The sol output terminal 10 is for the user to inhale.

Wherein, Fig. 1 introduces the basic structure of the aerosol generating device 100, based on the above basic structure, the present application provides a heating control method for generating aerosol. However, it should be understood that the heating control method for generating aerosol of the present application is not limited to be applied to the structure shown in FIG. 1 .

Please refer to FIG. 2 , which is a heating control method of nebulizable essential oil in an embodiment of the present application. The heating control method can be used in the aforementioned aerosol generating device 100. As mentioned above, the aerosol generating device includes An atomization assembly, a smoke pipe and a heating body, the smoke pipe is used to accommodate smoking products, the heating body is used to heat the smoke products contained in the smoke pipe, the atomization assembly includes an atomization core, the The atomizing core is used to exude essential oil when the temperature reaches a certain level, and the smoke pipe is arranged adjacent to the atomizing core. As shown in Figure 2, the heating control method may include the following steps:

201. In response to a heating trigger operation, control the heating body to start heating.

Wherein, the heating trigger operation may be a pressing operation of an on button of the aerosol generating device. In some embodiments, the user can place the smoking product to be smoked in the aerosol generating device, and press the start button to start the smoking process. Therefore, when it is detected that the user presses the start button, it is determined that smoking of the smoking product is currently started, and the heating body is controlled to start heating.

202. Control to raise the temperature of the heating body to at least the first target temperature within a preset period of time, so as to heat the smoking articles contained in the tobacco tube to generate aerosol, and make the atomizing core exuding essential oil and atomizing the essential oil, and finally generating an aerosol mixed with essential oil, wherein the first target temperature is such that the smoking product can generate an aerosol, and the atomizing core is exuding essential oil and atomizing The temperature of the essential oil.

Therefore, in this application, the essential oil is simultaneously atomized through the heating body used to heat the smoking product, effectively saving costs, and by controlling the temperature of the heating body to at least rise to the first target temperature within a preset period of time, Able to ensure fast delivery of aerosols mixed with essential oils. And because the aerosol generated by essential oil and smoking products is mixed into an aerosol with essential oil, the taste can be further improved.

Among them, the heating control method for generating aerosol of the present application is used to control the temperature at which the heating body generates heat, so that the smoking product is heated by the heating body. Therefore, the temperature of the smoking product and essential oil is proportional to the temperature of the heating body. Correlation, through the temperature control of the heating body, the temperature control of the smoking product and the essential oil can be correspondingly realized, and the final aerosol mixed with the essential oil can be quickly output.

In some embodiments, the control raises the temperature of the heating body to at least a first target temperature within a preset period of time, so as to heat the smoking article contained in the tobacco pipe to generate an aerosol, and Making the atomizing core exude essential oil and atomizing the essential oil includes: controlling the temperature of the heating body to be raised to at least the first target temperature within a preset period of time so that the smoke product in the smoke tube generates Aerosol, and then through the aerosol to make the atomization core seep essential oil and atomize the essential oil; or control the temperature of the heating body to at least rise to the first target temperature within a preset period of time so that the The smoking product in the cigarette tube generates aerosol, and makes the atomizing core exude essential oil and be atomized.

That is, in some embodiments, the atomizing core is arranged adjacent to the smoke pipe, but there is a certain distance. In particular, when the smoking product is accommodated in the smoke pipe and is in the extreme extension position, the smoking product and the smoke pipe The atomization core has a certain distance. In this case, in order to control the temperature of the heating body to be raised to at least the first target temperature within a preset period of time so that the smoke products in the smoke pipe generate a higher The aerosol at a higher temperature passes through the aerosol at a higher temperature so that the atomizing core seeps out the essential oil and atomizes the essential oil. In some other embodiments, the atomizing core is arranged adjacent to the smoke pipe, and they are relatively close to each other. In particular, when the smoking product is accommodated in the smoke pipe and is at the extreme extension position, the smoking product and the smoke pipe The distance of the atomizing core is within a preset distance range, for example, within the range of -0.5mm (millimeter) -0.5mm, therefore, when the temperature of the heating body rises to the first target temperature, the atomizing The essential oil leaked from the core into the atomizing channel at least partly flows into the smoking product, and the heating body simultaneously heats the smoking product in the pipe and the essential oil flowing into the smoking product, so that the smoking product Generates an aerosol and aerosolizes the essential oils that flow into the smoking article.

