Description

Technical Field

[0001] The present application relates to the technical field of temperature control of heat-without-combustion appliances, and in particular to a preheating control method, device, controller and heat-without-combustion appliance of the heat-without-combustion appliance. Background Art

[0002] After the heating-not-burning appliance is started, the heating element will be heated and controlled according to the stored standard temperature curve. The first part of the standard temperature curve belongs to the preheating period. The temperature curve of the preheating period first rises to the highest preheating temperature and maintains it for a certain period of time, then cools down and enters the temperature stabilization stage, maintaining a certain set temperature for insulation until the end of the preheating period.

[0003] The existing standard temperature curve is usually debugged under a normal temperature environment of about 25°C. However, when the user uses a heat-not-burn device under extremely high or low ambient temperatures, the heating element of the device will still be preheated according to the standard temperature curve. Since the ambient temperature will affect the heating rate of the heating element, the energy generated by the heating element when preheating according to the standard temperature curve at different ambient temperatures varies greatly, which can lead to problems such as scalding the mouth when smoking or insufficient preheating energy. Summary of the invention

[0004] In view of this, the embodiments of the present application provide a preheating control method, device, controller and heating non-combustion appliance, which can make the energy generated by preheating the heating element under different ambient temperatures close to the standard energy value, thereby avoiding problems such as scalding the mouth when smoking or insufficient preheating energy.

[0005] A first aspect of an embodiment of the present application provides a preheating control method for a heating-not-burning appliance, comprising:

[0006] When the heating without burning appliance starts preheating and reaches a first time point, detecting a first energy value generated by a heating element of the heating without burning appliance;

[0007] If the first energy value is different from the second energy value generated when the heating element reaches the maximum preheating temperature according to the standard temperature curve, the heating temperature of the heating element during the preheating process from the first time point to the second time point is adjusted so that the actual energy value generated by the heating element during the preheating period is close to the standard energy value;

[0008] Among them, the standard energy value is the energy value generated by the preheating process of the heating element according to the standard temperature curve during the preheating period. The first time point is the time point when the heating element reaches the highest preheating temperature recorded in the standard temperature curve, and the second time point is the time point when the preheating period ends.

[0009] In the technical solution of the embodiment of the present application, it is assumed that the time point when the heating element recorded in the standard temperature curve reaches the highest preheating temperature is the first time point, the time point when the preheating period ends is the second time point, the energy value generated when the heating element reaches the highest preheating temperature according to the standard temperature curve is the second energy value, and the energy value generated by the heating element during the preheating period according to the standard temperature curve is the standard energy value. When the heating-not-burning device starts preheating and reaches the first time point, the first energy value currently generated by the heating element is detected. Due to the influence of the ambient temperature, the time when the heating element actually heats up to the highest preheating temperature may deviate from the first time point, which will cause the first energy value to be different from the second energy value, thereby affecting the energy generated during the entire preheating period. In order to balance the energy deviation, the heating temperature of the preheating process of the heating element from the first time point to the second time point is adjusted, so that the energy generated by the preheating process from the first time point to the second time point can be controlled to offset the deviation between the first energy value and the second energy value, so that the actual energy value generated by the heating element during the entire preheating period is close to the standard energy value. For example, if the ambient temperature is high, the heating element will heat up faster to reach the highest preheating temperature. In this way, when the preheating reaches the first time point, the first energy value generated by the heating element will be greater than the second energy value. At this time, the heating temperature of the preheating process from the first time point to the second time point can be reduced, so that the energy generated by the preheating process from the first time point to the second time point is reduced, and the energy difference is offset. It can be seen that through such a setting, the energy generated by the heating element during preheating at different ambient temperatures can be close to the standard energy value, thereby avoiding problems such as burning the mouth when smoking or insufficient preheating energy.

