the socket 212b is blocked by the push rod 213. After the push rod 213 is pressed into the liquid storage component 210, the socket 212b connects the cavity 212a with the liquid tank, as shown in FIG. Figure 2 As shown by the arrow in , the aerosol matrix in the liquid tank can enter the cavity 212a through the insertion hole 212b and contact the atomization core 240.

[0059] Although the aerosol matrix can be prevented from leaking out of the atomizer 200 through the atomizer core 240, such as from the air inlet channel 2a or the sensing air channel 2b, as long as the push rod 213 is not pressed, thus effectively reducing the risk of aerosol matrix leakage before the atomizer 200 is put into use, the base 212 has a complex structure and requires the push rod 213, which makes the overall structure of the atomizer 200 complex and the manufacturing cost high.

[0060] Figure 3This is a schematic structural diagram of a liquid storage component provided in an embodiment of the present application. Figure 3 As shown, the liquid storage assembly 210 includes a housing 21, a separator 22, and an electrode column 23. The housing 21 defines a chamber. The separator 22 is located within the chamber, dividing it into a first accommodating chamber 21a and a second accommodating chamber 21b. The first accommodating chamber 21a is used to accommodate the aerosol substrate, and the second accommodating chamber 21b is used to accommodate at least a portion of the atomizing core 240. The separator 22 has a first through hole 22a, which connects the first accommodating chamber 21a with the second accommodating chamber 21b.

[0061] The electrode column 23 is inserted into the aforementioned chamber, and a portion of the electrode column 23 is exposed outside the housing 21 .

[0062] Exemplarily, the electrode column 23 has two opposite ends, one end of which is inserted into the chamber and the other end is exposed from the housing 21 .

[0063] The electrode column 23 has a first state and a second state. Figure 4 This is a schematic structural diagram of a liquid storage component provided in an embodiment of the present application. Figure 4 The middle electrode column 23 is in the first state, Figure 4 As shown, in the first state, the electrode column 23 is sealed and matched with the first through hole 22a, so that the first through hole 22a is closed. Figure 5 This is a schematic structural diagram of a liquid storage component provided in an embodiment of the present application. Figure 5 The middle electrode column 23 is in the second state. Figure 5 As shown, in the second state, the electrode column 23 is separated from the hole wall of the first through hole 22a, and a gap exists between the electrode column 23 and the hole wall of the first through hole 22a, so that the first through hole 22a is conductive.

[0064] A separator 22 is provided in the housing 21, dividing the chamber within the housing 21 into a first accommodating chamber 21a and a second accommodating chamber 21b. The first accommodating chamber 21a can be used to accommodate aerosol substrate, while the second accommodating chamber 21b can be used to accommodate the atomizer core 240. The separator 22 has a first through-hole 22a connecting the first accommodating chamber 21a and the second accommodating chamber 21b. By inserting the electrode column 23 into the chamber of the housing 21, the electrode column 23 engages with the first through-hole 22a. The electrode column 23 has a first state and a second state. In the first state, the electrode column 23 seals against the first through-hole 22a, preventing aerosol substrate in the first accommodating chamber 21a from entering the second accommodating chamber 21b. In the second state, the electrode column 23 separates from the wall of the first through-hole 22a, allowing the first through-hole 22a to flow through, allowing aerosol substrate in the first accommodating chamber 21a to enter the second accommodating chamber 21b. Before the atomizer 200 is put into use, placing the electrode column 23 in the first state prevents the aerosol matrix from leaking out of the atomizer 200 through the atomizer core 240, thereby significantly reducing the risk of aerosol matrix leakage before the atomizer 200 is put into use. By directly using the electrode column 23 to seal the first through-hole 22a and power the atomizer core 240, the electrode column 23 fulfills the functions of at least two components, reducing the number of components in the atomizer 200 and simplifying its structure, thereby reducing manufacturing costs.

