[0002] This application relates to the technical field of aerosols, and specifically to a control method of an aerosol generator and an aerosol generator.

Background Art

[0003] Conventional tobacco products (such as cigarettes, cigars, etc.) generate tobacco smoke by burning tobacco during use. In the prior art, as an alternative to such conventional tobacco products, there are already products that release compounds by heating without combustion. An example of such a product is an aerosol generator, which usually includes a heating assembly for heating a tobacco-shaped aerosol product inserted into the device, whereby a part of the active substances in the aerosol product volatilizes due to heat to generate an aerosol.

[0004] Currently, the above-mentioned aerosol generators usually use batteries for power supply. However, since the discharge performance of the battery is greatly affected by the ambient temperature, when the ambient temperature varies significantly, there is also a large difference in the number of consecutive puffable tobacco-shaped aerosol products.

[0012] The step of selectively determining the corresponding output power according to the temperature and voltage intervals to which it belongs includes supplying a third output power to the heating assembly if the temperature interval to which it belongs is a second ambient temperature interval and the voltage interval to which it belongs is a first voltage interval, and supplying a fourth output power to the heating assembly if the temperature interval to which it belongs is a second ambient temperature interval and the voltage interval to which it belongs is a second voltage interval, wherein the minimum value of the first voltage interval is greater than the maximum value of the second voltage interval and the third output power is greater than the fourth output power.

[0013] The step of selectively determining the corresponding output power according to the temperature and voltage intervals to which it belongs includes supplying a fifth output power to the heating assembly if the temperature interval to which it belongs is a second ambient temperature interval and the voltage interval to which it belongs is a first voltage interval, and supplying a sixth output power to the heating assembly if the temperature interval to which it belongs is a third ambient temperature interval and the voltage interval to which it belongs is a first voltage interval, wherein the minimum value of the second ambient temperature interval is greater than the maximum value of the third ambient temperature interval and the fifth output power is greater than the sixth output power.

However, it goes without saying that the embodiments described below are not all of the embodiments of the present application, but only a selection of them. All other embodiments that those skilled in the art can obtain without creative work based on the embodiments of the present application should also be included in the scope of protection of the present application.

The data used in this manner may be replaced as appropriate for the embodiments of this application described herein. In addition, terms such as “includes” and “has,” and any variations thereof, are intended to cover non-exclusive inclusion, for example, a procedure, method, system, product, or apparatus that includes a series of steps or units may include not only those steps or units explicitly listed, but also other steps or units that are not explicitly listed or that are specific to these procedures, methods, products, or apparatus.

[0021] As described in the background art, aerosol generators usually use batteries for power supply. However, since the discharge performance of the battery is greatly affected by the ambient temperature, when the ambient temperature varies significantly, there is a large difference in the number of consecutive puffable cigarettes of cigarette-shaped aerosol products. In the embodiments of the present application, in order to solve the problems existing in the prior art, a control method for an aerosol generator and an aerosol generator are provided.

[0022] Hereinafter, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the drawings in the embodiments of the present invention.

[0023] FIG. 1 is a block diagram of the hardware configuration of an aerosol generator that executes a control method for an aerosol generator provided according to an embodiment of the present invention. The aerosol generator 100 includes a battery cell 10, a main board 20, and a heating assembly 30. A controller of the aerosol generator 100 is provided on the main board 20. The battery cell 10 and the heating assembly 30 are each electrically connected to the controller. Thereby, the controller can control the battery cell 10 to supply electrical energy to the heating assembly 30. The aerosol generator 100 is further provided with a cavity 40 that extends in the vertical direction. The cavity 40 is for accommodating a cigarette-shaped aerosol product 200 used in combination with the aerosol generator 100. The heating assembly 30 adheres to the outer wall of the cavity 40 and can heat the aerosol product 200 in the cavity 40. A part of the active substance filled in the aerosol product 200 can be volatilized by heat to generate an aerosol, and the user can inhale the aerosol by sucking the aerosol product 200.

[0024] Alternatively, in some embodiments, FIG. 2 is a block diagram of the hardware configuration of another aerosol generator that executes the control method of the aerosol generator provided by an embodiment of the present invention. The aerosol generator 100 may heat the aerosol product 200 by electromagnetic induction heating. The heating assembly 30 extends at least partially into the cavity 40, and the end portion extending into the cavity 40 is configured in a pin shape or a sheet shape, so that it can be smoothly inserted into the aerosol product 200 and heated. A coil 50 is wound around the outer wall of the cavity 40. The battery cell 10 energizes an alternating current through the coil 50. The coil 50 generates a variable magnetic field by the alternating current. This variable magnetic field penetrates the heating assembly 30 and induces eddy currents in the heating assembly 30. The heating assembly 30 generates heat by the eddy current effect and the hysteresis effect, and can heat the aerosol product 200. The aerosol generator 100 usually has a preheating stage and a suction stage. In the preheating stage, the battery cell 10 discharges a large amount of power to the heating assembly 30, and the heating assembly 30 quickly heats the aerosol product 200 to a predetermined temperature to satisfy the condition that aerosol can be generated when the user sucks. In the suction stage, when the user sucks, the temperature of the aerosol product 200 is maintained with relatively small heating power to ensure that aerosol can be generated throughout the user's suction process. In the preheating stage, the power supplied from the battery cell 10 to the heating assembly 30 can be called preheating power.

