Abstract
Description
Technical Field
[0001] The present application relates to the technical field of microwave heating, in particular to a control method, system, device and medium for a microwave heating aerosol generating device. Background Art
[0002] A microwave heating aerosol generating device is a device that uses microwave heating technology to convert sol substances in a liquid into aerosol. It generally consists of a microwave generating system, a microwave control system, a nebulizer, a heating chamber, etc. In a microwave heating aerosol generating device, a microwave signal is generated by the microwave generating system and transmitted to the heating chamber through the microwave control system. The nebulizer in the heating chamber atomizes the sol substances in the liquid into tiny particles, and then through the action of microwave heating, the particles are rapidly heated up to form aerosol. An electronic cigarette device is a common microwave heating aerosol generating device, which is favored by users because of its light weight, easy to carry and convenient to use.

The described embodiments should not be regarded as limitations on the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.
[0054] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with each other without conflict.
[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.
[0056] A microwave heating aerosol generating device is a device that uses microwave heating technology to convert sol substances in a liquid into aerosol. It generally consists of a microwave generating system, a microwave control system, a nebulizer, a heating chamber, etc. In a microwave heating aerosol generating device, a microwave signal is generated by the microwave generating system and transmitted to the heating chamber through the microwave control system. The nebulizer in the heating chamber atomizes the sol substances in the liquid into tiny particles, and then through the action of microwave heating, the particles are rapidly heated to form aerosol. An electronic cigarette device is a common microwave heating aerosol generating device and is popular among users because of its light weight, easy portability and convenient use.
[0057] In the related art, in order to improve the efficiency of heating and producing aerosol in a microwave heating aerosol generating device such as an electronic cigarette device, electromagnetic waves in a high-power microwave band are generally fed into a heating chamber in a short time, so as to improve the heating and temperature rising speed as much as possible. However, in practical applications, it is found that electromagnetic waves in a high-power microwave band are likely to cause electromagnetic exposure damage to the human body, and local overheating may occur in the impedance mutation part of the microwave source or the microwave radiator, and the overall safety of the device is poor.
[0058] In view of this, in an embodiment of the present application, a control method for a microwave heating aerosol generating device is provided. Based on multi-modal sensor signals, this method can capture the posture and actions of the user to achieve early microwave heating control, which is beneficial to reducing the power of microwave heating and improving the safety and reliability of microwave heating while improving the heating and temperature rising speed as much as possible.
[0059] Before introducing the control method for the microwave heating aerosol generating device provided in the present application, first introduce the microwave heating aerosol generating device involved in the embodiment of the present application. Please refer to Figure 1 , Figure 1 FIG. shows a schematic structural diagram of a microwave aerosol generating device provided in an embodiment of the present application. Generally speaking, a microwave aerosol generating device may include a power supply, a microwave source, a microwave radiator, and a medium to be heated. Among them, the power supply is used to provide electrical energy for the entire device to work normally; the microwave source can be used to generate microwave signals and perform a certain power amplification process on the microwave signals for heating the medium; the microwave radiator can be used to radiate the microwave signals to the medium to be heated in a specific manner to achieve a heating effect; the medium to be heated is used to receive the microwave signals and convert them into heat energy, so as to be heated to form aerosol.
[0060] Refer to Figure 1 , in the microwave source, it generally includes a microwave generating system and a microwave control system. Among them, the microwave generating system is responsible for generating microwave signals, which usually consists of devices such as an oscillator, and generates high-frequency microwave signals through stable electromagnetic wave oscillation. The microwave control system can be used to control parameters such as the power, frequency, and working mode of the microwave signals, and usually consists of a processor, a power amplifier, a frequency regulator, etc. Through the microwave control system, precise control and adjustment of the microwave signals can be achieved. The method in the embodiment of the present application can be applied in the microwave control system.
