[0044] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of this application, as shown below. Figure 1 As shown, the aerosol generating device includes a power supply component 100 and an atomizer 200. The power supply component 100 is used to supply power to the atomizer 200.

[0045] 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 200 includes a liquid storage assembly 210, an atomizing assembly 220, and a nozzle 230. The liquid storage assembly 210 is used to store the aerosol matrix. The atomizing assembly 220 is located in the liquid storage assembly 210 and is used to heat the aerosol matrix. The atomizing assembly 220 forms an atomizing channel 220a. The nozzle 230 is connected to one end of the atomizing channel 220a.

[0046] The liquid storage assembly 210 may include a liquid reservoir housing 211, the interior of which forms a liquid reservoir for containing the aerosol matrix. The liquid storage assembly 210 may also include a base 212, which may be fixedly connected to or detachably connected to the liquid reservoir housing 211. The base 212 may be used to mount electrodes 2121 for electrical connection to the power supply assembly 100. The base 212 may also have an air inlet 212a communicating with the atomization channel 220a, allowing outside air to enter the atomization channel 220a through the air inlet 212a.

[0047] In some examples, the liquid storage assembly 210 may also include a liquid storage element, such as a liquid storage cotton that has been adsorbed / wetted with an aerosol matrix.

[0048] The atomizing assembly 220 is located within the liquid tank housing 211. The atomizing assembly 220 includes a tubular support 221, a liquid guide 222, a heating element 223, and a pin 224. The liquid guide 222 and the heating element 223 are located within the tubular support 221. The pin 224 is electrically connected to the heating element 223.

[0049] The tubular support 221 provides space inside the liquid tank housing 211 to accommodate the liquid guiding component 222 and the heating component 223. The tubular support 221 may have structures such as holes and slits on its wall to allow the aerosol matrix in the liquid tank housing 211 to enter the atomization channel 220a and be absorbed by the liquid guiding component 222. The heating component 223 is used to heat the aerosol matrix in the liquid guiding component 222, causing the aerosol matrix to vaporize.

[0050] During the operation of the atomizer 200, leakage may occur at the base 212, which can easily stain the user's skin and clothing, severely affecting the user experience. Research has found that some of the aerosol matrix or condensate formed within the atomization component 220 may leak from the base 212 through the atomization channel 220a, for example, through the air inlet 212a, causing leakage.

[0051] 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 an atomizing core 22, an air guide tube 23, and a cover 24. The cover 24 is annular and fits around one end of the air guide tube 23, connecting to the wall of the air guide tube 23.

[0052] For example, the air duct 23 and the cover 24 can be an integral structural component.

[0053] 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 atomizing core 22 has an atomizing channel 220a, and the air guide tube 23 is located in the atomizing channel 220a. The cover 24 is located at the entrance of the atomizing channel 220a and is sealed to the atomizing channel 220a.

[0054] By setting an atomizing core 22, an air guide tube 23, and a cover 24 in the atomizing assembly 220, with the cover 24 fitted over one end of the air guide tube 23 and connected to it, the air guide tube 23 is arranged in the atomizing channel 220a of the atomizing core 22, and the cover 24 is arranged at the entrance of the atomizing channel 220a, forming a sealed fit with the atomizing channel 220a. This allows the liquid generated inside the atomizing assembly 220 to be blocked by the cover 24 in the atomizing core 22 during the operation of the atomizer 200, preventing leakage to the outside of the atomizing assembly 220, thereby reducing the risk of liquid leakage from the atomizer 200.

[0055] The liquid referred to in the embodiments of this application may include at least one of the following: leaked aerosol matrix and generated condensate.

[0056] like Figure 3As shown, the atomizing core 22 of the atomizing assembly 220 includes an atomizing core cover 2211 and a liquid guiding component 222, which is located within the atomizing core cover 2211. Both the liquid guiding component 222 and the atomizing core cover 2211 are fitted over the air guide tube 23, with a gap between the liquid guiding component 222 and the air guide tube 23. The end of the air guide tube 23 away from the cover 24 extends out to the liquid guiding component 222.

[0057] The atomizing core cover 2211 may have a hollow structure, such as through holes, so that the aerosol matrix in the liquid storage component 210 can enter the inside of the atomizing core cover 2211 and be absorbed by the liquid guiding component 222.

