However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0041] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0042] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0043] Each time an aerosol device using HNB technology atomizes an aerosol matrix, it will go through four stages (these four stages are also called a heating cycle), namely the preheating stage, the main heating stage, the steady-state holding stage and the cooling stage. In the preheating stage, the aerosol device will control the temperature of its own heating element to heat the aerosol matrix from room temperature to a certain temperature within a certain period of time, for example, 100 degrees Celsius (℃) or 150℃, etc. In the main heating stage, the aerosol device will continue to control the temperature of the heating element to further heat the aerosol matrix to a higher temperature, for example, 350℃ or 300℃, etc. In the steady-state holding stage, the aerosol device will continue to control the element temperature of the heating element using a proportional-integral-differential (PID) control algorithm to stabilize the temperature of the aerosol matrix within a certain temperature range for a period of time, for example, 300±5℃. During the cooling stage, when the user completes the use of the aerosol device, the aerosol device will activate its own heat dissipation device to quickly cool the heating element to room temperature, thereby reducing the temperature of the aerosol matrix.

[0044] In the above four stages, except for the cooling stage, in each of the other stages, the aerosol device will control the element temperature of the heating element based on its own pre-stored fixed temperature change curve. When controlling the element temperature of the heating element, the aerosol device will calculate the real-time temperature of the heating element based on the actual resistance value of the heating element, the initial resistance value corresponding to the heating element in the initial parameters of the aerosol device, and the initial ambient temperature to determine whether the heating element is heated to a specific temperature. However, during the use of the aerosol device, the resistance value of the heating element may increase due to oxidation and other factors, resulting in a difference between the resistance value of the heating element and the initial resistance value when the heating element does not work. There may also be a difference between the ambient temperature of the aerosol device and the initial ambient temperature. These differences will cause the energy released during the actual heating process of the heating element to not match the standard, and then cause the heat absorbed by the aerosol matrix to not match the standard, which will seriously affect the atomization effect of the aerosol device and the user experience.

[0045] In addition, during the preheating phase of each heating cycle, due to the fixed temperature change curve, the aerosol device will basically control the heating element to heat up to a specific temperature under the same heating time. Due to the basically same specific temperature and heating time, the energy emitted by the heating element is basically the same, but the energy that can be absorbed by the aerosol matrix of different humidity for atomization is different, which will affect the atomization effect of the aerosol device. In addition, the solidification of the initial parameters of the aerosol device will further affect the atomization effect of the aerosol device, thereby seriously affecting the user experience.

[0046] Combine the following Figure 1 The temperature rise curves of aerosol matrices with different humidity shown in FIG. 1 illustrate the principle that aerosol matrices with different humidity affect the user's usage experience. Figure 1 In the figure, T0 is the temperature rise curve of the aerosol matrix with moderate humidity in the preheating stage, T2 is the temperature rise curve of the aerosol matrix with too high humidity (i.e., too wet aerosol matrix) in the preheating stage, and T1 is the temperature rise curve of the aerosol matrix with too low humidity (i.e., too dry aerosol matrix) in the preheating stage. Figure 1 Tmax in the figure represents the target temperature in the preheating stage.

[0047] pass Figure 1 It can be seen that at the time 0 to ty, the energy absorbed by the aerosol matrix with moderate humidity can be as follows: Figure 1 The area of ​​the pattern enclosed by the T0 curve and the coordinate axis at time ty is shown. The energy absorbed by the overly wet aerosol matrix will be used to evaporate the excess water vapor in it first, and the energy absorbed by the aerosol matrix for heating itself will become smaller. The energy absorbed by the overly dry aerosol matrix is ​​basically used to heat itself, and the energy absorbed by it for heating itself will become larger. Figure 1 It can be clearly seen that at time ty, the area of ​​the pattern enclosed by the T2 curve and the coordinate axis is smaller than the area of ​​the pattern enclosed by the T0 curve and the coordinate axis, and the area of ​​the pattern enclosed by the T1 curve and the coordinate axis is larger than the area of ​​the pattern enclosed by the T0 curve and the coordinate axis.

[0048] The above situation will result in that an overly wet aerosol matrix will heat up slowly during the preheating stage due to less energy absorbed, which will lead to problems such as small aerosol volume and stickiness in the subsequent stage. An overly dry aerosol matrix will heat up rapidly in a short period of time during the preheating stage due to more energy absorbed, which will lead to problems such as large aerosol volume and burning in the subsequent stage. In this case, if the initial parameters of the aerosol device are also inaccurate, the heat that the aerosol matrix can absorb for heating itself will become more unstable, which will seriously affect the user experience.

[0049] However, the aerosol matrix of the aerosol equipment using HNB technology is often packaged in a package box, and the manufacturer usually does not package each aerosol matrix in the package box separately for cost and environmental protection reasons. After opening the package box, the user usually does not use all the aerosol matrix in a short period of time. The remaining aerosol matrix in the package box after opening is often affected by the humidity of the environment. The current aerosol equipment does not have the function of calibrating its own initial parameters and detecting the humidity of the aerosol matrix during the heating process. The initial parameters often fail and the aerosol equipment is too wet or too dry, which will affect the atomization effect of the aerosol equipment and seriously affect the user experience.

[0050] In response to the above problem, an embodiment of the present application provides a control system for an aerosol device, wherein the aerosol device collects its own component parameters during operation, and sends its own component parameters and initial parameters to a terminal device. In this way, the state adjustment result of the aerosol device can be parsed based on the component parameters and initial parameters through the reliable computing power of the terminal device to adjust the operation of the aerosol device, thereby achieving the purpose of timely adjusting the operation of the aerosol device based on the component parameters of the aerosol device that reflect the current heating condition of the heating element during the operation of the aerosol device, which can ensure the atomization effect of the aerosol device, thereby improving the user's experience of using the aerosol device. The aerosol device can detect parameter adjustment instructions in real time, and when the parameter adjustment instruction is detected, it can adjust the value of the initial parameter in time based on the difference between the obtained component parameters and the initial parameters, so as to accurately determine the total energy value related to humidity based on the adjusted initial parameters and send it to the terminal device. The terminal device can determine the current humidity of the aerosol matrix based on the total energy value, and determine whether to extend or reduce the heating time of the heating element based on the current humidity. This not only realizes the adjustment of the initial parameters of the aerosol device, but also can timely perform personalized heating on aerosol matrices with different humidity, thereby improving the atomization effect of the aerosol device and thus improving the user experience.

[0051] The control system of the aerosol device in the embodiment of the present application is introduced below through specific examples.

[0055] The terminal device may be a mobile terminal such as a mobile phone, a tablet computer, a wearable device or a personal digital assistant (PDA). The embodiment of the present application does not impose any restriction on the specific type of the terminal device.

