Description

Technical Field

[0001] This invention belongs to the field of electronic cigarette technology, and more specifically, relates to an aerosol generating device and its control method, control device and readable storage medium. Background Technology

[0002] A heat-not-burning (HNB) device is a combination of a heating element and an aerosol-generating substrate (treated plant leaf products). The external heating element heats the aerosol-generating substrate to a temperature sufficient to produce aerosols but not hot enough to burn them, allowing the substrate to generate the desired aerosols 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 These appliances require long preheating times, cannot be freely stopped or withdrawn, and suffer from uneven carbonization of the aerosol-generating matrix, resulting in insufficient baking and low utilization.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 stopping of the cigarette; b) There is no heating element, so there are no issues with chip breakage 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, aerosol generating devices determine the optimal frequency of microwave components by detecting the standing wave ratio using a circulator. However, due to the large size of the circulator, it is impossible to meet the requirements for miniaturization design of aerosol generating devices. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, a first aspect of the present invention provides an aerosol generating apparatus.

[0007] A second aspect of the present invention provides a method for controlling an aerosol generating device.

[0008] A third aspect of the present invention provides a control device for an aerosol generating apparatus.

[0009] A fourth aspect of the present invention provides a control device for an aerosol generating apparatus.

[0010] A fifth aspect of the present invention provides a readable storage medium.

[0011] A sixth aspect of the present invention provides an aerosol generating apparatus.

[0012] In view of this, according to a first aspect of the present invention, an aerosol generating device is provided, comprising: a housing, the housing including an atomizing cavity; a microwave component connected to the housing for feeding microwaves into the atomizing cavity; a voltage acquisition component disposed in the atomizing cavity for acquiring a feedback voltage value of the atomizing cavity; and a controller connected to the voltage acquisition component for determining a target operating frequency of the microwave component based on the feedback voltage value.

[0013] The aerosol generating device provided by this invention includes a housing, a microwave component, a voltage acquisition component, and a controller. An atomization chamber is disposed within the housing, capable of containing an aerosol generating matrix. The microwave component is mounted on the housing and can feed microwaves into the atomization chamber. The aerosol generating matrix contained within the atomization chamber is heated and atomized under the action of the microwaves fed by the microwave component. Due to the resonant characteristics of the atomization chamber, the microwaves generated by the microwave component induce a current in the cavity wall structure. The voltage acquisition component can acquire the feedback voltage value of the current on the cavity wall structure and transmit the feedback voltage value to the controller. The controller can determine the energy level at the cavity wall based on the magnitude of the feedback voltage value.

[0014] Specifically, during the microwave component's frequency sweep operation, the voltage acquisition component continuously collects feedback voltage values ​​from the atomization cavity wall. The controller records multiple collected feedback voltage values. After the microwave component's frequency sweep operation is complete, the controller compares the magnitudes of the multiple feedback voltage values ​​and uses the operating frequency corresponding to the largest feedback voltage value as the target operating frequency. It can be understood that a larger feedback voltage value indicates that the microwave at the current frequency is feeding more energy into the atomization cavity. Therefore, the operating frequency corresponding to the largest feedback voltage value is the resonant frequency of the atomization cavity. Thus, controlling the microwave component to operate at the operating frequency corresponding to the largest feedback voltage value ensures that the microwave component operates at the optimal frequency point, improving the heating and atomization efficiency of the aerosol generation device on the aerosol generation matrix.

[0015] For example, the microwave generator is controlled to sweep frequency within a set frequency range, with a minimum frequency of 2.2 GHz and a maximum frequency of 2.57 GHz. During the sweep, the microwave generator starts from the minimum frequency and increases by 10 MHz every 2 milliseconds until the maximum frequency is reached. A feedback voltage value is recorded each time the operating frequency is switched. After the sweep is complete, the operating frequency corresponding to the maximum value of the feedback voltage is taken as the target operating frequency, and the microwave generator is controlled to feed microwaves into the atomization cavity according to the target operating frequency.

[0016] In related technologies, a circulator for detecting the standing wave ratio is installed in the aerosol generating device. However, the circulator occupies a large space in the aerosol generating device, and it generates heat during operation, which reduces the efficiency of the entire system.

[0017] This invention incorporates a voltage acquisition component within the atomization chamber, capable of collecting feedback voltage values ​​from the chamber walls. This allows the controller to determine the current energy input within the atomization chamber based on the feedback voltage, thereby identifying the chamber's resonant frequency—the optimal operating frequency of the microwave component. Controlling the atomization component according to this optimal frequency improves the heating and atomization efficiency of the aerosol generation device on the aerosol-generating matrix. While ensuring the accuracy and efficiency of detecting the optimal frequency of the microwave component, it eliminates the need for a bulky circulator within the atomization chamber, facilitating product miniaturization, reducing production costs, and ensuring the efficient operation of the aerosol generation device by miniaturizing the voltage acquisition component during operation.

[0018] In addition, the aerosol generating device according to the above-described technical solution provided by the present invention may also have the following additional technical features:

[0019] In one possible design, the voltage acquisition component includes: a power supply point disposed on the inner wall of the housing; and a filter component, with a first end connected to the power supply point and a second end connected to the controller.

[0020] In this design, the voltage acquisition component includes a power supply point and a filtering component. A power supply point is set on the inner wall of the housing, specifically within the atomization chamber. The voltage signal at the inner wall of the atomization chamber is acquired through this power supply point. The voltage signal is then filtered by the filtering component and transmitted to the controller, enabling the controller to acquire the feedback voltage value at the atomization chamber through the power supply point.

[0021] When microwaves are fed into the atomizing cavity, a current is generated in the cavity wall structure due to the resonant characteristics of the atomizing cavity. This invention sets a feed point inside the atomizing cavity, realizing the acquisition of the feedback voltage value at the cavity wall.

[0022] In one possible design, the filter component includes: a diode, with its first end connected to a feed point and its second end grounded; a filter circuit, with its first end connected to the first end of the diode, the second end of the filter component connected to the second end of the diode, and the filter circuit connected to a controller; wherein the second end of the diode is conducting to its first end.

