Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of novel tobacco, and particularly relates to an aerosol generating device and a wake-up heating method thereof and a storage medium. BACKGROUND

[0002] In the working process of a novel tobacco heating appliance, the heating temperature needs to be accurately controlled to ensure that the tobacco can produce aerosol that meets the user's needs in the best state. At the same time, in order to provide a good user experience, the user's operation needs to be accurately responded, such as detecting the user's puffing action. This relies on the cooperative work of various sensors, including temperature sensors, airflow sensors, pressure sensors, acceleration sensors, etc. However, these sensors will consume a large amount of electric energy in the continuous working process, which seriously affects the battery endurance of the heating appliance. Especially for some heating appliance products that need to be used for a long time, frequent charging not only brings inconvenience to the user, but also limits the use scenarios and promotion of the product.

[0003] The current heating appliances on the market have many deficiencies in energy consumption control. Most of the sensor systems of the heating appliances lack intelligent control mechanisms, and all the sensors are in full-power operation regardless of whether the user is using it, which undoubtedly causes a lot of energy waste. Some methods that try to control energy consumption, such as simply turning off the sensors or reducing the working frequency of the sensors, often result in poor user experience, and cannot accurately respond to user operations in time, affecting the heating effect and the puffing experience. CN112167718A discloses a heating control method of a heating non-combustion appliance. The method detects the motion parameters of the appliance to determine whether the current action is a target action, and if it is a target action, a pre-heating instruction is triggered and the heating body of the appliance is controlled to heat. This method does not need to turn on the heating switch on the appliance, can automatically trigger the pre-heating instruction, improves the user's experience, and does not trigger the pre-heating instruction when the user's current action is not the target action, reducing energy waste. However, this patent still has the problem of low heating efficiency. CN112205683A proposes a progressive heating circuit for a heating non-combustion appliance. The circuit includes a control unit, a sensor, a power regulation circuit, and a heating sheet. The control unit adjusts the output power of the power regulation circuit according to the sensor information to realize intelligent control of the appliance and save the cartridge and battery power of the appliance. However, this patent still has the problem of imperfect intelligent control.

[0004] Therefore, it has become a key problem to be solved in the field of novel tobacco heating appliances to develop a technical solution that can effectively reduce the energy consumption of the heating appliance while ensuring timely and accurate response to user operations and improving user experience.

[0056] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0057] Please refer to Figure 1 The present application provides an aerosol generating device, which comprises a heating chamber 44, a heating assembly 2, a sensing assembly, a control assembly 4 and a battery assembly 1.

[0058] The heating assembly 2 is used to heat the aerosol forming substrate accommodated in the heating chamber 44 during operation to generate aerosol.

[0059] The battery assembly 1 supplies power to other elements, and the control assembly 4 controls the heating of the heating assembly 2.

[0060] Specifically, the control assembly 4 comprises a central processing unit 41, a memory 42 and a communication module 43, wherein the central processing unit 41 is used to perform data processing and control the heating operation of the heating unit, the memory 42 is used to store control programs and parameter settings, and the communication module 43 is used to interact with various sensing assemblies and external devices.

[0061] The sensing assembly mainly consists of a low-power sensing unit and a high-precision sensing unit, for example, including a temperature sensor 32, an airflow sensor 31, a pressure sensor and an acceleration sensor, etc.

[0062] The low-power sensing unit serves as a first-level trigger sensor, which is used to preliminarily detect the actions that may be related to the user's use of the heated aerosol generating device. The acceleration sensor is set as the low-power sensing unit, which can sensitively detect the action of the user picking up the heated aerosol generating device. In addition, the low-power sensing unit can also be an accelerometer, a gyroscope, etc.

[0063] When the user picks up the heated aerosol-generating device, the acceleration sensor will capture the change in acceleration and transmit this signal to the control component 4 of the aerosol-generating device.

[0064] Among them, the temperature sensor 32 is used to detect the internal temperature of the aerosol-generating device and feedback to the control component 4, the airflow sensor 31 is used to detect the suction airflow and feedback to the control component 4, the pressure sensor is used to detect the suction pressure and feedback to the control component 4, and the acceleration sensor is used to detect the acceleration of the user picking up the aerosol-generating device and feedback to the control component 4.

[0065] The heating assembly 2 includes a heating body and a heating control circuit. The heating body is used to heat the cigarette inside the aerosol-generating device, and the heating control circuit adjusts the heating power according to the control instruction of the control component 4.

[0066] The control component 4 dynamically adjusts the output power of the heating control circuit by detecting the information feedback by each sensing unit, and realizes the intelligent control of the aerosol-generating device.