[0065] In the embodiment of the present application, "exposed" means visible or touchable from the outside. For example, the electrode column 23 being exposed from the outer shell 21 may mean that one end of the electrode column 23 can be touched from the outside of the outer shell 21. One end of the electrode column 23 may protrude from the outer surface of the outer shell 21, so that the user can directly touch the electrode column 23; one end of the electrode column 23 may also be flush with the outer surface of the outer shell 21 or recessed inward relative to the outer surface of the outer shell 21, so that the user can touch the electrode column 23 with the help of a tool, such as a rod-shaped object such as a screwdriver or a needle, or use a thimble provided on the power supply 100. For example, the thimble may be an electrode of the power supply 100. When the power supply 100 is connected to the atomizer 200, the end of the thimble contacts the end of the electrode column 23. The electrode column 23 being exposed from the outer shell 21 allows the user to touch the electrode column 23 directly with his hand or with the help of a tool, and operate the electrode column 23 to change the state of the electrode column 23.

[0066] In some examples, the electrode column 23 is mounted on the housing 21 in a manner that allows it to move relative to the housing 21. By moving the electrode column 23 relative to the housing 21, the state of the electrode column 23 can be changed, for example, from a first state to a second state. The movement of the electrode column 23 relative to the housing 21 can include at least one of sliding and rotating, as long as the electrode column 23 can close and connect the first through hole 22a.

[0067] As an example, the electrode column 23 is in sliding cooperation with the housing 21 and can move relative to the housing 21 along its own length direction, so that the electrode column 23 changes from the first state to the second state.

[0068] The electrode column 23 and the shell 21 are slidably matched, and the state of the electrode column 23 is changed by moving the electrode column 23 along the length direction of the electrode column 23. Not only is the structure relatively simple, but the space occupied by the electrode column 23 during movement is relatively small, and it will not affect the arrangement of other structures in the shell 21.

[0069] like Figure 5 As shown, the housing 21 includes a liquid tank shell 211 and a base 212. The liquid tank shell 211 and the base 212 are connected to form a chamber, and the second accommodating chamber 21b is located between the partition 22 and the base 212. The electrode column 23 is inserted into the base 212.

[0070] During use, the atomizer 200 must be connected to the power source 100, both mechanically and electrically. The base 212 is typically used for connection to the power source 100. Inserting the electrode column 23 into the base 212 facilitates electrical connection between the electrode column 23 and the power source 100.

[0071] like Figure 5 As shown, a nozzle air passage 211a is formed in the liquid reservoir housing 211. One end of the nozzle air passage 211a is located in the second accommodating chamber 21b. The nozzle air passage 211a is located at one end of the second accommodating chamber 21b and is used to communicate with the atomization channel 240a of the atomizer core 240. The other end of the nozzle air passage 211a is connected to the outside of the liquid reservoir housing 211.

[0072] The nozzle airway 211a can be used to connect the nozzle 214. As an example, the nozzle 214 can be integrally formed with the liquid tank housing 211. In other possible implementations, the nozzle 214 can also be detachably connected to the liquid tank housing 211 to facilitate replacement of the nozzle 214.

[0073] like Figure 5 As shown, the inner wall of the liquid tank housing 211 may have a limit stop 2111 . The partition 22 is located on a side of the limit stop 2111 close to the base 212 , and the partition 22 is in contact with the limit stop 2111 .

[0074] By arranging the stopper 2111 and placing the divider 22 on the side of the stopper 2111 close to the base 212, the assembly of the divider 22 and the liquid tank housing 211 can be facilitated. For example, before assembling the base 212 to the liquid tank housing 211, the divider 22 can be inserted from the open end of the liquid tank housing 211 and pushed until it contacts the stopper 2111.

[0075] In some examples, the partition 22 may further include a liquid injection hole 22b that connects the first accommodating chamber 21a and the second accommodating chamber 21b. The liquid storage assembly also includes a sealing plug 221, which is located on a side of the partition 22 near the base 212 and is at least partially located in the liquid injection hole 22b.

[0076] During the preparation of the atomizer 200, the liquid injection hole 22b can be used to inject aerosol substrate into the first accommodating chamber 21a. Because the sealing plug 221 is located on the side of the partition 22 near the base 212, after the aerosol substrate is injected, the sealing plug 221 can be inserted into the liquid injection hole 22b from the open end of the liquid reservoir housing 211 to seal the aerosol substrate, making the operation convenient.

