具体实施方式
下面通过具体实施方式结合附图对本实用新型作进一步详细说明。
请参考图1、图2、图3及图4所示，一种电动吸奶器的主机的实施例，包括供电电源、主机壳体2、设置在主机壳体2内的泵体壳体1、设置在泵体壳体1内的泵体4、由泵体4吸气端延伸至主机壳体2外的气管3，所述泵体壳体1由泵壳上壳体1a和泵壳下壳体1b拼合构成。所述泵壳上壳体1a和泵壳下壳体1b紧密配合构成封闭内腔，在泵体壳体1上还设置有连通该封闭内腔与泵体壳体1外部空间的气孔1c。因为主机工作时，噪音最主要来源即泵体4，本专利该结构实现对泵体4工作空间的最大化封闭，有效阻隔泵体工作噪音向外传递的路径，从而有效降低电动吸奶器的主机的工作噪音。同时，单独设置气孔1c，又保证了泵体4工作时的排气需要，同时保证噪音传递路径的最小化。
实施时，对于泵体壳体1内泵体4或其他配件的供电线路的走线，可以经过泵体壳体1上对应设置走线孔(开孔较大，装配后需要适当做密封处理)，或者直接从所述气孔1c处走线。
实施时，如图3所示，泵壳上壳体1a和泵壳下壳体1b通过在拼合面增设密封圈5实现紧密配合。因为泵壳上壳体1a和泵壳下壳体1b通常通过卡口或螺钉连接固定在一起，在此连接过程对密封圈5进行压迫，实现拼合空间的密封。设置密封圈5的密封形式，操作效率高于其它方式，且便于后期维护、装配。从图3可看出，密封圈5是对应泵体壳体1拼合面/拼合线的一个环形封闭结构的密封圈体，具体形状根据实施时候的不同情况对应变化。
实施时，如图9所示，密封圈5可以设置为截面呈H形，该形状密封圈5的上下开孔正好与泵壳上壳体1a或泵壳下壳体1b的边界咬合，保证配合密封效果，且保证装配准确。实施时，密封圈5可选用硅胶密封圈，因为硅胶质地柔软，无毒害，并且性质稳定如耐高温等，可有效保证密封效果。
实施时，具体的如图3图5所示，所述泵体4包括电机4a和将电机的输出的动力转换为气流压差的工作部4b，所述工作部4b还包括有进气口4b1和排气口4b2；所述电机4a设置在泵体壳体1内腔靠近所述气孔1c一端，所述排气口4b2设置在泵体壳体1内腔相对远离所述气孔1c的一端。这样如图6所示，在泵体4工作产生由进气口4b1到排气口4b2方向的气流时，由于排气需要，在排气口4b2和气孔1c之间也会形成气流，而将电机4a设置在靠近气孔1c处保证了其在气流的路径之中，故可有效实现通过气流对电机4a进行散热，巧妙地利用工作气流保证电机4a的工作稳定的提高产品可靠性。
实施时，具体的如图3图5所示，所述泵体壳体1内还设置有气流控制电磁阀7，该气流控制电磁阀7设置在所述排气口4b2与气孔1c之间。因此利用泵体4工作气流实现了对电磁阀7的散热。
如图3所示，实施时，具体的，电磁阀7包括主体、进气口7a和排气口7b。主机工作时，通过电磁阀7的开闭，进气口7a和排气口7b在导通与封闭间切换，从而在与进气口4b1对应的气管3中形成低压与常压的变换。当进气孔7a进气时，与进气口4b1对应的气管3旁通到大气形成常压。当进气孔7a封闭时，与进气口4b1对应的气管3被泵抽吸形成负压。
实施时，如图3图5所示，在所述泵体壳体1与泵体4之间设置有起缓冲减震作用的减震海绵6。减震海绵6为海绵材质或其他中空具有大量贯通结构的缓冲材料，其可起到缓冲消除震动、降低噪音、消除刚性碰撞，同时可保证气流/气路的顺利通过。
实施时，如图2、图3、图4及图5所示，泵体壳体1外部设置有至少三个限位卡扣1d(3个就可以以稳定的定位)，在主机壳体2中设有与所述限位卡扣1d数量对应的减震垫9，所述减震垫9包括用于与主机壳体2连接定位的下部和用于与所述限位卡扣1d卡接配合的上部，所述泵体壳体1通过该减震垫9连接定位在所述主机壳体2中。这种结构保证了泵体壳体1不直接与主机壳体2接触，通过减震垫9的定位方式保证泵体壳体1的震动最小化的路径传递到主机壳体2，同时，减震垫9结构，能实现对震动的缓冲与削弱，减小吸奶器工作震动与噪音。
