More specifically, the present application discloses a method for calibrating the temperature control parameters of a heater and a related device. Background Art

[0002] Electronic atomization devices include electronic cigarettes, air humidifiers, atomization drug delivery systems, etc. Electronic atomization devices use the heater of the atomization component to heat and atomize the atomization liquid (such as water, liquid medicine, atomization oil, etc.) to form an aerosol for users to inhale.

[0003] At present, electronic atomization devices usually use a TCR temperature control model based on the resistance-temperature relationship to control the temperature of the heater during the heating process. However, in actual applications, as the use of electronic atomization devices continues to deepen, the heating consistency of the heater will gradually not be guaranteed. If the original TCR temperature control model is still used for temperature control, the temperature control accuracy of the electronic atomization device cannot be fully guaranteed, which reduces the user's aerosol inhalation experience.

[0004] It is worth noting that the techniques described in this section are not necessarily techniques that have been previously conceived or employed. Unless otherwise indicated, it should not be assumed that any technique described in this section is considered to be prior art simply because it is included in this section.

[0006] A first aspect of the present application provides a method for calibrating temperature control parameters of a heater, which is applied to an electronic atomization device. The electronic atomization device is equipped with a heater and a temperature sensor for collecting the temperature of the heater. The method for calibrating temperature control parameters of the heater includes: in the process of controlling the operation of the heater using a TCR temperature control model, when the actual resistance of the heater reaches a target resistance corresponding to a preset target heating temperature, obtaining the actual sampling temperature of the temperature sensor; combining the actual sampling temperature and the target heating temperature, determining whether a preset heater temperature control parameter calibration condition is met; if the heater temperature control parameter calibration condition is met, calibrating the target temperature control parameter associated with the TCR temperature control model.

[0007] A second aspect of the present application provides a heater temperature control parameter calibration device, which is applied to an electronic atomization device, wherein the electronic atomization device is equipped with a heater and a temperature sensor for collecting the temperature of the heater, and the heater temperature control parameter calibration device includes: an acquisition module, which is used to acquire the actual sampling temperature of the temperature sensor when the actual resistance of the heater reaches the target resistance corresponding to the preset target heating temperature during the process of controlling the operation of the heater using the TCR temperature control model; a judgment module, which is used to judge whether the preset heater temperature control parameter calibration conditions are met in combination with the actual sampling temperature and the target heating temperature; and a calibration module, which is used to calibrate the target temperature control parameters associated with the TCR temperature control model if the heater temperature control parameter calibration conditions are met.

[0008] The third aspect of the present application provides an electronic atomization device, comprising: a memory and a processor, wherein the processor is used to execute a computer program stored in the memory, and when the processor executes the computer program, it implements the various steps in the heater temperature control parameter calibration method provided in the first aspect of the present application.

[0009] The fourth aspect of the present application provides a computer-readable storage medium on which a computer program is stored.

[0018] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0019] In the description of the embodiments of the present application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In addition, in the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0020] In practical applications, the heater used in electronic atomization equipment is usually made of metal materials with a high temperature coefficient of resistance (TCR) or ceramic materials with metal paste printed on the surface. There are many types of shapes, such as sheet and rod. In practical applications, the heater follows the following TCR temperature control model when performing temperature control: TCR = (R n -R0) / (R0×(T n -T0))=(R n -R0) / (R0×△T), where TCR represents the temperature coefficient of resistance, T0 represents the ambient temperature of the heater, and T n It indicates the target heating temperature that the heater is expected to heat to, R0 is the resistance of the heater when the temperature is T0, that is, the initial resistance, R n The temperature is T n The target resistance value of the heater, T0 and R0 are recorded and saved in the storage chip of the electronic atomization device when leaving the factory. When the heater needs to be heated, due to T n , T0, R0 and TCR are known, so R can be calculated by the above relationship n Then, in the actual heating process, the series circuit current is calculated by the sampling resistor and the sampling resistor voltage divider, and the actual resistance of the heater is calculated based on the current and the heater voltage divider. Then, referring to the actual resistance and the target resistance, it is only necessary to control the output power to keep the resistance of the heater at R n , the temperature control function can be realized.