In some embodiments, the heating process of the heating body includes a first stage and a second stage in sequence; the controlling raises the temperature of the heating body to at least a first target temperature within a preset period of time, including : In the first stage, control to raise the temperature of the heating body to at least a first target temperature within a preset time period.

That is, in some embodiments, the heating process of the heating body includes a plurality of stages, by controlling the temperature of the heating body to be raised to at least the first target within the preset time period in the first stage The temperature can further effectively ensure the output of aerosol as soon as possible.

In some embodiments, in the first stage, controlling to increase the temperature of the heating body to at least a first target temperature within a preset period of time includes: in the first stage, controlling the heating The body reaches the corresponding first target temperature by at least raising the temperature at a temperature change rate greater than 5° C./S within the preset time period.

That is, in some embodiments, in the first stage of heating of the heating body, the corresponding first target temperature is reached by controlling the heating body to at least increase the temperature at a temperature change rate greater than 5° C./S. Therefore, it is ensured that the first target temperature can be reached within the preset time period.

Specifically, in one embodiment, in the first stage, the heating body is controlled to raise the temperature at least at a temperature change rate greater than 5°C/S within the preset time period to reach the corresponding The first target temperature includes: controlling the heating body to heat up to a temperature greater than the first target temperature at a temperature change rate greater than 5°C/S during the first period of the first stage; and The temperature of the heating body is controlled to drop to the first target temperature during the second period of the first stage.

That is, in one embodiment, the preset time period for the temperature increase at a temperature change rate greater than 5°C/S may be the first period, by controlling the temperature during the first period of the first stage The heating body heats up to a temperature greater than the first target temperature at a temperature change rate greater than 5°C/S, which can make the temperature difference between the temperature of the smoking product and the temperature of the heating body larger, because the temperature increase rate is different from that of the heating body. The temperature difference is directly proportional, therefore, the temperature of the smoking product can be increased more quickly, and the aerosol can be generated as soon as possible and the essential oil can be atomized as soon as possible. Then, in the second period of time, the temperature is gradually lowered to the first target temperature, which can ensure that the temperature of the smoking product is not too high, avoid excessive carbonization of the smoking product, and avoid excessive volatilization of the essential oil.

In another embodiment, in the first stage, the heating body is controlled to increase the temperature at least at a temperature change rate greater than 5°C/S within the preset time period to reach the corresponding first Target temperature, including: controlling the heating body to heat up to the first target temperature at a temperature change rate greater than 5°C/S during the first period of the first stage; and during the second period of the first stage The internal control heating body maintains the first target temperature.

Therefore, in another embodiment, by controlling the heating body to heat up to the first target temperature at a temperature change rate greater than 5°C/S during the first period of the first stage, and within the second period Maintaining the first target temperature can ensure that the corresponding part of the smoking product produces aerosol quickly and can reduce the risk of over-carbonization.

Wherein, in some embodiments, the total duration of the first stage may be 30S, the aforementioned first period may be 20S (seconds), and the aforementioned second period may be 10S. Obviously, in some other embodiments, the total duration of the first stage and the duration of the first period and the second period may be other values, for example, the total duration of the first stage may be 25 seconds, and the first period may be 25 seconds. The duration of the first period and the second period may be 18 seconds, 7 seconds, etc. respectively.

Wherein, in some embodiments, the method further includes: controlling the heating of the heating body to enter a second stage; and in the second stage, controlling the temperature of the heating body to drop from the first target temperature to the second target temperature.

That is, in some embodiments, since the temperature of the heating body has reached the first target temperature in the first stage, the temperature of the part of the smoking article corresponding to the heating body is rapidly raised to a temperature at which aerosol and nebulizable essential oil can be generated, Therefore, the second stage is mainly to bake the smoking product. In the second stage, the temperature of the heating body can be lower than that of the first stage to maintain the temperature of the smoking product until the aerosol containing nicotine can be released stably. As well as stable nebulized essential oils. In some embodiments, the first target temperature is greater than or equal to 260°C, the second target temperature is less than the first target temperature, and the difference between the first target temperature and the second target temperature is less than or equal to 20°C.

