Description

Technical Field

[0001] The present application relates to the technical field of electronic atomization equipment, and in particular to an electromagnetic leakage monitoring system of an aerosol generating device and an electronic atomization equipment. Background Art

[0002] The core components of electronic atomization equipment include MCU (Micro Control Unit, single chip microcomputer), power supply, aerosol generator and heating element mounted on the aerosol generator. MCU can use the power supply to transmit electrical energy to the heating element to make the heating element heat up, and the heat emitted by the heating element can heat the aerosol generator and generate aerosol accordingly. The generated aerosol is used for users to inhale. 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 fast speed. However, 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 the aerosol, or in other words, can instantly increase the electrical power of the heated aerosol generator to a level that can atomize 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 electromagnetic exposure, electromagnetic compatibility, partial overheating of the impedance mutation of the microwave source or microwave radiator, and other defects, among which electromagnetic exposure is the most serious, and long-term exposure to the electromagnetic environment will cause indelible damage to the user's body. 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 electrical power of the heated aerosol generator to reach the level that can atomize 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. Therefore, it is necessary to avoid electromagnetic leakage when microwaves heat the aerosol generator. Utility Model Content

[0004] In order to solve the above-mentioned technical problems existing in the related art, the first aspect of the embodiment of the present application provides an electromagnetic leakage monitoring system for an aerosol generating device, wherein the aerosol generating device includes a shell and a microwave radiator and an aerosol generator arranged in the shell, the aerosol generator is placed in the microwave radiator, and the microwave radiator is used to heat the aerosol generator by microwave radiation; the electromagnetic leakage monitoring system is arranged in the shell, and the electromagnetic leakage monitoring system includes a power supply for power supply, an electromagnetic monitoring unit and at least one electromagnetic monitoring antenna, and at least one electromagnetic monitoring antenna is arranged near the microwave radiator and / or the aerosol generator. Specifically, the electromagnetic monitoring antenna is used to 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; the electromagnetic monitoring unit is used to determine whether there is an electromagnetic exposure risk based on the absorption power, and when it is determined that there is an electromagnetic exposure risk, send a power-off instruction to the power supply to instruct the power supply to shut down.

[0005] The second aspect of the embodiment of the present application provides an electronic atomization device, which includes an aerosol generating device and the electromagnetic leakage monitoring system mentioned in the first aspect of the embodiment of the present application. The aerosol generating device includes a shell and a microwave radiator and an aerosol generator arranged in the shell. The aerosol generator is placed in the microwave radiator. The microwave radiator is used to heat the aerosol generator by microwave radiation. The electromagnetic leakage monitoring system is arranged in the shell.

[0006] It can be understood that through the implementation of the above technical solutions of the present application, in the process of heating the aerosol generator, there is electromagnetic leakage on the microwave radiator and / or the aerosol generator, and the leaked electromagnetic signal can be absorbed by the electromagnetic monitoring antenna and generate absorption power accordingly. The electromagnetic monitoring unit can determine whether there is an electromagnetic exposure risk based on the absorption power, and send a power-off command to the power supply to instruct the power to shut down when it is determined that there is an electromagnetic exposure risk. In other words, the present application can perform real-time electromagnetic leakage monitoring, thereby preventing users from being exposed to the electromagnetic environment for a long time and causing damage to the user's body.

[0011] 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 belong to the scope of protection of the present 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.

[0012] In the related art, 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 out an aerosol, or in other words, can instantly increase the electrical power of heating the aerosol generator to a level that can atomize out an 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 partial overheating of the impedance mutation part of the microwave source or microwave radiator. Among them, electromagnetic exposure is the most serious, and long-term exposure to an electromagnetic environment will cause indelible damage to the user's body; further, 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 electrical power of the heating aerosol generator to reach a level that can atomize out an aerosol. Although this time extension method can improve the above defects, it cannot guarantee the original stop-and-pump function of the electronic atomization device. To this end, the present application proposes an electromagnetic leakage monitoring system for an aerosol generating device in the following embodiments, which is used to monitor in real time whether there is a hidden danger of electromagnetic exposure to the user during the inhalation process, and when the hidden danger of electromagnetic exposure is detected, timely take corresponding safety actions (such as cutting off the power supply), thereby ensuring the user's life safety.

