[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0044] An aerosol generator is a product that atomizes a matrix into an aerosol through heating or other means. When a user inhales, the aerosol flows with the airflow generated by the user's inhalation and exits the aerosol generator. The suction resistance of the aerosol generator is a crucial factor determining the taste of the aerosol exiting the generator.

[0045] In related technologies, aerosol generating devices are equipped with a toggle adjustment mechanism, which includes a sliding adjustment plate. By sliding the adjustment plate, the area of ​​the air inlet blocked by the plate is changed, thereby adjusting the suction resistance of the aerosol generating device. However, this toggle adjustment mechanism is manually operated, resulting in poor ease of use for the aerosol generating device.

[0046] In view of the above problems, this application provides an adaptive suction resistance adjustment mechanism and an aerosol generating device, aiming to solve the technical problem of poor ease of use of the aerosol generating device.

[0047] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0048] Please refer to Figures 1 to 4 This application provides an adaptive suction resistance adjustment mechanism for use in an aerosol generating device, used to adjust the air pressure in the atomizing air passage 5 of the aerosol generating device, including a base 1, an air regulating component 2 and a power component 3.

[0049] The base 1 has an air regulating port 11, which is connected to the atomizing air passage 5. An air regulating component 2 is slidably connected to the base 1, and is arranged adjacent to the air regulating port 11. The air regulating component 2 is used to adjust the air intake area of ​​the air regulating port 11. A power component 3 is mounted on the base 1 and connected to the air regulating component 2. The power component 3 is used to drive the air regulating component 2 to move according to the air pressure in the atomizing air passage 5, thereby adjusting the air intake area of ​​the air regulating port 11 and maintaining the air pressure in the atomizing air passage 5 within a preset pressure range.

[0050] It should be noted that the air regulating component 2 is arranged adjacent to the air regulating port 11, meaning that the air regulating component 2 is located on one side of the air regulating port 11 along its axial direction. The air regulating component 2 is slidably attached to the end face around the air regulating port 11. By sliding the air regulating component 2, the area covered by the air regulating port 11 can be changed, that is, the air intake area of ​​the air regulating port 11 can be changed.

[0051] It should be noted that when the air intake area of ​​the air regulating port 11 is suitable, when the aerosol generating device is drawn in, the airflow can smoothly enter the atomizing air channel 5 from the air regulating port 11. After flowing through the atomizing core, the airflow can carry the aerosol and smoothly exit the aerosol generating device. At this time, the suction resistance of the aerosol generating device is relatively moderate, and the air pressure in the atomizing air channel 5 is within the preset air pressure range; therefore, the power component 3 does not need to drive the air regulating component 2 to move.

[0052] It should be noted that when the air intake area of ​​the air regulating port 11 is too small, the airflow will be obstructed when the aerosol generator is being drawn in, requiring greater force to draw the airflow into the atomizing channel 5. In this case, the suction resistance of the aerosol generator is relatively high, and significant resistance must be overcome to allow the airflow to move. The air inside the atomizing channel 5 is under a relatively negative pressure, resulting in a low pressure (below the preset pressure range). Therefore, the power component 3 needs to move the air regulating component 2 to increase the air intake area of ​​the air regulating port 11 to a suitable size, making the suction resistance of the aerosol generator more moderate. This ensures that when the aerosol generator is being drawn in, the airflow can smoothly enter the atomizing channel 5 from the air regulating port 11, and the pressure inside the atomizing channel 5 remains within the preset pressure range.

[0053] It should be noted that when the air intake area of ​​the air regulating port 11 is too large, the airflow can easily enter the atomizing channel 5 through the air regulating port 11 when the aerosol generating device is being drawn in, resulting in a faster airflow velocity within the atomizing channel 5. In this case, the suction resistance of the aerosol generating device is relatively low, and the air pressure within the atomizing channel 5 is high (above the preset air pressure range). Therefore, the power component 3 needs to move the air regulating component 2 to reduce the air intake area of ​​the air regulating port 11 to a suitable size, making the suction resistance of the aerosol generating device relatively moderate. This ensures that when the aerosol generating device is being drawn in, the airflow velocity within the atomizing channel 5 remains within a suitable range, and the air pressure within the atomizing channel 5 remains within the preset air pressure range.

