[0002] Taking e-cigarettes as an example of aerosol generation devices, e-cigarettes are non-combustible electronic atomization devices that do not produce harmful substances such as tar, thus reducing many carcinogens found in traditional tobacco. However, in related technologies, the puff counting of e-cigarettes suffers from significant statistical errors due to the influence of other factors, affecting the user experience. Summary of the Invention

[0003] In view of this, this application aims to provide a suction counting method and an aerosol generating device for improving the accuracy of suction counting in the aerosol generating device.

[0004] To achieve the above objectives, this application provides a suction counting method for an aerosol generating device. The aerosol generating device includes a switch and a sensing module. The switch is used to control the start and stop of the aerosol generating device. The suction counting method includes:

[0005] Based on the working state of the switch, determine whether the aerosol generating device is started;

[0006] The sensor module detects the user's suction characteristics.

[0007] Once the aerosol generating device is activated and the sensing module detects the suction feature, a suction count is performed.

[0008] In one embodiment, the aerosol generating device includes a control module, and the switching element includes an airflow sensor. The airflow sensor is used to detect the airflow pressure signal inside the aerosol generating device, and sends a start signal to the control module when the airflow pressure signal generated inside the aerosol generating device is detected.

[0009] In one embodiment, the suction feature includes suction movements of the user's mouth, and the sensing module includes a camera module for detecting the user's mouth movements.

[0010] In one embodiment, the aerosol generating device includes a locked mode and an unlocked mode. Before determining whether the aerosol generating device is activated based on the operating state of the switching element, the suction counting method further includes:

[0011] The camera module performs facial recognition on the user.

[0012] The user is confirmed to have switched the aerosol generating device to unlock mode via facial recognition.

[0013] In one embodiment, the suction features include the user's grip posture, grip position, and / or mouth contact state when using the aerosol generating device, and the sensing module includes a contact sensor for detecting the user's grip posture, grip position, and / or mouth contact state.

[0014] In one embodiment, the sensing module includes a lidar, and the suction feature includes the distance between the user's mouth and the lidar, wherein the lidar is at least used to detect the distance between the user's mouth and the lidar.

[0015] In one embodiment, the aerosol generating device includes an alarm module, and the suction counting method further includes:

[0016] If the suction count reaches the set suction count, the alarm module will sound an alarm.

[0017] In one embodiment, the suction counting method further includes:

[0025] This application provides a suction counting method and an aerosol generating device. The activation state of the aerosol generating device is determined by the operating status of a switching component, and a sensing module detects the user's suction characteristics. Thus, the aerosol generating device can combine the activation state and the detected suction characteristics to determine whether the user has performed suction, thereby counting the suction. By adding multiple conditions for normal user suction for judgment and operation, the possibility of false statistics due to single-condition judgment is reduced, which helps improve the accuracy of counting the number of times the user uses the aerosol generating device, thereby improving the user experience.

[0035] This application provides an aerosol generating device 100. Please refer to [link / reference]. Figures 2 to 5 The aerosol generating device 100 includes a control module 1, a switch 2, a sensing module 3, and a counting module. The switch 2 is electrically connected to the control module 1 and is used to control the start and stop of the aerosol generating device 100. The sensing module 3 is electrically connected to the control module 1 and detects the user's suction characteristics. The counting module is electrically connected to the control module 1 and is used to count suction.

[0036] Control module 1 is a module in the aerosol generating device 100 used to coordinate the operation of various modules, process sensor data, and execute control algorithms. Control module 1 can be the central processing unit of the aerosol generating device 100, and is typically composed of a microcontroller.

[0037] The switch element 2 is an electromechanical component in the aerosol generating device 100 that controls the on / off state or changes the state of the aerosol generating device 100 through various triggering conditions. The switch element 2 is electrically connected to the control module 1, and the control module 1 outputs commands to control the switch element 2. For example, the switch element 2 can be a physical button, a touch sensor, a Hall element, etc.