[0013] It should be noted that the electromagnetic leakage monitoring system can be applied in electronic atomization equipment. When the electromagnetic leakage monitoring system is configured in the electronic atomization equipment, the electromagnetic leakage monitoring system can perform real-time electromagnetic leakage monitoring. At the same time, the electronic atomization equipment also has all the advantages of the electromagnetic leakage monitoring system. Specifically, 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 heat the aerosol generator by microwave radiation, that is, 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, aerosol will be atomized, and the aerosol 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 the microwave radiator or outside the microwave radiator, as long as the microwave radiator can radiate the microwave signals 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 and the electromagnetic leakage monitoring system are both core components of the electronic atomization device. Normally, the shell of the aerosol generating device also serves as the outer shell of the electronic atomization device.

[0014] Figure 1It is a structural block diagram of an aerosol generating device. In some embodiments, the electromagnetic leakage monitoring system includes a power supply 160, a single-chip microcomputer 140 and at least one electromagnetic monitoring antenna 150. The electromagnetic monitoring antenna 150 is arranged in the shell and is located near the microwave radiator and / or the aerosol generator. The power supply 160 can provide the various structures in the aerosol generating device (such as the single-chip microcomputer 140 and the microwave generating circuit 110, the power amplification circuit 120, the microwave output circuit 130, etc. mentioned below) with the required electrical energy for operation. The single-chip microcomputer 140 plays a role in data processing and control in this application. The single-chip microcomputer 140 is provided with an electromagnetic monitoring unit 141. Various data involved in the electromagnetic leakage monitoring process are processed in the electromagnetic monitoring unit 141. Specifically, in the actual electromagnetic leakage monitoring process, the electromagnetic monitoring antenna 150 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, and the electromagnetic monitoring unit 141 can determine whether there is an electromagnetic exposure risk based on the absorption power, and send a power-off instruction to the power supply 160 when it is determined that there is an electromagnetic exposure risk, so as to instruct the power supply 160 to shut down. It can be understood that in the process of the aerosol generator being heated up, there is electromagnetic leakage on the microwave radiator and / or the aerosol generator, and the leaked electromagnetic signal can be absorbed by the electromagnetic monitoring antenna 150 and generate absorption power accordingly, and the present application can determine whether there is an electromagnetic exposure risk based on the absorption power, and control the power supply 160 to shut down when it is determined that there is an electromagnetic exposure risk, that is, the present application can perform real-time electromagnetic leakage monitoring, thereby preventing the user from being exposed to the electromagnetic environment for a long time and causing damage to the user's body.

[0015] As one of the embodiments, the specific process of the electromagnetic monitoring unit 141 judging whether there is an electromagnetic exposure risk based on the absorbed power is: predicting the specific absorption rate of the electromagnetic signal relative to the human body after being radiated to the outside based on the absorbed power; judging whether the specific absorption rate meets the corresponding safety standards, and determining that there is an electromagnetic exposure risk when it does not meet the safety standards. It should be noted that there are two safety standards for specific absorption rate in the related art, one of which is the American standard (i.e., 1g of biological tissue does not exceed 1.6W / 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 any of these two standards, but sets the safety standard for specific absorption rate to be less than or equal to 1.2~1.4W / kg. That is, when the electromagnetic monitoring unit 141 determines that the predicted specific absorption rate exceeds 1.2~1.4W / kg, the power supply 160 can be controlled to be turned off. In some implementations of this embodiment, the specific process of the electromagnetic monitoring unit 141 predicting the specific absorption rate of the electromagnetic signal relative to the human body after being radiated to the outside based on the absorbed power is: predicting the power loss after the electromagnetic signal is radiated to the outside; predicting the average electric field strength after the electromagnetic signal is radiated to the outside based on the absorbed power and the power loss; predicting the specific absorption rate of the electromagnetic signal relative to the human body after being radiated to the outside based on the average electric field strength. As one of the implementations, the power loss prediction formula is L=32.44+20lg(d)+20lg(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 of the implementations, the specific absorption rate prediction formula is SAR=(σ|E 2 |) / ρ, σ represents the human body conductivity (generally, the range of human body conductivity is 0.5~2S / m), ρ represents the human tissue density, E represents the average electric field strength, and SAR represents the specific absorption rate. In addition, it should be noted that the electromagnetic monitoring unit 141 can communicate with external smart terminals such as mobile phones, smart wearable devices, tablet computers and laptops in a wired or wireless manner, and send various data detected or predicted during the electromagnetic monitoring process (such as absorbed power, power loss, average electric field strength, specific absorption rate, etc.) to the smart terminal, and the smart terminal can visualize the data it receives to the user, so that the user can more intuitively understand the electromagnetic leakage of the aerosol generating device.