[0054] It is understandable that the air pressure within the atomizing airway 5 is closely related to the air intake area of ​​the air regulating port 11. When the air intake area of ​​the air regulating port 11 is small, the suction resistance of the aerosol generating device is large, and the air pressure within the atomizing airway 5 is lower than the preset air pressure range when the aerosol generating device is being drawn in. When the air intake area of ​​the air regulating port 11 is large, the suction resistance of the aerosol generating device is small, and the air pressure within the atomizing airway 5 is higher than the preset air pressure range when the aerosol generating device is being drawn in. When the air intake area of ​​the air regulating port 11 is suitable, the suction resistance of the aerosol generating device is suitable, and the air pressure within the atomizing airway 5 is within the preset air pressure range when the aerosol generating device is being drawn in. Therefore, whether the air pressure within the atomizing airway 5 is within the preset air pressure range can reflect whether the air intake area of ​​the air regulating port 11 is suitable. Therefore, in the adaptive suction resistance adjustment mechanism of this application embodiment, the power component 3 drives the air regulating component 2 to move according to the air pressure in the atomizing air passage 5 to adjust the air intake area of ​​the air regulating port 11, thereby adjusting the suction resistance of the aerosol generating device and adjusting the air pressure in the atomizing air passage 5, so that the air pressure in the atomizing air passage 5 is maintained within a preset air pressure range. Furthermore, since the power component 3 is configured to drive the air regulating component 2 to move according to the air pressure in the atomizing air passage 5 to adjust the air intake area of ​​the air regulating port 11, so that the air pressure in the atomizing air passage 5 is maintained within a preset air pressure range, the suction resistance of the aerosol generating device can be adaptively adjusted according to the air pressure in the atomizing air passage 5, eliminating the need for manual adjustment by the user and improving the ease of use of the aerosol generating device.

[0055] In the adaptive suction resistance adjustment mechanism of the first aspect embodiment of this application, the power component 3 can drive the air regulating component 2 to move relative to the air regulating port 11 between a first preset position and a second preset position; when the air regulating component 2 is located at the first preset position, the air intake area of ​​the air regulating port 11 is a first area; when the air regulating component 2 is located between the first preset position and the second preset position, the air intake area of ​​the air regulating port 11 is a second area; when the air regulating component 2 is located at the second preset position, the air intake area of ​​the air regulating port 11 is a third area.

[0056] In some implementations, the first area, the second area, and the third area increase sequentially.

[0057] Optionally, in the above embodiment, if the base 1 is only provided with an air regulating port 11, then the first area is greater than zero. When the air regulating component 2 is located in the first preset position, the airflow can flow into the atomizing air channel 5 through the air regulating port 11 when the aerosol generating device is drawn in. Please refer to... Figure 3 Optionally, in the above embodiment, the base 1 is also provided with an air inlet 12, which is connected to the atomizing air channel 5, so the first area is equal to zero or greater than zero.

[0058] In other embodiments, the first area, the second area, and the third area decrease sequentially.

[0059] Optionally, in the above embodiment, the base 1 is only provided with an air regulating port 11, so the third area is greater than zero. When the air regulating component 2 is located in the second preset position, the airflow can flow into the atomizing air channel 5 through the air regulating port 11 when the aerosol generating device is drawn in. Optionally, in the above embodiment, the base 1 is also provided with an air inlet 12, which is connected to the atomizing air channel 5, so the third area is equal to zero or greater than zero.

[0060] The adaptive suction resistance adjustment mechanism of the first aspect embodiment of this application is described below with the first area, second area and third area increasing sequentially as an example.

[0061] Please refer to Figure 2 and Figure 3 In some embodiments, the power assembly 3 includes a transmission member 31. One end of the transmission member 31 is connected to the base 1, and the end of the transmission member 31 away from the base 1 is connected to the air regulating assembly 2. The transmission member 31 is used to drive the air regulating assembly 2 to move, thereby adjusting the air intake area of ​​the air regulating port 11.

