Description

气溶胶产生装置、控制方法、控制装置和可读存储介质 技术领域
本申请属于电子雾化技术领域,具体而言,涉及一种气溶胶产生装置的控制方法、一种气溶胶产生装置的控制装置、一种气溶胶产生装置和一种可读存储介质。
背景技术
加热不燃烧(Heat Not Burning,HNB)装置,是一种用于通过加热但不使气溶胶产生基质(经过处理的植物叶类制品)燃烧的方式的电子设备。加热装置通过高温加热到气溶胶产生基质可以产生气溶胶但是却不足以燃烧的温度,能在不燃烧的前提下,让气溶胶产生基质产生用户所需要的气溶胶。
目前市场上的加热不燃烧器具主要采用电阻加热方式,即利用中心发热片或发热针等从气溶胶产生基质中心插入至气溶胶生成基质内部进行加热。这种器具在使用前需预热等待时间长,不能抽停自由,气溶胶生成基质碳化不均匀,导致气溶胶生成基质烘烤不充分,利用率低;其次,HNB器具发热片容易在气溶胶产生基质提取器和发热片基座中产生污垢,难清洁;会使接触发热体的局部气溶胶产生基质温度过高、发生部分裂解,释放出对人体有害的物质。因此微波加热技术逐渐替代电阻加热方式成为新的加热方式。微波加热技术具有高效、及时、选择性及加热无延缓性的特点,只对特定介电特性的物质有加热效果。采用微波加热雾化的应用优势有:a、微波加热为辐射加热,非热传导,可实现即抽即停;b、无加热片,因此不存在断片、清洁发热片的问题;c、气溶胶产生基质利用率高,口感一致性高,口感更接近香烟。
但是现有微波加热的HNB器具存在空腔干烧的风险,导致器具的使用寿命降低。
申请内容
本申请旨在解决现有技术或相关技术中存在的技术问题之一。
有鉴于此,第一方面,本申请实施例提出一种气溶胶产生装置的控制方法,气溶胶产生装置包括雾化腔和微波组件,雾化腔用于容置气溶胶产生基质,微波组件用于向雾化腔馈入微波,控制方法包括:控制微波组件在微波频率范围内扫频运行,查找微波频率范围中的目标微波频率;根据目标微波频率与设定频率范围的数值关系,确定雾化腔内的气溶胶产生基质的存在状态;根据气溶胶产生基质的存在状态,控制微波组件的运行状态。
本申请提供控制方法用于控制气溶胶产生装置,气溶胶产生装置用于加热气溶胶产生基质,其中,气溶胶产生基质可为固体气溶胶产生基质或液态气溶胶产生基质。气溶胶产生装置内设置有用于容置气溶胶产生基质的雾化腔,微波组件能够向雾化腔内馈入微波,气溶胶产生基质在微波的作用下受热雾化。
气溶胶产生装置接收到开始雾化指令,控制微波组件在微波频率范围内进行扫频运行。具体地,依次按照微波频率范围内的每个微波频率控制微波组件向雾化腔内馈入微波。根据雾化腔内参数的变化从而确定微波频率范围中的目标微波频率,目标微波频率为当前雾化腔状态下,微波组件运行的最佳频率点,即雾化腔内对微波吸收量最大的微波频率。根据目标微波频率与设定频率范围的数值关系,能够判断雾化腔内气溶胶产生基质的存在状态,即雾化腔内是否容置有气溶胶产生基质。再根据雾化腔内气溶胶产生基质的存在状态,对微波组件的运行进行控制。如果检测到雾化腔内容置有气溶胶产生基质,则正常控制微波组件运行,以对气溶胶产生基质进行加热雾化,如果检测到雾化腔为空腔状态,为避免向空腔内馈入微波导致气溶胶产生装置使用寿命缩短,控制微波组件停止运行。本申请通过微波组件的扫频运行确定雾化腔当前状态下的目标微波频率,从而对雾化腔内气溶胶产生基质是否在位进行检测,避免向空腔状态下的雾化腔馈入微波,从而延长了气溶胶产生装置的使用寿命。