[0056] Continue to combine Figure 2 , the aerosol device 110 also includes a accommodating chamber, which is used to accommodate the aerosol matrix, and the accommodating chamber is provided with an opening so that the aerosol matrix can be inserted into the accommodating chamber. It should be noted that in the aerosol device, the heating element 111 can be configured at the bottom opposite to the opening of the accommodating chamber, or can be arranged in a ring around the cavity wall of the accommodating chamber so as to heat the aerosol matrix. The heating element 111 can be a rod-shaped, sheet-shaped, filament-shaped or film-shaped heating element. The embodiment of the present application does not specifically limit the specific structural type of the heating element. The material of the heating element 111 can be a metal (for example, a nickel-chromium alloy, a titanium alloy or a platinum film, etc.), a ceramic (for example, an alumina ceramic or a silicon carbide ceramic, etc.) or a composite material (for example, a metal-ceramic composite material or a carbon fiber composite material), etc. The embodiment of the present application does not specifically limit the specific material type of the heating element.

[0057] The aerosol device 110 further includes a battery and a circuit substrate, wherein the battery is used to power the aerosol device, and the circuit substrate is used to provide mechanical support and fixation and electrical connection services for electronic components in the aerosol device 110. The aerosol device 110 further includes a first resistor and a second resistor, wherein the first resistor is used to detect the temperature of the battery, and the second resistor is used to detect the temperature of the circuit substrate.

[0060] The aerosol device 110 further includes a proportional-integral-derivative (PID) temperature control component for controlling the element temperature of the heating element to be stable at a target temperature to heat the aerosol substrate.

[0061] The following describes the specific working processes of the aerosol device and the terminal device in the control system of the aerosol device in the embodiment of the present application through specific embodiments.

[0062] Figure 3 is a flowchart of a control system of an aerosol device provided in an embodiment of the present application, such as Figure 3 The workflow shown includes the following steps:

[0063] S101, when the aerosol device is in operation, the component parameters of the aerosol device are collected.

[0064] The control system includes an aerosol device and a terminal device, and the aerosol device includes a heating element.

[0065] The aerosol device stores initial parameters, which represent the temperature rise of the heating element under preset conditions. The preset conditions include that the heating element is not aged and operates normally at 25 degrees Celsius (℃). The initial parameters may include a first reference resistance value and a first reference ambient temperature corresponding to the heating element. The first reference resistance value and the first reference ambient temperature may determine the temperature rise rate and the upper limit of the temperature rise of the heating element under preset conditions. Therefore, the initial parameters may represent the temperature rise of the heating element under preset conditions.

[0066] The component parameters represent the current temperature rise of the heating element. The component parameters may include the second element resistance of the heating element, the first battery temperature corresponding to the first resistor, and the first substrate temperature corresponding to the second resistor at the current ambient temperature. The current ambient temperature is the temperature of the environment in which the aerosol device is located. Generally speaking, factors such as the current ambient temperature and the use time of the aerosol device will affect the initial resistance of the heating element when it is not heated up, that is, the second element resistance. The first battery temperature and the first substrate temperature can reflect the real temperature of the environment in which the aerosol device is located. When the second element resistance differs too much from the first reference resistance, the heating element will heat up slowly (the second element resistance is greater than the first reference resistance, and there is a risk of open circuit) or heat up quickly (the second element resistance is less than the first reference resistance, and there is a risk of short circuit). When the current ambient temperature differs greatly from the first reference ambient temperature, it will affect the heat loss rate of the heating element when it is heated up, thereby affecting the heating element The heating rate, therefore, the component parameters can represent the current heating condition of the heating element.

[0067] During each operation of the aerosol device, component parameters under the current environment can be obtained before the heating element heats up.

[0068] S102, the aerosol device sends component parameters and initial parameters to the terminal device.

[0069] The aerosol device can send component parameters and initial parameters to the terminal device through its own communication component.

[0070] S103, the terminal device receives component parameters and initial parameters.

[0071] The terminal device can receive the component parameters sent by the aerosol device through its own communication component, and the initial parameters are sent to the terminal device.

[0072] S104: The terminal device determines a state adjustment result of the aerosol device based on the component parameters and the initial parameters.

[0073] Among them, the state adjustment result is used to indicate whether the terminal device adjusts the operation status of the aerosol device.

[0074] In one implementation, the state adjustment result includes at least one of an adjustment method of an initial parameter, a first adjustment strategy of a heating parameter of a heating element, or a second adjustment strategy of a storage method of an aerosol substrate of an aerosol device.

[0075] The first adjustment strategy includes a first control instruction for instructing the aerosol device to extend the heating time of the heating element, a second control instruction for instructing the aerosol device to reduce the heating time of the heating element, a third control instruction for instructing the aerosol device to increase the heating power of the heating element, or a fourth control instruction for instructing the aerosol device to reduce the heating power of the heating element. The heating parameters may include the heating time, heating power, or heating temperature of the heating element.

[0076] The second adjustment strategy includes drying or wetting the aerosol substrate of the aerosol device.

[0077] In one implementation, Figure 4 The flowchart of the control system of another aerosol device in the embodiment of the present application is shown, and the workflow includes the following steps:

[0078] The heating element is used to heat the aerosol matrix in the aerosol device, and the state adjustment result includes adjusting the initial parameters;

[0079] S201, the terminal device sends a first adjustment instruction instructing initial parameter adjustment to the aerosol device.

[0080] The heating element is used to heat the aerosol matrix in the aerosol device, and the state adjustment result includes adjusting the initial parameters.

[0081] The first adjustment instruction includes an instruction for instructing the aerosol device to adjust the value of the first reference resistance to the value of the second element resistance, and or an instruction for adjusting the value of the first reference ambient temperature to the smaller value of the first battery temperature and the first substrate temperature.

[0082] The total energy value represents the amount of heat absorbed when the aerosol matrix is ​​heated to the target temperature.

[0083] Before controlling the heating element to heat the first aerosol device, the aerosol device sends the collected component parameters to the terminal device. When the terminal device determines that the initial parameters need to be adjusted based on the component parameters and the initial parameters, the terminal device sends a first adjustment instruction to the aerosol device.

[0084] S202: The aerosol device receives a first adjustment instruction.

[0085] S203: The aerosol device adjusts the initial parameters based on the first adjustment instruction to obtain the first parameters.

[0086] During the operation of the aerosol device, if the first adjustment instruction sent by the terminal device is received, it will detect whether the element temperature of the heating element is the current ambient temperature. If it is the current ambient temperature, the initial parameter is adjusted based on the first adjustment instruction to obtain the first parameter. In this way, the aerosol device can control the heating element to heat the aerosol matrix based on the first parameter. If the aerosol device determines that the element temperature of the heating element is higher than the current ambient temperature, the heating element will be cooled. When the element temperature of the heating element is cooled to the current ambient temperature, the initial parameter is adjusted based on the first adjustment instruction to obtain the first parameter, and the heating element is re-controlled to heat up based on the first parameter (that is, the aerosol matrix is ​​reheated).

