Description

Technical Field

[0001] The present application relates to the field of temperature control technology, and more specifically, to a heating control device and method for an electronic cigarette. Background Art

[0002] Temperature control refers to the process of maintaining or achieving the desired temperature under specific conditions by adjusting equipment or strategies. Its main purpose is to ensure that the temperature remains within the set range to meet the needs of specific applications or operations while preventing safety hazards caused by abnormal temperatures.

[0003] An electronic cigarette is a device that imitates traditional cigarettes. It heats the e-liquid through a heating element to generate steam for users to inhale. Electronic cigarette heating temperature control refers to ensuring that the evaporation temperature of the e-liquid remains within an ideal range by precisely adjusting the temperature of the heating element. This control is mainly used for temperature protection mechanisms to prevent safety hazards caused by overheating. In existing electronic cigarette heating temperature control technologies, the temperature of the heating element is monitored in real time, and then the current or voltage is adjusted to keep the heating element within a set temperature range. However, when the air holes of the electronic cigarette open and close quickly, the airflow and airflow velocity during electronic cigarette smoking also change rapidly. If the temperature of the electronic cigarette is adjusted only by current or voltage, the heating element of the electronic cigarette will respond slowly or overreact, and the heating element's response to temperature will be out of control, resulting in excessive heating of the electronic cigarette. Therefore, how to reduce the impact of the hysteresis response of the electronic cigarette heating element on temperature control during the heating process of the electronic cigarette has become a difficult problem faced by the industry.

[0065] The hot end boundary of the high temperature zone of the electronic cigarette during the heating process is determined according to the high temperature area.

[0066] In specific implementation, collecting all temperature values ​​of the electronic cigarette during the heating time period can be achieved in the following manner, namely: monitoring the temperature of the electronic cigarette during the heating time period by a temperature sensor arranged in the electronic cigarette; wherein the heating time period refers to the time period from the start of heating to the end of heating of the electronic cigarette, which will not be repeated here.

[0067] In specific implementation, the following method can be used to construct a temperature histogram based on all temperatures, namely: arrange all temperature values ​​in ascending order, use the arranged sequence as the temperature value sequence, divide the temperature value sequence from left to right at intervals of 5°C, and obtain multiple temperature value intervals. For example, the temperature value sequence is (15, 16, 17, 18, 20, 26, 30), and the temperature value intervals obtained by dividing from left to right at intervals of 5°C are (15, 16, 17, 18, 20) and (26, 30). The temperature value intervals are used for analysis and reasoning.

The temperature characteristic of the electronic cigarette during the heating process is the law and key point of the temperature change of the electronic cigarette during the heating process; the low temperature area and the high temperature area of ​​the electronic cigarette can be determined according to the temperature histogram and the temperature characteristic, which can be implemented in the following manner, namely: all temperature value intervals with a temperature lower than the preheating temperature in the temperature histogram are taken as the low temperature area of ​​the electronic cigarette, and all temperature value intervals with a temperature higher than the peak temperature in the temperature histogram are taken as the high temperature area of ​​the electronic cigarette, wherein the low temperature area is the temperature range of the electronic cigarette when it just starts to heat up, and the high temperature area is the temperature range of the electronic cigarette under continuous high-power heating; the cold end boundary of the low temperature area of ​​the electronic cigarette during the heating process can be determined according to the low temperature area, which can be implemented in the following manner, namely: the average of all temperature values ​​in the interval with the largest total number of temperature values ​​in the low temperature area is taken as the cold end boundary of the low temperature area; the hot end boundary of the high temperature area of ​​the electronic cigarette during the heating process can be determined according to the high temperature area, which can be implemented in the following manner, namely: the average of all temperature values ​​in the interval with the largest total number of temperature values ​​in the high temperature area is taken as the hot end boundary of the high temperature area; in other embodiments, other methods can also be used for determination, which are not limited here.

[0068] It should be noted that the cold end boundary in the present application is the critical point of the temperature range of the electronic cigarette in the initial stage of heating, which is used to determine the conditions for the electronic cigarette to increase the heating temperature; the hot end boundary is the critical point of the high temperature range where the temperature of the electronic cigarette gradually tends to stabilize from rising, which is used to determine the conditions for the electronic cigarette to stop heating and over-temperature protection, so as to facilitate the precise control of temperature in different temperature ranges.

