具体实施方式
本发明提供一种 智能奶瓶套 ，为使本发明的目的、技术方案及效果更加清楚、明确，以下参照附图并举实例对本发明进一步详细说明。 应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明 。
请参阅图1、并结合图2所示，本发明提供的智能奶瓶套包括用于夹持奶瓶的第一弹性夹紧瓣1和第二弹性夹紧瓣6，所述第一弹性夹紧瓣1和所述第二弹性夹紧瓣6之间形成用于放置奶瓶的放置空间。使用时可将奶瓶放入所述放置空间中，喂养婴儿或婴儿自行饮食时可拿起奶瓶套直接饮用。当然的，由于奶瓶表面多为光滑面，可将所述第一弹性夹紧瓣1和所述第二弹性夹紧瓣6均设计为硅胶弹性夹紧瓣，以起到对奶瓶的夹持作用；所述第一弹性夹紧瓣1和所述第二弹性夹紧瓣6 中，至少有一个弹性夹紧瓣的底部与底座5侧边的连接处具有弹性，以便于奶瓶的放入和取出。进一步地，可在 所述第一弹性夹紧瓣1和所述第二弹性夹紧瓣6内均设置防滑垫7，用于在奶瓶倾斜时对奶瓶进行防滑处理。
具体的，所述智能奶瓶套还包括与所述第一弹性夹紧瓣1一体设置的底座5，将底座5和第一弹性夹紧瓣1一体设置能够使各测量装置处于一个相对密封的空间中，使测量环境不受外界环境影响，能够保证测量数据的准确性。所述底座5内设有PCB板44，所述PCB板44上分别设有用于检测奶瓶温度的测温装置3和用于检测奶瓶内液体浓度的浓度检测装置4，所述PCB板44下方设有与所述PCB板44连接的用于测量奶瓶重量的称重装置10，所述PCB板44还与设置在所述第一弹性夹紧瓣1上的显示装置2连接。即所述PCB板44分别与所述测温装置3、浓度检测装置4和称重装置10连接，并接收、处理所述测温装置3、浓度检测装置4和称重装置10检测的数据；然后将处理后的数据输出至与所述PCB板44连接的显示装置2，显示装置2显示各装置的检测数据，并与用户读取、参阅对比，使用户更科学的喂养婴儿。
进一步地，如图3所示，上述测温装置3包括红外热电堆传感器41，为保证所述红外热电堆传感器41能够快速、准确的检测放置在智能奶瓶套中的奶瓶温度，可设置的、一个 套设在所述 红外热电堆传感器41外部的铜套42，所述铜套42 使被测物体（奶瓶）的热量可以通过该铜套42迅速的传导到红外热电堆传感器41上，缩短了测温时间，还隔绝了外部环境（其他红外线）的干扰和影响，同时，由于测温时间短，也减小了红外热电堆传感器41自身热辐射和外界环境对测温的影响，提高了测温的准确度。还可增设的、一个 设置在所述铜套42上的用于将奶瓶散发的红外线聚焦至红外热电堆传感器41的所述 菲涅尔透镜，所述菲涅尔透镜是奶瓶辐射的红外线聚焦到 红外热电堆传感器41上，进一步提高了测温的准确性。
具体的， 所述铜套42为圆台形的空心铜套42 所述 铜套42 的顶部和底部均开有圆口，所述 铜套42 底部开圆口用于放置红外热电堆传感器41，所述 铜套42 顶部开圆口有利于将被测物体辐射的红外线导入到红外热电堆传感器41上。所述铜套42呈喇叭状，铜套42的顶部面积大于底部面积。所述 铜套42 采用黄铜材质，其自身由于材质原因，不产生红外线，避免了 铜套42 自身干扰红外热电堆传感器41，提高了红外热电堆传感器41测温的准确性。优选的，所述铜套42的顶端的内径为11.5mm，所述铜套42的底部的内径为5.5mm，所述铜套42的壁厚为0.5mm。
进一步地，所述红外热电堆传感器41四周设有用于增加空气对流的导流槽43。优选的，可在 所述PCB板44上的导流槽43有四个，对称设置在所述红外热电堆传感器41的四周，可隔绝PCB板44上其他元件对红外热电堆传感器41的影响 ，提高了测温的准确度。 所述导流槽43为'L形'，可最大限度的增加PCB板44的空气对流。
上述的智能奶瓶套中，结合图1和图2所示，所述浓度检测装置4包括用于区分奶和水、检测液体浓度的浑浊度传感器，当奶瓶中的奶的浓度增加时，液体中红外反射颗粒数量增多，红外反射的量也会线性增加，采用浑浊度传感器能够解决奶粉或其他溶解质在奶瓶中水中的溶解度，方便用户了解喂养数据。为增加所述浑浊度传感器的检测准确性，可所述浑浊度传感器上设置一红外过滤片或菲涅尔透镜，过滤掉环境光干扰。具体的，可先通过实验对不同浓度的奶的红外反射特性进行定标，在实际测量中会依据实验数据中奶的浓度与红外反射量的对应关系计算出当前液体浓度。