[0087] S204: The aerosol device controls the heating element to heat the aerosol matrix based on the first parameter, and obtains a total energy value of the aerosol matrix during the period when the heating element heats the aerosol matrix.

[0088] After obtaining the first parameter, the aerosol device controls the heating element to heat up based on the second reference resistance value corresponding to the heating element in the first parameter and the second reference ambient temperature, so as to heat the aerosol matrix. During the period when the heating element heats the aerosol matrix, the element temperature of the heating element is detected based on the first parameter and the first preset time interval, and the element temperature is used as the temperature of the aerosol matrix. When the aerosol device detects that the aerosol matrix is ​​heated to the target temperature, the aerosol device integrates the collected element temperature of the heating element, and uses the integration result as the total heat absorbed by the aerosol matrix when it is heated from the ambient temperature to the target temperature, that is, the total energy value.

[0089] The following is an explanation of the principle of obtaining the total energy value of the aerosol matrix by the aerosol device. Figure 1It can be seen that the heat absorbed by the aerosol matrix is ​​positively correlated with the element temperature of the heating element and the heating time. During the preheating stage (that is, the period when the aerosol matrix is ​​heated to the target temperature), the total heat absorbed by the aerosol matrix, that is, the total energy value P, can be regarded as the area of ​​the figure enclosed by the element temperature curve of the heating element and the time (t) axis. The area can be integrated, so the aerosol device can use the integral result of the element temperature of the heating element as the total energy value.

[0090] In the embodiment of the present application, the target temperature is the temperature that the heating element needs to reach during the preheating stage of the aerosol device. For example, the target temperature can be between 100 and 250°C. The specific value can be set based on the model of the aerosol device. The embodiment of the present application does not make any specific restrictions. The first preset time interval can be 100 milliseconds (ms), 50ms, or 150ms, etc., which is not specifically limited in the embodiment of the present application.

[0091] In one implementation, the aerosol device determines that the aerosol substrate is heated to the target temperature when detecting that the element temperature of the heating element reaches the target temperature.

[0092] In one implementation, when the aerosol device detects that the element temperature of the heating element continues to rise, and the element temperature is within the preset temperature range within the preset time period, it can be determined that the element temperature of the heating element has reached the target temperature, the preset temperature range includes the target temperature, and the preset time period is less than the total heating time of the preset heating stage. The preset time period can be 2s or 3s, etc., and its specific value can be set by itself. For example, taking the target temperature of 150°C as an example, the aerosol device detects that the element temperature rises from 27°C to 150°C, and the element temperature is between 148°C and 152°C within 0.5s, the aerosol device can determine that the heating element has reached 150°C. In the above technical solution, by detecting the element temperature of the heating element, it is possible to quickly determine whether the aerosol matrix has reached the target temperature, thereby quickly providing the required data for subsequent steps, ensuring the response speed of the aerosol device, and improving the user experience.

[0093] In one implementation, a temperature coefficient of resistance (TCR) corresponding to the heating element is stored in the aerosol device, and the temperature coefficient of resistance indicates the change of the resistance value of the heating element as the element temperature value of the heating element changes; the initial parameter includes a first reference resistance value and a first reference ambient temperature corresponding to the heating element, the first parameter includes a second reference resistance value and a second reference ambient temperature corresponding to the heating element, and the target temperature is greater than the first reference ambient temperature;

[0094] The aerosol device is specifically used to obtain the first element resistance values ​​corresponding to the heating element at multiple moments during the period when the heating element heats the aerosol matrix; based on the first element resistance values, the second reference resistance values, the second reference ambient temperature and the resistance temperature coefficient corresponding to the multiple moments, the element temperatures corresponding to the heating element at multiple moments are detected; when it is detected that the aerosol matrix is ​​heated to the target temperature, the element temperatures corresponding to the multiple moments are integrated, and the integrated result is used as the total energy value.

[0095] During the period when the heating element heats the aerosol matrix, the aerosol device will collect the voltage and current of the heating element at preset time intervals through its own analog-to-digital converter (ADC) component, and determine the first element resistance of the heating element at that moment through the ratio of the voltage to the current collected at each moment. In this way, the first element resistance corresponding to multiple moments is obtained. For each moment, the aerosol device will substitute the second reference resistance, the second reference ambient temperature, the resistance temperature coefficient, and the first element resistance at that moment into Formula 1 to determine the element temperature of the heating element at that moment, thereby obtaining the element temperature corresponding to the heating element at multiple moments. Formula 1 is: T 实际 =(R1-R0) / R0*TCR+T 初始 , where T 实际 represents the component temperature, R0 represents the latest reference resistance value in the initial parameters, that is, the second reference resistance value, R1 represents the first component resistance value, TCR represents the temperature coefficient of resistance, T 初始 Indicates the latest reference ambient temperature in the initial parameters, that is, the second reference ambient temperature. It can be understood that the second reference resistance value indicates the element resistance value of the heating element at the second reference ambient temperature. When the aerosol device detects that the aerosol matrix is ​​heated to the target temperature, it will call the pre-stored energy integral calculation function, integrate the element temperatures corresponding to multiple moments, and use the integrated result as the total energy value.

[0096] In the embodiment of the present application, the total energy value of the aerosol matrix is ​​equivalent to the heat released by the heating element. The following describes the process of obtaining the total energy value of the aerosol device by integrating the element temperatures corresponding to multiple moments. According to the specific heat capacity formula Q=mcΔT, it can be known that for the heating element, the energy Q released is related to the mass m, specific heat capacity c and temperature change ΔT. In practical applications, since the mass and specific heat capacity of the heating element are fixed values, they can be combined with the time t, and the energy Q released by the heating element can be calculated by integrating the temperature change rate dT / dt over time, that is, Q=∫P(t)dt, where P(t)=mc*dT / dt, dT represents the temperature change, and dt represents the time change. In the case of discrete data, Q=∫P(t)dt can be approximated as Q≈∑mc*(T i+1 -T i ) / Δt*Δt, where T i is the component temperature collected for the i-th time, Δt is the preset time interval, T i+1 is the component temperature collected for the i+1th time, and i is a natural number. In this way, when the aerosol device detects that the aerosol matrix is ​​heated to the target temperature, the component temperatures corresponding to multiple moments and the multiple moments can be substituted into the formula Q≈∑mc*(T i+1 -T i ) / Δt*Δt to determine the total energy value.