[0016] It is understandable that in the process of the electromagnetic monitoring unit 141 judging whether there is an electromagnetic exposure risk based on the absorbed power, the data involved, such as power loss, average electric field strength, specific absorption rate, etc., are all predicted and estimated, rather than calculated accurate data. In other words, the electromagnetic monitoring unit 141 can estimate the electromagnetic leakage of the aerosol generating device through certain prediction and estimation models, thereby predicting these data, such as the Kalman filter model and its variants, machine learning models, etc. Further, Figure 2 It is a power estimation diagram of the leaked electromagnetic signal radiated to the outside. Assuming that there are four electromagnetic monitoring antennas 150, 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 150, and the observed sample represents the absorbed power output by the port of each electromagnetic monitoring antenna 150 due to the absorption of the corresponding electromagnetic signal. The estimated trajectory represents the power of the leaked electromagnetic signal radiated to the outside, which is predicted and estimated after the observed sample (i.e., the absorbed power) is processed by Kalman filtering. In addition, it should be noted that the electromagnetic monitoring unit 141 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 electromagnetic monitoring unit 141 can also predict and estimate whether the leaked electromagnetic signal will destroy the electromagnetic compatibility of the aerosol generating device based on the absorbed power. Once it is predicted and estimated that the electromagnetic compatibility of the aerosol generating device will be destroyed, the power supply 160 can be directly controlled to be turned off; specifically, the electromagnetic monitoring unit 141 can 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 the interference of the leaked electromagnetic signal, the power supply 160 can be directly controlled to be turned off, thereby avoiding damage to the various structures in the aerosol generating device due to electromagnetic interference.

[0017] Generally, for an electronic atomization device, a nozzle connected to the interior of the shell is usually provided on the shell, and the user can hold the nozzle with his lips and perform a suction action, thereby inhaling the aerosol atomized by the aerosol generator when heated. Based on this, the lip contact data generated when the user's lips contact the outer surface of the nozzle can be used to determine whether the user is / is about to perform a suction action, so as to find the right time to heat the aerosol generator and atomize it into aerosol. In one embodiment, see Figure 1In addition to the structures listed above, the aerosol generating device also includes a microwave generating circuit 110, a power amplifier circuit 120 and a microwave output circuit 130. The microwave generating circuit 110, the power amplifier circuit 120 and the microwave output circuit 130 are connected in sequence. The microwave generating circuit 110 and the power amplifier circuit 120 are respectively connected to a single-chip microcomputer 140. In addition to an electromagnetic monitoring unit 141, the single-chip microcomputer 140 is also provided with a feedback unit 142 and a control unit 143. During the actual heating process of the aerosol generator, the feedback unit 142 can obtain the lip contact data between the user's lips and the outer surface of the mouthpiece, and the control unit 143 can determine whether the user has inhaled the aerosol generating device according to the lip contact data, and output the microwave generation instruction and the power amplification instruction when it is determined that the inhalation event has occurred, and the microwave generation circuit 110 can respond to the microwave generation instruction to output the initial microwave signal, and the power amplification circuit 120 can respond to the power amplification instruction to enter the conduction state that allows signal transmission, and amplify the initial microwave signal to obtain the target microwave signal, and 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 heat the aerosol generator and atomize it into an aerosol for the user to inhale. Preferably, the microwave generation circuit 110 of the present application has the ability to self-regulate the output frequency, that is, the microwave generation 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.

