Description

[Technical Field]

[0001] This application relates to the technology of heating control for heating non-combustible appliances, and more particularly to a heating control method, apparatus, control unit, and heating non-combustible appliance for heating non-combustible appliances. [Background technology]

[0002] After the non-combustible heating device begins heating, the heating element can heat and calcine the aerosol-generating substrate for the user to use for suction. However, there is a problem with accidentally starting the device in some situations. For example, if no aerosol-generating substrate is inserted into the device, an external force may accidentally touch the device's start button, causing the device to dry-heat, which not only consumes power but also poses a security risk. [Overview of the Initiative] [Problems that the invention aims to solve]

[0003] In view of this, the embodiments of the present invention provide a heating control method, apparatus, control unit, and heating non-combustible appliance for which heating can be automatically turned off if the appliance is accidentally started, thereby reducing power consumption and mitigating security risks. [Means for solving the problem]

[0004] A first embodiment of the present invention provides a heating control method for a heating non-combustion appliance. After the heating non-combustion device starts heating, the actual temperature rise parameter of the heating element of the heating non-combustion device is detected within a predetermined time period. In fact, based on the heating parameters, it is determined whether or not an aerosol-generating substrate is inserted into the non-combustible heating device, and This includes turning off the heating of a non-combustible heating device if no aerosol-generating substrate is inserted into the non-combustible heating device.

[0005] In the technical solution of the embodiment of the present invention, after the heating non-combustion appliance starts heating, the actual temperature rise parameters of the heating element within a predetermined time period are detected. The temperature rise parameters under conditions in which the aerosol-generating substrate is inserted into the heating element are clearly distinguishable from the temperature rise parameters under conditions in which the aerosol-generating substrate is not inserted. For example, the temperature rise rate under conditions in which the aerosol-generating substrate is inserted into the heating element is clearly lower than the temperature rise rate under conditions in which the aerosol-generating substrate is not inserted. Therefore, it is possible to determine whether or not the appliance currently has an aerosol-generating substrate inserted based on the appliance's current actual temperature rise parameters. If it is determined that the appliance does not have an aerosol-generating substrate inserted, it indicates that the appliance is currently running incorrectly. In this case, the heating of the appliance is turned off to reduce power consumption and security risks.

[0006] In one embodiment of the present invention, determining whether or not an aerosol-generating substrate is inserted into a heating non-combustion device based on actual heating parameters is: The system retrieves pre-stored reference temperature rise parameters, where the reference temperature rise parameters include the temperature rise parameters of the heating element within a predetermined time period under the conditions that the heating non-combustible appliance is in a predetermined electrical state and an aerosol-generating substrate is inserted, and / or the temperature rise parameters of the heating element within a predetermined time period under the conditions that the heating non-combustible appliance is in a predetermined electrical state and an aerosol-generating substrate is not inserted, and This includes determining whether or not an aerosol-generating substrate is inserted into a non-combustible heating device based on a comparison between the actual heating parameters and the reference heating parameters.

Based on the comparison result of the actual heating parameter and the reference heating parameter, it is determined whether or not an aerosol-generating substrate is inserted in the heating non-combustible appliance. This includes determining that if the actual heating rate is greater than the first heating rate, then no aerosol-generating substrate has been inserted into the non-combustible heating device.

[0008] In one embodiment of the present invention, the actual temperature rise parameter further includes the actual total energy generated by the heating element within a predetermined time period, and the reference temperature rise parameter further includes a first total energy generated by the heating element within a predetermined time period under the conditions that the heating non-combustible appliance is in the highest electrical state and an aerosol-generating substrate is inserted, and a second total energy generated by the heating element within a predetermined time period under the conditions that the heating non-combustible appliance is in the lowest electrical state that allows it to be started and an aerosol-generating substrate is inserted, and determining whether or not an aerosol-generating substrate is inserted in the heating non-combustible appliance is based on a comparison result between the actual temperature rise parameter and the reference temperature rise parameter. The further includes determining that no aerosol-generating substrate has been inserted into the heating non-combustion device if the actual heating rate is less than or equal to the first heating rate, and the actual total energy is not between the first total energy and the second total energy.

