Description

Technical Field

[0001] The embodiments of the present application relate to the field of atomization technology, and specifically to a nebulizer and an aerosol generating device. Background Art

[0002] The aerosol generating device is used to generate aerosol for the user to inhale.

[0003] The aerosol-generating device comprises a main storage chamber, an additional storage chamber, and an atomizing core. The atomizing core absorbs aerosol-generating substrate from the main storage chamber and converts the substrate into aerosol. When the aerosol-generating substrate in the main storage chamber is consumed to a certain extent, the aerosol-generating substrate stored in the additional storage chamber enters the main storage chamber to replenish it, thereby extending the service life of the aerosol-generating device.

[0004] In related art, aerosol-generating devices also include a ventilation channel that connects the main storage chamber with the exterior of the aerosol-generating device. This allows outside air to enter the additional storage chamber through the ventilation channel and the main storage chamber, allowing the aerosol-generating substrate in the additional storage chamber to flow out. A liquid reservoir is provided within the main storage chamber to reduce the risk of the aerosol-generating substrate flowing through the ventilation channel into the outlet channel and overflowing from the aerosol-generating device.

[0005] Due to the uneven size and distribution of pores in the liquid storage component, when external gas enters the main storage cavity and passes through different areas of the liquid storage component, it encounters different resistances from the fibers of the liquid storage component and the aerosol generating matrix in the liquid storage component, resulting in poor airflow and also making the process of the aerosol generating matrix stored in the additional storage cavity entering the main storage cavity unstable.

DETAILED DESCRIPTION

[0037] It should be noted that, in the absence of conflict, the technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the embodiments of the present application and should not be regarded as an improper limitation on the embodiments of the present application.

[0038] In the description of the embodiments of the present application, the orientation or position relationship of the "first direction" is based on the attached Figure 3 、 Figure 5 、 Figure 6 and Figure 10 The orientation or position relationship shown; the orientation or position relationship of the "second direction" is based on the attached Figure 7 and Figure 8 It should be understood that these directional terms are only used to facilitate the description of the embodiments of the present application and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the embodiments of the present application.

[0039] The present invention provides an atomizer 10 for use in an aerosol generating device. The atomizer 10 can convert an aerosol-generating substrate into an aerosol for inhalation by a user. The aerosol generating device also includes an additional oil tank having an additional storage chamber 20a for storing the aerosol-generating substrate.

[0040] See Figures 1 to 5 The atomizer 10 includes an atomizing core 11 , a liquid storage component 12 and a mounting assembly 13 .

[0041] The atomizer core 11 has an atomizer cavity 11a. After the atomizer core 11 contacts the aerosol-generating substrate, the aerosol-generating substrate can be converted into aerosol by heating or other means. The aerosol enters the atomizer cavity 11a and exits the atomizer core 11 for inhalation by the user.

[0042] It is understandable that when a user inhales aerosol using the atomizer 10, the outlet of the atomization chamber 11a is connected to the user's mouth through a channel in the aerosol generating device, so that the aerosol enters the user's mouth through the negative pressure generated by the user's inhalation.

[0043] At least a portion of the atomizer core 11 is spaced from the inner wall of the mounting cavity 13c to form a primary storage cavity 13f. The primary storage cavity 13f is used to store an aerosol-generating substrate. The aerosol-generating substrate in the primary storage cavity 13f contacts the atomizer core 11, enabling the atomizer core 11 to convert the aerosol-generating substrate into aerosol.

[0044] The aerosol-generating substrate is a liquid fluid.

[0045] The atomizing chamber 11a is isolated from the main storage chamber 13f so that the aerosol generating substrate in the main storage chamber 13f is difficult to enter the atomizing chamber 11a without being converted into aerosol, thereby reducing the probability of the aerosol generating substrate directly entering the user's mouth.

[0046] The liquid storage element 12 is in fluid communication with the atomizer core 11 , which means that the aerosol-generating substrate absorbed and stored in the liquid storage element 12 can flow to the atomizer core 11 .

