The user sucks the aerosol generated by the main body assembly 1 by sucking the mouthpiece assembly 3.

[0074] In some embodiments, not shown, the aerosol-generating device comprises a plurality of mouthpiece assemblies, the plurality of mouthpiece assemblies being connected to the plurality of atomizers one-to-one so that the plurality of air inlets can be in fluid communication with the plurality of atomizers one-to-one.

[0075] In some embodiments, with reference to Figure 1 , the number of the mouthpiece assemblies 3 is less than the number of the atomizers, the first atomizer 11 and the second atomizer 12 share the same mouthpiece assembly 3.

[0076] In some embodiments, with reference to Figure 1 , the first atomizing member 112 and the second atomizing member 122 are configured to be able to independently communicate with the air inlet 31. So that the first atomizer 11 and the second atomizer 12 belong to the same airflow level and are not in upstream and downstream relationship in the airflow direction. Therefore, the aerosol generated by the first atomizer 11 can flow into the downstream air inlet 31 without passing through the second atomizer 12, and the aerosol generated by the second atomizer 12 can flow into the downstream air inlet 31 without passing through the first atomizer 11.

[0078] The power supply 13 can individually provide electrical power to any one of the first atomizer 11 and the second atomizer 12, so that the aerosol flowing into the air inlet 31 can be one of the first aerosol and the second aerosol.

[0079] In some embodiments, not shown, the air inlet can comprise a first air inlet and a second air inlet arranged separately. The first air inlet is used to fluidly communicate the first air guide tube, so that the first aerosol can be sequentially drawn by the user through the first air guide tube and the first air inlet; the second air inlet is used to fluidly communicate the second air guide tube, so that the second aerosol can be sequentially drawn by the user through the second air guide tube and the second air inlet.

After the mouthpiece assembly 3 is removed, a mounting port on the housing 14 is exposed, and then the first atomizer 11 and / or the second atomizer 12 can be taken out of the housing 14 through the mounting port, or a new first atomizer 11 and / or a new second atomizer 12 can be installed into the housing 14 through the mounting port.

By magnetically attracting the first magnetic member 15 to the second magnetic member 28, the mouthpiece assembly 3 is prevented from being rotated relative to the main body assembly or removed from the main body assembly in an unexpected manner, thereby helping to maintain the air inlet 31 in fluid communication with the first air guide pipe 113 or the second air guide pipe 123. At the same time, the magnetic attraction between the first magnetic member and the second magnetic member can cause the mouthpiece assembly 3 to tightly fit with the first atomizer 11 and the second atomizer 12 to prevent aerosol from leaking from the outlet end of the first air guide pipe 113 and the second air guide pipe 123.

[0083] The first magnetic member and the second magnetic member can each have a plurality, and the plurality of first magnetic members and the plurality of second magnetic members can be magnetically attracted one by one when the air inlet 31 is in fluid communication with the first air guide pipe 113 or the second air guide pipe 123.

[0084] It should be noted that the detachable connection of the mouthpiece assembly 3 with the housing 14 is optional and not mandatory, and in other embodiments, the mouthpiece assembly 3 can be non-removably connected to the housing 14 or the mouthpiece assembly 3 can be non-removably connected to the main body assembly 1.

Figure 1 The first air hole 115 is located upstream of the first air guide pipe 113 in the airflow direction, and when suction is applied, external air enters the first atomizer 11 through the first air hole 115 and then enters the first air guide pipe 113.

[0086] Further, the power supply 13 can also be arranged in the housing 14, the first atomizer 11 can be arranged between the mouthpiece assembly 3 and the power supply 13, and a first airflow passage 151 can be arranged between the power supply 13 and the inner wall of the housing 14, in the airflow direction, the first airflow passage 151 is located upstream of the first air hole 115, and when suction is applied, the air from the outside can flow into the first air hole 115 through the first airflow passage 151.

[0087] In some embodiments, the first atomizer 11 can be arranged in the airflow direction between the second air hole 125 and the second air guide tube 123, and the second air guide tube 123 can be arranged in the airflow direction between the second air hole 125 and the second air guide tube 123. Figure 1 The second atomizer 12 includes a second air hole 125, in the airflow direction, the second air hole 125 is located upstream of the second air guide tube 123, and when suction is applied, the air from the outside enters the second atomizer 12 through the second air hole 125, and then enters the second air guide tube 123.