[0023] In this design, the filtering component includes diodes and a filtering circuit. The diodes are rectifier diodes, and the current at the inner wall of the atomizing cavity is rectified into a DC signal. The DC signal is then filtered by the filtering circuit, and the filtered DC signal is sent to the controller. The controller can determine the feedback voltage value at the cavity wall of the atomizing cavity by receiving the filtered DC signal.

[0024] Specifically, the diode is connected in parallel with the filter circuit. The first terminal of the diode is the negative terminal, which is connected to the feed point. The positive terminal of the diode is connected to the ground terminal. The controller is connected to the rectifier circuit. The feedback voltage value of the negative current on the cavity wall of the atomizing chamber can be collected through the negative terminal of the diode.

[0025] This invention enables the filter component to collect the feedback voltage value of the negative current on the cavity wall of the atomizing cavity through the feed point by setting the diode and the filter circuit in parallel and connecting the negative terminal of the diode to the feed point.

[0026] In one possible design, the filter component includes: a diode, with its first end connected to a feed point; a filter circuit, with its first end connected to the second end of the diode, the second end of the filter circuit grounded, and the filter circuit connected to a controller; wherein the first end of the diode is conducting to the second end.

[0027] In this design, the filtering component includes diodes and a filtering circuit. The diodes are rectifier diodes, and the current at the inner wall of the atomizing cavity is rectified into a DC signal. The DC signal is then filtered by the filtering circuit, and the filtered DC signal is sent to the controller. The controller can determine the feedback voltage value at the cavity wall of the atomizing cavity by receiving the filtered DC signal.

[0028] Specifically, the diode is connected in series with the filter circuit. The first segment of the diode is the positive terminal, which is connected to the feed point. The negative terminal of the diode is connected to the controller through the rectifier circuit. The feedback voltage value of the forward current on the cavity wall of the atomizing chamber can be collected through the positive terminal of the diode.

[0029] This invention achieves the feedback voltage value of the positive current on the cavity wall of the atomizing cavity by setting the diode and the filter circuit in series and connecting the positive terminal of the diode to the feed point.

[0030] In one possible design, the filter circuit includes any one or a combination of the following: a capacitor filter circuit, a resistor-capacitor filter circuit, and an inductor-capacitor filter circuit.

[0031] In this design, the filter circuit is selected as a DC filter circuit, specifically, it can be one or a combination of capacitor filter circuit, resistor-capacitor filter circuit (RC), and inductor-capacitor filter circuit (LC).

[0032] In some embodiments, the filter circuit is selected as an inductor-capacitor filter circuit, and the diode is connected in series with the inductor-capacitor filter circuit.

[0033] In these embodiments, the first terminal of the diode is connected to the feed point, and the second terminal of the diode is connected to an inductor and a capacitor connected in series. The capacitor is connected to the controller, and the common terminal of the capacitor and the controller is grounded. The diode conducts from the first terminal to the second terminal. The current at the cavity wall of the atomizing cavity is rectified by the diode into a DC current signal. The DC current signal is filtered by an inductor-capacitor filter circuit and then transmitted to the controller. The controller processes the DC current signal to obtain a feedback voltage value.

[0034] In one possible design, the power supply point includes: a through hole, disposed on the bottom wall of the atomizing cavity, with the filter component connected to the hole wall; or a conductive ring, disposed on the inner wall of the atomizing cavity, with the conductive ring close to the bottom wall of the atomizing cavity, and the filter component connected to the conductive ring; or a lead wire, with the first end of the lead wire connected to the bottom wall of the atomizing cavity and the second end of the lead wire connected to the filter component.

[0035] In this design, the power supply point can be configured in various forms, including but not limited to through holes, conductive rings, and leads.

[0036] In some embodiments, the power supply point is set as a through hole, which is opened at the bottom wall of the atomizing cavity. The sampling end of the filter component is connected to the hole wall of the through hole to collect the feedback voltage value at the hole wall position at the bottom wall of the atomizing cavity.

[0037] In some other embodiments, the feed point is set as a conductive ring, which may specifically be a copper ring. The conductive ring is placed on the inner wall of the atomizing cavity and is positioned near the bottom wall of the atomizing cavity. The sampling end of the filter component is connected to the conductive ring, which is located on the cavity wall of the atomizing cavity. The conductive ring can guide the current at the cavity wall to the filter component, thereby acquiring the feedback voltage value at the cavity wall of the atomizing cavity through the conductive ring.

[0038] According to a second aspect of the present invention, a control method for an aerosol generating device is provided. The aerosol generating device includes a microwave component, an atomizing cavity, and a voltage acquisition component. The control method for the aerosol generating device includes: controlling the microwave component to perform frequency sweep operation within a set frequency range; acquiring multiple feedback voltage values ​​of the atomizing cavity through the voltage acquisition component while the microwave component is in frequency sweep operation; determining a target frequency within the set frequency range based on the multiple feedback voltage values; and controlling the microwave component to operate at the target frequency.

[0039] The control method for an aerosol generating device provided by this invention controls the aerosol generating device, which includes a housing, a microwave component, a voltage acquisition component, and a controller. An atomization chamber is provided inside the housing, capable of containing an aerosol generating matrix. The microwave component is mounted on the housing and can feed microwaves into the atomization chamber. The aerosol generating matrix contained in the atomization chamber is heated and atomized under the action of the microwaves fed by the microwave component. Due to the resonant characteristics of the atomization chamber, the microwaves generated by the microwave component induce a current in the cavity wall structure of the atomization chamber.

[0040] With the aerosol generating matrix located within the atomization chamber, the microwave component is controlled to begin frequency sweeping within a set frequency range. During this sweeping operation, multiple feedback voltage values ​​at the chamber wall are continuously acquired by a voltage acquisition component. These feedback voltage values ​​correspond to multiple operating frequencies during the microwave component's frequency sweep. By analyzing these feedback voltage values, the target frequency within the set frequency range can be obtained. The microwave component is then controlled to feed microwaves into the atomization chamber at the target frequency to heat and atomize the aerosol generating matrix within the chamber.

