ATOMIZATION HEATING CONTROL METHOD AND DEVICE, AEROSOL GENERATING DEVICE AND STORAGE MEDIUM

FIELD

This application relates to the field of aerosol vaporization technologies, and in particular, to a vaporization heating control method and apparatus, an aerosol-generation apparatus, and a storage medium.

BACKGROUND

As vaporization technologies develop, e-cigarette technologies emerge. An e-cigarette, also known as a virtual cigarette, or an electronic vaporization apparatus, is used as a substitute for a cigarette and is also used for smoking cessation. The e-cigarette uses a heating element to vaporize e-liquid for inhalation by a user.

After starting to operate, a current e-cigarette generally controls a temperature of the heating element to increase rapidly, so that a vaporization temperature can be quickly reached, and e-liquid starts to be vaporized. In addition, after the vaporization is started, the e-cigarette performs heating at constant power, so that the heating element can perform heating at a relatively stable temperature, and an amount of aerosols generated through the vaporization is relatively uniform.

However, in a current heating method, e-liquid on the heating element that can be heated gradually decreases after continuous heating, and then e-liquid is extracted from a liquid storage cavity to be continuously heated. However, during constant power heating, vapor pressure of an air film on a vaporization surface of the heating element is relatively large, which generates an extrusion effect on e-liquid in a micropore and near the micropore. As a result, e-liquid on the vaporization surface cannot be replenished in time, and continued heating may cause overheating of the vaporization surface, and even local dry burning. Damage to a vaporization assembly is further caused, and cigarette soot, a burnt flavor, and other harmful substances are generated on the heating element, which affects normal use of a user.

SUMMARY

In an embodiment, the present invention provides a vaporization heating control method, applied to an aerosol-generation apparatus having a heater including at least one heating element for heating an aerosol-forming substrate, and a power supply for supplying power to the heating element, the method comprising: controlling the power supplied to the at least one heating element; controlling the at least one heating element to heat to a preset first temperature range at preset first power in a first stage so as to cause the at least one heating element to start to vaporize the aerosol-forming substrate; and controlling heating power of the at least one heating element to fluctuate in a second stage so as to cause a temperature of the at least one heating element to fluctuate within a preset second temperature range.

An aerosol-generation apparatus is provided, including: a heater, including at least one heating element that is configured to heat an aerosol-forming substrate; and applying the vaporization heating control method according to any one of the foregoing embodiments.

In an embodiment, the heating element is a porous ceramic heating element.

Therefore, the heating element can fully replenish the aerosol-forming substrate, thereby preventing local dry burning and reducing generation of carbonized particles.

For ease of understanding this application, this application is described more comprehensively below with reference to the related accompanying drawings. The accompanying drawings show embodiments of this application. However, this application may be implemented in many different forms, and is not limited to the embodiments described in this specification. On the contrary, the embodiments are provided to make the disclosed content of this application more comprehensive.

The terms are only used for distinguishing one technical feature from another technical feature. For example, a first temperature range and a second temperature range are two temperature ranges corresponding to different stages.

In addition, the term “and/or” used in this specification includes any and all combinations of related listed items.

As described in the background, the aerosol vaporization apparatus in the related art has a problem of easy generation of cigarette soot and a burnt flavor. The inventor finds through research that reasons for this problem are that, e-liquid needs to have a certain superheat degree when the e-liquid is heated and vaporized to form an aerosol, while there are many components in the e-liquid, including propylene glycol, glycerol, and flavors and fragrances, a mixture of these components is a non-azeotropic substance, and boiling points of some components thereof are far lower than the superheat degree. However, a constant power heating mode causes some components of the e-liquid to be under an overheating condition for a long time, and a substance in the e-liquid that has a low boiling point undergoes a coking reaction during vaporization of the e-liquid and carbonized particles are generated. Under a continuous operation of the aerosol vaporization apparatus, the carbonized particles continuously accumulate and deteriorate, and the carbonized particles accumulated on the vaporization surface generate a burnt flavor after long-time heating and baking at a high temperature.

