As shown in fig. 1, the aerosol generating device 100 includes an aerosol output end 10, N sections of heating elements 20, and a smoke tube 30. The smoke tube 30 is used for accommodating cigarettes Y1, and the cigarettes can be traditional cigarettes or special-made smoke cartridges. The N sections of heating elements 20 surround the outer surface of the smoke tube 30, and the N sections of heating elements 20 are arranged at intervals. Wherein, N section heat-generating body 20 includes 1 st section heat-generating body 201 to N section heat-generating body 20N, and 1 st section heat-generating body 201 to N section heat-generating body 20N are along keeping away from gradually the direction of aerosol output 10 is arranged in proper order. The i +1 th section of heating element 20i +1 is farther away from the aerosol output end 10 of the aerosol generating device 100 than the i th section of heating element 20 i. Wherein the aerosol output 10 is a port at which the aerosol-generating device 100 outputs aerosol for inhalation by a user, for example, the aerosol output 10 may be a filter end.
The aerosol-generating device 100 further comprises an atomizing assembly 40, wherein the atomizing assembly 40 is disposed adjacent to the smoke tube 30 and is arranged with the smoke tube 30 along a direction gradually away from the aerosol output end 10. The extending direction of the smoke tube 30 is the same as the arrangement direction of the atomization assembly 40 and the smoke tube 30, and the smoke tube 30 is farther away from the aerosol output end 10 than the atomization assembly 40.
In an embodiment, be equipped with essential oil in the atomization component 40, wherein, when carrying out a cigarette smoking, pass through as heat-generating body 20 the tobacco pipe 30 is to holding a cigarette Y1 heating in the tobacco pipe 30 and when producing the flue gas, essential oil is also heated and atomizing/vaporization forms atomizing gas, the flue gas arrives through the tobacco pipe 30 atomization component 40, and with atomizing gas mixes and obtains mixed aerosol, then mixed aerosol reachs aerosol output 10 to supply the user to smoke. Wherein, the essential oil in the atomizing assembly 40 can be atomized by the smoke reaching the atomizing assembly 40.

In other embodiments, the aerosol-generating device may also be without the atomizing assembly and the essential oil, i.e. the aerosol has no atomizing gas but only flue gas, and the aerosol reaches the aerosol output end 10 after being cooled by the cooling channel.
It will be appreciated that the configuration of the aerosol-generating device of figure 1 is merely a block diagram of a portion of the configuration associated with an embodiment of the invention and does not constitute a limitation on the aerosol-generating device to which an embodiment of the invention may be applied, and that a particular aerosol-generating device may include more or fewer components than shown in the figures, or some components may be combined, or have a different arrangement of components. For example, in some embodiments, the essential oil in the atomizing component of the aerosol-generating device can also be a solid fragrance; in some embodiments, the aerosol-generating device may also be devoid of an atomizing component and essential oil; in some embodiments, the N-segment heating element can also be arranged inside the smoke tube.
Hereinafter, a heat generation control method provided by an embodiment of the present invention will be described in detail with reference to the aerosol-generating device in fig. 1.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a heating control method according to an embodiment of the present invention.
As shown in fig. 2, the heat generation control method includes steps S101 to S104.
S101, acquiring the integral initial temperature of N sections of heating elements;
s102, acquiring preset temperature control data, wherein the preset temperature control data comprise target temperatures of N sections of heating elements at different time points in a heating stage of cigarettes;
step S103, determining the starting time point of heating of the N sections of heating elements from preset temperature control data according to the integral initial temperature;
and step S104, controlling the N sections of heating bodies to heat according to the starting time points of the N sections of heating bodies for heating and preset temperature control data.
In the embodiment of the invention, the starting time point of the N sections of heating bodies for heating can be determined in the preset temperature control data in a self-adaptive manner based on the overall initial temperature by acquiring the overall initial temperature of the N sections of heating bodies and acquiring the preset temperature control data, and then the N sections of heating bodies are controlled to heat according to the starting time point of the N sections of heating bodies for heating and the preset temperature control data, so that the heating time of the heating bodies is adjusted in a self-adaptive manner based on the overall initial temperature, the excessive heating of the traditional cigarette is avoided when the traditional cigarette is continuously heated by using the aerosol generating device, and the problem that the aerosol generated by the aerosol generating device is higher in temperature and causes the excessive heating of the aerosol when a user continuously heats the traditional cigarette to generate the aerosol for smoking is solved.
