具体实施方式
在下文的描述中，给出了大量具体的细节以便提供对本申请更为彻底的理解。然而，对于本领域技术人员而言显而易见的是，本申请可以无需一个或多个这些细节而得以实施。在其他的例子中，为了避免与本申请发生混淆，对于本领域公知的一些技术特征未进行描述。
应当理解的是，本申请能够以不同形式实施，而不应当解释为局限于这里提出的实施例。相反地，提供这些实施例将使公开彻底和完全，并且将本申请的范围完全地传递给本领域技术人员。在附图中，为了清楚，层和区的尺寸以及相对尺寸可能被夸大。自始至终相同附图标记表示相同的元件。
应当明白，当元件或层被称为“在...上”、“与...相邻”、“连接到”或“耦合到”其它元件或层时，其可以直接地在其它元件或层上、与之相邻、连接或耦合到其它元件或层，或者可以存在居间的元件或层。相反，当元件被称为“直接在...上”、“与...直接相邻”、“直接连接到”或“直接耦合到”其它元件或层时，则不存在居间的元件或层。应当明白，尽管可使用术语第一、第二、第三等描述各种元件、部件、区、层和/或部分，这些元件、部件、区、层和/或部分不应当被这些术语限制。这些术语仅仅用来区分一个元 件、部件、区、层或部分与另一个元件、部件、区、层或部分。因此，在不脱离本申请教导之下，下面讨论的第一元件、部件、区、层或部分可表示为第二元件、部件、区、层或部分。
空间关系术语例如“在...下”、“在...下面”、“下面的”、“在...之下”、“在...之上”、“上面的”等，在这里可为了方便描述而被使用从而描述图中所示的一个元件或特征与其它元件或特征的关系。应当明白，除了图中所示的取向以外，空间关系术语意图还包括使用和操作中的器件的不同取向。例如，如果附图中的器件翻转，然后，描述为“在其它元件下面”或“在其之下”或“在其下”元件或特征将取向为在其它元件或特征“上”。因此，示例性术语“在...下面”和“在...下”可包括上和下两个取向。器件可以另外地取向(旋转90度或其它取向)并且在此使用的空间描述语相应地被解释。
为了彻底理解本申请，将在下列的描述中提出详细的结构，以便阐释本申请提出的技术方案。本申请的较佳实施例详细描述如下，然而除了这些详细描述外，本申请还可以具有其他实施方式。
如图1所示，常见的吸奶器在采取TOF测距组件检测奶瓶中奶量的过程中，TOF发射端121发射出检测光线，奶瓶盖110上设有红外透光板130，TOF发射端121发射出的检测光线依次穿过红外透光板130和奶瓶盖110，然后识别到奶瓶中奶液的液面，之后测距光线再依次穿过奶瓶盖110和红外透光板130反射回到TOF接收端122。当检测光线穿过红外透光板130和奶瓶盖110时，如果奶瓶盖110上面轻微沾奶或者有水蒸气干扰，检测光线会在红外透光板130与奶瓶盖110内部发生折射，经过不断折射后，检测光线传输到TOF接收端122，进而对奶瓶中液面距离的识别产生干扰，影响奶量识别的准确度。
为了解决对奶瓶中的奶量识别不准确的问题，本申请提供一种吸奶器，包括：奶瓶组件，其包括奶瓶和奶瓶盖，所述奶瓶盖能够封盖所述奶瓶的瓶口，所述奶瓶盖包括第一透光件和进液口，所述进液口设置于所述第一透光件内；主机，所述主机包括用于检测所述奶瓶内奶量的奶量检测组件，所述奶量检测组件包括具有发射端和接收端的测距组件，所述发射端用于发射光线，所述接收端用于接收所述光线的回光；第二透光件，位于所述测距组件和所述奶瓶盖之间；隔光件，包括第一隔光件和第二隔光件；所述第一隔光件设置于所述第一透光件内并贯穿所述第一透光件，用于至少部分阻隔所述 发射端所发射的光线经所述第一透光件折射后进入所述接收端；所述第二隔光件设置于所述第二透光件内并贯穿所述第二透光件，用于至少部分阻隔所述发射端所发射的光线经所述第二透光件折射后进入所述接收端。
