The present disclosure relates to a nozzle fixing assembly and a water pick. The nozzle fixing assembly is configured to mount a nozzle having a limiting groove. The nozzle fixing assembly includes: a locking assembly including a housing provided with a first through hole and an elastic element connected to the housing; a support base including an elastic piece and a locking sleeve provided with a second through hole. An outer periphery of the locking sleeve is provided with a latching groove in communication with the second through hole. The nozzle extends through the first through hole and the second through hole and biases the elastic element, such that the limiting groove is aligned with the latching groove, the elastic piece is engaged in the limiting groove and the latching groove.

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.