[0047] The liquid storage member 12 has a plurality of pores. After the liquid storage member 12 comes into contact with the aerosol generating matrix, the aerosol generating matrix can be absorbed by the liquid storage member 12 and stored in the space within the pores through capillary action. At least some of the pores are connected to each other so that the aerosol generating matrix can pass through the liquid storage member 12 and be transported to the atomizer core 11 in contact with the liquid storage member 12. In this way, after the aerosol generating matrix on the atomizer core 11 is consumed to a certain extent, the aerosol generating matrix can be replenished to the atomizer core 11 through the liquid storage member 12. In addition, the absorption and storage of the aerosol generating matrix by the liquid storage member 12 reduces the probability of the atomizer core 11 being immersed in the aerosol generating matrix, reduces the excessive aerosol generating matrix absorbed by the atomizer core 11 and reduces the concentration of the generated aerosol, which is conducive to improving the user experience.

[0048] The liquid inlet channel 13 a connects the main storage chamber 13 f and the additional storage chamber 20 a , so that the aerosol-generating substrate in the additional storage chamber 20 a enters the main storage chamber 13 f and is absorbed by the liquid storage member 12 , and then supplied to the atomizer core 11 through the liquid storage member 12 .

[0049] Air outside the nebulizer 10 can enter the liquid inlet channel 13a through the ventilation channel 13b and then enter the additional storage chamber 20a. This allows air outside the nebulizer 10 to be replenished into the additional storage chamber 20a after the aerosol-forming substrate in the additional storage chamber 20a flows out of the additional storage chamber 20a, thereby reducing the adverse effect of negative pressure within the additional storage chamber 20a on the outflow of the aerosol-forming substrate.

[0050] The ventilation channel 13 b and the installation cavity 13 c are isolated from each other, so that the airflow in the ventilation channel 13 b will not directly pass through the installation cavity 13 c and then enter the liquid inlet channel 13 a , and the airflow will not pass through the liquid storage component 12 .

[0051] In the atomizer 10 in the embodiment of the present application, the flow of air in the ventilation channel 13b is less likely to be blocked by the liquid storage component 12, thereby reducing the obstruction of the air flow due to the structure of the liquid storage component 12 itself and the absorbed aerosol generating matrix, which is conducive to timely replenishment of air into the additional storage chamber 20a, so that the aerosol generating matrix in the additional storage chamber 20a can enter the main storage chamber 13f in a timely manner, reducing the probability of dry burning of the atomizer 10 and improving user experience.

[0052] It is understandable that the pores of the liquid storage member 12 can be macroscopically discernible to the naked eye or microscopically invisible to the naked eye, as long as they meet the requirements of absorbing aerosols to generate a matrix through capillary action and allowing airflow to pass through.

[0053] The specific form of the liquid storage member 12 is not limited, for example, cotton wool, sponge, a fiber structure woven and twisted by chemical fibers such as polyester and nylon.

[0054] In some embodiments, see Figures 3 to 5 The mounting assembly 13 includes a shell 131 and a partition assembly 132. A accommodating chamber 131a is provided in the shell 131. The accommodating chamber 131a is open on one side along the first direction to form an installation opening for the partition assembly 132 to enter and exit. The partition assembly 132 is provided with an installation chamber 13c. At least part of the inner wall of the accommodating chamber 131a is separated from the partition assembly 132 to form at least part of the ventilation channel 13b.

[0055] During assembly of mounting assembly 13, after partition assembly 132 is inserted from the mounting opening into accommodating cavity 131a to the predetermined mounting position, at least a portion of the inner wall of accommodating cavity 131a and at least a portion of the surface of partition assembly 132 naturally form at least a portion of ventilation channel 13b. In other words, at least a portion of ventilation channel 13b is not located solely within partition assembly 132 or within housing 131, but rather is formed by both.

[0056] In this way, it is beneficial to reduce the need to set up additional channels in the parts of the shell 131 and the partition assembly 132 to form the ventilation channel 13b, which is beneficial to simplifying the structure of the shell 131 and the partition assembly 132 and reducing the manufacturing costs of both; at least a part of the ventilation channel 13b is formed simultaneously in the process of installing the installation assembly 13 into the installation cavity 13c, which is beneficial to simplify the overall assembly steps of the atomizer 10 and improve assembly efficiency.

[0057] In some embodiments, the housing 131 is made of engineering plastic material, and the opening direction of the installation opening is the mold ejection direction during the manufacturing process of the housing 131 .

[0058] In some embodiments, see Figure 3 and Figure 4 The ventilation channel 13b includes a first sub-channel 13d. The portion of the inner wall of the accommodating chamber 131a away from the installation port along the first direction is spaced from the partition component 132 along the first direction to form the first sub-channel 13d. The liquid inlet channel 13a is connected to the first sub-channel 13d.