[0061] Of course, it can be understood that, Figure 1The microwave aerosol generating device shown is only used to exemplify a common structural mode, and does not mean that the present application is limited to the specific structure and components of the microwave aerosol generating device. The control method of the microwave heating aerosol generating device provided in the embodiment of the present application can be applied to any (or multiple) components of the microwave heating aerosol generating device, and the present application is not limited to this.
[0062] For example, in the embodiments of the present application, the control method is introduced and described by taking the execution of the microwave control system as an example.
[0063] Reference Figure 2 , Figure 2 1 is a flow chart of a control method of a microwave heating aerosol generating device provided in an embodiment of the present application. The control method of the microwave heating aerosol generating device includes but is not limited to:
[0064] Step 210, detecting the state of the human palm covering the microwave aerosol generating device to obtain a first detection signal;
[0065] In this step, when the microwave heating aerosol generating device is controlled, the state of the human palm covering the microwave aerosol generating device can be detected to obtain a corresponding sensor signal, which is recorded as a first detection signal in the embodiment of the present application. In the embodiment of the present application, the specific type of the first detection signal is not limited.
[0066] Reference Figure 3 , Figure 3 A schematic diagram of the structure of a microwave control system for realizing a control method of a microwave-heated aerosol generating device provided in an embodiment of the present application is shown. In the microwave control system provided in an embodiment of the present application, it mainly includes a first detection module, a second detection module, a processor module and a power amplifier module. Among them, the first detection module and the second detection module are used to capture the posture and movement of the user, and transmit the relevant signals to the processor module, and the processor module can control the power amplifier module according to the detected signals. In this way, the microwave signal can be output in advance before the user actually starts to use the microwave aerosol generating device, and the microwave heating control can be realized in advance, which can help reduce the power of microwave heating, and improve the safety and reliability of microwave heating while maximizing the heating temperature rise rate.
[0067] Specifically, in the embodiments of the present application, the first detection module can be used to detect the first detection signal generated by the microwave aerosol generating device covered by the human palm. Here, the first detection signal can include one or more signals. Exemplarily, for example, in the first detection module, there can be at least one of a pressure sensor or a temperature sensor. Taking the case where only a pressure sensor is included in the first detection module as an example, the pressure sensor can be used to detect whether the user is holding the microwave aerosol generating device. For example, a threshold value of pressure (or pressure within a certain area) can be set, and the pressure data detected by the pressure sensor is compared with this threshold value. If it is greater than the threshold value, it can be considered that the user is holding the microwave aerosol generating device. Taking the case where only a temperature sensor is included in the first detection module as an example, the temperature sensor can be used to detect whether the user is holding the microwave aerosol generating device. Similarly, a temperature threshold value (such as the surface temperature of the human palm) can be set, and then it is determined whether the temperature data detected by the temperature sensor reaches this temperature threshold value, so as to determine whether the user is holding the microwave aerosol generating device. Of course, in the embodiments of the present application, the first detection module can also include both a pressure sensor and a temperature sensor at the same time. At this time, it can be determined whether the user is holding the microwave aerosol generating device according to the detection situations of both the pressure sensor and the temperature sensor. For example, when both meet the threshold conditions, it is considered that the user is holding the microwave aerosol generating device.
[0068] Step 220: Detect the action of the human body holding the microwave aerosol generating device to obtain a second detection signal;
[0069] In this step, the action of the human body holding the microwave aerosol generating device is also detected, and the obtained sensing signal is recorded as the second detection signal. Refer to Figure 3 , where the second detection signal can be detected by the second detection module. Similarly, in the embodiments of the present application, the second detection signal can also include one or more signals. Exemplarily, for example, in the second detection module, there can be at least one of an accelerometer or a gyroscope. Among them, the accelerometer can detect the acceleration change of an object in a three-dimensional coordinate system, that is, the acceleration vector of the object in space. In the microwave aerosol generating device, the accelerometer can detect the motion state of the device. The gyroscope can measure the rotational speed of an object around the rotation axis, that is, the angular velocity of the object. In the microwave aerosol generating device, the gyroscope can detect the motion states such as the rotation, turning, and tilting of the device. It can be understood that in the embodiments of the present application, the data detected by the second detection module can be used to analyze the posture, direction, and angle changes of the device, so as to determine whether the user is holding the microwave aerosol generating device and moving, and further obtain the conclusion of whether the microwave aerosol generating device is about to be used.
