[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202410318437.3, filed on March 19, 2024, entitled “Microwave control method, atomization equipment and storage medium for aerosol generating device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of electronic atomization equipment, and in particular to a microwave control method for an aerosol generating device, an atomization device, and a storage medium. Background Art

[0004] The core components of an electronic atomization device include an MCU (Micro Control Unit), a power supply, an aerosol generator, and a heating element mounted on the aerosol generator. The MCU uses the power supply to transmit electrical energy to the heating element, causing it to heat up. The heat emitted by the heating element heats the aerosol generator and generates aerosol, which is then inhaled by the user. In related technologies, in addition to using the heat emitted by the heating element to heat the aerosol generator, microwaves (a type of electromagnetic wave) can also be used to heat the aerosol generator, which has the advantages of high heating efficiency and speed. However, when using microwaves to heat an aerosol generator, it is necessary to provide high-power, high-frequency microwaves within the pulse time. Although high-power, high-frequency microwaves can instantly increase the temperature of the aerosol generator to a level that can atomize aerosols, or in other words, can instantly increase the electrical power of the heated aerosol generator to a level that can atomize aerosols, this instantaneous increase will reduce the service life of the electronic atomization device. At the same time, high-power, high-frequency microwaves will also bring about defects such as electromagnetic exposure, electromagnetic compatibility, and local overheating of the impedance mutation part of the microwave source or microwave radiator. Furthermore, if you want to improve the above defects, you need to extend the heating time of the aerosol generator, that is, extend the time it takes for the electrical power of the heated aerosol generator to reach a level that can atomize aerosols. Although this time extension method improves the above defects, it cannot guarantee the original pump-and-stop function of the electronic atomization device. Therefore, it is necessary to improve the existing microwave heating scheme for aerosol generators.

[0005] Summary of the Invention

[0006] The present application provides a microwave control method, atomization equipment and storage medium for an aerosol generating device, which solves the problem of insufficient service life of electronic atomization equipment caused by the instantaneous increase in electric power / temperature when using microwaves to heat an aerosol generator in the related art.

[0007] A first aspect of an embodiment of the present application provides a microwave control method for an aerosol generating device, wherein the aerosol generating device includes a shell and a microwave radiator, an aerosol generator, a microwave generating circuit, a power amplifying circuit, a microwave output circuit and a single-chip microcomputer arranged in the shell, the aerosol generator is placed in the microwave radiator, the microwave generating circuit, the power amplifying circuit and the microwave output circuit are connected in sequence, and the microwave generating circuit and the power amplifying circuit are respectively connected to the single-chip microcomputer. Specifically, the microwave control method is applied to a single-chip microcomputer, including: obtaining palm contact data between the palm and the outer surface of the shell, and judging whether a grabbing event of the aerosol generating device occurs before inhalation based on the palm contact data; obtaining elbow movement data of the elbow during movement, and judging whether a hand-raising event of holding the aerosol generating device before inhalation occurs based on the elbow movement data; if a grabbing event and a hand-raising event occur, outputting a microwave generation instruction to the microwave generating circuit, and outputting a power amplification instruction to the power amplification circuit; wherein the microwave generation instruction is used to instruct the microwave generating circuit to output an initial microwave signal; the power amplification instruction is used to instruct the power amplification circuit to enter a conduction state allowing signal transmission, and power-amplify the initial microwave signal to obtain a target microwave signal; the target microwave signal is output by the microwave output circuit to the microwave radiator, so that the microwave radiator radiates the target microwave signal to the aerosol generator to preheat the aerosol generator before inhalation.

[0008] The second aspect of the embodiment of the present application provides an electronic atomization device, which includes an aerosol generating device, and the aerosol generating device includes a shell and a microwave radiator, an aerosol generator, a microwave generating circuit, a power amplifying circuit, a microwave output circuit and a single-chip microcomputer arranged in the shell. The aerosol generator is placed in the microwave radiator, the microwave generating circuit, the power amplifying circuit and the microwave output circuit are connected in sequence, and the microwave generating circuit and the power amplifying circuit are respectively connected to the single-chip microcomputer, which is used to control the microwave heating of the aerosol generator according to the microwave control method mentioned in the first aspect of the embodiment of the present application.

[0009] The third aspect of the embodiment of the present application provides a single-chip microcomputer, including a memory and a control and processor communicatively connected to the memory, the memory is used to store computer programs, and the control and processor is used to call and execute the computer programs to implement the microwave control method mentioned in the first aspect of the embodiment of the present application.

[0010] A fourth aspect of an embodiment of the present application provides a computer-readable storage medium on which a computer program is stored. The computer program is used to be retrieved and executed by a controller and a processor to implement the microwave control method mentioned in the first aspect of the embodiment of the present application.

