The present application belongs to the field of electronic atomization technology, and specifically relates to a control method of an aerosol generating device, a control device of an aerosol generating device, an aerosol generating device and a readable storage medium.

Heat Not Burning (HNB) devices are electronic devices that prevent aerosol-generating substrates (treated plant leaf products) from burning even when heated. The heating non-combustion device generates an aerosol by heating the aerosol-generating substrate to a high temperature, but the temperature is insufficient for combustion, so it generates the aerosol required by the user under the premise that the aerosol-generating substrate does not burn.

Heating non-combustion devices currently on the market mainly use the electric resistance heating method, that is, heating is performed by inserting a central heating sheet or heating needle into the inside of the aerosol-generating substrate. These devices require a long waiting time for preheating before use, cannot freely smoke and stop smoking, and the carbonization of the aerosol-generating substrate is not uniform, resulting in insufficient baking of the aerosol-generating substrate and low utilization rate; Next, the HNB device heating sheet is difficult to clean because dirt is easily generated from the aerosol-generating substrate extractor and the heating sheet base; The temperature of the local aerosol-generating substrate in contact with the heating element is excessively high, and some thermal decomposition occurs, releasing substances harmful to the human body. Therefore, microwave heating technology gradually replaced the electric resistance heating method as a new heating method. Microwave heating technology has the characteristics of high efficiency, timeliness, selectivity and no heating delay, and has a heating effect only on materials with specified dielectric properties. Applications using microwave heating atomization have the following advantages. That is, a. Microwave heating is radiation heating, not heat conduction, and can implement immediate suction and immediate interruption; b. Since there is no heated seat, there is no problem with seat breakage or heating seat cleaning; c. The utilization rate of aerosol-generating substrate is high, the taste consistency is high, and the taste is closer to that of cigarettes.

However, the HNB device using microwave heating according to the prior art has a risk of dry heating with an empty cavity, which shortens the service life of the device.

Based on the numerical relationship between the target microwave frequency and the set frequency range, the state of the aerosol-generating substrate inside the atomization chamber can be determined, that is, it can be determined whether the aerosol-generating substrate is accommodated inside the atomization chamber. Again, the operation of the microwave assembly is controlled based on the state of the aerosol-generating substrate inside the atomization chamber. If it is detected that an aerosol-generating substrate is contained inside the atomization chamber, the operation of the microwave assembly is controlled normally to proceed with heating and atomization of the aerosol-generating substrate, and if it is detected that the atomization chamber is in an empty cavity, the microwave is The microwave assembly is controlled and shut down to avoid feeding inward and shortening the service life of the aerosol generating device.

In addition to reducing the atomization effect of the aerosol-generating substrate, it further improves the atomization effect of the aerosol-generating substrate and reduces harmful substances generated because the aerosol-generating substrate is not uniformly heated.

If the aerosol generating substrate is detected to be empty, the atomization chamber is in an empty cavity state. In this case, the microwave assembly is controlled to stop operation to avoid shortening the service life of the aerosol generating device due to the microwave assembly continuously feeding microwaves into the atomization chamber in an empty cavity state.

The microwave assembly is used to feed microwaves into the atomization chamber.

The control method of the aerosol generating device includes the following steps.

Step 102: Control the microwave assembly to perform a frequency sweep operation within the microwave frequency range to query the target microwave frequency within the microwave frequency range;

Step 104: Determining the aerosol generating substrate provision state inside the atomization chamber according to the numerical relationship between the target microwave frequency and the set frequency range;

Step 106: Control the operating state of the microwave assembly based on the provision state of the aerosol-generating substrate.

The control method provided by this embodiment is used to control an aerosol-generating device, and the aerosol-generating device is used to heat an aerosol-generating substrate, wherein the aerosol-generating substrate can be a solid aerosol-generating substrate or a liquid aerosol-generating substrate. there is. An atomization chamber used to accommodate an aerosol-generating substrate is installed inside the aerosol-generating device, and the microwave assembly can feed-in microwaves into the atomizing chamber, and the aerosol-generating substrate is heated under the action of the microwave to achieve atomization. Implement.

