下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
图1是本发明气溶胶生成装置实施例一的逻辑结构图,首先说明的是,气溶胶生成装置包括有容置腔(未示出)、发热体30,其中,容置腔用于容置气溶胶生成基质40,发热体30用于对气溶胶生成基质40进行加热,例如,发热体30可内嵌于气溶胶生成基质40中。而且,发热体30为具有磁温特性的发热体,即,为具有特定居里温度点的合金,在特定居里温度点(例如420℃)以下,其磁感值随温度升高而减小,且几乎呈线性关系。发热体30的材料例如可选用铁镍铬合金。Figure 1 is a logical structure diagram of Embodiment 1 of the aerosol generating device of the present invention. Firstly, it is explained that the aerosol generating device includes an accommodating cavity (not shown) and a heating element 30, wherein the accommodating cavity is used for accommodating The aerosol generating substrate 40 and the heating element 30 are used to heat the aerosol generating substrate 40 , for example, the heating element 30 can be embedded in the aerosol generating substrate 40 . Moreover, the heating element 30 is a heating element with magnetic-temperature characteristics, that is, it is an alloy with a specific Curie temperature point. Below the specific Curie temperature point (for example, 420° C.), its magnetic inductance value decreases as the temperature increases. , and the relationship is almost linear. The material of the heating element 30 can be iron-nickel-chromium alloy, for example.
结合图1,该实施例的气溶胶生成装置还包括控制模块11、谐振模块12和加热模块13,而且,加热模块13包括加热线圈L2,该加热线圈L2套设在容置腔上;谐振模块12包括检测线圈L1,该检测线圈L1的至少一部分处于发热体30的磁场内。在该实施例中,检测线圈L1、加热线圈L2均为螺旋式弹簧线圈,且该检测线圈L1、加热线圈L2均套设在容置腔上,例如可为同轴套叠,优选地,可将加热线圈L2设置在检测线圈L1的外部。1, the aerosol generating device of this embodiment also includes a control module 11, a resonance module 12 and a heating module 13, and the heating module 13 includes a heating coil L2, which is sleeved on the accommodating cavity; the resonance module 12 includes a detection coil L1 , at least a part of which is located within the magnetic field of the heating element 30 . In this embodiment, the detection coil L1 and the heating coil L2 are helical spring coils, and the detection coil L1 and the heating coil L2 are both sleeved on the accommodating cavity, for example, they can be nested coaxially, preferably, The heating coil L2 is provided outside the detection coil L1.
控制模块11分别与谐振模块12及加热模块13相连,而且,控制模块11用于通过控制加热模块12使加热线圈L2上产生交变电流,以对容置腔中的发热体30进行电磁加热;还用于控制谐振模块12工作在谐振状态,这样在检测时几乎不产生感应发热,实际工作时电流很小,同时,还根据检测线圈L1的电压信号确定谐振模块12的谐振频率,并根据该谐振频率确定相应的检测结果,例如包括发热体的温度、是否发生抽吸动作、是否发生气溶胶生成基质的插入动作。The control module 11 is connected to the resonance module 12 and the heating module 13 respectively, and the control module 11 is used to generate an alternating current on the heating coil L2 by controlling the heating module 12, so as to electromagnetically heat the heating element 30 in the accommodating cavity; It is also used to control the resonant module 12 to work in a resonant state, so that there is almost no induction heating during detection, and the current is very small during actual operation. At the same time, the resonant frequency of the resonant module 12 is determined according to the voltage signal of the detection coil L1, and according to this The resonance frequency determines the corresponding detection results, including, for example, the temperature of the heating element, whether a suction action occurs, and whether an insertion action of an aerosol-generating substrate occurs.