[0067] The battery assembly 1 is used to provide power support for the aerosol-generating device, and the power consumption of the battery assembly 1 is monitored in real time by the control component 4. When the power is lower than the preset threshold, the control component 4 automatically enters the low-power standby mode.

[0068] The control component 4 also includes an action recognition program. When it is detected that the acceleration of the user picking up the aerosol-generating device exceeds the preset value, the airflow sensor 31 and the pressure sensor are started for suction detection. When the initial suction trigger is detected, the control component 4 completely wakes up all sensing units;

[0069] When a continuous suction behavior is detected, all sensor modules are kept working; when the suction is stopped, the control component 4 enters the low-power standby mode.

[0070] In the standby state, the control component 4 only keeps the basic function modules with the lowest power consumption running, including the acceleration sensor and the microcontroller with the lowest power consumption. Other high-power modules are in standby sleep state. Through this time-sharing and partition activation mechanism, the overall power consumption of the aerosol-generating device is effectively reduced.

[0071] The control component 4 also includes a PWM control circuit, which adjusts the duty cycle of the PWM signal to realize voltage control of the heating sheet, thereby realizing dynamic adjustment of the heating power. The feedback signals of the temperature sensor 32, the airflow sensor 31 and the pressure sensor are connected to the PWM control circuit to form a closed-loop control system to ensure the accuracy and stability of the heating process.

[0072] The aerosol-generating device further comprises a liquid crystal display screen for displaying the screen, which is used to display the current temperature, power state, working mode and other information. Through the liquid crystal display screen, users can intuitively understand the working state of the aerosol-generating device, and realize human-computer interaction.

[0073] The aerosol-generating device further comprises a setting button for users to set personalized parameters such as temperature preset, puffing times, etc. Through the setting button, the working mode of the aerosol-generating device can be flexibly adjusted according to user needs, improving user experience.

[0074] More preferably, in order to further optimize energy consumption control effect, the heating aerosol-generating device is also equipped with an energy consumption monitoring module. This module monitors the energy consumption of the entire heating aerosol-generating device in real time, including the power consumption of the sensor assembly, the heating assembly 2 and other functional modules.

[0075] The energy consumption monitoring module feeds back the collected energy consumption data to the control assembly 4, which dynamically adjusts the wake-up strategy of the sensor assembly and the working mode of the heating system according to these data.

[0076] If it is found that the energy consumption is too high at a certain stage, the control assembly 4 will automatically optimize the working process of the sensor, reduce unnecessary sensor activation times, or adjust the power output of the heating system to reduce overall energy consumption.

[0077] At the same time, the energy consumption monitoring module can also transmit the energy consumption data to the user's mobile device (such as a mobile phone, a mobile computer, etc.) through wireless communication such as Bluetooth, and the user can view the energy consumption of the heating aerosol-generating device through a special application program, understand the impact of their own usage habits on energy consumption, and thus use the heating aerosol-generating device more reasonably.

[0078] Exemplarily, the central processor 41 of the control assembly 4 adopts an STM32F103C8T6 chip with a main frequency of 72MHz, a memory of 256KB Flash and 144KB RAM. The memory 42 adopts an AT24C256 chip with a capacity of 256KB. The communication module 43 adopts a Bluetooth 4.0 chip CC2541, which supports Bluetooth data transmission.

[0079] The central processor 41 performs data processing and controls the heating operation of the heating unit, and the read-write memory 42 stores control programs and parameter settings, and interacts with various sensor assemblies and external devices through the communication module 43.

[0080] The sensor assembly can include a temperature sensor 32, an airflow sensor 31, a pressure sensor and an acceleration sensor. The temperature sensor 32 adopts a PT100 platinum resistance temperature sensor 32 with a measurement range of 0-200℃.

[0081] The air flow sensor 31 adopts a MEMS digital air flow sensor 31LMS311, with a measurement range of 0-5 m / s. The pressure sensor adopts an MPXV5010DG33, with a measurement range of 0-10 kPa.

[0082] The acceleration sensor adopts an ADXL335, with a measurement range of ±3g. These sensors are all connected to the control component 4 through an I2C bus, and real-time detection and feedback of various parameters to the control component 4.

[0083] The heating component 2 includes a heating body and a heating control circuit. The heating body, for example, adopts a ceramic heating element, with a maximum power of 40W. The heating control circuit is composed of a PWM control circuit, which realizes dynamic adjustment of the heating power by adjusting the duty cycle of the PWM signal.

