[0019] In order to have a clearer understanding of the technical features, objects and effects of the application, the specific embodiments of the application will be described in detail with reference to the drawings.

[0020] It should be noted that the flow chart shown in the drawings is only illustrative, and does not necessarily include all the contents and operations / steps, nor does it necessarily execute in the order described. For example, some operations / steps can be further divided, and some operations / steps can be combined or partially combined, so the actual execution order may be changed according to the actual situation.

[0021] The block diagram shown in the drawings is only a functional entity, which does not necessarily correspond to a physically independent entity. That is, these functional entities can be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0022] As Figure 1 shown, some embodiments of the application disclose an atomization heating control method applied to an electronic atomization device, the electronic atomization device comprising an atomization assembly and a liquid guide assembly, the heating control method comprising the following steps:

[0023] generating a pulse signal in response to the puffing action; the pulse signal comprises alternately arranged first pulse sub-signals and second pulse sub-signals;

[0024] the atomization assembly atomizes the aerosol generating substrate in the liquid guide assembly in response to the pulse signal;

[0025] The first pulse sub-signal is configured to drive the atomization assembly to perform atomization work at a first power to generate aerosol for the user to puff.

[0026] The second pulse sub-signal is configured to drive the atomization assembly to perform non-atomization work at a second power, i.e., the second pulse sub-signal is a non-atomization intermittent period, which is a period of complete or almost complete power-off, during which the atomization work of the atomization assembly is stopped or significantly weakened.

[0027] In the process of the user's single puffing of aerosol, the present application controls the first pulse sub-signal and the second pulse sub-signal to be alternately output, the first pulse sub-signal is configured to drive the atomization assembly to perform atomization work at a first power, and the second pulse sub-signal is configured to drive the atomization assembly to perform non-atomization work at a second power. When the atomization assembly performs non-atomization work at the second power, the liquid guide assembly continues to absorb the liquid aerosol generating substrate, quickly replenishes the atomized liquid aerosol generating substrate, solves the problem that the atomization speed and the liquid replenishment speed may not match, thereby maintaining the continuous saturation and wetness of the liquid guide assembly, avoiding the dryness of the liquid guide assembly, especially during long-term puffing, especially in the later stage of puffing, to ensure that the atomization assembly has sufficient and stable liquid supply during the entire single puffing process, and to ensure that the atomization assembly performs uniform heating, maintains the stability and consistency of the concentration, temperature and aroma release of the aerosol, improves the user experience, and increases the user stickiness.

[0028] In some embodiments, the electronic atomization device further comprises a controller, and the heating control method is applied to the controller, such as an MCU. The MCU has low cost, low energy consumption and high integration. The MCU here is only an example and does not limit the present application. It can also be other.

[0029] In some embodiments, before generating the pulse signal in response to the puffing action, the method further comprises: starting an adaptive micro-pulse atomization mode when a trigger signal of the adaptive micro-pulse atomization mode is detected. A targeted triggering mechanism is added before generating the pulse signal in response to the puffing action, which improves the reliability.

[0030] The trigger signal of the adaptive micro-pulse atomization mode can be an input operation of the user on the electronic atomization device, which has instantaneity and reliability. For example, the input operation is a key input operation (continuous short pressing of 5 times), a touch input operation or a voice input operation, etc.

[0031] The trigger signal of the adaptive micro-pulse atomization mode can also be a trigger signal sent by an application program on the terminal, realizing intelligent interaction. Specifically, as shown in Figure 2 FIG. 6, after the application program of the terminal establishes a communication connection (such as a Bluetooth connection) with the electronic atomization device, the user inputs an instruction on the interface of the application program (such as clicking to start the adaptive micro-pulse atomization mode on the interface of the application program) through touch or through voice input, and then the application program of the terminal sends a trigger signal to the electronic atomization device.

[0032] In some embodiments, the electronic atomization device further comprises a puffing sensor, and the heating control method further comprises:

[0033] When the puffing sensor detects that a puffing action occurs, a pulse signal is generated in response to the puffing action. The puffing sensor has real-time performance and high detection sensitivity, and is used to detect that a puffing action occurs or that a puffing action ends. The puffing sensor can be, for example, an electret condenser microphone or an airflow sensor. The electret condenser microphone and the airflow sensor are merely examples and are not limiting to the present application. Other sensors can also be used.