[0011] Through the implementation of the above technical solutions of the present application, the single-chip microcomputer can obtain the palm contact data between the user's palm and the outer surface of the shell of the aerosol generating device, and the elbow movement data of the user's elbow during the movement process, and judge whether the user has grasped the aerosol generating device before inhalation based on the palm contact data, and judge whether the user has raised his hand to hold the aerosol generating device before inhalation based on the elbow movement data. Once the grasping event and hand-raising event before inhalation are determined, the single-chip microcomputer will send a microwave generation instruction to the microwave generating circuit to instruct the microwave generating circuit to generate an initial microwave signal, and send a power amplification instruction to the power amplifier circuit to instruct the power amplifier circuit to enter a conduction state allowing signal transmission and amplify the initial microwave signal to obtain a target microwave signal. Finally, the microwave output circuit outputs the target microwave signal to the microwave radiator, so that the microwave radiator radiates the target microwave signal to the aerosol generator to preheat the aerosol generator before inhalation. It can be seen from this that the microwave generating circuit will not generate an initial microwave signal when it does not receive the microwave generating instruction sent by the single-chip microcomputer, and the power amplifying circuit will not allow signal transmission when it does not receive the power amplifying instruction sent by the single-chip microcomputer, that is, it will not allow any signal (such as the initial microwave signal) to be transmitted through itself to the microwave output circuit, and of course it will not power amplify any signal. Before inhaling, the user will inevitably hold the aerosol generating device and move it to his lips. During the movement, the user's elbow will inevitably move. Based on this, when the application determines that the user grabs the aerosol generating device and raises his hand according to the palm contact data and elbow movement data, it can be considered that the user will inhale in a short period of time afterwards. Then before the user inhales (that is, before the user raises his hand), In the process of the user holding the aerosol generating device and raising his hand), the present application will control the microwave generating circuit to generate an initial microwave signal, and control the power amplifier circuit to enter a conductive state allowing signal transmission, so as to use the power amplifier circuit to amplify the power of the transmitted initial microwave signal and obtain a target microwave signal accordingly. The obtained target microwave signal will be output by the power amplifier circuit to the microwave radiator, thereby realizing preheating of the aerosol generator before the user inhales, thereby avoiding the instantaneous heating phenomenon of the aerosol generator when the user inhales in the traditional scheme (that is, the temperature of the aerosol generator instantly rises to a level that can atomize out aerosol, or in other words, the electric power for heating the aerosol generator instantly rises to a level that can atomize out aerosol), thereby improving the service life of the electronic atomization device.

[0022] In order to make the purpose, technical solutions and advantages of the present application more obvious and easy to understand, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. It should be understood that the various embodiments of the present application described below are only used to explain the present application and are not used to limit the present application, that is, based on the various embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0023] In the related art, when using microwaves to heat the aerosol generator, it is necessary to provide high-power, high-frequency microwaves within the pulse time. Although high-power, high-frequency microwaves can instantly increase the temperature of the aerosol generator to a level that can atomize out the aerosol, or in other words, can instantly increase the electric power of heating the aerosol generator to a level that can atomize out the aerosol, this instantaneous increase phenomenon will reduce the service life of the electronic atomization device. At the same time, high-power, high-frequency microwaves will also bring about defects such as electromagnetic exposure, electromagnetic compatibility, and local overheating of the impedance mutation part of the microwave source or microwave radiator. Furthermore, if you want to improve the above defects, you need to extend the heating time of the aerosol generator, that is, extend the time for the electric power of heating the aerosol generator to reach a level that can atomize out the aerosol. Although this time extension method improves the above defects, it cannot guarantee the original pump-and-stop function of the electronic atomization device. To this end, the present application proposes a microwave control method for an aerosol generating device in the following embodiments to control the entire process of microwave heating of the aerosol generator. It adds a step of preheating the aerosol generator before the user inhales, which can avoid the instantaneous increase in electric power / temperature in traditional schemes, thereby improving the service life of the electronic atomization device; at the same time, the microwave control method can also monitor in real time whether there is a hidden danger of electromagnetic exposure during the user's inhalation process. Once the hidden danger of electromagnetic exposure is detected, the microwave control method can take corresponding safety actions in time (such as cutting off the power supply), thereby ensuring the user's life safety.

[0024] The aerosol generating device in the electronic atomization device includes a shell, a microwave radiator and an aerosol generator. The microwave radiator and the aerosol generator are both arranged in the shell. The microwave radiator serves as a container for the aerosol generator. The microwave radiator can receive microwave signals and radiate the received microwave signals to the aerosol generator to heat the aerosol generator. When the temperature of the aerosol generator rises to a certain value after being heated, it will atomize an aerosol. The aerosol generated can be inhaled by the user. Preferably, the aerosol generator is arranged in the microwave radiator. Of course, this is only one assembly form of the two. In fact, the aerosol generator can also be arranged on or outside the microwave radiator, as long as the microwave radiator can radiate the microwave signal it receives to the aerosol generator and heat the aerosol generator to generate aerosol. In addition, it should be noted that the aerosol generating device is a core component of the electronic atomization device. Usually, the shell of the aerosol generating device also serves as the outer shell of the electronic atomization device.

[0025] Figure 1 is a structural block diagram of an aerosol generating device. In some embodiments, in addition to the structures listed above, the aerosol generating device also includes a microwave generating circuit 110, a power amplifier circuit 120, a microwave output circuit 130 and a single-chip microcomputer 140 arranged in a shell. The microwave generating circuit 110, the power amplifier circuit 120 and the microwave output circuit 130 are connected in sequence, and the microwave generating circuit 110 and the power amplifier circuit 120 are respectively connected to the single-chip microcomputer 140. The single-chip microcomputer 140 plays a data processing and control role in this application, and the microwave control method of the present application is essentially a computer program stored in the single-chip microcomputer 140. The single-chip microcomputer 140 can control the entire microwave heating process of the aerosol generator by executing the computer program. Specifically, during the actual microwave heating control process, the single-chip microcomputer 140 can obtain the palm contact data between the user's palm and the outer surface of the shell of the aerosol generating device, and the elbow movement data of the user's elbow during the movement process, and judge whether the user has grasped the aerosol generating device before inhalation based on the palm contact data, and judge whether the user has raised his hand to hold the aerosol generating device before inhalation based on the elbow movement data. Once the grasping event and the hand-raising event before inhalation are determined to have occurred, the single-chip microcomputer 140 will send a microwave generation instruction to the microwave generating circuit 110 and a power amplification instruction to the power amplifier circuit 120. The microwave generation instruction can instruct the microwave generating circuit 110 to output an initial microwave signal, and the power amplification instruction can instruct the power amplifier circuit 120 to enter a conductive state allowing signal transmission, and amplify the power of the initial microwave signal to obtain a target microwave signal. Finally, the microwave output circuit 130 outputs the target microwave signal to the microwave radiator, so that the microwave radiator radiates the target microwave signal to the aerosol generator to pre-heat the aerosol generator before inhalation. Preferably, the microwave generating circuit 110 of the present application has the ability to self-regulate the output frequency, that is, the microwave generating circuit 110 can adjust its own output frequency between 0.5 and 20 GHz according to the resonant frequency of the load after the aerosol generator is inserted into the microwave radiator.

