[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0039] Embodiment 1:

[0040] When measuring the actual temperature of the heating element, there is interference resistance, which leads to poor temperature calibration of the heating element. When temperature control is performed, the temperature control of the heating device is inaccurate, which often leads to invalid output of the power supply, such as Figure 1 As shown, this embodiment provides a smoking article heating control method based on smoking article ambient temperature calibration, including:

[0041] Obtain the internal ambient temperature of the reference point in the smoking device; and obtain the resistance value of the heating element;

[0042] The actual temperature of the heating element is determined according to the ambient temperature and the resistance value, and a preset temperature-resistance relationship model; wherein the temperature-resistance relationship model is obtained by fitting a preset first set of corresponding tables and a second set of corresponding tables; the first set of corresponding tables is a corresponding table of the ambient temperature and the resistance value of the heating element in time at a preset first standard temperature; the second set of corresponding tables is a corresponding table of the ambient temperature and the resistance value of the heating element in time at a preset second standard temperature;

[0043] According to the determined actual temperature of the heating element, the required electric energy is determined and heating control is performed.

[0044] Specifically, based on the ambient temperature correlation data of the heating element reference point, the actual temperature correlation data of the heating element is obtained, which avoids the influence of the interference resistance on the heating element during the heating process and improves the temperature calibration effect of the heating element. Furthermore, the electric energy is obtained according to the actual temperature of the heating element, which can make the temperature control of the heating smoking device more accurate and reduce the invalid output of the power supply.

[0045] The temperature coefficient of resistance (TCR) indicates the relative change in resistance when the temperature changes by 1 degree, and its unit is ppm / ℃ (i.e. 10E(-6) / ℃). It is defined as:

[0046] TCR = dR / (R.dT)

[0047] Among them, dR is the resistance difference; R.dT is the relative temperature difference.

[0048] In practical applications, the average resistance temperature coefficient is usually used, which can be defined as:

[0049] TCR (average) = (R2-R1) / R1(T2-T1)

[0050] Among them, R2 and R1 are the resistance values ​​corresponding to temperature T2 and temperature T1; the obtained TCR is the corresponding value between temperature T2 and temperature T1.

[0051] In engineering applications, heating element manufacturers usually provide the corresponding resistance and TCR values ​​at 25°C. Using the above formula, the resistance value at the target temperature can be obtained. Heating tobacco products use the resistance temperature coefficient of the heating element for temperature detection and control. For example, the resistance value of the heating element at 350°C is 1.48Ω. When performing temperature control, the circuit system will increase the resistance of the heating element and maintain it at 1.48 ohms.

[0052] According to the rapid heating rate of the smoking device, the battery load capacity and the manufacturing process of the heating element, the resistance of the heating element at room temperature needs to be controlled at 0.7-0.85Ω, and the TCR is controlled between 2000-3300ppm / ℃. Limited by the level of production technology, the resistance error of the heating element at room temperature is ±0.075, and the TCR error is ±150ppm / ℃. This error seriously exceeds the temperature control accuracy requirements of the heating smoking device. Take the resistance R1=0.775Ω and TCR=2800ppm / ℃ at room temperature of 25℃ as an example for calculation, as shown in Table 1.

[0053] Table 1: Temperature resistance relationship comparison table

[0054]

[0055] For example, at 350℃, when R1=0.775Ω and TCR=2800ppm / ℃, the resistance value corresponding to 350℃ is 1.48025Ω. Based on the maximum value of the resistance value at room temperature and the TCR error, when R1=0.7Ω and TCR=2650, the temperature corresponding to the resistance value of 1.48025Ω is 446℃, and when R1=0.85Ω and TCR=2950, ​​the temperature corresponding to the resistance value of 1.48025Ω is 277℃. It can be seen that the theoretical error caused by the resistance value at room temperature and TCR is ±70℃, which is far beyond the allowable error of the temperature control accuracy of the smoking device.

[0056] In view of this, if Figure 1As shown, this embodiment provides a heating control method for a heated smoking device, and the heated smoking device may include a heating chamber, a heating element, a power supply, a power supply chamber, and a control component, etc.; the heating element is used to heat the aerosol-forming matrix contained in the heating chamber during operation to generate an aerosol, and the resistance of the heating element changes with the temperature of the heating element; the power supply chamber is used to contain the power supply; the control component is used to control the power transmitted to the heater during operation; the control component includes a first memory for storing a temperature conversion program, and a second memory for storing a heating temperature timing control program. The heating control method may include the following steps:

[0057] S1. The control component obtains data related to the ambient temperature at a reference point near the heating element in the heating device.

[0058] Optionally, the data associated with the ambient temperature within the reference point may refer to the temperature of a temperature sensor set in the environment within the reference point, or a physical quantity related to temperature; for example: the resistance value of electronic components in the environment within the reference point, the voltage and current values ​​of the circuit, etc., or data whose physical parameters may change with temperature, for example: an expansion thermometer made based on the principle of thermal expansion, the expansion length of the expansion thermometer may also be the data associated with the ambient temperature within the reference point.

