That is, the information collection process / feature extraction process complies with the requirements of laws and regulations and does not belong to an act that harms the public interest.

[0067] The current configuration of aerosol devices does not have a safety protection function. Usually, any user can use the aerosol device as long as they come into contact with it, and it is impossible to restrict the use of aerosol devices by underage users, which will affect the physical health of underage users.

[0068] In view of the above problems, the embodiment of the present application provides a control method for an aerosol device. By collecting specific features of the user, the age of the user is evaluated to determine whether the user meets the device usage conditions of the aerosol device, so as to determine whether to operate the aerosol device. In this way, the aerosol device has a safety protection function, and other underage users can be prohibited from using the aerosol device, improving the safety of using the aerosol device.

[0069] The following introduces the control method of the aerosol device in the embodiment of the present application through specific embodiments.

[0070] Figure 1 It is a schematic structural diagram of a control system of an aerosol device according to an embodiment of the present application. This control system is applicable to the control method of the aerosol device in the embodiment of the present application. This control system includes an aerosol device 110 and a terminal device 120 that are communicatively connected. The aerosol device 110 includes an image collector 111.

[0071] The image collector 111 is configured to collect a first object image in response to a control instruction of the aerosol device 110. The first object image includes a first object feature corresponding to the first object.

[0072] The aerosol device 110 is configured to, when it is detected that the aerosol device is in a state of waiting to be heated, perform an age assessment on the first object based on the first object feature to obtain a first age prediction result corresponding to the first object; when the first age prediction result does not reach the age threshold, trigger a first indication information, and the first indication information is used to indicate that the first object does not meet the device usage conditions.

[0073] The aerosol device 110 may be a heat-not-burn device or an electronic atomizer, etc.

[0074] The image collector 111 can be a near-infrared light camera module, a laser scanning imaging module, a micro complementary metal-oxide-semiconductor (CMOS) image sensor, etc. The embodiments of the present application do not specifically limit the specific type of the image collector 111. In the embodiments of the present application, a near-infrared light camera module is taken as an example.

[0075] The image collector 111 can be integrated on the top or side of the aerosol device 110. Through the natural holding posture of the user during use, non-contact retinal imaging of the user can be performed, and then identity verification and age assessment can be carried out subsequently. There is no need for the user to specifically find the image collector 111 and pose for retinal scanning, and the acquisition of retinal images without perception can be realized, thereby improving the user experience of using the aerosol device 110.

[0076] The image collector 111 is specifically configured to collect a first object image of a first object; call an image processing algorithm or a deep learning model to extract object features in the first object image, and send the object features to the aerosol device 110, so that the aerosol device 110 can send the object features to a terminal device and / or predict the age corresponding to the object features in the subsequent process. The object features may include the blood vessel distribution pattern of the retina of the first object, the thickness of the retinal layer, and the structural features of the optic disc and macula area.

[0077] The image collector 111 further includes an image preprocessing module, which is used to perform preprocessing operations such as denoising, enhancement, and alignment on the collected first object image, so as to extract the first object features in the preprocessed first object image.

[0078] Continuing to combine Figure 1 , the aerosol device 110 includes a first processor 112 and a power supply component 113. The first processor 112 is used to execute all steps that the aerosol device 110 can perform, and the power supply component 113 is used to supply power to the aerosol device 110 to enable the aerosol device 110 to operate.

[0079] The first processor 112 may be a Central Processing Unit (CPU), a Microcontroller Unit (MCU), a Digital Signal Processor (DSP), an Application-Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), or a System-on-Chip (SoC), etc., or may be other general-purpose processors. The embodiments of the present application do not limit the specific type of the first processor.

The aerosol device 110 is specifically configured to control at least one of the vibrator 114, the indicator light 115, the display screen 116, or the speaker 117 to output indication information.

The embodiments of the present application do not make specific limitations. In the embodiments of the present application, a Bluetooth component is taken as an example.

[0082] The aerosol device 110 further includes a storage component 119 for storing device data of the aerosol device 110. The device data refers to data related to the operation, function realization, and user interaction of the aerosol device, and may include system configuration information such as the hardware configuration, software program, and user behavior records of the aerosol device 110, as well as log information. For example, the system configuration information may include the temperature adjustment algorithm, suction detection algorithm, image processing algorithm, and model parameters of the deep learning model of the aerosol device 110. The log information may include the usage duration, current heating temperature, and remaining power of the aerosol device. The storage component 119 may be a flash register or an electrically erasable programmable read-only memory (EEPROM), etc., and the embodiments of the present application do not make specific limitations.

[0083] The aerosol device 110 is further configured to send the first object feature to the terminal device 120; receive the information verification result sent by the terminal device 120; start the heating element when it is detected that the information verification result meets the verification success condition; and enter the step of evaluating the age of the first object based on the first object feature when it is detected that the information verification result meets the verification failure condition.

[0084] The terminal device 120 is configured to verify the identity of the first object based on the first object feature and at least one object feature sample, and return the information verification result to the aerosol device 110.

[0085] The terminal device 120 may be a device such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA). The embodiments of the present application do not impose any limitations on the specific type of the terminal device.

The second processor 121 is configured to execute the steps performed by the terminal device 120, and the second communication component 122 is configured to establish a communication connection with the first communication component to communicatively connect the terminal device 120 with the aerosol device 110.

[0087] The terminal device 120 is further connected to a cloud server, and the terminal device 120 is further configured to store the object feature samples corresponding to at least one authorized object of the aerosol device in the cloud server.

[0088] Figure 2It is a schematic flowchart of a control method for an aerosol device according to an embodiment of the present application. This method is applied to an aerosol device, which can be Figure 1 the aerosol device 110 shown in Figure 2 As shown, the method includes the following steps:

[0089] S101, when it is detected that the aerosol device is in a state to be heated, collect a first object image.