[0010] In one implementation of the embodiment of the present application, adjusting the heating temperature of the heating element in the preheating process from the first time point to the second time point includes:

[0011] If the first energy value is greater than the second energy value, the heating temperature of the heating element during the preheating process from the first time point to the second time point is reduced;

[0046] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures, technologies, etc. are proposed, so as to thoroughly understand the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details. In other cases, the detailed description of well-known systems, devices, circuits and methods is omitted to prevent unnecessary details from hindering the description of the present application. In addition, in the description of the present application specification and the attached claims, the terms "first", "second", "third" etc. are only used to distinguish the description, and cannot be interpreted as indicating or suggesting relative importance.

[0047] After starting, the heating-not-burning appliance first enters the preheating period, during which the heating element is heated and controlled according to the stored standard temperature curve, thereby realizing the preheating operation of the appliance. However, the standard temperature curve is obtained by debugging under normal temperature. If the heating element is still preheated according to the standard temperature curve under extremely high or low ambient temperature, the energy generated during the preheating process will be significantly different from the standard value, which will lead to problems such as scalding the mouth when smoking or insufficient preheating energy.

[0048] In view of the above problems, the embodiments of the present application provide a preheating control method, device, controller and a heat-not-burn appliance for a heat-not-burn appliance, which can make the energy generated by the preheating of the heating element at different ambient temperatures close to the standard energy value, thereby avoiding problems such as scalding the mouth when smoking or insufficient preheating energy. For more specific technical implementation details of the embodiments of the present application, please refer to the various embodiments described below.

[0049] like Figure 1, which is a schematic diagram of a heating without burning appliance provided in an embodiment of the present application. Figure 1 The heating-not-burning device shown includes a controller, a heating element, and a battery module, wherein the controller is electrically connected to the heating element and the battery module, respectively. The controller can be used to control the temperature of the heating element, and the heating element can be heated up under the control of the controller to bake the aerosol-generating matrix, and the battery module is used to provide electrical energy to the controller and the heating element.

[0050] It should be understood that the executor of each method embodiment of the present application is a controller provided in the heating without burning appliance, for example, it can be a device such as the main control chip of the heating without burning appliance, and the embodiments of the present application do not impose any restrictions on the specific type of the controller.

[0051] See also Figure 2 , shows a preheating control method for a heating-without-combustion appliance provided in an embodiment of the present application, comprising:

[0052] 201. When the heating without burning appliance starts preheating and reaches a first time point, detecting a first energy value generated by a heating element of the heating without burning appliance;

[0053] When the heating-not-burning appliance is started and enters the preheating period, the controller controls the heating of the heating element according to the stored standard temperature curve. The standard temperature curve usually includes two parts: the preheating period and the suction period. The temperature curve of the preheating period can be divided into three stages: the heating stage, the transition stage, and the temperature stabilization stage. When the preheating process begins, it first enters the heating stage, and controls the heating element to heat up from the ambient temperature to the set maximum preheating temperature through full power output, and then enters the transition stage; in the transition stage, the heating element will be controlled to maintain the highest preheating temperature for a certain period of time, and then cool down and enter the temperature stabilization stage; in the temperature stabilization stage, the heating element will be controlled to maintain a certain set temperature for insulation until the end of the preheating period.

[0054] The standard temperature curve is usually debugged and obtained under a normal temperature environment of about 25°C, and stored in the device's register Flash and other storage devices. After the standard temperature curve is given, the time point when the preheating period begins, the time point when the heating element reaches the maximum preheating temperature (that is, the time point when the heating stage ends), the time point when the temperature enters the temperature stabilization stage, and the time point when the preheating period ends are all known. Moreover, when the standard temperature curve is known, the energy value generated by the preheating process of the heating element according to the standard temperature curve during the preheating period can be calculated by integrating the area, as well as the energy value generated when the heating element reaches the maximum preheating temperature according to the standard temperature curve.

[0055] In the description of the embodiments of the present application, the standard energy value is the energy value generated by the process of preheating the heating element according to the standard temperature curve during the preheating period, the second energy value is the energy value generated when the heating element is heated up to the maximum preheating temperature according to the standard temperature curve, the first time point is the time point recorded in the standard temperature curve when the heating element heats up to the maximum preheating temperature, the second time point is the time point when the preheating period ends, and the third time point is the time point recorded in the standard temperature curve when the heating element enters the temperature stabilization stage of the preheating process.

