[0003] Currently, electronic vaping devices activate and control based on the sensing results of a microphone installed in the airway structure. The air pressure sensing element inside the microphone deforms in response to the user's puffing action, generating a high voltage level. The electronic vaping device's processor then triggers the switching circuit to enter the conductive state based on this high voltage level. However, in actual use, the microphone's air pressure sensing element is easily deformed by other accidental factors other than the user's puffing action. This can lead to a certain probability of false activation of the electronic vaping device, posing a certain safety hazard.

[0020] Figure 1 This is a structural diagram of an electronic atomization device provided in an embodiment of the present application, which includes: a holding behavior detection sensor 101, a puffing behavior detection sensor 102, a switch circuit 103, a memory 104 and a processor 105, wherein the holding behavior detection sensor 101 is used to detect first sensor data for the holding portion of the electronic atomization device; the puffing behavior detection sensor 102 is used to detect second sensor data for the puffing portion of the electronic atomization device; the switch circuit 103 is used to execute a circuit conduction instruction sent by the processor to enable the electronic atomization device to enter an enabled state; the processor 105 is used to Executing the computer program stored in the memory 104, when the processor 105 executes the computer program, it is specifically used to: identify the relative state of the holding part according to the first sensor data detected by the holding behavior detection sensor; if the relative state of the holding part is the held state, send a start signal to the puffing behavior detection sensor to instruct the puffing behavior detection sensor to enter the working state; based on the second sensor data detected by the puffing behavior detection sensor, determine whether a valid puff event is satisfied; if a valid puff event is satisfied, send a circuit conduction instruction to the switch circuit of the electronic atomization device to control the electronic atomization device to enter the enabled state.

[0021] The holding behavior detection sensor of this embodiment is arranged on the holding part of the electronic atomization device. In an optional embodiment, the holding behavior detection sensor can be an infrared sensor. When the user's palm / fingers touch the holding part, the infrared light signal emitted by the sensor is reflected, and the sensor identifies the user's holding behavior based on the reflected infrared light signal.

[0022] The puffing behavior detection sensor of this embodiment is disposed in the puffing portion of the electronic atomization device. In an optional embodiment, the puffing behavior detection sensor may include a PPG (Photo Plethysmo Graphy) sensor and / or a TOF (Time of Flight) sensor. Furthermore, the TOF sensor may be a dTOR or iTOF sensor. The PPG sensor can detect PPG signals with subcutaneous blood flow characteristics in the user's mouth, thereby determining the user's puffing action, while the TOF sensor can detect the TOF signal to identify the proximity of the user's mouth to the puffing portion of the electronic atomization device, thereby determining the user's impending puffing behavior.

[0023] The switching circuit of this embodiment is used to control the start and stop of the electronic atomization device. The switching circuit can control the voltage input at the RF source DC-DC through the PIN port of the MCU with different costs and response speeds. When the switching circuit is turned on, the electronic atomization device enters the enabled state and each circuit module enters the working state.

[0024] It should be noted that the memory can be a high-speed random access memory (RAM) or a non-volatile memory, such as a disk drive. The memory is used to store computer programs (i.e., executable program code), and the processor is coupled to the memory.

[0025] In addition, an embodiment of the present application further provides a computer-readable storage medium, which can be provided in the aforementioned electronic atomization device. Figure 1 Memory in the illustrated embodiment.

[0026] The computer-readable storage medium stores a computer program, which, when executed by a processor, can implement the process of the startup control method of the aforementioned electronic atomization device. Furthermore, the computer-readable storage medium can also be a USB flash drive, a mobile hard disk, a read-only memory (ROM), a RAM, a magnetic disk, or an optical disk, etc., which can store program code.

[0027] In order to solve the problem that the electronic atomizing device provided by the related art uses a microphone induction method for startup control, which has a certain probability of false startup, an embodiment of the present application provides a startup control method for an electronic atomizing device, wherein the gripping part of the electronic atomizing device is equipped with a gripping behavior detection sensor and the suction part is equipped with a suction behavior detection sensor. Figure 2 This is a basic flow chart of a startup control method for an electronic atomization device provided in one embodiment of the present application, specifically including the following steps:

[0028] Step 201: Identify the relative state of the gripping part according to first sensor data detected by a gripping behavior detection sensor.