[0034] In some embodiments, the liquid guide assembly is used to deliver liquid aerosol generating substrate to the atomization assembly. The liquid aerosol generating substrate can be, for example, an atomized liquid made of a flavoring material or an atomized liquid made of leaves and / or stems of a plant. The liquid guide assembly can be, for example, a liquid guide cotton or a porous ceramic body. The liquid guide cotton and the porous ceramic body are merely examples and are not limiting to the present application. Other liquid guide assemblies can also be used.

[0035] In some embodiments, the electronic atomization device further comprises a power driving unit. The power driving unit can receive a precise timing signal from the controller (MCU) and control the application or removal of the pulse signal to the atomization assembly at a high response speed, so as to realize millisecond-level or even sub-millisecond-level precise on-off control. The heating control method further comprises:

[0036] The power driving unit is controlled to apply the pulse signal to the atomization assembly, and the atomization assembly heats and atomizes the aerosol generating substrate in the liquid guide assembly in response to the pulse signal.

[0037] The atomization assembly comprises a heating element. Specifically, the pulse signal is applied to the heating element, and the heating element generates heat by resistance in response to the pulse signal, so as to heat and atomize the liquid aerosol generating substrate. The heating element can be, for example, a heating element made of metal or a heating element made of ceramic. The heating element made of metal and the heating element made of ceramic are merely examples and are not limiting to the present application. Other heating elements can also be used.

[0038] In some embodiments, the first pulse sub-signal and the second pulse sub-signal output alternately are periodic signals at a level of kHz to MHz, which are transmitted by switching the on and off states of the fast switching circuit to achieve fine smooth control of the average power or the average temperature.

[0039] In some embodiments, the duration of the first pulse sub-signal is longer than the duration of the second pulse sub-signal. That is, the first pulse sub-signal is a short first pulse sub-signal, for example, the duration of the first pulse sub-signal is between 50 ms and 500 ms. The duration of the second pulse sub-signal is shorter, for example, the duration of the second pulse sub-signal is between 5 ms and 49 ms, which can be preset to 10 ms. It should be noted that the duration data herein is only an example and is not a limitation on the present application. It can also be other.

[0040] In some embodiments, during the second pulse sub-signal, the liquid guide assembly continues to transport the liquid aerosol generating substrate to the area close to the atomization assembly (specifically, the heating element). Specifically, the liquid guide assembly can use its own capillary action to absorb the liquid aerosol generating substrate and continue to transport the liquid aerosol generating substrate to the area close to the atomization assembly, thereby quickly replenishing the liquid aerosol generating substrate atomized by the previous first pulse sub-signal and preventing the area close to the atomization assembly on the liquid guide assembly from drying out.

[0041] In some embodiments, in order to adapt to different atomization speeds (or vaporization speeds) in real time, the liquid replenishment speed is dynamically matched with the atomization speed to optimize the replenishment of the liquid aerosol generating substrate. Therefore, the heating control method further comprises:

[0042] detecting the real-time puffing state during the single puffing process, specifically by using a puffing sensor to detect the real-time puffing state during the single puffing process;

[0043] dynamically adjusting the frequency of the second pulse sub-signal or the duration of the second pulse sub-signal during the single puffing process according to the real-time puffing state.

[0044] And / or, the electronic atomization device further comprises a liquid storage cavity, which is connected to the liquid guide assembly through a pipeline, and is used to store the liquid aerosol generating substrate. The heating control method further comprises:

[0045] during the single puffing process, obtaining the real-time liquid guide pressure in the channel between the liquid storage cavity and the liquid guide assembly, and dynamically adjusting the frequency of the second pulse sub-signal or the duration of the second pulse sub-signal during the single puffing process according to the real-time liquid guide pressure.

[0046] By adjusting the mechanism in real time, the atomization process can be ensured to match the actual real-time puffing behavior of the user, and a puffing experience that better meets the user's needs can be provided. Meanwhile, the intelligent adjustment based on the real-time state also greatly improves the personalization and intelligence level of the product.