[0084] The control component 4 adjusts the duty cycle of the PWM control circuit based on the temperature information fed back by the temperature sensor 32, to realize accurate control of the heating body.

[0085] The battery component 1 adopts a lithium ion battery, with a capacity of 3000mAh and a voltage of 3.7V. The battery component 1 realizes power monitoring through a power monitoring chip MAX8904, and when the power is lower than 20%, the control component 4 automatically enters a low-power standby mode.

[0086] The aerosol generating device also includes a 2-inch liquid crystal display screen for displaying current temperature, power status, working mode and other information. Through the setting button, temperature preset value, puffing times and other parameters can be set.

[0087] Please refer to Figure 2 The present application provides a wake-up heating method, which can be applied to the above-mentioned aerosol generating device. The wake-up heating method specifically includes:

[0088] Step S1: The control component obtains first sensing data of the low-power sensing unit, and analyzes the first sensing information to obtain a first sensing result.

[0089] Among them, the low-power sensing unit includes an acceleration sensor.

[0090] Specifically, step S1 includes:

[0091] Step S11: The control component obtains acceleration change data of the acceleration sensor.

[0092] Step S12: The control component determines whether the acceleration change data exceeds a first threshold value: if yes, the first sensing result is determined as the user holding the aerosol generating device.

[0093] It can be understood that the acceleration sensor will immediately send a trigger signal to the control component 4 after detecting the user's action of picking up the aerosol generating device.

[0094] In addition, the acceleration sensor can also perceive other interactive actions of the user, such as touch, tilt, etc.

[0095] Since the acceleration sensor has the characteristics of low power consumption, it will not consume too much power even if it continues to work in a long standby state. After receiving the trigger signal of the acceleration sensor, the control component 4 will not immediately wake up all high-precision sensors with high power consumption, but enter a pre-judgment stage.

[0096] The control component 4 will analyze the signal sent by the acceleration sensor according to the preset algorithm to determine whether the action really means that the user is about to perform a puffing operation.

[0097] This pre-judgment process can effectively avoid unnecessary sensing unit wake-up and increased energy consumption caused by false actions (such as the user only briefly picking up the heating smoking set for viewing, etc.).

[0098] Step S2: The control component selectively activates the high-power consumption sensing unit according to the first sensing result.

[0099] Among them, the way to activate the high-power consumption sensing unit can include partial activation, complete activation, or adjusting the power consumption state, not just from off to activation.

[0100] When the control component 4 preliminarily determines that the user is about to perform a puffing operation through the analysis of the acceleration sensor signal, it will further activate the high-precision sensing unit such as the airflow and pressure sensor directly related to the puffing action.

[0101] The airflow sensor 31 is used to detect the change of airflow inside the aerosol generating device, and the pressure sensor can accurately measure the pressure change generated when the user puffs.

[0102] These high-precision sensing units quickly enter a working state after receiving the activation signal of the control unit to accurately detect the user's puffing action.

[0103] Step S3: The control component obtains second sensing information of the high-power consumption sensing unit and analyzes the second sensing information to obtain a second sensing result.

[0104] Among them, the high-power consumption sensing unit includes the airflow sensor 31 and the pressure sensor.

[0105] Specifically, step S3 includes:

[0106] Step S31: The control component obtains the airflow parameter of the airflow sensor.

[0107] Step S32: The control component determines whether the airflow parameter change data exceeds a second threshold value: if yes, the second sensing result is that the airflow of the heating chamber changes.

[0108] Step S33: The control component acquires the pressure parameter of the pressure sensor.

[0109] Step S34: The control component determines whether the pressure change data exceeds a third threshold value: if yes, the second sensing result is the pressure change caused by the user's puffing.

[0110] Step S4: The control component controls the adjustment of the heating-related parameter of the heating component according to the second sensing result.

[0111] The heating-related parameter of the heating component 2 includes heating power, time, etc., and can also include different stages such as preheating and starting heating.

[0112] Specifically, step S4 includes:

[0113] Step S41: The control component determines whether the second sensing result meets the puffing feature: if yes, the heating component is activated for heating.

[0114] It can be understood that only when the airflow sensor 31 detects a significant airflow change and the pressure sensor detects a pressure change meeting the puffing feature, the control component 4 confirms that the user is performing a puffing operation, and completely wakes up the heating system and other related functional modules of the entire aerosol generating device, ensuring that the aerosol generating device can respond to the user's puffing demand in a timely and accurate manner, and providing a good puffing experience for the user.