[0026] It is understandable that the microwave generating circuit 110 will not generate an initial microwave signal when it does not receive the microwave generating instruction sent by the single-chip microcomputer 140, and the power amplifying circuit 120 will not allow signal transmission when it does not receive the power amplifying instruction sent by the single-chip microcomputer 140, that is, it does not allow any signal (such as the initial microwave signal) to be transmitted to the microwave output circuit 130 through itself, and of course it will not power amplify any signal. Before inhaling, the user will inevitably hold the aerosol generating device and move the aerosol generating device to his lips. During the movement, the user's elbow will inevitably move. Based on this, when the application determines that the user grabs the aerosol generating device and raises his hand based on the palm contact data and the elbow movement data, it can be considered that the user will inhale in a short period of time afterwards. Then, before the user inhales (that is, when the user holds the aerosol generating device In the process of raising the hand), the present application will control the microwave generating circuit 110 to generate an initial microwave signal, and control the power amplifier circuit 120 to enter a conductive state allowing signal transmission, so as to use the power amplifier circuit 120 to amplify the power of the transmitted initial microwave signal and obtain the target microwave signal accordingly. The obtained target microwave signal will be output to the microwave radiator by the power amplifier circuit 120, and the microwave radiator will radiate the target microwave signal it receives to the aerosol generator, thereby realizing preheating of the aerosol generator before the user inhales, thereby avoiding the instantaneous heating phenomenon of the aerosol generator when the user inhales in the traditional scheme (that is, the temperature of the aerosol generator instantly rises to a level that can atomize out aerosol, or in other words, the electric power for heating the aerosol generator instantly rises to a level that can atomize out aerosol), thereby improving the service life of the electronic atomization device.

[0027] As one embodiment, please refer to Figure 1. The single-chip microcomputer 140 includes a memory 141 and a control and processor 142. The memory 141 is communicatively connected to the control and processor 142. A computer program is stored in the memory 141. The computer program is actually the microwave control method of the present application. That is, the control and processor 142 can call and execute the computer program stored in the memory 141 to implement the microwave control method. In some implementations of this embodiment, the control and processor 142 is provided with several functional units, and different functional units have different functions. Through the collaboration between the several functional units, the data processing and control functions of the control and processor 142 as a whole can be realized; illustratively, the control and processor 142 is provided with a first feedback unit, a second feedback unit and a control unit, the first feedback unit can obtain palm contact data and transmit it to the control unit, the second feedback unit can obtain elbow motion data and transmit it to the control unit, the control unit can determine whether a grabbing event occurs before the user puffs based on the palm contact data, and determine whether a hand-raising event occurs before the user puffs based on the elbow motion data, and when it is determined that a grabbing event and a hand-raising event occur before the user puffs, the control unit outputs a microwave generation instruction to the microwave generating circuit 110 and sends a power amplification instruction to the power amplification circuit 120; it can be understood that as to which functional units are provided in the control and processor 142, what functions these functional units respectively have and how these functional units collaborate, etc., they can all be designed according to actual needs, and this application will not elaborate on them here. In some implementations of this embodiment, the memory 141 includes at least one type of computer-readable storage medium, which may include but is not limited to flash memory, a mobile hard disk, a multimedia card, a card-type memory (such as SD memory, DX memory, etc.), a magnetic memory, a disk, and an optical disk.

[0028] The above embodiments are only preferred implementations of the present application. They are not the only limitations on the aerosol generating device, the single-chip microcomputer 140, and other related contents. In this regard, those skilled in the art can flexibly set them according to the actual application scenarios based on the above embodiments. Below, the computer program (i.e., the microwave control method) executed by the control and processor 142 in the single-chip microcomputer 140 will be described in detail. Figure 2 is a flow chart of the microwave control method. In some embodiments, the microwave control method includes the following steps 201 to 203 (abbreviated as S201 to S203). In the steps below, this application will describe the control and processor 142 in the single-chip microcomputer 140 as the execution subject, and will no longer consider the various functional units in the control and processor 142.

[0029] S201 , obtaining palm contact data between a palm and an outer surface of a housing, and determining whether a grabbing event of the aerosol generating device before inhalation occurs based on the palm contact data.

[0030] In some embodiments, when controlling the microwave heating of the aerosol generator, the control and processor 142 needs to obtain palm contact data between the user's palm and the outer surface of the shell of the aerosol generating device, and determine whether the user has grasped the aerosol generating device before inhaling based on the palm contact data.

[0031] As one embodiment, please refer to Figure 1. A first sensor cluster 150 is provided on the outer surface of the shell. The first sensor cluster 150 is composed of a plurality of first sensors distributed at different positions. Each first sensor in the first sensor cluster 150 is embedded inward from the outer surface of the shell. The purpose is to ensure the smoothness of the outer surface of the shell and avoid a rough feeling when the user holds the aerosol generating device. The first sensor cluster 150 can collect palm contact data in real time by relying on its own plurality of first sensors, and transmit the collected palm contact data to the control and processor 142 in the single-chip microcomputer 140. In some implementations of this embodiment, some of the first sensors in the first sensor cluster 150 use pressure sensors and other part of the first sensors use temperature sensors. Based on this, when the user holds the aerosol generating device, the pressure of the part covered by the user's palm on the outer surface of the shell can be obtained through each pressure sensor, and the temperature of the part covered by the user's palm on the outer surface of the shell can be obtained through each temperature sensor. At the same time, the area of ​​the part covered by the user's palm on the outer surface of the shell can be calculated by detecting the pressure at which pressure sensors on the shell are located. That is to say, the palm contact data of the present application at least includes the area data, pressure data and temperature data of the part covered by the user's palm on the outer surface of the shell.

