Specifically, in one embodiment, the controller 5 is configured to control the exhaust device 2 to be turned on when a puff signal is initially received. That is, in this embodiment, when the atomizing core 12 starts to work to atomize the aerosol-generating substrate, the controller 5 controls the air discharging device 2 to be turned on, and at this time, the air discharging device 2 can assist the main body 1 to intake air and drive the aerosol to be discharged out of the main body 1 for the user to suck, so that the user can suck the aerosol more easily. Further, in this embodiment, the controller 5 is configured to control the exhaust means 2 to be turned off with a delay when the smoking signal stops being received; that is, after the user stops smoking, a part of aerosol may remain in the airflow channel 13, at this time, although the atomizing core 12 stops working, a small amount of aerosol may be generated due to the preheating of the atomizing core 12, and the aerosol may remain in the airflow channel 13 to affect the normal operation of the main body 1, at this time, after the controller 5 no longer receives the smoking signal, the exhaust device 2 is controlled to continue working and be closed with a delay, and the remaining aerosol may be discharged out of the main body 1, and the duration of the delay may be 3s to 6s, preferably 3s, so as to discharge the remaining aerosol out of the main body 1 before the user smokes again.
In another embodiment, the controller 5 may be further configured to control the exhaust apparatus 2 to be turned on when the smoking signal stops being received. In this embodiment, when a user starts smoking, the exhaust device 2 is in a closed state, and after the user stops smoking, the airflow sensor 4 senses that the pressure or flow rate of the airflow in the airflow channel 13 returns to normal, that is, the airflow stops flowing, and no smoking signal is generated any more, and the controller 5 controls the exhaust device 2 to start to work after no smoking signal is received any more, so that the aerosol remaining in the airflow channel 13 can be discharged out of the main body 1; the controller 5 may control the operation of the exhaust device 2 for 3s, 4s, 5s, etc. to ensure that all of the aerosol remaining in the airflow channel 13 is exhausted from the main body 1.
Referring to fig. 12, an embodiment of the present invention further provides an aerosol delivery control method, which includes:
s1, detecting and receiving a smoking signal generated by an airflow sensor 4 for sensing a change in air pressure or flow rate in the airflow channel 13 when the user inhales;
s2, controlling an exhaust device 2 to act according to the smoking signal to drive the airflow in the airflow channel 13, so that at least a part of the aerosol retained in the airflow channel 13 is discharged out of the airflow channel 13.
In the above steps S1 and S2, the airflow sensor 4 is disposed in the airflow path 13 of the main body 1, and can sense the change of the air pressure or the flow rate, so as to detect whether the user starts to smoke; after sensing that the user starts smoking, the exhaust device 2 can start working to drive airflow in the airflow channel 13 to flow, so that aerosol in the airflow channel 13 is taken out, the aerosol is prevented from being remained in the airflow channel 13 to generate condensate, the taste of the aerosol is guaranteed, and the user experience is improved. For example, when a user starts smoking, the pressure or flow rate of the gas in the airflow channel 13 will inevitably change, and when the airflow sensor 4 senses the changes, it can be determined that the user is smoking and generate a smoking signal, and then the smoking signal is transmitted to the controller 5, and after the controller 5 receives the smoking signal, the exhaust device 2 can be controlled to perform actions, so as to discharge the aerosol in the airflow channel 13, and prevent the aerosol from being retained in the airflow channel 13 to form condensate.
In one embodiment, the exhaust means 2 may be controlled to be operated for a first duration of time on detection of the smoking signal; the first duration may be 5s, 6s, 7s, etc., preferably the first duration is longer than the duration of the puff signal, which is the time taken by the user to draw the aerosol, typically 2-4s, and the time taken by each user is different, i.e. the air outlet means 2 continues to remain in operation after the user stops puffing to ensure that the aerosol remaining in the air flow channel 13 is expelled out of the air flow channel 13. Further, in this embodiment, the exhaust means 2 may also be controlled to delay the closing for the second duration when the disappearance of the smoking signal is detected; the second duration may be 3s to 6s, preferably 3 s; that is, when a smoking signal is detected, the exhaust device 2 is turned on to start operation, when the smoking signal is no longer detected, the exhaust device 2 continues to maintain the operating state, and is turned off to stop operation after a second duration, and during the operating period of the second duration, the exhaust device 2 can drive the airflow in the airflow channel 13 to flow out of the airflow channel 13 to carry away the aerosol remaining in the airflow channel 13.
In another embodiment, the exhaust means 2 is controlled to be operated for a third duration of time when it is detected that the smoking signal is absent. In this embodiment, when a smoking signal is detected, the exhaust device 2 remains closed, and when the smoking signal is no longer detected, the exhaust device 2 is turned on to start operation and remains in operation for a third duration, which is 3s to 6s, preferably 3s, when the user has stopped smoking, the operation of the exhaust device 2 may drive the airflow in the airflow channel 13 to continue to flow to bring out the aerosol remaining in the airflow channel 13.
In an embodiment, the step of controlling the exhaust means 2 to perform an action is interrupted and the control method is reset when a smoking signal generated by the airflow sensor 4 is detected the next time the user inhales. Since a user usually sucks a plurality of cigarettes and aerosol remains in the airflow channel 13 during each smoking, the aerosol remaining in the airflow channel 13 needs to be discharged after each smoking, and the control method needs to be reset at this time, so that the exhaust device 2 can discharge the aerosol remaining in the airflow channel 13 out of the airflow channel 13 after each smoking.
