具体实施方式
实施例一
如图1-图4所示，一种电磁泵，包括驱动机构以及在驱动机构的驱动下产生变化磁场的磁性组件2。其中，驱动机构可以为电机1，参见图4，磁性组件2包括底座201、定位套202和多个间隔设置的磁组。每个磁组均包括间隔设置的第一磁体203和第二磁体204，第一磁体203靠近磁组的第一端的磁极极性与第二磁体204靠近磁组的第一端的磁极极性相反。底座201与电机1的输出轴固定连接，以保证磁组在驱动机构的驱动下绕磁性组件2的轴线转动。定位套202固定于底座201上，定位套202上设置有多个间隔设置的且绕磁性组件2的轴线排列的第一安置槽和第二安置槽，第一磁体203位于第一安置槽中，第二磁体204位于第二安置槽中。可选地，第一磁体203靠近磁组的第一端(远离电机1的一端)的磁极极性与第二磁体204靠近磁组的第一端(远离电机1的一端)的磁极极性相反指：第一磁体203靠近磁组的第一端的磁极是S极且第二磁体204靠近磁组的第一端的磁极是N极，第一磁体203远离磁组的第一端的磁极是N极且第二磁体204远离磁组的第一端的磁极是S极；或者，第一磁体203靠近磁组的第一端的磁极是N极且第二磁体204靠近磁组的第一端的磁极是S极，第一磁体203远离磁组的第一端的磁极是S极且第二磁体204远离磁组的第一端的磁极是N极。
可选地，当电机1工作时，磁性组件2绕自身的轴线转动，第一磁体203和第二磁体204也随之转动，由于第一磁体203与第二磁体204同一端的磁极极性不同，所以当第一磁体203和第二磁体204发生转动时，磁性组件2就可以产生一个交替变化的磁场。由于第一磁体203与第二磁体204绕磁性组件2的轴线排列，所以磁性组件2产生的磁场的状态变化也是周期性的，磁性组件2转动一圈为一个周期，所以磁性组件2的转动可以产生一个稳定的磁场。相关 技术中的电磁泵是通过交变电流产生交变磁场，本实施例中的电磁泵是直接用磁体产生变化的磁场(磁场的强度和方向均有变化)，电能损耗更少，转换效率更高。本实施例中的电磁泵无需使用高电压即可产生较强的磁场，生产过程更加安全，可靠性更高。
电磁泵还包括容箱3和喷液装置4。用非导磁的材料制成的容箱3的上部设有进料管303，容箱3的下部设有排渣管，容箱3的底部的出液区域设有第一凹槽301和环绕在第一凹槽301外部的第二凹槽302，第二凹槽302的第一端与第一凹槽301连通。喷液装置4包括贴合设置于出液区域的上方的且用导磁材料制成的封板401和位于封板401的上方的导流柱402，喷液装置4还包括位于容箱3的外部的喷嘴403；导流柱402远离第一凹槽301的一端与喷嘴403连通。封板401上设有与第二凹槽302的第二端连通的第一通孔4011，导流柱402的底部与第一凹槽301连通。磁性组件2位于容箱3的下方且导流柱402的轴线与磁性组件2的轴线在一条直线上；磁性组件2与容箱3之间设有间隙，磁性组件2与容箱3之间没有接触，可以减少摩擦。可选地，来料从进料管303进入容箱3，容箱3中设有加热装置以保证来料保持液态的状态，当磁性组件2转动产生一个稳定的磁场时，容箱3中的液态金属在磁场的驱动下经过第一通孔4011流进第二凹槽302，然后从第二凹槽302流进第一凹槽301，再从第一凹槽301流到导流柱402中，导流柱402中的液态金属在磁场的驱动下克服重力和摩擦力等阻力，从喷嘴403流出，流经喷嘴403时，压力增大，以实现增压的目的。
于本实施例中，磁场的强度和交替变化的速度主要与磁组的数量以及电机1的转速有关。根据设计需要，可以将磁组设置为1个、2个、3个、4个甚至更多个。可选地，为了保证对称性，第一磁体203的数量与第二磁体204的数量 相等。
于本实施例中，导流柱402的轴线、磁性组件2的轴线和电机1的轴线在一条直线上。于另一实施例中，导流柱402只要处于磁组产生的磁场中即可，并不一定要与磁性组件2共轴。于另一实施例中，电机1通过齿轮或链条等传动方式驱动磁性组件2绕磁性组件2的轴线转动，电机1与磁性组件2不共轴。
如图5所示，磁感线从第一磁体203出发，往上运动，穿过由非导磁材料制成的容箱3进入到容箱3的内部，穿过容箱3中的液态金属后，进入由导磁材料制成的封板401中，然后往左右两个方向运动，再次经过液态金属和容箱3后，进入第二磁体204中，从第二磁体204出发的磁感线经过由导磁材料制成的底座201回到第一磁体203中，完成循环。如果容箱3由导磁材料制成，则可能出现磁感线在容箱3中就往左右两个方向运动，进而导致大量的磁感线没有穿过液态金属的情况，可能导致电磁泵失效，所以容箱3可以是由非导磁材料制成。如果封板401由非导磁材料制成，则从第一磁体203出发的磁感线会往上穿过封板401，不在封板401中往左右两个方向运动，从而延长了磁感线回路，降低工作效率，所以封板401可以是由导磁材料制成。同理，底座201可以是由导磁材料制成。
实施例二
如图6所示，本实施例与实施例一的区别在于：
驱动机构为曲柄连杆机构；曲柄连杆机构包括气缸5和连杆6，连杆6的一端与气缸5的驱动端铰接，连杆6的另一端与磁性组件2的底部铰接。
可选地，连杆6可以将气缸5的直线运动转化为磁性组件2的圆周运动，使磁性组件2绕磁性组件2的轴线转动以产生变化的磁场。
本文中的“第一”、“第二”等仅仅是为了在描述上加以区分，并没有特殊的含义。
在上述具体实施方式中所描述的多个技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合，为了避免不必要的重复，本公开对多种可能的组合方式不再另行说明。
工业实用性
本公开提供的电磁泵是直接用磁体产生变化的磁场(磁场的强度和方向均有变化)，电能损耗更少，转换效率更高。
