Patent Description:
An electronic atomization device is a device configured to heat and atomize an aerosol-generating substance to form an aerosol, which is widely applied in fields such as medical care and electronic atomization.

Currently, the electronic atomization device has a single heating manner, which generally heats to a preset temperature by using a constant power. When a preset heating power level is higher, a heating speed may be fast, and problems such as an extremely high temperature and generation of harmful substances may be caused. When the preset heating power level is lower, a problem of a poor reduction degree of an atomizing fragrance may be caused, and a taste consistency of the aerosol formed through the atomization is poorer. Therefore, a heating control method in which the temperature increases fast and being safe is required to resolve a problem that a heating speed and the safety cannot be both ensured in existing technical solutions.

D1 (<CIT>) discloses an electronic smoke apparatus. The electronic smoke apparatus comprises an inhale sensor, a smoke source containing vapor-able smoke flavored substances, an electric heater for heating up the smoke flavored substances, and a power management controller to control power supply to operate the heater; wherein the power management controller is to adaptively supply operating power to the heater according to characteristics of a smoking inhaling event detected at said inhale sensor.

D2 (<CIT>) discloses a method for controlling heating of an aerosol precursor arrangement of an electronic smoking article. An average power is directed from a power source to a heating device arranged to heat the aerosol precursor arrangement and a heating time period commensurately initiated. The average power corresponds to a selected power set point associated with the power source. An actual power directed to the heating device is determined as a product of a voltage at, and a current through, the heating device. The actual power is compared to the average power, and the average power is adjusted to direct the actual power toward the selected power set point. The actual power is periodically determined and compared to the average power, and the average power adjusted toward the selected power set point, until expiration of the heating time period. An associated apparatus and computer program product are also provided.

D3 (<CIT>) discloses vaporizer devices and methods for detecting inhalation through a vaporizer using a heating element. A resistive heater of a vaporizer may function as both a heater and as an anemometer to detect inhalation. Alternatively or additionally, a separate resistive heater may be included in an air path through the vaporizer to detect a user inhaling through the vaporizer. A heating control mechanism utilizes the already existing heating element in an anemometric correlation to when the vaporizer is idle and when it is being used (where being used implies the user is taking a puff/ inhalation on the vaporizer). Using this information, a controller of the vaporizer accordingly controls heating to the vaporizer as required.

A heating control method, an electronic atomization device, and a non-transitory computer-readable storage medium are provided.

A heating control method is set out as in appended claims <NUM> to <NUM>.

An electronic atomization device is set out as in appended claim <NUM>.

A non-transitory computer-readable storage medium is set out as in appended claim <NUM>.

According to the heating control method, the electronic atomization device, and the non-transitory computer-readable storage medium provided in the present disclosure, the heating control method is applied to a heating element of an electronic atomization device. The temperature of the heating element is controlled to increase to the first preset temperature in the first time period, such that an atomizing temperature of the aerosol-generating substance may be reached quickly. The heating element is controlled to keep working under the first preset temperature in the second time period and operate the at least two different power levels in the first time period and/or the second time period, such that the atomizing temperature may be maintained above a boiling point temperature of the aerosol-generating substance and below a generation temperature of a harmful substance. In this way, an atomizing efficiency and a fragrance reduction degree may be improved without an occurrence of a problem that harmful substances such as aldehydes and ketones exceed standards. The temperature of the heating element is then controlled to decrease from the first preset temperature to the second preset temperature in the third time period, to avoid a problem that the temperature of the heating element generally rises due to a heat accumulation performance of the heating element, thereby effectively ensuring the taste consistency of the aerosol formed through the atomization. Meanwhile, a current atomization temperature is controlled to be a safe atomizing temperature to keep safe, so that a possibility of a problem of carbons depositing on a heating surface due to a relatively low atomizing temperature may be reduced, and the safety may be effectively ensured while the temperature is increased fast.

To describe the technical solutions in the present disclosure more clearly, the following briefly describes the accompanying drawings required for describing the embodiments. Apparently, the accompanying drawings in the following descriptions show merely some embodiments of the present disclosure, and a person of ordinary skill in the art may still derive other drawings from these accompanying drawings without creative efforts.

The present disclosure is described in detail below with reference to the accompanying drawings and embodiments.