[0032] Furthermore, the user will inevitably grasp the aerosol generating device before taking a puff. For this pre-puff grasping, the contact area, pressure, temperature between the user's palm and the outer surface of the housing, and the duration of the user's grasping of the aerosol generating device all conform to certain rules. For example, the grasping duration should not be too short, the contact area and pressure between the palm and the outer surface of the housing should not be too small, and the temperature between the palm and the outer surface of the housing should be close to the palm's body surface temperature. In view of this, the process by which the control and processor 142 determines whether a pre-puff grasping event of the aerosol generating device has occurred based on palm contact data includes: determining whether at least two of the area data, pressure data, and temperature data are greater than their respective preset thresholds, and whether the duration of the grasping period is within a preset time range; if so, determining that a grasping event has occurred. Exemplarily, if the area data is greater than a preset area threshold and the pressure data is greater than a preset pressure threshold within a preset confidence interval, then a grab event is determined to have occurred; or, if the pressure data is greater than a preset pressure threshold within a preset confidence interval, the temperature data is greater than a preset temperature threshold, and the time when the temperature data is greater than the preset temperature threshold is within a preset time range, then a grab event is determined to have occurred.

[0033] Of course, it is also possible to determine whether a grab event before inhalation has occurred based on a combination of area data, pressure data, and temperature data. FIG3 is a flow diagram of S201 in FIG2 . The process for the control and processor 142 to determine whether a grab event of the aerosol generating device before inhalation has occurred based on the palm contact data includes steps 2011 to 2014 (abbreviated as S2011 to S2014), namely: S2011, determining whether the area data is greater than a preset area threshold; S2012, determining whether the pressure data is greater than a preset pressure threshold within a preset confidence interval; S2013, determining whether the temperature data is greater than a preset temperature threshold, and whether the time when the temperature data is greater than the preset temperature threshold is within a preset time range; S2014, if the area data is greater than the preset area threshold, the pressure data is greater than the preset pressure threshold within a preset confidence interval, the temperature data is greater than the preset temperature threshold, and the time when the temperature data is greater than the preset temperature threshold is within a preset time range, then it is determined that a grab event has occurred. It can be understood that the conditions for the occurrence of a grab event are determined according to actual needs, and this application does not make a sole limitation on this. Preferably, the preset area threshold is set to 70% of the outer surface area of ​​the shell, the preset confidence interval is set to 95%, the preset pressure threshold is set to 0.02 Pa, the preset temperature threshold is set to the surface temperature of the palm, and the preset time range is set to 0 to 1s.

[0034] S202, obtaining elbow motion data during the elbow motion process, and determining whether a hand-raising event of holding the aerosol generating device before inhalation occurs based on the elbow motion data.

[0035] In some embodiments, when controlling the microwave heating of the aerosol generator, the control and processor 142 not only needs to determine whether an event of grabbing the aerosol generating device before inhalation occurs, but also needs to determine whether an event of raising the hand to hold the aerosol generating device before inhalation occurs. That is, the control and processor 142 also needs to obtain the elbow movement data of the user's elbow during the movement, and determine whether an event of raising the hand to hold the aerosol generating device before inhalation occurs based on the elbow movement data.

[0036] As one embodiment, referring to FIG1 , a second sensor cluster 160 is provided on the outer surface of the housing. The second sensor cluster 160 is composed of a plurality of second sensors distributed at different positions. Each second sensor in the second sensor cluster 160 is embedded inward from the outer surface of the housing. The purpose is to ensure the smoothness of the outer surface of the housing and avoid a scratchy feeling when the user holds the aerosol generating device. The second sensor cluster 160 can use its own plurality of second sensors to collect elbow motion data in real time and transmit the collected elbow motion data to the control and processor 142 within the single-chip microcomputer 140. In some implementations of this embodiment, the second sensor cluster 160 includes at least two second sensors, one of which is an acceleration sensor and the other is a gyroscope. Based on this, when the user holds the aerosol generating device and raises his hand, not only the acceleration of the user's elbow can be obtained by the acceleration sensor, but also the pitch angle of the user's elbow can be obtained by the gyroscope. In other words, the elbow motion data of the present application includes at least the acceleration data and the pitch angle data of the user's elbow. In addition, it should be noted that the second sensor in the second sensor cluster 160 is not limited to conventional sensors such as accelerometers and gyroscopes. Doppler microwave sensors can also be used. In this way, the accuracy of motion capture and posture recognition can be improved through the inherent characteristics of Doppler microwave sensors.

[0037] Furthermore, before taking a puff, the user will inevitably grasp the aerosol generating device and raise their hand. During this process, their elbow will inevitably move. The user's purpose for this pre-puff hand-raising action is to move the aerosol generating device to their lips for inhalation, and this movement takes a certain amount of time. In other words, when the user holds the aerosol generating device and raises their hand, their elbow must conform to certain motion patterns. For example, the elbow's acceleration and pitch angle cannot be too small, and the time it takes to raise the hand and move the aerosol generating device cannot be too short. In view of this, the control and processor 142 determines whether a pre-puff hand-raising event has occurred based on elbow motion data. The process includes: determining whether at least one of the acceleration data and the pitch angle data is greater than a corresponding preset threshold value for a preset time period; if so, determining that a hand-raising event has occurred. For example, if the acceleration data enters a preset acceleration range for a preset time period, then a hand-raising event is determined to have occurred; or, if the pitch angle data exceeds a preset pitch angle threshold for a preset time period, then a hand-raising event is determined to have occurred.