[0058] By making the air guide tube 23 relatively long, so that the end of the air guide tube 23 away from the cover 24 extends out of the liquid guide component 222, the possibility of the aerosol matrix in the liquid guide component 222 and the condensate formed in the atomization channel 220a entering the air guide tube 23 and leaking to the outside of the atomization assembly 220 through the air guide tube 23 can be reduced, thereby reducing the risk of liquid leakage of the atomizer 200.

[0059] In some examples, the end of the air duct 23 away from the cover 24 can be sealed to the outlet of the atomizing channel 220a to prevent leakage of aerosol and aerosol matrix from the outlet of the atomizing channel 220a.

[0060] like Figure 3 As shown, the atomizing core 22 may also include an atomizing core support 2212. A portion of the atomizing core support 2212 is located within the atomizing core cover 2211 and is fitted over the liquid guiding component 222. The other portion of the atomizing core support 2212 is located outside the atomizing core cover 2211, connected to the atomizing core cover 2211, and fitted over the cover 24.

[0061] The atomizing core support 2212 is fitted over the liquid guiding component 222 and serves to support the liquid guiding component 222. The atomizing core support 2212 may also have a hollow structure, such as through holes, so that the aerosol matrix in the liquid storage component 210 can enter the inside of the atomizing core support 2212 and be absorbed by the liquid guiding component 222.

[0062] like Figure 4 As shown, one end of the atomizing core cover 2211 can be fitted over the atomizing core support 2212. The atomizing core cover 2211 and the atomizing core support 2212 form a cavity, and the liquid guiding component 222 is located in the cavity.

[0063] The atomizing core 22 may also include a heating element 223, which may be located between the liquid guide 222 and the air guide tube 23. For example, it may be in contact with the inner wall of the liquid guide 222. The heating element 223 is used to heat the liquid guide 222 to form an aerosol.

[0064] The material and structure of the heating element 223 are not limited, as long as it can generate heat. For example, the heating element 223 may include at least one of heating mesh, heating film, heating wire, and heating plate.

[0065] The atomizing component 220 may also include an outer layer 225, which may be located between the atomizing core cover 2211 and the atomizing core support 2212, and wrap around the portion of the atomizing core support 2212 located inside the atomizing core cover 2211.

[0066] For example, the outer layer 225 can be non-woven fabric or cotton fiber.

[0067] like Figure 4 As shown, the air duct 23 may include a first air duct 231 and an end air duct 232. The first air duct 231 has a first end and a second end, wherein the first end is the end of the first air duct 231 near the cover 24. The first end of the first air duct 231 is closed, and the side wall of the first air duct 231 has a first air inlet 2311a. One end of the end air duct 232 is connected to the first end of the first air duct 231, and the other end of the end air duct 232 is connected to the cover 24. The side wall of the end air duct 232 has an air outlet 232a.

[0068] During atomization, air can enter the end air tube 232 and enter the atomization channel 220a through the air outlet 232a on the side wall of the end air tube 232, where it mixes with the generated aerosol. The mixed airflow can enter the first air tube 231 through the first air inlet 2311a on the side wall of the first air tube 231, and eventually leave the atomization assembly 220. During the operation of the aerosol generating device, liquid can only leak from the bottom of the atomizer 200 if it enters the end air tube 232 through the air outlet 232a. Since the air outlet 232a is located on the tube wall of the end air tube 232, it is difficult for liquid to enter, greatly reducing the risk of leakage. Liquid entering the first air tube 231 through the first air inlet 2311a will also flow to the closed end of the first air tube 231 under the action of gravity, temporarily stored in the first air tube 231, and will not leak outside the atomization assembly 220. Under the heating action of the heating element 223, the liquid temporarily stored in the first air tube 231 may gradually vaporize and leave the air guide tube 23. Even if the liquid temporarily stored in the first air tube 231 is not completely vaporized, when the aerosol generating device is placed at an angle or laid down, such as horizontally, the liquid in the first air tube 231 can flow back into the atomizing channel 220a through the first air inlet 2311a and be absorbed by the liquid guide element 222.

[0069] In some examples, at most one of the first air inlet 2311a and air outlet 232a is located at the end of the liquid guide 222 away from the cover 24. And / or, at most one of the first air inlet 2311a and air outlet 232a is located at the end of the liquid guide 222 near the cover 24.