在该实施例中,气溶胶生成装置在正常工作的过程中,发热体30的温度会发生变化,例如,一个控制周期内的加热时段与非加热时段的温度不同;发生抽吸动作与未发生抽吸动作时的温度不同,发热体30温度的变化会引起其磁感值的变化。另外,气溶胶生成装置中在有气溶胶生成基质插入及未有气溶胶生成基质插入的不同情况下,发热体30的磁感值也是不同的。这样,当发热体30磁感值发生变化时,由于检测线圈L1的至少一部分处于发热体30的磁场内,从而使得谐振模块12的谐振频率发生变化,即,检测线圈L1上电压的频率发生变化,所以可将频率特征作为气溶胶生成装置的相应检测结果的表征,因此,控制模块11便可根据谐振频率确定出相应的检测结果。这种检测方式由于不需要设置温度传感器,解决了气溶胶生成装置结构设计受限的问题,而且,由于检测线圈L1不需要与发热体进行电气连接,也解决了因电气连接引起的清洁困难问题。另外,通过谐振模块与加热模块的分离,可实现加热模块的灵活设计。In this embodiment, during the normal operation of the aerosol generating device, the temperature of the heating element 30 will change. For example, the temperature of the heating period and the non-heating period in a control cycle are different; The temperature during the pumping action is different, and the change of the temperature of the heating element 30 will cause the change of its magnetic induction value. In addition, the magnetic inductance value of the heating element 30 is also different in the case of an aerosol generating substrate inserted or not inserted in the aerosol generating device. In this way, when the magnetic inductance value of the heating element 30 changes, since at least a part of the detection coil L1 is in the magnetic field of the heating element 30, the resonant frequency of the resonance module 12 changes, that is, the frequency of the voltage on the detection coil L1 changes , so the frequency feature can be used as a representation of the corresponding detection result of the aerosol generating device, therefore, the control module 11 can determine the corresponding detection result according to the resonant frequency. Since this detection method does not require a temperature sensor, it solves the problem of limited structural design of the aerosol generating device. Moreover, since the detection coil L1 does not need to be electrically connected to the heating element, it also solves the problem of cleaning difficulties caused by the electrical connection. . In addition, through the separation of the resonant module and the heating module, the flexible design of the heating module can be realized.
另外,还需说明的是,在其它实施例中,也可选用其它方式对发热体30进行加热,例如,直接加热方式。In addition, it should be noted that, in other embodiments, other ways can also be used to heat the heating element 30 , for example, direct heating.
图2是本发明气溶胶生成装置实施例二的结构示意图,该实施例相比图1所示的实施例,所不同的仅是:发热体30为扁平长方体,检测线圈包括四个相串联的螺旋式扁平线圈L11、L12、L13、L14,而且,该四个螺旋式扁平线圈L11、L12、L13、L14分散设置在发热体30的外围,即,设置在容置腔的外围,检测线圈为多面感应的布置形式。关于该实施例,需说明的是,由于发热体30为扁平长方体,检测线圈也为螺旋式扁平线圈,而且,实际应用中在进行气溶胶生成基质的插拔后,发热体30有可能绕其竖直轴进行了旋转,即,在水平面的投影形状发生了变化,进而有可能发生发热体30的扁平面刚好与一个螺旋式扁平线圈的扁平面相垂直或者接近垂直,这种情况下,由于对谐振模块的谐振频率的影响较小,所以有可能导致检测结果不准确。为避免这种情况的发生,该实施例在发热体30的外围设置多个相串联的螺旋式扁平线圈,不管发热体如何绕其竖直轴旋转,均可保证螺旋式扁平线圈落入发热体30的磁场的部分足够多,从而提高了检测准确度。应理解,本发明并不限定螺旋式扁平线圈的数量,在其它实施例中,螺旋式扁平线圈的数量也可为两个、三个等。当然,在其它实施例中,若发热体为圆柱体或横截面为正方形的长方体时,也可仅设置一个螺旋式扁平线圈。Fig. 2 is a schematic structural diagram of the second embodiment of the aerosol generating device of the present invention. Compared with the embodiment shown in Fig. 1, this embodiment differs only in that the heating element 30 is a flat cuboid, and the detection coil includes four series-connected The helical flat coils L11, L12, L13, L14, and the four helical flat coils L11, L12, L13, L14 are dispersedly arranged on the periphery of the heating element 30, that is, arranged on the periphery of the accommodating cavity, and the detection coils are The arrangement form of multi-surface induction. Regarding this embodiment, it should be noted that since the heating element 30 is a flat rectangular parallelepiped, the detection coil is also a helical flat coil. Moreover, in practical applications, after the aerosol generating matrix is plugged and pulled, the heating element 30 may wind around it. The vertical axis has been rotated, that is, the projection shape on the horizontal plane has changed, and then it is possible that the flat plane of the heating element 30 is just perpendicular to or nearly vertical to the flat plane of a helical flat coil. In this case, due to the The resonant frequency of the resonant module has little influence, so it may lead to inaccurate detection results. In order to avoid the occurrence of this situation, in this embodiment, a plurality of helical flat coils connected in series are arranged on the periphery of the heating element 30. No matter how the heating element rotates around its vertical axis, the helical flat coils can be guaranteed to fall into the heating element. The part of the magnetic field of 30 is enough, thereby improving the detection accuracy. It should be understood that the present invention does not limit the number of helical flat coils, and in other embodiments, the number of helical flat coils may also be two, three, etc. Of course, in other embodiments, if the heating element is a cylinder or a rectangular parallelepiped with a square cross section, only one helical flat coil may be provided.