[0077] One end of the sealing plug 221 may have a flange 2211, and the sealing plug 221 is located on the side of the separator 22 close to the base 212, which may mean that the flange 2211 of the sealing plug 221 is located on the side of the separator 22 close to the base 212. The sealing plug 221 may also be conical, and the sealing plug 221 is located on the side of the separator 22 close to the base 212, which may mean that the end of the sealing plug 221 with a larger diameter is located on the side of the separator 22 close to the base 212.

[0078] In some examples, a portion of the electrode column 23 located in the chamber of the housing 21 may be inserted into a wall of the liquid tank housing 211 .

[0079] The end of the electrode column 23 located within the chamber is inserted into the inner wall of the liquid reservoir housing 211, so that both ends of the electrode column 23 are supported by the base 212 and the liquid reservoir housing 211, respectively. In this example, the electrode column 23 extends through the first and second accommodating cavities 21a and 21b, and the electrode column 23 is relatively long. By supporting both ends of the electrode column 23, the installation and movement of the electrode column 23 are more stable.

[0080] like Figure 5 As shown, the electrode column 23 is covered with a first sealing ring 233. In a first state, the first sealing ring 233 is located in the first through hole 22a and is sealed with the first through hole 22a; in a second state, the first sealing ring 233 is located outside the first through hole 22a.

[0081] In this example, the electrode column 23 can move relative to the housing 21 along its own axial direction. During the movement of the electrode column 23, the first sealing ring 233 is driven to move, so that the first sealing ring 233 moves from the first through hole 22a to the outside of the first through hole 22a, thereby making the first through hole 22a conductive.

[0082] As an example, the outer wall of the electrode column 23 may have a first annular groove 23a, and the first sealing ring 233 may be located in the first annular groove 23a. Providing the first annular groove 23a to accommodate the first sealing ring 233 prevents the first sealing ring 233 from loosening and moving relative to the electrode column 23, thereby affecting the normal conduction of the first through hole 22a.

[0083] A second sealing ring 234 may be provided at the portion where the electrode column 23 and the housing 21 slide together. The second sealing ring 234 may be sleeved on the outside of the electrode column 23 to improve airtightness and reduce the risk of leakage of the atomizer 200.

[0084] like Figure 5 As shown, the electrode column 23 may include a first electrode column 231 and a second electrode column 232. The first electrode column 231 and the second electrode column 232 are respectively used to connect to the power supply 100. For example, the first electrode column 231 can be connected to the positive electrode of the power supply 100, and the second electrode column 232 can be connected to the negative electrode of the power supply 100.

[0085] Exemplarily, the positive electrode and the negative electrode of the power supply 100 may both be thimbles, and when the power supply 100 is connected to the atomizer 200 , the ends of the thimbles may contact the ends of the electrode columns 23 .

[0086] In some examples, the first electrode column 231 may have a first airflow channel 231a, and the base 212 may have a second airflow channel 212c. One end of the second airflow channel 212c is located in the second accommodating cavity 21b, and one end of the second airflow channel 212c is used to connect to the atomizer core 240. The other end of the second airflow channel 212c is connected to the first airflow channel 231a at least when the first electrode column 231 is in the second state.

[0087] The liquid tank housing 211 has a third air flow channel 211 b , which communicates with the first air flow channel 231 a and the outside of the liquid tank housing 211 .

[0088] During use of the atomizer 200, outside air will enter the atomizer 200. Typically, an air inlet channel 2a is provided on the base 212, through which outside air enters the atomizer 200. During use, the atomizer 200 is at risk of leakage. Aerosol substrate or condensed liquid may flow from the atomizer core 240 into the air inlet channel 2a located in the base 212 and leak through the air inlet channel 2a, causing waste and potentially staining clothing.

[0089] In this example, when the first electrode column 231 is in the second state, during use of the atomizer 200, air can enter the first air flow channel 231a through the third air flow channel 211b. Then, it can enter the third air flow channel 211b through the first air flow channel 231a, and then enter the atomizer core 240 from the third air flow channel 211b. This eliminates the need for an air inlet channel 2a in the base 212, thus preventing leakage from the base 212.