[0097] In the above technical solution, when the heating element heats the aerosol matrix, the aerosol device detects that the aerosol matrix is ​​heated to the target temperature, based on the second reference resistance, the second reference ambient temperature, the resistance temperature coefficient and the first element resistance corresponding to the heating element at multiple moments, and integrates the element temperatures corresponding to the multiple moments to obtain the total energy value. When determining the total energy value, the dynamic change of the element temperature is considered through the integration process. Compared with the simple method of estimating energy based on the heating time and the average temperature, a more accurate total energy value can be obtained, which can adapt to the scene of different aerosol devices heating different aerosol matrices, thereby providing more reliable data for the terminal device to determine the current humidity of the aerosol matrix, thereby improving the accuracy of the subsequent current humidity.

[0098] S205, the aerosol device sends the total energy value to the terminal device.

[0099] S206: When receiving the total energy value, the terminal device detects the current humidity of the aerosol matrix based on the total energy value.

[0100] The terminal device pre-stores a correspondence between energy values ​​and humidity values, which indicates the energy values ​​corresponding to the humidity of different aerosol matrices after the aerosol matrix is ​​heated from a certain ambient temperature to a target temperature. After receiving the total energy value sent by the aerosol device, the terminal device can find out the humidity value corresponding to the total energy value from the pre-stored correspondence, and determine the found humidity value as the current humidity of the aerosol matrix.

[0101] S207: The terminal device determines a second adjustment strategy based on the current humidity.

[0102] The terminal device can determine the state of the aerosol matrix based on the relationship between the current humidity and the preset humidity limit. When it is determined that the aerosol matrix is ​​in a wet state, the second adjustment strategy can be determined to dry the aerosol matrix of the aerosol device. When it is determined that the aerosol matrix is ​​in a dry state, the second adjustment strategy can be determined to wet the aerosol matrix of the aerosol device.

[0103] In one implementation, the terminal device stores a first correspondence relationship corresponding to the aerosol device, the first correspondence relationship including humidity corresponding to a plurality of energy values ​​at a target temperature;

[0104] The terminal device is also used to determine the current humidity based on the total energy value and the first corresponding relationship; determine and output the second adjustment strategy according to the size relationship between the current humidity and the preset humidity limit.

[0105] Among them, multiple aerosol substrates of the aerosol device can be stored in a target container, and the target container can be a paper packaging box, a sealed bag, a glass container or a metal box, etc. The embodiment of the present application does not limit the specific material type and shape of the target container. The terminal device can determine the second adjustment strategy based on the current humidity of the aerosol substrate currently heated by the aerosol device, and is also used to prompt the user to make corresponding adjustments to the storage method of the remaining aerosol substrates in the target container.

[0106] The preset humidity limit includes a lower humidity limit and an upper humidity limit. The upper humidity limit can be 65%RH or 60%RH, and the lower humidity limit can be 55%RH or 50%RH. The specific values ​​of the two can be set based on the specific type of aerosol device in actual application. For example, the upper humidity limit and lower humidity limit of the herbal aerosol matrix are 60%RH and 50%RH respectively, and the upper humidity limit and lower humidity limit of the reformed aerosol matrix are 65%RH and 55%RH respectively.

[0107] The terminal device can search for the current humidity corresponding to the total energy value in the first corresponding relationship, and compare the current humidity with the lower limit value of humidity and the upper limit value of humidity respectively. When it is detected that the current humidity is less than the lower limit value of humidity, the second adjustment strategy is determined to be to wet the aerosol matrix in the target container (that is, the aerosol device), and when it is detected that the current humidity is greater than the upper limit value of humidity, the second adjustment strategy is determined to be to dry the aerosol matrix in the target container. When it is detected that the current humidity is greater than or equal to the lower limit value of humidity, and less than or equal to the upper limit value of humidity, the terminal device can remain silent or output a prompt message that no additional processing is required. In the above technical solution, the terminal device can determine and output the second adjustment strategy for the aerosol matrix of the aerosol device based on the current humidity of the aerosol matrix currently heated by the aerosol device, so that the user can be prompted in time to perform appropriate processing on the aerosol matrix in the target container, which can facilitate the user to store the aerosol matrix in a suitable environment, thereby extending the service life of the aerosol matrix.

[0108] In one implementation, the terminal device is further configured to determine and output a first adjustment strategy for the heating parameters according to a magnitude relationship between current humidity and a preset humidity threshold.

[0109] When the terminal device detects that the current humidity is less than the lower humidity limit, it determines that the aerosol matrix is ​​in a dry state. At this time, the terminal device will determine that the first adjustment strategy is to reduce the heating time of the heating element or reduce the heating power of the heating element; when the terminal device detects that the current humidity is greater than the upper humidity limit, it determines that the aerosol matrix is ​​in a wet state. At this time, the terminal device will determine that the first adjustment strategy is to extend the heating time of the heating element or increase the heating power of the heating element. When it is detected that the current humidity is greater than or equal to the lower humidity limit, and less than or equal to the upper humidity limit, it is determined that the aerosol matrix is ​​in a moderate humidity state, and the first adjustment strategy is determined to maintain the original heating parameters of the heating element unchanged. When the terminal device determines the first adjustment strategy, it will also send the first adjustment strategy to the aerosol device, so that the aerosol device can control the heating parameters of the heating element in a timely manner. It can be understood that the terminal device mainly controls the heating element to extend or reduce the heating time (or increase or decrease the heating power) during the preheating stage. The specific extended time (or increased heating power) can be 30% to 50% of the original heating time (or original heating power), and the reduced time (or reduced heating power) can be 10% to 20% of the original heating time (or original heating power). It can also be set based on the actual preheating mechanism of the aerosol device, and no specific limitation is made in the embodiments of the present application.

[0110] In the above technical solution, after receiving the total energy value sent by the aerosol device, the terminal device can quickly determine the current humidity of the aerosol matrix based on the first corresponding relationship, and determine the first adjustment strategy of the response through the simple relationship between the current humidity and the upper and lower humidity limits, so as to adjust the heating parameters in time. Through the interaction between the aerosol device and the terminal device, personalized heating of aerosol matrices with different humidity can be achieved, which can ensure the good atomization effect of the aerosol matrix, and enable the aerosol device to adapt to the humidity changes of different aerosol matrices in different environments, thereby improving the adaptability and versatility of the aerosol device.

[0111] It can be understood that the terminal device can store first correspondences and identification information corresponding to multiple other aerosol devices. When the terminal device establishes a communication connection with the current aerosol device, it can obtain the identification information of the aerosol device (for example, device transformation or name, etc.), and use the obtained identification information to find the first correspondence corresponding to the current aerosol device from the stored multiple first correspondences.