[0038] Of course, it is also possible to determine whether a hand-raising event before inhalation occurs based on a combination of acceleration data and pitch angle data. FIG4 is a flow chart of S202 in FIG2 . The process for the control and processor 142 to determine whether a hand-raising event of holding the aerosol generating device before inhalation occurs based on the elbow motion data includes steps 2021 to 2023 (abbreviated as S2021 to S2023), namely: S2021, determining whether the acceleration data enters a preset acceleration range within a preset time length; S2022, determining whether the pitch angle data exceeds a preset pitch angle threshold within a preset time length; S2023, if the acceleration data enters a preset acceleration range within a preset time length and the pitch angle data exceeds a preset pitch angle threshold within a preset time length, then determining that a hand-raising event occurs. It is understandable that the conditions for the occurrence of the hand-raising event in this application are determined based on actual needs, and this application does not make a sole limitation on this. Preferably, the preset time duration is set to 0 to 5 seconds, the preset acceleration range is set to 0.9 to 2 m / s2, and the preset pitch angle threshold is set to a 90° offset.

[0039] Through the two embodiments in S201 and S202, it can be seen that the control and processor 142 of the present application obtains multimodal sensor information, namely palm contact data (area data, pressure data, and temperature data of the portion of the outer surface of the shell covered by the user's palm) and elbow movement data (acceleration data and pitch angle data of the user's elbow), and by fusing the multimodal sensor information, it is determined whether the user has grasped the aerosol generating device before inhalation and raised their hand to hold the aerosol generating device. Finally, the corresponding microwave generation instruction is output to the microwave generation circuit 110, and the corresponding power amplification instruction is output to the power amplification circuit 120. In other words, the control and processor 142 of the present application is based on multimodal fusion technology when operating, so the control and processor 142 can realize its own functions through certain multimodal fusion models, such as multi-Bayesian estimation models, artificial neural network models, etc.

[0040] S203: If a grabbing event or a hand-raising event occurs, a microwave generating instruction is output to the microwave generating circuit and a power amplifying instruction is output to the power amplifying circuit.

[0041] In some embodiments, if the control and processor 142 determines that a grabbing event and a hand-raising event have occurred before the user puffs, the control and processor 142 will send a microwave generation instruction to the microwave generating circuit 110 and a power amplification instruction to the power amplifying circuit 120. The microwave generation instruction can guide the microwave generating circuit 110 to output an initial microwave signal, and the power amplification instruction can guide the power amplifying circuit 120 to enter a conductive state and amplify the power of the initial microwave signal to obtain a target microwave signal. Finally, the microwave output circuit 130 outputs the target microwave signal to the microwave radiator, so that the microwave radiator radiates the target microwave signal to the aerosol generator to preheat the aerosol generator before puffing.

[0042] As one embodiment, Figure 5 shows a flow chart of S203 in Figure 2. When it is determined that a grabbing event and a hand-raising event have occurred before the user takes a puff, the process of the control and processor 142 outputting a power amplification instruction to the power amplification circuit 120 includes steps 2031 to 2033 (abbreviated as S2031 to S2033), namely: S2031, outputting a first power amplification instruction to the power amplification circuit; S2032, obtaining lip contact data between the lips and the outer surface of the nozzle, and judging whether a puffing event of the aerosol generating device has occurred based on the lip contact data; S2033, if a puffing event occurs, outputting a second power amplification instruction to the power amplification circuit. During the actual microwave heating process, the first power amplification instruction can instruct the power amplifier circuit 120 to enter a conductive state allowing signal transmission and adjust its own power amplification level to level 1, thereby amplifying the initial microwave signal at the level 1 power amplification level to obtain the first target microwave signal. The second power amplification instruction can instruct the power amplifier circuit 120 to adjust the power amplification level from level 1 to level 2, thereby amplifying the initial microwave signal at the level 2 power amplification level to obtain the second target microwave signal. Furthermore, it should be noted that the power of the target microwave signal is positively correlated with the power amplification level of the power amplifier circuit 120; that is, the power of the second target microwave signal is greater than the power of the first target microwave signal.

[0043] In this embodiment, when the control and processor 142 determines that a grabbing event and a hand-raising event before suction have occurred, it will output a first power amplification instruction to the power amplifier circuit 120, and the power amplifier circuit 120 can respond to the first power amplification instruction and enter a conduction state allowing signal transmission, and at the same time adjust its own power amplification level to level one, so as to power amplify the transmitted initial microwave signal at the level one power amplification level to obtain a first target microwave signal; in this application, the power of the target microwave signal is positively correlated with the power amplification level of the power amplifier circuit 120, that is, the higher the power amplification level of the power amplifier circuit 120, the greater the power of the target microwave signal. As can be seen from this, the power amplification instruction output by the control and processor 142 is not only used to turn on the power amplifier circuit 120, but also to instruct the power amplifier circuit 120 to adjust its own power amplification level, which is equivalent to adjusting the power of the output target microwave signal. The greater the power of the target microwave signal, the shorter the time it takes to atomize the aerosol when heating the aerosol generator. Since the heating of the aerosol generator performed by the control and processor 142 when determining the grab event and the hand-lift event is pre-heating before the user takes a puff, the power of the target microwave signal output by the power amplifier circuit 120 at this time should not be too high (e.g., lower than the maximum input power of the microwave radiator). This is why the present application only adjusts the power amplification level of the power amplifier circuit 120 to the lowest level when the control and processor 142 determines the grab event and the hand-lift event before taking a puff. Preferably, in the present application, the maximum input power of the microwave radiator is set to 15 to 40W.