The applicant researches the temperature-increasing curves of an electronic atomization device at different power levels and the inhaling times of a user changing along with time. As shown in <FIG> is temperature-increasing curves of an existing electronic atomization device at different power levels. When a heating power level is <NUM> W, a thermal equilibrium may be reached in response to heating for <NUM> seconds, and a temperature of the thermal equilibrium maybe <NUM>. When the heating power level is <NUM> W, the thermal equilibrium may be reached in response to heating for <NUM> seconds, and the temperature of the thermal equilibrium may be262 °C. When the heating power level is <NUM> W, the thermal equilibrium may be reached in response to heating for <NUM> seconds, and the temperature of the thermal equilibrium may be <NUM>. When the heating power level is <NUM> W, the thermal equilibrium may be reached in response to heating for <NUM> seconds, and the temperature of the thermal equilibrium temperature may be <NUM>. As can be known, when the heating power level of the electronic atomization device <NUM> is excessively high, a problem of an excessively high temperature and harmful substances such as heavy metals and the aldehydes and the ketones exceeding the standards may be caused. When the heating power level is excessively low, a problem that the poor reduction degree of the atomizing fragrance may be caused. As shown in <FIG> is a curve diagram of inhaling times of a user changing along with time. A number of sampled persons is <NUM>, and inhale times of each person is <NUM>. As can be known from <FIG>, although an inhaling habit of each user varies, the inhaling times of each user is concentrated around <NUM> seconds to <NUM> seconds. Meanwhile, since the inhale habits of users are different, in a process of heating continuously or repeatedly by means of the same mode, differences in changes of temperatures gradually increasing of the heating element <NUM> may be great, leading to a poorer taste consistency of the aerosol formed through the atomization.

Referring to <FIG> is a flowchart of a heating control method according to an embodiment of the present disclosure. In the present embodiment, the heating control method is provided, and the heating control method may be applied to the heating element <NUM> of the electronic atomization device <NUM>. The electronic atomization device <NUM> is configured to heat and atomize an aerosol-generating substance to generate the aerosol, the aerosol-generating substance is a liquid or a solid including components such as flavor materials or effective materials. The effective materials may be nicotine or nicotine salt. The electronic atomization device <NUM> includes an atomizer and a body unit. The atomizer is detachably connected to the body unit. The atomizer is configured to heat and atomizer the aerosol-generating substance when being energized. A power supply assembly is disposed in the body unit, and the atomizer is inserted and connected to an interface of an end of the body unit and connected to the power supply assembly in the body unit, so that the power level is supplied to the atomizer through the power supply assembly. When the atomizer needs to be replaced, the atomizer may be detached and a new atomizer is installed on the body unit to reuse the body unit. Certainly, the electronic atomization device <NUM> further includes other components in the existing electronic atomization device such as a microphone head and a holder, and structures and functions of these components are the same as or similar to those in the related art. For details, reference may be made to the related art, and the details are not repeated herein.

The heating control method includes the following operations.

In an operation S11, the method may include controlling a temperature of the heating element to increase to a first preset temperature in a first time period.

In the first time period, a constant power level may be applied for heating, or at least two different power levels may be applied for heating.

In an embodiment, in the first time period, at least two different power levels are operated for heating, to control the temperature of the heating element <NUM> to increase from an environment temperature to the first preset temperature. A duration of the first time period may be less than or equal to <NUM> seconds, so as to reduce a preheating duration, accelerate heating, and improve an atomizing efficiency. The first preset temperature is greater than or equal to a boiling point temperature of the current aerosol-generating substance and is less than a generating temperature of a harmful substance. For example, a liquid aerosol-generating substance generally includes vegetable glycerine (VG), propylene glycol (PG), and fragrances in different flavors. A boiling point of the PG is around <NUM>, and a boiling point of the VG is around <NUM>. Although a higher temperature is helpful to improving an atomizing amount, when the temperature is excessively high, the aerosol-generating substance may be resolved into the harmful substances such as the aldehydes and the ketones. Therefore, based on a comprehensive consideration, a current heating temperature is controlled to reach the atomizing temperature of the aerosol-generating substance quickly, so as to facilitate atomizing the aerosol-generating substance and reduce the possibility of the problem that the harmful substances such as the aldehydes and the ketones exceed the standards. A setting range of the first preset temperature may be from <NUM> to <NUM>. In some embodiments, the setting range of the first preset temperature may be from <NUM> to <NUM>. It may be understood that, the first preset temperature may be any one of <NUM>, <NUM>, or <NUM> in the foregoing range. Meanwhile, according to a requirement of an actual temperature controlling accuracy, the first preset temperature may alternatively be a range fluctuating within a preset range amplitude. For example, the first preset temperature is <NUM>, but an actual temperature ranges from <NUM> to <NUM>.