[0112] In one implementation, a second correspondence is also stored in the terminal device, and the second correspondence includes sub-second adjustment strategies corresponding to multiple humidity intervals respectively; the terminal device is also used to: when it is detected that the current humidity is less than the humidity lower limit value or greater than the humidity upper limit value, determine the target humidity interval to which the current humidity belongs in the second correspondence, and output the sub-second adjustment strategy corresponding to the target humidity interval.

[0113] In an example, taking the humidity lower limit value as 55% RH and the humidity upper limit value as 65% RH as an example, the second corresponding relationship may be as shown in Table 1 below.

[0114] Table 1

[0115]

[0116] For example, if the terminal device detects that the current humidity of the aerosol matrix is ​​76% RH, it can output the sub-second adjustment strategy corresponding to the “>75% RH” interval, which is “Put the aerosol matrix into a sealed container, add a desiccant, and place it in a cool and ventilated place for a period of time until the surface of the aerosol matrix is ​​slightly moist but not sticky when touched”, to its own display screen to remind the user to perform appropriate drying treatment.

[0117] It can be understood that the specific humidity range can be set based on the actual humidity upper limit and humidity lower limit, and the specific sub-second adjustment strategy can also be set based on the actual environmental conditions of the aerosol device. The above scheme in the embodiment of the present application is only for illustration and is not specifically limited thereto.

[0118] In the above technical solution, when the terminal device detects that the current humidity is less than the lower humidity limit or greater than the upper humidity limit, it can output a suitable sub-second adjustment strategy for the humidity range in which the current humidity is located, so that the user can adopt more detailed processing strategies for different wetness levels of the aerosol matrix, and facilitate the user's storage of the aerosol matrix, thereby improving the user's experience of using the supporting aerosol equipment.

[0119] Generally speaking, the deviation between the ambient humidity of the environment in which the aerosol device is located and the current humidity of the aerosol matrix is ​​not large, but when the humidity of the environment in which the aerosol device is located changes suddenly (for example, the geographical location of the aerosol device changes, causing the aerosol device to enter a dry environment from a humid environment, or seasonal changes, etc.), it often means that the user will also carry the target container into the same environment, but the rapid change of ambient humidity will affect the current humidity of the aerosol matrix and the humidity of the aerosol matrix in the target container. In order to further improve the reliability of the current humidity of the aerosol matrix, so as to accurately control the heating behavior of the heating element to improve the atomization effect of the aerosol matrix, in one implementation, the terminal device is also used to obtain the ambient humidity of the environment in which the aerosol device is located; determine the humidity difference between the ambient humidity and the current humidity; when it is detected that the humidity difference reaches a preset humidity threshold, the humidity corresponding to the total energy value in the first corresponding relationship is adjusted to the ambient humidity, and the value of the current humidity is adjusted to the value of the ambient humidity.

[0120] The preset humidity threshold may be 10% RH, 15% RH or 20% RH, etc. The terminal device may receive the ambient humidity input by the user, or may receive the ambient humidity sent by the aerosol device, or the terminal device itself may include a weather application and obtain the ambient humidity from the weather application. It should be noted that the humidity difference is the absolute value of the difference between the ambient humidity and the current humidity. When the terminal device detects that the humidity difference is greater than or equal to the preset humidity threshold, it determines that the humidity difference reaches the preset humidity threshold; when the terminal device detects that the humidity difference is less than the preset humidity threshold, the first corresponding relationship and the current humidity are not adjusted.

[0121] In the above technical solution, when it is determined that the humidity difference between the ambient humidity and the current humidity reaches the preset humidity threshold, the terminal device will adjust the relevant part of the first corresponding relationship and adjust the value of the current humidity to the value of the ambient humidity. In this way, the current humidity of the aerosol matrix can be close to the ambient humidity, eliminating the interference of environmental changes on the current humidity of the aerosol matrix, and more reliable data can be obtained, which provides a reliable data basis for the subsequent control of the heating behavior of the heating element and the determination of the second adjustment strategy, thereby improving the atomization effect of the aerosol matrix.

[0122] In the technical scheme of S201-S207, during the operation of the aerosol device, when the aerosol device detects the first adjustment instruction indicating the adjustment of the initial parameter, the aerosol device will adjust the initial parameter to obtain the first parameter, thereby adjusting the initial parameter of the aerosol device, thereby improving the atomization effect of the aerosol device based on the reliable first parameter. Moreover, the aerosol device can accurately determine the amount of heat absorbed by the aerosol matrix during the heating process of the heating element based on the first parameter, that is, the total energy value. In this way, the terminal device can accurately detect the current humidity of the aerosol matrix based on the accurate total energy value sent by the aerosol device, and can accurately determine and output the second adjustment strategy based on the current humidity, thereby realizing the storage method recommendation of the aerosol device for aerosol matrices of different humidity, and can prompt the user to store the aerosol matrix appropriately, so as to ensure the atomization effect of the aerosol device in subsequent use, thereby improving the user's experience.

[0123] Combination Figure 5 , taking the terminal device as a mobile phone as an example, the workflow of the control system of the aerosol device in an application scenario after a certain initial parameter adjustment is explained. S11, when the HNB device (an example of an aerosol device) is awakened (it can be the user turning on the HNB device or the HNB device being awakened from sleep mode), it will start its own Bluetooth component (an example of a communication component) to bind with the mobile phone through the Bluetooth component.

[0124] S12, the mobile phone will exchange the unique identifier (UID) code (an example of identification information) in the Flash register (an example of a storage component) of the HNB device with the HNB device to confirm the successful connection with the HNB device. Based on the UID code, the target ambient humidity function corresponding to the HNB device is determined from all ambient humidity functions stored in the mobile phone (an example of a first corresponding relationship).

[0125] S13, when the HNB device detects that the herbal stick (an example of an aerosol matrix) is inserted into the HNB device, it activates its own heating body (an example of a heating element) to heat the herbal stick.

[0126] S14, the HNB device calculates the current resistance of the heating element (an example of the resistance of the first element) based on the voltage and current collected by its own ADC component at a frequency of 100ms / time, and calculates the current resistance of the heating element according to Formula 1 (i.e. Figure 5The heating element temperature calculation function in the figure calculates the heating element's heating temperature (an example of component temperature) based on the current resistance value and the TCR coefficient (also known as the temperature coefficient of resistance) of the heating element to grasp the temperature at which the herbal stick is heated. While the heating element is heating the herbal stick, the aerosol device will also adjust the duty cycle of the pulse width modulation (PWM) signal of the heating element through its own PID temperature control component, thereby adjusting the heating temperature of the heating element so that the actual temperature of the heating element is stabilized at the target temperature.

[0127] S15, the aerosol device records the heating temperature of the heating element collected in the preheating stage, and passes the heating temperature as a parameter into the energy integral calculation function (Q≈∑mc*(T i+1 -T i ) / Δt*Δt is an example), the heating temperature and time are integrated to obtain the total energy P, and then the total energy P is sent to the mobile phone.

