[0038] Figure 1 is a structural schematic diagram of an aerosol generating device provided by an embodiment of the present application, as shown in Figure 1As shown, the aerosol-generating device includes a power supply assembly 100 and an atomizer 200. The power supply assembly 100 is configured to supply power to the atomizer 200.

[0039] Figure 2 is a schematic diagram of an internal structure of an atomizer provided by an embodiment of the present application, as shown, the atomizer 200 includes a liquid storage assembly 210 and an atomization assembly 220. The liquid storage assembly 210 is configured to store an aerosol substrate. The atomization assembly 220 is located in the liquid storage assembly 210, and the atomization assembly 220 is configured to heat the aerosol substrate, and the atomization assembly 220 forms an atomization channel 220a. Figure 2

[0040] The liquid storage assembly 210 can include a liquid tank shell 211, and an interior of the liquid tank shell 211 forms a liquid tank configured to contain the aerosol substrate. The liquid storage assembly 210 can further include a base 212, which can be fixedly connected or detachably connected to the liquid tank shell 211. The base 212 can be configured to mount an electrode 2121 to electrically connect with the power supply assembly 100.

[0041] In some examples, the liquid storage assembly 210 can further include a liquid storage member, for example, the liquid storage member can be liquid storage cotton, which is adsorbed or infiltrated with the aerosol substrate.

[0042] The atomization assembly 220 is located in the liquid tank shell 211. The atomization assembly 220 includes a tubular support 221, a liquid guide 222, a heating member 223, and a pin 224. The tubular support 221 forms the atomization channel 220a, and the liquid guide 222 and the heating member 223 are located in the tubular support 221. The pin 224 is electrically connected with the heating member 223.

[0043] The tubular support 221 provides a space in an interior of the liquid tank shell 211 to accommodate the liquid guide 222 and the heating member 223. The tubular support 221 can have holes, slits, or other structures on a tube wall thereof, so that the aerosol substrate in the liquid tank shell 211 can enter the atomization channel 220a and be absorbed by the liquid guide 222. The heating member 223 is configured to heat the aerosol substrate in the liquid guide 222 to vaporize the aerosol substrate.

[0044] The material and structure of the heating member 223 are not limited, as long as the heating member 223 can generate heat. For example, the heating member 223 can include at least one of a heating mesh, a heating film, a heating wire, and a heating sheet.

[0045] The pin 224 at an end thereof located outside the tubular support 221 penetrates the base 212 and contacts the electrode 2121 mounted on the base 212. A portion of the aerosol substrate entering the tubular support 221 from the liquid tank, for example, a portion of the aerosol substrate stored in the liquid guide 222, is prone to flow along the pin 224 to the electrode 2121, which can cause corrosion or oxidation of the electrode 2121 over a long period of time.​

[0046] Figure 3 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application, as shown below. Figure 3 As shown, the atomizing assembly 220 includes a tubular support 221, a heating element 223, a pin 224, and a first sealing element 225, with the heating element 223 located in the tubular support 221.

[0047] Figure 4 This is a schematic diagram of the internal structure of an atomizing component provided in an embodiment of this application, as shown below. Figure 4 As shown, the first seal 225 is located in the tubular support 221 and is located at one end of the heating element 223. A first airflow channel 225b is formed between the first seal 225 and the tubular support 221.

[0048] Figure 5 This is a schematic diagram of the internal structure of an atomizing component provided in an embodiment of this application, as shown below. Figure 5 As shown, the first seal 225 has a socket 225a. The pin 224 is inserted into the socket 225a and is sealed to the first seal 225. One end of the pin 224 is electrically connected to the heating element 223, and the other end of the pin 224 is located outside the tubular support 221.

[0049] By arranging a heating element 223 and a first sealing element 225 in a tubular support 221, the first sealing element 225 is located at one end of the heating element 223, forming a first airflow channel 225b between the first sealing element 225 and the tubular support 221. This allows airflow to enter the tubular support 221 through the first airflow channel 225b, mix with the atomized aerosol, and drive the aerosol out from the other end of the tubular support 221. The first sealing element 225 is provided with a socket 225a, into which a pin 224 electrically connected to the heating element 223 is inserted. The pin 224 and the first sealing element 225 are sealed together, preventing the aerosol matrix from flowing along the pin 224 to the surface of the electrode 2121. This avoids leakage of the aerosol matrix to the electrode 2121, which could cause corrosion and oxidation of the electrode 2121.

