Abstract
A water pump connecting structure for an oral irrigator, including: a pump body, a piston ring, a connecting rod assembly, and a driving assembly. The piston ring is arranged on the inner side wall of the pump body, the connecting rod assembly penetrates into the pump body and penetrates through the piston ring. The piston ring is in interference connection with the connecting rod assembly. The connecting rod assembly is connected to the driving assembly and makes reciprocating motion in the pump body through the driving of the driving assembly and the guidance of the piston ring. The connecting rod assembly and the piston ring are configured to cooperate with each other to draw liquid from a water inlet of the pump body and to pump the liquid out from a water outlet of the pump body, during reciprocating motion of the connecting rod assembly.
