目前市场上销售的奶瓶，因婴儿在吸吮的过程中，容易使空气进入奶瓶而使奶瓶内产生气泡，这些含有气泡的奶被婴儿吸吮后进入腹内，容易发生打嗝、呛奶、肠绞痛等现象，不利于婴儿的健康成长。为了解决这一问题，市场上公开的奶瓶大都在奶瓶的瓶口或瓶盖处设有防胀气装置，早产儿和新生儿有频繁喂养频繁清洗和冲奶的需求，用户使用过程中需要将奶嘴头、瓶盖和瓶体依次拆分清洗，拆装的过程繁琐；或在奶瓶内设置独立单向阀功能部件，可能导致婴儿误吞误食风险，安全性低下；部分奶瓶在底部设置有防胀气阀，但是防胀气孔容易与桌面直接接触粘入灰尘，不够干净卫生。

具体实施方式
下面结合实施例对本公开作进一步描述。但本公开并不限于以下实施例。实施例中采用的实施条件可以根据具体使用的不同要求做进一步调整，未注明的实施条件为本行业中的常规条件。本公开各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
在下文中，仅简单地描述了某些示例性实施例。正如本领域技术人员可认识到的那样，在不脱离本公开实施例的精神或范围的情况下，可通过各种不同方式修改所描述的实施例。因此，附图和描述被认为本质上是示例性的而非限制性的。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
在本公开实施例中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
在本公开的描述中，方位词“上”、“下”均是基于奶瓶竖直放置(如放置在桌面等承载面)上的状态(如图2、10、12、15和16所示)所定义的，如附图2中，图中的上侧方向为“上”，图中的下侧方向为“下”，对于上述方向的定义仅仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。所述“接合”包括直接连接、间接连接、可拆卸连接、不可拆卸连接等。
如图1至图16所示，本实施例中的防胀气奶瓶包括连接件1、瓶体2、奶嘴部3、底托4及防尘盖5，连接件1设置在瓶体2的上方，瓶体2具有上端开放的腔体21，瓶体2的下部设有与腔体21连通的防胀气通孔22。瓶体2通过连接件1与奶嘴部3可拆卸连接可以理解为：连接件1可以为奶嘴部3的一部分，瓶体2通过连接件1与奶嘴部3可拆卸连接，连接件1为瓶体2的一部分，奶嘴部3通过连接件1与瓶体2可拆卸连接，或连接件1与奶嘴部3和瓶体2分别可拆卸连接，或连接件1与奶嘴部3和瓶体2为一体结构，不可拆卸。
具体的，如图3至图6所示，底托4为硅橡胶材料，包括固定部41及连接于固定部41上的单向进气阀42。固定部41为环状并沿着瓶体2下侧的外周侧套设，单向进气阀42插在防胀气通孔22中以仅允许空气进入腔体21内，防胀气通孔22设于瓶体2的下部，例如瓶体2的外周侧壁上并靠近瓶体2的底部，或瓶体2的底部并靠近瓶体2的外周侧壁，或瓶体2的外周侧壁与底部的交叉处。单向进气阀42使空气单向地通过防胀气通孔22以进入瓶体2内的，该 单向进气阀42可以固定连接于底托4的固定部41上，还可以和底托4的固定部41一体设置。在一实施例中，如图3所示，防胀气通孔22邻近瓶体2的底部设置，例如设置在瓶体2的位于底部和顶部之间且靠近底部的侧壁上。
单向进气阀42被配置为当瓶体1与奶嘴部3连接时，奶嘴头32和单向进气阀42相对瓶体大致呈斜对角布置。如图7和图8所示，奶瓶在使用状态时，倾倒奶瓶喂奶使奶嘴头32被婴幼儿含入口中，此时奶液向下，奶瓶中的空气会向瓶体的较高位置(与奶嘴头32相对，基本靠近瓶体2的底端部)汇集，防胀气通孔22即设置在该汇集区域处，在婴幼儿吮吸奶液的过程中，外界的空气会自防胀气通孔22上的单向进气阀42进入到奶瓶的较高位置处，避免瓶体2内形成真空，同时该进入的空气流又不会对奶液引起较大的扰动，避免在奶液中形成气泡；而且防胀气通孔22不会没于液面之下。
还需要说明的是，如图8所示，瓶体2具有一个沿上下方向延伸的中心轴线C，该中心轴线C穿过瓶体2的顶端部和底端部各自的圆心或几何中心线。例如，瓶体2整体为三棱柱状，则该中心轴线C为该棱柱的中心线，穿过瓶体2的顶端部和底端部各自的几何中心点。奶嘴头32偏离瓶体2的中心轴线C设置。其中，防胀气通孔22位于中心轴线C的第一侧，奶嘴头32位于中心轴线C的第二侧，第一侧和第二侧不同。进一步地，防胀气通孔22和奶嘴头32分别位于中心轴线C的相对两侧。例如，在使用状态时，防胀气通孔22位于中心轴线C的上侧，奶嘴头32位于中心轴线C的下侧。上述的“斜对角布置”即指奶嘴头和单向进气阀一高一低设置且处于中心轴线C的相对两侧。
