Description

Technical Field

[0001] This application belongs to the field of electronic atomization technology, and specifically relates to an aerosol generating device, a control method, a control device, and a readable storage medium. Background Technology

[0002] A heat-not-burning (HNB) device is a combination of a heating device and an aerosol-generating substrate (treated plant leaf products). The external heating device heats the aerosol-generating substrate to a temperature that allows it to produce aerosols but not enough to burn them, enabling the substrate to generate the aerosols needed by the user without combustion.

[0003] Currently, most heated non-combustible (HNB) appliances on the market use resistance heating, which involves inserting a central heating element or heating needle into the aerosol-generating matrix to heat it. These appliances require long preheating times, cannot be freely stopped or withdrawn, and suffer from uneven carbonization of the aerosol-generating matrix, resulting in insufficient baking and low utilization. Furthermore, the heating element in HNB appliances is prone to accumulating dirt in the aerosol-generating matrix extractor and heating element base, making cleaning difficult. This can cause excessively high temperatures in the localized areas of the aerosol-generating matrix in contact with the heating element, leading to partial decomposition and the release of harmful substances. Therefore, microwave heating technology is gradually replacing resistance heating as the new heating method. Microwave heating technology is characterized by high efficiency, timeliness, selectivity, and no heating delay, and it is effective only for materials with specific dielectric properties. The advantages of using microwave heating atomization are: a) Microwave heating is radiant heating, not heat conduction, allowing for immediate vaping and stopping; b) There is no heating element, so there are no issues with broken elements or cleaning the heating element; c) The aerosol matrix has high utilization rate, high consistency in taste, and a taste closer to that of cigarettes.

[0004] In existing technologies, the determination of whether a microwave component is operating at the optimal frequency point is based on the collected standing wave ratio. This process requires reducing the operating power of the microwave component, which affects the heating and atomization efficiency. Summary of the Invention

[0005] This application aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] In view of this, in a first aspect, embodiments of this application propose an aerosol generating device, comprising: an atomizing cavity; a microwave assembly; a circulator, a first end of which is connected to the microwave assembly, and a second end of which is used to feed microwaves into the atomizing cavity and receive microwaves reflected from the atomizing cavity; a phase detector, the signal input end of which is connected to the first end and the third end of the circulator; and a controller, which is connected to the signal output end of the phase detector, and is used to receive a voltage signal output by the phase detector when the microwave assembly is in operation; and to adjust the microwave frequency of the microwaves output by the microwave assembly according to the voltage signal.

[0007] The aerosol generating device provided in this application includes: an atomizing chamber, a microwave component, a circulator, a phase detector, and a controller. The atomizing chamber is disposed within the housing of the aerosol generating device. The atomizing chamber contains an aerosol generating matrix, which is atomized within the atomizing chamber by microwaves. The microwave component is disposed within the housing, and can be optionally disposed outside or inside the housing. The circulator is mounted outside the atomizing chamber. The microwave output terminal of the microwave component is connected to the first terminal of the circulator, and the second terminal of the circulator is connected to the atomizing chamber. The microwaves output by the microwave component are fed into the atomizing chamber through the first and second terminals of the circulator. The aerosol generating matrix within the atomizing chamber is heated under the action of microwaves, releasing aerosols. The second terminal of the circulator is connected to the atomizing chamber via a coaxial cable to feed microwaves into the atomizing chamber. The second end of the circulator can also receive microwave signals fed back from the atomizing cavity and transmit these signals to the third end of the circulator. Both the first and third ends of the circulator are connected to a phase detector. The phase detector can receive the microwave signals sent from the first and third ends of the circulator and calculate the phase difference between the two signals. It then transmits the voltage signal related to the phase difference to the controller. The controller determines whether the microwaves fed into the atomizing cavity are at the optimal frequency based on the received voltage signal. If the controller determines that the microwaves are not at the optimal frequency, it adjusts the microwave frequency output by the microwave component to the optimal frequency. Specifically, the phase detector continuously receives microwave signals transmitted from the first and third ends of the circulator. A first microwave signal is transmitted to the phase detector through the first end of the circulator, and a second microwave signal is transmitted to the phase detector through the second end of the circulator. The phase detector automatically detects the phase difference between the first and second microwave signals and outputs a voltage signal to the controller based on the detected phase difference. The controller can determine whether the microwave component is currently operating at the optimal frequency point by comparing the voltage value of the voltage signal with the preset voltage value. If it is not operating at the optimal frequency point, the controller will adjust the microwave frequency of the output microwave.

[0008] Among them, a circulator is a device for unidirectional circular transmission of electromagnetic waves. The conduction direction of the signal in the circulator is from the first end to the second end, from the second end to the third end, and from the third end to the first end.

[0009] For example, the phase detector is selected as the AD8302 phase detector. When the phase difference between the first microwave signal and the second microwave signal is detected to be 0°, the output voltage signal value is 1.8V. The larger the phase difference between the first microwave signal and the second microwave signal, the smaller the output voltage signal value. The phase detector can continuously detect the phase difference between the two microwave signals and continuously send the corresponding voltage signal to the controller.