[0021] like Figure 1 The figure shows a schematic diagram of the corresponding relationship between the temperature and resistance of a heater provided in this embodiment. It can be seen from the figure that different heater resistances correspond to different heating temperatures. In practical applications, the purpose of controlling the temperature can be achieved by controlling the heater resistance. However, as the number of working times and working time of the electronic atomization device increase, when the initial resistance preset for the heater no longer reflects the actual resistance in its initial state, if the original TCR temperature control model is still used for heating control, the temperature control accuracy in the actual heating process will decrease.

[0022] In order to solve the problem that the electronic atomization device provided by the related art cannot always guarantee the accuracy of temperature control as the depth of use deepens, an embodiment of the present application provides a method for calibrating the temperature control parameters of the heater of the atomization device, which is applied to the control system of the electronic atomization device. The electronic atomization device includes an atomizer, and the atomizer is provided with a heater, such as Figure 2The figure shows a functional module diagram of a control system of an electronic atomization device provided in this embodiment. The control system includes: an MCU control system (that is, a processor) and an output module. The MCU control system is used as a core module to control the normal operation of the entire system, detect battery power, detect heater resistance, status display, etc.

[0023] When receiving the start command, the MCU control system detects the start signal and starts each circuit module according to the start signal to put it into working state. When the user draws the electronic atomization device, due to the effect of airflow, the aerosol formed by the atomization liquid on the heater at the target temperature is inhaled by the user. At the same time, the MCU control system can drive the LED to output the corresponding light display, provide normal working prompts or abnormal prompts, etc.

[0024] In the actual working process, the MCU control system controls the output control module to add electric energy to the heater to make it heat up. At the same time, the resistance detection module detects the resistance of the heater in real time and transmits the resistance information to the MCU control system in real time. The MCU control system calculates the real-time temperature of the heater based on the temperature control principle through the relationship between the preset initial temperature and initial resistance and the real-time detected resistance.

[0025] Specifically, the control system of the electronic atomization device may also include but is not limited to a key start module, a lithium battery protection module, a charging management module, and an LED display module that are directly or indirectly electrically connected to the MCU control system.

[0026] Among them, the button start module is used to input a start or shutdown signal so that the MCU control system controls each circuit module to enter a working state or a shutdown state according to the start or shutdown signal.

[0027] The lithium battery protection module is used to protect the battery charging and discharging, and to detect the battery parameters such as charging current, voltage and discharge current in real time, to achieve over-discharge protection, over-current protection, short-circuit protection and over-charge protection, etc., to play a role in safety protection and prolonging service life.

[0028] The charging management module is used to replenish the battery when the battery power is low.

[0029] The LED display module is used to display the status of the product, such as full power, empty power, inhalation or abnormal status.

[0030] The resistance detection module is used to monitor the change of the resistance of the heater and feed the information back to the MCU control system. The MCU control system can calculate the temperature of the heater based on the relationship between the preset temperature and resistance.

[0031] The MCU control system can heat the heater through the output control module, and indirectly control the temperature of the heater by controlling the output power of the output control module.

[0032] like Figure 3 The basic flow chart of the method for calibrating the temperature control parameters of a heater provided in one embodiment of the present application is applied to an electronic atomization device equipped with a heater and a temperature sensor for collecting the temperature of the heater. The method for calibrating the temperature control parameters of the heater specifically includes the following steps:

[0033] Step 301: in the process of controlling the operation of the heater by using the TCR temperature control model, when the actual resistance value of the heater reaches the target resistance value corresponding to the preset target heating temperature, the actual sampling temperature of the temperature sensor is obtained.