[0025] The control method of the aerosol generator according to the embodiment of the present application is applied to a controller in the aerosol generator. The aerosol generator includes the above battery cell and heating assembly. The controller is electrically connected to the heating assembly and the battery cell respectively. FIG. 3 is a flowchart of the control method of the aerosol generator according to the embodiment of the present application. FIGS. 1 and 2 are block diagrams of the hardware configuration of the aerosol generator that executes the control method of the aerosol generator provided by the embodiment of the present invention.

[0026] As shown in FIGS. 1 to 3, the following steps are included.

[0027] Step S301: Obtain the ambient temperature near the battery cell.

[0028] Specifically, the battery cell in the cavity of the aerosol generator may be a lithium battery, and a thermistor or other dedicated temperature detection assembly can be used to measure the ambient temperature near the battery cell. Furthermore, the ambient temperature is acquired in real time by the temperature detection assembly, which can be selected from thermocouple temperature sensors, resistance temperature sensors, infrared temperature sensors, etc. When the aerosol generator is powered on, the temperature detection assembly detects the ambient temperature where the aerosol generator is located, obtaining a temperature-measuring analog voltage, and the ambient temperature is obtained by calculating the temperature-measuring analog voltage. The temperature detection assembly needs to detect the ambient temperature at a high frequency to ensure accuracy and timeliness of the ambient temperature. Here, detection at 1 to 5 times per minute is preferable. By detecting the temperature at a high frequency, changes in the ambient temperature near the battery cell can be detected in a timely manner, and corresponding adjustments can be made in a timely manner.

[0029] In this embodiment, the ambient temperature can be calculated using the average of multiple temperatures acquired in real time by a temperature sensing assembly, which may be calculated using two, three, four or more measurement results. To calculate the average, the weight of each continuous measurement can be reduced using an arithmetic or geometric series. In a preferred embodiment, a weighted average is used, and the weighted average is calculated considering the currently measured ambient temperature and the previous weighted average. The weight of the current measurement result is approximately 10-50%, and the corresponding previous weighted average has a weight of approximately 90-50%.

[0030] Step S302: Determine the output power supplied to the heating assembly by the battery cell according to the ambient temperature.

[0031] Step S303: Output power is supplied to the heating assembly so that it reaches a preset preheating temperature, and the output power is also supplied so that the electrical capacity of the battery cell can maintain a preset number of aerosol products.

[0032] Specifically, in the preheating stage, the temperature needs to be raised rapidly to the preheating temperature, so the preheating power is usually large, and therefore the battery cell 10 needs to supply a large output power for preheating. When the output power of the battery cell 10 is large, the discharge capacity of the battery cell 10 decreases rapidly when the aerosol generator 100 is used in a low-temperature environment (e.g., winter) because the output power of the battery cell 10 is large. On the other hand, when the aerosol generator 100 is used in a high-temperature environment (e.g., summer), the decrease in the discharge capacity of the battery cell 10 is gradual. Therefore, the number of aerosol products that the battery cell 10 can maintain heating in a low-temperature environment is clearly less than the number of aerosol products that it can maintain heating in a high-temperature environment.

[0033] For example, in a 30°C environment, the discharge capacity of the battery cell 10 is lost slowly, and after the battery cell 10 is fully charged, it can maintain the heating of 10 aerosol products. On the other hand, in a 0°C environment, even if the battery cell 10 still supplies the same output power for preheating, the discharge capacity of the battery cell 10 decreases rapidly, and the rate of discharge capacity loss of the battery cell 10 is faster than the rate of loss at 30°C. As a result, the number of aerosol products that the battery cell 10 can maintain heating after being fully charged at 0°C may be less than 5. In other words, there is a significant difference in the number of aerosol products that can be continuously smoked in low-temperature and high-temperature environments, even if the battery cell 10 is preheating with the same output power.

[0034] Therefore, by obtaining the ambient temperature around the battery cell 10 using the temperature detection assembly in step S301, it is possible to determine the appropriate output power supplied to the heating assembly 30 by the battery cell 10 according to the obtained ambient temperature. This output power preheats the aerosol product to the preheating temperature, while avoiding a large difference in the number of aerosol products that can be continuously smoked by the battery cell 10 in high-temperature and low-temperature environments due to the rapid decrease in the discharge capacity of the battery cell 10.