In an embodiment, the at least two different power levels are operated sequentially in a descending order for heating. A range of each power level may be from <NUM> W to <NUM> W. In addition, heating durations at the at least two different power levels may be the same or different. It may be understood that, heating sequentially in the descending order of power level may smooth a temperature-increasing curve, so that a temperature of the first time period of a temperature-increasing stage may be transitioned to the first preset temperature smoothly, and an occurrence of the temperature of the heating stage being higher than the first preset temperature nay be reduced.

In an implementation process, three different power level with the same heating durations are operated for heating. In the present embodiment, the operation S11 may adopt any scheme of the following two schemes. Scheme one A1, in the first time period, the heating element <NUM> is controlled to operate at <NUM> W for <NUM> seconds, then operate at <NUM> W for <NUM> seconds, and operate at <NUM> W for <NUM> seconds to increase the temperature from the environment temperature to the first preset temperature. In this implementation scheme, the range of the first preset temperature may be from <NUM> to <NUM>. Scheme two A2, in the first time period, the heating element <NUM> is controlled to operate at <NUM> W for <NUM> seconds, then operate at <NUM> W for <NUM> seconds, and operate at <NUM> W for <NUM> seconds to increase the temperature from the environment temperature to the first preset temperature. In this implementation scheme, the range of the first preset temperature may be from <NUM> to <NUM>.

Certainly, in other embodiments, the first time period may be shorter, so that a constant heating power level may be continuously operated in the first time period for heating. For example, in a scheme three or a scheme four, the heating element <NUM> is controlled to increase the temperature from the environment temperature to the first preset temperature in the first time period. The scheme three A3 is, in the first time period, the heating element <NUM> is controlled to operate at <NUM> W for <NUM> seconds to increase the temperature from the environment temperature to the first preset temperature. The scheme four A4 is, in the first time period, the heating element <NUM> is controlled to operate at <NUM> W for <NUM> seconds to increase the temperature from the environment temperature to the first preset temperature.

In an operation S12, the method may include controlling the heating element to keep working under the first preset temperature in a second time period. The minimum heating power level in the first time period is greater than or equal to the maximum heating power level in the second time period, such that a temperature may be quickly increased in the first time period, and a problem of generating the harmful substances due to an excessively high temperature caused by an excessively high heating power level may be reduced in the second time period. The constant power level or the at least two different power levels may be operated for heating in the second time period. However, the heating element <NUM> is controlled to operate the at least two different power levels in at least one of the first time period and the second time period.

In an embodiment, when the at least two different power levels are operated for heating in the first time period, for example, the operation S11 is performed based on the scheme one A1 or the scheme two A2, in the operation S12, the constant heating power level may be operated for heating to keep working under the first preset temperature. For example, a scheme one B1 or a scheme two B2 is applied for heating in the second time period. The scheme one B <NUM>: the heating element <NUM> is controlled to operate <NUM> W for <NUM> seconds in the second time period to keep working under the first preset temperature. The scheme two B2: the heating element <NUM> is controlled to operate <NUM> W for <NUM> seconds in the second time period to keep working under the first preset temperature.

Certainly, the at least two different power levels are operated for heating in the second time period to control the heating element <NUM> to keep working under the first preset temperature. It should be noted that, in this case, the constant power level may be operated for heating in the first time period. A duration of the second time period may range from <NUM> seconds to <NUM> seconds. The first preset temperature is greater than or equal to the boiling point temperature of the aerosol-generating substance and is less than the generating temperatures of the harmful substances such as the aldehydes and the ketones, so that not only the atomizing efficiency of the electronic atomization device <NUM> can be ensured, the possibility of the problem of the harmful substances exceeding the standards may be also reduced.

When the at least two different power levels are operated for heating in the second time period, in the operation S12, the at least two different power levels are operated for heating circularly and alternately, and the heating durations of the at least two different power levels may be the same or different. A range of each power level in the at least two different power levels in the operation S12 may be from <NUM> W to <NUM> W.