[0090] Among them, the first object image includes first object features corresponding to the first object. The first object is the user currently using the aerosol device. The first object image can be used not only for age assessment but also for identity verification. For example, the first object image can be the retinal image, face image, iris image, etc. of the first object.

[0091] In the embodiment of the present application, the first object image is taken as the retinal image of the first object as an example. This is because the retina, as a light-sensitive tissue inside the user's eye, has the characteristic that its structure and function change with age. Therefore, the age of the user can be predicted based on the characteristics such as the structure of the retina in the retinal image. Generally speaking, the changes in the structure of the retina with age mainly include four situations: blood vessel changes, retinal layer thickness changes, pigment changes, and other changes. Blood vessel changes refer to the changes in the diameter, branching pattern, and curvature of the retinal blood vessels with age; retinal layer thickness changes refer to the thinning of the thickness of some retinal layers (such as the nerve fiber layer) with age; pigment changes refer to the changes in the number and distribution of retinal pigment epithelial cells with age; other changes include the structure of the macula area and the morphology of the optic disc, etc., which are related to age changes. In order to accurately evaluate the age corresponding to the user of the aerosol device, the first object features at least include the blood vessel distribution pattern of the retina of the first object, the retinal layer thickness, and the structural features of the optic disc and macula area.

[0092] The state to be heated includes at least the following two situations: 1. The aerosol device is in the powered-on state and has not started its own heating element; 2. The aerosol device is awakened from the sleep state and has not started its own heating element. The aerosol device will be awakened from the sleep state when it detects the insertion of the aerosol matrix, a suction action on the aerosol device, the aerosol device being picked up, or a specific button on itself being pressed.

[0093] When the aerosol device detects that it is currently in a state to be heated, it will control its own image collector to collect the first object image of the first object, and control the image collector to extract the first object features from the first object image.

[0094] In one example, taking the image collector as a near-infrared light camera module, the aerosol device will control the image collector to emit near-infrared light to scan the eyes of the first object. The near-infrared light is reflected back to the image collector through the user's eyes. The image collector can process the reflected near-infrared light to generate a retinal image, and perform preprocessing operations such as denoising, enhancement, and alignment on the generated retinal image to obtain the first retinal image of the first object, which is the first object image. After obtaining the first retinal image, the image collector will call an image processing algorithm or a deep learning model to extract the first object features from the first retinal image. In this way, the aerosol device obtains the first object features and the first object image.

[0095] The image processing algorithm can be a feature extraction algorithm based on the Gabor filter, a feature extraction algorithm based on wavelet transform, or a feature extraction algorithm based on morphological operations, etc. The deep learning model can be a U-shaped Convolutional Neural Network (U-Net), a Residual Network (ReNet), or a Mask Region-based Convolutional Neural Network (Mask R-CNN). The specific image processing algorithm and deep learning model can be selected based on the limitations of the hardware conditions of the aerosol device, and the embodiments of the present application do not make specific limitations.

[0096] S102. Perform age assessment on the first object based on the first object features to obtain the first age prediction result corresponding to the first object.

[0097] The aerosol device will call an age prediction model to predict the age corresponding to the first object features and output the predicted age result, that is, the first age prediction result. The age prediction model includes the function of predicting the age of the user of the retina based on the features in the retinal image. The age prediction model can be a Graph Neural Network (GNN), a Convolutional Neural Network (CNN), a Generative Adversarial Network (GAN), or a MobileNetV3 model improved by transfer learning (the full name of MobileNetV3 is Mobile Network Version 3, which is a lightweight CNN architecture). The specific selection of the age prediction model can be based on the hardware conditions of the aerosol device, and the embodiments of the present application do not make specific limitations.

[0098] S103. When the first age prediction result does not reach the age threshold, trigger the first indication information.

[0099] Among them, the first indication information is used to indicate that the first object does not meet the device usage conditions. The age threshold is the age at which aerosol devices can be used as stipulated in the circulation area of aerosol devices. For example, it can be 18 years old, 20 years old, etc. The device usage conditions include that the age of the object using the aerosol device is greater than or equal to the age threshold.

[0100] When the aerosol device detects that the first age prediction result is less than the age threshold, it determines that the first object does not meet the device usage conditions. The aerosol device will control at least one of its vibrator, indicator light, display screen, or speaker to output the first indication information, and forcefully shut down the aerosol device to prevent underage users from using the aerosol device.

[0101] In one implementation, when the first age prediction result reaches the age threshold, start the heating element of the aerosol device. The aerosol device starts the heating element only when it detects that the first age prediction result corresponding to the first object is greater than or equal to the age threshold, which can ensure that the device operates normally only when the user's age meets the device usage conditions, providing safety protection measures for the use of the aerosol device.

[0102] Combined with Figure 3 Taking the application scenario shown as an example, taking the aerosol device as an electronic atomizer, the electronic atomizer was originally in a dormant state. When a user U uses the electronic atomizer, the electronic atomizer is awakened by operations such as pressing a button or inserting a herbal stick (an example of an aerosol matrix). Subsequently, the electronic atomizer enters S11, detects an external interruption wake-up device (an example of detecting that the aerosol device is in a state to be heated), and starts the retina scanning module (an example of an image collector) to scan the eyes of user U (an example of the first object) to obtain the retina image of user U, and extracts the biological information (an example of the characteristics of the first object) in the retina image. This biological information includes the blood vessel distribution pattern, the thickness of the retina layer, and the structural characteristics of the optic disc and macula area. Then in S14, the electronic atomizer calls the age prediction model through the retina detection module, inputs the biological information into the age prediction model. In S15, the electronic atomizer calls the age conversion function through this age prediction model to predict the real age A of user U corresponding to this biological information (an example of the first age prediction result). In S16, it is judged whether the real age A meets the specified age range (an example of the age threshold, that is, detecting whether the real age reaches the age threshold). If it meets, it enters S17. If it does not meet, it is determined that user U is an underage user (an example of the first object not meeting the device usage conditions), and the electronic atomizer will vibrate the vibrator (an example of triggering the first indication information) and shut down.