[0034] Specifically, when the electronic atomizer leaves the factory, a certain period of continuous and stable operating temperature is used as the initial reference (temperature fluctuation within 30 seconds is less than ±1°C). At this time, the sampling temperature of the temperature sensor (such as a thermocouple) is T r0 At this time, the resistance of the heater is detected to be R 02 , record the resistance and temperature at room temperature as R 01 and T 01 , combined with the resistance temperature coefficient TCR, through the TCR temperature control model T Z0 =T 01 +(R 02 -R 01 ) / (R 01 ×TCR) to calculate the actual working temperature T of the heater at this time Z0 Usually, the true temperature and the temperature measured by the thermocouple have the following relationship: △T = T Z0 -T r0 = b0, where b0 is a fixed temperature difference caused by factors such as heat dissipation. It should be noted that the temperature sensor is usually attached to the outer surface of the heater, and the sampled temperature of the temperature sensor can feedback the real temperature of the heater to a certain extent. In actual application, the sampled temperature change of the temperature sensor usually lags behind the real temperature change of the heater, and due to heat dissipation, the sampled temperature of the temperature sensor is lower than the real temperature of the heater.

[0035] Step 302: Based on the actual sampling temperature and the target heating temperature, determine whether the preset heater temperature control parameter calibration conditions are met.

[0036] Specifically, in this embodiment, the actual sampling temperature, the target heating temperature and the preset temperature difference can be combined to determine whether the preset temperature comparison relationship is established; if the temperature comparison relationship is established, it is determined that the preset heater temperature control parameter calibration condition is met. The temperature comparison relationship is expressed as:

[0037] |T Z0 -T r1 -b0|≥△T;

[0038] Among them, T Z0 Indicates the target heating temperature, T r1 represents the actual sampling temperature, b0 represents the temperature difference, and △T represents the preset temperature difference threshold;

[0039] It should be noted that as the heater continues to work, the initial resistance R 01 Will change to R 11 , the original TCR temperature control model is used to calculate the working temperature of the heater at this time: T Z1 =T 01 +(R 02 -R 11 ) / (R 11 ×TCR), the heater operating temperature at this time is T Z1 The deviation from the target heating temperature T Z0 , the actual sampling temperature T detected by the temperature sensor r1 The standard sampling temperature T corresponding to the deviation from the target heating temperature r0 At this time, it is determined whether the above temperature comparison relationship is established. In practical applications, △T can preferably be 5°C, |T Z0 -T r1 -b0|≥5℃, it means that the temperature control accuracy of the TCR temperature control model based on the original configuration can no longer meet the requirements, and the TCR temperature control model needs to be calibrated. It should be understood that the selection of the above critical value of 5℃ is related to the product taste-temperature sensitivity, the temperature measurement accuracy of electronics and thermocouples, and the critical value is required to be less than or equal to 5℃ to ensure the consistency of taste throughout the process.

[0040] In an optional implementation of this embodiment, physical characteristic indicators and / or working environment indicators of the heater may be obtained; and the temperature difference may be determined based on the physical characteristic indicators and / or working environment indicators.

[0041] Specifically, the b0 value is the actual test value of each product, which is closely related to the thickness of the heater, thermal conductivity, HNB product size, heat dissipation, product use environment temperature, etc. Among them, the greater the thickness, the smaller the thermal conductivity, the smaller the size, the greater the heat dissipation, or the lower the ambient temperature, the greater the b0 value. In actual application, the test method is to test multiple sets of data in a low temperature environment (for example, 0-5°C) and a high temperature environment (for example, 35-40°C), and take the average of the two as the b0 value of the product.

[0042] Step 303: If the heater temperature control parameter calibration condition is met, the target temperature control parameter associated with the TCR temperature control model is calibrated.

[0043] Specifically, as the number of working times and working time of the electronic atomization device continue to increase, with the same target resistance value as the reference standard for TCR temperature control, the actual temperature that the heater can heat to gradually becomes lower than the target heating temperature of the original configuration. At this time, it is necessary to calibrate the parameters of the TCR temperature control model so that the heater can still be heated to the target heating temperature. In the subsequent working process, the calibrated TCR control model is used for temperature control to ensure temperature control consistency.

[0044] In an optional implementation manner of this embodiment, the specific implementation manners of calibrating the target temperature control parameters associated with the TCR temperature control model include but are not limited to the following three:

[0045] Method 1: Determine a new target heating temperature based on the target heating temperature, the actual sampling temperature, the preset temperature difference, and the actual heating temperature corresponding to the actual resistance value; and calibrate the target heating temperature associated with the TCR temperature control model using the new target heating temperature.