In some embodiments, the controlling to decrease the temperature of the heating body from the first target temperature to a second target temperature during the second stage includes: during the first period of the second stage controlling the temperature of the heating body to drop from the first target temperature to a second target temperature; and controlling the heating body to maintain the second target temperature during a second period of the second stage. Therefore, by reducing the temperature to the second target temperature quickly and then maintaining it, the temperature of the smoking product can be maintained as early as possible to the point where the aerosol containing nicotine can be released stably and the nicotine concentration is similar to that of lighting an ordinary cigarette.

In some other embodiments, in the second stage, controlling to lower the temperature of the heating body from the first target temperature to the second target temperature includes: during the entire period of the second stage Controlling the temperature of the heating body to gradually drop from the first target temperature to the second target temperature. Therefore, by gradually lowering to the second target temperature, the temperature can be changed more slowly, so that the output of the aerosol is more stable.

In some embodiments, the first target temperature is within a first temperature range, and the second target temperature is within a second temperature range; the maximum value of the first temperature range is greater than the maximum value of the second temperature range value. That is, at least part of the range interval of the first temperature range where the first target temperature is located is greater than the maximum value of the second temperature range where the second target temperature is located.

In a further embodiment, the minimum value of the first temperature range is also greater than the minimum value of the second temperature range.

Therefore, by designing the temperature range, the first target temperature and the second target temperature are allowed to fluctuate within a certain range, so that even if there is a temperature measurement error, it can be ensured that the achieved first target temperature and the second target temperature meet the requirements.

Wherein, even though the first temperature range overlaps with the second temperature range, the second target temperature is obtained by decreasing from the first target temperature in the second stage, and is smaller than the first target temperature. Therefore, after selecting and determining the first target temperature from the first temperature range, in fact, the value of the second target temperature is between an upper limit value and the minimum value of the second temperature range a certain value, the upper limit being the smaller of the maximum value of the second temperature range and the first target temperature.

Please refer to FIG. 3 , which is a heating control method of nebulizable essential oil in another embodiment of the present application. The methods include:

301. In response to a heating trigger operation, control the heating body to start generating heat, wherein the heating process of the heating body includes a first stage and a second stage.

Wherein, the heating trigger operation may be a pressing operation of an on button of the aerosol generating device. In some embodiments, the user can place the smoking product to be smoked in the aerosol generating device, and press the start button to start the smoking process. Therefore, when it is detected that the user presses the start button, it is determined that smoking of the smoking product is currently started, and the heating body is controlled to start heating.

302. Control to raise the temperature of the heating body to at least the first target temperature within the preset period of time in the first stage, so as to heat the smoking articles contained in the tobacco pipe to generate aerosol, and make the The atomizing core exudes essential oil and atomizes the essential oil, and finally generates an aerosol mixed with essential oil, wherein the first target temperature is such that the smoking product can generate an aerosol, and the atomizing core exudes essential oil and mist the temperature of said essential oil.

303: Control the heating of the heating body to enter a second stage; and in the second stage, control to lower the temperature of the heating body from the first target temperature to a second target temperature.

Therefore, by designing the heating process of the heating body into two stages, and the temperature of the second stage is lower than that of the first stage, the heating body can quickly reach the first target temperature in the first stage to quickly generate aerosol and mist The essential oil, and then in the second stage, the temperature of the heating body is lower than that of the first stage, so as to maintain the temperature of the smoking product part to be able to stably release the aerosol containing nicotine and stably atomize the essential oil, so as to realize the mixing Aerosol with essential oils has a fast and steady output.

Wherein, the steps in FIG. 3 basically correspond to the steps in FIG. 2 , and for more specific content, please refer to the foregoing description.

Wherein, as shown in FIG. 1 , in some embodiments, the heating body includes a section, and a section of the heating body is integrally arranged on the smoke pipe, and heats the smoking products contained in the smoke pipe as a whole. . Wherein, the heating body may entirely surround the outer surface of the smoke pipe.

In some embodiments, when there is only one segment of the heating body, the heating process of the heating body may only include the above two stages.