[0041] Understandably, by acquiring feedback voltage values ​​during frequency sweeping and determining the target frequency based on these values, the target frequency is the operating frequency closest to the cavity's resonant frequency within the radio frequency range—that is, the optimal frequency point for the microwave component during operation. By controlling the aerosol generating device to feed microwaves into the atomization cavity at the target frequency, the atomization efficiency of the aerosol generating matrix within the atomization cavity can be improved.

[0042] In related technologies, a circulator for detecting the standing wave ratio is installed in the aerosol generating device. However, the circulator occupies a large space in the aerosol generating device, and it generates heat during operation, which reduces the efficiency of the entire system.

[0043] This invention incorporates a voltage acquisition component within the atomization chamber, capable of collecting feedback voltage values ​​from the chamber walls. This allows the controller to determine the current energy input within the atomization chamber based on the feedback voltage, thereby identifying the chamber's resonant frequency—the optimal operating frequency of the microwave component. Controlling the atomization component according to this optimal frequency improves the heating and atomization efficiency of the aerosol generation device on the aerosol-generating matrix. While ensuring the accuracy and efficiency of detecting the optimal frequency of the microwave component, it eliminates the need for a bulky circulator within the atomization chamber, facilitating product miniaturization, reducing production costs, and ensuring the efficient operation of the aerosol generation device by miniaturizing the voltage acquisition component during operation.

[0044] In addition, the control method for the aerosol generating device in the above-described technical solution provided by the present invention may also have the following additional technical features:

[0045] In one possible design, determining the target frequency within a set frequency range based on the feedback voltage value further includes: obtaining the maximum voltage value among multiple feedback voltage values; and determining the target frequency corresponding to the maximum voltage value within the set frequency range based on the maximum voltage value.

[0046] In this design, during the microwave component's frequency sweep operation, the voltage acquisition component continuously acquires feedback voltage values ​​from the atomization cavity wall. The controller records multiple acquired feedback voltage values. After the microwave component's frequency sweep operation is complete, the controller compares the magnitudes of the multiple feedback voltage values ​​and uses the operating frequency corresponding to the maximum voltage value as the target operating frequency.

[0047] It is understandable that a large feedback voltage value means that the microwave at the current frequency feeds more energy into the atomization cavity. Therefore, the operating frequency corresponding to the largest voltage value among multiple feedback voltage values ​​is the target frequency in the radio frequency range. Thus, controlling the microwave component to operate at the operating frequency corresponding to the largest feedback voltage value can ensure that the microwave component operates at the optimal frequency point, thereby improving the heating and atomization efficiency of the aerosol generation device on the aerosol generation matrix.

[0048] In one possible design, controlling the microwave component to operate within a set frequency range includes: controlling the microwave component to start operating at a first frequency within the set frequency range; and adjusting the operating frequency of the microwave component according to a set adjustment value at intervals of a first set time duration until the operating frequency reaches a second frequency within the set frequency range.

[0049] In this design, the microwave component is controlled to operate by sweeping frequencies within a set frequency range. Specifically, the microwave component starts operating at a lower first frequency within the set frequency range, and after a first set time interval, the microwave component is controlled to adjust its operating frequency to a set adjustment value until it reaches a second frequency within the set frequency range.

[0050] It is understandable that the first frequency is greater than the second frequency, or the first frequency is less than the second frequency. That is, during frequency sweep operation, the microwave component can operate by increasing the frequency from low to high within the set frequency range, or by decreasing the frequency from high to low within the set frequency range.

[0051] For example, the microwave generator is controlled to sweep frequency within a set frequency range, with a minimum frequency of 2.2 GHz and a maximum frequency of 2.57 GHz. During the sweep, the microwave generator starts from the minimum frequency and increases by 10 MHz every 2 milliseconds until the maximum frequency is reached. A feedback voltage value is recorded each time the operating frequency is switched. After the sweep is complete, the operating frequency corresponding to the maximum value of the feedback voltage is taken as the target operating frequency, and the microwave generator is controlled to feed microwaves into the atomization cavity according to the target operating frequency.

[0052] This invention adjusts the set adjustment value every first set time period by controlling the operating frequency of the microwave component, so that the microwave component has enough time to feed microwaves into the atomization cavity at each operating frequency. This improves the correspondence between multiple feedback voltage values ​​and multiple operating frequencies within the set frequency range, thereby improving the accuracy of obtaining the target frequency.

[0053] In one possible design, while the microwave component is in frequency sweep operation, multiple feedback voltage values ​​of the atomizing cavity are acquired by a voltage acquisition component, including: when the microwave component is in operation, acquiring the feedback voltage value of the atomizing cavity every first set time interval.

[0054] In this design, during the frequency sweep operation, the feedback voltage value of the atomizing cavity is collected once at a first set time interval. By corresponding the time of collecting the feedback voltage value with the time of adjusting the operating frequency during the frequency sweep operation of the microwave component, the multiple collected feedback voltage values ​​can be matched one-to-one with the operating frequencies in the set frequency range, which makes it easier to find the accurate target frequency based on the maximum voltage value among the multiple feedback voltage values.

[0055] In some embodiments, the voltage acquisition component continuously detects the feedback voltage value of the atomizing chamber and records the current feedback voltage value every first set time interval.

[0056] In other implementations, the voltage acquisition component detects and records the current feedback voltage value at first set intervals.

[0057] In one possible design, after controlling the microwave component to operate at the target frequency, the process further includes: if the microwave component operates at the target frequency for a second set time, returning to the step of controlling the microwave component to sweep the frequency within the set frequency range until a stop operation command is received.

[0058] In this design, after determining the target frequency, the microwave component is controlled to operate at the target frequency for a second set duration, and then the process returns to the step of controlling the microwave component to sweep the frequency to find the target frequency. Since the aerosol generating matrix in the aerosol generating device is heated and atomized as the microwave component operates, the aerosol generating matrix in the atomization cavity changes, causing a change in the resonant frequency of the atomization cavity. Therefore, this invention, by controlling the microwave component to operate at the target frequency for a second set duration and then returning to find the target frequency, achieves continuous updating of the target frequency of the microwave component, ensuring that the microwave component in the aerosol generating device can operate at the optimal frequency point for a long time, thus improving the atomization effect of the aerosol generating device on the aerosol generating matrix.