[0010] In related technologies, during the microwave heating of the aerosol generating matrix by controlling the operation of the microwave components in an aerosol generating device, the resonant frequency within the atomization cavity continuously changes as the aerosol generating matrix gradually atomizes. Therefore, after the aerosol generating device has been running for a period of time, it is necessary to re-scan the frequency of the aerosol generating device to find a new optimal frequency point. Since existing technologies determine whether the current microwave frequency is at the optimal frequency point based on the standing wave ratio (VSWR), the operating power of the microwave components needs to be reduced during the frequency scanning process.

[0011] In this embodiment, the first and third ends of the circulator are connected to a phase detector. The phase detector detects whether the current frequency is at the optimal point based on the phase difference of the waveform of the acquired microwave signal, and controls the microwave component to adjust the microwave frequency of the output microwave based on the detection result. This achieves the goal of not reducing the output power of the microwave component during the microwave frequency adjustment process, thereby improving the heating and atomization efficiency of the aerosol generating device for the aerosol generating matrix.

[0012] In addition, the aerosol generating device according to the above-described technical solution provided in this application may also have the following additional technical features:

[0013] In one possible design, the aerosol generating device further includes: a first coupler connected between a first end of the circulator and the signal input terminal of the phase detector; and a second coupler connected between a third end of the circulator and the signal input terminal of the phase detector.

[0014] In this design, the aerosol generating device also includes a first coupler and a second coupler. The first coupler and the second coupler are respectively located at the first and third ends of the circulator, and both are connected to a phase detector.

[0015] The first coupler transmits the first microwave signal fed into the atomizing cavity by the microwave component to the phase detector, and the second coupler transmits the second microwave signal reflected from the atomizing cavity to the phase detector. The phase detector determines the phase difference between the first and second microwave signals by comparing their waveforms, and then transmits the corresponding voltage signal to the controller.

[0016] This application embodiment achieves the transmission of a waveform-bearing microwave signal to the phase detector by setting a first coupler and a second coupler between the phase detector and the circulator, enabling the phase detector to accurately detect whether the output microwave is at the optimal frequency point based on the phase difference between the microwave signals.

[0017] In one possible design, the aerosol generating device also includes a resistive element connected to a second coupler.

[0018] In this design, a resistive element is connected to the second coupler connected to the third end of the circulator, which enables the second coupler to transmit the microwave signal reflected by the atomizing cavity to the phase detector.

[0019] In some possible implementation schemes, the resistive element is selected as a standard resistor with a resistance of 50 ohms.

[0020] In one possible design, the microwave component includes: a microwave generator; a power amplifier, with a first terminal of the power amplifier connected to the microwave generator and a second terminal of the power amplifier connected to the first terminal of the circulator.

[0021] In this design, the microwave assembly includes a microwave generator as a microwave source and a power amplifier connected to the microwave generator. The power amplifier amplifies the microwaves generated by the microwave generator. The power amplifier is located between the power generator and the first end of the circulator. After the microwave generator is powered on and generates microwaves, the microwaves are amplified by the power amplifier and then fed into the atomizing cavity through the circulator.

[0022] Secondly, embodiments of this application propose a control method for an aerosol generating device, used in the aerosol generating device of the first aspect described above, comprising: receiving a voltage signal output by a phase detector when the microwave component is in operation; and adjusting the microwave frequency of the microwave component according to the voltage signal.

[0023] The control method for the aerosol generating device provided in this application is used to control any possible design of the aerosol generating device in the first aspect described above. The aerosol generating device includes a housing, within which an atomizing chamber is disposed. The atomizing chamber contains an aerosol generating matrix, which is atomized within the atomizing chamber by microwaves. A microwave assembly is disposed within the housing, optionally located outside or inside the housing. A circulator is mounted outside the atomizing chamber. The microwave output terminal of the microwave assembly is connected to a first terminal of the circulator, and a second terminal of the circulator is connected to the atomizing chamber. Microwaves output from the microwave assembly are fed into the atomizing chamber through the first and second terminals of the circulator. The aerosol generating matrix within the atomizing chamber is heated under the action of microwaves, releasing aerosols. The second terminal of the circulator is connected to the atomizing chamber via a coaxial cable to feed microwaves into the atomizing chamber. The second end of the circulator can also receive the microwave signal fed back from the atomizing cavity and transmit the feedback microwave signal through the second end of the circulator to the third end of the circulator. The third end and the first end of the circulator are both connected to the phase detector. The phase detector can receive the microwave signals sent by the third end and the first end of the circulator, and the phase detector can calculate the phase difference between the two microwave signals and transmit the voltage signal related to the phase difference to the controller.

[0024] When the microwave component is operational, the microwaves generated by the component are fed into the atomizing cavity through the first and second ends of the circulator. The second end of the circulator transmits the microwave signal reflected from the atomizing cavity to the phase detector via the third end. The phase detector also acquires the microwave signal fed into the atomizing cavity through the first end of the circulator. By comparing the waveforms of the two microwave signals, the phase difference is calculated, and the corresponding voltage signal is transmitted to the controller. The controller controls the microwave component based on the voltage signal. The controller can determine whether the microwave output from the component is at the optimal frequency based on the voltage value of the phase detector output signal. If it is not at the optimal frequency, the controller adjusts the microwave frequency of the output microwave.

