Abstract
An all-plastic combined press pump includes a lock bottle, a pump body and a locking cap capable of fixing the pump body on the lock bottle. A liquid storage chamber, a communication port communicated with the liquid storage chamber, a one-way valve, and a pumping assembly slidable up and down are disposed in the pump body. A press head for driving the pumping assembly to move downwards is disposed at an upper end of the pumping assembly. A plastic spring for elastically pressing the press head to drive the pumping assembly to reset upwards to enable negative pressure in the liquid storage chamber to be generated so as to open the one-way valve to suck the liquid into the liquid storage chamber is disposed between the locking cap and the press head.