It can be understood that, since the ending time point of the heating stage of the cigarette in the preset temperature control data is fixed, the higher the overall initial temperature of the N sections of heating elements is, the later the starting time point of the N sections of heating elements in the preset temperature control data is, the shorter the time for the N sections of heating elements to heat is. Similarly, the lower the overall initial temperature of the N sections of heating elements is, the earlier the starting time point of the N sections of heating elements for heating in the preset temperature control data is, so that the longer the heating time of the N sections of heating elements is, thereby realizing the self-adaptive adjustment of the heating time of the N sections of heating elements based on the overall initial temperature.
In one embodiment, the method comprises the steps of responding to the triggering operation of a user on an opening key of the aerosol generating device, and obtaining the integral initial temperature of N sections of heating elements; acquiring preset temperature control data; determining the starting time point of heating of the N sections of heating bodies from preset temperature control data according to the integral initial temperature; and controlling the N sections of heating bodies to heat according to the starting time point of the N sections of heating bodies to heat and preset temperature control data. When the starting button of the aerosol generating device is pressed by a user, based on the integral initial temperature of the N sections of heating bodies, the starting time point of heating of the N sections of heating bodies can be determined in a self-adaptive mode according to the preset temperature control data, the starting time point of heating and the preset temperature control data are carried out according to the N sections of heating bodies, and after the N sections of heating bodies are controlled to heat, the problem that when the user continuously uses the aerosol generating device to heat a traditional cigarette to generate aerosol to suck, the temperature of the aerosol generated by the aerosol generating device is high, and the aerosol is hot to a mouth is caused can be solved.
In an embodiment, the overall initial temperature of the N segments of heating elements may be acquired by the temperature sensor when it is detected that the user presses the start key of the aerosol generating device, or may be determined according to the current temperature of the N segments of heating elements when it is detected that the user presses the start key of the aerosol generating device. For example, in response to a user's trigger operation on an on button of the aerosol generating device, the temperature collected by the temperature sensor is acquired, and the temperature collected by the temperature sensor is determined as the overall initial temperature of the N segments of heating elements.
In one embodiment, as shown in fig. 3, step S101 includes sub-steps S1011 to S1012.
Step S1011, obtaining the initial temperature corresponding to each section of heating element;
and a substep S1012 of determining the overall initial temperature of the N sections of heating elements according to the initial temperature corresponding to each section of heating element.
In the embodiment of the invention, the integral initial temperature of the N sections of heating elements can be obtained through comprehensive calculation according to the initial temperature corresponding to each section of heating element, and the accuracy of the integral initial temperature is improved. The initial temperature corresponding to each section of heating element is the current temperature corresponding to each section of heating element when detecting that a user presses an opening key of the aerosol generating device.
In an embodiment, the N sections of heating elements are thermistors, and the manner of obtaining the initial temperature corresponding to the heating elements may be: responding to the triggering operation of a user on an opening key of the aerosol generating device, and acquiring the current resistance value of the heating element; and obtaining the temperature corresponding to the current resistance value according to the preset corresponding relation between the resistance value and the temperature of the heating body, and determining the temperature corresponding to the current resistance value as the initial temperature of the heating body. The thermistor may be a thermistor having a positive Temperature Coefficient of Resistance (TCR), i.e., a positive correlation between a resistance value and a temperature, and the correspondence between the resistance value of the heating element and the temperature may be obtained in advance from the positive correlation between the resistance value and the temperature inherent to the thermistor.
It is to be understood that the current resistance value of the heating element may be directly measured by the resistance measurement circuit, or may be calculated by the voltage applied to the heating element and the current passing through the heating element, which is not specifically limited in this embodiment of the present invention. It is to be understood that in other embodiments, the initial temperature of the heat-generating body may be directly measured by a temperature sensor or the like.