[0088] Further, the second atomizer 12 can be arranged between the mouthpiece assembly 3 and the power supply 13, and a second airflow passage 152 can be arranged between the power supply 13 and the inner wall of the housing 14, in the airflow direction, the second airflow passage 152 is located upstream of the second air hole 125, and when suction is applied, the air from the outside can flow into the second air hole 125 through the second airflow passage 152.

[0089] In some embodiments, the adjustment assembly 2 is configured to be movable relative to the main body assembly 1 between a plurality of different holding positions, to adjust the electrical connection relationship between the first atomizer 11 or the second atomizer 12 and the power supply 13, so that when the adjustment assembly 2 is located in any one holding position, the power supply 13 provides electrical power to at least one of the first atomizer 11 and the second atomizer 12. Thus, when the adjustment assembly 2 is located in any one holding position, at least one of the first atomizer 11 and the second atomizer 12 can obtain electrical power to generate aerosol.

[0090] For convenience of description, define the total power provided by the power supply 13 to the first atomizer 11 and the second atomizer 12 as Q, when the adjustment assembly 2 is located in the holding position, the power supply 13 provides electrical power Q1 to the first atomizer 11, and the power supply 13 provides electrical power Q2 to the second atomizer 12, Q = Q1 + Q2, Q1 ≥ 0W, Q2 ≥ 0W.

[0091] In some embodiments, the adjustment assembly 2 is configured to be movable relative to the main body assembly 1 between a plurality of different holding positions, so that when the adjustment assembly 2 is located in at least two different holding positions, the power supply 13 provides different electrical power to the first atomizer 11. For example, when the adjustment assembly 2 is located in one of the holding positions, the power supply 13 provides electrical power Q1 to the first atomizer 11, Q1 ≥ 0W, when the adjustment assembly 2 is located in another holding position, the power supply 13 provides electrical power Q1' to the first atomizer 11, Q1' > Q1 ≥ 0W.

[0092] Therefore, the electrical power supplied by the power supply 13 to the first atomizer 11 can be changed by changing the holding position of the adjustment component 2, thereby adjusting the amount of the first atomizer 11 generated.

[0093] As a typical example, when the adjustment component 2 is in different holding positions, the power supply 13 provides different electrical power to the first atomizer 11.

[0094] In some embodiments, the power supply 13 provides the same electrical power to the second atomizer 12 when the adjustment component 2 is in different holding positions. Therefore, the electrical power supplied by the power supply 13 to the second atomizer 12 cannot be changed by altering the holding position of the adjustment component 2. In other words, Q1 can vary with the holding position of the adjustment component 2, but Q2 can remain the same regardless of whether the adjustment component 2 is in any holding position.

[0095] Alternatively, in some embodiments, the power supply 13 provides different electrical power to the second atomizer 12 when the adjustment component 2 is in at least two different holding positions. Therefore, the electrical power provided by the power supply 13 to the second atomizer 12 can be changed by altering the holding position of the adjustment component 2, thereby adjusting the amount of the second aerosol generated by the second atomizer 12. For example, when the adjustment component 2 is in one holding position, the electrical power Q2 provided by the power supply 13 to the second atomizer 12 is greater than or equal to 0 W; when the adjustment component 2 is in another holding position, the electrical power Q2′ provided by the power supply 13 to the second atomizer 12 is greater than Q2, i.e., Q2′>Q2≥0W.

[0096] Therefore, in one example, Q2 can vary depending on the holding position of the adjustment component 2; in other words, the power supply 13 provides different electrical power to the second atomizer 12 when the adjustment component 2 is in different holding positions. In one example, when the adjustment component 2 moves from one holding position to another, both the electrical power Q1 provided by the power supply 13 to the first atomizer 11 and the electrical power Q2 provided by the power supply 13 to the second atomizer 12 change. In one example, when the adjustment component 2 moves from one holding position to another, at least one of the electrical power Q1 provided by the power supply 13 to the first atomizer 11 and the electrical power Q2 provided by the power supply 13 to the second atomizer 12 changes.