[0056] Regardless of the actual ambient temperature of the device, after startup, the device first controls the heating element according to the standard temperature curve until the time reaches the first time point. At this time, the energy value generated by the heating element is detected and recorded as the first energy value.

[0057] Generally speaking, if the actual ambient temperature is equal to the standard ambient temperature corresponding to the standard temperature curve, the actual temperature curve of the heating element is basically equivalent to the standard temperature curve. In this way, when the first time point is reached, the energy value generated by the heating element is equivalent to the energy value generated when the heating element is heated according to the standard temperature curve to reach the highest preheating temperature, that is, the first energy value is equal to the second energy value.

[0058] If the actual ambient temperature is higher than the standard ambient temperature, the heating element will heat up faster, and the time point when the actual temperature curve reaches the maximum preheating temperature will be advanced. In this way, when the time reaches the first time point, the heating element has actually been maintained at the maximum preheating temperature for a certain period of time. At this time, the energy value generated by the heating element will be greater than the energy value generated when the heating element heats up to the maximum preheating temperature according to the standard temperature curve, that is, the first energy value is greater than the second energy value.

[0059] If the actual ambient temperature is lower than the standard ambient temperature, the heating element will heat up more slowly, and the time point when the actual temperature curve reaches the maximum preheating temperature will be delayed. In this way, when the time reaches the first time point, the heating element has not yet heated up to the maximum preheating temperature. Therefore, the energy value generated by the heating element at this time will be less than the energy value generated when the heating element heats up to the maximum preheating temperature according to the standard temperature curve, that is, the first energy value is less than the second energy value.

[0060] In one implementation of the embodiment of the present application, detecting a first energy value generated by a heating element of a heat-not-burn appliance includes:

[0061] (1) obtaining an actual temperature curve of the heating element from the time point at which the preheating period starts to the first time point;

[0062] (2) Determine the functional expression of the actual temperature curve by curve fitting;

[0063] (3) Calculate the integral value of the function expression from the time point when the preheating period starts to the first time point as the first energy value.

[0064] When detecting and calculating the first energy value, the method of integrating to obtain the area can be used. Specifically, during the preheating process of the appliance, the controller can continuously detect and record the real-time temperature of the heating element, thereby drawing an actual temperature curve. When the time reaches the first time point, the actual temperature curve of the heating element from the time point when the preheating period starts to the first time point can be drawn, and the function expression of the actual temperature curve can be determined by curve fitting. When the starting point and end point of the integration are known, the area of ​​the area enclosed by the actual temperature curve and the coordinate axis can be obtained by calculating the definite integral, thereby obtaining the first energy value. For example, assuming that the time point at the beginning of the preheating period is t0, the first time point is t1, and the function expression of the actual temperature curve is f(t), then the definite integral is calculated The first energy value P1 can be obtained. Similarly, the second energy value can also be pre-calculated in the same way and stored in the register Flash of the device. Assuming that the standard temperature curve is g(t), the definite integral is calculated The second energy value P2 can be obtained.

[0065] In one implementation of the embodiment of the present application, a function expression of the actual temperature curve is determined by curve fitting, including:

[0066] (1) if the actual ambient temperature of the heating-not-burning device is higher than the standard ambient temperature corresponding to the standard temperature curve, then determining a fourth time point at which the heating element reaches the maximum preheating temperature according to the actual temperature curve;

[0067] (2) By means of curve fitting, a first function expression corresponding to a curve segment from a time point at which the preheating period starts to a fourth time point in the actual temperature curve is determined, and a second function expression corresponding to a curve segment from a fourth time point to a first time point in the actual temperature curve is determined.