It receives the atomization start command and controls the microwave assembly to perform a frequency sweep operation within the microwave frequency range. In detail, the microwave assembly is controlled by each microwave frequency within the microwave frequency range in turn to feed-in the microwave into the atomization chamber. Based on the change in parameters inside the atomization chamber, the target microwave frequency in the microwave frequency range is determined, and the target microwave frequency is the optimal frequency point at which the microwave assembly operates under the current atomization chamber condition, that is, the microwave absorption amount inside the atomization chamber is the greatest. It is a microwave frequency. Based on the numerical relationship between the target microwave frequency and the set frequency range, the state of the aerosol-generating substrate inside the atomization chamber can be determined, that is, it can be determined whether the aerosol-generating substrate is accommodated inside the atomization chamber. Again, the operation of the microwave assembly is controlled based on the state of the aerosol-generating substrate inside the atomization chamber. If it is detected that an aerosol-generating substrate is contained inside the atomization chamber, the operation of the microwave assembly is controlled normally to proceed with heating and atomization of the aerosol-generating substrate, and if it is detected that the atomization chamber is in an empty cavity, the microwave is The microwave assembly is controlled and shut down to avoid feeding inward and shortening the service life of the aerosol generating device. This application determines the target microwave frequency under the current state of the atomization chamber through the frequency sweep operation of the microwave assembly, detects whether the aerosol generating substrate inside the atomization chamber is in place, and microwaves feed into the atomization chamber under the empty cavity state. Increase the service life of aerosol generating devices by avoiding

When the atomization chamber is in an empty cavity state and the aerosol-generating substrate is accommodated inside the atomization chamber, the difference between the target microwave frequencies determined through the frequency sweep is relatively large, so the target microwave frequency and the set frequency range obtained through the frequency sweep The numerical relationship can accurately determine whether the aerosol-generating substrate is contained within the atomization chamber, and this point can be understood.

As shown in FIG. 2, in one of the above embodiments, the step of determining the aerosol generating substrate provision state inside the atomization chamber based on the numerical relationship between the target microwave frequency and the set frequency range includes the following steps in detail: do.

Step 202: Obtain a set frequency range;

Step 204: Determine whether the target microwave frequency is less than the minimum value in the set frequency range, if the judgment result is not, execute step 206, if the judgment result is yes, execute step 212;

Step 206: Determine whether the target microwave frequency is greater than the maximum value in the set frequency range, if the judgment result is not, execute step 208, if the judgment result is yes, execute step 214;

Step 208: Obtaining the average frequency value in the set frequency range;

Step 210: Determine whether the target microwave frequency is greater than the frequency average value, if the judgment result is yes, execute step 214, if the judgment result is not, execute step 212;

Step 212: Determine that the aerosol generating substrate in the atomization chamber is in an empty state, and control the microwave assembly to stop running;

Step 214: It is confirmed that the aerosol-generating substrate in the atomization chamber is in a prepared state, and the microwave assembly is controlled to feed-in the microwave into the atomization chamber according to the target microwave frequency.

In the above embodiment, based on the target microwave frequency being less than the minimum value in the set frequency range, it is determined that the aerosol generating substrate in the atomization chamber is in an empty state;

Based on the fact that the target microwave frequency is greater than the maximum value in the set frequency range, it is determined that the aerosol generating substrate in the atomization chamber is in a provided state;

Based on the fact that the target microwave frequency is within the set frequency range, the state of the aerosol generating substrate inside the atomization chamber is determined based on the numerical relationship between the target microwave frequency and the frequency average value of the set frequency range.

The maximum value in the set frequency range is the optimal frequency point when the aerosol-generating substrate in the atomization chamber is under a filled state, and the minimum value in the set frequency range is when the atomizing chamber is under an empty cavity state, that is, when the aerosol-generating substrate is in an empty cavity state. This is the optimal frequency point when placed under unequipped conditions.

When the target microwave frequency is detected to be less than the minimum value in the set frequency range, it is determined that the atomization chamber is currently in an empty cavity state, that is, the aerosol-generating substrate is not in the atomization chamber.

When the target microwave frequency is detected to be greater than the maximum value in the set frequency range, it is determined that the aerosol-generating substrate inside the atomization chamber is in a prepared state, that is, it is determined that the aerosol-generating substrate is located inside the atomization chamber.