[0097] In some embodiments, the total power Q provided by the power supply 13 to the first atomizer 11 and the second atomizer 12 remains unchanged when the adjustment assembly 2 is located at different holding positions, but the power Q1 provided by the power supply 13 to the first atomizer 11 changes with the change of the holding position where the adjustment assembly 2 is located, so that the power Q2 provided by the power supply 13 to the second atomizer 12 also changes with the change of the holding position where the adjustment assembly 2 is located, and the power provided by the power supply 13 to the first atomizer 11 and the second atomizer 12 is adjusted in the opposite direction when the adjustment assembly 2 moves from one holding position to another holding position. When the adjustment assembly 2 is located at one or more holding positions, Q1 can be equal to Q2. Of course, it is also possible that Q1 is not equal to Q2 when the adjustment assembly 2 is located at any holding position.

[0098] Further, the adjustment assembly 2 can move between and be held at 7 holding positions, and the corresponding relationship between Q1 and Q2 when the adjustment assembly 2 is located at different holding positions can be as shown in Table 1:

[0099] Table 1

[0100] Hold position 1 Hold position 2 Hold position 3 Hold position 4 Hold position 5 Hold position 6 Hold position 7 Q1 100％ 80％ 60％ 50％ 40％ 20％ 0 Q2 0 20％ 40％ 50％ 60％ 80％ 100％

[0101] When the adjustment assembly 2 is located at the holding position 1, the power supply 13 only provides power to the first atomizer 11 of the first atomizer 11 and the second atomizer 12, and Q1 = Q, or Q1 / Q = 1, Q2 / Q = 0. When the adjustment assembly 2 is located at the holding position 7, the power supply 13 only provides power to the second atomizer 12 of the first atomizer 11 and the second atomizer 12, and Q2 = Q, or Q1 / Q = 0, Q2 / Q = 1. When the adjustment assembly 2 is located at the holding position 2 to the holding position 6, the power supply 13 provides power to the first atomizer 11 and the second atomizer 12 at the same time. Among them, when the adjustment assembly 2 is located at the holding position 4, the power supply 13 provides the same power to the first atomizer 11 and the second atomizer 12, and Q1 = Q2 = Q / 2, or Q1 / Q = 0.5, Q2 / Q = 0.5.

[0102] In some embodiments, the total power Q provided by the power supply 13 to the first atomizer 11 and the second atomizer 12 changes when the adjustment assembly 2 is located at different holding positions. The power provided by the power supply 13 to the first atomizer 11 and the second atomizer 12 can be adjusted in opposite directions when the adjustment assembly 2 is moved from one holding position to another holding position, for example, Q and Q1 increase and Q2 decreases when the adjustment assembly 2 is moved from one holding position to another holding position. Of course, the power provided by the power supply 13 to the first atomizer 11 and the second atomizer 12 can also be adjusted in the same direction when the adjustment assembly 2 is moved from one holding position to another holding position, for example, Q, Q1 and Q2 all increase when the adjustment assembly 2 is moved from one holding position to another holding position.

[0103] In some embodiments, the body assembly 1 and the adjustment assembly 2 can be configured to be moved relative to each other, and the adjustment assembly 2 can be configured to be located at different holding positions when the adjustment assembly 2 is located at different holding positions, the second electrode group 16 is electrically connected to different first electrode groups 21, thereby adjusting the electrical connection relationship between the first atomizer 11 or the second atomizer 12 and the power supply 13, and further adjusting the power provided by the power supply 13 to the first atomizer 11 and / or the second atomizer 12. Figure 3 Figure 5 In some embodiments, one of the body assembly 1 and the adjustment assembly 2 includes a first electrode group 21, and the other includes a second electrode group 16, the first electrode group 21 has a plurality of; the adjustment assembly 2 is configured to be electrically connected to different first electrode groups 21 when located at different holding positions, thereby adjusting the electrical connection relationship between the first atomizer 11 or the second atomizer 12 and the power supply 13, and further adjusting the power provided by the power supply 13 to the first atomizer 11 and / or the second atomizer 12. Therefore, the holding position of the adjustment assembly 2 can be changed by moving the adjustment assembly 2 relative to the body assembly 1, thereby changing the first electrode group 21 electrically connected to the second electrode group 16, and further changing the power provided by the power supply 13 to the first atomizer 11 and / or the second atomizer 12.

[0104] When the second electrode group 16 is electrically connected to one of the first electrode groups 21, the second electrode group 16 can be electrically connected to the power supply 13 through the first electrode group 21, or the first electrode group 21 can be electrically connected to the power supply 13 through the second electrode group 16.