[0103] In an embodiment of the present application, when it is detected that the aerosol device is in a state to be heated, a first object image including the first object features is collected, and the age of the first object is evaluated based on the first object features to obtain a first age prediction result. When the first age prediction result does not reach the age threshold, the aerosol device is directly turned off and a first indication information for indicating that the first object does not meet the device usage conditions is output, which can limit the usage age of the user of the aerosol device, realize the safety protection of the aerosol device, and improve the safety of using the aerosol device.

[0104] To further improve the safety of the aerosol device, as Figure 4 shown in the flowchart of another control method of the aerosol device according to the embodiment of the present application, the method further includes the following steps:

[0105] S201, when it is detected that the aerosol device is in a state to be heated, collect a first object image.

[0106] Among them, a communication connection is established between the aerosol device and the terminal device, and the aerosol device includes a heating element.

[0107] At least one object feature sample of the aerosol device is stored in the terminal device, and the authorized objects corresponding to the at least one object feature sample meet the device usage conditions. The object feature sample is the object feature extracted from the object image of the authorized object, and the object feature sample includes the blood vessel distribution pattern of the retina of the authorized object, the thickness of the retinal layer, and the structural features of the optic disc and macula area. It can be understood that the authorized object is a user who can normally use the aerosol device (or has specific operation permissions for the aerosol device).

[0108] For details of S201, reference can be made to Figure 2 S101 in the shown embodiment, which will not be elaborated here.

[0109] In one implementation, before evaluating the age of the first object based on the first object features, the method further includes S202 to S204:

[0110] S202, send the first object features to the terminal device, and the terminal device is used to verify the object information of the first object based on the first object features and the object feature samples, obtain an information verification result corresponding to the first object, and feedback the information verification result to the aerosol device.

[0111] The aerosol device can send the first object feature to the terminal device to trigger the terminal device to verify whether the first object is an authorized object of the aerosol device, that is, to verify the object information of the first object (and verify the identity of the first object), and return the information verification result to the aerosol device. In this way, after receiving the information verification result, the aerosol device can parse whether the information verification result of the first object meets the verification success condition. This method of identity verification enables the aerosol device to only be responsible for feature extraction, image acquisition and transmission, without the need to perform complex feature retrieval to verify the identity, and without the need to set up complex hardware in the aerosol device, which can save the production cost of the aerosol device. In addition, the identity verification is the responsibility of the terminal device, and the high computing power of the terminal device can be used to achieve efficient identity authentication.

[0112] The following describes the process of the object information of the first object verified by the terminal device. When the terminal device receives the first object feature, it will match the first object feature with each object feature sample; when the terminal device detects that there is an object feature sample that matches the first object feature successfully, it determines that the information verification result meets the verification success condition; when the terminal device detects that there is no object feature sample that matches the first object feature, it determines that the information verification result meets the verification failure condition.

[0113] In one implementation, the first object image is the retinal image of the first object, and the first object feature is the age-related feature extracted from the retinal image of the first object. In this way, when verifying the identity of the first object, the object feature is extracted from the retinal image, and the retinal image is usually dynamically imaged. Based on this, it can naturally resist forgery attacks such as photos or three-dimensional masks, thereby improving the reliability and accuracy of identity verification.

[0114] S203, Receive the information verification result sent by the terminal device.

[0115] S204, When it is detected that the information verification result meets the verification success condition, start the heating element.

[0116] When the aerosol device detects that the information verification result meets the verification success condition, the aerosol device will start its own heating element so that it can enter the preheating operation and heat the aerosol matrix in the aerosol device. In this way, the aerosol device starts its own heating element when the user meets the verification success condition, which can effectively reduce the probability of other users using the aerosol device, ensure the hygiene and safety of the aerosol device, make the aerosol device unique to the real user of the aerosol device, and improve the user experience of using the aerosol device.

[0117] When current aerosol devices are in use, they often heat the aerosol matrix based on a default temperature curve or the most recently set temperature curve. However, the most recently set temperature curve may not be set by the actual user of the aerosol device, and both this temperature curve and the default temperature curve may not conform to the usage habits of the actual user of the aerosol device.

[0118] To enable the aerosol device to adapt to the user's usage habits and improve the user's personalized experience of the aerosol device, a schematic flowchart of starting a heating element in one implementation manner. Starting the heating element includes the following steps (1) to (3):

[0119] Step (1), receiving the first identification information corresponding to the first object sent by the terminal device.

[0120] Among them, the terminal device stores the identification information corresponding to the authorized object. The user's identification information can be the user's number, name, account, etc., and the embodiments of the present application do not make specific limitations. The object feature sample corresponding to each authorized object stored in the terminal device will be associated with the identification information of the authorized object.

[0121] When the aerosol device detects that the information verification result meets the verification success condition, it will send a request to the terminal device to obtain the identification information corresponding to the first object feature. After receiving the request, the terminal device will search for the identification information corresponding to the object feature sample that matches the first object feature from the identification information associated with the object feature sample stored, and return the found identification information to the aerosol device as the first identification information.

[0122] In one implementation manner, it can also be that when the terminal device detects an object feature sample that matches the first object feature, it obtains the identification information corresponding to the object feature sample, and packs and sends the identification information and the information verification result to the aerosol device. In this way, the aerosol device can obtain the first identification information.

