Description

可控温的烘烤烟具 技术领域
本发明涉及烘烤烟具的技术领域，更具体的说，本发明涉及一种可控温的烘烤烟具。
 背景技术
烘烤烟具一般包括加热组件和电池组件，电池组件用于控制加热组件及提供电源给加热组件。加热组件包括加热元件，加热元件可将具有烟草的烟支进行烘烤发出烟雾，供使用者吸食。因烘烤发出的烟雾，相比烟草明火燃烧后产生的烟雾，减少了很多有害物质如焦油、一氧化碳、颗粒物等，因此使用烘烤烟具吸烟的方式受到人们的欢迎。
现有的烘烤烟具，用户打开启动开关后，加热元件发热升温至正常吸烟温度，但其后不管用户是否吸烟，其温度一直保持在吸烟状态的工作温度，电池功率损耗很大。另外在用户不吸烟时，烟支也一直处于烘烤状态，烟支内的烟草仍然处于损耗之中，导致烟支可真正被利用的时间缩短，而且烘烤时间长的同时烟雾不能被排出，再吸烟时，烟支内的烟草容易产生焦味、糊味，给用户造成不良的使用体验。

现有的重力传感器，是根据压电效应的原理来工作的，即利用其内部的由于加速度造成的晶体变形这个特性，由于晶体变形会产生电压，利用该电压和所施加的加速度之间的关系，就可以将加速度转化成电压输出，即设备移动的方式可转化为电压信号输出。本发明的重力传感器9，当其安装在烘烤烟具上发生移动时，根据其移动的方式，会产生不同的电信号。事先模拟人手吸烟的动作对烟具的三维坐标位置变化、移动速率进行检测可得到准备吸烟的标准手势信号。重力传感器9与手势信号处理单元61电连接，重力传感器9工作时，将检测信号发送给手势信号处理单元61，手势信号处理单元61根据检测所得的手势动作信号与设定的标准手势信号对比，即可判断出用户是否准备吸烟。当手势信号处理单元判断有准备吸烟的动作后，立即发出升温控制信号，调压单元71快速增加输出功率使加热元件R进行快速升温。
如图3所示，控制电路上还设有升压供电单元72，升压供电单元72与电池3及调压单元电71连接，升压供电单元72将电池的电压进行升压后输出给调压单元71。

如图1-图3所示的烘烤烟具，因其具备了上述元器件和电路结构，故在工作时，烘烤烟具1具备如下所述的功能：用户使用该烘烤烟具1时，首先按动启动开关K接通电池电源，控制电源单元73降压输出控制电压，给微控制器6和相关控制电路提供电源，通过微控制器6的控制，控制电源开关单元74给相关控制电路、检测单元和升压供电单元72接通电源，升压供电单元72将电压升高后输出电压给调压单元71，调压单元71根据微控制器6的指令进行升压或降压处理，最后输出不同电压给加热元件R。加热元件R工作后，温度上升到工作温度（例如230℃-270℃），此时提示单元51进行振动提示，用户根据提示单元51的振动提示，可以开始进行吸烟，计时单元62进行相关计时。
在设定的工作时间段内，阻值检测单元8工作时检测加热元件R的电阻阻值，由于用户吸烟时，加热元件3的电阻阻值会发生变化，微控制器6根据电阻阻值变化的信号就可以判断用户是否吸烟。微控制器6如果判断用户正在吸烟，调压单元71维持稳定的电压输出，使加热元件R的温度保持工作温度。如果用户在设定的工作时间段内没有吸烟，则微控制器6控制调压单元71降低电压输出，使加热元件R的加热温度降低到待机温度（例如100℃-150℃）并保持，以便节省电池的电能，同时使烤烟的可使用寿命延长。
降温后在设定的待机时间段内，重力传感器9工作时，模拟人手吸烟的动作对烟具的三维坐标位置变化、移动速率进行检测，并将检测信号发送给手势信号处理单元61，手势信号处理单元61预判用户是否准备吸烟。如果在设定的待机时间段内，重力传感器9检测到用户准备吸烟动作的手势信号，则手势信号处理单元61在检测到手势信号的瞬间即发出升温控制信号，微控制器6控制调压单元71迅速升高输出电压进行升温，等到用户将烟具的烟支放入口中吸烟时，加热元件R的加热温度已经迅速升高到工作温度并保持，这样用户可以立即进行吸烟。如果在设定的待机时间段内没有检测到吸烟动作的手势信号，则烟具进行自动关机。
本发明可调温的烘烤烟具，其优点在于，设有调压单元71、微控制器6、阻值检测单元8、重力传感器9和计时单元62等，阻值检测单元8可检测用户是否吸烟以便微控制器6判断是否需要降温，重力传感器9可检测吸烟的手势动作以便微控制器6判断是否需要提前升温，调压单元71可输出不同功率以便保持不同的加热温度。这样，使得用户在正常吸烟时，其加热温度可保持在工作温度的可吸烟状态，而通过阻值检测单元8检测到用户较长时间不吸烟时，可降低温度至待机温度而进入待机状态，待机时一旦通过重力传感器9检测到用户吸烟动作的手势信号后，又可迅速升温到吸烟所需的工作温度。这样，不仅可降低电池功率损耗，而且可减少烟草的损耗，延长烟支利用时间，避免烟草产生焦味或糊味，以及能快速吸出烟雾并增加每口的烟雾量，提升用户的使用体验。