[0105] Further, with reference to Figure 7 , the aerosol generating device 100 further includes a processor 17, the first electrode group 21 includes two first electrodes 211, the two first electrodes 211 in different first electrode groups 21 have different impedances, and the processor 17 is configured to collect an electrical parameter of the first electrode group 21 electrically connected to the second electrode group 16, and control the power provided by the power supply 13 to the first atomizer 11 and / or the second atomizer 12 according to the electrical parameter.

[0106] ​The electrical parameter of the first electrode group 21 is associated with the impedance between the two first electrodes 211 in the first electrode group 21. The electrical parameter can be the voltage between the two first electrodes 211 in the first electrode group 21, can be the potential of any first electrode 211 in the first electrode group 21, can be the current flowing through any first electrode 211 in the first electrode group 21, and / or can be the resistance between the two first electrodes 211 in the first electrode group 21, etc.

[0107] The two first electrodes 211 in different first electrode groups 21 have different impedances, so that the electrical parameter is different when the second electrode group 16 is electrically connected to different first electrode groups 21. The processor 17 identifies the first electrode group 21 to which the second electrode group 16 is electrically connected by identifying the electrical parameter.

[0108] Correspondingly, the second electrode group 16 can include two second electrodes 161, and when the second electrode group 16 is electrically connected to one of the first electrode groups 21, the two second electrodes 161 are respectively electrically connected to the two first electrodes 211 in the first electrode group 21.

[0109] In some embodiments, the first electrode 211 and the second electrode 161 are electrically connected by abutting each other, so as to facilitate the separation of the second electrode 161 from the first electrode 211 to which the second electrode 161 is electrically connected and facilitate the electrical connection of the second electrode 161 to the first electrode 211 in the next first electrode group 21.

[0110] In order to improve the stability of the electrical connection between the first electrode 211 and the second electrode 161, at least one of the first electrode 211 and the second electrode 161 is provided with elasticity, so that the first electrode 211 can elastically abut the second electrode 161. Preferably, the direction in which the adjustment assembly 2 moves relative to the main body assembly 1 is perpendicular to the direction in which the first electrode 211 and / or the second electrode 161 elastically deforms.

[0111] For example, the aerosol-generating device 100 includes a first circuit board 22, the first electrode 22 includes a metal sheet laid on the first circuit board 22, and the second electrode 161 has elasticity, for example, the second electrode 161 can include a spring needle or a spring sheet.

[0112] In some embodiments, with reference to Figures 4-6 The adjustment assembly 2 includes the first electrode group 21, the main body assembly 1 includes the second electrode group 16, the first circuit board 22 is a component of the adjustment assembly 2, and the first electrode group 21 is arranged on the first circuit board 22, so that the first circuit board 22 and the first electrode group 21 can move relative to the main body assembly 1 and the second electrode group 16.

[0113] For example, as Figure 7In the shown embodiment, the adjustment assembly 2 further comprises a plurality of identity resistors 23 with different resistance values, at least one identity resistor 23 is connected between two first electrodes 211 of at least some of the first electrode groups 21, so that the total resistance values of the identity resistors 23 connected between two first electrodes 211 of different first electrode groups 21 are different. The identity resistors 23 are arranged on the first circuit board 22.

[0114] Two first electrodes 211 of one first electrode group 21 of the plurality of first electrode groups 21 can be directly electrically connected, or electrically connected through a conductor with a small resistance value. In other words, the resistance value of the identity resistor 23 between two first electrodes 211 of one first electrode group 21 can be infinitely close to 0Ω.

[0115] Two first electrodes 211 of one first electrode group 21 of the plurality of first electrode groups 21 can be open circuit, so that the two first electrodes 211 are not electrically connected, so that the resistance value between the two first electrodes 211 is infinitely large. In other words, the resistance value of the identity resistor 23 between two first electrodes 211 of one first electrode group 21 can be infinitely close to ∞Ω.

[0116] Further, the main body assembly 1 comprises a second circuit board 18 electrically connected with the power supply 13, the second electrode group 16 is electrically connected with the second circuit board 18, and the processor 17 is arranged on the second circuit board 18. The first circuit board 22 and the second circuit board 18 are independent of each other, so that the first circuit board 22 can move relative to the second circuit board 18.