Based on the comparison result of the actual heating parameter and the reference heating parameter, it is determined whether or not an aerosol-generating substrate is inserted into the heating non-combustible appliance. This includes determining that an aerosol-generating substrate has been inserted into the heating non-combustion device if the actual heating rate is lower than the second heating rate.

[0010] In one embodiment of the present invention, the reference temperature rise parameter includes a first temperature rise parameter within a predetermined time period of the heating element under the condition that the heating non-combustible appliance is in its current electrical state and an aerosol-generating substrate is inserted, and a second temperature rise parameter within a predetermined time period of the heating element under the condition that the heating non-combustible appliance is in its current electrical state and an aerosol-generating substrate is not inserted, and determining whether or not an aerosol-generating substrate is inserted in the heating non-combustible appliance is based on the result of comparing the actual temperature rise parameter with the reference temperature rise parameter. Calculate the first difference between the actual heating parameter and the first heating parameter, and calculate the second difference between the actual heating parameter and the second heating parameter, and This includes determining that if the first difference is greater than the second difference, then no aerosol-generating substrate has been inserted into the heating non-combustion device.

[0011] In one embodiment of the present invention, the predetermined time period is within the preheating and temperature rise phase of the heating element.

Modes for Carrying Out the Invention

[0018] In the following description, specific details such as particular system configurations and technologies are proposed for illustrative purposes, not limitation, to fully understand the embodiments of the present application. However, it will be clear to those skilled in the art that the present application can be realized in other embodiments without these specific details. In other cases, detailed descriptions of known systems, apparatus, circuits, and methods are omitted so as not to hinder the description of the present application. Furthermore, in the description of the present specification and the attached claims, terms such as "first," "second," "third," etc., are merely for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0019] In scenarios where non-combustible heating appliances are used, there is a problem of accidentally activating the appliance. For example, if a user places the appliance in their backpack, they may accidentally touch the appliance's activation button through the backpack. In this case, since the appliance does not contain an aerosol-generating substrate, a dry-boil phenomenon occurs, which not only consumes power but also poses a security risk.

[0020] To address this problem, the embodiments of the present application provide a heating control method, apparatus, control unit, and heating non-combustible device for a heating non-combustible device that can reduce power consumption and security risks by determining whether or not an aerosol-generating substrate is currently inserted into the device based on the heating parameters of the heating element, identifying whether or not it is currently activated by mistake, and turning off the heating of the device if it is activated by mistake. For more specific technical realization details of the embodiments of the present application, please refer to the following embodiments.

[0021] Figure 1 is a schematic diagram of a heating non-combustible device according to an embodiment of the present invention. The heating non-combustible device shown in Figure 1 includes a control unit, a heating element, and a battery module, the control unit being electrically connected to the heating element and the battery module, respectively. The control unit is used to control the temperature of the heating element, which can be heated up by the control unit to calcine the aerosol-generating substrate, and the battery module is used to supply electrical energy to the control unit and the heating element.

[0022] The implementing body of each embodiment of the method of this application is a control unit provided within a heating non-combustible appliance, which may be a device such as a main control chip of the heating non-combustible appliance, and it should be understood that the embodiments of this application do not limit the specific type of said control unit in any way.

[0023] Figure 2 shows a heating control method for a non-combustible heating device according to an embodiment of the present invention. It includes the following:

[0024] Step 201: After the heating non-combustion appliance starts heating, the actual temperature rise parameters of the heating element of the heating non-combustion appliance within a predetermined time period are detected.

[0025] When the start button of a non-combustible heating appliance is pressed or accidentally touched by the user, the appliance begins heating and controls the heating element according to a stored standard temperature curve. After the appliance starts, it first enters a preheating phase, controlling the heating element to rise from the ambient temperature to a set target temperature using a full-power output method. If the difference between the actual temperature of the heating element and the target temperature does not exceed a certain threshold (e.g., 30°C), it invokes a PID module to perform PID control on the heating element temperature, outputting signals with different PWM duty cycles to adjust the appliance's output power and gradually stabilize the actual temperature of the heating element to the target temperature.