In an embodiment, the heating durations of the at least two different power levels are the same. For example, one of two power levels which are operated circularly and alternately for heating is <NUM> W, the other one of the two power levels is <NUM> W, and the heating durations are <NUM> seconds, <NUM> seconds, or <NUM> seconds. The operation S12 may be performed through any one of the following three schemes. Scheme three B3: the heating element <NUM> is controlled to operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, and the above process is performed alternately and circularly for a preset duration. Scheme four B4: the heating element <NUM> is controlled to operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, and operate <NUM> W for <NUM> seconds, and the above process is performed alternately and circularly for the preset duration. Scheme five B5: the heating element <NUM> is controlled to operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, and the above process is performed alternately and circularly for the preset duration. The preset duration is a duration of the second time period. The preset duration may be a standard inhaling duration of a single inhale of the user, which may be <NUM> seconds. It may be understood that, the at least two different power levels being operated for heating circularly and alternately may better control the heating temperature to be less than the first preset temperature, such that a possibility of generating the harmful substances due to the excessively high temperature may be reduced and an extremely high atomizing efficiency may be ensured.

In another embodiment, the heating durations of the at least two different power levels are different. For example, one of the two power levels which are operated circularly and alternately is <NUM> W, the other of the two power levels is <NUM> W, and the heating durations are <NUM> seconds or <NUM> seconds. The operation S12 may be performed through any one of the following two schemes. scheme six B6: the heating element <NUM> is controlled to operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, and this process is performed alternately and circularly for the preset duration. Scheme seven B7: the heating element <NUM> is controlled to operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, operate <NUM> W for <NUM> seconds, and operate <NUM> W for <NUM> seconds, and this process is performed alternately and circularly for the preset duration.

In an embodiment, the scheme two A2 and the scheme six B6 may be adopted, which can not only improve the atomizing efficiency and the fragrance reduction degree, but also can reduce a problem of the temperature of the heating element <NUM> being excessively high and the harmful substances exceeding the standards.

in an operation S13, the method may include controlling the temperature of the heating element to decrease from the first preset temperature to a second preset temperature in a third time period.

The second preset temperature is lower than the first preset temperature, to reduce a possibility of a problem that the temperature of the heating element <NUM> gradually increases due to the heat accumulation performance of the heating element <NUM>, such that the taste consistency of the aerosol formed through the atomization may be effectively ensured. Meanwhile, the current atomizing temperature is controlled to be a safe atomizing temperature to keep safe, so that the possibility of the problem of the carbons depositing on the heating surface due to the lower atomizing temperature may be reduced. In addition, it is also ensured that the first preset temperature can be quickly reached during a next inhale. A setting range of the second preset temperature may be from <NUM> to <NUM>.

The heating element <NUM> may be controlled to operate the constant power level in the third time period. A power range of the constant heating power level may be from <NUM> W to <NUM> W. In some embodiments, the constant power level may be <NUM> W. A duration range of the third time period may be from <NUM> seconds to <NUM> seconds. In an embodiment, the duration range of the third time period may be <NUM> seconds. The operation S13 may be performed based on a scheme one C1 or a scheme two C2. The scheme one C1 is to operate <NUM> W for <NUM> seconds, and the scheme two C2 is to operate <NUM> W for <NUM> seconds.

A duration that the temperature of the heating element <NUM> decreases from the first preset temperature to the second preset temperature may be less than or equal to <NUM> seconds, such that the problem of the harmful substances such as the aldehydes and the ketones or the heavy metals exceeding the standards due to the temperature being increasing continuously.

In an embodiment, the first time period, the second time period, and the third time period are time periods that are consecutive in time, so that the heating element <NUM> keeps working for atomizing to form the aerosol.

According to the heating control method provided in the present embodiment, the heating element <NUM> is controlled to increase the temperature to the first preset temperature in the first time period, so that the atomizing temperature of the aerosol-generating substrate is quickly reached. The heating element <NUM> is then controlled to keep working under the first preset temperature with the second time period, and the heating element <NUM> is controlled to operate the at least two different power levels in the first time period and/or the second time period. Therefore, the atomizing temperature is maintained above the boiling point of the aerosol-generating substance and below the generating temperatures of the harmful substances such as the aldehydes and the ketones or the heavy metals, such that the occurrence of the problem of the harmful substances such as the aldehydes and the ketones exceeding the standards may be reduced while the atomizing efficiency and the fragrance reduction degree are improved. The temperature of the heating element <NUM> is then controlled to decrease from the first preset temperature to the second preset temperature in the third time period and keep working under the second preset temperature for the preset duration, such that the problem of the temperature of the heating element <NUM> being generally increasing due to the heat accumulation performance of the heating element <NUM>, and the taste consistency of the aerosol formed through the atomization may be ensured. Meanwhile, the current atomizing temperature is controlled to be the safe atomizing temperature to keep the safe, so that the possibility of the problem of the carbons depositing on the heating surface due to the relatively lower atomizing temperature may be reduced. Further, the safety can be effectively ensured while the temperature is increased quickly.