[0047] In some embodiments, the real-time puffing state includes a real-time airflow speed, and the real-time airflow speed can dynamically and accurately reflect the atomization speed under the first preset condition. The frequency of the second pulse sub-signal appearing in a single puffing process or the duration of the second pulse sub-signal is dynamically adjusted according to the real-time airflow speed, including:

[0048] If the real-time airflow speed gradually increases, the frequency of the second pulse sub-signal appearing in a single puffing process or the duration of the second pulse sub-signal is increased, so that the liquid supplementing speed is dynamically increased in the case of an increased atomization speed, and the state of the liquid guide assembly being continuously saturated and wet is maintained.

[0049] If the real-time airflow speed gradually decreases, the frequency of the second pulse sub-signal appearing in a single puffing process or the duration of the second pulse sub-signal is reduced, so that the liquid supplementing speed is dynamically reduced in the case of a decreased atomization speed, and the state of the liquid guide assembly being continuously saturated and wet is maintained while liquid leakage in the liquid guide assembly due to excessive liquid amount is avoided.

[0050] And / or, the real-time puffing state includes a real-time puffing duration. The frequency of the second pulse sub-signal appearing in a single puffing process or the duration of the second pulse sub-signal is dynamically adjusted according to the real-time puffing duration, including:

[0051] If the real-time puffing duration increases, the frequency of the second pulse sub-signal appearing in a single puffing process or the duration of the second pulse sub-signal is increased. Through increasing the frequency of the second pulse sub-signal appearing in a single puffing process or the duration of the second pulse sub-signal, sufficient and stable liquid supply for the atomization assembly in the entire single puffing process can be ensured during a longer puffing time, especially in the latter part of the puffing.

[0052] In some embodiments, the real-time liquid guide pressure can dynamically and accurately reflect the atomization speed under the second preset condition, and the frequency of the second pulse sub-signal appearing in a single puffing process or the duration of the second pulse sub-signal is dynamically adjusted according to the real-time liquid guide pressure, including:

[0053] If the real-time liquid guide pressure gradually increases, the frequency of the second pulse sub-signal appearing in a single puffing process or the duration of the second pulse sub-signal is increased, so that the liquid supplementing speed is dynamically increased in the case of an increased atomization speed, and the state of the liquid guide assembly being continuously saturated and wet is maintained.

[0054] If the real-time liquid guiding pressure gradually decreases, the frequency of the second pulse sub-signal appearing in a single puff or the duration of the second pulse sub-signal is reduced, so that the liquid supplementing speed is dynamically reduced in the case of reduced atomization speed, the state of the liquid guiding assembly being continuously saturated and moist is maintained, and liquid leakage in the liquid guiding assembly due to excessive liquid is avoided.

[0055] In some embodiments, the method further comprises, before the puffing action:

[0056] The frequency of the second pulse sub-signal appearing in a single puff or the duration of the second pulse sub-signal is pre-adjusted according to historical puffing data. Through the historical adjustment mechanism, a liquid aerosol generating substrate supplementing scheme that matches the historical puffing data can be set in advance, providing a puffing experience that better meets the user's needs. At the same time, this intelligent adjustment based on historical puffing data also greatly improves the personalization and intelligence level of the product.

[0057] The historical puffing data includes detailed data of each puffing behavior of the user, including single puff duration, interval duration of at least two consecutive puffs, puff count, single heating duration, puffing negative pressure, puffing air flow rate, and time. The historical puffing data also includes the resistance value of the heating element. According to the historical puffing data, the parameters of the second pulse sub-signal for the next one or more puffs can be pre-adjusted. However, when a puffing action is detected by the puffing sensor, the parameters of the second pulse sub-signal pre-adjusted according to the historical puffing data are only a baseline, which needs to be further adjusted according to at least one of the real-time air flow rate, the real-time puffing duration, and the real-time liquid guiding pressure. Understandably, the at least one can be one, two, or three. For example, the historical puffing data shows that the user usually puffs short, so the baseline second pulse sub-signal has a low frequency in a single puff. However, if the user suddenly puffs long, the system will still quickly increase the frequency of the second pulse sub-signal in the current puff according to the real-time puffing duration.