[0059] In summary, the ambient temperature correlation data within the reference point can be a data type that reacts to temperature according to physical quantity transformation. The above exemplary parameters can be applied to the present application, but the present application is not limited thereto.

[0060] S2. The control component obtains data related to the measured resistance of the heating element.

[0061] Optionally, the data related to the resistance of the heating element can be measured by a functional circuit preset inside the heating smoking device. For example, a resistance measurement circuit is set inside the heating smoking device to measure the data related to the resistance of the heating element.

[0062] It should be noted that the specific configuration of the resistance measurement circuit is a technology well known to those skilled in the art and will not be described in detail here.

[0063] In another embodiment, a resistance testing device independent of the outside of the heating device can be provided to measure the data related to the resistance of the heating element, and the data related to the resistance of the heating element can be transmitted to the control component.

[0064] The data associated with the measured resistance of the heating element may include the ambient temperature at the reference point, the heating time, and other related data reflecting the measured resistance of the heating element.

[0065] S3. The control component calls the temperature conversion program and obtains the actual temperature related data of the heating element according to the internal environment temperature related data and the heating element measured resistance related data.

[0066] Optionally, the temperature conversion program may include a temperature-resistance relationship model, and the construction of the temperature-resistance relationship model includes the following steps:

[0067] S3.1. Start the heating device so that the actual temperature of the heating element reaches and is maintained at the first standard temperature.

[0068] S3.2. At different heating times, the data associated with the internal environment temperature and the data associated with the measured resistance of the heating element are recorded respectively to form a first set of corresponding tables.

[0069] In some embodiments, the construction of the temperature-resistance relationship model further includes the following steps:

[0070] S3.3. Start the heating device so that the actual temperature of the heating element reaches and is maintained at the second standard temperature.

[0071] S3.4. At different heating times, the data associated with the internal environment temperature and the data associated with the measured resistance of the heating element are recorded respectively to form a second set of correspondence tables.

[0072] In some embodiments, the temperature-resistance model includes a first set of correspondence tables and a second set of correspondence tables.

[0073] Exemplarily, the heating device is started so that the actual temperature of the heating element reaches 350 degrees Celsius, and the internal environment temperature correlation data and the corresponding heating element measured resistance correlation data of the heating element at 350 degrees Celsius can be periodically recorded according to a recording cycle with a set time interval of 20 seconds to form Table 2.

[0074] Table 2: Correlation data of internal ambient temperature when the heating element is at 350 degrees Celsius and the corresponding heating element measured resistance value

[0075]

[0076] In some embodiments, the heating device is started so that the actual temperature of the heating element reaches 380 degrees Celsius, and the internal environment temperature correlation data and the corresponding heating element measured resistance correlation data at 380 degrees Celsius can be periodically recorded according to a recording period set at a time interval of 20 seconds to form Table 3.

[0077] Table 3: Correlation data of internal ambient temperature when the heating element is at 380 degrees Celsius and the corresponding heating element measured resistance value

[0078]

[0079] In some embodiments, when the temperature conversion program is called by the control component, the following steps are performed:

[0080] S3.5. According to the internal environment temperature correlation data obtained by the control component, the measured resistance value of the heating element at the corresponding first standard temperature and the measured resistance value of the heating element at the corresponding second standard temperature are respectively obtained from the first group of corresponding tables and the second group of corresponding tables.

[0081] S3.6. Calculate the actual temperature-related data of the heating element according to the measured resistance value of the heating element at the first standard temperature, the measured resistance value of the heating element at the second standard temperature, and the measured resistance-related data of the heating element obtained by the control component.

[0082] It can be understood that based on the measured resistance of the heating element and the related data of the measured resistance of the heating element, the related data of the actual temperature of the heating element can be inferred, ignoring the influence of interfering resistances such as the circuit board resistance, solder point resistance, and heating element pin resistance during the heating process.

[0083] In some embodiments, the construction of the temperature-resistance relationship model also includes the following:

[0084] Data fitting is performed based on the first standard temperature, the first set of corresponding tables, the second standard temperature and the second set of corresponding tables to determine the relationship of "internal environment temperature correlation data-heating element measured resistance correlation data-heating element actual temperature".

[0085] In some embodiments, when the temperature conversion program is called by the control component, the following is performed:

[0086] The internal environment temperature correlation data obtained by the control component and the heating element measured resistance correlation data obtained by the control component are imported into the "internal environment temperature correlation data-heating element measured resistance correlation data-heating element actual temperature" relationship formula to deduce the heating element actual temperature correlation data.

[0087] It should be noted that the specific implementation process of calculating the data associated with the actual temperature of the heating element based on the resistance value and the data associated with the resistance value is well known to those skilled in the art and will not be described in detail here.