Based on the foregoing reasons, this application provides a heating control solution that can reduce generation of cigarette soot and a burnt flavor. In addition, a vaporization amount can be ensured without affecting user experience.

In an embodiment, as shown in FIG. 1, a vaporization heating control method is provided, applied to an aerosol-generation apparatus, where the aerosol-generation apparatus includes: a heater, including at least one heating element that is configured to heat an aerosol-forming substrate; and

a power supply, configured to supply power to the heating element; and the method includes:
controlling the power supplied to the heating element, and performing the following steps:

Step S100. In a first stage, control the heating element to heat to a preset first temperature range at preset first power, to cause the heating element to start to vaporize the aerosol-forming substrate.

The first stage may be a first heating stage during each vaporization heating operation performed by the aerosol-generation apparatus, or a first heating stage of one heating cycle during each vaporization heating operation performed by the aerosol-generation apparatus. The first power needs to use a relatively large power. The heating element, by performing heating at the first power, can quickly reach a vaporization temperature and start vaporization, so that a speed at which the aerosol-generation apparatus starts to generate an aerosol is ensured. The first temperature range is a temperature range in which the aerosol-forming substrate can be vaporized. In an embodiment, a lower limit temperature of the first temperature range is greater than a vaporization critical temperature of the aerosol-form substrate, where the vaporization critical temperature refers to a critical temperature that the aerosol-forming substrate can start to be vaporized.

Step S200. In a second stage, control heating power of the heating element to fluctuate, to cause a temperature of the heating element to fluctuate within a preset second temperature range.

The second stage may be a second heating stage during each vaporization heating operation performed by the aerosol-generation apparatus, or a second heating stage of one heating cycle during each vaporization heating operation performed by the aerosol-generation apparatus. At this stage, the heating power of the heating element is controlled to fluctuate between high power and low power, but the temperature of the heating element needs to be maintained to fluctuate within the second temperature range. That is, by alternately using high and low power, the temperature of the heating element is caused to fluctuate up and down within the second temperature range, and a heating temperature is reduced after heating is performed at a high temperature for a period of time, and high temperature heating is performed again after heating is performed at a low temperature for a period of time. When the heating element performs heating at low power, vapor pressure in an air film can be lowered, so that the aerosol-forming substrate in a ceramic micropore can overcome an acting force of the vapor pressure under an action of capillary force, and supplement e-liquid to a vaporization surface of the heating element. When entering high-power heating in a next time period, sufficient aerosol-forming substrates can be provided for heating, which avoids local dry burning, reduces cigarette soot caused by a continuous high temperature, and avoids a burnt flavor. In addition, since the temperature fluctuates within a certain range, different from intermittent heating, this temperature control method uses a feature that a heating body has a thermal inertia, and when switching is performed between high and low power, the temperature does not drop sharply to a temperature that vaporization is not allowed, thereby ensuring an amount of vapor. FIG. 2 is a power change diagram of performing heating using constant power and using a vaporization temperature control method of this application in an embodiment. FIG. 3 is a temperature change diagram of performing heating using constant power (a curve b) and using a vaporization temperature control method of this application to heat (a curve a) in an embodiment. It can be seen that time that a temperature exceeds 300° C. has reduced nearly by half.

In an embodiment, if the aerosol-forming substrate is e-liquid, due to complex components of the e-liquid, boiling points of different substances are different. For example, boiling points of main substances in some common e-liquid are generally between 189° C. to 300° C. Continuous high-temperature heating causes a substance with a low boiling point to undergo high temperature cracking and generate a harmful substance. In this application, by actively controlling a temperature in a second stage, a temperature of a vaporization surface of the heating element fluctuates within a temperature range, which can not only cause various components in the e-liquid to be boiled and vaporized respectively, but also reduce a reaction degree of the high temperature cracking of the e-liquid, thereby reducing the generation of the harmful substance.