[0070] In some embodiments, reference Figure 2 As shown, this figure is a schematic diagram of the process of determining the dynamic thermal response in some embodiments of the present application. In this embodiment, based on the opening and closing range of the electronic cigarette pores and the cold end boundary, the heating element in the electronic cigarette is subjected to airflow step excitation, and the dynamic thermal response of the heating element under the change of the pore opening and closing degree can be obtained by the following steps:

[0075] Finally, in step 1025, the dynamic thermal response of the heating element under the change of the pore opening and closing degree is determined according to all the temperature change amounts and all the heat capacity change information.

[0077] In specific implementation, the temperature change amount of the heating element after each change in the pore opening degree can be determined according to the step response information in the following manner, namely: when the electronic cigarette is turned off and cooled, the temperature sensor is used to obtain the initial temperature of the heating element; a pore opening degree is selected as the selected pore opening degree, and the temperature value corresponding to the selected pore opening degree in the step response information is subtracted from the initial temperature value of the heating element, and the value obtained by subtraction is used as the temperature change amount of the heating element under the selected pore opening degree, and the temperature change amount of the heating element under the remaining pore opening degrees is continued to be determined, wherein the temperature change amount is the temperature change amount of the heating element under the change of the pore opening degree. Parameter value of the situation; determining the heat capacity change information of the heating element after each change in the pore opening and closing according to the step response information can be achieved in the following manner, namely: selecting a pore opening and closing as the selected pore opening and closing, and taking the set consisting of the cross-sectional area and the corresponding length corresponding to the selected pore opening and closing in the step response information as the heat capacity change information of the heating element under the selected pore opening and closing, and continuing to determine the heat capacity change information of the heating element under the remaining pore opening and closing; wherein, the heat capacity change information is the change in the volume component of the heating element under the change in the pore opening and closing; in other embodiments, other methods can also be used to determine, which are not limited here.

[0078] In specific implementation, the dynamic thermal response of the heating element under the change of pore opening and closing degree can be determined according to all temperature changes and all heat capacity change information. The following method can be used for this purpose, namely: obtaining the steady-state convective heat transfer coefficient of the heating element through the electronic cigarette material manual, wherein the steady-state convective heat transfer coefficient is a parameter value representing the heat transfer efficiency between the airflow and the surface of the heating element; selecting a pore opening and closing degree as the selected opening and closing degree, adding the selected opening and closing degree to the preset opening and closing frequency, multiplying the added value by the steady-state convective heat transfer coefficient to obtain a first value, dividing the cross-sectional area in the heat capacity change information corresponding to the selected pore opening and closing degree by the temperature change corresponding to the selected opening and closing degree, multiplying the divided value by the first value, and using the multiplied value as the lateral heat dissipation index of the selected pore opening and closing degree, wherein the lateral heat dissipation index is the parameter value of the heat dissipation degree of the heating element perpendicular to the heat transfer direction under the influence of the pore opening and closing degree; the heat capacity change information corresponding to the selected pore opening and closing degree is multiplied by the first value, and the multiplied value is used as the lateral heat dissipation index of the selected pore opening and closing degree.

[0079] It should be noted that the airflow step excitation of the heating element in the electronic cigarette based on the opening and closing range of the electronic cigarette pores and the cold end boundary in the present application, namely: multiple opening and closing degrees of the pores are determined based on the opening and closing range of the electronic cigarette pores; the step response information of the heating element in the process of heating up to the cold end boundary under the change of airflow is determined according to all the opening and closing degrees of the pores and the preset opening and closing frequency; the airflow step excitation refers to the sudden airflow change formed by the change of the pore opening and closing degree to simulate the emergency situation of the electronic cigarette in actual work, so as to obtain the response data in this situation; the dynamic thermal response is the response of the electronic cigarette to the temperature change and the rapid transfer of heat between the heating element and the airflow under the change of the pore opening and closing degree when the temperature is controlled, which is used to describe the ability of the electronic cigarette to respond quickly under the condition of rapid changes in the external environment when the temperature is controlled.