Please refer to FIG. 4 , which is a schematic structural diagram of an aerosol generating device 100 in other embodiments of the present application. In some other embodiments, the smoke pipe 30 is provided with multiple stages of heating units J1 arranged at intervals, and the heating body 20 is the heating unit J1 closest to the atomizing core 41 . In some other embodiments, the heating process of the heating body further includes a third stage, and the heating control method further includes: controlling the heating body to enter the third stage; The temperature of the heating body is maintained within an auxiliary temperature maintaining range, wherein the maximum value of the auxiliary temperature maintaining range is less than the maximum value of the second temperature range, and the minimum value of the auxiliary temperature maintaining range is less than the second The minimum value of the temperature range.

That is, in some embodiments, when the heating process of the heating body includes the third stage, the heating body is controlled to maintain the heating body within an auxiliary temperature maintenance range, and the maximum value of the auxiliary temperature maintenance range is less than The maximum value of the second temperature range and the minimum value of the auxiliary temperature maintenance range are smaller than the minimum value of the second temperature range.

Wherein, by controlling and maintaining the heating body in an auxiliary temperature maintenance range, the temperature of the part of the smoking product corresponding to the heating body can be maintained, so that the aerosol generated by the part of the heating unit J1 corresponding to the smoking product in the next stage will not be adsorbed, Thus, loss can be reduced. Wherein, the heating unit J1 of the latter stage refers to the heating unit J1 adjacent to the heating body, that is, the heating unit J1 closest to the atomizing core 41 and further away from the atomizing core 41 .

In some embodiments, the maximum value of the auxiliary temperature maintenance range of the heating body may be smaller than the second target temperature of the heating body, but both the maximum value and the minimum value of the auxiliary temperature maintenance range of the heating body are greater than the corresponding The lowest value for aerosol-generating and nebulized essential oils for smoking products.

As shown in Figure 4, the multi-stage heating monomer J1 includes N-stage heating monomers, that is, the first heating monomer J11 to the N-th heating monomer J1N, and the first heating monomer J11 to the N-th heating monomer. The bodies J1N are arranged in sequence along the direction gradually away from the aerosol output end 10 . The heating body J1(i+1) of the i+1 stage is farther away from the aerosol output end 10 of the aerosol generating device 100 than the heating element J1 i of the i stage. Therefore, the first-stage heating unit J11 is the aforementioned heating unit J1 closest to the atomizing core 41 , that is, the aforementioned heating body.

In some embodiments, when the smoke pipe 30 is provided with multiple stages of heating units J1 arranged at intervals, the i-th heating unit J1 i includes the aforementioned first stage, second stage and third stage, which The control process is the same as the aforementioned heating body. Wherein, said i is greater than or equal to 1 and less than N, and N is greater than or equal to 2. Wherein, the method further includes: when the i-th stage heating element is in the second stage or the third stage, controlling the (i+1)th stage heating element to generate heat.

Therefore, in some embodiments, through the multi-stage heating of the monomer structure, independent heating of the smoking article is realized in sections, and since the first stage of heating the monomer in the i-th stage including the first stage includes at least a temperature greater than 5°C During the heating period with the temperature change rate of /S, the heating monomer in the first stage can quickly heat up to the temperature required for aerosol generation, ensuring rapid output of aerosol. And because when the heating element in the i-th stage is in the second stage or the third stage, the heating element in the i+1th stage is controlled to generate heat, so that each subsequent heating element can gradually generate heat so that the corresponding The aerosol generated when the part of the smoking product is heated will not be absorbed by the part of the smoking product corresponding to the front-stage heating monomer, thereby avoiding loss. Further, on the whole, in this application, by controlling the heat generation process of the heating monomer in the i-th stage, it includes the first stage, the second stage and the third stage in sequence, and the heating monomer in the i-th stage is in the In the second stage or the third stage, the heating element in the i+1 stage is controlled to generate heat, so that the aerosol can be evenly output.

The first temperature range of the heating element in the first stage is different from the first temperature range of the heating elements in other stages, and the second temperature range of the heating element in the first stage is also different from the second temperature range of the heating elements in other stages .

Specifically, the minimum value of the first temperature range where the first target temperature of the heating element in the first stage is located is greater than or equal to the maximum value of the first temperature range where the first target temperature of the heating element in the other stage is located. The maximum value of the second temperature range where the second target temperature of the heating monomer in the first stage is located is greater than the maximum value of the second temperature range where the second target temperature of the heating monomer in the other stages is located, and the heating monomer in the first stage The minimum value of the second temperature range where the second target temperature is located is greater than the minimum value of the second temperature range where the second target temperatures of the heating elements of other stages are located.