When the target microwave frequency is detected to be within the microwave frequency range, the state of the aerosol generating substrate inside the atomization chamber is further detected based on the numerical relationship between the average value of the microwave frequency range and the target microwave frequency.

By comparing the target microwave frequency with the values within the set frequency range, the accuracy of determining whether aerosol-generating substrate is contained within the atomization chamber is improved. Through the above detection method, it is possible to accurately detect whether an aerosol-generating substrate is contained within the atomization chamber and avoid situations in which microwave heating is performed on an empty atomization chamber due to a misjudgment.

Above all, the optimal frequency point is different when the atomization chamber is placed in an empty cavity state and when the atomization chamber is placed in a state containing an aerosol-generating substrate, wherein the optimal frequency point when the atomization chamber is placed in an empty cavity state is different. The frequency point is a, and the optimal frequency point when the atomization chamber is placed in a state of receiving the aerosol-generating substrate is b. Since the difference between a and b is 25 MHZ to 35 MHZ, the target microwave frequency obtained through the frequency sweep is Typically it is a±2MHZ or b±2MHZ. Therefore, the set frequency range can be set to a to b, and the state of the aerosol generating substrate inside the atomization chamber can be accurately determined based on the numerical relationship between the target microwave frequency and a and b.

The step of determining the state of the aerosol generating substrate inside the atomization chamber based on the numerical relationship between the target microwave frequency and the frequency average value of the set frequency range is detailed,

determining that the aerosol-generating substrate in the atomization chamber is in a prepared state based on the target microwave frequency being greater than the frequency average value;

and determining that the aerosol-generating substrate in the atomization chamber is in an empty state based on the target microwave frequency being less than or equal to the average frequency value.

When it is detected that the target microwave frequency is within the microwave frequency range, the numerical relationship between the target microwave frequency and the average frequency value of the set frequency range is determined, and based on the numerical relationship, the state of the aerosol generating substrate inside the atomization chamber is further determined. judge.

When it is detected that the target microwave frequency is greater than the frequency average value, it is determined that the aerosol-generating substrate in the atomizing chamber is in a prepared state, that is, it is determined that the aerosol-generating substrate is located in the atomizing chamber.

When it is detected that the target microwave frequency is less than or equal to the frequency average value, it is determined that the atomization chamber is currently in an empty cavity state, that is, the aerosol-generating substrate is not in the atomization chamber.

If the target microwave frequency is within the microwave frequency range, the state of the aerosol-generating substrate inside the atomization chamber can be accurately determined by comparing the values of the target microwave frequency and the frequency average value. Through the above detection method, it is possible to accurately detect whether an aerosol-generating substrate is contained within the atomization chamber and avoid situations in which microwave heating is performed on an empty atomization chamber due to a misjudgment.

It would be understandable to set the frequency within the set frequency range before shipping the aerosol generating device. Here, the maximum value in the set frequency range is the optimal frequency value at which the microwave assembly feeds microwaves into the atomization chamber when the atomization chamber contains an aerosol-generating substrate. The minimum value in the set frequency range is the optimal frequency value at which the microwave assembly feeds microwaves into the atomization chamber when the atomization chamber is in an empty cavity state.

In some embodiments, the set frequency range includes a plurality of set frequency values, and is F _1, F _2, . . . in order from smallest to largest. … Arrange as F _n . The formula below:

F _AVG =(F ₁ +F ₂ …+F _n )/n

Here, F _AVG is the frequency average value, F _1, F _2, … … F _n is each frequency value in the set frequency range, and n is the quantity of set frequency values in the set frequency range.

In some other embodiments, the set frequency range includes a plurality of set frequency values, extracts the minimum frequency value and maximum frequency value in the set frequency range, calculates based on the maximum frequency value and minimum frequency value, and calculates the value in the set frequency range. Obtain the frequency average value. The formula below:

F _AVG =(F _min +F _max )/2

Calculate the average value of the frequency range set by,

Here, F _AVG is the frequency average value, F _min is the frequency minimum value, and F _max is the frequency maximum value.