[0058] In addition, the pre-adjustment can be for a single puff, i.e., the pre-adjustment according to the historical puffing data is required before each puff, or for all subsequent puffs, i.e., the pre-adjustment is permanent.

[0059] In some embodiments, the pre-adjustment of the frequency of the second pulse sub-signal appearing in a single puff or the duration of the second pulse sub-signal according to the historical puffing data comprises:

[0060] According to historical puffing data, a historical average single puff duration is obtained, which can accurately indicate whether the user prefers long puffing. If the historical average single puff duration is greater than or equal to a first preset duration, it indicates that the user prefers long puffing. Therefore, the frequency of the second pulse sub-signal occurring during a single puff or the duration of the second pulse sub-signal is increased in advance, so as to set the liquid aerosol generating substrate replenishment scheme in advance to match long puffing, so as to directly and effectively cope with the liquid replenishment demand caused by the user's preference for long puffing in subsequent actual puffing, and maintain the continuous saturation and wetness of the liquid guide assembly.

[0061] And / or, according to the historical puffing data, the frequency of the second pulse sub-signal occurring during a single puff or the duration of the second pulse sub-signal is adjusted in advance, including:

[0062] According to historical puffing data, an average interval duration of at least two consecutive puffs is obtained, which can accurately indicate whether the user prefers continuous puffing. If the average interval duration of at least two consecutive puffs is less than or equal to a second preset duration, it indicates that the user prefers continuous puffing. This behavior may cause the liquid guide assembly to dry out quickly. Therefore, the frequency of the second pulse sub-signal occurring during a single puff or the duration of the second pulse sub-signal is increased in advance, so as to set the liquid aerosol generating substrate replenishment scheme in advance to match continuous puffing, so as to directly and effectively cope with the liquid replenishment demand caused by the user's preference for continuous puffing in subsequent actual puffing, and maintain the continuous saturation and wetness of the liquid guide assembly. Specifically, the frequency of the second pulse sub-signal occurring during a single puff or the duration of the second pulse sub-signal of at least one puff after the first puff is increased in advance, that is, the second or third puff of continuous puffing is replenished in advance to prevent subsequent dry burning. It can be understood that the at least two times can be two times, three times or any number of times.

[0063] And / or, according to the historical puffing data, the frequency of the second pulse sub-signal occurring during a single puff or the duration of the second pulse sub-signal is adjusted in advance, including:

[0064] According to historical puffing data, the cumulative number of puffs and / or the cumulative heating duration is obtained, which can accurately indicate whether the liquid guide assembly is in an aging stage. If the cumulative number of puffs is greater than or equal to a preset number, and / or if the cumulative heating duration is greater than or equal to a third preset duration, it indicates that the liquid guide assembly is in an aging stage, and its liquid guiding capacity begins to decline. Therefore, the frequency of the second pulse sub-signal occurring during a single puff or the duration of the second pulse sub-signal is increased in advance, so as to set the liquid aerosol generating substrate replenishment scheme in advance to match the aging liquid guide assembly, so as to directly and effectively cope with the liquid replenishment demand caused by the decline in the liquid guiding efficiency of the liquid guide assembly in subsequent actual puffing, and maintain the continuous saturation and wetness of the liquid guide assembly, and delay the taste decay.

[0065] and / or, the frequency of the second pulse sub-signal occurring in a single puff or the duration of the second pulse sub-signal is adjusted in advance according to historical puffing data, including:

[0066] According to historical puffing data, the resistance value of the heating element in the atomization assembly is obtained, which can accurately indicate whether the heating element has carbon deposition. If the resistance value of the heating element increases, it indicates that the heating element has carbon deposition. Therefore, the frequency of the second pulse sub-signal occurring in a single puff or the duration of the second pulse sub-signal is increased in advance, and the user is advised to replace the heating element. Thus, the liquid aerosol generating substrate replenishment scheme matched with the heating element with carbon deposition is set in advance, so as to directly and effectively deal with the liquid replenishment demand caused by the increased resistance value of the heating element in subsequent actual puffs, and maintain the continuous saturation and wetness of the liquid guide assembly.