[0044] It can be understood that when preheating the aerosol generator before inhalation, the power amplification level of the power amplifier circuit 120 is only the lowest level, that is, the power of the first target microwave signal output by the power amplifier circuit 120 is relatively low. If the aerosol generator is heated with such a lower power target microwave signal, the time for the aerosol generator to be heated and atomized into aerosol is relatively long. Moreover, when the aerosol generator is heated with such a lower power target microwave signal, the user has already held the aerosol generating device and raised his hand before inhaling, which means that the user will perform an inhalation action in a shorter period of time. In view of this, in order to shorten the time for the aerosol generator to be heated and atomized into aerosol when the user inhales, the present application will subsequently increase the power amplification level of the power amplifier circuit 120 when the user inhales, that is, increase the power of the target microwave signal output by the power amplifier circuit 120, so that the aerosol generator can be quickly atomized into aerosol for the user to inhale when the user inhales, thereby ensuring the user's usage experience.

[0045] Specifically, for electronic atomization devices, the housing is typically provided with a mouthpiece that communicates with the interior of the housing. The user can hold the mouthpiece with their lips and inhale, thereby inhaling the aerosol generated by the heated aerosol generator. Based on this, lip contact data generated when the user's lips contact the outer surface of the mouthpiece can be used to determine whether the user is currently or about to perform a puffing action, thereby accurately identifying the timing for increasing the power amplification level of the power amplifier circuit 120. In view of this, during the actual microwave heating control process, the control and processor 142 can obtain lip contact data between the user's lips and the outer surface of the mouthpiece, and determine whether the user has puffed on the aerosol generating device based on the lip contact data. Once a puffing event is determined to have occurred, the control and processor 142 will output a second power amplification instruction, and the power amplifier circuit 120 can respond to the second power amplification instruction and adjust its own power amplification level from level 1 to level 2, thereby amplifying the initial microwave signal at the level 2 power amplification level to obtain a second target microwave signal. It is understandable that since the second target microwave signal is obtained at a second power amplification level, while the first target microwave signal is only obtained at a first power amplification level, the power of the second target microwave signal is greater than the power of the first target microwave signal. Therefore, after adjusting the power amplification level of the power amplifier circuit 120 from level one to level two, it can be ensured that the aerosol generator can quickly atomize aerosol for the user to inhale when the user inhales, that is, the user experience is guaranteed. Preferably, the power of the first target microwave signal is 1 / 2 of the maximum input power of the microwave radiator, and the power of the second target microwave signal is the maximum input power of the microwave radiator. In addition, it should be noted that the power amplification levels of the power amplifier circuit 120 are not limited to level one and level two, but can also include more and higher levels, such as level three and level four. As for how to design the power amplification level of the power amplifier circuit 120, it can be determined according to actual needs.

[0046] In some implementations of this embodiment, please refer to Figure 1. A third sensor cluster 170 is provided on the outer surface of the nozzle. The third sensor cluster 170 is composed of at least one third sensor. When the third sensor cluster 170 includes multiple third sensors, the multiple third sensors are distributed at different positions on the nozzle. Each third sensor in the third sensor cluster 170 is embedded inward from the outer surface of the nozzle. The purpose is to ensure the smoothness of the outer surface of the nozzle and avoid a scratchy feeling when the user holds the nozzle with his lips. The third sensor cluster 170 can rely on its own multiple third sensors to collect lip contact data in real time, and transmit the collected lip contact data to the control and processor 142 in the single-chip microcomputer 140. As one of the implementation methods, the third sensor uses a pressure sensor. When the user holds the mouthpiece with his lips, the pressure sensor will inevitably detect pressure, and the detected pressure should be greater than a certain value. That is to say, the lip contact data at least includes the pressure data between the user's lips and the outer surface of the mouthpiece, and the control and processor 142 in the single-chip microcomputer 140 can compare this pressure data with a preset pressure value. When this pressure data is greater than the preset pressure value, it can be considered that the user has held the mouthpiece with his lips and is about to inhale. At this time, the control and processor 142 will output a second power amplification instruction to the power amplifier circuit 120 to instruct the power amplifier circuit 120 to adjust its own power amplification level from level one to level two, thereby shortening the time for the aerosol generator to atomize out aerosol due to heat when the user inhales.

[0047] In some implementations of this embodiment, please refer to Figure 1. The power amplifier circuit 120 includes several power amplifiers, and the connection form between the several power amplifiers can be adjusted. The present application can change the power amplification level of the power amplifier circuit 120 by adjusting the connection form between the several power amplifiers, that is, change the power of the target microwave signal output by the power amplifier circuit 120. For example, the number of power amplifiers connected together in the power amplifier circuit 120 is adjusted to change the power amplification level of the power amplifier circuit 120. That is to say, when the number of power amplifiers in the power amplifier circuit 120 used to connect the microwave generating circuit 110 and the microwave output circuit 130 is different, the power amplification level of the power amplifier circuit 120 is also different.