[0038] The sensing module 3 is a sensor system in the aerosol generating device 100 used to detect user behavior. The sensing module 3 is electrically connected to the control module 1. The sensing module 3 detects the user's suction characteristics and transmits them to the control module 1, providing input for the control module 1 to perform operations. For example, the sensing module 3 can be a pressure sensor, flow sensor, infrared sensor, etc.

[0039] The counting module is a functional unit in the aerosol generating device 100 used to realize usage data statistics. For example, the counting module can count the duration of a single suction, the average number of times used per day, the cumulative amount used, etc.

[0040] For example, please refer to Figure 2 and Figure 3The aerosol generating device 100 provided in this application has a battery bracket 4 disposed on the upper part of the inner cavity of the battery tube 6, a first connector 51 attached to the lower part of the inner cavity of the battery tube 6, a battery cell 5 attached to the other side of the first connector 51, a control module 1 disposed on a circuit board assembly 9, the circuit board assembly 9 disposed on the end face 62 of the battery tube 6 via a positioning post 61 of the battery tube 6, and a cover plate assembly 7 disposed above the circuit board assembly 9, the cover plate assembly 7 being connected to the battery tube 6 via a buckle 71.

[0041] For example, the first connector 51 can be tape.

[0042] In some embodiments, the sensing module 3 includes a camera module disposed within the camera mounting bracket 63 of the battery tube 6, and the camera module is electrically connected to the circuit board assembly 9. The switching component 2 includes an airflow sensor (also called a microphone), which is mounted within the first buffer 8. The airflow sensor and the first buffer 8 are mounted together within the mounting hole 41 on the battery bracket 4, and the airflow sensor is electrically connected to the circuit board module.

[0043] For example, the first buffer 8 can be made of silicone, rubber, or sponge, etc.

[0044] In some embodiments, please refer to Figures 2 to 5 The circuit board assembly 9 is equipped with a push-button switch 91. The push-button switch 91 is located at the middle of the upper end of the circuit board assembly 9 and is used to control the standby power-on of the aerosol generating device 100. In the standby power-on state, the power-consuming modules such as the control module 1, the switch 2, the sensing module 3, and the counting module can work normally in standby mode.

[0045] In some embodiments, a second buffer 92 is provided around the push button switch 91 to enhance the pressing and rebound feel of the push button switch 91.

[0046] For example, the second buffer 92 can be made of silicone, rubber, or sponge, etc.

[0047] In some embodiments, please refer to Figure 2 The aerosol generating device 100 includes an alarm module 11, which is a buzzer. The buzzer is electrically connected to the circuit board assembly 9 and is used to issue an alarm to remind the user.

[0048] In some embodiments, please refer to Figure 2 and 4The aerosol generating device 100 includes a screen assembly 10, which consists of a screen support 101, a second connector 102, and a screen 103. One side of the second connector 102 is connected to the inner cavity surface of the screen support 101, and the other side is connected to the screen 103. Through the screen assembly 10, various parameters of the aerosol generating device 100 can be displayed to the user, such as the number of suction cycles, battery level, heating temperature, and the remaining amount of aerosol production medium.

[0049] For example, the second connector 102 can be tape.

[0050] Here, we will use an electronic cigarette as an example to illustrate the process. An electronic cigarette is a non-combustion electronic atomization device that does not produce harmful substances such as tar, thus reducing the number of carcinogens found in traditional tobacco. To better help smokers reduce harm and quit smoking, the aerosol generating device 100 provided in this application can count the number of puffs by the user through a counting module, informing the user of the number of puffs to serve as a warning and guide the user to actively reduce the number of puffs.

[0051] This application provides a suction counting method for an aerosol generating device 100. Please refer to [link to relevant documentation]. Figures 1 to 5 The aerosol generating device 100 includes a switch 2 and a sensing module 3. The switch 2 is used to control the start and stop of the aerosol generating device 100. Please refer to [link to relevant documentation]. Figure 1 The suction counting method includes the following steps S101 to S103:

[0052] Step S101: Based on the working status of the switching device, determine whether the aerosol generating device is started.

[0053] Step S102: The user's suction characteristics are detected by the sensing module.

[0054] Step S103: If the aerosol generating device is activated and the sensing module detects a suction feature, then perform a suction count.