[0067] and / or, the frequency of the second pulse sub-signal occurring in a single puff or the duration of the second pulse sub-signal is adjusted in advance according to historical puffing data, including:

[0068] According to historical data, it is determined whether there is an abnormal puffing behavior. If there is, the frequency of the second pulse sub-signal occurring in a single puff or the duration of the second pulse sub-signal is increased in advance, so as to set the liquid aerosol generating substrate replenishment scheme matched with the abnormal puffing behavior in advance. Thus, the liquid replenishment demand caused by the abnormal puffing behavior can be directly and effectively dealt with in subsequent actual puffs, and the continuous saturation and wetness of the liquid guide assembly can be maintained. The abnormal puffing behavior is a puffing behavior that is intermittent or jittery, which may lead to uneven liquid guidance.

[0069] Specifically, according to historical data, a puffing negative pressure curve (i.e., a puffing negative pressure time sequence) or an airflow velocity curve (i.e., an airflow velocity time sequence) is obtained. If irregular fluctuations occur multiple times in the curve, causing the curve to be discontinuous and deviating from the ideal smooth puffing curve, it indicates that the user has an intermittent or jittery puffing behavior. Therefore, the frequency of the second pulse sub-signal occurring in a single puff or the duration of the second pulse sub-signal is increased in advance.

[0070] In some embodiments, the frequency of the second pulse sub-signal occurring in a single puff is increased, including: reducing the duration of a single first pulse sub-signal, keeping the duration of the second pulse sub-signal unchanged, i.e., reducing the duration of a single period of the first pulse sub-signal and the second pulse sub-signal, and inserting more second pulse sub-signals in a single puff. For example, the original duration of the first pulse sub-signal is 60 ms, the original duration of the second pulse sub-signal is 10 ms, and the original single period is 70 ms. The duration of the first pulse sub-signal is reduced to 50 ms, and the single period is changed to 60 ms.

[0071] The frequency of the second pulse sub-signal in a single puff is reduced by increasing the duration of the first pulse sub-signal while keeping the duration of the second pulse sub-signal unchanged, i.e. increasing the duration of the first pulse sub-signal and the duration of the second pulse sub-signal in a single cycle. For example, the original duration of the first pulse sub-signal is 60 ms, the original duration of the second pulse sub-signal is 10 ms, and the original single cycle is 70 ms. The duration of the first pulse sub-signal is increased to 70 ms, and the single cycle is changed to 80 ms.

[0072] The duration of the second pulse sub-signal is increased by reducing the duration of the first pulse sub-signal while keeping the sum of the duration of the first pulse sub-signal and the duration of the second pulse sub-signal in a single cycle unchanged, i.e. reducing the duration of the first pulse sub-signal and increasing the proportion of the second pulse sub-signal. For example, the original duration of the first pulse sub-signal is 60 ms, the original duration of the second pulse sub-signal is 10 ms, and the single cycle is 70 ms. The duration of the first pulse sub-signal is reduced to 50 ms, and the duration of the second pulse sub-signal is increased to 20 ms.

[0073] The duration of the second pulse sub-signal is reduced by increasing the duration of the first pulse sub-signal while keeping the sum of the duration of the first pulse sub-signal and the duration of the second pulse sub-signal in a single cycle unchanged, i.e. increasing the duration of the first pulse sub-signal and reducing the proportion of the second pulse sub-signal. For example, the original duration of the first pulse sub-signal is 60 ms, the original duration of the second pulse sub-signal is 10 ms, and the single cycle is 70 ms. The duration of the first pulse sub-signal is increased to 65 ms, and the duration of the second pulse sub-signal is reduced to 5 ms.

[0074] It should be noted that the specific values of the duration of the first pulse sub-signal and the duration of the second pulse sub-signal are only examples and do not limit the present application. Other values are also possible.

[0075] In some embodiments, when the frequency of the second pulse sub-signal in a single puff or the duration of the second pulse sub-signal is increased, the amplitude of the first pulse sub-signal is also increased to increase the first power to compensate for the loss of the total duration of the first pulse sub-signal while ensuring that the device does not dry out.

[0076] In some embodiments, the electronic atomization device can also receive feedback input by the user on the terminal, and then adjust the frequency of the second pulse sub-signal occurring in a single puff or the duration of the second pulse sub-signal according to the user's feedback, thereby improving the interactivity and user experience.