The steps for controlling the running state of the microwave assembly based on the state of the aerosol generating substrate are detailed,

controlling the microwave assembly based on the presence of the aerosol-generating substrate to feed-in the microwave into the atomization chamber at a target microwave frequency;

It includes controlling the microwave assembly to stop operation and output notification information based on the fact that the aerosol generating substrate is in an unequipped state.

In a situation where it is detected that an aerosol-generating substrate is stored inside the atomization chamber because the aerosol-generating substrate is in a prepared state, it is determined that microwave heating atomization can normally be performed on the aerosol-generating substrate, and the microwave assembly is controlled to produce the target microwave. Microwaves are fed into the atomization chamber according to the frequency, where the target microwave frequency is the microwave frequency determined by the microwave assembly through a frequency sweep, and the microwaves of the target microwave frequency are fed into the atomization chamber to achieve atomization. The aerosol generating substrate inside the chamber can be made to reach an optimal atomization state, that is, the aerosol generating substrate has the best microwave absorption effect of the target microwave frequency, which not only reduces the energy consumption of the aerosol generating device. , further improves the atomization effect of the aerosol-generating substrate and reduces harmful substances generated because the aerosol-generating substrate does not receive heat uniformly.

If it is detected that the aerosol-generating substrate is not provided, the atomizing chamber is in an empty cavity state, and the interior of the atomizing chamber is not provided with the aerosol-forming substrate. In this case, the microwave assembly is controlled to stop operation to avoid shortening the service life of the aerosol generating device due to the microwave assembly continuously feeding microwaves into the atomization chamber placed in an empty cavity. In addition, when the atomization chamber is detected to be in an empty cavity state, notification information is output to inform the user to place the aerosol-generating substrate in the atomization chamber, thereby improving the user's feeling of use.

As shown in Figure 3, in any of the above embodiments, the microwave assembly includes a microwave generator and a microwave antenna.

The microwave antenna is interconnected with the microwave generator, and the microwave antenna is used to emit microwaves generated by the microwave generator to the atomization chamber and receive a feedback signal.

The step of controlling the microwave assembly to perform a frequency sweep operation within the microwave frequency range and querying the target microwave frequency within the microwave frequency range includes the following steps in detail.

Step 302: Control the microwave assembly to emit microwaves into the atomization chamber at respective microwave frequencies in the microwave frequency range;

Step 304: Detecting the feedback power value of the feedback signal corresponding to each microwave frequency;

Step 306: Select a target microwave frequency in the microwave frequency range based on the feedback power value corresponding to each microwave frequency.

In the above embodiment, the microwave assembly includes a microwave generator and a microwave antenna, the microwave generator can generate microwaves of a corresponding frequency, and the microwave antenna can feed-in the microwaves of the corresponding frequency into the atomization chamber. You can. After the microwave enters the atomization chamber, the microwave antenna can receive a feedback signal corresponding to the microwave. The microwave assembly further includes a first power detection device and a second power detection device, wherein the first power detection device is interconnected with the microwave generation device and collects the operating power value of the microwave generation device during the operation of the microwave generation device. The second power detection device can be connected to the microwave antenna to detect the feedback power value of the feedback signal received by the microwave antenna.

The microwave assembly is controlled to feed-in microwaves into the atomization chamber according to each microwave frequency within the microwave frequency range. That is, the microwave assembly is controlled to fire microwaves with different microwave frequencies into the atomization chamber in sequence. In the process of emitting microwave waves, the microwave assembly simultaneously receives feedback signals corresponding to each microwave frequency, and determines the feedback power value of each feedback signal through the second power detection device. Based on the measured feedback power value, the target microwave frequency within the microwave frequency range is selected, and the target microwave frequency with the best absorption effect inside the atomization chamber is determined. Through the frequency sweep operation method, microwaves within the microwave frequency range are selected and the target microwave frequency with the best absorption effect inside the current atomization chamber is determined. In a situation where the aerosol-generating substrate is accommodated inside the atomizing chamber, the atomization effect of the aerosol-generating substrate can be improved by feeding microwaves of the target microwave frequency into the atomizing chamber.

