技术领域
本发明涉及烟具技术领域，特别是一种电子烟具及电子烟具的抽吸次数检测方法。
背景技术
传统的电子烟具的抽吸次数检测方法通常是在烟具的气流入口处设置一个咪头，通过咪头来检测抽吸时产生的负压来检测抽吸次数。但是采用咪头来检测抽吸时产生的负压时，需要有足够的气流量通过并产生较大的负压值才能够实现，适用于气流通过量较大的电子烟具。
然而，对于烘烤新型烟草的电子烟具来说，由于新型烟草和气流路径的结构的原因，抽吸时气流量较小，咪头一般很难感应到抽吸时产生的负压，容易导致抽吸次数检测不准确。
发明内容
基于此，有必要提供一种可以有效提高抽吸次数检测准确率的电子烟具及电子烟具的抽吸次数检测方法。

感温元件，所述感温元件包括感温端，所述感温端设置于所述气流通道内，当发生抽吸动作时，外部空气从所述进气口进入所述进气通道，并流入所述收容腔内，形成在所述气流通道内流动的气流，所述感温元件的感温端用于检测抽吸时与不抽吸时所述气流的温度以获知温度的变化，根据温度的变化获得抽吸次数；及
电路板，所述电路板与所述感温元件电连接，且所述电路板与所述烟具本体电连接。
上述电子烟具通电后，烟具本体内部产生热量，热量对烟具本体内部的空气进行加热。因为感温元件的感温端位于气流通道内，因此烟具本体内部产生的热量会辐射至感温元件的感温端。当发生抽吸动作时，外部空气从进气口进入进气通道，并流入收容腔内，形成在气流通道内流动的气流，因此抽吸和不抽吸时，感温端检测到的温度值不同以获知温度的变化，电路板根据温度的变化获得抽吸次数，因此无需通过感应负压，只需通过感温线的感温端检测温度变化即可获得抽吸次数，因此可以有效提高抽吸次数检测准确率。
一种电子烟具的抽吸次数检测方法，包括：
对烟具本体通电，以对所述烟具本体内的空气进行预热，直至所述烟具本体内的温度达到预设的温度值；
不抽吸时，感温元件的感温端检测到的温度值为第一温度值；
当发生抽吸动作时，外部空气通过进气口经由进气通道进入筒体内，并形成在气流通道内流动的气流，气流流过感温元件的感温端时，感温端检测到的温度值为第二温度值，所述第二温度值与所述第一温度值之间存在温度差；
电路板接收由所述感温元件检测到的第一温度值与第二温度值之间产生的温度差并转化成电感信号，通过检测电感信号以获得抽吸次数。
上述电子烟具的抽吸次数检测方法中，对烟具本体通电后，以对烟具本 体内的空气进行预热，直至烟具本体内的温度达到预设的温度值。不抽吸时，感温元件的感温端检测到的温度值为第一温度值。当发生抽吸动作时，外部空气通过进气口经由进气通道进入筒体内，并形成在气流通道内流动的气流，气流流过感温元件的感温端时，感温端检测到的温度值为第二温度值，第二温度值与第一温度值之间存在温度差。电路板接收由所述感温元件检测到的第一温度值与第二温度值之间产生的温度差并转化成电感信号，通过检测电感信号以获得抽吸次数，因此无需通过感应负压，只需通过感温线的感温端检测温度变化即可获得抽吸次数，因此可以有效提高抽吸次数检测准确率。

请参阅图1及图2，第一实施方式中的电子烟具100包括烟具本体110、感温元件120及电路板130。烟具本体110与感温元件120分别与电路板130电连接。
具体到第一实施方式中，烟具本体110包括筒体111、加热组件112、滤网113及套筒114。筒体111具有收容腔111a，筒体111被滤网113分隔成第 一筒体1111及第二筒体1112。即，滤网113将收容腔111a分隔成上下两个相连通的腔体，第一筒体1111内形成的为下腔体，第二筒体1112内形成的为上腔体。加热组件112设置于第一筒体1111内，第二筒体1112用于放置烟草制品。滤网113主要用于过滤置于第二筒体1112内的烟草制品产生的碎屑等等，防止碎屑掉入加热组件112上。
加热组件112与电路板130电连接，具体地，加热组件112通过导电线115与电路板130电连接。加热组件112通电后产生热量，热量用于对烟具本体110内的空气进行加热。筒体可以为具有加热功能的加热筒，此时加热筒与加热组件共同产生热量对烟草制品进行加热烘烤。当然，在其它的实施方式中，筒体也可以不具有加热功能，但具有导热功能。
套筒114套设于筒体111外，套筒114的内壁与筒体111的外壁之间形成进气通道111b，进气通道111b具有进气口111c。进气通道111b与收容腔111a相连通以形成气流通道。抽吸时，外界的冷空气在抽吸力的作用下通过进气口111c进入进气通道111b，并进入收容腔111a内，形成在气流通道内流动的气流(如图2中的虚线箭头方向)。