In an embodiment, the manner of determining the overall initial temperatures of the N sections of heating elements according to the initial temperatures corresponding to the respective sections of heating elements may be: acquiring weighting coefficients corresponding to all sections of heating bodies; for each section of heating element, calculating the product of the initial temperature of the heating element and the weighting coefficient corresponding to the heating element to obtain the weighting temperature of each section of heating element; and accumulating the weighted temperatures of the heating elements in each section to obtain the integral initial temperature of the N sections of heating elements. The accurate integral initial temperature can be obtained by weighting and summing the initial temperatures corresponding to all the sections of heating bodies.
In one embodiment, the weighting factor of the heating element is inversely related to the target distance, and the target distance is the distance between the heating element and the aerosol output end of the aerosol generating device. It can be understood that the closer the distance between the heating element and the aerosol output end of the aerosol generating device, the larger the weighting coefficient corresponding to the heating element, and the farther the distance between the heating element and the aerosol output end of the aerosol generating device, the smaller the weighting coefficient corresponding to the heating element. The weighting coefficients corresponding to the heating elements of each segment may be set based on actual conditions, which is not specifically limited in the embodiment of the present invention.
In one embodiment, the integral initial temperature T = T of the N sections of heating bodies 1 *β 1 +T 2 *β 2 +....+T N *β N Wherein T is the integral initial temperature of the N sections of heating bodies, T 1 Is the initial temperature of the section 1 heating element, beta 1 A weighting factor, T, corresponding to the section 1 heating element 2 Is the initial temperature of the stage 2 heating element, beta 2 A weighting factor, T, corresponding to the section 2 heat-generating body N Is the initial temperature of the Nth stage heating element, beta N Is the weighting coefficient corresponding to the section 2 heating element. For example, taking N =4, that is, the aerosol generating device includes 4 segments of heating elements, the overall initial temperature T = T of the 4 segments of heating elements can be calculated according to the above formula 1 *β 1 +T 2 *β 2 +T 3 *β 3 +T 4 *β 4 Is provided with beta 1 ＝0.8、β 2 ＝0.4、β 3 =0.2 and β 4 =0.2, then T = T 1 *0.8+T 2 *0.4+T 3 *0.2+T 4 *0.2, set T 1 ＝160、T 2 ＝180、T 3 =200 and T 4 T =160 + 0.8+180 + 0.4+200 + 200.2 + 0.2=280 degrees celsius.
In one embodiment, the sum of the weighting coefficients corresponding to the respective heat generating elements is equal to 1. For example, let beta 1 ＝0.7、β 2 ＝0.1、β 3 =0.1 and β 4 =0.1, and T 1 ＝200、T 2 ＝220、T 3 =240 and T 4 =280, then overall initial temperature T = 200.7 + 220.1 + 0.1+280 + 0.1=214 degrees celsius. Also for example, let beta 1 ＝0.6、β 2 ＝0.2、β 3 =0.1 and β 4 =0.1, and T 1 ＝200、T 2 ＝220、T 3 =240 and T 4 And =280, the overall initial temperature T =200 + 0.6+220 + 0.2+240 + 0.1+280 + 0.1 of 4 segments of heating body is 216 degree centigrade.
In an embodiment, the preset temperature control data includes target temperatures of N sections of heating elements at different time points in the heating stage of the cigarette, that is, the preset temperature control data includes target temperatures of each section of heating elements from the i-th section of heating element to the N-th section of heating element at different time points in the heating stage of the cigarette. It is understood that the preset temperature control data may be in the form of a table or a curve. For example, N =4, the preset temperature control data includes target temperatures of the section 1 heating element, the section 2 heating element, the section 3 heating element and the section 4 heating element at different time points in the heating stage of the cigarette.
Referring to fig. 4, fig. 4 is a schematic diagram of a target temperature curve for controlling 4 sections of heating elements to generate heat according to an embodiment of the present invention. The 4-entry standard temperature curves C1-C4 are illustrated in FIG. 4. As shown in fig. 4, 4 item temperature curves C1-C4 are set to define target temperatures of the section 1 heating element, the section 2 heating element, the section 3 heating element and the section 4 heating element at different time points in the heating stage of the cigarette. The time points in the embodiment of the present invention may be time slices, the abscissa in fig. 4 is a time slice, each time slice corresponds to 2 seconds, and the ordinate in fig. 4 is a temperature.