[0059] The partition component 132 is loaded into the accommodating cavity 131a along the first direction and moves along the first direction until the partition component 132 abuts against the inner wall of the accommodating cavity 131a along the first direction away from the installation port, thereby achieving the positioning of the partition component 132 along the first direction and forming the first sub-channel 13d at the same time.

[0060] It can be understood that at least a portion of the liquid inlet channel 13a is located on a side of the atomizer 10 away from the mounting opening along the first direction so as to communicate with the first sub-channel 13d.

[0061] The specific method of forming the first sub-channel 13d is not limited. It can be that the inner wall of the accommodating chamber 131a along the first direction away from the installation port is provided with a through groove, the through groove is open toward the side of the installation port, and the partition component 132 is covered at the opening of the through groove to form at least part of the first sub-channel 13d; it can be that the partition component 132 is provided with a through groove on one side surface along the first direction, the through groove is open toward the inner wall of the accommodating chamber 131a along the first direction away from the installation port, and the accommodating chamber 131a is covered at the opening of the through groove to form at least part of the first sub-channel 13d; it can also be that the inner wall of the accommodating chamber 131a along the first direction away from the installation port and the surface of the partition component 132 along the first direction are both provided with channels, the two through grooves are opposite to each other and open along the first direction, and the two through grooves are connected to each other along the first direction to form at least part of the first sub-channel 13d.

[0062] In some embodiments, see Figures 3 to 5The liquid inlet channel 13a includes a first liquid inlet hole 131b and a second liquid inlet hole 132a. The first liquid inlet hole 131b passes through the shell 131 and is located on the side of the accommodating cavity 131a away from the mounting port along the first direction. The partition component 132 is provided with a second liquid inlet hole 132a. The second liquid inlet hole 132a connects the first liquid inlet hole 131b with the main storage cavity 13f. The connecting position of the first sub-channel 13d and the liquid inlet channel 13a is located at the connecting point of the first liquid inlet hole 131b and the second liquid inlet hole 132a.

[0063] In this way, the connection position between the first sub-channel 13d and the liquid inlet channel 13a is facilitated to be away from the liquid storage component 12 in the main storage cavity 13f, further reducing the probability of the liquid storage component 12 interfering with the airflow in the first sub-channel 13d, which is conducive to improving the airflow efficiency.

[0064] In some embodiments, see Figure 3 and Figure 4 The first liquid inlet 131b and the second liquid inlet 132a both extend along the first direction, and the main storage chamber 13f is located on the side of the second liquid inlet 132a that is away from the first liquid inlet 131b along the first direction. This facilitates direct flow of aerosol-generating substrate from the additional storage chamber 20a into the main storage chamber 13f along the first direction, thereby ensuring timely replenishment of the aerosol-generating substrate.

[0065] In some embodiments, see Figure 3 and Figure 4 In a projection plane perpendicular to the first direction, the projection of the second liquid inlet 132a lies within the projection of the liquid storage element 12. This facilitates the direct entry of the aerosol-generating substrate flowing out of the second liquid inlet 132a into the liquid storage element 12 for timely absorption. Furthermore, it facilitates the inner wall of the main storage chamber 13f to constrain the position of the liquid storage element 12, reducing the probability of a portion of the liquid storage element 12 entering the first liquid inlet 131b or the second liquid inlet 132a and blocking the outlet of the first subchannel 13d.

[0066] It is understandable that the aerosol-generating substrate in the liquid inlet channel 13a may enter the first sub-channel 13d through the communication position between the first sub-channel 13d and the liquid inlet channel 13a.

[0067] In some embodiments, see Figure 6 and Figure 8 , the first sub-channel 13d extends in a zigzag manner.

[0068] In this way, on the one hand, it is beneficial to increase the length of the first sub-channel 13d, and thus increase the volume of the first sub-channel 13d, so that more aerosol generating matrix can be stored in the first sub-channel 13d, reducing the probability of the aerosol generating matrix flowing out of the nebulizer 10 from the ventilation channel 13b; on the other hand, the aerosol generating matrix flowing in the first sub-channel 13d needs to constantly change its flow direction, which is beneficial to slow down its flow speed, and also reduces the probability of the aerosol generating matrix flowing out of the nebulizer 10 from the ventilation channel 13b.