具体到第一实施方式中，加热组件112包括导热棒及加热丝，加热丝缠绕于导热棒上，加热丝的两端分别与电路板130电连接。筒体111可以由绝缘、易导热的材料制成，此时筒体111主要传导加热丝产生的热量。例如，筒体111可以是易导热金属、陶瓷或者其它介质，筒体111也可以是绝缘处理后的薄铝材质等等。电路板130可以为PCBA(printed circuit board assembly，装配印刷电路板)板。
滤网113的材质可以为易导热和易清洁的材料，例如金属、不锈钢等等。通过导热棒与滤网113紧密贴合，加热丝产生的热量可以通过导热棒迅速传导至滤网113上，而滤网113与烟草制品直接接触，因此滤网113可对烟草制品加热，提高加热效率。
还可以在导热棒的外侧壁上开设螺旋槽，螺旋槽沿着导热棒的轴向延伸，加热丝沿着螺旋槽呈螺旋状缠绕于导热棒上，加热丝、导热棒的外侧壁、螺 旋槽的侧壁与筒体111的内侧壁共同围成导流通道。螺旋槽的侧壁的高度大于加热丝的直径尺寸，以保证导流通道的尺寸。
因为加热丝沿螺旋槽呈螺旋状缠绕于导热棒的外侧壁，因此不仅通过加热丝直接对气流进行加热，加热丝产生的热量还可以使导热棒升温，导热棒升温后也可以对气流进行加热。加热丝通过导线与电路板130电连接。
当然，在其它的实施方式中，加热方式还可以为电感加热的方式。对应地，加热组件为电感加热的结构。
感温元件120包括感温端121，感温端121设置于气流通道内，且感温元件120与电路板130电连接。感温元件120可以为感温线、NTC(Negative Temperature Coefficient，负温度系数热敏电阻器)或者热电偶。可以在套筒114的侧壁上开孔，感温元件120的感温端121通过开孔伸入气流通道内，然后将开孔密封。
当发生抽吸动作时，外部空气从进气口111c进入进气通道111b，并流入收容腔111a内，形成在气流通道内流动的气流。感温元件120的感温端121用于检测抽吸时与不抽吸时气流通道内的温度以获知温度的变化，根据温度的变化获得抽吸次数。
具体到第一实施方式中，感温元件120的感温端121位于靠近气源处，使检测到的温度差较大，以提高检测抽吸次数的准确性。具体地，感温元件120的感温端121位于进气通道111b内，且靠近所述进气口111c。
上述第一实施方式中的电子烟具100通电后，加热组件112产生热量，热量对烟具本体110内部的空气进行预加热。因为感温元件120的感温端121位于进气通道111b内，因此加热组件112产生的热量会辐射至感温元件120的感温端121。不抽吸时，感温元件120检测到的经过预热后的温度为第一温度值，此时感温元件120检测到的温度较外界空气的温度高。
当发生抽吸动作时，外部空气从进气口111c进入进气通道111b，并流入收容腔111a内，形成在气流通道内流动的气流。因为感温元件120靠近进气口111c，此时感温元件120检测到的温度值为第二温度值，第二温度值与外 界进入的冷空气的温度值相当，第二温度值较第一温度值低。因此抽吸和不抽吸时，感温端121检测到的温度值不同以获知温度的变化，电路板130根据温度的变化获得抽吸次数，因此无需通过感应负压，只需通过感温线的感温端121检测温度变化即可获得抽吸次数，因此可以有效提高抽吸次数检测准确率。
当然，请参阅图3及图4，在第二实施方式中，感温元件120的感温端121位于靠近加热源处。具体地，感温元件120的感温端121位于筒体111内，且位于第二筒体1112靠近加热组件112处。具体地，滤网113的数量为两个，两个滤网113间隔设置，分别为第一滤网1131及第二滤网1132，第一滤网1131与加热组件112直接接触，第二滤网1132位于第二筒体1112内。感温元件120的感温端121位于第一滤网1131与第二滤网1132之间。
当然，在其它的实施方式中，滤网113的数量还可以仅为一个，感温元件120的感温端121直接位于第二筒体1112内且靠近加热组件112处即可。
上述第二实施方式中的电子烟具100通电后，加热组件112产生热量，热量对烟具本体110内部的空气进行预加热。因为感温元件120的感温端121位于筒体111内，且位于第一滤网1131与第二滤网1132之间，因此加热组件112产生的热量会辐射至感温元件120的感温端121。不抽吸时，感温元件120检测到的经过预热后的温度为第一温度值，此时感温元件120检测到的温度比加热组件112的温度低。
