具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考图1-图3描述根据本发明实施例的泵浦用的活塞100。
根据本发明实施例的泵浦用的活塞100，如图1-图3所示，包括：基座盘1、活塞囊2、实体3和连杆4，活塞囊2设在基座盘1的一侧，实体3设在活塞囊2的远离基座盘1的一侧，连杆4设在实体3的远离基座盘1的一侧，活塞囊2内限定出囊腔20，囊腔20在朝向基座盘1的一侧敞开。
当活塞100工作时，动力元件带动活塞100的连杆4往复运动，活塞100的连杆4拉动实体3往复运动，实体3挤压活塞囊2，从而改变活塞囊2内的囊腔20的容积大小。囊腔20容积变大时完成吸入动作，囊腔20容积变小时完成排出动作，因此连杆4的往复运动，可实现泵浦往复进行吸入流体和排出流体的目的，从而可源源不断地驱动流体朝向特定方向流动。
当活塞100应用到一种特定的泵浦，该泵浦外壳的内径尺寸为D23-D29mm，如图3所示，这种泵浦内的活塞100的结构参数需要同时满足以下条件：
活塞囊2为圆柱形，囊腔20为圆柱腔，囊腔20的内径d1为9.2±0.5毫米，囊腔20的深度h1为3.8±0.5毫米，活塞囊2的壁厚w为0.5±0.3毫米；
活塞囊2的外周面的连接基座盘1的部分沿径向向外凸出以形成保护套21，实体3为圆柱形。
活塞100的结构采用上述优化的参数后，可以实现泵浦稳定的负载流量：耗电少、出水量稳定，且可以实现泵浦的高寿命。有的泵浦，该泵浦外壳的内径尺寸为D26mm，活塞100的结构采用上述优化的参数：活塞囊2为圆柱形，囊腔20为圆柱腔，囊腔20的内径d1为9.2±0.5毫米，囊腔20的深度h1为3.8±0.5毫米，活塞囊2的壁厚w为0.5±0.3毫米，泵浦的寿命可多达1000小时以上。
为更能理解本发明实施例的活塞100采用优化的参数后，能提高泵浦(该泵浦的泵浦外壳的内径尺寸为D23-D29mm)性能，发明人将本发明实施例的结构参数的活塞100置于一种水泵中进行了试验，并将另一个结构参数未优化的活塞也置于同结构的水泵中也进行了同样试验，并将两组水泵试验后的试验结果进行了参数对比。其中，该水泵中泵 浦外壳的内径为23-29mm，不同试验中除活塞100外，泵浦的其他构件的结构、参数均相同。
表1：泵浦在采用不同结构参数的活塞后试验结果对比表
Figure PCTCN2017078883-appb-000001
表1中10组数据均是两种水泵在(DC9.3V、水泵吸程0.1m、负载3.5psi、时间31秒)同等条件下测出的电流和出水量的试验结果对比。
由多组数据统计出的对比结果可以证明，在同样的工作条件下，采用本发明实施例的活塞的水泵耗电少且出水量稳定。多组数据的结果对比，也证明了上述结论是客观的、经过验证后的结果。
下面结合图1-图3描述根据本发明的一个具体实施例中活塞100的结构。
在该实施例中，活塞囊2为多个，多个活塞囊2均设在基座盘1的一侧，每个活塞囊2的远离基座盘1的一侧均设有一个实体3，每个实体3的远离基座盘1的一侧连接有一个连杆4。这样，相当于多个活塞囊2通过基座盘1连接在一起，从而可简化结构，方便组装拆卸。而且多个活塞囊2实现了并联，驱动更加简单。
具体地，活塞囊2有三个，活塞100对应地设有三个实体3和三个连杆4。
具体地，多个活塞囊2呈圆形，且多个活塞囊2环绕基座盘1的中心轴线排布。这样，多个活塞囊2排布紧凑，减小活塞100的尺寸。
其中，基座盘1为圆形盘，基座盘1的中心处设有在基座盘1的厚度方向上贯通的中心孔12，中心孔12为与基座盘1同心的圆孔。
在该实施例中，基座盘1的边缘处设有间隔开的多个缺口11，每个缺口11在基座盘1的厚度方向上贯通基座盘1，且每个缺口11在朝向基座盘1的外周方向上敞开。
每个缺口11均位于相邻两个活塞囊2之间，基座盘1的位于相邻两个活塞囊2之间的部分上设有贯通的边孔13，边孔13在远离连杆4的一端设有倒角。
具体地，边孔13设在相应缺口11的中心线处。
具体地，如图3所示，囊腔20的开口边缘处设有倒角，这样可方便活塞100加工时脱模，还有利于泵浦中阀片与活塞配合。另外，囊腔20的底壁与周壁之间通过圆弧面连接。
基座盘1的远离连杆4的一侧设有环绕囊腔20的开口的接环16，接环16为圆环。在图2可以看出，多个囊腔20的接环16在连接处连接为一体。
可选地，基座盘1在相邻两个缺口11之间构成外缘14，每个外缘14的底部均设有凸块15，即每个外缘14的朝向连杆4的一侧设有凸块15。凸块15的设置用于活塞100与其他部件的配合连接。
具体地，每个外缘14上设有两个凸块15，两个凸块15设在外缘14的周向上的两侧。
在该实施例中，连杆4的部分外周壁向外凸出形成卡块41，卡块41的设置可便于动力元件连接活塞100，例如动力元件可通过卡在卡块41与实体3之间，以避免与活塞100相脱离。
其中，卡块41的外周面形成为弧面，从而可减小磨损。
综上，本发明实施例的活塞100，活塞囊2的变形挤压更加容易实现，可以避免磨损，提高产品的使用寿命。
根据本发明实施例的泵浦，包括根据本发明上述实施例的泵浦用的活塞100。由此，根据本发明实施例的泵浦，通过采用本发明优化参数后的活塞100，可实现泵浦耗电少、出水量稳定，且可以实现泵浦的高寿命，有的泵浦的寿命可多达1000小时以上。
