Detailed ways

The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

In one embodiment, as shown in FIG. 1, a method of controlling an aerosol generating apparatus is provided, including the following:

Step S1: Detecting a single smoking parameter of the user when the aerosol generating device is in operation; preferably, the smoking parameter includes, but is not limited to, one or more of a number of smoking mouths, a smoking duration, and an inhaled smoke amount. It will be understood that the aerosol generating device includes, but is not limited to, an atomized electronic cigarette, an electronic flue-cured tobacco, and a combination of the two.

Step S2: determining, according to the detected single smoking parameter, whether the currently accumulated smoking parameter reaches a preset threshold; understandably, when the detected smoking parameter is the number of smoking mouths, the direct judgment may be directly determined in the step. Whether the number of smoking accounts currently accumulated by the user reaches a preset threshold, and the number of smoking mouths can be set according to the type of aerosol generating device that the user smokes. For example, an electronic baking flue can set a preset threshold of 15 smoking mouths. -20 mouth; and some atomized electronic cigarettes can set the number of smoking ports to about 300, and an aerosol generating device that combines atomized electronic cigarettes with electronic flue-cured tobacco can be set to another value. Similarly, when the detected smoking parameter is the amount of inhaled smoke, the preset threshold of the amount of smoke can be set according to the demand; in some embodiments, Simultaneously monitoring and detecting the number of smoking mouths and the amount of inhaled smoke, and after one or more of the parameters reaches a preset threshold, the action in step S3 is performed to issue a prompt message.

Step S3: When the current smoking parameter of the user reaches a preset threshold, the prompt information is sent; the prompt information is used to prompt the user to replace the tobacco and/or the smoke oil. It can be understood that the prompt information can be set according to requirements. For example, the prompt information can be in the form of sound, vibration, or light, and the setting parameters of the sound include the size of the sound and the length of the sound; The frequency of vibration, the amplitude of vibration and the length of vibration, etc.; and the setting of the light includes the color of the light, the brightness of the light, the light is always on or the frequency of its flashing. Understandably, in the present application, different settings may be corresponding to different prompt information, for example, the green light is always on, indicating that the user is prompted to replace the tobacco, the red light is always on, indicating that the user is prompted to replace the smoke oil, and the red light is high. The frequency flashing indicates that there are too many cigarettes at present, prompting the user to suspend smoking.

Further, in some embodiments, if the current accumulated smoking parameter of the user does not reach the preset threshold, returning to step S1 to continue detecting the single smoking parameter of the user when the aerosol generating device operates.

The application can detect the current smoking parameters of the user, thereby promptly reminding the user to replace the tobacco or/and the smoke oil, so as to ensure that the user greatly controls the generation of harmful substances while smoking the cigarette, thereby improving the user experience.

In some embodiments, the step S1 specifically includes: detecting, by the airflow sensor, a single smoking parameter of the user when the tobacco heating element and/or the liquid aerosol atomizing element of the aerosol generating device is energized for heating, the smoking parameter It includes one or more of the number of smoking mouths, the length of smoking, and the amount of inhaled smoke. That is, in this embodiment, the airflow sensor can be directly used to detect the smoking parameter, and it can be directly determined according to the detection result whether the accumulated smoking parameter of the current user has reached a preset threshold; thereby determining whether the tobacco or the liquid smoke needs to be replaced. Specifically, when the user is pumping, the airflow sensor can detect the velocity of the smoke flow at the time of the suction and the time when the smoke passes (the duration of smoking), and the above parameters are combined with the cross-sectional area of the smoke passage (the data is determined at the time of design) It is possible to calculate the amount of smoke inhaled by the user during the suction; the user inserts the cigarette (ie, the tobacco heating element of the aerosol generating device and/or the atomizing element of the aerosol is energized for heating), and the control circuit starts to be used for each single time. Inhalation of smoke The amount is accumulated, and when the accumulated value reaches the preset threshold (set according to demand), a prompt message is sent to remind the user to replace the tobacco/smoke liquid, and/or to automatically power off (ie, proceed to step S4).