[0068] If the actual ambient temperature is higher than the standard ambient temperature, the time point when the actual temperature curve heats up to the highest preheating temperature will be advanced, so that when the time reaches the first time point, the heating element has actually been maintained at the highest preheating temperature for a certain length of time. Obviously, the actual temperature curve at this time can be divided into two parts, the first part is the curve that heats up to the highest preheating temperature, and the second part is the curve that is maintained at the highest preheating temperature. In order to obtain a more accurate energy value calculation result, the function expression corresponding to each of the two parts of the curve can be obtained by piecewise fitting, and then the piecewise integral calculation is performed. In the specific operation, first find the time point when the heating element heats up to the highest preheating temperature according to the actual temperature curve, recorded as the fourth time point, and the fourth time point is before the first time point. Then, by means of curve fitting, determine the first function expression corresponding to the curve segment from the time point at the beginning of the preheating period to the fourth time point in the actual temperature curve, and determine the second function expression corresponding to the curve segment from the fourth time point to the first time point in the actual temperature curve. As for the case where the actual ambient temperature is lower than the standard ambient temperature, since the time point when the actual temperature curve rises to the maximum preheating temperature will be delayed, when the time reaches the first time point, the heating element has not yet heated up to the maximum preheating temperature, that is, the actual temperature curve obtained is still a continuously rising curve, so there is no need for segmented fitting.

[0069] Calculating the integral value of the function expression from the time point when the preheating period starts to the first time point as the first energy value includes:

[0070] (1) calculating the integral value of the first function expression from the time point when the preheating period starts to the fourth time point to obtain a first area, and calculating the integral value of the second function expression from the fourth time point to the first time point to obtain a second area;

[0071] (2) Calculate the sum of the first area and the second area as the first energy value.

[0072] After fitting to obtain the first function expression and the second function expression, perform segmented integral calculations, specifically calculate the integral value of the first function expression from the time point at which the preheating period starts to the fourth time point to obtain the first area, and calculate the integral value of the second function expression from the fourth time point to the first time point to obtain the second area, and finally calculate the sum of the first area and the second area to obtain the first energy value. For example, assuming that the time point at which the preheating period starts is t0, the first time point is t1, the fourth time point is tx, the first function expression is f1(t), and the second function expression is f2(t), then the first area Second area The first energy value P1 = S1 + S2. By performing segmented fitting on the actual temperature curve, a more accurate curve function expression can be obtained, thereby obtaining a more accurate energy value calculation result.

[0073] 202. If the first energy value is different from the second energy value, the heating temperature of the heating element in the preheating process from the first time point to the second time point is adjusted so that the actual energy value generated by the heating element during the preheating period is close to the standard energy value.

[0074] After calculating the first energy value, the first energy value is compared with the second energy value. If the first energy value is the same as the second energy value, it means that the actual ambient temperature is close to the standard ambient temperature, and the heating element is preheated basically completely according to the standard temperature curve. At this time, there is no need to adjust the heating temperature of the heating element during the preheating process from the first time point to the second time point (that is, the preheating process after the current time point), and the heating element continues to complete the subsequent preheating process according to the standard temperature curve, so that the actual energy value generated by the heating element during the entire preheating period is basically equivalent to the standard energy value.

[0075] If the first energy value is different from the second energy value, in order to balance the energy deviation, starting from the first time point, the heating temperature of the preheating process of the heating element from the first time point to the second time point is adjusted. This can control the amount of energy generated by the preheating process from the first time point to the second time point to offset the deviation between the first energy value and the second energy value, so that the actual energy value generated by the heating element during the entire preheating period is close to the standard energy value.

[0076] In one implementation of the embodiment of the present application, adjusting the heating temperature of the heating element in the preheating process from the first time point to the second time point includes:

[0077] (1) if the first energy value is greater than the second energy value, reducing the heating temperature of the heating element during the preheating process from the first time point to the second time point;

[0078] (2) If the first energy value is less than the second energy value, the heating temperature of the heating element in the preheating process from the first time point to the second time point is increased.

[0079] If the actual ambient temperature is higher than the standard ambient temperature, the calculated first energy value will be greater than the second energy value, which means that the energy value generated in the heating stage of the preheating period is too high, and it is necessary to reduce the corresponding energy value in the subsequent stages of the preheating period (the transition stage and the temperature stabilization stage, that is, the time period from the first time point to the second time point). Specifically, the energy value can be reduced by lowering the heating temperature to offset the excessive energy generated in the heating stage.