[0128] S16, after receiving the total energy P, the mobile phone will pass the total energy P as a parameter into its own environmental humidity function (an example of the first corresponding relationship) to obtain the current humidity I of the herbal stick.

[0129] S17, the user can manually input the humidity I0 (an example of environmental humidity) of the current environment in the application (application, app) of the mobile phone.

[0130] S18, the mobile phone can compare I and I0. If the deviation between I and I0 is large (an example in which the humidity difference reaches the preset humidity threshold), enter S19, and the mobile phone will automatically calibrate the ambient humidity function (an example in which the humidity corresponding to the total energy value in the first corresponding relationship is adjusted to the ambient humidity). Specifically, the mobile phone will change the humidity corresponding to the total energy P in the ambient humidity function from the value of I to the value of I0, and determine that the current humidity I of the herbal stick is the value of I0. Then the mobile phone enters S20, and judges whether the storage state of the herbal stick is good according to the I value. Specifically, if the mobile phone judges that the current humidity I is close to the upper limit of the reasonable humidity range (an example of the upper limit of the humidity), the mobile phone will output information on the app display interface to prompt the user to change the storage state of the herbal stick (specifically, drying treatment, an example of the second adjustment strategy); if the mobile phone judges that the current humidity I is close to the lower limit of the reasonable humidity range (an example of the lower limit of the humidity), the mobile phone will output information on the app display interface to prompt the user to change the storage state of the herbal stick (specifically, moistening treatment, another example of the second adjustment strategy). If the mobile phone judges that the current humidity I is within a reasonable range, it outputs a prompt message that the herbal stick is well stored, so as to prompt the user that the herbal stick is currently in a good storage state. If the mobile phone judges that the deviation between I and I0 is not large (an example in which the humidity difference does not reach the preset humidity threshold), it directly enters S20.

[0131] In the embodiment of the present application, during the operation of the aerosol device, the aerosol device will collect its own component parameters, and send its own component parameters and initial parameters to the terminal device, so that the terminal device can parse the state adjustment result of the aerosol device based on the received component parameters and initial parameters to adjust the operation of the aerosol device, thereby achieving the purpose of timely adjusting the operation of the aerosol device based on the component parameters of the aerosol device that reflect the current heating condition of the heating element during the operation of the aerosol device, and ensuring the atomization effect of the aerosol device, thereby improving the user's experience of using the aerosol device. In addition, the aerosol device only needs to collect component parameters and send them to the terminal device, and the terminal device can adjust the operation of the aerosol device. The state adjustment result can be quickly determined through the efficient calculation of the terminal device, and the aerosol device itself does not need to parse its own parameters, which saves the computing resources of the aerosol device and ensures the efficiency of the adjustment of the operation of the aerosol device.

[0132] The following is a detailed description of the process of adjusting the initial parameters of the control system of the aerosol device in the embodiment of the present application. Figure 6 The flowchart of the control system of another aerosol device in the embodiment of the present application is shown as follows: Figure 6 The workflow shown includes the following steps:

[0133] In one implementation, the aerosol device collects component parameters of the aerosol device during operation of the aerosol device, including S301:

[0134] S301, the aerosol device obtains a second element resistance, a first battery temperature, and a first substrate temperature.

[0135] The aerosol device includes a first resistor and a second resistor, the first resistor is used to detect the temperature of a battery in the aerosol device, and the second resistor is used to detect the temperature of a circuit substrate in the aerosol device. The second resistor is used to detect the temperature of a circuit substrate in the aerosol device. In the aerosol device, the first resistor and the second resistor are respectively connected in series with a reference resistor, and the first resistor and the second resistor can be negative temperature coefficient (NTC) resistors. The resistance value of the reference resistor can be 10 kilo ohms (kΩ), and the resistance value of the reference resistor can be comprehensively determined based on factors such as the specific circuit design of the aerosol device in actual applications, the characteristics of the NTC resistor, and the temperature detection accuracy.

[0136] The initial parameters include a first reference resistance corresponding to the heating element and a first reference ambient temperature; the component parameters include a second element resistance of the heating element at the current ambient temperature, a first battery temperature corresponding to the first resistor, and a first substrate temperature corresponding to the second resistor. The current ambient temperature is the temperature of the environment in which the aerosol device is located.

[0137] The aerosol device stores a third corresponding relationship and a fourth corresponding relationship. The third corresponding relationship includes temperatures corresponding to multiple resistance values ​​of the first resistor, and the fourth corresponding relationship includes temperatures corresponding to multiple resistance values ​​of the second resistor.

[0138] The aerosol device applies a total voltage U to the first resistor and the reference resistor, and measures the voltage of the reference resistor, and then determines the first reference resistance of the first resistor through the formula R1 = (U-U_Y) / U_Y*R_Y, where R1 represents the first reference resistance, R_Y represents the resistance of the reference resistor, and U_Y represents the voltage of the reference resistor. Similarly, the aerosol device can determine the second reference resistance of the second resistor. The aerosol device can find the temperature corresponding to the first reference resistance from the third corresponding relationship, which is the first battery temperature, and find the temperature corresponding to the second reference resistance from the fourth corresponding relationship, which is the first substrate temperature. The aerosol device also collects the voltage and current of the heating element through its own ADC component, and determines the second element resistance of the heating element through the ratio between the voltage and the current. In this way, the aerosol device obtains the second element resistance, the first battery temperature and the first substrate temperature.

[0139] In one implementation, the aerosol device is used to obtain the total number of heating cycles of the aerosol device before the heating element heats the aerosol matrix; when it is detected that the total number reaches a preset number threshold, the second element resistance, the first battery temperature and the first substrate temperature are obtained.

[0140] The heating cycle refers to the process in which the heating element completes a single heating of the aerosol matrix and the element temperature of the heating element cools down to the ambient temperature. In other words, the heating cycle refers to the process in which the aerosol device completes a preheating stage, a preheating stage, a main heating stage, a steady-state holding stage, and a cooling stage. The preset number threshold can be set based on the aging characteristics of the electronic components in the aerosol device, for example, 10 times or 20 times.

[0141] When the aerosol device detects the insertion of the aerosol matrix, it will first count the total number of heating cycles it has completed and compare the total number with the preset number threshold. When the total number is greater than or equal to the preset number threshold, it is determined that the aerosol device has been used for a period of time, and it is necessary to determine whether the initial parameters need to be adjusted before heating the aerosol matrix. At this time, the aerosol device will obtain the resistance of the second element, the temperature of the first battery and the temperature of the first substrate and send them to the terminal device, so that the terminal device can feedback to the aerosol device based on these data whether adjustment is required and the specific adjustment method. It can be understood that in order to facilitate subsequent use, the aerosol device will reset the total number to zero each time it detects that the total number reaches the preset number threshold. In this technical solution, the aerosol device can automatically detect the size between the total number of heating cycles and the preset number threshold before heating the aerosol matrix each time to determine whether to adjust the initial parameters, thereby realizing the automatic adjustment of the initial parameters of the aerosol device, allowing the aerosol device to adapt to environmental changes, thereby improving the user's experience of using the aerosol device.