In an embodiment, the preset temperature control data includes M time points corresponding to a heating stage of the cigarette and target temperatures of each section of heating element at each time point from a 1 st time point to an M th time point, where M is an integer greater than or equal to 2, and the manner of determining the starting time point of heating by the N sections of heating elements from the preset temperature control data according to the overall initial temperature may include: sequentially comparing the target temperature of each section of heating element in the N sections of heating elements at each time point with the integral initial temperature according to the sequence from the 1 st time point to the jth time point, wherein j is less than M; and when the target temperature is greater than or equal to the overall initial temperature, determining the current time point for comparison as the starting time point for heating of the N sections of heating bodies. Wherein, the 1 st time point is the starting time point of the heating stage of the cigarette, and the jth time point is the ending time point of the preheating completion of the cigarette in the heating stage of the cigarette. According to the sequence from morning to evening, the target temperature of each section of the N sections of heating bodies corresponding to each time point is compared with the integral initial temperature in sequence, and the starting time point of the N sections of heating bodies for heating can be accurately determined.
In an embodiment, the manner of determining the starting time points of the heating of the N sections of heating elements from the preset temperature control data according to the overall initial temperature may include: sequentially comparing the target temperature of each section of heating element in the N sections of heating elements at each time point with the integral initial temperature according to the sequence from the 1 st time point to the jth time point; and when the target temperature of each time point for comparison is less than the integral initial temperature, determining the j-k time points as the starting time points of the heating of the N sections of heating elements, wherein k is an integer which is greater than or equal to 0 and less than or equal to j/3.
It can be understood that when k =0, the target temperature of each heating element of the N sections of heating elements at each time point is less than the overall initial temperature, the starting time point of heating by the N sections of heating elements is the jth time point in the preset temperature control data, that is, the N sections of heating elements do not need to heat in the preheating stage of the heating stage of the cigarette. When k is 1, 2, 3, 4 or 5, and the target temperature of each section of heating element in the N sections of heating elements at each time point is less than the integral initial temperature, the starting time point of heating of the N sections of heating elements is the j-1 th, j-2 th, j-3 th, j-4 th or j-5 th time point in the preset temperature control data, so that the N sections of heating elements can be prevented from skipping the preheating stage in the heating stage of the cigarette, and the problem of insufficient generated aerosol caused by the fact that the N sections of heating elements skip the preheating stage of the cigarette can be solved.
For example, j =15, as shown in fig. 4, the ending time point of the completion of the preheating of the cigarettes in the heating stage of the cigarettes is the 15 th time slice, that is, the 1 st time slice to the 15 th time slice in the heating stage of the cigarettes are the preheating stage of the cigarettes, the stages after the 15 th time slice are the smoking stage of the cigarettes, and the duration of the preheating stage of the cigarettes is 30 seconds. Setting the overall initial temperature T =30 degrees celsius, as shown in fig. 4, sequentially comparing the target temperatures of the 1 st section of heating element, the 2 nd section of heating element, the 3 rd section of heating element and the 4 th section of heating element at each time slice with the overall initial temperature according to the sequence from the 1 st time slice to the 15 th time slice, and determining the 1 st time slice as the starting time point of the 4 sections of heating elements because the target temperature of the 1 st section of heating element at the 1 st time slice is 40 degrees celsius and is greater than 30 degrees celsius.
For another example, assuming that the total starting temperature T =240 degrees celsius of the 4-stage heat generating body, the target temperatures of the 1 st stage heat generating body, the 2 nd stage heat generating body, the 3 rd stage heat generating body and the 4 th stage heat generating body at the respective time slices are compared with the total starting temperature in the order of the 1 st time slice to the 15 th time slice, and since the target temperature of the 1 st stage heat generating body at the 7 th time slice is 240 degrees celsius, the same as the total starting temperature T =240 degrees celsius, and the target temperatures of the 2 nd stage heat generating body, the 3 rd stage heat generating body and the 4 th stage heat generating body at the 7 th time slice are zero, the 7 th time slice is determined as the starting time point of the 4-stage heat generating body.