As shown in FIG. 4, overheating and boiling e-liquid forms bubbles, and vapor pressure generated by the bubbles is determined by the temperature of the vaporization surface of the heating element. During low-power heating, a superheat degree of the e-liquid is relatively low, and large bubbles cannot be formed. In this case, the vapor pressure of the bubbles is relatively low, and the e-liquid in a liquid guiding hole of the heating element can supply liquid to the vaporization surface under capillary force. During high-power heating, due to a high temperature of the vaporization surface, the e-liquid is overheating and generates large bubbles. In this case, the vapor pressure of the bubbles is greater than the capillary force, so that the e-liquid in the liquid guiding hole is extruded in a direction toward an e-liquid storage tank. By alternately using high and low power to perform heating, the e-liquid can move continuously, so that it is difficult for carbonized particles to stay and adhere to the vaporization surface of the heating element, thereby reducing accumulation of cigarette soot.

According to the foregoing vaporization heating control method, by controlling the heating element to heat to the preset first temperature range at the first power, the aerosol-forming substrate starts to be vaporized. Then, in the second stage, the heating power of the heating element is controlled to fluctuate, to cause the temperature of the heating element to fluctuate within the second temperature range, so that the heating element can have time to lower the temperature, instead of continuously maintaining a relatively high temperature to perform heating, and vapor pressure of an air film on the heating element is reduced. Therefore, the heating element can fully replenish the aerosol-forming substrate, thereby preventing local dry burning and reducing generation of carbonized particles.

In an embodiment, as shown in FIG. 5, the vaporization heating control method further includes:

Step S300. In a third stage, adjust the heating power of the heating element, to cause the temperature of the heating element to be maintained within a preset third temperature range, where a maximum temperature difference of the third temperature range is smaller than a maximum temperature difference of the second temperature range.

The maximum temperature difference refers to a difference between an upper limit and a lower limit of a temperature range. The maximum temperature difference of the third temperature range is a difference between an upper limit temperature and a lower limit temperature of the third temperature range; and the maximum temperature difference of the second temperature range is a difference between an upper limit temperature and a lower limit temperature of the second temperature range.

The third stage may be a third heating stage during each vaporization heating operation performed by the aerosol-generation apparatus, or a third heating stage of one heating cycle during each vaporization heating operation performed by the aerosol-generation apparatus. In the third stage, the temperature of the heating element is controlled to fluctuate within a relatively small temperature range, to further ensure the amount of vapor generated by the aerosol-generation apparatus. In the third stage, the heating power of the heating element may be constant power or fluctuated power.

In the second stage, to ensure that the heating element can fully and timely replenish e-liquid, it is necessary to ensure that a temperature difference of a temperature fluctuation of the heating element is large enough, so that there is sufficient time for the temperature to rise from a lower temperature to a higher temperature, and various components can be boiled fully. Therefore, a difference between the high and low power of each alternate change of the heating element needs to be controlled to be large enough, and power regulation may be controlled by the preset first power difference. The high power in the heating power of each alternate change may be a fixed power value or a variable power value; and the low power may be a fixed power value or a variable power value, provided that the absolute value of the difference between the heating power of two adjacent fluctuations is greater than the first power difference. For example, first high power is used at time t1, first low power is used at time t2, and second high power is used at time t3. The time t1, the time t2, and the time t3 are three consecutive time periods, where an absolute value of a difference between the first high power and the first low power needs to be greater than the first power difference; and an absolute value of the difference between the first low power and the second high power also needs to be greater than the first power difference.

In the third stage, to ensure an amount of vapor and avoid maintaining overheating for a long time, to cause generation of cigarette soot or the heating element to be unable to replenish e-liquid in time, the heating power of the heating element is controlled to fluctuate at a fluctuation difference lower than that of the second stage. The heating power of the heating element is controlled by the preset second power difference to ensure that the temperature of the heating element changes to a certain extent, but the temperature difference is smaller than that of the second stage.