[0059] A third aspect of the present invention provides a control device for an aerosol generating apparatus, the aerosol generating apparatus including a microwave component, an atomizing cavity, and a voltage acquisition component. The control device for the aerosol generating apparatus includes: a control module for controlling the microwave component to perform frequency sweeping operation within a set frequency range; an acquisition module for acquiring multiple feedback voltage values ​​of the atomizing cavity through the voltage acquisition component when the microwave component is in frequency sweeping operation; a determination module for determining a target frequency within the set frequency range based on the multiple feedback voltage values; and the determination module is also used to control the microwave component to operate at the target frequency.

[0060] The control device for the aerosol generating apparatus provided by this invention controls the aerosol generating apparatus. The aerosol generating apparatus includes a housing, a microwave component, a voltage acquisition component, and a controller. An atomization chamber is provided inside the housing, capable of containing the aerosol generating matrix. The microwave component is mounted on the housing and can feed microwaves into the atomization chamber. The aerosol generating matrix contained in the atomization chamber is heated and atomized under the action of the microwaves fed by the microwave component. Due to the resonant characteristics of the atomization chamber, the microwaves generated by the microwave component induce a current in the cavity wall structure of the atomization chamber.

[0061] With the aerosol generating matrix located within the atomization chamber, the microwave component is controlled to begin frequency sweeping within a set frequency range. During this sweeping operation, multiple feedback voltage values ​​at the chamber wall are continuously acquired by a voltage acquisition component. These feedback voltage values ​​correspond to multiple operating frequencies during the microwave component's frequency sweep. By analyzing these feedback voltage values, the target frequency within the set frequency range can be obtained. The microwave component is then controlled to feed microwaves into the atomization chamber at the target frequency to heat and atomize the aerosol generating matrix within the chamber.

[0062] Understandably, by acquiring feedback voltage values ​​during frequency sweeping and determining the target frequency based on these values, the target frequency is the operating frequency closest to the cavity's resonant frequency within the radio frequency range—that is, the optimal frequency point for the microwave component during operation. By controlling the aerosol generating device to feed microwaves into the atomization cavity at the target frequency, the atomization efficiency of the aerosol generating matrix within the atomization cavity can be improved.

[0063] In related technologies, a circulator for detecting the standing wave ratio is installed in the aerosol generating device. However, the circulator occupies a large space in the aerosol generating device, and it generates heat during operation, which reduces the efficiency of the entire system.

[0064] This invention incorporates a voltage acquisition component within the atomization chamber, capable of collecting feedback voltage values ​​from the chamber walls.

[0081] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention 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 of the present invention and the features thereof can be combined with each other.

[0082] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0083] The following reference Figures 1 to 9 This invention describes an aerosol generating apparatus, a control method for the aerosol generating apparatus, a control device for the aerosol generating apparatus, and a readable storage medium according to some embodiments of the present invention.

[0084] Example 1:

[0085] like Figure 1 As shown, the first embodiment of the present invention provides an aerosol generating device 100, including: a housing 120, an atomizing chamber 122, a microwave component 140, a voltage acquisition component 160, and a controller 180.

[0086] An atomizing chamber 122 is provided inside the housing 120;

[0087] The microwave component 140 is connected to the housing 120 and is used to feed microwaves into the atomizing cavity 122;

[0088] The voltage acquisition component 160 is disposed in the atomizing chamber 122 and is used to acquire the feedback voltage value of the atomizing chamber 122;

[0089] The controller 180 is connected to the voltage acquisition component 160 and is used to determine the target operating frequency of the microwave component 140 based on the feedback voltage value.

[0090] The aerosol generating device 100 provided in this embodiment includes a housing 120, a microwave component 140, a voltage acquisition component 160, and a controller 180. An atomization chamber 122 is disposed within the housing 120, and the atomization chamber 122 can contain an aerosol generating matrix. The microwave component 140 is mounted on the housing 120 and can feed microwaves into the atomization chamber 122. The aerosol generating matrix contained in the atomization chamber 122 can be heated and atomized under the action of the microwaves fed by the microwave component 140. Due to the resonant characteristics of the atomization chamber 122, the microwaves generated by the microwave component 140 will generate a current in the cavity wall structure of the atomization chamber 122. The voltage acquisition component 160 can acquire the feedback voltage value of the current on the cavity wall structure of the atomization chamber 122 and transmit the feedback voltage value to the controller 180. The controller 180 can determine the energy level at the cavity wall of the atomization chamber 122 based on the magnitude of the feedback voltage value.

[0091] Specifically, during the frequency sweep operation of the microwave component 140, the voltage acquisition component 160 continuously acquires the feedback voltage value on the cavity wall of the atomizing cavity 122. The controller 180 records the acquired multiple feedback voltage values ​​after the microwave component 140 completes the frequency sweep operation. The controller 180 compares the magnitudes of the multiple feedback voltage values ​​and takes the operating frequency corresponding to the largest feedback voltage value as the target operating frequency. It can be understood that a larger feedback voltage value means that the microwave at the current frequency feeds more energy into the atomizing cavity 122. Therefore, the operating frequency corresponding to the largest feedback voltage value is the resonant frequency of the atomizing cavity 122. Thus, controlling the microwave component 140 to operate at the operating frequency corresponding to the largest feedback voltage value ensures that the microwave component 140 operates at the optimal frequency point, improving the heating and atomization efficiency of the aerosol generating device 100 on the aerosol generating matrix.

[0092] For example, the microwave generator is controlled to sweep frequency within a set frequency range, with a minimum frequency of 2.2 GHz and a maximum frequency of 2.57 GHz. During the sweep, the microwave generator 140 starts from the minimum frequency and increases by 10 MHz every 2 milliseconds until the maximum frequency is reached. A feedback voltage value is recorded each time the operating frequency is switched. After the sweep is complete, the operating frequency corresponding to the maximum value of the feedback voltage is taken as the target operating frequency, and the microwave generator 140 is controlled to feed microwaves into the atomizing cavity 122 according to the target operating frequency.