First of all, the target microwave frequency is the optimal frequency point at which the microwave assembly feeds microwaves into the current atomization chamber. When the atomization chamber is in an empty cavity state, the detected target microwave frequency is the optimal frequency point at which the microwave assembly outputs microwaves when feeding the microwaves into the empty atomization chamber. When the atomization chamber contains the aerosol-generating substrate, the detected target microwave frequency is the optimal frequency point at which the microwave assembly outputs microwaves when the microwaves are fed into the atomization chamber containing the aerosol-generating substrate.

As shown in Figure 4, in any of the above embodiments, the step of selecting a target microwave frequency in the microwave frequency range based on the feedback power value corresponding to each microwave frequency includes the following steps in detail.

Step 402: Detect the running power value corresponding to each microwave frequency output by the microwave assembly;

Step 404: Obtain a power ratio by calculating the ratio of the feedback power value and the running power value corresponding to each microwave frequency;

Step 406: Select a target microwave frequency in the microwave frequency range based on the power ratio corresponding to each microwave frequency.

In the above design, the operating power value corresponding to each microwave frequency is monitored through the first power detection device. The power ratio can be obtained by calculating the ratio of the driving power value and the corresponding feedback power value. The formula for calculating power ratio is as follows:

N=P ₁ /P ₂ ,

Here, P ₁ is the feedback power value, P ₂ is the running power value, and N is the power ratio.

The smaller the value of N, the better the microwave coupling effect inside the atomization chamber, that is, the better the microwave absorption effect inside the atomization chamber. The larger the value of N, the worse the microwave coupling effect inside the atomization chamber, that is, the worse the microwave absorption effect inside the atomization chamber.

It may be understood that the numerical range of N is less than 1.

In some embodiments, the quantities of microwave frequencies are three, F _a , F _b and F _c , respectively. As a result of the calculation, the power ratio N _a corresponding to F _a is 0.1, the power ratio N _b corresponding to F _b is 0.5, and the power ratio N _c corresponding to F _c is 0.3. N _a , N _b and N _c are arranged in order according to the numerical size, that is, N _a <N _c <N _b , and the smaller the numerical value of the power ratio, the higher the microwave absorption rate, so the microwave assembly is controlled to control the power. It is determined that the best heating effect can be achieved when microwaves are fed into the atomization chamber by the microwave frequency F _a corresponding to the ratio Na, and therefore F _a is the target microwave frequency.

As shown in Figure 5, in one of the above embodiments, the step of selecting a target microwave frequency in the microwave frequency range based on the power ratio corresponding to each microwave frequency includes the following steps in detail.

Step 502: Determining the minimum power ratio among the power ratios corresponding to each microwave frequency;

Step 504: Determine the target microwave frequency by querying the microwave frequency corresponding to the minimum power ratio.

In the above design, the power ratios corresponding to each microwave frequency are arranged according to numerical size, and the operating frequency corresponding to the power ratio with the smallest numerical value is used as the target microwave frequency. By calculating the frequency ratio and filtering the error portion of the frequency sweep step, the accuracy of target microwave frequency selection can be improved, thereby avoiding misjudgment of the target microwave frequency.

As shown in FIG. 6, in one of the above embodiments, the step of selecting a target microwave frequency in the microwave frequency range based on the feedback power value corresponding to each microwave frequency includes the following steps in detail.

Step 602: Determining the minimum feedback power value among the feedback power values corresponding to each microwave frequency;

Step 604: The target microwave frequency is determined by querying the microwave frequency corresponding to the minimum feedback power value.

In the above design, the minimum feedback power value is determined by directly arranging the feedback power values in order according to numerical magnitude. The microwave frequency corresponding to the minimum feedback power value is used as the target microwave frequency.

When the microwave generator outputs microwaves of different frequencies, the change in operating power is relatively small. Therefore, the microwave frequency corresponding to the minimum value of the feedback power is directly selected and used as the target microwave frequency, ensuring the accuracy of target microwave frequency selection. Under the premise that data throughput is reduced, this point can be understood.

The microwave assembly is used to feed-in microwaves to the atomization chamber.

The control method of the aerosol generating device includes the following steps.

