Description

微型水泵 技术领域
本申请涉及水泵产品领域，尤其涉及一种微型水泵。
 背景技术
水泵，是一种输送液体或使液体增压的机械。它将原动机的机械能或其他外部能量传送给液体，使液体能量增加，常用于输送水、油、酸碱液、乳化液、悬乳液和液态金属等。

其中，安装壳的壳壁将绕线组件和叶轮组件分隔于不同的收容腔中，基于壳壁的强度要求和受限于壳壁的成型工艺水平，壳壁的厚度较大，会使得磁钢与绕组线圈所能利用的空间较少，进而导致驱动力减小。
 技术解决方案
基于此，有必要提供一种能够解决因壳体厚度大而导致磁钢与绕组线圈利用空间少的问题的微型水泵。

 本发明的实施方式
下面结合附图和实施方式对本申请作进一步说明。
请参阅图1-图5，本申请实施例提供一种微型水泵，包括：具有容纳腔140的安装壳100以及收容于容纳腔140内的叶轮组件300以及绕线组件600。
容纳腔140内设有金属件500以及用于安装绕线组件600的安装件400，金属件500将容纳腔140分隔为用于收容叶轮组件300的第一收容腔142以及用于收容绕线组件600的第二收容腔144。
金属件500具有周向延伸的周壁520以及分别与周壁520两端连接的第一折弯部530与第二折弯部510，第一折弯部530背离周壁520的中心延伸，且第一折弯部530与安装壳100连接，第二折弯部510朝周壁520的中心延伸，且第二折弯部510的中部连接有安装件400。
叶轮组件300套设在周壁520的外周且与第一折弯部530正对设置，绕线组件600设置在周壁520的内圈且与第二折弯部510正对设置。
上述提供的微型水泵，待输送或待增压的液体进入收容叶轮组件300的第一收容腔142内，叶轮组件300的磁场与绕线组件600的磁场相互作用，叶轮组件300绕绕线组件600转动。叶轮组件300转动并对第一收容腔142内的液体产生一定的推力，以使得第一收容腔142内的液体排出。
可以理解的是，使得叶轮组件300转动的驱动力来源于叶轮组件300与绕线组件600之间的相互作用。叶轮组件300与绕线组件600之间的作用力越大，叶轮组件300转动速度越快，微型水泵的输出或增压效果越好。上述微型水泵中，叶轮组件300套设在周壁520的外周，且叶轮组件300与第一折弯部530间隔设置。基于金属件500的壁厚，使得叶轮组件300用于感应磁场的部分体积增大。绕线组件600设置在周壁520的内圈，且绕线组件600与第二折弯部510间隔设置。同理，绕线组件600绕线部分能够缠绕的圈数增加，继而使得绕线组件600发出的磁场强度增大。
采用上述提供的微型水泵，通过减小金属件500的第一折弯部530与第二折弯部510的壁厚，以增加叶轮组件300与绕线组件600可使用的空间，继而增强叶轮组件300与绕线组件600之间的感应强度，从而提高叶轮组件300对液体的驱动力。
另外，在本实施例中，还可将金属件500的周壁520的壁厚做小，这样可减小叶轮组件300与绕线组件600径向上的距离，以提高叶轮组件300与绕线组件600的感应强度，以达到提高叶轮组件300驱动力的目的。
可以理解的是，为了防止金属件500对叶轮组件300与绕线组件600产生干扰，金属件500采用无磁材料。基于金属件500的物理特性，可在保证金属件500强度的前提下，有效减小金属件500的壁厚，从而进一步地增加叶轮组件300与绕线组件600的使用空间。
优选地，该金属件500为无磁钢片。当然，对于金属件500的材质的选择，还可以采用无磁合金、无磁铸铁等。
再者，为了获得更好的生产工艺，在本实施例中，安装壳100、金属件500以及安装件400为一体成型。可以理解的是，现有技术中，微型水泵的安装壳100多为注塑成型。本实施例中，在注塑安装壳100之后，将第一折弯部530与安装壳100抵接，第二折弯部510与安装件400抵接，再通过二次成型工艺，使得安装壳100、金属件500以及安装件400为一体。采用上述工艺，操作简单，且无需为金属件500以及安装件400增加固定结构。采用上述工艺所获得的产品，结构强度可靠，且密封效果较佳，避免了第一收容腔142内的液体流入第二收容腔144。