[0070] Step 230: Determine whether the microwave aerosol generating device is to be used according to the first detection signal and the second detection signal;
[0071] In this step, after obtaining the first detection signal and the second detection signal, it can be determined whether the microwave aerosol generating device is to be used based on these two signals.
[0072] Specifically, it can be understood that according to the first detection signal, it can be determined whether the microwave aerosol generating device is held by the user. If it is found that the microwave aerosol generating device is not held by the user, it can be considered that the user has no intention of using the microwave aerosol generating device, and thus there is no need to perform pre - microwave heating on it. On the contrary, if it is found that the microwave aerosol generating device is held by the user, it can be considered that the user may have the intention of using the microwave aerosol generating device. At this time, according to the second detection signal, it can be further determined whether the user holds and moves the microwave aerosol generating device. If it is found that the microwave aerosol generating device is not held and moved by the user, it can be considered that the user is just holding the microwave aerosol generating device at this time, without any action and without the intention of using the microwave aerosol generating device. If it is found that the microwave aerosol generating device is held and moved by the user, it can be considered that the user is very likely to use the microwave aerosol generating device, that is, it can be determined that the microwave aerosol generating device is to be used.
[0073] Step 240: If it is determined that the microwave aerosol generating device is to be used, control the microwave aerosol generating device to perform microwave heating at a first power output.
[0074] In this step, if it is determined that the microwave aerosol generating device is to be used, the microwave aerosol generating device can be controlled to perform microwave heating. Here, the heating power of the microwave aerosol generating device is denoted as the first power. In the embodiments of the present application, the specific magnitude of the first power is not limited, and it can be any value less than or equal to the maximum safe heating power.
[0075] Refer to Figure 3In an embodiment of the present application, the first detection module and the second detection module are connected to the output end of the processor module, and can transmit relevant detection signals to the processor module. Here, it should be noted that what the first detection module and the second detection module transmit to the processor module can be some processed determination signals or original sensor signals, and the present application does not limit this. Exemplarily, taking the example of the first detection module and the second detection module transmitting sensor signals to the processor module, the processor module can determine whether the user is going to use the microwave aerosol generating device based on the transmitted sensor signals. Specifically, if the sensor signals transmitted by the first detection module and the second detection module both meet the set conditions, it can be determined that the user is going to use the microwave aerosol generating device. At this time, the processor module can control the power amplifier module to amplify the microwave signal, thereby realizing pre-microwave heating.
[0076] In an embodiment of the present application, the input end of the power amplifier module is used to connect to the microwave generation front circuit, for receiving the weak signal from the microwave generation front circuit, and amplifying it to a sufficient power level. This ensures that the microwave signal can be effectively transmitted to the microwave source output circuit. The output end of the power amplifier module is connected to the microwave source output circuit, and the amplified microwave signal is transmitted to ensure that the microwave source can output sufficiently powerful microwave energy for heating the medium. In an embodiment of the present application, the output end of the processor module is connected to the power amplifier module, which is used to control the working state of the power amplifier module. The processor module can adjust the working parameters of the power amplifier module, such as the power level, etc., as needed to achieve precise control of the microwave signal. Specifically, in an embodiment of the present application, the processor module can pre-start the power amplifier module according to the signals of the first detection module and the second detection module, and perform heating operations before the user starts using the microwave aerosol generating device.
[0077] It can be understood that the control method of a microwave aerosol generating device provided in the embodiment of the present application detects the state of the human palm covering the microwave aerosol generating device to obtain a first detection signal; detects the action of the human body holding the microwave aerosol generating device to obtain a second detection signal; determines whether the microwave aerosol generating device will be used according to the first detection signal and the second detection signal; if it is determined that the microwave aerosol generating device will be used, controls the microwave aerosol generating device to perform microwave heating with a first power output. The method is based on multi-modal sensor signals, and realizes advance microwave heating control by capturing the user's posture and action, which can help reduce the power of microwave heating, and improve the safety and reliability of microwave heating while maximizing the heating temperature rise rate.