可以理解的是,雾化腔为空腔状态和雾化腔内容置有气溶胶产生基质的状态,通过扫频确定的目标微波频率相差较大,因而扫频得到的目标微波频率与设定频率范围的数值关系能够对雾化腔内是否容置有气溶胶产生基质进行准确判断。
另外,根据本申请提供的上述技术方案中的气溶胶产生装置的控制方 法,还可以具有如下附加技术特征:
在一种可能的设计中,根据目标微波频率与设定频率范围的数值关系,确定雾化腔内的气溶胶产生基质的存在状态的步骤,具体包括:基于目标微波频率小于设定频率范围中的最小值,确定雾化腔中的气溶胶产生基质处于未存在状态;基于目标微波频率大于设定频率范围中的最大值,确定雾化腔中的气溶胶产生基质处于存在状态;基于目标微波频率处于设定频率范围内,根据目标微波频率与设定频率范围的频率平均值的数值关系,确定雾化腔内气溶胶产生基质的存在状态。
在该设计中,设定频率范围中的最大值为雾化腔中的气溶胶产生基质处于存在状态下的最佳频率点,设定频率范围中的最小值为雾化腔处于空腔状态,即气溶胶产生基质处于未存在状态下的最佳频率点。
在检测到目标微波频率小于设定频率范围中的最小值,则判定雾化腔当前处于空腔状态,即气溶胶产生基质并未处于雾化腔中。
在检测到目标微波频率大于设定频率范围中的最大值,则判定雾化腔内的气溶胶产生基质处于存在状态,即气溶胶产生基质位于雾化腔内。
在检测到目标微波频率处于微波频率范围内,则进一步根据微波频率范围的平均值与目标微波频率的数值关系,对雾化腔内气溶胶产生基质的状态进行检测。
通过目标微波频率与设定频率范围中的数值进行比较,提高了对雾化腔内是否容置有气溶胶产生基质的判断的准确性。通过上述检测方式,能够准确地对雾化腔内是否容置有气溶胶产生基质进行检测,避免误判造成的对空雾化腔进行微波加热的情况发生。
值得说明的是,由于雾化腔处于空腔状态与雾化腔处于容置气溶胶产生基质状态的最佳频率点不同,其中,雾化腔处于空腔状态下的最佳频率点为a,雾化腔处于容置气溶胶产生基质状态的最佳频率点为b,a与b之间相差25MHZ至35MHZ,而通过扫频得到的目标微波频率通常为a±2MHZ或b±2MHZ。故将设定频率范围设置为a至b,并根据目标微波频率与a和b的数值关系,能够准确判断雾化腔内气溶胶产生基质的存在状态。

如图1所示,本申请的第一个实施例中提供了一种气溶胶产生装置的控制方法,气溶胶产生装置包括雾化腔和微波组件,雾化腔用于容置气溶胶产生基质,微波组件用于向雾化腔馈入微波。
气溶胶产生装置的控制方法包括:
步骤102,控制微波组件在微波频率范围内扫频运行,查找微波频率范围内的目标微波频率;
步骤104,根据目标微波频率与设定频率范围的数值关系,确定雾化腔内的气溶胶产生基质的存在状态;
步骤106,根据气溶胶产生基质的存在状态,控制微波组件的运行状态。
本实施例提供控制方法用于控制气溶胶产生装置,气溶胶产生装置用于加热气溶胶产生基质,其中,气溶胶产生基质可为固体气溶胶产生基质或液态气溶胶产生基质。气溶胶产生装置内设置有用于容置气溶胶产生基质的雾化腔,微波组件能够向雾化腔内馈入微波,气溶胶产生基质在微波的作用下受热雾化。
