Referring to FIG. 2 to FIG. 4 together, the mounting assembly 3 is arranged at the distal end of the liquid storage portion 11, and the first atomization cavity 111 and the second atomization cavity 112 are defined between the mounting assembly 3 and the liquid storage portion 11. The mounting assembly 3 is arranged corresponding to a first movable member 21, and the mounting assembly 3 is located at an end of the first movable member 21. A first air inlet channel 31 and a second air inlet channel 32 are provided on the mounting assembly 3, where the first air inlet channel 31 and the second air inlet channel 32 are separated from each other. The first air inlet channel 31 includes a first air inlet hole 311 and a first air outlet hole 312, where the first air inlet hole 311 is located at an end of the mounting assembly 3 facing away from the first movable member 21, and the first air inlet hole 311 is located on a side of the mounting assembly 3 close to the second atomization cavity 112; and the first air outlet hole 312 is located at an end of the mounting assembly 3 facing the first movable member 21, and the first air outlet hole 312 is in communication with the first atomization cavity 111. The second air inlet channel 32 includes a second air inlet hole 321 and a second air outlet hole 322, where the second air inlet hole 321 is located at the end of the mounting assembly 3 facing away from the first movable member 21, and the second air outlet hole 321 is located on a side of the mounting assembly 3 close to the first atomization cavity 111; and the second air outlet hole 322 is located at the end of the mounting assembly 3 facing the first movable member 21, the second air outlet hole 322 and the first air inlet hole 312 are respectively located on two sides of the mounting assembly 3, and the second air outlet hole 322 is in communication with the second atomization cavity 112.

For the foregoing mounting assembly 3, the mounting assembly 3 includes a first mounting member 33 and a second mounting member 34, where the first mounting member 33 is closer to the first atomization cavity 111 and the second atomization cavity 112 than the second mounting member 34, and the first air outlet hole 312 and the second air outlet hole 322 are provided on the first mounting member 33. The first air inlet hole 311, the second air inlet hole 321, the first air inlet channel 31, and the second air inlet channel 32 are all provided on the second mounting member 34. The first air inlet channel 31 and the second air inlet channel 32 are both cavities basically extending along the transverse direction. The first air inlet hole 311 is located on a right side of the transverse direction, and the second air inlet hole 321 is located on a left side of the transverse direction. Therefore, entering the first air inlet channel 31 from the first air inlet hole 311 may enter the first atomization cavity 111 located on the left side of the transverse direction, and entering the second air inlet channel 32 from the second air inlet hole 321 may enter the second atomization cavity 112 located on the right side of the transverse direction, thereby achieving cross arrangement of air paths.

Referring to FIG. 3 and FIG. 5, for the foregoing switching assembly 2, the switching assembly 2 includes the first movable member 21, a second movable member 22, and a toggle member 23. The first movable member 21 is arranged at an end of the mounting assembly 3, and the first movable member 21 is configured to control connection and disconnection between the first atomization cavity 111 as well as the second atomization cavity 112 and the main airway 113.

The first movable member 21 is arranged corresponding to the first atomization cavity 111 and the second atomization cavity 112, and the first movable member 21 is movably arranged. During movement of the first movable member 21, the main airway 113 is enabled to be selectively in communication with any one of the first atomization cavity 111 or the second atomization cavity 112. For example, during the movement of the first movable member 21, when the first movable member 21 causes the main airway 113 to be in communication with the first atomization cavity 111, the aerosol generated by atomization in the first atomization cavity 111 may diffuse outward through the main airway 113. During this process, an air path between the second atomization cavity 112 and the main airway 113 is blocked, so that the user cannot inhale air in the second atomization cavity 112, and a problem of liquid substrate leakage in the second atomization cavity 112 is prevented. Similarly, during the movement of the first movable member 21, when the first movable member 21 causes the main airway 113 to be in communication with the second atomization cavity 112, the aerosol generated by atomization in the second atomization cavity 112 may diffuse outward through the main airway 113. During this process, an air path between the first atomization cavity 111 and the main airway 113 is blocked, so that the user cannot inhale air in the first atomization cavity 111, and a problem of liquid substrate leakage in the first atomization cavity 111 is also prevented. In other words, when the user switches an aerosol taste of the aerosol-generating devices 100, the air path is also switched.

When flavors of the aerosols generated by atomization in the first atomization cavity 111 and the second atomization cavity 112 are different, by controlling the first movable member 21, the aerosol-generating device 100 may be switched between the two flavors.