[0062] In the above embodiment, the transmission component 31 can drive the air regulating component 2 to move relative to the air regulating port 11 between a first preset position and a second preset position.

[0063] In some embodiments, the transmission member 31 is made of shape memory metal and is configured to shorten in length when the temperature of the transmission member 31 is greater than or equal to a preset temperature. Furthermore, when the temperature of the transmission member 31 is greater than or equal to the preset temperature, the length difference of the transmission member 31 is positively correlated with the temperature difference of the transmission member 31.

[0064] It is understandable that shape memory metals can deform from their initial shape (by being compressed, stretched, etc.) into a deformed shape under external force. When the temperature of the shape memory metal is greater than or equal to its recovery temperature, it will automatically return to its initial shape. When the temperature of the shape memory metal is less than its recovery temperature, it will return to its deformed shape.

[0065] It should be noted that the preset temperature in this embodiment is closely related to the shape memory metal material used in the transmission component 31. Specifically, the preset temperature is greater than or equal to the recovery temperature of the shape memory metal material used in the transmission component 31. For example, the shape memory metal material used in the transmission component 31 is a nickel-titanium alloy wire with a diameter of 0.15 mm and a length of 65 mm, and the preset temperature is 90°C-110°C.

[0066] In the above embodiment, when the air regulating component 2 is located at the first preset position, the air intake area of ​​the air regulating port 11 is the first area, and the transmission component 31 is stretched into a deformed state. At this time, the length of the transmission component 31 is at its longest. Utilizing the shape memory effect of the shape memory metal material, by increasing the temperature of the transmission component 31 to a temperature greater than or equal to a preset temperature, the shape of the transmission component 31 will change, and the length of the transmission component 31 will decrease. This allows the transmission component 31 to drive the air regulating component 2 to slide relative to the air regulating port 11 from the first preset position to the second preset position, thereby increasing the air intake area of ​​the air regulating port 11. When the temperature of the transmission component 31 drops to below the preset temperature, the shape of the transmission component 31 will change, and the length of the transmission component 31 will increase. This allows the air regulating component 2 to slide relative to the air regulating port 11 from the second preset position to the first preset position, thereby decreasing the air intake area of ​​the air regulating port 11.

[0067] It should be noted that when the air regulating component 2 is in the first preset position, the length of the transmission component 31 is the first length, and the temperature of the transmission component 31 is the first temperature. When the temperature of the transmission component 31 rises to the second temperature, and the second temperature is greater than or equal to the preset temperature, the length of the transmission component 31 is the second length. The length difference of the transmission component 31 is the difference between the first length and the second length, and the temperature difference of the transmission component 31 is the difference between the second temperature and the first temperature.

[0068] Optionally, in some embodiments, the power assembly 3 further includes a heating element for heating the transmission component 31. When the air pressure in the atomizing air passage 5 is low (below the preset air pressure range), the heating element is activated, causing the temperature of the transmission component 31 to rise to the preset temperature, thereby shortening the length of the transmission component 31. This allows the transmission component 31 to drive the air regulating assembly 2 to move, thereby increasing the air intake area of ​​the air regulating port 11 and reducing the suction resistance of the aerosol generating device.

[0069] Optionally, in some embodiments, the aerosol generating device includes a power supply 4. When the air pressure in the atomizing airway 5 is low (below the preset air pressure range), the power supply 4 directly supplies power to the transmission component 31, that is, the transmission component 31 self-heats, causing the temperature of the transmission component 31 to rise to the preset temperature, thereby shortening the length of the transmission component 31. This allows the transmission component 31 to drive the air regulating component 2 to move, thereby increasing the air intake area of ​​the air regulating port 11 and reducing the suction resistance of the aerosol generating device.

[0070] In the above embodiment, the power component 3 is configured such that when the air pressure in the atomizing air passage 5 is low (below a preset air pressure range), the power supply 4 provides a first voltage to the transmission component 31, causing the temperature of the transmission component 31 to rise to a second temperature. For example, the transmission component 31 uses a shape memory metal material of nickel-titanium alloy wire with a wire diameter of 0.15 mm and a length of 65 mm. The power supply 4 provides a voltage of 3.12 V to the transmission component 31, resulting in a current of 1060 mA within the transmission component 31. Within 0.15 s, the transmission component 31 outputs a heat power of 0.49 J, heating the transmission component 31 to 90°C-110°C.