具体的，如图3图4所示，实施时，减震垫9为F形外截面的柱状体，限位卡扣1d可为C形结构，装配时，直接将减震垫9的F形侧槽嵌入限位卡扣1d 即实现装配。为此，为防止两者脱落，限位卡扣1d上上部对限位限位卡扣1d限位的平面可设置为椭圆形。减震垫9内部为凹字形中部贯通体，贯通部台阶面用于配合螺钉10实现与主机壳体2连接。
实施时，如图2、图4及图7所示，供电电源包括一设置在所述主机壳体2上的用于安装蓄电池进行供电的电池仓8，该电池仓8相对于所述主机壳体2为一个封闭空间。即两者是相互独立的，电池仓8通过仓体盖板实现关闭。从而保证了主机壳体2内的噪声不会经过该电池仓8传递到主机壳体2外部。电池仓8的这种相对主机壳体2内腔的封闭结构，可以是同时本身的装配结构设置实现，也可以是在装配后再密封处理实现。
实施时，具体的如图7、图10及图11所示，所述电池仓8包括仓盖、设置在其内腔两侧的滑槽和电极接触弹片，所述电极接触弹片由所述设置仓盖一侧嵌入所述滑槽中。其中仓盖用于遮盖电池仓8的内腔(内部空间)，滑槽用于电极接触弹片装配时导向和限位，电极接触弹片用于接触电池正/负极并将其与主机内部的电路连接导通。电池仓8内，一侧的滑槽对应设置两个正负极一体的电极接触弹片，另一侧的滑槽则对应设置四个电极接触弹片分别为两个正电极接触弹片和两个负电极接触弹片。
该电池仓8这种结构即单边上下压簧型仓，和过往技术一样，这种电池仓安装电池容易并且可靠，但过往技术下面的压簧(正电极接触弹片)要从壳体内部安装，这就要在电池仓在底面开口，而且开口要足够大以让压簧通过。这样的结构使壳体内外的密封性大大降低，降噪性也降低。本机的电池仓经过改进，压簧从外部装入，而装弹片的开口不在底面在侧面，正好能被弹片本身遮挡住，这就使得电池仓与壳体内部没有明显的开口，减小了噪音的向外传递。
实施时，如图7、图10及图11所示，主机壳体2背面沿边缘位置还设有一个凹陷区域14，在该凹陷区域14设置有用于将主机壳体2别在腰带上的扣板13。因为扣板13的结构因素，其本身都需要有一定的厚度，从而扣板13的设置往往使得吸奶器主机的厚度增加，且主机壳体2背面的垫脚厚度需要对应加高，影响主机外观，本专利该方案，通过凹陷区域14的设置，对应抵消了扣板13厚度对主机背部外观的影响，视觉效果简洁精致，使用中避免了磕磕碰碰的情况出现。
实施时，如图7所示，供电电源包括一外部电源接口11，该外部电源接口 11设置在主机壳体2上相对于设置所述气管3位置的另一端。所述气管3与外部电源接口11呈直线排布，分别位于主机壳体2的上下方。气管3与外部电源接口11直线排布外观简洁，提高了主机的可操作性，在操作中气管3与外部电源接口11不会阻碍手握主机。实施时，气管3与外部电源接口11可以是分别位于主机的上下方。
实施时，如图1、图8所示，所述主机壳体2正面还设置有操控面板15，所述操控面板15处还设置有LCD显示屏16，该LCD显示屏16上设置有用于对应显示吸放气时间操控调节状态的吸放气时间级数显示条16a。吸奶器调节的自定义功能在LCD屏的辅助下调节变得容易及准确，可以看着调，方便直观，实施时，吸放气时间级数显示条16a多级段设置，如每一级的时间可设为为0.5秒。现有的吸奶器，自定义功能没有LCD屏级数显示辅助，只能估计吸放气时间，使用不便。
本实用新型，电动吸奶器力大舒适、调节均衡，有效降噪技术实现超低噪音，比现有吸奶器低5-9分贝，特别适合妈妈晚上吸奶使用。采用LCD显示，吸奶状态一目了然，使用操作直观便捷。便携设计，支持电源和电池两种供电模式，方便外出便携使用。
以上内容是结合具体的实施方式对本实用新型所作的进一步详细说明，不能认定本实用新型的具体实施只局限于这些说明。对于本实用新型所属技术领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本实用新型的保护范围。