[0123] Step (2), based on the first identification information, determining the first temperature curve corresponding to the first object from the first object relationship.

[0124] Among them, the aerosol device stores the first object relationship, and the first object relationship includes the temperature curve corresponding to the identification information of each authorized object.

[0125] The aerosol device will search for the temperature curve corresponding to the first identification information from the first object relationship, and use the found temperature curve as the first temperature curve corresponding to the first object.

[0126] Step (3), based on the first temperature curve, controlling the heating element to heat the aerosol matrix in the aerosol device.

[0127] Among them, the aerosol device includes a heating element. The temperature curve refers to the dynamic trajectory of the temperature of the heating element changing with time during operation. The aerosol device can dynamically adjust the input power of the heating element and thus change the temperature curve of the heating element by adjusting the duty cycle of the Pulse Width Modulation (PWM) signal.

[0128] After determining the first temperature curve, the aerosol device outputs a PWM signal to heat up the heating element, and calls the Proportional-Integral-Derivative (PID) algorithm. Based on the difference between the temperature in the first temperature curve and the actual temperature of the heating element at different times, the PWM signal is dynamically adjusted to make the trajectory of the temperature of the heating element changing with time conform to the first temperature curve.

[0129] In the above technical solution, after the aerosol device detects that the verification of the first object meets the success condition, it obtains the first identification information corresponding to the first object from the terminal device, queries the first temperature curve suitable for the first object from the first object relationship based on the first identification information, and controls the heating element to heat the aerosol matrix of the aerosol device based on the first temperature curve. In this way, after identifying the authorized user of the aerosol device, the temperature curve commonly used by this user can be automatically collected for operation, realizing personalized heating for different user usage habits, thereby improving the adaptability of the aerosol device.

[0130] In one implementation, the method further includes the following steps (31) to (34):

[0131] Step (31), when a suction action is detected, collect a second object image of the aerosol device at a first moment.

[0132] Among them, the second object image includes the second object features of the second object of the aerosol device. The second object is the user using the aerosol device at the first moment, and the first moment is the moment when the suction action is detected.

[0133] When the aerosol device detects a suction action, it controls its own image collector to collect a second object image of the second object, and controls the image collector to extract the second object features from the second object image. Specifically, it is similar to S101 in the illustrated embodiment and will not be elaborated here. Figure 2 Similar to S101 in the illustrated embodiment, it will not be elaborated here.

[0134] In one implementation, an aerosol device includes an airflow sensor that can sense changes in the airflow in the aerosol device when the user sucks. Based on the data sensed by the airflow sensor, the aerosol device can detect a sucking action on the aerosol device.

[0135] In one implementation, the aerosol device includes a microphone, which is a sensor that converts sound signals into electrical signals. The sound and airflow changes generated when the user of the aerosol device sucks are sensed by the microphone. Based on the data sensed by the microphone, the aerosol device can detect a sucking action on the aerosol device.

[0136] In one implementation, the aerosol device includes an infrared sensor that can emit and receive infrared rays. When the user sucks, when the user's lips approach or block the infrared light, the intensity of the light received by the infrared sensor changes. Based on the data sensed by the infrared sensor, the aerosol device can detect a sucking action on the aerosol device.

[0137] In one implementation, the aerosol device includes a pressure sensor. When the user sucks, the pressure in the airflow channel of the aerosol device changes, and the pressure sensor can sense this pressure change. Based on the data sensed by the pressure sensor, the aerosol device can detect a sucking action on the aerosol device.

[0138] Step (32): Send the second object feature to the terminal device, which is used to compare the first object feature with the second object feature and send the comparison result to the aerosol device.

[0139] After the aerosol device sends the second object feature to the terminal device, the terminal device will compare whether the first object feature (or the object feature sample matching the first object feature) is consistent with the second object feature and return the comparison result to the aerosol device.

[0140] Step (33): Receive the comparison result sent by the terminal device.

[0141] The aerosol device can receive the comparison result sent by the terminal device through its own communication component.

[0142] Step (34): When it is detected that the comparison result is that the first object feature does not match the second object feature, lock the aerosol device and output a second indication message.

[0143] Among them, the second indication message is used to prompt that the authenticated user of the aerosol device is different from the user in use. The authenticated user is the user whose information verification result meets the verification success condition before the first moment, and the user in use is the user who uses the aerosol device at the first moment. In this scenario, the authenticated user is the first object and the user in use is the second object.

[0144] The aerosol device can control at least one of its indicator light, display screen, vibrator or speaker to output second indication information and stop operating the heating element.

[0145] In the case where the comparison result is that the first object feature matches the second object feature, return the step of acquiring the second object image of the aerosol device.

[0146] In the above technical solution, after the compliance verification of the first object is successful, the aerosol device will collect the second object features of the second object (i.e., the current user) and send them to the terminal device, so that the terminal device compares the first object features with the second object features and sends the comparison result to the aerosol device, so as to verify whether the second object using the aerosol device is the first object during authentication, that is, after the authorized object completes the verification of the object information, verify whether the authorized object of the aerosol device has changed, and lock the aerosol device in time and output the second indication information. The purpose of detecting the mid-way replacement of the user of the aerosol device during the normal use of the aerosol device is realized, preventing the situation that unauthorized objects other than the aerosol device use the aerosol device midway, and also being able to timely discover and prevent the situation that users who do not meet the device usage conditions use the aerosol device midway, further improving the usage safety of the aerosol device.