接收到开始雾化指令,控制微波组件在微波频率范围内进行扫频运行。具 体地,依次按照微波频率范围内的每个微波频率控制微波组件向雾化腔内馈入微波。根据雾化腔内参数的变化从而确定微波频率范围中的目标微波频率,目标微波频率为当前雾化腔状态下,微波组件运行的最佳频率点,即雾化腔内对微波吸收量最大的微波频率。根据目标微波频率与设定频率范围的数值关系,能够判断雾化腔内气溶胶产生基质的存在状态,即雾化腔内是否容置有气溶胶产生基质。再根据雾化腔内气溶胶产生基质的存在状态,对微波组件的运行进行控制。如果检测到雾化腔内容置有气溶胶产生基质,则正常控制微波组件运行,以对气溶胶产生基质进行加热雾化,如果检测到雾化腔为空腔状态,为避免向空腔内馈入微波导致气溶胶产生装置使用寿命缩短,控制微波组件停止运行。本申请通过微波组件的扫频运行确定雾化腔当前状态下的目标微波频率,从而对雾化腔内气溶胶产生基质是否在位进行检测,避免向空腔状态下的雾化腔馈入微波,从而延长了气溶胶产生装置的使用寿命。
可以理解的是,雾化腔为空腔状态和雾化腔内容置有气溶胶产生基质的状态,通过扫频确定的目标微波频率两者之间相差较大,因而扫频得到的目标微波频率与设定频率范围的数值关系能够对雾化腔内是否容置有气溶胶产生基质进行准确判断。
如图2所示,在上述任一实施例中,根据目标微波频率与设定频率范围的数值关系,确定雾化腔内的气溶胶产生基质的存在状态的步骤,具体包括:
步骤202,获取设定频率范围;
步骤204,判断目标微波频率是否小于设定频率范围中的最小值,判断结果为否则执行步骤206,判断结果为是则执行步骤212;
步骤206,判断目标微波频率是否大于设定频率范围内中的最大值,判断结果为否则执行步骤208,判断结果为是则执行步骤214;
步骤208,获取设定频率范围内中的频率平均值;
步骤210,判断目标微波频率是否大于频率平均值,判断结果为是则执行步骤214,判断结果为否则执行步骤212。
步骤212,确定雾化腔中气溶胶产生基质处于未存在状态,控制微波组件停止运行;
步骤214,确定雾化腔中气溶胶产生基质处于存在状态,控制微波组件按 照目标微波频率向雾化腔内馈入微波。
在该实施例中,基于目标微波频率小于设定频率范围中的最小值,确定雾化腔中的气溶胶产生基质处于未存在状态;
基于目标微波频率大于设定频率范围中的最大值,确定雾化腔中的气溶胶产生基质处于存在状态;
基于目标微波频率处于设定频率范围内,根据目标微波频率与设定频率范围的频率平均值的数值关系,确定雾化腔内气溶胶产生基质的存在状态。
设定频率范围中的最大值为雾化腔中的气溶胶产生基质处于存在状态下的最佳频率点,设定频率范围中的最小值为雾化腔处于空腔状态,即气溶胶产生基质处于未存在状态下的最佳频率点。
在检测到目标微波频率小于设定频率范围中的最小值,则判定雾化腔当前处于空腔状态,即气溶胶产生基质并未处于雾化腔中。
在检测到目标微波频率大于设定频率范围中的最大值,则判定雾化腔内的气溶胶产生基质处于存在状态,即气溶胶产生基质位于雾化腔内。
在检测到目标微波频率处于微波频率范围内,则进一步根据微波频率范围的平均值与目标微波频率的数值关系,对雾化腔内气溶胶产生基质的状态进行检测。
通过目标微波频率与设定频率范围中的数值进行比较,提高了对雾化腔内是否容置有气溶胶产生基质的判断的准确性。通过上述检测方式,能够准确地对雾化腔内是否容置有气溶胶产生基质进行检测,避免误判造成的对空雾化腔进行微波加热的情况发生。
值得说明的是,由于雾化腔处于空腔状态与雾化腔处于容置气溶胶产生基质状态的最佳频率点不同,其中,雾化腔处于空腔状态下的最佳频率点为a,雾化腔处于容置气溶胶产生基质状态的最佳频率点为b,a与b之间相差25MHZ至35MHZ,而通过扫频得到的目标微波频率通常为a±2MHZ或b±2MHZ。故将设定频率范围设置为a至b,并根据目标微波频率与a和b的数值关系,能够准确判断雾化腔内气溶胶产生基质的存在状态。