[0115] Please refer to Figure 3 and Figure 4 During the working process of the aerosol generating device, the activation work can be performed according to the following steps:

[0116] S1, initialize system configuration, set various parameters;

[0117] S2, detect the motion state of the smoking set, detect the acceleration of the user picking up the smoking set through the acceleration sensor;

[0118] S3, if the acceleration is greater than 1.5g, start the airflow sensor 31 and the pressure sensor for puffing detection;

[0119] S4, if the airflow is greater than 0.5m / s and the pressure is greater than 100Pa, it is determined as initial puffing trigger, and S5 is executed;

[0120] S5, completely wake up all sensing unit modules, and start the heating unit to heat;

[0121] S6, if the airflow is greater than 1.0 m / s, keep all sensor modules working, perform S7;

[0122] S7, monitor the temperature of the heating body in real time through the temperature sensor 32 until the preset temperature is reached;

[0123] S8, if the airflow is less than 0.2 m / s, determine that the puffing is stopped, perform S9;

[0124] S9, enter a low-power standby mode.

[0125] Among them, the sensing assembly can be divided into a high-power consumption sensing unit and a low-power consumption sensing unit, and the power consumption ratio of the high-power consumption sensing unit to the low-power consumption sensing unit is greater than or equal to 2. That is, compared with the prior art, the high-power consumption sensing unit is gradually awakened from the low-power consumption sensing unit for data collection through the hierarchical awakening mode, which effectively saves the power of the aerosol generating device and improves its portability.

[0126] According to different working stages and user operations, the sensing units are activated in time and in different areas.

[0127] In the standby state, only the low-power consumption acceleration sensor is in the working state, and other high-precision sensing units are in the sleep state, so as to reduce the power consumption to the greatest extent.

[0128] When the acceleration sensor detects the user's action of picking up the aerosol generating device and triggers the control unit, the pre-activation stage is entered, at this time only part of the sensing units related to the preliminary judgment of the user's intention (such as part of the detection function of the airflow sensor 31) are activated, and preliminary detection and judgment are performed.

[0129] Once the user's puffing action is confirmed, all sensing units and function modules related to heating and puffing are fully activated to achieve accurate response to user operation. During the puffing process, the working state of the sensing unit is dynamically adjusted according to the interval time and frequency of the user's puffing.

[0130] If the user continues to puff in a short time, part of the sensing units remain in the working state to respond quickly; if the user puffs at a long interval, in addition to the necessary monitoring sensing units, other sensing units can enter a low-power mode or a sleep state, and be reactivated when the next puffing action is triggered.

[0131] The time and area activation control strategy can include:

[0132] T1, standby state: only the acceleration sensor and the microcontroller work, and the power supply current is less than 50 μA;

[0133] T2, initial puff detection state: airflow sensor 31 and pressure sensor work, power supply current 100 mA;

[0134] T3, heating preparation state: temperature sensor 32 and acceleration sensor work, power supply current 200 mA;

[0135] T4, heating process state: all sensor modules work, power supply current 300 mA;

[0136] T5, puff feedback state: airflow sensor 31 and pressure sensor work, power supply current 150 mA.

[0137] Exemplarily, when the acceleration sensor detects that the acceleration of the user picking up the aerosol generating device exceeds 1.5g, the airflow sensor 31 and the pressure sensor are started for puff detection.

[0138] If the airflow is greater than 0.5 m / s and the pressure is greater than 100 Pa, it is determined that the initial puff trigger is triggered, and the control unit fully wakes up all sensor modules.

[0139] If the airflow continues to be greater than 1.0 m / s, all sensor modules remain working; if the airflow is less than 0.2 m / s, it is determined that the puff is stopped, and the control unit enters a low-power standby mode.

[0140] In the standby state, the control assembly 4 only keeps the acceleration sensor and the microcontroller working, and the microcontroller keeps time synchronization through the internal oscillator. Other modules are in standby sleep state, and the power supply current is less than 50 μA.

[0141] It can be understood that the present application adopts a low-power sensor (such as an acceleration sensor) as a first-level trigger, and a high-precision sensor (such as the airflow sensor 31 and the pressure sensor) for confirming the user's puffing action, to form a layered wake-up sensor system architecture, including the selection of sensors, the installation position, and the connection relationship and signal transmission logic between them.

[0142] Moreover, according to the user operation and the working stage of the heating smoking set, the sensor can be activated in time and in different zones, including only the low-power sensor working in the standby state, part of the sensor functions being activated in the pre-judgment stage, being fully activated after confirming the puffing, and the specific implementation mode and control logic of dynamically adjusting the working state of the sensor according to the interval time and frequency in the puffing process.