[0147] In one implementation, the aerosol device also stores the physiological age corresponding to each authorized object. Before controlling the heating element to heat the aerosol matrix in the aerosol device based on the first temperature curve, the method further includes the following steps:

[0148] In the case where the information verification result is detected to meet the compliance verification success condition, query the first physiological age corresponding to the first object based on the first identification information;

[0149] Evaluate the age of the first object based on the first object features to obtain the first age prediction result corresponding to the first object;

[0150] Determine the health risk level of the first object based on the difference between the first age prediction result and the first physiological age;

[0151] When the health risk level reaches the risk level threshold, trigger the fifth indication information, and the fifth indication information is used to prompt that the first object has a health risk.

[0152] Among them, the health risk level is used to represent the health degree of the authorized object of the aerosol device, and the physiological age corresponding to each authorized object in the aerosol device is associated with the identification information of the authorized object.

[0153] The first object feature of the first object often can reflect the physical health status of the first object. When there is a health risk for the first object, the first object feature often also changes, which will affect the first age prediction result determined based on the first object feature. Therefore, the health risk level of the first object can be determined based on the difference between the physiological age of the first object and the first age prediction result.

[0154] In one example, the health risk level can be divided into two types: primary health and secondary health. The risk level threshold can be the level that represents a weaker health degree among all health risk levels. For example, if the health degree represented by primary health is higher than that represented by secondary health, the risk level threshold can be secondary health; otherwise, the risk level threshold can be primary health. In this example, it is taken that the health degree represented by primary health is higher than that represented by secondary health.

[0155] When the aerosol device detects that the information verification result of the first object meets the verification success condition, it means that the first object is an authorized object of the aerosol device. The aerosol device can find the corresponding first physiological age based on the first identification information. After the aerosol device obtains the first age prediction result, the aerosol device will determine the difference result between the first age prediction result and the first physiological age, and determine whether this difference result is within the preset age range. If the difference result is within the preset age range, it is determined that the health risk level of the first object is primary health; if the difference result is greater than the maximum value in the preset age range, it is determined that the health risk level of the first object is primary health. At this time, the aerosol device detects that the health risk level reaches the risk level threshold. The aerosol device can control at least one of its vibrator, indicator light, display screen, or speaker to output the fifth indication information.

[0156] In one example, the health risk level can also be set to more than two levels, and each level corresponds to a specific age interval. The aerosol device can determine the health risk level of the first object according to the interval where the difference result between the first age prediction result and the first physiological age is located, and then determine whether to trigger the fifth prompt information.

[0157] For example, four health risk levels can be set. The age intervals corresponding to each health risk level can be as shown in Table 1 below, and the risk level threshold can be set to tertiary health.

[0158] Table 1

[0159] Health risk level Level 1 health Level 2 health Level 3 health Level 4 health Age range [0,2] (2,4) [4,5] (5,∞)

[0160] The first age prediction result determined by the aerosol device is 28 years old, while the first physiological age of the first subject is 24 years old. The difference between the first age prediction result and the first physiological age is 4 years. Then, the aerosol device can determine that the health risk level of the first subject is level three health, thereby locking the aerosol device and outputting the fifth indication information.

[0161] In the above technical solution, when the verification result of the first subject meets the verification success condition, the aerosol device can determine the health risk level of the first subject based on the difference between the first age prediction result corresponding to the first subject and the first physiological age. When the health risk level reaches the risk level threshold, the aerosol device is locked and the fifth indication information for prompting that the first subject has a health risk is output, realizing the service of health detection for users based on the difference between the real age and the evaluated age during the process of users using the aerosol device, and giving timely warnings, which can improve the use experience of the aerosol device and ensure the physical health of users.

[0162] Considering that the relevant characteristics of the retina in the retinal image of the user of the aerosol device will change with the growth of the user's age and the change of the health status, and the sensor of the aerosol device will also age over time, which will lead to changes in the collected object characteristics, resulting in the failure of identity recognition of the authorized object and affecting the user's use experience. In order to further improve the accuracy of identity recognition of the aerosol device and thus improve the user's use experience. In one implementation, as Figure 5 shown, the method further includes the following S301 to S303:

[0163] S301, when it is detected that the information verification result meets the verification success condition, count the first usage duration of the first subject using the aerosol device.

[0164] Among them, when the information verification result of the first subject meets the verification success condition, the first object feature sample corresponding to the first subject is included in the object feature samples corresponding to each authorized object of the aerosol device.

[0165] The aerosol device stores the historical usage duration corresponding to the identification information of each authorized object, and the historical usage duration represents the cumulative usage duration after the authorized object last used the aerosol device.

[0166] When it is detected that the information verification result meets the verification success condition, the aerosol device obtains the first identification information of the first object, and finds out the current historical usage duration corresponding to the first object according to the first identification information; after the aerosol device starts the heating element, it will use its own timer to start counting its working duration from 0 until it detects that the heating element cools down to the ambient temperature, and clears the timing of the timer. The ambient temperature is the temperature of the environment where the aerosol device is located; the aerosol device will determine the total result between the found historical usage duration and the current working duration as the first usage duration.

[0167] S302, when it is detected that the first usage duration reaches the preset duration threshold, output a prompt message.

[0168] Among them, the prompt message is used to indicate re-entering the object characteristics. When the first usage duration is greater than or equal to the preset duration threshold, the first usage duration reaches the preset duration threshold; when the first usage duration is less than the preset duration threshold, the first usage duration does not reach the preset duration threshold. The preset duration threshold can be 1 year, 6 months, 3 months, 1000 hours, etc.

[0169] The aerosol device will compare the first usage duration with the preset duration threshold to determine whether the first usage duration reaches the preset duration threshold. When the first usage duration reaches the preset duration threshold, in addition to outputting a prompt message, the aerosol device will also clear the historical usage duration and the first usage duration corresponding to the first object; when the first usage duration does not reach the preset duration threshold, the aerosol device will update the value of the historical usage duration corresponding to the first object to the value of the first usage duration for the next statistic.