[0035] Specifically, in one embodiment, if the ambient temperature obtained in step S301 is low, the output power of the battery cell 10 is reduced, the preheating power in the preheating stage is reduced, and the time of the preheating stage is extended accordingly, thereby allowing the aerosol product to reach the preheating temperature. In this case, since the output power of the battery cell 10 is reduced, a rapid decrease in the discharge capacity of the battery cell 10 can be avoided. On the other hand, if the ambient temperature obtained in step S301 is high, the output power of the battery cell 10 is increased, the preheating power in the preheating stage is further increased, and the time of the preheating stage is shortened accordingly, thereby allowing the aerosol product to be heated to the preheating temperature quickly. In this case, because the ambient temperature is high, even if the preheating power is high, the discharge capacity of the battery cell 10 will not decrease rapidly.

[0036] As shown in Table 1, when the ambient temperature is 0°C, 5°C, or 10°C, the output power of the battery cell 10 is always lower than the output power when the ambient temperature is 30°C. As a result, the preheating power of the aerosol generator at 0°C, 5°C, or 10°C is lower than the preheating power at 30°C.

[0037] Therefore, the embodiment of the present invention provides a control method for an aerosol generator, which first obtains the ambient temperature near the battery cell, then determines the output power supplied to the heating assembly by the battery cell according to the ambient temperature, and finally outputs power to the heating assembly so that the heating assembly reaches a preset preheating temperature, and further ensures that the electrical capacity of the battery cell can maintain a preset number of aerosol products with the output power. The present invention solves the technical problem of a large difference in the number of aerosol products that can be continuously smoked in low-temperature and high-temperature environments in an aerosol generator by adjusting the output power output from the battery cell to the heating assembly according to the ambient temperature near the battery cell and optimizing the output power of the battery cell with respect to the ambient temperature. It also solves the problem that the output power of the battery cell is easily affected by temperature.

[0038] One possible implementation involves determining the output power supplied to the heating assembly by the battery cell, depending on the ambient temperature, and includes the following steps:

[0039] Step S401: Determine the temperature interval to which the ambient temperature belongs.

[0040] Step S402: Determine the corresponding output power according to the temperature interval to which it belongs.

[0041] Because ambient temperature is usually unstable, for control convenience, the ambient temperature is divided into multiple temperature intervals, and one output power is set for preheating the aerosol product for each temperature interval. Depending on the temperature interval, part or all of the output power can be used for preheating.

[0042] In one embodiment, the relationship between ambient temperature and output power can be shown in Table 1, but it should be noted that the relationship in the table is merely illustrative and does not limit the scope of protection of this application.

[0043] [Table 1] Table 1 Correlation between ambient temperature and output power JPEG2026518980000002.jpg25170

[0044] For example, as shown in Table 1, the temperature can be divided into four temperature intervals: 0°C ≤ t < 5°C, 5°C ≤ t < 10°C, 10°C ≤ t < 15°C, and 15°C or higher. In the 0°C ≤ t < 5°C temperature interval, the output power of the battery cell is 20W, and the preheating power during preheating is only 57% of the output power. In the 5°C ≤ t < 10°C temperature interval, the output power of the battery cell is 25W, and the preheating power during preheating reaches 71% of the output power. When the acquired ambient temperature is in the 10°C ≤ t < 15°C interval, the output power of the battery cell is 30W, and the preheating power during preheating reaches 86% of the output power. When the acquired ambient temperature is in the 15°C or higher interval, the output power of the battery cell reaches 35W, and all of this output power can be used for preheating, i.e., the preheating power reaches 100% of the output power.

[0045] By setting multiple temperature intervals, when the acquired ambient temperature falls within a certain temperature interval, the percentage of output power and preheating power corresponding to that temperature interval can be directly obtained, thereby effectively improving the efficiency of adjusting output power according to ambient temperature. Furthermore, since ambient temperature is usually unstable, the actual acquired ambient temperature fluctuates up and down. However, by setting temperature intervals, even if the ambient temperature fluctuates up and down, it will stay within the current temperature interval. As a result, the output power of the battery cell remains constant when the ambient temperature change is not large, and changes in the output power of the battery cell due to fluctuations in ambient temperature can be avoided. The number of temperature intervals is not limited to four; in some other embodiments, the temperature intervals may be divided into more segments, and it is easy to understand that the more segments the temperature intervals are divided into, the more precise the adjustment of output power becomes.

[0046] One possible implementation is that the step of determining the output power corresponding to the temperature interval to which it belongs includes the step of determining the output power corresponding to the temperature interval as the first output power if the temperature interval to which it belongs is the first ambient temperature interval, and determining the output power corresponding to the temperature interval as the second output power if the temperature interval to which it belongs is the second ambient temperature interval.

[0047] The minimum value in the first ambient temperature interval is greater than the maximum value in the second ambient temperature interval, and the first output power is greater than the second output power.