[0029] Specifically, in actual applications, when a user uses an electronic atomizing device, the first action performed is to pick up the electronic atomizing device in a placed state. For the user's standard usage behavior, a specific part of the electronic atomizing device is usually held. This embodiment defines the part that the user usually holds when inhaling the electronic atomizing device as the holding part.

[0030] It is worth mentioning that the holding behavior detection sensor of this embodiment may include an infrared sensor, a capacitive sensor, a pressure sensor, etc., and it only needs to ensure that it can sense the user's behavior of holding the electronic atomization device.

[0031] In an optional implementation of the present embodiment, the above-mentioned holding behavior detection sensor is an infrared sensor, and the above-mentioned identification of the relative state of the holding part based on the first sensor data detected by the holding behavior detection sensor includes: comparing the infrared light radiation data per unit area detected by the infrared sensor with a preset infrared light radiation threshold; identifying the relative state of the holding part based on the comparison result; wherein, if the infrared light radiation data is greater than or equal to the infrared light radiation threshold, the relative state of the holding part is a held state.

[0032] Specifically, capacitance detection and pressure detection have large accidental errors in complex and changeable application scenarios. Therefore, this embodiment adopts infrared method to detect holding behavior, that is, controlling the infrared sensor to emit infrared light outward. When the user's fingers or palms hold the electronic atomization device, the infrared light is reflected and received by the infrared sensor. Next, the infrared light radiation data collected by the infrared sensor is analyzed to identify whether the infrared light radiation data per unit area is greater than or equal to a preset threshold. If so, it is determined that the holding part of the electronic atomization device is in a state of being held by the user's fingers or palm. Based on this, the accuracy of the holding behavior detection results can be effectively improved.

[0033] Step 202: If the relative state of the gripping portion is the gripped state, a start signal is sent to the puffing behavior detection sensor to instruct the puffing behavior detection sensor to enter a working state.

[0034] Specifically, in addition to the sensor provided on the holding part of the electronic atomization device, this embodiment also provides a sensor on the suction part (i.e., the nozzle), which implements the detection of the suction behavior. It should be understood that the suction behavior detection sensor can be a single sensor or can include multiple sensors, and the sensor type can be an airflow sensor, a PPG sensor, a TOF sensor, etc. It is worth mentioning that this embodiment further triggers the suction behavior detection sensor to enter the working state after determining that the user is effectively holding the electronic atomization device, which can reduce power consumption. In addition, the holding behavior detection of this embodiment is only the first detection stage of the startup control process, which has higher control accuracy than the startup control based on a single detection result.

[0035] Step 203: Determine whether a valid puff event is satisfied based on the second sensor data detected by the puff behavior detection sensor.

[0036] Illustratively, the puffing behavior detection sensor of this embodiment includes a PPG sensor, and accordingly, identifies a first waveform feature of the photoplethysmographic data detected by the PPG sensor; matches the first waveform feature with a second waveform feature, wherein the second waveform feature is a waveform feature of the photoplethysmographic data corresponding to the subcutaneous blood flow state of the mouth; and determines whether a valid puffing event is satisfied based on the matching result, wherein if the matching degree between the first waveform feature and the second waveform feature is greater than or equal to a preset matching degree threshold, a valid puffing event is satisfied.

[0037] Specifically, photoplethysmography data has a stronger specificity than conventional data (such as airflow, air pressure, temperature, etc.), which can effectively eliminate accidental errors. Based on this, this embodiment sets a PPG sensor on the outside of the suction part. In actual application, if the user needs to inhale the electronic atomization device, the PPG signal detected by the PPG sensor will have the characteristics of subcutaneous blood flow in the human mouth, such as Figure 3 Figure 1 shows a schematic diagram of a PPG signal provided by this embodiment. The peak points in the figure represent the peak reflection values ​​generated by subcutaneous blood flow. Thus, when this embodiment identifies PPG signal characteristics that include subcutaneous blood flow characteristics at the mouth, it confirms that a valid puffing event has occurred. It should be noted that this embodiment processes photoplethysmography data using methods including, but not limited to, bandpass filtering, high-pass filtering, and periodic segmentation. When analyzing the signal within a single period, feature types include, but are not limited to, singularity, slope, area, and slope.