[0025] In this embodiment, the first and third ends of the circulator are connected to a phase detector. The phase detector detects whether the current frequency is at the optimal point based on the phase difference of the waveform of the acquired microwave signal, and controls the microwave component to adjust the microwave frequency of the output microwave based on the detection result. This achieves the goal of not reducing the output power of the microwave component during the microwave frequency adjustment process, thereby improving the heating and atomization efficiency of the aerosol generating device for the aerosol generating matrix.

[0026] In addition, the control method for the aerosol generating device in the above-described technical solution provided in this application may also have the following additional technical features:

[0027] In one possible design, adjusting the microwave frequency of the microwave component based on the voltage signal includes: acquiring the numerical relationship between the voltage value of the voltage signal and a preset voltage value; and controlling the microwave component to adjust the microwave frequency based on the numerical relationship.

[0028] In this design, the voltage value of the received voltage signal is determined and compared with a preset voltage value. Based on the relationship between the voltage value and the preset voltage value, it can be determined whether the current microwave frequency is at the optimal frequency point, and the microwave frequency output by the microwave component can be adjusted accordingly.

[0029] It is worth noting that the phase detector outputs a voltage value based on the phase difference between two received microwave signals. These two microwave signals include a first microwave signal received at the first end of the circulator and fed into the atomizing cavity, and a second microwave signal received at the second end of the circulator and reflected from the atomizing cavity. The closer the phase difference between the first and second microwave signals is to zero, the closer the current microwave frequency is to the optimal frequency point. Consequently, the voltage value of the phase detector's output signal is closer to the preset voltage value. Therefore, the controller can accurately determine whether the current microwave frequency needs adjustment based on the numerical relationship between the voltage signal value and the preset voltage value, thus achieving accurate adjustment of the microwave frequency output by the microwave component.

[0030] In this embodiment, the phase difference of the acquired microwave signal is calculated by a phase detector, and the voltage signal corresponding to the phase difference is output to the controller. The controller can accurately adjust the microwave frequency output by the microwave component by comparing the voltage value of the voltage signal with the preset voltage value.

[0031] In one possible design, the microwave component is controlled to adjust its microwave frequency according to a numerical relationship, including: when the voltage value is greater than or equal to a preset voltage value, the microwave component is controlled to maintain its current microwave frequency; when the voltage value is less than the preset voltage value, the microwave frequency of the microwave component is adjusted according to a preset adjustment value.

[0032] In this design, when the detected voltage signal value is greater than or equal to a preset voltage value, it is determined that the microwave frequency output by the microwave component is near the optimal frequency point. At this time, the current microwave frequency of the microwave component is maintained, ensuring continuous output of microwaves at the optimal frequency. Conversely, when the detected voltage signal value is less than the preset voltage value, it is determined that the microwave frequency output by the microwave component is far from the optimal frequency point. The microwave component is then controlled to adjust its output microwave frequency to approach the optimal frequency point, thereby improving the microwave heating atomization effect.

[0033] Specifically, when the phase detector detects a phase difference of 0 between two microwave signals, meaning the current microwave frequency is at the optimal frequency point, the voltage value of the voltage signal output by the phase detector is the target voltage value. A preset voltage value is then determined based on this target voltage value. Since the minimum phase difference is 0°, the maximum value of the voltage signal is the target voltage value.

[0034] For example, the phase detector is selected as AD8302 phase detector. When the phase difference between the first microwave signal and the second microwave signal is detected to be 0°, the voltage value of the output voltage signal is 1.8V, that is, the target voltage value is 1.8V. Then the preset voltage value is set to 1.7V.

[0035] It is worth noting that when adjusting the microwave frequency of a microwave component by frequency sweeping, the initial frequency of the sweep is selected as the current microwave frequency, and there is no need to start the sweep from the initial frequency point.

[0036] This embodiment of the application compares the voltage value of the voltage signal output by the phase detector with a preset voltage value to determine whether the current microwave frequency is at the optimal frequency point, thereby improving the accuracy of detection.

[0037] In one possible design, adjusting the microwave frequency of the microwave output by the microwave component according to a preset adjustment value includes: determining the adjustment trend of the microwave frequency; adjusting the microwave frequency according to the preset adjustment value and the adjustment trend until the voltage value of the voltage signal is greater than or equal to the preset voltage value.

[0038] In this design, during the process of adjusting the microwave frequency output by the microwave component, the current microwave frequency is used as the initial microwave frequency. The microwave component is controlled to perform frequency sweep operation according to the preset adjustment value. During the frequency sweep operation of the microwave component, the phase detector continuously transmits a voltage signal to the controller. When the controller detects that the voltage value of the voltage signal is greater than or equal to the preset voltage value, it determines that the microwave frequency is close to the optimal frequency point and controls the microwave component to stop the frequency sweep operation, so that the microwave component continuously outputs microwaves close to the optimal frequency point.

[0039] Before controlling the microwave component to start frequency sweeping, it is necessary to determine the adjustment trend of the microwave frequency output by the microwave component during the frequency sweeping process. After determining the adjustment trend, the microwave component is controlled to sweep frequency according to the adjustment trend and the preset adjustment value.