具体地，请参阅图5，安装壳100开设有与第一折弯部530适配的第一安装槽126，第一折弯部530固定在第一安装槽126内。第一安装槽126对第一折弯部530起到定位的作用，以便于将金属件500放置在安装壳100上。另外，在安装壳100与金属件500的成型工艺中，第一安装槽126的设计，可增加安装壳100与第一折弯部530的接触面积，从而使得成型后的安装壳100与第一折弯部530的连接处强度更高，密封效果更好。
请参阅图2与图5，第二折弯部510中空形成与安装件400适配的通孔512，安装件400固定在通孔512处。采用该结构，可减小第二折弯部510的质量，以使得第二折弯部510轻量化。另外，采用通孔512的设计，可便于下文中安装件400与叶轮组件300的连接。
具体地，安装件400开设有与第二折弯部510适配的第二安装槽402，第二折弯部510固定在第二安装槽402内。第二安装槽402对第二折弯部510起到定位的作用，以便于将金属件500放置在安装壳100上。另外，在安装壳100与金属件500的成型工艺中，第二安装槽402的设计，可增加安装壳100与第二折弯部510的接触面积，从而使得成型后的安装壳100与第二折弯部510的连接处强度更高，密封效果更好。
具体地，请继续参阅图2，叶轮组件300包括套设在周壁520的外周且可环绕绕线组件600转动的磁钢320以及套设在磁钢320的外周的叶轮310；磁钢320的端面与第一折弯部530正对且间隔设置。该磁钢320即为与绕线组件600感应的部件，由于绕线组件600设置在周壁520的内圈，该磁钢320沿轴向上的长度越长，其受到来自绕线组件600的力越大。
另外，叶轮组件300的外周设有多个环绕所述叶轮组件300中心布置的叶片312，该叶片312用于对第一收容腔142内的液体施加推力。
具体地，请继续参阅图2，绕线组件600包括铁芯骨架620以及多个绕线组610；铁芯骨架620套设且固定在安装件400的外周，铁芯骨架620与第二折弯部510正对且间隔设置，多个绕线组610绕设在铁芯骨架620上。
需要补充的是，该铁芯骨架620包括套设在安装件400的外周的安装部以及多个环绕所述安装部均匀设置的绕线部，该绕线部与周壁520抵接。多个绕线组610分别绕设在相邻绕线部之间的间隔中。需要补充的是，该绕线部与第二折弯部510之间的间隔越大，能够绕线的圈数越多，绕线组件600所产生的安培力也越大。
再者，安装件400靠近第一收容腔142的一侧设有固定于所述安装件的固定轴410，固定轴410与叶轮组件300转动连接。具体地，该安装件400于该侧设有收容该固定轴410的固定槽。当然，固定槽内的轴承、轴承安装座等部件不一一阐述。通过安装件400安装固定轴410，再通过固定轴410与叶轮组件300连接，这样极大程度简化了微型水泵的内部空间，以提高微型水泵的结构紧凑性。
另外，值得一提的是，请参阅图3以及图5，叶轮310的外周设有多个环绕叶轮310中心设置的叶片312，安装壳100的内壁凹陷形成有用于容纳液体的容纳槽150，容纳槽150与第一收容腔142连通，安装壳100还贯彻开设有均与容纳槽150连通的进液通道122以及出液通道124，叶片312转动带动容纳槽150内的液体朝出液通道124流出。
安装壳100包括环设在叶轮组件300的外周的壳体120以及用于封盖壳体120的盖板110；盖板110与壳体120盖合形成容纳腔140。上述结构中，壳体120与金属件500以及安装件400一体成型，盖板110再通过螺栓或者其它固定方式与壳体120连接。采用这种结构，可节约生产成本与效率。
进一步地，请参阅图3以及图4，于盖板110以及壳体120的盖合处，盖板110朝内凹陷形成密封槽112，该密封槽112内设有用于防止第一收容腔142内液体溢出的密封圈130。可选地，该密封圈130可以是圆形密封圈130、方形密封圈130、Y型密封圈130或者V型密封圈130等。当然，也可在壳体120处开设密封槽112以及密封圈130，与前者起到相同的效果。
另外，为了实现液体进出第一收容腔142的功能，在本实施例中，壳体120上设有进液通道122以及出液通道124。进液通道122与出液通道124分别与第一收容腔142连通。
如图1或2，该微型水泵还包括电路板200，该电路板200用于控制叶轮组件300与绕线组件600的工作。
以上所述的仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