根据目标微波频率与设定频率范围的频率平均值的数值关系,确定雾化腔内气溶胶产生基质的存在状态的步骤,具体包括:
基于目标微波频率大于频率平均值,确定雾化腔中的气溶胶产生基质处于存在状态;
基于目标微波频率小于等于频率平均值,确定雾化腔中的气溶胶产生基质处于未存在状态。
在检测到目标微波频率处于微波频率范围内,则判断目标微波频率与设定频率范围的频率平均值的数值关系,并根据此数值关系进一步判断雾化腔内气溶胶产生基质的存在状态。
在检测到目标微波频率大于频率平均值时,则判定雾化腔中的气溶胶产生基质处于存在状态,即气溶胶产生基质位于雾化腔中。
在检测到目标微波频率小于等于频率平均值时,则判定雾化腔当前处于空腔状态,即气溶胶产生基质并未处于雾化腔中。
在目标微波频率处于微波频率范围内时,通过对目标微波频率与频率平均值的数值比较,能够准确判定雾化腔内气溶胶产生基质的存在状态。通过上述检测方式,能够准确地对雾化腔内是否容置有气溶胶产生基质进行检测,避免误判造成的对空雾化腔进行微波加热的情况发生。
可以理解的是,在气溶胶产生装置出厂之前,对设定频率范围中的频率进行设置。其中,设定频率范围中的最大值为雾化腔中容置有气溶胶产生基质时,微波组件向雾化腔馈入微波的最佳频率值。设定频率范围中的最小值为雾化腔处于空腔状态时,微波组件向雾化腔馈入微波的最佳频率值。
在一些实施例中,设定频率范围中包括多个设定频率值,按照从小至大的顺序排列为F 1、F 2、……F n。按照以下公式对设定频率范围的平均值进行计算:
F AVG=(F 1+F 2…+F n)/n;
其中,F AVG为频率平均值,F 1、F 2、……F n为设定频率范围中的每个频率值,n为设定频率范围中的设定频率值的数量。
在另外一些实施例中,设定频率范围中包括多个设定频率值,提取设定频率范围中的频率最小值和频率最大值,根据频率最大值和频率最小值计算得到设定频率范围中的频率平均值。按照以下公式对设定频率范围的平均值进行计算;
F AVG=(F min+F max)/2
其中,F AVG为频率平均值,F min为频率最小值,F max为频率最大值。
根据气溶胶产生基质的存在状态,控制微波组件的运行状态的步骤,具体包括:
基于气溶胶产生基质处于存在状态,控制微波组件以目标微波频率向雾化腔馈入微波;
基于气溶胶产生基质处于未存在状态,控制微波组件停止运行,输出提示信息。
在检测到气溶胶产生基质处于存在状态,即雾化腔内容置有气溶胶产生基质的情况下,判定此时能够正常对气溶胶产生基质进行微波加热雾化,控制微波组件以目标微波频率向雾化腔内馈入微波,其中,目标微波频率为微波组件通过扫频确定的微波频率,通过将目标微波频率的微波馈入雾化腔内,能够使雾化腔内的气溶胶产生基质达到最佳雾化状态,即在气溶胶产生基质能够对目标微波频率的微波吸收效果最佳,不仅减少了气溶胶产生装置的能量消耗,还进一步提高了气溶胶产生基质的雾化效率,减少气溶胶产生基质由于受热不均匀产生的有害物质。
在检测到气溶胶产生基质处于未存在装置,即雾化腔为空腔状态,雾化腔内没有气溶胶形成基质。此时控制微波组件停止运行,避免微波组件继续向处于空腔状态的雾化腔馈入微波导致的气溶胶产生装置使用寿命缩短。并且在检测到雾化腔处于空腔状态,输出提示信息,以提醒用户将气溶胶产生基质放置到雾化腔中,提高了用户的使用体验。