[0040] For example, when it is determined that the adjustment trend is to increase the microwave frequency, the current microwave frequency is used as the starting point, and the microwave frequency is increased multiple times according to the preset adjustment value. During the process of increasing the microwave frequency, the voltage signal sent by the phase detector is continuously read. When the voltage value of the detected voltage signal is greater than or equal to the preset voltage value, the microwave frequency adjustment is stopped.

[0041] This application embodiment determines the frequency adjustment trend before frequency sweeping, controls the microwave component to perform frequency sweeping according to the determined frequency adjustment trend and preset adjustment value, and determines whether the current microwave frequency has reached the optimal frequency range by continuously detecting the voltage value of the voltage signal. This achieves accurate finding of the microwave frequency of the microwave component output without reducing the operating power of the microwave component.

[0042] In some embodiments, the preset adjustment value ranges from 5 MHz to 10 MHz.

[0043] In one possible design, the adjustment trend includes an increasing trend and a decreasing trend. Determining the adjustment trend of the microwave frequency includes: increasing the microwave frequency of the microwave component according to a preset adjustment value; detecting the voltage value change state of the voltage signal; determining the adjustment trend as an increasing trend when the voltage value is increasing; and determining the adjustment trend as a decreasing trend when the voltage value is decreasing.

[0044] In this design, before the microwave component begins frequency sweeping, the microwave component is controlled to increase the microwave frequency by a preset adjustment value. The voltage signal's change in value is detected. If the voltage signal is increasing, the increased microwave frequency is determined to be closer to the optimal frequency, thus establishing an increasing adjustment trend. Conversely, if the voltage signal is decreasing, the increased microwave frequency is determined to be further away from the optimal frequency, thus establishing a decreasing adjustment trend.

[0045] This application embodiment controls the microwave component to increase the microwave frequency by a preset adjustment value before the frequency sweep operation begins, and determines the adjustment trend of the microwave frequency output by the microwave component based on the voltage value change trend of the voltage signal, thereby achieving the effect of quickly determining the microwave frequency adjustment trend.

[0046] In one possible design, the adjustment trend includes both an increasing trend and a decreasing trend. Determining the adjustment trend of the microwave frequency includes: decreasing the microwave frequency of the microwave component according to a preset adjustment value; detecting the voltage value change state of the voltage signal; determining the adjustment trend as a decreasing trend when the voltage value is increasing; and determining the adjustment trend as an increasing trend when the voltage value is decreasing.

[0047] In this design, before the microwave component begins frequency sweeping, the microwave component is controlled to decrease the microwave frequency by a preset adjustment value. The voltage signal's change in value is detected. If the voltage signal is increasing, it is determined that the decreased microwave frequency is closer to the optimal frequency point, thus determining the adjustment trend as decreasing. If the voltage signal is decreasing, it is determined that the decreased microwave frequency is further away from the optimal frequency point, thus determining the adjustment trend as increasing.

[0048] This application embodiment controls the microwave component to reduce the microwave frequency by a preset adjustment value before the frequency sweep operation begins, and determines the adjustment trend of the microwave frequency output by the microwave component based on the voltage value change trend of the voltage signal, thereby achieving the effect of quickly determining the microwave frequency adjustment trend.

[0049] In one possible design, before the microwave component is in operation and receives the voltage signal output by the phase detector, the design further includes controlling the microwave component to operate at a preset operating power and a preset microwave frequency.

[0050] In this design, the microwave components are controlled to start operating according to preset microwave power and preset microwave frequency before receiving the voltage signal output by the phase detector.

[0051] Thirdly, embodiments of this application propose a control device for an aerosol generating apparatus, used in the aerosol generating apparatus of the first aspect, comprising: a receiving module for receiving a voltage signal output by a phase detector when the microwave component is in operation; and an adjustment module for adjusting the microwave frequency of the microwave component according to the voltage signal.

[0052] The control device for the aerosol generating apparatus provided in this application is used to control any possible design of the aerosol generating apparatus in the first aspect described above. The aerosol generating apparatus includes a housing, within which an atomizing chamber is disposed. The atomizing chamber contains an aerosol generating matrix, which is atomized within the atomizing chamber by microwaves. A microwave assembly is disposed within the housing, optionally located outside or inside the housing. A circulator is mounted outside the atomizing chamber. The microwave output terminal of the microwave assembly is connected to a first terminal of the circulator, and a second terminal of the circulator is connected to the atomizing chamber. Microwaves output from the microwave assembly are fed into the atomizing chamber through the first and second terminals of the circulator. The aerosol generating matrix within the atomizing chamber is heated under the action of microwaves, releasing aerosols. The second terminal of the circulator is connected to the atomizing chamber via a coaxial cable to feed microwaves into the atomizing chamber. The second end of the circulator can also receive the microwave signal fed back from the atomizing cavity and transmit the feedback microwave signal through the second end of the circulator to the third end of the circulator. The third end and the first end of the circulator are both connected to the phase detector. The phase detector can receive the microwave signals sent by the third end and the first end of the circulator, and the phase detector can calculate the phase difference between the two microwave signals and transmit the voltage signal related to the phase difference to the controller.