[0055] In step S101, the operating state of the switch 2 includes at least two states: a conducting state and a disconnected state. The conducting state means that the switch 2 connects the circuit, creating a power supply loop for the aerosol generating device 100, allowing the device to receive power and start operating. The disconnected state means that the switch 2 disconnects the circuit, interrupting the power supply to the device, leaving it in a state of not starting or stopping operation. These two states determine whether the aerosol generating device 100 can start operating and whether its related functions can be activated.

[0056] It should be noted that in some embodiments, the circuit board assembly 9 of the aerosol generating device 100 is provided with a push-button switch 91, which is used to control the standby power-on of the aerosol generating device 100. The working state of the switch 2 here refers to the on and off states of the switch 2 when the aerosol generating device 100 is in the standby power-on state. When the aerosol generating device 100 is not in standby power-on, the switch 2 itself is not powered on and cannot output the normal working state.

[0057] In step S101, the user's suction characteristics refer to a series of detectable and identifiable features and parameters related to the suction action when the user uses the device. Specific suction characteristics are not limited here; for example, they could be changes in airflow velocity or pressure inside the device caused by suction, or local temperature changes due to the suction action. It should be noted that the sensing module 3 can detect at least one suction characteristic of the user; it can detect one, multiple, or multiple characteristics and parameters simultaneously satisfying a single suction characteristic.

[0058] It should be noted that steps S101 and S102 have no temporal or logical order. When both the switch 2 and the sensing module 3 of the aerosol generating device 100 are working, the switch 2 and the sensing module 3 can detect independently.

[0059] In step S103, the suction counting operation will only be performed when both conditions are met simultaneously. That is, the suction counting operation will only be performed when it is determined that the aerosol generating device 100 is started and the sensing module 3 detects a suction feature. If the device is started but there is no suction feature, or there is a suction feature but the device is not started, or the device is not started and there is no suction feature, none of these three situations meet the requirements of normal suction, and the device will not perform suction counting.

[0060] Taking an aerosol generating device 100 as an example of an electronic cigarette, the activation of an electronic cigarette is generally controlled by an airflow sensor. In some cases, such as temperature or pressure changes caused by abnormal use of the electronic cigarette, a pressure difference may occur in the airflow sensor, which may cause the electronic cigarette to be activated falsely. However, the user is not taking a puff, and the puff count is not being recorded, which leads to errors in the statistical data of the puff count and affects the user experience.

[0061] This application provides a suction counting method for an aerosol generating device 100. The activation state of the aerosol generating device 100 is determined by the operating state of the switch 2, and the suction characteristics of the user are detected by a sensing module 3. Thus, the aerosol generating device 100 can combine the activation state and the detected suction characteristics to determine whether the user has performed suction, thereby counting the suction. By adding multiple conditions for normal user suction for judgment and operation, the possibility of miscounting under a single condition is reduced, which helps improve the accuracy of counting the number of times the user uses the aerosol generating device 100 for suction, thereby improving the user experience.

[0062] In some embodiments, the switching element 2 includes an airflow sensor, which is used to detect the airflow pressure signal within the aerosol generating device 100 and to send a start signal to the control module 1 when an airflow pressure signal is detected within the aerosol generating device 100.

[0063] An airflow sensor is a device specifically designed to sense airflow parameters in the environment, such as airflow velocity and pressure. In the aerosol generating device 100, it can accurately detect changes in airflow pressure inside the device and convert these changes into electrical signals that can be recognized by the control module 1. In the aerosol generating device 100, the airflow sensor is also referred to as a microphone.

[0064] Inside the aerosol generating device 100, when a user performs a suction action, it causes airflow inside the device, which in turn generates changes in airflow pressure. These changes are captured by the airflow sensor in the form of a signal.

[0065] The airflow sensor can be installed anywhere, such as at the device's regular air inlet or near the outlet. This allows for simultaneous monitoring of the airflow pressure at both the inlet and outlet. By comparing the data from the two sensors, control module 1 can obtain more comprehensive airflow information, such as the direction of airflow within the device and the presence of backflow. This helps to more accurately identify the user's suction actions and reduces misjudgments caused by abnormal airflow within the device (such as leaks). Simultaneously, the aerosol output status can be monitored and adjusted based on data from the outlet airflow sensor, improving the user experience.