结合图3及图4,第三开关管Q3、第四开关管Q4、加热线圈L2、第二电容C2及第三电容C3构成可控的加热模块,在需要对发热体进行加热控制时,控制模块中的主控单元通过PWM-H、PWM-L控制第三开关管Q3、第四开关管Q4交替导通可在加热线圈L2上产生交变电流,从而实现发热体的可控加热。3 and 4, the third switching tube Q3, the fourth switching tube Q4, the heating coil L2, the second capacitor C2 and the third capacitor C3 constitute a controllable heating module, when it is necessary to control the heating of the heating element, the control The main control unit in the module controls the third switching tube Q3 and the fourth switching tube Q4 to be turned on alternately through PWM-H and PWM-L to generate alternating current on the heating coil L2, thereby realizing controllable heating of the heating element.
检测线圈L1、第一电容C1及附属电路构成谐振模块,运放U1B及附属电路构成转换单元。当需要进行相应检测时,控制模块中的主控单元通过VCC2_EN控制第五开关管Q5导通,此时VCC2为高电平,检测线圈L1与第一电容C1进行谐振,检测线圈L1上产生波形震荡的电压信号,该电压信号被送入运放U1B。运放U1B将该波形震荡的电压信号转变为可进行频率测量的脉冲信号,同时,通过电阻R7、R9实现电平匹配,然后将输出信号Fre传送到控制模块的主控单元,主控单元通过频率测量获取谐振模块当前谐振频率的特征,然后通过谐振频率的特征变化进行相应的检测,而且,利用谐振频率的特征变化可实现多种检测:The detection coil L1, the first capacitor C1 and the auxiliary circuit form a resonant module, and the operational amplifier U1B and the auxiliary circuit form a conversion unit. When corresponding detection is required, the main control unit in the control module controls the fifth switch tube Q5 to be turned on through VCC2_EN. At this time, VCC2 is at a high level, and the detection coil L1 resonates with the first capacitor C1, and a waveform is generated on the detection coil L1 The oscillating voltage signal is sent to the operational amplifier U1B. The operational amplifier U1B converts the oscillating voltage signal into a pulse signal that can be used for frequency measurement. At the same time, the level matching is realized through the resistors R7 and R9, and then the output signal Fre is sent to the main control unit of the control module. The main control unit passes Frequency measurement obtains the characteristics of the current resonant frequency of the resonant module, and then performs corresponding detection through the characteristic change of the resonant frequency. Moreover, various detections can be realized by using the characteristic change of the resonant frequency:
在一个可选实施例中,利用谐振频率的特征变化实现发热体温度的检测,具体地,控制模块用于在对所述发热体进行功率控制时,在每个周期的加热时段,根据所述发热体的温度控制所述加热模块产生交变电流;在每个周期的非加热时段,控制所述谐振模块工作在谐振状态,而且,根据所述谐振模块的谐振频率确定所述发热体的温度。在该实施例中,在控制模块的控制下,在加热线圈上加载特定时间段(Tm)的交变电流,发热体进行感应发热。而发热体在特定温度情况下(例如150~420℃间)具备明显的磁温特性。然后,控制模块在另一特定时间段(Tn)控制谐振模块工作,Tm、Tn为不重合的两个时间段,由于谐振模块的频率特征变化可反馈出发热体温度的变化,所以,控制模块可通过对检测线圈上的电压进行检测来获取谐振模块的峰值频率特征,再根据该频率特征的变化确定出发热体温度的变化,并根据发热体温度的变化来调整加热线圈上的交感电流。而且,该加热方式由于为感应加热方式,所以具备较大的转换功率,同时,谐振模块工作在谐振状态,几乎不产生明显的感应发热,实际工作时工作电流很小。In an optional embodiment, the detection of the temperature of the heating element is realized by using the characteristic change of the resonant frequency. Specifically, the control module is used to control the power of the heating element, during the heating period of each cycle, according to the The temperature of the heating body controls the heating module to generate an alternating current; during the non-heating period of each cycle, the resonance module is controlled to work in a resonance state, and the temperature of the heating body is determined according to the resonance frequency of the resonance module . In this embodiment, under the control of the control module, the heating coil is loaded with an alternating current for a specific time period (Tm), and the heating element performs induction heating. The heating element has obvious magnetic-temperature characteristics at a specific temperature (for example, between 150 and 420°C). Then, the control module controls the resonant module to work in another specific time period (Tn). Tm and Tn are two time periods that do not overlap. Since the frequency characteristic change of the resonant module can feed back the change of the heating body temperature, the control module The peak frequency characteristic of the resonant module can be obtained by detecting the voltage on the detection coil, and then the change of the temperature of the heating element can be determined according to the change of the frequency characteristic, and the sympathetic current on the heating coil can be adjusted according to the change of the temperature of the heating element. Moreover, since the heating method is an induction heating method, it has relatively large conversion power. At the same time, the resonant module works in a resonant state, which hardly produces obvious induction heating, and the working current is very small during actual operation.