[0078] Specifically, in some embodiments, detecting the state of the microwave aerosol generating device covered by a human palm to obtain a first detection signal includes:
[0079] Detecting the holding pressure of the microwave aerosol generating device to obtain a pressure sensing signal;
[0080] Detecting the surface temperature of the microwave aerosol generating device to obtain a temperature sensing signal;
[0081] Obtaining a first detection signal according to the pressure sensing signal and the temperature sensing signal.
[0082] The first detection signal in the embodiments of the present application may include one or more signals. Refer to Figure 4 , Figure 4 FIG. shows a schematic structural principle diagram of a microwave control system provided in the embodiments of the present application. In some embodiments, when detecting the state of the microwave aerosol generating device covered by a human palm, the holding pressure of the microwave aerosol generating device can be detected to obtain a pressure sensing signal, and the surface temperature of the microwave aerosol generating device can be detected to obtain a temperature sensing signal. Then, a first detection signal can be obtained according to the pressure sensing signal and the temperature sensing signal. Specifically, in the embodiments of the present application, the signals detected by the pressure sensor and the temperature sensor can be transmitted to the first feedback module, and the first detection signal can be obtained by fusing these signals through the first feedback module.
[0083] Specifically, in some embodiments, detecting the action of a human holding the microwave aerosol generating device to obtain a second detection signal includes:
[0084] Determining whether the microwave aerosol generating device is held according to the first detection signal;
[0085] If it is determined that the microwave aerosol generating device is held, detecting the action of a human holding the microwave aerosol generating device to obtain a second detection signal.
[0086] In the embodiments of the present application, when detecting the action of a human holding the microwave aerosol generating device, it can first be determined whether the microwave aerosol generating device is held according to the detected first detection signal. It can be understood that if the microwave aerosol generating device is not held, it means that it is not in a situation where it is about to be used, and there is no need to detect the action of a human holding the microwave aerosol generating device anymore. On the contrary, when it is determined according to the first detection signal that the microwave aerosol generating device is held, the action of a human holding the microwave aerosol generating device can be detected to obtain a second detection signal. In this way, the detection and processing of the second detection signal can be carried out in a timely manner, improving the efficiency of detection.
[0087] Specifically, in some embodiments, detecting the action of a human holding the microwave aerosol generating device to obtain a second detection signal includes:
[0088] Detecting the acceleration of the movement of the microwave aerosol generating device to obtain an acceleration sensing signal;
[0089] Detecting the pitch angle of the movement of the microwave aerosol generating device to obtain a pitch angle sensing signal;
[0090] Fusing the acceleration sensing signal and the pitch angle sensing signal to obtain a second detection signal.
[0091] The second detection signal in the embodiments of the present application may also include one or more signals. Refer to Figure 4 , in some embodiments, when detecting the action of a human holding the microwave aerosol generating device, the acceleration of the movement of the microwave aerosol generating device can be detected to obtain an acceleration sensing signal, and the pitch angle of the movement of the microwave aerosol generating device can be detected to obtain a pitch angle sensing signal. Then, a second detection signal can be obtained according to the acceleration sensing signal and the pitch angle sensing signal. Specifically, in the embodiments of the present application, the acceleration sensing signal and the pitch angle sensing signal can be transmitted to a second feedback module, and the second feedback module can fuse these signals to obtain a second detection signal. In some embodiments, the secondary feedback module can also add or replace a microwave sensing system based on the Doppler effect to improve the accuracy of action capture and pose recognition.