[0038] In an optional implementation of this embodiment, the puffing behavior detection sensor further includes a time-of-flight (TOF) sensor. Accordingly, sending a start signal to the puffing behavior detection sensor includes sending a start signal to the TOF sensor. Accordingly, before identifying the first waveform feature of the photoplethysmography data detected by the PPG sensor, the method further includes comparing the relative distance data detected by the TOF sensor with a preset distance threshold; if the relative distance data is less than or equal to the distance threshold, sending a start signal to the PPG sensor to instruct it to enter an operational state.

[0039] Specifically, in actual application scenarios, a complete and effective puffing behavior of an electronic atomizing device requires a mouth approaching action before the puffing action. Based on this, this embodiment also configures a TOF sensor in the puffing part of the electronic atomizing device. When the user's mouth approaches the puffing part of the electronic atomizing device, the TOF sensor can detect the mouth reflection signal, thereby obtaining a relative distance data. When the distance is less than or equal to the preset distance threshold (for example, 1 to 2 cm), it indicates that the user's mouth is effectively close to the electronic atomizing device, thereby controlling the PPG sensor to start.

[0040] In an optional implementation of the present embodiment, the above-mentioned judgment of whether a valid puffing event is satisfied based on the second sensor data detected by the puffing behavior detection sensor includes: matching the typical data features of the second sensor data detected by the puffing behavior detection sensor with preset universal data features, wherein the universal data features are puffing behavior data features that conform to the habitual puffing behaviors of all users; if the match succeeds, extracting the first global data feature corresponding to the first sensor data, and extracting the second global data feature corresponding to the second sensor data detected by the puffing behavior detection sensor; matching the first data feature and the second data feature with corresponding legal data features, respectively, wherein the legal data features are usage behavior data features corresponding to the habitual usage behaviors of legal users of the electronic atomization device; and judging whether a valid puffing event is satisfied based on the matching results.

[0041] Specifically, in the related art, it is usually determined that a valid puffing event is satisfied only when the puffing behavior is identified. However, in actual applications, the electronic atomization device may be used by users other than the legitimate user (such as the owner of the electronic atomization device), and the owners of some electronic atomization devices have exclusive use requirements. Therefore, after determining that a general puffing event is satisfied based on the typical data features of the data detected by the puffing behavior detection sensor, this embodiment further extracts the global data features of the data detected by the holding behavior sensor and the data detected by the puffing behavior detection sensor, and matches the global data features of the two with the corresponding usage behavior data features of the corresponding legitimate users, and finally determines whether the current puffing event satisfies the valid puffing event of the legitimate user based on the matching results. Therefore, this embodiment can allow the electronic atomization device to start only when the legitimate user puffs on the electronic atomization device, thereby satisfying the exclusive use requirements of the legitimate user.

[0042] In an optional implementation of this embodiment, the above-mentioned determination of whether a valid puff event is satisfied based on the matching result includes: obtaining a first calculation weight and a first matching degree corresponding to the first global data feature, and obtaining a second calculation weight and a second matching degree corresponding to the second global data feature, wherein the first calculation weight is less than the second calculation weight; performing a weighted calculation based on the first calculation weight and the first matching degree, the second calculation weight, and the second matching degree to obtain an overall matching degree; and determining whether a valid puff event is satisfied based on the overall matching degree.