Step 702: In response to the operation start command, the microwave assembly is controlled to perform frequency sweep operation according to each microwave frequency;

Step 704: Detecting the feedback power value of the feedback signal corresponding to each microwave frequency during the frequency sweep operation;

Step 706: Select a target microwave frequency in the microwave frequency range based on the feedback power value corresponding to each microwave frequency;

Step 708: Obtain a set frequency range;

Step 710: Determine whether the target microwave frequency is less than the minimum value in the set frequency range, if the judgment result is yes, execute step 718, if the judgment result is not, execute step 712;

Step 712: Determine whether the target microwave frequency is greater than the maximum value within the set frequency range, if the judgment result is yes, execute step 720, otherwise execute step 714;

Step 714: Obtaining the average frequency value within the set frequency range;

Step 716: Determine whether the target microwave frequency is greater than the average frequency value of the set frequency range, if the judgment result is yes, execute step 720, otherwise execute step 718;

Step 718: When the atomization chamber is in an empty cavity state, control the microwave assembly to stop operation;

Step 720: When the aerosol generating substrate is provided in the atomization chamber, the microwave assembly is controlled to feed the microwave into the atomization chamber according to the target microwave frequency.

In the above embodiment, when the aerosol generating device receives the operation start command, the microwave assembly is controlled to perform frequency sweep detection for the atomization chamber to determine the target microwave frequency at which the microwave assembly operates, that is, the microwave assembly is operating under the current state. Determine the optimal frequency point for feeding microwaves into the atomization chamber. During the frequency sweep operation, the microwave assembly is controlled to feed the microwaves into the atomization chamber according to each microwave frequency in turn, and at the same time, the corresponding feedback signal is received to determine the feedback power value of each feedback signal. do.

The feedback power value can reflect the microwave absorption effect of the atomization chamber, the smaller the feedback power value means the stronger the microwave absorption effect of the atomization chamber, the larger the feedback power value, the worse the microwave absorption effect of the atomization chamber.

The inquiry unit 802 receives the atomization start command and controls the microwave assembly to perform a frequency sweep operation within the microwave frequency range. In detail, the microwave assembly is controlled by each microwave frequency within the microwave frequency range in turn to feed-in the microwave into the atomization chamber. Based on the change in the internal parameters of the atomization chamber, the target microwave frequency in the microwave frequency range is determined, and the target microwave frequency is the optimal frequency point at which the microwave assembly operates under the current atomization chamber condition, that is, the microwave absorption amount inside the atomization chamber is the greatest. It is a microwave frequency. The detection unit 804 can determine the state of the aerosol-generating substrate inside the atomization chamber based on the numerical relationship between the target microwave frequency and the set frequency range, that is, determine whether the aerosol-generating substrate is accommodated inside the atomization chamber. You can. The control unit 806 controls the operation of the microwave assembly based on the state of the aerosol-generating substrate inside the atomization chamber. If it is detected that an aerosol-generating substrate is contained inside the atomization chamber, the operation of the microwave assembly is controlled normally to proceed with heating and atomization of the aerosol-generating substrate, and if it is detected that the atomization chamber is in an empty cavity, the microwave is applied to the empty cavity. The microwave assembly is controlled and shut down to avoid shortening the service life of the aerosol generating device due to internal feed-in. This application determines the target microwave frequency under the current state of the atomization chamber through the frequency sweep operation of the microwave assembly, detects whether the aerosol generating substrate inside the atomization chamber is in place, and feeds and cuts microwaves into the atomization chamber under the empty cavity state. Increase the service life of aerosol generating devices by avoiding

When the atomization chamber is in an empty cavity state and the aerosol-generating substrate is accommodated inside the atomization chamber, the difference between the target microwave frequency determined through the frequency sweep is relatively large, so the target microwave frequency and the set frequency range obtained through the frequency sweep are The relationship can be used to accurately determine whether an aerosol-generating substrate is contained within the atomization chamber, and this will be appreciated.

In the above embodiment, the detection unit is also used to determine that the aerosol generating substrate in the atomization chamber is in an empty state based on the target microwave frequency being less than the minimum value in the set frequency range;

The detection unit is also used to determine that the aerosol generating substrate in the atomization chamber is in a prepared state based on the target microwave frequency being greater than the maximum value in the set frequency range;

Based on the fact that the target microwave frequency is within the set frequency range, the detection unit is also used to determine the state of the aerosol generating substrate inside the atomization chamber based on the numerical relationship between the target microwave frequency and the frequency average value of the set frequency range.