[0050] Furthermore, the sealing fit between the first seal 225 and the pin 224 prevents the aerosol matrix from continuing to flow out along the pin 224, thus reducing or avoiding leakage of the aerosol matrix at the electrode 2121, further reducing the risk of aerosol matrix leakage into the power supply component 100, and also reducing the waste of aerosol matrix.

[0051] like Figure 3As shown, the atomization assembly further includes a liquid guide 222 located in the tubular support 221, and the liquid guide 222 is formed with a second airflow passage 222a, and the heating element 223 is located in the second airflow passage 222a. Figure 4 The airflow direction of the partial region is schematically shown by arrows, as Figure 4 As shown, in the process of using the aerosol-generating device, the airflow enters the second airflow passage 222a from the first airflow passage 225b, and then is discharged from the end of the tubular support 221 away from the first seal 225, and the aerosol formed in the second airflow passage 222a is taken out of the atomization assembly 220.

[0052] As an example, the liquid guide 222 can include a liquid guide cotton 2221 and a ceramic tube 2222, the liquid guide cotton 2221 is sleeved outside the ceramic tube 2222, and the heating element 223 is located in the ceramic tube 2222. The heating element 223 can be attached to the inner wall of the ceramic tube 2222. The ceramic tube 2222 can play a role in heat insulation and uniform heating. The temperature generated by the heating element 223 is relatively high, and if the heating element 223 is directly in contact with the liquid guide cotton 2221, the liquid guide cotton 2221 may not be heated uniformly, and the area of the liquid guide cotton 2221 directly in contact with the heating element 223 may also be burned. By separating the heating element 223 and the liquid guide cotton 2221 by the ceramic tube 2222, the ceramic tube 2222 is heated by the heating element 223 and then transmits heat to the liquid guide cotton 2221, thereby heating the liquid guide cotton 2221, which can make the liquid guide cotton 2221 be heated more uniformly.

[0053] As shown, Figure 3 The atomization assembly 220 can include two pins 224, and the first seal 225 has two insertion holes 225a, and the pins 224 and the insertion holes 225a are arranged one by one.

[0054] As an example, as shown, Figure 5 The diameters of the two ends of the insertion hole 225a are greater than the diameter of the middle part.

[0055] The diameter of the end of the insertion hole 225a is set to be larger, which can facilitate the insertion of the pin 224 into the insertion hole 225a during the assembly of the atomization assembly 220. The diameter of the middle part of the insertion hole 225a is set to be smaller, so that the middle part of the insertion hole 225a and the pin 224 form an interference fit, providing a good sealing effect and avoiding leakage of the aerosol substrate. In addition, the larger diameter of the end of the insertion hole 225a forms a gap between the hole wall of the insertion hole 225a and the pin 224, and when the aerosol substrate in the liquid guide 222 flows along the pin 224, it can flow into and accumulate in the gap between the hole wall of the insertion hole 225a and the pin 224, avoiding the aerosol flowing along the pin 224 from leaking to the outside of the atomizer 200 along other possible paths.

[0056] AsFigure 5 As shown, the first seal 225 is located at one end of the liquid guide 222, and the through hole 225a is located outside the second airflow passage 222a in the orthographic projection of the end surface of the liquid guide 222. That is, the distance from the through hole 225a to the axis of the second airflow passage 222a is greater than the radius of the second airflow passage 222a, and the through hole 225a and the second airflow passage 222a of the liquid guide 222 are staggered with each other.

[0057] After the aerosol is accumulated in the gap between the hole wall of the through hole 225a and the pin 224, since the through hole 225a and the second airflow passage 222a of the liquid guide 222 are staggered with each other, the aerosol accumulated in the gap may flow back to the liquid guide 222 along the pin 224 in the case of inverting the atomization assembly, etc., so as to avoid waste of the aerosol.

[0058] As shown in FIG. 2A, the first seal 225 is located at one end of the liquid guide 222, and the through hole 225a is located outside the second airflow passage 222a in the orthographic projection of the end surface of the liquid guide 222. That is, the distance from the through hole 225a to the axis of the second airflow passage 222a is greater than the radius of the second airflow passage 222a, and the through hole 225a and the second airflow passage 222a of the liquid guide 222 are staggered with each other. Figure 4 Figure 5 As shown, the first seal 225 blocks the entrance of the second airflow passage 222a, and the first seal 225 and the liquid guide 222 have a gap, and the first airflow passage 225b is in communication with the gap.