[0048] Specifically, by determining the output power according to the temperature interval, intelligent control of the aerosol generator can be achieved, improving the degree of automation of the aerosol generator, reducing the need for artificial intervention, and improving the heating efficiency and stability of the aerosol generator. By setting different output power based on different temperature intervals, such as setting a large output power when the temperature is high and a small output power when the temperature is low, the output power of the battery cells during the preheating phase of the aerosol generator in low-temperature environments can be optimized, increasing the number of consecutive cigarettes that can be smoked in the aerosol generator in low-temperature environments.

[0049] As one possible implementation, the step of supplying output power to a heating assembly so that the heating assembly reaches a preset preheating temperature includes the step of supplying the heating assembly with a voltage or duty cycle corresponding to the output power so that the heating assembly reaches a preset preheating temperature.

[0050] Specifically, the required preheating temperature for the preheating stage can be reached by adjusting the voltage or duty cycle of the heating assembly according to the magnitude of the output power. By precisely controlling the voltage or duty cycle of the heating assembly, it is possible to effectively avoid the heating assembly becoming too hot or too cold, ensuring the effectiveness and quality of preheating. Furthermore, by adjusting the output power of the heating assembly according to a preset preheating temperature, precise control of the preheating temperature can be achieved.

[0051] In some embodiments, adjusting the voltage or duty cycle of a heating assembly according to the magnitude of the output power can be achieved by controlling the input voltage and operating time of the heating assembly. Since the power output of the heating assembly is affected by the input voltage and operating time, the power output of the heating assembly can be adjusted by controlling the voltage or duty cycle.

[0052] When controlling the power output of a heating assembly by adjusting the voltage, a lower input voltage results in a correspondingly lower power output, and a higher input voltage results in a correspondingly higher power output. In this way, the power output of the heating assembly can be controlled by adjusting the input voltage as needed. When controlling the power output of a heating assembly by adjusting the duty cycle, the ratio of time the heating assembly is powered on and off within a certain period of time is changed. A smaller duty cycle results in a smaller power output, and a larger duty cycle results in a larger power output. In this way, the power output of the heating assembly can be controlled by adjusting the duty cycle as needed.

[0053] In the specific implementation process, there are multiple voltages or duty cycles, each associated with the output power of the battery cell. To determine which voltage or duty cycle to use, the voltage or duty cycle associated with the temperature interval to which the ambient temperature of the battery cell belongs is selected according to the magnitude of the battery cell's output power, thereby determining the final voltage or duty cycle of the heating assembly.

[0054] As one possible implementation, the steps include further including the step of obtaining the current voltage of the battery cell and determining the output power supplied to the heating assembly by the battery cell depending on the ambient temperature, and the step of determining the output power supplied to the heating assembly by the battery cell depending on the ambient temperature and the current voltage.

[0055] Specifically, the battery voltage can be obtained by detecting the voltage of the battery in the cavity of the smoking device using a voltage detection assembly. By comprehensively considering the ambient temperature and changes in the battery cell voltage, the output power of the heating assembly can be adjusted more precisely, improving the stability and efficiency of the heating effect. Furthermore, since the output power of the battery cell can be automatically adjusted in response to changes in ambient temperature and battery cell voltage without requiring artificial intervention, the usability of the aerosol generator is improved.

[0056] For example, as shown in Table 2, under external environmental conditions of 0°C, if the voltage across the battery cell detected by the voltage detection assembly is 4.0V or higher, the output power of the battery cell is 30W; if the voltage across the battery cell detected by the voltage detection assembly is within the range of 3.8V to 4.0V, the output power of the battery cell is 25W; and if the voltage across the battery cell detected by the voltage detection assembly is within the range of 3.0V to 3.8V, the output power of the battery cell is 20W.

[0057] Furthermore, it should be explained that, in order to further improve the efficiency of adjusting the output power, under the same low-temperature environment, the higher the voltage across the battery cell, the greater the proportion of preheating power in the battery cell's output power. For example, as shown in Table 2, under an external environment of 0°C, when the voltage across the battery cell detected by the voltage detection assembly is 4.0V or higher, the proportion of preheating power is 86%. When the voltage across the battery cell detected by the voltage detection assembly is in the range of 3.8V to 4.0V, the proportion of preheating power decreases to 71%, and when the voltage across the battery cell detected by the voltage detection assembly is in the range of 3.0V to 3.8V, the proportion of preheating power decreases further to 57%.

[0058] The correspondence between determining output power based on both ambient temperature and battery cell voltage can be shown in Table 2, but it should be noted that the correspondence in Table 2 is merely illustrative and does not limit the scope of protection of this application.

[0059] [Table 2] Table 2 Correlation between ambient temperature, battery cell voltage, and output power JPEG2026518980000003.jpg64170

[0060] As one possible implementation, the step of determining the output power supplied to a heating assembly by a battery cell, depending on the ambient temperature and current voltage, includes the steps of determining the temperature interval to which the ambient temperature belongs, determining the voltage interval to which the current voltage belongs, and determining the corresponding output power depending on the temperature interval and voltage interval to which they belong.