[0090] like Figure 4 As shown, the side wall of the first electrode column 231 has a second through hole 231b. Figure 4 In the first state, the second through hole 231b and the second air flow channel 212c are staggered with each other; Figure 5 In the second state, the second through hole 231b is connected to the second air flow channel 212c, so that the first air flow channel 231a and the second air flow channel 212c are in communication.

[0091] When the first electrode column 231 is in the first state, the second through hole 231b and the second air flow channel 212c are offset from each other, so that the air path from the third air flow channel 211b to the second air flow channel 212c is disconnected. Even if the seal between the first electrode column 231 and the separator 22 fails before the atomizer 200 is put into use, such as during transportation, causing the aerosol substrate stored in the first accommodating chamber 21a to enter the second accommodating chamber 21b prematurely, the aerosol substrate is unlikely to leak from the third air flow channel 211b along the air path to the outside of the atomizer 200, further reducing the risk of leakage before the atomizer 200 is put into use.

[0092] The sidewall of the first electrode column 231 may have a plurality of second through holes 231b, which are distributed along the circumference of the first electrode column 231, thereby increasing the area of communication between the first airflow channel 231a and the second airflow channel 212c, and facilitating airflow.

[0093] like Figure 5 As shown, the third air flow channel 211 b is located in the wall of the liquid tank housing 211 opposite to the base 212 .

[0094] For example, the liquid tank housing 211 may be in the shape of a long cylinder, with one end of the liquid tank housing 211 open and connected to the base 212, and the third air flow channel 211b located at the other end of the liquid tank housing 211. As an example, a suction nozzle 214 may be integrally formed at one end of the liquid tank housing 211 away from the base 212, and the third air flow channel 211b may be located on one side of the suction nozzle 214.

[0095] The third air flow channel 211b is arranged in the wall of the liquid tank housing 211 opposite to the base 212, so that the path for air to enter the atomizer core 240 from the outside of the atomizer 200 is longer. This longer path can reduce the risk of aerosol matrix or condensed liquid leaking from the third air flow channel 211b in the opposite direction to the outside of the atomizer 200 during use of the atomizer 200. In addition, this arrangement makes the extension direction of the first air flow channel 231a parallel or approximately parallel to the extension direction of the atomization channel 240a of the atomizer core 240, and the airflow direction in the first air flow channel 231a is opposite or approximately opposite to the airflow direction in the atomizer core 240, further reducing the risk of liquid in the atomizer core 240 leaking from the third air flow channel 211b to the outside of the atomizer 200.

[0096] In addition, when using the atomizer 200, the user usually holds the side wall of the atomizer 200. Arranging the third air flow channel 211b in the wall opposite to the base 212 can also reduce the risk of the third air flow channel 211b being blocked by the hand, ensuring that the air path is unobstructed.

[0097] like Figure 5 As shown, the second electrode column 232 has a fourth airflow channel 232a, and the liquid reservoir housing 211 has a fifth airflow channel 211c. One end of the fourth airflow channel 232a is connected to the nozzle airway 211a through the fifth airflow channel 211c. The other end of the fourth airflow channel 232a is located in the portion of the second electrode column 232 exposed from the housing 21 and is connected to the airflow sensor.

[0098] The airflow sensor is connected to the mouthpiece airway 211a through the fourth airflow channel 232a and the fifth airflow channel 211c, so that the airflow sensor can still be triggered normally during use of the aerosol generating device, and liquids such as aerosol matrix and condensate are prevented from leaking to the outside of the nebulizer 200 through the sensing airway 2b.

[0099] In this example, first airflow channel 231a, second airflow channel 212c, and third airflow channel 211b form a main airflow path, while fourth airflow channel 232a and fifth airflow channel 211c form a sensing airflow path. The main airflow path typically has a higher airflow volume, while the sensing airflow path typically has a lower airflow volume. The relative independence of the main and sensing airflow paths means that changes in the airflow volume of the sensing airflow path are less affected by changes in the airflow volume of the main airflow path, which helps improve the sensitivity of the airflow sensor and better trigger the airflow sensor.