[0026] After the device is activated and has been heating for a certain period of time, the actual temperature rise parameters of the heating element can be detected within a predetermined time period. Here, the predetermined time period may be any of the temperature rise time periods included in the entire heating process of the heating element, and its specific length is not limited; for example, it may be 2 seconds or 3 seconds. As an example, the predetermined time period can be located within the preheating stage of the heating element, and considering that the temperature rise trend of the heating element in the preheating stage is relatively stable, selecting the predetermined time period from within the preheating stage can improve the accuracy of the actual temperature rise parameters obtained by detection. For example, the heating element enters the preheating stage after starting to heat, and the 0-3 second mark of heating can be selected as the predetermined time period, that is, the actual temperature rise parameters of the heating element within the 0-3 second mark of heating can be detected.

[0027] The actual heating parameters of the heating element within the predetermined time period may include the actual heating rate, the actual heating temperature, and the actual total energy generated. These heating parameters can all be calculated and obtained based on the actual temperature of the heating element at each point in time within the predetermined time period. The actual temperature of the heating element at each point in time can be obtained by calculating the resistance value of the heating element. Specifically, after the appliance starts heating, the resistance value calculation function of the heating element is called at a constant frequency (e.g., 10 times / second) to calculate the current actual resistance value R2 of the heating element, as well as the initial resistance value R1 and temperature coefficient of resistance TCR stored in the appliance, and the current ambient temperature T 室温 Obtain parameters such as, and then use the formula T 現在 =((R2-R1) / (R1*TCR))+T 室温 The actual temperature T of the heating element at the current time 現在 It can be calculated and obtained.

[0028] Assuming that the predetermined time period is from 0 to 3 seconds of heating, and that the actual temperature of the heating element at 0 seconds is T0 and the actual temperature at 3 seconds is T3, the actual heating rate can be obtained by calculating the heating slope. For example, (T3-T0) / 3 can be calculated to obtain the actual heating rate K. Furthermore, considering that the heating trend of the heating element is nonlinear, that is, that the heating slope changes at each point in time, the predetermined time period can be divided into multiple minute time periods, the corresponding heating slope can be calculated for each minute time period, and finally the average value of the heating slopes of all minute time periods can be calculated as the actual heating rate. This can improve the accuracy of the obtained actual heating rate to some extent. The actual heating temperature is the actual temperature of the heating element corresponding to both ends of the predetermined time period, for example, the actual heating temperature T 昇温 This can be calculated based on =T3-T0. The actual total energy generated by the heat source within the predetermined time period is given by the energy calculation empirical formula P=(T2-T1) 2 This can be calculated based on ×Δt, where T2 represents the actual temperature of the heat source at the present time, T1 represents the actual temperature of the heat source at the previous time, and Δt represents the time difference between the present time and the previous time. If there are multiple Δt intervals within the predetermined time period, the corresponding energy value is calculated for each Δt interval according to the energy calculation empirical formula, and finally, the total actual energy generated by the heat source within the predetermined time period can be obtained by accumulating the energy values ​​corresponding to each of the intervals.

[0029] Step 202: Based on the actual heating parameters, determine whether or not an aerosol-generating substrate is inserted into the heating non-combustion device.

[0030] After obtaining the actual temperature rise parameters of the heating element within a predetermined time period, it is possible to determine whether or not an aerosol-generating substrate is inserted into the non-combustible heating device based on these actual temperature rise parameters. The principle of this operation is that the temperature rise parameters of the heating element under conditions in which an aerosol-generating substrate is inserted are clearly distinguishable from those under conditions in which an aerosol-generating substrate is not inserted, and by comparing the actual temperature rise parameters with the temperature rise parameters of the heating element under different known conditions, it is possible to determine whether or not an aerosol-generating substrate is currently inserted into the device. Several implementations of identifying whether or not an aerosol-generating substrate is inserted into the device based on the actual temperature rise parameters will be described in detail below.