[0170] In order to save the memory space and computing power resources of the aerosol device, in one implementation, the historical usage duration corresponding to the identification information of each authorized object can be stored in the terminal device. When it is detected that the information verification result meets the verification success condition, the aerosol device can send the counted working duration to the terminal device, so that the terminal device finds out the current historical usage duration corresponding to the first object based on the first identification information, and determines the total result between the historical usage duration and the received working duration as the first usage duration, and compares the size result between the first usage duration and the preset duration threshold, and returns the comparison result to the aerosol device. In this way, the aerosol device can detect whether the first usage duration reaches the preset duration threshold based on the received comparison result.

[0171] It can be understood that when the terminal device determines that the first usage duration is greater than or equal to the preset duration threshold, the terminal device will clear the historical usage duration and the first usage duration corresponding to the first object. Conversely, when the first usage duration is less than the preset duration threshold, the terminal device will update the value of the historical usage duration corresponding to the first object to the value of the first usage duration.

[0172] After a user reaches a certain age, their retina will experience physiological degeneration, and characteristics such as the blood vessel distribution pattern in the retinal image will change within a short period of time. In addition, the user's health status will also affect the changes in characteristics such as the blood vessel distribution pattern in the retinal image. In order to more timely save the latest retinal characteristics (i.e., object characteristic samples) of the user (i.e., the authorized object) of the aerosol device to further improve the accuracy of identity authentication. In one implementation, the terminal device can also detect whether the first usage duration reaches the preset duration threshold through the following process:

[0173] Obtain the total number of times the health risk level of the first object reaches the risk level threshold and the first physiological age;

[0174] Based on the relationship between the total number of times and the preset number interval, determine the number weight corresponding to the first object;

[0175] Based on the magnitude relationship between the first physiological age and the preset age, determine the age weight corresponding to the first object;

[0176] Determine the product result of the number weight, the age weight, and the first usage duration;

[0177] When it is detected that the product result is greater than or equal to the constrained preset duration threshold, determine that the first usage duration reaches the preset duration threshold.

[0178] The terminal device stores the number weights corresponding to multiple number intervals. It can be understood that the number weights corresponding to different number intervals can be set based on the actual application situation, and the embodiments of the present application do not make specific limitations. The preset age is the age at which the characteristics such as the blood vessel distribution pattern of the user's retina change significantly. For example, 35 years old or 40 years old, or it can also be set according to the age range of the characteristics of the user's retina in the circulation area of the aerosol device, and the embodiments of the present application do not make specific limitations. The number weight and the age weight are greater than or equal to 1. When the first physiological age is less than or equal to the preset age, the terminal device can determine that the age weight is 1.

[0179] In one example, the number weights corresponding to multiple number intervals can be as shown in Table 2 below:

[0180] Table 2

[0181] Total number of times [0,1] (1,3] (3,5] (5，∞] Weight of the number of times 1 1.1 1.2 1.5

[0182] When the first physiological age is less than or equal to the preset age, the terminal device can determine that the age weight is 1. When the first physiological age is greater than the preset age, the terminal device can determine that the age weight is greater than 1, for example, it can be 1.1, 1.2 or 1.3, etc. In one example, when the first physiological age is greater than the preset age, the age weight can also be determined based on whether the number weight is greater than 1. If the number weight is greater than 1, the value of the age weight can be determined as the value of the number weight. If the number weight is equal to 1, the age weight can be determined as the smallest number weight value other than 1, such as 1.1 in Table 2.

[0183] When the fifth indication information is triggered, the aerosol device will send a message to the terminal device to prompt that the health risk level of the first object has reached the risk level threshold. The terminal device can then count the total number of times the health risk level of the first object has reached the risk level threshold.

[0184] For example, taking the preset duration threshold as 800 hours and the preset age as 35 years old, the first usage duration determined by the terminal device is 500 hours, and the total number of times is 5 times. Based on Table 2, the corresponding number weight is 1.2, and the first physiological age is 36 years old. The corresponding age weight can be 1.2. When judging whether the first usage duration reaches the preset duration threshold, the terminal device will first determine 500*1.2*1.2=720 hours. 720 hours is less than 800 hours. The terminal device determines that the first usage duration does not reach the preset duration threshold. If the preset duration threshold is 700 hours, the terminal device determines that the first usage duration reaches the preset duration threshold.

[0185] In this technical solution, the corresponding number of times weight and age weight are determined based on the total number of times the health risk level of the first object reaches the risk level threshold and the first physiological age, and whether the first usage time reaches the preset time threshold is determined based on the product of the number of times weight, the age weight and the first usage time. The difference between the first usage time and the preset time threshold is affected by the age and health status of the user of the aerosol device, so that the update timing of the first object feature sample can be captured more timely and accurately, thereby timely updating the first object feature sample, thereby improving the accuracy of subsequent identity authentication.

[0186] S303: Collect a fourth object feature of the first object, and send the fourth object feature to a terminal device, where the terminal device is used to update the first object feature sample corresponding to the first object to the fourth object feature.

[0187] When the first usage duration reaches a preset duration threshold, the aerosol device will collect the current object image of the first object through its own image collector and extract the object features therefrom. The object features are the fourth object features, and the fourth object features will be sent to the terminal device so that the terminal device can update the first object feature sample.

[0188] In the technical solutions of S301 to S303, after the first object meets the verification success condition, the first usage duration of the first object using the aerosol device will also be counted. In the case where the first usage duration reaches the preset duration threshold, the object features of the first object will be re-entered, and the terminal device will update the first object feature sample corresponding to the first object, so as to realize the timely update of the object feature sample corresponding to the authorized object of the aerosol device based on the usage duration. In this way, when the next authorized object uses the aerosol device, the identity of the authorized object can be verified based on the latest object feature sample, thereby improving the accuracy of the identity recognition of the aerosol device and further improving the user experience.

