相关申请的交叉参考
本申请要求于2021年03月04日提交中国专利局，申请号为202110242013.X，申请名称为“气雾生成装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及加热不燃烧烟具技术领域，尤其涉及一种气雾生成装置。
背景技术
烟制品(例如，香烟、雪茄等)在使用过程中燃烧烟草以产生烟草烟雾。人们试图通过制造在不燃烧的情况下释放化合物的产品来替代这些燃烧烟草的制品。
此类产品的示例为加热装置，其通过加热而不是燃烧材料来释放化合物。例如，该材料可为烟草或其他非烟草产品，这些非烟草产品可包含或可不包含尼古丁。作为另一示例，现有技术提出了一种电磁感应加热式的加热装置，其构造可参见图1所示；当烟制品1被接收在加热装置内时，感受器2被感应线圈3产生的交变磁场穿透从而感应发热，进而对烟制品1进行加热。在加热的过程中为了便于实时监测对烟制品1加热的温度，加热装置采用一与感受器2紧密贴合的温度传感器4感测感受器2的实时操作温度，并根据温度传感器4感测的结果调节感应线圈3产生的交变磁场的参数，使感受器2处于适当的加热温度范围。
以上加热装置在实施中，当感应线圈3产生交变磁场诱导感受器2加热的过程中，电路处于高功率输出的大负载状态、电源输出电流较大，相对地输出的电压下降并抖动剧烈，进而在这一过程中采样温度传感器 4的结果时由于供电电压过低存在较大的纹波或信噪，影响了采样结果的准确性。
针对以上情形，作为现有技术201880084762.0号专利提出了在采样温度传感器的感测结果时避开或中断交变磁场，以消除对温度采样结果的干扰。以上实施中温度采样无法实时进行，仅能在加热中断或停止的间隙进行，影响加热的进度并容易导致温度存在较大的过冲。

具体实施方式
为了便于理解本申请，下面结合附图和具体实施方式，对本申请进行更详细的说明。
本申请的一实施例提出一种气雾生成装置，其构造可以参见图1所示，包括：
腔室，气溶胶生成制品A可移除地接收在腔室内；
电感线圈L，用于在交变电流下产生变化磁场；
感受器30，至少一部分在腔室内延伸，并被配置为与电感线圈L感应耦合，在被变化磁场穿透下发热，进而对气溶胶生成制品A例如烟支进行加热，使气溶胶生成制品A的至少一种成分挥发，形成供抽吸的气溶胶；
温度传感器40，用于感测感受器30的温度；
电芯10，为可充电的直流电芯，可以输出直流电流；
电路20，通过适当的电连接到可充电的电芯10，用于从将电芯10输出的直流电流，转变成具有适合频率的交变电流再供应到电感线圈L 以驱动电感线圈L产生变化磁场。同时，电路20还用于采样或接收温度传感器40感测的温度结果，并根据该温度结果控制输出给电感线圈L的电流或功率。
根据产品使用中的设置，电感线圈L可以包括绕成螺旋状的圆柱形电感器线圈，如图1中所示。绕成螺旋状的圆柱形电感线圈L可以具有范围在大约5mm到大约10mm内的半径r，并特别地半径r可以大约为7mm。绕成螺旋状的圆柱形电感线圈L的长度可以在大约8mm到大约14mm的范围内，电感线圈L的匝数大约8匝到15匝的范围内。相应地，内体积可能在大约0.15cm 3至大约1.10cm 3的范围内。
在更加优选的实施中，电路20供应到电感线圈L的交变电流的频率介于80KHz～400KHz；更具体地，频率可以在大约200KHz到300KHz的范围。
在一个优选的实施例中，电芯10提供的直流供电电压在约2.5V至约9.0V的范围内，电芯10可提供的直流电流的安培数在约2.5A至约20A的范围内。
在一个优选的实施例中，感受器30大体呈销钉或者刀片状的形状，进而对于插入至气溶胶生成制品A内是有利的；同时，感受器30可以具有大约12毫米的长度，大约4毫米的宽度和大约0.5毫米的厚度，并且可以由等级430的不锈钢(SS430)制成。作为替代性实施例，感受器30可以具有大约12毫米的长度，大约5毫米的宽度和大约0.5毫米的厚度，并且可以由等级430的不锈钢(SS430)制成。在其他的变化实施例中，感受器30还可以被构造成圆筒状或管状的形状；在使用时其内部空间形成用于接收气溶胶生成制品A的腔室，并通过对气溶胶生成制品A的外周加热的方式，生成供吸食的气溶胶。这些感受器还可以由等级420的不锈钢(SS420)、以及含有铁/镍的合金材料(比如坡莫合金) 制成。