[0031] In one embodiment of the present invention, determining whether or not an aerosol-generating substrate is inserted into a heating non-combustion device based on actual heating parameters is: (1) Obtain a pre-stored reference temperature rise parameter, where the reference temperature rise parameter includes the temperature rise parameter of the heating element within a predetermined time period under the conditions that the heating non-combustible appliance is in a predetermined electrical state and an aerosol-generating substrate is inserted, and / or the temperature rise parameter of the heating element within a predetermined time period under the conditions that the heating non-combustible appliance is in a predetermined electrical state and an aerosol-generating substrate is not inserted, and (2) This includes determining whether or not an aerosol-generating substrate is inserted into the heating non-combustion device based on the results of comparing the actual heating parameters with the reference heating parameters.

[0032] Generally, the heating parameters of a heating element are related to factors such as the battery charge of the device and whether or not an aerosol-generating substrate is inserted into the device. Specifically, there is a positive correlation between the heating parameters of a heating element and the battery charge; that is, the higher the battery charge, the greater the heating parameters such as the heating rate of the heating element, and the lower the battery charge, the smaller the heating parameters such as the heating rate of the heating element. When an aerosol-generating substrate is inserted into the device, some of the heat is absorbed by both the outer wall of the device and the aerosol-generating substrate during the heating operation of the heating element. When an aerosol-generating substrate is not inserted into the device, some of the heat is absorbed only by the outer wall of the device during the heating operation of the heating element. Therefore, for the same battery charge, the heating parameters of a heating element in a device without an aerosol-generating substrate are greater than those of a heating element in a device with an aerosol-generating substrate. In actual operation, the apparatus can pre-calculate reference heating parameters such as the heating rate of the heating element within a predetermined time period, the heating temperature, or the total energy generated, under different conditions such as various electrical state (e.g., maximum electrical state, minimum electrical state for starting the apparatus, 70% electrical state, 50% electrical state, 30% electrical state, etc.), insertion of an aerosol-generating substrate, and non-insertion of an aerosol-generating substrate, depending on the experimental test method. These reference heating parameters can be stored in a memory device such as the apparatus's register Flash.

[0033] After obtaining the above-mentioned reference temperature rise parameter, the control unit of the device can determine whether the characteristics of the actual temperature rise parameter are closer to the temperature rise parameter under conditions in which an aerosol-generating substrate is inserted, or closer to the temperature rise parameter under conditions in which an aerosol-generating substrate is not inserted, and can then determine whether or not an aerosol-generating substrate is currently inserted in the device. The obtained reference temperature rise parameter for comparison may include only the temperature rise parameter corresponding to the device under conditions in which an aerosol-generating substrate is inserted at a certain specified electrical state (e.g., the highest electrical state or the lowest electrical state), or only the temperature rise parameter corresponding to the device under conditions in which an aerosol-generating substrate is not inserted at a certain specified electrical state, or it may include both the temperature rise parameter corresponding to the device under conditions in which an aerosol-generating substrate is inserted at a certain specified electrical state and the temperature rise parameter corresponding to the device under conditions in which an aerosol-generating substrate is not inserted at a certain specified electrical state, or it may include both the temperature rise parameter corresponding to the device under conditions in which an aerosol-generating substrate is not inserted at a certain specified electrical state, or it may include both the temperature rise parameter corresponding to the device under multiple different electrical state conditions, and the embodiments of this application are not limited in any way. Generally, the more reference heating parameters obtained for comparison, the more accurate it is to determine whether or not an aerosol-generating substrate has been inserted into the instrument. Below, we will describe several specific implementations of determining whether or not an aerosol-generating substrate has been inserted into the instrument based on the comparison results of heating parameters.

[0034] In one embodiment of the present invention, the actual heating parameter includes the actual heating rate of the heating element within a predetermined time period, and the reference heating parameter includes a first heating rate of the heating element within a predetermined time period under conditions where the heating non-combustible appliance is in a state of maximum electrical charge and an aerosol-generating substrate is inserted. Based on the comparison result between the actual heating parameter and the reference heating parameter, it is determined whether or not an aerosol-generating substrate is inserted into the heating non-combustible appliance.