[0092] Specifically, in some embodiments, determining whether the microwave aerosol generating device will be used according to the first detection signal and the second detection signal includes:
[0093] When the pressure sensing signal is greater than a first threshold, the temperature sensing signal is greater than a second threshold, the acceleration sensing signal is greater than a third threshold and less than a fourth threshold, and the pitch angle sensing signal is greater than a fifth threshold, it is determined that the microwave aerosol generating device will be used.
[0094] In the embodiments of the present application, refer to Figure 4, taking the first detection module including a pressure sensor and a temperature sensor as an example, the output ends of the pressure sensor and the temperature sensor can be connected to the input end of the first feedback module, and the output end of the first feedback module can be connected to the processor module. Here, the first feedback module can perform relevant determination operations through a built-in comparator. Exemplarily, for example, when the outer surface area of the microwave aerosol generating device covered by the user's palm exceeds 70%, and the local pressure of the covered part of the palm exceeds 0.02 Pa, and at the same time the temperature sensor reaches the palm body surface temperature in the hand-held area for 0 to 1 second, the first-level feedback module generates a signal determining that the user is holding the microwave aerosol generating device, and this signal can be a high-level signal. In contrast, if the detection signals output by the pressure sensor and the temperature sensor do not meet the predetermined conditions, the first-level feedback module can output a low-level signal to the processor module. Here, 0.02 Pa is equivalent to the set first threshold, and the palm body surface temperature is equivalent to the set second threshold. The specific magnitudes of these thresholds are not limited in this application.
[0095] Similarly, within the second detection module, the function of the second feedback module is similar to that of the first feedback module and can be used to process the detection signals of the accelerometer or the gyroscope. The accelerometer and the gyroscope can be connected to the input end of the second feedback module, and the output end of the second feedback module can be connected to the processor module for outputting relevant determination signals. Exemplarily, for example, within 0 to 5 seconds, the acceleration generated by the accelerometer reaches between 0.9 and 2 m / s², and the pitch angle generated by the gyroscope exceeds a 90-degree offset. The second-level feedback module generates a signal determining that the user is about to use the microwave aerosol generating device, and this signal can be a high-level signal. In contrast, if the detection signals output by the accelerometer and the gyroscope do not meet the predetermined conditions, the second-level feedback module can output a low-level signal to the processor module. Here, 0.9 m / s² is equivalent to the set third threshold, 2 m / s² is equivalent to the set fourth threshold, and 90 degrees is equivalent to the set fifth threshold. The specific magnitudes of these thresholds are also not limited in this application.
[0096] In the embodiment of this application, when both the first detection module and the second detection module output high-level signals, the processor module can determine that the microwave aerosol generating device will be used. Of course, it can be understood that the above method of determining whether the microwave aerosol generating device will be used based on the first detection signal and the second detection signal is only for exemplary illustration and does not mean that this application limits its specific implementation logic. In some embodiments, Kalman filtering, multi-Bayesian estimation, artificial neural networks, etc. can be selected within the first feedback module, the second feedback module, and the processor module to process the signals to obtain the corresponding determination signal results.
[0097] Specifically, in some embodiments, the microwave aerosol generating device includes a pre - microwave - generating circuit for outputting an original microwave signal; obtaining a first detection signal according to the pressure sensing signal and the temperature sensing signal includes:
[0098] Detecting the microwave frequency deviation signal of the original microwave signal;
[0099] Fusing the pressure sensing signal, the temperature sensing signal and the microwave frequency deviation signal to obtain a first detection signal.