[0053] When the microwave component is operational, the microwaves generated by the component are fed into the atomizing cavity through the first and second ends of the circulator. The second end of the circulator transmits the microwave signal reflected from the atomizing cavity to the phase detector via the third end. The phase detector also acquires the microwave signal fed into the atomizing cavity through the first end of the circulator. By comparing the waveforms of the two microwave signals, the phase difference is calculated, and the corresponding voltage signal is transmitted to the controller. The controller controls the microwave component based on the voltage signal. The controller can determine whether the microwave output from the component is at the optimal frequency based on the voltage value of the phase detector output signal. If it is not at the optimal frequency, the controller adjusts the microwave frequency of the output microwave.

[0054] In this embodiment, the first and third ends of the circulator are connected to a phase detector. The phase detector detects whether the current frequency is at the optimal point based on the phase difference of the waveform of the acquired microwave signal, and controls the microwave component to adjust the microwave frequency of the output microwave based on the detection result. This achieves the goal of not reducing the output power of the microwave component during the microwave frequency adjustment process, thereby improving the heating and atomization efficiency of the aerosol generating device for the aerosol generating matrix.

[0071] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0072] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0073] The following reference Figures 1 to 9 This application describes a control method for an aerosol generating apparatus, a control device for an aerosol generating apparatus, an aerosol generating apparatus, and a readable storage medium according to some embodiments of the present application.

[0074] Example 1:

[0075] like Figure 1 As shown, the first embodiment of this application provides an aerosol generating device 100, including: an atomizing chamber 102, a microwave component 104, a circulator 106, a phase detector 108, and a controller 110.

[0076] The first end of the circulator 106 is connected to the microwave assembly, and the second end of the circulator 106 is used to feed microwaves into the atomizing cavity 102 and to receive microwaves reflected by the atomizing cavity 102.

[0077] The signal input terminal of the phase detector 108 is connected to the first terminal and the third terminal of the circulator 106;

[0078] The controller 110 is connected to the signal output terminal of the phase detector 108. The controller 110 is used to receive the voltage signal output by the phase detector 108 when the microwave component 104 is in operation; and adjust the microwave frequency of the microwave output by the microwave component 104 according to the voltage signal.

[0079] The aerosol generating device 100 provided in this embodiment includes: an atomizing chamber 102, a microwave component 104, a circulator 106, a phase detector 108, and a controller 110. The atomizing chamber 102 is disposed within the housing of the aerosol generating device 100. The atomizing chamber 102 is used to contain the aerosol generating matrix, which can be atomized within the atomizing chamber 102 by microwave action. The microwave component 104 is disposed within the housing, and can be optionally disposed outside or inside the housing. The circulator 106 is installed outside the atomizing chamber 102. The microwave output terminal of the microwave component 104 is connected to the first terminal of the circulator 106, and the second terminal of the circulator 106 is connected to the atomizing chamber 102. The microwaves output by the microwave component 104 are fed into the atomizing chamber 102 through the first and second terminals of the circulator 106. The aerosol generating matrix within the atomizing chamber 102 is heated under the action of microwaves, releasing aerosols. The second end of the circulator 106 can also receive the microwave signal fed back from the atomizing cavity 102, and transmit the feedback microwave signal through the second end of the circulator 106 to the third end of the circulator 106. The third end and the first end of the circulator 106 are both connected to the phase detector 108. The phase detector 108 can receive the microwave signals sent by the third end and the first end of the circulator 106, and the phase detector 108 can calculate the phase difference between the two microwave signals and transmit the phase difference-related voltage signal to the controller 110. The controller 110 determines whether the microwave fed into the atomizing cavity 102 is at the optimal frequency point based on the received voltage signal. If it is determined that it is not at the optimal frequency point, the controller adjusts the microwave frequency of the microwave output by the microwave component 104 to the optimal frequency point.

[0080] Specifically, the phase detector 108 continuously receives microwave signals transmitted from the first and third terminals of the circulator 106. A first microwave signal is transmitted to the phase detector 108 via the first terminal of the circulator 106, and a second microwave signal is transmitted to the phase detector 108 via the second terminal of the circulator 106. The phase detector 108 automatically detects the phase difference between the first and second microwave signals and outputs a voltage signal to the controller 110 according to the detected phase difference. The controller 110 determines whether the microwave component 104 is currently operating at the optimal frequency by comparing the voltage value of the voltage signal with a preset voltage value. If it is not operating at the optimal frequency, the controller adjusts the microwave frequency of the output microwave.

[0081] Among them, the circulator 106 is a device for unidirectional circular transmission of electromagnetic waves. The conduction direction of the signal in the circulator 106 is from the first end to the second end, from the second end to the third end, and from the third end to the first end.

[0082] like Figure 2As shown, exemplarily, the phase detector 108 is selected as an AD8302 phase detector. When the phase difference between the first microwave signal and the second microwave signal is detected to be 0°, the output voltage signal has a value of 1.8V. The larger the phase difference between the first microwave signal and the second microwave signal, the smaller the output voltage signal value. The phase detector 108 can continuously detect the phase difference between the two microwave signals and continuously send the corresponding voltage signal to the controller 110.

