One end of the piston rod 313 is connected to the piston 312, and the other end of the piston rod 313 is connected to a link 322 included in the reciprocating drive mechanism 32. The piston rod 313 serves to drive the piston 312 to reciprocate in the piston cylinder 311 when the connecting member 322 is driven to reciprocate. When the reciprocating drive mechanism 32 drives the piston rod 313 to reciprocate, the piston 312 is driven to reciprocate in the piston cylinder 311, and when the piston 312 moves towards the water outlet 3111, the liquid in the piston cylinder 311 is pushed to be discharged from the water outlet 3111; when the piston 312 moves toward the water inlet 3142 while sucking the liquid in the water reservoir 11 into the piston cylinder 311, the liquid in the piston cylinder 311 flows toward the water outlet 3111 through the piston 312, so that the liquid in the piston cylinder 311 is pushed to be discharged from the water outlet 3111 when the piston 312 moves toward the water outlet 3111. The piston 312 is driven by the piston rod 313 to move in the piston cylinder 311 so as to pump water, and the water pump is simple in structure, convenient to assemble and low in cost.

In one embodiment, the piston cylinder 311 may be integrally formed at the bottom of the water storage tank 11, so as to ensure good structural strength of the piston cylinder 311 and the water storage tank 11, and facilitate manufacturing.