[0100] In the embodiments of the present application, the state detection of the human palm covering the microwave aerosol generating device can also be realized based on the microwave frequency deviation signal. Specifically, please refer to Figure 5 , Figure 5 which shows the schematic structural principle diagram of another microwave control system provided in the embodiments of the present application. The microwave control system in the embodiments of the present application further includes a microwave sensor unit. The input end of the microwave sensor unit can be connected to the pre - microwave - generating circuit, and the pre - microwave - generating circuit can input a low - power microwave signal to the microwave sensor unit, which is denoted as the original microwave signal in the embodiments of the present application. When the user's palm covers the microwave aerosol generating device, the human body can be equivalent to a near - field parallel load, and different contact objects will cause different frequency deviation signals in the microwave sensor unit. Specifically, the original low - power microwave signal loop can be equivalent to an LC1 oscillation circuit, where C1 is the overall capacitance of the circuit. At this time, the resonant frequency of the circuit can be expressed as:
[0101]
[0102] When the user's palm covers the microwave aerosol generating device, taking the human body as a parallel equivalent capacitance C2, the resonant frequency of the circuit can be expressed as:
[0103]
[0104] It can be seen that when the user's palm covers the microwave aerosol generating device, the resonant frequency of the circuit will change. Therefore, it is possible to detect whether the user is holding the microwave aerosol generating device based on this principle through the microwave sensor unit, and transmit the detected signal to the processor module. In the embodiments of the present application, the pressure sensing signal, the temperature sensing signal and the microwave frequency deviation signal can be integrated to obtain a first detection signal, thereby improving the detection accuracy.
[0105] Specifically, in some embodiments, the method further includes:
[0106] When it is determined that the microwave aerosol generating device is in use, controlling the microwave aerosol generating device to perform microwave heating with a second power output;
[0107] Wherein, the second power is greater than or equal to the first power.
[0108] In the embodiments of the present application, for the power amplifier module, it may include multiple power amplifier components. For example, please refer to Figure 4 , in some embodiments, the power amplifier module may include a first power amplifier 1, a second power amplifier 2, a third power amplifier 3, and a fourth power amplifier 4. Wherein, the input end of the first power amplifier 1 is used to connect the microwave generation pre-circuit, and the output end is connected to the input end of the second power amplifier 2. The output end of the second power amplifier 2 is connected to the input ends of the third power amplifier 3 and the fourth power amplifier 4. The output ends of the third power amplifier 3 and the fourth power amplifier 4 are used to connect the microwave source output circuit. The operating states of these power amplifiers can be controlled by the processor module. Exemplarily, the processor module can achieve its operation by controlling the conduction of the relevant switching tubes in the power amplifier. For example, the processor module can control the first power amplifier to conduct or turn off, so that the first power amplifier performs amplification operation or stops operation.
[0109] In the embodiments of the present application, by setting multiple power amplifier components in the power amplifier module, stepped power output can be achieved. Exemplarily, please refer to Figure 6 , Figure 6 shows a schematic diagram of the power output of a power amplifier module provided in the embodiments of the present application. In the embodiments of the present application, when the sensor signals of the first detection module and the second detection module meet the conditions for the user to use the microwave heating aerosol generating device, the processor module can control the first power amplifier 1 and the second power amplifier 2 to conduct, the second power amplifier 2 to the third power amplifier 3 and the fourth power amplifier 4 to conduct, or the second power amplifier 2 to the third power amplifier 3 (or the fourth power amplifier 4) to conduct alone to achieve a preheating effect, that is, the microwave source to the microwave radiator conducts. At this time, the microwave aerosol generating device performs microwave heating with the output of the first power.
[0110] More preferably, when the user is about to use the microwave heating aerosol generating device, the second power amplifier 2 can be controlled to be separately turned on between the third power amplifier 3 (or the fourth power amplifier 4). In this way, the power input to the microwave radiator can be about half of the maximum power. When the user starts to use the microwave heating aerosol generating device (i.e., the microwave aerosol generating device is being used), the second power amplifier 2 is controlled to be fully turned on between the third power amplifier 3 and the fourth power amplifier 4. At this time, the power input to the microwave radiator is the maximum power. In this way, the power output can be reduced during the preheating process and increased during the actual use process, better meeting the actual needs of the user. In other words, when it is determined that the microwave aerosol generating device will be used, microwave heating is performed with the output of the first power. When it is determined that the microwave aerosol generating device is being used, microwave heating is performed with the output of the second power, and the second power can be greater than or equal to the first power. In the embodiments of the present application, the specific values of the first power and the second power are not limited.