[0100] In some examples, the surface of the portion of the electrode column 23 located in the chamber has a passivation coating, for example, the surface of at least one of the first electrode column 231 and the second electrode column 232 has a passivation coating.

[0101] The passivation layer may refer to a film layer that can remain stable when immersed in the aerosol matrix and does not chemically react with the aerosol matrix.

[0102] In this example, the electrode column 23 extends through both the first and second accommodating cavities 21a and 21b, placing it in prolonged contact with the aerosol matrix. This aerosol matrix could chemically react with the electrode column 23, causing corrosion. The products of this chemical reaction could also deteriorate the aerosol matrix, affecting its proper use. A passivating coating is formed on the surface of the electrode column 23 to isolate the aerosol matrix and prevent chemical reactions between the electrode column 23 and the aerosol matrix.

[0103] Figure 6 This is a schematic structural diagram of an electrode column provided in an embodiment of the present application. Figure 6 Taking the first electrode column 231 as an example, the electrode column 23 may include a coaxially connected non-metallic portion 235 and a metallic portion 236. The non-metallic portion 235 is located within the chamber of the housing 21, and the metallic portion 236 is located outside the chamber. The "inside the chamber" here refers to the space enclosed by the inner wall of the liquid reservoir shell 211 and the base 212. The "outside the chamber" may include the exterior of the housing 21 or the interior of the housing 21 wall, such as the channel in the base 212 where the electrode column 23 is inserted.

[0104] The metal portion 236 is formed of a metal material. The non-metal portion 235 is formed of a non-metal material, for example, a non-metal material that can remain stable when immersed in the aerosol matrix and does not chemically react with the aerosol matrix.

[0105] The portion of the electrode column 23 located within the chamber of the housing 21 comes into contact with the aerosol matrix. By placing the non-metallic portion 235 within the chamber and the metal portion 236 outside the chamber, chemical reactions between the metal portion 236 and the aerosol matrix can be avoided. The conductivity of the metal portion 236 allows the electrode column 23 to still be electrically connected to the atomizer core 240 for power supply.

[0106] Figure 7 This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of the present application. Figure 7 As shown, the atomizer 200 includes an atomizing core 240 and Figures 3 to 6 Any of the liquid storage components 210 shown. The atomizer core 240 is located in the second accommodating cavity 21 b of the liquid storage component 210 , and the pin 245 of the atomizer core 240 is electrically connected to the electrode column 23 .

[0107] like Figure 7As shown, the atomizing core 240 may include an outer cover 241, a tubular support 242, a liquid guide 243, a heater 244, and a pin 245. The outer cover 241 is sleeved on the outside of the tubular support 242. The side walls of the outer cover 241 and the tubular support 242 both have hollow structures, such as holes, openings, and gaps, so that the aerosol matrix can enter the inside of the tubular support 242. An atomizing channel 240a is formed inside the tubular support 242, and the liquid guide 243 is located in the atomizing channel 240a. The liquid guide 243 is used to absorb the aerosol matrix in the liquid storage tank. The heater 244 can be located inside the liquid guide 243 to heat the aerosol matrix, thereby forming an aerosol.

[0108] The material and structure of the heating element 244 are not limited as long as it can generate heat. For example, the heating element 244 may include at least one of a heating mesh, a heating film, a heating wire, and a heating plate.

[0109] The pin 245 is connected to the heater 244 for supplying power to the heater 244. The atomizer core 240 may include at least two pins 245.

[0110] As an example, the atomizer core 240 includes two pins 245 , one of the two pins 245 is electrically connected to the first electrode column 231 , and the other of the two pins 245 is electrically connected to the second electrode column 232 .

[0111] Exemplarily, the pin 245 may be in sliding contact with the electrode column 23 to prevent the pin 245 from affecting the movement of the electrode column 23 .

