[0025] Embodiment 1

[0026] Reference Figure 1 , which shows a working flow diagram of an aerosol-generating device provided by an embodiment of the application to prevent children from inhaling. The method comprises:

[0027] S1: Obtain the real-time air flow of the airway.

[0028] As an example, the obtaining of the real-time air flow of the airway comprises integrating an air flow meter in the airway of the aerosol-generating device to replace the traditional microphone, so as to simplify the structure of the aerosol-generating device and facilitate the improvement of the already produced aerosol-generating device.

[0029] Optionally, the air flow meter can also be integrated in the middle position of the airway of the aerosol-generating device, so as to effectively avoid the problem of false start of the aerosol-generating device caused by the influence of external environmental airflow.

[0030] Specifically, the air flow meter is used to detect the air flow of the user's puffing, in the embodiment, the air flow meter can be a thermal air flow meter or a mechanical air flow meter, the mechanical air flow meter includes a vane type air flow meter and a Karman vortex type air flow meter; the thermal air flow meter includes a MEMS gas sensor. The MEMS gas sensor includes a heating resistor and a temperature detection resistor. When the gas flows, a part of heat is taken away, so that the temperature detection resistor changes, and the temperature detection resistor sends the resistance change to the detection circuit, and the circuit processes and outputs the air flow value. The MEMS gas flow sensor has the characteristics of small size and high precision, and can detect the small change of the gas flow in the gas channel of the aerosol generating device. Those skilled in the art should understand that other types of air flow meters capable of achieving the above functions are also applicable to the present application.

[0031] Optionally, the air flow meter is an instrument for converting the inhaled air flow into an electrical signal, wherein the air flow is the volume or mass of the gas flowing through the gas channel per unit time. A signal converter connected to the air flow meter can be arranged in the gas channel to receive the electrical signal output by the air flow meter by detecting the gas flow in the gas channel, and the signal converter converts it into a corresponding digital signal that can be read to generate real-time air flow and facilitate subsequent workflow.

[0032] S2: determining whether the real-time air flow is greater than a first air flow threshold.

[0033] As an example, the first air flow threshold can be obtained by batch testing the aerosol generating device in the laboratory, so that the maximum air flow M of the forced vital capacity of adults and children using the aerosol generating device is obtained, and the maximum air flow M is the first air flow threshold. The first air flow threshold can be set to 20 ml / s.

[0034] Optionally, the first air flow threshold can be set by a related technician when producing the aerosol generating device, so that the user can select it independently in the subsequent use process. Specifically, the user can select the threshold based on the individual forced vital capacity index on the client connected to the aerosol generating device, or the user can select the threshold on the display screen of the aerosol generating device. Optionally, after the user client and the aerosol generating device are successfully matched, a communication connection is established, the user client can send multiple instruction information, and the user can select to send a specific instruction information according to the demand. The aerosol generating device and the user client are in communication connection, and the communication connection can be through Bluetooth or other wireless connection, or data line or other wired connection.

[0035] Optionally, the first air flow threshold value can be set by a skilled person in the production of the aerosol generating device to provide a first air flow threshold value range for the user to select independently in the subsequent use process, and the first air flow threshold value range can be measured according to experimental data. Specifically, the user can adjust the threshold value based on the individual lung capacity index on the client connected to the aerosol generating device, and the user can also adjust the threshold value on the display screen of the aerosol generating device.

[0036] In this way, the user can adjust the first air flow threshold value based on the individual lung capacity index, which can greatly meet the needs of different user groups. For example, the female user group has a lower lung capacity index, and they can choose a smaller first air flow threshold value. The male group has a higher lung capacity index, and they can choose a larger first air flow threshold value. It should be noted that the lower limit of the air flow threshold value range is greater than the maximum air flow of the lung capacity of children.

[0037] It should be noted that the specific way of selecting the first air flow threshold value is not limited here, and different selection methods can be used by the user based on different aerosol generating devices.

[0038] S3: In response to the real-time air flow being greater than the first air flow threshold value, the aerosol generating device is unlocked.

[0039] As an example, the step S3 includes: S31, when the real-time air flow is greater than the first air flow threshold value within a first predetermined time, the aerosol generating device is unlocked; or

[0040] S32, when N times of real-time air flow greater than the first air flow threshold value are continuously detected within a second predetermined time, the aerosol generating device is unlocked.