[0080] In some embodiments, determining the heat exchange fluctuation of the heating element during the heating process according to the dynamic thermal response and the temperature gradient of the heating element in the heating state can be achieved by the following steps:

[0090] Next, in step 1032, the external environment temperature of the electronic cigarette is obtained;

[0091] Then, in step 1033, the heat loss control value of the heating element in the electronic cigarette is determined according to the external environment temperature of the electronic cigarette and the thermal expansion transition amount;

[0092] Thus, in step 1034, the heat loss of the heating element during the heating process is determined;

[0093] Finally, in step 1035, the thermal feedback information of the heating element in the electronic cigarette is determined according to the heat loss control value and the heat loss.

[0094] In specific implementation, determining the thermal expansion transition amount of the volume change of the heating element under the thermal effect according to the hot end boundary and the current expansion volume of the heating element can be achieved in the following manner, namely: subtracting the hot end boundary from the real-time temperature of the heating element, and using the subtracted value as the hot end offset of the heating element, wherein the hot end offset is a parameter value indicating the degree of difference between the temperature of the heating element and the hot end boundary during the heating process; performing a logarithmic operation with a base of 2 on the hot end offset, multiplying the value obtained by the logarithmic operation by the current expansion volume, and using the multiplied value as the thermal expansion transition amount of the heating element; wherein the thermal expansion transition amount refers to the change amount of the sudden volume expansion of the heating element under the thermal effect; obtaining the external temperature of the electronic cigarette The boundary environment temperature can be realized in the following manner, namely: obtaining the external environment temperature of the electronic cigarette by a digital thermometer, wherein the external environment temperature refers to the temperature of the environment in which the electronic cigarette is working; determining the heat loss control value of the heating element in the electronic cigarette according to the external environment temperature of the electronic cigarette and the thermal expansion transition amount can be realized in the following manner, namely: obtaining the specific heat capacity of the electronic cigarette heating element from the electronic cigarette material manual, subtracting the real-time temperature of the heating element from the external environment temperature of the electronic cigarette, multiplying the subtracted value by the thermal expansion transition amount, multiplying the multiplied value by the above-mentioned specific heat capacity to obtain the first value, obtaining the real-time temperature of the heating element by a temperature sensor, subtracting the hot end boundary from the real-time temperature of the heating element, and subtracting the subtracted value by the thermal expansion transition amount. The obtained value is added to the first value, the added value is added to the square value of the current pore opening, and the added value is used as the heat loss control value of the heating element, wherein the heat loss control value is a parameter value for compensating and controlling the heat loss of the heating element; determining the heat loss of the heating element during the heating process can be achieved in the following manner, namely: subtracting the real-time temperature of the heating element from the hot end boundary, multiplying the subtracted value by the steady-state convection heat transfer coefficient, multiplying the multiplied value by the cross-sectional area of ​​the heating element at the current temperature, and using the multiplied value as the heat loss of the heating element during the heating process and reaching a thermal steady state; wherein the heat loss is the heat loss generated by the electronic cigarette during the heating process and reaching a thermal steady state, The heat loss control value is a parameter value for measuring and adjusting heat loss, and the thermal steady state refers to a state in which the internal temperature of the heating element in the electronic cigarette remains stable and the input and output of heat reach a balance when the temperature is raised to the current temperature; determining the thermal feedback information of the heating element in the electronic cigarette according to the heat loss control value and the heat loss can be achieved in the following manner, namely: obtaining the material density and specific heat capacity of the heating element from the electronic cigarette material manual; if the heat loss is less than or equal to the heat loss control value, multiplying the material density of the heating element by the specific heat capacity of the heating element, multiplying the multiplied value by the heat loss, and then performing a logarithm operation with a base of 2 on the square of the multiplied value, and using the logarithm operation value as the thermal feedback information of the heating element in the electronic cigarette;If the heat loss is greater than the heat loss control value, the material density of the heating element is multiplied by the specific heat capacity of the heating element, the multiplied value is multiplied by the heat loss control value, and the square of the multiplied value is logarithmically calculated with a base of 2, and the value obtained by the logarithmic calculation is used as the thermal feedback information of the heating element in the electronic cigarette; in other embodiments, other methods can also be used for determination, which is not limited here. ;

[0095] It should be noted that the thermal feedback information in the present application is information used to regulate the heat changes of the heating element. The thermal feedback information can be used to control the temperature changes of the heating element to ensure that the heating element operates within the expected temperature range. This temperature change is generally due to heat loss affecting the thermal capacity of the heating element and ultimately affecting the temperature of the heating element.