[0070] For example, the first air inlet 2311a is located at the end of the liquid guide 222 away from the cover 24, and the air outlet 232a can be located at the end of the liquid guide 222 close to the cover 24, or the air outlet 232a can be located inside the liquid guide 222.

[0071] For example, the air outlet 232a is located at the end of the liquid guide 222 near the cover 24, and the first air inlet 2311a can be located at the end of the liquid guide 222 away from the cover 24, or the first air inlet 2311a can be located on the inner side of the liquid guide 222.

[0072] If the first air inlet 2311a and the air outlet 232a are arranged at the same end of the liquid guiding member 222, the distance between the first air inlet 2311a and the air outlet 232a will be relatively short. Air flowing out of the air outlet 232a will then enter the first air inlet 2311a after a shorter path in the atomization channel 220a, resulting in less aerosol being carried and thus less aerosol being discharged from the nozzle 230. In this embodiment, by avoiding arranging the first air inlet 2311a and the air outlet 232a at the same end of the liquid guiding member 222, and by making the first air inlet 2311a and the air outlet 232a farther apart, more aerosol can be carried into the first air inlet 2311a.

[0073] like Figure 4 As shown, there may be a gap between the liquid guide 222 and the air guide tube 23.

[0074] During operation, the liquid guide 222 of the atomizing component 220 releases aerosol. By forming a gap between the liquid guide 222 and the air guide tube 23, the inner wall of the liquid guide 222 can also release aerosol normally, which helps to improve atomization efficiency.

[0075] Although the liquid guide 222 typically has numerous pores, the gap between the liquid guide 222 and the air guide tube 23 allows airflow to directly pass through this gap from the outlet 232a of the end air tube 232 to the first inlet 2311a of the first air tube 231 during suction. This significantly reduces airflow resistance and improves the user's suction experience. Furthermore, the airflow can carry a large amount of aerosol as it flows through this gap.

[0076] As an example, the end air tube 232 may have multiple air outlets 232a, which are arranged at equal angular intervals along the circumference of the end air tube 232.

[0077] When the airflow passes through the gap between the liquid guide 222 and the air guide tube 23, it carries away some heat, causing a local temperature drop in the heating element 223. If the airflow velocity is uneven within the gap, the temperature distribution within the gap will be uneven, affecting the atomization effect. By arranging multiple air outlets 232a circumferentially, the airflow can be more symmetrical during the suction process, and the airflow velocity distribution within the gap is more uniform, which is beneficial to improving the atomization effect.

[0078] like Figure 4 As shown, the inlet of the first air inlet 2311a is located outside the inner wall of the liquid guide 222. That is, the orthographic projection of the inlet of the first air inlet 2311a onto the reference plane is outside the orthographic projection of the inner wall of the liquid guide 222 onto the reference plane, where the reference plane is a plane perpendicular to the axis of the first air pipe 231. The orthographic projection of the inner wall of the liquid guide 222 onto the reference plane can be a circle, and the orthographic projection of the inlet of the first air inlet 2311a onto the reference plane is located outside this circle.

[0079] When the aerosol generating device is tilted or laid down, such as horizontally, the liquid in the first air tube 231 can flow back to the atomizing channel 220a through the first air inlet 2311a. Since the inlet of the first air inlet 2311a is located on the outer side of the inner wall of the liquid guide 222, the liquid flowing out from the first air inlet 2311a is more likely to flow to the end face of the liquid guide 222 and be absorbed by the liquid guide 222, rather than flowing along the outer wall of the first air tube 231 to the end air tube 232.

[0080] As an example, the outer wall of the first trachea 231 has a protrusion, the first air inlet 2311a is located on the protrusion, and the entrance of the first air inlet 2311a is located on the surface of the protrusion away from the outer wall of the first trachea 231.

[0081] In some examples, the first trachea 231 may have multiple first air inlets 2311a, i.e., two or more first air inlets 2311a. The multiple first air inlets 2311a may be arranged at equal angular intervals along the circumference of the first trachea 231.

[0082] By arranging multiple first air inlets 2311a at equal angular intervals, the aerosol generating device can be tilted or laid down in different directions, and the liquid in the first air pipe 231 can also flow out through the first air inlet 2311a under the action of gravity.

[0083] As an example, the first trachea 231 may have two first air inlets 2311a, which are arranged symmetrically at the center.