[0117] In some embodiments, with reference to Figure 1 , the mouthpiece assembly 3 is arranged at the proximal end of the main body assembly 1, and the adjustment assembly 2 is arranged at the distal end of the main body assembly 1, so that the main body assembly 1 is located between the mouthpiece assembly 3 and the adjustment assembly 2.

[0118] The aerosol generating device 100 further comprises an end cap 4, and the main body assembly 1 further comprises a support 19, the end cap 4 supports the adjustment assembly 2 at the distal end of the adjustment assembly 2, and the end cap 4 is fixedly connected with the support 19 to prevent the adjustment assembly 2 from being separated from the main body assembly 1.

[0119] In some embodiments, with reference to Figure 1 and Figure 2 , the power supply 13 is a rechargeable power supply, and the main body assembly 1 further comprises a charging port 20, the charging port 20 is fixed on the support 19, and the end cap 4 is provided with a through hole 41 corresponding to the charging port 20. The charging port 20 can be exposed through the through hole 41, or a charging plug can pass through at least part of the through hole 41 to be connected with the charging port 20, so as to charge the power supply 13.

[0120] More specifically, with reference toFigure 3 The support 19 comprises a hollow protruding column 191, at least a part of the charging port 20 is held in the hollow cavity of the protruding column 191, the main body assembly 1 further comprises a third circuit board 1a, the charging port 20 is fixed on the third circuit board 1a and electrically connected with the third circuit board 1a. The main body assembly 1 further comprises a third electrode group 1b, the third electrode group 1b is electrically connected with the second circuit board 18 and the third circuit board 1a. The second circuit board 18 or the third circuit board 1a can be provided with a charging circuit, the charging circuit is used for charging management and charging protection of the power supply 13, and overcharging is prevented.

[0121] In some embodiments, the main body assembly 1 and the adjustment assembly 2 can be arranged in a manner as shown in Figure 3 The main body assembly 1 and the adjustment assembly 2 can be arranged in a manner as shown in The main body assembly 1 and the adjustment assembly 2 can be arranged in a manner as shown in

[0122] The main body assembly 1 and the adjustment assembly 2 can be arranged in a manner as shown in Figure 3 The main body assembly 1 and the adjustment assembly 2 can be arranged in a manner as shown in The main body assembly 1 and the adjustment assembly 2 can be arranged in a manner as shown in

[0123] The main body assembly 1 and the adjustment assembly 2 can be arranged in a manner as shown in The main body assembly 1 and the adjustment assembly 2 can be arranged in a manner as shown in

[0124] The main body assembly 1 and the adjustment assembly 2 can be arranged in a manner as shown in Figures 1-3The aerosol-generating device 100 further comprises an elastic member 5, one end of which abuts against the adjustment assembly 1, and the opposite end of which abuts against the main body assembly 2 or the end cover 4 or the support 19, so that the adjustment assembly floats in the longitudinal direction relative to the main body assembly during movement of the adjustment assembly in the lateral direction between different holding positions of the main body assembly.

[0125] Specifically, the elastic member 5 can comprise a spring, which can be arranged around the protrusion 191.

[0126] In some embodiments, when the adjustment assembly 2 is located in at least one holding position, the adjustment assembly 2 provides different air inlet areas to the airflow inlets of the first and second atomizers 11 and 12. For example, when the adjustment assembly 2 is located in one of the holding positions, the adjustment assembly 2 provides an air inlet area S1 to the airflow inlet of the first atomizer 11 and an air inlet area S2 to the airflow inlet of the second atomizer 12, S2 > S1 ≥ 0 mm 2 , or S1 > S2 ≥ 0 mm 2 . Of course, when the adjustment assembly 2 is located in at least one holding position, the adjustment assembly 2 provides the same air inlet area to the airflow inlets of the first and second atomizers 11 and 12. For example, when the adjustment assembly 2 is located in one of the holding positions, S1 = S2 ≥ 0 mm 2 .

[0127] In some embodiments, when the adjustment assembly 2 is located in at least two different holding positions, the adjustment assembly 2 provides the same air inlet area to the first atomizer 11. For example, when the adjustment assembly 2 is moved from at least one of the holding positions to another holding position, the air inlet area of the first atomizer 11 can remain unchanged.