[0048] As one implementation, still referring to FIG1 , the power amplifier circuit 120 includes a first power amplifier AM1, a second power amplifier AM2, a third power amplifier AM3, and a fourth power amplifier AM4. The input end of the first power amplifier AM1 is connected to the microwave generating circuit 110, and the output end is connected to the input end of the second power amplifier AM2. The input ends of the third power amplifier AM3 and the fourth power amplifier AM4 are connected in parallel and then connected to the output end of the second power amplifier AM2. The output ends of the third power amplifier AM3 and the fourth power amplifier AM4 are connected in parallel and then connected to the microwave output circuit 130. In the first power amplification level, the first power amplifier AM1, the second power amplifier AM2, and the third power amplifier AM3 are connected, that is, the power amplifier circuit 120 is used for The number of power amplifiers connecting the microwave generating circuit 110 and the microwave output circuit 130 is three, namely the first power amplifier AM1, the second power amplifier AM2 and the third power amplifier AM3, and the power amplifier circuit 120 outputs a first target microwave signal with lower power; under the second-level power amplification level, the first power amplifier AM1, the second power amplifier AM2, the third power amplifier AM3 and the fourth power amplifier AM4 are connected, that is, the number of power amplifiers in the power amplifier circuit 120 used to connect the microwave generating circuit 110 and the microwave output circuit 130 is four, namely the first power amplifier AM1, the second power amplifier AM2, the third power amplifier AM3 and the fourth power amplifier AM4, and the power amplifier circuit 120 outputs a second target microwave signal with higher power. Furthermore, Figure 6 is a power diagram of the target microwave signal under different heating control stages, wherein the second stage corresponds to the power of the first target microwave signal, the third stage corresponds to the power of the second target microwave signal, and the first stage corresponds to the situation where the user holds the aerosol generating device and raises his hand before inhalation occurs. At this time, the microwave generating circuit 110 does not generate an initial microwave signal, and the power amplifying circuit 120 does not output the target microwave signal. Therefore, the power of the target microwave signal in this stage is zero.

[0049] Normally, during the heating process of the aerosol generator, high-frequency electromagnetic leakage is likely to occur on the microwave radiator and / or the aerosol generator. If the human body is exposed to the electromagnetic environment for a long time, it will cause serious damage to the human body. In other words, it is very necessary to monitor the electromagnetic leakage on the microwave radiator and / or the aerosol generator. In view of this, in some embodiments, please refer to Figure 1, in addition to the structures listed above, the aerosol generating device also includes a power supply 180 for power supply and at least one electromagnetic monitoring antenna 190. The electromagnetic monitoring antenna 190 is arranged in the shell and is located near the microwave radiator and / or the aerosol generator. The power supply 180 can provide the various structures in the aerosol generating device (such as the microwave generating circuit 110, the power amplification circuit 120, the microwave output circuit 130 and the single-chip computer 140, etc.) with the required electrical energy for operation; in the actual microwave heating control process, the electromagnetic monitoring antenna 190 can absorb the electromagnetic signal leaked from the microwave radiator and / or the aerosol generator, and output the absorption power generated by the absorption of the electromagnetic signal to the control and processor 142, and the control and processor 142 can predict and estimate whether the leaked electromagnetic signal will cause damage to the user's body after being radiated to the outside based on the absorption power.

[0050] As one embodiment, FIG7 is a schematic diagram of a process for electromagnetic exposure monitoring. The process for the control and processor 142 to implement electromagnetic exposure monitoring based on absorbed power includes steps 701 and 702 (abbreviated as S701 and S702), namely: S701, determining whether there is an electromagnetic exposure risk based on the absorbed power; S702, if there is an electromagnetic exposure risk, outputting a power-off instruction to the power supply 180. It is understood that during the heating process of the aerosol generator, electromagnetic leakage occurs on the microwave radiator and / or the aerosol generator. The leaked electromagnetic signal can be absorbed by the electromagnetic monitoring antenna 190 and generate absorbed power accordingly. The control and processor 142 of the present application can determine whether there is an electromagnetic exposure risk based on the absorbed power, and when it is determined that there is an electromagnetic exposure risk, output a power-off instruction to the power supply 180 to instruct the power supply 180 to shut down, thereby preventing the user from being exposed to the electromagnetic environment for a long time and causing damage to the user's body.

[0051] In some implementations of this embodiment, FIG8 shows a flow diagram of S701 in FIG7 . The process for the control and processor 142 to determine whether there is an electromagnetic exposure risk based on the absorbed power includes steps 7011 to 7013 (abbreviated as S7011 to S7013), namely: S7011, predicting the power loss after the electromagnetic signal is radiated to the outside, and predicting the average electric field strength of the electromagnetic signal after it is radiated to the outside based on the absorbed power and the power loss; S7012, predicting the specific absorption rate of the electromagnetic signal relative to the human body after it is radiated to the outside based on the average electric field strength, and determining whether the specific absorption rate meets the corresponding safety standards; S7013, if the specific absorption rate does not meet the safety standards, determining that there is an electromagnetic exposure risk. As one implementation, the power loss prediction formula is L = 32.44 + 201g (d) + 201g (f), where L is the power loss, d is the distance the electromagnetic signal is radiated to the outside, and f is the frequency of the electromagnetic signal. As one implementation, the specific absorption rate prediction formula is SAR = (σ|E2|) / ρ, where σ is the human body conductivity (generally, the range of human body conductivity is 0.5 to 2 S / m), ρ is the human tissue density, E is the average electric field strength, and SAR is the specific absorption rate. It should be noted that in the related art, there are two safety standards for specific absorption rate: one is the US standard (i.e., 1g of biological tissue does not exceed 1.6 W / kg), and the other is the European standard (i.e., 10g of biological tissue does not exceed 2 W / kg). However, this application does not adopt either of these standards. Instead, the safety standard for specific absorption rate is set to less than or equal to 1.2 to 1.4 W / kg. In other words, when the control and processor 142 determines that the predicted specific absorption rate exceeds 1.2 to 1.4 W / kg, the power supply 180 can be controlled to shut down. It should also be noted that the control and processor 142 can be connected to external smart terminals such as mobile phones, smart wearable devices, tablets and laptops through wired or wireless means, and send various data detected or predicted during the electromagnetic monitoring process (such as absorption power, power loss, average electric field strength and specific absorption rate, etc.) to the smart terminal, and the smart terminal can visually display the data it receives to the user, so that the user can more intuitively understand the electromagnetic leakage of the aerosol generating device.