[0043] Specifically, in actual applications, the differences in the holding behaviors of different users for electronic atomization devices are relatively small and relatively more random, while the differences in the puffing behaviors are relatively large and relatively less random. Therefore, this embodiment assigns different calculation weights to the first global data feature and the second global data feature, and assigns a larger calculation weight to the second global data feature, so as to perform weighted calculation (such as weighted sum calculation or weighted average calculation) on the matching degree after matching the first global data feature and the second global data feature with the corresponding legal data feature respectively. Finally, the calculated overall matching degree is compared with the preset matching degree threshold to determine whether a valid puffing event is satisfied. When the overall matching degree is greater than or equal to the matching degree threshold, a valid puffing event is satisfied. Thus, the accuracy of the determination of the valid puffing event can be improved.

[0044] Step 204: If a valid puff event is satisfied, a circuit conduction instruction is sent to a switch circuit of the electronic atomization device to control the electronic atomization device to enter an enabled state.

[0045] Specifically, upon confirming a valid puff event, this embodiment sends a circuit-on instruction to the switch circuit module to control the switch circuit module to conduct, putting the relevant circuit modules of the electronic atomization device into operation. Because this embodiment integrates multimodal user behavior detection results to control the startup of the electronic atomization device, it can avoid accidental misstarts, improve the startup accuracy of the electronic atomization device, and ensure the safety of the electronic atomization device.

[0046] In an optional implementation of this embodiment, before sending the circuit-on instruction to the switch circuit of the electronic atomization device, the method further includes: identifying cardiopulmonary function assessment data of a user of the electronic atomization device based on the first waveform characteristics; and determining a corresponding target output power based on the cardiopulmonary function assessment data. Accordingly, sending the circuit-on instruction to the switch circuit of the electronic atomization device includes: sending the circuit-on instruction carrying the target output power to the switch circuit of the electronic atomization device.

[0047] Specifically, in related technologies, electronic atomization devices typically heat at a fixed output power after startup. Therefore, the amount of aerosol inhaled per unit time is consistent for different users. However, different users have different cardiopulmonary functions, and their preferences for aerosol inhalation volume vary. Therefore, a fixed output power makes it difficult to accommodate the aerosol inhalation needs of different users. Based on this, this embodiment further assesses the user's cardiopulmonary function based on data detected by the PPG sensor and adaptively determines the target output power. Furthermore, after detecting a valid puff event, the electronic atomization device is controlled to enter a startup state, and then the heater is controlled to heat according to the target output power to provide the user with an aerosol volume that matches their cardiopulmonary function level.

[0048] Figure 4 The method in this application is a detailed method for controlling the startup of an electronic atomization device, which specifically includes the following steps:

[0049] Step 401: Identify the relative state of the gripping portion based on infrared radiation data per unit area detected by an infrared sensor provided on the gripping portion;

[0050] Step 402: If the relative state of the gripping portion is the gripping state, a start signal is sent to the TOF sensor provided in the suction portion to instruct the TOF sensor to enter a working state;

[0051] Step 403: Calculate corresponding relative distance data based on the TOF signal detected by the TOF sensor;

[0052] Step 404: If the relative distance data is less than or equal to the preset distance threshold, a start signal is sent to the PPG sensor provided in the suction unit to instruct the PPG sensor to enter a working state;

[0053] Step 405: Match the first waveform feature of the photoplethysmography data detected by the PPG sensor with the second waveform feature of the photoplethysmography data corresponding to the subcutaneous blood flow state of the mouth;

[0054] Step 406: If the match succeeds, then corresponding cardiopulmonary function assessment data is determined based on the first waveform feature;

[0055] Step 407: determining the corresponding target output power according to the cardiopulmonary function assessment data;

[0056] Step 408: Send a circuit conduction instruction carrying the target output power to the switch circuit of the electronic atomization device, so that the electronic atomization device enters an enabled state and controls the heater to heat according to the target output power.

[0057] Based on the above technical solution, on the one hand, the multimodal sensor can identify different user behaviors in stages, providing an effective reference for the accurate startup of the electronic atomizing device; on the other hand, the user's cardiopulmonary function level can be identified according to the detection data of the PPG sensor, and the output power of the electronic atomizing device can be controlled accordingly, thereby effectively matching the user's personalized aerosol inhalation needs.