[0046] The calculation formula of the above new target heating temperature is expressed as:

[0047] T Z2 =T Z1 -(T Z0 -T r1 -b0);

[0048] Among them, T Z2 represents the new target heating temperature, T Z1 Indicates the actual heating temperature, T Z0 Indicates the target heating temperature, T r1 represents the actual sampling temperature, and b0 represents the temperature difference.

[0049] Specifically, in actual applications, due to the change in the initial resistance of the heater, the actual heating temperature when the target resistance is reached deviates from the target heating temperature. The target heating temperature originally configured in this embodiment cannot form an effective reference for temperature control. Therefore, the originally configured target heating temperature can be corrected to indirectly correct the temperature control deviation introduced by the initial resistance error.

[0050] Method 2: When the actual sampling temperature of the temperature sensor reaches the standard sampling temperature corresponding to the target heating temperature, the current first test resistance of the heater is obtained; the calibration resistance is determined based on the first test resistance, the target heating temperature and the preset ambient temperature; and the initial resistance associated with the TCR temperature control model is calibrated using the calibration resistance.

[0051] The calculation formula of the above calibration resistance is expressed as:

[0052] R 11 =R M1 -(T Z0 -T01 )×TCR×R 11 ;

[0053] Among them, R 11 Indicates the calibration resistance, R M1 Indicates the first test resistance, T Z0 Indicates the target heating temperature, T 01 It represents the ambient temperature of use and TCR represents the temperature coefficient of resistance.

[0054] Specifically, due to the change in the initial resistance, the target resistance actually corresponding to the target temperature will change. This embodiment can control the heater to heat to the target temperature by measuring the temperature with a temperature sensor, and then detect the current test resistance of the heater, that is, the test resistance of the heater is the correct target resistance to reach the target temperature. Then, this embodiment substitutes the test resistance into the calculation formula of the calibration resistance, and can calculate the correct initial resistance corresponding to the correct target resistance. The initial resistance of the original configuration is corrected as the calibration resistance, and the initial resistance error can be directly corrected to ensure the accuracy of temperature control. It should be noted that in order to ensure the accuracy of the calibration resistance calculation, this embodiment can obtain the first test resistance only when the fluctuation amplitude of the actual sampling temperature of the temperature sensor within the preset time is less than the preset temperature range (for example, [-5°C, +5°C]) before obtaining the current first test resistance of the heater, so as to ensure the validity of the first test resistance obtained.

[0055] Method three, obtaining the test temperature and the second test resistance of the heater in the room temperature cooling state; determining the calibration resistance based on the test temperature, the second test resistance and the preset ambient temperature of use; and calibrating the initial resistance associated with the TCR temperature control model using the calibration resistance.

[0056] The calculation formula of the above calibration resistance is expressed as:

[0057] R 11 =R a +(T 01 -T a )×(R a ×TCR);

[0058] Among them, R 11 Indicates the calibration resistance, R a Indicates the second test resistance, T a Indicates the test temperature, T 01 It represents the ambient temperature of use and TCR represents the temperature coefficient of resistance.

[0059] Specifically, different from the previous initial resistance calibration method, this embodiment can also obtain the resistance and temperature of the heater at room temperature when the heater is in a cooling state, and then calculate the test resistance based on the above-mentioned calibration resistance calculation formula to correct the initial resistance of the original configuration. It can also directly correct the initial resistance error to ensure the accuracy of temperature control.

[0060] It is worth noting that, in this embodiment, after the parameters of the TCR temperature control model are calibrated in the aforementioned manner, the calibration validity test can be performed through the calibrated TCR temperature control model, that is, the temperature comparison relationship |T is determined by combining the actual sampling temperature, the target heating temperature and the preset temperature difference. Z0 -T r1 -b0|≥△T is established. If so, it is confirmed that the TCR temperature control model has been effectively calibrated. Otherwise, the above calibration method is repeated until the effective calibration is completed.