[0084] like Figure 4As shown, the inner wall of the first trachea 231 has an annular stepped surface 231a, and the first air inlet 2311a is located on the side of the annular stepped surface 231a away from the end trachea 232.

[0085] The airflow entering the first air tube 231 from the first air inlet 2311a contains aerosol. Some of this aerosol may condense on the inner wall of the first air tube 231. During the use of the aerosol generating device, the nozzle of the atomizer 200 is usually facing upwards. The condensate formed on the inner wall of the first air tube 231 will gradually flow towards the end air tube 232 under gravity. By providing an annular stepped surface 231a, the condensate formed on the inner wall of the first air tube 231 is more likely to accumulate near the annular stepped surface 231a on the side away from the end air tube 232 under gravity. When the aerosol generating device is tilted or laid down, such as horizontally, the condensate accumulated at the annular stepped surface 231a can flow out more quickly through the first air inlet 2311a and into the atomizing core 22, where it is absorbed by the liquid guide 222, facilitating the discharge of the condensate formed in the first air tube 231.

[0086] As an example, the edge of the first air inlet 2311a is tangent to the annular stepped surface 231a. That is, the distance between the edge of the first air inlet 2311a and the annular stepped surface 231a can be 0.

[0087] The edge of the first air inlet 2311a is arranged to be tangent to the annular step surface 231a, so that when the aerosol generating device is laid down, the condensate accumulated at the annular step surface 231a can be discharged more fully from the first air inlet 2311a, reducing the amount of condensate remaining in the first air pipe 231.

[0088] In this example, the first air inlet 2311a is circular. In other possible implementations, the first air inlet 2311a can also be rectangular, with the edge of the rectangular first air inlet 2311a being tangent to the annular step surface 231a, that is, one side of the rectangular first air inlet 2311a can be flush with the annular step surface 231a.

[0089] like Figure 4 As shown, the first trachea 231 includes a first tube body 2311 and a second tube body 2312. The inner diameter of the first tube body 2311 is larger than the inner diameter of the second tube body 2312; one end of the first tube body 2311 is coaxially connected to one end of the second tube body 2312, forming an annular stepped surface 231a on the end face of the second tube body 2312; the other end of the second tube body 2312 is closed.

[0090] A first trachea 231 is formed by connecting a first tube 2311 and a second tube 2312 with different inner diameters. The end faces of the first tube 2311 and the second tube 2312 do not coincide. The end face of the second tube 2312 is at least partially located inside the first tube 2311, thereby forming an annular stepped surface 231a.

[0091] In some examples, the inner diameter of the first tube 2311 may be smaller than the outer diameter of the second tube 2312, and the first tube 2311 and the second tube 2312 are connected by an end face.

[0092] In other examples, the inner diameter of the first tube 2311 may be greater than or equal to the outer diameter of the second tube 2312. The first tube 2311 may be connected to a flange extending radially outward from the end of the second tube 2312.

[0093] Figure 5 This is a schematic diagram of the structure of an atomizing component provided in an embodiment of this application, as shown below. Figure 5 As shown, compared to Figure 4 The example shown, Figure 5 In the example shown, the air duct 23 also includes a second air duct 233, which is inserted into the second end of the first air duct 231. The outer wall of the second air duct 233 is connected to the second end of the first air duct 231, and the gap between the second air duct 233 and the first air duct 231 connects the second air duct 233 and the first air inlet 2311a.

[0094] The end of the second air tube 233 away from the end air tube 232 is used to connect to the mouthpiece 230 of the atomizer 200.

[0095] For example, the first trachea 231 and the second trachea 233 can be arranged coaxially, and an annular gap is formed between the first trachea 231 and the second trachea 233.

[0096] During atomization, air can enter the end air tube 232, and then enter the atomizing core 22 through the air outlet 232a on the side wall of the end air tube 232, where it mixes with the generated aerosol. The mixed airflow can then enter the gap between the second air tube 233 and the first air tube 231 through the first air inlet 2311a on the side wall of the first air tube 231, and then enter the second air tube 233 before flowing out.

[0097] When the aerosol generating device is tilted at a large angle, such as when it is inverted and the nozzle 230 is facing downwards, the liquid remaining in the first air tube 231 will flow along the inner wall of the first air tube 231 towards the second end of the first air tube 231. By providing a second air tube 233 in the first air tube 231, and connecting the outer wall of the second air tube 233 to the second end of the first air tube 231, the liquid in the first air tube 231 is less likely to flow out from the outlet of the atomization channel 220a in this situation, thus reducing the risk of liquid leakage from the nozzle 230.