[0071] In the above embodiment, the power component 3 is further configured such that when the air pressure in the atomizing airway 5 is maintained within a preset air pressure range for a duration greater than or equal to a preset time, the power supply 4 provides a second voltage to the transmission component 31, maintaining the temperature of the transmission component 31 at a third temperature, thus ensuring that the length of the transmission component 31 remains unchanged, thereby maintaining the constant suction resistance of the aerosol generating device. Optionally, the preset time is 0.01s-0.05s, for example, 0.02s, 0.03s, or 0.04s. For example, the transmission component 31 uses a shape memory metal material of nickel-titanium alloy wire with a wire diameter of 0.15mm and a length of 65mm. The power supply 4 provides a second voltage to the transmission component 31, resulting in a current of 312mA within the transmission component 31, thereby keeping the temperature of the transmission component 31 constant.

[0072] In the above embodiment, the power component 3 is further configured such that when the aerosol generating device is no longer being drawn in, the power supply 4 no longer provides voltage to the transmission component 31, causing the temperature of the transmission component 31 to gradually decrease and the length of the transmission component 31 to increase, thereby causing the air regulating component 2 to move, thereby reducing the air intake area of ​​the air regulating port 11 and increasing the suction resistance of the aerosol generating device.

[0073] Please refer to Figure 3 and Figure 4 In some embodiments, the transmission component 31 includes a first wire 311 and a second wire 312 connected together. The first wire 311 and the second wire 312 are arranged in a "V" shape and symmetrically. The first wire 311 and the second wire 312 are connected to the air regulating component 2. The base 1 is provided with two positioning posts 13. The end of the first wire 311 away from the second wire 312 is connected to one of the positioning posts 13 and electrically connected to the positive terminal of the power supply 4. The end of the second wire 312 away from the second wire 312 is connected to the other positioning post 13 and electrically connected to the negative terminal of the power supply 4.

[0074] In the above embodiment, the first wire and the second wire are arranged in a "V" shape and are symmetrical. When the lengths of the first wire and the second wire change, the first wire and the second wire can pull the air regulating component 2 at the same time so that the air regulating component 2 can slide stably.

[0075] The above describes an implementation where the shape-memory metal transmission component 31 serves as the power source. It is understood that in other implementations, other electromechanical motion elements may be used to provide the power source. In other implementations, the power assembly 3 also includes a drive component connected to the transmission component 31 to move the transmission component 31. Under the drive of the drive component, the transmission component 31 can move the air regulating component 2 relative to the air regulating port 11 to adjust the air intake area of ​​the air regulating port 11. It is understood that the drive component is an electromechanical motion element.

[0076] Optionally, the driving component includes one of a motor, an electromagnetic coil, or a cylinder.

[0077] In some embodiments, when the driving component includes a motor, the motor is a linear motor, and the driving end of the motor is directly connected to the transmission component 31. The driving end of the motor directly generates linear motion to drive the transmission component 31 and the air regulating component 2 to slide, thereby adjusting the air intake area of ​​the air regulating port 11.

[0078] In some embodiments, the driving component includes an electromagnetic coil wound around the transmission component 31. When the electromagnetic coil is energized, it generates a magnetic field, and the transmission component 31 moves under the action of the magnetic field to drive the air regulating component 2 to slide, thereby adjusting the air intake area of ​​the air regulating port 11.

[0079] In some embodiments, when the driving component includes a cylinder, the driving end of the cylinder makes a linear motion. The driving end of the cylinder is directly connected to the transmission component 31. The driving end of the cylinder directly generates a linear motion to drive the transmission component 31 and the air regulating component 2 to slide, thereby adjusting the air intake area of ​​the air regulating port 11.

[0080] Please refer to Figure 3 and Figure 4 In some embodiments, the base 1 is provided with a groove 14 arranged in a preset direction, and the air regulating component 2 includes a slider 21 and a blocking member 22. The slider 21 is slidably disposed in the groove 14, and the slider 21 is connected to the transmission member 31 and slides with the transmission member 31. The blocking member 22 is connected to the slider 21 and can move with the slider 21 so that the blocking member 22 slides in a preset direction, and the blocking member 22 is used to block the air regulating port 11.