[0035] If the actual heating rate is greater than the first heating rate, it is determined that no aerosol-generating substrate has been inserted into the non-combustible heating device.

[0036] Assuming that the acquired actual heating parameter includes the actual heating rate K of the heating element within a predetermined time period, and the acquired reference heating parameter includes the first heating rate K1 of the heating element within a predetermined time period under conditions where the device is in the maximum charge state and an aerosol-generating substrate is inserted, we compare the magnitude of the actual heating rate K and the first heating rate K1. Referring to the above analysis, the higher the battery charge, the greater the heating rate of the heating element, and since the first heating rate K1 corresponds to the maximum charge state, the first heating rate K1 represents the maximum heating rate of the heating element within a predetermined time period when an aerosol-generating substrate is inserted. Specifically, when the current battery charge of the device is in the maximum charge state and an aerosol-generating substrate is inserted in the device, the detected actual heating rate K is approximately equal to the first heating rate K1, and when the current battery charge of the device is not in the maximum charge state and an aerosol-generating substrate is inserted in the device, the detected actual heating rate K is smaller than the first heating rate K1. Therefore, if the detected actual heating rate K is greater than the first heating rate K1, it indicates that the actual heating rate K exceeds the maximum heating rate of the heating element within a predetermined time period when an aerosol-generating substrate is inserted. Thus, it can be determined that no aerosol-generating substrate is inserted into the device, and the heating rate of the heating element will be higher when no aerosol-generating substrate is inserted.

[0037] Conversely, if the detected actual heating rate K is less than or equal to the first heating rate K1, it indicates that an aerosol-generating substrate may currently be inserted into the device. One way to handle this is to directly determine that an aerosol-generating substrate is currently inserted into the device. However, considering that the detected actual heating rate K may be less than or equal to the first heating rate K1, for example, if a foreign object (such as a metal rod or ceramic rod) is inserted into the device, or if the device is in a low-power state and no aerosol-generating substrate is inserted, immediately determining that an aerosol-generating substrate is currently inserted into the device when K ≤ K1 is detected is likely to lead to a false positive. To address this problem, after detecting that K ≤ K1, a further determination can be made by combining the actual total energy generated by the heating element within a predetermined time period. This reduces false positives and improves the accuracy of identifying whether or not an aerosol-generating substrate is inserted into the device. A detailed explanation will follow later.

[0038] In one embodiment of the present invention, the actual heating parameter further includes the actual total energy generated by the heating element within a predetermined time period, the reference heating parameter further includes a first total energy generated by the heating element within a predetermined time period under conditions where the heating non-combustible appliance is in the highest electrical state and an aerosol-generating substrate is inserted, and a second total energy generated by the heating element within a predetermined time period under conditions where the heating non-combustible appliance is in the lowest electrical state capable of starting and an aerosol-generating substrate is inserted, and determining whether or not an aerosol-generating substrate has been inserted into the heating non-combustible appliance based on a comparison of the actual heating parameter and the reference heating parameter further includes determining that an aerosol-generating substrate has not been inserted into the heating non-combustible appliance if the actual heating rate is less than or equal to the first heating rate and the actual total energy is not between the first total energy and the second total energy.