[0083] In related technologies, during the microwave heating of the aerosol generating matrix by controlling the operation of the microwave components in an aerosol generating device, the resonant frequency within the atomization cavity continuously changes as the aerosol generating matrix gradually atomizes. Therefore, after the aerosol generating device has been running for a period of time, it is necessary to re-scan the frequency of the aerosol generating device to find a new optimal frequency point. Since existing technologies determine whether the current microwave frequency is at the optimal frequency point based on the standing wave ratio (VSWR), the operating power of the microwave components needs to be reduced during the frequency scanning process.

[0084] In this embodiment, the first and third ends of the circulator 106 are connected to the phase detector 108. The phase detector 108 detects whether the current frequency point is at the optimal point based on the phase difference of the waveform of the collected microwave signal, and controls the microwave component 104 to adjust the microwave frequency of the output microwave based on the detection result. This achieves the goal of not reducing the output power of the microwave component 104 during the microwave frequency adjustment process, thereby improving the heating and atomization efficiency of the aerosol generating device 100 on the aerosol generating matrix.

[0085] like Figure 1 As shown, in any of the above embodiments, the aerosol generating device 100 further includes: a first coupler 112 connected between the first end of the circulator 106 and the signal input end of the phase detector 108; and a second coupler 114 connected between the third end of the circulator 106 and the signal input end of the phase detector 108.

[0086] In this embodiment, the aerosol generating device 100 further includes a first coupler 112 and a second coupler 114. The first coupler 112 and the second coupler 114 are respectively disposed at the first end and the third end of the circulator 106, and both the first coupler 112 and the second coupler 114 are connected to the phase detector 108.

[0087] The first coupler 112 transmits the first microwave signal fed into the atomizing cavity 102 by the microwave component 104 to the phase detector 108, and the second coupler 114 transmits the second microwave signal reflected from the atomizing cavity 102 to the phase detector 108. The phase detector 108 determines the phase difference between the first and second microwave signals by comparing their waveforms, and then transmits the corresponding voltage signal to the controller 110.

[0088] In this embodiment of the application, by setting a first coupler 112 and a second coupler 114 between the phase detector 108 and the circulator 106, a microwave signal with a waveform is transmitted to the phase detector 108, so that the phase detector 108 can accurately detect whether the output microwave is at the optimal frequency point based on the phase difference between the microwave signals.

[0089] In any of the above embodiments, the aerosol generating device 100 further includes a resistive element 116 connected to the second coupler 114.

[0090] In this embodiment, a resistive element 116 is connected to the second coupler 114 connected to the third end of the circulator 106, which enables the second coupler 114 to transmit the microwave signal reflected by the atomizing cavity 102 to the phase detector 108.

[0091] In some possible implementation schemes, resistive element 116 is selected as a standard resistor with a resistance of 50 ohms.

[0092] In any of the above embodiments, the microwave component 104 includes: a microwave generator; a power amplifier, a first end of which is connected to the microwave generator, and a second end of which is connected to the first end of the circulator 106.

[0093] In this embodiment, the microwave assembly 104 includes a microwave generator as a microwave source and a power amplifier connected to the microwave generator. The power amplifier amplifies the microwaves generated by the microwave generator. The power amplifier is located between the power generator and the first end of the circulator 106. After the microwave generator is powered on and generates microwaves, the microwaves are amplified by the power amplifier and then conducted through the circulator 106 before being fed into the atomizing cavity 102.

[0094] Example 2:

[0095] like Figure 3 As shown, a second embodiment of this application provides a control method for an aerosol generating device, used to control the aerosol generating device of the above embodiment. The control method includes:

[0096] Step 302: While the microwave component is in operation, receive the voltage signal output by the phase detector;

[0097] Step 304: Adjust the microwave frequency of the microwave component according to the voltage signal.

[0098] The control method for the aerosol generating device provided in this embodiment is used to control any possible design of the aerosol generating device in the first aspect described above. The aerosol generating device includes a housing, within which an atomizing chamber is provided. The atomizing chamber contains an aerosol generating matrix, which is atomized within the atomizing chamber by microwaves. A microwave assembly is disposed within the housing, optionally located outside or inside the housing. A circulator is mounted outside the atomizing chamber. The microwave output terminal of the microwave assembly is connected to a first terminal of the circulator, and a second terminal of the circulator is connected to the atomizing chamber. Microwaves output from the microwave assembly are fed into the atomizing chamber through the first and second terminals of the circulator. The aerosol generating matrix within the atomizing chamber is heated under the action of microwaves, releasing aerosols. The second terminal of the circulator is connected to the atomizing chamber via a coaxial cable to feed microwaves into the atomizing chamber. The second end of the circulator can also receive the microwave signal fed back from the atomizing cavity and transmit the feedback microwave signal through the second end of the circulator to the third end of the circulator. The third end and the first end of the circulator are both connected to the phase detector. The phase detector can receive the microwave signals sent by the third end and the first end of the circulator, and the phase detector can calculate the phase difference between the two microwave signals and transmit the voltage signal related to the phase difference to the controller.