根据本申请的吸奶器，通过在奶瓶盖中设置贯穿第一透光件的第一隔光件，在第二透光件内设置贯穿其的第二隔光件，当发射端发射出的光线在奶瓶盖和第二透光件内发生折射后会被第一隔光件和第二隔光件隔断，无法传输到接收端，使得接收端只接收到奶瓶内液面反射回的光线，提升了奶瓶内奶量识别的准确度。
下面参考图2～图14对本申请的吸奶器进行解释和说明。其中，图2示出了根据本申请一个实施例中的吸奶器的立体分解示意图；图3示出了根据本申请一个实施例中的奶瓶盖的结构示意图；图4示出了根据本申请一个实施例中的发射端和接收端位于主机的中间的结构示意图；图5示出了根据本申请一个实施例中的发射端和接收端位于主机的侧边的结构示意图；图6示出了根据本申请一个实施例中的卡扣组件的结构示意图；图7示出了根据本申请一个实施例中的卡扣组件与盖耳扣合的结构示意图；图8示出了根据本申请一个实施例中的卡扣组件与盖耳脱离的结构示意图；图9示出了根据本申请一个实施例中的第二透光件处的立体分解示意图；图10示出了根据本申请一个实施例中的一种吸奶器识别奶瓶中奶量的示意图；图11示出了根据本申请一个实施例中的三通组件的剖面示意图；图12示出了根据本申请一个实施例中的三通组件的结构示意图；图13示出了根据本申请一个实施例中的压力传感器与抽气部件、发明阀门部件连通的结构示意图；图14示出了根据本申请一个实施例中的吸奶器的工作原理图。在不冲突的前提下，本申请各个实施例中的技术特征可以相互结合。

奶瓶盖212的尺寸、形状可以根据实际需要合理设定，例如圆形、椭圆形等，图3中的奶瓶盖212仅是一种示例，在此不对其进行具体限定。
奶瓶盖212的材质可以选取为玻璃、塑料、硅胶等，材质需要满足相应的食品安全标准。在一些情况下，对奶瓶盖212进行清洗时需要高温水煮杀菌处理，因此，奶瓶盖212的材质还需要耐受一定的高温，本申请不对奶瓶盖212的具体材质做限定。
奶瓶盖212与奶瓶211之间存在多种连接方式，例如螺纹连接、扣合连接或者奶瓶盖212直接塞入奶瓶211内等，本申请不对奶瓶盖212与奶瓶211之间的连接方式做限定。
奶瓶盖212上除进液口外，可以部分区域由第一透光件2121构成，也可以全部由第一透光件2121构成，第一透光件2121对应于奶瓶211内部的区域，对奶瓶211内的奶量进行检测时，光线可以穿过第一透光件2121照射在奶瓶211中奶液的液面上。
第一透光件2121可以采用玻璃、塑料、硅胶等透光材质制成，材质需要满足相应的食品安全标准和耐高温标准，本申请不对第一透光件2121的具体材质做限定。

其中，发射端2211和接收端2212可以位于主机220的中间(如图4所示)，也可以设置于主机220的侧边(如图5所示)，本申请不对发射端2211和接收端2212的设置位置进行限定。
发射端2211和接收端2212的设置数量可以是一个，也可以是多个。在发射端2211和接收端2212的设置数量为多个时，可以对多个发射端2211和接收端2212检测到的奶量数据进行分析比较，排除检测误差大的数据，从而提高对奶瓶211中的奶量检测的准确度。
可选地，测距组件221可以采取为TOF测距组件、红外测距组件、激光测距组件等，本申请对测距组件221的具体类型不做限定。根据采取的测距组件221的不同，第一透光件2121也有所不同。示例性地，测距组件221采取为红外TOF测距组件，发射端2211是TOF发射端，其发射红外光线，接收端2212是TOF接收端，其能够接收红外光线，对应的，第一透光件2121是红外透光板，其可以使红外光线透过。

可选地，卡扣2221可以包括一个或多个卡扣，对应地，奶瓶盖212上也可以设置一个或多个盖耳。设置多个卡扣和盖耳时，多个卡扣之间可以对称设置或者按照其他方式进行设置，多个盖耳之间也可以对称设置或者按照其 他方式进行设置，本申请对卡扣和盖耳的数量以及设置方式不进行限制。示例性地，结合图7和图8，卡扣2221包括对称设置的第一卡扣22211和第二卡扣22212，盖耳包括对称设置的第一盖耳2122和第二盖耳2123，所述第一卡扣22211用于与所述第一盖耳2122扣合，所述第二卡扣22212用于与第二盖耳2123扣合。