In an embodiment, as shown in FIG. 6, where steps of the controlling heating power of the heating element to fluctuate in a second stage, to cause a temperature of the heating element to fluctuate within a preset second temperature range include:

Step S210. After the heating element continuously performs heating at the first power for a preset first time, control the heating element to reduce the heating power to preset second power to perform heating.

After the heating element continuously performs heating at the first power for the preset first time, that is, after the first stage, the heating element is controlled to reduce the heating power to the preset second power to perform heating. Since in the first stage, a temperature that allows for vaporization needs to be quickly reached, a value of the first power is relatively high. After the first stage ends, the heating power is reduced, and the second power that is lower than the first power is used for performing heating, thereby reducing the temperature of the heating element, providing time for the heating element to replenish e-liquid, and providing sufficient aerosol-forming substrates for high-power heating in a next time period.

Step S220. After the heating element continuously performs heating at the second power for a preset second time, control the heating element to increase the heating power to preset third power to perform heating.

After the heating element performs heating for the preset second time at the second power, to achieve a fluctuation of the heating power of the heating element in the second stage, the heating power is increased to the third power. The third power is greater than the second power, to cause the heating element to enter a high-temperature heating state and fully vaporize the aerosol-forming substrate.

The second stage may be divided into several time periods according to heating characteristics of different heating elements to control the fluctuation of the heating power, and alternately use high and low power to perform heating. For example, the second stage is divided into N time periods, including n1 to nN time periods. First low power is used in the n1 time period, first high power is used in the n2 time period, second low power is used in the n3 time period, ..., n^th low power is used in the n(N-1) time period, and n^th high power is used in the nN time period. Each time period in the n1 to nN time period may be equal or not equal, or partially equal and partially not equal. Both n and N are natural numbers. By alternately using the high and low power to perform heating, time of high-temperature heating can be shortened, and overheating time of the heating element can be reduced. While ensuring an amount of vapor, generation of cigarette soot is reduced, a burnt flavor is avoided, and local dry burning is avoided. In an embodiment, as shown in FIG. 7, where steps of the controlling heating power of the heating element in a second stage, to cause a temperature of the heating element to fluctuate within a preset second temperature range include:

Step S230. Periodically adjust the heating power of the heating element, to cause the temperature of the heating element to periodically fluctuate within the second temperature range.

The heating power of the heating element is adjusted periodically, that is, the second stage is divided into N time periods. By alternately controlling high power and low power of the heating element to perform heating in the N time periods, the temperature of the heating element is caused to periodically fluctuate within the second temperature range. For example, the N time periods include n1 to nN. First low power is used in the n1 time period, first high power is used in the n2 time period, second low power is used in the n3 time period, ..., n^th low power is used in the n(N-1) time period, and n^th high power is used in the nN time period. Each time period in the n1 to nN time periods is equal, so that the temperature of the heating element periodically fluctuates. A superheat degree of the aerosol-forming substrate changes periodically, which can cause a boiling bubble to increase and shrink intermittently, so that a squeezing effect is formed on the aerosol-forming substrate around a micropore of the heating element, and carbonized particles are not easily attached to a surface of the heating element or blocked in a liquid guiding hole of the heating element.

It should be understood that although steps of the flowcharts in FIG. 1 and FIG. 5 to FIG. 7 are shown sequentially according to arrows, the steps are not necessarily performed according to a sequence indicated by the arrows. Unless otherwise clearly specified in this specification, the steps are performed without any strict sequence limit, and may be performed in other sequences. In addition, at least some steps in FIG. 1 and FIG. 5 to FIG. 7 may include a plurality of steps or a plurality of stages. The steps or the stages are not necessarily performed at the same moment, and instead may be performed at different moments. The steps or the stages are not necessarily performed sequentially, and instead may be performed in turn or alternately with another step or at least some of steps or stages of the another step.