[0093] In related technologies, a circulator for detecting the standing wave ratio is installed in the aerosol generating device. However, the circulator occupies a large space in the aerosol generating device, and it generates heat during operation, which reduces the efficiency of the entire system.

[0094] This embodiment incorporates a voltage acquisition component 160 within the atomization chamber 122, capable of collecting feedback voltage values ​​from the chamber wall. This enables the controller 180 to determine the current energy input within the atomization chamber 122 based on the feedback voltage value, thereby identifying the resonant frequency of the atomization chamber 122—the optimal operating frequency of the microwave component 140. Controlling the atomization component based on this optimal frequency improves the heating and atomization efficiency of the aerosol generating device 100 on the aerosol generating matrix. While ensuring the accuracy and efficiency of the detected optimal frequency of the microwave component 140, it eliminates the need for a bulky circulator within the atomization chamber 122, facilitating product miniaturization and reducing production costs. Furthermore, the voltage acquisition component 160 does not generate excessive heat during operation, ensuring the operational efficiency of the aerosol generating device 100.

[0095] In addition, the aerosol generating device 100 in the above-described technical solution provided in this embodiment may also have the following additional technical features:

[0096] like Figure 1 As shown, in any of the above embodiments, the voltage acquisition component 160 includes a power supply point 162 and a filter component 164.

[0097] The power supply point 162 is located on the inner wall of the housing 120;

[0098] The first end of the filter component 164 is connected to the power supply point 162, and the second end of the filter component 164 is connected to the controller 180.

[0099] In this embodiment, the voltage acquisition component 160 includes a power supply point 162 and a filter component 164. The power supply point 162 is set on the inner wall of the housing 120, that is, the power supply point 162 is set in the inner cavity of the atomizing chamber 122. The voltage signal at the inner side wall of the atomizing chamber 122 is acquired through the power supply point 162. The voltage signal is filtered by the filter component 164 and transmitted to the controller 180, so that the controller 180 can acquire the feedback voltage value at the atomizing chamber 122 through the power supply point 162.

[0100] When microwaves are fed into the atomizing cavity 122, a current will be generated in the cavity wall structure of the atomizing cavity 122 due to the resonant characteristics of the atomizing cavity 122. In this embodiment, a feed point 162 is set in the atomizing cavity 122 to realize the acquisition of the feedback voltage value at the cavity wall of the atomizing cavity 122.

[0101] like Figure 2 As shown, in any of the above embodiments, the filter component 164 includes a diode 1642 and a filter circuit 1644.

[0102] The first terminal of diode 1642 is connected to the feed point 162, and the second terminal of diode 1642 is grounded.

[0103] The first terminal of the filter circuit 1644 is connected to the first terminal of the diode 1642, the second terminal of the filter component 164 is connected to the second terminal of the diode 1642, and the filter circuit 1644 is connected to the controller 180.

[0104] In this configuration, the second terminal of diode 1642 is connected to the first terminal.

[0105] In this embodiment, the filter component 164 includes a diode 1642 and a filter circuit 1644. The diode 1642 is a rectifier diode 1642. The current at the inner wall of the atomizing cavity 122 is rectified into a DC signal, and the DC signal is filtered by the filter circuit 1644. The filtered DC signal is then sent to the controller 180. The controller 180 can determine the feedback voltage value at the cavity wall of the atomizing cavity 122 by receiving the filtered DC signal.

[0106] Specifically, diode 1642 is connected in parallel with filter circuit 1644. The first terminal of diode 1642 is the negative terminal of diode 1642, which is connected to feed point 162. The positive terminal of diode 1642 is connected to ground. Controller 180 is connected to rectifier circuit. The negative terminal of diode 1642 can be used to collect the feedback voltage value of the negative current on the cavity wall of atomizing cavity 122.

[0107] In this embodiment, by connecting diode 1642 and filter circuit 1644 in parallel and connecting the negative terminal of diode 1642 to feed point 162, the filter component 164 can collect the feedback voltage value of the negative current on the cavity wall of atomizing cavity 122 through feed point 162.

[0108] like Figure 3 As shown, in any of the above embodiments, the filter component 164 includes a diode 1642 and a filter circuit 1644.

[0109] The first terminal of diode 1642 is connected to feed point 162;

[0110] The first terminal of the filter circuit 1644 is connected to the second terminal of the diode 1642, the second terminal of the filter circuit 1644 is grounded, and the filter circuit 1644 is connected to the controller 180.

[0111] In this configuration, the first terminal of diode 1642 is conducting to the second terminal.

[0112] In this embodiment, the filter component 164 includes a diode 1642 and a filter circuit 1644. The diode 1642 is a rectifier diode 1642. The current at the inner wall of the atomizing cavity 122 is rectified into a DC signal, and the DC signal is filtered by the filter circuit 1644. The filtered DC signal is then sent to the controller 180. The controller 180 can determine the feedback voltage value at the cavity wall of the atomizing cavity 122 by receiving the filtered DC signal.

[0113] Specifically, diode 1642 is connected in series with filter circuit 1644. The first segment of diode 1642 is the positive terminal of diode 1642, which is connected to feed point 162. The negative terminal of diode 1642 is connected to controller 180 through rectifier circuit. The feedback voltage value of the positive current on the cavity wall of atomizing cavity 122 can be collected through the positive terminal of diode 1642.

[0114] In this embodiment, by connecting diode 1642 in series with filter circuit 1644 and connecting the positive terminal of diode 1642 to feed point 162, the filter component 164 can collect the feedback voltage value of the positive current on the cavity wall of atomizing cavity 122 through feed point 162.

[0115] In any of the above embodiments, the filter circuit 1644 includes any one or a combination of the following: capacitor filter circuit 1644, resistor-capacitor filter circuit 1644, and inductor-capacitor filter circuit 1644.

