Water suction pump

The invention discloses a water suction pump which comprises a driving motor, a cam, a lifting arm, a water suction pipe and a non-return mechanism. The driving motor drives the cam to rotate; the lower end of the lifting arm is connected with the cam; the cam rotates to drive the lifting arm to move up and down in a reciprocating manner; the upper end of the lifting arm is connected with the water pumping pipe through a connecting mechanism, and the lifting arm drives the water pumping pipe to move up and down; the non-return mechanism is arranged at the lower end of the water pumping pipe. The device has the beneficial effects that through the linkage effect of the driving motor, the cam and the lifting arm, manual water pressing is avoided, and the water outlet efficiency can be improved. 本发明公开了一种抽水泵，包括有驱动电机、凸轮、升降臂、抽水管和止逆机构；所述驱动电机驱动凸轮转动；所述升降臂下端与凸轮连接；所述凸轮的转动带动升降臂的上下往复移动；所述升降臂上端通过连接机构与抽水管连接，且升降臂带动抽水管上下移动；所述止逆机构设置在抽水管下端。本发明的有益效果是：本发明通过驱动电机、凸轮和升降臂的联动作用，避免了人工压水，有利于提高出水效率。