[0039] If the detected actual heating rate K is less than or equal to the first heating rate K1, the actual total energy P generated by the heating element within a predetermined time period is obtained. Under the conditions that the heating non-combustible appliance is in its maximum electrical state and an aerosol-generating substrate is inserted, the first total energy P1 generated by the heating element within a predetermined time period is obtained. Under the conditions that the heating non-combustible appliance is in its minimum electrical state and an aerosol-generating substrate is inserted, the second total energy P2 generated by the heating element within a predetermined time period is obtained. Here, the first total energy P1 represents the maximum total energy generated by the heating element within a predetermined time period when an aerosol-generating substrate is inserted, and the second total energy P2 represents the minimum total energy generated by the heating element within a predetermined time period when an aerosol-generating substrate is inserted. Therefore, [P2, P1] represents the normal total energy range generated by the heating element within a predetermined time period when an aerosol-generating substrate is inserted. The system determines whether the actual total energy P is between the first total energy P1 and the second total energy P2, that is, whether the actual total energy P is in the energy interval [P2, P1]. If the actual total energy P is in the energy interval [P2, P1], it indicates that the actual total energy generated by the heating element is within the normal total energy range when an aerosol-generating substrate is inserted into the device, and in this case, it can be determined that an aerosol-generating substrate has now been inserted into the device. If the actual total energy P is outside the energy interval [P2, P1], it indicates that the actual total energy generated by the heating element exceeds the normal total energy range when an aerosol-generating substrate is inserted into the device, and therefore, it is determined that an aerosol-generating substrate has not been inserted into the device.In special cases such as when foreign objects are inserted into the device, or when the device is in a low power state and no aerosol-generating substrate is inserted, the heating curve of the heating element is clearly distinguishable from the heating curve in the normal case where an aerosol-generating substrate is inserted into the device. Since the actual total energy calculated in these special cases may exceed the normal total energy range [P2, P1], by adding a further determination of the actual total energy, that is, when it is determined that the actual total energy P is within the energy interval [P2, P1], it is only then determined that an aerosol-generating substrate is currently inserted into the device, and misjudgments can be reduced to a certain extent, improving the accuracy of identifying whether an aerosol-generating substrate is inserted into the device.

[0040] As an example, FIG. 3 is a schematic diagram of the principle for identifying whether an aerosol-generating substrate is inserted into a device based on the heating rate and the total energy generated by the heating element according to an embodiment of the present application. The horizontal axis of FIG. 3 represents time, the vertical axis represents the temperature of the heating element, C1 represents the heating curve of the heating element under the condition that the heat-not-burn device is in the maximum power state and an aerosol-generating substrate is inserted, C2 represents the heating curve of the heating element under the condition that the heat-not-burn device is in the minimum power state where it can be activated and an aerosol-generating substrate is inserted, K1 represents the heating rate of the heating element in the 0-3 second time period under the condition that the heat-not-burn device is in the maximum power state and an aerosol-generating substrate is inserted, P1 represents the total energy generated by the heating element within the 0-3 second time period under the condition that the heat-not-burn device is in the maximum power state and an aerosol-generating substrate is inserted, and P2 represents the total energy generated by the heating element within the 0-3 second time period under the condition that the heat-not-burn device is in the minimum power state where it can be activated and an aerosol-generating substrate is inserted. Here, K1 is obtained by calculating the heating slope at the 3rd second of curve C1, P1 and P2 are obtained by calculating the energy integral, P1 is the area of the shaded part enclosed by curve C1 and the two dashed lines in FIG. 3, P2 is the area of the shaded part enclosed by curve C2 and the two dashed lines in FIG. 3, and P1 and P2 are both in the formula Σ(T 現在 -T 前の時刻 ) 2Calculated based on ×Δt, T 現在 This indicates the actual temperature of the heating element at the current time, T 前の時刻 Δt indicates the actual temperature of the heating element at the previous time, and Δt indicates the time difference between the two time points. The calculated K1, P1, and P2 are stored in the instrument's register Flash. After detecting the actual heating rate K and the actual total energy P generated within the 0-3 second time period of the heating element, a comparison of the parameters is performed. If K > K1, it can be directly determined that no aerosol-generating substrate has been inserted into the instrument. If K ≤ K1, it is further determined whether P is within [P2, P1]. If P is within [P2, P1], it is determined that an aerosol-generating substrate has been inserted into the instrument; otherwise, it is determined that no aerosol-generating substrate has been inserted into the instrument.

[0041] In one embodiment of the present invention, the actual heating parameter includes the actual heating rate of the heating element within a predetermined time period, and the reference heating parameter includes a second heating rate of the heating element within a predetermined time period under conditions where the heating non-combustible appliance is in the minimum electrical state at which it can be started and no aerosol-generating substrate has been inserted. Determining whether or not an aerosol-generating substrate has been inserted into the heating non-combustible appliance based on a comparison between the actual heating parameter and the reference heating parameter includes determining that an aerosol-generating substrate has been inserted into the heating non-combustible appliance if the actual heating rate is less than the second heating rate.