[0096] In step 104, the temperature hysteresis of the electronic cigarette during the heating process is determined by the heat exchange fluctuation and the thermal feedback information, and the heating element in the electronic cigarette is adjusted according to the temperature hysteresis.

[0097] In some embodiments, determining the temperature hysteresis of the electronic cigarette during the heating process through the heat exchange fluctuation and the thermal feedback information can be achieved by the following steps:

[0098] Determining a heat compensation factor of the electronic cigarette according to the heat exchange fluctuation;

[0099] The temperature hysteresis of the electronic cigarette during the heating process is determined according to the thermal compensation factor and the thermal feedback information.

[0100] In specific implementation, determining the thermal compensation factor of the electronic cigarette according to the heat exchange fluctuation can be implemented in the following manner, namely: performing a logarithmic operation on the longitudinal heat capacity wave in the heat exchange fluctuation with a natural number as the base, adding the value obtained by the logarithmic operation to the transverse heat capacity fluctuation in the heat exchange fluctuation, and using the added value as the thermal compensation factor of the electronic cigarette; wherein the thermal compensation factor is a parameter for compensating the influence of the delay of the heat capacity change of the heating element on the electronic cigarette; determining the temperature hysteresis of the electronic cigarette in the heating process according to the thermal compensation factor and the thermal feedback information can be implemented in the following manner, namely: multiplying the thermal compensation factor by the square value of the thermal feedback information, performing a logarithmic operation on the value obtained by the multiplication with a natural number as the base, and using the value obtained by the logarithmic operation as the temperature hysteresis of the electronic cigarette in the heating process; in other embodiments, other methods can also be used for determination, which are not limited here.

[0101] It should be noted that the temperature hysteresis in the present application is a parameter indicating the degree of hysteresis of the electronic cigarette during the heating process, and is used to measure the response hysteresis of the electronic cigarette to temperature changes when performing temperature control. The heating strategy of the electronic cigarette can be adjusted through the temperature hysteresis to ensure that the temperature control is more accurate and stable; when the temperature hysteresis is larger, the temperature adjustment can be accelerated to reduce the temperature response delay when the electronic cigarette performs temperature control; when the temperature hysteresis is smaller, the temperature adjustment can be slowed down to avoid excessive temperature overshoot, which will not be elaborated here.

[0102] In some embodiments, adjusting the heating element in the electronic cigarette according to the temperature hysteresis can be achieved by the following steps:

[0103] Determine the temperature hysteresis threshold for temperature control of the electronic cigarette;

[0104] comparing the temperature hysteresis amount with the temperature hysteresis threshold;

[0105] If the temperature hysteresis is greater than or equal to the temperature hysteresis threshold, increasing the air hole opening and closing degree and reducing the heat capacity of the heating element;

[0106] If the temperature hysteresis is less than the temperature hysteresis threshold, the air hole opening degree is reduced and the heat capacity of the heating element is increased.

[0107] It should be noted that the temperature hysteresis threshold described in the present application can be set accordingly according to the specific requirements of the temperature control of the electronic cigarette. If the temperature control of the electronic cigarette needs to have a faster response capability, the temperature hysteresis threshold can be set in a high range; if the temperature control of the electronic cigarette requires very high temperature control accuracy, the temperature hysteresis threshold can be set in a low range; in other embodiments, for example, when external interference is enhanced, the temperature hysteresis threshold can be set in a low range, thereby improving the feasibility of the system temperature control strategy; that is: if the temperature control of the electronic cigarette requires maintaining the temperature at 200°C during the smoking process, and requires very high temperature control accuracy, the temperature hysteresis threshold is set to 1°C to ensure that the temperature is maintained between 199°C and 201°C, thereby improving the user experience and safety.