[0066] Switch 2 employs an airflow sensor, whose primary function is to monitor the airflow pressure signal inside the aerosol generating device 100 in real time. When the user performs a normal suction action, airflow is generated within the device, causing changes in airflow pressure. Once the airflow sensor detects this airflow pressure signal, it quickly converts it into an electrical signal and sends a start signal to the control module 1. Upon receiving the start signal, the control module 1 determines, according to a preset program, that the device needs to be started, and then controls the relevant components to begin working, such as activating the heating module to heat and atomize the aerosol generating medium, ultimately achieving the generation and output of aerosol.

[0067] Compared to traditional physical button switches 91, using an airflow sensor to detect airflow pressure signals to control device activation is more suitable for the application scenarios of the aerosol generator 100. Users only need to perform a natural suction action for the device to respond quickly and start, achieving a seamless user experience. Simultaneously, based on accurate detection of airflow pressure signals, it can accurately determine whether the user has a genuine suction need, avoiding unnecessary activation due to accidental button presses, thus improving the convenience and accuracy of device use.

[0068] In some embodiments, the suction feature includes the suction action of the user's mouth, and the sensing module 3 includes a camera module for detecting the user's mouth action.

[0069] The suction action of the user's mouth refers to a series of actions performed by the user's mouth when using the aerosol generating device 100, such as the lips wrapping around the device's suction nozzle and the contraction of oral muscles to create negative pressure. These actions draw the aerosol generated by the device into the mouth. These actions are key behaviors for the user to obtain aerosols, and they have specific morphological and rhythmic characteristics that can be captured by the camera module.

[0070] Here, the sensing module 3 includes a camera module, which captures images of the user's mouth movements. The camera module utilizes its optical imaging and signal conversion capabilities to monitor the user's mouth movements in real time. When the user performs suction, the mouth exhibits specific movement patterns, such as the degree of lip opening and closing, and the contraction of the cheeks. The camera module captures these movement changes and converts them into image data. Subsequent components of the device, such as the control module 1, can analyze this image data to determine whether the user is performing a suction operation, and then execute corresponding functions based on the determination result, such as starting the device to generate aerosols or performing suction counting.

[0071] For example, a motion analysis algorithm is embedded in control module 1. This algorithm can perform deep learning analysis on the sequence of user mouth motion images captured by the camera module. It can not only identify simple sucking motions, but also further analyze more detailed features such as the force, frequency, and duration of the sucking motions. As the number of times the device is used increases, the mouth sucking motion data of each user, along with corresponding usage habits, preference settings, and other information, are stored to establish a user motion model database.

[0072] When a new user uses the device, the camera module collects their mouth movement data and compares it with existing models in the database. It attempts to match the new user with similar usage patterns and automatically adjusts the device's initial settings based on the matching results, such as the taste, concentration, and amount of aerosol generation, providing a more considerate and personalized user experience. Simultaneously, as new user data is continuously added, the database can be continuously updated and optimized, further improving the accuracy of personalized recommendations and the device's intelligence.

[0073] By directly detecting the user's suction movements through a camera module, this method is more intuitive and accurate compared to relying solely on indirect methods such as airflow or pressure. Mouth movements are a direct manifestation of suction, reducing misjudgments caused by abnormal airflow within the device or other environmental factors. This facilitates accurate identification of the user's true intentions, ensuring that relevant functions are only executed when the user actually performs a suction action, thus improving the device's operational reliability.

[0074] In some embodiments, the aerosol generating device 100 includes a locked mode and an unlocked mode. Before step S101, the suction counting method further includes the following steps S001 to S002:

[0075] Step S001: Perform facial recognition on the user using the camera module;

[0076] Step S002: Confirm that the user has switched the aerosol generating device to unlock mode through facial recognition.