[0018] It is understandable that the microwave generating circuit 110 will not generate an initial microwave signal when it has not received the microwave generating instruction sent by the control unit 143, and the power amplifying circuit 120 will not allow signal transmission when it has not received the power amplifying instruction sent by the control unit 143, that is, it will 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 amplify any signal to obtain the target microwave signal. When the user is sucking, he will inevitably hold the mouthpiece with his lips and perform the suction action. Based on this, the present application determines that the user has sucked the aerosol generating device according to the lip contact data. When the user inhales, it can be considered that now is the time to heat the aerosol generator and atomize it into aerosol. Then, when the user inhales, 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 utilize the power amplifier circuit 120 to amplify 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 120 to the microwave radiator, and the microwave radiator will radiate the received target microwave signal to the aerosol generator, thereby realizing heating of the aerosol generator when the user inhales.

[0019] In some implementations of this embodiment, see Figure 1 A sensor cluster 170 is arranged on the outer surface of the nozzle. The sensor cluster 170 is composed of at least one sensor. When the sensor cluster 170 includes multiple sensors, the multiple sensors are distributed at different positions on the nozzle. Each sensor in the 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 the user's irritation when holding the nozzle with his lips. The sensor cluster 170 can collect lip contact data in real time by relying on its own sensors, and transmit the collected lip contact data to the feedback unit 142 in the single-chip computer 140. As one of the implementation methods, each sensor in the sensor cluster 170 adopts 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 feedback unit 142 in the single-chip computer 140 can transmit this pressure data to the control unit 143. The control unit 143 can compare the 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 unit 143 will send a microwave generation instruction to the microwave generating circuit 110 and a power amplification instruction to the power amplification circuit 120, thereby realizing the heating of the aerosol generator when the user inhales.

[0020] In some implementations of this embodiment, the power amplifier circuit 120 has several different power amplification levels, and the power of the target microwave signal output by the power amplifier circuit 120 is positively correlated with its own power amplification level, that is, the higher the power amplification level of the power amplifier circuit 120, the greater the power of the target microwave signal output, and the greater the power of the target microwave signal, the shorter the time for aerosol to be atomized when the aerosol generator is heated. Based on this, the user can adjust the power amplification level of the power amplifier circuit 120 at any time according to his own puffing situation, that is, the user can send power adjustment information to the control unit 143, and the control unit 143 can send a corresponding power adjustment instruction to the power amplifier circuit 120 after receiving the power adjustment information input by the user, and the power amplifier circuit 120 can respond to the power adjustment instruction and adjust its own power amplification level accordingly, so as to amplify the initial microwave signal based on the adjusted power amplification level to obtain the target microwave signal. As one of the implementation methods, the power amplifier circuit 120 includes a plurality of power amplifiers, and the connection form between the plurality of power amplifiers is adjustable. The present application can change the power amplification level of the power amplifier circuit 120 by adjusting the connection form between the plurality of power amplifiers, that is, change the power of the target microwave signal output by the power amplifier circuit 120, such as adjusting the number of power amplifiers connected together in the power amplifier circuit 120 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.

[0021] For example, see Figure 1The 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 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 to the microwave output circuit 130. Specifically, the power amplification level of the power amplifier circuit 120 includes one level and two levels; wherein, at 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 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 three, namely the first power amplifier AM1, the second power amplifier AM2 and the third power amplifier AM3, and the power of the target microwave signal output by the power amplifier circuit 120 is relatively small; at the second 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 of the target microwave signal output by the power amplifier circuit 120 is relatively large. Further, Figure 3 is a power diagram of the target microwave signal in different heating control stages, wherein the second stage corresponds to the power of the target microwave signal under the first-level power amplification level, the third stage corresponds to the power of the target microwave signal under the second-level power amplification level, and the first stage corresponds to the situation when the user does not inhale, at which 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, so the power of the target microwave signal in this stage is zero.

It can be understood that through the implementation of the above embodiments of the present application, in the process of heating the aerosol generator, there is electromagnetic leakage on the microwave radiator and / or the aerosol generator, and the leaked electromagnetic signal can be absorbed by the electromagnetic monitoring antenna 150 and generate absorption power accordingly, and the electromagnetic monitoring unit 141 in the single-chip computer 140 can determine whether there is an electromagnetic exposure risk based on the absorption power, and send a power-off instruction to the power supply 160 to instruct the power supply 160 to shut down when it is determined that there is an electromagnetic exposure risk. In other words, the present application can perform real-time electromagnetic leakage monitoring, thereby preventing users from being exposed to the electromagnetic environment for a long time and causing damage to the user's body.