当发生抽吸动作时，外部空气从进气口111c进入进气通道111b，并流入收容腔111a内，形成在气流通道内流动的气流。因为感温元件120位于第二筒体1112内靠近加热组件112处，此时感温元件120检测到的温度值为第二温度值，第二温度值与从第一筒体1111内空气的温度值相当，第二温度值较第一温度值高。因此抽吸和不抽吸时，感温端121检测到的温度值不同以获知温度的变化，电路板130根据温度的变化获得抽吸次数，因此无需通过感应负压，只需通过感温线的感温端121检测温度变化即可获得抽吸次数，因此可以有效提高抽吸次数检测准确率。

套管213套设于筒体211外，进气通道214位于筒体211设置有加热组件212的一端。即，进气通道214位于筒体211的底端。进气通道214具有进气口214a，进气通道214与收容腔211a相连通形成气流通道。抽吸时，外界的冷空气在在抽吸力的作用下通过进气口214a进入进气通道214内，并进入收容腔211a内，形成在气流通道内流动的气流(如图6中的箭头方向所示)。
具体到第三实施方式中，加热组件212包括导热棒及加热丝，加热丝缠绕于导热棒上，加热丝的两端分别与电路板230电连接。筒体211可以由绝缘、易导热的材料制成，此时筒体211主要传导加热丝产生的热量。例如，筒体211可以是易导热金属、陶瓷或者其它介质，筒体211也可以是绝缘处理后的薄铝材质等等。电路板230可以为PCBA(printed circuit board assembly，装配印刷电路板)板。
还可以在导热棒的外侧壁上开设螺旋槽，螺旋槽沿着导热棒的轴向延伸，加热丝沿着螺旋槽呈螺旋状缠绕于导热棒上，加热丝、导热棒的外侧壁、螺旋槽的侧壁与筒体211的内侧壁共同围成导流通道。螺旋槽的侧壁的高度大于加热丝的直径尺寸，以保证导流通道的尺寸。
因为加热丝沿螺旋槽呈螺旋状缠绕于导热棒的外侧壁，因此不仅通过加热丝直接对气流进行加热，加热丝产生的热量还可以使导热棒升温，导热棒升温后也可以对气流进行加热。加热丝通过导线与电路板230电连接。

具体地，通孔530a开设于第一通道531的侧壁上，感温元件540的感温端541通过通孔530a伸入第一通道531内。因此，感温端541距离加热组件520的距离较近，不抽吸时，加热组件520辐射至感温端541的热量较多，感温端541检测到的第一温度值较大。感温元件540的感温端541通过通孔530a伸入第一通道531后，用密封胶将通孔530a密封，防止漏气。

上述电子烟具500通电后，加热组件520产生热量，热量对加热组件520周围的空气进行加热。因为感温元件540的感温端541伸入加热套512内，且位于靠近加热组件520的端部处，因此加热组件520通电产生的热量会辐射至感温元件540的感温端541。开始抽吸时，感温端541检测到的温度值 为第一温度值。
抽吸时，抽吸力使气流通道内形成流动的气流，被加热组件520加热的空气向上流动。停止抽吸时，经过感温元件540的感温端541的气流温度会升高，感温端541检测到升高后的温度值为第二温度值，第二温度值与第一温度值之间存在温度差，电路板550接收温度差并转化成电感信号，通过检测电感信号获得抽吸次数，因此无需通过感应负压，只需通过感温元件540的感温端541检测温度变化即可获得抽吸次数，因此可以有效提高抽吸次数检测准确率。

筒体610具有收容腔610a，收容腔610a用于收容烟草制品。筒体610通电后产生热量，产生的热量直接对烟草制品烘烤加热。因此筒体610为加热筒。例如，筒体610可以为耐高温、易导热的材料制成。筒体610通过导线611与电路板640电连接。
进气通道620的一端套设于筒体610的一端，且进气通道620与收容腔610a相连通以形成气流通道，进气通道620的侧壁开设有通孔620a。
感温元件630包括感温端631，感温端631通过通孔620a伸入进气通道620内，且位于靠近筒体610处。电路板640与筒体610电连接，且电路板640与感温元件630的另一端电连接。