[0128] In some embodiments, when the adjustment assembly 2 is located in at least two different holding positions, the adjustment assembly 2 provides different air inlet areas to the first atomizer 11. Therefore, the air inlet area provided by the adjustment assembly 2 to the first atomizer 11 can be changed by changing the holding position of the adjustment assembly 2.

[0129] Further, the first atomizer 11 has different air inlet areas when the adjustment assembly 2 is located in different holding positions. Therefore, the air inlet area of the first atomizer 11 can be changed once for each change of the holding position of the adjustment assembly 2.

[0130] In some embodiments, when the adjustment assembly 2 is located in at least two different holding positions, the adjustment assembly 2 provides the same air inlet area to the second atomizer 12. For example, when the adjustment assembly 2 is moved from at least one of the holding positions to another holding position, the air inlet area of the second atomizer 12 can remain unchanged.

[0131] In some embodiments, the adjustment assembly 2 provides different air intake areas for the second atomizer 12 when the adjustment assembly 2 is located in at least two different holding positions. The air intake area provided by the adjustment assembly 2 for the second atomizer 12 can thus be changed by changing the holding position of the adjustment assembly 2.

[0132] Further, the second atomizer 12 has different air intake areas when the adjustment assembly 2 is located in different holding positions. The air intake area of the second atomizer 12 can thus be changed each time the holding position of the adjustment assembly 2 is changed.

[0133] In some embodiments, the air intake area of at least one of the first atomizer 11 and the second atomizer 12 changes each time the holding position of the adjustment assembly 2 is changed.

[0134] As an example, the air intake area of the first atomizer 11 and the air intake area of the second atomizer 12 change in opposite directions when the adjustment assembly 2 is moved from at least one holding position to another holding position. For example, the air intake area of the first atomizer 11 increases and the air intake area of the second atomizer 12 decreases when the adjustment assembly 2 is moved from at least one holding position to another holding position.

[0135] As an example, the air intake area of the first atomizer 11 and the air intake area of the second atomizer 12 change in the same direction. For example, the air intake area of the first atomizer 11 and the air intake area of the second atomizer 12 both increase or both decrease when the adjustment assembly 2 is moved from at least one holding position to another holding position.

[0136] In some embodiments, the air intake area of the first atomizer 11 and the air intake area of the second atomizer 12 both remain unchanged when the adjustment assembly 2 is located in at least two different holding positions, but the electric power provided by the power supply 13 to the first atomizer 11 and / or the second atomizer 12 changes.

[0137] In some embodiments, the electric power provided by the power supply 13 to the first atomizer 11 and the second atomizer 12 both remains unchanged when the adjustment assembly 2 is located in at least two different holding positions, but the air intake area of the first atomizer 11 and / or the air intake area of the second atomizer 12 changes.

[0138] In some embodiments, reference can be made to Figure 1 , Figure 4 and Figure 5The adjustment assembly 2 includes a plurality of docking portions, at least some of the plurality of docking portions being perforated docking portions 26 that allow airflow to pass through, and at least two of the perforated docking portions 26 have different air inlet areas. The adjustment assembly 2 is configured to be selectively positioned in different holding positions to selectively position two of the docking portions to correspond to the first air hole 115 of the first atomizer 11 and the second air hole 125 of the second atomizer 12, respectively, so that the two docking portions form the airflow inlet of the first atomizer 11 and the airflow inlet of the second atomizer 12, respectively. Thus, the air inlet area of the first atomizer 11 and the air inlet area of the second atomizer 12 can be changed simultaneously by changing the holding position of the adjustment assembly 2.

[0139] The air inlet area of the first atomizer 11 can be changed by changing the docking portion corresponding to the first air hole 115. And / or, the air inlet area of the second atomizer 12 can be changed by changing the docking portion corresponding to the second air hole 125.

[0140] In some embodiments, reference can be made to Figure 4 and Figure 5 The aerosol generating device 100 includes a plurality of first air inlet gears, the perforated docking portions 26 include a plurality of first docking portions 261, and the adjustment assembly 2 is configured to be positioned in different holding positions when the aerosol generating device 100 adopts different first air inlet gears, and when the aerosol generating device 100 adopts any first air inlet gear, there are two first docking portions 261 that form the airflow inlet of the first atomizer 11 and the airflow inlet of the second atomizer 12, respectively.