[0059] The first seal 225 blocks the entrance of the second airflow passage 222a can mean that the projection of the entrance of the second airflow passage 222a on the surface of the first seal 225 is located in the first seal 225, and the projection is formed by projecting along the axis of the second airflow passage 222a to the end where the first seal 225 is located.

[0060] During the use of the aerosol generating device, a small amount of aerosol substrate may flow out of the second airflow passage 222a and drop onto the base 212, which may leak from the air inlet hole 212a of the base 212. By blocking the entrance of the second airflow passage 222a with the first seal 225, the aerosol substrate flowing out of the entrance of the second airflow passage 222a drops onto the surface of the first seal 225, rather than directly dropping onto the base 212, thereby reducing the risk of aerosol substrate leakage.

[0061] Although it is still possible for the aerosol to flow into the first airflow passage 225b along the surface of the first seal 225 and leak from the air inlet hole 212a of the base 212 after dropping onto the first seal 225, the amount of aerosol flowing out of the entrance of the second airflow passage 222a is usually small, and a relatively large amount of aerosol is required to flow along the surface of the first seal 225 to reach the base 212 after dropping onto the surface of the first seal 225. Therefore, blocking the entrance of the second airflow passage 222a with the first seal 225 is sufficient to avoid this type of leakage in most atomizers 200.

[0062] As shown in FIG. 2A, the first seal 225 is located at one end of the liquid guide 222, and the through hole 225a is located outside the second airflow passage 222a in the orthographic projection of the end surface of the liquid guide 222. That is, the distance from the through hole 225a to the axis of the second airflow passage 222a is greater than the radius of the second airflow passage 222a, and the through hole 225a and the second airflow passage 222a of the liquid guide 222 are staggered with each other. Figure 3 ​As shown, the first seal 225 has a first groove 225c on the side near the liquid guide 222, and the first airflow channel 225b connects to the end of the first groove 225c.

[0063] The first groove 225c increases the surface area of ​​the first seal 225, allowing more aerosol matrix to adhere to the surface, which helps prevent leakage. Additionally, by connecting the first airflow channel 225b to the end of the first groove 225c, the resistance to airflow from the first airflow channel 225b to the second airflow channel 222a is reduced.

[0064] like Figure 3 As shown, the first seal 225 has a second groove 225d on the side away from the liquid guide 222, and the first airflow channel 225b connects to the end of the second groove 225d.

[0065] The second groove 225d makes the structure of the first seal 225 near the liquid guide 222 similar to, or even identical to, the structure of the side of the first seal 225 away from the liquid guide 222. This makes the assembly of the first seal 225 easier when the pin 224 and the first seal 225 are assembled together, without strictly limiting the orientation of the two sides of the first seal 225. In addition, the second groove 225d can also prevent the first seal 225 from blocking the air inlet 212a on the base 212 and affecting the air intake. After the airflow enters the second groove 225d from the air inlet 212a, it can enter the first groove 225c through the first airflow channel 225b along the second groove 225d, and then enter the second airflow channel 222a through the first groove 225c.

[0066] like Figure 5 As shown, the first seal 225 is flush with the end face of the tubular support 221. This allows the first seal 225 to fit snugly against the base 212 when the atomizing assembly 220 is assembled to the base 212, eliminating the gap between the first seal 225 and the base 212. Thus, even if some aerosol matrix drips down the surface of the first seal 225 onto the base 212, this aerosol matrix is ​​prevented from flowing into the through-hole on the base 212 used to avoid the pin 224, further preventing aerosol matrix leakage onto the surface of the electrode 2121.

[0067] In other examples, the first seal 225 may also extend relative to the end face of the tubular support 221, so that the first seal 225 and the base 212 are pressed against each other, further improving the sealing performance.

[0068] like Figure 3As shown, the atomization assembly further comprises a second sealing member 226, which is located in the tubular support 221 and is located at the other end of the heating member 223 relative to the first sealing member 225.

[0069] By arranging the first sealing member 225 and the second sealing member 226, the leakage of the aerosol substrate from both ends of the tubular support 221 can be avoided.