[0088] In some embodiments, the heating temperature curve of the heating element can be adjusted and controlled by using the calculated data related to the actual temperature of the heating element.

[0089] The heating temperature curve of the heating element describes the temperature change trend of the heating element from the initial state to the stable working state. This curve is very important for understanding and controlling the working performance of the heating element.

[0090] The heating temperature curve of the heating element can be roughly divided into the following stages:

[0091] Initial stage: In this stage, the heating element has just started to heat up and the temperature rises rapidly. At this time, due to the large temperature difference between the heating element and the surrounding environment, the heat transfer rate is fast, so the temperature inside the smoking device rises faster.

[0092] Acceleration stage: As the heating continues, the temperature of the heating element continues to rise, but the rate of increase in the ambient temperature inside the smoking device gradually slows down. This is because as the temperature rises, the temperature difference between the heating element and the surrounding environment gradually decreases, and the rate of heat transfer also decreases accordingly.

[0093] Stable stage: When the heating element reaches a certain temperature, its heating speed will tend to be stable and the temperature curve will become relatively gentle. At this time, the heat generated by the heating element and the heat dissipated reach a balance, and the ambient temperature inside the smoking device remains at a relatively stable level.

[0094] It should be noted that the heating rate of the heating element changes from fast to slow over time because the difference between the actual temperature and the set target temperature is getting smaller and smaller, and the program controls the output power. Those skilled in the art can also make specific settings according to actual application scenarios.

[0095] It is understandable that the specific heating temperature curve will be affected by many factors, including the material, shape, size, heating power, ambient temperature, heat dissipation conditions, etc. of the heating element. Therefore, the present application can adjust and control the heating temperature curve of the heating element through the actual temperature correlation data of the heating element to improve the best heating effect and stability.

[0096] S4. The control component calls the heating temperature timing control program and controls the electric energy transmitted to the heater by the power supply according to the actual temperature correlation data of the heating element.

[0097] It can be understood that by obtaining the ambient temperature correlation data within the reference point of the heating element, and based on the ambient temperature correlation data within the reference point of the heating element, the actual temperature correlation data of the heating element is obtained, thereby avoiding the influence of interference resistance on the heating element during the heating process and improving the control effect of the heating temperature of the heating element.

[0098] Embodiment 2:

[0099] This embodiment provides a smoking device, including a control component, a power supply and a heater; the control component is used to control the electric energy output by the power supply to the heater; when the control component is working, the steps of the smoking device heating control method based on smoking device ambient temperature calibration as described in Example 1 are implemented.

[0100] Specifically, the smoking device is a heating smoking device, including a heating chamber, a heating element, a power supply, a power supply chamber and a control component, etc. The heating element is used to heat the aerosol-forming matrix contained in the heating chamber to generate an aerosol when working; the resistance of the heating element changes with the temperature of the heating element; the power supply chamber is used to accommodate the power supply; the control component is used to control the electric energy transmitted by the power supply to the heater when working; the control component includes a first memory for storing a temperature conversion program and a second memory for storing a heating temperature timing control program; the heating smoking device also includes an internal environment temperature sensor element arranged at a reference point near the heating element in the heating smoking device, and the control component is used to execute the heating control method as described above.

[0101] In some embodiments, the internal environment temperature sensor element is disposed close to the pin solder joint of the heating element or close to the circuit element.

[0102] In some embodiments, the sensing element is a patch temperature sensor.

[0103] It can be understood that the SMD temperature sensor usually consists of three parts: temperature sensing element, signal conditioning circuit and output interface. Its core component is the temperature sensing element, which is responsible for sensing the change of ambient temperature. Common temperature sensing elements include thermistors (such as PTC and NTC) and thermistor capacitors. The working principle of these components is based on the thermal effect, that is, their resistance value changes with the change of temperature. For example, the resistance value of NTC thermistor decreases when the temperature increases, while the resistance value of PTC thermistor increases when the temperature increases.

[0104] like Figure 2 As shown, the heating element 1 is connected to the circuit board 3, and the sensor element 2 can be arranged on the circuit board 3 near the heating element pin solder joint 4. This method can respond to the temperature changes of the heating element pin and the circuit board 3 more quickly.

[0105] like Figure 3 As shown, due to the limitations of temperature, component arrangement and other conditions, the sensor element 2 is not suitable to be set too close to the heater pin solder joint 4. In this case, the sensor element 2 can be placed next to the key circuit 5 related to the heater temperature control to facilitate the sensor element 2 to measure temperature-sensitive circuit devices, such as power amplifiers, MOS tubes, etc.

[0106] The above description is only a preferred embodiment of the present embodiment and is not intended to limit the present embodiment. For those skilled in the art, the present embodiment may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present embodiment shall be included in the protection scope of the present embodiment.