[0077] Locked mode is a state of the aerosol generating device 100. In this mode, the core functions of the device (such as starting aerosol generation and suction counting) are restricted, and the user cannot operate the device normally unless a specific unlocking procedure is followed. This mode prevents unauthorized personnel from using the device, protects device data security, and avoids unnecessary misoperation.

[0078] The unlock mode is the opposite of the lock mode. After the user passes a specific authentication process (facial recognition in this embodiment), the device enters the unlock mode. In this mode, the user can use the device's various functions normally, such as starting the device to generate aerosols, performing aspiration operations, and triggering aspiration counting.

[0079] In step S001, after the camera module captures the user's facial image, it processes the image to extract facial feature points, such as facial features and sucking action features. Then, it compares these features with user facial feature templates pre-stored in the device or database to determine whether the current user is an authorized user. If the comparison is successful, the user is considered to have passed facial recognition.

[0080] In step S002, the extracted facial features are further analyzed and compared with pre-stored authorized user facial feature templates. If the comparison result shows a successful match, indicating that the user has passed facial recognition, the device will switch from locked mode to unlocked mode. Only in unlocked mode can the user further operate the device, such as activating the device via switch 2, thereby triggering subsequent functions such as suction counting.

[0081] Using facial recognition as a prerequisite for unlocking the device ensures that only authorized users can switch the device to unlock mode and use it, helping to prevent theft or unauthorized use and protecting user privacy and the security of data stored on the device. For aerosol generating devices 100 that are unsuitable for minors (such as e-cigarettes), facial recognition helps reduce the likelihood of minors accessing and using the device.

[0082] In some embodiments, the suction features include the user's grip posture, grip position and / or mouth contact state when using the aerosol generating device 100, and the sensing module 3 includes a contact sensor for detecting the user's grip posture, grip position and / or mouth contact state.

[0083] The grip posture refers to the hand position when the user holds the aerosol generating device 100, such as pinching it with the thumb and forefinger, or grasping it with the whole hand, etc.

[0084] The grip position refers to the specific contact position of the user's hand on the aerosol generating device 100, such as near the head, middle, or tail of the device.

[0085] Mouth contact status refers to the contact between the user's mouth and the device's suction nozzle when the user uses the aerosol generating device 100 for suction.

[0086] A contact sensor is a sensor that can detect the contact between objects. It determines whether there is contact and the related characteristics of contact by detecting changes in physical quantities such as pressure, capacitance, and resistance. In the aerosol generating device 100, the contact sensor is used to detect the user's grip posture, grip position, and mouth contact state, and converts this information into electrical signals and transmits it to the device's control module 1.

[0087] When a user picks up the device and begins use it, the contact sensor detects the contact information between the user's hand and the device, thereby determining the grip posture and position. During the suction action, the contact sensor can also sense the contact status between the mouth and the suction nozzle.

[0088] The contact sensor converts the detected information into identifiable signals such as electrical signals and transmits them to the control module 1 of the device. Based on these signals, the control module 1 can determine whether the user is performing a normal suction operation and can execute corresponding suction counting functions according to different detected suction characteristics.

[0089] By detecting features directly related to the user's suction action, such as grip posture, grip position, and mouth contact status, this method can more comprehensively and accurately identify whether the user is actually performing a suction operation, compared to relying solely on a single airflow or pressure detection method. It avoids misjudgments caused by factors such as abnormal airflow within the device or external environmental interference. The device only executes relevant functions when the user is performing a valid suction action, improving the accuracy and reliability of the device's operation.

[0090] In some embodiments, the sensing module 3 includes a lidar, and the suction feature includes the distance between the user's mouth and the lidar, wherein the lidar is used at least to detect the distance between the user's mouth and the lidar.

[0091] A lidar is a device that calculates the distance between an object and a radar by emitting a laser beam and measuring the time it takes for the laser beam to travel from emission to reflection after encountering an object. It utilizes the high directionality, high monochromaticity, and high energy density of laser light to achieve high-precision distance measurement. In the aerosol generating device 100, the lidar is used to detect the distance between the user's mouth and the device.