In another embodiment, referring to <FIG> is a flowchart of the heating control method according to another embodiment of the present disclosure. In the present embodiment, another heating control method is provided. A plurality of schemes A1 to An configured to control the heating element <NUM> to operate the at least two different power levels or the constant power level in the first time period, a plurality of schemes B1 to Bn configured to control the heating element <NUM> to operate the at least two different power levels or the constant power level in the second time period, and a plurality of schemes C1 to Cn configured to control the heating element <NUM> to operate the constant power level in the third time period may be stored in the electronic atomization device <NUM>. The plurality of schemes A1 to An may include any one or more of the A1, A2, A3, and A4 involved in the foregoing embodiments. The plurality of schemes B1 to Bn may include any one or more of the B1, B2, B3, B4, B5, B6, and B7 involved in the foregoing embodiments. The plurality of schemes C1 to Cn may include any one or more of the C1 and C2 involved in the foregoing embodiments. It may be understood that, n is a natural number; and n may beset according to a hardware indicator such as an internal memory.

The heating control method includes the following operations S21-S26.

In an operation S21: selecting a scheme from the plurality of schemes A1 to An, a scheme from the plurality of schemes B1 to Bn, and a scheme from the plurality of schemes C1 to Cn to form a heating scheme.

In an implementation process, parameters of the electronic atomization device <NUM> or inhaling habit parameters of the user are obtained. The parameters of the electronic atomization device <NUM> include a parameter of an atomizing substance or a parameter of an atomizer. The scheme of the plurality of schemes A1 to An, the scheme of the plurality of schemes B1 to Bn, and the scheme of the plurality of schemes C1 to Cn are selected based on the parameters of the electronic atomization device <NUM> or the inhaling habit parameters of the user to form the heating scheme. Different power levels are operated for heating in at least one scheme of the schemes selected from the plurality of schemes A1 to An and the plurality of schemes B1 to Bn. The inhaling habit parameters of the user include a single inhaling duration of the user. It is detected that the inhaling habit of the user is that the single inhaling duration is <NUM> seconds. It may be understood that, in this case, a total heating duration of the heating scheme formed by the scheme selected from the plurality of schemes A1 to An, the scheme selected from the plurality of schemes B1 to Bn, and the scheme selected from the plurality of schemes C1 to Cn is <NUM> seconds. In other implementations, the total heating duration may be another inhaling duration of the user, such as <NUM> seconds, <NUM> seconds, or <NUM> seconds.

In an embodiment, four different schemes of A1/A2+B1/B2+C1 and four different schemes A1/A2+B3/B4/B5+C1 are selected to research changes of temperatures of two kinds of ceramics along with a heating duration. For details, reference may be made to <FIG> and Table <NUM>. <FIG> is curve diagram of temperatures change along with a heating duration when two ceramics are heated respectively based on a scheme one (A1+B1+C1) according to an embodiment of the present disclosure. <FIG> is curve diagram of temperatures change along with the heating duration when the two ceramics are heated respectively based on a scheme two (A1+B2+C1) according to an embodiment of the present disclosure. <FIG> is curve diagram of temperatures change along with the heating duration when the two ceramics are heated respectively based on a scheme three (A1+B3+C1) according to an embodiment of the present disclosure. <FIG> is curve diagram of temperatures change along with the heating duration when the two ceramics are heated respectively based on a scheme four (A1+B4+C1) according to an embodiment of the present disclosure. <FIG> is curve diagram of temperatures change along with the heating duration when the two ceramics are heated respectively based on a scheme five (A2+B1+C1) according to an embodiment of the present disclosure. <FIG> is curve diagram of temperatures change along with the heating duration when the two ceramics are heated respectively based on a scheme six (A2+B2+C1) according to an embodiment of the present disclosure. <FIG> is curve diagram of temperatures change along with the heating duration when the two ceramics are heated respectively based on a scheme seven (A2+B3+C1) according to an embodiment of the present disclosure. <FIG> is curve diagram of temperatures change along with the heating duration when the two ceramics are heated respectively based on a scheme eight (A2+B5+C1) according to an embodiment of the present disclosure.