For another example, assuming that the target temperature curve C1 defines target temperatures of the section 2 heating element at different time points in the heating stage of the cigarette, and the target temperature curves C2 to C4 define target temperatures of the section 1 heating element, the section 3 heating element and the section 4 heating element at different time points in the heating stage of the cigarette, respectively, and setting a total initial temperature T =240 degrees celsius of the section 4 heating element, as shown in fig. 4, the target temperatures of the section 1 heating element, the section 2 heating element, the section 3 heating element and the section 4 heating element at the respective time slices are compared with the total initial temperature in sequence from the 1 st time slice to the 15 th time slice, and since the target temperature of the section 2 heating element at the 7 th time slice is 240 degrees celsius, the same as the total initial temperature T =240 degrees celsius, and the target temperatures of the section 1 heating element, the section 3 heating element and the section 4 7 th time slice are zero, the section 7 th time slice is determined as the starting time point of the section 4 heating element.
For example, if the overall initial temperature T =320 degrees celsius, k =0, and j =15, as shown in fig. 4, the target temperatures of the 1 st section of heating element, the 2 nd section of heating element, the 3 rd section of heating element, and the 4 th section of heating element at each time slice are sequentially compared with the overall initial temperature according to the sequence from the 1 st time slice to the 15 th time slice, and since the target temperatures of the 1 st section of heating element, the 2 nd section of heating element, the 3 rd section of heating element, and the 4 th section of heating element at each time slice are all less than 320 degrees celsius, the 15 th time slice is determined as the starting time point of heating by the 4 th section of heating element, so that in the subsequent process of controlling the 4 sections of heating element to generate heat according to the target temperatures of the 15 th time slice and the following 15 th time slice, the 1 st section of heating element, the 2 nd section of heating element, that is, the 3 rd section of heating element, and the 4 th section of heating element do not need to generate heat in the preheating stage of the heating element in the preheating cigarette, and the 4 sections of heating element skip the preheating stage of the cigarette.

In the embodiment of the invention, when the triggering operation of a user on an opening key of the aerosol generating device is detected, the existing aerosol generating device controls N sections of heating bodies to heat by using preset temperature control data so as to heat cigarettes accommodated in a smoke tube, and prompts the user to finish preheating the cigarettes after the heating time of the N sections of heating bodies reaches the preset cigarette preheating time, so that smoking can be performed. By the heating method provided by the embodiment of the invention, the self-adaptive adjustment of the heating time of the N sections of heating bodies based on the integral initial temperature is realized, the excessive heating of the traditional cigarette is avoided when the aerosol generating device is continuously used for heating the traditional cigarette, and the problem that the aerosol generated by the aerosol generating device is higher in temperature and the aerosol is overheated to scald the mouth when a user continuously uses the aerosol generating device to heat the traditional cigarette to generate the aerosol for smoking is solved.
Wherein the target temperature control data includes target temperatures of the N segments of the heating elements at respective time points from the start time point to the end time point. For example, as shown in fig. 4, if the starting time point of the 4 segments of the heating elements including the 1 st segment of the heating element, the 2 nd segment of the heating element, the 3 rd segment of the heating element, and the 4 th segment of the heating element for heating is the 7 th time slice, the target temperature control data includes the target temperatures of the 1 st segment of the heating element, the 2 nd segment of the heating element, the 3 rd segment of the heating element, and the 4 th segment of the heating element in the 7 th time slice and the time slices after the 7 th time slice in fig. 4, so that the aerosol generating device controls the 1 st segment of the heating element, the 2 nd segment of the heating element, the 3 rd segment of the heating element, and the 4 th segment of the heating element to generate heat according to the target temperatures of the 1 st segment of the heating element, the 2 nd segment of the heating element, and the 3 rd segment of the heating element in the 7 th time slice and after the 7 th time slice in fig. 4, and the preheating time period of the aerosol generating device to the cigarette is adjusted from 30 seconds to 18 seconds.