In some embodiments, as shown in FIG. 2, the step S1 specifically includes:

Step S11, detecting the output power of the aerosol generating device when the tobacco heating element and/or the soot atomizing element of the aerosol generating device is energized for heating, and determining whether the output power is raised to a preset power range That is, in this embodiment, when the tobacco heating element and/or the soot atomizing element of the aerosol generating device is energized for heating, the output power of the aerosol generating device rises to a preset power range; Therefore, when the output power of the aerosol generating device rises to a preset power range, the user starts smoking, and at this point, it is possible to proceed to step S2 to obtain the current electrical performance parameter of the aerosol generating device. In some embodiments, the electrical performance parameter comprises an output power of the aerosol generating device, an output voltage, an output current, a resistance of the tobacco heating element, a resistance of the aerosol atomizing element, a tobacco heating element, and a soot atomization One or more of the energy consumed by the component, and the like. In the present application, the temperature of the aerosol generating device is constant when not pumping, and when the user performs suction, cold air enters, at which time the temperature of the aerosol generating device drops, and during smoking, the tobacco is heated. The component and/or the aerosol liquid atomizing element is heated in the user's pumping action. At this time, the resistance is reduced, the current is increased, and the power is also increased. The above changes in the electrical performance parameters can be detected by the control circuit. In the detection process, it can also be clarified whether there is currently a user performing a pumping action, and the smoking parameter can also be obtained by the electrical performance parameter obtained by the control circuit. Step S12: Acquire the current electrical performance parameter of the aerosol generating device when the output power is raised to a preset power range; understandably, the obtaining of the electrical performance parameter may be acquired by the control circuit. Specifically, when the user pumps, as described above, the output power of the tobacco heating element and/or the aerosol atomizing element (eg, the heating element) is increased, and the combined output power and the heating time of the heating element are combined. The data (that is, the duration of smoking) can be used to calculate the electrical energy consumed by the user each time he draws, and the user inserts the cigarette (ie, the tobacco heating element of the aerosol generating device and/or the aerosolizing atomizing element is energized for heating) The control circuit starts to sum up and sum the power consumed by each single pumping, and sends a prompt message when the preset threshold is set (according to the demand), prompting the user to replace the cigarette/smoke liquid, and/or automatically power off ( That is, the process proceeds to step S4).

Step S13: The electrical performance parameter is analyzed by a preset control circuit to obtain a single smoking parameter of the user, and the smoking parameter includes one or more of a number of smoking mouths, a smoking duration, and an inhaled smoke amount. It can be understood that the smoking duration can be obtained by analyzing the electrical performance parameter by the control circuit, or can be directly obtained by a preset timer in the aerosol generating device; the number of smoking mouths can be obtained by analyzing the electrical performance parameters by the control circuit. It can also be directly obtained through the preset airflow sensor in the aerosol generating device; and the amount of inhaled smoke can also be calculated according to parameters such as the number of smoking ports and the length of smoking, or directly obtained through the preset airflow sensor in the aerosol generating device. .

In some embodiments, as shown in FIG. 3, the method further includes the following steps:

Step S4: When the smoking parameter currently accumulated by the user reaches a preset threshold, the tobacco heating element and/or the smoke liquid atomizing element of the aerosol generating device are controlled to be powered off to stop heating. In some embodiments, the smoking parameter comprises one or more of a number of smoking mouths, a length of smoking time, and an amount of inhaled smoke. It can be understood that, in this embodiment, when the detected smoking parameter is the number of smoking mouths, in this step, it can be directly determined whether the current accumulated number of smoking mouths of the user reaches a preset threshold, and the number of smoking mouths can be based on the gas consumed by the user. The type of the sol generating device is set. For example, some electronic flue-cured tobacco can set the preset threshold of the number of smoking mouths to be 15-20 mouths; and some atomized electronic cigarettes can set the number of smoking ports to be about 300 mouths. An aerosol generating device that combines atomized e-cigarettes with electronic flue-cured tobacco can be set to another value. Similarly, when the detected smoking parameter is the amount of inhaled smoke, the preset threshold of the amount of smoke can be set according to the demand; in some embodiments, the number of detected smoking ports and the amount of inhaled smoke can also be monitored simultaneously, and one of them is The tobacco heating element and/or the soot atomizing element of the aerosol generating device are controlled to be de-energized to stop heating after the plurality or parameters have reached a predetermined threshold.
