[0002] The temperature of the heating element in a heating-not-burning appliance is usually determined based on the resistance temperature coefficient of the heating element. The existing calibration method for the resistance temperature coefficient is: when the heating element is not blocked, the inspector uses an infrared device to measure the temperature of the heating element, and then calibrates the resistance temperature coefficient based on the temperature measurement result. This calibration method requires external equipment, and the position where the inspector uses the infrared device to calibrate the heating element may be different each time, and the time of each calibration may also be different.

[0047] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] For easier understanding, please refer to Figure 1 In a first aspect, the present application provides a heating element calibration method, comprising:

[0049] Step 110: After receiving the calibration instruction, check whether the heating-without-combustion device meets the calibration conditions. If so, control the heating element to heat for a preset heating time with a preset temperature and a current resistance temperature coefficient.

[0050] When the heating-not-burning device is produced or used by the user, the calibration instruction can be triggered by pressing the button on the heating-not-burning device, for example, by pressing the button five times in a row; after receiving the calibration instruction, the heating-not-burning device detects whether the current state of the heating-not-burning device meets the calibration conditions. If the current state of the heating-not-burning device does not meet the calibration conditions, a prompt message can be issued to prompt that the current state of the heating-not-burning device does not meet the calibration conditions. If the current state of the heating-not-burning device meets the calibration conditions, the preset temperature and the current resistance temperature coefficient are used to control the heating element to heat for a preset heating time. Specifically, the heating element is controlled to start heating at a preset temperature and continue heating for a preset heating time. When the heating element is heated, the temperature is controlled by the current resistance temperature coefficient, and a light prompt can also be displayed when heating starts. It should be noted that when the heating element is calibrated for the first time, the current resistance temperature coefficient is the default resistance temperature coefficient; when the heating element has been calibrated, the current resistance temperature coefficient is the resistance temperature coefficient stored after the latest calibration.

[0051] In the embodiment of the present application, it is possible to detect whether the heating without burning appliance meets the calibration conditions by detecting the temperature, specifically:

[0052] Obtain the current battery temperature and main board (PCB) temperature of the heating-not-burning device, and calculate the temperature difference between the battery temperature and the main board temperature;

[0053] If the battery temperature and the mainboard temperature of the heat-not-burn appliance are both within the preset temperature range, and the temperature difference is within the preset temperature difference range, it is determined that the heat-not-burn appliance meets the calibration conditions;

[0054] If either the battery temperature or the mainboard temperature of the heating without burning appliance exceeds a preset temperature range, or the temperature difference exceeds a preset temperature difference range, it is determined that the heating without burning appliance does not meet the calibration conditions.

[0055] In the embodiment of the present application, the preset temperature range can be determined when the heating-without-burning device is cooled to a normal temperature state; the preset temperature difference range can be determined by measuring the actual temperature difference between the battery temperature and the mainboard temperature of the heating-without-burning device when it is cooled to a normal temperature state. Generally, the temperature difference between the battery temperature and the mainboard temperature of the heating-without-burning device at a normal temperature state does not exceed 1°C. It is determined whether the battery temperature and the mainboard temperature of the heating-without-burning device are within the preset temperature range, and whether the temperature difference between the battery temperature and the mainboard temperature is within the preset temperature difference range, so as to determine whether the heating-without-burning device has been cooled to a room temperature state. If it is determined that the battery temperature and the mainboard temperature of the heating-without-burning device are both within the preset temperature range, and the temperature difference is within the preset temperature difference range, it is determined that the heating-without-burning device has been cooled to a normal temperature state; if it is determined that the battery temperature of the heating-without-burning device exceeds the preset temperature range, or the mainboard temperature exceeds the preset temperature range, or the temperature difference exceeds the preset temperature difference range, it is determined that the heating-without-burning device has not been cooled to a normal temperature state, and at this time, the heating-without-burning device does not meet the calibration conditions, and the heating-without-burning device can be prompted to cool down by sound, light or vibration.

[0056] Furthermore, the amount of electricity can be detected to detect whether the heating without burning appliance meets the calibration conditions, specifically:

[0057] Detecting whether the current power of the heating-not-burning appliance is greater than or equal to a power threshold;

[0058] If so, it is determined that the heat-not-burn appliance meets the calibration conditions;

[0059] If not, it is determined that the heating without burning appliance does not meet the calibration conditions.

[0060] The power threshold may be the minimum power required for a calibration process, which may be set according to actual conditions and is not specifically limited here. The current power of the heating without burning appliance may be determined by detecting the current voltage of the heating without burning appliance. If it is determined that the current power of the heating without burning appliance is less than the power threshold, it is determined that the current power of the heating without burning appliance is insufficient, and a prompt may be provided to charge the heating without burning appliance by means of sound, light or vibration.