在可选的实施中，感受器30是由以上感受性的材质制备的，或者是由陶瓷等耐热的基体材质外表面上电镀、沉积等形成感受材料涂层获得的。
在优选的实施中，温度传感器40在实施中可以是热敏电阻式的传感器如PT1000等，还可以是通过检测热电势进而获取温度的热电偶例如常用的J型或K型热电偶。在图2中所示，温度传感器40是被封装于销钉或片状的感受器30内的，并通过其所具有的细长的导电丝或电引脚等贯穿至感受器30外部与电路20连接。在其他的可选实施中，温度传感器40是紧贴感受器30外部表面或焊接在感受器30上的。
以上由电路20在一个优选的实施方式中的结构和基本组件可以参见图3至图4所示，包括：
LC振荡器24，由电容C1与电感线圈L组成，进而电芯10通过对其提供脉冲电压使其振荡，产生供应到电感线圈L的变化的电流，从而产生变化的磁场诱导感受器30发热；在图4所示的优选实施中，该LC振荡器24是电容C1与电感线圈L并联组成的并联LC振荡器24，而在其他的变化实施中，还可以是电容C1与电感线圈L串联组成的串联LC振荡器24。
晶体管开关23用于在电芯10与LC振荡器24之间引导电流使LC振荡器24振荡，形成流过电感线圈L的变化的电流。在图4所示的实施中，晶体管开关23包括第一开关管Q1，交替的导通和关闭，以在电芯10与LC振荡器24之间引导电流使LC振荡器24振荡，形成流过电感线圈L的变化的电流。当然，在图4所示的优选实施中，第一开关管Q1是常用的MOS管开关，连接中MOS管开关根据G极接收开关管驱动22的PWM驱动信号进而导通/断开。在其他的变化实施中，例如配合串 联的串联LC振荡器24中，可以通过更多的晶体管开关23组成的全桥/半桥驱动串联LC振荡器24振荡等。
进一步在优选的实施中，晶体管开关23的导通和断开是由开关管驱动22的驱动信号控制的。例如图4中采用的常用的FD2204开关驱动器。当然，开关管驱动22的驱动信号是基于接收的MCU控制器21发出的PWM方式的脉冲控制信号发出的。
进一步在图2所示的优选实施中，电路20包括有采样温度传感器40的感测结果的采样模块25。MCU控制器21根据采样模块25采样获得的温度传感器40的感测温度，控制LC振荡器24的频率、周期等参数进而改变提供给感受器30的功率，使感受器30的加热温度能与所需的预设目标值保持相同或基本相同。
进一步通常在实施中，加热过程中电芯10需要持续提供大的输出电流，而产品中由于电芯10容量有限则只能通过降低输出电芯10正端的输出电压来保证较高的输出电流，进而使电芯10正端的输出电压在加热过程中波动剧烈。参见图3所示，电路20中为了消除在温度采样过程中由电芯10输出的电压波动剧烈造成的纹波，采样模块25的工作由升压模块26升压后经稳压模块28稳定供电。当然升压模块26输出的电压由开关模块27选择性地输出给稳压模块28。具体，在一个实施例中升压模块26的器件结构参见图5所示，包括：
DC-DC升压芯片261，在图5中优选采用的是常用的微源半导体LP6216B6F的升压芯片，用于将电芯10输出的电压(约为4.5V)转换成6.0V的标准输出电压。
进一步参见图2和图6，由DC-DC升压芯片261输出的6.0V电压经开关模块27选择性提供给稳压模块28；而后由稳压模块28调整后稳定输出给采样模块25；其中，
开关模块27在图6中主要包括有第二开关管Q2和第三开关管Q3；当第二开关管Q2导通而第三开关管Q3断开时，由电芯10的输出作为稳压模块28的输入级；而当第二开关管Q2断开而第三开关管Q3导通时，则由DC-DC升压芯片261的输出作为稳压模块28的输入级；
稳压模块28包括有两个串联的稳压器，即分别为图6中的RY6211B SOT23-5型第一LDO(低压差线性稳压)稳压器281和第二LDO稳压器282；其中第一LDO稳压器281的稳压输出为3.3V，第二LDO稳压器282的稳压输出为3.0V。第二LDO稳压器282的输出电压小于第一LDO稳压器281的输出电压，将电压递减的方式进行稳压输出有利于纹波和信噪。在其他更多的变化实施中，在保证能提供给采样模块25足够稳定工作电压的情形下，稳压模块28还可以包括继续串联输出电压依次降低的更多LDO稳压器。