The single inhaling duration is <NUM> seconds. As can be known from Table <NUM>, the maximum temperature in the scheme two A2 is below <NUM>, which is relatively safe. The heating durations are all <NUM> seconds, which meets a requirement of increasing the temperature quickly. Therefore, in an implementation process, the scheme two A2 is adopted in the first time period. In addition, constant temperature stages of the scheme five and the scheme six adopt constant power level, and the scheme seven and the scheme eight adopt pulse power level. In an implementation process, two modes respectively select two schemes to test two samples and with mung bean e-liquid. Detection results may refer to Table <NUM> and Table <NUM>. A power level corresponding to a contrasted group may be <NUM> W.

As can be known from Table <NUM>, the atomizing efficiency of the scheme of the at least two different power levels being operated for heating provided in the present disclosure is improved by <NUM>% to <NUM>% when compared with the scheme of the constant power level of <NUM> W being operated for heating in the contrasted group.

As can be known from Table <NUM>, compared with the constant power level of <NUM> W, the scheme of adopting the at least two different power levels has improvements on aspects such as the vapor amount, the fragrance reduction degree, and the fragrance concentration. In addition, on the whole, performances of indicators of the scheme seven is the best. Therefore, in an implementation process, the scheme seven may be selected to perform a heating control.

It should be noted that, in a test process, after a first inhale, a preset time is required to be waited to completely cool down an atomizer and a second inhale is performed. The preset time may be <NUM> minutes, <NUM> minutes, or <NUM> minutes. As can be known from Table <NUM>, compared with the scheme of operating the constant power level of <NUM> W for heating, the e-liquid frying sound of a cotton-core cartridge is more apparent in a process of increasing the temperature quickly according to the scheme of operating the at least two different power levels. In addition, differences between e-liquid frying sounds of the four schemes from the scheme five to the scheme eight of operating the at least two different power levels are relatively smaller.

In an operation S23, the method may include controlling the heating element to keep working under the first preset temperature in a second time period.

In an operation S24, the method may include controlling the temperature of the heating element to decrease from the first preset temperature to a second preset temperature in a third time period.

The operations S22 to S24 are performed according to the heating scheme formed through selecting in the operation S21. An implementation process is the same as or similar to the implementation process of the operations S11 to S13 according to in a first embodiment, and the same or similar technical effects may be also implemented. For details, reference may be made to the foregoing related descriptions, and details are not described herein again.

In an operation S25, the method may include obtaining working parameters of the electronic atomization device under the heating scheme.

The parameters of the electronic atomization device <NUM> include a parameter of an atomizing substance or a parameter of an atomizer. The atomizing substance may be the liquid or the solid including the components such as the flavor materials or the effective materials, and the effective materials may be the nicotine or the nicotine salt. The parameters of the atomizer may include a current heating power level, a heating duration, or a heating temperature.

In an operation S26, the method may include performing a self-learning based on the working parameters of the electronic atomization device under the heating scheme, to optimize an operation of selecting the scheme from the plurality of schemes A1 to An, the scheme from the plurality of schemes B1 to Bn, and the scheme from the plurality of schemes C1 to Cn to form the heating scheme.

As can be known in combination with the foregoing data, according to the heating control method provided in the embodiments of the present disclosure, the atomizing efficiency may be improved by <NUM>% to <NUM>%, the fragrance reduction degree is also improved apparently, and an e-liquid frying frequency of a universal cotton-core product is increased and the sound of the universal cotton-core product is more apparent.

According to the heating control method provided in the embodiments, the plurality of different schemes are pre-stored in the electronic atomization device <NUM>, so that in a heating process, different schemes may be matched based on different atomizing substances and different atomizers and the heating scheme may be formed by combining these schemes. Therefore, the heating control is performed in different time periods based on the selected schemes, so that an occurrence of a problem of the temperature of the heating element being excessively high the harmful substances exceeding the standards, and the carbons depositing on the heating surface due to the relatively lower atomizing temperature may be reduced while the atomizing efficiency may be ensured. In this way, the safety may be effectively ensured while the temperature is increased quickly. Meanwhile, the taste consistency of the aerosol formed through the atomization may be effectively ensured.