[0099] When the microwave component is operational, the microwaves generated by the component are fed into the atomizing cavity through the first and second ends of the circulator. The second end of the circulator transmits the microwave signal reflected from the atomizing cavity to the phase detector via the third end. The phase detector also acquires the microwave signal fed into the atomizing cavity through the first end of the circulator. By comparing the waveforms of the two microwave signals, the phase difference is calculated, and the corresponding voltage signal is transmitted to the controller. The controller controls the microwave component based on the voltage signal. The controller can determine whether the microwave output from the component is at the optimal frequency based on the voltage value of the phase detector output signal. If it is not at the optimal frequency, the controller adjusts the microwave frequency of the output microwave.

[0100] In this embodiment, the first and third ends of the circulator are connected to a phase detector. The phase detector detects whether the current frequency is at the optimal point based on the phase difference of the waveform of the acquired microwave signal, and controls the microwave component to adjust the microwave frequency of the output microwave based on the detection result. This achieves the goal of not reducing the output power of the microwave component during the microwave frequency adjustment process, thereby improving the heating and atomization efficiency of the aerosol generating device for the aerosol generating matrix.

[0101] like Figure 4 As shown, in the above embodiment, adjusting the microwave frequency of the microwave component according to the voltage signal includes:

[0102] Step 402: Obtain the numerical relationship between the voltage value of the voltage signal and the preset voltage value;

[0103] Step 404: Based on the numerical relationship, control the microwave component to adjust the microwave frequency.

[0104] In this embodiment, the voltage value of the received voltage signal is determined, and the voltage value is compared with a preset voltage value. Based on the relationship between the voltage value and the preset voltage value, it can be determined whether the current microwave frequency is at the optimal frequency point, and the microwave frequency of the microwave output by the microwave component can be adjusted accordingly.

[0105] It is worth noting that the phase detector outputs a voltage value based on the phase difference between two received microwave signals. These two microwave signals include a first microwave signal received at the first end of the circulator and fed into the atomizing cavity, and a second microwave signal received at the second end of the circulator and reflected from the atomizing cavity. The closer the phase difference between the first and second microwave signals is to zero, the closer the current microwave frequency is to the optimal frequency point. Consequently, the voltage value of the phase detector's output signal is closer to the preset voltage value. Therefore, the controller can accurately determine whether the current microwave frequency needs adjustment based on the numerical relationship between the voltage signal value and the preset voltage value, thus achieving accurate adjustment of the microwave frequency output by the microwave component.

[0106] In this embodiment, the phase difference of the acquired microwave signal is calculated by a phase detector, and the voltage signal corresponding to the phase difference is output to the controller. The controller can accurately adjust the microwave frequency output by the microwave component by comparing the voltage value of the voltage signal with the preset voltage value.

[0107] In any of the above embodiments, controlling the microwave component to adjust the microwave frequency according to the numerical relationship includes:

[0108] When the voltage value is greater than or equal to the preset voltage value, the microwave component is controlled to maintain the current microwave frequency;

[0109] When the voltage value is lower than the preset voltage value, the microwave frequency of the microwave component is adjusted according to the preset adjustment value.

[0110] In this embodiment, when the detected voltage value of the voltage signal is greater than or equal to a preset voltage value, it is determined that the microwave frequency output by the microwave component is near the optimal frequency point. At this time, the current microwave frequency of the microwave component is maintained, allowing the microwave component to continuously output microwaves at the optimal frequency point. When the detected voltage value of the voltage signal is less than the preset voltage value, it is determined that the microwave frequency output by the microwave component is far from the optimal frequency point. The microwave component is then controlled to adjust its output microwave frequency to approach the optimal frequency point, thereby improving the microwave heating atomization effect.

[0111] Specifically, when the phase detector detects a phase difference of 0 between two microwave signals, meaning the current microwave frequency is at the optimal frequency point, the voltage value of the voltage signal output by the phase detector is the target voltage value. A preset voltage value is then determined based on this target voltage value. Since the minimum phase difference is 0°, the maximum value of the voltage signal is the target voltage value.

[0112] For example, the phase detector is selected as AD8302 phase detector. When the phase difference between the first microwave signal and the second microwave signal is detected to be 0°, the voltage value of the output voltage signal is 1.8V, that is, the target voltage value is 1.8V. Then the preset voltage value is set to 1.7V.

[0113] It is worth noting that when adjusting the microwave frequency of a microwave component by frequency sweeping, the initial frequency of the sweep is selected as the current microwave frequency, and there is no need to start the sweep from the initial frequency point.

[0114] This embodiment of the application compares the voltage value of the voltage signal output by the phase detector with a preset voltage value to determine whether the current microwave frequency is at the optimal frequency point, thereby improving the accuracy of detection.

[0115] like Figure 5 As shown, in any of the above embodiments, adjusting the microwave frequency of the microwave output by the microwave component according to a preset adjustment value includes:

[0116] Step 502: Determine the adjustment trend of the microwave frequency;

[0117] Step 504: Adjust the microwave frequency according to the preset adjustment value and adjustment trend until the voltage value of the voltage signal is greater than or equal to the preset voltage value.