As previously mentioned, designing the first temperature range that the first target temperature of each section of the heating element can be in, and the second temperature range that the second target temperature of each section of the heating element can be in is to consider the measurement error, allowing the first The target temperature and the second target temperature fluctuate within a certain range, so that even if there is a temperature measurement error, it can be ensured that the first target temperature and the second target temperature reached by the heating monomers in each section meet the requirements. But even if the first temperature ranges of the heating elements in different sections overlap, and the second temperature ranges of the heating elements in different sections overlap, the first target temperature of the heating elements in the first section is higher than that of other heating elements For the first target temperature, the second target temperature of the heating monomer in the first stage is also higher than the second target temperature of the heating monomer in other stages.

In some embodiments, the first target temperature of the heating element in the first stage is greater than or equal to the first target temperature of the heating element in other stages, that is, in some embodiments, even if the first target temperature of the heating element in the first stage The first temperature range where the temperature is located overlaps with the first temperature range where the first target temperature of the other stage heating monomers is located, and the first target temperature of the first stage heating monomer is generally greater than Or equal to the first target temperature of other section heating monomers. In some embodiments, the second target temperature of the heating element in the first stage is also greater than or equal to the second target temperature of the heating element in other stages, that is, in some embodiments, even if the second target temperature of the heating element in the first stage The second temperature range where the target temperature is located overlaps with the second temperature range where the second target temperature of the other stage heating monomers is located, and the second target temperature of the first stage heating monomer is generally Greater than or equal to the second target temperature of heating monomers in other sections.

Please also refer to Figure 5, which is a schematic diagram of the temperature ranges of the heating monomers in different stages in an embodiment of the present application, as shown in Figure 5, specifically, when i=1, that is, when the i-th stage When the heating monomer is the first-stage heating monomer, the first temperature range is 280°C-300°C, that is, greater than or equal to 280°C and less than or equal to 300°C; the second temperature range is 260°C-290°C , that is, greater than or equal to 260°C and less than or equal to 290°C; when i is a value greater than 1, that is, when the heating monomer in the i-th stage is the heating monomer in other stages, the first temperature range is 260°C- 280°C, that is, greater than or equal to 260°C and less than or equal to 280°C; the second temperature range is 240°C-270°C, that is, greater than or equal to 240°C and less than or equal to 270°C.

Wherein, in some embodiments, N=4, and FIG. 5 schematically shows a 4-stage heating unit. Obviously, in other embodiments, N can also be other values greater than or equal to 2.

In some embodiments, the maximum value of the auxiliary temperature maintenance range of the i-th heating element may be less than the second target temperature of the i-th heating element, but the auxiliary temperature of the i-th heating element Both the maximum value and the minimum value of the range are kept greater than the lowest value for the corresponding smoking article to generate an aerosol.

In some embodiments, the maximum value of the auxiliary temperature maintaining range of the heating monomer in the first stage is greater than the maximum value of the auxiliary temperature maintaining range of the heating monomer in other stages.

Among them, since the aerosol generated by the part of the smoking product corresponding to the heating of the 2-N heating element will pass through the part of the smoking product corresponding to the heating element of the first stage, the auxiliary temperature of the heating element of the first stage is kept at the maximum The value is set to be greater than the maximum value of the auxiliary temperature maintenance range of the heating element in other sections, so the heating element in the first section can be kept at a relatively high temperature, even if the aerosol produced by the part of the smoking product corresponding to the heating element in the subsequent section They are all output through the part of the smoking product corresponding to the heating unit in the first stage, and can also achieve the effect of not absorbing or basically not absorbing the aerosol generated by the part of the smoking product corresponding to other heating units, thereby effectively reducing losses.

In some embodiments, the minimum value of the secondary temperature maintenance range is equal for all heating elements.

That is, in some embodiments, the minimum value of the secondary temperature maintenance range is equal for all heating cells. Specifically, the minimum value of the auxiliary temperature maintenance range of all heating elements is the lowest temperature value that makes the part of the smoking article corresponding to each heating element generate aerosol, for example, 220°C.