可选地，卡扣2221的材质可以采用塑料、橡胶等，需要满足相应的食品安全标准，本申请对卡扣2221的材质不进行限制。
在一个示例中，如图6所示，所述卡扣组件222还包括卡扣变形圈2222和设置在所述卡扣变形圈2222上的卡扣按键2223，卡扣2221设置卡扣变形圈2222上。通过按压卡扣按键2223使卡扣变形圈2222发生形变，从而带动卡扣2221与盖耳进行脱离或者与扣合。
示例性地，卡扣变形圈2222采取弹性材料制成，例如橡胶、弹性塑料等，所采取的弹性材料应当足够好，保证在可穿戴式吸奶器的寿命范围内无塑性变形或者断裂风险。此外，卡扣变形圈2222的材质满足相应的食品安全标准。
可选地，卡扣变形圈2222的尺寸、形状可以根据实际需要合理设定，例如圆形环、椭圆环等，在此不对其进行具体限定。
在一个示例中，主机220还包括设有滑槽的壳体，所述卡扣2221滑动设置于所述滑槽内，所述卡扣按键2223用于驱动所述卡扣变形圈2222形变以使所述卡扣2221沿滑槽滑动并与盖耳脱离。
结合图6和图8，在吸乳结束后，按照如下的方式取下奶瓶组件210：按压卡扣按键2223，卡扣变形圈2222受力发生形变，卡扣2221随着卡扣变形圈2222的形变在滑槽内向外扩张滑动，从而与盖耳发生脱离，使奶瓶组件210从可穿戴式吸奶器上取下。结合图6和图7，在进行吸乳时，可以采取如下的方式安装奶瓶组件210：按压卡扣按键2223，卡扣变形圈2222受力发生形变，卡扣2221随着卡扣变形圈2222的形变在滑槽内向外扩张滑动，将奶瓶组件210放置在卡扣组件222对应位置，松开卡扣按键2223，卡扣变形圈2222恢复原状，驱使卡扣2221反向滑动与奶瓶盖212上的盖耳扣合在一起，从而将奶瓶组件210与主机安装在一起。
此外，由于卡扣2221滑动设置在主机的壳体内，在奶瓶组件210通过卡扣2221与主机220安装在一起时，壳体对奶瓶盖212起到限位作用，从而提高安装的牢固性。
可选地，主机220的壳体可以是一体成型的，也可以是由多个分壳体组合而成的。示例性地，如图2所示，壳体由主机面壳2231、主机下壳2232、主机前壳2233等多个分壳体组合而成。滑槽设置在朝向且靠近奶瓶组件210的主机下壳2232内，奶瓶组件210与主机安装在一起时，主机下壳2232起到限位作用。
在本申请的一个实施例中，结合图3和图10所示，可穿戴式吸奶器还包括隔光件，隔光件包括第一隔光件2131，第一隔光件2131设置于所述第一透光件2121内并贯穿所述第一透光件2121，用于至少部分阻隔发射端2211所发射的光线被所述第一透光件2121折射后进入所述接收端2212，也即其用于阻隔的是发射端2211发射的未到达奶瓶内的液面的光线。
在一个示例中，结合图9和图10，可穿戴式吸奶器还包括第二透光件214，第二透光件214设置在所述测距组件221和所述奶瓶盖212之间，所述隔光件还包括第二隔光件2132，所述第二隔光件2132设置于所述第二透光件214内并贯穿所述第二透光件214，用于至少部分阻隔所述发射端2211所发射的光线经所述第二透光件214折射后进入所述接收端2212。
可选地，第二透光件214设置在奶瓶盖212上，对应于第一透光件2121的位置。第一隔光件2131设置在第一透光件2121的中部，第二隔光件2132设置在第二透光件214的中部。发射端2211和接收端2212位于第二透光件214背向奶瓶盖212的一侧，发射端2211和接收端2212间隔地设置在第一隔光件2131和第二隔光件2132的两侧，且与第一隔光件2131和第二隔光件2132等距离，也可以具有不同的距离。
