A press-type liquid pump comprising a fixed unit and a movable unit capable of making a reciprocative movement relative to the fixed unit. The reciprocative movement is implemented jointly by a pressing force exerted by a user onto the movable unit and by a flexible resetting apparatus allowing the movable unit to reset relative to the fixed unit when the pressing force is withdrawn. The flexible resetting apparatus is a plastic flexible compression apparatus arranged below a toothed cover (140) and between the fixed unit and the movable unit. The plastic flexible compression apparatus comprises at least one flexible strip (111) mostly in the shape of an arc. The pump solves the problem that a metal spring is difficult to recycle and is of increased costs, and that an existing plastic spring liquid pump provides a hard-to-press sensation and insufficient rebound force. |