[0189] In one implementation manner, the step of evaluating the age of the first object based on the first object features to obtain the first age prediction result corresponding to the first object includes the following S205:

[0190] S205, in the case where it is detected that the information verification result meets the verification failure condition, the step of evaluating the age of the first object based on the first object features to obtain the first age prediction result corresponding to the first object.

[0191] S206, in the case where the first age prediction result does not reach the age threshold, trigger the first indication information, and the first indication information is used to indicate that the first object does not meet the device usage conditions.

[0192] For details of S205 to S206, reference can be made to Figure 2 S102 to S103 in the embodiments shown, which will not be elaborated here.

[0193] In one implementation manner, continue to combine Figure 4 , in the case where it is detected that the first age prediction result reaches the age threshold, the method further includes S207 to S210:

[0194] S207, in the case where it is detected that the first age prediction result reaches the age threshold, send the first request information to the terminal device.

[0195] Among them, the first request information is used to instruct the terminal device to determine whether to use the first object as an authorized object of the aerosol device.

[0196] The aerosol device sends the first request information to the terminal device. When the terminal device receives the first request information, it will display (on its own display screen) the specified prompt information, which is used to prompt the authorized object to select whether to authorize the first object; the terminal device responds to the selection of the authorized object, generates and sends the first response result to the aerosol device. It should be noted that when the authorized object selects the first object as an authorized object of the aerosol device, the terminal device will also generate the identification information corresponding to the first object and store the identification information associated with the characteristics of the first object for verifying the identity of the first object next time.

[0197] S208, Receive the first response result returned by the terminal device based on the first request information.

[0198] Among them, the first response result indicates whether to add the first object to the authorized objects of the aerosol device.

[0199] S209, When it is detected that the first response result is to add the first object to the authorized objects of the aerosol device, start the heating element.

[0200] When the aerosol device detects that the first response result is to add the first object to the authorized objects of the aerosol device, it will start its own heating element so that the first object can use the aerosol device for suction. The specific process of the aerosol device heating its own heating element can be to directly start the heating element for heating, or to start the heating element for heating based on the first temperature curve corresponding to the first object.

[0201] S210, When it is detected that the first response result is that the first object is not added to the authorized objects of the aerosol device, lock the aerosol device and input the fourth indication information.

[0202] Among them, the fourth indication information is used to prompt that the first object is not an authorized object of the aerosol device.

[0203] In the technical solutions of S207 to S210, when the compliance verification of the first object fails and the first age prediction result reaches the age threshold, the aerosol device requests the terminal device to determine whether to use the first object as an authorized object of the aerosol device, so as to determine whether to activate the heating element or lock the aerosol device after receiving the first response result from the terminal device. In this way, when the compliance verification of the first object fails, by sending the first request information to the terminal device, it can be ensured whether to open the use permission of the aerosol device for the first object, that is, whether to activate the heating element, providing a fault-tolerant processing solution for the identity verification of the users of the aerosol device. Thus, the situation where the aerosol device is directly locked due to the change of the object characteristics of the authorized object of the aerosol device can be reduced, and the user experience can be improved. It is also possible to add an authorized object during the use of the aerosol device, flexibly set the authorized users of the aerosol device, and expand the applicable range of the aerosol device.

[0204] Continuing to combine Figure 3 In the application scenario shown, after waking up the electronic atomizer in S11 and starting the retina scanning module to obtain the biometric information of user U, it enters S12. The electronic atomizer sends the collected biometric information to the client (an example of the terminal device). The client compares the biometric information with the cloud data (that is, the biometric information of the retina images of the real users of the electronic atomizer stored in the cloud, an example of the object feature sample). In S13, the client determines whether the received biometric information is consistent with the cloud data (whether there is an example of an object feature sample that matches the first object feature. S12 is an example of the terminal device verifying the object information of the first object). If it is consistent, it returns an identity verification success message () to the electronic atomizer (an example of the information verification result meeting the compliance verification success condition), and the electronic atomizer activates its heating element. If it is inconsistent, it means that user U is not the real user of the electronic atomizer (that is, the information verification result meets the compliance verification failure condition), enters S14, and then in S16, when it is determined that user U meets the specified age range (an example of the first age prediction result reaching the age threshold), it enters S17. In S17, the electronic atomizer sends a corresponding string instruction (an example of the first request information) to the client. In S18, the client responds to the selection of the real user of the electronic atomizer, determines whether to add the biometric information of user U to the cloud, and returns the selection result (an example of the first response result) to the electronic atomizer. When the real user selects to add the biometric information of user U, the terminal device uploads the biometric information to the cloud for storage. Correspondingly, when the electronic atomizer determines that the selection result is to add the biometric information of user U to the cloud, it activates the heating element. Conversely, the terminal device discards the biometric information, and correspondingly, when the electronic atomizer determines that the selection result is not to add the biometric information of user U to the cloud, it vibrates the vibrator and closes the aerosol device.

[0205] In the embodiment of the present application, when it is detected that the aerosol device is in a state to be heated, the first object feature in the first object image collected will be sent to the terminal device, so that the terminal device verifies the identity of the first object based on the object feature samples respectively corresponding to at least one authorized object stored in advance and the first object feature, and returns the information verification result to the aerosol device, realizing the identity verification of the user of the aerosol device. Only when the information verification result meets the verification success condition, the heating element is started, which can ensure the uniqueness of the aerosol device and improve the user experience. When the aerosol device detects that the information verification result meets the verification failure condition, it performs age assessment on the first object to obtain the first age prediction result, so as to trigger the first indication information when the first age prediction result does not reach the age threshold subsequently, which can limit the age of the user using the aerosol device, realize the safety protection of the aerosol device, and improve the safety of using the aerosol device. When the first age prediction result reaches the age threshold, it requests the terminal device whether to use the first object as an authorized object of the aerosol device, and determines whether to start the heating element or lock the aerosol device after receiving the first response result returned by the terminal device, providing a second identity verification opportunity for the first object, facilitating the user of the aerosol device, and improving the user experience.