Please continue to refer to Figure 5. In some embodiments, when i=1, that is, when the i-th stage heating monomer is the first stage heating monomer, the auxiliary temperature maintenance range is 220°C-280°C, that is, greater than Or equal to 220°C and less than or equal to 280°C; when i is a value greater than 1, that is, when the heating monomer in the i-th stage is the heating monomer following the heating monomer in the first stage, the auxiliary temperature maintenance range is 220°C °C-260 °C, that is, greater than or equal to 220 °C and less than or equal to 260 °C.

In some embodiments, the temperature change rate of the heating monomer in the first stage in the first stage is smaller than the temperature change rate of the heating monomer in other stages in the first stage. In particular, the temperature change rate of the heating monomer in the first stage during the period of temperature increase at a temperature change rate greater than 5°C/S in the first stage is smaller than the temperature of the heating monomer in other stages at a temperature greater than 5°C/S Rate of change The rate of temperature change during the period during which the ramp is taking place.

Therefore, since the temperature of the heating monomer in the first stage will drop when it enters the second stage or the third stage, by heating the monomer in other stages at a temperature change rate greater than 5°C/S The temperature change rate in the time period is set to be higher, so that the heating monomer in the subsequent stage can be raised to the corresponding temperature as soon as possible, and at the same time, it can make up for the temperature drop in the previous stage, which leads to the drop in the overall aerosol temperature, and maintain the overall temperature balance. Make the concentration of aerosol uniform.

In some embodiments, when the i+1th stage is the Nth stage, the heating process of the i+1th heating unit includes the first stage and the second stage in sequence.

That is, in some embodiments, when the i+1 heating element is the Nth heating element, that is, the last heating element, the heating process of the i+1 heating element may only include sequentially The first stage and the second stage of . Therefore, in the present application, when only one heating element is included, the heating process of the (i+1)th heating element may also only include the first stage and the second stage performed in sequence.

Among them, since the aforementioned third stage is to maintain the temperature of the part of the smoking product corresponding to the heating unit in the current stage, so as not to absorb the aerosol generated by the part of the smoking product corresponding to the heating unit in the subsequent stage, when the heating unit in the i+1 stage When the body is already the Nth stage, that is, when the last stage of heating the monomer, or when there is only one stage of heating the monomer itself, there is no subsequent stage of heating the monomer. Therefore, the Nth stage of heating the monomer can only include the first stage in sequence. stage and said second stage without including the third stage.

Wherein, the first stage and the second stage of the N-stage heating monomer are controlled in the same manner as the aforementioned first stage and the second stage of the i-stage heating monomer, for details, please refer to the foregoing description.

Among them, in the relationship between the first target temperature or the first temperature range of the first stage heating monomer and other heating monomers, and the second target temperature or second temperature range of the first heating monomer and other heating monomers In relation to the temperature range, the other sections may also include the heating monomer of the Nth section.

For example, the aforementioned "the first target temperature of the heating element in the first stage is greater than or equal to the first target temperature of the heating element in other stages, and the second target temperature of the heating element in the first stage is greater than or equal to that of the heating element in other stages." In the "second target temperature", the other segments include heating monomers in the 2-N segment.

Please refer to FIG. 6 , which is a schematic diagram of the duration range of each stage of each heating unit in an embodiment of the present application.

As shown in FIG. 6, in some embodiments, N=4, that is, the N-stage heating unit includes a first heating unit, a second heating unit, a third heating unit and a fourth heating unit, The duration of the first phase of the first heating unit is 20-40S (that is, greater than or equal to 20S and less than or equal to 40S), and the duration of the first phase of the second heating unit is 15-30S ( That is, greater than or equal to 15S and less than or equal to 30S), the duration of the first stage of the third heating monomer is 10-30S (that is, greater than or equal to 10S and less than or equal to 30S), the fourth heating monomer The duration of the first stage of the first heating element is 10-30S (that is, greater than or equal to 10S and less than or equal to 30S); the duration of the second stage of the first heating monomer is 30-40S (that is, greater than or equal to 30S and less than or equal to 40S), the duration of the second stage of the second heating monomer is 40-70S (that is, greater than or equal to 40S and less than or equal to 70S), the duration of the second stage of the third heating monomer is 40-80S (that is, greater than or equal to 40S and less than or equal to 80S), the duration of the second stage of the fourth heating unit is 40-90S (that is, greater than or equal to 40S and less than or equal to 90S); the first The third stage of heating the monomer to the third heating monomer lasts from the third stage to the end of the whole heating process.