In the above embodiment, the maximum value in the set frequency range is the optimal frequency point when the aerosol-generating substrate in the atomization chamber is in an empty state, and the minimum value in the set frequency range is when the atomization chamber is in an empty cavity state, i.e. , is the optimal frequency point when the aerosol-generating substrate is in an unprepared state.

When the target microwave frequency is detected to be less than the minimum value in the set frequency range, it is determined that the atomization chamber is currently in an empty cavity state, that is, the aerosol-generating substrate is not in the atomization chamber.

When the target microwave frequency is detected to be greater than the maximum value in the set frequency range, it is determined that the aerosol-generating substrate inside the atomization chamber is in a prepared state, that is, it is determined that the aerosol-generating substrate is located inside the atomization chamber.

When the target microwave frequency is detected to be in the microwave frequency range, the state of the aerosol generating substrate inside the atomization chamber is further detected based on the numerical relationship between the average value of the microwave frequency range and the target microwave frequency.

By comparing the target microwave frequency with the values within the set frequency range, the accuracy of determining whether the aerosol-generating substrate is contained within the atomization chamber is improved. Through the above detection method, it is possible to accurately detect whether an aerosol-generating substrate is contained within the atomization chamber and avoid situations in which microwave heating is performed on an empty atomization chamber due to a misjudgment.

Above all, the optimal frequency point is different when the atomization chamber is placed in an empty cavity state and when the atomization chamber is placed in a state containing an aerosol-generating substrate, wherein the optimal frequency point is different when the atomization chamber is placed in an empty cavity state. The optimal frequency point is a, and the optimal frequency point when the atomization chamber is placed in a state of receiving the aerosol-generating substrate is b, and since the difference between a and b is 25 MHZ to 35 MHZ, the target microwave frequency obtained through frequency sweep is typically a±2MHZ or b±2MHZ. Therefore, the set frequency range can be set to a to b, and the state of the aerosol generating substrate inside the atomization chamber can be accurately determined based on the numerical relationship between the target microwave frequency and a and b.

In one of the above embodiments, the detection unit is also used to determine that the aerosol-generating substrate in the atomization chamber is in a prepared state based on the target microwave frequency being greater than the frequency average value;

The detection unit is also used to determine that the aerosol-generating substrate in the atomization chamber is in an empty state based on the target microwave frequency being less than or equal to the average frequency value.

In the above embodiment, when it is detected that the target microwave frequency is within the microwave frequency range, the numerical relationship between the target microwave frequency and the average frequency value of the set frequency range is determined, and the aerosol generating substrate inside the atomization chamber is determined based on the numerical relationship. Further determine the state of availability.

When it is detected that the target microwave frequency is greater than the average frequency value, it is determined that the aerosol-generating substrate in the atomizing chamber is in a prepared state, that is, it is determined that the aerosol-generating substrate is located in the atomizing chamber.

When it is detected that the target microwave frequency is less than or equal to the frequency average value, it is determined that the atomization chamber is currently in an empty cavity state, that is, the aerosol-generating substrate is not in the atomization chamber.

If the target microwave frequency is within the microwave frequency range, the status of the aerosol-generating substrate inside the atomization chamber can be accurately determined by comparing the target microwave frequency and the frequency average value. Through the above detection method, it is accurately detected whether the aerosol-generating substrate is accommodated inside the atomization chamber, and further, the accuracy of detecting whether the aerosol-generating substrate is in place is improved, and microwave heating is performed on the empty atomization chamber due to a misjudgment.

The control unit is also used to control the microwave assembly to stop operation and output notification information based on the absence of an aerosol-generating substrate.