[0080] If the actual ambient temperature is lower than the standard ambient temperature, the calculated first energy value will be less than the second energy value, which means that the energy value generated in the heating stage of the preheating period is too low, and the energy value generated needs to be increased in the subsequent stages of the preheating period. Specifically, the energy value can be increased by increasing the heating temperature, thereby making up for some of the energy lost in the heating stage.

[0081] In one implementation of the embodiment of the present application, adjusting the heating temperature of the heating element in the preheating process from the first time point to the second time point includes:

[0082] The heating temperature of the preheating process of the heating element from the third time point to the second time point is adjusted; wherein the third time point is the time point recorded in the standard temperature curve when the heating element enters the temperature stabilization stage of the preheating process.

[0083] In order to offset the energy deviation generated in the temperature rise stage of the preheating period, it is theoretically feasible to adjust the heating temperature in the transition stage or the temperature stabilization stage. However, the transition stage is the stage in which the heating element is maintained at the highest preheating temperature. If the heating temperature in the transition stage is adjusted, it is equivalent to changing the highest preheating temperature, which will have a certain adverse effect on the normal suction performance of the device. Therefore, the best option is to keep the heating temperature in the transition stage unchanged and adjust the heating temperature in the temperature stabilization stage. Assuming that the time point at which the heating element enters the temperature stabilization stage of the preheating process recorded in the standard temperature curve is the third time point, the heating temperature of the preheating process of the heating element from the third time point to the second time point is adjusted. For example, if the first energy value is greater than the second energy value, the heating temperature of the preheating process of the heating element from the third time point to the second time point is reduced; if the first energy value is less than the second energy value, the heating temperature of the preheating process of the heating element from the third time point to the second time point is increased.

[0084] In one implementation of the embodiment of the present application, adjusting the heating temperature of the heating element during the preheating process from the third time point to the second time point includes:

[0085] (1) calculating an energy difference between a first energy value and a second energy value;

[0086] (2) determining a target temperature of the heating element during a preheating process from the third time point to the second time point according to the energy difference;

[0087] (3) According to the target temperature, the preheating process of the heating element from the third time point to the second time point is heated and controlled.

[0088] In order to achieve a more accurate energy control effect, the energy difference between the first energy value and the second energy value is first calculated. According to the energy difference, the target temperature of the preheating process of the heating element from the third time point to the second time point can be determined. Finally, according to the target temperature, the preheating process of the heating element from the third time point to the second time point is heated and controlled. The preheating process from the third time point to the second time point belongs to the temperature stabilization stage, and the heating temperature of the heating element is basically stable, that is, maintained at the target temperature. Assuming that the first energy value is P1, the second energy value is P2, P1>P2, then the energy difference X=P1-P2 is first calculated, which means that too much energy value X is generated in the heating stage, and the energy value X needs to be reduced in the temperature stabilization stage. Afterwards, based on the prerequisite of reducing the energy value X, it can be calculated what temperature the temperature stabilization stage needs to be reduced to, so as to determine the target temperature T1, and finally the preheating process of the heating element from the third time point to the second time point is controlled to be maintained at the target temperature T1.

[0089] In one implementation of the embodiment of the present application, determining the target temperature of the preheating process of the heating element from the third time point to the second time point according to the energy difference includes:

[0090] (1) Obtaining the standard temperature corresponding to the temperature stabilization stage recorded in the standard temperature curve;

[0091] (2) Calculate the target temperature based on the third time point, the second time point, the energy difference and the standard temperature.

[0092] When calculating the target temperature, first obtain the standard temperature corresponding to the temperature stabilization stage recorded in the standard temperature curve, and then calculate the target temperature based on the third time point, the second time point, the energy difference and the standard temperature. Specifically, the time between the third time point and the second time point can be calculated first, and then the energy difference divided by the time can be calculated to obtain the temperature change, and finally the target temperature can be calculated based on the standard temperature and the temperature change.