结合图10，当奶瓶盖212上面轻微沾奶或者有水蒸气干扰，从测距组件221的发射端2211发出的光线会在第一透光件2121和第二透光件214内部发生折射，由于第一隔光件2131的存在，在第一透光件2121内发生折射的光线会被第一隔光件2131隔断，从而使得第一透光件2121内发生折射的光线无法传输到测距组件221的接收端2212，由于第二隔光件2132的存在，在第二透光件214内发生折射的光线会被第二隔光件2132隔断，从而使得第二透光件214内发生折射的光线无法传输到测距组件221的接收端2212，接收端2212只接收到奶瓶211内液面反射回的光线，提升了奶瓶211内奶量识别的准确度。
第一隔光件2331和第二隔光件2132采取不透光材质制成，根据不同类 型的测距组件221，第一隔光件2131和第二隔光件2132可以采取为不同的材质，本申请对第一隔光件2131和第二隔光件2132的具体材质不做限定。示例性地，当测距组件221采取为TOF测距组件，且TOF测距组件的发射端发射红外光线时，第一隔光件2131和第二隔光件2132可以由为红外隔光材质制成。第一隔光件2131和第二隔光件2132的材质还应当满足相应的食品安全标准和耐高温标准。
第二透光件214可以采用玻璃、塑料、硅胶等透光材质制成，材质需要满足相应的食品安全标准和耐高温标准，本申请不对第二透光件214的具体材质做限定。根据采取的测距组件221的不同，第二透光件214也有所不同。示例性地，测距组件221采取为红外TOF测距组件，发射端2211是TOF发射端，其发射红外光线，接收端2212是TOF接收端，其能够接收红外光线，对应的，第二透光件214是红外透光板，其可以使红外光线透过。
在一个示例中，所述发射端2211和所述接收端2212间隔设置且位于所述第二透光件214背向第一透光件2121的一侧，所述隔光件213位于第二透光件214和第一透光件2121内对应于发射端2211和接收端2212之间的区域。
其中，发射端2211和接收端2212的设置位置对应于第一透光件2121和第二透光件214，以使发射出的光线能够穿过第二透光件314和第一透光件2121到达液面，以及液面反射的回光能够穿过第一透光件2121和第二透光件214回到接收端2212。隔光件213设置在对应于发射端2211和接收端2212之间的位置，发射端2211段发射出的光线在第一透光件2121和第二透光件214内发生折射时，由于隔光件213对应位于所述发射端2211和接收端2212之间，从而隔光件213对前述发生折射的光线进行阻隔，发生折射的光线无法传输到接收端2212，提升了奶瓶211内奶量识别的准确度。示例性地，如图10所示，发射端2211和接收端2212设置于奶瓶盖212朝向主机的一侧，第一隔光件2131和第二隔光件2132分别位于第一透光件2121和第二透光件214内且正对于发射端2211和接收端2212的中间位置。
在一个示例中，所述第一隔光件2131的第一端与所述第二隔光件2132的第一端抵接，所述第一隔光件2131的第二端与所述奶瓶盖212的朝向所述奶瓶211内的表面齐平，所述第二隔光件的第二端抵接所述测距组件朝向所述奶瓶盖所在一侧的表面。
在一个示例中，奶瓶211的底部设有遮光涂层。其中，在空瓶状态下， 当奶瓶211的底部是透明材质时，发射端2211发出的光线穿透奶瓶211的底部，之后反射回接收端2212，从而影响空瓶判断。在奶瓶211的底部设置遮光涂层后，发射端2211发射出的光线遇到遮光涂层后会被隔断，无法穿过奶瓶211的底部，从而提高了空瓶判断的准确度。
可选地，遮光涂层不直接与奶瓶211内的奶液接触，避免影响奶液的品质。
遮光涂层可以是任意具有遮光性的材料，例如遮光涂层可以包括氧化钛、炭黑等，遮光涂层需要满足相应的食品安全标准。

在一个示例中，如图11所示，三通构件231包括三通组件支架2312，三通组件支架2312位于三通构件231的内部，对柔性吸乳罩232起到支撑作用。