Since the first movable member 21 is movably arranged, the first movable member 21 reciprocates among a first position, a second position, and a third position. When the first movable member 21 is located at the first position, the first atomization cavity 111 is in communication with the first aerosol outlet 1111, and the first movable member 21 blocks the second aerosol outlet 1121, so that the aerosol generated in the first atomization cavity 111 may enter the main airway 113 through the first aerosol outlet 1111. When the first movable member 21 is located at the second position, the second atomization cavity 112 is in communication with the second aerosol outlet 1121, and the first movable member 21 blocks the first aerosol outlet 1111, so that the aerosol generated in the second atomization cavity 112 may enter the main airway 113 through the second aerosol outlet 1121. When the first movable member 21 is located at the third position, the first movable member 21 opens both the first aerosol outlet 1111 and the second aerosol outlet 1121. In this case, both the first atomization cavity 111 and the second atomization cavity 112 are in communication with the main airway 113, so that the aerosol generated in the first atomization cavity 111 may enter the main airway 113, and the aerosol generated in the second atomization cavity 112 may also enter the main airway 113.

It should be noted that, when the first movable member 21 is located at the third position, the user may inhale the aerosols in the first atomization cavity 111 and the second atomization cavity 112 at the same time, and a problem of air suction is prevented.

Referring to FIG. 4 to FIG. 6, the second movable member 22 is located at the end of the mounting assembly 3 facing away from the first movable member 21, and the second movable member 22 is configured to selectively block any one of the first air inlet hole 311 or the second air inlet hole 321, or open both the first air inlet hole 311 and the second air inlet hole 321. Therefore, by controlling a position of the second movable member 22, air may be transported to any one of the first air inlet channel 31 or the second air inlet channel 32, or air may be transported to both the first air inlet hole 311 and the second air inlet hole 321, to provide air required for atomization of the liquid substrate.

The second movable member 22 is connected to the first movable member 21, to cause the second movable member 22 to move synchronously with the first movable member 21. That is, when any one of the second movable member 22 or the first movable member 21 moves, the other one of the second movable member 22 and the first movable member 21 also moves. When the first movable member 21 switches from the second position or the third position to the first position, the first movable member 21 drives the second movable member 22 to move along the transverse direction toward the first atomization cavity 111. In this case, the second movable member 22 blocks the second air inlet hole 321, and the first air inlet hole 311 is not blocked, so that external air may enter the first air inlet channel 31 through the first air inlet hole 311, and then enter the first atomization cavity 111. When the first movable member 21 switches from the first position or the third position to the second position, the first movable member 21 drives the second movable member 22 to move along the transverse direction toward the second atomization cavity 112. In this case, the second movable member 22 blocks the first air inlet hole 311, and the second air inlet hole 321 is not blocked, so that the external air may enter the second air inlet channel 32 through the second air inlet hole 321, and then enter the second atomization cavity 112. When the first movable member 21 switches from the first position or the second position to the third position, the first movable member 21 drives the second movable member 22 to move along the transverse direction toward a center of the first atomization cavity 111 and the second atomization cavity 112. In this case, the second movable member 22 does not block the first air inlet hole 311, and the second movable member 22 also does not block the second air inlet hole 321, so that the external sir may enter the first atomization cavity 111 and the second atomization cavity 112 at the same time. The synchronous movement of the second movable member 22 and the first movable member 21 may make an operation of the aerosol-generating device 100 simpler.

It may be understood that, in some embodiments, movements of the first movable member 21 and the second movable member 22 are independent of each other. That is, a movable member 21 and the second movable member 22 are respectively toggled through different buttons.

Referring to FIG. 1 and FIG. 5, the toggle member 23 is arranged across the housing 1. Specifically, a mounting slot 12 is provided on the housing 1, where the mounting slot 12 is a through slot, and the toggle member 23 may be slidably accommodated in the mounting slot 12. A side of the toggle member 23 is connected to the second movable member 22. Since the toggle member 23 is slidably arranged, when the toggle member 23 slides, the second movable member 22 is driven to move, and the first movable member 21 is further driven to move, so as to control the first movable member 21 to reciprocate among the first position, the second position, and the third position.

It may be understood that, in some embodiments, the toggle member 23 is connected to the first movable member 21. When the toggle member 23 slides, the first movable member 21 is driven to move, and the second movable member 22 is driven to move by the first movable member 21.

