Abstract: The present invention discloses a pressing pump and a liquid container. The pressing pump comprises a pump body, a one-way valve, a valve stem assembly, a pressing head and an annular part. The pump body is provided with an accommodating cavity. The annular part is inserted into the accommodating cavity, and the outer circumference of the annular part sealably abuts against an inner wall of the accommodating cavity. The pressing head is provided with a second channel which communicates with the first channel. The second channel has a first opening which is disposed on the side wall of the pressing head close to the pump body and is located at an outer side of the annular part. The pressing pump provided in the present invention can reduce the circumstances in which external moisture enters the interior of the pump body, and improve the waterproof performance.