[0070] Figure 6 is a structural schematic diagram of an atomizer provided by an embodiment of the present application, as Figure 6 shown, the atomizer 200 comprises a liquid storage assembly 210 and an atomization assembly 220. The liquid storage assembly 210 is used to store an aerosol substrate. The atomization assembly 220 can be Figures 3-5 any one of the atomization assemblies 220 shown. The atomization assembly 220 is located in the liquid storage assembly 210, and is used to heat the aerosol substrate to form an aerosol.

[0071] The first sealing member 225 is provided with a insertion hole 225a, and the pin 224 is inserted into the insertion hole 225a, and the pin 224 is in sealing cooperation with the first sealing member 225, so that the aerosol substrate is blocked by the first sealing member 225 and cannot flow along the pin 224 to the surface of the electrode 2121, thereby avoiding the leakage of the aerosol substrate to the electrode 2121 and causing corrosion and oxidation of the electrode 2121.

[0072] As Figure 6 shown, the liquid storage assembly 210 comprises a liquid tank shell 211 and a base 212. The base 212 has an air inlet hole 212a, and the base 212 further has a blocking edge 2122 surrounding the air inlet hole 212a, which can be located in the second groove 225d of the first sealing member 225. By arranging the blocking edge 2122, the leakage of the aerosol substrate dropped on the base 212 through the air inlet hole 212a can be avoided.

[0073] As Figure 6 shown, the liquid storage assembly 210 further comprises a third sealing member 213, which is located on the side of the base 212 close to the atomization assembly 220. The third sealing member 213 can seal the gap between the liquid tank shell 211 and the base 212, and the third sealing member 213 can also seal the gap between the outer wall of the tubular support 221 and the base 212, thereby improving the sealing performance of the liquid tank.

[0074] As an example, the atomizer 200 can further include a liquid injection assembly 230. The liquid injection assembly 230 includes a liquid injection tube cover 231, a liquid injection tube 232, an elastic member 233, and a fourth sealing member 234. The liquid injection tube cover 231 is inserted into the base 212, with one end of the liquid injection tube cover 231 located inside the liquid storage chamber and the other end located outside the liquid storage chamber. The liquid injection tube 232 is inserted into the liquid injection tube cover 231, with one end of the liquid injection tube 232 extending into the liquid storage chamber. The fourth sealing member 234 is located inside the liquid storage chamber and connected to the end of the liquid injection tube 232 extending into the liquid storage chamber. The end of the liquid injection tube 232 extending into the liquid storage chamber is closed, and the side wall of the liquid injection tube 232 has a liquid injection hole 232a. The elastic member 233 is connected between the liquid injection tube 232 and the liquid injection tube cover 231, and the elastic member 233 provides a force urging the liquid injection tube 232 to move out of the liquid storage chamber. Under the action of the elastic member 233, the fourth sealing member 234 is in close contact with the end of the liquid injection tube cover 231 to form a seal, and the liquid injection hole 232a is located inside the liquid injection tube cover 231.

[0075] As an example, the elastic member 233 can be a spring, which can be sleeved outside the liquid injection tube 232.

[0076] When it is necessary to supplement the aerosol substrate to the liquid storage chamber, an external device for injecting the aerosol substrate can be connected to the liquid injection tube 232, and then the liquid injection tube 232 is pushed into the liquid storage chamber, so that the elastic member 233 deforms under the action of the external force, the fourth sealing member 234 is separated from the end of the liquid injection tube cover 231, and the liquid injection hole 232a enters the liquid storage chamber. The aerosol substrate in the external device can enter the liquid storage chamber through the liquid injection tube 232 from the liquid injection hole 232a. After the aerosol substrate is supplemented, the liquid injection tube 232 is released, and under the action of the elastic member 233, the liquid injection tube 232 moves to the liquid injection hole 232a and returns to the liquid injection tube cover 231, and the fourth sealing member 234 is in close contact with the end of the liquid injection tube cover 231 to form a seal.

[0077] The embodiments of the present application also provide an aerosol generating device, which includes a power supply assembly and an atomizer 200 as shown in the drawings. The power supply assembly 100 is used to supply power to the atomization assembly 220. Figure 6

[0078] In some examples, the power supply assembly 100 is detachably connected to the atomizer 200. Since the power supply assembly 100 is detachably connected to the atomizer 200, the atomizer 200 can be conveniently replaced.