单向进气阀42包括鸭嘴阀421，单向进气阀42和防胀气通孔22的四周孔壁紧密贴合，鸭嘴阀421具有阀腔4211及与阀腔4211连通的进气口4212和出气口4213，进气口4212的面积大于出气口4213的面积，单向进气阀42及鸭嘴阀421都具有弹性，出气口4213为狭缝状且仅在腔体21为负压状态时打开，婴儿吸吮奶嘴头32时，鸭嘴阀421的内部产生负压进气，但不排气。
底托4还包括凸缘提手43，凸缘提手43设置在单向进气阀42的上侧和单向进气阀42一体设置或固定连接；防胀气通孔22的上方设有开口向下的内凹卡槽23，凸缘提手43和内凹卡槽23卡合。如图3至图5所示，凸缘提手43上还设置有提手凸起部431，由于底托4在箍紧状态下处于收紧状态，设置提手凸起部431可以更好的帮助用户进行提拉，防止滑脱，也用于增加使用者的触感。如图4所示，需要将底托4和奶瓶拆分时，使用者只需要以提拉的方式抽拉凸缘提手43，同时将单向进气阀42从防胀气通孔22中抽出，并向下移动固定部41即可实现底托和奶瓶的脱离，使用者拆装方便，特别针对早产儿和新生儿频繁喂养产生的频繁清洗和 冲奶的问题，且底托处于底侧部位，避免了与桌面直接接触。
如图9和图10所示，瓶体2的底部的外径小于上部的外径以形成凹陷部位24，凹陷部位24上开设有第一固定凹槽241，底托4位于凹陷部位24中，底托4上部的固定凸缘44和第一固定凹槽241卡合。在其它一些实施例中，如图11和图12所示，凹陷部位24的外径自上而下逐渐增大，使得固定部41可以更好的与瓶体2箍紧。固定部41具有弹性且固定部41的直径小于凹陷部位的直径，使用时沿着瓶体2的下侧套设在瓶体2的外周侧，解决了如独立单向阀功能部件塞于瓶体侧孔可能导致婴儿误吞误食风险，同时起到了加固组装和固定的作用。
如图15和图16所示，连接件1的上部设有和奶嘴部3配合的定位槽11，奶嘴部3设有定位件312，定位槽11与定位件12相配合(即将定位件12对准定位槽11并置于定位槽11中)可以方便使用者确定奶嘴部的装配方向。如图10和图12所示，奶嘴部3的下方还设有固定件317，瓶体2设置有第二固定凹槽242，连接件1的内侧设有第三固定凹槽13，固定件317定位在瓶体2上部的第二固定凹槽242和第三固定凹槽13内且被夹于第二固定凹槽242和第三固定凹槽13内，避免奶嘴部3、连接件1和瓶体2装配后发生松脱的情况。
如图4所示，瓶体2的上边沿设有螺旋形的螺口25，如图2所示，连接件1上设有与螺口25相匹配的螺纹10，连接件1和瓶体2通过螺口25上的外螺纹与设于连接件1上的螺纹10的配合而相互螺旋连接。结合图2和图4所示，螺口25可设有连续或间断外螺纹，连接件1上设有连续或间断的内螺纹，外螺纹和内螺纹配置为连接件1旋转到位后奶嘴头32位于与防胀气通孔22相对的一侧上。进一步地，螺口25设有限位部251，连接件1设有止挡部12，限位部251与止挡部12相互干涉，以使所述奶嘴头32移动至与单向进气阀22大致呈斜对角布置的位置时定位于所述位置。上述的限位部251与止挡部12可以设置于外螺纹和内螺纹的起始点和终止点，内螺纹和外螺纹的起始点和终止点的位置设计为当奶嘴部3拧紧到瓶体2上后，奶嘴头32恰好和防胀气通孔22位于对角位置上。
奶嘴部3的上方还设置有防尘盖5，当不使用奶瓶时可以将防尘盖5盖在奶嘴部3上防止灰尘沾到奶嘴部上。
如图7和图8所示，本实施例中的奶瓶在用户使用时有位置方向上的提示，奶瓶在俯视视角下为圆角三角形，组装后的底托4的单向进气阀42处于圆角三角形的一个顶角部位，奶嘴头32处在单向进气阀42的斜对角，倾倒奶瓶喂养时奶液液面始终远离单向进气阀42(即单向进气阀42处在圆角三角形的顶尖部，更进一步减少单向进气阀42被奶液没过风险)，可以防止液面没过进气阀后产生奶泡进入婴儿肠胃发生肠绞痛现象。本文中，“圆角三角形”具体是指三个顶角经过倒圆角处理的三角形。