[0116] In this embodiment, the filter circuit 1644 is selected as a DC filter circuit 1644, specifically it can be one or a combination of a capacitor filter circuit 1644, a resistor-capacitor filter circuit 1644 (RC), and an inductor-capacitor filter circuit 1644 (LC).

[0117] In some embodiments, the filter circuit 1644 is selected as an inductor-capacitor filter circuit 1644, and the diode 1642 is connected in series with the inductor-capacitor filter circuit 1644.

[0118] In these embodiments, the first terminal of diode 1642 is connected to feed point 162, and the second terminal of diode 1642 is connected to an inductor and a capacitor connected in series. The capacitor is connected to controller 180, and the common terminal of the capacitor and controller 180 is grounded. Diode 1642 is conducting from the first terminal to the second terminal. The current at the cavity wall of atomizing cavity 122 is rectified by diode 1642 into a DC current signal. The DC current signal is filtered by inductor-capacitor filter circuit 1644 and then transmitted to controller 180. Controller 180 processes the DC current signal to obtain a feedback voltage value.

[0119] In any of the above embodiments, the feed point 162 includes:

[0120] A through hole is provided on the bottom wall of the atomizing chamber 122, and the filter assembly 164 is connected to the wall of the through hole;

[0121] Alternatively, a conductive ring is disposed on the inner wall of the atomizing chamber 122, with the conductive ring close to the bottom wall of the atomizing chamber 122, and the filter assembly 164 is connected to the conductive ring;

[0122] Alternatively, a lead wire may be used, with the first end of the lead wire connected to the bottom wall of the atomizing chamber 122 and the second end of the lead wire connected to the filter assembly 164.

The conductive ring can guide the current at the cavity wall to the filter component 164, thereby acquiring the feedback voltage value at the cavity wall of the atomizing cavity 122 through the conductive ring.

[0126] Example 2:

[0127] like Figure 4 As shown, a control method for an aerosol generating device is provided in a second embodiment of the present invention.

[0128] The aerosol generating device includes a microwave component, an atomizing cavity, and a voltage acquisition component.

[0129] Control methods for aerosol generating devices include:

[0130] Step 402: Control the microwave component to sweep frequency within the set frequency range;

[0131] Step 404: While the microwave component is in frequency sweep operation, multiple feedback voltage values ​​of the atomizing cavity are acquired through the voltage acquisition component.

[0132] Step 406: Determine the target frequency within the set frequency range based on multiple feedback voltage values;

[0133] Step 408: Control the microwave components to operate at the target frequency.

[0134] The control method for the aerosol generating device provided in this embodiment controls the aerosol generating device, which includes a housing, a microwave component, a voltage acquisition component, and a controller. An atomization chamber is provided inside the housing, capable of containing the aerosol generating matrix. The microwave component is mounted on the housing and can feed microwaves into the atomization chamber. The aerosol generating matrix contained in the atomization chamber is heated and atomized under the action of the microwaves fed by the microwave component. Due to the resonant characteristics of the atomization chamber, the microwaves generated by the microwave component induce a current in the cavity wall structure of the atomization chamber.

[0135] With the aerosol generating matrix located within the atomization chamber, the microwave component is controlled to begin frequency sweeping within a set frequency range. During this sweeping operation, multiple feedback voltage values ​​at the chamber wall are continuously acquired by a voltage acquisition component. These feedback voltage values ​​correspond to multiple operating frequencies during the microwave component's frequency sweep. By analyzing these feedback voltage values, the target frequency within the set frequency range can be obtained. The microwave component is then controlled to feed microwaves into the atomization chamber at the target frequency to heat and atomize the aerosol generating matrix within the chamber.

[0136] Understandably, by acquiring feedback voltage values ​​during frequency sweeping and determining the target frequency based on these values, the target frequency is the operating frequency closest to the cavity's resonant frequency within the radio frequency range—that is, the optimal frequency point for the microwave component during operation. By controlling the aerosol generating device to feed microwaves into the atomization cavity at the target frequency, the atomization efficiency of the aerosol generating matrix within the atomization cavity can be improved.

[0137] In related technologies, a circulator for detecting the standing wave ratio is installed in the aerosol generating device. However, the circulator occupies a large space in the aerosol generating device, and it generates heat during operation, which reduces the efficiency of the entire system.

[0138] This invention incorporates a voltage acquisition component within the atomization chamber, capable of collecting feedback voltage values ​​from the chamber walls. This allows the controller to determine the current energy input within the atomization chamber based on the feedback voltage, thereby identifying the chamber's resonant frequency—the optimal operating frequency of the microwave component. Controlling the atomization component according to this optimal frequency improves the heating and atomization efficiency of the aerosol generation device on the aerosol-generating matrix. While ensuring the accuracy and efficiency of detecting the optimal frequency of the microwave component, it eliminates the need for a bulky circulator within the atomization chamber, facilitating product miniaturization, reducing production costs, and ensuring the efficient operation of the aerosol generation device by miniaturizing the voltage acquisition component during operation.

[0139] like Figure 5As shown, in any of the above embodiments, determining the target frequency within the set frequency range based on the feedback voltage value further includes:

[0140] Step 502: Obtain the maximum voltage value among multiple feedback voltage values;

[0141] Step 504: Determine the target frequency corresponding to the maximum voltage value within the set frequency range based on the maximum voltage value.

[0142] In this embodiment, during the frequency sweep operation of the microwave component, the voltage acquisition component continuously acquires the feedback voltage values ​​on the cavity wall of the atomization cavity. The controller records the acquired multiple feedback voltage values. After the microwave component completes the frequency sweep operation, the controller compares the magnitudes of the multiple feedback voltage values ​​and uses the operating frequency corresponding to the maximum voltage value among the multiple feedback voltage values ​​as the target operating frequency.

[0143] It is understandable that a large feedback voltage value means that the microwave at the current frequency feeds more energy into the atomization cavity. Therefore, the operating frequency corresponding to the largest voltage value among multiple feedback voltage values ​​is the target frequency in the radio frequency range. Thus, controlling the microwave component to operate at the operating frequency corresponding to the largest feedback voltage value can ensure that the microwave component operates at the optimal frequency point, thereby improving the heating and atomization efficiency of the aerosol generation device on the aerosol generation matrix.