[0081] In the above embodiment, the slide 14 has a first end and a second end, with the first end located on the side of the second end away from the transmission member 31. When the slider 21 is located at the first end, the air regulating component 2 is located at a first preset position, and the air intake area of ​​the air regulating port 11 is the first area. When the slider 21 is located at the second end, the air regulating component 2 is located at a second preset position, and the air intake area of ​​the air regulating port 11 is the third area. When the slider 21 is located between the first end and the second end, the air regulating component 2 is located between the first preset position and the second preset position, and the air intake area of ​​the air regulating port 11 is the second area. The first area, the second area, and the third area increase sequentially.

[0082] In some embodiments, the shielding member 22 is designed with limiting structures such as hooks and grooves. The position where the first wire 311 and the second wire 312 meet is accommodated in the limiting structure to restrict the position of the transmission member 31 and prevent the transmission member 31 from detaching from the shielding member 22.

[0083] Please refer to Figure 3 and Figure 4 In some embodiments, the base 1 is further provided with a stop 15, which corresponds to the slide groove 14. The power assembly 3 also includes an elastic element 32, one end of which is connected to the slider 21, and the end of the elastic element 32 away from the slider 21 is connected to the stop 15.

[0084] In the above embodiment, when the power component 3 drives the air regulating component 2 to slide in the direction from the first preset position to the second preset position, the air regulating component 2 squeezes the elastic member 32, and the air regulating component slides against the elastic force of the elastic member 32. When the power component 3 loses its force on the air regulating component 2, the elastic member 32 returns to its original state and drives the air regulating component 2 to slide in the direction from the second preset position to the first preset position.

[0085] By incorporating the elastic element 32 and utilizing its reset function, the number of operational steps required by the user can be reduced, thus saving the user time and effort. Furthermore, the reset function of the elastic element 32 ensures that the gas regulating component 2 always remains in the correct position, preventing misalignment due to external force or misoperation.

[0086] Please refer to Figure 2 The second aspect of this application provides an aerosol generating device, including a pressure sensor 6 and the adaptive suction resistance adjustment mechanism of the first aspect embodiment described above.

[0087] The air pressure sensor 6 is located on the base 1 and is used to measure the air pressure information in the atomizing air channel 5.

[0088] By applying the adaptive suction resistance adjustment mechanism of the first aspect embodiment to the aerosol generating device, the aerosol generating device can adaptively adjust the suction resistance according to the air pressure in the atomizing airway 5, without requiring manual adjustment by the user, thereby improving the ease of use of the aerosol generating device.

[0089] It should be noted that when the air intake area of ​​the air regulating port 11 is too small, the suction resistance of the aerosol generating device is relatively large. When the aerosol generating device is being drawn in, greater force is required to draw the airflow into the atomizing channel 5. At this time, a large resistance must be overcome to make the airflow move, and the air inside the atomizing channel 5 is in a state of relative negative pressure, making the air pressure inside the atomizing channel 5 lower than the air pressure outside the aerosol generating device. The pressure sensor 6 has a response threshold that is lower than a preset air pressure range. For ease of description, the response threshold that is lower than the preset air pressure range is defined as the low response threshold. The power component 3 is configured to drive the air regulating component 2 to move when the air pressure information measured by the pressure sensor 6 in the atomizing channel 5 is lower than the low response threshold, thereby increasing the air intake area of ​​the air regulating port 11.

[0090] In some embodiments, the pressure sensor 6 has multiple different low response thresholds; the power component 3 is configured to drive the air regulating component 2 to move different distances when the pressure information in the atomizing air passage 5 measured by the pressure sensor 6 is less than different low response thresholds, so as to adjust the air intake area of ​​the air regulating port 11, and the distance that the power component 3 drives the air regulating component 2 to move is negatively correlated with the low response threshold, that is, the smaller the low response threshold, the greater the distance that the air regulating component 2 moves.