具体到第九实施方式中，进气通道620包括第一通道621及第二通道622，第一通道621与第二通道622呈预设角度设置。例如，第一通道621与第二通道622呈锐角设置。当然，在其它的实施方式中，第一通道621也可以与第二通道622垂直设置。第一通道621套设于筒体610的一端，第二通道622的一端设置于第一通道621的另一端且与第一通道621相连通。通孔620a开设于第一通道621的侧壁上，感温元件630的感温端631通过通孔620a伸入第一通道621内。因此感温元件630的感温端631距离筒体610的端部较近， 筒体610通电后产生的热量会辐射至感温端631。
当然，请参阅图16，第十实施方式中的电子烟具600中，进气通道620包括第一通道621及第二通道622，第一通道621与第二通道622呈预设角度设置。例如，第一通道621与第二通道622呈锐角设置。当然，在其它的实施方式中，第一通道621也可以与第二通道622垂直设置。第一通道621套设于筒体610的一端，第二通道622的一端设置于第一通道621的另一端且与第一通道621相连通。通孔620a开设于第二通道622的侧壁上，感温元件630的感温端631通过通孔620a伸入第二通道622内。因此感温元件630的感温端631距离筒体610的端部较第九实施方式的远。
上述电子烟具600通电后，筒体610产生热量，热量直接传导至烟草制品。因为感温元件630的感温端631伸入进气通道620内，且位于靠近筒体610的端部处，因此筒体610通电产生的热量会辐射至感温元件630的感温端631。开始抽吸时，感温端631检测到的温度值为第一温度值。
抽吸时，抽吸力使气流通道内形成流动的气流，冷空气从进气通道620进入。停止抽吸时，经过感温元件630的感温端631的气流温度会降低，感温端631检测到降低后的温度值为第二温度值，第二温度值与第一温度值之间存在温度差，电路板640接收温度差并转化成电感信号，通过检测电感信号获得抽吸次数，因此无需通过感应负压，只需通过感温元件630的感温端631检测温度变化即可获得抽吸次数，因此可以有效提高抽吸次数检测准确率。
请参阅图17，还提供一种电子烟具100的抽吸次数检测方法，具体包括以下步骤：
步骤S110，对烟具本体110通电，以对烟具本体110内的空气进行预加热，直至烟具本体110内的温度导到预设的温度值。
该预设的温度值可以为一个合理的温度范围值，而不仅限于一个或者多个点值。在其中一个实施方式中，对烟具本体110通电具体为对加热组件112进行通电，加热组件112通电后产生热量，热量对加热组件112周围的空气 进行预热。在另外一个实施方式中，对烟具本体110通电具体为对筒体310通电筒体310作为加热筒，加热筒通电后直接对收容腔内盛放的烟草制品进行传导式加热。
步骤S120，不抽吸时，感温元件的感温端检测到的温度值为第一温度值。
步骤S130，当发生抽吸动作时，外部空气通过进气口111c经由进气通道111b进入筒体111内，并形成在气流通道内流动的气流，气流流过感温元件的感温端时，感温端检测到的温度值为第二温度值，第二温度值与第一温度值之间存在温度差。
具体地，第一温度值可以高于第二温度值。此时，感温元件120的感温端121位于靠近气源处。当然，在其它的实施方式中，第一温度值可以低于第二温度值，此时，感温元件120的感温端121位于靠近热源处。
步骤S140，电路板130接收由感温元件120检测到的第一温度值与第二温度值之间产生的温度差并转化成电感信号，通过检查电感信号以获得抽吸次数。以此循环，不抽吸时和抽吸时检测到的温度值不同，由此来确定抽吸次数。
上述电子烟具100的抽吸次数检测方法中，对烟具本体110通电后，以对烟具本体110内的空气进行预热，直至烟具本体110内的温度达到预设的温度值。不抽吸时，感温元件120的感温端121检测到的温度值为第一温度值。当发生抽吸动作时，外部空气通过进气口111c经由进气通道111b进入筒体111内，并形成在气流通道111b内流动的气流，气流流过感温元件120的感温端121时，感温端121检测到的温度值为第二温度值，第二温度值与第一温度值之间存在温度差。电路板130接收由所述感温元件120检测到的第一温度值与第二温度值之间产生的温度差并转化成电感信号，通过检测电感信号以获得抽吸次数，因此无需通过感应负压，只需通过感温线的感温端检测温度变化即可获得抽吸次数，因此可以有效提高抽吸次数检测准确率。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本 领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