[0144] like Figure 6 As shown, in any of the above embodiments, controlling the microwave component to operate within a set frequency range includes:

[0145] Step 602: Control the microwave component to start operating at a first frequency within the set frequency range;

[0146] Step 604: At each first set time interval, adjust the operating frequency of the microwave component according to the set adjustment value until the operating frequency reaches the second frequency within the set frequency range.

[0147] In this embodiment, the microwave component is controlled to operate by sweeping frequencies within a set frequency range. Specifically, the microwave component is controlled to start operating at a first frequency, which is lower than the set frequency range. After a first set time interval, the microwave component is controlled to adjust its operating frequency by a set adjustment value until it is adjusted to a second frequency within the set frequency range.

[0148] It is understandable that the first frequency is greater than the second frequency, or the first frequency is less than the second frequency. That is, during frequency sweep operation, the microwave component can operate by increasing the frequency from low to high within the set frequency range, or by decreasing the frequency from high to low within the set frequency range.

[0149] For example, the microwave generator is controlled to sweep frequency within a set frequency range, with a minimum frequency of 2.2 GHz and a maximum frequency of 2.57 GHz. During the sweep, the microwave generator starts from the minimum frequency and increases by 10 MHz every 2 milliseconds until the maximum frequency is reached. A feedback voltage value is recorded each time the operating frequency is switched. After the sweep is complete, the operating frequency corresponding to the maximum value of the feedback voltage is taken as the target operating frequency, and the microwave generator is controlled to feed microwaves into the atomization cavity according to the target operating frequency.

[0150] This invention adjusts the set adjustment value every first set time period by controlling the operating frequency of the microwave component, so that the microwave component has enough time to feed microwaves into the atomization cavity at each operating frequency. This improves the correspondence between multiple feedback voltage values ​​and multiple operating frequencies within the set frequency range, thereby improving the accuracy of obtaining the target frequency.

[0151] In any of the above embodiments, when the microwave component is in the frequency sweep operation state, multiple feedback voltage values ​​of the atomizing cavity are collected by the voltage acquisition component, including: when the microwave component is in operation, the feedback voltage value of the atomizing cavity is collected every first set time interval.

[0152] In this embodiment, during the frequency sweep operation, the feedback voltage value of the atomizing cavity is collected once at a first set time interval. By corresponding the time of collecting the feedback voltage value with the time of adjusting the operating frequency during the frequency sweep operation of the microwave component, the multiple collected feedback voltage values ​​can be matched one-to-one with the operating frequencies in the set frequency range, which makes it easier to find the accurate target frequency based on the maximum voltage value among the multiple feedback voltage values.

[0153] In some embodiments, the voltage acquisition component continuously detects the feedback voltage value of the atomizing chamber and records the current feedback voltage value every first set time interval.

[0154] In other implementations, the voltage acquisition component detects and records the current feedback voltage value at first set intervals.

[0155] In any of the above embodiments, after controlling the microwave component to operate at the target frequency, the method further includes: when the microwave component operates at the target frequency for a second set time, returning to the step of controlling the microwave component to sweep the frequency within the set frequency range until a stop operation command is received.

[0156] In this embodiment, after determining the target frequency, the microwave component is controlled to run at the target frequency for a second set duration, and then the process returns to the step of controlling the microwave component to sweep the frequency to find the target frequency. Since the aerosol generating matrix in the aerosol generating device is heated and atomized as the microwave component operates, the aerosol generating matrix in the atomization cavity changes, causing a change in the resonant frequency of the atomization cavity. Therefore, by controlling the microwave component to run at the target frequency for a second set duration and then returning to find the target frequency, this invention continuously updates the target frequency of the microwave component, ensuring that the microwave component in the aerosol generating device can operate at the optimal frequency point for a long time, thus improving the atomization effect of the aerosol generating device on the aerosol generating matrix.

[0157] like Figure 7 As shown, in the process of microwave component control, the operation of the microwave component is controlled by closed-loop control of feedback voltage value.

[0158] The controller collects the feedback voltage value of the cavity, determines the target frequency based on the feedback voltage value, and controls the microwave component to operate at the target frequency. The microwave is fed into the atomizing cavity after passing through the microwave amplifier and coupler.

[0159] Example 3:

[0160] like Figure 8 As shown, in the third embodiment of the present invention, a control device 800 for an aerosol generating device is provided, wherein the aerosol generating device includes a microwave component, an atomizing cavity, and a voltage acquisition component.

[0161] The control device for the aerosol generating apparatus includes:

[0162] Control module 802 is used to control the microwave components to sweep frequency operation within a set frequency range;

[0163] The acquisition module 804 is used to acquire multiple feedback voltage values ​​of the atomizing cavity through the voltage acquisition component when the microwave component is in the frequency sweep operation state.

[0164] The determination module 806 is used to determine the target frequency within a set frequency range based on multiple feedback voltage values;

[0165] The control module 802 is used to control the microwave components to operate at the target frequency.

[0166] The control device for the aerosol generating apparatus provided in this embodiment controls the aerosol generating apparatus. The aerosol generating apparatus includes a housing, a microwave component, a voltage acquisition component, and a controller. An atomization chamber is provided inside the housing, which can contain the aerosol generating matrix. The microwave component is mounted on the housing and can feed microwaves into the atomization chamber. The aerosol generating matrix contained in the atomization chamber can be heated and atomized under the action of the microwaves fed by the microwave component. Due to the resonant characteristics of the atomization chamber, the microwaves generated by the microwave component will induce a current in the cavity wall structure of the atomization chamber.

[0167] With the aerosol generating matrix located within the atomization chamber, the microwave component is controlled to begin frequency sweeping within a set frequency range. During this sweeping operation, multiple feedback voltage values ​​at the chamber wall are continuously acquired by a voltage acquisition component. These feedback voltage values ​​correspond to multiple operating frequencies during the microwave component's frequency sweep. By analyzing these feedback voltage values, the target frequency within the set frequency range can be obtained. The microwave component is then controlled to feed microwaves into the atomization chamber at the target frequency to heat and atomize the aerosol generating matrix within the chamber.