[0142] In one implementation, the terminal device is also used to respond to the user's operation of selecting a parameter adjustment control and send a parameter acquisition instruction to the aerosol device. The parameter acquisition instruction is used to instruct the aerosol device to collect and send the second element resistance, the first battery temperature, and the first substrate temperature. The terminal device can display the parameter adjustment control on its own display screen, and the user can trigger the control by clicking, double-clicking, or long pressing. In this way, the terminal device can send a parameter acquisition instruction to the aerosol device to force the aerosol device to collect and send the second element resistance, the first battery temperature, and the first substrate temperature, so that the terminal device determines whether the initial parameters need to be adjusted. In this technical solution, the user can actively control the adjustment of the initial parameters through the parameter adjustment control of the terminal device, and the parameter adjustment time can be freely controlled to improve the user experience of the aerosol device.

[0143] In one implementation, the aerosol device is further used to detect whether the heating element is in a heating state when receiving a parameter acquisition instruction; when detecting that the heating element is in a heating state, control the heating element to suspend heating, and cool down the heating element; when detecting that the heating element has cooled down to the current ambient temperature, obtain the second element resistance, the first battery temperature, and the first substrate temperature. When the aerosol device is controlling the heating element to heat the aerosol matrix, if the parameter acquisition instruction is received, the parameter acquisition instruction is set to the highest priority, the heating element is controlled to interrupt its own heating state, and its own radiator is started to cool down the heating element, which can reduce the situation where the aerosol device continues to heat under incorrect initial parameters, thereby reducing the situation where the heating element overheats due to inaccurate initial parameters, thereby extending the service life of the heating element. At the same time, it can also prevent the battery from working under incorrect initial parameters, which is beneficial to protecting battery performance and extending battery life.

[0144] In one implementation, the aerosol device sends the component parameters and the initial parameters to the terminal device, including S302:

[0145] S302, the aerosol device sends the second element resistance, the first battery temperature and the first substrate temperature to the terminal device.

[0146] In one implementation, the terminal device introduction component parameters include, S303:

[0147] S303, the terminal device receives the second component resistance, the first battery temperature and the first substrate temperature.

[0148] In one implementation, the terminal device determines the state adjustment result of the aerosol device based on the component parameters and the initial parameters, including S304-S305:

[0149] S304: When the terminal device detects that the difference between the second element resistance and the first reference resistance satisfies the first condition, the terminal device selects the smaller one of the first battery temperature and the first substrate temperature to obtain a temperature to be compared.

[0150] The first condition includes that the difference between the resistance of the second element and the first reference resistance is within a preset resistance range, which can be -0.002Ω to 0.002Ω or -0.001Ω to 0.003Ω. The preset resistance range can be set based on the acceptable temperature deviation and the resistance temperature coefficient of the heating element, and the embodiment of the present application does not impose any specific restrictions. The initial parameters are stored in the storage component of the aerosol device itself.

[0151] After obtaining the second element resistance, the first battery temperature and the first substrate temperature, the terminal device will determine whether the difference between the second element resistance and the first reference resistance is within the preset resistance range. If it is within the preset resistance range, the minimum temperature is selected from the first battery temperature and the first substrate temperature as the temperature to be compared.

[0152] S305: The terminal device determines a second adjustment instruction for the first reference ambient temperature based on the magnitude relationship between the temperature to be compared and the first reference ambient temperature, and sends the second adjustment instruction to the aerosol device.

[0153] The terminal device will compare the temperature to be compared with the first reference ambient temperature. If the temperature to be compared is lower than the first reference ambient temperature, the second adjustment instruction for the first reference ambient temperature will be determined to adjust the value of the first reference ambient temperature to the value of the temperature to be compared. Otherwise, the second adjustment instruction is to maintain the value of the first reference ambient temperature unchanged. The first reference ambient temperature is adjusted only when the temperature to be compared is lower than the first reference ambient temperature, which can reduce the situation where a higher abnormal value (such as abnormality caused by aging of electronic components or data drift in the aerosol device) is set as a benchmark, and ensure that the aerosol device works based on a reliable reference ambient temperature.

[0154] In one implementation, the terminal device is further used to determine the absolute value of the difference between the first battery temperature and the first substrate temperature when it is detected that the difference between the second element resistance and the first reference resistance satisfies the first condition, and output a first alarm message when it is detected that the absolute value is greater than a preset temperature threshold, and the first alarm message is used to indicate that at least the first resistor and the second resistor are abnormal. The preset temperature threshold can be 1°C or 0.5°C, etc. If the absolute value is less than or equal to the preset temperature threshold, the step of determining the second adjustment instruction of the first reference ambient temperature based on the size relationship between the temperature to be compared and the first reference ambient temperature is entered.

[0155] In one implementation, the terminal device is further used to output a second alarm message when it is detected that the difference between the resistance value of the second element and the first reference resistance value does not meet the first condition and the heating element is not in a heating state. The second alarm message is used to indicate that the heating element of the aerosol device is abnormal. Generally speaking, the resistance value of the heating element below the Curie point changes with temperature at a smaller amplitude, and the current ambient temperature is mostly lower than the Curie point of the heating element. Therefore, when the terminal device determines that the difference between the resistance value of the second element and the first reference resistance value is not within the preset resistance range, if it is found that the heating element is not in a heating state, it means that the amplitude of the current resistance value of the heating element changing with temperature is abnormal, that is, the heating element is abnormal, and the terminal device will output the second alarm message. It can be understood that the Curie Point refers to the critical temperature at which a material undergoes a phase change when the temperature changes. Specifically, when the temperature reaches the Curie Point, the physical properties of the material (such as electrical, magnetic or thermal properties) will undergo a sudden change. In this technical solution, the terminal device can automatically detect whether the heating element is abnormal when adjusting parameters based on simple condition judgment and heating element status detection, and output a second alarm message when it is abnormal, so that the user can take timely treatment measures and improve the safety of the aerosol device. It can be understood that the first alarm message and the second alarm message can be text or graphics.