[0069] In some embodiments where the atomizer core 11 has an atomizer cavity 11a, see Figure 3 and Figure 5 The shell 131 is provided with a penetrating air outlet 131 c, and the air outlet 131 c is communicated with the atomization chamber 11 a.

[0070] The air outlet 131 c communicates with the outside of the atomizer 10 and the atomizing chamber 11 a , so that the aerosol in the atomizing chamber 11 a can be discharged out of the atomizer 10 through the air outlet 131 c .

[0071] In some embodiments, see Figure 3 and Figure 5 The air outlet hole 131 c penetrates the shell 131 along the first direction, so that the air outlet hole 131 c and the accommodating cavity 131 a are formed at one time during the demolding process of manufacturing the shell 131 .

[0072] In some embodiments, see Figure 7 and Figure 8 The air outlet 131c and the liquid inlet channel 13a are located on the same side of the atomizer 10 along the first direction, the outlet of the first sub-channel 13d connected to the liquid inlet channel 13a and the inlet of the first sub-channel 13d are located on opposite sides of the air outlet 131c along the second direction, and the first direction intersects with the second direction.

[0073] That is to say, the first sub-channel 13d needs to bypass the air outlet 131c to be connected to the liquid inlet channel 13a.

[0074] This is beneficial for increasing the length of the first sub-channel 13d, thereby increasing the volume of the first sub-channel 13d, so that more aerosol-generating substrate can be stored in the first sub-channel 13d, reducing the probability of the aerosol-generating substrate flowing out of the nebulizer 10 from the ventilation channel 13b.

[0075] In some embodiments, the first direction is perpendicular to the second direction.

[0076] In some embodiments, see Figure 3 、 Figure 7 and Figure 8There are two liquid inlet channels 13a and two first sub-channels 13d. The two liquid inlet channels 13a are located on opposite sides of the air outlet 131c along the second direction. The inlet of the first sub-channel 13d is located on the side of one liquid inlet channel 13a away from the air outlet 131c along the second direction, and its outlet is connected to the other liquid inlet channel 13a.

[0077] In this way, on the one hand, the length of the first sub-channel 13d can be further increased; on the other hand, the entrance of the first sub-channel 13d is not located between the air outlet 131c and the liquid inlet channel 13a, reducing the probability of the partition component 132 blocking the entrance of the first sub-channel 13d.

[0078] In some embodiments, see Figures 3 to 5 The ventilation channel 13b includes a second sub-channel 13e, and at least part of the inner wall of the accommodating cavity 131a and the partition component 132 are spaced perpendicular to the first direction to form the second sub-channel 13e.

[0079] This helps reduce the friction between the partition assembly 132 and the inner wall of the accommodating cavity 131 a, thereby improving the convenience of installing the partition assembly 132.

[0080] The specific structural form of the partition component 132 is not limited.

[0081] For example, see Figure 3 and Figure 5 The partition assembly 132 includes a first seal 1321, a second seal 1322 and a partition 1323. The partition 1323 is provided with a cavity extending along a first direction. The first seal 1321 and the second seal 1322 are respectively sealed at the opening of the cavity to enclose and form an installation cavity 13c. The inner wall of the accommodating cavity 131a is separated from the partition 1323 to form a second sub-channel 13e.

[0082] In this way, during the assembly of the partition assembly 132, the liquid storage component 12 and the atomizer core 11 can be first installed into the cavity through the open position of the cavity, and then the open position of the cavity is closed by the first sealing component 1321 and the second sealing component 1322, so that the liquid storage component 12 and the atomizer core 11 can be installed into the accommodating cavity 131a together with the partition assembly 132, thereby simplifying the assembly steps of the atomizer 10.

[0083] The first sealing member 1321 and the second sealing member 1322 are both made of elastic material, so that they can maintain a sealed fit with the partition 1323 through elastic deformation, thereby reducing the probability of leakage of the aerosol generating matrix.

[0084] The elastic material used by the first sealing member 1321 and the second sealing member 1322 may be rubber, silicone, or the like.

[0085] In some embodiments with a first sub-channel 13d, see Figure 4 An air flow groove 131d is provided on the inner wall of the accommodating cavity 131a along the first direction away from the installation port. The air flow groove 131d is open toward the side of the installation port. The first sealing member 1321 covers the opening of the air flow groove 131d to form a first sub-channel 13d. The second sub-channel 13e is connected to the first sub-channel 13d, and the liquid inlet channel 13a is connected to the first sub-channel 13d.

