Specifically, the filling portion 210 and the connecting portion 220 are integrally formed through an injection molding process. The filling portion 210 functions to compress/release the cavity of the pump body 100, and the connecting portion 220 functions to transmit power. The filling part 210 is of a solid structure, so that the soft rubber piston 200 can sufficiently eliminate stress and has good sealing performance.
In this embodiment, the diameter of the filling portion 210 gradually increases from an end close to the connecting portion 220 to an end far from the connecting portion 220. In a natural state, a diameter of one end of the filling portion 210 is larger than an inner diameter of the pump body 100, so that the filling portion 210 and the pump body 100 can be connected in an interference manner. The filling part 210 can constantly compensate for the generated abrasion due to the structural shape, and the liquid is prevented from being taken out of the soft rubber piston 200 in the reciprocating process.
