附图说明
图1是本发明实施例气流加热装置的示意图。
图2是图1所示的气流加热装置中加热控制方法的流程图。
具体实施方式
以下通过具体而非限定的实施例对本发明加以详述，以使本发明的优点和特征能更易于被本领域技术人员理解。
如图1所示，本发明实施例气流加热装置，包括气道外管1以及设置于气道外管1中的气道内支架2，气道内支架2包括中心柱21以及沿中心柱21设置的螺旋式导流叶22，中心柱21、导流叶22与气道外管1之间形成螺旋形气道，供气流3(图1中虚线箭头所示)通过。螺旋式导流叶22使气流3在通过时呈螺旋形流动，相对直线通过方式，加热更加充分，热交换效率高。根据需要，在其它实施例中，螺旋式导流叶22可以不设置于中心柱21上，而设置在气道外管1内侧。还可以不采用螺旋形气道，而采用直线形或其它方式。
在加热件的周侧设有第一温度传感元件4，在位于气道进气口位置设有气流传感元件7，第一温度传感元件4用以检测加热件的第一温度，气流传感元件7用以检测抽吸信号，也即是否有气流流动，来判断用户是否开始抽吸。在其它实施例中，也可不设气流传感元件7，而通过诸如用户打开开关，或检测用户嘴唇接触烟嘴等其它方式，来判断用户是否开始抽吸。图1仅以第一温度传感元件4设置在气道进气口为例，实际实现时，第一温度传感元件4仅需能够测量加热件的温度即可，其还可以设置在加热件表面的任一位置处，对此并不做限定。 本实施例所说的第一温度传感元件4或者第二温度传感元件5均可以为温度传感器。
在位于气道出气口位置设有第二温度传感元件5，用以检测出气口处气体的第二温度，第二温度即为加热后气流的温度，也就是烟草加热温度。根据需要，还可在气道外管1装设加热件第三温度传感元件6，以检测加热件的温度，当加热件的温度达到预设阈值时，停止加热，避免由于加热件的温度过高而发生危险。可选地，本实施例所说的出气口位置是指与气道出气口之间的距离小于预设数值的位置。
气道外管1的内壁可环绕设置有一加热件，气道内支架2上也可沿导流叶22环绕设置加热件(图中未示)，两加热件可共同加热，也可仅加热其中一个，通过不同情形下选择共同加热或加热一个，可节省电能。本实施例所说的加热件可以是发热电阻，对此并不做限定。
本发明实施例气流加热装置还设有一控制装置(图中未示)，其连接第一温度传感元件4、第二温度传感元件7与加热件，以接收第一温度传感元件4、第二温度传感元件5检测到的温度信息，控制加热件。
在其它实施例中，还提供一种电子烟，包括如上所述的气流加热装置。
如图2所示，本发明实施例气流加热控制方法，用于如上所述的气流加热装置，包括如下步骤S10与S20。
S10、获取第一温度传感元件和第二温度传感元件检测到的温度信息。其中，第一温度传感元件用于检测加热件的温度，第二温度传感元件位于气道出气口位置用于检测气道出气口气体的温度。
S20、根据温度信息对加热件进行控制。
其中，S20根据温度信息对加热件进行控制可以包括如下步骤S21－S24。
S21、在接收到点烟信号时，控制加热件进入加热模式。
可选地，本步骤可包括：控制加热件以较高的第三功率进行加热。第三功率可以为电子烟中系统默认的功率，也可以为用户自主设置的功率。并且，用户在设置功率时，可以通过电子烟中的触摸屏设置，也可以通过电子烟中的实体按键设置，在此不再赘述。
可选地，在加热件包括至少两个时，本步骤还可以包括：控制全部加热件进行加热。
S22、判断第一温度传感元件检测到的第一温度是否达到第一设定温度。
第一设定温度可以为电子烟系统默认的温度，也可以为用户自主设置的温度。
S23、当第一温度传感元件检测到的第一温度达到第一设定温度时，控制加热件进入保温模式，并发出提示信息。
在检测得到的第一温度达到第一设定温度时，说明此时气道进气口处的温度已经升到所需的温度，此时电子烟即可控制加热件进入保温模式，并发出提示信息。其中，控制加热件 进入保温模式可包括：控制加热件以较低的第四功率进行加热，或/和控制部分加热件进行加热；其中，第四功率小于第三功率。这样能降低加热功率，节省电能。
与上述步骤类似，第四功率也可以为电子烟中系统默认的功率，或者是用户设置的功率。
另外，上述所说的提示信息用于提示用户开始抽吸。实际实现时，提示信息可以为一段音频，也可以为震动、响铃，当然还可以通过灯光闪烁来实现。
实际实现时，若检测到的第一温度未达到第一设定温度，则为了使得进气口处的温度达到所需的温度，电子烟继续控制加热件处于加热模式。
S24、当检测到抽吸信号时，根据第二温度传感元件检测到的第二温度来控制加热件加热。
本步骤可包括：若第二温度低于第二设定温度，则说明出气口的温度还未达到所需的温度，此时控制加热件以第一功率进行加热，直到检测到的第二温度达到第二设定温度；若第二温度等于或大于第二设定温度，则说明出气口的温度已经达到所需的温度此时可以控制加热件以第二功率进行加热；其中，第一功率大于第二功率。通过上述对功率的调整，既能快速加热使第二温度达到设定温度，又能在达到后以较低功率保温，节省电能，降低能耗。
在上述实施例中，用户开始抽吸也即电子烟中的雾化组件开始雾化之后，电子烟可以记录第一温度传感元件和第二温度传感元件检测得到的温度、加热件的功率和加热件的电压或者加热件的电流中的至少一种，进而根据历史统计得到的上述数据训练一套规则用于在用户抽吸之前，将温度保持在第一设定温度，并在用户开始抽吸之后，将气道出气口的温度保持在第二设定温度。
实际实现时，上述加热控制方法还可以包括：获取加热件的第三温度，检测第三温度是否达到第三设定温度，若达到第三设定温度，则停止加热件加热。通过在加热件温度较高时，停止加热，避免了由于温度过高而导致的安全隐患。当然，本实施例仅以在达到第三设定温度时，控制加热件停止加热来举例说明，实际实现时，还可以控制加热件以第五功率加热，第五功率小于第三功率，或者小于第一功率，在此不再赘述。
本申请实施例还提供了一种电子烟，所述电子烟包括存储器和处理器；
所述存储器中存储有至少一条程序指令；
所述处理器通过加载并执行所述至少一条程序指令以实现如下方法：
获取第一温度传感元件和第二温度传感元件检测到的温度信息；
根据所述温度信息对加热件进行控制；
其中，所述第一温度传感元件用于检测加热件的温度，所述第二温度传感元件位于所述 气道出气口位置用于检测所述气道出气口气体的温度，所述加热件用于加热所述气道中的空气。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