Therefore, by controlling the temperature of each heating element in each stage, and then by controlling the duration of each heating element in each stage, it can effectively ensure that the part of the smoking product corresponding to each heating element can be fully heated, and ensure that all heating elements in the heating process When the aerosol containing nicotine produced by the part of the smoking product corresponding to the heating element in the first stage passes through the aerosol and reaches the aerosol output end through the gas path, the concentration of the aerosol is uniform and stable throughout the heating period. Wherein, since the smoking product needs to be heated during the smoking process of the smoking product, the heating process in this application refers to the smoking process of the smoking product.

Wherein, the temperature ranges of each heating element shown in Figure 5 at each stage, and the duration of each heating element shown in Figure 6 at each stage are some examples, and there may be other ranges and durations .

In some embodiments, in some embodiments, when the heating monomer in the i-th stage is in the second stage or the third stage, controlling the heating monomer in the i+1th stage to generate heat may include: When the i-stage heating monomer is in the late stage of the second stage, the i+1th stage heating monomer is controlled to generate heat.

That is, in some embodiments, the starting moment when the i+1-th heating element generates heat may be the moment when the i-th heating element is in the late stage of the second stage. Therefore, when the heating element in the i-th stage is in the late stage of the second stage, controlling the heating element in the i+1 stage to generate heat can largely make the heating element in the i+1 stage complete the first stage. At this time, the heating of the monomer in the i-th stage can just complete the second stage. Therefore, when the i+1th section heating element is in the second stage, the i-th section heating element is in the third stage, so that the heating elements of the adjacent sections can relatively evenly heat the corresponding part of the smoking product, and The concentration of the output aerosol is relatively stable.

Wherein, the starting moment of heating of the i+1 heating element is the moment when the i heating element is in the late stage of the second stage, and specifically refers to the heating of the i+1 heating element The starting moment of is such that when the i+1th stage heating monomer is heated from the starting moment to the completion of the first stage, the i-th stage heating monomer just completes the second stage.

In some embodiments, the starting moment for the i+1 heating element to generate heat may be the moment when the second stage of the ith heating element ends.

Among them, in this application, "controlling the heating element in the i-th stage to generate heat", "controlling the heating element in the i+1 stage to generate heat", etc., all refer to controlling the active application of electric energy to the heating element so that the The heating unit generates heat.

In some embodiments, during the entire smoking process of the smoking product, the duration of heating of the heating monomer in the first stage is 3.5 minutes (minutes) to 6 minutes, and the end time of heating of the heating monomer in the first stage to the Nth stage is the same .

Please refer to FIG. 7 , which is a flowchart of a heating control method in another embodiment of the present application. As shown in Figure 7, the heating control method may include:

702: According to the preset temperature control data, control to raise the temperature of the heating body to at least a first target temperature within a preset period of time in the first stage, so as to heat the smoking articles contained in the tobacco pipe and generate an aerosol, and make the atomization core ooze out essential oil and atomize the essential oil, and finally generate an aerosol mixed with essential oil, wherein the first target temperature can make the smoking product generate aerosol, and The temperature at which the atomizing core oozes essential oil and atomizes the essential oil.

That is, in some embodiments, the heating control method of the present application can be performed according to preset temperature control data.

Wherein, as shown in Figure 7, the heating control method may also include:

703: Control the heating of the heating body to enter a second stage according to the preset temperature control data; and in the second stage, control the temperature of the heating body from the first A target temperature drops to a second target temperature.

Therefore, since the preset temperature control data defines the target temperature value or target temperature range corresponding to the heating body at each stage during the entire smoking process of the smoking product, and the starting moment when the heating body enters each stage, according to the The preset temperature control data can accurately control the heating speed of the heating body.

Wherein, in the present application, the starting time when the aforementioned heating body enters each stage is the time corresponding to the time counted from the start of smoking the smoking product, and the current time is the counting time from the start of smoking the smoking product . For example, the heating body will enter the first stage when it starts smoking the smoking product. The time is 30S. Therefore, when the counting time counted from the start of smoking the smoking product reaches 30 seconds, it is determined that the starting time of the second stage of heat generation by the heating body is currently reached, so as to control the heating body to start the second stage of heat generation.