[0112] Figure 8 FIG. 1 is a schematic diagram of the internal structure of a nebulizer provided in an embodiment of the present application, showing the structure of the nebulizer at the second accommodating chamber 21b. Figure 8 As shown, the atomizer core 240 further includes a seal 246. The seal 246 is located in the second accommodating cavity 21b and is sleeved over the atomizer core 240 and the electrode column 23. Part of the pin 245 is sandwiched between the electrode column 23 and the seal 246.

[0113] The seal 246 is disposed within the second accommodating chamber 21b, sealing the gap between the liquid reservoir housing 211 and the base 212. It also provides a seal for the atomizer core 240, preventing aerosol matrix in the second accommodating chamber 21b from entering the atomizer core 240 through the end of the atomization channel 240a. The seal 246 is elastic, and by arranging a portion of the pin 245 between the electrode column 23 and the seal 246, the elastic force of the seal 246 can be used to force the pin 245 against the surface of the electrode column 23, ensuring a reliable electrical connection.

[0114] Exemplarily, the sealing member 246 may be a silicone member.

[0115] like Figure 8 As shown, the seal 246 has a third through-hole 246a and a fourth through-hole 246b. The atomizer core 240 is located in the third through-hole 246a, and the electrode column 23 is located in the fourth through-hole 246b. The pin 245 of the atomizer core 240 includes a first portion 2451, a second portion 2452, and a third portion 2453. The first portion 2451 is located in the third through-hole 246a and is connected to the heater 244 of the atomizer core 240. The second portion 2452 is located in the fourth through-hole 246b and is sandwiched between the outer wall of the electrode column 23 and the wall of the fourth through-hole 246b. The third portion 2453 is located on the side of the seal 246 away from the separator 22 and connects the first portion 2451 and the second portion 2452.

[0116] By bending the pin 245 into a U-shape and inserting the end of the pin 245 away from the heater 244 into the fourth through hole 246b, the pin 245 is tightly attached to the wall of the fourth through hole 246b and the outer wall of the electrode column 23 due to the elasticity of the seal 246. The U-shaped pin 245 can also be clamped on the seal 246, keeping the pin 245 stable and not easily loosened.

[0117] like Figure 8 As shown, a magnetic member 2121 may be further provided on the side of the base 212 away from the sealing member 246 . The magnetic member 2121 may adsorb the power supply 100 to connect the atomizer 200 and the power supply 100 .

[0118] Figure 9 This is a schematic diagram of the structure of a base provided in an embodiment of the present application. Figure 9 As shown, the second air flow channel 212c of the base 212 may include a fifth through hole 212d and a groove 212e. The groove 212e may be located on the surface of the base 212 close to the sealing member 246. The fifth through hole 212d connects the groove 212e and the atomization channel 240a of the atomization core 240.

[0119] The base 212 may have an annular boss on one side close to the sealing member 246 , the groove 212 e surrounds the annular boss, and the fifth through hole 212 d connects the inner and outer sides of the annular boss. The annular boss is aligned with the third through hole 246 a.

[0120] The end surface of the annular boss may further have a slot 212f, and the third portion 2453 of the pin 245 may be located in the slot 212f to limit the pin 245 and make the arrangement of the pin 245 more stable.

[0121] In other possible implementations, the second airflow channel 212c can also be a groove located on the surface of the base 212, that is, the annular boss is not provided on the side of the base 212 near the seal 246. By machining a groove on the surface to serve as the second airflow channel 212c, the manufacturing process can be simplified and the production cost can be lowered. The seal 246 can cooperate with the base 212 to seal the second airflow channel 212c, preventing the aerosol substrate in the second receiving chamber 21b from entering the second airflow channel 212c.

[0122] Figure 10 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of the present application. Figure 10 As shown, the aerosol generating device includes a nebulizer 200 and a power source 100 for supplying power to the nebulizer 200 .

[0123] The atomizer 200 can be Figures 7 to 9 Any of the nebulizers shown.

[0124] Figure 10 The structures of the atomizer 200 and the power supply 100 in the aerosol generating device shown are merely examples. In other possible implementations, the structures of the atomizer 200 and the power supply 100 in the aerosol generating device may also be different from those shown in the figure.
