Abstract

The present disclosure relates to a water pumping device for a water flosser, which includes a mounting base, a transmission assembly, a connecting member, and a piston. The transmission assembly includes a first transmission member. The connecting member is disposed in the mounting base in a reciprocally movable manner in a first direction. The first transmission member is rotatable about a first rotation axis perpendicular to the first direction, and in mating connection with the connecting member. The first transmission member is eccentrically disposed with respect to the first rotation axis. During a rotation of the first transmission member about the first rotation axis, the first transmission member reciprocates in the first direction, so as to drive the connecting member to reciprocate in the first direction. The reciprocation of the connecting member in the first direction can drive the piston to reciprocate in the first direction.