采样以上具有二级LDO的稳压模块28来输出提供采样模块25的工作电压，能相应大大减小电芯10的纹波造成采样结果不准确的问题。具体，假设加热过程中电芯10的纹波为0.24V，以所购买选用的RY6211B SOT23-5型LDO稳压器的PSRR(电源纹波抑制比)为70dB计算；经过一级LDO(3.3V)后，输出电压的纹波约＝0.24/10 70/20＝76uV，而通常采用的K型热电偶(分辨精度为42uV/0.1度)最小要求纹波为4.2uV；因此仅有一级LDO是不够的。当进一步包含二极LDO(3.0V)时，便会获得双倍的PSRR，此时输出电压的纹波约＝0.24/10 (70+70)/20＝0.024uV；则二级LDO相比一级LDO大大降低了纹波干扰。
进一步为了使采样模块25自身同样准确获取温度传感器40所感测的结果，图7出了一个实施例中包括有用于采样K型热电偶式的温度传感器40的结构示意图。在该实施例中采样模块25包括：用于采样K型热电偶的热端相对冷端的热电势的第一采样单元251、以及用于采样K 型热电偶冷端电势的第二采样单元252。
具体在图8中示出了一个实施例的第一采样单元251的器件组成，包括：基准电压源U1、电压跟随器U2、差分运算放大器U3、二阶滤波器2511；在实施中工作原理为：
基准电压源U1(即ADI芯片)用于将输入的标准电压Vcc依次经稳压、分压电阻R3/R4分压后，输出为后级电路提供精确稳定的2.5V的基准电压PP2V5；在实施中，基准电压源U1采用常规的REF3025、ADR03ARZ、LM385BLP、LM385BPW等宽工作电流和输出电压的ADI芯片；通常这些ADI芯片的工作电流介于15uA～20mA、输出电压介于50mV～5V；
电压跟随器U2，具有输入阻抗大、输出阻抗小的特点，进而用来隔离分压电阻R3/R4与差分放大单元U3，使其差分运算放大倍数不受分压电阻R3/R4的影响，为差分放大单元U3提供精确的偏置电压，实施中偏置电压为1.0V；
差分运算放大器U3的采样端in+/in-分别连接至K型热电偶40的正/负极电引脚连接，例如图8中N+/N-为K型热电偶40的正/负极电引脚的接入，进而用于采样K型热电偶40的热端对冷端的热电势。
在优选的实施中，差分运算放大器U3采用稳定性高于普通运放的零漂移运放进行；同时，为了稳定差分运算放大器U3的采样和运算，由电容C5和电容C6作为供电电压的滤波；以及由电容C3、电阻R5和电阻R6提供正相端in+的输入信号，由电容C4、电阻R7和电阻R8提供反相端in-的输入信号。
则在图8所示的实施例中，差分运算放大器U3工作中通过采样N+/N-的电势后运算输出的结果Vout＝PP2V5﹒R4/(R3+R4)+a﹒ΔV；式中a为差分运算放大器U3设置的运放参数、ΔV为采样的热电偶冷热两端的电势差；
而后进一步以上运算的结果经由二阶滤波器2511稳定输出至MCU控制器21。
进一步参见图9，图9示出了一个以通常第二采样单元252的示意图；第二采样单元252以与热电偶40的冷端毗邻或连接的NTC电阻R1来获取K型热电偶的冷端电势、并与标准电阻R2构建分压，再由基准电压源U1的供电电压PP2V5作为电压输入即可通过检测NTC电阻R1的电压获取热电偶的冷端电势。基于K型热电偶的冷端补偿原理采样，则MCU控制器21将第二采样单元252采样的K型热电偶的冷端电势、与第一采样单元251采样获取的热端相对冷端的热电势进行加法运算，而后查表即可获得感受器30的实时温度。
以上第一采样单元251以基准电压源U1为MCU控制器21的结果接收提供高稳定、高精度的校准，并由电压跟随器U2、差分运算放大器U3进行零漂移的精确运算后二阶滤波输出，使采样和运算过程中信号不受电路20的其他负载的影响，提升了准确性。
进一步在更加优选的实施中，使电路20的进行采样运算的模拟部分、以及升压驱动的数字部分等之间的接地分别采用不同的接地方式，例如图4、图6和图8中采用的直接接地、等电势接地、接外壳接地；并对不同的接地之间采用大电阻或磁珠等电子领域隔离措施进行隔离，已屏蔽它们之间的信噪干扰，例如图4中的隔离电阻R8。
进一步在以上电路20各模块中，还包括有若干基本元器件，例如电阻、电容、二极管等，它们在各模块中承担常规的降压、限流、滤波等基础功能。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但并不限于本说明书所描述的实施例，进一步地，对本领域普 通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