[0086] The inner wall of the air flow groove 131d is formed by the structure of the shell 131, and its structural strength is higher than the structural strength of the elastic material of the first seal 1321. In this way, when negative pressure is generated in the first sub-channel 13d, the deformation of the inner wall of the first sub-channel 13d under the action of negative pressure is reduced, so as to improve the efficiency of external air entering the first sub-channel 13d and timely balance the air pressure of the additional storage chamber 20a and the external air pressure.

[0087] In some embodiments, see Figure 3 The atomizing chamber 11 a extends along the first direction, and the atomizing core 11 is sandwiched between the first sealing member 1321 and the second sealing member 1322 along the first direction.

[0088] In this way, the first seal 1321 and the second seal 1322 are used to fix the position of the seal. At the same time, the atomization chamber 11a and the main storage chamber 13f are separated by the first seal 1321 and the second seal 1322, thereby reducing the probability of leakage of the aerosol generation matrix.

[0089] In some embodiments, see Figure 3 and Figure 4 The ventilation channel 13b includes a first air flow hole 1321a, and the first sealing member 1321 is sealed and fitted with the inner wall of the accommodating cavity 131a perpendicular to the first direction. The first air flow hole 1321a is provided on the first sealing member 1321 and connects the first sub-channel 13d and the second sub-channel 13e.

[0090] In this way, on the one hand, it is beneficial to limit and guide the movement of the partition component 132 in the accommodating cavity 131a through the first sealing member 1321 and the inner wall of the accommodating cavity 131a; on the other hand, it improves the sealing effect and reduces the probability of the aerosol generating matrix leaking into the second sub-channel 13e.

[0091] The number of the first air flow holes 1321 a is not limited, and may be one or more.

[0092] In some embodiments, see Figure 3 and Figure 5The ventilation channel 13b includes a second air flow hole 1322a, and the second sealing member 1322 is sealed and fitted with the inner wall of the accommodating cavity 131a perpendicular to the first direction. The second air flow hole 1322a is provided on the second sealing member 1322 and connects the second sub-channel 13e with the outside of the atomizer 10.

[0093] In this way, on the one hand, it is beneficial to limit and guide the movement of the partition component 132 in the accommodating cavity 131a through the second sealing member 1322 and the inner wall of the accommodating cavity 131a; on the other hand, it improves the sealing effect and reduces the probability of the aerosol generating matrix leaking into the second sub-channel 13e.

[0094] The number of the second air flow holes 1322a is not limited, and can be one or more.

[0095] In some embodiments, the inlet of the second air flow hole 1322a forms the inlet of the ventilation channel 13b.

[0096] In some embodiments, see Figure 3 and Figure 4 , the first air flow holes 1321a extend along the first direction.

[0097] In some embodiments, see Figure 4 The first sealing member 1321 is provided with a first sealing protrusion 1321b protruding along the first direction. The first sealing protrusion 1321b is embedded in the cavity and sealed with the inner wall of the cavity perpendicular to the first direction.

[0098] In this way, on the one hand, the first sealing protrusion 1321b can play a guiding and positioning role, so that the relative position of the first sealing member 1321 and the partition 1323 can meet the design requirements during the installation process; on the other hand, it is beneficial to increase the contact area between the first sealing member 1321 and the partition 1323 and improve the sealing effect.

[0099] In some embodiments, see Figure 3 The second sealing member 1322 is provided with a second sealing protrusion 1322b protruding along the first direction. The second sealing protrusion 1322b is embedded in the cavity and sealed with the inner wall of the cavity perpendicular to the first direction.

[0100] In this way, on the one hand, the second sealing protrusion 1322b can play a guiding and positioning role, so that the relative position of the second sealing member 1322 and the partition 1323 can meet the design requirements during the installation process; on the other hand, it is beneficial to increase the contact area between the second sealing member 1322 and the partition 1323 and improve the sealing effect.

[0101] In some embodiments, see Figure 3The dimension of the portion of the second sealing protrusion 1322b embedded in the cavity along the first direction is not less than 2 mm (millimetres). That is, D1 ≥ 2 mm.