在一个示例中，如图11和图12所示，柔性吸乳罩232包括与乳房相匹配的槽形气垫2321。其中槽形气垫2321根据人体工程学设置在柔性吸乳罩232上，能够很好的匹配乳房。在吸乳过程中，槽形气垫2321与乳晕接触，实现密封效果，同时，在吸乳过程中，当柔性吸乳罩232吸附在乳房上时， 槽形气垫2321对乳晕起到有效的按摩作用，从而增强吸乳过程中的舒适度、提高吸乳效率与出奶量。
在一个示例中，如图11和图12所示，柔性吸乳罩232包括与乳头相匹配的吸乳孔2322。在吸乳过程中，乳头位于吸乳孔2322的内部，乳房与柔性吸乳罩232抵接，吸乳孔2322通过人体工程学模拟出人体适宜的乳头吸乳尺寸，从而增强吸乳过程中的舒适度、提高吸乳效率与出奶量。

在一个示例中，如图2所示，三通组件230还包括可变形腔体233，所述可变形腔体233能够通过自身形变产生使所述柔性吸乳罩232吸出奶液的负压。
可变形腔体233是由弹性材料制成的腔体，可变形腔体233的形状可以为任意适合的形状，例如球形空腔、立方体空腔、碗形空腔等。示例性地，在图2中，可变形腔体233为弹力碗。可变形腔体233通过三通构件231与柔性吸乳罩232连通，对可变形腔体233的内部进行抽气，使可变形腔体233发生变形并在三通组件230内部形成负压，通过形成的负压对乳房形成吸力，使柔性吸乳罩232吸附在乳房上，并进一步吸取出奶液。
可选地，三通构件231还包括第二安装部，可变形腔体233设置于所述第二安装部上。可变形腔体233与第二安装部连通，第二安装部与第一安装部连通，第一安装部与柔性吸乳罩232，进而使得可变形腔体233与柔性吸乳罩232连通。
在一个示例中，如图2所示，三通组件230还包括单向阀234，所述单向阀234设置于所述奶瓶盖212并位于所述进液口处，用于构成被吸出的奶液流向所述奶瓶211的通路。
其中，单向阀234通过三通构件231与柔性吸乳罩232连通，当柔性吸乳罩232从乳房中吸取出奶液后，吸取出的奶液通过三通构件231流向单向阀234，并通过单向阀234流入到奶瓶211中。此处设置单向阀234可以保证奶液只能单向地从单向阀234流入到奶瓶211中，而不会从奶瓶211中通过单向阀234流出来。
可选地，三通构件231还包括第三安装部，所述单向阀234设置于所述 第三安装部。单向阀234与第三安装部连通，第三安装部与第一安装部连通，第一安装部与柔性吸乳罩232，进而使得柔性吸乳罩232吸取出的奶液经过第一安装部和第二安装部流向单向阀234。

其中，结合图14，抽气部件225进行抽气后，压力传感器226检测抽气部件225抽气后气流通道内的压力值。当抽气部件225长时间运行出现衰减的时候，压力传感器226会识别到气流通道内气压值减小，压力传感器226向主板224发送压力值减小数据，主板224根据压力值减小数据控制抽气部件225提高抽气效率，从而对抽气部件225形成反馈过程，使得抽气部件225在出现抽气效率衰减后能够进行补偿提高，进而保证吸乳操作在一个稳定的负压环境下进行，提高吸乳过程中的舒适度。
相应地，在抽气过程中，当压力值突然增大后，压力传感器226也可以向主板224发送压力值增大数据，主板224根据压力值增大数据控制抽气部件225降低抽气效率，进而保证吸乳操作在一个稳定的负压环境下进行，提高吸乳过程中的舒适度。
在一个示例中，结合图13和图14，主机220还包括进气通道和阀门部件227，所述进气通道和所述气流通道连通，所述阀门部件227设置于所述进气通道，用于关断或开启所述进气通道。

可选地，阀门部件227可以通过用户手动关闭和开启，或者阀门部件227与主板224电连接，通过主板224控制阀门部件227关闭和开启。示例性地，当阀门部件227与主板224电连接时，可以选取为电磁阀。

其中，可穿戴式吸奶器上可以只集成有电源250，通过集成的电源250对可穿戴式吸奶器进行供电；或者，可穿戴式吸奶器可以仅外界获取电能而不集成电源250；或者，结合图2，在可穿戴式吸奶器上既集成有电源250，也可以从外界获取电能，具体的，可穿戴式吸奶器上设有插头260，通过插头260从外界获取电能。