[0061] Specifically, by determining the output power according to the ambient temperature and current voltage, the aerosol generator can operate optimally when operating in different environments. This improves its efficiency, avoids unnecessary energy consumption, reduces energy consumption and costs, and enhances the user experience.

[0062] For example, as shown in Table 2, the temperature interval can be divided into four intervals: 0°C ≤ t < 5°C, 5°C ≤ t < 10°C, 10°C ≤ t < 15°C, and 15°C or higher. The voltage interval can be divided into three intervals: 3.0V ≤ U < 3.8V, 3.8V ≤ U < 4.0V, and 4.0V or higher.

[0063] By setting multiple temperature and voltage intervals, when the acquired ambient temperature and battery cell voltage fall within a certain temperature and voltage interval, the percentage of output power and preheating power corresponding to that interval can be directly obtained, thereby effectively improving the efficiency of adjusting output power according to ambient temperature and battery cell voltage. Furthermore, since ambient temperature and battery cell voltage are usually unstable, the actual acquired ambient temperature and battery cell voltage fluctuate. Under conditions where temperature and voltage intervals are set to maintain a constant output power of the battery cell, the output power of the battery cell can be kept constant even if the ambient temperature and battery cell voltage fluctuate. In this way, fluctuations in ambient temperature and battery cell voltage can be avoided from affecting the representation of the battery cell's output power. Note that the number of set temperature and voltage intervals is not limited to four and three, but can be set to more depending on the actual situation, and the more intervals set, the more precise the adjustment of output power becomes.

[0064] In one possible implementation, the step of determining the corresponding output power depending on the temperature and voltage intervals to which it belongs includes supplying a third output power to the heating assembly if the temperature interval to which it belongs is a second ambient temperature interval and the voltage interval to which it belongs is a first voltage interval, and supplying a fourth output power to the heating assembly if the temperature interval to which it belongs is a second ambient temperature interval and the voltage interval to which it belongs is a second voltage interval, wherein the minimum value of the first voltage interval is greater than the maximum value of the second voltage interval and the third output power is greater than the fourth output power.

[0065] Specifically, within the same temperature range, the range to which the battery cell voltage belongs can be further determined, and the selection of output power can be refined while taking ambient temperature into consideration, thereby enabling more accurate selection of the optimal output power.

[0066] For example, as shown in Table 2, when the ambient temperature is in the temperature range of 5°C ≤ t < 10°C, if the battery cell voltage is in the voltage range of 3.0V ≤ U < 3.8V, the output power of the corresponding battery cell is 25W, and the preheating power during preheating is only 71% of the output power. If the battery cell voltage is in the voltage range of 3.8V ≤ U < 4.0V, the output power of the battery cell is 30W, and the preheating power during preheating is 86% of the output power. If the battery cell voltage is in the voltage range of 4.0V or higher, the output power of the battery cell is 35W, and all of this output power can be used for preheating, i.e., the preheating power reaches 100% of the output power.

[0067] By further determining the voltage range to which a battery cell belongs within the same temperature interval, the selection of output power can be refined, improving the efficiency of battery use. First, as seen from the data in Table 2, battery cells can select different output powers in different voltage ranges, and the proportion of preheating power in the output power also differs. This means that considering only the ambient temperature may not allow for the achievement of the optimal output power. By considering both the battery cell voltage and ambient temperature simultaneously, the output power can be selected more accurately, resulting in a better representation of the final output power.

[0068] Furthermore, since battery cell charging and use generally have time limitations, the overall efficiency of the process can be improved by enabling greater output power in a shorter time. By selecting the appropriate output power, it is also possible to avoid excessive heat generation in the battery and extend its lifespan. Therefore, in practical applications, by subdividing the selection of output power according to different ambient temperatures and battery cell voltages, the battery's energy can be utilized more effectively, improving its reliability, stability, and service life.

[0069] In one possible implementation, the step of determining the corresponding output power depending on the temperature and voltage intervals to which it belongs includes supplying a fifth output power to the heating assembly if the temperature interval to which it belongs is a second ambient temperature interval and the voltage interval to which it belongs is a first voltage interval, and supplying a sixth output power to the heating assembly if the temperature interval to which it belongs is a third ambient temperature interval and the voltage interval to which it belongs is a first voltage interval, wherein the minimum value of the second ambient temperature interval is greater than the maximum value of the third ambient temperature interval and the fifth output power is greater than the sixth output power.

[0070] Similarly, the temperature range to which a given temperature belongs within the same battery cell's voltage range can be further determined, allowing for a more refined selection of output power while considering the battery cell's voltage. This enables a more accurate selection of the optimal output power.