如图17至图19所示，本实施例中的奶嘴部3为硅胶材料，主要包括主体部31、奶嘴头32及设置于主体部31和奶嘴头32之间的乳晕部分33，乳晕部分33逐步收缩以平滑过渡至奶嘴头32。
以下对奶嘴部3的具体结构及各组件的连接关系做具体介绍：
主体部1具有沿上下方向延伸的第一中心线3a，该第一中心线3a和瓶体2的中心轴线C相重合；奶嘴头32沿第二中心线3b延伸，该第二中心线3b和第一中心线3a之间构成锐角，本实施例中奶嘴头32的偏斜设计，可以减少看护人喂奶抬起时的高度，便于操作，也可以防止婴儿吮吸时过度抬头影响颈椎发育及中耳炎等问题。
奶嘴头32上设有出奶孔321，上述的中心线自出奶孔321的中部穿过。具体的，奶嘴头32包括与婴儿的上颚相配合的弯曲部322和与婴儿的舌头相贴合的平滑部323，弯曲部322位于奶嘴头32的距第一中心线3a较近的一侧，平滑部23位于奶嘴头32的距第一中心线3a较远的一侧，弯曲部323和乳晕部分33之间形成和婴儿的上颚相配合的凹陷。奶嘴头32设置平滑部323可以更好的贴合婴儿的舌苔，使得婴儿吸吮时减少更多空气吞入，预防肠绞痛；出奶孔321设于奶嘴头32的顶部至婴儿口腔上颚区，便于出液和还原母乳喂养状态。
奶嘴头32的平滑部323的内表面上设置有突筋3231，具体的，突筋231的上端不高于出奶孔321，突筋3231的下端低于出奶孔321，突筋3231为闭合的环状结构且和奶嘴头32一体成型，突筋3231可以设置为椭圆形结构也可以为跑道形结构。本实施例中在奶嘴头32的内部设置突筋结构，可以防止婴儿在吮吸时将奶嘴头粘连，导致不出液的情况；如图17所示，也可以根据突筋的位置确定奶嘴头的平滑部，进而将平滑部准确对准婴儿的舌苔。
乳晕部分33的外壁上开设有多个凹槽331，凹槽331环绕奶嘴头32布设且多个凹槽331的间距相同，该处设置波浪形的凹槽增加了乳晕部的可拉伸性，由于新生儿的口腔处于发育阶段，还原母乳乳头的柔软和可拉伸性，可以让奶嘴头有更好的灵活度，且婴儿在含涎时有触觉上的感知，模仿母乳乳晕的点状凸起，能更贴近母乳喂养的感受。
奶嘴部3可拆卸地安装于连接件1上，以方便清洗，并作为可更换的配件。奶嘴部3上设有环形的卡槽，连接件1具有位于卡槽内的卡合凸缘，奶嘴部3和连接件1上设有用于限定二者的相对位置的定位机构，定位机构被配置为当连接件连接到瓶体上后奶嘴头位于与防胀气通孔相对的一侧上。例如，在其中一些示例中，主体部31的外侧壁上形成有用于装配奶瓶连接件1的卡槽，卡槽具有位于弯曲部322一侧的第一部分313及位于平滑部323一侧的第二部分314，第一部分313的高度大于第二部分314的高度，主体部31的底部还设置有外凸缘，配合连接件4使用时可以起到定位作用并增强了密封性。瓶体2的内壁还设置倾斜面，可以防止奶 瓶倾倒时液体的留存，以方便婴儿更好地吮吸到奶瓶内的液体。
主体部31的下方还设置有用于和瓶体2配合的固定销317。在其它一些实施例中，主体部31的上部设置有单向的侧回气阀，起到了防胀气的作用。
该奶瓶的使用方法具体包括下述步骤：
(i)向瓶体2中加入小于或等于设定最大奶量的奶液；
(ii)将奶嘴部3装配到奶嘴连接环1上，然后连接于瓶体2上，使奶嘴头32位于与防胀气通孔22相对的一侧上；
(iii)将奶瓶倾斜，使奶嘴头32朝向下方，在瓶体2内形成位于奶液液面之上的空气区域，防胀气通孔22位于空气区域处并相互连通。
具体地，步骤(ii)中，使防胀气通孔22和奶嘴头32位于瓶体2的中心轴线C的相对两侧，优选为处于奶瓶的斜对角位置。
综上所述，本公开在奶瓶的底部设置有防胀气装置，防胀气装置的固定部沿瓶体下端的外周侧套设，拆装过程简洁，防胀气孔处于底部的侧面部位，避免与桌面直接接触粘入灰尘，且避免了婴儿误吞误食的风险，提高了奶瓶使用的安全性。
通过在奶嘴头的内壁设置突筋，防止婴儿吮吸过程中奶嘴头粘连，提高了奶嘴及奶瓶的安全性，且突筋设置在靠近奶嘴头平滑部的一侧，使用过程中可以快速判断奶嘴头中靠近婴儿舌头的一侧，起到了指示作用，能够帮助使用者快速识别奶瓶的正确使用朝向。
上述实施例只为说明本公开的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本公开的内容并据以实施，并不能以此限制本公开的保护范围。凡根据本公开精神实质所作的等效变化或修饰，都应涵盖在本公开的保护范围之内。