[0041] Optionally, the first predetermined time can be 5s-1min, and preferably the first predetermined time can be set to 10s. That is, when the real-time air flow of the user obtained within 10s is greater than the first air flow threshold value 20ml / s, the aerosol generating device can be unlocked. Otherwise, if the real-time air flow of the user obtained within 10s is less than or equal to the first air flow threshold value, the aerosol generating device will not be unlocked. More specifically, the time when the obtained real-time air flow is less than or equal to the first air flow threshold value is taken as the initial time, and then the real-time air flow obtained within 10s is counted again to see if it is greater than the first air flow threshold value. If it is greater than the first air flow threshold value, the aerosol generating device is unlocked.

[0042] Optionally, the second preset time can be 5s-1min, and preferably the second preset time can be set to 15s. That is, when the real-time air flow rate of the user obtained continuously N times within 15s is greater than the first air flow rate threshold 20ml / s, the aerosol generating device can be unlocked, otherwise, if the real-time air flow rate of the user is not obtained continuously N times within 15s, the aerosol generating device will not be unlocked.

[0043] It should be noted that the first preset time and the second preset time can be set by the relevant technical personnel according to actual needs, and are not limited here.

[0044] S4, determining whether the real-time air flow rate is greater than or equal to a second air flow rate threshold.

[0045] As an example, the second air flow rate threshold can be generated by batch testing the aerosol generating device in the laboratory to generate experimental data, or by collecting user smoking habit data to generate, so as to obtain the normal puffing air flow rate C of an adult, which is the second air flow rate threshold. The second air flow rate threshold can be set to 10ml / s. Optionally, the second air flow rate threshold can be set by the relevant technical personnel when producing the aerosol generating device to provide multiple second air flow rate thresholds for the user to select in the subsequent use process. Specifically, the user can select the threshold based on the individual's lung capacity index on the client connected to the aerosol generating device, or the user can select the threshold on the display screen of the aerosol generating device. More specifically, after the user client and the aerosol generating device are successfully matched, a communication connection is established, and the user client can send multiple instruction information, and the user can select to send a specific instruction information according to the demand. The aerosol generating device and the user client are in communication connection, and the communication connection can be through Bluetooth or other wireless connection, or data line or other wired connection.

[0046] Optionally, the second air flow rate threshold can be set by the relevant technical personnel when producing the aerosol generating device to provide a second air flow rate threshold range for the user to select in the subsequent use process, and the second air flow rate threshold range can be measured according to the experimental data. Specifically, the user can adjust the threshold based on the individual's lung capacity index on the client connected to the aerosol generating device, or the user can adjust the threshold on the display screen of the aerosol generating device.

[0047] In this way, the user can adjust the second air flow threshold value based on the individual lung capacity index, which can greatly meet the needs of different user groups. For example, the female user group has a lower lung capacity index, and they can choose a smaller second air flow threshold value. The male group has a higher lung capacity index, and they can choose a larger second air flow threshold value. It should be noted that the second air flow threshold value is usually smaller than the first air flow threshold value and larger than the maximum air flow of the child's lung capacity.

[0048] It should be noted that the specific selection of the second air flow threshold value is not limited here, and different selection methods can be used by the user based on different aerosol generating devices.

[0049] S5: In response to the real-time air flow being greater than or equal to the second air flow threshold value, causing the aerosol generating device to atomize.

[0050] As an example, when the aerosol generating device is in the unlocked state, when the user performs a suction action on the aerosol generating device again, the real-time air flow is obtained. When the real-time air flow is greater than or equal to the second air flow threshold value of 10 ml / s, the aerosol generating device in the unlocked state enters the atomization mode, i.e., the aerosol generating device works normally. When the real-time air flow is less than the second air flow threshold value of 10 ml / s, go to step S8, stop the atomization operation of the aerosol generating device, and re-lock the aerosol generating device.