[0093] As an example, Figure 3 It is a schematic diagram of the principle of achieving energy deviation balance during the preheating period using the preheating control method provided in the embodiment of the present application. Figure 3 The actual temperature curve C1 and the standard temperature curve C2 are shown, wherein the actual temperature curve C1 corresponds to an ambient temperature of 40°C, and the standard temperature curve corresponds to an ambient temperature of 25°C. Tmax represents the maximum preheating temperature, T1 represents the target temperature, T2 represents the standard temperature, t0 represents the time point when the preheating period starts, t1 represents the time point when the heating element in the standard temperature curve C2 reaches the maximum preheating temperature, t2 represents the time point when the temperature stabilizes, and t3 represents the time point when the preheating period ends. Figure 3It can be seen that since the actual ambient temperature is higher than the standard ambient temperature, the heating element heats up faster. In the time period t0-t1, the actual energy value generated by the heating element will exceed the standard value, and an energy difference X is generated at this time, such as Figure 3 This energy difference needs to be offset during the temperature stabilization phase, that is, during the time period t2-t3, the heating temperature needs to be reduced from the standard temperature T2 to the target temperature T1, thereby reducing the energy value X. When calculating the target temperature T1, Figure 3 The shaded area on the right is approximately regarded as a rectangle. The area of ​​the rectangle is X and the length is t3-t2. In this way, the height H of the rectangle can be calculated as X / (t3-t2). Finally, T2-H is calculated to get the target temperature T1. By lowering the heating temperature of the heating element to the target temperature T1 during the temperature stabilization stage, the energy difference can be offset, so that the energy generated by the heating element during preheating at different ambient temperatures is close to the standard energy value.

[0094] In the technical solution of the embodiment of the present application, when the heating-not-burning appliance starts preheating and reaches the first time point, the first energy value currently generated by the heating element is detected. Due to the influence of the ambient temperature, the time when the heating element actually heats up to reach the highest preheating temperature may deviate from the first time point, which will cause the first energy value to be different from the second energy value, thereby affecting the energy generated during the entire preheating period. In order to balance the energy deviation, the heating temperature of the preheating process of the heating element from the first time point to the second time point is adjusted, so that the energy generated by the preheating process from the first time point to the second time point can be controlled to offset the deviation between the first energy value and the second energy value, so that the actual energy value generated by the heating element during the entire preheating period is close to the standard energy value. For example, if the ambient temperature is high, the heating element will heat up faster to reach the highest preheating temperature, so that when the preheating reaches the first time point, the first energy value generated by the heating element will be greater than the second energy value. At this time, the heating temperature of the preheating process from the first time point to the second time point can be reduced, so that the energy generated by the preheating process from the first time point to the second time point is reduced, and the energy difference is offset. It can be seen that through such an arrangement, the energy generated by the preheating of the heating element at different ambient temperatures can be close to the standard energy value, thereby avoiding problems such as scalding the mouth when smoking or insufficient preheating energy.

[0095] To facilitate understanding of the preheating control method for a heating-not-burning appliance provided in an embodiment of the present application, an actual application scenario is listed below.

[0096] like Figure 4 FIG. 1 is a schematic diagram of the operation flow of the preheating control method for a heating-without-combustion appliance provided in an embodiment of the present application in an actual application scenario. Figure 4In the heating-not-burning appliance, after the user presses a button, the heating module is started and the preheating process is entered; the time point t1 when the heating element reaches the highest preheating temperature, the standard temperature T2 in the temperature stabilization stage, and the energy value P2 generated when the heating element reaches the highest preheating temperature according to the standard temperature curve are read; when heated to the time point t1 according to the standard temperature curve, the energy value P1 actually generated by the heating element is calculated; the energy difference X between the energy value P1 and the energy value P2 is calculated; according to the time point t2 when the temperature stabilization stage is entered, the time point t3 when the preheating period ends, the energy difference X and the standard temperature T2, the target temperature T1 can be calculated; finally, the heating element is controlled to maintain the target temperature T1 in the temperature stabilization stage until the preheating period ends. The above process can make the energy generated by the heating element during preheating at different ambient temperatures close to the standard energy value by adjusting the heating temperature in the temperature stabilization stage, so that there will be no problem of scalding the mouth when sucking or insufficient preheating energy.