Referring to FIG. 7, for the foregoing first movable member 21, the first movable member 21 includes a movable portion 211, a first sealing portion 212, and a second sealing portion 213. The movable portion 211 is substantially plate-shaped. One end of the movable portion 211 is accommodated in the first atomization cavity 111, and the other end of the movable portion 211 is accommodated in the second atomization cavity 112. The movable portion 211 is movably arranged. When the movable portion 211 moves toward the first atomization cavity 111, most of the movable portion 211 is accommodated in the first atomization cavity 111, and the remaining small part of the movable portion 211 is accommodated in the second atomization cavity 112. When the movable portion 211 moves toward the second atomization cavity 112, most of the movable portion 211 is accommodated in the second atomization cavity 112, and the remaining small part of the movable portion 211 is accommodated in the first atomization cavity 111.

In this case, the first sealing portion 212 fits the first aerosol outlet 1111 to block the first aerosol outlet 1111, and in this case, the second sealing portion 213 is spaced from the second aerosol outlet 1121, so that the second aerosol outlet 1121 is not blocked, and the aerosol in the second atomization cavity 112 may enter the main airway 113 from the second aerosol outlet 1121. When the first movable member 21 is switched from the second position or the third position to the first position, the movable portion 211 moves along the transverse direction toward the first atomization cavity 111, and the movable portion 211 drives the first sealing portion 212 and the second sealing portion 213 to move along the transverse direction. In this case, the second sealing portion 213 fits the second aerosol outlet 1121 to block the second aerosol outlet 1121, and in this case, the first sealing portion 212 is spaced from the first aerosol outlet 1111, so that the first aerosol outlet 1111 is not blocked, and the aerosol in the first atomization cavity 111 may enter the main airway 113 from the first aerosol outlet 1111. When the first movable member 21 is switched from the first position or the second position to the third position, the movable portion 211 moves along the transverse direction toward the center of the first atomization cavity 111 and the second atomization cavity 112. That is, the movable portion 211 is at a centered position compared with the first atomization cavity 111 and the second atomization cavity 112. In this case, the first sealing portion 212 is spaced from the first aerosol outlet 1111, and the second sealing portion 213 is spaced from the second aerosol outlet 1121, so that the aerosol in the first atomization cavity 111 may enter the main airway 113 from the first aerosol outlet 1111, and the aerosol in the second atomization cavity 112 may enter the main airway 113 from the second aerosol outlet 1112.

Referring to FIG. 7, for the foregoing second movable member 22, the second movable member 22 includes a main body portion 221, a first connection portion 222, and a second connection portion 223.

The protruding portion 612 is accommodated in the slot 2231 of the second connection portion 223, to achieve connection between the electronic toggle switch 61 and the second movable member 22. The protruding portion 612 may further be bonded or screwed to the second connection portion 223, to increase a connection strength between the electronic toggle switch 61 and a second movable member 22.

Since the electronic toggle switch 61 is connected to the toggle member 23, the first movable member 21, or the second movable member 22, when the toggle member 23, the first movable member 21, or the second movable member 22 moves, the electronic toggle switch 61 is driven to move, to cause the control circuit board 6 to be conducted with the first heating element 4 or the second heating element 5. For example, when the toggle switch is pushed and the first movable member 21 is located at the first position, the electronic toggle switch 61 conducts electrical connection between the first heating element 4 and the control circuit board 6. In this case, the first heating element 4 is energized to generate heat. When the toggle switch is pushed and the first movable member 21 is located at the second position, the electronic toggle switch 61 conducts electrical connection between the second heating element 5 and the control circuit board 6. In this case, the second heating element 5 is energized to generate heat. When the toggle switch is pushed and the first movable member 21 is located at the third position, the electronic toggle switch 61 conducts electrical connection between the first heating element 4 and the control circuit board 6, and conducts electrical connection between the second heating element 5 and the control circuit board 6. In this case, both the first heating element 4 and the second heating element 5 are energized to generate heat.

When the first movable member 21 causes the main airway 113 to be in communication with the first atomization cavity 111, an aerosol generated by atomization in the first atomization cavity 111 may diffuse outward through the main airway 113, and an air path between the second atomization cavity 112 and the main airway 113 is blocked, so that a user cannot inhale air in the second atomization cavity 112, and a problem of liquid substrate leakage in the second atomization cavity 112 is prevented. Similarly, when the first movable member 21 causes the main airway 113 to be in communication with the second atomization cavity 112, an aerosol generated by atomization in the second atomization cavity 112 may diffuse outward through the main airway 113, and an air path between the first atomization cavity 111 and the main airway 113 is blocked, so that the user cannot inhale air in the first atomization cavity 111, and a problem of liquid substrate leakage in the first atomization cavity 111 is also prevented.