如图3所示,在上述任一实施例中,微波组件包括:微波生成装置和微波天线。
微波天线与微波生成装置相连,微波天线用于将微波生成装置生成的微波发射至雾化腔,以及接收反馈信号。
控制微波组件在微波频率范围内扫频运行,查找微波频率范围中的目标微波频率的步骤,具体包括:
步骤302,控制微波组件按照微波频率范围中每个微波频率,向雾化腔内发射微波;
步骤304,检测每个微波频率对应的反馈信号的反馈功率值;
步骤306,根据每个微波频率对应的反馈功率值,筛选微波频率范围中的目标微波频率。
在该实施例中,微波组件包括微波生成装置和微波天线,微波生成装置能够生成相应频率的微波,微波天线能够将相应频率的微波馈入到雾化腔内。微波进入到雾化腔后,微波天线能够接收到微波相应的反馈信号。微波组件还包括第一功率检测装置和第二功率检测装置,其中第一功率检测装置与微波生成装置相连,在微波生成装置运行过程中能够采集微波生成装置的运行功率值,第二功率检测装置与微波天线相连,能够检测微波天线接收到的反馈信号的反馈功率值。
控制微波组件按照微波频率范围内的每个微波频率向雾化腔内馈入微波,即控制微波组件依次向雾化腔内发射不同微波频率的微波。在微波组件发射微波的过程中,同时接收每个微波频率对应的反馈信号,并通过第二功率检测装置确定每个反馈信号的反馈功率值。根据检测到的反馈功率值对微波频率范围内中的目标微波频率进行筛选。从而确定雾化腔内对吸收效果最好的目标微波频率。通过扫频运行的方式,能够对微波频率范围内的微波进行筛选,从而确定当前雾化腔内吸收效果最好的目标微波频率。实现在雾化腔内容置有气溶胶产生基质的情况下,向雾化腔内馈入目标微波频率的微波,能够提高气溶胶产生基质的雾化效果。
值得说明的是,目标微波频率为微波组件对当前雾化腔内馈入微波的最佳频率点。在雾化腔处于空腔状态时,检测到的目标微波频率为向空雾化腔内馈入微波时微波组件输出微波的最佳频率点。在雾化腔处于容置有气溶胶产生基质状态时,检测到的目标微波频率为向容置有气溶胶产生基质的雾化腔内馈入微波时微波组件输出微波的最佳频率点。
如图4所示,在上述任一实施例中,根据每个微波频率对应的反馈功率值,筛选微波频率范围中的目标微波频率的步骤,具体包括:
步骤402,检测微波组件输出每个微波频率的微波对应的运行功率值;
步骤404,将每个微波频率对应的反馈功率值和运行功率值进行比值计算,以得到功率比值;
步骤406,根据每个微波频率对应的功率比值,选择微波频率范围中的目 标微波频率。
在该设计中,通过第一功率检测装置监测每个微波频率对应的运行功率值。将运行功率值与对应的反馈功率值进行比值计算,能够得到功率比值。功率比值的计算公式如下:
N=P 1/P 2
其中,P 1为反馈功率值,P 2为运行功率值,N为功率比值。
N的数值越小代表雾化腔内的微波耦合效果越好,即雾化腔内对微波的吸收效果越好。N的数值越大代表雾化腔内的微波耦合效果越差,即雾化腔内对微波吸收效果越差。
可以理解的是,N的数值范围小于1。
在一些实施例中,微波频率的数量为3个,分别为F a、F b和F c。经过计算F a对应的功率比值N a为0.1,F b对应的功率比值N b为0.5,F c对应的功率比值N c为0.3。将N a、N b和N c按照数值大小进行排列,即N a<N c<N b,由于功率比值的数值越小,则微波吸收率越高,判定控制微波组件按照功率比值Na对应的微波频率F a向雾化腔内馈入微波,能够达到最好的加热效果,因此,F a为目标微波频率。