[0071] For example, as shown in Table 2, when the voltage of the battery cell is in the voltage range of 3.8V ≤ U < 4.0V, and the ambient temperature is in the temperature range of 0℃ ≤ t < 5℃, the output power of the corresponding battery cell is 25W, and the preheating power during preheating is 71% of the output power. When the ambient temperature is in the temperature range of 5℃ ≤ t < 10℃, the output power of the battery cell is 30W, and the preheating power during preheating is 86% of the output power. When the ambient temperature is in the temperature range of 10℃ ≤ t < 15℃, the output power of the battery cell is 35W, and all of this output power can be used for preheating, that is, the preheating power reaches 100% of the output power. Similarly, when the ambient temperature is in the temperature range of 15℃ or higher, the output power of the battery cell is 35W, and the preheating power also reaches 100% of the output power.

[0072] By further determining the temperature range to which a given battery cell belongs within its voltage range, the optimal output power can be selected more accurately, leading to higher battery efficiency. Specifically, by considering the battery cell voltage and then subdividing the output power selection according to different temperature ranges, it is possible to ensure that the best possible battery performance is achieved under current environmental conditions. Compared to considering only ambient temperature or only battery cell voltage, considering both factors simultaneously contributes to more efficient use of the battery cell's energy and resources, improving its stability and reliability. For example, in Table 2, if the battery cell voltage is 3.8V ≤ U < 4.0V, the selected output power is 35W regardless of whether the environment is 10℃ ≤ t < 15℃ or higher than 15℃. This means that selecting output power based solely on temperature may result in wasted battery cell resources.

[0073] By subdividing power distribution to battery cells in different operating environments according to actual application needs, this technology contributes to improving the efficiency and reliability of battery cells. Furthermore, by rationally selecting the output power, problems such as battery cell overheating can be mitigated, extending the battery cell's lifespan. Therefore, subdividing the output power not only improves the performance of battery cells but also reduces their running costs.

[0074] Therefore, by directly obtaining the output power corresponding to the ambient temperature and battery voltage based on the correspondence between ambient temperature, battery voltage, and output power, the efficiency of obtaining output power can be increased.

[0075] Embodiments of the present application further provide a control device for an aerosol generator. The control device for an aerosol generator according to embodiments of the present application can be used to implement the control method for an aerosol generator provided by embodiments of the present application. Such devices are for implementing embodiments and preferred embodiments, and descriptions of those already described are omitted. The term "module" as used below may refer to a combination of software and / or hardware capable of implementing a predetermined function. The devices described in the following embodiments are preferably implemented by software, but can also be implemented by hardware, or a combination of software and hardware, and may be conceived.

[0076] The control device for the aerosol generator provided by the embodiments of this application will be described below.

[0077] Figure 4 is a structural block diagram of the control device for an aerosol generator according to an embodiment of the present invention. As shown in Figure 4, the device comprises a temperature acquisition unit 41, a power determination unit 42, and an output unit 43.

[0078] The temperature acquisition unit 41 is for acquiring the ambient temperature near the battery cell.

[0079] Specifically, the battery cell in the cavity of the aerosol generator may be a lithium battery, and since its internal resistance is affected by temperature, the output power of the battery cell is affected by temperature, and a thermistor or other dedicated temperature sensing assembly can be used to measure the ambient temperature near the battery cell. Furthermore, the ambient temperature is acquired in real time by the temperature sensing assembly, which can be selected from thermocouple temperature sensors, resistance temperature sensors, infrared temperature sensors, etc. When the aerosol generator is powered on, the temperature sensing assembly detects the temperature of the environment in which the aerosol generator is located, thereby obtaining the temperature-measuring analog voltage, and the ambient temperature is obtained by calculating the temperature-measuring analog voltage. The temperature sensing assembly needs to detect the ambient temperature at a high frequency to ensure the accuracy and timeliness of the ambient temperature. Here, detection at 1 to 5 times per minute is preferable. By detecting the temperature at a high frequency, changes in the ambient temperature near the battery cell can be detected in a timely manner, and corresponding adjustments can be made in a timely manner.

[0080] The power determination unit 42 is for determining the output power supplied to the heating assembly by the battery cell according to the ambient temperature.

[0081] Specifically, the performance of a battery cell changes with ambient temperature. Therefore, it is necessary to adjust the output power that the battery cell can supply to the heating assembly according to the ambient temperature so that the continuous smoking time after the battery cell is fully charged is extended. Generally, when the ambient temperature is low, the amount of electricity in the battery cell decreases, and the output power decreases. When the ambient temperature is high, the amount of electricity in the battery cell increases, and the output power increases accordingly. Therefore, it is necessary to adjust the output power of the battery cell according to the change in ambient temperature, which ensures the normal operation of the heating assembly and increases the number of continuous cigarettes that can be smoked in an aerosol generator in low-temperature environments, thus solving the problem in conventional technology where the discharge performance of the battery in aerosol generator is greatly affected by ambient temperature.