在一个可选实施例中,利用谐振频率的特征变化实现抽吸动作的检测,具体地,由于当气溶胶生成基质中有抽吸气流流过时,发热体会出现明显温度变化,因此可通过谐振频率特征的明显跳变来实现抽吸动作的检测,进而进行抽吸口数的计量。In an optional embodiment, the detection of the pumping action is realized by using the characteristic change of the resonant frequency. Specifically, since the temperature of the heating body changes significantly when the aerosol-generating matrix has a suction airflow flowing through it, the resonant frequency can be used to detect the pumping action. The obvious jump of the characteristics is used to detect the suction action, and then to measure the number of puffs.
在一个可选实施例中,利用谐振频率的特征变化实现气溶胶生成基质的插入检测,具体地,谐振模块的工作电流很小,可在气溶胶生成装置处于待机状态下,控制模块通过“VCC2_EN”信号定时唤醒来检测谐振模块工作频率的变化,从而实现气溶胶生成基质的插入检测。In an optional embodiment, the insertion detection of the aerosol-generating substrate is realized by using the characteristic change of the resonant frequency. Specifically, the working current of the resonant module is very small. "The signal wakes up regularly to detect the change of the operating frequency of the resonant module, thereby realizing the insertion detection of the aerosol-generating substrate.
综上,结合图5,在0~t1时段,此时未加入气溶胶生成基质,所检测到的谐振频率为f0;在t1时刻,加入了气溶胶生成基质,所检测到的谐振频率降为f1;在t1~t2时段,由于开始进行预热,所检测到的谐振频率逐步上升到f2,其中,f2为预设温度点所对应的频率,而且通过控制加热是所检测到的谐振频率保持在该频率点;在t3~t4时段,由于用户进行了一次抽吸,此时,发热体温度下降,所检测到的谐振频率由f2下降至f3,然后通过加热控制使谐振频率上升至f2。同样地,在t5~t6时段,由于用户又进行了一次抽吸,所检测到的谐振频率由f2下降至f4,然后再通过加热控制使谐振频率上升至f2。而且,抽吸深度不一样时,频率下降的幅度也会不一样,例如,由于f4小于f3,所以,第二次抽吸的抽吸深度要大于第一次抽吸的抽吸深度。In summary, combined with Figure 5, during the period 0~t1, when no aerosol-generating matrix is added, the detected resonance frequency is f0; at time t1, when the aerosol-generating matrix is added, the detected resonance frequency drops to f1; during the t1~t2 period, due to the start of preheating, the detected resonant frequency gradually rises to f2, where f2 is the frequency corresponding to the preset temperature point, and the detected resonant frequency is maintained by controlling the heating At this frequency point; during the period of t3~t4, because the user has performed a puff, at this time, the temperature of the heating element drops, and the detected resonant frequency drops from f2 to f3, and then the resonant frequency is raised to f2 through heating control. Similarly, during the period t5-t6, because the user takes another puff, the detected resonant frequency drops from f2 to f4, and then the resonant frequency is raised to f2 through heating control. Moreover, when the suction depth is different, the range of frequency drop will also be different. For example, because f4 is smaller than f3, the suction depth of the second puff is greater than that of the first puff.