[0098] like Figure 5 As shown, the first air inlet 2311a is opposite to the outer wall of the second air tube 233. That is, one end of the second air tube 233 extends to the side of the first air inlet 2311a near the end air tube 232. This makes it less likely for condensate formed inside the first air tube 231 to flow to the nozzle 230 through the second air tube 233.

[0099] During the operation of the aerosol generating device, the airflow enters the first air pipe 231 through the first air inlet 2311a, then enters the second air pipe 233 through the annular space between the first air pipe 231 and the second air pipe 233, and finally flows out from the first air pipe 231. In this process, the airflow undergoes a reversal within the air guide pipe 23, resulting in a longer flow path. This allows the airflow to be heated by the atomizing core 22 for a longer period, and also enables the airflow to be heated more thoroughly.

[0100] like Figure 5 As shown, the second trachea 233 is closed at one end near the end trachea 232. The side wall of the second trachea 233 has a second air inlet 233a, which is located on the side of the first air inlet 2311a near the end trachea 232.

[0101] During use, some of the liquid formed in the first trachea 231 may accumulate at the closed end of the first trachea 231 under the influence of gravity. If the accumulated liquid reaches a certain amount, it may exceed the end of the second trachea 233 near the end trachea 232, causing the end of the second trachea 233 to be submerged in liquid. By closing the end of the second trachea 233 near the end trachea 232 and providing a second air inlet 233a on the side wall of the second trachea 233, the risk of the second air inlet 233a being submerged and blocked by liquid can be reduced.

[0102] As an example, the second air pipe 233 may have multiple second air inlets 233a, which are arranged at equal angular intervals along the circumference of the second air pipe 233.

[0103] Since the aerosol generator is typically not completely upright when used by a user, but rather tilted at a certain angle, the second air pipe 233 is also tilted. By arranging multiple second air inlets 233a at equal angular intervals along the circumference of the second air pipe 233, even if a large amount of liquid accumulates in the first air pipe 231, causing some of the second air inlets 233a to be blocked, airflow can still enter the second air pipe 233 through the remaining second air inlets 233a, ensuring unobstructed airflow.

[0104] Figure 6 This is a schematic diagram of the structure of an atomizer provided in an embodiment of this application, as shown below. Figure 6 As shown, the atomizer 200 includes a liquid reservoir 210 and an atomizing assembly 220. The liquid reservoir 210 is used to store the aerosol matrix. The atomizing assembly 220 can be... Figures 3-5 Any of the atomizing components 220 shown. The atomizing component 220 is located in the liquid storage component 210 and is used to heat the aerosol matrix to form an aerosol.

[0105] like Figure 6 As shown, the liquid storage assembly 210 includes a liquid tank housing 211 and a base 212. The base 212 has a groove 212b opposite to the atomizing assembly 220. This groove 212b can be used to collect any aerosol matrix or condensate that may leak into the base 212, thus reducing the risk of liquid leakage to the outside of the atomizer 200 even if a leak occurs in the atomizing assembly 220. The base 212 may also have an air inlet 212a, which communicates with the end air pipe 232.

[0106] like Figure 6 As shown, the liquid storage assembly 210 also includes a seal 213, which is located on the side of the base 212 near the atomizing assembly 220. The seal 213 can seal the gap between the liquid tank housing 211 and the base 212, and can also seal the gap between the atomizing core 22 and the base 212, thereby improving the sealing performance of the liquid tank.

[0107] This application also provides an aerosol generating device, which includes a power supply component and, for example, a power supply component and, as described in the embodiments, an aerosol generating device. Figure 6 The atomizer 200 is shown. The power supply assembly 100 is used to supply power to the atomizing assembly 220.

[0108] In some examples, the power supply assembly 100 is detachably connected to the atomizer 200. Because the power supply assembly 100 is detachably connected to the atomizer 200, it is easy to replace the atomizer 200.

[0109] In other examples, the power supply assembly 100 and the atomizer 200 may be fixedly connected. For example, the housing portion of the power supply assembly 100 and the liquid tank housing 211 of the atomizer 200 are integrally formed.