[0042] Assuming that the acquired actual heating parameter includes the actual heating rate K of the heating element within a predetermined time period, and the acquired reference heating parameter includes the second heating rate K2 of the heating element within a predetermined time period under conditions where the device is in the minimum power state for activation and no aerosol-generating substrate is inserted, the magnitudes of the actual heating rate K and the second heating rate K2 are compared. Referring to the above analysis, the lower the battery charge, the lower the heating rate of the heating element, and since the second heating rate K2 corresponds to the minimum power state for activation, the second heating rate K2 represents the minimum heating rate of the heating element within a predetermined time period when no aerosol-generating substrate is inserted. Specifically, when the current battery charge of the device is in the minimum power state and no aerosol-generating substrate is inserted in the device, the detected actual heating rate K is approximately equal to the second heating rate K2, and when the current battery charge of the device is not in the minimum power state and no aerosol-generating substrate is inserted in the device, the detected actual heating rate K is greater than the second heating rate K2. Therefore, if the detected actual heating rate K is smaller than the second heating rate K2, it indicates that the actual heating rate K is smaller than the minimum heating rate of the heating element within a predetermined time period when no aerosol-generating substrate is inserted. This allows us to determine that an aerosol-generating substrate is currently inserted in the device, and the heating rate of the heating element decreases when an aerosol-generating substrate is inserted. Conversely, if the detected actual heating rate K is greater than or equal to the second heating rate K2, it is temporarily impossible to determine whether or not an aerosol-generating substrate is inserted in the device. In this case, further determination can be made by combining the first heating rate K1 and the normal total energy range [P2, P1] described above.

[0043] In one embodiment of the present invention, the reference temperature rise parameter includes a first temperature rise parameter within a predetermined time period of the heating element under the condition that the heating non-combustible appliance is in its current electrical state and an aerosol-generating substrate is inserted, and a second temperature rise parameter within a predetermined time period of the heating element under the condition that the heating non-combustible appliance is in its current electrical state and an aerosol-generating substrate is not inserted, and the determination of whether or not an aerosol-generating substrate is inserted into the heating non-combustible appliance is made based on the result of comparing the actual temperature rise parameter with the reference temperature rise parameter. (1) Calculate the first difference between the actual heating parameter and the first heating parameter, and calculate the second difference between the actual heating parameter and the second heating parameter, and (2) If the first difference is greater than the second difference, it is determined that no aerosol-generating substrate has been inserted into the heating non-combustion device.

[0044] The device can pre-calculate and store the heating parameters for a predetermined time period of a heating element under various different electrical conditions and with an aerosol-generating substrate inserted, and the heating parameters for a predetermined time period of a heating element under various different electrical conditions and without an aerosol-generating substrate inserted. For example, the heating parameters for a predetermined time period of a heating element under conditions of 5% electrical charge with an aerosol-generating substrate inserted, the heating parameters for a predetermined time period of a heating element under conditions of 5% electrical charge without an aerosol-generating substrate inserted, the heating parameters for a predetermined time period of a heating element under conditions of 50% electrical charge with an aerosol-generating substrate inserted, the heating parameters for a predetermined time period of a heating element under conditions of 75% electrical charge with an aerosol-generating substrate inserted, the heating parameters for a predetermined time period of a heating element under conditions of 75% electrical charge without an aerosol-generating substrate inserted, and so on.