[0082] The output unit 43 outputs power to the heating assembly so that the heating assembly reaches a preset preheating temperature, and further, the output power is used to maintain the electrical capacity of the battery cells at a preset number of aerosol products.

[0083] Specifically, by outputting power corresponding to the heating assembly, it is possible to ensure that the heating assembly reaches a preset preheating temperature, thereby ensuring the normal operation of the aerosol generator and satisfying the user's inhalation needs. At the same time, by controlling the electrical capacity of the battery cell, it is possible to ensure that the number of power output cycles of the battery cell matches a preset requirement, thereby extending the battery cell's operating time.

[0084] Therefore, the embodiment of the present invention provides a control device for an aerosol generator, comprising: a temperature acquisition unit for acquiring the ambient temperature near the battery cell; a power determination unit for determining the output power supplied to the heating assembly by the battery cell according to the ambient temperature; and an output unit for outputting output power to the heating assembly so that the heating assembly reaches a preset preheating temperature, and further for ensuring that the electrical capacity of the battery cell can maintain a preset number of aerosol products with the output power. The device solves the problem that the output power of the battery cell is susceptible to temperature changes by adjusting the output power output to the heating assembly by the battery cell according to the ambient temperature near the battery cell and optimizing the output power of the battery cell with respect to the ambient temperature.

[0085] In one possible implementation, the power determination unit includes a first temperature interval determination module and a first output power determination module.

[0086] The first temperature interval determination module is used to determine the temperature interval to which the ambient temperature belongs.

[0087] Specifically, the temperature intervals can be 0°C ≤ t < 5°C, 5°C ≤ t < 10°C, 10°C ≤ t < 15°C, and 15°C or higher. To effectively guarantee the service life of the aerosol generator, for example, in extremely low-temperature environments such as -10°C, a protection circuit can be provided to prevent damage to the battery cells due to prolonged use in low-temperature environments. Furthermore, by setting temperature intervals, the system can be precisely adjusted according to the acquired ambient temperature, improving the efficiency of the adjustment and avoiding inaccurate control due to temperature errors. In addition, different control policies can be set according to different temperature intervals, allowing adaptation to different ambient temperatures.

[0088] The first output power determination module is for determining the corresponding output power according to the temperature interval to which it belongs.

[0089] Specifically, by adjusting the output power according to changes in ambient temperature, excessive or insufficient heating can be avoided. This extends the lifespan of the battery cells and prevents degradation and oxidation of the battery cells due to excessive heating. By improving heating efficiency, reducing energy waste, and extending the usage time of the battery cells in a single operating cycle, the continuous smoking time after the battery cells are fully charged is increased.

[0090] Therefore, based on the correspondence between the temperature range to which the ambient temperature belongs and the output power of the battery cell, the output power of the battery cell corresponding to the ambient temperature can be directly obtained. This increases the efficiency of obtaining output power, enables precise temperature control and energy saving effects, and improves the lifespan and heating efficiency of the battery cell.

[0091] As one possible implementation, the first output power determination module includes a first output power determination submodule and a second output power determination submodule.

[0092] The first output power determination submodule determines the output power corresponding to the temperature interval to which it belongs as the first output power when the interval to which it belongs is the first ambient temperature interval, and the second output power determination submodule determines the output power corresponding to the temperature interval to which it belongs as the second ambient temperature interval as the second output power, where the minimum value of the first ambient temperature interval is greater than the maximum value of the second ambient temperature interval, and the first output power is greater than the second output power.

[0093] Specifically, by determining the output power according to the temperature interval, intelligent control of the aerosol generator can be achieved, improving the degree of automation of the aerosol generator, reducing the need for artificial intervention, and improving the heating efficiency and stability of the aerosol generator. By setting different output power based on different temperature intervals, such as setting a large output power when the temperature is high and a small output power when the temperature is low, the output power of the battery cells during the preheating phase of the aerosol generator in low-temperature environments can be optimized, increasing the number of consecutive cigarettes that can be smoked in the aerosol generator in low-temperature environments.

[0094] In one possible implementation, the output unit includes a supply module. The supply module supplies a voltage or duty cycle corresponding to the output power to the heating assembly so that the heating assembly reaches a preset preheating temperature.

[0095] Specifically, the required preheating temperature for the preheating stage can be reached by adjusting the voltage or duty cycle of the heating assembly according to the magnitude of the output power. By precisely controlling the voltage or duty cycle of the heating assembly, it is possible to effectively avoid the heating assembly becoming too hot or too cold, ensuring the effectiveness and quality of preheating. Furthermore, by adjusting the output power of the heating assembly according to a preset preheating temperature, precise control of the preheating temperature can be achieved.

[0096] In some embodiments, adjusting the voltage or duty cycle of a heating assembly according to the magnitude of the output power can be achieved by controlling the input voltage and operating time of the heating assembly. Since the power output of the heating assembly is affected by the input voltage and operating time, the power output of the heating assembly can be adjusted by controlling the voltage or duty cycle.