For example, when a user uses the aerosol generating device to suck a first cigarette, according to the prior art, the overall initial temperature of the 4 sections of heating elements is not considered, but preset temperature control data is used to control the 4 sections of heating elements to generate heat, that is, the aerosol generating device starts to control the 4 sections of heating elements to generate heat from the 1 st time slice, and after the 4 sections of heating elements generate heat for 30 seconds, the aerosol generating device completes preheating the cigarette, and prompts the user that the user can use the aerosol generating device to suck the cigarette. In a short time after a user sucks a first cigarette by using the aerosol generating device, the user sucks a second cigarette by using the aerosol generating device, the integral initial temperature T =240 ℃ at the moment of the 4 sections of heating bodies is set, according to the prior technical scheme, after the 4 sections of heating bodies are required to be controlled to still heat for 30 seconds, the sol generating device finishes preheating the cigarettes, and prompts that the user can suck the cigarettes by using the aerosol generating device, and the problem that the temperature of the aerosol generated by the aerosol generating device is high due to the fact that the integral initial temperature of the 4 sections of heating bodies is high and the 4 sections of heating bodies are controlled to still heat for 30 seconds, and the mouth is scalded due to overheating of the aerosol is caused.
By adopting the heating control method provided by the embodiment of the invention, under the condition that the overall initial temperature T =240 ℃ of the 4-section heating element, as shown in fig. 4, the target temperatures of the 1 st-section heating element, the 2 nd-section heating element, the 3 rd-section heating element and the 4 th-section heating element in each time slice are compared with the overall initial temperature in sequence from the 1 st time slice to the 15 th time slice, because the target temperature of the 1 st-section heating element in the 7 th time slice is 240 ℃ and is the same as the overall initial temperature T =240 ℃, the 7 th time slice is determined as the starting time point of heating of the 4-section heating element, so that the 4-section heating element is controlled to generate heat according to the target temperatures of the 4-section heating element in the 7 th time slice and the time slices after the 7 th time slice, and the aerosol generating device completes preheating of the cigarette after the 4-section heating element is heated for 18 seconds, and the user is prompted to use the aerosol generating device to smoke cigarettes, thereby avoiding the problem that the aerosol generated by the aerosol generating device when the traditional user continuously uses the aerosol generating device to heat the aerosol to smoke the cigarettes to cause the aerosol.
In an embodiment, according to the target temperature control data, the method for controlling the N sections of heating elements to generate heat may be: controlling the i-th section of heating element to heat according to the target temperature control data, wherein the heating process of the i-th section of heating element comprises a first stage, a second stage and a third stage which are sequentially carried out, i is more than or equal to 1 and less than N, and N is more than or equal to 2; and when the ith section of heating element is in the second stage or the third stage, controlling the (i + 1) th section of heating element to heat according to the target temperature control data. Wherein, the (i + 1) th section of heating element is farther away from the aerosol output end of the aerosol generating device than the (i) th section of heating element.

And starting to control the heating of the section 2 heating element in the third stage by using the target temperature of each time slice from the 37 th time slice to the final ending time slice, namely, the time period corresponding to the third stage of the section 2 heating element is the time period from 102S to the ending.
As shown in the target temperature curve C3, for the 3 rd stage heating element, when it is detected that the user presses the start key of the aerosol generating device, the 3 rd stage heating element does not heat during the period from the 7 th time slice to the 50 th time slice, and then the target temperature of each time slice in the 50 th to 62 th time slices is used to start controlling the 3 rd stage heating element to heat in the first stage, that is, the time period corresponding to the first stage of the 3 rd stage heating element is 88-112S. And starting to control the heat generation of the section 3 heat generating body in the second stage by using the target temperature of each time slice in the 62 th to 83 th time slices, namely, the time period corresponding to the second stage of the section 3 heat generating body is 112-154S.

In an embodiment, when the (i + 1) th section is an nth section, the heating process of the (i + 1) th heating element includes a first stage and a second stage which are sequentially performed. When the (i + 1) th section of heating element is the nth section of heating element, that is, the last section of heating element, the heating process of the (i + 1) th section of heating element may only include a first stage and a second stage which are sequentially performed. For example, as shown in the target temperature curve C4, when it is detected that the user presses the start button of the aerosol generating device, the 4 th segment of the heating element does not generate heat during the period from the 7 th time slice to the 75 th time slice, and then the target temperature of each of the 75 th to 85 th time slices is used to start controlling the heating of the 4 th segment of the heating element in the first stage, that is, the time period corresponding to the first stage of the 4 th segment of the heating element is 138 to 158S.