[0168] Understandably, by acquiring feedback voltage values ​​during frequency sweeping and determining the target frequency based on these values, the target frequency is the operating frequency closest to the cavity's resonant frequency within the radio frequency range—that is, the optimal frequency point for the microwave component during operation. By controlling the aerosol generating device to feed microwaves into the atomization cavity at the target frequency, the atomization efficiency of the aerosol generating matrix within the atomization cavity can be improved.

[0169] In related technologies, a circulator for detecting the standing wave ratio is installed in the aerosol generating device. However, the circulator occupies a large space in the aerosol generating device, and it generates heat during operation, which reduces the efficiency of the entire system.

[0170] This invention incorporates a voltage acquisition component within the atomization chamber, capable of collecting feedback voltage values ​​from the chamber walls. This allows the controller to determine the current energy input within the atomization chamber based on the feedback voltage, thereby identifying the chamber's resonant frequency—the optimal operating frequency of the microwave component.

While ensuring the accuracy and efficiency of detecting the optimal frequency of the microwave component, it eliminates the need for a bulky circulator within the atomization chamber, facilitating product miniaturization, reducing production costs, and ensuring the efficient operation of the aerosol generation device by miniaturizing the voltage acquisition component during operation.

[0171] In any of the above embodiments, the control device for the aerosol generating apparatus further includes:

[0172] The acquisition module is used to acquire the maximum voltage value among multiple feedback voltage values;

[0173] The determining module 806 is also used to determine the target frequency corresponding to the maximum voltage value within a set frequency range based on the maximum voltage value.

[0174] In this embodiment, during the frequency sweep operation of the microwave component, the voltage acquisition component continuously acquires the feedback voltage values ​​on the cavity wall of the atomization cavity. The controller records the acquired multiple feedback voltage values. After the microwave component completes the frequency sweep operation, the controller compares the magnitudes of the multiple feedback voltage values ​​and uses the operating frequency corresponding to the maximum voltage value among the multiple feedback voltage values ​​as the target operating frequency.

[0175] It is understandable that a large feedback voltage value means that the microwave at the current frequency feeds more energy into the atomization cavity. Therefore, the operating frequency corresponding to the largest voltage value among multiple feedback voltage values ​​is the target frequency in the radio frequency range. Thus, controlling the microwave component to operate at the operating frequency corresponding to the largest feedback voltage value can ensure that the microwave component operates at the optimal frequency point, thereby improving the heating and atomization efficiency of the aerosol generation device on the aerosol generation matrix.

[0176] In any of the above embodiments, the control module 802 is further configured to control the microwave component to start operating at a first frequency within a set frequency range;

[0177] The control module 802 is also used to adjust the operating frequency of the microwave component according to the set adjustment value at each first set time interval until the operating frequency reaches the second frequency within the set frequency range.

[0178] In this embodiment, the microwave component is controlled to operate by sweeping frequencies within a set frequency range. Specifically, the microwave component is controlled to start operating at a first frequency, which is lower than the set frequency range. After a first set time interval, the microwave component is controlled to adjust its operating frequency by a set adjustment value until it is adjusted to a second frequency within the set frequency range.

[0179] It is understandable that the first frequency is greater than the second frequency, or the first frequency is less than the second frequency. That is, during frequency sweep operation, the microwave component can operate by increasing the frequency from low to high within the set frequency range, or by decreasing the frequency from high to low within the set frequency range.

[0180] For example, the microwave generator is controlled to sweep frequency within a set frequency range, with a minimum frequency of 2.2 GHz and a maximum frequency of 2.57 GHz. During the sweep, the microwave generator starts from the minimum frequency and increases by 10 MHz every 2 milliseconds until the maximum frequency is reached. A feedback voltage value is recorded each time the operating frequency is switched. After the sweep is complete, the operating frequency corresponding to the maximum value of the feedback voltage is taken as the target operating frequency, and the microwave generator is controlled to feed microwaves into the atomization cavity according to the target operating frequency.

[0181] This invention adjusts the set adjustment value every first set time period by controlling the operating frequency of the microwave component, so that the microwave component has enough time to feed microwaves into the atomization cavity at each operating frequency. This improves the correspondence between multiple feedback voltage values ​​and multiple operating frequencies within the set frequency range, thereby improving the accuracy of obtaining the target frequency.

[0182] In any of the above embodiments, the acquisition module 804 is further configured to acquire the feedback voltage value of the atomizing cavity every first set time interval when the microwave component is in operation.

[0183] In this embodiment, during the frequency sweep operation, the feedback voltage value of the atomizing cavity is collected once at a first set time interval. By corresponding the time of collecting the feedback voltage value with the time of adjusting the operating frequency during the frequency sweep operation of the microwave component, the multiple collected feedback voltage values ​​can be matched one-to-one with the operating frequencies in the set frequency range, which makes it easier to find the accurate target frequency based on the maximum voltage value among the multiple feedback voltage values.

[0184] In any of the above embodiments, the control module 802 is further configured to return to the step of controlling the microwave component to sweep the frequency within the set frequency range when the microwave component has been running at the target frequency for a second set time, until a stop operation command is received.

[0185] In this embodiment, after determining the target frequency, the microwave component is controlled to run at the target frequency for a second set duration, and then the process returns to the step of controlling the microwave component to sweep the frequency to find the target frequency. Since the aerosol generating matrix in the aerosol generating device is heated and atomized as the microwave component operates, the aerosol generating matrix in the atomization cavity changes, causing a change in the resonant frequency of the atomization cavity. Therefore, by controlling the microwave component to run at the target frequency for a second set duration and then returning to find the target frequency, this invention continuously updates the target frequency of the microwave component, ensuring that the microwave component in the aerosol generating device can operate at the optimal frequency point for a long time, thus improving the atomization effect of the aerosol generating device on the aerosol generating matrix.