Wherein, when the first stage includes a first period and a second period, the preset temperature control data can also define the end time of the first period of the first stage, that is, the start of the second period time. Therefore, the first period of the first stage is the period from the start moment of the first stage to the start moment of the second period of the first stage, and the second period of the first stage is the period of the second period of the first stage. The period from the start time to the start time of the second phase. For example, the aforementioned "controlling the heating body to heat up to a temperature greater than the first target temperature at a temperature change rate greater than 5°C/S during the first period of the first stage; and in the first stage Controlling the heating body to cool down to the first target temperature during the second period may include: controlling the heating body from the start moment of the first stage to the start moment of the second period of the first stage of the heating body The heating body is heated to a temperature greater than the first target temperature at a temperature change rate greater than 5°C/S; during the initial moment of the second period of the first stage to the initial moment of the second stage, the heating is controlled The body is cooled to the first target temperature.

When the second stage includes a first period and a second period, the preset temperature control data may further define the end time of the first period of the second stage, that is, the start time of the second period. Therefore, the first period of the second stage is the period from the start moment of the second stage to the start moment of the second period of the second stage, and the second period of the second stage is the period of the second period of the second stage The period from the start time to the start time of the third phase. For example, the aforementioned "controlling the temperature of the heating body to drop from the first target temperature to the second target temperature during the first period of the second stage; and controlling the temperature during the second period of the second stage The heating body maintains the second target temperature" may include: controlling the temperature of the heating body within the starting time of the second stage of the heating body to the starting time of the second period of the second stage Decreasing from the first target temperature to a second target temperature; and controlling the heating body to maintain the second target temperature during the period from the start of the second period of the second stage to the start of the third stage.

Among them, the method shown in Figure 7, compared with the methods shown in Figure 2 and Figure 3, only further elaborates specifically to control the heating body to generate heat according to the preset temperature control data, and other more specific content can be found in the aforementioned related descriptions .

In some embodiments, the preset temperature control data may be in the form of a table or a curve.

Wherein, when the aerosol generating device 100 includes multiple heating elements, the preset temperature control data can define the target temperature value or target temperature of each heating element at each stage during the entire smoking process of the smoking product. Range, and the starting moment when each heating body enters each stage. For example, the first target temperature value of the i-th heating element in the first stage, the second target temperature value of the i-th heating element in the second stage, and the auxiliary temperature of the i-th heating element in the third stage range, and the initial moment when the heating monomer of the i-th stage enters each stage.

Wherein, the "controlling the electric energy applied to the heating body or the heating unit according to the comparison result, so that the temperature of the heating body or the heating unit reaches the corresponding target temperature in the current stage" may further include: As a result, when the temperature of the heating body or the heating element is higher than the target temperature that the heating body or the heating element needs to reach in the current stage, the control reduces the electric energy applied to the heating body or the heating element or stops applying the electric energy to For the heating body or the heating monomer, when the comparison result shows that the temperature of the heating body or the heating monomer is lower than the target temperature that the heating body or the heating monomer needs to achieve in the current stage, the control increases the temperature applied to the heating body or the heating monomer.

In some embodiments, the aforementioned preset temperature control data can also define the transition temperature of the heating body or the heating monomer at multiple moments in each stage before reaching the final target temperature of the stage.

Among them, since the temperature of the heating body is relatively low when smoking the smoking product, when electric energy is applied to the corresponding heating body to cause the corresponding heating body to heat up, the temperature rise of the heating body needs a process. By defining the heating body or the heating unit The transition temperature of the body at multiple moments before reaching the final target temperature in each stage in each stage, so that the heating rate can be further precisely controlled.

When not inhaled, the essential oil blocks the through hole. When the temperature of the heating body rises to the first target temperature, the essential oil The essential oil in the liquid storage tank can seep into the atomizing channel through the through hole, and then be atomized. Wherein, Fig. 9 schematically shows an example in which the second chamber Q2 is a liquid storage tank, obviously, the first chamber Q1 may also be a liquid storage tank. Wherein, the cooling channel 50 is not shown in FIG. 9 . Wherein, the aforementioned atomizing core 41 is provided with a plurality of through holes through the atomizing core.