[0091] In some embodiments, the pressure sensor 6 has two low-response thresholds, a first low-response threshold and a second low-response threshold, wherein the first low-response threshold is greater than the second low-response threshold. The power component 3 is configured to not operate when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is greater than the first low-response threshold. The power component 3 is also configured to drive the adjustment component to move a first distance when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is less than the first low-response threshold but greater than the second low-response threshold. The power component 3 is further configured to drive the adjustment component to move a second distance when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is less than the second low-response threshold. The first distance is less than the second distance.

[0092] In some embodiments, the pressure sensor 6 has three low-response thresholds: a first low-response threshold, a second low-response threshold, and a third low-response threshold, wherein the first low-response threshold is greater than the second low-response threshold, and the second low-response threshold is greater than the third low-response threshold. The power component 3 is configured to not operate when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is greater than the first low-response threshold. The power component 3 is also configured to drive the adjustment component to move a first distance when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is less than the first low-response threshold but greater than the second low-response threshold. The power component 3 is further configured to drive the adjustment component to move a second distance when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is less than the second low-response threshold but greater than the third low-response threshold. The first distance is less than the second distance, and the second distance is less than the third distance.

[0093] It should be noted that when the air intake area of ​​the air regulating port 11 is too large, the suction resistance of the aerosol generating device is relatively small. When the aerosol generating device is being drawn in, the airflow velocity in the atomizing channel 5 is relatively fast, and the air pressure in the atomizing channel 5 is relatively high, making the air pressure in the atomizing channel 5 greater than the air pressure outside the aerosol generating device. The air pressure sensor 6 has a response threshold that is greater than a preset air pressure range. For ease of description, the response threshold that is greater than the preset air pressure range is defined as the high response threshold. The power component 3 is configured to drive the air regulating component 2 to move when the air pressure information in the atomizing channel 5 measured by the air pressure sensor 6 is greater than the high response threshold, thereby reducing the air intake area of ​​the air regulating port 11.

[0094] In some embodiments, the pressure sensor 6 has multiple different high response thresholds; the power component 3 is configured to drive the air regulating component 2 to move different distances when the pressure information in the atomizing airway 5 measured by the pressure sensor 6 is greater than different high response thresholds, so as to adjust the air intake area of ​​the air regulating port 11, and the distance that the power component 3 drives the air regulating component 2 to move is positively correlated with the high response threshold, that is, the larger the high response threshold, the greater the distance that the air regulating component 2 moves.

[0095] In some embodiments, the pressure sensor 6 has two high-response thresholds, a first high-response threshold and a second high-response threshold, wherein the first high-response threshold is smaller than the second high-response threshold. The power component 3 is configured to not operate when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is less than the first high-response threshold. The power component 3 is also configured to drive the adjustment component to move a fourth distance when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is greater than or equal to the first high-response threshold and less than the second high-response threshold. The power component 3 is further configured to drive the adjustment component to move a fifth distance when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is greater than or equal to the second high-response threshold. The fourth distance is less than the fifth distance.

[0096] In some embodiments, the pressure sensor 6 has three high-response thresholds: a first high-response threshold, a second high-response threshold, and a third high-response threshold, wherein the first high-response threshold is less than the second high-response threshold, and the second high-response threshold is less than the third high-response threshold. The power component 3 is configured to not operate when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is less than the first high-response threshold. The power component 3 is also configured to drive the adjustment component to move a fourth distance when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is greater than or equal to the first high-response threshold and less than the second high-response threshold. The power component 3 is further configured to drive the adjustment component to move a fifth distance when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is greater than or equal to the second high-response threshold and less than the third high-response threshold. The power component 3 is also configured to drive the adjustment component to move a sixth distance when the pressure information measured by the pressure sensor 6 within the atomizing airway 5 is greater than or equal to the third high-response threshold. The fourth distance is less than the fifth distance, and the fifth distance is less than the sixth distance.

[0097] In some embodiments, the aerosol generating device further includes a control mechanism electrically connected to the pressure sensor 6 and the power assembly 3. The control mechanism receives pressure information measured by the pressure sensor 6 and controls the power assembly 3 to adjust the air intake area of ​​the air inlet 11 based on the pressure information.