上述智能奶瓶套中，如图2所示，所述称重装置10包括用于测量奶瓶重量的电阻应变式称重传感器（图中未示出）和用于检测智能奶瓶套使用状态的三轴重力传感器（图中未示出）。其中电阻应变式称重传感器可检测奶瓶及奶瓶内液体的重量，方便用户把握具体喂养婴儿的奶量，避免因过度喂养使婴儿产生不适。当智能奶瓶套被使用时，三轴重力传感器会检测智能奶瓶套的倾斜方向从而判断智能奶瓶套是被正在使用还是静置；三轴重力传感器检测数据可通过蓝牙装置或WIFI装置发送至用户或喂养人的移动终端，可实时监控婴儿是否在自行饮用，方便用户对婴儿的监控和喂养。
进一步地，如图1和图2所示，在智能奶瓶套的一个具体实施例中，所述显示装置2为E-link显示屏。E-ink显示屏具有耗电率低和刷新速度较慢的特点，因为婴儿的眼睛还未发育完全，E-ink显示屏刷新速度慢，E-ink屏幕不闪烁，看起来就像纸张上的墨水，让人阅读时完全不刺眼，有利于保护婴儿视力。而且E-ink还具有掉电时，能显示掉电前的数据。这使得智能奶瓶套在使用时没电了，当时的奶瓶内奶的浓度还是可以供用户参考。
更进一步地，在本发明的一个具体实施例中，所述智能奶瓶套还包括一芯片装置（图中未示出），所述芯片装置由处理器装置和蓝牙装置组成，当然的也可以设置一个WIFI装置。用户可将移动终端通过蓝牙装置和/或WIFI装置连接所述智能奶瓶套。例如，用户可将手机与所述智能奶瓶套连接，进行实时监控奶瓶数据或智能奶瓶套，如果奶瓶内的奶温度过高、奶浓度过低，用户可将奶瓶静置待奶瓶温度适中后喂养婴儿或添加奶量增加奶浓度后喂养婴儿，避免了因奶温度过高烫伤婴儿或奶浓度过低婴儿不能吃饱的问题。同时还可是通过称重装置10监控智能奶瓶套的使用状态和喂养量，如果婴儿自行饮用奶时，可通过称重装置10称量一定量的奶给与婴儿，防止婴儿饮食过多等。
另外，如图2所示，所述的智能奶瓶套中，所述底座5底部还设有用于密封的密封件9，设置于所述密封件9内圈中的支撑座8。所述密封件9能够防止外界温度或光环境温度测量和奶浓度测量产生影响，设置于所述密封件9内圈中的支撑座8则用于支撑所述智能奶瓶套，支撑座8和所述密封件9结合使用可防止智能奶瓶受到强力冲撞发生损坏。进一步地，可在所述底座5底部设置一防水密封件将所述PVB板44包裹起来，使所述智能奶瓶套具有防水性能。使所述智能奶瓶套整体具有防水性能需要考虑的是所述显示装置2的防水性，可将显示装置2的LCD部分用胶把显示屏和所述第一夹紧弹性瓣1粘结，以使所述智能奶瓶套整体具有防水功能，防止因使用不当掉入水中损坏。
综上所述，本发明所提供的智能奶瓶套，由于采用了与所述第一弹性夹紧瓣1一体设置的底座5，所述底座5内设有PCB板44，所述PCB板44上分别设有用于检测奶瓶温度的测温装置3和用于检测奶瓶内液体浓度的浓度检测装置4，所述PCB板44下方设有与所述PCB板44连接的用于测量奶瓶重量的称重装置10，能够检测奶瓶中奶的温度、液体浓度和重量，在喂养婴儿时能够对应喂养标准喂养婴儿，方便婴儿的喂养和安全喂养，使奶瓶套实现了智能化。

请一并参阅图4、图5和图8，其中，图8为本发明智能奶瓶套的控制电路中显示模块400的电路图。本发明的智能奶瓶套的控制电路中，所述显示模块400包括：电子纸显示屏、显示屏连接器J1、第十二电容C12、第十三电容C13、第十四电容C14、第十五电容C15、第十六电容C16、第十七电容C17、第十八电容C18、第十九电容C19、第二十电容C20、第二十一电容C21、第二十二电容C22、第二十三电容C23、第二十四电容C24、第三电阻R3、第四电阻R4、第五电阻R5、第一压敏电阻Rnc1、MOS管Q1、第一二极管D1、第二二极管D2、第三二极管D3和第六电感L6。
电子纸显示屏与显示屏连接器J1插接，用于显示智能奶瓶套中放置的奶瓶的奶量、重量、温度以及奶消耗量等信息。所述电子纸显示屏具有轻薄、省电的特点，无需背光，不会对婴幼儿的眼睛造成刺激，而且电子纸显示屏耗电量极少，电子纸显示屏不刷新界面时几乎不耗电，而且，基于电子纸显示屏采用的电子墨水技术，即使断电，电子纸显示屏的画面也不会消失，而是停留在断电时的画面，有效的保护了智能奶瓶套的信息，而且断电后无需重启硬件系统大幅降低了智能奶瓶套硬件系统的功耗。