[0092] The suction feature here refers to the distance between the user's mouth and the lidar. In the application scenario of the aerosol generating device 100, the change in this distance can reflect whether the user is performing a suction action and the relevant suction status. For example, the mouth moving closer to or further away from the lidar can correspond to actions such as starting or stopping suction.

[0093] By detecting the unique suction characteristic of the distance between the user's mouth and the lidar, this method can more directly and accurately identify the user's suction actions compared to traditional detection methods that rely solely on airflow or pressure. It reduces misjudgments caused by abnormal airflow within the device (such as leaks or fluctuations) or external environmental interference (such as wind or vibration), improving the accuracy and reliability of the device's judgment of the user's suction behavior. Suction counting is only performed when the user is actually performing effective suction.

[0094] In some embodiments, the aerosol generating device 100 includes an alarm module 11, and the suction counting method further includes:

[0095] If the suction count reaches the set suction count, the alarm module will sound an alarm.

[0096] The alarm module 11 is a component of the aerosol generating device 100, and its function is to issue an alarm signal when specific conditions are met. The alarm signal can take various forms, such as a buzzer, voice prompt, flashing light, vibration, etc., to attract the user's attention.

[0097] The set number of puffs is a pre-defined value determined by the user or manufacturer based on different needs and purposes. For example, to control the frequency and dosage of use, an appropriate upper limit for the number of puffs can be set.

[0098] The aerosol generating device 100 is equipped with an alarm module 11. This device has a suction counting function, recording each suction action taken by the user. When the number of suctions counted by the device reaches a preset number, the alarm module 11 will activate and issue a corresponding alarm signal. For example, assuming the set suction count is 20 times, after the user has performed 20 suctions, the alarm module 11 will alert the user through sound, light, or vibration.

[0099] For example, multiple different suction count thresholds can be set, corresponding to different levels of alarms. For instance, when the suction count reaches 50% of the set count, the alarm module 11 issues a slight alert, such as a soft flashing light; when it reaches 80%, a more obvious alert is issued, such as intermittent beeping; and when the set suction count is fully reached, a strong alarm is issued, such as a continuous loud beep and rapid flashing lights. This allows users to understand their usage progress in advance and gradually adjust the usage frequency.

[0100] By setting a suction count and triggering an alarm when that count is reached, users can reasonably control the amount used and reduce potential health hazards caused by overuse.

[0101] In some embodiments, the suction counting method further includes:

[0102] Once the suction count has reached the set suction count, shut down the aerosol generation device.

[0103] When the aerosol generating device 100 counts the suctions, reaching the preset suction count, the device will automatically shut down. In other words, the device continuously monitors and counts the user's suction actions; once the count matches the preset suction count, the device will initiate the shutdown process, ceasing aerosol generation and other related operations. For example, assuming the preset suction count is 30, the aerosol generating device 100 will automatically shut down after the user has performed 30 suctions.

[0104] By automatically shutting down the device when a set number of puffs is reached, the amount of medication used by the user can be controlled, reducing the risk of excessive intake of harmful substances and thus protecting the user's health.

[0105] In some embodiments, the aerosol generating device 100 includes an input module, which is at least used to set a set number of suctions for the aerosol generating device 100.

[0106] The input module is a component of the aerosol generating device 100. Its main function is to receive external input information and convert it into signals that the device can recognize and process. It provides a way for users or other external systems to interact with the aerosol generating device 100 in order to set and adjust certain parameters or functions of the device.

[0107] Here, the input module is used to set the set number of aspirations for the aerosol generating device 100. Depending on the intended use, such as controlling the user's frequency of use, ensuring appropriate dosage intake, or meeting specific usage rules, a specific number of aspirations can be predetermined. This number can be set by the user according to their own needs, or by the manufacturer based on product characteristics and relevant standards.

[0108] For example, the input module is equipped with wireless connectivity features such as Bluetooth and Wi-Fi, enabling it to connect to external devices such as smartphones and tablets. Users can set the number of puffs on their phones or other devices through a specially developed application (APP), utilizing the larger screen 103 and richer interactive interface of the phone to provide a more convenient and personalized setting experience. Simultaneously, the APP can also record the user's usage history and setting preferences, allowing users to easily view and adjust them at any time.