In the above example, in a situation where it is detected that the aerosol-generating substrate is in a prepared state and the aerosol-generating substrate is accommodated inside the atomization chamber, at this time, it is determined that microwave heating atomization can normally be performed on the aerosol-generating substrate, and the microwave assembly is controlled to feed-in the microwaves into the atomization chamber according to the target microwave frequency, where the target microwave frequency is the microwave frequency determined by the microwave assembly through a frequency sweep, and the microwaves of the target microwave frequency are fed into the atomization chamber. By feeding, the aerosol-generating substrate inside the atomization chamber can be made to reach the optimal atomization state, that is, the microwave absorption effect of the target microwave frequency can be best achieved in the aerosol-generating substrate, thereby consuming the energy of the aerosol generating device. Not only does it reduce the atomization effect of the aerosol-generating substrate, it also reduces harmful substances generated because the aerosol-generating substrate does not receive heat uniformly.

If it is detected that the aerosol generating substrate is lying empty, the atomization chamber is in an empty cavity state. In this case, the microwave assembly is controlled to stop operation to avoid shortening the service life of the aerosol generating device due to the microwave assembly continuously feeding microwaves into the atomization chamber placed in an empty cavity. In addition, when the atomization chamber is detected to be in an empty cavity state, notification information is output to inform the user to place the aerosol-generating substrate in the atomization chamber, thereby improving the user's feeling of use.

The microwave assembly is controlled to feed-in microwaves into the atomization chamber according to each microwave frequency within the microwave frequency range. That is, the microwave assembly is controlled to fire microwaves with different microwave frequencies into the atomization chamber in sequence. In the process of emitting microwave waves, the microwave assembly simultaneously receives feedback signals corresponding to each microwave frequency, and determines the feedback power value of each feedback signal through the second power detection device. Based on the measured feedback power value, the target microwave frequency within the microwave frequency range is selected, and the target microwave frequency with the best absorption effect inside the atomization chamber is determined. Through the frequency sweep operation method, microwaves within the microwave frequency range are selected and the target microwave frequency with the best absorption effect inside the current atomization chamber is determined. In a situation where the aerosol-generating substrate is accommodated inside the atomizing chamber, the atomization effect of the aerosol-generating substrate can be improved by feeding microwaves of the target microwave frequency into the atomizing chamber.

In one of the above embodiments, the detection unit is also used to detect the operating power value corresponding to the microwave at each microwave frequency output by the microwave assembly;

The inquiry unit is also used to select a target microwave frequency in the microwave frequency range based on the power ratio corresponding to each microwave frequency.

In the above embodiment, the operating power value corresponding to each microwave frequency is monitored through the first power detection device. The power ratio can be obtained by calculating the ratio of the driving power value and the corresponding feedback power value. The formula for calculating power ratio is as follows:

N=P ₁ /P ₂ ,

Here, P ₁ is the feedback power value, P ₂ is the running power value, and N is the power ratio.

The smaller the value of N, the better the microwave coupling effect inside the atomization chamber, that is, the better the microwave absorption effect inside the atomization chamber. The larger the value of N, the worse the microwave coupling effect inside the atomization chamber, that is, the worse the microwave absorption effect inside the atomization chamber.

In one of the above embodiments, the inquiry unit is also used to determine the minimum power ratio among the power ratios corresponding to each microwave frequency; The query unit is also used to determine the target microwave frequency by querying the microwave frequency corresponding to the minimum power ratio.

In the above embodiment, the power ratios corresponding to each microwave frequency are arranged in numerical order, and the operating frequency corresponding to the power ratio with the smallest numerical value is used as the target microwave frequency. By calculating the frequency ratio and filtering the error portion of the frequency sweep step, the accuracy of target microwave frequency selection can be improved, thereby avoiding misjudgment of the target microwave frequency.

In one of the above embodiments, the inquiry unit is also used to determine the minimum feedback power value among the feedback power values corresponding to each microwave frequency; The query unit is also used to determine the target microwave frequency by querying the microwave frequency corresponding to the minimum feedback power value. In the above embodiment, the minimum feedback power value is determined by directly arranging the feedback power values in order according to numerical magnitude. The microwave frequency corresponding to the minimum feedback power value is used as the target microwave frequency.

When the microwave generator outputs microwaves of different frequencies, the change in operating power is relatively small. Therefore, the microwave frequency corresponding to the minimum value of the feedback power is directly selected and used as the target microwave frequency, ensuring the accuracy of target microwave frequency selection. Under the premise that data throughput is reduced, this point can be understood.