[0102] This is beneficial to increasing the contact area between the second sealing protrusion 1322 b and the partition 1323 , and improving the connection stability and sealing effect between the second sealing member 1322 and the partition 1323 .

[0103] The specific size of the portion of the second sealing protrusion 1322b embedded in the cavity along the first direction can be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, etc.

[0104] In the embodiment with the second liquid inlet hole 132a, see Figure 4 The second liquid inlet hole 132a is provided in the first sealing member 1321 .

[0105] In some embodiments, see Figure 3 and Figure 5 The atomizer 10 further includes a mounting cover 14, which is disposed at the mounting port. At least a portion of the mounting cover 14 is spaced from the partition assembly 132 along a first direction to form a guide space 14a. The ventilation channel 13b and the atomizing chamber 11a are both connected to the guide space 14a. The mounting cover 14 is provided with an air inlet hole 14b extending therethrough, which connects the guide space 14a with the outside of the atomizer 10.

[0106] External air enters the flow-guiding space 14a. On the one hand, the gas flows into the atomizing chamber 11a to carry the aerosol out of the atomizer 10 for the user to inhale. On the other hand, the aerosol-generating matrix overflowing from the liquid inlet channel 13a through the ventilation channel 13b can be stored in the flow-guiding space 14a to reduce the risk of leakage of the aerosol-generating matrix.

[0107] In some embodiments, see Figure 3 and Figure 5 The nebulizer 10 further includes a liquid absorbing member 15 , which is disposed in the flow guiding space 14 a and can absorb the aerosol-generating matrix.

[0108] In this way, even if the aerosol-generating substrate enters the flow guiding space 14a through the ventilation channel 13b, the liquid absorbing member 15 can absorb at least part of the aerosol-generating substrate, thereby further reducing the probability of the aerosol-generating substrate entering the atomization chamber 11a.

[0109] The absorbent element 15 is provided with pores therein to absorb the aerosol-generating substrate.

[0110] It is understandable that the pores of the absorbent element 15 can be macroscopically discernible to the naked eye or microscopically invisible to the naked eye, as long as they meet the requirements of absorbing aerosols to generate a matrix through capillary action and allowing airflow to pass through.

[0111] The specific form of the liquid-absorbing member 15 is not limited, for example, cotton wool, sponge, a fiber structure woven and twisted by chemical fibers such as polyester and nylon, etc.

[0112] It is understood that the aerosol generating substrate is wettable relative to the material of the liquid absorbing member 15 , so that the aerosol generating substrate is attached to or absorbed by the liquid absorbing member 15 .

[0113] In some embodiments where a liquid absorbing member 15 is provided, see Figure 5 and Figure 6 On a projection plane perpendicular to the first direction, the projection of the inlet of the ventilation channel 13b is located within the projection range of the absorbing member 15, so that the aerosol-generating substrate flowing out of the ventilation channel 13b can contact the absorbing member 15 as quickly as possible and be absorbed by the absorbing member 15.

[0114] In some embodiments, the liquid absorbing component 15 and the liquid storage component 12 have the same structure and material to simplify the manufacturing process.

[0115] The present invention also provides an aerosol generating device. Figure 9 and Figure 10 The aerosol generating device includes a storage component 20 and the atomizer 10 of any of the aforementioned embodiments. The storage component 20 is provided with an additional storage chamber 20a, which is connected to the liquid inlet channel 13a, and the ventilation channel 13b is connected to the outside of the aerosol generating device.

[0116] After the airflow enters the liquid inlet channel 13a through the ventilation channel 13b, it enters the additional storage chamber 20a, so that the aerosol generating substrate in the additional storage chamber 20a can enter the main storage chamber 13f, thereby replenishing the loss of the aerosol generating substrate in the main storage chamber 13f.

[0117] In some embodiments, the storage unit 20 is provided with an air outlet channel 20b, which is connected to the outlet of the atomization chamber 11a and to the outside of the aerosol generating device so as to be connected to the user's mouth during the user's inhalation process, so that the aerosol can enter the user's mouth.

[0118] The various embodiments / implementations of the present application can be combined with each other without causing any contradiction.

[0119] The above description is merely a preferred technical solution in the embodiments of the present application and is not intended to limit the scope of protection of the embodiments of the present application. For those skilled in the art, the embodiments of the present application may be modified and varied in various ways. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the embodiments of the present application shall be included in the scope of protection of the embodiments of the present application.