[0118] In this embodiment, during the process of adjusting the microwave frequency of the microwave component outputting microwaves, the current microwave frequency is used as the initial microwave frequency, and the microwave component is controlled to perform frequency sweep operation according to the preset adjustment value. During the frequency sweep operation of the microwave component, the phase detector continuously transmits a voltage signal to the controller. When the controller detects that the voltage value of the voltage signal is greater than or equal to the preset voltage value, it determines that the microwave frequency is close to the optimal frequency point, controls the microwave component to stop the frequency sweep operation, and makes the microwave component continuously output microwaves close to the optimal frequency point.

[0119] Before controlling the microwave component to start frequency sweeping, it is necessary to determine the adjustment trend of the microwave frequency output by the microwave component during the frequency sweeping process. After determining the adjustment trend, the microwave component is controlled to sweep frequency according to the adjustment trend and the preset adjustment value.

[0120] For example, when it is determined that the adjustment trend is to increase the microwave frequency, the current microwave frequency is used as the starting point, and the microwave frequency is increased multiple times according to the preset adjustment value. During the process of increasing the microwave frequency, the voltage signal sent by the phase detector is continuously read. When the voltage value of the detected voltage signal is greater than or equal to the preset voltage value, the microwave frequency adjustment is stopped.

[0121] This application embodiment determines the frequency adjustment trend before frequency sweeping, controls the microwave component to perform frequency sweeping according to the determined frequency adjustment trend and preset adjustment value, and determines whether the current microwave frequency has reached the optimal frequency range by continuously detecting the voltage value of the voltage signal. This achieves accurate finding of the microwave frequency of the microwave component output without reducing the operating power of the microwave component.

[0122] In some embodiments, the preset adjustment value ranges from 5 MHz to 10 MHz.

[0123] like Figure 6 As shown, in any of the above embodiments, the adjustment trend includes an increasing trend and a decreasing trend. Determining the adjustment trend of the microwave frequency includes:

[0124] Step 602: Increase the microwave frequency of the microwave component according to the preset adjustment value;

[0125] Step 604: Detect the change in the voltage value of the voltage signal;

[0126] Step 606: Determine the adjustment trend based on the change in voltage value.

[0127] Specifically, when the voltage value is increasing, the adjustment trend is determined to be increasing; when the voltage value is decreasing, the adjustment trend is determined to be decreasing.

[0128] In this embodiment, before the microwave component begins frequency sweeping, the microwave component is controlled to increase the microwave frequency by a preset adjustment value. The voltage value of the voltage signal is detected to change. If the voltage value of the voltage signal is detected to be increasing, it is determined that the increased microwave frequency is closer to the optimal frequency point, thus determining the adjustment trend as an increasing trend. If the voltage value of the voltage signal is detected to be decreasing, it is determined that the increased microwave frequency is further away from the optimal frequency point, thus determining the adjustment trend as a decreasing trend.

[0129] This application embodiment controls the microwave component to increase the microwave frequency by a preset adjustment value before the frequency sweep operation begins, and determines the adjustment trend of the microwave frequency output by the microwave component based on the voltage value change trend of the voltage signal, thereby achieving the effect of quickly determining the microwave frequency adjustment trend.

[0130] like Figure 7As shown, in any of the above embodiments, the adjustment trend includes an increasing trend and a decreasing trend. Determining the adjustment trend of the microwave frequency includes:

[0131] Step 702: Reduce the microwave frequency of the microwave component according to the preset adjustment value;

[0132] Step 704: Detect the change in the voltage value of the voltage signal;

[0133] Step 706: Determine the adjustment trend based on the change in voltage value.

[0134] Specifically, when the voltage value is increasing, the adjustment trend is determined to be decreasing; when the voltage value is decreasing, the adjustment trend is determined to be increasing.

[0135] In this embodiment, before the microwave component begins frequency sweeping, the microwave component is controlled to decrease the microwave frequency by a preset adjustment value. The voltage value of the voltage signal is detected to change. If the voltage value of the voltage signal is detected to be increasing, it is determined that the decreased microwave frequency is closer to the optimal frequency point, thus determining the adjustment trend as a decreasing trend. If the voltage value of the voltage signal is detected to be decreasing, it is determined that the decreased microwave frequency is further away from the optimal frequency point, thus determining the adjustment trend as an increasing trend.

[0136] This application embodiment controls the microwave component to reduce the microwave frequency by a preset adjustment value before the frequency sweep operation begins, and determines the adjustment trend of the microwave frequency output by the microwave component based on the voltage value change trend of the voltage signal, thereby achieving the effect of quickly determining the microwave frequency adjustment trend.

[0137] In any of the above embodiments, before receiving the voltage signal output by the phase detector while the microwave component is in operation, the method further includes: controlling the microwave component to operate at a preset operating power and a preset microwave frequency.

[0138] In this embodiment, before receiving the voltage signal output by the phase detector, the microwave component is controlled to start operating according to a preset microwave power and a preset microwave frequency.

[0142] Adjustment module 804 is used to adjust the microwave frequency of the microwave component according to the voltage signal.

[0143] The control device for the aerosol generating apparatus provided in this embodiment is used to control any possible design of the aerosol generating apparatus in the first aspect described above. The aerosol generating apparatus includes a housing, within which an atomizing chamber is provided.

The second end of the circulator transmits the microwave signal reflected from the atomizing cavity to the phase detector via the third end.