[0206] Figure 6 It is a schematic flowchart of another control method of the aerosol device according to the embodiment of the present application. This method can be executed by the aerosol device, and the aerosol device can be Figure 1 the aerosol device 110 in the embodiment shown. This method includes the following steps:

[0207] S401, in response to receiving a feature entry instruction, collect a third object image.

[0208] Among them, the third object image includes the third object feature of the third object. The terminal device communicatively connected to the aerosol device can, in response to the user's instruction to select and enter the object feature, generate a feature entry instruction and send it to the aerosol device. After receiving the feature entry instruction, the aerosol device will control its own image collector to collect the third object image of the third object and extract the third object feature therefrom. The third object feature at least includes the blood vessel distribution pattern of the retina, the thickness of the retinal layer, and the structural features of the optic disc and macula area of the third object.

[0209] In one example, taking the image collector as a near-infrared light camera module, the aerosol device will control the image collector to emit near-infrared light to scan the eyes of the third object. The near-infrared light is reflected back to the image collector after passing through the eyes of the third object. The image collector can process the reflected near-infrared light to generate a retinal image, and perform preprocessing operations such as denoising, enhancement, and alignment on the generated retinal image to obtain the second retinal image of the third object, and this second retinal image is the image of the third object. After obtaining the second retinal image, the image collector will call an image processing algorithm or a deep learning model to extract the features of the third object from the second retinal image. In this way, the aerosol device obtains the features of the third object and the image of the third object.

[0210] S402, perform age assessment on the third object based on the features of the third object to obtain the second age prediction result corresponding to the third object.

[0211] The aerosol device will call an age prediction model to predict the age corresponding to the features of the third object and output the predicted age result, that is, the second age prediction result.

[0212] S403, when it is detected that the second age prediction result reaches the age threshold, send the features of the third object to the terminal device, and the terminal device is used to associate and store the features of the third object with the third object and determine that the third object is an authorized object of the aerosol device.

[0213] When the aerosol device detects that the second age prediction result is greater than or equal to the age threshold, it will send the features of the third object to the terminal device. The terminal device will generate identification information corresponding to the features of the third object, and this identification information is the identification information of the second user, and associate and store the features of the third object with the generated identification information at the storage location where the existing object feature samples are located. In this way, it is determined that the third object is an authorized object of the aerosol device.

[0214] S404, when it is detected that the second age prediction result does not reach the age threshold, send a failure feedback message to the terminal device, and the terminal device is used to output a fourth indication message when receiving the failure feedback message.

[0215] Among them, the failure feedback message is used to prompt that the third object does not meet the device usage conditions, and the fourth indication message is used to prompt to restrict the third object as an authorized object of the aerosol device.

[0216] When the aerosol device detects that the second age prediction result is less than the age threshold, the aerosol device determines that the third object does not meet the device usage conditions, refuses to take the third object as its authorized object, and at this time sends a failure feedback message to the terminal device. In this way, the terminal device will output a fourth indication message, reminding the user that due to age restrictions, the third object feature of the third object cannot be entered, that is, restricting the third object as the authorized object of the aerosol device.

[0217] Continuing to combine Figure 3 With the application scenario shown, when user B (an example of the third object) wants to enter his own retinal biometric information (an example of the third object feature), in S1, the electronic nebulizer detects an external interruption trigger (detecting that a specific button is pressed or a herbal stick is inserted, etc.) and wakes itself up, entering S2. In S2, the electronic nebulizer starts its own retinal detection module (which includes an image collector) and synchronously starts its own Bluetooth module (an example of a communication component), entering S3. In S3, the electronic nebulizer establishes a communication connection with the client through the Bluetooth module. After the client receives the instruction from user B to select retinal entry, in S4, it sends a specified string (an example of a feature entry instruction) to the electronic nebulizer, and the electronic nebulizer starts the retinal scanning module (an example of an image collector) based on this string. In S5, the electronic nebulizer prompts user B to align his eyes (with the retinal scanning module) for scanning. In S6, the electronic nebulizer collects the retinal image of user B through infrared light and starts the image preprocessing module. In S7, the electronic nebulizer uses the image preprocessing module to perform operations such as denoising, enhancement, and alignment on the collected retinal image. In S8, the electronic nebulizer uses an image processing algorithm or a deep learning model to extract the biometric information T (an example of the third object feature) in the processed retinal image (an example of the third object image). The electronic nebulizer will call the age prediction model to evaluate the age corresponding to the biometric information T. When this age is the age of an adult, in S9, the electronic nebulizer will send the extracted biometric information T to the client for storage, and the client will also synchronously upload this biometric information T to the cloud for storage. In S10, the electronic nebulizer closes its own retinal scanning module and exits the retinal entry function, and then enters the sleep mode when needed. To restart the retinal scanning module again when awakened next time (that is, in S11) and enter the subsequent process.

[0218] In the embodiments of the present application, when determining the authorized object of the aerosol device, the object characteristics of the user are collected, and the age of the object is evaluated based on the collected object characteristics. When the age evaluated for the authorized object of the aerosol device reaches the age threshold, the user (i.e., the third object) is determined as an authorized object of the aerosol device; otherwise, the user is rejected as an authorized object of the aerosol device. In this way, the situation where a user who does not meet the device usage conditions operates the aerosol device can be reduced, the safety protection of the aerosol device is achieved, and the safety of using the aerosol device is improved.