[0061] It should be noted that different sounds, lights of different colors, and vibrations of different frequencies can be used to prompt different information. When detecting whether the state of a heating-not-burning appliance meets the calibration conditions, the power detection can be performed first, and then the temperature detection; the temperature detection can be performed first, and then the power detection; or the power detection and temperature detection can be performed simultaneously.

[0062] Step 120: Calculate the total output energy of the heating-without-combustion appliance within a preset heating time.

[0063] Since the resistance and voltage change during heating, the present application calculates the current output energy once at a certain interval during the heating process, continuously accumulates the output energy, and obtains the total output energy after the heating is completed; the shorter the interval time, the higher the accuracy of the calculated output energy. Specifically, during the heating of the heating element, the voltage, resistance and output duty cycle of the heating element are collected at preset time intervals (such as 25ms); the output energy of the heating element within the preset time period is calculated based on the voltage, resistance and output duty cycle, and the output energy of all preset time periods within the preset heating time is accumulated to obtain the total output energy of the heating element within the preset heating time. Among them, the specific calculation formula for the output energy is:

[0064]

[0065] In the formula, Q is the output energy; U is the voltage of the heating element; R is the resistance of the heating element; D is the output duty cycle; and t is the preset time period.

[0066] Step 130: Calculate the actual resistance temperature coefficient of the heating-without-combustion device according to the difference between the total output energy and the preset standard energy.

[0067] After calculating the total output energy of the heat-without-combustion device during the preset heating time, the difference between the total output energy of the heat-without-combustion device and the preset standard energy is calculated. The preset standard energy is the total output energy of the heat-without-combustion device during the debugging stage when heating at a preset temperature for a preset heating time, and the value of the preset standard energy is flashed into the heat-without-combustion device along with the program.

[0068] The actual resistance temperature coefficient is calculated based on the difference between the total output energy and the preset standard energy and the current resistance temperature coefficient. Specifically, the difference between the total output energy and the preset standard energy is weighted by the preset proportional coefficient, and the weighted result and the current resistance temperature coefficient are summed to obtain the actual resistance temperature coefficient TCR of the heating element, that is:

[0069]

[0070] In the formula, k is the preset proportional coefficient, which is obtained through experiments during the research and development stage of the heating without burning appliance, and k is a negative number; Q1 is the total output energy during this heating; Q0 is the preset standard energy; TCR0 is the current resistance temperature coefficient.

[0071] After the actual resistance temperature coefficient is calculated, the resistance temperature coefficient may be refreshed and saved according to the actual resistance temperature coefficient obtained by calibration, thereby ending the calibration process.

[0072] The calibration method in the present application does not require the use of external equipment, nor is it easily affected by external ambient temperature and light. There is no problem of a large deviation between the obtained resistance temperature coefficient and the actual resistance temperature coefficient due to different calibration positions and times each time; moreover, the calibration can be performed when the heating element is assembled, and the heating element does not need to be exposed. Even if the heating element ages after the user has used the heating device without burning for a period of time, the aged heating element can still be recalibrated according to the current resistance temperature coefficient, thereby improving the technical problem that the prior art requires external equipment for calibration, the position and time of each calibration of the heating element using the infrared equipment may be different, which leads to a large deviation between the finally obtained resistance temperature coefficient and the actual resistance temperature coefficient, and the inability to recalibrate after the heating element has aged.

[0073] In one embodiment, after the calibration process is completed, the method may further include:

[0074] Step 140: Calibrate and verify the heat-not-burn appliance according to the actual resistance temperature coefficient.

[0075] The heating without burning appliance may be prompted whether to perform calibration verification after the appliance cools down naturally, such as by sound, light or vibration. If a calibration verification instruction is received (the calibration verification instruction may be triggered by a button on the heating without burning appliance), the actual resistance temperature coefficient is used as the current resistance temperature coefficient to return to the step of detecting whether the heating without burning appliance meets the calibration conditions;

[0076] Determine whether the difference between the total output energy of the heating element within the preset heating time and the preset standard energy calculated during the calibration verification process is within the preset energy difference range;

[0077] If yes, it is determined that the heating element calibration is successful;

[0078] If not, it is determined that the heating element calibration has failed.

[0079] In the embodiment of the present application, you can choose whether to perform calibration verification after the calibration is completed. The calibration verification process is to wait for the heating non-combustion appliance to cool naturally and then re-execute the calibration process with the updated resistance temperature coefficient. The calibration is successful based on whether the difference between the calculated total output energy and the preset standard energy is within the preset energy difference range, and the calibration verification process does not refresh the resistance temperature coefficient. When it is determined that the calibration fails, a reminder can be made by sound, light or vibration. Among them, the preset energy difference range is set according to the actual situation and is not specifically limited here.