[0052] It is understood that in the process of the control and processor 142 determining whether there is an electromagnetic exposure risk based on absorbed power, the data involved, such as power loss, average electric field strength, and specific absorption rate, are all predicted and estimated, rather than accurately calculated data. In other words, the control and processor 142 can estimate the electromagnetic leakage of the aerosol generating device through certain predictive estimation models, such as the Kalman filter model and its variations, or machine learning models, to predict these data. Furthermore, FIG9 is a diagram estimating the power of the leaked electromagnetic signal radiated to the outside. Assuming there are four electromagnetic monitoring antennas 190, during a heating process of the aerosol generator, the true trajectory represents the actual power of the electromagnetic signal leaked from the microwave radiator and / or the aerosol generator at each electromagnetic monitoring antenna 190. The observed sample represents the absorbed power output by the port of each electromagnetic monitoring antenna 190 due to the absorption of the corresponding electromagnetic signal. The estimated trajectory represents the power of the leaked electromagnetic signal radiated to the outside, as predicted and estimated after Kalman filtering of the observed sample (i.e., the absorbed power). In addition, it should be noted that the control and processor 142 of the present application can not only predict and estimate the electromagnetic leakage of the aerosol generating device, but also predict and estimate the electromagnetic compatibility of the aerosol generating device, that is, the control and processor 142 can also predict and estimate the degree of interference of the leaked electromagnetic signal on each structure in the aerosol generating device based on the absorbed power, and use this to evaluate the working condition of the aerosol generating device. Even when any structure in the aerosol generating device cannot work stably due to interference from the leaked electromagnetic signal, the power supply 180 can be directly controlled to be turned off, thereby avoiding damage to the various structures in the aerosol generating device due to electromagnetic interference.

[0053] Under normal circumstances, the microwave generating circuit 110 will generate a low-power microwave signal (with a power of 5 to 10 dBm) at the same time as generating the initial microwave signal. At this time, the human body (i.e., the user) is used as an antenna, and the low-power microwave signal will be absorbed by the human body, and the human body can be equivalent to a near-field parallel load, that is, the human body will perform frequency deviation processing on the absorbed low-power microwave signal to obtain a frequency-deviation microwave signal. The obtained frequency-deviation microwave signal is sequentially transmitted through the user's palm and the first sensor cluster 150 (the first sensor of which needs to be a microwave sensor) to the control and processor 142. The control and processor 142 can mix the palm contact data, elbow movement data, and frequency-deviation microwave signal received by itself to obtain a mixed signal, and transmit the mixed signal to an external smart terminal via wired or wireless means. The external smart terminal can analyze and process the mixed signal received by itself, thereby achieving the effect of classifying and judging the user's use of the aerosol generating device. Furthermore, the loop of the low-power microwave signal is equivalent to the LC1 oscillation circuit, and the human body (i.e., the user) is used as the equivalent capacitor C2 in parallel to obtain different resonant frequencies. Then, the amplitude (-10 to -30 dB) and phase information (-180° to 180°) at different resonant frequencies are input as characteristic parameters into the control and processor 142, so as to serve as the basis for the control and processor 142 to output the mixing information. Among them, the change of the frequency of the low-power microwave signal when it is transmitted in the loop satisfies the formula and fr represents the frequency of the low-power microwave signal, and L represents the inductance of the loop.

[0054] The above embodiments are only preferred implementations of the present application and are not the only limitations on the relevant contents of the microwave control method. In this regard, those skilled in the art can flexibly set them according to actual application scenarios based on the above embodiments. It can be understood that through the implementation of the above embodiments of the present application, the single-chip microcomputer 140 can obtain the palm contact data between the user's palm and the outer surface of the shell of the aerosol generating device, and the elbow movement data of the user's elbow during the movement process, and judge whether the user has grasped the aerosol generating device before inhalation based on the palm contact data, and judge whether the user has raised his hand to hold the aerosol generating device before inhalation based on the elbow movement data. Once the grasping event and the hand-raising event before inhalation are determined to have occurred, the single-chip microcomputer 140 will send a microwave generation instruction to the microwave generating circuit 110 to instruct the microwave generating circuit 110 to generate an initial microwave signal, and send a power amplification instruction to the power amplifier circuit 120 to instruct the power amplifier circuit 120 to enter a conduction state allowing signal transmission and amplify the power of the initial microwave signal to obtain a target microwave signal. Finally, the microwave output circuit 130 outputs the target microwave signal to the microwave radiator, so that the microwave radiator radiates the target microwave signal to the aerosol generator to pre-heat the aerosol generator before inhalation. That is to say, when the present application determines based on the palm contact data and elbow movement data that the user has grasped the aerosol generating device and raised his hand, it can be assumed that the user will take a puff in a short period of time thereafter. Then, before the user takes a puff (that is, in the process of the user holding the aerosol generating device and raising his hand), the present application will control the microwave generating circuit 110 to generate an initial microwave signal, and control the power amplifier circuit 120 to enter a conductive state allowing signal transmission, so as to use the power amplifier circuit 120 to amplify the power of the transmitted initial microwave signal and obtain the target microwave signal accordingly. The obtained target microwave signal will be output to the microwave radiator by the power amplifier circuit 120, thereby realizing preheating of the aerosol generator before the user takes a puff. In this way, the instantaneous heating phenomenon of the aerosol generator when the user takes a puff is avoided in the traditional scheme (that is, the temperature of the aerosol generator is instantaneously increased to be able to atomize the aerosol, or the electric power used to heat the aerosol generator is instantaneously increased to be able to atomize the aerosol), thereby improving the service life of the electronic atomization device.