[0141] The first docking portions 261 have a first air inlet area, so that when the aerosol generating device 100 adopts the first air inlet gears, the first atomizer 11 and the second atomizer 12 have the same air inlet area.

[0142] The first air inlet gears adopted by the aerosol generating device 100 can be changed by changing the holding position of the adjustment assembly 2, and when the adjustment assembly 2 is moved from one holding position to another holding position, the aerosol generating device 100 can be changed from one first air inlet gear to another first air inlet gear. However, although the first atomizer 11 and the second atomizer 12 have the same air inlet area when the aerosol generating device 100 adopts different first air inlet gears, the power supply 13 can provide different electric power to the first atomizer 11 and / or the second atomizer 12 when the aerosol generating device 100 adopts different first air inlet gears.

[0143] In some embodiments, reference can be made to Figure 1 and Figure 4, part of the plurality of docking portions is a non-hole docking portion 27 that prevents airflow from passing through, and the air inlet area of the non-hole docking portion 27 can be infinitely close to 0 mm 2 When the non-hole docking portion 27 corresponds to the first air hole 115, the adjustment assembly 2 can block the external air from flowing into the first air hole 115. Similarly, when the non-hole docking portion 27 corresponds to the second air hole 125, the adjustment assembly 2 can block the external air from flowing into the second air hole 125.

[0144] As a typical example, when the adjustment assembly 2 is located in one of the holding positions, the aerosol generating device 100 adopts the second air inlet gear, and one of the hole docking portions 26 forms the airflow inlet of the first atomizer 11, and one of the non-hole docking portions 27 forms the airflow inlet of the second atomizer 12.

[0145] Therefore, by changing the holding position of the adjustment assembly 2, when the adjustment assembly 2 is located in a specific holding position, the aerosol generating device 100 adopts the second air inlet gear, and at this time, the adjustment assembly 2 makes the air path of the external air entering the first air hole 115 conductive, while the adjustment assembly 2 blocks the external air from flowing into the second air hole 125.

[0146] Further, the hole docking portion 26 includes one or more second docking portions 262, and the second docking portion 262 has a second air inlet area. In the hole docking portion 26, the second docking portion 262 has the largest air inlet area, that is, the second air inlet area is larger than the first air inlet area.

[0147] When the aerosol generating device 100 adopts the second air inlet gear, the second docking portion 262 forms the airflow inlet of the first atomizer 11. Therefore, when the adjustment assembly 2 blocks the external air from flowing into the second air hole 125, the first atomizer 11 has the largest air inlet area.

[0148] When the aerosol generating device 100 adopts the second air inlet gear, the power supply 13 provides the largest electric power to the first atomizer 11. Therefore, the electric power provided by the power supply 13 to the first atomizer 11 when the aerosol generating device 100 adopts the second air inlet gear is greater than the maximum electric power provided by the power supply 13 to the first atomizer 11 when the aerosol generating device 100 adopts the first air inlet gear.

[0149] When the aerosol generating device 100 adopts the second air inlet gear, the power supply 13 provides the smallest electric power to the second atomizer 12, and even the electric power provided by the power supply 13 to the second atomizer 12 can be 0 W. Therefore, when the aerosol generating device 100 adopts the second air inlet gear, the aerosol generated by the aerosol generating device 100 can not include the second aerosol.

[0150] As a typical example, when the adjustment assembly 2 is located at one of the holding positions, the aerosol generating device 100 adopts the third air intake gear, and one of the hole-featured abutments 26 forms the airflow inlet of the second atomizer 12, and one of the non-hole-featured abutments 27 forms the airflow inlet of the first atomizer 11.

[0151] Thus, by changing the holding position of the adjustment assembly 2, when the adjustment assembly 2 is located at a specific holding position, the aerosol generating device 100 adopts the third air intake gear, and at this time, the adjustment assembly 2 causes the external air to flow into the air path of the second air hole 125, while the adjustment assembly 2 blocks the external air from flowing into the first air hole 115.

[0152] Further, when the aerosol generating device 100 adopts the third air intake gear, the second abutment 262 forms the airflow inlet of the second atomizer 12. Thus, when the adjustment assembly 2 blocks the external air from flowing into the first air hole 115, the second atomizer 12 has the largest air intake area.

[0153] When the aerosol generating device 100 adopts the third air intake gear, the power supply 13 provides the second atomizer 12 with the largest electric power.