如图5所示,在上述任一实施例中,根据每个微波频率对应的功率比值,选择微波频率范围中的目标微波频率的步骤,具体包括:
步骤502,确定每个微波频率对应的功率比值中的最小功率比值;
步骤504,查找与最小功率比值对应的微波频率,以确定目标微波频率。
在该设计中,通过将每个微波频率对应的功率比值按照数值大小进行排序,将数值最小的功率比值对应的运行频率作为目标微波频率。通过计算频率比值能够将扫频阶段的误差部分进行过滤,提高了目标微波频率筛选的准确性,从而避免了对目标微波频率的误判。
如图6所示,在上述任一实施例中,根据每个微波频率对反馈功率值,筛选微波频率范围中的目标微波频率的步骤,具体包括:
步骤602,确定每个微波频率对应的反馈功率值中的反馈功率最小值;
步骤604,查找与反馈功率最小值对应的微波频率,以确定目标微波频率。
在该设计中,直接将反馈功率值按照数值大小进行排序,从而确定反 馈功率最小值。将反馈功率最小值对应的微波频率作为目标微波频率。
可以理解的是,微波生成装置在输出不同频率的微波时的运行功率变化较小,故直接选择反馈功率最小值对应的微波频率作为目标微波频率,在保证目标微波频率选择准确性的前提下,减少了数据处理量。
实施例二:
如图7所示,本申请的第一个实施例中提供了一种气溶胶产生装置的控制方法,气溶胶产生装置包括雾化腔和微波组件,雾化腔用于容置气溶胶产生基质,微波组件用于向雾化腔馈入微波。

在该实施例中,在气溶胶产生装置接收到开始运行指令,控制微波组件对雾化腔进行扫频检测,以确定微波组件运行的目标微波频率,即微波组件向当前状态下的雾化腔馈入微波的最佳频率点。在扫频运行的过程中, 控制微波组件依次按照每个微波频率向雾化腔内馈入微波,同时接收对应的反馈信号,并确定每个反馈信号的反馈功率值。
反馈功率值能够反映出雾化腔的微波吸收效果,可以理解地,反馈功率值越小则代表雾化腔的微波吸收效果越强,反馈功率值越大则代表雾化腔的微波吸收效果越差。选择微波吸收效果最强的反馈功率值对应的微波频率作为目标微波频率。
在气溶胶产生装置出厂之前,对设定频率范围中的频率进行设置。其中,设定频率范围中的最大值为雾化腔中容置有气溶胶产生基质时,微波组件输出微波的最佳频率值。设定频率范围中的最小值为雾化腔处于空腔状态时,微波组件输出微波的最佳频率值。
在检测到目标微波频率小于设定频率范围中的最小值,则判定雾化腔当前处于空腔状态,即雾化腔内未容置有气溶胶产生基质,则控制微波组件停止运行,避免雾化腔干烧。
在检测到目标微波频率大于设定频率范围中的最大值,则判定雾化腔内容置有气溶胶产生基质。此时,控制微波组件按照扫频筛选得到的目标微波频率向雾化腔内馈入微波,提高了气溶胶产生基质对微波的吸收效率,提高了气溶胶产生基质的雾化效果。
在检测到目标微波频率小于设定频率范围的频率平均值,则判定雾化腔当前处于空腔状态,即雾化腔内未容置有气溶胶产生基质,则控制微波组件停止运行,避免雾化腔干烧。
在检测到目标微波频率大于设定频率范围中的频率平均值,则判定雾化腔内容置有气溶胶产生基质。此时,控制微波组件按照扫频筛选得到的目标微波频率向雾化腔内馈入微波,提高了气溶胶产生基质对微波的吸收效率,提高了气溶胶产生基质的雾化效果。
在检测到目标微波频率处于微波频率范围内,则进一步根据微波频率范围的平均值与目标微波频率的数值关系,对雾化腔内气溶胶产生基质的状态进行检测。避免检测误差导致误判,进一步提高了对雾化腔内是否存在气溶胶产生基质判断的准确性,避免误判造成的对空雾化腔进行微波加热的情况发生,保证气溶胶产生装置不会对空腔状态的雾化腔进行微波加热的同时,提高了用户 的使用体验。