[0156] In one implementation, the terminal device is further configured to send an abnormality alarm instruction to the aerosol device when at least one of the first resistor, the second resistor, and the heating element is detected to be abnormal;

[0157] The aerosol device is also used to receive an abnormal alarm instruction, and output a third alarm message through at least one of its indicator light, vibrator, display screen and speaker based on the abnormal alarm instruction, and the third alarm message indicates that at least one of the first resistor, the second resistor and the heating element is abnormal. In this technical solution, the aerosol device can also output the alarm message in time based on the judgment of the terminal device, which helps the user to grasp the abnormal situation of the aerosol device in time.

[0158] In one implementation, the terminal device is further configured to compare the second element resistance value with the first reference resistance value when it is detected that the difference between the second element resistance value and the first reference resistance value satisfies the first condition; and determine a third adjustment instruction for the first reference resistance value when the second element resistance value is less than the first reference resistance value, and send the third adjustment instruction to the aerosol device;

[0159] The aerosol device is further used to adjust the value of the first reference resistance to the value of the second element resistance based on the third adjustment instruction when receiving the third adjustment instruction.

[0160] The third adjustment instruction is used to instruct the aerosol device to adjust the value of the first reference resistance to the value of the second element resistance. In this technical solution, when the terminal device detects that the difference between the second element resistance and the first reference resistance meets the first condition, and the second element resistance is less than the first reference resistance, it will send the third adjustment instruction to the aerosol device, so that the aerosol device adjusts the value of the first reference resistance to the value of the second element resistance in its own storage component. Otherwise, the terminal device sends an instruction to the aerosol device to maintain the value of the first reference resistance unchanged, thereby achieving reliable adjustment of the first reference resistance and ensuring that the aerosol device works under a reliable benchmark.

[0161] In one implementation, after sending the component parameters to the terminal device, the aerosol device further includes S306:

[0162] S306: When receiving the second adjustment instruction, the aerosol device adjusts the value of the first reference ambient temperature based on the second adjustment instruction.

[0163] The aerosol device may adjust the value of the first reference ambient temperature to the value of the temperature to be compared or maintain the value of the first reference ambient temperature unchanged in its storage component based on the received second adjustment instruction.

[0164] It can be understood that the second reference resistance in the embodiment of the present application is the first reference resistance after the value is adjusted, and the second reference ambient temperature is the second reference ambient temperature after the value is adjusted.

[0165] Combination Figure 7 as well as Figure 8 , continuing to take the terminal device as a mobile phone as an example, the workflow of adjusting the initial parameters of an aerosol device in an application scenario is explained. S01, when the HNB device is awakened (it can be that the HNB device detects the insertion of the herbal stick, or detects that its own button is pressed and wakes up from sleep mode), it will start its own Bluetooth component (an example of a communication component) to bind to the mobile phone through the Bluetooth component, and when the insertion of the herbal stick is detected, the heating element is called to heat it. The HNB device can adjust parameters based on the passive mode, that is, the HNB device can determine whether the initial parameters need to be adjusted by automatically counting the number of heating cycles.

[0166] S02: Each time the HNB device completes a heating cycle, it can increase the internal flag Count value by 1. The internal flag indicates the total number of heating cycles. Then, it enters S03 and stores the increased Count value in the corresponding position of the Flash. Then, it enters S04. Each time the HNB device is awakened, it can extract the Count value and compare it with the standard Sum value (an example of a preset number threshold). If the Count value is greater than the Sum value, it enters S05, starts its own diagnostic module (that is, enters the initial parameter adjustment process), and sets the Count value to 0.

[0167] S06, after the HNB device starts the diagnostic module, it will call the current resistance calculation function to output the actual resistance R1 (an example of the second element resistance) of the heating element at the current ambient temperature (an example of the current ambient temperature) by passing the data collected by the ADC component, that is, the HNB device determines the second element resistance of the heating element based on the voltage-current ratio result. The HNB device will also call the temperature calculation function (an example of the fourth corresponding relationship) of the PCB board NTC (an example of the second resistor) and the temperature calculation function (an example of the third corresponding relationship) of the battery NTC (an example of the first resistor), and determine the corresponding temperatures T0 (an example of the first substrate temperature) and T1 (an example of the first battery temperature) of the PCB board and the battery at the current ambient temperature by passing the data collected by the ADC component. Then enter S07 and send R1, T0 and T1 to the mobile phone. The mobile phone will compare the actual resistance R1 with the first reference resistance R0, S08, and determine whether the difference between R1 and R0 is reasonable (that is, whether the first condition is met).

[0168] S09, if the mobile phone judges that it is reasonable, it will continue to judge whether R1 is lower than R0. If it is, it will enter S010 and send instructions to the HNB device to adjust the value of R0 in the Flash to the value of R1, so as to be used for the subsequent calculation of the heating temperature of the heating element, and then enter S012. If it is unreasonable, it will enter S011 and send instructions to the HNB device to make the HNB device vibrate its own vibrator (an example of the first alarm information). At the same time, the mobile phone can output the abnormal information of the heating element on the app display interface (an example of the second alarm information) to prompt the user that the resistance of the heating element is abnormal.

[0169] S012, when the difference between R1 and R0 is reasonable, the terminal device will determine whether the absolute value of the difference between T0 and T1 is within a reasonable range (an example of whether the difference is greater than or equal to the preset temperature threshold). If it is reasonable, min[T0, T1] is extracted, and the process proceeds to S013, where the min value (the smaller one of T0 and T1) is compared with the ambient temperature calibrated by the HNB device (an example of the first reference ambient temperature), and then proceeds to S014, where it is determined whether the min value is lower than the ambient temperature. If it is lower than the ambient temperature, an instruction is sent to the HNB device to adjust the value of the ambient temperature to the value of the min value, and store it in the corresponding position of the Flash.

[0170] HNB equipment can also adjust parameters based on passive mode. Figure 8 , S021, the HNB device and the mobile phone establish a communication connection through the Bluetooth component, S022, the user clicks the start diagnosis option in the mobile app, S023, the mobile phone sends the corresponding string instruction (an example of a parameter adjustment instruction) to the HNB device, and the HNB device waits for it to receive it. S023, after receiving the string instruction, the HNB device returns the same string to the mobile phone and starts its own diagnostic module to execute Figure 6 The process after the HNB device starts the diagnostic module to adjust the ambient temperature and R0 in the Flash.

[0171] In the embodiment of the present application, the aerosol device can automatically obtain the first battery temperature, the first substrate temperature, and the second element resistance of the heating element at the current ambient temperature and send them to the terminal device. When the difference between the second element resistance and the first reference resistance meets the first condition, the terminal device automatically determines the second adjustment instruction based on the difference between the smaller of the first battery temperature and the first substrate temperature and the first reference ambient temperature, so that the aerosol device adjusts the value of the first reference ambient temperature, and realizes the adaptive adjustment of the initial parameters, so that the atomization effect of the aerosol device can be improved based on reliable initial parameters, thereby improving the user experience.