[0097] When controlling the power output of a heating assembly by adjusting the voltage, a lower input voltage results in a correspondingly lower power output, and a higher input voltage results in a correspondingly higher power output. In this way, the power output of the heating assembly can be controlled by adjusting the input voltage as needed. When controlling the power output of a heating assembly by adjusting the duty cycle, the ratio of time the heating assembly is powered on and off within a certain period of time is changed. A smaller duty cycle results in a smaller power output, and a larger duty cycle results in a larger power output. In this way, the power output of the heating assembly can be controlled by adjusting the duty cycle as needed.

[0098] In the specific implementation process, there are multiple voltages or duty cycles, each associated with the output power of the battery cell. To determine which voltage or duty cycle to use, the voltage or duty cycle associated with the temperature interval to which the ambient temperature of the battery cell belongs is selected according to the magnitude of the battery cell's output power, thereby determining the final voltage or duty cycle of the heating assembly.

[0099] In one possible implementation, the device further comprises a voltage acquisition unit and a second output power determination module. The voltage acquisition unit is for acquiring the current voltage of the battery cell, and the power determination unit further includes a second output power determination module for determining the output power supplied by the battery cell to the heating assembly, depending on the ambient temperature and the current voltage.

[0100] Specifically, the battery voltage can be obtained by detecting the voltage of the battery in the cavity of the smoking device using a voltage detection assembly. By comprehensively considering the ambient temperature and changes in the battery cell voltage, the output power of the heating assembly can be adjusted more precisely, improving the stability and efficiency of the heating effect. Furthermore, since the output power of the battery cell can be automatically adjusted in response to changes in ambient temperature and battery cell voltage without requiring artificial intervention, the usability of the aerosol generator is improved.

[0101] As one possible implementation, the second output power determination module includes a temperature interval determination submodule, a voltage interval determination submodule, and an output power determination submodule. The temperature interval determination submodule is for determining the temperature interval to which the ambient temperature belongs, the voltage interval determination submodule is for determining the voltage interval to which the current voltage belongs, and the output power determination submodule is for determining the corresponding output power according to the temperature interval and voltage interval to which it belongs.

[0102] Specifically, by determining the output power according to the ambient temperature and current voltage, the aerosol generator can operate optimally when operating in different environments. This improves its efficiency, avoids unnecessary energy consumption, reduces energy consumption and costs, and enhances the user experience.

[0103] In one possible implementation, the output power determination submodule includes a third output power supply submodule and a fourth output power supply submodule.

[0104] The third output power supply submodule is for supplying a third output power to the heating assembly when the temperature interval to which it belongs is the second ambient temperature interval and the voltage interval to which it belongs is the first voltage interval, and the fourth output power supply submodule is for supplying a fourth output power to the heating assembly when the temperature interval to which it belongs is the second ambient temperature interval and the voltage interval to which it belongs is the second voltage interval, provided that the minimum value of the first voltage interval is greater than the maximum value of the second voltage interval and the third output power is greater than the fourth output power.

[0105] Specifically, within the same temperature range, the range to which the battery cell voltage belongs can be further determined, and the selection of output power can be refined while taking ambient temperature into consideration, thereby enabling more accurate selection of the optimal output power.

[0106] In one possible implementation, the output power determination submodule further includes a fifth output power supply submodule and a sixth output power supply submodule.

[0107] The fifth output power supply submodule is for supplying a fifth output power to the heating assembly when the temperature interval to which it belongs is the second ambient temperature interval and the voltage interval to which it belongs is the first voltage interval, and the sixth output power supply submodule is for supplying a sixth output power to the heating assembly when the temperature interval to which it belongs is the third ambient temperature interval and the voltage interval to which it belongs is the first voltage interval, provided that the minimum value of the second ambient temperature interval is greater than the maximum value of the third ambient temperature interval and the fifth output power is greater than the sixth output power.

[0108] Similarly, the temperature range to which a given temperature belongs within the same battery cell's voltage range can be further determined, allowing for a more refined selection of output power while considering the battery cell's voltage. This enables a more accurate selection of the optimal output power.

[0109] The control unit for the aerosol generator includes a processor and memory. A temperature acquisition unit, a power determination unit, and an output unit are all stored in memory as program units, and the processor executes the program units stored in memory to realize the corresponding functions. All modules are located within the same processor. Alternatively, each module may be located within a different processor in any combination.

[0110] The processor includes a kernel, which calls corresponding program units from memory. There may be one or more kernels, and by adjusting kernel parameters, the problem of the battery cell's output power being susceptible to temperature fluctuations can be solved.

The device solves the problem that the output power of a battery cell is susceptible to temperature changes by adjusting the output power output from the battery cell to the heating assembly according to the ambient temperature near the battery cell, thereby optimizing the output power of the battery cell with respect to the ambient temperature.