[0045] After obtaining the actual heating parameter X of the heating element within a predetermined time period (specifically, this may be the actual heating rate, actual heating temperature, etc.), the current electrical state of the appliance is determined, and the first heating parameter X1 of the heating element within the predetermined time period is searched under the conditions that the appliance is in the current electrical state and an aerosol-generating substrate is inserted, and the second heating parameter X2 of the heating element within the predetermined time period is searched under the conditions that the appliance is in the current electrical state and an aerosol-generating substrate is not inserted. Next, the first difference Y1 = |X - X1| between the actual heating parameter X and the first heating parameter X1, and the second difference Y2 = |X - X2| between the actual heating parameter X and the second heating parameter X2 are calculated. If Y1 is greater than Y2, it indicates that the actual heating parameter X is closer to the heating parameter without an aerosol-generating substrate, thus determining that no aerosol-generating substrate is inserted into the non-combustible heating appliance. If Y1 is less than Y2, it indicates that the actual heating parameter X is closer to the heating parameter with an aerosol-generating substrate, thus determining that an aerosol-generating substrate is inserted into the non-combustible heating appliance. This method of operation can similarly determine whether or not an aerosol-generating substrate is currently inserted into the appliance by finding a suitable reference heating parameter based on the current electrical state of the appliance and comparing whether the actual heating parameter is closer to the heating parameter when an aerosol-generating substrate is inserted or when it is not.

[0046] Step 203: If no aerosol-generating substrate is inserted into the heating non-combustion device, turn off the heating of the heating non-combustion device.

[0047] If it is determined that no aerosol-generating substrate has been inserted into the non-combustible heating device, this would mean the device is being started incorrectly. Therefore, turning off the heating of the device reduces power consumption and lowers security risks. Conversely, if it is determined that an aerosol-generating substrate has been inserted into the non-combustible heating device, this indicates that the device is being used normally, and in this case, the heating element can continue to be controlled according to the standard temperature curve.

[0048] In the technical solution of the embodiment of the present invention, after the heating non-combustion appliance starts heating, the actual temperature rise parameters of the heating element within a predetermined time period are detected. The temperature rise parameters under conditions in which the aerosol-generating substrate is inserted into the heating element are clearly distinguishable from the temperature rise parameters under conditions in which the aerosol-generating substrate is not inserted. For example, the temperature rise rate under conditions in which the aerosol-generating substrate is inserted into the heating element is clearly lower than the temperature rise rate under conditions in which the aerosol-generating substrate is not inserted. Therefore, it is possible to determine whether or not the appliance currently has an aerosol-generating substrate inserted based on the appliance's current actual temperature rise parameters. If it is determined that the appliance does not have an aerosol-generating substrate inserted, it indicates that the appliance has been started incorrectly. At this time, the heating of the appliance is turned off to reduce power consumption and security risks.

[0049] To facilitate understanding of the heating control method for a non-combustible heating device according to the embodiment of this application, actual application scenarios are listed below.

[0050] Figure 4 is a schematic diagram of the operation flow in an actual application scene of the heating control method for a heating non-combustible device according to an embodiment of the present invention. In the application scene shown in Figure 4, after the heating non-combustible device starts heating, the actual heating rate K of the heating element during the 0-3 second time period is detected, and the actual total energy P generated by the heating element during the 0-3 second time period is detected. Then, it is first determined whether the actual heating rate K is greater than the first heating rate K1, where K1 is the heating rate of the heating element during the 0-3 second time period under conditions where the device is in the maximum electrical state and an aerosol-generating substrate is inserted. If K > K1, it is determined that an aerosol-generating substrate has not been inserted into the smoking device, and in this case, the heating of the device is turned off. If K ≤ K1 The system continues to compare energy values ​​and determines whether the actual total energy P is between the first total energy P1 and the second total energy P2. P1 is the total energy of the heating element during the 0-3 second time period under conditions where the device is in its maximum electrical state and an aerosol-generating substrate is inserted. If P is not between P1 and P2, it is determined that no aerosol-generating substrate is inserted in the smoking device, and the device's heating is turned off. If P is between P1 and P2, it is determined that an aerosol-generating substrate is inserted in the smoking device, and heating can continue according to the standard temperature curve. By installing the system in this way, it is possible to identify whether an aerosol-generating substrate is currently inserted in the device based on the device's heating parameters, and if it is determined that no aerosol-generating substrate is inserted in the device, the device's heating can be automatically turned off, thereby reducing power consumption and security risks.