实施例五:
如图10所示,本申请的第五个实施例中提供了一种气溶胶产生装置1000,包括:存储器1002,存储器1002中存储有程序或指令;处理器1004,处理器1004执行存储在存储器1002中的程序或指令以实现如上述实施例一中任一实施例中的气溶胶产生装置的控制方法的步骤。因而具有上述任一实施例中的气溶胶产生装置的控制方法的全部有益技术效果,在此不再做过多赘述。
本实施例提供的气溶胶产生装置1000还包括雾化腔和微波组件,雾化腔用于容置气溶胶产生基质,微波组件用于向雾化腔内馈入微波,微波作用于气溶胶产生基质,使气溶胶产生基质受热雾化。微波组件与处理器1004相连,处理器1004执行气溶胶产生装置的控制方法以对气溶胶产生装置1000中的微波组件进行控制。
实施例六:
如图11所示,本申请的第六个实施例中提供了一种气溶胶产生装置100,包括:壳体102、雾化腔103、微波组件104和控制装置105。
雾化腔103设置于壳体102内,雾化腔103用于容置气溶胶产生基质108;
微波组件104用于向雾化腔103内馈入微波;
控制装置105用于控制微波组件104在微波频率范围内扫频运行,查找微波频率范围中的目标微波频率;根据目标微波频率与设定频率范围的数值关系,确定雾化腔103内的气溶胶产生基质108的存在状态;根据气溶胶产生基质108的存在状态,控制微波组件104的运行状态。
本实施例气溶胶产生装置100包括壳体102、雾化腔103、微波组件104和控制装置105。壳体102内设置有雾化腔103,雾化腔103用于容置气溶胶产生基质108。微波组件104的输出端与雾化腔103相连通,微波组件104通电运行将微波馈入到雾化腔103内,气溶胶产生基质108在微波的作用下受热雾化。
控制装置105接收到开始雾化指令,控制微波组件104在微波频率范围内进行扫频运行。具体地,依次按照微波频率范围内的每个微波频率控制微波组件104向雾化腔103内馈入微波。根据雾化腔103内参数的变化从而确定微波频率范围中的目标微波频率,目标微波频率为当前雾化腔103状态下,微波组件104运行的最佳频率点,即雾化腔103内对微波吸收量最大的微波频率。根据目标微波频率与设定频率范围的数值关系,能够判断雾化腔103内气溶胶产生基质108的存在状态,即雾化腔103内是否容置有气溶胶产生基质108。再根据雾化腔103内气溶胶产生基质108的存在状态,对微波组件104的运行进行控制。如果检测到雾化腔103内容置有气溶胶产生基质108,则正常控制微波组件104运行,以对气溶胶产生基质108进行加热雾化,如果检测到雾化腔103为空腔状态,为避免向空腔内馈入微波导致气溶胶产生装置100使用寿命缩短,控制微波组件104停止运行。本申请通过微波组件104的扫频运行确定雾化腔103当前状态下的目标微波频率,从而对雾化腔103内气溶胶产生基质108是否在位进行检测,避免向空腔状态下的雾化腔103馈入微波,从而延长了气溶胶产生装置100的使用寿命。
可以理解的是,雾化腔103为空腔状态和雾化腔103内容置有气溶胶产生基质108的状态,通过扫频确定的目标微波频率相差较大,因而扫频得到的目标微波频率与设定频率范围的数值关系能够对雾化腔103内是否容置有气溶 胶产生基质108进行准确判断。