[0051] As an example, when the aerosol generating device is in the unlocked state, when the user performs a suction action on the aerosol generating device again, the real-time air flow is obtained. When the real-time air flow is greater than or equal to the second air flow threshold value of 10 ml / s, the aerosol generating device in the unlocked state enters the atomization mode, i.e., the aerosol generating device works normally. When the real-time air flow is less than the second air flow threshold value of 10 ml / s, stop the atomization operation of the aerosol generating device, and re-lock the aerosol generating device; or when the real-time air flow is less than the second air flow threshold value of 10 ml / s, continue to obtain the real-time air flow. When the real-time air flow is less than the second air flow threshold value for n times in the third preset time, stop the atomization operation of the aerosol generating device, and re-lock the aerosol generating device, which solves the problem of immediately stopping the atomization operation and affecting the user experience.

[0052] As an example, the child-proof aerosol generating device working method further includes step S0: initializing the aerosol generating device.

[0053] Optionally, the processor of the aerosol generating device performs multiple data storage and judgment. When the current puff data processing is completed, the control signal changed by the last puff data processing needs to be reset to avoid affecting the data processing of the next puff. In an embodiment, the airflow meter generates multiple puff data stored in the memory within a short period of time. If not processed in time, there will be a lot of temporary data occupying a large amount of storage space, causing waste of storage space. Therefore, the aerosol generating device needs to be initialized in time to improve the data processing efficiency and accuracy.

[0054] As an example, when the aerosol generating device cannot be unlocked, the aerosol generating device cannot be normally atomized, and / or the real-time airflow rate exceeds the preset adjustable range of the first airflow rate threshold and / or the second airflow rate threshold, a prompt information is sent. The prompt information includes but is not limited to one or a combination of the following alert methods: sound, vibration, light, text, etc. By sending prompt information to the user, the user's experience is effectively improved.

[0055] Embodiment 2

[0056] As shown in Figure 2 , it shows a working flow diagram of an aerosol generating device for preventing child misuse according to another embodiment of the present application. The method comprises:

[0057] S1: obtaining a real-time airflow rate of an airway.

[0058] S2: determining whether the real-time airflow rate is greater than a first airflow rate threshold.

[0059] S3: in response to the real-time airflow rate being greater than the first airflow rate threshold, unlocking the aerosol generating device.

[0060] S4: determining whether the real-time airflow rate is greater than or equal to a second airflow rate threshold.

[0061] S5: in response to the real-time airflow rate being greater than or equal to the second airflow rate threshold, causing the aerosol generating device to atomize.

[0062] S6: determining whether the real-time airflow rate meets a preset condition within a third preset time.

[0063] S7: in response to the real-time airflow rate meeting the preset condition within the third preset time, causing the aerosol generating device to be automatically locked and enter a child lock mode.

[0064] As an example, steps S1-S5 have been described in detail in Embodiment 1 above, and will not be repeated here.

[0065] As an example, step S7 includes: S71, if no suction action is detected from the user within a third preset time period, the aerosol generating device is automatically locked, putting it into child lock mode; or

[0066] S72. When the real-time airflow rate is less than the second airflow rate threshold within the third preset time, the aerosol generating device is automatically locked and put into child lock mode.

[0067] Optionally, the third preset time can be 30 seconds to 2 minutes, preferably set to 1 minute. That is, when the aerosol generating device is operating normally, if no user inhalation is detected within 1 minute, the aerosol generating device is automatically locked, entering child lock mode. In child lock mode, when the user performs another inhalation, the atomization mode of the aerosol generating device cannot be triggered, and the aerosol generating device will not operate normally. Instead, the real-time airflow rate is directly compared with a first airflow rate threshold to re-determine whether to unlock the aerosol generating device. Conversely, if the real-time airflow rate is not detected, the aerosol generating device operates normally, continuously acquiring the real-time airflow rate and continuously determining whether to enter child lock mode based on the real-time airflow rate.

[0068] Optionally, if the real-time airflow rate acquired within 1 minute is less than the second airflow rate threshold while the aerosol generator is operating normally, the aerosol generator will be automatically locked and put into child lock mode. That is, after entering child lock mode, when the user performs another inhalation action, the aerosol generator's atomization mode cannot be triggered, and the aerosol generator will not operate normally. Instead, the real-time airflow rate will be directly compared with the first airflow rate threshold to re-determine whether to unlock the aerosol generator. Conversely, if the real-time airflow rate is less than the threshold, the aerosol generator will operate normally, and the real-time airflow rate will be continuously acquired, with the system continuously determining whether to put the aerosol generator into child lock mode based on the real-time airflow rate.
